                               PROSPECTUS SUMMARY

     This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus carefully, including the section entitled
"Risk Factors," our financial statements and the related notes included
elsewhere in this prospectus, before making an investment decision.

                        CHAPARRAL NETWORK STORAGE, INC.
                               ------------------

     We are a leading provider of high performance products that facilitate the
movement of data between networked storage devices. We are focused primarily on
developing products for use in the emerging market for Storage Area Networks, or
SANs. SANs are high-speed data networks that interconnect storage systems and
servers using a widely accepted protocol known as Fibre Channel.

     Our products include storage routers and external Redundant Array of
Independent Disks, or RAID, controllers for open systems network storage
solutions. Storage routers connect servers and storage systems in a SAN to
enable communication among devices that use different protocols for the
input/output, or I/O, of data. RAID controllers distribute blocks of data across
multiple disks to improve performance and ensure availability of data.

     In the last decade, there has been a dramatic increase in the volume of
data created, processed and accessed throughout the business enterprise. This
growth has placed a significant strain on storage systems used in the backup,
sharing and management of this data. In addition, organizations have recognized
the importance and value of enterprise data as mission-critical to their
employees, customers and suppliers and are demanding rapid and reliable access
to data 24 hours a day, seven days a week. The congestion caused by users trying
to access large amounts of data across local area networks, or LANs, has created
a bottleneck between the server and the storage devices. The limitations of
today's most commonly used server-attached storage architecture, where storage
devices are typically connected to only one server using an I/O protocol called
the Small Computer System Interface, or SCSI, have exacerbated this bottleneck.
As a result, enterprises are demanding a faster, more efficient and manageable
means to interconnect new and existing servers, storage devices and LANs.

     Our Intelligent Storage Routers facilitate the interconnection of SANs with
existing SCSI-based servers and storage systems. Our external RAID controllers
dynamically distribute data across multiple hard disk drives to increase data
transfer speeds and deliver fault tolerance. Our products are designed to
provide a high level of performance, availability and functionality. They
incorporate a common high-performance hardware platform and foundation software
layer that enable a wide range of SAN applications.

     Key benefits of our solutions include the following:

     - Increased Performance. We believe our products provide industry-leading
       performance and functionality for SAN-attached disk, tape and library
       storage devices.

     - High Availability and Reliability. Our products increase the
       accessibility and protection of enterprise data by providing redundant
       I/O paths to storage devices.

     - Improved SAN Performance with New Applications. Our products are designed
       using a highly flexible and modular embedded software architecture,
       enabling us to quickly and cost-effectively implement new SAN
       applications.

     - Differentiation and Manageability. We have developed a robust,
       well-defined user interface called a Common Application Programming
       Interface, or CAPI, that enables our customers to incorporate their
       proprietary functionalities into our products to differentiate their
       solutions in the market. In addition, our customers can design their own
       graphical user interface, or GUI, to manage our equipment in conjunction
       with their solutions.

                                        5

     We sell our products to original equipment manufacturers, or OEMs,
including Eurologic Systems, MicroNet Technology, Inc., Qualstar Corporation,
Quantum Corporation/ATL Products, Inc., Trimm Technologies, Inc. and Xyratex
International Ltd., as well as to distribution partners, including Arrow
Electronics, Inc., Bell Microproducts, Inc. and CONSAN Inc. Through December 31,
1999, we sold approximately 4,500 units of our Intelligent Storage Routers and
external RAID controllers.

     We intend to capitalize on our Fibre Channel technological expertise to
address the growing SAN market. In addition, we will continue to focus on
expanding and developing distribution relationships with leading computer and
storage systems OEMs, as well as with value added resellers and systems
integrators, to increase our geographic coverage and address new markets. We
intend to continue to work closely with our strategic partners and participate
in industry alliances to facilitate the widespread adoption of SANs and SAN
applications.

     We were incorporated in January 1998 as Chaparral Technologies, Inc., a
Delaware corporation. In July 1999, we changed our name to Chaparral Network
Storage, Inc. to reflect our emphasis on providing network storage products. Our
principal executive offices are located at 1951 S. Fordham Street, Longmont,
Colorado 80503, and our telephone number is (303) 684-3200. The address of our
Web site is www.chaparralnet.com. Information contained on our Web site should

                                  RISK FACTORS

     An investment in our common stock is very risky. You should carefully
consider the risks described below, together with all of the other information
in this prospectus, before making a decision to invest in our common stock.

                     RISKS RELATED TO OUR FINANCIAL RESULTS

WE HAVE INCURRED SIGNIFICANT LOSSES SINCE OUR INCEPTION, WE EXPECT FUTURE LOSSES
AND WE MAY NEVER BECOME PROFITABLE.

     We have incurred significant losses since our inception and expect to
continue to incur losses on both a quarterly and annual basis for the
foreseeable future. As of December 31, 1999, our accumulated deficit was
approximately $8.4 million. For the fiscal year ended March 31, 1999, our net
loss was approximately $3.7 million, and for the nine months ended December 31,
1999, our net loss was approximately $4.7 million. We expect to incur
significant research and development, sales and marketing and administrative
expenses and, as a result, we will need to realize increased revenue to achieve
profitability. Further, even if we achieve profitability, given the competition
in and the evolving nature of the SAN market, we may not be able to sustain or
increase profitability on a quarterly or annual basis.

OUR LIMITED OPERATING HISTORY MAKES FORECASTING DIFFICULT AND PROVIDES LIMITED
INFORMATION UPON WHICH TO EVALUATE OUR BUSINESS.

     We were incorporated in January 1998 and sold our first product in October
1998. To date, most of our revenue has been derived from the sale of our
external RAID controllers. Our business is evolving, and we expect to derive an
increasing portion of our future revenue from the sale of our Intelligent
Storage Routers. The revenue and income potential of our products and businesses
are unproven and the market that we are addressing is rapidly evolving, making
the forecast of our future business difficult. In addition, our operating
expenses are largely based on anticipated revenue trends and a high percentage
of our expenses are, and will continue to be, fixed in the short-term. Our
limited operating history and our evolving business make it very difficult for
us and for investors to evaluate or predict our future revenue or business
prospects. For further financial information relating to our business, see
"Selected Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

WE HAVE A HISTORY OF FLUCTUATIONS IN OUR REVENUE AND OPERATING RESULTS, AND
EXPECT THESE FLUCTUATIONS TO CONTINUE, WHICH MAY RESULT IN VOLATILITY IN OUR
STOCK PRICE.

     Our revenue and operating results have varied significantly in the past and
are likely to vary significantly in the future due to a number of factors, many
of which are outside of our control. The primary factors that may cause our
quarterly revenue and operating results to fluctuate include the following:

     - fluctuations in demand for our Intelligent Storage Routers and external
       RAID controllers;

     - the size, timing, terms and fluctuations of customer orders and product
       implementations;

     - the rate of adoption of SANs as an alternative to existing
       server-attached storage architectures;

     - the mix of our Intelligent Storage Routers and external RAID controllers
       sold;

     - the mix of distribution channels through which our products are sold;

     - new product introductions by us or our competitors;

     - deferrals of customer orders in anticipation of new products, services or
       product enhancements introduced by us, our OEMs, our competitors or from
       other providers of SAN products;

     - changes in our pricing policies or the pricing policies of our
       competitors;

                                        8
<PAGE>   10

     - our ability to develop, introduce, ship and support new products and
       product enhancements that meet customer requirements in a timely manner;

     - prototype expenses;

     - our ability to obtain sufficient supplies of components, including sole
       or limited source components;

     - increases in the prices of the components we purchase;

     - our ability to attain and maintain production volumes and quality levels;

     - the ability of our contract manufacturers to produce and distribute our
       products in a timely fashion;

     - the software enhancements embedded in our hardware platforms;

     - the additional software options incorporated in our products;

     - costs related to acquisitions of technology or businesses; and

     - general economic conditions as well as those specific to the SAN and
       related industries.

     Accordingly, you should not rely on the results of any past periods as an
indication of our future performance. In future periods our operating results
may be below expectations of public market analysts or investors.

IF WE CANNOT INCREASE OUR SALES VOLUMES, REDUCE OUR COSTS OR INTRODUCE HIGHER
MARGIN PRODUCTS TO OFFSET ANTICIPATED REDUCTIONS IN THE AVERAGE SELLING PRICES
OF OUR PRODUCTS, OUR OPERATING RESULTS MAY SUFFER.

     We anticipate that as products in the SAN market become widely available,
the average selling prices of our products may decrease in response to changes
in product mix, competitive pricing pressures, new product introductions by us
or our competitors or other factors. If we are unable to offset the anticipated
decrease in our average selling prices by increasing our sales volumes, our
revenue will decline. In addition, to maintain our gross margin, we must
continue to reduce the manufacturing cost of our products and develop and
introduce new, higher margin products and product enhancements. If we cannot
maintain our gross margin, our business could be seriously harmed.

                         RISKS RELATED TO OUR INDUSTRY

THE SAN MARKET IN WHICH WE COMPETE IS NEW AND UNPREDICTABLE, AND IF THIS MARKET
DOES NOT DEVELOP AND EXPAND AS WE ANTICIPATE, OUR BUSINESS WILL SUFFER.

     Widespread adoption of SANs is critical to our future success. The market
for SANs has only recently begun to develop and is rapidly evolving. Because the
market for SAN products is relatively new, it is difficult to predict its
potential size and evolution and, as a result, we may not be able to forecast
accurately demand for our products. Furthermore, potential end users may be
reluctant or slow to adopt new storage architectures. Our success in generating
revenue in this emerging market will depend on, among other things, our ability
to:

     - educate potential OEM customers, distribution channel partners and end
       users about the benefits of SANs, storage routers and external RAID
       controllers;

     - achieve interoperability between our products and those of other SAN
       vendors;

     - develop, maintain and build relationships with OEM customers,
       distributors, resellers, systems integrators and end-user organizations;
       and

     - develop products that are compliant with existing and evolving standard
       protocols.

                                        9
<PAGE>   11

     In addition, end users often implement SANs in connection with their
deployment of new storage systems and servers. Accordingly, our future success
is also substantially dependent on demand for new storage systems and servers.

WE EXPECT TO FACE COMPETITION FROM MANUFACTURERS OF STORAGE SYSTEMS THAT
INCORPORATE FIBRE CHANNEL INTERFACES INTO THEIR PRODUCTS.

     We currently derive a substantial portion of our revenue from our
Intelligent Storage Routers, which are used to connect SCSI-based storage
systems with SANs. The introduction of storage systems that incorporate Fibre
Channel interfaces would enable storage devices to communicate directly with
SANs, without having to use storage routers. We expect that a number of
manufacturers of storage systems will develop products with embedded Fibre
Channel interfaces in the near future. If this occurs, demand for our
Intelligent Storage Routers could be materially reduced and our revenue may
decline.

THE SAN MARKET IS CHARACTERIZED BY RAPID TECHNOLOGICAL CHANGES AND EVOLVING
STANDARDS, AND IF WE DO NOT RESPOND IN A TIMELY MANNER, OUR BUSINESS COULD BE
HARMED.

     The SAN market is characterized by rapid technological change, frequent new
product introductions, changes in customer requirements and evolving industry
standards. In developing our products, we have made, and will continue to make,
assumptions regarding which standards will be widely adopted. If the standards
adopted are different from those we have chosen to support, market acceptance of
our products may be significantly reduced or delayed, our competitive position
may be compromised, our existing products may be rendered obsolete and our
business may be seriously harmed. In addition, our research and development
efforts associated with the technologies and standards that do not achieve
widespread adoption would likely have no realizable value. Even if we are
successful in predicting the adopted technologies and standards, any delay in
our development of products based on these technologies and standards would
likely result in lower revenue for our products than we anticipate.

                       RISKS ASSOCIATED WITH OUR BUSINESS

THE LOSS OF OR SIGNIFICANT REDUCTION IN SALES TO ANY OF OUR OEM CUSTOMERS, WHICH
HAS HAPPENED IN THE PAST, COULD SIGNIFICANTLY REDUCE OUR REVENUE.

     Our revenues are currently derived primarily from a small number of OEM
customers. For the nine months ended December 31, 1999, approximately 57% of our
revenue came from three OEM customers, nStor, Quantum/ATL and Eurologics. We
anticipate that our operating results will continue to depend on sales to a
relatively small number of OEM customers. None of our current customers have any
minimum purchase obligations, and they may stop placing orders with us at any
time, regardless of any forecast they may have previously provided. The loss of
any of our OEM customers, or a significant reduction in sales to these
customers, could significantly reduce our revenue.

     For example, during the quarter ended December 31, 1999, nStor, our largest
customer in the nine months ended December 31, 1999, returned approximately
$400,000 of our external RAID controllers following an order cancellation by one
of its customers. Although we had shipped these products to nStor in the quarter
ended December 31, 1999, pursuant to a noncancellable purchase order, we chose
not to recognize this revenue. We have not waived any claims arising from
nStor's cancellation of this order. Also, due to this cancellation, we did not
ship additional product pursuant to other nStor noncancellable purchase orders
for approximately $547,000. Primarily as a result of the cancellation of this
order and our decision not to ship additional products to nStor, our revenue for
the quarter ended December 31, 1999 decreased approximately 28% from the
previous quarter. We are not currently shipping to nStor, have received no new
purchase orders from nStor and may not ship to them in the future.

                                       10
<PAGE>   12

OUR STRATEGY DEPENDS ON DEVELOPING RELATIONSHIPS WITH NEW OEM CUSTOMERS, WHICH
IS A LENGTHY PROCESS THAT MAY IMPEDE THE GROWTH OF OUR REVENUE.

     Our success depends on our ability to initiate, manage and expand our
relationships with new OEM customers. OEMs typically conduct significant
evaluation, testing, implementation and acceptance procedures before they begin
to market and sell new products. Based on our experience, their evaluation
process can be lengthy and can take as long as one year. Additionally, some OEMs
may complete the evaluation of our products but choose to delay implementation.
The qualification process is also complex and may require significant sales,
marketing and management efforts on our part. The complexity of this process
increases if we must qualify our products with multiple customers concurrently.
As a result, we may expend significant resources in developing customer
relationships before recognizing revenue, if any.

OUR STRATEGY DEPENDS ON DEVELOPING RELATIONSHIPS WITH NEW DISTRIBUTORS.

     In addition to increasing sales to OEMs, we intend to develop and expand
indirect distribution channels. Our failure to execute this strategy could limit
our ability to grow or sustain revenue. Furthermore, as we expand our sales to
distributors, we will increase our selling costs as these parties generally
require a higher level of customer support than OEMs. Our distributors may not
market our products effectively or devote the resources necessary to provide us
with effective sales, marketing and technical support. Many of our distributors
also sell products that compete with our products. Our failure to successfully
manage our distributor relationships, or their failure to devote adequate
resources to marketing and selling our products, could limit our ability to grow
or sustain our revenue.

COMPETITION IN OUR MARKETS MAY ADVERSELY AFFECT OUR REVENUE, GROSS PROFIT AND
MARKET SHARE.

     The market for our products is very competitive. In the external RAID
controller market, our current competitors include CMD Technology, Inc.,
Infotrend Corporation and Mylex Corporation (acquired by IBM Corporation). As we
start selling higher performance RAID products targeted at the enterprise
market, we will face competition from larger and more established companies that
offer more integrated solutions, such as Data General (acquired by EMC
Corporation) and Symbios Logic (acquired by LSI Logic Corporation). In addition
to these companies, we expect to see competition from existing internal RAID
suppliers, such as American Megatrends Inc. and Distributed Processing
Technology (recently acquired by Adaptec, Inc.). Our major competitors in the
storage router market are ATTO Technology, Inc., CrossRoads Systems, Inc. and
Pathlight Technology, Inc. In the future, we may also compete against large data
networking companies that may develop SAN products. Furthermore, we may face
competition from Fibre Channel switch and hub manufacturers that incorporate
storage routing capabilities into their products. We also compete with providers
of data storage solutions that employ traditional storage technologies,
including SCSI-based technology, such as Emulex Corporation and QLogic
Corporation.

     Increased competition could result in pricing pressures or reduced sales,
margins, profits and market share. Some of our competitors and potential
competitors have longer operating histories, greater name recognition, access to
larger customer bases, more established distribution channels or substantially
greater resources than we have. In addition, some of our current and potential
competitors have already established supplier or joint development relationships
with divisions of our current or potential customers. These competitors may be
able to leverage their existing relationships to discourage these customers from
purchasing additional products from us or persuade them to replace our products
with their products. As a result, they may be able to respond more quickly than
we can to new or changing opportunities, technologies, standards or customer
requirements. Our inability to compete effectively against current or future
competitors may significantly harm our business.

                                       11
<PAGE>   13

WE HAVE LIMITED PRODUCT OFFERINGS, AND OUR SUCCESS DEPENDS ON OUR ABILITY TO
DEVELOP NEW AND ENHANCED PRODUCTS THAT ACHIEVE MARKET ACCEPTANCE.

     We derive a substantial portion of our revenue from a limited number of
products, some of which have been introduced and shipped in volume only
recently. Accordingly, market demand and acceptance of these products are
uncertain. Our future success depends upon our ability to address the rapidly
evolving SAN market by developing and introducing high-quality products, product
enhancements and services on a timely basis. In addition, we must successfully
manage the introduction of new or enhanced products to minimize disruption in
our customers' ordering patterns, avoid excessive levels of older product
inventories and ensure that adequate supplies of new products can be delivered
to meet our customers' demands. Our revenue may be reduced if our current
products do not obtain market acceptance or if we fail to develop new products
or product enhancements that are broadly accepted.

     Factors that may affect the market acceptance of our products, some of
which are beyond our control, include the following:

     - growth and changing requirements of our markets;

     - successful development of products that meet customer requirements;

     - availability, price, quality and performance of competing products and
       technologies;

     - expansion of our relationships with existing and new OEM, distributor,
       reseller and systems integrator customers;

     - performance, quality, price and total cost of ownership of our products;
       and

     - our customer service and support capabilities and responsiveness.

PRODUCT DEVELOPMENT DELAYS COULD SIGNIFICANTLY HARM OUR BUSINESS.

     We may not be able to develop, manufacture and market new products or
product enhancements in a timely manner. Product development delays may result
from numerous factors, including:

     - unanticipated engineering complexities;

     - changing market or competitive product requirements;

     - changing OEM product specifications;

     - difficulties with independent contractors;

     - difficulties in hiring and retaining necessary personnel;

     - difficulties in overcoming resource limitations; and

     - inability to license third party technology.

Any delay or unanticipated difficulty associated with new product introductions
or product enhancements could significantly harm our business, results of
operations and financial condition.

BECAUSE WE DEPEND ON SOLE AND LIMITED SOURCE SUPPLIERS FOR KEY COMPONENTS, WE
ARE SUSCEPTIBLE TO SUPPLY SHORTAGES THAT COULD ADVERSELY AFFECT OUR OPERATING
RESULTS.

     We depend on Adaptec for our Fibre Channel, SCSI and memory controller
Application Specific Integrated Circuits, or ASICs. In addition, we have limited
supply sources for several key components, including embedded microprocessors,
optical transceivers and power supplies. We may in the future experience
shortages of, or difficulties in acquiring, these components. If we are unable
to buy these components in sufficient quantities, we will not be able to
manufacture our products on a timely basis. We typically purchase three months
of these components in advance and consign these parts to our outsourced

                                       12
<PAGE>   14

manufacturers. If we are required to procure and qualify alternative sources of
supply, we may face both cost increases and time to market delays resulting from
the need to redesign our hardware platforms.

IF OUR CONTRACT MANUFACTURERS ARE UNABLE TO MEET OUR MANUFACTURING NEEDS, OUR
REVENUE MAY SUFFER BECAUSE WE MAY NOT BE ABLE TO MEET OUR CUSTOMER DEMAND.

     We currently outsource manufacturing of our products to Surface Mount
Technology Centre Inc. (SMTC) and Saturn Electronics & Engineering, Inc.
(Saturn). We share our contract manufacturers' capacity with numerous companies
whose manufacturing needs may conflict with ours. Our contract manufacturers are
not obligated to supply products to us for any specific period, or in any
specific quantity, except as may be provided in a particular purchase order that
has been accepted by them. If either of our contract manufacturers experiences
delays, disruptions, capacity constraints or quality control problems in its
manufacturing operations, then product shipments to our customers could be
delayed, which could negatively impact our revenue, competitive position and
reputation.

     Further, our business would be harmed if we fail to manage the
manufacturing of our products effectively. We generally place firm orders with
our contract manufacturers at least three months prior to scheduled delivery of
products to our customers. Accordingly, if we inaccurately forecast demand for
our products, we may be unable to obtain adequate manufacturing capacity or
adequate quantities of components to meet our customers' delivery requirements
or we may accumulate excess inventories.

     We may in the future need or choose to select new contract manufacturers
for volume, cost or quality considerations. We may not find a contract
manufacturer that meets our requirements. Additionally, qualifying a new
contract manufacturer and commencing volume production is expensive and time
consuming.

IF WE ARE UNABLE TO FORECAST ACCURATELY OUR COMPONENT AND MATERIAL REQUIREMENTS,
WE MAY INCUR ADDED COSTS OR BE UNABLE TO MEET CUSTOMER DEMANDS.

     We use rolling forecasts based on anticipated product orders from our
customers to determine our component requirements. Lead times for materials and
components that we order vary significantly and depend on factors, such as
specific supplier requirements, contract terms and current market demand for
such components. As a result, we may not accurately forecast our component
requirements. If we overestimate our component requirements, we could have
excess inventory, which would increase our costs. If we underestimate our
component requirements, we may have inadequate inventory, which could interrupt
our manufacturing and delay delivery of our products to our customers. Either
occurrence would negatively impact our business and operating results.

OUR PRODUCTS ARE COMPLEX AND MAY CONTAIN UNDETECTED SOFTWARE OR HARDWARE ERRORS,
WHICH COULD LEAD TO AN INCREASE IN OUR COSTS OR A REDUCTION IN OUR REVENUE.

     Our products are complex, and we have, from time to time, found errors in
our existing products. We also may in the future find errors in our existing,
new or enhanced products. Because our products are also integrated with products
from other vendors, it may be difficult to identify the source of any problem.
Hardware and software errors, whether caused by our products or those of another
vendor, could adversely affect sales of our products, cause us to incur
significant warranty and repair costs, divert engineering resources from product
development efforts and cause significant customer relations problems.

IF WE DO NOT HIRE, RETAIN AND INTEGRATE HIGHLY SKILLED PERSONNEL, OUR BUSINESS
MAY SUFFER.

     Our success depends to a significant degree on our personnel, many of whom
would be difficult to replace. Currently, we only have employment contracts with
our three most senior executives and do not maintain key person life insurance
on any of our personnel. The loss of any of our key personnel could have a
negative impact on our business.

                                       13
<PAGE>   15

     We believe our future success will also depend in large part upon our
ability to attract and retain highly skilled personnel. Competition for these
people is intense, and we may not be successful in attracting and retaining
these individuals. If we are unable to attract or retain qualified personnel in
the future, or if we experience delays in hiring required personnel,
particularly qualified engineers and sales personnel, our ability to develop,
introduce and sell our products could be harmed. In addition, we may be subject
to claims of unfair hiring practices as we pursue highly skilled personnel. Any
claim of this nature could result in material litigation. We could incur
substantial costs in defending ourselves against these claims, regardless of
their merits.

     We also believe that our success depends significantly on the ability of
our personnel to operate effectively, both individually and as a group. Many of
our employees have only recently joined us. If we are unable to integrate new
employees in a timely and cost-effective manner, our operating results may
suffer.

IF WE ARE UNABLE TO MANAGE OUR GROWTH SUCCESSFULLY, OUR BUSINESS MAY SUFFER.

     We have grown to 61 employees as of December 31, 1999, from eight employees
as of March 31, 1998. We plan to continue to expand our operations significantly
to pursue existing and potential market opportunities. This growth will place a
significant demand on our management and operational resources. In order to
manage our growth effectively, we must implement and improve our operational
systems, procedures and controls on a timely basis. If we fail to manage our
growth effectively or make mistakes in operating our business, we may experience
fluctuations in our operating results or declines in our stock price or both.

WE MAY ENGAGE IN ACQUISITIONS THAT DILUTE OUR STOCKHOLDERS' EQUITY AND CAUSE US
TO INCUR DEBT OR ASSUME CONTINGENT LIABILITIES.

     We expect to review opportunities to buy other businesses or technologies
that would complement our current products, expand our market opportunity or
enhance our technical capabilities. We have no current agreements or
negotiations underway. In the event of any future acquisitions, we could incur
debt, assume liabilities or issue stock. The issuance of stock would dilute our
current stockholders' percentage ownership.

     Acquisitions could also involve numerous risks, including:

     - problems integrating the purchased operations, technologies or products
       with our existing business and products;

     - unanticipated costs;

     - diversion of management's attention from our core business;

     - adverse effects on existing business relationships with our suppliers and
       customers;

     - incorrect estimates made in the accounting for acquisitions;

     - risks associated with entering markets in which we have no or limited
       prior experience; and

     - potential loss of key employees within our company or any business we
       acquire.

     We may not be able to integrate successfully any businesses, products,
technologies or personnel that we acquire.

IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY ADEQUATELY, OUR OPERATING
RESULTS COULD SUFFER.

     Because our products rely on proprietary technology and will likely
continue to rely on technological advancements for market acceptance, we believe
that the protection of our intellectual property rights will be critical to the
success of our business. To protect our intellectual property rights, we rely on
a combination of patent, copyright, trademark and trade secret laws and
restrictions on disclosure. We also
                                       14
<PAGE>   16

enter into confidentiality or license agreements with our employees, consultants
and corporate partners and control access to and distribution of our software,
documentation and other proprietary information.

     Despite our efforts to protect our proprietary rights, unauthorized parties
may copy or otherwise obtain and use our products or technology. Monitoring
unauthorized use of our products is difficult. We cannot be certain that the
steps we take to protect our intellectual property will adequately protect our
proprietary rights, that others will not independently develop or otherwise
acquire equivalent or superior technology or that we can maintain any of our
technology as trade secrets. We license the core technology that underlies our
products from Adaptec, and we depend on Adaptec to enforce its patents and
protect our proprietary rights. We cannot be certain that Adaptec will
adequately enforce these patents. In addition, the laws of some of the countries
in which our products are or may be sold may not protect our products and
intellectual property rights to the same extent as the laws of the United States
or at all. For a more complete discussion of the protection of our intellectual
property, see "Business  -- Intellectual Property." Our failure to protect our
intellectual property rights could adversely affect our business, results of
operations and financial condition.

WE RELY HEAVILY ON OUR INTELLECTUAL PROPERTY, AND CHALLENGES TO OUR INTELLECTUAL
PROPERTY RIGHTS MAY RESULT IN LITIGATION, INCREASED COSTS AND PRODUCT DELAYS.

     In recent years, there has been significant litigation in the United States
involving patents, trademarks and other intellectual property rights. Although
we are not currently involved in any intellectual property litigation, we may be
a party to litigation in the future either to protect our intellectual property
or as a result of an alleged infringement of others' intellectual property.
These claims and any resulting litigation could subject us to significant
liability for damages and could cause our proprietary rights to be invalidated.
Regardless of the merits of the claim or outcome, litigation would likely be
time-consuming and expensive to resolve and would divert management time and
attention. Any potential intellectual property litigation could also force us to
do one or more of the following:

     - stop using the challenged intellectual property or selling our products
       or services that incorporate it;

     - obtain a license to use the challenged intellectual property or to sell
       products or services that incorporate it, which license may not be
       available on reasonable terms, or at all; and

     - redesign those products or services that are based on or incorporate the
       challenged intellectual property.

     If we are forced to take any of the foregoing actions, we may be unable to
manufacture and sell our products, and our business could be substantially
harmed.

WE PLAN TO INCREASE OUR INTERNATIONAL SALES ACTIVITIES, WHICH WILL SUBJECT US TO
ADDITIONAL BUSINESS RISKS.

     For the nine months ended December 31, 1999, approximately 22% of our
revenue was from international sales. We plan to increase our international
sales activities. Our international sales will be limited if we cannot establish
relationships with international distributors, establish additional foreign
operations, expand international sales channel management, hire additional
personnel and develop relationships with international service providers. Even
if we are able to successfully continue international operations, we may not be
able to maintain or increase international market demand for our products. Our
international operations are subject to a number of risks, including:

     - increased complexity and costs of managing international operations;

     - multiple protectionist, adverse and changing governmental laws and
       regulations;

     - reduced or limited protection of intellectual property rights;

     - potentially adverse tax consequences resulting from changes in tax laws;

     - longer sales cycles;

                                       15
<PAGE>   17

     - greater difficulty in accounts receivable collection and longer
       collection periods;

     - supporting multiple languages;

     - difficulty enforcing our legal rights; and

     - political and economic instability.

These factors and others could harm future sales of our products to
international customers, which would negatively impact our business and
operating results.

     To date, none of our international revenue and costs have been denominated
in foreign currencies. As a result, an increase in the value of the U.S. dollar
relative to foreign currencies could make our products more expensive and thus
less competitive in foreign markets. A portion of our international revenue may
be denominated in foreign currencies in the future, which would subject us to
risks associated with fluctuations in those foreign currencies.

TO MANAGE OUR GROWTH AND EXPANSION, WE PLAN TO RELOCATE TO NEW FACILITIES, WHICH
MAY DISRUPT OUR BUSINESS.

     We plan to relocate our principal executive offices to a larger facility in
the second calendar quarter of 2000. This relocation could be disruptive,
time-consuming and expensive. If we experience delays or difficulties in
relocating, our ability to effectively manage our operations may be compromised.

WE MAY BECOME INVOLVED IN COSTLY AND TIME-CONSUMING LITIGATION THAT MAY
SUBSTANTIALLY INCREASE OUR COSTS AND HARM OUR BUSINESS.

     We may from time to time become involved in various lawsuits and legal
proceedings that arise from actions taken in the ordinary course of our
business. Litigation is subject to inherent uncertainties, and an adverse result
in litigation matters that may arise from time-to-time may harm our business.

OUR PRINCIPAL STOCKHOLDERS HAVE SIGNIFICANT VOTING POWER AND MAY TAKE ACTIONS
THAT ARE NOT IN THE INTERESTS OF OUR OTHER STOCKHOLDERS.

     We anticipate that the executive officers and directors and the 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, may be able to influence
significantly all matters requiring approval by our stockholders, including the
election of directors and the approval of mergers or other business
combinations, which may not be in the interests of all stockholders. For a full
presentation of the equity ownership of these stockholders, see "Principal
Stockholders."

                         RISKS RELATED TO THIS OFFERING

OUR MANAGEMENT CAN SPEND THE NET PROCEEDS FROM THIS OFFERING IN WAYS WITH WHICH
OUR STOCKHOLDERS MAY NOT AGREE.

     Our management can spend the net proceeds from this offering in ways with
which our stockholders may not agree. We cannot assure you that our investments
and the use of the net proceeds of this offering will yield favorable returns or
results. See "Use of Proceeds."

YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION IN THE BOOK VALUE OF YOUR
SHARES.

     The initial public offering price is substantially higher than the book
value per share of our outstanding common stock immediately after the offering.
Accordingly, if you purchase common stock in the offering, you will incur
immediate dilution of approximately $     in the book value per share of our
common stock from the price you pay for our common stock. For additional
information on this calculation, see "Dilution."

PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW COULD PREVENT OR DELAY A
CHANGE IN CONTROL OF OUR COMPANY AND MAY REDUCE THE MARKET PRICE OF OUR COMMON
STOCK.

     Provisions of our amended and restated certificate of incorporation or
bylaws may discourage, delay or prevent a merger with, or acquisition of, us
that a stockholder may consider favorable. These provisions include:

     - authorizing our board of directors to issue preferred stock without
       stockholder approval;

     - providing for a classified board of directors with staggered, three-year
       terms;

     - requiring super-majority voting to effect significant amendments to our
       certificate of incorporation and bylaws;

     - limiting the ability of stockholders to call special meetings; and

     - prohibiting stockholder actions by written consent.

     Certain provisions of Delaware law also may discourage, delay or prevent
someone from acquiring or merging with us, which may cause the market price of
our common stock to decline. For example, Delaware law prohibits cumulative
voting in the election of directors unless specifically provided for in the
certificate of incorporation.

OUR STOCK PRICE MAY BE VOLATILE AND YOU MAY NOT BE ABLE TO RESELL YOUR SHARES AT
OR ABOVE THE INITIAL PUBLIC OFFERING PRICE.

     There has been no public market for our common stock prior to this
offering. The initial public offering price for our common stock will be
determined through negotiations between the underwriters and us. This initial
public offering price may vary from the market price of our common stock after
the offering. If you purchase shares of common stock, you may not be able to
resell those shares at or above the initial public offering price. The market
price of our common stock may fluctuate significantly in response to factors,
some of which are beyond our control, including the following:

     - actual or anticipated fluctuations in our operating results;

     - changes in market valuations of other technology companies, particularly
       those that sell products used in SANs;

     - changes in financial estimates by securities analysts or our failure to
       perform in line with such estimates;

     - announcements by us or our competitors of significant technical
       innovations, contracts, acquisitions, strategic partnerships, joint
       ventures or capital commitments;

     - losses of major OEM customers, value added resellers or distributors;

     - introduction of technologies or product enhancements that reduce the need
       for our Intelligent Storage Routers and external RAID controllers; and

     - additions or departures of key personnel.

     In addition, the stock market has experienced extreme volatility that often
has been unrelated to the performance of particular companies. These market
fluctuations may cause our stock price to fall regardless of our performance.

     You should read the "Underwriting" section for a more complete discussion
of the factors that were considered in determining the initial public offering
price of our common stock.

SUBSTANTIAL FUTURE SALES OF OUR COMMON STOCK IN THE PUBLIC MARKET MAY DEPRESS
OUR STOCK PRICE.

     Our current stockholders hold a substantial number of shares that they will
be able to sell in the public market in the near future after the expiration of
applicable lock-up agreements. Sales of a substantial number of shares of our
common stock after this offering could cause our stock price to fall. In
addition, the sale of these shares could impair our ability to raise capital
through the sale of additional stock. You should read "Shares Eligible for
Future Sale" for a full discussion of shares that may be sold in the public
market in the future.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements that involve
substantial risks and uncertainties. You can identify these statements by
forward-looking words such as "may," "will," "expect," "intend," "anticipate,"
"believe," "estimate," "continue" and other similar words. You should read
statements that contain these words carefully because they discuss our future
expectations, make projections of our future results of operations or of our
financial condition or state other "forward-looking" information. We believe
that it is important to communicate our future expectations to our investors.
However, there may be events in the future that we are not able to accurately
predict or control. The factors listed in the sections captioned "Risk Factors"
and "Management's Discussion and Analysis of Financial Condition and Results of
Operations," as well as any cautionary language in this prospectus, provide
examples of risks, uncertainties and events that may cause our actual results to
differ materially from the expectations we describe in our forward-looking
statements. Before you invest in our common stock, you should be aware that the
occurrence of the events described in the "Risk Factors" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
sections and elsewhere in this prospectus could have a material adverse effect
on our business, operating results and financial condition.

                                USE OF PROCEEDS

     We expect to receive net proceeds of approximately $          from the sale
of the           shares of common stock (approximately $          if the
underwriters exercise their over-allotment option in full), at an assumed
initial public offering price of $     per share, after deducting the estimated
underwriting discount and estimated offering expenses.

     Our principal purposes for engaging in this offering are to:

     - increase our equity capital;

     - create a public market for our common stock; and

     - facilitate our future access to public equity markets.

     We expect to use the net proceeds from this offering primarily for working
capital and other general corporate purposes, including expenditures for
research and development and sales and marketing efforts. In addition, we may
use a portion of the net proceeds to acquire businesses, products or
technologies that are complementary to our current or future business and
product lines. We are not currently negotiating any acquisitions, and we have no
agreements with any third party for any acquisition. Pending use of the net
proceeds of this offering, we intend to invest the net proceeds in
interest-bearing, investment-grade securities.

                                DIVIDEND POLICY

     We have never declared or paid any dividends on our capital stock, and we
do not intend to pay cash dividends on our common stock in the foreseeable
future. We currently expect to retain any future earnings to fund the operation
and expansion of our business. In addition, the terms of our credit agreement
prohibit the payment of any dividends.

                                    DILUTION

     Our pro forma net tangible book value at December 31, 1999 was $22.2
million, or $0.67 per share of common stock. Pro forma net tangible book value
per share is determined by dividing our net tangible book value (total tangible
assets less total liabilities) by the pro forma number of shares of common stock
outstanding as of December 31, 1999, after giving effect to the conversion of
all outstanding shares of our preferred stock into 15,128,853 shares of common
stock.

     Dilution in pro forma net tangible book value per share represents the
difference between the amount per share paid by purchasers of shares of common
stock in this offering and the pro forma net tangible book value per share of
common stock immediately after the completion of this offering. After giving
effect to our sale of           shares of common stock in this offering at an
initial public offering price of $     per share and after deducting estimated
underwriting discounts and commissions and estimated offering expenses payable
by us, our adjusted pro forma net tangible book value at December 31, 1999 would
have been $     million, or $     per share. This amount represents an immediate
increase in pro forma net tangible book value to our existing stockholders of
$     per share and an immediate dilution to new investors of $     per share.
The following table illustrates this per share dilution:

     If the underwriters exercise their over-allotment option in full, our
adjusted pro forma net tangible book value at December 31, 1999 would have been
$     million, or $     per share, representing an immediate increase in pro
forma net tangible book value to our existing stockholders of $     per share
and an immediate dilution to new investors of $     per share.

     The following table summarizes, on a pro forma basis as of December 31,
1999, the total number of shares of common stock purchased from us, the total
consideration paid to us and the average price per share paid by existing
stockholders and by new investors purchasing shares of common stock in this
offering. These amounts assume conversion of all outstanding series of preferred
stock into common stock. The information presented is based upon an assumed
initial public offering price of $     per share, before deducting estimated

     This discussion and table assume no exercise of any stock options or
warrants outstanding at December 31, 1999 and no exercise of the underwriters'
over-allotment option. At December 31, 1999, there were options outstanding to
purchase a total of 4,057,498 shares of common stock with a weighted average
exercise price of $0.86 per share. At December 31, 1999, there were warrants
outstanding to purchase a total of 658,693 shares of common stock with a
weighted average exercise price of $0.83 per share. To the extent that any of
these options or warrants are exercised, there will be further dilution to new
investors.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion should be read in conjunction with the financial
statements and related notes that appear elsewhere in this prospectus. The
following discussion contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ significantly from those
anticipated in these forward-looking statements as a result of certain factors,
including those discussed below and elsewhere in this prospectus, particularly
under the heading "Risk Factors."

OVERVIEW

     We are a leading provider of Intelligent Storage Routers and external RAID
controllers for open systems network storage solutions. Our Intelligent Storage
Routers facilitate the interconnection of SANs with existing SCSI-based servers
and storage systems. Our external RAID controllers dynamically distribute data
across multiple hard disk drives to increase data transfer speeds and deliver
fault tolerance. Our products are designed to provide a high level of
performance, availability and functionality.

     Our company was incorporated in January 1998 as Chaparral Technologies,
Inc., a Delaware corporation. We initially focused our operating activities on
the research and development of our Intelligent Storage Routers and on building
our organization by hiring engineering, sales and administrative staff. In July
1999, we changed our name to Chaparral Network Storage, Inc. to more accurately
reflect our emphasis on providing network storage products.

     In November 1998, we entered into a technology license agreement with
Adaptec for their external Fibre Channel RAID controllers in exchange for a
19.9% equity interest in our company. As part of this technology license, we use
Adaptec's hardware platform in our Intelligent Storage Routers and external RAID
controllers. We began shipping our first external RAID controller products, the
G Series, in November 1998. In March 1999, we completed the design of our next
generation external RAID controllers, which served as the basis for developing
our Intelligent Storage Routers. We began shipping our Intelligent Storage
Routers in April 1999. In November 1999, we announced the next generation of
both the external RAID controllers and Intelligent Storage Routers. Through
December 31, 1999, we sold approximately 4,500 units of our Intelligent Storage
Routers and external RAID controllers.

     Since our inception, we have incurred significant losses, and as of
December 31, 1999, we had an accumulated deficit of approximately $8.4 million.
For the nine months ended December 31, 1999, our loss from operations was
approximately $4.4 million. We have not achieved profitability on a quarterly or
annual basis and expect to incur significant losses for the foreseeable future.

     For the nine months ended December 31, 1999, approximately 74% of our
revenue was from the sale of our external RAID controllers and the remaining 26%
of revenue was from the sale of our Intelligent Storage Routers. As we continue
to develop and ship Intelligent Storage Routers, we expect they will constitute
an increasing percentage of our revenue, which in turn may result in a higher
gross margin. Our Intelligent Storage Routers may not gain wide market
acceptance.

     We sell our products to OEMs, distributors, resellers and systems
integrators. Our OEM customers include Eurologic, MicroNet, nStor, Qualstar,
Quantum/ATL, Trimm and Xyratex. During the nine months ended December 31, 1999,
our three largest OEM customers, nStor, Quantum/ATL and Eurologic, accounted for
24.3%, 21.6% and 10.9% of our revenue, respectively. Although we anticipate the
majority of our revenue will come from new and existing OEM customers, a key
element of our growth strategy is to expand and diversify our distribution
channels. To this end, we have established relationships with industrial
distributors, including Arrow, Bell Microproducts and CONSAN, which resell our
products to value added resellers (VARs) and systems integrators. During the
nine months ended December 31, 1999, sales to CONSAN represented approximately
16% of our revenue. No other distribution channel customer accounted for more
than 10% of our revenue in this period.

     We are seeking to diversify our customer base and expand our sales channel.
However, we expect a significant portion of our revenue in the short term will
be derived from a relatively small number of
                                       22
<PAGE>   24

OEMs and distribution channel partners. We may not be successful in diversifying
our customer base, and the loss of one of our significant customers could reduce
our total revenue. We do not have long term contracts with any of our customers.

     We generally recognize product revenue at the time of shipment. Estimated
product returns are accrued in the period of sale. We recognize a warranty
reserve based on a combination of historical experience and specifically
identified potential warranty liabilities, if any. We warrant our products for
up to three years, and we have had no significant warranty issues to date.

     We outsource our manufacturing, which allows us to focus on designing,
developing and marketing our products. We believe the use of a high quality
contract manufacturer, which has multiple manufacturing locations, allows us to
deploy our resources and capital more efficiently. A significant portion of our
cost of sales consists of payments for contract manufacturing. A less
significant amount is spent on components, which we consign to our
manufacturers, and for royalties on licensed technology. Our contract
manufacturers build our products using quality assurance programs and standards
that we establish and monitor. Manufacturing engineering as well as
documentation control are conducted at our facility in Longmont, Colorado.

RESULTS OF OPERATIONS

     Because of our limited operating history and the rapidly evolving nature of
our business, we believe that period-to-period comparisons are not meaningful
and should not be relied upon as an indication of future performance. The
following table presents our operating results for our fiscal year ended March
31, 1999, and the nine-month periods ended December 31, 1998 and December 31,
1999.

</TABLE>

  NINE MONTHS ENDED DECEMBER 31, 1999 COMPARED TO NINE MONTHS ENDED DECEMBER 31,
  1998

     Revenue

     Revenue was $6.3 million for the nine months ended December 31, 1999,
compared to $143,000 for the comparable period in 1998. We commenced product
sales in the quarter ended December 31, 1998. For the nine months ended December
31, 1999, sales of our Intelligent Storage Routers constituted $1.6 million, or
26% of our revenue, while for the comparable period in 1998, sales of our
external RAID controllers constituted all of our revenue. For the nine months
ended December 31, 1999, 26 customers accounted for all of our revenue, compared
to three customers in the comparable period in 1998.

                                       23
<PAGE>   25

     Gross Profit

     Cost of sales includes the cost of our contract manufacturing, materials
costs, warranty costs, manufacturing overhead, royalties and a reserve for
inventory obsolescence.

     Gross profit increased to $3.4 million for the nine months ended December
31, 1999, from $104,000 for the comparable period in 1998. Gross profit as a
percentage of revenue was 54% for the nine months ended December 31, 1999. Due
to the small amount of revenue for the nine months ended December 31, 1998, we
do not believe that a period-to-period comparison of gross profit is meaningful.

     Research and Development

     Research and development expense consists primarily of salaries and related
personnel costs, fees paid to consultants and outside service providers,
non-recurring engineering charges and prototype costs related to the design,
development, testing and enhancement of our products and software and systems
development. We expense our research and development costs as they are incurred.

     Research and development expense was $2.5 million for the nine months ended
December 31, 1999, an increase of $1.8 million over the comparable period in
1998. This increase was due primarily to costs associated with the addition of
research and development personnel and increased prototype expenses, which
included equipment, supplies and outside consultants. Research and development
personnel increased to 31 at December 31, 1999, from 19 at December 31, 1998. We
believe that strategic product development and other research and development
initiatives are required to remain competitive. As a result, we expect our
research and development expense to increase in absolute dollars in the future.

     Sales and Marketing

     Sales and marketing expense consists primarily of salaries, commissions and
related expenses for personnel engaged in marketing, sales and customer
engineering support functions, as well as costs associated with promotional and
other marketing expenses.

     Sales and marketing expense was $1.5 million for the nine months ended
December 31, 1999, an increase of $1.3 million over the comparable period in
1998. The increase was primarily due to the costs associated with the addition
of sales and marketing personnel as well as trade show and advertising expenses.
Sales and marketing personnel increased to 14 at December 31, 1999, from three
at December 31, 1998. We expect sales and marketing expense will increase
substantially in absolute dollars over the next year, as we hire additional
sales and marketing personnel, expand our customer service and support
organization, initiate additional marketing programs and establish sales offices
in new domestic and international locations.

     General and Administrative

     General and administrative expense consists primarily of salaries and
related expenses for executive, finance and accounting, facilities and human
resources personnel, recruiting expenses, professional fees, reserves for
doubtful accounts and other corporate expenses.

     General and administrative expense increased by $1.0 million to $2.2
million for the nine months ended December 31, 1999, from $1.2 million for the
comparable period in 1998. This increase was due primarily to costs associated
with the addition of general and administrative personnel, increased
professional and consulting activities and a provision for doubtful accounts.
General and administrative personnel increased to ten at December 31, 1999, from
six at December 31, 1998. We expect general and administrative expense to
increase in absolute dollars as we add personnel and incur additional costs
related to the growth of our business and our operation as a public company.

                                       24
<PAGE>   26

     Stock Option Compensation

     We recognized stock option compensation expense of $1.6 million in the nine
months ended December 31, 1999. Of this amount, $818,035, $58,279 and $743,791
relate to research and development, sales and marketing and general and
administrative expenses, respectively. Unearned stock option compensation
expense of $0.7 million will be recognized over the vesting periods of the
associated stock options.

     Interest Expense, Net

     We had net interest expense of $284,000 for the nine months ended December
31, 1999, as a result of interest paid for financing fees and for debt
outstanding during the period which was repaid as of December 31, 1999. We had
no interest expense for the nine months ended December 31, 1998.

     Provision for Income Taxes

     There is no provision for income taxes, as we have incurred losses for all
periods to date. As of March 31, 1999, we had approximately $3.6 million of U.S.
federal and state net operating loss carryforwards available to offset future
taxable income. Net operating loss carryforwards will expire in 2019 to the
extent that they are not utilized. We believe the carryforwards may also be
limited by Internal Revenue Code provisions.

  FISCAL YEAR ENDED MARCH 31, 1999 COMPARED TO THE PERIOD FROM INCEPTION TO
  MARCH 31, 1998

     We had no revenue during the first three months of operations and incurred
only $35,000 of general and administrative expense during this period. For this
reason, it is not meaningful to compare results between the fiscal year ended
March 31, 1999, and the period from inception to March 31, 1998.

QUARTERLY RESULTS OF OPERATIONS

     The following table presents historical unaudited quarterly information for
our most recent five quarters. All quarters have been prepared on the same basis
as the audited financial statements appearing elsewhere in this prospectus. In
the opinion of management, all necessary adjustments consisting only of normal
recurring adjustments have been included to present fairly the unaudited
quarterly results when

     Revenue decreased between the third and fourth calendar quarters of 1999 by
$870,000. Revenue decreased primarily because our customer nStor returned
approximately $400,000 of our external RAID controllers following an order
cancellation by one of its customers. Although we had shipped this product to
nStor in the quarter ended December 31, 1999, pursuant to a noncancellable
purchase order, we chose not to recognize this revenue. We have not waived any
claims arising from nStor's cancellation of this order. Also, due to this
cancellation, we did not ship additional product pursuant to other nStor
noncancellable purchase orders for approximately $547,000. For the quarter ended
September 30, 1999, nStor accounted for $1.2 million of our revenue. Primarily
as a result of the cancellation of this order and our decision not to ship
additional products to nStor, our revenue for the quarter ended December 31,
1999 decreased approximately 28% from the previous quarter. We are not currently
shipping to nStor, have received no new purchase orders from nStor and may not
ship to them in the future.

     Since the introduction of our Intelligent Storage Routers in April 1999,
our gross profit as a percentage of revenue has increased as a result of the
higher margins earned by these products.

     We had net interest expense for the fourth calendar quarter of 1999 as a
result of interest paid for financings fees and for debt outstanding during the
period which was repaid as of December 31, 1999.

     Our revenue, gross profit and operating results may vary significantly from
quarter to quarter due to a number of factors, many of which are outside of our
control, including those specifically discussed in the

                                       26
<PAGE>   28

section captioned "Risk Factors." The primary factors that may cause our
quarterly revenue and operating results to fluctuate include the following:

     - fluctuations in demand for our Intelligent Storage Routers and external
       RAID controllers;

     - the size, timing, terms and fluctuations of customer orders and product
       implementations;

     - the rate of adoption of SANs as an alternative to existing
       server-attached storage architectures;

     - the mix of our Intelligent Storage Routers and external RAID controllers
       sold;

     - the mix of distribution channels through which our products are sold;

     - new product introductions by us or our competitors;

     - deferrals of customer orders in anticipation of new products, services or
       product enhancements introduced by us, our OEMs, our competitors or from
       other providers of SAN products;

     - changes in our pricing policies or the pricing policies of our
       competitors;

     - our ability to develop, introduce, ship and support new products and
       product enhancements that meet customer requirements in a timely manner;

     - prototype expenses;

     - our ability to obtain sufficient supplies of components, including sole
       or limited source components;

     - increases in the prices of the components we purchase;

     - our ability to attain and maintain production volumes and quality levels;

     - the ability of our contract manufacturers to produce and distribute our
       products in a timely fashion;

     - the software enhancements embedded in our hardware platforms;

     - the additional software options incorporated in our products; and

     - general economic conditions as well as those specific to the SAN and
       related industries.

     Our operating expense is largely based on anticipated revenue trends. A
high percentage of our expenses are and will continue to be fixed in the short
term. As a result, a delay in generating or recognizing revenue for these
reasons could cause significant variations in our operating results from quarter
to quarter.

     We expect to experience seasonality in our operating results. Our results
of operations may be adversely affected in the third calendar quarter due to a
slowdown of sales in Europe and other foreign areas in the summer months. We
also expect that, generally in the first calendar quarter, our results may be
adversely affected due to our customers' budgeting cycles.

LIQUIDITY AND CAPITAL RESOURCES

     Since inception, we have financed our operations primarily through the sale
of common and preferred stock, generating aggregate proceeds of $29.0 million,
net of issuance costs. For the nine months ended December 31, 1999, cash flows
from financing activities were $24.6 million. In the past, we also have financed
a portion of our operations through loans from a bank and from individuals. We
currently have no debt outstanding.

     We used $4.9 million in cash for operations during the nine months ended
December 31, 1999, an increase of $3.2 million over the comparable period in
1998. This increase was primarily due to increases in our net loss, increases in
trade receivables and inventory, partially offset by increases in accounts
payable and accrued liabilities.

                                       27
<PAGE>   29

     For the nine months ended December 31, 1999, cash flows from investing
activities consisted of $336,000 for capital expenditures. Cash flows from
investing activities for the comparable period in 1998 totaled $395,000,
including the non-cash acquisition of equipment from Adaptec.

     In July 1999, we obtained a $3.0 million line of credit from a bank,
secured by our accounts receivable and other collateral, at a variable rate
equal to the bank's prime rate plus 1.5% per annum. During the nine months ended
December 31, 1999, the maximum outstanding balance on this line was $750,000. As
of December 31, 1999, there was no outstanding balance. This line of credit was
terminated and replaced in January 2000.

     In January 2000, we entered into a loan agreement with Norwest Bank
Colorado N.A.-Boulder. Under the loan agreement, we can borrow and reborrow up
to the lesser of $3.0 million or an amount equal to 90% of our U.S. issued debt
instruments plus 80% of our investment grade commercial paper, with a maturity
of one year or less and held in a Norwest account and pledged to Norwest.
Borrowings bear interest at Norwest's prime rate. Interest is payable monthly in
arrears on the last day of the month, and borrowings must be repaid on or before
August 31, 2000. Under the loan agreement, we have agreed to provide Norwest
with certain financial information about our business, to maintain at least $4.0
million in cash plus investment grade marketable securities, to maintain a
minimum net worth and minimum ratio of debt to net worth as set forth in the
agreement and to use Norwest as our principal depository for demand and savings
business accounts. We also have agreed not to pay dividends on our stock, create
liens on our properties or borrow under other credit arrangements. We have not
borrowed under this loan agreement.

     At December 31, 1999, cash and cash equivalents totaled $19.7 million. Our
capital requirements depend on numerous factors, including:

     - market acceptance of our products;

     - the resources we devote to developing, marketing, selling and supporting
       our products;

     - the timing and extent of establishing international operations; and

     - the timing and build-out of our new facility and related interoperability
       testing lab.

     We expect to devote substantial capital resources to continue our research
and development efforts, to hire and expand our sales, support, marketing and
product development organizations, to expand marketing programs, to establish
additional facilities and for other general corporate activities. We believe the
net proceeds of this offering, together with our cash and cash equivalents, will
be sufficient to fund our operations through at least the next 12 months.
However, there can be no assurance that we will not require additional financing
within this time period or that such additional funding, if needed, will be
available on terms acceptable to us or at all.

INDUSTRY BACKGROUND

  GROWTH AND CHANGING NATURE OF ENTERPRISE DATA

     In the last decade, there has been a dramatic increase in the volume of
data created, processed and accessed throughout the business enterprise.
According to International Data Corporation (IDC), an independent industry
research company, shipments of multi-user disk storage capacity grew from
approximately 10,000 terabytes in 1994 to approximately 184,641 terabytes in
1999 and is forecasted to reach approximately 1.9 million terabytes in 2003. The
near annual doubling of growth in the volume of enterprise data storage needs
has been fueled by a number of factors, including:

     - the increase of Internet and e-commerce based businesses;

     - the rapid growth of Web hosting, digital video and other multimedia
       applications;

     - the rise of network computing;

     - the need for redundant repositories of data; and

     - advances in storage technology and the resulting decline in the cost of
       storage.

     In addition, organizations have recognized the increasing importance and
value of enterprise data as mission-critical and as a strategic and competitive
asset to their employees, customers and suppliers. These organizations are
demanding rapid and reliable access to this data 24 hours a day, seven days a
week. The increased use of open-systems computing environments, which link
multiple applications, files and databases to networked computers, makes this
task increasingly difficult. The continued deployment of mission-critical,
client-server applications, coupled with the growth of enterprise data, has
placed significant strain on current storage architectures.

LIMITATIONS OF EXISTING STORAGE INFRASTRUCTURE

     The growth of enterprise data has resulted in a corresponding challenge to
backup, share and manage this data. This growth has traditionally been addressed
by connecting individual high-performance computers, known as servers, to
dedicated storage devices. Typically, storage devices are connected through SCSI
technology to only one server and not to any of the other servers used by an
enterprise which results in a "captive" storage architecture.

                                       29
<PAGE>   31

     The captive storage architecture can be depicted as follows:

    [Graphic depicting the captive storage architecture, including the SCSI
  connections between storage devices and servers and the connections between
          servers and network end-users through a Local Area Network.]

     Traditional captive storage architectures have several significant
limitations, including:

  PERFORMANCE CONSTRAINTS

     Data storage, retrieval and backup using the traditional captive storage
architecture results in a significant strain on servers and local area networks,
or LANs. Storage-to-server data transmission speeds increased by approximately
ten times in the 1990s when local and wide-area network transmission speeds
increased by more than 100 times. In captive storage architectures, client data
is transferred across the LAN to servers and their dedicated storage devices,
causing an I/O bottleneck. Because LANs were not designed to efficiently
transfer data in large blocks, data backup has been a major contributor to
performance constraints.

  LIMITED AVAILABILITY AND ACCESSIBILITY OF DATA

     In traditional server-attached architectures, the loss of a server causes
data on its connected storage devices to become inaccessible. In addition, the
critical data backup function in the traditional server-attached storage
architecture is a lengthy process and often requires the network to be powered
down. Because many networks need to be accessible 24 hours a day, seven days a
week, the time available to accomplish data backup has been reduced considerably
or eliminated entirely, while the amount of data requiring backup has increased
dramatically.

  LIMITED FAULT AND DISASTER TOLERANCE

     Because SCSI-connected devices are limited to a maximum of 25 meters of
transmission distance, redundant storage devices in remote locations are
generally not practical or cost effective. As a result, sustained data
availability in a captive storage architecture following a system failure or
disaster is difficult to achieve.

  SCALABILITY CONSTRAINTS

     The SCSI protocol can only support a maximum of 15 individual storage
devices on a single bus or channel, which is the dedicated circuit that carries
information to and from data storage devices. Because servers have limited space
for additional SCSI adapter cards, businesses that wish to add storage capacity

                                       30
<PAGE>   32

generally must add additional servers, increasing the total cost of storing
data. Additionally, the distance limitation of the SCSI protocol constrains the
amount of storage that can be attached to a single server.

  LACK OF MANAGEABILITY

     The traditional server-attached storage architecture has made it difficult
to network storage devices and realize the benefits of managing a centralized
data repository. As a result, isolated islands of information are stored
throughout the enterprise, each of which must be administered and managed
locally.

DEVELOPMENT OF STORAGE AREA NETWORKS BASED ON FIBRE CHANNEL TECHNOLOGY

     In recent years, demand has increased for a faster, more efficient and
manageable interconnection of servers, storage devices and LANs. SANs are
rapidly gaining acceptance as a means of addressing this demand through the
support of a transmission protocol known as Fibre Channel. Fibre Channel is an
open standard technology designed specifically for high performance, I/O
intensive applications, with the ability to attach storage in shared network
environments. Fibre Channel is capable of supporting up to 15.5 million devices
and transferring data across distances of ten kilometers at speeds of up to 200
megabytes per second. Similar to LANs and wide area networks, or WANs, the SAN
applies the networked approach to computer storage and servers, enabling
businesses to create a pool of shared data storage devices that can be accessed
by multiple servers and network users.

     The following graphic depicts a basic SAN architecture.

  [Graphic depicting a basic SAN arcitecture, including the major SAN network
elements, such as Switches, Routers and Hubs, the Servers, and the various types
           of storage devices, such as disk arrays and tape systems.]

     SANs offer the following benefits:

     - improved performance by decreasing storage traffic on the LAN and
       increasing the speed of a dedicated network for storage;

     - higher accessibility and availability of data through any-to-any
       connectivity, which creates redundancies and improves fault-tolerance;

     - greater scalability by significantly increasing the distance between and
       number of devices that can be connected;

     - ease of management facilitated by the networked architecture and
       centralization of storage; and

     - lower cost of ownership from improved efficiencies, reduced management
       requirements and shared storage resources.

                                       31
<PAGE>   33

     While in its early stages of development, the open systems SAN market is
expected to grow rapidly. According to the Gartner Group, an independent
industry research company, more than 70% of shared storage in network
environments is projected to be reorganized into SANs by the year 2002. IDC has
estimated that worldwide SAN storage systems revenues will grow from less than
$3.8 billion in 1999 to over $11.5 billion in 2002, representing a compound
annual growth rate of 45%.

OPEN SYSTEMS SAN EVOLUTION

     To date, SANs have been deployed in an evolutionary fashion. Initial SAN
implementations of Fibre Channel devices focused simply on connectivity and
interoperability of devices, including hubs, switches and host bus adapters.
Because most organizations had made significant investments in SCSI storage
devices and servers, companies were unwilling to move to SANs unless they were
able to connect to these devices. Products such as storage routers were
introduced to provide this connectivity between SCSI storage devices and Fibre
Channel SANs. Additionally, because Fibre Channel storage devices are
network-attached in SANs, vendors needed to ensure interoperability among these
devices. As a result, vendors originally focused on providing connectivity
between SCSI and Fibre Channel protocols and ensuring interoperability.

     While SANs are being successfully implemented and connectivity and
interoperability issues are being addressed, many of the benefits offered by the
SAN, including enhanced data transfer rates, improved reliability and
accessibility and more robust features, have yet to be fully realized. Because
data will now be shared by and accessible to multiple servers and networked
users, enterprises will require not only high performance but also high
availability of mission-critical data. For widespread adoption of SANs to occur,
these requirements must be addressed.

THE CHAPARRAL SOLUTION

     We have developed Fibre Channel-based SAN solutions that provide both high
performance and high availability. We are the only independent provider of both
storage routers and external RAID controllers. Our Fibre Channel-to-SCSI routers
and external RAID controllers enable organizations to realize the full benefits
of Fibre Channel SANs, such as increased bandwidth performance, improved
scalability and centralized storage management efficiencies, while preserving
their investments in new and existing SCSI storage devices. This is a key
requirement because organizations have already made, and are expected to
continue to make, significant investments in SCSI-based servers and storage
systems. IDC estimates that SCSI is currently the most popular interconnect for
high-performance disk drives, representing more than 90% of units in 1999, and
will still represent approximately two-thirds of units in 2002.

     Key benefits of our solutions include the following:

  INCREASED PERFORMANCE

     We believe our products provide industry-leading performance and
functionality to facilitate the interconnection of SANs and SCSI-based storage
devices. Both our Intelligent Storage Routers and external RAID controllers are
designed using our architecture, which includes embedded software and a high
speed ASIC. This ASIC has a dual internal data path that is completely
independent of the computer processor. This ASIC also enables our products to
move data at high speeds and with minimal interruption between the Fibre Channel
connections to the servers and the SCSI connections to the storage devices. As a
result, we are able to deliver market-leading I/O performance.

  HIGH AVAILABILITY AND RELIABILITY

     We believe that our products provide the highest level of availability and
reliability. Our external RAID controllers dynamically distribute data across
multiple hard disk drives with a special error correction and detection
algorithm designed to ensure the immediate availability of data, even in the
event of a partial or complete disk drive failure. Our external RAID controllers
also utilize sophisticated algorithms to recreate lost data in any one disk
drive. In addition, our external RAID controllers provide an active-active
failover capability. This feature enables two external RAID controllers to be
actively
                                       32
<PAGE>   34

working in tandem because they are connected to the disk drives as well as to
each other. In the event one of these external RAID controllers fails, the other
external RAID controller takes over the entire workload, maintaining
accessibility to the stored data. Because two active external RAID controllers
share the workload of distributing and accessing data on the disk drives,
throughput is effectively doubled. This active-active failover capability
permits higher availability of data and protects the enterprise against both
disk drive and controller failure and the resulting inaccessibility and
potential loss of mission-critical data.

     We have leveraged our external RAID controller expertise to develop what we
believe will be the industry's first and only active-active failover
functionality for storage routers. We are currently in Beta evaluation with OEM
customers for storage routers with this functionality. We believe this
functionality will be a key differentiator and a mandatory requirement for the
effective implementation and widespread deployment of SANs for mission-critical
applications. In addition, our Intelligent Storage Routers incorporate our
real-time operating system. This operating system has been designed to provide
both high performance and high availability, which we believe will be required
for the next wave of SAN implementations.

     We have incorporated diagnostics and monitoring software into both our
Intelligent Storage Routers and our external RAID controllers to provide early
warning and failure notification, as well as the ability to remotely monitor and
manage these controllers.

  IMPROVED SAN PERFORMANCE WITH NEW APPLICATIONS

     Because we have designed our products using a highly flexible and modular
embedded software architecture, we can quickly and cost-effectively implement
new software agents that enable SAN applications such as server-free backup.
Server-free backup enables automated data movement between storage systems
directly across the SAN, allowing data backup to be performed while using a very
small percentage of the server's internal data processing capacity. As a result,
organizations no longer need to identify lengthy time periods, or "backup
windows," for disconnecting servers from the network in order to perform backup.

     We were the first company to successfully publicly demonstrate server-free
backup. Our Intelligent Storage Routers enable server-free backup in connection
with software anticipated to be released by Legato and other companies in the
near future. Although our competitors have recently developed this capability,
we believe the higher speeds with which our products operate will provide us
with a competitive advantage in the market for server-free backup.

  DIFFERENTIATION AND MANAGEABILITY

     We have developed a robust, well-defined user interface, which we call
CAPI, to enable our customers to incorporate their proprietary functionality
into our products for differentiation in the market. In addition, our customers
can design their own GUI to manage our equipment in conjunction with their
solutions.

     We also work closely with leading independent software vendors, such as
Legato Systems, Inc., Veritas Software Corporation and Computer Associates
International, Inc., to help ensure that our Intelligent Storage Routers can be
managed through their network management software applications. Our Intelligent
Storage Routers are also designed with features that enable organizations to
conduct systems diagnostics and management, as well as real-time application
monitoring, from remote locations.

STRATEGY

  LEVERAGE COMMON HARDWARE AND SOFTWARE ARCHITECTURE

     Our Intelligent Storage Routers and external RAID controllers share a
common hardware and embedded software architecture. We intend to continue to use
this common architecture to quickly and cost-effectively introduce
next-generation products into the market. We utilize a modular hardware
architecture that includes a separate snap-on card, called a daughter card, for
the Fibre Channel interface.

                                       33
<PAGE>   35

We believe this daughter card will allow us to introduce higher performance,
next-generation products without changing the basic architecture of our hardware
platforms. For example, when two gigabit Fibre Channel integrated circuits
become commercially available, we believe we will be able to quickly introduce
new products with the improved transfer rates that these chips provide without
redesigning the entire hardware platform. We expect our daughter card
architecture will give us a time-to-market competitive advantage, reduce our
development costs and allow us to leverage our interoperability with existing
products.

     We plan to leverage our common embedded software architecture to introduce
the server-free backup capability into our external RAID controllers for fast
disk-to-disk copy capability. We also intend to leverage our modular embedded
software architecture to facilitate the development of future SAN applications,
such as data replication, non-stop unattended backup and continuous remote
mirroring.

  ACTIVELY PURSUE NEW STRATEGIC ALLIANCES TO ENABLE NEW APPLICATIONS

     We plan to partner with leading independent software vendors to integrate
value-added functionality into our products to meet the evolving needs of our
customers. By incorporating embedded software agents into our products, we
expect to rapidly expand the capabilities we are able to offer and, in doing so,
increase the market for our solutions. For example, we were the first to have
the capability to incorporate an Extended Copy embedded software agent into our
Intelligent Storage Routers. By incorporating this software agent, we were able
to extend the functionality of our Intelligent Storage Routers to enable
server-free backup. We publicly demonstrated server-free backup with Legato and
Quantum/ATL at the Networld/Interop trade show in May 1999 and expect to ship
products with this function in connection with software anticipated to be
released by Legato and other companies in the near future.

     As the SAN market evolves, we intend to work with leading independent
software vendors to jointly define embedded software agents that integrate
management functionality into our products. By establishing strategic
relationships with independent software vendors, we believe we will be able to
significantly increase the value of our product offerings and ensure a product
migration path in line with the needs of our customers.

  DRIVE EMERGING I/O MARKET OPPORTUNITIES

     We plan to leverage our significant technological expertise in storage
routing to drive emerging I/O market opportunities. As part of these efforts, we
are currently working on the development of an Intelligent Storage Router that
would extend the capabilities of the SAN over the WAN. While Fibre Channel SANs
can currently transfer data over distances of up to ten kilometers, we can
provide access to storage devices over virtually unlimited distances by bridging
Fibre Channel with WAN protocols, such as asynchronous transfer mode, or ATM. We
also are focusing our development efforts on a number of other emerging I/O
technologies including Peripheral Control Interface-X (PCI-X), Transfer Control
Protocol/ Internet Protocol (TCP/IP) and gigabit Ethernet, as well as future I/O
technologies, such as the InfiniBand protocol. We will continue to contribute to
the development of these and other I/O interfaces as these technologies gain
market acceptance. We believe that this participation will help us to define
improved ways of building intelligent I/O interconnections, influence relevant
standards, quickly implement and deliver products to OEMs and other customers.

  EXPAND RELATIONSHIPS WITH OEMS

     We intend to continue to focus on developing relationships with OEMs. We
believe that working with OEMs enables us to effectively distribute our
products, anticipate the needs of the market, introduce new products to meet
those needs and target new markets. We intend to continue to offer high-value,
easily integrated products that can be quickly brought to market. We believe
that these products will help us expand our OEM customer base. For example, the
small size of our controller board is attractive to OEMs because they can easily
integrate it internally into their tape libraries and subsystem products.
Additionally,

                                       34
<PAGE>   36

we plan to enhance our CAPI functionality to incorporate new SAN applications
that will be attractive to OEMs.

     As new disk and tape technologies with significantly higher transfer rates
emerge, we intend to leverage the high performance features of our Intelligent
Storage Routers and external RAID controllers to take advantage of each new OEM
qualification and sourcing cycle. We believe our technology will enable us to
continue to capture OEMs that require high performance and high availability in
their storage solutions.

  EXPAND DISTRIBUTION CHANNELS

     While sales to our OEM customers have accounted for the majority of our
revenue, we believe that our success depends in part on the successful creation
of an open systems market channel through both subsystem vendors and
distributors. We have established relationships with several distributors,
including Arrow, Bell Microproducts and CONSAN in the United States, and CPI,
Hammer Distributing, Infodip and United Digital in Europe. We intend to enter
into additional agreements, both domestically and internationally, to increase
our geographic coverage and address new markets. We also intend to develop
relationships with key SAN systems integrators. We expect that sales through
these distribution channels will constitute an increasing portion of our total
sales in the future.

  WORK CLOSELY WITH STRATEGIC PARTNERS AND INDUSTRY ALLIANCES TO FACILITATE
  WIDESPREAD ADOPTION OF SANS

     We intend to continue working closely with leaders in the storage,
networking and computing industries to develop new and enhanced SAN products. We
believe that establishing strategic relationships with technology partners is
essential in facilitating the efficient and reliable integration of their
capabilities into our SAN solutions. We are developing strategic relationships
and industry alliances with leading technology companies, including the
following:

PRODUCTS

     We currently offer two product lines: Intelligent Storage Routers and
external RAID controllers. Our products are designed to provide high-performance
data storage and Fibre Channel SAN solutions in an open systems computing
environment. These products share a common hardware and embedded software
architecture. Our embedded software agents are also offered separately as
optional features for each of our products.

  INTELLIGENT STORAGE ROUTERS

     Our Intelligent Storage Routers enable seamless bi-directional connectivity
between SCSI devices and Fibre Channel networks, allowing companies to take
advantage of the benefits of Fibre Channel technology while protecting their
investment in new and legacy SCSI storage devices. Our Intelligent Storage
Routers utilize our external RAID controller platform but are configured with
different embedded software for SCSI peripherals including tape drives,
automated robotic tape libraries and optical storage devices. Our Intelligent
Storage Routers meet the performance and availability requirements of both
departmental and enterprise server needs as well as advanced applications for
SANs. Our Intelligent Storage Routers also have the ability to offer high-speed
backup over Fibre Channel in connection with software anticipated to be released
by Legato and other companies in the near future. Server-free backup allows
users to perform backup operations directly from disk to tape without first
copying data to the host computer. Server-free backup accelerates the backup
operation as well as off-loading the operations from the LAN and host computer.

     F Series. Our F Series of Intelligent Storage Routers is an integral
component of our SAN solutions and are critical to enabling organizations to
attain the benefits of these solutions within their existing computer network
infrastructures. We believe these products offer the highest performance
available in the market today. These products are available as an individual
board or in an enclosed 1.7-inch high rack. All of these products also offer the
optional Celestra Extended Copy embedded software agent to provide server-free
backup. In November 1999, we announced our third generation products (FS2420x).
These products incorporate a dual-loop Fibre Channel interface as well as the
industry's first Ultra 3 SCSI with 160 megabyte per second performance per
channel, providing both higher availability and higher performance.

  EXTERNAL RAID CONTROLLERS

     Our external RAID controllers offer many fault-tolerance features for
mission-critical computing, such as high performance, redundancy, security and
protection. These products target the external storage business in the open
systems server market as well as the SAN marketplace.

     G Series. Our G Series of products consists of external RAID controller
boards that are typically sold to OEMs for integration into their external
storage subsystems. The first generation of these products targeted
department-level users and feature performance that is rated at either 55
megabytes per second for image-intensive applications or 5,000 I/Os per second
for transaction processing and database applications. In November 1999, we
announced our third generation of external RAID controllers, which feature two
Fibre Channel ports and four Ultra 3 SCSI 160 megabyte per second storage device
channels.

     The third generation products feature performance that is rated at either
180 megabytes per second or 15,000 I/Os per second. These RAID controllers offer
the active-active failover feature for maximum availability.

     K Series. Our K Series of products uses our second generation external RAID
controller board and features a higher level of integration, including battery,
control panel and SCSI cable-ready connectors. Our second generation external
RAID controllers feature performance that is rated at either 90 megabytes per
second or 8,500 I/Os per second. Unlike our G Series, which is designed at the
board level, our K Series is designed into a canister the size of a typical
CD-ROM and fits into a standard 5.25-inch device bay. We sell our K Series
primarily through our distributors to VARs, who desire an integrated product
that can be readily incorporated into a subsystem solution.

     In addition, both series of our RAID controllers include an on-line
expansion capability that allows capacity to be added without taking the
external RAID controller off-line for reconfiguration. Our external RAID
controllers are operating system independent and can be deployed without having
to purchase additional software drivers.

  EMBEDDED SOFTWARE

     In 2000, we expect to ship our embedded software products as
separately-priced, value-added features for both our Intelligent Storage Routers
and external RAID controllers. These products can be provided electronically so
that installed Intelligent Storage Routers and external RAID controllers can be
remotely upgraded at the customer's site. Our embedded software agent is
anticipated to provide server-free backup capability in connection with Legato's
Celestra Networker backup software. We plan to implement this as an optional
feature for our external RAID controllers in the second half of 2000.

     In addition, we have developed embedded software that permits our customers
to prevent access to selected storage devices on a server-by-server basis. This
feature provides greater data security by restricting access to shared data on
the SAN only to authorized users. We expect to offer this as an optional feature
for our Intelligent Storage Routers in the first half of 2000.

CUSTOMERS

     We sell our products to OEMs and distribution channel partners.

  OEM CUSTOMERS

     Our OEM customers accounted for 75.4% of our revenue for the nine months
ended December 31, 1999 and included Eurologics, MicroNet, nStor, Qualstar,
Quantum/ATL, Trimm, and Xyratex.

     For the nine months ended December 31, 1999, our three largest OEM
customers were nStor, Quantum/ATL Products and Eurologics, which accounted for
24.3%, 21.6% and 10.9% of revenue, respectively. We believe we can expand our
current base of OEM customers by offering high-performance, easily integrated
products that can be quickly brought to market.

  DISTRIBUTION CHANNEL PARTNERS

     Our distribution channel partners accounted for the remaining 24.6% of our
revenue during the nine months ended December 31, 1999. These partners are
comprised of distributors and resellers. Our current distribution channel
partners include Arrow, Bell Microproducts and CONSAN.

     During the nine months ended December 31, 1999, CONSAN represented 16.1% of
our revenue. No other distribution channel partner represented more than 10% of
our revenue. We are currently directing significant marketing and development
efforts towards educating and expanding our network of distribution channel
partners.

SALES AND MARKETING

     Our sales and marketing strategy focuses on an indirect sales model
executed through OEMs, distributors, resellers and systems integrators. We have
focused primarily on developing OEM relationships with storage subsystem
suppliers, tape library manufacturers and computer system manufacturers. We
believe the strong market position of these customers will shorten our sales
cycle and further increase sales productivity. Our experienced OEM sales
professionals are supported by application engineers who work in conjunction
with the OEM's engineering team during the qualification process.

     We have established relationships with three industrial distributors in the
United States: Arrow, Bell Microproducts and CONSAN. We have also established
relationships with industrial distributors in Europe, including CPI, Hammer
Distributing, Infodip and United Digital. Industrial distributors resell our
products with other complementary products, such as Fibre Channel switches or
hubs to VARs. This channel is serviced by our regional distribution sales
representatives and inside sales representatives, who provide training and sales
support to distributors. We plan to add additional distributors, including
commercial distributors, that will bundle our products with their storage and
server solutions.

                                       40
<PAGE>   42

     We are in the process of expanding our international sales channels. We
have established relationships with distributors in England, France and Germany.
In the future, we intend to expand our sales efforts to Asia, Australia and
South America.

     Our marketing efforts focus on product marketing, marketing communications,
business development and partnership marketing. We have dedicated significant
marketing efforts towards:

     - establishing relationships with OEMs, distributors, resellers and systems
       integrators;

     - participating in trade shows to promote and launch our products; and

     - identifying new business opportunities.

     Our initial partnership marketing efforts have focused on cooperative
marketing with complementary vendors in the markets for tape backup software and
Fibre Channel switches and hubs. In order to support and develop opportunities
for our indirect distribution channels, we plan to expand our field sales and
support staff significantly.

     We have developed the Chaparral Partners Program to ensure that our
solutions are interoperable with products from multiple vendors. We are working
to provide certified SAN solutions for key systems integrators to offer to their
customers. We believe this program is important both for reference purposes and
to accelerate the acceptance of SANs. We have established a relationship with
Legato to introduce the server-free backup Celestra application worldwide. To
further support our marketing efforts, we intend to establish relationships with
key partners to provide vertical market applications.

CUSTOMER SERVICE AND SUPPORT

     We believe that a broad range of support services is essential to the
successful installation and ongoing support of our Intelligent Storage Routers
and external RAID controllers. Our support engineers have a broad range of
storage and networking experience. Our customer service and support organization
provides comprehensive training programs and telephone, e-mail and Web-based
direct post sales support to our OEM and distributor customers. We believe these
programs allow us to minimize the need for a large end-user support organization
by enabling our OEM and distributor customers to provide installation, service
and primary technical support to their customers, while we focus on high-level
secondary support. In the future, we intend to significantly expand our
pre-sales and post-sales service and support efforts as well as pursue
opportunities to partner with third party support organizations.

TECHNOLOGY

     We develop and market Intelligent Storage Routers and external RAID
controllers. These products combine a number of hardware and software
technologies. Our primary areas of expertise include embedded software and
platform architecture.

     Embedded software. Our Intelligent Storage Routers and external RAID
controllers contain a significant amount of common software. Our embedded
software is designed to enable the high speed capabilities of the ASICs we
license from Adaptec. We utilize the C++ programming language, a highly modular
software architecture, which allows us to use and reuse many of our software
elements in both our Intelligent Storage Routers and external RAID controllers.
Our embedded software provides the following:

     - a real-time operating system, or RTOS, specifically designed for high
       performance;

     - data caching and buffering functionality, I/O drivers, configuration
       utilities and system monitoring;

     - an embedded multiplex user interface, or MUI, which provides a
       feature-rich management tool that is accessible either in-band over the
       SCSI/Fibre Channel ports or out-of-band via a serial port;

     - a CAPI, which enables our customers to implement GUI applications for
       management, configuration and monitoring purposes; and

                                       41
<PAGE>   43

     - the ability to add new features such as active-active failover.

     Platform Architecture. Our products are small form-factor, high performance
"single-board computers" that perform specialized functions such as data routing
or RAID operations. We have developed a proprietary architecture that addresses
important customer requirements, such as:

     - high performance, both in terms of sustained throughput and I/Os per
       second;

     - multiple I/O channels;

     - high reliability;

     - small physical size;

     - configuration flexibility;

     - low power dissipation;

     - manageability; and

     - cost effectiveness.

     Our designs incorporate custom ASICs and dual internal data buses, greatly
increasing data processing speed and throughput capability. Our platform
architecture includes a separate snap-on card, called a daughter card, for the
Fibre Channel interface. This daughter card architecture provides us with a cost
effective means to quickly implement next generation Fibre Channel integrated
circuits as well as configuration and manufacturing flexibility.

     Our hardware platforms use x86-based microprocessors, such as the Pentium
and Pentium II, and associated integrated circuits and memory modules, all of
which are widely used in the PC industry. As a result, we are able to develop
multiple generations of products that leverage the scalability, performance and
cost advantages of the high volume PC industry with minimal change to our
architecture.

RESEARCH AND DEVELOPMENT

     Our research and development expenses were approximately $1.4 million for
the year ended March 31, 1999, and $2.5 million for the nine months ended
December 31, 1999, excluding stock option compensation expense. We believe our
research and development efforts are essential to our ability to deliver
innovative products that address the needs of the market and influence the
evolving capabilities of the SAN. As of December 31, 1999, our staff included 31
people in our engineering, product development department and testing and
technical support departments. Our core hardware and software engineering teams
have worked together for approximately four years, including two years at
Adaptec prior to joining Chaparral.

     We possess a high level of multi-disciplinary technological expertise,
which we use in designing our products. This expertise includes the following
core competencies:

     - computer systems architecture and design;

     - embedded software design using advanced methodologies;

     - storage systems;

     - high-speed, high-density circuit design;

     - Fibre Channel and SCSI interface technologies; and

     - ASIC architecture and design.

     We believe that our expertise in these technologies provides us with
competitive advantages in time-to-market, price/performance, interoperability
and product capabilities. We focus our research and

                                       42
<PAGE>   44

development efforts on developing products that meet the evolving network
storage needs of our customers. For example, we are leveraging our expertise and
technology from our external RAID controllers to incorporate high-availability
features, such as active-active failover, into our future Intelligent Storage
Routers to meet the need for fault tolerance.

     In addition to the development of our core technologies, we plan to
continue to partner with other leading providers of network storage products and
services to jointly develop high-performance network storage solutions.

     Both our Intelligent Storage Routers and external RAID controllers have
been designed using a common modular architecture. This common architecture
facilitates a relatively short product design and development cycle and reduces
the time to market for our new products and features. We intend to continue to
leverage our common architecture to develop and introduce additional products
and embedded software enhancements in the future.

INTELLECTUAL PROPERTY

     Our success depends on our proprietary technology. We rely on a combination
of patents, trademarks and trade secrets, as well as confidentiality agreements
and other contractual restrictions with employees and third parties, to
establish and protect our proprietary rights. In November 1998, Adaptec granted
us a perpetual, worldwide license to the core technology that underlies our
products. The Adaptec license is exclusive to us except for the rights retained
by Adaptec to use this technology in non-competing products as described in the
license. Adaptec currently holds two United States patents with respect to this
core technology. Adaptec also has pending patent applications in the United
States with respect to certain aspects of the core technology and is seeking
patent protection for certain aspects of the technology in selected
international locations. However, it is possible that patents may not be issued
for these applications. Despite these precautions, third parties could copy or
otherwise obtain and use our products or technology without authorization, or
develop similar technology independently. The measures we undertake may not be
adequate to protect our proprietary technology, and these measures may not
preclude competitors from independently developing products with functionality
or features similar to our products. There can be no assurance that we can
prevent misappropriation or infringement of our technology.

     Litigation may be necessary in the future to enforce our intellectual
property rights, to protect our trade secrets or to determine the validity and
scope of the proprietary rights of others. Any intellectual property litigation
could result in substantial costs and diversion of our resources and could
significantly harm our business. We may receive notice of claims of infringement
of other parties' proprietary rights. Infringement or other claims could be
asserted or prosecuted against us in the future, and possible past or future
assertions or prosecutions could harm our business. Any such claims, with or
without merit, could be time-consuming, result in costly development and release
of our products, or require us to develop non-infringing technology or enter
into royalty or licensing arrangements. Such royalty or licensing arrangements,
if required, may not be available on terms acceptable to us, or at all. For
these reasons, infringement claims could significantly harm our business.

COMPETITION

     The markets for our products are becoming increasingly competitive and are
characterized by evolving standards and rapid technological change. We are
currently the only independent provider of both storage routers and external
RAID controllers. Our principal competitors in the storage router market are
ATTO, CrossRoads and Pathlight. We compete in the external RAID controller
market primarily with CMD, Infotrend and Mylex (acquired by IBM).

                                       43
<PAGE>   45

     We believe the primary competitive factors in the storage router and
external RAID controller markets are the following:

     - product performance, features and form factor;

     - product reliability and interoperability;

     - customer service and technical support;

     - price;

     - ability to meet delivery schedules;

     - OEM endorsement; and

     - strength of distribution channel.

     As the market for our products continues to grow, we may face competition
from traditional networking companies and other manufacturers of networking
equipment. These networking companies may enter the market by introducing their
own products or by acquiring or entering into an alliance with an existing
storage router or RAID controller provider. Our OEM customers could also develop
and introduce products that are competitive with our product offerings.

     Some of our current and potential competitors have longer operating
histories, significantly greater resources and name recognition and a larger
installed base of customers. As a result, these competitors may have greater
credibility with our existing and potential customers. They also may be able to
adopt more aggressive pricing policies and devote greater resources to the
development, promotion and sale of their products than we can to ours, which
would allow them to respond more quickly to new or emerging technologies and
changes in customer requirements. In addition, some of our current and potential
competitors have already established supplier or joint development relationships
with our current or potential customers. These competitors may be able to
leverage their existing relationships to discourage these customers from
purchasing additional products from us or persuade them to replace our products
with their products. Increased competition could result in pricing pressures,
reduced sales, reduced margins, reduced profits, reduced market share or the
failure of our products to achieve or maintain market acceptance.

     We may not have the financial resources, technical expertise or marketing,
manufacturing, distribution and support capabilities to compete successfully in
the future. Additionally, we may not be able to compete successfully against
current or future competitors and competitive pressures may significantly harm
our business.

MANUFACTURING

     We outsource our manufacturing, which reduces our need to make costly
investments in capital equipment and manufacturing facilities. SMTC and Saturn
currently manufacture our products and are responsible for nearly all material
procurement, assembly and testing, including in-circuit testing and functional
testing. We develop the architecture and drawings for our products and design
functional tests. Once our product passes all initial testing, it is shipped to
our facility, where we load all necessary microcode, perform final testing,
package and ship the product. As our product volume grows, we plan to outsource
all aspects of the manufacturing and shipping process.

     SMTC manufactures approximately 80% of our product volume in both its San
Jose, California, and Thornton, Colorado, facilities. Saturn manufactures our
products in Fremont, California. In addition, SMTC offers European distribution
capabilities. We place purchase orders with SMTC and Saturn based on periodic
forecasts. In the future, we may need to add new manufacturing partners to
achieve higher production volumes or lower costs or to secure second source
product availability.

     While our contract manufacturers are responsible for most facets of the
manufacturing process, we are directly involved in qualifying vendors and the
key components used in our products. While most of the
                                       44
<PAGE>   46

materials used in our products are standard and can be obtained from multiple
qualified manufacturers, some of our key components are proprietary or sole
sourced and require extended lead times. For example, we depend upon single
sources for our Fibre Channel, SCSI and memory controller ASICs. If we were
required to find new vendors for these sole-sourced components, we would have to
qualify replacement components and possibly reconfigure our hardware. This
qualification or reconfiguration process could result in product shipment
delays. Our supply management team works closely with strategically important
suppliers who offer proprietary or sole-sourced products. In addition, our
operations team is focused on developing production test equipment, designing
for manufacturability, transferring products effectively from development to
production and monitoring supplier performance and quality.

BACKLOG

     As of December 31, 1999, the backlog for our products was approximately
$794,000, all of which is scheduled for shipment to customers during the quarter
ended March 31, 2000. We had no significant backlog at March 31, 1999. All
orders are subject to cancellation or delay by customers with limited or no
penalty. Therefore, our backlog is not necessarily indicative of actual sales
for any succeeding period.

     Typically, our OEM customers forecast expected purchases on a three to
six-month rolling basis, as compared to distributor customers that order as
required with minimal order fulfillment time. OEM forecasts are not binding and
are subject to change.

EMPLOYEES

     As of December 31, 1999, we had 61 employees, all but two of whom are full
time and all but seven of whom were located at our principal offices in
Longmont, Colorado. Of the total number of employees, 31 employees were engaged
in research and development, 14 were in sales and marketing, six were in
manufacturing and ten were in finance, administration and information services.
None of our employees are represented by a labor union. We have not experienced
any work stoppages and consider our relations with our employees to be good.

     Our future performance depends in significant part upon the continued
service of our key technical, sales and senior management personnel. We only
have employment agreements requiring service for any defined period of time with
three of our executive officers. The loss of services of one or more of our key
employees could significantly harm our business, financial condition and results
of operations. Our future success also depends on our continuing ability to
attract, train and retain highly qualified technical, sales and managerial
personnel. Competition for such personnel is intense, and we may not be able to
retain our key personnel in the future.

LITIGATION

     We may from time to time become involved in various lawsuits and legal
proceedings that arise from actions taken in the ordinary course of our
business. As of the date of this prospectus, we are not a party to any legal
proceedings.

FACILITIES

     Our principal executive offices consist of approximately 20,000 square feet
located in Longmont, Colorado. We have a license, granted by Adaptec to occupy
our corporate headquarters facility on a month-to-month basis pursuant to a
license agreement that may be terminated by either Adaptec or us upon 30 days'
written notice. The monthly license fee is $25,439. We also have a license
granted by Adaptec to occupy approximately 1,325 square feet in Foothill Ranch,
California, pursuant to a license agreement that expires in May 2004. The
license is on a month-to-month basis, with a monthly license fee of $3,000.

     In response to our need for additional space to accommodate our growth
plans, we have signed an agreement to lease 40,000 square feet in Longmont,
Colorado from BTC Development, LLC, with

                                       45
<PAGE>   47

an option to lease up to an additional 20,000 square feet. This lease will
commence on March 15, 2000 and expire on March 31, 2005, with options to renew.
We have issued 42,000 shares of our common stock to BTC Development, LLC in lieu
of payment for approximately five months rent, or $126,000. We plan to relocate
our principal executive offices to this facility in the second calendar quarter
of 2000. We believe this facility will be adequate to meet our needs for the
foreseeable future.

     We have the exclusive use of two furnished private offices located in
Irvine, California pursuant to an office services agreement dated October 22,
1999 with VANTAS, Inc. The monthly charge for the use of these two offices is
$3,600. After the initial term expires on May 1, 2000, the office services
agreement will renew automatically every six months with a 5% increase in the
monthly charge upon each renewal.

STRATEGIC TECHNICAL ADVISORY COUNCIL

     The Strategic Technical Advisory Council, or STAC, was formed to provide
independent insight into the strategic product opportunities available to us.
The STAC assists our management in determining appropriate corporate strategies
and current and future product and application initiatives. The STAC meets
quarterly. In 1999, each member of our STAC received options to purchase 10,000
shares of our common stock, except that Mr. Trimmer received options for an
aggregate of 9,167 shares because he served less than a full year. For 2000,
each member of our STAC will receive an option to purchase 4,000 shares of our
common stock at an exercise price of $8.50 per share, which option vests in
equal quarterly installments commencing April 1, 2000. The STAC currently
consists of three members: Michael Peterson, F. Grant Saviers (see above) and
Don Trimmer.

     Michael Peterson has served on our STAC since January 1999. He has served
as President and Senior Analyst for Strategic Research Corporation since 1988.
Mr. Peterson was employed by Applied Magnetics from 1980 to 1988, by Sloan

CLASSIFIED BOARD OF DIRECTORS

     Following this initial public offering, our board of directors will be
divided into three classes of directors, as nearly equal in size as is
practicable, to serve staggered three-year terms:

     - Class I, whose term will expire at the annual meeting of stockholders to
       be held in fiscal 2001;

     - Class II, whose term will expire at the annual meeting of stockholders to
       be held in fiscal 2002; and

     - Class III, whose term will expire at the annual meeting of stockholders
       to be held in fiscal 2003.

     Each director's term will end on the election and qualification of his or
her successor, or his or her earlier death, resignation or removal.

COMMITTEES OF THE BOARD OF DIRECTORS

     Our board of directors has established an audit committee and a
compensation committee.

     The Audit Committee makes recommendations to our board of directors
regarding the selection of our independent auditors, reviews the results and
scope of our annual audits, reviews the fees to be paid to the auditors and
their performance, evaluates the compliance with our accounting and financial
policies and monitors management's procedures and policies relating to the
adequacy of our internal accounting controls. The members of the audit committee
are           ,           and           .

     The Compensation Committee reviews and makes recommendations to our board
of directors regarding our compensation policies and all forms of compensation
to be provided to our directors, executive officers and certain other employees.
In addition, the compensation committee reviews bonus and stock compensation
arrangements for all of our other employees. The compensation committee also
                                       49
<PAGE>   51

administers our stock option and employee stock purchase plan. The members of
the compensation committee are Mr. Saviers and           .

DIRECTORS COMPENSATION

     Directors currently do not receive any fees from us for their services as
directors, although by resolution of the board, they may receive a fixed sum and
reimbursement for expenses in connection with their attendance at board and
committee meetings. In the past, we have granted our outside director, Mr.
Saviers, options in lieu of cash compensation for his services as a director.
During the year ended March 31, 1999, we granted Mr. Saviers 50,000 shares of
common stock and an option to purchase 125,000 shares of our common stock at an
exercise price of $0.12 per share. During the nine months ended December 31,
1999, we granted Mr. Saviers an option to purchase 50,000 shares of our common
stock at a price of $3.19 per share, which option vests 25% after 12 months and
1/48th per month thereafter.

     Effective following this offering, each outside director will receive an
initial option to purchase 30,000 shares of our common stock upon being elected
to our board of directors under the 2000 stock incentive plan. In addition, each
outside director will receive an option to purchase 10,000 shares of our common
stock on the date of each annual meeting of stockholders, provided that he or
she has served as a director for at least six months. Each option will be
immediately exercisable for all of the option shares; however, we may
repurchase, at the exercise price paid per share, any shares purchased under the
option that are not vested at the time of the optionee's cessation of board
service. The shares subject to each initial 30,000-share automatic option grant
will vest in a series of three successive annual installments upon the
optionee's completion of each year of board service over the three-year period
measured from the grant date. The shares subject to each annual 10,000-share
automatic grant will vest upon the optionee's completion of one year of service
measured from the grant date. The shares will immediately vest in full upon
certain changes in control or ownership or upon the optionee's death or
disability while serving as a board member.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Our compensation committee is comprised of Mr. Saviers and           . No
member of our compensation committee currently serves, or has ever served, as an
officer or employee of Chaparral, and no executive officer or director of
Chaparral has ever served as a member of the compensation committee or board of
directors of an entity that had an executive officer who was also a member of
our compensation committee.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

     Our amended and restated certificate of incorporation limits the personal
liability of directors for breach of fiduciary duty to the maximum extent
permitted by Delaware law. Delaware law provides that directors of a corporation
will not be personally liable to us or our stockholders for monetary damages for
breach of their fiduciary duties as directors, except for:

     - any breach of the director's duty of loyalty to us or our stockholders;

     - acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - unlawful payments of dividends or unlawful stock repurchases, redemptions
       or other distributions; or

     - any transaction from which the director derived an improper personal
       benefit.

     Our bylaws require that we indemnify our directors and officers to the
extent permitted by Delaware law. We may, in our discretion, indemnify other
employees and agents to the extent permitted by Delaware law. We believe that
indemnification under our amended and restated certificate of incorporation and
bylaws cover at least negligence and gross negligence on the part of indemnified
parties. Our amended and restated certificate of incorporation also permits us
to secure insurance on behalf of any of our officers,
                                       50
<PAGE>   52

directors, employees or other agents for any liability incurred in that capacity
or arising out of that status, regardless of whether indemnification is
permitted under Delaware law.

     We have also entered into agreements to indemnify our directors and
officers. These agreements indemnify our directors and officers for some
expenses, including attorneys' fees, judgments, fines and settlement amounts
incurred by them in any action or proceeding, including any action by or in the
right of our company, arising out of their services as one of our directors or
officers, any of our subsidiaries or any other company or enterprise to which
the person provides services at our request. In addition, we have obtained
directors' and officers' insurance providing indemnification for some of our
directors, officers and employees for certain liabilities. We believe that these
provisions, agreements and insurance are necessary to attract and retain
qualified directors and officers.

     The limited liability and indemnification provisions in our certificate of
incorporation and bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful, might otherwise benefit us and our
stockholders. Moreover, a stockholder's investment in us may be adversely
affected to the extent we pay the costs of settlement or damage awards against
our directors and officers under these indemnification provisions.

     At present, there is no pending litigation or proceeding involving any of
our directors, officers, employees or agents where indemnification will be
required or permitted. We are not aware of any threatened litigation or
proceeding that might result in a claim for such indemnification.

EXECUTIVE COMPENSATION

     The following table provides the total compensation paid to our chief
executive officer and our other executive officers whose compensation (salary
and bonus) exceeded $100,000 in fiscal 1999. In addition to salary, Messrs.
Allison, Gluck and Walker did not receive personal benefits in excess of the
lesser of $50,000 or 10% of their respective annual salaries. Messrs. Gluck and
Walker did not receive salaries until May 1998. For fiscal year 2000, the board
of directors has established the salaries for Messrs. Allison, Gluck and Walker
at $180,000. The amounts listed under "All Other Compensation" represent
employer contributions to our 401(k) plan.

EMPLOYMENT AGREEMENTS

     We entered into a two-year employment agreement with Gary Allison, which
expired on February 28, 2000. Under the employment agreement, Mr. Allison agreed
to serve as our Chairman and Chief Executive Officer. Mr. Allison received as
compensation an option to purchase 1,000,000 shares at an exercise price of
$0.10 per share. Although the employment agreement provided for an annual salary
of $120,000 and quarterly bonus payments of $4,500, Mr. Allison was paid a
reduced salary for a portion of the year and a higher salary for the last half
of the year.

     We entered into two-year executive employment and noncompetition agreements
effective April 1, 2000 with Messrs. Allison, Gluck and Walker. Under these
agreements, Mr. Allison agrees to serve as Chairman of the Board and Chief
Executive Officer, Mr. Gluck agrees to serve as President and Chief Operating
Officer and Mr. Walker agrees to serve as Executive Vice President for
Engineering and Operations. The executive employment agreements are
automatically renewed for successive one-year periods unless terminated by
either party. The executive employment agreements provide for a minimum base
salary of $180,000 per year and a discretionary quarterly cash bonus of up to
25% of base salary for the period and/or additional stock options. Under the
executive employment agreements, the executive is entitled to participate in
company benefit plans.

     Our executive employment agreements provide for payments in the event of
termination of the executive's employment due to incapacity, death, cause and
other than for cause. In the event of termination due to incapacity or death,
the executive or his heirs will receive amounts equal to the executive's base
salary and bonus (at the rates in effect at the time of the termination) for one
year, which are reduced, in the case of incapacity, by amounts paid to him under
our long-term disability plans. Termination other than for cause also includes
termination by the executive for "good reason" in the event we:

     - assign them to duties that are inconsistent with or substantially
       diminished from their current responsibilities;

     - materially reduce their compensation and benefits;

     - relocate our offices to a location outside a 50-mile radius of Longmont,
       Colorado; or

     - breach the employment agreements in any material respect.

In the event of termination other than for cause, Messrs. Allison, Gluck and
Walker would be entitled to receive base salary and bonus and to continue to
participate in our employee benefit plans for one year. In addition, all stock
options held by them would immediately vest and remain exercisable for one year,
and restrictions imposed by us on any restricted stock would immediately lapse.

     Our executive employment agreements also provide benefits to Messrs.
Allison, Gluck and Walker in the event their employment is terminated within 180
days after a change in control of Chaparral, or if they choose to terminate
their own employment for good reason within that period. A change in control of
Chaparral is defined in the agreement to occur if:

     - any person or group were to become the beneficial owner of more than 50%
       of the then outstanding stock of Chaparral;

     - at any time during three consecutive years individuals who at the
       beginning of that period constitute the board of directors and others
       they elect ceased for any reason to constitute a majority of the board of
       directors; or

     - our stockholders approved a merger or consolidation of Chaparral with any
       other company in which our stockholders would have less than 80% of the
       combined voting power in the surviving entity or an agreement for the
       sale of substantially all of our assets.

                                       52
<PAGE>   54

For 180 days following a change in control, our executives may terminate their
employment with us for good reason if we or our successor company take any of
the actions described in the preceding paragraph as termination other than for
cause, or if the surviving company fails to assume their executive employment
agreements. In the event Messrs. Allison, Gluck or Walker is terminated after a
change of control or terminates his employment for good reason, he will be
entitled to receive a lump sum payment from us equal to two years base salary
and bonus and to continue to participate in our benefit plans for two years.
Each stock option not vested at the time of a change in control will be
accelerated by 12 months. An executive's options will be 100% vested if he is
terminated following a change in control or if the successor company does not
adopt our stock option plan in its entirety or convert to a plan of equivalent
value.

     Under our executive employment agreements, Messrs. Allison, Gluck and
Walker have agreed that during their employment and for a period of two years
following termination of their employment, they will not disclose our
confidential information and materials. Each of them also has agreed that he
will not solicit our customers or suppliers, attempt to hire away any of our
employees or knowingly engage in any activity that would harm our company or our
business relationships for a period of one year following termination of his
employment.

     We require each of our employees to enter into confidentiality agreements
prohibiting the employee from disclosing any of our confidential or proprietary
information. In addition, the agreements generally provide that upon
termination, the employee will not solicit our employees for a period of 12
months. At the time of commencement of employment, our employees also generally
sign offer letters specifying certain basic terms and conditions of employment.
Other than as described above, our employees are not subject to written
employment agreements.

OPTION GRANTS IN LAST FISCAL YEAR

     The following table provides information concerning individual grants of
stock options made during fiscal 1999 to our chief executive officer and our two
other most highly compensated executive officers. We have never granted any
stock appreciation rights.

     The exercise prices represent our board's estimate of the fair market value
of the common stock on the grant date. In establishing these prices, our board
considered many factors, including our financial condition and operating
results, recent transactions and the market for comparable stocks.

     The amounts shown as potential realizable value represent hypothetical
gains that could be achieved for the respective options if exercised at the end
of the option term. These amounts represent certain assumed rates of
appreciation in the value of our common stock. The 5% and 10% assumed annual
rates of compounded stock price appreciation are mandated by rules of the
Securities and Exchange Commission and do not represent our estimate or
projection of the future price of our common stock. The potential realizable
value is calculated based on the ten-year term of the option at its time of
grant. It is calculated based on the fair market value of our common stock on
the date of grant and assumes that the value appreciates at the indicated annual
rate compounded annually for the entire term of the option and that the option
is exercised and sold on the last day of its term for the appreciated stock
price. Actual gains, if any, on stock option exercises depend on the future
performance of our common stock. The options shown in the table have been
exercised, and the potential realizable values reflected in the table were not
achieved.

                                       53
<PAGE>   55

     We granted these options under our 1998 stock option plan. These options
were exercised in November 1998. We have the right to repurchase, at the
exercise price as adjusted, any shares as to which the repurchase right has not
lapsed at the time the optionee terminates employment with us. At the date of
exercise, we had the right to repurchase two-thirds of the shares acquired on
exercise, and the repurchase right lapses with respect to 1/24th of the
remaining shares each month thereafter. Our repurchase right terminates upon
completion of our initial public offering. The percentage of total options
granted to our employees in the last fiscal year is based on options to purchase
an aggregate of 5,851,000 shares of common stock granted during fiscal 1999. The
following table sets forth information concerning the individual grants of stock
options to our Chief Executive Officer and our two other most highly compensated
executive officers in fiscal 1999 and option values at March 31, 1999, assuming
the options remained unexercised.

AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION
VALUES

     The following table provides information about stock options exercised
during fiscal year 1999 and held as of March 31, 1999 by our Chief Executive
Officer and our two other most highly compensated executive officers. The value
realized is based on a value of $0.12 per share, the fair market value of our
common stock on the date of exercise, minus the per share exercise price,
multiplied by the number of shares underlying the option. As of March 31, 1999,
none of these executive officers held any unexercised options.

1998 STOCK OPTION PLAN

     On November 20, 1998, our board of directors and our stockholders approved
the 1998 stock option plan. Our board of directors amended the 1998 stock option
plan, effective June 1999 and September 1999, to increase the number of shares
of our common stock authorized for issuance under the plan. The purpose of the
1998 stock option plan is to strengthen our company by providing an incentive to
our employees, officers, consultants and directors through the granting or
awarding of incentive and nonqualified stock options, thereby encouraging them
to devote their abilities and energies to our success.

     The 1998 stock option plan is administered by our board of directors. Under
the 1998 stock option plan, our board of directors has the authority to delegate
administration of the 1998 stock option plan to a committee acting under the
authority of our board of directors. Our board of directors, or a committee
delegated administration of the 1998 stock option plan, has authority to, among
other things, grant options,

                                       54
<PAGE>   56

select persons to whom awards will be granted, determine the type, size and the
terms and conditions of awards.

     Under the 1998 stock option plan, 14,000,000 shares of common stock are
authorized and reserved for the grant of awards to eligible individuals. Awards
granted under the 1998 stock option plan are exercisable over a ten-year period.
As of December 31, 1999, options to purchase 10,488,163 shares of common stock
have been granted, of which options to purchase 6,788,332 shares of common stock
have been exercised. The 1998 stock option plan will terminate on November 19,
2008. Our board of directors may at any time and from time to time amend or
terminate the 1998 stock option plan; provided, however, that no amendment will
be effective without the approval of a majority of the stockholders if the
amendment will increase the number of shares which may be granted or expand the
class of persons who can receive incentive stock options.

2000 STOCK INCENTIVE PLAN

     The 2000 stock incentive plan will become effective upon completion of our
initial public offering. The 2000 stock incentive plan was approved by our board
of directors on February 21, 2000 and by our stockholders on             , 2000.

     Share reserve. We have authorized           shares of our common stock for
issuance under the incentive plan, which amount includes           shares of
common stock authorized but unissued under our 1998 stock option plan. The share
reserve under the incentive plan will automatically increase on the first
trading day in January of each calendar year, beginning with calendar year 2001,
by an amount equal to 4.5% of the total number of shares of our common stock
outstanding on the last trading day of December in the prior calendar year, but
in no event will this annual increase exceed 4,000,000 shares.

     Programs. The incentive plan has five separate programs:

     - the discretionary option grant program, under which eligible employees
       may be granted options to purchase shares of our common stock at an
       exercise price not less than the fair market value of those shares on the
       grant date;

     - the stock issuance program, under which eligible individuals may be
       issued shares of common stock directly, upon the attainment of
       performance milestones, the completion of a specified period of service
       or as a bonus for past services;

     - the salary investment option grant program, under which our executive
       officers and other highly compensated employees may be given the
       opportunity to apply a portion of their base salary each year to the
       acquisition of stock option grants with an exercise price between 85% and
       100% of the fair market value of a share of common stock;

     - the automatic option grant program, under which option grants will
       automatically 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; and

     - the director fee option grant program, under which our non-employee board
       members may be given the opportunity to apply a portion of any director
       fee otherwise payable to them in cash each year to the acquisition of
       option grants.

     Eligibility. The individuals eligible to participate in the incentive plan
include our officers and other employees, our non-employee board members and any
consultants we hire.

                                       55
<PAGE>   57

     Administration. The discretionary option grant and stock issuance programs
will be administered by our board of directors, but the board may delegate such
authority in whole or in part to a primary committee. The board or the primary
committee will determine:

     - the eligible individuals who 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.

The board of directors or the primary committee will also have the authority to
select the executive officers and other highly compensated employees who may
participate in the salary investment option grant program in the event that
program is put into effect for one or more calendar years.

     Change in control. The incentive plan includes the following change in
control provisions, which may result in the accelerated vesting of outstanding
option grants and stock issuances. A change in control of Chaparral is defined
in the incentive plan to occur if:

     - any person or group were to become the beneficial owner of more than 50%
       of the then outstanding voting stock of Chaparral;

     - at any time during three consecutive years individuals who at the
       beginning of that period constitute the board of directors and others
       they elect ceased for any reason to constitute a majority of the board of
       directors; or

     - our stockholders approved a merger or consolidation of Chaparral with any
       other company in which our stockholders would have less than 80% of the
       combined voting power in the surviving entity or an agreement for the
       sale of substantially all of our assets.

     Discretionary option grant program. Under this program, eligible persons
(employees, non-employee members of our board of directors and consultants) may
receive options to purchase shares of common stock at the discretion of our
board of directors. The exercise price per share is fixed by the plan
administrator and may be less than, equal to or greater than fair market value.
No option granted under this program shall have an exercise term greater than
ten years. Incentive stock options may be granted to employees under the program
at an exercise price not less than the fair market value per share. Chaparral
may repurchase, at the exercise price paid per share, any shares purchased under
the option which are not vested at the time of the optionee's cessation of
employment.

     Stock issuance program. In the event our board of directors decides to put
this program into effect, our employees, non-employee members of our board of
directors and consultants may receive shares of common stock or share right
awards at the discretion of our board. The purchase price per share is fixed by
the plan administrator and may be less than, equal to or greater than the fair
market value per share. The plan administrator may issue shares of common stock
that fully and immediately vest or that vest in one or more installments over
the participant's employment period or upon attainment of specific performance
objectives.

     Salary investment option grant program. In the event our board of directors
decides to put this program into effect for one or more calendar years, each of
our executive officers and other highly compensated employees may elect to
reduce his or her base salary for the calendar year by an amount not less than
$5,000 nor more than $50,000. Each selected individual who makes such an
election will automatically be granted, on the first trading day in January of
the calendar year for which his or her salary reduction is to be in effect, an
option to purchase that number of shares of common stock

determined pursuant to a formula contained in the plan. Each option will have an
exercise price per share that may range from 85% to 100% of the fair market
value of the option shares on the grant date. As a result, the option will be
structured so that the fair market value of the option shares on the grant date
less the exercise price payable for those shares will be equal to the amount of
the salary reduction. The option will become exercisable in a series of 12 equal
monthly installments over the calendar year for which the salary reduction is to
be in effect.

     Automatic option grant program. Each individual who first becomes a
non-employee board member at any time after the effective date of this offering
will receive a non-qualified option grant to purchase 30,000 shares of common
stock on the date such individual joins the board. In addition, on the date of
each annual stockholders meeting held after the effective date of this offering,
each non-employee board member who is to continue to serve as a non-employee
board member, including each of our current non-employee board members, will
automatically be granted an option to purchase 10,000 shares of common stock;
provided such individual has served on the board for at least six months.

     Each automatic grant will have an exercise price per share equal to the
fair market value per share of our common stock on the grant date and will have
a term of ten years, subject to earlier termination upon the optionee's
cessation of board service. The option will be immediately exercisable for all
of the option shares; however, we may repurchase, at the exercise price paid per
share, any shares purchased under the option which are not vested at the time of
the optionee's cessation of board service. The shares subject to each initial
30,000-share automatic option grant will vest in a series of three successive
annual installments upon the optionee's completion of each year of board service
over the three-year period measured from the grant date. The shares subject to
each annual 10,000-share automatic grant will vest upon the optionee's
completion of one year of service measured from the grant date. However, the
shares will immediately vest in full upon certain changes in control or
ownership or upon the optionee's death or disability while then serving as a
board member.

     Director fee option grant program. If this program is put into effect in
the future, then each non-employee board member may elect to apply all or a
portion of any cash retainer fee for the year to the acquisition of a
below-market option grant. The option grant will automatically be made on the
first trading day in January of the calendar year for which the non-employee
board member would otherwise be paid the cash retainer fee in the absence of his
or her election. The option will have an exercise price per share ranging from
85% to 100% of the fair market value of the option shares on the grant date, and
the number of shares subject to the option will be determined pursuant to a
certain formula contained in the incentive plan. As a result, the option will be
structured so that the fair market value of the option shares on the grant date
less the exercise price payable for those shares will be equal to the portion of
the retainer fee applied to that option. The option will become exercisable in a
series of 12 equal monthly installments over the calendar year for which the
election is in effect. However, the option will become immediately exercisable
for all the option shares upon the death or disability of the optionee while
then serving as a board member.

2000 EMPLOYEE STOCK PURCHASE PLAN

     Introduction. Our employee stock purchase plan was adopted by our board of
directors on February 21, 2000 and was approved by our stockholders on
            , 2000. The purchase plan is designed to allow our eligible
employees and the eligible employees of our participating subsidiaries, if any,
to purchase shares of common stock at semi-annual intervals with their
accumulated payroll deductions. The purchase plan will become effective on
completion of our initial public offering.

     Share reserve. We have initially reserved 6,000,000 shares of our common
stock for issuance under the purchase plan. The reserve will automatically
increase on the first trading day of January in each calendar year, beginning in
calendar year 2001, by an amount equal to 2% of the total number of outstanding
shares of our common stock on that date or a lesser amount determined by our
board of directors. In no event will any such annual increase exceed 1,000,000
shares.

                                       57
<PAGE>   59

     Offering periods. The purchase plan has a series of successive offering
periods, each continuing until terminated by our board of directors. The initial
offering period will begin when the Securities and Exchange Commission declares
our registration statement effective and will end on the last trading day on or
before July 31, 2000. The next offering period will start on the first business
day in August 2001, and subsequent offering periods will be set by our board of
directors.

     Eligible employees. Individuals scheduled to work more than 20 hours per
week for more than five calendar months per year may join an offering period
after they have been with us for six months. 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 10% of his or her
base salary 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 May and November each
year.

     Change in control. In the event of a change in control, which is defined in
the purchase plan in the same way it is defined in the incentive plan, all
outstanding purchase rights will automatically be exercised immediately prior to
the effective date of the change in control. 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.

     Termination and amendment of purchase plan. The purchase plan will
terminate no later than February 21, 2010. The board may at any time amend,
suspend or discontinue the purchase plan. Some amendments, however, may require
stockholder approval.

401(K) PLAN

     Our profit sharing plan allows employees to defer up to 15% of their
compensation, up to a maximum of $10,500 in the year 2000. We will match these
funds with a percentage to be determined by our board of directors on a
quarterly basis. We may contribute an additional amount at the end of the fiscal
year at the discretion of our board of directors. Mr. Lehrmann serves as trustee
of the profit sharing plan. Our 401(k) profit sharing plan was adopted in
November 1998.

     By letter agreement dated November 1998, Mr. Saviers, a director, agreed to
purchase up to 2,500,000 shares of Series A preferred stock at a price of $0.10
per share. Mr. Saviers conditioned his purchase on the following:

     - the sale by Adaptec of certain assets;

     - the rights, preferences, privileges and restrictions of the Series A
       preferred stock being as stated in the amended and restated certificate
       of incorporation;

     - the issuance of the Series A preferred stock being on terms and
       conditions not inferior to the terms and conditions of the Series B
       preferred stock issued to Adaptec; and

     - his continued service as a member of the board of directors.

Mr. Saviers purchased 2,500,000 shares on Series A preferred stock on November
27, 1998.

     Mr. Childs, a greater than 5% stockholder, purchased 400,000 shares at
$0.50 per share, on July 10, 1998. Those shares were subsequently repriced on
October 19, 1998, at $0.10 per share for a total purchase of 2,000,000 shares.
In addition, we issued 2,500,000 shares of Series A preferred stock to Mr.
Childs pursuant to a $250,000 convertible debenture dated August 5, 1998. The
convertible debenture was due February 5, 1999, accrued interest at 8% per year
and was unsecured. We also issued 1,500,000 shares to Mr. Childs at $0.10 per
share.

     Series B Preferred Stock. On November 25, 1998, we issued 5,540,200 shares
of our Series B preferred stock to Adaptec in connection with our purchase of
certain assets from Adaptec. See "-- Agreements with Adaptec."

     Series C Preferred Stock. Effective October 15, 1999, we issued Woodcarvers
1,763,637 shares of our Series C preferred stock at $0.44 per share and
1,900,000 shares at $0.50 per share.

     Warrants. Pursuant to a financial consulting agreement, we issued warrants

common stock to Mr. Childs as payment of financing fees for loans Mr. Childs
made to us. These loans are discussed below under the caption "-- Loans." Mr.
Childs exercised his warrants in full on January 25, 2000.

     On August 19, 1999, we granted each of Messrs. Allison and Gluck a warrant
to purchase up to 10,000 shares of common stock at an exercise price of $0.25
per share. These warrants were granted in lieu of cash payment for fees due on
loans from Messrs. Allison and Gluck to us. These warrants expire to

the extent they are not exercised on the earlier of August 18, 2004 or
commencement of our initial public offering.

     Pursuant to the warrant agreements by which we granted most of the warrants
discussed above, we also granted certain registration rights with respect to
524,507 shares of common stock issued upon exercise of the warrants. See
"Description of Capital Stock -- Summary of Registration Rights" for details of
these registration rights.

     When we signed a three-year Integrated Circuit Agreement with Adaptec on
March 1, 2000, we issued a warrant to Adaptec to purchase 300,000 shares of our
common stock at an exercise price of $20 per share. This warrant is not
exercisable for a period of nine months and terminates to the extent unexercised
after 15 months.

  Loans.

     During January and February 1998, Chaparral Systems, Inc., an entity whose
sole stockholder is Mr. Allison, loaned us the following amounts:

These loans were evidenced by promissory notes that were payable on demand. The
$29,000 in principal and $350 of interest due on these notes was paid in cash on
March 24, 1998.

     In April and June 1998, Chaparral Systems loaned us additional amounts, as

</TABLE>

These loans were evidenced by promissory notes that were payable on demand. The
principal amounts on these notes were repaid as of November 24, 1998 by our
issuing to Mr. Allison 875,000 shares of Series A preferred stock.

     On February 3, 1999, Messrs. Allison and Gluck each loaned us $25,000. Each
note is unsecured and accrues interest at the rate of 8% per year. The note also
stated a fee of 10% payable in cash or in the form of a warrant to purchase
10,000 shares of common stock at $0.25 per share. These notes were repaid by us
on August 19, 1999, and each of Messrs. Allison and Gluck took his fee in the
form of warrants.

     On February 3, 1999, Mr. Saviers loaned us $75,000, evidenced by a
promissory note. The note is unsecured and accrued interest at the rate of 8%
per year, compounded. The note also stated a fee of 10% ($7,500) payable in cash
or in the form of a warrant to purchase shares of common stock at a price per
share equal to 50% of the price per share paid by investors in our subsequent
private placement. This note was originally due on March 31, 1999, but was
subsequently extended to June 30, 1999. The note was repaid by our issuance to
him of 300,000 shares of Series A preferred stock at $0.25 per share, effective
as of February 3, 1999. No payment was made for interest or the 10% financing
fee.

(1) The aggregate principal amount of $1,050,000 and interest of $10,882 were
    paid on December 13, 1999.

(2) Interest was paid directly to Silicon Valley Bank, from whom Mr. Childs had
    borrowed the funds that he lent to us, in an amount equal to the prime rate
    plus 1% and additional interest of 1% or $7,375 was paid to Mr. Childs.

(3) Principal of $250,000 and interest of $4,741 were paid on August 13, 1999.

     On November 25, 1998, we made loans to each of our executive officers and
to Brian Allison, our Vice President of Sales and Mr. Allison's son, in
connection with the purchase by each of them of shares of our common stock upon
early exercise of options. Each loan is evidenced by a promissory note, which is
unsecured and accrues interest at the rate of 6% per year, compounded annually.
Each note is repayable upon the earliest of the resale of the shares of our
common stock, a change in control of Chaparral, within 90 days following the
individual's termination of employment or November 25, 2008. These loans are
summarized below:

     From January 1999 through August 1999, Woodcarvers issued 21 promissory
notes payable to us in the aggregate amount of $2,743,000 as payment of the
purchase for shares of our Series A preferred stock, Series C preferred stock
and common stock. The notes bore interest at the rate of 8%, were payable on
demand and had stated maturities of two months or less. The last promissory note
was paid on October 18, 1999.

     On July 5, 1999, we entered into a Support Agreement with each of Messrs.
Allison and Lehrmann for the benefit of Wells Fargo Business Credit, Inc. as
part of the Credit and Security Agreement entered into on the same day between
us and Wells Fargo. Pursuant to each Support Agreement, we and the executive
officer agreed that if Wells Fargo came into possession of any of the collateral
securing the Credit and Security Agreement because of an event of default on the
Credit Agreement, then we and the executive officer would incur certain
obligations. If the executive officer were still employed by us, we would cause
him to exert his best efforts to obtain sales of the collateral at the best
commercially obtainable prices and collect the accounts. If the executive
officer ceased to be employed by us, he was required to assist Wells Fargo as
its independent contractor, for a period not to exceed 150 days, for the

                                       63
<PAGE>   65

purpose of disposing of the collateral and collecting the accounts. In the
latter circumstance, Wells Fargo was required to pay the executive officer a
weekly salary at 115% of the average salary paid to him by us in the 12 months
preceding the commencement of such services. If the executive officer failed to
fulfill his obligations, he was required to pay Wells Fargo $50,000 in
liquidated damages, as well as costs and expenses incurred in enforcing the
liquidated damages provision. If the executive officer died, became mentally or
physically incapacitated or ceased to be employed by us, we were required to
replace him and use our best efforts to cause his replacement to execute a
support agreement. Both Support Agreements terminated when we terminated the
Credit and Security Agreement in January 2000.

     Also on July 5, 1999, Mr. Childs entered into a Subordination Agreement for
the benefit of Wells Fargo. Pursuant to the Subordination Agreement, Mr. Childs
agreed to subordinate promissory notes for an aggregate principal amount of
$1,050,000, payable by us to Mr. Childs, to each debt, liability and obligation
that we would owe to Wells Fargo under the credit agreement. This Subordination
Agreement was terminated when we terminated our Credit Agreement with Wells
Fargo in January 2000.

  Agreements with Adaptec

     Initial Agreements. We entered into a Memorandum of Understanding with
Adaptec in December 1997. The agreement was amended in March 1999, under which
Chaparral was granted a license to modify the Adaptec External Fibre Channel
RAID controller and adapt it to the storage router market. Adaptec agreed to
provide up to $200,000 of funding in exchange for a 19.9% equity interest in
Chaparral in the form of a one year convertible debenture at 5% interest. In
July 1998 Adaptec decided to divest its Fibre Channel technology, and in
September 1998 we entered into a Memorandum of Understanding to license and to
purchase certain Fibre Channel RAID controller technology and assets. In
conjunction with this Memorandum of Understanding, Adaptec provided an
additional $550,000 loan advance on similar terms to the original loans. The
$550,000 loan was repaid by Chaparral on November 25, 1998 in connection with
the Adaptec Asset Transfer Agreement and Contribution Agreement discussed below.

     Asset Transfer Agreement. On November 25, 1998, we entered into an Asset
Transfer Agreement with Adaptec. Pursuant to the Asset Transfer Agreement, we
received certain tangible assets and inventory, copies of Adaptec's marketing
and sales information and a license to use certain assets of Adaptec. In return,
we issued to Adaptec 5,540,200 shares of our Series B preferred stock. As a
result of this transaction, Adaptec owns 100% of the outstanding Series B
preferred stock. In connection with the Asset Transfer Agreement and on the same
date, we entered into an Investors' Rights Agreement, a Contribution Agreement,
a Technology Cross-License Agreement, a Board Manufacturing and Transition
Agreement and an Occupancy License Agreement, all of which are summarized below.

     Fourth Amended Investors' Rights Agreement. Under the Fourth Amended
Investors' Rights Agreement entered into as of March 1, 2000, Adaptec and
holders of our Series A preferred stock, Series B preferred stock and Series C
preferred stock received information rights, the registration rights described
in "Description of Capital Stock -- Registration Rights" and a right of first
refusal to purchase, in some specified circumstances, a pro-rata share of
certain securities that we may issue from time to time (pre-emptive rights). In
addition, Adaptec was permitted to have one representative attend all meetings
of our board of directors in a non-voting, observer capacity.

     Pre-emptive rights are not applicable to certain stock issuances,
including, among others:

     - up to 8,000,000 shares of our common stock issued to employees, officers,
       directors or consultants pursuant to incentive agreements or plans;

     - securities offered to the public pursuant to a registration statement;

     - securities issued in a merger or acquisition; and

     - up to 3,000,000 shares of our common stock (and/or options or warrants
       therefor) issued or issuable in connection with strategic alliances or
       partnering arrangements approved by our board of directors.

                                       64
<PAGE>   66

Preemptive rights terminate immediately before the closing of our initial public
offering.

     Contribution Agreement. Under the Contribution Agreement with Adaptec and
certain of our stockholders, we issued 5,540,200 shares of our Series B
preferred stock to Adaptec in exchange for the transfer by Adaptec of the assets
set forth in the Asset Transfer Agreement and in exchange for the cancellation
of debt owed by us to Adaptec. In addition, we issued an aggregate of 1,875,000
shares of our common stock and an aggregate of 1,150,000 shares of our Series A
preferred stock to certain of our stockholders, including 250,000 shares of
Series A preferred stock and 1,000,000 shares of common stock to Mr. Allison,
and 900,000 shares of Series A preferred stock to Mr. Childs, in exchange for
their agreement to cancel debt owed by us to each of them. The debt owed to
Adaptec and to each stockholder was evidenced by various promissory notes, all
of which were delivered to us and canceled. All parties to the Contribution
Agreement that received our stock agreed that upon our request or the request of
the underwriters managing any public offering of our securities under the
Securities Act, they will not sell or otherwise dispose of the shares acquired
for a period of 180 days without our consent or the managing underwriters'
consent.

     Technology Cross-License Agreement. Under the Technology Cross-License
Agreement, Adaptec granted us an irrevocable and perpetual worldwide license to
use certain technology related to Adaptec's business. In addition, we granted
Adaptec an irrevocable, worldwide and nonexclusive license to use, copy and
modify certain software. Each party agreed to indemnify the other for any claims
arising from the infringement on any third party's intellectual property rights
licensed under the agreement.

     Board Manufacturing and Transition Agreement. Under the Manufacturing
Agreement, Adaptec agreed to purchase, assemble and manufacture certain of the
products the technology for which was transferred to us under the Asset Purchase
Agreement during a transition period not to extend beyond April 30, 1999.
Adaptec, however, continued manufacturing our products until August 31, 1999.

     Occupancy License Agreements. On March 15, 1998, we entered into an
Occupancy License Agreement with Adaptec, under which Adaptec granted us a
nonassignable, non-transferable right and revocable license for the use of
approximately 7,573 square feet of space in Longmont, Colorado, on a
month-to-month basis at a monthly license fee of $7,573. On October 1, 1998, we
entered into a new Occupancy License Agreement with Adaptec pursuant to which we
licensed additional space at the same location for a total of approximately
20,000 square feet. This license was for a period of nine months at a monthly
license fee of $25,440. The original term of the license was nine months, but
the parties amended the agreement on July 15, 1999 to extend the term on a
month-to-month basis. We also entered into a similar agreement with Adaptec on
May 10, 1999 to occupy 1,325 square feet of space located in Foothill Ranch,
California. The license for the California property is for a period of 60
months, with a monthly license fee of $2,700 for the first 30 months, and $2,850
for months 31-60. Upon commencement of our occupancy under this license, an
Occupancy License Agreement with Adaptec that we entered into on October 1, 1998
to occupy approximately 1,000 square feet of space in Irvine, California at a
monthly license fee of $3,000 was terminated.

     Integrated Circuit Agreement. On March 1, 2000, we signed an Integrated
Circuit Agreement with Adaptec. Pursuant to this agreement, Adaptec agreed to
sell and we agreed to buy ASICs for a term of three years. The agreement also
provides that in certain circumstances, including the bankruptcy of Adaptec or
breach by Adaptec of the agreement, we have certain backup rights to the
technology for the ASIC. These backup rights enable us to purchase ASICs
directly from Adaptec's manufacturer or to select our own manufacturer to
produce the ASIC for us using the technology from Adaptec. As part of the
Integrated Circuit Agreement, we issued to Adaptec a warrant to purchase 300,000
shares of our common stock at a purchase price of $20 per share.

INDEMNIFICATION

     We have entered into indemnification agreements with each of our directors
and officers. Such indemnification agreements require us to indemnify our
directors and officers to the fullest extent permitted by Delaware law. See
"-- Limitation of Liability and Indemnification."

CONFLICT OF INTEREST POLICY

     We believe that all transactions with affiliates described above were made
on terms no less favorable to us than could have been obtained from unaffiliated
third parties. Our policy is to require that a majority of the independent and
disinterested outside directors on our board of directors approve all future
transactions between us and our officers, directors, principal stockholders and
their affiliates. Such transactions will continue to be on terms no less
favorable to us than we could obtain from unaffiliated third parties.

                             PRINCIPAL STOCKHOLDERS

     The following table sets forth certain information regarding the beneficial
ownership of our common stock as of March 1, 2000 and after giving effect to
this offering, but without giving effect to the exercise of the underwriters'
over-allotment option, by:

     - each person known by us to beneficially own more than 5% of our common
       stock;

     - each executive officer named in the Summary Compensation Table on page
       51;

     - each of our directors; and

     - all of our executive officers as a group.

     Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission and includes voting and investment power with
respect to the securities. Except as indicated by footnote, the persons named in
the table have sole voting and investment power with respect to all shares of
common stock shown as beneficially owned by them. The number of shares of common
stock used to calculate the percentage ownership of each listed person includes

                          DESCRIPTION OF CAPITAL STOCK

     Currently, our authorized capital stock consists of 52,000,000 shares of
common stock, par value $0.001 per share, and 29,140,200 shares of preferred
stock, par value $0.001 per share. Upon completion of this offering, our
authorized capital stock will consist of 120,000,000 shares of common stock, par
value $0.001 per share, and 40,000,000 shares of preferred stock, par value
$0.001 per share. The following summary is qualified by reference to our
certificate of incorporation and our bylaws, forms of which have been filed as
exhibits to the registration statement of which this prospectus is a part.

COMMON STOCK

     As of December 31, 1999, there were 17,860,158 shares of common stock
outstanding that were held of record by 60 stockholders. Holders of our common
stock are entitled to one vote for each share held on all matters to be voted
upon by stockholders, including the election of directors. Our certificate of
incorporation does not provide for cumulative voting for the election of
directors, and as a result, minority stockholders will not be able to elect
directors on the basis of their votes alone.

     Subject to limitations under Delaware law and preferences that may apply to
any outstanding shares of preferred stock, holders of common stock are entitled
to receive ratably dividends or other distributions, if any, that may be
declared by our board of directors out of legally available funds. In the event
of our liquidation, dissolution or winding up, holders of common stock are
entitled to share ratably in all assets remaining after payment of liabilities,
subject to the liquidation preference of any outstanding preferred stock. Our
common stock has no preemptive, conversion or other rights to subscribe for
additional securities of Chaparral. All outstanding shares of common stock are,
and all shares of common stock to be outstanding upon completion of the offering
will be, validly issued, fully paid and nonassessable. The rights, preferences
and privileges of holders of common stock are subject to, and may be adversely
affected by, the rights of the holders of shares of any series of preferred
stock that we may designate and issue in the future.

PREFERRED STOCK

     As of December 31, 1999, there were 18,599,372 shares of Series A preferred
stock outstanding, 5,540,200 shares of Series B preferred stock outstanding and
5,000,000 shares of Series C preferred stock outstanding. Upon the closing of
this offering, all outstanding shares of Series A, Series B and Series C
preferred stock will automatically convert into 15,128,853 shares of common
stock.

     Our board of directors will have the authority, without further approval of
the stockholders, to issue up to 10,859,800 shares of preferred stock in one or
more series, to fix the rights, preferences, privileges and restrictions of the
authorized preferred stock and to issue shares of each such series. The issuance
of preferred stock, while providing flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of restricting
dividends on the common stock, diluting the voting power for the common stock,
impairing the liquidation rights of the common stock, delaying or preventing a
change in control of our company, discouraging bids for our common stock at a
premium or otherwise adversely affecting the market price of our common stock.

WARRANTS

     Other than the warrants granted to directors, executive officers and
greater than 5% stockholders described in "Certain Transactions -- Warrants,"
there were outstanding as of March 1, 2000 warrants to purchase up to an
aggregate of 84,741 shares of our common stock held by two people. These
warrants may be exercised at prices ranging from $0.01 per share to $0.80 per
share. Warrants to purchase 1,250 shares terminate on September 8, 2001, 63,491
shares terminate on November 8, 2004, and 20,000 shares terminate on December
13, 2004. These warrants automatically terminate if they are not exercised prior
to our initial public offering.

REGISTRATION RIGHTS

     Holders of all shares of our preferred stock and certain shares of our
common stock have registration rights.

  Fourth Amended Investors' Rights Agreement

     Pursuant to the Fourth Amended Investors' Rights Agreement, dated March 1,
2000, certain of our investors have registration rights. These rights include
demand registration rights, piggyback registration rights and Form S-3
registration rights.

     Demand Registration Rights. If we receive a written request from the
holders of at least two-thirds of the registrable securities (as defined in the
agreement) after six months of our initial public offering that we file a
registration covering the registrable securities, then we will give notice to
all holders of registrable securities of the request within 20 days, and file a
registration statement as soon as practicable covering the shares of all holders
who request such registration. Our obligation is contingent on at least 25% of
all registrable securities then outstanding requesting to have their shares
included in the registration statement.

     Piggyback Registration Rights. If we file a registration statement we must
notify all holders of registrable securities 30 days prior to the filing of such
registration statement. Each holder then has an opportunity to include his or
her shares in the registration provided that he or she notifies us within 20
business days of receiving notice from us.

     Form S-3 Registration Rights. If we receive a written request from holders
of at least 25% of the then outstanding registrable securities to file a Form
S-3 with respect to the registrable securities, then we will promptly give
notice to each holder, effect such registration as soon as practicable and pay
all registration expenses. We are not obligated to effect such registration,
however, if:

     - the aggregate offering price of all shares included in the proposed
       registration is less than $1.0 million;

     - we determine in good faith that such registration would be seriously
       detrimental to us and our stockholders (in which case we can defer such
       registration for 120 days); or

     - we have already effected two registrations on Form S-3 in the last 12
       months.

  Warrant Agreements

     Pursuant to the terms of various warrant agreements, Harvest Storage
Technology, Mr. Gluck, Mr. Allison, Mr. Childs and Sentinel Consulting each have
demand registration rights and piggyback registration rights with respect to
524,508 shares of our common stock.

     Demand Registration Rights. If we receive a written request from Harvest
Storage Technology, Mr. Gluck, Mr. Allison, Mr. Childs or Sentinel Consulting
within six months of an initial public offering that we file a registration
statement covering registrable securities (defined as shares of common stock
issued upon exercise of the warrants) having a value of at least $1.0 million,
we are required to use our best efforts to file promptly a registration
statement covering all of the shares requested to be included. Each warrant
agreement grants each of Harvest Storage Technology, Mr. Gluck, Mr. Allison, Mr.
Childs and Sentinel Consulting one such demand registration, and such demand may
not be made during the period starting 60 days prior to the estimated date of
filing our initial registration statement and ending on the date six months
following our initial public offering.

     Piggyback Registration Rights. If we file a registration statement, other
than on Form S-8 or other similar form or in connection with a Rule 145
transaction, we must promptly notify Harvest Storage Technology, Mr. Gluck, Mr.
Allison, Mr. Childs and Sentinel Consulting prior to the filing of such
registration statement. Harvest Storage Technology, Sentinel Consulting and
Messrs. Gluck, Allison and Childs then each have an opportunity to include their
shares in the registration statement; provided that

                                       70
<PAGE>   72

each notifies us within 20 business days of receiving our notice. Each warrant
agreement grants each of Harvest Storage Technology, Sentinel Consulting, Mr.
Gluck, Mr. Allison and Mr. Childs three such piggyback registration rights.

PROVISIONS IN OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND BYLAWS
AND IN DELAWARE LAW THAT MAY HAVE ANTI-TAKEOVER EFFECTS

     Our certificate of incorporation and bylaws will be amended and restated as
of the date of completion of this offering. Our amended and restated certificate
of incorporation and bylaws will contain certain provisions that may have the
effect of delaying, deferring or preventing a third party from acquiring us,
even if the acquisition would benefit our stockholders.

     Our amended and restated certificate of incorporation and bylaws provide
that our board of directors shall consist of three classes of directors, each
serving for a three-year term ending in successive years. This provision may
make it more difficult to effect a takeover because it would generally take more
than one annual meeting of our stockholders for an acquiring party to elect a
majority of the board of directors. As a result, a classified board of directors
may discourage proxy contests for the election of directors or purchases of a
substantial block of our stock because it could operate to prevent a potential
acquiror from obtaining control of our board of directors in a relatively short
period of time.

     In addition, our amended and restated certificate of incorporation and
bylaws will provide that stockholders may take action only at a duly called and
held meeting and may not take action by written consent. This provision may make
it more difficult to effect a takeover through various types of transactions,
such as a merger or sale of assets, by requiring a potential acquiror to hold a
stockholders' meeting before such a transaction could be consummated.

     Our amended and restated certificate of incorporation and bylaws also will
provide that the "staggered board" provision and the provisions concerning
voting rights of stockholders may be amended only by a vote of two-thirds of the
outstanding shares of our capital stock entitled to vote generally in the
election of directors, voting as a single class.

     Finally, we are subject to Section 203 of the Delaware General Corporation
Law, which imposes restrictions on certain business combinations with interested
persons. That section defines an "interested person" as any person who acquires
15% or more of our outstanding voting stock. In general, we are prohibited from
engaging in business combinations with an interested person for a period of
three years from the date that person becomes an interested person, subject to
certain exceptions. By restricting our ability to engage in business
combinations with an interested person, the application of Section 203 may
provide a barrier to takeovers not approved in advance by our board of
directors.

DIVIDENDS

     We have not paid any cash dividends on our common stock or preferred stock
and intend to retain future earnings to finance our business. We are subject to
restrictions on paying dividends under state law and our revolving credit
agreement.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company, and its address is 12039 W. Alameda Parkway, Suite
Z-2, Lakewood, Colorado 80228.

NASDAQ NATIONAL MARKET LISTING

     We have applied to have our common stock approved for quotation on the
Nasdaq Stock Market's National Market, subject to official notice of issuance,
under the trading symbol "CHAP."

                        SHARES ELIGIBLE FOR FUTURE SALE

     Prior to this offering, there has been no public market for our common
stock, and there can be no assurance that a significant public market for the
common stock will develop or be sustained after this offering. Future sales of
substantial amounts of common stock, including shares issued upon exercise of
outstanding options and warrants, in the public market following this offering
could adversely affect market prices prevailing from time to time and could
impair our ability to raise capital through the sale of our equity securities.
Sales of substantial amounts of our common stock in the public market after the
restrictions lapse could adversely affect the prevailing market price and our
ability to raise equity capital in the future.

     Upon completion of this offering and based on shares outstanding at March
1, 2000, we will have outstanding           shares of common stock assuming no
exercise of the underwriters' over-allotment option and no exercise of any
outstanding options or warrants. All the shares sold in this offering, plus any
shares issued upon exercise of the underwriters' over-allotment option, will be
freely tradable without restriction under the Securities Act, unless purchased
by our "affiliates" as that term is defined in Rule 144 under the Securities
Act.

     The remaining           shares of common stock outstanding are "restricted
securities" within the meaning of Rule 144 under the Securities Act. Restricted
securities may be sold in the public market only if registered or if they
qualify for an exemption from registration under Rules 144, 144(k) or 701
promulgated under the Securities Act, which are summarized below.

     Our directors, officers and stockholders have entered into lock-up
agreements with the underwriters of this offering generally providing that they
will not offer, sell, contract to sell or grant any option to purchase or
otherwise dispose of our shares of common stock or any securities exercisable
for or convertible into our common stock owned by them prior to this offering
for a period of 180 days after the effective date of the registration statement
filed pursuant to this offering without the prior written consent of Credit
Suisse First Boston Corporation. As a result of these contractual restrictions,
notwithstanding possible earlier eligibility for sale under the provisions of
Rules 144, 144(k) and 701, shares subject to lock-up agreements may not be sold
until such agreements expire or are waived by Credit Suisse First Boston
Corporation. Taking into account the lock-up agreements, and assuming Credit
Suisse First Boston Corporation does not release stockholders from these
agreements prior to the expiration of the 180 day lock-up period, the following
shares will be eligible for sale in the public market at the following times:

     - beginning on the effective date of the registration statement, the
                 shares sold in this offering, and           additional shares,
       will be immediately available for sale in the public market;

     - beginning 180 days following the date of this prospectus,
       additional shares will become eligible for sale under Rule 144 subject to
       volume restrictions as described below; and

     - the remainder of the restricted securities will be eligible for sale from
       time to time thereafter, subject in some cases to compliance with Rule
       144.

     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned restricted
shares for at least one year, including the holding period of any prior owner
except an affiliate, would be entitled to sell within any three-month period a
number of shares that does not exceed the greater of:

     - 1% of the number of shares of common stock then outstanding, which will
       equal approximately           shares immediately after this offering; or

     - the average weekly trading volume of our common stock during the four
       calendar weeks preceding the filing of a Form 144 with respect to such
       sale.

     Sales under Rule 144 are also subject to certain manner of sale provisions
and notice requirements and to the availability of current public information
about Chaparral. Under Rule 144(k), a person who is

                                       72
<PAGE>   74

not deemed to have been our "affiliate," as defined in the Securities Act, at
any time during the three months preceding a sale, and who has beneficially
owned the shares proposed to be sold for at least two years, including the
holding period of any prior owner except an affiliate, is entitled to sell such
shares without complying with the manner of sale, public information, volume
limitation or notice provisions of Rule 144.

     Rule 701, as currently in effect, permits resales of shares in reliance
upon Rule 144 but without compliance with certain restrictions, including the
holding period requirement, of Rule 144. Any of our employees, officers,
directors or consultants who purchased shares under a written compensatory plan
or contract may be entitled to rely on the resale provisions of Rule 701. Rule
701 permits affiliates to sell their Rule 701 shares under Rule 144 without
complying with the holding period requirements of Rule 144. Rule 701 further
provides that non-affiliates may sell such shares in reliance on Rule 144
without having to comply with the holding period, public information, volume
limitation or notice provisions of Rule 144. All holders of Rule 701 shares are
required to wait until 90 days after the date of this prospectus before selling
such shares. However,           Rule 701 shares are subject to lock-up
agreements and will only become eligible for sale at the earlier of the
expiration of the 180-day lock-up agreements or no sooner than 90 days after the
offering upon obtaining the prior written consent of Credit Suisse First Boston
Corporation.

     Following the effectiveness of this offering, we intend to file a
registration statement on Form S-8 registering           shares of common stock,
the shares of common stock reserved for issuance under our 1998 stock option
plan, the 2000 equity incentive plan and the 2000 employee stock purchase plan.
Upon the filing of the registration statement on Form S-8, common stock issued
upon exercise of outstanding vested options or issued under our purchase plan,
other than common stock issued to our affiliates, will be available for
immediate resale in the open market.

</TABLE>

     The underwriting agreement provides that the underwriters are obligated to
purchase all the shares of common stock in the offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults, the
purchase commitments of non-defaulting underwriters may be increased or the
offering of common stock may be terminated.

     We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to        additional shares at the initial public offering price
less the underwriting discounts and commissions. The option may be exercised
only to cover any over-allotments of common stock.

     The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a concession of $   per share. The underwriters
and selling group members may allow a discount of $   per share on sales to
other broker/dealers. After the initial public offering, the public offering
price and concession and discount to broker/dealers may be changed by the
representatives.

will pay.

     The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the shares of common stock being offered.

     We have agreed that we will not offer, sell, contract to sell, announce our
intention to sell, pledge or otherwise dispose of, directly or indirectly, or
file with the Securities and Exchange Commission a registration statement under
the Securities Act relating to, any shares of common stock or securities
convertible into or exchangeable or exercisable for any common stock, or
publicly disclose the intention to make an offer, sale, pledge, disposition or
filing, without the prior written consent of Credit Suisse First Boston
Corporation for a period of 180 days after the date of this prospectus.

     Our officers and directors and all of our security holders have agreed that
they will not offer, sell, contract to sell, pledge or otherwise dispose of,
directly or indirectly, any shares of our common stock or securities convertible
into or exchangeable or exercisable for any shares of our common stock, enter
into a transaction which would have the same effect, or enter into any swap,
hedge or other arrangement that
                                       74
<PAGE>   76

transfers, in whole or in part, any of the economic consequences of ownership of
our common stock, whether any such aforementioned transaction is to be settled
by delivery of our common stock or such other securities, in cash or otherwise,
or publicly disclose the intention to make any such offer, sale, pledge or
disposition, or to enter into any such transaction, swap, hedge or other
arrangement, without, in each case, the prior written consent of Credit Suisse
First Boston Corporation for a period of 180 days after the date of this
prospectus.

     The underwriters have reserved for sale, at the initial public offering
price, up to    shares of the common stock for employees, directors and certain
other persons associated with us who have expressed an interest in purchasing
common stock in this offering. The number of shares available for sale to the
general public in this offering will be reduced to the extent these persons
purchase the reserved shares. Any reserved shares not so purchased will be
offered by the underwriters to the general public on the same terms as the other
shares.

     We have agreed to indemnify the underwriters against liabilities under the
Securities Act, or contribute to payments that the underwriters may be required
to make in that respect.

     We have applied to list the shares of common stock on The Nasdaq Stock
Market's National Market subject to official notice of issuance, under the
symbol "CHAP."

     Prior to this offering, there has been no public market for our common
stock. The initial public offering price will be determined by negotiation
between us and the underwriters. The principal factors to be considered in
determining the public offering price include:

     - the information in this prospectus and otherwise available to the
       underwriters;

     - the history and the prospects for the industry in which we compete;

     - the ability of our management;

     - the prospects for our future earnings;

     - the present state of our development and our current financial condition;

     - the general condition of the securities markets at the time of this
       offering; and

     - the recent market prices of, and the demand for, publicly traded common
       stock of generally comparable companies.

     The underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act of 1934, as amended.

     - Over-allotment involves syndicate sales in excess of the offering size,
       which creates a syndicate short position.

     - Stabilizing transactions permit bids to purchase the underlying security
       so long as the stabilizing bids do not exceed a specified maximum.

     - Syndicate covering transactions involve purchases of the common stock in
       the open market after the distribution has been completed in order to
       cover syndicate short positions.

     - Penalty bids permit the representatives to reclaim a selling concession
       from a syndicate member when the common stock originally sold by the
       syndicate member is purchased in a syndicate covering transaction to
       cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids
may cause the price of the common stock to be higher than it would otherwise be
in the absence of these transactions. These transactions may be effected on The
Nasdaq Stock Market's National Market or otherwise and, if commenced, may be
discontinued at any time.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are effected. Accordingly, any resale of the common stock
in Canada must be made in accordance with applicable securities laws, which will
vary depending on the relevant jurisdiction, and which may require resales to be
made in accordance with available statutory exemptions or pursuant to a
discretionary exemption granted by the applicable Canadian securities regulatory
authority. Purchasers are advised to seek legal advice prior to any resale of
the common stock.

REPRESENTATIONS OF PURCHASERS

     Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom such
purchase confirmation is received that (i) such purchaser is entitled under
applicable provincial securities laws to purchase the common stock without the
benefit of a prospectus qualified under the securities laws; (ii) where required
by law, that such purchaser is purchasing as principal and not as agent; and
(iii) such purchaser has reviewed the text above under "Resale Restrictions."

RIGHTS OF ACTION (ONTARIO PURCHASERS)

     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

ENFORCEMENT OF LEGAL RIGHTS

     All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Canadian purchasers to effect service of process within Canada upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against the issuer or such persons in Canada
or to enforce a judgment obtained in Canadian courts against the issuer or
persons outside of Canada.

NOTICE TO BRITISH COLUMBIA RESIDENTS

     A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that the purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by such purchaser in this offering. Such report must be in
the form attached to British Columbia Securities Commission Blanket Order BOR
#95/17, a copy of which may be obtained from us. Only one such report must be
filed in respect of common stock acquired on the same date and under the same
prospectus exemption.

TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of common stock should consult with their own legal and
tax advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and with respect to the eligibility of
the common stock for investment by the purchaser under relevant Canadian
legislation.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
Chaparral Network Storage, Inc.:

     We have audited the accompanying balance sheets of Chaparral Network
Storage, Inc. (formerly Chaparral Technologies, Inc.) (Company) as of March 31,
1998 and 1999, and the related statements of operations, stockholders' equity
(deficit) and cash flows for the period from inception (January 22, 1998) to
March 31, 1998 and the year ended March 31, 1999. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Chaparral Network Storage,
Inc. as of March 31, 1998 and 1999, and the results of its operations and its
cash flows for the period from inception (January 22, 1998) to March 31, 1998
and the year ended March 31, 1999, in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                            MARCH 31, 1998 AND 1999
          (INFORMATION AS OF DECEMBER 31, 1999 AND FOR THE NINE-MONTH
             PERIODS ENDED DECEMBER 31, 1998 AND 1999 IS UNAUDITED)

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  (a) ORGANIZATION AND BASIS OF FINANCIAL STATEMENT PRESENTATION

     Chaparral Network Storage, Inc. (formerly Chaparral Technologies, Inc.)
(Chaparral or the Company) was incorporated on January 22, 1998. The Company
operates in one industry segment, developing and marketing storage networking
solutions for data intensive enterprise applications.

     The accompanying unaudited financial information as of December 31, 1999
and for the nine-month periods ended December 31, 1998 and 1999 has been
prepared in accordance with generally accepted accounting principles for interim
financial information. All significant adjustments, consisting of only normal
and recurring adjustments, that, in the opinion of management, are necessary for
a fair presentation of the results of operations and cash flows for the
nine-month periods ended December 31, 1998 and 1999 have been included.
Operating results for the nine-month periods ending December 31, 1998 and 1999
are not necessarily indicative of the results that may be expected for the full
year.

  (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 revenue and expenses during the reporting
period. Actual results could differ significantly from those estimates.

  (c) CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments with maturities of
three months or less at the date of purchase to be cash equivalents.

  (d) INVENTORY

     Inventory is recorded at the lower of standard cost (which approximates
average cost) or market.

  (e) FURNITURE, FIXTURES AND EQUIPMENT

     Furniture, fixtures and equipment are recorded at cost. Depreciation and
amortization are calculated using the straight-line method over the estimated
useful lives of the assets, which are generally three years.

  (f) IMPAIRMENT OF LONG-LIVED ASSETS

     The Company accounts for long-lived assets under the provisions of
Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of
(SFAS No. 121). SFAS No. 121 requires impairment losses to be recognized on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted future cash flows estimated to be generated by those assets
are less than the assets' carrying amounts. If such assets are considered
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the asset exceeds the estimated fair value. Assets to be
disposed of are reported at the lower of the carrying value or fair value, less
costs to sell. No impairment has been recognized.

                        CHAPARRAL NETWORK STORAGE, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  (g) FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amount of certain of the Company's financial instruments,
including accounts receivable, accrued liabilities and notes receivable for
stock approximate fair value because of their short maturities.

  (h) REVENUE RECOGNITION

     Revenue from product sales is recognized upon shipment of the product to
customers. Costs of products shipped for customer evaluation are expensed at
shipment. Revenue is reduced for estimated customer returns and allowances.
Provision for estimated warranty costs, including estimated costs of support for
embedded software, is recorded at the time of sale based upon expected failure
rates and costs of repair. This provision is periodically adjusted to reflect
actual experience.

  (i) RESEARCH AND DEVELOPMENT

     Expenditures related to the development of new products and processes,
including significant improvements and refinements to existing products, are
expensed as incurred. The Company capitalizes certain software development costs
subsequent to the establishment of technological feasibility. To date, costs
incurred following technological feasibility, but prior to general release, have
been insignificant.

  (j) INCOME TAXES

     Income taxes are accounted for under the provisions of Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes (SFAS No.
109). Under SFAS No. 109, deferred income taxes are recognized for the future
tax consequences of differences between the tax bases of assets and liabilities
and their financial statement carrying amounts based on enacted tax laws and
statutory rates applicable to the periods in which the differences are expected
to affect taxable income. A valuation allowance is recorded to the extent
deferred tax assets may not be realizable.

  (k) STOCK-BASED COMPENSATION

     The Company accounts for stock-based employee compensation using the
intrinsic value based method prescribed by Accounting Principles Board Opinion
No. 25, Accounting for Stock Issued to Employees, and related interpretations
(APB No. 25). The Company provides pro forma disclosure of net loss as if the
fair value based method of accounting for the plan, as prescribed by Statement
of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation (SFAS No. 123), had been applied. Pro forma disclosures include the
effects of employee stock options granted. Equity instruments granted to
non-employees are accounted for in accordance with SFAS No. 123.

  (l) ADVERTISING COSTS

     Advertising costs are expensed as incurred. Advertising costs amounted to
$80,000 and $252,000 for the year ended March 31, 1999 and the nine-month period
ended December 31, 1999.

     In addition to its own advertising activities, the Company accrues a
percentage of sales over certain contractual minimums to reimburse distributors
for a portion of their advertising costs. Any unused allowance expires if not
used during the six months following the date of sale. Cooperative advertising
expense for the nine-month period ended December 31, 1999 totaled $37,000 and is
included in sales and marketing expense.

  (m) LOSS PER SHARE

     Loss per share is presented in accordance with the provisions of Statement
of Financial Accounting Standards No. 128, Earnings Per Share (SFAS No. 128).
Under SFAS No. 128, basic earnings (loss) per share (EPS) excludes dilution for
potential common stock and is computed by dividing income or loss
                                       F-8

                        CHAPARRAL NETWORK STORAGE, INC.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

available to common stockholders by the weighted average number of common shares
outstanding for the period. Diluted EPS reflects the potential dilution that
could occur if securities or other contracts to issue common stock were
exercised or converted into common stock. Basic and diluted EPS are the same for
all periods presented, as all potential common stock instruments are
antidilutive.

(2) INVENTORY

     The Company generally contracts for the manufacture of inventory. Certain
components are purchased by the Company and supplied to the contract
manufacturers. Inventory consists of the following:

</TABLE>

     The Company generally grants stock options with exercise prices equal to
fair value at the date of grant, and accordingly, generally does not recognize
compensation expense relating to employee option grants. In November 1999, a
total of 1,222,331 stock options were granted with exercise prices less than
fair value, resulting in total compensation expense to be recognized over the
vesting period of $2,297,982, of which $1,620,105 was recognized in the nine
months ended December 31, 1999.

     During the period from inception (January 22, 1998) to March 31, 1998, the
year ended March 31, 1999 and the nine-month period ended December 31, 1999, the
per share weighted-average fair value of stock options granted with exercise
prices equal to the fair value at the grant date was $0.05, $0.06 and $0.44,
respectively, on the date of grant using the Black Scholes option-pricing model
with the following weighted-average assumptions: no dividends; 75% volatility;
risk-free interest rate of 6.5%; and expected life of four years. If the Company
had recorded the options at the grant date under SFAS No. 123, net loss would
have been approximately $37,168, $3,765,142 and $5,305,851 and the net loss per
share would have been approximately $0, $1.43 and $.56 for the period from
inception (January 22, 1998) to March 31, 1998, the year ended March 31, 1999
and the nine-month period ended December 31, 1999, respectively.

</TABLE>

     Included in options exercisable at December 31, 1999 are 887,500 options
which were exercisable at the date of grant; however, the shares issued upon
exercise will be restricted and subject to repurchase at the exercise price if
employees terminate prior to the vesting of their shares, which is generally
over four years from the grant date of the options. At December 31, 1999,
restricted shares issued for options exercised which are subject to repurchase
totaled 3,078,244 shares, with a weighted average repurchase price of $.10. All
of the restricted shares become fully vested upon an initial public offering.

     In addition to options issued to employees and directors, the Company
issued 106,667 and 57,500 common stock options to consultants for services
during the year ended March 31, 1999 and the nine months ended December 31,
1999, respectively. These options have exercise prices ranging from $.10 to $.12
per share, are exercisable at the date of grant and expire at various dates from
November 2008 to August 2009. The fair value of these options was determined to
be $14,080 and $37,658 for the year ended March 31, 1999 and the nine months
ended December 31, 1999, respectively, and was recognized as general and
administrative expense. The fair value was calculated using the Black Scholes
option-pricing model with the following assumptions: risk-free interest rate of
6.5%; contractual lives of ten years; no dividend yield; and 75% volatility. As
of December 31, 1999, 105,000 of these options have been exercised.

  (g) WARRANTS

     In return for services performed during the nine months ended December 31,
1999, the Company granted warrants to purchase 20,000 common shares at $.01 per
share. These warrants are exercisable at any time and expire in December 2003.
The fair value of these warrants was determined to be $104,840 and was

using the Black Scholes option-pricing model with the following assumptions:
risk-free interest rate of 6.5%; contractual life of four years; no dividend
yield; and 75% volatility.

     In connection with issuances of Series A preferred stock and Series C
preferred stock, during the year ended March 31, 1999 and the nine months ended

shares of common stock, respectively, at prices ranging from $.01 to $1.30 per
share. These warrants are exercisable at any time and expire at various dates
from December 2002 to September 2003. The fair value of these warrants was
determined to be $9,883 and $134,717 for the year ended March 31, 1999 and the
nine months ended December 31, 1999, respectively, and was separately recorded
as warrants for the purchase of common stock and as a reduction to the Series A
and Series C preferred stock. The fair value was calculated using the Black
Scholes option-pricing model with the following assumptions: risk-free interest
rate of 6.5%; contractual lives of four years; no dividend yield; and 75%
volatility. As of December 31, 1999, 180,555 of these warrants have been

</TABLE>

     The Company has net operating loss carryforwards for federal income tax
purposes of approximately $3.0 million at March 31, 1999 and $6.1 million at
December 31, 1999 which is available to offset future federal taxable income, if
any, through 2019. Management believes the utilization of the carryforwards may
be limited by Internal Revenue Code Section 382 relating to changes in
ownership, as defined.

     Due to the uncertainty regarding the realization of the deferred tax assets
relating to net operating loss carryforwards and other temporary differences, a
valuation allowance has been recorded for the entire amount of the Company's
deferred tax assets.

(7) COMMITMENTS AND CONTINGENCIES

  (a) PURCHASE COMMITMENTS

     The Company generally enters into firm purchase commitments with suppliers
and third party manufacturers for its estimated inventory requirements for the

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     In accordance with the Delaware General Corporation Law, as amended (the
"DGCL"), the Registrant's certificate of incorporation, as amended, eliminates
in certain circumstances the liability of our directors for monetary damages for
breach of their fiduciary duty as directors. This provision does not eliminate
the liability of a director for: (i) a breach of the director's duty of loyalty
to the Registrant or its shareholders, (ii) acts or omissions by the director
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) a willful or negligent declaration of an unlawful distribution or
(iv) transactions from which the director derived an improper personal benefit.

     The Registrant's certificate of incorporation also provides that we shall
indemnify any person and his or her estate and personal representatives against
all liability and expenses incurred by reason of the person being or having been
a director or officer of the Registrant or, while serving as a director or
officer of the Registrant, serving at the request of it or any of its
subsidiaries as a director, an officer, an agent, an associate, an employee, a
fiduciary, a manager, a member, a partner, a promoter, or a trustee of, or to
hold any similar position with, another domestic or foreign corporation or other
entity or of an employee benefit plan, to the full extent permitted under the
DGCL. The DGCL requires a corporation to indemnify its officers and directors
against reasonable expenses incurred in any proceeding to which the officer or
director is a party and was wholly successful, on the merits or otherwise, in
defense of the proceeding. In addition to this mandatory indemnification, the
DGCL provides that a corporation may indemnify its officers and directors
against liability and reasonable expenses if the officer or director acted in
good faith and in a manner reasonably believed to be in the best interests of
the corporation in the case of conduct in an official capacity, in a manner he
or she reasonably believed was at least not opposed to the corporation's best
interests in all other cases, or in a manner he or she had no reasonable cause
to believe was unlawful in the case of criminal proceedings. In actions by or in
the name of the corporation, the DGCL provides the same standard but limits
indemnification to reasonable expenses incurred by the director and prohibits
any indemnification if the director is adjudged liable to the corporation. The
DGCL also prohibits indemnification of a director in connection with actions
charging improper personal benefit to the director if the director is adjudged
liable on that basis.

DIRECTOR AND OFFICER LIABILITY INSURANCE

     Our director and officer insurance policy indemnifies us and/or our
directors and officers for judgments and expenses arising in connection with any
claim made during the policy period for director and officer misconduct other
than dishonest or criminal acts, acts made for the director or officers's
personal profit or gain, fraudulent acts, or acts that are in violation of
Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"). The policy reimburses us when we are obligated to indemnify our directors
and officers for judgments and expenses arising from covered misconduct. The
policy reimburses the directors and officers for judgments and expenses arising
out of claims for which indemnification from us is either not available or not
permitted by law. The policy excludes coverage for claims brought by one insured
(director, officer, or the company) against another insured.

     The limit under our policy is $          and the premium is $          per
month. The deductible varies depending on whether the claim involves an
individual director or officer or the company, and on whether the claim is
related to a violation of the Exchange Act or the Securities Act of 1933, as
amended (the "Securities Act"). If the claim involves indemnifying an individual
director or officer and is not Securities related, then the deductible is $0. If
the claim involves indemnifying the company and is not Securities related, then
the deductible is $          . The deductible for any Securities related claim
is $          .

ITEM 17. UNDERTAKINGS.

     The Registrant hereby undertakes:

     The Registrant hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     The undersigned Registrant hereby undertakes that:

     - For purposes of determining any liability under the Securities, the
       information omitted from the form of prospectus filed as part of this
       registration statement in reliance upon Rule 430A and contained in a form
       of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
       or 497(h) under the Securities Act shall be deemed to be part of this
       registration statement as of the time it was declared effective.

     - For the purpose of determining any liability under the Securities, 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.

    2. DIVIDEND RIGHTS.

         2.1 Dividend Preference. In each calendar year, the holders of the then
outstanding Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock shall be entitled to receive, when, as and if declared by the
Board, out of any funds and assets of the Company legally available therefor,
noncumulative dividends at the annual Dividend Rate for each such series of
Preferred Stock, prior and in preference to the payment of any dividends or
other Distribution on the Common Stock in such calendar year (other than a
Common Stock Dividend). No dividends (other than a Common Stock Dividend) shall
be paid, and no Distribution shall be made, with respect to the Common Stock
during any calendar year unless (i) dividends in the total amount of the annual
Dividend Rate for the Series A Preferred Stock shall have first been paid or
declared and set apart for payment to the holders of the Series A Preferred
Stock, (ii) dividends in the total amount of the annual Dividend Rate for the
Series B Preferred Stock, shall have first been paid or declared and set apart
for payment to the holders of the Series B Preferred Stock and (iii) dividends
in the total amount of the Dividend Rate for the Series C Preferred Stock shall
have first been paid or declared and set apart for payment to the holders of the
Series C Preferred Stock, respectively, during that calendar year; provided,
however, that this restriction shall not apply to Permitted Repurchases.
Payments of any dividends to the holders of


                                       3
<PAGE>   5

Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
shall be paid pro rata, on an equal priority, pari passu basis according to
their respective dividend preferences as set forth herein. Dividends on the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
shall not be mandatory or cumulative, and no rights or interest shall accrue to
the holders of the Series A Preferred Stock, Series B Preferred Stock or Series
C Preferred Stock by reason of the fact that the Company shall fail to declare
or pay dividends on the Series A Preferred Stock, Series B Preferred Stock or
Series C Preferred Stock in the amount of the respective annual Dividend Rate
for each such series or in any other amount in any calendar year or any fiscal
year of the Company, whether or not the earnings of the Company in any calendar
year or fiscal year were sufficient to pay such dividends in whole or in part.

         2.2 Participation Rights. If, after dividends in the full preferential
amounts specified in this Section 2 for the Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock have been paid or declared and set
apart in any calendar year of the Company, the Board shall declare additional
dividends out of funds legally available therefor in that calendar year, then
such additional dividends shall be declared pro rata on the Common Stock, the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
on a pari passu basis according to the number of shares of Common Stock held by
such holders, where each holder of shares of Series A Preferred Stock, Series B
Preferred Stock and/or Series C Preferred Stock is to be treated for this
purpose as holding the greatest whole number of shares of Common Stock then
issuable upon conversion of all shares of Series A Preferred Stock, Series B
Preferred Stock and/or Series C Preferred Stock held by such holder pursuant to
Section 6.

         2.3 Non-Cash Dividends. Whenever a dividend or Distribution provided
for in this Section 2 shall be payable in property other than cash, the value of
such dividend or Distribution shall be deemed to be the fair market value of
such property as determined in good faith by the Board.

    3.  LIQUIDATION RIGHTS. In the event of any liquidation, dissolution or
winding up of the Company, whether voluntary or involuntary, the funds and
assets that may be legally distributed to the Company's stockholders (the
"AVAILABLE FUNDS AND ASSETS") shall be distributed to stockholders in the
following manner:

         3.1 Liquidation Preferences. The holders of each share of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock then
outstanding shall be entitled to be paid, out of the Available Funds and Assets,
and prior and in preference to any payment or distribution (or any setting apart
of any payment or distribution) of any Available Funds and Assets on any shares
of Common Stock, an amount per share equal to the Original Issue Price for each
such series of Preferred Stock, respectively, plus all declared but unpaid
dividends thereon. If upon any liquidation, dissolution or winding up of the
Company the Available Funds and Assets shall be insufficient to permit the
payment to holders of the Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock of their full preferential amounts described in this
subsection, then all the remaining Available Funds and Assets shall be
distributed among the holders of the then outstanding Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock pro rata, on an equal
priority, pari passu basis, according to their respective liquidation
preferences as set forth herein.

                                       4
<PAGE>   6

         3.2 Participation Rights. If there are any Available Funds and Assets
remaining after the payment or distribution (or the setting aside for payment or
distribution) to the holders of the Preferred Stock of their full preferential
amounts described above in this Section 3, then all such remaining Available
Funds and Assets shall be distributed among the holders of the then outstanding
Common Stock, Series A Preferred Stock, Series B Preferred Stock and Series C
Preferred Stock pro rata according to the number of shares of Common Stock held
by such holders, where, for this purpose, holders of shares of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock will be
deemed to hold (in lieu of their Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, as the case may be) the greatest whole number
of shares of Common Stock then issuable upon conversion in full of such shares
of Series A Preferred Stock, Series B Preferred Stock and Series C Preferred
Stock pursuant to Section 6.

         3.3 Merger or Sale of Assets. Each of the following shall each be
deemed to be a liquidation, dissolution or winding up of the Company as those
terms are used in this Section 3: (a) consolidation or merger of the Company
with or into any other corporation or corporations in which the holders of the
Company's outstanding shares immediately before such consolidation or merger do
not, immediately after such consolidation or merger, retain stock representing a
majority of the voting power of the surviving corporation of such consolidation
or merger; or (b) a sale of all or substantially all of the assets of the
Company.

         3.4 Non-Cash Consideration. If any assets of the Company distributed to
stockholders in connection with any liquidation, dissolution, or winding up of
the Company are other than cash, then the value of such assets shall be their
fair market value as determined by the Board, except that any securities to be
distributed to stockholders in a liquidation, dissolution, or winding up of the
Company shall be valued as follows:

            (a) The method of valuation of securities not subject to investment
letter or other similar restrictions on free marketability shall be as follows:

                (i) if the securities are then traded on a national securities
exchange or the Nasdaq National Market (or a similar national quotation system),
then the value shall be deemed to be the average of the closing prices of the
securities on such exchange or system over the 30-day period ending three (3)
days prior to the distribution;

                (ii) if actively traded over-the-counter, then the value shall
be deemed to be the average of the closing bid prices over the 30-day period
ending three (3) days prior to the distribution; and

                (iii) if there is no active public market, then the value shall
be the fair market value thereof, as determined in good faith by the Board of
Directors of the Company.

         (b) The method of valuation of securities subject to investment letter
or other restrictions on free marketability shall be to make an appropriate
discount from the market value determined as above in subparagraphs (a)(i), (ii)
or (iii) of this subsection to reflect the approximate fair market value
thereof, as determined in good faith by the Board.

                                       5
<PAGE>   7

    4. REDEMPTION. The shares of Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock are nonredeemable.

    5. VOTING RIGHTS.

        5.1 Common Stock. Each holder of shares of Common Stock shall be
entitled to one (1) vote for each share thereof held.

        5.2 Preferred Stock. Each holder of shares of Preferred Stock
shall be entitled to the number of votes equal to the number of whole shares of
Common Stock into which such shares of Preferred Stock could be converted
pursuant to the provisions of Section 6 below at the record date for the
determination of the stockholders entitled to vote on such matters or, if no
such record date is established, the date such vote is taken or any written
consent of stockholders is solicited.

        5.3 General. Subject to the foregoing provisions of this
Section 5, each holder of Preferred Stock shall have full voting rights and
powers equal to the voting rights and powers of the holders of Common Stock, and
shall be entitled to notice of any stockholders' meeting in accordance with the
Bylaws of the Company (as in effect at the time in question) and applicable law,
and shall be entitled to vote, together with the holders of Common Stock, with
respect to any question upon which holders of Common Stock have the right to
vote, except as may be otherwise provided by applicable law. Except as otherwise
expressly provided herein or as required by law, the holders of Preferred Stock
and the holders of Common Stock shall vote together and not as separate classes.

        6. CONVERSION RIGHTS. The outstanding shares of Preferred Stock shall be
convertible into Common Stock as follows:

         6.1 Optional Conversion.


            (a) At the option of the holder thereof, each share of Preferred
Stock shall be convertible, at any time or from time to time prior to the close
of business on the business day before any date fixed for redemption of such
share, into fully paid and nonassessable shares of Common Stock as provided
herein.

            (b) Each holder of Preferred Stock who elects to convert the same
into shares of Common Stock shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the Company or any transfer agent for
the Preferred Stock or Common Stock, and shall give written notice to the
Company at such office that such holder elects to convert the same and shall
state therein the number of shares of Preferred Stock being converted. Thereupon
the Company shall promptly issue and deliver at such office to such holder a
certificate or certificates for the number of shares of Common Stock to which
such holder is entitled upon such conversion. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the certificate or certificates representing the shares of
Preferred Stock to be converted, and the person entitled to receive the shares
of Common


                                       6
<PAGE>   8

Stock issuable upon such conversion shall be treated for all purposes as the
record holder of such shares of Common Stock on such date.

         6.2 Automatic Conversion.


            (a) Each share of Preferred Stock shall automatically be converted
into fully paid and nonassessable shares of Common Stock, as provided herein:
(i) immediately prior to the closing of a firm commitment underwritten public
offering pursuant to an effective registration statement filed under the
Securities Act of 1933, as amended, covering the offer and sale of Common Stock
for the account of the Company in which the aggregate public offering price
(before deduction of underwriters' discounts and commissions) equals or exceeds
$15,000,000 and the public offering price per share of which equals or exceeds
$2.20 per share before deduction of underwriters' discounts and commissions
(such price per share of Common Stock to be appropriately adjusted to reflect
Common Stock Events (as defined in subsection 6.4); or (ii) upon the Company's
receipt of the written consent of the holders of not less than two-thirds (2/3)
of the then outstanding shares of Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock to the conversion of all then outstanding
Preferred Stock under this Section 6.

            (b) Upon the occurrence of any event specified in subparagraph
6.2(a)(i) or (ii) above, the outstanding shares of Preferred Stock shall be
converted into Common Stock automatically without the need for any further
action by the holders of such shares and whether or not the certificates
representing such shares are surrendered to the Company or its transfer agent;
provided, however, that the Company shall not be obligated to issue certificates
evidencing the shares of Common Stock issuable upon such conversion unless the
certificates evidencing such shares of Preferred Stock are either delivered to
the Company or its transfer agent as provided below, or the holder notifies the
Company or its transfer agent that such certificates have been lost, stolen or
destroyed and executes an agreement satisfactory to the Company to indemnify the
Company from any loss incurred by it in connection with such certificates. Upon
the occurrence of such automatic conversion of the Preferred Stock, the holders
of Preferred Stock shall surrender the certificates representing such shares at
the office of the Company or any transfer agent for the Preferred Stock or
Common Stock. Thereupon, there shall be issued and delivered to such holder
promptly at such office and in its name as shown on such surrendered certificate
or certificates, a certificate or certificates for the number of shares of
Common Stock into which the shares of Preferred Stock surrendered were
convertible on the date on which such automatic conversion occurred.

         6.3 Conversion Price. Each share of Preferred Stock shall be
convertible in accordance with subsection 6.1 or subsection 6.2 above into the
number of shares of Common Stock which results from dividing the Original Issue
Price for such series of Preferred Stock by the conversion price for such series
of Preferred Stock that is in effect at the time of conversion (the "CONVERSION
PRICE"). The initial Conversion Price for the Series A Preferred Stock shall be
two (2) times the Original Issue Price for the Series A Preferred Stock, the
initial conversion price for the Series B Preferred Stock shall be two (2) times
the Original Issue Price of the Series B Preferred Stock and the initial
Conversion Price for the Series C Preferred Stock shall be two (2)


                                       7
<PAGE>   9

times the Original Issue Price of the Series C Preferred Stock. The Conversion
Price of each series of Preferred Stock shall be subject to adjustment from time
to time as provided below.

         6.4 Adjustment Upon Common Stock Event. Upon the happening of a Common
Stock Event (as hereinafter defined), the Conversion Price of the Series A
Preferred Stock, the Conversion Price of the Series B Preferred Stock and the
Conversion Price of the Series C Preferred Stock shall, simultaneously with the
happening of such Common Stock Event, be adjusted by multiplying the Conversion
Price of such series of Preferred Stock in effect immediately prior to such
Common Stock Event by a fraction, (a) the numerator of which shall be the number
of shares of Common Stock issued and outstanding immediately prior to such
Common Stock Event, and (b) the denominator of which shall be the number of
shares of Common Stock issued and outstanding immediately after such Common
Stock Event, and the product so obtained shall thereafter be the Conversion
Price for such series of Preferred Stock. The Conversion Price for a series of
Preferred Stock shall be readjusted in the same manner upon the happening of
each subsequent Common Stock Event. As used herein, the term "COMMON STOCK
EVENT" shall mean (a) the issue by the Company of additional shares of Common
Stock as a dividend or other distribution on outstanding Common Stock, (b) a
subdivision of the outstanding shares of Common Stock into a greater number of
shares of Common Stock, or (c) a combination of the outstanding shares of Common
Stock into a smaller number of shares of Common Stock.

         6.5 Adjustments for Other Dividends and Distributions. If at any time
or from time to time after the Original Issue Date the Company pays a dividend
or makes another distribution to the holders of the Common Stock payable in
securities of the Company other than shares of Common Stock, then in each such
event provision shall be made so that the holders of the Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock shall receive upon
conversion thereof, in addition to the number of shares of Common Stock
receivable upon conversion thereof, the amount of securities of the Company
which they would have received had their Preferred Stock been converted into
Common Stock on the date of such event (or such record date, as applicable) and
had they thereafter, during the period from the date of such event (or such
record date, as applicable) to and including the conversion date, retained such
securities receivable by them as aforesaid during such period, subject to all
other adjustments called for during such period under this Section 6 with
respect to the rights of the holders of the Preferred Stock or with respect to
such other securities by their terms.

         6.6 Adjustment for Reclassification, Exchange and Substitution. If at
any time or from time to time after the Original Issue Date the Common Stock
issuable upon the conversion of the Series A Preferred Stock, Series B Preferred
Stock and Series C Preferred Stock is changed into the same or a different
number of shares of any class or classes of stock, whether by recapitalization,
reclassification or otherwise (other than by a Common Stock Event or a stock
dividend, reorganization, merger, consolidation or sale of assets provided for
elsewhere in this Section 6), then in any such event each holder of Series A
Preferred Stock, Series B Preferred Stock or Series C


                                       8
<PAGE>   10

Preferred Stock shall have the right thereafter to convert such stock into the
kind and amount of stock and other securities and property receivable upon such
recapitalization, reclassification or other change by holders of the number of
shares of Common Stock into which such shares of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock could have been converted
immediately prior to such recapitalization, reclassification or change, all
subject to further adjustment as provided herein or with respect to such other
securities or property by the terms thereof.

         6.7 Sale of Shares Below Conversion Price.


            (a) Adjustment Formula. If at any time or from time to time after an
Original Issue Date, the Company issues or sells, or is deemed by the provisions
of this subsection 6.7 to have issued or sold, Additional Shares of Common Stock
(as defined below), otherwise than in connection with a Common Stock Event as
provided in subsection 6.4, a dividend or distribution as provided in subsection
6.5 or a recapitalization, reclassification or other change as provided in
subsection 6.6, for an Effective Price (as defined below) that is less than the
Conversion Price for such a series of Preferred Stock in effect immediately
prior to such issue or sale, then, and in each such case, the Conversion Price
for such series of Preferred Stock shall be reduced, as of the close of business
on the date of such issue or sale, to the price obtained by multiplying such
Conversion Price by a fraction:

                (i) The numerator of which shall be the sum of (A) the number of
Common Stock Equivalents Outstanding (as defined below) immediately prior to
such issue or sale of Additional Shares of Common Stock plus (B) the quotient
obtained by dividing the Aggregate Consideration Received (as defined below) by
the Company for the total number of Additional Shares of Common Stock so issued
or sold (or deemed so issued and sold) by the Conversion Price for such series
of Preferred Stock in effect immediately prior to such issue or sale; and

                (ii) The denominator of which shall be the sum of (A) the number
of Common Stock Equivalents Outstanding immediately prior to such issue or sale
plus (B) the number of Additional Shares of Common Stock so issued or sold (or
deemed so issued and sold).

            (b) Certain Definitions. For the purpose of making any adjustment
required under this subsection:

                (i) "Additional Shares of Common Stock" shall mean all shares of
Common Stock issued by the Company, whether or not subsequently reacquired or
retired by the Company, other than: (A) shares of Common Stock issued or
issuable upon conversion of the Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock; (B) the initial issuance of shares of Series
A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock or (C)
a cumulative total (since November 25, 1998) of 5,000,000 shares of Common Stock
(and/or options, warrants or rights therefor) issued to employees, officers, or
directors of, or contractors, consultants or advisers to, the Company or any
Subsidiary pursuant to incentive agreements or plans approved by the Board of
Directors of the Company (calculated net of any repurchases of such shares by
the Company and net of any such expired or terminated options, warrants or
rights and proportionally adjusted to reflect any subsequent Common Stock
Event); (D) shares of the Company's Common Stock or Preferred Stock issued in
connection with any stock split or stock dividend; (E) securities offered by the
Company to the public pursuant to a


                                       9
<PAGE>   11

registration Statement filed under the Securities Act of 1933, as amended; (F) a
cumulative total (since the Company's inception) of 125,000 shares of the
Company's Common Stock or Preferred Stock (and/or options or warrants thereof)
issued or issuable to parties providing the Company with equipment leases, real
property leases, loans, credit lines, guaranties of indebtedness, cash price
reductions or similar financing (proportionally adjusted to reflect any
subsequent Common Stock Event); or (G) securities issued pursuant to the
acquisition of another corporation or entity by the Company by consolidation,
merger, purchase of all or substantially all of the assets, or other
reorganization in which the Company acquires, in a single transaction or a
series of related transactions, all or substantially all of the assets of such
other corporation or entity or fifty (50%) or more of the voting power of such
other corporation or entity or fifty percent (50%) or more of the equity
ownership of such other entity.

                (ii) The "Aggregate Consideration Received" by the Company for
any issue or sale (or deemed issue or sale) of securities shall (A) to the
extent it consists of cash, be computed at the gross amount of cash received by
the Company before deduction of any underwriting or similar commissions,
compensation or concessions paid or allowed by the Company in connection with
such issue or sale and without deduction of any expenses payable by the Company;
(B) to the extent it consists of property other than cash, be computed at the
fair value of that property as determined in good faith by the Board; and (C) if
Additional Shares of Common Stock, Convertible Securities or Rights or Options
to purchase either Additional Shares of Common Stock or Convertible Securities
are issued or sold together with other stock or securities or other assets of
the Company for a consideration which covers both, be computed as the portion of
the consideration so received that may be reasonably determined in good faith by
the Board to be allocable to such Additional Shares of Common Stock, Convertible
Securities or Rights or Options.

                (iii) "Convertible Securities" shall mean any indebtedness or
shares of stock convertible into or exchangeable for Common Stock, including the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock.

                (iv) "Common Stock Equivalents" shall mean Convertible
Securities and rights entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock without the payment of any
consideration by such holder for such additional shares of Common Stock or
Common Stock Equivalents.

                (v) "Effective Price" of Additional Shares of Common Stock shall
mean the quotient determined by dividing the total number of Additional Shares
of Common Stock issued or sold into the Aggregate Consideration Received for the
issue of such Additional Shares of Common Stock.

                (vi) "Options" shall mean any warrants or options to subscribe
for or purchase Common Stock or Convertible Securities.

                (vii) "Rights" shall mean any right to subscribe for or purchase
Common Stock or Convertible Securities.



                                       10
<PAGE>   12

            (c) Deemed Issuances. For the purpose of making any adjustment to
the Conversion Price of the Preferred Stock required under this subsection 6.7,
if the Company issues or sells any Rights or Options or Convertible Securities
and if the Effective Price of the shares of Common Stock issuable upon exercise
of such Rights or Options and/or the conversion or exchange of Convertible
Securities (computed without reference to any additional or similar protective
or antidilution clauses) is less than the Conversion Price then in effect for a
series of Preferred Stock, then the Company shall be deemed to have issued, at
the time of the issuance of such Rights, Options or Convertible Securities, that
number of Additional Shares of Common Stock that is equal to the maximum number
of shares of Common Stock issuable upon exercise or conversion of such Rights,
Options or Convertible Securities upon their issuance and to have received, as
the Aggregate Consideration Received for the issuance of such shares, an amount
equal to the total amount of the consideration, if any, received by the Company
for the issuance of such Rights or Options or Convertible Securities, plus, in
the case of such Rights or Options, the minimum amounts of consideration, if
any, payable to the Company upon the exercise in full of such Rights or Options,
plus, in the case of Convertible Securities, the minimum amounts of
consideration, if any, payable to the Company (other than by cancellation of
liabilities or obligations evidenced by such Convertible Securities) upon the
conversion or exchange thereof; provided that:

                (i) if the minimum amounts of such consideration cannot be
ascertained, but are a function of antidilution or similar protective clauses,
then the Company shall be deemed to have received the minimum amounts of
consideration without reference to such clauses;

                (ii) if the minimum amount of consideration payable to the
Company upon the exercise of Rights or Options or the conversion or exchange of
Convertible Securities is reduced over time or upon the occurrence or
non-occurrence of specified events other than by reason of antidilution or
similar protective adjustments, then the Effective Price shall be recalculated
using the figure to which such minimum amount of consideration is reduced; and

                (iii) if the minimum amount of consideration payable to the
Company upon the exercise of such Rights or Options or the conversion or
exchange of Convertible Securities is subsequently increased, then the Effective
Price shall again be recalculated using the increased minimum amount of
consideration payable to the Company upon the exercise of such Rights or Options
or the conversion or exchange of such Convertible Securities.

No further adjustment of the Conversion Price, adjusted upon the issuance of
such Rights or Options or Convertible Securities, shall be made as a result of
the actual issuance of shares of Common Stock on the exercise of any such Rights
or Options or the conversion or exchange of any such Convertible Securities. If
any such Rights or Options or the conversion rights represented by any such
Convertible Securities shall expire without having been fully exercised, then
the Conversion Price as adjusted upon the issuance of such Rights or Options or
Convertible Securities shall be readjusted to the Conversion Price which would
have been in effect had an adjustment been made on the basis that the only
shares of Common Stock so issued were the shares of Common Stock, if any, that
were actually issued or sold on the exercise of such Rights

                                       11
<PAGE>   13

or Options or rights of conversion or exchange of such Convertible Securities,
and such shares of Common Stock, if any, were issued or sold for the
consideration actually received by the Company upon such exercise, plus the
consideration, if any, actually received by the Company for the granting of all
such Rights or Options, whether or not exercised, plus the consideration
received for issuing or selling all such Convertible Securities actually
converted or exchanged, plus the consideration, if any, actually received by the
Company (other than by cancellation of liabilities or obligations evidenced by
such Convertible Securities) on the conversion or exchange of such Convertible
Securities, provided that such readjustment shall not apply to prior conversions
of Preferred Stock.

         6.8 Certificate of Adjustment. In each case of an adjustment or
readjustment of the Conversion Price for a series of Preferred Stock, the
Company, at its expense, shall cause its Chief Financial Officer to compute such
adjustment or readjustment in accordance with the provisions hereof and prepare
a certificate showing such adjustment or readjustment, and shall mail such
certificate, by first class mail, postage prepaid, to each registered holder of
the Preferred Stock at the holder's address as shown in the Company's books.

         6.9 Fractional Shares. No fractional shares of Common Stock shall be
issued upon any conversion of Preferred Stock. In lieu of any fractional share
to which the holder would otherwise be entitled, the Company shall pay the
holder cash equal to the product of such fraction multiplied by the Common
Stock's fair market value as determined in good faith by the Board as of the
date of conversion.

         6.10 Reservation of Stock Issuable Upon Conversion. The Company shall
at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Preferred Stock, the
Company will take such corporate action as may, in the opinion of its counsel,
be necessary to increase its authorized but unissued shares of Common Stock to
such number of shares as shall be sufficient for such purpose.

         6.11 Notices. Any notice required by the provisions of this Section 6
to be given to the holders of shares of the Preferred Stock shall be deemed
given upon the earlier of actual receipt or deposit in the United States mail,
by certified or registered mail, return receipt requested, postage prepaid,
addressed to each holder of record at the address of such holder appearing on
the books of the Company.

         6.12 No Impairment. The Company shall not avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but shall at all times in good faith assist in
carrying out all such action as may be reasonably necessary or appropriate in
order to protect the conversion rights of the holders of the Preferred Stock
against impairment.

    7.  RESTRICTIONS AND LIMITATIONS.

        7.1 Class Protective Provisions. So long as any shares of
Preferred Stock remain outstanding, the Company shall not, without the approval,
by vote or written consent, of the holders of a majority of the Preferred Stock
then outstanding, voting as a single class:

            (a) amend its Certificate of Incorporation in any manner that would
alter or change any of the rights, preferences, privileges or restrictions of
the Preferred Stock;

            (b) amend its Certificate of Incorporation or Bylaws in any other
manner that would adversely affect the rights, preferences and privileges of the
Preferred Stock;

            (c) reclassify any outstanding shares of securities of the Company
into shares having rights, preferences or privileges senior to or on a parity
with the Preferred Stock; or

            (d) authorize or issue any other stock having rights or preferences
senior to or on a parity with the Preferred Stock as to dividend rights or
liquidation preferences.

writing, setting forth the action so taken, shall be signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. Prompt notice of the taking of
the corporate action without a meeting by less than unanimous written consent
shall be given to those stockholders who have not consented in writing.

         9. List of Stockholders. The officer who has charge of the stock ledger

earlier resignation or removal. No decrease in the number of directors shall
have the effect of shortening the term of any incumbent director.

created directorships resulting from any increase in the authorized number of
directors elected by all of the stockholders having the right to vote as a
single class shall be filled solely by a majority of


                                       3
<PAGE>   4


the directors then in office, although less than a quorum, or by a sole
remaining director. Any directors so chosen shall hold office until the next
annual stockholders meeting and until their successors shall be elected and
qualified. No decrease in the number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.

            If at any time of filling any vacancy or newly created directorship,
the directors then in office shall constitute less than a majority of the whole
board, the Court of Chancery may, upon application of any stockholders or
stockholders holding at least ten percent (10%) of the total number of shares at
the time outstanding having the right to vote for such directors, summarily
order an election to be held to fill any such vacancies or newly created
directorships, or to replace the directors chosen by the directors then in
office as aforesaid, which election shall be governed by Section 211 of the
General Corporation Law of Delaware.

            Any director may resign at any time by giving written notice to the
CEO or to the secretary of the Corporation. Such resignation shall take effect
at the future time specified therein; and unless otherwise specified therein,
the acceptance of such resignation shall not be necessary to make it effective.
Any vacancy occurring on the Board of Directors created by the resignation of a
director may be filled by the affirmative vote of a majority of directors then
in office, including those who have so resigned. The vote thereon shall take
effect when such resignation or resignations shall become effective. A director
elected to fill a vacancy shall be elected for the unexpired term of his
predecessor in office.

         3. Compensation. Any director may be paid any one or more of the
following: his expenses, if any, of attendance at meetings; a fixed sum for
attendance at each meeting; or a stated salary as director. No such payment
shall preclude any director from serving the Corporation in any other capacity
and receiving compensation therefor. A director shall also be entitled to
receive options for the acquisition of shares of stock of the Corporation.

                                    ACTION V

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

         2. Regular Meetings. The Board of Directors shall meet each year
immediately after the annual meeting of the stockholders for the purpose of
electing officers and transacting such other business as may come before the
meeting. The Board of Directors or any committee designated by the board may
provide, by resolution, for the holding of additional regular meetings without
other notice than such resolution.

         3. Special Meetings. Special meetings of the Board of Directors or any
committee designated by the board may be called at any time by the chairman of
the board, if any, by the


                                       4
<PAGE>   5


CEO or by a majority of the members of the Board of Directors or any such
committee, as the case may be.

         4. Notice of Meetings. Notice of the regular meetings of the Board of
Directors or any committee designated by the board need not be given. Except as
otherwise provided by these Bylaws or the laws of the State of Delaware, written
notice of each special meeting of the Board of Directors or any such committee
setting forth the time and the place of the meeting shall be given to each
director not less than two (2) days prior to the time fixed for the meeting.
Notice of special meetings may be either given personally, personally by
telephone, or by sending a copy of the notice through the United States mail or
facsimile, or by telegram, charges prepaid, to the address of each director
appearing on the books of the Corporation, If mailed, such notice shall be
deemed to be delivered when deposited in the United States mail so addressed,
with postage prepaid thereon. If notice is given by facsimile, such notice shall
be deemed to be delivered upon transmission of the facsimile. If notice is given
by telegram, such notice shall be deemed to be delivered when the telegram is
delivered when the telegram is delivered to the telegraph operator. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the Board of Directors need be specified in the notice or waiver of notice of
such meeting.

         5. Waiver of Notice. A director may in writing waive notice of any
special meeting of the Board of Directors or any committee, either before, at,
or after the meeting; and his waiver shall be deemed the equivalent of giving
notice. Attendance of a director at a meeting shall constitute waiver of notice
of that meeting unless he attends for the express purpose of objecting to the
transaction of business because the meeting has not been lawfully called or
convened.

         6. Quorum. At meeting of the Board of Directors or any committee
designated by the board a majority of the number of directors fixed by these
Bylaws or a majority of the members of any such committee, as the case may be,
shall be necessary to constitute a quorum for the transaction of business. If a
quorum is present, the act of the majority of directors in attendance shall be
the act of the Board of Directors or any such committee, as the case may be,
unless the act of a greater number is required by these Bylaws, the Certificate
of Incorporation or the General Corporation Law of Delaware. One or more
directors may participate in meetings of the Board of Directors as authorized by
Subparagraph 11 of the Article IV by conference telephone, while the remaining
director or directors are physically present at the meeting.

         7. Presumption of Assent. A director who is present at a meeting of the
board or committee designated by the board when corporate action is taken is
deemed to have assented to the action taken unless: (i) he/she objects in
writing at the beginning of such meeting to the holding of the meeting or the
transacting of business at the meeting; (ii) he/she contemporaneously requests
that his or her dissent from the action taken be entered in the minutes of such
meeting; or (iii) he/she gives written notice of his or her dissent to the
presiding officer of such meeting before its adjournment or to the secretary of
the Corporation immediately after adjournment of such meeting. The right of
dissent as to a specific action taken in a meeting of a board or committee
thereof is not available to a director who votes in favor of such action.

         8. Reliance on Books of Account or Reports. Any member of the Board of
Directors or any committee designated by the Board of Directors shall, in the
performance of his duties, be fully protected in relying in good faith upon the
records of the Corporation and upon such information, opinions, reports or
statements presented to the Corporation by any of its officers, or employees, or
committees of the Board of Directors, or by any other person as to matters the

majority of the whole board designate one or more committees, each committee to
consist of one or more directors of the Corporation. The board may designate one
or more directors as alternate members of any committee who may replace any
absent or disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members present at
any meeting and not disqualified from voting, whether or not he/she or they
constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any such absent or disqualified
member. Any such committee to the extent provided in the resolution of the Board
of Directors shall have and may exercise all of the powers and authority of the
Board of Directors in the management of the business and affairs of the
Corporation and may authorize the seal of the Corporation to be affixed to all
papers which it may acquire. No such committee shall have the power or authority
of the Board of Directors to: (i) amend the Certificate of Incorporation; (ii)
adopt an agreement of merger or consolidation; (iii) recommend to the
stockholders the sale, lease or exchange of all or substantially all of the
Corporation's property and assets; (iv) recommend to the stockholders a
dissolution of the Corporation or a revocation of a dissolution; (v) amend the
Bylaws of the Corporation; (vi) or unless expressly provided for by resolution,
or in the Certificate of Incorporation, declare a dividend, authorize the
issuance of stock or to adopt a certificate of ownership and merger. To the
extent authorized by resolution or resolutions providing for the issuance of
shares of stock, adopted by the board, a committee may: (i) fix the designations
and any of the preferences or rights of such shares relating to dividends,
redemption, dissolution, any distribution of assets of the Corporation or the
conversion into, or the exchange of such shares for, shares of any other class
or classes or any other series of the same or any other class or classes of
stock of the Corporation; or (ii) fix the number of shares of any series of
stock or authorize the increase or decrease of the shares of any series. If any
such delegation of the authority of the Board of Directors is made as provided
herein, all references to the Board of Directors contained in these Bylaws, the
Certificate of Incorporation, the General Corporation Law of Delaware or any
other applicable law or regulation relating to the authority so delegated shall
be deemed to refer to such committee.

         10. Informal Action by Directors. Any action required or permitted to
be taken at a meeting of the Board of Directors or any committee thereof, may be
taken without a meeting if all the members of the board or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the board or committee. Such consent shall
have the same force and effect as a unanimous vote of the directors and my be
stated as such in any articles or documents filed with the Secretary of State of
Delaware under the General Corporation Law of Delaware.


                                       6

committee designated by the board may participate in meeting of such board or
committee by means of a conference telephone or similar communications equipment
by which all persons participating in the meeting can hear each other at the
same time. Participation in such meeting shall constitute presence in person at
the meeting.

                                  ARTICLE VIII
                       INDEMNIFICATION OF CERTAIN PERSONS

         1. Indemnification. For purposes of Article VIII, a "Proper Person"
means any person (including the estate or personal representative of a director)
to the fullest extent permitted by Section 145 of the Delaware General
Corporation Law, who was or is a party or is threatened to be made a party to
any threatened, pending, or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, and whether formal or informal, by
reason of the fact that he/she is or was a director, officer, employee,
fiduciary or agent of the corporation, or is or was serving at the request of
the corporation as a director, officer, partner, trustee, employee, fiduciary or
agent of any foreign of domestic profit or nonprofit corporation or of any
partnership, joint venture, trust, profit or nonprofit unincorporated
association, limited liability company, or other enterprise or employee benefit
plan. The corporation shall indemnify any Proper Person against reasonably
incurred expenses (including attorneys' fees), judgments, penalties, fines
(including any excise tax assessed with respect to an employee benefit plan) and
amounts paid in settlement reasonably incurred by him in connection with such
action, suit or proceeding if it is determined by the groups set forth in
Section 4 of this Article that he/ she conducted himself in good faith and that
he/she reasonably believed (i) in the case of conduct in his official capacity
with the corporation, that his conduct was in the corporation's best interests,
or (ii) in all other cases (except criminal cases), that his


                                       8
<PAGE>   9


conduct was at least not opposed to the corporation's best interests, or (iii)
in the case of any criminal proceeding, that he/she had no reasonable cause to
believe his conduct was unlawful. Official capacity means, when used with
respect to a director, the office of director and, when used with respect to any
other Proper Person, the office in a corporation held by the officer or the
employment, fiduciary or agency relationship undertaken by the employee,
fiduciary, or agent on behalf of the corporation. Official capacity does not
include service for any other domestic or foreign corporation or other person or
employee benefit plan. A director shall not be liable to the corporation or its
shareholders for any action he/she takes or omits to take as a director if, in
connection with such action or omission, he/she performs his duties in
compliance with this section.

         A director's conduct with respect to an employee benefit plan for a
purpose the director reasonably believed to be in the interests of the
participants in or beneficiaries of the plan is conduct that satisfies the
requirement in the Section 1. A director's conduct with respect to an employee
benefit plan for a purpose that the director did not reasonably believe to be in
the interests of the participants in or beneficiaries of the plan shall be
deemed not to satisfy the requirement of this section that he/she conduct
himself in good faith.

         No indemnification shall be made under this Article VIII to a Proper
Person with respect to any claim, issue or matter in connection with a
proceeding by or in the right of a corporation in which the Proper Person was
adjudged liable to the corporation or in connection with any proceeding charging
that the Proper Person derived an improper personal benefit, whether or not
involving action in an official capacity, in which he/she was adjudged liable on
the basis that he/she derived an improper personal benefit. Further,
indemnification under this section in connection with proceeding brought by or
in the right of the corporation shall be limited to reasonable expenses,
including attorneys' fees, incurred in connection with the proceeding.

         2. Right to Indemnification. The corporation shall indemnify any Proper
Person who was wholly successful, on the merits or otherwise, in defense of any
action, suit or proceeding as to which he/she was entitled to indemnification
under Section 1 of this Article VIII against expenses (including attorneys'
fees) reasonably incurred by him in connection with the proceeding without the
necessity of any action by the corporation other than the determination in good
faith that the defense has been wholly successful.

         3. Effect of Termination of Action. The termination of any action, suit
or proceeding by judgment, order settlement or conviction, or upon a plea of
nolo contendere or its equivalent shall not of itself create a presumption that
the person seeking indemnification did not meet the standards of conduct
described in Section 1 of this Article VIII. Entry of a judgment by consent as
part of a settlement shall not be deemed an adjudication of liability, as
described in Section 2 of this Article VIII.

         4. Groups Authorized to Make Indemnification Determination. Except
where there is a right to indemnification as set forth in Sections 1 or 2 of
this Article VIII or where indemnification is ordered by a court in Section 5,
any indemnification shall be made by the corporation only as determined in the
specific case by a proper group that indemnification of the Proper Person is
permissible under the circumstances because he/she has met the applicable


                                       9
<PAGE>   10


standards of conduct set forth in Section 1 of this Article. This determination
shall be made by the Board of Directors by a majority vote of those present at a
meeting who are not parties to the proceeding at which a quorum is present,
whish quorum shall consist of directors not parties to the proceeding
("Quorum"). If a Quorum cannot be obtained the determination shall be made by a
majority vote of a committee of the Board of two or more directors not parties
to the proceeding. If a Quorum of the Board of Directors cannot be obtained and
the committee cannot be established, or even if a Quorum is obtained or the
committee is designated and a majority of the directors constituting such Quorum
or committee so directs, the determination shall be made by (i) independent
legal counsel selected by a vote of the Board of Directors or the committee in
the manner specified in this Section 4 or, if a Quorum of the full Board of
Directors cannot be obtained and a committee cannot be established, by
independent legal counsel selected by a majority vote of the full Board
(*including directors who are parties to the action) or (ii) a vote of the
shareholders.

         Authorization of indemnification and advance of expenses shall be made
in the same manner as the determination that indemnification or advance of
expenses is permissible except that, if the determination that indemnification
or advance of expenses is permissible is made by independent legal counsel,
authorization of indemnification and advance of expenses shall be made by the
body that selected such counsel.

         5. Court-Ordered or Arbitrator-Ordered Indemnification. Any Proper
Person may apply for indemnification to the court conducting the proceeding or
to another court of competent jurisdiction or pursuant to Chaparral's
Arbitration Policy, for mandatory indemnification under Section 2 of this
Article, including indemnification for reasonable expenses incurred to obtain
court-ordered indemnification. If a court or arbitrator determines that the
Proper Person is entitled to indemnification under Section 2 of this Article
VIII, the court or arbitrator shall order indemnification, including the Proper
Persons' reasonable expenses incurred to obtain court-ordered or
arbitrator-ordered indemnification. If the court or arbitrator determines that
such Proper Person is fairly and reasonably entitled to indemnification in view
of all the relevant circumstances, whether or not he/she met the standards of
conduct set forth in Section 1 of this Article VIII or was adjudged liable in
the proceeding, the court or arbitrator may order such indemnification as the
court or arbitrator deems proper except that if the Proper Person has been
adjudged liable, indemnification shall be limited to reasonable expense incurred
in connection with the proceeding and reasonable expenses incurred to obtain
court-ordered or arbitrator-ordered indemnification.

         6. Advance of Expenses. Reasonable expenses (including attorneys' fees)
incurred in defending an action, suit or proceeding as described in Section 1
may be paid by the corporation to any Proper Person in advance of the final
disposition of such action, suit or proceeding upon receipt of (i) a written
affirmation of such Proper Person's good faith belief that he/she has met the
standards of conduct prescribed by Section 1 of this Article VIII, (ii) a
written undertaking, executed personally or on the Proper Person's behalf, to
repay such advances if it is ultimately determined that he/she did not meet the
prescribed standards of conduct (the undertaking shall be an unlimited general
obligation of the Proper Person but need not be secured if the corporation
determines that the Proper Person has the financial ability to make repayment),
and (iii) a determination is made by the proper group (as described in Section 4
of


                                       10
<PAGE>   11


Determination and authorization of payments shall be made in the same manner
specified in Section 4 of this Article VIII.

         7. Additional Indemnification to Certain Persons Other Than Directors.
In addition to the indemnification provided to officers, employees, fiduciaries
or agents because of their status as Proper Persons under this Article, the
corporation may also indemnify and advance expenses to them if they are not
directors of the corporation to a greater extent than is provided in these
bylaws, if not inconsistent with public policy, provided that such
indemnification is approved by general or specific action of its board of
directors or shareholders, or by contract approved by the board of directors.

         8. Witness Expenses. The sections of this Article VIII do not limit the
corporation's authority to pay or reimburse expenses incurred by a director in
connection with an appearance as a witness in proceeding at a time when he/she
has not been named as a defendant or respondent in the proceeding.

         9. Report to Shareholders. Any indemnification of or advance of
expenses to a director in accordance with this Article VIII, if arising out of a
proceeding by or on behalf of the corporation, shall be reported in writing to
the shareholders with or before the notice of the next shareholders' meeting. If
the next shareholder action is taken without a meeting at the instigation of the
Board of Directors, such notice shall be given to the shareholders at or before
the time the first shareholder signs a writing consenting to such action.

                                   ARTICLE IX
                                CORPORATE RECORDS

         1. General. Any stockholder of record, in person or by attorney or
other agent, shall, upon written demand under oath stating the purpose the
Corporation's stock ledger, a list of its stockholders, and its other books and
records, and to make copies or extracts therefrom. A proper purpose shall mean a
purpose reasonable related to such person's interest as a stockholder. In every
instance where an attorney or other agent shall be the person who seeks the
right to inspection, the demand under oath shall be accompanied by a power of
attorney or such other writing which authorizes the attorney or other agent to
so act on behalf of the stockholder. The demand under oath shall be directed to
the Corporation at its registered office in this state or at its principal place
of business.

                                    ARTICLE X
                       STOCK CERTIFICATES, DIVIDENDS, ETC.

         1. General. The stock certificates of the Corporation shall be numbered

authorized to sign stock certificates.

         2. Transfers. Transfers of shares shall be made on the books of the
Corporation upon surrender of the certificates therefor, endorsed by the person
named in the certificate or by


                                       11
<PAGE>   12


attorney, lawfully constituted in writing. No transfer shall be made which is
inconsistent with law.

         3. Lost Certificates. The Corporation may issue a new certificate of
stock in the place of any certificate theretofore signed by it, alleged to have
been lost, stolen or destroyed, and the Corporation may require the owner of the
lost, stolen or destroyed certificate, or his legal representative to five the
Corporation a bond for a nominal fee sufficient to indemnify it against any
claim that may be made against it on account of the alleged loss, theft or
destruction of any such certificate or the issuance of such new certificate.

         4. Record Date. In order that the Corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or the express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights, in
respect of any change, conversion or exchange of stock or for the purpose of any
other lawful action, the Board of Directors may fix, in advance, a record date,
which shall not be more than sixty (60) nor less than ten (10) days before the
date of such meeting, nor more than sixty (60) days prior to any other action.

                  If no record date is fixed:

                  (a) The record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of

                  (c) The record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.

                  (d) A determination of stockholders of record entitled to

         5. Dividends. The Board of Directors may declare and pay dividends upon
the outstanding shares of the Corporation from time to time and to such extent
as they deem advisable, in the manner and upon the terms and conditions provided

         6. Reserves. Before payment of any dividend there may be set aside out
of the net profits of the Corporation such sum or sums as the directors, from
time to time, in their absolute discretion, think proper as a reserve fund to
meet contingencies, or for equalizing dividends, or for repairing or maintaining
any property of the Corporation, or for such other purpose as the


                                       12
<PAGE>   13


directors shall think conducive to the interests of the Corporation, and the
directors may abolish any such reserve in the manner in which it was created.

                                   ARTICLE XI
                            MISCELLANEOUS PROVISIONS

         1. Checks. All checks or demands for money and notes of the Corporation
shall be signed by such officer or officers as the Board of Directors may form
time to time designate.

         2. Fiscal Year. The fiscal year shall begin on the first day of April.

         3. Notice. Whenever written notice is required to be given to any
person, it may be given to such person, either personally or by sending a copy
thereof through the mail or by facsimile, or by telegram, charges prepaid, to
his or her address appearing on the books of the Corporation, or supplied by him
or her to the Corporation for the purpose of notice. If the notice is sent by
mail or by telegram, it shall be deemed to have been given to the person
entitled thereto when deposited in the United States mail or with a telegraph
office for transmission to such person. If the notice is sent by facsimile, such
notice shall be deemed to have been given upon successful transmission of the
facsimile. Such notice shall specify the place, day and hour of the meeting and,
in the case of a special meeting of stockholders, the general nature of the
business to be transacted.

         4. Waiver of Notice. Whenever any written notice is required by
statute, or by the Certificate of the Bylaws of this Corporation, a waiver
thereof in writing, signed by the person or persons entitled to such notice,
whether before or after the time stated therein, shall be deemed equivalent to
the giving of such notice. Except in the case of a special meeting of
stockholders, neither the business to be transacted at nor the purpose of the
meeting need be specified in the waiver of notice of such meeting. Attendance of
a person either in person or by proxy, at any meeting shall constitute a waiver
of notice of such meeting, except where a person attends a meeting for the
express purpose of objecting to the transaction of any business because the
meeting was not lawfully called or convened.

         5. Disallowed Compensation. Any payments made to an officer or employee
of the Corporation such as a salary, commission, bonus, interest, rent, travel
or entertainment expense incurred by him, which shall be disallowed in whole or
in part as a deductible expense by the Internal Revenue Service, shall be
reimbursed by such officer or employee to the Corporation to the full extent of
such disallowance. It shall be the duty of the directors, as a Board, to enforce
payment of each such amount disallowed. In lieu of payment by the officer or
employee, subject to the determination of the directors, proportionate amounts
may be withheld from his or her future compensation payments until the amount
owed to the Corporation has been recovered.

         6. Resignations. Any director or other officer may resign at anytime,
such resignation to be in writing, and to take effect from the time of its
receipt by the Corporation, unless some time be fixed in the resignation and
then from that date. The acceptance of a resignation shall not be required to
make it effective.

                  Re:   Sale of _____ Shares of Common Stock on
                        Registration Statement on Form S-1
                        Registration No. 333-

Dear Ladies and Gentlemen:

             We are counsel to Chaparral Network Storage, Inc.. (the "Company")
and are providing this opinion in connection with the registration by the
Company of ______ shares of Common Stock (the "Shares") described in the
Company's Registration Statement on Form S-1 Registration No. 333-______, as
filed with the Securities and Exchange Commission on March __, 2000 (the
"Registration Statement"). In such connection we have examined certain corporate
records and proceedings of the Company, including actions taken by the Company
in respect of the authorization and issuance of the Shares, and such other
matters as we deemed appropriate.

             Based on the foregoing, we are of the opinion that the Shares have
been duly authorized and, when sold as contemplated in the Registration
Statement, will be legally issued, fully paid and non-assessable.

             We hereby consent to the reference to this firm under the heading
"Legal Matters" in the Registration Statement, and in the Prospectus
constituting a part thereof, as the counsel who will pass upon the validity of
the Shares.

                                              Very truly yours,

                                                                    EXHIBIT 10.1
[CHAPARRAL NETWORK STORAGE, INC. LOGO]

                             1998 STOCK OPTION PLAN
                            (Effective June 1, 1999)

         1. Purpose.

            (a) The purpose of the CHAPARRAL NETWORK STORAGE, INC. [formerly
         Chaparral Technologies, Inc.] 1998 Stock Option Plan (the "Plan") is to
         provide a means whereby selected eligible employees and officers and
         directors of, and consultants to, CHAPARRAL NETWORK STORAGE, INC., a
         Delaware Corporation (the "Company"), and its Affiliates, if any, as
         defined below, may be given a favorable opportunity to acquire common
         stock of the Company (the "Common Stock"), thereby encouraging such
         persons to accept or continue a qualifying relationship with the
         Company, increasing the interest of such persons in the Company's
         welfare through participation in the growth and the value of the Common
         Stock; and furnishing such persons with an incentive to improve
         operations and increase profits of the Company. The terms "Affiliate"
         or "Affiliates" as used in the Plan shall mean any parent corporation
         or subsidiary corporation of the Company, as those terms are defined in
         Sections 424(e) and (f) of the Internal Revenue Code of 1986, as
         amended (the "Code).

            (b) To accomplish the foregoing objectives, this Plan provides a
         means whereby employees, directors, and consultants may receive options
         to purchase Common Stock.

         2. Stock Options. Stock options granted pursuant to the Plan may, at
the discretion of the Board of Directors of the Company, be granted either as an
Incentive Stock Option ("ISO") or a Non-statutory Stock Option ("NSO").

         3. Administration. The Board of Directors (the "Board") whose authority
shall be plenary, shall administer the Plan, unless and until such time as the
Board delegates administration of the Plan pursuant to subsection 3(b) below.

            (a) The Board, whose determinations shall be conclusive, shall have
         the power, subject to and within the limits of the express provisions
         of the Plan:

                (i) To grant options pursuant to the Plan.

                (ii) To determine from time to time which of the eligible
            persons described in Section 5 below shall be granted options under
            the Plan, the number of shares for which each option shall be
            granted, the term of each granted option and the time or times
            during the term of each option within which all or portions of each
            option may be accelerated, if allowed under applicable law.

                (iii) To construe and interpret the Plan and options granted
            under it and to establish, amend, and revoke rules and regulations
            for its administration. The Board, in the exercise of this power,
            shall generally determine all questions of policy and expediency
            that may arise and may correct any defect, omission of inconsistency
            in the Plan or in any option agreement with respect to the Plan in a
            manner to the extent it shall deem necessary or expedient to make
            the Plan fully effective.

                (iv) To grant options in exchange for cancellation of options
            granted earlier at different exercise prices; provided, however,
            nothing contained herein shall empower the Board to grant an ISO
            under conditions or pursuant to terms that are inconsistent with the
            requirements of subsection 4(b), below, or Section 422 of the Code.

                (v) To prescribe the terms and provisions of each option granted
            which need not be identical and the form of written instrument that
            shall constitute the option agreement.

                (vi) To amend the Plan as provided in Section 11, below.

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

                                  CONFIDENTIAL                       PAGE 1 OF 6
<PAGE>   2


                (viii) To take appropriate action to cause any option granted
            hereunder to cease to be an ISO, provided, however, no such action
            may be taken by the Board without the written consent of the
            affected optionee.

            (b) The Board may, however, by resolution, delegate administration
         of the Plan (including, without limitation, the Board's powers under
         subsection 3(a) above) to a committee acting under the authority of the
         Board. The Board shall have complete discretion to determine the
         composition, structure, form, term and operation of any committee
         established to administer the Plan. The Board at any time may revest in
         the Board the administration of the Plan.

         4. Shares Subject to Plan and to Option.

            (a) Subject to the provisions of Section 10 below (relating to
         adjustments upon changes in stock), the stock which may be sold
         pursuant to options granted under the Plan shall not exceed in the
         aggregate of twenty-eight million (28,000,000) shares of the Company's
         authorized Common Stock and may be unissued shares, reacquired shares,
         or shares bought on the market for the purpose of issuance under the
         Plan. If any options granted under the Plan shall for any reason
         terminate or expire without having been exercised in full, the stock
         not purchased under such options shall be available again for the
         purpose of the Plan.

            (b) If the aggregate fair market value of stock with respect to
         which ISOs are exercisable for the first time by an individual during
         any calendar year exceeds the amount of the annual limitation provided
         in Section 422(d) of the Code, the excess shall be deemed to be a grant
         of an NSO to the extent of such excess.

         5. Eligibility

            (a) All employees of the Company and its Affiliates are eligible to
         receive ISOs and only employees of the Company and its Affiliates may
         be granted ISOs. Employees, directors and independent contractors shall
         also be eligible for NSOs.

            (b) No option issued under the Plan may be granted to a person who,
         at the time such option would be granted, owns stock possessing more
         than ten percent (10%) of the total combined voting power of all
         classes of outstanding capital stock of the Company or its Affiliate
         unless the option price is at least one hundred percent (100%) in the
         case of an NSO, one hundred ten percent (110%) in the case of an ISO,
         of the fair market value of the stock subject to the option and the ISO
         option by its terms is not exercisable after five (5) years from the
         date such option is granted. Any employee may hold more than one (1)
         option at any time. For purposes of this subsection 5(b), in
         determining stock ownership, an optionee shall be considered as owning
         the voting capital stock owned, directly or indirectly, by or for his
         brothers and sisters, spouse, ancestors and lineal descendants. Voting
         capital stock owned, directly or indirectly, by or for a corporation,
         partnership, estate or trust shall be considered as being owned
         proportionately by or for its shareholders, partners or beneficiaries,
         as applicable. Common Stock with respect to which any such optionee
         holds an option shall not be counted. Additionally, for purposes of
         this subsection 5(b), outstanding capital stock shall include all
         capital stock actually issued and outstanding immediately after the
         grant of the option to the optionee. Outstanding capital stock shall
         not include capital stock authorized for issue under outstanding
         options held by the optionee or by any other person.

         6. Terms of Options. Options granted pursuant to the Plan need not be
identical, but each option shall be granted within ten (10) years from the date
the Plan is adopted by the Board or approved by the shareholders, whichever is
earlier, shall specify the number of shares to which it pertains and shall be
subject to the following terms and conditions:

            (a) The purchase price of each option shall be determined by the
         administrator of the Plan at the time the option is granted, but shall
         in no event, except as otherwise set forth in Section 5 above, be less
         than eighty-five percent (85%) in the case of an NSO, or one hundred
         percent (100%) in the case of an ISO, of the fair market value of the
         stock subject to the option on the date the option is granted. For all
         purposes of the Plan, the fair market value of the Common Stock shall
         be, if the Stock is publicly traded, its closing bid price on NASDAQ or
         the over-the-counter market, or if it is traded on another stock
         exchange, the last price at which it is traded on the exchange. If the
         stock is not publicly traded, the fair market value shall be such value
         as is determined in good faith by the Board of Directors by taking into

                                  CONFIDENTIAL                       PAGE 2 OF 6

<PAGE>   3



         consideration the following factors: The Company's net worth,
         prospective earning power and dividend-paying capacity, and other
         relevant factors. The term "other relevant factors" includes the value
         of any recent private placement; the goodwill of the business; the
         economic outlook in the particular industry; the Company's position in
         the industry and its management; the degree of control of the business
         represented by the block of stock to be valued; and the values of
         securities of corporations engaged in the same or similar lines of
         business which are listed on a stock exchange. In addition to the
         relevant factors described above, consideration shall also be given to
         non-operating assets including proceeds of life insurance policies
         payable to or for the benefit of the Company, to the extent such
         non-operating assets have not been taken into account in the
         determination of net worth, prospective earning power, and
         dividend-earning capacity.

            (b) Except as otherwise set forth in Section 5 above, the term of
         any option shall not be greater than ten (10) years from the date it
         was granted.

            (c) An option by its terms shall not be transferable otherwise than
         by will or the laws of descent and distribution and may be exercisable,
         during the lifetime of the option holder, only by the individual to
         whom the option is granted. Notwithstanding the above, if an employee
         is determined to be incompetent by a court of proper jurisdiction, his
         legal representative may exercise the option on his behalf.

            (d) Options under the Plan may be exercised by a participant
         regardless of whether he is employed by the Company or an Affiliate at
         the time of the exercise.

            (e) Upon termination of a participant's employment (defined as the
         date the participant is no longer employed by either the Company or any
         of its Affiliates), or upon termination of a directorship or of a
         consulting agreement for a non-employee, his rights to exercise an
         option then held by him shall be only as follows:

                (i) If a participant's employment is terminated for any reason
            other than death of the participant, he may, within not less than
            three (3) months following such termination, or within such longer
            period as the Board may fix, exercise the option to the extent such
            option was exercisable by the participant on the date of termination
            of his employment, or to the extent otherwise specified by the
            Board, which may so specify at a time that is subsequent to the date
            of the termination of his employment, provided, the date of exercise
            is in no event after the expiration of the term of the option.
            However, if the participant's employment is terminated due to
            Disability (within the meaning of Section 22(e) of the Code) of the
            participant, then paragraph 6(e) (ii) shall apply to such
            participant by substituting twelve (12) months for three (3) months.

                (ii) If a participant's employment is terminated by death, his
            estate shall have the right for a period of not more than twelve
            (12) months following the date of death, or for such longer period
            as the Board may fix to exercise such option on the date of death,
            or to the extent otherwise specified by the Board, which may so
            specify, at a time that is subsequent to the date of death, provided
            the actual date of exercise is in no event after the expiration of
            the term of the option. A participant's estate shall mean his legal
            representative or any person who acquires the right to exercise an
            option by reason of the participant's death.

            (f) Options may also contain such other provisions, which shall not
         be inconsistent with any of the foregoing terms, as the Board shall
         deem appropriate. No option, however, nor anything contained in the
         Plan, shall confer upon any employee any right to continue in the
         employ of the Company (or Affiliate) nor limit in any way the right of
         the Company (or Affiliate) to terminate his employment at any time.

            (g) In the event of a dissolution or liquidation of the Company, a
         merger in which the Company is not the surviving corporation, a
         transaction in which 100% of the then outstanding voting stock is sold
         or otherwise transferred, or the sale of substantially all of the
         assets of the Company, any or all outstanding options, shall,
         notwithstanding any contrary terms of the grant, accelerate and become
         exercisable in full at least ten days prior to (and shall expire on)
         the consummation of such dissolution, liquidation, merger, sale of
         stock or sale of assets on such conditions as the Board of Directors
         shall determine unless the successor corporation assumes the
         outstanding options or substitutes substantially equivalent options. In
         the event the successor corporation assumes the outstanding options or
         substitutes substantially equivalent options, the options of an
         optionee who is terminated (other than for

                                  CONFIDENTIAL                       PAGE 3 OF 6


<PAGE>   4



         cause) or who resigns for good reason within twelve (12) months after a
         change in control, shall, notwithstanding any contrary terms of the
         grant, accelerate and become exercisable in full. The aggregate fair
         market value (determined at the time an option is granted) of stock
         with respect to ISOs which first become exercisable in the year of such
         dissolution, liquidation, merger, sale of stock or sale of assets
         cannot exceed $100,000. Any remaining accelerated ISOs shall be NSOs.

         7. Payments and Loans Upon Exercise.

            (a) The purchase price of stock sold pursuant to an option shall be
         paid either in full in cash or by check at the time the option is
         exercised or, to the extent permitted under the applicable provisions
         of Delaware General Corporation Law, pursuant to any deferred payment
         arrangement that the Board in its discretion may approve; provided,
         however, that any interest to be paid by an optionee in connection with
         any such deferred payment arrangement shall be charged interest at a
         rate of six percent (6%).

            (b) The Company may make loans or guarantee loans made by an
         appropriate financial institution to individual optionees, including
         officers, on such terms as may be approved by the Board for the purpose
         of financing the exercise of options granted under the Plan and the
         payment of any taxes that may be due by reason of such exercise.

            (c) In addition, to the extent authorized by the Board, optionees
         may make all or any portion of any payment due to the Company upon
         exercise of an option by delivery of any property (including securities
         of the Company) other than cash, so long as such property constitutes
         valid consideration for the stock under applicable law.

            (d) Where the Company has or will have a legal obligation to
         withhold taxes relating to the exercise of any stock option, such
         option may not be exercised, in whole or in part, unless such tax
         obligation is first satisfied in a manner satisfactory to the Company.

         8. Use of Proceeds from Stock. Proceeds from the sale of stock pursuant
to options granted under the Plan shall be used for general corporate purposes.

         9. Stock Transfer Restrictions; Repurchase Provisions. Stock issued
pursuant to the exercise of options granted under the Plan shall be subject to
those stock transfer restrictions and/or repurchase provisions which shall be
set forth in a Restricted Stock Agreement in the form approved by the Board.
Each individual shall be required to execute such agreement prior to receiving
his shares.

         10. Adjustments of the Changes in the Stock. Subject to the provisions
set forth in subsection 6(g) above, in the event the shares of Common Stock of
the Company, as presently constituted shall be changed into a different number
or kind of shares of stock or other securities of the Company or of another
corporation (whether by reason of merger, consolidation, recapitalization,
reclassification, split-up, combination of shares, or otherwise) or if the
number of shares of Common Stock of the Company shall be increased through the
payment of a stock dividend, then there shall be substituted for or added to
each share of Common Stock of the Company, theretofore appropriated or
thereafter subject or which may become subject to an option under the Plan, the
number and kind of shares of stock or other securities into which each
outstanding share of Common Stock of the Company shall be so changed, or to
which each such share shall be entitled, as the case may be. Outstanding options
shall also be amended as to the price and other terms if necessary to reflect
the foregoing events. In the event there shall be any other change in the number
or kind of the outstanding shares of Common Stock of the Company, or of any
stock or other securities into which such Common Stock shall have been changed,
then if the Board of Directors shall, in its sole discretion, determine that
such change equitably requires an adjustment in any option theretofore granted
or which may be granted under the Plan, such adjustment shall be made in
accordance with such determination. No right to purchase fractional shares shall
result from any adjustment in options pursuant to this Section 10. In case of
any such adjustment, the shares subject to the option shall be rounded down to
the nearest whole share. Notice of the any adjustment shall be given by the
Company to each holder of an option which shall have been so adjusted and such
adjustment (whether or not such notice is given) shall be effective and binding
for all purposes of the Plan.

         11. Amendment of the Plan. The Board at any time and from time to time,
may amend the Plan, subject to the limitation, however that except as provided
in Section 10 (relating to adjustments upon changes in stock), no amendment
shall be effective, unless approved, within twelve (12) months before or after
the date of such amendment's adoption, by the vote or written consent of a
majority of the outstanding shares of the Company entitled to vote, where such
amendment will:

            (a) increase the share reserve;

            (b) expand the class of persons who can receive ISOs; or

            (c) comply with any applicable law, regulation, or rule.

            It is expressly contemplated that the Board may amend the Plan in
any respect necessary to provide the Company's employees with the maximum
benefits provided or to be provided under Section 422 of the Code and the
regulations promulgated thereunder relating to employee incentive stock options,
and/or bring the plan or options granted under it into compliance therewith.

            Rights and obligations under any option granted before any amendment
of the Plan shall not be altered or impaired by amendment of the Plan, except
with the consent, which may be obtained in any manner deemed by the Board to be
appropriate of the person to whom the option is granted.

         12. Termination or Suspension of the Plan. The Board at any time may
suspend or terminate the Plan. The Plan, unless sooner terminated, shall
terminate at the end of ten (10) years from the date the Plan is adopted by the
Board or approved by the shareholders of the Company, whichever is earlier. An
option may not be granted under the Plan while the Plan is suspended or after it
is terminated.

             Rights and obligations under any option granted while the Plan is
in effect shall not be altered or impaired by suspension or termination of the
plan, except with the consent of the person to whom the option was granted,
which may be obtained in any manner that the Board deems appropriate.

         13. Time of Granting Options. The date of the grant of an option
hereunder shall, for all purposes, be the date on which the Board (or committee
under authority of the Board) makes the determination granting such option.

         14. Listing, Qualification or Approval of Stock; Approval of Options.
All options granted under the Plan are subject to the requirement that if at any
time the Board shall determine in its discretion that the listing or
qualification of the shares of stock subject thereto on any securities exchange
or under any applicable law, or the consent or approval by any governmental
regulatory body or the shareholders of the Company, is necessary or desirable as
a condition of or in connection with the issuance of shares under the option,
the option may not be exercised in whole or in part, unless such listing,
qualification, consent or approval shall have been effected or obtained free of
any condition not acceptable to the Board.

         15. Binding Effect of Conditions. The conditions and stipulations
hereinabove contained or in any option granted pursuant to the Plan shall be and
constitute a covenant running with all of the shares of the Company owned by the
participant at any time, directly or indirectly whether the same have been
issued or not, and those shares of the Company owned by the participant shall
not be sold, assigned, or transferred by any person save and except in
accordance with the terms and conditions herein provided, and the participant
shall agree to use his best efforts to cause the officers of the Company to
refuse to record on the books of the Company any assignment or transfer made or
attempted to be made, except as provided in the Plan and to cause said officers
to refuse to cancel old certificates or to issue or deliver new certificates
therefor where the purchaser or assignee has acquired certificates of the stock
represented thereby, except strictly in accordance with the provisions of this
plan.

         16. Effective Date of Plan. The Plan shall become effective as
determined by the Board but no options granted under it shall become exercisable
until the Plan has been approved by the vote or written consent of the holders
of a majority of the outstanding shares of the Company entitled to vote. If such
shareholder approval is not obtained within twelve (12) months before or after
the date of the Board's adoption of the Plan, then all options previously
granted under the Plan shall terminate, and no further options shall be granted
and no shares shall be issued. Subject to such limitation, the Board may grant
options under the Plan at any time after the effective date and before the date
fixed herein for termination of the Plan.

         17. Gender. The use of any gender specific pronoun or similar term is
intended to be without legal significance as to gender.

         18. Financial Reports. The Company shall provide financial and other
information regarding the Company pursuant to the provisions set forth in
Section 220 of the General Corporation Law of the State of Delaware.

CHAIRMAN & CEO
CHAPARRAL NETWORK STORAGE, INC.
1951 SOUTH FORDHAM STREET
LONGMONT, CO 80503

This will confirm my understanding with respect to the shares to be issued to me
by reason of my exercise this date of certain stock option rights granted to me
by CHAPARRAL NETWORK STORAGE, INC. for the purchase of _______ shares of Common
Stock (the Shares) as follows:

         (a)      I am acquiring the Shares for my own account for investment
                  with no present intention of dividing my interest with others
                  or of reselling or otherwise disposing of any of the Shares.

         (b)      The Shares are being issued without registration under the
                  Securities Act of 1933 (the "Act") in reliance upon the
                  private offering exemption contained in Section 4(2) of the
                  Act, and such reliance is based in part on the above
                  representation.

         (c)      The certificate for the shares of stock to be issued to me
                  will bear the following legend:

                  "The securities represented by this certificate have been
                  acquired pursuant to an investment representation on the part
                  of the holder hereof. They have not been registered under the
                  Securities Act of 1933 or any state securities laws and may
                  not be sold, pledged, hypothecated, donated or otherwise
                  transferred, unless the Corporation has satisfied itself or
                  has received a favorable option from its counsel, or has
                  received such other evidence as may be satisfactory to its
                  counsel that any contemplated transfer will not be in
                  violation of such laws."

         (d)      Since the Shares have not been registered under the Act, they
                  must be held indefinitely until an exemption from the
                  registration requirements of the Act is available or they are
                  subsequently registered, in which event the representation in
                  Paragraph (a) hereof shall terminate.

         (e)      CHAPARRAL NETWORK STORAGE, INC. is not obligated to comply
                  with the registration requirements of the Act or with the
                  requirements for an exemption under Regulation A under the Act
                  for my benefit.

                           INVESTORS' RIGHTS AGREEMENT

         This Investors' Rights Agreement (this "AGREEMENT") is made and entered
into as of November 25, 1998 by and among Chaparral Technologies, Inc., a
Delaware corporation (the "COMPANY"), the individuals and entities listed on
Exhibit A attached hereto (the "INVESTORS"), and, for purposes of Section 1.3(b)
only, those stockholders of the Company listed on Exhibit B attached hereto (the
"STOCKHOLDERS").

         A. The Investors have agreed to purchase from the Company, and the
Company has agreed to sell to the Investors, shares of the Company's Series A
Preferred Stock ("SERIES A STOCK") on the terms and conditions set forth in that
certain Series A Preferred Stock Purchase Agreement, dated July 10, 1998 by and
between the Company and certain of the Investors (the "PURCHASE AGREEMENT"),
and/or shares of the Company's Series B Preferred Stock ("SERIES B STOCK") on
the terms and conditions set forth in that certain Asset Acquisition Agreement
(the "ACQUISITION AGREEMENT"), dated of even date herewith by and between the
Company and certain of the Investors.

         B. The Purchase Agreement and the Acquisition Agreement provide that
the Investors shall be granted certain information and registration rights and
rights of first refusal, and the Warrant provides that Grayson shall be granted
certain registration rights, all as more fully set forth herein.

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

         1.       INFORMATION RIGHTS.

                  1.1 Financial Information. The Company covenants and agrees
that, commencing on the date of this Agreement, for so long as any Investor
holds shares of Series A Stock issued under the Purchase Agreement and/or shares
of Series B Stock issued under the Acquisition Agreement and/or the equivalent
number (on an as-converted basis) of shares of Common Stock of the Company
("COMPANY STOCK") issued upon the conversion of such shares of Series A Stock or
Series B Stock ("CONVERSION STOCK") the Company will:

                           (a) Annual Reports. Furnish to such Investor, as soon
as practicable and in any event within 120 days after the end of each fiscal
year of the Company, a consolidated Balance Sheet as of the end of such fiscal
year, a consolidated Statement of Income and a consolidated Statement of Cash
Flows of the Company and its subsidiaries for such year, setting forth in each
case in comparative form the figures from the Company's previous fiscal year (if
any), all prepared in accordance with generally accepted accounting principles
and practices and audited by an independent certified public accounting firm;
and

                           (b) Quarterly Reports. Furnish to such Investor as
soon as practicable, and in any case within forty-five (45) days after the end
of each fiscal quarter of the Company (except the last quarter of the Company's
fiscal year), quarterly unaudited financial statements, including an unaudited
Balance Sheet, an unaudited Statement of Income and an unaudited Statement of
Cash Flows, together with a comparison to the Company's operating plan and
budget and statements of



<PAGE>   2



the Chief Financial Officer of the Company explaining any significant
differences in the statements from the Company's operating plan and budget for
the period and stating that such statements fairly present the consolidated
financial position and consolidated financial results of the Company for the
fiscal quarter covered.

Each Investor agrees to hold all information received pursuant to this Section
in confidence, and not to use or disclose any of such information to any third
party, except to the extent such information may be made publicly available by
the Company.

                  1.2 Inspection Rights. The Company shall permit each Investor
holding shares of Series A Stock and/or Series B Stock and/or the equivalent
number (on an as-converted basis) of shares of Conversion Stock, or any
combination thereof, at such Investor's expense, to visit and inspect the
Company's properties, to examine its books of account and records and to discuss
the Company's affairs, finances and accounts with its officers, all at such
reasonable times as may be requested by such Investor. Each Investor agrees to
hold all information received from such inspections in confidence, and not to
use or disclose any of such information to any third party, except to the extent
such information may be made publicly available by the Company.

                  1.3 Board Rights. The Company shall permit Adaptec to have one
(1) representative attend all meetings of the Company's Board of Directors in a
non-voting observer capacity and to receive any communications directed to
members of the Board of Directors in their capacity as such. The Investors agree
to hold all information received from such meetings in confidence, and not to
use or disclose any of such information to any third party, except to the extent
such information may be made publicly available by the Company.

                  1.4 Termination of Certain Rights. The Company's obligations
under Sections 1.1, 1.2 and 1.3 above will terminate upon the closing of the
Company's initial public offering of Common Stock pursuant to an effective
registration statement filed under the U.S. Securities Act of 1933, as amended
(the "SECURITIES ACT"), in which the gross proceeds raised for the Company's
account (calculated before deduction of underwriters' discounts and omissions)
exceeds $15,000,000 at a price greater than $1.10 per share of Common Stock
(such price to be proportionally adjusted to reflect stock splits, stock
dividends and the like).

         2.       REGISTRATION RIGHTS.

                  2.1      Definitions.  For purposes of this Section 2:

                           (a) Registration. The terms "REGISTER,"
"REGISTRATION" and "REGISTERED" refer to a registration effected by preparing,
and filing a registration statement in compliance with the Securities Act, and
the declaration or ordering of effectiveness of such registration statement.

                           (b) Registrable Securities. The term "REGISTRABLE
SECURITIES" means: (i) all the shares of Common Stock of the Company issued or
issuable upon the conversion of any shares of Series A Stock that are now owned
or may hereafter be acquired by the Investors or the Investors' permitted
successors and assigns and (ii) any shares of Common Stock of the Company issued
as (or issuable upon the conversion or exercise of any warrant, right or other
security which

                                       -2-

<PAGE>   3



is issued as) a dividend or other distribution with respect to, or in exchange
for or in replacement of, all such shares of Common Stock described in clause
(i) of this subsection (b); excluding, in all cases, however, any Registrable
Securities sold by a person in a transaction in which rights under this Section
2 are not assigned in accordance with this Agreement or any Registrable
Securities sold to the public or sold pursuant to Rule 144 promulgated under the
Securities Act.

                           (c) Registrable Securities Then Outstanding. The
number of shares of "REGISTRABLE SECURITIES THEN OUTSTANDING" shall mean the
number of shares of Common Stock which are Registrable Securities and (i) are
then issued and outstanding or (ii) are then issuable pursuant to the exercise
or conversion of then outstanding and then exercisable options, warrants or
convertible securities.

                           (d) Holder. For purposes of this Section 2 and
Sections 3 and 4 hereof, the term "HOLDER" means any person owning of record
Registrable Securities that have not been sold to the public or pursuant to Rule
144 promulgated under the Securities Act or any assignee of record of such
Registrable Securities to whom rights under such Sections have been duly
assigned in accordance with this Agreement; provided, however, that for purposes
of this Agreement, a record holder of the Warrant or shares of Series A Stock or
Series B Stock convertible into such Registrable Securities shall be deemed to
be the Holder of such Registrable Securities; and provided, further, that the
Company shall in no event be obligated to register the Warrant or shares of
Series A Stock or Series B Stock, and that Holders of Registrable Securities
will not be required to convert the Warrant or their shares of Series A Stock or
Series B Stock into Common Stock in order to exercise the registration rights
granted hereunder, until immediately before the closing of the offering to which
the registration relates.

                           (e) Form S-3. The term "FORM S-3" means such form
under the Securities Act as is in effect on the date hereof or any successor
registration form under the Securities Act subsequently adopted by the SEC which
permits inclusion or incorporation of substantial information by reference to
other documents filed by the Company with the SEC.

                           (f) SEC. The term "SEC" or "COMMISSION" means the
U.S. Securities and Exchange Commission.

                  2.2      Demand Registration.

                           (a) Request by Holders. If the Company shall receive
at any time after six (6) months after the effective date of the Company's
initial public offering of its securities pursuant to a registration filed under
the Securities Act, a written request from the Holders of at least two-thirds of
the Registrable Securities then outstanding that the Company file a registration
statement under the Securities Act covering the registration of Registrable
Securities pursuant to this Section 2.2, then the Company shall, within twenty
(20) days after the receipt of such written request, give written notice of such
request ("REQUEST NOTICE") to all Holders, and effect, as soon as practicable,
the registration under the Securities Act of all Registrable Securities which
Holders request to be registered and included in such registration by written
notice given by such Holders to the Company within twenty (20) days after
receipt of the Request Notice, subject only to the limitations of this Section
2; provided that the Registrable Securities requested by all Holders to be


                                       -3-

<PAGE>   4



registered pursuant to such request must be at least twenty-five percent (25%)
of all Registrable Securities then outstanding.

                           (b) Underwriting. If the Holders initiating the
registration request under this Section 2.2 ("INITIATING HOLDERS") intend to
distribute the Registrable Securities covered by their request by means of an
underwriting, then they shall so advise the Company as a part of their request
made pursuant to this Section 2.2 and the Company shall include such information
in the written notice referred to in subsection 2.2(a). In such event, the right
of any Holder to include his 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 enter into an
underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting by the Company. Notwithstanding any
other provision of this Section 2.2, if the underwriter(s) advise(s) the Company
in writing that marketing factors require a limitation of the number of
securities to be underwritten then the Company shall so advise all Holders of
Registrable Securities that would otherwise be registered and underwritten
pursuant hereto, and the number of Registrable Securities that may be included
in the underwriting shall be reduced as required by the underwriter(s) and
allocated among the Holders of Registrable Securities on a pro rata basis
according to the number of Registrable Securities then outstanding held by each
Holder requesting registration (including the Initiating Holders); provided,
however, that the number of shares of Registrable Securities to be included in
such underwriting and registration shall not be reduced unless all other
securities of the Company are first entirely excluded from the underwriting and
registration. Any Registrable Securities excluded and withdrawn from such
underwriting shall be withdrawn from the registration.

                           (c) Maximum Number of Demand Registrations. The
Company is obligated to effect only two (2) such registrations pursuant to this
Section 2.2.

                           (d) Deferral. Notwithstanding the foregoing, if the
Company shall furnish to Holders requesting the filing of a registration
statement pursuant to this Section 2.2, a certificate signed by the President or
Chief Executive Officer of the Company stating that in the good faith judgment
of the Board of Directors of the Company, it would be seriously detrimental to
the Company and its stockholders for such registration statement to be filed and
it is therefore essential to defer the filing of such registration statement,
then the Company shall have the right to defer such filing for a period of not
more than 120 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 (12) month period.

                           (e) Expenses. All expenses incurred in connection
with a registration pursuant to this Section 2.2, including without limitation
all registration and qualification fees, printers' and accounting fees, fees and
disbursements of counsel for the Company, and the reasonable fees and
disbursements of one counsel for the selling Holders (but excluding
underwriters' discounts and commissions), shall be borne by the Company. Each
Holder participating in a registration pursuant to this Section 2.2 shall bear
such Holder's proportionate share (based on the total number of shares sold in
such registration other than for the account of the Company) of all discounts,


                                       -4-

<PAGE>   5



commissions or other amounts payable to underwriters or brokers in connection
with such offering. Notwithstanding the foregoing, the Company shall not be
required to pay for any expenses of any registration proceeding begun pursuant
to this Section 2.2 if the registration request is subsequently withdrawn at the
request of the Holders of a majority of the Registrable Securities to be
registered, unless the Holders of a majority of the Registrable Securities then
outstanding are to forfeit their right to one (1) demand registration pursuant
to this Section 2.2 (in which case such right shall be forfeited by all Holders
of Registrable Securities); provided, further, however, that if at the time of
such withdrawal, the Holders have learned of a material adverse change in the
condition, business, or prospects of the Company not known to the Holders at the
time of their request for such registration and have withdrawn their request for
registration with reasonable promptness after learning of such material adverse
change, then the Holders shall not be required to pay any of such expenses and
shall retain their rights pursuant to this Section 2.2.

                  2.3 Piggyback Registrations. The Company shall notify all
Holders of Registrable Securities in writing at least thirty (30) days prior to
filing any registration statement under the Securities Act for purposes of
effecting a public offering of securities of the Company (including, but not
limited to, registration statements relating to secondary offerings of
securities of the Company, but excluding registration statements relating to any
registration under Section 2.2 or Section 2.4 of this Agreement or to any
employee benefit plan or a corporate reorganization) and will afford each such
Holder an opportunity to include in such registration statement all or any part
of the Registrable Securities then held by such Holder. Each Holder desiring to
include in any such registration statement all or any part of the Registrable
Securities held by such Holder shall, within twenty (20) days after receipt of
the above-described notice from the Company, so notify the Company in writing,
and in such notice shall inform the Company of the number of Registrable
Securities such Holder wishes to include in such registration statement. If a
Holder decides not to include all of its Registrable Securities in any
registration statement thereafter filed by the Company, such Holder shall
nevertheless continue to have the right to include any Registrable Securities in
any subsequent registration statement or registration statements as may be filed
by the Company with respect to offerings of its securities, all upon the terms
and conditions set forth herein.

                           (a) Underwriting. If a registration statement under
which the Company gives notice under this Section 2.3 is for an underwritten
offering, then the Company shall so advise the Holders of Registrable
Securities. In such event, the right of any such Holder's Registrable Securities
to be included in a registration pursuant to this Section 2.3 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein. All Holders proposing to distribute their Registrable
Securities through such underwriting shall enter into an underwriting agreement
in customary form with the managing underwriter or underwriter(s) selected for
such underwriting. Notwithstanding any other provision of tills Agreement, if
the managing underwriter determine(s) in good faith that marketing factors
require a limitation of the number of shares to be underwritten, then the
managing underwriter(s) may exclude shares (including Registrable Securities)
from the registration and the underwriting, and the number of shares that may be
included in the registration and the underwriting shall be allocated, first, to
stockholders exercising any demand registration rights, second to the Company,
and third, to each of the Holders requesting inclusion of their Registrable
Securities in such registration statement on a pro rata basis based on the total
number of Registrable Securities then held by each such Holder; provided,
however, that the right of the


                                       -5-

<PAGE>   6



underwriters to exclude shares (including Registrable Securities) from the
registration and underwriting as described above shall be restricted so that:
(i) the number of Registrable Securities included in any such registration is
not reduced below twenty-five percent (25%) of the shares included in the
registration, except for a registration relating to the Company's initial public
offering or an offering solely by stockholders of the Company exercising demand
registration rights, from which all Registrable Securities may be excluded, and
(ii) all shares that are not Registrable Securities and are held by persons who
are employees or directors of the Company (or any subsidiary of the Company)
shall first be excluded from such registration and underwriting before any
Registrable Securities are so excluded. If any Holder disapproves of the terms
of any such underwriting, such Holder may elect to withdraw therefrom by written
notice to the Company and the underwriter, delivered at least twenty (20) days
prior to the effective date of the registration statement. Any Registrable
Securities excluded or withdrawn from such underwriting shall be excluded and
withdrawn from the registration. For any Holder that is a partnership or
corporation, the partners, retired partners and stockholders 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 "Holder," and any pro rata reduction with respect to such "Holder" shall
be based upon the aggregate amount of shares carrying registration rights owned
by all entities and individuals included in such "Holder," as defined in this
sentence.

                           (b) Expenses. All expenses incurred in connection
with a registration pursuant to this Section 2.3 (excluding underwriters' and
brokers' discounts and commissions), including, without limitation all federal
and "blue sky" registration and qualification fees, printers' and accounting,
fees, fees and disbursements of counsel for the Company and reasonable fees and
disbursements of one counsel for the selling Holders shall be borne by the
Company.

                  2.4 Form S-3 Registration. In case the Company shall receive
from any Holder or Holders of at least twenty-five percent (25%) of all
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, then the Company will:

                           (a) Notice. Promptly give written notice of the
proposed registration and the Holder's or Holders' request therefor, and any
related qualification or compliance, to all other Holders of Registrable
Securities; and

                           (b) Registration. As soon as practicable, effect 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 twenty (20) 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 2.4:

                                    (i) if Form S-3 is not available for such
offering;

                                       -6-

<PAGE>   7



                                    (ii) if the Holders, together with the
holders of any other securities of the Company entitled to inclusion in such
registration, propose to sell Registrable Securities and such other securities
(if any) at an aggregate price to the public of less than $1,000,000;

                                    (iii) if the Company shall furnish to the
Holders a certificate signed by the President or Chief Executive Officer of the
Company stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its stockholders
for such Form S-3 Registration to be effected at such time, in which event the
Company shall have the right to defer the filing of the Form S-3 registration
statement no more than once during any twelve month period for a period of not
more than 120 days after receipt of the request of the Holder or Holders under
this Section 2.4;

                                    (iv) if the Company has, within the twelve
(12) month period preceding the date of such request, already effected two (2)
registrations on Form S-3 for the Holders pursuant to this Section 2.4; or

                                    (v) 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) Expenses. Subject to the foregoing, the Company
shall file a, Form S-3 registration statement covering the Registrable
Securities and other securities so requested to be registered pursuant to this
Section 2.4 as soon as practicable after receipt of the request or requests of
the Holders for such registration. The Company shall pay all expenses incurred
in connection with each registration requested pursuant to this Section 2.4,
(excluding underwriters' or brokers' discounts and commissions), including
without limitation all filing, registration and qualification, printers' and
accounting fees and the reasonable fees and disbursements of one counsel for the
selling Holder or Holders and counsel for the Company.

                           (d) Not Demand Registration. Form S-3 registrations
shall not be deemed to be demand registrations as described in Section 2.2
above.

                  2.5 Obligations of the Company. Whenever required to effect
the registration of any Registrable Securities under this Agreement, 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 reasonable,
diligent efforts to cause such registration statement to become effective, and,
upon the request of the Holders of a majority of tile Registrable Securities
registered thereunder, keep such registration statement effective for up to
ninety (90) days.

                           (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 Securities Act with respect to the disposition of all
securities covered by such registration statement.


                                       -7-

<PAGE>   8



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

                           (d) Use reasonable, diligent 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 qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions.

                           (e) In the event of any underwritten public offering,
enter into and perform its obligations under all underwriting agreement, in
usual and customary form, with the managing underwriter(s) 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 Securities 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.

                           (g) Furnish, at the request of any Holder requesting
registration of Registrable Securities, on the date that such Registrable
Securities are delivered to the underwriters for sale, 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 as of 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 and reasonably satisfactory to a majority in interest of the
Holders requesting registration, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities and (ii) a
"comfort" letter dated as of 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 and reasonably satisfactory to a majority in interest of the
Holders requesting registration, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities.

                  2.6 Furnish Information. It shall be a condition precedent to
the obligations of the Company to take any action pursuant to Sections 2.2, 2.3
or 2.4 that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be required to timely effect
the registration of their Registrable Securities.

                  2.7 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 2.

                  2.8 Indemnification. In the event any Registrable Securities
are included in a registration statement under Sections 2.2, 2.3 or 2.4:

                           (a) By the Company. To the extent permitted by law,
the Company will indemnify and hold harmless each Holder, the partners, officers
and directors of each Holder, any underwriter (as defined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Securities Exchange Act of 1934,
as amended, (the "1934 ACT"), against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities 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, "VIOLATIONS" and, individually, 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 Securities Act, the 1934 Act, any federal or state
securities law or any rule or regulation promulgated under the Securities Act,
the 1934 Act or any federal or state securities law in connection with the
offering covered by such registration statement;

and the Company will reimburse each such Holder, partner, officer or director,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability or action; provided however, that the
indemnity agreement contained in this subsection 2.8(a) 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 Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable 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 such Holder, partner, officer, director, underwriter
or controlling person of such Holder.

                           (b) By Selling Holders. To the extent permitted by
law, each selling Holder will indemnify and hold harmless the Company, each of
its directors, each of its officers who have signed the registration statement,
each person, if any, who controls the Company within the meaning of the
Securities Act, any underwriter and any other Holder selling securities under
such registration statement or any of such other Holder's partners, directors or
officers or any person who controls such Holder within the meaning of the
Securities Act or the 1934 Act, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, partner or
director, officer or controlling person of such other Holder may become subject
under the Securities 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


                                       -9-

<PAGE>   10



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 reimburse any legal or other
expenses reasonably incurred by the Company or any such director, officer,
controlling person, underwriter or other Holder, partner, officer, director or
controlling person of such other Holder in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection 2.8(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, that the total
amounts payable in indemnity by a Holder under this Section 2.8(b) in respect of
any Violation shall not exceed the net proceeds received by such Holder in the
registered offering out of which such Violation arises.

                           (c) Notice. Promptly after receipt by an indemnified
party under this Section 2.8 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
2.8, 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; provided, however, that an indemnified
party shall have the right to retain its own 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 conflict of 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 2.8, 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 2.8.

                           (d) Defect Eliminated in Final Prospectus. The
foregoing indemnity agreements of the Company and Holders are subject to the
condition that, insofar as they relate to any Violation made in a preliminary
prospectus but eliminated or remedied in the amended prospectus on file with the
SEC at the time the registration statement in question becomes effective or the
amended prospectus filed with the SEC pursuant to SEC Rule 424(b) (tile "FINAL
PROSPECTUS"), such indemnity agreement shall not inure to the benefit of any
person if a copy of the Final Prospectus was furnished to the indemnified party
and was not furnished to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.

                           (e) Contribution. In order to provide for just and
equitable contribution to joint liability under the Securities Act in any case
in which either (i) any Holder exercising rights under this Agreement, or any
controlling person of any such Holder, makes a claim for indemnification
pursuant to this Section 2.8 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 2.8 provides for indemnification in such case, or


                                      -10-

<PAGE>   11



(ii) contribution under the Securities Act may be required on the part of any
such selling Holder or any such controlling person in circumstances for which
indemnification is provided under this Section 2.8; then, and in each such case,
the Company and such Holder will contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (after contribution from
others) in such proportion so that such Holder is responsible for the portion
represented by the percentage that the public offering price of its Registrable
Securities offered by and sold under the registration statement bears to the
public offering price of all securities offered by and sold under such
registration statement, and the Company and other selling Holders are
responsible for the remaining portion; provided, however, that, in any such
case, (A) no such Holder will be required to contribute any amount in excess of
the public offering price of all such Registrable Securities offered and sold by
such Holder pursuant to such registration statement; and (B) no person or entity
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) will be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation.

                           (f) Survival. The obligations of the Company and
Holders under this Section 2.8 shall survive the completion of any offering of
Registrable Securities in a registration statement, and otherwise.

                  2.9 "Market Stand-Off" Agreement. Each Holder hereby agrees
that it shall not, to the extent requested by the Company or an underwriter of
securities of the Company, sell or otherwise transfer or dispose of any
Registrable Securities or other shares of stock of the Company then owned by
such Holder (other than to donees or partners of the Holder who agree to be
similarly bound) for up to one hundred eighty (180) days following the effective
date of a registration statement of the Company filed under the Securities Act;
provided, however, that:

                           (a) such agreement shall be applicable only to the
first such registration statement of the Company which covers securities to be
sold on its behalf to the public in an underwritten offering but not to
Registrable Securities sold pursuant to such registration statement; and

                           (b) all officers and directors of the Company then
holding Common Stock of the Company enter into similar agreements.

In order to enforce the foregoing covenant, the Company shall have the right to
place restrictive legends on the certificates representing the shares subject to
this Section and to impose stop transfer instructions with respect to the
Registrable Securities and such other shares of stock of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

                  2.10 Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Registrable Securities to the public without
registration, after such time as a public market exists for the Common Stock of
the Company, the Company agrees to:


                                      -11-

<PAGE>   12



                           (a) Make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act, at
all times after the effective date of the first registration under the
Securities Act filed by the Company for an offering of its securities to the
general public;

                           (b) Use reasonable, diligent efforts to file with the
Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the 1934 Act (at any time after it has
become subject to such reporting requirements); and

                           (c) So long as a Holder owns any Registrable
Securities, to furnish to the Holder forthwith upon request a written statement
by the Company as to its compliance with the reporting requirements of said Rule
144 (at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the 1934 Act (at any time
after it has become subject to the reporting requirements of the 1934 Act), a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents of the Company as a Holder may reasonably request in
availing itself of any rule or regulation of the Commission allowing a Holder to
sell any such securities without registration (at any time after the Company has
become subject to the reporting requirements of the 1934 Act).

                  2.11 Termination of the Company's Obligations. The Company
shall have no obligations pursuant to Sections 2.2 through 2.4 with respect to:
(a) any request or requests for registration made by any Holder on a date more
than five (5) years after the closing date of the Company's initial public
offering; or (b) any Registrable Securities proposed to be sold by a Holder in a
registration pursuant to Section 2.2, 2.3 or 2.4 if, in the opinion of counsel
to the Company, all such Registrable Securities proposed to be sold by a Holder
may be sold in a three-month period without registration under the Securities
Act pursuant to Rule 144 under the Securities Act.

                  2.12 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 Registrable Securities then
outstanding, 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
2.2 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 his 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
2.2(a), or within one hundred twenty (120) days of the effective date of any
registration effected pursuant to Section 2.2.

         3.       PRE-EMPTIVE RIGHTS.

                  3.1 General. Each Holder (as defined in Section 2.1(d)) and
any party to whom such Holder's rights under this Section 3 have been duly
assigned in accordance with Section 4.1(b) (each such Holder or assignee being
hereinafter referred to as a "RIGHTS HOLDER") has the right of first refusal to
purchase such Rights Holder's Pro Rata Share (as defined below), of all (or any
part) of


                                      -12-

<PAGE>   13



any "NEW SECURITIES" (as defined in Section 3.2) that the Company may from time
to time issue after the date of this Agreement. A Rights Holder's "PRO RATA
SHARE" for purposes of this right of first refusal is the ratio of (a) the
number of Registrable Securities as to which such Rights Holder is the Holder
(and/or is deemed to be the Holder under Section 2.1(d)), to (b) a number of
shares of Common Stock of the Company equal to the sum of (i) the total number
of shares of Common Stock of the Company then outstanding plus (ii) the total
number of shares of Common Stock of the Company into which all then outstanding
shares of Preferred Stock of the Company are then convertible.

                  3.2 New Securities. "NEW SECURITIES" shall mean any Common
Stock or Preferred Stock of the Company, whether now authorized or not, and
rights, options or warrants to purchase such Common Stock or Preferred Stock,
and securities of any type whatsoever that are, or may become, convertible or
exchangeable into such Common Stock or Preferred Stock; provided, however, that
the term "New Securities" does not include:

                           (a) up to 3,000,000 shares of the Company's Common
Stock (and/or options or warrants therefor) issued to employees, officers,
directors, contractors, advisors or consultants of the Company pursuant to
incentive agreements or plans approved by the Board of Directors of the Company;

                           (b) any shares of Series A Stock or Series B Stock
issued under the Purchase Agreement or the Acquisition Agreement, respectively,
as such agreements may be amended.

                           (c) any securities issuable upon conversion of or
with respect to any then outstanding shares of Series A Stock or Series B Stock
of the Company or Common Stock or other securities issuable upon conversion
thereof,

                           (d) any securities issuable upon exercise of any
options, warrants or rights to purchase any securities of the Company
outstanding on the date of this Agreement "WARRANT SECURITIES") and any
securities issuable upon the conversion of any Warrant Securities or upon the
exercise or conversion of any securities, if such securities were first offered
to the Rights Holders hereunder;

                           (e) shares of the Company's Common Stock or Preferred
Stock issued in connection with any stock split or stock dividend;

                           (f) securities offered by the Company to the public
pursuant to a registration statement filed under the Securities Act;

                           (g) up to 250,000 shares of the Company's Common
Stock or Preferred Stock (and/or options or warrants therefor) issued or
issuable to parties providing the Company with equipment leases, real property
leases, loans, credit lines, guaranties of indebtedness, cash price reductions
or similar financing such number of shares being subject to proportional
adjustment to reflect subdivisions, combinations and stock dividends affecting
the number of outstanding shares of such stock; or


                                      -13-

<PAGE>   14



                           (h) securities issued pursuant to the acquisition of
another corporation or entity by the Company by consolidation, merger, purchase
of all or substantially all of the assets, or other reorganization in which the
Company acquires, in a single transaction or series of related transactions, all
or substantially all of the assets of such other corporation or entity or fifty
percent (50%) or more of the voting power of such other corporation or entity or
fifty percent (50%) or more of the equity ownership of such other entity.

                  3.3 Procedures. In the event that the Company proposes to
undertake an issuance of New Securities, it shall give to each Rights Holder
written notice of its intention to issue New Securities (the "NOTICE"),
describing the type of New Securities and the price and the general terms upon
which the Company proposes to issue such New Securities. Each Rights Holder
shall have ten (10) days from the date of mailing of any such Notice to agree in
writing to purchase such Rights Holder's Pro Rata Share of such New Securities
for the price and upon the general terms specified in the Notice by giving
written notice to the Company and stating therein the quantity of New Securities
to be purchased (not to exceed such Rights Holder's Pro Rata Share). If any
Rights Holder falls to so agree in writing within such ten (10) day period to
purchase such Rights Holder's full Pro Rata Share of an offering, of New
Securities (a "NONPURCHASING HOLDER"), then such Nonpurchasing Holder shall
forfeit the right hereunder to purchase that part of his Pro Rata Share of such
New Securities that he did not so agree to purchase and the Company shall
promptly give each Rights Holder who has timely agreed to purchase his full Pro
Rata Share of such offering of New Securities (a "PURCHASING HOLDER") written
notice of the failure of any Nonpurchasing Holder to purchase such Nonpurchasing
Rights Holder's full Pro Rata Share of such offering of New Securities (the
"OVERALLOTMENT NOTICE"). Each Purchasing Holder shall have a right of
overallotment such that such Purchasing Holder may agree to purchase a portion
of the Nonpurchasing Holders' unpurchased Pro Rata Shares of such offering on a

Rights Holders, at any time within five (5) days after receiving the
Overallotment Notice.

                  3.4 Failure to Exercise. In the event that the Rights Holders

with, and declared effective by, the SEC under the Securities Act, covering the
offer and sale of Common Stock to the public at an offering price of at least
$1.10 per share (such offering price being subject to proportional adjustment to

at any time after six (6) months after the effective date of the Company's
initial public offering of its securities pursuant to a registration filed under
the Securities Act, a written request from the Holders of at least two-thirds of

and such Holder) to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall enter into an
underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting by the Company. Notwithstanding any
other provision of this Section 2.2, if the underwriter(s) advise(s) the Company
in writing that marketing factors require a limitation of the number of
securities to be underwritten then the Company shall so advise all Holders of
Registrable Securities that would otherwise be registered and underwritten
pursuant hereto, and the number of Registrable Securities that may be included
in the underwriting shall be reduced as required by the underwriter(s) and
allocated among the Holders of Registrable Securities on a pro rata basis
according to the number of Registrable Securities then outstanding held by each
Holder requesting registration (including the Initiating Holders); provided,
however, that the number of shares of Registrable Securities to be included in
such underwriting and registration shall not be reduced unless all other
securities of the Company are first entirely excluded from the underwriting and
registration. Any Registrable Securities excluded and withdrawn from such
underwriting shall be withdrawn from the registration.

                           (c) Maximum Number of Demand Registrations. The
Company is obligated to effect only two (2) such registrations pursuant to this
Section 2.2.

                           (d) Deferral. Notwithstanding the foregoing, if the
Company shall furnish to Holders requesting the filing of a registration
statement pursuant to this Section 2.2, a



                                      -4-
<PAGE>   5

certificate signed by the President or Chief Executive Officer of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its stockholders
for such registration statement to be filed and it is therefore essential to
defer the filing of such registration statement, then the Company shall have the
right to defer such filing for a period of not more than 120 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 (12) month period.

                           (e) Expenses. All expenses incurred in connection
with a registration pursuant to this Section 2.2, including without limitation
all registration and qualification fees, printers' and accounting fees, fees and
disbursements of counsel for the Company, and the reasonable fees and
disbursements of one counsel for the selling Holders (but excluding
underwriters' discounts and commissions), shall be borne by the Company. Each
Holder participating in a registration pursuant to this Section 2.2 shall bear
such Holder's proportionate share (based on the total number of shares sold in
such registration other than for the account of the Company) of all discounts,
commissions or other amounts payable to underwriters or brokers in connection
with such offering. Notwithstanding the foregoing, the Company shall not be
required to pay for any expenses of any registration proceeding begun pursuant
to this Section 2.2 if the registration request is subsequently withdrawn at the
request of the Holders of a majority of the Registrable Securities to be
registered, unless the Holders of a majority of the Registrable Securities then
outstanding agree to forfeit their right to one (1) demand registration pursuant
to this Section 2.2 (in which case such right shall be forfeited by all Holders
of Registrable Securities); provided, further, however, that if at the time of
such withdrawal, the Holders have learned of a material adverse change in the
condition, business, or prospects of the Company not known to the Holders at the
time of their request for such registration and have withdrawn their request for
registration with reasonable promptness after learning of such material adverse
change, then the Holders shall not be required to pay any of such expenses and
shall retain their rights pursuant to this Section 2.2.

                  2.3 Piggyback Registrations. The Company shall notify all
Holders of Registrable Securities in writing at least thirty (30) days prior to
filing any registration statement under the Securities Act for purposes of
effecting a public offering of securities of the Company (including, but not
limited to, registration statements relating to secondary offerings of
securities of the Company, but excluding registration statements relating to any
registration under Section 2.2 or Section 2.4 of this Agreement or to any
employee benefit plan or a corporate reorganization) and will afford each such
Holder an opportunity to include in such registration statement all or any part
of the Registrable Securities then held by such Holder. Each Holder desiring to
include in any such registration statement all or any part of the Registrable
Securities held by such Holder shall, within twenty (20) days after receipt of
the above-described notice from the Company, so notify the Company in writing,
and in such notice shall inform the Company of the number of Registrable
Securities such Holder wishes to include in such registration statement. If a
Holder decides not to include all of its Registrable Securities in any
registration statement thereafter filed by the Company, such Holder shall
nevertheless continue to have the right to include any Registrable Securities in
any subsequent registration statement or



                                      -5-
<PAGE>   6

registration statements as may be filed by the Company with respect to offerings
of its securities, all upon the terms and conditions set forth herein.

                           (a) Underwriting. If a registration statement under
which the Company gives notice under this Section 2.3 is for an underwritten
offering, then the Company shall so advise the Holders of Registrable
Securities. In such event, the right of any such Holder's Registrable Securities
to be included in a registration pursuant to this Section 2.3 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein. All Holders proposing to distribute their Registrable
Securities through such underwriting shall enter into an underwriting agreement
in customary form with the managing underwriter or underwriter(s) selected for
such underwriting. Notwithstanding any other provision of this Agreement, if the
managing underwriter determine(s) in good faith that marketing factors require a
limitation of the number of shares to be underwritten, then the managing
underwriter(s) may exclude shares (including Registrable Securities) from the
registration and the underwriting, and the number of shares that may be included
in the registration and the underwriting shall be allocated, first, to
stockholders exercising any demand registration rights, second to the Company,
and third, to each of the Holders requesting inclusion of their Registrable
Securities in such registration statement on a pro rata basis based on the total
number of Registrable Securities then held by each such Holder; provided
however, that the right of the underwriters to exclude shares (including
Registrable Securities) from the registration and underwriting as described
above shall be restricted so that: (i) the number of Registrable Securities
included in any such registration is not reduced below twenty-five percent (25%)
of the shares included in the registration, except for a registration relating
to the Company's initial public offering or an offering solely by stockholders
of the Company exercising demand registration rights, from which all Registrable
Securities may be excluded, and (ii) all shares that are not Registrable
Securities and are held by persons who are employees or directors of the Company
(or any subsidiary of the Company) shall first be excluded from such
registration and underwriting before any Registrable Securities are so excluded.
If any Holder disapproves of the terms of any such underwriting, such Holder may
elect to withdraw therefrom by written notice to the Company and the
underwriter, delivered at least twenty (20) days prior to the effective date of
the registration statement. Any Registrable Securities excluded or withdrawn
from such underwriting shall be excluded and withdrawn from the registration.
For any Holder that is a partnership or corporation, the partners, retired
partners and stockholders 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 "Holder," and any pro rata
reduction with respect to such "Holder" shall be based upon the aggregate amount
of shares carrying registration rights owned by all entities and individuals
included in such "Holder," as defined in this sentence.

                           (b) Expenses. All expenses incurred in connection
with a registration pursuant to this Section 2.3 (excluding underwriters' and
brokers' discounts and commissions), including, without limitation all federal
and "blue sky" registration and qualification fees, printers' and accounting
fees, fees and disbursements of counsel for the Company and reasonable fees and
disbursements of one counsel for the selling Holders shall be borne by the
Company.

                  2.4 Form S-3 Registration. In case the Company shall receive
from any Holder or Holders of at least twenty-five percent (25%) of all
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, then the Company will:

                           (a) Notice. Promptly give written notice of the
proposed registration and the Holder's or Holders' request therefor, and any
related qualification or compliance, to all other Holders of Registrable
Securities; and

                           (b) Registration. As soon as practicable, effect 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 twenty (20) 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 2.4:

                                     (i) if Form S-3 is not available for such
offering;

                                     (ii) if the Holders, together with the
holders of any other securities of the Company entitled to inclusion in such
registration, propose to sell Registrable Securities and such other securities
(if any) at an aggregate price to the public of less than $1,000,000;

                                     (iii) if the Company shall furnish to the
Holders a certificate signed by the President or Chief Executive Officer of the
Company stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its stockholders
for such Form S-3 Registration to be effected at such time, in which event the
Company shall have the right to defer the filing of the Form S-3 registration
statement no more than once during any twelve month period for a period of not
more than 120 days after receipt of the request of the Holder or Holders under
this Section 2.4;

                                     (iv) if the Company has, within the twelve
(12) month period preceding the date of such request, already effected two (2)
registrations on Form S-3 for the Holders pursuant to this Section 2.4; or

                                     (v) 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) Expenses. Subject to the foregoing, the Company
shall file a Form S-3 registration statement covering the Registrable Securities
and other securities so requested to be registered pursuant to this Section 2.4
as soon as practicable after receipt of the request or requests of the Holders
for such registration. The Company shall pay all expenses



                                      -7-
<PAGE>   8

incurred in connection with each registration requested pursuant to this Section
2.4, (excluding underwriters' or brokers' discounts and commissions), including
without limitation all filing, registration and qualification, printers' and
accounting fees and the reasonable fees and disbursements of one counsel for the
selling Holder or Holders and counsel for the Company.

                           (d) Not Demand Registration. Form S-3 registrations
shall not be deemed to be demand registrations as described in Section 2.2
above.

                  2.5 Obligations of the Company. Whenever required to effect
the registration of any Registrable Securities under this Agreement, 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 reasonable,
diligent 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, keep such registration statement effective for up to
ninety (90) days.

                           (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 Securities Act with respect to the disposition of all
securities covered by such registration statement.

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

                           (d) Use reasonable, diligent 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 qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions.

                           (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(s) 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 Securities 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.



                                      -8-
<PAGE>   9

                           (g) Furnish, at the request of any Holder requesting
registration of Registrable Securities, on the date that such Registrable
Securities are delivered to the underwriters for sale, 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 as of 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 and reasonably satisfactory to a majority in interest of the
Holders requesting registration, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities and (ii) a
"comfort" letter dated as of 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 and reasonably satisfactory to a majority in interest of the
Holders requesting registration, addressed to the underwriters, if any, and to
the Holders requesting registration of Registrable Securities.

                  2.6 Furnish Information. It shall be a condition precedent to
the obligations of the Company to take any action pursuant to Sections 2.2, 2.3
or 2.4 that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be required to timely effect
the registration of their Registrable Securities.

                  2.7 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 2.

                  2.8 Indemnification. In the event any Registrable Securities
are included in a registration statement under Sections 2.2, 2.3 or 2.4:

                           (a) By the Company. To the extent permitted by law,
the Company will indemnify and hold harmless each Holder, the partners, officers
and directors of each Holder, any underwriter (as defined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Securities Exchange Act of 1934,
as amended, (the "1934 ACT"), against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities Act, the l934 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, "VIOLATIONS" and, individually, 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



                                      -9-
<PAGE>   10

                                    (iii) any violation or alleged violation by
the Company of the Securities Act, the 1934 Act, any federal or state securities
law or any rule or regulation promulgated under the Securities Act, the 1934 Act
or any federal or state securities law in connection with the offering covered
by such registration statement; and the Company will reimburse each such Holder,
partner, officer or director, underwriter or controlling person for any legal or
other expenses reasonably incurred by them, as incurred, in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided however, that the indemnity agreement contained in this subsection
2.8(a) 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 Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable 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 such Holder, partner,
officer, director, underwriter or controlling person of such Holder.

                           (b) By Selling Holders. To the extent permitted by
law, each selling Holder will indemnify and hold harmless the Company, each of
its directors, each of its officers who have signed the registration statement,
each person, if any, who controls the Company within the meaning of the
Securities Act, any underwriter and any other Holder selling securities under
such registration statement or any of such other Holder's partners, directors or
officers or any person who controls such Holder within the meaning of the
Securities Act or the 1934 Act, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, partner or
director, officer or controlling person of such other Holder may become subject
under the Securities 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 reimburse any
legal or other expenses reasonably incurred by the Company or any such director,
officer, controlling person, underwriter or other Holder, partner, officer,
director or controlling person of such other Holder in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the indemnity agreement contained in this subsection
2.8(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, that the total amounts payable in indemnity by a Holder under this
Section 2.8(b) in respect of any Violation shall not exceed the net proceeds
received by such Holder in the registered offering out of which such Violation
arises.

                           (c) Notice. Promptly after receipt by an indemnified
party under this Section 2.8 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
2.8, 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



                                      -10-
<PAGE>   11

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; provided, however, that an indemnified
party shall have the right to retain its own 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 conflict of 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 2.8, 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 2.8.

                           (d) Defect Eliminated in Final Prospectus. The
foregoing indemnity agreements of the Company and Holders are subject to the
condition that, insofar as they relate to any Violation made in a preliminary
prospectus but eliminated or remedied in the amended prospectus on file with the
SEC at the time the registration statement in question becomes effective or the
amended prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "FINAL
PROSPECTUS"), such indemnity agreement shall not inure to the benefit of any
person if a copy of the Final Prospectus was furnished to the indemnified party
and was not furnished to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.

                           (e) Contribution. In order to provide for just and
equitable contribution to joint liability under the Securities Act in any case
in which either (i) any Holder exercising rights under this Agreement, or any
controlling person of any such Holder, makes a claim for indemnification
pursuant to this Section 2.8 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 2.8 provides for indemnification in such case, or (ii) contribution
under the Securities Act may be required on the part of any such selling Holder
or any such controlling person in circumstances for which indemnification is
provided under this Section 2.8; then, and in each such case, the Company and
such Holder will contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (after contribution from others) in
such proportion so that such Holder is responsible for the portion represented
by the percentage that the public offering price of its Registrable Securities
offered by and sold under the registration statement bears to the public
offering price of all securities offered by and sold under such registration
statement, and the Company and other selling Holders are responsible for the
remaining portion; provided, however, that, in any such case, (A) no such Holder
will be required to contribute any amount in excess of the public offering price
of all such Registrable Securities offered and sold by such Holder pursuant to
such registration statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
will be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.



                                      -11-
<PAGE>   12

                           (f) Survival. The obligations of the Company and
Holders under this Section 2.8 shall survive the completion of any offering of
Registrable Securities in a registration statement, and otherwise.

                  2.9 "Market Stand-Off" Agreement. Each Holder hereby agrees
that it shall not, to the extent requested by the Company or an underwriter of
securities of the Company, sell or otherwise transfer or dispose of any
Registrable Securities or other shares of stock of the Company then owned by
such Holder (other than to donees or partners of the Holder who agree to be
similarly bound) for up to one hundred eighty (180) days following the effective
date of a registration statement of the Company filed under the Securities Act;
provided, however, that:

                           (a) such agreement shall be applicable only to the
first such registration statement of the Company which covers securities to be
sold on its behalf to the public in an underwritten offering but not to
Registrable Securities sold pursuant to such registration statement; and

                           (b) all officers and directors of the Company then
holding Common Stock of the Company enter into similar agreements.

In order to enforce the foregoing covenant, the Company shall have the right to
place restrictive legends on the certificates representing the shares subject to
this Section and to impose stop transfer instructions with respect to the
Registrable Securities and such other shares of stock of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

                  2.10 Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Registrable Securities to the public without
registration, after such time as a public market exists for the Common Stock of
the Company, the Company agrees to:

                           (a) Make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act, at
all times after the effective date of the first registration under the
Securities Act filed by the Company for an offering of its securities to the
general public;

                           (b) Use reasonable, diligent efforts to file with the
Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the 1934 Act (at any time after it has
become subject to such reporting requirements); and

                           (c) So long as a Holder owns any Registrable
Securities, to furnish to the Holder forthwith upon request a written statement
by the Company as to its compliance with the reporting requirements of said Rule
144 (at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the 1934 Act (at any time
after it has become subject to the reporting requirements of the 1934 Act), a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents of the Company as a



                                      -12-
<PAGE>   13

Holder may reasonably request in availing itself of any rule or regulation of
the Commission allowing a Holder to sell any such securities without
registration (at any time after the Company has become subject to the reporting
requirements of the 1934 Act).

                  2.11 Termination of the Company's Obligations. The Company
shall have no obligations pursuant to Sections 2.2 through 2.4 with respect to
any request or requests for registration made by any Holder on a date more than
five (5) years after the closing date of the Company's initial public offering.
Notwithstanding anything to the contrary contained in Section 2.2 or 2.4, if any
Holder is eligible to sell Registrable Securities pursuant Rule 144(k) or any
successor provision under the Securities Act (an "Excluded Holder"), the
Registrable Securities of such Excluded Holder shall be disregarded in
determining the requisite percentage of Registrable Securities that are required
to initiate a registration pursuant to Section 2.2 or 2.4 (i.e., a registration
under Section 2.2 must be initiated by persons holding at least two-thirds of
the Registrable Securities held by all Holders who are not Excluded Holders and
a registration under Section 2.4 must be initiated by persons holding at least
25% of the Registrable Securities held by all Holders who are not Excluded
Holders). After a registration has been requested pursuant to Section 2.2 or
2.4, as the case may be, by the requisite percentage of shares held by Holders
who are not Excluded Holders, all Holders (including Excluded Holders) shall be
entitled to include their Registrable Securities in such registration subject to
the terms and conditions of this Agreement.

                  2.12 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 Registrable Securities then
outstanding, 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
2.2 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 his 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
2.2(a), or within one hundred twenty (120) days of the effective date of any
registration effected pursuant to Section 2.2.

         3. PRE-EMPTIVE RIGHTS.

                  3.1 General. Each Holder (as defined in Section 2.1(d)) and
any party to whom such Holder's rights under this Section 3 have been duly
assigned in accordance with Section 4.1(b) (each such Holder or assignee being
hereinafter referred to as a "RIGHTS HOLDER") has the right of first refusal to
purchase such Rights Holder's Pro Rata Share (as defined below), of all (or any
part) of any "New Securities" (as defined in Section 3.2) that the Company may
from time to time issue after the date of this Agreement. A Rights Holder's "PRO
RATA SHARE" for purposes of this right of first refusal is the ratio of (a) the
number of Registrable Securities as to which such Rights Holder is the Holder
(and/or is deemed to be the Holder under Section 2.1(d)), to (b) a number of
shares of Common Stock of the Company equal to the sum of (i) the total number
of shares of Common Stock of the Company then outstanding plus (ii) the total
number of



                                      -13-
<PAGE>   14

shares of Common Stock of the Company into which all then outstanding shares of
Preferred Stock of the Company are then convertible.

                  3.2 New Securities. "NEW SECURITIES" shall mean any Common
Stock or Preferred Stock of the Company, whether now authorized or not, and
rights, options or warrants to purchase such Common Stock or Preferred Stock,
and securities of any type whatsoever that are, or may become, convertible or
exchangeable into such Common Stock or Preferred Stock; provided, however, that
the term "New Securities" does not include:

                           (a) up to 3,500,000 shares of the Company's Common
Stock (and/or options or warrants therefor) issued to employees, officers,
directors, contractors, advisors or consultants of the Company pursuant to
incentive agreements or plans approved by the Board of Directors of the Company;

                           (b) any shares of Series A Stock issued under the
Purchase Agreement, as such agreement may be amended.

                           (c) any securities issuable upon conversion of or
with respect to any then outstanding shares of Series A Stock or Series B Stock
of the Company or Common Stock or other securities issuable upon conversion
thereof;

                           (d) any securities issuable upon exercise of any
options, warrants or rights to purchase any securities of the Company
outstanding on the date of this Agreement ("WARRANT SECURITIES") and any
securities issuable upon the conversion of any Warrant Securities or upon the
exercise or conversion of any securities, if such securities were first offered
to the Rights Holders hereunder;

                           (e) shares of the Company's Common Stock or Preferred
Stock issued in connection with any stock split or stock dividend;

                           (f) securities offered by the Company to the public
pursuant to a registration statement filed under the Securities Act;

                           (g) up to 250,000 shares of the Company's Common
Stock or Preferred Stock (and/or options or warrants therefor) issued or
issuable to parties providing the Company with equipment leases, real property
leases, loans, credit lines, guaranties of indebtedness, cash price reductions
or similar financing such number of shares being subject to proportional
adjustment to reflect subdivisions, combinations and stock dividends affecting
the number of outstanding shares of such stock; or

                           (h) securities issued pursuant to the acquisition of
another corporation or entity by the Company by consolidation, merger, purchase
of all or substantially all of the assets, or other reorganization in which the
Company acquires, in a single transaction or series of related transactions, all
or substantially all of the assets of such other corporation or entity or fifty
percent (50%) or more of the voting power of such other corporation or entity or
fifty percent (50%) or more of the equity ownership of such other entity.

<PAGE>   15

                  3.3 Procedures. In the event that the Company proposes to
undertake an issuance of New Securities, it shall give to each Rights Holder
written notice of its intention to issue New Securities (the "NOTICE"),
describing the type of New Securities and the price and the general terms upon
which the Company proposes to issue such New Securities. Each Rights Holder
shall have ten (10) days from the date of mailing of any such Notice to agree in
writing to purchase such Rights Holder's Pro Rata Share of such New Securities
for the price and upon the general terms specified in the Notice by giving
written notice to the Company and stating therein the quantity of New Securities
to be purchased (not to exceed such Rights Holder's Pro Rata Share). If any
Rights Holder fails to so agree in writing within such ten (10) day period to
purchase such Rights Holder's full Pro Rata Share of an offering of New
Securities (a "NONPURCHASING HOLDER"), then such Nonpurchasing Holder shall
forfeit the right hereunder to purchase that part of his Pro Rata Share of such
New Securities that he did not so agree to purchase and the Company shall
promptly give each Rights Holder who has timely agreed to purchase his full Pro
Rata Share of such offering of New Securities (a "PURCHASING HOLDER") written
notice of the failure of any Nonpurchasing Holder to purchase such Nonpurchasing
Rights Holder's full Pro Rata Share of such offering of New Securities (the
"OVERALLOTMENT NOTICE"). Each Purchasing Holder shall have a right of
overallotment such that such Purchasing Holder may agree to purchase a portion
of the Nonpurchasing Holders' unpurchased Pro Rata Shares of such offering on a
pro rata basis according to the relative Pro Rata Shares of the Purchasing
Rights Holders, at any time within five (5) days after receiving the
Overallotment Notice.

                  3.4 Failure to Exercise. In the event that the Rights Holders
fail to exercise in full the right of first refusal within such ten (10) plus
five (5) day period, then the Company shall have 120 days thereafter to sell the
New Securities with respect to which the Rights Holders' rights of first refusal
hereunder were not exercised, at a price and upon general terms not materially
more favorable to the purchasers thereof than specified in the Company's Notice
to the Rights Holders. In the event that the Company has not issued and sold the
New Securities within such 120-day period, then the Company shall not thereafter
issue or sell any New Securities without again first offering such New
Securities to the Rights Holders pursuant to this Section 3.

                  3.5 Termination. This right of first refusal shall terminate
(a) immediately before the closing of the first underwritten sale of Common
Stock of the Company to the public pursuant to a registration statement filed
with, and declared effective by, the SEC under the Securities Act, covering the
offer and sale of Common Stock to the public at an offering price of at least
$1.10 per share (such offering price being subject to proportional adjustment to
reflect subdivisions, combinations, stock dividends and similar transactions
affecting the number of outstanding shares of Common Stock) for an aggregate
gross public offering price (calculated before deduction of underwriters'
discounts and commissions) of at least $15,000,000 or (b) upon (i) the
acquisition of all or substantially all the assets of the Company or (ii) an
acquisition of the Company by another corporation or entity by consolidation,
merger or other reorganization in which the holders of the Company's outstanding
voting stock immediately prior to such transaction own, immediately after such
transaction, securities representing less than fifty percent (50%) or more of
the voting power of the corporation or other entity surviving such transaction.

         4. ASSIGNMENT AND AMENDMENT.

                  4.1 Assignment. Notwithstanding anything herein to the
contrary:

                           (a) Information Rights. The rights of an Investor
under Section 1.1 or 1.2 or 1.4 hereof may be assigned only to a party who
acquires from an Investor (or an Investor's permitted assigns) at least 500,000
shares of Series A Stock and/or Series B Stock subject to this Agreement and/or
an equivalent number (on an as-converted basis) of Registrable Securities issued
upon conversion thereof.

                           (b) Registration Rights; Refusal Rights. The
registration rights of a Holder under Section 2 hereof and the rights of first
refusal of a Rights Holder under Section 3 hereof may be assigned only to a
party who acquires at least 500,000 shares of Series A Stock and/or Series B
Stock subject to this Agreement and/or an equivalent number (on an as-converted
basis) of Registrable Securities issued upon conversion thereof; provided,
however that no party may be assigned any of the foregoing rights unless the
Company is given written notice by the assigning party at the time of such
assignment stating the name and address of the assignee and identifying the
securities of the Company as to which the rights in question are being assigned;
and provided further that any such assignee shall receive such assigned rights
subject to all the terms and conditions of this Agreement, including without
limitation the provisions of this Section 4.

                  4.2 Amendment of Rights. Any provision of this Agreement may

particular instance and either retroactively or prospectively), only with the
written consent of the Company and Investors (and/or any of their permitted
successors or assigns) holding shares of Series A Stock, Series B Stock and/or
Conversion Stock representing and/or convertible into a majority of all the
Investors' Shares (as defined below). As used herein, the term "INVESTORS'
SHARES" shall mean the shares of Common Stock then issuable upon conversion of
all then outstanding shares of Series A Stock issued and Series B Stock subject
to this Agreement plus all then outstanding shares of Conversion Stock that were
issued upon the conversion of any shares of Series A Stock and shares of Series
B Stock subject to this Agreement. Any amendment or waiver effected in
accordance with this Section 4.2 shall be binding upon each Investor, each
Holder, each permitted successor or assignee of such Investor or Holder and the
Company.

         5. GENERAL PROVISIONS.

                  5.1 Notices. Any notice, request or other communication

to conflict of laws and choice of law.

                  5.4 Severability. If one or more provisions of this Agreement

                   SECOND AMENDED INVESTORS' RIGHTS AGREEMENT

         This Second Amended Investors' Rights Agreement (this "AGREEMENT") is
made and entered into as of August 13, 1999 by and among Chaparral Network
Storage, Inc. (formerly Chaparral Technologies Inc.), a Delaware corporation
(the "COMPANY"), the individuals and entities listed on Exhibit A attached
hereto (the "CURRENT INVESTORS"), and the entities listed on Exhibit B attached
hereto (the "NEW INVESTORS" and together with the Current Investors, the
"INVESTORS").

         A. The Current Investors are party to that certain First Amended
Investors' Rights Agreement dated as of March 31, 1999 (the "FIRST AMENDED
AGREEMENT").

         B. The New Investors have agreed to purchase from the Company, and the
Company has agreed to sell to the New Investors, shares of the Company's Series
C Preferred Stock on the terms and conditions set forth in that certain Series C
Preferred Stock Purchase Agreement, dated August 13, 1999 by and between the
Company and each New Investor (the "PURCHASE AGREEMENT").

         C. It is a condition to the New Investors' obligations to enter into
the Purchase Agreement that this Agreement be executed by the parties hereto.

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

         1. INFORMATION RIGHTS.

                  1.1 Financial Information. The Company covenants and agrees
that, commencing on the date of this Agreement, for so long as any Investor
holds shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock and/or shares of Common Stock of the Company ("COMMON STOCK")
issued upon the conversion of such shares of Series A Preferred Stock or Series
B Preferred Stock or Series C Preferred Stock ("CONVERSION STOCK") the Company
will:

                           (a)      Annual Reports. Furnish to such Investor,
as soon as practicable and in any event within 120 days after the end of each
fiscal year of the Company, a consolidated Balance Sheet as of the end of such
fiscal year, a consolidated Statement of Income and a consolidated Statement of
Cash Flows of the Company and its subsidiaries for such year, setting forth in
each case in comparative form the figures from the Company's previous fiscal
year (if any), all prepared in accordance with generally accepted accounting
principles and practices and audited by an independent certified public
accounting firm; and

                           (b)      Quarterly Reports. Furnish to such Investor
as soon as practicable, and in any case within forty-five (45) days after the
end of each fiscal quarter of the Company (except the last quarter of the
Company's fiscal year), quarterly unaudited financial statements,


                                       1
<PAGE>   2


including an unaudited Balance Sheet, an unaudited Statement of Income and an
unaudited Statement of Cash Flows, together with a comparison to the Company's
operating plan and budget and statements of the Chief Financial Officer of the
Company explaining any significant differences in the statements from the
Company's operating plan and budget for the period and stating that such
statements fairly present the consolidated financial position and consolidated
financial results of the Company for the fiscal quarter covered.

Each Investor agrees to hold all information received pursuant to this Section
in confidence, and not to use or disclose any of such information to any third
party, except to the extent such information may be made publicly available by
the Company.

                  1.2 Inspection Rights. The Company shall permit each Investor
holding shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock and/or shares of Conversion Stock, or any combination thereof,
at such Investor's expense, to visit and inspect the Company's properties, to
examine its books of account and records and to discuss the Company's affairs,
finances and accounts with its officers, all at such reasonable times as may be
requested by such Investor. Each Investor agrees to hold all information
received from such inspections in confidence, and not to use or disclose any of
such information to any third party, except to the extent such information may
be made publicly available by the Company.

                  1.3 Board Rights. The Company shall permit Adaptec to have one
(1) representative attend all meetings of the Company's Board of Directors in a
non-voting observer capacity and to receive any communications directed to
members of the Board of Directors in their capacity as such. The Investors agree
to hold all information received from such meetings in confidence, and not to
use or disclose any of such information to any third party, except to the extent
such information may be made publicly available by the Company.

                  1.4 Termination of Certain Rights. The Company's obligations
under Sections 1.1, 1.2 and 1.3 above will terminate upon the closing of the
Company's initial public offering of Common Stock pursuant to an effective
registration statement filed under the U.S. Securities Act of 1933, as amended
(the "SECURITIES ACT"), in which the gross proceeds raised for the Company's
account (calculated before deduction of underwriters' discounts and omissions)
exceeds $15,000,000 at a price greater than $1.10 per share of Common Stock
(such price to be proportionally adjusted to reflect stock splits, stock
dividends and the like).

                  2.  REGISTRATION RIGHTS.

                  2.1 Definitions. For purposes of this Section 2:

                           (a) Registration. The terms "REGISTER,"
"REGISTRATION" and "REGISTERED" and refer to a registration effected by
preparing and filing a registration statement in compliance with the Securities
Act, and the declaration or ordering of effectiveness of such registration
statement.

                           (b) Registrable Securities. The term "REGISTRABLE
SECURITIES" means: (i) all the shares of Common Stock of the Company issued or
issuable upon the conversion of any


                                       2
<PAGE>   3


shares of Series A Preferred Stock, Series B Preferred Stock or Series C
Preferred Stock that are now owned or may hereafter be acquired by the Investors
or the Investors' permitted successors and assigns and (ii) any shares of Common
Stock of the Company issued as (or issuable upon the conversion or exercise of
any warrant, right or other security which is issued as) a dividend or other
distribution with respect to, or in exchange for or in replacement of, all such
shares of Common Stock described in clause (i) of this subsection (b); excluding
in all cases, however, any Registrable Securities sold by a person in a
transaction in which rights under this Section 2 are not assigned in accordance
with this Agreement or any Registrable Securities sold to the public or sold
pursuant to Rule 144 promulgated under the Securities Act.

                           (c) Registrable Securities Then Outstanding. The
number of shares of "REGISTRABLE SECURITIES THEN OUTSTANDING" shall mean the
number of shares of Common Stock which are Registrable Securities and (i) are
then issued and outstanding or (ii) are then issuable pursuant to the exercise
or conversion of then outstanding and then exercisable options, warrants or
convertible securities.

                           (d) Holder. For purposes of this Section 2 and
Sections 3 and 4 hereof, the term "HOLDER" means any person owning of record
Registrable Securities that have not been sold to the public or pursuant to Rule
144 promulgated under the Securities Act or any assignee of record of such
Registrable Securities to whom rights under such Sections have been duly
assigned in accordance with this Agreement; provided, however, that for purposes
of this Agreement, a record holder of the Warrant or shares of Series A Stock,
Series B Stock or Series C Stock convertible into such Registrable Securities
shall be deemed to be the Holder of such Registrable Securities; and provided,
further, that the Company shall in no event be obligated to register the Warrant
or shares of Series A Stock, Series B Stock, or Series C Stock and that Holders
of Registrable Securities will not be required to convert the Warrant or their
shares of Series A Stock, Series B Stock or Series C Stock into Common Stock in
order to exercise the registration rights granted hereunder, until immediately
before the closing of the offering to which the registration relates.

                           (e) Form S-3. The term "FORM S-3" means such form
under the Securities Act as is in effect on the date hereof or any successor
registration form under the Securities Act subsequently adopted by the SEC which
permits inclusion or incorporation of substantial information by reference to
other documents filed by the Company with the SEC.

                           (f) SEC. The term "SEC" or "COMMISSION" means the
U.S. Securities and Exchange Commission.

                           (g) Series A Stock. The term "SERIES A STOCK" shall
mean the Company's Series A Preferred Stock, par value $0.001 per share.

mean the Company's Series B Preferred Stock, par value $0.001 per share.

                           (i) Series C Stock. The term "SERIES C STOCK" shall

                  2.2 Demand Registration.

                           (a) Request by Holders. If the Company shall receive
at any time after six (6) months after the effective date of the Company's
initial public offering of its securities pursuant to a registration filed under
the Securities Act, a written request from the Holders of at least two-thirds of
the Registrable Securities then outstanding that the Company file a registration
statement under the Securities Act covering the registration of Registrable
Securities pursuant to this Section 2.2, then the Company shall, within twenty
(20) days after the receipt of such written request, give written notice of such
request ("Request Notice") to all Holders, and effect, as soon as practicable,
the registration under the Securities Act of all Registrable Securities which
Holders request to be registered and included in such registration by written
notice given by such Holders to the Company within twenty (20) days after
receipt of the Request Notice, subject only to the limitations of this Section
2; provided that the Registrable Securities requested by all Holders to be
registered pursuant to such request must be at least twenty-five percent (25%)
of all Registrable Securities then outstanding.

                           (b) Underwriting. If the Holders initiating the
registration request under this Section 2.2 ("INITIATING HOLDERS") intend to
distribute the Registrable Securities covered by their request by means of an
underwriting, then they shall so advise the Company as a part of their request
made pursuant to this Section 2.2 and the Company shall include such information
in the written notice referred to in subsection 2.2(a). In such event, the right
of any Holder to include his 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 enter into an
underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting by the Company. Notwithstanding any
other provision of this Section 2.2, if the underwriter(s) advise(s) the Company
in writing that marketing factors require a limitation of the number of
securities to be underwritten then the Company shall so advise all Holders of
Registrable Securities that would otherwise be registered and underwritten
pursuant hereto, and the number of Registrable Securities that may be included
in the underwriting shall be reduced as required by the underwriter(s) and
allocated among the Holders of Registrable Securities on a pro rata basis
according to the number of Registrable Securities then outstanding held by each
Holder requesting registration (including the Initiating Holders); provided,
however, that the number of shares of Registrable Securities to be included in
such underwriting and registration shall not be reduced unless all other
securities of the Company are first entirely excluded from the underwriting and
registration. Any Registrable Securities excluded and withdrawn from such
underwriting shall be withdrawn from the registration.

                           (c) Maximum Number of Demand Registrations. The
Company is obligated to effect only two (2) such registrations pursuant to this
Section 2.2.

                           (d) Deferral. Notwithstanding the foregoing, if the
Company shall furnish to Holders requesting the filing of a registration
statement pursuant to this Section 2.2, a certificate signed by the President or
Chief Executive Officer of the Company stating that in the


                                       4
<PAGE>   5


good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its stockholders for such registration
statement to be filed and it is therefore essential to defer the filing of such
registration statement, then the Company shall have the right to defer such
filing for a period of not more than one hundred twenty (120) 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 (12) month period.

                           (e) Expenses. All expenses incurred in connection
with a registration pursuant to this Section 2.2, including without limitation
all registration and qualification fees, printers' and accounting fees, fees and
disbursements of counsel for the Company, and the reasonable fees and
disbursements of one counsel for the selling Holders (but excluding
underwriters' discounts and commissions), shall be borne by the Company. Each
Holder participating in a registration pursuant to this Section 2.2 shall bear
such Holder's proportionate share (based on the total number of shares sold in
such registration other than for the account of the Company) of all discounts,
commissions or other amounts payable to underwriters or brokers in connection
with such offering. Notwithstanding the foregoing, the Company shall not be
required to pay for any expenses of any registration proceeding begun pursuant
to this Section 2.2 if the registration request is subsequently withdrawn at the
request of the Holders of a majority of the Registrable Securities to be
registered, unless the Holders of a majority of the Registrable Securities then
outstanding agree to forfeit their right to one (1) demand registration pursuant
to this Section 2.2 (in which case such right shall be forfeited by all Holders
of Registrable Securities); provided, further, however, that if at the time of
such withdrawal, the Holders have learned of a material adverse change in the
condition, business, or prospects of the Company not known to the Holders at the
time of their request for such registration and have withdrawn their request for
registration with reasonable promptness after learning of such material adverse
change, then the Holders shall not be required to pay any of such expenses and
shall retain their rights pursuant to this Section 2.2.

                  2.3 Piggyback Registrations. The Company shall notify all
Holders of Registrable Securities in writing at least thirty (30) days prior to
filing any registration statement under the Securities Act for purposes of
effecting a public offering of securities of the Company (including, but not
limited to, registration statements relating to secondary offerings of
securities of the Company, but excluding registration statements relating to any
registration under Section 2.2 or Section 2.4 of this Agreement or to any
employee benefit plan or a corporate reorganization) and will afford each such
Holder an opportunity to include in such registration statement all or any part
of the Registrable Securities then held by such Holder. Each Holder desiring to
include in any such registration statement all or any part of the Registrable
Securities held by such Holder shall, within twenty (20) days after receipt of
the above-described notice from the Company, so notify the Company in writing,
and in such notice shall inform the Company of the number of Registrable
Securities such Holder wishes to include in such registration statement. If a
Holder decides not to include all of its Registrable Securities in any
registration statement thereafter filed by the Company, such Holder shall
nevertheless continue to have the right to include any Registrable Securities in
any subsequent registration statement or registration statements as may be filed
by the Company with respect to offerings of its securities, all upon the terms
and conditions set forth herein.


                                       5
<PAGE>   6


                           (a) Underwriting. If a registration statement under
which the Company gives notice under this Section 2.3 is for an underwritten
offering, then the Company shall so advise the Holders of Registrable
Securities. In such event, the right of any such Holder's Registrable Securities
to be included in a registration pursuant to this Section 2.3 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein. All Holders proposing to distribute their Registrable
Securities through such underwriting shall enter into an underwriting agreement
in customary form with the managing underwriter or underwriter(s) selected for
such underwriting. Notwithstanding any other provision of this Agreement, if the
managing underwriter determine(s) in good faith that marketing factors require a
limitation of the number of shares to be underwritten, then the managing
underwriter(s) may exclude shares (including Registrable Securities) from the
registration and the underwriting, and the number of shares that may be included
in the registration and the underwriting shall be allocated, first, to
stockholders exercising any demand registration rights, second to the Company,
and third, to each of the Holders requesting inclusion of their Registrable
Securities in such registration statement on a pro rata basis based on the total
number of Registrable Securities then held by each such Holder; provided
however, that the right of the underwriters to exclude shares (including
Registrable Securities) from the registration and underwriting as described
above shall be restricted so that: (i) the number of Registrable Securities
included in any such registration is not reduced below twenty-five percent (25%)
of the shares included in the registration, except for a registration relating
to the Company's initial public offering or an offering solely by stockholders
of the Company exercising demand registration rights, from which all Registrable
Securities may be excluded, and (ii) all shares that are not Registrable
Securities and are held by persons who are employees or directors of the Company
(or any subsidiary of the Company) shall first be excluded from such
registration and underwriting before any Registrable Securities are so excluded.
If any Holder disapproves of the terms of any such underwriting, such Holder may
elect to withdraw therefrom by written notice to the Company and the
underwriter, delivered at least twenty (20) days prior to the effective date of
the registration statement. Any Registrable Securities excluded or withdrawn
from such underwriting shall be excluded and withdrawn from the registration.
For any Holder that is a partnership or corporation, the partners, retired
partners and stockholders 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 "Holder," and any pro rata
reduction with respect to such "Holder" shall be based upon the aggregate amount
of shares carrying registration rights owned by all entities and individuals
included in such "Holder," as defined in this sentence.

                           (b) Expenses. All expenses incurred in connection
with a registration pursuant to this Section 2.3 (excluding underwriters' and
brokers' discounts and commissions), including, without limitation all federal
and "blue sky" registration and qualification fees, printers' and accounting
fees, fees and disbursements of counsel for the Company and reasonable fees and
disbursements of one counsel for the selling Holders shall be borne by the
Company.

                  2.4 Form S-3 Registration. In case the Company shall receive
from any Holder or Holders of at least twenty-five percent (25%) of all
Registrable Securities then outstanding a written request or requests that the
Company effect a registration on Form S-3 and any related


                                       6
<PAGE>   7


qualification or compliance with respect to all or a part of the Registrable
Securities owned by such Holder or Holders, then the Company will:

                           (a) Notice. Promptly give written notice of the
proposed registration and the Holder's or Holders' request therefor, and any
related qualification or compliance, to all other Holders of Registrable
Securities; and

                           (b) Registration. As soon as practicable, effect 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 twenty (20) 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 2.4:

                                     (i)    if Form S-3 is not available for
such offering;

                                     (ii)   if the Holders, together with the
holders of any other securities of the Company entitled to inclusion in such
registration, propose to sell Registrable Securities and such other securities
(if any) at an aggregate price to the public of less than $1,000,000;

                                     (iii)  if the Company shall furnish to the
Holders a certificate signed by the President or Chief Executive Officer of the
Company stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its stockholders
for such Form S-3 Registration to be effected at such time, in which event the
Company shall have the right to defer the filing of the Form S-3 registration
statement no more than once during any twelve month period for a period of not
more than 120 days after receipt of the request of the Holder or Holders under
this Section 2.4;

                                     (iv)   if the Company has, within the
twelve (12) month period preceding the date of such request, already effected
two (2) registrations on Form S-3 for the Holders pursuant to this Section 2.4;
or

                                     (v)    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) Expenses. Subject to the foregoing, the Company
shall file a Form S-3 registration statement covering the Registrable Securities
and other securities so requested to be registered pursuant to this Section 2.4
as soon as practicable after receipt of the request or requests of the Holders
for such registration. The Company shall pay all expenses incurred in connection
with each registration requested pursuant to this Section 2.4, (excluding
underwriters' or brokers' discounts and commissions), including without
limitation all filing,


                                       7
<PAGE>   8


registration and qualification, printers' and accounting fees and the reasonable
fees and disbursements of one counsel for the selling Holder or Holders and
counsel for the Company.

                           (d) Not Demand Registration. Form S-3 registrations
shall not be deemed to be demand registrations as described in Section 2.2
above.

                  2.5      Obligations of the Company. Whenever required to
effect the registration of any Registrable Securities under this Agreement, 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 reasonable,
diligent 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, keep such registration statement effective for up to
ninety (90) days.

                           (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 Securities Act with respect to the disposition of all
securities covered by such registration statement.

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

                           (d) Use reasonable, diligent 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 qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions.

                           (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(s) 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 Securities 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.

                           (g) Furnish, at the request of any Holder requesting
registration of Registrable Securities, on the date that such Registrable
Securities are delivered to the underwriters for sale, if such securities are
being sold through underwriters, or, if such securities


                                       8
<PAGE>   9


are not being sold through underwriters, on the date that the registration
statement with respect to such securities becomes effective, (i) an opinion,
dated as of 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 and reasonably satisfactory to a
majority in interest of the Holders requesting registration, addressed to the
underwriters, if any, and to the Holders requesting registration of Registrable
Securities and (ii) a "comfort" letter dated as of 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 and reasonably satisfactory to a
majority in interest of the Holders requesting registration, addressed to the
underwriters, if any, and to the Holders requesting registration of Registrable
Securities.

                  2.6 Furnish Information. It shall be a condition precedent to
the obligations of the Company to take any action pursuant to Sections 2.2, 2.3
or 2.4 that the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be required to timely effect
the registration of their Registrable Securities.

                  2.7 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 2.

                  2.8 Indemnification. In the event any Registrable Securities
are included in a registration statement under Sections 2.2, 2.3 or 2.4:

                           (a) By the Company. To the extent permitted by law,
the Company will indemnify and hold harmless each Holder, the partners, officers
and directors of each Holder, any underwriter (as defined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Securities Exchange Act of 1934,
as amended, (the "1934 ACT"), against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the
Securities Act, the l934 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, "VIOLATIONS" and, individually, 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 Securities Act, the 1934 Act, any federal or state
securities law or any rule or regulation promulgated under the Securities Act,
the 1934 Act or any federal or state securities law in connection with the
offering covered by such registration statement; and the Company will


                                       9
<PAGE>   10


reimburse each such Holder, partner, officer or director, underwriter or
controlling person for any legal or other expenses reasonably incurred by them,
as incurred, in connection with investigating or defending any such loss, claim,
damage, liability or action; provided however, that the indemnity agreement
contained in this subsection 2.8(a) 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 Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable 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 such Holder, partner, officer, director, underwriter
or controlling person of such Holder.

                           (b) By Selling Holders. To the extent permitted by
law, each selling Holder will indemnify and hold harmless the Company, each of
its directors, each of its officers who have signed the registration statement,
each person, if any, who controls the Company within the meaning of the
Securities Act, any underwriter and any other Holder selling securities under
such registration statement or any of such other Holder's partners, directors or
officers or any person who controls such Holder within the meaning of the
Securities Act or the 1934 Act, against any losses, claims, damages or
liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, partner or
director, officer or controlling person of such other Holder may become subject
under the Securities 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 reimburse any
legal or other expenses reasonably incurred by the Company or any such director,
officer, controlling person, underwriter or other Holder, partner, officer,
director or controlling person of such other Holder in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the indemnity agreement contained in this subsection
2.8(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, that the total amounts payable in indemnity by a Holder under this
Section 2.8(b) in respect of any Violation shall not exceed the net proceeds
received by such Holder in the registered offering out of which such Violation
arises.

                           (c) Notice. Promptly after receipt by an indemnified
party under this Section 2.8 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
2.8, 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; provided, however, that an indemnified
party shall have the right to retain its own 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


                                       10
<PAGE>   11


conflict of 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 2.8, 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 2.8.

                           (d) Defect Eliminated in Final Prospectus. The
foregoing indemnity agreements of the Company and Holders are subject to the
condition that, insofar as they relate to any Violation made in a preliminary
prospectus but eliminated or remedied in the amended prospectus on file with the
SEC at the time the registration statement in question becomes effective or the
amended prospectus filed with the SEC pursuant to SEC Rule 424(b) (the "FINAL
PROSPECTUS"), such indemnity agreement shall not inure to the benefit of any
person if a copy of the Final Prospectus was furnished to the indemnified party
and was not furnished to the person asserting the loss, liability, claim or
damage at or prior to the time such action is required by the Securities Act.

                           (e) Contribution. In order to provide for just and
equitable contribution to joint liability under the Securities Act in any case
in which either (i) any Holder exercising rights under this Agreement, or any
controlling person of any such Holder, makes a claim for indemnification
pursuant to this Section 2.8 but it is judicially determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
this Section 2.8 provides for indemnification in such case, or (ii) contribution
under the Securities Act may be required on the part of any such selling Holder
or any such controlling person in circumstances for which indemnification is
provided under this Section 2.8; then, and in each such case, the Company and
such Holder will contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (after contribution from others) in
such proportion so that such Holder is responsible for the portion represented
by the percentage that the public offering price of its Registrable Securities
offered by and sold under the registration statement bears to the public
offering price of all securities offered by and sold under such registration
statement, and the Company and other selling Holders are responsible for the
remaining portion; provided, however, that, in any such case, (A) no such Holder
will be required to contribute any amount in excess of the public offering price
of all such Registrable Securities offered and sold by such Holder pursuant to
such registration statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
will be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.

                           (f) Survival. The obligations of the Company and
Holders under this Section 2.8 shall survive the completion of any offering of
Registrable Securities in a registration statement, and otherwise.

                  2.9 "Market Stand-Off" Agreement. Each Holder hereby agrees
that it shall not, to the extent requested by the Company or an underwriter of
securities of the Company, sell


                                       11
<PAGE>   12


or otherwise transfer or dispose of any Registrable Securities or other shares
of stock of the Company then owned by such Holder (other than to donees or
partners of the Holder who agree to be similarly bound) for up to one hundred
eighty (180) days following the effective date of a registration statement of
the Company filed under the Securities Act; provided, however, that:

                           (a) such agreement shall be applicable only to the
first such registration statement of the Company which covers securities to be
sold on its behalf to the public in an underwritten offering but not to
Registrable Securities sold pursuant to such registration statement; and

                           (b) all officers and directors of the Company then
holding Common Stock of the Company enter into similar agreements.

In order to enforce the foregoing covenant, the Company shall have the right to
place restrictive legends on the certificates representing the shares subject to
this Section and to impose stop transfer instructions with respect to the
Registrable Securities and such other shares of stock of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

                  2.10 Rule 144 Reporting. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Registrable Securities to the public without
registration, after such time as a public market exists for the Common Stock of
the Company, the Company agrees to:

                           (a) Make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act, at
all times after the effective date of the first registration under the
Securities Act filed by the Company for an offering of its securities to the
general public;

                           (b) Use reasonable, diligent efforts to file with the
Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the 1934 Act (at any time after it has
become subject to such reporting requirements); and

                           (c) So long as a Holder owns any Registrable
Securities, to furnish to the Holder forthwith upon request a written statement
by the Company as to its compliance with the reporting requirements of said Rule
144 (at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the 1934 Act (at any time
after it has become subject to the reporting requirements of the 1934 Act), a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents of the Company as a Holder may reasonably request in
availing itself of any rule or regulation of the Commission allowing a Holder to
sell any such securities without registration (at any time after the Company has
become subject to the reporting requirements of the 1934 Act).

                  2.11 Termination of the Company's Obligations. The Company
shall have no obligations pursuant to Sections 2.2 through 2.4 with respect to
any request or requests for


                                       12
<PAGE>   13


registration made by any Holder on a date more than five (5) years after the
closing date of the Company's initial public offering. Notwithstanding anything
to the contrary contained in Section 2.2 or 2.4, if any Holder is eligible to
sell Registrable Securities pursuant Rule 144(k) or any successor provision
under the Securities Act (an "Excluded Holder"), the Registrable Securities of
such Excluded Holder shall be disregarded in determining the requisite
percentage of Registrable Securities that are required to initiate a
registration pursuant to Section 2.2 or 2.4 (i.e., a registration under Section
2.2 must be initiated by persons holding at least two-thirds of the Registrable
Securities held by all Holders who are not Excluded Holders and a registration
under Section 2.4 must be initiated by persons holding at least 25% of the
Registrable Securities held by all Holders who are not Excluded Holders). After
a registration has been requested pursuant to Section 2.2 or 2.4, as the case
may be, by the requisite percentage of shares held by Holders who are not
Excluded Holders, all Holders (including Excluded Holders) shall be entitled to
include their Registrable Securities in such registration subject to the terms
and conditions of this Agreement.

                  2.12 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 Registrable Securities then
outstanding, 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
2.2 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 his 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
2.2(a), or within one hundred twenty (120) days of the effective date of any
registration effected pursuant to Section 2.2.

         3.       PRE-EMPTIVE RIGHTS.

                  3.1 General. Each Holder (as defined in Section 2.1(d)) and
any party to whom such Holder's rights under this Section 3 have been duly
assigned in accordance with Section 4.1(b) (each such Holder or assignee being
hereinafter referred to as a "RIGHTS HOLDER") has the right of first refusal to
purchase such Rights Holder's Pro Rata Share (as defined below), of all (or any
part) of any "New Securities" (as defined in Section 3.2) that the Company may
from time to time issue after the date of this Agreement. A Rights Holder's "PRO
RATA SHARE" for purposes of this right of first refusal is the ratio of (a) the
number of Registrable Securities as to which such Rights Holder is the Holder
(and/or is deemed to be the Holder under Section 2.1(d)), to (b) a number of
shares of Common Stock of the Company equal to the sum of (i) the total number
of shares of Common Stock of the Company then outstanding plus (ii) the total
number of shares of Common Stock of the Company into which all then outstanding
shares of Preferred Stock of the Company are then convertible.

                  3.2 New Securities. "NEW SECURITIES" shall mean any Common
Stock or Preferred Stock of the Company, whether now authorized or not, and
rights, options or warrants to purchase such Common Stock or Preferred Stock,
and securities of any type whatsoever that


                                       13
<PAGE>   14


are, or may become, convertible or exchangeable into such Common Stock or
Preferred Stock; provided, however, that the term "New Securities" does not
include:

                           (a) up to 3,500,000 shares of the Company's Common
Stock (and/or options or warrants therefor) issued to employees, officers,
directors, contractors, advisors or consultants of the Company pursuant to
incentive agreements or plans approved by the Board of Directors of the Company;

                           (b) any shares of Series C Stock issued under the
Purchase Agreement, as such agreement may be amended.

                           (c) any securities issuable upon conversion of or
with respect to any then outstanding shares of Series A Stock, Series B Stock or
Series C Stock of the Company or Common Stock or other securities issuable upon
conversion thereof;

                           (d) any securities issuable upon exercise of any
options, warrants or rights to purchase any securities of the Company
outstanding on the date of this Agreement ("WARRANT SECURITIES") and any
securities issuable upon the conversion of any Warrant Securities or upon the
exercise or conversion of any securities, if such securities were first offered
to the Rights Holders hereunder;

                           (e) shares of the Company's Common Stock or Preferred
Stock issued in connection with any stock split or stock dividend;

                           (f) securities offered by the Company to the public
pursuant to a registration statement filed under the Securities Act;

                           (g) up to 250,000 shares of the Company's Common
Stock or Preferred Stock (and/or options or warrants therefor) issued or
issuable to parties providing the Company with equipment leases, real property
leases, loans, credit lines, guaranties of indebtedness, cash price reductions
or similar financing such number of shares being subject to proportional
adjustment to reflect subdivisions, combinations and stock dividends affecting
the number of outstanding shares of such stock; or

                           (h) securities issued pursuant to the acquisition of
another corporation or entity by the Company by consolidation, merger, purchase
of all or substantially all of the assets, or other reorganization in which the
Company acquires, in a single transaction or series of related transactions, all
or substantially all of the assets of such other corporation or entity or fifty
percent (50%) or more of the voting power of such other corporation or entity or
fifty percent (50%) or more of the equity ownership of such other entity.

                  3.3 Procedures. In the event that the Company proposes to
undertake an issuance of New Securities, it shall give to each Rights Holder
written notice of its intention to issue New Securities (the "NOTICE"),
describing the type of New Securities and the price and the general terms upon
which the Company proposes to issue such New Securities. Each Rights Holder
shall have ten (10) days from the date of mailing of any such Notice to agree in
writing to purchase such Rights Holder's Pro Rata Share of such New Securities
for the price and upon the


                                       14
<PAGE>   15


general terms specified in the Notice by giving written notice to the Company
and stating therein the quantity of New Securities to be purchased (not to
exceed such Rights Holder's Pro Rata Share). If any Rights Holder fails to so
agree in writing within such ten (10) day period to purchase such Rights
Holder's full Pro Rata Share of an offering of New Securities (a "NONPURCHASING
HOLDER"), then such Nonpurchasing Holder shall forfeit the right hereunder to
purchase that part of his Pro Rata Share of such New Securities that he did not
so agree to purchase and the Company shall promptly give each Rights Holder who
has timely agreed to purchase his full Pro Rata Share of such offering of New
Securities (a "PURCHASING HOLDER") written notice of the failure of any
Nonpurchasing Holder to purchase such Nonpurchasing Rights Holder's full Pro
Rata Share of such offering of New Securities (the "OVERALLOTMENT NOTICE"). Each
Purchasing Holder shall have a right of overallotment such that such Purchasing
Holder may agree to purchase a portion of the Nonpurchasing Holders' unpurchased
Pro Rata Shares of such offering on a pro rata basis according to the relative
Pro Rata Shares of the Purchasing Rights Holders, at any time within five (5)
days after receiving the Overallotment Notice.

                  3.4 Failure to Exercise. In the event that the Rights Holders
fail to exercise in full the right of first refusal within such ten (10) plus
five (5) day period, then the Company shall have 120 days thereafter to sell the
New Securities with respect to which the Rights Holders' rights of first refusal
hereunder were not exercised, at a price and upon general terms not materially
more favorable to the purchasers thereof than specified in the Company's Notice
to the Rights Holders. In the event that the Company has not issued and sold the
New Securities within such 120-day period, then the Company shall not thereafter
issue or sell any New Securities without again first offering such New
Securities to the Rights Holders pursuant to this Section 3.

                  3.5 Termination. This right of first refusal shall terminate
(a) immediately before the closing of the first underwritten sale of Common
Stock of the Company to the public pursuant to a registration statement filed
with, and declared effective by, the SEC under the Securities Act, covering the
offer and sale of Common Stock to the public at an offering price of at least
$1.10 per share (such offering price being subject to proportional adjustment to
reflect subdivisions, combinations, stock dividends and similar transactions
affecting the number of outstanding shares of Common Stock) for an aggregate
gross public offering price (calculated before deduction of underwriters'
discounts and commissions) of at least $15,000,000 or (b) upon (i) the
acquisition of all or substantially all the assets of the Company or (ii) an
acquisition of the Company by another corporation or entity by consolidation,
merger or other reorganization in which the holders of the Company's outstanding
voting stock immediately prior to such transaction own, immediately after such
transaction, securities representing less than fifty percent (50%) or more of
the voting power of the corporation or other entity surviving such transaction.

         4.       ASSIGNMENT AND AMENDMENT.

                  4.1 Assignment. Notwithstanding anything herein to the
 contrary:

                           (a) Information Rights. The rights of an Investor
under Section 1.1 or 1.2 or 1.4 hereof may be assigned only to (i) a party who
acquires from an Investor (or an Investor's permitted assigns) at least 500,000
shares of Series A Stock, Series B Stock or Series C Stock subject to this
Agreement and/or an equivalent number (on an as-converted basis) of


                                       15
<PAGE>   16


Registrable Securities issued upon conversion thereof or (ii) a partner, member
or stockholder of an Investor who acquires at least 100,000 shares of Series A
Stock, Series B Stock, or Series C Stock subject to this Agreement and/or an
equivalent number (on an as-converted basis) of Registrable Securities issued
upon conversion.

                           (b) Registration Rights; Refusal Rights. The
registration rights of a Holder under Section 2 hereof and the rights of first
refusal of a Rights Holder under Section 3 hereof may be assigned only to (i) a
party who acquires at least 500,000 shares of Series A Stock, Series B Stock or
Series C Stock subject to this Agreement and/or an equivalent number (on an
as-converted basis) of Registrable Securities issued upon conversion thereof or
(ii) any partner, member or shareholder of an Investor or permitted transferee
thereof; provided, however that no party may be assigned any of the foregoing
rights unless the Company is given written notice by the assigning party at the
time of such assignment stating the name and address of the assignee and
identifying the securities of the Company as to which the rights in question are
being assigned; and provided further that any such assignee shall receive such
assigned rights subject to all the terms and conditions of this Agreement,
including without limitation the provisions of this Section 4.

                  4.2 Amendment of Rights. Any provision of this Agreement may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and Investors (and/or any of their permitted
successors or assigns) holding shares of Series A Stock, Series B Stock, Series
C Stock and/or Conversion Stock representing and/or convertible into a majority
of all the Investors' Shares (as defined below). As used herein, the term
"INVESTORS' SHARES" shall mean the shares of Common Stock then issuable upon
conversion of all then outstanding shares of Series A Stock, Series B Stock and
Series C Stock subject to this Agreement plus all then outstanding shares of
Conversion Stock that were issued upon the conversion of any shares of Series A

        exercise or conversion of then outstanding and then exercisable options,
        warrants or convertible securities.

            (d) Holder. For purposes of this Section 2 and Sections 3 and 4
        hereof, the term "HOLDER" means any person owning of record Registrable
        Securities that have not been sold to the public or pursuant to Rule 144
        promulgated under the Securities Act or any assignee of record of such
        Registrable Securities to whom rights under such Sections have been duly
        assigned in accordance with this Agreement; provided, however, that for
        purposes of this Agreement, a record holder of the Warrant or shares of
        Series A Stock, Series B Stock or Series C Stock convertible into such
        Registrable Securities shall be deemed to be the Holder of such
        Registrable Securities; and provided, further, that the Company shall in
        no event be obligated to register the Warrant or shares of Series A
        Stock, Series B Stock, or Series C Stock and that Holders of Registrable
        Securities will not be required to convert the Warrant or their shares
        of Series A Stock, Series B Stock or Series C Stock into Common Stock in
        order to exercise the registration rights granted hereunder, until
        immediately before the closing of the offering to which the registration
        relates.

            (e) Form S-3. The term "FORM S-3" means such form under the
        Securities Act as is in effect on the date hereof or any successor
        registration form under the Securities Act subsequently adopted by the
        SEC which permits inclusion or incorporation of substantial information
        by reference to other documents filed by the Company with the SEC.

            (f) SEC. The term "SEC" or "COMMISSION" means the U.S. Securities
        and Exchange Commission.

            (g) Series A Stock. The term "SERIES A STOCK" shall mean the
        Company's Series A Preferred Stock, par value $0.001 per share.

            (h) Series B Stock. The term "SERIES B STOCK" shall mean the
        Company's Series B Preferred Stock, par value $0.001 per share.

            (i) Series C Stock. The term "SERIES C STOCK" shall mean the
        Company's Series C Preferred Stock, par value $0.001 per share.

        2.2 Demand Registration.

            (a) Request by Holders. If the Company shall receive at any time
        after six (6) months after the effective date of the Company's initial
        public offering of its securities pursuant to a registration filed under
        the Securities Act, a written request from the Holders of at least
        two-thirds of the Registrable Securities then outstanding that the
        Company file a registration statement under the Securities Act covering
        the registration of Registrable Securities pursuant to this Section 2.2,
        then the

                                  CONFIDENTIAL                      Page 2 of 14

<PAGE>   3


        Company shall, within twenty (20) days after the receipt of such written
        request, give written notice of such request ("REQUEST NOTICE") to all
        Holders, and effect, as soon as practicable, the registration under the
        Securities Act of all Registrable Securities which Holders request to be
        registered and included in such registration by written notice given by
        such Holders to the Company within twenty (20) days after receipt of the
        Request Notice, subject only to the limitations of this Section 2;
        provided that the Registrable Securities requested by all Holders to be
        registered pursuant to such request must be at least twenty-five percent
        (25%) of all Registrable Securities then outstanding.

            (b) Underwriting. If the Holders initiating the registration request
        under this Section 2.2 ("INITIATING HOLDERS") intend to distribute the
        Registrable Securities covered by their request by means of an
        underwriting, then they shall so advise the Company as a part of their
        request made pursuant to this Section 2.2 and the Company shall include
        such information in the written notice referred to in subsection 2.2(a).
        In such event, the right of any Holder to include his 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 enter into
        an underwriting agreement in customary form with the managing
        underwriter or underwriters selected for such underwriting by the
        Company. Notwithstanding any other provision of this Section 2.2, if the
        underwriter(s) advise(s) the Company in writing that marketing factors
        require a limitation of the number of securities to be underwritten then
        the Company shall so advise all Holders of Registrable Securities that
        would otherwise be registered and underwritten pursuant hereto, and the
        number of Registrable Securities that may be included in the
        underwriting shall be reduced as required by the underwriter(s) and
        allocated among the Holders of Registrable Securities on a pro rata
        basis according to the number of Registrable Securities then outstanding
        held by each Holder requesting registration (including the Initiating
        Holders); provided, however, that the number of shares of Registrable
        Securities to be included in such underwriting and registration shall
        not be reduced unless all other securities of the Company are first
        entirely excluded from the underwriting and registration. Any
        Registrable Securities excluded and withdrawn from such underwriting
        shall be withdrawn from the registration.

            (c) Maximum Number of Demand Registrations. The Company is obligated
        to effect only two (2) such registrations pursuant to this Section 2.2.

            (d) Deferral. Notwithstanding the foregoing, if the Company shall
        furnish to Holders requesting the filing of a registration statement
        pursuant to this Section 2.2, a certificate signed by the President or
        Chief Executive Officer of the Company stating that in the good faith
        judgment of the Board of Directors of the Company, it would be seriously
        detrimental to the Company and its stockholders for such registration
        statement to be filed and it is therefore essential to defer the filing
        of such registration statement, then the Company shall have the right to
        defer such filing for a period of not more than one hundred twenty (120)
        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 (12) month period.

            (e) Expenses. All expenses incurred in connection with a
        registration pursuant to this Section 2.2, including without limitation
        all registration and qualification fees, printers' and accounting fees,
        fees and disbursements of counsel for the Company, and the reasonable
        fees and disbursements of one counsel for the selling Holders (but
        excluding underwriters' discounts and commissions), shall be borne by
        the Company. Each Holder participating in a registration pursuant to
        this Section 2.2 shall bear such Holder's proportionate share (based on
        the total number of shares sold in such registration other than for the
        account of the Company) of all discounts, commissions or other amounts
        payable to underwriters or brokers in connection with such offering.
        Notwithstanding the foregoing, the Company shall not be required to pay
        for any expenses of any registration proceeding

                                  CONFIDENTIAL                      Page 3 of 14

<PAGE>   4


        begun pursuant to this Section 2.2 if the registration request is
        subsequently withdrawn at the request of the Holders of a majority of
        the Registrable Securities to be registered, unless the Holders of a
        majority of the Registrable Securities then outstanding agree to forfeit
        their right to one (1) demand registration pursuant to this Section 2.2
        (in which case such right shall be forfeited by all Holders of
        Registrable Securities); provided, further, however, that if at the time
        of such withdrawal, the Holders have learned of a material adverse
        change in the condition, business, or prospects of the Company not known
        to the Holders at the time of their request for such registration and
        have withdrawn their request for registration with reasonable promptness
        after learning of such material adverse change, then the Holders shall
        not be required to pay any of such expenses and shall retain their
        rights pursuant to this Section 2.2.

        2.3 Piggyback Registrations. The Company shall notify all Holders of
     Registrable Securities in writing at least thirty (30) days prior to filing
     any registration statement under the Securities Act for purposes of
     effecting a public offering of securities of the Company (including, but
     not limited to, registration statements relating to secondary offerings of
     securities of the Company, but excluding registration statements relating
     to any registration under Section 2.2 or Section 2.4 of this Agreement or
     to any employee benefit plan or a corporate reorganization) and will afford
     each such Holder an opportunity to include in such registration statement
     all or any part of the Registrable Securities then held by such Holder.
     Each Holder desiring to include in any such registration statement all or
     any part of the Registrable Securities held by such Holder shall, within
     twenty (20) days after receipt of the above-described notice from the
     Company, so notify the Company in writing, and in such notice shall inform
     the Company of the number of Registrable Securities such Holder wishes to
     include in such registration statement. If a Holder decides not to include
     all of its Registrable Securities in any registration statement thereafter
     filed by the Company, such Holder shall nevertheless continue to have the
     right to include any Registrable Securities in any subsequent registration
     statement or registration statements as may be filed by the Company with
     respect to offerings of its securities, all upon the terms and conditions
     set forth herein.

            (a) Underwriting. If a registration statement under which the
        Company gives notice under this Section 2.3 is for an underwritten
        offering, then the Company shall so advise the Holders of Registrable
        Securities. In such event, the right of any such Holder's Registrable
        Securities to be included in a registration pursuant to this Section 2.3
        shall be conditioned upon such Holder's participation in such
        underwriting and the inclusion of such Holder's Registrable Securities
        in the underwriting to the extent provided herein. All Holders proposing
        to distribute their Registrable Securities through such underwriting
        shall enter into an underwriting agreement in customary form with the
        managing underwriter or underwriter(s) selected for such underwriting.
        Notwithstanding any other provision of this Agreement, if the managing
        underwriter determine(s) in good faith that marketing factors require a
        limitation of the number of shares to be underwritten, then the managing
        underwriter(s) may exclude shares (including Registrable Securities)
        from the registration and the underwriting, and the number of shares
        that may be included in the registration and the underwriting shall be
        allocated, first, to stockholders exercising any demand registration
        rights, second to the Company, and third, to each of the Holders
        requesting inclusion of their Registrable Securities in such
        registration statement on a pro rata basis based on the total number of
        Registrable Securities then held by each such Holder; provided however,
        that the right of the underwriters to exclude shares (including
        Registrable Securities) from the registration and underwriting as
        described above shall be restricted so that: (i) the number of
        Registrable Securities included in any such registration is not reduced
        below twenty-five percent (25%) of the shares included in the
        registration, except for a registration relating to the Company's
        initial public offering or an offering solely by stockholders of the
        Company exercising demand registration rights, from which all
        Registrable Securities may be excluded, and (ii) all shares that are not
        Registrable Securities and are held by persons who are employees or
        directors of the Company (or any subsidiary of the Company) shall first
        be excluded from such registration and underwriting before any
        Registrable Securities are so excluded. If any Holder disapproves of the
        terms of any such underwriting, such Holder may elect to withdraw
        therefrom by written notice to the Company and the underwriter,
        delivered at least twenty (20) days prior to the effective date of the
        registration statement. Any Registrable Securities excluded or withdrawn
        from such underwriting shall be excluded and withdrawn from the
        registration. For any Holder that is a partnership or corporation, the
        partners, retired partners and stockholders 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 "Holder," and any pro rata reduction with respect
        to such "Holder" shall be based upon the aggregate amount of shares
        carrying registration rights owned by all entities and individuals
        included in such "Holder," as defined in this sentence.

<PAGE>   5


            (b) Expenses. All expenses incurred in connection with a
        registration pursuant to this Section 2.3 (excluding underwriters' and
        brokers' discounts and commissions), including, without limitation all
        federal and "blue sky" registration and qualification fees, printers'
        and accounting fees, fees and disbursements of counsel for the Company
        and reasonable fees and disbursements of one counsel for the selling
        Holders shall be borne by the Company.

        2.4 Form S-3 Registration. In case the Company shall receive from any
     Holder or Holders of at least twenty-five percent (25%) of all 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, then the Company will:

            (a) Notice. Promptly give written notice of the proposed
        registration and the Holder's or Holders' request therefor, and any
        related qualification or compliance, to all other Holders of Registrable
        Securities; and

            (b) Registration. As soon as practicable, effect 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 twenty (20)
        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 2.4:

                (i) if Form S-3 is not available for such offering;

                (ii) if the Holders, together with the holders of any other
            securities of the Company entitled to inclusion in such
            registration, propose to sell Registrable Securities and such other
            securities (if any) at an aggregate price to the public of less than
            $1,000,000;

                (iii) if the Company shall furnish to the Holders a certificate
            signed by the President or Chief Executive Officer of the Company
            stating that in the good faith judgment of the Board of Directors of
            the Company, it would be seriously detrimental to the Company and
            its stockholders for such Form S-3 Registration to be effected at
            such time, in which event the Company shall have the right to defer
            the filing of the Form S-3 registration statement no more than once
            during any twelve month period for a period of not more than 120
            days after receipt of the request of the Holder or Holders under
            this Section 2.4;

                (iv) if the Company has, within the twelve (12) month period
            preceding the date of such request, already effected two (2)
            registrations on Form S-3 for the Holders pursuant to this Section
            2.4; or

                (v) 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) Expenses. Subject to the foregoing, the Company shall file a
        Form S-3 registration statement covering the Registrable Securities and
        other securities so requested to be registered pursuant to this Section
        2.4 as soon as practicable after receipt of the request or requests of
        the Holders for such registration. The Company shall pay all expenses
        incurred in connection with each registration requested pursuant to this
        Section 2.4, (excluding underwriters' or brokers' discounts and
        commissions), including without limitation all filing, registration and
        qualification, printers' and accounting fees and the reasonable fees and
        disbursements of one counsel for the selling Holder or Holders and
        counsel for the Company.

            (d) Not Demand Registration. Form S-3 registrations shall not be
        deemed to be demand registrations as described in Section 2.2 above.

        2.5 Obligations of the Company. Whenever required to effect the
     registration of any Registrable Securities under this Agreement, 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 reasonable, diligent
        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, keep such registration statement
        effective for up to ninety (90) days.

                                  CONFIDENTIAL                      Page 5 of 14


<PAGE>   6


            (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 Securities Act with respect to the disposition of all
        securities covered by such registration statement.

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

            (d) Use reasonable, diligent 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 qualify to
        do business or to file a general consent to service of process in any
        such states or jurisdictions.

            (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(s) 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 Securities 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.

            (g) Furnish, at the request of any Holder requesting registration of
        Registrable Securities, on the date that such Registrable Securities are
        delivered to the underwriters for sale, 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 as
        of 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 and reasonably
        satisfactory to a majority in interest of the Holders requesting
        registration, addressed to the underwriters, if any, and to the Holders
        requesting registration of Registrable Securities and (ii) a "comfort"
        letter dated as of 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 and reasonably satisfactory to a majority
        in interest of the Holders requesting registration, addressed to the
        underwriters, if any, and to the Holders requesting registration of
        Registrable Securities.

        2.6 Furnish Information. It shall be a condition precedent to the
     obligations of the Company to take any action pursuant to Sections 2.2, 2.3
     or 2.4 that the selling Holders shall furnish to the Company such
     information regarding themselves, the Registrable Securities held by them,
     and the intended method of disposition of such securities as shall be
     required to timely effect the registration of their Registrable Securities.

        2.7 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 2.

        2.8 Indemnification. In the event any Registrable Securities are
     included in a registration statement under Sections 2.2, 2.3 or 2.4:

            (a) By the Company. To the extent permitted by law, the Company will
        indemnify and hold harmless each Holder, the partners, officers and
        directors of each Holder, any underwriter (as defined in the Securities
        Act) for such Holder and each person, if any, who controls such Holder
        or underwriter within the meaning of the Securities Act or the
        Securities Exchange Act of 1934, as amended, (the "1934 ACT"), against
        any losses, claims, damages, or liabilities (joint or several) to which
        they may become subject under the Securities Act, the l934 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, "VIOLATIONS" and, individually, a "VIOLATION"):

                                  CONFIDENTIAL                      Page 6 of 14

<PAGE>   7


                (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
            Securities Act, the 1934 Act, any federal or state securities law or
            any rule or regulation promulgated under the Securities Act, the
            1934 Act or any federal or state securities law in connection with
            the offering covered by such registration statement; and the Company
            will reimburse each such Holder, partner, officer or director,
            underwriter or controlling person for any legal or other expenses
            reasonably incurred by them, as incurred, in connection with
            investigating or defending any such loss, claim, damage, liability
            or action; provided however, that the indemnity agreement contained
            in this subsection 2.8(a) 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 Company
            (which consent shall not be unreasonably withheld), nor shall the
            Company be liable 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 such Holder, partner, officer, director,
            underwriter or controlling person of such Holder.

            (b) By Selling Holders. To the extent permitted by law, each selling
        Holder will indemnify and hold harmless the Company, each of its
        directors, each of its officers who have signed the registration
        statement, each person, if any, who controls the Company within the
        meaning of the Securities Act, any underwriter and any other Holder
        selling securities under such registration statement or any of such
        other Holder's partners, directors or officers or any person who
        controls such Holder within the meaning of the Securities Act or the
        1934 Act, against any losses, claims, damages or liabilities (joint or
        several) to which the Company or any such director, officer, controlling
        person, underwriter or other such Holder, partner or director, officer
        or controlling person of such other Holder may become subject under the
        Securities 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 reimburse any legal or other expenses reasonably
        incurred by the Company or any such director, officer, controlling
        person, underwriter or other Holder, partner, officer, director or
        controlling person of such other Holder in connection with investigating
        or defending any such loss, claim, damage, liability or action;
        provided, however, that the indemnity agreement contained in this
        subsection 2.8(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, that the total amounts
        payable in indemnity by a Holder under this Section 2.8(b) in respect of
        any Violation shall not exceed the net proceeds received by such Holder
        in the registered offering out of which such Violation arises.

            (c) Notice. Promptly after receipt by an indemnified party under
        this Section 2.8 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 2.8, 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;
        provided, however, that an indemnified party shall have the right to
        retain its own 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 conflict of 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 2.8,
        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 2.8.

             (d) Defect Eliminated in Final Prospectus. The foregoing indemnity
        agreements of the Company and Holders are subject to the condition that,
        insofar as they relate to any Violation made in a preliminary prospectus
        but eliminated or remedied in the amended prospectus on file with the
        SEC at the time the registration statement in question becomes effective
        or the amended prospectus filed with the SEC pursuant to SEC Rule 424(b)
        (the "FINAL PROSPECTUS"), such indemnity agreement shall not inure to
        the benefit of any person if a copy of the Final Prospectus was
        furnished to the indemnified party and was not furnished to the person
        asserting the loss, liability, claim or damage at or prior to the time
        such action is required by the Securities Act.

             (e) Contribution. In order to provide for just and equitable
        contribution to joint liability under the Securities Act in any case in
        which either (i) any Holder exercising rights under this Agreement, or
        any controlling person of any such Holder, makes a claim for
        indemnification pursuant to this Section 2.8 but it is judicially
        determined (by the entry of a final judgment or decree by a court of
        competent jurisdiction and the expiration of time to appeal or the
        denial of the last right of appeal) that such indemnification may not be
        enforced in such case notwithstanding the fact that this Section 2.8
        provides for indemnification in such case, or (ii) contribution under
        the Securities Act may be required on the part of any such selling
        Holder or any such controlling person in circumstances for which
        indemnification is provided under this Section 2.8; then, and in each
        such case, the Company and such Holder will contribute to the aggregate
        losses, claims, damages or liabilities to which they may be subject
        (after contribution from others) in such proportion so that such Holder
        is responsible for the portion represented by the percentage that the
        public offering price of its Registrable Securities offered by and sold
        under the registration statement bears to the public offering price of
        all securities offered by and sold under such registration statement,
        and the Company and other selling Holders are responsible for the
        remaining portion; provided, however, that, in any such case, (A) no
        such Holder will be required to contribute any amount in excess of the
        public offering price of all such Registrable Securities offered and
        sold by such Holder pursuant to such registration statement; and (B) no
        person or entity guilty of fraudulent misrepresentation (within the
        meaning of Section 11(f) of the Securities Act) will be entitled to
        contribution from any person or entity who was not guilty of such
        fraudulent misrepresentation.

             (f) Survival. The obligations of the Company and Holders under this
        Section 2.8 shall survive the completion of any offering of Registrable
        Securities in a registration statement, and otherwise.

        2.9 "Market Stand-Off" Agreement. Each Holder hereby agrees that it
     shall not, to the extent requested by the Company or an underwriter of
     securities of the Company, sell or otherwise transfer or dispose of any
     Registrable Securities or other shares of stock of the Company then owned
     by such Holder (other than to donees or partners of the Holder who agree to
     be similarly bound) for up to one hundred eighty (180) days following the
     effective date of a registration statement of the Company filed under the
     Securities Act; provided, however, that:

             (a) such agreement shall be applicable only to the first such
        registration statement of the Company which covers securities to be sold
        on its behalf to the public in an underwritten offering but not to
        Registrable Securities sold pursuant to such registration statement; and

             (b) all officers and directors of the Company then holding Common
        Stock of the Company enter into similar agreements.

        In order to enforce the foregoing covenant, the Company shall have the
     right to place restrictive legends on the certificates representing the
     shares subject to this Section and to impose stop transfer instructions
     with respect to the Registrable Securities and such other shares of stock
     of each Holder (and the shares or securities of every other person subject
     to the foregoing restriction) until the end of such period.

        2.10 Rule 144 Reporting. With a view to making available the benefits of
     certain rules and regulations of the Commission which may at any time
     permit the sale of the Registrable Securities to the public without
     registration, after such time as a public market exists for the Common
     Stock of the Company, the Company agrees to:

             (a) Make and keep public information available, as those terms are
        understood and defined in Rule 144 under the Securities Act, at all
        times after the effective date of the first registration under the
        Securities Act filed by the Company for an offering of its securities to
        the general public;

             (b) Use reasonable, diligent efforts to file with the Commission in
        a timely manner all reports and other documents required of the Company
        under the Securities Act and the 1934 Act (at any time after it has
        become subject to such reporting requirements); and

                                  CONFIDENTIAL                      Page 8 of 14

<PAGE>   9


             (c) So long as a Holder owns any Registrable Securities, to furnish
        to the Holder forthwith upon request a written statement by the Company
        as to its compliance with the reporting requirements of said Rule 144
        (at any time after ninety (90) days after the effective date of the
        first registration statement filed by the Company for an offering of its
        securities to the general public), and of the Securities Act and the
        1934 Act (at any time after it has become subject to the reporting
        requirements of the 1934 Act), a copy of the most recent annual or
        quarterly report of the Company, and such other reports and documents of
        the Company as a Holder may reasonably request in availing itself of any
        rule or regulation of the Commission allowing a Holder to sell any such
        securities without registration (at any time after the Company has
        become subject to the reporting requirements of the 1934 Act).

        2.11 Termination of the Company's Obligations. The Company shall have no
     obligations pursuant to Sections 2.2 through 2.4 with respect to any
     request or requests for registration made by any Holder on a date more than
     five (5) years after the closing date of the Company's initial public
     offering. Notwithstanding anything to the contrary contained in Section 2.2
     or 2.4, if any Holder is eligible to sell Registrable Securities pursuant
     Rule 144(k) or any successor provision under the Securities Act (an
     "Excluded Holder"), the Registrable Securities of such Excluded Holder
     shall be disregarded in determining the requisite percentage of Registrable
     Securities that are required to initiate a registration pursuant to Section
     2.2 or 2.4 (i.e., a registration under Section 2.2 must be initiated by
     persons holding at least two-thirds of the Registrable Securities held by
     all Holders who are not Excluded Holders and a registration under Section
     2.4 must be initiated by persons holding at least 25% of the Registrable
     Securities held by all Holders who are not Excluded Holders). After a
     registration has been requested pursuant to Section 2.2 or 2.4, as the case
     may be, by the requisite percentage of shares held by Holders who are not
     Excluded Holders, all Holders (including Excluded Holders) shall be
     entitled to include their Registrable Securities in such registration
     subject to the terms and conditions of this Agreement.

        2.12 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 Registrable Securities then
     outstanding, 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 2.2 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 his 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 2.2(a), or within one hundred
     twenty (120) days of the effective date of any registration effected
     pursuant to Section 2.2.

     3. PRE-EMPTIVE RIGHTS.

        3.1 General. Each Holder (as defined in Section 2.1(d)) and any party to
     whom such Holder's rights under this Section 3 have been duly assigned in
     accordance with Section 4.1(b) (each such Holder or assignee being
     hereinafter referred to as a "RIGHTS HOLDER") has the right of first
     refusal to purchase such Rights Holder's Pro Rata Share (as defined below),
     of all (or any part) of any "New Securities" (as defined in Section 3.2)
     that the Company may from time to time issue after the date of this
     Agreement. A Rights Holder's "PRO RATA SHARE" for purposes of this right of
     first refusal is the ratio of (a) the number of Registrable Securities as
     to which such Rights Holder is the Holder (and/or is deemed to be the
     Holder under Section 2.1(d)), to (b) a number of shares of Common Stock of
     the Company equal to the sum of (i) the total number of shares of Common
     Stock of the Company then outstanding plus (ii) the total number of shares
     of Common Stock of the Company into which all then outstanding shares of
     Preferred Stock of the Company are then convertible.

        3.2 New Securities. "NEW SECURITIES" shall mean any Common Stock or
     Preferred Stock of the Company, whether now authorized or not, and rights,
     options or warrants to purchase such Common Stock or Preferred Stock, and
     securities of any type whatsoever that are, or may become, convertible or
     exchangeable into such Common Stock or Preferred Stock; provided, however,
     that the term "New Securities" does not include:

             (a) up to 5,000,000 shares of the Company's Common Stock (and/or
        options or warrants therefor) issued to employees, officers, directors,
        contractors, advisors or consultants of the Company pursuant to
        incentive agreements or plans approved by the Board of Directors of the
        Company;

             (b) any shares of Series A Stock, Series B Preferred Stock or
        Series C Preferred Stock set forth in Exhibit A hereto (the "ISSUED
        PREFERRED STOCK");

             (c) any securities issuable upon conversion of or with respect to
        any then outstanding shares of Series A Stock, Series B Stock or Series
        C Stock of the Company or Common Stock or other securities issuable upon
        conversion thereof;

                                  CONFIDENTIAL                      Page 9 of 14

<PAGE>   10


             (d) any securities issuable upon exercise of any options, warrants
        or rights to purchase any securities of the Company outstanding on the
        date of this Agreement ("WARRANT SECURITIES") and any securities
        issuable upon the conversion of any Warrant Securities or upon the
        exercise or conversion of any securities, if such securities were first
        offered to the Rights Holders hereunder;

             (e) shares of the Company's Common Stock or Preferred Stock issued
        in connection with any stock split or stock dividend;

             (f) securities offered by the Company to the public pursuant to a
        registration statement filed under the Securities Act;

             (g) up to 125,000 shares of the Company's Common Stock or Preferred
        Stock (and/or options or warrants therefor) issued or issuable to
        parties providing the Company with equipment leases, real property
        leases, loans, credit lines, guaranties of indebtedness, cash price
        reductions or similar financing such number of shares being subject to
        proportional adjustment to reflect subdivisions, combinations and stock
        dividends affecting the number of outstanding shares of such stock; or

             (h) securities issued pursuant to the acquisition of another
        corporation or entity by the Company by consolidation, merger, purchase
        of all or substantially all of the assets, or other reorganization in
        which the Company acquires, in a single transaction or series of related
        transactions, all or substantially all of the assets of such other
        corporation or entity or fifty percent (50%) or more of the voting power
        of such other corporation or entity or fifty percent (50%) or more of
        the equity ownership of such other entity.

        3.3 Procedures. In the event that the Company proposes to undertake an
     issuance of New Securities, it shall give to each Rights Holder written
     notice of its intention to issue New Securities (the "NOTICE"), describing
     the type of New Securities and the price and the general terms upon which
     the Company proposes to issue such New Securities. Each Rights Holder shall
     have ten (10) days from the date of mailing of any such Notice to agree in
     writing to purchase such Rights Holder's Pro Rata Share of such New
     Securities for the price and upon the general terms specified in the Notice
     by giving written notice to the Company and stating therein the quantity of
     New Securities to be purchased (not to exceed such Rights Holder's Pro Rata
     Share). If any Rights Holder fails to so agree in writing within such ten
     (10) day period to purchase such Rights Holder's full Pro Rata Share of an
     offering of New Securities (a "NONPURCHASING HOLDER"), then such
     Nonpurchasing Holder shall forfeit the right hereunder to purchase that
     part of his Pro Rata Share of such New Securities that he did not so agree
     to purchase and the Company shall promptly give each Rights Holder who has
     timely agreed to purchase his full Pro Rata Share of such offering of New
     Securities (a "PURCHASING HOLDER") written notice of the failure of any
     Nonpurchasing Holder to purchase such Nonpurchasing Rights Holder's full
     Pro Rata Share of such offering of New Securities (the "OVERALLOTMENT
     NOTICE"). Each Purchasing Holder shall have a right of overallotment such
     that such Purchasing Holder may agree to purchase a portion of the
     Nonpurchasing Holders' unpurchased Pro Rata Shares of such offering on a
     pro rata basis according to the relative Pro Rata Shares of the Purchasing
     Rights Holders, at any time within five (5) days after receiving the
     Overallotment Notice.

        3.4 Failure to Exercise. In the event that the Rights Holders fail to
     exercise in full the right of first refusal within such ten (10) plus five
     (5) day period, then the Company shall have 120 days thereafter to sell the
     New Securities with respect to which the Rights Holders' rights of first
     refusal hereunder were not exercised, at a price and upon general terms not
     materially more favorable to the purchasers thereof than specified in the
     Company's Notice to the Rights Holders. In the event that the Company has
     not issued and sold the New Securities within such 120-day period, then the
     Company shall not thereafter issue or sell any New Securities without again
     first offering such New Securities to the Rights Holders pursuant to this
     Section 3.

        3.5 Termination. This right of first refusal shall terminate (a)
     immediately before the closing of the first underwritten sale of Common
     Stock of the Company to the public pursuant to a registration statement
     filed with, and declared effective by, the SEC under the Securities Act,
     covering the offer and sale of Common Stock to the public at an offering
     price of at least $2.20 per share (such offering price being subject to
     proportional adjustment to reflect subdivisions, combinations, stock
     dividends and similar transactions affecting the number of outstanding
     shares of Common Stock) for an aggregate gross public offering price
     (calculated before deduction of underwriters' discounts and commissions) of
     at least $15,000,000 or (b) upon (i) the acquisition of all or
     substantially all the assets of the Company or (ii) an acquisition of the
     Company by another corporation or

                                  CONFIDENTIAL                     Page 10 of 14

<PAGE>   11


     entity by consolidation, merger or other reorganization in which the
     holders of the Company's outstanding voting stock immediately prior to such
     transaction own, immediately after such transaction, securities
     representing less than fifty percent (50%) or more of the voting power of
     the corporation or other entity surviving such transaction.

        3.6 Waiver. Each Rights Holder hereby confirms its waiver of any right
     of first refusal it may have had to purchase such Rights Holder's Pro Rata
     Share of the Issued Preferred Stock.

     4. ASSIGNMENT AND AMENDMENT.

        4.1 Assignment. Notwithstanding anything herein to the contrary:

             (a) Information Rights. The rights of an Investor under Section 1.1
        or 1.2 or 1.4 hereof may be assigned only to (i) a party who acquires
        from an Investor (or an Investor's permitted assigns) at least 500,000
        shares of Series A Stock, Series B Stock or Series C Stock subject to
        this Agreement and/or 250,000 shares (on an as-converted basis) of
        Registrable Securities issued upon conversion thereof or (ii) a partner,
        member or stockholder of an Investor who acquires at least 100,000
        shares of Series A Stock, Series B Stock, or Series C Stock subject to
        this Agreement and/or 50,000 shares (on an as-converted basis) of
        Registrable Securities issued upon conversion.

             (b) Registration Rights; Refusal Rights. The registration rights of
        a Holder under Section 2 hereof and the rights of first refusal of a
        Rights Holder under Section 3 hereof may be assigned only to (i) a party
        who acquires at least 500,000 shares of Series A Stock, Series B Stock
        or Series C Stock subject to this Agreement and/or 250,000 shares (on an
        as-converted basis) of Registrable Securities issued upon conversion
        thereof or (ii) any partner, member or shareholder of an Investor or
        permitted transferee thereof; provided, however that no party may be
        assigned any of the foregoing rights unless the Company is given written
        notice by the assigning party at the time of such assignment stating the
        name and address of the assignee and identifying the securities of the
        Company as to which the rights in question are being assigned; and
        provided further that any such assignee shall receive such assigned
        rights subject to all the terms and conditions of this Agreement,
        including without limitation the provisions of this Section 4.

        4.2 Amendment of Rights. Any provision of this Agreement may be amended
     and the observance thereof may be waived (either generally or in a
     particular instance and either retroactively or prospectively), only with
     the written consent of the Company and Investors (and/or any of their
     permitted successors or assigns) holding shares of Series A Stock, Series B
     Stock, Series C Stock and/or Conversion Stock representing and/or
     convertible into a majority of all the Investors' Shares (as defined
     below). As used herein, the term "INVESTORS' SHARES" shall mean the shares
     of Common Stock then issuable upon conversion of all then outstanding
     shares of Series A Stock, Series B Stock and Series C Stock subject to this
     Agreement plus all then outstanding shares of Conversion Stock that were
     issued upon the conversion of any shares of Series A Stock, Series B Stock
     or Series C Stock subject to this Agreement. Any amendment or waiver
     effected in accordance with this Section 4.2 shall be binding upon each
     Investor, each Holder, each permitted successor or assignee of such
     Investor or Holder and the Company.

     5. GENERAL PROVISIONS.

        5.1 Notices. Any notice, request or other communication required or
     permitted hereunder shall be in writing and shall be deemed to have been
     duly given if personally delivered or if deposited in the U.S. mail by

                  financial position and consolidated financial results of the
                  Company for the fiscal quarter covered.

                           Each Investor agrees to hold all information received
         pursuant to this Section in confidence, and not to use or disclose any
         of such information to any third party, except to the extent such

                  issued as) a dividend or other distribution with respect to,
                  or in exchange for or in replacement of, all such shares of
                  Common Stock described in clause (i) of this subsection (b);
                  excluding in all cases, however, any Registrable Securities
                  sold by a person in a transaction in which rights under this
                  Section 2 are not assigned in accordance with this Agreement
                  or any Registrable Securities sold to the public or sold
                  pursuant to Rule 144 promulgated under the Securities Act.

                           (c) Registrable Securities Then Outstanding. The
                  number of shares of "REGISTRABLE SECURITIES THEN OUTSTANDING"
                  shall mean the number of shares of Common Stock which are
                  Registrable Securities and (i) are then issued and outstanding
                  or (ii) are then issuable pursuant to the exercise or
                  conversion of then outstanding and then exercisable options,
                  warrants or convertible securities.

                           (d) Holder. For purposes of this Section 2 and

                  sold to the public or pursuant to Rule 144 promulgated under
                  the Securities Act or any assignee of record of such
                  Registrable Securities to whom rights under such Sections have
                  been duly assigned in accordance with this Agreement;
                  provided, however, that for purposes of this Agreement, a
                  record holder of the Warrant or shares of Series A Stock,
                  Series B Stock or Series C Stock convertible into such
                  Registrable Securities shall be deemed to be the Holder of
                  such Registrable Securities; and provided, further, that the
                  Company shall in no event be obligated to register the Warrant
                  or shares of Series A Stock, Series B Stock, or Series C Stock
                  and that Holders of Registrable Securities will not be
                  required to convert the Warrant or their shares of Series A
                  Stock, Series B Stock or Series C Stock into Common Stock in
                  order to exercise the registration rights granted hereunder,
                  until immediately before the closing of the offering to which
                  the registration relates.

                           (e) Form S-3. The term "FORM S-3" means such form
                  under the Securities Act as is in effect on the date hereof or
                  any successor registration form under the Securities Act
                  subsequently adopted by the SEC which permits inclusion or
                  incorporation of substantial information by reference to other
                  documents filed by the Company with the SEC.

                           (f) SEC. The term "SEC" or "COMMISSION" means the
                  U.S. Securities and Exchange Commission.

                           (g) Series A Stock. The term "SERIES A STOCK" shall

                  per share.

                           (h) Series B Stock. The term "SERIES B STOCK" shall

                  per share.

                           (i) Series C Stock. The term "SERIES C STOCK" shall

                  per share.

                  2.2      Demand Registration.

                           (a) Request by Holders. If the Company shall receive
                  at any time after six (6) months after the effective date of
                  the Company's initial public offering of its securities
                  pursuant to a registration filed under the Securities Act, a
                  written request from the Holders of at least two-thirds of the
                  Registrable Securities then outstanding that the Company file
                  a registration statement under the Securities Act covering the
                  registration of Registrable Securities pursuant to this
                  Section 2.2, then the Company shall, within twenty (20) days
                  after the receipt of such written request, give written notice
                  of

                                  CONFIDENTIAL                      Page 2 of 14
<PAGE>   3


                  such request ("REQUEST NOTICE") to all Holders, and effect, as
                  soon as practicable, the registration under the Securities Act
                  of all Registrable Securities which Holders request to be
                  registered and included in such registration by written notice
                  given by such Holders to the Company within twenty (20) days
                  after receipt of the Request Notice, subject only to the
                  limitations of this Section 2; provided that the Registrable
                  Securities requested by all Holders to be registered pursuant
                  to such request must be at least twenty-five percent (25%) of
                  all Registrable Securities then outstanding.

                           (b) Underwriting. If the Holders initiating the
                  registration request under this Section 2.2 ("INITIATING
                  HOLDERS") intend to distribute the Registrable Securities
                  covered by their request by means of an underwriting, then
                  they shall so advise the Company as a part of their request
                  made pursuant to this Section 2.2 and the Company shall
                  include such information in the written notice referred to in
                  subsection 2.2(a). In such event, the right of any Holder to
                  include his 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 enter into an underwriting agreement in
                  customary form with the managing underwriter or underwriters
                  selected for such underwriting by the Company. Notwithstanding
                  any other provision of this Section 2.2, if the underwriter(s)
                  advise(s) the Company in writing that marketing factors
                  require a limitation of the number of securities to be
                  underwritten then the Company shall so advise all Holders of
                  Registrable Securities that would otherwise be registered and
                  underwritten pursuant hereto, and the number of Registrable
                  Securities that may be included in the underwriting shall be
                  reduced as required by the underwriter(s) and allocated among
                  the Holders of Registrable Securities on a pro rata basis
                  according to the number of Registrable Securities then
                  outstanding held by each Holder requesting registration
                  (including the Initiating Holders); provided, however, that
                  the number of shares of Registrable Securities to be included
                  in such underwriting and registration shall not be reduced
                  unless all other securities of the Company are first entirely
                  excluded from the underwriting and registration. Any
                  Registrable Securities excluded and withdrawn from such
                  underwriting shall be withdrawn from the registration.

                           (c) Maximum Number of Demand Registrations. The
                  Company is obligated to effect only two (2) such registrations
                  pursuant to this Section 2.2.

                           (d) Deferral. Notwithstanding the foregoing, if the
                  Company shall furnish to Holders requesting the filing of a
                  registration statement pursuant to this Section 2.2, a
                  certificate signed by the President or Chief Executive Officer
                  of the Company stating that in the good faith judgment of the
                  Board of Directors of the Company, it would be seriously
                  detrimental to the Company and its stockholders for such
                  registration statement to be filed and it is therefore
                  essential to defer the filing of such registration statement,
                  then the Company shall have the right to defer such filing for
                  a period of not more than one hundred twenty (120) 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 (12) month period.

                           (e) Expenses. All expenses incurred in connection
                  with a registration pursuant to this Section 2.2, including
                  without limitation all registration and qualification fees,
                  printers' and accounting fees, fees and disbursements of
                  counsel for the Company, and the reasonable fees and
                  disbursements of one counsel for the selling Holders (but
                  excluding underwriters' discounts and commissions), shall be
                  borne by the Company. Each Holder participating in a
                  registration pursuant to this Section 2.2 shall bear such
                  Holder's proportionate share (based on the total number of
                  shares sold in such registration other than for the account of
                  the Company) of all discounts, commissions or other amounts
                  payable to underwriters or brokers in connection with such
                  offering. Notwithstanding the foregoing, the Company shall not
                  be required to pay for any expenses of any registration
                  proceeding begun pursuant to this Section 2.2 if the
                  registration request is subsequently withdrawn at the request
                  of the Holders of a majority of the Registrable Securities to
                  be registered, unless the Holders of a majority of the
                  Registrable Securities then outstanding agree to forfeit their
                  right to one (1) demand registration pursuant to this Section
                  2.2 (in which case such right shall be forfeited by all
                  Holders of Registrable Securities); provided, further,
                  however, that if at the time of such withdrawal, the Holders
                  have learned of a material adverse change in the condition,
                  business, or prospects of the Company not known to the Holders
                  at the time of their request for such registration and have
                  withdrawn their request for registration with reasonable
                  promptness after learning of such material adverse change,
                  then the Holders shall not be required to pay any of such
                  expenses and shall retain their rights pursuant to this
                  Section 2.2.

                  2.3 Piggyback Registrations. The Company shall notify all
         Holders of Registrable Securities in writing at least thirty (30) days
         prior to filing any registration statement under the Securities Act for
         purposes of effecting a public offering of securities of the Company
         (including, but not limited to, registration statements relating to
         secondary offerings of securities of the Company, but excluding
         registration statements relating to any registration under Section 2.2
         or Section 2.4 of this Agreement or to any employee benefit plan or a
         corporate reorganization) and will afford each such Holder an
         opportunity to include in such registration statement all or any part
         of the Registrable Securities then held by such Holder. Each Holder
         desiring to include in any such registration statement all or any part
         of the Registrable Securities held by such Holder shall, within twenty
         (20) days after receipt of the above-described notice from the Company,
         so notify the Company in writing, and in such notice shall inform the
         Company of the number of Registrable Securities such Holder wishes to
         include in such registration statement. If a Holder decides not to
         include all of its Registrable Securities in any registration statement
         thereafter filed by the Company, such Holder shall nevertheless
         continue to have the right to include any Registrable Securities in any
         subsequent registration statement or registration statements as may be
         filed by the Company with respect to offerings of its securities, all
         upon the terms and conditions set forth herein.

                           (a) Underwriting. If a registration statement under
                  which the Company gives notice under this Section 2.3 is for
                  an underwritten offering, then the Company shall so advise the
                  Holders of Registrable Securities. In such event, the right of
                  any such Holder's Registrable Securities to be included in a
                  registration pursuant to this Section 2.3 shall be conditioned
                  upon such Holder's participation in such underwriting and the
                  inclusion of such Holder's Registrable Securities in the
                  underwriting to the extent provided herein. All Holders
                  proposing to distribute their Registrable Securities through
                  such underwriting shall enter into an underwriting agreement
                  in customary form with the managing underwriter or
                  underwriter(s) selected for such underwriting. Notwithstanding
                  any other provision of this Agreement, if the managing
                  underwriter determine(s) in good faith that marketing factors
                  require a limitation of the number of shares to be
                  underwritten, then the managing underwriter(s) may exclude
                  shares (including Registrable Securities) from the
                  registration and the underwriting, and the number of shares
                  that may be included in the registration and the underwriting
                  shall be allocated, first, to stockholders exercising any
                  demand registration rights, second to the Company, and third,
                  to each of the Holders requesting inclusion of their
                  Registrable Securities in such registration statement on a pro
                  rata basis based on the total number of Registrable Securities
                  then held by each such Holder; provided however, that the
                  right of the underwriters to exclude shares (including
                  Registrable Securities) from the registration and underwriting
                  as described above shall be restricted so that: (i) the number
                  of Registrable Securities included in any such registration is
                  not reduced below twenty-five percent (25%) of the shares
                  included in the registration, except for a registration
                  relating to the Company's initial public offering or an
                  offering solely by stockholders of the Company exercising
                  demand registration rights, from which all Registrable
                  Securities may be excluded, and (ii) all shares that are not
                  Registrable Securities and are held by persons who are
                  employees or directors of the Company (or any subsidiary of
                  the Company) shall first be excluded from such registration
                  and underwriting before any Registrable Securities are so
                  excluded. If any Holder disapproves of the terms of any such
                  underwriting, such Holder may elect to withdraw therefrom by
                  written notice to the Company and the underwriter, delivered
                  at least twenty (20) days prior to the effective date of the
                  registration statement. Any Registrable Securities excluded or
                  withdrawn from such underwriting shall be excluded and
                  withdrawn from the registration. For any Holder that is a
                  partnership or corporation, the partners, retired partners and
                  stockholders 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 "Holder," and any pro rata reduction with respect
                  to such "Holder" shall be based upon the aggregate amount of
                  shares carrying registration rights owned by all entities and
                  individuals included in such "Holder," as defined in this
                  sentence.

                           (b) Expenses. All expenses incurred in connection
                  with a registration pursuant to this Section 2.3 (excluding
                  underwriters' and brokers' discounts and commissions),
                  including, without limitation all federal and "blue sky"
                  registration and qualification fees, printers' and accounting
                  fees, fees and disbursements of counsel for the Company and
                  reasonable fees and disbursements of one counsel for the
                  selling Holders shall be borne by the Company.

                  2.4 Form S-3 Registration. In case the Company shall receive
         from any Holder or Holders of at least twenty-five percent (25%) of all
         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, then the
         Company will:

<PAGE>   5


                           (a) Notice. Promptly give written notice of the
                  proposed registration and the Holder's or Holders' request
                  therefor, and any related qualification or compliance, to all
                  other Holders of Registrable Securities; and

                           (b) Registration. As soon as practicable, effect 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
                  twenty (20) 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 2.4:

                                    (i) if Form S-3 is not available for such
                           offering;

                                    (ii) if the Holders, together with the
                           holders of any other securities of the Company
                           entitled to inclusion in such registration, propose
                           to sell Registrable Securities and such other
                           securities (if any) at an aggregate price to the
                           public of less than $1,000,000;

                                    (iii) if the Company shall furnish to the
                           Holders a certificate signed by the President or
                           Chief Executive Officer of the Company stating that
                           in the good faith judgment of the Board of Directors
                           of the Company, it would be seriously detrimental to
                           the Company and its stockholders for such Form S-3
                           Registration to be effected at such time, in which
                           event the Company shall have the right to defer the
                           filing of the Form S-3 registration statement no more
                           than once during any twelve month period for a period
                           of not more than 120 days after receipt of the
                           request of the Holder or Holders under this Section
                           2.4;

                                    (iv) if the Company has, within the twelve
                           (12) month period preceding the date of such request,
                           already effected two (2) registrations on Form S-3
                           for the Holders pursuant to this Section 2.4; or

                                    (v) 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) Expenses. Subject to the foregoing, the Company
                  shall file a Form S-3 registration statement covering the
                  Registrable Securities and other securities so requested to be
                  registered pursuant to this Section 2.4 as soon as practicable
                  after receipt of the request or requests of the Holders for
                  such registration. The Company shall pay all expenses incurred
                  in connection with each registration requested pursuant to
                  this Section 2.4, (excluding underwriters' or brokers'
                  discounts and commissions), including without limitation all
                  filing, registration and qualification, printers' and
                  accounting fees and the reasonable fees and disbursements of
                  one counsel for the selling Holder or Holders and counsel for
                  the Company.

                           (d) Not Demand Registration. Form S-3 registrations
                  shall not be deemed to be demand registrations as described in
                  Section 2.2 above.

                  2.5 Obligations of the Company. Whenever required to effect
         the registration of any Registrable Securities under this Agreement,
         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
                  reasonable, diligent 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, keep such registration statement effective for up
                  to ninety (90) days.

                           (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 Securities Act
                  with respect to the disposition of all securities covered by
                  such registration statement.

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

                           (d) Use reasonable, diligent 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


                                  CONFIDENTIAL                      Page 5 of 14

                  therewith or as a condition thereto to qualify to do business
                  or to file a general consent to service of process in any such
                  states or jurisdictions.

                           (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(s) 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 Securities 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.

                           (g) Furnish, at the request of any Holder requesting
                  registration of Registrable Securities, on the date that such
                  Registrable Securities are delivered to the underwriters for
                  sale, 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 as of 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 and reasonably satisfactory to a majority in
                  interest of the Holders requesting registration, addressed to
                  the underwriters, if any, and to the Holders requesting
                  registration of Registrable Securities and (ii) a "comfort"
                  letter dated as of 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 and
                  reasonably satisfactory to a majority in interest of the
                  Holders requesting registration, addressed to the
                  underwriters, if any, and to the Holders requesting
                  registration of Registrable Securities.

                  2.6 Furnish Information. It shall be a condition precedent to
         the obligations of the Company to take any action pursuant to Sections
         2.2, 2.3 or 2.4 that the selling Holders shall furnish to the Company
         such information regarding themselves, the Registrable Securities held
         by them, and the intended method of disposition of such securities as
         shall be required to timely effect the registration of their
         Registrable Securities.

                  2.7 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 2.

                  2.8 Indemnification. In the event any Registrable Securities
         are included in a registration statement under Sections 2.2, 2.3 or
         2.4:

                           (a) By the Company. To the extent permitted by law,
                  the Company will indemnify and hold harmless each Holder, the
                  partners, officers and directors of each Holder, any
                  underwriter (as defined in the Securities Act) for such Holder
                  and each person, if any, who controls such Holder or
                  underwriter within the meaning of the Securities Act or the
                  Securities Exchange Act of 1934, as amended, (the "1934 ACT"),
                  against any losses, claims, damages, or liabilities (joint or
                  several) to which they may become subject under the Securities
                  Act, the l934 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,
                  "VIOLATIONS" and, individually, 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 Securities Act, the 1934 Act, any
                           federal or state securities law or any rule or
                           regulation promulgated under the Securities Act, the
                           1934 Act or any federal or state securities law in
                           connection with the offering covered by such
                           registration statement; and the Company will
                           reimburse each such Holder, partner, officer or
                           director, underwriter or controlling person for any
                           legal or other expenses reasonably incurred by them,
                           as incurred, in connection with investigating or
                           defending any such loss, claim, damage, liability or
                           action; provided however, that the indemnity
                           agreement contained in this subsection 2.8(a) shall
                           not apply to amounts paid in


                                  CONFIDENTIAL                      Page 6 of 14

<PAGE>   7


                           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), nor shall the Company be
                           liable 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 such Holder,
                           partner, officer, director, underwriter or
                           controlling person of such Holder.

                           (b) By Selling Holders. To the extent permitted by
                  law, each selling Holder will indemnify and hold harmless the
                  Company, each of its directors, each of its officers who have
                  signed the registration statement, each person, if any, who
                  controls the Company within the meaning of the Securities Act,
                  any underwriter and any other Holder selling securities under
                  such registration statement or any of such other Holder's
                  partners, directors or officers or any person who controls
                  such Holder within the meaning of the Securities Act or the
                  1934 Act, against any losses, claims, damages or liabilities
                  (joint or several) to which the Company or any such director,
                  officer, controlling person, underwriter or other such Holder,
                  partner or director, officer or controlling person of such
                  other Holder may become subject under the Securities 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 reimburse any legal or other expenses reasonably incurred
                  by the Company or any such director, officer, controlling
                  person, underwriter or other Holder, partner, officer,
                  director or controlling person of such other Holder in
                  connection with investigating or defending any such loss,
                  claim, damage, liability or action; provided, however, that
                  the indemnity agreement contained in this subsection 2.8(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, that
                  the total amounts payable in indemnity by a Holder under this
                  Section 2.8(b) in respect of any Violation shall not exceed
                  the net proceeds received by such Holder in the registered
                  offering out of which such Violation arises.

                           (c) Notice. Promptly after receipt by an indemnified
                  party under this Section 2.8 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 2.8,
                  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; provided, however, that
                  an indemnified party shall have the right to retain its own
                  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 conflict of
                  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 2.8, 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 2.8.

                           (d) Defect Eliminated in Final Prospectus. The
                  foregoing indemnity agreements of the Company and Holders are
                  subject to the condition that, insofar as they relate to any
                  Violation made in a preliminary prospectus but eliminated or
                  remedied in the amended prospectus on file with the SEC at the
                  time the registration statement in question becomes effective
                  or the amended prospectus filed with the SEC pursuant to SEC
                  Rule 424(b) (the "FINAL PROSPECTUS"), such indemnity agreement
                  shall not inure to the benefit of any person if a copy of the
                  Final Prospectus was furnished to the indemnified party and
                  was not furnished to the person asserting the loss, liability,
                  claim or damage at or prior to the time such action is
                  required by the Securities Act.

                           (e) Contribution. In order to provide for just and
                  equitable contribution to joint liability under the Securities
                  Act in any case in which either (i) any Holder exercising
                  rights under this Agreement, or any controlling person of any
                  such Holder, makes a claim for indemnification pursuant to
                  this Section 2.8 but it is judicially determined (by the entry
                  of a final judgment or decree by a court of competent
                  jurisdiction and the expiration of time to appeal or the
                  denial of the last right of appeal) that such indemnification
                  may not be enforced in such case notwithstanding the fact that
                  this Section 2.8 provides for indemnification in such case, or
                  (ii) contribution under the Securities Act may be required

                  on the part of any such selling Holder or any such controlling
                  person in circumstances for which indemnification is provided
                  under this Section 2.8; then, and in each such case, the
                  Company and such Holder will contribute to the aggregate
                  losses, claims, damages or liabilities to which they may be
                  subject (after contribution from others) in such proportion so
                  that such Holder is responsible for the portion represented by
                  the percentage that the public offering price of its
                  Registrable Securities offered by and sold under the
                  registration statement bears to the public offering price of
                  all securities offered by and sold under such registration
                  statement, and the Company and other selling Holders are
                  responsible for the remaining portion; provided, however,
                  that, in any such case, (A) no such Holder will be required to
                  contribute any amount in excess of the public offering price
                  of all such Registrable Securities offered and sold by such
                  Holder pursuant to such registration statement; and (B) no
                  person or entity guilty of fraudulent misrepresentation
                  (within the meaning of Section 11(f) of the Securities Act)
                  will be entitled to contribution from any person or entity who
                  was not guilty of such fraudulent misrepresentation.

                           (f) Survival. The obligations of the Company and
                  Holders under this Section 2.8 shall survive the completion of
                  any offering of Registrable Securities in a registration
                  statement, and otherwise.

                  2.9 "Market Stand-Off" Agreement. Each Holder hereby agrees
         that it shall not, to the extent requested by the Company or an
         underwriter of securities of the Company, sell or otherwise transfer or
         dispose of any Registrable Securities or other shares of stock of the
         Company then owned by such Holder (other than to donees or partners of
         the Holder who agree to be similarly bound) for up to one hundred
         eighty (180) days following the effective date of a registration
         statement of the Company filed under the Securities Act; provided,
         however, that:

                           (a) such agreement shall be applicable only to the
                  first such registration statement of the Company which covers
                  securities to be sold on its behalf to the public in an
                  underwritten offering but not to Registrable Securities sold
                  pursuant to such registration statement; and

                           (b) all officers and directors of the Company then
                  holding Common Stock of the Company enter into similar
                  agreements.

                  In order to enforce the foregoing covenant, the Company shall
         have the right to place restrictive legends on the certificates
         representing the shares subject to this Section and to impose stop
         transfer instructions with respect to the Registrable Securities and
         such other shares of stock of each Holder (and the shares or securities
         of every other person subject to the foregoing restriction) until the
         end of such period.

                  2.10 Rule 144 Reporting. With a view to making available the
         benefits of certain rules and regulations of the Commission which may
         at any time permit the sale of the Registrable Securities to the public
         without registration, after such time as a public market exists for the
         Common Stock of the Company, the Company agrees to:

                           (a) Make and keep public information available, as
                  those terms are understood and defined in Rule 144 under the
                  Securities Act, at all times after the effective date of the
                  first registration under the Securities Act filed by the
                  Company for an offering of its securities to the general
                  public;

                           (b) Use reasonable, diligent efforts to file with the
                  Commission in a timely manner all reports and other documents
                  required of the Company under the Securities Act and the 1934
                  Act (at any time after it has become subject to such reporting
                  requirements); and

                           (c) So long as a Holder owns any Registrable
                  Securities, to furnish to the Holder forthwith upon request a
                  written statement by the Company as to its compliance with the
                  reporting requirements of said Rule 144 (at any time after
                  ninety (90) days after the effective date of the first
                  registration statement filed by the Company for an offering of
                  its securities to the general public), and of the Securities
                  Act and the 1934 Act (at any time after it has become subject
                  to the reporting requirements of the 1934 Act), a copy of the
                  most recent annual or quarterly report of the Company, and
                  such other reports and documents of the Company as a Holder
                  may reasonably request in availing itself of any rule or
                  regulation of the Commission allowing a Holder to sell any
                  such securities without registration (at any time after the
                  Company has become subject to the reporting requirements of
                  the 1934 Act).

                  2.11 Termination of the Company's Obligations. The Company
         shall have no obligations pursuant to Sections 2.2 through 2.4 with
         respect to any request or requests for registration made by any Holder
         on a date more than five (5) years after the closing date of the
         Company's initial public offering. Notwithstanding anything to the
         contrary contained in Section 2.2 or 2.4, if any Holder is eligible to
         sell Registrable Securities pursuant Rule 144(k) or any successor
         provision under the Securities Act (an "Excluded Holder"), the


                                  CONFIDENTIAL                      Page 8 of 14
<PAGE>   9


         Registrable Securities of such Excluded Holder shall be disregarded in
         determining the requisite percentage of Registrable Securities that are
         required to initiate a registration pursuant to Section 2.2 or 2.4
         (i.e., a registration under Section 2.2 must be initiated by persons
         holding at least two-thirds of the Registrable Securities held by all
         Holders who are not Excluded Holders and a registration under Section
         2.4 must be initiated by persons holding at least 25% of the
         Registrable Securities held by all Holders who are not Excluded
         Holders). After a registration has been requested pursuant to Section
         2.2 or 2.4, as the case may be, by the requisite percentage of shares
         held by Holders who are not Excluded Holders, all Holders (including
         Excluded Holders) shall be entitled to include their Registrable
         Securities in such registration subject to the terms and conditions of
         this Agreement.

                  2.12 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 Registrable
         Securities then outstanding, 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 2.2 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 his 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 2.2(a), or within one hundred twenty (120) days
         of the effective date of any registration effected pursuant to Section
         2.2.

         3.       PRE-EMPTIVE RIGHTS.

                  3.1 General. Each Holder (as defined in Section 2.1(d)) and
         any party to whom such Holder's rights under this Section 3 have been
         duly assigned in accordance with Section 4.1(b) (each such Holder or
         assignee being hereinafter referred to as a "RIGHTS HOLDER") has the
         right of first refusal to purchase such Rights Holder's Pro Rata Share
         (as defined below), of all (or any part) of any "New Securities" (as
         defined in Section 3.2) that the Company may from time to time issue
         after the date of this Agreement. A Rights Holder's "PRO RATA SHARE"
         for purposes of this right of first refusal is the ratio of (a) the
         number of Registrable Securities as to which such Rights Holder is the
         Holder (and/or is deemed to be the Holder under Section 2.1(d)), to (b)
         a number of shares of Common Stock of the Company equal to the sum of
         (i) the total number of shares of Common Stock of the Company then
         outstanding plus (ii) the total number of shares of Common Stock of the
         Company into which all then outstanding shares of Preferred Stock of
         the Company are then convertible.

                  3.2 New Securities. "NEW SECURITIES" shall mean any Common
         Stock or Preferred Stock of the Company, whether now authorized or not,
         and rights, options or warrants to purchase such Common Stock or
         Preferred Stock, and securities of any type whatsoever that are, or may
         become, convertible or exchangeable into such Common Stock or Preferred
         Stock; provided, however, that the term "New Securities" does not
         include:

                      (a) up to 8,000,000 shares of the Company's Common Stock
                  (and/or options or warrants therefor) issued to employees,
                  officers, directors, contractors, advisors or consultants of
                  the Company pursuant to incentive agreements or plans approved
                  by the Board of Directors of the Company;

                      (b) any shares of Series A Stock, Series B Preferred Stock
                  or Series C Preferred Stock set forth in Exhibit A hereto (the
                  "ISSUED PREFERRED STOCK");

                      (c) any securities issuable upon conversion of or with
                  respect to any then outstanding shares of Series A Stock,
                  Series B Stock or Series C Stock of the Company or Common
                  Stock or other securities issuable upon conversion thereof;

                      (d) any securities issuable upon exercise of any options,
                  warrants or rights to purchase any securities of the Company
                  outstanding on the date of this Agreement ("WARRANT
                  SECURITIES") and any securities issuable upon the conversion
                  of any Warrant Securities or upon the exercise or conversion
                  of any securities, if such securities were first offered to
                  the Rights Holders hereunder;

                      (e) shares of the Company's Common Stock or Preferred
                  Stock issued in connection with any stock split or stock
                  dividend;

                      (f) securities offered by the Company to the public
                  pursuant to a registration statement filed under the
                  Securities Act;

                      (g) up to 125,000 shares of the Company's Common Stock or
                  Preferred Stock (and/or options or warrants therefor) issued
                  or issuable to parties providing the Company with equipment
                  leases, real property leases, loans, credit lines, guaranties
                  of indebtedness, cash price reductions or similar financing
                  such number of shares being subject to proportional adjustment
                  to reflect


                                  CONFIDENTIAL                      Page 9 of 14
<PAGE>   10


                  subdivisions, combinations and stock dividends affecting the
                  number of outstanding shares of such stock;

                      (h) securities issued pursuant to the acquisition of
                  another corporation or entity by the Company by consolidation,
                  merger, purchase of all or substantially all of the assets, or
                  other reorganization in which the Company acquires, in a
                  single transaction or series of related transactions, all or
                  substantially all of the assets of such other corporation or
                  entity or fifty percent (50%) or more of the voting power of
                  such other corporation or entity or fifty percent (50%) or
                  more of the equity ownership of such other entity; or

                      (i) up to 3,000,000 shares of the Company's Common Stock
                  (and/or options or warrants therefor) issued or issuable in
                  connection with strategic alliances or partnering arrangements
                  approved by the Board of Directors of the Company.

                  3.3 Procedures. In the event that the Company proposes to
         undertake an issuance of New Securities, it shall give to each Rights
         Holder written notice of its intention to issue New Securities (the
         "NOTICE"), describing the type of New Securities and the price and the
         general terms upon which the Company proposes to issue such New
         Securities. Each Rights Holder shall have ten (10) days from the date
         of mailing of any such Notice to agree in writing to purchase such
         Rights Holder's Pro Rata Share of such New Securities for the price and
         upon the general terms specified in the Notice by giving written notice
         to the Company and stating therein the quantity of New Securities to be
         purchased (not to exceed such Rights Holder's Pro Rata Share). If any
         Rights Holder fails to so agree in writing within such ten (10) day
         period to purchase such Rights Holder's full Pro Rata Share of an
         offering of New Securities (a "NONPURCHASING HOLDER"), then such
         Nonpurchasing Holder shall forfeit the right hereunder to purchase that
         part of his Pro Rata Share of such New Securities that he did not so
         agree to purchase and the Company shall promptly give each Rights
         Holder who has timely agreed to purchase his full Pro Rata Share of
         such offering of New Securities (a "PURCHASING HOLDER") written notice
         of the failure of any Nonpurchasing Holder to purchase such
         Nonpurchasing Rights Holder's full Pro Rata Share of such offering of
         New Securities (the "OVERALLOTMENT NOTICE"). Each Purchasing Holder
         shall have a right of overallotment such that such Purchasing Holder
         may agree to purchase a portion of the Nonpurchasing Holders'
         unpurchased Pro Rata Shares of such offering on a pro rata basis
         according to the relative Pro Rata Shares of the Purchasing Rights
         Holders, at any time within five (5) days after receiving the
         Overallotment Notice.

                  3.4 Failure to Exercise. In the event that the Rights Holders
         fail to exercise in full the right of first refusal within such ten
         (10) plus five (5) day period, then the Company shall have 120 days
         thereafter to sell the New Securities with respect to which the Rights
         Holders' rights of first refusal hereunder were not exercised, at a
         price and upon general terms not materially more favorable to the
         purchasers thereof than specified in the Company's Notice to the Rights
         Holders. In the event that the Company has not issued and sold the New
         Securities within such 120-day period, then the Company shall not
         thereafter issue or sell any New Securities without again first
         offering such New Securities to the Rights Holders pursuant to this
         Section 3.

                  3.5 Termination. This right of first refusal shall terminate
         (a) immediately before the closing of the first underwritten sale of
         Common Stock of the Company to the public pursuant to a registration
         statement filed with, and declared effective by, the SEC under the
         Securities Act, covering the offer and sale of Common Stock to the
         public at an offering price of at least $2.20 per share (such offering
         price being subject to proportional adjustment to reflect subdivisions,
         combinations, stock dividends and similar transactions affecting the
         number of outstanding shares of Common Stock) for an aggregate gross
         public offering price (calculated before deduction of underwriters'
         discounts and commissions) of at least $15,000,000 or (b) upon (i) the
         acquisition of all or substantially all the assets of the Company or
         (ii) an acquisition of the Company by another corporation or entity by
         consolidation, merger or other reorganization in which the holders of
         the Company's outstanding voting stock immediately prior to such
         transaction own, immediately after such transaction, securities
         representing less than fifty percent (50%) or more of the voting power
         of the corporation or other entity surviving such transaction.

                  3.6 Waiver. Each Rights Holder hereby confirms its waiver of
         any right of first refusal it may have had to purchase such Rights
         Holder's Pro Rata Share of the Issued Preferred Stock.

         4.       ASSIGNMENT AND AMENDMENT.

                  4.1 Assignment. Notwithstanding anything herein to the
         contrary:

                           (a) Information Rights. The rights of an Investor
                  under Section 1.1 or 1.2 or 1.4 hereof may be assigned only to
                  (i) a party who acquires from an Investor (or an Investor's
                  permitted assigns) at least 200,000 shares of Series A Stock,
                  Series B Stock or Series C Stock subject to this Agreement
                  and/or 100,000 shares (on an as-converted basis) of
                  Registrable Securities issued upon conversion

                  thereof or (ii) a partner, member or stockholder of an
                  Investor who acquires at least 100,000 shares of Series A
                  Stock, Series B Stock, or Series C Stock subject to this

                  5.8 Counterparts. This Agreement may be executed in
         counterparts, each of which shall be deemed an original, but all of
         which together shall constitute one and the same instrument.

                  5.9 Costs And Attorneys' Fees. In the event that any action,
         suit or other proceeding is instituted concerning or arising out of
         this Agreement or any transaction contemplated hereunder, the

         fees incurred in each such action, suit or other proceeding, including
         any and all appeals or petitions therefrom.

                  5.10 Adjustments for Stock Splits, Etc. Wherever in this
         Agreement there is a reference to a specific number of shares of Common
         Stock or Preferred Stock of the Company of any class or series, then,

         of such class or series of stock, the specific number of shares so
         referenced in this Agreement shall automatically be proportionally
         adjusted to reflect the affect on the outstanding shares of such class
         or series of stock by such subdivision, combination or stock dividend.

                  5.12 Arbitration Any disputes between the Company and the
         Investors with respect to this Agreement shall be settled by binding,
         final arbitration in accordance with the commercial arbitration rules
         of the American Arbitration Association then in effect (the "AAA
         Rules"). Any arbitration proceeding shall be conducted in Denver, CO.
         The following arbitration provisions shall govern over any conflicting
         rules which may now or hereafter be contained in the AAA Rules. Any
         judgment upon the award rendered by the arbitrator may be entered in
         any court having jurisdiction over the subject matter thereof. The
         arbitrator shall have the authority to grant any equitable and legal
         remedies that would be available.

                       (a) Any such arbitration shall be conducted before a
                  single arbitrator who shall be compensated for his or her
                  services at a rate to be determined by the parties or by the
                  American Arbitration Association, but based upon reasonable
                  hourly or daily consulting rates for the arbitrator in the
                  event the parties are not able to agree upon his or her rate
                  of compensation.

                       (b) The AAA Rules for the selection of the arbitrator
                  shall be followed.

                       (c) Each party to such arbitration shall each advance an
                  equal portion of the initial compensation to be paid to the
                  arbitrator in any such arbitration and an equal portion of the
                  costs of transcripts and other normal and regular expenses of
                  the arbitration proceedings; provided, however, that the
                  arbitrator shall have the discretion to grant to the
                  prevailing party in any arbitration an award of attorneys'
                  fees and costs, and all costs of arbitration.

                       (d) The parties shall be entitled to conduct discovery
                  proceedings in accordance with the provisions of the Federal
                  Rules of Civil Procedure, subject to any limitation imposed by
                  the arbitrator.

                       (e) For any claim submitted to arbitration, the burden of
                  proof shall be as it would be if the claim were litigated in a
                  judicial proceedings.

                       (f) Upon the conclusion of any arbitration proceeding
                  hereunder, the arbitrator shall render findings of fact and
                  conclusions of law and a written opinion setting forth the
                  basis and reasons for any decision reached by him or her and
                  shall deliver such documents to each party to this Agreement
                  along with a signed copy of the award.

                       (g) The arbitrator chosen in accordance with these
                  provisions shall not have the power to alter, amend or
                  otherwise affect the terms of these arbitration provisions or
                  the provisions of this Agreement.

                       (h) The parties acknowledge that, except as specifically
                  provided in this Agreement, no other action need be taken by
                  either party before proceeding directly in accordance with the
                  provisions of this Section.

                       (i) The arbitration provisions set forth in this Section
                  5.12 are intended by the parties to be exclusive for all
                  purposes and applicable to each and every controversy, dispute
                  and/or claim in any manner arising out of or relating to this
                  Agreement, the meaning, application and/or interpretation of
                  this Agreement, any breach hereof and/or any voluntary or
                  involuntary termination of this Agreement with or without
                  cause, including, without limitation, any such controversy,
                  dispute and/or claim which, if pursued through any state or
                  federal court or administrative agency, would arise at law, in
                  equity and/or pursuant to statutory, regulatory and/or common
                  law rules, regardless of whether any such dispute, controversy
                  and/or claim would arise in and/or from contract, tort or any
                  other legal and/or equitable theory or basis. The prevailing
                  party in any action instituted pursuant to this Section
                  5.13(i),

                  this Section 5.13, shall be entitled to recover from the other
                  party its reasonable attorneys' fees and other expenses
                  incurred in such litigation.

                  5.13 Effectiveness; Termination of the Original Agreement This

         this Agreement, the Third Amended Agreement shall be terminated and

delivering an appropriate confirmation certificate to the Lender. The Borrower
shall repay all Advances even if the Lender does not receive such confirmation
and even if the person requesting an Advance was not in fact authorized to do
so. Any request for an Advance, whether written or telephonic, shall be deemed
to be a representation by the Borrower that the conditions set forth in Section
4.2 have been satisfied as of the time of the request.

         Section 2.2 Interest; Minimum Interest Charge; Default Interest; Usury.

                  (a) INTEREST. Except as set forth in Sections 2.2(c) and
2.2(e), the outstanding principal balance of the Note shall bear interest at the
Floating Rate. Interest accruing on the Note shall be due and payable in arrears
on the first day of each month.

                  (b) MINIMUM INTEREST CHARGE. Notwithstanding the interest
payable pursuant to Section 2.2(a), the Borrower shall pay to the Lender
interest of not less than $15,000 per calendar quarter (the "Minimum Interest
Charge") during the term of this Agreement, and the Borrower shall pay any
deficiency between the Minimum Interest Charge and the amount of interest
otherwise calculated under Sections 2.2(a) and 2.2(c) in arrears in the manner
provided in Section 2.4. The Minimum Interest Charge for each period of less
than a full calendar quarter shall be prorated for the number of days during
such quarter that this Agreement is in effect.

                  (c) DEFAULT INTEREST RATE. At any time during any Default
Period, in the Lender's sole discretion and without waiving any of its other
rights and remedies, the principal of the Advances outstanding from time to time
shall bear interest at the Default Rate, effective for any periods designated by
the Lender from time to time during that Default Period.

                  (d) PARTICIPATIONS. If any Person shall acquire a
participation in the Advances under this Agreement, the Borrower shall be
obligated to the Lender to pay the full amount of all interest calculated under
this Agreement, along with all other fees, charges and other amounts due under
this Agreement, regardless if such Person elects to accept interest with respect
to its participation at a lower rate than the Floating Rate, or otherwise elects
to accept less than its prorata share of such fees, charges and other amounts
due under this Agreement.

                  (e) USURY. In any event no rate change shall be put into
effect which would result in a rate greater than the highest rate permitted by
law. Notwithstanding anything to the contrary contained in any Loan Document,
all agreements which either now are or which shall become agreements between the
Borrower and the Lender are hereby limited so that in no contingency or event
whatsoever shall the total liability for payments in the nature of interest,
additional interest and other charges exceed the applicable limits imposed by
any applicable usury laws. If any payments in the nature of interest, additional
interest and other charges made under any Loan Document are held to be in excess
of the limits imposed by any applicable usury laws, it is agreed that any such
amount held to be in excess shall be considered payment of principal hereunder,
and the indebtedness evidenced hereby shall be reduced by such amount so that
the total liability for payments in the nature of interest, additional interest
and other charges shall not exceed the applicable limits imposed by any
applicable usury laws, in compliance with the desires of the Borrower and the
Lender. This provision shall never be superseded or waived and shall control
every other provision of the Loan Documents and all agreements between the
Borrower and the Lender, or their successors and assigns.

                  (a) "Capital Adequacy Rule" means any law, rule, regulation,
guideline, directive, requirement or request regarding capital adequacy, or the
interpretation or administration thereof by any governmental or regulatory
authority, central bank or comparable agency, whether or not having the force of
law, that applies to any Related Lender. Such rules include rules requiring
financial institutions to maintain total capital in amounts based upon
percentages of outstanding loans, binding loan commitments and letters of
credit.

                  (b) "Return", for any period, means the return as determined
by such Related Lender on the Advances based upon its total capital requirements
and a reasonable attribution formula that takes account of the Capital Adequacy
Rules then in effect. Return may be calculated for each calendar quarter and for
the shorter period between the end of a calendar quarter and the date of
termination in whole of this Agreement.

<PAGE>   11




                  (c) "Rule Change" means any change in any Capital Adequacy
Rule occurring after the date of this Agreement, but the term does not include
any changes in applicable requirements that at the date of this Agreement are
scheduled to take place under the existing Capital Adequacy Rules or any
increases in the capital that any Related Lender is required to maintain to the
extent that the increases are required due to a regulatory authority's
assessment of the financial condition of such Related Lender.

                  (d) "Related Lender" includes (but is not limited to) the
Lender, any parent corporation of the Lender and any assignee of any interest of
the Lender hereunder and any participant in the loans made hereunder.

Certificates of any Related Lender sent to the Borrower from time to time
claiming compensation under this Section 2.5, stating the reason therefor and
setting forth in reasonable detail the calculation of the additional amount or
amounts to be paid to the Related Lender hereunder to restore its Return shall
be conclusive absent manifest error. In determining such amounts, the Related
Lender may use any reasonable averaging and attribution methods.

         Section 2.6 Voluntary Prepayment; Reduction of the Maximum Line;
Termination of the Credit Facility by the Borrower. Except as otherwise provided
herein, the Borrower may prepay the Advances in whole at any time or in part
from time to time. The Borrower may terminate the Credit Facility in whole (but
not in part) at any time and, subject to payment and performance of all the
Borrower's obligations to the Lender, may obtain any release or termination of
the Security Interest to which the Borrower is otherwise entitled by law by (i)
giving at least 30 days' prior written notice to the Lender of the Borrower's
intention to terminate this Agreement; and (ii) paying the Lender a prepayment
fee equal to the product of the Prepayment Penalty and the Maximum Line if the
Borrower terminates this Agreement effective as of any date other than the
Maturity Date, unless the Credit Facility is refinanced with the proceeds of a
loan from an Affiliate of the Lender or is refinanced within 90 days of a
request by any Related Lender for compensation under Section 2.5. The Borrower
may decrease the Maximum Line at any time by (i) giving at least 30 days' prior
written notice to the Lender of the Borrower's intention to decrease the Maximum
Line, which notice shall set forth the exact amount of the reduction; (ii)
prepaying all Advances in excess of the decreased amount of the Maximum Line
(taking into effect such reduction); and (iii) paying the Lender a prepayment
fee equal to the product of the Prepayment Penalty and the amount by which the
Maximum Line is decreased. Any reduction in the Maximum Line must be in an
amount not less than $100,000 or an integral multiple thereof. If the Borrower
reduces the Maximum Line to zero, all Obligations shall be immediately due and
payable. Borrower acknowledges and agrees that Lender shall not release any
Security Interest in the Collateral unless and until Borrower has paid and
performed all of Borrower's obligations to Lender and this Agreement has been
terminated.

         Section 2.7 Mandatory Prepayment. Without notice or demand, if the
outstanding principal balance of the Advances shall at any time exceed the
Borrowing Base, the Borrower shall immediately prepay the Advances to the extent
necessary to eliminate such excess. Any payment received by the Lender under
this Section 2.7 or under Section 2.6 may be applied to the


                                     -11-

<PAGE>   12



Obligations, in such order and in such amounts as the Lender, in its discretion,
may from time to time determine.

         Section 2.8 Payment. All payments to the Lender shall be made in
immediately available funds and shall be applied to the Obligations one Banking
Day after receipt by the Lender. The Lender may hold all payments not
constituting immediately available funds for three (3) days (consisting of two
Banking Days for collection and one Banking Day for processing) before applying
them to the Obligations. Notwithstanding anything in Section 2.1, the Borrower
hereby authorizes the Lender, in its discretion at any time or from time to time
without the Borrower's request and even if the conditions set forth in Section
4.2 would not be satisfied, to make an Advance in an amount equal to the portion
of the Obligations from time to time due and payable.

         Section 2.9 Payment on Non-Banking Days. Whenever any payment to be
made hereunder shall be stated to be due on a day which is not a Banking Day,
such payment may be made on the next succeeding Banking Day, and such extension
of time shall in such case be included in the computation of interest on the
Advances or the fees hereunder, as the case may be.

         Section 2.10 Use of Proceeds. The Borrower shall use the proceeds of
Advances for ordinary working capital purposes and to lease or purchase capital
assets.

         Section 2.11 Liability Records. The Lender may maintain from time to
time, at its discretion, liability records as to the Obligations. All entries
made on any such record shall be presumed correct until the Borrower establishes
the contrary. Upon the Lender's demand, the Borrower will admit and certify in
writing the exact principal balance of the Obligations that the Borrower then
asserts to be outstanding. Any billing statement or accounting rendered by the
Lender shall be conclusive and fully binding on the Borrower unless the Borrower
gives the Lender specific written notice of exception within 60 days after
receipt.

                                   ARTICLE III
                      Security Interest; Occupancy; Setoff

         Section 3.1 Grant of Security Interest. The Borrower hereby pledges,
assigns and grants to the Lender a security interest (collectively referred to
as the "Security Interest") in the Collateral, as security for the payment and
performance of the Obligations.

         Section 3.2 Notification of Account Debtors and Other Obligors. The
Lender may at any time during a Default Period notify any account debtor or
other person obligated to pay the amount due that such right to payment has been
assigned or transferred to the Lender for security and shall be paid directly to
the Lender. The Borrower will join in giving such notice if the Lender so
requests. At any time after the Borrower or the Lender gives such notice to an
account debtor or other obligor, the Lender may, but need not, in the Lender's
name or in the Borrower's name, (a) demand, sue for, collect or receive any
money or property at any time payable or receivable on account of, or securing,
any such right to payment, or grant any extension to, make any compromise or
settlement with or otherwise agree to waive, modify, amend or change the


                                      -12-

<PAGE>   13


obligations (including collateral obligations) of any such account debtor or
other obligor; and (b) as the Borrower's agent and attorney-in-fact, notify the
United States Postal Service to change the address for delivery of the
Borrower's mail to any address designated by the Lender, otherwise intercept the
Borrower's mail, and receive, open and dispose of the Borrower's mail, applying
all Collateral as permitted under this Agreement and holding all other mail for
the Borrower's account or forwarding such mail to the Borrower's last known
address.

         Section 3.3 Assignment of Insurance. As additional security for the
payment and performance of the Obligations, the Borrower hereby assigns to the
Lender any and all monies (including, without limitation, proceeds of insurance
and refunds of unearned premiums) due or to become due under, and all other
rights of the Borrower with respect to, any and all policies of insurance now or
at any time hereafter covering the Collateral or any evidence thereof or any
business records or valuable papers pertaining thereto, and the Borrower hereby
directs the issuer of any such policy to pay all such monies directly to the
Lender. At any time, whether or not a Default Period then exists, the Lender may
(but need not), in the Lender's name or in the Borrower's name, execute and
deliver proof of claim, receive all such monies, endorse checks and other
instruments representing payment of such monies, and adjust, litigate,
compromise or release any claim against the issuer of any such policy.

         Section 3.4 Occupancy.


                  (a) The Borrower hereby irrevocably grants to the Lender the
right to take possession of the Premises at any time during a Default Period.

                  (b) The Lender may use the Premises only to hold, process,
manufacture, sell, use, store, liquidate, realize upon or otherwise dispose of
goods that are Collateral and for other purposes that the Lender may in good
faith deem to be related or incidental purposes.

                  (c) The Lender's right to hold the Premises shall cease and
terminate upon the earlier of (i) payment in full and discharge of all
Obligations and termination of the Commitment, (ii) final sale or disposition of
all goods constituting Collateral and delivery of all such goods to purchasers,
and (iii) the termination of all Default Periods giving rise to such right.

                  (d) The Lender shall not be obligated to pay or account for
any rent or other compensation for the possession, occupancy or use of any of
the Premises; provided, however, that if the Lender does pay or account for any
rent or other compensation for the possession, occupancy or use of any of the
Premises, the Borrower shall reimburse the Lender promptly for the full amount
thereof. In addition, the Borrower will pay, or reimburse the Lender for, all
taxes, fees, duties, imposts, charges and expenses at any time incurred by or
imposed upon the Lender by reason of the execution, delivery, existence,
recordation, performance or enforcement of this Agreement or the provisions of
this Section 3.4.

         Section 3.5 License. Without limiting the generality of the Patent
Security Agreement or Copyright Security Agreement, the Borrower hereby grants
to the Lender a non-exclusive, worldwide and royalty-free license to use or
otherwise exploit all trademarks, franchises, trade


                                      -13-

names, copyrights and patents of the Borrower for the purpose of selling,
leasing or otherwise disposing of any or all Collateral during any Default
Period.

         Section 3.6 Financing Statement. A carbon, photographic or other
reproduction of this Agreement or of any financing statements signed by the
Borrower is sufficient as a financing statement and may be filed as a financing

         Section 3.7 Setoff. The Borrower agrees that the Lender may at any time
or from time to time, at its sole discretion and without demand and without
notice to anyone, setoff any liability owed to the Borrower by the Lender,
whether or not due, against any Obligation, whether or not due. In addition,
each other Person holding a participating interest in any Obligations shall have
the right to appropriate or setoff any deposit or other liability then owed by
such Person to the Borrower, whether or not due, and apply the same to the
payment of said participating interest, as fully as if such Person had lent
directly to the Borrower the amount of such participating interest.

         The Borrower represents and warrants to the Lender as follows:

         Section 5.1 Corporate Existence and Power; Name; Chief Executive
Office; Inventory and Equipment Locations; Tax Identification Number. The
Borrower is a corporation, duly organized, validly existing and in good standing
under the laws of the State of Delaware and is duly licensed or qualified to
transact business in Colorado and all other jurisdictions where the character of
the property owned or leased or the nature of the business transacted by it
makes such licensing or qualification necessary. The Borrower has all requisite
power and authority, corporate or otherwise, to conduct its business, to own its
properties and to execute and deliver, and to perform all of its obligations
under, the Loan Documents. During its existence, the Borrower has done business
solely under the names set forth in Schedule 5.1 hereto and such


                                      -16-

<PAGE>   17


other names as the Borrower shall notify the Lender in writing not less than 30
days prior to the use of such names. The Borrower's chief executive office and
principal place of business is located at the address set forth in Schedule 5.1
hereto, and all of the Borrower's records relating to its business or the
Collateral are kept at that location. All Inventory and Equipment is located at
that location or at one of the other locations set forth in Schedule 5.1 hereto,
or at such other locations as the Borrower shall notify the Lender in writing
not less than 30 days prior to the use of such other locations. The Borrower's
tax identification number is correctly set forth in Section 3.6 hereto.

         Section 5.2 Authorization of Borrowing; No Conflict as to Law or
Agreements. The execution, delivery and performance by the Borrower of the Loan
Documents and the borrowings from time to time hereunder have been duly
authorized by all necessary corporate action and do not and will not (i) require
any consent or approval of the Borrower's stockholders; (ii) require any
authorization, consent or approval by, or registration, declaration or filing
with, or notice to, any governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, or any third party, except such
authorization, consent, approval, registration, declaration, filing or notice as
has been obtained, accomplished or given prior to the date hereof; (iii) violate
any provision of any law, rule or regulation (including, without limitation,
Regulation X of the Board of Governors of the Federal Reserve System) or of any
order, writ, injunction or decree presently in effect that is applicable to the
Borrower or of the Borrower's articles of incorporation or bylaws and that is
material to the Borrower's business; (iv) result in a breach of or constitute a
default under any indenture or loan or credit agreement or any other material
agreement, lease or instrument to which the Borrower is a party or by which it
or its properties may be bound or affected; or (v) result in, or require, the
creation or imposition of any mortgage, deed of trust, pledge, lien, security
interest or other charge or encumbrance of any nature (other than the Security
Interest) upon or with respect to any of the properties now owned or hereafter
acquired by the Borrower.

         Section 5.3 Legal Agreements. This Agreement constitutes and, upon due
execution by the Borrower, the other Loan Documents will constitute the legal,
valid and binding obligations of the Borrower, enforceable against the Borrower
in accordance with their respective terms except as enforceability is limited by
bankruptcy, insolvency, reorganization, moratorium or other laws relating to or
affecting generally the enforcement of creditors' rights and except to the
extent that availability of specific performance or injunctive relief is subject
to the discretion of the court before which any proceeding therefor may be
brought.

         Section 5.4 Subsidiaries. Except as set forth in Schedule 5.4 hereto,
the Borrower has no Subsidiaries.

         Section 5.5 Financial Condition; No Adverse Change. The Borrower has
heretofore furnished to the Lender its unaudited financial statement for its
fiscal year ended March 31, 1999 which statement fairly presents the Borrower's
financial condition on this date thereof and the results of its operations and
cash flows for the periods then ended and were prepared in accordance with
generally accepted accounting principles. Since the date of the most recent


                                      -17-

<PAGE>   18


financial statements, there has been no material adverse change in the
Borrower's business, properties or condition (financial or otherwise).

         Section 5.6 Litigation. There are no actions, suits or proceedings
pending or, to the Borrower's knowledge, threatened against or affecting the
Borrower or any of its Affiliates or the properties of the Borrower or any of
its Affiliates before any court or governmental department, commission, board,
bureau, agency or instrumentality, domestic or foreign, which, if determined
adversely to the Borrower or any of its Affiliates, would have a material
adverse effect on the financial condition, properties or operations of the
Borrower or any of its Affiliates.

         Section 5.7 Regulation U. The Borrower is not engaged in the business
of extending credit for the purpose of purchasing or carrying margin stock
(within the meaning of Regulation U of the Board of Governors of the Federal
Reserve System), and no part of the proceeds of any Advance 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.

         Section 5.8 Taxes. The Borrower and its Affiliates have paid or
remitted or caused to be paid or remitted to the proper authorities when due all
federal, state and local taxes required to be paid or remitted by each of them
or, to the extent that any taxes are being contested in good faith, adequate
reserves have been established therefore in accordance with GAAP. The Borrower
and its Affiliates have filed all federal, state and local tax returns which to
the knowledge of the officers of the Borrower or any Affiliate, as the case may
be, are required to be filed, and the Borrower and its Affiliates have paid or
caused to be paid to the respective taxing authorities all taxes as shown on
said returns or on any assessment received by any of them to the extent such
taxes have become due.

         Section 5.9 Titles and Liens. The Borrower has good and marketable
title to all Collateral described in the collateral reports provided to the
Lender and all other Collateral, properties and assets reflected in the latest
financial statements referred to in Section 5.5 and all proceeds thereof, free
and clear of all mortgages, security interests, liens and encumbrances, except
for (i) provision of existing building and zoning laws; (ii) liens for current
taxes not yet due; and (iii) Permitted Liens. No financing statement naming the
Borrower as debtor is on file in any office except to perfect only Permitted
Liens.

         Section 5.10 Plans. Except as disclosed to the Lender in writing prior
to the date hereof, neither the Borrower nor any of its Affiliates maintains or
has maintained any Plan. Neither the Borrower nor any Affiliate has received any
notice or has any knowledge to the effect that it is not in full compliance with
any of the requirements of ERISA. No Reportable Event or other fact or
circumstance which may have an adverse effect on the Plan's tax qualified status
exists in connection with any Plan. Neither the Borrower nor any of its
Affiliates has:

                  (a) Any accumulated funding deficiency within the meaning of
ERISA; or

                  (b) Any liability or knows of any fact or circumstances which
could result in any liability to the Pension Benefit Guaranty Corporation, the
Internal Revenue Service, the


                                      -18-

<PAGE>   19



Department of Labor or any participant in connection with any Plan (other than
accrued benefits which or which may become payable to participants or
beneficiaries of any such Plan).

         Section 5.11 Default. The Borrower is in compliance with all provisions
of all agreements, instruments, decrees and orders to which it is a party or by
which it or its property is bound or affected, the breach or default of which
could reasonably be expected to have a material adverse effect on the Borrower's
financial condition, properties or operations.

         Section 5.12 Environmental Matters.

                  (a) Definitions. As used in this Agreement, the following
terms shall have the following meanings:

                           (i) "Environmental Law" means any federal, state,
                  local or other governmental statute, regulation, law or
                  ordinance dealing with the protection of human health and the
                  environment.

                  (b) To the Borrower's best knowledge, there are not present
in, on or under the Premises any Hazardous Substances in such form or quantity
as to create any liability or obligation for either the Borrower or the Lender
under common law of any jurisdiction or under any Environmental Law, and no
Hazardous Substances have ever been stored, buried, spilled, leaked, discharged,
emitted or released in, on or under the Premises in such a way as to create any
such liability.

                  (c) To the Borrower's best knowledge, the Borrower has not

noncompliance with any Environmental Law or any license, permit or other
authorization issued pursuant thereto. To the Borrower's best knowledge, no such
matter is threatened or impending.

                  (e) To the Borrower's best knowledge, the Borrower's

for the lawful and efficient operation of such businesses are in the Borrower's
possession and are in full force and effect. No permit required under any
Environmental Law is scheduled to expire within 12 months and to the Borrower's
best

knowledge there is no threat that any such permit will be withdrawn, terminated,
limited or materially changed.

                  (f) To the Borrower's best knowledge, the Premises are not and
never have been listed on the National Priorities List, the Comprehensive
Environmental Response, Compensation and Liability Information System or any
similar federal, state or local list, schedule, log, inventory or database.

                  (g) The Borrower has delivered to Lender all environmental
assessments, audits, reports, permits, licenses and other similar documents
describing or relating in any way to the Borrower's businesses, and all such
documents known to the Borrower relating in any way to the Premises.

         Section 5.13 Submissions to Lender. All financial and other information
provided to the Lender by or on behalf of the Borrower in connection with the
Borrower's request for the credit facilities contemplated hereby is true and
correct in all material respects and, as to projections, valuations or proforma
financial statements, present a good faith opinion as to such projections,
valuations and proforma condition and results.

         Section 5.14 Financing Statements. The Borrower has provided to the
Lender signed financing statements, which, when filed, will be sufficient to
perfect the Security Interest and the other security interests created by the
Security Documents to the extent that the Security Interest can be perfected by
the filing of financing statements. When such financing statements are filed in
the offices noted therein, the Lender will have a valid and perfected security
interest in all Collateral and all other collateral described in the Security
Documents which is capable of being perfected by filing financing statements.
None of the Collateral or other collateral covered by the Security Documents is
or will become a fixture on real estate, unless a sufficient fixture filing is
in effect with respect thereto.

         Section 5.15 Rights to Payment. Each right to payment and each
instrument, document, chattel paper and other agreement constituting or
evidencing Collateral or other collateral covered by the Security Documents is
(or, in the case of all future Collateral or such other collateral, will be when
arising or issued) the valid, genuine and legally enforceable obligation,
subject to no defense, setoff or counterclaim, of the account debtor or other
obligor named therein or in the Borrower's records pertaining thereto as being
obligated to pay such obligation except as enforceability is limited by
bankruptcy, insolvency, reorganization, moratorium or other laws relating to or
affecting generally the enforcement of creditors' rights and except to the
extent that availability of specific performance or injunctive relief is subject
to the discretion of the court before which any proceeding therefor may be
brought.

assignment to account debtors and other obligors. The Lender may also at any

verify accounts.

         Section 6.4 Compliance with Laws.


                  (a) Borrower will (i) comply with the requirements of
applicable laws and regulations, the non-compliance with which would materially
and adversely affect its business or its financial condition and (ii) use and
keep the Collateral, and require that others use and keep the Collateral, only
for lawful purposes, without violation of any federal, state or local law,
statute or ordinance.

                  (b) Without limiting the foregoing undertakings, the Borrower
specifically agrees that it will comply with all applicable Environmental Laws
and obtain and comply with all permits, licenses and similar approvals required
by any Environmental Laws, and will not generate, use, transport, treat, store
or dispose of any Hazardous Substances in such a manner as to create any
liability or obligation under the common law of any jurisdiction or any
Environmental Law.

         Section 6.5 Payment of Taxes and Other Claims. The Borrower will pay or
discharge, when due, (a) all taxes, assessments and governmental charges levied
or imposed upon it or upon its income or profits, upon any properties belonging
to it (including, without limitation, the Collateral) or upon or against the
creation, perfection or continuance of the Security Interest, prior to the date
on which penalties attach thereto, (b) all federal, state and local taxes
required to be paid or remitted by it, and (c) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien or charge
upon any properties of the Borrower; provided, that the Borrower shall not be
required to pay any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which proper reserves have been made.

         Section 6.6 Maintenance of Properties.

                  (a) The Borrower will keep and maintain the Collateral, the
other collateral covered by the Security Documents and all of its other
properties necessary or useful in its business in good condition, repair and
working order (normal wear and tear excepted) and will from time to time replace
or repair any worn, defective or broken parts; provided, however, that nothing
in this Section 6.6 shall prevent the Borrower from discontinuing the operation
and maintenance of any of its properties if such discontinuance is desirable in
the conduct of the Borrower's business and not disadvantageous in any material
respect to the Lender.

                  (b) The Borrower will defend the Collateral against all claims
or demands of all persons (other than the Lender) claiming the Collateral or any
interest therein.

         Section 6.7 Insurance. The Borrower will obtain and at all times
maintain insurance with insurers believed by the Borrower to be responsible and
reputable, in such amounts and against such risks as may from time to time be
reasonably required by the Lender, but in all events in such amounts and against
such risks as is usually carried by companies engaged in similar business and
owning similar properties in the same general areas in which the Borrower
operates. Without limiting the generality of the foregoing, the Borrower will at
all times maintain business interruption insurance including coverage for force
majeure and keep all tangible Collateral insured against risks of fire
(including so-called extended coverage), theft, collision (for Collateral
consisting of motor vehicles) and such other risks and in such amounts as the
Lender may reasonably request, with any loss payable to the Lender to the extent
of its interest, and all policies of such insurance shall contain a lender's
loss payable endorsement for the Lender's benefit acceptable to the Lender. All
policies of liability insurance required hereunder shall name the Lender as an
additional insured. The Lender agrees that the insurance policies presently held
by the Borrower, in the types and amounts set forth on Schedule 6.7 hereto, are
reasonable based on the Lender's knowledge of the Borrower's current business.

         Section 6.8 Preservation of Existence. The Borrower will preserve and
maintain its existence and all of its rights, privileges and franchises
necessary or desirable in the normal conduct of its business and shall conduct
its business in an orderly, efficient and regular manner.

         Section 6.9 Delivery of Instruments, Etc. Upon request by the Lender,
the Borrower will promptly deliver to the Lender in pledge all instruments,
documents and chattel papers constituting Collateral, duly endorsed or assigned
by the Borrower.

         Section 6.10 Collateral Account.

                  (a) If, notwithstanding the instructions to debtors to make
payments to the Lockbox, the Borrower receives any payments on Receivables, the
Borrower shall deposit such payments into the Collateral Account. Until so
deposited, the Borrower shall hold all such payments in trust for and as the
property of the Lender and shall not commingle such payments with any of its
other funds or property.

                  (b) Amounts deposited in the Collateral Account shall not bear
interest and shall not be subject to withdrawal by the Borrower, except after
full payment and discharge of all Obligations.

                  (c) All deposits in the Collateral Account shall constitute
proceeds of Collateral and shall not constitute payment of the Obligations.
After allowing two Banking Days for collection of items deposited in the
Collateral Account, the Borrower authorizes the Lender to transmit deposited
funds in the amount of the deposit to the payment of the Obligations, in any
order or manner of application satisfactory to the Lender (and deposits shall be
applied to the Obligations after allowing one additional Business Day for
processing), by transferring such funds to the Lender's general account
maintained with Norwest Bank Minnesota, N.A., ABA #091000019, Account No.
635-5010053.

<PAGE>   26


                  (d) All items deposited in the Collateral Account shall be
subject to final payment. If any such item is returned uncollected, the Borrower
will promptly pay the Lender, or, for items deposited in the Collateral Account,
the bank maintaining such account, the amount of that item, or such bank at its
discretion may charge any uncollected item to the Borrower's commercial account
or other account. The Borrower shall be liable as an endorser on all items
deposited in the Collateral Account, whether or not in fact endorsed by the
Borrower.

         Section 6.11 Performance by the Lender. If the Borrower at any time
fails to perform or observe any of the foregoing covenants contained in this
Article VI or elsewhere herein, and if such failure shall continue for a period
of ten calendar days after the Lender gives the Borrower written notice thereof
(or in the case of the agreements contained in Sections 6.5, 6.7 and 6.10,
immediately upon the occurrence of such failure, without notice or lapse of
time), the Lender may, but need not, perform or observe such covenant on behalf
and in the name, place and stead of the Borrower (or, at the Lender's option, in
the Lender's name) and may, but need not, take any and all other actions which
the Lender may reasonably deem necessary to cure or correct such failure
(including, without limitation, the payment of taxes, the satisfaction of
security interests, liens or encumbrances, the performance of obligations owed
to account debtors or other obligors, the procurement and maintenance of
insurance, the execution of assignments, security agreements and financing
statements, and the endorsement of instruments); and the Borrower shall
thereupon pay to the Lender on demand the amount of all monies expended and all
costs and expenses (including reasonable attorneys' fees and legal expenses)
incurred by the Lender in connection with or as a result of the performance or
observance of such agreements or the taking of such action by the Lender,
together with interest thereon from the date expended or incurred at the
Floating Rate. To facilitate the Lender's performance or observance of such
covenants of the Borrower, the Borrower hereby irrevocably appoints the Lender,
or the Lender's delegate, acting alone, as the Borrower's attorney in fact
(which appointment is coupled with an interest) with the right (but not the
duty) from time to time to create, prepare, complete, execute, deliver, endorse
or file in the name and on behalf of the Borrower any and all instruments,
documents, assignments, security agreements, financing statements, applications
for insurance and other agreements and writings required to be obtained,
executed, delivered or endorsed by the Borrower under this Section 6.12.

         Section 6.12 Minimum Capital. The Borrower will maintain, as of each

On or before March 31, 2000, the Borrower and the Lender shall work in good
faith to agree on new covenant levels for Minimum Capital for periods after such
date, but if the Borrower and the Lender do not agree, the Lender may, but is
not obligated to, designate the required Minimum Capital for the last day of
each month after March 31, 2000, which amounts shall be equal to the sum of (a)
$250,000 multiplied by the number of months such day is past March 31, 2000 (for
example, December 31, 2000 is nine months past March 31, 2000; thus the amount
calculated under this clause (a) for December 31, 2000 is $2,250,000) plus (b)
the greater of (1) the Borrower's actual Capital as of March 31, 2000 or (2)
$2,750,000. The failure by the Borrower to maintain the designated amounts shall
constitute an Event of Default.

         Section 6.13 Minimum Net Income. The Borrower will achieve as of each
date described below, fiscal year-to-date Net Income of not less than the amount
set forth opposite such date:

On or before March 31, 2000, the Borrower and the Lender shall work in good
faith to agree on new covenant levels for Net Income for periods after such
date, but if the Borrower and the Lender do not agree, the Lender may, but is
not obligated to, designate the required fiscal year-to-date Net Income for each
quarter after March 31, 2000, which amounts shall be equal to, for each quarter
ending June 30, $750,000; for each quarter ending September 30, $1,500,000; for
each quarter ending December 31, $2,250,000; and for each quarter ending March

Documents (but any failure to request or assure that the Borrower executes,
delivers or endorses any such item shall not affect or impair the validity,

endorsed in a similar context or on a prior occasion).

         Section 9.5 Collateral. This Agreement does not contemplate a sale of
accounts, contract rights or chattel paper, and, as provided by law, the
Borrower is entitled to any surplus and shall remain liable for any deficiency.

otherwise preserve, protect, insure or care for any Collateral. The Lender shall
not be obligated to preserve any rights the Borrower may have against prior

         Section 9.7 Indemnity. In addition to the payment of expenses pursuant
to Section 9.6, the Borrower agrees to indemnify, defend and hold harmless the
Lender, and any of its participants, parent corporations, subsidiary
corporations, affiliated corporations, successor corporations, and all present
and future officers, directors, employees, attorneys and agents of the foregoing
(the "Indemnitees") from and against any of the following (collectively,
"Indemnified Liabilities"):

                  (a) any and all transfer taxes, documentary taxes, assessments
or charges made by any governmental authority by reason of the execution and
delivery of the Loan Documents or the making of the Advances;

                  (b) any claims, loss or damage to which any Indemnitee may be
subjected if any representation or warranty contained in Section 5.12 proves to
be incorrect in any respect or as a result of any violation of the covenant
contained in Section 6.4(b); and

                  (c) any and all other liabilities, losses, damages, penalties,
judgments, suits, claims, costs and expenses of any kind or nature whatsoever
(including, without limitation, the reasonable fees and disbursements of
counsel) in connection with the foregoing and any other investigative,
administrative or judicial proceedings, whether or not such Indemnitee shall be
designated a party thereto, which may be imposed on, incurred by or asserted
against any such Indemnitee, in any manner related to or arising out of or in
connection with the making of the Advances and the Loan Documents or the use or
intended use of the proceeds of the Advances, provided that the Borrower, shall
not have any obligation to any Indemnitee hereunder with respect to Indemnified
Liabilities caused by or resulting from the willful misconduct or gross
negligence of such Indemnitee or the breach by such Indemnitee of this Agreement
or any other loan document.

If any investigative, judicial or administrative proceeding arising from any of
the foregoing is brought against any Indemnitee, upon such Indemnitee's request,
the Borrower, or counsel designated by the Borrower and satisfactory to the
Indemnitee, will resist and defend such action, suit or proceeding to the extent
and in the manner directed by the Indemnitee, at the Borrower's sole costs and
expense. Each Indemnitee will use its best efforts to cooperate in the defense
of any such action, suit or proceeding. If the foregoing undertaking to
indemnify, defend and hold


                                      -37-

harmless may be held to be unenforceable because it violates any law or public
policy, the Borrower shall nevertheless make the maximum contribution to the
payment and satisfaction of each of the Indemnified Liabilities which is
permissible under applicable law. The Borrower's obligation under this Section
9.7 shall survive the termination of this Agreement and the discharge of the
Borrower's other obligations hereunder.

         Section 9.8 Participants. The Lender and its participants, if any, are
not partners or joint venturers, and the Lender shall not have any liability or
responsibility for any obligation, act or omission of any of its participants.
All rights and powers specifically conferred upon the Lender may be transferred
or delegated to any of the Lender's participants, successors or assigns.

         Section 9.9 Execution in Counterparts. This Agreement and other Loan
Documents may be executed in any number of counterparts, each of which when so
executed and delivered shall be deemed to be an original and all of which
counterparts, taken together, shall constitute but one and the same instrument.

         Section 9.10 Binding Effect; Assignment; Complete Agreement; Exchanging
Information. The Loan Documents shall be binding upon and inure to the benefit
of the Borrower and the Lender and their respective successors and assigns,
except that the Borrower shall not have the right to assign its rights
thereunder or any interest therein without the Lender's prior written consent.
This Agreement, together with the Loan Documents, comprises the complete and
integrated agreement of the parties on the subject matter hereof and supersedes
all prior agreements, written or oral, on the subject matter hereof. Without
limiting the Lender's right to share information regarding the Borrower and its
Affiliates with the Lender's participants, accountants, lawyers and other
advisors, the Lender, WFC Holdings Corporation, and all direct and indirect
subsidiaries of WFC Holdings Corporation, may exchange any and all information
they may have in their possession regarding the Borrower and its Affiliates, and
the Borrower waives any right of confidentiality it may have with respect to
such exchange of such information.

         Section 9.11 Severability of Provisions. Any provision of this
Agreement which is prohibited or unenforceable shall be ineffective to the
extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof.

         Section 9.12 Headings. Article and Section headings in this Agreement

right to make or countermand withdrawals from the Collateral Account.

         3. The Borrower hereby pledges to and grants the Lender a security
interest in all funds on deposit in the Collateral Account from time to time and
all proceeds thereof, to secure payment of all of the Borrower's obligations to

                                SUPPORT AGREEMENT

         This Agreement, dated as of July 5, 1999, is made by Douglas Lehrmann
(the "Officer"), and CHAPARRAL NETWORK STORAGE, INC., formerly known as
Chaparral Technologies, Inc., a Delaware corporation (the "Borrower"), for the
benefit of WELLS FARGO BUSINESS CREDIT, INC., a Minnesota corporation (the
"Lender").

                                    Recitals

         The Lender and Borrower have entered into a Credit and Security
Agreement (together with all amendments, supplements and restatements, the
"Credit Agreement") dated as of July 5, 1999, pursuant to which the Lender has
agreed to make revolving advances and extend other financial accommodations to
or for the benefit of the Borrower.

         The Officer is the duly elected, qualified and acting Vice
President/Finance of the Borrower and is fully familiar with all of the
Borrower's business and financial affairs.

         To induce the Lender to make advances and extend other financial
accommodations to or for the account of the Borrower under the Credit Agreement
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Officer, the Borrower and the Lender agree as
follows:

         1. Definitions. Capitalized terms used in this Agreement which are not
defined in this Agreement have the meanings given to them in the Credit
Agreement.

         2. Officer to Dispose of Collateral. The Officer and the Borrower agree
that if (i) the Lender comes into possession of any or all of the tangible
Collateral or is collecting the Borrower's Accounts or otherwise disposing of
Collateral because an Event of Default has occurred, and (ii) the Lender has
given notice of an acceleration of all of the Obligations:

                  (a) if the Officer is still employed by the Borrower, the
         Borrower will, upon the Lender's request, cause the Officer so long as
         he is employed by the Borrower, to exert his best efforts and devote
         all of his regular working hours to obtain sales of the Collateral at
         the best commercially obtainable prices and terms and to collect the
         Accounts at their full face value to the extent commercially
         reasonable; and

                  (b) if the Officer ceases to be employed by the Borrower or
         has ceased to be employed by the Borrower, at the Lender's option and
         upon the Lender's request, the Officer shall assist the Lender as the
         Lender's independent contractor, for a period not to exceed 150 days,
         for the sole purpose of disposing of the Collateral and collecting the
         Accounts, or assisting the Lender in disposing of the Collateral and
         collecting the Accounts. During the period of such employment the
         Officer shall exert his best efforts and devote all of his regular


<PAGE>   2




         working hours to obtain sales of the Collateral at the best
         commercially obtainable prices and terms and to collect the Accounts at
         their full face value.

         3. Lender's Right to Terminate Officer's Employment. The Lender shall
have the right to terminate the Officer's employment or other assistance
described in Paragraph 2 hereof at any time on 30 days' notice, for any cause or
without cause.

         4. Officer's Compensation. The Officer's sole compensation for any
employment or assistance rendered pursuant to Paragraph 2(b) hereof shall be a
weekly salary paid at 115% of the average salary (on a weekly basis) paid to
such person by the Borrower in the twelve (12) months immediately preceding the
commencement of such employment or activities. Such compensation shall be
prorated for partial weeks of service.

         5. Officer Shall Not Bind Lender. In connection with such employment,
the Officer shall not have any authority to bind the Lender, except such
specific authority as the Lender may grant in writing.

         6. Lender's Remedies Against Officer; Liquidated Damages. Until
termination pursuant to Paragraph 9, if the Officer fails to comply with the
provisions of Paragraph 2 hereof, unless such failure occurs as a result of
death or mental or physical incapacity, the Officer shall pay the Lender
$50,000, as liquidated damages, but not as a penalty, because of the difficulty
of proving actual damages for the breach of promises of the type contained
herein. Such liquidated damages shall be immediately due and payable upon the
Officer's failure to comply with the provisions of Paragraph 2 above. In
addition, the Officer shall be liable for the Lender's costs and expenses
(including reasonable attorneys' fees and legal expenses) incurred in enforcing
the liquidated damages provision. In any event, however, the Officer shall not
be liable for more than the Lender's actual damages (excluding consequential and
punitive damages), plus the Lender's costs of enforcement of this Agreement.

         7. Officer Remains Liable for Fraud and Misrepresentation.
Notwithstanding paragraph 9 hereof, the Officer shall hold the Lender harmless
for any actual loss, cost, expense, claim and damage (including any reasonable
attorney fees but excluding consequential and punitive damages) arising out of
fraud or misrepresentation made by the Borrower or its agents with respect to
the Collateral or the Borrower's financial statements while the Officer is
employed by the Borrower or the Lender. This paragraph 7 shall remain in full
force and effect so long as any Obligations remain outstanding or until
otherwise agreed by an amendment to this Agreement signed by the Lender, the
Borrower and the Officer.

         8. Borrower to Find Replacement for Officer. If the Officer dies,
becomes mentally or physically incapacitated, or ceases to be employed by the
Borrower, the Borrower shall obtain a replacement for the Officer and the
Borrower shall use its best efforts to cause such replacement to execute a
support agreement substantially in the form of this Agreement.

<PAGE>   3



         9. Termination of Officer's Obligations. This Agreement shall remain in
full force and effect until

                  (a) the Credit Agreement is no longer outstanding and all
         Obligations have been paid in full; or

                  (b) except as set forth in Paragraph 7 hereof, the Officer
         shall have ceased to be employed by the Borrower for more than thirty
         (30) business days before the occurrence of the events described in
         clauses (i) and (ii) of Paragraph 2 hereof, and shall have given notice
         of such cessation of employment to the Lender at least thirty (30)
         business days before the occurrence of such events.

         10. Miscellaneous. The provisions of this Agreement are declared to be
severable. If any provision of this Agreement shall be held to be invalid,
illegal or unenforceable, such invalidity, illegality or unenforceability shall
not affect any other provisions of this Agreement. The Officer and the Borrower
waive notice of the Lender's acceptance hereof.

         11. Governing Law; Waiver of Jury Trial. This Agreement shall be
governed by and construed in accordance with the substantive laws (other than
conflict laws) of the State of Minnesota. THE PARTIES WAIVE ANY RIGHT OF TRIAL
BY JURY IN ANY CLAIM, COUNTERCLAIM, ACTION OR PROCEEDING BASED ON OR PERTAINING
TO THIS AGREEMENT.

         IN WITNESS WHEREOF, the Officer and the Borrower have executed this
Agreement as of the date first written above.

addition, the Officer shall be liable for the Lender's costs and expenses

                             SUBORDINATION AGREEMENT

         This Agreement, dated as of July 5, 1999, is made by William R. Childs
(the "Subordinated Creditor"), for the benefit of Wells Fargo Business Credit,
Inc., a Minnesota corporation (the "Lender").

         Chaparral Network Storage, Inc., formerly known as Chaparral
Technologies, Inc., a Delaware corporation (the "Borrower"), is now or hereafter
may be indebted to the Lender on account of loans or the other extensions of
credit or financial accommodations from the Lender to the Borrower, or to any
other person under the guaranty or endorsement of the Borrower.

         The Subordinated Creditor has made or may make loans or grant other
financial accommodations to the Borrower.

         As a condition to making any loan or extension of credit to the
Borrower, the Lender has required that the Subordinated Creditor subordinate the
payment of the Subordinated Creditor's loans and other financial accommodations
to the payment of any and all indebtedness of the Borrower to the Lender.
Assisting the Borrower in obtaining credit accommodations from the Lender and
subordinating his interests pursuant to the terms of this Agreement are in the
Subordinated Creditor's best interest.

         ACCORDINGLY, in consideration of the loans and other financial
accommodations that have been made and may hereafter be made by the Lender for
the benefit of the Borrower, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Subordinated
Creditor hereby agrees as follows:

         1. Definitions. As used herein, the following terms have the meanings
set forth below:

          "Availability" has the meaning given in the Credit Agreement.

          "Borrower Default" means a Default or Event of Default as defined in
     any agreement or instrument evidencing, governing, or issued in connection
     with Lender Indebtedness, including, but not limited to, the Credit
     Agreement, or any default under or breach of any such agreement or
     instrument.

          "Cash Flow" means the Borrower's fiscal year-to-date Net Income plus
     depreciation and amortization, plus other non-cash items including (without
     limitation) any deferred interest, less the sum of (a) Current Maturities
     of Long Term Debt and (b) unfinanced Capital Expenditures. Capitalized
     terms used in this definition and not defined in this Agreement shall have
     the meaning given in the Credit Agreement.

          "Credit Agreement" means the Credit and Security Agreement dated as of
     July 5, 1999, by and between the Borrower and the Lender, as the same may
     hereafter be amended, supplemented or restated from time to time.


<PAGE>   2





          "Current Maturities of Long Term Debt" as of a given date means the
     amount of the Borrower's long-term debt and capitalized leases which became
     due during the fiscal year-to-date period ending on the designated date.

          "Lender Indebtedness" means each and every debt, liability and
     obligation of every type and description which the Borrower may now or at
     any time hereafter owe to the Lender, whether such debt, liability or
     obligation now exists or is hereafter created or incurred, and whether it
     is or may be direct or indirect, due or to become due, absolute or
     contingent, primary or secondary, liquidated or unliquidated, or joint,
     several or joint and several, all interest thereon, all renewals,
     extensions and modifications thereof and any notes issued in whole or
     partial substitution therefor.

          "Subordinated Indebtedness" means all obligations arising under the
     Subordinated Note and each and every other debt, liability and obligation
     of every type and description which the Borrower may now or at any time
     hereafter owe to the Subordinated Creditor, whether such debt, liability or
     obligation now exists or is hereafter created or incurred, and whether it
     is or may be direct or indirect, due or to become due, absolute or
     contingent, primary or secondary, liquidated or unliquidated, or joint,
     several or joint and several.

          "Subordinated Note" means, collectively, all of the following: the
     Borrower's Promissory Note, dated as of January 27, 1999, in the original
     principal amount of $50,000, the Borrower's Promissory Note, dated as of
     March 1, 1999, in the original principal amount of $400,000, the Borrower's
     Promissory Note, dated as of March 18, 1999, in the original principal
     amount of $200,000, the Borrower's Promissory Note, dated as of April 1,
     1999, in the original principal amount of $200,000, and the Borrower's

     amount of $200,000, each payable to the Subordinated Creditor, and any
     other Promissory Note issued in the future by the Borrower payable to the
     Subordinated Creditor, provided such Promissory Note contains the legend
     set forth in Exhibit A hereto, together with all renewals, extensions and
     modifications thereof and any note or notes issued in substitution
     therefor.

         2. Subordination. The payment of all of the Subordinated Indebtedness
is hereby expressly subordinated to the extent and in the manner hereinafter set
forth to the payment in full of the Lender Indebtedness; and regardless of any
priority otherwise available to the Subordinated Creditor by law or by
agreement, the Lender shall hold a first security interest in all collateral
securing payment of the Lender Indebtedness (the "Collateral"), and any security
interest claimed therein (including any proceeds thereof) by the Subordinated
Creditor shall be and remain fully subordinate for all purposes to the security
interest of the Lender therein for all purposes whatsoever.

         3. Principal Payments. Until all of the Lender Indebtedness has been
paid in full, the Subordinated Creditor shall not, without the Lender's prior
written consent, demand, receive or accept any principal payment, from the
Borrower in respect of the Subordinated Indebtedness, or exercise any right of
or permit any setoff in respect of the Subordinated Indebtedness, except that
the



                                       -2-

<PAGE>   3




Subordinated Creditor may accept payments of principal under the Subordinated
Note within 30 days of the end of each fiscal quarter, so long as (a) no
Borrower Default has occurred and is continuing or will occur as a result of or
immediately following any such payment, (b) average Availability for the 90-day
period prior to such payment is greater than $200,000, (c) Availability after
such payment will be greater than $200,000, (d) the sum of such payment and all
prior payments to Subordinated Creditor and all of the Borrower's other
subordinated creditors during the fiscal year in which such payment is proposed
to be made will not exceed 70% of the Borrower's fiscal year-to-date Cash Flow,
and (e) the date of the proposed payment is on January 1, 2000 or thereafter.

         4. Interest Payments. Without the Lender's prior written consent, the
Subordinated Creditor shall not demand, receive or accept any interest payment
from the Borrower in respect of the Subordinated Indebtedness so long as any
Borrower Default exists or if a Borrower Default will occur as a result of or
immediately following such interest payment.

         5. Receipt of Prohibited Payments. If the Subordinated Creditor
receives any payment on the Subordinated Indebtedness that the Subordinated
Creditor is not entitled to receive under the provisions of this Agreement, the
Subordinated Creditor will hold the amount so received in trust for the Lender
and will forthwith turn over such payment to the Lender in the form received
(except for the endorsement of the Subordinated Creditor where necessary) for
application to then-existing Lender Indebtedness (whether or not due), in such
manner of application as the Lender may deem appropriate. If the Subordinated
Creditor exercises any right of setoff which the Subordinated Creditor is not
permitted to exercise under the provisions of this Agreement, the Subordinated
Creditor will promptly pay over to the Lender, in immediately available funds,
an amount equal to the amount of the claims or obligations offset. If the
Subordinated Creditor fails to make any endorsement required under this
Agreement, the Lender, or any of its officers or employees or agents on behalf
of the Lender, is hereby irrevocably appointed as the attorney-in-fact (which
appointment is coupled with an interest) for the Subordinated Creditor to make
such endorsement in the Subordinated Creditor's name.

         6. Action on Subordinated Debt. The Subordinated Creditor will not
commence any action or proceeding against the Borrower to recover all or any
part of the Subordinated Indebtedness, or join with any creditor (unless the
Lender shall so join) in bringing any proceeding against the Borrower under any
bankruptcy, reorganization, readjustment of debt, arrangement of debt
receivership, liquidation or insolvency law or statute of the federal or any
state government, or take possession of, sell, or dispose of any Collateral, or
exercise or enforce any right or remedy available to the Subordinated Creditor
with respect to any such Collateral, unless and until the Lender Indebtedness
has been paid in full.

         7. Action Concerning Collateral.

          (a) Notwithstanding any security interest now held or hereafter
     acquired by the Subordinated Creditor, the Lender may take possession of,
     sell, dispose of, and otherwise deal with all or any part of the
     Collateral, and may enforce any right or remedy available to it with
     respect to the Collateral, all without notice to or consent of the
     Subordinated Creditor except as specifically required by applicable law.

                                       -3-

<PAGE>   4





          (b) In addition, and without limiting the generality of the foregoing,
     if a Borrower Default has occurred and is continuing and the Borrower
     intends to sell any Collateral to an unrelated third party outside the
     ordinary course of business, the Subordinated Creditor shall, upon the
     Lender's request, execute and deliver to such purchaser such instruments as
     may reasonably be necessary to terminate and release any security interest
     or lien the Subordinated Creditor has in the Collateral to be sold.

          (c) The Lender shall have no duty to preserve, protect, care for,
     insure, take possession of, collect, dispose of, or otherwise realize upon
     any of the Collateral, and in no event shall the Lender be deemed the
     Subordinated Creditor's agent with respect to the Collateral. All proceeds
     received by the Lender with respect to any Collateral may be applied,
     first, to pay or reimburse the Lender for all costs and expenses (including
     reasonable attorneys' fees) incurred by the Lender in connection with the
     collection of such proceeds, and, second, to any indebtedness secured by
     the Lender's security interest in that Collateral in any order that it may
     choose.

         8. Bankruptcy and Insolvency. In the event of any receivership,
insolvency, bankruptcy, assignment for the benefit of creditors, reorganization
or arrangement with creditors, whether or not pursuant to bankruptcy law, the
sale of all or substantially all of the assets of the Borrower, dissolution,
liquidation or any other marshaling of the assets or liabilities of the
Borrower, the Subordinated Creditor will file all claims, proofs of claim or
other instruments of similar character necessary to enforce the obligations of
the Borrower in respect of the Subordinated Indebtedness and will hold in trust
for the Lender and promptly pay over to the Lender in the form received (except
for the endorsement of the Subordinated Creditor where necessary) for
application to the then-existing Lender Indebtedness, any and all moneys,
dividends or other assets received in any such proceedings on account of the
Subordinated Indebtedness, unless and until the Lender Indebtedness has been
paid in full. If the Subordinated Creditor shall fail to take any such action,
the Lender, as attorney-in-fact for the Subordinated Creditor, may take such
action on the Subordinated Creditor's behalf. The Subordinated Creditor hereby
irrevocably appoints the Lender, or any of its officers or employees on behalf
of the Lender, as the attorney-in-fact for the Subordinated Creditor (which
appointment is coupled with an interest) with the power but not the duty to
demand, sue for, collect and receive any and all such moneys, dividends or other
assets and give acquittance therefor and to file any claim, proof of claim or
other instrument of similar character, to vote claims comprising Subordinated
Indebtedness to accept or reject any plan of partial or complete liquidation,
reorganization, arrangement, composition or extension and to take such other
action in the Lender's own name or in the name of the Subordinated Creditor as
the Lender may deem necessary or advisable for the enforcement of the agreements
contained herein; and the Subordinated Creditor will execute and deliver to the
Lender such other and further powers-of-attorney or instruments as the Lender
may request in order to accomplish the foregoing.

         9. Restrictive Legend; Transfer of Subordinated Indebtedness. The
Subordinated Creditor will cause the Subordinated Note and all other notes,
bonds, debentures or other instruments evidencing the Subordinated Indebtedness
or any part thereof to contain a specific statement thereon to the effect that
the indebtedness thereby evidenced is subject to the provisions of this
Agreement,



                                       -4-

<PAGE>   5




and the Subordinated Creditor will mark its books conspicuously to evidence the
subordination effected hereby. Attached hereto is a true and correct copy of the
Subordinated Note bearing such legend. At the request of the Lender, the
Subordinated Creditor shall deposit with the Lender the Subordinated Note and
all of the other notes, bonds, debentures or other instruments evidencing the
Subordinated Indebtedness, which notes, bonds, debentures or other instruments
may be held by the Lender so long as any Lender Indebtedness remains
outstanding. The Subordinated Creditor is the lawful holder of the Subordinated
Note and has not transferred any interest therein to any other person. Without
the prior written consent of the Lender, the Subordinated Creditor will not
assign, transfer or pledge to any other person any of the Subordinated
Indebtedness or agree to a discharge or forgiveness of the same so long as there
remains outstanding any of the Lender Indebtedness.

         10. Continuing Effect. This Agreement shall constitute a continuing
agreement of subordination, and the Lender may, without notice to or consent by
the Subordinated Creditor, modify any term of the Lender Indebtedness in
reliance upon this Agreement. Without limiting the generality of the foregoing,
the Lender may, at any time and from time to time, either before or after
receipt of any such notice of revocation, without the consent of or notice to
the Subordinated Creditor and without incurring responsibility to the
Subordinated Creditor or impairing or releasing any of the Lender's rights or
any of the Subordinated Creditor's obligations hereunder:

          (a) change the interest rate or change the amount of payment or extend
     the time for payment or renew or otherwise alter the terms of any Lender
     Indebtedness or any instrument evidencing the same in any manner;

          (b) sell, exchange, release or otherwise deal with any property at any
     time securing payment of the Lender Indebtedness or any part thereof;

          (c) release anyone liable in any manner for the payment or collection
     of the Lender Indebtedness or any part thereof,

          (d) exercise or refrain from exercising any right against the Borrower
     or any other person (including the Subordinated Creditor); and

          (e) apply any sums received by the Lender, by whomsoever paid and
     however realized, to the Lender Indebtedness in such manner as the Lender
     shall deem appropriate.

         11. No Commitment. None of the provisions of this Agreement shall be
deemed or construed to constitute or imply any commitment or obligation on the
part of the Lender to make any future loans or other extensions of credit or
financial accommodations to the Borrower.

         12. Notice. All notices and other communications hereunder shall be in
writing and shall be (i) personally delivered, (ii) transmitted by registered

conflict laws) of the State of Colorado. Each party consents to the personal
jurisdiction of the state and federal courts located in the State of Colorado in
connection with any controversy related to this Agreement, waives any argument
that venue in any such forum is not convenient, and agrees that any litigation
initiated by any of them in connection with this Agreement shall be venued in

exceeding the lesser of the Borrowing Base or $3,000,000.00. The Loans may be in

                           OCCUPANCY LICENSE AGREEMENT

     THIS OCCUPANCY LICENSE AGREEMENT ("Agreement") is made effective as of
October 1, 1998, by and between ADAPTEC, INC., a Delaware corporation
("Licensor"), and CHAPARRAL TECHNOLOGIES, INC., a Delaware corporation
("Licensee"), in the context of the following facts and circumstances:

     A. Licensor owns that certain building (the "Building") located at 1951
South Fordham Street, Longmont, Colorado 80503.

     B. Licensor and Licensee are desirous of entering into a short-term
occupancy arrangement for the use by Licensee of certain space within the
Building.

     NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties agree as follows:

     1. LICENSE AREA AND LOCATION. Licensor hereby grants to Licensee a
non-assignable, non-transferable right and revocable license for the use of that
certain area (the "License Area") containing approximately 19,823 rentable
square feet of space, located on the second floor of the Building approximately
as shown on the attached Exhibit A. (The rentable square feet is based upon a
18,021 square foot usable space plus a 1,802 square foot "load factor,"
representing ten percent of the usable square footage which is attributed to the
Common Facilities referenced in Paragraph 7 of this Agreement.) Licensee hereby
acknowledges and agrees that this right of use is a license only and not a
leasehold interest and that Licensee shall not be entitled to any actions,
claims, defenses, unlawful detainer protections, or other rights afforded to
lessees, tenants, or "parties in possession" under applicable law.

        Licensor may in its sole discretion, upon forty-five (45) days written
notice to Licensee, relocate the License Area to another location within the
Building; provided, however, that in such event Licensor will provide a
replacement area similar in size and type as the original License Area and will
provide improvements and furnishings to the relocated License Area similar in
type and scope of the Furnishings (defined below) provided by Licensor within
the License Area as originally located. In addition, in the event Licensor
requests that Licensee relocate, all reasonable costs of relocation, to be
mutually agreed upon by Licensor and Licensee, will be borne by Licensor.

     2. TERM. The term of this Agreement (the "License Term") will commence as
of the date Licensee first occupies the License Area pursuant to this Agreement
(the "Commencement Date"), and will continue for a period of nine (9) months
(the "Termination Date"), unless sooner terminated pursuant to the following
provisions:

        (a) Licensor may terminate this Agreement for cause by giving fourteen
(14) days written notice to Licensee. As used herein, "cause" means any of the
following: (i) Licensee is in material breach of a material obligation under
this Agreement, and Licensee has failed to correct such breach within fourteen
(14) days after written notice from Licensor; or (ii) Licensee causes or permits
hazardous materials or toxic substances to be used or handled in violation of
Paragraph 6 below; or



<PAGE>   2


(iii) the License Area is damaged or destroyed by a fire or other casualty that
makes it impracticable for Licensor to continue to allow Licensee to occupy the
License Area.

        (b) In the event that Licensor and Licensee enter into an enforceable
lease pursuant to Licensee's First Right of Negotiation (as set forth in
Paragraph 23), then this Agreement shall terminate as of the date that occupancy
commences under such lease.

        (c) In the event that Licensor sells the Building during the License
Term, then this Agreement shall terminate as of the date Licensor closes escrow
for such sale; provided, however, Licensor shall give Licensee notice of such
prospective sale at least three (3) months prior to the close of escrow.

        (d) In the event that there is a merger or acquisition of Licensee, at
Licensee's option, Licensee may terminate this agreement by giving Licensor at
least three (3) months prior written notice.

        On or before the Termination Date, Licensee shall completely remove all
of its personal property and vacate the License Area, leaving all of the
Furnishings therein in a clean and sanitary condition and in good working order.

     3. LICENSE FEE. For the use of the License Area, as well as for the use of
the Furnishings, the Common Facilities, and the Services provided by Licensor as
described below, Licensee shall pay to Licensor a fee (the "License Fee") in the
amount of $15.40 per rentable square foot per year, payable in monthly
installments in the amount of $25,439.52 due in advance on the first day of each
calendar month, in such manner and at such address as Licensor shall designate.
For any partial month at the beginning or end of the License Term, the monthly
License Fee will be prorated. A late charge of $400.00 will be assessed if the
License Fee is not paid by the 5th day of the month.

     4. PREPAID LICENSE FEE AND SECURITY DEPOSIT. Licensee shall pay to Licensor
upon execution of this Agreement the first month's License Fee, which amount
shall be held by Licensor and applied to the first installment due under this
Agreement. Licensee also shall pay to Licensor upon execution of this Agreement
an amount equal to one month's License Fee as a "Security Deposit", which amount
shall be held by Licensor as security for Licensee's faithful performance under
this Agreement. If Licensee fails to pay any License Fee or other amount due
under this Agreement, as and when due, or otherwise fails to perform its
obligations hereunder, then Licensor may, at its option and without prejudice to
any other remedy which Licensor may have, apply, use or retain all or any
portion of the Security Deposit toward the payment of delinquent amounts or for
any loss or damage sustained by Licensor due to such failure by Licensee.
Licensee shall upon demand restore the Security Deposit to the original sum
deposited. The Security Deposit shall not bear interest nor shall Licensor be
required to keep such sum separate from its general funds. To the extent not
otherwise applied by Licensor as provided herein, the Security Deposit shall be
returned to Licensee within thirty (30) days after the Termination Date.
Notwithstanding the foregoing, Licensor agrees to waive the requirement for
Licensee to pay said Security Deposit, provided that Licensee (i) does not fail
to pay any License Fee or other amount due under this Agreement, as and when
due, and (ii) does not otherwise breach a material obligation under this
Agreement. In the event

                                       -2-

of such failure or breach, Licensee shall be required to pay the Security
Deposit to Licensor within 10 days after written notice from Licensor.

Area or any of the Furnishings (including without limitation any painting, wall
hangings or signage), or add to, delete from or relocate any of the same,
without Licensor's prior written approval which may be withheld in Licensor's

the Building, or (v) use or allow the Building to be used for any improper,
immoral, unlawful or objectionable purpose. If, in the reasonable opinion of
Licensor, Licensee or Licensee's agents, employees, or invitees are engaging in
such conduct prohibited in, on or about the Building, Licensee, upon demand of
Licensor, shall enforce such restrictions and have such persons removed from the
Building. Licensor shall have the right but not

                                       -5-

<PAGE>   6


the obligation to remove or exclude from the Premises or the Building any person
engaging in such prohibited conduct.

         (g) Neither Licensor nor Licensor's agents, employees, or invitees
shall do, nor permit to be done, any of the following in, on or about the
Building: (i) solicit the employees of Licensee for employment, (ii) directly or
indirectly or by action in concert with others, induce or influence (or seek to
induce or influence) any person who is engaged (as an employee, agent,
independent contractor, or otherwise) by Licensee to terminate his or her
employment or engagement, (iii) use or allow the Building to be used for any
improper, immoral, unlawful or objectionable purpose.

     12. CONFIDENTIALITY. Licensee acknowledges that Licensee and other
licensees of the Building may be permitted by Licensor to utilize Licensor's
computer, telephone, message correspondence, and mail delivery facilities for
their operations, and Licensee agrees to use the utmost care to safeguard and
ensure that the confidential information, proprietary information, work product,
systems and files of Licensor, other licensees, or any other users or occupants
of the Building are not disclosed or misappropriated. Subject to the terms of
Paragraph 17 of this Agreement, Licensor shall use its best efforts to safeguard
and preserve the confidentiality of Licensee's work spaces, discussions, work
product, systems, files, and other proprietary information; provided, however,
Licensee acknowledges that if Licensee and other licensees of the Building
utilize Licensor's computer, telephone, message correspondence, and mail
delivery facilities for their operations, Licensor will have limited means to
protect the confidentiality of such confidential information, work product,
systems and files, and Licensee shall waive all claims for loss or damage to
Licensee or any person claiming by, through or under Licensee resulting from the
disclosure or misappropriation of Licensee's confidential information, work
product, systems or files, except to the extent caused by the gross negligence
or intentional misconduct of Licensor.

     13. LICENSOR'S RIGHT TO ENTER. Licensee agrees that Licensor shall have the
right to enter the License Area at all times for the purpose of inspecting the
same, making repairs, and performing its obligations under this Agreement.
Licensor shall use commercially reasonable efforts not to interfere with
Licensee's use of the License Area in connection with such entry.

     14. NO REPRESENTATIONS BY LICENSOR. Licensee hereby acknowledges and agrees
as follows:

         (a) Licensor has made no representations or warranties regarding the
level of safety and security in the Building, and Licensee will be responsible
for adequately protecting its own possessions, work product and files. However,
Licensee may request that Licensor make appropriate safety and/or security
modifications, which requests will not be unreasonably denied; provided,
however, that Licensee bears the entire cost of such modifications to the extent
that such modifications are outside of the Licensor's normal practices and
procedures.

         (b) Licensor has made no representations or warranties regarding the
condition of the License Area or the Common Facilities or the suitability
thereof for Licensee's purposes, and Licensee accepts the same in its "AS IS"
condition.

     15. REQUIRED INSURANCE. Licensee shall obtain, at its sole cost and
expense, and deliver to Licensor prior to the Commencement Date, signed
certificates of insurance evidencing currently effective policies of insurance
as follows:

         (a) Commercial general liability insurance with broad form contractual
liability coverage and with limits of not less than One Million Dollars
($1,000,000) combined each occurrence and in the aggregate insuring against any
and all liability of Licensee and/or Licensor (as an additional insured) with
respect to the License Area, or arising out of the maintenance, use or occupancy
thereof, or in connection with the conduct of Licensee's business within the
Building.

         (b) All Risk property insurance covering Licensee's personal property
and work product, in an amount not less than ninety percent (90%) of their full
replacement cost.

         (c) Workers' compensation insurance in such forms and amounts as is
required under the laws of the State in which the Building is located.

         Such certificates shall contain a provision that the policy of
insurance may not be canceled or reduced without prior notice to Licensor.

     16. INDEMNIFICATION OF LICENSOR. Licensee shall, at its sole cost and
expense, indemnify, protect, defend (with counsel acceptable to Licensor) and
hold harmless Licensor, its partners, shareholders, officers, directors,
attorneys, agents, beneficiaries, employees, affiliates, contractors, and
related entities (collectively, "Licensor's Related Parties") from and against
all liabilities, obligations, damages, penalties, claims, costs, charges and
expenses, including reasonable attorneys' fees, which may arise in any manner
out of or in connection with (i) Licensee's use of the License Area, the
Furnishings, the Services and/or the Common Facilities; (ii) the conduct of
Licensee's business; (iii) any act or omission of Licensee or Licensee's
partners, shareholders, officers, directors, attorneys, agents, beneficiaries,
employees, affiliates, contractors, and related entities (collectively,
"Licensee's Related Parties"); and/or (iv) any breach by Licensee under this
Agreement; provided, however, Licensee shall have no obligation to defend or
indemnify Licensor from claims which are caused by the sole negligence or
willful misconduct of Licensor or Licensor's Related Parties.

     17. WAIVER OF RESPONSIBILITY. Licensor and Licensor's Related Parties shall
not be liable for, and Licensee waives, all claims for loss or damage to
Licensee's business or damage or injury to person or property sustained by
Licensee or any person claiming by, through, or under Licensee, resulting from
any accident or occurrence in, on or about the License Area, or any other part
of the Building, including, without limitation, claims for loss, theft or damage
resulting from: (i) any Furnishings or other equipment or appurtenances being in
disrepair; (ii) injury done or occasioned by wind or weather; (iii) any defect
in or failure to operate, for whatever reason, any Furnishings or other
equipment or facilities in or about the Building; (iv) broken glass; (v) any
act, omission or negligence of other licensees, any other users or occupants of
the Building, any of Licensor's employees, or the public; or (vi) any other
cause of any nature. To the maximum extent permitted by law, Licensee agrees to
use and occupy the License Area, the Furnishings, the Services, and the Common
Facilities at Licensee's own risk.

     18. WAIVER OF RIGHT OF RECOVERY. Licensee (for itself and its insureds)
hereby releases and waives all right of recovery which it might otherwise have
(including rights of subrogation) against Licensor and Licensor's Related
Parties by reason of any loss or damage resulting from any recovery, claim,
action or cause for damages or injury or other occurrence no matter how caused,
to the extent that the same is covered by Licensee's insurance or which would
have been covered had Licensee complied with the requirements of Paragraph 15 of
this Agreement. The foregoing waiver shall be effective whether or not Licensee
maintains the insurance required to be carried pursuant to this Agreement.

         Licensor (for itself and its insureds) hereby releases and waives all
right of recovery which it might otherwise have (including rights of
subrogation) against Licensee and Licensee's Related Parties by reason of any
loss or damage resulting from any recovery, claim, action or cause for damages
or injury or other occurrence no matter how caused, to the extent that the same
is covered by Licensor's insurance.

     19. HOLDING OVER. If Licensee fails to vacate the License Area upon
termination of this Agreement, Licensee's presence upon or occupancy of the
License Area shall constitute a trespass. Licensor shall have the benefit of all
provisions of law respecting the recovery of the License Area and removal of
Licensee and its employees, including but not limited to, changing the locks to
the Building and/or the License Area, requesting action by local law enforcement
officers, and/or immediate injunctive relief. Licensee's occupancy of the
License Area subsequent to the termination of this Agreement shall be subject to
all the terms, covenants, and conditions of this Agreement for Licensor's
benefit, except that the License Fee shall be three times the License Fee
otherwise payable hereunder. After termination of this Agreement, Licensor shall
have no obligation to provide or allow Licensee to use any Furnishings,
Services, or Common Facilities.

     20. DEFAULT. Each party may exercise any remedy available to it at law or
in equity upon the other party's breach or default of this Agreement, and the
rights, remedies, and benefits provided by this Agreement and by law are
cumulative and nonexclusive. In the event of any action or other proceeding to
interpret or enforce this Agreement, the prevailing party shall be entitled to
recover its reasonable attorney's fees from the other party.

     21. MISCELLANEOUS PROVISIONS. This Agreement may be modified only in
writing by Licensor and Licensee. This Agreement is the only agreement between
the parties with respect to the subject matter of this Agreement, and all other
negotiations, representations and agreements between the parties are merged
therein. This Agreement shall be governed by the laws of the State in which the
Building is located. This Agreement shall not be strictly construed against the
party preparing it, but shall be construed as if all parties prepared this
Agreement jointly upon the advice of their respective legal counsel. If any
provision in this Agreement is held by any court to be invalid, void or
unenforceable, the remaining provisions shall nevertheless continue in full
force and effect. Waiver by Licensor of any breach of any term, covenant or
condition herein contained shall not be deemed a waiver of any subsequent breach
of the same or any other term, covenant or condition herein contained. Time is
of the essence of this Agreement and of every term, covenant and condition
hereof.

     22. DELIVERY BY COUNTERPARTS AND FACSIMILES. This Agreement may be executed
in two or more counterparts, each of which shall be deemed an original and which
together shall constitute one and the same instrument. Each party may execute
and deliver this instrument by facsimile, and facsimiles of signatures shall be
deemed original signatures for all purposes, but each party executing and
delivering this instrument by facsimile shall also send the other party an
original of this instrument containing such party's ink signature. Each person
executing this Agreement represents that the execution of this Agreement has
been duly authorized by the party on whose behalf the person is executing this
Agreement.

     23. FIRST RIGHT OF NEGOTIATION. If at any time during the License Term,
Licensor desires to lease the additional space located on second floor of the
Building (the "Lease Space"), to a party other than an Affiliate (defined
below), then Licensor shall give Licensee written notice ("Lease Notice") of
such intention. Licensee shall have the first right, by giving written notice to
Licensor within five (5) business days after receipt of Licensor's Lease Notice,
to negotiate with Licensor for the lease of the Lease Space. If, within thirty
(30) days after the date of Licensor's Lease Notice, the parties do not enter
into a written lease agreement for the Lease Space, then Licensor shall be
entitled to negotiate for the lease of the Lease Space with any other party and
enter into any agreements with respect thereto, and this first right of
negotiation shall be void and of no further force or effect.

         For purposes of this Agreement, an "Affiliate" shall mean any
corporation or entity with which Licensor may merge or consolidate or become
affiliated as a parent, subsidiary, holding company or otherwise, or any
corporation or entity with which Licensor has a strategic business relationship.

     24. CROSS DEFAULT. Any failure by Licensee to observe or perform any term,
covenant, or condition of the Occupancy License Agreement dated November 25,
1998, entered into by and between Licensor and Licensee with respect to that
certain building located at 9701 Jeronimo Road, Irvine, California 92618 and the
license area consisting of approximately 1,000 rentable square feet of space
within such building, shall constitute a material breach of a material
obligation by Licensee under the terms of this Agreement. Licensor and Licensee
acknowledge and agree that the dispute resolution procedure set forth in the
Asset Transfer Agreement between ADAPTEC, INC. and CHAPARRAL TECHNOLOGIES, INC.
dated November 25, 1998 shall be implemented with respect to any failure under
this Paragraph.

                           OCCUPANCY LICENSE AGREEMENT

     THIS FIRST AMENDMENT TO OCCUPANCY LICENSE AGREEMENT ("Amendment") is made
effective as of July 15, 1999, by and between ADAPTEC, INC., a Delaware
corporation ("Licensor"), and CHAPARRAL NETWORK STORAGE, INC., formerly known as
Chaparral Technologies, Inc., a Delaware corporation ("Licensee"), in the
context of the following facts and circumstances:

     A. Pursuant to that certain Occupancy License Agreement (the "OLA") between
the parties effective as of October 1, 1998, Licensor granted to Licensee the
right to occupy certain premises (the "License Area") within a building owned by
Licensor (the "Building") located at 1951 South Fordham Street, Longmont,
Colorado 80503.

     B. The term of the OLA expired on June 30, 1999. Since that time Licensee
has been occupying the License Area on the basis of an oral agreement to extend
the OLA on a month-to-month basis. Licensor and Licensee are desirous of
formalizing such agreement in accordance with the terms and conditions set forth
in this Amendment.

     NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties agree that the OLA is hereby amended
as follows:

     1. TERM. The term of the OLA is extended on a month-to-month basis
commencing effective as of July 1, 1999, on all of the terms and conditions of
the OLA, except as follows:

        (a) Licensor and/or Licensee shall continue to have each of their
respective rights to terminate the OLA as and when provided by Paragraphs 2(a)
through 2(d) of the OLA; provided, however, that notwithstanding anything to the
contrary contained in the OLA, either Licensor or Licensee may terminate the OLA
at any time, for any reason, by giving at least thirty (30) days' written notice
of termination to the other party.

        (b) Any Services provided by Licensor to Licensee, as defined in
Paragraph 8 of the OLA, can be deleted or changed by Licensor, upon giving at
least thirty (30) days' written notice to Licensee. Licensor shall include in
its notice a statement describing Licensor's reasonable determination of any
adjustment to the License Fee that will be made based on such deletion or change
in Services.

        (c) Paragraph 23 of the OLA (regarding Licensee's First Right of
Negotiation) no longer applies and is hereby deleted.

        (d) Paragraph 24 of the OLA (regarding Cross Default) is hereby amended
to delete the reference to the space located at 9701 Jeronimo Road, Irvine,
California 92618, and to substitute therefor the space located at 27121 Towne
Centre Drive, Foothill Ranch, California 92610.

     2. RATIFICATION OF OLA. Except as specifically provided in this Amendment,
all terms and conditions of the OLA shall remain unchanged and in full force and
effect, and are hereby ratified by the parties.

     3. BINDING EFFECT. This Amendment shall be binding on both parties only
when both parties shall have executed this document and delivered the same to
each other.

     4. DELIVERY BY COUNTERPARTS AND FACSIMILES. This Amendment may be executed
in two or more counterparts, each of which shall be deemed an original and which
together shall constitute one and the same instrument. Each party may execute
and deliver this instrument by facsimile, and facsimiles of signatures shall be
deemed original signatures for all purposes, but each party executing and
delivering this instrument by facsimile shall also send the other party an
original of this instrument containing such party's ink signature. Each person
executing this Agreement represents that the execution of this Agreement has
been duly authorized by the party on whose behalf the person is executing this
Agreement.

                                      LEASE

THIS LEASE made this 1st day of September, 1999, between Chaparral Network
Storage, Inc., a Delaware Corporation ("Tenant"), and BTC Development, LLC
"Landlord").

                                   WITNESSETH:

                                     DEMISE

         Landlord does hereby lease to Tenant and Tenant hereby leases from
Landlord an approximate 20,000 rentable square feet (the "Premises," or,
alternatively, the "Leased Premises") Dry Creek Corporate Center (the
"Building"), which Building is situated on land described as 7040 East Dry Creek
Parkway, Longmont, Colorado 80503 (the "Property"), together with a
non-exclusive right, subject to the provisions of this Lease, to use all
appurtenances thereto, including, but not limited to, any plazas, common areas,
parking lots, walks, ways or other areas in the Building or on the Property
designated by Landlord for the exclusive or non-exclusive use of the tenants of
the Building.

         The Lease is upon and subject to the terms, conditions, and covenants
set forth below and Tenant covenants as a material part of the consideration for
this Lease to keep and perform each and all of the terms, conditions, and
covenants by it to be kept and performed and that this Lease is made upon the
condition of such performance.

                                    SECTION 1
                                     PURPOSE

         1.1 Use of Premises. The Premises are to be used for office,
engineering labs, product development, shipping, receiving, warehousing and
manufacturing and related office functions, provided that such uses comply with
all zoning and use restrictions, and for no other purpose without the prior
written consent of Landlord.

                                    SECTION 2
                                      TERM

         2.1 Primary Term. The Term of this Lease shall be for a period of sixty
(60) months. Lease commencement, (Commencement Date) will then take place on
March 15, 2000, and on March 31, 2005 ("The Primary Lease Term"). The Primary
Lease Term will commence upon receipt of a Certificate of Occupancy for the
Premises.

                  (a) Should Tenant, through the actions of Tenant, it's
employees, agents, contractors, subcontractors, guests, licensees, or invitees,
impede, delay or in some manner alter the aforementioned schedule for buildout,
thus causing the estimated occupancy date to move to a future date, then the
Primary Lease Term will commence on the estimated date specified in Section 2 of
herein lease, even though a Certificate of Occupancy has not been received from
the Building Department of the Boulder County.

                                    SECTION 3
                           COMPLETION OF THE PREMISES

         (See Space Plan. Addendum "A") Tenant shall have a Build Out Allowance
of $440,000.00 or $22.00 per useable square foot. The Build Out Allowance
includes all costs incurred in designing, permitting, construction, and
installation of Tenant Improvements. All costs in excess of allowance are to be
paid by Tenant. Golden Triangle Construction (GTC) will be the General
Contractor for any initial Tenant Improvement work done to the Premises. GTC
will generally request 3 competitive bids for all subcontract work to be
performed, and will provide to Tenant a breakdown of all costs prior to the
commencement of any work. All costs in excess of Build Out Allowance will be
added to Lease Rate and amortized at ten percent (10%) over the term of the
Lease.

                                    SECTION 4
                                      RENT

         4.1 Base Rent. Tenant agrees to pay Landlord during the full Primary
Lease Term the sum of $1,144,458.33, payable in advance in equal monthly
installments of $18,916.66 for the Premises: The first full monthly installment
of Base Rent shall be payable on the Commencement Date and each succeeding
monthly installment shall be due and payable on or before the first day of each
and every successive calendar month thereafter during the Primary Lease Term.
The exact square footage of the Premises will be measured "as-built" and Rent
adjusted accordingly.

         4.2 No Offsets. The Base Rent and all other sums or changes required by
this Lease to be paid by Tenant to Landlord, (all of which are sometimes
collectively referred to as "Rent") shall be paid to Landlord without deduction
or offset, in lawful money of the United States of America, at the office of
O'Connor Development, LLC, 287 Century Circle, Suite 101, Louisville, Colorado
80027 or to such other person or at such other place as Landlord may from time
to time designate in writing.

         4.3 Interest on Late Payments. Any Rent or other amount due from Tenant
to Landlord under this Lease not paid within seven (7) days of when due shall
bear interest from the date due, computed on a daily basis, until the date paid,
at the rate of four percent (4%) over the "Prime Rate" per month, as announced
by Norwest Bank of Colorado, NA from time to time, but the payment of the
interest shall not excuse nor cure any default by Tenant under this Lease.

         4.4 Late Payment Charge. Further, and notwithstanding the interest
charges provided for in the preceding Subsection 4.3, if any Rent or other
amounts owing hereunder are not paid within seven (7) days of when due, Landlord
and Tenant agree that Landlord will incur additional administrative and
financial expenses and inconveniences, the amount of which will be difficult if
not impossible to determine. Accordingly, Tenant shall pay to Landlord an
additional one-time late charge for any late monthly payment in the amount of
$500.00.

         4.5 Inflation Index. The Base Rent shall be further increased annually
on each March 15 commencing on March 15, 2001, by an amount determined as
follows:

                  (a) As promptly as practical after January of every year
beginning January 2001, Landlord shall compute the increase, if any, in the cost
of living for the preceding calendar year, based upon the "All Items and Major
Group Figures for Urban Wage Earners and Clerical Workers, Denver, Colorado" all
items, as published by the Bureau of Labor Statistics United States Department
of Labor, based on all items for the period (1982-84 = 100). This Consumer Price
Index shall hereinafter be referred to as the "Index Figure."

                  (b) The Index Figure indicated in the column for All Cities
entitled "all items," for the month of January shall be the "Base Index Figure,"
and the corresponding Index Figure for the month of January for every year
thereafter shall be the "Current Index Figure."

                  (c) The Current Index Figure shall be divided by the Base
Index Figure and the resulting product, if greater than one, shall be multiplied
times the previous year's Base Rent to obtain the new increased Base Rent. If
the resulting product is equal to one or less than one, the new year's Base Rent
shall be the previous year's Base Rent.

                  (d) Landlord shall, within a reasonable time after obtaining
appropriate data necessary for computing the increase, give Tenant notice of the
increase so determined, which notification shall include computation of the
amount due to Landlord by Tenant.

                  (e) If publication of the Consumer Price Index for All Urban
Consumers shall be discontinued, the parties shall accept a comparable index
published by a reliable government agency which measures the purchasing power of
the consumer dollar.

         4.6 Payment of Rent Increase. All determinations by Landlord pursuant
to Section 4.5 shall be conclusive, unless in error. Until Tenant is advised of
the adjustments in the Base Rent, if any, pursuant to the provisions of this
paragraph 4.6, Tenant's monthly Base Rent shall continue to be paid at the then
current rate (including all prior rental adjustments). Tenant shall commence
payment to Landlord of the monthly installment of Base Rent on the basis of the
adjustments so determined beginning on the first day of the month following the
month in which Landlord advises Tenant of the increased Base Rent. In addition,
Tenant shall pay to Landlord on the date required for the first payment of Base
Rent as adjusted, the difference, if any, between the monthly installment of
Base Rent so adjusted and the monthly installments of Base Rent actually paid
during the Base Rent period to make up for the increased Base Rent between the
first month that a rental Increase is due and the first payment after notice of
the increase, provided that Landlord notifies Tenant of Rental Rate Adjustment
within forty-five (45) days of effective date of said rental rate adjustment.
Notwithstanding any other provisions of the Lease, if this Lease is terminated
prior to the end of the calendar year, for any reason, Tenant's obligations to
pay rental adjustments for that portion of any calendar year which has elapsed
prior to termination shall survive the termination of the Lease, whether by
expiration or otherwise.

                                    SECTION 5
                   TAXES AND OPERATING COST ADJUSTMENT FORMULA

         5.1 Additional Rent. In addition to Base Rent, Tenant shall reimburse
Landlord for the Taxes and Operating Costs of the Building in the manner, at the
times, and in the amounts set forth in this Section 5.

         5.2 (a) Taxes. The Rent payable by Tenant shall be increased by the
amount of "Tenant's Proportional Share" of the Taxes on the Property. Tenant's
Proportional Share shall be 34% based upon Tenant's initial occupancy of 20,000
square feet out of a total building rental space of 60,000 square feet. Tenant's
Proportional Share shall be subject to confirmation and/or adjustment based on
"as-built" measurements of the Premises and Building. In determining the amount
of Taxes for any calendar year, the amount of special assessments to be included
shall be limited to the amount of the installment (plus any interest payable
thereon) of such special assessment which would have been required to have been
paid during such calendar year if Landlord had elected to have the special
assessment paid over the maximum period of time permitted by law, if the
election is available to Landlord. All reference to Taxes "for" and "billed for"
a particular calendar year shall be deemed to refer to Taxes levied, assessed,
billed or otherwise imposed for such calendar year, without regard to the dates
when any such Taxes are due and payable.

             (b) Definition. As used in this Lease, the term "Taxes" means any
and all general and special taxes and impositions of every kind and nature
whatsoever levied, assessed, or imposed upon, or with respect to, the Premises,
any leasehold improvements, fixtures, installations, additions and equipment,
whether owned by Landlord or Tenant, or either because of or in connection with
Landlord's ownership, leasing and operation of the Building and the Property,
including, without limitation, real estate taxes, personal property taxes,
general or special assessments, and duties or levies charged or levied upon or
assessed against the Building and the Property and personal property, or any
other tax (however described) on account of rental received for use and
occupancy of any or all of the Building and the Property, whether any such taxes
are imposed by the United States, the State of Colorado, the County of Boulder,
or any local governmental municipality, authority, or agency or any political
subdivision. Taxes shall not include any net income, capital stock, succession,
transfer, franchise, gift, estate or inheritance taxes.

             (c) Payment. Commencing with the first calendar month of this
Lease, Tenant shall pay to Landlord on the first day of each calendar month
until the next upward adjustment date (which period between adjustment dates is
herein called a "Tax Deposit Year") one-twelfth of Tenant's Proportional Share
of the estimated amount of the Taxes. Amounts paid under this Subsection 5.2(c)
in any Tax Deposit Year shall be reconciled with amounts actually billed to
Landlord for the same Tax Deposit Year, and provided there is any surplus
remaining after the credit to Tenant and provided Tenant shall not then be in
default under any of the provisions of this Lease, Landlord shall, at Landlord's
option, either refund the amount of the surplus to Tenant within thirty (30)
days following the end of the Tax Deposit Year or apply the surplus amount
against any other amounts then due from Tenant to Landlord, including Rent. If
upon the


                                       -4-

<PAGE>   8



reconciliation there is any deficiency in the amount of Taxes paid by Tenant,
Landlord shall bill Tenant and Tenant shall pay the additional amount within
thirty (30) days following Tenant's receipt of Landlord's reconciliation report.

         5.3 (a) Inclusion in Operating Costs. Tenant shall pay its Proportional
Share of the Operating Costs for the Property. As used in this Lease, the term
"Operating Costs" means any and all expenses, costs and disbursements (other
than Taxes and other than the exclusion described in Section (b) below) of every
kind and nature whatsoever, which are paid or accrued by Landlord in connection
with the management, maintenance, operation or repair of the Building,
including, without limitation, not to exceed $2.40 per square foot in the first
full year of operation:

                           (i) Costs of supplies;

                           (ii) Costs incurred in connection with obtaining and
providing energy for the Building, including, but not limited to, costs of
propane, butane, natural gas, steam, electricity, fuel oils, coal or any other
energy sources, except if separately metered to the Leased Premises, in which
case Tenant shall pay 100% of its metered amount and it's portion of any common
metered utility;

                           (iii) Costs of water and sanitary sewer and storm

                           (v) Cost of insurance;

                           (vi) Costs of maintenance and replacement of
landscaping;

                           (vii) Labor costs associated with operation,
maintenance, and management of the Building; and management fees.

             (b) Exclusion from Operating Costs. "Operating Costs" shall not
include:

                           (i) Insurance deductibles and the costs of repairs or
other work occasioned by fire, windstorm or other insured casualty to the extent
of insurance proceeds received;

                           (ii) Leasing commissions, advertising, advertising
expenses, Tenant finish allowances and other costs incurred in leasing space in
the Building;

                           (iii) Costs of repairs or building necessitated by
condemnation or necessitated by faulty or substandard initial construction;


                                       -5-

<PAGE>   9

                           (iv) Any interest on borrowed money or debt
amortization, except as specifically set forth above;

                           (v) Depreciation on the Building;

                           (vi) Any settlement, payment or judgment incurred by
Landlord or the Building manager due to their willful misconduct or gross
negligence;

                           (vii) Cost of any damage to the Building caused
directly by Landlord's willful misconduct or gross negligence, as established by
a court of law, whether or not covered by insurance;

                           (viii) Cost of capital improvements (as defined under
the Internal Revenue Code) and structural repairs or reconstruction of any
portion of the Building;

                           (ix) Costs of providing utility lines to the Building
or repairing such lines if they break (but not if they are plugged by Tenant's
usage).

                  (c) Warranties. Tenant shall be entitled to reimbursement for
any amounts collected by Landlord under any manufacturer's warranty on any
systems or machinery used in the Building; provided that Tenant has previously
paid to Landlord the repair expense relating to Landlord's warranty claim.

                  (d) Payment. Beginning on the Commencement Date, Landlord
shall supply Tenant with written notice of Landlord's estimate of the Operating
Expenses that will be incurred or accrued during the current calendar year (the
"Deposit Year"). On or before the first day of each month during such Deposit
Year, Tenant shall pay to Landlord one-twelfth of Tenant's Proportional Share of
the estimated amount. If the monthly deposit amount is not determined in time
for Tenant to make the first payment on January 1 of the Deposit Year, then the
first monthly payment shall be due on the first day of the month immediately
following the date Landlord supplies Tenant with notice of the amount and the
first monthly payment(s) shall also include a payment equal to one-twelfth of
such additional sum multiplied by the number of calendar months which have
elapsed during the Deposit Year prior to the date Tenant makes its first
payment. If the total of the estimated payments made by Tenant during the
Deposit Year are less than Tenant's obligation under this Lease for Operating
Costs for the Deposit Year, then Tenant, within thirty (30) days of the billing
therefor, shall pay the deficiency to Landlord. If the total of the Tenant's
estimated payments for the Deposit Year exceed Tenant's obligation for excess
Operating Costs for such year, then the surplus shall be handled in the manner
provided in the second to last sentence of Section 5.2(c).

         5.4 Audit and Adjustment Procedures.

                  (a) The annual determination and statement of Taxes and
Operating Costs shall be prepared in accordance with generally accepted
accounting principles. In the event of any dispute as to any Rent due under this
Lease, Tenant shall have the right to inspect Landlord's


                                       -6-

<PAGE>   10


accounting records relative to Taxes and Operating Costs at the office in which
Landlord maintains its records during normal business hours at any time
following the furnishing by Landlord to Tenant of the statement. Any errors
shall be adjusted accordingly.

                  (b) If the Term of this Lease commences on any day other than
the first day of the month, or if the Term of this Lease ends on any day other
than the last day of the month, any payment due to Landlord by reason of an
increase in Taxes or Operating Costs shall be prorated on the basis by which the
number of days in such partial year bears to 365.

                  (c) All sums which Tenant is required to pay or discharge
pursuant to Section 5 of this Lease in addition to Base Rent, together with any
interest or other sums which may be added for late payment, shall constitute
"Rent".

                                    SECTION 6
                                  HOLDING OVER

         6.1 Rent Increase. Should Tenant hold over after the termination of
this Lease, on account of a Tenant Event of Default which is not timely cured,
or if Tenant holds over at the expiration of this Lease for more than
one-hundred twenty (120) days after receipt of Landlord's written notice to
vacate, Tenant shall become a tenant from day-to-day upon each and all of the
terms herein provided as may be applicable to such a tenancy, and any such
tenancy shall not constitute an extension of this Lease; provided, however,
during the period as a tenant from day-to-day, Tenant shall pay Base Rent at
125% the rate payable for the month immediately preceding the date of
termination of this Lease and, in addition, Tenant shall reimburse Landlord for
all damages (consequential, as well as direct) sustained by it by reason of
Tenant's occupying the Premises past the termination date. Alternatively, unless
Landlord has provided Tenant with a notice to vacate not less than one-hundred
twenty (120) days prior to the expiration of this Lease, the retention of
possession past the termination date shall constitute a month-to-month tenancy
upon each and all of the terms of this lease as may be applicable to a
month-to-month tenancy except that Tenant shall be entitled to a one-hundred
twenty (120) day notice period prior to being required to vacate the Premises.

                                    SECTION 7
                                BUILDING SERVICES

         7.1 Interruption of Standard Services. Tenant agrees that Landlord
shall not be liable for failure to supply any heating, air conditioning,
janitorial services, electric current, or any other utility during any period
when Landlord uses reasonable diligence to restore or to supply such services or
utility. Landlord reserves the right to temporarily discontinue such services at
times as may be necessary by reason of accident, repairs, alterations, or
improvements, or whatever by reason of strikes, lockouts, riots, acts of God, or
any other happening or occurrence beyond the reasonable control of Landlord,
provided such discontinuance does not substantially interfere with Tenant's
business operations.


                                       -7-

<PAGE>   11


         7.2 Telephone. Tenant shall separately arrange with the applicable
local public authorities or utilities, as the case may be, for the furnishing of
and payment for all telephone services as may be required by Tenant in the use
of the Premises. Tenant shall directly pay for such telephone services,
including the establishment and connection thereof, at the rates charged for the
services by the authority or utility, and the failure of Tenant to obtain or to
continue to receive the services for any reason whatsoever shall not relieve
Tenant of any of its obligations under this Lease. Landlord shall supply
sufficient telephone lines into the Building for Tenant's connection.

         7.3 Above-Standard Service Requirements. Landlord's original design
shall include HVAC equipment adequately sized for Tenant's needs. If Tenant
thereafter adds heat-generating machines or any equipment which cause the
temperature in the Premises, or any part, to exceed the temperatures that the
Building's air conditioning and other cooling systems would be able to maintain
in the Premises were it not for the heat-generating equipment then Landlord
reserves the right to install supplementary air conditioning units in the
Premises, and the cost, including the cost of installation and the cost of
operation and maintenance thereof, shall be paid by Tenant to Landlord upon
demand by Landlord. If Tenant requires electric current, water, or any other
energy in excess of that which is reasonably obtainable from existing electrical
outlets or water pipes, and which is, in Landlord's opinion, above normal for
use of the Premises, Tenant shall first procure the consent of Landlord, which
Landlord may not unreasonably refuse. If Landlord consents to such excess
electric, water, or other energy requirements, Tenant shall, on demand, pay all
costs of meter service and installation of facilities necessary to measure
and/or furnish such excess capacity. Tenant shall also pay the entire cost of
such additional electricity, water, or other energy used.

                                    SECTION 8
                              CONDITION OF PREMISES

         8.1 Acceptance Upon Possession. Tenant, by taking possession of the
Premises, shall be deemed to have agreed that the Premises were, as of the date
of taking possession, in good order, repair, and condition and satisfactorily
completed in accordance with Landlord's obligations under this Lease. No promise
of Landlord to alter, remodel, decorate, clean or improve the Premises, the
Building, or the Property and no representation or warranty, express or implied,
respecting the condition of the Premises, the Building, or the Property has been
made by Landlord to Tenant, unless the same is contained in this Lease, the Work
Agreement, the Plans or some other written agreement. This Lease does not grant
any rights to light or air over the Premises or the Property. Landlord warrants
that the Premises will be delivered to Tenant in good and workmanlike condition,
free from defects for a period of one (1) year at Landlord's sole cost and
expense (and not as an operating cost past through).

                                    SECTION 9
                             USE OF LEASED PREMISES

         9.1 Use. The Leased Premises shall not be used other than for the
purpose set forth in Section 1 of this Lease. Tenant's use shall at all times
comply with all applicable laws, ordinances, regulations, or other governmental
ordinances in existence.

         9.2 Hazardous Use. Tenant agrees that it will not keep, use, sell or
offer for sale in or upon the Leased Premises any article which may be
prohibited by any insurance policy in force from time to time covering the
Building. In the event Tenant's occupancy or conduct of business in or on the
Leased Premises, whether or not Landlord has consented to the same, results in
any increase in premiums for the insurance carried from time to time by Landlord
with respect to the Building, Tenant shall pay any such increase in premiums as
Rent within ten (10) days after bills for such additional premiums shall be
rendered by Landlord. Tenant shall promptly comply with all reasonable
requirements of the insurance authority or of any insurer now or hereafter in
effect relating to the Leased Premises.

         9.3 No Waste. Tenant shall not commit, suffer, nor permit any waste,
damage, disfiguration, or injury to the Leased Premises or the Building's common
areas or the fixtures and equipment located in or on the Building, or permit or
suffer any overloading of the floors and shall not place any safes, heavy
business machinery, or other heavy things in the Premises other than as
specifically provided for in the Work Agreement and Plans, without first
obtaining the written consent of Landlord and, if required by Landlord, of
Landlord's architect, and shall not use or permit to be used by any part of the
Leased Premises for any dangerous, noxious, or offensive trade or business, and
shall not cause or permit any nuisance, noise, or action in, at, or on the
Leased Premises. Landlord shall not withhold its consent to Tenant's
installation of additional machinery and equipment as long as Tenant agrees to
make any modifications to the Premises which are necessary for the safe
installation and operation of said equipment or machinery.

         9.4 Protection Against Insurance Cancellation. If any insurance policy
on the Building or any part thereof shall be canceled or if cancellation shall
be threatened, or if the coverage shall be reduced or be threatened to be
reduced, in any way by reason of the use of occupation of the Leased Premises or
any part thereof by Tenant, any assignee or subtenant of Tenant, or by anyone
permitted by Tenant to be upon the Leased Premises, and if Tenant fails to take
reasonable efforts to remedy the condition giving rise to the cancellation,
threatened cancellation, reduction, or threatened reduction of coverage within
forty-eight (48) hours after written notice or to complete the remedy within ten
(10) days after notice, Landlord may, at its option, enter upon the Leased
Premises and attempt to remedy the condition, and Tenant shall forthwith pay the
cost to Landlord as additional Rent. Landlord shall not be liable for any damage
or injury caused to any property of Tenant or of others located on the Leased
Premises as a result of such entry unless such damage or injury is a result of
Landlord's gross negligence.

                                   SECTION 10
                               COMPLIANCE WITH LAW

         10.1 Compliance. Tenant shall not use the Premises or permit anything
to be done in or about the Premises which will in any way conflict with any law,
statute, ordinance, or governmental rule or regulation now in force or which may
hereafter be enacted or promulgated. Tenant shall, at its sole cost and expense,
promptly comply with all laws, statutes, ordinances, and governmental rules,
regulations, or requirements now in force or which may hereafter be in force,
and with the requirements of any board of fire underwriters or other similar
body now or hereafter constituted relating to or affecting the condition, use,
or occupancy of the Premises, excluding structural changes not related to or
affected by Tenant's improvements or acts.

                                   SECTION 11
                             ALTERATIONS AND REPAIRS

         11.1 Tenant to Maintain. Tenant shall, at its sole expense, keep the
Premises in good repair and tenantable condition during the Term of this Lease,
provided, however, that the Landlord warrants that the Premises shall be
delivered to Tenant in good and workmanlike condition, free from defects for the
first year of the Lease Term, at Landlord's sole cost and expense. Tenant shall
not, without the prior written consent of the Landlord, whose consent shall not
be unreasonably withheld so long as Tenant demonstrates financial assurance of
its ability to restore the Premises to original condition, make any alterations,
improvements, or additions to the Premises in excess of $25,000.00 per project,
including, but not limited to, partitions, wall coverings, floor coverings, and
special lighting or equipment installations. Prior to commencement of any
alterations, improvements, or additions, Tenant shall submit to Landlord a set
of fully detailed working drawings and specifications for the proposed
alteration, prepared by a licensed architect, or engineer, approved by the
Landlord. In particular, but not as a limitation, the working drawings must
fully detail changes to mechanical, wiring, electrical, lighting, plumbing, and
HVAC systems to landlord's satisfaction. Landlord may refuse to consent to the
alterations because of the inadequacy of the drawings and specifications. All
alterations, improvements, or additions, whether temporary or permanent in
character, made by Landlord or Tenant in or upon the Premises shall become
Landlord's property and shall remain upon the Premises at the termination of
this Lease by lapse of time or otherwise, without compensation to Tenant
(excepting only Tenant's movable office furniture, trade fixtures, manufacturing
equipment and machinery and office and professional equipment or other personal
property). Tenant shall promptly pay to Tenant's contractors, when due, the cost
of all work and of all decorating, and upon completion, deliver to Landlord, if
payment is made directly to Tenant's contractors, evidence of payment and
waivers of all liens for labor, services, or materials. Tenant shall defend and
hold Landlord, the Premises, the Building, and the Property harmless from all
costs, damages, liens for labor, services, or materials relating to the work,
and shall defend and hold Landlord harmless from all costs, damages, liens, and
expenses related to the work. If Landlord incurs any expenses in the removal of
trash or cleaning as a result of Tenant's contractor's work, then Tenant agrees
it shall reimburse Landlord within seven (7) days of billing.


                                      -10-

<PAGE>   14


         11.2 Protection Against Liens. At least five (5) days prior to the
commencement of any work on the Leased Premises in excess of $25,000.00, Tenant
shall notify Landlord of the names and addresses of the persons supplying labor
and materials for the proposed work so that Landlord may avail itself of the
provisions of statutes such as Section 38-22-105(2) of the Colorado Revised
Statutes (1973), or any successor statutory provision. During the progress of
any work on the Leased Premises, Landlord or its representatives shall have the
right to post and keep posted thereon notices such as those provided for by
Sections 38-22-105(2) (C.R.S. 1973) or to take any further action which Landlord
may deem to be proper for the protection of Landlord's interest in the Leased
Premises.

         11.3 Condition on Surrender. Tenant shall, at the termination of this
Lease, surrender the Premises to Landlord in as good condition and repair as
reasonable and proper use will permit, loss by ordinary wear and tear, fire, and
other insured against casualty excepted.

         11.4 Damage by Tenant. If any part of the Building or other
improvements become damaged or are destroyed through the negligence,
carelessness, or misuse of Tenant, its servants, agents, employees, or anyone
permitted by Tenant to be in the Building, or through Tenant or such parties,
which damage is not covered by applicable policies of insurance, then the cost
of necessary repairs, replacements, or alterations shall be borne by Tenant, who
shall, on demand, forthwith pay the same to Landlord as Rent.

                                   SECTION 12
                                   ABANDONMENT

         12.1 Disposition of Personal Property. Tenant shall not vacate or
abandon the Premises at any time during the Lease Term, and if Tenant shall
abandon, vacate, or surrender (whether at the end of the stated Term or
otherwise) the Premises, or shall be dispossessed by process of law or otherwise
and Tenant shall thereafter cease paying its Rent, then any personal property
belonging to Tenant left on the Premises shall be deemed abandoned and may be
sold or otherwise disposed of by Landlord without any liability to Tenant
whatsoever. Tenant shall not at any time remove Landlord's property or any
fixtures constituting property of Landlord from the Premises. Any removal of
Landlord's property from the Premises by Tenant shall constitute a material
breach of this Lease and Landlord shall have the right to take all reasonable
steps to stop or prevent such breach without such actions constituting a
constructive eviction of Tenant.

                                   SECTION 13
                            ASSIGNMENT AND SUBLETTING

         13.1 Limitation on Assignment or Subletting. Tenant shall not assign
this Lease, or any interest therein, and shall not sublet the Premises, or any
part thereof, or any right or privilege appurtenant thereto, or shall not suffer
any other person to occupy or use the Premises, or any portion thereof, without
the written consent of Landlord, which consent may not be unreasonably withheld.
Neither this Lease nor any interest therein shall be assignable as to the
interest of Tenant by operation of law without the written consent of Landlord,
which consent may not be unreasonably withheld.


                                      -11-

<PAGE>   15


         13.2 Acceptance of Performance; No Waiver. If this Lease is assigned,
or if the Premises or any part are sublet or occupied by anybody other than
Tenant, Landlord may, upon default by Tenant, collect the rent from the
assignee, subtenant, or occupant and apply the net amount collected to the Rent.
Upon assignment pursuant to the terms of this section, Tenant shall be relieved
of further liability under this Lease as to the assigned premises. Consent by
Landlord to any one assignment or subletting shall not in any way be construed
as relieving Tenant from obtaining the Landlord's expressed written consent to
any further assignment or subletting.

         13.3 Landlord to Approve Documents. All documents utilized by Tenant to
evidence any subletting or assignment to which Landlord has consented shall be
subject to prior approval by Landlord or its attorney. Tenant shall pay on
demand all Landlord's costs and expenses, including reasonable attorneys' fees,
incurred in determining whether or not to consent to any requested subletting or
assignment and in reviewing and approving such documentation which shall not
exceed $500.

                                   SECTION 14
                              SIGNS AND ADVERTISING

         Tenant shall not install, paint, display, inscribe, place, or affix any
sign, picture, advertisement, notice, lettering, or direction in the interior of
the Leased Premises which is visible from the outside of the Building, or on the
exterior of the Building without the prior written consent of Landlord unless
provided for in the Plans.

                                   SECTION 15
                      DAMAGE TO PROPERTY, INJURY TO PERSONS

         15.1 Damage by Tenant. Tenant agrees to pay for all damage to the
Building or the Premises, as well as all damage to tenants or occupants thereof
caused by Tenant's misuse or neglect of the Premises, its apparatus or
appurtenances, or caused by any licensee, contractor, agent, or employee of
Tenant. Notwithstanding the foregoing provisions, neither Landlord nor Tenant
shall be liable to one another for any loss, damage, or injury caused by its act
or neglect to the extent that the other party has recovered the amount of such
loss, damage, or injury from an insurer and the insurance company is bound by
this waiver of liability.

         15.2 Tenant's Property. Particularly, but not in limitation of the
foregoing paragraph, all property belonging to Tenant, or any occupant of the
Premises, that is in the Building or the Premises, shall be there at the risk of
Tenant or other person only, and Landlord or its agents or employees (except in
the case of gross negligence of Landlord or its agents or employees) shall not
be liable for: (i) damage to or theft or misappropriation of such property; (ii)
any damage to property entrusted to Landlord, its agents, or employees, if any;
(iii) loss of or damage to any property by theft or otherwise, by any means
whatsoever; (iv) any injury or damage to persons or property resulting from
fire, explosion, falling plaster, steam, gas, electricity, snow, hail, water, or
rain which may leak from any part of the Building or from the pipes, appliances,
or plumbing works therein or from the roof, street, subsurface, or from any
other place, or resulting from


                                      -12-

<PAGE>   16


dampness or any other cause whatsoever; or (v) interference with the light, air,
or other incorporeal hereditament. Tenant shall give prompt notice to Landlord
in case of fire or accidents in the Premises or in the Building or of observed
defects in the Building, its fixtures or equipment.

                                   SECTION 16
                               TENANT'S INSURANCE

         16.1 Insurance. Tenant shall, during the entire Term of this Lease, at
its sole cost and expense, obtain, maintain, and keep in full force and effect
the following types of insurance:

                  (a) All risk coverage insurance, including endorsements for
vandalism, malicious mischief, theft, sprinkler leakage, covering all of
Tenant's property, including, but not limited to, furniture, fittings,
equipment, installations, alterations, additions, partitions, fixtures, and
anything in the nature of a leasehold improvement in an amount equal to the full
replacement cost of such property without deduction for depreciation.

                  (b) Commercial general liability insurance, including bodily
injury and property damage, personal injury, contractual liability with respect
to all claims, demands, or actions by any person, firm, or corporation, in any
way arising from, related to, or connected with the conduct and operation of
Tenant's business in the Premises or Tenant's use of the Premises. Such policies
shall be written on a comprehensive basis, with limits not less than
$1,000,000.00, and such higher limits as Landlord or the mortgagees of Landlord
may require from time to time, but may not be unreasonably required.

                  (c) Any other form or forms of insurance as the mortgagees of
Landlord may reasonably require from time to time in form, in amounts and for
insurance risks against which a prudent tenant would protect itself.

         16.2 Evidence. All policies shall be taken out with insurers acceptable
to Landlord and in form satisfactory from time to time to Landlord. Tenant
agrees that certificates of insurance or, if required by Landlord or the
mortgagees of Landlord, copies of each such insurance policy will be delivered
to Landlord as soon as practicable after the placing of the required insurance,
but in no event later than five (5) days after Tenant takes possession of all or
any part of the Leased Premises. All policies shall require that at least thirty
(30) days' prior written notice be delivered to Landlord by the insurer prior to
termination, cancellation, or material change in such insurance.

         16.3 Proceeds. Tenant agrees that in the event of damage or destruction
to the leasehold improvements in the Leased Premises covered by insurance
required to be taken out by Tenant pursuant to this Section, Tenant shall use
the proceeds of the insurance for the purpose of building leasehold improvements
appropriate to the continuation of Tenant's business from the Premises. Landlord
shall have the right to review and approve the plans, which approval will not be
unreasonably withheld. In the event of damage or destruction of the Building
entitling the Landlord to terminate this Lease pursuant to Section 17, then, if
the Leased Premises have also been damaged, Tenant will pay to Landlord all of
its insurance proceeds relating to the leasehold


                                      -13-

<PAGE>   17


improvements in the Leased Premises owned by Landlord pursuant to the terms of
the Lease, and if the Leased Premises have not been damaged, Tenant will deliver
to Landlord, in accordance with the provisions of this Lease, the leasehold
improvements and the Leased Premises.

                                   SECTION 17
                              DAMAGE OR DESTRUCTION

         17.1 Right to Terminate. If the Premises or the Building are damaged by
fire or other insured casualty, and the insurance proceeds have been made
available by the holder or holders of any mortgages or deeds of trust covering
the Building, the damage shall be repaired by and at the expense of Landlord to
the extent of such insurance proceeds available, provided such repairs can, in
Landlord's reasonable discretion, be completed within one hundred twenty (120)
days after the occurrence of such damage, without the payment of overtime or
other premiums. Until the repairs are completed, the Rent shall be abated in
proportion to the part of the Premises which is unusable by Tenant in the
conduct of its business. If repairs cannot, in Landlord's reasonable discretion,
be made within said one hundred twenty (120) day period, Landlord shall notify
Tenant within sixty (60) days of the date of occurrence of the damage as to
whether or not Landlord elects to make the repairs. If Landlord elects not to
make the repairs, then either party may, by written notice to the other, cancel
this Lease as of the date of the occurrence of the damage. Except as provided in
this Section 17, there shall be no abatement of Rent and no liability of
Landlord by reason of any injury, inconvenience, temporary limitation of access
or interference to or with Tenant's business or property arising from the making
of any necessary repairs, or any alterations or improvements in or to any
portion of the Building or the Premises, or in or to fixtures, appurtenances,
and equipment therein necessitated by the damage. Tenant understands that
Landlord will not carry insurance of any kind on Tenant's furniture and
furnishings or on any fixtures or equipment removable by Tenant under the
provision of this Lease, and that Landlord shall not be required to repair any
injury or damage caused by fire or other cause, or to make any repairs or
replacements to or of improvements installed in the Premises by or for Tenant at
Tenant's cost.

         17.2 Landlord's Insurance. Landlord covenants and agrees that,
throughout the Lease Term, it will insure the Building (excluding foundations,
excavations and other non-insurable items) and the machinery, boilers, and
equipment contained therein owned by Landlord (excluding any property with
respect to which Tenant is obliged to insure pursuant to the provisions of
Section 16 thereof) against damage by fire and extended perils coverage in such
reasonable amounts as would be carried by a prudent owner of a similar property
in the same locale. Landlord will also, throughout the Term, carry commercial
general liability, property damage and loss of rent insurance with respect to
the operation of the Premises in reasonable amounts as would be carried by a
prudent owner of a similar property in the same locale. Landlord may, but shall
not be obligated to, take out and carry any other form or forms of insurance as
it or the mortgagees of Landlord may reasonably determine to be advisable.
Tenant shall pay its proportionate share for all such insurance carried by
Landlord as an Operating Cost, provided that such insurance is not duplicative
of the insurance obtained pursuant to Section 16.1. Notwithstanding any
contribution by Tenant to the cost of insurance premiums, Tenant acknowledges
that it has no right to receive any proceeds from the insurance policies carried
by


                                      -14-

<PAGE>   18



Landlord, and that the insurance will be for the sole benefit of Landlord, with
no coverage for Tenant for any risk insured against.

                                   SECTION 18
                                ENTRY BY LANDLORD

         Landlord and its agents, upon giving 24 hours notice, shall have the
right to enter the Premises during normal business hours for the purpose of
examining or inspecting the same, to supply any services to be provided by
Landlord to Tenant hereunder, to show same to prospective purchasers or tenants
of the Premises, and to make such alterations, repairs, improvements, or
additions, whether structural or otherwise, to the Premises or to the Building
as Landlord may deem necessary or desirable. Landlord may enter by means of a
master key, without liability to Tenant except for any failure to exercise due
care for Tenant's property, and without affecting this Lease. Landlord shall use
reasonable efforts on any such entry not to unreasonably interrupt or interfere
with Tenant's use and occupancy of the Premises. Landlord may enter the Premises
at any time in the case of an emergency. Landlord will only show the Premises to
prospective Purchasers or Tenants upon twenty-four (24) hours notice and then
only with a representative of Tenant present in order to protect the
confidentiality and trade secret aspects of Tenant's operations.

                                   SECTION 19
                                DEFAULT BY TENANT

         19.1 Events of Default. Each one of the following events is referred to
as an "Event of Default":

                  (a) Tenant shall fail to make due and punctual payment of Rent
or any other amounts payable hereunder, and such failure shall continue for
fifteen (15) days after receipt of written notice from Landlord.

                  (b) Tenant shall vacate or abandon the Premises and cease
payment of Rent, or remove leasehold improvements or fixtures constituting
property of Landlord;

                  (c) This Lease shall be transferred to or shall pass to or
devolve upon any other person or party except in the manner set forth in Section
13;

                  (d) This Lease or the Premises or any part thereof shall be
taken upon execution or by other process of law directed against Tenant, or
shall be taken upon or subject to any attachment at the instance of any creditor
of, or claimant against Tenant, and said attachment shall not be discharged or
disposed of within sixty (60) days after the levy;

                  (e) Tenant shall file a petition in bankruptcy or insolvency
or for reorganization or arrangement under the bankruptcy laws of the United
States or under any insolvency act of any state, or shall voluntarily take
advantage of any such law or act by answer or otherwise, or shall be dissolved
or shall make an assignment for the benefit of creditors;


                                      -15-

<PAGE>   19


                  (f) Involuntary proceedings under any such bankruptcy law or
insolvency act or for the dissolution of Tenant shall be instituted against
Tenant, or a receiver or trustee shall be appointed of all or substantially all
of the property of Tenant, and such proceedings shall not be dismissed or such
receivership or trusteeship vacated within sixty (60) days after such
institution or appointment;

                  (g) Tenant shall fail to pay Rent and shall fail to take
possession of the Premises thirty (30) days following the earlier of the date
the Premises are Ready for Occupancy or the Commencement Date;

                  (h) Tenant shall fail to perform any of the other agreements,
terms, covenants or conditions of this Lease on Tenant's part to be performed,
and such nonperformance shall continue for a period of thirty (30) days after
written notice by Landlord to Tenant, or if such performance cannot be
reasonably had within such thirty (30) day period, Tenant shall not in good
faith have commenced such performance within such thirty (30) day period and
shall not thereafter diligently proceed to completion.

         19.2 Remedies of Landlord. If any one or more Events of Default shall
happen which are not timely cured, then Landlord shall have the right at
Landlord's election, or at any time thereafter, to reenter and take possession
of the Premises or any part thereof by proper legal process and repossess the
same as Landlord's former estate and expel Tenant and those claiming through or
under Tenant, and remove the effects of both or either, without being deemed
guilty of any manner of trespass, and without prejudice to any remedies for
arrears of Rent or breach of covenants or prior conditions and without
terminating this Lease. Should Landlord elect to reenter as provided in this
Subsection, or should Landlord take possession pursuant to legal proceedings or
pursuant to any notice provided for by law including a proceeding for possession
pursuant to Colorado's Forcible Entry and Unlawful Detainer Statutes, Landlord
may, from time to time, without terminating this Lease either:

                  (a) (i) Relet the Premises or any part thereof in Landlord's
or Tenant's name, but for the account of Tenant, for a term or terms (which may
be greater or less than the period which would otherwise have constituted the
balance of the term of this Lease) and on conditions and upon other terms (which
may include repair of the Premises) as Landlord, in its commercially reasonable
discretion, may determine, and Landlord may collect and receive the rents.
Landlord shall use reasonable efforts to relet the Premises and maximize the
income generated by the Premises. No reentry or taking possession of the
Premises by Landlord shall be construed as an election on Landlord's part to
terminate this Lease unless a written notice of such intention be given to
Tenant. No notice from Landlord hereunder or under a forcible entry and unlawful
detainer statute or similar law shall constitute an election by Landlord to
terminate this Lease unless such notice specifically so states. Landlord
reserves the right following any reentry and/or reletting to exercise its right
to terminate this Lease by giving Tenant written notice, in which event the
Lease will terminate as specific in the notice.


                                      -16-

<PAGE>   20



                           (ii) If Landlord elects to take possession of the
Premises as provided in this Subsection (a) without terminating the Lease,
Tenant shall pay to Landlord (1) the Rent and other sums due under this Lease
which would be payable if repossession had not occurred, less (2) the net
proceeds, if any, of any reletting of the Premises after deducting Landlord's
expenses in connection with the reletting as follows: all repossession costs,
brokerage commissions, legal expenses and attorneys' fees, repair costs, and the
cost, prorated based on the number of years remaining under the Primary Term of
this Lease, of "freshening" the Premises for a new tenant, such as touch up
work, new paint and carpet, but not including the cost of the demolition and
replacement of the existing tenant finish work.

                  (b) To give Tenant written notice of intention to terminate
this Lease on the date of the notice, or on any later date specified in the
notice. Tenant's right to possession of the Premises shall cease and the Lease
shall thereupon be terminated, except as to Tenant's liability under this Lease,
as if the expiration of the term fixed in the notice were the end of the term
originally demised. If this Lease is terminated pursuant to the provisions of
this Subsection (b), or terminated pursuant to a proceeding for possession under
the Colorado Forcible Entry and Unlawful Detainer Statutes, Tenant shall remain
liable to Landlord for damages in an amount equal to the Rent and other sums
which would have been owing by Tenant under this Lease for the balance of the
Term had this Lease not been terminated, less the net proceeds, if any, of any
reletting of the Premises by Landlord subsequent to the termination, after
deducting Landlord's expenses in connection with such reletting, including the
expenses enumerated in Subsection (a) above. Landlord shall be entitled to
collect damages from Tenant monthly on the days on which the Rent and other
amounts would have been payable if this Lease had not been terminated.

         19.3 Cumulative Remedies. Suit or suits for the recovery of the Rent
and other amounts and damages may be brought by Landlord, from time to time, at
Landlord's election, and nothing in this Lease shall be deemed to require
Landlord to await the date when this Lease or its Term would have expired by
limitation had there been no default by Tenant, or no termination, as the case
may be. Each right and remedy provided for in this Lease shall be cumulative and
shall be in addition to every other right or remedy provided for in this Lease
or now or hereafter existing at law or in equity or by statute or otherwise
including but not limited to suits for injunctive relief and specific
performance. The exercise or beginning of the exercise by Landlord of any one or
more of the rights or remedies provided for in this Lease or now or hereafter
existing at law or in equity by statute or otherwise shall not preclude the
simultaneous or later exercise by Landlord of any or all rights or remedies
provided for in this Lease or now or hereafter existing at law or in equity or
by statute or otherwise. All such rights and remedies shall be considered
cumulative and non-exclusive. All costs incurred by Landlord in connection with
collecting any Rent or other amounts and damages owing by Tenant pursuant to the
provisions of this Lease, or to enforce any provision of this Lease, including
reasonable attorney's fees from the date such matter is turned over to an
attorney, and an action is commenced by Landlord, shall also be paid by Tenant
to Landlord.

         19.4 No Waiver. No failure by Landlord to insist upon the strict
performance of any agreement, term, covenant or condition of this Lease or to
exercise any right or remedy consequent upon a breach, and no acceptance of full
or partial payment of Rent during the


                                      -17-

<PAGE>   21



continuance of any breach, shall constitute a waiver of any breach or of the
agreement to be performed or complied with by Tenant, and no breach shall be
waived, altered or modified except by written instrument executed by Landlord.
No waiver of any breach shall affect or alter this Lease, but each and every
agreement, term, covenant and condition shall continue in full force and effect
with respect to any other then existing or subsequent breach. Notwithstanding
any termination of this Lease, the same shall continue in force and effect as to
any provisions which require observance or performance by Landlord or Tenant
subsequent to such termination.

         19.5 Bankruptcy. Nothing contained in this Section 19 shall limit or
prejudice the right of Landlord to prove and obtain as liquidated damages in any
bankruptcy, insolvency, receivership, reorganization or dissolution proceeding,
an amount equal to the maximum allowed by any statute or rule of law governing
such a proceeding, and in effect at the time when such damages are to be proved,
whether or not the amount is greater, equal to or less than the amounts
recoverable, either as damages or Rent, referred to in any of the preceding
provisions of this Section. Notwithstanding anything contained in this Section
to the contrary, any such proceeding or action involving bankruptcy, insolvency,
reorganization, arrangement, assignment for the benefit of creditors, or
appointment of a receiver or trustee, as set forth above, shall be considered to
be an event of default only when the proceeding, action or remedy shall be taken
or brought by or against the then holder of the leasehold estate under this
Lease.

                                      TAXES

         During the Term hereof, Tenant shall pay, prior to delinquency, all
business and other taxes, charges, notes, duties and assessments levied, and
rates or fees imposed, charged, or assessed against or in respect of Tenant's
occupancy of the Leased Premises or in respect of the personal property, trade
fixtures, furnishings, equipment, and all other personal property of Tenant

                                 EMINENT DOMAIN

         21.1 If the Building, or a substantial part thereof, or a substantial
part of the Premises or Common Areas, shall be lawfully taken or condemned (or
conveyed under threat of such taking or condemnation) for any public or
quasi-public use or purpose, the Term of this Lease shall end upon, and not
before, the date of the taking of possession by the condemning authority.
Current Rent shall be apportioned as of the date of termination. If any part of
the Building, other than the Premises or not constituting a substantial part of
the Premises, shall be so taken or condemned (or conveyed under threat of such
taking or condemnation), or if the grade of any street adjacent to the Building
is changed by any competent authority and such taking or change of grade makes
it necessary or desirable to substantially remodel or restore the Building,
which could not be accomplished without the total relocation of Tenant, Landlord
shall have the right to cancel this Lease upon not less than sixty (60) days'
notice prior to the date of cancellation designated in the notice. No money or
other consideration shall be payable by Landlord to Tenant for the right of
cancellation, and Tenant shall have no right to share in any condemnation award,
or in any judgment for damages, or in any proceeds of any sale made under any
threat of condemnation or taking. Nothing in this Section shall prevent Tenant
from making and pursuing a claim against the condemning authority in its own
right for termination of its leasehold interest, moving costs and other amounts
to which Tenant may be entitled. If this Lease is not canceled, the Lease shall
continue in full force and effect, and Rent shall be equitably abated in
proportion to any reduction in the size and utility of the Premises.

                                   SECTION 22
                  SUBORDINATION TO MORTGAGES AND DEEDS OF TRUST

         22.1 Lease Subordinate to Mortgages.

                  (a) Landlord agrees to require each lienholder against the
Premises to execute a non-disturbance agreement in favor of Tenant. This Lease
and the rights of Tenant shall be and are hereby made subject and subordinate to
the lien of any mortgages or deeds of trust as to which Tenant has received a
non-disturbance agreement now or hereafter existing against the Building, the
Property or both, and to all renewals, modifications, consolidations,
replacements and extensions thereof and to all advances made now or in the
future. Although the subordination shall be selfoperating, Tenant, or its
successors in interest, shall upon Landlord's request, execute and deliver upon
the demand of Landlord any and all instruments desired by Landlord,
subordinating, in the manner reasonably requested by Landlord, this Lease to any
mortgage or deed of trust. Landlord is hereby irrevocably appointed and
authorized as agent and attorney-in- fact of Tenant to execute all subordination
instruments if Tenant fails to execute the instruments within ten (10) days
after notice from Landlord demanding their execution. The notice may be given in
the manner provided for giving notice below.

                  (b) Should any mortgage or deed of trust affecting the
Building, the Property or both be foreclosed by a Lender which has granted
Tenant a non-disturbance agreement, then: (i) the liability of the mortgagee,
beneficiary or purchaser at the foreclosure sale to Tenant shall


                                      -19-

<PAGE>   23



exist only so long as the mortgagee, beneficiary, or purchaser is the owner of
the Building and/or Property and the liability shall not continue or survive
after further transfer of ownership; and (ii) Tenant shall be deemed to have
attorned, as Tenant under this Lease, to the purchaser at any foreclosure sale
and this Lease shall continue in force and effect as a direct lease between and
binding upon Tenant and the purchaser at any foreclosure sale. As used in this
Section 22, "mortgagee" and "beneficiary" shall include successors and assigns
of any such party, whether immediate or remote, the purchaser of any mortgage or
deed of trust, whether at foreclosure or otherwise, and the successors,
assignees, mortgagees, and beneficiaries of such purchaser, whether immediate or
remote.

         22.2 Tenant's Notices. In the event of any act or omission by Landlord
under this Lease which would give Tenant the right to terminate this Lease, or
to claim a partial or total eviction, Tenant will not exercise any such right
until:

                  (a) it has given thirty days written notice (by United States
certified or registered mail, postage prepaid) of such act or omission to the
holder of any mortgage or deed of trust on the Property (whose names and
addresses Landlord has previously furnished to Tenant) with a copy to Joel C.
Davis, Dietze & Davis, P.C., P.O. Box 1530, Boulder, Colorado 80306; and
O'Connor Development, 287 Century Circle, Suite 101, Louisville, Colorado 80027;
and

                  (b) any holder of any mortgage or deed of trust on the
Property shall, following the giving of such notice, have failed with reasonable
diligence to commence and to pursue reasonable action to remedy the act or
omission within not more than sixty (60) days.

                                   SECTION 23
                                     WAIVER

         The waiver by Landlord of any breach of any term, covenant, or
condition in this Lease shall not be deemed to be a waiver of the term,
covenant, or condition, or any subsequent breach of the same or any other term,
covenant or conditions. The acceptance of Rent hereunder shall not be construed
to be a waiver of any breach by Tenant of any term, covenant, or condition of
this Lease, it being understood and agreed that the remedies given to Landlord
shall be cumulative, and the exercise of any one remedy by Landlord shall not be
to the exclusion of any other remedy.

                                   SECTION 24
                                   SUBROGATION

         The parties to this Lease agree that any and all fire and extended
coverage insurance which is required to be carried by either shall be endorsed
with a subrogation clause, substantially as follows: "This insurance shall not
be invalidated should the insured waive, in writing, prior to a loss, any and
all right of recovery against any party for loss occurring to the property
described herein." Each party waives all claims for recovery from the other
party, its officers, agents or employees for any loss or damage (whether or not
such loss or damage is caused by negligence of the other party, and
notwithstanding any provisions contained in this Lease to the contrary) to any


                                      -20-

<PAGE>   24



of its real or personal property insured under valid and collectible insurance
policies to the extent of the collectible recovery under the insurance.

                                PLATS AND RIDERS

         Appendices, clauses, plats, and riders, if any, referred to in this
Lease and signed or initialed by Landlord and Tenant and affixed to this Lease
are hereby incorporated in and made a part of this Lease.

                                   SECTION 26
                                SALE BY LANDLORD

         In the event of a sale or conveyance or transfer by Landlord of its
interest in the Property and/or in the Building containing the Premises, and/or
in this Lease to a financially capable and responsible party, the same shall
operate to release Landlord from any future liability upon any of the covenants
or conditions, expressed or implied, contained in favor of Tenant, and in that
event, Tenant agrees to look solely to the responsibility of the successor in
interest of Landlord in and to this Lease. This Lease shall not be affected by
any such conveyance or transfer, and Tenant agrees to attorn to such purchaser
or transferee.

                                   SECTION 27
                          RIGHT OF LANDLORD TO PERFORM

         All covenants and agreements to be performed by Tenant under any of the
terms of this Lease shall be performed by Tenant at Tenant's sole cost and
expense, and without any abatement of Rent. If Tenant shall fail to pay any sum
of money, other than Rent, required to be paid by it, or shall fail to perform
any other act on its part to be performed, and the failure shall continue for
thirty (30) days after written notice by Landlord, Landlord may, but shall not
be obligated to do so, and without waiving or releasing Tenant from any
obligations of Tenant, make any payment or perform any other act on Tenant's
part to be made or performed as in this Lease provided. All sums so paid by
Landlord and all necessary incidental costs, together with interest at the rate
of 4% over the Prime Rate announced from time to time by Norwest Bank, Denver,
from the date of a payment by Landlord, shall be payable to Landlord on demand,
and Tenant covenants to pay any such sums, and Landlord shall have (in addition
to any other right or remedy of Landlord) the same rights and remedies in the
event of the non-payment thereof by Tenant, as in the case of default by Tenant
in the payment of Rent.

                                   SECTION 28
                                 ATTORNEY'S FEES

         In the event of any litigation or arbitration between Tenant and
Landlord to enforce any provision of this Lease or any right of either party,
the unsuccessful party to such litigation or arbitration shall pay to the
successful party all costs and expenses, including reasonable attorney's fees,
incurred. Moreover, if Landlord, without fault, is made a party to any
litigation instituted by



                                      -21-

<PAGE>   25


or against Tenant, Tenant shall indemnify Landlord against, and protect, defend,
and save it harmless from, all costs and expenses, including attorney's fees,
incurred by Landlord.

                                   SECTION 29
                              ESTOPPEL CERTIFICATE

         Tenant shall, at any time and from time to time but not more often than
once per year, upon not less than ten (10) days' prior written notice from
Landlord, execute, acknowledge, and deliver to Landlord a statement in writing
certifying that this Lease is unmodified and in full force and effect (or if
modified, stating the nature of such modification and certifying that this
Lease, as so modified, is in full force and effect) and the dates to which the
Rent and other charges are paid, and acknowledging that Tenant is paying Rent on
a current basis with no offsets or claims, and there are not, to Tenant's
knowledge, any uncured defaults on the part of Landlord hereunder (or specifying
the offsets, claims, or defaults, if any are claimed). It is expressly
understood and agreed that any such statement may be relied upon by any
prospective purchaser or encumbrance of all or any portion of the Building or by
any other person to whom it is delivered. Tenant's failure to deliver the
statement within the required time shall be conclusive upon Tenant that this
Lease is in full force and effect, without modification except as may be
represented by Landlord, that there are no uncured defaults in Landlord's
performance, and that not more than two (2) months' rental have been paid in
advance.

                                   SECTION 30

be mailed by registered or certified mail, return receipt requested, addressed
to Tenant at the Premises or to Landlord at the place from time to time
established for the payment of Rent. Notices shall be effective when delivered,
if served personally, or three (3) days after mailing, if mailed. If no one at
the premises is available to accept the notice, then it shall be deemed
effective upon the second refusal or returned mail delivery attempt.

         Landlord and Tenant reserve the following rights, exercisable without
notice and without liability to Tenant for damage or injury to property, person,

expressly set forth in Adaptec's Disclosure Letter, all of the following
statements, representations and warranties are true and correct:

         SECTION 3.1. Organization and Good Standing of Adaptec. Adaptec is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation and is in good standing in each
jurisdiction in which Business Assets are located. Adaptec has all requisite

be, duly executed and delivered by Adaptec. This Agreement constitutes, and,
upon Adaptec's execution of each of the other Ancillary Agreements and the
Adaptec Closing Documents, each of the other Ancillary Agreements and each of
the Adaptec Closing Documents will constitute, a legal, valid and binding
obligation of Adaptec enforceable against Adaptec in accordance with its terms,
except (i) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium, and other laws of general application affecting enforcement of
creditors' rights generally; and (ii) as limited by laws relating to the

remedies. The execution, delivery and performance by Adaptec of this Agreement
and each of the Ancillary Agreements have been duly and validly approved and
authorized by Adaptec's Board of Directors.

         SECTION 3.3. No Conflict. The execution, delivery and performance of
this Agreement, the Ancillary Agreements and the Adaptec Closing Documents by
Adaptec and the consummation of the transactions contemplated hereby do not and
will not (a) result in a violation or default in any material respect of any
provision of Adaptec's charter documents or any judgment, order, writ or decree
applicable to Adaptec or to any of the Business Assets or (b) result in the
creation of any material Encumbrance on any of the Business Assets.

         SECTION 3.4. Consents. No consent, approval, order or authorization of
or registration, qualification, designation, declaration or filing with, any
governmental entity on the part of Adaptec is required in connection with the
consummation of the transactions contemplated by this Agreement and the
Ancillary Agreements.

         SECTION 3.5. Title to Assigned Assets. Adaptec owns all the Assigned
Assets and has good and marketable title in and to all of the Assigned Assets,

<PAGE>   7
clear of all material Encumbrances without obtaining the consent or approval of
any person. Schedule 1 was prepared in the ordinary course, in a manner
consistent with Adaptec's past practice and in accordance with Adaptec's
business records.

         SECTION 3.6. No Restrictive Agreements. No Business Asset is bound or
affected by any judgment, injunction, order, decree, contract, covenant or
agreement that restricts or prohibits Adaptec (or would restrict Chaparral) from
freely engaging in the ESS Business as now conducted.

         SECTION 3.7. Litigation. There is no claim, action, suit, arbitration,
mediation, investigation or other proceeding of any nature pending or, to the
best of Adaptec's knowledge, threatened, at law or in equity, by way of
arbitration or before any court, governmental department, commission, board or
agency that: (i) may adversely affect, contest or challenge Adaptec's authority,
right or ability to transfer or convey any of the Business Assets to Chaparral
hereunder or otherwise perform Adaptec's obligations under this Agreement or any
of the Ancillary Agreements; (ii) challenges or contests Adaptec's right, title
or ownership of any of the Business Assets or seeks to impose an Encumbrance on,
or a transfer of title or ownership of, any Business Asset or (iii) asserts that
any Business Asset, or any action taken by any employee, consultant or
contractor of Adaptec with respect to any Business Asset, infringes or
misappropriates any Intellectual Property Rights of any third party.

         SECTION 3.8. Intellectual Property Rights.

         (a) Ownership. Adaptec is the sole and exclusive owner or has the right
to use the Business Assets pursuant to license, sublicense, agreement, or other
valid permission, all intellectual property rights necessary for the manufacture
and sale of the Products conducted.

         (b) No Infringement. To Adaptec's knowledge, the Products and, as and
to the extent used in the development of or integrated or incorporated in or
with the Products, the other Licensed Assets have not infringed or violated and
currently do not infringe or violate upon, or misappropriate any copyright, mask
work or trade secret, or any patent or other intellectual property rights (other
than trademarks) of any third party, and no third party has asserted or
threatened to assert against Adaptec any claim of infringement or
misappropriation of any such rights. To Adaptec's knowledge, no third party has
interfered with, infringed upon, misappropriated, or otherwise come into
conflict with any of the Intellectual Property Rights in any manner affecting
the ESS Business.

         (c) Licenses. Adaptec has not granted to any third party any right to
the Business Assets inconsistent with the rights granted to Chaparral hereunder.

         SECTION 3.9. Acquisition for Own Account. The Preferred Shares will be
acquired for investment for Adaptec's own account, not as a nominee or agent,
and not with a view to the public resale or distribution thereof within the
meaning of the 1933 Act, and Adaptec has no present intention of selling,
granting any participation in, or otherwise distributing the same.

         SECTION 3.10. Investment Experience. Adaptec understands that the
acquisition of the Preferred Shares involves substantial risk. Adaptec: (a) has
experience as Adaptec in securities of companies in the development stage and
acknowledges that Adaptec is able to fend for itself, can bear



                                      -7-
<PAGE>   8



the economic risk of Adaptec's investment in the Preferred Shares and warrant
and has such knowledge and experience in financial or business matters that
Adaptec is capable of evaluating the merits and risks of this investment in the
Preferred Shares and protecting its own interests in connection with this
investment and/or (b) has a preexisting personal or business relationship with
Chaparral and certain of its officers, directors or controlling persons of a
nature and duration that enables Adaptec to be aware of the character, business
acumen and financial circumstances of such persons.

         SECTION 3.11. Accredited Adaptec Status. Adaptec is an "accredited
investor" within the meaning of Regulation D promulgated under the 1933 Act.

         SECTION 3.12. Restricted Securities. Adaptec understands that the
Preferred Shares are characterized as "restricted securities" under the 1933 Act
inasmuch as they are being acquired from Chaparral in a transaction not
involving a public offering and that under the 1933 Act and applicable
regulations thereunder such securities may be resold without registration under
the 1933 Act only in certain limited circumstances. In this connection, Adaptec
represents that Adaptec is familiar with Rule 144 of the U.S. Securities and
Exchange Commission (the "SEC"), as presently in effect, and understands the
resale limitations imposed thereby and by the 1933 Act. Adaptec understands that
Chaparral is under no obligation to register any of the securities sold
hereunder except as provided in Investors Rights Agreement. Adaptec understands
that no public market now exists for any of the Preferred Shares and Conversion
Shares (collectively, the "SECURITIES") and that it is uncertain whether a
public market will ever exist for the Securities.

         SECTION 3.13. Further Limitations on Disposition. Without in any way
limiting the representations set forth above, Adaptec further agrees not to make
any disposition of all or any portion of the Securities unless and until:

         (a) there is then in effect a registration statement under the 1933 Act
covering such proposed disposition and such disposition is made in accordance
with such registration statement; or

         (b) Adaptec shall have notified Chaparral of the proposed disposition,
shall have furnished Chaparral with a statement of the circumstances surrounding
the proposed disposition, and, at the expense of Adaptec or its transferee,
shall have furnished Chaparral with an opinion of counsel, reasonably
satisfactory to Chaparral, that such disposition will not require registration
of such securities under the 1933 Act.

         Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be required for any transfer
of any Securities in compliance with SEC Rule 144 or Rule 144A.

         SECTION 3.14. Legends. It is understood that the certificates
evidencing the Preferred Shares and Conversion Shares will bear the legends set
forth below:

               (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, As AMENDED (THE



                                      -8-
<PAGE>   9




         "ACT"), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE
         SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE
         AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT
         AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR
         EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE
         REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN
         INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE
         AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER
         TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE
         WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

         (b) Any legend required by the laws of the State of California,
including any legend required by the California Department of Corporations and
Sections 417 and 418 if the California Corporations Code or any other state
securities laws, including a legend substantially in the form of the following
on the certificates evidencing the Preferred Shares:

                  THE PREFERRED SHARES EVIDENCED BY THIS CERTIFICATE: (1) ARE
         CONVERTIBLE INTO SHARES OF COMMON STOCK OF CHAPARRAL AT THE OPTION OF
         THE HOLDER AT ANY TIME PRIOR TO AUTOMATIC CONVERSION THEREOF, AND (2)
         AUTOMATICALLY CONVERT INTO COMMON STOCK OF CHAPARRAL IN THE EVENT OF A
         PUBLIC OFFERING MEETING CERTAIN REQUIREMENTS OR UPON CERTAIN CONSENTS
         OF THE HOLDERS OF CHAPARRAL'S PREFERRED STOCK; ALL PURSUANT TO AND UPON
         THE TERMS AND CONDITIONS SPECIFIED IN CHAPARRAL'S CERTIFICATE OF
         INCORPORATION. A COPY OF SUCH CERTIFICATE OF INCORPORATION MAY BE
         OBTAINED, WITHOUT CHARGE, AT CHAPARRAL'S PRINCIPAL OFFICE.

         The legend set forth in (a) above shall be removed by Chaparral from
any certificate evidencing Preferred Shares and Conversion Shares upon delivery
to Chaparral of an opinion by counsel, reasonably satisfactory to Chaparral,
that a registration statement under the 1933 Act is at that time in effect with

license to, all patents, patent applications, trademarks, service marks, trade
names, copyrights, moral rights, mask works, trade secrets, confidential and
proprietary information, compositions of matter, formulas, designs, proprietary
rights, know-how and processes (all of the foregoing collectively hereinafter
referred to as the "PROPRIETARY ASSETS") necessary to enable it to carry on its
business as now conducted and as presently proposed to be conducted, without any
conflict with or infringement of the rights of others. To the best of
Chaparral's knowledge, no third party has any ownership right, title, interest,
claim in or lien on any of Chaparral's Proprietary Assets and Chaparral has
taken, and in the future Chaparral will use its best efforts to take, all steps
reasonably necessary to preserve its legal rights in, and the secrecy of, all
its Proprietary Assets, except those for which disclosure is required for
legitimate business or legal reasons.

         (b) Licenses; Other Agreements. Chaparral has not granted, and, to the
best of Chaparral's knowledge, there are not outstanding, any options, licenses
or agreements of any kind



                                      -12-
<PAGE>   13

relating to any Proprietary Asset of Chaparral, nor is Chaparral bound by or a
party to any option, license or agreement of any kind with respect to any of its
Proprietary Assets. Chaparral is not obligated to pay any royalties or other
payments to third parties with respect to the marketing, sale, distribution,
manufacture, license or use of any Proprietary Asset or any other property or
rights.

         (c) No Infringement. To the best of Chaparral's knowledge, Chaparral
has not violated or infringed, and is not currently violating or infringing, and

its employees or consultants) has violated or infringed or, by conducting its
business as proposed, would violate or infringe, any Proprietary Asset of any
other person or entity.

         (d) No Breach by Employee. Chaparral is not aware that any employee or
consultant of Chaparral is obligated under any agreement (including licenses,
covenants or commitments of any nature) or subject to any judgment, decree or
order of any court or administrative agency, or any other restriction that would
interfere with the use of his or her best efforts to carry out his or her duties
for Chaparral or to promote the interests of Chaparral or that would conflict
with Chaparral's business as proposed to be conducted. The carrying on of
Chaparral's business by the employees and contractors of Chaparral and the
conduct of Chaparral's business as presently proposed, will not, to the best of
Chaparral's knowledge, conflict with or result in a breach of the terms,
conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any of such employees or contractors or
Chaparral is now obligated. Chaparral does not believe it is or will be
necessary to utilize any inventions of any employees of Chaparral (or persons
Chaparral currently intends to hire) made prior to their employment by
Chaparral. At no time during the conception of or reduction of any of
Chaparral's Proprietary Assets to practice was any developer, inventor or other
contributor to such patents operating under any grants from any governmental
entity or agency or private source, performing research sponsored by any

Proprietary Assets.

Hire.

         (b) Chaparral Liability; Indemnity. Chaparral shall be liable for and
obligated to pay and indemnify, and hold Adaptec and its affiliates harmless

unknown, accrued or not accrued, fixed or contingent, or arising hereafter,
directly or indirectly, with respect to (i) the employment by Chaparral or

whatsoever, whether known or unknown, accrued or not accrued, fixed or
contingent or arising hereafter, directly or indirectly, with respect to any
claims of discrimination under federal, state or local law provided such claims
arise from such New Hire's employment or service with or termination by Adaptec.
Adaptec shall pay to all terminated New Hires, any liability for accrued
vacation, sick leave or similar benefits with respect to such New Hires
attributable to periods of employment or service with Adaptec, consistent with
Adaptec's policies and applicable law, and shall make such payment within the

use taxes pertaining to its purchase of the Products (and, if Products are to be

                  negligence or willful misconduct by Purchaser in the

                  commission of a felony or other offense involving moral

         as follows:

                           (i) Founders Stock. The Company will have the right

<PAGE>   3



                           (ii) Voluntary Termination. If Purchaser ceases to be
                  employed by the Company as a result of Purchaser's voluntary
                  termination, then the percentage set forth in the table below

                  longer employed by the Company as a result of Purchaser's
                  termination for Cause, then Purchaser's shares, except for the
                  initial 62% of Purchaser's shares which vested on the
                  Commencement Date, will be deemed to be "Unvested Shares" and

                  repurchase all unvested shares according to the table above.

                           (v) Notwithstanding anything in this agreement to the
                  contrary, upon an ownership change as defined in Section 6,
                  all of Purchaser's Founder's Stock will be deemed vested

                  (h) Transfer of Unvested Shares. Purchaser will not sell,
         pledge or otherwise transfer any unvested Shares, or any interest
         therein, except pursuant to an exercise of the Unvested Share Purchase
         Option.

         3. Right of First Refusal.

                  (a) Right of First Refusal. In the event Purchaser proposes to
         sell, pledge, or otherwise transfer any Vested shares (the "Transfer
         Shares") to any person or entity, including, without limitation, any
         shareholder of the Company, the Company will have the right to
         repurchase the Transfer Shares under the terms and subject to the
         conditions set forth in this Section 3 (the "Right of First Refusal").
         For purposes of this Section 3, a change in record ownership of Shares
         will be deemed a transfer subject to the Right of First Refusal whether
         or not such change in record ownership results in a change in the
         beneficial ownership of such Shares.

                  (b) Notice of Proposed Transfer. Prior to any proposed
         transfer of Transfer Shares, Purchaser will give a written notice (the
         "Transfer Notice") to the Company describing fully the proposed
         transfer, including the number of Transfer Shares, the name and address
         of the proposed transferee (the "Proposed Transferee") and, if the
         transfer is voluntary, the proposed transfer price, and containing
         information necessary to show the bona fide nature of the proposed
         transfer. In the event of a bona fide gift or



                                                                          Page 4

<PAGE>   5



         involuntary transfer, the proposed transfer price will be deemed to be
         the Fair Market Value of the Transfer Shares as determined by the
         Company's Board of Directors as of the date of the Transfer Notice,
         subject to Section 5 hereof. In the event Purchaser proposes to
         transfer any Vested Shares to more than one Proposed Transferee,
         Purchaser will provide a separate Transfer Notice for the proposed
         transfer to each Proposed Transferee.

                  (c) Bona Fide Transfer. In the event that the Company
         determines that the information provided by Purchaser in the Transfer
         Notice is insufficient to establish the bona fide nature of a proposed
         voluntary transfer, the Company will give Purchaser written notice of
         Purchasers failure to comply with the procedure described in this
         Section 3 and Purchaser will have no right to transfer the Transfer
         Shares without first complying with the procedure described in this
         Section 3.

                  (d) Exercise of the Right of First Refusal. In the event the
         proposed transfer is determined by the Company to be bona fide, the
         Company will have the right to purchase all, but not less than all, of
         the Transfer Shares (except as the Company and Purchaser otherwise
         agree) at the purchase price and on the terms set forth in the Transfer
         Notice by delivery to Purchaser of a notice of exercise of the Right of
         First Refusal within thirty (30) days after the date the Transfer
         Notice is delivered to the Company. The Company's exercise or failure
         to exercise the Right of First Refusal with respect to any proposed
         transfer described in a Transfer Notice will not affect the Company's
         right to exercise the Right of First Refusal with respect to any
         proposed transfer described in any other Transfer Notice. If the
         Company exercises the Right of First Refusal, the Company and Purchaser
         will thereupon consummate the sale of the Transfer Shares to the
         Company on the terms set forth in the Transfer Notice within sixty (60)
         days after the date the Transfer Notice is delivered to the Company
         (unless a longer period is offered by the Proposed Transferee);
         provided, however, that in the event the Transfer Notice provides for
         the payment for the Transfer Shares other than in cash, the Company
         will have the option of paying for the Transfer Shares by the
         discounted cash equivalent of the consideration described in the
         Transfer Notice, as reasonably determined by the Company. For purposes
         of the foregoing, cancellation of any indebtedness of Purchaser to the
         Company will be treated as payment to Purchaser in cash to the extent
         of the unpaid principal and any accrued interest canceled.

                  (e) Failure to Exercise the Right of First Refusal. If the
         Company fails to exercise the Right of First Refusal in full within the
         period specified in Section 3(d), Purchaser may conclude a transfer to
         the Proposed Transferee of the Transfer Shares on the terms and
         conditions described in the Transfer Notice, provided such transfer
         occurs not later than ninety (90) days following delivery to the
         Company of the Transfer Notice. The Company will have the right to
         demand further assurances from Purchaser and the Proposed Transferee
         (in a form satisfactory to the Company) that the transfer of the
         Transfer Shares was actually carried out on the terms and conditions
         described in the Transfer Notice. No Transfer Shares will be
         transferred on the books of the Company until the Company has received
         such assurances, if so demanded. Any proposed transfer on terms and
         conditions different from those described in the Transfer Notice, as
         well as any subsequent proposed transfer by Purchaser, will again be
         subject to the Right of First Refusal and will require compliance by
         Purchaser with the procedure described in this Section 3.

                  (f) Transferees of the Transfer Shares. All transferees of the
         Transfer Shares or any interest therein, other than the company, will
         be required as a condition of such transfer to agree in writing (in a
         form satisfactory to the Company) that such transferee will receive and
         hold such Transfer Shares or interests



                                                                          Page 5

<PAGE>   6



         subject to the provisions of this Section 3 providing for the Right of
         First Refusal with respect to any subsequent transfer. Any sale or
         transfer of any Shares will be void unless the provisions of this
         Section 3 are complied with.

                  (g) Transfers Not Subject to the Right of First Refusal. The
         Right of First Refusal will not apply to any transfer of Vested Shares
         to Purchaser's estate, members of Purchaser's family or trusts for the
         benefit of Purchaser or any member of Purchaser's family, provided that
         in each case the proposed transferee agrees in writing (in a form
         satisfactory to the Company) that such transferee will receive and hold
         such Vested Shares subject to the provisions of this Section 3
         providing for the Right of First Refusal with respect to any subsequent
         transfer. Neither will the Right of First Refusal apply to any transfer
         or exchange of the Shares if such transfer or exchange is in connection
         with an Ownership Change, as defined in Section 6 hereof. If the
         consideration received pursuant to such transfer or exchange consists
         of securities, such securities will remain subject to the Right of
         First Refusal unless the provisions of Section 3(h) result in a
         termination of the Right of First Refusal.

                  (h) Early Termination of the Right of First Refusal. The other
         provisions of this Section 3 notwithstanding, the Right of First
         Refusal will terminate, and be of no further force and effect, upon

                           (i) the occurrence of a Transfer of Control, as
                  defined in Section 6 hereof, or

                           (ii) the existence of a public market for the class
                  of securities subject to the Right of First Refusal (including
                  any securities issued in exchange for any Shares). A "public
                  market" will be deemed to exist if such securities are (1)
                  listed on a national securities exchange (as that term is used
                  in the Securities Exchange Act of 1934, as amended [the
                  "Exchange Act"]) or (2) traded in the over- the-counter market
                  and prices therefor are published daily on business days in a
                  recognized financial journal.

         4. Spousal Consent. If Purchaser is married on the date of this
Agreement, Purchaser's spouse will execute a Consent of Spouse in the form of
Exhibit A hereto, effective on the date hereof. Such consent will not be deemed
to confer or convey to the spouse any rights in the Shares that do not otherwise
exist by operation of law or the agreement of the parties. If Purchaser should
marry or remarry subsequent to the date of this Agreement, Purchaser will within
thirty (30) days thereafter obtain his or her new spouse's acknowledgment of and
consent to the existence and binding effect of all restrictions contained in
this Agreement by signing an additional Consent of Spouse in the form of Exhibit
A. Failure to provide an additional Consent of Spouse will be treated as a
transfer of all of Purchaser's Shares to such spouse and trigger the Company's
Right of First Refusal under Section 3 above.

         5. Appraisal. In the case of the Company's exercise of its Right of
First Refusal pursuant to Section 3 hereof with respect to a bona fide gift or
involuntary transfer referred to therein, if Purchaser disagrees with the
valuation determined by the Company's Board of Directors, Purchaser may, by
giving written notice to the Company within ten (10) days after being informed
of such valuation, request that the value of the Shares at issue be determined
by an independent appraiser to be selected by the Company. The Company will
select an appraiser to determine the value of such Shares within fifteen (15)
days after the Company's actual receipt of Purchaser's notice disputing the
valuation set by the Company's Board of Directors. Such appraiser will be
subject to the approval of Purchaser, which approval will not be unreasonably
withheld or delayed. Purchaser's approval



                                                                          Page 6

<PAGE>   7



or refusal to approve the appraiser must be given before the appraiser announces
a valuation. The value of such Shares, as determined by the appraiser, will be
conclusively binding on all of the parties concerned.

The expenses of appraisal will be borne equally by the Company and Purchaser.
Any time required to resolve valuation dispute will be added to the time period
in which the Company may exercise its Right of First Refusal under Section 3
hereof.

         6. Ownership Change and Transfer of Control. An "Ownership Change" will
be deemed to have occurred if any of the following events occur with respect to
the Company:

                  (a) the direct or indirect sale or exchange by the
         shareholders of the Company of all or substantially all of the capital
         stock of the Company;

                  (b) a merger or consolidation in which the Company is a party;

                  (c) the sale, exchange, or transfer of all or substantially
         all of the assets of the Company (other than a sale, exchange, or
         transfer to one ore more subsidiary corporations [as defined in section
         424(f) of the Internal Revenue Code of 1986, as amended (the "Code")]
         of the Company) or

                  (d) a liquidation or dissolution of the Company.

                  A "Transfer of Control" shall mean an Ownership Change in
         which the shareholders of the Company immediately before such Ownership
         Change do not retain, directly or indirectly, at least a majority of
         the beneficial interest in the voting stock or securities of the
         Company or any successor entity thereto immediately after such
         transaction.

         7. At-Will Employment. Unless specifically provided in another written
agreement signed by Purchaser and an executive officer of the Company (or
another executive officer of the Company if Purchaser is executive officer of
the Company), any employment of Purchaser by the Company is not for any definite
period of time, is at- will, and may be terminated at any time, with or without
cause, by Purchaser or by the Company. Nothing in this Agreement is intended to
change the nature of any such employment relationship.

         8. Assignment of Rights. The Company may assign its rights under
Section 2 or 3 hereof at any time, whether or not any event has occurred which
permits the Company to exercise such rights, to one or more persons, including
shareholders of the Company, who will have the right to so exercise such rights
in his, her or their own names and for his, her or their own account. If the
exercise of any such right requires the consent of the Delaware Commissioner of
Corporations, the parties agree to cooperate in requesting such consent.

         9. Adjustment to Shares Subject to Company's Rights. If, from time to
time during the term of this Agreement, there is any stock dividend or
liquidating dividend of cash and/or property, stock split, reverse stock split,
recapitalization, reclassification or other similar change in the character or
amount of any of the outstanding securities of the Company, then, in such event
any and all new, substituted or additional securities or other property to which
Purchaser is entitled by reason of his or her ownership of the Shares will be
immediately subject to the provisions of this Agreement on the same basis as all
Shares originally purchased hereunder, and will be included in



                                                                          Page 7

<PAGE>   8



the word "Shares" for all purposes of this Agreement with the same force and
effect as the Shares presently subject to this Agreement. For purposes of
Sections 2 and 3 hereof, while the total price payable to exercise the rights
provided in such sections will remain the same after each such event, the price
payable per share to exercise such rights will be appropriately adjusted.

         10. Initial Public Offering. Purchaser hereby agrees that in the event
of an initial underwritten public offering of securities (an "IPO") made by the
Company pursuant to an effective registration statement filed under the
Securities Act of 1933, as amended (the "Securities Act"), Purchaser will not
offer, sell, contract to sell, pledge, hypothecate, grant any option to purchase
or make any short sale of, or otherwise dispose of any securities of the Company
or any rights to acquire securities of the Company for such period of time from
and after the effective date of such registration statement as may be designated
by the managing underwriter(s) for the IPO; provided, however, that such period
of time will not exceed one hundred eighty (180) days from the effective date of
such registration statement. At the Company's request, Purchaser shall execute
and deliver to managing underwriter(s) an agreement, in customary form,
confirming Purchaser's obligations under this Section 10. The foregoing
restriction will not apply to securities registered in the IPO. Purchaser shall
be subject to the foregoing restriction only if all officers and directors of
the Company are also subject to similar arrangements.

         11. Legends. All certificates representing any Shares subject to the
provisions of this Agreement will the following legends:

                  (a) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
         TRANSFER RESTRICTIONS IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT
         BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR HIS OR HER
         PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL
         OFFICE OF THE COMPANY.

                  (b) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
         A RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF THE COMPANY OR ITS ASSIGNEE
         SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED
         HOLDER, OR HIS OR HER PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON
         FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

                  (c) THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
         SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN
         EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH
         SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701
         UNDER SUCH ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE
         HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE COMPANY,
         STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT
         FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

                  (d) Any legend required under applicable state securities
         laws.





                                                                          Page 8

<PAGE>   9

         12. Purchaser Representations and Warranties. In connection with the
proposed purchase of the Shares, Purchaser hereby agrees, represents and
warrants as follows:

                  (a) Investment Intent. Purchaser is purchasing the Shares
         solely for Purchasers own account for investment and not with a view
         to, or for resale in connection with, any distribution thereof within
         the meaning of the Securities Act. Purchaser does not have any present
         intention of selling, offering to sell or otherwise disposing of or
         distributing the Shares or any portion thereof; and the entire legal
         and beneficial interest of the Shares Purchaser is acquiring is being
         purchased for, and will be held for the account of, Purchaser only and
         neither in whole nor in part for any other person.

                  (b) Information Concerning the Company. Purchaser is aware of
         the Company's business affairs and financial condition and has acquired
         sufficient information about the Company to reach an informed and
         knowledgeable decision to acquire the Shares. Purchaser further
         represents and warrants that Purchaser has discussed the Company and
         its plans, operations and financial condition with its officers, has
         received all such information as Purchaser deems necessary and
         appropriate to enable Purchaser to evaluate the financial risk inherent
         in making an investment in the Shares and has received satisfactory and
         complete information concerning the business and financial condition
         and prospects of the Company in response to all inquiries in respect
         thereof.

                  (c) Economic Risk. Purchaser realizes that the purchase of the
         Shares will be a highly speculative investment, and Purchaser is able,
         without impairing his or her financial condition, to hold the Shares
         for an indefinite period of time and to suffer a complete loss of
         Purchaser's investment in the Shares.

                  (d) Restricted Securities. Purchaser understands and
         acknowledges that:

                           (i) The sale of the Shares has not been registered
                  under the Securities Act, and the Shares must be held
                  indefinitely unless a transfer of the Shares is subsequently
                  registered under the Securities Act or an exemption from such
                  registration is available, and that the Company is under no
                  obligation to register the Shares; and

                           (ii) The Company will make a notation in its records
                  of the aforementioned restrictions on transfer and legends.

                  (e) Rule 144. Purchaser is aware of the provisions of Rule
         144, promulgated under the Securities Act, which, in substance, permit
         limited public resale of "restricted securities" acquired, directly or
         indirectly, from the issuer thereof (or an affiliate of such issuer),
         in a nonpublic offering subject to the satisfaction of certain
         conditions, including among other things: the resale occurring not less
         than one year from the date Purchaser has purchased and paid for the
         Shares; the availability of certain public information concerning the
         Company; the sale being made through a broker in an unsolicited
         "broker's transaction" or in a transaction directly with a market maker
         (as said term is defined under the Exchange Act); and that any sale of
         the Shares may be made by him or her only in limited amounts during any
         three-month period. Purchaser understands that at the time Purchaser
         wishes to sell the Shares there may be no public market upon which to
         make such a sale, and that, even if such a public market then exists,
         the Company may not then be satisfying the current public information
         requirements of Rule 144, and that, in such event, Purchaser would be
         precluded from selling the Shares under Rule 144 even if the one-year
         minimum holding period



                                                                          Page 9

<PAGE>   10



         has been satisfied. Purchaser understands that in the event all of the
         requirements of Rule 144 are not satisfied, registration under the
         Securities Act or compliance with another exemption from such
         registration will be required; and that, notwithstanding the fact that
         Rule 144 is not exclusive, the Staff of the SEC has expressed its
         opinion that persons proposing to sell restricted securities other than
         in a registered offering or pursuant to Rule 144 will have a
         substantial burden of proof in establishing that an exemption from
         registration is available for such offers or sales, and that such
         persons and their respective brokers who participate in such
         transactions do so at their own risk.

                  (f) Further Limitations on Disposition. Purchaser further
         agrees that Purchaser will in no event make any disposition of all or
         any portion of the Shares unless:

                           (i) There is then in effect a registration statement
                  under the Securities Act covering such proposed disposition
                  and such disposition is made in accordance with said
                  registration statement; or

                           (ii) Purchaser has notified the Company of the
                  proposed disposition and furnished the Company with a detailed
                  statement of the circumstances surrounding the proposed
                  disposition, and Purchaser has furnished the Company with an
                  opinion of Purchaser's own counsel to the effect that such
                  disposition will not require registration of such shares under
                  the Securities Act, and such opinion of Purchaser's counsel
                  has been concurred in by counsel for the Company.

                  (g) Capacity to Protect Interests. Purchaser has (i) a
         preexisting personal or business relationship with the Company or one
         or more of its officers, directors, or controlling persons, consisting
         of personal or business contacts of a nature and duration to enable
         Purchaser to be aware of the character, business acumen and general
         business and financial circumstances of the person with whom such
         relationship exists, or (ii) such knowledge and experience in financial
         and business matters as to make Purchaser capable of evaluating the
         merits and risks of an investment in the Shares and to protect
         Purchaser's own interests in the transaction, or (iii) both such
         relationship and such knowledge and experience.

                  (h) No Qualification. Purchaser understands that the Shares
         have not been qualified under General Corporation Law. Purchaser
         understands that the Company is relying on Purchaser's representations
         and warrants that the Company is entitled to rely on such
         representations and that such reliance is reasonable.

         13. Escrow and Transfer Restrictions.

                  (a) Escrow. As security for Purchaser's faithful performance
         of the terms of this Agreement and to ensure the availability for
         delivery of Purchaser's Shares upon exercise of the Repurchase Option,
         Purchaser agrees to deliver to and deposit with the Company's legal
         counsel, Robert D. Baker, Attorney at Law (the "Escrow Agent"), as
         Escrow Agent, two originals of an Assignment Separate From Certificate
         duly endorsed (with date and number of shares blank) in the form
         attached hereto as Exhibit B, together with the certificate or
         certificates evidencing the Shares; said documents are to be held by
         the Escrow Agent pursuant to the Joint Escrow Instructions of the
         Company and Purchaser set forth in Exhibit C attached hereto and
         incorporated by this reference, which instructions will also be
         delivered to the Escrow Agent at the closing hereunder.



                                                                         Page 10

<PAGE>   11


                  (b) Rights as Shareholder. Purchaser will, during the term of
         this Agreement, exercise all rights and privileges of a shareholder of
         the Company with respect to the Shares deposited in said escrow, except
         that Purchaser will not sell, transfer, pledge, hypothecate or
         otherwise dispose of any Shares except in accordance with the terms of
         this Agreement.

                  (c) Transfers in Violation of Agreement. The Company will not
         be required to (i) transfer on its books any Shares which are sold or
         transferred in violation of any of the provisions of this Agreement or
         (ii) treat as owner of such Shares, or to accord the right to vote as
         such owner or to pay dividends to, any transferee to whom such Shares
         are so transferred.

         14. Tax Matters.

                  (a) Valuation of Shares. Purchaser understands that:

                           (i) The Shares have been valued by the Company, and
                  the Company believes such valuation represents a fair attempt
                  at reaching an accurate appraisal of their worth; Purchaser
                  understands, however, that the Company can give no assurances
                  that the Internal Revenue Service ("IRS") will not assert that
                  the value of the Shares on the date of purchase is greater
                  than so determined.

                           (ii) If the IRS were to succeed in a tax
                  determination under the Internal Revenue Service Code of 1986,
                  as amended (the "Code") that the Shares have value greater
                  than that upon which this transaction was based, the
                  additional value would constitute ordinary income as of the
                  date of its receipt. The additional taxes (and interest) due
                  would be payable by Purchaser, and there is no provision for
                  the Company to reimburse him or her for such tax liability,
                  and Purchaser assumes all responsibility for such potential
                  tax liability. The Company undertakes no obligation to inform
                  Purchaser of any change in the tax laws which may affect this
                  Agreement or its consequences.

                           (iii) The Company would be entitled to the benefit,
                  in any such transaction, if a determination were made prior to
                  the three (3) year statute of limitations period affecting the
                  Company, of an increase in its deduction for the excess amount
                  deemed paid, which would offset its operating profits, or, if
                  not profitable, would create a net operating loss carry
                  forward arising from operations in that year.

                  (b) Election Under Section 83(b) of the Code.

                           (i) Purchaser understands that Section 83 of the Code
                  taxes as ordinary income the difference between the amount
                  paid for the Shares and the Fair Market Value of the Shares as
                  of the date any restrictions on the Shares lapse. In this
                  context, "restriction" means the right of the Company to buy
                  back the stock pursuant to the Repurchase Option contained in
                  this Agreement. In the event the Company has registered its
                  securities under the Exchange Act, "restriction" with respect
                  to officers, directors and greater than 10% shareholders also
                  means the six (6) month period




                                                                         Page 11

<PAGE>   12



                  after the closing during which such officers, directors and
                  greater than 10% shareholders are subject to suit under
                  Section 16(b) of the Exchange Act. Purchaser understands that
                  he or she may elect to be taxed at the time the Shares are
                  purchased rather than when and as the Repurchase Option or six
                  (6) month Section 16(b) period expires by filing an election
                  under Section 83(b) of the Code with the IRS within thirty
                  (30) days from the date of purchase. Even if the Fair Market
                  Value of the Shares equals the amount paid for the Shares, the
                  election must be made to avoid adverse tax consequences in the
                  future. The form for making this election is attached as
                  Exhibit D hereto. Purchaser understands that failure to make
                  this filing timely will result in the recognition of ordinary
                  income by Purchaser, as the Repurchase Option lapses, or after
                  the lapse of the six (6) month Section 16(b) period, on the
                  difference between the purchase price and the Fair Market
                  Value of the Shares at the time such restrictions lapse.

                           (ii) Purchaser understands that he or she should
                  consult with the his or her tax advisor regarding the
                  advisability of filing with the IRS an election under Section
                  83(b) of the Code, which must be filed no later than thirty
                  (30) days after the date of this Agreement. Failure to file an
                  election under Section 83(b), if appropriate, may result in
                  adverse tax consequences to Purchaser. Purchaser acknowledges
                  that he or she has been advised to consult with a tax advisor
                  regarding the tax consequences to Purchaser of the purchase of
                  Shares hereunder. AN ELECTION UNDER SECTION 83(b) MUST BE
                  FILED WITHIN 30 DAYS AFTER THE DATE ON WHICH PURCHASER
                  PURCHASES THE SHARES. THIS TIME PERIOD CANNOT BE EXTENDED.
                  PURCHASER ACKNOWLEDGES THAT TIMELY FILING OF A SECTION 83(b)
                  ELECTION IS PURCHASER'S SOLE RESPONSIBILITY, EVEN IF PURCHASER
                  REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO FILE SUCH
                  ELECTION ON HIS OR HER BEHALF.

         15. Miscellaneous.

                  (a) Future Instruments. The parties agree to execute such
         further instruments and to take such further action as may reasonably
         be necessary to carry out the intent of this Agreement.

                  (b) Notice. Any notice required or permitted hereunder will be
         given in writing and will be deemed effectively given upon personal
         delivery or upon deposit in the United States Post Office, by
         registered or certified mail with postage and fees prepaid, addressed
         to the other party hereto at the address shown below that party's
         signature or at such other address as such party may designate by ten
         (10) days' advance written notice to the other party hereto.

                  (c) Successors and Assigns. This Agreement will inure to the
         benefit of the successors and assigns of the Company and, subject to
         the restrictions on transfer herein set forth, be binding upon
         Purchaser and Purchaser's heirs, executors, administrators, successors
         and assigns; provided, however, that Purchaser may not assign his or
         her rights under this Agreement without the Company's prior written
         consent.

                  (d) Entire Agreement; Applicable Law. This Agreement, together
         with the exhibits hereto, will be construed under the laws of the State
         of Colorado other than the conflict of laws and except for matters




                                                                         Page 12

         of corporate governance which shall be governed by and construed
         according to the laws of the State of Delaware, and constitutes the
         entire agreement of the parties with respect to the subject matter
         hereof, superseding all prior written or oral agreements, and no
         amendment or addition hereto will be deemed effective unless agreed to
         in writing by the parties hereto.

                  (e) Right to Specific Performance. Purchaser agrees that the
         Company will be entitled to a decree of specific performance of the
         terms hereof or an injunction restraining violation of this Agreement,
         said right to be in addition to any other remedies available to the
         Company.

                  (f) Delays. No failure on the part of any party to exercise or
         delay in exercising any right hereunder will be deemed a waiver
         thereof, nor will any such failure or delay, or any single or partial
         exercise of any such right, preclude any further or other exercise of
         such right or any other right.

                  (g) Partial Invalidity. If any provision of this Agreement, or
         the application thereof, is for any reason and to any extent determined
         by a court of competent jurisdiction to be invalid or unenforceable,
         the remainder of this Agreement and the application of such provision
         to other persons or circumstances will be interpreted so as best to
         reasonably effect the intent of the parties hereto. The parties agree
         to use their best efforts to replace such void or unenforceable
         provision of this Agreement with a valid and enforceable provision
         which will achieve, to the extent greatest possible, the economic,
         business and other purposes of the void or unenforceable provision.

                  (h) Counterparts. This Agreement may be executed in
         counterparts, each of which will be an original and all of which
         together will constitute one and the same agreement.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the day and year first above written.

                        FOUNDER STOCK PURCHASE AGREEMENT

         THIS AGREEMENT is made as of _____________, 1998, by and between
CHAPARRAL TECHNOLOGIES, INC., a Delaware corporation (the "Company"), and
_________________("Purchaser").

                                    RECITALS

         A. Purchaser is a founder of the Company; and

         B. The Company desires to issue and sell to Purchaser, and Purchaser
desires to acquire, Common Stock of the Company on the terms and conditions set
forth below.

         C. Purchaser understands that the opportunity to purchase Founders'
Stock is consideration given to each Founder for the prior services actually
rendered to the Company for no compensation during the founding of the Company.

         NOW, THEREFORE, the parties, intending to be legally bound, hereby
agree as follows:

         1. Purchase and Sale of Common Stock.

                  (a) Purchase and Sale. Purchaser agrees that the opportunity
         to purchase Founders' Stock is consideration for Purchaser's efforts
         with no compensation during the founding and formation of the Company.
         Purchaser agrees that said consideration is sufficient for those
         founding efforts and that award of Founders' Stock extinguishes any
         claims or additional compensation for those founding efforts, other
         than as set forth in any existing agreement. Subject to the terms of
         this Agreement, Purchaser agrees to purchase from the Company, and the
         Company agrees to sell to Purchaser, _________ shares of the Company's
         Common Stock (the "Shares") for an aggregate purchase price of $One
         Tenth of One Cent (or $0.001) per share. Purchaser will pay the
         purchase price to the Company, by cash or check, at the closing.

                  (b) Closing. The closing of the purchase and sale of the
         Shares will occur at the offices of the Company within one week after
         the date of this Agreement. If the closing has not occurred by such
         date, this Agreement will be terminated and have no further force and
         effect.

         2. Repurchase Option re: Termination for Cause.

                  (a) In the event of termination of Purchaser's employment or
         consulting arrangement with the Company (the "Employment Arrangement")
         for cause, (referred to as the "Termination for Cause"), the Company
         shall, upon the date of such Termination, have an irrevocable and
         exclusive option (the "Repurchase Option") to repurchase up to the
         total number of Purchaser's Shares at the Original Issuance Price per
         Share, as adjusted for stock splits, stock dividends, consolidations,
         and the like.

                  (b) Within sixty (60) days following Purchaser's Termination
         for Cause, the Company shall notify Purchaser as to whether it (or its
         assignee) wishes to purchase all or a portion of the Shares pursuant to
         the exercise of the Repurchase Option. If the Company (or its assignee)
         elects to purchase such Shares hereunder, it shall notify Purchaser, in
         writing, of its (or its assignee's) intention to purchase such Shares
         hereunder at the repurchase price per share set pursuant to Section 3.1
         (a), and either

                           (i) set a date and location for the closing of the
                  transaction not later than thirty (30) days from the date of
                  such notice, at which time the Company (or its assignee) shall
                  tender payment for the Shares, or

                           (ii) close the transaction by mail by including
                  payment for the Shares with the Company's notice to Purchaser.

                           Payment for the Shares may be in the form of cash,
                  the Company's check, a note by the Company (for a term of no
                  longer than eighteen months at an interest rate of eight
                  percent per year), or cancellation of all or a portion of
                  Purchaser's indebtedness to the Company, or any

<PAGE>   15

                  combination thereof. At such closing, the certificate(s)
                  representing the Shares so purchased shall be delivered to the
                  Company and canceled (or the Shares transferred to the
                  Company's assignee, if applicable) or, in the case of payment
                  by the Company (or its assignee) by mail, such certificate(s)
                  shall be deemed canceled (or the Shares transferred to the
                  Company's assignee, if applicable) as of the date of the
                  mailing of the Company's notice, and, thereafter, shall be
                  promptly returned by Purchaser to the Company by certified or
                  registered mail. Shares subject to the Repurchase Option as to
                  which the Company (or its assignee) has not exercised its
                  Repurchase Option within ninety (90) days following
                  Purchaser's Termination shall be released from the Repurchase
                  Option.

                  (c) Certain Definitions. As used in this Agreement, the
         following terms have the following meanings:

                           (i) Commencement Date: ______________, 1998.

                           (ii) "Cause" means (1) the negligent, grossly
                  negligent or willful failure by Purchaser to perform his
                  duties as an employee of the Company or his continued failure
                  to perform duties reasonably requested or reasonably
                  prescribed by the Board of Directors (other than as a result
                  of Purchaser's debt or disability), (2) the engaging by
                  Purchaser in conduct which is materially injurious to the
                  Company or any of its affiliates, (3) negligence, gross
                  negligence or willful misconduct by Purchaser in the
                  performance of his duties which results in, or causes, harm to
                  the Company or any of its affiliates, or (4) Purchaser's
                  commission of a felony or other offense involving moral
                  turpitude.

                  (d) Vested and Unvested Shares. Pursuant to the provisions set
         forth in this paragraph (d) if Purchaser ceases to be employed by the
         Company upon the Termination Date, each share of stock will be deemed
         to be either a share of "Vested Shares" or a share of "Unvested Shares"
         as follows:

                           (i) Founders Stock. The Company will have the right
                  of first refusal to purchase Founder's Stock according to the
                  table below.

                           (ii) Voluntary Termination. If Purchaser ceases to be
                  employed by the Company as a result of Purchaser's voluntary
                  termination, then the percentage set forth below opposite the
                  time period during which the Termination Date occurred of each
                  class of stock will be deemed to be subject to the original
                  repurchase price according to the table below. All other stock
                  will be deemed to be Vested Shares.

<PAGE>   17


                           (iii) Termination for Cause. If Purchaser is no
                  longer employed by the Company as a result of Purchaser's
                  termination for Cause, then Purchaser's shares, except for the
                  initial 52% of Purchaser's shares which vested on the
                  Commencement Date, will be deemed to be "Unvested Shares" and
                  subject to repurchase by the Company at the original Purchase
                  Price. The shares which vested as of the Commencement Date may
                  be purchased at Fair Market Value .

                           (iv) In the event the Company terminates an "at will"
                  employee Purchaser, then the Company has the right to
                  repurchase all shares according to the table above.

                           (v) Notwithstanding anything in this agreement to the
                  contrary, upon an ownership change as defined in Section 6,
                  all of Purchaser's Founder's Stock will be deemed vested
                  shares and may be purchased at Fair Market Value as of the
                  date of the ownership change.

                  (d) Exercise of Unvested Share Purchase Option. The Company
         may exercise the Unvested Share Purchase Option by written notice (the
         "Exercise Notice") delivered to Purchaser or Purchaser's legal
         representative within sixty (60) days after the termination of
         Purchaser's service to the Company. If the Company fails to deliver the
         Exercise Notice within such sixty (60) day period, the Unvested Share
         Purchase Option will terminate unless the Company and Purchaser have
         agreed in writing to extend the time for the exercise of the Unvested
         Share Purchase Option.

                  (e) Payment for Shares. The purchase price per Share
         repurchased by the Company hereunder will be an amount equal to
         Purchaser's original purchase price per share, subject to adjustment
         pursuant to Section 9 hereof (the "Option Price"). Payment by the
         Company to Purchaser will be made, by cash or check, within thirty (30)
         days after the date of the mailing of the Exercise Notice. For purposes
         of the foregoing, cancellation of any indebtedness of Purchaser to the
         Company will be treated as payment to Purchaser in cash to the extent
         of the unpaid principal and any accrued interest canceled.

                  (f) Ownership Change. In the event of an Ownership Change, as
         defined in Section 6 hereof, and notwithstanding anything in this
         agreement to the contrary, all of Purchaser's Founder's Stock will be
         deemed vested shares and may be purchased at Fair Market Value as of
         the date of the ownership change.

                  (g) Transfer of Unvested Shares. Purchaser will not sell,
         pledge or otherwise transfer any Unvested Shares, or any interest
         therein, except pursuant to an exercise of the Unvested Share Purchase
         Option.

         3. Right of First Refusal.

                  (a) Right of First Refusal. In the event Purchaser proposes to
         sell, pledge, or otherwise transfer any Vested Shares (the "Transfer
         Shares") to any person or entity, including, without limitation, any
         shareholder of the Company, the Company will have the right to
         repurchase the Transfer Shares under the terms and subject to the
         conditions set forth in this Section 3 (the "Right of First Refusal").
         For purposes of this Section 3, a change in record ownership of Shares
         will be deemed a transfer subject to the Right of First Refusal whether
         or not such change in record ownership results in a change in the
         beneficial ownership of such Shares.

                  (b) Notice of Proposed Transfer. Prior to any proposed
         transfer of Transfer Shares, Purchaser will give a written notice (the
         "Transfer Notice") to the Company describing fully the proposed
         transfer, including the number of Transfer Shares, the name and address
         of the proposed transferee (the "Proposed Transferee") and, if the
         transfer is voluntary, the proposed transfer price, and containing
         information necessary to show the bona fide nature of the proposed
         transfer. In the event of a bona fide gift or involuntary transfer, the
         proposed transfer price will be deemed to be the Fair Market Value of
         the Transfer Shares as determined by the Company's Board of Directors
         as of the date of the Transfer Notice, subject to Section 5 hereof. In
         the event Purchaser proposes to transfer any Vested Shares to more than
         one Proposed Transferee, Purchaser will provide a separate Transfer
         Notice for the proposed transfer to each Proposed Transferee.

                  (c) Bona Fide Transfer. In the event that the Company
         determines that the information provided by Purchaser in the Transfer
         Notice is insufficient to establish the bona fide nature of a proposed
         voluntary transfer, the Company will give Purchaser written notice of
         Purchaser's failure to comply with the procedure described in this
         Section 3 and Purchaser will have no right to transfer the Transfer
         Shares without first complying with the procedure described in this
         Section 3.

<PAGE>   18

                  (d) Exercise of the Right of First Refusal. In the event the
         proposed transfer is determined by the Company to be bona fide, the
         Company will have the right to purchase all, but not less than all, of
         the Transfer Shares (except as the Company and Purchaser otherwise
         agree) at the purchase price and on the terms set forth in the Transfer
         Notice by delivery to Purchaser of a notice of exercise of the Right of
         First Refusal within thirty (30) days after the date the Transfer
         Notice is delivered to the Company. The Company's exercise or failure
         to exercise the Right of First Refusal with respect to any proposed
         transfer described in a Transfer Notice will not affect the Company's
         right to exercise the Right of First Refusal with respect to any
         proposed transfer described in any other Transfer Notice. If the
         Company exercises the Right of First Refusal, the Company and Purchaser
         will thereupon consummate the sale of the Transfer Shares to the
         Company on the terms set forth in the Transfer Notice within sixty (60)
         days after the date the Transfer Notice is delivered to the Company
         (unless a longer period is offered by the Proposed Transferee);
         provided, however, that in the event the Transfer Notice provides for
         the payment for the Transfer Shares other than in cash, the Company
         will have the option of paying for the Transfer Shares by the
         discounted cash equivalent of the consideration described in the
         Transfer Notice, as reasonably determined by the Company. For purposes
         of the foregoing, cancellation of any indebtedness of Purchaser to the
         Company will be treated as payment to Purchaser in cash to the extent
         of the unpaid principal and any accrued interest canceled.

                  (e) Failure to Exercise the Right of First Refusal. If the
         Company fails to exercise the Right of First Refusal in full within the
         period specified in Section 3(d), Purchaser may conclude a transfer to
         the Proposed Transferee of the Transfer Shares on the terms and
         conditions described in the Transfer Notice, provided such transfer
         occurs not later than ninety (90) days following delivery to the
         Company of the Transfer Notice. The Company will have the right to
         demand further assurances from Purchaser and the Proposed Transferee
         (in a form satisfactory to the Company) that the transfer of the
         Transfer Shares was actually carried out on the terms and conditions
         described in the Transfer Notice. No Transfer Shares will be
         transferred on the books of the Company until the Company has received
         such assurances, if so demanded. Any proposed transfer on terms and
         conditions different from those described in the Transfer Notice, as
         well as any subsequent proposed transfer by Purchaser, will again be
         subject to the Right of First Refusal and will require compliance by
         Purchaser with the procedure described in this Section 3.

                  (f) Transferees of the Transfer Shares. All transferees of the
         Transfer Shares or any interest therein, other than the Company, will
         be required as a condition of such transfer to agree in writing (in a
         form satisfactory to the Company) that such transferee will receive and
         hold such Transfer Shares or interests subject to the provisions of
         this Section 3 providing for the Right of First Refusal with respect to
         any subsequent transfer. Any sale or transfer of any Shares will be
         void unless the provisions of this Section 3 are complied with.

                  (g) Transfers Not Subject to the Right of First Refusal. The
         Right of First Refusal will not apply to any transfer of Vested Shares
         to Purchaser's estate, members of Purchaser's family or trusts for the
         benefit of Purchaser or any member of Purchaser's family, provided that
         in each case the proposed transferee agrees in writing (in a form
         satisfactory to the Company) that such transferee will receive and hold
         such Vested Shares subject to the provisions of this Section 3
         providing for the Right of First Refusal with respect to any subsequent
         transfer. Neither will the Right of First Refusal apply to any transfer
         or exchange of the Shares if such transfer or exchange is in connection
         with an Ownership Change, as defined in Section 6 hereof. If the
         consideration received pursuant to such transfer or exchange consists
         of securities, such securities will remain subject to the Right of
         First Refusal unless the provisions of Section 3(h) result in a
         termination of the Right of First Refusal.

                  (h) Early Termination of the Right of First Refusal. The other
         provisions of this Section 3 notwithstanding, the Right of First
         Refusal will terminate, and be of no further force and effect, upon

                           (i) the occurrence of a Transfer of Control, as
                  defined in Section 6 hereof, or

                           (ii) the existence of a public market for the class
                  of securities subject to the Right of First Refusal (including
                  any securities issued in exchange for any Shares). A "public
                  market" will be deemed to exist if such securities are (1)
                  listed on a national securities exchange (as that term is used
                  in the Securities Exchange Act of 1934, as amended (the
                  "Exchange Act") or (2) traded in the over-the-counter market
                  and prices therefor are published daily on business days in a
                  recognized financial journal.

<PAGE>   19



         4. Spousal Consent. If Purchaser is married on the date of this
Agreement, Purchaser's spouse will execute a Consent of Spouse in the form of
Exhibit A hereto, effective on the date hereof. Such consent will not be deemed
to confer or convey to the spouse any rights in the Shares that do not otherwise
exist by operation of law or the agreement of the parties. If Purchaser should
marry or remarry subsequent to the date of this Agreement, Purchaser will within
thirty (30) days thereafter obtain his or her new spouse's acknowledgment of and
consent to the existence and binding effect of all restrictions contained in
this Agreement by signing an additional Consent of Spouse in the form of Exhibit
A. Failure to provide an additional Consent of Spouse will be treated as a
transfer of all of Purchaser's Shares to such spouse and trigger the Company's
Right of First Refusal under Section 3 above.

         5. Appraisal. In the case of the Company's exercise of its Right of
First Refusal pursuant to Section 3 hereof with respect to a bona fide gift or
involuntary transfer referred to therein, if Purchaser disagrees with the
valuation determined by the Company's Board of Directors, Purchaser may, by
giving written notice to the Company within ten (10) days after being informed
of such valuation, request that the value of the Shares at issue be determined
by an independent appraiser to be selected by the Company. The Company will
select an appraiser to determine the value of such Shares within fifteen (15)
days after the Company's actual receipt of Purchaser's notice disputing the
valuation set by the Company's Board of Directors. Such appraiser will be
subject to the approval of Purchaser, which approval will not be unreasonably
withheld or delayed. Purchaser's approval or refusal to approve the appraiser
must be given before the appraiser announces a valuation. The value of such
Shares, as determined by the appraiser, will be conclusively binding on all of
the parties concerned. The expenses of appraisal will be borne equally by the
Company and Purchaser. Any time required to resolve a valuation dispute will be
added to the time period in which the Company may exercise its Right of First
Refusal under Section 3 hereof.

         6. Ownership Change and Transfer of Control. An "Ownership Change" will
be deemed to have occurred if any of the following events occur with respect to
the Company:

                  (a) the direct or indirect sale or exchange by the
         shareholders of the Company of all or substantially all of the capital
         stock of the Company;

                  (b) a merger or consolidation in which the Company is a party;

                  (c) the sale, exchange, or transfer of all or substantially
         all of the assets of the Company (other than a sale, exchange, or
         transfer to one or more subsidiary corporations [as defined in section
         424(f) of the Internal Revenue Code of 1986, as amended (the "Code")]
         of the Company); or

                  (d) a liquidation or dissolution of the Company.

                  A "Transfer of Control" shall mean an Ownership Change in
         which the shareholders of the Company immediately before such Ownership
         Change do not retain, directly or indirectly, at least a majority of
         the beneficial interest in the voting stock or securities of the
         Company or any successor entity thereto immediately after such
         transaction.

         7. At-Will Employment. Unless specifically provided in another written
agreement signed by Purchaser and an executive officer of the Company (or
another executive officer of the Company if Purchaser is an executive officer of
the Company), any employment of Purchaser by the Company is not for any definite
period of time, is at-will, and may be terminated at any time, with or without
cause, by Purchaser or by the Company. Nothing in this Agreement is intended to
change the nature of any such employment relationship.

         8. Assignment of Rights. The Company may assign its rights under
Section 2 or 3 hereof at any time, whether or not any event has occurred which
permits the Company to exercise such rights, to one or more persons, including
shareholders of the Company, who will have the right to so exercise such rights
in his, her or their own names and for his, her or their own account. If the
exercise of any such right requires the consent of the Delaware Commissioner of
Corporations, the parties agree to cooperate in requesting such consent.

         9. Adjustment to Shares Subject to Company's Rights. If, from time to
time during the term of this Agreement, there is any stock dividend or
liquidating dividend of cash and/or property, stock split, reverse stock split,
recapitalization, reclassification or other similar change in the character or
amount of any of the outstanding

                                  CONFIDENTIAL                      Page 6 of 18
<PAGE>   20

securities of the Company, then, in such event any and all new, substituted or
additional securities or other property to which Purchaser is entitled by reason
of his or her ownership of the Shares will be immediately subject to the
provisions of this Agreement on the same basis as all Shares originally
purchased hereunder, and will be included in the word "Shares" for all purposes
of this Agreement with the same force and effect as the Shares presently subject
to this Agreement. For purposes of Sections 2 and 3 hereof, while the total
price payable to exercise the rights provided in such sections will remain the
same after each such event, the price payable per share to exercise such rights
will be appropriately adjusted.

         10. Initial Public Offering. Purchaser hereby agrees that in the event
of an initial underwritten public offering of securities (an "IPO") made by the
Company pursuant to an effective registration statement filed under the
Securities Act of 1933, as amended (the "Securities Act"), Purchaser will not
offer, sell, contract to sell, pledge, hypothecate, grant any option to purchase
or make any short sale of, or otherwise dispose of any securities of the Company
or any rights to acquire securities of the Company for such period of time from
and after the effective date of such registration statement as may be designated
by the managing underwriter(s) for the IPO; provided, however, that such period
of time will not exceed one hundred eighty (180) days from the effective date of
such registration statement. At the Company's request, Purchaser shall execute
and deliver to such managing underwriter(s) an agreement, in customary form,
confirming Purchaser's obligations under this Section 10. The foregoing
restriction will not apply to securities registered in the IPO. Purchaser shall
be subject to the foregoing restriction only if all officers and directors of
the Company are also subject to similar arrangements.

         11. Legends. All certificates representing any Shares subject to the
provisions of this Agreement will bear the following legends:

                  (a) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
         TRANSFER RESTRICTIONS IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT
         BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR HIS OR HER
         PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL
         OFFICE OF THE COMPANY.

                  (b) THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
         A RIGHT OF FIRST REFUSAL OPTION IN FAVOR OF THE COMPANY OR ITS ASSIGNEE
         SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED
         HOLDER, OR HIS OR HER PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON
         FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

                  (c) THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
         SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN
         EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH
         SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701
         UNDER SUCH ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE
         HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE COMPANY,
         STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT
         FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

                  (d) Any legend required under applicable state securities
         laws.

         12. Purchaser Representations and Warranties. In connection with the
proposed purchase of the Shares, Purchaser hereby agrees, represents and
warrants as follows:

                  (a) Investment Intent. Purchaser is purchasing the Shares
         solely for Purchaser's own account for investment and not with a view
         to, or for resale in connection with, any distribution thereof within
         the meaning of the Securities Act. Purchaser does not have any present
         intention of selling, offering to sell or otherwise disposing of or
         distributing the Shares or any portion thereof; and the entire legal
         and beneficial interest of the Shares Purchaser is acquiring is being
         purchased for, and will be held for the account of, Purchaser only and
         neither in whole nor in part for any other person.

<PAGE>   21

                  (b) Information Concerning the Company. Purchaser is aware of
         the Company's business affairs and financial condition and has acquired
         sufficient information about the Company to reach an informed and
         knowledgeable decision to acquire the Shares. Purchaser further
         represents and warrants that Purchaser has discussed the Company and
         its plans, operations and financial condition with its officers, has
         received all such information as Purchaser deems necessary and
         appropriate to enable Purchaser to evaluate the financial risk inherent
         in making an investment in the Shares and has received satisfactory and
         complete information concerning the business and financial condition
         and prospects of the Company in response to all inquiries in respect
         thereof.

                  (c) Economic Risk. Purchaser realizes that the purchase of the
         Shares will be a highly speculative investment, and Purchaser is able,
         without impairing his or her financial condition, to hold the Shares
         for an indefinite period of time and to suffer a complete loss of
         Purchaser's investment in the Shares.

                  (d) Restricted Securities. Purchaser understands and
         acknowledges that:

                           (i) The sale of the Shares has not been registered
                  under the Securities Act, and the Shares must be held
                  indefinitely unless a transfer of the Shares is subsequently
                  registered under the Securities Act or an exemption from such
                  registration is available, and that the Company is under no
                  obligation to register the Shares; and

                           (ii) The Company will make a notation in its records
                  of the aforementioned restrictions on transfer and legends.

                  (e) Rule 144. Purchaser is aware of the provisions of Rule
         144, promulgated under the Securities Act, which, in substance, permit
         limited public resale of "restricted securities" acquired, directly or
         indirectly, from the issuer thereof (or an affiliate of such issuer),
         in a nonpublic offering subject to the satisfaction of certain
         conditions, including among other things: the resale occurring not less
         than one year from the date Purchaser has purchased and paid for the
         Shares; the availability of certain public information concerning the
         Company; the sale being made through a broker in an unsolicited
         "broker's transaction" or in a transaction directly with a market maker
         (as said term is defined under the Exchange Act); and that any sale of
         the Shares may be made by him or her only in limited amounts during any
         three-month period. Purchaser understands that at the time Purchaser
         wishes to sell the Shares there may be no public market upon which to
         make such a sale, and that, even if such a public market then exists,
         the Company may not then be satisfying the current public information
         requirements of Rule 144, and that, in such event, Purchaser would be
         precluded from selling the Shares under Rule 144 even if the one-year
         minimum holding period has been satisfied. Purchaser understands that
         in the event all of the requirements of Rule 144 are not satisfied,
         registration under the Securities Act or compliance with another
         exemption from such registration will be required; and that,
         notwithstanding the fact that Rule 144 is not exclusive, the Staff of
         the SEC has expressed its opinion that persons proposing to sell
         restricted securities other than in a registered offering or pursuant
         to Rule 144 will have a substantial burden of proof in establishing
         that an exemption from registration is available for such offers or
         sales, and that such persons and their respective brokers who
         participate in such transactions do so at their own risk.

                  (f) Further Limitations on Disposition. Purchaser further
         agrees that Purchaser will in no event make any disposition of all or
         any portion of the Shares unless:

                           (i) There is then in effect a registration statement
                  under the Securities Act covering such proposed disposition
                  and such disposition is made in accordance with said
                  registration statement; or

                           (ii) Purchaser has notified the Company of the
                  proposed disposition and furnished the Company with a detailed
                  statement of the circumstances surrounding the proposed
                  disposition, and Purchaser has furnished the Company with an
                  opinion of Purchaser's own counsel to the effect that such
                  disposition will not require registration of such shares under
                  the Securities Act, and such opinion of Purchaser's counsel
                  has been concurred in by counsel for the Company.

<PAGE>   22





                  (g) Capacity to Protect Interests. Purchaser has (i) a
         preexisting personal or business relationship with the Company or one
         or more of its officers, directors, or controlling persons, consisting
         of personal or business contacts of a nature and duration to enable
         Purchaser to be aware of the character, business acumen and general
         business and financial circumstances of the person with whom such
         relationship exists, or (ii) such knowledge and experience in financial
         and business matters as to make Purchaser capable of evaluating the
         merits and risks of an investment in the Shares and to protect
         Purchaser's own interests in the transaction, or (iii) both such
         relationship and such knowledge and experience.

                  (h) No Qualification. Purchaser understands that the Shares
         have not been qualified under General Corporation Law. Purchaser
         understands that the Company is relying on Purchaser's representations
         and warrants that the Company is entitled to rely on such
         representations and that such reliance is reasonable.

         13. Escrow and Transfer Restrictions.

                  (a) Escrow. As security for Purchaser's faithful performance
         of the terms of this Agreement and to ensure the availability for
         delivery of Purchaser's Shares upon exercise of either the Unvested
         Share Purchase Option or the Share Purchase Option, Purchaser agrees to
         deliver to and deposit with the Company's legal counsel, Robert D.
         Baker, Attorney at Law (the "Escrow Agent"), as Escrow Agent, two
         originals of an Assignment Separate From Certificate duly endorsed
         (with date and number of shares blank) in the form attached hereto as
         Exhibit B, together with the certificate or certificates evidencing the
         Shares; said documents are to be held by the Escrow Agent pursuant to
         the Joint Escrow Instructions of the Company and Purchaser set forth in
         Exhibit C attached hereto and incorporated by this reference, which
         instructions will also be delivered to the Escrow Agent at the closing
         hereunder.

                  (b) Rights as Shareholder. Purchaser will, during the term of
         this Agreement, exercise all rights and privileges of a shareholder of
         the Company with respect to the Shares deposited in said escrow, except
         that Purchaser will not sell, transfer, pledge, hypothecate or
         otherwise dispose of any Shares except in accordance with the terms of
         this Agreement.

                  (c) Transfers in Violation of Agreement. The Company will not
         be required to (i) transfer on its books any Shares which are sold or
         transferred in violation of any of the provisions of this Agreement or
         (ii) treat as owner of such Shares, or to accord the right to vote as
         such owner or to pay dividends to, any transferee to whom such Shares
         are so transferred.

         14. Tax Matters.

                  (a) Valuation of Shares. Purchaser understands that:

                           (i) The Shares have been valued by the Company, and
                  the Company believes such valuation represents a fair attempt
                  at reaching an accurate appraisal of their worth; Purchaser
                  understands, however, that the Company can give no assurances
                  that the Internal Revenue Service ("IRS") will not assert that
                  the value of the Shares on the date of purchase is greater
                  than so determined.

                           (ii) If the IRS were to succeed in a tax
                  determination under the Internal Revenue Service Code of 1986,
                  as amended (the "Code") that the Shares have value greater
                  than that upon which this transaction was based, the
                  additional value would constitute ordinary income as of the
                  date of its receipt. The additional taxes (and interest) due
                  would be payable by Purchaser, and there is no provision for
                  the Company to reimburse him or her for such tax liability,
                  and Purchaser assumes all responsibility for such potential
                  tax liability. The Company undertakes no obligation to inform
                  Purchaser of any change in the tax laws which may affect this
                  Agreement or its consequences.

<PAGE>   23


                           (iii) The Company would be entitled to the benefit,
                  in any such transaction, if a determination were made prior to
                  the three (3) year statute of limitations period affecting the
                  Company, of an increase in its deduction for the excess amount
                  deemed paid, which would offset its operating profits, or, if
                  not profitable, would create a net operating loss carry
                  forward arising from operations in that year.

                  (b) Election Under Section 83(b) of the Code.

                           (i) Purchaser understands that Section 83 of the Code
                  taxes as ordinary income the difference between the amount
                  paid for the Shares and the Fair Market Value of the Shares as
                  of the date any restrictions on the Shares lapse. In this
                  context, "restriction" means the right of the Company to buy
                  back the stock pursuant to the Unvested Share Repurchase
                  Option contained in this Agreement. In the event the Company
                  has registered its securities under the Exchange Act,
                  "restriction" with respect to officers, directors and greater
                  than 10% shareholders also means the six (6) month period
                  after the closing during which such officers, directors and
                  greater than 10% shareholders are subject to suit under
                  Section 16(b) of the Exchange Act. Purchaser understands that
                  he or she may elect to be taxed at the time the Shares are
                  purchased rather than when and as the Unvested Share
                  Repurchase Option or six (6) month Section 16(b) period
                  expires by filing an election under Section 83(b) of the Code
                  with the IRS within thirty (30) days from the date of
                  purchase. Even if the Fair Market Value of the Shares equals
                  the amount paid for the Shares, the election must be made to
                  avoid adverse tax consequences in the future. The form for
                  making this election is attached as Exhibit D hereto.
                  Purchaser understands that failure to make this filing timely
                  will result in the recognition of ordinary income by
                  Purchaser, as the Unvested Share Repurchase Option lapses, or
                  after the lapse of the six (6) month Section 16(b) period, on
                  the difference between the purchase price and the Fair Market
                  Value of the Shares at the time such restrictions lapse.

                           (ii) Purchaser understands that he or she should
                  consult with the his or her tax advisor regarding the
                  advisability of filing with the IRS an election under Section
                  83(b) of the Code, which must be filed no later than thirty
                  (30) days after the date of this Agreement. Failure to file an
                  election under Section 83(b), if appropriate, may result in
                  adverse tax consequences to Purchaser. Purchaser acknowledges
                  that he or she has been advised to consult with a tax advisor
                  regarding the tax consequences to Purchaser of the purchase of
                  Shares hereunder. AN ELECTION UNDER SECTION 83(b) MUST BE
                  FILED WITHIN 30 DAYS AFTER THE DATE ON WHICH PURCHASER
                  PURCHASES THE SHARES. THIS TIME PERIOD CANNOT BE EXTENDED.
                  PURCHASER ACKNOWLEDGES THAT TIMELY FILING OF A SECTION 83(b)
                  ELECTION IS PURCHASER'S SOLE RESPONSIBILITY, EVEN IF PURCHASER
                  REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO FILE SUCH
                  ELECTION ON HIS OR HER BEHALF.

         15. Miscellaneous.

                  (a) Future Instruments. The parties agree to execute such
         further instruments and to take such further action as may reasonably
         be necessary to carry out the intent of this Agreement.

                  (b) Notice. Any notice required or permitted hereunder will be
         given in writing and will be deemed effectively given upon personal
         delivery or upon deposit in the United States Post Office, by
         registered or certified mail with postage and fees prepaid, addressed
         to the other party hereto at the address shown below that party's
         signature or at such other address as such party may designate by ten
         (10) days' advance written notice to the other party hereto.

                  (c) Successors and Assigns. This Agreement will inure to the
         benefit of the successors and assigns of the Company and, subject to
         the restrictions on transfer herein set forth, be binding upon
         Purchaser and Purchaser's heirs, executors, administrators, successors
         and assigns; provided, however, that Purchaser may not assign his or
         her rights under this Agreement without the Company's prior written
         consent.

<PAGE>   24



                  (d) Entire Agreement; Applicable Law. This Agreement, together
         with the exhibits hereto, will be construed under the laws of the State
         of Colorado other than the conflict of laws and except for matters of
         corporate governance which shall be governed by and construed according
         to the laws of the State of Delaware, and constitutes the entire
         agreement of the parties with respect to the subject matter hereof,
         superseding all prior written or oral agreements, and no amendment or
         addition hereto will be deemed effective unless agreed to in writing by
         the parties hereto.

                  (e) Right to Specific Performance. Purchaser agrees that the
         Company will be entitled to a decree of specific performance of the
         terms hereof or an injunction restraining violation of this Agreement,
         said right to be in addition to any other remedies available to the
         Company.

                  (f) Delays. No failure on the part of any party to exercise or
         delay in exercising any right hereunder will be deemed a waiver
         thereof, nor will any such failure or delay, or any single or partial
         exercise of any such right, preclude any further or other exercise of
         such right or any other right.

                  (g) Partial Invalidity. If any provision of this Agreement, or
         the application thereof, is for any reason and to any extent determined
         by a court of competent jurisdiction to be invalid or unenforceable,
         the remainder of this Agreement and the application of such provision
         to other persons or circumstances will be interpreted so as best to
         reasonably effect the intent of the parties hereto. The parties agree
         to use their best efforts to replace such void or unenforceable
         provision of this Agreement with a valid and enforceable provision
         which will achieve, to the extent greatest possible, the economic,
         business and other purposes of the void or unenforceable provision.

                  (h) Counterparts. This Agreement may be executed in
         counterparts, each of which will be an original and all of which
         together will constitute one and the same agreement.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the day and year first above written.

Dear Sir:

         As Escrow Agent for both CHAPARRAL TECHNOLOGIES, INC., a Delaware
corporation (the "Company"), and the undersigned purchaser ("Purchaser") of
Common Stock of the Company (the "Shares"), you are hereby authorized and
directed to hold the documents delivered to you pursuant to the terms of that
certain Founder Stock Purchase Agreement (the "Agreement"), dated as of the date
hereof, to which a copy of these Joint Escrow Instructions is attached as
Exhibit C, in accordance with the following instructions:

         1. In the event the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the "Company") shall elect
to exercise the Unvested Share Purchase Option as defined in the Agreement, the
Company will give to Purchaser and you a written notice specifying the number of
Shares to be purchased, the purchase price, and the time of the closing
hereunder at the principal office of the Company. Purchaser and the Company
hereby irrevocably authorize and direct you to close the transaction
contemplated by such notice in accordance with the terms of said notice.

         2. At the closing, you are directed to (a) date the stock assignments
necessary for the transfer in question, (b) fill in the number of Shares being
transferred, and (c) deliver same, together with the certificates evidencing the
Shares to be transferred, to the Company against the simultaneous delivery to
you of the purchase price (by check or evidence of cancellation of indebtedness
of Purchaser to the Company) for the number of Shares being purchased pursuant
to the exercise of the Unvested Share Purchase Option.

         3. Purchaser irrevocably authorizes the Company to deposit with you any
certificates evidencing Shares to be held by you hereunder and any additions and
substitutions to said Shares as defined in the Agreement. Purchaser does hereby
irrevocably constitute and appoint you as his or her attorney-in-fact and agent
for the term of this escrow to execute with respect to such securities all stock
certificates, stock assignments, or other documents necessary or appropriate to
make such securities negotiable and complete any transaction herein
contemplated. Subject to the provisions of this Paragraph and the transfer
restrictions set forth in the Agreement, Purchaser will exercise all rights and
privileges of a shareholder of the Company while the Shares are held by you.

         4. This escrow will terminate at such time as there are no longer any
Shares subject to the Unvested Share Purchase Option.

         5. If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Purchaser,
you will deliver all of same to Purchaser and will be discharged of all further
obligations hereunder.

         6. Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

         7. You will be obligated only for the performance of such duties as are
specifically set forth herein and may rely and will be protected in relying or
refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties. You
will not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Purchaser while acting in good faith and
in the exercise of your own good judgment, and any act done or omitted by you
pursuant to the advice of your own attorneys will be conclusive evidence to such
good faith.

         8. You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law, and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case you obey or comply with any such order, judgment or decree of any

set aside, vacated or found to have been entered without jurisdiction.

         9. You will not be liable in any respect on account of the identities,
authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

as you may deem necessary or proper to advise you in connection with your
obligations hereunder, may rely upon the advice of such counsel, and may pay
such counsel reasonable compensation therefor.

         12. Your responsibilities as Escrow Agent hereunder will terminate if
you will resign by written notice to each party. In the event of any such
termination, the Company will appoint a successor Escrow Agent.

         13. If you reasonably require other or further instructions in
connection with these Joint Escrow Instructions or obligations in respect
hereto, the necessary parties hereto will join in furnishing such instruments.

         14. It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or rights of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such dispute will have been settled either by mutual written agreement of
the parties concerned or by a final order, decree, or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you will be under no duty whatsoever to institute or defend
any such proceedings.

and will be deemed effectively given upon personal delivery or upon deposit in

Agreement in the form attached to this Agreement as Exhibit D or an employment

            3.9 Status of Proprietary Assets.

                (a) Ownership. The Company has full title and ownership of, or
has license to, all patents, patent applications, trademarks, service marks,
trade names, copyrights, moral rights, mask works, trade secrets, confidential
and proprietary information, compositions of matter, formulas, designs,
proprietary rights, know-how and processes (all of the foregoing collectively
hereinafter referred to as the "Proprietary Assets") necessary to enable it to
carry on its business as now conducted and as presently proposed to be
conducted, without any conflict with or infringement of the rights of others. To
the best of the Company's knowledge, no third party has any ownership right,
title, interest, claim in or lien on any of the Company's Proprietary Assets and
the Company has taken, and in the future the Company will use its best efforts
to take, all steps reasonably necessary to preserve its legal rights in, and the
secrecy of, all its Proprietary Assets, except those for which disclosure is
required for legitimate business or legal reasons.

                (b) Licenses; Other Agreements. The Company has not granted,

agreement of any kind with respect to any of its Proprietary Assets. The Company

                (d) No Breach by Employee. The Company is not aware that any
employee or consultant of the Company is obligated under any agreement
(including licenses, covenants or commitments of any nature) or subject to any
judgment, decree or order of any court or administrative agency, or any other
restriction that would interfere with the use of his or her best efforts to
carry out his or her duties for the Company or to promote the interests of the
Company or that would conflict with the Company's business as proposed to be
conducted. The carrying on of the Company's business by the employees and
contractors of the Company and the conduct of the Company's business as
presently proposed, will not, to the best of the Company's knowledge, conflict
with or result in a breach of the terms, conditions or provisions of, or
constitute a default under, any contract, covenant or instrument under which any
of such employees or contractors or the Company is now obligated. The Company
does not believe it is or will be necessary to utilize any inventions of any
employees of the Company (or persons the Company currently intends to hire) made
prior to their employment by the Company. At no time during the conception of or
reduction of any of the Company's Proprietary Assets to practice was any
developer, inventor or other contributor to such patents operating under any
grants from any governmental entity or agency or private source, performing
research sponsored by any governmental entity or agency or private source or
subject to any employment agreement or invention assignment or nondisclosure
agreement or other obligation with any third party that could adversely affect
the Company's rights in such Proprietary Assets.

            3.10 Compliance with Law and Charter Documents. The Company is not
in violation or default of any provisions of its Certificate of Incorporation or
Bylaws, both as amended, and to the best of the Company's knowledge, except for
any violations that individually and in the aggregate would have no material
adverse impact on the Company's business, the Company is in compliance with all
applicable statutes, laws, regulations and executive orders of the United States
of America and all states, foreign countries or other governmental bodies and
agencies having jurisdiction over the Company's business or properties. The
Company has not received any notice of any violation of such statutes, laws,
regulations or orders which has not been remedied prior to the date hereof. The
execution, delivery and performance of this Agreement, and the execution,
delivery, and performance of the Stockholder Rights Agreement and the Co-Sale
Agreement, when entered into, and the consummation of the transactions
contemplated hereby or thereby will not result in any such violation or default,
or be in conflict with or constitute, with or without the passage of time or the
giving of notice or both, either a default under the Company's Certificate of
Incorporation or Bylaws, or any agreement or contract of the Company, or, to the
best of the Company's knowledge, a violation of any statutes, laws, regulations
or orders, or an event which results in the creation of any lien, charge or
encumbrance upon any asset of the Company.

            3.11 Material Agreements.

                (a) List of Material Agreements. Attached to this Agreement as
Exhibit E is a complete list of all agreements, contracts, leases, licenses,
instruments and commitments (oral or written) to which the Company is a party or
is bound that, individually or in the aggregate, are material to the business,
properties, financial condition, results of operation, affairs or prospects of
the Company ("Material Agreements"); provided that for purposes of this Section
3.11 only, no agreement under which the only remaining obligation of the Company
is to make a payment of money in the amount of $5,000 or less will be deemed to
be material to its business, properties, financial condition or results of
operations if the failure to make such payment will not result in the loss by
the Company of any rights that are material to the conduct of its business.

                (b) No Breach. The Company has not breached, nor does the
Company have any knowledge of any claim or threat that the Company has breached,
any term or condition of (i) any Material Agreement set forth in Exhibit E, or
(ii) any other agreement, contract, lease, license, instrument or commitment
that, individually or in the aggregate, would have a material adverse effect on
the business, properties, financial condition, results of operations or affairs
or prospects of the Company. Each Material Agreement set forth in Exhibit E is
in full force and effect, is enforceable against each of the parties thereto,
and, to the Company's knowledge, no other party to such Material Agreement is in
default thereunder. The Company is not a party to any agreement that restricts
its ability to market or sell any of its products (whether by territorial
restriction or otherwise).

            3.12 Registration Rights. Except as will be provided in the
Stockholder Rights Agreement, the Company has not granted or agreed to grant to
any person or entity any rights (including piggyback registration rights) to

party other than the lessors of such property and assets.

         4. REPRESENTATIONS, WARRANTIES AND CERTAIN AGREEMENTS OF PURCHASER.
Purchaser hereby represents and warrants to, and agrees with, the Company that:

            4.1 Authorization. This Agreement constitutes Purchaser' valid and
legally binding obligation, enforceable in accordance with its terms except as
may be limited by (a) applicable bankruptcy, insolvency, reorganization or other
laws of general application relating to or affecting the enforcement of
creditors' rights generally and (b) the effect of rules of law governing the
availability of equitable remedies. Purchaser represents that he has full power
and authority to enter into this Agreement, the Stockholder Rights Agreement,
and the Co-Sale Agreement.

            4.2 Purchase for Own Account. The Purchased Shares to be purchased
by Purchaser hereunder will be acquired for investment for Purchaser' own
account, not as a nominee or agent, and not with a view to the public resale or
distribution thereof within the meaning of the 1933 Act, and Purchaser has no
present intention of selling, granting any participation in, or otherwise
distributing the same.

            4.3 Disclosure of Information. Purchaser has received or has had
full access to all the information he considers necessary or appropriate to make
an informed investment decision with respect to the Purchased Shares to be
purchased by Purchaser under this Agreement. Purchaser further has had an
opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of the offering of the Purchased Shares and to obtain
additional information (to the extent the Company possessed such information or
could acquire it without unreasonable effort or expense) necessary to verify any
information furnished to Purchaser or to which Purchaser had access. The
foregoing, however, does not in any way limit or modify the representations and
warranties made by the Company in Section 3.

            4.4 Investment Experience. Purchaser understands that the purchase
of the Purchased Shares involves substantial risk. Purchaser: (a) has experience
as an investor in securities of companies in the development stage and
acknowledges that it is able to fend for himself, can bear the economic risk of
its investment in the Purchased Shares and has such knowledge and experience in
financial or business matters that he is capable of evaluating the merits and
risks of this investment in the Purchased Shares and protecting its own
interests in connection with this investment and/or (b) has a preexisting
personal or business relationship with the Company and certain of its officers,
directors or controlling persons of a nature and duration that enables it to be
aware of the character, business acumen and financial circumstances of such
persons.

            4.5 Accredited Investor Status. Purchaser is an "accredited
investor" within the meaning of Regulation D promulgated under the 1933 Act.

            4.6 Restricted Securities. Purchaser understands that the Purchased
Shares are characterized as "restricted securities" under the 1933 Act inasmuch
as they are being acquired from the Company in a transaction not involving a
public offering and that under the 1933 Act and applicable regulations
thereunder such securities may be resold without registration under the 1933 Act
only in certain limited circumstances. In this connection, Purchaser represents
that he is familiar with Rule 144 of the SEC, as presently in effect, and
understands the resale limitations imposed thereby and by the 1933 Act.
Purchaser understands that the Company is under no obligation to register any of
the securities sold hereunder except as will be provided


Preferred A.doc (Rev. 3/31/99)    CONFIDENTIAL                      Page 6 of 11
<PAGE>   7

in the Investors' Rights Agreement. Purchaser understands that no public market
now exists or is likely to exist for any of the Purchased Shares and that it is
uncertain whether a public market will ever exist for the Conversion Shares.

            4.7 Further Limitations on Disposition. Without in any way limiting
the representations set forth above, Purchaser further agrees not to make any
disposition of all or any portion of the Purchased Shares or the Conversion
Shares unless and until:

                (a) There is then in effect a registration statement under the
1933 Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

                (b) (i) Purchaser shall have notified the Company of the
proposed disposition and shall have furnished the Company with a statement of
the circumstances surrounding the proposed disposition, and (ii) Purchaser shall
have furnished the Company, at the expense of Purchaser or his transferee, with
an opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of such securities under the 1933 Act.

         Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be required: (i) for any
transfer of any Purchased Shares or Conversion Shares in compliance with SEC
Rule 144 or Rule 144A; or (ii) for any transfer of any Purchased Shares or
Conversion Shares by Purchaser to (A) a partner of Purchaser, or (B) the estate
of any such partner, or (iii) for the transfer by gift to any trust for any of
the foregoing or for the benefit of any family member of Purchaser, or (iv) to
any entity controlled by Purchaser or any member of Purchaser; provided that in
each of the foregoing cases the transferee agrees in writing to be subject to
the terms of this Section 4 (other than Section 4.5) to the same extent as if
the transferee were Purchaser hereunder.

            4.8 Legends. It is understood that the certificates evidencing the
Purchased Shares and the Conversion Shares will bear the legends set forth
below:

                (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE
SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS
ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS
PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO
REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE
REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD
OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN
FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED
TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE
SECURITIES LAWS.

                (b) Any legend required by the Law or by the laws of the State
of Delaware, including a legend substantially in the form of the following:

                THE SHARES EVIDENCED BY THIS CERTIFICATE: (1) ARE CONVERTIBLE
INTO SHARES OF COMMON STOCK OF THE COMPANY AT THE OPTION OF THE HOLDER AT ANY
TIME PRIOR TO AUTOMATIC CONVERSION THEREOF; AND (2) AUTOMATICALLY CONVERT INTO
COMMON STOCK OF THE COMPANY IN THE EVENT OF A PUBLIC OFFERING MEETING CERTAIN
REQUIREMENTS OR UPON CERTAIN CONSENTS OF THE HOLDERS OF THE COMPANY'S PREFERRED
STOCK; ALL PURSUANT TO AND UPON THE TERMS AND CONDITIONS SPECIFIED IN THE
COMPANY'S CERTIFICATE OF INCORPORATION. A COPY OF SUCH CERTIFICATE OF
INCORPORATION MAY BE OBTAINED, WITHOUT CHARGE, AT THE COMPANY'S PRINCIPAL
OFFICE.

                The legend set forth in (a) above shall be removed by the
Company from any certificate evidencing Purchased Shares or Conversion Shares
upon delivery to the Company of an opinion by counsel, reasonably satisfactory
to the Company, that a registration statement under the 1933 Act is at that time
in effect with respect to the legended security or that such security can be
freely transferred in a public sale without such a registration statement being
in effect and that such transfer will not jeopardize the exemption or exemptions
from registration pursuant to which the Company issued the Purchased Shares or
Conversion Shares. The Company will not require options of counsel for
transactions made pursuant to Rule 144 except in unusual circumstances.

         5. CONDITIONS TO PURCHASER' OBLIGATIONS AT THE CLOSING. The obligations
of Purchaser under Section 2 of this Agreement are subject to the fulfillment or

                (a) Ownership. The Company has full title and ownership of, or
has license to, all patents, patent applications, trademarks, service marks,
trade names, copyrights, moral rights, mask works, trade secrets, confidential
and proprietary information, compositions of matter, formulas, designs,
proprietary rights, know-how and processes (all of the foregoing collectively
hereinafter referred to as the "Proprietary Assets") necessary to enable it to
carry on its business as now conducted and as presently proposed to be
conducted, without any conflict with or infringement of the rights of others. No
third party has any ownership right, title, interest, claim in or lien on any of
the Company's Proprietary Assets and the Company has taken, and in the future
the Company will use its best efforts to take, all steps reasonably necessary to
preserve its legal rights in, and the secrecy of all its Proprietary Assets,
except those for which disclosure is required for legitimate business or legal
reasons.

payments to third parties with respect to the marketing, sale, distribution,

other person or entity.

                (d) No Employee Breach. The Company is not aware that any
employee or consultant of the Company is obligated under any agreement
(including licenses, covenants or commitments of any nature) or subject to any
judgment, decree or order of any court or administrative agency, or any other
restriction that would interfere with the use of his or her best efforts to
carry out his or her duties for the Company, promote the interests of the
Company, or conflicts with the Company's business as proposed to be conducted.
The carrying on of the Company's business by the employees and contractors of
the Company and the conduct of the Company's business as presently proposed,
will not, to the best of the Company's knowledge, conflict with or result in a
breach of the terms, conditions or provisions of, or constitute a default under,
any contract, covenant or instrument under which any of such employees or
contractors or the Company is now obligated. The Company does not believe it is
or will be necessary to utilize any inventions of any employees of the Company
(or persons the Company currently intends to hire) made prior to their
employment by the Company. At no time during the conception of or reduction of
any of the Company's Proprietary Assets to practice was any developer, inventor
or other contributor to such patents operating under any grants from any
governmental entity or agency or private source, performing research sponsored
by any governmental entity or agency or private source or subject to any
employment agreement or




                                       5

Assets.

of the United States of America and all states, foreign countries or other
governmental bodies and agencies having jurisdiction over the Company's business
or properties. The Company has not received any notice of any violation of such
statutes, laws, regulations or orders, which has not been remedied prior to the
date hereof. The execution, delivery and performance of this Agreement and the
Investors' Rights Agreement, when entered into, and the consummation of the
transactions contemplated hereby or thereby, will not result in any such
violation or default, or be in conflict with or constitute, with or without the
passage of time or the giving of notice or both, either a default under the
Company's Certificate of Incorporation or Bylaws, or any agreement or contract
of the Company, or, to the best of the Company's knowledge, a violation of any
statutes, laws, regulations or orders, or an event which results in the creation
of any lien, charge or encumbrance upon any asset of the Company.

availability of equitable remedies. Purchaser represents that he has full power
and authority to enter into this Agreement, and the Investors' Rights Agreement.

            4.2 Purchase for Own Account. The Purchased Shares to be purchased
by Purchaser hereunder will be acquired for investment for Purchaser's own
account, not as a nominee or agent, and not with a view to the public resale or
distribution thereof within the meaning of the 1933 Act, and Purchaser has no
present intention of selling, granting any participation in, or otherwise
distributing the same.

            4.3 Disclosure of Information. Purchaser has received or has had
full access to all the information he considers necessary or appropriate to make
an informed investment decision with respect to the Purchased Shares to be
purchased by Purchaser under this Agreement. Purchaser further has had an
opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of the offering of the Purchased Shares and to obtain
additional information (to the extent the Company possessed such information or
could acquire it without unreasonable effort or expense) necessary to verify any
information furnished




                                       9
<PAGE>   10

to Purchaser or to which Purchaser had access. The foregoing, however, does not
in any way limit or modify the representations and warranties made by the
Company in Section 3.

            4.4 Investment Experience. Purchaser understands that the purchase
of the Purchased Shares involves substantial risk. Purchaser: (a) has experience
as an investor in securities of companies in the development stage and
acknowledges that it is able to fend for himself, can bear the economic risk of
its investment in the Purchased Shares and has such knowledge and experience in
financial or business matters that he is capable of evaluating the merits and
risks of this investment in the Purchased Shares and protecting its own
interests in connection with this investment and/or (b) has a preexisting
personal or business relationship with the Company and certain of its officers,
directors or controlling persons of a nature and duration that enables it to be
aware of the character, business acumen and financial circumstances of such
persons.

            4.5 Accredited Investor Status. Purchaser is an "accredited
investor" within the meaning of Regulation D promulgated under the 1933 Act.

            4.6 Restricted Securities. Purchaser understands that the Purchased
Shares are characterized as "restricted securities" under the 1933 Act inasmuch
as they are being acquired from the Company in a transaction not involving a
public offering and that under the 1933 Act and applicable regulations
thereunder such securities may be resold without registration under the 1933 Act
only in certain limited circumstances. In this connection, Purchaser represents
that he is familiar with Rule 144 of the SEC, as presently in effect, and
understands the resale limitations imposed thereby and by the 1933 Act.
Purchaser understands that the Company is under no obligation to register any of
the securities sold hereunder except as will be provided in the Investors'
Rights Agreement. Purchaser understands that no public market now exists or is
likely to exist for any of the Purchased Shares and that it is uncertain whether
a public market will ever exist for the Conversion Shares.

            4.7 Further Limitations on Disposition. Without in any way limiting
the representations set forth above, Purchaser further agrees not to make any
disposition of all or any portion of the Purchased Shares or the Conversion
Shares unless and until:

                (a) There is then in effect a registration statement under the
1933 Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

                (b) (i) Purchaser shall have notified the Company of the
proposed disposition and shall have furnished the Company with a statement of
the circumstances surrounding the proposed disposition, and (ii) Purchaser shall
have furnished the Company, at the expense of Purchaser or his transferee, with
an opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of such securities under the 1933 Act.

         Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be required: (i) for any
transfer of any Purchased Shares or




                                       10
<PAGE>   11

Conversion Shares in compliance with SEC Rule 144 or Rule 144A except in unusual
circumstances; or (ii) for any transfer of any Purchased Shares or Conversion
Shares by Purchaser to (A) a partner of Purchaser, or (B) the estate of any such
partner, or (iii) for the transfer by gift to any trust for any of the foregoing
or for the benefit of any family member of Purchaser, or (iv) to any entity
controlled by Purchaser or any member of Purchaser; provided that in each of the
foregoing cases the transferee agrees in writing to be subject to the terms of
this Section 4 (other than Section 4.5) to the same extent as if the transferee
were Purchaser hereunder.

            4.8 Legends. It is understood that the certificates evidencing the
Purchased Shares and the Conversion Shares will bear the legends set forth
below:

                (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER THE
SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS
ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS
PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO
REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE
REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD
OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN
FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED
TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE
SECURITIES LAWS.

                (b) Any legend required by the laws of the State of Delaware or
any other state, including a legend substantially in the form of the following:

            THE SHARES EVIDENCED BY THIS CERTIFICATE: (1) ARE CONVERTIBLE INTO
            SHARES OF COMMON STOCK OF THE COMPANY AT THE OPTION OF THE HOLDER AT
            ANY TIME PRIOR TO AUTOMATIC CONVERSION THEREOF; AND (2)
            AUTOMATICALLY CONVERT INTO COMMON STOCK OF THE COMPANY IN THE EVENT
            OF A PUBLIC OFFERING MEETING CERTAIN REQUIREMENTS OR UPON CERTAIN
            CONSENTS OF THE HOLDERS OF THE COMPANY'S PREFERRED STOCK; ALL
            PURSUANT TO AND UPON THE TERMS AND CONDITIONS SPECIFIED IN THE
            COMPANY'S CERTIFICATE OF INCORPORATION. A COPY OF SUCH CERTIFICATE
            OF INCORPORATION MAY BE OBTAINED, WITHOUT CHARGE, AT THE COMPANY'S
            PRINCIPAL OFFICE.

The legend set forth in (a) above shall be removed by the Company from any
certificate evidencing Purchased Shares or Conversion Shares upon delivery to
the Company of an opinion by counsel, reasonably satisfactory to the Company,
that a registration statement under the 1933





                                       11
<PAGE>   12

Act is at that time in effect with respect to the legended security or that such
security can be freely transferred in a public sale without such a registration
statement being in effect and that such transfer will not jeopardize the
exemption or exemptions from registration pursuant to which the Company issued
the Purchased Shares or Conversion Shares. The Company will not require opinions
of counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

         5. MISCELLANEOUS.

        Stock (the "Shares"), at a price of $_________________ per share
        ("Original Issuance Price") and an aggregate purchase price of
        $_____________________. The term "Shares" refers to the purchased
        Shares, all securities or property received in replacement of Shares,
        all securities or property distributed with respect to Shares, in any
        case by way of stock dividends, splits or consolidations, or pursuant

        like.

                  3.1 Right of First Refusal.

                           (a) In the event Purchaser or his transferee desires
                  (or is required) to sell or transfer in any manner any of the
                  Shares, Purchaser shall first offer such Shares for sale to
                  the Company upon the terms and conditions specified herein
                  ("Right of First Refusal") by delivering a notice (the
                  "Notice") to the Company stating

                                    (i)     his bona fide intention to sell or
                         otherwise transfer such Shares,

                                    (ii)    the number of such Shares to be
                         sold to otherwise transferred,

                                    (iii)   the price for which Purchaser
                         proposes to sell such Shares,

                                    (iv)    the name of the proposed buyer or
                         transferee, and

                                    (v)     all additional terms and conditions,
                         if any, of the proposed sale or transfer.

                                    Purchaser shall attach to the Notice a copy
                  of the written offer, if any, reflecting the terms and
                  conditions of the proposed sale or transfer of the Shares to
                  the third party. In the

                                  CONFIDENTIAL                      Page 1 of 10

                  event of a transfer not involving a sale of the Shares for a
                  specific sum of money, or if, in the sole judgement of the
                  Company's Board of Directors, the proposed transfer does not
                  involve a price for the Shares negotiated by Purchaser and its
                  proposed buyer or transferee in a bona fide "arm's length
                  transaction", the price of the Shares shall be determined by
                  the Company's Board of Directors in the manner specified in
                  Section 3.3 below.

                           (b) Within sixty (60) days following receipt by the
                  Company of the Notice ("Acceptance Period"), the Company (or
                  is assignee) may elect to purchase all or a portion of the
                  Shares to which the Notice refers, at the price per Share and
                  on the same terms and conditions (or terms and conditions as
                  reasonably similar as possible) as set forth in the Notice, or
                  at the price per Share determined pursuant to Section 3.3 in
                  the event that the price of the Shares is to be determined by
                  the Company's Board of Directors under Section 3.1 (a).

                           (c) If the Company (or its assignee) elects to
                  purchase such Shares hereunder, it shall notify Purchaser, in
                  writing, of its intention to purchase such Shares hereunder
                  and either (1) set a date for the closing of the transaction
                  at a place specified by the Company not later than thirty (30)
                  days from the date of such notice, at which time the Company
                  (or its assignee) shall tender payment for the Shares, or (2)
                  include payment for the Shares with the Company's notice to
                  Purchaser. At such closing, the certificate(s) representing
                  the Shares so purchased shall be delivered to the Company and
                  canceled (and the Shares transferred to the Company's
                  assignee, if applicable) as of the date of the mailing of the
                  Company's notice and, thereafter, shall be promptly returned
                  by Purchaser to the Company by certified or registered mail.

                           (d) If the Company (or its assignee) does not elect
                  to purchase all of the Shares to which the Notice refers,
                  Purchaser may sell or otherwise transfer the Shares not
                  purchased to the third party named in the Notice at the price
                  and on the terms and conditions specified in the Notice, or at
                  a higher price; provided that such sale or transfer is
                  consummated within sixty (60) days from the earlier of

                                    (i)  the lapse of the Acceptance Period, or

                                    (ii) the date of the Company's notice,
                           whether written or oral, advising Purchaser that the
                           Company does not intend to purchase the Shares
                           hereunder; provided, further, that any such sale or
                           transfer is made in accordance with all of the terms
                           and conditions set forth in this Agreement.

                           In the event the Shares are not disposed of by
                  Purchaser within such sixty (60) day period, such Shares shall
                  once again be subject to the Right of First Refusal.

                  3.2 Involuntary Transfer.

                           (a) In the event of any transfer by operation of law
                  or other involuntary transfer, of all, or a portion, of the
                  Shares, the Company shall have an option to purchase all of
                  the Shares transferred (the "Involuntary Transfer Option") at
                  a price set pursuant to Section 3.3. Upon such a transfer, the
                  person acquiring the Shares shall promptly notify the
                  Secretary of the Company of such transfer.

                           (b) The Company (or its assignee) shall notify
                  Purchaser and the person acquiring the Shares as to whether
                  the Company (or its assignee) wishes to purchase the shares
                  pursuant to the Involuntary Transfer Option within forty-five
                  (45) days following the date on which the Company was notified
                  of the transfer. If the Company (or its assignee) elects to
                  purchase such Shares hereunder it shall set a date for the
                  closing of the transaction at a place specified by the Company
                  not later than thirty (30) days from the date of the Company's
                  notice to Purchaser and the person acquiring the Shares. At
                  such closing, the Company (or its assignee) shall tender
                  payment for the shares in the form of a check, cancellation of
                  Purchaser's indebtedness to the Company, or some combination
                  thereof, and the certificate(s) representing the Shares so
                  purchased shall be canceled.

                  3.3 Determination of Price by Board. With respect to the
         Shares to be transferred pursuant to the Right of First Refusal or the
         Involuntary Transfer Option where the price per Share is to be
         determined pursuant to this Section 3.3, the price per Share shall be
         a price set by the Board of Directors of the Company that is
         determined by the Board to reflect the then current value of such
         Shares. The


                                  CONFIDENTIAL                      Page 2 of 10

         Company shall notify Purchaser, his representative, or the person
         acquiring the Shares under Section 3.2 of the price so determined
         within forty-five (45) days after receipt by the Company of written
         notice of the transfer or proposed transfer of the Shares.

                  3.4 Restriction on Alienation. Any sale, transfer, or
         disposition or purported sale, transfer, or disposition or any of the
         shares by Purchaser shall be null and void unless the terms,
         conditions, and provisions of this Agreement are strictly complied
         with. Purchaser hereby authorizes and directs the Transfer Agent of the
         Company to transfer the Shares as to which the Right of First Refusal
         or Involuntary Transfer Option has been exercised from Purchaser to the
         Company (or its assignee). Purchaser further authorizes the Company to
         refuse, or to cause its Transfer Agent to refuse, to transfer, or
         record any Shares to be transferred in violation of this Agreement.

                  3.5 Assignment by Company. The Company's Right of First
         Refusal, and Involuntary Transfer Option may be assigned, in whole or
         in part, to any shareholder or shareholders of the Company.

                  3.6 Obligations Binding Upon Transferees. All transferees of
         Shares or any interest therein will receive and hold such Shares or
         interests subject to the provisions of this Agreement, including,
         insofar as applicable, the Company's Right of First Refusal, and
         Involuntary Transfer Option under this Section 3. Any sale or transfer
         of the Shares shall be void unless the provisions of this Agreement are
         met.

                  3.7 Termination of Rights. The Right of First Refusal, and the
         Involuntary Transfer Option granted by this Section 3 shall terminate
         (a) on the occurrence of the merger or consolidation of the Company
         into, or the sale of all or substantially all of the Company's assets,
         to another entity, except that these restrictions on transfer shall not
         terminate if immediately after such merger, consolidation, or sale of
         assets, at least fifty-one percent (51%) of the capital stock of such
         other corporation is owned by persons who are holders of Shares of
         capital stock of the Company immediately before such merger,
         consolidation, or sale, or (b) at such time as a public market exists
         for the Company's Common Stock (or any other stock issued to purchasers
         in exchange for the Shares purchased under this Agreement). For the
         purpose of this Agreement, a "public market" shall be deemed to exist
         if the Common Stock is listed on a national securities exchange (as
         that term is used in the Securities Exchange Act of 1934), or the
         Common Stock is traded on the over-the-counter market and prices are
         published daily on business days in a recognized financial journal.

                  3.8 Replacement Certificate. In the event the restrictions
         imposed by this Agreement shall be terminated as provided in this
         Section 3, a new certificate or certificates representing the Shares
         shall be issued, on request, without the legend referred to in Section
         6.1 (b) herein.

                  3.9 Excluded Transfers. The restrictions on transfer of this
         Section 3 shall not apply to an inter-vivos transfer to Purchaser's
         ancestors or descendants or spouse or to a Trustee for their benefit,
         provided that such transferee shall take such Shares subject to all the
         terms of this Agreement, including restrictions on further transfer.

                  3.10 Indebtedness. Notwithstanding any provision to the
         contrary in this Agreement, any payment by the Company for purchase of
         Shares from Purchaser may be made by cancellation of any indebtedness
         to the Company from Purchaser.

                  3.11 Market Standoff Agreement. Purchaser, if requested by the
         Company and an underwriter of Common Stock (or other securities) of
         the Company, agrees not to sell or otherwise transfer or dispose of
         any Common Stock (or other securities) of the Company held by
         Purchaser during the period not to exceed one hundred and eighty (180)
         days as requested by the managing underwriter following the effective
         date of a registration statement of the Company filed under the
         Securities Act (as hereafter defined), provided that all officers and
         directors of the Company are required to enter into similar
         agreements. Such agreement shall be in writing in the form
         satisfactory to the Company and such underwriter. The Company may
         impose stop transfer instructions with respect to the shares (or other
         securities) subject to the foregoing restriction until the end of such
         period.

         4. Escrow; Escrow Instructions. As security for Purchaser's faithful
         performance of the terms and provisions of this Agreement, and to
         insure the availability for delivery of the Shares upon the Company's
         (or its assignee's) exercise of the Right of First Refusal, or
         Involuntary Transfer Option, Purchaser shall, at the Closing Date,
         deliver and deposit with _________________ or such other person
         designated by the Company


                                  CONFIDENTIAL                      Page 3 of 10

         as Escrow Agent in this transaction, the share certificate(s)
         representing the Shares, together with a stock assignment duly
         endorsed in blank (in the form of Exhibit A to this Agreement). The
         Escrow Agent is hereby authorized and directed to hold the documents
         delivered to the Escrow Agent pursuant to the terms of this Agreement,
         including the stock certificate(s), evidencing the Shares and the
         stock assignment in accordance with the following terms of this
         Section 4.

                  4.1 Rights Exercise. In the event the Company (or its
         assignee) shall elect to exercise the Right of First Refusal, or
         Involuntary Transfer Option set forth in Section 3 of this Agreement
         (collectively the "Rights") in whole or in part, the Company (or its
         assignee) shall give to Purchaser and to Escrow Agent a written notice
         specifying a time, place, and/or manner for a closing hereunder.

                  4.2 Closing Instructions. Purchaser and the Company hereby
         irrevocably authorize and direct Escrow Agent to take all such actions
         as may be necessary or proper to close the transaction contemplated by
         such notice in accordance with the terms of such notice. At the
         closing, Escrow Agent is directed to

                           (a) date such stock assignment as shall be necessary
                  for the specific transfer,

                           (b) fill in the number of Shares being transferred,
                  and

                           (c) deliver the same, together with the
                  certificate(s) evidencing the Shares to be transferred, to the
                  Company (or its assignee) as provided in this Agreement
                  against the simultaneous delivery to Escrow Agent of the
                  purchase price for the number of Shares being purchased
                  pursuant to this Agreement.

                  4.3 Additional Share Deposit. Purchaser irrevocably authorizes
         the Company to deposit with Escrow Agent any securities (including
         additional shares of the Company's Common Stock) or other property
         (including cash) which Purchaser would be entitled to receive on
         account of any Shares held by Escrow Agent hereunder. To facilitate the
         performance of this Agreement, Purchaser irrevocably constitutes and
         appoints Escrow Agent as his attorney-in-fact and agent for the term of
         the escrow to execute with respect to such Shares all stock
         certificates, stock assignments, or other instruments, which shall be
         necessary or appropriate to make such securities negotiable and to
         complete any transaction contemplated under this Agreement, including
         but not limited to any filings to comply with state or federal
         securities laws.

                  4.4 Share Release. Upon written request from the Company and
         Purchaser, Escrow Agent is authorized to release from escrow the number
         of Shares indicted in that written request pursuant to this Agreement.

                  4.5 Escrow Termination. The escrow shall terminate upon the
         termination of the Company's Rights under Section 3 of this Agreement.
         Upon termination of this escrow, Escrow Agent shall deliver to
         Purchaser all documents, securities, or other property belonging to
         Purchaser that are still in Escrow Agent's possession, and Escrow Agent
         shall be discharged of all further obligations under Section 4.

                  4.6 Escrow Amendment. Escrow Agent's duties hereunder may be
         altered, amended, modified, or revoked only by a writing signed by all
         of the parties to this Agreement and approved by Escrow Agent.

                  4.7 Escrow Agent Liability. Escrow Agent shall not be
         personally liable for any act Escrow Agent may do or omit to do
         hereunder as Escrow Agent or attorney-in-fact for Purchaser while
         acting in good faith and in the exercise of Escrow Agent's own good
         judgement and any act done or omitted by Escrow Agent pursuant to the
         advice of Escrow Agent's own attorneys shall be conclusive evidence of
         such good faith. Escrow Agent shall not be liable in any respect on
         account of the identities, authorities, or rights of the parties
         executing or delivering or purporting to execute or deliver this
         Agreement or any documents or papers deposited or called for hereunder.
         Escrow Agent shall not be liable for the termination of any rights
         under any applicable statute of limitations with respect to the
         provisions of this Section 4 or any documents deposited with Escrow
         Agent.

         to disregard any and all warnings given by any of the parties hereto or

         obey orders, judgements, or decrees of any court. In case Escrow Agent

         judgement, or decree of any court, Escrow Agent shall not be liable to
         any of the parties hereto or to any other person, firm, or corporation
         by reason of such compliance, notwithstanding that any such order,
         judgement, or decree shall be subsequently reversed, modified,
         annulled, set aside, vacated, or found to have been entered without
         jurisdiction.

                  4.9 Execution Effect. By signing this Agreement, the Escrow
         Agent becomes a party hereto only for the purpose of Section 4. and
         for no other provisions of this Agreement.

                  4.10 Escrow Agent Successors. If, prior to the termination of
         this Escrow, ____________ shall die or shall cease to be Escrow Agent
         of the Company, any other officer of the Company may, from time to
         time, at the request of the Company's Board of Directors, discharge any
         of the duties and perform any of the acts to be performed by
         __________________ as Escrow Agent.

         5. Investment Representations. In connection with the
         acquisition of the Shares, Purchaser represents to the Company the
         following:

                  5.1 Investment. Purchaser is acquiring the Shares to be issued
         to Purchaser for investment for Purchaser's own account and not with
         the view to, or for resale in connection with, any distribution,
         assignment, or resale within the meaning of the Securities Act of 1933
         (the "Securities Act"), or the Delaware Corporate Securities Law, as
         amended ("Delaware Securities Law") to others and no other person has a
         direct or indirect beneficial interest, in whole or in part, in such
         Shares. Purchaser understands that the Shares to be issued to Purchaser
         have not been and will not be registered under the Securities Act or
         qualified under the Delaware Securities Law, or under the laws of any
         other state of the United States in reliance upon specific exemptions
         therefrom which depend upon, among other things, the bona fide nature
         of the investment intent as expressed herein, and in any other
         representations, warranties, or information provided by Purchaser to
         the Company under this Agreement.

                  5.2 Restrictions on Transfer. Purchaser acknowledges that the
         Shares to be issued to Purchaser must be held indefinitely unless
         subsequently registered and qualified under the Securities Act, or
         unless an exemption from registration and qualification is otherwise
         available. Purchaser further understands that the Company is under no
         obligation to register or qualify the Shares.

                  5.3 Rule 144. Purchaser is aware of the provisions of Rule
         144, promulgated under the Securities Act, which permits limited public
         resale of "restricted securities" acquired, directly or indirectly,
         from the issuer thereof (or from an affiliate of such issuer), in a
         non-public offering subject to the satisfaction of certain conditions.

                  5.4 Exemption from Registration. Purchaser further
         acknowledges that, in the event all of the applicable requirements of
         Rule 144 are not satisfied, registration under the Securities Act,
         compliance with Regulation A, or some other registration exemption will
         be required.

                  5.5 Relationship to Company; Experience. Purchaser either has
         a preexisting business or personal relationship with the Company or any
         of its officers, directors, or controlling persons or, by reason of
         Purchaser's business or financial experience, has the capacity to
         protect Purchaser's own interests in connection with Purchaser's
         acquisition of the Shares to be issued to Purchaser hereunder.
         Purchaser has such knowledge and experience in financial, tax, and
         business matters to enable Purchaser to utilize the information made
         available to Purchaser in connection with the acquisition of the Shares
         to evaluate the merits and risks of the prospective investment and to
         make an informed investment decision with respect thereto.

                  5.6 Purchaser's Liquidity. In reaching the decision to invest
         in the Shares, Purchaser has carefully evaluated Purchaser's financial
         resources and investment position and the risks associated with this
         investment, and Purchaser acknowledges that Purchaser is able to bear
         the economic risks of the investment. Purchaser

                           (a) has adequate means of providing for
                  Purchaser's current needs and possible personal contingencies,

                           (b) has no need for liquidity in Purchaser's
                  investment,

                           (c) is able to bear the substantial economic
                  risks of an investment in the Shares for an indefinite period,
                  and

                                  CONFIDENTIAL                      Page 5 of 10

<PAGE>   6



                           (d) at the present time, can afford a complete loss
                  of such investment. Purchaser's commitment to investments
                  which are not readily marketable is not disproportionate to
                  Purchaser's net worth, and Purchasers investment in the Shares
                  will not cause Purchaser's overall commitment to become
                  excessive.

                  5.7 Offer and Sale. Purchaser understands that the offer and
         sale of the Shares have not been registered under the Securities Act in
         reliance upon exemption therefrom. Purchaser was not offered or sold
         the Shares, directly or indirectly, by means of any form of general
         solicitation or general advertisement, including the following:

                           (a) any advertisement, article, notice, or other
                  communication published in any newspaper, magazine, or
                  similar medium, or broadcast over television or radio; or

                           (b) any seminar or meeting whose attendees had been
                  invited by general solicitation or general advertising.

                  5.8 Access to Data. Purchaser is aware of the Company's
         business affairs and financial condition, and has acquired sufficient
         information about the Company to reach an informed and knowledgeable
         decision to acquire the Shares. Purchaser acknowledges that during the
         course of this transaction and before deciding to acquire the Shares,
         Purchaser has been provided with financial and other written
         information about the Company. Purchaser has been given the opportunity
         by the Company to obtain any information and ask questions concerning
         the Company, the Shares, and Purchaser's investment that Purchaser felt
         necessary; and to the extent Purchaser availed himself of that
         opportunity, Purchaser has received satisfactory information and
         answers.

                  5.9 Risks. Purchaser acknowledges and understands that

                           (a) any investment in the Company constitutes a high
                  risk,

                           (b) the Shares are highly speculative, and

                           (c) there can be no assurance as to what return, if
                  any, there may be.

                            Purchaser is aware that the Company may issue
         additional securities in the future which could result in the dilution
         of Purchaser's ownership interest in the Company.

                  5.10 Valid Agreement. This Agreement, when executed and
         delivered by Purchaser, shall constitute a valid and legally binding
         obligation of Purchaser which is enforceable in accordance with its
         terms.

                  5.11 Residence. The address set forth on the signature page of
         this Agreement is Purchaser's current address and accurately sets forth
         Purchaser's place of residence.

         6. Securities Compliance.

                  6.1 Legends. The certificate or certificates representing the
         Shares shall bear legends in substantially the following form (in
         addition to any other legend imposed by applicable blue sky laws or the
         Articles or Bylaws of the Company):

                  AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO, OR AN
                  OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS
                  NOT REQUIRED UNDER THE SECURITIES ACT OF 1993.

                                    (b) THE SHARES REPRESENTED BY THIS

                              Due February 5, 1999

Chaparral Technologies, Inc., a Delaware corporation (the "Corporation"), for
value received, promises to pay to William R. Childs or registered assigns, the
sum of $250,000 on February 5, 1999, upon presentation and surrender of this
Debenture at the office of the Corporation in Longmont, Colorado, and to pay
interest at the rate of 8 interest per annum computed from August 5, 1998 (the
"issue date"), until payment of the principal amount of this Debenture has been
made. Payment of principal and interest shall be made at the offices of the
Corporation, in lawful money of the United States of America, and shall be
mailed to the registered owner hereof at the address appearing on the books of
the Corporation.

         1.       Conversion. The holder of this Debenture may, at any time
                  prior to the maturity hereof, convert the principal amount of
                  this Debenture into common stock of the Corporation at the
                  conversion ratio of $0.50 of debenture principal for one share
                  of common stock, or at the adjusted conversion price in effect
                  at the time of the conversion; provided that if the
                  Corporation has called this Debenture for redemption, the
                  right to convert shall terminate at the close of business on
                  the second business day prior to the day fixed as the date for
                  the redemption.

                  To convert this Debenture, the holder must surrender the same
                  at the office of the Corporation, accompanied by a written
                  notice of conversion and by a written notice of conversion and
                  by a written instrument of transfer in a form satisfactory to
                  the Corporation, properly completed and executed by the
                  registered holder hereof or a duly authorized attorney.

         2.       Fractional shares. In lieu of issuing any fraction of a share
                  or scrip upon the conversion of this Debenture, the
                  Corporation shall pay to the holder hereof for any fraction of
                  a share otherwise issuable upon the conversion, cash equal to
                  the same fraction of the then current per share market price
                  of the common stock.

         3.       Adjustments to conversion. If the Corporation at any time
                  subdivides or combines in a larger or smaller number of shares
                  its outstanding shares of common stock, then the number of
                  shares of common stock issuable upon the conversion of this
                  Debenture shall be proportionally increased in the case of a
                  subdivision and decreased in the case of a combination,
                  effective in either case at the close of business on the date
                  that the subdivision or combination becomes effective.

                           Void after August 18, 2004

         This certifies that, subject to the terms and conditions set forth
herein, for value received, Gary L. Allison, (the "Holder") or its registered

nonassessable shares of Common Stock, $0.001 par value, of the Company (as
adjusted pursuant to Section 7 hereof, the "Shares") at the purchase price per
share specified in Section 2 below.

         1. Definitions. As used in this Warrant, the following terms, unless
the context otherwise requires, have the following meanings:

                  (a) "Common Stock", when used with reference to stock of the
Company, means all shares, now or hereafter authorized, of the class of Common
Stock, $0.001 par value, of the Company currently authorized and shares of any
other class into which those shares may hereafter be changed.

                  (b) "Company" means Chaparral Network Storage, Inc. a Delaware
corporation and any corporation which shall succeed to or assume the obligations
of the Company under this Warrant.

                  (c) "1933 Act" means the Securities Act of 1933, as amended.

                  (d) "1934 Act" means the Securities Exchange Act of 1934, as
amended.

                  (e) "Convertible equity securities" or "equity securities"
shall mean any of the Company's securities.

                  (f) "Holder" means Sentinel Consulting, LLC, a Delaware

                  (g) The terms "register", "registered" and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with


                                       1
<PAGE>   2


the 1933 Act, and the declaration or ordering of the effectiveness of such
registration statement or document by the SEC.

                  (h) The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

         2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.125 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

         3. Exercise Period. This Warrant shall be exercisable by the Holder for
a term beginning on August 19, 1999, (the "Commencement Date") and ending on
August 18, 2004, (the "Expiration Date").

         4. Method of Exercise.


                  (a) The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                           (i)  the surrender of the Warrant, together with a
duly executed copy of the form of subscription attached hereto as Appendix I, to
the Secretary of the Company at its principal offices; and

                           (ii) the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

                  (b) In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                           A

Where X= the number of Shares to be issued to the Holder.

                                       2
<PAGE>   3


         Y= the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A= the fair market value of one Share (at the date of such exercise).

         B= the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common Stock
         quoted in the NASDAQ National Market System or the Over-the-Counter
         market or the closing price quoted on any exchange on which the Common
         Stock is listed, whichever is applicable, as published in the Western
         Edition of The Wall Street Journal for the five (5) trading days prior
         to the date of determination of the fair market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

                  (c) Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

                  (d) In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of


                                       3
<PAGE>   4


this Warrant for the full number of Shares specified herein and the conversion
of the Shares into Common Stock. The Company further covenants that such Shares,
when issued pursuant to the exercise of this Warrant, will, upon issuance, be
duly and validly issued, fully paid and non-assessable and free from all taxes,
liens and charges with respect to the issuance thereof.

         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the purchase
price therefor shall be subject to adjustment from time to time as follows:

                  (a) Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

                  (b) Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

                  (c) Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.


                                       4
<PAGE>   5


                  (d) Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

                  (e) No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

         8. Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

         9. Exercise, Transfer and Exchange Restrictions.

                  (a) This Warrant, and any rights hereunder, may not be
assigned or transferred, except as provided herein and in accordance with and
subject to the provisions of (i) applicable state securities laws, and (ii) the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (such Act and such rules and regulations being hereinafter
collectively referred to as the "Act"). Any purported transfer or assignment
made other than in accordance with this Section 9 shall be null and void and of
no force and effect.

                  (b) This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer


                                       5
<PAGE>   6


or assignment, the assignor or transferor shall reimburse the Company for its
reasonable expenses, including transfer taxes and attorneys' fees, incurred in
connection with the transfer or assignment.

                  (c) Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

         10. Registration Rights.

                  (a) Requested Registration.

                           (i) Request for Registration. In case the Company
shall receive from the Holder a written request that the Company file a
registration statement under the 1933 Act with respect to shares of Registrable
Securities having an expected aggregate offering price of at least One Million
Dollars ($1,000,000), the Company will, subject to the limitations of Section
9(a)(ii), use its best efforts to effect such registration under the 1933 Act
(including, without limitation, appropriate qualification under applicable blue
sky or other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                                    (A) In any particular jurisdiction in which
the Company would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the Company
is already subject to service in such jurisdiction and except as may be required
by the 1933 Act;

                                    (B) Prior to the six (6) months after the
closing date of the Company's first registered public offering of its stock
(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);

                                    (C) During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good


                                       6
<PAGE>   7


faith and using all reasonable efforts to cause such initial registration
statement to become effective;

                                    (D) After the Company has effected one (1)
such registration pursuant to a Holder's demand under this Section 10(a)(i),
which registration has been declared effective; or

                                    (E) If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                  (ii) Underwriting. In the event that a registration pursuant
to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

         (b) Piggy-back Registration Rights.

                  (i) Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii),


                                       7
<PAGE>   8


use its best efforts to cause to be registered under the 1933 Act all of the
Registrable Securities that the Holder has requested to be registered. The
Company shall be required to effect not more than three (3) such registrations
of Registrable Securities pursuant to the request of the Holder under this
Section 10(b).

                  (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

         (c) Obligations of the Company. Whenever required under this Section 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                  (i) 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
Holder, keep such registration statement effective for up to one hundred twenty
(120) days.

                  (ii) 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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                  (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                  (iv) Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such


                                       8
<PAGE>   9


expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                  (v) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement with terms
generally satisfactory to the managing underwriter of such offering. The Holder
shall also enter into and perform its obligations under such an agreement.

                  (vi) Notify the Holder, at any time when a prospectus relating
thereto is required to be delivered under the 1933 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 light of the circumstances then
existing. In such instance, Company shall use its best efforts to cure any such
statement or omission so as to render such statement or omission not misleading.

         (d) Furnish Information. In connection with any action pursuant to this
Section 10, the 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 their Registrable Securities. In that connection, the Holder shall be
required to represent to the Company that all such information which is given is
both complete and accurate in all material respects when made.

         (e) Definition of Expenses.

                  (i) "Registration Expenses" shall mean all expenses incurred
by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                  (ii) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of the Registrable Securities in
the registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

         (f) Expenses of Registration. The Company shall bear all Registration
Expenses incurred in connection with (i) any registration, qualification or
compliance pursuant to Section 10(a), and (ii) no more than three (3)
registrations pursuant to Section 10(b). All Selling Expenses shall be borne by
the Holder.

         (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:

                  (i) To the extent permitted by law, the Company will indemnify
and hold harmless the Holder, the officers, directors and partners of the
Holder, any underwriter (as defined in the 1933 Act) for the Holder and each
person, if any, who controls the Holder or underwriter within the meaning of the
1933 Act or the 1934 Act, against any losses, claims, damages, or liabilities
(joint or several) to which they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the 1933 Act, the 1934 Act or any state securities
law; and the Company will reimburse the Holder, officer, director or partner,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
Company's indemnity contained in this Section 10(g) 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 Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable 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 in writing and expressly stated
for use in connection with such registration by the Holder, or the Holder's
officers, directors or partners, underwriter, or controlling person. The Company
shall not be required to indemnify any person against any liability arising (i)
from any untrue or misleading statement or omission contained in any preliminary
prospectus if such deficiency is corrected in the final prospectus or (ii) out
of the failure of any person to deliver a prospectus as required by the 1993
Act. The indemnity provided for in this Section 10(g) shall remain in full force
and effect regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                  (ii) To the extent permitted by law, the Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other security holder in such registration statement or any of its partners,
directors or officers or any person who controls such security holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 Act, the 1934 Act or
other federal or state law, insofar as such


                                       10
<PAGE>   11


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 the Holder expressly stated in a writing for
use in connection with such registration; and the Holder will reimburse any
legal or other expenses, as incurred, where same are reasonably incurred by any
person intended to be indemnified pursuant to this Section 10(g), in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
Section 10(g) 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.
Notwithstanding the foregoing, the liability of each Holder under this Section
10(g) shall be limited to an amount equal to the public offering price of the
shares sold by the Holder.

                  (iii) Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                  (iv) In order to provide for just and equitable contribution
to joint liability under the 1933 Act in any case in which either (i) any
indemnified party makes a claim under this Section 10(g) or any controlling
person of such indemnified party makes such a claim but is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) 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


                                       11
<PAGE>   12


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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the Investor
Rights Agreement and (iii) the Holder shall not make a demand registration which
could result in such registration statement being declared effective prior six
months after the effective date of the Company's initial public offering of
securities pursuant to a registration filed under the 1933 Act or within one
hundred twenty (120) days of the effective date of any demand registration
pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.

                  (i) The Company shall have no obligations pursuant to Section
10 with respect to any request or requests made by the Holder after the date
which is five (5) years following the date of the consummation of the first sale
of securities pursuant to a registration statement filed by the Company under
the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                  (ii) Notwithstanding any contrary provision of this Section
10(i), the Company shall not be required to effect any registrations under the
1933 Act or under any state securities laws on behalf of the Holder if, in the
opinion of counsel to the Company, the offering or transfer by such Holder in
the manner proposed (including, without limitation, the number of shares
proposed to be offered or transferred, the time of sale, and the method of
offering or transfer) is exempt from the registration requirements of the 1933
Act and the securities laws of applicable states and the Company consents to
such transfer, if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock  of the Company (other than those Common
Stock


                                       12
<PAGE>   13


shares included in the registration) without the prior written consent of the
Company or such underwriters, as the case may be, for such period of time (not
to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares of securities of every
other person subject to the foregoing restriction) until the end of such period.

         12. Miscellaneous Provisions.

                  (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

                  (b) Replacement. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense will execute and deliver, in lieu of this
Warrant a new Warrant of like tenor.

                  (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

                  (d) Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

                  (e) Notices. All notices from the Company to the holder of
this Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized


                                       13
<PAGE>   14


reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to have been given
as provided above, whether by mail or by courier, as applicable, if transmitted
by telecopier, whichever shall first occur.


         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its duly authorized officer.

                         CHAPARRAL NETWORK STORAGE, INC.
                        WARRANT TO PURCHASE COMMON STOCK
                       OF CHAPARRAL NETWORK STORAGE, INC.
                 Void after 3:00 p.m. M.S.T., December 13, 2000


         1. Basic Terms. This certifies that, for value received, Bill Childs.
(hereinafter the "Registered Owner") is entitled, subject to the terms and
conditions of this Warrant, until the expiration date of 3:00 p.m. M.S.T.,
December 13, 2000, to purchase up to and including One Hundred Five thousand
(105,000) shares of the Common Stock, par value $0.001 ("the Common Stock") (as
may be adjusted herein), of Chaparral Network Storage, Inc. (the "Corporation")
from the Corporation at the purchase price of one dollar ($1.00) a share, upon
delivery of this Warrant to the Corporation along with the Subscription Form
duly executed and payment of the aggregate purchase price (in cash or by
certified or bank cashier's check payable to the order of the Corporation) for
each share purchased, and as more fully set forth herein.

            Registered Owner of Warrant:  Bill Childs

            Purchase Price:               One dollar ($1.00) per share of common
                                          stock

            Expiration Date of Warrant:   3:00 p.m. M.S.T., December 13, 2000.

         2. Corporation's Covenants as to Common Stock. Shares deliverable on
the exercise of this Warrant shall, at delivery, be fully paid and
non-assessable, free from taxes, liens, and charges with respect to their
purchase. The Corporation shall at all times reserve and hold available
sufficient shares of Common Stock to satisfy all conversion and purchase rights
of outstanding convertible securities, options and warrants.

         3. Automatic Termination. In the event of (i) the closing of the
Corporation's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Corporation's securities is sold to
the public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Corporation in a merger, business
combination, or other form of business transaction, then the Corporation shall
give the Registered Owner of this Warrant at least fifteen (15) days written
notice of the proposed effective date and terms of such offering, transaction or
agreements, and if the Warrant has not


<PAGE>   16


been exercised at least before the effective date of such offering, transaction
or agreements, then this Warrant and the rights hereunder shall be automatically
terminated.

         4. Method of Exercise; Fractional Shares. The Registered Owner may
exercise from time to time, in whole or in part on or before the Expiration Date
above noted, the purchase rights evidenced hereby, provided, however, that
purchase rights are not exercisable with respect to a fraction of a share of
Common Stock. Such exercise shall be effected by:

              (i)   The surrender of the Warrant, together with a duly executed
copy of the form of subscription attached hereto as Appendix I, to the Secretary
of the Corporation at its principal offices; and

              (ii)  The payment to the Corporation, in cash or by check payable
to the order of the Corporation, of an amount equal to the aggregate purchase
price for the number of shares designated for purchase in the completed
subscription form; and

              (iii) Upon the request of the Corporation, the Registered Owner
shall also deliver to the Corporation an instrument, in form and substance
reasonably satisfactory to counsel for the Corporation, executed by the
Registered Owner certifying that the shares are being acquired for investment
purposes only and not with a view to their resale or distribution; and

In the event of a partial exercise of this Warrant, a new Warrant shall be
issued to the Registered Owner representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice. The Corporation shall not be
required to issue any fractional shares upon the exercise of the Registered
Owner's purchaser rights under this Warrant. In lieu of any fractional shares,
the Corporation shall pay cash equal to such fraction multiplied by the per
share market price of the Common Stock as of the date of exercise.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of shares so
purchased shall be issued in the name of the Registered Owner as soon as
practicable following receipt of the completed subscription form and payment for
the shares being purchase and in any event within ten (10) days thereafter.

         6. Adjustment of Price and Shares Available for Purchase. The number of
shares available for purchase hereunder and the purchase price per share are
subject to adjustment from time to time as specified in this Warrant.

         7. Limited Rights of Registered Owner. This Warrant does not entitle
the Registered Owner to any voting rights or other rights as a Stockholder of
the Corporation, or to any other rights whatsoever except the rights herein
expressed. No dividends are payable or will accrue on this Warrant or the shares
available for purchase hereunder until, and except to the extent that, this
Warrant is exercised.

         8. Exchange for Other Denominations. This Warrant is exchangeable, on
its surrender by the Registered Owner to the Corporation, for new Warrants of
like tenor and date


                                       2
<PAGE>   17


representing in the aggregate the right to purchase the number of shares
available for purchase hereunder in denominations designated by the Registered
Owner at the time of surrender.

         9. Transfer.

            (a) This Warrant, and any rights hereunder, may not be assigned or
transferred, except as provided herein and in accordance with and subject to the
provisions of (i) applicable state securities laws, and (ii) the Securities Act
of 1933, as amended, and the rules and regulations promulgated thereunder (such
Act and such rules and regulations being hereinafter collectively referred to as
the "Act"). Any purported transfer or assignment made other than in accordance
with this Section 9 shall be null and void and of no force and effect.

            (b) This Warrant, and any rights hereunder, may be transferred or
assigned only with the prior written consent of the Corporation, which shall be
granted only upon receipt by the Corporation of an opinion of counsel
satisfactory to the Corporation that (i) the transferee is a person to whom this
Warrant may be legally transferred without registration under the Act, and (ii)
such transfer will not violate any applicable law or governmental rule or
regulation, including, without limitation, any applicable federal or state
securities law. Prior to the transfer or assignment, the assignor or transferor
shall reimburse the Corporation for its reasonable expenses, including transfer
taxes and attorneys' fees, incurred in connection with the transfer or
assignment.

            (c) Any assignment permitted hereunder shall be made by surrender of
this Warrant to the Corporation at its principal office with an assignment in a
form satisfactory to the Corporation duly executed and funds sufficient to pay
any transfer tax. In such event, the Corporation shall, without charge, execute
and deliver a new Warrant in the name of the assignee named in such instrument
of assignment and this Warrant shall be promptly canceled.

         10. Recognition of Registered Owner. Prior to due presentment for
registration of transfer of this Warrant, the Corporation may treat the
Registered Owner as the person exclusively entitled to receive notices and
otherwise to exercise rights hereunder.

         11. Effect of Stock Split, Etc. If the Corporation, by stock dividend,
split, reverse split, reclassification of shares, or otherwise, changes as a
whole the outstanding Common Stock into a different number or class of shares,
then:

             (a) the number and class of shares so changed shall, for the
purposes of this Warrant, replace the shares outstanding immediately prior to
the change; and

             (b) the Warrant purchase price in effect, and the number of shares
available for purchase under this Warrant, immediately prior to the date upon
which the change becomes effective, shall be proportionately adjusted (the price
to the nearest cent). Irrespective of any adjustment or change in the Warrant
purchase price or the number of shares purchasable under this or any other
Warrant of like tenor, the Warrants theretofore and thereafter issued may
continue to express the Warrant purchase price per share and the number of
shares available for purchase as the Warrant purchase price per share and the
number of shares available for purchase were expressed in the Warrants when
initially issued.


                                       3
<PAGE>   18


         12. Notice of Adjustment. On the happening of an event requiring an
adjustment of the Warrant purchase price or the shares available for purchase
hereunder, the Corporation shall forthwith give written notice to the registered
owner stating the adjusted Warrant purchase price and the adjusted number and
kind of securities or other property available for purchase hereunder resulting
from the event and setting forth in reasonable detail the method of calculation
and the facts upon which the calculation is based. The Board of Directors of the
Corporation, acting in good faith, shall determine the calculation.

         13. Notice and Effect of Dissolution, Etc. In case a voluntary or
involuntary dissolution, liquidation, or winding up of the Corporation is at any
time proposed, the Corporation shall give at least a 30-day written notice to
the registered owner. Such notice shall contain: (a) the date on which the
transaction is to take place; (b) the record date (which shall be at least 30
days after the giving of the notice) as of which holders of Common Shares will
be entitled to receive distributions as a result of the transaction; (c) a brief
description of the transaction; (d) a brief description of the distributions to
be made to holders of Common Stock as a result of the transaction; and (e) an
estimate of the fair value of the distributions. On the date of the transaction,
if it actually occurs, this Warrant and all rights hereunder shall terminate.

         14. Method of Giving Notice; Extent Required. Notices shall be given by
first class mail, postage prepaid, addressed to the Registered Owner at the
address of the owner appearing in the records of the Corporation. No notice to
warrant holders is required except as specified herein.

         15. "Market Stand-off" Agreement. Subject to the terms and conditions
of paragraph 3 hereof, the Registered Owner agrees, so long as the Registered
Owner holds at least one percent (1%) of the Corporation's outstanding voting
equity securities, in connection with the Corporation's initial underwritten
public offering of the Corporation's securities that, upon request of the
Corporation or the underwriters managing any underwritten offering of the
company's securities, not to sell, make any short sale of, loan, grant any
option for the purchase of, or otherwise dispose of any Common Stock of the
Corporation without the prior written consent of the Corporation or such
underwriters, as the case may be, for such period of time (not to exceed one
hundred eighty (180) days) from the closing date of such registration as may be
requested by the underwriters; provided, however, that such covenants shall
apply on if (i) all of the officers and directors of the Corporation who own
stock of the Corporation and (ii) each shareholder owning more than two percent
(2%) of the Corporation's shares also agree to such restrictions on any shares
not being registered in such offering. In order to enforce the foregoing
covenant, the Corporation may impose stop-transfer instructions with respect to
the shares of the Registered Owner (and the shares of securities of every other
person subject to the foregoing restriction) until the end of such period.

         16. Governing Law. This Warrant shall be governed by and construed and
enforced in accordance with the laws of the State of Colorado applicable to
contracts entered into and wholly to be performed in Colorado by Colorado
residents.

                        WARRANT TO PURCHASE COMMON STOCK
                       OF CHAPARRAL NETWORK STORAGE, INC.
                           Void after August 12, 2004

         This certifies that, subject to the terms and conditions set forth
herein, for value received, William R. Childs, (the "Holder") or its registered
assigns is entitled to purchase from Chaparral Network Storage, Inc., a Delaware
corporation (the "Company") up to twenty five thousand (25,000) fully paid and
nonassessable shares of Common Stock, $0.001 par value, of the Company (as
adjusted pursuant to Section 7 hereof, the "Shares") at the purchase price per
share specified in Section 2 below.

         1. Definitions. As used in this Warrant, the following terms, unless
the context otherwise requires, have the following meanings:

                  (a) "Common Stock", when used with reference to stock of the
Company, means all shares, now or hereafter authorized, of the class of Common
Stock, $0.001 par value, of the Company currently authorized and shares of any
other class into which those shares may hereafter be changed.

                  (b) "Company" means Chaparral Network Storage, Inc. a Delaware
corporation and any corporation which shall succeed to or assume the obligations
of the Company under this Warrant.

                  (c) "1933 Act" means the Securities Act of 1933, as amended.

                  (d) "1934 Act" means the Securities Exchange Act of 1934, as
amended.

                  (e) "Convertible equity securities" or "equity securities"
shall mean any of the Company's securities.

                  (f) "Holder" means Sentinel Consulting, LLC, a Delaware

                  (g) The terms "register", "registered" and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with


                                       1
<PAGE>   21


the 1933 Act, and the declaration or ordering of the effectiveness of such
registration statement or document by the SEC.

                  (h) The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

         2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.50 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

         3. Exercise Period. This Warrant shall be exercisable by the Holder for
a term beginning on August 13, 1999, (the "Commencement Date") and ending on
August 12, 2004, (the "Expiration Date").

         4. Method of Exercise.

                  (a) The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                           (i)   the surrender of the Warrant, together  with a
duly executed copy of the form of subscription attached hereto as Appendix I, to
the Secretary of the Company at its principal offices; and

                           (ii)  the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

                  (b) In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                           A

Where X= the number of Shares to be issued to the Holder.


                                       2
<PAGE>   22




         Y= the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A= the fair market value of one Share (at the date of such exercise).

         B= the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common Stock
         quoted in the NASDAQ National Market System or the Over-the-Counter
         market or the closing price quoted on any exchange on which the Common
         Stock is listed, whichever is applicable, as published in the Western
         Edition of The Wall Street Journal for the five (5) trading days prior
         to the date of determination of the fair market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

                  (c) Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

                  (c) In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into


                                       3
<PAGE>   23


Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the purchase
price therefor shall be subject to adjustment from time to time as follows:

                  (a) Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

                  (b) Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

                  (c) Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.


                                       4
<PAGE>   24


                  (d) Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

                  (e) No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

         8. Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

         9. Exercise, Transfer and Exchange Restrictions.

                  (a) This Warrant, and any rights hereunder, may not be
assigned or transferred, except as provided herein and in accordance with and
subject to the provisions of (i) applicable state securities laws, and (ii) the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (such Act and such rules and regulations being hereinafter
collectively referred to as the "Act"). Any purported transfer or assignment
made other than in accordance with this Section 9 shall be null and void and of
no force and effect.

                  (b) This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable


                                       5
<PAGE>   25


expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

                  (c) Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

         10. Registration Rights.

                  (a) Requested Registration.

                           (i) Request for Registration. In case the Company
shall receive from the Holder a written request that the Company file a
registration statement under the 1933 Act with respect to shares of Registrable
Securities having an expected aggregate offering price of at least One Million
Dollars ($1,000,000), the Company will, subject to the limitations of Section
9(a)(ii), use its best efforts to effect such registration under the 1933 Act
(including, without limitation, appropriate qualification under applicable blue
sky or other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                                    (A) In any particular jurisdiction in which
the Company would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the Company
is already subject to service in such jurisdiction and except as may be required
by the 1933 Act;

                                    (B) Prior to the six (6) months after the
closing date of the Company's first registered public offering of its stock
(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);

                                    (C) During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good faith and using all reasonable efforts to cause such initial
registration statement to become effective;


                                       6
<PAGE>   26


                                    (D) After the Company has effected one (1)
such registration pursuant to a Holder's demand under this Section 10(a)(i),
which registration has been declared effective; or

                                    (E) If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                  (ii) Underwriting. In the event that a registration pursuant
to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

         (b) Piggy-back Registration Rights.

                  (i) Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).


                                       7
<PAGE>   27


                  (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

         (c) Obligations of the Company. Whenever required under this Section 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                  (i)   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
Holder, keep such registration statement effective for up to one hundred twenty
(120) days.

                  (ii)  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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                  (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                  (iv)  Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                  (v)   In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement with terms
generally satisfactory to the managing


                                       8
<PAGE>   28


underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                  (vi) Notify the Holder, at any time when a prospectus relating
thereto is required to be delivered under the 1933 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 light of the circumstances then
existing. In such instance, Company shall use its best efforts to cure any such
statement or omission so as to render such statement or omission not misleading.

         (d) Furnish Information. In connection with any action pursuant to this
Section 10, the 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 their Registrable Securities. In that connection, the Holder shall be
required to represent to the Company that all such information which is given is
both complete and accurate in all material respects when made.

         (e) Definition of Expenses.

                  (i) "Registration Expenses" shall mean all expenses incurred
by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                  (ii) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of the Registrable Securities in
the registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

         (f) Expenses of Registration. The Company shall bear all Registration
Expenses incurred in connection with (i) any registration, qualification or
compliance pursuant to Section 10(a), and (ii) no more than three (3)
registrations pursuant to Section 10(b). All Selling Expenses shall be borne by
the Holder.

         (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:

                  (i) To the extent permitted by law, the Company will indemnify
and hold harmless the Holder, the officers, directors and partners of the
Holder, any underwriter (as


                                       9
<PAGE>   29


defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                  (ii) To the extent permitted by law, the Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other security holder in such registration statement or any of its partners,
directors or officers or any person who controls such security holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity


                                       10
<PAGE>   30


agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                  (iii) Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                  (iv) In order to provide for just and equitable contribution
to joint liability under the 1933 Act in any case in which either (i) any
indemnified party makes a claim under this Section 10(g) or any controlling
person of such indemnified party makes such a claim but is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent


                                       11
<PAGE>   31


misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the Investor
Rights Agreement and (iii) the Holder shall not make a demand registration which
could result in such registration statement being declared effective prior six
months after the effective date of the Company's initial public offering of
securities pursuant to a registration filed under the 1933 Act or within one
hundred twenty (120) days of the effective date of any demand registration
pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.

                  (i) The Company shall have no obligations pursuant to Section
10 with respect to any request or requests made by the Holder after the date
which is five (5) years following the date of the consummation of the first sale
of securities pursuant to a registration statement filed by the Company under
the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                  (ii) Notwithstanding any contrary provision of this Section
10(i), the Company shall not be required to effect any registrations under the
1933 Act or under any state securities laws on behalf of the Holder if, in the
opinion of counsel to the Company, the offering or transfer by such Holder in
the manner proposed (including, without limitation, the number of shares
proposed to be offered or transferred, the time of sale, and the method of
offering or transfer) is exempt from the registration requirements of the 1933
Act and the securities laws of applicable states and the Company consents to
such transfer, if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares


                                       12
<PAGE>   32


of securities of every other person subject to the foregoing restriction) until
the end of such period.

         12. Miscellaneous Provisions.

                  (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

                  (b) Replacement. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense will execute and deliver, in lieu of this
Warrant a new Warrant of like tenor.

                  (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

                  (d) Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

                  (e) Notices. All notices from the Company to the holder of
this Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized
reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to


                                       13
<PAGE>   33


have been given as provided above, whether by mail or by courier, as applicable,
if transmitted by telecopier, whichever shall first occur.


         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its duly authorized officer.

Dated:  August 13, 1999.

                        WARRANT TO PURCHASE COMMON STOCK
                       OF CHAPARRAL NETWORK STORAGE, INC.
                           Void after August 18, 2004

       This certifies that, subject to the terms and conditions set forth
herein, for value received, Michael J. Gluck, (the "Holder") or its registered
assigns is entitled to purchase from Chaparral Network Storage, Inc., a Delaware
corporation (the "Company") up to twenty thousand (20,000) fully paid and
nonassessable shares of Common Stock, $0.001 par value, of the Company (as
adjusted pursuant to Section 7 hereof, the "Shares") at the purchase price per
share specified in Section 2 below.

       1.     Definitions. As used in this Warrant, the following terms, unless
the context otherwise requires, have the following meanings:

              (a)    "Common Stock", when used with reference to stock of the
Company, means all shares, now or hereafter authorized, of the class of Common
Stock, $0.001 par value, of the Company currently authorized and shares of any
other class into which those shares may hereafter be changed.

              (b)    "Company" means Chaparral Network Storage, Inc. a Delaware
corporation and any corporation which shall succeed to or assume the obligations
of the Company under this Warrant.

              (c)    "1933 Act" means the Securities Act of 1933, as amended.

              (d)    "1934 Act" means the Securities Exchange Act of 1934, as
amended.

              (e)    "Convertible equity securities" or "equity securities"
shall mean any of the Company's securities.

              (f)    "Holder" means Sentinel Consulting, LLC, a Delaware

              (g)    The terms "register", "registered" and "registration" refer
to a registration effected by preparing and filing a registration statement or
similar document in compliance with

                                       1
<PAGE>   35

the 1933 Act, and the declaration or ordering of the effectiveness of such
registration statement or document by the SEC.

              (h)    The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

       2.     Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.125 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

       3.     Exercise Period. This Warrant shall be exercisable by the Holder
fora term beginning on August 19, 1999, (the "Commencement Date") and ending on
August 18, 2004, (the "Expiration Date").

       4.     Method of Exercise.

              (a)    The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                     (i)     the  surrender of the Warrant, together with a duly
executed copy of the form of subscription attached hereto as Appendix I, to the
Secretary of the Company at its principal offices; and

                     (ii)    the  payment to the  Company,  in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

              (b)    In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                           A

Where X= the number of Shares to be issued to the Holder.


                                       2
<PAGE>   36

         Y= the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A= the fair market value of one Share (at the date of such exercise).

         B= the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common Stock
         quoted in the NASDAQ National Market System or the Over-the-Counter
         market or the closing price quoted on any exchange on which the Common
         Stock is listed, whichever is applicable, as published in the Western
         Edition of The Wall Street Journal for the five (5) trading days prior
         to the date of determination of the fair market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

              (c)    Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

              (d)    In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

       5.     Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

       6.     Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into


                                       3
<PAGE>   37

Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

       7.     Adjustment of Warrant Price and Number of Shares. The number of
and kind of securities purchasable upon exercise of this Warrant and the
purchase price therefor shall be subject to adjustment from time to time as
follows:

              (a)    Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

              (b)    Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

              (c)    Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.


                                       4
<PAGE>   38

              (d)    Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

              (e)    No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

       8.     Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

       9.     Exercise, Transfer and Exchange Restrictions.

              (a)    This Warrant, and any rights hereunder, may not be
assigned or transferred, except as provided herein and in accordance with and
subject to the provisions of (i) applicable state securities laws, and (ii) the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (such Act and such rules and regulations being hereinafter
collectively referred to as the "Act"). Any purported transfer or assignment
made other than in accordance with this Section 9 shall be null and void and of
no force and effect.

              (b)    This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable


                                       5
<PAGE>   39
expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

              (c)    Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

       10.    Registration Rights.

              (a)    Requested Registration.

                     (i)   Request for Registration. In case the Company shall
receive from the Holder a written request that the Company file a registration
statement under the 1933 Act with respect to shares of Registrable Securities
having an expected aggregate offering price of at least One Million Dollars
($1,000,000), the Company will, subject to the limitations of Section 9(a)(ii),
use its best efforts to effect such registration under the 1933 Act (including,
without limitation, appropriate qualification under applicable blue sky or other
state securities laws and appropriate compliance with applicable regulations
issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                           (A)   In any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the 1933 Act;

                           (B)   Prior to the six (6) months after the closing
date of the Company's first registered public offering of its stock (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);

                           (C)   During the period starting with the date sixty
(60)days prior to the Company's estimated date of filing of, and ending on the
date six (6) months immediately following the closing date of, any initial
registration statement pertaining to securities of the Company (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); provided, however, that the Company is acting in good
faith and using all reasonable efforts to cause such initial registration
statement to become effective;


                                       6
<PAGE>   40

                           (D)   After the Company has effected one (1) such
registration pursuant to a Holder's demand under this Section 10(a)(i), which
registration has been declared effective; or

                           (E)   If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                     (ii)  Underwriting. In the event that a registration
pursuant to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

              (b)    Piggy-back Registration Rights.

                     (i) Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).


                                       7
<PAGE>   41

                     (ii)  Underwriting Requirements in Piggy-back Registration.
The right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

              (c)    Obligations of the Company. Whenever required under this
Section 9 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                     (i)   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 Holder, keep such registration statement effective for up to one hundred
twenty (120) days.

                     (ii)  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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                     (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                     (iv)  Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                     (v)   In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement with
terms generally satisfactory to the managing underwriter of such offering. The
Holder shall also enter into and perform its obligations under such an
agreement.


                                       8
<PAGE>   42

                     (vi)  Notify the Holder, at any time when a prospectus
relating thereto is required to be delivered under the 1933 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 light of the
circumstances then existing. In such instance, Company shall use its best
efforts to cure any such statement or omission so as to render such statement or
omission not misleading.

              (d)    Furnish Information. In connection with any action pursuant
to this Section 10, the 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 their Registrable Securities. In that connection, the Holder
shall be required to represent to the Company that all such information which is
given is both complete and accurate in all material respects when made.

              (e)    Definition of Expenses.

                     (i)   "Registration Expenses" shall mean all expenses
incurred by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                     (ii)  "Selling Expenses" shall mean all underwriting
discounts and selling commissions applicable to the sale of the Registrable
Securities in the registration, all stock transfer taxes and all fees and
disbursements of any additional special counsel (other than the special counsel
provided for in Section 10(e)(i) above) retained in connection with each such
registration by the Holder.

              (f)    Expenses of Registration. The Company shall bear all
Registration Expenses incurred in connection with (i) any registration,
qualification or compliance pursuant to Section 10(a), and (ii) no more than
three (3) registrations pursuant to Section 10(b). All Selling Expenses shall be
borne by the Holder.

              (g)    Indemnification.  In  the  event  any  Registrable
Securities are included in a registration statement under this Section 10:

                     (i)   To the extent permitted by law, the Company will
indemnify and hold harmless the Holder, the officers, directors and partners of
the Holder, any underwriter (as


                                       9
<PAGE>   43

defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                     (ii)  To the extent permitted by law, the Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who have signed the registration statement, each person, if any, who
controls the Company within the meaning of the 1933 Act, any underwriter (within
the meaning of the 1933 Act) for the Company, any person who controls such
underwriter, and any other security holder in such registration statement or any
of its partners, directors or officers or any person who controls such security
holder, against any losses, claims, damages or liabilities (joint or several) to
which any of the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity


                                       10
<PAGE>   44

agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                     (iii) Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                     (iv)  In order to provide for just and equitable
contribution to joint liability under the 1933 Act in any case in which either
(i) any indemnified party makes a claim under this Section 10(g) or any
controlling person of such indemnified party makes such a claim but is
judicially determined (by entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 10(g) provides for indemnification in
such case, or (ii) contribution under the 1933 Act may be required on the part
of any such person seeking indemnity under the terms of this Section 10(g);
then, and in each such case, the Company and such person will contribute to the
aggregate losses, claims, damages, or liabilities to which they may be subject
(after contribution from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent


                                       11
<PAGE>   45

misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

              (h)    Investor Rights Agreement. The Holder acknowledges and
agrees that (i) the Company and certain investors have entered into an Investor
Rights Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii)
the Holder may include his securities in a demand registration under the
Investor Rights Agreement only to the extent that the inclusion of his
securities will not reduce the amount of securities to be registered for parties
to the Investor Rights Agreement and (iii) the Holder shall not make a demand
registration which could result in such registration statement being declared
effective prior six months after the effective date of the Company's initial
public offering of securities pursuant to a registration filed under the 1933
Act or within one hundred twenty (120) days of the effective date of any demand
registration pursuant to the Investor Rights Agreement.

              (i)    Termination of Registration Rights.

                     (i)   The Company shall have no obligations pursuant to
Section 10 with respect to any request or requests made by the Holder after the
date which is five (5) years following the date of the consummation of the first
sale of securities pursuant to a registration statement filed by the Company
under the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                     (ii)  Notwithstanding any contrary provision of this
Section 10(i), the Company shall not be required to effect any registrations
under the 1933 Act or under any state securities laws on behalf of the Holder
if, in the opinion of counsel to the Company, the offering or transfer by such
Holder in the manner proposed (including, without limitation, the number of
shares proposed to be offered or transferred, the time of sale, and the method
of offering or transfer) is exempt from the registration requirements of the
1933 Act and the securities laws of applicable states and the Company consents
to such transfer, if required.

       11.    "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares

                                       12
<PAGE>   46

of securities of every other person subject to the foregoing restriction) until
the end of such period.

       12.    Miscellaneous Provisions.

              (a)    Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

              (b)    Replacement. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense will execute and deliver, in lieu of this
Warrant a new Warrant of like tenor.

              (c)    No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

              (d)    Governing  Law.  This  Warrant  shall be  governed  by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

              (e)    Notices. All notices from the Company to the holder of
this Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized
reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to


                                       13
<PAGE>   47

have been given as provided above, whether by mail or by courier, as applicable,
if transmitted by telecopier, whichever shall first occur.


         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed

                                        1
<PAGE>   49


                  (g) The terms "register", "registered" and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with the 1933 Act, and the
declaration or ordering of the effectiveness of such registration statement or
document by the SEC.

                  (h) The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

         2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.001 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

         3. Exercise Period. This Warrant shall be exercisable by the Holder for
a term beginning on December 15, 1998, (the "Commencement Date") and ending on
December 15, 2003, (the "Expiration Date").

         4. Method of Exercise.

                  (a) The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                           (i) the surrender of the Warrant, together with a
duly executed copy of the form of subscription attached hereto as Appendix I, to
the Secretary of the Company at its principal offices; and

                           (ii) the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

                  (b) In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                           A


                                       2
<PAGE>   50


Where X= the number of Shares to be issued to the Holder.
      Y= the number of Shares purchasable under this Warrant (at the date of
         such exercise).

      A= the fair market value of one Share (at the date of such exercise).

      B= the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

      (i) The average of the closing bid and asked prices of the Common Stock
      quoted in the NASDAQ National Market System or the Over-the-Counter market
      or the closing price quoted on any exchange on which the Common Stock is
      listed, whichever is applicable, as published in the Western Edition of
      The Wall Street Journal for the five (5) trading days prior to the date of
      determination of the fair market value; or

      (ii) If the Common Stock is not publicly traded, the per share fair market
      value of the Common Stock shall be determined in good faith by the
      Company's Board of Directors. If the Holder disagrees with the
      determination by the Board of Directors of the fair market value of the
      Common Stock then such fair market value shall be determined by an
      independent appraiser selected jointly by the Company and the Holder. The
      cost of such appraisal shall be paid equally by the Company and the
      Holder.

                  (c) Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

                  (c) In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of


                                       3
<PAGE>   51


this Warrant for the full number of Shares specified herein and the conversion
of the Shares into Common Stock. The Company further covenants that such Shares,
when issued pursuant to the exercise of this Warrant, will, upon issuance, be
duly and validly issued, fully paid and non-assessable and free from all taxes,
liens and charges with respect to the issuance thereof.

         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the purchase
price therefor shall be subject to adjustment from time to time as follows:

                  (a) Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

                  (b) Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

                  (c) Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.


                                       4
<PAGE>   52


                  (d) Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

                  (e) No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

         8. Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

         9. Exercise, Transfer and Exchange Restrictions.

                  (a) This Warrant, and any rights hereunder, may not be
assigned or transferred, except as provided herein and in accordance with and
subject to the provisions of (i) applicable state securities laws, and (ii) the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (such Act and such rules and regulations being hereinafter
collectively referred to as the "Act"). Any purported transfer or assignment
made other than in accordance with this Section 9 shall be null and void and of
no force and effect.

                  (b) This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer


                                       5
<PAGE>   53


or assignment, the assignor or transferor shall reimburse the Company for its
reasonable expenses, including transfer taxes and attorneys' fees, incurred in
connection with the transfer or assignment.

                  (c) Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

         10. Registration Rights.

                  (a) Requested Registration.

                           (i) Request for Registration. In case the Company
shall receive from the Holder a written request that the Company file a
registration statement under the 1933 Act with respect to shares of Registrable
Securities having an expected aggregate offering price of at least One Million
Dollars ($1,000,000), the Company will, subject to the limitations of Section
9(a)(ii), use its best efforts to effect such registration under the 1933 Act
(including, without limitation, appropriate qualification under applicable blue
sky or other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                                    (A) In any particular jurisdiction in which
the Company would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the Company
is already subject to service in such jurisdiction and except as may be required
by the 1933 Act;

                                    (B) Prior to the six (6) months after the
closing date of the Company's first registered public offering of its stock
(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);

                                    (C) During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good


                                       6
<PAGE>   54


faith and using all reasonable efforts to cause such initial registration
statement to become effective;

                                    (D) After the Company has effected one (1)
such registration pursuant to a Holder's demand under this Section 10(a)(i),
which registration has been declared effective; or

                                    (E) If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                  (ii) Underwriting. In the event that a registration pursuant
to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

         (b) Piggy-back Registration Rights.

                  (i) Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii),


                                       7
<PAGE>   55


use its best efforts to cause to be registered under the 1933 Act all of the
Registrable Securities that the Holder has requested to be registered. The
Company shall be required to effect not more than three (3) such registrations
of Registrable Securities pursuant to the request of the Holder under this
Section 10(b).

                  (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

         (c) Obligations of the Company. Whenever required under this Section 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                  (i)   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
Holder, keep such registration statement effective for up to one hundred twenty
(120) days.

                  (ii)  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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                  (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                  (iv)  Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such


                                       8
<PAGE>   56


expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                  (v)   In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement with terms
generally satisfactory to the managing underwriter of such offering. The Holder
shall also enter into and perform its obligations under such an agreement.

                  (vi)  Notify the Holder, at any time when a prospectus
relating thereto is required to be delivered under the 1933 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 light of the
circumstances then existing. In such instance, Company shall use its best
efforts to cure any such statement or omission so as to render such statement or
omission not misleading.

         (d) Furnish Information. In connection with any action pursuant to this
Section 10, the 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 their Registrable Securities. In that connection, the Holder shall be
required to represent to the Company that all such information which is given is
both complete and accurate in all material respects when made.

         (e) Definition of Expenses.

                  (i) "Registration Expenses" shall mean all expenses incurred
by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                  (ii) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of the Registrable Securities in
the registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

         (f) Expenses of Registration. The Company shall bear all Registration
Expenses incurred in connection with (i) any registration, qualification or
compliance pursuant to Section 10(a), and (ii) no more than three (3)
registrations pursuant to Section 10(b). All Selling Expenses shall be borne by
the Holder.


                                       9
<PAGE>   57


         (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:

                  (i) To the extent permitted by law, the Company will indemnify
and hold harmless the Holder, the officers, directors and partners of the
Holder, any underwriter (as defined in the 1933 Act) for the Holder and each
person, if any, who controls the Holder or underwriter within the meaning of the
1933 Act or the 1934 Act, against any losses, claims, damages, or liabilities
(joint or several) to which they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the 1933 Act, the 1934 Act or any state securities
law; and the Company will reimburse the Holder, officer, director or partner,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
Company's indemnity contained in this Section 10(g) 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 Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable 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 in writing and expressly stated
for use in connection with such registration by the Holder, or the Holder's
officers, directors or partners, underwriter, or controlling person. The Company
shall not be required to indemnify any person against any liability arising (i)
from any untrue or misleading statement or omission contained in any preliminary
prospectus if such deficiency is corrected in the final prospectus or (ii) out
of the failure of any person to deliver a prospectus as required by the 1993
Act. The indemnity provided for in this Section 10(g) shall remain in full force
and effect regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                  (ii) To the extent permitted by law, the Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other security holder in such registration statement or any of its partners,
directors or officers or any person who controls such security holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 Act, the 1934 Act or
other federal or state law, insofar as such


                                       10
<PAGE>   58


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 the Holder expressly stated in a writing for
use in connection with such registration; and the Holder will reimburse any
legal or other expenses, as incurred, where same are reasonably incurred by any
person intended to be indemnified pursuant to this Section 10(g), in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
Section 10(g) 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.
Notwithstanding the foregoing, the liability of each Holder under this Section
10(g) shall be limited to an amount equal to the public offering price of the
shares sold by the Holder.

                  (iii) Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                  (iv) In order to provide for just and equitable contribution
to joint liability under the 1933 Act in any case in which either (i) any
indemnified party makes a claim under this Section 10(g) or any controlling
person of such indemnified party makes such a claim but is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) 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


                                       11
<PAGE>   59


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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November 25, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the Investor
Rights Agreement and (iii) the Holder shall not make a demand registration which
could result in such registration statement being declared effective prior six
months after the effective date of the Company's initial public offering of
securities pursuant to a registration filed under the 1933 Act or within one
hundred twenty (120) days of the effective date of any demand registration
pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.

                  (i) The Company shall have no obligations pursuant to Section
10 with respect to any request or requests made by the Holder after the date
which is five (5) years following the date of the consummation of the first sale
of securities pursuant to a registration statement filed by the Company under
the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                  (ii) Notwithstanding any contrary provision of this Section
10(i), the Company shall not be required to effect any registrations under the
1933 Act or under any state securities laws on behalf of the Holder if, in the
opinion of counsel to the Company, the offering or transfer by such Holder in
the manner proposed (including, without limitation, the number of shares
proposed to be offered or transferred, the time of sale, and the method of
offering or transfer) is exempt from the registration requirements of the 1933
Act and the securities laws of applicable states and the Company consents to
such transfer, if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock


                                       12
<PAGE>   60


shares included in the registration) without the prior written consent of the
Company or such underwriters, as the case may be, for such period of time (not
to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares of securities of every
other person subject to the foregoing restriction) until the end of such period.

         12. Miscellaneous Provisions.

                  (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

                  (b) Replacement. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense will execute and deliver, in lieu of this
Warrant a new Warrant of like tenor.

                  (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

                  (d) Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

                  (e) Notices. All notices from the Company to the holder of
this Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized

                                       13
<PAGE>   61
reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to have been given
as provided above, whether by mail or by courier, as applicable, if transmitted
by telecopier, whichever shall first occur.

         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its duly authorized officer.

underwritten public offering registered under the 1933 Act, the public offering
price (before deducting commissions, discounts or expenses) per share sold in

hereof (such price, as adjusted from time to time, is herein referred ---------

         3. Exercise Period. This Warrant shall be exercisable by the Holder
for a term (the "Exercise Period") beginning at 8:00 a.m. Mountain Standard
Time on December 1, 2000 (the "Commencement Date") and ending at 5:00 p.m.
Mountain Standard Time on May 31, 2001 (the "Expiration Date").

         4. Method of Exercise.

            (a) The Holder may exercise the purchase rights evidenced hereby, in
whole or in part, during the Exercise Period. Such exercise shall be effected
by:

                (i) the surrender of the Warrant, together with a duly
            executed copy of the Subscription Notice, to the Secretary of the
            Company at its principal office; and

                (ii) the payment to the Company, by wire transfer of
            immediately available funds to an account designated by the Company
            at least two (2) days prior to the Commencement Date of an
            aggregate amount equal to the number of Shares designated for
            purchase in the completed Subscription Notice multiplied by the
            Warrant Price.

         (b) If the Holder believes that the exercise of this Warrant will
necessitate a filing under the HSR Act, the Holder shall give the Company at
least thirty (30) but not more than ninety




                                      -2-
<PAGE>   64
(90) days written notice of Holder"s intent to exercise this Warrant. As
promptly as practicable after the giving of such notice, the Company and the
Holder shall make all filings required by the HSR Act.

         (c) Upon the request of the Company, the Holder shall also deliver to
the Company an instrument, in form and substance reasonably satisfactory to
counsel for the Company, executed by the Holder certifying that the Shares are
being acquired for investment purposes only and not with a view to their resale
or distribution.

         (d) This Warrant and all rights of the Holder to purchase Shares
hereunder shall terminate and become void at the Expiration Date.

         (e) Net Exercise Election. The Holder may elect to convert all or a
portion of this Warrant, without the payment by the Holder of any additional
consideration, by the surrender of this Warrant or such portion of this Warrant
to the Company, with the net exercise election selected in the Notice of
Exercise attached hereto as Appendix II duly executed by the Holder, into up to
the number of Shares that is obtained under the following formula:

                                  X = Y (A-B)
                                    --------
                                       A

where X =         the number of shares to be issued to the Holder.

                  Y = the number of Shares as to which this Warrant is being
                      exercised.

                  A = the fair market value of one Share, as determined in good
                      faith by the Company's Board of Directors, as at the time
                      the net exercise election is made.

                  B = the Warrant Price.

         The Company will promptly respond in writing to an inquiry by the
Holder as to the then current fair market value of one Share.

         For purposes of the above calculation, fair market value of one Share
shall be determined by the Company's Board of Directors in good faith;
provided, however, that where there exists a public market for the Company's
Common Stock at the time of such exercise, the fair market value per share
shall be the average of the closing bid and asked prices of the Common Stock
quoted in the Over-The-Counter Market Summary or the last reported sale price
of the Common Stock or the closing price quoted on the Nasdaq National Market
or on any exchange on which the Common Stock is listed, whichever is
applicable, as published in the Western Edition of The Wall Street Journal for
the three (3) trading days prior to the date of determination of fair market
value.




                                      -3-
<PAGE>   65



         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable, and
in any event within ten (10) days, after receipt by the Company of the
completed Subscription Notice and payment for the Shares being purchased. The
Company shall not be required to issue any fractional shares upon the exercise
of the Holder"s purchase rights under this Warrant. In lieu of any fractional
shares, the Company shall pay cash equal to such fraction multiplied by the per
share Fair Market Value of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Common Stock, free
from all preemptive rights with respect thereto, as will be sufficient to
permit the exercise of this Warrant for the purchase of the full number of
Shares specified herein. The Company further covenants that such Shares, when
issued pursuant to the exercise of this Warrant, will, upon issuance, be duly
and validly issued, fully paid and non-assessable and free from all taxes,
liens and charges with respect to the issuance thereof.

         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the Warrant
Price therefor shall be subject to adjustment from time to time as follows:

            (a) Stock Splits, Stock Dividends and Combinations. If the Company
shall at any time subdivide or combine its outstanding shares of the Common
Stock, or shall make or issue a dividend or other distribution payable in
additional shares of Common Stock, this Warrant shall, after that subdivision,
combination or dividend, evidence the right to purchase the number of shares of
Common Stock that would have been issuable as a result of that change with
respect to the shares of the Common Stock which were purchasable under this
Warrant immediately before that subdivision or combination. If the Company
shall at any time subdivide the outstanding shares of Common Stock, or shall
make or issue a dividend or other distribution payable in additional shares of
Common Stock, the Warrant Price then in effect immediately before that
subdivision or dividend shall be proportionately decreased, and, if the Company
shall at any time combine the outstanding shares of Common Stock, the Warrant
Price then in effect immediately before that combination shall be
proportionately increased. Any adjustment under this Section 7(a) shall become
effective at the close of business on the date the subdivision or combination
becomes effective.

           (b) Reclassification, Exchange and Substitution. If the Common Stock
issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common
Stock which the Holder would have become entitled to purchase but for such
change, a number of shares of such other series or class or classes of stock
equivalent to the number of shares of Common Stock that would have been subject
to purchase by the Holder on exercise of this Warrant immediately before that
change.



                                      -4-
<PAGE>   66



           (c) Reorganization. If at any time there shall be a capital
reorganization of the Company (other than a combination, reclassification,
exchange, or subdivision of shares provided for elsewhere in this Warrant),
then, as a part of such capital reorganization, lawful provision shall be made
so that the Holder of this Warrant shall thereafter be entitled to receive upon
exercise of this Warrant, during the period specified in this Warrant and upon
payment of the Warrant Price then in effect, the number of shares of stock or
other securities or property of the Company or its successor to which a holder
of the Company"s Common Stock deliverable upon exercise of this Warrant would
have been entitled in such capital reorganization if this Warrant had been
exercised immediately before that capital reorganization.

           (d) Adjustments for Dividends and Other Distributions. If the
Company at any time or from time to time makes or fixes a record date for the
determination of holders of Common Stock entitled to received any distribution
(excluding any repurchases of securities by the Company not made on a pro rata
basis from all holders of any class of the Company securities) payable in
property other than cash or in securities of the Company, then and in each such
event the Holder of this Warrant shall receive at the time of the exercise of
this Warrant, the amount of property or the number of securities of the Company
that the Holder would have received had it exercised this Warrant on such
record date, in addition to the Shares.

           (e) Notice of Adjustments. The Company shall give notice of each
adjustment or readjustment of the number of shares of the Common Stock or other
securities issuable upon exercise of this Warrant and the Warrant Price to the
registered Holder of this Warrant at that Holder"s address as shown on the
Company"s books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

           (f) No Change Necessary. The form of this Warrant need not be changed
because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment, provided that an appropriate notation to this effect
is made on such Warrant.

         8. Merger, Consolidation or Sale of Assets.

           (a) If the Company consolidates with or merges into another entity
and is not the survivor, or sells or conveys substantially all of its property,
and in connection therewith, shares of stock, other securities, property, or
cash (collectively, "Merger Consideration") are issuable or deliverable in
exchange for shares of the Company"s capital stock, then the Company shall give
the Holder at least thirty (30) days prior written notice of the consummation
of such transaction and the Holder may thereafter, at its option, (i) exercise
the Warrant, regardless of whether this Warrant is exercisable at the time of
such action, or (ii) require the Company or its successor or purchaser to



                                      -5-
<PAGE>   67




enter into an agreement with the Holder to the effect that the Holder shall
have the right thereafter, upon payment of the Warrant Price in effect
immediately prior to such action, to purchase upon exercise of this Warrant the
Merger Consideration (subject to adjustment as provided in this Warrant) that
the Holder would have received had the Holder exercised this Warrant in its
entirety immediately prior to such merger, sale or conveyance, regardless of
whether this Warrant is exercisable at the time of such action.

           (b) If the Company receives notice that a purchase, tender or
exchange offer has been made to the holders of more than 50% of the outstanding
Common Stock (on an as converted basis), the Company shall give the Holder
reasonable notice thereof, and the Holder shall be entitled to exercise this
Warrant immediately, regardless of whether this Warrant is exercisable at the
time of such offer and without giving the Company the notice required by
Section 4(b).

         9. Notice of Certain Events. If (a) the Company authorizes the
issuance to all holders of any class of its capital stock rights or warrants to

liquidation or merger to which the Company is a party and for which approval of

reclassification or change of the shares of Common Stock issuable upon the
exercise of this Warrant; (e) the Board of Directors of the Company approves
the conveyance or transfer of the all or substantially all of the Company"s
properties and assets; or (f) the Board of Directors of the Company approves

be mailed by certified mail to the Holder, at least thirty (30) days prior to
the applicable record or effective date hereinafter specified, a notice stating
the dates as of which (x) the holders of capital stock of record to be entitled
to receive any such rights, warrants or distributions or to be entitled to vote
on such Notice Event are to be determined and (y) such Notice Event is expected
to become effective. The Holder of record of this Warrant shall be entitled to
exercise of this Warrant upon the consummation of such Notice Event, regardless
of whether this Warrant is exercisable at the time of such action.

         10. Exercise, Transfer and Exchange Restrictions.

             (a) This Warrant, and any rights hereunder, may not be sold,

                        WARRANT TO PURCHASE COMMON STOCK
                         OF CHAPARRAL TECHNOLOGIES, INC.
                           Void after February 8, 2004

    This certifies that, subject to the terms and conditions set forth herein,
for value received, Sentinel Consulting LLC., a Delaware corporation, (the
"Holder") or its registered assigns is entitled to purchase from Chaparral
Technologies, Inc., a Delaware corporation (the "Company") up to one hundred

$0.001 par value, of the Company (as adjusted pursuant to Section 7 hereof, the
"Shares") at the purchase price per share specified in Section 2 below.

    1. Definitions. As used in this Warrant, the following terms, unless the
context otherwise requires, have the following meanings:

         (a) "Common Stock", when used with reference to stock of the Company,
means all shares, now or hereafter authorized, of the class of Common Stock,
$0.001 par value, of the Company currently authorized and shares of any other
class into which those shares may hereafter be changed.

         (b) "Company" means Chaparral Technologies, Inc. a Delaware corporation
and any corporation which shall succeed to or assume the obligations of the
Company under this Warrant.

         (c) "1933 Act" means the Securities Act of 1933, as amended.

         (d) "1934 Act" means the Securities Exchange Act of 1934, as amended.

         (e) "Convertible equity securities" or "equity securities" shall mean

         (f) "Holder" means Sentinel Consulting, LLC, a Delaware corporation.

         (g) The terms "register", "registered" and "registration" refer to a

similar document in compliance with the 1933 Act, and the declaration or
ordering of the effectiveness of such registration statement or document by the
SEC.


                                       1
<PAGE>   71


         (h) The term "Registrable Securities" means: (i) the Common Stock or
other equity or convertible equity securities of the Company issued or issuable
upon exercise of this Warrant; and (ii) any Common Stock of the Company issued
(or issuable upon the conversion or exercise of any warrant, right or other
security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

    2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.25 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

    3. Exercise Period. This Warrant shall be exercisable by the Holder for a
term beginning on February 8. 1999, (the "Commencement Date") and ending on
February 8, 2004, (the "Expiration Date").

    4. Method of Exercise.

         (a) The Holder may exercise from time to time, in whole or in part on
or before the Expiration Date, the purchase rights evidenced hereby. Such
exercise shall be effected by:

              (i) the surrender of the Warrant, together with a duly executed
copy of the form of subscription attached hereto as Appendix I, to the Secretary
of the Company at its principal offices; and

              (ii) the payment to the Company, in cash or by check payable to
the order of the Company, of an amount equal to the aggregate purchase price for
the number of Shares designated for purchase in the completed subscription form.

         (b) In lieu of exercising this Warrant pursuant to Section 4(a), the
Holder may elect to receive shares equal to the value of this Warrant (or any
portion thereof remaining unexercised) by surrender of this Warrant at the
principal office of the Company together with the Subscription Form, in which
event the Company shall issue to the Holder a number of Shares computed using
the following formula:

                  X = Y (A-B)
                     --------
                       A

Where X= the number of Shares to be issued to the Holder.



                                       2
<PAGE>   72
    Y=the number of Shares purchasable under this Warrant (at the date of such
    exercise).

    A=the fair market value of one Share (at the date of such exercise).

    B=the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:



    (i) The average of the closing bid and asked prices of the Common Stock
    quoted in the NASDAQ National Market System or the Over-the-Counter market
    or the closing price quoted on any exchange on which the Common Stock is
    listed, whichever is applicable, as published in the Western Edition of The
    Wall Street Journal for the five (5) trading days prior to the date of
    determination of the fair market value; or

    (ii) If the Common Stock is not publicly traded, the per share fair market
    value of the Common Stock shall be determined in good faith by the Company's
    Board of Directors. If the Holder disagrees with the determination by the
    Board of Directors of the fair market value of the Common Stock then such
    fair market value shall be determined by an independent appraiser selected
    jointly by the Company and the Holder. The cost of such appraisal shall be
    paid equally by the Company and the Holder.

         (c) Upon the request of the Company, the Holder shall also deliver to
the Company an instrument, in form and substance reasonably satisfactory to
counsel for the Company, executed by the Holder certifying that the Shares are
being acquired for investment purposes only and not with a view to their resale
or distribution.

         (c) In the event of a partial exercise of this Warrant, a new Warrant
shall be issued to the Holder representing the balance of the Shares purchasable
under this Warrant, such new Warrant to be issued within ten (10) days after
delivery of the subscription notice.

     5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

    6. Reservation of Shares. The Company covenants that it will at all times
keep available such number of authorized shares of its Series A Preferred Stock
and Common Stock, free from all preemptive rights with respect thereto, as will
be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into


                                       3
<PAGE>   73


Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

    7. Adjustment of Warrant Price and Number of Shares. The number of and kind
of securities purchasable upon exercise of this Warrant and the purchase price
therefor shall be subject to adjustment from time to time as follows:

         (a) Stock Splits and Combinations. If the Company shall at any time
subdivide or combine its outstanding shares of the Common Stock, this Warrant
shall, after that subdivision or combination, evidence the right to purchase the
number of shares of Common Stock that would have been issuable as a result of
that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

         (b) Reclassification, Exchange and Substitution. If the Common Stock
issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

         (c) Reorganization, Mergers, Consolidations or Sale of Assets. If at
any time there shall be a capital reorganization of the Company (other than a
combination, reclassification, exchange, or subdivision of shares provided for
elsewhere in this Warrant) or merger or consolidation of the Company with or
into another corporation, or the sale of the Company's properties and assets as,
or substantially as, an entirety to any other person, then, as a part of such
capital reorganization, merger, consolidation or sale, lawful provision shall be
made so that the Holder of this Warrant shall thereafter be entitled to receive
upon exercise of this Warrant, during the period specified in this Warrant and
upon payment of the Warrant Price then in effect, the number of shares of stock
or other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Company's
Common Stock deliverable upon exercise of this Warrant would have been entitled
in such capital reorganization, merger, consolidation or sale if this Warrant
had been exercised immediately before that capital reorganization, merger,
consolidation or sale.


                                       4
<PAGE>   74


         (d) Notice of Adjustments. The Company shall give notice of each
adjustment or readjustment of the number of shares of the Common Stock or other
securities issuable upon exercise of this Warrant and the Warrant Price to the
registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

         (e) No Change Necessary. The form of this Warrant need not be changed
because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

    8. Automatic Termination. In the event of (i) the closing of the Company's
registration statement on a Form S-1 (or any other form equivalent thereto)
pursuant to which any class of the Company's securities is sold to the public in
a public offering registered under the Securities Act of 1933, as amended; or
(ii) the proposed sale of all or substantially all the capital stock, or
substantially all the assets, of the Company in a merger, business combination,
or other form of business transaction with or into a third party in which the
Company's stockholders do not own at least a majority of the outstanding voting
securities of the surviving corporation or business entity after such
transaction (based solely on such Company stockholders' holdings of the Company
prior to the transaction), then the Company shall give the Holder of this
Warrant at least fifteen (15) days written notice of the proposed effective date
and terms of such offering, transaction or agreements, and if the Warrant has
not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

    9. Exercise, Transfer and Exchange Restrictions.

         (a) This Warrant, and any rights hereunder, may not be assigned or
transferred, except as provided herein and in accordance with and subject to the
provisions of (i) applicable state securities laws, and (ii) the Securities Act
of 1933, as amended, and the rules and regulations promulgated thereunder (such
Act and such rules and regulations being hereinafter collectively referred to as
the "Act"). Any purported transfer or assignment made other than in accordance
with this Section 9 shall be null and void and of no force and effect.

         (b) This Warrant, and any rights hereunder, may be transferred or
assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable expenses, including transfer taxes and attorneys'
fees, incurred in connection with the transfer or assignment.


                                       5
<PAGE>   75


         (c) Any assignment permitted hereunder shall be made by surrender of
this Warrant to the Company at its principal office with an assignment duly
executed and funds sufficient to pay any transfer tax. In such event, the
Company shall, without charge, execute and deliver a new Warrant in the name of
the assignee named in such instrument of assignment and this Warrant shall be
promptly canceled.

    10. Registration Rights.

         (a) Requested Registration.

              (i) Request for Registration. In case the Company shall receive
from the Holder a written request that the Company file a registration statement
under the 1933 Act with respect to shares of Registrable Securities having an
expected aggregate offering price of at least One Million Dollars ($1,000,000),
the Company will, subject to the limitations of Section 9(a)(ii), use its best
efforts to effect such registration under the 1933 Act (including, without
limitation, appropriate qualification under applicable blue sky or other state
securities laws and appropriate compliance with applicable regulations issued
under the 1933 Act and any other governmental requirements or regulations) as
may be so requested and as would permit or facilitate the sale and distribution
of all or such portion of such Registrable Securities as are specified in such
request; provided, however, that the Company shall not be obligated to take any
action to effect any such registration, qualification or compliance pursuant to
this Section 10(a)(i):

                   (A) In any particular jurisdiction in which the Company would
be required to execute a general consent to service of process in effecting such
registration, qualification or compliance unless the Company is already subject
to service in such jurisdiction and except as may be required by the 1933 Act;

                   (B) Prior to the six (6) months after the closing date of the
Company's first registered public offering of its stock (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);

                   (C) During the period starting with the date sixty (60) days
prior to the Company's estimated date of filing of, and ending on the date six
(6) months immediately following the closing date of, any initial registration
statement pertaining to securities of the Company (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); provided, however, that the Company is acting in good faith and
using all reasonable efforts to cause such initial registration statement to
become effective;


                                       6
<PAGE>   76


                   (D) After the Company has effected one (1) such registration
pursuant to a Holder's demand under this Section 10(a)(i), which registration
has been declared effective; or

                   (E) If the Company shall furnish to Holder a certificate
signed by the President of the Company stating that in the good faith judgment
of the Board of Directors it would be seriously detrimental to the Company and
its shareholders for a registration statement to be filed at such time, then the
Company's obligation to use its best efforts to register, qualify or comply
under this Section 10(a)(i) shall be deferred for a period not to exceed one
hundred twenty (120) days from the date of receipt of written request from the
Holder; provided, however, that the Company may not make such certification more
than once every twelve (12) months.

              (ii) Underwriting. In the event that a registration pursuant to
Section 10(a)(i) is for a registered public offering involving an underwriting,
the Company shall so advise the Holder and the right of the Holder to
registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

         (b) Piggy-back Registration Rights.

              (i) Piggy-back Registration Rights. 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 Holder) any
of its securities under the 1933 Act in connection with the public offering of
such securities solely for cash (other than a registration (i) on Form S-8 or
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 (ii) with respect to an employee benefit plan, or
(iii) solely in connection with a Rule 145 transaction under the 1933 Act), the
Company shall, each such time, promptly give the Holder written notice of such
registration together with a list of the jurisdictions in which the Company
intends to attempt to qualify such securities under applicable state securities
laws. Upon the written request of the Holder given within twenty (20) business
days after delivery of such written notice by the Company, the Company shall,
subject to the provisions of Section 10(b)(ii), use its best efforts to cause to
be registered under the 1933 Act all of the Registrable Securities that the
Holder has requested to be registered. The Company shall be required to effect
not more than three (3) such registrations of Registrable Securities pursuant to
the request of the Holder under this Section 10(b).

              (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

         (c) Obligations of the Company. Whenever required under this Section 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

              (i) 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 Holder,
keep such registration statement effective for up to one hundred twenty (120)
days.

              (ii) 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
1933 Act with respect to the disposition of all securities covered by such
registration statement.

              (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

              (iv) Use its best efforts to register and qualify the securities
covered by such registration statement under the securities laws of such
jurisdictions as shall be reasonably appropriate for the distribution of the
securities covered by the registration statement; provided, however, that the
Company shall not be required in connection therewith or as a condition thereto
to qualify to do business or to file a general consent to service of process in
any such jurisdiction, and further provided that (anything in this Agreement to
the contrary notwithstanding with respect to the bearing of expenses) if any
jurisdiction in which the securities shall be qualified shall require that
expenses incurred in connection with the qualification of the securities in that
jurisdiction be borne by selling shareholders, then such expenses shall be
payable by the Holder, to the extent required by such jurisdiction if the Holder
does elect to withdraw from the registration after notice of such requirement.



                                       8
<PAGE>   78

              (v) In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement with terms generally
satisfactory to the managing underwriter of such offering. The Holder shall also
enter into and perform its obligations under such an agreement.

              (vi) Notify the Holder, at any time when a prospectus relating
thereto is required to be delivered under the 1933 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 light of the circumstances then
existing. In such instance, Company shall use its best efforts to cure any such
statement or omission so as to render such statement or omission not misleading.

         (d) Furnish Information. In connection with any action pursuant to this
Section 10, the 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 their Registrable Securities. In that connection, the Holder shall be
required to represent to the Company that all such information which is given is
both complete and accurate in all material respects when made.

         (e) Definition of Expenses.

              (i) "Registration Expenses" shall mean all expenses incurred by
the Company in complying with Section 10 hereof, including, without limitation,
all registration, filing and qualification fees, underwriters' expense
allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

              (ii) "Selling Expenses" shall mean all underwriting discounts and
selling commissions applicable to the sale of the Registrable Securities in the
registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

         (f) Expenses of Registration. The Company shall bear all Registration
Expenses incurred in connection with (i) any registration, qualification or
compliance pursuant to Section 10(a), and (ii) no more than three (3)
registrations pursuant to Section 10(b). All Selling Expenses shall be borne by
the Holder.

         (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:



                                        9
<PAGE>   79


              (i) To the extent permitted by law, the Company will indemnify and
hold harmless the Holder, the officers, directors and partners of the Holder,
any underwriter (as defined in the 1933 Act) for the Holder and each person, if
any, who controls the Holder or underwriter within the meaning of the 1933 Act
or the 1934 Act, against any losses, claims, damages, or liabilities (joint or
several) to which they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any state securities law or any rule or
regulation promulgated under the 1933 Act, the 1934 Act or any state securities
law; and the Company will reimburse the Holder, officer, director or partner,
underwriter or controlling person for any legal or other expenses reasonably
incurred by them, as incurred, in connection with investigating or defending any
such loss, claim, damage, liability, or action; provided, however, that the
Company's indemnity contained in this Section 10(g) 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 Company (which consent shall
not be unreasonably withheld), nor shall the Company be liable 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 in writing and expressly stated
for use in connection with such registration by the Holder, or the Holder's
officers, directors or partners, underwriter, or controlling person. The Company
shall not be required to indemnify any person against any liability arising (i)
from any untrue or misleading statement or omission contained in any preliminary
prospectus if such deficiency is corrected in the final prospectus or (ii) out
of the failure of any person to deliver a prospectus as required by the 1993
Act. The indemnity provided for in this Section 10(g) shall remain in full force
and effect regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

              (ii) To the extent permitted by law, the Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers who have
signed the registration statement, each person, if any, who controls the Company
within the meaning of the 1933 Act, any underwriter (within the meaning of the
1933 Act) for the Company, any person who controls such underwriter, and any
other security holder in such registration statement or any of its partners,
directors or officers or any person who controls such security holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity


                                       10
<PAGE>   80


agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

              (iii) Promptly after receipt by an indemnified party under this
Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

              (iv) In order to provide for just and equitable contribution to
joint liability under the 1933 Act in any case in which either (i) any
indemnified party makes a claim under this Section 10(g) or any controlling
person of such indemnified party makes such a claim but is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November 25, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the Investor
Rights Agreement and (iii) the Holder shall not make a demand registration which
could result in such registration statement being declared effective prior six
months after the effective date of the Company's initial public offering of
securities pursuant to a registration filed under the 1933 Act or within one
hundred twenty (120) days of the effective date of any demand registration
pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.

              (i) The Company shall have no obligations pursuant to Section 10
with respect to any request or requests made by the Holder after the date which
is five (5) years following the date of the consummation of the first sale of
securities pursuant to a registration statement filed by the Company under the
1933 Act in connection with the initial firm commitment underwritten offering of
its securities to the general public.

              (ii) Notwithstanding any contrary provision of this Section 10(i),
the Company shall not be required to effect any registrations under the 1933 Act
or under any state securities laws on behalf of the Holder if, in the opinion of
counsel to the Company, the offering or transfer by such Holder in the manner
proposed (including, without limitation, the number of shares proposed to be
offered or transferred, the time of sale, and the method of offering or
transfer) is exempt from the registration requirements of the 1933 Act and the
securities laws of applicable states and the Company consents to such transfer,
if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares of securities of every
other person subject to the foregoing restriction) until the end of such period.

         12. Miscellaneous Provisions.

              (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

              (b) Replacement. On receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant and,
in the case of loss, theft or destruction, on delivery of any indemnity
agreement or bond reasonably satisfactory in form and amount to the Company or,
in the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense will execute and deliver, in lieu of this Warrant a new
Warrant of like tenor.

              (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

              (d) Governing Law. This Warrant shall be governed by and construed
and enforced in accordance with the laws of the State of California applicable
to contracts entered into and wholly to be performed in California by California
residents.

              (e) Notices. All notices from the Company to the holder of this
Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized

its duly authorized officer.

                            Void after March 31, 2004

         This certifies that, subject to the terms and conditions set forth

         1. Definitions. As used in this Warrant, the following terms, unless

                  (a) "Common Stock", when used with reference to stock of the

refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with



                                       1
<PAGE>   84
the 1933 Act, and the declaration or ordering of the effectiveness of such
registration statement or document by the SEC.

                  (h) The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or

for, or in replacement of, such Common Stock.

         2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.36 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

         3. Exercise Period. This Warrant shall be exercisable by the Holder for
a term beginning on March 31. 1999, (the "Commencement Date") and ending on
March 31, 2004, (the "Expiration Date").

         4. Method of Exercise.

                  (a) The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                           (i) the surrender of the Warrant, together with a
duly executed copy of the form of subscription attached hereto as Appendix I, to
the Secretary of the Company at its principal offices; and

                           (ii) the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

                  (b) In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                          A

Where X= the number of Shares to be issued to the Holder.



                                       2
<PAGE>   85
         Y= the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A= the fair market value of one Share (at the date of such exercise).

         B= the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common Stock
         quoted in the NASDAQ National Market System or the Over-the-Counter
         market or the closing price quoted on any exchange on which the Common
         Stock is listed, whichever is applicable, as published in the Western
         Edition of The Wall Street Journal for the five (5) trading days prior
         to the date of determination of the fair market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

                  (c) Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

                  (d) In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into



                                       3
<PAGE>   86
Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the purchase
price therefor shall be subject to adjustment from time to time as follows:

                  (a) Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

                  (b) Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

                  (c) Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.



                                       4
<PAGE>   87
                  (d) Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

                  (e) No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

         8. Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

         9. Exercise, Transfer and Exchange Restrictions.

                  (a) This Warrant, and any rights hereunder, may not be
assigned or transferred, except as provided herein and in accordance with and
subject to the provisions of (i) applicable state securities laws, and (ii) the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (such Act and such rules and regulations being hereinafter
collectively referred to as the "Act"). Any purported transfer or assignment
made other than in accordance with this Section 9 shall be null and void and of
no force and effect.

                  (b) This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable



                                       5
<PAGE>   88
expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

                  (c) Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

         10. Registration Rights.

                  (a) Requested Registration.

                           (i) Request for Registration. In case the Company
shall receive from the Holder a written request that the Company file a
registration statement under the 1933 Act with respect to shares of Registrable
Securities having an expected aggregate offering price of at least One Million
Dollars ($1,000,000), the Company will, subject to the limitations of Section
9(a)(ii), use its best efforts to effect such registration under the 1933 Act
(including, without limitation, appropriate qualification under applicable blue
sky or other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                                    (A) In any particular jurisdiction in which
the Company would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the Company
is already subject to service in such jurisdiction and except as may be required
by the 1933 Act;

                                    (B) Prior to the six (6) months after the
closing date of the Company's first registered public offering of its stock
(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);

                                    (C) During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good faith and using all reasonable efforts to cause such initial
registration statement to become effective;



                                       6
<PAGE>   89
                                    (D) After the Company has effected one (1)
such registration pursuant to a Holder's demand under this Section 10(a)(i),
which registration has been declared effective; or

                                    (E) If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                  (ii) Underwriting. In the event that a registration pursuant
to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

         (b) Piggy-back Registration Rights.

                  (i) Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).



                                       7
<PAGE>   90
                  (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

         (c) Obligations of the Company. Whenever required under this Section 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                  (i) 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
Holder, keep such registration statement effective for up to one hundred twenty
(120) days.

                  (ii) 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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                  (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                  (iv) Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                  (v) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement with terms
generally satisfactory to the managing



                                       8
<PAGE>   91
underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                  (vi) Notify the Holder, at any time when a prospectus relating
thereto is required to be delivered under the 1933 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 light of the circumstances then
existing. In such instance, Company shall use its best efforts to cure any such
statement or omission so as to render such statement or omission not misleading.

         (d) Furnish Information. In connection with any action pursuant to this
Section 10, the 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 their Registrable Securities. In that connection, the Holder shall be
required to represent to the Company that all such information which is given is
both complete and accurate in all material respects when made.

         (e) Definition of Expenses.

                  (i) "Registration Expenses" shall mean all expenses incurred
by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                  (ii) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of the Registrable Securities in
the registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

         (f) Expenses of Registration. The Company shall bear all Registration
Expenses incurred in connection with (i) any registration, qualification or
compliance pursuant to Section 10(a), and (ii) no more than three (3)
registrations pursuant to Section 10(b). All Selling Expenses shall be borne by
the Holder.

         (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:

                  (i) To the extent permitted by law, the Company will indemnify
and hold harmless the Holder, the officers, directors and partners of the
Holder, any underwriter (as



                                       9
<PAGE>   92
defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                  (ii) To the extent permitted by law, the Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other security holder in such registration statement or any of its partners,
directors or officers or any person who controls such security holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity



                                       10
<PAGE>   93
agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                  (iii) Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                  (iv) In order to provide for just and equitable contribution
to joint liability under the 1933 Act in any case in which either (i) any
indemnified party makes a claim under this Section 10(g) or any controlling
person of such indemnified party makes such a claim but is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent



                                       11
<PAGE>   94
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November 25, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the Investor
Rights Agreement and (iii) the Holder shall not make a demand registration which
could result in such registration statement being declared effective prior six
months after the effective date of the Company's initial public offering of
securities pursuant to a registration filed under the 1933 Act or within one
hundred twenty (120) days of the effective date of any demand registration
pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.

                  (i) The Company shall have no obligations pursuant to Section
10 with respect to any request or requests made by the Holder after the date
which is five (5) years following the date of the consummation of the first sale
of securities pursuant to a registration statement filed by the Company under
the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                  (ii) Notwithstanding any contrary provision of this Section
10(i), the Company shall not be required to effect any registrations under the
1933 Act or under any state securities laws on behalf of the Holder if, in the
opinion of counsel to the Company, the offering or transfer by such Holder in
the manner proposed (including, without limitation, the number of shares
proposed to be offered or transferred, the time of sale, and the method of
offering or transfer) is exempt from the registration requirements of the 1933
Act and the securities laws of applicable states and the Company consents to
such transfer, if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares



                                       12
<PAGE>   95
of securities of every other person subject to the foregoing restriction) until
the end of such period.

         12. Miscellaneous Provisions.

                  (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

                  (b) Replacement. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense will execute and deliver, in lieu of this
Warrant a new Warrant of like tenor.

                  (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

                  (d) Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

                  (e) Notices. All notices from the Company to the holder of
this Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized
reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to

have been given as provided above, whether by mail or by courier, as applicable,
if transmitted by telecopier, whichever shall first occur.


         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its duly authorized officer.

                            Void after April 27, 2004

         This certifies that, subject to the terms and conditions set forth

(the "Holder") or its registered assigns is entitled to purchase from Chaparral

Common Stock, $0.001 par value, of the Company (as adjusted pursuant to Section
7 hereof, the "Shares") at the purchase price per share specified in Section 2
below.

         1. Definitions. As used in this Warrant, the following terms, unless
the context otherwise requires, have the following meanings:

                  (a) "Common Stock", when used with reference to stock of the
Company, means all shares, now or hereafter authorized, of the class of Common

other class into which those shares may hereafter be changed.

of the Company under this Warrant.

                  (c) "1933 Act" means the Securities Act of 1933, as amended.

                  (d) "1934 Act" means the Securities Exchange Act of 1934, as

                                       1
<PAGE>   98

                  (h) The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

         2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.38 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

         3. Exercise Period. This Warrant shall be exercisable by the Holder for
a term beginning on April 28. 1999, (the "Commencement Date") and ending on
April 27, 2004, (the "Expiration Date").

         4. Method of Exercise.


                  (a) The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                           (i) the surrender of the Warrant, together with a
duly executed copy of the form of subscription attached hereto as Appendix I, to
the Secretary of the Company at its principal offices; and

                           (ii) the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

                  (b) In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                          A

Where X= the number of Shares to be issued to the Holder.



                                       2
<PAGE>   99





         Y= the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A= the fair market value of one Share (at the date of such exercise).

         B= the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common Stock
         quoted in the NASDAQ National Market System or the Over-the-Counter
         market or the closing price quoted on any exchange on which the Common
         Stock is listed, whichever is applicable, as published in the Western
         Edition of The Wall Street Journal for the five (5) trading days prior
         to the date of determination of the fair market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

                     (c) Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

                     (c) In the event of a partial exercise of this Warrant, a
new Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into

                                       3
<PAGE>   100

Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.


         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the purchase
price therefor shall be subject to adjustment from time to time as follows:

                  (a) Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

                  (b) Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

                  (c) Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.

                                       4
<PAGE>   101

                  (d) Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

                  (e) No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

         8. Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

         9. Exercise, Transfer and Exchange Restrictions.

                  (a) This Warrant, and any rights hereunder, may not be
assigned or transferred, except as provided herein and in accordance with and
subject to the provisions of (i) applicable state securities laws, and (ii) the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (such Act and such rules and regulations being hereinafter
collectively referred to as the "Act"). Any purported transfer or assignment
made other than in accordance with this Section 9 shall be null and void and of
no force and effect.

                  (b) This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable

                                       5
<PAGE>   102

expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

                  (c) Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

         10. Registration Rights.


                  (a) Requested Registration.


                           (i) Request for Registration. In case the Company
shall receive from the Holder a written request that the Company file a
registration statement under the 1933 Act with respect to shares of Registrable
Securities having an expected aggregate offering price of at least One Million
Dollars ($1,000,000), the Company will, subject to the limitations of Section
9(a)(ii), use its best efforts to effect such registration under the 1933 Act
(including, without limitation, appropriate qualification under applicable blue
sky or other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                                    (A) In any particular jurisdiction in which
the Company would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the Company
is already subject to service in such jurisdiction and except as may be required
by the 1933 Act;

                                    (B) Prior to the six (6) months after the
closing date of the Company's first registered public offering of its stock
(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);

                                    (C) During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good faith and using all reasonable efforts to cause such initial
registration statement to become effective;

                                       6
<PAGE>   103

                                    (D) After the Company has effected one (1)
such registration pursuant to a Holder's demand under this Section 10(a)(i),
which registration has been declared effective; or

                                    (E) If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                  (ii) Underwriting. In the event that a registration pursuant
to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

         (b) Piggy-back Registration Rights.


                  (i) Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).

                                       7
<PAGE>   104

                  (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

         (c) Obligations of the Company. Whenever required under this Section 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                  (i) 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
Holder, keep such registration statement effective for up to one hundred twenty
(120) days.

                  (ii) 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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                  (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                  (iv) Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                  (v) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement with terms
generally satisfactory to the managing

                                       8
<PAGE>   105

underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                  (vi) Notify the Holder, at any time when a prospectus relating
thereto is required to be delivered under the 1933 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 light of the circumstances then
existing. In such instance, Company shall use its best efforts to cure any such
statement or omission so as to render such statement or omission not misleading.

         (d) Furnish Information. In connection with any action pursuant to this
Section 10, the 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 their Registrable Securities. In that connection, the Holder shall be
required to represent to the Company that all such information which is given is
both complete and accurate in all material respects when made.

         (e) Definition of Expenses.

                  (i) "Registration Expenses" shall mean all expenses incurred
by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                  (ii) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of the Registrable Securities in
the registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

         (f) Expenses of Registration. The Company shall bear all Registration
Expenses incurred in connection with (i) any registration, qualification or
compliance pursuant to Section 10(a), and (ii) no more than three (3)
registrations pursuant to Section 10(b). All Selling Expenses shall be borne by
the Holder.

         (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:

                  (i) To the extent permitted by law, the Company will indemnify
and hold harmless the Holder, the officers, directors and partners of the
Holder, any underwriter (as

                                       9
<PAGE>   106

defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                  (ii) To the extent permitted by law, the Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other security holder in such registration statement or any of its partners,
directors or officers or any person who controls such security holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity

                                       10
<PAGE>   107

agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                  (iii) Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                  (iv) In order to provide for just and equitable contribution
to joint liability under the 1933 Act in any case in which either (i) any
indemnified party makes a claim under this Section 10(g) or any controlling
person of such indemnified party makes such a claim but is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent


                                       11
<PAGE>   108

misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the Investor
Rights Agreement and (iii) the Holder shall not make a demand registration which
could result in such registration statement being declared effective prior six
months after the effective date of the Company's initial public offering of
securities pursuant to a registration filed under the 1933 Act or within one
hundred twenty (120) days of the effective date of any demand registration
pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.


                  (i) The Company shall have no obligations pursuant to Section
10 with respect to any request or requests made by the Holder after the date
which is five (5) years following the date of the consummation of the first sale
of securities pursuant to a registration statement filed by the Company under
the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                  (ii) Notwithstanding any contrary provision of this Section
10(i), the Company shall not be required to effect any registrations under the
1933 Act or under any state securities laws on behalf of the Holder if, in the
opinion of counsel to the Company, the offering or transfer by such Holder in
the manner proposed (including, without limitation, the number of shares
proposed to be offered or transferred, the time of sale, and the method of
offering or transfer) is exempt from the registration requirements of the 1933
Act and the securities laws of applicable states and the Company consents to
such transfer, if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares of securities of every
other person subject to the foregoing restriction) until the end of such period.

         12.      Miscellaneous Provisions.

                  (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

                  (b) Replacement. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense will execute and deliver, in lieu of this
Warrant a new Warrant of like tenor.

                  (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

                  (d) Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

                  (e) Notices. All notices from the Company to the holder of
this Warrant shall be in writing and shall be (i) personally delivered, (ii)

7 hereof, the "Shares") at the purchase price per share specified in Section 2
below.

       1.     Definitions. As used in this Warrant, the following terms, unless
the context otherwise requires, have the following meanings:

              (a)    "Common Stock", when used with reference to stock of the
Company, means all shares, now or hereafter authorized, of the class of Common

<PAGE>   112

1933 Act, and the declaration or ordering of the effectiveness of such

              (h)    The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or

for, or in replacement of, such Common Stock.

       2.     Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.40 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

       3.     Exercise Period. This Warrant shall be exercisable by the Holder
for a term beginning on May 28. 1999, (the "Commencement Date") and ending on
May 27, 2004, (the "Expiration Date").

       4.     Method of Exercise.

              (a)    The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                     (i)    the surrender of the Warrant, together with a duly
executed copy of the form of subscription attached hereto as Appendix I, to the
Secretary of the Company at its principal offices; and

                     (ii)   the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

              (b)    In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                           A

Where X= the number of Shares to be issued to the Holder.

Y= the number of Shares purchasable under this Warrant (at the date of such
exercise).

A= the fair market value of one Share (at the date of such exercise).

B= the Warrant Price (as adjusted to the date of such exercise).



                                       2
<PAGE>   113

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common Stock
         quoted in the NASDAQ National Market System or the Over-the-Counter
         market or the closing price quoted on any exchange on which the Common
         Stock is listed, whichever is applicable, as published in the Western
         Edition of The Wall Street Journal for the five (5) trading days prior
         to the date of determination of the fair market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

              (c)    Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

              (c)    In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

       5.     Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

       6.     Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into




                                       3
<PAGE>   114

Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

       7.     Adjustment of Warrant Price and Number of Shares. The number of
and kind of securities purchasable upon exercise of this Warrant and the
purchase price therefor shall be subject to adjustment from time to time as
follows:

              (a)    Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

              (b)    Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

              (c)    Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.

<PAGE>   115

              (d)    Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

              (e)    No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

       8.     Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

       9.     Exercise, Transfer and Exchange Restrictions.

              (a)    This Warrant, and any rights hereunder, may not be assigned
or transferred, except as provided herein and in accordance with and subject to
the provisions of (i) applicable state securities laws, and (ii) the Securities
Act of 1933, as amended, and the rules and regulations promulgated thereunder
(such Act and such rules and regulations being hereinafter collectively referred
to as the "Act"). Any purported transfer or assignment made other than in
accordance with this Section 9 shall be null and void and of no force and
effect.

              (b)    This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable





                                       5
<PAGE>   116


expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

              (c)    Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

       10.    Registration Rights.

              (a)    Requested Registration.

                     (i)    Request for Registration. In case the Company shall
receive from the Holder a written request that the Company file a registration
statement under the 1933 Act with respect to shares of Registrable Securities
having an expected aggregate offering price of at least One Million Dollars
($1,000,000), the Company will, subject to the limitations of Section 9(a)(ii),
use its best efforts to effect such registration under the 1933 Act (including,
without limitation, appropriate qualification under applicable blue sky or other
state securities laws and appropriate compliance with applicable regulations
issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                            (A)    In any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the 1933 Act;

                            (B)    Prior to the six (6) months after the closing
date of the Company's first registered public offering of its stock (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);

                            (C)    During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good faith and using all reasonable efforts to cause such initial
registration statement to become effective;



                                       6
<PAGE>   117

                            (D)    After the Company has effected one (1) such
registration pursuant to a Holder's demand under this Section 10(a)(i), which
registration has been declared effective; or

                            (E)    If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                     (ii)   Underwriting. In the event that a registration
pursuant to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

       The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

              (b)    Piggy-back Registration Rights.

                     (i)    Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).



                                       7
<PAGE>   118

                     (ii)   Underwriting Requirements in Piggy-back
Registration. The right of the Holder to registration pursuant to Section
10(b)(i) shall be conditioned upon the Holder's participation in such
underwriting and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent provided herein. The Holder shall (together with the
Company and any other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected by the Company. Notwithstanding any other
provision of Section 10(b)(i) and this Section 10(b)(ii), if the underwriter
determines that market factors require a limitation of the number of shares to
be underwritten, the underwriter may (subject to the allocation priority set
forth below) exclude some or all Registrable Securities from such registration
and underwriting.

              (c)    Obligations of the Company. Whenever required under this
Section 9 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                     (i)    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 Holder, keep such registration statement effective for up to one hundred
twenty (120) days.

                     (ii)   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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                     (iii)  Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                     (iv)   Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                     (v)    In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement with
terms generally satisfactory to the managing



                                       8
<PAGE>   119

underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                     (vi)   Notify the Holder, at any time when a prospectus
relating thereto is required to be delivered under the 1933 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 light of the
circumstances then existing. In such instance, Company shall use its best
efforts to cure any such statement or omission so as to render such statement or
omission not misleading.

              (d)    Furnish Information. In connection with any action pursuant
to this Section 10, the 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 their Registrable Securities. In that connection, the Holder
shall be required to represent to the Company that all such information which is
given is both complete and accurate in all material respects when made.

              (e)    Definition of Expenses.

                     (i)    "Registration Expenses" shall mean all expenses
incurred by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                     (ii)   "Selling Expenses" shall mean all underwriting
discounts and selling commissions applicable to the sale of the Registrable
Securities in the registration, all stock transfer taxes and all fees and
disbursements of any additional special counsel (other than the special counsel
provided for in Section 10(e)(i) above) retained in connection with each such
registration by the Holder.

              (f)    Expenses of Registration. The Company shall bear all
Registration Expenses incurred in connection with (i) any registration,
qualification or compliance pursuant to Section 10(a), and (ii) no more than
three (3) registrations pursuant to Section 10(b). All Selling Expenses shall be
borne by the Holder.

              (g)    Indemnification. In the event any Registrable Securities
are included in a registration statement under this Section 10:

                     (i)    To the extent permitted by law, the Company will
indemnify and hold harmless the Holder, the officers, directors and partners of
the Holder, any underwriter (as





                                       9
<PAGE>   120



defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                     (ii)   To the extent permitted by law, the Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who have signed the registration statement, each person, if any, who
controls the Company within the meaning of the 1933 Act, any underwriter (within
the meaning of the 1933 Act) for the Company, any person who controls such
underwriter, and any other security holder in such registration statement or any
of its partners, directors or officers or any person who controls such security
holder, against any losses, claims, damages or liabilities (joint or several) to
which any of the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity






                                       10
<PAGE>   121




agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                     (iii)  Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                     (iv)   In order to provide for just and equitable
contribution to joint liability under the 1933 Act in any case in which either
(i) any indemnified party makes a claim under this Section 10(g) or any
controlling person of such indemnified party makes such a claim but is
judicially determined (by entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 10(g) provides for indemnification in
such case, or (ii) contribution under the 1933 Act may be required on the part
of any such person seeking indemnity under the terms of this Section 10(g);
then, and in each such case, the Company and such person will contribute to the
aggregate losses, claims, damages, or liabilities to which they may be subject
(after contribution from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent




                                       11
<PAGE>   122



misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

              (h)    Investor Rights Agreement. The Holder acknowledges and
agrees that (i) the Company and certain investors have entered into an Investor
Rights Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii)
the Holder may include his securities in a demand registration under the
Investor Rights Agreement only to the extent that the inclusion of his
securities will not reduce the amount of securities to be registered for parties
to the Investor Rights Agreement and (iii) the Holder shall not make a demand
registration which could result in such registration statement being declared
effective prior six months after the effective date of the Company's initial
public offering of securities pursuant to a registration filed under the 1933
Act or within one hundred twenty (120) days of the effective date of any demand
registration pursuant to the Investor Rights Agreement.

              (i)    Termination of Registration Rights.

                     (i)    The Company shall have no obligations pursuant to
Section 10 with respect to any request or requests made by the Holder after the
date which is five (5) years following the date of the consummation of the first
sale of securities pursuant to a registration statement filed by the Company
under the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                     (ii)   Notwithstanding any contrary provision of this
Section 10(i), the Company shall not be required to effect any registrations
under the 1933 Act or under any state securities laws on behalf of the Holder
if, in the opinion of counsel to the Company, the offering or transfer by such
Holder in the manner proposed (including, without limitation, the number of
shares proposed to be offered or transferred, the time of sale, and the method
of offering or transfer) is exempt from the registration requirements of the
1933 Act and the securities laws of applicable states and the Company consents
to such transfer, if required.

              11.    "Market Stand-off" Agreement. The Holder agrees, so long as
the Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares

then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be

Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,

Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

                       OF CHAPARRAL NETWORK STORAGE, INC.
                             Void after July 6, 2004

         This certifies that, subject to the terms and conditions set forth

(the "Holder") or its registered assigns is entitled to purchase from Chaparral

nonassessable shares of Common Stock, $0.001 par value, of the Company (as
adjusted pursuant to Section 7 hereof, the "Shares") at the purchase price per
share specified in Section 2 below.

         1. Definitions. As used in this Warrant, the following terms, unless
the context otherwise requires, have the following meanings:

                  (a) "Common Stock", when used with reference to stock of the
Company, means all shares, now or hereafter authorized, of the class of Common
Stock, $0.001 par value, of the Company currently authorized and shares of any
other class into which those shares may hereafter be changed.

                  (b) "Company" means Chaparral Network Storage, Inc. a Delaware

of the Company under this Warrant.

                  (c) "1933 Act" means the Securities Act of 1933, as amended.

                  (d) "1934 Act" means the Securities Exchange Act of 1934, as
amended.

                  (e) "Convertible equity securities" or "equity securities"
shall mean any of the Company's securities.

                  (f) "Holder" means Sentinel Consulting, LLC, a Delaware

                  (g) The terms "register", "registered" and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with


                                       1
<PAGE>   126



the 1933 Act, and the declaration or ordering of the effectiveness of such
registration statement or document by the SEC.

                  (h) The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

         2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.44 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

         3. Exercise Period. This Warrant shall be exercisable by the Holder for
a term beginning on July 7, 1999, (the "Commencement Date") and ending on July
6, 2004, (the "Expiration Date").

         4. Method of Exercise.

                  (a) The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                           (i) the surrender of the Warrant, together with a
duly executed copy of the form of subscription attached hereto as Appendix I, to
the Secretary of the Company at its principal offices; and

                           (ii) the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

                  (b) In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                          A

Where X=the number of Shares to be issued to the Holder.


                                       2
<PAGE>   127




         Y= the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A= the fair market value of one Share (at the date of such exercise).

         B= the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common Stock
         quoted in the NASDAQ National Market System or the Over-the-Counter
         market or the closing price quoted on any exchange on which the Common
         Stock is listed, whichever is applicable, as published in the Western
         Edition of The Wall Street Journal for the five (5) trading days prior
         to the date of determination of the fair market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

                  (c) Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

                  (d) In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into


                                       3
<PAGE>   128


Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the purchase
price therefor shall be subject to adjustment from time to time as follows:

                  (a) Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

                  (b) Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

                  (c) Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.


                                       4
<PAGE>   129


                  (d) Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

                  (e) No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

         8. Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

         9. Exercise, Transfer and Exchange Restrictions.

                  (a) This Warrant, and any rights hereunder, may not be
assigned or transferred, except as provided herein and in accordance with and
subject to the provisions of (i) applicable state securities laws, and (ii) the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (such Act and such rules and regulations being hereinafter
collectively referred to as the "Act"). Any purported transfer or assignment
made other than in accordance with this Section 9 shall be null and void and of
no force and effect.

                  (b) This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable


                                       5
<PAGE>   130


expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

                  (c) Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

         10. Registration Rights.

                  (a) Requested Registration.

                           (i) Request for Registration. In case the Company
shall receive from the Holder a written request that the Company file a
registration statement under the 1933 Act with respect to shares of Registrable
Securities having an expected aggregate offering price of at least One Million
Dollars ($1,000,000), the Company will, subject to the limitations of Section
9(a)(ii), use its best efforts to effect such registration under the 1933 Act
(including, without limitation, appropriate qualification under applicable blue
sky or other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                                    (A) In any particular jurisdiction in which
the Company would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the Company
is already subject to service in such jurisdiction and except as may be required
by the 1933 Act;

                                    (B) Prior to the six (6) months after the
closing date of the Company's first registered public offering of its stock
(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);

                                    (C) During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good faith and using all reasonable efforts to cause such initial
registration statement to become effective;


                                       6
<PAGE>   131


                           (D) After the Company has effected one (1) such
registration pursuant to a Holder's demand under this Section 10(a)(i), which
registration has been declared effective; or

                           (E) If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                  (ii) Underwriting. In the event that a registration pursuant
to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

         (b) Piggy-back Registration Rights.

                  (i) Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).


                                       7
<PAGE>   132


                  (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

         (c) Obligations of the Company. Whenever required under this Section 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                  (i) 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
Holder, keep such registration statement effective for up to one hundred twenty
(120) days.

                  (ii) 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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                  (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                  (iv) Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                  (v) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement with terms
generally satisfactory to the managing


                                       8
<PAGE>   133

underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                  (vi) Notify the Holder, at any time when a prospectus relating
thereto is required to be delivered under the 1933 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 light of the circumstances then
existing. In such instance, Company shall use its best efforts to cure any such
statement or omission so as to render such statement or omission not misleading.

         (d) Furnish Information. In connection with any action pursuant to this
Section 10, the 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 their Registrable Securities. In that connection, the Holder shall be
required to represent to the Company that all such information which is given is
both complete and accurate in all material respects when made.

         (e) Definition of Expenses.

                  (i) "Registration Expenses" shall mean all expenses incurred
by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                  (ii) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of the Registrable Securities in
the registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

         (f) Expenses of Registration. The Company shall bear all Registration
Expenses incurred in connection with (i) any registration, qualification or
compliance pursuant to Section 10(a), and (ii) no more than three (3)
registrations pursuant to Section 10(b). All Selling Expenses shall be borne by
the Holder.

         (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:

                  (i) To the extent permitted by law, the Company will indemnify
and hold harmless the Holder, the officers, directors and partners of the
Holder, any underwriter (as


                                       9
<PAGE>   134


defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                  (ii) To the extent permitted by law, the Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other security holder in such registration statement or any of its partners,
directors or officers or any person who controls such security holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity


                                       10
<PAGE>   135


agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                  (iii) Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                  (iv) In order to provide for just and equitable contribution
to joint liability under the 1933 Act in any case in which either (i) any
indemnified party makes a claim under this Section 10(g) or any controlling
person of such indemnified party makes such a claim but is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent


                                       11
<PAGE>   136


misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the Investor
Rights Agreement and (iii) the Holder shall not make a demand registration which
could result in such registration statement being declared effective prior six
months after the effective date of the Company's initial public offering of
securities pursuant to a registration filed under the 1933 Act or within one
hundred twenty (120) days of the effective date of any demand registration
pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.

                  (i) The Company shall have no obligations pursuant to Section
10 with respect to any request or requests made by the Holder after the date
which is five (5) years following the date of the consummation of the first sale
of securities pursuant to a registration statement filed by the Company under
the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                  (ii) Notwithstanding any contrary provision of this Section
10(i), the Company shall not be required to effect any registrations under the
1933 Act or under any state securities laws on behalf of the Holder if, in the
opinion of counsel to the Company, the offering or transfer by such Holder in
the manner proposed (including, without limitation, the number of shares
proposed to be offered or transferred, the time of sale, and the method of
offering or transfer) is exempt from the registration requirements of the 1933
Act and the securities laws of applicable states and the Company consents to
such transfer, if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares


                                       12
<PAGE>   137


of securities of every other person subject to the foregoing restriction) until
the end of such period.

         12. Miscellaneous Provisions.

                  (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

                  (b) Replacement. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense will execute and deliver, in lieu of this
Warrant a new Warrant of like tenor.

                  (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

                  (d) Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

                  (e) Notices. All notices from the Company to the holder of
this Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized
reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to


                                       13
<PAGE>   138


have been given as provided above, whether by mail or by courier, as applicable,
if transmitted by telecopier, whichever shall first occur.


         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its duly authorized officer.

                        WARRANT TO PURCHASE COMMON STOCK
                       OF CHAPARRAL NETWORK STORAGE, INC.
                            Void after July 19, 2004

         This certifies that, subject to the terms and conditions set forth
herein, for value received, Sentinel Consulting LLC., a Delaware corporation,
(the "Holder") or its registered assigns is entitled to purchase from Chaparral
Network Storage, Inc., a Delaware corporation (the "Company") up to one hundred
ninety thousand (190,000) fully paid and nonassessable shares of Common Stock,
$0.001 par value, of the Company (as adjusted pursuant to Section 7 hereof, the
"Shares") at the purchase price per share specified in Section 2 below.

         1. Definitions. As used in this Warrant, the following terms, unless
the context otherwise requires, have the following meanings:

            (a) "Common Stock", when used with reference to stock of the
Company, means all shares, now or hereafter authorized, of the class of Common
Stock, $0.001 par value, of the Company currently authorized and shares of any
other class into which those shares may hereafter be changed.

            (b) "Company" means Chaparral Network Storage, Inc. a Delaware
corporation and any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

            (c) "1933 Act" means the Securities Act of 1933, as amended.

            (d) "1934 Act" means the Securities Exchange Act of 1934, as
amended.

            (e) "Convertible equity securities" or "equity securities" shall
mean any of the Company's securities.

            (f) "Holder" means Sentinel Consulting, LLC, a Delaware corporation.

            (g) The terms "register", "registered" and "registration" refer to
a registration effected by preparing and filing a registration statement or
similar document in compliance with





                                       1
<PAGE>   140





the 1933 Act, and the declaration or ordering of the effectiveness of such
registration statement or document by the SEC.

            (h) The term "Registrable Securities" means: (i) the Common Stock or
other equity or convertible equity securities of the Company issued or issuable
upon exercise of this Warrant; and (ii) any Common Stock of the Company issued
(or issuable upon the conversion or exercise of any warrant, right or other
security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

         2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.50 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

         3. Exercise Period. This Warrant shall be exercisable by the Holder
for a term beginning on July 20, 1999, (the "Commencement Date") and ending on
July 19, 2004, (the "Expiration Date").

         4. Method of Exercise.

            (a) The Holder may exercise from time to time, in whole or in part
on or before the Expiration Date, the purchase rights evidenced hereby. Such
exercise shall be effected by:

                (i) the surrender of the Warrant, together with a duly executed
copy of the form of subscription attached hereto as Appendix I, to the
Secretary of the Company at its principal offices; and

                (ii) the payment to the Company, in cash or by check payable to
the order of the Company, of an amount equal to the aggregate purchase price
for the number of Shares designated for purchase in the completed subscription
form.

            (b) In lieu of exercising this Warrant pursuant to Section 4(a),
the Holder may elect to receive shares equal to the value of this Warrant (or
any portion thereof remaining unexercised) by surrender of this Warrant at the
principal office of the Company together with the Subscription Form, in which
event the Company shall issue to the Holder a number of Shares computed using
the following formula:

                                  X = Y (A-B)
                                    --------
                                       A

Where X = the number of Shares to be issued to the Holder.



                                       2
<PAGE>   141





         Y = the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A = the fair market value of one Share (at the date of such exercise).

         B = the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common
         Stock quoted in the NASDAQ National Market System or the
         Over-the-Counter market or the closing price quoted on any exchange on
         which the Common Stock is listed, whichever is applicable, as
         published in the Western Edition of The Wall Street Journal for the
         five (5) trading days prior to the date of determination of the fair
         market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of
         the Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and
         the Holder.

            (c) Upon the request of the Company, the Holder shall also deliver
to the Company an instrument, in form and substance reasonably satisfactory to
counsel for the Company, executed by the Holder certifying that the Shares are
being acquired for investment purposes only and not with a view to their resale
or distribution.

            (c) In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto,
as will be sufficient to permit the exercise of this Warrant for the full
number of Shares specified herein and the conversion of the Shares into



                                       3
<PAGE>   142




Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens
and charges with respect to the issuance thereof.

         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the purchase
price therefor shall be subject to adjustment from time to time as follows:

            (a) Stock Splits and Combinations. If the Company shall at any time
subdivide or combine its outstanding shares of the Common Stock, this Warrant
shall, after that subdivision or combination, evidence the right to purchase
the number of shares of Common Stock that would have been issuable as a result
of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at
any time combine the outstanding shares of Common Stock, the Warrant Price then
in effect immediately before that combination shall be proportionately
increased. Any adjustment under this Section 7(a) shall become effective at the
close of business on the date the subdivision or combination becomes effective.

            (b) Reclassification, Exchange and Substitution. If the Common Stock
issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common
Stock which the Holder would have become entitled to purchase but for such
change, a number of shares of such other series or class or classes of stock
equivalent to the number of shares of Common Stock that would have been subject
to purchase by the Holder on exercise of this Warrant immediately before that
change.

            (c) Reorganization, Mergers, Consolidations or Sale of Assets. If at
any time there shall be a capital reorganization of the Company (other than a
combination, reclassification, exchange, or subdivision of shares provided for
elsewhere in this Warrant) or merger or consolidation of the Company with or
into another corporation, or the sale of the Company's properties and assets
as, or substantially as, an entirety to any other person, then, as a part of
such capital reorganization, merger, consolidation or sale, lawful provision
shall be made so that the Holder of this Warrant shall thereafter be entitled
to receive upon exercise of this Warrant, during the period specified in this
Warrant and upon payment of the Warrant Price then in effect, the number of
shares of stock or other securities or property of the Company, or of the
successor corporation resulting from such merger or consolidation, to which a
holder of the Company's Common Stock deliverable upon exercise of this Warrant
would have been entitled in such capital reorganization, merger, consolidation
or sale if this Warrant had been exercised immediately before that capital
reorganization, merger, consolidation or sale.

            (d) Notice of Adjustments. The Company shall give notice of each
adjustment or readjustment of the number of shares of the Common Stock or other
securities issuable upon exercise of this Warrant and the Warrant Price to the
registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

            (e) No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

         8. Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party
in which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder
of this Warrant at least fifteen (15) days written notice of the proposed
effective date and terms of such offering, transaction or agreements, and if
the Warrant has not been exercised at least before the effective date of such
offering, transaction or agreements, then this Warrant and the rights hereunder
shall be automatically terminated.

         9. Exercise, Transfer and Exchange Restrictions.

            (a) This Warrant, and any rights hereunder, may not be assigned or
transferred, except as provided herein and in accordance with and subject to
the provisions of (i) applicable state securities laws, and (ii) the Securities
Act of 1933, as amended, and the rules and regulations promulgated thereunder
(such Act and such rules and regulations being hereinafter collectively
referred to as the "Act"). Any purported transfer or assignment made other than
in accordance with this Section 9 shall be null and void and of no force and
effect.

            (b) This Warrant, and any rights hereunder, may be transferred or
assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable




                                       5
<PAGE>   144




expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

            (c) Any assignment permitted hereunder shall be made by surrender of
this Warrant to the Company at its principal office with an assignment duly
executed and funds sufficient to pay any transfer tax. In such event, the
Company shall, without charge, execute and deliver a new Warrant in the name of
the assignee named in such instrument of assignment and this Warrant shall be
promptly canceled.

         10. Registration Rights.


             (a) Requested Registration.

                 (i) Request for Registration. In case the Company shall
receive from the Holder a written request that the Company file a registration
statement under the 1933 Act with respect to shares of Registrable Securities
having an expected aggregate offering price of at least One Million Dollars
($1,000,000), the Company will, subject to the limitations of Section 9(a)(ii),
use its best efforts to effect such registration under the 1933 Act (including,
without limitation, appropriate qualification under applicable blue sky or
other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements
or regulations) as may be so requested and as would permit or facilitate the
sale and distribution of all or such portion of such Registrable Securities as
are specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                           (A) In any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required
by the 1933 Act;

                           (B) Prior to the six (6) months after the closing
date of the Company's first registered public offering of its stock (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);

                           (C) During the period starting with the date sixty
(60) days prior to the Company's estimated date of filing of, and ending on the
date six (6) months immediately following the closing date of, any initial
registration statement pertaining to securities of the Company (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); provided, however, that the Company is acting in
good faith and using all reasonable efforts to cause such initial registration
statement to become effective;




                                       6
<PAGE>   145





                           (D) After the Company has effected one (1) such
registration pursuant to a Holder's demand under this Section 10(a)(i), which
registration has been declared effective; or

                           (E) If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period
not to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                  (ii) Underwriting. In the event that a registration pursuant
to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the
Holder to registration pursuant to Section 10(a)(i) shall be conditioned upon
such Holder's participation in the underwriting arrangements required by this
Section 10(a)(ii), and the inclusion of the Holder's Registrable Securities in
the underwriting to the extent requested shall be limited to the extent
provided herein.

         The Company shall, together with the Holder, enter into an
underwriting agreement in customary form with a managing underwriter selected
for such underwriting by the Company. Notwithstanding any other provision of
this Section 10(a), if the managing underwriter advises the Holder in writing
that market factors require a limitation of the number of shares to be
underwritten, then the number of shares of Registrable Securities that may be
included in the registration shall be so limited.

         (b) Piggy-back Registration Rights.

             (i) Piggy-back Registration Rights. 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 Holder)
any of its securities under the 1933 Act in connection with the public offering
of such securities solely for cash (other than a registration (i) on Form S-8
or 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 (ii) with respect to an employee benefit plan, or
(iii) solely in connection with a Rule 145 transaction under the 1933 Act), the
Company shall, each such time, promptly give the Holder written notice of such
registration together with a list of the jurisdictions in which the Company
intends to attempt to qualify such securities under applicable state securities
laws. Upon the written request of the Holder given within twenty (20) business
days after delivery of such written notice by the Company, the Company shall,
subject to the provisions of Section 10(b)(ii), use its best efforts to cause
to be registered under the 1933 Act all of the Registrable Securities that the
Holder has requested to be registered. The Company shall be required to effect
not more than three (3) such registrations of Registrable Securities pursuant
to the request of the Holder under this Section 10(b).




                                       7
<PAGE>   146





                  (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below)
exclude some or all Registrable Securities from such registration and
underwriting.

            (c) Obligations of the Company. Whenever required under this Section
9 to effect the registration of any Registrable Securities, the Company shall,
as expeditiously as reasonably possible:

                  (i) 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
Holder, keep such registration statement effective for up to one hundred twenty
(120) days.

                  (ii) 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 1933 Act with respect to the disposition of all
securities covered by such registration statement.

                  (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                  (iv) Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                  (v) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement with terms
generally satisfactory to the managing




                                       8
<PAGE>   147





underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                  (vi) Notify the Holder, at any time when a prospectus
relating thereto is required to be delivered under the 1933 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 light of the
circumstances then existing. In such instance, Company shall use its best
efforts to cure any such statement or omission so as to render such statement
or omission not misleading.

            (d) Furnish Information. In connection with any action pursuant to
this Section 10, the 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 their Registrable Securities. In that connection, the Holder
shall be required to represent to the Company that all such information which
is given is both complete and accurate in all material respects when made.

            (e) Definition of Expenses.

                  (i) "Registration Expenses" shall mean all expenses incurred
by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                  (ii) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of the Registrable Securities in
the registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

            (f) Expenses of Registration. The Company shall bear all
Registration Expenses incurred in connection with (i) any registration,
qualification or compliance pursuant to Section 10(a), and (ii) no more than
three (3) registrations pursuant to Section 10(b). All Selling Expenses shall
be borne by the Holder.

            (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:

                  (i) To the extent permitted by law, the Company will indemnify
and hold harmless the Holder, the officers, directors and partners of the
Holder, any underwriter (as





                                       9
<PAGE>   148





defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the
1934 Act, any state securities law or any rule or regulation promulgated under
the 1933 Act, the 1934 Act or any state securities law; and the Company will
reimburse the Holder, officer, director or partner, underwriter or controlling
person for any legal or other expenses reasonably incurred by them, as
incurred, in connection with investigating or defending any such loss, claim,
damage, liability, or action; provided, however, that the Company's indemnity
contained in this Section 10(g) 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 Company (which consent shall not be
unreasonably withheld), nor shall the Company be liable 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 in writing and expressly stated
for use in connection with such registration by the Holder, or the Holder's
officers, directors or partners, underwriter, or controlling person. The
Company shall not be required to indemnify any person against any liability
arising (i) from any untrue or misleading statement or omission contained in
any preliminary prospectus if such deficiency is corrected in the final
prospectus or (ii) out of the failure of any person to deliver a prospectus as
required by the 1993 Act. The indemnity provided for in this Section 10(g)
shall remain in full force and effect regardless of any investigation made by
or on behalf of such seller, underwriter, participating person or controlling
person and shall survive transfer of such securities by such seller.

         (ii) To the extent permitted by law, the Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers who have
signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other security holder in such registration statement or any of its
partners, directors or officers or any person who controls such security
holder, against any losses, claims, damages or liabilities (joint or several)
to which any of the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in
connection with such registration; and the Holder will reimburse any legal or
other expenses, as incurred, where same are reasonably incurred by any person
intended to be indemnified pursuant to this Section 10(g), in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity



                                      10
<PAGE>   149




agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

         (iii) Promptly after receipt by an indemnified party under this
Section 10(g) 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 10(g),
notify the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

         (iv) In order to provide for just and equitable contribution to joint
liability under the 1933 Act in any case in which either (i) any indemnified
party makes a claim under this Section 10(g) or any controlling person of such
indemnified party makes such a claim but is judicially determined (by entry of
a final judgment or decree by a court of competent jurisdiction and the
expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after
contribution from others) 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; provided, however, that, in any such case, (A) no
such person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent






                                      11
<PAGE>   150






misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall
be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the
Investor Rights Agreement and (iii) the Holder shall not make a demand
registration which could result in such registration statement being declared
effective prior six months after the effective date of the Company's initial
public offering of securities pursuant to a registration filed under the 1933
Act or within one hundred twenty (120) days of the effective date of any demand
registration pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.

             (i) The Company shall have no obligations pursuant to Section 10
with respect to any request or requests made by the Holder after the date which
is five (5) years following the date of the consummation of the first sale of
securities pursuant to a registration statement filed by the Company under the
1933 Act in connection with the initial firm commitment underwritten offering
of its securities to the general public.

             (ii) Notwithstanding any contrary provision of this Section 10(i),
the Company shall not be required to effect any registrations under the 1933
Act or under any state securities laws on behalf of the Holder if, in the
opinion of counsel to the Company, the offering or transfer by such Holder in
the manner proposed (including, without limitation, the number of shares
proposed to be offered or transferred, the time of sale, and the method of
offering or transfer) is exempt from the registration requirements of the 1933
Act and the securities laws of applicable states and the Company consents to
such transfer, if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities,
not to sell, make any short sale of, loan, grant any option for the purchase
of, or otherwise dispose of any Common Stock of the Company (other than those
Common Stock shares included in the registration) without the prior written
consent of the Company or such underwriters, as the case may be, for such
period of time (not to exceed one hundred eighty (180) days) from the closing
date of such registration as may be requested by the underwriters; provided,
however, that such covenants shall apply only if (i) all of the officers and
directors of the Company who own stock of the Company and (ii) each shareholder
owning more than two percent (2%) of the Company's shares also agree to such
restrictions on any shares not being registered in such offering. In order to
enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of the Holder (and the
shares





                                      12
<PAGE>   151




of securities of every other person subject to the foregoing restriction) until
the end of such period.

         12. Miscellaneous Provisions.

             (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

             (b) Replacement. On receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant and,
in the case of loss, theft or destruction, on delivery of any indemnity
agreement or bond reasonably satisfactory in form and amount to the Company or,
in the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense will execute and deliver, in lieu of this Warrant a new
Warrant of like tenor.

             (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any
purpose, nor shall anything in this Warrant be construed to confer on any
Holder of this Warrant, as such, any rights of a shareholder of the Company or
any right to vote, give or withhold consent to any corporate action, to receive
notice of meetings of stockholders (except as set forth in this Warrant), to
receive dividends or subscription rights or otherwise.

             (d) Governing Law. This Warrant shall be governed by and construed
and enforced in accordance with the laws of the State of California applicable
to contracts entered into and wholly to be performed in California by
California residents.

             (e) Notices. All notices from the Company to the holder of this
Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the

                       OF CHAPARRAL NETWORK STORAGE, INC.
                            Void after August 8, 2004

       This certifies that, subject to the terms and conditions set forth

par value, of the Company (as adjusted pursuant to Section 7 hereof, the

       1.     Definitions. As used in this Warrant, the following terms, unless

of the Company under this Warrant.

              (c)    "1933 Act" means the Securities Act of 1933, as amended.

                                       1
<PAGE>   154

              (h)    The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

       2.     Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.50 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

       3.     Exercise Period. This Warrant shall be exercisable by the Holder
for a term beginning on August 9, 1999, (the "Commencement Date") and ending on
August 8, 2004, (the "Expiration Date").

       4.     Method of Exercise.

              (a)    The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                     (i)    the surrender of the Warrant, together with a duly
executed copy of the form of subscription attached hereto as Appendix I, to the
Secretary of the Company at its principal offices; and

                     (ii)   the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

              (b)    In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                           A

Where X = the number of Shares to be issued to the Holder.



                                       2
<PAGE>   155
         Y = the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A = the fair market value of one Share (at the date of such exercise).

         B = the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i)  The average of the closing bid and asked prices of the Common
         Stock quoted in the NASDAQ National Market System or the
         Over-the-Counter market or the closing price quoted on any exchange on
         which the Common Stock is listed, whichever is applicable, as published
         in the Western Edition of The Wall Street Journal for the five (5)
         trading days prior to the date of determination of the fair market
         value; or

         (ii)  If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

              (c)    Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

              (c)    In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

       5.     Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

       6.     Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into




                                       3
<PAGE>   156


Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

       7.     Adjustment of Warrant Price and Number of Shares. The number of
and kind of securities purchasable upon exercise of this Warrant and the
purchase price therefor shall be subject to adjustment from time to time as
follows:

              (a)    Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

              (b)    Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

              (c)    Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.



                                       4


<PAGE>   157
              (d)    Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

              (e)    No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

       8.     Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

       9.     Exercise, Transfer and Exchange Restrictions.

              (a)    This Warrant, and any rights hereunder, may not be assigned
or transferred, except as provided herein and in accordance with and subject to
the provisions of (i) applicable state securities laws, and (ii) the Securities
Act of 1933, as amended, and the rules and regulations promulgated thereunder
(such Act and such rules and regulations being hereinafter collectively referred
to as the "Act"). Any purported transfer or assignment made other than in
accordance with this Section 9 shall be null and void and of no force and
effect.

              (b)    This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable




                                       5
<PAGE>   158

expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

              (c)    Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

       10.    Registration Rights.

              (a)    Requested Registration.

                     (i)    Request for Registration. In case the Company shall
receive from the Holder a written request that the Company file a registration
statement under the 1933 Act with respect to shares of Registrable Securities
having an expected aggregate offering price of at least One Million Dollars
($1,000,000), the Company will, subject to the limitations of Section 9(a)(ii),
use its best efforts to effect such registration under the 1933 Act (including,
without limitation, appropriate qualification under applicable blue sky or other
state securities laws and appropriate compliance with applicable regulations
issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                            (A)    In any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the 1933 Act;

                            (B)    Prior to the six (6) months after the closing
date of the Company's first registered public offering of its stock (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);

                            (C)    During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good faith and using all reasonable efforts to cause such initial
registration statement to become effective;



                                       6
<PAGE>   159

                            (D)    After the Company has effected one (1) such
registration pursuant to a Holder's demand under this Section 10(a)(i), which
registration has been declared effective; or

                            (E)    If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                     (ii)   Underwriting. In the event that a registration
pursuant to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

       The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

              (b)    Piggy-back Registration Rights.

                     (i)    Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).


                                       7
<PAGE>   160

                     (ii)   Underwriting Requirements in Piggy-back
Registration. The right of the Holder to registration pursuant to Section
10(b)(i) shall be conditioned upon the Holder's participation in such
underwriting and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent provided herein. The Holder shall (together with the
Company and any other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected by the Company. Notwithstanding any other
provision of Section 10(b)(i) and this Section 10(b)(ii), if the underwriter
determines that market factors require a limitation of the number of shares to
be underwritten, the underwriter may (subject to the allocation priority set
forth below) exclude some or all Registrable Securities from such registration
and underwriting.

              (c)    Obligations of the Company. Whenever required under this
Section 9 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                     (i)    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 Holder, keep such registration statement effective for up to one hundred
twenty (120) days.

                     (ii)   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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                     (iii)  Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                     (iv)   Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                     (v)    In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement with
terms generally satisfactory to the managing




                                       8
<PAGE>   161


underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                     (vi)   Notify the Holder, at any time when a prospectus
relating thereto is required to be delivered under the 1933 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 light of the
circumstances then existing. In such instance, Company shall use its best
efforts to cure any such statement or omission so as to render such statement or
omission not misleading.

              (d)    Furnish Information. In connection with any action pursuant
to this Section 10, the 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 their Registrable Securities. In that connection, the Holder
shall be required to represent to the Company that all such information which is
given is both complete and accurate in all material respects when made.

              (e)    Definition of Expenses.

                     (i)    "Registration Expenses" shall mean all expenses
incurred by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                     (ii)   "Selling Expenses" shall mean all underwriting
discounts and selling commissions applicable to the sale of the Registrable
Securities in the registration, all stock transfer taxes and all fees and
disbursements of any additional special counsel (other than the special counsel
provided for in Section 10(e)(i) above) retained in connection with each such
registration by the Holder.

              (f)    Expenses of Registration. The Company shall bear all
Registration Expenses incurred in connection with (i) any registration,
qualification or compliance pursuant to Section 10(a), and (ii) no more than
three (3) registrations pursuant to Section 10(b). All Selling Expenses shall be
borne by the Holder.

              (g)    Indemnification. In the event any Registrable Securities
are included in a registration statement under this Section 10:

                     (i)    To the extent permitted by law, the Company will
indemnify and hold harmless the Holder, the officers, directors and partners of
the Holder, any underwriter (as




                                       9
<PAGE>   162



defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                     (ii)   To the extent permitted by law, the Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who have signed the registration statement, each person, if any, who
controls the Company within the meaning of the 1933 Act, any underwriter (within
the meaning of the 1933 Act) for the Company, any person who controls such
underwriter, and any other security holder in such registration statement or any
of its partners, directors or officers or any person who controls such security
holder, against any losses, claims, damages or liabilities (joint or several) to
which any of the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity





                                       10
<PAGE>   163



agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                     (iii)  Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                     (iv)   In order to provide for just and equitable
contribution to joint liability under the 1933 Act in any case in which either
(i) any indemnified party makes a claim under this Section 10(g) or any
controlling person of such indemnified party makes such a claim but is
judicially determined (by entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 10(g) provides for indemnification in
such case, or (ii) contribution under the 1933 Act may be required on the part
of any such person seeking indemnity under the terms of this Section 10(g);
then, and in each such case, the Company and such person will contribute to the
aggregate losses, claims, damages, or liabilities to which they may be subject
(after contribution from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent




                                       11
<PAGE>   164

misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

              (h)    Investor Rights Agreement. The Holder acknowledges and
agrees that (i) the Company and certain investors have entered into an Investor
Rights Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii)
the Holder may include his securities in a demand registration under the
Investor Rights Agreement only to the extent that the inclusion of his
securities will not reduce the amount of securities to be registered for parties
to the Investor Rights Agreement and (iii) the Holder shall not make a demand
registration which could result in such registration statement being declared
effective prior six months after the effective date of the Company's initial
public offering of securities pursuant to a registration filed under the 1933
Act or within one hundred twenty (120) days of the effective date of any demand
registration pursuant to the Investor Rights Agreement.

              (i)    Termination of Registration Rights.

                     (i)    The Company shall have no obligations pursuant to
Section 10 with respect to any request or requests made by the Holder after the
date which is five (5) years following the date of the consummation of the first
sale of securities pursuant to a registration statement filed by the Company
under the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                     (ii)   Notwithstanding any contrary provision of this
Section 10(i), the Company shall not be required to effect any registrations
under the 1933 Act or under any state securities laws on behalf of the Holder
if, in the opinion of counsel to the Company, the offering or transfer by such
Holder in the manner proposed (including, without limitation, the number of
shares proposed to be offered or transferred, the time of sale, and the method
of offering or transfer) is exempt from the registration requirements of the
1933 Act and the securities laws of applicable states and the Company consents
to such transfer, if required.

       11.    "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares





                                       12
<PAGE>   165
of securities of every other person subject to the foregoing restriction) until
the end of such period.

       12.    Miscellaneous Provisions.

              (a)    Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

              (b)    Replacement. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, on delivery of any indemnity
agreement or bond reasonably satisfactory in form and amount to the Company or,
in the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense will execute and deliver, in lieu of this Warrant a new
Warrant of like tenor.

              (c)    No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

              (d)    Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

              (e)    Notices. All notices from the Company to the holder of this
Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized
reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to



                                       13
<PAGE>   166

have been given as provided above, whether by mail or by courier, as applicable,
if transmitted by telecopier, whichever shall first occur.


       IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by
its duly authorized officer.

                       OF CHAPARRAL NETWORK STORAGE, INC.
                           Void after August 11, 2004

         This certifies that, subject to the terms and conditions set forth
herein, for value received, Sentinel Consulting LLC., a Delaware corporation,
(the "Holder") or its registered assigns is entitled to purchase from Chaparral
Network Storage, Inc., a Delaware corporation (the "Company") up to thirty

of Common Stock, $0.001 par value, of the Company (as adjusted pursuant to
Section 7 hereof, the "Shares") at the purchase price per share specified in
Section 2 below.

         1. Definitions. As used in this Warrant, the following terms, unless
the context otherwise requires, have the following meanings:

                  (a) "Common Stock", when used with reference to stock of the
Company, means all shares, now or hereafter authorized, of the class of Common
Stock, $0.001 par value, of the Company currently authorized and shares of any
other class into which those shares may hereafter be changed.

                  (b) "Company" means Chaparral Network Storage, Inc. a Delaware

of the Company under this Warrant.

                  (c) "1933 Act" means the Securities Act of 1933, as amended.

                  (d) "1934 Act" means the Securities Exchange Act of 1934, as

                  (g) The terms "register", "registered" and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with the 1933 Act, and the
declaration or ordering of the effectiveness of such registration statement or
document by the SEC.



                                       1
<PAGE>   168
                  (h) The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

         2. Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $0.65 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

         3. Exercise Period. This Warrant shall be exercisable by the Holder for
a term beginning on August 12, 1999, (the "Commencement Date") and ending on
August 11, 2004, (the "Expiration Date").

         4. Method of Exercise.

                  (a) The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                           (i) the surrender of the Warrant, together with a
duly executed copy of the form of subscription attached hereto as Appendix I, to
the Secretary of the Company at its principal offices; and

                           (ii) the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

                  (b) In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                          A

Where X = the number of Shares to be issued to the Holder.



                                       2
<PAGE>   169
         Y = the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A = the fair market value of one Share (at the date of such exercise).

         B = the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i) The average of the closing bid and asked prices of the Common Stock
         quoted in the NASDAQ National Market System or the Over-the-Counter
         market or the closing price quoted on any exchange on which the Common
         Stock is listed, whichever is applicable, as published in the Western
         Edition of The Wall Street Journal for the five (5) trading days prior
         to the date of determination of the fair market value; or

         (ii) If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

                  (c) Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

                  (d) In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

         5. Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

         6. Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into



                                       3
<PAGE>   170
Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

         7. Adjustment of Warrant Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the purchase
price therefor shall be subject to adjustment from time to time as follows:

                  (a) Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

                  (b) Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

                  (c) Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.



                                       4
<PAGE>   171
                  (d) Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

                  (e) No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

         8. Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

         9. Exercise, Transfer and Exchange Restrictions.

                  (a) This Warrant, and any rights hereunder, may not be
assigned or transferred, except as provided herein and in accordance with and
subject to the provisions of (i) applicable state securities laws, and (ii) the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (such Act and such rules and regulations being hereinafter
collectively referred to as the "Act"). Any purported transfer or assignment
made other than in accordance with this Section 9 shall be null and void and of
no force and effect.

                  (b) This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable



                                       5
<PAGE>   172
expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

                  (c) Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

         10. Registration Rights.

                  (a) Requested Registration.

                           (i) Request for Registration. In case the Company
shall receive from the Holder a written request that the Company file a
registration statement under the 1933 Act with respect to shares of Registrable
Securities having an expected aggregate offering price of at least One Million
Dollars ($1,000,000), the Company will, subject to the limitations of Section
9(a)(ii), use its best efforts to effect such registration under the 1933 Act
(including, without limitation, appropriate qualification under applicable blue
sky or other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                                    (A) In any particular jurisdiction in which
the Company would be required to execute a general consent to service of process
in effecting such registration, qualification or compliance unless the Company
is already subject to service in such jurisdiction and except as may be required
by the 1933 Act;

                                    (B) Prior to the six (6) months after the
closing date of the Company's first registered public offering of its stock
(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);

                                    (C) During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good faith and using all reasonable efforts to cause such initial
registration statement to become effective;



                                       6
<PAGE>   173
                                    (D) After the Company has effected one (1)
such registration pursuant to a Holder's demand under this Section 10(a)(i),
which registration has been declared effective; or

                                    (E) If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                  (ii) Underwriting. In the event that a registration pursuant
to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

         The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

         (b) Piggy-back Registration Rights.

                  (i) Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).



                                       7
<PAGE>   174
                  (ii) Underwriting Requirements in Piggy-back Registration. The
right of the Holder to registration pursuant to Section 10(b)(i) shall be
conditioned upon the Holder's participation in such underwriting and the
inclusion of the Holder's Registrable Securities in the underwriting to the
extent provided herein. The Holder shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected by the Company. Notwithstanding any other provision of
Section 10(b)(i) and this Section 10(b)(ii), if the underwriter determines that
market factors require a limitation of the number of shares to be underwritten,
the underwriter may (subject to the allocation priority set forth below) exclude
some or all Registrable Securities from such registration and underwriting.

         (c) Obligations of the Company. Whenever required under this Section 9
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

                  (i) 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
Holder, keep such registration statement effective for up to one hundred twenty
(120) days.

                  (ii) 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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                  (iii) Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                  (iv) Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                  (v) In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement with terms
generally satisfactory to the managing



                                       8
<PAGE>   175
underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                  (vi) Notify the Holder, at any time when a prospectus relating
thereto is required to be delivered under the 1933 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 light of the circumstances then
existing. In such instance, Company shall use its best efforts to cure any such
statement or omission so as to render such statement or omission not misleading.

         (d) Furnish Information. In connection with any action pursuant to this
Section 10, the 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 their Registrable Securities. In that connection, the Holder shall be
required to represent to the Company that all such information which is given is
both complete and accurate in all material respects when made.

         (e) Definition of Expenses.

                  (i) "Registration Expenses" shall mean all expenses incurred
by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                  (ii) "Selling Expenses" shall mean all underwriting discounts
and selling commissions applicable to the sale of the Registrable Securities in
the registration, all stock transfer taxes and all fees and disbursements of any
additional special counsel (other than the special counsel provided for in
Section 10(e)(i) above) retained in connection with each such registration by
the Holder.

         (f) Expenses of Registration. The Company shall bear all Registration
Expenses incurred in connection with (i) any registration, qualification or
compliance pursuant to Section 10(a), and (ii) no more than three (3)
registrations pursuant to Section 10(b). All Selling Expenses shall be borne by
the Holder.

         (g) Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 10:

                  (i) To the extent permitted by law, the Company will indemnify
and hold harmless the Holder, the officers, directors and partners of the
Holder, any underwriter (as



                                       9
<PAGE>   176
defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                  (ii) To the extent permitted by law, the Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other security holder in such registration statement or any of its partners,
directors or officers or any person who controls such security holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity



                                       10
<PAGE>   177
agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                  (iii) Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                  (iv) In order to provide for just and equitable contribution
to joint liability under the 1933 Act in any case in which either (i) any
indemnified party makes a claim under this Section 10(g) or any controlling
person of such indemnified party makes such a claim but is judicially determined
(by entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case notwithstanding the fact
that this Section 10(g) provides for indemnification in such case, or (ii)
contribution under the 1933 Act may be required on the part of any such person
seeking indemnity under the terms of this Section 10(g); then, and in each such
case, the Company and such person will contribute to the aggregate losses,
claims, damages, or liabilities to which they may be subject (after contribution
from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent



                                       11
<PAGE>   178
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

         (h) Investor Rights Agreement. The Holder acknowledges and agrees that
(i) the Company and certain investors have entered into an Investor Rights
Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii) the
Holder may include his securities in a demand registration under the Investor
Rights Agreement only to the extent that the inclusion of his securities will
not reduce the amount of securities to be registered for parties to the Investor
Rights Agreement and (iii) the Holder shall not make a demand registration which
could result in such registration statement being declared effective prior six
months after the effective date of the Company's initial public offering of
securities pursuant to a registration filed under the 1933 Act or within one
hundred twenty (120) days of the effective date of any demand registration
pursuant to the Investor Rights Agreement.

         (i) Termination of Registration Rights.

                  (i) The Company shall have no obligations pursuant to Section
10 with respect to any request or requests made by the Holder after the date
which is five (5) years following the date of the consummation of the first sale
of securities pursuant to a registration statement filed by the Company under
the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                  (ii) Notwithstanding any contrary provision of this Section
10(i), the Company shall not be required to effect any registrations under the
1933 Act or under any state securities laws on behalf of the Holder if, in the
opinion of counsel to the Company, the offering or transfer by such Holder in
the manner proposed (including, without limitation, the number of shares
proposed to be offered or transferred, the time of sale, and the method of
offering or transfer) is exempt from the registration requirements of the 1933
Act and the securities laws of applicable states and the Company consents to
such transfer, if required.

         11. "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares



                                       12
<PAGE>   179
of securities of every other person subject to the foregoing restriction) until
the end of such period.

         12. Miscellaneous Provisions.

                  (a) Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

                  (b) Replacement. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company at its expense will execute and deliver, in lieu of this
Warrant a new Warrant of like tenor.

                  (c) No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

                  (d) Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

                  (e) Notices. All notices from the Company to the holder of
this Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized
reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to



                                       13
<PAGE>   180
have been given as provided above, whether by mail or by courier, as applicable,
if transmitted by telecopier, whichever shall first occur.

                           Void after November 4, 2004

       This certifies that, subject to the terms and conditions set forth

                                       1
<PAGE>   182
              (h)    The term "Registrable Securities" means: (i) the Common
Stock or other equity or convertible equity securities of the Company issued or
issuable upon exercise of this Warrant; and (ii) any Common Stock of the Company
issued (or issuable upon the conversion or exercise of any warrant, right or
other security which is issued) by way of a stock split, stock dividend,
recapitalization, merger or other distribution with respect to, or in exchange
for, or in replacement of, such Common Stock.

       2.     Warrant Price. The purchase price to be paid upon exercise of this
Warrant is U.S. $3.00 per share of Common Stock. Such price shall be subject to
adjustment pursuant to Section 7 hereof (such price, as adjusted from time to
time, is herein referred to as the "Warrant Price").

       3.     Exercise Period. This Warrant shall be exercisable by the Holder
for a term beginning on November 4, 1999, (the "Commencement Date") and ending
on November 4, 2004, (the "Expiration Date").

       4.     Method of Exercise.

              (a)    The Holder may exercise from time to time, in whole or in
part on or before the Expiration Date, the purchase rights evidenced hereby.
Such exercise shall be effected by:

                     (i)    the surrender of the Warrant, together with a duly
executed copy of the form of subscription attached hereto as Appendix I, to the
Secretary of the Company at its principal offices; and

                     (ii)   the payment to the Company, in cash or by check
payable to the order of the Company, of an amount equal to the aggregate
purchase price for the number of Shares designated for purchase in the completed
subscription form.

              (b)    In lieu of exercising this Warrant pursuant to Section
4(a), the Holder may elect to receive shares equal to the value of this Warrant
(or any portion thereof remaining unexercised) by surrender of this Warrant at
the principal office of the Company together with the Subscription Form, in
which event the Company shall issue to the Holder a number of Shares computed
using the following formula:

                  X  =  Y (A-B)
                        -------
                           A

Where X = the number of Shares to be issued to the Holder.


                                       2
<PAGE>   183
         Y = the number of Shares purchasable under this Warrant (at the date of
         such exercise).

         A = the fair market value of one Share (at the date of such exercise).

         B = the Warrant Price (as adjusted to the date of such exercise).

For purposes of this subsection fair market value of one Share shall mean:

         (i)  The average of the closing bid and asked prices of the Common
         Stock quoted in the NASDAQ National Market System or the
         Over-the-Counter market or the closing price quoted on any exchange on
         which the Common Stock is listed, whichever is applicable, as published
         in the Western Edition of The Wall Street Journal for the five (5)
         trading days prior to the date of determination of the fair market
         value; or

         (ii)  If the Common Stock is not publicly traded, the per share fair
         market value of the Common Stock shall be determined in good faith by
         the Company's Board of Directors. If the Holder disagrees with the
         determination by the Board of Directors of the fair market value of the
         Common Stock then such fair market value shall be determined by an
         independent appraiser selected jointly by the Company and the Holder.
         The cost of such appraisal shall be paid equally by the Company and the
         Holder.

              (c)    Upon the request of the Company, the Holder shall also
deliver to the Company an instrument, in form and substance reasonably
satisfactory to counsel for the Company, executed by the Holder certifying that
the Shares are being acquired for investment purposes only and not with a view
to their resale or distribution.

              (c)    In the event of a partial exercise of this Warrant, a new
Warrant shall be issued to the Holder representing the balance of the Shares
purchasable under this Warrant, such new Warrant to be issued within ten (10)
days after delivery of the subscription notice.

       5.     Certificate for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued in the name of the Holder as soon as practicable
following receipt of the completed subscription form and payment for the Shares
being purchased and in any event within ten (10) days thereafter. The Company
shall not be required to issue any fractional shares upon the exercise of the
Holder's purchaser rights under this Warrant. In lieu of any fractional shares,
the Company shall pay cash equal to such fraction multiplied by the per share
market price of the Common Stock as of the date of exercise.

       6.     Reservation of Shares. The Company covenants that it will at all
times keep available such number of authorized shares of its Series A Preferred
Stock and Common Stock, free from all preemptive rights with respect thereto, as
will be sufficient to permit the exercise of this Warrant for the full number of
Shares specified herein and the conversion of the Shares into



                                       3
<PAGE>   184


Common Stock. The Company further covenants that such Shares, when issued
pursuant to the exercise of this Warrant, will, upon issuance, be duly and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof.

       7.     Adjustment of Warrant Price and Number of Shares. The number of
and kind of securities purchasable upon exercise of this Warrant and the
purchase price therefor shall be subject to adjustment from time to time as
follows:

              (a)    Stock Splits and Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of the Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to
purchase the number of shares of Common Stock that would have been issuable as a
result of that change with respect to the shares of the Common Stock which were
purchasable under this Warrant immediately before that subdivision or
combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Warrant Price then in
effect immediately before that combination shall be proportionately increased.
Any adjustment under this Section 7(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective.

              (b)    Reclassification, Exchange and Substitution. If the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other series or class or classes of stock,
whether by capital reorganization, reclassification, or otherwise (other than a
subdivision or combination of shares provided for above), the Holder of this
Warrant shall, on its exercise, be entitled to purchase, in lieu of Common Stock
which the Holder would have become entitled to purchase but for such change, a
number of shares of such other series or class or classes of stock equivalent to
the number of shares of Common Stock that would have been subject to purchase by
the Holder on exercise of this Warrant immediately before that change.

              (c)    Reorganization, Mergers, Consolidations or Sale of Assets.
If at any time there shall be a capital reorganization of the Company (other
than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere in this Warrant) or merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as a part of such capital reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Holder of this Warrant shall
thereafter be entitled to receive upon exercise of this Warrant, during the
period specified in this Warrant and upon payment of the Warrant Price then in
effect, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation, to which a holder of the Company's Common Stock deliverable upon
exercise of this Warrant would have been entitled in such capital
reorganization, merger, consolidation or sale if this Warrant had been exercised
immediately before that capital reorganization, merger, consolidation or sale.

                                       4
<PAGE>   185

              (d)    Notice of Adjustments. The Company shall give notice of
each adjustment or readjustment of the number of shares of the Common Stock or
other securities issuable upon exercise of this Warrant and the Warrant Price to
the registered Holder of this Warrant at that Holder's address as shown on the
Company's books within twenty (20) days after the occurrence of the event
resulting in such adjustment.

              (e)    No Change Necessary. The form of this Warrant need not be
changed because of any adjustment in the number of shares of the Common Stock
purchasable upon its exercise. A Warrant issued after any adjustment upon any
partial exercise or in replacement may continue to express the same number of
shares of Common Stock (appropriately reduced in the case of partial exercise)
as are stated on the face of this Warrant as initially issued, and that number
of shares shall be considered to have been so changed at the close of business
on the date of adjustment.

       8.     Automatic Termination. In the event of (i) the closing of the
Company's registration statement on a Form S-1 (or any other form equivalent
thereto) pursuant to which any class of the Company's securities is sold to the
public in a public offering registered under the Securities Act of 1933, as
amended; or (ii) the proposed sale of all or substantially all the capital
stock, or substantially all the assets, of the Company in a merger, business
combination, or other form of business transaction with or into a third party in
which the Company's stockholders do not own at least a majority of the
outstanding voting securities of the surviving corporation or business entity
after such transaction (based solely on such Company stockholders' holdings of
the Company prior to the transaction), then the Company shall give the Holder of
this Warrant at least fifteen (15) days written notice of the proposed effective
date and terms of such offering, transaction or agreements, and if the Warrant
has not been exercised at least before the effective date of such offering,
transaction or agreements, then this Warrant and the rights hereunder shall be
automatically terminated.

       9.     Exercise, Transfer and Exchange Restrictions.

              (a)    This Warrant, and any rights hereunder, may not be assigned
or transferred, except as provided herein and in accordance with and subject to
the provisions of (i) applicable state securities laws, and (ii) the Securities
Act of 1933, as amended, and the rules and regulations promulgated thereunder
(such Act and such rules and regulations being hereinafter collectively referred
to as the "Act"). Any purported transfer or assignment made other than in
accordance with this Section 9 shall be null and void and of no force and
effect.

              (b)    This Warrant, and any rights hereunder, may be transferred
or assigned only with the prior written consent of the Company, which shall be
granted only upon receipt by the Company of an opinion of counsel satisfactory
to the Company that (i) the transferee is a person to whom this Warrant may be
legally transferred without registration under the Act, and (ii) such transfer
will not violate any applicable law or governmental rule or regulation,
including, without limitation, any applicable federal or state securities law.
Prior to the transfer or assignment, the assignor or transferor shall reimburse
the Company for its reasonable



                                       5
<PAGE>   186

expenses, including transfer taxes and attorneys' fees, incurred in connection
with the transfer or assignment.

              (c)    Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with an
assignment duly executed and funds sufficient to pay any transfer tax. In such
event, the Company shall, without charge, execute and deliver a new Warrant in
the name of the assignee named in such instrument of assignment and this Warrant
shall be promptly canceled.

       10.    Registration Rights.

              (a)    Requested Registration.

                     (i)    Request for Registration. In case the Company shall
receive from the Holder a written request that the Company file a registration
statement under the 1933 Act with respect to shares of Registrable Securities
having an expected aggregate offering price of at least One Million Dollars
($1,000,000), the Company will, subject to the limitations of Section 9(a)(ii),
use its best efforts to effect such registration under the 1933 Act (including,
without limitation, appropriate qualification under applicable blue sky or other
state securities laws and appropriate compliance with applicable regulations
issued under the 1933 Act and any other governmental requirements or
regulations) as may be so requested and as would permit or facilitate the sale
and distribution of all or such portion of such Registrable Securities as are
specified in such request; provided, however, that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 10(a)(i):

                            (A)    In any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the 1933 Act;

                            (B)    Prior to the six (6) months after the closing
date of the Company's first registered public offering of its stock (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);

                            (C)    During the period starting with the date
sixty (60) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following the closing date of, any
initial registration statement pertaining to securities of the Company (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); provided, however, that the Company is
acting in good faith and using all reasonable efforts to cause such initial
registration statement to become effective;


                                       6
<PAGE>   187

                            (D)    After the Company has effected one (1) such
registration pursuant to a Holder's demand under this Section 10(a)(i), which
registration has been declared effective; or

                            (E)    If the Company shall furnish to Holder a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company and its shareholders for a registration statement to be filed at
such time, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 10(a)(i) shall be deferred for a period not
to exceed one hundred twenty (120) days from the date of receipt of written
request from the Holder; provided, however, that the Company may not make such
certification more than once every twelve (12) months.

                     (ii)   Underwriting. In the event that a registration
pursuant to Section 10(a)(i) is for a registered public offering involving an
underwriting, the Company shall so advise the Holder and the right of the Holder
to registration pursuant to Section 10(a)(i) shall be conditioned upon such
Holder's participation in the underwriting arrangements required by this Section
10(a)(ii), and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

       The Company shall, together with the Holder, enter into an underwriting
agreement in customary form with a managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
10(a), if the managing underwriter advises the Holder in writing that market
factors require a limitation of the number of shares to be underwritten, then
the number of shares of Registrable Securities that may be included in the
registration shall be so limited.

              (b)    Piggy-back Registration Rights.

                     (i)    Piggy-back Registration Rights. 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
Holder) any of its securities under the 1933 Act in connection with the public
offering of such securities solely for cash (other than a registration (i) on
Form S-8 or 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 (ii) with respect to an employee benefit
plan, or (iii) solely in connection with a Rule 145 transaction under the 1933
Act), the Company shall, each such time, promptly give the Holder written notice
of such registration together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of the Holder given within twenty (20)
business days after delivery of such written notice by the Company, the Company
shall, subject to the provisions of Section 10(b)(ii), use its best efforts to
cause to be registered under the 1933 Act all of the Registrable Securities that
the Holder has requested to be registered. The Company shall be required to
effect not more than three (3) such registrations of Registrable Securities
pursuant to the request of the Holder under this Section 10(b).


                                       7
<PAGE>   188

                     (ii)   Underwriting Requirements in Piggy-back
Registration. The right of the Holder to registration pursuant to Section
10(b)(i) shall be conditioned upon the Holder's participation in such
underwriting and the inclusion of the Holder's Registrable Securities in the
underwriting to the extent provided herein. The Holder shall (together with the
Company and any other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected by the Company. Notwithstanding any other
provision of Section 10(b)(i) and this Section 10(b)(ii), if the underwriter
determines that market factors require a limitation of the number of shares to
be underwritten, the underwriter may (subject to the allocation priority set
forth below) exclude some or all Registrable Securities from such registration
and underwriting.

              (c)    Obligations of the Company. Whenever required under this
Section 9 to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                     (i)    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 Holder, keep such registration statement effective for up to one hundred
twenty (120) days.

                     (ii)   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 1933 Act with respect to the disposition of all securities
covered by such registration statement.

                     (iii)  Furnish to the Holder such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the 1933 Act, and such other documents as they may reasonably
request in order to facilitate the disposition of Registrable Securities owned
by it.

                     (iv)   Use its best efforts to register and qualify the
securities covered by such registration statement under the securities laws of
such jurisdictions as shall be reasonably appropriate for the distribution of
the securities covered by the registration statement; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such jurisdiction, and further provided that (anything in this
Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall
require that expenses incurred in connection with the qualification of the
securities in that jurisdiction be borne by selling shareholders, then such
expenses shall be payable by the Holder, to the extent required by such
jurisdiction if the Holder does elect to withdraw from the registration after
notice of such requirement.

                     (v)    In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement with
terms generally satisfactory to the managing




                                       8
<PAGE>   189

underwriter of such offering. The Holder shall also enter into and perform its
obligations under such an agreement.

                     (vi)   Notify the Holder, at any time when a prospectus
relating thereto is required to be delivered under the 1933 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 light of the
circumstances then existing. In such instance, Company shall use its best
efforts to cure any such statement or omission so as to render such statement or
omission not misleading.

              (d)    Furnish Information. In connection with any action pursuant
to this Section 10, the 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 their Registrable Securities. In that connection, the Holder
shall be required to represent to the Company that all such information which is
given is both complete and accurate in all material respects when made.

              (e)    Definition of Expenses.

                     (i)    "Registration Expenses" shall mean all expenses
incurred by the Company in complying with Section 10 hereof, including, without
limitation, all registration, filing and qualification fees, underwriters'
expense allowances, printing expenses, fees and disbursements of counsel for the
Company, reasonable fees and expenses of one special counsel retained in
connection with each such registration by the Holder, blue sky fees and
disbursements, and the expense of any special audits incident to or required by
any registration pursuant to Section 10(a) (but excluding the compensation of
regular employees of the Company which shall be paid in any event by the
Company).

                     (ii)   "Selling Expenses" shall mean all underwriting
discounts and selling commissions applicable to the sale of the Registrable
Securities in the registration, all stock transfer taxes and all fees and
disbursements of any additional special counsel (other than the special counsel
provided for in Section 10(e)(i) above) retained in connection with each such
registration by the Holder.

              (f)    Expenses of Registration. The Company shall bear all
Registration Expenses incurred in connection with (i) any registration,
qualification or compliance pursuant to Section 10(a), and (ii) no more than
three (3) registrations pursuant to Section 10(b). All Selling Expenses shall be
borne by the Holder.

              (g)    Indemnification. In the event any Registrable Securities
are included in a registration statement under this Section 10:

                     (i)    To the extent permitted by law, the Company will
indemnify and hold harmless the Holder, the officers, directors and partners of
the Holder, any underwriter (as



                                       9
<PAGE>   190

defined in the 1933 Act) for the Holder and each person, if any, who controls
the Holder or underwriter within the meaning of the 1933 Act or the 1934 Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the 1933 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 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 1933 Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the 1933 Act,
the 1934 Act or any state securities law; and the Company will reimburse the
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them, as incurred, in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the Company's indemnity contained in this
Section 10(g) 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 Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable 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 in writing and expressly stated for use in connection with
such registration by the Holder, or the Holder's officers, directors or
partners, underwriter, or controlling person. The Company shall not be required
to indemnify any person against any liability arising (i) from any untrue or
misleading statement or omission contained in any preliminary prospectus if such
deficiency is corrected in the final prospectus or (ii) out of the failure of
any person to deliver a prospectus as required by the 1993 Act. The indemnity
provided for in this Section 10(g) shall remain in full force and effect
regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

                     (ii)   To the extent permitted by law, the Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers who have signed the registration statement, each person, if any, who
controls the Company within the meaning of the 1933 Act, any underwriter (within
the meaning of the 1933 Act) for the Company, any person who controls such
underwriter, and any other security holder in such registration statement or any
of its partners, directors or officers or any person who controls such security
holder, against any losses, claims, damages or liabilities (joint or several) to
which any of the foregoing persons may become subject, under the 1933 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 the Holder expressly stated in a writing for use in connection with
such registration; and the Holder will reimburse any legal or other expenses, as
incurred, where same are reasonably incurred by any person intended to be
indemnified pursuant to this Section 10(g), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity




                                       10
<PAGE>   191

agreement contained in this Section 10(g) 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. Notwithstanding the foregoing, the liability of
each Holder under this Section 10(g) shall be limited to an amount equal to the
public offering price of the shares sold by the Holder.

                     (iii)  Promptly after receipt by an indemnified party under
this Section 10(g) 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 10(g), notify
the indemnifying party in writing 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; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonable fees and expenses
to be paid by the indemnifying party if the indemnified party reasonably
determines that 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 notify an
indemnifying party within a reasonable time of the commencement of any such
action, to the extent prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 10(g), but the omission so to notify the indemnifying party will
not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 10(g).

                     (iv)   In order to provide for just and equitable
contribution to joint liability under the 1933 Act in any case in which either
(i) any indemnified party makes a claim under this Section 10(g) or any
controlling person of such indemnified party makes such a claim but is
judicially determined (by entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that this Section 10(g) provides for indemnification in
such case, or (ii) contribution under the 1933 Act may be required on the part
of any such person seeking indemnity under the terms of this Section 10(g);
then, and in each such case, the Company and such person will contribute to the
aggregate losses, claims, damages, or liabilities to which they may be subject
(after contribution from others) 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; provided, however, that, in any such case, (A) no such
person shall be required to contribute any amount in excess of the public
offering price of all such Registrable Securities sold by it pursuant to such
registration statement; and (B) no person or entity guilty of fraudulent





                                       11
<PAGE>   192


misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be
entitled to contribution from any person or entity who was not guilty of such
fraudulent misrepresentation.

              (h)    Investor Rights Agreement. The Holder acknowledges and
agrees that (i) the Company and certain investors have entered into an Investor
Rights Agreement dated November, 1998 (the "Investor Rights Agreement"), (ii)
the Holder may include his securities in a demand registration under the
Investor Rights Agreement only to the extent that the inclusion of his
securities will not reduce the amount of securities to be registered for parties
to the Investor Rights Agreement and (iii) the Holder shall not make a demand
registration which could result in such registration statement being declared
effective prior six months after the effective date of the Company's initial
public offering of securities pursuant to a registration filed under the 1933
Act or within one hundred twenty (120) days of the effective date of any demand
registration pursuant to the Investor Rights Agreement.

              (i)    Termination of Registration Rights.

                     (i)    The Company shall have no obligations pursuant to
Section 10 with respect to any request or requests made by the Holder after the
date which is five (5) years following the date of the consummation of the first
sale of securities pursuant to a registration statement filed by the Company
under the 1933 Act in connection with the initial firm commitment underwritten
offering of its securities to the general public.

                     (ii)   Notwithstanding any contrary provision of this
Section 10(i), the Company shall not be required to effect any registrations
under the 1933 Act or under any state securities laws on behalf of the Holder
if, in the opinion of counsel to the Company, the offering or transfer by such
Holder in the manner proposed (including, without limitation, the number of
shares proposed to be offered or transferred, the time of sale, and the method
of offering or transfer) is exempt from the registration requirements of the
1933 Act and the securities laws of applicable states and the Company consents
to such transfer, if required.

       11.    "Market Stand-off" Agreement. The Holder agrees, so long as the
Holder holds at least one percent (1%) of the Company's outstanding voting
equity securities, in connection with the Company's initial underwritten public
offering of the Company's securities that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed one hundred eighty (180) days) from the closing date of such
registration as may be requested by the underwriters; provided, however, that
such covenants shall apply only if (i) all of the officers and directors of the
Company who own stock of the Company and (ii) each shareholder owning more than
two percent (2%) of the Company's shares also agree to such restrictions on any
shares not being registered in such offering. In order to enforce the foregoing
covenant, the Company may impose stop-transfer instructions with respect to the
Registrable Securities of the Holder (and the shares



                                       12
<PAGE>   193

of securities of every other person subject to the foregoing restriction) until
the end of such period.

       12.    Miscellaneous Provisions.

              (a)    Listing. If any shares of the Common Stock required to be
reserved for issuance upon the exercise of this Warrant require registration
with or approval of any governmental authority under any Federal or state law
(other than the Securities Act, as then in effect, or any similar Federal law
then in effect), or listing on any domestic securities exchange, before such
shares may be issued upon such exercise, the Company shall, at its expense and
as expeditiously as possible, use its best efforts to cause such shares to be
duly registered or approved or listed on the relevant domestic securities
exchange, as the case may be.

              (b)    Replacement. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, on delivery of any indemnity
agreement or bond reasonably satisfactory in form and amount to the Company or,
in the case of mutilation, on surrender and cancellation of this Warrant, the
Company at its expense will execute and deliver, in lieu of this Warrant a new
Warrant of like tenor.

              (c)    No Rights as Stockholder. Prior to the exercise of this
Warrant, no Holder of this Warrant, as such, shall be entitled to vote or
receive dividends or be considered a stockholder of the Company for any purpose,
nor shall anything in this Warrant be construed to confer on any Holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of stockholders (except as set forth in this Warrant), to receive
dividends or subscription rights or otherwise.

              (d)    Governing Law. This Warrant shall be governed by and
construed and enforced in accordance with the laws of the State of California
applicable to contracts entered into and wholly to be performed in California by
California residents.

              (e)    Notices. All notices from the Company to the holder of this
Warrant shall be in writing and shall be (i) personally delivered, (ii)
transmitted by mail, postage prepaid, registered or certified, return receipt
requested, or by air mail in the event of mailing for delivery outside of the
country in which mailed, (iii) transmitted by an overnight courier of recognized
reputation or of recognized international reputation in the event of an
international delivery or (iv) transmitted by telecopier (with confirmation by
air mail or courier), to the address furnished to the Company in writing by the
last holder of this Warrant who shall have furnished an address to the Company
in accordance with the provisions of this Section 11(e). Except as otherwise
specified herein, communications shall be deemed to have been duly given on (A)
the date of receipt if delivered personally, (B) the date seven (7) days after
posting if transmitted by mail, (C) the date three (3) days after delivery to
the courier if sent by recognized or internationally recognized courier service,
or (D) the date on which written confirmation would be deemed to




                                       13
<PAGE>   194

have been given as provided above, whether by mail or by courier, as applicable,
if transmitted by telecopier, whichever shall first occur.


       IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by
its duly authorized officer.
