                               PROSPECTUS SUMMARY
 
   This summary contains basic information about us and this offering. Because
it is a summary, it does not contain all of the information that you should
consider before investing. You should read the entire prospectus carefully,
including the section entitled "Risk Factors" and our consolidated financial
statements and the notes thereto before making an investment decision. Unless
otherwise indicated or required by the context, references to years in this
prospectus refer to our fiscal years. In this prospectus, Divicore, "we," "us,"
and "our" refers to Divicore Inc. but not to the underwriters listed in this
prospectus.
 
                                 Divicore Inc.
 
   We design, develop, license and market innovative core-based modular
software solutions that enable digital video and audio stream management in
personal computer systems and consumer electronics devices. We also license
supporting hardware designs to selected customers and provide customization
services and customer support. Our solutions enable decoding (playback) and
encoding (recording) of multimedia formats such as digital versatile disk, or
DVD; direct broadcast satellite, or DBS, or its European counterpart, digital
video broadcasting or DVB; and high definition television, or HDTV, on existing
personal computer and consumer electronics platforms. Our digital solutions
incorporate industry standards for video and audio compression, independent of
operating systems and silicon components, and are built using the same
powerful, easily customizable and modular software architecture. As digital
technology continues to evolve and standards change, we can add new modules to
our software to provide additional functionality without needing to alter
existing core components of our digital solution. Moreover, our modular
approach provides our customers with enhanced flexibility and adaptability that
enables the rapid introduction of new products to market. We intend to leverage
the flexibility of our products to capitalize on the shift from analog to
digital content across the media and entertainment industries.
 
   Our products focus on two important markets, the personal computer market
and the consumer electronics market. Our products integrate the same high-
performance software architecture and code base across multiple applications in
each market. This allows personal computer and consumer electronics
manufacturers to achieve faster time-to-market, to cross-market their product
offerings, to develop a customizable, consistent look and feel across product
lines and to reduce technical support costs. Personal computer and peripherals
manufacturers currently shipping products that incorporate our technology
include ATI Technologies Inc., Compaq Computer Corporation, Dell Computer
Corporation, Fountain Technologies, Inc., Fujitsu Microelectronics, Inc.,
Gateway 2000, Inc., Hewlett-Packard Company, Micron Electronics, Inc. and
Packard Bell NEC Europe. Consumer electronics manufacturers that have agreed to
incorporate our technology include Tottori-Sanyo Electric Co., Ltd. (a
subsidiary of Sanyo Electronics Corporation, Inc.) and Yamaha Corporation of
America. We also have strategic relationships with ATI Technologies, Dolby
Laboratories, Inc., Intel Corporation and STMicroelectronics (formerly SGS-
Thomson Microelectronics).
 
   Consumers are increasingly demanding capabilities that analog technology
cannot provide. Meanwhile, digital formats have emerged that provide higher
image resolution and quality, the opportunity to deliver a wide range of new
services and content, more efficient use of limited transmission spectrum and
the ability to deliver customized and interactive services. As a result, a
growing number of consumer electronics manufacturers are using digital
technologies in their video and audio devices. Government regulation and the
expanding digital content market have accelerated this trend. As a result, all
existing television sets, video cassette recorders, stereos, set-top boxes and
personal computers are now candidates for upgrade to digital
technologies. In order to capitalize on upgrade cycles for existing products
and enter new markets, personal
 
                                       3

computer and consumer electronics manufacturers are seeking digital product
solutions that permit rapid time-to-market and incorporate the latest features
and functionality.
 
   Our strategy is to be the leading global provider of digital video and audio
solutions to personal computer and consumer electronics manufacturers. We
believe that the most effective way to achieve our strategy is to license our
technology to manufacturers that will in turn use our solutions to penetrate
very large personal computer and consumer electronics markets. The key elements
of our strategy include growing our licensing business model among top tier
personal computer and consumer electronics manufacturers, extending our
technological leadership, leveraging our technology and expertise into new
markets and focusing on our strategic relationships.
 
   We currently offer two complete solutions for DVD playback on personal
computers. These solutions are incorporated into the products of seven of the
top ten personal computer manufacturers, based on total unit sales. These
include Software CineMaster 98, a software-only solution, and Hardware
CineMaster 98, a software solution with a supporting hardware platform design.
We also offer CineMaster CE, a software solution with multiple supporting
hardware platform designs that enables DVD playback across a variety of
consumer electronics products. CineMaster CE was introduced in late 1998 and
has already achieved design wins from Sanyo Electronics and Yamaha. In
addition, we are developing a software-only DVD encoding solution that enables
the recording of video and audio streams in the DVD format, a software solution
that enables digital television viewing on a consumer electronics device and a
software solution that enables the viewing of digital cable television streams
using a personal computer or digital cable set-top device. Divicore receives a
per unit license fee from personal computer and consumer electronics devices
manufacturers that incorporate its technology in addition to any license fees
it may receive from manufacturers of semiconductors used in these devices.
 
                                ----------------
 
   We were incorporated in Pennsylvania in April 1994 as Quadrant Sales
International, Inc. and changed our name to Quadrant International, Inc. in May
1994. Effective in May 1999, our name will change to Divicore Inc. We are
planning to reincorporate in Delaware prior to the consummation of the
offering.

                 CAUTIONARY NOTE ON FORWARD-LOOKING STATEMENTS
 
   Some of the matters discussed under the captions "Prospectus Summary," "Risk
Factors," "Management's Discussion and Analysis of Financial Condition and
Results of Operations," "Business" and elsewhere in this prospectus include
forward-looking statements. We have based these forward-looking statements on
our current expectations and projections about future events, including, among
other things:
 
    .  implementing our business strategy;
 
    .  obtaining and expanding market acceptance of the products we offer;
 
    .  meeting our requirements with our customers;
 
    .  forecasts of digital video penetration in the personal computer and
       consumer electronics industries;
 
    .  competition in the digital video and audio stream management market;
       and
 
    .  the existence and timing of any consumer shift from analog-based to
       digital-based products and the corresponding development of the
       digital media market.
 
   In some cases, you can identify forward-looking statements by terminology
such as "may," "will," "should," "potential," "continue," "expects,"
"anticipates," "intends," "plans," "believes," "estimates" and similar
expressions. These statements are based on our current beliefs, expectations
and assumptions and are subject to a number of risks and uncertainties. Actual
results and events may vary significantly from those discussed in the forward-
looking statements. A description of certain risks that could cause our results
to vary appears under the caption "Risk Factors" and elsewhere in this
prospectus. These forward-looking statements are made as of the date of this
prospectus, and we assume no obligation to update them or to explain the
reasons why actual results may differ. In light of these assumptions, risks and
uncertainties, the forward-looking events discussed in this prospectus might
not occur.

                                  RISK FACTORS
 
   An investment in our shares is extremely risky. This section describes some,
but not all, of the risks involved in purchasing our common stock. You should
consider carefully the following risks, in addition to the other information
presented in this prospectus, in evaluating us and our business. Any of the
following risks, as well as other risks not mentioned here, could seriously
harm our business and prospects and cause the trading price of our common stock
to decline, which in turn, could cause you to lose all or part of your
investment.
 
                           Risks Related to Divicore
 
We have recently changed our business model, and we have a limited history
operating under our current business model
 
   As a result of our relatively brief operating history as a provider of
digital software solutions, our historical financial information is of limited
value in projecting future operating results. We believe that comparing
different periods of our operating results is not meaningful and you should not
rely on the results for any period as an indication of our future performance.
In addition at some point in the future, these fluctuations may cause us to
perform below the expectations of public market analysts and investors. If our
results were to fall below market expectations, the price of our common stock
may fall significantly. Our limited operating results have varied widely in the
past, and we expect that they will continue to vary significantly from quarter-
to-quarter as we attempt to establish our products in the market. Before
investing, you should consider the risks and challenges frequently encountered
by early stage companies such as ours that are in new and rapidly evolving
markets. In particular, to address these risks we face the following
challenges, among others:
 
     .  increasing demand for our products and services;
 
     .  maintaining and increasing our consumer base;
 
     .  competing effectively with existing and potential competitors; and
 
     .  developing further our new and unproven business model.
 
   Divicore was founded in April 1994 as a provider of hardware-based digital
video solutions. In November 1997 we changed our strategic focus from selling
hardware-based digital solutions to licensing software-based digital solutions,
and in early 1999 we discontinued direct sales of hardware-based solutions
altogether to focus exclusively on licensing software-based solutions and
supporting hardware platform designs. This change required us to adjust our
business processes and make a number of significant personnel changes,
including changes and additions to our engineering and marketing teams. We
cannot be certain that our change in business strategy will be successful or
that we will successfully address these risks. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
You should expect our quarterly operating results to fluctuate in future
periods
 
   Our revenues and operating results will vary significantly from quarter-to-
quarter due to a number of factors, including:
 
    .  variations in demand for our products and services;
 
    .  the timing of sales of our products and services and the timing of
       new releases of personal computer systems, consumer electronics
       devices and semiconductors that incorporate our products;
 
    .  delays in introducing our products and services;
 
    .  changes in our pricing policies or the pricing policies of our
       competitors;
 
                                       9
<PAGE>
 
    .  the timing and accuracy of royalty reports received from our
       customers;
 
    .  the timing of large contracts that materially affect our operating
       results in a given quarter;
 
    .  changes in the usage of digital media;
 
    .  our ability to develop and attain market acceptance of enhancements
       to our CineMaster products;
 
    .  new product introductions by competitors;
 
    .  the mix of license, service and hardware revenues;
 
    .  the mix of domestic and international sales;
 
    .  costs related to acquisitions of technologies or businesses;
 
    .  our ability to attract, integrate, train, retain and motivate a
       substantial number of sales and marketing, research and development,
       administrative and product management personnel;
 
    .  our ability to expand our operations; and
 
    .  global economic conditions as well as those specific to personal
       computer, consumer electronics, peripherals and semiconductor
       manufacturers and other providers of digital video and audio stream
       management solutions.
 
   We plan to significantly increase our operating expenses to expand our sales
and marketing operations, broaden our product management and customer support
capabilities and fund greater levels of research and development. We determine
our operating expenses largely on the basis of anticipated revenue trends and a
high percentage of our expenses are fixed in the short term and are
significant. As a result, any delay in generating or recognizing revenue could
cause significant variations in our operating results from quarter-to-quarter
and could result in substantial operating losses.
 
   Due to the foregoing factors, we believe that quarter-to-quarter comparisons
of our operating results are not a good indication of our future performance.
In future quarters, our operating results may be below the expectations of
public market analysts and investors. In this event, the price of our common
stock may fall significantly. See "--Our license revenue is based upon a
customer sales report and we have never audited our customers" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
We have a history of losses and we may not be able to achieve profitability in
the future
 
   We incurred net losses of approximately $0.3 million for the three months
ended March 31, 1999, $13.7 million for the year ended December 31, 1998, $7.3
million for the year ended December 31, 1997 and $2.1 million for the year
ended December 31, 1996. As of March 31, 1999, we had an accumulated deficit of
approximately $25.2 million. To date, we have not achieved profitability on a
quarterly or annual basis, and we may not achieve sufficient revenues to
generate profitability in any future period. If we do achieve profitability, we
cannot be certain that we can sustain or increase profitability on a quarterly
or annual basis. In addition, we expect to significantly increase our sales and
marketing, product development, engineering and administrative expenses to
grow. As a result, we will need to generate significant revenues to achieve and
maintain profitability.
 
Our prices may decline as our products becomes commoditized
 
   We expect our prices for our CineMaster products to decline over the next
few years. Most of our current revenues are derived from license fees
originating from sales of personal computer systems which use our Software
CineMaster product as their DVD solution. We expect to face increased
competition in this market, which will make it more difficult to maintain our
revenues and profit margins even if our sales volumes increase. If anticipated
increases in sales volume did not keep pace with anticipated pricing pressures,
our revenues would decline and our business could be harmed. Despite our
efforts to introduce enhancements to our products, we may not be successful in
maintaining our pricing. See "Selected Consolidated Financial Data" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
                                       10
<PAGE>
 
Our business currently depends upon our CineMaster products, and it is
uncertain whether the market will continue to accept these products
 
   During 1997 and 1998, we derived virtually all of our license revenues from
the sale of personal computers and peripherals incorporating our CineMaster
products. We expect that license revenues from our CineMaster products will
continue to account for a significant portion of our revenues for the
foreseeable future. In particular, our business will be harmed if our existing
manufacturing customers do not continue to incorporate our CineMaster products
or if we are unable to obtain new customers for our CineMaster products. In
seeking market acceptance, it may be difficult for our digital solutions to
displace incumbent solutions employed by manufacturers not currently licensing
our CineMaster products. Manufacturers that are using other solutions would
need to invest in additional training and development tools and convert
software for existing hardware solutions in order to change to a new digital
solution. Accordingly, potential customers may not accept our digital
solutions, which could limit our growth opportunities and harm our prospects.
See "Business--Products and Services."
 
Our business is currently dependent on a small number of customers
 
   A substantial portion of our license revenues come from three customers,
Dell Computer Corporation, ATI Technologies Inc. and Gateway 2000, Inc. During
1998, Dell Computer accounted for over 81% of our total revenues and 40% of our
gross profit, while ATI Technologies accounted for over 6% of total revenues
and 27% of gross profit. In the quarter ending March 31, 1999, Dell Computer,
ATI Technologies and Gateway accounted for 75%, 6% and 11% of our total
revenues and 27%, 18% and 29% of our gross profit, respectively. We expect a
relatively small number of customers to account for a majority of our revenues
and gross profit, if any, for the foreseeable future. The loss of any of these
or other primary customers, or a material decrease in revenue from these
customers, would immediately harm our business. As a result of our concentrated
customer base, we are subject to risks beyond our control that influence the
success or failure of a particular personal computer or consumer electronics
manufacturer, any one of which could harm our business, including:
 
    .  the competition the manufacturer faces and the market acceptance of
       its products;
 
    .  the engineering, marketing and management capabilities of the
       manufacturer and the technical challenges unrelated to our
       technology that it faces in developing its products;
 
    .  the financial and other resources of the manufacturer;
 
    .  new governmental regulations or changes in taxes or tariffs
       applicable to the manufacturer; and
 
    .  the failure of third parties to develop and introduce content for
       DVD and other digital media applications in a timely fashion.
 
The inability of us or our customers to successfully address any of these risks
could harm our business. See "Business--Customers."
 
We do not have long term commitments with our customers
 
   Many of our licensing relationships are of limited duration and do not
contain minimum purchase commitments or are terminable with little or no
notice. As a result, these customers may elect not to incorporate our products
into their products at any time in the future, and we could have little warning
of this election. In any event, we could be required to reach an accommodation
with our customers with respect to any possible contractual provision in order
to obtain additional business and maintain our customer relationships. Any
termination, decrease in orders or election not to renew a contract by our
principal customers would harm our business.
 
   In addition, many of our relationships, including certain relationships with
Dell Computer and Gateway, are not currently governed by definitive written
agreements. In particular, dispute exists with these customers over our
respective liabilities and with respect to potential litigation involving
proprietary rights, including litigation concerning patents related to the
video compression standard known as MPEG-2. Without
 
                                       11
<PAGE>
 
these agreements, we could be required to pay damages or to reimburse our
customers for damages that could arise as a result of litigation related to
this technology.
 
   We have not transferred responsibility for manufacturing and storing the
hardware platform components for our Hardware CineMaster product to a third
party. If we are unable to conclude a definitive manufacturing agreement with
Dell Computer, we will remain liable for the manufacture, storage and delivery
of this product and our business might be harmed. Moreover, the completion of
our transformation from a sales revenue model to a licensing revenue model
could be substantially delayed.
 
Our success is dependent upon both manufacturers who license our products and
our strategic relationships
 
   Our revenues now consist principally of license fees paid by our customers
for our software solutions and supporting hardware designs. Our products are
currently licensed to personal computer, consumer electronics and peripherals
manufacturers whose products are then sold to end users, and to semiconductor
manufacturers whose products are sold to manufacturers. Our digital solutions
may not be used in a product that is ultimately brought to market, achieves
commercial acceptance or generates meaningful license fees for us. Furthermore,
because we do not control the business practices of our licensees, we do not
influence the degree to which our licensees promote our technology or set the
prices at which the products incorporating our technology are sold to end
users. We face numerous risks in successfully obtaining licensees on terms
consistent with our business model. These risks include, among others:
 
    .  the lengthy and expensive process of building a relationship with a
       potential licensee before there is any assurance of a license
       agreement with such party;
 
    .  persuading potential licensees to bear certain development costs
       associated with our technology; and
 
    .  successfully transferring technical know-how to licensees.
 
There are a limited number of personal computer and consumer electronics
manufacturers to which we can license our technology in a manner consistent
with our business model.
 
   We rely on certain strategic relationships, such as those with Intel
Corporation, STMicroelectronics, Inc., Dolby Laboratories Licensing Corporation
and ATI Technologies to provide us with state of the art technology, assist us
in integrating our products with leading industry applications and help us make
use of economies of scale in manufacturing and distribution. The loss of any
one of these relationships could harm our business. See "Business--Sales and
Marketing."
 
Delays in providing our products to our customers may affect how much business
we receive
 
   Our product development efforts may not be successful and we may encounter
significant delays in bringing our products to market. Given the short product
life cycles in our industry, if our product development efforts are not
successful or are significantly delayed, our business will be harmed. In the
past, we have failed to deliver certain new products, upgrades or
customizations on time. In the future, our efforts to remedy this situation may
not be successful and we may lose customers as a result. Delays in bringing to
market new products, enhancements to old products or interfaces between
existing products and new models of personal computers or consumer electronics
devices could be exploited by our competitors. If we were to lose market share
as a result of lapses in our product management, our business would be harmed.
 
We may not be successful in protecting our proprietary rights
 
   Our ability to compete depends substantially upon our internally developed
technology. We have a comprehensive program for securing and protecting rights
in patentable inventions, trademarks, trade secrets and copyrightable
materials. If we are not successful in protecting our intellectual property,
our business could be substantially harmed.
 
                                       12
<PAGE>
 
   Patents. We regard the protection of patentable inventions as important to
our future opportunities. We currently have three U.S. patent applications
pending relating to our digital video and audio stream management technology.
However, none of our technology is patented outside of the United States nor do
we currently have any international patent applications pending. It is possible
that:
 
    .  our pending patent applications may not result in the issuance of
       patents;
 
    .  our patents may not be broad enough to protect our proprietary
       rights;
 
    .  any issued patent could be successfully challenged by one or more
       third parties, which could result in our loss of the right to
       prevent others from exploiting the inventions claimed in those
       patents;
 
    .  current and future competitors may independently develop similar
       technology, duplicate our products or design around any of our
       patents; and
 
    .  effective patent protection may not be available in every country in
       which we do business.
 
   Trademarks, Copyrights and Trade Secrets. We rely on a combination of laws,
such as copyright, trademark and trade secret laws, and contractual
restrictions, such as confidentiality agreements and licenses, to establish and
protect our proprietary rights. We currently have a pending trademark
application for the mark "Divicore" and a second pending trademark application
for the mark "CineMaster" which has been approved for publication by the PTO.
However, none of our trademarks are registered outside of the United States,
nor do we have any trademark applications pending outside of the United States.
Moreover, despite any precautions which we have taken:
 
    .  laws and contractual restrictions may not be sufficient to prevent
       misappropriation of our technology or deter others from developing
       similar technologies;
 
    .  other companies may claim common law trademark rights based upon
       state or foreign law which precede our federal registration of such
       marks;
 
    .  current federal laws that prohibit software copying provide only
       limited protection from software "pirates," and effective trademark,
       copyright and trade secret protection may be unavailable or limited
       in certain foreign countries;
 
    .  policing unauthorized use of our products and trademarks is
       difficult, expensive and time-consuming and we are unable to
       determine the extent to which piracy of our products and trademarks
       may occur, particularly overseas;
 
    .  we have provided our source code for Software CineMaster to certain
       customers as part of our licensing arrangements with them and the
       procedures and practices implemented under the terms of these
       licenses may not be sufficient to prevent these customers from
       exploiting the source code; and
 
    .  we have not currently embedded any copy protection in our software
       because we do not believe that these mechanisms are practical or
       cost-effective.
 
See "Business--Intellectual Property and Proprietary Rights."
 
We may become involved in litigation over proprietary rights, which may be
costly and time consuming
 
   Substantial litigation regarding intellectual property rights exists in our
industry. We expect that software and hardware in our industry may be
increasingly subject to third-party infringement claims as the number of
competitors grows and the functionality of products in different industry
segments overlaps. Third parties may currently have, or may eventually be
issued, patents that would be infringed by our products or technology. We
cannot be certain that any of these third parties will not make a claim of
infringement against us with respect to our products and technology.
 
                                       13
<PAGE>
 
   Any litigation, brought by us or others, could result in the expenditure of
significant financial resources and the diversion of management's time and
efforts. In addition, litigation in which we are accused of infringement may
cause product shipment delays, require us to develop non-infringing technology
or require us to enter into royalty or license agreements even before the issue
of infringement has been decided on the merits. If any litigation were not to
be resolved in our favor, we could become subject to substantial damage claims
and be enjoined from the continued use of the technology at issue without a
royalty or license agreement. These royalty or license agreements, if required,
might not be available on acceptable terms, or at all, and could harm our
business. If a successful claim of infringement were made against us and we
could not develop non-infringing technology or license the infringed or similar
technology on a timely and cost-effective basis, our business could be
significantly harmed.
 
   From time to time, we have received, and we expect to continue to receive,
notice of claims of infringement of other parties' proprietary rights. For
example:
 
    .  Our digital video stream management solutions comply with industry
       DVD specifications, which incorporate a video compression technology
       known as MPEG-2. We have recently received notice from two of our
       customers which are personal computer manufacturers that a third
       party with substantial financial resources has alleged that aspects
       of MPEG-2 technology infringe upon patents held by the third party.
       These customers may in the future seek compensation or
       indemnification from us arising out of the third-party claims.
       Moreover, we may be required to pay license fees in connection with
       the use of the third party's technology in the future.
 
    .  A group of companies comprised of consumer electronics manufacturers
       has formed a consortium known as MPEG-LA to enforce the proprietary
       rights of other holders of patents covering essential aspects of
       MPEG-2 technology that are incorporated into our products. MPEG-LA
       has notified a number of personal computer manufacturers, including
       our customers, that patents owned by members of the consortium are
       infringed by the personal computer manufacturers in their
       distribution of products that incorporate the MPEG-2 technology.
       MPEG-LA has requested that these personal computer manufacturers pay
       license fees for use of the technology covered by MPEG-LA patents.
       These personal computer manufacturers may in the future seek
       compensation or indemnification from us arising out of the MPEG-LA
       claims, and we may be required to pay license fees in connection
       with the use of MPEG-2 technology in the future.
 
    .  A third party has asserted that the parental control features of our
       CineMaster products infringe certain patents held by the third
       party. A court could determine that we did infringe these patents
       and we would be liable for resulting damages.
 
Any of these notices could result in litigation, which would include all of the
risks discussed above. See "Business--Intellectual Property and Proprietary

Our success depends on our ability to successfully manage growth and integrate
businesses or technologies which we may acquire in the future
 
   Our ability to successfully offer our CineMaster products and other products
and services in a rapidly evolving digital video and audio stream management
market requires an effective planning and management process. In addition, we
have limited experience in managing rapid growth. In the last several months,
we have added engineering, sales, marketing, administrative and other
management personnel. Our business will suffer dramatically if we fail to
manage this growth. On March 31, 1999, we had a total of 106 employees compared
to a total of 30 employees on March 31, 1998. Our growth so far has placed
strains on our managerial, financial and personnel resources. We expect these
strains to continue in the future. The pace of our expansion, together with the
complexity of the technology involved in our products, demands an unusual
amount of focus upon the operational needs of our customers for quality,
reliability, timely delivery and post-installation field support. Our existing
licenses rely heavily on our technical expertise in customizing our digital
solutions to their new products. In addition, relationships with new
manufacturing customers generally require significant
 
                                       14
<PAGE>
 
engineering support. Therefore, any increases in adoption of our products by
existing or new customers will increase the strain on our resources, especially
our engineers. To reach our goals, we will need to continue hiring on a rapid
basis while, at the same time, investing in our infrastructure. We will also
need to increase the scale of our operations. We expect that we will also have
to expand our facilities, and we may face difficulties identifying and moving
into suitable office space. In addition, we will need to:
 
    .  successfully train, motivate and manage new employees;
 
    .  expand our sales and support organization;
 
    .  integrate new management and employees into our overall operations;
 
    .  implement a more effective cash management system;
 
    .  adopt and staff an investor relations program; and
 
    .  establish improved financial and accounting systems.
 
   In the future, from time to time, we may make acquisitions or investments in
other companies, products or technologies. If we make any acquisitions, we will
be required to assimilate the operations, products and personnel of the
acquired businesses and train, retain and motivate key personnel from the
acquired businesses. We may be unable to maintain uniform standards, controls,
procedures and policies if we fail in these efforts. Similarly, acquisitions
may cause disruptions in our operations and divert management's attention from
day-to-day operations, which could impair our relationships with our current
employees, customers and strategic partners.
 
   We may not succeed in anticipating all of the changing demands that growth
will impose on our systems, procedures and structure. If we fail to effectively
manage our expansion, our results of operations will suffer. See "Business--
Divicore's Strategy" and "--Employees."
 
Our success depends upon our management and our ability to attract and retain
additional personnel in a competitive market
 
   Our success depends on the efforts and abilities of our senior management
and certain other key personnel, particularly technical personnel in our
engineering subsidiary in Germany. Many of our officers and key employees are
employed at will. In addition, Mr. Wilde and the principal engineers in our
German subsidiary, Messrs. Sigmund, Horak and Ringelberg, are the only
employees upon whom we have obtained key man life insurance and we do not
expect to obtain such insurance on any of our other senior managers. If any of
these or other key employees left or was seriously injured and unable to work
and we were unable to find a qualified replacement, then our business could be
harmed. We have recently hired new managers and intend to continue hiring key
management personnel. We may not be able to successfully assimilate our
recently hired managers or to hire qualified key management personnel to
replace them.
 
   We intend to hire a significant number of additional sales, support,
marketing, engineering and product management personnel in 1999 and beyond.
Competition for these individuals is intense, and we may not be able to
attract, assimilate or retain additional highly qualified personnel in the
future. Hiring qualified personnel, particularly sales, marketing, engineering
and product management personnel, is very competitive in our industry due to
the limited number of people available with the necessary technical skills and
understanding of the digital video and audio stream management industry. In
addition, we are headquartered in Malvern, Pennsylvania and we have in the past
and expect in the future to face difficulties locating qualified personnel in
this location. We expect to face greater difficulty attracting these personnel
with equity incentives as a public company than we did as a privately held
company. See "Business--Employees."
 
We may not be able to successfully integrate our newest subsidiary
 
   In April 1998, we completed the acquisition of Viona. However, we may not be
able to successfully integrate the two companies. Combining our companies
requires, among other things, integrating our respective
 
                                       15
<PAGE>
 
technologies, coordinating our research and development and financial reporting
efforts, and continuously evaluating whether existing systems and procedures
meet our growth requirements, especially our financial and internal control
systems and management structure. Certain aspects of the integration are still
in process and may not be completed smoothly or successfully. If we fail to
integrate these areas, we may be unable to maintain uniform standards,
procedures, controls and policies. Integrating certain operations may require
our management to dedicate resources which may temporarily distract them from
our day-to-day business, including from the development of new products, which
could result in delays in introducing such products. Coordinating
geographically separated organizations with distinct cultures may increase the
difficulty of our integration. If we fail to successfully complete the
integration of Viona's operations, our business could be harmed.
 
Our products may be defective and we may lose business or be sued as a result
 
   Products as complex as our CineMaster products frequently contain undetected
errors. The likelihood of errors is higher when a new product is introduced or
when new versions or enhancements are released. Despite our extensive quality
assurance process, we have in the past shipped product releases with some
defects, and have discovered other errors in our products after their
commercial shipment. Despite our quality assurance process and that of our
customers, defects and errors may be found in new products or in new versions
or enhancements of existing products after commercial shipment has begun. We
may be required to devote significant financial resources and personnel to
correct such defects. Known or unknown errors or defects that affect the
operation of our products could result in the following, any of which could
harm our business:
 
    .  delay or loss of revenue;
 
    .  cancellation of customer contracts;
 
    .  diversion of development resources;
 
    .  damage to our reputation;
 
    .  increased service and warranty costs; and
 
    .  litigation costs.
 
   Many of our licenses with customers contain provisions designed to limit our
exposure to potential product liability claims, such as disclaimers of
warranties and limitations on liability for special, consequential and
incidental damages. However, these contractual limitations on liability may not
be enforceable and we may be subject to claims based on defects in our products
or mistakes in performing our services. Our product liability insurance may not
be adequate to cover our losses in the event of a product liability claim
resulting from such defects. Moreover, we may not be able to maintain such
insurance. A product liability claim may harm our financial condition and
results of operations.
 
   Our products incorporate and are used with other companies' products.
Defects, including those in other companies' products, discovered in the future
could result in adverse customer reaction, negative publicity, delays in our
product installation or delays in or failure to achieve market acceptance of
our products. Any of these results could harm our business. See "Business--
Products and Services."
 
Our license revenue is based upon customer sales reports and we have never
audited our customers
 
   We receive a license royalty for each personal computer system, peripheral
or consumer electronics product sold that contains our Software CineMaster
product and a royalty for each silicon device sold by a semiconductor
manufacturer that incorporates our technology. In collecting these fees,
preparing our financial reports, projections and budgets and in directing our
sales efforts and product development, we rely on our customers to accurately
report the number of units sold. We have never undertaken an audit of any of
our customers to verify that its reported sales unit numbers were accurate.
These reports are subject to potential revision by these manufacturers. If any
of our customers revised their product sales reports, we might be
 
                                       16
<PAGE>
 
required to restate our recognized revenues or adjust our revenues for
subsequent periods, which could harm our business and the price of our common
stock. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business--Sales and Marketing."
 
Our business is subject to risks from international operations
 
   We expect to derive an increasing amount of our revenue from sales outside
North America. We have limited experience in marketing and distributing our
products internationally. In addition, there are certain risks inherent in
doing business on an international basis, including, among others:
 
    .  legal uncertainty regarding liability;
 
    .  tariffs, trade barriers and other regulatory barriers;
 
    .  problems in collecting accounts receivable;
 
    .  political and economic instability;
 
    .  changes in diplomatic and trade relationships;
 
    .  seasonal reductions in business activity;
 
    .  potentially adverse tax consequences;
 
    .  the impact of recessions in economies outside the United States; and
 
    .  variance and unexpected changes in local laws and regulations.
 
   Our licensees are subject to many of the risks described above with respect
to their manufacturing or end-user customers. Currently, all of our
international sales are denominated in U.S. dollars; therefore, a strengthening
of the dollar could make our products less competitive in foreign markets. We
do not use derivative instruments to hedge foreign exchange risk. In the
future, we may conduct sales in local currencies, in which case, changes in
exchange rates could adversely affect our operating results. In addition, if we
conduct sales in local currencies, we may engage in hedging activities, which
may not be successful and could expose us to additional risks. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Qualitative and Quantitative Disclosures About Market Risk."
 
We may not be able to raise needed capital in the future
 
   We may require substantial additional capital to finance our future growth
and fund our ongoing research and development activities beyond 1999. Our
capital requirements will depend on many factors, including:
 
    .  acceptance of and demand for our products;
 
    .  the number and timing of acquisitions;
 
    .  the costs of developing new products;
 
    .  the costs associated with our expansion; and
 
    .  the extent to which we invest in new technology and research and
       development projects.
 
   To the extent that the proceeds of this offering, our existing sources of
cash and cash flow from operations, if any, are insufficient to fund our
activities, we may need to raise additional funds. If we issue additional stock
to raise capital, your percentage ownership in Divicore would be reduced.
Further, such additional stock may have rights, preferences or privileges
senior to those you possess as a holder of our common stock. Additional
financing may not be available when needed and, if such financing is available,
it may not be available on terms favorable to us. See "Management's Discussion
and Analysis of Financial Condition and Results of Operation--Liquidity and
Capital Resources."
 
 
                                       17
<PAGE>
 
The name of our business is changing and the market and potential customers may
not recognize our new name for some time
 
   We are in the process of changing our name from Quadrant International, Inc.
to Divicore Inc. It is likely that for a period of time after this change
occurs, potential customers and the market in general may not recognize our new
name. If potential customers do not realize who we are, we may lose future
business to competitors, which would harm our business.
 
Our officers and directors will be able to exert significant control over our
future direction
 
   Executive officers, directors and entities affiliated with them will, in the
aggregate, beneficially own approximately    % of our outstanding common stock
following the completion of this offering. These stockholders, if acting
together, would be able to significantly influence all matters requiring
approval by our stockholders, including the election of directors and the
approval of mergers or other business combination transactions. See "Principal
Stockholders."
 
We have adopted certain anti-takeover provisions
 
   After this offering, the board of directors will have the authority to issue
up to 5,000,000 shares of preferred stock. Further, without any further vote or
action on the part of the stockholders, the board of directors will have the
authority to determine the price, rights, preferences, privileges and
restrictions of the preferred stock. This preferred stock, if it is ever
issued, may have preference over and harm the rights of the holders of common
stock. Although the issuance of this preferred stock will provide us with
flexibility in connection with possible acquisitions and other corporate
purposes, this issuance may make it more difficult for a third party to acquire
a majority of our outstanding voting stock. We currently have no plans to issue
preferred stock.
 
   Our certificate of incorporation and by-laws include provisions that may
have the effect of deterring an unsolicited offer to purchase Divicore. These
provisions, coupled with the provisions of the Delaware General Corporation
Law, may delay or impede a merger, tender offer or proxy contest involving
Divicore. Furthermore, upon reincorporation, our board of directors will be
divided into three classes, only one of which is elected each year. Directors
will only be capable of being removed by the affirmative vote of 66 2/3% or
greater of all classes of voting stock. These factors may further delay or
prevent a change of control of Divicore. See "Description of Capital Stock--
Antitakeover Effects of Provisions of the Certificate of Incorporation, By-laws
and Delaware Law."

                         Risks Related to our Industry
 
Our revenues are dependent upon increasing penetration of digital video
technologies in the personal computer and consumer electronics industries
 
   The personal computer and consumer electronics industries are presently the
principal markets for our digital video and audio solutions. As a result, our
results of operations will depend largely on consumer acceptance of the
products that incorporate our digital video technology. In particular, in the
near term, we are dependent on the success of DVD-related products. Our
dependence on these industries involves several risks and uncertainties,
including:
 
    .  the decision by personal computer and consumer electronics
       manufacturers to select our digital solutions for incorporation into
       their products;
 
    .  the developing and marketing of content by third party content
       providers for end user systems such as DVD players and desktop
       computers in a format compatible with our digital solutions;
 
    .  the sustaining and developing of the demand for DVD players or other
       existing applications;
 
    .  whether semiconductor manufacturers developing silicon devices for
       personal computer and consumer electronics manufacturers will design
       our digital solutions into their devices and successfully introduce
       these devices;
 
    .  the potential for declining demand for DVD solutions in lower price
       personal computers;
 
    .  changes in consumer requirements and preferences;
 
    .  the introduction of products by our competitors embodying new
       technologies or features;
 
    .  limited opportunities for design wins due to the small number of
       product manufacturers in these industries and the length of product
       life cycles;
 
    .  the difficulty in predicting the level of consumer interest in and
       acceptance of many digital product applications, such as handheld
       personal computers and set-top boxes, which have only recently been
       introduced to the market; and
 
    .  the current lack of open industry standards for software and
       hardware in the consumer electronics industry.
 
   Factors negatively affecting the consumer electronics or personal computer
industries could harm our business. Moreover, to the extent that the
performance, functionality, price and power characteristics of our digital
solutions fail to satisfy customers who have a critical need for specific
digital applications, the use of our digital solutions could become confined to
a limited segment of these industries. See "Business--Sales and Marketing" and
"--Strategy."
 
Our markets are highly competitive
 
   We compete in markets that are new, intensely competitive, highly fragmented
and rapidly changing and which are characterized by short product life cycles
and price erosion. Our competitors in the software-based digital solution
market include Mediamatics, Inc. (a subsidiary of National Semiconductor,
Inc.), Zoran Corporation and Xing Technology Corporation (which has agreed to
be acquired by RealNetworks, Inc.). Our competitors in the hardware-based
digital solution market include Sigma Designs, Inc. and several smaller
competitors. We also compete with the internal research and development
departments of other software companies as well as those of personal computer,
peripherals, consumer electronics and semiconductor manufacturers who are in
the market for specific digital video or audio software applications. Numerous
other major personal computer manufacturers, software developers and other
companies are focusing significant resources on developing and marketing
products and services that will compete with our CineMaster products. Some
semiconductor manufacturers are positioning their products as offering
hardware-based digital video and audio management capabilities and marketing
such products as equal or superior to our CineMaster products. In
 
                                       19
<PAGE>
 
the future, operating system providers with a larger established customer base,
such as Microsoft, may enter the digital video or audio stream management
markets by building video or audio stream management applications into their
operating systems. Personal computer and consumer electronics manufacturers may
use such products as their digital solutions.
 
   We anticipate continued growth and competition in the digital video industry
and the entrance of new competitors into our markets, and that, accordingly,
the market for our products will remain intensely competitive. We expect that
competition will increase in the near term and that our primary long-term
competitors may not yet have entered the market. Our future competitors may
have significantly more personnel or greater financial, technical, marketing
and other resources than either we or our current competitors do. Furthermore,
our future competitors may be able to respond more quickly to new or emerging
technologies and changes in customer requirements than we can. Also, future
competitors may have greater name recognition and more extensive customer bases
that they can leverage. Increased competition could result in price reductions,
fewer customer orders, reduced gross profit margins and loss of market share,
any of which could harm our business. See "Business--Competition."
 
We must manage technological change, respond to evolving industry standards and
enhance our products' interoperability with the products of our customers
 
   Future versions of software and hardware platforms embodying new
technologies or the emergence of new industry standards could render our
products and services obsolete or uncompetitive. The market for digital video
and audio stream management hardware and software is characterized by rapid
technological change, frequent new product introductions, changes in customer
requirements and evolving industry standards. Since the digital video and audio
market is still evolving, only a limited number of commercial and consumer
products incorporating our digital solutions are currently in volume
production. Our results of operations will depend upon our ability to develop
and introduce a variety of new products and product enhancements to address the
increasingly sophisticated needs of our customers.
 
   Our results of operations will depend on the extent to which our CineMaster
products are incorporated into the products of leading personal computer,
consumer electronics, peripherals and semiconductor manufacturers. Their
willingness to incorporate our products depends upon whether we succeed in
developing enhancements and new generations of our software and hardware that
satisfy the requirements of specific system or program applications and
introduce these new technologies to the marketplace in a timely manner. We must
constantly modify or improve our products to keep pace with changes made to
these platforms and other systems. If we fail to modify or improve our products
in response to evolving industry standards, our products could rapidly become
obsolete, which would harm our business. If the characteristics of our digital
solutions are not compatible with the requirements of specific system or
program applications, the likelihood that our customers will design our
products into their systems and devices will decrease and our business will be
harmed.
 
   Technical innovations in our markets involve several risks, including:
 
    .  our ability to anticipate and timely respond to changes in the
       requirements of consumer electronics and personal computer
       manufacturers;
 
    .  changing consumer preferences in the consumer electronics and
       personal computer markets;
 
    .  the introduction by our competitors of products embodying popular
       new technologies or features;
 
    .  the emergence of new standards in digital video and audio stream
       management within the consumer electronics and personal computer
       industries; and
 
    .  the significant investment that is often required before commercial
       viability is determined.
 
   Any failure by us to adequately address these risks could render our
existing digital solutions obsolete and could harm our business. In addition,
we may not have the financial and other resources necessary to develop digital
solutions in the future, or develop any enhancements or new generations of the
technology that generate revenue in excess of the costs of development. See
"Business--Research and Development."
 
                                       20

Year 2000 issues present technological risks to our business and could harm
sales
 
   In order to save valuable memory, many existing computer systems and
software programs were designed to calculate or refer to the year in any
calendar date using the last two digits and presuming that the first two digits
are "19." As a result, these systems and programs may not be able to
distinguish whether "00" means 1900 or 2000. This may result in software
failures or the creation of erroneous results known as Year 2000 failures. If
the systems or programs look ahead of the current date for any reason, they may
need to refer to dates occurring after December 31, 1999. As a result, Year
2000 failures may occur at any time, including prior to January 1, 2000.
 
   Neither our Hardware CineMaster nor our Software CineMaster products make
use of calendar clocks in any way. However, our products are incorporated into
software and hardware of personal computer, consumer electronics, computer
peripheral and semiconductor manufacturers, some of which may make use of
calendar clocks and may therefore experience Year 2000 failures. We have
recently initiated a comprehensive assessment of the possibility of Year 2000
failures affecting us and we have replaced our internal computer systems and
application software as a precaution. However, we cannot assure you that third-
party software and hardware that is incorporated into our information systems
will not need to be revised or replaced as well. If we were required to replace
these third-party products, our business could be harmed. In addition, we have
performed operational tests on our products as incorporated into those of our
customers and these tests have not resulted in Year 2000 failures. Nonetheless,
these tests may not be completely accurate and Year 2000 failures may occur. If
our customers' hardware or software were to suffer Year 2000 failures, such
failures might cause our CineMaster products to fail as well. Changes required
to respond to Year 2000 failures caused by interoperability issues could be
expensive and time consuming and lead to lost revenues, breach of contract
claims, higher operating costs, loss of customers and other business
interruptions, any of which could harm our business.
 
   In addition, governmental agencies, utility companies, Internet access
companies, third-party service providers and others outside of Divicore's
control may suffer Year 2000 failures. If these entities were to suffer Year
2000 failures, a systemic failure might occur which is beyond our control, such
as a prolonged Internet, telecommunications or electrical failure. A systemic
failure could prevent us from delivering our services to our customers or cause
other business disruptions, such as preventing our customers or potential
customers from accessing our Internet web site. Any significant disruption in
the infrastructure on which we rely could harm our business. See "Management's
Discussion and Analysis of Financial Conditions and Results of Operations--Year
2000 Compliance."
 
We face risks from the uncertainties of governmental regulation
 
   We are not currently subject to direct regulation by any domestic or foreign
governmental agency, other than regulations applicable to businesses generally.
However, due to the increasing popularity and use of the digital delivery
mediums, it is possible that future laws and regulations may be adopted that
regulate DSS/DBS or other markets in which our products are sold. Such
regulatory measures may include, among other things:
 
    .  pricing;
 
    .  content;
 
    .  copyrights;
 
    .  export controls (particularly regarding data encryption);
 
    .  distribution; and
 
    .  characteristics and quality of products and services.
 
   The growth and development of the digital media market may prompt calls for
more stringent consumer protection laws that may impose additional burdens on
those companies conducting business in this segment. The adoption of any
additional laws or regulations may decrease the expansion of this market and
harm our
 
                                       21
<PAGE>
 
business. Our business could be harmed by any new legislation or regulation,
the application of laws and regulations from jurisdictions whose laws do not
currently apply to our business, or the application of existing laws and
regulations to the digital media market.
 
                         Risks Related to this Offering
 
We have substantial discretion as to how to use the proceeds from this offering
 
   We expect to use the net proceeds of this offering primarily for working
capital and other general corporate purposes. In particular, we intend to
increase our spending on marketing, research and development and product
management. We may also use some of the proceeds to acquire other businesses,
products or technology which would complement our existing products, expand our
market coverage or enhance our technological capabilities. We have no specific
plan as to how we will spend the proceeds of this offering. As a result, our
management will have discretion over how to use all of the funds provided by
this offering. If our management uses poor judgment in spending the proceeds,
our business will be adversely affected. We cannot assure you that investment
of the proceeds will yield a favorable return or any return. See "Use of
Proceeds."
 
There has been no prior public market for our common stock, and the price of
our common stock may be volatile
 
   Our common stock has never been sold in a public market. An active trading
market for our common stock may not develop in the future. If an active trading
market does develop, it may not last. Moreover, if an active market does
develop, the trading price of the shares being sold in this offering may
fluctuate widely as a result of a number of factors, most of which are outside
our control. Some of these factors include:
 
    .  quarter-to-quarter variations in our operating results;
 
    .  our announcements about the performance of our products and our
       competitors' announcements about performance of their products;
 
    .  changes in earnings estimates by, or failure to meet the
       expectations of, analysts;
 
    .  government regulatory action;
 
    .  increased price competition;
 
    .  developments or disputes concerning intellectual property rights;
       and
 
    .  general conditions in the computer industry.
 
   In addition, the stock market has experienced extreme price and volume
fluctuations, which have particularly affected the market prices of many
technology and computer software companies and which have often been unrelated
to the operating performance of these companies.
 
   We are negotiating the initial offering price of the common stock with the
underwriters. However, the initial offering price may not be indicative of the
prices that will prevail in the public market after the offering, and the
market price of the common stock could fall below the initial public offering
price. See "Underwriting."
 
Our stock price may be affected by shares eligible for future sale
 
   If our stockholders sell substantial amounts of our common stock in the
public market following this offering, including shares issued upon the
exercise of outstanding options and warrants, the trading price of our common
stock could fall. Such sales also might make it more difficult for us to sell
equity or equity-related securities in the future at a time and price that we
deem appropriate. Upon completion of this offering, we will
 
                                       22
<PAGE>
 
have outstanding             shares of common stock (based upon shares
outstanding as of March 31, 1999), assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options or warrants after
March 31, 1999. Of these shares, the          shares sold in this offering will
be freely tradable. This leaves            shares eligible for sale in the
public market 180 days from the date of this prospectus, substantially all of
which are subject to lock up agreements. Bear, Stearns & Co. Inc. may, in its
sole discretion and at any time without notice, release all or any portion of
the securities subject to lock-up agreements.
 
   After this offering, if certain conditions are met, the holders of
approximately 5,961,046 shares of common stock and the holders of warrants to
purchase up to approximately 1,608,172 shares of common stock will be entitled
to require us to register their shares under the Securities Act. These
shareholders also have the right to participate in any registration of our
shares which we undertake on our own. If these shareholders exercise their
registration rights, a large number of our shares may be registered and sold in
the public market. This could adversely affect the trading price for our
shares. If we attempted to raise money through a registration and sale of our
stock and these shareholders forced us to allow them to participate in the
registration, our ability to raise the amount of money we need to execute our
business plan could be adversely affected. See "Description of Capital Stock--
Registration Rights."
 
You will experience substantial dilution in the value of your shares
immediately following this offering
 
   The price of the shares is substantially higher than the net tangible book
value per share. If you buy any shares in the offering, you will incur
immediate and substantial dilution in the pro forma net tangible book value of
each share. If others exercise options to purchase our common stock, you will
suffer further dilution. See "Dilution."

                                USE OF PROCEEDS
 
   The net proceeds to Divicore from the sale and issuance of the      shares
of common stock offered hereby are estimated to be $    million (approximately
$    million if the underwriters' over-allotment option is exercised in full),
at the assumed initial public offering price of $    per share after deducting
the underwriting discount and estimated offering expenses. Divicore is
conducting this offering primarily to increase its equity capital, create a
public market for its common stock and to facilitate future access by Divicore
to public equity markets. Divicore intends to use the net proceeds for general
corporate purposes, including working capital, product development and capital
expenditures. In addition, Divicore may use a portion of the net proceeds to
acquire or invest in complementary businesses or products or to obtain the
right to use complementary technologies. Divicore has no commitments with
respect to any acquisition or investment, and it is not involved in any
negotiations with respect to any similar transaction. Pending these uses, the
net proceeds of this offering will be invested in short-term, interest-bearing,
investment grade securities.
 
                                DIVIDEND POLICY
 
   Divicore has never declared or paid dividends on its capital stock and does
not anticipate declaring or paying cash dividends in the foreseeable future.
Divicore anticipates that it will retain all future earnings, if any, for use
in its operations and the expansion of its business. Payments of future
dividends, if any, will be at the discretion of Divicore's board of directors
after taking into account various factors, including its financial condition,
operating results, current and anticipated cash needs and plans for expansion.
Moreover, pursuant to agreements with its lender, Divicore is prohibited from
declaring or paying dividends without the prior written consent of the lender.

                                    DILUTION
 
   Dilution is the amount by which the initial public offering price paid by
the purchasers of shares of common stock in the offering exceeds the net
tangible book value per share of common stock after the offering. The pro forma
net tangible book value per share of common stock is determined by subtracting
Divicore's total liabilities from the total book value of its tangible assets
and dividing the difference by the number of shares of common stock deemed to
be outstanding on the date as of which such book value is determined.
 
   The pro forma net tangible book value of Divicore at March 31, 1999, was
approximately $3,780,000, or $0.36 per share. After giving effect to the sale
of the shares of common stock offered by Divicore at the assumed initial public
offering price of $       per share, and after deducting underwriting discounts
and estimated offering expenses, Divicore's pro forma net tangible book value
at March 31, 1999, would have been $         , or $      per share. This
represents an immediate increase in net tangible book value of $        per
share to existing stockholders and an immediate dilution of $        per share
to new investors purchasing shares of common stock in this offering. The
following table illustrates this dilution:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   The following discussion of the financial condition and results of
operations of Divicore should be read in conjunction with the consolidated
financial statements and notes thereto and the unaudited pro forma financial
statements included elsewhere in this prospectus. This discussion contains
forward-looking statements that involve risks and uncertainties. Divicore's
actual results could differ from those anticipated in these forward-looking
statements as a result of various factors including but not limited to, those
discussed in "Risk Factors," "Business" and elsewhere in this prospectus.
 
Overview
 
   Divicore designs, develops, licenses and markets innovative core-based
modular software solutions that enable digital video and audio stream
management in personal computer systems and consumer electronics devices.
Divicore also licenses supporting hardware designs to selected customers and
provides customization services and customer support. Divicore's solutions
enable decoding and encoding multimedia formats such as DVD, DBS/DVB and HDTV
on existing personal computer and consumer electronics platforms. Divicore's
digital solutions incorporate industry standards for video and audio
compression and are independent of operating systems and silicon components.
 
   Divicore's customers consist primarily of personal computer and consumer
electronics manufacturers. In addition, Divicore supplies its software
solutions and hardware designs to selected peripherals providers and
semiconductor manufacturers. In 1998 and the first quarter of 1999, Divicore
generated substantially all of its total revenues, respectively, from personal
computer and peripherals manufacturers. However, Divicore anticipates that an
increasing percentage of revenues, beginning in the second half of 1999, will
be derived from consumer electronics and semiconductor manufacturers.
 
   Prior to 1998, Divicore generated revenue primarily from direct sales of its
hardware solutions to retail distributors and end users. In 1998, substantially
all of Divicore's revenues were derived from Software CineMaster 98 and
Hardware CineMaster 98. Divicore introduced the first in its line of digital
video products in March 1997 with the launch of CineMaster, a hardware and
software solution sold to personal computer manufacturers, which enabled DVD
playback on a personal computer. In December 1997, Divicore introduced its
second generation hardware and software solution called Hardware CineMaster 98.
In August 1998, Divicore launched its software-only solution, Software
CineMaster 98, and began to transition its business model from a direct product
sales approach to a license approach. As part of its license approach, in
February 1999, Divicore began entering into manufacturing and license
agreements with third parties under which Divicore will no longer manufacture
Hardware CineMaster 98. Instead, Divicore will receive a per unit license fee
on all future sales of Hardware CineMaster 98. Divicore is currently in the
process of completing its transition to a license model and, in the future,
Divicore expects that most of its revenues will be derived from licenses of its
software and its hardware designs. As a result of this change, Divicore will
recognize lower revenues in 1999 than in 1998, which Divicore expects to be
accompanied by a decrease in its cost of revenues.
 
   Divicore's revenues are comprised of hardware revenues, license revenues and
services revenues. Hardware revenues, consisting of direct sales of hardware
subsystems to personal computer and peripherals manufacturers, have represented
most of Divicore's total revenues in the past but are expected to be nominal in
the future. License revenues consist of fees paid on a per unit basis, or in
certain cases in advance, each time a manufacturer ships a product that
incorporates Divicore's software solutions or software with supporting hardware
designs. License revenues are charged either as a percentage of the revenue
received by the seller on sales of the products or on a per unit basis. Service
revenues consist of engineering fees from consumer electronics, personal
computer, peripherals and semiconductor manufacturers for custom engineering
services. Services are generally billed on either a time and material basis or
on a project or contract basis.
 
                                       31

   License revenues are recognized when earned, which is generally based on
receiving notification from a licensee detailing the shipments of products
incorporating Divicore technology. In a number of cases, this occurs in the
quarter following the sale of the licensee's product to its customers.
Divicore's license agreements generally have a term of one year or more, and
typically require payment within 45 days after the end of the calendar quarter
in which the product is shipped. Some of Divicore's contracts may also require
payment of an up-front license fee. License fees paid in advance, with no
further future commitment, are recognized in the period received. The amount
and timing of prepaid fees could cause Divicore's operating results to vary
significantly from period to period. Services revenues are recognized upon
delivery of the service in the case of time and material contracts or on a
percentage completion basis in the case of project-based contracts. Hardware
product sales are recognized upon shipment of the product to the manufacturer
or end user.
 
   Divicore's revenues are concentrated among a few customers. In 1998, Dell
Computer accounted for approximately 81% of total revenues and 40% of gross
profit. ATI Technologies accounted for approximately 6% of total revenues and
27% of gross profit. Revenues from ATI Technologies made a relatively larger
contribution to gross profit because revenues from ATI Technologies consisted
entirely of license fees. In the three months ended March 31, 1999, Dell
Computer, ATI Technologies and Gateway accounted for 73%, 6% and 10% of
Divicore's revenues and 34%, 20% and 24% of its gross profit, respectively.
While Divicore believes that the number of customers incorporating its
technology into their products will grow, Divicore expects that a significant
portion of revenue will continue to be concentrated among a relatively small
number of customers for the foreseeable future. The revenues from particular
customers may vary widely from period to period depending on the addition of
new contracts and the volumes and prices at which licensees sell Divicore-
enabled products to end users in any given period.
 
   Divicore sells its products directly to personal computer and consumer
electronics manufacturers in the United States and Europe and through a sales
representative in Japan. To date, companies based in the Pacific Rim and Europe
have accounted for a small portion of Divicore's revenues. Sales outside of the
United States have been primarily through U.S. manufacturers that distribute
their products to end users overseas.
 
   In April 1998, Divicore acquired Viona, a German engineering services
company. Prior to the acquisition, Divicore had contracted Viona to co-develop
its products and a significant portion of its software and systems
architecture. The purchase price was approximately $11.4 million, and the
acquisition was recorded under the purchase method of accounting. The results
of operations of Viona have been included in Divicore's operating results since
the date of acquisition. In connection with the acquisition, Divicore expensed
$7.9 million of the Purchase Price as acquired in-process research and
development. Divicore plans to amortize the remaining goodwill and other
intangibles associated with the acquisition over the next four years. See "--
Acquired In-Process Research and Development" and Note 4 of the notes to
consolidated financial statements.
 
   In April 1999, Divicore completed a financing in which it issued convertible
securities to Intel of $4.7 million and entered into a license agreement
covering certain Intel technology.
 
   Divicore's future net income and cash flow will also be affected by its
ability to apply its net operating losses, which totaled approximately $14.1
million for federal tax reporting purposes as of March 31, 1999, against
taxable income in future periods. Due to the uncertainty of Divicore's ability
to realize the benefit of the deferred tax assets, the deferred tax assets are
fully offset by a valuation allowance. Under the Tax Reform Act of 1986, the
use of net operating losses may be impaired or limited in certain
circumstances, including a cumulative ownership change of greater than 50% over
a three-year period. The consummation of this offering, together with previous
equity transactions, will most likely result in a cumulative ownership change
of greater than 50%. Accordingly, Divicore's net operating losses incurred
prior to this offering that can be used to reduce future taxable income for
federal tax purposes will most likely be limited. Future changes of ownership,
including this offering, could further limit Divicore's use of net operating
losses and could have an adverse effect on its net income and cash flow.
Changes in tax laws in the United States or in our status may limit Divicore's
ability to use its net operating losses. Any limitation on Divicore's ability
to use its net operating losses could harm its business. See Note 15 of the
notes to consolidated financial statements.

Three Months Ended March 31, 1998 and 1999
 
   Revenues. Total revenues increased 244% from $3.1 million for the quarter
ended March 31, 1998 to $10.8 million for the quarter ended March 31, 1999.
License revenues increased to $2.0 million for the quarter ended March 31,
1999, due primarily to growth in license fees associated with Divicore's
Software CineMaster 98 product. Services revenues increased from $0.01 million
to $0.3 million for the quarter ended March 31, 1999, representing primarily
increased customization services related to Divicore's consumer electronics
business. Hardware revenues increased 172% from $3.1 million for the quarter
ended March 31, 1998 to $8.5 million for the quarter ended March 31, 1999, due
primarily to increased market acceptance of Divicore's Hardware Cinemaster 98
product.
 
   Cost of Revenues. Cost of revenues consist primarily of manufacturing costs
associated with Divicore's hardware solution, costs associated with shipment of
Divicore's software solution and license fees paid to third parties for
technologies incorporated into Divicore's products, including Dolby Digital
technology. Cost of revenues increased 140% from $3.1 million for the quarter
ended March 31, 1998 to $7.4 million for the quarter ended March 31, 1999. The
increase in cost of revenues was primarily due to increased product costs
associated with the manufacturing of Divicore's hardware related products and
increased sublicense fees associated with the licensing of third party
technology.
 
   Gross Profit. Gross profit increased from $0.07 million for the quarter
ended March 31, 1998 to $3.4 million for the quarter ended March 31, 1999,
primarily due to increased revenues. As a percentage of total revenues, gross
profit increased from 2% for the quarter ended March 31, 1998 to 32% for the
quarter ended March 31, 1999, primarily as a result of a higher proportion of
license revenues associated with Divicore's transition during this quarter to a
business model based on licensing its technology rather than direct sales of
hardware products.
 
                                       33

   Research and Development Expenses. Research and development expenses consist
primarily of engineering and related costs associated with the development of
new products, customization of existing products for customers, quality
assurance and testing. Research and development expenses increased 194%, from
$0.5 million for the quarter ended March 31, 1998 to $1.5 million for the
quarter ended March 31, 1999. As a percentage of total revenues, research and
development expenses decreased from 16% to 14%. The increase in research and
development expenses in absolute dollars was due primarily to supporting an
expanded customer base and additional new products. The decrease in research
and development expenses as a percentage of total revenues resulted primarily
from Divicore's increased revenue base. Divicore expects research and
development expenses to continue to increase in absolute dollars in 1999
compared to 1998 as Divicore adds additional engineering staff and
capabilities.
 
   Sales and Marketing Expenses. Sales and marketing expenses consist primarily
of salaries, travel expenses and costs associated with trade shows, advertising
and other marketing efforts, as well as technical support costs. Sales and
marketing expenses increased 128% from $0.5 million for the quarter ended March
31, 1998 to $1.1 million for the quarter ended March 31, 1999. As a percentage
of total revenues, sales and marketing expenses decreased from 15% to 10%. The
increase in absolute dollars was primarily due to the building of the sales and
marketing teams in the United States and the increased emphasis on enhancing
market awareness. The decrease in sales and marketing expenses as a percentage
of total revenues resulted primarily from Divicore's increased revenue base.
Divicore expects sales and marketing expenses to increase in absolute dollars
in 1999 compared to 1998.
 
   General and Administrative Expenses. General and administrative expenses
consist primarily of personnel and support costs for Divicore's finance, human
resources, information systems and other management departments. General and
administrative expenses increased 66% from $0.5 million for the quarter ended
March 31, 1998 to $0.8 million for the quarter ended March 31, 1999. As a
percentage of total revenues, general and administrative expenses decreased
from 16% to 8%. The increase in absolute dollars was primarily due to
expenditures on administrative infrastructure to support Divicore's growing
business operations. General and administrative expenses decreased as a
percentage of total revenues primarily due to Divicore's increased revenue
base. Divicore expects general and administrative expenses to increase in
absolute dollars in 1999 compared to 1998 as it continues to build the
necessary infrastructure to support its business operations and incurs greater
legal and accounting expenses as a public company.
 
   Deferred Stock Compensation. In September 1998 and February 1999, Divicore
recorded $0.8 million and $0.5 million, respectively, of deferred stock
compensation in connection with grants of stock options. Divicore will amortize
this amount as compensation expense over the four year vesting period of the
options which will approximate $0.08 million per quarter.
 
   Depreciation and Amortization Expense. Divicore recorded depreciation and
amortization expense of $0.3 million for the quarter ended March 31, 1999
primarily related to the goodwill recorded as part of the Viona acquisition.
See "--Acquired In-Process Research and Development Expense."
 
Years Ended December 31, 1997 and 1998
 
   Revenues. Total revenues increased 344% from $6.8 million in 1997 to $30.3
million in 1998. License revenues increased 107% from $1.3 million in 1997 to
$2.8 million in 1998, primarily due to Divicore's launch of its first software
solution. Services revenues increased 515% from $0.1 million in 1997 to $0.7
million in 1998, primarily due to the completion of one large engineering
services contract in 1997. Hardware revenues increased 399% from $5.4 million
in 1997 to $26.8 million in 1998, primarily due to increased market acceptance
of Divicore's products, and significant sales to Dell Computer which
incorporated Divicore's solution into a particular line of personal computers.
 
   Cost of Revenues. Cost of revenues increased 192%, from $8.4 million in 1997
to $24.5 million in 1998. The increase in cost of revenues was primarily due to
increased product costs associated with the manufacturing of Divicore's
hardware related products and increased sublicense fees associated with the
license of third party technology.

   Gross Profit. Gross profit increased from a negative $1.6 million in 1997 to
$5.7 million in 1998. As a percentage of total revenues, gross profit increased
from a negative 23% to 19% in 1998. The increase in gross profit both in
absolute dollars and as a percentage of total revenues was primarily due to
growth in Divicore's software and license business and the growth in sales of
hardware subsystems.
 
   Research and Development Expenses. Research and development expenses
increased 71% from $1.8 million in 1997 to $3.1 million in 1998. As a
percentage of total revenues, research and development expenses decreased from
27% in 1997 to 10% in 1998. The increase in research and development expenses
in absolute dollars was due primarily to increased headcount associated with
customer delivery, new product development and advanced research and
development. The decrease in research and development expenses as a percentage
of total revenues resulted primarily from Divicore's increased revenue base.
 
   Sales and Marketing Expenses. Sales and marketing expenses increased 70%
from $1.2 million in 1997 to $2.0 million in 1998. As a percentage of total
revenues, sales and marketing expenses decreased from 17% to 6%. The increase
in absolute dollars was primarily due to the building of the sales and
marketing teams in the United States and the increased emphasis on enhancing
market awareness. The decrease in sales and marketing expenses as a percentage
of total revenues resulted primarily from Divicore's shift from a retail-
oriented distribution model which required greater advertising expenses and
from Divicore's increased revenue base.
 
   General and Administrative Expenses. General and administrative expenses
increased 173% from $1.7 million in 1997 to $4.7 million in 1998. As a
percentage of total revenues, general and administrative expenses decreased
from 25% to 15%. The increase in absolute dollars was primarily due to
expenditures on administrative infrastructure to support Divicore's growing
business operations. The decrease in general and administrative expenses as a
percentage of total revenues was primarily due to Divicore's increased revenue
base.
 
   Depreciation and Amortization Expense. Divicore recorded depreciation and
amortization expense in 1998 of $0.9 million primarily related to the goodwill
recorded as part of the Viona acquisition. Additionally Divicore wrote off $7.9
million of acquired in-process research and development. See "--Acquired In-
Process Research and Development."
 
Years Ended December 31, 1996 and 1997
 
   Revenues. Total revenues increased 63% from $4.2 million in 1996 to $6.8
million in 1997. License revenues increased 299% from $0.3 million in 1996 to
$1.3 million in 1997. The increase in license revenues was primarily due to the
addition of a large licensing customer. Services revenues decreased from
$0.5 million in 1996 to $0.1 million in 1997. Hardware revenues increased 60%
from $3.4 million in 1996 to $5.4 million in 1997. The increase in hardware
revenues was primarily due to increased market acceptance of Divicore's
software solutions with supporting hardware platform designs.
 
   Cost of Revenues. Cost of revenues increased 168% from $3.1 million in 1996
to $8.4 million in 1997. The increase in cost of revenues was primarily due to
increased product costs associated with the manufacturing of Divicore's
hardware related products.
 
   Gross Profit. Gross profit decreased from $1.1 million in 1996 to a negative
$1.6 million in 1997. The decrease in gross profit both in absolute dollars and
as a percentage of total revenues was primarily due to the expenses associated
with obsolete inventory and price protection.
 
   Research and Development Expenses. Research and development expenses
increased 77% from $1.0 million in 1996 to $1.8 million in 1997. As a
percentage of total revenues, research and development expenses increased from
25% in 1996 to 27% in 1997. The increase in research and development expenses
in absolute dollars and as a percentage of total revenues was due primarily to
increased headcount associated with customer delivery, new product development
and advanced research and development.
 
   Sales and Marketing Expenses. Sales and marketing expenses increased from
$0.7 million in 1996 to $1.2 million in 1997. As a percentage of total
revenues, sales and marketing expenses remained constant at 17% in 1996 and
1997.

   General and Administrative Expenses. General and administrative expenses
increased 43% from $1.2 million in 1996 to $1.7 million in 1997. As a
percentage of total revenues, general and administrative expenses decreased
from 29% to 25%. The increase in absolute dollars was primarily due to
expenditures on administrative infrastructure to support Divicore's growing
business operations. The decrease in general and administrative expenses as a
percentage of total revenues was primarily due to Divicore's increased revenue
base.

   Hardware revenues decreased in the quarters ending September 30, 1997 and
December 31, 1997 from prior periods due to Divicore's transition away from
distributors and retail customers towards top tier personal computer
manufacturer customers. License revenues increased $1.3 million in the quarter
ending March 31, 1999 from the immediately preceding quarter due to the
Company's transition towards a licensing model. License revenues increased $0.4
million in the quarter ending September 30, 1998 primarily due to revenues from
a large up-front license fee. Hardware revenues decreased $3.2 million in the
quarter ending March 31, 1999 from the immediately preceding quarter primarily
due to Divicore's transition away from a hardware sales model towards a
licensing model. Cost of revenues increased $1.0 million in the quarter ending
December 31, 1997 from the immediately preceding quarter due to the write-off
of inventory and price protection associated with Divicore's transition away
from the retail distribution channel. Gross profit decreased by $0.3 million in
the quarter ending December 31, 1998 from the immediately preceding quarter.
The decline, both in absolute dollars and as a percentage of revenues, was
primarily due to large upfront license fees received in the preceding quarter.
In April 1998, Divicore expensed $7.9 million of the purchase price as acquired
in-process research and development in connection with the acquisition of
Viona. The increases in general and administrative expense beginning in the
quarter ending June 30, 1998 are primarily the result of increased personnel,
higher facility costs and professional fees to support the growth of Divicore's
infrastructure. General and administrative expenses declined by $0.8 million
for the quarter ended March 31, 1999 as compared to the immediately preceding
quarter primarily due to reclassification of overhead costs in order to more
accurately reflect departmental reporting and one time fees for professional
services. The increase in depreciation and amortization expense beginning in
the quarter ending June 30, 1998 is the result of the amortization of goodwill
and other intangible assets in connection with the acquisition of Viona in
April 1998. Compensation expense related to stock options in the quarters
ending September 30, 1997 and December 31, 1998 relates to stock options
granted to certain employees of Divicore at less than the estimated fair market
value of Divicore's common stock on the date of grant.
 
   Divicore's business is subject to a variety of risks, including but not
limited to: variations in demand for Divicore's products; the timing of sales
of Divicore's products and the timing of releases of new personal computer
systems, consumer electronics devices and semiconductors that incorporate
Divicore's products; delays in introducing new products; changes in Divicore's
pricing policies or the pricing policies of Divicore's competitors; the timing
and accuracy of royalty reports received from Divicore's customers and the
execution of individual contracts, particularly large contracts that materially
affect Divicore's operating results in a given quarter; changes in the usage of
digital media; Divicore's ability to develop and attain market acceptance of
enhancements to Divicore's CineMaster products; new product introductions by
competitors; the mix of license, services and hardware revenues; the mix of
domestic and international sales; costs related to acquisitions of technologies
or businesses; Divicore's ability to attract, integrate, train, retain and
motivate a substantial number of sales and marketing, research and development,
administrative and product management personnel; Divicore's ability to expand
its operations; and global economic conditions as well as those specific to
personal computer, consumer electronics, peripherals and semiconductor
manufacturers and other providers of digital video and audio stream management
solutions. If any of these risks were to materialize, Divicore's quarterly and
annually operating results could be materially adversely affected.
 
Acquired In-Process Research and Development
 
   In April 1998, Divicore completed the acquisition of Viona, a company
specializing in the development of digital video technology. Divicore paid $6.1
million in cash, of which $2.6 million was paid at closing, $2.1 million will
be paid during 1999, and $1.4 million will be paid in equal installments at the
end of each of the next three fiscal years, issued 1,204,820 shares of
Divicore's common stock valued at $4.8 million and incurred transaction costs
of $0.8 million. For accounting purposes, payments due in future periods have
been discounted.
 
   The acquisition of Viona was recorded under the purchase method of
accounting. A portion of the purchase price was allocated to in-process
research and development technology, which resulted in a charge of
approximately $7.9 million to Divicore's operations in April 1998. The in-
process research and development
 
                                       37
<PAGE>
 
technology was valued using a cash flow model, under which projected income and
expenses attributable to the purchased technology were identified, and
potential income streams were discounted using a 30%-35% discount rate for
risks, probabilities and uncertainties, including the stage of development of
the technology, viability of target markets and other factors.
 
   As of the acquisition date, Viona was conducting significant ongoing
research and development into five new software and hardware products including
enhancements to the existing digital video and audio system solutions
previously developed by Divicore. At the date of acquisition, these projects
had not reached technological feasibility and there was no alternative future
use for them. The five research and development projects included:
 
    .  CineMaster LC Hardware DVD Decoder, a single circuit board or card
       that can be added to a personal computer to allow the personal
       computer to process digital video signals. At the time of the
       acquisition, Viona was conducting research and development to
       integrate this product into a single chip-based design in an effort
       to reduce manufacturing costs and to improve playback performance
       quality. This research and development project had completed only
       alpha testing and was approximately 80% complete at the date of
       acquisition. Viona had incurred approximately $117,000 of research
       and development expense and estimated that $35,000 would be required
       to complete the development of the project. Development was
       completed during 1998.
 
    .  CE DVD Set-top Player/Portable Player, a DVD playback set-top
       reference design for equipment manufacturers which was expected to
       provide full DVD playback capabilities such as fast forward,
       rewinding, multi-language and surround sound audio. At the time of
       the acquisition, this project had not yet completed alpha testing
       and there was significant uncertainty of completion. Divicore
       estimated that the project was approximately 5% complete. Viona had
       incurred approximately $30,000 of research and development expense
       and estimated that $500,000 would be required to complete the
       development of the project. Development is expected to be completed
       within the next twelve months.
 
    .  DVD Software Encoder, a software solution to enable the processing
       of digital video signals which is designed to eliminate the need for
       a DVD encoder chip or circuit board by utilizing software to record
       DVD and video streams on a personal computer. At the time of the
       acquisition, this project had not yet completed alpha testing and
       there was significant uncertainty of completion. Divicore estimated
       that the project was approximately 40% complete. Viona had incurred
       approximately $121,000 of research and development expense and
       estimated that $203,000 would be required to complete the
       development of the project. Development is expected to be completed
       within the next twelve months.
 
    .  HDTV Hardware Decoder, a circuit board or card that could enable
       personal computers to process HDTV signals. At the time of the
       acquisition, this project had not yet completed alpha testing and
       there was significant uncertainty of completion. Divicore estimated
       that the project was approximately 35% complete. Viona had incurred
       approximately $63,000 of research and development expense and
       estimated that $111,000 would be required to complete the
       development of the project. Development is expected to be completed
       within the next twelve months.
 
    .  HDTV Software Decoder, a software solution designed to allow a
       personal computer to process HDTV signals without the need for a
       hardware solution. At the time of the acquisition, this project had
       not yet completed alpha testing and there was significant
       uncertainty of completion. Divicore estimated that the project was
       approximately 15% complete. Viona had incurred approximately $15,000
       of research and development expense and estimated that $150,000
       would be required to complete the development of the project.
       Development is expected to be completed within the next twelve
       months.

   The efforts required to develop the acquired in-process technology into
commercially viable products principally relate to the completion of all
planning, designing and testing activities that are necessary to establish that
the products can meet their design requirements, including function, features
and technical performance requirements.
 
   Divicore based its determination of the acquired in-process technology
allocation on recently issued guidance by the Securities and Exchange
Commission and considered such factors as degree of completion, technological
uncertainties, costs incurred and projected costs to complete. Acquired in-
process technology projects continue to progress, in all material respects,
consistent with management's original assumptions used to value the acquired
in-process technology. See Note 4 of Notes to Consolidated Financial
Statements.
 
Liquidity and Capital Resources
 
   Since inception, Divicore has financed its operations primarily through the
issuance and sale of debt and equity securities to investors. As of March 31,
1999 Divicore had approximately $2.2 million in cash and cash equivalents.
 
   Net cash provided by operating activities for the three months ended March
31, 1999 was $0.9 million. Net cash used by operating activities for the three
months ended March 31, 1998 and the years ended 1996, 1997 and 1998 was $2.1
million, $2.0 million, $2.5 million and $9.7 million, respectively. Cash used
in operating activities in each of these periods was primarily the result of
net losses, adjusted for non-cash items, including in 1997 and 1998
compensation expense; in 1998, acquired in-process research and development
expense; and in 1998 and the three months ending March 31, 1999, depreciation
and amortization expense primarily related to the goodwill recorded with the
acquisition of Viona, offset by increases in accounts receivable and increases
in inventory associated with the increase in hardware sales.
 
   Net cash provided by investing activities for the three months ended March
31, 1999 was $8,000. Net cash used by investing activities for the three months
ended March 31, 1998 and the years ended 1996, 1997 and 1998 was $0.06 million,
$0.1 million, $0.03 million and $4.0 million, respectively. Cash used in
investing activities in each period consisted primarily of net purchases of
furniture and equipment. In 1998, cash used in investing activities also
included the costs associated with the Viona acquisition.
 
   Net cash provided by financing activities for the three months ended March
31, 1998 and 1999 and the years ended 1996, 1997 and 1998 was $4.2 million,
$0.3 million, $2.1 million, $3.0 million and $14.2 million, respectively. Cash
provided by financing activities was primarily attributable to net proceeds
from the issuance of debt and equity securities to investors.
 
   As of March 31, 1999, the Company's principal commitments consisted of
obligations outstanding under equipment leases and notes payable to partially
fund its operations and capital purchases. The equipment leasing arrangements
consist primarily of Divicore paying rental fees to third party leasing
providers at interest rates between 15% to 18%, that maintain title to the
leased equipment. In most cases, there are no obligations for Divicore to
purchase the equipment at the end of the term. Although the Company has no
material commitments for capital expenditures, it anticipates a substantial
increase in its capital expenditures and lease commitments consistent with
anticipated growth in operations, infrastructure and personnel. In addition,
Divicore has approximately $2.5 million at March 31, 1999 of payments due over
the next two years to the former owners of Viona.
 
   As of March 31, 1999, Divicore had a $5 million line of credit with Silicon
Valley Bank. Under the terms of the line of credit, borrowings are subject to a
percentage of "eligible" accounts receivable and inventory, as defined in the
credit documentation, and bear interest at a rate of prime plus 1% per annum
(8.75% at December 31, 1998). In addition, Divicore must comply with certain
financial covenants. At March 31, 1999, approximately $1.3 million was
outstanding and $1.7 million was available under the line of credit. Divicore
was not in compliance with all material covenants under the agreement, but has
received a waiver from the
 
                                       39
<PAGE>
 
lender. This line of credit expires in July 2000. Silicon Valley Bank has
senior security interest in substantially all of the assets of Divicore.
 
   Divicore presently anticipates that the net proceeds from this offering,
together with existing sources of liquidity and cash anticipated to be provided
by operations, if any, together with borrowings available under its line of
credit, will be adequate to meet its cash needs for at least the next twelve
months.
 
Year 2000 Compliance
 
   Many currently installed computer systems and software products are coded to
accept or recognize only two digit entries in the date code field. These
systems and software products will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, computer
systems and/or software used by many companies and governmental agencies may
need to be upgraded to comply with such Year 2000 requirements or risk system
failure or miscalculations causing disruptions of normal business activities.
 
   Although Divicore's products, intellectual property and related designs have
no inherent time or date function, Divicore initiated a comprehensive
assessment of its Year 2000 readiness in March 1999. In parallel, Divicore has
recently started to implement programs to make both its information technology
and its non-information technology processes Year 2000 compliant. In addition,
Divicore has recently replaced its internal computer systems and operating and
applications software. Each of the suppliers of these systems and software has
indicated to Divicore that it believes its products are Year 2000 compliant.
Divicore expects to complete changes to critical systems by the third quarter
of calendar year 1999. Divicore believes that it has allocated sufficient
resources for its Year 2000 compliance efforts.
 
   To date, Divicore has not incurred any material expenditures in connection
with identifying, evaluating or addressing Year 2000 compliance issues. Most of
Divicore's expenses have related to, and are expected to continue to relate to,
the operating costs associated with time spent by employees in the evaluation
process and Year 2000 compliance matters generally. At this time, Divicore does
not possess the information necessary to estimate the potential costs of
revisions to its systems should such revisions be required or the replacement
of third-party software, hardware or services that are determined not to be
Year 2000 compliant. Although Divicore does not anticipate that such expenses
will be material, such expenses, if higher than anticipated, could harm its
business.
 
   Moreover, Divicore may discover Year 2000 compliance problems in its systems
that will require substantial revision. In addition, third-party software,
hardware or services incorporated into Divicore's information systems may need
to be revised or replaced, all of which could be time-consuming and expensive.
The failure of Divicore to fix or replace its third-party software, hardware or
services on a timely basis could result in lost revenues, increased operating
costs, the loss of customers and other business interruptions.
 
   As discussed above, Divicore is engaged in an ongoing Year 2000 assessment
and has not yet developed any contingency plans. The results of Divicore's Year
2000 assessment will be taken into account in determining the nature and extent
of any contingency plans.
 
Recent Accounting Pronouncements
 
   In March 1998, the American Institute of Certified Public Accountants, or
AICPA, issued Statement of Positions, or SOP, No. 98-1, Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use. SOP No. 98-1
requires entities to capitalize certain costs related to internal-use software
once certain criteria have been met. The adoption of SOP No. 98-1 did not have
a material effect on Divicore's capitalization policy.
 
   In April 1998, the AICPA issued SOP No. 98-5, Reporting on the Costs of
Start-Up Activities. SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, all
 
                                       40
<PAGE>
 
start-up costs that were capitalized in the past must be written off when SOP
No. 98-5 is adopted. Divicore has expensed these costs historically, therefore,
the adoption of SOP No. 98-5 did not have a material impact on Divicore's
financial position or results of operations.
 
   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard, or SFAS, No. 133, Accounting for Derivative
Instruments and Hedging Activities. SFAS No. 133 establishes methods for
derivative financial instruments and hedging activities related to those
instruments, as well as other hedging activities. Because Divicore does not
currently hold any derivative instruments and does not engage in hedging
activities, Divicore expects that the adoption of SFAS No. 133 will not have a
material impact on its financial position or results of operations. Divicore
will be required to implement SFAS No. 133 for the year ending December 31,
1999.
 
   In December 1998, the AICPA issued SOP 98-9, Modification of SOP 97-2,
Software Revenue Recognition, with respect to Certain Transactions. SOP 98-9
amends SOP 97-2 and SOP 98-4 extending the deferral of the application of
certain provisions of SOP 97-2 amended by SOP 98-4 through fiscal years
beginning on or before March 15, 1999. All other provisions of SOP 98-9 are
effective for transactions entered into in fiscal years beginning after March
15, 1999. Divicore does not expect the adoption of SOP 98-9 to have a material
effect on its results of operations or financial condition.
 
Qualitative and Quantitative Disclosures About Market Risk
 
   Divicore develops products in the United States and sells such products in
North America, Asia and Europe. As a result, Divicore's financial results could
be affected by factors such as changes in foreign currency exchange rates or
weak economic conditions in foreign markets. As all sales are currently made in
U.S. dollars, a strengthening of the dollar could make Divicore's products less
competitive in foreign markets. Divicore does not use derivative instruments to
hedge its foreign exchange risk. Divicore's interest income is sensitive to
changes in the general level of U.S. interest rates, particularly since the
majority of its investments are in short-term instruments. Due to the nature of
Divicore's short-term investments, Divicore has concluded that there is no
material market risk exposure. Therefore, no quantitative tabular disclosures
are required.

Industry Background
 
   Historically, the personal computer and consumer electronics industries
addressed video and audio content using different technologies. The personal
computer developed around digital technology using the central processing unit,
or CPU, which was initially expensive and unable to simultaneously run the
operating system and manipulate video and audio inputs at satisfactory
performance levels. As a result, digital video content was managed by a stand-
alone semiconductor device or module. In contrast, the consumer electronics
industry evolved using lower cost analog solutions that were able to provide
acceptable performance, but were typically passive and did not permit the users
to edit or enhance the content. Advances in semiconductor technology have
dramatically lowered the price of high performance microprocessors, allowing
personal computers and consumer electronics devices to employ software
solutions to manage video and audio streams in a digital format without
overburdening their CPUs. Moreover, today, when evaluating a digital personal
computer or consumer electronics device, consumers are increasingly demanding
digital video and audio capabilities such as
 
                                       42
<PAGE>
 
3-D graphics, editing and compression. Analog formatted devices cannot provide
these capabilities. Meanwhile, digital formats have emerged that provide higher
image resolution and quality, the opportunity to deliver a wide range of new
services and content, more efficient use of limited transmission spectrums and
the ability to deliver customized and interactive services. As a result, a
growing number of personal computer and consumer electronics manufacturers are
storing, accessing and playing video and audio streams in a digital format.
 
   A number of trends are accelerating the migration of manufacturers from
analog to digital technology, including advances in technology, the evolution
of standards, government and private initiatives and the increasing
availability of content.
 
    .  Advances in Technology. In the past, multiple silicon devices were
       needed to process digital video and audio streams. As silicon
       technology progressed, in many instances one such device was needed.
       Today, as microprocessor computing speeds continue to increase,
       software-only solutions are capable of providing video and audio
       stream management at a lower cost and at a performance level
       indistinguishable from dedicated silicon approaches.
 
    .  Evolution of Standards. Historically, a significant barrier to the
       growth of digital video and audio technology was the lack of widely
       accepted technological standards. Today, industry participants have
       adopted a video compression standard known as MPEG-2 that enables
       video and audio compression for digital transmission and storage.
       MPEG-2 is currently deployed as the DVD solution in personal
       computers and DVD players and has been adopted as the standard for
       digital television, or DTV, and HDTV. In addition, Dolby Digital,
       formerly known as AC-3, designed by Dolby Laboratories, has emerged
       as an industry standard for audio compression.
 
    .  Government and Private Initiatives. A number of government and
       private initiatives have also emerged to fuel the shift from analog
       to digital technology. For example, the cable television industry
       has adopted the "OpenCable" standard under which digital cable boxes
       will be manufactured and sold through retail channels similar to
       personal computers and television sets, thereby creating a new
       product market. Also, under the Telecommunications Act of 1996, all
       broadcasters are required to change their broadcasting formats to
       digital and to cease carrying analog broadcasts by 2006. This will
       require every owner of an analog television set to purchase either a
       new digital television set or a digital converter box in the next
       seven years.
 
    .  Increasing Availability of Content. The introduction of many forms
       of stand-alone content for digital media will lead consumers to shop
       for devices, such as DVD players and recorders, digital cable set-
       top devices and digital television sets, on which such content can
       be seen, heard, edited and stored. Already, there are over 2,300
       movie titles available in DVD format. The recording industry has
       adopted the DVD format to be used in next-generation audio devices.
       Cable television providers have adopted content strategies intended
       to capitalize on the trend toward digital technology through
       increased channel capacity and higher-resolution, interactive
       digital programming.
 
   Advances in microprocessor speed and capacity coupled with the shift to
digital technology are leading the personal computer and consumer electronics
markets to converge at an accelerating pace. As the personal computer and
consumer electronics industries converge, two major trends have emerged. First,
the integration of video and audio streams with digital technology is
increasing the complexity of product design. Second, products have shorter life
cycles as a result of rising digital processing capabilities, falling prices of
semiconductors and rapidly improving software. In the past, consumer
electronics products relied on multiple special-purpose silicon devices to
provide the necessary system performance, with each device performing a
particular function such as video or audio decoding. Similarly, the personal
computer industry has historically been driven by the latest in semiconductor
innovation and has timed product introductions around microprocessor advances,
which typically have occurred twice a year. These dedicated silicon strategies
carried two major risks: high product development cost and premature product
obsolescence. The risk of high product development cost came from the time and
effort required to adapt a silicon-based solution to address each new
 
                                       43
<PAGE>
 
feature or product platform. The risk of product obsolescence resulted from the
fixed-function nature of a dedicated silicon solution and the inability of
manufacturers to rapidly change product offerings in light of changes in
consumer preferences for applications or functionality. As the speed of
microprocessors increased, the ability to shift more and more complex tasks
from dedicated silicon devices to software increased. As a result, personal
computer and consumer electronics manufacturers are now able to use digital
solutions with a more-adaptable and inexpensive software-only format, giving
them the flexibility to innovate without the risk of quick obsolescence.
 
   Divicore believes that personal computer and consumer electronics
manufacturers are seeking to leverage their expertise and brand recognition in
order to deliver digital products that provide a new set of choices for
consumers in new markets. For example, all existing television sets, video
cassette recorders, stereos, set-top boxes and personal computers are
candidates for upgrade to digital technologies. In order to enter into these
new markets and capitalize on upgrade cycles for these products, personal
computer and consumer electronics manufacturers are seeking new digital product
solutions that permit rapid time-to-market with the latest features and
functionality. Divicore believes that these product solutions must be
extensible and have a customizable architecture that allows product
differentiation and facilitates migration across product lines and markets. In
particular, in order to keep pace with the rapidly-changing product cycles of
personal computer and consumer electronics manufacturers and be cost effective,
these product solutions must rely on platform-independent software and not on
dedicated silicon device designs and their associated operating systems.
 
The Divicore Solution
 
   Divicore designs, develops, licenses and markets innovative core-based
modular software solutions and supporting hardware designs that enable digital
video and audio stream management in personal computer systems and consumer
electronics devices. Divicore's solution contains high-performance digital
video and audio decoding and encoding engines that implement complex
synchronization and optimization algorithms, which, in turn, enable decoding
and encoding of media formats such as DVD, DBS/DVB and HDTV on existing
personal computer and consumer electronics platforms. Divicore's digital
solutions incorporate industry standards for video and audio compression and
are independent of operating systems and silicon components. By using
Divicore's solution, its customers can provide various video and audio
processes normally completed by dedicated silicon devices with software modules
at a fraction of the cost.
 
   Divicore believes that its digital solutions provide a number of significant
advantages for personal computer and consumer electronics manufacturers.
Divicore's personal computer and consumer electronics products are built using
the same powerful, easily customizable and modular software architecture. This
modular approach provides Divicore's customers with enhanced flexibility,
enabling them to rapidly introduce products to market. In addition, using
Divicore's software solutions frees these customers from semiconductor design
cycles. As digital technology evolves and standards change, Divicore can add
new modules to its software to address the changes without needing to alter
existing components of its digital solution.
 
   Examples of how Divicore's digital solutions are being implemented include:
 
    .  In the personal computer market, Dell Computer uses Divicore's DVD
       decoding solutions in all of its DVD-enabled desktop personal
       computers. Dell Computer has migrated Divicore's solution across
       multiple product cycles through Divicore's customization and
       optimization services, even when the different cycles involve
       changing graphics requirements and different microprocessors. The
       Divicore digital solution allows Dell Computer to use the same user
       interface in each of these DVD-enabled product lines while
       maintaining high quality video and audio performance and rapid time-
       to-market delivery.
 
    .  In the consumer electronics market, Sanyo Electronics, by using
       Divicore's software solution and supporting hardware platform
       design, can now offer high quality video and audio performance
       together with significant cost savings in its DVD players.
       Divicore's technology is designed to enable Sanyo Electronics to
       migrate this platform to accommodate additional technologies such as
       DBS/DVB, DTV and HDTV.

Strategy
 
   Divicore's strategy is to be the leading global provider of digital video
and audio solutions to personal computer and consumer electronics
manufacturers. Divicore believes that the most effective way to achieve its
strategy is to become an intellectual property company that licenses its
technology to manufacturers that will, in turn, use Divicore's solutions to
penetrate very large personal computer and consumer electronics markets. Key
elements of Divicore's strategy include:
 
   Grow License Business Model Among Top Tier Personal Computer and Consumer
Electronics Manufacturers. Divicore's strategy is to license its software
solutions and supporting hardware designs to leading personal computer and
consumer electronics manufacturers. Divicore believes that the success of its
manufacturing customers in the digital video and audio markets will continue to
validate its technology. Divicore intends to leverage its existing customer
relationships into additional product lines and to seek out additional personal
computer and consumer electronics manufacturers as customers. Divicore believes
that its license model avoids the pitfalls of manufacturing, storing and
distributing hardware-based digital solutions while simultaneously increases
profitability. Divicore also believes that by developing customized solutions
in partnership with its customers, it will avoid commoditization of its
products.
 
   Extend Technological Leadership. Divicore has established its line of
CineMaster products as a leading DVD solution for the personal computer market.
Divicore's experience in providing digital video and audio technologies has
enabled it to stay at the forefront of the transition to digital technologies.
For example, Divicore believes it was the first company to display a working
DVD decode solution on a personal computer, the first company to demonstrate an
HDTV decode solution on a personal computer and the first company to display an
all-software HDTV decode solution. Divicore intends to continue to invest in
research and development both internally and in conjunction with its customers
and strategic partners in order to maintain its technological leadership,
improve its current product offerings and leverage its proprietary
technologies.
 
   Leverage Technology and Expertise into New Markets. Divicore intends to
leverage its modular software solutions and DVD expertise into multiple
consumer electronics markets, such as the emerging DTV, HDTV, DBS/DVB and
digital cable markets. Divicore believes that these markets will undergo
dramatic growth in the next few years and that the extensibility of its
products across multiple digital markets will provide it with an advantage over
competitors focused on a single product, technology or market. In the future,
Divicore plans to supplement its distribution channel by establishing an
Internet presence to maximize direct contact with its customers, facilitate
electronic sales of its products and sell associated products directly to end
users.
 
   Focus on Strategic Relationships. Divicore's solutions are incorporated into
the products of seven of the top ten personal computer manufacturers and two
leading consumer electronics manufacturers. In addition, Divicore has
established strategic relationships with leading technology companies, such as
ATI Technologies, Dolby Laboratories, Intel and STMicroelectronics. Divicore
believes these industry relationships better position it to stay abreast of
industry trends, respond to the needs of its customers, provide input into
industry standards and improve its product planning process. Divicore intends
to continue to develop its existing strategic relationships and develop new
strategic relationships in targeted areas.
 
Technology
 
   Divicore has designed its digital video and audio stream management
solutions to be independent of the hardware platform on which they run.
Divicore's designs are based on an object-oriented modular architecture,
whereby each of the technical standards that are used for various digital media
is addressed through a separate module of Divicore's software. For example,
compliance with MPEG-2 and Dolby Digital has been achieved through completely
discrete components of Divicore's software that can be "plugged in" to each
other or to other modules addressing other standards or features of Divicore's
products. Furthermore, each of these modules can address particular
semiconductors or central processing units (CPUs) as needed. As a result,
Divicore's architecture allows personal computer and consumer electronics
manufacturers to choose different
 
                                       45
<PAGE>
 
combinations of software and hardware configurations for their products while
maintaining a consistent look and feel.
 
   Divicore's module-based approach to its digital solutions is designed to
provide flexibility and adaptability as relevant technologies evolve and
standards change. For example, as new digital technology develops, whether
hardware or software-based, Divicore can add new modules to address the new
technology without altering other components of its digital solution. In
addition, as the processing speeds and capabilities of personal computers and
graphics cards improve, hardware-based modules can be replaced with software
modules, again without requiring the alteration of other components of
Divicore's overall architecture. The same flexibility also applies to the user
interface and storage modules. For example, as new platforms and operating
environments arrive, only the interface modules will need to be altered to
adapt.
 
   Divicore identifies emerging technologies necessary for future platforms
which address various media sources such as those shown below. Divicore then
applies its high-performance modular software solution to manage these sources
in a digital format, enabling manufacturers to support these technologies in
various devices:

    .  Source Management
 
      Divicore's digital video and audio source management solution starts
      by controlling and decoding multiple video and audio streams from
      either digital or digitally converted analog sources.
 
    .  Media Router/Media Caching
 
      After the streams are received and converted, they are directed via
      the "Media Router" module to either store the streams for future
      playback using the "Media Caching" module, or deliver them to the
      media decoder for immediate presentation.

<PAGE>
 
    .  Media Decode/Convergence User Interface/Intelligent Agent
 
      Upon delivery, the "Media Decode" module translates the compressed
      data into video and audio streams. At this point, Divicore's
      "Convergence User Interface" module allows users to control the
      final presentation of the stream as well as to provide a customized
      look and feel. Divicore plans to add intelligent agents that would
      enable user habit-based automatic programming and simultaneous
      playback and recording capabilities.
 
    .  User Presentation
 
      As a final step, Divicore's "User Presentation" module converts the
      audio and video streams to the proper output format for presentation
      on multiple devices including computer monitors, television sets and
      speakers.
 
Products and Services
 
 Products
 
   Divicore's products incorporate its core-based, high-performance,
customizable, modular software solutions and supporting hardware designs to
enable digital video and audio playback and recording within the personal
computer and consumer electronics industries. Divicore currently offers two
complete DVD solutions for personal computers, a DVD player solution for
consumer electronics products and has several products under development for
other digital video and audio applications. Divicore's current products
include:
 
    .  Hardware CineMaster 98, a software DVD solution with a supporting
       hardware platform design that is incorporated into the systems of
       three major personal computer manufacturers to enable DVD playback
       in their products. A Dell Computer system incorporating Hardware
       CineMaster 98 won the Editors' Choice Award for high-end personal
       computers in December 1998 in both PC World and PC Magazine. Both
       awards cited the quality of the DVD playback in general and
       Divicore's solution in particular. Historically, Divicore derived
       hardware revenue from, and was responsible for, the manufacture and
       delivery of this product. In early 1999, Divicore began to contract
       with third party manufacturers to manufacture and deliver this
       product directly to Divicore's customers. Divicore will receive a
       license fee for each unit sold.
 
    .  Software CineMaster 98, a software-only DVD solution that has been
       licensed to seven of the top ten personal computer manufacturers to
       enable DVD playback in their products. Software CineMaster 98 is
       incorporated into the operating system of personal computers or sold
       separately as part of an after-market solution bundled with a
       graphics card. Compaq Computer and Gateway systems incorporating
       Software CineMaster 98 won the PC Magazine Editors' Choice Award in
       March 1999 and December 1998, respectively. These awards cited both
       the quality of the DVD playback in these systems and Divicore's
       Software CineMaster 98 product as responsible for DVD decoding in
       these systems. Divicore receives a per unit license fee from
       manufacturers for each system or device sold by them which
       incorporates this product.
 
    .  CineMaster CE, a software solution with multiple supporting hardware
       platform designs that enables DVD playback across a variety of
       consumer electronic products. CineMaster CE was developed through
       Divicore's strategic relationship with a top tier semiconductor
       manufacturer to whom Divicore has licensed the product on a
       nonexclusive basis. CineMaster CE includes a complete DVD set-top
       reference design, including lower level software, a complete
       hardware design and a front-end graphical user interface. CineMaster
       CE was introduced in late 1998 and has already achieved design wins
       from Sanyo Electronics and Yamaha. Divicore receives a per unit
       license fee for each microprocessor that incorporates its technology
       in addition to the license fee it receives on a per unit basis from
       the consumer electronics device manufacturer.

 Services
 
   Divicore's engineers offer customization of key components and functionality
of Divicore's products. These customization services consist primarily of
services that embed Divicore's core technology into components of other
vendors' solutions and modify existing user interface designs. Divicore also
provides broad customer service capabilities, which are necessary to support
the documentation and help file requirements of rapidly changing software.
Divicore's extensive customer service, customization and support capabilities
have differentiated Divicore from its competition and allowed for its success
with top tier personal computer and consumer electronics manufacturers.
 
Markets and Applications
 
   Over the next ten years, Divicore expects the consumer electronics market to
experience a significant upgrade cycle as analog devices such as VCRs, set-top
cable boxes, audio players and televisions are replaced with digital devices.
Divicore believes its digital video and audio solutions will enable personal
computer and consumer electronics manufacturers to provide the next generation
of digital devices required in this upgrade cycle. A few of the current and
future applications for these devices are the following:
 
   Digital Versatile Disc. DVD is the next generation of five-inch optical disc
technology. A DVD is the same size as a compact disc but holds up to twenty-
five times more data and is up to nine times faster. DVD drives are also
"backward-compatible" with compact disc drives. This increased capacity allows
a DVD to store both high-quality digital video and audio and positions DVD as
the natural successor to compact discs, especially in home application segments
such as personal computers, video entertainment and video game consoles. As
this transition occurs and rental markets, software developers and hardware
vendors embrace the new technology, the DVD market is expected to experience
rapid growth. International Data Corporation predicts that the number of DVD
ROM units sold worldwide will grow from 6.1 million units in 1998 to
19.2 million units in 1999 and 97.4 million units in 2002, representing a
compound annual growth rate of 100%. Divicore is currently shipping various
products for the decoding and playback of DVD titles on a personal computer,
including a software-only solution and a software solution with a supporting
hardware platform design. Divicore also offers a software solution with
multiple supporting hardware designs for DVD playback on consumer electronics
platforms and is developing a software-only DVD encoding solution that enables
the recording of video and audio streams in the DVD format.
 
   Digital Television. A key strategy of Divicore is to pursue the DTV market,
which Divicore expects to be the next major technological advancement in home
electronics. According to The Yankee Group, there is an installed base of 250
million analog television sets in the United States alone that will ultimately
require a separate set-top box or upgrade to accommodate digital technologies.
Digital broadcast television was first successfully launched in the United
States in 1996 via DBS, with DBS now delivering direct broadcast television to
over five million households today. DTV has also begun to move into the large
over-the-air market and by the end of 1999, there is expected to be one digital
broadcast station in each of the top ten U.S. markets. Under the
Telecommunications Act of 1996, all broadcasts must be in a digital format by
2006. Divicore is currently developing a software-only solution and a software
solution with a supporting hardware platform design that enable the viewing of
DTV streams on a personal computer. Divicore is also developing a software
solution with multiple supporting hardware designs for DTV viewing on consumer
electronics platforms.
 
   Digital Cable. In an effort to deliver more channels and services, including
online and interactive services, cable providers are beginning to upgrade
analog cable boxes with digital boxes. For example, Tele-Communications, Inc.
and eight other multiple cable system operators announced in January 1999 the
purchase of 15 million digital cable set-tops from General Instrument
Corporation. Divicore has not shipped any digital cable products to date, but
is developing a software-only solution and a software solution with a
supporting hardware platform design that will enable the viewing of digital
cable television streams using a personal computer or digital cable set-top
device.

Sales and Marketing
 
   Divicore's sales and marketing activities are focused on establishing and
maintaining license arrangements with personal computer, peripherals, consumer
electronics and semiconductor manufacturers. Divicore licenses its digital
solutions on a non-exclusive worldwide basis to personal computer, peripherals
and consumer electronics manufacturers which sell products incorporating these
technologies to end users. Divicore also licenses its digital solutions on a
non-exclusive worldwide basis to semiconductor manufacturers which incorporate
Divicore's technology in products for personal computers and consumer
electronics devices.
 
   Divicore sells its digital solutions to personal computer manufacturers in
the United States and Europe through its direct sales force, and to personal
computer manufacturers in Japan through an independent sales representative.
Divicore is beginning to market its digital solutions to consumer electronics
manufacturers. Sales to these manufacturers will be managed domestically and in
Europe through its direct sales force and in Japan through a strategic sales
partner.
 
   Divicore establishes strategic relationships with peripherals and
semiconductor manufacturers in order to establish Divicore's core-based modular
software solution as the standard of the digital video and audio stream
management industry. In addition to its strategic relationships with
semiconductor manufacturers such as STMicroelectronics, Divicore works closely
with major software and hardware providers such as Advanced Micro Devices,
Inc., ATI Technologies and Intel in designing its digital solutions so that its
final product will interact smoothly with their software and hardware
platforms. Divicore also maintains close relationships with a wide variety of
graphics card vendors to maximize its product flexibility and support. Divicore
works closely with its customers to anticipate market demand and user
requirements and to maximize consumer acceptance and long-term viability of its
solutions. Divicore intends to supplement its distribution channel in the
future by establishing an Internet presence to maximize direct contact with its
customers, facilitate electronic sales of its products and sell associated
products directly to end users.
 
   Divicore participates in industry conferences to market and demonstrate its
technology and distributes quarterly press kits to disseminate information
regarding its latest advances. Divicore also participates in consortia which
meet to establish standards for digital media.
 
Customers
 
   Divicore's typical customers are personal computer, consumer electronics,
peripherals and semiconductor manufacturers that benefit from a software-only
or combination software and hardware solution. As of March 31, 1999, computer
and peripherals manufacturers shipping products that incorporate Divicore
technology included: ATI Technologies, Compaq Computer, Dell Computer, ELSA,
Fountain Technologies, Fujitsu Microelectronics, Gateway, Hewlett-Packard,
Micron Electronics, Packard-Bell NEC Europe and Sony Electronics, Inc. In
addition, consumer electronics manufacturers who have incorporated Divicore's
technology include Sanyo Electronics, STMicroelectronics and Yamaha. In 1998,
one customer, Dell Computer, accounted for in excess of 10% of Divicore's
revenues; in 1997, two customers, Hi-Val, Inc. and Pacific Digital Products,
Inc., accounted for in excess of 10% of Divicore's revenues; and in 1996, one
customer, UEP Systems, Inc. accounted for in excess of 10% of Divicore's
revenues.
 
Research and Development
 
   Divicore believes that its future competitive position will depend in large
part on its ability to develop new and enhanced digital video and audio
solutions and its ability to meet the evolving and rapidly changing needs of
personal computer, consumer electronics, peripherals and semiconductor
manufacturers. Divicore has invested significant time and resources in creating
a structured process for undertaking all product development. This process
involves several functional groups within Divicore and is designed to provide a
framework for defining and addressing the activities required to bring product
concepts and development projects to market. Divicore has assembled a core team
of experienced software architects, software engineers and system hardware
engineers.
 
                                       50
<PAGE>
 
   As of March 31, 1999, Divicore employed a total of 63 research and
development personnel in three offices. In the years ending December 31, 1998,
1997 and 1996, Divicore's research and development expenditures totaled $3.1
million, $1.8 million and $1.0 million, respectively. To date, Divicore has not
capitalized any research and development expenses.
 
Intellectual Property and Proprietary Rights
 
   Divicore relies upon a combination of patent, copyright, trade secret and
trademark laws to protect its intellectual property. Divicore currently has
three pending U.S. patent applications related to its digital video and audio
stream management technology. In addition, Divicore has a pending trademark
application for the mark "Divicore" and a second pending trademark application
for the mark "CineMaster" which has been approved for publication by the United
States Patent and Trademark Office. Although Divicore relies on patent,
copyright, trade secret and trademark laws to protect its technology, Divicore
believes that factors such as the technological and creative skill of its
personnel, new product developments, frequent product enhancements and reliable
product maintenance are more essential to establishing and maintaining
technology leadership position. Others may develop technologies that are
similar or superior to Divicore's technology.
 
   Divicore generally enters into confidentiality or license agreements with
its employees and consultants and corporations with whom it has strategic
relationships, and generally controls access to and distribution of its
software, documentation and other proprietary information. In addition,
Divicore often incorporates the intellectual property of its strategic
customers into its designs and has obligations with respect to the use and
disclosure of such intellectual property. Despite Divicore's efforts to protect
its proprietary rights, unauthorized parties may attempt to copy or otherwise
obtain and use its products or technology or to develop products with the same
functionality as Divicore's products. Policing unauthorized use of its products
is difficult, and Divicore cannot be certain that the steps it has taken will
prevent misappropriation of its technology, particularly in foreign countries
where the laws may not protect proprietary rights as fully as do the laws of
the United States.
 
   The market for digital video and audio software and hardware solutions is
characterized by vigorous protection and pursuit of intellectual property
rights. From time to time, Divicore has received, and it expects to continue to
receive, notice of claims of infringement of other parties' proprietary rights.
For example, Divicore has recently received notice from two of its customers
who are personal computer manufacturers that a third party with substantial
financial resources has alleged that aspects of MPEG-2 technology infringe upon
patents held by the third party. The third party has invited these customers to
license the technology covered by the patents. These customers have contacted
Divicore for assistance in determining whether its technology falls within the
scope of the asserted patent claims and may in the future seek compensation or
indemnification from us arising out of the third-party claims. In addition, a
consortium of companies known as MPEG-LA has notified a number of personal
computer manufacturers, including our customers, that patents owned by members
of the consortium are infringed by the personal computer manufacturers in their
distribution of MPEG-2 technology. MPEG-LA has requested that these personal
computer manufacturers pay license royalties for use of the technology covered
by MPEG-LA patents. These personal computer manufacturers may in the future
seek compensation or indemnification from Divicore arising out of the MPEG-LA
claims. Also, a third party has asserted that the parental control features of
Divicore's CineMaster products infringe certain patents held by the third
party. Divicore believes these claims to be without merit. These and any other
claims of infringement against Divicore, whether or not such claims have merit,
could result in litigation. Any litigation related to intellectual property,
brought by us or others, could result in the expenditure of significant
financial and managerial resources. In addition, litigation in which Divicore
is accused of infringement may cause product shipment delays, require Divicore
to develop non-infringing technology, or require Divicore to enter into royalty
or license agreements even before the issue of infringement has been decided on
the merits. If any such litigation is not resolved in Divicore's favor, it
could become subject to substantial damage claims and also be enjoined from the
continued use of the technology at issue unless it enters into a royalty or
license agreement. Such royalty or license agreements, if required, might not
be available on acceptable terms, or at all, and could harm Divicore's
business. If a successful claim of patent infringement were made against
 
                                       51
<PAGE>
 
Divicore and Divicore could not develop non-infringing technology or license
the infringed or similar technology on a timely and cost-effective basis, its
business could be significantly harmed.
 
Competition
 
   Divicore competes in markets that are new, intensely competitive, highly
fragmented and rapidly changing. Divicore competes on the basis of performance,
functionality, feature sets and price in both the software-based and hardware-
based video and audio stream management markets. Divicore's competitors in the
software-based digital solution market include Mediamatics, Inc. (a division of
National Semiconductor), Zoran Corporation and Xing Technology Corporation
(which has agreed to be acquired by RealNetworks, Inc.). Divicore's competitors
in the hardware-based digital solution market include Sigma Designs, Inc. and
several smaller competitors. Divicore also competes with the research and
development departments of other software companies, as well as those of
personal computer, consumer electronics, peripherals and semiconductor
manufacturers who are in the market for specific digital video or audio
software applications. Divicore is aware of numerous other major personal
computer manufacturers, software developers and other companies that are
focusing significant resources on developing and marketing products and
services that will compete with Divicore's CineMaster products. Semiconductor
manufacturers are positioning their products as offering hardware-based digital
video and audio management capabilities and marketing such products as equal or
superior to Divicore's CineMaster products. In the future, operating system
providers with a larger established customer base, such as Microsoft, may enter
the digital video or audio stream management markets by building video or audio
stream management applications into their operating systems. Personal computer
and consumer electronics manufacturers may use such products as their digital
solutions.
 
   Divicore anticipates continued growth and competition in the digital video
industry, the entrance of new competitors into the market, and that the market
for its products will remain intensely competitive. Many of Divicore's current
and potential competitors have significantly more personnel and greater
financial, technical, marketing and other resources than Divicore.
 
Employees
 
   As of March 31, 1999, Divicore had a total of 106 full-time employees, 63 of
whom were engaged in research and development, 11 in operations, 14 in sales
and marketing, 10 in program management and 8 in administration. Divicore's
future performance depends in significant part upon the continued services of
its key technical, sales and senior management personnel. The loss of the
services of one or more of Divicore's key employees could harm its business.
Divicore's future success also depends on its continuing ability to attract,
train and retain highly qualified technical, sales and managerial personnel.
Competition for such personnel is intense, particularly in the Philadelphia
area, where Divicore is headquartered. Divicore may not be able to retain or
attract key personnel in the future. None of Divicore's employees are
represented by a labor union. Divicore has not experienced any work stoppages
and considers its relations with employees to be good.
 
Facilities
 
   Divicore leases an aggregate of approximately 12,000 square feet in an
office complex located in Malvern, Pennsylvania. Divicore occupies this space
under a lease expiring in September 2003. In addition to its principal office
space in Malvern, Divicore also leases office space in Lancaster, Pennsylvania,
San Jose, California and Karlsruhe, Germany. These leases are for facilities
ranging from 1,200 square feet to 8,600 square feet and have terms ranging from
month-to-month to 10 years. As of March 31, 1999, 65 of Divicore's employees
worked in its Malvern facility, 10 in its Lancaster facility, 14 in its San
Jose facility and 17 in its Karlsruhe facility. Divicore expects that it will
need to obtain additional office space in the next twelve months.
 
Legal Proceedings
 
   Divicore is not currently party to any legal proceedings.

(1) The option was originally granted with an exercise price in excess of $2.52
    per share and was cancelled on September 23, 1998 in exchange for a new
    option for the number of shares subject to the option at the time of the
    regrant with an exercise price of $2.52 per share, the fair market value
    per share of Common Stock on the date of regrant.
 
   In 1998, Divicore granted options to purchase up to an aggregate of
1,792,897 shares to employees, directors and consultants, of which 572,170
grants were attributable to deemed regrants of options granted prior to
September 23, 1998 as the result of their repricing on such date to an exercise
price of $2.52 per share. Options to purchase 783,333 shares were granted
outside of Divicore's 1995 Stock Option Plan and options to purchase 1,009,563
shares were granted under Divicore's 1995 Stock Option Plan at exercise prices
at the fair market value of Divicore's common stock on the date of grant, as
determined in good faith by the Board of Directors. The exercise price may be
paid in cash, with shares of common stock or through a cashless exercise price.
All options became exercisable over a four-year period, with 25% of the shares
vesting on the one year anniversary of the grant date and the remainder vesting
in 36 equal monthly installments. To the extent not already exercisable, all of
these options will become exercisable in the event of an acquisition of
Divicore. All options have a term of five years, subject to earlier termination
in certain situations related to termination of employment. Notwithstanding the
foregoing, Mr. Wilde was granted options to purchase 166,667 shares in 1998
which vested upon the achievement of specific performance milestones at the
time of grant. In addition, options granted to Mr. Sharp to purchase 5,833
shares were subject to certain performance goals for vesting purposes, which
were met and these options have fully vested.

                                 Benefit Plans
 
1999 Stock Incentive Plan
 
   Introduction. The 1999 Stock Incentive Plan is intended to serve as the
successor program to Divicore's 1995 Stock Option Plan. Divicore's 1999 Stock
Incentive Plan was adopted by the board in April 1999 and is expected to be
approved by the stockholders in May 1999. The 1999 Stock Incentive Plan became
effective upon its adoption by the board. All outstanding options under
Divicore's existing 1995 Stock Option Plan will be transferred to the 1999
Stock Incentive Plan on the date of this offering, and no further option grants
will be made under the 1995 Stock Option Plan. The transferred options will
continue to be governed by their existing terms, unless Divicore's compensation
committee decides to extend one or more features of the 1999 Stock Incentive
Plan to those options. Except as otherwise noted below, the transferred options
have substantially the same term as will be in effect for grants made under the
discretionary option grant program of Divicore's 1999 Stock Incentive Plan.
 
   Share Reserve.           shares of Divicore's common stock have been
authorized for issuance under the 1999 Stock Incentive Plan. This share reserve
consists of the number of shares Divicore estimates will be carried over from
the 1995 Stock Option Plan plus an additional increase of
shares. The share reserve under Divicore's 1999 Stock Incentive Plan will
automatically increase on the first trading day in January each year, beginning
January 1, 2000, by an amount equal to one percent of the total number of
shares of common stock outstanding on the last trading day of the prior month,
but in no event will this annual increase exceed         shares. In addition,
no participant in Divicore's 1999 Stock Incentive Plan may be granted stock
options or direct stock issuances for more than             shares of common
stock in total in any calendar year.
 
   Programs. Divicore's 1999 Stock Incentive Plan has three separate programs:
 
  .  the discretionary option grant program, under which eligible individuals
     in Divicore's employ may be granted options to purchase shares of
     Divicore's common stock at an exercise price determined by the plan
     administrator;
 
  .  the stock issuance program, under which eligible individuals may be
     issued shares of common stock directly, upon the attainment of
     performance milestones or upon the completion of a period of service or
     as a bonus for past services; and
 
                                       59
<PAGE>
 
  .  the automatic option grant program, under which option grants will be
     made at periodic intervals to eligible non-employee board members to
     purchase shares of common stock at an exercise price equal to the fair
     market value of those shares on the grant date.
 
   The individuals eligible to participate in Divicore's plan include its
officers and other employees, its board members and any consultants it hires.
 
   Administration. The discretionary option grant and stock issuance programs
will be administered by Divicore's compensation committee. This committee will
determine which eligible individuals are to receive option grants or stock
issuances under those programs, the time or times when the grants or issuances
are to be made, the number of shares subject to each grant or issuance, the
status of any granted option as either an incentive stock option or a
nonstatutory stock option under the federal tax laws, the vesting schedule to
be in effect for the option grant or stock issuance and the maximum term for
which any granted option is to remain outstanding.
 
   Plan Features. Divicore's 1999 Stock Incentive Plan will include the
following features:
 
  .  The exercise price for any options granted under the plan may be paid in
     cash or in shares of Divicore's common stock valued at fair market value
     on the exercise date. The option may also be exercised through a same-
     day sale program without any cash outlay by the optionee.
 
  .  The compensation committee will have the authority to cancel outstanding
     options under the discretionary option grant program, including any
     transferred options from Divicore's 1995 Stock Option Plan, in return
     for the grant of new options for the same or different number of option
     shares with an exercise price per share based upon the fair market value
     of Divicore's common stock on the new grant date.
 
  .  Stock appreciation rights may be issued under the discretionary option
     grant program. These rights will provide the holders with the election
     to surrender their outstanding options for a payment from Divicore equal
     to the fair market value of the shares subject to the surrendered
     options less the exercise price payable for those shares. We may make
     the payment in cash or in shares of Divicore's common stock. None of the
     options under Divicore's 1995 Stock Option Plan have any stock
     appreciation rights.
 
  .  Limited stock appreciation rights will automatically be included as part
     of each grant made under the automatic option grant program, and these
     rights may also be granted to one or more officers as part of their
     option grants under the discretionary option grant program. Options with
     this feature may be surrendered to Divicore upon the successful
     completion of a hostile tender offer for more than 50% of Divicore's
     outstanding voting stock. In return for the surrendered option, the
     optionee will be entitled to a cash distribution from us in an amount
     per surrendered option share based upon the highest price per share of
     Divicore's common stock paid in that tender offer.
 
   Change in Control. The 1999 Stock Incentive Plan will include the following
change in control provisions which may result in the accelerated vesting of
outstanding option grants and stock issuances:
 
  .  In the event that Divicore is acquired by merger or asset sale or a
     board-approved sale of more than fifty percent of Divicore's stock by
     its stockholders, each outstanding option under the discretionary option
     grant program which is not to be assumed or continued by the successor
     corporation will immediately become exercisable for all the option
     shares, and all outstanding unvested shares will immediately vest,
     except to the extent Divicore's repurchase rights with respect to those
     shares are to be assigned to the successor corporation.
 
  .  The compensation committee will have complete discretion to grant one or
     more options which will become exercisable for all the option shares in
     the event those options are assumed in the acquisition but the
     optionee's service with Divicore or the acquiring entity is subsequently
     terminated. The
 
                                       60
<PAGE>
 
     vesting of any outstanding shares under Divicore's 1999 Stock Incentive
     Plan may be accelerated upon similar terms and conditions.
 
  .  The compensation committee may grant options and structure repurchase
     rights so that the shares subject to those options or repurchase rights
     will immediately vest in connection with a successful tender offer for
     more than fifty percent of Divicore's outstanding voting stock or a
     change in the majority of Divicore's board through one or more contested
     elections. Such accelerated vesting may occur either at the time of such
     transaction or upon the subsequent termination of the individual's
     service.
 
  .  The options currently outstanding under Divicore's 1995 Stock Option
     Plan will immediately vest upon an acquisition of Divicore by merger or
     asset sale or sale of more than fifty percent of Divicore's outstanding
     stock by its stockholders. There are no other change in control
     provisions currently in effect for those options. However, the
     compensation committee may extend the acceleration provisions of
     Divicore's 1999 Stock Incentive Plan to any or all of those options.
 
   Automatic Option Grant Program. Each individual who is serving as a non-
employee board member on the date the underwriting agreement for this offering
is executed will automatically receive on such date an option to purchase
20,000 shares of Divicore's common stock, provided he has not been in the prior
employ of Divicore. Each individual who first becomes a non-employee board
member at any time after this offering will automatically receive on the date
of his or her appointment, an option to purchase 20,000 shares of Divicore's
common stock. On the date of each annual stockholders meeting following this
offering, each individual who is to continue to serve as a non-employee board
member will automatically be granted an option to purchase 5,000 shares of
Divicore's common stock, provided he or she has served on the board for at
least six months.
 
   Each automatic grant will have a term of ten years, subject to earlier
termination following the optionee's cessation of board service. The option
will be immediately exercisable for all of the option shares; however, any
unvested shares purchased under the option will be subject to repurchase by
Divicore, at the exercise price paid per share, should the optionee cease board
service prior to vesting in those shares. The shares subject to each 20,000
share initial automatic option grant will vest over a four year period in
successive equal annual installments upon the individual's completion of each
year of board service over the four year period measured from the option grant
date. Each 5,000 share subsequent automatic option grant will vest upon the
individual's completion of one year of board service measured from the option
grant date. However, the shares subject to each automatic grant will
immediately vest in full upon certain changes in control or ownership of
Divicore or upon the optionee's death or disability while a board member.
 
   The board may amend or modify the 1999 Stock Incentive Plan at any time,
subject to any required stockholder approval. The 1999 Stock Incentive Plan
will terminate no later than April 29, 2009.
 
1999 Employee Stock Purchase Plan
 
   Introduction. Divicore's 1999 Employee Stock Purchase Plan was adopted by
the board in April 1999 and is expected to be approved by the stockholders in
May 1999. The plan will become effective immediately upon the execution of the
underwriting agreement for this offering. The plan is designed to allow
eligible employees of Divicore and its participating subsidiaries to purchase
shares of common stock, at semi-annual intervals, with their accumulated
payroll deductions.
 
   Share Reserve. 500,000 shares of common stock will initially be reserved for
issuance.
 
   Offering Periods. The plan will have a series of successive offering
periods, each with a maximum duration of 24 months. The initial offering period
will start on the date the underwriting agreement for the offering covered by
this prospectus is signed and will end on the last business day in July 2001.
The next offering period will start on the first business day in August 2001,
and subsequent offering periods will be set by Divicore's compensation
committee. Shares will generally be purchased on the last business day of
January and July during each offering period.
 
                                       61
<PAGE>
 
   Reset Feature. If the fair market value per share of Divicore's common stock
on any purchase date is less than the fair market value per share on the start
date of the two-year offering period, then that offering period will
automatically terminate, and a new two-year offering period will begin on the
next business day. All participants in the terminated offering will be
transferred to the new offering period.
 
   Eligible Employees. Individuals scheduled to work more than 20 hours per
week for more than 5 calendar months per year may join an offering period on
the start date or any semi-annual entry date within that period. Semi-annual
entry dates will occur on the first business day of February and August each
year. Individuals who become eligible employees after the start date of an
offering period may join the plan on any subsequent semi-annual entry date
within that offering period.
 
   Payroll Deductions. A participant may contribute up to 15% of his or her
cash earnings through payroll deductions, and the accumulated deductions will
be applied to the purchase of shares on each semi-annual purchase date. The
purchase price per share will be equal to 85% of the fair market value per
share on the participant's entry date into the offering period or, if lower,
85% of the fair market value per share on the semi-annual purchase date. Semi-
annual purchase dates will occur on the last business day of January and July
each year. In no event, however, may any participant purchase more than 1,300
shares on any purchase date, and not more than 125,000 shares may be purchased
in total by all participants on any purchase date.
 
   Change in Control. Should Divicore be acquired by merger or sale of
substantially all of Divicore's assets or more than fifty percent of its voting
securities, then all outstanding purchase rights will automatically be
exercised immediately prior to the effective date of the acquisition. The
purchase price will be equal to 85% of the market value per share on the
participant's entry date into the offering period in which an acquisition
occurs or, if lower, 85% of the fair market value per share immediately prior
to the acquisition.
 
   The plan will terminate no later than the last business day of July 2009.
The board may at any time amend, suspend or discontinue the plan. However,
certain amendments may require stockholder approval.
 
Employment Contracts, Termination of Employment Agreements and Change in
Control Arrangements
 
   In August 1997, Divicore entered into an employment letter agreement with
Mr. Wilde. The annual base salary for Mr. Wilde is $125,000 per annum. Under
the employment letter agreement, Divicore paid $25,000 to Mr. Wilde as a
signing bonus and granted to Mr. Wilde a stock option to purchase 166,667
shares of Divicore common stock at an exercise price of $6.00 per share. These
stock options have fully vested. These stock options were regranted on
September 23, 1998 at $2.52 per share. In addition, in the event of a sale of
all of the assets or a merger in which Divicore is not the surviving entity and
in which Divicore is valued at $80,000,000 or more, Mr. Wilde is entitled to
the greater of 2.5% of the proceeds or $2,000,000 in cash.
 
   In November 1997, Divicore entered into an employment agreement with Mr.
Harris, in which Divicore hired Mr. Harris as its Chief Technology Officer for
a two year term at a base salary of $125,000 per year, an annual cash bonus of
$35,000 and incentive stock options to purchase up to 4,167 shares of common
stock in minimum blocks of 2,083 shares at an exercise price of $1.50 per
share. In addition, if Mr. Harris is terminated for any reason other than gross
malfeasance or gross nonfeasance, he will be paid his then-current salary for
six additional months. Finally, if Mr. Harris is terminated, his options
immediately vest.
 
   In November 1997, Divicore entered into an employment agreement with Mr.
Liu, in which Divicore hired Mr. Liu as its Chief Financial Officer for a term
of two years at a base salary of $125,000 per year plus an annual cash bonus of
$35,000 and options to purchase up to 4,167 shares of common stock per year for
significant performance and an additional 2,083 shares of common stock for
exceptional performance. In addition, if Mr. Liu is terminated for any reason
other than gross malfeasance or gross nonfeasance, he will be paid his then-
current salary for six additional months.

cash bonus of $35,000, a commission in 1998 of three percent of the gross
contribution margin in excess of $9,236,000 and options to purchase up to
83,333 shares of common stock at an exercise price of $6.00 per share that
immediately vest upon a change of control or the resignation, termination or
demotion of Frank Wilde. In addition, Mr. Sharp may be awarded additional
options to purchase up to 4,167 shares of common stock per year for significant
performance and options to purchase up to an additional 2,083 shares of common
stock for exceptional performance. Finally, if Mr. Sharp is terminated for any
reason other than gross malfeasance or gross nonfeasance, he will be paid his
then-current salary for six additional months.
 
   In December 1997, Divicore entered into an employment agreement with Mr.
Russell, in which Divicore hired Mr. Russell as the Director of Engineering for
a two year term for a base salary of $125,000 per year, an annual cash bonus of
$35,000 per year and options to purchase up to 4,167 shares of common stock per
year for significant performance and an additional 2,083 shares of common stock
per year for exceptional performance. In addition, if Mr. Russell is terminated
for any reason other than gross malfeasance or gross nonfeasance, he will be
paid his then-current salary for six additional months.
 
   In February 1998, Divicore entered into an employment agreement with Mr.
Garnick, in which Divicore employed Mr. Garnick as Chairman of the Board and
Chief Executive Officer for an initial two year term commencing January 1, 1998
at a base salary of $125,000. In March 1998, this employment agreement was
amended, as a result of which Mr. Garnick resigned as Chief Executive Officer
but remained employed by Divicore and remained as a director. The amendment
provided that if Mr. Garnick was terminated by Divicore (other than for gross
malfeasance or gross non-feasance) or if he resigned his employment at Divicore
or if he were removed as Chairman of the Board, he would nonetheless remain a
director of Divicore until either a merger or an initial public offering of
Divicore stock.
 
   In April 1999, Divicore entered into a letter agreement with Gregg W.
Garnick, pursuant to which Mr. Garnick resigned as a director of Divicore and
agreed to enter into a consulting agreement to perform marketing and other
special projects for a term expiring on the earlier of one year or seven months
from the closing of this offering. In addition, Divicore accelerated 2,635 of
Mr. Garnick's unvested options.
 
Limitation of Liability and Indemnification
 
   Divicore's certificate of incorporation eliminates to the maximum extent
allowed by the Delaware General Corporation Law, subject to certain exceptions,
directors' personal liability to Divicore or its stockholders for monetary
damages for breaches of fiduciary duties. The certificate of incorporation does
not, however, eliminate or limit the personal liability of a director for the
following:
 
  .  any breach of the director's duty of loyalty to Divicore or its
     stockholders;
 
  .  acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of law;
 
  .  unlawful payments of dividends or unlawful stock repurchases or
     redemptions as provided in Section 174 of the Delaware General
     Corporation Law; or
 
  .  any transaction from which the director derived an improper personal
     benefit.
 
   Divicore's bylaws provide that Divicore shall indemnify its directors and
executive officers to the fullest extent permitted under the Delaware General
Corporation Law and may indemnify its other officers, employees and other
agents as set forth in the Delaware General Corporation Law. In addition,
Divicore has entered into an indemnification agreement with each of its
directors and officers. The indemnification agreements contain provisions that
require Divicore, among other things, to indemnify its directors and executive
officers against certain liabilities (other than liabilities arising from
intentional or knowing and culpable violations of law) that may arise by reason
of their status or service as directors or executive officers of Divicore or
other entities to
 
                                       63
<PAGE>
 
which they provide service at the request of Divicore and to advance expenses
they may incur as a result of any proceeding against them as to which they
could be indemnified. Divicore believes that these bylaw provisions and
indemnification agreements are necessary to attract and retain qualified
directors and officers. Prior to the consummation of the offering, Divicore
will obtain an insurance policy covering directors and officers for claims they
may otherwise be required to pay or for which Divicore is required to indemnify
them, subject to certain exclusions.
 
   At present, there is no pending litigation or proceeding involving a
director, officer, employee or agent of Divicore where indemnification will be
required or permitted, and Divicore is not aware of any threatened litigation
or proceeding which may result in a claim for indemnification.

                              CERTAIN TRANSACTIONS
 
Sales of Securities
 
   Since January 1996, Divicore has raised capital primarily through the sale
of its securities, including:
 
    .  In March 1996, Divicore sold a combination of subordinated notes and
       warrants to purchase an aggregate of 83,635 shares of Class A
       Preferred Stock at an exercise price of $0.746352 per share to NEPA
       Venture Fund II, L.P. for an aggregate consideration of $125,000.
 
    .  In March 1998, Divicore entered into a Development and License
       Agreement with ATI Technologies, Inc. whereby Divicore agreed to
       allow ATI Technologies to convert up to $125,000 in prospective
       royalty payments due to Divicore per quarter in each of the first
       four quarters of royalty payments and $500,000 in the fourth quarter
       of the second year of royalty payments into 200,803 shares of Class
       B Preferred Stock and warrants to purchase 81,727 shares of common
       stock at an exercise price of $0.06 per share.
 
    .  In December 1997 and March 1998, Divicore borrowed $1,770,000 from
       Atlantic Coastal Ventures L.P. pursuant to 6% convertible
       subordinated debentures due March and May 1998. In April 1998,
       Atlantic Coastal Ventures received interest on the debentures in the
       form of common stock and exercised warrants received with the
       debentures for 208,682 shares of common stock. In addition, Atlantic
       Coastal Ventures converted the debentures into 355,422 shares of
       Class B Preferred Stock.
 
    .  In April 1998, Divicore sold to various investors including entities
       affiliated with Patricof & Co. Ventures, Inc. and Atlantic Coastal
       Ventures an aggregate of 3,226,908 shares of Class B Preferred Stock
       and warrants to purchase 1,313,351 shares of its common stock at an
       exercise price of $.06 per share for an aggregate consideration of
       $16,070,000.
 
    .  In May 1998, Divicore sold to ATI Technologies an aggregate of
       502,008 shares of Class B Preferred Stock and warrants to purchase
       204,317 shares of common stock at $0.06 per share for an aggregate
       consideration of $2,500,000.
 
   The following table summarizes the shares of common stock, preferred stock
and warrants purchased by Divicore's executive officers, directors and 5%
percent stockholders and persons associated with them since January 1996. The
number of total shares on an as-converted basis reflects a one-to-one
conversion to common stock ratio for each share of Class A and Class B
Preferred Stock.

Agreements with Officers and Directors
 
   Messrs. Vais and Threadgill are on the board of directors pursuant to
agreements with Divicore.
 
   In March 1996, Divicore entered into a series of salary deferral
transactions with each of Gregg W. Garnick, Jason C. Liu and Robert S. Russell,
whereby in exchange for salary deferral, each officer received non-plan stock
options to purchase 50,510 shares of common stock at an exercise price of $0.60
per share.
 
                                       65
<PAGE>
 
   In April 1998, Divicore repurchased 200,000 shares of Divicore common stock
from Gregg W. Garnick, at a price of $3.60 per share for an aggregate
consideration of $720,000.
 
   In September 1998, Divicore entered into an agreement with Michael Harris
and Brenda Harris in which the Harrises borrowed $60,000 payable in three years
with no interest accruing in those three years. In addition, if Mr. Harris
achieves each of his quarterly performance goals with Divicore, at the end of
each year, Divicore will forgive one-third of the principal amount. If Mr.
Harris voluntarily leaves or is terminated for cause, the note is immediately
due and payable. However, if Divicore completes an initial public offering of
its stock, Divicore will completely forgive the note. The parties also entered
into an agreement confirming that the note is immediately payable upon
termination and that the outstanding principal will be forgiven upon an initial
public offering of Divicore common stock.
 
Agreement with ATI Technologies Inc.
 
   In March 1998, Divicore entered into a Development and License Agreement
with ATI Technologies for a term of two years, and extendable for one year
terms thereafter, pursuant to which Divicore granted a worldwide, non-exclusive
license to ATI Technologies to Divicore's Software DVD, Video Encoder Software,
and Hardware DVD technology in exchange for a royalty for each copy of Video
Encoder Software sold by ATI Technologies. ATI Technologies agreed to pay to
Divicore a minimum quarterly royalty payment; however, ATI Technologies is
allowed to convert up to $125,000 of prospective quarterly royalty payments in
each of the first four quarters of royalty payments and $500,000 of prospective
quarterly royalty payments in the fourth quarter of the second year of royalty
payments into shares of Class B Preferred Stock and warrants to purchase common
stock. This agreement may be terminated by either party for a material breach
of the agreement or for a repeated breach of the agreement subject to certain
notice requirements. In April 1999, Divicore issued 25,100 shares of Class B
Preferred Stock and warrants to purchase 10,216 shares of common stock under
this agreement. Also in April 1999, Divicore amended the agreement to terminate
ATI Technology's right to receive Class B Preferred Stock and warrants and
issued to ATI Technologies 100,402 shares of Class B Preferred Stock and
warrants to purchase 40,863 shares of common stock in exchange for which
Divicore received promissory notes with an aggregate value of $500,000.
 
Other Related Party Transactions
 
   Divicore has entered into employment agreements with its executive officers.
See "Management--Employment Contracts, Termination of Employment and Change in
Control Arrangements."
 
   Holders of shares of preferred stock are entitled to certain registration
rights in respect of the common stock issued or issuable upon conversion
thereof. See "Description of Capital Stock--Registration Rights."
 
   Divicore has also granted additional options and issued common stock to
certain of its executive officers and directors. See "Management--Director
Compensation," and "Principal Stockholders."
 
   Divicore has entered into an Indemnification Agreement with each of its
executive officers and directors containing provisions that may require it,
among other things, to indemnify its officers and directors against certain
liabilities that may arise by reason of their status or service as officers or
directors (other than liabilities arising from willful misconduct of a culpable
nature) and to advance expenses incurred as a result of any proceeding against
them as to which they could be indemnified. See "Management--Limitation on
Liability and Indemnification Matters."
 
   Divicore has entered into non-competition and confidentiality agreements
with certain of its officers.
 
   Divicore believes that all of the transactions set forth above were made on
terms no less favorable to Divicore than could have been otherwise obtained
from unaffiliated third parties. All future transactions, including loans, if
any, between Divicore and its officers, directors and principal stockholders
and their
 
                                       66

affiliates and any transactions between Divicore and any entity with which its
officers, directors or 5% stockholders are affiliated will be approved by a
majority of the board of directors, including a majority of the independent and
disinterested outside directors of the board of directors and will be on terms
no less favorable to Divicore than could be obtained from unaffiliated third
parties.

                          DESCRIPTION OF CAPITAL STOCK
 
   At the closing of this offering, the authorized capital stock of Divicore
will consist of 50,000,000 shares of common stock, $.001 par value, and
5,000,000 shares of preferred stock, $.001 par value, covered by the
assumptions contained in the summary. An aggregate of        shares of common
stock will be issued and outstanding, excluding shares issued upon exercise of
outstanding options and warrants. No shares of preferred stock will be issued
and outstanding.
 
Common Stock
 
   The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may
be applicable to any outstanding preferred stock that may come into existence,
the holders of common stock are entitled to receive ratably those dividends, if
any, as may be declared from time to time by the board of directors out of
funds legally available for dividends. See "Dividend Policy." In the event of
liquidation, dissolution or winding up of Divicore, the holders of common stock
are entitled to share ratably in all assets remaining after payment of
liabilities, subject to prior distribution rights of preferred stock, if any,
then outstanding. The common stock has no preemptive or conversion rights or
other subscription rights. There are no redemption or sinking fund provisions
applicable to the common stock. All outstanding shares of common stock are
fully paid and nonassessable, and the shares of common stock to be outstanding
upon completion of this offering will be fully paid and nonassessable.
 
Preferred Stock
 
   Divicore's board of directors is authorized to issue from time to time,
without stockholder authorization, in one or more designated series, any or all
of the authorized but unissued shares of preferred stock of Divicore with any
dividend, redemption, conversion and exchange provisions as may be provided in
the particular series. Any series of preferred stock may possess voting,
dividend, liquidation and redemption rights superior to that of the common
stock. The rights of the holders of common stock will be subject to, and may be
adversely affected by, the rights of the holders of any preferred stock that
may be issued in the future. Issuance of a new series of preferred stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of entrenching Divicore's board
of directors and making it more difficult for a third party to acquire, or
discourage a third party from acquiring, a majority of the outstanding voting
stock of Divicore. Divicore has no present plans to issue any shares of or
designate any series of preferred stock.
 
Warrants
 
   At March 31, 1999, there were warrants outstanding to purchase a total of
1,608,172 shares of common stock on an as-converted basis, including:
 
    .  Warrants to purchase 34,970 and 20,982 shares of common stock at
       $0.7473 per share, which will expire in June 2003 and November 2003,
       respectively.
 
    .  Warrants to purchase 12,500, 33,333 and 16,667 shares of common
       stock at $3.558 per share, which will expire in June 2004, January

    .  Warrants to purchase 1,376,452, 40,864, 10,216, 10,216 and 10,216

       April 2003, May 2003, July 2003, September 2003 and December 2003,
       respectively.
 
    .  Warrants to purchase 3,333 shares of common stock at $6.00 per

Registration Rights
 
   Upon completion of the offering, the holders of an aggregate of
approximately 5,961,046 shares of common stock and the holders of warrants to
purchase up to approximately 1,608,172 shares of common stock will be entitled
to certain rights with respect to the registration of such shares under the
Securities Act of 1933, as amended, or the Securities Act. Under the terms of
the registration rights agreements, if Divicore proposes to register any of its
securities under the Securities Act, either for its own account or for the
account of other security holders exercising registration rights, these holders
are entitled to notice of such registration and are entitled to include shares
of common stock in the registration. The rights are subject to conditions and
limitations, among them the right of the underwriters of an offering subject to
the registration to limit the number of shares included in such registration.
Holders of these rights may also require Divicore to file a registration
statement under the Securities Act of 1933 at its expense with respect to their
shares of common stock, and Divicore is required to use its best efforts to
effect such registration, subject to conditions and limitations. Furthermore,
stockholders with registration rights may require Divicore to file additional
registration statements on Form S-3, subject to conditions and limitations.
 
Antitakeover Effects of Provisions of the Certificate of Incorporation, Bylaws
and Delaware Law
 
   Divicore's certificate of incorporation authorizes the board to establish
one or more series of undesignated preferred stock, the terms of which can be
determined by the board at the time of issuance without stockholder action. See
"--Preferred Stock." The certificate of incorporation also provides that all
stockholder action must be effected at a duly called meeting of stockholders
and not by written consent. In addition, the certificate of incorporation and
bylaws do not permit stockholders of Divicore to call a special meeting of
stockholders. Only Divicore's Board of Directors are permitted to call a
special meeting of stockholders. The certificate of incorporation also provides
that the Board of Directors is divided into three classes, with each director
assigned to a class with a term of three years, and that the number of
directors may only be determined by the board of directors. The bylaws also
require that stockholders give advance notice to Divicore's Secretary of any
nominations for director or other business to be brought by stockholders at any
stockholders' meeting, and that the Chairman has the authority to adjourn any
such meeting. The bylaws also require a supermajority vote of members of the
Board of Directors and/or stockholders to amend certain bylaw provisions. These
provisions of the restated certificate of incorporation and the bylaws could
discourage potential acquisition proposals and could delay or prevent a change
in control of Divicore. These provisions also may have the effect of preventing
changes in the management of Divicore. See "Risk Factors--We have adopted
certain anti-takeover provisions."
 
   Divicore is subject to Section 203 of the Delaware General Corporation Law,
which, subject to certain exceptions, prohibits a Delaware corporation from
engaging in any business combination with any interested stockholder for a
period of three years following the date that the stockholder became an
interested stockholder, unless:
 
    .  prior to that date, the board of directors of the corporation
       approved either the business combination or the transaction that
       resulted in the stockholder becoming an interested stockholder;
 
    .  upon consummation of the transaction that resulted in the
       stockholder becoming an interested stockholder, the interested
       stockholder owned at least 85% of the voting stock of the
       corporation outstanding at the time the transaction commenced,
       excluding for purposes of determining the number of shares
       outstanding those shares owned:
 
      .  by persons who are directors and also officers; and
 
      .  by employee stock plans in which employee participants do not
         have the right to determine confidentially whether shares held
         subject to the plan will be tendered in a tender or exchange
         offer; or
 
                                       71
<PAGE>
 
    .  on or subsequent to that date, the business combination is approved
       by the board of directors of the corporation and authorized at an
       annual or special meeting of stockholders, and not by written
       consent, by the affirmative vote of at least 66 2/3% of the
       outstanding voting stock that is not owned by the interested
       stockholder.
 
   Section 203 defines "business combination" to include the following:
 
    .  any merger or consolidation involving the corporation and the
       interested stockholder;
 
    .  any sale, transfer, pledge or other disposition of 10% or more of
       the assets of the corporation involving the interested stockholder;
 
    .  subject to certain exceptions, any transaction that results in the
       issuance or transfer by the corporation of any stock of the
       corporation to the interested stockholder;
 
    .  any transaction involving the corporation that has the effect of
       increasing the proportionate share of the stock of any class or
       series of the corporation beneficially owned by the interested
       stockholder; or
 
    .  the receipt by the interested stockholder of the benefit of any
       loans, advances, guarantees, pledges or other financial benefits
       provided by or through the corporation.
 
   In general, section 203 defines an interested stockholder as any entity or
person beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by any of these entities or persons.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   Prior to this offering, there has not been any public market for the common
stock. Future sales of substantial amounts of common stock (including shares
issued upon exercise of outstanding options or warrants) in the public market
could adversely affect prevailing market prices from time to time. Furthermore,
since only a limited number of shares will be available for sale shortly after
this offering because of certain contractual and legal restrictions on resale
(as described below), sales of substantial amount of common stock in the public
market after the restrictions lapse could adversely affect the prevailing
market price and the ability of Divicore to raise equity capital in the future.
 
   Upon completion of this offering, Divicore will have             shares of
common stock outstanding assuming no exercise of options and warrants after
March 31, 1999. Of the total outstanding shares of common stock, the
            shares sold in this offering will be freely tradable without
restriction or further registration under the Securities Act, except that any
shares purchased by "affiliates" of Divicore, as that term is defined in
Rule 144 under the Securities Act, may generally only be sold pursuant to an
effective registration statement under the Securities Act or in compliance with
the limitations of Rule 144 as described below.
 
   The remaining              shares of common stock are "restricted
securities" as that term is defined in Rule 144. The restricted shares will be
available for sale in the public market following the expiration of the 180 day
lock-up agreement further described below. In addition, the holders of warrants
for 1,659,251 shares of common stock can exercise these warrants at any time,
but these shares cannot be sold until the expiration of the 180 day lockup
period following the date of this prospectus. Upon expiration of these
agreements, approximately           shares (including shares issuable upon
exercise of warrants) will be eligible for immediate resale in the public
market subject to the volume and other limitations of Rule 144, and
approximately     shares will be eligible for immediate resale pursuant to Rule
144(k) without such limitations, unless they are held by affiliates of
Divicore. Beginning 180 days after the date of this prospectus the holders of
               restricted shares and the holders of warrants for 1,659,251
shares of common stock are entitled to certain rights with respect to
registration of these shares for sale in the public market. If these holders
sell in the public market these sales would have a material adverse effect on
the market price of the common stock.
 
   All of the officers and directors and substantially all of the
securityholders of Divicore have entered into contractual "lock-up" agreements
generally providing that, subject to certain limited exceptions, they will not
offer, pledge, sell, offer to sell, contract to sell, sell any option or
contract to purchase, purchase any option to sell, grant any option, right or
warrant to purchase, or otherwise transfer or dispose of, directly or
indirectly, any of the shares of common stock or any securities convertible
into, or exercisable or exchangeable for, common stock owned by them, or enter
into any swap or other arrangement that transfers to another, in whole or in
part, any of the economic consequences of ownership of the common stock, for a
period of 180 days after the date of this prospectus, without the prior written
consent of Bear, Stearns & Co. Inc. subject to certain limited exceptions.
Bear, Stearns & Co. may, in its sole discretion and at any time without notice,
release all or any portion of the securities subject to lock-up agreements.
When determining whether or not to release shares from the lock-up agreements,
Bear, Stearns & Co. will consider, among other factors, the stockholder's
reasons for requesting the release, the number of shares for which the release
is being requested and market conditions at the time. Following the expiration
of the 180-day lock-up period, all              shares of common stock will be
available for sale in the public market subject to compliance with Rule 144 or
Rule 701.
 
   In general, under Rule 144 as currently in effect, an affiliate of Divicore
or a person (or persons whose shares are aggregated) who has beneficially owned
restricted shares for at least one year, (including the holding period of any
prior owner other than a person who may be deemed an affiliate of Divicore) is
entitled to sell within any three-month period a number of shares of common
stock that does not exceed the greater of 1% of the then-outstanding shares of
common stock (approximately         shares after giving effect to this
offering) and the average weekly trading volume of the common stock on The
Nasdaq National Market during the four calendar weeks preceding the filing of a
Form 144 notice with respect to this sale. Sales under
 
                                       73
<PAGE>
 
Rule 144 of the Securities Act are subject to certain restrictions relating to
manner of sale, notice and the availability of current public information about
Divicore. Under Rule 144(k), a person who is not an affiliate of Divicore at
any time during the ninety days preceding a sale, and who has beneficially
owned shares for at least two years (including the holding period of any prior
owner other than a person who may be deemed an affiliate of Divicore), would be
entitled to sell these shares immediately following this offering without
regard to the volume limitations, manner of sale provisions or notice or other
requirements of Rule 144 of the Securities Act. However, the transfer agent may
require an opinion of counsel that a proposed sale of shares comes within the
terms of Rule 144 of the Securities Act prior to effecting a transfer of these
shares.
 
   Divicore intends to file, after consummation of this offering, a
registration statement on Form S-8 under the Securities Act covering all shares
of common stock reserved for issuance under its 1999 Stock Incentive Plan and
its 1999 Employee Stock Purchase Plan. See "Management-Benefit Plans." Any
shares registered under such registration statement would be available for sale
in the open markets in the future unless these shares are subject to vesting
restrictions with Divicore or the contractual restrictions described above.

</TABLE>
 
   The nature of the respective obligations of the underwriters is such that
all of the shares of common stock (other than shares of common stock covered by
the over-allotment option described below) must be purchased if any are
purchased. Those obligations are subject, however, to various conditions,
including the approval of certain matters by counsel. Divicore has agreed to
indemnify the underwriters against certain liabilities, including liabilities
under the Securities Act, and, where such indemnification is unavailable, to
contribute to payments that the underwriters may be required to make in respect
of such liabilities.
 
   Divicore has been advised that the underwriters propose to offer the shares
of common stock directly to the public initially at the public offering price
set forth on the cover page of this Prospectus and to certain selected dealers
at such price less a concession not to exceed $      per share, that the
underwriters may allow, and such selected dealers may reallow, a concession to
certain other dealers not to exceed $     per share and that after the
commencement of this offering, the public offering price and the concessions
may be changed. The common stock is offered subject to receipt and acceptance
by the underwriters, and to various other conditions, including the right to
reject orders in whole or in part. The representatives of the underwriters have
advised Divicore that the underwriters do not expect to confirm sales to any
accounts over which they exercise discretionary authority.
 
   Divicore has granted to the underwriters an option to purchase in the
aggregate up to              additional shares of common stock to be sold in
this offering solely to cover over-allotments, if any. The option may be
exercised in whole or in part at any time within 30 days after the date of this
prospectus. To the extent the option is exercised, the underwriters will be
severally committed, subject to certain conditions, including the approval of
certain matters by counsel, to purchase the additional shares of common stock
in proportion to their respective purchase commitments as indicated in the
preceding table.
 
   The following table shows the per share and total underwriting discounts and
commission to be paid to the underwriters by Divicore. These amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase additional shares.

   The underwriters have reserved for sale at the initial public offering price
up to 5% of the number of shares of common stock offered hereby for sale to
certain directors, officers, other employees, business affiliates and related
persons of Divicore who have expressed an interest in purchasing shares. The
number of shares available for sale to the general public will be reduced to
the extent any reserved shares are purchased. Any reserved shares not so
purchased will be offered by the underwriters on the same basis as the other
shares offered hereby.
 
   Divicore, its executive officers, directors and substantially all of its
securityholders have agreed that, subject to certain limited exceptions, for a
period of 180 days after the date of this prospectus, without the prior written
consent of Bear, Stearns & Co. Inc., they will not:
 
    .  directly or indirectly, issue, sell, offer or agree to sell or
       otherwise dispose of any shares of Divicore common stock (or
       securities convertible into, exchangeable for or evidencing the
       right to purchase shares of common stock);
 
    .  nor enter into any swap or any other agreement or any transaction
       that transfers, in whole or in part, directly or indirectly, the
       economic consequence of Divicore ownership of Divicore common stock,
       whether any such swap transaction is to be settled by delivery of
       common stock or other securities, in cash or otherwise, or exercise
       their rights, as applicable, to require Divicore to register common
       stock.
 
   The restrictions described in the previous paragraph do not apply to:
 
    .  transactions by any person other than Divicore relating to shares of
       common stock or other securities acquired in open market
       transactions after the completion of this offering; or
 
    .  certain specified transfers, provided that, following such
       transfers, the transferees are subject to transfer restrictions
       similar to those described above.
 
   Prior to this offering, there has been no public market for the common
stock. Consequently, the initial public offering price will be determined
through negotiations among Divicore and the representatives of the
underwriters. Among the factors considered in making such determination were
Divicore's financial and operating history and condition, market valuations of
other companies engaged in activities similar to Divicore's, Divicore's
prospects and prospects for the industry in which it does business in general,
the management of Divicore, prevailing equity market conditions and the demand
for securities considered comparable to those of Divicore.
 
   In order to facilitate this offering, certain persons participating in this
offering may engage in transactions that stabilize, maintain or otherwise
affect the price of the common stock during and after this offering.
Specifically, the underwriters may over-allot or otherwise create a short
position in the common stock for their own account by selling more shares of
common stock, than have been sold to them by Divicore. The underwriters may
elect to cover any such short position by purchasing shares of common stock in
the open market or by exercising the over-allotment option granted to the
underwriters. In addition, the underwriters may stabilize or maintain the price
of the common stock by bidding for or purchasing shares of common stock in the
open market and may impose penalty bids, under which selling concessions
allowed to syndicate members or other broker-dealers participating in this
offering are reclaimed if shares of common stock previously distributed in this
offering are repurchased in connection with stabilization transactions or
otherwise. The effect of these transactions may be to stabilize or maintain the
market price of the common stock at a level above that which might otherwise
prevail in the open market. The imposition of a penalty bid may also affect the
price of the common stock to the extent that it discourages resales thereof. No
representation is made as to the magnitude or effect of any such stabilization
or other transactions. Such transactions may be effected on the Nasdaq National
Market or otherwise and, if commenced, may be discontinued at any time.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders
Divicore Inc.:
 
   We have audited the accompanying consolidated balance sheets of Divicore
Inc. and subsidiaries as of December 31, 1997 and 1998, and the related
consolidated statements of operations, changes in stockholders' deficiency, and
cash flows for each of the years in the three-year period ended December 31,
1998. 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Divicore
Inc. and subsidiaries as of December 31, 1997 and 1998, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1998, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
       (Information with respect to March 31, 1998 and 1999 is unaudited)
 
(1) Summary of Significant Accounting Policies
 
  (a) Description of Business
 
   Divicore Inc. (the Company), which is in the process of changing its name
from Quadrant International, Inc., effective May 1999, designs, develops,
licenses and markets core-based modular software solutions that enable digital
video and audio stream management in personal computer systems and consumer
electronic devices. The Company also provides supporting hardware designs to
selected customers as well as customization services and customer support. The
Company's solutions enable decoding (playback) and encoding (recording) of
multimedia formats such as digital versatile disk (DVD); direct broadcast
satellite (DBS) and high-definition television (HDTV) on existing personal
computers and consumer electronics platforms. The Company's customers consist
principally of personal computer and consumer electronics manufacturers.
 
   Through 1998 the Company's revenue was substantially generated from selling
hardware-based digital video solutions to personal computer and consumer
electronics manufacturers and through wholesale distributors. The Company has
recently changed its strategic focus from selling a hardware-based digital
video solution to licensing its proprietary technology to provide software-
based digital video solutions to primarily personal computer and consumer
electronics original equipment manufacturers.
 
   The Company was incorporated in Pennsylvania in April 1994.
 
   The Company has sustained significant net losses and negative cash flows
from operations since its inception. The Company's ability to meet its
obligations in the ordinary course of business is dependent upon its ability to
establish profitable operations or raise additional financing through public or
private equity financing, bank financing, or other sources of capital. During
1998, the Company sold approximately $18.6 million of its preferred stock.
Management believes that its current funds combined with other available
sources of funding will be sufficient to enable the Company to meet its planned
expenditures through at least December 31, 1999. The Company may require
additional capital to finance its future operations and fund its ongoing
research and development activities beyond 1999. Additional financing may not
be available when needed and, if such financing is available, it may not be
available on terms favorable to the Company.
 
  (b) Unaudited Interim Financial Information
 
   The interim consolidated financial statements of the Company for the three
months ended March 31, 1998 and 1999, included herein have been prepared by the
Company, without audit, pursuant to the rules and regulations of the Securities
and Exchange Commission (SEC). Certain information and footnote disclosures
normally included in financial statements prepared in accordance with generally
accepted accounting principles have been condensed or omitted pursuant to such
rules and regulations relating to interim financial statements. In the opinion
of management, the accompanying unaudited interim consolidated financial
statements reflect all adjustments, consisting only of normal recurring
adjustments, necessary to present fairly the financial position of the Company
at March 31, 1999, and the results of its operations and its cash flows for the
three months ended March 31, 1998 and 1999.
 
  (c) Principles of Consolidation
 
   The consolidated financial statements include the financial statements of
the Company and its wholly owned subsidiaries. All significant intercompany
balances and transactions have been eliminated in consolidation.

       (Information with respect to March 31, 1998 and 1999 is unaudited)
 
 
  (d) Cash and Cash Equivalents
 
   For purposes of the statement of cash flows, the Company considers all
highly liquid instruments purchased with an original maturity of three months
or less to be cash equivalents.
 
  (e) Inventory
 
   Inventory, which principally consists of finished goods, is valued at the
lower of cost or market. Cost is determined using the first-in, first-out
method (FIFO). Inventory is net of reserves of approximately $400,000 and
$174,000 at December 31, 1997 and 1998, respectively.
 
  (f) Furniture and Equipment
 
   Furniture and equipment are stated at cost. Equipment under capital leases
is stated at the present value of the minimum lease payments. Depreciation and
amortization is calculated on the straight-line method over the estimated
useful lives of the assets as follows:
 
<TABLE>
       <S>                                                               <C>
       Purchased software............................................... 5 years
       Computer equipment............................................... 5 years
       Research and development equipment............................... 5 years
       Furniture and fixtures........................................... 7 years
</TABLE>
 
  (g) Goodwill and Other Intangibles
 
   Goodwill and other intangibles are amortized using the straight-line method
from the date of acquisition over the expected period to be benefited,
estimated at four years. The Company assesses the recoverability of goodwill,
as well as other long-lived assets, based upon expectations of future
undiscounted cash flows in accordance with Statement of Financial Accounting
Standards (SFAS) No. 121, Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of.
 
  (h) Deferred Offering Costs
 
   As of March 31, 1999, specific incremental costs directly attributable to
the planned initial public offering process have been deferred. These costs
will be charged against additional-paid-in-capital in connection with the
consummation of this offering.
 
  (i) Revenue Recognition
 
   Licensing revenues for one-time license fees are recognized in the period in
which the license agreement is signed, delivery of the technology has occurred
and collectibility is probable. Licensing revenues associated with ongoing
licensing agreements are recognized when earned, which is generally based on
receiving notification from licensees stating the number of products sold which
incorporate the licensed technology from the Company and for which license fees
are due.
 
   Revenue is recognized upon shipment of products to customers. An allowance
for returned merchandise is provided based on the Company's historical
experience. Revenue related to services are recognized upon delivery of the
service in the case of time and material contracts. Revenue related to
development contracts involving significant modifications or customization of
hardware or software under unilateral or joint development arrangements is
recognized using the percentage-of-completion method, based on performance
milestones specified in the contract where such milestones fairly reflect
progress toward contract completion. In other instances, progress toward
completion is based on individual contract costs incurred to date compared with
total estimated contract costs. Losses on contracts are recognized when the
loss is apparent.

       (Information with respect to March 31, 1998 and 1999 is unaudited)
 
 
   Other income represents amounts received in connection with the cancellation
of a development project by a customer during 1997. A total of approximately
$1,134,000 was received from the customer, of which approximately $418,000 was
recorded as revenue based on costs of revenue incurred. The remaining
approximately $716,000 was recorded in other income as a cancellation fee.
 
  (j) Research and Development Costs
 
   Research and development costs are expensed as incurred.
 
  (k) Income Taxes
 
   In September 1996, the stockholders elected "C" corporation status for
federal and state income tax purposes. Effective with this election, income
taxes are accounted for in accordance with SFAS No. 109, Accounting for Income
Taxes. Under the asset and liability method of SFAS No. 109, deferred tax
assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carry forwards.
 
  (l) Financial Instruments
 
   The Company's financial instruments principally consist of cash, accounts
receivable, accounts payable, loans payable and capital lease obligations that
are carried at cost which approximates fair value.
 
  (m) Stock Options
 
   In 1996, the Company adopted SFAS No. 123, Accounting for Stock-based
Compensation, which provides the alternative to adopt the fair value method for
expense recognition of employee stock options and stock-based awards or to
continue to account for such items using the intrinsic value method as outlined
under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued
to Employees (APB 25) with pro forma disclosures of results of operations as if
the fair value method had been applied. The Company has elected to continue to
apply APB 25 for stock options and stock-based awards to employees and has
disclosed pro forma net loss as if the fair value method had been applied (note
12).
 
  (n) Use of Estimates
 
   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  (o) Long-Lived Assets
 
   The Company reviews long-lived assets and certain identifiable intangibles
to be held and used by an entity for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable.
 
  (p) Foreign Currency Translation
 
   All assets and liabilities of foreign subsidiaries are translated into U.S.
dollars at fiscal year-end exchange rates. Income and expense items are
translated at average exchange rates prevailing during the fiscal year. The
 
                                      F-9

       (Information with respect to March 31, 1998 and 1999 is unaudited)
 
resulting translation adjustments are recorded as a component of stockholders'
deficiency in the accompanying consolidated financial statements.
 
  (q) Comprehensive Income
 
   In June 1997, the FASB issued SFAS No. 130, Reporting Comprehensive Income,
which establishes standards for reporting and display of comprehensive income
and its components in the financial statements. SFAS No. 130 is effective for
fiscal years beginning after December 15, 1997. Reclassification of financial
statements for earlier periods provided for comparative purposes is required.
The Company adopted SFAS No. 130 during 1998.
 
  (r) Computation of Historical Net Loss Per Share and Pro Forma Net Loss Per
 Share
 
   The Company computes earnings per share in accordance with SFAS No. 128,
Computation of Earnings Per Share. In accordance with SFAS No. 128, basic
earnings per share is computed using the weighted average number of common
shares outstanding during the period. Dilutive earnings per share is computed
using the weighted average number of common and dilutive common equivalent
shares outstanding during the period. Common equivalent shares consist of the
incremental common shares issuable upon the exercise of stock options and
warrants (using the treasury stock method), and the incremental common shares
issuable upon the conversion of the convertible preferred stock (using the if-
converted method). Common equivalent shares are excluded from the calculation
if their effect is anti-dilutive. Pursuant to SEC Staff Accounting Bulletin No.
98, common stock and convertible preferred stock issued for nominal
consideration, prior to the anticipated effective date of an IPO, are required
to be included in the calculation of basic and diluted net loss per share, as
if they were outstanding for all periods presented. To date, the Company has
not had any issuances or grants for nominal consideration.
 
   Pro forma net loss per share is computed using the weighted average number
of shares of common stock outstanding, including common equivalent shares from
the convertible preferred stock (using the if-converted method), which will
automatically convert into common stock upon an IPO as if converted at the
original date of issuance, for both basic and diluted net loss per share, even
though inclusion is anti-dilutive.

  (s) Recent Accounting Pronouncements
 
   In March 1998, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position 98-1, Accounting for the Cost of Computer
Software Developed or Obtained for Internal Use (SOP 98-1). SOP 98-1 is
effective for financial statements for the years beginning after December 15,
1998. SOP 98-1 provides guidance over accounting for computer software
developed or obtained for internal use including the requirement to capitalize
specified costs and amortization of such costs. The adoption of this standard
did not have a material effect on the Company's capitalization policy.
 
   In April 1998, the AICPA issued Statement of Position 98-5, Reporting on the
Costs of Start-Up Activities (SOP 98-5). SOP 98-5, which is effective for
fiscal years beginning after December 15, 1998, provides guidance on the
financial reporting of start-up costs and organization costs. It requires costs
of start up activities and organization costs to be expensed as incurred. As
the Company has expensed these costs historically, the adoption of this
standard did not have an impact on the Company's results of operations,
financial position or cash flows.
 
   In June 1998, the FASB issued SFAS No. 133, Accounting for Derivatives and
Hedging Activities, which establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives) and for hedging
activities. SFAS No. 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. As the Company does not currently engage or plan
to engage in derivative or hedging activities there will be no impact to the
Company's results of operations, financial position or cash flows upon the
adoption of this standard.
 
   In December 1998, the AICPA issued SOP 98-9, Modification of SOP 97-2,
Software Revenue Recognition, with respect to Certain Transactions. SOP 98-9
amends SOP 97-2 and SOP 98-4 extending the deferral of the application of
certain provisions of SOP 97-2 amended by SOP 98-4 through fiscal years

beginning on or before March 15, 1999. All other provisions of SOP 98-9 are
effective for transactions entered into in fiscal years beginning after March
15, 1999. The Company does not expect the adoption of SOP 98-9 to have a
material effect on its financial condition or results of operations.

(4) Acquisition
 
   In April 1998, the Company completed the acquisition of Viona Development
Hard & Software Engineering GmbH (Viona) a company located in Karlsruhe,
Germany specializing in the development of digital video technology.
 
   The Company paid a total of $11.4 million consisting of: $5.8 million in
cash, of which $2.6 million was paid at closing, $2.1 million will be paid
during 1999, and $1.35 million, recorded at a discounted value of $1.1 million,
will be paid in equal installments at the end of each of the next three fiscal
years; issued 1,204,820 shares of the Company's common stock valued at $4.8
million; and incurred transaction costs of $0.8 million.

   The acquisition of Viona was recorded under the purchase method of
accounting. The results of operations of Viona have been included in the
Company's consolidated financial statements from April 1, 1998. A portion of
the purchase price was allocated to in-process research and development
technology, which resulted in a charge of approximately $7.9 million to the
Company's operations in April 1998. At the date of acquisition, Viona had five
development projects that had not reached technological feasibility and for
which there was no alternative future use. The in-process research and
development technology was valued using a cash flow model, under which
projected income and expenses attributable to the purchased technology were
identified, and potential income streams were discounted using a 30%-35%
discount rate for risks, probabilities and uncertainties, including the stage
of development of the technology, viability of target markets and other
factors. The five development projects ranged in percentage of completion at
the date of acquisition from 5% to 80%.
 
   The excess of the purchase price over the fair value of the net identifiable
assets and in-process research and development technology acquired of $3.5
million has been recorded as goodwill and other intangibles and is amortized on
a straight-line basis over four years.
 
   The purchase price was allocated as follows (in thousands):

(5) Bank Line of Credit
 
   In June 1997 the Company refinanced its line of credit with a bank to an
aggregate amount of $1 million, subject to certain borrowing limitations based
on accounts receivable and inventory. The line of credit charged interest at
the prime rate plus 2% (10.5% at December 31, 1997) and was secured by
substantially all the assets of the Company. The bank was provided warrants
(note 12) to acquire 45,833 shares of the Company's common stock at an exercise
price of $3.56 per share. The estimated fair value of the warrants issued was
$33,964 and has been recorded as debt issuance costs. This amount was amortized
over the term of the line of credit. The line of credit required the Company,
among other things, to maintain certain financial ratios,

minimum working capital and tangible net worth on a quarterly basis. The
Company was not in compliance with these covenants at December 31, 1997. In
April 1998, the Company received a waiver of these covenant violations from the
bank and issued warrants to the bank to acquire 16,667 shares of the Company's
common stock at an exercise price of $3.56 per share. The estimated fair value
of the warrants issued is $22,600 and has been recorded as interest expense.
 
   In July 1998, the Company executed a Loan and Security Agreement (the Loan
Agreement) with a commercial bank that provides the Company a line of credit
(the Credit Line) in the amount of the lesser of $5 million or the borrowing
base, as defined, (principally limited to a percentage of eligible accounts
receivable and eligible inventory). The Credit Line provides for the Company to
issue a maximum of $2 million in the form of letters of credit which reduces
the amount of available borrowings under the Credit Line. The Credit Line
matures in July 2000 and bears interest at the prime rate plus 1% (8.75% at
December 31, 1998). The Credit Line is collateralized by substantially all of
the assets of the Company. The Company is required to comply with a tangible
net worth covenant, as defined in the Loan Agreement, and was not in compliance
with this covenant at December 31, 1998 and March 31, 1999. The Company
received a waiver of this covenant violation in April 1999. There was no amount
and approximately $1,252,000 outstanding under the Credit Line at December 31,
1998 and March 31, 1999, respectively, and approximately $3,510,000 and
$1,696,000 was available under the terms of the Credit Line at December 31,
1998 and March 31, 1999, respectively.
 
   At December 31, 1998 and March 31, 1999, there were approximately $1,490,000
and $500,000 of letters of credit outstanding, respectively.
 
(6) Bridge Financing
 
   In December 1997 the Company entered into an agreement to borrow $1.5
million of short-term bridge loans. The loans bear interest at 6% with an
original maturity date of March 31, 1998. The term of the debt was extended to
April 30, 1998, and the interest rate was increased to 15%. In connection with
this financing, the Company issued warrants (note 12) to acquire 45,000 shares
of the Company's common stock. The estimated fair value of the warrants issued
was approximately $23,000. This amount has been recorded as debt issuance costs
and was amortized over the term of the debt.
 
   In February, March and April 1998 the Company entered into various
agreements to borrow additional amounts of short-term bridge loans aggregating
$3.32 million. The terms of the debt were substantially identical with the
amount borrowed in December 1997. The Company issued warrants (note 12) to
acquire 48,182 shares of the Company's common stock at an exercise price equal
to the price per share at the time of closing of the Company's round of equity
financing in April 1998. The estimated fair value of the warrants issued was
approximately $46,000 and has been recorded as additional interest expense
through the date of the conversion of the bridge loans into Class B preferred
stock.
 
   The $4.82 million of short-term bridge loans were converted to Class B
preferred stock in April 1998 (note 11).

(8) Loan Payable/Receivable--Officers
   At December 31, 1997, approximately $4,000 was owed from an original amount
of approximately $111,000 to the former Chief Executive Officer of the Company.
The amount was repaid in full during 1998.
 
   At December 31, 1998, the Company has a loan receivable in the amount of
$60,000 due from an officer of the Company. The term of the loan receivable is
three years and is non-interest bearing. The Company has agreed to forgive the
loan in its entirety in the event the Company completes an IPO.
 
(9) Other Liabilities
 
   In October 1995 the Company entered into an emerging company funding
agreement with the Ben Franklin Technology Center of Southeastern Pennsylvania
(the Center). The Center had agreed to provide up to $100,000 to the Company
during the period November 1, 1995 to June 30, 1996. Any amounts funded by the
Center were to be used by the Company for the development of certain laptop
computer video capture products. The total amount funded by the Center was
repayable quarterly. The total amount outstanding as of December 31, 1997 was
$90,000. The amount was repaid in full during 1998.
 
   During 1997 the Company entered into a factoring arrangement for which
approximately $278,000 of accounts receivables had been pledged as collateral
with recourse to the Company. The effective interest rate on such secured
borrowings was approximately 30% at December 31, 1997. The Company discontinued
the factoring arrangement during 1998.
 
   In connection with the Company's acquisition of Viona during 1998 (note 4),
$1.35 million of the purchase price, recorded at a present value of $1.1
million, is payable in equal annual installments over the next three years. As
such, $0.4 million of the amount is included in other current liabilities with
the remaining amount included in other long-term liabilities.
 
(10) Subordinated Notes Payable
 
   Subordinated notes payable at December 31, 1997 and 1998 and March 31, 1999,
consist of $625,000 of various subordinated notes payable (the Notes) to NEPA
Venture II, L.P. (NEPA) due May 4, 2003 to November 29, 2003 with a 9% interest
rate.
 
   The Notes are part of two transactions entered into in May 1995 and March
1996 to provide financing to the Company. Interest on the Notes is payable
quarterly. In connection with the issuance of the Notes, the Company issued
warrants to acquire a total of 920,006 shares of the Company's Class A
mandatory redeemable

convertible preferred stock at exercise prices of $0.60-$0.75 per share (note
13). The estimated fair value of the warrants issued is $30,010 and is
amortized over the term of the related debt. In addition, NEPA obtained board
representation and certain other rights which include piggyback and demand
registration rights in certain circumstances following an initial public
offering.
 
(11) Equity Transactions and Capital Stock
 
  Capital Stock and Stock Splits
 
   The board of directors of the Company amended the Company's Articles of
Incorporation in April 1998 to increase the authorized common shares to
80,000,000, to increase the authorized Class A mandatory redeemable convertible
preferred shares to 6,523,684 and authorized 25,000,000 shares of Class B
mandatory redeemable convertible preferred shares (collectively, Preferred
Stock).
 
   In August and October 1996 the board of directors authorized a 1.929-to-1
and a 1.088-to-1 stock split, respectively, including common and preferred
shares. The splits coincided with the private placement transactions described
below.
 
   All share and per share information included in the accompanying
consolidated financial statements and notes has been adjusted to give effect to
the stock splits noted above.
 
  Common Stock
 
   In August and October 1996 the Company raised a total of $2 million through
a private placement of 347,936 shares of common stock. In connection with this
transaction, the Company paid $200,000 as a placement fee, and issued options
to purchase 66,151 shares of common stock at an average exercise price of $4.26
per share to a former director of the Company (note 17). The fair value of the
common stock on the date of grant was estimated to be $6.00. The options vested
immediately. The $200,000 of offering costs and the $150,450 value of the
options granted at below fair value have been recorded in additional paid-in
capital as costs of the equity transaction.
 
   During April through July 1996 the Company also sold 21,076 shares of common
stock for a total of $55,000, the estimated fair market value per share of the
Company's common stock on the date of the transaction, to two employees of the
Company. In January 1996, the Company sold 7,347 shares of common stock for a
total of $30,000, the estimated fair market value per share of the Company's
common stock on the date of the transaction. In addition, in January 1996 an
employee was given 31,373 shares of the Company's common stock as consideration
for previously accrued unpaid wages aggregating $18,750.
 
   In March and April 1997 the Company raised a total of $500,000 through a
private placement of 83,333 shares of the Company's common stock. In connection
with this transaction, the Company issued options to purchase 10,417 shares of
the Company's common stock at an exercise price of $4.50 per share to a
director of the Company that was actively involved in this fund raising
process. The options vested immediately. The $15,625 value of the options
granted at below fair value has been recorded in additional paid-in-capital as
costs of the equity transaction.
 
   In September and October 1997 the Company sold 30,000 shares of common stock
for $207,300 in a private transaction to unrelated third parties.

   In April 1998 the Company purchased 200,000 shares of common stock for $3.60
per share or $720,000 in the aggregate from the former CEO of the Company.
 
  Preferred Stock
 
   In April 1998 the Company sold 3,728,916 shares of Class B mandatory
redeemable convertible preferred stock (Class B) for an aggregate amount of
approximately $18.6 million including the conversion of $4.82 million of bridge
notes (note 6). In addition, the investors in the Class B received an aggregate
1,517,668 warrants (note 12) to acquire common stock at an exercise price of
$0.06. The estimated fair value of the warrants of $5.7 million has been
recorded as additional paid-in capital.
 
   The Preferred Stock has a non-cumulative dividend rate equal to 8% of the
original purchase price which shall become due and payable when and if declared
by the board of directors of the Company. To date, no dividends have been
declared by the board of directors. The holders of the Preferred Stock have
demand and piggyback registration rights as defined.
 
   Holders of Preferred Stock have the option to convert such shares into
shares of common stock on a 1:1 ratio. The conversion rate on a particular
class of Preferred Stock is subject to an adjustment in the event that any
additional common stock, or other shares convertible into common stock, are
issued for a per share price less than the particular class conversion price.
Mandatory conversion occurs upon the closing of an IPO of the Company's common
stock, as defined. The Class B is senior to the Company's Class A in
liquidation and the holders of Class A and B are entitled to receive an amount
equal to their respective redemption price prior to the distribution to the
common shareholders. At any time after May 4, 2003, each holder of shares of
Preferred Stock, may at their option, require the Company to redeem all or part
of their preferred shares.
 
   The Preferred Stock votes on an as if converted basis. The Class B
shareholders have the right to elect one member of the board of directors of
the Company.
 
   In April 1998, in connection with the Company's sale of Class B, the Company
paid $1.1 million in cash, issued 108,856 shares of the Company's Class B and
issued 44,304 warrants (note 13) to acquire common stock at an exercise price
of $0.06 to the Company's placement agent as consideration for services
provided in connection with the equity transaction. The shares and warrants had
an estimated fair value of $542,100. The above amounts as well as $0.3 million
of other transaction costs were recorded as costs of the equity transaction and
charged against additional paid-in capital.
 
   Preferred stock consists of the following at December 31, 1997 and 1998:

  Preferred Stock Subscription
 
   In March 1998, the Company entered into a subscription and technology
license agreement (the Agreement). The Agreement provides, among other things,
for the Company to license certain technology to an unrelated third party (the
licensee). In connection with this Agreement, the licensee is required to pay a
minimum of $750,000 at the end of each calendar quarter during the first year
and a minimum of $900,000 at the end of each calendar quarter during the second
year. Included in the first year quarterly payments is $125,000 per quarter
that will be applied towards the purchase of the Company's Class B preferred
stock at $4.98 per share. The quarterly payment for the fourth quarter of the
second year includes $500,000 that will be applied towards the purchase of the
Company's Class B preferred stock at $4.98 per share. The purchase of the
preferred stock under this Agreement is on the same terms as the licensee's
purchase of Class B preferred stock in April 1998. The $625,000 minimum
quarterly royalty payments in year one will be recognized as revenue during
each respective quarter. The $900,000 minimum quarterly payments for each of
the first three quarters and the $400,000 for the fourth quarter of the second
year will be recognized as revenue during each of those respective quarters.
 
   As of December 31, 1998, the Company has issued 75,301 shares of Class B
preferred stock under this Agreement.
 
   In April 1999 the Company issued 25,100 shares of Class B preferred stock
under this Agreement. In addition, the Company amended the above agreement and
issued 100,402 shares of Class B preferred stock and warrants for the purchase
of 51,079 shares of common stock in exchange for which it received a promissory
note with an aggregate value of $500,000 due in April 2000. The $500,000 note
reflects the payment due in the fourth quarter of the second year of the above
Agreement.
 
(12) Stock Options and Warrants
 
  (a) Stock Options
 
   The Company adopted the 1995 Stock Option Plan (the 1995 Plan) in May 1995.
The 1995 Plan provides for the grant of incentive stock options and non-
qualified stock options to employees, consultants, advisors to the Company, and
members of the Board of Directors to purchase shares of common stock. Prior to
the adoption of the 1995 Plan, 43,258 options were granted to employees. Under
the terms of the 1995 Plan, authorized options are granted at estimated fair
value. The options generally vest over a period ranging from 2 to 5 years and
expire 5 to 10 years from the grant date.
 
   In the months of November and December 1995, five Company managers deferred
payment of their salaries, aggregating approximately $42,000, for a period of
four years which is recorded as accrued compensation payable and is non-
interest bearing. In connection with their deferral of salaries, these managers
received a total of 50,510 non-qualified stock options to acquire shares of
common stock of the Company at an exercise price of $0.60, the estimated fair
value at the date of grant. These options were not issued in connection with
the 1995 Plan. The options become exercisable 20% per year commencing with the
grant date and on January 1 of each year thereafter.
 
   In September 1997 the Company granted 728,398 options, outside the 1995
Plan, to employees and certain vendors to purchase common stock at exercise
prices ranging from $1.50 to $6.00 per share. The options vest over a range of
periods from immediately to 4 years and expire in 5 years. Of these options,
299,315 were issued to employees at below fair value or to vendors which
resulted in a noncash charge to operations for the year ended December 31, 1997
of approximately $1,409,000.
 
   In 1998 the Board of Directors approved an amendment to the Company's 1995
Stock Option Plan in which the total number of options available for grant was
increased to 8,500,000.

      (Information with respect to March 31, 1998 and 1999 is unaudited)
 
 
   In September 1998 the Company granted 783,333 options, outside the 1995
Plan, to employees of Viona at an exercise price of $1.50 which was below the
estimated fair value of the Company's common stock on the date of grant. The
Company recorded deferred stock compensation of $799,000 in connection with
these options which will be amortized over the options' vesting period.
 
   On September 23, 1998 the Company, with the approval of the board of
directors, repriced all of the outstanding employee stock options that were in
excess of $2.52 to $2.52.

   The Company applies APB 25 and related interpretations in accounting for

fair value of stock options granted using a minimum value option-price model:

   Pro forma net loss reflects only options granted since 1996. Therefore, the
full impact of calculating compensation cost for stock options under SFAS No.
123 is not reflected in the pro forma loss amounts presented above because
compensation cost is reflected over an option's vesting period and compensation
cost for options granted prior to January 1, 1996, is not considered.
 
  (b) Warrants
 
   The warrants issued by the Company generally contain customary provisions
requiring proportionate adjustment of the exercise price in the event of a
stock split, stock dividend, or dilutive financing in the case of the warrants
for preferred stock.

</TABLE>
 
   Total rent expense for the years ended December 31, 1996, 1997 and 1998, was
approximately $107,000, $150,000 and $328,000, respectively, and approximately
$44,000 and $125,000 for the three months ended March 31, 1998 and 1999,
respectively.
 
  (b) Royalties
 
   Under various licensing agreements, the Company is required to pay
royalties, generally on a per unit basis, on the sales of certain products that
incorporate licensed technology. Royalty expense under such agreements was
approximately $188,000, $97,000 and $651,000 for the years ended December 31,
1996, 1997 and 1998, respectively, and approximately $65,000 and $192,000 for
the three months ended March 31, 1998 and 1999, respectively.
 
  (c) Contingencies
 
   The Company is party to certain legal actions arising in the normal course
of business. In addition, the Company is aware that several entities have
asserted that technology which forms an essential part of the industry standard
for DVD and which is incorporated into the Company's DVD solutions, infringes
patents held by such entities. If it is determined that the Company has
infringed these patents, the Company could be liable for damages and may be
required to pay license fees in connection with the use of the technology.
Management of the Company, however, does not believe the resolution of these
potential contingencies will have a material impact on the financial position
or results of operations of the Company.

  (d) Employment Agreements
 
   The Company has entered into employment agreements with certain officers and
employees of the Company. The agreements are generally for two to three year
periods, generally provide for annual bonuses and incentive stock options as
determined by the Board Directors, and covenants not-to-compete during the
employment term and for two years thereafter. The employment agreements also
generally provide for six months severance in the event the individual is
terminated without cause.
 
   The employment agreement with the Company's President and Chief Executive
Officer signed in August 1997 also provides that to the extent the Company is
sold for in excess of $80 million, he is entitled to a bonus of 2.5% of the
proceeds or $2 million.
 
(14) Business Risks and Credit Concentration
 
   The Company licenses and sells its products principally in the intensely
competitive personal computer and consumer electronics original equipment
manufacturers industry and for product sales prior to 1998 through a number of
wholesale distributors. This industry has been characterized by price erosion,
rapid technological change, short product life cycles, cyclical market patterns
and heightened foreign and domestic competition. Significant technological
changes in the industry would adversely affect operating results.
 
   The Company performs ongoing credit evaluations of its customers' financial
condition, and generally no collateral is required. The Company had three
customers representing, in the aggregate, 64%, 88% and 71% of accounts
receivable at December 31, 1997 and 1998 and March 31, 1999, respectively.
 
   The Company uses a contract manufacturer to make its hardware products. In
the event the Company is unable to continue its relationship with this
manufacturer, it believes it could establish a similar relationship with
another company in a reasonable period of time. Because of the competitive
nature of the technology industry, the Company believes it could ultimately
obtain terms as beneficial as those currently in effect.
 
(15) Income Taxes
 
   The Company elected "C" corporation status in September 1996. Prior to that
election, the Company was an "S" corporation.
 
   No federal or state income taxes are due as of December 31, 1997 and 1998.
 
   The components of the net deferred tax assets as of December 31, 1997 and
1998, consists of the following (in thousands):

   Deferred income taxes reflect the net tax effects of temporary differences
between carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. The ultimate realization of deferred tax assets is dependent upon the
generation of future taxable income during the periods in which temporary
differences representing net future deductible amounts become deductible. Due
to the uncertainty of the Company's ability to realize the benefit of the
deferred tax assets, the deferred tax assets are fully offset by a valuation
allowance at December 31, 1997 and 1998.
 
   As of December 31, 1998, the Company has approximately $14.1 million of net
operating loss carryforwards for federal tax purposes. These carryforwards will
begin expiring in 2011 if not utilized. In addition, the Company has net
operating loss carryforwards in certain states with various expiration periods
beginning in 2006.
 
   Under the Tax Reform Act of 1986, the utilization of a corporation's net
operating loss carryforward is limited following a greater than 50% change in
ownership. Due to the Company's prior and current equity transactions, the
Company's net operating loss carryforwards may be subject to an annual
limitation. Any unused annual limitation may be carried forward to future years
for the balance of the net operating loss carryforward period.
 
(16) Related-Party Transactions
 
   During 1996, the Company paid $10,000 to a director of the Company for
consulting services. In 1997, the Company paid this director a total of
$220,000 for additional consulting services. During 1998, this individual
resigned as a director of the Company and received $220,000 for consulting
services.
 
   In connection with certain equity transactions completed in 1996 (note 11),
this director received remuneration for his services in connection with these
equity transactions.
 
   The former Chief Executive Officer of the Company received $125,000 in
severance payments during 1998.
 
(17) Defined Contribution Plan
 
   In 1997, the Company established a defined contribution plan for qualified
employees as defined in the Plan. Participants may contribute up to 20% of pre-
tax compensation, as defined. Under the plan, the Company can make
discretionary contributions. To date, the Company has not made any
contributions to the Plan.

(18) Segment and Major Customer Information
 
   In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information, which established standards for reporting
information about operating segments in annual financial statements. The
Company operates in a single industry segment, which is the development and
licensing of its technology.
 
   The Company had the following customers that combined represented in excess
of 31% and 91% of revenues for the years ended December 31, 1997 and 1998,
respectively, and 95% and 83% for the three months ended March 31, 1998 and
1999, respectively (in thousands):

(19) Subsequent Events
 
  (a) Options Granted
 
   In February 1999, the Company granted 144,688 options, with an exercise
price of $2.52 per share. The Company has recorded $503,514 of deferred stock
compensation in connection with these options that will be amortized over the
option vesting period.
 
  (b) Stock Incentive Plan (unaudited)
 
   In April 1999, the Company, with the approval of the board of directors,
adopted the 1999 Stock Incentive Plan (1999 Plan) as a successor to the 1995
Plan. The 1999 Plan has reserved, subject to shareholder approval, 15% of the
outstanding common stock after the IPO, less 500,000 shares. The 1999 Plan has
three separate programs which include; the discretionary option grant program
under which employees may be granted options to purchase shares of common
stock; the stock issuance program under which eligible employees may be granted
shares of common stock; and the automatic grant program whereby eligible non-
employee board members are granted options to purchase shares of common stock.

  (c) Employee Stock Purchase Plan (unaudited)
 
   In April 1999, the Company, with the approval of the board of directors,
adopted an Employee Stock Purchase Plan (the Purchase Plan) and reserved
500,000 shares of common stock for issuance thereunder. The Purchase Plan
permits eligible employees to acquire shares of the Company's common stock
through periodic payroll deductions of up to 15% of total compensation. Each
offering period will have a maximum duration of 24 months. The price at which
the common stock may be purchased is 85% of the lesser of the fair market value
of the Company's common stock on the first day of the applicable offering
period or on the last day of the respective purchase period. The initial
offering period will commence on the effectiveness of the IPO and will end on
the last business day of July 2001.
 
  (d) Sale of Preferred Stock and License of Technology (unaudited)
 
   In April 1999 Divicore completed a financing in which it issued convertible
securities to Intel of $4.7 million and entered into a license agreement
covering certain Intel technology.
 
  (e) Initial Public Offering and Reincorporation (unaudited)
 
   In April 1999, the board of directors authorized the filing of a
registration statement with the SEC that would permit the Company to sell
shares of the Company's common stock in connection with a proposed IPO.
 
   In addition the board of directors authorized the Company to file Amended
and Restated Articles of Incorporation causing the Company to reincorporate as
a Delaware Corporation. The Amended and Restated Articles of Incorporation are
to be effective upon shareholder approval which is anticipated to occur
immediately prior to the effective date of the IPO. Upon the reincorporation,
the Company will be authorized to issue 30,000,000 shares of $.001 par value
common stock and 5,000,000 shares of $.001 par value undesignated preferred
stock. In connection therewith, the Company authorized a 1 for 6 reverse stock
split which will become effective at the date of the IPO. All shares and per
share amounts in the consolidated financial statements have been restated to
reflect the reverse stock split.

                         NOTES TO FINANCIAL STATEMENTS
 
                               December 31, 1997
 
(1) Description of Operations
 
   Viona Development Hard & Software Engineering GmbH (the Company) is a
limited liability company, organized under the laws of the Federal Republic of
Germany. The Company conducts research and development in the field of
convergence subsystem products and desktop digital video products for use
primarily in desktop personal computers or other electronic devices.
 
(2) Summary of Significant Accounting Policies
 
 (a) Foreign Currency Translation
 
   The functional currency of the Company is the German mark and the reporting
currency is the U.S. dollar. Functional currency assets and liabilities are
translated into U.S. dollars using the period-end exchange rate while revenues
and expenses are translated using average exchange rates during the year.
Adjustments resulting from the translation of function currency assets and
liabilities into U.S. dollars are recorded as a separate component of
stockholders' equity.
 
 (b) Use of Estimates
 
   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 (c) Fair Value of Financial Instruments
 
   The carrying amounts of the Company's financial instruments approximate fair
value due to the short maturity of those instruments.
 
 (d) Cash and Cash Equivalents
 
   The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.
 
 (e) Furniture and Equipment
 
   Furniture and equipment are stated at cost. Depreciation is computed using
the straight-line or declining balance method based on the estimated useful
lives of the various classes of furniture and equipment as follows:
 
<TABLE>
       <S>                                                               <C>
       Software......................................................... 3 years
       Computer equipment............................................... 3 years
       Research and development equipment............................... 3 years
       Furniture and fixtures........................................... 5 years
</TABLE>
 
 (f) Long-Lived Assets
 
   The Company reviews long-lived assets to be held and used by an entity for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
 
 
 (g) Revenue Recognition
 
   Revenue is recognized upon shipment of products to customers. Revenue
related to development contracts is recognized using the percentage-of-
completion method, based on performance milestones specified in the contract
where such milestones fairly reflect progress toward contract completion.
Revenue related to the Agreement with Divicore Inc. (formerly Quadrant
International Inc.) (see Note 9) is recognized using a cost-plus methodology,
whereby expenses incurred plus a fixed premium are invoiced monthly.
 
 (h) Research and Development Costs
 
   Research and development costs are expensed as incurred.
 
 (i) Income Taxes
 
   Income taxes are accounted for under the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

   German tax law applies a split-rate imputation with regard to the taxation
of the income of a company and its stockholders. In accordance with the tax
law in effect for fiscal 1997, retained income is initially subject to a
federal tax of 45% plus a solidarity surcharge of 7.5% on federal taxes
payable. Including the impact of the surcharge, the federal tax rate amounts
to 48.375%. Upon distribution of retained earnings to stockholders, the income
tax rate on the earnings is adjusted to 30%, plus a solidarity surcharge of
7.5% on the distribution tax, for a total of 32.25%, by means of a refund for
taxes previously paid. Upon distribution of retained earnings in the form of a
dividend, stockholders who are taxpayers in Germany are entitled to a tax
credit in the amount of federal income taxes previously paid by the company.
 
   For German companies, the deferred taxes for 1997 are calculated using an
effective income tax rate of 47.475% plus the after federal tax benefit rate
for trade tax of 8.525%.
 
   A reconciliation of income taxes determined using the German tax rate of
47.475% plus the after federal tax benefit rate for trade taxes of 8.525% for
a combined statutory rate of 56% in 1997 is as follow:

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
 
 
   Deferred income taxes reflect the net tax effects of temporary differences
between carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. The ultimate realization of deferred tax assets is dependent upon the
generation of future taxable income during the periods in which temporary
differences representing net future deductible amounts become deductible.
 
(7) Development Agreement
 
   On February 6, 1997, the Company entered into an exclusive development
agreement (the Agreement) with Divicore Inc. (Divicore), whereby the Company
agreed to exclusively develop personal computer-convergence products for
Divicore. Under the Agreement, the Company will receive fees from Divicore
monthly based on the greater of product engineering costs incurred plus a
premium or $80,000.
 
(8) Related-party Transactions
 
   In 1997, each of the Company's three owners granted a loan to the Company
for approximately $22,000 (DM 40,000). The loans bear interest at 7% per year
and are payable on demand. At December 31, 1997, each of these loans plus
accrued interest amounted to approximately $23,000. The statement of operations
for the year ended December 31, 1997 includes approximately $2,400 of interest
expense related to these loans. The Company believes the interest expense
incurred was equivalent to the amounts that would be paid under arm's-length
transactions.
 
(9) Subsequent Events
 
   In January 1998, the Company's stockholders agreed to sell the Company to
Divicore. In April 1998 the acquisition was completed and was accounted for as
a purchase business combination. The purchase consideration consisted of
1,204,820 shares of Divicore common stock and $6.1 million in cash.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION
 
   The following unaudited pro forma financial information is filed herewith:
unaudited combined pro forma statement of operations for the year ended
December 31, 1998.
 
   In April 1998 the Company completed the acquisition of Viona Development
Hard & Software Engineering GmbH (Viona) a company located in Germany
specializing in the development of digital video technology. The purchase price
included $6.1 million in cash, 1,204,820 shares of the Company's common stock
valued at $4.8 million and incurred transaction costs of $0.8 million. The
acquisition of Viona was recorded under the purchase method of accounting.
A portion of the purchase price was allocated to in-process research and
development technology, which resulted in a charge of $7.9 million to the
Company's operations in April 1998. The excess of the purchase price over the
fair value of the net identifiable assets and in-process research and
development technology acquired of $3.5 million has been recorded as goodwill
and is amortized on a straight-line basis over four years.
 
   The unaudited combined pro forma statement of operations reflects the
acquisition of Viona as if it occurred on January 1, 1998. Since the pro forma
financial statement which follows is based upon the operating results of Viona
during a period when it was not under the control or management of the Company
the information presented may not be indicative of the results which would have
actually been obtained had the acquisition been completed as of January 1, 1998
nor are they indicative of future financial or operating results. The unaudited
pro forma financial information does not give effect to any synergies that may
occur due to the integration the Company and Viona. The condensed combined pro
forma financial statement should be read in conjunction with the historical
audited financial statements of the Company and the notes thereto, as well as
the audited historical financial statements of Viona and the notes thereto
included elsewhere in this prospectus.

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
1. Basis of Presentation
 
   The accompanying unaudited pro forma combined statements of operations for
the year ended December 31, 1998 give effect to the acquisition of Viona as if
it had occurred on January 1, 1998.
 
   The effects of the acquisition have been presented using the purchase method
of accounting and accordingly, the purchase price was allocated to the assets
acquired and liabilities assumed based upon management's best estimate of their
fair value.
 
   The pro forma adjustments related to the purchase price allocation of the
acquisition represent management's best estimate of the effects of the
acquisition.
 
2. The pro forma statement of operations adjustments for the year ended
December 31, 1998 consist of:
 
   (a) Pro forma revenue and research and development expense has been adjusted
to reflect the elimination of the amounts paid by Divicore Inc. to Viona for
development services.
 
   (b) Pro forma general and administrative expense has been adjusted to
reflect the amortization of goodwill and other intangible assets associated
with the acquisition which has an estimated useful life of four years. ($3.5
million divided by 48 months = $0.07 million per month; $0.2 million
amortization per quarter).
 
   (c) Basic and diluted weighted average common shares outstanding and net
loss per share amounts have been adjusted to reflect the issuance of the
1,204,820 shares of the Company's common stock in connection with the
acquisition, as if the shares had been outstanding from January 1, 1998.
 
   (d) No income tax provision is required due to the Company's current tax
loss and the inability of the Company to currently use the benefits of the net
operating loss carryforward.

Item 14. Indemnification of Directors and Officers
 
   Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's board of directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). Article VII, Section 6 of Divicore's Bylaws
provides for mandatory indemnification of its directors and officers and
permissible indemnification of employees and other agents to the maximum
extent permitted by the Delaware General Corporation Law. Divicore's
Certificate of Incorporation provides that, subject to Delaware law, its
directors shall not be personally liable for monetary damages for breach of
the directors' fiduciary duty as directors to Divicore and its stockholders.
This provision in the Certificate of Incorporation does not eliminate the
directors' fiduciary duty, and in appropriate circumstances equitable remedies
such as 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 Divicore or its
stockholders for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are unlawful under Delaware law. The
provision also does not affect a director's responsibilities under any other
law, such as the federal securities laws or state or federal environmental
laws. Divicore has entered into indemnification agreements with its officers
and directors, a form of which was previously filed with the Securities and
Exchange Commission (the "Commission") as an Exhibit to the Registrant's
Registration Statement on Form S-1 (No. 333-              ) (the
"Indemnification Agreements"). The Indemnification Agreements provide
Divicore's officers and directors with further indemnification to the maximum
extent permitted by the Delaware General Corporation Law. Reference is also
made to Section     of the Underwriting Agreement contained in Exhibit 1.1
hereto, indemnifying officers and directors of Divicore against certain
liabilities, and Section 1.10 of the Registration Rights Agreement contained
in Exhibit 4.2 hereto, indemnifying certain of Divicore's stockholders,
including controlling stockholders, against certain liabilities.
 
Item 15. Recent Sales of Unregistered Securities
 
   During the past three years, the Registrant has issued unregistered
securities to a limited number of persons as described below:
 
    (a) During 1996, the Registrant issued and sold 96,529 shares of its
  common stock to employees and consultants for an aggregate purchase price
  of $103,750 pursuant to direct stock issuances.
 
                                     II-1
<PAGE>
 
    (b) In February 1996, the Registrant issued and sold 44,080 shares of its
  common stock to an employee for an aggregate purchase price of $30,000.
 
    (c) In March 1996, the Registrant issued and sold 7,347 shares of its
  common stock to an employee of the Registrant for an aggregate purchase
  price of $5,000.

Item 17. Undertakings
 
   Divicore 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 Divicore
pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation or the Bylaws of Divicore, Indemnification Agreements entered
into between Divicore and its officers and directors, the Underwriting
Agreement, or otherwise, Divicore has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act, and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by
Divicore of expenses incurred or paid by a director, officer, or controlling
person of Divicore 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, Divicore 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 of whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
   The undersigned registrant hereby undertakes:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  registration statement in reliance upon Rule 430A and contained in a form
  of Prospectus filed by Divicore pursuant to Rule 424(b)(1) or (4) or 497(h)
  under the Securities Act shall be deemed to be part of this Registration
  Statement as of the time it was declared effective;
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of Prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

additional representations, warranties, agreements and conditions to the Sales
Agreement and related Acquisition as set forth in, and required by, Section 9.2

          WHEREAS, the parties agree that this Appendix shall be attached to and
become a part of the Sales Agreement but it is not intended to and shall not

and complement the Sales Agreement.

          NOW, THEREFORE, in consideration of the premises and the agreements,

<PAGE>
 
          2.1  VIONA.  VIONA is a GmbH duly organized, validly existing and in
               -----
good standing under the laws of the Federal Republic of Germany, has the power
to own and lease its properties and to carry on its business as now being
conducted and is not required to qualify to do business in any other
jurisdiction. The Shareholders have caused to be delivered to QUADRANT, true and
complete copies of the charter documents and by-laws, or other constituent
documents of VIONA as in effect on the date hereof which instruments will not be
amended except as contemplated by the Sales Agreement or this Appendix, or
required by law.

          2.2  Subsidiaries, Partnerships, Joint Ventures.  VIONA does not have 
               ------------------------------------------

               -------------------------------------------------- 
Shareholder has the capacity, full legal right, power and authority to enter
into the Sales Agreement and this Appendix, and each of the Sales Agreement and
this Appendix is binding upon, and enforceable against, each of the Shareholders
in accordance with its terms, and no further action by the Shareholders, except
for the appearance before a German Notary on the date hereof to approve the
Sales Agreement, is required in order to consummate the within transactions. The
transfer to CINCO of the Shares contemplated by the Sales Agreement shall vest
in CINCO legal title to the Shares free and clear from all mortgages, liens,
claims and other encumbrances whatsoever. None of the execution and delivery of
the Sales Agreement and this Appendix by the Shareholders, consummation by the
Shareholders of the transactions contemplated hereby, or compliance by the
Shareholders with the terms and provisions of the Sales Agreement and this
Appendix, will conflict with, violate or result in a breach of any of the terms,
conditions or provisions of VIONA's Articles of Association or by-laws, or of
any statute, judgment, order, injunction, decree, regulation or ruling of any
court or governmental authority to which VIONA is subject. The consummation of
the transactions contemplated by the Sales Agreement and this Appendix will not
result in the breach of any agreement, contract or commitment of VIONA, or
constitute a material default thereunder, or give to others any rights of
termination, cancellation or acceleration thereunder, other than as set forth on
Annex A, nor will any indenture, instrument, agreement, contract or commitment
to which VIONA is a party be violated or breached so as to prevent such
consummation. No authorization, consent or approval of, or 

                                       3

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

and outstanding, fully paid and nonassessable. There are not any subscriptions,
options, calls or other agreements, commitments or demands of any character,

capital of VIONA or which restrict the transfer of the share capital currently
held by the Shareholders.

          2.5  Officers and Directors.  Annex B contains a list of the 
               ----------------------

properties or assets is subject. Except as disclosed in Annex C, VIONA is not
directly or indirectly liable upon or with respect to any other debt or
obligation relating to any lending or borrowing, except (i) as made in the

          2.9  Personal Property.  The personal property of VIONA is not subject
               ----------------- 
to any liens, encumbrances or imperfections of title (except for liens for

such properties to less than that reflected on such books and records.

          2.10 Leaseholds.  Annex D lists all leases or agreements under which
               ----------

          2.11 Insurance.  Annex E lists all policies of insurance covering
               ---------

(specifying the insurer, amount of coverage, type of insurance, policy number).
Any pending claims against or by VIONA which are material to VIONA are listed in
Annex E. True copies of all such policies have been delivered to QUADRANT. Such
policies are in amounts which are deemed to be adequate by the Shareholders,
provide coverage in accordance with industry norms, and will be maintained in
effect through the Initial Payment Closing Date. All of the policies listed on
Annex E are currently in effect and there has not been any failure to give any
notice or to present any claim under any insurance policy in due and timely
fashion which claim is material to VIONA.

          2.12 Intellectual Property.  Annex F lists all patent, trademark and
               --------------------- 
copyright registrations (registered or common law) and applications owned by
VIONA, and all of the products and technology produced by VIONA (the

                                       5
<PAGE>
 
          The Shareholders represent and warrant that: (i) all of the
intellectual property listed on Annex F is presently existing and has not been
abandoned; (ii) all of the intellectual property created by or for VIONA as set
forth on Annex F was developed and executed by VIONA employees as consultants
bound by written work made for hire agreements and assignment agreements
providing for VIONA's proprietary ownership of the respective intellectual
property set forth; (iii) no other firm, corporation, association or person has
(a) the right to use any such intellectual property in commerce on the products
on which they are now being used either in identical form thereof or in such
near resemblance thereof as to be likely, when applied to the goods of any such
person, to cause confusion or to cause mistake or to deceive, (b) claimed any
ownership or right to use such intellectual property; or (c) is infringing upon
any such intellectual property in any material way; and (iv) VIONA has not
received any form of notice that any such intellectual property is alleged to be
invalid or to infringe upon the rights of any other person. Notwithstanding the
provisions of Section 2.12(i) through (iv), the Shareholders acknowledge and
agree that VIONA and QUADRANT have been sharing the right to use, develop,
license and sell the intellectual property (ownership right) and shall continue
to share this right to the intellectual property as listed on Annex F.

          2.13  Labor Matters.  VIONA is not a member of an association of
                ------------- 
employers. The Shareholders are not aware of any notice having been received by

          2.16  Compliance with Laws.  References is made to Section 5.6 of the
                -------------------- 
Sales Agreement. In addition, VIONA has not been notified by any regulatory
authority that it is in violation of any statute, ordinance, regulation or order
which have application to its business, and the Shareholders are not aware of
any violation of any such law, ordinance, regulation or order which would result
in any loss or expense which would be material to VIONA. All material licenses
and permits necessary for the conduct of the business of VIONA consistent with
past practices are in force and effect. No unresolved violations are or have
been recorded in respect of any such license or permit of VIONA and no
proceeding is pending or threatened to revoke or limit any such license or
permit. There are no inspection reports or similar communications issued or
released by any governmental authority relating to the business or properties of
VIONA, and which asserts a deficiency not yet corrected or a matter still in
dispute, which deficiency or matter is material to VIONA.

          2.17  Tax Matters.  All taxes assessed by any governmental authority
                -----------
have been fairly reflected on the books of VIONA in accordance with generally
accepted accounting practices consistently applied, and the required tax returns
have been filed or legal extensions of 

                                       7

time for filing have been obtained. No taxing authorities have asserted any

between the date hereof and the Initial Payment Closing Date, VIONA will not,
without prior disclosure to and written consent of QUADRANT, do any of the
things listed in the preceding paragraph. Notwithstanding the provisions of this
Section 2.18, the Shareholders have informed QUADRANT that in 1997 partnership
interests in VIONA of one percent (1%) were bought back by VIONA for DM 500.00
and with respect to a capital appreciation the partnership interests in VIONA

52,500.00.  In addition, the power of attorney held by Mr. Thomas Pfrengle, who
resigned as fully authorized officer getting a severance payment of DM
95,000.00, was withdrawn.  Furthermore, notwithstanding the provisions of this
Section 2.18, the Shareholders have informed QUADRANT that they have passed a
Shareholders' Agreement concerning declaration of dividends for the year 1996
and concerning establishing of accruals.

          2.19  Bank Accounts.  Annex H contains a complete list of all bank
                ------------- 
accounts maintained by VIONA and all persons entitled to draw thereon. The
Shareholders have delivered to QUADRANT a complete list of safe deposit boxes
listing all persons with access thereto.

          2.20  Powers of Attorney.  The Shareholders have delivered to QUADRANT
                ------------------ 
a complete list of all persons holding powers of attorney from VIONA, together
with copies of such powers of attorney, including the Power of Attorney held by
Johannes Breh of the law firm of Honold & Partner to legally represent VIONA.

                ------------------------------------- 
VIONA reflect its significant items of income and expense, and its significant
assets, liabilities and accruals.

          2.22  Raw Materials.  VIONA is not experiencing any interruption in

the supply of raw materials which has had or threatens to have any material
adverse effect on the business of VIONA.

          2.23  Diligence Investigation.  The Shareholders have made a diligent
                -----------------------

QUADRANT and in other

<PAGE>
 
materials delivered to QUADRANT to communicate to QUADRANT all information
(other than information generally known in the industry) which the Shareholders
believe would materially adversely affect the business of VIONA. No annex,
exhibit or other information furnished by the Shareholders to QUADRANT in
connection with the Sales Agreement or this Appendix contains any untrue
statement of a material fact or omits a material fact which thereby in light of
the circumstances in which it was made, or omitted, could mislead QUADRANT or
its representatives.

          Section 3.  Representations of QUADRANT and CINCO.
                      ------------------------------------- 

           QUADRANT and CINCO represent and warrant to, and agree with, the
Shareholders as follows:

          3.1  Organization and Qualification.  QUADRANT is a corporation duly
               ------------------------------ 
organized, validly existing and in good standing under the laws of the
Commonwealth of Pennsylvania and CINCO is a GmbH duly organized, validly
existing and in good standing under the laws of the Federal Republic of Germany,
and each has all requisite corporate power and authority to enter into and carry
out its obligations under the Sales Agreement and this Appendix and the Sales
Agreement and this Appendix constitute binding obligations of each of QUADRANT
and CINCO enforceable against them according to its terms, except as may be
limited by laws of general application. The execution and delivery of the Sales
Agreement and this Appendix and the consummation of the transactions
contemplated thereby and hereby have been duly authorized by the Board of
Directors of QUADRANT and all necessary corporate action on behalf of CINCO has
been taken and no other corporate proceedings on the part of either QUADRANT or
CINCO (including shareholder action) are necessary to authorize the Sales
Agreement and this Appendix and the transactions contemplated thereby and
hereby. None of the execution and delivery of the Sales Agreement and this
Appendix by QUADRANT and CINCO, consummation by QUADRANT and CINCO of the
transactions contemplated thereby and hereby or compliance by QUADRANT and CINCO
with the terms and provisions thereof and hereof, will conflict with or result
in the breach of any of the terms, conditions or provisions of the Certificate
of Incorporation or By-Laws of QUADRANT, or the Article of Association and other
corporate documents of CINCO, or of any statute, judgment, order, injunction,
decree, regulation or ruling of any court or governmental authority to which
QUADRANT or CINCO is subject or of any agreement, contract or commitment which
is 

                                       10
<PAGE>
 
material to the business or properties of QUADRANT or CINCO, or constitute a
material default thereunder, or give to others any material rights of
termination, cancellation or acceleration thereunder. No authorization, consent
or approval of, or filing with, any public body or authority is necessary for
the consummation by CINCO and QUADRANT of the transactions contemplated by the
Sales Agreement and this Appendix, except as may be set forth on Annex A.

          3.2  QUADRANT Stock to be Delivered. The shares of QUADRANT Common 
               ------------------------------ 
Stock which are to be delivered by CINCO pursuant to Schedule A of the Sales
Agreement will be, when so delivered, validly authorized, duly issued, fully
paid and nonassessable.

          3.3  Financial Statements.  QUADRANT has furnished to the Shareholders
               --------------------
audited financial statements for the years ended December 31, 1995 and 1996 and
unaudited monthly financial statements for the period January 1, 1997 through
November 30, 1997. Such financial statements fairly present the financial
condition at the dates of the Balance Sheets and the results of operations of
QUADRANT for the periods indicated. Since November 30, 1997 there has been no
material adverse change in the business or financial condition of QUADRANT.

          Section 4.  Additional Agreements of the Parties.
                      ------------------------------------ 

          4.1  Consents.  The Shareholders agree to use their best efforts to

               --------------------------------------------
Initial Payment Closing Date, the Shareholders, working with QUADRANT and CINCO,

          4.3  Consent to Jurisdiction in Connection with Appendix. (a) To the
               ---------------------------------------------------
extent that German law does not imperatively govern the Sales Agreement and this
Appendix, each of the Shareholders hereby irrevocably submits to the
jurisdiction of any state or federal court sitting in the Borough of Manhattan,
City and State of New York for purposes of any suit, action or proceeding
arising out of or related to the provisions of this Appendix and the Annexes and
Exhibits hereto. Nothing contained in this Section 4.3 shall conflict with or
supersede the provisions of Section 10.4 of the Sales Agreement which shall be
applicable to the terms of the Sales Agreement as well as those terms of the
Appendix repeating and/or explaining and/or detailing and/or executing terms and
conditions of the Sales Agreement. Each of the Shareholders hereby irrevocably
waives, to the fullest extent permitted by law, any objection which he may have
to the laying of the venue of any such suit, action or proceeding brought in
such a court and any claim that any such suit, action or proceeding brought in
such a court has been brought in an inconvenient forum as it relates to issues
arising under this Appendix. Each of the Shareholders also agrees that final
judgment in any such suit, action or proceeding brought in such court shall be
conclusive and binding upon him and may be enforced in any court, to the
jurisdiction of which he is subject, by a suit upon such judgment; provided,
however, that service of process is effected upon him in the manner specified
herein.

          (b)  Each of the Shareholders agree that service of all writs, claims,
process and summonses in any suit, action or proceeding described above against
him in the State of New York may be made upon Corporation Service Company, 80
State Street, Albany, NY 12207-2543 (the "Process Agent"), and each of the
Shareholders irrevocably appoints the Process Agent as his agent and true and
lawful attorney-in-fact in his name, place and stead to accept such service of
any and all such writs, claims, process and summonses, and agrees that the
failure of the Process Agent to give any notice to him of any such service of
process shall not impair or affect the validity of such service or of any
judgment based thereon.  Each of the Shareholders agrees to maintain for a
period of three (3) years after the Initial Payment Date an agent with offices
in New York to act as his Process Agent. According to Section 10.1 of the Sales
Agreement, the costs of the Process Agent shall be borne by QUADRANT.  Nothing
herein shall in any way be deemed to limit the ability to serve any such writs,
process or summonses in any other manner permitted by applicable law.

times prior to the Initial Payment Closing Date, the Shareholders shall afford
to representatives of QUADRANT and CINCO, reasonable access to the offices,
plants, properties, books, contracts and records of VIONA during normal business
hours, in order that QUADRANT may have full opportunity to make such
investigations as it desires of the affairs and assets of VIONA. In the event of
termination of the Sales Agreement and this Appendix QUADRANT shall, at the
request of the Shareholders, deliver to VIONA all documents, work papers and
other material obtained by QUADRANT and CINCO, or on their behalf, from VIONA
and all copies thereof, whether so obtained before or after the execution of the
Sales Agreement and this Appendix, and shall not themselves use directly or
indirectly or through any subsidiary, any confidential information so obtained,
or otherwise obtained from VIONA hereunder or in connection herewith (unless

hereof from a third party having a bona fide right to provide the same to
QUADRANT or CINCO), and shall endeavor to have all such information kept

                                 DIVICORE INC.


          The undersigned, Francis E.J. Wilde III and Jason C. Liu, hereby
certify that:

          ONE:  They are the duly elected and acting President and Secretary,
          ---                                                                
respectively, of said corporation.

          TWO:  The Certificate of Incorporation of said corporation was
          ---                                                           
originally filed in the Office of the Secretary of State of the State of
Delaware on April __, 1999.

          THREE:  The Certificate of Incorporation of said corporation shall be
          -----                                                                
amended and restated to read in full as follows:

                                   ARTICLE I

          The name of this corporation is Divicore Inc. (the "Corporation").

                                  ARTICLE II

          The address of the Corporation's registered office in the State of
Delaware is 1209 Orange Street, in the City of Wilmington, County of New Castle.
The name of the Corporation's registered agent at such address is the
Corporation Trust Corporation.

                                  ARTICLE III

          The nature of the business or purposes to be conducted or promoted is
to engage in any lawful act or activity for which corporations may be organized
under the General Corporation Law of the State of Delaware (the "GCL").

                                  ARTICLE IV

          The Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares that the Corporation is authorized to issue is fifty five million
(55,000,000). Fifty million (50,000,000) shares shall be Common Stock, par value
$0.001 per share, and five million (5,000,000) shares shall be Preferred Stock,
par value $0.001 per share.
<PAGE>
 
          The Preferred Stock may be issued from time to time in one or more
series, without further stockholder approval.  The Board of Directors of the
Corporation is hereby authorized to fix or alter the rights, preferences,
privileges and restrictions granted to or imposed upon each series of Preferred
Stock, and the number of shares constituting any such series and the designation
thereof, or of any of them.  The rights, privileges, preferences and
restrictions of any such additional series may be subordinated to, pari passu
                                                                   ----------
with (including, without limitation, inclusion in provisions with respect to
liquidation and acquisition preferences, redemption and/or approval of matters
by vote), or senior to any of those of any present or future class or series of
Preferred Stock or Common Stock.  The Board of Directors is also authorized to
increase or decrease the number of shares of any series prior or subsequent to
the issue of that series, but not below the number of shares of such series then
outstanding.  In case the number of shares of any series shall be so decreased,
the shares constituting such decrease shall resume the status which they had
prior to the adoption of the resolution originally fixing the number of shares
of such series.

          Upon the filing of this Amended and Restated Certificate of
Incorporation, each  outstanding share of Common Stock shall be converted into
_____ (___) shares of Common Stock or Preferred Stock, as the case may be (the
"Stock Split").  No fractional shares of Common Stock or Preferred Stock, as the
case may be, shall be issued upon the Stock Split.  In lieu of any fractional
shares to which the holder would otherwise be entitled (after aggregating all
such shares of Common Stock, to which such holder is entitled), the Corporation
shall pay such holder such amount in cash as such fractional share represents
based on the fair market value of the Common Stock as of the date hereof.

                                   ARTICLE V

          In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to make, repeal, alter,
amend and rescind any or all of the Bylaws of the Corporation.  In addition, the
Bylaws may be amended by the affirmative vote of holders of at least sixty-six
and two-thirds percent (66 2/3%) of the outstanding shares of voting stock of
the Corporation entitled to vote at an election of directors.

                                  ARTICLE VI

          The number of directors of the Corporation shall be determined by
resolution of the Board of Directors.

          Elections of directors need not be by written ballot unless the Bylaws
of the Corporation shall so provide.  Advance notice of stockholder nominations
for the election of directors and of any other business to be brought before any
meeting of the stockholders shall be given in the manner provided in the Bylaws
of this Corporation.

          At each annual meeting of stockholders, directors of the Corporation
shall be elected to hold office until the expiration of the term for which they
are elected, or until their successors have been duly elected and qualified;
except that if any such election shall not be so held, such election shall take
place at a stockholders' meeting called and held in accordance with the GCL.
<PAGE>
 
          The directors of the Corporation shall be divided into three (3)
classes as nearly equal in size as is practicable, hereby designated Class I,
Class II and Class III.  For the purposes hereof, the initial Class I, Class II
and Class III directors shall be those directors so designated by a resolution
of the Board of Directors.  At the first annual meeting of stockholders
following the closing of the initial public offering of the Corporation's Common
Stock, the term of office of the Class I directors shall expire and Class I
directors shall be elected for a full term of three (3) years.  At the second
annual meeting of stockholders following the closing of the initial public
offering of the Corporation's Common Stock, the term of office of the Class II
directors shall expire and Class II directors shall be elected for a full term
of three (3) years.  At the third annual meeting of stockholders following the
initial public offering of the Corporation's Common Stock, the term of office of
the Class III directors shall expire and Class III directors shall be elected
for a full term of three (3) years.  At each succeeding annual meeting of
stockholders, directors shall be elected for a full term of three (3) years to
succeed the directors of the class whose terms expire at such annual meeting.
If the number of directors is hereafter changed, each director then serving as
such shall nevertheless continue as a director of the Class of which he is a
member until the expiration of his current term and any newly created
directorships or decrease in directorships shall be so apportioned among the
classes as to make all classes as nearly equal in number as is practicable.

          Vacancies occurring on the Board of Directors for any reason may be
filled by vote of a majority of the remaining members of the Board of Directors,
even if less than a quorum, at any meeting of the Board of Directors.  A person
so elected by the Board of Directors to fill a vacancy shall hold office for the
remainder of the full term of the director for which the vacancy was created or
occurred and until such director's successor shall have been duly elected and
qualified.  A director may be removed from office by the affirmative vote of the
holders of 66 2/3% of the outstanding shares of voting stock of the Corporation
entitled to vote at an election of directors, provided that such removal is for
cause.

                                  ARTICLE VII

          Stockholders of the Corporation shall take action by meetings held
pursuant to this Amended and Restated Certificate of Incorporation and the
Bylaws and shall have no right to take any action by written consent without a
meeting.  Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide.  Special meetings of the stockholders, for
any purpose or purposes, may only be called by the Board of Directors of the
Corporation.  The books of the Corporation may be kept (subject to any provision
contained in the statutes) outside the State of Delaware at such place or places
as may be designated from time to time by the Board of Directors or in the
Bylaws of the Corporation.

                                 ARTICLE VIII

          To the fullest extent permitted by applicable law, this Corporation is
authorized to provide indemnification of (and advancement of expenses to)
directors, officers, employees and agents (and any other persons to which
Delaware law permits this Corporation to provide indemnification) through Bylaw
provisions, agreements with such agents or other persons, vote of stockholders
or disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 145 of the GCL, subject only to
limits created by 
<PAGE>
 
applicable Delaware law (statutory or non-statutory), with respect to action for
breach of duty to the Corporation, its stockholders, and others.

          No director of the Corporation shall be personally liable to the
Corporation or any stockholder for monetary damages for breach of fiduciary duty
as a director, except for any matter in respect of which such director shall be
liable under Section 174 of the GCL or any amendment thereto or shall be liable
by reason that, in addition to any and all other requirements for such
liability, such director (1) shall have breached the director's duty or loyalty
to the Corporation or its stockholders, (2) shall have acted in manner involving
intentional misconduct or a knowing violation of law or, in failing to act,
shall have acted in a manner involving intentional misconduct or a knowing
violation of law, or (3) shall have derived an improper personal benefit.  If
the GCL is hereafter amended to authorize the further elimination or limitation
of the liability of a director, the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the GCL, as so
amended.

          Each person who was or is made a party or is threatened to be made a
party to or is in any way involved in any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (hereinafter a "proceeding"), including any appeal therefrom, by
reason of the fact that he or she, or a person of whom he or she is the legal
representative, is or was a director or officer of the Corporation or a direct
or indirect subsidiary of the Corporation, or is or was serving at the request
of the Corporation as a director or officer of another entity or enterprise, or
was a director or officer of a foreign or domestic corporation which was
predecessor corporation of the Corporation or of another entity or enterprise at
the request of such predecessor corporation, shall be indemnified and held
harmless by the Corporation, and the Corporation shall advance all expenses
incurred by any such person in defense of any such proceeding prior to its final
determination, to the fullest extent authorized by the GCL.  In any proceeding
against the Corporation to enforce these rights, such person shall be presumed
to be entitled to indemnification and the Corporation shall have the burden of
proving that such person has not met the standards of conduct for permissible
indemnification set forth in the GCL.  The rights to indemnification and
advancement of expenses conferred by this Article VIII shall be presumed to have
been relied upon by the directors and officers of the Corporation in serving or
continuing to serve the Corporation and shall be enforceable as contract rights.
Said rights shall not be exclusive of any other rights to which those seeking
indemnification may otherwise be entitled.  The Corporation may, upon written
demand presented by a director or officer of the Corporation or of a direct or
indirect subsidiary of the Corporation, or by a person serving at the request of
the Corporation as a director or officer of another entity or enterprise, enter
into contracts to provide such persons with specified rights to indemnification,
which contracts may confer rights and protections to the maximum extent
permitted by the GCL, as amended and in effect from time to time.

          If a claim under this Article VIII is not paid in full by the
Corporation within sixty (60) days after a written claim has been received by
the Corporation, the claimant may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part, the claimant shall be entitled to be paid also the expenses of
prosecuting such claim.  It shall be a defense to any such action (other than an
action brought to enforce the right to be advanced expenses incurred in
defending any proceeding prior to its final disposition where the required
undertaking, if any, has been tendered to the Corporation ) that 
<PAGE>
 
the claimant has not met the standards of conduct which make it permissible
under the GCL for the Corporation to indemnify the claimant for the amount
claimed, but the claimant shall be presumed to be entitled to indemnification
and the Corporation shall have the burden of proving that the claimant has not
met the standards of conduct for permissible indemnification set forth in the
GCL.

          If the GCL is hereafter amended to permit the Corporation to provide
broader indemnification rights than said law permitted the Corporation to
provide prior to such amendment, the indemnification rights conferred by this
Article VIII shall be broadened to the fullest extent permitted by the GCL, as
so amended.

                                  ARTICLE IX

          The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Amended and Restated Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all
rights conferred upon stockholders herein are granted subject to this
reservation.  Notwithstanding the foregoing, the provisions set forth in
Articles V, VI, VII, VIII and IX of this Amended and Restated Certificate of
Incorporation may not be repealed or amended in any respect without the
affirmative vote of holders at least 66-2/3% of the outstanding voting stock of
the Corporation entitled to vote at election of directors.

          FOUR:   The foregoing amendment and restatement has been duly adopted
          ----                                                                  
by the Corporation's Board of Directors in accordance with the applicable
provisions of Sections 242 and 245 of the General Corporation Law of the State
of Delaware.

          FIFTH:  The foregoing amendment and restatement was approved by the
          -----                                                              
holders of the requisite number of shares of the Corporation in accordance with
Section 228 of the General Corporation Law of the State of Delaware.

          IN WITNESS WHEREOF, the undersigned have executed this certificate on
_______ __, 1999.

of the directors then in office, even if less than a quorum, or by a sole
remaining director, and the directors so chosen shall hold office until the next
election of the class for which such directors were chosen and until their
successors are duly elected and qualified or until earlier resignation or

Directors shall be held at such time and place as shall be fixed by the vote of
the stockholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to constitute the
meeting, provided a quorum shall be present. In the event of the failure of the
stockholders to fix the time or place of such first meeting of the newly elected
Board of Directors, or in the event such meeting is not held at the time and

committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of conference telephone or
similar communications equipment by means of which all persons participating in

to fix the compensation of directors.  The directors may be paid their expenses,
if any, of attendance at each meeting of the Board of Directors and may be paid
a fixed sum for attendance at each meeting of the Board of Directors or a stated

to have a certificate, signed by, or in the name of the corporation by, the
Chairman of the Board of Directors, or the president or a vice-president and the
treasurer or an assistant treasurer, or the secretary or an assistant secretary
of the corporation, certifying the number of shares owned by him/her in the
corporation.

upon the face or back of the certificates issued to represent any such partly
paid shares, the total amount of the consideration to be paid therefor, and the

be issued by the corporation with the same effect as if he/she were such

issue of a new certificate or certificates, the Board of Directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his/her
legal representative, to advertise the same in such manner as it shall require
and/or to give the corporation a bond in such sum as it may direct as indemnity
against any claim that may be made against the corporation with respect to the

                                  FISCAL YEAR

          Section 4.  The fiscal year of the corporation shall be fixed by
          ----------

          ----------                                                          
inscribed thereon the name of the corporation, the year of its organization and

                                INDEMNIFICATION

          Section 6.  The corporation shall, to the fullest extent authorized
          ----------                                                         
under the laws of the State of Delaware, as those laws may be amended and
supplemented from time to time, indemnify any director made, or threatened to be
made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director of the
corporation or a predecessor corporation or, at the corporation's request, a
director or officer of another corporation, provided, however, that the
corporation shall indemnify any such agent in connection with a proceeding
initiated by such agent only if such proceeding was authorized by the Board of
Directors of the corporation.  The indemnification provided for in this Section
6 shall: (i) not be deemed exclusive of any other rights to which those
indemnified may be entitled under any bylaw, agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in their official
capacities and as to action in another capacity while holding such office, (ii)
continue as to a person who has ceased to be a director, and (iii) inure to the
benefit of the heirs, executors and administrators of such a person.  The
corporation's obligation to provide indemnification under this Section 6 shall
be offset to the extent of any other source of indemnification or any otherwise
applicable insurance coverage under a policy maintained by the corporation or
any other person.

          Expenses incurred by a director of the corporation in defending a
civil or criminal action, suit or proceeding by reason of the fact that he is or
was a director of the corporation (or 

                                       19
<PAGE>
 
was serving at the corporation's request as a director or officer of another
corporation) shall 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 such director to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation as
authorized by relevant sections of the General Corporation Law of Delaware.
Notwithstanding the foregoing, the corporation shall not be required to advance
such expenses to an agent who is a party to an action, suit or proceeding
brought by the corporation and approved by a majority of the Board of Directors
of the corporation which alleges willful misappropriation of corporate assets by
such agent, disclosure of confidential information in violation of such agent's
fiduciary or contractual obligations to the corporation or any other willful and
deliberate breach in bad faith of such agent's duty to the corporation or its
stockholders.

          The foregoing provisions of this Section 6 shall be deemed to be a
contract between the corporation and each director who serves in such capacity
at any time while this bylaw is in effect, and any repeal or modification
thereof shall not affect any rights or obligations then existing with respect to
any state of facts then or theretofore existing or any action, suit or
proceeding theretofore or thereafter brought based in whole or in part upon any
such state of facts.

          The Board of Directors in its discretion shall have power on behalf of
the corporation to indemnify any person, other than a director, made a party to
any action, suit or proceeding by reason of the fact that he, his testator or
intestate, is or was an officer or employee of the corporation.

          To assure indemnification under this Section 6 of all directors,
officers and employees who are determined by the corporation or otherwise to be
or to have been 

                                       20
<PAGE>
 
"fiduciaries" of any employee benefit plan of the corporation which may exist
from time to time, Section 145 of the General Corporation Law of Delaware shall,
for the purposes of this Section 6, be interpreted as follows: an "other
enterprise" shall be deemed to include such an employee benefit plan, including
without limitation, any plan of the corporation which is governed by the Act of
Congress entitled "Employee Retirement Income Security Act of 1974," as amended
from time to time; the corporation shall be deemed to have requested a person to
serve an employee benefit plan where the performance by such person of his
duties to the corporation also imposes duties on, or otherwise involves services
by, such person to the plan or participants or beneficiaries of the plan; excise
taxes assessed on a person with respect to an employee benefit plan pursuant to
such Act of Congress shall be deemed "fines."

                                  ARTICLE VIII


                                   AMENDMENTS

          Section 1.  These bylaws may be altered, amended or repealed or new
          ----------                                                         
bylaws may be adopted by the affirmative vote of holders of at least 66-2/3%
vote of the outstanding voting stock of the corporation.  These bylaws may also
be altered, amended or repealed or new bylaws may be adopted by the Board of
Directors, when such power is conferred upon the Board of Directors by the
certificate of incorporation.  The foregoing may occur at any regular meeting of
the stockholders or of the Board of Directors or at any special meeting of the
stockholders or of the Board of Directors if notice of such alteration,
amendment, repeal or adoption of new bylaws be contained in the notice of such
special meeting.  If the power to adopt, amend or repeal bylaws is conferred
upon the Board of Directors by the certificate of incorporation it shall not
divest or limit the power of the stockholders to adopt, amend or repeal bylaws.

             1.2.   Request for Registration.
                    ------------------------ 

                    (a)  If the Company shall receive at any time after the
effective date of the first registration statement for a public offering of
securities of the Company and after the Company qualifies for registering
securities on a Form S-3 (other than a registration statement relating either to
the sale of securities to employees of the Company pursuant to a stock option,
stock purchase or similar plan or a SEC Rule 145 transaction), a written request
from the Holders of at least (i) sixty-seven percent (67%) of the Registrable
Securities then outstanding or (ii) a majority in interest of the Class B
Preferred Stock, that the Company file a registration statement under the Act
covering the registration of at least twenty percent (20%) of the Registrable
Securities then held by such Holders then the Company shall:

                         (i)  within ten (10) days of the receipt thereof, give
written notice of such request to all Holders; and

                         (ii) file such registration within 30 days of the
mailing of such notice by the Company in accordance hereof and cause such
registration to be effective as soon

                                       3
<PAGE>
 
as practicable under the Act of all Registrable Securities which the Holders
request to be registered, subject to the limitations of subsection 1.2(b).

                    (b)  If the Holders initiating the registration request
hereunder ("Initiating Holders") intend to distribute the Registrable Securities
covered by their request by means of an underwriting, they shall so advise the
Company as a part of their request made pursuant to subsection 1.2(a) and the
Company shall include such information in the written notice referred to in
subsection 1.2(a). The underwriter will be selected by the Company and shall be
reasonably acceptable to a majority in interest of the Initiating Holders. In
such event, the right of any Holder to include such Holder's Registrable
Securities in such registration shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating Holders and such Holder) to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall (together with the Company as provided in subsection
1.4(e)) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting. Notwithstanding any
other provision of this Section 1.2, if the underwriter advises the Initiating
Holders in writing that marketing factors require a limitation of the number of
shares to be underwritten, then the Initiating Holders shall so advise all
Holders of Registrable Securities which would otherwise be underwritten pursuant
hereto, and the number of shares of Registrable Securities that may be included
in the underwriting shall be allocated among all Holders thereof, including the
Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each Holder; provided, however,
that the number of shares of Registrable Securities issued or issuable upon
conversion of the Class A Preferred Stock and the Class B Preferred Stock of the
Company to be included in such underwriting shall not be reduced unless all
other securities are first entirely excluded from the underwriting.

                    (c)  The Company may include in a registration requested
under Section 1.2(a) any additional authorized shares of the Common Stock of the
Company, whether or not issued, for sale by the Company; provided, however, that
such shares shall not be included to the extent that the Holders of a majority
of the shares of Registrable Securities held by the Investors included therein
determine in good faith that the inclusion of such shares will interfere with
the successful marketing of the shares of Registrable Securities to be included
therein; and provided, further, that if the number of shares to be so included
equals or exceeds the number of shares of Registrable Securities included
therein by the holders of Registrable Securities, such registration shall be
deemed to be a registration pursuant to Section 1.3 hereof.

                    (d)  Notwithstanding the foregoing, if the Company shall
furnish to Holders requesting a registration statement pursuant to this Section
1.2 or Section 1.12, a certificate of the Company signed by the Chief Executive
Officer of the Company stating that in the good faith judgment of the Board of
Directors of the Company, the filing of such registration statement would (A)
interfere with or affect the negotiation or completion of any material
transaction that is being contemplated by the Company or (B) involve initial or
continuing disclosure obligations materially adverse to the best interests of
the Company's shareholders, and it is therefore essential to defer the filing of
such registration statement, the Company shall have the right to defer taking
action with respect to such filing for a period of not more than sixty (60) days
after receipt of the request of the Initiating Holders; provided, however, that
the Company

                                       4
<PAGE>
 
may not utilize this right more than once in any twelve-month period, and the
time periods referred to in this Section 1.2 or Section 1.12 shall be extended
for an additional number of business days during which the rights to sell shares
were suspended.

                    (e)  In addition, the Company shall not be obligated to
effect, or to take any action to effect, any registration pursuant to this
Section 1.2:

                         (i)  After the Company has effected two registrations
pursuant to this Section 1.2 and such registrations have been declared or
ordered effective; or

                         (ii) During the period ending on a date six (6) months
after the effective date of a registration subject to Sections 1.2 or 1.3
hereof.

             1.3.   Company Registration. If (but without any obligation to do
                    --------------------
so) the Company proposes to register (including for this purpose a registration
effected by the Company for shareholders other than the Holders) any of its
stock or other securities under the Act in connection with the public offering
of such securities solely for cash (other than a registration relating solely to
the sale of securities to participants in a Company stock plan, a registration
on any form which does not include substantially the same information as would
be required to be included in a registration statement covering the sale of the
Registrable Securities or a registration in which the only Common Stock being
registered is Common Stock issuable upon conversion of debt securities which are
also being registered or covering only securities proposed to be issued in
exchange for securities or assets of another corporation or an SEC Rule 145
transaction), the Company shall, at such time, promptly give each Holder written
notice of such registration. Upon the written request of each Holder given
within twenty (20) days after mailing of such notice by the Company in
accordance with Section 2.6, the Company shall, subject to the provisions of
Section 1.8, use its best efforts to cause to be registered under the Act all of
the Registrable Securities that each such Holder has requested to be registered.
In no event, however, shall any holder of registration rights be granted
registration rights under this Section 1.3 that are superior to the registration
rights of the Holders without the written consent of the holders of at least 50%
of the Registrable Securities.

             1.4.   Obligations of the Company. Whenever required under this
                    --------------------------
Section 1 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                    (a)  Prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use its best efforts to cause
such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder with
respect to a registration under Sections 1.2 and 1.12, keep such registration
statement effective for the period necessary (but, other than as provided below,
in no event more than nine (9) months) to complete the proposed public offering;
provided, however, that (i) such nine (9)-month period shall be extended for a
period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of
Common Stock (or other securities) of the Company; and (ii) in the case of any
registration of Registrable Securities on Form S-3 which are intended to be
offered on a continuous or delayed basis, such 120-day period shall be extended,
if necessary, but for not

                                       5
<PAGE>
 
more than a period of two (2) years, to keep the registration statement
effective until all such Registrable Securities are sold, provided that Rule
415, or any successor rule under the Act, permits an offering on a continuous or
delayed basis, and provided further that applicable rules under the Act
governing the obligation to file a post-effective amendment permit, in lieu of
filing a post-effective amendment which (i) includes any prospectus required by
Section 10(a)(3) of the Act or (ii) reflects facts or events representing a
material or fundamental change in the information set forth in the registration
statement, the incorporation by reference of information required to be included
in (i) and (ii) above to be contained in periodic reports filed pursuant to
Section 13 or 15(d) of the 1934 Act in the registration statement.

                    (b)  Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Act with respect to the disposition of all securities covered
by such registration statement.

                    (c)  Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

                    (d)  Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; provided that the Company shall not be required in connection therewith
or as a condition thereto to (i) qualify to do business as a foreign corporation
or (ii) to file a general consent to service of process in any such states or
jurisdictions, unless the Company is already subject to service in such
jurisdiction, or (iii) register in any state requiring, as a condition to
registration, escrow or surrender of any Company securities.

                    (e)  In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                    (f)  Notify each Holder of Registrable Securities covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing. If, in
such event, the Company advises the Holders of the Registrable Securities
covered by such registration statement that the Company considers it appropriate
for the registration statement to be amended, the Holders of such securities
shall suspend any further sales of their registered shares until the Company
advises them that the registration statement has been amended and the Company
has delivered revised prospectuses to the selling Holders (the selling Holders
shall promptly return to the Company all prior prospectuses). The time periods
referred to in this Section 1 shall be extended for an additional number of
business days during which the rights to sell shares was suspended.

                                       6
<PAGE>
 
                    (g)  Cause all such Registrable Securities registered
pursuant hereunder to be listed on each securities exchange on which similar
securities issued by the Company are then listed.

                    (h)  Provide a transfer agent and registrar for all
Registrable Securities registered pursuant hereunder and a CUSIP number for all
such Registrable Securities, in each case not later than the effective date of
such registration.

                    (i)  Furnish, at the request of any Holder requesting
registration of Registrable Securities pursuant to this Section 1, on the date
that such Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Section 1, if such securities
are being sold through underwriters, or, if such securities are not being sold
through underwriters, on the date that the registration statement with respect
to such securities becomes effective, (i) an opinion, dated such date, of the
counsel representing the Company for the purposes of such registration, in form
and substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated such date, from
the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

             1.5.   Furnish Information.  It shall be a condition precedent to
                    ------------------- 
the obligations of the Company to take any action pursuant to this Section 1
with respect to the Registrable Securities of any selling Holder that such
Holder shall furnish to the Company such information regarding itself, the
Registrable Securities held by it, and the intended method of disposition of
such securities as shall be required to effect the registration of such Holder's
Registrable Securities.

             1.6.   Expenses of Demand Registration.  All expenses, other than
                    ------------------------------- 
underwriting discounts and commissions, incurred in connection with
registrations, filings or qualifications pursuant to Section 1.2, including
(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, and fees and disbursements of one counsel for the Holders
shall be borne by the Company; provided, however, that if a registration is
withdrawn at the request of the Holders requesting such registration (other than
as a result of information concerning a material adverse change to the business
or financial condition of the Company which is made known to the Holders after
the date on which such registration was requested) and if the requesting Holders
elect not to have such registration counted as a registration requested under
Section 1.2, the requesting Holders shall pay all of the expenses referred to
above of such registration pro rata in accordance with the number of their
Registrable Securities included in such registration in relation to the number
of shares of the Company and of others which were included in the registration.

             1.7.   Expenses of Company Registration. The Company shall bear and
                    -------------------------------- 
pay all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations

                                       7
<PAGE>
 
pursuant to Section 1.3 for each Holder (which right may be assigned as provided
in Section 1.13), including (without limitation) all registration, filing and
qualification fees, printers and accounting fees and fees and disbursements of
one counsel for the Holders relating or apportionable thereto selected by them,
but excluding solely underwriting discounts and commissions relating to
Registrable Securities.

             1.8.   Underwriting Requirements.  In connection with any offering 
                    ------------------------- 
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities sold that the
underwriters determine in their sole discretion is compatible with the success
of the offering, then the Company shall be required to include in the offering
only that number of such securities, including Registrable Securities, which the
underwriters determine in their sole discretion will not jeopardize the success
of the offering (the securities so included to be reduced, first, pro rata among
the holders of capital stock in their entirety, if necessary other than the
Holders; second, if necessary, the shares held by Garnick and the Viona
Employees pro rata; third, if necessary, among any other of the Holders other
than the holders of Class A Preferred Stock and Class B Preferred Stock; fourth,
if necessary, pro rata among the Holders of the Class A Preferred Stock and the
Class B Preferred Stock of the Company; next and lastly, if necessary, among the
Company's shares requested by the Company to be registered). For purposes of the
preceding parenthetical concerning apportionment, for any selling shareholder
which is a holder of Registrable Securities and which is a partnership or
corporation, the partners, retired partners and shareholders of such holder, or
the estates and family members of any such partners and retired partners and any
trusts for the benefit of any of the foregoing persons shall be deemed to be a
single "selling shareholder", and any pro-rata reduction with respect to such
"selling shareholder" shall be based upon the aggregate amount of shares
carrying registration rights owned by all entities and individuals included in
such "selling shareholder," as defined in this sentence.

             1.9.   Delay of Registration.  No Holder shall have any right to
                    --------------------- 
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

             1.10.  Indemnification.  In the event any Registrable Securities
                    --------------- 
are included in a registration statement under this Section 1:

                    (a)  The Company will indemnify and hold harmless each
Holder, any underwriter (as defined in the Act) for such Holder and each person,
if any, who controls such Holder or underwriter within the meaning of the Act or
the 1934 Act, against any losses, claims, damages, or liabilities (joint or
several) to which they may become subject under the Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereof) arise out of or are based upon any of the
following statements, 

                                       8
<PAGE>
 
omissions or violations (collectively a "Violation"): (i) any untrue statement
or alleged untrue statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein not misleading, or (iii) any violation
or alleged violation by the Company of the Act, the 1934 Act, any state
securities law or any rule or regulation promulgated under the Act, the 1934 Act
or any state securities law; and the Company will pay to each such Holder,
underwriter or controlling person, as incurred, any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
indemnity obligations of the Company contained in this subsection 1.10(a) shall
not apply (x) to amounts paid in settlement of any such loss, claim, damage,
liability, or action if such settlement is effected without the consent of the
Company (which consent shall not be unreasonably withheld), (y) in any such case
for any such loss, claim, damage, liability, or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person,
and (z) with respect to a Violation contained in or with respect to a
preliminary prospectus if a copy of the amended or supplemental preliminary
prospectus, or the final prospectus, shall have been delivered or sent to such
person within the time required by the Act, and the Violation was corrected in
such amended or supplemental preliminary prospectus or final prospectus.

                    (b)  Each selling Holder will indemnify and hold harmless
the Company, each of its directors, each of its officers, each person, if any,
who controls the Company within the meaning of the Act or the 1934 Act, any
underwriter, any other Holder selling securities in such registration statement
and any controlling person of any such underwriter or other Holder, against any
losses, claims, damages, or liabilities (joint or several) to which any of the
foregoing persons may become subject, under the Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages, or liabilities
(or actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs in
reliance upon and in conformity with written information furnished by such
Holder expressly for use in connection with such registration; and each such
Holder will pay any legal or other expenses reasonably incurred by any person
intended to be indemnified pursuant to this subsection 1.10(b), in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement of the Company contained
in this subsection 1.10(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; and provided further, the total amount for which any Holder shall be
liable shall not in any event exceed the lesser of (A) aggregate net proceeds
received by such Holder from the sale of Registrable Securities held by such
Holder in such registration and (B) in the event that the underwriter shall
require joint and several liability of the selling Holders, that portion of
aggregate losses, claims, damages, liabilities or expenses indemnified against
as is equal to the proportion of the total number of Registrable Securities
being sold by such Holder to the total number of shares of Common Stock being
sold by the Company and all persons for which shares are registered in such
offering; and provided further, however, that no Holder shall be required to

                                       9
<PAGE>
 
enter into an Underwriting Agreement that provides for any greater potential
liability than as set forth herein.

                    (c)  Promptly after receipt by an indemnified party under
this Section 1.10 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.10, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties (the consent of the indemnified party to such
counsel not to be unreasonably withheld); provided, however, that an indemnified
party (together with all other indemnified parties which may be represented
without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.10, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.10.

                    (d)  If the indemnification provided for in this Section
1.10 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

                    (e)  Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

                    (f)  The obligations of the Company and Holders under this
Section 1.10 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

                -------- 
benefits of Rule 144 promulgated under the Act and any other rule or regulation
of the SEC that may at any time permit a Holder to sell securities of the
Company to the public without registration or pursuant to a registration on Form
S-3, the Company agrees to:

                (a) make and keep public information available, as those terms
are understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public;

                (b) take such action, including the voluntary registration of
its Common Stock under Section 12 of the 1934 Act, as is necessary to enable the
Holders to utilize Form S-3 for the sale of their Registrable Securities, such
action to be taken as soon as practicable after the end of the fiscal year in
which the first registration statement filed by the Company for the offering of
its securities to the general public is declared effective;

                (c) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

                (d) furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144 (at
any time after ninety (90) days after the effective date of the first
registration statement filed by the Company), the Act and the 1934 Act (at any
time after it has become subject to such reporting requirements), or that it
qualifies as a registrant whose securities may be resold pursuant to Form S-3
(at any time after it so qualifies), (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

         1.12.  Form S-3 Registration.  In case the Company shall receive from
                ---------------------
any Holder or Holders holding at least fifty percent (50%) of the Registrable
Securities then outstanding a written request or requests that the Company
effect a registration on Form S-3 and any related qualification or compliance
with respect to all or a part of the Registrable Securities owned by such Holder
or Holders but in no event less than 25% of the originally issued Class B
Preferred Stock, the Company will:

                (a) promptly give written notice of the proposed registration,
and any related qualification or compliance, to all other Holders; and

                (b) effect, as soon as practicable, such registration and all
such qualifications and compliances as may be so requested and as would permit
or facilitate the sale and distribution of all or such portion of such Holder's
or Holders' Registrable Securities as are specified in such request, together
with all or such portion of the Registrable Securities of any other Holder or
Holders joining in such request as are specified in a written request given
within fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance,

                                       11
<PAGE>
 
pursuant to this Section 1.12: (1) if Form S-3 is not available for such
offering by the Holders; (2) if the Company shall furnish to the Holders a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company, the filing of such Form
S-3 Registration would (A) interfere with or affect the negotiation or
completion of any material transaction that is being contemplated by the Company
or (B) involve initial or continuing disclosure obligations materially adverse
to the best interests of the Company's shareholders, and it is therefore
essential to defer the filing of such registration statement, in which event the
Company shall have the right to defer the filing of the Form S-3 registration
statement for a period of not more than sixty (60) days after receipt of the
request of the Holder or Holders under this Section 1.12; provided, however,
that the Company shall not utilize this right more than once in any twelve (12)
month period; or (3) in any particular jurisdiction in which the Company would
be required to qualify to do business or to execute a general consent to service
of process in effecting such registration, qualification or compliance.

                (c) Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders. All expenses incurred in connection with a
registration requested pursuant to Section 1.12, including (without limitation)
all registration, filing, qualification, printer's and accounting fees and the
fees and disbursements of one counsel for the Holders, but excluding solely any
underwriters' discounts or commissions, shall be borne by the Company.
Registrations effected pursuant to this Section 1.12 shall not be counted as
demands for registration or registrations effected pursuant to Sections 1.2 or
1.3.

                (d) The Company shall not be obligated to effect any
registration pursuant to this Section 1.12 if the Company delivers to the
Holders requesting registration under this Section 1.12 an opinion, in form and
substance acceptable to such Holders, of counsel satisfactory to such Holders,
that the Registrable Securities so requested to be registered may be sold or
transferred pursuant to Rule 144(k) under the Act.

         1.13.  Assignment of Registration Rights.  The rights to cause the
                ---------------------------------
Company to register Registrable Securities pursuant to this Section 1 may be
assigned by a Holder to a transferee or assignee of such securities provided
that the Company is given a written notice at the time of or within a reasonable
time after such transfer or assignment, stating the name and address of the
transferee or assignee and identifying the securities with respect to which such
registration rights are being transferred or assigned, and, provided further,
that the transferee or assignee of such rights assumes the obligations of such
Holder under this Section 1.

         1.14.  Limitations on Subsequent Registration Rights.  From and after
                --------------------------------------------- 
the date of this Agreement, the Company shall not, without the prior written
consent of the Holders of a majority of the outstanding Registrable Securities,
enter into any agreement with any holder or prospective holder of any securities
of the Company which would allow such holder or prospective holder (a) to
include such securities in any registration filed under Section 1.2 hereof,
unless under the terms of such agreement, such holder or prospective holder may
include such securities in any such registration only to the extent that the
inclusion of such holder's securities will not reduce the amount of the
Registrable Securities of the Holders which is included or (b) to make a demand
registration which could result in such registration statement

                                       12
<PAGE>
 
being declared effective prior to the earlier of either of the dates set forth
in subsection 1.2(a) or within one hundred twenty (120) days of the effective
date of any registration effected pursuant to Section 1.2.

         1.15.  "Market Stand-Off" Agreement.  Each Investor and Existing
                ----------------------------
Investor hereby agrees that, during the period of duration specified by the
Company and an underwriter of Common Stock or other securities of the Company,
following the effective date of a registration statement of the Company filed
under the Act, it shall not, to the extent requested by the Company and such
underwriter, directly or indirectly sell, offer to sell, contract to sell
(including, without limitation, any short sale), grant any option to purchase or
otherwise transfer or dispose of (other than to donees who agree to be similarly
bound) any securities of the Company held by it at any time during such period
except Common Stock included in such registration; provided, however, that:

                (a) such agreement shall be applicable as to the period
immediately following the first such registration statement of the Company which
covers Common Stock to be sold on its behalf to the public in an underwritten
offering;

                (b) all officers, directors and founders of the Company, all
then existing two percent or greater shareholders of the Company and all other
persons with registration rights (whether or not pursuant to this Agreement)
enter into similar agreements; and

                (c) such market stand-off time period shall not exceed one
hundred eighty (180) days.

         In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of each
Investor and Existing Investor (and the shares or securities of every other
person subject to the foregoing restriction) until the end of such period.

         Notwithstanding the foregoing, the obligations described in this
Section 1.15 shall not apply to a registration relating solely to employee
benefit plans on Form S-l or Form S-8 or similar forms which may be promulgated
in the future, or a registration relating solely to a Commission Rule 145
transaction on Form S-4 or similar forms which may be promulgated in the future.

         1.16.  1934 Act.  As promptly as possible following receipt of a
                --------
written request therefor from the holders of 50% of the outstanding Registrable
Securities at any time while the Company either (a) is subject to periodic
reporting pursuant to Section 15(d) of the Exchange Act or (b) has 500 or more
shareholders of record, the Company shall register its Common Stock under
Section 12 of the 1934 Act, arrange for its Common Stock to be listed on a
national stock exchange or included for quotation on the Nasdaq National Market,
as requested, and shall keep effective such registration and maintain such
listing or inclusion, and shall use its best efforts timely to file such
information, documents and reports as the Securities and Exchange Commission may
require or prescribe that the Company file in connection therewith. The Company
will, at the request of any holder of Registrable Securities, advise such holder
in writing as to whether all reports required to be filed by the Company under
Section 13 of the

                                       13
<PAGE>
 
1934 Act during the 12 months preceding such request (or for such shorter period
as the Company was required to file such reports) have been filed, and any other
information which the holder may reasonably require in order to comply with Rule
144, or any other comparable rule, as then in effect.

     FOR VALUE RECEIVED, QUADRANT INTERNATIONAL, INC., a Pennsylvania
corporation (the "Company"), promises to issue to Progress Capital, Inc., a
Pennsylvania corporation, or any successor entity ("Progress"), seventy-five
thousand (75,000) fully paid and non-assessable shares of the Company's voting
common stock for the price of $0.593 per share (the "Purchase Price"). The
holder of this Warrant Certificate shall have the right to exercise the rights
provided for herein (such rights, with respect to each such share, is called
herein a "Warrant" and with respect to more than one share, is called herein
"Warrants"), whole or in part at any time or times until June in 26, 2004. The
number of shares of common stock purchasable upon exercise of the Warrants and
the Purchase Price shall be subject to adjustment from time to time as set forth
herein.

     1.  Definitions.  For purposes of this Warrant Certificate:
         -----------                                            

         (a) "Common Stock" shall mean, in addition to the classes of common
              ------------                                                  
stock now in existence, any and all other stock of any class which has the right
to participate in the 
<PAGE>
 
distribution of earnings and assets of the Company without
limit as to amount or percentage.  "Common Stock" shall not include any shares
at any time directly or indirectly owned by the Company.

         (b) "Warrant" shall mean the right given under this Warrant
              -------                                               
Certificate to purchase one share of the Company's voting common stock.

         (c) "Warrant Shares" shall mean the shares of the Company's voting
              --------------                                               
common stock purchased upon exercise of Warrants or which the holder hereof has
the right to purchase upon exercise of Warrants.

     2.  Exercise of Warrants.
         -------------------- 

         (a) Warrants may be exercised in whole or in part by the surrender of
this Warrant Certificate, properly endorsed, accompanied by written notice to
the Company by execution of the form of subscription attached hereto, at the
principal executive office of the Company and upon payment to the Company by
certified check or bank draft of the Purchase Price for the shares purchasable
thereunder. The persons entitled to the shares so purchased shall be treated for
all purposes as the holders of such shares as of the close of business on the
date of exercise. Certificates for the Warrant Shares so purchased together with
a new Warrant Certificate or Certificates of like tenor representing in the
aggregate the right to purchase the number of shares of the Company's common
stock with respect to which Warrants have not been exercised (each such Warrant
Certificate or Certificates to be for such portion of the total shares as the
holder thereof shall designate), shall be issued and delivered to the persons so
entitled within a reasonable time, not exceeding 15 days, after such exercise.

         (b) Until such time as a Warrant is exercised in whole or in part, the
holder thereof shall have no rights as a shareholder of the Company except for
such rights as are expressly set forth herein.

     3.  Exchange.  This Warrant Certificate is exchangeable, upon the surrender
         --------                                                     
thereof by the holder thereof at any office of the Company, for a new Warrant
Certificate of like tenor representing in the aggregate the right to purchase
the number of shares of the Company's voting common stock purchasable under the
Warrant Certificate being exchanged, each such new Warrant Certificate to
represent the right to subscribe for and purchase such portion of the aggregate
number of shares of the Company's voting common stock represented by the Warrant
Certificate being exchanged as shall be designated by such holder at the time of
such surrender.

     4.  Transfer.
         -------- 

         (a) This Warrant Certificate and the Warrants are transferable, in
whole or in part, at the principal executive offices of the Company by the
Holder hereof in person or by duly authorized attorney, upon presentation of
this Warrant Certificate properly endorsed for transfer; provided, however that
                                                         --------  -------     
this Warrant Certificate and the Warrants are only so transferable to a legal
successor of Progress or a corporate affiliate of Progress or Progress Bank.

         (b) Progress acknowledges by acceptance of this Warrant Certificate
that the Warrant Shares may be sold only if the Warrant Shares are registered
under federal and state 

                                       2
<PAGE>
 
securities laws or if an exemption from registration is available. The Warrant
Shares presently are not so registered, and the Company is under no obligation
at any time to register them under federal or state securities laws, except as
expressly provided in this Warrant Certificate. Each certificate representing
Warrant Shares shall bear a legend substantially the same as the legend set
forth on the first page of this Warrant Certificate.

     5.  Certain Covenants of the Company.  The Company covenants and agrees
         --------------------------------                                   
that all Warrant Shares will, upon issuance, be duly and validly issued, fully
paid and nonassessable, and free from all taxes, liens, and charges with respect
to the issuance thereof provided that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any certificate in a name other than Progress; and, if any other
outstanding shares of Common Stock are then listed on a national or regional
securities exchange, will be so listed. The Common Stock is not presently listed
on any securities exchange and the Company is under no obligation to list it.
The Company further covenants and agrees that during the period within which the
rights represented by this Warrant Certificate may be exercised, the Company
shall, at all times, have authorized and reserved for the purpose of issuance
upon exercise of the purchase rights evidenced by this Warrant Certificate, a
sufficient number of shares of the Company's common stock to provide for the
then exercise of the rights represented by this Warrant Certificate.

     6.  Adjustment of Purchase Price and Number of Shares.  The number of
         -------------------------------------------------                
Warrant Shares purchasable hereunder and the Purchase Price shall be subject to
adjustment from time to time upon the happening of certain events as follows:

         (a) Reclassification, Consolidation or Merger.  In case of any
             -----------------------------------------                 
reclassification (other than a change in par value or from par value to no par
value) or change of outstanding securities issuable upon exercise of this
Warrant Certificate, or in case of any consolidation or merger of the Company
with or into another corporation (other than a merger with another corporation
in which the Company is a continuing corporation and which does not result in
any such reclassification or change), the Company, or such successor or
purchasing corporation, as the case may be, shall, without payment of any
additional consideration therefor, execute and deliver to each holder of
Warrants, a new Warrant Certificate, providing that the holder of such new
Warrant Certificate shall have the right to exercise such new Warrant
Certificate (upon terms no less favorable to the holder than those then
applicable to this Warrant Certificate) and procure upon such exercise in lieu
of each share of the Company's voting common stock theretofore issuable upon
exercise of the Warrants the kind and amount of shares of stock, other
securities, money or property (the "Consideration") receivable upon such
reclassification, change, consolidation, or merger, by the holder of one share
of the Company's voting common stock issuable upon exercise of the Warrants as
though this Warrant Certificate had been exercised immediately prior to such
reclassification, change, consolidation or merger. Such new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 6. The provisions of
this Section 6(a) shall similarly apply to successive reclassifications,
changes, consolidations or mergers. The Company shall use its best efforts to
give Progress no less than 30 days prior written notice of any reclassification,
change of outstanding securities, merger or consolidation described in this
Section 6(a).

                                       3
<PAGE>
 
         (b) Subdivision or Combination of Shares.  If the Company, at any time
             ------------------------------------                              
while any Warrants remain outstanding and unexpired, shall subdivide or combine
any of its Common Stock, the Purchase Price shall be proportionately reduced and
the number of Warrant Shares purchasable hereunder proportionately increased, in
the case of a subdivision of shares, or vice versa in the case of a combination
of shares, in either case as of the effective date of such subdivision or
combination.

         (c) Certain Dividends and Distributions.  If at any time while any
             -----------------------------------                           
Warrants are outstanding and unexpired the Company shall:

             (i) Pay a dividend payable in its Common Stock, or in rights to
acquire (by exercise, conversion or otherwise) its Common Stock, (in each case
other than where shares are being issued in lieu of cash), then the number of
Warrants shall be adjusted as of the date of such dividend, by multiplying the
number of Warrants represented by this Warrant Certificate immediately prior to
such date by a fraction (I) the numerator of which shall be the total number of
shares of Common Stock outstanding immediately after such dividend and (II) the
denominator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend; or

             (ii) Authorize a distribution of its assets to the holders of its
Common Stock as a dividend in liquidation or by way of return of capital or
other than as a dividend payable out of earnings or surplus legally available
for dividends under applicable law, the Company shall give notice thereof to the
holder of this Warrant Certificate at least 30 days prior to the record date for
determining entitlement to such distribution; and the holder of this Warrant
Certificate shall, upon exercise of the Warrants, be entitled to participate in
such distribution, without payment of any additional consideration therefor,
according to the number of shares of Common Stock held by such holder after the
exercise of the Warrants pro rata with all other holders of the Company's Common
Stock.

         (d) Adjustment of Purchase Price.  Upon each adjustment of the number
             ----------------------------                                     
of shares of the Company's voting common stock purchasable hereunder, the
Purchase Price then in effect shall likewise be adjusted to that amount
determined by multiplying the Purchase Price then in effect by a fraction the
number of which is the number of shares of the Company's voting common stock
purchasable hereunder immediately prior to the adjustment and the denominator of
which is the number of shares of the Company's voting common stock purchasable
hereunder immediately after such adjustment.

         (e) Other Action Affecting Common Stock.  If any event occurs as to
             -----------------------------------                            
which the other provisions of this Section 6 are not strictly applicable, or if
strictly applicable would not fairly protect the holder of Warrants against
dilution in accordance with the intent and principles of such Section 6, then
the Board of Directors shall make an adjustment in the application of such
provisions, in accordance with such intent and principles, so as to protect such
anti-dilution rights as aforesaid.

     7.  Notice of Adjustments.  In the event the Company shall take any action
         ---------------------                                                 
which pursuant to Section 6 results in an adjustment of the Purchase Price
and/or the number of Warrant Shares purchasable upon exercise of Warrants, the
Company will give to each holder of 

                                       4
<PAGE>
 
Warrants written notice of such action promptly following its effective date.
Such notice shall contain the Company's certificate signed by its President
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated
(including a description of the basis on which the Company's Board of Directors
made any determination hereunder), and the Purchase Price and number of Warrant
Shares purchasable after giving effect to such adjustment. Failure to give any
notice required by this Warrant Certificate shall not effect the validity of any
action taken that triggers an adjustment under Section 6.

     8.  Participation Rights.  Other than in connection with a public
         --------------------                                         
offering, if an unaffiliated third party makes an offer to the holders of more
than 50% of the outstanding shares of Common Stock of the Company (the "Offer")
to acquire, whether by purchase (including a merger or consolidation), tender or
exchange, in excess of 50% of the outstanding shares of Common Stock of the
Company on a fully diluted basis, which Offer such holders desire to accept, the
Company agrees to promptly forward a copy of the Offer to Progress. In such
event, the Company agrees not to effect any consolidation or merger to which it
would be a party and to use its best efforts to cause any such other transaction
with the shareholders not to be consummated, unless Progress shall have had a
period of at least ten days from the date it received a copy of the offer to
exercise this Warrant and participate in the transaction to the same extent, on
a pro rata basis, with the other shareholders of the Company. Progress
acknowledges that the rights granted hereunder have also been granted to other
security holders of the Company and understands that such rights may be junior
or pari passu with the rights of such other parties.

     9.  No Registration under Securities Act.  Neither this Warrant Certificate
         ------------------------------------                       
nor the Warrant Shares have been registered under the Securities Act of 1933, as
amended (the "Act") or under the securities laws of any state. In issuing this
Warrant Certificate, the Company has relied upon the exemption from registration
provided by Section 4(2) of the Act for transactions by an issuer not involving
any public offering. The holder of this Warrant Certificate acknowledges by
acceptance of this Warrant Certificate that the sale of Warrants, or of any of
the Warrant Shares, under certain circumstances may be deemed to constitute a
distribution within the meaning of, and require registration under, the Act.

     10. Subsequent Registration by Company of the Securities.
         ---------------------------------------------------- 

         (a) As used herein, the term "Registrable Security" means each of the
shares of Common Stock issuable upon exercise of this Warrant and any shares of
Common Stock issued upon any stock split or stock dividend in respect of such
shares; provided, however, that Registerable Security shall not include any such
        --------  -------                                                       
shares (i) disposed of pursuant to one or more registration statements under the
Act, (ii) which are saleable pursuant to Rule 144 under the Act or (iii) which
have otherwise been sold or transferred without registration under the Act.

         (b) If the Company shall seek to register under the Act or qualify any
of its Common Stock (except in connection with or an acquisition, merger or
exchange of stock, to be registered on Forms S-4, S-8 or any successor forms
under the Act) and if the form of registration statement proposed to be used
otherwise may be used for the registration of the Registerable Securities, then,
on each such occasion, the Company shall furnish the holders of 

                                       5
<PAGE>
 
Registerable Securities (including the holders of Warrants exercisable for
Registrable Securities) with at least 30 days prior written notice thereof. At
the written request of any such holders, given within 20 days after the receipt
of such notice, and subject to the provisions of the Registration Rights
Agreement dated April 30, 1998 between the Company and several holders of its
securities (the "Registration Rights Agreement"), the Company will use its best
efforts to cause all of the Registerable Securities for which registration shall
have been so requested to be included in such registration statement. In the
event that the proposed registration by the Company is, in whole or in part, an
underwritten public offering, and the managing underwriter determines and
advises in writing that the securities requested to be included in such
registration exceeds the number which can be sold in such offering, the Company
will include in such registration, in the following order of priority: (i)
first, the securities the Company proposes to register (which triggers this
Section 10), whether for its own account or for the account of any of its
securityholders who have Registrable Securities under and as defined in the
Registration Rights Agreement; (ii) second, the Registrable Securities and the
securities of any other securityholders of the Company (including, but not
limited to, NEPA Venture Fund II, L.P. to the extent it exercises its piggyback
registration rights) with rights equal to those of the holders of Registrable
Securities, pro rata (based on the number of fully diluted shares of the Company
then owned by such holders), and (iii) third, other securities requested to be
included in such registration statement.

         (c) All expenses in connection with the preparation and filing of any
registration statement under this Section 10, any registration or qualification
under securities or blue Sky laws of states in which the offering will be made
under such registration statement, and any filing fee of the National
Association of Securities Dealers, Inc. relating to such offering, shall be
borne in full by the Company, except for (i) any underwriter's or broker's
commissions applicable to the shares to be sold by the holders of Registerable
Securities, (ii) fees required to be paid by a selling shareholder rather than
the Company in order to comply with Blue Sky or state securities laws, (iii) all
fees or expenses expressly applicable to securities being sold by the holders of
Registrable Securities and (iv) fees or expenses of such holder's counsel.

         (d) The Company shall indemnify and hold harmless selling holders of
Registrable Securities and, to the extent required in any agreement with any
underwriter or broker-dealer for whom the Registerable Securities may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Act) against all
losses, claims, damages, liabilities, expenses or actions in respect thereof
caused by any untrue statement of a material fact contained in any registration
statement under which such Registerable Securities were registered under the
Act, any preliminary or final prospectus contained therein, or any amendment or
supplement thereto (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registerable
Securities that are subject to a claimed right of indemnification) or caused by
any omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading (unless cured by an
amendment or supplement to the prospectus delivered to the selling holders prior
to the sales of the registerable securities that are subject to a claimed right
or indemnification); except insofar as such losses, claims, damages, liabilities
or expenses are caused by any untrue statement or omission contained in
information furnished in writing to the Company by the selling holders of
Registrable Securities expressly for use therein. In connection with any such
registration statement, the selling holders of Registrable 

                                       6
<PAGE>
 
Securities will furnish the Company in writing such information as the Company
may reasonably request for use in any such registration statement or prospectus
and they will, as a condition precedent to the Company's obligation hereunder,
agree to indemnify the Company, its directors and officers, and, to the extent
required in any agreement with any underwriter or broker-dealer, each such
underwriter or broker-dealer and each person, if any, who controls the Company
or any underwriter or broker-dealer (within the meaning of the Act) against any
loses, claims, damages, liabilities, statement of a material fact contained in
any such registration statement or prospectus or caused by any omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein no misleading, insofar as such losses, claims, damages,
liabilities, expenses or actions are caused by any untrue statement or omission
based upon information furnished in writing to the Company by the selling
holders expressly for use therein.

         (e) If a public offering is not completed within nine months after the
effective date of any registration statement filed by the Company pursuant to
Section 10(b), the Company reserves the right, in its option, to withdraw from
registration any securities offered by the Company which have not been sold
during such period.

         (f) Notwithstanding the foregoing, the Company reserves the right to
delay such registration, or to withhold efforts to cause the registration
statement to become effective, if the Company determines in good faith that such
registration might (i) interfere with or affect the negotiation or completion of
any transaction that is being contemplated by the Company, or (ii) involve
initial or continuing disclosure obligations that might not be in the best
interest of the Company's shareholders. The selling holders of Registrable
Securities, upon receipt of notice from the Company that an event has occurred
which requires a post-effective amendment to any registration statement or
supplement to the prospectus included therein, shall promptly discontinue the
sale of their Registerable Securities until they receive a copy of a
supplemented or amended prospectus from the Company, which the Company shall
provide as soon as practicable after such notice.

         (g) The Company shall have the right to grant any registration rights
or register any securities for the account of any person other than holders of
Registerable Securities regardless of whether such rights are senior,
subordinate or equal to those of the holders of Registerable Securities.

         (h) In the case of any registration initiated under this Section 10,
the Company shall have the right to designate the managing underwriter in any
underwritten offering. The Company will supply the selling holders of
Registrable Securities with copies of such registration statements and of the
prospectus included therein in such quantities as may be reasonably necessary
for the purpose of the proposed disposition.

     11. Sale of Warrant Shares Without Registration.  The holder of this
         -------------------------------------------                     
Warrant Certificate, by acceptance hereof, and the holder of any Warrant Shares,
by acceptance thereof, agrees to give written notice to Company of such holder's
intention before selling or otherwise disposing of the Warrant Shares, except to
the extent that such sale is pursuant to a then effective registration
statement. Such notice shall describe briefly the manner of any proposed sale or
other disposition to be made of Warrant Shares. Such notice shall be accompanied
by an opinion 

                                       7
<PAGE>
 
of counsel reasonably satisfactory to the Company stating that the proposed
exercise or sale or other disposition may be effected without registration or
qualification (under any federal or state law) of Warrant Shares. The Company,
as promptly as practicable, shall notify such holder if such opinion is
satisfactory, whereupon such holder shall be entitled to sell or otherwise
dispose of the Warrant Shares or to receive the certificates representing the
shares of Common Stock or to receive the certificates representing the Warrant
Shares and dispose of the shares so received, all in accordance with the terms
of the notice of intent delivered by such holder to the Company and in
accordance with all other applicable terms and conditions contained herein.

         --------------------------------------                              
reasonable evidence satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of a Warrant Certificate and (in the case of loss,
theft, or destruction) of reasonable indemnity and (in the case of mutilation)
upon surrender and cancellation thereof, the Company will execute and deliver,
in lieu thereof, a new Warrant Certificate of like tenor.

     13. Notices.  All notices, requests and demands to or upon the Company 
         -------

     FOR VALUE RECEIVED, QUADRANT INTERNATIONAL, INC., a Pennsylvania
corporation (the "Company"), promises to issue to Progress Capital, Inc., a
Pennsylvania corporation, or any successor entity ("Progress"), two hundred
thousand (200,000) fully paid and non-assessable shares of the Company's voting
common stock for the price of $0.593 per share (the "Purchase Price").  The
holder of this Warrant Certificate shall have the right to exercise the rights
provided for herein (such rights, with respect to each such share, is called
herein a "Warrant" and with respect to more than one share, is called herein
"Warrants"), in whole or in part at any time or times until January 6, 2005.
The number of shares of common stock purchasable upon exercise of the Warrants
and the Purchase Price shall be subject to adjustment from time to time as set
forth herein.

     1.   Definitions.  For purposes of this Warrant Certificate:
          -----------                                            

          (a)  "Common Stock" shall mean, in addition to the classes of common
                ------------                                                  
stock now in existence, any and all other stock of any class which has the right
to participate in the distribution of earnings and assets of the Company without
limit as to amount or percentage.  
<PAGE>
 
"Common Stock" shall not include any shares at any time directly or indirectly
owned by the Company.
 
          (b)  "Warrant" shall mean the right given under this Warrant
                -------                                               
Certificate to purchase one share of the Company's voting common stock.

          (c)  "Warrant Shares" shall mean the shares of the Company's voting
                --------------                                               
common stock purchased upon exercise of Warrants or which the holder hereof has
the right to purchase upon exercise of Warrants.

     2.   Exercise of Warrants.
          -------------------- 

          (a)  Warrants may be exercised in whole or in part by the surrender of
this Warrant Certificate, properly endorsed, accompanied by written notice to
the Company by execution of the form of subscription attached hereto, at the
principal executive office of the Company and upon payment to the Company by
certified check or bank draft of the Purchase Price for the shares purchasable
thereunder.  The persons entitled to the shares so purchased shall be treated
for all purposes as the holders of such shares as of the close of business on
the date of exercise.  Certificates for the Warrant Shares so purchased together
with a new Warrant Certificate or Certificates of like tenor representing in the
aggregate the right to purchase the number of shares of the Company's common
stock with respect to which Warrants have not been exercised (each such warrant
Certificate or Certificates to be for such portion of the total shares as the
holder thereof shall designate), shall be issued and delivered to the persons so
entitled within a reasonable time, not exceeding 15 days, after such exercise.

          (b)  Until such time as a Warrant is exercised in whole or in part,
the holder thereof shall have no rights as a shareholder of the Company except
for such rights as are expressly set forth herein.

     3.   Exchange.  This Warrant Certificate is exchangeable, upon the
          --------                                                     
surrender thereof by the holder thereof at any office of the Company, for a new
Warrant Certificate of like tenor representing in the aggregate the right to
purchase the number of shares of the Company's voting common stock purchasable
under the Warrant Certificate being exchanged, each such new Warrant Certificate
to represent the right to subscribe for and purchase such portion of the
aggregate number of shares of the Company's voting common stock represented by
the Warrant Certificate being exchanged as shall be designated by such holder at
the time of such surrender.

     4.   Transfer.
          -------- 

          (a)  This Warrant Certificate and the Warrants are transferable, in
whole or in part, at the principal executive offices of the Company by the
Holder hereof in person or by duly authorized attorney, upon presentation of
this Warrant Certificate properly endorsed for transfer; provided, however that
                                                         --------  -------     
this Warrant Certificate and the Warrants are only so transferable to a legal
successor of Progress or a corporate affiliate of Progress or Progress Bank.

          (b)  Progress acknowledges by acceptance of this Warrant Certificate
that the Warrant Shares may be sold only if the Warrant Shares are registered
under federal and state securities laws or if an exemption from registration is
available.  The Warrant Shares presently 

                                       2
<PAGE>
 
are not so registered, and the Company is under no obligation at any time to
register them under federal or state securities laws, except as expressly
provided in this Warrant Certificate. Each certificate representing Warrant
Shares shall bear a legend substantially the same as the legend set forth on the
first page of this Warrant Certificate.

     5.   Certain Covenants of the Company.  The Company covenants and agrees
          --------------------------------                                   
that all Warrant Shares will, upon issuance, be duly and validly issued, fully
paid and nonassessable, and free from all taxes, liens, and charges with respect
to the issuance thereof provided that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any certificate in a name other than Progress; and, if any other
outstanding shares of Common Stock are then listed on a national or regional
securities exchange, will be so listed.  The Common Stock is not presently
listed on any securities exchange and the Company is under no obligation to list
it.  The Company further covenants and agrees that during the period within
which the rights represented by this Warrant Certificate may be exercised, the
Company shall, at all times, have authorized and reserved for the purpose of
issuance upon exercise of the purchase rights evidenced by this Warrant
Certificate, a sufficient number of shares of the Company's common stock to
provide for the then exercise of the rights represented by this Warrant
Certificate.

     6.   Adjustment of Purchase Price and Number of Shares.  The number of
          -------------------------------------------------                
Warrant Shares purchasable hereunder and the Purchase Price shall be subject to
adjustment from time to time upon the happening of certain events as follows:

          (a)  Reclassification, Consolidation or Merger.  In case of any
               -----------------------------------------                 
reclassification (other than a change in par value or from par value to no par
value) or change of outstanding securities issuable upon exercise of this
Warrant Certificate, or in case of any consolidation or merger of the Company
with or into another corporation (other than a merger with another corporation
in which the Company is a continuing corporation and which does not result in
any such reclassification or change), the Company, or such successor or
purchasing corporation, as the case may be, shall, without payment of any
additional consideration therefor, execute and deliver to each holder of
Warrants, a new Warrant Certificate, providing that the holder of such new
Warrant Certificate shall have the right to exercise such new Warrant
Certificate (upon terms no less favorable to the holder than those then
applicable to this Warrant Certificate) and procure upon such exercise in lieu
of each share of the Company's voting common stock theretofore issuable upon
exercise of the Warrants the kind and amount of shares of stock, other
securities, money or property (the "Consideration") receivable upon such
reclassification, change, consolidation, or merger, by the holder of one share
of the Company's voting common stock issuable upon exercise of the Warrants as
though this Warrant Certificate had been exercised immediately prior to such
reclassification, change, consolidation or merger.  Such new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 6. The provisions of
this Section 6(a) shall similarly apply to successive reclassifications,
changes, consolidations or mergers.  The Company shall use its best efforts to
give Progress no less than 30 days prior written notice of any reclassification,
change of outstanding securities, merger or consolidation described in this
Section 6(a).

                                       3
<PAGE>
 
          (b)  Subdivision or Combination of Shares. If the Company, at any time
               ------------------------------------                          
while any Warrants remain outstanding and unexpired, shall subdivide or combine
any of its Common Stock, the Purchase Price shall be proportionately reduced and
the number of Warrant Shares Purchasable hereunder proportionately increased, in
the case of a subdivision of shares, or vice versa in the case of a combination
of shares, in either case as of the effective date of such subdivision or
combination.

          (c)  Certain Dividends and Distributions.  If at any time while any
               -----------------------------------                           
Warrants are outstanding and unexpired the Company shall:

               (i)  Pay a dividend payable in its Common Stock, or in rights to
acquire (by exercise, conversion or otherwise) its Common Stock, (in each case
other than where shares are being issued in lieu of cash), then the number of
Warrants shall be adjusted as of the date of such dividend, by multiplying the
number of Warrants represented by this Warrant Certificate immediately prior to
such date by a fraction (I) the numerator of which shall be the total number of
shares of Common Stock outstanding immediately after such dividend and (II) the
denominator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend; or

               (ii) Authorize a distribution of its assets to the holders of its
Common Stock as a dividend in liquidation or by way of return of capital or
other than as a dividend payable out of earnings or surplus legally available
for dividends under applicable law, the Company shall give notice thereof to the
holder of this Warrant Certificate at least 30 days prior to the record date for
determining entitlement to such distribution; and the holder of this Warrant
Certificate shall, upon exercise of the Warrants, be entitled to participate in
such distribution, without payment of any additional consideration therefor,
according to the number of shares of Common Stock held by such holder after the
exercise of the Warrants pro rata with all other holders of the Company's Common
Stock.

          (d)  Adjustment of Purchase Price.  Upon each adjustment of the number
               -----------------------------                                    
of shares of the Company's voting common stock purchasable hereunder, the
Purchase Price then in effect shall likewise be adjusted to that amount
determined by multiplying the Purchase Price then in effect by a fraction the
number of which is the number of shares of the Company's voting common stock
purchasable hereunder immediately prior to the adjustment and the denominator of
which is the number of shares of the Company's voting common stock purchasable
hereunder immediately after such adjustment.

          (e)  Other Action Affecting Common Stock.  If any event occurs as to
               -----------------------------------                            
which the other provisions of this Section 6 are not strictly applicable, or if
strictly applicable would not fairly protect the holder of Warrants against
dilution in accordance with the intent and principles of such Section 6, then
the Board of Directors shall make an adjustment in the application of such
provisions, in accordance with such intent and principles, so as to protect such
anti-dilution rights as aforesaid.

     7.   Notice of Adjustments.  In the event the Company shall take any action
          ---------------------                                                 
which pursuant to Section 6 results in an adjustment of the Purchase Price
and/or the number of Warrant Shares purchasable upon exercise of Warrants, the
Company will give to each holder of 

                                       4
<PAGE>
 
Warrants written notice of such action promptly following its effective date.
Such notice shall contain the Company's certificate signed by its President
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated
(including a description of the basis on which the Company's Board of Directors
made any determination hereunder), and the Purchase Price and number of Warrant
Shares purchasable after giving effect to such adjustment. Failure to give any
notice required by this Warrant Certificate shall not effect the validity of any
action taken that triggers an adjustment under Section 6.

     8.   Participation Rights.  Other than in connection with a public
          --------------------                                         
offering, if an unaffiliated third party makes an offer to the holders of more
than 50% of the outstanding shares of Common Stock of the Company (the "Offer")
to acquire, whether by purchase (including a merger or consolidation), tender or
exchange, in excess of 50% of the outstanding shares of Common Stock of the
Company on a fully diluted basis, which offer such holders desire to accept, the
Company agrees to promptly forward a copy of the Offer to Progress.  In such
event, the Company agrees not to effect any consolidation or merger to which it
would be a party and to use its best efforts to cause any such other transaction
with the shareholders not to be consummated, unless Progress shall have had a
period of at least ten days from the date it received a copy of the offer to
exercise this Warrant and participate in the transaction to the same extent, on
a pro rata basis, with the other shareholders of the Company.  Progress
acknowledges that the rights granted hereunder have also been granted to other
security holders of the Company and understands that such rights may be junior
or pari passu with the rights of such other parties.

     9.   No Registration under Securities Act.  Neither this Warrant
          ------------------------------------                       
Certificate nor the Warrant Shares have been registered under the Securities Act
of 1933, as amended (the "Act") or under the securities laws of any state.  In
issuing this Warrant Certificate, the Company has relied upon the exemption from
registration provided by Section 4(2) of the Act for transactions by an issuer
not involving any public offering.  The holder of this Warrant Certificate
acknowledges by acceptance of this Warrant Certificate that the sale of
Warrants, or of any of the Warrant Shares, under certain circumstances may be
deemed to constitute a distribution within the meaning of, and require
registration under, the Act.

     10.  Subsequent Registration by Company of the Securities.
          ---------------------------------------------------- 

          (a)  As used herein, the term "Registrable Security" means each of the
shares of Common Stock issuable upon exercise of this Warrant and any shares of
Common Stock issued upon any stock split or stock dividend in respect of such
shares; provided, however, that Registerable Security shall not include any such
        --------  -------                                                       
shares (i) disposed of pursuant to one or more registration statements under the
Act, (ii) which are saleable pursuant to Rule 144 under the Act or (iii) which
have otherwise been sold or transferred without registration under the Act.

          (b)  If the Company shall seek to register under the Act or qualify
any of its Common Stock (except in connection with or an acquisition, merger or
exchange of stock, to be registered on Forms S-4, S-8 or any successor forms
under the Act) and if the form of registration statement proposed to be used
otherwise may be used for the registration of the Registerable Securities, then,
on each such occasion, the Company shall furnish the holders of 

                                       5
<PAGE>
 
Registerable Securities (including the holders of Warrants exercisable for
Registrable Securities) with at least 30 days prior written notice thereof. At
the written request of any such holders, given within 20 days after the receipt
of such notice, and subject to the provisions of the Registration Rights
Agreement dated April 30, 1998 between the Company and several holders of its
securities (the "Registration Rights Agreement"), the Company will use its best
efforts to cause all of the Registerable Securities for which registration shall
have been so requested to be included in such registration statement. In the
event that the proposed registration by the Company is, in whole or in part, an
underwritten public offering, and the managing underwriter determines and
advises in writing that the securities requested to be included in such
registration exceeds the number which can be sold in such offering, the Company
will include in such registration, in the following order of priority: (i)
first, the securities the Company proposes to register (which triggers this
Section 10), whether for its own account or for the account of any of its
securityholders who have Registrable Securities under and as defined in the
Registration Rights Agreement; (ii) second, the Registrable Securities and the
securities of any other securityholders of the Company (including, but not
limited to, NEPA Venture Fund II, L.P. to the extent it exercises its piggyback
registration rights) with rights equal to those of the holders of Registrable
Securities, pro rata (based on the number of fully diluted shares of the Company
then owned by such holders), and (iii) third, other securities requested to be
included in such registration statement.

          (c)  All expenses in connection with the preparation and filing of any
registration statement under this Section 10, any registration or qualification
under securities or blue Sky laws of states in which the offering will be made
under such registration statement, and any filing fee of the National
Association of Securities Dealers, Inc. relating to such offering, shall be
borne in full by the Company, except for (i) any underwriter's or broker's
commissions applicable to the shares to be sold by the holders of Registerable
Securities, (ii) fees required to be paid by a selling shareholder rather than
the Company in order to comply with Blue Sky or state securities laws, (iii) all
fees or expenses expressly applicable to securities being sold by the holders of
Registrable Securities and (iv) fees or expenses of such holder's counsel.

          (d)  The Company shall indemnify and hold harmless selling holders of
Registrable Securities and, to the extent required in any agreement with any
underwriter or broker-dealer for whom the Registerable Securities may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Act) against all
losses, claims, damages, liabilities, expenses or actions in respect thereof
caused by any untrue statement of a material fact contained in any registration
statement under which such Registerable Securities were registered under the
Act, any preliminary or final prospectus contained therein, or any amendment or
supplement thereto (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registerable
Securities that are subject to a claimed right of indemnification) or caused by
any omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading (unless cured by an
amendment or supplement to the prospectus delivered to the selling holders prior
to the sales of the registerable securities that are subject to a claimed right
or indemnification); except insofar as such losses, claims, damages, liabilities
or expenses are caused by any untrue statement or omission contained in
information furnished in writing to the Company by the selling holders of
Registrable Securities expressly for use therein.  In connection with any such
registration statement, the selling holders of Registrable 

                                       6
<PAGE>
 
Securities will furnish the Company in writing such information as the Company
may reasonably request for use in any such registration statement or prospectus
and they will, as a condition precedent to the Company's obligation hereunder,
agree to indemnify the Company, its directors and officers, and, to the extent
required in any agreement with any underwriter or broker-dealer, each such
underwriter or broker-dealer and each person, if any, who controls the Company
or any underwriter or broker-dealer (within the meaning of the Act) against any
loses, claims, damages, liabilities, statement of a material fact contained in
any such registration statement or prospectus or caused by any omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein no misleading, insofar as such losses, claims, damages,
liabilities, expenses or actions are caused by any untrue statement or omission
based upon information furnished in writing to the Company by the selling
holders expressly for use therein.

          (e)  If a public offering is not completed within nine months after
the effective date of any registration statement filed by the Company pursuant
to Section 10(b), the Company reserves the right, in its option, to withdraw
from registration any securities offered by the Company which have not been sold
during such period.

          (f)  Notwithstanding the foregoing, the Company reserves the right to
delay such registration, or to withhold efforts to cause the registration
statement to become effective, if the Company determines in good faith that such
registration might (i) interfere with or affect the negotiation or completion of
any transaction that is being contemplated by the Company, or (ii) involve
initial or continuing disclosure obligations that might not be in the best
interest of the Company's shareholders. The selling holders of Registrable
Securities, upon receipt of notice from the Company that an event has occurred
which requires a post-effective amendment to any registration statement or
supplement to the prospectus included therein, shall promptly discontinue the
sale of their Registerable Securities until they receive a copy of a
supplemented or amended prospectus from the Company, which the Company shall
provide as soon as practicable after such notice.

          (g)  The Company shall have the right to grant any registration rights
or register any securities for the account of any person other than holders of
Registerable Securities regardless of whether such rights are senior,
subordinate or equal to those of the holders of Registerable Securities.

          (h)  In the case of any registration initiated under this Section 10,
the Company shall have the right to designate the managing underwriter in any
underwritten offering.  The Company will supply the selling holders of
Registrable Securities with copies of such registration statements and of the
prospectus included therein in such quantities as may be reasonably necessary
for the purpose of the proposed disposition.

     11.  Sale of Warrant Shares Without Registration.  The holder of this
          -------------------------------------------                     
Warrant Certificate, by acceptance hereof, and the holder of any Warrant Shares,
by acceptance thereof, agrees to give written notice to Company of such holder's
intention before selling or otherwise disposing of the Warrant Shares, except to
the extent that such sale is pursuant to a then effective registration
statement.  Such notice shall describe briefly the manner of any proposed sale
or other disposition to be made of Warrant Shares.  Such notice shall be
accompanied by an opinion 

                                       7
<PAGE>
 
of counsel reasonably satisfactory to the Company stating that the proposed
exercise or sale or other disposition may be effected without registration or
qualification (under any federal or state law) of Warrant Shares. The Company,
as promptly as practicable, shall notify such holder if such opinion is
satisfactory, whereupon such holder shall be entitled to sell or otherwise
dispose of the Warrant Shares or to receive the certificates representing the
shares of Common Stock or to receive the certificates representing the Warrant
Shares and dispose of the shares so received, all in accordance with the terms
of the notice of intent delivered by such holder to the Company and in
accordance with all other applicable terms and conditions contained herein.

     12.  Loss, Theft, Destruction or Mutilation.  Upon receipt by the Company
          --------------------------------------                              
of reasonable evidence satisfactory to it of the ownership of and the loss,
theft, destruction or mutilation of a Warrant Certificate and (in the case of
loss, theft, or destruction) of reasonable indemnity and (in the case of
mutilation) upon surrender and cancellation thereof, the Company will execute
and deliver, in lieu thereof, a new Warrant Certificate of like tenor.

GROSS PURCHASE PRICE:              $ 59,300


     FOR VALUE RECEIVED, QUADRANT INTERNATIONAL, INC., a Pennsylvania
corporation (the "Company"), promises to issue to Progress Capital, Inc., a
Pennsylvania corporation, or any successor entity ("Progress"), two hundred
thousand (200,000) fully paid and non-assessable shares of the Company's voting
common stock for the price of $0.593 per share (the "Purchase Price").  The
holder of this Warrant Certificate shall have the right to exercise the rights
provided for herein (such rights, with respect to each such share, is called
herein a "Warrant" and with respect to more than one share, is called herein
"Warrants"), in whole or in part at any time or times until seven (7) years
after the date hereof (as set forth on the signature page hereof).  The number
of shares of common stock purchasable upon exercise of the Warrants and the
Purchase Price shall be subject to adjustment from time to time as set forth

     1.   Definitions.  For purposes of this Warrant Certificate:
          -----------                                            

          (a)  "Common Stock" shall mean, in addition to the classes of common
                ------------                                                  
stock now in existence, any and all other stock of any class which has the right
to participate in the distribution of earnings and assets of the Company without
limit as to amount or percentage.  
<PAGE>
 
"Common Stock" shall not include any shares at any time directly or indirectly
owned by the Company.

          (b)  "Warrant" shall mean the right given under this Warrant
                -------                                               
Certificate to purchase one share of the Company's voting common stock.

          (c)  "Warrant Shares" shall mean the shares of the Company's voting
                --------------                                               
common stock purchased upon exercise of Warrants or which the holder hereof has
the right to purchase upon exercise of Warrants.

     2.   Exercise of Warrants.
          -------------------- 

          (a)  Warrants may be exercised in whole or in part by the surrender of
this Warrant Certificate, properly endorsed, accompanied by written notice to
the Company by execution of the form of subscription attached hereto, at the
principal executive office of the Company and upon payment to the Company by
certified check or bank draft of the Purchase Price for the shares purchasable
thereunder.  The persons entitled to the shares so purchased shall be treated
for all purposes as the holders of such shares as of the close of business on
the date of exercise.  Certificates for the Warrant Shares so purchased together
with a new Warrant Certificate or Certificates of like tenor representing in the
aggregate the right to purchase the number of shares of the Company's common
stock with respect to which Warrants have not been exercised (each such Warrant
Certificate or Certificates to be for such portion of the total shares as the
holder thereof shall designate), shall be issued and delivered to the persons so
entitled within a reasonable time, not exceeding 15 days, after such exercise.

          (b)  Until such time as a Warrant is exercised in whole or in part,
the holder thereof shall have no rights as a shareholder of the Company except
for such rights as are expressly set forth herein.

     3.   Exchange.  This Warrant Certificate is exchangeable, upon the
          --------                                                     
surrender thereof by the holder thereof at any office of the Company, for a new
Warrant Certificate of like tenor representing in the aggregate the right to
purchase the number of shares of the Company's voting common stock purchasable
under the Warrant Certificate being exchanged, each such new Warrant Certificate
to represent the right to subscribe for and purchase such portion of the
aggregate number of shares of the Company's voting common stock represented by
the Warrant Certificate being exchanged as shall be designated by such holder at
the time of such surrender.

     4.   Transfer.
          -------- 

          (a)  This Warrant Certificate and the Warrants are transferable, in
whole or in part, at the principal executive offices of the Company by the
Holder hereof in person or by duly authorized attorney, upon presentation of
this Warrant Certificate properly endorsed for transfer; provided, however that
                                                         --------  -------     
this Warrant Certificate and the Warrants are only so transferable to a legal
successor of Progress or a corporate affiliate of Progress or Progress Bank.

          (b)  Progress acknowledges by acceptance of this Warrant Certificate
that the Warrant Shares may be sold only if the Warrant Shares are registered
under federal and state securities laws or if an exemption from registration is
available.  The Warrant Shares presently 

                                       2
<PAGE>
 
are not so registered, and the Company is under no obligation at any time to
register them under federal or state securities laws, except as expressly
provided in this Warrant Certificate. Each certificate representing Warrant
Shares shall bear a legend substantially the same as the legend set forth on the
first page of this Warrant Certificate.

     5.   Certain Covenants of the Company.  The Company covenants and agrees
          --------------------------------                                   
that all Warrant Shares will, upon issuance, be duly and validly issued, fully
paid and nonassessable, and free from all taxes, liens, and charges with respect
to the issuance thereof provided that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any certificate in a name other than Progress; and, if any other
outstanding shares of Common Stock are then listed on a national or regional
securities exchange, will be so listed.  The Common Stock is not presently
listed on any securities exchange and the Company is under no obligation to list
it.  The Company further covenants and agrees that during the period within
which the rights represented by this Warrant Certificate may be exercised, the
Company shall, at all times, have authorized and reserved for the purpose of
issuance upon exercise of the purchase rights evidenced by this Warrant
Certificate, a sufficient number of shares of the Company's common stock to
provide for the then exercise of the rights represented by this Warrant
Certificate.

     6.   Adjustment of Purchase Price and Number of Shares.  The number of
          -------------------------------------------------                
Warrant Shares purchasable hereunder and the Purchase Price shall be subject to
adjustment from time to time upon the happening of certain events as follows:

          (a)  Reclassification, Consolidation or Merger.  In case of any
               -----------------------------------------                 
reclassification (other than a change in par value or from par value to no par
value) or change of outstanding securities issuable upon exercise of this
Warrant Certificate, or in case of any consolidation or merger of the Company
with or into another corporation (other than a merger with another corporation
in which the Company is a continuing corporation and which does not result in
any such reclassification or change), the Company, or such successor or
purchasing corporation, as the case may be, shall, without payment of any
additional consideration therefor, execute and deliver to each holder of
Warrants, a new Warrant Certificate, providing that the holder of such new
Warrant Certificate shall have the right to exercise such new Warrant
Certificate (upon terms no less favorable to the holder than those then
applicable to this Warrant Certificate) and procure upon such exercise in lieu
of each share of the Company's voting common stock theretofore issuable upon
exercise of the Warrants the kind and amount of shares of stock, other
securities, money or property (the "Consideration") receivable upon such
reclassification, change, consolidation, or merger, by the holder of one share
of the Company's voting common stock issuable upon exercise of the Warrants as
though this Warrant Certificate had been exercised immediately prior to such
reclassification, change, consolidation or merger.  Such new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 6. The provisions of
this Section 6(a) shall similarly apply to successive reclassifications,
changes, consolidations or mergers.  The Company shall use its best efforts to
give Progress no less than 30 days prior written notice of any reclassification,
change of outstanding securities, merger or consolidation described in this
Section 6(a).

                                       3
<PAGE>
 
          (b)  Subdivision or Combination of Shares. If the Company, at any time
               ------------------------------------    
while any Warrants remain outstanding and unexpired, shall subdivide or combine
any of its Common Stock, the Purchase Price shall be proportionately reduced and
the number of Warrant Shares purchasable hereunder proportionately increased, in
the case of a subdivision of shares, or vice versa in the case of a combination
of shares, in either case as of the effective date of such subdivision or
combination.

          (c)  Certain Dividends and Distributions.  If at any time while any
               -----------------------------------                           
Warrants are outstanding and unexpired the Company shall:

          (i)  Pay a dividend payable in its Common Stock, or in rights to
acquire (by exercise, conversion or otherwise) its Common Stock, (in each case
other than where shares are being issued in lieu of cash), then the number of
Warrants shall be adjusted as of the date of such dividend, by multiplying the
number of Warrants represented by this Warrant Certificate immediately prior to
such date by a fraction (I) the numerator of which shall be the total number of
shares of Common Stock outstanding immediately after such dividend and (II) the
denominator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend; or

          (ii) Authorize a distribution of its assets to the holders of its
Common Stock as a dividend in liquidation or by way of return of capital or
other than as a dividend payable out of earnings or surplus legally available
for dividends under applicable law, the Company shall give notice thereof to the
holder of this Warrant Certificate at least 30 days prior to the record date for
determining entitlement to such distribution; and the holder of this Warrant
Certificate shall, upon exercise of the Warrants, be entitled to participate in
such distribution, without payment of any additional consideration therefor,
according to the number of shares of Common Stock held by such holder after the
exercise of the Warrants pro rata with all other holders of the Company's Common
Stock.

          (d)  Adjustment of Purchase Price.  Upon each adjustment of the number
               ----------------------------                                     
of shares of the Company's voting common stock purchasable hereunder, the
Purchase Price then in effect shall likewise be adjusted to that amount
determined by multiplying the Purchase Price then in effect by a fraction the
number of which is the number of shares of the Company's voting common stock
purchasable hereunder immediately prior to the adjustment and the denominator of
which is the number of shares of the Company's voting common stock purchasable
hereunder immediately after such adjustment.

          (e)  Other Action Affecting Common Stock.  If any event occurs as to
               -----------------------------------                            
which the other provisions of this Section 6 are not strictly applicable, or if
strictly applicable would not fairly protect the holder of Warrants against
dilution in accordance with the intent and principles of such Section 6, then
the Board of Directors shall make an adjustment in the application of such
provisions, in accordance with such intent and principles, so as to protect such
anti-dilution rights as aforesaid.

     7.   Notice of Adjustments.  In the event the Company shall take any action
          ---------------------                                                 
which pursuant to Section 6 results in an adjustment of the Purchase Price
and/or the number of Warrant Shares purchasable upon exercise of Warrants, the
Company will give to each holder of 

                                       4
<PAGE>
 
Warrants written notice of such action promptly following its effective date.
Such notice shall contain the Company's certificate signed by its President
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated
(including a description of the basis on which the Company's Board of Directors
made any determination hereunder), and the Purchase Price and number of Warrant
Shares purchasable after giving effect to such adjustment. Failure to give any
notice required by this Warrant Certificate shall not effect the validity of any
action taken that triggers an adjustment under Section 6.

     8.   Participation Rights.  Other than in connection with a public
          --------------------                                         
offering, if an unaffiliated third party makes an offer to the holders of more
than 50% of the outstanding shares of Common Stock of the Company (the "Offer")
to acquire, whether by purchase (including a merger or consolidation), tender or
exchange, in excess of 50% of the outstanding shares of Common Stock of the
Company on a fully diluted basis, which Offer such holders desire to accept, the
Company agrees to promptly forward a copy of the Offer to Progress.  In such
event, the Company agrees not to effect any consolidation or merger to which it
would be a party and to use its best efforts to cause any such other transaction
with the shareholders not to be consummated, unless Progress shall have had a
period of at least ten days from the date it received a copy of the Offer to
exercise this Warrant and participate in the transaction to the same extent, on
a pro rata basis, with the other shareholders of the Company.  Progress
acknowledges that the rights granted hereunder have also been granted to other
security holders of the Company and understands that such rights may be junior
or pari passu with the rights of such other parties.

     9.   No Registration under Securities Act.  Neither this Warrant
          ------------------------------------                       
Certificate nor the Warrant Shares have been registered under the Securities Act
of 1933, as amended (the "Act") or under the securities laws of any state.  In
issuing this Warrant Certificate, the Company has relied upon the exemption from
registration provided by Section 4(2) of the Act for transactions by an issuer
not involving any public offering.  The holder of this Warrant Certificate
acknowledges by acceptance of this Warrant Certificate that the sale of
Warrants, or of any of the Warrant Shares, under certain circumstances may be
deemed to constitute a distribution within the meaning of, and require
registration under, the Act.

     10.  Subsequent Registration by Company of the Securities.
          ---------------------------------------------------- 

          (a)  As used herein, the term "Registrable Security" means each of the
shares of Common Stock issuable upon exercise of this Warrant and any shares of
Common Stock issued upon any stock split or stock dividend in respect of such
shares; provided, however, that Registerable Security shall not include any such
        --------  -------                                                       
shares (i) disposed of pursuant to one or more registration statements under the
Act, (ii) which are saleable pursuant to Rule 144 under the Act or (iii) which
have otherwise been sold or transferred without registration under the Act.

          (b)  If the Company shall seek to register under the Act or qualify
any of its Common Stock (except in connection with or an acquisition, merger or
exchange of stock, to be registered on Forms S-4, S-8 or any successor forms
under the Act) and if the form of registration statement proposed to be used
otherwise may be used for the registration of the Registerable Securities, then,
on each such occasion, the Company shall furnish the holders of 

                                       5
<PAGE>
 
Registerable Securities (including the holders of Warrants exercisable for
Registrable Securities) with at least 30 days prior written notice thereof. At
the written request of any such holders, given within 20 days after the receipt
of such notice, and subject to the provisions of the Registration Rights
Agreement dated April 30, 1998 between the Company and several holders of its
securities (the "Registration Rights Agreement"), the Company will use its best
efforts to cause all of the Registerable Securities for which registration shall
have been so requested to be included in such registration statement. In the
event that the proposed registration by the Company is, in whole or in part, an
underwritten public offering, and the managing underwriter determines and
advises in writing that the securities requested to be included in such
registration exceeds the number which can be sold in such offering, the Company
will include in such registration, in the following order of priority: (i)
first, the securities the Company proposes to register (which triggers this
Section 10), whether for its own account or for the account of any of its
securityholders who have Registrable Securities under and as defined in the
Registration Rights Agreement; (ii) second, the Registrable Securities and the
securities of any other securityholders of the Company (including, but not
limited to, NEPA Venture Fund II, L.P. to the extent it exercises its piggyback
registration rights) with rights equal to those of the holders of Registrable
Securities, pro rata (based on the number of fully diluted shares of the Company
then owned by such holders), and (iii) third, other securities requested to be
included in such registration statement.

          (c)  All expenses in connection with the preparation and filing of any
registration statement under this Section 10, any registration or qualification
under securities or blue Sky laws of states in which the offering will be made
under such registration statement, and any filing fee of the National
Association of Securities Dealers, Inc. relating to such offering, shall be
borne in full by the Company, except for (i) any underwriter's or broker's
commissions applicable to the shares to be sold by the holders of Registerable
Securities, (ii) fees required to be paid by a selling shareholder rather than
the Company in order to comply with Blue Sky or state securities laws, (iii) all
fees or expenses expressly applicable to securities being sold by the holders of
Registrable Securities and (iv) fees or expenses of such holder's counsel.

          (d)  The Company shall indemnify and hold harmless selling holders of
Registrable Securities and, to the extent required in any agreement with any
underwriter or broker-dealer for whom the Registerable Securities may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Act) against all
losses, claims, damages, liabilities, expenses or actions in respect thereof
caused by any untrue statement of a material fact contained in any registration
statement under which such Registerable Securities were registered under the
Act, any preliminary or final prospectus contained therein, or any amendment or
supplement thereto (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registerable
Securities that are subject to a claimed right of indemnification) or caused by
any omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading (unless cured by an
amendment or supplement to the prospectus delivered to the selling holders prior
to the sales of the registerable securities that are subject to a claimed right
or indemnification); except insofar as such losses, claims, damages, liabilities
or expenses are caused by any untrue statement or omission contained in
information furnished in writing to the Company by the selling holders of
Registrable Securities expressly for use therein.  In connection with any such
registration statement, the selling holders of Registrable 

                                       6
<PAGE>
 
Securities will furnish the Company in writing such information as the Company
may reasonably request for use in any such registration statement or prospectus
and they will, as a condition precedent to the Company's obligation hereunder,
agree to indemnify the Company, its directors and officers, and, to the extent
required in any agreement with any underwriter or broker-dealer, each such
underwriter or broker-dealer and each person, if any, who controls the Company
or any underwriter or broker-dealer (within the meaning of the Act) against any
loses, claims, damages, liabilities, statement of a material fact contained in
any such registration statement or prospectus or caused by any omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein no misleading, insofar as such losses, claims, damages,
liabilities, expenses or actions are caused by any untrue statement or omission
based upon information furnished in writing to the Company by the selling
holders expressly for use therein.

          (e)  If a public offering is not completed within nine months after
the effective date of any registration statement filed by the Company pursuant
to Section 10(b), the Company reserves the right, in its option, to withdraw
from registration any securities offered by the Company which have not been sold
during such period.

          (f)  Notwithstanding the foregoing, the Company reserves the right to
delay such registration, or to withhold efforts to cause the registration
statement to become effective, if the Company determines in good faith that such
registration might (i) interfere with or affect the negotiation or completion of
any transaction that is being contemplated by the Company, or (ii) involve
initial or continuing disclosure obligations that might not be in the best
interest of the Company's shareholders.  The selling holders of Registrable
Securities, upon receipt of notice from the Company that an event has occurred
which requires a post-effective amendment to any registration statement or
supplement to the prospectus included therein, shall promptly discontinue the
sale of their Registerable Securities until they receive a copy of a
supplemented or amended prospectus from the Company, which the Company shall
provide as soon as practicable after such notice.

          (g)  The Company shall have the right to grant any registration rights
or register any securities for the account of any person other than holders of
Registerable Securities regardless of whether such rights are senior,
subordinate or equal to those of the holders of Registerable Securities.

          (h)  In the case of any registration initiated under this Section 10,
the Company shall have the right to designate the managing underwriter in any
underwritten offering.  The Company will supply the selling holders of
Registrable Securities with copies of such registration statements and of the
prospectus included therein in such quantities as may be reasonably necessary
for the purpose of the proposed disposition.

     11.  Sale of Warrant Shares Without Registration.  The holder of this
          -------------------------------------------                     
Warrant Certificate, by acceptance hereof, and the holder of any Warrant Shares,
by acceptance thereof, agrees to give written notice to Company of such holder's
intention before selling or otherwise disposing of the Warrant Shares, except to
the extent that such sale is pursuant to a then effective registration
statement.  Such notice shall describe briefly the manner of any proposed sale
or other disposition to be made of Warrant Shares.  Such notice shall be
accompanied by an opinion 

                                       7
<PAGE>
 
of counsel reasonably satisfactory to the Company stating that the proposed
exercise or sale or other disposition may be effected without registration or
qualification (under any federal or state law) of Warrant Shares. The Company,
as promptly as practicable, shall notify such holder if such opinion is
satisfactory, whereupon such holder shall be entitled to sell or otherwise
dispose of the Warrant Shares or to receive the certificates representing the
shares of Common Stock or to receive the certificates representing the Warrant
Shares and dispose of the shares so received, all in accordance with the terms
of the notice of intent delivered by such holder to the Company and in
accordance with all other applicable terms and conditions contained herein.

     12.  Loss, Theft, Destruction or Mutilation.  Upon receipt by the Company
          --------------------------------------                              
of reasonable evidence satisfactory to it of the ownership of and the loss,
theft, destruction or mutilation of a Warrant Certificate and (in the case of
loss, theft, or destruction) of reasonable indemnity and (in the case of
mutilation) upon surrender and cancellation thereof, the Company will execute
and deliver, in lieu thereof, a new Warrant Certificate of like tenor.

in whole or in part at any time or times until seven (7) years after the date

          -----------                                            

          (a) "Common Stock" shall mean, in addition to the classes of common
               ------------

          (b) "Warrant" shall mean the right given under this Warrant
               -------

common stock purchased upon exercise of Warrants or which the holder hereof has
the right to purchase upon exercise of Warrants.

     2.   Exercise of Warrants.
          -------------------- 

          (a) Warrants may be exercised in whole or in part by the surrender of
this Warrant Certificate, properly endorsed, accompanied by written notice to
the Company by execution of the form of subscription attached hereto, at the
principal executive office of the Company and upon payment to the Company by
certified check or bank draft of the Purchase Price for the shares purchasable
thereunder.  The persons entitled to the shares so purchased shall be treated
for all purposes as the holders of such shares as of the close of business on
the date of exercise.  Certificates for the Warrant Shares so purchased together
with a new Warrant Certificate or Certificates of like tenor representing in the
aggregate the right to purchase the number of shares of the Company's common
stock with respect to which Warrants have not been exercised (each such Warrant
Certificate or Certificates to be for such portion of the total shares as the
holder thereof shall designate), shall be issued and delivered to the persons so
entitled within a reasonable time, not exceeding 15 days, after such exercise.

          (b) Until such time as a Warrant is exercised in whole or in part, the
holder thereof shall have no rights as a shareholder of the Company except for
such rights as are expressly set forth herein.

     3.   Exchange.  This Warrant Certificate is exchangeable, upon the
          --------                                                     
surrender thereof by the holder thereof at any office of the Company, for a new
Warrant Certificate of like tenor representing in the aggregate the right to
purchase the number of shares of the Company's voting common stock purchasable
under the Warrant Certificate being exchanged, each such new warrant Certificate
to represent the right to subscribe for and purchase such portion of the
aggregate number of shares of the Company's voting common stock represented by
the Warrant Certificate being exchanged as shall be designated by such holder at
the time of such surrender.

     4.   Transfer.
          -------- 

          (a) This Warrant Certificate and the Warrants are not transferable
except to a legal successor of Meridian Bank.

          (b) Meridian Bank acknowledges by acceptance of this Warrant
Certificate that the Warrant Shares may be sold only if the Warrant Shares are
registered under federal and state securities laws or if an exemption from
registration is available.  The Warrant Shares presently are not so registered,
and the Company is under no obligation at any time to register them under
federal or state securities laws, except as expressly provided in this Warrant

                                       2
<PAGE>
 
Certificate.  Each certificate representing Warrant Shares shall bear a legend
substantially the same as the legend set forth on the first page of this Warrant
Certificate.

     5.   Certain Covenants of the Company.  The Company covenants and agrees
          --------------------------------                                   
that all Warrant Shares will, upon issuance, be duly and validly issued, fully
paid and nonassessable, and free from all taxes, liens, and charges with respect
to the issuance thereof provided that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any certificate in a name other than Meridian Bank; and, if any
other outstanding shares of Common Stock are then listed on a national or
regional securities exchange, will be so listed.  The Common Stock is not
presently listed on any securities exchange and the Company is under no
obligation to list it.  The Company further covenants and agrees that during the
period within which the rights represented by this Warrant Certificate may be
exercised, the Company shall, at all times, have authorized and reserved for the
purpose of issuance upon exercise of the purchase rights evidenced by this
Warrant Certificate, a sufficient number of shares of the Company's common stock
to provide for the then exercise of the rights represented by this warrant
Certificate.

     6.   Adjustment of Purchase Price and Number of Shares.  The number of
          -------------------------------------------------                
Warrant Shares purchasable hereunder and the Purchase Price shall be subject to
adjustment from time to time upon the happening of certain events as follows:

          (a) Reclassification, Consolidation or Merger.  In case of any
              -----------------------------------------                 
reclassification (other than a change in par value or from par value to no par
value) or change of outstanding securities issuable upon exercise of this
Warrant Certificate, or in case of any consolidation or merger of the Company
with or into another corporation (other than a merger with another corporation
in which the Company is a continuing corporation and which does not result in
any such reclassification or change), the Company, or such successor or
purchasing corporation, as the case may be, shall, without payment of any
additional consideration therefor, execute and deliver to each holder of
Warrants, a new Warrant Certificate, providing that the holder of such new
Warrant Certificate shall have the right to exercise such new Warrant
Certificate (upon terms no less favorable to the holder than those then
applicable to this Warrant Certificate) and procure upon such exercise in lieu
of each share of the Company's voting common stock theretofore issuable upon
exercise of the Warrants the kind and amount of shares of stock, other
securities, money or property (the "Consideration") receivable upon such
reclassification, change, consolidation, or merger, by the holder of one share
of the Company's voting common stock issuable upon exercise of the Warrants as
though this Warrant Certificate had been exercised immediately prior to such
reclassification, change, consolidation or merger.  Such new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 6. The provisions of
this Section 6(a) shall similarly apply to successive reclassifications,
changes, consolidations or mergers.  The Company shall use its best efforts to
give Meridian Bank no less than 30 days prior written notice of any
reclassification, change of outstanding securities, merger or consolidation
described in this Section 6(a).

          (b) Subdivision or Combination of Shares.  If the Company, at any time
              ------------------------------------                              
while any Warrants remain outstanding and unexpired, shall subdivide or combine
any of its Common Stock, the Purchase Price shall be proportionately reduced and
the number of Warrant Shares 

                                       3
<PAGE>
 
purchasable hereunder proportionately increased, in the case of a subdivision of
shares, or vice versa in the case of a combination of shares, in either case as
of the effective date of such subdivision or combination.

          (c) Certain Dividends and Distributions.  If at any time while any
              -----------------------------------                           
Warrants are outstanding and unexpired the Company shall:

              (i)  Pay a dividend payable in its Common Stock, or in rights to
acquire (by exercise, conversion or otherwise) its Common Stock, then the number
of Warrants shall be adjusted as of the date of such dividend, by multiplying
the number of Warrants represented by this Warrant Certificate immediately prior
to such date by a fraction (I) the numerator of which shall be the total number
of shares of Common Stock outstanding immediately after such dividend and (II)
the denominator of which shall be the total number of shares of Common Stock
outstanding immediately prior to such dividend; or

              (ii) Authorize a distribution of its assets to the holders of its
Common Stock as a dividend in liquidation or by way of return of capital or
other than as a dividend payable out of earnings or surplus legally available
for dividends under applicable law, the Company shall give notice thereof to the
holder of this Warrant Certificate at least 30 days prior to the record date for
determining entitlement to such distribution; and the holder of this Warrant
Certificate shall, upon exercise of the Warrants, be entitled to participate in
such distribution, without payment of any additional consideration therefor,
according to the number of shares of Common Stock held by such holder after the
exercise of the Warrants pro rata with all other holders of the Company's Common
Stock.

          (d) Adjustment of Purchase Price.  Upon each adjustment of the number
              ----------------------------                                     
of shares of the Company's voting common stock purchasable hereunder, the
Purchase Price then in effect shall likewise be adjusted to that amount
determined by multiplying the Purchase Price then in effect by a fraction the
number of which is the number of shares of the Company's voting common stock
purchasable hereunder immediately prior to the adjustment and the denominator of
which is the number of shares of the Company's voting common stock purchasable
hereunder immediately after such adjustment.

          (e) Other Action Affecting Common Stock.  If any event occurs as to
              -----------------------------------                            
which the other provisions of this Section 6 are not strictly applicable, or if
strictly applicable would not fairly protect the holder of Warrants against
dilution in accordance with the intent and principles of such Section 6, then
the Board of Directors shall make an adjustment in the application of such
provisions, in accordance with such intent and principles, so as to protect such
anti-dilution rights as aforesaid.

     7.   Notice of Adjustments.  In the event the Company shall take any action
          ---------------------                                                 
which pursuant to Section 6 results in an adjustment of the Purchase Price
and/or the number of Warrant Shares purchasable upon exercise of Warrants, the
Company will give to each holder of Warrants written notice of such action
promptly following its effective date.  Such notice shall contain the Company's
certificate signed by its President setting forth, in reasonable detail, the
event requiring the adjustment, the amount of the adjustment, the method by
which such adjustment was calculated (including a description of the basis on
which the Company's Board of 

                                       4
<PAGE>
 
Directors made any determination hereunder), and the Purchase Price and number
of Warrant Shares purchasable after giving effect to such adjustment. Failure to
give any notice required by this Warrant Certificate shall not effect the
validity of any action taken that triggers an adjustment under Section 6.

     8.   Co-Sale Rights.  Until an initial public offering of securities of the
          --------------                                                        
Company, in the event Gregg Garnick (the "Principal") receives a bona fide
offer, which offer the Principal desires to accept, from an unaffiliated third
party (hereinafter called the "Section 8 Offeror") to purchase more than 50% of
the Common Stock of the Company owned by the Principal for a specified price
Payable in cash or otherwise and on specified terms and conditions (hereinafter
called the "Section 8 Offer"), the Principal shall promptly forward a copy of
the Section 8 Offer to Meridian Bank.  The Principal shall not transfer any such
securities to the Section 8 Offeror unless the Section 8 Offeror offers to
concurrently purchase a pro rata number of Warrant Shares which Meridian Bank,
by written notice to the Principal given within 10 days after their receipt of
the Section 8 Offer, advises it wants to sell on the terms and conditions set
forth in the Section 8 Offer.  If Meridian Bank has not yet exercised the
Warrants covering the Warrant Shares it wishes to sell, it must do so prior to
the closing of such sale.  For purposes of determining Meridian Bank's "pro rata
number of Warrant Shares", Meridian Bank shall be deemed to hold all Warrant
Shares actually then held by it plus all Warrant Shares issuable under upon
exercise of the Warrants then held by it.  Meridian Bank acknowledges that the
rights granted hereunder have also been granted to other security holders of the
Company and agrees that such rights shall be pari passu with the rights of such
other parties.

     9.   No Registration under Securities Act.  Neither this Warrant
          ------------------------------------                       
Certificate nor the Warrant Shares have been registered under the Securities Act
of 1933, as amended (the "Act") or under the securities laws of any state.  In
issuing this Warrant Certificate, the Company has relied upon the exemption from
registration provided by Section 4(2) of the Act for transactions by an issuer
not involving any public offering.  The holder of this Warrant Certificate
acknowledges by acceptance of this Warrant Certificate that the sale of
Warrants, or of any of the Warrant Shares, under certain circumstances may be
deemed to constitute a distribution within the meaning of, and require
registration under, the Act.

     10.  Subsequent Registration by Company of the Securities.
          ---------------------------------------------------- 

          (a) As used herein, the term "Registrable Security" means each of the
shares of Common Stock issuable upon exercise of this Warrant and any shares of
Common Stock issued upon any stock split or stock dividend in respect of such
shares; provided, however, that Registerable Security shall not include any such
        --------  -------                                                       
shares (i) disposed of pursuant to one or more registration statements under the
Act, (ii) which are saleable pursuant to Rule 144 under the Act or (iii) which
have otherwise been sold or transferred without registration under the Act.

          (b) If the Company shall seek to register under the Act or qualify any
of its Common Stock (except in connection with or an acquisition, merger or
exchange of stock, to be registered on Forms S-4, S-8 or any successor forms
under the Act) and if the form of registration statement proposed to be used
otherwise may be used for the registration of the Registerable Securities, then,
on each such occasion, the Company shall furnish the holders of Registerable
Securities (including the holders of Warrants exercisable for Registrable
Securities) 

                                       5
<PAGE>
 
with at least 30 days prior written notice thereof. At the written request of
any such holders, given within 20 days after the receipt of such notice, the
Company will use its best efforts to cause all of the Registerable Securities
for which registration shall have been so requested to be included in such
registration statement. In the event that the proposed registration by the
Company is, in whole or in part, an underwritten public offering, and the
managing underwriter determines and advises in writing that the securities
requested to be included in such registration exceeds the number which can be
sold in such offering, the Company will include in such registration, in the
following order of priority: (i) first, the securities the Company proposes to
register (which triggers this Section 10), whether for its own account or for
the account of any of its securityholders who have exercised demand registration
rights or who hold shares of Common Stock representing not less than five
percent (5%) of the issued and outstanding Common Stock of the Company on a
fully-diluted basis; (ii) second, the Registrable Securities and the securities
of any other securityholders of the Company (including, but not limited to, NEPA
Venture Fund II, L.P. to the extent it exercises its piggyback registration
rights) with rights equal to those of the holders of Registrable Securities, pro
rata (based on the number of fully diluted shares of the Company then owned by
such holders), and (iii) third, other securities requested to be included in
such registration statement.

          (c) All expenses in connection with the preparation and filing of any
registration statement under this Section 10, any registration or qualification
under securities or blue Sky laws of states in which the offering will be made
under such registration statement, and any filing fee of the National
Association of Securities Dealers, Inc. relating to such offering, shall be
borne in full by the Company, except for (i) any underwriter's or broker's
commissions applicable to the shares to be sold by the holders of Registerable
Securities, (ii) fees required to be paid by a selling shareholder rather than
the Company in order to comply with Blue Sky or state securities laws, (iii) all
fees or expenses expressly applicable to securities being sold by the holders of
Registrable Securities and (iv) fees or expenses of such holder's counsel.

          (d) The Company shall indemnify and hold harmless selling holders of
Registrable Securities and, to the extent required in any agreement with any
underwriter or broker-dealer for whom the Registerable Securities may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Act) against all
losses, claims, damages, liabilities, expenses or actions in respect thereof
caused by any untrue statement of a material fact contained in any registration
statement under which such Registerable Securities were registered under the
Act, any preliminary or final prospectus contained therein, or any amendment or
supplement thereto (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registerable
Securities that are subject to a claimed right of indemnification) or caused by
any omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading (unless cured by an
amendment or supplement to the prospectus delivered to the selling holders prior
to the sales of the registerable securities that are subject to a claimed right
or indemnification); except insofar as such losses, claims, damages, liabilities
or expenses are caused by any untrue statement or omission contained in
information furnished in writing to the Company by the selling holders of
Registrable Securities expressly for use therein.  In connection with any such
registration statement, the selling holders of Registrable Securities will
furnish the Company in writing such information as the Company may reasonably
request for use in any such registration statement or prospectus and they will,
as a condition 

                                       6
<PAGE>
 
precedent to the Company's obligation hereunder, agree to indemnify the Company,
its directors and officers, and, to the extent required in any agreement with
any underwriter or broker-dealer, each such underwriter or broker-dealer and
each person, if any, who controls the Company or any underwriter or broker-
dealer (within the meaning of the Act) against any loses, claims, damages,
liabilities, statement of a material fact contained in any such registration
statement or prospectus or caused by any omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
no misleading, insofar as such losses, claims, damages, liabilities, expenses or
actions are caused by any untrue statement or omission based upon information
furnished in writing to the Company by the selling holders expressly for use
therein.

          (e) If a public offering is not completed within nine months after the
effective date of any registration statement filed by the Company pursuant to
Section 10(b), the Company reserves the right, in its option, to withdraw from
registration any securities offered by the Company which have not been sold
during such period.

          (f) Notwithstanding the foregoing, the Company reserves the right to
delay such registration, or to withhold efforts to cause the registration
statement to become effective, if the Company determines in good faith that such
registration might (i) interfere with or affect the negotiation or completion of
any transaction that is being contemplated by the Company, or (ii) involve
initial or continuing disclosure obligations that might not be in the best
interest of the Company's shareholders.

The selling holders of Registrable Securities, upon receipt of notice from the
Company that an event has occurred which requires a post-effective amendment to
any registration statement or supplement to the prospectus included therein,
shall promptly discontinue the sale of their Registerable Securities until they
receive a copy of a supplemented or amended prospectus from the Company, which
the Company shall provide as soon as practicable after such notice.

          (g) The Company shall have the right to grant any registration rights
or register any securities for the account of any person other than holders of
Registerable Securities regardless of whether such rights are senior,
subordinate or equal to those of the holders of Registerable Securities.

          (h) In the case of any registration initiated under this Section 10,
the Company shall have the right to designate the managing underwriter in any
underwritten offering.  The Company will supply the selling holders of
Registrable Securities with copies of such registration statements and of the
prospectus included therein in such quantities as may be reasonably necessary
for the purpose of the proposed disposition.

     11.  Sale of Warrant Shares Without Registration.  The holder of this
          -------------------------------------------                     
Warrant Certificate, by acceptance hereof, and the holder of any Warrant Shares,
by acceptance thereof, agrees to give written notice to Company of such holder's
intention before selling or otherwise disposing of the Warrant Shares, except to
the extent that such sale is pursuant to a then effective registration
statement.  Such notice shall describe briefly the manner of any proposed sale
or other disposition to be made of Warrant Shares.  Such notice shall be
accompanied by an opinion of counsel reasonably satisfactory to the Company
stating that the proposed exercise or sale or 

                                       7
<PAGE>
 
other disposition may be effected without registration or qualification (under
any federal or state law) of Warrant Shares. The Company, as promptly as
practicable, shall notify such holder if such opinion is satisfactory, whereupon
such holder shall be entitled to sell or otherwise dispose of the Warrant Shares
or to receive the certificates representing the shares of Common Stock or to
receive the certificates representing the Warrant Shares and dispose of the
shares so received, all in accordance with the terms of the notice of intent
delivered by such holder to the Company and in accordance with all other
applicable terms and conditions contained herein.

     12.  Loss, Theft, Destruction or Mutilation.  Upon receipt by the Company
          --------------------------------------                              
of reasonable evidence satisfactory to it of the ownership of and the loss,
theft, destruction or mutilation of a Warrant Certificate and (in the case of
loss, theft, or destruction) of reasonable indemnity and (in the case of
mutilation) upon surrender and cancellation thereof, the Company will execute
and deliver, in lieu thereof, a new Warrant Certificate of like tenor.

     13.  Notices.  All notices, requests and demands to or upon the Company
          -------

thousand (100,000) fully paid and non-assessable shares of the Company's voting

giving effect to the stock split in the form of a 19 for 1 stock dividend to
occur in March, 1996 (the "1996 Stock Dividend").  The holder of this Warrant
Certificate shall have the right to exercise the rights provided for herein
(such rights, with respect to each such share, is called herein a "Warrant" and
with respect to more than one share, is called herein "Warrants"), in whole or
in part at any time or times until seven (7) years after the date hereof (as set

     1.   Definitions.  For purposes of this Warrant Certificate:
          -----------                                            

          (a) "Common Stock" shall mean, in addition to the classes of common
               ------------                                                  
stock now in existence, any and all other stock of any class which has the right
to participate in the 
<PAGE>
 
distribution of earnings and assets of the Company without limit as to amount or
percentage. "Common Stock" shall not include any shares at any time directly or
indirectly owned by the Company.

          (b) "Warrant" shall mean the right given under this Warrant
               -------

common stock purchased upon exercise of Warrants or which the holder hereof has
the right to purchase upon exercise of Warrants.

     2.   Exercise of Warrants.
          -------------------- 

          (a) Warrants may be exercised in whole or in part by the surrender of
this Warrant Certificate, properly endorsed, accompanied by written notice to
the Company by execution of the form of subscription attached hereto, at the
principal executive office of the Company and upon payment to the Company by
certified check or bank draft of the Purchase Price for the shares purchasable
thereunder.  The persons entitled to the shares so purchased shall be treated
for all purposes as the holders of such shares as of the close of business on
the date of exercise.  Certificates for the Warrant Shares so purchased together
with a new Warrant Certificate or Certificates of like tenor representing in the
aggregate the right to purchase the number of shares of the Company's common
stock with respect to which Warrants have not been exercised (each such Warrant
Certificate or Certificates to be for such portion of the total shares as the
holder thereof shall designate), shall be issued and delivered to the persons so
entitled within a reasonable time, not exceeding 15 days, after such exercise.

          (b) Until such time as a Warrant is exercised in whole or in part, the
holder thereof shall have no rights as a shareholder of the Company except for
such rights as are expressly set forth herein.

     3.   Exchange.  This Warrant Certificate is exchangeable, upon the
          --------                                                     
surrender thereof by the holder thereof at any office of the Company, for a new
Warrant Certificate of like tenor representing in the aggregate the right to
purchase the number of shares of the Company's voting common stock purchasable
under the Warrant Certificate being exchanged, each such new Warrant Certificate
to represent the right to subscribe for and purchase such portion of the
aggregate number of shares of the Company's voting common stock represented by
the Warrant Certificate being exchanged as shall be designated by such holder at
the time of such surrender.

     4.   Transfer.
          -------- 

          (a) This Warrant Certificate and the Warrants are not transferable
except to a legal successor of Meridian Bank.

          (b) Meridian Bank acknowledges by acceptance of this Warrant
Certificate that the Warrant Shares may be sold only if the Warrant Shares are
registered under federal and state securities laws or if an exemption from
registration is available.  The Warrant Shares presently are not so registered,
and the Company is under no obligation at any time to register them under
federal or state securities laws, except as expressly provided in this Warrant

                                       2
<PAGE>
 
Certificate.  Each certificate representing Warrant Shares shall bear a legend
substantially the same as the legend set forth on the first page of this Warrant
Certificate.

     5.   Certain Covenants of the Company.  The Company covenants and agrees
          --------------------------------                                   
that all Warrant Shares will, upon issuance, be duly and validly issued, fully
paid and nonassessable, and free from all taxes, liens, and charges with respect
to the issuance thereof provided that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any certificate in a name other than Meridian Bank; and, if any
other outstanding shares of Common Stock are then listed on a national or
regional securities exchange, will be so listed.  The Common Stock is not
presently listed on any securities exchange and the Company is under no
obligation to list it.  The Company further covenants and agrees that during the
period within which the rights represented by this Warrant Certificate may be
exercised, the Company shall, at all times, have authorized and reserved for the
purpose of issuance upon exercise of the purchase rights evidenced by this
Warrant Certificate, a sufficient number of shares of the Company's common stock
to provide for the then exercise of the rights represented by this Warrant
Certificate.

     6.   Adjustment of Purchase Price and Number of Shares.  The number of
          -------------------------------------------------                
Warrant Shares purchasable hereunder and the Purchase Price shall be subject to
adjustment from time to time upon the happening of certain events as follows:

          (a) Reclassification, Consolidation or Merger.  In case of any
              -----------------------------------------                 
reclassification (other than a change in par value or from par value to no par
value) or change of outstanding securities issuable upon exercise of this
Warrant Certificate, or in case of any consolidation or merger of the Company
with or into another corporation (other than a merger with another corporation
in which the Company is a continuing corporation and which does not result in
any such reclassification or change), the Company, or such successor or
purchasing corporation, as the case may be, shall, without payment of any
additional consideration therefor, execute and deliver to each holder of
Warrants, a new Warrant Certificate, providing that the holder of such new
Warrant Certificate shall have the right to exercise such new Warrant
Certificate (upon terms no less favorable to the holder than those then
applicable to this Warrant Certificate) and procure upon such exercise in lieu
of each share of the Company's voting common stock theretofore issuable upon
exercise of the Warrants the kind and amount of shares of stock, other
securities, money or property (the "Consideration") receivable upon such
reclassification, change, consolidation, or merger, by the holder of one share
of the Company's voting common stock issuable upon exercise of the Warrants as
though this Warrant Certificate had been exercised immediately prior to such
reclassification, change, consolidation or merger.  Such new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 6. The provisions of
this Section 6(a) shall similarly apply to successive reclassifications,
changes, consolidations or mergers.  The Company shall use its best efforts to
give Meridian Bank no less than 30 days prior written notice of any
reclassification, change of outstanding securities, merger or consolidation
described in this Section 6(a).

          (b) Subdivision or Combination of Shares.  If the Company, at any time
              ------------------------------------                              
while any Warrants remain outstanding and unexpired, shall subdivide or combine
any of its Common Stock, the Purchase Price shall be proportionately reduced and
the number of Warrant Shares 

                                       3
<PAGE>
 
purchasable hereunder proportionately increased, in the case of a subdivision of
shares, or vice versa in the case of a combination of shares, in either case as
of the effective date of such subdivision or combination.

          (c) Certain Dividends and Distributions.  If at any time while any
              -----------------------------------                           
Warrants are outstanding and unexpired the Company shall:

              (i)  Pay a dividend payable in its Common Stock (other than the
1996 Stock Dividend), or in rights to acquire (by exercise, conversion or
otherwise) its Common Stock, then the number of Warrants shall be adjusted as of
the date of such dividend, by multiplying the number of Warrants represented by
this Warrant Certificate immediately prior to such date by a fraction (I) the
numerator of which shall be the total number of shares of Common Stock
outstanding immediately after such dividend and (II) the denominator of which
shall be the total number of shares of Common Stock outstanding immediately
prior to such dividend; or

              (ii) Authorize a distribution of its assets to the holders of its
Common Stock as a dividend in liquidation or by way of return of capital or
other than as a dividend payable out of earnings or surplus legally available
for dividends under applicable law, the Company shall give notice thereof to the
holder of this Warrant Certificate at least 30 days prior to the record date for
determining entitlement to such distribution; and the holder of this Warrant
Certificate shall, upon exercise of the Warrants, be entitled to participate in
such distribution, without payment of any additional consideration therefor,
according to the number of shares of Common Stock held by such holder after the
exercise of the Warrants pro rata with all other holders of the Company's Common
Stock.

          (d) Adjustment of Purchase Price.  Upon each adjustment of the number
              ----------------------------                                     
of shares of the Company's voting common stock purchasable hereunder, the
Purchase Price then in effect shall likewise be adjusted to that amount
determined by multiplying the Purchase Price then in effect by a fraction the
number of which is the number of shares of the Company's voting common stock
purchasable hereunder immediately prior to the adjustment and the denominator of
which is the number of shares of the Company's voting common stock purchasable
hereunder immediately after such adjustment.

          (e) Other Action Affecting Common Stock.  If any event occurs as to
              -----------------------------------                            
which the other provisions of this Section 6 are not strictly applicable, or if
strictly applicable would not fairly protect the holder of Warrants against
dilution in accordance with the intent and principles of such Section 6, then
the Board of Directors shall make an adjustment in the application of such
provisions, in accordance with such intent and principles, so as to protect such
anti-dilution rights as aforesaid.

     7.   Notice of Adjustments.  In the event the Company shall take any action
          ---------------------                                                 
which pursuant to Section 6 results in an adjustment of the Purchase Price
and/or the number of Warrant Shares purchasable upon exercise of Warrants, the
Company will give to each holder of Warrants written notice of such action
promptly following its effective date.  Such notice shall contain the Company's
certificate signed by its President setting forth, in reasonable detail, the
event requiring the adjustment, the amount of the adjustment, the method by
which such adjustment was calculated (including a description of the basis on
which the Company's Board of 

                                       4
<PAGE>
 
Directors made any determination hereunder), and the Purchase Price and number
of Warrant Shares purchasable after giving effect to such adjustment. Failure to
give any notice required by this Warrant Certificate shall not effect the
validity of any action taken that triggers an adjustment under Section 6.

     8.   Co-Sale Rights.  Until an initial public offering of securities of the
          --------------                                                        
Company, in the event Gregg Garnick (the "Principal") receives a bona fide
offer, which offer the Principal desires to accept, from an unaffiliated third
party (hereinafter called the "Section 8 Offeror") to purchase more than 50% of
the Common Stock of the Company owned by the Principal for a specified price
payable in cash or otherwise and on specified terms and conditions (hereinafter
called the "Section 8 Offer"), the Principal shall promptly forward a copy of
the Section 8 offer to Meridian Bank.  The Principal shall not transfer any such
securities to the Section 8 Offeror unless the Section 8 Offeror offers to
concurrently purchase a pro rata number of Warrant Shares which Meridian Bank,
by written notice to the Principal given within 10 days after their receipt of
the Section 8 Offer, advises it wants to sell on the terms and conditions set
forth in the Section 8 Offer.  If Meridian Bank has not yet exercised the
Warrants covering the Warrant Shares it wishes to sell, it must do so prior to
the closing of such sale.  For purposes of determining Meridian Bank's "pro rata
number of Warrant Shares", Meridian Bank shall be deemed to hold all Warrant
Shares actually then held by it plus all Warrant Shares issuable under upon
exercise of the Warrants then held by it.  Meridian Bank acknowledges that the
rights granted hereunder have also been granted to other security holders of the
Company and agrees that such rights shall be pari passu with the rights of such
other parties.

     9.   No Registration under Securities Act.  Neither this Warrant
          ------------------------------------                       
Certificate nor the Warrant Shares have been registered under the Securities Act
of 1933, as amended (the "Act") or under the securities laws of any state.  In
issuing this Warrant Certificate, the Company has relied upon the exemption from
registration provided by Section 4(2) of the Act for transactions by an issuer
not involving any public offering.  The holder of this Warrant Certificate
acknowledges by acceptance of this Warrant Certificate that the sale of
Warrants, or of any of the Warrant Shares, under certain circumstances may be
deemed to constitute a distribution within the meaning of, and require
registration under, the Act.

     10.  Subsequent Registration by Company of the Securities.
          ---------------------------------------------------- 

          (a) As used herein, the term "Registrable Security" means each of the
shares of Common Stock issuable upon exercise of this Warrant and any shares of
Common Stock issued upon any stock split or stock dividend in respect of such
shares; provided, however, that Registerable Security shall not include any such
        --------  -------                                                       
shares (i) disposed of pursuant to one or more registration statements under the
Act, (ii) which are saleable pursuant to Rule 144 under the Act or (iii) which
have otherwise been sold or transferred without registration under the Act.

          (b) If the Company shall seek to register under the Act or qualify any
of its Common Stock (except in connection with or an acquisition, merger or
exchange of stock, to be registered on Forms S-4, S-8 or any successor forms
under the Act) and if the form of registration statement proposed to be used
otherwise may be used for the registration of the Registerable Securities, then,
on each such occasion, the Company shall furnish the holders of Registerable
Securities (including the holders of Warrants exercisable for Registrable
Securities) 

                                       5
<PAGE>
 
with at least 30 days prior written notice thereof. At the written request of
any such holders, given within 20 days after the receipt of such notice, the
Company will use its best efforts to cause all of the Registerable Securities
for which registration shall have been so requested to be included in such
registration statement. In the event that the proposed registration by the
Company is, in whole or in part, an underwritten public offering, and the
managing underwriter determines and advises in writing that the securities
requested to be included in such registration exceeds the number which can be
sold in such offering, the Company will include in such registration, in the
following order of priority: (i) first, the securities the Company proposes to
register (which triggers this Section 10), whether for its own account or for
the account of any of its securityholders who have exercised demand registration
rights or who hold shares of Common Stock representing not less than five
percent (5%) of the issued and outstanding Common Stock of the Company on a
fully-diluted basis; (ii) second, the Registrable Securities and the securities
of any other securityholders of the Company (including, but not limited to, NEPA
Venture Fund II, L.P. to the extent it exercises its piggyback registration
rights) with rights equal to those of the holders of Registrable Securities, pro
rata (based on the number of fully diluted shares of the Company then owned by
such holders), and (iii) third, other securities requested to be included in
such registration statement.

          (c) All expenses in connection with the preparation and filing of any
registration statement under this Section 10, any registration or qualification
under securities or blue Sky laws of states in which the offering will be made
under such registration statement, and any filing fee of the National
Association of Securities Dealers, Inc. relating to such offering, shall be
borne in full by the Company, except for (i) any underwriter's or broker's
commissions applicable to the shares to be sold by the holders of Registerable
Securities, (ii) fees required to be paid by a selling shareholder rather than
the Company in order to comply with Blue Sky or state securities laws, (iii) all
fees or expenses expressly applicable to securities being sold by the holders of
Registrable Securities and (iv) fees or expenses of such holder's counsel.

          (d) The Company shall indemnify and hold harmless selling holders of
Registrable Securities and, to the extent required in any agreement with any
underwriter or broker-dealer for whom the Registerable Securities may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Act) against all
losses, claims, damages, liabilities, expenses or actions in respect thereof
caused by any untrue statement of a material fact contained in any registration
statement under which such Registerable Securities were registered under the
Act, any preliminary or final prospectus contained therein, or any amendment or
supplement thereto (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registerable
Securities that are subject to a claimed right of indemnification) or caused by
any omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading (unless cured by an
amendment or supplement to the prospectus delivered to the selling holders prior
to the sales of the registerable securities that are subject to a claimed right
or indemnification); except insofar as such losses, claims, damages, liabilities
or expenses are caused by any untrue statement or omission contained in
information furnished in writing to the Company by the selling holders of
Registrable Securities expressly for use therein.  In connection with any such
registration statement, the selling holders of Registrable Securities will
furnish the Company in writing such information as the Company may reasonably
request for use in any such registration statement or prospectus and they will,
as a condition 

                                       6
<PAGE>
 
precedent to the Company's obligation hereunder, agree to indemnify the Company,
its directors and officers, and, to the extent required in any agreement with
any underwriter or broker-dealer, each such underwriter or broker-dealer and
each person, if any, who controls the Company or any underwriter or broker-
dealer (within the meaning of the Act) against any loses, claims, damages,
liabilities, statement of a material fact contained in any such registration
statement or prospectus or caused by any omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
no misleading, insofar as such losses, claims, damages, liabilities, expenses or
actions are caused by any untrue statement or omission based upon information
furnished in writing to the Company by the selling holders expressly for use
therein.

          (e) If a public offering is not completed within nine months after the
effective date of any registration statement filed by the Company pursuant to
Section 10(b), the Company reserves the right, in its option, to withdraw from
registration any securities offered by the Company which have not been sold
during such period.

          (f) Notwithstanding the foregoing, the Company reserves the right to
delay such registration, or to withhold efforts to cause the registration
statement to become effective, if the Company determines in good faith that such
registration might (i) interfere with or affect the negotiation or completion of
any transaction that is being contemplated by the Company, or (ii) involve
initial or continuing disclosure obligations that might not be in the best
interest of the Company's shareholders.  The selling holders of Registrable
Securities, upon receipt of notice from the Company that an event has occurred
which requires a post-effective amendment to any registration statement or
supplement to the prospectus included therein, shall promptly discontinue the
sale of their Registerable Securities until they receive a copy of a
supplemented or amended prospectus from the Company, which the Company shall
provide as soon as practicable after such notice.

          (g) The Company shall have the right to grant any registration rights
or register any securities for the account of any person other than holders of
Registerable Securities regardless of whether such rights are senior,
subordinate or equal to those of the holders of Registerable Securities.

          (h) In the case of any registration initiated under this Section 10,
the Company shall have the right to designate the managing underwriter in any
underwritten offering.  The Company will supply the selling holders of
Registrable Securities with copies of such registration statements and of the
prospectus included therein in such quantities as may be reasonably necessary
for the purpose of the proposed disposition.

     11.  Sale of Warrant Shares Without Registration.  The holder of this
          -------------------------------------------                     
Warrant Certificate, by acceptance hereof, and the holder of any Warrant Shares,
by acceptance thereof, agrees to give written notice to Company of such holder's
intention before selling or otherwise disposing of the Warrant Shares, except to
the extent that such sale is pursuant to a then effective registration
statement.  Such notice shall describe briefly the manner of any proposed sale
or other disposition to be made of Warrant Shares.  Such notice shall be
accompanied by an opinion of counsel reasonably satisfactory to the Company
stating that the proposed exercise or sale or other disposition may be effected
without registration or qualification (under any federal or state 

                                       7
<PAGE>
 
law) of Warrant Shares. The Company, as promptly as practicable, shall notify
such holder if such opinion is satisfactory, whereupon such holder shall be
entitled to sell or otherwise dispose of the Warrant Shares or to receive the
certificates representing the shares of Common Stock or to receive the
certificates representing the Warrant Shares and dispose of the shares so
received, all in accordance with the terms of the notice of intent delivered by
such holder to the Company and in accordance with all other applicable terms and
conditions contained herein.

     12.  Loss, Theft, Destruction or Mutilation.  Upon receipt by the Company
          --------------------------------------                              
of reasonable evidence satisfactory to it of the ownership of and the loss,
theft, destruction or mutilation of a Warrant Certificate and (in the case of
loss, theft, or destruction) of reasonable indemnity and (in the case of
mutilation) upon surrender and cancellation thereof, the Company will execute
and deliver, in lieu thereof, a new Warrant Certificate of like tenor.

     13.  Notices.  All notices, requests and demands to or upon the Company

result thereof, are subject to substantial restrictions on transfer. The

subsequently registered under the Securities Act and any applicable state
securities or Blue Sky laws, or exemptions from registration under the
Securities Act and such laws are available.

Investor and constitutes a valid and legally binding obligation of the Investor,
enforceable in accordance with its terms, subject, as to enforcement, to

its financial statements with those of a subsidiary corporation, the Company
shall thereafter furnish the financial statements required by this Section 6.1
on a consolidated basis, and the quarterly and annual financial statements

Shareholders' Agreement.

               (c)  Amend its Articles of Incorporation (including as amended by
the Amendment) or By-laws.

               (d)  Effect any material change in the nature of the business of
the Company, or apply the assets of the Company other than for the conduct of
the business of the Company, as such business is conducted and proposed to be
conducted.

          7.2  Liens and Encumbrances.  Except for Permitted Liens (as defined
               ----------------------                                         
in Section 3.18), the Company shall not create, assume, or permit to exist any
lien, security interest, pledge or other encumbrance, under conditional or
installment sale arrangements or otherwise, with respect to its properties or
assets, whether tangible or intangible, now owned or hereafter acquired, except

payable in cash or other property or make or authorize any other distribution,

               ----------                                                 
agreement, lease or other instrument which, by its terms, restricts, in any

          7.5  Insider Transactions.  The Company shall not enter into any
               --------------------

by which the Company is bound.

          7.8  Material Contracts.  Other than renewing the Employment
               ------------------                                     
Agreements on their current terms and conditions, the Company shall not, during
any fiscal year of the Company, enter into material contracts pursuant to which

pretax profits for the year in which such bonuses are paid.

          7.10 Acquisitions.  The Company shall not acquire the stock or all or
               ------------

          7.11 Limitations on Raising Additional capital.  The Company, the
               -----------------------------------------

prohibited a transaction to raise capital from either a Non-Private Source or a
Corporate Source, the Company shall be permitted to raise capital from a Non-
Private Source, and the Company shall be permitted to raise equity capital from

     VIII.  Registration and Related Rights.
            ------------------------------- 

            8.1  Piggyback Registration.
                 ---------------------- 

               (a)  As used in this Section 8, "Registration Stock" shall mean:
                                                ------------------
the Conversion Shares (as defined in Section 1.4), and any shares of Common
Stock issued in respect of the Preferred Stock or the Conversion Shares upon any
stock split, stock dividend, recapitalization, merger, consolidation or similar
event; provided, however, that Registration Stock shall not include any such
       --------  -------
shares disposed of pursuant to one or more registration statements under the
Securities Act, or which have been sold pursuant to Rule 144 under the
Securities Act or which have otherwise been sold without registration under the
Securities Act. For purposes of this Section 8, any record holder of securities
convertible into Registration Stock (or exercisable for securities which are
convertible into Registration Stock) shall be deemed to be the holder of the
Registration Stock issuable upon such exercise and/or conversion.

          (b)  If the Company shall seek to register under the Securities Act or
qualify any of the securities holdings of the Company or any of its shareholders
(except in connection with any stock option plan, stock purchase plan, savings
or similar plan or an acquisition, merger or exchange of stock, to be registered
on Forms S-4, S-8 or any successor forms under the Securities Act) and if the
form of registration statement proposed to be used otherwise may be used for the
registration of the Registration Stock (as herein defined), then, on each such
occasion, the Company shall furnish the Investor with at least 30 days prior
written notice thereof.  At the written request of the Investor, given within 20
days after the receipt of such notice, the Company will use its best efforts to
cause all of the Registration Stock for which registration shall have been
requested by the Investor to be included in such registration statement.  In the
event that the proposed registration by the Company is, in whole or in part, an
underwritten public offering of securities of the Company, and the managing
underwriter determines and advises in writing that the inclusion of all
Registration Stock proposed to be included in the underwritten public offering
and other issued and outstanding shares of Common Stock proposed to be included
therein by persons other than (i) holders of Registration Stock or (ii) holders
of Subordinate Stock (as defined in Section 8.4) with rights equal to those of
the holders of Registration Stock ("Other Registration Stock) (such other shares
which are not Registration Stock or Other Registration Stock being the "Other
Shares") would interfere with the successful marketing (including pricing) of
the securities, then the number of shares of 

                                       19
<PAGE>
 
Registration Stock, Other Registration Stock and Other Shares to be included in
such underwritten public offering shall be reduced first, pro rata among the
holders of Other Shares; second, if necessary, pro rata among the holders of
Registration Stock and Other Registration Stock combined, based upon the number
of shares requested by holders thereof to be registered in such underwritten
public offering; and lastly, if necessary, among the Company's shares requested
by the Company to be registered; provided, however, that the holders of
                                 --------  -------
Registration Stock do not then elect to exercise their rights under Section 8.2;
and, further provided, that in no event, without the consent of the holders of
at least 67% of the Registration Stock, the percentage of the Registration Stock
that is included in such registration statement shall not be less than the
percentage of the securities of any other shareholder included therein. In the
event that the Company offers any of its securities in an offering exempt from
registration under the Securities Act pursuant to Regulation A, the Company will
provide to the holders of Registration Stock rights comparable to those provided
herein.

          8.2  Demand Registration.
               ------------------- 

               (a)  If at any time, the Company shall be requested in writing by
the holders of not less than 67% of the Registration Stock to effect the
registration under the Securities Act of at least 33 1/3% of the Registration
Stock, the Company shall promptly give written notice of such proposed
registration to all record holders of Registration Stock. Such holders shall
have the right, by giving written notice to the Company within 30 days from
receipt of the Company's notice, to elect to have included in such registration
such of their Registration Stock as such holders may request in such notice of
election. Thereupon, the Company shall, as expeditiously as possible, use its
best efforts to effect the registration, on a form of general use under the
Securities Act, of all shares of Registration Stock which the Company has been
requested to register; provided, however, that if the holders of not less than
                       --------  -------                                      
67% of the Registration Stock shall so request (and at least 50% of the
Registration Stock is being registered), the Company shall file such
registration statement pursuant to Rule 415 or any successor rule or regulation
under the Securities Act, so as to permit the continuous or delayed offering of
the Registration Stock in accordance with the intended method of disposition
specified in the notice of the exercise of rights under this Section 8.2(a), to
the extent such offering qualifies under such rule or regulation, but in no
event shall the Company be required to maintain the effectiveness of such
registration statement beyond a two year period. The Company shall be obligated
to cause to become effective one registration statement pursuant to which
Registration Stock is sold under this Section 8.2(a).

               (b)  In addition and not in limitation of the rights set forth in
Sections 8.1(b) and 8.2(a), at such time as the Company shall have qualified for
the use of Form S-2 or Form S-3 in an offering solely for the accounts of
persons other than the Company (or any similar form or forms promulgated by the
Securities and Exchange Commission), the holders of not less than 67% of the
Registration Stock shall have the right to request an unlimited number of
registrations on Form S-2 or Form S-3 or other similar forms.  Such holders
shall have the right, by giving written notice to the Company within 20 days
from receipt of the Company's notice, to elect to have included in such
registration such of their Registration Stock as such holders may request in
such notice of election.  Thereupon, the Company shall, as expeditiously as
possible, use its best efforts to effect the registration, on Form S-2 or Form
S-3 of all shares of Registration Stock which the Company has been requested to
register.  The Company shall not 

                                       20
<PAGE>
 
be required to effect any such registration more than once every twelve months.
Registrations effected on Form S-2 or Form S-3 shall not be considered to be
demand registrations pursuant to Section 8.2(a) hereof.

          (c)  The Company may include in a registration requested under this
Section 8.2 any additional authorized shares of the Common Stock of the Company,
whether or not issued, for sale by the Company or for sale by others; provided,
                                                                      -------- 
however, that such shares shall not be included to the extent that the holders
- -------                                                                       
of a majority of the shares of Registration Stock included therein determine in
good faith that the inclusion of such shares will interfere with the successful
marketing of the shares of Registration Stock to be included therein; and,
provided, further, that, upon the election of the holders of a majority of the
- --------  -------                                                             
shares of Registration Stock included therein, or if the number of shares to be
so included equals or exceeds the number of shares of Registration Stock
included therein by the holders of Registration Stock, such registration shall
be deemed to be a registration pursuant to Section 8.1(b) hereof.

          (d)  The underwriter and the terms of the underwriting for any
registration pursuant to this Section 8.2 shall be mutually acceptable to the
Company and the Investor.

          (e)  Notwithstanding anything contained in this Agreement to the
contrary:

                    (i)    The Company reserves the right to delay any such
registration pursuant to Section 8 for a period of not more than sixty days, or
to withhold efforts to cause such registration statement to become effective for
a period of not more than sixty days, if the Board of Directors of the Company
determines in good faith that such registration might (A) interfere with or
affect the negotiation or completion of any material transaction that is being
contemplated by the Company, or (B) involve initial or continuing disclosure
obligations materially adverse to the best interest of the Company's
shareholders. If, after a registration statement becomes effective, the Company
advises the holders of the Registration Stock covered by such registration
statement that the Company considers it appropriate for the registration
statement to be amended, the holders of such shares shall suspend any further
sales of their registered shares until the Company advises them that the
registration statement has been amended. The time periods referred to in this
Article 8 shall be extended for an additional number of business days during
which the rights to sell shares was suspended.

                    (ii)   The Company shall not be obligated to file a
registration statement pursuant to Section 8.2 within three months after the
effective date of any registration under which piggyback rights were granted
pursuant to Section 8.1.

     8.3  Further Obligations of the Company.  Whenever the Company is
          ----------------------------------                          
required to register any of the Registration Stock pursuant to any of the
provisions of this Section 8, the Company shall also be obligated to do the
following:

               (a)  Prepare for filing and file with the Securities and Exchange
Commission promptly thereafter a registration statement and such amendments and
supplements to said registration statement and the prospectus used in connection
therewith as may be 

                                       21
<PAGE>
 
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 (but, other than as
otherwise provided in Section 8.2(a), in no event more than nine months) to
complete the proposed public offering;

               (b)  Furnish to each selling holder so requesting such copies of
preliminary and final prospectus and such other documents as said holder may
reasonably request to facilitate the public offering of such holder's
Registration Stock;

               (c)  Use its best efforts to register or qualify the Registration
Stock covered by said registration statement under the securities or Blue Sky
laws of such jurisdictions as not less than 60% of the holders of Registration
Stock may reasonably request, to keep such registration or qualification in
effect for so long as such registration statement remains in effect, and do any
and all other acts and things that may be reasonably necessary or advisable to
enable such seller to consummate the disposition in such jurisdictions of its
Registration Stock covered by such registration statement, except that the
Company shall not for any such purpose be required to qualify generally to do
business as a foreign corporation in any jurisdiction wherein it would not, but
for the requirements of this subdivision (c), be obligated to be so qualified,
or to subject itself to taxation in any such jurisdiction, or to consent to
general service of process in any such jurisdiction;

               (d)  Furnish to the selling holders, and any underwriters or
broker-dealers through whom the Registration Stock may be sold, an opinion or
opinions of counsel for the Company and a "cold comfort" letter or letters of
the independent auditors for the Company, in form and substance customary for
similar offerings;

               (e)  Permit each selling holder or the selling holder's counsel
or other representatives, at the selling holder's expense, to inspect and copy
such corporate documents and records as may reasonably be requested by them;

               (f)  If so requested, furnish to each selling holder a copy of
all documents filed and all correspondence to or from the Securities and
Exchange Commission in connection with any such offering.

               (g)  Immediately notify each seller of Registration Stock covered
by such registration statement, at any time when a prospectus relating thereto
is required to be delivered under the Securities Act, upon discovery that, or
upon the happening of any event as a result of which, the prospectus included in
such registration statement, as then in effect, includes an untrue statement of
a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing, and at the request of any such seller or
holder, prepare and furnish to such seller and holder a reasonable number of
copies of a supplement to or an amendment of such prospectus as may be necessary
so that, as thereafter delivered to the purchasers of such Registration Stock,
such prospectus shall not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing;

                                       22
<PAGE>
 
               (h)  Otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering a period of at least twelve months, but not more
than eighteen months, beginning with the first month of the first fiscal quarter
after the effective date of such registration statement, which earnings
statement shall satisfy the provisions of subsection 11(a) of the Securities
Act;

               (i)  Provide and cause to be maintained a transfer agent and
registrar for all Registrable Securities covered by such registration statement
from and after a date not later than the effective date of such registration
statement; and

If requested by the company, each seller of Registration Stock as to which any
registration is being effected shall furnish the Company with such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing as shall be required by law or
by the Commission in connection therewith.

          8.4  Registration Rights Equal or Superior.  The Company shall not
               -------------------------------------                        
grant any registration rights or register any securities for the account of any
person other than holders of Registration Stock unless permitted to do so by the
written consent of the Required Holders; provided, however, that the Company
                                         --------  -------                  
shall be entitled to grant registration rights or register any securities for
the account of any person other than holders of Registration Stock without the
consent of the Designated Director as long as such rights applicable to such
securities are made subject and subordinate to, or no more than equal to the
rights of the holders of Registration Stock under Sections 8.1 and 8.2 (such
securities being the "Subordinate Shares").

          8.5  Expenses, Etc.  All expenses in connection with the preparation
               -------------                                                  
and filing of any registration statement under this Section 8, any registration
or qualification under the securities or Blue Sky laws of states in which the
offering will be made under such registration statement, and any filing fee of
the National Association of Securities Dealers, Inc. relating to such offering,
shall be borne in full by the Company, except for any (i) underwriters' or
brokers' commissions applicable to the shares to be sold by a holder of
Registration Stock, (ii) fees required to be paid by a selling shareholder
rather than the Company in order to comply with Blue Sky or state securities
laws, (iii) other fees or expenses expressly applicable to securities being sold
by the selling shareholder and (iv) fees or expenses of any selling
shareholders' counsel.

          8.6  Indemnification.  The Company shall indemnify the selling holders
               ---------------                                                  
of Registration Stock, and, to the extent required in any agreement with any
underwriter or broker-dealer through whom the Registration Stock may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities, expenses or actions in respect
thereof (under the Securities Act or common law or otherwise) caused by any
untrue statement or alleged untrue statement of a material fact contained in any
registration statement under which such Registration Stock were registered under
the Securities Act, any preliminary or final prospectus contained therein, or
any amendment or supplement thereto, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; and will reimburse the
selling holders of Registration Stock for any legal or other out-of-pocket
expenses reasonably incurred by such 

                                       23
<PAGE>
 
selling holders in connection with investigating or defending against such loss,
claim, damage, liability or action; except insofar as such losses, claims,
damages, liabilities or expenses are caused by any untrue statement or omission
contained in information furnished in writing to the Company by such selling
holders expressly for use therein. In connection with any such registration
statement, the selling holders of Registration Stock will furnish the Company in
writing such information as may reasonably be requested by the Company for use
in any such registration statement or prospectus and will indemnify the Company,
its directors and officers, and, to the extent required in any agreement with
any underwriter or broker-dealer, each such underwriter or broker-dealer and
each person, if any, who controls the Company or any underwriter or broker-
dealer (within the meaning of the Securities Act) against any losses, claims,
damages, liabilities, expenses and actions in respect thereof (under the
Securities Act or common law or otherwise) resulting from any untrue statement
or alleged untrue statement of a material fact required to be stated in such
registration statement or prospectus and necessary to make the statements
therein not misleading; and will reimburse the Company for any legal or other
out-of-pocket expenses reasonably incurred by it in connection with
investigating or defending against such loss, claim, damage, liability or
action; but only to the extent that such untrue statement or omission was
contained in information so furnished in writing by the selling holders of
Registration Stock expressly for use therein, and only to the extent of proceeds
received by the selling holders of Registration Stock in the offering. The
Company further agrees and the selling shareholder shall agree that, in
connection with any underwritten public offering, the Company also will enter
into customary contribution arrangements with the selling holders of
Registration Stock and the underwriters or broker-dealers through whom the
Registration Stock may be sold, with respect to situations in which
indemnification is potentially unavailable.

          8.7  Withdrawal.  If a public offering is not completed within nine
               ----------                                                    
months after the effective date of any registration statement filed by the
Company pursuant to Section 8.1(b), other than an offering under Rule 415 as
described in Section 8.2(a), the Company reserves the right, at its option, to
withdraw from registration any securities offered by the Company which have not
been sold during such period, provided that no securities offered by any holder
of Registration Stock shall be withdrawn without the consent of the holders of
50% of the Registration Stock.

          8.8  Exchange Act.  As promptly as possible following receipt of a
               ------------                                                 
written request therefor from the holders of 50% of the outstanding Registration
Stock at any time while the Company either (a) is subject to periodic reporting
pursuant to Section 15(d) of the Exchange Act or (b) has 300 or more
shareholders of record, the Company shall register its Common Stock under
Section 12 of the Exchange Act, arrange for its Common Stock to be listed on a
national stock exchange or included for quotation on Nasdaq or the Nasdaq
National Market, as requested, and shall keep effective such registration and
maintain such listing or inclusion, and shall use its best efforts timely to
file such information, documents and reports as the Securities and Exchange
Commission may require or prescribe that the Company file in connection
therewith.  The Company will, at the request of any holder of Registration
Stock, advise such holder in writing as to whether all reports required to be
filed by the Company under Section 13 of the Exchange Act during the 12 months
preceding such request (or for such shorter period as the Company was required
to file such reports) have been filed, and any other information which 

                                       24
<PAGE>
 
the holder may reasonably require in order to comply with Rule 144 under the
Act, or any other comparable rule, as then in effect.

     IX.  Preemptive Rights.
          ----------------- 

          9.1  Until the first to occur of (a) the Investor no longer owning the
Minimum Stock Amount or (b) the consummation of a Qualifying Public Offering, if
at any time after the date of this Agreement, the Company issues or proposes to
issue any equity securities, other than (a) the securities whose issuance is
contemplated by this Agreement; (b) up to an aggregate of 490,730 shares of
Common Stock issuable upon exercise of options granted under the ESOP; (c) up to
an aggregate of 123,700 shares of Common Stock issuable upon exercise of the
Harris Options, an aggregate of 144,438 shares of Common Stock issuable upon
exercise of the Deferral Options, an aggregate of 89,713 shares of Common Stock
issuable upon exercise of the Horton Options, an aggregate of 100,000 shares of
Common Stock issuable upon exercise of the Meridian Options; and (d) shares of
Common Stock issued upon the exercise, exchange or conversion of any security as
to which the Investor had an opportunity to exercise its rights under this
Section 9 (an "Issuance"), the Investor shall have the right to purchase up to
its Proportionate Percentage (as defined below) of the type of securities issued
or proposed to be issued in such Issuance on the same price and terms as the
Issuance (to the extent such price and terms are cash prices and terms).  The
Investor's "Proportionate Percentage" shall be that percentage equal to the
ratio which (x) the number of shares of outstanding Common Stock then owned by
the Investor bears to (y) the aggregate number of shares of outstanding Common
Stock then owned by all shareholders of the Company.  For purposes solely of the
computation required under clauses (x) and (y) above, the Investor holding
Preferred Stock shall be treated as having converted all of its Preferred Stock
into shares of Common Stock at the rate at which such Preferred Stock is
convertible at the time of delivery by the Company of the Option Notice (as
defined in Section 9.2), assuming that all outstanding Preferred Stock held by
other Holders of Preferred Stock shall likewise be deemed converted.

          9.2  In the event of an Issuance, the Company shall deliver to the
Investor a written notice describing such Issuance, specifying the Investor's
pro rata share and stating the purchase price and other terms of such Issuance
(the "Option Notice").  For a period of 45 days from the receipt of the Option
Notice, the Investor shall have the right to elect, by written notice to the
Company, to purchase all or any portion of its pro rata share of such
securities.

     X.   Participation Rights.
          -------------------- 

          10.1 In addition to and not in limitation of the provisions of the
Shareholders' Agreement, the Founder hereby agrees that until the first to occur
of (a) the Investor no longer owning the Minimum Stock Amount or (b) the
consummation of a Qualifying Public Offering, he shall not sell any of the
shares of the capital stock of the Company held by him, unless such sale is in
accordance with the terms and conditions of this Section 10.

          10.2 Until the consummation of a Qualifying Public Offering, in the
event that the Founder desires to sell some or all of the shares of the capital
stock of the Company held by him (the "Offered Shares") in a private transaction
then the Founder shall obtain a written offer 

                                       25
<PAGE>
 
(the "Offer") to purchase such Offered Shares solely for cash to be paid in full
at the closing of each such transaction, and shall forward a copy of the Offer
to the Company and to the Investor.

          10.3 If, within 30 days of receipt of the Offer, the Company notifies
the Founder that it will purchase all of the Offered Shares, then the Founder
shall sell such shares to the Company upon the terms and conditions of the
Offer.

          10.4 If the Company declines to purchase all or any portion of the
Offered Shares in accordance with Section 10.3 above, it shall promptly notify
the Investor of such decision.  If, within 30 days of receipt of such notice,
the Investor notifies the Founder that it will purchase all or any portion of
the remaining offered Shares, then the Founder shall sell such shares to the
Investor upon the terms and conditions of the Offer.

          10.5 If, after giving effect to Sections 10.3 and 10.4 above, the
Company and the Investor fail to purchase all of the Offered Shares, then the
Founder shall be entitled to sell such shares on the terms set forth in the
Offer for a period of 30 days, commencing upon the expiration of the 30-day
period referred to in Section 10.4 above, subject to the provisions of Section
10.6 below.

          10.6 If, after giving effect to Sections 10.3 and 10.4 above, the
Company and the Investor do not agree to purchase all of the Offered Shares,
then the Founder shall use Founder's best efforts to interest the offeror (the
Offeror") in purchasing such shares as the Investor gives notice that it desires
to sell in such sale (the "Additional Shares"), as well as the Offered Shares.
If the Offeror does not wish to purchase the full amount of the Additional
Shares, then the Investor shall be entitled to sell in the transaction up to
that number of the Additional Shares which, when divided by the total number of
Additional Shares as to which the Investor has given notice that it desires to
sell in the transaction, would be equal to the number of shares which the
Offeror has agreed to purchase, divided by the aggregate number of shares which
the Founder and the Investor sought to sell to the Offeror.

          10.7 Other than as set forth above, without the prior written consent
of the Investor, the Founder may not make any transfer of such Founder's shares
of the capital stock of the company in any transaction not permitted by the
Shareholders' Agreement.

     XI.  Events of Default.
          ----------------- 

          Each of the following shall constitute an Event of Default under this
     Agreement:

          11.1 Default on Payments to the Investor.  The failure of the Company
               -----------------------------------                             
to make (a) within ten days of the date when due, any principal or interest
payment on any Note, any dividend payment upon the Preferred Stock on the date
when due, or any other payment required to be made on the date when due (whether
under the terms of the Notes, the Prior Notes, the Preferred Stock or the
Amendment) in connection with the redemption of the Preferred Stock or under the
terms of the Notes or the Prior Notes, or (b) failure of the Company to make any
other payment upon any other note, guaranty or obligation of the Company to the
Investor or held by the Investor, or required hereunder, within 30 days after
written notice from the Investor to the Company; regardless of whether any such
failure to make the payments described in (a) and (b) above is due to a legal
inability or incapacity of the Company to make any such payments.

                                       26
<PAGE>
 
          11.2 Information, Representations and Warranties.  Any information
               -------------------------------------------                  
furnished or representation or warranty made or given by the Company herein
shall prove to have been untrue when made or given in any material respect or
shall have omitted to state a material fact respecting the matters set forth
therein necessary to make the matters set forth therein not misleading.

          11.3 Covenants and Agreements.  The failure of the Company to observe,
               ------------------------                                         
perform or abide by any other covenant, warranty, agreement or provision of this
Agreement, the Prior Purchase Agreement, the Amendment, the Notes, the Prior
Notes, the Warrants, the Prior Warrants, the Preferred Stock, or any of the
documents executed by the Company in connection herewith or therewith or
referred to herein or therein, which failure is not cured to the Investor's
reasonable satisfaction within 30 days (the "Cure Period") after written notice
from the Investor to the Company of its occurrence; provided, however, that no
                                                    --------  -------         
Event of Default shall be considered to have occurred if the failure is not the
failure to pay money and is of such a nature that it reasonably cannot be cured
within the Cure Period, but if it is curable and the Company in good faith
begins efforts to cure it within the Cure Period and continues diligently to do
so, the Company shall have an additional 30 days from the date on which the Cure
Period ends to effect the cure.  If the failure continues after the expiration
of such additional 30 day period, regardless whether such failure might be
curable at some time beyond such additional 30 day period, such failure shall
nevertheless be considered an Event of Default.

          11.4 Default on Other Obligations.  The occurrence of a material
               ----------------------------                               
default following the expiration of any applicable cure period, if any, in any
material obligation of the Company or any violation of law or refusal of
regulatory permission which has a material adverse effect on the Company's
operations.

          11.5 Certain Events As To The Company.  The Company or any of its
               --------------------------------                            
material subsidiaries shall (A) admit in writing its inability to pay its debts
generally as they become due; (B) file a petition or answer or consent seeking
relief under the Federal Bankruptcy Code, as now constituted or hereafter
amended, or any other applicable federal or state bankruptcy or insolvency law
or other similar law, not discharged or vacated or set aside or stayed within 45
days; (C) consent to the institution of proceedings under any law referenced in
(B) above, not discharged or vacated or set aside or stayed within 45 days, or
to the filing of any such petition, not discharged or vacated or set aside or
stayed within 45 days or to the appointment or taking possession of a receiver,
liquidator, assignee, trustee, custodian (or other similar official) of the
Company or any subsidiary or of any substantial part of their property; (D) fail
generally to pay its debts as such debts become due, or take corporate action in
furtherance of any such action; (E) make an assignment for the benefit of its
creditors; or (F) fail to meet any of its material monetary obligations with the
exception of trade payables, in the amounts and for the periods set forth on
Schedule 2.2 attached hereto; provided, however, that no Event of Default shall
- ------------                  --------  -------                                
be considered to have occurred under subsection 11.5(F) if the failure to meet
such material monetary obligations is due to a good faith dispute between such
parties, which dispute shall continue for no more than 30 days; provided
                                                                --------
further, that upon the expiration of such 30 day period (the "Expiration Date"),
- -------
the Company shall have, upon notice to the Investor an additional 30 day period
to resolve the dispute.  If the dispute is not resolved after the expiration of
such additional 30 day period, regardless whether such dispute may be resolved
at some time beyond 

                                       27
<PAGE>
 
such additional 30 day period, such failure under subsection 11.5(F) shall
nevertheless be considered an Event of Default.

          11.6 Certain Events As To The Founder.  The Founder dies, is disabled
               --------------------------------                                
for a period in excess of 120 days during which the Founder is unable to perform
his duties as an officer of the Company for a full eight hour day (the
"disability" of the Founder), terminates his employment with the Company or has
his employment terminated by the Company.

     XII. Rights of Investor Upon Default.
          ------------------------------- 

          12.1 Rights on Default.  If there shall occur and be continuing an
               -----------------                                            
Event of Default as defined in the foregoing Section 11, the Investor, or if
there are then Holders of Preferred Stock, the Holders of at least 75% of the
Preferred Stock may, by written notice to the Company, declare the Company to be
in default hereunder, whereupon: (i) if the Investor or the Holders of at least
75% of the Preferred Stock, as applicable, so specifies in such notice, any
Notes then outstanding, the balance of all accrued dividends upon the Preferred
Stock, and all other indebtedness of the Company to the Investor now or
hereafter incurred, shall become immediately due and payable without further
demand, presentation or notice of any kind; and (ii) the Founder hereby agrees
that, at such time, he shall vote his shares in such a manner and take such
actions as may be necessary or advisable, in the reasonable opinion of the
Investor or the Holders of at least 75% of the Preferred Stock, to best ensure
the repayment of the Notes and the Prior Notes and payment of all such accrued
dividends upon the Preferred Stock and repayment of all such other indebtedness
to the Investor.

          12.2 Additional Rights.  The Investor shall have such additional
               -----------------                                          
rights and remedies as are contained herein, in the Notes, the Warrants, the
Preferred Stock, the Amendment, or in any other documents and agreements
delivered or given in connection herewith, and all rights which it might have at

to effectuate the transactions provided for herein.  The parties shall cooperate
fully with each other and with their respective counsel and accountants in
connection with any steps required to be taken as part of their respective
obligations under this Agreement.

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

          14.1 Waivers and Amendments.  No waiver by either party of any
               ----------------------

     4.   REPRESENTATIONS AND WARRANTIES OF INVESTOR AND RESTRICTIONS ON
TRANSFER.

          4.1  REPRESENTATIONS AND WARRANTIES BY THE INVESTOR. The Investor
represents and warrants to the Company as follows:

               (a)  The Investor (i) is acquiring the Debenture and the Warrants
          and (ii) upon conversion of the Debenture or the Class B Preferred
          Stock, or upon exercise of the Warrants, will acquire the applicable
          Conversion Shares then issuable, for investment for its own accounts
          and not with a view to, or for resale in connection with, any
          distribution of the Securities. The Investor understands that the
          Securities have not been registered under the Securities Act, or under
          any state securities or "Blue Sky" laws, and, as a result, are subject
          to substantial restrictions on transfer. The Investor acknowledges
          that the Securities must be held indefinitely unless subsequently
          registered under the Securities Act and any applicable state
          securities or "Blue Sky" laws, or exemptions from registration under
          the Securities Act and such laws are available; provided, however,
          that by making the representations herein, the Investor does not agree
          to hold any of the Securities for any minimum or other specific term
          and reserves the right to dispose of the Securities at any time in
          accordance with or pursuant to a registration statement or an
          exemption from registration under the Securities Act and any
          applicable state securities or "Blue Sky" laws.

                                       10
<PAGE>
 
               (b)  This Agreement has been duly executed and delivered by the
          Investor and constitutes a valid and legally binding obligation of the
          Investor, enforceable in accordance with its terms, subject, as to
          enforcement, to bankruptcy, insolvency, reorganization and other laws
          of general applicability relating to or affecting creditors rights and
          to general equity principles.

               (c)  The Investor is an "accredited investor," as that term is
          defined in Rule 501(a) of Regulation D under the Securities Act.

               (d)  The Investor is an "institutional buyer" and, accordingly,
          the offer and sale of the Securities to the Investor is an exempt
          transaction pursuant to Section 7309(b)(8) of the Delaware Securities
          Act.

          4.2  LEGENDS. The Investor understands that the certificates or other
instruments representing the Debenture and the Warrants and, until such time as
the sale of the Conversion Shares have been registered under the Securities Act,
the stock certificates representing the Conversion Shares, except as set forth
below, shall bear a restrictive legend in substantially the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
          SECURITIES LAWS AND MAY NOT BE TRANSFERRED IN THE ABSENCE OF SUCH
          REGISTRATION OR AN EXEMPTION THEREFROM UNDER SUCH ACT AND SUCH LAWS.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped if, unless otherwise required by state securities laws, (i) such
Securities are registered for sale under the Securities Act, (ii) in connection
with a sale transaction, such holder provides the Company with an opinion of
counsel, in a form reasonably acceptable to the Company's counsel, to the effect
that a public sale, assignment or transfer of such Securities may be made
without registration under the Securities Act, or (iii) such holder provides the
Company with an opinion of counsel, in a form reasonably acceptable to the
Company's counsel, that such Securities can be sold pursuant to Rule 144(k)
promulgated under the Securities Act (or a successor rule thereto) ("Rule 144").
The Investor acknowledges, covenants and agrees to sell the Securities
represented by a certificate(s) from which the legend has been removed, only
pursuant to (i) a registration statement effective under the Securities Act, or
(ii) advice of counsel that such sale is exempt from registration required by
Section 5 of the Securities Act.

     5.   CONTINUATION AND SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties shall survive the consummation of the
transactions provided for in the Transaction Documents for a period beginning on
the date hereof up to and including the earlier of the conversion of all Class B
Preferred Stock held by the Investor into Common Stock or December 31, 1999;
provided, however, that such period shall not end prior to December 31, 1998. No
such representation or warranty shall be deemed to have been waived, affected or
impaired by any investigation made by any person or persons.

     6.   AFFIRMATIVE COVENANTS OF THE COMPANY.  The Company hereby covenants to
comply with the following affirmative covenants, unless waived by the Investor,
as long as the Debenture remains outstanding; provided, however, that in the
event the Debenture is converted into shares of Class B Preferred Stock, the
Company shall provide to the Investor all such information and rights as the
Company provides to any other holder of Class B Preferred Stock, whether
pursuant to the Company's Articles of Incorporation, as amended, contract or
otherwise; and provided, further, that the Company shall comply with Section
6.2, unless waived by the Investor, until the earlier of (i) such time as the
Investor owns no Debenture, no Warrants, no Class B Preferred Stock and fewer
than 100,000 shares of Common Stock or (ii) the closing of an underwritten
initial public offering of any of the Company's securities under the Securities
Act (or any successor statute), yielding gross proceeds to the Company of at
least $7,500,000.

          6.1  FINANCIAL STATEMENTS.  The Company shall furnish to the Investor
the following financial statements, reports and other documents, such financial
statements to be prepared in accordance with generally accepted accounting
principles consistently applied, certified by the Company's chief executive or
financial officer:

               (a) as soon as available, and in any event within 90 days after
          the end of each fiscal year of the Company, a balance sheet of the
          Company as of the end of such fiscal year and related statements of
          operations, shareholders' equity and cash flows for such fiscal year,
          all in reasonable detail and setting forth in comparative form the
          figures as of the end of and for the previous fiscal year, which
          financial statements shall have been audited, and shall be accompanied
          by an unqualified opinion addressed to the Company from "Big Six"
          independent auditors or other independent auditors that are reasonably
          satisfactory to the Investor, together with a copy of such auditors'
          letter to Company's management;

               (b) as soon as available, and in any event within 20 days after
          the end of each month for such month and for the year to date, an
          unaudited balance sheet and unaudited statements of operations,
          shareholders' equity and cash flows, together with a comparison of
          such financial statements with the budget of the Company for such
          period; and

               (c) as soon as available, and in any event at least 60 days prior
          to the end of each fiscal year of the Company, an annual budget and
          business plan for the subsequent fiscal year, which budget and
          business plan shall include a monthly breakdown of financial
          statements, which breakdown shall include the underlying assumptions
          and a brief qualitative description of the Company's plan by the
          Company's Chief Executive Officer in support of such budget and
          business plan, which also shall have been approved and accepted by the
          Board of Directors of the Company. If during the course of operations
          for any such month it becomes apparent that deviations from such
          financial statements, budget and business plan have occurred, the
          Company shall submit to its Board of Directors a statement of such
          deviation within five business days from the date of the Company's
          knowledge of such deviation (the "Statement"). The Statement shall
          detail the manner in which a new financial projection deviates from
          the annual business plan and the reason therefor. The Board of
          Directors shall have the right to ask

                                       12
<PAGE>
 
          questions or request any other reasonable additional information with
          respect to the Statement. Any and all subsequent deviations from such
          financial statements shall be resubmitted to the Board of Directors of
          the Company for approval and acceptance or for required further
          revision until such approval and acceptance is obtained.

In the event that the Company at any time hereafter is required, by law or by
generally accepted accounting principles, to consolidate its financial
statements with those of a subsidiary corporation, the Company shall thereafter
furnish the financial statements required by this Section 6.1 on a consolidated
basis, and the monthly and annual financial statements specified above shall be
furnished with consolidating financial statements.

          6.2  BOARD OF DIRECTORS, MEETINGS.  The Company shall maintain By-laws
provisions satisfactory to the Investor in its sole discretion with respect to
the following provisions and use its best efforts to achieve the following
objectives:
               (a) Subject to the terms of this Agreement, the Investor shall
          have the right to designate one person to serve as a member of the
          Board of Directors (the "Designated Director").  The Investor hereby
          designates Walter L. Threadgill as its first Designated Director and
          the Company hereby agrees to Mr. Threadgill to be elected to the
          Company's Board of Directors as promptly as possible.  The Investor
          shall also have the right to replace the Designated Director from time
          to time and at any time during the Applicable Period.  In that regard,
          the Company agrees to take all necessary action to cause any person
          named by the Investor during the Applicable Period as a replacement
          Designated Director to be elected to the Company's Board of Directors
          in replacement of the previous Designated Director as promptly as
          possible thereafter.  In the event the Company establishes an
          Executive Committee of the Board of Directors (or any other similar
          committee), one member of any such committee shall be the Designated
          Director.  The Company shall reimburse the Designated Director for all
          reasonable travel and other expenses incurred in connection with such
          Director's participation on the Board of Directors or any committee of
          the Board of Directors.

               (b) The Company shall not hold any meetings of the Board of
          Directors (or any other similar meetings) until such time as the
          Designated Director has been elected to the Company's Board of
          Directors.

               (c) The Company shall permit the Designated Director to invite
          one or more additional individuals to any and all meetings of the
          Board of Directors or of the shareholders of the Company; provided,
          however, that the individual invited must be a director, officer,
          consultant or employee of the Investor. Such individuals may
          participate in discussions and express their views on matters before
          the Board of Directors, but shall not be entitled to vote. Such
          attendance may be either in person or by telephone.

          information concerning the Company which is furnished to the Investor
          by the Company and designated as confidential, except as required by
          law, legal process or its fiduciary duty to report financial and
          business information to its partners, shareholders, directors or
          affiliates and to such other persons as the Investor, in the exercise
          of

                                       14

          its prudent business judgment, may select and shall use reasonable
          commercial efforts to have such persons maintain such confidentiality
          of the confidential information. The term "confidential information"
          does not include information which (i) was or becomes generally
          available to the public other than as a result of a disclosure by the
          Investor, or (ii) was or becomes available to the Investor on a non-
          confidential basis from a source other than the Company, provided that
          such source is not bound by a confidentiality agreement with the
          Company.

          6.4  INSPECTION.  The Company shall permit, at any reasonable time and
from time to time upon reasonable advance notice, the Investor or its duly

Company with any of the Company's officers, consultants, directors or
independent accountants.

an insurance company or association satisfactory to the Investor, on the life of
Frank Wilde and Michael Harris, each in the amount of $1,500,000 payable, until
conversion or payment of the Debenture, to the Investor, and the amount of the
insurance so obtained shall not be decreased or cancelable other than due to the
non-payment of premiums or prior conversion or repayment of the Debenture.
Assuming issuance of such a life insurance policy or policies as to which the
Investor is the beneficiary, upon the death of Mr. Wilde or Mr. Harris, the
Investor shall accelerate the Debenture and the proceeds of such policy shall be
used to repay all then outstanding principal and interest under the Debenture,
to the extent of such policy or policies.  To the extent the proceeds of such
life insurance policy exceed all amounts due under the Debenture, the Investor
shall remit to the Company such excess remaining after all amounts due on the
Debenture have been fully satisfied.

marks, and other proprietary rights.

          6.8  BOOKS AND RECORDS.  The Company shall make and keep books,

its transactions, and shall devise and maintain a system of internal accounting
controls sufficient to provide reasonable assurances that: (a) transactions are

recorded assets are compared with existing assets at reasonable intervals and
appropriate action is taken with respect to any difference.

          6.9  OTHER INSURANCE.  The Company shall maintain insurance against

rules and regulations of all governmental authorities and agencies applicable to

          7.5  INSIDER TRANSACTIONS.  Except as disclosed in Schedules 3.21 and
                                                             --------------    
3.22, the Company shall not enter into any transaction with any of its officers,
- ----

Notwithstanding the foregoing, the Company shall obtain the prior written
approval of the Investor or the Designated Director with respect to any material

     8.   REGISTRATION AND RELATED RIGHTS.

          8.1  PIGGYBACK REGISTRATION.

               (a) As used in this Section 8.1, "Registration Stock" shall mean
          any Securities or any other shares of Common Stock, Class B Preferred
          Stock or other securities received by holders of the Securities upon
          any stock split, stock dividend, recapitalization, merger,
          consolidation or similar event; provided, however, that Registration
          Stock shall not include any Securities or such other securities
          disposed of pursuant to one or more registration statements under the
          Securities Act, or which have been sold pursuant to Rule 144 (as
          previously defined) or which have otherwise been sold without
          registration under the Securities Act.  For purposes of this Section
          8, any record holder of securities convertible into Registration Stock
          (or exercisable for or payable in Registration Stock) shall be deemed
          to be the holder of the Registration Stock issuable upon such
          conversion and/or exercise and/or payment.

               (b) If the Company should seek to register under the Securities
          Act or qualify any of the securities holdings of the Company or any of
          its shareholders (except in connection with any stock option plan,
          stock purchase plan, savings or similar plan or an acquisition, merger
          or exchange of stock, to be registered on Forms S-4, S-8 or any
          successor forms under the Securities Act) and if the form of
          registration statement proposed to be used otherwise may be used for
          the registration of the Registration Stock, then, on each such
          occasion, the Company shall furnish the Investor with at least 30 days
          prior written notice thereof.  At the written request of the Investor,
          given within 20 days after the receipt of such notice, the Company
          will use its best efforts to cause all of the Registration Stock for
          which registration shall have been requested by the Investor to be
          included in such registration statement.  In the event that the
          proposed registration by the Company is, in whole or in part, an
          underwritten public offering of securities of the Company, and the
          managing underwriter determines and advises in writing that the
          inclusion of all Registration Stock proposed to be included in the
          underwritten public offering and other issued and outstanding shares
          of Common Stock proposed to be included therein by persons other than
          (i) holders of Registration Stock or (ii) holders of Subordinate
          Shares (as defined in Section 

                                       18
<PAGE>
 
          8.4) with rights equal to those of the holders of Registration Stock
          ("Other Registration Stock") (such other shares which are not
          Registration Stock or Other Registration Stock being the "Other
          Shares") would interfere with the successful marketing (including
          pricing) of the securities, then the number of shares of Registration
          Stock, Other Registration Stock and Other Shares to be included in
          such underwritten public offering shall be reduced first, pro rata
          among the holders of Other Shares; second, if necessary, pro rata
          among the holders of Registration Stock and Other Registration Stock
          combined, based on the number of shares requested by holders thereof
          to be registered in such underwritten public offering; and lastly, if
          necessary, among the Company's shares requested by the Company to be
          registered; provided, however, that the holders of Registration Stock
          do not then elect to exercise their rights under Section 8.2; and,
          further provided, that in no event, without the consent of the holders
          of at least 67% of the Registration Stock, shall the percentage of the
          Registration Stock that is included in such registration statement be
          less than the percentage of the securities of any other shareholder
          included therein. In the event that the Company offers any of its
          securities in an offering exempt from registration under the
          Securities Act pursuant to Regulation A, the Company will provide to
          the holders of Registration Stock rights comparable to those provided
          herein.

     8.2  DEMAND REGISTRATION.

               (a) After the closing of an underwritten offering of the Common
          Stock, if at any time the Company is requested in writing by the
          holders of not less than 67% of the Registration Stock to effect the
          registration under the Securities Act of at least 33 1/3% of the
          Registration Stock, the Company shall promptly give written notice of
          such proposed registration to all record holders of Registration
          Stock.  Such holders shall have the right, by giving written notice to
          the Company within 30 days from receipt of the Company's notice, to
          elect to have included in such registration such of their Registration
          Stock as such holders may request in such notice of election.
          Thereupon, the Company shall, as expeditiously as possible, use its
          best efforts to effect the registration, on a form of general use
          under the Securities Act of all shares of Registration Stock which the
          Company has been requested to register; provided, however, that if the
          holders of not less than 67% of the Registration Stock shall so
          request (and at least 50% of the Registration Stock is being
          registered), the Company shall file such registration statement
          pursuant to Rule 415 or any successor rule or regulation under the
          Securities Act, so as to permit the continuous or delayed offering of
          the Registration Stock in accordance with the intended method of
          disposition specified in the notice of the exercise of rights under
          this Section 8.2(a), to the extent such offering qualifies under such
          rule or regulation, but in no event shall the Company be required to
          maintain the effectiveness of such registration statement beyond a two
          year period.  The Company shall be obligated to cause to become
          effective one registration statement pursuant to which Registration
          Stock is sold under this Section 8.2(a).

                                       19
<PAGE>
 
               (b) In addition and not in limitation of the rights set forth in
          Sections 8.1 (b) and 8.2(a), at such time as the Company shall have
          qualified for the use of a short form Form S-3 in an offering solely
          for the accounts of persons other than the Company (or any similar
          form or forms promulgated by the Securities and Exchange Commission),
          the holders of not less than 67% of the Registration Stock shall have
          the right to request an unlimited number of registrations on Form S-3
          or other similar forms.  Such holders shall have the right, by giving
          written notice to the Company within 20 days from receipt of the
          Company's notice, to elect to have included in such registration such
          of their Registration Stock as such holders may request in such notice
          of election.  Thereupon, the Company shall, as expeditiously as
          possible, use its best efforts to effect the registration, on Form S-3
          of all shares of Registration Stock which the Company has been
          requested to register.  The Company shall not be required to effect
          any such registration more than once every twelve months.
          Registrations effected on Form S-3 shall not be considered to be
          demand registrations pursuant to Section 8.2(a) hereof.

               (c) The Company may include in a registration requested under
          this Section 8.2 any additional authorized shares of the Common Stock
          of the Company, whether or not issued, for sale by the Company or for
          sale by others; provided, however, that such shares shall not be
          included to the extent that the holders of a majority of the shares of
          Registration Stock included therein determine in good faith that the
          inclusion of such shares will interfere with the successful marketing
          of the shares of Registration Stock to be included therein; and,
          provided, further, that, upon the election of the holders of a
          majority of the shares of Registration Stock included therein, or if
          the number of shares to be so included equals or exceeds the number of
          shares of Registration Stock included therein by the holders of
          Registration Stock, such registration shall be deemed to be a
          registration pursuant to Section 8.1(b) hereof.

               (d) The underwriter and the terms of the underwriting for any
          registration pursuant to this Section 8.2 shall be mutually acceptable
          to the Company and the Investor.

               (e) Notwithstanding anything contained in this Agreement to the
          contrary:
                         (i) The Company reserves the right to delay any such
                   registration pursuant to Section 8 for a period of not more
                   than sixty days, or to withhold efforts to cause such
                   registration statement to become effective for a period of
                   not more than sixty days, if the Board of Directors of the
                   Company determines in good faith that such registration might
                   (A) interfere with or affect the negotiation or completion of
                   any material transaction that is being contemplated by the
                   Company, or (B) involve initial or continuing disclosure
                   obligations materially adverse to the best interests of the
                   Company's shareholders. If, after a registration statement
                   becomes effective, the Company advises the holders of the
                   Registration

                                       20
<PAGE>
 
                   Stock covered by such registration statement that the Company
                   considers it appropriate for the registration statement to be
                   amended, the holders of such shares shall suspend any further
                   sales of their registered shares until the Company advises
                   them that the registration statement has been amended. The
                   time periods referred to in this Section 8 shall be extended
                   for an additional number of business days during which the
                   rights to sell shares was suspended.

                         (ii) The Company shall not be obligated to file a
                   registration statement pursuant to Section 8.2 within three
                   months after the effective date of any registration under
                   which piggyback rights were granted pursuant to Section 8.1.

          8.3  FURTHER OBLIGATIONS OF THE COMPANY.  Whenever the Company is
required to register any of the Registration Stock pursuant to any of the
provisions of this Section 8, the Company shall also be obligated to:

               (a) prepare for filing and file with the Securities and Exchange
          Commission promptly thereafter a registration statement and such
          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 (but, other than as otherwise provided in Section 8.2(a), in
          no event more than nine months) to complete the proposed public
          offering;

               (b) furnish to each selling holder so requesting such copies of
          preliminary and final prospectus and such other documents as said
          holder may reasonably request to facilitate the public offering of
          such holder's Registration Stock;

               (c) use its best efforts to register or qualify the Registration
          Stock covered by said registration statement under the securities or
          "Blue Sky" laws of such jurisdictions as the holders of Registration
          Stock may reasonably request, to keep such registration or
          qualification in effect for so long as such registration statement
          remains in effect, and do any and all other acts and things that may
          be reasonably necessary or advisable to enable such seller to
          consummate the disposition in such jurisdictions of its Registration
          Stock covered by such registration statement, except that the Company
          shall not for any such purpose be required to qualify generally to do
          business as a foreign corporation in any jurisdiction wherein it would
          not, but for the requirements of this subdivision (c), be obligated to
          be so qualified, or to subject itself to taxation in any such
          jurisdiction, or to consent to general service of process in any such
          jurisdiction;

               (d) furnish to the selling holders, and any underwriters or
          broker-dealers through whom the Registration Stock may be sold, an
          opinion or opinions 

                                       21

          discovery that, or upon the happening of any event as a result of
          which, the prospectus included in such registration statement, as then

          untrue statement of a material fact or omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading in the light of the circumstances then

from time to time reasonably request in writing as shall be required by law or
by the Securities and Exchange Commission in connection therewith.

          8.4  REGISTRATION RIGHTS EQUAL OR SUPERIOR.  The Company shall not
grant any registration rights or register any securities for the account of any
person other than holders of Registration Stock unless permitted to do so by (i)
the written consent of the holders of not less than 67% of the Registration
Stock, and (ii) the consent of the Designated Director; provided, however, that
the Company shall be entitled to grant registration rights or register any
securities for the account of any person other than holders of Registration
Stock without the consent of the Designated Director as long as such rights
applicable to such securities are made subject and subordinate to, or no more
than equal to the rights of the holders of Registration Stock under Sections 8.1
and 8.2 (such securities being the "Subordinate Shares").

          8.5  EXPENSES, ETC.  All expenses in connection with the preparation
and filing of any registration statement under this Section 8, any registration
or qualification under the securities or "Blue Sky" laws of states in which the
offering will be made under such registration statement, and any filing fee of
the National Association of Securities Dealers, Inc. relating to such offering,
shall be borne in full by the Company, except for any (i) underwriters' or
brokers' commissions applicable to the shares to be sold by a holder of
Registration Stock, (ii) fees required to be paid by a selling shareholder
rather than the Company in order to comply with "Blue Sky" or state securities
laws, (iii) other fees or expenses expressly applicable to securities being sold
by the selling shareholder, and (iv) fees or expenses of any selling
shareholders' counsel.

          8.6  INDEMNIFICATION.  The Company shall indemnify the selling holders
of Registration Stock, and, to the extent required in any agreement with any
underwriter or broker-dealer through whom the Registration Stock may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities, expenses or actions in respect
thereof (under the Securities Act or common law or otherwise) caused by any
untrue statement or alleged untrue statement of a material fact contained in any
registration statement under which such Registration Stock were registered under
the Securities Act, any preliminary or final prospectus contained therein, or
any amendment or supplement thereto (unless cured by an amendment or supplement
to the prospectus delivered to the selling holders prior to the sales of the
Registration Stock that are subject to the claimed right of indemnification), or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registration Stock
that are subject to the claimed right of indemnification); and will reimburse
the selling holders of Registration Stock for any legal or other out-of-pocket
expenses reasonably incurred by such selling holders in connection with
investigating or defending against such loss, claim, damage, liability or
action; except insofar as such losses, claims, damages, liabilities or expenses
are caused by any untrue statement or omission contained in information
furnished in writing to the Company by such selling holders expressly for use
therein.  In connection with any such registration statement, the selling
holders of Registration Stock will furnish the company in writing such
information as may reasonably be requested by the company for use in any such
registration statement or prospectus and will indemnify the Company, its
directors and officers, and, to the extent required in any agreement with any
underwriter or broker-dealer, each such underwriter or broker-dealer and each
person, if any, who controls the Company or any underwriter or broker-dealer
(within the meaning of the Securities Act) against any losses, 

                                       23
<PAGE>
 
claims, damages, liabilities, expenses and actions in respect thereof (under the
Securities Act or common law or otherwise) resulting from any untrue statement
or alleged untrue statement of a material fact required to be stated in such
registration statement or prospectus and necessary to make the statements
therein not misleading; and will reimburse the Company for any legal or other
out-of-pocket expenses reasonably incurred by it in connection with
investigating or defending against such loss, claim, damage, liability or
action; but only to the extent that such untrue statement or omission was
contained in information so furnished in writing by the selling holders of
Registration Stock expressly for use therein, and only to the extent of proceeds
received by the selling holders of Registration Stock in the offering. The
Company further agrees and the selling shareholders shall agree that, in
connection with any underwritten public offering, the Company also will enter
into customary contribution arrangements with the selling holders of
Registration Stock and the underwriters or broker-dealers through whom the
Registration Stock may be sold, with respect to situations in which
indemnification is potentially unavailable.

          8.7  WITHDRAWAL.  If a public offering is not completed within nine
months after the effective date of any registration statement filed by the
Company pursuant to Section 8.1 (b), other than an offering under Rule 415 as
described in Section 8.2(a), the Company reserves the right, at its option, to
withdraw from registration any securities offered by the Company which have not
been sold during such period, provided that no securities offered by any holder
of Registration Stock shall be withdrawn without the consent of the holders of
50% of the Registration Stock.

          8.8  EXCHANGE ACT.  As promptly as possible following receipt of a
written request therefor from the holders of 50% of the outstanding Registration
Stock at any time while the Company either (a) is subject to periodic reporting
pursuant to Section 15(d) of the Exchange Act or (b) has 300 or more
shareholders of record, the Company shall register its Common Stock under
Section 12 of the Exchange Act, arrange for its Common Stock to be listed on a
national stock exchange or included for quotation on the Nasdaq National Market,
as requested, and shall keep effective such registration and maintain such
listing or inclusion, and shall use its best efforts timely to file such
information, documents and reports as the Securities and Exchange Commission may
require or prescribe that the Company file in connection therewith.  The Company
will, at the request of any holder of Registration Stock, advise such holder in
writing as to whether all reports required to be filed by the Company under
Section 13 of the Exchange Act during the 12 months preceding such request (or
for such shorter period as the Company was required to file such reports) have
been filed, and any other information which the holder may reasonably require in
order to comply with Rule 144, or any other comparable rule, as then in effect.

     9.   EVENTS OF DEFAULT.

     Each of the following shall constitute an Event of Default under this
Agreement:

          9.1  DEFAULT ON PAYMENTS TO THE INVESTOR.  The failure of the Company
to make (a) any principal or interest payment on the Debenture when due, or (b)
any other payment upon any other written obligation of the Company to the
Investor within 15 days after written notice from the Investor to the Company;
regardless of whether any such failure to make the 

                                       24
<PAGE>
 
payments described in (a) and (b) above is due to a legal inability or the
incapacity of the Company to make any such payments.

          9.2  INFORMATION, REPRESENTATIONS AND WARRANTIES.  Any information
furnished or representation or warranty made or given by the Company herein
shall prove to have been untrue when made or given in any material respect or
shall have omitted to state a material fact respecting the matters set forth
therein necessary to make the matters set forth therein not misleading.

          9.3  COVENANTS AND AGREEMENTS.  The failure of the Company to observe,
perform or abide by any other covenant, warranty, agreement or provision in any
of the Transaction Documents, which failure is not cured to the Investor's
reasonable satisfaction within 30 days after written notice from the Investor to
the Company of its occurrence; provided, however, that no Event of Default shall
be considered to have occurred if the failure is not the failure to pay money
and is of such a nature that it reasonably cannot be cured within the Cure
Period, but if it is curable and the Company in good faith begins efforts to
cure it within the Cure Period and continues diligently to do so, the Company
shall have an additional 30 days from the date on which the Cure Period ends to
effect the cure.  If the failure continues after the expiration of such
additional 30 day period, regardless of whether such failure might be curable at
some time beyond such additional 30 day period, such failure shall nevertheless
be considered an Event of Default.

          9.4  DEFAULT ON OTHER OBLIGATIONS.  The occurrence of a material
default following the expiration of any applicable cure period, if any, in any
material obligation of the Company or any violation of law or refusal of
regulatory permission which has a material adverse effect on the Company's
operations.

          9.5  CERTAIN EVENTS AS TO THE COMPANY.  The Company shall (A) admit in
writing its inability to pay its debts generally as they become due; (B) file a
petition or answer or consent seeking relief under the Federal Bankruptcy Code,
as now constituted or hereafter amended, or any other applicable federal or
state bankruptcy or insolvency law or other similar law, not discharged or
vacated or set aside or stayed within 45 days; (C) consent to the institution of
proceedings under any law referenced in (B) above, not discharged or vacated or
set aside or stayed within 45 days, or to the filing of any such petition, not
discharged or vacated or set aside or stayed within 45 days or to the
appointment or taking possession of a receiver, liquidator, assignee, trustee,
custodian (or other similar official) of the Company or any subsidiary or of any
substantial part of their property; (D) fail generally to pay its debts as such
debts become due, or take corporate action in furtherance of any such action;
(E) make an assignment for the benefit of its creditors; or (F) fail to meet any
of its material monetary obligations; provided, however, that no Event of
Default shall be considered to have occurred under subsection 9.5(F) if the
failure to meet such material monetary obligations is due to a good faith
dispute between such parties, which dispute shall continue for no more than 30
days; provided further, that upon the expiration of such 30 day period, the
Company shall have, upon notice to the Investor an additional 30 day period to
resolve the dispute.  If the dispute is not resolved after the expiration of
such additional 30 day period, regardless whether such dispute may be resolved
at some time beyond such additional 30 day period, such failure under subsection
9.5(F) shall nevertheless be considered an Event of Default.

                                       25
<PAGE>
 
          9.6  CERTAIN EVENTS AS TO FRANK WILDE.  Frank Wilde dies, is disabled
for a period in excess of 120 days during which Mr. Wilde is unable to perform
his duties as an officer of the Company for a full eight hour day (the
"disability" of Mr. Wilde), terminates his employment with the Company or has
his employment terminated by the Company.

     10.  RIGHTS OF INVESTOR UPON DEFAULT.

          10.1 RIGHTS ON DEFAULT.  If there shall occur and be continuing an
Event of Default as defined in the foregoing Section 9, as long as the Debenture
is outstanding, the Investor may, by written notice to the Company, declare the
Company to be in default hereunder, whereupon, if the Investor so specifies in
such notice, the Debenture and all other indebtedness of the Company to the
Investor now or hereafter incurred, shall become immediately due and payable
without further demand, presentation or notice of any kind.

          10.2 ADDITIONAL RIGHTS.  The Investor shall have such additional
rights and remedies as are contained herein, in the Debenture, the Warrants, the
Class B Preferred Stock, or in any other documents and agreements delivered or
given in connection herewith, and all rights which it might have at law or
equity, all of which rights and remedies shall be cumulative.

     11.  LOCK-UP AGREEMENT.  In the event that the Company determines to effect
an underwritten initial public offering, the Investor agrees that, for a period
of 180 days following the effective date of any registration filed in connection
therewith, the Investor will not directly or indirectly sell, transfer or
otherwise dispose of, any shares of Class B Preferred Stock, any shares of
Common Stock, or any right to acquire shares of Common Stock owned by the
Investor without the prior written consent of the underwriter(s) of such initial
public offering.  The Company agrees to use its best efforts to cause such
underwriter not to unreasonably withhold such consent.

     12.  FURTHER ASSURANCE.  The Company and the Investor agree to execute and
deliver all such other instruments and take all such other actions as any party
may reasonably request from time to time after the date hereof and without
payment of further consideration, in order to effectuate the transactions

(the "Class B Preferred Stock Financing"), such stock to be designated as Class
B Convertible Preferred Stock of the Company (the "Class B Preferred Stock"),
the preferences, limitations and rights of which are currently being negotiated
but shall provide that the stock be convertible at the option of its holders,

nonassessable shares of the common stock of the Company, par value $.01 per
share (the "Common Stock"), on a share for share basis; and

     WHEREAS, the Company desires financing in the aggregate amount of
$2,500,000 (the "Bridge Financing") to be used for general corporate purposes,
including working capital, pending the closing of the Class B Preferred Stock
Financing; and

     WHEREAS, based on and subject to the terms and conditions of this
Agreement, the Investor is willing to provide a portion of the Bridge Financing
by acquiring from the Company, at an aggregate purchase price of $250,000, a

set forth in the Debenture, into either shares of Class B Preferred Stock or
shares of Common Stock, and warrants (the "Warrants") for the purchase of up to
47,833 shares of Common Stock.

     4.   REPRESENTATIONS AND WARRANTIES OF INVESTOR AND RESTRICTIONS ON
TRANSFER.

          4.1  REPRESENTATIONS AND WARRANTIES BY THE INVESTOR.  The Investor
represents and warrants to the Company as follows:

               (a) The Investor (i) is acquiring the Debenture and the Warrants
          and (ii) upon conversion of the Debenture or the Class B Preferred
          Stock, or upon exercise of the Warrants, will acquire the applicable
          Conversion Shares then issuable, for investment for its own accounts
          and not with a view to, or for resale in connection with, any
          distribution of the Securities.  The Investor understands that the
          Securities have not been registered under the Securities Act, or under
          any state securities or "Blue Sky" laws, and, as a result, are subject
          to substantial restrictions on transfer.  The Investor acknowledges
          that the Securities must be held indefinitely unless subsequently
          registered under the Securities Act and any applicable state
          securities or "Blue Sky" laws, or exemptions from registration under
          the Securities Act and such laws are available; provided, however,
          that by making the representations herein, the Investor does not agree
          to hold any of the Securities for any minimum or other specific term
          and reserves the right to dispose of the Securities at any time in
          accordance with or pursuant to a registration statement or an
          exemption from registration under the Securities Act and any
          applicable state securities or "Blue Sky" laws.

               (b) This Agreement has been duly executed and delivered by the
          Investor and constitutes a valid and legally binding obligation of the
          Investor, enforceable in accordance with its terms, subject, as to
          enforcement, to bankruptcy, insolvency, reorganization and other laws
          of general applicability relating to or affecting creditors rights and
          to general equity principles.

               (c) The Investor is an "accredited investor," as that term is
          defined in Rule 501(a) of Regulation D under the Securities Act.

                                      10
<PAGE>
 
               (d) The Investor is an "accredited investor" under the
          regulations under the Texas Securities Act of 1957 (the "Texas
          Securities Act") and, accordingly, the offer and sale of the
          Securities to the Investor is an exempt transaction pursuant to
          Section 5(T) of the Texas Securities Act.

          4.2  LEGENDS.  The Investor understands that the certificates or other
instruments representing the Debenture and the Warrants and, until such time as
the sale of the Conversion Shares have been registered under the Securities Act,
the stock certificates representing the Conversion Shares, except as set forth
below, shall bear a restrictive legend in substantially the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
          SECURITIES LAWS AND MAY NOT BE TRANSFERRED IN THE ABSENCE OF SUCH
          REGISTRATION OR AN EXEMPTION THEREFROM UNDER SUCH ACT AND SUCH LAWS.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped if, unless otherwise required by state securities laws, (i) such
Securities are registered for sale under the Securities Act, (ii) in connection
with a sale transaction, such holder provides the Company with an opinion of
counsel, in a form reasonably acceptable to the Company's counsel, to the effect
that a public sale, assignment or transfer of such Securities may be made
without registration under the Securities Act, or (iii) such holder provides the
Company with an opinion of counsel, in a form reasonably acceptable to the
Company's counsel that such Securities can be sold pursuant to Rule 144(k)
promulgated under the Securities Act (or a successor rule thereto) ("Rule 144").
The Investor acknowledges, covenants and agrees to sell the Securities
represented by a certificate(s) from which the legend has been removed, only
pursuant to (i) a registration statement effective under the Securities Act, or
(ii) advice of counsel that such sale is exempt from registration required by
Section 5 of the Securities Act.

     5.   CONTINUATION AND SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The
representations and warranties contained in Sections 3.3, 3.4 and 3.5 hereof
shall survive the consummation of the transactions provided for in the
Transaction Documents and shall not terminate.  All other representations and
warranties contained herein shall survive the consummation of the transactions
provided for in the Transaction Documents for a period beginning on the date
hereof up to and including the earlier of the conversion of all Class B
Preferred Stock held by the Investor into Common Stock or December 31, 1999;
provided, however, that such period shall not end prior to December 31, 1998.
No such representation or warranty shall be deemed to have been waived, affected
or impaired by any investigation made by any person or persons.

     6.   AFFIRMATIVE COVENANTS OF THE COMPANY.  The Company hereby covenants to
comply with the following affirmative covenants, unless waived by the Investor
(or Atlantic Coastal Ventures, L.P., in which case the Investor shall be deemed
to have also waived such covenant), as long as the Debenture remains
outstanding; provided, however, that in the event the Debenture is converted
into shares of Class B Preferred Stock, the Company shall provide to the

                                      11
<PAGE>
 
Investor all such information and rights as the Company provides to any other
holder of Class B Preferred Stock, whether pursuant to the Company's Articles of
Incorporation, as amended, contract or otherwise; and provided, further, that
the Company shall comply with Section 6.2, unless waived by the Investor (or
Atlantic Coastal Ventures, L.P., in which case the Investor shall be deemed to
have also waived such covenant), until the earlier of (i) such time as the
Investor owns no Debenture, no Warrants, no Class B Preferred Stock and fewer
than 100,000 shares of Common Stock or (ii) the closing of an underwritten
initial public offering of any of the Company's securities under the Securities
Act (or any successor statute), yielding gross proceeds to the Company of at
least $7,500,000.

          6.1  FINANCIAL STATEMENTS.  The Company shall furnish to the Investor
the following financial statements, reports and other documents, such financial
statements to be prepared in accordance with generally accepted accounting
principles consistently applied, certified by the Company's chief executive or
financial officer:

               (a) as soon as available, and in any event within 90 days after
          the end of each fiscal year of the Company, a balance sheet of the
          Company as of the end of such fiscal year and related statements of
          operations, shareholders' equity and cash flows for such fiscal year,
          all in reasonable detail and setting forth in comparative form the
          figures as of the end of and for the previous fiscal year, which
          financial statements shall have been audited, and shall be accompanied
          by an unqualified opinion addressed to the Company from "Big Six"
          independent auditors or other independent auditors that are reasonably
          satisfactory to the Investor, together with a copy of such auditors'
          letter to Company's management;

               (b) as soon as available, and in any event within 20 days after
          the end of each month for such month and for the year to date, an
          unaudited balance sheet and unaudited statements of operations,
          shareholders' equity and cash flows, together with a comparison of
          such financial statements with the budget of the Company for such
          period; and

               (c) as soon as available, and in any event at least 60 days prior
          to the end of each fiscal year of the Company, an annual budget and
          business plan for the subsequent fiscal year, which budget and
          business plan shall include a monthly breakdown of financial
          statements, which breakdown shall include the underlying assumptions
          and a brief qualitative description of the Company's plan by the
          Company's Chief Executive Officer in support of such budget and
          business plan, which also shall have been approved and accepted by the
          Board of Directors of the Company.  If during the course of operations
          for any such month it becomes apparent that deviations from such
          financial statements, budget and business plan have occurred, the
          Company shall submit to its Board of Directors a statement of such
          deviation within five business days from the date of the Company's
          knowledge of such deviation (the "Statement").  The Statement shall
          detail the manner in which a new financial projection deviates from
          the annual business plan and the reason therefor.  The Board of
          Directors shall have the right to ask questions or request any other
          reasonable additional information with respect to the Statement.  Any
          and all subsequent deviations from such financial

                                      12
<PAGE>
 
          statements shall be resubmitted to the Board of Directors of the
          Company for approval and acceptance or for required further revision
          until such approval and acceptance is obtained.

In the event that the Company at any time hereafter is required, by law or by
generally accepted accounting principles, to consolidate its financial
statements with those of a subsidiary corporation, the Company shall thereafter
finish the financial statements required by this Section 6.1 on a consolidated
basis, and the monthly and annual financial statements specified above shall be
furnished with consolidating financial statements.

          its capital stock except from employees upon termination of
          employment;

               (c) incur, create, assume or guarantee any indebtedness which
          ranks senior or pari passu in the right of payment to the Debenture,
          other than additional pari passu bridge financing of up to $750,000 on
          the same terms and considerations contemplated hereby, which the
          Company may obtain following the execution of this Agreement;

               (d) except as contemplated by this Agreement, amend the Articles
          of Incorporation or the By-laws; or

                                       15

               (e) effect any material change in the nature of the business of
          the Company, or apply the assets of the Company other than for the

          and proposed to be conducted.

          7.2  LIENS AND ENCUMBRANCES.  Except for Permitted Liens (as defined
in Section 3.20), the Company shall not create, assume, or permit to exist any

payable in cash or other property or make or authorize any other distribution,

          7.4  AGREEMENTS.  The Company shall not enter into any contract,
agreement, lease or other instrument which, by its terms, restricts, in any
material respect, the Company's ability to make payment on the Debenture, or
which otherwise restricts, in any material respect, the Company's ability to
perform under the Transaction Documents.

          7.5  INSIDER TRANSACTIONS.  Except as disclosed in Schedules 3.21 and
                                                             --------------

Directors of the Company has previously approved the execution of such contracts
or such contracts were explicitly included in an approved budget of the Company.
Notwithstanding the foregoing, the Company shall obtain the 

                                       16

     8.   REGISTRATION AND RELATED RIGHTS.
 
          8.1  PIGGYBACK REGISTRATION.

               (a)  As used in this Section 8, "Registration Stock" shall mean
          any Securities or any other shares of Common Stock, Class B Preferred
          Stock or other securities received by holders of the Securities upon
          any stock split, stock dividend, recapitalization, merger,
          consolidation or similar event; provided, however, that Registration
          Stock shall not include any Securities or such other securities
          disposed of pursuant to one or more registration statements under the
          Securities Act, or which have been sold pursuant to Rule 144 (as
          previously defined) or which have otherwise been sold without
          registration under the Securities Act. For purposes of this Section 8,
          any record holder of securities convertible into Registration Stock
          (or exercisable for or payable in Registration Stock) shall be deemed
          to be the holder of the Registration Stock issuable upon such
          conversion and/or exercise and/or payment.

               (b) If the Company should seek to register under the Securities
          Act or qualify any of the securities holdings of the Company or any of
          its shareholders (except in connection with any stock option plan,
          stock purchase plan, savings or similar plan or an acquisition, merger
          or exchange of stock, to be registered on Forms S-4, S-8 or any
          successor forms under the Securities Act) and if the form of
          registration statement proposed to be used otherwise may be used for
          the registration of the Registration Stock, then, on each such
          occasion, the Company shall furnish the Investor with at least 30 days
          prior written notice thereof. At the written request of the Investor,
          given within 20 days after the receipt of such notice, the Company
          will use its best efforts to cause all of the Registration Stock for
          which registration shall have been requested by the Investor to be
          included in such registration statement. In the event that the
          proposed registration by the Company is, in whole or in part, an
          underwritten public offering of securities of the Company, and the
          managing underwriter determines and advises in writing that the
          inclusion of all Registration Stock proposed to be included in the
          underwritten public offering and other issued and outstanding shares
          of Common Stock proposed to be included therein by persons other than
          (i) holders of Registration Stock or (ii) holders of Subordinate
          Shares (as defined in Section 8.4) with rights equal to those of the
          holders of Registration Stock ("Other Registration Stock") (such other
          shares which are not Registration Stock or Other Registration Stock
          being the "Other Shares") would interfere with the successful
          marketing (including pricing) of the securities, then the number of
          shares of Registration Stock, Other Registration Stock and Other
          Shares to be included in such underwritten public offering shall be
          reduced first, pro rata among the holders of Other Shares; second, if
          necessary, pro rata among the holders of Registration Stock and Other
          Registration Stock combined, based on the number of shares requested
          by holders thereof to be registered in such underwritten public

                                       17
<PAGE>
 
          offering; and lastly, if necessary, among the Company's shares
          requested by the Company to be registered; provided, however, that the
          holders of Registration Stock do not then elect to exercise their
          rights under Section 8.2; and, further provided, that in no event,
          without the consent of the holders of at least 67% of the Registration
          Stock, shall the percentage of the Registration Stock that is included
          in such registration statement be less than the percentage of the
          securities of any other shareholder included therein. In the event
          that the Company offers any of its securities in an offering exempt
          from registration under the Securities Act pursuant to Regulation A,
          the Company will provide to the holders of Registration Stock rights
          comparable to those provided herein.

          8.2  DEMAND REGISTRATION.

          (a) After the closing of an underwritten offering of the Common Stock,
     if at any time the Company is requested in writing by the holders of not
     less than 67% of the Registration Stock to effect the registration under
     the Securities Act of at least 33 1/3% of the Registration Stock, the
     Company shall promptly give written notice of such proposed registration to
     all record holders of Registration Stock.  Such holders shall have the
     right, by giving written notice to the Company within 30 days from receipt
     of the Company's notice, to elect to have included in such registration
     such of their Registration Stock as such holders may request in such notice
     of election.  Thereupon, the Company shall, as expeditiously as possible,
     use its best efforts to effect the registration, on a form of general use
     under the Securities Act, of all shares of Registration Stock which the
     Company has been requested to register; provided, however, that if the
     holders of not less than 67% of the Registration Stock shall so request
     (and at least 50% of the Registration Stock is being registered), the
     Company shall file such registration statement pursuant to Rule 415 or any
     successor rule or regulation under the Securities Act so as to permit the
     continuous or delayed offering of the Registration Stock in accordance with
     the intended method of disposition specified in the notice of the exercise
     of rights under this Section 8.2(a), to the extent such offering qualifies
     under such rule or regulation, but in no event shall the Company be
     required to maintain the effectiveness of such registration statement
     beyond a two year period.  The Company shall be obligated to cause to
     become effective one registration statement pursuant to which Registration
     Stock is sold under this Section 8.2(a).

          (b) In addition and not in limitation of the rights set forth in
     Sections 8.1(b) and 8.2(a), at such time as the Company shall have
     qualified for the use of a short form Form S-3 in an offering solely for
     the accounts of persons other than the Company (or any similar form or
     forms promulgated by the Securities and Exchange Commission), the holders
     of not less than 67% of the Registration Stock shall have the right to
     request an unlimited number of registrations on Form S-3 or other similar
     forms.  Holders shall have the right, by giving written notice to the
     Company within 20 days from receipt of notice from the Company of such
     request, to elect to have included in such registration such of their
     Registration Stock as such holders may request in such notice of election.
     Thereupon, the 

                                       18
<PAGE>
 
     Company shall, as expeditiously as possible, use its best efforts to effect
     the registration, on Form S-3 of all shares of Registration Stock which the
     Company has been requested to register. The Company shall not be required
     to effect any such registration more than once every twelve months.
     Registrations effected on Form S-3 shall not be considered to be demand
     registrations pursuant to Section 8.2(a) hereof.

          (c) The Company may include in a registration requested under this
     Section 8.2 any additional authorized shares of the Common Stock of the
     Company, whether or not issued, for sale by the Company or for sale by
     others; provided, however, that such shares shall not be included to the
     extent that the holders of a majority of the shares of Registration Stock
     included therein determine in good faith that the inclusion of such shares
     will interfere with the successful marketing of the shares of Registration
     Stock to be included therein; and, provided, further, that, upon the
     election of the holders of a majority of the shares of Registration Stock
     included therein, or if the number of shares to be so included equals or
     exceeds the number of shares of Registration Stock included therein by the
     holders of Registration Stock, such registration shall be deemed to be a
     registration pursuant to Section 8.1(b) hereof.

          (d) The underwriter and the terms of the underwriting for any
     registration pursuant to this Section 8.2 shall be mutually acceptable to
     the Company and the Investor.

          (e) Notwithstanding anything contained in this Agreement to the
     contrary:

               (i) The Company reserves the right to delay any such registration
          pursuant to Section 8 for a period of not more than sixty days, or to
          withhold efforts to cause such registration statement to become
          effective for a period of not more than sixty days, if the Board of
          Directors of the Company determines in good faith that such
          registration might (A) interfere with or affect the negotiation or
          completion of any material transaction that is being contemplated by
          the Company, or (B) involve initial or continuing disclosure
          obligations materially adverse to the best interests of the Company's
          shareholders.  If, after a registration statement becomes effective,
          the Company advises the holders of the Registration Stock covered by
          such registration statement that the Company considers it appropriate
          for the registration statement to be amended, the holders of such
          shares shall suspend any further sales of their registered shares
          until the Company advises them that the registration statement has
          been amended.  The time periods referred to in this Section 8 shall be
          extended for an additional number of business days during which the
          rights to sell shares was suspended.

               (ii) The Company shall not be obligated to file a registration
          statement pursuant to Section 8.2 within three months after the
          effective 

                                       19
<PAGE>
 
          date of any registration under which piggyback rights were granted
          pursuant to Section 8.1.

     8.3  FURTHER OBLIGATIONS OF THE COMPANY.  Whenever the Company is
required to register any of the Registration Stock pursuant to any of the
provisions of this Section 8, the Company shall also be obligated to:

          (a) prepare for filing and file with the Securities and Exchange
     Commission promptly thereafter a registration statement and such
     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 (but, other than as otherwise provided in Section 8.2(a), in
     no event more than nine months) to complete the proposed public
     offering;

          (b) furnish to each selling holder so requesting such copies of
     preliminary and final prospectus and such other documents as said holder
     may reasonably request to facilitate the public offering of such holder's
     Registration Stock;

          (c) use its best efforts to register or qualify the Registration Stock
     covered by said registration statement under the securities or "Blue Sky"
     laws of such jurisdictions as the holders of Registration Stock may
     reasonably request, to keep such registration or qualification in effect
     for so long as such registration statement remains in effect, and do any
     and all other acts and things that may be reasonably necessary or advisable
     to enable such seller to consummate the disposition in such jurisdictions
     of its Registration Stock covered by such registration statement, except
     that the Company shall not for any such purpose be required to qualify
     generally to do business as a foreign corporation in any jurisdiction
     wherein it would not, but for the requirements of this subdivision (c), be
     obligated to be so qualified, or to subject itself to taxation in any such
     jurisdiction, or to consent to general service of process in any such
     jurisdiction;

          (d) furnish to the selling holders, and any underwriters or broker-
     dealers through whom the Registration Stock may be sold, an opinion or
     opinions of counsel for the Company and a "cold comfort" letter or letters
     of the independent auditors for the Company, in form and substance
     customary for similar offerings;

          (e) permit each selling holder or the selling holder's counsel or
     other representatives, at the selling holder's expense, to inspect and copy
     such corporate documents and records as may reasonably be requested by
     them;

           (f) if so requested, furnish to each selling holder a copy of all
     documents filed and all correspondence to or from the Securities and
     Exchange Commission in connection with any such offering;

                                       20
<PAGE>
 
          (g) immediately notify each seller of Registration Stock covered by
     such registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the Securities Act, upon discovery that,
     or upon the happening of any event as a result of which, the prospectus
     included in such registration statement, as then in effect, includes an
     untrue statement of a material fact or omits to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading in the light of the circumstances then existing, and at the
     request of any such seller or holder, prepare and furnish to such seller
     and holder a reasonable number of copies of a supplement to or an amendment
     of such prospectus as may be necessary so that, as thereafter delivered to
     the purchasers of such Registration Stock, such prospectus shall not
     include an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances then existing;

          (h) otherwise use its best efforts to comply with all applicable rules
     and regulations of the Securities and Exchange Commission, and make
     available to its security holders, as soon as reasonably practicable, an
     earnings statement covering a period of at least twelve months, but not
     more than eighteen months, beginning with the first month of the first
     fiscal quarter after the effective date of such registration statement,
     which earnings statement shall satisfy the provisions of Section 13(a) of
     the Securities Exchange Act of 1934, as amended (the "Exchange Act"); and

          (i) provide and cause to be maintained a transfer agent and registrar
     for all registrable securities covered by such registration statement from
     and after a date not later than the effective date of such registration
     statement.

If requested by the Company, each seller of Registration Stock as to which any
registration is being effected shall furnish the Company with such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing as shall be required by law or
by the Securities and Exchange Commission in connection therewith.

          8.4  REGISTRATION RIGHTS EQUAL OR SUPERIOR.  The Company shall not
grant any registration rights or register any securities for the account of any
person other than holders of Registration Stock unless permitted to do so by the
written consent of the holders of not less than 67% of the Registration Stock
(such securities being the "Subordinate Shares").

          8.5  EXPENSES, ETC.  All expenses in connection with the preparation
and filing of any registration statement under this Section 8, any registration
or qualification under the securities or "Blue Sky" laws of states in which the
offering will be made under such registration statement, and any filing fee of
the National Association of Securities Dealers, Inc. relating to such offering,
shall be borne in full by the Company, except for any (i) underwriters' or
brokers' commissions applicable to the shares to be sold by a holder of
Registration Stock, (ii) fees required to be paid by a selling shareholder
rather than the Company in order to comply with "Blue Sky" or state securities
laws, (iii) other fees or expenses expressly applicable to securities 

                                       21
<PAGE>
 
being sold by the selling shareholder, and (iv) fees or expenses of any selling
shareholders' counsel.

          8.6  INDEMNIFICATION.  The Company shall indemnify the selling holders
of Registration Stock, and, to the extent required in any agreement with any
underwriter or broker-dealer through whom the Registration Stock may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities, expenses or actions in respect
thereof (under the Securities Act or common law or otherwise) caused by any
untrue statement or alleged untrue statement of a material fact contained in any
registration statement under which such Registration Stock was registered under
the Securities Act, any preliminary or final prospectus contained therein, or
any amendment or supplement thereto (unless cured by an amendment or supplement
to the prospectus delivered to the selling holders prior to the sales of the
Registration Stock that is subject to the claimed right of indemnification), or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registration Stock
that is subject to the claimed right of indemnification); and will reimburse the
selling holders of Registration Stock for any legal or other out-of-pocket
expenses reasonably incurred by such selling holders in connection with
investigating or defending against such loss, claim, damage, liability or
action; except insofar as such losses, claims, damages, liabilities or expenses
are caused by any untrue statement or omission contained in information
furnished in writing to the Company by such selling holders expressly for use
therein.  In connection with any such registration statement, the selling
holders of Registration Stock will furnish the Company in writing such
information as may reasonably be requested by the Company for use in any such
registration statement or prospectus and will indemnify the Company, its
directors and officers, and, to the extent required in any agreement with any
underwriter or broker-dealer, each such underwriter or broker-dealer and each
person, if any, who controls the Company or any underwriter or broker-dealer
(within the meaning of the Securities Act) against any losses, claims, damages,
liabilities, expenses and actions in respect thereof (under the Securities Act
or common law or otherwise) caused by any untrue statement or alleged untrue
statement of a material fact required to be stated in such registration
statement or prospectus and necessary to make the statements therein not
misleading; and will reimburse the Company for any legal or other out-of-pocket
expenses reasonably incurred by it in connection with investigating or defending
against such loss, claim, damage, liability or action; but only to the extent
that such untrue statement or omission was contained in information so furnished
in writing by the selling holders of Registration Stock expressly for use
therein, and only to the extent of proceeds received by the selling holders of
Registration Stock in the offering.  The Company further agrees and the selling
shareholders shall agree that, in connection with any underwritten public
offering, the Company also will enter into customary contribution arrangements
with the selling holders of Registration Stock and the underwriters or broker-
dealers through whom the Registration Stock may be sold, with respect to
situations in which indemnification is potentially unavailable.

          8.7  WITHDRAWAL.  If a public offering is not completed within nine
months after the effective date of any registration statement filed by the
Company pursuant to Section 8.1(b), other than an offering under Rule 415 as
described in Section 8.2(a), the Company 

                                       22
<PAGE>
 
reserves the right, at its option, to withdraw from registration any securities
offered by the Company which have not been sold during such period, provided
that no securities offered by any holder of Registration Stock shall be
withdrawn without the consent of the holders of 50% of the Registration Stock.

          8.8  EXCHANGE ACT.  As promptly as possible following receipt of a
written request therefor from the holders of 50% of the outstanding Registration
Stock at any time while the Company either (a) is subject to periodic reporting
pursuant to Section 15(d) of the Exchange Act or (b) has 300 or more
shareholders of record, the Company shall register its Common Stock under
Section 12 of the Exchange Act, arrange for its Common Stock to be listed on a
national stock exchange or included for quotation on the Nasdaq National Market,
as requested, and shall keep effective such registration and maintain such
listing or inclusion, and shall use its best efforts timely to file such
information, documents and reports as the Securities and Exchange Commission may
require or prescribe that the Company file in connection therewith.  The Company
will, at the request of any holder of Registration Stock, advise such holder in
writing as to whether all reports required to be filed by the Company under
Section 13 of the Exchange Act during the 12 months preceding such request (or
for such shorter period as the Company was required to file such reports) have
been filed, and any other information which the holder may reasonably require in
order to comply with Rule 144, or any other comparable rule, as then in effect.

     9.   EVENTS OF DEFAULT.

     Each of the following shall constitute an Event of Default under this
     Agreement:

          9.1  DEFAULT ON PAYMENTS TO THE INVESTOR.  The failure of the Company
to make (a) any principal or interest payment on the Debenture when due, or (b)
any other payment upon any other written obligation of the Company to the
Investor within 15 days after written notice from the Investor to the Company;
regardless of whether any such failure to make the payments described in (a) and
(b) above is due to a legal inability or the incapacity of the Company to make
any such payments.

          9.2  INFORMATION, REPRESENTATIONS AND WARRANTIES.  Any information
furnished or representation or warranty made or given by the Company herein
shall prove to have been untrue when made or given in any material respect or
shall have omitted to state a material fact respecting the matters set forth
therein necessary to make the matters set forth therein not misleading.

          9.3  COVENANTS AND AGREEMENTS.  The failure of the Company to observe,
perform or abide by any other covenant, warranty, agreement or provision in any
of the Transaction Documents, which failure is not cured to the Investor's
reasonable satisfaction within 30 days after written notice from the Investor to
the Company of its occurrence; provided, however, that no Event of Default shall
be considered to have occurred if the failure is not the failure to pay money
and is of such a nature that it reasonably cannot be cured within the Cure
Period, but if it is curable and the Company in good faith begins efforts to
cure it within the Cure Period and continues diligently to do so, the Company
shall have an additional 30 days from the date on which the Cure Period ends to
effect the cure.  If the failure continues  after the expiration 

                                       23
<PAGE>
 
of such additional 30 day period, regardless of whether such failure might be
curable at some time beyond such additional 30 day period, such failure shall
nevertheless be considered an Event of Default.

          9.4  DEFAULT ON OTHER OBLIGATIONS.  The occurrence of a material
default following the expiration of any applicable cure period, if any, in any
material obligation of the Company or any violation of law or refusal of
regulatory permission which has a material adverse effect on the Company's
operations.

          9.5  CERTAIN EVENTS AS TO THE COMPANY.  The Company shall (A) admit in
writing its inability to pay its debts generally as they become due; (B) file a
petition or answer or consent seeking relief under the Federal Bankruptcy Code,
as now constituted or hereafter amended, or any other applicable federal or
state bankruptcy or insolvency law or other similar law, not discharged or
vacated or set aside or stayed within 45 days; (C) consent to the institution of
proceedings under any law referenced in (B) above, not discharged or vacated or
set aside or stayed within 45 days, or to the filing of any such petition, not
discharged or vacated or set aside or stayed within 45 days or to the
appointment or taking possession of a receiver, liquidator, assignee, trustee,
custodian (or other similar official) of the Company or any subsidiary or of any
substantial part of their property; (D) fail generally to pay its debts as such
debts become due, or take corporate action in furtherance of any such action;
(E) make an assignment for the benefit of its creditors; or (F) fail to meet any
of its material monetary obligations; provided, however, that no Event of
Default shall be considered to have occurred under subsection 9.5(F) if the
failure to meet such material monetary obligations is due to a good faith
dispute between such parties, which dispute shall continue for no more than  30
days; provided; further, that upon the expiration of such 30 day period, the
Company shall have, upon notice to the Investor an additional 30 day period to
resolve the dispute.  If the dispute is not resolved after the expiration of
such additional 30 day period, regardless whether such dispute may be resolved
at some time beyond such additional 30 day period, such failure under subsection
9.5(F) shall nevertheless be considered an Event of Default.

     10.  RIGHTS OF INVESTOR UPON DEFAULT.

          10.1 RIGHTS ON DEFAULT.  If there shall occur and be continuing an
Event of Default as defined in the foregoing Section 9, as long as the Debenture

the sale of the Conversion Shares have been registered under the Securities Act,
the stock certificates representing the Conversion Shares, except as set forth
below, shall bear a restrictive legend in substantially the following form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT
          BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
          AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE
          TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
          EXEMPTION THEREFROM UNDER SUCH ACT AND SUCH LAWS.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped if, unless otherwise required by state securities laws, (i) such
Securities are registered for sale under the Securities Act, (ii) in connection
with a sale transaction, such holder provides the Company with an opinion of
counsel, in a form reasonably acceptable to the Company's counsel, to the effect
that a public sale, assignment or transfer of such Securities may be made
without registration under the Securities Act, or (iii) such holder provides the
Company with an opinion of counsel, in a form reasonably acceptable to the
Company's counsel, that such Securities can be sold pursuant to Rule 144(k)
promulgated under the Securities Act (or a successor rule thereto) ("Rule 144").
The Investor acknowledges, covenants and agrees to sell the Securities
represented by a certificate(s) from which the legend has been removed, only
pursuant to (i) a registration statement effective under the Securities Act, or
(ii) advice of counsel that such sale is exempt from registration required by
Section 5 of the Securities Act.

     5.   CONTINUATION AND SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The
representations and warranties contained in Sections 3.3, 3.4 and 3.5 hereof
shall survive the consummation of the transactions provided for in the
Transaction Documents and shall not terminate.  All other representations and
warranties contained herein shall survive the consummation of the transactions
provided for in the Transaction Documents for a period beginning on the date
hereof up to and including the earlier of the conversion of all Class B
Preferred Stock held by the Investor into Common Stock or December 31, 1999;
provided, however, that such period shall not end prior to December 31, 1998.
No such representation or 

                                       11

warranty shall be deemed to have been waived, affected or impaired by any
investigation made by any person or persons.

     6.   AFFIRMATIVE COVENANTS OF THE COMPANY.  The Company hereby covenants to
comply with the following affirmative covenants, unless waived by the Investor
(or Atlantic Coastal Ventures, L.P., in which case the Investor shall be deemed
to have also waived such covenant), as long as the Debenture remains
outstanding; provided, however, that in the event the Debenture is converted
into shares of Class B Preferred Stock, the Company shall provide to the
Investor all such information and rights as the Company provides to any other
holder of Class B Preferred Stock, whether pursuant to the Company's Articles of
Incorporation, as amended, contract or otherwise; and provided, further, that
the Company shall comply with Section 6.2, unless waived by the Investor (or
Atlantic Coastal Ventures, L.P., in which case the Investor shall be deemed to
have also waived such covenant), until the earlier of (i) such time as the
Investor owns no Debentures, no Warrants, no Class B Preferred Stock and fewer
than 100,000 shares of Common Stock or (ii) the closing of an underwritten
initial public offering of any of the Company's securities under the Securities
Act (or any successor statute), yielding gross proceeds to the Company of at
least $7,500,000.

          6.1  FINANCIAL STATEMENTS.  The Company shall furnish to the Investor
the following financial statements, reports and other documents, such financial
statements to be prepared in accordance with generally accepted accounting
principles consistently applied, certified by the Company's chief executive or
financial officer:

               (a) as soon as available, and in any event within 90 days after
          the end of each fiscal year of the Company, a balance sheet of the
          Company as of the end of such fiscal year and related statements of
          operations, shareholders' equity and cash flows for such fiscal year,
          all in reasonable detail and setting forth in comparative form the
          figures as of the end of and for the previous fiscal year, which
          financial statements shall have been audited, and shall be accompanied
          by an unqualified opinion addressed to the Company from "Big Six"
          independent auditors or other independent auditors that are reasonably
          satisfactory to the Investor, together with a copy of such auditors'
          letter to Company's management;

               (b) as soon as available, and in any event within 20 days after
          the end of each month for such month and for the year to date, an
          unaudited balance sheet and unaudited statements of operations,
          shareholders' equity and cash flows, together with a comparison of
          such financial statements with the budget of the Company for such
          period; and

               (c) as soon as available, and in any event at least 60 days prior
          to the end of each fiscal year of the Company, an annual budget and
          business plan for the subsequent fiscal year, which budget and
          business plan shall include a monthly breakdown of financial
          statements, which breakdown shall include the underlying assumptions
          and a brief qualitative description of the Company's plan by the
          Company's Chief Executive Officer in support of such budget and
          business plan, which also 

                                       12
<PAGE>
 
          shall have been approved and accepted by the Board of Directors of the
          Company. If during the course of operations for any such month it
          becomes apparent that deviations from such financial statements,
          budget and business plan have occurred, the Company shall submit to
          its Board of Directors a statement of such deviation within five
          business days from the date of the Company's knowledge of such
          deviation (the "Statement"). The Statement shall detail the manner in
          which a new financial projection deviates from the annual business
          plan and the reason therefor. The Board of Directors shall have the
          right to ask questions or request any other reasonable additional
          information with respect to the Statement. Any and all subsequent
          deviations from such financial statements shall be resubmitted to the
          Board of Directors of the Company for approval and acceptance or for
          required further revision until such approval and acceptance is
          obtained.

In the event that the Company at any time hereafter is required, by law or by
generally accepted accounting principles, to consolidate its financial
statements with those of a subsidiary corporation, the Company shall thereafter
finish the financial statements required by this Section 6.1 on a consolidated
basis, and the monthly and annual financial statements specified above shall be
furnished with consolidating financial statements.

          6.2  ADDITIONAL INFORMATION.

               (a) The Company shall, as promptly as possible (but, in any event
          within ten days) after obtaining knowledge of the occurrence of any

          other material adverse development or event, furnish the Investor with
          a detailed written notice of such default or event and the proposed
          response of Company management.

          of the confidential information.  The term "confidential information"
          does not include information which (i) was or becomes generally
          available to the public other than as a result of a disclosure by the
          Investor, or (ii) was or becomes available to the Investor on a
          nonconfidential basis from a source other than the Company, provided
          that such source is not bound by a confidentiality agreement with the
          Company.

          6.3  INSPECTION.  The Company shall permit, at any reasonable time and
from time to time upon reasonable advance notice, the Investor or its duly
authorized agents or representatives to examine and make copies of, and extracts

Company shall maintain complete and exclusive ownership of, but shall have the
right to license or sublicense, its patents, trademarks, trade names, service
marks, and other proprietary rights.

its transactions, and shall devise and maintain a system of internal accounting
controls sufficient to provide reasonable 

                                       14

assurances that: (a) transactions are executed in accordance with management's
general or specific authorization; (b) transactions are recorded as necessary to
permit preparation of the financial statements required herein and to maintain
accountability for assets; and (c) access to assets is permitted only in
accordance with management's general or specific instructions and recorded

          6.7  OTHER INSURANCE.  The Company shall maintain insurance against

material respects with the provisions of all material contracts, indentures,
instruments and agreements to which it is a party or by which the Company or its

state, local, and foreign taxes, assessments, penalties, interest and
governmental charges which become payable by the Company or which shall be
imposed upon its properties, and all claims for labor, materials or supplies
which if unpaid might by law become a lien upon any of its properties; provided,
however, that the Company may in good faith contest any tax, assessment,
penalty, or charge, provided that such contest is asserted in accordance with
applicable procedures.

          6.10 COMPLIANCE WITH LAWS.  The Company shall comply with all laws,

Debenture remains outstanding the Company shall comply with the following
negative covenants unless such covenant is waived by the Investor; provided,
however, that a waiver of any covenant or the approval of any action hereunder
by Atlantic Coastal Ventures, L.P. ("Atlantic") shall be deemed to constitute a
waiver of such covenant or approval of such action by the Investor.

          7.1  CONDUCT OF BUSINESS.  The Company shall not:

               (a) (i) merge or consolidate with or into, or permit any

                                       15

          cash portion of the purchase price not to exceed $2,500,000
          (excluding any applicable taxes that the Company has agreed to
          assume);

               (b) except as otherwise required, permitted or acknowledged
          by this Agreement or any Schedule hereto, create, authorize or

          acquire any shares of capital stock or any other security, or
          repurchase any shares of its capital stock except from employees
          upon termination of employment;

               (c) incur, create, assume or guarantee any indebtedness
          which ranks senior or pari passu in the right of payment to the

          the conduct of the business of the Company, as such business is
          conducted and proposed to be conducted.

          7.2  LIENS AND ENCUMBRANCES.  Except for Permitted Liens (as defined
in Section 3.20), the Company shall not create, assume, or permit to exist any
lien, security interest, pledge or other encumbrance, under conditional or

assets, whether tangible or intangible, now owned or hereafter acquired, except
for liens for current taxes not delinquent.

          7.3  DIVIDENDS.  The Company shall not declare or pay any dividend

3.22, the Company shall not enter into any transaction with any of its officers,
- ----

Notwithstanding the foregoing, the Company shall obtain the prior written
approval of the Investor with respect to any material contracts submitted to

     8.   REGISTRATION AND RELATED RIGHTS.

          8.1  PIGGYBACK REGISTRATION.

               (a) As used in this Section 8, "Registration Stock" shall
          mean any Securities or any other shares of Common Stock, Class B
          Preferred Stock or other securities received by holders of the
          Securities upon any stock split, stock dividend,
          recapitalization, merger, consolidation or similar event;
          provided, however, that Registration Stock shall not include any
          Securities or such other securities disposed of pursuant to one
          or more registration statements under the Securities Act, or
          which have been sold pursuant to Rule 144 (as previously defined)
          or which have otherwise been sold without registration under the
          Securities Act. For purposes of this Section 8, any record holder
          of securities convertible into Registration Stock (or exercisable
          for or payable in Registration Stock) shall be deemed to be the
          holder of the Registration Stock issuable upon such conversion
          and/or exercise and/or payment.

               (b) If the Company should seek to register under the
          Securities Act or qualify any of the securities holdings of the
          Company or any of its shareholders (except in connection with any
          stock option plan, stock purchase plan, savings or similar plan
          or an acquisition, merger or exchange of stock, to be registered
          on Forms S-4, S-8 or any successor forms under the Securities
          Act) and if the form of registration statement proposed to be
          used otherwise may be used for the registration of the
          Registration Stock, then, on each such occasion, the Company
          shall furnish the Investor with at least 30 days prior written
          notice thereof. At the written request of the Investor, given
          within 20 days after the receipt of

                                       17
<PAGE>
 
          such notice, the Company will use its best efforts to cause all
          of the Registration Stock for which registration shall have been
          requested by the Investor to be included in such registration
          statement. In the event that the proposed registration by the
          Company is, in whole or in part, an underwritten public offering
          of securities of the Company, and the managing underwriter
          determines and advises in writing that the inclusion of all
          Registration Stock proposed to be included in the underwritten
          public offering and other issued and outstanding shares of Common
          Stock proposed to be included therein by persons other than (i)
          holders of Registration Stock or (ii) holders of Subordinate
          Shares (as defined in Section 8.4) with rights equal to those of
          the holders of Registration Stock ("Other Registration Stock")
          (such other shares which are not Registration Stock or Other
          Registration Stock being the "Other Shares") would interfere with
          the successful marketing (including pricing) of the securities,
          then the number of shares of Registration Stock, Other
          Registration Stock and Other Shares to be included in such
          underwritten public offering shall be reduced first, pro rata
          among the holders of Other Shares; second, if necessary, pro rata
          among the holders of Registration Stock and Other Registration
          Stock combined, based on the number of shares requested by
          holders thereof to be registered in such underwritten public
          offering; and lastly, if necessary, among the Company's shares
          requested by the Company to be registered; provided, however,
          that the holders of Registration Stock do not then elect to
          exercise their rights under Section 8.2; and, further provided,
          that in no event, without the consent of the holders of at least
          67% of the Registration Stock, shall the percentage of the
          Registration Stock that is included in such registration
          statement be less than the percentage of the securities of any
          other shareholder included therein. In the event that the Company
          offers any of its securities in an offering exempt from
          registration under the Securities Act pursuant to Regulation A,
          the Company will provide to the holders of Registration Stock
          rights comparable to those provided herein.

          8.2  DEMAND REGISTRATION.

               (a) After the closing of an underwritten offering of the
          Common Stock, if at any time the Company is requested in writing
          by the holders of not less than 67% of the Registration Stock to
          effect the registration under the Securities Act of at least 33
          1/3% of the Registration Stock, the Company shall promptly give
          written notice of such proposed registration to all record
          holders of Registration Stock. Such holders shall have the right,
          by giving written notice to the Company within 30 days from
          receipt of the Company's notice, to elect to have included in
          such registration such of their Registration Stock as such
          holders may request in such notice of election. Thereupon, the
          Company shall, as expeditiously as possible, use its best efforts
          to effect the registration, on a form of general use under the
          Securities Act, of all shares of Registration Stock which the
          Company has been requested to register; provided, however,

                                       18
<PAGE>
 
          that if the holders of not less than 67% of the Registration
          Stock shall so request (and at least 50% of the Registration
          Stock is being registered), the Company shall file such
          registration statement pursuant to Rule 415 or any successor rule
          or regulation under the Securities Act, so as to permit the
          continuous or delayed offering of the Registration Stock in
          accordance with the intended method of disposition specified in
          the notice of the exercise of rights under this Section 8.2(a),
          to the extent such offering qualifies under such rule or
          regulation, but in no event shall the Company be required to
          maintain the effectiveness of such registration statement beyond
          a two year period. The Company shall be obligated to cause to
          become effective one registration statement pursuant to which
          Registration Stock is sold under this Section 8.2(a).

               (b) In addition and not in limitation of the rights set
          forth in Sections 8.1(b) and 8.2(a), at such time as the Company
          shall have qualified for the use of a short form Form S-3 in an
          offering solely for the accounts of persons other than the
          Company (or any similar form or forms promulgated by the
          Securities and Exchange Commission), the holders of not less than
          67% of the Registration Stock shall have the right to request an
          unlimited number of registrations on Form S-3 or other similar
          forms. Holders shall have the right, by giving written notice to
          the Company within 20 days from receipt of notice from the
          Company of such request, to elect to have included in such
          registration such of their Registration Stock as such holders may
          request in such notice of election. Thereupon, the Company shall,
          as expeditiously as possible, use its best efforts to effect the
          registration, on Form S-3 of all shares of Registration Stock
          which the Company has been requested to register. The Company
          shall not be required to effect any such registration more than
          once every twelve months. Registrations effected on Form S-3
          shall not be considered to be demand registrations pursuant to
          Section 8.2(a) hereof.

               (c) The Company may include in a registration requested
          under this Section 8.2 any additional authorized shares of the
          Common Stock of the Company, whether or not issued, for sale by
          the Company or for sale by others; provided, however, that such
          shares shall not be included to the extent that the holders of a
          majority of the shares of Registration Stock included therein
          determine in good faith that the inclusion of such shares will
          interfere with the successful marketing of the shares of
          Registration Stock to be included therein; and, provided,
          further, that, upon the election of the holders of a majority of
          the shares of Registration Stock included therein, or if the
          number of shares to be so included equals or exceeds the number
          of shares of Registration Stock included therein by the holders
          of Registration Stock, such registration shall be deemed to be a
          registration pursuant to Section 8.1(b) hereof.

                                       19

               (d) The underwriter and the terms of the underwriting for
          any registration pursuant to this Section 8.2 shall be mutually
          acceptable to the Company and the Investor.

               (e) Notwithstanding anything contained in this Agreement to
          the contrary:

                   (i)  The Company reserves the right to delay any such
               registration pursuant to Section 8 for a period of not more
               than sixty days, or to withhold efforts to cause such
               registration statement to become effective for a period of
               not more than sixty days, if the Board of Directors of the
               Company determines in good faith that such registration
               might (A) interfere with or affect the negotiation or
               completion of any material transaction that is being
               contemplated by the Company, or (B) involve initial or
               continuing disclosure obligations materially adverse to the
               best interests of the Company's shareholders. If, after a
               registration statement becomes effective, the Company
               advises the holders of the Registration Stock covered by
               such registration statement that the Company considers it
               appropriate for the registration statement to be amended,
               the holders of such shares shall suspend any further sales
               of their registered shares until the Company advises them
               that the registration statement has been amended. The time
               periods referred to in this Section 8 shall be extended for
               an additional number of business days during which the
               rights to sell shares was suspended.

                   (ii) The Company shall not be obligated to file a
               registration statement pursuant to Section 8.2 within three
               months after the effective date of any registration under
               which piggyback rights were granted pursuant to Section 8.1.

          8.3  FURTHER OBLIGATIONS OF THE COMPANY. Whenever the Company is
required to register any of the Registration Stock pursuant to any of the
provisions of this Section 8, the Company shall also be obligated to:

               (a) prepare for filing and file with the Securities and
          Exchange Commission promptly thereafter a registration statement
          and such 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 (but, other than as otherwise provided in
          Section 8.2(a), in no event more than nine months) to complete
          the proposed public offering;

                                       20
<PAGE>
 
               (b) furnish to each selling holder so requesting such copies
          of preliminary and final prospectus and such other documents as
          said holder may reasonably request to facilitate the public
          offering of such holder's Registration Stock;

               (c) use its best efforts to register or qualify the
          Registration Stock covered by said registration statement under
          the securities or "Blue Sky" laws of such jurisdictions as the
          holders of Registration Stock may reasonably request, to keep
          such registration or qualification in effect for so long as such
          registration statement remains in effect, and do any and all
          other acts and things that may be reasonably necessary or
          advisable to enable such seller to consummate the disposition in
          such jurisdictions of its Registration Stock covered by such
          registration statement, except that the Company shall not for any
          such purpose be required to qualify generally to do business as a
          foreign corporation in any jurisdiction wherein it would not, but
          for the requirements of this subdivision (c), be obligated to be
          so qualified, or to subject itself to taxation in any such
          jurisdiction, or to consent to general service of process in any
          such jurisdiction;

               (d) furnish to the selling holders, and any underwriters or
          broker-dealers through whom the Registration Stock may be sold,
          an opinion or opinions of counsel for the Company and a "cold
          comfort" letter or letters of the independent auditors for the
          Company, in form and substance customary for similar offerings;

               (e) permit each selling holder or the selling holder's
          counsel or other representatives, at the selling holder's
          expense, to inspect and copy such corporate documents and records
          as may reasonably be requested by them;

               (f) if so requested, furnish to each selling holder a copy
          of all documents filed and all correspondence to or from the
          Securities and Exchange Commission in connection with any such
          offering;

               (g) immediately notify each seller of Registration Stock
          covered by such registration statement, at any time when a
          prospectus relating thereto is required to be delivered under the
          Securities Act, upon discovery that, or upon the happening of any
          event as a result of which, the prospectus included in such
          registration statement, as then in effect, includes an untrue
          statement of a material fact or omits to state any material fact
          required to be stated therein or necessary to make the statements
          therein not misleading in the light of the circumstances then
          existing, and at the request of any such seller or holder,
          prepare and furnish to such seller and holder a reasonable number
          of copies of a supplement to or an amendment of such prospectus
          as may be necessary so that, as thereafter delivered to the
          purchasers of such Registration

                                       21
<PAGE>
 
          Stock, such prospectus shall not include an untrue statement of a
          material fact or omit to state a material fact required to be
          stated therein or necessary to make the statements therein not
          misleading in the light of the circumstances then existing;

               (h) otherwise use its best efforts to comply with all
          applicable rules and regulations of the Securities and Exchange
          Commission, and make available to its security holders, as soon
          as reasonably practicable, an earnings statement covering a
          period of at least twelve months, but not more than eighteen
          months, beginning with the first month of the first fiscal
          quarter after the effective date of such registration statement,
          which earnings statement shall satisfy the provisions of Section
          13(a) of the Securities Exchange Act of 1934, as amended (the
          "Exchange Act"); and

               (i) provide and cause to be maintained a transfer agent and
          registrar for all registrable securities covered by such
          registration statement from and after a date not later than the
          effective date of such registration statement.

If requested by the Company, each seller of Registration Stock as to which any
registration is being effected shall furnish the Company with such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing as shall be required by law or
by the Securities and Exchange Commission in connection therewith.

          8.4  REGISTRATION RIGHTS EQUAL OR SUPERIOR.  The Company shall not
grant any registration rights or register any securities for the account of any
person other than holders of Registration Stock unless permitted to do so by the
written consent of the holders of not less than 67% of the Registration Stock
(such securities being the "Subordinate Shares").

          8.5  EXPENSES, ETC.  All expenses in connection with the preparation
and filing of any registration statement under this Section 8, any registration
or qualification under the securities or "Blue Sky" laws of states in which the
offering will be made under such registration statement, and any filing fee of
the National Association of Securities Dealers, Inc. relating to such offering,
shall be borne in full by the Company, except for any (i) underwriters' or
brokers' commissions applicable to the shares to be sold by a holder of
Registration Stock, (ii) fees required to be paid by a selling shareholder
rather than the Company in order to comply with "Blue Sky" or state securities
laws, (iii) other fees or expenses expressly applicable to securities being sold
by the selling shareholder, and (iv) fees or expenses of any selling
shareholders' counsel.

          8.6  INDEMNIFICATION.  The Company shall indemnify the selling holders
of Registration Stock, and, to the extent required in any agreement with any
underwriter or broker-dealer through whom the Registration Stock may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities, expenses or actions in respect
thereof (under the Securities Act or common law or otherwise) caused by any
untrue 

                                       22
<PAGE>
 
statement or alleged untrue statement of a material fact contained in any
registration statement under which such Registration Stock was registered under
the Securities Act, any preliminary or final prospectus contained therein, or
any amendment or supplement thereto (unless cured by an amendment or supplement
to the prospectus delivered to the selling holders prior to the sales of the
Registration Stock that is subject to the claimed right of indemnification), or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registration Stock
that is subject to the claimed right of indemnification); and will reimburse the
selling holders of Registration Stock for any legal or other out-of-pocket
expenses reasonably incurred by such selling holders in connection with
investigating or defending against such loss, claim, damage, liability or
action; except insofar as such losses, claims, damages, liabilities or expenses
are caused by any untrue statement or omission contained in information
furnished in writing to the Company by such selling holders expressly for use
therein.  In connection with any such registration statement, the selling
holders of Registration Stock will furnish the company in writing such
information as may reasonably be requested by the Company for use in any such
registration statement or prospectus and will indemnify the Company, its
directors and officers, and, to the extent required in any agreement with any
underwriter or broker-dealer, each such underwriter or broker-dealer and each
person, if any, who controls the Company or any underwriter or broker-dealer
(within the meaning of the Securities Act) against any losses, claims, damages,
liabilities, expenses and actions in respect thereof (under the Securities Act
or common law or otherwise) caused by any untrue statement or alleged untrue
statement of a material fact required to be stated in such registration
statement or prospectus and necessary to make the statements therein not
misleading; and will reimburse the Company for any legal or other out-of-pocket
expenses reasonably incurred by it in connection with investigating or defending
against such loss, claim, damage, liability or action; but only to the extent
that such untrue statement or omission was contained in information so furnished
in writing by the selling holders of Registration Stock expressly for use
therein, and only to the extent of proceeds received by the selling holders of
Registration Stock in the offering.  The Company further agrees and the selling
shareholders shall agree that, in connection with any underwritten public
offering, the Company also will enter into customary contribution arrangements
with the selling holders of Registration Stock and the underwriters or broker-
dealers through whom the Registration Stock may be sold, with respect to
situations in which indemnification is potentially unavailable.

          8.7  WITHDRAWAL.  If a public offering is not completed within nine
months after the effective date of any registration statement filed by the
Company pursuant to Section 8.1(b), other than an offering under Rule 415 as
described in Section 8.2(a), the Company reserves the right, at its option, to
withdraw from registration any securities offered by the Company which have not
been sold during such period, provided that no securities offered by any holder
of Registration Stock shall be withdrawn without the consent of the holders of
50% of the Registration Stock.

          8.8  EXCHANGE ACT.  As promptly as possible following receipt of a
written request therefor from the holders of 50% of the outstanding Registration
Stock at any time while the Company either (a) is subject to periodic reporting
pursuant to Section 15(d) of the Exchange Act or (b) has 300 or more
shareholders of record, the Company shall register its Common Stock 

                                       23
<PAGE>
 
under Section 12 of the Exchange Act, arrange for its Common Stock to be listed
on a national stock exchange or included for quotation on the Nasdaq National
Market, as requested, and shall keep effective such registration and maintain
such listing or inclusion, and shall use its best efforts timely to file such
information, documents and reports as the Securities and Exchange Commission may
require or prescribe that the Company file in connection therewith. The Company
will, at the request of any holder of Registration Stock, advise such holder in
writing as to whether all reports required to be filed by the Company under
Section 13 of the Exchange Act during the 12 months preceding such request (or
for such shorter period as the Company was required to file such reports) have
been filed, and any other information which the holder may reasonably require in
order to comply with Rule 144, or any other comparable rule, as then in effect.

     9.   EVENTS OF DEFAULT.

     Each of the following shall constitute an Event of Default under this
Agreement:

          9.1  DEFAULT ON PAYMENTS TO THE INVESTOR.  The failure of the Company
to make (a) any principal or interest payment on the Debenture when due, or (b)
any other payment upon any other written obligation of the Company to the
Investor within 15 days after written notice from the Investor to the Company;
regardless of whether any such failure to make the payments described in (a) and
(b) above is due to a legal inability or the incapacity of the Company to make
any such payments.

          9.2  INFORMATION, REPRESENTATIONS AND WARRANTIES.  Any information
furnished or representation or warranty made or given by the Company herein
shall prove to have been untrue when made or given in any material respect or
shall have omitted to state a material fact respecting the matters set forth
therein necessary to make the matters set forth therein not misleading.

          9.3  COVENANTS AND AGREEMENTS.  The failure of the Company to observe,
perform or abide by any other covenant, warranty, agreement or provision in any
of the Transaction Documents, which failure is not cured to the Investor's
reasonable satisfaction within 30 days after written notice from the Investor to
the Company of its occurrence; provided, however, that no Event of Default shall
be considered to have occurred if the failure is not the failure to pay money
and is of such a nature that it reasonably cannot be cured within the Cure
Period, but if it is curable and the Company in good faith begins efforts to
cure it within the Cure Period and continues diligently to do so, the Company
shall have an additional 30 days from the date on which the Cure Period ends to
effect the cure.  If the failure continues after the expiration of such
additional 30 day period, regardless of whether such failure might be curable at
some time beyond such additional 30 day period, such failure shall nevertheless
be considered an Event of Default.

          9.4  DEFAULT ON OTHER OBLIGATIONS.  The occurrence of a material
default following the expiration of any applicable cure period, if any, in any
material obligation of the Company or any violation of law or refusal of
regulatory permission which has a material adverse effect on the Company's
operations.

                                       24
<PAGE>
 
          9.5  CERTAIN EVENTS AS TO THE COMPANY.  The Company shall (A) admit in
writing its inability to pay its debts generally as they become due; (B) file a
petition or answer or consent seeking relief under the Federal Bankruptcy Code,
as now constituted or hereafter amended, or any other applicable federal or
state bankruptcy or insolvency law or other similar law, not discharged or
vacated or set aside or stayed within 45 days; (C) consent to the institution of
proceedings under any law referenced in (B) above, not discharged or vacated or
set aside or stayed within 45 days, or to the filing of any such petition, not
discharged or vacated or set aside or stayed within 45 days or to the
appointment or taking possession of a receiver, liquidator, assignee, trustee,
custodian (or other similar official) of the Company or any subsidiary or of any
substantial part of their property; (D) fail generally to pay its debts as such
debts become due, or take corporate action in furtherance of any such action;
(E) make an assignment for the benefit of its creditors; or (F) fail to meet any
of its material monetary obligations; provided, however, that no Event of
Default shall be considered to have occurred under subsection 9.5(F) if the
failure to meet such material monetary obligations is due to a good faith
dispute between such parties, which dispute shall continue for no more than  30
days; provided; further, that upon the expiration of such 30 day period, the
Company shall have, upon notice to the Investor an additional 30 day period to
resolve the dispute.  If the dispute is not resolved after the expiration of
such additional 30 day period, regardless whether such dispute may be resolved
at some time beyond such additional 30 day period, such failure under subsection
9.5(F) shall nevertheless be considered an Event of Default.

     10.  RIGHTS OF INVESTOR UPON DEFAULT.

          10.1 RIGHTS ON DEFAULT.  If there shall occur and be continuing an
Event of Default as defined in the foregoing Section 9, as long as the Debenture
is outstanding, the Investor may, by written notice to the Company, declare the
Company to be in default hereunder, whereupon, if the Investor so specifies in
such notice, the Debenture and all other indebtedness of the Company to the
Investor now or hereafter incurred, shall become immediately due and payable
without further demand, presentation or notice of any kind.

          10.2 ADDITIONAL RIGHTS.  The Investor shall have such additional
rights and remedies as are contained herein, in the Debenture, the Warrant, the
Class B Preferred Stock, or in any other documents and agreements delivered or
given in connection herewith, and all rights which it might have at law or
equity, all of which rights and remedies shall be cumulative.

     11.  LOCK-UP AGREEMENT.  In the event that the Company determines to effect
an underwritten initial public offering, the Investor agrees that, for a period
of 180 days following the effective date of any registration filed in connection
therewith, the Investor will not directly or indirectly sell, transfer or
otherwise dispose of, any shares of Class B Preferred Stock, any shares of
Common Stock, or any right to acquire shares of Common Stock owned by the
Investor without the prior written consent of the underwriter(s) of such initial
public offering.

     12.  FURTHER ASSURANCE.  The Company and the Investor agree to execute and
deliver all such other instruments and take all such other actions as any party
may reasonably request from time to time after the date hereof and without
payment of further consideration, in order to effectuate the transactions
provided for herein.  The parties shall cooperate fully with each other 

                                       25

and with their respective counsel and accountants in connection with any steps

hereof may be changed, waived, discharged or terminated other than by an

              (a)  The Investor (i) is acquiring the Debenture and the Warrant
         and (ii) upon conversion of the Debenture or the Class B Preferred
         Stock, or upon exercise of the Warrant, will acquire the applicable
         Conversion Shares then issuable, for investment for its own accounts
         and not with a view to, or for resale in connection with, any
         distribution of the Securities. The Investor understands

                                       10
<PAGE>
 
         that the Securities have not been registered under the Securities Act,
         or under any state securities or "Blue Sky" laws, and, as a result, are
         subject to substantial restrictions on transfer. The Investor
         acknowledges that the Securities must be held indefinitely unless
         subsequently registered under the Securities Act and any applicable
         state securities or "Blue Sky" laws, or exemptions from registration
         under the Securities Act and such laws are available; provided,
         however, that by making the representations herein, the Investor does
         not agree to hold any of the Securities for any minimum or other
         specific term and reserves the right to dispose of the Securities at
         any time in accordance with or pursuant to a registration statement or
         an exemption from registration under the Securities Act and any
         applicable state securities or "Blue Sky" laws.

              (b)  This Agreement has been duly executed and delivered by the
         Investor and constitutes a valid and legally binding obligation of the
         Investor, enforceable in accordance with its terms, subject, as to
         enforcement, to bankruptcy, insolvency, reorganization and other laws
         of general applicability relating to or affecting creditors rights and
         to general equity principles.

              (c)  The Investor is an "accredited investor," as that term is
         defined in Rule 501(a) of Regulation D under the Securities Act.

              (d)  [STATE REPRESENTATION]

         4.2  LEGENDS.  The Investor understands that the certificates or other
instruments representing the Debenture and the Warrant and, until such time as
the sale of the Conversion Shares have been registered under the Securities Act,
the stock certificates representing the Conversion Shares, except as set forth
below, shall bear a restrictive legend in substantially the following form:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
         SECURITIES LAWS AND MAY NOT BE TRANSFERRED IN THE ABSENCE OF SUCH
         REGISTRATION OR AN EXEMPTION THEREFROM UNDER SUCH ACT AND SUCH LAWS.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Securities upon which it is
stamped if, unless otherwise required by state securities laws, (i) such
Securities are registered for sale under the Securities Act, (ii) in connection
with a sale transaction, such holder provides the Company with an opinion of
counsel, in a form reasonably acceptable to the Company's counsel, to the effect
that a public sale, assignment or transfer of such Securities may be made
without registration under the Securities Act, or (iii) such holder provides the
Company with an opinion of counsel, in a form reasonably acceptable to the
Company's counsel, that such Securities can be sold pursuant to Rule 144(k)
promulgated under the Securities Act (or a successor rule thereto) ("Rule 144").
The Investor acknowledges, covenants and agrees to sell the Securities
represented by a certificate(s) from which the legend has been removed, only
pursuant to (i) a registration statement effective 

                                       11
<PAGE>
 
under the Securities Act, or (ii) advice of counsel that such sale is exempt
from registration required by Section 5 of the Securities Act.

or impaired by any investigation made by any person or persons.

have also waived such covenant), until the earlier of (i) such time as the

         the Company for approval and acceptance or for required further
         revision until such approval and acceptance is obtained.

In the event that the Company at any time hereafter is required, by law or by
generally accepted accounting principles, to consolidate its financial
statements with those of a subsidiary corporation, the Company shall thereafter
furnish the financial statements required by this Section 6.1 on a consolidated
basis, and the monthly and annual financial statements specified above shall be
furnished with consolidating financial statements.

         6.10 COMPLIANCE WITH LAWS. The Company shall comply with all laws,
rules and regulations of all governmental authorities and agencies applicable to
the Company, its business or its properties, the failure to comply with which
might have a material adverse effect on the Company.

     7.  NEGATIVE COVENANTS.  The Company hereby covenants that as long as the

              (d)  except as contemplated by this Agreement, amend the Articles

purchase any of the securities of the Company, other than as required, permitted

         7.4  AGREEMENTS. The Company shall not enter into any contract,
agreement, lease or other instrument which, by its terms, restricts, in any

perform under the Transaction Documents.

         7.5  INSIDER TRANSACTIONS. Except as disclosed in Schedules 3.21 and
                                                           --------------

     8.  REGISTRATION AND RELATED RIGHTS.

         8.1  PIGGYBACK REGISTRATION.

              (a)  As used in this Section 8, "Registration Stock" shall mean
         any Securities or any other shares of Common Stock, Class B Preferred
         Stock or other securities received by holders of the Securities upon
         any stock split, stock dividend, recapitalization, merger,
         consolidation or similar event; provided, however, that Registration
         Stock shall not include any Securities or such other securities
         disposed of pursuant to one or more registration statements under the
         Securities Act, or which have been sold pursuant to Rule 144 (as
         previously defined) or which have otherwise been sold without
         registration under the Securities Act. For purposes of this Section 8,
         any record holder of securities convertible into Registration Stock (or
         exercisable for or payable in Registration Stock) shall be deemed to be
         the holder of the Registration Stock issuable upon such conversion
         and/or exercise and/or payment.

              (b)  If the Company should seek to register under the Securities
         Act or qualify any of the securities holdings of the Company or any of
         its shareholders (except in connection with any stock option plan,
         stock purchase plan, savings or similar plan or an acquisition, merger
         or exchange of stock, to be registered on Forms S-4, S-8 or any
         successor forms under the Securities Act) and if the form of
         registration statement proposed to be used otherwise may be used for
         the registration of the Registration Stock, then, on each such
         occasion, the Company shall furnish the Investor with at least 30 days
         prior written notice thereof. At the written request of the Investor,
         given within 20 days after the receipt of such

                                       17
<PAGE>
 
         notice, the Company will use its best efforts to cause all of the
         Registration Stock for which registration shall have been requested by
         the Investor to be included in such registration statement. In the
         event that the proposed registration by the Company is, in whole or in
         part, an underwritten public offering of securities of the Company, and
         the managing underwriter determines and advises in writing that the
         inclusion of all Registration Stock proposed to be included in the
         underwritten public offering and other issued and outstanding shares of
         Common Stock proposed to be included therein by persons other than (i)
         holders of Registration Stock or (ii) holders of Subordinate Shares (as
         defined in Section 8.4) with rights equal to those of the holders of
         Registration Stock ("Other Registration Stock") (such other shares
         which are not Registration Stock or Other Registration Stock being the
         "Other Shares") would interfere with the successful marketing
         (including pricing) of the securities, then the number of shares of
         Registration Stock, Other Registration Stock and Other Shares to be
         included in such underwritten public offering shall be reduced first,
         pro rata among the holders of Other Shares; second, if necessary, pro
         rata among the holders of Registration Stock and Other Registration
         Stock combined, based on the number of shares requested by holders
         thereof to be registered in such underwritten public offering; and
         lastly, if necessary, among the Company's shares requested by the
         Company to be registered; provided, however, that the holders of
         Registration Stock do not then elect to exercise their rights under
         Section 8.2; and, further provided, that in no event, without the
         consent of the holders of at least 67% of the Registration Stock, shall
         the percentage of the Registration Stock that is included in such
         registration statement be less than the percentage of the securities of
         any other shareholder included therein. In the event that the Company
         offers any of its securities in an offering exempt from registration
         under the Securities Act pursuant to Regulation A, the Company will
         provide to the holders of Registration Stock rights comparable to those
         provided herein.

         8.2  DEMAND REGISTRATION.

              (a)  After the closing of an underwritten offering of the Common
         Stock, if at any time the Company is requested in writing by the
         holders of not less than 67% of the Registration Stock to effect the
         registration under the Securities Act of at least 33 1/3% of the
         Registration Stock, the Company shall promptly give written notice of
         such proposed registration to all record holders of Registration Stock.
         Such holders shall have the right, by giving written notice to the
         Company within 30 days from receipt of the Company's notice, to elect
         to have included in such registration such of their Registration Stock
         as such holders may request in such notice of election. Thereupon, the
         Company shall, as expeditiously as possible, use its best efforts to
         effect the registration, on a form of general use under the Securities
         Act, of all shares of Registration Stock which the Company has been
         requested to register; provided, however, that if the holders of not
         less than 67% of the Registration Stock shall so request (and at least
         50% of the Registration Stock is being registered), the Company shall
         file such registration statement pursuant to Rule 415 or any successor
         rule or regulation under the Securities Act, so as to permit the
         continuous or delayed offering of the

                                       18
<PAGE>
 
         Registration Stock in accordance with the intended method of
         disposition specified in the notice of the exercise of rights under
         this Section 8.2(a), to the extent such offering qualifies under such
         rule or regulation, but in no event shall the Company be required to
         maintain the effectiveness of such registration statement beyond a two
         year period. The Company shall be obligated to cause to become
         effective one registration statement pursuant to which Registration
         Stock is sold under this Section 8.2(a).

              (b)  In addition and not in limitation of the rights set forth in
         Sections 8.1(b) and 8.2(a), at such time as the Company shall have
         qualified for the use of a short form Form S-3 in an offering solely
         for the accounts of persons other than the Company (or any similar form
         or forms promulgated by the Securities and Exchange Commission), the
         holders of not less than 67% of the Registration Stock shall have the
         right to request an unlimited number of registrations on Form S-3 or
         other similar forms. Holders shall have the right, by giving written
         notice to the Company within 20 days from receipt of notice from the
         Company of such request, to elect to have included in such registration
         such of their Registration Stock as such holders may request in such
         notice of election. Thereupon, the Company shall, as expeditiously as
         possible, use its best efforts to effect the registration, on Form S-3
         of all shares of Registration Stock which the Company has been
         requested to register. The Company shall not be required to effect any
         such registration more than once every twelve months. Registrations
         effected on Form S-3 shall not be considered to be demand registrations
         pursuant to Section 8.2(a) hereof.

              (c)  The Company may include in a registration requested under
         this Section 8.2 any additional authorized shares of the Common Stock
         of the Company, whether or not issued, for sale by the Company or for
         sale by others; provided, however, that such shares shall not be
         included to the extent that the holders of a majority of the shares of
         Registration Stock included therein determine in good faith that the
         inclusion of such shares will interfere with the successful marketing
         of the shares of Registration Stock to be included therein; and,
         provided, further, that, upon the election of the holders of a majority
         of the shares of Registration Stock included therein, or if the number
         of shares to be so included equals or exceeds the number of shares of
         Registration Stock included therein by the holders of Registration
         Stock, such registration shall be deemed to be a registration pursuant
         to Section 8.1(b) hereof.

              (d)  The underwriter and the terms of the underwriting for any
         registration pursuant to this Section 8.2 shall be mutually acceptable
         to the Company and the Investor.

              (e)  Notwithstanding anything contained in this Agreement to the
         contrary:

                   (i) The Company reserves the right to delay any such
              registration pursuant to Section 8 for a period of not more than
              sixty days, 

                                       19
<PAGE>
 
              or to withhold efforts to cause such registration statement to
              become effective for a period of not more than sixty days, if the
              Board of Directors of the Company determines in good faith that
              such registration might (A) interfere with or affect the
              negotiation or completion of any material transaction that is
              being contemplated by the Company, or (B) involve initial or
              continuing disclosure obligations materially adverse to the best
              interests of the Company's shareholders. If, after a registration
              statement becomes effective, the Company advises the holders of
              the Registration Stock covered by such registration statement that
              the Company considers it appropriate for the registration
              statement to be amended, the holders of such shares shall suspend
              any further sales of their registered shares until the Company
              advises them that the registration statement has been amended. The
              time periods referred to in this Section 8 shall be extended for
              an additional number of business days during which the rights to
              sell shares was suspended.

                   (ii) The Company shall not be obligated to file a
              registration statement pursuant to Section 8.2 within three months
              after the effective date of any registration under which piggyback
              rights were granted pursuant to Section 8.1.

         8.3  FURTHER OBLIGATIONS OF THE COMPANY. Whenever the Company is
required to register any of the Registration Stock pursuant to any of the
provisions of this Section 8, the Company shall also be obligated to:

              (a)  prepare for filing and file with the Securities and Exchange
         Commission promptly thereafter a registration statement and such
         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 (but, other than
         as otherwise provided in Section 8.2(a), in no event more than nine
         months) to complete the proposed public offering;

              (b)  furnish to each selling holder so requesting such copies of
         preliminary and final prospectus and such other documents as said
         holder may reasonably request to facilitate the public offering of such
         holder's Registration Stock;

              (c)  use its best efforts to register or qualify the Registration
         Stock covered by said registration statement under the securities or
         "Blue Sky" laws of such jurisdictions as the holders of Registration
         Stock may reasonably request, to keep such registration or
         qualification in effect for so long as such registration statement
         remains in effect, and do any and all other acts and things that may be
         reasonably necessary or advisable to enable such seller to consummate
         the disposition in such jurisdictions of its Registration Stock covered
         by such registration statement, except that the Company shall not for
         any such purpose be

         thereto is required to be delivered under the Securities Act, upon
         discovery that, or upon the happening of any event as a result of
         which, the prospectus included in such registration statement, as then
         in effect, includes an untrue statement of a material fact or omits to
         state any material fact required to be stated therein or necessary to
         make the statements therein not misleading in the light of the

         holder, prepare and furnish to such seller and holder a reasonable
         number of copies of a supplement to or an amendment of such prospectus

         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading in the light of the circumstances then existing;

         months, but not more than eighteen months, beginning with the first
         month of the first fiscal quarter after the effective date of such
         registration statement, which earnings statement shall satisfy the
         provisions of Section 13(a) of the Securities Exchange Act of 1934, as
         amended (the "Exchange Act"); and

              (i)  provide and cause to be maintained a transfer agent and
         registrar for all registrable securities covered by such registration
         statement from and after a date not later than the effective date of

                                       21
<PAGE>
 
If requested by the Company, each seller of Registration Stock as to which any
registration is being effected shall furnish the Company with such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing as shall be required by law or
by the Securities and Exchange Commission in connection therewith.

         8.4  REGISTRATION RIGHTS EQUAL OR SUPERIOR. The Company shall not grant
any registration rights or register any securities for the account of any person
other than holders of Registration Stock unless permitted to do so by the
written consent of the holders of not less than 67% of the Registration Stock
(such securities being the "Subordinate Shares").

         8.5  EXPENSES, ETC. All expenses in connection with the preparation and
filing of any registration statement under this Section 8, any registration or
qualification under the securities or "Blue Sky" laws of states in which the
offering will be made under such registration statement, and any filing fee of
the National Association of Securities Dealers, Inc. relating to such offering,
shall be borne in full by the Company, except for any (i) underwriters' or
brokers' commissions applicable to the shares to be sold by a holder of
Registration Stock, (ii) fees required to be paid by a selling shareholder
rather than the Company in order to comply with "Blue Sky" or state securities
laws, (iii) other fees or expenses expressly applicable to securities being sold
by the selling shareholder, and (iv) fees or expenses of any selling
shareholders' counsel.

         8.6  INDEMNIFICATION. The Company shall indemnify the selling holders
of Registration Stock, and, to the extent required in any agreement with any
underwriter or broker-dealer through whom the Registration Stock may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities, expenses or actions in respect
thereof (under the Securities Act or common law or otherwise) caused by any
untrue statement or alleged untrue statement of a material fact contained in any
registration statement under which such Registration Stock was registered under
the Securities Act, any preliminary or final prospectus contained therein, or
any amendment or supplement thereto (unless cured by an amendment or supplement
to the prospectus delivered to the selling holders prior to the sales of the
Registration Stock that is subject to the claimed right of indemnification), or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading (unless cured by an amendment or supplement to the prospectus
delivered to the selling holders prior to the sales of the Registration Stock
that is subject to the claimed right of indemnification); and will reimburse the
selling holders of Registration Stock for any legal or other out-of-pocket
expenses reasonably incurred by such selling holders in connection with
investigating or defending against such loss, claim, damage, liability or
action; except insofar as such losses, claims, damages, liabilities or expenses
are caused by any untrue statement or omission contained in information
furnished in writing to the Company by such selling holders expressly for use
therein. In connection with any such registration statement, the selling holders
of Registration Stock will furnish the company in writing such information as
may reasonably be requested by the Company for use in any such registration
statement or prospectus and will indemnify the Company, its directors and
officers, and, to the extent required in any agreement with any underwriter or
broker-dealer, each such underwriter or broker-dealer and each person, if any,
who controls the Company or any 

                                       22
<PAGE>
 
underwriter or broker-dealer (within the meaning of the Securities Act) against
any losses, claims, damages, liabilities, expenses and actions in respect
thereof (under the Securities Act or common law or otherwise) caused by any
untrue statement or alleged untrue statement of a material fact required to be
stated in such registration statement or prospectus and necessary to make the
statements therein not misleading; and will reimburse the Company for any legal
or other out-of-pocket expenses reasonably incurred by it in connection with
investigating or defending against such loss, claim, damage, liability or
action; but only to the extent that such untrue statement or omission was
contained in information so furnished in writing by the selling holders of
Registration Stock expressly for use therein, and only to the extent of proceeds
received by the selling holders of Registration Stock in the offering. The
Company further agrees and the selling shareholders shall agree that, in
connection with any underwritten public offering, the Company also will enter
into customary contribution arrangements with the selling holders of
Registration Stock and the underwriters or broker-dealers through whom the
Registration Stock may be sold, with respect to situations in which
indemnification is potentially unavailable.

         8.7  WITHDRAWAL. If a public offering is not completed within nine
months after the effective date of any registration statement filed by the
Company pursuant to Section 8.1(b), other than an offering under Rule 415 as
described in Section 8.2(a), the Company reserves the right, at its option, to
withdraw from registration any securities offered by the Company which have not
been sold during such period, provided that no securities offered by any holder
of Registration Stock shall be withdrawn without the consent of the holders of
50% of the Registration Stock.

         8.8  EXCHANGE ACT. As promptly as possible following receipt of a
written request therefor from the holders of 50% of the outstanding Registration
Stock at any time while the Company either (a) is subject to periodic reporting
pursuant to Section 15(d) of the Exchange Act or (b) has 300 or more
shareholders of record, the Company shall register its Common Stock under
Section 12 of the Exchange Act, arrange for its Common Stock to be listed on a
national stock exchange or included for quotation on the Nasdaq National Market,
as requested, and shall keep effective such registration and maintain such
listing or inclusion, and shall use its best efforts timely to file such
information, documents and reports as the Securities and Exchange Commission may
require or prescribe that the Company file in connection therewith. The Company
will, at the request of any holder of Registration Stock, advise such holder in
writing as to whether all reports required to be filed by the Company under
Section 13 of the Exchange Act during the 12 months preceding such request (or
for such shorter period as the Company was required to file such reports) have
been filed, and any other information which the holder may reasonably require in
order to comply with Rule 144, or any other comparable rule, as then in effect.

     9.  EVENTS OF DEFAULT.

     Each of the following shall constitute an Event of Default under this
Agreement:

         9.1  DEFAULT ON PAYMENTS TO THE INVESTOR. The failure of the Company to
make (a) any principal or interest payment on the Debenture when due, or (b) any
other payment upon any other written obligation of the Company to the Investor
within 15 days after written

                                       23
<PAGE>
 
notice from the Investor to the Company; regardless of whether any such failure
to make the payments described in (a) and (b) above is due to a legal inability
or the incapacity of the Company to make any such payments.

         9.2  INFORMATION, REPRESENTATIONS AND WARRANTIES.  Any information
furnished or representation or warranty made or given by the Company herein
shall prove to have been untrue when made or given in any material respect or
shall have omitted to state a material fact respecting the matters set forth
therein necessary to make the matters set forth therein not misleading.

         9.3  COVENANTS AND AGREEMENTS.  The failure of the Company to observe,
perform or abide by any other covenant, warranty, agreement or provision in any
of the Transaction Documents, which failure is not cured to the Investor's
reasonable satisfaction within 30 days after written notice from the Investor to
the Company of its occurrence; provided, however, that no Event of Default shall
be considered to have occurred if the failure is not the failure to pay money
and is of such a nature that it reasonably cannot be cured within the Cure
Period, but if it is curable and the Company in good faith begins efforts to
cure it within the Cure Period and continues diligently to do so, the Company
shall have an additional 30 days from the date on which the Cure Period ends to
effect the cure.  If the failure continues after the expiration of such
additional 30 day period, regardless of whether such failure might be curable at
some time beyond such additional 30 day period, such failure shall nevertheless
be considered an Event of Default.

         9.4  DEFAULT ON OTHER OBLIGATIONS. The occurrence of a material default
following the expiration of any applicable cure period, if any, in any material
obligation of the Company or any violation of law or refusal of regulatory
permission which has a material adverse effect on the Company's operations.

         9.5  CERTAIN EVENTS AS TO THE COMPANY.  The Company shall (A) admit in
writing its inability to pay its debts generally as they become due; (B) file a
petition or answer or consent seeking relief under the Federal Bankruptcy Code,
as now constituted or hereafter amended, or any other applicable federal or
state bankruptcy or insolvency law or other similar law, not discharged or
vacated or set aside or stayed within 45 days; (C) consent to the institution of
proceedings under any law referenced in (B) above, not discharged or vacated or
set aside or stayed within 45 days, or to the filing of any such petition, not
discharged or vacated or set aside or stayed within 45 days or to the
appointment or taking possession of a receiver, liquidator, assignee, trustee,
custodian (or other similar official) of the Company or any subsidiary or of any
substantial part of their property; (D) fail generally to pay its debts as such
debts become due, or take corporate action in furtherance of any such action;
(E) make an assignment for the benefit of its creditors; or (F) fail to meet any
of its material monetary obligations; provided, however, that no Event of
Default shall be considered to have occurred under subsection 9.5(F) if the
failure to meet such material monetary obligations is due to a good faith
dispute between such parties, which dispute shall continue for no more than 30
days; provided, however, that upon the expiration of such 30 day period, the
Company shall have, upon notice to the Investor an additional 30 day period to
resolve the dispute.  If the dispute is not resolved after the expiration of
such additional 30 day period, regardless whether such dispute may be resolved
at some time 

                                       24
<PAGE>
 
beyond such additional 30 day period, such failure under subsection 9.5(F) shall
nevertheless be considered an Event of Default.

     10.  RIGHTS OF INVESTOR UPON DEFAULT.

          10.1  RIGHTS ON DEFAULT. If there shall occur and be continuing an
Event of Default as defined in the foregoing Section 9, as long as the Debenture
is outstanding, the Investor may, by written notice to the Company, declare the
Company to be in default hereunder, whereupon, if the Investor so specifies in
such notice, the Debenture and all other indebtedness of the Company to the
Investor now or hereafter incurred, shall become immediately due and payable
without further demand, presentation or notice of any kind.

          10.2  ADDITIONAL RIGHTS. The Investor shall have such additional
rights and remedies as are contained herein, in the Debenture, the Warrant, the
Class B Preferred Stock, or in any other documents and agreements delivered or
given in connection herewith, and all rights which it might have at law or
equity, all of which rights and remedies shall be cumulative.

     11.  LOCK-UP AGREEMENT.  In the event that the Company determines to effect
an underwritten initial public offering, the Investor agrees that, for a period
of 180 days following the effective date of any registration filed in connection
therewith, the Investor will not directly or indirectly sell, transfer or
otherwise dispose of, any shares of Class B Preferred Stock, any shares of
Common Stock, or any right to acquire shares of Common Stock owned by the
Investor without the prior written consent of the underwriter(s) of such initial
public offering.

     12.  FURTHER ASSURANCE.  The Company and the Investor agree to execute and
deliver all such other instruments and take all such other actions as any party
may reasonably request from time to time after the date hereof and without
payment of further consideration, in order to effectuate the transactions
provided for herein.  The parties shall cooperate fully with each other and with
their respective counsel and accountants in connection with any steps required
to be taken as part of their respective obligations under this Agreement.

hereof may be changed, waived, discharged or terminated other than by an
agreement in writing signed by all of the parties hereto.

          13.2  GOVERNING LAW.  This Agreement and all questions relating to its
validity, interpretation, performance and enforcement shall be governed by and

parties hereto, and their respective representatives, successors and assigns.

     VIII. Registration and Related Rights.
           ------------------------------- 

           8.1 Piggyback Registration.
               ---------------------- 

               (a)  As used in this Section 8, "Registration Stock" shall mean
the Conversion Shares (as defined in Section 1.4), and any shares of Common
Stock issued in respect of the Preferred Stock or the Conversion Shares upon any
stock split, stock dividend, recapitalization, merger, consolidation or similar
event; provided, however, that Registration Stock shall not include any such 
       --------  ------- 
shares disposed of pursuant to one or more registration statements under the
Securities Act, or which have been sold pursuant to Rule 144 under the
Securities Act or which have otherwise been sold without registration under the
Securities Act. For purposes of this Section 8, any record holder of securities
convertible into Registration Stock 

                                       19
<PAGE>
 
(or exercisable for securities which are convertible into Registration Stock)
shall be deemed to be the holder of the Registration Stock issuable upon such
exercise and/or conversion.

               (b)  If the Company shall seek to register under the Securities
Act or qualify any of the securities holdings of the Company or any of its
shareholders (except in connection with any stock option plan, stock purchase
plan, savings or similar plan or an acquisition, merger or exchange of stock, to
be registered on Forms S-4, S-8 or any successor forms under the Securities Act)
and if the form of registration statement proposed to be used otherwise may be
used for the registration of the Registration Stock (as herein defined), then,
on each such occasion, the Company shall furnish the Investor with at least 30
days prior written notice thereof. At the written request of the Investor, given
within 20 days after the receipt of such notice, the Company will use its best
efforts to cause all of the Registration Stock for which registration shall have
been requested by the Investor to be included in such registration statement. In
the event that the proposed registration by the Company is, in whole or in part,
an underwritten public offering of securities of the Company, and the managing
underwriter determines and advises in writing that the inclusion of all
Registration Stock proposed to be included in the underwritten public offering
and other issued and outstanding shares of Common Stock proposed to be included
therein by persons other than (i) holders of Registration Stock or (ii) holders
of Subordinate Stock (as defined in Section 8.4) with rights equal to those of
the holders of Registration Stock ("Other Registration Stock) (such other shares
which are not Registration Stock or Other Registration Stock being the "Other
Shares") would interfere with the successful marketing (including pricing) of
the securities, then the number of shares of Registration Stock, Other
Registration Stock and Other Shares to be included in such underwritten public
offering shall be reduced first, pro rata among the holders of Other Shares;
second, if necessary, pro rata among the holders of Registration Stock and Other
Registration Stock combined, based upon the number of shares requested by
holders thereof to be registered in such underwritten public offering; and
lastly, if necessary, among the Company's shares requested by the Company to be
registered; provided, however, that the holders of Registration Stock do not
            --------  -------                                               
then elect to exercise their rights under Section 8.2; and, further provided,
                                                            ------- -------- 
that in no event, without the consent of the holders of at least 67% of the
Registration Stock, the percentage of the Registration Stock that is included in
such registration statement shall not be less than the percentage of the
securities of any other shareholder included therein.  In the event that the
Company offers any of its securities in an offering exempt from registration
under the Securities Act pursuant to Regulation A, the Company will provide to
the holders of Registration Stock rights comparable to those provided herein.

          8.2  Demand Registration.
               ------------------- 

               (a)  If at any time, the Company shall be requested in writing by
the holders of not less than 67% of the Registration Stock to effect the
registration under the Securities Act of at least 33 1/3% of the Registration
Stock, the Company shall promptly give written notice of such proposed
registration to all record holders of Registration Stock. Such holders shall
have the right, by giving written notice to the Company within 30 days from
receipt of the Company's notice, to elect to have included in such registration
such of their Registration Stock as such holders may request in such notice of
election. Thereupon, the Company shall, as expeditiously as possible, use its
best efforts to effect the registration, on a form of general use under the
Securities Act, of all shares of Registration Stock which the Company has been

                                       20
<PAGE>
 
requested to register; provided, however, that if the holders of not less than
                       --------  -------                                      
67% of the Registration Stock shall so request (and at least 50% of the
Registration Stock is being registered), the Company shall file such
registration statement pursuant to Rule 415 or any successor rule or regulation
under the Securities Act, so as to permit the continuous or delayed offering of
the Registration Stock in accordance with the intended method of disposition
specified in the notice of the exercise of rights under this Section 8.2(a), to
the extent such offering qualifies under such rule or regulation, but in no
event shall the Company be required to maintain the effectiveness of such
registration statement beyond a two year period.  The Company shall be obligated
to cause to become effective one registration statement pursuant to which
Registration Stock is sold under this Section 8.2(a).

          (b)  In addition and not in limitation of the rights set forth in
Sections 8.1(b) and 8.2(a), at such time as the Company shall have qualified for
the use of Form S-2 or Form S-3 in an offering solely for the accounts of
persons other than the Company (or any similar form or forms promulgated by the
Securities and Exchange Commission), the holders of not less than 67% of the
Registration Stock shall have the right to request an unlimited number of
registrations on Form S-2 or Form S-3 or other similar forms.  Such holders
shall have the right, by giving written notice to the Company within 20 days
from receipt of the Company's notice, to elect to have included in such
registration such of their Registration Stock as such holders may request in
such notice of election.  Thereupon, the Company shall, as expeditiously as
possible, use its best efforts to effect the registration, on Form S-2 or Form
S-3 of all shares of Registration Stock which the Company has been requested to
register.  The Company shall not be required to effect any such registration
more than once every twelve months.  Registrations effected on Form S-2 or Form
S-3 shall not be considered to be demand registrations pursuant to Section
8.2(a) hereof.

          (c)  The Company may include in a registration requested under this
Section 8.2 any additional authorized shares of the Common Stock of the Company,
whether or not issued, for sale by the Company or for sale by others; provided,
                                                                      -------- 
however, that such shares shall not be included to the extent that the holders
- -------                                                                       
of a majority of the shares of Registration Stock included therein determine in
good faith that the inclusion of such shares will interfere with the successful
marketing of the shares of Registration Stock to be included therein; and,
provided, further, that, upon the election of the holders of a majority of the
- --------  -------                                                             
shares of Registration Stock included therein, or if the number of shares to be
so included equals or exceeds the number of shares of Registration Stock
included therein by the holders of Registration Stock, such registration shall
be deemed to be a registration pursuant to Section 8.1(b) hereof.

          (d)  The underwriter and the terms of the underwriting for any
registration pursuant to this Section 8.2 shall be mutually acceptable to the
Company and the Investor.

          (e)  Notwithstanding anything contained in this Agreement to the
contrary:

               (i)  The Company reserves the right to delay any such
registration pursuant to Section 8 for a period of not more than sixty days, or
to withhold efforts to cause such registration statement to become effective for
a period of not more than sixty days,

                                       21
<PAGE>
 
if the Board of Directors of the Company determines in good faith that such
registration might (A) interfere with or affect the negotiation or completion of
any material transaction that is being contemplated by the Company, or (B)
involve initial or continuing disclosure obligations materially adverse to the
best interest of the Company's shareholders. If, after a registration statement
becomes effective, the Company advises the holders of the Registration Stock
covered by such registration statement that the Company considers it appropriate
for the registration statement to be amended, the holders of such shares shall
suspend any further sales of their registered shares until the Company advises
them that the registration statement has been amended. The time periods referred
to in this Article 8 shall be extended for an additional number of business days
during which the rights to sell shares was suspended.

                    (ii)  The Company shall not be obligated to file a
registration statement pursuant to Section 8.2 within three months after the
effective date of any registration under which piggyback rights were granted
pursuant to Section 8.1.

          8.3  Further Obligations of the Company.  Whenever the Company is
               ----------------------------------                          
required to register any of the Registration Stock pursuant to any of the
provisions of this Section 8, the Company shall also be obligated to do the
following:

               (a)  Prepare for filing and file with the Securities and Exchange
Commission promptly thereafter a registration statement and such 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 (but,
other than as otherwise provided in Section 8.2(a), in no event more than nine
months) to complete the proposed public offering;

               (b)  Furnish to each selling holder so requesting such copies of
preliminary and final prospectus and such other documents as said holder may
reasonably request to facilitate the public offering of such holder's
Registration Stock;

               (c)  Use its best efforts to register or qualify the Registration
Stock covered by said registration statement under the securities or Blue Sky
laws of such jurisdictions as not less than 60% of the holders of Registration
Stock may reasonably request, to keep such registration or qualification in
effect for so long as such registration statement remains in effect, and do any
and all other acts and things that may be reasonably necessary or advisable to
enable such seller to consummate the disposition in such jurisdictions of its
Registration Stock covered by such registration statement, except that the
Company shall not for any such purpose be required to qualify generally to do
business as a foreign corporation in any jurisdiction wherein it would not, but
for the requirements of this subdivision (c), be obligated to be so qualified,
or to subject itself to taxation in any such jurisdiction, or to consent to
general service of process in any such jurisdiction;

               (d)  Furnish to the selling holders, and any underwriters or
broker-dealers through whom the Registration Stock may be sold, an opinion or
opinions of counsel for the Company and a "cold comfort" letter or letters of
the independent auditors for the Company, in form and substance customary for
similar offerings;

                                       22
<PAGE>
 
               (e)  Permit each selling holder or the selling holder's counsel
or other representatives, at the selling holder's expense, to inspect and copy
such corporate documents and records as may reasonably be requested by them;

               (f)  If so requested, furnish to each selling holder a copy of
all documents filed and all correspondence to or from the Securities and
Exchange Commission in connection with any such offering.

               (g)  Immediately notify each seller of Registration Stock covered
by such registration statement, at any time when a prospectus relating thereto
is required to be delivered under the Securities Act, upon discovery that, or
upon the happening of any event as a result of which, the prospectus included in
such registration statement, as then in effect, includes an untrue statement of
a material fact or omits to state any material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing, and at the request of any such seller or
holder, prepare and furnish to such seller and holder a reasonable number of
copies of a supplement to or an amendment of such prospectus as may be necessary
so that, as thereafter delivered to the purchasers of such Registration Stock,
such prospectus shall not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing;

               (h)  Otherwise use its best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and make
available to its security holders, as soon as reasonably practicable, an
earnings statement covering a period of at least twelve months, but not more
than eighteen months, beginning with the first month of the first fiscal quarter
after the effective date of such registration statement, which earnings
statement shall satisfy the provisions of subsection 11(a) of the Securities
Act;

               (i)  Provide and cause to be maintained a transfer agent and
registrar for all Registrable Securities covered by such registration statement
from and after a date not later than the effective date of such registration
statement; and

If requested by the Company, each seller of Registration Stock as to which any
registration is being effected shall furnish the Company with such information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing as shall be required by law or
by the Commission in connection therewith.

          8.4  Registration Rights Equal or Superior.  The Company shall not
               -------------------------------------                        
grant any registration rights or register any securities for the account of any
person other than holders of Registration Stock unless permitted to do so by the
written consent of the Required Holders; provided, however, that the Company
                                         --------  -------                  
shall be entitled to grant registration rights or register any securities for
the account of any person other than holders of Registration Stock without the
consent of the Designated Director as long as such rights applicable to such
securities are made subject and subordinate to, or no more than equal to the
rights of the holders of Registration Stock under Sections 8.1 and 8.2 (such
securities being the "Subordinate Shares").

          8.5  Expenses, Etc. All expenses in connection with the preparation
               -------------                                                  
and filing of any registration statement under this Section 8, any registration
or qualification under the securities or Blue Sky laws of states in which the
offering will be made under such registration statement, and any filing fee of
the National Association of Securities Dealers, Inc. relating to such offering,
shall be borne in full by the Company, except for any (i) underwriters' or
brokers' commissions applicable to the shares to be sold by a holder of
Registration Stock, (ii) fees required to be paid by a selling shareholder
rather than the Company in order to comply with Blue Sky or state securities
laws, (iii) other fees or expenses expressly applicable to securities being sold
by the selling shareholder and (iv) fees or expenses of any selling
shareholders' counsel.

          8.6  Indemnification. The Company shall indemnify the selling holders
               ---------------                                                  
of Registration Stock, and, to the extent required in any agreement with any
underwriter or broker-dealer through whom the Registration Stock may be sold,
any such underwriter or broker-dealer and each person, if any, who controls any
such underwriter or broker-dealer (within the meaning of the Securities Act)
against all losses, claims, damages, liabilities, expenses or actions in respect
thereof (under the Securities Act or common law or otherwise) caused by any
untrue statement or alleged untrue statement of a material fact contained in any
registration statement under which such Registration Stock were registered under
the Securities Act, any preliminary or final prospectus contained therein, or
any amendment or supplement thereto, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; and will reimburse the
selling holders of Registration Stock for any legal or other out-of-pocket
expenses reasonably incurred by such selling holders in connection with
investigating or defending against such loss, claim, damage, liability or
action; except insofar as such losses, claims, damages, liabilities or expenses
are caused by any untrue statement or omission contained in information
furnished in writing to the Company by such selling holders expressly for use
therein. In connection with any such registration statement, the selling holders
of Registration Stock will furnish the Company in writing such information as
may reasonably be requested by the Company for use in any such registration
statement or prospectus and will indemnify the Company, its directors and
officers, and, to the extent required in any agreement with any underwriter or
broker-dealer, each such underwriter or broker-dealer and each person, if any,
who controls the Company or any underwriter or broker-dealer (within the meaning
of the Securities Act) against any losses, claims, damages, liabilities,
expenses and actions in respect thereof (under the Securities Act or common law
or otherwise) resulting from any untrue statement or alleged untrue statement of
a material fact required to be stated in such registration statement or
prospectus and necessary to make the statements therein not misleading; and will
reimburse the Company for any legal or other out-of-pocket expenses reasonably
incurred by it in connection with investigating or defending against such loss,
claim, damage, liability or action; but only to the extent that such untrue
statement or omission was contained in information so furnished in writing by
the selling holders of Registration Stock expressly for use therein, and only to
the extent of proceeds received by the selling holders of Registration Stock in
the offering. The Company further agrees and the selling shareholder shall agree
that, in connection with any underwritten public offering, the Company also will
enter into customary contribution arrangements with the selling holders of
Registration Stock and the underwriters or broker-dealers through whom the
Registration Stock may be sold, with respect to situations in which
indemnification is potentially unavailable.

          8.7  Withdrawal. If a public offering is not completed within nine
               ----------                                                    
months after the effective date of any registration statement filed by the
Company pursuant to Section 8.1(b), other than an offering under Rule 415 as
described in Section 8.2(a), the Company reserves the right, at its option, to
withdraw from registration any securities offered by the Company which have not
been sold during such period, provided that no securities offered by any holder
of Registration Stock shall be withdrawn without the consent of the holders of
50% of the Registration Stock.

          8.8  Exchange Act. As promptly as possible following receipt of a
               ------------                                                 
written request therefor from the holders of 50% of the outstanding Registration
Stock at any time while the Company either (a) is subject to periodic reporting
pursuant to Section 15(d) of the Exchange Act or (b) has 300 or more
shareholders of record, the Company shall register its Common Stock under
Section 12 of the Exchange Act, arrange for its Common Stock to be listed on a
national stock exchange or included for quotation on Nasdaq or the Nasdaq
National Market, as requested, and shall keep effective such registration and
maintain such listing or inclusion, and shall use its best efforts timely to
file such information, documents and reports as the Securities and Exchange
Commission may require or prescribe that the Company file in connection
therewith. The Company will, at the request of any holder of Registration Stock,
advise such holder in writing as to whether all reports required to be filed by
the Company under Section 13 of the Exchange Act during the 12 months preceding
such request (or for such shorter period as the Company was required to file
such reports) have been filed, and any other information which the holder may
reasonably require in order to comply with Rule 144 under the Act, or any other
comparable rule, as then in effect.

     IX.  Preemptive Rights.
          ----------------- 

          9.1  Until the first to occur of (a) the Investor no longer owning the
Minimum Stock Amount or (b) the consummation of a Qualifying Public offering, if
at any time after the date of this Agreement, the Company issues or proposes to
issue any equity securities, other than (a) the Securities whose issuance is
contemplated by this Agreement; (b) up to an aggregate of 37,024 shares of
Common Stock issuable upon exercise of options granted under the ESOP if the
Original ESOP Amount is in effect, or down to an aggregate of 30,839 shares of
Common Stock issuable upon exercise of options granted under the ESOP if the
Decreased ESOP Amount is in effect; (c) up to an aggregate of 6,185 shares of
Common Stock issuable upon exercise of the Harris options; and shares of Common
Stock issued upon the exercise, exchange or conversion of any security as to
which the Investor had an opportunity to exercise its rights under this Section
9 (an "Issuance"), the Investor shall have the right to purchase up to its
Proportionate Percentage (as defined below) of the type of securities issued or
proposed to be issued in such Issuance on the same price and terms as the
Issuance (to the extent such price and terms are cash prices and terms). The
Investor's "Proportionate Percentage" shall be that percentage equal to the
ratio which (x) the number of shares of outstanding Common Stock then owned by
the Investor bears to (y) the aggregate number of shares of outstanding Common
Stock then owned by all shareholders of the Company. For purposes solely of the
computation required under clauses (x) and (y) above, the Investor holding
Preferred Stock shall be treated as having converted all of its Preferred Stock
into shares of Common Stock at the rate at which such Preferred Stock is
convertible at the time of delivery by the Company of the Option Notice (as
defined below), assuming that all of the targets with respect to the Company's
"Performance Test

                                       25
<PAGE>
 
Earnings" (as defined in the Warrants and in Section 1.3 hereof) have been met,
and all outstanding Preferred Stock held by other Holders of Preferred Stock
shall likewise be deemed converted.

          9.2  In the event of an Issuance, the Company shall deliver to the
Investor a written notice describing such Issuance, specifying the Investor's
pro rata share and stating the purchase price and other terms of such Issuance
(the "Option Notice"). For a period of 45 days from the receipt of the Option
Notice, the Investor shall have the right to elect, by written notice to the
Company, to purchase all or any portion of its pro rata share of such
securities.

     X.   Participation Rights.
          -------------------- 

          10.1 In addition to and not in limitation of the provisions of the
Shareholders' Agreement, the Founder hereby agrees that until the first to occur
of (a) the Investor no longer owning the Minimum Stock Amount or (b) the
consummation of a Qualifying Public Offering, he shall not sell any of the
shares of the capital stock of the Company held by him, unless such sale is in
accordance with the terms and conditions of this Section 10.

          10.2 Until the consummation of a Qualifying Public Offering, in the
event that the Founder desires to sell some or all of the shares of the capital
stock of the Company held by him (the "Offered Shares") in a private transaction
then the Founder shall obtain a written offer (the "Offer") to purchase such
Offered Shares solely for cash to be paid in full at the closing of each such
transaction, and shall forward a copy of the Offer to the Company and to the
Investor.

          10.3 If, within 30 days of receipt of the offer, the Company notifies
the Founder that it will purchase all of the Offered Shares, then the Founder
shall sell such shares to the Company upon the terms and conditions of the
Offer.

          10.4 If the Company declines to purchase all or any portion of the
Offered Shares in accordance with Section 10.3 above, it shall promptly notify
the Investor of such decision. If, within 30 days of receipt of such notice, the
Investor notifies the Founder that it will purchase all or any portion of the
remaining Offered Shares, then the Founder shall sell such shares to the
Investor upon the terms and conditions of the Offer.

          10.5 If, after giving effect to Sections 10.3 and 10.4 above, the
Company and the Investor fail to purchase all of the Offered Shares, then the
Founder shall be entitled to sell such shares on the terms set forth in the
Offer for a period of 30 days, commencing upon the expiration of the 30-day
period referred to in Section 10.4 above, subject to the provisions of Section
10.6 below.

          10.6 If, after giving effect to Sections 10.3 and 10.4 above, the
Company and the Investor do not agree to purchase all of the Offered Shares,
then the Founder shall use Founder's best efforts to interest the offeror (the
"Offeror") in purchasing such shares as the Investor gives notice that it
desires to sell in such sale (the "Additional Shares"), as well as the Offered
Shares. If the Offeror does not wish to purchase the full amount of the
Additional Shares, then the Investor shall be entitled to sell in the
transaction up to that number of the Additional Shares which, when divided by
the total number of Additional Shares as to which the Investor has given notice
that it desires to sell in the transaction, would be equal to the number of

                                       26
<PAGE>
 
shares which the Offeror has agreed to purchase, divided by the aggregate number
of shares which the Founder and the Investor sought to sell to the Offeror.

          10.7   Other than as set forth above, without the prior written
consent of the Investor, the Founder may not make any transfer of such Founder's
shares of the capital stock of the Company in any transaction not permitted by
the Shareholders' Agreement.

     XI.  Events of Default.
          ----------------- 

          Each of the following shall constitute an Event of Default under this
Agreement:

          11.1   Default on Payments to the Investor. The failure of the Company
                 -----------------------------------
to make (a) within ten days of the date when due, any principal or interest
payment on any Note, any dividend payment upon the Preferred Stock on the date
when due, or any other payment required to be made on the date when due (whether
under the terms of the Notes, the Preferred Stock or the Amendment) in
connection with the redemption of the Preferred Stock or under the terms of the
Notes, or (b) failure of the Company to make any other payment upon any other
note, guaranty or obligation of the Company to the Investor or held by the
Investor, or required hereunder, within 30 days after written notice from the
Investor to the Company; regardless of whether any such failure to make the
payments described in (a) and (b) above is due to a legal inability or
incapacity of the Company to make any such payments.

          11.2   Information, Representations and Warranties. Any information
                 -------------------------------------------                  
furnished or representation or warranty made or given by the Company herein
shall prove to have been untrue when made or given in any material respect or
shall have omitted to state a material fact respecting the matters set forth
therein necessary to make the matters set forth therein not misleading.

          11.3   Covenants and Agreements. The failure of the Company to
                 ------------------------                                
observe, perform or abide by any other covenant, warranty, agreement or
provision of this Agreement, the Amendment, the Notes, the Warrants, the
Preferred Stock, or any of the documents executed by the Company in connection
herewith or therewith or referred to herein or therein, which failure is not
cured to the Investor's reasonable satisfaction within 30 days (the "Cure
Period") after written notice from the Investor to the Company of its
occurrence; provided, however, that no Event of Default shall be considered to
            --------- -------                                                 
have occurred if the failure is not the failure to pay money and is of such a
nature that it reasonably cannot be cured within the Cure Period, but if it is
curable and the Company in good faith begins efforts to cure it within the Cure
Period and continues diligently to do so, the Company shall have an additional
30 days from the date on which the Cure Period ends to effect the cure. If the
failure continues after the expiration of such additional 30 day period,
regardless whether such failure might be curable at some time beyond such
additional 30 day period, such failure shall nevertheless be considered an Event
of Default.

          11.4   Default on Other Obligations. The occurrence of a material
                 ----------------------------                               
default following the expiration of any applicable cure period, if any, in any
material obligation of the Company or any violation of law or refusal of
regulatory permission which has a material adverse effect on the Company's
operations.

<PAGE>
 
          11.5   Certain Events As To The Company. The Company or any of its
                 --------------------------------                            
material subsidiaries shall (A) admit in writing its inability to pay its debts
generally as they become due; (B) file a petition or answer or consent seeking
relief under the Federal Bankruptcy Code, as now constituted or hereafter
amended, or any other applicable federal or state bankruptcy or insolvency law
or other similar law, not discharged or vacated or set aside or stayed within 45
days; (C) consent to the institution of proceedings under any law referenced in
(B) above, not discharged or vacated or set aside or stayed within 45 days, or
to the filing of any such petition, not discharged or vacated or set aside or
stayed within 45 days or to the appointment or taking possession of a receiver,
liquidator, assignee, trustee, custodian (or other similar official) of the
Company or any subsidiary or of any substantial part of their property; (D) fail
generally to pay its debts as such debts become due, or take corporate action in
furtherance of any such action; (E) make an assignment for the benefit of its
creditors; or (F) fail to meet any of its material monetary obligations with the
exception of trade payables, in the amounts and for the periods set forth on
Schedule 2.2 attached hereto; provided, however, that no Event of Default shall
- -------------                 --------  -------                                
be considered to have occurred under subsection 11.5(F) if the failure to meet
such material monetary obligations is due to a good faith dispute between such
parties, which dispute shall continue for no more than 30 days; provided
                                                                --------
further, that upon the expiration of such 30 day period (the "Expiration Date"),
- -------                                                                         
the Company shall have, upon notice to the Investor an additional 30 day period
to resolve the dispute. If the dispute is not resolved after the expiration of
such additional 30 day period, regardless whether such dispute may be resolved
at some time beyond such additional 30 day period, such failure under subsection
11.5(F) shall nevertheless be considered an Event of Default.

          11.6   Certain Events As To The Founder. The Founder dies, is
                 --------------------------------                       
disabled for a period in excess of 120 days during which the Founder is unable
to perform his duties as an officer of the Company for a full eight hour day
(the "disability" of the Founder), terminates his employment with the Company or
has his employment terminated by the Company.

     XII. Rights of Investor Upon Default.
          ------------------------------- 

          12.1   Rights on Default. If there shall occur and be continuing an
                 -----------------                                            
Event of Default as defined in the foregoing Section 11, the Investor, or if
there are then Holders of Preferred Stock, the Holders of at least 75% of the
Preferred Stock may, by written notice to the Company, declare the Company to be
in default hereunder, whereupon: (i) if the Investor or the Holders of at least
75% of the Preferred Stock, as applicable, so specifies in such notice, any
Notes then outstanding, the balance of all accrued dividends upon the Preferred
Stock, and all other indebtedness of the Company to the Investor now or
hereafter incurred, shall become immediately due and payable without further
demand, presentation or notice of any kind; and (ii) the Founder hereby agrees
that, at such time, he shall vote his shares in such a manner and take such
actions as may be necessary or advisable, in the reasonable opinion of the
Investor or the Holders of at least 75% of the Preferred Stock, to best ensure
the repayment of the Notes and payment of all such accrued dividends upon the
Preferred Stock and repayment of all such other indebtedness to the Investor.

          12.2   Additional Rights. The Investor shall have such additional
                 -----------------                                          
rights and remedies as are contained herein, in the Notes, the Warrants, the
Preferred Stock, the Amendment, or in any other documents and agreements
delivered or given in connection

                                       28
<PAGE>
 
herewith, and all rights which it might have at law or equity, all of which
rights and remedies shall be cumulative.

     XIII.  Further Assurance. The Company and the Investor agree to execute
            -----------------                                                
and deliver all such other instruments and take all such other actions as any
party may reasonably request from time to time before or after the Initial or
Subsequent Closing Date and without payment of further consideration, in order

                                  BACKGROUND
                                  ----------

          The Company is seeking to raise up to an aggregate of $3,000,000 in
cash in order to carry on and expand its business and to acquire rights to
certain intellectual property by entering into the License and Development

with Intel Corporation, ("INTEL"), pursuant to which the Company has agreed to
issue to Middlefield Ventures, Inc. ("MIDDLEFIELD") promissory notes convertible
into 1.2 million shares of a new Class of the Company's Convertible Preferred
Stock, and the Purchasers are willing to provide such funds and such
intellectual property rights by purchasing securities of the Company on the
terms contained or referred to herein (the "FINANCING").  In connection with the

("NOTES"). Each Purchaser desires to purchase that aggregate amount of Notes

designations, powers, preferences and other rights set forth in the Company's

means the shares of Class C Preferred Stock issuable upon conversion of the
Notes, the term "CONVERSION SHARES" means the shares of Common Stock issuable
upon conversion of the Preferred Shares and the term "SECURITIES" means the
Notes, the Preferred Shares and the Conversion Shares.

          1.2  PURCHASE AND SALE. Subject to the terms and conditions of this
Agreement, the Company hereby issues and sells to each Purchaser, and each
Purchaser hereby purchases from the Company, the aggregate amount of Notes set

hereby pays the Company the Purchase Price set forth on the Signature Page (the

Transaction Documents, or the consummation of the transactions contemplated
hereby and thereby, contains or will contain any untrue statement of a material
fact or omits or will omit to state a material fact required to be stated in
order to make the statement, in light of the circumstances in which it is made,
not misleading.

     4. REPRESENTATIONS AND WARRANTIES OF PURCHASERS AND RESTRICTIONS ON
TRANSFER.  Each Purchaser represents and warrants to the Company solely with
respect to such Purchaser as follows:

          4.1  LEGAL POWER. Each Purchaser has the requisite individual,
corporate, partnership, trust or fiduciary power, as applicable, and is
authorized, if such Purchaser is a corporation, partnership or trust, to enter
into this Agreement, to purchase the Securities and to carry out and perform its
obligations under the terms of this Agreement.

          4.2  INVESTMENT. The Purchaser (i) is acquiring the Notes, (ii) upon
conversion of the Notes, will acquire the applicable Preferred Shares then
issuable, and (iii) upon conversion of the Preferred Shares will acquire the
applicable Conversion Shares then issuable, 

                                      19
<PAGE>
 
for investment for its own account and not with a view to, or for resale in
connection with, any distribution of the Securities. The Purchaser understands
that the Securities have not been registered under the Securities Act, or under
any state securities or "Blue Sky" laws, and, as a result, are subject to
substantial restrictions on transfer. The Purchaser acknowledges that the
Securities must be held indefinitely unless subsequently registered under the
Securities Act and any applicable state securities or "Blue Sky" laws, or
exemptions from registration under the Securities Act and such laws are
available; provided, however, that by making the representations herein, the
Purchaser does not agree to hold any of the Securities for any minimum or other
specific term and reserves the right to dispose of the Securities at any time in
accordance with or pursuant to a registration statement or an exemption from
registration under the Securities Act and any applicable state securities or
"Blue Sky" laws.

          4.3  DUE EXECUTION. This Agreement has been duly executed and
delivered by such Purchaser and constitutes a valid and legally binding
obligation of such Purchaser, enforceable in accordance with its terms, subject,
as to enforcement, to bankruptcy, insolvency, reorganization and other laws of
general applicability relating to or affecting creditors rights and to general
equity principles. 

          4.4  STATUS OF PURCHASER. The Purchaser is an "accredited investor,"
as that term is defined in Rule 501(a) of Regulation D under the Securities Act.

          4.5  LEGENDS. The Purchasers understand that the certificates or other
instruments representing the Notes and the Preferred Shares and, until such time
as the sale of the Conversion Shares have been registered under the Securities
Act, the stock certificates representing the Conversion Shares, except as set
forth below, shall bear a restrictive legend in substantially the following
form:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
          ANY STATE SECURITIES LAWS AND MAY NOT BE TRANSFERRED IN THE
          ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER
          SUCH ACT AND SUCH LAWS.

The legend set forth above shall be removed and the Company shall issue a
certificate or other instrument without such legend to the holder of the
Securities upon which it is stamped if, unless otherwise required by state
securities laws, (i) such Securities are registered for sale under the
Securities Act, (ii) in connection with a sale transaction, such holder provides
the Company with an opinion of counsel, in a form reasonably acceptable to the
Company's counsel, to the effect that a public sale, assignment or transfer of
such Securities may be made without registration under the Securities Act, or
(iii) such holder provides the Company with an opinion of counsel, in a form
reasonably acceptable to the Company's counsel, that such Securities can be sold
pursuant to Rule 144(k) promulgated under the Securities Act (or a successor
rule thereto) ("RULE 144").  The Purchasers acknowledge, covenant and agree to
sell the Securities represented by a certificate(s) or other instrument(s) from
which the legend has been removed, only pursuant to (i) a registration statement
effective under the Securities Act, or (ii) advice of counsel that such sale is
exempt from registration required by Section 5 of the Securities Act.

     5.   CONTINUATION AND SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties contained herein shall survive as to each
Purchaser the consummation of the transactions provided for in the Transaction
Documents and shall not terminate. No such representation or warranty shall be
deemed to have been waived, affected or impaired by any investigation made by
any person or persons.

     6.   AFFIRMATIVE COVENANTS OF THE COMPANY. The Company hereby covenants to
comply with the following affirmative covenants, unless waived by the holders of
a majority in interest of the Notes or the Class C Preferred Stock, as
applicable, then outstanding, until the closing of an underwritten initial
public offering of any of the Company's securities under the Securities Act (or
any successor statute), yielding gross proceeds to the Company of at least
$20,000,000 (the "CLASS C PERIOD").

          6.1  FINANCIAL STATEMENTS. The Company shall furnish to the Purchasers
the following financial statements, reports and other documents, such financial
statements to be prepared in accordance with generally accepted accounting
principles consistently applied, certified by the Company's chief executive or
financial officer:

               (a)  as soon as available, and in any event within 90 days after
          the end of each fiscal year of the Company, a consolidated balance
          sheet of the Company and its subsidiaries as of the end of such fiscal
          year and related consolidated statements of operations, shareholders'
          equity and cash flows for such fiscal year, all in reasonable detail
          and setting forth in comparative form the figures as of the end of and
          for the previous fiscal year, which consolidated financial statements
          shall have been audited, in accordance with U.S. generally accepted
          accounting principles (GAAP) and shall be accompanied by an
          unqualified opinion addressed to the Company from "Big Six"
          independent auditors or other independent auditors that are reasonably
          satisfactory to the Board of Directors of the Company, together with a
          copy of such auditors' letter to Company's management;

               (b)  as soon as available, and in any event within 30 days after
          the end of each month for such month and for the year to date, an
          unaudited consolidated balance sheet and unaudited consolidated
          statements of operations, shareholders' equity and cash flows,
          together with a comparison of such financial statements with the
          budget of the Company for such period which financial statements shall
          be prepared in accordance with GAAP, consistently applied, except they
          may not contain full footnote disclosures and may be subject to normal
          year-end adjustments for recurring accruals; and

               (c)  as soon as available, and in any event at least 30 days
          prior to the end of each fiscal year of the Company, an annual budget
          and business plan of the Company and its subsidiaries for the
          subsequent fiscal year, which budget and business plan shall include a
          monthly breakdown of financial statements, which breakdown shall
          include the underlying assumptions and a brief qualitative description
          of the Company's plan by the Company's Chief Executive Officer in
          support of such budget and business plan, which also shall have been
          approved

                                      21
<PAGE>
 
          and accepted by the Board of Directors of the Company. If during the
          course of operations for any such month it becomes apparent that
          deviations from such financial statements, budget and business plan
          have occurred, the Company shall submit to its Board of Directors a
          statement of such deviation within five business days from the date of
          the Company's knowledge of such deviation (the "STATEMENT"). The
          Statement shall detail the manner in which a new financial projection
          deviates from the annual business plan and the reason therefor. The
          Board of Directors shall have the right to ask questions or request
          any other reasonable additional information with respect to the
          Statement. Any and all subsequent deviations from such financial
          statements shall be resubmitted to the Board of Directors of the
          Company for approval and acceptance or for required further revision
          until such approval and acceptance is obtained.

               (d)  Each of the financial statements referred to in subsections
          (a)- (c) above shall present fairly in all material respects the
          consolidated financial condition, results of operations and cash flows
          of the Company and its subsidiaries in accordance with GAAP applied on
          a consistent basis as of the dates and throughout the periods set
          forth therein, subject in the case of the unaudited financial
          statements to changes resulting from normal year-end adjustments for
          recurring accruals (none of which would, alone or in the aggregate, be
          materially adverse to the business, operations, assets, Properties,
          liabilities, financial condition, results of operations of the Company
          and its subsidiaries taken as a whole).

          The Company shall, upon request, prepare and deliver each of the
foregoing financial statements in such format, and by such electronic or other
means of transmission, as any Purchaser may reasonably request including a
quarterly financial summary, executed by the Company's chief financial officer,
within 30 days of end of any such quarter.

          6.2  CONFIDENTIALITY AND NONDISCLOSURE.

               (a)  The terms and conditions of the Transaction Documents and
          the License Agreement (collectively, the "Financing Agreements"),
          including their existence, shall be considered confidential
          information to Intel and the Company and shall not be disclosed by any
          party hereto to any third party (other than to the existing
          shareholders of the Company and members of the Company's Board of
          Directors) except in accordance with the provisions set forth below.

               (b)  Within sixty (60) days of the Closing, the Company may issue
          a press release disclosing that Intel has invested in the Company;
          provided that the release does not disclose any of the terms and
          conditions of the Financing Agreements (the "Financing Terms") and the
          final form of the press release is approved in advance in writing by
          Intel. No other announcement regarding Intel's investment in the
          Company in a press release, conference, advertisement, announcement,
          professional or trade publication, mass marketing materials or
          otherwise to the general public may be made without Intel's prior
          written consent.

                                      22
<PAGE>
 
               (c)  Notwithstanding the foregoing, (i) any party may disclose
          any of the Financing Terms, including Intel's investment in the
          Company, to its current or bona fide prospective investors, employees,
          investment bankers, lenders, accountants and attorneys; (ii) any party
          may disclose (other than in a press release or other public
          announcement described in subsection (b)) solely the fact that the
          Investors are investors in the Company to any third parties without
          the requirement for the consent of any other party or nondisclosure
          obligations; and (iii) Intel may disclose its investment in the
          Company and the Financing Terms to third parties or to the public at
          its sole discretion and, if it does so, the other parties hereto shall
          have the right to disclose to third parties any such information
          disclosed in a press release or other public announcement by Intel.

               (d)  In the event that any party is requested or becomes legally
          compelled (including without limitation, pursuant to securities laws
          and regulations) to disclose the existence of the Financing Agreements
          or any of the Financing Terms hereof in contravention of the
          provisions of this Section 6.2, such party (the "Disclosing Party")
          shall provide the other parties (the "Non-Disclosing Parties") with
          prompt written notice of that fact so that the appropriate party may
          seek (with the cooperation and reasonable efforts of the other
          parties) a protective order, confidential treatment or other
          appropriate remedy.  In such event, the Disclosing Party shall furnish
          only that portion of the information which counsel to the Company has
          advised is legally required and shall exercise reasonable efforts to
          obtain reliable assurance that confidential treatment will be accorded
          such information to the extent reasonably requested by any Non-
          Disclosing Party.

               (e)  The provisions of this Section 6.2 shall be in addition to,
          and not in substitution for, the provisions of any separate
          nondisclosure agreement executed by any of the parties hereto with
          respect to the transactions contemplated hereby. Additional
          disclosures and exchange of confidential information between the
          Company and Intel (including without limitation, any exchanges of
          information with any Intel board observer) shall be governed by the
          terms of the Corporate Non-Disclosure Agreement No. 85625, dated
          December 18, 1996, executed by the Company and Intel, and any
          Confidential Information Transmittal Records ("CITR") provided in
          connection therewith.

          6.3  ADDITIONAL INFORMATION.

               (a)  The Company shall, as promptly as possible (but, in any
          event, within ten days) after obtaining knowledge of the occurrence of
          any receipt of notice of any default or event of default, any default
          under any material agreement to which it or any of its subsidiaries is
          a party, or any other material adverse development or event, furnish
          Purchasers with a detailed written notice of such default or event and
          the proposed response of Company management.

          before any court or governmental agency, commission, board, bureau,
          department or instrumentality, domestic or foreign, affecting the
          Company or its subsidiaries.

               (c)  The Company shall promptly furnish the Purchasers with all

          taken by the shareholders and/or directors of the Company or its
          subsidiaries.

               (d)  The Company shall, as promptly as possible (but, in any
          event, within ten days) after sending, making available, or filing the
          same, furnish the Purchasers with all reports and financial statements
          that the Company shall send or make available to the shareholders or
          the directors of the Company.

          otherwise have a significant effect on the Company's or the
          subsidiary's business prospects or financial condition or on the
          Purchasers' investment in the Company.

               (f)  The Company shall furnish the Purchasers with such other

          request.

               (g)  The Purchasers agree not to disclose to third parties any
          information concerning the Company which is furnished to the

          required by law, legal process or its fiduciary duty to report
          financial and business information to its partners, shareholders,
          directors or affiliates and to such other persons as the Purchasers,

          such confidentiality of the confidential information.  The term
          "confidential information" does not include information which (i) was

                          CONVERTIBLE PROMISSORY NOTE
                          ---------------------------


$4,716,00 - Principal Amount Issue Date - April 27, 1999



FOR VALUE RECEIVED, Quadrant International, Inc., a Pennsylvania corporation
(the "Company"), hereby promises to pay to the order of Middlefield Ventures,
Inc. (the "Lender"), in accordance with the terms hereof, the principal sum of
Four Million Seven Hundred Sixteen Thousand Dollars ($4,716,000), with no
interest thereon. The Lender may at any time upon written notice to the Company
demand repayment in full of all outstanding principal hereunder. Principal shall
be due and payable in full upon the earlier of Lender's demand or on April 27,
2004, the fifth anniversary of the issue date of this Note.

All payments shall be made in lawful money of the United States of America at
the principal office of the Company, or at such other place as the holder hereof
may from time to time designate in writing to the Company. This Note may be
prepaid or any demand for payment hereof by Lender may be satisfied by the
transfer to Lender by Escrow Agent (as defined in that certain Convertible
Promissory Note Purchase Agreement of even date herewith between the Company and
the Lender (the "Note Purchase Agreement")) of the outstanding principal
hereunder and any income earned thereon pursuant to that certain Escrow
Agreement of even date herewith among the Company, the Lender and Escrow Agent.
In addition to any right of payment under the Escrow Agreement, Lender will have
full recourse against any tangible or intangible assets of the Company and may
pursue any legal or equitable remedies that are available.

The principal amount of this Note automatically will convert into Class C
Convertible Preferred Stock ("Class C Preferred Stock") of the Company upon the
first business day following the Effective Date (as defined in the Note Purchase
Agreement) (the "Automatic Conversion Date"). On such date, subject to the
conditions set forth herein and in the Escrow Agreement, this Note shall be
deemed cancelled and the Lender shall receive shares of Class C Preferred Stock,
as provided below.

The rights, preferences and privileges of the Class C Preferred Stock shall be
as set forth in the Articles, that certain Registration Rights Agreement between
the Company, the Lenders and the other parties therein dated as of the date
hereof and that certain Amended and Restated Shareholders' Agreement between the
Company, the Lenders and the other parties therein dated as of the date hereof.

On the Effective Date, the Company shall deliver written notice to the Lender,
notifying the Lender of the Automatic Conversion Date and the number of Shares
Lender will be entitled to receive upon conversion of this Note into Class C
Preferred Stock (the "Conversion Shares"). The initial conversion

1 of 4
<PAGE>
 
price shall be $1.43 per share (the "Conversion Price"). The number of shares
issuable upon conversion of this Note shall be determined by dividing the
principal amount due and payable hereunder by the Conversion Price in effect on
the Automatic Conversion Date. Lender promptly shall give written notice to the
Company regarding the name or names in which the Conversion Shares shall be
issued upon conversion of this Note if different from the Lender. If the Company
does not receive such notice prior to the Automatic Conversion Date, this Note
will be converted into Conversion Shares held in Lender's name. Such conversion
will take place on the Automatic Conversion Date at which time (i) the Company
will issue to the Lender or its designee certificates representing the
Conversion Shares to which it is entitled and (ii) Lender shall surrender the
Note, duly endorsed, to the Company.

The Company shall reserve, at all times prior to conversion or repayment in full
of this Note, such securities as Lender is entitled to receive upon conversion
of this Note. Prior to the issuance of any such securities, the Company will
amend its Articles of Incorporation to ensure that it has authorized the
quantity of such securities that are issuable upon conversion of this Note (and
the quantity of Common Stock which are issuable upon conversion of such
securities).

Upon conversion of this Note, the Company shall issue the Conversion Shares to
the Lender or his designees, provided that the Company shall not issue any
fractional Conversion Shares. In lieu of the Company issuing any fractional
Conversion Shares to the Lender upon the conversion of this Note, the Company
shall pay to the Lender the unconverted amount of the Note, such payment to be
in the form of a Company check payable to the Lender. The Company shall deliver
to the Lender or his designees a certificate or certificates representing such
Conversion Shares upon surrender of this Note by the Lender. Such conversion
shall be deemed to have been made on the Automatic Conversion Date, and the
person or persons entitled to the Conversion Shares upon such conversion shall
be treated for all purposes as the record holder or holders of such Conversion
Shares as of such Automatic Conversion Date. Upon conversion of this Note, the
Company shall be forever released from all its obligations and liabilities under
this Note.

This Note shall be governed by and construed in accordance with the laws of the
State of California as applied to agreements among California residents entered
into and to be performed entirely within California, without respect to State of
California choice of law provisions.

The Company hereby agrees, subject only to any limitation imposed by applicable
law, to pay all expenses, including, without limitation, reasonable attorneys'
fees and legal expenses, incurred by the holder of this Note in endeavoring to
collect any amounts payable hereunder which are not paid when due, whether by
declaration or otherwise.

For purposes of this Note, a "Regulatory Problem" means any set of facts or
circumstances wherein it has been asserted by any governmental regulatory agency
that the Lender is not entitled to hold, or exercise any significant right with
respect to, the equity securities of the Company then held by the Lender. If
Lender determines that it has a Regulatory Problem, the Lender will so notify
the Company as soon as practicable in writing. After giving such notice, the
Lender will have the right to transfer this Note and the Company will take all
such actions as are reasonably requested by the Lender in order to (i)
effectuate and facilitate the transfer by the Lender of this Note to any person
designated by the Lender, in good faith, who must be acceptable the Company in
the reasonable and good faith judgment of the Company's Board of Directors, and
(ii) amend, and use its reasonable efforts to cause other relevant parties,
including without limitation the Company's shareholders, to take such actions as
are legally required in order to effectuate and reflect the foregoing.

Notwithstanding the provisions set forth above, the entire unpaid principal
amount of this Note, together with all accrued but unpaid interest to date,
shall become immediately due and payable upon the occurrence of any of the
following events:

          (a) The insolvency of the Company, the commission of any act of
          bankruptcy by the Company, the execution by the Company of a general
          assignment for the benefit of creditors, the filing by or against the
          Company of any petition in bankruptcy or any petition for relief under
          the provisions of the Federal Bankruptcy Act or any other state or
          federal 


2 of 4
<PAGE>
 
          law for the relief of debtors and the continuation of such petition
          without dismissal for a period of twenty (20) days or more, the
          appointment of a receiver or trustee to take possession of any
          property or assets of the Company, or the attachment of or execution
          against any property or assets of the Company; or

          (b) The merger or consolidation of the Company with any other entity,
          a sale of substantially all of the Company's assets to a third party
          or any similar transaction.

This Note shall be binding upon and inure to the benefit of the Lender and its
successors and assigns.

The Company hereby waives presentment, demand, protest, notice of dishonor,
diligence and all other notices, any release or discharge arising from any
extension of time, discharge of a prior party, release of any or all of any
security given from time to time for this Note, or other cause of release or
discharge other than actual payment in full hereof.

Lender shall not be deemed, by any act or omission, to have waived any of its
rights or remedies hereunder unless such waiver is in writing and signed by
Lender and then only to the extent specifically set forth in such writing. Any
waiver with reference to one event shall not be construed as continuing or as a
bar to or waiver of any right or remedy as to a subsequent event. No delay or
omission of Lender to exercise any right, whether before or after a default
hereunder, shall impair any such right or shall be construed to be a waiver of
any right or default, and the acceptance at any time by Lender of any past due
amount shall not be deemed to be a waiver of the right to required prompt
payment when due of any other amounts then or thereafter due and payable.

Time is of the essence hereof. Upon any default hereunder, Lender may exercise
all rights and remedies provided for herein and by law or equity, including, but
not limited to, the right to immediate payment in full of this Note.

The remedies of Lender as provided herein, or any one or more of them, or in law
or in equity, shall be cumulative and concurrent, and may be pursued singularly,
successively or together at Lender's sole discretion, and may be exercised as
often as occasion therefor shall occur.

It is expressly agreed that if suit is brought to collect or interpret this Note
or any part hereof or to enforce or protect any rights conferred upon Lender by
this Note or any other document evidencing or securing this Note, then the
Company agrees to pay all costs, including attorney's fees, incurred by Lender.

This Note shall be governed by and construed in accordance with laws of the
State of California applicable to contracts wholly made and preformed in the
State of California.

               (ii) file such registration within 30 days of the mailing of such
     notice by the Company in accordance hereof and cause such registration to
     be effective as soon as practicable under the Act of all Registrable
     Securities which the Holders request to be registered, subject to the
     limitations of subsection 1.2(b).

                                       2
<PAGE>
 
          (b)  If the Holders initiating the registration request hereunder
("Initiating Holders") intend to distribute the Registrable Securities covered
by their request by means of an underwriting, they shall so advise the Company
as a part of their request made pursuant to subsection 1.2(a) and the Company
shall include such information in the written notice referred to in subsection
1.2(a). The underwriter will be selected by the Company and shall be reasonably
acceptable to a majority in interest of the Initiating Holders. In such event,
the right of any Holder to include such Holder's Registrable Securities in such
registration shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting (unless otherwise mutually agreed by a majority in interest of the
Initiating Holders and such Holder) to the extent provided herein. All Holders
proposing to distribute their securities through such underwriting shall
(together with the Company as provided in subsection 1.4(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting. Notwithstanding any other provision of this
Section 1.2, if the underwriter advises the Initiating Holders in writing that
marketing factors require a limitation of the number of shares to be
underwritten, then the Initiating Holders shall so advise all Holders of
Registrable Securities which would otherwise be underwritten pursuant hereto,
and the number of shares of Registrable Securities that may be included in the
underwriting shall be allocated among all Holders thereof, including the
Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each Holder; provided, however,
that the number of shares of Registrable Securities issued or issuable upon
conversion of the Class A Preferred Stock, the Class B Preferred Stock and the
Class C Preferred Stock of the Company to be included in such underwriting shall
not be reduced unless all other securities are first entirely excluded from the
underwriting.

          (c)  The Company may include in a registration requested under Section
1.2(a) any additional authorized shares of the Common Stock of the Company,
whether or not issued, for sale by the Company; provided, however, that such
shares shall not be included to the extent that the Holders of a majority of the
shares of Registrable Securities held by the Investors included therein
determine in good faith that the inclusion of such shares will interfere with
the successful marketing of the shares of Registrable Securities to be included
therein; and provided, further, that if the number of shares to be so included
equals or exceeds the number of shares of Registrable Securities included
therein by the holders of Registrable Securities, such registration shall be
deemed to be a registration pursuant to Section 1.3 hereof.

          (d)  Notwithstanding the foregoing, if the Company shall furnish to
Holders requesting a registration statement pursuant to this Section 1.2 or
Section 1.12, a certificate of the Company signed by the Chief Executive Officer
of the Company stating that in the good faith judgment of the Board of Directors
of the Company, the filing of such registration statement would (A) interfere
with or affect the negotiation or completion of any material transaction that is
being contemplated by the Company or (B) involve initial or continuing
disclosure obligations materially adverse to the best interests of the Company's
shareholders, and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer taking action
with respect to such filing for a period of not more than sixty (60) days after
receipt of the request of the Initiating Holders; provided, however, that the
Company may not utilize this right more than once in any twelve-month period,
and the time periods referred to in 

                                       3
<PAGE>
 
this Section 1.2 or Section 1.12 shall be extended for an additional number of
business days during which the rights to sell shares were suspended.

          (e)  In addition, the Company shall not be obligated to effect,
or to take any action to effect, any registration pursuant to this Section 1.2:

               (i)  After the Company has effected two registrations pursuant to
     this Section 1.2 and such registrations have been declared or ordered
     effective; or

               (ii) During the period ending on a date six (6) months after the
     effective date of a registration subject to Sections 1.2 or 1.3 hereof.

          1.3  Company Registration. If (but without any obligation to do so)
               -------------------- 
the Company proposes to register (including for this purpose a registration
effected by the Company for shareholders other than the Holders) any of its
stock or other securities under the Act in connection with the public offering
of such securities solely for cash (other than a registration relating solely to
the sale of securities to participants in a Company stock plan, a registration
on any form which does not include substantially the same information as would
be required to be included in a registration statement covering the sale of the
Registrable Securities or a registration in which the only Common Stock being
registered is Common Stock issuable upon conversion of debt securities which are
also being registered or covering only securities proposed to be issued in
exchange for securities or assets of another corporation or an SEC Rule 145
transaction), the Company shall, at such time, promptly give each Holder written
notice of such registration. Upon the written request of each Holder given
within twenty (20) days after mailing of such notice by the Company in
accordance with Section 2.6, the Company shall, subject to the provisions of
Section 1.8, use its best efforts to cause to be registered under the Act all of
the Registrable Securities that each such Holder has requested to be registered.
In no event, however, shall any holder of registration rights be granted
registration rights under this Section 1.3 that are superior to the registration
rights of the Holders without the written consent of the holders of at least 50%
of the Registrable Securities.

          1.4  Obligations of the Company. Whenever required under this Section
               -------------------------- 
1 to effect the registration of any Registrable Securities, the Company shall,
as expeditiously as reasonably possible:

          (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder with respect
to a registration under Sections 1.2 and 1.12, keep such registration statement
effective for the period necessary (but, other than as provided below, in no
event more than nine (9) months) to complete the proposed public offering;
provided, however, that (i) such nine (9)-month period shall be extended for a
period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of
Common Stock (or other securities) of the Company; and (ii) in the case of any
registration of Registrable Securities on Form S-3 which are intended to be
offered on a continuous or delayed basis, such 120-day period shall be extended,
if necessary, but for not more than a period of two (2) years, to keep the
registration statement effective until all such 

                                       4
<PAGE>
 
Registrable Securities are sold, provided that Rule 415, or any successor rule
under the Act, permits an offering on a continuous or delayed basis, and
provided further that applicable rules under the Act governing the obligation to
file a post-effective amendment permit, in lieu of filing a post-effective
amendment which (i) includes any prospectus required by Section 10(a)(3) of the
Act or (ii) reflects facts or events representing a material or fundamental
change in the information set forth in the registration statement, the
incorporation by reference of information required to be included in (i) and
(ii) above to be contained in periodic reports filed pursuant to Section 13 or
15(d) of the 1934 Act in the registration statement.

          (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

          (c)  Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them.

          (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders;
provided that the Company shall not be required in connection therewith or as a
condition thereto to (i) qualify to do business as a foreign corporation or (ii)
to file a general consent to service of process in any such states or
jurisdictions, unless the Company is already subject to service in such
jurisdiction, or (iii) register in any state requiring, as a condition to
registration, escrow or surrender of any Company securities.

          (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

          (f)  Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing. If, in
such event, the Company advises the Holders of the Registrable Securities
covered by such registration statement that the Company considers it appropriate
for the registration statement to be amended, the Holders of such securities
shall suspend any further sales of their registered shares until the Company
advises them that the registration statement has been amended and the Company
has delivered revised prospectuses to the selling Holders (the selling Holders
shall promptly return to the Company all prior prospectuses). The time periods
referred to in this Section 1 shall be extended for an additional number of
business days during which the rights to sell shares was suspended.

                                       5
<PAGE>
 
          (g)  Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed.

          (h)  Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereunder and a CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

          (i)  Furnish, at the request of any Holder requesting registration of
Registrable Securities pursuant to this Section 1, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to this Section 1, if such securities are being
sold through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated such date, from
the independent certified public accountants of the Company, in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of Registrable Securities.

          1.5  Furnish Information. It shall be a condition precedent to the
               ------------------- 
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

          1.6  Expenses of Demand Registration. All expenses, other than
               ------------------------------- 
underwriting discounts and commissions, incurred in connection with
registrations, filings or qualifications pursuant to Section 1.2, including
(without limitation) all registration, filing and qualification fees, printers'
and accounting fees, and fees and disbursements of one counsel for the Holders
shall be borne by the Company; provided, however, that if a registration is
withdrawn at the request of the Holders requesting such registration (other than
as a result of information concerning a material adverse change to the business
or financial condition of the Company which is made known to the Holders after
the date on which such registration was requested) and if the requesting Holders
elect not to have such registration counted as a registration requested under
Section 1.2, the requesting Holders shall pay all of the expenses referred to
above of such registration pro rata in accordance with the number of their
Registrable Securities included in such registration in relation to the number
of shares of the Company and of others which were included in the registration.

          1.7  Expenses of Company Registration. The Company shall bear and pay
               -------------------------------- 
all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations
pursuant to Section 1.3 for each Holder (which right may be assigned as provided
in Section 1.13), including (without limitation) all registration, 

                                       6
<PAGE>
 
filing and qualification fees, printers and accounting fees and fees and
disbursements of one counsel for the Holders relating or apportionable thereto
selected by them, but excluding solely underwriting discounts and commissions
relating to Registrable Securities.

          1.8  Underwriting Requirements. In connection with any offering
               ------------------------- 
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 1.3 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities sold that the
underwriters determine in their sole discretion is compatible with the success
of the offering, then the Company shall be required to include in the offering
only that number of such securities, including Registrable Securities, which the
underwriters determine in their sole discretion will not jeopardize the success
of the offering (the securities so included to be reduced, first, pro rata among
the holders of capital stock in their entirety, if necessary other than the
Holders; second, if necessary, the shares held by Garnick and the Viona
Employees pro rata; third, if necessary, among any other of the Holders other
than the holders of Class A Preferred Stock, Class B Preferred Stock and Class C
Preferred Stock; fourth, if necessary, pro rata among the Holders of the Class A
Preferred Stock, the Class B Preferred Stock and the Class C Preferred Stock of
the Company; next and lastly, if necessary, among the Company's shares requested
by the Company to be registered). For purposes of the preceding parenthetical
concerning apportionment, for any selling shareholder which is a holder of
Registrable Securities and which is a partnership or corporation, the partners,
retired partners and shareholders of such holder, or the estates and family
members of any such partners and retired partners and any trusts for the benefit
of any of the foregoing persons shall be deemed to be a single "selling
shareholder", and any pro-rata reduction with respect to such "selling
shareholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling shareholder," as defined in this sentence.

          1.9  Delay of Registration. No Holder shall have any right to obtain
               --------------------- 
or seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1.

          1.10 Indemnification. In the event any Registrable Securities are
               --------------- 
included in a registration statement under this Section 1:

          (a)  The Company will indemnify and hold harmless each Holder, any
underwriter (as defined in the Act) for such Holder and each person, if any, who
controls such Holder or underwriter within the meaning of the Act or the 1934
Act, against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"): (i) any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, (ii) the omission

                                       7
<PAGE>
 
or alleged omission to state therein a material fact required to be stated
therein, or necessary to make the statements therein not misleading, or (iii)
any violation or alleged violation by the Company of the Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the Act, the
1934 Act or any state securities law; and the Company will pay to each such
Holder, underwriter or controlling person, as incurred, any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity obligations of the Company contained in this subsection
1.10(a) shall not apply (x) to amounts paid in settlement of any such loss,
claim, damage, liability, or action if such settlement is effected without the
consent of the Company (which consent shall not be unreasonably withheld), (y)
in any such case for any such loss, claim, damage, liability, or action to the
extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by any such Holder, underwriter or
controlling person, and (z) with respect to a Violation contained in or with
respect to a preliminary prospectus if a copy of the amended or supplemental
preliminary prospectus, or the final prospectus, shall have been delivered or
sent to such person within the time required by the Act, and the Violation was
corrected in such amended or supplemental preliminary prospectus or final
prospectus.

          (b)  Each selling Holder will indemnify and hold harmless the Company,
each of its directors, each of its officers, each person, if any, who controls
the Company within the meaning of the Act or the 1934 Act, any underwriter, any
other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereto) arise out of or are based upon any Violation, in each case
to the extent (and only to the extent) that such Violation occurs in reliance
upon and in conformity with written information furnished by such Holder
expressly for use in connection with such registration; and each such Holder
will pay any legal or other expenses reasonably incurred by any person intended
to be indemnified pursuant to this subsection 1.10(b), in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement of the Company contained in this
subsection 1.10(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Holder, which consent shall not be unreasonably withheld; and
provided further, the total amount for which any Holder shall be liable shall
not in any event exceed the lesser of (A) aggregate net proceeds received by
such Holder from the sale of Registrable Securities held by such Holder in such
registration and (B) in the event that the underwriter shall require joint and
several liability of the selling Holders, that portion of aggregate losses,
claims, damages, liabilities or expenses indemnified against as is equal to the
proportion of the total number of Registrable Securities being sold by such
Holder to the total number of shares of Common Stock being sold by the Company
and all persons for which shares are registered in such offering; and provided
further, however, that no Holder shall be required to enter into an Underwriting
Agreement that provides for any greater potential liability than as set forth
herein.

                                       8
<PAGE>
 
          (c)  Promptly after receipt by an indemnified party under this Section
1.10 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 1.10, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties (the consent of the indemnified party to such
counsel not to be unreasonably withheld); provided, however, that an indemnified
party (together with all other indemnified parties which may be represented
without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.10, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.10.

          (d)  If the indemnification provided for in this Section 1.10 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

          (e)  Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

          (f)  The obligations of the Company and Holders under this Section
1.10 shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

          1.11 1934 Act. With a view to making available to the Holders the
               -------- 
benefits of Rule 144 promulgated under the Act and any other rule or regulation
of the SEC that may at any time permit a Holder to sell securities of the
Company to the public without registration or pursuant to a registration on Form
S-3, the Company agrees to:

                                       9
<PAGE>
 
          (a)  make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public;

          (b)  take such action, including the voluntary registration of its
Common Stock under Section 12 of the 1934 Act, as is necessary to enable the
Holders to utilize Form S-3 for the sale of their Registrable Securities, such
action to be taken as soon as practicable after the end of the fiscal year in
which the first registration statement filed by the Company for the offering of
its securities to the general public is declared effective;

          (c)  file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

          (d)  furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144 (at any time
after ninety (90) days after the effective date of the first registration
statement filed by the Company), the Act and the 1934 Act (at any time after it
has become subject to such reporting requirements), or that it qualifies as a
registrant whose securities may be resold pursuant to Form S-3 (at any time
after it so qualifies), (ii) a copy of the most recent annual or quarterly
report of the Company and such other reports and documents so filed by the
Company, and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC which permits the
selling of any such securities without registration or pursuant to such form.

          1.12 Form S-3 Registration. In case the Company shall receive from any
               --------------------- 
Holder or Holders holding at least fifty percent (50%) of the Registrable
Securities then outstanding a written request or requests that the Company
effect a registration on Form S-3 and any related qualification or compliance
with respect to all or a part of the Registrable Securities owned by such Holder
or Holders but in no event less than 25% of each of the originally issued Class
B Preferred Stock and the originally issued Series C Preferred Stock, the
Company will:

          (a)  promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders; and

          (b)  effect, as soon as practicable, such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within
fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance, pursuant to this Section 1.12: (1) if
Form S-3 is not available for such offering by the Holders; (2) if the Company
shall furnish to the Holders a certificate signed by the President of the
Company stating that in the good faith judgment of the Board of Directors of the
Company, the filing of such Form S-3 Registration would (A) interfere with or
affect the negotiation or completion of any material transaction that is being
contemplated by the Company or (B) involve initial or 

                                      10
<PAGE>
 
continuing disclosure obligations materially adverse to the best interests of
the Company's shareholders, and it is therefore essential to defer the filing of
such registration statement, in which event the Company shall have the right to
defer the filing of the Form S-3 registration statement for a period of not more
than sixty (60) days after receipt of the request of the Holder or Holders under
this Section 1.12; provided, however, that the Company shall not utilize this
right more than once in any twelve (12) month period; or (3) in any particular
jurisdiction in which the Company would be required to qualify to do business or
to execute a general consent to service of process in effecting such
registration, qualification or compliance.

          (c)  Subject to the foregoing, the Company shall file a registration
statement covering the Registrable Securities and other securities so requested
to be registered as soon as practicable after receipt of the request or requests
of the Holders. All expenses incurred in connection with a registration
requested pursuant to Section 1.12, including (without limitation) all
registration, filing, qualification, printer's and accounting fees and the fees
and disbursements of one counsel for the Holders, but excluding solely any
underwriters' discounts or commissions, shall be borne by the Company.
Registrations effected pursuant to this Section 1.12 shall not be counted as
demands for registration or registrations effected pursuant to Sections 1.2 or
1.3.

          (d)  The Company shall not be obligated to effect any registration
pursuant to this Section 1.12 if the Company delivers to the Holders requesting
registration under this Section 1.12 an opinion, in form and substance
acceptable to such Holders, of counsel satisfactory to such Holders, that the
Registrable Securities so requested to be registered may be sold or transferred
pursuant to Rule 144(k) under the Act.

          1.13 Assignment of Registration Rights. The rights to cause the
               --------------------------------- 
Company to register Registrable Securities pursuant to this Section 1 may be
assigned by a Holder to a transferee or assignee of such securities provided
that the Company is given a written notice at the time of or within a reasonable
time after such transfer or assignment, stating the name and address of the
transferee or assignee and identifying the securities with respect to which such
registration rights are being transferred or assigned, and, provided further,
that the transferee or assignee of such rights assumes the obligations of such
Holder under this Section 1.

          1.14 Limitations on Subsequent Registration Rights. From and after the
               --------------------------------------------- 
date of this Agreement, the Company shall not, without the prior written consent
of the Holders of a majority of the outstanding Registrable Securities, enter
into any agreement with any holder or prospective holder of any securities of
the Company which would allow such holder or prospective holder (a) to include
such securities in any registration filed under Section 1.2 hereof, unless under
the terms of such agreement, such holder or prospective holder may include such
securities in any such registration only to the extent that the inclusion of
such holder's securities will not reduce the amount of the Registrable
Securities of the Holders which is included or (b) to make a demand registration
which could result in such registration statement being declared effective prior
to the earlier of either of the dates set forth in subsection 1.2(a) or within
one hundred twenty (120) days of the effective date of any registration effected
pursuant to Section 1.2.

          1.15 "Market Stand-Off" Agreement. Each Investor and Existing Investor
               ---------------------------- 
hereby agrees that, during the period of duration specified by the Company and
an underwriter of Common Stock or other securities of the Company, following the
effective date of a registration statement of the Company filed under the Act,
it shall not, to the extent requested by the Company and such underwriter,
directly or indirectly sell, offer to sell, contract to sell (including, without
limitation, any short sale), grant any option to purchase or otherwise transfer
or dispose of (other than to donees who agree to be similarly bound) any
securities of the Company held by it at any time during such period except
Common Stock included in such registration; provided, however, that:

          (a)  such agreement shall be applicable as to the period immediately
following the first such registration statement of the Company which covers
Common Stock to be sold on its behalf to the public in an underwritten offering;

          (b)  all officers, directors and founders of the Company, all then
existing two percent or greater shareholders of the Company and all other
persons with registration rights (whether or not pursuant to this Agreement)
enter into similar agreements; and

          (c)  such market stand-off time period shall not exceed one hundred
eighty (180) days.

          In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of each
Investor and Existing Investor (and the shares or securities of every other
person subject to the foregoing restriction) until the end of such period.

          Notwithstanding the foregoing, the obligations described in this
Section 1.15 shall not apply to a registration relating solely to employee
benefit plans on Form S-l or Form S-8 or similar forms which may be promulgated
in the future, or a registration relating solely to a Commission Rule 145
transaction on Form S-4 or similar forms which may be promulgated in the future.

Registrable Securities at any time while the Company either (a) is subject to
periodic reporting pursuant to Section 15(d) of the Exchange Act or (b) has 500
or more shareholders of record, the Company shall register its Common Stock
under Section 12 of the 1934 Act and arrange for its Common Stock to be listed
on a national stock exchange or included for quotation on the Nasdaq National
Market, as requested, and shall keep effective such registration and maintain
such listing or inclusion.

                           1999 STOCK INCENTIVE PLAN
                     -------------------------------------

                                  ARTICLE ONE
                               GENERAL PROVISIONS
                               ------------------

  I.   PURPOSE OF THE PLAN

          This 1999 Stock Incentive Plan is intended to promote the interests of
Divicore Inc., a Delaware corporation, by providing eligible persons with the
opportunity to acquire a proprietary interest, or otherwise increase their
proprietary interest, in the Corporation as an incentive for them to remain in
the service of the Corporation.

          Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

  II.  STRUCTURE OF THE PLAN

          A.  The Plan shall be divided into three separate equity programs:

                    (i)   the Discretionary Option Grant Program under which
     eligible persons may, at the discretion of the Plan Administrator, be
     granted options to purchase shares of Common Stock,

                    (ii)  the Stock Issuance Program under which eligible
     persons may, at the discretion of the Plan Administrator, be issued shares
     of Common Stock directly, either through the immediate purchase of such
     shares or as a bonus for services rendered the Corporation (or any Parent
     or Subsidiary), and

                    (iii) the Automatic Option Grant Program under which
     eligible non-employee Board members shall automatically receive options at
     periodic intervals to purchase shares of Common Stock.

          B.  The provisions of Articles One and Five shall apply to all equity
programs under the Plan and shall govern the interests of all persons under the
Plan.

  III. ADMINISTRATION OF THE PLAN

          A.  The following provisions shall govern the administration of the
Plan:

                    (i)   The Board shall have the authority to administer the
     Discretionary Option Grant and Stock Issuance Programs with respect to
     Section 16 Insiders but may delegate such authority in whole or in part to
     the Primary Committee.
<PAGE>
 
                    (ii)   Administration of the Discretionary Option Grant and
     Stock Issuance Programs with respect to all other persons eligible to
     participate in those programs may, at the Board's discretion, be vested in
     the Primary Committee or a Secondary Committee, or the Board may retain the
     power to administer those programs with respect to all such persons.

                    (iii)  Administration of the Automatic Option Grant Program
     shall be self-executing in accordance with the terms of that program.
     
          B.  Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full power and authority
subject to the provisions of the Plan:

                    (i)    to establish such rules as it may deem appropriate
     for proper administration of the Plan, to make all factual determinations,
     to construe and interpret the provisions of the Plan and the awards
     thereunder and to resolve any and all ambiguities thereunder;

                    (ii)   to determine, with respect to awards made under the
     Discretionary Option Grant and Stock Issuance Programs, which eligible
     persons are to receive such awards, the time or times when such awards are
     to be made, the number of shares to be covered by each such award, the
     vesting schedule (if any) applicable to the award, the status of a granted
     option as either an Incentive Option or a Non-Statutory Option and the
     maximum term for which the option is to remain outstanding;

                    (iii)  to amend, modify or cancel any outstanding award with
     the consent of the holder or accelerate the vesting of such award; and

                    (iv)   to take such other discretionary actions as permitted
     pursuant to the terms of the applicable program. 

Decisions of each Plan Administrator within the scope of its administrative
functions under the Plan shall be final and binding on all parties.

          C.  Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time. The Board may also at any time terminate the functions of
any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

          D.  Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any options or stock issuances under the Plan.

  IV.  ELIGIBILITY

                                       2
<PAGE>
 
          A.  The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

                    (i)     Employees,

                    (ii)    non-employee members of the Board or the board of
     directors of any Parent or Subsidiary, and

                    (iii)   consultants and other independent advisors who
provide services to the Corporation (or any Parent or Subsidiary).

          B.  Only non-employee Board members shall be eligible to participate
in the Automatic Option Grant Program.

     V. STOCK SUBJECT TO THE PLAN

          A.  The stock issuable under the Plan shall be shares of authorized 
but unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market. The maximum number of shares of Common Stock
initially reserved for issuance over the term of the Plan shall not exceed
______________________________ (____________). Such authorized share reserve
consists of (i) the number of shares estimated to be available for issuance, as
of the Plan Effective Date, under the Predecessor Plan as last approved by the
Corporation's stockholders, including the shares subject to the outstanding
options to be incorporated into the Plan and the additional shares which would
otherwise be available for future grant, plus (ii) an increase of approximately
___________________________ (_____________) additional shares.

          B.  The number of shares of Common Stock available for issuance under
the Plan shall automatically increase on the first trading day of each calendar
year during the term of the Plan, beginning with the 2000 calendar year, by an
amount equal to one percent (1%) of the shares of Common Stock outstanding on
the last trading day of the immediately preceding calendar year, but in no event
shall such annual increase exceed _____________________ (__________) shares.

          C.  No one person participating in the Plan may be granted stock
options, separately exercisable stock appreciation rights and direct stock
issuances for more than _____________________ (_________________) shares of
Common Stock in the aggregate per calendar year, beginning with the 1999
calendar year.

          D.  Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plans) shall be
available for subsequent issuance under the Plan to the extent those options
expire, terminate or are cancelled for any reason prior to exercise in full.
Unvested shares issued under the Plan and subsequently repurchased by the
Corporation, at the original exercise or issue price paid per share, pursuant to
the Corporation's repurchase rights under the Plan shall be added back to the
number of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent options
or direct stock issuances under the Plan. However, should the exercise price of
an option under the Plan be paid with shares of Common 

                                       3
<PAGE>
 
Stock or should shares of Common Stock otherwise issuable under the Plan be
withheld by the Corporation in satisfaction of the withholding taxes incurred in
connection with the exercise of an option or the vesting of a stock issuance
under the Plan, then the number of shares of Common Stock available for issuance
under the Plan shall be reduced by the gross number of shares for which the
option is exercised or which vest under the stock issuance, and not by the net
number of shares of Common Stock issued to the holder of such option or stock
issuance. Shares of Common Stock underlying one or more stock appreciation
rights exercised under the Plan shall NOT be available for subsequent issuance.

          E.   If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the maximum number of securities by which the share reserve is to
increase each calendar year pursuant to the automatic share increase provisions
of the Plan, (iii) the number and/or class of securities for which any one
person may be granted options, separately exercisable stock appreciation rights
and direct stock issuances under this Plan per calendar year, (iv) the number
and/or class of securities for which grants are subsequently to be made under
the Automatic Option Grant Program to new and continuing non-employee Board
members, (v) the number and/or class of securities and the exercise price per
share in effect under each outstanding option under the Plan and (vi) the number
and/or class of securities and price per share in effect under each outstanding
option incorporated into this Plan from the Predecessor Plans. Such adjustments
to the outstanding options are to be effected in a manner which shall preclude
the enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

                       DISCRETIONARY OPTION GRANT PROGRAM
                       ----------------------------------

     I.  OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
                                    --------                                  
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   EXERCISE PRICE.
               -------------- 

               1.  The exercise price per share shall be fixed by the Plan
Administrator at the time of the option grant.

               2.  The exercise price shall become immediately due upon exercise
of the option and shall, subject to the provisions of Section II of Article Five
and the documents evidencing the option, be payable in one or more of the
following forms:

                   (i)  in cash or check made payable to the Corporation,

                                       4
<PAGE>
 
                    (ii)    shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

                    (iii)   to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to which
     the Optionee shall concurrently provide irrevocable instructions to (a) a
     Corporation-approved brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Corporation by reason of such exercise and (b) the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   EXERCISE AND TERM OF OPTIONS.  Each option shall be exercisable
               ----------------------------
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option. However, no option shall have a term in excess of ten
(10) years measured from the option grant date.

          C.   CESSATION OF SERVICE.
               -------------------- 

               1.  The following provisions shall govern the exercise of any
options outstanding at the time of the Optionee's cessation of Service or death:

                    (i)     Any option outstanding at the time of the Optionee's
     cessation of Service for any reason shall remain exercisable for such
     period of time thereafter as shall be determined by the Plan Administrator
     and set forth in the documents evidencing the option, but no such option
     shall be exercisable after the expiration of the option term.

                    (ii)    Any option held by the Optionee at the time of death
     may be subsequently exercised by his or her Beneficiary to the extent that
     option is exercisable for one or more vested shares at the time of
     Optionee's death.

                    (iii)   During the applicable post-Service exercise period,
     the option may not be exercised in the aggregate for more than the number
     of vested shares for which the option is exercisable on the date of the
     Optionee's cessation of Service. Upon the expiration of the applicable
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised. However, the option shall,
     immediately upon the Optionee's cessation of Service, terminate and cease
     to be outstanding to the extent the option is not otherwise at that time
     exercisable for vested shares.

                                       5
<PAGE>
 
                    (iv)   Should the Optionee's Service be terminated for
     Misconduct or should the Optionee engage in Misconduct while his or her
     options are outstanding, then all such options shall terminate immediately
     and cease to be outstanding.

               2.   The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding:

                    (i)    to extend the period of time for which the option is
     to remain exercisable following the Optionee's cessation of Service to such
     period of time as the Plan Administrator shall deem appropriate, but in no
     event beyond the expiration of the option term, and/or

                    (ii)   to permit the option to be exercised, during the
     applicable post-Service exercise period, for one or more additional
     installments in which the Optionee would have vested had the Optionee
     continued in Service.

          D.  STOCKHOLDER RIGHTS.  The holder of an option shall have no 
              ------------------            
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.  REPURCHASE RIGHTS.  The Plan Administrator shall have the 
              ----------------- 
discretion to grant options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such repurchase
right shall be exercisable (including the period and procedure for exercise and
the appropriate vesting schedule for the purchased shares) shall be established
by the Plan Administrator and set forth in the document evidencing such
repurchase right.

          F.  LIMITED TRANSFERABILITY OF OPTIONS.  During the lifetime of the
              ----------------------------------                             
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death. Non-Statutory Options shall be
subject to the same restrictions, except that a Non-Statutory Option may, to the
extent permitted by the Plan Administrator, be assigned in whole or in part
during the Optionee's lifetime to one or more members of the Optionee's
immediate family or to a trust in which the Optionee and/or one or more such
family members have more than a fifty percent (50%) of the beneficial interest
or to any other entity in which the Optionee and/or one or more such family
members own more than fifty percent (50%) of the voting interests. The terms
applicable to the assigned portion shall be the same as those in effect for the
option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Plan Administrator may deem appropriate.
Notwithstanding the foregoing, the Optionee may also designate a Beneficiary or
Beneficiaries of his or her outstanding options under this Article Two, and
those options shall, in accordance with such designation, be automatically
transferred to such Beneficiary or Beneficiaries upon Optionee's death while
holding those options. Such Beneficiary or Beneficiaries shall take the
transferred options subject to the all the terms and conditions of the
applicable agreement evidencing each 

                                       6
<PAGE>
 
such transferred option, including (without limitation) the limited time period
during which the option may be exercised following the Optionee's death.

     II.   INCENTIVE OPTIONS

               The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Seven shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall not be subject to the terms of this Section II.
                                 ---                                            

               A.  ELIGIBILITY.  Incentive Options may only be granted to
                   -----------
Employees.

               B.  EXERCISE PRICE.  The exercise price per share shall not be
                   --------------      
less than one hundred percent (100%) of the Fair Market Value per share of
Common Stock on the option grant date.

               C.  DOLLAR LIMITATION.  The aggregate Fair Market Value of the
                   -----------------
shares of Common Stock (determined as of the respective date or dates of grant)
for which one or more options granted to any Employee under the Plan (or any
other option plan of the Corporation or any Parent or Subsidiary) may for the
first time become exercisable as Incentive Options during any one calendar year
shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

               D.  10% STOCKHOLDER.  If any Employee to whom an Incentive Option
                   --------------- 
is granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

     III.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

               A.  Each option outstanding at the time of a Change in Control
but not otherwise fully-vested shall automatically accelerate so that each such
option shall, immediately prior to the effective date of the Change in Control,
become exercisable for all of the shares of Common Stock at the time subject to
that option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock. However, an outstanding option shall not so accelerate
if and to the extent: (i) such option is, in connection with the Change in
Control, assumed by the successor corporation (or parent thereof) or otherwise
continued in full force and effect pursuant to the terms of the Change in
Control, (ii) such option is replaced with a cash incentive program of the
successor corporation which preserves the spread existing at the time of the
Change in Control on the shares of Common Stock for which the option is not
otherwise at that time exercisable and provides for subsequent payout in
accordance with the same vesting schedule applicable to those option shares or
(iii) the acceleration of such option is subject to other limitations imposed by
the Plan Administrator at the time of the option grant.

               B.  All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in 

                                       7
<PAGE>
 
the event of any Change in Control, except to the extent: (i) those repurchase
rights are assigned to the successor corporation (or parent thereof) or
otherwise continue in full force and effect pursuant to the terms of the Change
in Control or (ii) such accelerated vesting is precluded by other limitations
imposed by the Plan Administrator at the time the repurchase right is issued.

          C.  Immediately following the consummation of the Change in Control,
all outstanding options shall terminate and cease to be outstanding, except to
the extent assumed by the successor corporation (or parent thereof) or otherwise
expressly continued in full force and effect pursuant to the terms of the Change
in Control.

          D.  Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted, immediately after such Change in
Control, to apply to the number and class of securities which would have been
issuable to the Optionee in consummation of such Change in Control had the
option been exercised immediately prior to such Change in Control. Appropriate
adjustments to reflect such Change in Control shall also be made to (i) the
exercise price payable per share under each outstanding option, provided the
                                                                -------- 
aggregate exercise price payable for such securities shall remain the same, (ii)
the maximum number and/or class of securities available for issuance over the
remaining term of the Plan and (iii) the maximum number and/or class of
securities for which any one person may be granted options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year.

          E.  The Plan Administrator may at any time provide that one or more
options will automatically accelerate in connection with a Change in Control,
whether or not those options are assumed or otherwise continued in full force
and effect pursuant to the terms of the Change in Control. Any such option shall
accordingly become exercisable, immediately prior to the effective date of such
Change in Control, for all of the shares of Common Stock at the time subject to
that option and may be exercised for any or all of those shares as fully-vested
shares of Common Stock. In addition, the Plan Administrator may at any time
provide that one or more of the Corporation's repurchase rights shall not be
assignable in connection with such Change in Control and shall terminate upon
the consummation of such Change in Control.

          F.  The Plan Administrator may at any time provide that one or more
options will automatically accelerate upon an Involuntary Termination of the
Optionee's Service within a designated period (not to exceed eighteen (18)
months) following the effective date of any Change in Control in which those
options do not otherwise accelerate. Any options so accelerated shall remain
exercisable for fully-vested shares until the expiration or sooner termination
of the option term. In addition, the Plan Administrator may at any time provide
that one or more of the Corporation's repurchase rights shall immediately
terminate upon such Involuntary Termination.

          G.  The Plan Administrator may at any time provide that one or more
options will automatically accelerate in connection with a Hostile Take-Over.
Any such option shall become exercisable, immediately prior to the effective
date of such Hostile Take-Over, for all of the shares of Common Stock at the
time subject to that option and may be exercised for any or all of those shares
as fully-vested shares of Common Stock. In addition, the Plan Administrator may
at any time provide that one or more of the Corporation's repurchase rights
shall terminate automatically upon the consummation of such Hostile Take-Over.
Alternatively, the Plan 

                                       8
<PAGE>
 
Administrator may condition such automatic acceleration and termination upon an
Involuntary Termination of the Optionee's Service within a designated period
(not to exceed eighteen (18) months) following the effective date of such
Hostile Take-Over. Each option so accelerated shall remain exercisable for 
fully-vested shares until the expiration or sooner termination of the option
term.

          H.  The portion of any Incentive Option accelerated in connection with
a Change in Control or Hostile Take Over shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
($100,000) limitation is not exceeded. To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a Non-
Statutory Option under the Federal tax laws.

    IV. STOCK APPRECIATION RIGHTS

          The Plan Administrator may, subject to such conditions as it may
determine, grant to selected Optionees stock appreciation rights which will
allow the holders of those rights to elect between the exercise of the
underlying option for shares of Common Stock and the surrender of that option in
exchange for a distribution from the Corporation in an amount equal to the
excess of (a) the Option Surrender Value of the number of shares for which the
option is surrendered over (b) the aggregate exercise price payable for such
shares. The distribution may be made in shares of Common Stock valued at Fair
Market Value on the option surrender date, in cash, or partly in shares and
partly in cash, as the Plan Administrator shall in its sole discretion deem
appropriate.

                             STOCK ISSUANCE PROGRAM
                             ----------------------

    I.  STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening options.  Shares
of Common Stock may also be issued under the Stock Issuance Program pursuant to
share right awards which entitle the recipients to receive those shares upon the
attainment of designated performance goals or Service requirements.  Each such
award shall be evidenced by one or more documents which comply with the terms
specified below.

          A.  PURCHASE PRICE.
              -------------- 

              1.  The purchase price per share of Common Stock subject to direct
issuance shall be fixed by the Plan Administrator.

              2.  Subject to the provisions of Section II of Article Five,
Shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                    (i)  cash or check made payable to the Corporation, or

                                       9
<PAGE>
 
                 (ii)   past services rendered to the Corporation (or any Parent
     or Subsidiary).

          B.   VESTING/ISSUANCE PROVISIONS.
               --------------------------- 

               1.  The Plan Administrator may issue shares of Common Stock which
are fully and immediately vested upon issuance or which are to vest in one or
more installments over the Participant's period of Service or upon attainment of
specified performance objectives. Alternatively, the Plan Administrator may
issue share right awards which shall entitle the recipient to receive a
specified number of vested shares of Common Stock upon the attainment of one or
more performance goals or Service requirements established by the Plan
Administrator.

               2.  Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to his or her unvested
shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

               3.  The Participant shall have full stockholder rights with
respect to the issued shares of Common Stock, whether or not the Participant's
interest in those shares is vested. Accordingly, the Participant shall have the
right to vote such shares and to receive any regular cash dividends paid on such
shares.

               4.  Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock, or should the performance
objectives not be attained with respect to one or more such unvested shares of
Common Stock, then those shares shall be immediately surrendered to the
Corporation for cancellation, and the Participant shall have no further
stockholder rights with respect to those shares. To the extent the surrendered
shares were previously issued to the Participant for consideration paid in cash
or cash equivalent (including the Participant's purchase-money indebtedness),
the Corporation shall repay to the Participant the cash consideration paid for
the surrendered shares and shall cancel the unpaid principal balance of any
outstanding purchase-money note of the Participant attributable to the
surrendered shares.

               5.  The Plan Administrator may waive the surrender and
cancellation of one or more unvested shares of Common Stock (or other assets
attributable thereto) which would otherwise occur upon the cessation of the
Participant's Service or the non-attainment of the performance objectives
applicable to those shares. Such waiver shall result in the immediate vesting of
the Participant's interest in the shares of Common Stock as to which the waiver
applies. Such waiver may be effected at any time, whether before or after the
Participant's cessation of Service or the attainment or non-attainment of the
applicable performance objectives.

                                       10
<PAGE>
 
               6.  Outstanding share right awards shall automatically terminate,
and no shares of Common Stock shall actually be issued in satisfaction of those
awards, if the performance goals or Service requirements established for such
awards are not attained. The Plan Administrator, however, shall have the
authority to issue shares of Common Stock in satisfaction of one or more
outstanding share right awards as to which the designated performance goals or
Service requirements are not attained.

  II.   CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   All of the Corporation's outstanding repurchase rights shall
terminate automatically, and all the shares of Common Stock subject to those
terminated rights shall immediately vest in full, in the event of any Change in
Control, except to the extent (i) those repurchase rights are assigned to the
successor corporation (or parent thereof) or otherwise continue in full force
and effect pursuant to the terms of the Change in Control or (ii) such
accelerated vesting is precluded by other limitations imposed by the Plan
Administrator at the time the repurchase right is issued.

          B.   The Plan Administrator may at any time provide for the automatic
termination of one or more of those outstanding repurchase rights and the
immediate vesting of the shares of Common Stock subject to those terminated
rights upon (i) a Change in Control or Hostile Take-Over or (ii) an Involuntary
Termination of the Participant's Service within a designated period (not to
exceed eighteen (18) months) following the effective date of any Change in
Control or Hostile Take-Over in which those repurchase rights are assigned to
the successor corporation (or parent thereof) or otherwise continue in full
force and effect.

  III.  SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                                 ARTICLE FOUR
                         AUTOMATIC OPTION GRANT PROGRAM
                         ------------------------------

  I.    OPTION TERMS

          A.   GRANT DATES.  Options shall be made on the dates specified below:
               -----------                                                      

               1.  Each individual who is serving as a non-employee Board member
on the Underwriting Date shall automatically be granted at that time a Non-
Statutory Option to purchase Twenty Thousand (20,000) shares of Common Stock,
provided that individual has not previously been in the employ of the
Corporation or any Parent or Subsidiary.

               2.  Each individual who is first elected or appointed as a non-
employee Board member at any time after the Underwriting Date shall
automatically be granted, on the date of such initial election or appointment, a
Non-Statutory Option to purchase Twenty Thousand (20,000) shares of Common
Stock, provided that individual has not previously been in the employ of the
Corporation or any Parent or Subsidiary.

                                       11
<PAGE>
 
               3.   On the date of each Annual Stockholders Meeting, beginning
with the first Annual Meeting held after the Underwriting Date, each individual
who is to continue to serve as a non-employee Board member, whether or not that
individual is standing for re-election to the Board, shall automatically be
granted a Non-Statutory Option to purchase Five Thousand (5,000) shares of
Common Stock, provided such individual has served as a non-employee Board member
for at least six (6) months.

          B.   EXERCISE PRICE.
               -------------- 

               1.   The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the option
grant date.

               2.   The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

          C.   OPTION TERM.  Each option shall have a term of ten (10) years 
               -----------
measured from the option grant date.

          D.   EXERCISE AND VESTING OF OPTIONS.  Each option shall be 
               -------------------------------  
immediately exercisable for any or all of the option shares. However, any shares
purchased under the option shall be subject to repurchase by the Corporation, at
the exercise price paid per share, upon the Optionee's cessation of Board
service prior to vesting in those shares. Each Twenty Thousand (20,000)-share
option shall vest, and the Corporation's repurchase right shall lapse, in a
series of four (4) successive equal annual installments upon the Optionee's
completion of each year of Board service over the four (4)-year period measured

and the Corporation's repurchase right shall lapse, upon the Optionee's
completion of one (1) year of Board service measured from the grant date.

          E.   LIMITED TRANSFERABILITY OF OPTIONS.  Each option under this 
               ----------------------------------         
Article Four may, in connection with the Optionee's estate plan, be assigned in
whole or in part during the Optionee's lifetime to one or more members of the
Optionee's immediate family or to a trust in which the Optionee and/or one or
more such family members have more than a fifty percent (50%) of the beneficial
interest or to any other entity in which the Optionee and/or one or more such
family members own more than fifty percent (50%) of the voting interests. The
terms applicable to the assigned portion shall be the same as those in effect
for the option immediately prior to such assignment and shall be set forth in
such documents issued to the assignee as the Plan Administrator may deem
appropriate. The Optionee may also designate a Beneficiary or Beneficiaries of
his or her outstanding options under this Article Four, and those options shall,
in accordance with such designation, be automatically transferred to such
Beneficiary or Beneficiaries upon Optionee's death while holding those options.
Such Beneficiary or Beneficiaries shall take the transferred options subject to
the all the terms and conditions of the applicable agreement evidencing each
such transferred option, including (without limitation) the limited time period
during which the option may be exercised following the Optionee's death.

               F.   CESSATION OF BOARD SERVICE.  The following provisions 
                    -------------------------- 
shall govern the exercise of any options outstanding at the time of the
Optionee's cessation of Board service:

                         (i)     Any option outstanding at the time of the
     Optionee's cessation of Board service for any reason shall remain
     exercisable for a twelve (12)-month period following the date of such
     cessation of Board service, but in no event shall such option be
     exercisable after the expiration of the option term.

                         (ii)    Any option held by the Optionee at the time of
     death may be subsequently exercised by his or her Beneficiary to the extent
     that option is exercisable for one or more vested shares at the time of
     Optionee's death.

                         (iii)   Following the Optionee's cessation of Board
     service, the option may not be exercised in the aggregate for more than the
     number of shares in which the Optionee was vested on the date of such
     cessation of Board service. Upon the expiration of the applicable exercise
     period or (if earlier) upon the expiration of the option term, the option
     shall terminate and cease to be outstanding for any vested shares for which
     the option has not been exercised. However, the option shall, immediately
     upon the Optionee's cessation of Board service, terminate and cease to be
     outstanding for any and all shares in which the Optionee is not otherwise
     at that time vested.

                         (iv)    However, should the Optionee cease to serve as
     a Board member by reason of death or Permanent Disability, then all shares
     at the time subject to the option shall immediately vest so that such
     option may, during the twelve (12)-month exercise period following such
     cessation of Board service, be exercised for all or any portion of those
     shares as fully-vested shares of Common Stock.

   II.  CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.  In the event of any Change in Control or Hostile Take-Over, the
shares of Common Stock at the time subject to each outstanding option but not
otherwise vested shall automatically vest in full so that each such option may,
immediately prior to the effective date of such Change in Control the Hostile
Take-Over, be exercised for all or any portion of those shares as fully-vested
shares of Common Stock. Each such option accelerated in connection with a Change
in Control shall terminate upon the Change in Control, except to the extent
assumed by the successor corporation (or parent thereof) or otherwise continued
in full force and effect pursuant to the terms of the Change in Control. Each
such option accelerated in connection with a Hostile Take-Over shall remain
exercisable until the expiration or sooner termination of the option term.

          B.  All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Change in Control or Hostile
Take-Over.

          C.  Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding 

                                       13
<PAGE>
 
options. The Optionee shall in return be entitled to a cash distribution from
the Corporation in an amount equal to the excess of (i) the Option Surrender
Value of the shares of Common Stock at the time subject to each surrendered
option (whether or not the Optionee is otherwise at the time vested in those
shares) over (ii) the aggregate exercise price payable for such shares. Such
cash distribution shall be paid within five (5) days following the surrender of
the option to the Corporation.

               D.  Each option which is assumed in connection with a Change in
Control shall be appropriately adjusted to apply to the number and class of
securities which would have been issuable to the Optionee in consummation of
such Change in Control had the option been exercised immediately prior to such
Change in Control. Appropriate adjustments shall also be made to the exercise
price payable per share under each outstanding option, provided the aggregate
                                                       --------
exercise price payable for such securities shall remain the same.

   III.  REMAINING TERMS

               The remaining terms of each option granted under the Automatic
Option Grant Program shall be the same as the terms in effect for options made
under the Discretionary Option Grant Program.

                                 MISCELLANEOUS
                                 -------------

   I.    NO IMPAIRMENT OF AUTHORITY

               Outstanding awards shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

   II.   FINANCING

               The Plan Administrator may permit any Optionee or Participant to
pay the option exercise price under the Discretionary Option Grant Program or
the purchase price of shares issued under the Stock Issuance Program by
delivering a full-recourse, interest bearing promissory note payable in one or
more installments. The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion. In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

   III.  TAX WITHHOLDING

               A.  The Corporation's obligation to deliver shares of Common
Stock upon the exercise of options or the issuance or vesting of such shares
under the Plan shall be subject to the satisfaction of all applicable Federal,
state and local income and employment tax withholding requirements.

                                       14
<PAGE>
 
          B.   The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan with the right to use shares of Common Stock in satisfaction of all or part
of the Withholding Taxes to which such holders may become subject in connection
with the exercise of their options or the vesting of their shares. Such right
may be provided to any such holder in either or both of the following formats:

               Stock Withholding:  The election to have the Corporation 
               -----------------         
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such Non-Statutory Option or the vesting of such shares, a portion of those
shares with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

               Stock Delivery:  The election to deliver to the Corporation, at
               --------------                                                
the time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Withholding
Taxes) with an aggregate Fair Market Value equal to the percentage of the
Withholding Taxes (not to exceed one hundred percent (100%)) designated by the
holder.

   IV.  EFFECTIVE DATE AND TERM OF THE PLAN
     
          A.   The Plan shall become effective immediately upon the Plan
Effective Date. Options may be granted under the Discretionary Option Grant or
Automatic Option Grant Program at any time on or after the Plan Effective Date.
However, no options granted under the Plan may be exercised, and no shares shall
be issued under the Plan, until the Plan is approved by the Corporation's
stockholders. If such stockholder approval is not obtained within twelve (12)
months after the Plan Effective Date, then all options previously granted under
this Plan shall terminate and cease to be outstanding, and no further options
shall be granted and no shares shall be issued under the Plan.

          B.   The Plan shall serve as the successor to the Predecessor Plan,
and no further options or direct stock issuances shall be made under the
Predecessor Plan after the Section 12 Registration Date. All options outstanding
under the Predecessor Plan on the Section 12 Registration Date shall be
incorporated into the Plan at that time and shall be treated as outstanding
options under the Plan. However, each outstanding option so incorporated shall
continue to be governed solely by the terms of the documents evidencing such
option, and no provision of the Plan shall be deemed to affect or otherwise
modify the rights or obligations of the holders of such incorporated options
with respect to their acquisition of shares of Common Stock.

          C.   One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Changes in Control, may, in the Plan Administrator's discretion, be extended
to one or more options incorporated from the Predecessor Plan which do not
otherwise contain such provisions.

          D.   The Plan shall terminate upon the earliest of (i) April 20, 
                                                 -------- 
2009 (ii) the date on which all shares available for issuance under the Plan
shall have been issued as fully-vested shares or (iii) the termination of all
outstanding options in connection with a Change in Control. Upon such plan
termination, all outstanding options and unvested stock issuances shall
thereafter continue to have force and effect in accordance with the provisions
of the documents evidencing such grants or issuances.

   V.   AMENDMENT OF THE PLAN

                                       15
<PAGE>
 
          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects. However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to stock options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws or regulations.

          B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant Program and shares of Common Stock may be issued
under the Stock Issuance Program that are in each instance in excess of the
number of shares then available for issuance under the Plan, provided any excess
shares actually issued under those programs shall be held in escrow until there
is obtained stockholder approval of an amendment sufficiently increasing the
number of shares of Common Stock available for issuance under the Plan. If such
stockholder approval is not obtained within twelve (12) months after the date
the first such excess issuances are made, then (i) any unexercised options
granted on the basis of such excess shares shall terminate and cease to be
outstanding and (ii) the Corporation shall promptly refund to the Optionees and
the Participants the exercise or purchase price paid for any excess shares
issued under the Plan and held in escrow, together with interest (at the
applicable Short Term Federal Rate) for the period the shares were held in
escrow, and such shares shall thereupon be automatically cancelled and cease to
be outstanding.

  VI.   USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

  VII.  REGULATORY APPROVALS

          A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

          B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

  VIII. NO EMPLOYMENT/SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

                       1999 EMPLOYEE STOCK PURCHASE PLAN
                       ---------------------------------


     I.   PURPOSE OF THE PLAN

          This 1999 Employee Stock Purchase Plan is intended to promote the
interests of Divicore Inc., a Delaware corporation, by providing eligible
employees with the opportunity to acquire a proprietary interest in the
Corporation through participation in a payroll-deduction based employee stock
purchase plan designed to qualify under Section 423 of the Code.


          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.  ADMINISTRATION OF THE PLAN

          The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Section 423 of the Code.  Decisions of the Plan Administrator
shall be final and binding on all parties having an interest in the Plan.

     III.  STOCK SUBJECT TO PLAN

           A.  The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market. The maximum number of shares of Common Stock
which may be issued over the term of the Plan shall not exceed Five Hundred
Thousand (500,000) shares.

          B.   Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and class of securities issuable under
the Plan, (ii) the maximum number and class of securities purchasable per
Participant on any one Purchase Date, (iii) the maximum number and class of
securities purchasable by all Participants in the aggregate on any one Purchase
Date and (iv) the number and class of securities and the price per share in
effect under each outstanding purchase right in order to prevent the dilution or
enlargement of benefits thereunder.

     IV.  OFFERING PERIODS

          A.   Shares of Common Stock shall be offered for purchase under the
Plan through a series of successive offering periods until such time as (i) the
maximum number of shares of Common Stock available for issuance under the Plan
shall have been purchased or (ii) the Plan shall have been sooner terminated.

          B.   Each offering period shall be of such duration (not to exceed
twenty-four (24) months) as determined by the Plan Administrator prior to the
start date of such offering
<PAGE>
 
period. However, the initial offering period shall commence at the Effective
Time and terminate on the last business day in July 2001. Subsequent offering
periods shall commence as designated by the Plan Administrator.

          C.  Each offering period shall be comprised of a series of one or more
successive Purchase Intervals.  Purchase Intervals shall run from the first
business day in February to the last business day in July each  year and from
the first business day in August] each year to the last business day in January
in the following year.  However, the first Purchase Interval in effect under the
initial offering period shall commence at the Effective Time and terminate on
the last business day in January 2000.

          D.  Should the Fair Market Value per share of Common Stock on any
Purchase Date within an offering period be less than the Fair Market Value per
share of Common Stock on the start date of that offering period, then that
offering period shall automatically terminate immediately after the purchase of
shares of Common Stock on such Purchase Date, and a new offering period shall
commence on the next business day following such Purchase Date. The new offering
period shall have a duration of twenty (24) months, unless a shorter duration is
established by the Plan Administrator within five (5) business days following
the start date of that offering period.

          E.  Notwithstanding anything to the contrary herein, should the total
number of shares of Common Stock to be purchased on any particular date exceed
the number of shares then available for issuance under the Plan, then the Plan
Administrator shall have the right to terminate the offering period during which
such purchase occurs and to determine when a new offering period shall commence.

     V.   ELIGIBILITY

          A.  Each individual who is an Eligible Employee on the start date of
any offering period under the Plan may enter that offering period on such start
date or on any subsequent Semi-Annual Entry Date within that offering period,
provided he or she remains an Eligible Employee.

          B.  Each individual who first becomes an Eligible Employee after the
start date of an offering period may enter that offering period on any
subsequent Semi-Annual Entry Date within that offering period on which he or she
is an Eligible Employee.

          C.  The date an individual enters an offering period shall be
designated his or her Entry Date for purposes of that offering period.

          D.  To participate in the Plan for a particular offering period, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (including a stock purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before his or her scheduled Entry Date.

     VI.  PAYROLL DEDUCTIONS

                                       2
<PAGE>
 
          A.  The payroll deduction authorized by the Participant for purposes
of acquiring shares of Common Stock during an offering period may be any
multiple of one percent (1%) of the Cash Earnings paid to the Participant during
each Purchase Interval within that offering period, up to a maximum of fifteen
percent (15%). The deduction rate so authorized shall continue in effect
throughout the offering period, except to the extent such rate is changed in
accordance with the following guidelines:

                    (i)  The Participant may, at any time during the offering
     period, reduce his or her rate of payroll deduction to become effective as
     soon as possible after filing the appropriate form with the Plan
     Administrator. The Participant may not, however, effect more than one (1)
     such reduction per Purchase Interval.

                    (ii) The Participant may, prior to the commencement of any
     new Purchase Interval within the offering period, increase the rate of his
     or her payroll deduction by filing the appropriate form with the Plan
     Administrator. The new rate (which may not exceed the fifteen percent (15%)
     maximum) shall become effective on the start date of the first Purchase
     Interval following the filing of such form.

          B.  Payroll deductions shall begin on the first pay day following the
Participant's Entry Date into the offering period and shall (unless sooner
terminated by the Participant) continue through the pay day ending with or
immediately prior to the last day of that offering period.  The amounts so
collected shall be credited to the Participant's book account under the Plan,
but no interest shall be paid on the balance from time to time outstanding in
such account.  The amounts collected from the Participant shall not be required
to be held in any segregated account or trust fund and may be commingled with
the general assets of the Corporation and used for general corporate purposes.

          C.  Payroll deductions shall automatically cease upon the termination
of the Participant's purchase right in accordance with the provisions of the
Plan.

          D.  The Participant's acquisition of Common Stock under the Plan on
any Purchase Date shall neither limit nor require the Participant's acquisition
of Common Stock on any subsequent Purchase Date, whether within the same or a
different offering period.

     VII. PURCHASE RIGHTS

          A.  GRANT OF PURCHASE RIGHT.  A Participant shall be granted a
              -----------------------
separate purchase right for each offering period in which he or she
participates. The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the Participant with the right
to purchase shares of Common Stock, in a series of successive installments over
the remainder of such offering period, upon the terms set forth below. The
Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

          Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock 

                                       3
<PAGE>
 
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of the Corporation or any Corporate Affiliate.

          B.  EXERCISE OF THE PURCHASE RIGHT.  Each purchase right shall be
              ------------------------------
automatically exercised in installments on each successive Purchase Date within
the offering period, and shares of Common Stock shall accordingly be purchased
on behalf of each Participant (other than Participants whose payroll deductions
have previously been refunded pursuant to the Termination of Purchase Right
provisions below) on each such Purchase Date. The purchase shall be effected by
applying the Participant's payroll deductions for the Purchase Interval ending
on such Purchase Date to the purchase of whole shares of Common Stock at the
purchase price in effect for the Participant for that Purchase Date.

          C.  PURCHASE PRICE.  The purchase price per share at which Common
              --------------
Stock will be purchased on the Participant's behalf on each Purchase Date within
the offering period shall be equal to eighty-five percent (85%) of the lower of
                                                                       -----
(i) the Fair Market Value per share of Common Stock on the Participant's Entry
Date into that offering period or (ii) the Fair Market Value per share of Common
Stock on that Purchase Date.

          D.  NUMBER OF PURCHASABLE SHARES.  The number of shares of Common
              ---------------------------- 
Stock purchasable by a Participant on each Purchase Date during the offering
period shall be the number of whole shares obtained by dividing the amount
collected from the Participant through payroll deductions during the Purchase
Interval ending with that Purchase Date by the purchase price in effect for the
Participant for that Purchase Date. However, the maximum number of shares of
Common Stock purchasable per Participant on any one Purchase Date shall not
exceed One Thousand Three Hundred (1,300) shares, subject to periodic
adjustments in the event of certain changes in the Corporation's capitalization.
In addition, the maximum aggregate number of shares of Common Stock purchasable
by all Participants on any one Purchase Date shall not exceed One Hundred 
Twenty-Five Thousand (125,000) shares, subject to periodic adjustments in the
event of certain changes in the Corporation's capitalization. However, the Plan
Administrator shall have the discretionary authority, exercisable prior to the
start of any offering period under the Plan, to increase or decrease the
limitations to be in effect for the number of shares purchasable per participant
and in the aggregate by all Participants on each Purchase Date within that
offering period.

          E.  EXCESS PAYROLL DEDUCTIONS.  Any payroll deductions not applied to
              -------------------------
the purchase of shares of Common Stock on any Purchase Date because they are not
sufficient to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date. However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable on the Purchase Date
shall be promptly refunded.

          F.  TERMINATION OF PURCHASE RIGHT.  The following provisions shall
              ----------------------------- 
govern the termination of outstanding purchase rights:

                    (i)  A Participant may, at any time prior to the next
     scheduled Purchase Date in the offering period, terminate his or her
     outstanding purchase right by filing the appropriate form with the Plan
     Administrator (or its designate), and no further

                                       4
<PAGE>
 
     payroll deductions shall be collected from the Participant with respect to
     the terminated purchase right. Any payroll deductions collected during the
     Purchase Interval in which such termination occurs shall, at the
     Participant's election, be immediately refunded or held for the purchase of
     shares on the next Purchase Date. If no such election is made at the 
     timesuch purchase right is terminated, then the payroll deductions
     collected with respect to the terminated right shall be refunded as soon as
     possible.

                         (ii)   The termination of such purchase right shall be
     irrevocable, and the Participant may not subsequently rejoin the offering
     period for which the terminated purchase right was granted. In order to
     resume participation in any subsequent offering period, such individual
     must re-enroll in the Plan (by making a timely filing of the prescribed
     enrollment forms) on or before his or her scheduled Entry Date into that
     offering period.

                         (iii)  Should the Participant cease to remain an
     Eligible Employee for any reason (including death, disability or change in
     status) while his or her purchase right remains outstanding, then that
     purchase right shall immediately terminate, and all of the Participant's
     payroll deductions for the Purchase Interval in which the purchase right so
     terminates shall be immediately refunded. However, should the Participant
     cease to remain in active service by reason of an approved unpaid leave of
     absence, then the Participant shall have the right, exercisable up until
     the last business day of the Purchase Interval in which such leave
     commences, to (a) withdraw all the payroll deductions collected to date on
     his or her behalf for that Purchase Interval or (b) have such funds held
     for the purchase of shares on his or her behalf on the next scheduled
     Purchase Date. In no event, however, shall any further payroll deductions
     be collected on the Participant's behalf during such leave. Upon the
     Participant's return to active service (i) within ninety (90) days
     following the commencement of such leave or, (ii) prior to the expiration
     of any longer period for which such Participant's right to reemployment
     with the Corporation is guaranteed by either statute or contract, his or
     her payroll deductions under the Plan shall automatically resume at the
     rate in effect at the time the leave began. However, should the
     Participant's leave of absence exceed ninety (90) days and his or her re-
     employment rights not be guaranteed by either statute or contract, then the
     Participant's status as an Eligible Employee will be deemed to terminate on
     the ninety-first (91st) day of that leave, and such Participant's purchase
     right for the offering period in which that leave began shall thereupon
     terminate. An individual who returns to active employment following such a
     leave shall be treated as a new Employee for purposes of the Plan and must,
     in order to resume participation in the Plan, re-enroll in the Plan (by
     making a timely filing of the prescribed enrollment forms) on or before his
     or her scheduled Entry Date into the offering period.

          G.  CHANGE IN CONTROL.  Each outstanding purchase right shall
              ----------------- 
   automatically be exercised, immediately prior to the effective date of any
   Change in Control, by applying the payroll deductions of each Participant for
   the Purchase Interval in which such Change in Control occurs to the purchase
   of whole shares of Common Stock at a purchase price per share equal to 
   eighty-five percent (85%) of the lower of (i) the Fair Market Value per share
                                    -----    
   of Common Stock on the Participant's Entry Date into the offering period in
   which such Change in Control occurs or (ii) the Fair Market Value per share
   of Common Stock immediately prior to the effective date

                                       5
<PAGE>
 
     of such Change in Control. However, the applicable limitations on the
     number of shares of Common Stock purchasable per Participant shall continue
     to apply to any such purchase, but not the limitation applicable to the
     maximum number of shares of Common Stock purchasable in the aggregate.

               The Corporation shall use its best efforts to provide at least
     ten (10)-days prior written notice of the occurrence of any Corporate
     Transaction, and Participants shall, following the receipt of such notice,
     have the right to terminate their outstanding purchase rights prior to the
     effective date of the Corporate Transaction.

               H.  PRORATION OF PURCHASE RIGHTS.  Should the total number of 
                   ---------------------------- 
     shares of Common Stock to be purchased pursuant to outstanding purchase
     rights on any particular date exceed the number of shares then available
     for issuance under the Plan, the Plan Administrator shall make a pro-rata
     allocation of the available shares on a uniform and nondiscriminatory
     basis, and the payroll deductions of each Participant, to the extent in
     excess of the aggregate purchase price payable for the Common Stock pro-
     rated to such individual, shall be refunded.

               I.  ASSIGNABILITY.  The purchase right shall be exercisable only
                   -------------
     by the Participant and shall not be assignable or transferable by the
     Participant.

               J.  STOCKHOLDER RIGHTS.  A Participant shall have no stockholder
                   ------------------
     rights with respect to the shares subject to his or her outstanding
     purchase right until the shares are purchased on the Participant's behalf
     in accordance with the provisions of the Plan and the Participant has
     become a holder of record of the purchased shares.

        VIII.  ACCRUAL LIMITATIONS

               A.  No Participant shall be entitled to accrue rights to acquire
Common Stock pursuant to any purchase right outstanding under this Plan if and
to the extent such accrual, when aggregated with (i) rights to purchase Common
Stock accrued under any other purchase right granted under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

               B.  For purposes of applying such accrual limitations to the
purchase rights granted under the Plan, the following provisions shall be in
effect:

                         (i)   The right to acquire Common Stock under each
     outstanding purchase right shall accrue in a series of installments on each
     successive Purchase Date during the offering period on which such right
     remains outstanding.

                         (ii)  No right to acquire Common Stock under any
     outstanding purchase right shall accrue to the extent the Participant has
     already accrued in the same calendar year the right to acquire Common Stock
     under one (1) or more other purchase rights at a rate equal to Twenty-Five
     Thousand Dollars ($25,000) worth of Common 

                                       6
<PAGE>
 
     Stock (determined on the basis of the Fair Market Value per share on the
     date or dates of grant) for each calendar year such rights were at any time
     outstanding.

          C.  If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Interval, then the payroll
deductions which the Participant made during that Purchase Interval with respect
to such purchase right shall be promptly refunded.

          D.  In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

     IX.  EFFECTIVE DATE AND TERM OF THE PLAN

          A.  The Plan was adopted by the Board in April 1999 and shall become
effective at the Effective Time, provided no purchase rights granted under the
                                 --------
Plan shall be exercised, and no shares of Common Stock shall be issued
hereunder, until (i) the Plan shall have been approved by the stockholders of
the Corporation and (ii) the Corporation shall have complied with all applicable
requirements of the 1933 Act (including the registration of the shares of Common
Stock issuable under the Plan on a Form S-8 registration statement filed with
the Securities and Exchange Commission), all applicable listing requirements of
any stock exchange (or the Nasdaq National Market, if applicable) on which the
Common Stock is listed for trading and all other applicable requirements
established by law or regulation. In the event such stockholder approval is not
obtained, or such compliance is not effected, within twelve (12) months after
the date on which the Plan is adopted by the Board, the Plan shall terminate and
have no further force or effect, and all sums collected from Participants during
the initial offering period hereunder shall be refunded.

          B.  Unless sooner terminated by the Board, the Plan shall terminate
upon the earliest of (i) the last business day in July 2009, (ii) the date on
         -------- 
which all shares available for issuance under the Plan shall have been sold
pursuant to purchase rights exercised under the Plan or (iii) the date on which
all purchase rights are exercised in connection with a Corporate Transaction. No
further purchase rights shall be granted or exercised, and no further payroll
deductions shall be collected, under the Plan following such termination.

     X.   AMENDMENT/TERMINATION OF THE PLAN

          A.  The Board may alter, amend, suspend or terminate the Plan at any
time to become effective immediately following the close of any Purchase
Interval. However, the Plan may be amended or terminated immediately upon Board
action, if and to the extent necessary to assure that the Corporation will not
recognize, for financial reporting purposes, any compensation expense in
connection with the shares of Common Stock offered for purchase under the Plan,
should the financial accounting rules applicable to the Plan at the Effective
Time be subsequently revised so as to require the recognition of compensation
expense in the absence of such amendment or termination.

          B.  In no event may the Board effect any of the following amendments
or revisions to the Plan without the approval of the Corporation's stockholders:
(i) increase the 

                                       7
<PAGE>
 
number of shares of Common Stock issuable under the Plan, except for permissible
adjustments in the event of certain changes in the Corporation's capitalization,
(ii) alter the purchase price formula so as to reduce the purchase price payable
for the shares of Common Stock purchasable under the Plan or (iii) modify the
eligibility requirements for participation in the Plan.

     XI.  GENERAL PROVISIONS

          A.  Nothing in the Plan shall confer upon the Participant any right to
continue in the employ of the Corporation or any Corporate Affiliate for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment at any time for any reason, with or without
cause.

          B.  All costs and expenses incurred in the administration of the Plan
shall be paid by the Corporation; however, each Plan Participant shall bear all
costs and expenses incurred by such individual in the sale or other disposition
of any shares purchased under the Plan.

                           INDEMNIFICATION AGREEMENT


          THIS INDEMNIFICATION AGREEMENT (this "Agreement") is made and entered
into this ____ day of ______, between Divicore Inc., a Delaware corporation (the
"Company"), and ___________________ ("Indemnitee").

          WHEREAS, Indemnitee, a member of the Board of Directors or an officer,
employee or agent of the Company, performs a valuable service in such capacity
for the Company;

          WHEREAS, the stockholders of the Company have adopted Bylaws (the
"Bylaws") providing for the indemnification of the officers, directors,
employees and agents of the Company to the maximum extent authorized by Section
145 of the Delaware General Corporation Law, as amended (the "Code");

          WHEREAS, the Bylaws and the Code, by their non-exclusive nature,
permit contracts between the Company and the members of its Board of Directors,
officers, employees or agents with respect to indemnification of such directors,
officers, employees or agents;

          WHEREAS, in accordance with the authorization as provided by the Code,
the Company either has purchased and presently maintains or intends to purchase
and maintain a policy or policies of Directors and Officers Liability Insurance
("D & O Insurance") covering certain liabilities which may be incurred by its
directors and officers in the performance of their duties as directors and
officers of the Company;

          WHEREAS, as a result of developments affecting the terms, scope and
availability of D & O Insurance there exists general uncertainty as to the
extent of protection afforded members of the Board of Directors or officers,
employees or agents by such D & O Insurance and by statutory and bylaw
indemnification provisions; and

          WHEREAS, in order to induce Indemnitee to continue to serve as a
member of the Board of Directors, officer, employee or agent of the Company, the
Company has determined and agreed to enter into this contract with Indemnitee.

          NOW, THEREFORE, in consideration of Indemnitee's continued service as
a director, officer, employee or agent after the date hereof, and for other good
and valid consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:

          1.  Indemnification of Indemnitee.   The Company hereby agrees to hold
              -----------------------------                                     
harmless and indemnify Indemnitee to the fullest extent authorized or permitted
by the provisions of the Code, as may be amended from time to time.
<PAGE>
 
          2.  Additional Indemnity.  Subject only to the exclusions set forth in
              --------------------                                              
Sections 3 and 6(c) hereof, the Company hereby further agrees to hold harmless
and indemnify Indemnitee:

              (a)  against any and all expenses (including attorneys' fees),
witness fees, judgments, fines and amounts paid in settlement actually and
reasonably incurred by Indemnitee in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (including an action by or in the right of the Company) to which
Indemnitee is, was or at any time becomes a party, or is threatened to be made a
party, by reason of the fact that Indemnitee is, was or at any time becomes a
director, officer, employee or agent of the Company or any subsidiary of the
Company, or is or was serving or at any time serves at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise;
and

              (b)  otherwise to the fullest extent as may be provided to
Indemnitee by the Company under the non-exclusivity provisions of Article VII,
Section 6 of the Bylaws of the Company and the Code.

          3.  Limitations on Additional Indemnity.
              ----------------------------------- 

              (a)   No indemnity pursuant to Section 2 hereof shall be paid by
the Company:

                   i)    in respect to remuneration paid to Indemnitee if it
shall be determined by a final judgment or other final adjudication that such
remuneration was in violation of law;

                  ii)    on account of any suit in which judgment is rendered
against Indemnitee for an accounting of profits made from the purchase or sale
by Indemnitee of securities of the Company pursuant to the provisions of Section
16(b) of the Securities Exchange Act of 1934 and amendments thereto or similar
provisions of any federal, state or local statutory law;

                 iii)    on account of Indemnitee's conduct which is finally
adjudged to have been knowingly fraudulent or deliberately dishonest or to
constitute willful misconduct;

                  iv)    on account of Indemnitee's conduct which is the subject
of an action, suit or proceeding described in Section 6(c)(ii) hereof;

                   v)    on account of any action, claim or proceeding (other
than a proceeding referred to in Section 7(b) hereof) initiated by the
Indemnitee unless such action, claim or proceeding was authorized in the
specific case by action of the Board of Directors;

                  vi)    if a final decision by a Court having jurisdiction in
the matter shall determine that such indemnification is not lawful (and, in this
respect, both the Company and Indemnitee have been advised that the Securities
and Exchange Commission 

                                       2
<PAGE>
 
believes that indemnification for liabilities arising under the federal
securities laws is against public policy and is, therefore, unenforceable and
that claims for indemnification should be submitted to appropriate courts for
adjudication); and

                    vii)    except to the extent the aggregate of losses to be
indemnified thereunder exceeds the sum of (a) such losses for which the
Indemnitee is indemnified pursuant to Section 1 hereof and (b) any additional
amount paid to the Indemnitee pursuant to any D & O Insurance purchased and
maintained by the Company.

                    (b)  No indemnity pursuant to Section 1 or 2 hereof shall be
paid by the Company if the action, suit or proceeding with respect to which a
claim for indemnity hereunder is made arose from or is based upon any of the
following:

                      i)    Any solicitation of proxies by Indemnitee, or by a
group of which he was or became a member consisting of two or more persons that
had agreed (whether formally or informally and whether or not in writing) to act
together for the purpose of soliciting proxies, in opposition to any
solicitation of proxies approved by the Board of Directors.

                     ii)    Any activities by Indemnitee that constitute a
breach of or default under any agreement between Indemnitee and the Company.

               4.   Contribution.  If the indemnification provided in Sections
                    ------------ 
1 and 2 hereof is unavailable by reason of a Court decision described in Section
3(a)(vi) hereof based on grounds other than any of those set forth in paragraphs
(i) through (v) of Section 3 (a) hereof, then in respect of any threatened,
pending or completed action, suit or proceeding in which the Company is jointly
liable with Indemnitee (or would be if joined in such action, suit or
proceeding), the Company shall contribute to the amount of expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred and paid or payable by Indemnitee in such proportion as is
appropriate to reflect (i) the relative benefits received by the Company on the
one hand and Indemnitee on the other hand from the transaction from which such
action, suit or proceeding arose, and (ii) the relative fault of the Company on
the one hand and of Indemnitee on the other in connection with the events which
resulted in such expenses, judgments, fines or settlement amounts, as well as
any other relevant equitable considerations. The relative fault of the Company
on the one hand and of Indemnitee on the other shall be determined by reference
to, among other things, the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent the circumstances resulting in
such expenses, judgments, fines or settlement amounts. The Company agrees that
it would not be just and equitable if contribution pursuant to this Section 4
were determined by pro rata allocation or any other method of allocation which
does not take account of the foregoing equitable considerations.

               5.   Notification and Defense of Claim.  Not later than thirty
                    ---------------------------------
(30) days after receipt by Indemnitee of notice of the commencement of any
action, suit or proceeding, Indemnitee shall, if a claim in respect thereof is
to be made against the Company under this Agreement, notify the Company of the
commencement thereof; but Indemnitee's omission so to notify the Company will
not relieve the Company from any liability which it may have to 

                                       3
<PAGE>
 
Indemnitee otherwise than under this Agreement. With respect to any such action,
suit or proceeding as to which Indemnitee notifies the Company of the
commencement thereof:

               (a) The Company will be entitled to participate therein at its
own expense.

               (b) Except as otherwise provided below, to the extent that it may
wish, the Company shall, jointly with any other indemnifying party similarly
notified, be entitled to assume the defense thereof, with counsel reasonably
satisfactory to Indemnitee.  After notice from the Company to Indemnitee of its
election to assume the defense thereof, the Company will not be liable to
Indemnitee under this Agreement for any legal or other expenses subsequently
incurred by Indemnitee in connection with the defense thereof, other than
reasonable costs of investigation or as otherwise provided below.  Indemnitee
shall have the right to employ its own counsel in such action, suit or
proceeding, but the fees and expenses of such counsel incurred after notice from
the Company of the Company's assumption of the defense thereof shall be at the
expense of Indemnitee unless (i) the employment of counsel by Indemnitee has
been authorized by the Company; (ii) Indemnitee shall have reasonably concluded
that there may be a conflict of interest between the Company and Indemnitee in
the conduct of the defense of such action; or (iii) the Company shall not in
fact have employed counsel to assume the defense of such action; in each of
which cases the fees and expenses of Indemnitee's separate counsel shall be paid
by the Company.  The Company shall not be entitled to assume the defense of any
action, suit or proceeding brought by or on behalf of the Company or as to which
Indemnitee shall have made the conclusion provided for in (ii) above.

               (c) The Company shall not be liable to indemnify Indemnitee under
this Agreement for any amounts paid in settlement of any action or claim
effected without its written consent. The Company shall be permitted to settle
any action except that it shall not settle any action or claim in any manner
which would impose any penalty or limitation on Indemnitee without Indemnitee's
written consent. Neither the Company nor Indemnitee will unreasonably withhold
its consent to any proposed settlement.

          6.   Advancement and Repayment of Expenses.
               ------------------------------------- 

               (a) In the event that Indemnitee employs his or her own counsel
pursuant to Sections 5(b)(i) through (iii) above, the Company shall advance to
Indemnitee, prior to any final disposition of any threatened or pending action,
suit or proceeding, whether civil, criminal, administrative or investigative,
any and all reasonable expenses (including legal fees and expenses) incurred in
investigating or defending any such action, suit or proceeding within ten (10)
days after receiving from Indemnitee copies of invoices presented to Indemnitee
for such expenses.

               (b) Indemnitee agrees that Indemnitee will reimburse the Company
for all reasonable expenses paid by the Company in investigating or defending
any civil or criminal action, suit or proceeding against Indemnitee in the event
and only to the extent it shall be ultimately determined by a final judicial
decision (from which there is no right of appeal) that Indemnitee is not
entitled, under the provisions of the Code, the Bylaws, this Agreement or
otherwise, to be indemnified by the Company for such expenses.

                                       4
<PAGE>
 
               (c) Notwithstanding the foregoing, the Company shall not be
required to advance such expenses to Indemnitee in respect of any action arising
from or based upon any of the matters set forth in subsection (b) of Section 3
or if Indemnitee (i) commences any action, suit or proceeding as a plaintiff
unless such advance is specifically approved by a majority of the Board of
Directors or (ii) is a party to an action, suit or proceeding brought by the
Company and approved by a majority of the Board which alleges willful
misappropriation of corporate assets by Indemnitee, disclosure of confidential
information in violation of Indemnitee's fiduciary or contractual obligations to
the Company, or any other willful and deliberate breach in bad faith of

Frank Wilde
President
Quadrant International
269 Great Valley Parkway
Malvern, PA 19355

Dear Frank:

We welcome Quadrant International as a Dell supplier and look forward to a
mutually beneficial working relationship.  The Products you will supply to Dell
and related information are stated on the attachment to this letter.  This
letter and the Product Labeling, Packaging and Quality Specifications supplement
the terms and conditions of the standard Dell Purchase Order ("Dell PO").  In
the event of a conflict with this or any attachment, the terms of this letter
control. The Dell PO and this letter set forth the only terms by which we will
do business.  In the event we need to modify these terms in the future, we can
do so in a letter signed by each of us.

Unless one of its informs the other of its intent to terminate this agreement
sooner, the term of our agreement shall be one year, beginning on the date of
this letter.  This agreement will automatically renew for one-year terms unless
one party informs the other of its intent to terminate the agreement thirty days
(unless otherwise indicated "days" shall mean calendar days) before the end of
the current term.  Either party may terminate this agreement based on the
material breach of the other party, provided that the party alleged to be in
material breach receives thirty days written notice stating the cause and an
additional thirty days to cure.  Either party may terminate this agreement
without cause with ninety days prior written notice to the other party.

Meeting scheduled delivery dates is a material term of this agreement.  Quadrant
International agrees to fill all Dell POs and will use reasonable efforts to
reduce the lead time during the term of this agreement.  Quadrant International
agrees to maintain a buffer stock of Product Inventory in an amount equal to
Dell's forecasted two week use requirements ("Revolver Inventory") in close
proximity to Dell's manufacturing locations: AMF - Austin, Texas; EMF -
Limerick, Ireland; APCC - Penang, Malaysia.

Quadrant International agrees to meet all scheduled delivery dates including all
acceleration targets set forth in this agreement, its attachment and related
purchase order(s).  Any failure by Quadrant International to meet these dates or
targets will greatly impact Dell's ability to manufacture, support, distribute,
license and sell its systems.  Therefore, Quadrant International agrees to place
the following, materials into escrow:  (1) detailed Costed BOM with Approved
Supplier List, (2) all Software, in both source code and object code forms, (3)
all Documentation and (4) any other materials necessary to enable Dell to
manufacture, support, distribute, license and sell the Products, Software and
Documentation ("Escrow Materials").  Quadrant International also agrees to
provide on-site expert engineering at Dell to assistance in manufacturing,
design and validation.  Quadrant International shall update the Escrow Materials
within five days after any modification is made by Quadrant International to the
Escrow Materials.  The escrow agent will be mutually agreed upon and Dell shall
be responsible for paying the escrow agent's fees.

The Escrow Materials shall be released to Dell by the escrow agent under the
following circumstances:  (1) Quadrant International is in breach of this
agreement and Dell has notified Quadrant International in writing and provided a
five day period to cure the breach, (2) Dell requests assurances that Quadrant
International will be able to meet its delivery dates and acceleration targets
and such assurances are not acceptable to Dell or (3) any adjudication of
bankruptcy or judgment of insolvency is filed by or against Quadrant
International or there is an assignment for the benefit of any creditor.

Dell agrees not to exercise the following rights until the Escrow Materials are
released to Dell by the escrow agent.  Quadrant International hereby grants to
Dell an irrevocable, worldwide, royalty free, fully paid up, non-exclusive right
and license under any copyrights, patents, patent applications, trade secrets
and other necessary intellectual property rights to: (1) use, make, reproduce,
display, perform and prepare derivative works of the Escrow Materials
<PAGE>
 
for the purposes of enabling Dell to manufacture, support distribute, license
and sell the Products, Software and Documentation in connection with Dell
systems and (2) authorize and license, with Quadrant International's written
permission, Dell's agents to do any of the foregoing on Dell's behalf. The terms
and conditions of this agreement, its attachment and related purchase order(s)
including, without limitation, all warranty and indemnification provisions,
shall apply to all Products, Software and Documentation manufactured by Dell or
its agents as if they were manufactured by Quadrant International.

Quadrant International warrants the Products for a period of five (5) years from
date of delivery.  Further, Product quality must be maintained and consistently
improved by Quadrant International.  Accordingly, Quadrant International will
manufacture and assemble the Products only in the location(s) set forth on the
attachment, and must provide Dell ninety days written notice of a change in
manufacturing and/or assembly location.

Quadrant International grants to Dell, under all necessary intellectual property
rights, including, without limitation, copyrights, patents and trademarks, the
rights and license to distribute and market the Product(s), which include, or
are based upon, DVD technology.  Quadrant International represents and warrants
to Dell that it has the right to grant the above right and license and that any
royalties paid for DVD technology licenses are passed through to Dell in the
Product price without any added amount.

To establish acceptable product quality, Quadrant International agrees to
include Dell Product and test requirements in its initial test project reviews.
In order to improve Product quality, Quadrant International agrees to conduct
weekly meetings, generally by phone, to address quality issues.  Quadrant
International will submit to annual design, facility, process, and quality
audits during the term of this agreement, and at any additional time Dell
determines that product quality is unacceptable.  Dell will provide three
business days notice when reasonable of its intent to conduct an audit.  Upon
Dell's request, Quadrant International will provide to Dell or its authorized
representatives:  (i) information requested by Dell related to product quality,
and (ii) reasonable access to its facilities and employees during normal
business hours for the purpose of conducting an audit.  Audits will be conducted
under a non-disclosure agreement between the parties.

After audit results have been prepared, Quadrant International agrees to
establish a failure review and corrective action team to manage corrective and
preventative actions arising from the audit report.  Quadrant International will
assign a failure analysis engineer to work with Dell to address quality issues
and to oversee Product testing in accordance with a customized Dell test plan.

Quadrant International will issue RMA numbers within twenty four hours of Dell's
request and agrees to segregate and separately report line and field returns by
region.  Quadrant International also agrees to provide failure analysis to
component level within ten days of receipt of returned Products and will, at
Dell's option, provide a credit for the purchase price, or return replacement
Product(s). to Dell no later than fifteen days after receipt of returned
Products.  Replacement Products shall be fully warranted upon re-receipt at
incoming inspection.  Additionally, Quadrant International warrants that the
Products shall be able to accurately process date data (including, but not
limited to, calculating, comparing, and sequencing) between the twentieth and
twenty-first centuries and that the Products are certified by Microsoft as PC 9x
compliant or Quadrant International can demonstrate in writing that Microsoft
has exempted the Products from PC 9x compliance.

Quadrant International agrees to provide Dell with a concise printed end user
Product guide containing instructions for operation of the Product and a Product
registration card without any advertising content ("Documentation").  Dell may
distribute Documentation and/or post Documentation, in electronic form, on
bulletin boards.  Quadrant International agrees to provide national language
versions of Documentation to Dell including, but not limited to English, French,
German and Japanese.  Dell may add the following languages to the list of
required national language versions with written notice to Quadrant
International: Spanish, Simplified and Traditional Chinese.

For all device drivers, firmware, and all necessary software for the proper
operation and support of the Product (collectively "Software"), Dell is granted
a non-exclusive, irrevocable, royalty free, worldwide, right and license, to
use, reproduce and distribute Software in connection with Dell's distribution
and support of the Product.  Quadrant International agrees to provide all
updates and modifications to the Software to Dell during the term of our
agreement.  The obligations related to the Product contained in the Dell PO
apply equally to Software.

                                       2
<PAGE>
 
Quadrant International warrants that any returned Product is new and unused and
has not been refurbished.  If Dell requests refurbished Product, such Product
will he provided to Dell clearly marked as such.  QUADRANT INTERNATIONAL shall
indemnify and hold harmless Dell from any claims, liabilities or damages,
including reasonable attorneys fees, arising out of or relating to Quadrant
International Graphic's provision of refurbished Product that is not clearly and
conspicuously labeled as such.

The cost and rates for repairs shall be set forth in the attachment.  End of
life and retention of spares are addressed in the attachment as well.

Since Dell transacts business with the United States government, Quadrant
International must comply with applicable laws and Federal Acquisition
Regulations ("FARs") including the following:

     It is Dell's policy to take affirmative action to provide equal employment
     opportunity without regard to race, religion, color, national origin, age,
     sex, disability, veterans status or any other legally protected status.  As

     the Vietnam Era Veteran's Readjustment Assistance Act of 1974, all as
     amended, and the relevant Regulations and Orders of the U.S. Secretary of
     Labor.  Additionally, to the extent required by applicable law, the
     following sections of Chapter 60 of Title 41 of the Code of Federal
     Regulations are incorporated by reference in this Agreement and each Order:

     economically disadvantaged individuals, and small business concerns owned
     and controlled by women shall have the maximum practicable opportunity to
     participate in performing contracts for any Federal agency.  Quadrant
     International agrees to comply with this policy and to provide reporting of
     data as requested to the Small Business Liaison Officer, Dell Computer
     Corporation, One Dell Way, Round Rock, Texas, 78682.

Before either party initiates a lawsuit against the other relating to this
agreement, the parties agree to work in good faith to resolve between them all
disputes and claims arising out of or relating to this agreement, the parties'
performance under it, or its breach.  To this end, either party may request,
after informal discussions have failed to resolve a dispute or claim, that each
party designate an officer or other management employee with authority to bind
the party to meet in good faith and attempt to resolve the dispute or claim.
During their discussions, each party will honor the other's reasonable requests
for information relating to the dispute or claim.

Please sign and date both original copies of this letter, retain a fully signed
original for your records and return a fully signed original to Dell in the
envelope we have provided.

                   -----------------------------
Items to other Persons, but only to the extent required under applicable law or
by a government order, decree, regulation or rule, provided that ST gives QI
reasonable written notice with sufficient opportunity to seek a protective order
prior to such disclosure.

             7.3   Ownership of Proprietary Items. The Proprietary Items are and
                   ------------------------------ 
will be and remain the exclusive property of QI. At QI's request, ST will
promptly destroy, erase or deliver to QI all copies of any documents containing
any Proprietary Items which are in ST's

                                       10
<PAGE>
 
possession or control or the possession or control of any Person to whom
disclosed by or on behalf of ST under this Agreement except to the extent that
ST is not in breach of this Agreement and ST requires such Proprietary Items to
obtain the full benefits of its rights granted in this Agreement.

SECTION 8:   SPECIFIC OBLIGATIONS OF ST
             --------------------------

          8.1   Exportation of Technical Data or Products.  ST shall not,
                -----------------------------------------
without the prior written consent of QI and the Office of Export Administrator,
United States Department of Commerce, knowingly re-export, export, or ship, or
cause to be re-exported, exported, or shipped, directly or indirectly, any
software licensed hereunder, or any related technology, or any direct or
indirect product thereof, to any country to which, under the laws of the United
States, QI is or may be prohibited from exporting its technology or its direct
or indirect product. The provisions of this paragraph shall extend automatically
to any other destination to which the U.S. Office of Export Administration at
any time during the life of this Agreement restricts or prohibits the export of
technical data or any direct or indirect product thereof.

          8.2   Not Contest Validity.  ST will not, directly or indirectly,
                --------------------                                       
during the Term of this Agreement or at any time thereafter, contest or aid
others in contesting, or do or fail to do anything impairing the validity or
enforceability of any of the rights granted by QI to ST hereunder or the
Proprietary Items anywhere in the world, or the validity of QI's ownership
rights therein.  Notwithstanding the foregoing, nothing in this Agreement shall
be construed as prohibiting ST from contesting the validity of any patents
issuing from the foregoing.

SECTION 9:   INDEMNIFICATION
             ---------------

          9.1   Mutual.  Each party agrees to defend, indemnify and hold
                ------
harmless the other party and its officers, directors, employees, agents and
contractors ("Indemnitees") from and against any and all claims, actions,
liabilities, obligations, damages, losses, demands, recoveries, deficiencies,
costs or expenses, including without limitation, reasonable attorneys fees and
expenses, which an Indemnitee may suffer or incur connected with, resulting from
or arising out of such party's breach of its representations, warranties and/or
covenants made in this Agreement.

          9.2   Licensed Intellectual Property.
                ------------------------------ 

          (a)   QI agrees to defend, indemnify and hold harmless ST from and
against any and all claims, actions, liabilities, obligations, damages, losses,
demands, recoveries, deficiencies, costs or expenses, including without
limitation, reasonable attorneys fees and expenses, which ST may suffer or incur
connected with, resulting from or arising out of the infringement or
misappropriation of a third party Intellectual Property Right by the materials
supplied by QI, including QI Software DVD and/or Shippable DVD Software.  The
foregoing indemnity will not apply to any infringement or misappropriation claim
arising from (i) any modifications to the Shippable DVD Software wherein the
claim arises as a result of such modification and the modification was made by
parties other than QI or a Person under QI's control, or (ii) any combination of
any Shippable DVD Software with other products or 

                                       11
<PAGE>
 
components where there would be no infringement absent such use with such other
products or components (excluding ST Products and/or software embedded therein).

          (b)   Notwithstanding the foregoing, QI shall have no obligation to
defend, indemnify or hold ST or any Affiliate harmless under this Agreement with
respect to any claims, actions, liabilities, obligations, damages, losses,
demands, recoveries, deficiencies, costs or expenses connected with, resulting
from or arising out of the infringement or misappropriation of any absolutely
necessary claim(s) of a patent(s) which reads on an industry standard for which
a license to such claim(s) is not available to QI on a reasonable and non-
discriminatory basis.  An absolutely necessary claim(s) of a patent(s) is a
claim(s) which is infringed by the manufacture, import, use or sale of the QI
Software DVD or Shippable Software DVD which is compliant with an industry
standard, such as the CSS Compliant standard for DVD, because the QI Software
DVD or Shippable Software DVD, solely because of the requirement to implement
the standard, cannot be manufactured, used, distributed, offered to be sold,
sold, imported and/or otherwise transferred without infringing such claim(s).
The claim of a third party patent is not an absolutely necessary claim if it
would be obvious to one ordinarily skilled in the art that the claim can be
designed around and the QI Software DVD or Shippable Software DVD would still be
compliant with the industry standard.

          (c)   Notwithstanding any provisions of the Agreement to the contrary,
and without limiting the generality of Section 9.2(b), QI will not be
responsible for the payment of any license fees with respect to any patent(s)
licensed by MPEG-LA, which license fees would be due or payable as a result of
the manufacture, use, distribution, offering for sale, sale, import or export of
any ST product or an ST Customer product.

          9.3   Requirements.  The indemnification provisions set forth herein
                ------------                                                  
are predicated on the indemnitee giving prompt written notice of any claim for
which indemnification is required, tender the defense of any such claim to the
indemnifying party, providing full cooperation for such defense at the
indemnifying party's expense, and not settling without the indemnifying party's
prior written approval, not to be unreasonably withheld.  The indemnitee may
participate in any such defense or settlement with counsel of its own choosing
at its own expense.

          9.4   Options.  If any of the software licensed hereunder becomes, or
                -------                                                        
in QI's opinion is likely to become, the subject of a claim of infringement,
then ST will permit QI, at QI's option and expense, (a) to procure for ST the
right to continue using the same under the terms of this Agreement or (b) to
replace or modify the same so that it becomes non-infringing and equivalent in
function.

          9.5   EXCLUSIVE OBLIGATIONS.  THE PROVISIONS OF THIS SECTION 9 ARE
                ---------------------                                       
QI'S EXCLUSIVE OBLIGATIONS WITH RESPECT TO INFRINGEMENT OF INTELLECTUAL PROPERTY
RIGHTS.

SECTION 10.  TRADEMARKS.
             ---------- 

          The Shippable Software DVD will incorporate ST Trademarks.  The
Shippable Software DVD incorporated on Licensed Products will also, within QI's
discretion, include QI's 

                                       12
<PAGE>
 
logo or banner on the installation screen and QI's copyright notice in the
"about" section of the program.

SECTION 11:  TERM AND TERMINATION.
             -------------------- 

             11.1  Term.  Unless otherwise terminated under this Section, this
                   ----

any time by a party for material breach of this Agreement by the other party, if
such breaching party does not cure such breach within thirty (30) days after
receiving written notice thereof. The parties acknowledge that non-payment of
royalties or other payments hereunder when due is a material breach.
Notwithstanding the foregoing, the cure period for non-payment of royalties or
other payments hereunder shall be five (5) days after receipt of written notice
of such breach.

             11.3  Termination of License Grant.  Notwithstanding any other
                   ----------------------------                            
provision of this Agreement, QI may terminate the rights and license granted to
ST under Section 4: (a) if ST has breached its payment obligations to QI, and QI
terminates the Agreement in accordance with Section 11.2 for such breaches.

             11.4  Survival. The rights and obligations contained in the
                   --------
following sections shall survive any termination or expiration of this
Agreement: Sections 3, 4 (except as provided in Section 11.3), 5, 6, 7, 8, 9,
10, 12, and 13.

             11.5  Reservation of Rights and Remedies.  Upon termination of this
                   ----------------------------------                           
Agreement for any reason, each party shall have all rights and remedies
available to it in law or in equity with respect to the other party.

SECTION 12:  CHOICE OF LAWS; CONSENT TO JURISDICTION; LIMITATION OF LIABILITY,
             ---------------------------------------------------------------- 

             12.1  Governing Law.  This Agreement shall be governed by and
                   -------------                                          
construed in accordance with the substantive laws of the State of Delaware,
U.S.A. In the event that any legal action or other proceeding is commenced to
enforce any provision of this Agreement or as a result of a breach, default or
misrepresentation in connection with any provision of this Agreement, the
successful or prevailing party shall be entitled, in addition to any other
relief which said party may be entitled, to recover reasonable attorneys' fees
and costs of litigation incurred in such action or proceeding.

            12.2  Limitation of Liability.

deficiencies, costs or expenses, including without limitation, reasonable
attorneys fees and expenses, which ST may suffer or incur connected with,

governmental and judicial action not the fault of the party failing or delaying
in performance.

SECTION 14:  NON-DISCLOSURE OF IDENTITY OF QI
             --------------------------------

             14.1  Prior to October 1, 1998, neither ST nor any Affiliate shall

in such customer's equipment or the fact that ST will be incorporating QI
software or technology in ST's products.

             14.2  ST shall not be bound by the non-disclosure obligations under
Section 14.1 to the extent that ST is required to make such a disclosure by law
or by governmental administrative order.

SECTION 15:  MISCELLANEOUS
             -------------

             15.1  Notices. Notices by either party to the other shall be given

QI is that of independent contractors, and not partners, joint ventures or

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

          2.1  Code.  Company hereby grants to Microsoft, under all Company's
               ----

to the contrary herein, Microsoft may only distribute the Code in source code
form to third parties under the following circumstances: (a) where the source
code is sublicensed to licensees of Microsoft source code as part of a Microsoft
operating system product in source code form, and such sublicensee is subject to
an agreement between Microsoft and such Microsoft license contains terms which
protect the source code of the Code to the same extent as Microsoft source code;

not to disclose the Code in source code form to the following companies that
distribute products which are competitive to Company's products: C-Cube,
Panasonic/Matsushita, and IBM; or (b) to a contractor or consultant doing work

ongoing ability to exchange Code and MS Modified Code as the need or desire
arises.  In no event shall the license grants in Section 2 of this Agreement be
construed either as an obligation on either party's part to use or distribute
the Code or MS Modified Code; or as an obligation on either party's part to
provide the other party with modifications a party may make to the MS Modified
Code and the Code.

4.   Ownership.

          4.1  Except as expressly licensed to Microsoft under Section 2.1,

     7.3.   Minimum Prepaid Royalties.  At the end of each calendar quarter
            -------------------------                                      
            during the first year of royalty payments, commencing on the date
            that Shippable Software DVD is provided to ATI by QI, ATI shall pay
            to QI, a minimum prepaid royalty payment of * . At the end of each
            three (3) month period during the second year of royalty payments,
            ATI shall pay to Quadrant, a minimum prepaid royalty of * . These
            royalties shall be credited towards the royalties earned during such
            calendar quarter. In the event that the royalties for any calendar
            quarter plus credits from previous quarters exceed the actual
            royalties earned during such calendar quarter, such excess royalties
            will be credited towards future royalties in the following calendar
            quarters. After the conclusion of the eighth quarter, ATI will not
            be required to make minimal royalty payments.

     7.4.   ATI may apply * of the minimum prepaid royalty due in each of the
            first four (4) quarters of the first year of royalty payments to
            purchase further equity in Quadrant in the form of convertible
            preferred stock and warrants such further equity shall also
            constitute prepaid royalties by ATI and shall reduce ATI's minimum
            prepaid royalty accordingly. Provided that ATI is still obligated to
            pay a minimum prepaid royalty, ATI may further apply * of the
            minimum prepaid royalty due * after ATI is first provided with a
            Shippable Software DVD to purchase further equity in Quadrant in the
            form of convertible preferred stock and warrants.

     7.5    Favoured Pricing for ATI and ATI Customers.  Under the terms of this
            ------------------------------------------                          
            Agreement, QI agrees that ATI and ATI customers shall be provided
            with a no less favourable royalty rate than QI may grant or has
            granted to any other entity. In the event that QI has licensed any
            version of its QI Software DVD at a more favorable royalty rate
            and/or on terms more favorable than those described herein, ATI
            shall be automatically entitled to the same royalty rate and/or
            terms granted by QI to the other entity.

     7.6    The parties acknowledge that there may arise situations where an OEM
            of ATI would like to incorporate QI's Accelerated Software DVD that
            is then currently subject to the ATI's Exclusivity Period in a
            product line that does not include ATI graphics technology. In such
            situations, ATI may, within its discretion, waive its right to
            exclusivity during the relevant Exclusivity Period and permit QI to
            sell that Version of QI's Accelerated Software DVD to such OEM, and
            in such event, QI will pay to ATI a reverse royalty,during the
            Exclusivity Period, equal to the lesser of: (a) * per copy of the
            Accelerated Software DVD incorporating such Version sold to the OEM
            during such Exclusivity Period, or (b) * of the license fees
            received by QI from the OEM attributable to QI's Accelerated
            Software DVD incorporating such Version that is sold during such
            Exclusivity Period. QI shall make such reverse royalty

requested by ST and may be in the form of conference calls and/or meetings
between ST and QI.

     2.3   Both Parties agree to designate an Administrative Manager, and a
Technical Manager from their respective companies.  These individuals will use
reasonable efforts in coordinating the continuing development of objectives,
related scheduling and resource allocation in respect of the provision of the
Services.

     2.4   ST may withhold acceptance of any QI Deliverables or part thereof if
it reasonably concludes that the QI Deliverable is not in material compliance
with the specifications for such QI Deliverable set forth in the Acceptance
Criteria specified in the Statement of Work and/or the specifications for such
QI Deliverable prepared by QI and which specifications were accepted by ST under
the Statement of Work or otherwise.  ST may reject any QI Deliverable or part
thereof, within (20) days after QI's delivery to ST, in accordance with the
foregoing sentence, by giving written notice to QI of such rejection and setting
forth in reasonable detail the reasons therefor, including a description of how
such QI Deliverable is not

                                       4
<PAGE>
 
in material compliance with the relevant specifications. Failure of ST to so
notify QI within the said period shall be deemed as acceptance. Upon delivery of
a rejection notice, QI shall commence work to correct the failures specified in
such notice and shall use its good faith reasonable efforts to correct such
failures in a timely fashion so that the QI Deliverable meets the relevant
specifications. When QI believes it has made the necessary corrections QI will
again deliver the QI Deliverable to ST and the acceptance/rejection/correction
provisions above shall be reapplied until the QI Deliverable is accepted;
provided, however, that upon the third or any subsequent rejection, or if the
corrections are not made within sixty (60) days of initial rejection, ST may
terminate this Contract by delivering written notice to QI. Notwithstanding the
foregoing, acceptance of a QI Deliverable shall be deemed to have occurred if ST
sells, ships, bills, and/or is paid for a product incorporating such QI
Deliverable.

shall submit in writing a "Change Request" to the other Party's Administrative

for such request.  Within fifteen (15) days (or such longer period as agreed by
the Parties) after the receipt of such Change Request, the Parties shall discuss
the necessity and/or desirability of the Change Request and the resulting,
adjustments to the Statement of Work.  When both Parties' Technical Managers
have executed the Change Request describing the Change, its implementation and
the agreed upon adjustments, QI shall commence performance in accordance with
such Change Request.  Each Change Request executed by the Parties' Technical
Manager as described above shall be incorporated into and constitute an
amendment to this Contract.

sold, shipped, billed and/or paid for, whichever occurs first. For the avoidance
of doubt, no royalty will be due to QI when the STi5505/STi5508 is sold without
any QI Deliverables embedded in the STi5505/STi5508.

     5.4  Reports.  In addition to the quarterly royalty payment described in
          -------

ST's possession or use of the software licensed hereunder or upon the grant of
the licenses contemplated by this Contract or the exercise thereof or based upon
or measured by the royalty or payment thereof or any part thereof. It is
understood and agreed that if ST is required by any governmental authority to
withhold any portion of the royalty prescribed herein and pay over such portion
to such governmental authority, then such monies retained by ST and paid over to
the governmental authority shall be deemed to be a payment by ST to QI in
satisfaction and to the extent, of that portion of ST's obligation under this
Contract, provided, however, that ST promptly furnish QI with official
government receipts as evidence of each such payment.

          (b)  If any Governmental authority requires that value added tax
("VAT") is to be levied on payments hereunder, ST will be solely responsible for
payment of said VAT levies.

properly ascertained.

more frequently than once annually during the time ST is required to make
royalty payments to QI hereunder and for one year thereafter, of all records and
accounts as may under recognized accounting practices contain information
bearing upon the QI sales revenue and the number of Products sold by ST under
this Contract.  The Auditors will report to QI only upon whether the royalties
paid to QI by ST were or were not correct, and if incorrect, what are the
correct amounts for the royalties, and the amount of time of such delinquency so
that interest due thereon may be calculated.  ST shall be supplied with a copy
of or sufficient extracts from any report prepared by the Auditors.  The
Auditors' findings shall (in the absence of clerical or manifest error) be final
and binding on the Parties.  If QI has a good faith belief that its Auditors

                                       7
<PAGE>
 
have made a clerical or manifest error, then QI shall have the right, within
thirty (30) days after the first audit, to have a second audit performed, on the
same terms and conditions set forth above, for the purpose of verifying the
accuracy of the first audit.  Such audit(s) shall be at QI's expense unless it
reveals an underpayment of royalties of five percent (5%) or more in which case
ST shall reimburse QI for the costs of such audit; provided, however, that ST
shall not be responsible in any event for bearing the cost of a second audit
that may be performed to verify the accuracy of the first audit.  ST will make

the attention of ST.  ST shall pay interest on any such payment adjustments in
accordance with Section 5.7.

from making payment of any monies at the time when the same are due and payable

SECTION 6: CUSTOMIZATIONS
- -------------------------

          If a Customer or prospective Customer requires that the Software or
other portion of the Platform be customized to meet such Customer's or
prospective Customer's requirements ("Customer Customizations"), then QI, ST,
and the Customer or prospective Customer will meet and confer in good faith to
discuss the matter, including the payment for such Customer Customizations
("Customer Customizations Payment").  Unless and until QI, ST, and the Customer
or prospective Customer reach an appropriate agreement concerning the matter, QI

     11.4  ST's Proprietary Items.  The provisions of this Section 11 shall
           ----------------------                                          
apply mutatis mutandis to the specifications and any other confidential
information provided by ST to QI.

SECTION 12: EXPORTATION OF TECHNICAL DATA OR PRODUCTS
- -----------------------------------------------------

           ST shall not, without the prior written consent of QI and the Office
of Export Administration, United States Department of Commerce, knowingly re-
export, export, or ship, or cause to be re-exported, exported, or shipped,
directly or indirectly, any software licensed hereunder, or any related
technology, or any direct or indirect product thereof, to any country to which,
under the laws of the United States, QI is or may be prohibited from exporting
its technology or its direct or indirect product.  The provisions of this
paragraph shall extend automatically to any other destination to which the U.S.
Office of Export Administration at any time during the life of this Contract
restricts or prohibits the export of technical data or any direct or indirect
product thereof.

SECTION 13: INDEMNIFICATION
- ---------------------------

     13.1  Mutual.  Each Party agrees to defend, indemnify and hold harmless the
           ------                                                               
other Party and its officers, directors, employees, agents and contractors
("Indemnitees") from and against any and all claims, actions, liabilities,
obligations, damages, losses, demands, recoveries, deficiencies, costs or
expenses, including without limitation, reasonable attorneys fees and expenses,
which an Indemnitee may suffer or incur connected with, resulting from or
arising out of such Party's breach of its representations, warranties and/or
covenants made in this Contract.

     13.2  Licensed Intellectual Property.
           ------------------------------ 

           (a)  QI agrees to defend, indemnify and hold harmless ST from and
against any and all claims, actions, liabilities, obligations, damages, losses,
demands, recoveries, deficiencies, costs or expenses, including without
limitation, reasonable attorneys fees and expenses, which ST may suffer or incur
connected with, resulting from or arising out of the infringement or
misappropriation of a third party Intellectual Property Right by QI
Deliverables.  The foregoing indemnity will not apply to any infringement or
misappropriation claim arising from (i) any modifications to QI Deliverables
wherein the claim arises as a result of such modification and the modification
was made by parties other than QI or a Person under QI's control, or (ii) any
combination of any QI Deliverables with other products or components where there
would be no infringement absent such use with such other products or components
(excluding the STi5505/STi5508 and/or other software embedded therein), or (iii)
any ST Deliverables or any portion of QI Deliverables made in whole or in part
in accordance with ST's specifications.

           (b)  Notwithstanding the foregoing, QI shall have no obligation to
defend, indemnify or hold ST or any Affiliate harmless under this Contract with
respect to any claims, actions, liabilities, obligations, damages, losses,
demands, recoveries, deficiencies, costs or expenses connected with, resulting
from or arising out of the infringement or misappropriation of any absolutely
necessary claim(s) of a patent(s) which reads on an industry standard for which
a license to such claim(s) is not available to QI on a reasonable and non-
discriminatory basis.  An absolutely necessary claim(s) of a patent(s) is a
claim(s) which is infringed by the manufacture,

                                       12
<PAGE>
 
import, use or sale of the Product which is compliant with an industry standard,
such as the CSS Compliant standard for DVD, because the Product, solely because
of the requirement to implement the standard, cannot be manufactured, used,
distributed, offered to be sold, sold, imported and/or otherwise transferred
without infringing such claim(s). The claim of a third party patent is not an
absolutely necessary claim if it would be obvious to one ordinarily skilled in
the art that the claim can be designed around and the Product would still be
compliant with the industry standard.

           (c)  Notwithstanding any provisions of the Contract to the contrary,
and without limiting the generality of Section 13.2, unless otherwise agreed and
superseded by an addendum, ST shall pay all royalties, licenses or other fees
payable to third parties which would be due or payable as a result of the
manufacture, use, distribution, offering for sale, sale, import or export of an
ST product or an ST Customer product.

     13.3  Requirements.  The indemnification provisions set forth herein are
           ------------                                                      
predicated on the indemnitee giving prompt written notice of any claim for which
indemnification is required, tender the defense of any such claim to the
indemnifying Party, providing full cooperation for such defense at the
indemnifying Party's expense, and not settling without the indemnifying Party's
prior written approval, not to be unreasonably withheld.  The indemnitee may
participate in any such defense or settlement with counsel of its own choosing
at its own expense.

     13.4  Options.  If any of the software licensed hereunder becomes, or in
           -------                                                           
QI's opinion is likely to become, the subject of a claim of infringement, then
ST will permit QI, at QI's option and expense, (a) to procure for ST the right
to continue using the same under the terms of this Contract, or (b) to replace
or modify the same so that it becomes non-infringing and equivalent in function.

     13.5  EXCLUSIVE OBLIGATIONS.  THE PROVISIONS OF THIS SECTION 13 ARE QI'S
           ---------------------                                             
EXCLUSIVE OBLIGATIONS WITH RESPECT TO INFRINGEMENT OF INTELLECTUAL PROPERTY
RIGHTS.

SECTION 14: REPRESENTATIONS AND WARRANTIES
- ------------------------------------------

     14.1  QI represents and warrants that the QI Deliverables shall meet the
technical specifications contained in Statement of Work in all material
respects.

     14.2  QI represents and warrants that it has the full right and power to
enter into this Contract and grant the licenses contained herein.

     14.3  QI represents and warrants that it has no knowledge that the QI
Deliverables infringe any Intellectual Property Right of any third party.

     14.4  ST represents and warrants that it has no knowledge that the Product

and between the 20th and 21st

                                       13
<PAGE>
 
centuries, provided that all hardware, software and firmware used in connection
with the QI Deliverable properly exchanges accurate date data with it.

     14.6  Notwithstanding any other provision of this Agreement to the
contrary, QI shall not be liable to ST for any failure or delay in performance
under this Contract, or for any breach of any representation or warranty under
this Contract to the extent that such failure, delay or breach is due to or
results from any problems, errors or deficiencies in the ST Deliverables that ST
is delivering under section 4.1 of the Statement of Work or any actual or
alleged infringement of any third party intellectual property right by ST
Deliverables under section 4.1 of the Statement of Work.

     14.7  EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN QI MAKES NO OTHER
WARRANTIES WHATSOEVER, EXPRESS OR IMPLIED, WITH REGARD TO ANY SOFTWARE LICENSED
HEREUNDER OR ANY PARTS THEREOF, AND THAT QI EXPLICITLY DISCLAIMS ALL WARRANTIES
OF MERCHANTABILITY AND OF FITNESS FOR A PARTICULAR PURPOSE.  FURTHER, QI
EXPRESSLY DOES NOT WARRANT THAT THE SOFTWARE LICENSED HEREUNDER OR ANY PARTS
THEREOF, WILL BE ERROR FREE, WILL OPERATE WITHOUT INTERRUPTION OR WILL BE
COMPATIBLE WITH ANY HARDWARE OR SOFTWARE.

SECTION 15: SOURCE CODE ESCROW
- ------------------------------

Within six (6) months of the Effective Date, QI shall escrow the source code for
the Software, together with all documentation reasonably necessary for a
programmer skilled in the art to maintain and support the Software (the
"Escrowed Materials"), with Data Securities Inc. (the "Escrow Agent"), in
accordance with a Source Code Escrow Agreement substantially in the form
attached hereto as Appendix 4 or as otherwise agreed by the Parties.  All escrow
fees shall be boure by ST.  An "Insolvency Event" shall be deemed to have
occurred if QI has availed itself of, or been subjected to by any third party, a
proceeding in bankruptcy in which QI is named debtor; an assignment by QI for
the benefit of its creditors; the appointment of a receiver for QI; or any other
proceeding involving insolvency or the protection of, or from creditors, and the
same has not been discharged or terminated without any prejudice to ST's rights
or interests under this Agreement within sixty (60) days.  An Insolvency Event
shall also be deemed to have occurred if QI does not fulfill its support
obligations under Section 9.2; or in the event that the Parties fail to reach
agreement, pursuant to Section 9.3, for support and maintenance after the
Warranty Period.  ST may give written notice by certified mail to the Escrow
Agent and QI of the occurrence of an Insolvency Event hereunder.  Unless within
fifteen (15) days thereafter QI files with the Escrow Agent its affidavit
executed by a responsible executive officer clearly refuting the alleged
Insolvency Event or showing that the Insolvency Event has been cured, then the
Escrow Agent shall upon the sixteenth (16th) day deliver to ST the Escrowed
Materials solely for ST's use in maintaining and supporting the Product and not
for any other use.

SECTION 16: CHOICE OF LAWS; CONSENT TO JURISDICTION; LIMITATION OF LIABILITY
- ----------------------------------------------------------------------------

     16.1  Governing Law.  This Contract shall be governed by and construed in
           -------------                                                      
accordance with the substantive laws of the state of New York, U.S.A. without

notice describing the dispute referred to as "Notice of Claim" shall be finally
settled by an arbitral tribunal consisting of three arbitrators appointed by the
Court of Arbitration of the International Chamber of Commerce (ICC). The
arbitration tribunal, including all staff, all witnesses, and attending non-
Parties, shall be legally bound by agreements and/or orders to prevent
disclosure of any information which may be disclosed to them in connection with
arbitration proceedings conducted hereunder. The arbitration shall take place in
New York, New York in the English language and according to the Rules of
conciliation and arbitration of the ICC. The arbitrators shall apply the laws of
the state of New York to the merits of the dispute and in all cases shall decide
in accordance with the terms of this Contract. The arbitral decision and award
shall be final and binding and shall deal with the questions of costs of
arbitration an all matters related thereto. For the avoidance of doubt, nothing

to claims for bodily injury or damage to real property for which a Party is
legally liable.

          (b) With respect to QI's obligations to indemnify, defend and hold ST
harmless under Section 13.2, in no event shall QI financial responsibility under
Section 13.2 in the aggregate exceed * ("QI's Indemnification Cap").

          (c) In no event shall either Party be liable to the other Party for
incidental damages, lost profits, lost savings, or any other consequential
damage, regardless of whether the claim is for breach of contract, warranty,
tort (including negligence), failure of a remedy to accomplish its purpose or
otherwise, even if such Party has been advised of the possibility of such
damages.  Except as stated in Section 13, neither Party shall be liable for any
damages claimed by the other Party based on any third party claim.

SECTION 17: FORCE MAJEURE
- -------------------------

     attached hereto and forms an integral part of this Agreement (for example,
     without limiting the foregoing, a continuation Application, a corresponding

     Patents.

          Applications and Patents which contain not only common subject matter
     but also additional subject matter going beyond the disclosure of
     Applications and Patents of this Section (for example, without limiting the
     foregoing, a continuation-in-part Application, or a corresponding or
     refiled Application in the nature of a continuation-in-part Application)
     shall be deemed to be Scheduled Patents only with respect to that portion
     of their subject matter common to the Applications and Patents of this

     or licensable by LICENSOR, relating to the Licensed Devices and the
     Licensed Products and all designs, drawings, reports, memoranda, blue-
     prints, specifications and the like, prepared by LICENSOR or by others and
     licensable by LICENSOR, insofar as LICENSOR deems the same to relate to and
     be useful for the development, design, manufacture, sale or use of Licensed
     Products.  Know-How does not include Licensed Copyrighted Works, whether or
     not published.

          Section 1.14 - "Confidential Information" means technical and non-
          -----------------------------------------

     licenses herein granted, are (or in the case of an Application, would be if
     it were an issued Patent) infringed by the manufacture, and/or use, lease
     or sale of such Licensed Product.

          The Licensed Trademarks have acquired a reputation for high quality
     among professionals and consumers around the world.  The performance
     capability of the Dolby Digital AC-3 audio system is such that LICENSOR is
     willing to allow the use of the Licensed Trademarks on certain Licensed
     Products and in connection with their advertising and marketing to indicate
     that the quality of such products conforms with the general reputation for
     high quality associated with the Licensed Trademarks.  LICENSEE's use of
     the Licensed Trademarks is optional, however, if LICENSEE opts to use one
     or more Licensed Trademarks, such use shall be subject to the obligations
     of this Agreement as well as detailed regulations issued from time to time
     by LICENSOR.  Detailed regulations current at the time of execution of this
     Agreement and additional to those set forth in this Agreement are set forth
     in the section entitled "Trademark Usage" in the Dolby Digital AC-3
     Licensing Information Manual of Appendix C which is attached hereto and
     forms an integral part of this Agreement.  LICENSEE shall comply with the
     requirements of the body of this Agreement and those of the Dolby Digital
     AC-3 Licensing Information Manual of Appendix C and such additional
     regulations as LICENSOR may issue and shall ensure that its subsidiaries,
     agents, distributors, and dealers throughout the world comply with such
     requirements:

          (1) LICENSEE shall prominently mark the Licensed Product on an exposed
     surface thereof in the following way:

                                 [DOLBY LOGO]

          Alternatively, if the Licensed Product is a PC or PC subsystem, the
     mark may appear as part of an opening screen or in an "about" window of the
     application software controlling the Licensed Product.

          (2) The mark specified in subsection (1) of this Section 3.01, may
     also be used at least once in a prominent manner in all advertising and
     promotions for such Licensed Product; such usages shall be no less
     prominent and in the same relative size as the most prominent third party
     trademark(s) appearing on such Licensed Product or in the advertising and
     promotion thereof.

          (3) LICENSEE may not use the Licensed Trademarks in advertising and
     promotion of a product not marked in accordance with subsection (1) of this
     Section 3.01, even if such product is a Licensed Product.

          (4) In every use of a Licensed Trademark, except on the exposed main
     control surface of a Licensed Product, LICENSEE shall give notice to the
     public that such Licensed Trademark is a trademark by using the superscript
     letters "TM" after the respective trademark, or by use of the trademark
     registration symbol "(R)" (the capital letter R enclosed in a circle) as a
     superscript after the respective trademark.  LICENSOR shall inform LICENSEE
     as to which notice form is to be used.

          (5) LICENSEE shall use its best efforts to ensure that the appropriate
     trademark notices, as set forth in subsection (3) above, appear in
     advertising for such Licensed Products at the retail level.

          (6)  LICENSOR's ownership of Licensed Trademarks shall be indicated
     whenever used by LICENSEE, whether use is on a product or on descriptive,
     instructional, advertising, or promotional material, by the most relevant
     of the following acknowledgments: "`Dolby' is a trademark of Dolby
     Laboratories", "The `Double-D' symbol is a trademark of Dolby
     Laboratories", or "'Dolby' and the `DoubleD' symbol are trademarks of Dolby
     Laboratories." On Licensed Products such words shall be used on an exposed
     surface when space permits.  LICENSEE shall use its best efforts to ensure
     that such an acknowledgment appears in advertising at the retail level.

          (7)  Licensed Trademarks shall always be used in accordance with
     established United States practices for the protection of trademark and
     service mark rights, unless the requirements in the country or jurisdiction
     in which the product will be sold are more stringent, in which case the
     practice of such country or jurisdiction shall be followed. In no event
     shall any Licensed Trademark be used in any way that suggests or connotes
     that it is a common, descriptive or generic designation. Whenever the word
     `Dolby' is used, the letter D shall be upper-case. The word `Dolby' shall
     be used only as an adjective referring to a digital audio product, never as
     a noun or in any other usage which may contribute to a generic meaning
     thereof. In descriptive, instructional, advertising, or promotional
     material or media relating to Licensed Products, LICENSEE must use the
     Licensed Trademarks and expressions which include the Licensed Trademark
     `Dolby' with an appropriate generic or descriptive term (e.g. "Dolby
     Digital decoder", "Dolby Digital audio circuit", "Dolby Digital (AC-3)
     transmission" etc.), with reference to Licensed Products and their use.

          (8)  All uses of the Licensed Trademarks are subject to approval by
     LICENSOR.  LICENSOR reserves the right to require LICENSEE to submit
     proposed uses to LICENSOR for written approval prior to actual use.  Upon
     request of LICENSOR, LICENSEE shall submit to LICENSOR samples of its own
     usage of the Licensed Trademarks and usage of the Licensed Trademarks by
     its subsidiaries, agents, distributors, and dealers.

          (9)  Licensed Trademarks shall be used in a manner that distinguishes
     them from other trademarks, service marks, symbols or trade names,
     including LICENSEE's Trade Name and Trademarks.

          (10) LICENSEE may not use the Licensed Trademarks on and in connection
     with products that do not meet LICENSOR's quality standards.

          (11) LICENSEE may not use the Licensed Trademarks on and in connection
     with products other than Licensed Products.

          Section 3.02 - Ownership of the Licensed Trademarks
          ---------------------------------------------------

          LICENSEE acknowledges the validity and exclusive ownership by LICENSOR
     of the Licensed Trademarks.

          LICENSEE further acknowledges that it owns no rights in the Licensed
     Trademarks nor in the tradename "Dolby Laboratories." LICENSEE acknowledges
     and 

                                       8
<PAGE>
 
     agrees that all rights that it may accrue in the Licensed Trademarks and in
     the tradenames "Dolby Laboratories" will inure to the benefit of the owner
     thereof, LICENSOR or LICENSOR's parent Dolby Laboratories, Inc.

          LICENSEE further agrees that it will not file any application for
     registration of the Licensed Trademarks or "Dolby Laboratories" in any
     country, region, or under any arrangement or treaty.  LICENSEE also agrees
     that it will not use nor will it file any application to register in any
     country, region, or under any arrangement or treaty any mark, symbol or
     phrase, in any language, which is confusingly similar to the Licensed
     Trademarks or "Dolby Laboratories".

          Section 3.03 - Maintenance of Trademark Rights
          ----------------------------------------------

          The expense of obtaining and maintaining Licensed Trademark
     registrations shall be borne by LICENSOR.  LICENSOR, as it deems necessary,
     will advise LICENSEE of the grant of registration of such trademarks.  Upon
     request by either party, LICENSEE and LICENSOR will comply with applicable
     laws and practices of the country of registration, including, without
     limiting the foregoing, the marking with notice of registration and the
     recording of LICENSEE as a registered or licensed user of such trademarks.
     The expense of registering or recording LICENSEE as a registered user or
     otherwise complying with the laws of any country pertaining to such
     registration or the recording of trademark agreements shall be borne by
     LICENSEE.  LICENSEE shall advise LICENSOR of all countries where Licensed
     Products are sold, leased or used.

          Section 3.04 - Patent, Trademark and Copyright Enforcement
          ----------------------------------------------------------

          LICENSEE shall immediately inform LICENSOR of all infringements,
     potential or actual, which may come to its attention, of the Patent Rights,
     Licensed Trademarks or Licensed Copyrighted Works.  It shall be the
     exclusive responsibility of LICENSOR, at its own expense, to terminate,
     compromise, or otherwise act at its discretion with respect to such
     infringements.  LICENSEE agrees to cooperate with LICENSOR by furnishing,
     without charge, except out-of-pocket expenses, such evidence, documents and
     testimony as may be required therein.

          Section 3.05 - Other-Trademark Purchasers
          -----------------------------------------

          If LICENSEE sells or leases Licensed Products on a mass basis to an
     Other-Trademark Purchaser who does not hold a license with terms and
     conditions substantially similar to this Agreement, LICENSEE shall inform
     LICENSOR of the name, place of business, trademarks, and trade names of the
     Other Trademark Purchaser before such Other-Trademark Purchaser sells,
     leases, or uses Licensed Products.  LICENSEE shall obtain agreement from
     such Other-Trademark Purchaser not to modify, install, use, lease, sell,
     provide written material for or about, advertise, or promote Licensed
     Products in any way which is in conflict with any provision of this
     Agreement.  It shall be the responsibility of LICENSEE to inform the Other-
     Trademark Purchaser of the provisions of this Agreement, to notify such
     Other-Trademark Purchaser that the provisions of this Agreement shall be
     applicable, through LICENSEE, in the same way as if the Licensed 

                                       9
<PAGE>
 
     Products were sold by LICENSEE under LICENSEE's Trade Names and Trademarks,
     to ensure by all reasonable means that such provisions are adhered to and,
     if requested by LICENSOR, to provide to LICENSOR copies of such Other-
     Trademark Purchaser's advertising, public announcements, literature,
     instruction manuals, and the like. It shall be LICENSEE's responsibility to
     inform said Other-Trademark Purchaser that any use of any of LICENSOR's
     trademarks on or in conjunction with the Other-Trademark Purchaser's own
     products can only be done under a separate license from LICENSOR.

          Section 3.06 - Patent Marking
          -----------------------------

          LICENSEE shall render statements and royalty payments as follows:

          (1) LICENSEE shall deliver to the address shown on the cover sheet of
     this Agreement or such place as LICENSOR may from time to time designate,
     quarterly reports certified by LICENSEE's chief financial officer or the
     officer's designate within 30 days after each calendar quarter ending with

     reports may be delivered by facsimile by transmitting them to LICENSOR's

     and shall be made by wire transfer in United States funds to LICENSOR's
     bank as identified on the cover sheet of this Agreement or such other bank
     as LICENSOR may from time to time designate.  LICENSEE shall pay all local
     fees, taxes, duties, or charges of any kind and shall not deduct them from

     own tax liabilities.

          Each quarterly report shall:

     calendar quarter for which the report is due shall be applied by LICENSOR
     to the next payment due.

          (4) LICENSEE shall deliver a final report and payment of royalties to
     LICENSOR certified by LICENSEE's chief financial officer or the officer's
     designate within 30 days after termination of this Agreement throughout the

     Such final report shall be supplemented at the end of the next and
     subsequent quarters, in the same manner as provided for during the Life of
     the Agreement, in the event that LICENSEE learns of any additional
     royalties due.

     Initial Payment, at the rate of 2% above the prime rate as is in effect
     from time to time at the bank identified on the cover page of this
     Agreement, or another major bank agreed to by the LICENSOR and LICENSEE in
     the event that the identified bank should cease to exist, provided however,
     that if the interest rate thus determined is in excess of rates allowable
     by any applicable law, the maximum interest rate allowable by such law
     shall apply.

          Section 4.06 - Royalties in Non-Patent Country
          ----------------------------------------------

          If a Licensed Product is manufactured in a Non-Patent Country and
     used, sold, leased or otherwise disposed of in a Non-Patent Country, be it
     the same or a different Non-Patent Country, royalties for the manufacture,
     use, sale, lease or other disposal of the Licensed Products in such Non-
     Patent Country or Countries under the Know-How, Licensed Copyrighted Works,
     and the Licensed Trademarks license shall be payable at the rates specified

     Products manufactured in a Non-Patent Country and used, sold, leased or

     consumers or for sale, lease or other

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

          LICENSEE shall keep complete books and records of all sales, leases,

     accuracy of the same and of the statements provided for herein but such
     inspection and examination shall be made during business hours upon
     reasonable notice and not more often than once per calendar year.  LICENSOR
     agrees not to divulge to third parties any Confidential Information
     obtained from the books and records of LICENSEE as a result of such
     inspection unless such information (a) was known to LICENSOR prior to its
     acquisition by LICENSOR as a result of such inspection; (b) becomes known
     to LICENSOR from sources other than directly or indirectly from LICENSEE;
     or (c) becomes a matter of public knowledge other than by breach of this
     Agreement by LICENSOR.

          LICENSEE shall provide LICENSOR with such non-confidential information
     concerning Licensed Products as it may reasonably require in performing its
     right to enforce quality standards under this Agreement.  LICENSEE will,
     upon request, provide on a loan basis to LICENSOR a reasonable number of
     samples (at least one from each product family) of Licensed Products for
     testing, together with instruction and service manuals.  If transmissions
     necessary to test Licensed Products under field operating conditions are
     not receivable at LICENSOR's San Francisco test facility, LICENSEE shall
     make available to LICENSOR, upon receipt of reasonable notice from
     LICENSOR, reasonable facilities for testing Licensed Products.  In the
     event that LICENSOR shall complain that any Licensed Product does not
     comply with LICENSOR's quality standards, excepting newly specified
     standards falling within the ninety (90) day time limit of Section 5.01, it
     shall promptly so notify LICENSEE by written communication whereupon
     LICENSEE shall within ninety (90) days suspend the lease, sale or other
     disposal of the same.

                     TERMINATION AND EFFECT OF TERMINATION
                     -------------------------------------

          Section 6.01 - Expiration of Agreement
          --------------------------------------

          Unless this Agreement already has been terminated in accordance with
     the provisions of Section 6.02, this Agreement shall terminate in all
     countries of the world upon the expiration of the last-to-expire Patent
     under the Scheduled Patents.  The Agreement is not extended by Patents in
     the Patent Rights that are not Scheduled Patents.

          Section 6.02 - Termination for Cause
          ------------------------------------

          At the option of LICENSOR, in the event that LICENSEE breaches any of
     its material obligations under this Agreement, subject to the conditions of
     Section 6.04, this Agreement shall terminate upon LICENSOR's giving sixty
     (60) days advance notice in writing, effective on dispatch of such notice,
     of such termination, giving reasons therefor to LICENSEE, provided however,
     that, if LICENSEE, within the sixty (60) day period, remedies the failure
     or default upon which such notice is based, then such notice shall not
     become effective and this Agreement shall continue in full force and
     effect.  Notwithstanding the sixty day cure period provided under the
     provisions of this Section 6.02, interest due under Section 4.05 shall
     remain payable and shall not waive, diminish, or otherwise affect any of
     LICENSOR's rights pursuant to this Section 6.02.

          Section 6.03 - Option to Terminate in a Non-Patent Country
          ----------------------------------------------------------

          Subject to the provisions of Section 6.04, unless this Agreement
     already has been terminated in accordance with the provisions of Section
     6.01 or Section 6.02, LICENSEE shall have the option to terminate its
     license under this Agreement with respect to a Non-Patent Country at any
     time after three years from the Effective Date of this Agreement.  Said
     option to terminate with respect to such country shall be effective when
     LICENSOR receives LICENSEE's written notice of its exercise of such option
     and shall be prospective only and not retroactive.

     6.02, or upon termination of the license under this Agreement with respect
     to a Non-Patent Country in accordance with the option set forth in Section
     6.03, with respect to such country only, all licenses granted by LICENSOR
     to LICENSEE under this Agreement shall terminate, all rights LICENSOR
     granted to LICENSEE shall revest in LICENSOR, and all other rights and
     obligations of LICENSOR and LICENSEE under this agreement shall terminate
     except that the following rights and obligations of LICENSOR and LICENSEE

          (6) LICENSEE's obligations to cooperate with LICENSOR with respect to
     Patent, Trademark, and Copyright enforcement under Section 3.04, with

     Products for which commitments to vendors have been made at the time of
     such termination, subject to payment of applicable royalties thereon and
     subject to said Licensed Products meeting LICENSOR's quality standards,
     provided that LICENSEE promptly advises LICENSOR of such commitments upon
     termination; and

                                       17

                      LIMITATIONS OF RIGHTS AND AUTHORITY
                      -----------------------------------

          Section 7.01 - Limitation of Rights
          -----------------------------------

          No right or title whatsoever in the Patent Rights, Know-How, Licensed
     Copyrighted Works, or the Licensed Trademarks is granted by LICENSOR to
     LICENSEE or shall be taken or assumed by LICENSEE except as is specifically
     laid down in this Agreement.

          Section 7.02 - Limitation of Authority
          --------------------------------------

          Neither party shall in any respect whatsoever be taken to be the agent
     or representative of the other party and neither party shall have any
     authority to assume any obligation for or to commit the other party in any
     way.

          Section 7.03 - Disclaimer of Warranties and Liability: Hold Harmless
          --------------------------------------------------------------------

          LICENSOR has provided LICENSEE the rights and privileges contained in
     this Agreement in good faith.  LICENSOR represents that it has done
     diligent U.S. patentability searches in the field of digital audio and that
     it is unaware of any patents of third parties which would be infringed by
     the practice of its AC-3 digital audio technology which is the subject of
     this Agreement.  LICENSOR represents that the Licensed Know-How and
     Licensed Copyrighted Works were either developed by LICENSOR or by a third
     party from whom LICENSOR has obtained the right to license.  However,
     nothing contained in this Agreement shall be construed as (1) a warranty or
     representation by LICENSOR as to the validity or scope of any Patent
     included in The Patent Rights; (2) a warranty or representation that the
     Dolby Digital AC-3 Audio System technology, Patent Rights, Know-How,
     Licensed Copyrighted Works, Licensed Trademarks, or any Licensed Device,
     Licensed Product, or part thereof embodying any of them will be free from
     infringement of Patents, copyrights, trademarks, service marks, or other
     proprietary rights of third parties; or (3) an agreement to defend LICENSEE
     against actions or suits of any nature brought by any third parties.

          LICENSOR disclaims all liability and responsibility for property
     damage, personal injury, and consequential damages, whether or not
     foreseeable, that may result from the manufacture, use, lease, or sale of
     Licensed Devices, Licensed Products and parts thereof, and LICENSEE agrees
     to assume all liability and responsibility for all such 

                                       18
<PAGE>
 
     damage and injury, to the extent that such liability and responsibility of
     LICENSEE have been finally determined in any court of competent
     jurisdiction.

          LICENSEE agrees to indemnify, defend, and hold LICENSOR harmless from
     and against all claims (including, without limitation, product liability
     claims), suits, losses and damages, including reasonable attorneys' fees
     and any other expenses incurred in investigation and defense, arising out
     of LICENSEE's manufacture, use, lease, or sale of Licensed Devices,
     Licensed Products, or parts thereof, or out of any allegedly unauthorized
     use of any trademark, service mark, Patent, copyright, process, idea,
     method, or device (excepting Licensed Trademarks, Patent Rights, Know-How,
     Confidential Information, and Licensed Copyrighted Works) by LICENSEE or
     those acting under its apparent or actual authority.

          Section 7.04 - Limitation of Assignment by LICENSEE
          ---------------------------------------------------

          The rights, duties and privileges of LICENSEE hereunder shall not be
     transferred or assigned by it either in part or in whole without prior
     written consent of LICENSOR.  However, LICENSEE shall have the right to
     transfer its rights, duties and privileges under this Agreement in
     connection with its merger and consolidation with another firm or the sale
     of its entire business to another person or firm, provided that such person
     or firm shall first have agreed with LICENSOR to perform the transferring
     party's obligations and duties hereunder.

          Section 7.05 - Compliance with U.S. Export Control Regulations
          --------------------------------------------------------------

          (1) LICENSEE agrees not to export any technical data acquired from
     LICENSOR under this Agreement, nor the direct product thereof, either
     directly or indirectly, to any country in contravention of United States
     law.

          (2) Nothing in this Agreement shall be construed as requiring LICENSOR
     to export from the United States, directly or indirectly, any technical
     data or any commodities to any country in contravention of United States
     law.

                                  ARTICLE VIII

<PAGE>
 
     which may be inconsistent herewith, or otherwise, except by a subsequent
     agreement in writing signed by LICENSOR and LICENSEE. No waiver of a breach
     committed by either party in one instance shall constitute a waiver or a
     license to commit or continue breaches in other or like instances.

          Section 8.03 - Public Announcements
          -----------------------------------

          Neither party shall at any time heretofore or hereafter publicly state
     or imply that the terms specified herein or the relationships between

     down in this Agreement.  LICENSEE shall not at any time publicly state or
     imply that any unlicensed products use the Dolby Digital AC-3 Audio System
     Specifications.  If requested by one party, the other party shall promptly
     supply the first party with copies of all public statements and of all
     publicity and promotional material relating to this Agreement, the Dolby
     Digital AC-3 Audio System Specifications, Licensed Devices, Licensed
     Products, Licensed Trademarks, and Know-How.

               "D" - Estoppel Certificate Form

2.  PREMISES.  Landlord hereby leases to Tenant and Tenant hereby leases from
    --------                                                                 
Landlord the Premises as shown on attached Exhibit "A" within the Building (the
Building and the lot on which it is located, the "PROPERTY"), together with the
nonexclusive right with Landlord and other occupants of the Building to use all
areas and facilities provided by Landlord for the use of all tenants in the
Property including any driveways, sidewalks and parking, loading and landscaped
areas (the "COMMON AREAS").

3.  ACCEPTANCE OF PREMISES.  Tenant has examined and knows the condition of the
    ----------------------                                                     
Property, the zoning, streets, sidewalks, parking areas, curbs and access ways
adjoining it, visible easements, any surface conditions and the present uses,
and Tenant accepts them in the condition in which they now are, without relying
on any representation, covenant or warranty by Landlord.  Tenant and its agents
shall have the right, at Tenant's own risk, expense and responsibility, at all
reasonable times prior to the Commencement Date, to enter the Premises for the
purpose of taking measurements and installing its furnishings and equipment;
provided that the Premises are vacant and Tenant obtains Landlord's prior
written consent.

4.  USE; COMPLIANCE.
    --------------- 

    (a) PERMITTED USE. Tenant shall occupy and use the Premises for and only for
the Use specified in Section l(f) above and in such a manner as is lawful,
reputable and will not create any nuisance or otherwise interfere with any other
tenant's normal operations or the management of the Building. Without limiting
the foregoing, such Use shall exclude any use that would cause the Premises or
the Property to be deemed a "place of public accommodation" under the Americans
with Disabilities Act (the "ADA") as further described in the Building Rules
(defined below). All Common Areas shall be subject to Landlord's exclusive
control and management at all times. Tenant shall not use or permit the use of
any portion of the Property

                                       2
<PAGE>
 
for outdoor storage or installations outside of the Premises nor for any use
that would interfere with any other person's use of any portion of the Property
outside of the Premises.

    (b) COMPLIANCE.  Landlord represents that, as of the date of this lease,
there is no action required with respect to the Premises or Common Areas under
any laws (including Title III of the ADA), ordinances, notices, orders, rules,
regulations and requirements applicable to the Premises or to the Common Areas.
From and after the Commencement Date, Tenant shall comply promptly, at its sole
expense, (including making any alterations or improvements) with all laws
(including the ADA), ordinances, notices, orders, rules, regulations and
requirements regulating the Property during the Term which impose any duty upon
Landlord or Tenant with respect to Tenant's use, occupancy or alteration of, or
Tenant's installations in or upon, the Property including the Premises, (as the
same may be amended, the "LAWS AND REQUIREMENTS") and the building rules
attached as Exhibit "C", as amended by Landlord from time to time (the "BUILDING
RULES").  Provided, however, that Tenant shall not be required to comply with
the Laws and Requirements with respect to the footings, foundations, structural
steel columns and girders forming a part of the Property unless the need for
such compliance arises out of Tenant's use, occupancy or alteration of the
Property, or by any act or omission of Tenant or any employees, agents,
contractors, licensees or invitees ("AGENTS") of Tenant.  With respect to
Tenant's obligations as to the Property, other than the Premises, at Landlord's
option and at Tenant's expense, Landlord may comply with any repair, replacement
or other construction requirements of the Laws and Requirements and Tenant shall
pay to Landlord all costs thereof as additional rent.

    (c) ENVIRONMENTAL.  Tenant shall comply, at its sole expense, with all Laws
and Requirements as set forth above, all manufacturers' instructions and all
requirements of insurers relating to the treatment, production, storage,
handling, transfer, processing, transporting, use, disposal and release of
hazardous substances, hazardous mixtures, chemicals, pollutants, petroleum
products, toxic or radioactive matter (the "RESTRICTED ACTIVITIES").  Tenant
shall deliver to Landlord copies of all Material Safety Data Sheets or other
written information prepared by manufacturers, importers or suppliers of any
chemical and all notices, filings, permits and any other written communications
from or to Tenant and any entity regulating any Restricted Activities.

    (d) NOTICE.  If at any time during or after the Term, Tenant becomes aware
of any inquiry, investigation or proceeding regarding the Restricted Activities
or becomes aware of any claims, actions or investigations regarding the ADA,
Tenant shall give Landlord written notice, within 5 days after first learning
thereof, providing all available information and copies of any notices.

5.  TERM.  The Term of this lease shall commence on the Commencement Date and
    ----                                                                     
shall end at 11:59 p.m. on the last day of the Term (the "EXPIRATION DATE"),
without the necessity for notice from either party, unless sooner terminated in
accordance with the terms hereof.  At Landlord's request, Tenant shall confirm
the Commencement Date and Expiration Date by executing a lease commencement
certificate in the form attached as Exhibit "B".

6.  MINIMUM ANNUAL RENT.  Tenant agrees to pay to Landlord the Minimum Annual
    -------------------                                                      
Rent in equal monthly installments in the amount set forth in Section 1(d) (as
increased at the 

                                       3
<PAGE>
 
beginning of each lease year as set forth in Section l(d)), in advance, on the
first date of each calendar month during the Term, without notice, demand or
setoff, at Landlord's address designated at the beginning of this lease unless
Landlord designates otherwise; provided that rent for the first full month shall
be paid at the signing of this lease. If the Commencement Date falls on a day
other than the first day of a calendar month, the rent shall be apportioned pro
rata on a per diem basis for the period from the Commencement Date until the
first day of the following calendar month and shall be paid on or before the
Commencement Date. As used in this lease, the term "LEASE YEAR" means the period
from the Commencement Date through the succeeding 12 full calendar months
(including for the first lease year any partial month from the Commencement Date
until the first day of the first full calendar month) and each successive 12
month period thereafter during the Term.

7.  OPERATION OF PROPERTY; PAYMENT OF EXPENSES.
    ------------------------------------------ 

    (a) PAYMENT OF OPERATING EXPENSES.  Tenant shall pay to Landlord the Annual
Operating Expenses in equal monthly installments in the amount set forth in
Section l(d) (prorated for any partial month), from the Commencement Date and
continuing throughout the Term on the first day of each calendar month during
the Term, as additional rent, without notice, demand or setoff, provided that
the monthly installment for the first full month shall be paid at the signing of
this lease. Landlord shall apply such payments to the operating expenses owed to
Landlord by Tenant pursuant to the following Sections 7(b)-(f). The amount of
the Annual Operating Expenses set forth in Section l(d) represents Tenant's
Proportionate Share of the estimated operating expenses during the first
calendar year of the Term on an annualized basis; from time to time Landlord may
adjust such estimated amount if the estimated operating expenses increase. By
April 30th of each year (and as soon as practical after the expiration or
termination of this lease or at any time in the event of a sale of the
Property), Landlord shall provide Tenant with a statement of the actual amount
of such expenses for the preceding calendar year or part thereof. Landlord or
Tenant shall pay to the other the amount of any deficiency or overpayment then
due from one to the other or, at Landlord's option, Landlord may credit Tenant's
account for any overpayment. Tenant's obligation to pay the Annual Operating
Expenses pursuant to this Section 7 shall survive the expiration or termination
of this lease.

    (b) TAXES AND OTHER IMPOSITIONS.  Tenant shall pay prior to delinquency all
levies, taxes (including sales taxes and gross receipt taxes), assessments,
liens, license and permit fees, which are applicable to the Term, and which are
imposed by any authority or under any law, ordinance or regulation thereof, or
pursuant to any recorded covenants or agreements, and the reasonable cost of
contesting any of the foregoing (the "IMPOSITIONS") upon or with respect to the
Premises, or any improvements thereto, or directly upon this lease or the Rent
(defined in Section 7(f)) or amounts payable by any subtenants or other
occupants of the Premises, or against Landlord because of Landlord's estate or
interest herein.  Accordingly, Tenant shall pay as aforesaid its Proportionate
Share of any Imposition which is not imposed upon the Premises as a separate
entity but which is imposed upon all or part of the Property or upon the leases
or rents relating to the Property.

        (i) Nothing herein contained shall be interpreted as requiring Tenant to
     pay any income, excess profits or corporate capital stock tax imposed or
     assessed upon

                                       4
<PAGE>
 
     Landlord, unless such tax or any similar tax is levied or assessed in lieu
     of all or any part of any Imposition or an increase in any Imposition.

          (ii)    If it shall not be lawful for Tenant to reimburse Landlord for
     any of the Impositions, the Minimum Annual Rent shall be increased by the
     amount of the portion of such Imposition allocable to Tenant, unless
     prohibited by law.

     (c)  INSURANCE.

          (i)     PROPERTY. Landlord shall keep in effect, and Tenant shall pay
     to Landlord its Proportionate Share of the cost of, insurance against loss
     or damage to the Building or the Property by fire and such other casualties
     as may be included within fire, extended coverage and special form
     insurance covering the full replacement cost of the Building (but excluding
     coverage of Tenant's personal property in, and any alterations by Tenant
     to, the Premises), and such other insurance as Landlord may reasonably deem
     appropriate or as may be required from time-to-time by any mortgagee.

          (ii)    LIABILITY.  Tenant, at its own expense, shall keep in effect
     comprehensive general public liability insurance with respect to the
     Premises and the Property, including contractual liability insurance, with
     such limits of liability for bodily injury (including death) and property
     damage as reasonably may be required by Landlord from time-to-time, but not
     less than a combined single limit of $1,000,000 per occurrence and a
     general aggregate limit of not less than $3,000,000 (which aggregate limit
     shall apply separately to each of Tenant's locations if more than the
     Premises); however, such limits shall not limit the liability of Tenant
     hereunder. The policy of comprehensive general public liability insurance
     also shall name Landlord and Landlord's agent as insured parties with
     respect to the Premises, shall be written on an "occurrence" basis and not
     on a "claims made" basis, shall provide that it is primary with respect to
     any policies carried by Landlord and that any coverage carried by Landlord
     shall be excess insurance, shall provide that it shall not be cancelable or
     reduced without at least 30 days prior written notice to Landlord and shall
     be issued in form satisfactory to Landlord. The insurer shall be a
     responsible insurance carrier which is authorized to issue such insurance
     and licensed to do business in the state in which the Property is located
     and which has at all times during the Term a rating of no less than A VII
     in the most current edition of Best's Insurance Reports. Tenant shall
     deliver to Landlord on or before the Commencement Date, and subsequently
     renewals of, a certificate of insurance evidencing such coverage and the
     waiver of subrogation described below.

          (iii)   WAIVER OF SUBROGATION. Landlord and Tenant shall have included
     in their respective property insurance policies waivers of their respective
     insurers' right of subrogation against the other party. If such a waiver
     should be unobtainable or unenforceable, then such policies of insurance
     shall state expressly that such policies shall not be invalidated if,
     before a casualty, the insured waives the right of recovery against any
     party responsible for a casualty covered by the policy.

          (iv)    INCREASE OF PREMIUMS. Tenant agrees not to do anything or fail
     to do anything which will increase the cost of Landlord's insurance or
     which will prevent

                                       5
<PAGE>
 
     Landlord from procuring policies (including public liability) from
     companies and in a form satisfactory to Landlord. If any breach of the
     preceding sentence by Tenant causes the rate of fire or other insurance to
     be increased, Tenant shall pay the amount of such increase as additional
     rent promptly upon being billed.

     (d)    REPAIRS AND MAINTENANCE; COMMON AREAS; BUILDING MANAGEMENT. Except
as specifically otherwise provided in this Section (d), Tenant at its sole
expense shall maintain the Premises in good order and condition, promptly make
all repairs necessary to maintain such condition, and repair any damage to the
Premises caused by Tenant or its Agents. All repairs made by Tenant shall
utilize materials and equipment which are comparable to those originally used in
constructing the Building and Premises. When used in this Section (d), the term
"repairs" shall include replacements and renewals when necessary.

            (i)    Landlord, at its sole expense, shall make all necessary
     repairs to the footings, foundations, structural steel columns and girders
     forming a part of the Premises, provided that Landlord shall have no
     responsibility to make any repair until Landlord receives written notice of
     the need for such repair.

            (ii)   Landlord, at Tenant's sole expense, shall maintain and repair
     the HVAC systems appurtenant to the Premises.

            (iii)  Landlord shall make all necessary repairs to the roof,
     exterior portions of the Premises and the Building, utility and
     communications lines, equipment and facilities in the Building, which serve
     more than one tenant, and to the Common Areas, the cost of which shall be
     an operating expense of which Tenant shall pay its Proportionate Share,
     provided that Landlord shall have no responsibility to make any repair
     until Landlord receives written notice of the need for such repair.
     Landlord shall operate and manage the Property and shall maintain all
     Common Areas and any paved areas appurtenant to the Property in a clean and
     orderly condition. Landlord reserves the right to make alterations to the
     Common Areas from time to time. Operating expenses also shall include (A)
     all sums expended by Landlord for the supervision, maintenance, repair,
     replacement and operation of the Common Areas (including the costs of
     utility services), (B) any costs of building improvements made by Landlord
     to the Property that are required by any governmental authority or for the
     purpose of reducing operating expenses and (C) a management and
     administrative fee applicable to the overall operation of the Property.

            (iv)   Notwithstanding anything herein to the contrary, repairs and
     replacements to the Property including the Premises made necessary by
     Tenant's use, occupancy or alteration of, or Tenant's installation in or
     upon the Property or by any act or omission of Tenant or its Agents shall
     be made at the sole expense of Tenant to the extent not covered by any
     applicable insurance proceeds paid to Landlord.  Tenant shall not bear the
     expense of any repairs or replacements to the Property arising out of or
     caused by, any other tenant's use, occupancy or alteration of, or any other
     tenant's installation in or upon, the Property or by any act or omission of
     any other tenant or any other tenant's Agents.

heat, power, telephone and other communication services and any other utilities

affect the continuation or validity of this lease.

     (f)  NET LEASE. Except for the obligations of Landlord expressly set forth
herein, this lease is a "triple net lease" and Landlord shall receive the
Minimum Annual Rent as net income from the Premises, not diminished by any
expenses other than payments under any mortgages, and Landlord is not and shall
not be required to render any services of any kind to Tenant. The term "RENT" as
used in this lease means the Minimum Annual Rent, Annual Operating Expenses and
any other additional rent or sums payable by Tenant to Landlord pursuant to this
lease, all of which shall be deemed rent for purposes of Landlord's rights and
remedies with respect thereto. Tenant shall pay all Rent to Landlord within 30
days after Tenant is billed, unless otherwise provided in this lease, and
interest shall accrue on all sums due but unpaid.

8.   SIGNS. Except for signs which are located wholly within the interior of the

Premises and not visible from the exterior of the Premises, no signs shall be
placed on the Property without the prior written consent of Landlord. All signs
installed by Tenant shall be maintained by Tenant in good condition and Tenant
shall remove all such signs at the termination of this lease and shall repair
any damage caused by such installation, existence or removal.

9.   ALTERATIONS AND FIXTURES.
     ------------------------ 

     (a)  Subject to Section 10, Tenant shall have the right to install its
trade fixtures in the Premises, provided that no such installation or removal
thereof shall affect any structural portion of the Property nor any utility
lines, communications lines, equipment or facilities in the Building serving any
tenant other than Tenant. At the expiration or termination of this lease and at
the option of Landlord or Tenant, Tenant shall remove such installation(s) and,
in the event of such removal, Tenant shall repair any damage caused by such
installation or removal; if Tenant, with Landlord's written consent, elects not
to remove such installation(s) at the expiration or termination of this lease,
all such installations shall remain on the Property and become the property of
Landlord without payment by Landlord.

     (b)  Except for non-structural changes which do not exceed $5,000 in the
aggregate, Tenant shall not make or permit to be made any alterations to the
Premises without Landlord's prior written consent. Tenant shall pay the costs of
any required architectural engineering reviews. In making any alterations, (i)
Tenant shall deliver to Landlord the plans, specifications and necessary
permits, together with certificates evidencing that Tenant's contractors and
subcontractors have adequate insurance coverage naming Landlord and Landlord's
agent as additional insureds, at least 10 days prior to commencement thereof,
(ii) such alterations shall not impair the structural strength of the Building
or any other improvements or reduce the value of the Property or affect any
utility lines, communications lines, equipment or facilities in the Building
serving any tenant other than Tenant, (iii) Tenant shall comply with Section 10
and (iv) the occupants of the Building and of any adjoining property shall not
be disturbed thereby. All alterations to the Premises by Tenant shall be the
property of Tenant until the expiration or termination of this lease at that
time all such alterations shall remain on the Property and become the property
of Landlord without payment by Landlord unless Landlord gives written notice to

                                       7
<PAGE>
 
Tenant to remove the same, in which event Tenant will remove such alterations
and repair any resulting damage. At Tenant's request prior to Tenant making any
alterations, Landlord shall notify Tenant in writing, whether Tenant is required
to remove such alterations at the expiration or termination of this lease.

10.   MECHANICS' LIENS.  Tenant shall pay promptly any contractors and
materialmen who supply labor, work or materials to Tenant at the Property and
shall take all steps permitted by law in order to avoid the imposition of any
mechanic's lien upon all or any portion of the Property.  Should any such lien
or notice of lien be filed for work performed for Tenant other than by Landlord,
Tenant shall bond against or discharge the same within 5 days after Tenant has
notice that the lien or claim is filed regardless of the validity of such lien
or claim.  Nothing in this lease is intended to authorize Tenant to do or cause
any work to be done or materials to be supplied for the account of Landlord, all
of the same to be solely for Tenant's account and at Tenant's risk and expense.
Throughout this lease the term "MECHANIC'S LIEN" is used to include any lien,
encumbrance or charge levied or imposed upon all or any portion of, interest in
or income from the Property on account of any mechanic's, laborer's,
materialman's or construction lien or arising out of any debt or liability to or
any claim of any contractor, mechanic, supplier, materialman or laborer and
shall include any mechanic's notice of intention to file a lien given to
Landlord or Tenant, any stop order given to Landlord or Tenant, any notice of
refusal to pay naming Landlord or Tenant and any injunctive or equitable action
brought by any person claiming to be entitled to any mechanic's lien.

11.   LANDLORD'S RIGHT OF ENTRY.  Tenant shall permit Landlord and its Agents to
      -------------------------                                                 
enter the Premises at all reasonable times following reasonable notice (except
in the event of an emergency), for the purpose of inspection, maintenance or
making repairs, alterations or additions as well as to exhibit the Premises for
the purpose of sale or mortgage and, during the last 12 months of the Term, to
exhibit the Premises to any prospective tenant.  Landlord will make reasonable
efforts not to inconvenience Tenant in exercising the foregoing rights, but
shall not be liable for any loss of occupation or quiet enjoyment thereby
occasioned.

12.   DAMAGE BY FIRE OR OTHER CASUALTY.
      -------------------------------- 

      (a)   If the Premises or Building shall be damaged or destroyed by fire or
other casualty, Tenant promptly shall notify Landlord and Landlord, subject to
the conditions set forth in this Section 12, shall repair such damage and
restore the Premises to substantially the same condition in which they were
immediately prior to such damage or destruction, but not including the repair,
restoration or replacement of the fixtures or alterations installed by Tenant.
Landlord shall notify Tenant in writing, within 30 days after the date of the
casualty, if Landlord anticipates that the restoration will take more than 180
days from the date of the casualty to complete, in such event, either Landlord
or Tenant may terminate this lease effective as of the date of casualty by
giving written notice to the other within 10 days after Landlord's notice.
Further, if a casualty occurs during the last 12 months of the Term or any
extension thereof,  Landlord may cancel this lease unless Tenant has the right
to extend the Term for at least 3 more years and does so within 30 days after
the date of the casualty.

      (b)   Landlord shall maintain a 12 month rental coverage endorsement or
other comparable form of coverage as Part of its fire, extended coverage and
special form insurance.

                                       8
<PAGE>
 
Tenant will receive an abatement of its Minimum Annual Rent and Annual Operating
Expenses to the extent the Premises are rendered untenantable as determined by
the carrier providing the rental coverage endorsement.

13.   CONDEMNATION.
      ------------ 

      (a)   TERMINATION. If (i) all of the Premises are taken by a condemnation
or otherwise for any public or quasi-public use, (ii) any part of the Premises
is so taken and the remainder thereof is insufficient for the reasonable
operation of Tenant's business or (iii) any of the Property is so taken, and, in
Landlord's opinion, it would be impractical or the condemnation proceeds are
insufficient to restore the remainder of the Property, then this lease shall
terminate and all unaccrued obligations hereunder shall cease as of the day
before possession is taken by the condemnor.

      (b)   PARTIAL TAKING.  If there is a condemnation and this lease has not
been terminated pursuant to this Section, (i) Landlord shall restore the
Building and the improvements which are a part of the Premises to a condition
and size as nearly comparable as reasonably possible to the condition and size
thereof immediately prior to the date upon which the condemnor took possession
and (ii) the obligations of Landlord and Tenant shall be unaffected by such
condemnation except that there shall be an equitable abatement of the Minimum
Annual Rent according to the rental value of the Premises before and after the
date upon which the condemnor took possession and/or the date Landlord completes
such restoration.

      (c)   AWARD.  In the event of a condemnation affecting Tenant, Tenant
shall have the right to make a claim against the condemnor for moving expenses
and business dislocation damages to the extent that such claim does not reduce
the sums otherwise payable by the condemnor to Landlord. Except as aforesaid and
except as set forth in (d) below, Tenant hereby assigns all claims against the
condemnor to Landlord.

      (d)   TEMPORARY TAKING.  No temporary taking of the Premises shall
terminate this lease or give Tenant any right to any rental abatement. Such a
temporary taking will be treated as if Tenant had sublet the Premises to the
condemnor and had assigned the proceeds of the subletting to Landlord to be
applied on account of Tenant's obligations hereunder. Any award for such a
temporary taking during the Term shall be applied first, to Landlord's costs of
collection and, second, on account of sums owing by Tenant hereunder, and if
such amounts applied on account of sums owing by Tenant hereunder should exceed
the entire amount owing by Tenant for the remainder of the Term, the excess will
be paid to Tenant.

14.   NON-ABATEMENT OF RENT. Except as otherwise expressly provided as to damage
      ---------------------
by fire or other casualty in Section 12(b) and as to condemnation in Section
13(b), there shall be no abatement or reduction of the Rent for any cause
whatsoever, and this lease shall not terminate, and Tenant shall not be entitled
to surrender the Premises.

15.   INDEMNIFICATION OF LANDLORD.  Subject to Sections 7(c)(iii) and 16, Tenant
      ---------------------------                                               
will protect, indemnify and hold harmless Landlord and its Agents from and
against any and all claims, actions, damages, liability and expense (including
fees of attorneys, investigators and experts) in connection with loss of life,
personal injury or damage to property in or about the Premises or 

                                       9
<PAGE>
 
arising out of the occupancy or use of the Premises by Tenant or its Agents or
occasioned wholly or in part by any act or omission of Tenant or its agents,
whether prior to, during or after the Term, except to the extent such loss,
injury or damage was caused by the negligence of Landlord or its Agents. In case
any action or proceeding is brought against Landlord and/or its Agents by reason
of the foregoing, Tenant, at its expense, shall resist and defend such action or
proceeding, or cause the same to be resisted and defended by counsel (reasonably
acceptable to Landlord and its Agents) designated by the insurer whose policy
covers such occurrence or by counsel designated by Tenant and approved by
Landlord and its Agents. Tenant's obligations pursuant to this Section 15 shall
survive the expiration or termination of this lease.

16.  WAIVER OF CLAIMS.  Landlord and Tenant each hereby waives all claims for
     ----------------                                                        
recovery against the other for any loss or damage which may be inflicted upon
the property of such party even if such loss or damage shall be brought about by
the fault or negligence of the other party or its Agents' provided, however,
that such waiver by Landlord shall not be effective with respect to any
liability of Tenant described in Sections 4(c) and 7(d)(iv).

17.  QUIET ENJOYMENT.  Landlord covenants that Tenant, upon performing all of
     ---------------                                                         
its covenants, agreements and conditions of this lease, shall have quiet and
peaceful possession of the Premises as against anyone claiming by or through
Landlord, subject, however, to the exceptions, reservations and conditions of
this lease.

18.  ASSIGNMENT AND SUBLETTING.
     ------------------------- 

     (a)  LIMITATION.  Tenant shall not transfer this lease, voluntarily or
by operation of law, without the prior written consent of Landlord which shall
not be withheld unreasonably.  However, Landlord's consent shall not be required
in the event of any transfer by Tenant to an affiliate of Tenant which is at
least as creditworthy as Tenant as of the date of this lease and provided Tenant
delivers to Landlord the instrument described in Section (c)(iii) below,
together with a certification of such creditworthiness by Tenant and such
affiliate.  Any transfer not in conformity with this Section 18 shall be void at
the option of Landlord and Landlord may exercise any or all of its rights under
Section 23.  A consent to one transfer shall not be deemed to be a consent to
any subsequent transfer.  "Transfer" shall include any sublease, assignment,
license or concession agreement, change in ownership or control of Tenant,
mortgage or hypothecation of this lease or Tenant's interest therein or in all
or a portion of the Premises.

     (b)  OFFER TO LANDLORD.  Tenant acknowledges that the terms of this lease,
including the Minimum Annual Rent, have been based on the understanding that
Tenant physically shall occupy the Premises for the entire Term.  Therefore,
upon Tenant's request to transfer all or a portion of the Premises, at the
option of Landlord, Tenant and Landlord shall execute an amendment to this lease
removing such space from the Premises, Tenant shall be relieved of any liability
with respect to such space and Landlord shall have the right to lease such space
to any party, including Tenant's proposed transferee.

     (c)  CONDITIONS.  Notwithstanding the above, the following shall apply to
any transfer, with or without Landlord's consent:

                                       10
<PAGE>
 
          (i)    As of the date of any transfer, Tenant shall not be in default
     under this lease nor shall any act or omission have occurred which would
     constitute a default with the giving of notice and/or the passage of time.

          (ii)   No transfer shall relieve Tenant of its obligation to pay the
     Rent and to perform all its other obligations hereunder.  The acceptance of
     Rent by Landlord from any person shall not be deemed to be a waiver by
     Landlord of any provision of this lease or to be a consent to any transfer.

          (iii)  Each transfer shall be by a written instrument in form and
     substance satisfactory to Landlord which shall (A) include an assumption of
     liability by any transferee of all Tenant's obligations and the
     transferee's ratification of and agreement to be bound by all the
     provisions of this lease, (B) afford Landlord the right of direct action
     against the transferee pursuant to the same remedies as are available to
     Landlord against Tenant and (C) be executed by Tenant and the transferee.

          (iv)   Tenant shall pay, within 10 days of receipt of an invoice which
     shall be no less than $250, Landlord's reasonable attorneys' fees and costs
     in connection with the review, processing and documentation of any transfer
     for which Landlord's consent is requested.

19.  SUBORDINATION; MORTGAGEE'S RIGHTS.
     --------------------------------- 

     (a)  This lease shall be subordinate to any first mortgage or other primary
encumbrance now or hereafter affecting the Premises.  Although the subordination
is self-operative, within 10 days after written request, Tenant shall execute
and deliver any further instruments confirming such subordination of this lease
and any further instruments of attornment that may be desired by any such
mortgagee or Landlord.  However, any mortgagee may at any time subordinate its
mortgage to this lease, without Tenant's consent, by giving written notice to
Tenant, and thereupon this lease shall be deemed prior to such mortgage without
regard to their respective dates of execution and delivery; provided, however,
that such subordination shall not affect any mortgagee's right to condemnation
awards, casualty insurance proceeds, intervening liens or any right which shall
arise between the recording of such mortgage and the execution of this lease.

     (b)  It is understood and agreed that any mortgagee shall not be liable to
Tenant for any funds paid by Tenant to Landlord unless such funds actually have
been transferred to such mortgagee by Landlord.

     (c)  Notwithstanding the provisions of Sections 12 and 13 above, Landlord's
obligation to restore the Premises after a casualty or condemnation shall be
subject to the consent and prior rights of Landlord's first mortgagee.

20.  RECORDING; TENANT'S CERTIFICATE.  Tenant shall not record this lease or a
     -------------------------------                                          
memorandum thereof without Landlord's prior written consent.  Within 10 days
after Landlord's written request from time to time:

                                       11
<PAGE>
 
     (a)  Tenant shall execute, acknowledge and deliver to Landlord a written
statement certifying the Commencement Date and Expiration Date of this lease,
that this lease is in full force and effect and has not been modified and
otherwise as set forth in the form of estoppel certificate attached as Exhibit
"D" or with such modifications as may be necessary to reflect accurately the
stated facts and/or such other certifications as may be requested by a mortgagee
or purchaser.  Tenant understands that its failure to execute such documents may
cause Landlord serious financial damage by causing the failure of a financing or
sale transaction.

     (b)  Tenant shall furnish to Landlord, Landlord's mortgagee, prospective
mortgagee or purchaser reasonably requested financial information.

21.  SURRENDER; ABANDONED PROPERTY.
     ----------------------------- 

     (a)  Subject to the terms of Sections 9(b), 12(a) and 13(b), at the
expiration or termination of this lease, Tenant promptly shall yield up in the
same condition, order and repair in which they are required to be kept
throughout the Term, the Premises and all improvements thereto, and all fixtures
and equipment servicing the Building, ordinary wear and tear excepted.

     (b)  Upon or prior to the expiration or termination of this lease, Tenant
shall remove any personal property from the Property.  Any personal property
remaining thereafter shall be deemed conclusively to have been abandoned, and
Landlord at Tenant's expense, may remove, store, sell or otherwise dispose of
such property in such manner as Landlord may see fit and/or Landlord may retain
such property as its property.  If any part thereof shall be sold, then Landlord
may receive and retain the proceeds of such sale and apply the same, at its
option, against the expenses of the sale, the cost of moving and storage and any
Rent due under this lease.

     (c)  If Tenant, or any person claiming through Tenant, shall continue to
occupy the Premises after the expiration or termination of this lease or any
renewal thereof, such occupancy shall be deemed to be under a month-to-month
tenancy under the same terms and conditions set forth in this lease, except that
the monthly installment of the Minimum  Annual Rent during such continued
occupancy shall be double the amount applicable to the last month of the Term.
Anything to the contrary notwithstanding, any holding over by Tenant without
Landlord's prior written consent shall constitute a default hereunder and shall
be subject to all the remedies available to Landlord.

22.  CURING TENANT'S DEFAULTS.  If Tenant shall be in default in the performance
     ------------------------                                                   
of any of its obligations hereunder, Landlord, without any obligation to do so,
in addition to any other rights it may have in law or equity, may elect to cure
such default on behalf of Tenant after written notice (except in the case of
emergency) to Tenant.  Tenant shall reimburse Landlord upon demand for any sums
paid or costs incurred by Landlord in curing such default, including interest
thereon from the respective dates of Landlord's incurring such costs, which sums
and costs together with interest shall be deemed additional rent.

23.  DEFAULTS; REMEDIES.
     ------------------ 

     (a)  DEFAULTS.  It shall be an event of default:

                                       12
<PAGE>
 
          (i)    If Tenant does not pay in full when due any and all Rent;

          (ii)   If Tenant fails to observe and perform or otherwise breaches
     any other provision of this lease;

          (iii)  If Tenant abandons the Premises, which shall be conclusively
     presumed if the Premises remain unoccupied for more than 10 consecutive
     days, or removes or attempts to remove Tenant's goods or property other
     than in the ordinary course of business; or

          (iv)   If Tenant becomes insolvent or bankrupt in any sense or makes a
     general assignment for the benefit of creditors or offers a settlement to
     creditors, or if a petition in bankruptcy or for reorganization or for an
     arrangement with creditors under any federal or state law is filed by or
     against Tenant, or a bill in equity or other proceeding for the appointment
     of a receiver for any of Tenant's assets is commenced, or if any of the
     real or personal property of Tenant shall be levied upon; provided,
     however, that any proceeding brought by anyone other than Landlord or
     Tenant under any bankruptcy, insolvency, receivership or similar law shall
     not constitute a default until such proceeding has continued unstayed for
     more than 60 consecutive days.

     (b)  REMEDIES.  Then, and in any such event, Landlord shall have the
following rights:

          (i)    To charge a late payment fee equal to the greater of $100 or 5%
     of any amount owed to Landlord pursuant to this lease which is not paid
     within 5 days after the due date.

          (ii)   To enter and repossess the Premises, by breaking open locked
     doors if necessary, and remove all persons and all or any property
     therefrom, by action at law or otherwise, without being liable for
     prosecution or damages therefor, and Landlord may, at Landlord's option,
     make alterations and repairs in order to relet the Premises and relet all
     or any part(s) of the Premises  for Tenant's account.  Tenant agrees to pay
     to Landlord on demand any deficiency that may arise by reason of such
     reletting.  In the event of releting without termination of this lease,
     Landlord may at any time thereafter elect to terminate this lease for such
     previous breach.

          (iii)  To accelerate the whole or any part of the Rent for the balance
     of the Term, and declare the same to be immediately due and payable.

          (iv)   To terminate this lease and the Term without any right on the
     part of Tenant to save the forfeiture by payment of any sum due or by other
     performance of any condition, term or covenant broken.

     (c)  GRACE PERIOD.  Notwithstanding anything hereinabove stated, neither
party will exercise any available right because of any default of the other,
except those remedies contained in subsection (b)(i) of this Section, unless
such party shall have first given 10 days written notice thereof to the
defaulting party, and the defaulting party shall have failed to cure the default
within such period; provided, however, that:

                                       13
<PAGE>
 
          (i)    No such notice shall be required if Tenant fails to comply with
     the provisions of Sections 10 or 20(a), in the case of emergency as set
     forth in Section 22 or in the event of any default enumerated in
     subsections (a)(iii) and (iv) of this Section.

          (ii)   Landlord shall not be required to give such 10 days notice more
     than 2 times during any 12 month period.

          (iii)  If the default consists of something other than the failure to
     pay money which cannot reasonably be cured within 10 days neither party
     will exercise any right if the defaulting party begins to cure the default
     within the 10 days and continues actively and diligently in good faith to
     completely cure said default.

          (iv)   Tenant agrees that any notice given by Landlord pursuant to
     this Section which is served in compliance with Section 27 shall be
     adequate notice for the purpose of Landlord's exercise of any available
     remedies.

     (d)  NON-WAIVER; NON-EXCLUSIVE.  No waiver by Landlord of any breach by
Tenant shall be a waiver of any subsequent breach, nor shall any forbearance by
Landlord to seek a remedy for any breach by Tenant be a waiver by Landlord of
any rights and remedies with respect to such or any subsequent breach.  Efforts
by Landlord to mitigate the damages caused by Tenant's default shall not
constitute a waiver of Landlord's right to recover damages hereunder.  No right
or remedy herein conferred upon or reserved to Landlord is intended to be
exclusive of any other right or remedy provided herein or by law, but each shall
be cumulative and in addition to every other right or remedy given herein or now
or hereafter existing at law or in equity.  No payment by Tenant or receipt or
acceptance by Landlord of a lesser amount than the total amount due Landlord
under this lease shall be deemed to be other than on account, nor shall any
endorsement or statement on any check or payment be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of Rent due, or Landlord's right to
pursue any other available remedy.

     (e)  COSTS AND ATTORNEYS' FEES.  If either party commences an action
against the other party arising out of or in connection with this lease, the
prevailing party shall be entitled to have and recover from the losing party
attorneys' fees, costs of suit, investigation expenses and discovery costs,
including costs of appeal.

24.  REPRESENTATIONS OF TENANT.  Tenant represents to Landlord and agrees that:
     -------------------------                                                 

     (a)  The word "Tenant" as used herein includes the Tenant named above as
well as its successors and assigns, each of which shall be under the same
obligations and liabilities and each of which shall have the same rights,
privileges and powers as it would have possessed had it originally signed this
lease as Tenant.  Each and every of the persons named above as Tenant shall be
bound jointly and severally by the terms, covenants and agreements contained
herein.  However, no such rights, privileges or powers shall inure to the
benefit of any assignee of Tenant immediate or remote, unless Tenant has
complied with the terms of Section 18 and the assignment to such assignee is
permitted or has been approved in writing by Landlord.  Any notice required or
permitted by the terms of this lease may be given by or to any one of the

                                       14
<PAGE>
 
persons named above as Tenant, and shall have the same force and effect as if
given by or to all thereof.

     (b)  If Tenant is a corporation, partnership or any other form of
business association or entity, Tenant is duly formed and in good standing, and
has full corporate or partnership power and authority, as the case may be, to
enter into this lease and has taken all corporate or partnership action, as the
case may be, necessary to carry out the transaction contemplated herein, so that
when executed, this lease constitutes a valid and binding obligation enforceable
in accordance with its terms.  Tenant shall provide Landlord with corporate
resolutions or other proof in a form acceptable to Landlord, authorizing the
execution of this lease at the time of such execution.

25.  LIABILITY OF LANDLORD.  The word "LANDLORD" as used herein includes the
     ---------------------                                                  
Landlord named above as well as its successors and assigns, each of which shall
have the same rights, remedies, powers, authorities and privileges as it would
have had it originally signed this lease as Landlord.  Any such person or
entity, whether or not named herein, shall have no liability hereunder after it
ceases to hold title to the Premises except for obligations already accrued
(and, as to any unapplied portion of Tenant's Security Deposit, Landlord shall
be relieved of all liability therefor upon transfer of such portion to its
successor in interest) and Tenant shall look solely to Landlord's successor in
interest for the performance of the covenants and obligations of the Landlord
hereunder which thereafter shall accrue.  Neither Landlord nor any principal of
Landlord nor any owner of the Property, whether disclosed or undisclosed, shall
have any personal liability with respect to any of the provisions of this lease
or the Premises, and if Landlord is in breach or default with respect to
Landlord's obligations under this lease or otherwise, Tenant shall look solely
to the equity of Landlord in the Property for the satisfaction of Tenant's
claims.  Notwithstanding the foregoing, no mortgagee or ground lessor succeeding
to the interest of Landlord hereunder (either in terms of ownership or
possessory rights) shall be (a) liable for any previous act or omission of a
prior landlord, (b) subject to any rental offsets or defenses against a prior
landlord or (c) bound by any amendment of this lease made without its written
consent, or by payment by Tenant of Minimum Annual Rent in advance in excess of
one monthly installment.

26.  INTERPRETATION; DEFINITIONS.
     --------------------------- 

     (a)  CAPTIONS.  The captions in this lease are for convenience only and are

land adjacent to the Property by Tenant by implication or otherwise except as
expressly set forth in the provisions of this lease.  This lease shall not be
modified in any manner except by an instrument in writing executed by the
parties.  The masculine (or neuter) pronoun and the singular number shall

having participated fully and equally in the negotiation and preparation of this
lease, this lease shall not be more strictly construed, nor any ambiguities in
this lease resolved, against either Landlord or Tenant.

     (c)  COVENANTS.  Each covenant, agreement, obligation, term, condition or
other provision herein contained shall be deemed and construed as a separate and
independent covenant of the party bound by, undertaking or making the same, not
dependent on any other provision of this lease unless otherwise expressly
provided.  All of the terms and conditions set forth in this lease shall apply
throughout the Term unless otherwise expressly set forth herein.

     (d)  INTEREST.  Wherever interest is required to be paid hereunder, such
interest shall be at the highest rate permitted under law but not in excess of
15% per annum.

     (e)  SEVERABILITY; GOVERNING LAW.  If any provisions of this lease shall be
declared unenforceable in any respect, such unenforceability shall not affect
any other provision of this lease, and each such provision shall be deemed to be
modified, if possible, in such a manner as to render it enforceable and to
preserve to the extent possible the intent of the parties as set forth herein.
This lease shall be construed and enforced in accordance with the laws of the
state in which the Property is located.

     (f)  "MORTGAGE" AND "MORTGAGEE." The word "MORTGAGE" as used herein
includes any lien or encumbrance on the Premises or the Property or on any part
of or interest in or appurtenance to any of the foregoing, including without
limitation any ground rent or ground lease if Landlord's interest is or becomes
a leasehold estate. The word "MORTGAGEE" as used herein includes the holder of
any mortgage, including any ground lessor if Landlord's interest is or becomes a
leasehold estate. Wherever any right is given to a mortgagee, that right may be
exercised on behalf of such mortgagee by any representative or servicing agent
of such mortgagee.

     (g)  "PERSON." The word "PERSON" is used herein to include a natural
person, a partnership, a corporation, an association and any other form of
business association or entity.

     (h)  PROPORTIONATE SHARE.  At any time or times, upon request of Landlord
or of any tenant of the Building, the method for allocating Tenant's
Proportionate Share of any Impositions, cost, charge, rent, expense or payment
then or thereafter payable shall be redetermined by an independent qualified
expert. The cost of such redetermination shall be borne by the tenants of the
Building in the same proportion as that determined by such expert for
reallocation of said relevant sum; except that if such redetermination is
requested by a tenant, the cost thereof shall be borne entirely by such tenant
if the proportionate share of said relevant sum allocable to such tenant as the
result of such redetermination shall not vary by at least 5% from the amount

for anyone claiming by, through or under Tenant and to confess judgment against
all such parties, and in favor of Landlord, in ejectment and for the recovery of
possession of the Premises, for which this lease or a true and correct copy
hereof shall be good and sufficient warrant.  AFTER THE ENTRY OF ANY SUCH
JUDGMENT A WRIT OF POSSESSION MAY BE ISSUED THEREON WITHOUT FURTHER NOTICE TO
TENANT AND WITHOUT A HEARING.  If for any reason after such action shall have
been commenced it shall be determined and possession of the Premises remain in
or be restored to Tenant, Landlord shall have the right for the same default and

right of possession as herein set forth, to again confess judgment as herein
provided, for which this lease or a true and correct copy hereof shall be good

WITHOUT A HEARING, AND, PURSUANT TO SUCH WRITS, LANDLORD MAY CAUSE THE SHERIFF
OF THE COUNTY IN WHICH ANY PROPERTY OF TENANT IS LOCATED TO SEIZE TENANT'S
PROPERTY BY LEVY OR ATTACHMENT.  IF THE JUDGMENT AGAINST TENANT REMAINS UNPAID
AFTER SUCH LEVY OR ATTACHMENT, LANDLORD CAN CAUSE SUCH PROPERTY TO BE SOLD BY
THE SHERIFF EXECUTING THE WRITS OR, IF SUCH PROPERTY CONSISTS OF A DEBT OWED TO
TENANT BY ANOTHER ENTITY, LANDLORD CAN CAUSE SUCH DEBT TO BE PAID DIRECTLY TO
LANDLORD IN AN AMOUNT UP TO BUT NOT TO EXCEED THE AMOUNT OF THE JUDGMENT
OBTAINED BY LANDLORD AGAINST TENANT, PLUS THE COSTS OF THE EXECUTION.  Such
authority shall not be exhausted by one exercise thereof, but judgment may be
confessed as aforesaid from time to time as often as any of said rental and
other sums shall fall due or be in arrears, and such powers may be exercised as
well after the expiration of the initial term of this lease and during any
extended or renewal term of this lease and after the expiration of any extended
or renewal term of this lease.

     (c)  The warrants to confess judgment set forth above shall continue in
full force and effect and be unaffected by amendments to this lease or other
agreements between Landlord and

                                      R-1

Tenant even if any such amendments or other agreements increase Tenant's
obligations or expand the size of the Premises. Tenant waives any procedural
errors in connection with the entry of any such judgment or in the issuance of
any one or more writs of possession or execution or garnishment thereon.

     (d)  TENANT KNOWINGLY AND EXPRESSLY WAIVES (I) ANY RIGHT, INCLUDING,
WITHOUT LIMITATION, UNDER ANY APPLICABLE STATUTE, WHICH TENANT MAY HAVE TO
RECEIVE A NOTICE TO QUIT PRIOR TO LANDLORD COMMENCING AN ACTION FOR REPOSSESSION
OF THE PREMISES AND (II) ANY RIGHT WHICH TENANT MAY HAVE TO NOTICE AND TO
HEARING PRIOR TO A LEVY UPON OR ATTACHMENT OF TENANT'S PROPERTY OR THEREAFTER.

improvement has been fully amortized pursuant to this provision, whichever shall

license fee; and (ii) inspect Licensee's facilities and procedures. The cost of
this audit shall be the responsibility of QI unless the audit shows an amount
owing to QI of at least five percent (5%) in addition to the amount paid by

audit. In no event shall audits be more frequently than semi-annually unless the

infringes any U.S. patent, copyright, or trade secret.  QI's obligation under
this section is conditioned on Licensee's agreement that if the QI Software, in

Software infringe a patent or copyright of a third party which claim is not
subject to indemnification by QI under the above paragraph.  Additionally,
Licensee will, at its expense defend QI against (a) any claim that arises out of
any alleged breach of warranty or representation given by Licensee in this
Agreement; (b) any breach of any obligation of Licensee under this Agreement.
Licensee will pay resulting costs and damages finally awarded by a court subject
to the paragraph below.

(d)  To qualify for such defense and payment, the indemnified party must: (i)
give the indemnifying party prompt written notice of any such claim; and (ii)
allow the indemnifying party to control the defense and cooperate with the
indemnifying party in the defense and settlement negotiations.

INDIRECT, ECONOMIC, PUNITIVE, SPECIAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF
ANY BREACH OR FAILURE UNDER THIS AGREEMENT, INCLUDING

                                                                     Page 2 of 6

their respective addresses set forth at the beginning of this Agreement or at

SILICON VALLEY BANK

     LOAN AND SECURITY AGREEMENT


BORROWER:  QUADRANT INTERNATIONAL, INC.
ADDRESS:   269 GREAT VALLEY PARKWAY
           MALVERN, PA 19365
DATE:      JULY 14, 1998


THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK, COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California 95054 and the borrower(s) named above
(jointly and severally, the "Borrower"), whose chief executive office is located
at the above address ("Borrower's Address").  The Schedule to this Agreement
(the "Schedule") shall for all purposes be deemed to be a part of this
Agreement, and the same is an integral part of this Agreement. (Definitions of
certain terms used in this Agreement are set forth in Section 8 below.)

1.   LOANS.

     1.1  LOANS.  Silicon will make loans to Borrower (the "Loans"), in amounts
determined by Silicon in its sole discretion, up to the amounts (the "Credit
Limit") shown on the Schedule, provided no Default or Event of Default has
occurred and is continuing, and subject to deduction of any Reserves for accrued
interest and such other Reserves as Silicon deems proper from time to time.

     1.2  INTEREST.  All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement. Interest shall be payable monthly, on the last
day of the month. Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon. Regardless of the amount of
Obligations that may be outstanding from time to time, Borrower shall pay
Silicon minimum monthly interest during the term of this Agreement in the amount
set forth on the Schedule (the "Minimum Monthly Interest").

     1.3  OVERADVANCES.  If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand.  Without limiting Borrower's obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rate equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

     1.4  FEES.  Borrower shall pay Silicon the fee(s) shown on the Schedule,
which are in addition to all interest and other sums payable to Silicon and are
not refundable.

     1.5  LETTERS OF CREDIT.  At the request of Borrower, Silicon may, in its
sole discretion, issue or arrange for the issuance of letters of credit for the
account of Borrower, in each case in form and substance satisfactory to Silicon
in its sole discretion (collectively, "Letters of Credit"). The aggregate face
amount of all outstanding Letters of Credit from time to time shall not exceed
the amount shown on the Schedule (the "Letter of Credit Sublimit"), and shall be
reserved against Loans which would otherwise be available hereunder. Borrower
shall pay all bank charges (including charges of Silicon) for the issuance of
Letters of Credit, together with such additional fee as Silicon's letter of
credit department shall charge in connection with the issuance of the Letters of
Credit. Any payment by Silicon under or in connection with a Letter of Credit
shall constitute a Loan hereunder on the date such payment is made. Each Letter
of Credit shall have an expiry date no later than thirty days prior to the
Maturity Date. Borrower hereby agrees to indemnify, save, and hold Silicon
harmless from any loss, cost, expense, or liability, including payments made by
Silicon, expenses, and reasonable attorneys' 
<PAGE>
 
fees incurred by Silicon arising out of or in connection with any Letters of
Credit. Borrower agrees to be bound by the regulations and interpretations of
the issuer of any Letters of Credit guarantied by Silicon and opened for
Borrower's account or by Silicon's interpretations of any Letter of Credit
issued by Silicon for Borrower's account, and Borrower understands and agrees
that Silicon shall not be liable for any error, negligence, or mistake, whether
of omission or commission, in following Borrower's instructions or those
contained in the Letters of Credit or any modifications, amendments, or
supplements thereto. Borrower understands that Letters of Credit may require
Silicon to indemnify the issuing bank for certain costs or liabilities arising
out of claims by Borrower against such issuing bank. Borrower hereby agrees to
indemnify and hold Silicon harmless with respect to any loss, cost, expense, or
liability incurred by Silicon under any Letter of Credit as a result of
Silicon's indemnification of any such issuing bank. The provisions of this Loan
Agreement, as it pertains to Letters of Credit, and any other present or future
documents or agreements between Borrower and Silicon relating to Letters of
Credit are cumulative.

2.   SECURITY INTEREST.

     2.1  SECURITY INTEREST.  To secure the payment and performance of all of

will at all times comply with all of the following covenants:

     3.1  CORPORATE EXISTENCE AND AUTHORITY.  Borrower, if a corporation, is and
will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Borrower is and will continue
to be qualified and licensed to do business in all jurisdictions in which any
failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (i) have been duly and validly authorized, (ii)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), and (iii) do not violate Borrower's articles or certificate
of incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property*.

     *EXCEPT FOR THE CREDIT FACILITY CURRENTLY IN PLACE WITH PROGRESS BANK WHICH
FACILITY WILL BE CONCURRENTLY PAID OFF WITH THE PROCEEDS OF LOANS UNDER THIS
AGREEMENT

     3.2  NAME; TRADE NAMES AND STYLES.  The name of Borrower set forth in the
heading to this Agreement is its correct name.  Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon 30 days' prior written notice before changing its
name or doing business under any other name.  Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

     3.3  PLACE OF BUSINESS; LOCATION OF COLLATERAL.  The address set forth in
the heading to this Agreement is Borrower's chief executive office. In addition,

     3.4  TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at all
times in the future be, the sole owner of all the Collateral, except for items
of Equipment which are leased by Borrower.  The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens.  Silicon now has,
and will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Silicon and the Collateral against all claims
of others.  None of the Collateral now is or will be affixed to any real
property in such a manner, or with such intent, as to become a fixture.
Borrower is not and will not become a lessee under any real property lease
pursuant to which the lessor may obtain any rights in any of the Collateral and
no such lease now prohibits, restrains, impairs or will prohibit, restrain or
impair Borrower's right to remove any Collateral from the leased premises.
Whenever any Collateral is located upon premises in which any third party has an
interest (whether as owner, mortgagee, beneficiary under a deed of trust, lien
or otherwise), Borrower shall, whenever *requested by Silicon, use its best
efforts to cause such third party to execute and deliver to Silicon, in form
*acceptable to Silicon, such waivers and subordinations as Silicon shall
specify, so as to ensure that Silicon's rights in the Collateral are, and will
continue to be, superior to the rights of any such third party.  Borrower will
keep in full force and effect, and will comply with all the terms of, any lease
of real property where any of the Collateral now or in the future may located.

     *REASONABLY

     3.5  MAINTENANCE OF COLLATERAL.  Borrower will maintain the Collateral in
good working condition, and Borrower will not use the Collateral for any
unlawful purpose. *Borrower will advise Silicon in writing of any material loss
or damage to the Collateral.

Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

     3.7  FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial statements
now or in the future delivered to Silicon have been, and will be, prepared in
conformity with generally accepted accounting principles and now and in the
future will* accurately reflect the financial condition of Borrower, at the
times and for the periods therein stated. Between the last date covered by any
such statement provided to Silicon and the date hereof, there has been no
material adverse change in the financial condition or business of Borrower.
Borrower is now and will continue to be solvent.

     *, IN ALL MATERIAL RESPECTS,

     3.8  TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS.  Borrower has timely
filed, and will timely file, all tax returns and reports required by foreign,
federal, state and local law, and Borrower has timely paid, and will timely pay,
all foreign, federal, state and local taxes, assessments, deposits and
contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. * or
adjustments proposed for any of Borrower's prior tax years which could result in
additional taxes becoming due and payable by Borrower. Borrower has paid, and
shall continue to pay all amounts necessary to fund all present and future
pension, profit sharing and deferred compensation plans in accordance with their
terms, and Borrower has not and will not withdraw from participation in, permit
partial or complete termination of, or permit the occurrence of any other event
with respect to, any such plan which could result in any liability of Borrower,
including any liability to the Pension Benefit Guaranty Corporation or its
successors or any other governmental agency. Borrower shall, at all times,
utilize the services of an outside payroll service providing for the automatic
deposit of all payroll taxes payable by Borrower.

     *NO NOTICE HAS BEEN RECEIVED BY BORROWER, NOR IS BORROWER AWARE, OF ANY
PENDING NOTICE

     3.9  COMPLIANCE WITH LAW.  Borrower has complied, and will comply, in all
material respects, with all provisions of all foreign, federal, state and local
laws and regulations relating to Borrower, including, but not limited to, those

licensing of Borrower's business, and all environmental matters.

     3.10  LITIGATION. Except as disclosed in the Schedule, there is no claim,
suit, litigation, proceeding or investigation pending or (to best of Borrower's
knowledge) threatened by or against or affecting Borrower in any court or before
any governmental agency (or any basis therefor known to Borrower) which may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Borrower, or in any material impairment
in the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted. Borrower will promptly inform Silicon in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of
$50,000 or more, or involving $100,000 or more in the aggregate.

     3.11  USE OF PROCEEDS.  All proceeds of all Loans shall be used solely for
lawful business purposes.  Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation U of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of
purchasing or carrying any "margin stock."

4.   RECEIVABLES.

     4.1   REPRESENTATIONS RELATING TO RECEIVABLES. Borrower represents and
warrants to Silicon as follows: Each Receivable with respect to which Loans are
requested by Borrower shall, on the date each Loan is requested and made, (i)
represent an undisputed bona fide existing unconditional obligation of the
Account Debtor created by the sale, delivery, and acceptance of goods or the
rendition of services in the ordinary course of Borrower's business, and (ii)
meet the Minimum Eligibility Requirements set forth in Section 8 below.

     4.2   REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE. Borrower
represents and warrants to Silicon as follows: All statements made and all
unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be,
and all signatories and endorsers have the capacity to contract.  All sales and
other transactions underlying or giving rise to each Receivable shall fully
comply with all applicable laws and governmental rules and regulations.  All
signatures and endorsements on all documents, instruments, and agreements
relating to all Receivables are and shall be genuine, and all such documents,
instruments and agreements are and shall be legally enforceable in accordance
with their terms.

     4.3   SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES. Borrower shall
deliver to Silicon transaction reports and loan requests, schedules and
assignments of all Receivables, and schedules of collections, all on Silicon's
standard forms; provided, however, that Borrower's failure to execute and
deliver the same shall not affect or limit Silicon's security interest and other
rights in all of Borrower's Receivables, nor shall Silicon's failure to advance
or lend against a specific Receivable affect or limit Silicon's security
interest and other rights therein. Loan requests received after 12:00 Noon will
not be considered by Silicon until the next Business Day. Together with each
such schedule and assignment, or later if requested by Silicon, Borrower shall
furnish Silicon with copies (or, at Silicon's request, originals) of all
contracts, orders, invoices, and other similar documents, and all original
shipping instructions, delivery receipts, bills of lading, and other evidence of
delivery, for any goods the sale or disposition of which gave rise to such
Receivables, and Borrower warrants the genuineness of all of the foregoing.
Borrower shall also furnish to Silicon an aged accounts receivable trial balance
in such form and at such intervals as Silicon shall request. In addition,
Borrower shall deliver to Silicon the originals* of all instruments, chattel
paper, security agreements, guarantees and other documents and property
evidencing or securing any Receivables, immediately upon receipt thereof and in
the same form as received, with all necessary endorsements, all of which shall
be with recourse. Borrower shall also provide Silicon with copies of all credit
memos within two days after the date issued.

     *(OR COPIES AS DETERMINED BY SILICON IN ITS OWN DISCRETION)

4.4  COLLECTION OF RECEIVABLES.  Borrower shall have the right to collect all
Receivables, unless and until a Default or an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Silicon, and Borrower shall immediately deliver all such payments and proceeds
to Silicon in their original form, duly endorsed in blank, to be applied to the
Obligations in such order as Silicon shall determine.  Silicon may, in its
discretion, require that all proceeds of Collateral be deposited by Borrower
into a lockbox account, or such other "blocked account" 

                                      -4-
<PAGE>
 
as Silicon may specify, pursuant to a blocked account agreement in such form as
Silicon may specify. Silicon or its designee may, at any time, notify Account
Debtors that the Receivables have been assigned to Silicon.

     4.5  REMITTANCE OF PROCEEDS. All proceeds arising from the disposition of
any Collateral shall be delivered, in kind, by Borrower to Silicon in the
original form in which received by Borrower not later than the following
Business Day after receipt by Borrower, to be applied to the Obligations in such
order as Silicon shall determine; provided that, if no Default or Event of
Default has occurred*, Borrower shall not be obligated to remit to Silicon the
proceeds of the sale of worn out or obsolete equipment disposed of by Borrower
in good faith in an arm's length transaction for an aggregate purchase price of
$25,000 or less (for all such transactions in any fiscal year). Borrower agrees
that it will not commingle proceeds of Collateral with any of Borrower's other
funds or property, but will hold such proceeds separate and apart from such
other funds and property and in an express trust for Silicon. Nothing in this
Section limits the restrictions on disposition of Collateral set forth elsewhere
in this Agreement.

     *AND IS CONTINUING

     4.6  DISPUTES. Borrower shall notify Silicon promptly of all disputes or 
claims relating to Receivables. Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in full,
or agree to do any of the foregoing, except that Borrower may do so, provided
that: (i) Borrower does so in good faith, in a commercially reasonable manner,
in the ordinary course of business, and in arm's length transactions, which are
reported to Silicon on the regular reports provided to Silicon; (ii) no Default
or Event of Default has occurred and is continuing; and (iii) taking into
account all such discounts settlements and forgiveness, the total outstanding
Loans will not exceed the Credit Limit. Silicon may, at any time after the
occurrence of an Event of Default,* settle or adjust disputes or claims directly
with Account Debtors for amounts and upon terms which Silicon considers
advisable in its reasonable credit judgment and, in all cases, Silicon shall
credit Borrower's Loan account with only the net amounts received by Silicon in
payment of any Receivables.

     *WHICH EVENT OF DEFAULT IS CONTINUING,

     4.7  RETURNS. Provided no Event of Default has occurred and is continuing,
if any Account Debtor returns any Inventory to Borrower in the ordinary course
of its business, Borrower shall promptly determine the reason for such return
and promptly issue a credit memorandum to the Account Debtor in the appropriate
amount (sending a copy to Silicon). In the event any attempted return occurs
after the occurrence of any Event of Default*, Borrower shall (i) hold the
returned Inventory in trust for Silicon, (ii) segregate all returned Inventory
from all of Borrower's other property, (iii) conspicuously label the returned
Inventory as Silicon's property, and (iv) immediately notify Silicon of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Silicon's request deliver such
returned Inventory to Silicon.

     *AND WHILE SUCH EVENT OF DEFAULT IS CONTINUING,

     4.8  VERIFICATION. Silicon may, from time to time, verify directly with the
respective Account Debtors the validity, amount and other matters relating to
the Receivables, by means of mail, telephone or otherwise, either in the name of
Borrower or Silicon or such other name as Silicon may choose.

     4.9  NO LIABILITY. Silicon shall not under any circumstances be responsible
or liable for any shortage or discrepancy in, damage to, or loss or destruction
of, any goods, the sale or other disposition of which gives rise to a
Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Silicon be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable. Nothing herein shall, however, relieve Silicon from liability for
its own gross negligence or willful misconduct.

5.   ADDITIONAL DUTIES OF THE BORROWER.

     5.1  FINANCIAL AND OTHER COVENANTS. Borrower shall at all times comply with
the financial and other covenants set forth in the Schedule.

     5.2  INSURANCE.  Borrower shall, at all times insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Silicon, in such form and amounts as Silicon
may reasonably require, and Borrower shall provide evidence of such insurance to
Silicon, so that Silicon is satisfied that such insurance 

                                      -5-
<PAGE>
 
is, at all times, in full force and effect. All such insurance policies shall
name Silicon as an additional loss payee, and shall contain a lenders loss payee
endorsement in form reasonably acceptable to Silicon. Upon receipt of the
proceeds of any such insurance, Silicon shall apply such proceeds in reduction
of the Obligations as Silicon shall determine in its sole discretion, except
that, provided no Default or Event of Default has occurred and is continuing,
Silicon shall release to Borrower insurance proceeds with respect to Equipment
totaling less than $100,000, which shall be utilized by Borrower for the
replacement of the Equipment with respect to which the insurance proceeds were
paid. Silicon may require reasonable assurance that the insurance proceeds so
released will be so used. If Borrower fails to provide or pay for any insurance,
Silicon may, but is not obligated to, obtain the same at Borrower's expense.
Borrower shall promptly deliver to Silicon copies of all reports made to
insurance companies.

     5.3  REPORTS.  Borrower, at its expense, shall provide Silicon with the

other financial documentation), as Silicon shall from time to time reasonably
specify.

     5.4  ACCESS TO COLLATERAL, BOOKS AND RECORDS.  At reasonable times, and on
one Business Day's notice, Silicon, or its agents, shall have the right to
inspect the Collateral and the right to audit and copy Borrower's books and
records. Silicon shall take reasonable steps to keep confidential all
information obtained in any such inspection or audit, but Silicon shall have the
right to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $500 per person per day (or such higher amount as shall represent
Silicon's then current standard charge for the same), plus reasonable out of
pocket expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, without first obtaining Silicon's
written consent, which may be conditioned upon such accounting firm, service
bureau or other third party agreeing to give Silicon the same rights with
respect to access to books and records and related rights as Silicon has under
this Loan Agreement. Borrower waives the benefit of any accountant-client
privilege or other evidentiary privilege precluding or limiting the disclosure,
divulgence or delivery of any of its books and records (except that Borrower
does not waive any attorney-client privilege).

     5.5  NEGATIVE COVENANTS. Except as may be permitted in the Schedule,
Borrower shall not, without Silicon's prior written consent, do any of the
following: (i) merge or consolidate with another corporation or entity; (ii)
acquire any assets, except in the ordinary course of business; (iii) enter into
any other transaction outside the ordinary course of business; (iv) sell or
transfer any Collateral, except for the sale of finished Inventory in the

adverse effect on Borrower or on the prospect of repayment of the Obligations;
(ix) guarantee or otherwise become liable with respect to the obligations of
another party or entity; (x) *pay or declare any dividends on Borrower's stock
(except for dividends payable solely in stock of Borrower); (xi) *redeem,

stock; (xii) make any change in Borrower's capital structure which would have a
material adverse effect on Borrower or on the prospect of repayment of the
Obligations; or (xiii) pay total compensation, including salaries, fees,
bonuses, commissions, and all other payments, whether directly or indirectly, in
money or otherwise, to Borrower's executives, officers and directors (or any
relative thereof) in an amount in excess of the amount set forth on the
Schedule; or (xiv) dissolve or elect to dissolve. Transactions permitted by the
foregoing provisions of this Section are only permitted if no Default or Event
of Default would occur as a result of such transaction.

     *EXCEPT AS REQUIRED BY BORROWER'S ARTICLES OF INCORPORATION IN EFFECT ON
THE DATE HEREOF, AS AMENDED FROM TIME TO TIME (CERTIFIED COPIES OF ALL
AMENDMENTS TO THE ARTICLES OF INCORPORATION ADOPTED BY THE BORROWER AFTER THE
DATE HEREOF SHALL BE PROVIDED TO SILICON PROMPTLY, BUT IN NO EVENT WITHIN 15
DAYS AFTER SUCH AMENDMENT HAS BEEN FILED WITH THE SECRETARY OF THE
COMMONWEALTH),

<PAGE>
 
     5.6  LITIGATION COOPERATION.  Should any third-party suit or proceeding be
instituted by or against Silicon with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to Silicon, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Silicon may deem them reasonably necessary in order
to prosecute or defend any such suit or proceeding.

     5.7  FURTHER ASSURANCES.  Borrower agrees, at its expense, on request by
Silicon, to execute all documents and take all actions, as Silicon, may deem
reasonably necessary or useful in order to perfect and maintain Silicon's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

6.   TERM.

     6.1  MATURITY DATE. This Agreement shall continue in effect until the
maturity date set forth on the Schedule (the "Maturity Date"); provided that the
Maturity Date shall automatically be extended, and this Agreement shall
automatically and continuously renew, for successive additional terms of one
year each, unless one party gives written notice to the other, not less than
sixty days prior to the next Maturity Date, that such party elects to terminate
this Agreement effective on the next Maturity Date.

     6.2  EARLY TERMINATION.  This Agreement may be terminated prior to the
Maturity Date as follows: (i) by Borrower, effective three Business Days after
written notice of termination is given to Silicon; or (ii) by Silicon at any
time after the occurrence of an Event of Default, without notice, effective
immediately. If this Agreement is terminated by Borrower or by Silicon under
this Section 6.2, Borrower shall pay to Silicon a termination fee in an amount
equal to* of the Maximum Credit Limit**. The termination fee shall be due and
payable on the effective date of termination and thereafter shall bear interest
at a rate equal to the highest rate applicable to any of the Obligations.

     *ONE-HALF OF ONE PERCENT (0.50%)

     **PROVIDED, HOWEVER, NO SUCH TERMINATION FEE SHALL BE CHARGED IF THE CREDIT
FACILITY HEREUNDER IS REPLACED WITH A NEW FACILITY FROM ANOTHER LENDING DIVISION
OF SILICON VALLEY BANK

     6.3  PAYMENT OF OBLIGATIONS.  On the Maturity Date or on any earlier
effective date of termination, Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or
not all or any part of such Obligations are otherwise then due and payable.
Without limiting the generality of the foregoing, if on the Maturity Date, or on
any earlier effective date of termination, there are any outstanding Letters of
Credit issued by Silicon or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Silicon's then
standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Silicon, Silicon may, in its sole discretion, refuse to make any further Loans
after termination. No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Silicon's security interests.

any instrument evidencing or relating to any Obligation; (c) Take possession of
any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Silicon without judicial process to enter onto any of
Borrower's premises without interference to search for, take possession of,
keep, store, or remove any of the Collateral, and remain on the premises or
cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Silicon deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other
agreement; provided, however, that should Silicon seek to take possession of any
of the Collateral by Court process, Borrower hereby irrevocably waives: (i) any
bond and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession; (ii) any demand for
possession prior to the commencement of any suit or action to recover possession
thereof; and (iii) any requirement that Silicon retain possession of, and not
dispose of, any such Collateral until after trial or final judgment; (d) Require
Borrower to assemble any or all of the 

                                      -8-
<PAGE>
 
Collateral and make it available to Silicon at places designated by Silicon
which are reasonably convenient to Silicon and Borrower, and to remove the
Collateral to such locations as Silicon may deem advisable; (e) Complete the
processing, manufacturing or repair of any Collateral prior to a disposition
thereof and, for such purpose and for the purpose of removal, Silicon shall have
the right to use Borrower's premises, vehicles, hoists, lifts, cranes, equipment
and all other property without charge; (f) Sell, lease or otherwise dispose of
any of the Collateral, in its condition at the time Silicon obtains possession
of it or after further manufacturing, processing or repair, at one or more
public and/or private sales, in lots or in bulk, for cash, exchange or other
property, or on credit, and to adjourn any such sale from time to time without
notice other than oral announcement at the time scheduled for sale. Silicon
shall have the right to conduct such disposition on Borrower's premises without
charge, for such time or times as Silicon deems reasonable, or on Silicon's
premises, or elsewhere and the Collateral need not be located at the place of
disposition. Silicon may directly or through any affiliated company purchase or
lease any Collateral at any such public disposition, and if permissible under
applicable law, at any private disposition. Any sale or other disposition of
Collateral shall not relieve Borrower of any liability Borrower may have if any
Collateral is defective as to title or physical condition or otherwise at the
time of sale; (g) Demand payment of, and collect any Receivables and General
Intangibles comprising Collateral and, in connection therewith, Borrower
irrevocably authorizes Silicon to endorse or sign Borrower's name on all
collections, receipts, instruments and other documents, to take possession of
and open mail addressed to Borrower and remove therefrom payments made with
respect to any item of the Collateral or proceeds thereof, and, in Silicon's
sole discretion, to grant extensions of time to pay, compromise claims and
settle Receivables and the like for less than face value; (h) Offset against any
sums in any of Borrower's general, special or other Deposit Accounts with
Silicon; and (i) Demand and receive possession of any of Borrower's federal and
state income tax returns and the books and records utilized in the preparation
thereof or referring thereto. All reasonable attorneys' fees, expenses, costs,
liabilities and obligations incurred by Silicon with respect to the foregoing
shall be added to and become part of the Obligations, shall be due on demand,
and shall bear interest at a rate equal to the highest interest rate applicable
to any of the Obligations. Without limiting any of Silicon's rights and
remedies, from and after the occurrence of any Event of Default, the interest
rate applicable to the Obligations shall be increased by an additional four
percent per annum.

     7.3    STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and
Silicon agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to
Borrower at least seven days prior to the sale, and, in the case of a public
sale, notice of the sale is published at least seven days before the sale in a
newspaper of general circulation in the county where the sale is to be
conducted; (ii) Notice of the sale describes the collateral in general, non-
specific terms; (iii) The sale is conducted at a place designated by Silicon,
with or without the Collateral being present; (iv) The sale commences at any
time between 8:00 a.m. and 6:00 p.m; (v) Payment of the purchase price in cash
or by cashier's check or wire transfer is required; (vi) With respect to any
sale of any of the Collateral, Silicon may (but is not obligated to) direct any
prospective purchaser to ascertain directly from Borrower any and all
information concerning the same. Silicon shall be free to employ other methods
of noticing and selling the Collateral, in its discretion, if they are
commercially reasonable.

     7.4  POWER OF ATTORNEY. *without limiting Silicon's other rights and
remedies, Borrower grants to Silicon an irrevocable power of attorney coupled
with an interest, authorizing and permitting Silicon (acting through any of its
employees, attorneys or agents) at any time, at its option, but without
obligation, with or without notice to Borrower, and at Borrower's expense, to do
any or all of the following, in Borrower's name or otherwise, but Silicon agrees
to exercise the following powers in a commercially reasonable manner: (a)
Execute on behalf of Borrower any documents that Silicon may, in its sole
discretion, deem advisable in order to perfect and maintain Silicon's security
interest in the Collateral, or in order to exercise a right of Borrower or
Silicon, or in order to fully consummate all the transactions contemplated under
this Agreement, and all other present and future agreements; (b) Execute on
behalf of Borrower any document exercising, transferring or assigning any option
to purchase, sell or otherwise dispose of or to lease (as lessor or lessee) any
real or personal property which is part of Silicon's Collateral or in which
Silicon has an interest; (c) Execute on behalf of Borrower, any invoices
relating to any Receivable, any draft against any Account Debtor 

                                      -9-
<PAGE>
 
and any notice to any Account Debtor, any proof of claim in bankruptcy, any
Notice of Lien, claim of mechanic's, materialman's or other lien, or assignment
or satisfaction of mechanic's, materialman's or other lien; (d) Take control in
any manner of any cash or non-cash items of payment or proceeds of Collateral;
endorse the name of Borrower upon any instruments, or documents, evidence of
payment or Collateral that may come into Silicon's possession; (e) Endorse all
checks and other forms of remittances received by Silicon; (f) Pay, contest or
settle any lien, charge, encumbrance, security interest and adverse claim in or
to any of the Collateral, or any judgment based thereon, or otherwise take any
action to terminate or discharge the same; (g) Grant extensions of time to pay,
compromise claims and settle Receivables and General Intangibles for less than
face value and execute all releases and other documents in connection therewith;
(h) Pay any sums required on account of Borrower's taxes or to secure the
release of any liens therefor, or both; (i) Settle and adjust, and give releases
of, any insurance claim that relates to any of the Collateral and obtain payment
therefor; (j) Instruct any third party having custody or control of any books or
records belonging to, or relating to, Borrower to give Silicon the same rights
of access and other rights with respect thereto as Silicon has, under this
Agreement; and (k) Take any action or pay any sum required of Borrower pursuant
to this Agreement and any other present or future agreements. Any and all
reasonable sums paid and any and all reasonable costs, expenses, liabilities,
obligations and attorneys' fees incurred by Silicon with respect to the
foregoing shall be added to and become part of the Obligations, shall be payable
on demand, and shall bear interest at a rate equal to the highest interest rate
applicable to any of the Obligations. In no event shall Silicon's rights under
the foregoing power of attorney or any of Silicon's other rights under this
Agreement be deemed to indicate that Silicon is in control of the business,
management or properties of Borrower.

     *PROVIDED AN EVENT OF DEFAULT HAS OCCURRED AND IS CONTINUING,

     7.5  APPLICATION OF PROCEEDS. All proceeds realized as the result of any
sale of the Collateral shall be applied by Silicon first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon in the exercise of its rights under this Agreement, second to the
interest due upon any of the Obligations, and third to the principal of the
Obligations, in such order as Silicon shall determine in its sole discretion.
Any surplus shall be paid to Borrower or other persons legally entitled thereto;
Borrower shall remain liable to Silicon for any deficiency. If, Silicon, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

     7.6  REMEDIES CUMULATIVE. In addition to the rights and remedies set forth
in this Agreement, Silicon shall have all the other rights and remedies accorded
a secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Silicon and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver thereof, but all rights and remedies
shall continue in full force and effect until all of the Obligations have been
fully paid and performed.

writing, or backed by a letter of credit satisfactory to Silicon, or FCIA
insured satisfactory to Silicon), (ix) the Receivable must not be owing from an
Account Debtor to whom Borrower is or may be liable for goods purchased from
such Account Debtor or otherwise.  Receivables owing from one Account Debtor

Receivables owing from an Account Debtor are outstanding more than 90 days from
their invoice date (without regard to unapplied credits) or are otherwise not
eligible Receivables, then all Receivables owing from that Account Debtor will
be deemed ineligible for borrowing.  Silicon may, from time to time, in its
discretion, revise the Minimum Eligibility Requirements, upon written notice to
the Borrower.

of the foregoing, any such funds received after 12:00 Noon* on any day shall be
deemed received on the next Business Day.  Silicon shall not, however, be
required to credit Borrower's account for the amount of any item of payment
which is unsatisfactory to Silicon in its sole discretion, and Silicon may
charge Borrower's loan account for the amount of any item of payment which is
returned to Silicon unpaid.

     *PACIFIC STANDARD TIME

     9.2  APPLICATION OF PAYMENTS.  All payments with respect to the Obligations
may be applied, and in Silicon's sole discretion reversed and re-applied, to the
Obligations, in such order and manner as Silicon shall determine in its sole
discretion.

     9.3  CHARGES TO ACCOUNTS.  Silicon may, in its discretion, require that
Borrower pay monetary Obligations in cash to Silicon, or charge them to
Borrower's Loan account, in which event they will bear interest at the same rate
applicable to the Loans.  Silicon may also, in its discretion, charge any
monetary Obligations to Borrower's Deposit Accounts maintained with Silicon.

     9.4  MONTHLY ACCOUNTINGS.  Silicon shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement.  Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of

notifies Silicon in writing to the contrary within thirty days after each
account is rendered, describing the nature of any alleged errors or admissions.

     9.5  NOTICES.  All notices to be given under this Agreement shall be in
writing and shall be given either personally or by reputable private delivery

all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement. There are
                                                                      ---------

- -------------------------------------------------------------------------------
are not set forth in this Agreement or in other written agreements signed by the

     9.8   WAIVERS.  The failure of Silicon at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Silicon shall not waive
or diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Silicon shall be deemed to have been
waived by any act or knowledge of Silicon or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Silicon and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time held
by Silicon on which Borrower is or may in any way be liable, and notice of any

its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Silicon shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Borrower or any other party through the ordinary negligence of Silicon, or
any of its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Silicon, but nothing herein shall relieve
Silicon from liability for its own gross negligence or willful misconduct.

     9.10  AMENDMENT.  The terms and provisions of this Agreement may not be
waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Silicon.

     9.11  TIME OF ESSENCE.  Time is of the essence in the performance by
Borrower of each and every obligation under this Agreement.

     9.12  ATTORNEYS FEES AND COSTS.  Borrower shall reimburse Silicon for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Silicon incurs in order to do the following: prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement or Borrower; enforce, or seek to enforce, any of
its rights; prosecute actions against, or defend actions by, Account Debtors;
commence, intervene in, or defend any action or proceeding; initiate any
complaint to be relieved of the automatic stay in bankruptcy; file or prosecute
any probate claim, bankruptcy claim, third-party claim, or other claim; examine,
audit, copy, and inspect any of the Collateral or any of Borrower's books and
records; protect, obtain possession of, lease, dispose of, or otherwise enforce

                                         -----------------------------------
hereunder to reimburse Silicon for attorneys fees, Borrower may, for
- --------------------------------------------------------------------
convenience, issue checks directly to Silicon's attorneys, Levy, Small & Lallas,
- --------------------------------------------------------------------------------
but Borrower acknowledges and agrees that Levy, Small & Lallas is representing
- ------------------------------------------------------------------------------
only Silicon and not Borrower in connection with this Agreement.  If either
- ---------------------------------------------------------------            
Silicon or Borrower files any lawsuit against the other predicated on a breach
of this Agreement, the prevailing party in such action shall be entitled to
recover its reasonable costs and attorneys' fees, including (but not limited to)
reasonable attorneys' fees and costs incurred in the enforcement of, execution
upon or defense of any order, decree, award or judgment.  All attorneys' fees
and costs to which Silicon may be entitled pursuant to this Paragraph shall
immediately become part of Borrower's Obligations, shall be due on demand, and
shall bear interest at a rate equal to the highest interest rate applicable to
any of the Obligations.

     9.13  BENEFIT OF AGREEMENT.  The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Silicon; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Silicon, and any prohibited
assignment shall be void. 

                                      -14-
<PAGE>
 
No consent by Silicon to any assignment shall release Borrower from its
liability for the Obligations.

     9.14  JOINT AND SEVERAL LIABILITY.  If Borrower consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

     9.15  LIMITATION OF ACTIONS.  Any claim or cause of action by Borrower
against Silicon, its directors, officers, employees, agents, accountants or
attorneys, based upon, arising from, or relating to this Loan Agreement, or any
other present or future document or agreement, or any other transaction
contemplated hereby or thereby or relating hereto or thereto, or any other
matter, cause or thing whatsoever, occurred, done, omitted or suffered to be
done by Silicon, its directors, officers, employees, agents, accountants or
attorneys, shall be barred unless asserted by Borrower by the commencement of an
action or proceeding in a court of competent jurisdiction by the filing of a
complaint within one year after the first act, occurrence or omission upon which
such claim or cause of action, or any part thereof, is based, and the service of
a summons and complaint on an officer of Silicon, or on any other person
authorized to accept service on behalf of Silicon, within thirty (30) days
thereafter. Borrower agrees that such one-year period is a reasonable and
sufficient time for Borrower to investigate and act upon any such claim or cause
of action. The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Silicon in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

     9.16  PARAGRAPH HEADINGS; CONSTRUCTION.  Paragraph headings are only used
in this Agreement for convenience. Borrower and Silicon acknowledge that the
headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe, limit,
define or interpret any term or provision of this Agreement. The term
"including", whenever used in this Agreement, shall mean "including (but not
limited to)". This Agreement has been fully reviewed and negotiated between the
parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Silicon or Borrower under any rule
of construction or otherwise.

     9.17  GOVERNING LAW; JURISDICTION; VENUE.  This Agreement and all acts and
transactions hereunder and all rights and obligations of Silicon and Borrower
shall be governed by the laws of the State of California.  As a material part of
the consideration to Silicon to enter into this Agreement, Borrower (i) agrees
that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Silicon's option, be litigated in courts located within
California, and that the exclusive venue therefor shall be Santa Clara County;
(ii) consents to the jurisdiction and venue of any such court and consents to
service of process in any such action or proceeding by personal delivery or any
other method permitted by law; and (iii) waives any and all rights Borrower may
have to object to the jurisdiction of any such court, or to transfer or change
the venue of any such action or proceeding.

OMISSIONS OF SILICON OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES,
AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH SILICON OR BORROWER, IN

      number 7131600 at Commerzbank Wiesbaden AG (bank code number 510 400 38).

V.    Changes in lease

      The basic lease agreed to in IV. shall be raised as follows:

      starting on January 1, 1997  from DM 1,526.00  to DM 1,744.00

      If the index of a four-person household of blue-collar and white-collar
      workers with a mid-level income (basis year 1985 = 100) should change by
      more than 10 points upward or downward with respect to the status of
      January 1, 1997, and/or with respect to the state of the applicable most-
      recent reevaluation of the lease rate set by the Federal Bureau of
      Statistics in Wiesbaden, then either party to this contract can demand an
      adjustment in the same relationship, specifically, from the start of the
      calendar year that follows the month the application is submitted.


                                                                              /3
- ---------------------
/4/ Translator's Note: AVG refers to the "The General Contractual Agreements for
    Commercial Leases."
<PAGE>
 
                                     - 3 -

      If, on the basis of a preexisting value-assurement clause, an adjustment
      of the lease rate has taken place, the rule for further changes in the
      price index for lifestyle by more than 10 points, respectively, is again
      applicable, always with reference to the index which had application in
      the month of the last lease adjustment.

      The parties to this contract are aware that this clause requires approval
      from the LZB/5/ responsible.  The tenant authorizes the landlord as of now
      to obtain this approval.

      If, on the basis of an update by the Federal Bureau of Statistics, the
      basis year for the lifestyle cost index is introduced or if the
      aforementioned lifestyle cost index is replaced by another comparable
      index, then the respective index applies for the lease adjustment on the
      basis of the new basis year and/or of the new index.  For the time up to
      the next adjustment deadline, the old index will continue to apply--if
      necessary after the resetting of the basis.

VI.   Lease security deposit

      The tenant will provide a lease security deposit in the amount of DM
      10,000.00 (in words: ten thousand German marks) with a bank acting as
      guarantor.

VII.  Other agreements

      a) When splitting any elevator-related operational expenses, the tenants
      on the ground floor will be excluded.

      b) The landlord is not obligated nor authorized to insure mirrors, glass
      panes, and awnings at the expense of the tenants.

VIII. The General Contractual Agreements for Commercial Leases (AVG) and the
      Building Code are integral components of this commercial lease.  The
      tenant confirms that he or she has received these.

2.    The total monthly payments as of October 1, 1996, tentatively, at the

      1.  the basic monthly rent will amount currently to      DM 3,416.00

      2.  additional monthly operational cost prepayments
          ((S) 6 AVG) currently                                DM 700.00

      3.  additional monthly elevator-related prepayment
          ((S) 7 AVG) currently                                DM 230.00
                                                               ---------

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

1.    Rental agreement no. 130.0002 from August 10, 1998, regarding the second
      floor will end on March 31, 1999.

2.    On April 1, 1999, the tenant will also take over the second floor with an
      office area of 135 square meters in addition to the area already in use on
      the 5th floor with 135 square meters and the 6th floor with 105 square
      meters.

3.    The total monthly payments will be calculated as of April 1, 1999, as
      follows:

 
           basic rent currently                         DM 5,740.00
           additional operational cost prepayments      DM 1,150.00
           additional elevator-related prepayments      DM   360.00
                                                        -----------
                                                        DM 7,250.00
           additional applicable value-added tax,
           currently 16%                                DM 1,160.00
                                                        -----------
           total monthly payment currently              DM 8,410.00
                                                        ===========

4.    In amendment to point V. (Changes in rent) of the rental contract, the
      price index for the lifestyle of all private households for Germany (basis
      year 1991 = 100) will serve as basis.

      The rent adjustments in accordance with the lifestyle cost index will
      begin with the status of January 1996.  Upon the first increase of the
      rental rate, a basic rent of DM 14.00 per square meter will be the
      starting point.  For successive rent rates, the basic rent per square
      meter resulting from the preceding rent rate increase will be the starting
      point.

5.    In amendment to point III (Rental duration), the rental relationship will
      be extended by 10 years.  Thus, the rental period will end on March 31,
      2009.
<PAGE>
 
      If the rental relationship is not otherwise terminated at least 12 months
      before its expiration, then it will be extended each time by 12 months.

6.    The rental security deposit for the total area of 379 square meters will
      be set at DM 20,000.00 and can be provided via exchange of the already
      existing guarantor client over DM 12,000.00.

7.    The estimated price for building administration in accordance with (S) 6
      AVG is agreed to at 3 % of the basic rent.

8.    All other conditions of the rental contract as well as amendments will
      retain their validity.

General Contractual Agreements Commercial Rental Agreement (AVG)

(S) 1a  Transfer of prepared rental rooms

1.    The landlord will transfer to the tenant the rental rooms at the start of
      the rental period.

2.    The landlord will not guarantee, however, that the rental rooms will have
      been cleared by third parties by the start of the rental period, unless
      the damages incurred by the tenant because of this touch on any
      intentional or grossly negligent violation of this contract on the part of
      the landlord. The right to withdraw from the contract on the part of the
      tenant will remain untouched by this.

3.    The state of the rental rooms at the point in time of the transfer will be
      set forth, if necessary, in a damage report.  Deficiencies in the rental
      space can be made valid by the tenant only if they are identified at the
      time of the rental rooms' transfer and their confirmation is confirmed in
      writing. Insubstantial deficiencies and any residual work do not authorize
      the tenant to refuse accepting the transfer of the rental rooms.

4.    The landlord will turn over to the tenant the required keys.  The
      acquisition of additional keys by the tenant requires the approval of the
      landlord.

      If a key is lost, the tenant has the right to demand a replacement key at
      the cost of the landlord and to have the required number of keys made.  If
      the lock needs to be replaced entirely or in part because of security
      reasons, the landlord bears the costs resulting therefrom.

(S) 1b  Transfer of not-yet prepared rental rooms

1.    If the start of the rental period cannot be determined in a binding
      fashion at the time of concluding the contract, then it will begin on the
      date of the deadline for completion of any building-related work regarding
      which the landlord will provide information, on which date the rental
      rooms have been prepared in accordance with the building and equipment
      description and can be transferred. From this point in time on, the rent
      is to be paid regardless of any not-yet finished division or other work,
      if necessary, which the tenant may undertake for his or her rental rooms,
      and/or services that the landlord can provide only after the tenant has
      finished renovations.

2.    If upon transfer of the rental rooms there are parts of the total object
      that are not yet ready, the tenant may not derive any rights from this; he
      or she is in particular not authorized to refuse to accept transfer
      insofar as this does not substantially impinge upon the contract-related
      use of the rental rooms.

3.    The state of the rental rooms at the point in time that they are
      transferred will be set out in the damage report.  Deficiencies in the
      rental space can be made valid by the tenant only if they were identified
      at the time the rental rooms were transferred and their correction was
      agreed to in writing.  Insubstantial deficiencies
<PAGE>
 
                                     - 2 -

      and residual work do not authorize the tenant to refuse to accept transfer
      of the rental rooms.

4.    (S) 1a No. 4 applies as applicable.


(S) 2  Use of the rental rooms and of community property

1.    The rental rooms have been rented only for the use as agreed to.

2.    The landlord does not guarantee that the rental rooms are suitable for
      that use nor that they conform to technical and official specifications.
      If there are no correctable, legal, or actual restrictions that are
      founded in the person of the tenant with respect to the agreed use, then
      the tenant has the right to withdraw from the contract. Official approvals
      are to be obtained by the tenant. The costs of the use inspection, the
      official approvals, and the fulfillment of production including the
      acquisition or disposal of parking spaces will be borne by the tenant.

3.    The landlord guarantees no competitive or assortment protection. He or she
      is in particular not liable for the fact that whole or partial overlap
      with competitors exists with other tenants now or in the future.

4.    Operational obligations are incumbent on the tenant in restaurants and
      pubs during legal business hours insofar as deviating business hours are
      not otherwise determined by the landlord.

5.    Store facilities, ware presentation, and display window decorations must
      be done in a fashion that is suitable for the area of business and the
      location of the contractual object. The landlord is authorized to
      determine the length of time that lighting may be on for display windows.

      The setup and operation of game machines requires the previously written
      approval of the landlord.

6.    Sellouts and clearance sales require the previous written approval of the
      landlord.

7.    The delivery of wares for the rental object must take place with respect
      to time of day and to delivery method such that no impingement on other
      tenants is possible.

      No objects and products may be stored or sold outside of the leased areas.

8.    The tenant is liable for any legally permissible level of construction-
      related burden on floor coverings being exceeded.

9.    The elevators will be kept operational during those periods of
<PAGE>
 
                                     - 3 -

      time set by the landlord; however, the tenant does not have a right to
      uninterrupted service.

10.   Insofar as parking places are provided for free, the landlord will retain
      the right to enforce another rule (e.g. parking fees, gates) upon which
      changes the tenant may not base any claims.

      The tenant is obligated to be connected to a parking fee reimbursement, if
      necessary.

      It is open to the landlord--and with his or her approval to third parties
      as well (e.g. an advertising company)--to claim any areas not belonging to
      the rented area (e.g. parking areas, passages, and/or other attached
      areas) for special events or other purposes that may appear to the
      landlord to be appropriate in the interest of the contractual object.

11.   The cleaning of the traffic areas (e.g. footpaths, stairwells, basement
      rooms, etc.) and of the community property (e.g. elevators) is incumbent
      on the tenant. On this point, he or she must adhere to the regulations of
      the local police.

      The landlord is authorized to have such work performed for the tenant and
      to bill the tenant for the costs arising from this.

12.   The landlord is authorized to control the operation of the community
      property in a use ordinance. He or she will endeavor to keep community
      property in working order for the time being and to correct any
      disruptions immediately. If a piece of community property cannot be used
      temporarily, the tenants will have a right to reimbursement for damages
      only in the case of intentional or grossly negligent action on the part of
      the landlord.

      With respect to the interests and requirements of the tenant, the landlord
      may remove, change, or acquire new community property; this also applies
      to any buildings that may be added on to the broad-band cable network of
      the German Federal Post Office. The landlord can bill the costs for this
      to the tenants.

13.   The use of traffic areas and community property can be reregulated by the
      landlord.

(S) 3  Sublets, building-related changes by the tenant, advertising

1.    The tenant is authorized only with previous written permission from the
      landlord to withdraw from rights under the rental agreement or to sublet
      the rental rooms wholly or partially to third parties.  This also applies
      to a change in ownership due to change in the legal form of the company.
<PAGE>
 
                                     - 4 -

      The landlord can make his or her approval for any sublet dependent on an
      appropriate increase in the basic rent.

      If the landlord refuses to approve the sublet, the tenant has no right to
      terminate the contract.

      In the event that subletting occurs, the tenant will immediately defer all
      rights against the third party to the landlord.

2.    Building-related changes to the rental rooms by the tenant require the
      previous written approval of the landlord.  Official permits will be
      obtained by the tenant.

      All production and cost requirements--stemming from the construction-
      related costs predicted by and/or taken by the tenant or from the use of
      the rental rooms--from third parties (in particular local authorities,
      suppliers, etc.) must be followed through on by the tenant and/or must be
      billed to him or her.  The tenant will leave open to the landlord the
      fulfillment of any such production and cost requirements, including
      acquisition or disposal of parking places.
 
3.    Roof and facade areas of the building, as well as wall areas on the inside
      of the building outside of the rental rooms, have not been rented out.
      They may be used by the tenant, only after getting prior written approval
      from the landlord, for advertising purposes or for attaching directional
      signs.

      The tenant may attach company signs at his or her own expense only to
      areas previously approved by the landlord. Size and form of the signs must
      be conferred in advance with the landlord.

      The tenant is obligated to use collective signs facilities and to share
      proportionately in the costs.

      Labels, signs, advertisements, and such may be attached to windows only if
      the landlord has previously approved of this.

      If the landlord grants permission for the foregoing measures, number 2,
      paragraphs 2 through 4 (S) 13 number 2 of the AVG apply, correspondingly.
 
      Acoustic presentations that can be heard outside the rental rooms require
      the prior approval of the landlord.

(S) 4  Invoicing, reduction, damage reimbursement

1.    The tenant can withhold payment with respect to rental requirements only
      if his or her demands are uncontested or have been found to be legally
      valid and if he or she notified the landlord at least one month before the
      due date
<PAGE>
 
                                     - 5 -

     of the rent in writing.

2.   The reduction of the basic rent is not possible if the tenant must endure
     the impingement or if the impingement is not due to the landlord or if the
     fitness of the rental object for contractual use is only insignificantly or
     temporarily limited.

3.   The landlord is liable only for the damages incurred by the tenant,
     regardless of whether this is due to a deficiency in the rental object that
     already existed at the time of transfer, a deficiency that appeared only
     later, or whether the landlord is in delay of correcting the deficiency
     (unless the landlord has caused the damage intentionally or through gross
     negligence, or unless the deficiency was kept quiet deceptively by the
     tenant, or unless an assured characteristic is affected).

4.   The landlord provides no guarantee for uninterrupted operation of equipment
     of the rental object.

(S) 5  Rent

1.   Insofar as the tenant does not participate in a bank debit procedure, the
     rent must be paid every month in advance, at the latest on the third
     business day of the month, under identification via the

                            Rental Agreement Number

     and paid into the indicated account of the landlord without additional
     expense.

     With respect to determining punctuality of payment, not the sending but
     the receipt of the money (credit to the account) shall apply.

     If the tenant is in arrears of payment of rent, the landlord is
     authorized to apply a late fee.  Here, the landlord is authorized to charge
     a late fee in the amount of 4 % above the current annual discount rate.

     The landlord may, as he or she may decide, calculate payments based on
     costs and interest rates up to now or based on the oldest status.  This
     also applies if the tenant has found another condition.

2.   If the landlord declares him- or herself subject to value-added tax after
     the contract has been concluded then, in addition to rent, the value-added
     tax due must be paid by the tenant (if the tenant is an enterprise in the
     sales tax-related sense).

3.   Operational, elevator-related, and hot water-related cost prepayments will
     be calculated once per year.  The tenant is authorized, within 6 months of
     access to the
<PAGE>
 
                                     - 6 -

     invoicing, to see the invoice documents and to raise objections in writing
     against the claim.  If within the time limit no objections are raised, the
     invoice will apply as valid.

     If measuring or reading equipment should fall out of use or be impinged
     from proper functioning, or if for other compelling reasons the heating and
     hot-water usage cannot be determined in an official way, the cost
     distribution will take place as explained under (S) 9a of the Heating Cost
     Calculation Ordinance.

     The landlord can adjust the prepayments to be made by the tenant to the
     actual cost changes.

     If the tenant withdraws during an invoice period, there can be no claim
     to premature invoicing.  The cost distribution will take place in
     accordance with the measure of (S) 9b of the Heating Cost Invoice
     Ordinance.  The costs for the intermediary readings are to be borne by the
     tenant.

(S) 6  Operational costs

1.   Operational costs are those costs that arise on a continual basis for the
     landlord through ownership of the plot of land or through zoning-approved
     use of the building or of the business unit, side buildings, facilities,
     equipment, and the land:

     -    The total running public burdens of property, building, and business
          unit, property tax, garbage removal, chimney cleaning, canalization,
          water, and sewage.

     -    Insurance for property, building, and business unit against fire,
          storms, water damages, glass insurance, liability insurance for
          property, building, and business unit as well as for oil tanks and
          other technical equipment (e.g. elevators, air conditioners).

     -    Street cleaning, snow and ice removal as well as care and cleaning of
          all outside facilities such as yards, playgrounds, sidewalks, parking
          places, driveways, etc., including the devices and materials necessary
          for this as well as the replacement of plants and trees.

     -    Cleaning of property, building, and business unit including the
          community areas and rooms, outside glass and facade areas as well as
          insect prevention including devices and materials necessary for this.

     -    Operation and lighting of the community areas and rooms as well as
          community property, operation and maintenance
<PAGE>
 
                                     - 7 -

          of the elevators, escalators, revolving doors, electric doors, and
          other technical equipment including measuring equipment (in addition
          to setting them up); operation and maintenance of a community antenna
          as well as a connection to the broad-band cable network including any
          private distribution equipment necessary for this; operation and
          maintenance of sprinkler equipment and smoke removers as well as other
          community equipment.

     -    Building administration with a flat fee in the amount of 4% of the
          basic rent.

     -    Building administrator, building technician, as well as any security
          and any decorations and plant decor for the community areas.

2.    The billing of operational costs shall take place according to the
      relationship of the rental areas.  The landlord can change the invoicing
      key after an inexpensive measuring if an appropriate cost distribution or
      urgent reasons of official management demand it.

      The landlord can put neighboring buildings and/or properties together into
      one management and invoicing unit as well as separate buildings and/or
      properties that had previously been single invoicing units.

      The landlord can form invoicing groups according to type and use (office
      areas, store areas, garages) within a building or several buildings.

3.    If public expenditures must be reintroduced or if operational costs recur,
      the landlord is authorized to invoice these to the tenant as well.  This
      applies correspondingly to operational costs that have been invoiced
      retroactively to the tenant.

4.    If, in the course of using the rental rooms, raised operational costs
      emerge due to the tenant, e.g. through raised power or water consumption,
      etc., the tenant must also bear these costs.

5.    Operational costs for equipment that is specially present in only one
      rental object must be borne exclusively by the tenant.

6.    Commercially dependent waste must be disposed of by the tenant at his or
      her own expense.

(S) 7 Heating, hot water, and climate-control equipment
      - Operation and costs -

1.    Heating and hot water provision equipment as well as climate control
      equipment will be put into operation when needed. For disruptions, acts of
      God, official orders, or for any other reason that service cannot be
      provided (e.g. shortage of fuel,
<PAGE>
 
                                    - 8 -
  
     nondelivery of heating equipment, or strike), the landlord is not
     obligated to provide a replacement.  The landlord is liable for damages
     only in those instances arising from intent or gross negligence.

     In the case of independent, commercial provision of heat (heat supply)
     and hot water (hot water supply), these must take place subject to the
     conditions of the heat supplier.  The tenant will have no ongoing claims
     for damage reimbursement from the landlord and the heat supplier as the
     landlord may have with respect to the heat supplier.

2.   The tenant is obligated to cover costs in a proportionate share for the
     operation of facilities including fumes equipment, independently of to what
     extent he or she has used the facilities. Under this are included
     especially:

     -  the costs of consumed fuels and their delivery;

     -  the costs of heat supply;

     -  the costs of operations-related electricity;

     -  the costs for service, security, and maintenance of the equipment, of
        the regular testing of their operation-readiness and operational
        security, including the hiring of an expert and the cleaning of the
        equipment and the operational room;

     -  the costs of measurement under the Federal [illegible] Protection Act;

     -  the costs of reinforcement or other [illegible] of the sublet of
        equipment for consumption records as well as

     -  the costs of using equipment for consumption records including the costs
        of invoicing and distribution.

3.  Heating costs will be distributed in accordance with (S) 7 of the Ordinance
    on Heating Cost Calculation, in accordance with the recorded heating
    consumption and also in accordance with the relationship of the rented-out
    areas.  The landlord can change the schedule for splitting costs under
    inexpensive measurement if an appropriate cost distribution or urgent
    reasons for official management require it.  The landlord can contract a
    specialized company for invoicing.

    If, in the rental rooms, measurement-related equipment was installed for
    consumption records, the tenant must guarantee access to this measurement
    equipment during the standard day hours and make the equipment freely
    accessible.  If the reading of measures is not possible for the announced
    deadline for a reason due to a certain circumstance which the tenant has
    represented, the
<PAGE>
 
                                     - 9 -

      tenant has to bear any additional costs arising from this.

4.    the rules in No. 3 apply correspondingly as explained under (S) 8 of the
      Ordinance on Heating Cost Calculation for the costs of operation of the
      hot-water provision equipment and/or for the costs of the hot-water
      supply.

5.    The distribution of costs for providing heat and hot water for facilities
      subject to this contract will take place as described under (S) 9 of the
      Ordinance on Heating Costs Calculation.

6.    For the distribution of the costs of operation of climate control
      equipment, (S) 6 Nos. 2 and 4 will apply, respectively.


(S) 8 Rental Security deposit

1.    The rental security deposit agreed to will serve as security of all
      requirements stemming from this rental agreement relationship.

2.    If the rental security deposit is provided in the form of a guarantee,
      then this must be carried out through saving an unlimited self-debiting
      guarantee at a German bank with respect to the persuasiveness of the
      appeal, charge, advance accusation ((S)(S) 770, 771 Federal Law Register)
      and the right from (S) 776 Federal Law Registry.

3.    The rental security deposit must be supplied at the start of the rental
      period. The tenant will have no claim to transfer the rooms up to the time
      that the rental security deposit is furnished.

4.    The landlord is authorized, not obligated however, to deduct from the
      rental security deposit if the tenant is late in fulfilling his or her
      obligations.


(S) 9 Maintenance and use of the building as well as the rental rooms

1.    The landlord will take over the maintenance of the buildings in this
      building (outside maintenance) and will bear any costs here that may
      arise.

2.    The tenant will take over the maintenance and upkeep of the community
      property and the community technical equipment and facilities as well as
      parking places.

3.    The tenant must carry out the upkeep, maintenance and attention of the
      technical equipment that has been left to his or her exclusive use or that
      have been brought in by him or her, at his or her own expense. In
      addition, climate control facilities, elevators, escalators within the
      rental area, sanitary equipment, electric equipment, reinforcements, sun-
      protective equipment (inside and outside), thermostats, heat measurers,
      antenna equipment in particular, are a part of this. The landlord is
      authorized
<PAGE>
 
                                     - 10 -

       to require proof that such work has been carried out.  The landlord
       retains the right to subcontract out the work for the tenant.

       Damaged or destroyed glass sheets are to be replaced by the tenant at his
       or her own expense immediately.

4.     The tenant will bear the costs for beautification-related repairs. He or
       she must carry out required beautification-related repairs without
       special request by the landlord. These repairs include, in particular,
       all painting and tapestry works within the rental rooms as well as the
       professional upkeep of the floors and floor coverings.
 
       The tenant does not have the right to deviate from the rules above
       without the consent of the landlord.


5.     The tenant is obligated to clean the rental rooms professionally
       including industry-specific equipment. This refers, in addition, to fat
       cutters, filters, windows inside and out including the frames with the
       required [illegible] care, sun protection equipment, if necessary. If the
       cleaning can be performed only by the landlord due to construction-
       related or other reasons, then the tenant must endure and bear the costs
       of the work.


(S) 10 Construction-related measures by the landlord

1.     The landlord can, without the approval of the tenant, have work and
       construction-related measures performed for the improvement of the rental
       rooms or other parts of the building for the purposes of saving
       electricity and heat-related energy, for applying threatening procedures
       or for correcting damage. The tenant must keep the rooms coming into
       consideration here accessible and may not hinder the execution of work or
       delay it. The tenant is not authorized to terminate the contract under
       (S) 541b paragraph 2 sentence 2 of the Federal Law Registry.

2.     Insofar as the tenant must tolerate the measures, he or she can not
       demand reimbursement for his or her expenses. Reimbursement for damages
       can be demanded by the tenant only if the use of the rental rooms has
       been substantially impinged upon or made impossible by the measures.

(S) 11 Liability of the tenant

1.     If, for the duration of the rental relationship in or at the rental
       rooms, any deficiency exhibits itself for whose correction the tenant is
       not obligated or if precautions for the protection of the rental rooms
       against an unpredictable danger become necessary, then the tenant must
       inform the landlord of this immediately. If the tenant fails to provide a
       punctual notification, then he or she is obligated to cover costs for
       damage stemming from this and--insofar as the landlord was hindered from
       having the search for a remedy--is not authorized
<PAGE>
 
                                     - 11 -

       to make rent reduction claims valid and to announce this in accordance
       with (S) 542 paragraph 1 sentence 3 of the Federal Law Registry to demand
       reimbursement for damages due to nonfulfillment.

2.     The tenant is liable for all damages that are negligently caused by him
       or her, his or her fulfillment assistants, or third parties, insofar as
       these have come to his attention for being carried out with respect to
       the rental object.

       It is incumbent on the tenant to prove that neither he, she nor one of
       the aforementioned persons caused any damages.

(S) 12 Termination

1.     Termination of the contract must be carried out in writing up to the
       third business day of the first month of the termination deadline. In
       determining punctuality of termination, this does not depend on the
       sending but rather on the receipt of the termination notice.

2.     The landlord is authorized, regardless of other legal rules, to terminate
       the rental relationship without notice if the tenant

       -     is late for two successive deadlines submitting the monthly total
             payment or a substantial part of the total monthly payment, or

       -     has gone into arrears in the amount of a balance in a time period
             that extends over more than two deadlines with the submission of
             the total monthly payment--arrears that meet the total monthly
             payment for two months, or

       -     violates obligations under this contract in a culpable fashion and
             does not fulfill them within two weeks after receipt of a written
             reminder.


(S) 13 End of the rental period

1.     The landlord is authorized to hang rental notices in the area of the
       rental rooms before the expiration of the rental period.

2.     The tenant must correct installations and building-related changes that
       were undertaken before or after moving in before the end of the rental
       period; and must reestablish the original or predicated state. The
       landlord is authorized, however, to accept installations or building-
       related changes wholly or partly. The obligation to execute
       beautification repairs in accordance with (S) 9 will remain untouched by
       this.

3.     The rental rooms are to be returned to the landlord at the end of the
       rental period carefully cleaned, maintained, and in renovated state
<PAGE>
 
                                     - 12 -

    after performing the work named in No. 2, with all peripheral items and all
    keys.

    The landlord may demand a settlement in money for fulfilling this
    obligation.

    The amount of fulfillment in cash will be provided using one of the offers
    to be drawn up by a specialized firm.  Both parties to this contract are
    authorized to present a corresponding offer.  If no agreement can be
    reached, the offer of one of the specialized firms to be named by the local
    trade corporation will be binding for both parties to this contract.

4.  If rental rooms cannot be returned at the end of the rental period, the
    tenant is obligated to pay a use reimbursement fee in the amount of the
    previous and/or of the target rent.  If the tenant continues use of the
    rental rooms beyond the termination of the contract, then the rental
    relationship will not apply as automatically extended.  (S) 568 of the
    Federal Law Registry will find no application here.  Furthermore, the tenant
    must reimburse each instance of damage that the landlord incurs in not
    having the rental rooms returned to him or her punctually.

       The same will apply if the rental rooms are in a state consistent with
       the contract. The date on which the contractual state was produced will
       be assumed as the point in time of return.

5.     If the tenant returns or vacates the rental rooms before the end of the
       rental period, the landlord will be--regardless of the still-existing
       payment obligation of the tenant--authorized to undertake renovation and
       maintenance work as well as other construction-related measures within
       the rental rooms. The landlord may decorate restaurants or shop
       locations.

6.     If the rental relationship ends via termination without notice by the
       landlord, then the tenant is liable for all damages stemming from the
       termination, in particular any rent due. The liability will exist at its
       greatest up to the point in time at which the rental relationship could
       have been terminated within the context of an official termination.


(S) 14 Entering the rental rooms on the part of the landlord

The landlord, or his or her representative, may enter the rental rooms at
appropriate times of day to check on the state, to take readings of measurement
devices, to rent out the property again, or for any similar reasons--they may
also be accompanied by third parties.  The tenant must take care that the rental
rooms are in condition to be entered even in his or her absence.
<PAGE>
 
                                    -  13 -

(S) 15 Majority of tenants

1.     With a majority of tenants, each tenant is liable for the obligation
       under the rental agreement as a sole debtor.

2.     Business related legal declarations that affect the rental relationship
       must be submitted by or to all tenants.  While retaining the right to
       cancel in writing, the tenants, also however, authorize each other, until
       further notice, to accept or issue such declarations.  This authorization
       also applies to the acceptance of a termination, but not however to the
       submission of a declaration of termination and the conclusion of a rent
       cancellation contract.  A cancellation of the authorization enters into
       force only for declarations that were submitted after the receipt by the
       landlord.

3.     If the landlord must provide payments to the tenants, he or she can pay
       one of them on behalf of all of them.


(S) 16 Handling dangerous materials

Insofar as, and to whatever extent, the tenant may handle materials in the
rental object that tend to endanger health or the environment (e.g. materials
that are poisonous, damaging to ones health, flammable, infectious, explosive,
irritating, nauseating, carcinogenic, potentially water polluting), the tenant
is obligated to adhere without limitation and independently to all decisive
security regulations for the handling of these dangerous materials and to hold
the landlord harmless of all risks connected with these dangerous materials,
even after the expiration of the rental relationship.


(S) 17 Protection of personal data

The data necessary to carry out this rental agreement will be saved through data
processing at the landlord's place of business and will be transmitted, to the
extent necessary, within the context of the purpose of this contractual
relationship.

(S) 18 Applicability in the case of partial invalidity

If a term of this rental agreement is inapplicable or ceases to be an integral
component to this rental agreement, the rest of the contract shall remain in
force.  In this case, the parties to this contract will agree to a new rule that
comes closest to the original intent of the parties.
<PAGE>
 
                                    - 14 -

(S) 19  Court of jurisdiction

The court of jurisdiction is Wiesbaden insofar as this has been agreed to as
permissible.

(S) 20  Final terms

Oral side agreements will not apply.
Alterations and supplements to the rental contract must be performed in writing.
<PAGE>
 
Building ordinance for the rental agreement


The building ordinance serves to protect the house and insure its security and
that of its users.  Please adhere to these rules so that an orderly and
disruption-free coexistence is possible for all parties involved.

(S) 1  Mutual consideration

The common use of a building by tenants with different corporate structures and
in different branches of industry requires mutual consideration beyond a good
neighborly relationship.

Sound and smell disruptions must be avoided in the interest of all tenants.  For
this reason, all devices, machines, etc. whose operation causes noise must be
set up to reduce noise such that no transmission of noises into another rental
object can take place.

(S) 2  Storage of objects, fire protection

Stairwells and all other hallways, basement corridors, etc. that are provided
for common use have been designated as escape paths for the security of all
tenants in the case of fire.  These areas may under no circumstances--not even
temporarily--be used to store furniture, packaging items, wares and similar
things.

The storage of old paper and other easily flammable objects in the basement or
in the attic is not permitted.

Motorized vehicles may be parked only in those places identified for them.

(S) 3  Climate control, heating and sun protection equipment

In air-conditioned and heated rooms one must be careful that air circulation is
not impinged upon by inappropriate furnishing (e.g. by storing objects on top of
the air conditioner's vent openings or by placing office furniture too close to
climate control equipment).  The windows of air-conditioned and heated rooms
must be kept closed at all times.

Hand-operated sun protection equipment should be set up immediately whenever
there is wind or rain.

(S) 4  Elevators

Tenants who want to transport furniture or other heavy items can--insofar as no
special service elevator exists--make use of the elevator for persons with the
approval of the building administrator.  If necessary the elevator cabin must be
lined to protect it from damages.
<PAGE>
 
(S) 5  Garbage and refuse removal

Refuse may be collected only in suitable closed containers and emptied into
garbage bins.  Tenants whose area of business (e.g. restaurant) requires
additional garbage bins, must order these specially.

For special garbage, the normal garbage bins cannot be used.

Insofar as special collection stations are set up for old paper, packaging
materials, glass, etc. these are to be used by all tenants.

A garbage removal facility cannot have restricted refuse (cartons or other
packaging materials, bottles, etc.) with flammable or smoldering material or
liquids sent to it.

The tenants are obligated to sort their garbage according to different types
insofar as this is required by communal ordinances.

(S) 6  Frost protection

In order to avoid frost damages, the rental rooms are to be adequately heated
even outside of usual business hours.  Basement windows and ceiling holes are to
be kept closed during the frost period.

(S) 7  Building lockup

It is incumbent upon the tenants of the building to keep access closed from
o'clock in the evening through      o'clock in the morning and to confirm any
possible existing security issues.  During this time elevators may be put out of
service and stairwell lighting may be limited.

Basement and courtyard doors as well as doors to communal garages are to be kept
closed at all times.

(S) 8  Additional rules

The tenants must adhere to official regulations (in particular to those of
building and fire police as well as to industrial supervisors).

The tenants will take care that the building ordinance is followed by their
employees, sublessors, suppliers, visitors, etc. as well as any tradesmen
employed by them.

The building ordinance and other ordinances drawn up for the operation or the
use of community property can be altered by the landlord.  The alterations must
be made known to the tenants.

                             EMPLOYMENT AGREEMENT
