     This summary highlights selected information contained elsewhere in this
prospectus. This summary may not contain all of the information that you should
consider before investing in our common stock. You should carefully read the
entire prospectus including "Risk Factors" and the consolidated financial
statements, before making an investment decision.

                                  OUR BUSINESS

     Mobility Electronics designs, develops and markets connectivity and remote
peripheral component interface, or PCI bus, technology and products for the
computer industry and for a broad range of related embedded processor
applications. The PCI bus is the electrical transmission path linking the
computer's central processing unit with its memory and other peripheral devices,
such as modems, disk drives and local area networks. Our proprietary Split
Bridge(TM) technology consists of a Split Bridge(TM) link, typically two
customized semiconductors, known as application-specific integrated circuits, or
ASIC chips, two connectors and a high-speed, bi-directional cable. Our
technology for the first time allows the primary PCI bus of any computer to be
extended to a remote location with virtually no software or performance
degradation and enables architectural designs of computer systems and
applications that previously were not feasible. Unlike traditional communication
protocols such as Universal Serial Bus, or USB, IEEE 1394, Ethernet and small
computer systems interface, or SCSI, Split Bridge(TM) offers a combination of:

     - high performance, bi-directional gigabit speeds;

     - plug and play ease of use with no unique software requirements;

     - flexible architectural design choices;

     - minimal special size, heat and power requirements; and

     - cost effective pricing.

     Since Split Bridge(TM) technology extends the PCI bus, it can also
accommodate any of the traditional communication protocols in the remote
location as if they are attached to the primary PCI bus. Our Split Bridge(TM)
technology won PC Week's "Best New Technology" award at the fall 1999 COMDEX
trade show, the world's largest information technology event in the computer
industry.

     Today the most prevalent computer architecture, which is incorporated into
virtually all computer systems and in many related embedded processor
applications, uses the PCI bus. However, the PCI bus has a number of key
limitations, most notably a constraint on the number of lines, or circuits, and
loads that can be attached to it. Historically, these limitations have been
mitigated to some extent by attaching a bridge chip to the PCI bus, which in
turn permits a number of additional loads or peripherals to be attached to a
secondary PCI bus, which is also connected to the bridge chip. This procedure
has the major limitation of requiring the secondary PCI bus to be located on the
main PCI bus printed circuit board, or PCB, or attached physically by a
connector which enables extension of the secondary PCI bus to a maximum of
approximately three inches from the PCB. Consequently, the industry today faces
a number of physical and electrical constraints when designing a computer
system, and has been unable to move the secondary PCI bus more than a few inches
from the primary PCI bus. Additionally, traditional communication protocols,
which attempt to address these limitations, have numerous disadvantages since
they generally require a processor, extensive software and other related items.

     Our Split Bridge(TM) technology eliminates many of the physical and
electrical constraints on a primary PCI computer bus and PCB by allowing one or
more Split Bridge(TM) chips to be attached to the primary computer PCI bus, with
the mating Split Bridge(TM) chips installed at a remote location along with the
secondary PCI bus. Split Bridge(TM) technology substantially reduces the
physical space requirements on the primary PCB by eliminating the need for
multiple traditional bridge chip connections and allows the connecting cable to
be small and flexible. Moreover, all of the secondary PCI bus loads and
peripherals do not need to be physically attached to the primary PCI bus;
therefore, Split Bridge(TM) technology enables input/output devices, peripherals
and other technologies to be placed in multiple remote locations. Examples
include providing remote PCI expansion devices for desktop computers and
integrating Split Bridge(TM) technology into keyboard-video-mouse, or KVM,
switches. Split Bridge(TM) technology can also potentially be used to enhance or
expand the existing installed base of PCI-based computers, routers and servers.
Since routers and servers are one of the fastest growing segments of the
computer industry, and because they often already require multiple bridges, the
growth potential for Split Bridge(TM) in the router and server segment could be
quite large.

     Our first major application for Split Bridge(TM) technology is the creation
of a new universal docking product category which allows users of portable
computers to configure a flexible, high performance docking solution that meets
their individual needs, and more importantly, is compatible with essentially all
makes and models of portable computers.

     The portable computer market, which is the fastest growing segment of the
personal computer industry, could benefit from solutions that address the
inherent limitations on PCI bus architecture. Demand in this market has been
fueled by advances in computer technology and the demand for computer mobility.
According to IDC, a leading industry source, the market for portable computing
devices is expected to grow at a compounded annual growth rate of 24.0% from
22.1 million units in 1998 to approximately 64.8 million units in 2003.

     Coupled with this trend toward portability, there has been an increased
demand for computers that are smaller and lighter but have processing
functionality similar to that of the traditional desktop computer. To make these
smaller and lighter computers more convenient to use in the office and home,
port replicators and docking stations have been developed to allow users to
connect to networks, peripheral devices and external power sources, providing
users with all of the features and functionality of a traditional desktop
computer. Port replicators are simple devices that provide users with a cable
management system for peripherals such as full-sized keyboards, power cords,
mice and monitors. Docking stations include basic port replicator features, as
well as more advanced capabilities such as networking, PC card slots, storage
devices and internal power supplies. Attaching and releasing a portable computer
from a port replicator or docking station is typically a one-step procedure that
takes seconds to complete compared to the burdensome task of attaching or
releasing each external device separately. When a portable computer is detached
from a connectivity product, all external devices connected to the connectivity
product stay in place.

     We believe that our universal Split Bridge(TM) docking station product line
will advance the state-of-the-art in docking capability by enabling the user to
configure a docking system which incorporates standard docking station
functionality with the user's preferred peripheral devices and PCI expansion
capability. This potentially creates a basis for a connectivity standard for the
portable computer industry, which would allow the user to replace the desktop
computer with a fully integrated, customizable mobile computing system. Our
universal Split Bridge(TM) docking station is capable of being upgraded due to
its modular design, providing the user with enhanced flexibility, and is
designed to work with most standard notebook computers and PCI based computing
devices, regardless of the manufacturer or model.

     Our universal docking station product line further provides distributors,
retailers and value-added resellers with the ability to carry a limited number
of universal and expandable docking products, as opposed to many individual
docking stations that only work with one computer model. Thus, distributors,
retailers and value-added resellers can offer flexible choices to their
customers and have products readily available when new computer models become
available, while at the same time maintaining a limited SKU count. Finally,
these products offer computer original equipment manufacturers, or OEMs, the
ability to use our standardized docking solution for their portable computer
models.

     In addition to our Split Bridge(TM) technology products, we also design,
develop and market a range of connectivity and power products for portable
computers. Our current major customers include Buy.com, Compaq, CompUSA,
Gateway, Hewlett-Packard, Hitachi, IBM, Ingram Micro, Merisel, Microwarehouse,
Mitsubishi, NEC, Pinacor, Targus, Tech Data and Toshiba.

     We were formed as a limited liability company under the laws of the State
of Delaware in September 1995 and were converted to a Delaware corporation by a
merger effected in August 1996, in which we were the surviving entity. We
changed our name from "Electronics Accessory Specialists International, Inc." to
"Mobility Electronics, Inc." on July 23, 1998. Our principal executive offices

                                  RISK FACTORS

     This offering involves a high degree of risk. You should carefully consider
the risks and uncertainties described below and the other information in this
prospectus before deciding whether to invest in shares of our common stock. Any
of the following risks could cause the trading price of our common stock to
decline.

RISKS RELATED TO OUR BUSINESS

WE HAVE A HISTORY OF LOSSES AND MAY NOT BE PROFITABLE IN THE FUTURE.

     We have experienced significant operating losses since inception and, as of
September 30, 1999, have an accumulated deficit of approximately $43.6 million.
We expect to have a net loss in the fourth quarter of fiscal 1999. We expect to
continue to incur operating losses in fiscal 2000. If we do not achieve
continued revenue growth sufficient to absorb our recent and planned
expenditures, we could experience additional losses in future periods. These
losses or fluctuations in our operating results could cause the market value of
our common stock to decline. As a result of our continued losses and uncertainty
surrounding our ability to meet our anticipated operating and working capital
needs, the independent auditors' report on our 1998 consolidated financial
statements has been modified for a going concern. See note 2 to our consolidated
financial statements.

     We anticipate that in the future we will make significant investments in
our operations, particularly to support technological developments and sales
activities and, that as a result, operating expenses will continue to increase.
We intend to make such investments on an ongoing basis, primarily from cash
generated from operations and, to the extent necessary, funds available from our
lines of credit and this offering, as we develop and introduce new products and
expand into new markets such as international, direct and OEM markets. If net
sales do not increase with capital or other investments, we are likely to
continue to incur net losses and our financial condition could be materially
adversely affected. We have not yet achieved profitability, and there can be no
assurance that we will achieve or sustain profitability on a quarterly or annual
basis.

OUR FUTURE SUCCESS IS UNCERTAIN BECAUSE SPLIT BRIDGE(TM) TECHNOLOGY IS NEW TO
OUR BUSINESS.

     We began developing the Split Bridge(TM) technology during the first
quarter of 1998, and in the first quarter of 1999, we changed our overall
strategy to pursue the application of the Split Bridge(TM) technology as our
primary focus. Prior to changing our business strategy, we developed and
manufactured port replicators and power products. Our new business focus and
strategy may not be successful. In addition, because we have only recently begun
to focus our business on the development and application of the Split Bridge(TM)
technology, we cannot be sure that our business model and future operating
performance will yield the results that we seek. Our operating results for
future periods are subject to all of the risks and uncertainties inherent in the
establishment of new business enterprises. Our future operating results will
depend upon, among other factors:

     - the demand for our products;

     - the level of product and price competition;

     - our success in establishing and expanding our direct and indirect
       distribution channels;

     - our success in attracting and retaining strategic partners, joint
       ventures and licensing opportunities;

     - our success in attracting and retaining motivated and qualified
       personnel;

     - our ability to expand our international and domestic sales;

                                        7
<PAGE>   10

     - our development and marketing of new products;

     - our ability to control costs; and

     - the general health of the portable computer market and general economic
       conditions.

     If we are not successful in addressing such risks, we could be materially
adversely affected.

WE MAY NOT ACHIEVE ANTICIPATED REVENUES IF MARKET ACCEPTANCE OF OUR SPLIT
BRIDGE(TM) TECHNOLOGY IS NOT FORTHCOMING.

     We believe that revenues from universal docking stations will account for
substantially all of our revenues for the foreseeable future. Our future
financial performance will depend on market acceptance of our Split Bridge(TM)
technology, including our universal connectivity station product line. The
market for docking stations is characterized by ongoing technological
developments, frequent new product announcements and introductions, evolving
industry standards and changing customer requirements. As a result, if our Split
Bridge(TM) technology and universal connectivity product line do not achieve
widespread market acceptance, we may not achieve anticipated revenues. Although
PCI is an industry standard, the operating systems used by our customers may not
be compatible with our universal docking product line and, as a result, the
available market for our products may be limited.

     Our future financial performance also depends in large part on the
existence and continued growth of market demand for universal connectivity
stations. There can be no assurance that the market or demand for universal
connectivity stations, if any, will develop and continue to grow. Any failure of
this market to develop or grow or our failure to develop a universal
connectivity station that satisfies market needs or that works with all computer
makes or models could have a material adverse effect on our business, results of
operations and financial condition. In addition, demand for our products is
primarily driven by the underlying market demand for portable computers. Should
the growth in demand for portable computers be inhibited, our business, results
of operations and financial condition could be adversely affected.

OUR OPERATING RESULTS ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS, AND AN
UNANTICIPATED DECLINE IN REVENUES MAY CAUSE OUR STOCK PRICE TO FALL.

     It is likely that in some future quarter or quarters our operating results
will be below the expectations of securities analysts and investors. If a
shortfall in revenues occurs, the market price for our common stock may decline
significantly. The factors that may cause our quarterly operating results to
fall short of expectations include:

     - our ability to develop and market products;

     - the timing of our, and our competitors, new product introductions and
       product enhancements;

     - market acceptance of our products;

     - the size and timing of customer orders;

     - changes in the mix of products sold;

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

     - the mix of domestic and international sales;

     - length of sales cycles, competition and pricing in our industry;

     - reduction in demand for existing products and shortening of product
       lifecycles;
                                        8
<PAGE>   11

     - foreign currency exchange rates;

     - seasonality of sales;

     - product defects and other product quality problems;

     - our ability to attract and retain strategic partners;

     - the degree and rate of growth of the markets in which we compete and the
       accompanying demand for our products;

     - our ability to expand our internal and external sales forces;

     - our ability to attract and retain key personnel;

     - our suppliers' ability to perform under their contracts with us; and

     - general economic conditions.

     Many of these factors are beyond our control. For these reasons, you should
not rely on period-to-period comparisons of our financial results to forecast
our future performance.

WE MAY NOT BE ABLE TO ADEQUATELY MANAGE OUR ANTICIPATED GROWTH, WHICH COULD
IMPAIR OUR EFFICIENCY AND NEGATIVELY IMPACT OUR OPERATIONS.

     We may not be able to manage our growth effectively, which could impair our
efficiency, reduce the quality of our solutions, impair further growth and harm
our business, financial condition and operating results. If we do not
effectively manage this growth, we may not be able to operate efficiently or
maintain the quality of our products. Either outcome could harm our operating
results. In the past, we have experienced rapid growth, and we plan to continue
to expand our operations. This expansion is expensive and places a significant
strain on our personnel and other resources. For example, our universal
connectivity station product line is expected to result in a significant
increase in the number of shipments to and from our Scottsdale, Arizona
facility. To manage our expanded operations effectively, we will need to further
improve our operational, financial and management systems and successfully hire,
train, motivate and manage our employees.

OUR FAILURE TO RESPOND TO RAPID TECHNOLOGICAL CHANGES MAY IMPAIR OUR OPERATING
RESULTS.

     The market for our universal connectivity station product line is new and
emerging, and is characterized by rapid technological advances, changing
customer needs and evolving industry standards. Accordingly, to realize our
expectations regarding our operating results, we depend on our ability to:

     - develop, in a timely manner, new products and services that keep pace
       with developments in technology;

     - meet evolving customer requirements; and

     - enhance our current product and service offerings and deliver those
       products and services through appropriate distribution channels.

     We may not be successful in developing and marketing, on a timely and
cost-effective basis, either enhancements to our Split Bridge(TM) technology
products or new products which respond to technological advances and satisfy
increasingly sophisticated customer needs. If we fail to introduce new products,
our operating results may suffer. In addition, if new industry standards emerge
that we do not anticipate or adapt to, our products could be rendered obsolete
and our business could be materially harmed. Alternatively, any delay in the
development of technology upon which our products are based could result in our

                                        9
<PAGE>   12

inability to introduce new products as planned. For example, certain products
that we are currently developing depend upon the availability of USB 2.0. The
success and marketability of technology developed by others is beyond our
control and our dependence on such sources could harm our business, financial
condition and operating results.

WE DEPEND ON LARGE PURCHASES FROM A FEW SIGNIFICANT CUSTOMERS, AND ANY LOSS,
CANCELLATION OR DELAY IN PURCHASES BY THESE CUSTOMERS COULD CAUSE A SHORTFALL IN
REVENUE.

     We derive a substantial portion of our product sales through a relatively
small number of OEMs and third-party distributors. For the year ended December
31, 1998, OEMs and distributors represented 42.8% and 26.8%, respectively, of
our sales during that period. For the nine months ended September 30, 1999, OEMs
and distributors represented 54.3% and 28.9%, respectively, of our sales during
that period.

     While our financial performance depends on large orders from a few
significant OEMs and third-party distributors, with the exception of Targus, our
contractual relationships are generally non-exclusive and cancelable upon notice
to us. In addition:

     - our distributor agreements generally do not require minimum purchases;

     - our customers can stop purchasing and our distributors can stop
       distributing our products at any time; and

     - our distributor agreements generally are not exclusive and are for one
       year terms, with no obligation of the distributors to renew the
       agreements.

     Because our expenses are based on our revenue forecasts, a substantial
reduction or delay in sales of our products to, or unexpected returns from OEMs
and distributors, or the loss of any significant customer could harm our
business. Although our largest customers may vary from period-to-period, we
anticipate that our operating results for any given period will continue to
depend to a significant extent on large orders from a small number of customers.

     There can be no assurance that our distributors will continue their current
relationships with us or that they will not give higher priority to the sale of
other products, which could include products of our competitors. In addition,
effective distributors must devote significant technical, marketing and sales
resources to an often lengthy sales cycle. There can be no assurance that our
current and future distributors will devote sufficient resources to market our
products effectively or that economic or industry conditions will not adversely
affect such distributors. A reduction in sales efforts or a discontinuance of
distribution of our products by our distributors could lead to reduced sales and
have a material adverse effect on our business, results of operations and
financial condition. In addition, because we sell a significant portion of our
products through distributors, it is difficult for us to monitor end user demand
for our products on a current basis. For example, third-party distributors may
place large initial orders which may not be indicative of long-term end user
demand.

     Our operating results could also be materially adversely affected by
changes in distributors' inventory strategies, which could occur rapidly and, in
many cases, may not be related to end user demand. New products may require
different marketing, sales and distribution strategies than those for our
current products. There can be no assurance that our distributors will choose or
be able to effectively market these new products or to continue to market our
products. A failure of our distributors to successfully market our products
could have a material adverse effect on our business, results of operations and
financial condition.

                                       10
<PAGE>   13

OUR RELIANCE ON SINGLE OR LIMITED SOURCES FOR KEY COMPONENTS MAY INHIBIT OUR
ABILITY TO MEET CUSTOMER DEMAND.

     The principal components of our docking station products are purchased from
outside vendors. We buy components under purchase orders and generally do not
have long-term agreements with our suppliers. Any termination of or significant
disruption in our relationship with our component suppliers may prevent us from
filling customer orders in a timely manner, as we generally do not maintain
large inventories of our components. We purchase a number of the components for
our products from sole or a limited number of suppliers; for example, Philips
Semiconductors is our sole supplier of Split Bridge(TM) technology ASIC chips,
Molex is our sole supplier of certain system connectors for use with our
universal docking products, EFA is the only manufacturer of our USB docking
stations and Solectron is the only company that produces our Split Bridge(TM)
universal docking stations for us. EFA and Solectron are located in the Far
East. We have occasionally experienced and may in the future experience delays
in delivery of such components. Although alternate suppliers are available for
most of the components and services needed to produce our products, the number
of suppliers of some components is limited, and qualifying a replacement
supplier and receiving components from alternate suppliers could take several
months.

     We depend upon our suppliers to deliver components that are free from
defects, competitive in functionality and cost and in compliance with our
specifications and delivery schedules. Disruption in supply, a significant
increase in the cost of one or more components, failure of a supplier to remain
competitive in functionality or price, the failure of a supplier to comply with
any of our procurement needs or the financial failure or bankruptcy of a
supplier could delay or interrupt our ability to manufacture or deliver our
products to customers on a timely basis and could have a material adverse effect
on our business, results of operations and financial condition.

OUR RELIANCE ON THIRD-PARTY MANUFACTURING VENDORS TO MANUFACTURE OUR PRODUCTS
MAY CAUSE A DELAY IN OUR ABILITY TO FILL ORDERS.

     We rely on third-party manufacturers for assembly and subassembly of our
products. Any termination of or significant disruption in our relationship with
the third-party manufacturers of our products may prevent us from filling
customer orders in a timely manner, as we generally do not maintain large
inventories of our products. Additionally, our use of third-party manufacturers
reduces control over product quality and manufacturing yields and costs. We
depend upon our third-party manufacturers to deliver our products that are free
from defects, competitive in functionality and cost and in compliance with our
specifications and delivery schedules. Moreover, although arrangements with such
manufacturers may contain provisions for warranty obligations on the part of
third-party manufacturers, we remain primarily responsible to our customers for
warranty obligations. Disruption in supply, a significant increase in the cost
of the assembly of our products, failure of a third-party manufacturer to remain
competitive in functionality or price, the failure of a third-party manufacturer
to comply with any of our procurement needs or the financial failure or
bankruptcy of a third-party manufacturer could delay or interrupt our ability to
manufacture or deliver our products to customers on a timely basis and could
have a material adverse effect on our business, results of operations and
financial condition.

OUR SUCCESS DEPENDS UPON SALES TO OEMS, WHOSE UNPREDICTABLE DEMANDS AND
REQUIREMENTS MAY SUBJECT US TO POTENTIAL ADVERSE REVENUE FLUCTUATIONS.

     We expect that we will continue to be dependent upon a limited number of
OEMs for a significant portion of our net sales in future periods, although no
OEM is presently obligated either to purchase a specified amount of products or
to provide us with binding forecasts of product purchases for any period. Our
products are typically one of many related products
                                       11
<PAGE>   14

used by portable computer users. Demand for our products is therefore subject to
many risks beyond our control, including, among others:

     - competition faced by our OEM customers in their particular end markets;

     - market acceptance of the products by our OEM customers;

     - technical challenges which may or may not be related to the components
       supplied by us;

     - the technical, sales and marketing and management capabilities of our OEM
       customers; and

     - the financial and other resources of our OEM customers.

     Certain divisions within our OEM customers have developed products intended
to compete with our products. There can be no assurance that we will not lose
sales in the future as a result of such competing products. The reduction, delay
or cancellation of orders from our significant OEM customers, or the
discontinuance of our products by our end users, could have a material adverse
effect on our business, results of operations and financial condition.

WE HAVE IN THE PAST EXPERIENCED RETURNS OF OUR PRODUCTS, AND AS OUR BUSINESS
GROWS WE MAY EXPERIENCE INCREASED RETURNS, WHICH COULD HARM OUR REPUTATION AND
NEGATIVELY IMPACT OUR OPERATING RESULTS.

     In the past, some of our customers have returned our products to us because
they felt that the product did not meet their expectations, specifications and
requirements. It is likely that we will experience some level of returns in the
future and, as our business grows, the amount of returns may increase despite
our efforts to minimize them. Also, returns may adversely affect our
relationship with affected customers and may harm our reputation. This could
cause us to lose potential customers and business in the future. We maintain a
financial reserve for future returns that we believe is adequate given our
historical level of returns. If returns increase, however, our reserve may not
be sufficient and our operating results could be negatively affected.

INTENSE COMPETITION IN THE MARKET FOR CONNECTIVITY PRODUCTS COULD PREVENT US
FROM INCREASING REVENUE AND SUSTAINING PROFITABILITY.

     Although the market for our universal docking products is relatively new
and emerging and we presently have few direct competitors, we expect that the
markets for our products will become increasingly competitive. The market for
computer products in general is intensely competitive, subject to rapid change
and sensitive to new product introductions or enhancements and marketing efforts
by industry participants. We expect to experience significant and increasing
levels of competition in the future. The principal competitive factors affecting
the markets for our product offerings include:

     - corporate and product reputation;

     - innovation with frequent product enhancement;

     - breadth of integrated product line;

     - product design, functionality and features;

     - product quality and performance;

     - ease-of-use;

                                       12
<PAGE>   15

     - support; and

     - price.

     Although we believe that our products compete favorably with respect to
such factors, there can be no assurance that we can maintain our competitive
position against current or potential competitors, especially those with greater
financial, marketing, service, support, technical or other competitive
resources.

     We currently compete primarily with the internal design efforts of OEMs.
These OEMs, as well as a number of our potential non-OEM competitors, have
larger technical staffs, more established and larger marketing and sales
organizations and significantly greater financial resources than we do. We,
however, believe that we have a proprietary position with respect to our Split
Bridge(TM) technology and universal connectivity stations which may pose a
barrier to entry that could keep our competitors from developing similar
products or selling competing products in our markets. There can be, however, no
assurance that such competitors will not be able to respond more quickly to new
or emerging technologies and changes in customer requirements, devote greater
resources to the development, sale and promotion of their products than we do or
develop products that are superior to our products or that achieve greater
market acceptance.

     Our future success will depend, in part, upon our ability to increase sales
in our targeted markets. There can be no assurance that we will be able to
compete successfully with our competitors or that the competitive pressures we
face will not have a material adverse effect on our business, results of
operations and financial condition. Our future success will depend in large part
upon our ability to increase our share of our target market and to sell
additional products and product enhancements to existing customers. Future
competition may result in price reductions, reduced margins or decreased sales
which in turn could have a material adverse effect on our business, results of
operations and financial condition. See "Business -- Competition."

IF WE ARE UNABLE TO HIRE ADDITIONAL QUALIFIED PERSONNEL AS NECESSARY OR IF WE
LOSE KEY PERSONNEL, WE MAY NOT BE ABLE TO SUCCESSFULLY MANAGE OUR BUSINESS OR
ACHIEVE OUR OBJECTIVES.

     We believe our future success will depend in large part upon our ability to
identify, attract and retain highly skilled managerial, engineering, sales and
marketing, finance and operations personnel. Competition for such personnel in
the computer industry is intense, and we compete for such personnel against
numerous companies, including larger, more established companies with
significantly greater financial resources than us. There can be no assurance we
will be successful in identifying, attracting and retaining such personnel, and
the failure to do so could have a material adverse effect on our business,
results of operations and financial condition.

     Our success also depends to a significant degree upon the continued
contributions of our key management, engineering, sales and marketing, finance
and manufacturing personnel, many of whom would be difficult to replace. In
particular, we believe that our future success depends on Charles R. Mollo,
Chief Executive Officer, Jeffrey S. Doss, Executive Vice President, and Richard
W. Winterich, our recently hired Chief Financial Officer. Except for Mr. Doss,
we do not maintain key person life insurance on any of our executive officers.
Except for Messrs. Doss, Mollo and Winterich, we do not have employment
contracts covering any of our senior management. The loss of the services of any
of our key personnel, the inability to identify, attract or retain qualified
personnel in the future or delays in hiring required personnel could make it
difficult for us to manage our business and meet key objectives, such as timely
product introductions.

                                       13

IF OUR PRODUCTS CONTAIN UNDETECTED SOFTWARE OR HARDWARE ERRORS, WE COULD INCUR
SIGNIFICANT UNEXPECTED EXPENSES AND LOST SALES AND BE SUBJECT TO PRODUCT
LIABILITY CLAIMS.

     Our products are complex and may contain undetected errors or performance
problems, particularly during new and enhanced product launches. Despite product
testing prior to introduction, our products have in the past, on occasion,
contained errors that were discovered after commercial introduction. Errors or
performance problems may also be discovered in the future. Any future defects
discovered after shipment of our products could result in loss of sales, delays
in market acceptance or product returns and warranty costs, which could have a
material adverse effect on our business, results of operations and financial
condition. We attempt to make adequate allowance in our new product release
schedule for testing of product performance. Because of the complexity of our
products, however, our release of new products may be postponed should test
results indicate the need for redesign and retesting, or should we elect to add
product enhancements in response to customer feedback. In addition, third-party
products, upon which our products are dependent, may contain defects which could
reduce or undermine the performance of our products.

     In addition, although our sales agreements with our customers typically
contain provisions designed to limit our exposure to potential product liability
claims, there can be no assurance that such limitations of liability would be
enforceable or would otherwise protect us from liability for damages to a
customer resulting from a defect in one of our products. Although we maintain
liability insurance covering certain damages arising from implementation and use
of our products, there can be no assurance that such insurance would cover or be
sufficient to cover any such claims sought against us. Any product liability or
other claims against us, if successful and of sufficient magnitude, could have a
material adverse effect on our business, results of operations and financial
condition.

IF WE FAIL TO PROTECT OUR INTELLECTUAL PROPERTY, OUR BUSINESS AND ABILITY TO
COMPETE COULD SUFFER.

     Our success and ability to compete are dependent upon our internally
developed technology and know-how. We rely primarily on a combination of
copyright and trademark laws, trade secrets, nondisclosure agreements and
technical measures to protect our proprietary rights. We have two patents issued
and five U.S. patent applications pending. There can be no assurance that
patents pending or future patent applications will be issued. We typically enter
into confidentiality, noncompete or invention assignment agreements with our key
employees, distributors, customers and potential customers, and limit access to,
and distribution of, our product design documentation and other proprietary
information. Additionally, we believe that, due to the rapid pace of innovation
within the computer industry, factors such as:

     - technological and creative skill of personnel;

     - knowledge and experience of management;

     - name recognition;

     - maintenance and support of products;

     - the ability to develop, enhance, market and acquire products and
       services; and

     - the establishment of strategic relationships in the industry

also represent important protections for our technology. There can be no
assurance that our confidentiality agreements, confidentiality procedures,
noncompetition agreements or other factors will be adequate to deter
misappropriation or independent third-party development of

                                       14
<PAGE>   17

our technology or to prevent an unauthorized third party from obtaining or using
information that we regard as proprietary. See "Business -- Proprietary Rights."

WE MAY BE SUBJECT TO INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS THAT ARE COSTLY
TO DEFEND AND COULD LIMIT OUR ABILITY TO USE CERTAIN TECHNOLOGIES IN THE FUTURE.

     The laws of some foreign countries do not protect or enforce proprietary
rights to the same extent as do the laws of the United States. There can be no
assurance that our competitors will not independently develop technology similar
to existing proprietary rights of others. We expect that computer products will
increasingly be subject to infringement claims as the number of products and
competitors in our industry segment grows and the functionality of products in
different industry segments overlaps. There can be no assurance that third
parties will not assert infringement claims against us in the future or, if
infringement claims are asserted, that such claims will be resolved in our
favor. Any infringement claims resolved against us could have a material adverse
effect upon our business, results of operations and financial condition. Any
such claims, with or without merit, could be time-consuming, result in costly
litigation, cause product shipment delays or require us to enter into royalty or
licensing agreements. Such royalty or licensing agreements, if required, may not
be available on terms favorable to us, if at all, which could have a material
adverse effect on our business, results of operations and financial condition.
In addition, litigation may be necessary in the future to protect our trade
secrets or other intellectual property rights, or to determine the validity and
scope of the proprietary rights of others. Such litigation could result in
substantial costs and diversion of resources and could have a material adverse
effect on our business, results of operations and financial condition. See
"Business -- Proprietary Rights."

OUR ABILITY TO INCREASE INTERNATIONAL SALES AND MANAGE OUR INTERNATIONAL
OPERATIONS IS SUBJECT TO A NUMBER OF RISKS BEYOND OUR CONTROL.

     Our success will depend, in part, on additional expansion of our sales in
foreign markets. We have established a relationship with a representative agency
that has exclusive rights to sell our products in Europe. We intend to expand
into other foreign markets. Our failure to expand international sales in a
timely and cost-effective manner could have a material adverse effect on our
business, results of operations and financial condition. In addition, there can
be no assurance we will be able to maintain or increase international market
demand for our products. Our international business involves a number of risks,
including:

     - the impact of possible recessionary environments in foreign economies;

     - political and economic instability;

     - exchange rate fluctuations;

     - longer receivable collection periods and greater difficulty in accounts
       receivable collection from distributors and customers;

     - difficulty in managing distributors or sales representatives;

     - increased sales and marketing expense;

     - difficulty in staffing foreign operations;

     - unexpected changes in regulatory requirements;

     - reduced or limited protection for intellectual property rights;

     - export restrictions and availability of export licenses;

     - tariffs and other trade barriers;

                                       15
<PAGE>   18

     - seasonal reduction in business activities;

     - complex foreign laws and treaties including employment laws; and

     - potentially adverse tax consequences.

     Our international sales are priced in both U.S. dollars and in foreign
currency, each of which presents certain risks and uncertainties. Currency
exchange fluctuations could have a material adverse effect on our sales
denominated in U.S. currency as a decrease in the value of foreign currencies
relative to the U.S. dollar could make our pricing more expensive than, or
non-competitive with, products priced in local currencies. Additionally, due to
the number of foreign currencies involved in our international sales and the
volatility of foreign currency exchange rates, we cannot predict the effect of
exchange rate fluctuations with respect to such sales on future operating
results. We have not engaged in hedging transactions with respect to our net
foreign currency exposure. To the extent we implement hedging activities in the
future with respect to foreign currency transactions, there can be no assurance
that we will be successful in such hedging activities. Any of these factors
could have a material adverse effect on our business, operating results or
financial condition.

     Moreover, certain of our customer purchase agreements are governed by
foreign laws, which may differ significantly from U.S. laws. Therefore, we may
be limited in our ability to enforce our rights under such agreements and to
collect amounts owed to us should any customer refuse to pay such amounts. In
addition, we are subject to the Foreign Corrupt Practices Act which may place us
at a competitive disadvantage with respect to foreign companies that are not
subject to that act.

     In January 1999, the new "Euro" currency was introduced in European
countries that are part of the European Monetary Union, or EMU. During 2002, all
EMU countries are expected to completely replace their national currencies with
the Euro. Because a significant amount of uncertainty exists as to the effect
the Euro will have on the marketplace and because all of the final rules and
regulations have not yet been defined and finalized by the European Commission
regarding the Euro currency, we cannot determine the effect this will have on
our business.

WE MAY NEED ADDITIONAL CAPITAL TO FUND OUR FUTURE OPERATIONS WHICH MAY NOT BE
AVAILABLE TO US ON FAVORABLE TERMS WHEN REQUIRED OR AT ALL.

     We have expended and will continue to expend substantial funds to continue
the research and development and marketing efforts for our current and future
products. Our ability to execute our growth strategy depends to a significant
degree on our ability to obtain substantial additional debt and equity capital.
We believe that our existing working capital together with the proceeds from
this offering and cash available from credit facilities and future operations
will enable us to meet our working capital requirements for at least the next 12
months. However, if cash from future operations is insufficient, or if cash is
used for acquisitions or other currently unanticipated uses, we could be
required to raise substantial additional capital. The precise amount and timing
of our funding needs cannot be determined at this time, and will depend upon a
number of factors, including:

     - the market demand for our products;

     - the progress of our product development efforts;

     - the success of programs we are seeking to implement to improve our
       inventory management; and

     - our management of our cash and accounts payable.

                                       16
<PAGE>   19

     There can be no assurance that funds required by us in the future will be
available on terms satisfactory to us, if at all. If additional funds are raised
through the issuance of equity or convertible debt securities, the percentage
ownership of the existing stockholders will be reduced, such existing
stockholders may experience additional dilution and such securities may have
rights, preferences or privileges senior to those of the holders of our common
stock. Additionally, any debt financing that may be available to us may include
restrictive covenants that would be applicable to us. The inability to obtain
needed funding on satisfactory terms may require us:

     - to reduce planned capital expenditures;

     - to reduce planned levels of advertising and promotion;

     - to scale back our manufacturing or other operations; or

     - to enter into financing arrangements on terms which we would not
       otherwise accept,

and this could have a material adverse effect on our business, results of
operations and financial condition.

WE MAY ENGAGE IN FUTURE ACQUISITIONS THAT COULD RESULT IN THE DILUTION OF OUR
STOCKHOLDERS, CAUSE US TO INCUR SUBSTANTIAL EXPENSES AND HARM OUR BUSINESS IF WE
CANNOT SUCCESSFULLY INTEGRATE THE ACQUIRED BUSINESS, PRODUCTS, TECHNOLOGIES OR
PERSONNEL.

     As part of our business strategy, we may review acquisition prospects that
would complement our existing business or enhance our technological
capabilities. Future acquisitions by us could result in large and immediate
write-offs, the incurrence of debt and contingent liabilities or amortization
expenses related to goodwill and other intangible assets, any of which could
negatively affect our results of operations. Furthermore, acquisitions involve
numerous risks and uncertainties, including:

     - difficulties in assimilation of the operations, products and personnel of
       the acquired companies;

     - the ability to effectively manage geographically remote units;

     - the diversion of management's attention from other business concerns;

     - the potential loss of key employees of acquired companies;

     - risks of entering markets in which we have limited or no direct
       experience;

     - customer dissatisfaction;

     - performance problems with an acquired company;

     - dilutive issuances of equity securities;

     - reduction of existing cash balances; and

     - other effects on us that could have a material adverse effect on our
       business, results of operations and financial condition.

     Although we do not currently have any agreements or plans with respect to
any material acquisitions, we may make acquisitions of complementary businesses,
products or technologies in the future. We may not be able to successfully
integrate any businesses, products, technologies or personnel that might be
acquired in the future, and our failure to do so could harm our business.

THE FAILURE OF OUR PRODUCTS AND COMPUTER SYSTEMS TO BE YEAR 2000 COMPLIANT COULD
HURT OUR BUSINESS.

     Our business could suffer if our products and the computer systems we use,
as well as the computer systems used by our customers, users and vendors, do not
correctly process date-sensitive information in the year 2000 and beyond. We
believe that our products and business systems accurately process year 2000 date
information, but there may be parts of our products and business systems and
aspects of the year 2000 issue, including the potential cost of addressing the
year 2000 issue, that we have failed to consider or have not yet encountered.
There can be no assurance that the ultimate cost to identify and implement
solutions to all year 2000 issues will not be material to us.

RISKS RELATED TO THE OFFERING

OUR EXECUTIVE OFFICERS AND DIRECTORS WILL CONTINUE TO HAVE SUBSTANTIAL CONTROL
OVER OUR BUSINESS AFTER THE OFFERING WHICH COULD DELAY OR PREVENT A MERGER OR
OTHER CHANGE IN CONTROL OF US.

     Upon completion of this offering, our principal stockholders, executive
officers, directors and affiliated individuals and entities together will
beneficially own approximately   % of the outstanding shares of common stock (
  % if the underwriters' over-allotment option is exercised in full). As a
result, these stockholders, acting together, may be able to influence
significantly and possibly control most matters requiring approval by our
stockholders, including approvals of:

     - amendments to our certificate of incorporation;

     - mergers;

     - sale of all or substantially all of our assets;

     - going private transactions; and

     - other fundamental transactions.

     In addition, our certificate of incorporation does not provide for
cumulative voting with respect to the election of directors. Consequently, the
present directors and executive officers, together with our principal
stockholders, may be able to control the election of the members of the board of
directors. Such a concentration of ownership could have an adverse effect on the
price of the common stock, and may have the effect of delaying or preventing a
change in control, including transactions in which stockholders might otherwise
receive a premium for their shares over then current market prices.

SOME PROVISIONS OF OUR CHARTER DOCUMENTS MAY HAVE ANTI-TAKEOVER EFFECTS THAT
COULD DISCOURAGE A CHANGE IN CONTROL AND REDUCE THE MARKET PRICE OF OUR COMMON
STOCK.

     Some provisions of our certificate of incorporation and bylaws could make
it more difficult for a third party to acquire us even if a change of control
would be beneficial to our stockholders. These provisions include:

     - authorizing the issuance of preferred stock without stockholder approval;

     - prohibiting cumulative voting in the election of directors; and

     - limiting the persons who may call special meetings of stockholders.

See "Description of Capital Stock -- Delaware Anti-Takeover Law and Certain
Charter and Bylaw Provisions" for more information regarding anti-takeover
matters.

                                       18
<PAGE>   21

AS OUR COMMON STOCK HAS NOT BEEN PUBLICLY TRADED, OUR STOCK PRICE MAY BE
EXTREMELY VOLATILE AND YOU MAY NOT BE ABLE TO RESELL YOUR SHARES AT OR ABOVE THE
OFFERING PRICE.

     Prior to this offering, there has been no public market for our common
stock. The initial public offering price has been determined through
negotiations between the underwriters and us. You may not be able to resell your
shares at or above the initial public offering price.

     Equity markets, particularly the market for technology companies, have
recently experienced significant price and volume fluctuations that are
unrelated to the operating performance of individual companies. These broad
market fluctuations may cause the market price of our common stock to decline.
In addition, the market price of our common stock is likely to be highly
volatile. In the past, securities class action litigation has often been
instituted against companies following periods of volatility in the market price
of their securities. This litigation could result in substantial costs and a
diversion of management's attention and resources.

     Significant fluctuations in the market price of our common stock could be
caused by a number of factors, including:

     - actual or anticipated fluctuations in our operating results;

     - changes in expectations as to our future financial performance;

     - changes in financial estimates of securities analysts;

     - changes in market valuations of other technology companies;

     - announcements by us or our competitors of significant technical
       innovations, design wins, contracts, standards or acquisitions; and

     - the operating and stock price performance of other comparable companies.

     Due to these factors, the value of your investment in our common stock
could be reduced. These market fluctuations may cause our stock price to decline
regardless of our performance.

OUR MANAGEMENT WILL HAVE BROAD DISCRETION TO USE THE PROCEEDS OF THIS OFFERING
AND THEIR USES MAY NOT YIELD A FAVORABLE RETURN.

     While we intend to use the net proceeds from this offering principally for
working capital needs and general corporate purposes, including the repayment of
approximately $9.0 million of outstanding debt, product and market development,
acquisitions or investments in complimentary businesses or products and the
right to use complimentary technologies, most of the net proceeds of this
offering have not been allocated for specific uses. Our management will have
broad discretion to spend the proceeds from this offering in ways with which
stockholders may not agree. The failure of our management to use these funds
effectively could result in unfavorable returns. This could have significant
adverse effects on our financial condition and could cause the price of our
common stock to decline. See "Use of Proceeds."

THE PURCHASERS IN THE OFFERING WILL IMMEDIATELY EXPERIENCE SUBSTANTIAL DILUTION
IN NET TANGIBLE BOOK VALUE.

     The initial public offering price is substantially higher than the net
tangible book value per share of the outstanding common stock immediately after
the offering. As a result, purchasers of shares will experience immediate and
substantial dilution of approximately $     in net tangible book value per
share, or approximately   % of the initial public offering price of $     per
share. In contrast, existing stockholders paid an average price of $     per
share.

<PAGE>   22

FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE.

     Upon completion of this offering, we will have      shares of common stock
outstanding. All the shares sold in this offering can be freely traded. The
remaining      shares of common stock outstanding after this offering are
subject to lock-up agreements that prohibit the sale of the shares for 180 days
after the date of this prospectus. Immediately after the 180 day lock-up period,
          of these shares will become available for sale. The remaining shares
of our common stock will become available at various times thereafter upon the
expiration of a one-year holding period. Sales of a substantial number of shares
of common stock in the public market after this offering or after the expiration
of the lock-up and holding periods could cause the market price of our common
stock to decline. See "Shares Eligible for Future Sale" for a discussion of
potential future sales of our common stock.

                           FORWARD-LOOKING STATEMENTS

     This prospectus includes forward-looking statements that involve risks and
uncertainties. These forward-looking statements include statements under the
captions "Prospectus Summary," "Risk Factors," "Use of Proceeds," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business" and elsewhere in this prospectus. You should not rely on these
forward-looking statements which apply only as of the date of this prospectus.
These statements refer to our future plans, objectives, expectations and
intentions. We use words such as "believe," "anticipate," "expect," "will,"
"intend," "estimate" and similar expressions to identify forward-looking
statements. This prospectus also contains forward-looking statements attributed
to third parties relating to their estimates regarding the growth of certain
markets. You should not place undue reliance on these forward-looking
statements, which apply only as of the date of this prospectus. Our actual
results could differ materially from those discussed in these forward-looking
statements. Factors that could contribute to these differences include those
discussed in the preceding pages and elsewhere in this prospectus.

                                USE OF PROCEEDS

     The net proceeds to us from the sale of the      shares being offered by us
at an assumed initial public offering price of $     per share, after deducting
estimated underwriting discounts and commissions and estimated offering
expenses, are estimated to be $     , or $     if the underwriters'
over-allotment option is exercised in full. We expect to use the net proceeds of
this offering for working capital and general corporate purposes, including
repayment of approximately $9.0 million of debt in the aggregate as described
below, increased spending on sales and marketing, research and development and
expansion of our operational and administrative infrastructure. Specific amounts
for these purposes, other than the repayment of debt, have not yet been
determined. In addition, we may use a portion of the net proceeds to acquire or
invest in complementary businesses, technologies, product lines or products.
However, we have no current plans, agreements or commitments with respect to any
such acquisition, and we are not currently engaged in any negotiations with
respect to any such transaction. Pending these uses, we intend to invest the net
proceeds in short-term, interest-bearing, investment grade securities.

     We are using a portion of the proceeds from this offering to repay two
revolving loan agreements and one term loan agreement with Bank of America, N.A.
These agreements with Bank of America all mature on March 31, 2000. Borrowings
under the revolvers bear interest at a floating rate of prime plus 2.5% per
annum. The amounts outstanding under the revolvers at December 31, 1999 were
$2.3 million and $466,000. Borrowings under the term loan bear interest at a
floating rate of prime plus 3.5% per annum. The amount outstanding under the
term loan at December 31, 1999 was $916,667. The term loan amortizes at a rate
of $83,333 per month.

     We have two term loans with Sirrom Capital Corporation, now known as Finova
Capital Corporation, or Finova, each bearing interest at 13.5% per annum and
each maturing on June 23, 2002. At December 31, 1999 the amounts outstanding
under the Finova loans were $1.6 million and $1.75 million.

     We have two debt offerings bearing interest at 13% per annum. At December
31, 1999 the amount outstanding under the offering that will mature on March 5,
2000 was $1.2 million and the amount outstanding under the offering that will
mature on July 31, 2000 was $550,000.

     In connection with the acquisition of Miram International, Inc., we assumed
a promissory note bearing interest at 8% per annum and maturing on July 31,
2000. At December 31, 1999

                                       21
<PAGE>   24

$157,000 was outstanding under this note, which amortizes in equal installments
on January 31, 2000, April 30, 2000 and July 31, 2000.

                                DIVIDEND POLICY

     We have never declared or paid cash dividends on our capital stock. We
currently intend to retain all available funds and any future earnings for use
in the operation of our business and do not anticipate paying any cash dividends
in the foreseeable future. Furthermore, our loan agreements prohibit the payment
of cash dividends.

                                    DILUTION

     If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the pro forma as adjusted net tangible book value per share of
our common stock after this offering. We calculate net tangible book value per
share by dividing the net tangible book value (total assets less intangible
assets and total liabilities) by the number of outstanding shares of common
stock.

     Our pro forma net tangible book value at September 30, 1999, was
approximately $     million, or $     per share, based on      shares of our
common stock outstanding after giving effect to the conversion of all
outstanding shares of our Series C preferred stock into common stock, on a
1-to-1.3763 basis, upon the closing of this offering.

     After giving effect to the sale of the      shares of common stock by us at
the assumed initial public offering price of $     per share (less the
underwriting discounts and commissions and estimated offering expenses payable
by us), our pro forma as adjusted net tangible book value at September 30, 1999,
would be $     million, or $     per share. This represents an immediate
increase in the pro forma as adjusted net tangible book value of $     per share
to existing stockholders and an immediate dilution of $     per share to new
investors, or approximately   % of the initial public offering price of $
per share.

     The following table illustrates this per share dilution:

<TABLE>

</TABLE>

     The following table summarizes, on a pro forma basis as of September 30,
1999, the differences between existing stockholders and new investors with
respect to the number of shares of common stock purchased from us, the total

</TABLE>

     The information in the table is based upon the initial public offering
price of $     per share before deducting underwriting discounts and commissions
and offering expenses payable by us. The information concerning existing
stockholders is based on the number of shares of common stock outstanding on
September 30, 1999 and gives effect to the conversion of all outstanding shares
of Series C preferred stock into common stock, on a 1-to-1.3763 basis, upon
completion of this offering. The information presented with respect to existing
stockholders excludes as of September 30, 1999: (1) 754,252 shares subject to
outstanding options and 1,745,748 shares available for future option grants
under our 1996 Plan; (2) 264,396 shares subject to non-plan options; and (3)
3,165,359 shares subject to warrants to purchase common stock. The issuance of
common stock in connection with the exercise of these options and warrants will
result in further dilution to new investors. See notes 10 and 11 to our
consolidated financial statements for more information regarding our equity
structure.

     In the first quarter of 1998 we began to pursue a technology that would
enable us to create a new universal docking product category which allows
portable computer users to configure a flexible, high performance docking
solution that is compatible with essentially all makes and models of portable
computers. The fundamental technology that we developed has far reaching
applications. In the first quarter of 1999, we changed our overall business
strategy to pursue the application of our Split Bridge(TM) technology as our
primary focus.

     Mobility was founded in May 1995 to develop products for the portable
computer market. Initial sales were generated primarily from reselling
third-party power products. In mid-1996 we began manufacturing and shipping our
first port replicator and monitor stand products to Toshiba. During 1997 we
expanded our product offering to include port replicators for other computer
original equipment manufacturers, or OEMs, to meet the growing end user demand
for such products. Sales grew from $118,000 in 1995, to $5.7 million in 1996, to
$12.7 million in 1997 and $21.1 million in 1998. Net losses increased from
$788,000 in 1995, to $2.1 million in 1996, to $8.8 million in 1997 and $18.0
million in 1998.

     After reviewing our financial performance relative to the mechanical port
replicator product line, we determined that we needed to discontinue this
product line. The then available technology required each port replicator to be
unique to each portable computer. It typically took two months to design a unit
and an additional month to ramp up production and have product available in the
market. Lifecycles of portable computers vary, but they average approximately
nine months. With one-third of the lifecycle consumed in design and production
ramp up, it was difficult to generate sufficient unit volume over the remaining
life of the portable computer to amortize the design and tooling costs. In
addition, once the portable computer was replaced in the market by a new model,
we faced the economic issues associated with the distribution channel's return
of unsold product. This resulted in obsolete inventory, as the unit was model
specific to the discontinued portable computer.

     In December 1998, we booked reserves for inventory obsolescence, product
returns and tooling equipment impairment. An additional inventory reserve was
established in the amount of $4.1 million, unamortized tooling in the amount of
$275,000 was written off and a reserve for product returns was established in
the amount of $200,000.

     The product line abandonment plan called for an immediate stop to
mechanical port replicator development. The engineering staff supporting this
activity was dismantled in the first quarter of 1999. The port replicator
product offering was reduced to the finished goods on hand and the build out of
existing component inventory. The final build was completed in July 1999, and we
have continued to sell out of finished goods inventory throughout the year ended
December 31, 1999.

     The product line abandonment plan assumed a migration from the mechanical
port replicator product offering to a universal line of docking stations, which
are not unique to each portable computer. Universal docking stations are a
natural application for the Split

                                       27
<PAGE>   30

Bridge(TM) technology. These docking stations will represent the first
commercial application of the technology. A line of products was designed around
our leading edge Split Bridge(TM) technology and existing USB technology. The
universal nature of the product line overcomes the issues that made the
mechanical port replicator financially unviable. Specifically, the products are
not model specific to portable computers and therefore provide leverage to the
engineering and tooling cost. In addition, the product is compatible with
virtually all PCI-based computers, which eliminates the inventory obsolescence
issues, as the products will be compatible with new portable computer models
into the foreseeable future.

     We also evaluated our basic business strategy relative to the power
products and monitor stand product lines and determined that a fundamental
change was required. During the first half of 1999, we implemented a
manufacturing strategy that migrated in-house production to contract
manufacturers in Taiwan. This strategy was implemented in September 1999. The
outsourcing of manufacturing allows us to concentrate our efforts on
technological development and application.

     As a result of the two aforementioned actions, we have experienced
significant improvement in gross margins in the third quarter of 1999. The new
universal connectivity product line has been set up to use a contract
manufacturing partner in Malaysia and the cost of net sales is predictable based
upon committed price quotations.

     We sell our products directly to OEMs and the retail channel, as well as
through distributors. We have also established a few select worldwide private
label accounts, most notably IBM, NEC and Targus. A substantial portion of our
sales are concentrated among a number of OEMs, including Compaq, Dell,
Hewlett-Packard, IBM, NEC, Targus and Toshiba. Direct sales to OEMs accounted
for 54.3% of net sales in the nine months ended September 30, 1999. Direct sales
to OEMs have declined as a percentage of sales as we have expanded our channels
of distribution in the United States to include distributors and resellers. We
expect that we will continue to be dependent upon a number of OEMs for a
significant portion of our net sales in future periods, although no OEM is
presently obligated to purchase a specified amount of products.

     A portion of our sales to distributors and resellers is generally under
terms that provide for certain stock balancing return privileges and price
protection. Sales to this channel have increased and are expected to further
increase significantly. Accordingly, we make a provision for estimated sales
returns and other allowances related to those sales. Historical returns, which
have been netted in the sales presented herein, have been approximately 6.0% of
sales. The major distributors are allowed to return up to 15.0% of their prior
quarter's purchases under the stock balancing programs, provided that they place
a new order for equal or greater dollar value of the stock balancing return.
Historically, the returns have been primarily mechanical port replicators that
are associated with portable computers that have been replaced in the market. It
is anticipated that the return activity will diminish significantly due to the
nature of the universal connectivity station and the reduced obsolescence
issues.

     We derive a significant portion of our sales outside the United States,
principally in France, Germany and the United Kingdom, to OEMs, retailers and a
limited number of independent distributors. On October 1, 1999 we sold our
international sales subsidiaries in France, Germany and the United Kingdom for
nominal value to Cameron Wilson, our then current president. Mr. Wilson has
resigned from Mobility to develop these former subsidiaries into an independent
representative agency that will market our products exclusively in Europe.
International sales accounted for approximately 19.0% of our net sales for the
nine months ended September 30, 1999. We expect sales outside the United States
to continue to account for a large portion of our net sales. International sales
are generally denominated in the currency of our foreign customers. A decrease
in the value of foreign currencies relative to the U.S. dollar could result in a
significant decrease in U.S. dollar sales received by us for our

                                       28
<PAGE>   31

international sales. We recognized net foreign exchange gains of approximately
$25,403 in the nine months ended September 30, 1999. We have not engaged in
hedging transactions with respect to our net foreign currency exposure. To the
extent that we implement hedging activities in the future with respect to
foreign currency transactions, there can be no assurance that we will be
successful in such hedging activities.

     Various factors have in the past affected and may continue in the future to
affect our gross profits, including but not limited to, our product mix, lower
volume production and higher fixed costs for newly introduced product platforms
and technologies, market acceptance of newly introduced products and the
position of our products in their respective lifecycles. The initial stages of
our product introductions are generally characterized by lower volume production
which is accompanied by higher costs, especially for specific products which are
initially purchased in small volumes during the development lifecycle.

  Nine Months Ended September 30, 1999 and 1998 (unaudited)

     Net sales. Net sales consist of sales of product net of returns and
allowances. We recognize sales at the time goods are shipped and maintain a
reserve for stock rotation transactions with the distribution channel. Net sales
declined 43.9% to $10.2 million for the nine months ended September 30, 1999
from $18.1 million for the nine months ended September 30, 1998. There were
several factors that contributed to the sales decline. We elected to migrate out
of the mechanical port replicator business. Sales in 1999 were limited to
existing products, as all new mechanical port replicator product development was
terminated in the first quarter of 1999. We also terminated our exclusive
distribution arrangement with Extended Systems in July 1998 and initiated
relationships directly with the distribution channel. The volume sold through
the distribution channel was ramping in the first quarter of 1999 after
relationships were established in the fourth quarter of 1998. In

                                       29

addition, we had changed from in-house manufacturing to contracted
manufacturing. Product availability was negatively impacted during the
implementation of this transition.

     Gross profit. Our cost of sales consists primarily of costs associated with
components, outsourced manufacturing and in-house labor associated with
assembly, testing, packaging, shipping, quality assurance, depreciation of
equipment and indirect manufacturing costs. Cost of sales for the nine months
ended September 30, 1999 decreased 54.3% to $8.8 million from $19.3 million for
the nine months ended September 30, 1998. The decrease in cost of sales was
primarily the result of the volume decrease in net sales. Gross profit (loss)
increased to 13.3% of net sales for the nine months ended September 30, 1999
from (6.4)% of net sales for the nine months ended September 30, 1998. The gross
profit for the period ended September 30, 1998 was adversely affected by
inventory reserve increases to reflect obsolescence issues with the mechanical
port replicator dock product line. Although improved as a percent of net sales,
the gross profit for the period ended September 30, 1999 was adversely affected
by a reduction in sales volume, which caused manufacturing overhead to be
underabsorbed, and the additional initial costs incurred as the shift to
contract manufacturing was implemented.

     General and administrative. General and administrative costs consist of
salaries and other personnel related costs of our finance, human resources, MIS,
corporate development and other administrative personnel, professional fees, bad
debt, depreciation and amortization and related expenses. General and
administrative costs increased 6.2% to $2.9 million for the nine months ended
September 30, 1999 from $2.7 million for the nine months ended September 30,
1998. The cost increase was attributed to increases in our European expenses
which were partially offset by staffing cuts in the United States implemented
due to the decline in sales volume. We expect general and administrative costs
to increase in the future, in particular as we incur higher legal, accounting
and other expenses associated with being a public company.

     Research and development. Research and development expenses generally
consist of salaries and other personnel related costs, facilities, outside
consulting, lab costs and travel related costs of our new product development
group. Research and development expenses were $2.6 million for each of the nine
months ended September 30, 1998 and 1999. Expenses increased significantly in
the product development efforts in connection with Split Bridge(TM) technology
and its application to the universal docking product line. Research and
development expenses associated with mechanical port replicator products were
phased out in the first quarter of the nine month period ended September 30,
1999. We expect engineering costs to increase in the future as we continue to
develop next generation chips aimed to keep us at the leading edge of universal
docking and remote PCI bus applications.

     Marketing and sales. Marketing and sales costs generally consist of
salaries, commissions and other personnel related costs of our sales, marketing
and support personnel, advertising, public relations, promotions, printed media
and travel. Marketing and sales expenses increased 17.1% to $3.7 million for the
nine months ended September 30, 1999 from $3.1 million for the nine months ended
September 30, 1998. The increase in cost was primarily due to the launch costs
and packaging development cost for the universal docking product line. We also
incurred incremental expenses to establish direct relationships with the U.S.
distribution channels. We expect marketing and sales costs to continue to
increase in the future as we continue to launch new product lines and as sales
increase.

     Interest expense, net. Interest expense consists of interest on our bank
revolving lines of credit as well as our subordinated debt and convertible
debentures, partially offset by interest earned on our cash balances and
short-term investments. We also issued convertible bridge loan debt that
included warrants. In connection with the offering of Bridge Promissory Notes in
March and July 1999, we recorded a charge for deferred loan expense of $5.4
million

                                       30
<PAGE>   33

relative to such warrants. Based upon normal amortization or the conversion of
the underlying debt, we expensed $4.7 million related to these and other
warrants for the nine months ended September 30, 1999. The warrants are
amortized over the life of the loan and recorded as interest expense upon
conversion. Interest expense increased by 389.1% to $5.6 million for the nine
months ended September 30, 1999 from $1.2 million for the nine months ended
September 30, 1998. The increase was primarily due to the non-cash expense
associated with amortization of the bridge loan warrants which totaled $4.7
million in the nine months ended September 30, 1999. We expect to pay down
substantially all of our debt with the proceeds of the offering.

     Income taxes. We have incurred losses from inception to date; therefore, no
provision for income taxes was required for the nine months ended September 30,
1999 or 1998.

  Years Ended December 31, 1998 and 1997

     Net sales. Net sales increased 65.3% to $21.1 million for the year ended
December 31, 1998 from $12.7 million for the year ended December 31, 1997. The
increase in net sales for the year ended December 31, 1998 was mainly due to the
expansion of our product offering of mechanical port replicators and docking
stations.

     Gross profit. Cost of sales for the year ended December 31, 1998 increased
83.0% to $23.5 million from $12.9 million for the year ended December 31, 1997.
The increase was due to the overall increase in sales volume and a product mix
shift to mechanical port replicators that had higher component costs and start
up issues. An inventory reserve in the amount of $4.1 million was recorded in
the year ended December 31, 1998, reflective of the excess and obsolete
inventory and the write-off associated with our decision to discontinue the
mechanical port replicator product line. The short lifecycles of the mechanical
port replicators generated a significant obsolescence exposure for components
and finished goods which are returned under the stock balancing contract
provision with the major channel distributors. The gross profit (loss) percent
declined to (11.7)% of net sales for the year ended December 31, 1998 from
(0.9)% of net sales for the year ended December 31, 1997.

     General and administrative. General and administrative expenses increased
133.1% to $4.4 million for the year ended December 31, 1998 from $1.9 million in
the year ended December 31, 1997, which represents 21.1% of net sales in 1998
and 15.0% of net sales in 1997. The cost increase was attributed to staffing and
infrastructure additions to support the higher sales volume and anticipated
launch of the universal connectivity products.

     Research and development. Research and development expenses increased 47.8%
to $4.4 million for the year ended December 31, 1998 from $3.0 million in the
year ended December 31, 1997, which included purchased research and development
of $965,000 and which represents 20.7% of net sales in the year ended 1998 and
23.1% of net sales in the year ended 1997. The increased expense was the result
of increased activity on the Split Bridge(TM) technology program.

     Marketing and sales. Marketing and sales expense increased 95.5% to $5.1
million for the year ended December 31, 1998 from $2.6 million in the year ended
December 31, 1997. In 1998 we canceled our distribution agreements with Extended
Systems, Inc. and developed the internal infrastructure to distribute our
products directly through the established U.S. distribution channels. This was
done to eliminate the second layer of distribution cost that put pressure on
gross profit margins. We also increased sales and marketing expenses in
anticipation of the launch of the universal connectivity station products based
upon the Split Bridge(TM) technology. The delay in the ASIC development resulted
in a twelve month delay in the launch program.

                                       31
<PAGE>   34

     Interest expense. Interest expense increased 142.3% to $1.6 million for the
year ended December 31, 1998 from $676,000 for the year ended December 31, 1997.
The increase was due to increases in the outstanding debt balance and the
amortization of deferred loan costs related to warrants issued in conjunction
with debt.

     Income taxes. We have incurred losses from inception to date; therefore, no
provision for income taxes was required for the years ended December 31, 1998 or
1997.

  Years Ended December 31, 1997 and 1996

     Net sales. Net sales increased 124.8% to $12.7 million for the year ended
December 31, 1997 from $5.7 million for the year ended December 31, 1996. The
increase in net sales for the year ended December 31, 1997 was mainly due to the
introduction of new products in our port replicator product line, as well as
increased sales for our existing products.

     Gross profit. Cost of sales for the year ended December 31, 1997 increased
188.8% to $12.9 million from $4.5 million for the year ended December 31, 1996.
This increase was due to higher costs of sales in 1997 for new product platform
and technology introductions, higher overhead expenses, as well as an
incremental $677,000 increase in the provision for inventory losses, primarily
related to many startup issues, and the impact of one new technology program,
which represented 19.2% of 1997 sales and which provided no margin. The gross
profit (loss) declined to (0.9)% of net sales for the year ended December 31,
1997 from $1.2 million, or 21.5% of net sales for the year ended December 31,
1996.

     General and administrative. General and administrative expenses decreased
3.6% to $1.9 million for the year ended December 31, 1997 from $2.0 million for
the year ended December 31, 1996, which represented 15.0% and 34.9% of net
sales, respectively. The expense decrease was attributable to minor staffing and
infrastructure reductions.

     Research and development. Research and development expenses increased
315.0% to $3.0 million for the year ended December 31, 1997 from $711,000 for
the year ended December 31, 1996, which represented 23.1% and 12.6% of net
sales, respectively. The increase in costs was due largely to a $1.0 million
charge in the third quarter of 1997 due to the write-off of in-process research
and development costs related to the Miram acquisition and the development of
new product offerings, in particular the universal connectivity products.

     Marketing and sales. Marketing and sales expenses increased 390.7% to $2.6
million for the year ended December 31, 1997 from $535,000 for the year ended
December 31, 1996, which represented 20.6% and 9.5% of net sales, respectively.
The increase in costs was largely due to the launch of new products during the
period, as well as the costs of building a sales and product management
organization to supplement our distribution channels in the United States.

     Interest expense. Interest expense increased 503.6% to $676,000 for the
year ended December 31, 1997 from $112,000 for the year ended December 31, 1996.
The increase was due to an increase in the outstanding balance of our debt and
amortization of deferred loan costs related to warrants issued in connection
with certain debt.

     Income taxes. We have incurred losses from inception to date, therefore, no
provision for income taxes was required for the year ended December 31, 1997 or
1996.

LIQUIDITY AND CAPITAL RESOURCES

     Since inception, we have funded our operations primarily through debt and
equity financing, as the cost of our operating activities has exceeded our
sales. Our operating activities used cash of $8.9 million, $12.9 million and
$11.2 million for the years ended

                                       32
<PAGE>   35

December 31, 1997 and 1998 and the nine months ended September 30, 1999,
respectively. All references in this section to dates subsequent to December 31,
1998 are unaudited. The increased cash used in operations was primarily due to
our increased operating losses.

     Our financing activities generated cash of $11.6 million, $14.1 million and
$10.1 million for the years ended 1997 and 1998 and the nine months ended
September 30, 1999, respectively. In March 1999 we issued an aggregate of $3.5
million of 13% Bridge Promissory Notes, which are due and payable in March,
2000, and issued warrants for the purchase of 1,050,000 shares of common stock.
In June 1999 $2.3 million of the Bridge Notes were converted to common stock at
a price of $4.00 per share. In June through August 1999 we issued an additional
aggregate of $3.7 million of 13% Bridge Promissory Notes and issued warrants of
the purchase of 898,400 shares of common stock. $3.2 million of these Bridge
Notes were immediately converted to common stock at a price of $4.00 per share.
The balance are due and payable in July 2000. In November 1998 through January
1999 we sold 827,209 shares of Series C preferred stock for an aggregate of
approximately $5 million in a private placement. In April and May 1998 we sold
1,485,000 shares of common stock for an aggregate of $8.5 million in a private
placement, and in September 1997 we sold 2.5 million shares of common stock for
an aggregate of $10.0 million and issued warrants to purchase an additional
625,000 shares of common stock in a private placement. In late 1996 and early
1997 we issued an aggregate of approximately $2.2 million of 12% convertible
debentures. In December 1998 approximately $2.1 million of the convertible
debentures were converted to common stock at a price of $3.86 per share. We also
issued an aggregate of $3.4 million of 13.5% Secured Promissory Notes to Finova
in June 1997 and March 1998 (the "Finova Notes"), which are due and payable on
June 23, 2002. In connection with the issuance of the Finova Notes, we issued
warrants to Finova which are currently exercisable for an aggregate of 418,124
shares of common stock at an exercise price of $0.01 per share (the "Finova
Warrants"). The unconverted portion of the convertible debentures and the Finova
Notes will be repaid with part of the proceeds of this offering.

     Our investing activities used cash of $805,000, $903,000 and $91,000 for
the years ended 1997 and 1998 and the nine months ended September 30, 1999,
respectively. From inception through September 30, 1999, cash used in investing
activities was primarily used for capital purchases, including tooling and
capital leases.

     Our cash and cash equivalents decreased to $1.3 million at September 30,
1999, compared to $2.4 million at December 31, 1998 and $2.2 million at December
31, 1997. Our net working capital (deficit) at those same dates was $(2.4
million), $(3.2 million) and $1.9 million, respectively. At September 30, 1999
our primary source of liquidity other than our cash and cash equivalents were
our foreign and domestic lines of credit with Bank of America totaling $5.0
million. At September 30, 1999 the $4.5 million domestic line of credit and the
$750,000 foreign line of credit had outstanding balances of approximately $4.3
million and $0.7 million, respectively, bearing interest at 1.5% plus the bank's
corporate base rate (9.75% at September 30, 1999) per annum, payable monthly.
Advances under both lines are limited to a percentage of eligible accounts
receivable and inventory and are secured by our accounts receivable, inventory
and property and equipment. The foreign line of credit is guaranteed by the U.S.
Export-Import Bank, and both lines of credit are also guaranteed by certain of
our stockholders. See "Certain Transactions." The outstanding balances of both
lines of credit will be repaid with part of the proceeds of this offering.

     At December 31, 1998 we had $11.8 million of federal net operating loss
carryforwards which expire at various dates. We anticipate that the sale of
common stock in this offering coupled with prior sales of common stock will
cause an annual limitation on the use of its net operating loss carryforwards
pursuant to the change in ownership provisions of Section 382 of the Internal
Revenue Code of 1986, as amended. This limitation is expected to have a material
effect on the timing of our ability to use the net operating loss carryforward
in the
                                       33
<PAGE>   36

future. Additionally, our ability to use the net operating loss carryforward is
dependent upon our level of profitability, which cannot be determined.

     We believe that our existing sources of liquidity and net proceeds to us
from this offering will be sufficient to satisfy our expected working capital,
debt repayment requirements and capital expenditures needs for at least the next
12 months.

YEAR 2000 READINESS

     In preparation for the year 2000, we engaged in efforts to ensure that our
products and business systems properly recognize date-sensitive information in
the year 2000 and beyond. These efforts and their costs are described below. We
have not experienced any significant "year 2000 problems" with our products and
business systems and do not expect that we will do so in the future.

     State of Readiness. In 1999 we hired outside consultants to audit and
assess the ability of our hardware and software systems to operate properly in
the year 2000 and beyond. We investigated the year 2000 readiness of our
software, hardware and other significant vendors by requiring them to complete
questionnaires and submit internal year 2000 plans to insure no disruption would
occur in our supply chain. To date we have not encountered any material year
2000 issues or significant disruptions to our operations.

     Cost of Assessment and Remediation. We have incurred direct costs of less
than $100,000 in assessing and remediating year 2000 problems, and we do not
expect to spend more than $100,000 in the aggregate to complete the process.

     Risks. We could be exposed to a loss of revenues and our operating expenses
could increase if our products or business systems have year 2000 problems. Our
potential areas of exposure include products purchased from third parties,
information technology, including computers and software, and non-information
technology, including telephone systems and other equipment used internally. The
reasonably likely worst case scenario for year 2000 problems would be if a
significant defect exists in key hardware or software and if a solution for such
a problem were not immediately available.

     Contingency Plan. Although we have not experienced any year 2000-related
problems affecting our internal systems, we have developed contingency plans to
be implemented if our efforts to identify and correct year 2000 problems are not
effective. Depending on the systems affected, these plans include:

     - accelerated replacement of affected equipment or software;

     - short to medium-term use of back-up equipment and software or other
       redundant systems; and

     - increased work hours for our personnel or the hiring of additional
       information technology staff.

     The discussion of our efforts and expectations relating to year 2000
compliance are forward-looking statements. Our ability to achieve year 2000
compliance, and the level of incremental costs associated with compliance, could
be adversely affected by, among other things, the availability and cost of
external resources, third party suppliers' ability to modify proprietary
software and unanticipated problems not identified in our ongoing review.

INFLATION

     Increases in inflation generally result in higher interest rates and
operating costs. Higher interest rates on our borrowings would decrease the
profitability of our existing portfolio. We intend to retire our existing debt
with the proceeds of this offering thus limiting our exposure
                                       34
<PAGE>   37

to increases in interest rates. Our largest cost exposure is cost of net sales
on product sales. These costs are incurred with contract manufacturers on a
fixed cost basis. To date we believe that inflation has not had a significant
impact on our operations.

RESEARCH AND DEVELOPMENT

     Research and development costs are expensed as incurred. Prototype and beta
site units are also expensed. Production tooling and fixtures are capitalized.
Tooling and fixturing costs are accumulated as a prepaid asset in the financial
statements until the associated products are launched into production. At that
time the accumulated costs begin to amortize to expense over the estimated
useful life of the tool or fixture or the estimated life of the product,
whichever is shorter.

MARKET RISK

     To date we have not utilized derivative financial instruments or derivative
commodity instruments. We do not expect to employ these or other strategies to
hedge market risk in the foreseeable future. We invest our cash in money market
funds, which are subject to minimal credit and market risk. We believe that the
market risks associated with these financial instruments are immaterial.

     Our revolving lines of credit and certain other debt obligations are
subject to variable rate interest which could be adversely affected by increases
in rates, however, our intent is to pay off our debt from a portion of the
proceeds of this offering, which should minimize this interest rate risk.

     Most of our revenues are realized currently in U.S. dollars and are from
customers primarily in the United States. Therefore, we do not believe that we
currently have any significant direct foreign currency exchange rate risk.

                                    BUSINESS

THE COMPANY

     Mobility Electronics designs, develops and markets connectivity and remote
peripheral component interface, or PCI bus, technology and products for the
computer industry and for a broad range of related embedded processor
applications. The PCI bus is the electrical transmission path linking the
computer's central processing unit with its memory and other peripheral devices,
such as modems, disk drives and local area networks, or LANs. Our proprietary
Split Bridge(TM) technology consists of a Split Bridge(TM) link, typically two
customized semiconductors, known as application-specific integrated circuits, or
ASIC chips, two connectors and a high-speed, bi-directional cable. Our
technology for the first time allows the primary PCI bus of any computer to be
extended to a remote location with virtually no software or performance
degradation and enables architectural designs of computer systems and
applications that previously were not feasible. Unlike traditional communication
protocols such as Universal Serial Bus, or USB, IEEE 1394, Ethernet and small
computer systems interface, or SCSI, Split Bridge(TM) offers a combination of:

     - high performance, bi-directional gigabit speeds;

     - plug and play ease of use with no unique software requirements;

     - flexible architectural design choices;

     - minimal special size, heat and power requirements; and

     - cost effective pricing.

     Since Split Bridge(TM) technology extends the PCI bus, it can also
accommodate any of the traditional communication protocols in the remote
location as if they are attached to the primary PCI bus.

     Split Bridge(TM) technology is suitable for many applications, including
universal docking stations for portable and handheld computers, and potentially
desktop expansion, servers, routers, keyboard-video-mouse, or KVM, switches,
business machines, such as copiers and printers, test equipment, modular
computers and other applications that could benefit from extending the PCI bus.

     Our first major application for Split Bridge(TM) technology is the creation
of a new universal docking product category which allows portable computer users
to configure a flexible, high performance docking solution that meets their
individual needs, and more importantly, is compatible with essentially all makes
and models of portable computers.

     Our Split Bridge(TM) technology won PC Week's "Best New Technology" award
at the fall 1999 COMDEX trade show, and our flagship EasiDock(TM) 3000 universal
docking product was runner-up for the Byte.com "Best New Peripheral Award" at
the fall 1999 COMDEX show, the world's largest information technology event in
the computer industry. Our Split Bridge(TM) technology and its universal docking
application have also been selected as one of seven nominees for the "Technology
Achievement of the Year Award" at the Mobile Insights 2000 Conference to be held
in March 2000. Mobile Insights is a professional services company that focuses
on the mobile computing and data communications market.

     In addition to our Split Bridge(TM) technology products, we also design,
develop and market a range of connectivity and power products for portable
computers. Our current major customers include Buy.com, Compaq, CompUSA,
Gateway, Hewlett-Packard, Hitachi, IBM, Ingram Micro, Merisel, Microwarehouse,
Mitsubishi Electronics, NEC, Pinacor, Targus, Tech Data and Toshiba.

INDUSTRY BACKGROUND

  PCI Computer Architecture

     Today the most prevalent computer architecture, which is incorporated into
virtually all computer systems and in many related embedded processor
applications, uses the PCI bus. However, the PCI bus has a number of key
limitations, most notably a constraint on the number of lines, or circuits, and
loads that can be attached to it. Historically, these limitations have been
mitigated to some extent by attaching a bridge chip to the PCI bus, which in
turn permits a number of additional loads or peripherals to be attached to a
secondary PCI bus, which is also connected to the bridge chip. This procedure
has the major limitation of requiring the secondary PCI bus to be located on the
main PCI bus printed circuit board, or PCB, or attached physically by a
connector which enables extension of the secondary PCI bus to a maximum of
approximately three inches from the PCB. Consequently, the industry today faces
a number of physical and electrical constraints when designing a computer
system, and has been unable to move the secondary PCI bus more than a few inches
from the primary PCI bus. Additionally, traditional communication protocols,
which attempt to address these limitations, have numerous disadvantages since
they generally require a processor, extensive software and other related items.

  Universal Docking

     The portable computer market, which is the fastest growing segment of the
personal computer industry, could benefit from solutions that address the
inherent limitations on PCI bus architecture. Demand in this market has been
fueled by advances in computer technology and the demand for computer mobility.
According to IDC, a leading industry source, the market for portable computers,
excluding handheld devices, is expected to grow at a compounded annual growth
rate of 13.8% from 15.5 million units in 1998 to approximately 29.6 million
units in 2003. In addition, IDC forecasts that the handheld market will grow at
a compounded annual growth rate of over 39.8% from 6.6 million units in 1998 to
approximately 35.2 million units by 2003. Along with this unit growth, there is
an increasing dependence on portable computers. IDC reported that 74% of all
notebook computers sold in 1997 served as the user's primary computer.

     Coupled with this trend toward portability, there has been an increased
demand for computers that are smaller and lighter but have processing
functionality similar to that of the traditional desktop computer. To meet this
demand, there has been an increased use of peripheral and external devices such
as hard drives, CD-ROM drives, networking connections, printers, tape backup
units and USB devices which enable the core laptop to be smaller and lighter. To
make these smaller and lighter computers more convenient to use in the office
and home, port replicators and docking stations have been developed to allow
users to connect to networks, peripheral devices and external power sources,
providing users with all of the features and functionality of a traditional
desktop computer. Port replicators are simple devices that provide users with a
cable management system for peripherals such as full-sized keyboards, power
cords, mice and monitors. Docking stations include basic port replicator
features, as well as more advanced capabilities such as networking, PC card
slots, storage devices and internal power supplies. Attaching and releasing a
portable computer from a port replicator or docking station is typically a
one-step procedure that takes seconds to complete compared to the burdensome
task of attaching or releasing each external device separately. When a portable
computer is detached from a connectivity product, all external devices connected
to the connectivity product stay in place.

     To date, there has not been a provider of a standardized, complete,
cost-effective, quick-to-market connectivity solution. Computer original
equipment manufacturers, or OEMs, have historically designed port replicators
and docking stations internally and subcontracted

                                       37
<PAGE>   40

these products for assembly by various vendors. Because computer OEMs primarily
focus on providing portable computers with the latest technological capabilities
and strong price and performance characteristics, their development of port
replicators and docking stations is a secondary focus and often lack
state-of-the-art technology and innovation. These OEM-developed port replicators
and docking stations are generally expensive, lack configuration flexibility and
are often available only well after the computer model is launched.
Additionally, computer OEMs generally retool each generation of portable
computers and have not created standardized port replicators and docking
stations that are independent of manufacturer or model.

THE MOBILITY SOLUTION

  Split Bridge(TM) Technology

     Our Split Bridge(TM) technology allows the primary PCI bus of any computer
to be extended to a remote location with virtually no software or performance
degradation. This technology enables architectural designs of computer systems
and applications that previously were not feasible. The implementation of such
new solutions can potentially include replacing current bridge chips with Split
Bridge(TM) chips, integrating Split Bridge(TM) technology into other chips and
technologies or using Split Bridge(TM) technology to create new products and
product categories in a variety of potential applications.

     More specifically, Split Bridge(TM) technology eliminates many of the
physical and electrical constraints on a primary PCI computer bus and PCB, by
allowing one or more Split Bridge(TM) chips to be attached to the primary
computer PCI bus, with the mating Split Bridge(TM) chips installed at a remote
location along with the secondary PCI bus. Thus, all of the secondary PCI bus
loads and peripherals do not need to be attached to the primary PCI bus,
eliminating their respective constraints on the primary PCI bus PCB.
Additionally, Split Bridge(TM) technology substantially reduces the physical
space requirements on the primary PCB by eliminating the need for multiple
traditional bridge chip connections and allows the connecting cable to be small
and flexible.

     Split Bridge(TM) technology enables input/output devices, peripherals and
other technologies to be placed in multiple remote locations. Examples include
providing remote PCI expansion devices for desktop computers and integrating
Split Bridge(TM) technology into KVM switches. Split Bridge(TM) technology can
also potentially be used to enhance or expand the existing installed base of
PCI-based computers, routers and servers. Since routers and servers are one of
the fastest growing segments of the computer industry, and because they often
already require multiple bridges, the growth potential for Split Bridge(TM) in
the router and server segment could be quite large.

  Universal Docking

     We believe that our universal Split Bridge(TM) docking station product line
will advance the state-of-the-art in docking capability by enabling the user to
configure a docking system which incorporates standard docking station
functionality with the user's preferred peripheral devices and PCI expansion
capability. Our universal Split Bridge(TM) docking station is capable of being
upgraded due to its modular design, providing the user with enhanced
flexibility. Our universal docking station is designed to work with most
standard notebook computers and PCI-based computing devices, regardless of the
manufacturer or model.

     Our universal docking station provides end users with the flexibility to
configure virtually any type of desired docking system, including the ability to
convert almost any PCI-based portable computer into a full desktop system. This
creates a basis for a connectivity standard for the portable computer industry,
which would allow the user to replace the desktop computer with a fully
integrated, customizable mobile computing system. These universal

                                       38
<PAGE>   41

docking products also provide a range of docking options that were not
previously available for many of the existing installed base of portable
computers. Our solution further provides distributors, retailers and value-added
resellers with the ability to carry a limited number of universal and expandable
docking products, as opposed to many individual docking stations that only work
with one computer model. Thus, distributors, retailers and value-added resellers
can offer flexible choices to their customers and have products readily
available when new computer models become available, while at the same time
maintaining a limited SKU count. Finally, these products offer OEMs the ability
to create a standardized docking solution for portable computer models, and to
provide creative docking solutions.

TECHNOLOGY

     The heart of most computing architecture today and into the foreseeable
future is the PCI bus or a derivative of PCI. A traditional PCI computer
architecture together with our Split Bridge(TM) chip alternative is shown in the
following figure:

[A diagram of a printed circuit board will appear here. This diagram will
illustrate the ability of the Mobility Split Bridge(TM) chip to interface with a
remote secondary PCI bus rather than a traditional secondary PCI bus.]

     As shown above, the primary PCI bus is typically connected to a north
bridge chip, which in turn is connected to the central processing unit, or CPU,
memory and advanced graphic processor, or AGP, and various peripherals such as
audio peripherals, a card bus controller, LAN adapters, SCSI adapters, a bridge
chip and other devices. The bridge chip then connects to a secondary PCI bus
that can handle additional functions just like the primary PCI bus.

                                       39
<PAGE>   42

     The key limitations of traditional technology and architecture are:

     - the requirement that the primary and secondary PCI bus be on the same
       PCB, or be physically attached via a connector which limits the distance
       to approximately three inches; and

     - the limited number of allowable lines and loads on the PCI bus.

Thus, substantial expansion requires many bridges on the PCB, creating a variety
of physical and loading constraints. These constraints are the reason bridges
were invented in the first place, but their limitation is that they take up a
load on the bus and the secondary bus is on the same PCB as the primary PCI bus.
Split Bridge(TM) chips are like any other bridge chip, except they are divided
into two halves separated by a high speed link. Consequentially, Split
Bridge(TM) technology eliminates the requirement of having the secondary PCI bus
on the primary PCI bus PCB. As a result, multiple secondary PCI buses can be
created at a number of remote locations.

     The traditional and the Split Bridge(TM) approaches are shown in the figure
above. While a traditional bridge chip has many lines in and out of the chip,
typically over 60, on the same PCB, with Split Bridge(TM) technology, these
lines are reduced to 4, sent over a high-speed link at gigabit speed and
returned to the full number of lines at the remote PCI bus location. An
additional benefit of this technology is that it is transparent to software. No
operating system or device drivers are required since we actually move the PCI
bus. Thus, Split Bridge(TM) technology can replace traditional bridge chips in
many applications.

     Historically, the above limitations have been addressed by using a range of
communication protocols such as USB, IEEE 1394, Ethernet and SCSI. These
approaches are generally software intensive, require processors and are
applicable for only certain uses since they involve moving data as opposed to
extending the PCI bus. The following table illustrates the advantages of Split
Bridge(TM) architecture:

       two USB ports will have a full 12 Megabits per second, or Mbs, bandwidth,
       as opposed to a total of only 12 Mbs across all ports for a USB only
       product. A second product in this category will include the features
       listed above plus Ethernet-based, 10/100 base T networking. The suggested
       retail price for this product is expected to be $249 without Ethernet and
       $299 with Ethernet.

     - EasiDock(TM) 2000 Series/Desktop Expansion Products. These standalone
       products will allow the user to add two USB ports, three additional PCI
       expansion cards and four additional enhanced integrated drive
       electronics, or EIDE, drive bays to any portable computer. Thus, the user
       will have the capability to provide almost unlimited expansion capacity.
       The suggested retail price for this product line is expected to range
       from $399 to $499.

     - EasiDock(TM) 3000 Series. This product series will offer all the
       functionality of the EasiDock(TM) 1000 Series, except it will have two
       USB ports versus four, and also will offer expansion options including
       two EIDE expansion bays, which can be used for applications such as CD
       ROMs, storage, drives, two standard PCI expansion slots and two of our
       proprietary expansion card slots. The suggested retail price for this
       product is expected to be $499 without Ethernet and $549 with Ethernet.

     Custom Split Bridge(TM) Products

     We have historically worked closely with OEMs to provide a wide variety of
unique products and programs that use traditional connectivity technology. While
we have not begun commercial production shipment of our custom Split Bridge(TM)
products, we are currently marketing these solutions to a number of OEMs. These
products will include:

     Standard Card Bus Universal Dock Offering. These products will provide OEMs
with a docking solution for products that have no docking connector or no OEM
dock offering. Such products may be privately labeled at an OEM's request.

     Universal Expansion Modules. We will offer OEMs an expansion module option
that interfaces with a standard, low-end port replicator OEM product. This
module will provide OEMs with the opportunity to continue with a low cost,
standard port replicator that provides video, USB and other port replication
functions, while also offering a PCI expansion card and enhanced integrated
drive electronic or EIDE drive bay capability. This solution will eliminate the
need for OEMs to design and develop an expensive high end docking station with
such expansion capability, while offering the customer such option.

     Universal Desktop Expansion Module. These products will provide an
expansion module for desktop computers, providing PCI and drive bay expansion
capabilities.

     Chip On Board Programs. We will offer OEMs the possibility of installing
one of our ASIC chips on the computer motherboard, either independently or in
combination with DVI or other technologies. Also, OEMs or other chip technology
companies will be able to integrate our technology into other main motherboard
chips. These programs will generally take much longer to implement due to
computer design cycles.

     USB Products

     We currently offer two universal USB docking stations which provide the
portable computer user with basic connectivity in the home or office. These
products use standard industry technology, and thus operate at 12 Mbs, and
provide five USB ports as well as a PS/2 mouse, PS/2 keyboard, serial port and
printer port. The second of these products provides the above mentioned features
plus 10 base T Ethernet networking.

     USB is not currently capable of handling higher performance items such as
video, 100 base T networking and PCI and EIDE drive bay expansion capability. It
does, however, provide a lower cost product that is well suited for the consumer
and small business market and other niche applications. The suggested retail
price for this product is currently $149 without Ethernet and $199 with
Ethernet. Our EasiDock(TM) USB 200 has been selected as one of the nominees in
the peripheral category for the "2000 Mobility Awards" to be given by Mobile
Insights in March 2000.
                                       43

     Other Products

     We also offer a range of in-car/in-air chargers and monitor stands. The
in-car/in-air chargers allow the user to power and charge a portable computer in
a car or in an airplane that supports the Empower standard, the airline
industry's on-board computer product power standard.

PRODUCTS UNDER DEVELOPMENT

     We are currently in various stages of developing or planning the following
products:

     Split Bridge(TM) Products

          Next Generation EasiDock(TM) 1000 Series. We intend to replace the
     current EasiDock(TM) 1000 series with a product series that is expected to
     include all the current EasiDock(TM) 1000 features plus the addition of
     video and a mini PCI card slot for user expansion. We also plan to include
     additional USB capacity to provide for a full 12 Mbs on each USB port as
     opposed to 12 Mbs for each two USB ports. Subsequently, some of the USB
     ports will be replaced with USB 2.0 ports when USB 2.0 becomes available.

          Next Generation EasiDock(TM) 3000 Series. We intend to replace the
     current EasiDock(TM) 3000 series with the next generation EasiDock(TM) 3000
     Series when USB 2.0 becomes widely available. We plan to include all the
     current EasiDock(TM) 3000 features, plus integrated USB 2.0 with two full
     bandwidth USB ports and a newly integrated docking chip.

          ASIC Chips. We intend to offer several new ASIC chips. These
     developments will help us stay at the leading edge of universal docking and
     remote PCI bus applications. We intend to develop and market the following
     chips:

         - Chip On Board. We are currently working with LSI to combine our Split
           Bridge(TM) technology with LSI's SerDes technology to develop a
           single chip OEM solution for use on OEM motherboards and for
           non-docking applications. This product will be in a small package and
           will not have any of the docking functions, thus providing OEMs with
           a low-cost, small, single chip solution.

         - Integrated Dock Chip. We are also currently working with LSI to
           combine our Split Bridge(TM) technology with LSI's SerDes technology
           to develop a single docking chip for use in our range of docking
           products. We expect that this product will allow us to replace the
           need for an external SerDes, reducing cost and circuit board size
           requirements.

         - Dock on a Chip. We intend to develop a next generation chip which
           integrates Split Bridge(TM) and SerDes technology into other docking
           functions such as USB 2.0, networking, video, EIDE and other
           functions. The specific items that will be included will be
           determined based on the best information available at the time the
           development program is initiated. We expect that this program will
           substantially drive down the cost of all our Split Bridge(TM) docking
           products and reduce space requirements for the docking circuit board.

         - Other Chips. We are currently evaluating the potential of integrating
           Split Bridge(TM) technology into other intellectual property blocks,
           such as digital video, and expect to develop several of these
           options.

All of the chips described above are intended to be used throughout our docking
product family, as well as in other applications, generally increasing
capability and reducing cost.

                                       44
<PAGE>   47

     Next Generation EasiDock(TM) USB Product. This product is planned for
introduction when USB 2.0 becomes available and is intended to replace the
current EasiDock(TM) USB series. We plan to include all the EasiDock(TM) USB
features, plus the addition of a full parallel port, a 100 base T networking
option, video and other unique features. Based on the acceptance of USB
peripherals by the time this product is released, legacy port replication ports
may or may not be included.

     Retractable Cord Power Product. This product is a unique version of our
current in-car/in-air charger product line that can be used across all power
products. The Retractable Cord Power Product is expected to include an
innovative and unique mechanical feature, which will allow the user to "store"
the input and output cables of the user's adapter via a retractable cord system.
It is intended to be used in both model specific, which is 2 wire output, or
universal, which is 4 wire output, in-car/in-air charger configurations. Through
the use of creative industrial design, we believe this product will offer the
customer the smallest, self-contained in-car/in-air power adapter on the market.
This product would complement our current line of power products.

</TABLE>

     Targus and Ingram Micro each accounted for more than 10% of our total
revenues for the nine month period ended September 30, 1999. Targus distributes
a range of our products, on a private label basis, primarily to major retail
outlets and certain OEM fulfillment outlets worldwide. Ingram Micro distributes
a wide range of our products to value-added resellers, system integrators,
catalog houses, major retail outlets and certain OEM fulfillment outlets
worldwide.

SALES, MARKETING AND DISTRIBUTION

     Sales. We have a dedicated, senior level OEM sales person who, along with
top management, focuses on developing and expanding relationships with top tier
computer OEMs on a worldwide basis. We are pursuing the sale of our standard
products, whether Mobility branded or private labeled, and the sale of custom
products and chips on board with all OEMs on a worldwide basis.

     In North America, we use an internal sales organization and a sales
representative organization to penetrate the traditional two-tier distribution
channel, including Ingram Micro, Merisel, Pinacor and Tech Data. We leverage
major catalog houses such as CDW and OEM catalog programs such as Dell, top
retailers such as CompUSA and a broad range of value-added resellers and dealers
such as Insight and Propeller Portable Computers. We also work with major
corporations and key accounts as part of our strategic efforts.

                                       45
<PAGE>   48

     We also plan to aggressively pursue markets outside North America by
establishing strategic sales representatives and distribution or private label
arrangements in each significant geographic region. We plan to execute bundling
programs with major OEMs, drive manufacturers, selected related vendors and
synergistic suppliers to Mobility's market. We also plan to establish an
e-commerce capability and marketing program, including build to order
capability. Additionally, we plan to use website links to help maintain
relationships with related parties and OEMs, and will establish a "preferred
vendor" program for products that integrate into our universal docking products.

     In Europe, we distribute our products through a sales representative
arrangement through a company operated by several of our former employees, which
primarily focuses on the marketing and sales of our products.

     We also have entered into an agreement with Targus whereby Targus
distributes a range of our products in its worldwide distribution channels,
primarily to major retail outlets and certain OEM fulfillment outlets. This
agreement provides that we are the exclusive supplier to Targus for some of our
products, and that we will develop certain products for Targus on an exclusive
basis. Targus markets our products to its retail customers, which include Best
Buy Co., Circuit City Stores, CompUSA, Computer City(R), OfficeMax and Staples.

     Marketing. We intend to implement a variety of marketing activities in 2000
to aggressively market our new range of universal docking products. Such
activities include participation in major user groups and trade shows, key OEM
and distribution catalogs, distribution promotions, value added reseller and
information technology manager advertising, on-line advertising and banner ads,
direct mail and telemarketing and bundle advertisements with OEMs and related
product partners. In addition, we intend to implement a strong public relations
program to continually educate the market about us, our Split Bridge(TM)
technology and our products, with a major emphasis on timely product and news
releases, speaking opportunities and feature stories. Attending and speaking at
key trade shows, such as PC Expo and COMDEX, will provide a forum to provide
additional market education about us, our Split Bridge(TM) technology and our
products. We also intend to leverage our web site as a major marketing and
direct sales mechanism.

MANUFACTURING

     The proprietary components of our Split Bridge(TM) technology are
manufactured by our strategic partners. Philips supplies us with our Split
Bridge(TM) technology chips, and Molex supplies us with our high-speed cable and
connectors. Our USB product line, power products and monitor stands are supplied
by contract manufacturers in Taiwan. We have selected Solectron as our primary
contract manufacturing source for the universal docking product line. These
products are currently in the pre-production phase. Solectron has sourced
components and has built prototype units and customer evaluation units on
production lines that have been established for production of these products.

     In-house manufacturing activity has primarily been reduced to packaging and
fulfillment activity. Some product is shipped in bulk quantities which are not
packaged for delivery to our customers. These products are packaged in the
appropriate box with the corresponding operations manual and other product
documentation. We currently assemble one mechanical port replicator under a
contract with NEC. The volume levels on this product are too small to outsource
economically. We will continue to build this product in-house for the
foreseeable future.

COMPETITION

     Competition for our Split Bridge(TM) technology primarily comes from
traditional communications protocols, such as USB, IEEE 1394, Ethernet and SCSI.
These protocols are generally
                                       46
<PAGE>   49

well established, particularly in certain applications, and thus will provide
competition for our Split Bridge(TM) technology depending upon the application.

     The market for our universal docking products is relatively new and
emerging and we presently have few direct competitors. However, we expect that
the markets for our products will become increasingly competitive. The market
for computer products in general is intensely competitive, subject to rapid
change and sensitive to new product introductions or enhancements and marketing
efforts by industry participants. The principal competitive factors affecting
the markets for our product offerings include corporate and product reputation,
innovation with frequent product enhancement, breadth of integrated product
line, product design, functionality and features, product quality, performance,
ease-of-use, support and price. Although we believe that our products compete
favorably with respect to such factors, there can be no assurance that we can
maintain our competitive position against current or potential competitors,
especially those with greater financial, marketing, service, support, technical
or other competitive resources.

     We currently compete primarily with the internal design efforts of OEMs.
These OEMs, as well as a number of our potential non-OEM competitors, have
larger technical staffs, more established and larger marketing and sales
organizations and significantly greater financial resources than we have. We
believe that we have a proprietary position with respect to our Split Bridge(TM)
and universal docking technology, which could pose a competitive barrier for
companies seeking to develop similar products or sell competing products in our
markets.

PROPRIETARY RIGHTS

     Our success and ability to compete is dependent in part upon proprietary
technology. We rely primarily on a combination of copyright and trademark laws,
trade secrets, nondisclosure agreements and technical measures to protect our
proprietary rights. We have two issued patents and five U.S. patent applications
pending. The process of seeking patent protection can be expensive and time
consuming. There can be no assurance that patents will issue from pending or
future applications or that if issued, such patents will not be challenged,
invalidated or circumvented or that rights granted thereunder will provide
meaningful protection or other commercial advantage to us. Moreover, there can
be no assurance that any patent rights will be upheld in the future or that we
will be able to preserve any of our other intellectual property rights. We
typically enter into confidentiality agreements with our employees,
distributors, customers and potential customers, and limit access to, and
distribution of, our product design documentation and other proprietary
information. Moreover, we enter into noncompetition agreements with employees,
whereby the employees are prohibited from working for and sharing confidential
information with our competitors for a period of two years after termination of
their employment. Additionally, we believe that, due to the rapid pace of
innovation within the computer industry, the following factors also represent
protection for our technology:

     - technological and creative skill of personnel;

     - knowledge and experience of management;

     - name recognition;

     - maintenance and support of products;

     - the ability to develop, enhance, market and acquire products and
       services; and

     - the establishment of strategic relationships in the industry.

RESEARCH AND DEVELOPMENT

     Our future success depends on our ability to enhance existing products and
develop new products that incorporate the latest technological developments. We
work with customers and prospects, as well as partners and industry standards
organizations, to identify and implement new solutions that meet the current and
future needs of our customers. Whenever possible, our products are designed to
meet and drive industry standards to ensure interoperability. We intend to
continue to support industry standards integral to our product strategy as well
as drive new initiatives relating to remote bus technology.

     Our research and development efforts will focus on enhancing our current
technology for use in docking as well as other broad applications. These
enhancements will center on issues of speeds, distance, cost and integration. We
intend to develop internal and external resources to more fully integrate chip
design capabilities.

     Currently, our Split Bridge(TM) technology group consists of 17 people who
are responsible for architecture, hardware, software and quality. This group is
active in industry committees, special interest groups and other activities that
provide industry knowledge.

EMPLOYEES

     As of December 31, 1999 we had 46 full-time employees all located in the
United States, including 7 employed in operations, 22 in engineering, 5 in sales
and marketing and 12 in administration. We engage temporary employees from time
to time to augment our full time employees, generally in operations. None of our
employees are covered by a collective bargaining agreement. We believe we have
good relationships with our employees.

FACILITIES

     Our executive offices and operations are located in Scottsdale, Arizona.
This facility consists of approximately 38,712 square feet of leased space
pursuant to a lease for which the initial term expires on January 31, 2002. We
have the option to renew the lease for the present space for an additional two
years. Additionally, we lease an office in Scottsdale, Arizona, which was our
former executive office. This office has been sublet to a tenant for the balance
of the original lease term at a rate resulting in no net expense. We believe
that our facility is suitable and adequate for our current business activities
for the next several years.

LEGAL PROCEEDINGS

     We are not a party to any material legal proceedings.

     - Class II consists of Messrs. Dilworth, Harris and Hunt, who will serve
       until the annual meeting of stockholders to be held in 2002; and

     - Class III consists of Messrs. Doss and Mollo, who will serve until the
       annual meeting of stockholders to be held in 2003.

     At each annual meeting of stockholders beginning with the 2001 annual
meeting, the successors to directors whose terms will then expire will be
elected to serve from the time of election and qualification until the third
annual meeting following election and until their successors have been duly
elected and qualified any additional directorships resulting from an increase in
the number of directors will be distributed among the three classes so that, as
nearly as possible, each class will consist of an equal number of directors.

COMMITTEES OF THE BOARD OF DIRECTORS

     The compensation committee of the board of directors consists of Messrs.
Dilworth and Hunt. The compensation committee makes recommendations to the board
concerning salaries and incentive compensation for our executive officers,
directors, employees and consultants and administers our 1996 Plan.

     The audit committee of the board of directors consists of Messrs. Harris
and Steel. The audit committee aids management in the establishment and
supervision of our financial controls, evaluates the scope of the annual audit,
reviews audit results, makes recommendations to our board of directors regarding
the selection of independent auditors, consults with management and our
independent auditors prior to the presentation of financial statements to
stockholders and, as appropriate, initiates inquiries into aspects of our
financial affairs.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Neither Messrs. Dilworth or Hunt, who are members of our compensation
committee, has at any time been an officer or employee of Mobility. None of our
executive officers serves as a member of the board of directors or compensation
committee of any entity which has one or more executive officers serving as a
member of our board of directors or compensation committee. For a description of
the transactions between Mobility and any member of the compensation committee
and entities affiliated with any compensation committee member, see "Certain
Transactions."

DIRECTOR COMPENSATION

     Each director who is also our employee does not receive additional
compensation for serving as a director. Each non-employee director, upon initial
election to the board, will receive a non-qualified option to purchase 20,000
shares of common stock, which will be fully exercisable on the one-year
anniversary of the date of grant (if that director is then serving as a
director). In addition, each non-employee director will receive a non-qualified
option to purchase 30,000 shares of common stock at the annual meeting of our
stockholders following the initial year of service as a director, and every
fourth year thereafter, which option will vest 25% annually, commencing on the
date of grant of the option with vesting occurring only on continuous service.
At each annual meeting of our directors, each non-employee director who is
elected to serve on either the audit committee or the compensation committee
will receive an option to purchase 5,000 shares of common stock, which option
shall be fully exercisable at the end of the one-year term of that office (with
vesting occurring only on continuous service). Directors may also be reimbursed
for certain expenses in connection with attendance at board and committee
meetings.

     We have entered into consulting agreements with Messrs. Hunt and Dilworth.
The agreement with Mr. Dilworth expires on May 20, 2001. The agreement with Mr.
Hunt expires

                                       51
<PAGE>   54

on December 7, 2001. The agreements may be terminated by either party to the
agreement at any time as long as 30 days written notice is given to the other
party to the agreement. As compensation for entering these agreements, we
granted each of Messrs. Hunt and Dilworth the option to purchase 70,000 shares
of our common stock under our 1996 Plan. Mr. Hunt's options were granted at an
exercise price of $2.00 per share. Mr. Dilworth's options were granted at an
exercise price of $4.00 per share. These options expire on the same day that the
consulting agreements expire. The consulting agreements provide that we will
reimburse Messrs. Hunt and Dilworth for all reasonable and necessary
out-of-pocket travel and other expenses they incur while performing their duties
and state that Messrs. Hunt and Dilworth are independent contractors.

EXECUTIVE COMPENSATION

     The following table sets forth the compensation awarded to, earned by or
accrued for services rendered to us in all capacities during the years ended
December 31, 1997, 1998 and 1999 by our Chief Executive Officer and the two

$100,000 in fiscal 1999 (collectively, the "Named Executive Officers") for

AMENDED AND RESTATED 1996 LONG TERM INCENTIVE PLAN

     Our Amended and Restated 1996 Long Term Incentive Plan, or the 1996 Plan,
authorizes the granting of options intended to qualify as incentive stock
options within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended, options that do not so qualify ("non-qualified stock options") and
restricted stock awards to our directors, key employees and advisors. The 1996
Plan is administered by the compensation committee, which is, and shall be,
comprised of at least two non-employee directors as may be appointed by the
Board (the "Committee"). The Committee generally has the authority to fix the
terms and number of options and restricted stock awards to be granted and to
determine the employees or other persons who will receive awards; provided that
non-employee directors receive non-qualified stock options under the 1996 Plan
automatically upon election as a director and upon each annual meeting of the
stockholders thereafter while he or she continues to serve as an independent
director. The aggregate number of shares of common stock for which options may
be granted or for which stock grants may be made under the 1996 Plan is
2,500,000. The 1996 Plan will terminate in 2008, unless sooner terminated by the
board.

     Each option granted pursuant to the 1996 Plan is exercisable at any time
upon or after vesting and expires on the date determined by the compensation
committee. In no event will any option expire later than ten years from the date
of grant. In no event will any option granted to a person who, on the date of
grant of the option, owns stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of us, expire later than
five years from the date of grant. With respect to a participant who is an
employee or advisor, each option expires within three months after the date the
participant ceases to be an employee or advisor. During that three month period,
those options may only be exercised if they were exercisable immediately prior
to the time the employment was terminated. If the employee's, advisor's or
non-employee director's employment is governed by an employment agreement and is
terminated for "cause," the option will automatically expire. The exercise price
of each option granted will be determined by the compensation committee, but
shall not be less than 100% of the fair market value of the common stock at the
time such option is granted. In the case of an incentive stock option granted to
a person who, on the date of the grant owns more than 10% of us or any of our
subsidiaries, the exercise price shall not be less than 110% of the fair market
value of the common stock at the time such incentive stock option is granted.
Options are not transferable other than by will or the laws of descent or

                                       53
<PAGE>   56

distribution or to a beneficiary, as defined in the plan, in the event of the
participant's death. Options may not be pledged, mortgaged, hypothecated or
otherwise encumbered, and shall not be subject to the claims of creditors.
Options may be exercised during the lifetime of the optionee only by the
optionee or the optionee's authorized representative. A vesting schedule for the
options is indicated in each option agreement as determined by the compensation
committee.

     Shares of common stock awarded under restricted stock grants are subject to
restrictions prohibiting their sale, assignment, transfer or encumbrance for a
period of time specified by the compensation committee and will revert to us if
the participant's relationship with us terminates during such period of
restriction, unless the compensation committee, by rule or regulation or in any
award agreement, provides otherwise.

     As of December 31, 1999 we had outstanding options to purchase in the
aggregate 1,655,455 shares of common stock under the 1996 Plan, 286,567 of which
are vested and exercisable. We expect that options will continue to be granted
to eligible persons as part of our incentive-based compensation program.

FOUNDERS OPTIONS

     Several key managers have received nonqualified options to purchase an
aggregate of 264,396 shares of common stock at a price per share of $1.76
outside the 1996 Plan. These options vested from August 23, 1996 to June 1,
1999.

EMPLOYMENT AGREEMENTS

     We have entered into full-time employment agreements with Messrs. Mollo,
Doss and Winterich. The agreements with Messrs. Mollo and Doss expire on
November 30, 2001. The agreement with Mr. Winterich expires on December 31,
2001. When the agreements have expired, they will be renewed on a year-to-year
basis unless either party to the agreement gives the other party notice of
termination at least 90 days prior to the end of the then current term, as
defined in the agreement. The employment agreements provide for increases in
salary as determined by the board of directors.

     As of December 1, 1999 Mr. Mollo's base salary is $200,000. His salary will
automatically be increased $25,000 per year upon the completion of this initial
public offering. If we have positive net income for fiscal year 2000, Mr.
Mollo's salary must be increased by at least 7%, effective December 1, 2000. Mr.
Mollo is entitled to an annual cash bonus, for each fiscal year that the
agreement is in effect, of up to 50% of his then current base salary. Under the
terms of his employment agreement, we granted Mr. Mollo the option to purchase
200,000 shares of our common stock at $2.00 per share under our 1996 Plan. This
option expires on December 8, 2003.

     As of December 1, 1999 Mr. Doss's base salary is $180,000. Mr. Doss is
entitled to an annual increase in salary of at least 7.0% which will take effect
each year on December 1. Mr. Doss is further entitled to an annual cash bonus
for each fiscal year that the agreement is in effect. Mr. Doss is entitled to
0.4% of actual margin contributions provided by all original equipment
manufacturer sales which consist of unique and chip on board sales (but not
standard product programs) for which Mr. Doss has had primary and direct
responsibility. We will also pay to Mr. Doss a cash bonus of either 15% of his
salary, as of the end of the fiscal year, if we attain at least 90.0% of our
budgeted gross profit margin for that particular fiscal year, or 25.0% of his
salary, as of the end of the fiscal year, if we attain 100.0% of our budgeted
margin for that particular fiscal year. Under the terms of his employment
agreement, we granted Mr. Doss the option to purchase 150,000 shares of our
common stock at $2.00 per share under our 1996 Plan. This option expires on
December 8, 2003. Pursuant to Mr. Doss's employment agreement, we sold him
50,000 shares of our Series C preferred stock
                                       54
<PAGE>   57

at a purchase price of $6.00 per share and issued Mr. Doss a warrant to purchase
100,000 shares of our common stock at an exercise price of $0.01 per share. In
return, Mr. Doss provided us with a promissory note and an agreement pledging
his 50,000 shares of common stock to us.

     If we terminate our employment agreement with Mr. Mollo or Mr. Doss for any
reason other than just cause, as defined in the agreement, within two years of
experiencing a change-in-control, as defined in the agreement, we will pay a
lump-sum payment equal to his then current salary for the remainder of the then
current term of the agreement. If Mr. Mollo or Mr. Doss terminates his
employment agreement with us for constructive termination, as defined in the
agreement, within two years of the time that we experience a change-in-control,
as defined in the agreement, we will also pay him a lump-sum payment equal to
his then current salary for the remainder of the then current term of his
employment agreement.

     We have agreed to consult with Mr. Doss regarding any change of our current
chief executive officer. If Mr. Doss does not approve of the new chief executive
officer, he is entitled to terminate his employment with us within thirty days
of the time the new chief executive officer takes office. Mr. Doss will retain
the compensation he has earned until that point and we will pay to Mr. Doss a
lump-sum equal to three months of his then current salary.

     As of January 1, 1999 Mr. Winterich's base salary is $185,000. Mr.
Winterich is entitled to an annual calendar year cash bonus of 25% of his then
current salary. Under the terms of his employment agreement, we granted Mr.
Winterich the option to purchase 100,000 shares of our common stock at $2.00 per
share under our 1996 Plan. This option vests and becomes exercisable over a
period of three years from the date of grant and expires on April 12, 2004,
unless it expires earlier due to Mr. Winterich terminating his employment with
us. Mr. Winterich also has the option to purchase 50,000 additional shares of
our common stock at a price of $0.01 per share when we consummate this offering,
experience a change-in-control, have a strategic partner or investor invest
$10.0 million in us or on December 31, 2007, whichever occurs first. This option
vests and becomes exercisable over a period of two years from the date of grant
and expires on April 12, 2009, unless it expires earlier due to Mr. Winterich
terminating his employment with us.

 (1) "Beneficially" owned shares, as defined by the SEC, are those shares as to
     which a person has voting or dispositive power, or both. "Beneficial"
     ownership does not necessarily mean that the named person is entitled to
     receive the dividends on, or the proceeds from the sale of, the shares.

 (2) This calculation is the quotient of (a) the number of shares currently
     beneficially owned by the named individual or group, plus the number of
     shares, if any, for which options beneficially held by such person or group
     are exercisable within 60 days or upon the closing of an initial public
     offering, divided by (b) the total number of shares outstanding at December

                              CERTAIN TRANSACTIONS

     The following is a description of transactions since our inception, to
which we have been a party, in which the amount involved in the transaction
exceeds $60,000 and in which any of our directors, executive officers or holders
of more than five percent of our capital stock had or will have a direct or
indirect material interest, other than compensation arrangements that are
otherwise required to be described under "Management."

     In September 1995 our predecessor, Electronics Accessory Specialists
International, L.L.C. ("Predecessor"), was capitalized with commitments from
members of our management, our directors and advisors and their respective
affiliates to subscribe for $970,000 of common and preferred interests in
Predecessor, at which time a group of outside investors committed to contribute
an additional $1,050,000 for such securities. In April 1996, we completed an
additional $1.0 million round of financing, $650,000 of which was subscribed for
by members of our management, our directors and advisors and their respective
affiliates, and $350,000 of which was subscribed for by outside investors, in
the form of a super preferred interests in Predecessor.

     In connection with the merger of Predecessor with and into us in August
1996, the common and preferred interests in Predecessor were converted into
shares of common stock, Series A preferred stock and Series B preferred stock,
and all outstanding options to purchase common interests in Predecessor were
converted into similar interests to purchase shares of common stock of us.

     From September 1996 through May 1997 we raised approximately $1.9 million
from our management and their affiliates (approximately $1.3 million of which
was in the form of common stock, at a purchase price of $3.86 per share, and
$565,000 of which was in the form of convertible subordinated debt (the
"Convertible Debentures")), and approximately $2.1 million from outside
investors ($846,458 of which was in the form of common stock, at a purchase
price of $3.86 per share, and approximately $1.3 million of which was in
Convertible Debentures). For a description of the Convertible Debentures, see
"Description of Capital Stock -- Convertible Debentures."

     In 1996 the holders of Series A preferred stock converted such shares into
common stock, at the rate of $3.86 per share, and Convertible Debentures at the
rate of $3.86. Management and its affiliates converted all $605,772 of its
Series A preferred stock into common stock, and outside investors converted
$87,855 into common stock and $306,374 into Convertible Debentures. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

     From September through November 1997 we completed a $10.0 million private
placement, including $583,885 of notes which were converted at $4.00 per share,
approximately $1.1 million of already outstanding preferred stock which was
converted at $4.00 per share and the sale of 2,081,114 newly-issued shares of
common stock at $4.00 per share. Of these amounts, management converted notes of
$525,100, preferred stock of approximately $1.1 million and purchased $16,000 of
common stock, all at $4.00 per share.

     In June 1998 we completed a private placement of approximately $8.5 million
and issued an aggregate of 1,485,000 shares of common stock at $5.75 per share.
Our management and their affiliates purchased an aggregate of 74,000 shares of
common stock ($425,000) in this private placement.

     In December 1998 we offered to convert 100% of the Convertible Debentures
and accrued interest thereon to common stock at a price of $3.86 per share. Of
the approximately $2.1 million of principal outstanding, approximately $2.0
million plus accrued interest of $62,448 was converted into 551,443 shares of
common stock. Our management and their

                                       58
<PAGE>   61

affiliates converted $545,000 of principal and $16,476 accrued interest into
145,460 shares of common stock.

     In January 1999 we completed a private placement of approximately $5.0
million and issued an aggregate of 735,300 shares of Series C preferred stock at
$6.75 per share. Our management and their affiliates purchased an aggregate of
45,000 shares of Series C preferred stock ($303,750) in this private placement.
Pursuant to the terms of the Series C preferred stock, an additional 91,909
shares were issued to the investors in such private placement as a result of a
subsequent round of financing at the lower price of $6.00 per share and 5,625 of
such additional shares were issued to management and their affiliates. See
"Description of Capital Stock -- Series C Preferred Stock."

     In March 1999 we raised $3.5 million in the form of 13% Bridge Promissory
Notes, of which $975,000 was from our management and their affiliates and the
balance from outside investors. Of the amount held by management and their
affiliates $135,000 was converted to 33,750 shares of common stock at a price of
$4.00 per share in June 1999. The offering also included the issuance of
warrants to purchase 1,050,000 shares of common stock at a price of $0.01 per
share, of which 292,500 were issued to our management and their affiliates. See
"Description of Capital Stock -- Private Placement of 13% Bridge Promissory
Notes and Warrants and Series C Preferred Stock."

     In January 2000 we completed a private placement of approximately $7.3
million and issued an aggregate of 1,222,450 shares of Series C Preferred Stock
at $6.00 per share. For each share of Series C Preferred Stock purchased, an
investor received a warrant to purchase two shares of common stock at a price of
$0.01 per share. Our management and their affiliates purchased an aggregate of
159,167 shares of Series C preferred stock ($955,006) in this private placement
and received warrants for the purchase of 318,334 shares of common stock at a
price of $0.01 per share. See "Description of Capital Stock -- Series C
Preferred Stock."

     In April 1998 in connection with the Bank of America line of credit,
certain shareholders including Messrs. Mollo and Doss executed personal
guarantees to guarantee a total of approximately $1.8 million each. In April
1998 certain of our other stockholders agreed to indemnify such guarantors
against amounts paid under such guarantees up to certain agreed upon levels. As
part of such guarantees and indemnification arrangements, such persons were
issued an aggregate of 225,000 warrants to purchase common stock at a price of
$5.75 per share. Our management of the Company and their affiliates received an
aggregate of 173,241 of such warrants.

     When the Bank of America line of credit was amended in November 1999,
certain shareholders including Messrs. Mollo and Doss executed personal
guarantees to guarantee a total of approximately $1.8 million each, and certain
other stockholders continued to indemnify such guarantors against amounts paid
under such guarantees up to certain agreed upon levels. As part of such
guarantees and indemnification arrangements, such persons were issued an
aggregate of 112,000 warrants to purchase common stock at a price of $2.00 per
share. Our management and their affiliates received an aggregate of 102,222 of
such warrants.

     We have entered into an employment agreement with Messrs. Doss, Mollo and
Winterich. See "Management -- Employment Agreements."

     As provided for in Mr. Doss's employment agreement, we have entered into a
promissory note in the principal sum of $300,000 in December 1999 with Mr. Doss,
our Executive Vice President, to finance his purchase of 50,000 shares of our
Series C preferred stock at a purchase price of $6.00 per share. This note
provides for 6.0% per annum interest and is due in full on December 1, 2001,
however, Mr. Doss may prepay at any time without any penalty or premium. The
principal amount outstanding as of December 31, 1999 is $300,000. In

                                       59
<PAGE>   62

connection with the note, Mr. Doss and the Company have also entered into a
pledge agreement granting a security interest in the preferred stock and the
warrant we sold to Mr. Doss.

     We have granted options to certain of our directors and executive officers.
We have also entered into an indemnification agreement with each of our
directors and executive officers.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     We are a Delaware corporation and our affairs are governed by our
certificate of incorporation, as amended, our bylaws, as amended, and the
Delaware General Corporation Law (the "DGCL"). The following description of our
capital stock is qualified in all respects by the certificate of incorporation
and the bylaws, which have been filed as exhibits to the registration statement
to which this prospectus forms a part.

     Our authorized capital stock consists of 100,000,000 shares of common
stock, par value $0.01 per share, and 15,000,000 shares of preferred stock, par
value $0.01 per share.

COMMON STOCK

     As of December 31, 1999 we had 11,957,358 shares of common stock
outstanding and approximately 495 holders of common stock. All issued and
outstanding common stock is, and all shares of common stock to be outstanding
upon completion of this offering will be, fully paid and nonassessable. Holders
of shares of common stock are entitled to one vote per share on all matters
submitted to a vote of our stockholders. There is no right to cumulative voting
for the election of directors. Holders of shares of common stock are entitled to
receive dividends, if, as and when declared by the board of directors out of
funds legally available therefor, after payment of dividends required to be paid
on any outstanding shares of preferred stock. Upon our liquidation, holders of
shares of common stock are entitled to share ratably in all assets remaining
after payment of liabilities, subject to the liquidation preferences of any
outstanding shares of preferred stock. Holders of shares of common stock have no
conversion, redemption or preemptive rights. The rights of the holders of common
stock will be subject to, and may be adversely affected by, the rights of the
holders of preferred stock.

PREFERRED STOCK

     The board of directors may, without further action of our stockholders,
issue shares of preferred stock in one or more series and fix or alter the
rights and preferences thereof, including the voting rights, redemption
provisions (including sinking fund provisions), dividend rights, dividend rates,
liquidation preferences, conversion rights and any other rights, preferences,
privileges and restrictions of any wholly unissued series of preferred stock.
The board of directors may, without further action by our stockholders, issue
shares of preferred stock which it has designated. The rights of holders of
common stock will be subject to, and may be adversely affected by, the rights of
holders of preferred stock. While the issuance of preferred stock provides
flexibility in connection with additional financing, possible acquisitions and
other corporate purposes, future issuances may have the effect of delaying,
deferring or preventing the change of control in us without further action by
the stockholders and may discourage bids for the common stock at a premium over
the market price. The board of directors may, without stockholder approval,
provide for the issuance of preferred stock that could have voting, conversion
or other rights superior to the rights of holders of common stock.

     We have no present plans to issue any new series of preferred stock.

SERIES C PREFERRED STOCK

     As of December 31, 1999 we had 4,500,000 shares of Series C preferred stock
authorized for issuance and 2,399,102 shares of Series C preferred stock
outstanding and 200 holders of Series C preferred stock. All issued and
outstanding Series C preferred stock is, and all shares

                                       61
<PAGE>   64

of Series C preferred stock to be outstanding upon completion of this offering
will be, fully paid and nonassessable.

     The Series C preferred stock is convertible into shares of common stock.
The rate of conversion is 1-to-1.3763 as of December 31, 1999. The initial
conversion rate is one for one, but is subject to change if certain events
occur. Generally, the conversion rate will be adjusted if we issue any non-cash
dividends on our securities, split our securities or otherwise effect a change
to the number of our outstanding securities. The conversion rate will also be
adjusted if we issue additional securities at a price that is less than the
price that the Series C preferred stockholders paid for their shares. Such
adjustments will be made according to certain formulas that are designed to
prevent dilution of the Series C preferred stock. The Series C preferred stock
can be converted at any time at the option of the holder, and will convert
automatically, immediately prior to the consummation of a firm commitment
underwritten public offering of our common stock pursuant to a registration
statement filed with the SEC having a per share price equal to or greater than
$12.00 per share and a total gross offering amount of not less than $15.0
million. No fractional shares will be issued upon conversion.

     If our board of directors declares a cash dividend payable on our
outstanding shares of common stock, the board of directors must also declare a
dividend payable on each share of Series C preferred stock equal to the amount
of the dividend payable on the number of shares of common stock into which each
such share could then be converted. Holders of shares of Series C preferred
stock are entitled to vote on all matters submitted for a vote of the holders of
common stock. Holders will be entitled to one vote for each share of common
stock into which one share of Series C preferred stock could then be converted.
In the event of our liquidation or dissolution, the holders of Series C
preferred stock will be entitled to receive the amount they paid for their
stock, plus accrued and unpaid dividends out of our assets legally available for
such payments prior to the time other holders of our securities will be entitled
to any payments. We are restricted from undertaking certain corporate actions
while any shares of Series C preferred stock remain outstanding.

WARRANTS AND OPTIONS

     Finova Warrants. In connection with a $1.6 million loan made by Finova on
June 24, 1997 to us (the "Finova Loan"), we issued a Stock Purchase Warrant to
Finova (the "First Finova Warrant") to purchase 171,698 shares of common stock,
at $0.01 per share, subject to the following adjustments: if the Finova Loan
remains outstanding on June 24, 1999, Finova would have the right to purchase
231,288 shares of common stock; if the Finova Loan remains outstanding on June
24, 2000, Finova would have the right to purchase 292,176 shares of common
stock; and if the Finova Loan remains outstanding on June 24, 2001, Finova would
have the right to purchase 354,322 shares of common stock. The First Finova
Warrant is exercisable at any time until July 31, 2002. Pursuant to the terms of
the First Finova Warrant and the Second Finova Warrant (defined below)
(collectively with the First Finova Warrant, the "Finova Warrants"), Finova is
entitled to receive notice of and be entitled to attend or to send a
representative to attend all meetings of our board of directors in a non-voting
observation capacity, receive copies of all notices, packages and documents
provided to members of our board of directors for each board meeting and receive
copies of all actions taken by written consent of our board of directors, until
such time as the Finova Loan has been paid in full. Additionally, both Finova
Warrants contain certain provisions that protect the holder against dilution by
adjustment of exercise price and the number of shares of common stock subject to
the Finova Warrants in certain events, such as stock dividends and
distributions, stock splits, recapitalizations, mergers or consolidations. We
also granted to Finova an option to sell (the "Put") to us the Finova Warrants
for a period of 30 days immediately preceding the expiration of the Finova
Warrants at a purchase price equal to fair market value (as defined therein);
however, upon consummation of this offering, the Put will terminate.
Additionally, we have

                                       62
<PAGE>   65

granted certain registration rights to Finova in connection with the Finova
Warrants. Effective March 25, 1998 we entered into the First Amendment to the
Loan Agreement and Loan Documents with Finova Capital Corporation whereby the
principal amount of the loan was increased by approximately $1.8 million to a
total of approximately $3.4 million. In connection with the additional loan, a
Stock Purchase Warrant to Finova the ("Second Finova Warrant") was issued which
provides that Finova may purchase 186,836 shares of common stock, subject to the
following adjustment: if the Finova Loan remains outstanding on June 24, 2000,
Finova would have the right to purchase 283,143 shares of common stock; if the
Finova Loan remains outstanding on June 24, 2001, Finova would have the right to
purchase 381,456 shares of common stock; and if the Finova Loan remains
outstanding on June 24, 2002, Finova would have the right to purchase 481,839
shares of common stock. This warrant is exercisable at any time until July 31,
2002 and the exercise price is $0.01 per share of common stock.

     Other Warrants. To date we have issued and outstanding warrants to purchase
a total of 5,172,778 shares of common stock, at exercise prices ranging from
$0.01 per share to $7.00 per share.

     Options. To date we have issued and outstanding options to purchase
1,919,851 shares of common stock. The exercise prices of these options range
from $0.01 to $5.75 per share. See "Management -- Option Grants in Last Fiscal
Year," "-- Amended and Restated 1996 Long Term Incentive Plan," "-- Founders
Options" and "-- Employment Agreements" for a description of options granted by
us.

CONVERTIBLE DEBENTURES

     In late 1996 and early 1997 we issued approximately $2.1 million in
aggregate principal amount of 12% Convertible Debentures to various investors
(the "Convertible Debentures"). In December 1998 approximately $2.1 million was
converted to common stock at a price of $3.86 per share. The remaining
Convertible Debentures ($95,000) require the Company to pay interest quarterly
at a rate of 12% per annum. Beginning on the second anniversary of the date of
issuance of each Convertible Debenture, we are required to pay 20 equal
quarterly installments of principal and accrued but unpaid interest in an amount
necessary to fully amortize the notes by the twentieth installment, when all
remaining principal and accrued interest will be due. Each of the Convertible
Debentures may be prepaid at our option at any time upon 30 days' notice to the
holder. Unless prepaid by us, each Convertible Debenture also can be redeemed at
the holder's option in whole or in part upon the closing of this offering (the
"IPO Redemption Option"). Such redemption price would be equal to 100% of the
principal amount of the Convertible Debentures to be redeemed, plus accrued
interest, if any, to the date of the closing of this offering; provided,
however, that the IPO Redemption Option will terminate at the close of business
on the date of the closing of this offering and will be lost if not exercised by
that time. The IPO Redemption Option may be exercised separately or in
conjunction with the conversion right described below.

     Unless the Convertible Debenture is prepaid by us, 60% of the outstanding
principal balance of each Convertible Debenture is convertible, at the option of
the holder, into common stock on the date of the closing of this offering at the
rate of one share of common stock for each $3.86 of principal of each
Convertible Debenture (but just the 60% convertible portion thereof); provided,
however, that the right to convert each Convertible Debenture will terminate at
the close of business on the date of the closing of this offering and will be
lost if not exercised prior to that time. We have received commitments from the
holders of the Convertible Debentures to convert 60% of the outstanding
principal balance of each Convertible Debenture concurrent with the closing of
this offering.

REGISTRATION RIGHTS

     Finova Warrants. The Finova Warrants contain a registration rights
provision that allows Finova to request that we register all or any part of the
shares of common stock issuable upon exercise of the Finova Warrants as
described above (the "Finova Shares") in certain circumstances. Specifically,
Finova can request that we register the Finova Shares if we propose to file a
registration statement on a form suitable for a secondary offering of shares. We
are required to notify Finova of our intention to file such a registration
statement at least thirty days prior to such filing. If Finova requests that we
register some or all of the Finova Shares, we must include the Finova Shares in
such registration statement at our expense; provided, however, that if the
offering being registered is underwritten and the representative of the
underwriters certifies in writing that the inclusion of the Finova Shares would
materially and adversely affect the sale of the securities to be sold by us in
the offering, then we will be required to include in the offering only the
number of Finova Shares that the underwriters determine in their sole discretion
will not jeopardize the success of the offering.

     Miram International, Inc. On July 29, 1997 we entered into a registration
rights agreement with Miram International, Inc., or Miram. Pursuant to this
agreement, we are obligated to register 187,000 shares of common stock (the
"Miram Shares") held by Miram in certain circumstances.

     Miram can request that we register the Miram Shares if we propose to file
certain types of registration statements at any time after we become a reporting
company under the Exchange Act. If such a request is made, we are required to
use our best efforts to cause any managing underwriter of such a proposed
underwritten offering to permit Miram to include the Miram Shares in the
offering. However, no such registration will be required if the managing
underwriter for the proposed offering determines that the inclusion of the Miram
Shares could have an adverse effect on the marketability or the price of the
securities otherwise included in the offer. If the contemplated registration
does not involve an underwritten public offering, such determination shall be
made by us in our reasonable discretion. If requested by the managing
underwriter, Miram has agreed to use its best efforts not to effect any public
sale or distribution of the Miram Shares within 10 days before or 90 days after
the effective date of an underwritten public offering in which any Miram Shares
are included. Expenses incurred in connection with the registration of the Miram
Shares generally will be borne by us. These registration rights will terminate
upon the earlier of the sale of all or substantially all our assets or our
merger with and into another business entity or December 31, 2000.

     Private Placement of Common Stock and Warrants. In November 1997 we
completed a private placement of 2,500,000 shares of common stock and 625,000
warrants to various members of our management, other individuals and
institutional investors. In June 1998 we completed a private placement of
1,485,000 shares of common stock to various members of our management, other
individuals and institutional investors. Pursuant to purchase agreements
executed by the holders of these securities, if we proposes to register any of
our common stock or other securities in connection with the public offering of
such securities solely for cash, other than an initial public offering or
certain other types of offerings, we shall promptly give each holder written
notice of such proposed filing. Upon the timely request of each holder, we must,
subject to certain exceptions, cause such securities to be registered. If such
offering is underwritten, we will not be required to include any of these
securities in the offering unless the holder accepts the terms of the
underwriting and then only in such quantity as the underwriters determine in
their sole discretion will not materially jeopardize or in any way reduce the
success of the offering. Expenses incurred in connection with the registration
of these securities will be borne by us. Assignment of these registration rights
is permitted in certain instances. Additionally, each holder has agreed that it
will not sell any of these securities until 120 days after the earlier of the
effective registration of these securities
                                       64
<PAGE>   67

or the effective date of a registration statement in which these securities
could have been included. These registration rights will terminate three years
after we become a public company.

     Private Placement of 13% Bridge Promissory Notes and Warrants and Series C
Preferred Stock. In March 1999 we issued in a private placement approximately
$3.5 million of our 13% Bridge Promissory Notes together with warrants to
purchase 1,050,000 shares of our common stock (the "March Note Placement"). In
June 1999 holders of approximately $2.3 million of the 13% Bridge Promissory
Notes issued in connection with the March Note Placement converted their notes
and accrued interest thereon of approximately $96,000 were converted to 592,685
shares of common stock. In July 1999 we completed the private placement of
approximately $3.7 million of our 13% Bridge Promissory Notes together with
warrants to purchase 898,400 shares of our common stock (the "July Note
Placement"). Additionally, in connection with the July Note Placement, holders
of approximately $3.2 million of such notes converted their notes into 788,125
shares of common stock. In January 2000 we completed the private placement of
2,085,732 shares of our Series C preferred stock and warrants to purchase
2,444,900 shares of our common stock. Pursuant to the note and warrant purchase
agreements executed in connection with the March Note Placement and the Series C
preferred stock purchase agreements, beginning January 1, 2001, the holders of
at least 66 2/3% of the then outstanding shares of common stock issuable under
these warrants or the Series C preferred stock, as the case may be, may notify
us that they desire to have such shares registered for sale to the public.
Promptly following receipt of such notice and after notifying all other
applicable holders of their right to participate in such offering, we will
prepare and file, and use our best efforts to prosecute to effectiveness, an
appropriate registration statement with the SEC which includes such securities.
We may delay such registration for not longer than 180 days if our board of
directors in good faith reasonably believes that the filing would materially
adversely affect certain pending or proposed offerings or certain other actions.
If less than $5.0 million of the common stock issuable under warrants or less
than $10.0 million of common stock issuable upon conversion of the Series C
preferred stock is to be sold in such offering, we will not be obligated to
register such securities. We are obligated to make such a filing with regard to
the common stock issuable under the warrants only once, and are obligated to
make such a filing with regard to the common stock issuable upon conversion of
the Series C preferred stock only one time in any twelve month period and no
more than three times in the aggregate, unless such registration statement is
not declared effective.

     Even if the holders do not exercise these demand registration rights, once
we are eligible to effect a registration of its securities on Form S-3, the
holders will have the right to request us to register such securities on Form
S-3 as long as the aggregate proposed offering price of such securities is not
less than $3.0 million. We are obligated to honor such a request only once
during a 12 month period. If such an offering is underwritten, the holders'
securities will not be included unless the holders accept the terms of the
underwriting agreement. We may delay such an S-3 offering for no longer than 180
days if our board of directors in good faith reasonably believes that the filing
would materially adversely affect certain pending or proposed offerings or other
certain actions.

     Finally, if we propose to register any of our securities in connection with
the public offering of such securities solely for cash, other than an initial
public offering or certain other types of offerings, we shall promptly give each
holder written notice of such proposed filing. Upon the timely request of each
holder, we must, subject to certain exceptions, cause such securities to be
registered.

     Expenses incurred in connection with the registration of these securities
will be borne by us and assignment of these registration rights is permitted in
certain instances. Additionally, each holder has agreed that if requested by us
or the underwriters, it will not sell any of these
                                       65
<PAGE>   68

securities until 180 days after the effective date of an underwritten public
offering of any our shares of common stock without our prior written approval or
the approval of the underwriters. If the offering is an underwritten initial
public offering, such a request will not be required and the holders of the
warrants have agreed to execute and deliver a lock-up letter to the underwriter
if requested to do so. These registration rights will terminate at the earlier
of (a) four years after we become a public company or (b) such time as the
holder is able to sell all of such holder's securities issued hereunder in a
single three-month period in compliance with Rule 144 of the Securities Act.

DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS

     We are subject to the provisions of Section 203 of the DGCL. In general,
Section 203 of the DGCL prohibits a publicly-held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. A "business combination" includes mergers, asset sales and
other transactions resulting in a financial benefit to the interested
stockholder. Subject to certain exceptions, an "interested stockholder" is a
person who, together with affiliates and associates, owns, or within three years
did own, 15% or more of the corporation's voting stock. This provision could
delay, discourage or prohibit transactions not approved in advance by the board
of directors, such as takeover attempts that might result in a premium over the
market price of the common stock.

     Our certification of incorporation and bylaws provide that any action
required or permitted to be taken by our stockholders may be taken only at a
duly called annual or special meeting of stockholders or by a written consent
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, and
that special meetings of stockholders may be called only by our Chairman of the
Board, the President, the Chief Executive Officer or the board of directors.
These provisions could have the effect of delaying until the next stockholders'
meeting stockholder actions which are favored by the holders of a majority of
our outstanding voting securities. Our certificate of incorporation also does
not allow for cumulative voting for directors or for any other purpose. Under
cumulative voting, a minority stockholder holding a sufficient percentage of a
class of shares might be able to ensure the election of one or more directors.
These and other provisions contained in our certificate of incorporation and
bylaws could delay or discourage certain types of transactions involving an
actual or potential change in control of us or our management (including
transactions in which stockholders might otherwise receive a premium for their
shares over the then current prices) and may limit the ability of stockholders
to remove then-current management or approve transactions that stockholders may
deem to be in their best interests and, therefore, could adversely affect the
price of our common stock.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is ChaseMellon
Shareholder Services, LLC.

                                       66
<PAGE>   69

                        SHARES ELIGIBLE FOR FUTURE SALE

     Prior to this offering, there has been no market for our common stock.
Future sales of substantial amounts of common stock in the public market after
this offering could cause the market price of our common stock to decline.
Furthermore, since only a limited number of shares will be available for sale
shortly after this offering because of contractual and legal restrictions on
resale, 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, we will have outstanding      shares of
common stock. Of these shares, the      shares sold in this offering (and any
shares issued upon exercise of the underwriters' over-allotment option) will be
freely tradable without restriction under the Securities Act, unless purchased
by "affiliates" of ours as that term is defined in Rule 144 under the Securities
Act. Affiliates generally include officers, directors or 10% stockholders.
Shares eligible to be sold by affiliates pursuant to Rule 144 are subject to
volume restrictions as described below.

     The remaining      shares outstanding are "restricted securities" within
the meaning of Rule 144 under the Securities Act. These shares 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 under the Securities Act, which are
summarized below. Sales of these shares in the public market, or the
availability of such shares for sale, could cause the market price of our common
stock to decline.

     Our stockholders have entered into lock-up agreements generally providing
that they will not offer, sell, contract to sell or grant any option to purchase
or otherwise dispose of our common stock or any securities exercisable for or
convertible into our common stock owned by them for a period of 180 days after
the effective date of the registration statement filed pursuant to this
offering. 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 will not be salable until such
agreements expire or are waived. Taking into account the lock-up agreements, the
following shares will be eligible for sale in the public market at the following
times:

     - Beginning on the effective date of this prospectus, only the shares sold
       in the offering will be immediately available for sale in the public
       market;

     - Beginning 180 days after the effective date, approximately      shares
       will be eligible for sale pursuant to Rules 701, 144 and 144(k), of which
       all but      shares are held by affiliates;

     - An additional      shares will be eligible for sale pursuant to Rule 701
       at various times beginning 180 days after the effective date of which all
       but      shares are held by affiliates; and

     - An additional      shares will be eligible for sale pursuant to Rule 144
       on           .

                                       67
<PAGE>   70

RULE 144

     Under Rule 144, beginning 90 days after the effective date of the
registration statement of which this prospectus is a part, a person, or persons
whose shares are aggregated, who has beneficially owned restricted shares for at
least one year, which includes the holding period of any prior owner other than
an affiliate, would generally be entitled to sell within any three-month period
a number of shares that does not exceed the greater of:

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

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

     Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
Mobility.

RULE 144(k)

     Under Rule 144(k), a person who was not an affiliate of Mobility at any
time during the 90 days preceding a sale, and who has beneficially owned the
shares proposed to be sold for at least two years, which includes the holding
period of any prior owner except an affiliate, is entitled to sell these shares
without complying with the manner of sale, public information, volume limitation
or notice provisions of Rule 144.

RULE 701

     In general, under Rule 701, any of our employees, consultants or advisors,
other than affiliates, who purchases or receives shares from us in connection
with a compensatory stock purchase plan or option plan or other written
agreement will be eligible to resell these shares beginning 90 days after the
effective date of the registration statement of which this prospectus is a part,
subject only to the manner of sale provisions of Rule 144, and by affiliates
under Rule 144 without compliance with its holding period requirements.

REGISTRATION RIGHTS

     Upon completion of this offering, the holders of 12,482,281 shares of
common stock or securities convertible into common stock will be entitled to
registration rights with respect to these shares under the Securities Act. When
these shares are registered under the Securities Act they will be freely
tradable unless held by affiliates.

STOCK OPTIONS

     In addition, we intend to file a registration statement under the
Securities Act as promptly as possible upon the completion of this offering to
register      shares of common stock to be issued pursuant to our employee
benefit plans or upon exercise of non-plan options. As a result, any options or
rights exercised under the 1996 Plan after the effectiveness of the registration
statement will be available for sale in the public market 180 days after the
effective date of this offering upon the expiration of lock-up agreements.
However, such shares held by affiliates will still be subject to the volume
limitation, manner of sale, notice and public information requirements of Rule
144 unless otherwise resalable under Rule 701.

     Subject to the terms and conditions of the underwriting agreement, the
underwriters named below, through their representatives, Deutsche Bank
Securities Inc., Banc of America Securities LLC and J.C. Bradford & Co., have
severally agreed to purchase from us the following respective numbers of shares
of common stock at a public offering price less the underwriting discounts and
commissions set forth on the cover page of this prospectus:

          Total.............................................
                                                                ===========
</TABLE>

     The underwriting agreement provides that the obligations of the
underwriters to purchase the common stock is subject to the terms and conditions
set forth in the underwriting agreement. The underwriting agreement requires the
underwriters to purchase all of the shares of the common stock offered by this
prospectus, if any are purchased. The shares of common stock offered by the
underwriters pursuant to this prospectus are subject to prior sale, when, as and
if delivered to and accepted by the underwriters, and subject to the
underwriters' right to reject any order in whole or in part.

     We have been advised by the representatives that the underwriters propose
to offer the shares of common stock to the public at the initial public offering
price of $     per share and to certain dealers at a price that represents a
concession not in excess of $     per share. Any such securities dealers may
resell any shares purchased from the underwriters to certain other brokers or
dealers at a discount of up to $0.10 per share from the public offering price.
The underwriters may change the public offering price after the common stock is
released for sale to the public.

     The underwriters may sell more shares than the total number set forth in
the table above. To cover these sales, we have granted the underwriters an
option to purchase up to an aggregate of           additional shares of common
stock at the initial public offering price, less the underwriting discounts and
commissions. The underwriters may exercise this option at any time within 30
days after the date of this prospectus only to cover these sales. To the extent
the underwriters exercise this option, each of the underwriters will purchase
shares in approximately the same proportion as the number of shares of common
stock to be purchased by it shown in the above table bears to           and we
will be obligated, pursuant to the option, to sell those shares to the
underwriters. If purchased, the underwriters will offer the additional shares on
the same terms as those on which the      shares are being offered. If the
underwriters exercise their over-allotment option in full, the total public
offering price will be $     , the total underwriting discount will be $     and
the total proceeds to us will be $     .

     Bank of America, N.A., an affiliate of Banc of America Securities LLC, is
our primary lender. We intend to use a portion of the proceeds from this
offering to repay certain amounts outstanding under our loans from Bank of
America, N.A.

     We have agreed to indemnify the underwriters with respect to certain
liabilities, including liabilities under the Securities Act.

     To facilitate the offering of the common stock, the underwriters may engage
in transactions that stabilize, maintain or otherwise affect the market price of
the common stock. Specifically, the underwriters may over-allot shares of our
common stock in connection with this offering, thereby creating a short position
in the underwriters' account. A short position

                                       69
<PAGE>   72

results when an underwriter sells more shares of common stock than such
underwriter is committed to purchase. Additionally, to cover over-allotments or
to stabilize the market price of the common stock, the underwriters may bid for,
and purchase, shares of our common stock at a level above that which might
otherwise prevail in the open market. The underwriters are not required to
engage in these activities, and, if they do, they may discontinue doing so at
any time. The underwriters also may reclaim selling concessions allowed to an
underwriter or dealer, if the underwriters repurchase shares distributed by such
underwriter or dealer. These stabilizing and other transactions may cause the
price of our common stock to be higher than it otherwise would be in the absence
of such transactions. These transactions may be effected on the Nasdaq National
Market, in the over-the-counter market or otherwise.

     We and our officers and directors and certain of our stockholders have
agreed not to offer, sell or make any other disposition of any shares of our
common stock or other securities convertible into or exchangeable or exercisable
for shares of our common stock or derivatives of our common stock for a period
of 180 days after the date of this prospectus, directly or indirectly, without
the prior written consent of Deutsche Bank Securities Inc.

     The representatives of the underwriters have advised us that the
underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.

     We estimate that the total expenses of the offering, excluding underwriting
discounts and commissions, will be approximately $          .

     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to      shares for our vendors, customers and other
third parties. The number of shares of common stock available for sale to the
general public will be reduced to the extent these reserved shares are
purchased. Any reserved shares that are not purchased will be offered by the
underwriters to the general public on the same basis as the other shares offered
by this prospectus.

     We have filed an application for our common stock to be quoted on the
Nasdaq National Market under the symbol "MOBE".

PRICING OF THIS OFFERING

     Prior to this offering, there has been no public market for our common
stock. Consequently, the initial public offering price for our common stock was
determined by negotiation among us and the representatives of the underwriters.
Among the factors considered in determining the public offering price were:

     - prevailing market conditions;

     - our results of operations in recent periods;

     - the present stage of our development;

     - the market capitalizations and stages of development of other companies
       which we and the representatives of the underwriters believe to be
       comparable to us; and

     - estimates of our business potential.

                                    EXPERTS

     Our consolidated financial statements as of December 31, 1997 and 1998 and
for each of the years in the three-year period ended December 31, 1998, have
been included herein and in the registration statement filed in connection with
this offering in reliance upon the report of KPMG LLP, independent certified
public accountants, appearing elsewhere herein and upon the authority of said
firm as experts in accounting and auditing. The report of KPMG LLP covering the
December 31, 1997 and 1998 consolidated financial statements contains an
explanatory paragraph that states that our recurring losses from operations and
net capital deficiency raise substantial doubt about our ability to continue as
a going concern. The consolidated financial statements do not include any
adjustments that might result from the outcome of that uncertainty.

                    ADDITIONAL INFORMATION AVAILABLE TO YOU

     We have filed with the SEC a registration statement on Form S-1 with
respect to the common stock in this offering. This prospectus, which constitutes

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors of
Mobility Electronics, Inc.:

     We have audited the accompanying consolidated balance sheets of Mobility
Electronics, Inc. and subsidiaries as of December 31, 1997 and 1998, and the
related consolidated statements of operations, stockholders' deficiency and
comprehensive income (loss) and cash flows for each of the years in the
three-year period ended December 31, 1998. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

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

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Mobility
Electronics, Inc. and subsidiaries as of December 31, 1997 and 1998, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1998, in conformity with generally accepted
accounting principles.

     The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in note
2 to the consolidated financial statements, the Company has a stockholders'
deficiency, a working capital deficiency and has suffered significant recurring
losses from operations. These matters raise substantial doubt about its ability
to continue as a going concern. Management's plans in regard to these matters
are also described in note 2. The consolidated financial statements do not
include any adjustments that might result from this uncertainty.

                  MOBILITY ELECTRONICS, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
          DECEMBER 31, 1996, 1997, AND 1998 AND THE NINE MONTHS ENDED
              SEPTEMBER 30, 1998 (UNAUDITED) AND 1999 (UNAUDITED)

(1) NATURE OF BUSINESS

     Mobility Electronics, Inc. (Mobility or the Company) formerly known as
Electronics Accessory Specialists International, Inc. was formed on May 4, 1995.
Mobility was originally formed as a limited liability corporation, however, in
August 1996 the Company became a C Corporation incorporated in the State of
Delaware.

     Mobility designs, develops and markets connectivity and remote PCI bus
technology and products for the computer industry and a broad range of related
embedded processor applications. In addition, Mobility manufactures and/or
distributes in-car and in-air DC power adapters, portable computer docking
stations, port replicators, and monitor stands. Mobility distributes products in
the United States, Canada and Europe.

(2) LIQUIDITY

     The Company's consolidated financial statements have been presented on the
basis that it is a going concern, which contemplates the realization of assets
and the satisfaction of liabilities in the normal course of business. The
Company has an accumulated deficit from operations of $30,202,415 as of December
31, 1998, has a working capital deficiency of $3,189,758 as of December 31, 1998
and has generated significant losses from operations since inception. The
Company's business plan calls for an equity investment from a Private Placement
and extension of its line of credit and long-term debt, which management
believes will be adequate to provide the Company with operating cash flow to
meet its current obligations. However, there is no certainty that the Company's
plan will be successfully carried out. The consolidated financial statements do
not include any adjustments that might result from the outcome of this
uncertainty.

(3) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  (a) 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 amount of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates. Material
estimates that are particularly susceptible to significant change include
valuation of accounts receivable and inventories, impairment of intangible
assets and valuation of deferred tax assets. Management believes that such
estimates have been appropriately established in accordance with generally
accepted accounting principles.

  (b) Principles of Consolidation

     The consolidated financial statements include the accounts of Mobility and
its subsidiaries. All significant intercompany balances and transactions have
been eliminated in consolidation.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  (c) Cash and Cash Equivalents

     All short-term investments purchased with an original maturity of three
months or less are considered to be cash equivalents. Cash and cash equivalents
include cash on hand and amounts on deposit with financial institutions.

  (d) Inventories

     Inventories consist of component parts purchased partially and fully
assembled for computer accessory items. Inventories are stated at the lower of
cost (first-in, first-out method) or market.

  (e) Property and Equipment

     Property and equipment are stated at cost. Equipment held under capital
leases is stated at the present value of future minimum lease payments.
Depreciation on furniture, fixtures and equipment is provided using the
straight-line method over the estimated useful lives of the assets ranging from
two to seven years. Tooling is capitalized at cost and is depreciated over a
two-year period. Equipment held under capital leases and leasehold improvements
are amortized over the shorter of the lease term or estimated useful lives of
the assets.

  (f) Deferred Loan Costs

     Deferred loan costs are amortized over the term of the related debt.

  (g) Licensing Fees and Noncompete Agreement

     The cost of licensing fees and a noncompete agreement are included in other
assets and amortized on a straight-line basis over their estimated economic
lives of two to five years.

  (h) Goodwill

     Goodwill, which is included in other assets, represents the excess of
purchase price over fair value of net assets acquired, is amortized on a
straight-line basis over five years. The Company assesses the recoverability of
this intangible asset by determining whether the amortization of goodwill
balance over its remaining life can be recovered through undiscounted future
operating cash flows of the acquired operation. The assessment of the
recoverability of goodwill will be impacted if estimated future operating cash
flows are not achieved.

  (i) Impairment of Long-Lived Assets

     The Company reviews long-lived assets and certain identifiable intangibles
for impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to future undiscounted net cash flows expected to be generated by the asset. If
such assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets exceed the
fair value of the assets. Assets to be disposed of are reported at the lower of
the carrying amount or fair value less costs to sell.

  (j) Revenue Recognition

     Revenue from product sales is recognized upon shipment to the customer.
Provisions for returns and credits are provided for in the same period the
related sales are recorded.

  (k) Warranty Reserve

     The Company provides limited warranties on certain of its products for
periods generally not exceeding three years. The Company accrues warranty costs
for potential product liability and warranty claims based on the Company's claim
experience. The Company's warranty accrual was $0, $50,000, $174,071 and
$264,071 (unaudited) as of December 31, 1996, 1997, 1998 and September 30, 1999,
respectively.

  (l) Income Taxes

     The Company utilizes the asset and liability method of accounting for
income taxes. Under the asset and liability method, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases. Deferred tax assets and
liabilities are measured using enacted tax rates expected to apply to taxable
income in the year in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

  (m) Net Loss Per Common Share

     Basic loss per share is computed by dividing loss available to common
stockholders by the weighted-average number of common shares outstanding for the
period. Diluted loss per share reflects the potential dilution that could occur
if securities or contracts to issue common stock were exercised or converted to
common stock or resulted in the issuance of common stock that then shared in the
earnings or loss of the Company. Nominal issuances of stock options and warrants
for all periods have been included in the calculations of diluted net loss per
common share in accordance with Staff Accounting Bulletin No. 98.

  (n) Employee Stock Options

     The Company has elected to follow Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees (APB 25) and related
interpretations in accounting for its employee stock options and to adopt the
"disclosure only" alternative treatment under Statement of Financial Accounting
Standards No. 123, Accounting for Stock-Based Compensation (SFAS 123). SFAS 123
requires the use of fair value option valuation models that were not developed
for use in valuing employee stock options. Under SFAS No. 123, deferred
compensation is recorded for the excess of the fair value of the stock on the
date of the option grant, over the exercise price of the option. The deferred
compensation is amortized over the vesting period of the option.

  (o) Fair Value of Financial Instruments

     The fair value of accounts receivable, accounts payable, and accrued
expenses approximates the carrying value due to the short-term nature of these
instruments. Management has estimated that the fair values of the line of credit
and notes payable approximate the current balances outstanding, based on
currently available rates for debt with similar terms.

  (p) Research and Development

     The cost of research and development is charged to expense as incurred.

  (q) Segment Reporting

     The Company has only one operating business segment, the sale of peripheral
computer equipment.

  (r) Comprehensive Loss

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, Reporting Comprehensive Income (SFAS No.
130) which became effective for the Company January 1, 1998. SFAS No. 130
established standards for reporting and displaying comprehensive income and its
components in a full set of general-purpose financial statements. The Company
adopted the provisions of SFAS No. 130 in 1998. Financial statements presented
for earlier periods have been reclassified in accordance with the requirements
of SFAS No. 130.

  (s) Unaudited Interim Financial Information

     The unaudited interim financial statements as of September 30, 1999 and for
the nine months ended September 30, 1998 and 1999, reflect, in the opinion of
management, all adjustments (which include only normal recurring adjustments)
necessary to fairly present the financial position, results of operations, and
cash flows as of and for the periods presented. The results of the interim
periods presented are not necessarily indicative of results to be expected for
the full year.

$2,852,054 and then replaced by a promissory note in the face amount of
$3,000,000. The interest rate on amounts borrowed under this promissory note is
2.5% plus the bank's corporate base rate per annum, payable monthly and
remaining principal and interest due March 31, 2000. In addition, the bank
issued new promissory notes with face values of $1,500,000, $150,000 and $75,000
with interest rate on amounts borrowed under these promissory notes ranging from

(9) CAPITAL LEASE OBLIGATIONS

     The Company is obligated under various capital leases primarily for
computer equipment and office furniture that expire at various dates through
2001. These leases meet the various criteria of capital leases and are,
therefore, classified as capital lease obligations. Capital lease obligations
reflect the present value of future rental payments, discounted at the interest
rate implicit in each of the leases. A summary of the future minimum lease
payments required under the capital leases as of December 31, 1998 follows:

</TABLE>

     The valuation allowance for deferred tax assets as of December 31, 1997 and
1998 was $3,841,000 and $10,610,007, respectively. The net change in the total
valuation allowance for the years ended December 31, 1997 and 1998 was an
increase of $2,998,000 and $6,769,007, respectively. In assessing the
realizability of deferred tax assets, management considers whether it is more
likely than not that some portion or all of the deferred tax assets will not be
realized. The ultimate realization of deferred tax assets is dependent upon
generation of future taxable income during the periods in which those temporary
differences become deductible. In addition, due to the frequency of equity
transactions within the Company, it is possible the use of the net operating
loss carryforward may be limited in accordance with Section 382 of the Internal
Revenue Code. A determination as to this limitation will be made at a future
date as the net operating losses are utilized. Management considers the
scheduled reversal of deferred tax liabilities, projected future taxable income,
and tax planning strategies in making this assessment. Based upon the level of
historical taxable income and projections for future taxable income over the
periods in which the deferred tax assets are deductible, management believes it
is more likely than not that the Company will not realize the benefits of these
deductible differences.

(14) CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

     Financial instruments that potentially subject the Company to
concentrations of credit risk consist principally of cash and trade accounts
receivable. The Company places its cash with high credit quality financial
institutions and generally limits the amount of credit exposure to the amount of
FDIC coverage. However, periodically during the year, the Company maintains cash
in financial institutions in excess of the FDIC insurance coverage limit of
$100,000. The Company performs ongoing credit evaluations of its customers'
financial condition but does not typically require collateral to support
customer receivables. The Company establishes an

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

allowance for doubtful accounts based upon factors surrounding the credit risk
of specific customers, historical trends and other information.

     During 1996, the Company had an agreement with Extend Microproducts, Inc.
(Xtend) to market and distribute the Company's products in the United States.
During 1996, the Company sold a substantial portion (approximately 53%) of its
products through Xtend. In September 1996, the distribution agreement with Xtend
was terminated. The Company has expanded its U.S. distribution network and is
building a United States sales team to directly serve U.S. customers. This
termination has diversified the Company's customer base and reduced their credit
risk.

     Two customers accounted for 29% and 18% of net sales for the year ended
December 31, 1997. Three customers accounted for 18%, 17% and 16% of net sales
for the year ended December 31, 1998. Two customers accounted for 25% and 10%
(unaudited) of net sales for the nine months ended September 30, 1999.

(15) RELATED PARTY TRANSACTIONS

     During 1996, the Company had an agreement with Xtend to market and
distribute the Company's products. Xtend held an ownership interest in the
Company. In September 1996, that agreement was terminated and the Company
repurchased a portion, 308,308 shares of common stock, of Xtend's ownership
interest of $510,000 for forgiveness of outstanding trade receivables of
$510,000.

     The Company has an agreement with a related entity under which this entity
provides management services. The Company paid the consultant approximately
$5,000, $32,000 and $52,000 for the years ended December 31, 1996, 1997 and
1998, respectively, and approximately $27,000 (unaudited) for the nine months
ended September 30, 1999.

(16) EXPORT SALES

     Export sales were approximately 31% and 34% of the Company's net sales for
the years ended December 31, 1997 and 1998, respectively, and 19% (unaudited) of
the Company's net sales for the nine months ended September 30, 1999. The
principal international market served by the Company was Europe.

(17) CONTINGENCIES AND LITIGATION

     The Company is involved in various claims and legal actions arising in the
ordinary course of business. In the opinion of management, based on consultation
with legal counsel, the ultimate disposition of these matters will not have a
material adverse effect on the Company's financial position, results of
operations or liquidity. Accordingly, the accompanying consolidated financial
statements do not include a provision for losses, if any, that might result from
the ultimate disposition of these matters.

(18) YEAR 2000 ISSUE

     In 1998, the Company developed a plan to deal with the Year 2000 related
issues and began modifying and/or converting its computer systems to be Year
2000 compliant. The plan provides for the modification and conversion efforts to
be completed by December 31, 1999. The Year 2000 issue is the result of computer
programs being written using two digits rather than four to define the
applicable year. Management is in the process of assessing Year 2000 remediation
efforts of the Company's significant suppliers. Although management believes its
                                      F-21

efforts minimize the potential adverse effects on the Company, there can be no
absolute assurance that all its suppliers will become Year 2000 compliant on
time or in a way that will be compatible with the Company's systems. The Company
will evaluate appropriate courses of action, including replacement of certain
systems whose associated costs would be recorded as assets and subsequently
amortized, or modification of its existing systems which costs would be expensed
as incurred. The Company does not believe expenditures to be Year 2000 compliant
have been material. However, there can be no assurance that the Company will be
able to completely resolve all Year 2000 issues or that the ultimate cost to
identify and implement solutions to all Year 2000 issues will not be material to
the Company.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

DELAWARE GENERAL CORPORATION LAW

     Section 145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

     Section 145(b) of the DGCL states that a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation, and except that no
indemnification shall be made in respect of any claim, issue or matter as to

                                      II-1
<PAGE>   103

which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.

     Section 145(c) of the DGCL provides that to the extent that a present or
former director or officer of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in defense of any claim, issue or
matter therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith.

     Section 145(d) of the DGCL states that any indemnification under
subsections (a) and (b) of Section 145 (unless ordered by a court) shall be made
by the corporation only as authorized in the specific case upon a determination
that indemnification of the present or former director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in subsections (a) and (b). Such determination shall be
made, with respect to a person who is a director or officer at the time of such
determination, (1) by a majority vote of the directors who are not parties to
such action, suit or proceeding, even though less than a quorum, or (2) by a
committee of such directors designated by a majority vote of such directors,
even though less than a quorum, or (3) if there are no such directors, or if
such directors so direct, by independent legal counsel in a written opinion, or
(4) by the stockholders.

     Section 145(e) of the DGCL provides that expenses (including attorneys'
fees) incurred by an officer or director in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director or
officer to repay such amount if it shall ultimately be determined that such
person is not entitled to be indemnified by the corporation as authorized in
Section 145. Such expenses (including attorneys' fees) incurred by former
directors and officers or other employees and agents may be so paid upon such
terms and conditions, if any, as the corporation deems appropriate.

     Section 145(f) of the DGCL states that the indemnification and advancement
of expenses provided by, or granted pursuant to, the other subsections of
Section 145 shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors or otherwise,
both as to action in such person's official capacity and as to action in another
capacity while holding such office.

     Section 145(g) of the DGCL provides that a corporation shall have the power
to purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against such person and incurred by such person
in any such capacity, or arising out of such person's status as such, whether or
not the corporation would have the power to indemnify such person against such
liability under Section 145.

     Section 145(j) of the DGCL states that the indemnification and advancement
of expenses provided by, or granted pursuant to, Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent, and shall inure to the
benefit of the heirs, executors and administrators of such a person.

CERTIFICATE OF INCORPORATION

     The Certificate of Incorporation of the Company provides that a director of
the Company shall not be personally liable to the Company or its stockholders
for monetary damages for breach of fiduciary duty as a director, except as
limited by the DGCL. If the DGCL is amended to authorize the further elimination
or limitation of the liability of directors, then the liability of a director of
the Company, in addition to the limitation on personal liability described
above, shall be limited to the fullest extent permitted by the amended DGCL.
Further, any repeal or modification of such provision of the Certificate of
Incorporation by the stockholders of the Company shall be prospective only, and
shall not adversely affect any limitation on the personal liability of a
director of the Company existing at the time of such repeal or modification.

BYLAWS

     The Bylaws of the Company provide that the Company (i) shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by reason of the fact that such
person is or was a director or officer of the Company, or is or was serving at
the request of the Company as a director or officer of another corporation,
partnership, joint venture, trust, other enterprises or employee benefit plan
and (ii) upon a determination by the Board of Directors that indemnification is
appropriate, the Company may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by reason of the fact that such person is or was an employee or agent of
the Company or at the request of the Company was serving as an employee or agent
of any other corporation, partnership, joint venture, trust, other enterprise or
employee benefit plan, in the case of (i) and (ii) against reasonable expenses
(including attorneys' fees), judgments, fines, penalties, amounts paid in
settlement and other liabilities actually and reasonably incurred by such person
in connection with such action or suit if such person acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that his conduct was unlawful. However, in an action
or suit by or in the right of the Company to procure a judgment in its favor, no
indemnification shall be made in respect of any claim as to which such person
shall have been adjudged to be liable to the Company unless and only to the
extent that a court of appropriate jurisdiction shall determine that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity of such expenses
which the court shall deem proper. Any indemnification shall be made by the
Company upon a determination that indemnification of such person is proper in
the circumstances because he has met the applicable standard of conduct set
forth above. Expenses incurred by a person who is or was a director or officer
of the Company in defending such actions or suits shall be paid by the Company
at reasonable intervals in advance of the final disposition of such action or
suit upon receipt of an undertaking by or on behalf of the director or officer
to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the Company. In addition, the Company shall pay or
reimburse expenses incurred by any person who is or was a director or officer of
the Company in connection with such person's appearance as a witness or other
participant in a proceeding in which such person or the Company is not a named
party to such proceeding, provided that such appearance or participation is on
behalf of the Company or by reason of his past or present capacity as a director
or officer of the Company. The Company intends these provisions to provide
indemnification for appropriate persons to the fullest extent permitted by law.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

     The Company has issued unregistered securities to (a) founders and
employees and (b) other individual and institutional investors. Each such
issuance was made in reliance upon the exemptions from registration requirements
of the Securities Act of 1933, as amended, contained in Section 4(2) and/or
Regulation D promulgated thereunder, or Rule 701 promulgated thereunder on the
basis that such transactions did not involve a public offering. When
appropriate, the Company determined that the purchasers of securities described
below were sophisticated investors who had the financial ability to assume the
risk of their investment in the Company's securities and acquired such
securities for their own account and not with a view to any distribution thereof
to the public. The certificates evidencing the securities bear legends stating
that the securities are not to be offered, sold or transferred other than
pursuant to an effective registration statement under the Securities Act or an
exemption from such registration requirements. The following information relates
to securities issued or sold by the Company within the last twelve quarters:

ITEM 17. UNDERTAKINGS.

     The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 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 Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     The undersigned registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, 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.

                                      II-10
<PAGE>   112

          (2) For the purpose of determining any liability under the Securities
     Act of 1933, 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.

         (l) "Unrecovered Initial Series B Capital Contribution" shall mean the

less (ii) the cumulative sum of money and the net market value of any other

to Section 4.C.(2)(a) below.

         (2) Dividends and Distributions.

                  (a) Regular Dividends. Each holder of shares of Series A
Preferred shall be entitled to receive dividends at a rate of ten percent (10%)
per annum on the average daily balance of its Unrecovered Initial Series A
Capital Contribution, which shall be fully cumulative. The dividends payable
hereunder shall be payable to holders of record as they appear on the stock
books of the Corporation on the applicable record date, which shall be not more
than 60 nor less than 10 days preceding the payment date for such dividends, as
fixed by the Board of Directors. The foregoing dividends on the Series A
Preferred shall accrue from the date of issuance of each share, but shall be
payable only when, as and if declared by the Board of Directors out of funds
legally available therefor. The dividends shall be payable in cash. The amount
of dividends payable shall be computed on the basis of a 360-day year of twelve
30-day months. All accrued but unpaid dividends shall continue to accrue
interest at the above rate from each dividend date until paid. Except as
provided in Section 2(b) below, the Corporation may not pay any dividend or make
any distribution to the holders of Series B Preferred or Common Stock until the
holders of Series A Preferred have received an amount equal to: (i) all
dividends payable to such holders under this Section 2(a); and (ii) their
Unrecovered Initial Series A Capital Contributions (collectively, the "Series A
Preferred Return"). Once the holders of Series A Preferred have received their
Series A Preferred Return, then the 10% dividend provided for in this Section
2(a) shall cease.

                  (b) Other Permitted Dividends. Notwithstanding Section 2(a)
hereof, the Corporation may at any time, out of funds legally available
therefor, repurchase shares of Common Stock (i) issued to or held by employees,
directors or consultants of the Corporation or its subsidiaries upon termination
of their employment or services, pursuant to any agreement providing for such
right of repurchase, or (ii) issued to or held by any person subject to the
Corporation's right of first refusal to purchase such shares where the purchase
is pursuant to the exercise of such right of first refusal, in either case
whether or not dividends on the Series A Preferred shall have been declared and
paid or funds set aside therefor, subject to any other contractual restrictions
entered into by the Corporation.

         (3) Liquidation Rights. In the event of any Liquidation, distributions
shall be made to the holders of Series A Preferred in respect of such Series A
Preferred before any amount shall be paid to the holders of any other class or
series of capital stock of the Corporation in the following manner:

                  (a) Series A Preferred. The holders of Series A Preferred
shall be entitled to be paid first out of the assets of the corporation
available for distribution to holders of its capital stock an amount per share
equal to each holder of Series A Preferred's Unrecovered



                                      -3-
<PAGE>   4

Initial Series A Capital Contribution, plus any accrued but unpaid dividends. If
the proceeds from a Liquidation are not sufficient to pay to the holders of
Series A Preferred the preference amount set forth above, then such holders
shall instead be entitled to receive the entire assets and funds of the
Corporation legally available for distribution to the holders of capital stock,
which assets and funds shall be distributed ratably among the holders of the
Series A Preferred.

         (b) Events Deemed a Liquidation. For purposes of this Section 3, the
holders of a majority of the Series A Preferred may, by written notice to the
Corporation, elect to have treated as a Liquidation the consolidation or merger
of the Corporation with or into any other corporation or legal entity or the
sale or other transfer in a single transaction or a series of related
transactions of all or substantially all of the assets of the Corporation, or
any other reorganization of the Corporation, unless the stockholders of the
Corporation immediately prior to any such transaction are holders of a majority
of the voting securities of the surviving or acquiring corporation immediately
thereafter (and for purposes of this calculation, equity securities which any
stockholder of the Corporation owned immediately prior to such merger or
consolidation as a stockholder of another party to the transaction shall be
disregarded).

                  (c) Valuation of Securities and Property. In the event the
Corporation proposes to distribute assets other than cash in connection with any
Liquidation, the value of the assets to be distributed to the holders of shares
of Series A Preferred shall be determined in good faith by the Board of
Directors. Any securities not subject to an investment letter or similar
restrictions on free marketability shall be valued as follows:

                           (i) if traded on a national securities exchange or
         the Nasdaq National Market ("Nasdaq"), the value shall be deemed to be
         the average of the security's closing prices on such exchange or Nasdaq
         over the thirty (30) trading-day period ending three (3) days prior to
         the distribution;

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

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

The method of valuation of securities subject to an investment letter or other
restrictions on free marketability shall be adjusted to make an appropriate
discount from the market value determined as above in clauses (i), (ii) or (iii)
to reflect the fair market value thereof as determined in good faith by the
Board of Directors. The holders of more than 50% of the outstanding shares of
Series A Preferred shall have the right to challenge any determination by the
Board of Directors of fair market value pursuant to this Section 3(c), in which
case the determination of fair value shall be made by an independent appraiser
selected jointly by the Board of Directors and the challenging parties, the cost
of such appraisal to be borne equally by the Corporation and the challenging
parties.

         (4) Redemption.

                  (a) The Series A Preferred shall be redeemable, in whole or in
part, out of legally available funds, at the option of the Corporation, at any
time upon giving notice as provided in (b) below, at a redemption price equal to
the Series A Preferred Return of the Series A Preferred up to the Series A
Redemption Date (as defined below).

                  (b) At least 30 days but not more than 60 days prior to the
date fixed for the redemption of shares of Series A Preferred pursuant to (a)
above (the "Series A Redemption Date"), written notice of such redemption shall
be mailed to each holder of record of shares of Series A Preferred to be
redeemed in a postage prepaid envelope addressed to such holder at his post
office address as shown on the records of the Corporation; provided, however,
that no defect in such notice shall affect the validity of the proceeding for
the redemption of the shares of Series A Preferred to be redeemed. Each such
notice shall state: (i) the Series A Redemption Date; (ii) the number of shares
of Series A Preferred to be redeemed and, if less than all the shares held by
such holder are to be redeemed from such holder, the number of shares to be
redeemed from such holder or their method of calculating such number; (iii) the
cash redemption price; and (iv) the place or places where certificates for such
shares are to be surrendered for payment of the redemption price. On or after
the Series A Redemption Date, each holder of shares of Series A Preferred to be
redeemed shall present and surrender his certificate or certificates for such
shares to the Corporation at the place designated in such notice and thereupon
the redemption price of such shares shall be paid to or on the order of the
person whose name appears on such certificate or certificates as the owner
thereof and each surrendered certificate shall be cancelled. In case less than
all the shares represented by such certificate are redeemed, a new certificate
shall be issued representing the unredeemed shares. From and after the Series A
Redemption Date (unless default shall be made by the Corporation in payment of
the redemption price) all rights to dividends on the shares of Series A
Preferred designated for redemption in such notice shall cease and all rights of
the holders thereof as stockholders of the Corporation, except the right to
receive the redemption price thereof (including all declared and unpaid
dividends up to the Series A Redemption Date), without interest, upon the
surrender of certificates representing the same, shall cease and terminate and
such shares shall not thereafter be transferred (except with the consent of the
Corporation) on the books of the Corporation and such shares shall not be deemed
to be outstanding for any purpose whatsoever.

                  (c) If less than all of the shares of Series A Preferred are
to be redeemed, the Board of Directors shall allocate the aggregate Series A
Preferred Return of shares to be redeemed pro rata (or as nearly pro rata as
practicable), by lot, or by any other method that complies with the requirements
of the principal national securities exchange, if any, on which the shares being
redeemed are listed, at the direction of the Board of Directors. Regardless of
the method used, the calculation of the number of shares to be redeemed shall be
based upon whole shares, such that the Corporation shall in no event be required
to issue fractional shares of Series A Preferred or cash in lieu thereof. In the
event a method required proration is used, shares shall be rounded downward to
the nearest whole number of shares.

                  (d) Notwithstanding the above, to the extent the Corporation
has legally available funds, the Corporation shall redeem the Series A Preferred
at the following times and in the following amounts: (i) upon the occurrence of
a Sales Transaction, Distributable Cash in the amount necessary to cause each
holder of Series A Preferred to receive its Series A Preferred Return shall be
distributed to the holders of Series A Preferred; (ii) within 45 days after the
end of each calendar quarter and until each holder of Series A Preferred has
received its Series A Preferred Return, the Corporation shall distribute an
amount of Distributable Cash to the holders of Series A Preferred equal to at
least 25% of the Corporation's net operating cash flow for the perceeding
quarter (provided that, to the extent such funds are necessary for the
Corporation's operations, any such quarterly distribution may be waived by the
vote of at least five (5) directors of the Corporation); and (iii) at such other
times and in such amounts as the Board of Directors of the Corporation, in its
sole discretion, may determine.

         (5) Voting Rights. Except as otherwise required by law or by Section 8
below, the holder of each share of Series A Preferred will not be entitled to
vote on any matters.

         (6) Notices of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or other distribution, any right to subscribe for, purchase or
otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right, the Corporation shall mail to each
holder of Series A Preferred, at least ten (10) days prior to the date specified
therein, a notice specifying the date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and the amount and
character of such dividend, distribution or right.

         (7) Notices. Any notice required by the provisions of this Certificate
of Incorporation to be given to the holders of Series A Preferred shall be
deemed given when deposited in the United States mail, postage prepaid, and
addressed to each holder of record at such holder's address appearing on the
books of the Corporation.

         (8) Approval of Certain Transactions While Any Series A Preferred is
Outstanding. So long as any shares of Series A Preferred are outstanding, the
Corporation shall not, without first obtaining the approval of the holders of at
least a majority of the shares of Series A Preferred then outstanding, voting as
a separate class, take any action that:

                  (a) alters the rights, preferences or privileges of the Series
A Preferred;

                  (b) creates any new class or series of shares that has a
preference over or is on a parity with the Series A Preferred with respect to
dividends or liquidation preferences;

                  (c) reclassifies or amends the term of any capital stock into
shares having a preference over or parity with the Series A Preferred with
respect to dividends or liquidation preferences; or



                                      -6-
<PAGE>   7

                  (d) repurchases, redeems or retires any shares of capital
stock of the Corporation other than as permitted in Section 2(b) above.

         4.C. Series B Preferred Stock. The Corporation is authorized to issue
4,186 shares of "Series B Preferred Stock" (the "Series B Preferred"). The
preferences, voting powers, qualifications, special or relative rights or
privileges of the shares of Series B Preferred are as follows:

         (1) Definitions. Terms defined in Article 4.B. Section 1 above shall
have the same meaning in this Article 4.C.

         (2) Dividends and Distributions.

                  (a) Regular Dividends. Each holder of shares of Series B
Preferred shall be entitled to receive dividends at a rate of eight percent (8%)
per annum on the average daily balance of its Unrecovered Initial Series B
Capital Contribution, which shall be fully cumulative. The dividends payable
hereunder shall be payable to holders of record as they appear on the stock
books of the Corporation on the applicable record date, which shall be not more
than 60 nor less than 10 days preceding the payment date for such dividends, as
fixed by the Board of Directors. The foregoing dividends on the Series B
Preferred shall accrue from the date of issuance of each share, but shall be
payable only when, as and if declared by the Board of Directors out of funds
legally available therefor. The dividends shall be payable in cash. The amount
of dividends payable shall be computed on the basis of a 360-day year of twelve
30-day months. All accrued but unpaid dividends shall continue to accrue
interest at the above rate from each dividend date until paid. Except as
provided in Section 2(b) below, the Corporation may not pay any dividend or make
any distribution to the holders of Common Stock until the holders of Series B
Preferred have received an amount equal to: (i) all dividends payable to such
holders under this Section 2(a); and (ii) their Unrecovered Initial Series B
Capital Contributions (collectively, the "Series B Preferred Return"). Once the
holders of Series B Preferred have received their Series B Preferred Return,
then the 8% dividend provided for in this Section 2(a) shall cease.

                  (b) Other Permitted Dividends. Notwithstanding Section 2(a)
hereof, the Corporation may at any time, out of funds legally available
therefor, repurchase shares of Common Stock (i) issued to or held by employees,
directors or consultants of the Corporation or its subsidiaries upon termination
of their employment or services, pursuant to any agreement providing for such
right of repurchase, or (ii) issued to or held by any person subject to the
Corporation's right of first refusal to purchase such shares where the purchase
is pursuant to the exercise of such right of first refusal, in either case
whether or not dividends on the Series B Preferred shall have been declared and
paid or funds set aside therefor, subject to any other contractual restrictions
entered into by the Corporation.

         (3) Liquidation Rights. In the event of any Liquidation, distributions
shall be made to the holders of Series B Preferred in respect of such Series B
Preferred after all amounts due



                                      -7-
<PAGE>   8

pursuant to Article 4.B. are paid to holders of Series A Preferred but before
any amount shall be paid to the holders of any other class or series of capital
stock of the Corporation in the following manner:

                  (a) Series B Preferred. The holders of Series B Preferred
shall be entitled to be paid out of the assets of the Corporation available for
distribution to holders of its capital stock an amount per share equal to each
holder of Series B Preferred's Unrecovered Initial Series B Capital
Contribution, plus any accrued but unpaid dividends. If the proceeds from a
Liquidation are not sufficient to pay to the holders of Series B Preferred the
preference amount set forth above, then such holders shall instead be entitled
to receive the entire assets and funds of the Corporation legally available for
distribution to the holders of capital stock, which assets and funds shall be
distributed ratably among the holders of the Series B Preferred.

                  (b) Events Deemed a Liquidation. For purposes of this Section
3, the holders of a majority of the Series B Preferred may, by written notice to
the Corporation, elect to have treated as a Liquidation the consolidation or
merger of the Corporation with or into any other corporation or legal entity or
the sale or other transfer in a single transaction or a series of related
transactions of all or substantially all of the assets of the Corporation, or
any other reorganization of the Corporation, unless the stockholders of the
Corporation immediately prior to any such transaction are holders of a majority
of the voting securities of the surviving or acquiring corporation immediately
thereafter (and for purposes of this calculation, equity securities which any
stockholder of the Corporation owned immediately prior to such merger or
consolidation as a stockholder of another party to the transaction shall be
disregarded).

                  (c) Valuation of Securities and Property. In the event the
Corporation proposes to distribute assets other than cash in connection with any
Liquidation, the value of the assets to be distributed to the holders of shares
of Series B Preferred shall be determined in good faith by the Board of
Directors. Any securities not subject to an investment letter or similar
restrictions on free marketability shall be valued as follows:

                           (i) if traded on a national securities exchange or
         the Nasdaq National Market ("Nasdaq"), the value shall be deemed to be
         the average of the security's closing prices on such exchange or Nasdaq
         over the thirty (30) trading-day period ending three (3) days prior to
         the distribution;

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

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

The method of valuation of securities subject to an investment letter or other
restrictions on free marketability shall be adjusted to make an appropriate
discount from the market value



                                      -8-
<PAGE>   9

determined as above in clauses (i), (ii) or (iii) to reflect the fair market
value thereof as determined in good faith by the Board of Directors. The holders
of more than 50% of the outstanding shares of Series B Preferred shall have the
right to challenge any determination by the Board of Directors of fair market
value pursuant to this Section 3(c), in which case the determination of fair
value shall be made by an independent appraiser selected jointly by the Board of
Directors and the challenging parties, the cost of such appraisal to be borne
equally by the Corporation and the challenging parties.

         (4) Redemption.

                  (a) After the full payment of the Series A Preferred Return,
the Series B Preferred shall be redeemable, in whole or in part, out of legally
available funds, at the option of the Corporation, at any time upon giving
notice as provided in (b) below, at a redemption price equal to the Series B
Preferred Return of the Series B Preferred up to the Series B Redemption Date
(as defined below).

                  (b) At least 30 days but not more than 60 days prior to the
date fixed for the redemption of shares of Series B Preferred pursuant to (a)
above (the "Series B Redemption Date"), written notice of such redemption shall
be mailed to each holder of record of shares of Series B Preferred to be
redeemed in a postage prepaid envelope addressed to such holder at his post
office address as shown on the records of the Corporation; provided, however,
that no defect in such notice shall affect the validity of the proceeding for
the redemption of the shares of Series B Preferred to be redeemed. Each such
notice shall state: (i) the Series B Redemption Date; (ii) the number of shares
of Series B Preferred to be redeemed and, if less than all the shares held by
such holder are to be redeemed from such holder, the number of shares to be
redeemed from such holder or their method of calculating such number; (iii) the
cash redemption price; and (iv) the place or places where certificates for such
shares are to be surrendered for payment of the redemption price. On or after
the Series B Redemption Date, each holder of shares of Series B Preferred to be
redeemed shall present and surrender his certificate or certificates for such
shares to the Corporation at the place designated in such notice and thereupon
the redemption price of such shares shall be paid to or on the order of the
person whose name appears on such certificate or certificates as the owner
thereof and each surrendered certificate shall be cancelled. In case less than
all the shares represented by such certificate are redeemed, a new certificate
shall be issued representing the unredeemed shares. From and after the Series B
Redemption Date (unless default shall be made by the Corporation in payment of
the redemption price) all rights to dividends on the shares of Series B
Preferred designated for redemption in such notice shall cease and all rights of
the holders thereof as stockholders of the Corporation, except the right to
receive the redemption price thereof (including all declared and unpaid
dividends up to the Series B Redemption Date), without interest, upon the
surrender of certificates representing the same, shall cease and terminate and
such shares shall not thereafter be transferred (except with the consent of the
Corporation) on the books of the Corporation and such shares shall not be deemed
to be outstanding for any purpose whatsoever.

<PAGE>   10

                  (c) If less than all of the shares of Series B Preferred are
to be redeemed, the Board of Directors shall allocate the aggregate Series B
Preferred Return of shares to be redeemed pro rata (or as nearly pro rata as
practicable), by lot, or by any other method that complies with the requirements
of the principal national securities exchange, if any, on which the shares being
redeemed are listed, at the direction of the Board of Directors. regardless of
the method used, the calculation of the number of shares to be redeemed shall be
based upon whole shares, such that the Corporation shall in no event be required
to issue fractional shares of Series B Preferred or cash in lieu thereof. In the
event a method required proration is used, shares shall be rounded downward to
the nearest whole number of shares.

                  (d) After full payment of the Series A Preferred Return, to
the extent the Corporation has legally available funds, the Corporation shall
redeem the Series B Preferred at the following times and in the following
amounts: (i) upon the occurrence of a Sales Transaction, Distributable Cash in
the amount necessary to cause each holder of Series B Preferred to receive its
Series B Preferred Return shall be distributed to the holders of Series B
Preferred; (ii) within 45 days after the end of each calendar quarter and until
each holder of Series B Preferred has received its Series B Preferred Return,
the Corporation shall distribute an amount of Distributable Cash to the holders
of Series B Preferred equal to at least 25% of the Corporation's net operating
cash flow for the perceeding quarter (provided that, to the extent such funds
are necessary for the Corporation's operations, any such quarterly distribution
may be waived by the vote of at least five (5) directors of the Corporation);
and (iii) at such other times and in such amounts as the Board of Directors of
the Corporation, in its sole discretion, may determine.

         (5) Voting Rights. Except as otherwise required by law or by Section 8
below, the holder of each share of Series B Preferred will not be entitled to
vote on any matters.

         (6) Notices of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or other distribution, any right to subscribe for, purchase or
otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right, the Corporation shall mail to each
holder of Series B Preferred, at least ten (10) days prior to the date specified
therein, a notice specifying the date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and the amount and
character of such dividend, distribution or right.

         (7) Notices. Any notice required by the provisions of this Certificate
of Incorporation to be given to the holders of Series B Preferred shall be
deemed given when deposited in the United States mail, postage prepaid, and
addressed to each holder of record at such holder's address appearing on the
books of the Corporation.

         (8) Approval of Certain Transactions While Any Series B Preferred is
Outstanding. So long as any shares of Series B Preferred are outstanding, the
Corporation shall not, without



                                      -10-
<PAGE>   11

first obtaining the approval of the holders of at least a majority of the shares
of Series B Preferred then outstanding, voting as a separate class, take any
action that:

                  (a) alters the rights, preferences or privileges of the Series
B Preferred;

                  (b) creates any new class or series of shares that has a
preference over or is on a parity with the Series B Preferred with respect to
dividends or liquidation preferences;

                  (c) reclassifies or amends the term of any capital stock into
shares having a preference over or parity with the Series B Preferred with
respect to dividends or liquidation preferences; or

                  (d) repurchases, redeems or retires any shares of capital
stock of the Corporation other than as permitted in Section 2(b) above.

         FIFTH. No stockholder of the Corporation will, solely by reason of
holding shares of any class, have any preemptive or preferential right to
purchase or subscribe for any shares of the Corporation, now or hereafter to be
authorized, or any notes, debentures, bonds or other securities convertible into
or carrying warrants, rights or options to purchase shares of any class, now or
hereafter to be authorized, whether or not the issuance of any such shares or
such notes, debentures, bonds or other securities would adversely affect the
dividend, voting or any other rights of such stockholder. The Board of Directors
may authorize the issuance of, and the Corporation may issue, shares of any
class of the Corporation, or any notes, debentures, bonds or other securities
convertible into or carrying warrants, rights or options to purchase any such
shares, without offering any shares of any class to the existing holders of any
class of stock of the Corporation.

         SIXTH. Stockholders of the Corporation will not have the right of
cumulative voting for the election of directors or for any other purpose.

         SEVENTH. The Board of Directors is expressly authorized to alter, amend
or repeal the Bylaws of the Corporation or to adopt new Bylaws.

         EIGHTH. (a) The Corporation will, to the fullest extent permitted by
the Delaware General Corporation Law, as the same exists or may hereafter be
amended, indemnify any and all persons it has power to indemnify under such law
from and against any and all of the expenses, liabilities or other matters
referred to in or covered by such law. Such indemnification may be provided
pursuant to any Bylaw, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in his director or officer capacity
and as to action in another capacity while holding such office, will continue as
to a person who has ceased to be a director, officer, employee or agent, and
will inure to the benefit of the heirs, executors and administrators of such a
person.



                                      -11-
<PAGE>   12

         (b) If a claim under the preceding paragraph (a) is not paid in full by
the Corporation within 30 days after a written claim has been received by the
Corporation, the claimant may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part, the claimant will be entitled to be paid also the expense of
prosecuting such claim. It will be a defense to any such action (other than an
action brought to enforce a claim for expenses incurred in defending any
proceeding in advance of its final disposition where the required undertaking,
if any is required, has been tendered to the Corporation) that the claimant has
not met the standards of conduct that make it permissible under the laws of the
State of Delaware for the Corporation to indemnify the claimant for the amount
claimed, but the burden of proving such defense will be on the Corporation.
Neither the failure of the Corporation (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such action that indemnification of the claimant is
proper in the circumstances because he has met the applicable standard of
conduct set forth in the laws of the State of Delaware nor an actual
determination by the Corporation (including its Board of Directors, independent
legal counsel, or its stockholders) that the claimant has not met such
applicable standard of conduct, will be a defense to the action or create a
presumption that the claimant has not met the applicable standard of conduct.

         NINTH. To the fullest extent permitted by the laws of the State of
Delaware as the same exist or may hereafter be amended, a director of the
Corporation will not be liable to the Corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director. Any repeal or
modification of this Article will not increase the personal liability of any
director of the Corporation for any act or occurrence taking place before such
repeal or modification, or adversely affect any right or protection of a
director of the Corporation existing at the time of such repeal or modification.
The provisions of this Article Nine shall not be deemed to limit or preclude
indemnification of a director by the Corporation for any liability of a director
that has not been eliminated by the provisions of this Article Nine.

         TENTH: The address of the Corporation's initial registered office is
1209 Orange Street, Wilmington, Delaware 19801, County of New Castle, and the
name of its initial registered agent at that address is The Corporation Trust
Company.

         ELEVENTH. The number of directors constituting the initial Board of
Directors of the Corporation is seven and the names and mailing addresses of
such persons, who are to serve as directors until the first annual meeting of
the stockholders or until their successors are elected and qualified, are:

approved by the Board of Directors; (ii) pursuant to any option, warrants, right
or convertible or exchangeable security of the Corporation outstanding as of the
date of filing of this Certificate of Designations with the Secretary of State
of Delaware (although the terms of which may be changed after said date); or

and subject to adjustment in the event of a stock split, stock dividend,
recapitalization or the like). The Issuance Consideration is initially $9.00 per
share. To the extent that shares of Series C Stock are issued in the Offering at
a lower price per share, then the Issuance Consideration will be changed to such
lower dollar amount, and all holders of Series C


                                       2

         2.       Dividends.

         (a) In the event the Board of Directors shall declare a cash dividend
payable upon the outstanding shares of Common Stock out of funds of the
Corporation legally available therefor pursuant to the General Corporation Law
of the State of Delaware ("Legally Available Funds"), the Board of Directors
shall at the same time declare a dividend payable on each share of Series C
Stock equal to the amount of the dividend payable on the number of shares of
Common Stock into which


                                       3
<PAGE>   4


each such share of Series C Stock could then be converted into pursuant to the
provisions of Section 5 below, such number to be determined as of the record
date for the determination of holders of Common Stock entitled to receive such
dividends.

         3.       Preference on Dissolution, Liquidation or Winding Up.

         (a) In the event of the occurrence of a Liquidation Event, the holders
of Series C Stock shall be entitled to receive, in preference to the holders of
Common Stock or any other class of stock or series thereof ranking junior to the
Series C Stock with respect to the distribution of assets, an amount equal to
the product of the number of shares of Series C Stock held multiplied by the
Issuance Consideration, plus an amount equal to all dividends accrued and unpaid
thereon (including interest accrued thereon, if applicable) to the date fixed
for distribution, and no more (the "Liquidation Preference"). If Legally
Available Assets for distribution upon the occurrence of a Liquidation Event are
insufficient to satisfy in full the Liquidation Preference, then the Liquidation
Preference shall be reduced to such amount as can be satisfied out of the
Legally Available Assets, and such amounts shall be paid to the holders of the
Series C Stock on a pari passu basis (based on the number of shares of Series C
Stock held).

         (b) Written notice of the occurrence of a Liquidation Event, stating a
payment date and the place where the distributable amounts shall be payable
shall be given by mail, postage prepaid, not less than 20 days prior to the
payment date stated therein, to the holders of record of the Series C Stock at
their respective addresses as the same shall appear on the books of the
Corporation.

         (c) No payment on account of such Liquidation Event shall be made to
the holders of any class or series of capital stock ranking on a parity with the
Series C Stock in respect of the distribution of assets, unless there shall
likewise be paid at the same time to the holders of the Series C Stock like
proportionate distributive amounts, ratably, in proportion to the full
distributive amounts to which they and the holders of such parity stock are
respectively entitled with respect to such preferential distribution.

         4. Voting Rights. Except as otherwise provided in this Certificate of
Designations, each holder of Series C Stock shall be entitled to vote on all
matters submitted for a vote of the holders of Common Stock a number of votes
equal to the number of full shares of Common Stock into which such holder's
shares of Series C Stock could then be converted pursuant to the provisions of
Paragraph 5 below, such number to be determined as of the record date for the
determination of holders of Common Stock entitled to vote on any such matter,
or, if no record date is fixed , then the record date for determination of
holders of Series C Stock entitled to vote at a meeting of stockholders shall be
at the close of business on the day next preceding the day on which such meeting
is held. Except as otherwise required in this Certificate of Designations or by
the Delaware General Corporation Law, the holders of the Series C Stock shall
vote with the holders of outstanding Common Stock and any other preferred shares
entitled to vote on any such matter, and not as a separate class or series.


                                       4

         5. Conversion Rights. Each share of Series C Stock may be converted
into shares of Common Stock on the terms and conditions set forth in this
Section 5:

         (a) Each share of Series C Stock shall be convertible at the option of
the holder thereof, at any time and from time to time, in the manner hereinafter
set forth, into a number of fully-paid and nonassessable shares of Common Stock
(rounded to the nearest whole number) at the Conversion Rate in effect at the
time of conversion determined as hereinafter provided.

         (b) Each share of Series C Stock shall convert automatically, and
without any action on the part of the holder thereof, into the number of
fully-paid and nonassessable shares of Common Stock (rounded to the nearest
whole number) determined by applying the Conversion Rate then in effect upon the
earliest to occur of the following: (i) immediately prior to the consummation of
a firm commitment underwritten public offering of Common Stock pursuant to a
registration statement filed with the Securities and Exchange Commission and
having a per share price equal to or exceeding $12.00 per share (as adjusted for
stock splits, stock dividends, recapitalizations and the like) and a total gross
offering amount of not less than $15 million; (ii) the date that, through
redemption or conversion, fewer than 150,000 shares of Series C Stock remain
outstanding (as adjusted for stock splits, stock dividends, recapitalizations
and the like); (iii) immediately prior to the consummation of a Non-Surviving
Combination; provided, that the value received by the holders of Series C Stock
equals or exceeds $15.00 per share; or (iv) upon the vote of the holders of a
majority of the then issued and outstanding shares of Series C Stock (each of
the above is sometimes referred to herein as a "Conversion Event" and
collectively, as the "Conversion Events").

         (c) Upon conversion of any Series C Stock, all accrued and unpaid
dividends on the Series C Stock so converted shall be paid in cash.

         (d) Upon the occurrence of a Conversion Event, the Corporation shall
prepare a notice stating that a Conversion Event has occurred and setting forth
in detail the facts, and such notice shall forthwith be mailed by first class
mail to the holders of the Series C Stock at their last known address shown on
the stock books of the Corporation.

         (e) Upon receipt of written notice of a Conversion Event, each holder
of Series C Stock shall (i) surrender the certificate or certificates therefor,
duly endorsed, at the office of any transfer agent for such Series C Stock, or
if there is no such transfer agent, then at the principal executive offices of
the Corporation and (ii) state in writing therein the name or names in which
such holder wishes the certificate or certificates for the Common Stock to be
issued. The Corporation shall, as soon as practicable thereafter, issue and
deliver at the last known address of each holder of the Series C Stock, or to
his nominee or nominees, certificates for the number of full shares of Common
Stock to which he shall be entitled, as aforesaid, together with cash in lieu of
any fraction of a share as hereinafter provided. Such conversion shall be deemed
to have been made on the date of the Conversion Event, and the person or persons
entitled to receive the Common Stock issuable upon such conversion shall be
treated for all purposes as the record holder or holders of such Common Stock on
said date.


                                       5
<PAGE>   6


         (f) If the Corporation shall at any time (i) pay or make a dividend or
other distribution on any class or series of capital stock of the Corporation in
Common Stock, (ii) subdivide (by means of a stock split or otherwise) its
outstanding Common Stock into a larger number of shares or (iii) combine (by
means of a reverse stock split or otherwise) its outstanding Common Stock into a
smaller number of shares, the Conversion Rate for the Series C Stock in effect
immediately prior thereto shall be adjusted so that each share of Series C Stock
shall thereafter be convertible into the number of shares of Common Stock which
the holder of one share of Series C Stock would have been entitled to receive
after the happening of any of the events described above had such stock been
converted into Common Stock immediately prior to the record date, if any, in the
case of a dividend, distribution, subdivision or combination with respect to
which the Corporation has fixed a record date for the determination of
stockholders entitled to receive such dividend, distribution, subdivision or
combination or, if no such record date has been fixed, the effective date of
such dividend, distribution, subdivision or combination. An adjustment made
pursuant to this subparagraph (f) shall be effected at the time such dividend or
distribution is made or paid or such subdivision or combination is effected and
shall be effective retroactively with respect to conversions effected subsequent
to any record date described in the immediately preceding sentence.

         (g) In case at any time or from time to time the Corporation shall pay
any dividend or make any other distribution to the holders of Common Stock of
(i) any securities or property of any nature whatsoever (other than cash or as
provided in subparagraph (f) above), or (ii) any warrants or other rights to
subscribe for or purchase capital stock of the Corporation, then the Conversion
Rate shall be adjusted to that number determined by multiplying the Conversion
Rate immediately prior to such adjustment by a fraction (A) the numerator of
which shall be the fair value (as determined in good faith by the Board of
Directors) per share of Common Stock at the date of taking such record and (B)
the denominator of which shall be such fair value per share of Common Stock
minus the portion applicable to one share of Common Stock of the fair value (as
determined in good faith by the Board of Directors) of any and all such
securities or property to be distributed. A reclassification of the Common Stock
into Common Stock and shares of any other class of securities shall be deemed a
distribution by the Corporation to the holders of its Common Stock of such other
Common Stock and of such other class of securities within the meaning of this
subparagraph and, if the outstanding Common Stock shall be changed into a larger
or smaller number of shares of Common Stock as a part of such reclassification,
such change shall be deemed a subdivision or combination, an the case may be, of
the outstanding Common Stock within the meaning of subparagraph (f) above.

         (h) In case at any time or from time to time the Corporation shall
issue or sell any Additional Stock for a consideration per share less than the
Issuance Consideration, then the Conversion Rate shall be adjusted to that
number determined by multiplying the Conversion Rate immediately prior to such
adjustment by a fraction (i) the numerator of which shall be the number of
shares of Common Stock (including shares of Common Stock underlying the Series C
Stock) outstanding immediately prior to the issuance of such shares of
Additional Stock plus the number of such shares of Additional Stock so issued
and (ii) the denominator of which shall be the number of shares of Common Stock
(including shares of Common Stock underlying the Series C Stock)


                                       6
<PAGE>   7


outstanding immediately prior to the issuance of the shares of Additional Stock
plus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Additional Stock so issued would purchase at
the Conversion Price in effect immediately prior to the issuance of the
Additional Stock. For the purposes of this subparagraph, the date as of which
the Conversion Price of the Common Stock shall be computed shall be the earlier
of (i) the date on which the Corporation shall enter into a firm contract for
the issuance of such Additional Stock or (ii) the date of actual issuance of
such Additional Stock. The provisions of this subparagraph shall not apply to
any issuance of Additional Stock for which an adjustment to provided under
subparagraph (g) above. No adjustment of the Conversion Rate shall be made under
this subparagraph upon the issuance of any shares of Additional Stock which are
issued pursuant to the exercise of any warrants or any other subscription or
purchase rights or pursuant to the exercise of any conversion or exchange rights
in any Convertible Securities, if any such adjustment shall previously have been
made upon the issuance of such warrants or other rights or upon the issuance of
such Convertible Securities (or upon the issuance of any warrant or other rights
therefor) pursuant to subparagraph 6(f) or (g) above.

         (i) In case at any time or from time to time the Corporation shall
distribute or shall in any manner (whether directly or indirectly) issue or sell
any Convertible Securities (excluding Exempt Issuances), whether or not the
rights to exchange or convert thereunder are immediately exercisable, and the
consideration per share for which additional Common Stock may at any time
thereafter be issuable pursuant to such warrants, options or other rights or
pursuant to the terms of such Convertible Securities shall be less than the
Issuance Consideration, then the Conversion Rate shall adjusted as provided in
subparagraph (h) above on the basis that (i) the maximum number of shares of
Additional Stock issuable pursuant to all such Convertible Securities on the
date of issuance of such Convertible Securities shall be deemed to have been
issued as of the date of the determination of the Conversion Price as
hereinafter provided, and (ii) the aggregate consideration for such maximum
number of shares of Additional Stock shall be deemed to be the minimum
consideration received and receivable by the Corporation for the issuance of
such Convertible Securities. For the purposes of this subparagraph, the date on
which the Conversion Price shall be computed shall be the earliest of (i) the
date on which the Corporation shall take a record of the holders of its Common
Stock for the purpose of entitling them to receive any such Convertible
Securities, (ii) the date on which the Corporation shall enter into a firm
contract for the issuance of such Convertible Securities or (iii) the date of
actual issuance of such Convertible Securities. No adjustment of the Conversion
Rate shall be made under this subparagraph upon the issuance of any Convertible
Securities which are issued pursuant to the exercise of any warrants or any
subscription or purchase rights therefor, if any such adjustment shall
previously have been made upon the issuance of such warrants or other rights
pursuant to any of the above subparagraphs.

         (j) If, at any time after any adjustment of the Conversion Rate shall
have been made pursuant to any of the above subparagraphs on the basis of the
issuance of Convertible Securities, or after any new adjustments of the
Conversion Rate shall have been made pursuant to this subparagraph (j),


                                       7
<PAGE>   8


                  (i) such warrants or rights or the right of conversion or
         exchange in such other Convertible Securities shall expire, and a
         portion of such warrants or rights, or the right of conversion or
         exchange in respect of a portion of such other Convertible Securities,
         as the came may be, shall not have been exercised, and/or

                  (ii) the consideration per share, of which shares of Common
         Stock are issuable pursuant to such warrants or rights or the terms of
         such other Convertible Securities, shall be increased solely by virtue
         of provisions therein contained for an automatic increase in such
         consideration per share upon the arrival of a specified date or the
         happening of a specified event,

such previous adjustment shall be rescinded and annulled as to any shares of
Series C Stock then outstanding and the shares of Common Stock which were deemed
to have been issued by virtue of the computation made in connection with the
adjustment so rescinded and annulled, shall no longer be deemed have been issued
by virtue of such computation. Thereupon, a recomputation (assuming that all
shares of Series C Stock on the date of the initial computation are outstanding
on the date of such recomputation) shall be made of the affect of such rights or
options or other Convertible Securities on the basis of

                  (i) treating the number of shares of Common Stock, if any,
         theretofore issued or issuable pursuant to the previous exercise of
         such warrants or rights or right of conversion or exchange, as having
         been issued on the date or dates of such exercise and for the
         consideration actually received and receivable therefor, and

                  (ii) treating any such warrants or rights or any such other
         Convertible Securities which then remain outstanding as having been
         granted or issued immediately after the time of such increase of the
         consideration per share for which shares of Common Stock are issuable
         under such warrants or rights or other Convertible Securities; and, if
         and to the extent called for by the foregoing provisions of this
         Paragraph on the basis aforesaid, a new adjustment of the Conversion
         Rate shall be made, which new adjustment shall supersede the previous
         adjustment so rescinded and annulled.

         (k) The following provisions of this subparagraph (k) shall also be
applicable to the making of adjustments to the Conversion Rate:

                  (i) To the extent that any Additional Stock or any Convertible
         Securities or any warrants or other rights to subscribe for or purchase
         any Additional Stock or any Convertible Securities shall be issued for
         a cash consideration, the consideration received by the Corporation
         therefor shall be deemed to be the amount of the cash received by the
         Corporation therefor, or, if such Additional Stock or Convertible
         Securities are offered by the Corporation for subscription, the
         subscription price, or, if such Additional Stock or Convertible
         Securities are sold to underwriters or dealers for public offering
         without a subscription offering, the initial public offering price, in
         any such case without deduction of


                                       8
<PAGE>   9



         any compensation, discounts or expenses paid or incurred by the
         Corporation for and in the underwriting of, or otherwise in connection
         with, the issuance thereof. To the extent that such issuance shall be
         for a consideration other than cash, then except as herein otherwise
         expressly provided, the amount of such consideration shall be deemed to
         be the fair value of such consideration at the time of such issuance as
         determined in good faith by the Board of Directors. In case any shares
         of Additional Stock or any Convertible Securities or warrants or other
         rights to subscribe for or purchase such Additional Stock or
         Convertible Securities shall be issued in connection with any
         consolidation or merger in which the Corporation issues any securities,
         the amount of consideration therefor shall be deemed to be the fair
         value, as determined in good faith by the Board of Directors, of such
         portion of the assets and business of the non-surviving corporation as
         such Board of Directors in good faith shall determine to be
         attributable to such Additional Stock, Convertible Securities, warrants
         or other rights, as the case may be. The consideration for any
         Additional Stock issuable pursuant to any warrants or other rights to
         subscribe for or purchase the same shall be the consideration received
         by the Corporation for issuing such warrants or other rights, plus the
         minimum additional consideration payable to the Corporation upon the
         exercise of such warrants or other rights. The consideration for any
         Additional Stock issuable pursuant to the terms of any Convertible
         Securities shall be the consideration received by the Corporation for
         issuing any warrants or other rights to subscribe for or purchase such
         Convertible Securities, plus the minimum consideration paid or payable
         to the Corporation in respect of the subscription for or purchase of
         such Convertible Securities, plus the minimum additional consideration,
         if any, payable to the Corporation upon the exercise of the right of
         conversion or exchange in such Convertible Securities. In case of the
         issuance at any time of any Additional Stock or Convertible Securities
         in payment or satisfaction of any dividends upon any class of capital
         stock other than Common Stock, the Corporation shall be deemed to have
         received for such Additional Stock or Convertible Securities
         consideration equal to the amount of such dividend so paid or
         satisfied.

                  (ii) The adjustments required by this Paragraph 5 shall be
         made whenever and as often as any specified event requiring an
         adjustment shall occur, except that no adjustment shall be made (except
         in the case of a subdivision or combination of shares of the Common
         Stock, as provided for in subparagraph(f) above) unless and until such
         adjustment either by itself or with other adjustments not previously
         made adds or subtracts at least 1/20th of a share to or from the
         Conversion Rate in effect immediately prior to the making of such
         adjustment. Any adjustment representing a change of less than such
         minimum amount (except as aforesaid) shall be carried forward and made
         so soon as such adjustment, together with other adjustments required by
         this Paragraph 5 and not previously made, would result in a minimum
         adjustment. For the purpose of any adjustment, any specified event
         shall be deemed to have occurred at the close of business on the date
         of its occurrence.

                  (iii) If the Corporation shall take a record of the holder of
         its Common Stock for the purpose of entitling them to receive a
         dividend or distribution or subscription or purchase rights and shall,
         thereafter and before the distribution to stockholders thereof, legally


                                       9
<PAGE>   10


         abandon its plan to pay or deliver such dividend, distribution,
         subscription or purchase rights, then thereafter no adjustment shall be
         required by reason of the taking of such record and any such adjustment
         previously made in respect thereof shall be rescinded and annulled.

         (l) In the case of a merger, or the sale or conveyance of all or
substantially all of the assets of the Corporation for which approval of the
holders of the Common Stock is necessary, or in the case of any capital
reorganization or any reclassification or similar change of the outstanding
Common Stock (other than as at forth in subparagraph (f) above), each share of
Series C Stock, if any, outstanding following such transaction shall thereafter
be convertible into the kind and amount of securities or other securities or
cash or other property receivable upon such merger, sale, conveyance,
reorganization, reclassification or change by a holder of the number of shares
of Common Stock into which such Series C Stock might have been converted
immediately prior to such merger, sale, conveyance reorganization,
reclassification or change, assuming such holder of Common Stock failed to
exercise his rights of election, if any, as to the kind and amount of stock or
other securities or cash or other property receivable upon such merger, sale,
conveyance, reorganization, reclassification or change (provided that if the
kind and amount of stock or other securities or cash or other property
receivable upon such merger, sale, conveyance, reorganization, reclassification
or change is not the same for each share of Common Stock in respect of which
such rights of election shall not have been exercised ("non-electing shares")
then for the purpose of this subparagraph the kind and amount of stock or other
securities or cash or other property receivable upon such merger, sale,
conveyance, reorganization, reclassification or change by each non-electing
share shall be deemed to be the kind and amount so receivable by a plurality of
the non-electing share); and, in any such case, appropriate adjustments (as
determined in good faith by the Board of Directors) shall be made in the
application of the provisions herein set forth with respect to the rights and
interests thereafter of the holders of the Series C Stock to the and that the
provisions set forth heroin (including provisions with respect to changes in and
other adjustments of the Conversion Rate) shall thereafter be applicable, as
nearly as reasonably may be, in relation to any stock or other property
thereafter deliverable upon the conversion of the Series C Stock.

         (m) Whenever the Conversion Rate or terms of conversion are adjusted or
readjusted as herein provided, the Corporation shall prepare a notice setting
forth such adjustment or readjustment and showing in detail the facts upon which
each adjustment or readjustment is based, and such notice shall forthwith be
mailed by first class mail to the holders of shares of Series C Stock so
affected at their last known address shown on the stock books of the
Corporation.

         (n) The Corporation shall at all times reserve and keep available, out
of its authorized but unissued Common Stock or out of Common Stock held in its
treasury, solely for the purpose of effecting the conversion of the Series C
Stock, the full number of shares of Common Stock deliverable upon the conversion
of all Series C Stock from time to time outstanding. The Corporation shall from
time to time in accordance with the General Corporation Law of the State of
Delaware increase the authorized amount of its Common Stock if at any time the
authorized number of share of Common Stock remaining unissued shall not be
sufficient to permit the conversion of all of the Series C Stock outstanding
from time to time.


                                       10
<PAGE>   11


         (o) No fractional shares of Common Stock are to be delivered upon
conversion, but the Corporation shall pay a cash adjustment in respect of any
fraction of a share which would otherwise be deliverable in an amount equal to
the same fraction of the current market price per share of Common Stock on the
date of conversion, such current market price to be determined in good faith by
the Board of Directors.

         (p) The Corporation will pay any issue and other taxes (other than
income taxes) that may be payable in respect of any issue or delivery of Common
Stock on conversion of Series C Stock pursuant hereto. The Corporation shall
not, however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of stock in a name other than that
in which the shares of Series C Stock so converted were registered, and no such
issue or delivery shall be made unless and until the person requesting such
issue or delivery has paid to the Corporation the amount of any such tax, or has
established, to the satisfaction of the Corporation, that such tax has been
paid.

         6. Notices of Record Date. In the event that the Corporation shall
propose at any time:

         (a) to declare any dividend or distribution upon its Common Stock,
whether in cash, property, stock or other securities, whether or not a regular

                                       OF

                           MOBILITY ELECTRONICS, INC.


                                    ARTICLE I

                                     OFFICES

         Section 1. Registered Office. The registered office and registered
agent of Mobility Electronics, Inc. (the "Corporation") will be as from time to
time set forth in the Corporation's Certificate of Incorporation or in any
certificate filed with the Secretary of State of the State of Delaware, and the
appropriate county Recorder or Recorders, as the case may be, to amend such
information.

         Section 2. Other Offices. The Corporation may also have offices at such
other places both within and without the State of Delaware as the Board of
Directors may from time to time determine or the business of the Corporation may
require.

                                   ARTICLE II

                                  STOCKHOLDERS

         Section 1. Place of Meetings. All meetings of the stockholders for the
election of Directors will be held at such place, within or without the State of
Delaware, as may be fixed from time to time by the Board of Directors. Meetings
of stockholders for any other purpose may be held at such time and place, within
or without the State of Delaware, as may be stated in the notice of the meeting
or in a duly executed waiver of notice thereof.

         Section 2. Annual Meeting. An annual meeting of the stockholders will
be held at such time as may be determined by the Board of Directors, at which
meeting the stockholders will elect a Board of Directors, and transact such
other business as may properly be brought before the meeting.

         Section 3. List of Stockholders. At least ten days before each meeting
of stockholders, a complete list of the stockholders entitled to vote at said
meeting, arranged in alphabetical order, with the address of and the number of
voting shares registered in the name of each, will be prepared by the officer or
agent having charge of the stock transfer books. Such list will be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city where the meeting is to be held, which place
will be specified in the notice of the meeting, or if not so specified at the
place where the meeting is to be held. Such list will be produced and kept open
at the time and place of the meeting during the whole time thereof, and will be
subject to the inspection of any stockholder who may be present.


<PAGE>   5


         Section 4. Special Meetings. Special meetings of the stockholders, for
any purpose or purposes, unless otherwise prescribed by law, the Certificate of
Incorporation or these Bylaws, may be called by the Chairman of the Board, the
President or the Board of Directors. Business transacted at all special meetings
will be confined to the purposes stated in the notice of the meeting unless all
stockholders entitled to vote are present and consent.

         Section 5. Notice. Written or printed notice stating the place, day and
hour of any meeting of the stockholders and, in case of a special meeting, the
purpose or purposes for which the meeting is called, will be delivered not less
than ten nor more than sixty days before the date of the meeting, either
personally or by mail, by or at the direction of the Chairman of the Board, the
President, the Secretary, or the officer or person calling the meeting, to each
stockholder of record entitled to vote at the meeting. If mailed, such notice
will be deemed to be delivered when deposited in the United States mail,
addressed to the stockholder at his address as it appears on the stock transfer
books of the Corporation, with postage thereon prepaid.

         Section 6. Quorum. At all meetings of the stockholders, the presence in
person or by proxy of the holders of a majority of the shares issued and
outstanding and entitled to vote will be necessary and sufficient to constitute
a quorum for the transaction of business except as otherwise provided by law,
the Certificate of Incorporation or these Bylaws. If, however, such quorum is
not present or represented at any meeting of the stockholders, the stockholders
entitled to vote thereat, present in person or represented by proxy, will have
power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum is present or represented. If the
adjournment is for more than 30 days, or if after the adjournment a new record
date is fixed for the adjourned meeting, a notice of the adjourned meeting will
be given to each stockholder of record entitled to vote at the meeting. At such
adjourned meeting at which a quorum is present or represented, any business may
be transacted that might have been transacted at the meeting as originally
notified.

         Section 7. Voting. When a quorum is present at any meeting of the
Corporation's stockholders, the vote of the holders of a majority of the shares
entitled to vote on, and voted for or against, any matter will decide any
questions brought before such meeting, unless the question is one upon which, by
express provision of law, the Certificate of Incorporation or these Bylaws, a
different vote is required, in which case such express provision will govern and
control the decision of such question. The stockholders present in person or by
proxy at a duly organized meeting may continue to transact business until
adjournment, notwithstanding the withdrawal of enough stockholders to leave less
than a quorum.

         Section 8. Method of Voting. Each outstanding share of the
Corporation's capital stock, regardless of class, will be entitled to one vote
on each matter submitted to a vote at a meeting of stockholders, except to the
extent that the voting rights of the shares of any class or classes are limited
or denied by the Certificate of Incorporation, as amended from time to time. At
any meeting of the stockholders, every stockholder having the right to vote will
be entitled to vote in person, or by proxy appointed by an instrument in writing
subscribed by such stockholder and bearing a date

                                       -2-

<PAGE>   6


not more than three years prior to such meeting, unless such instrument provides
for a longer period. Each proxy will be revocable unless expressly provided
therein to be irrevocable and if, and only as long as, it is coupled with an
interest sufficient in law to support an irrevocable power. A proxy may be made
irrevocable regardless of whether the interest with which it is coupled is an
interest in the stock itself or an interest in the Corporation generally. Such
proxy will be filed with the Secretary of the Corporation prior to or at the
time of the meeting. Voting on any question or in any election, other than for
directors, may be by voice vote or show of hands unless the presiding officer
orders, or any stockholder demands, that voting be by written ballot.

         Section 9. Record Date. The Board of Directors may fix in advance a
record date for the purpose of determining stockholders entitled to notice of or
to vote at a meeting of stockholders, which record date will not precede the
date upon which the resolution fixing the record date is adopted by the Board of
Directors, and which record date will not be less than ten nor more than sixty
days prior to such meeting. In the absence of any action by the Board of
Directors, the close of business on the date next preceding the day on which the
notice is given will be the record date, or, if notice is waived, the close of
business on the day next preceding the day on which the meeting is held will be
the record date.

         Section 10. Action by Consent. Any action required or permitted by law,
the Certificate of Incorporation or these Bylaws to be taken at a meeting of the
stockholders of the Corporation may be taken without a meeting if a consent or
consents in writing, setting forth the action so taken, is 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 and will be delivered to the
Corporation by delivery to its registered office in Delaware, its principal
place of business or an officer or agent of the Corporation having custody of
the minute book.

                                   ARTICLE III

                               BOARD OF DIRECTORS

         Section 1. Management. The business and affairs of the Corporation will
be managed by or under the direction of its Board of Directors who may exercise
all such powers of the Corporation and do all such lawful acts and things as are
not by law, by the Certificate of Incorporation or by these Bylaws directed or
required to be exercised or done by the stockholders.

         Section 2. Qualification; Election; Term. None of the Directors need be
a stockholder of the Corporation or a resident of the State of Delaware. The
Directors will be elected by written ballot, by plurality vote at the annual
meeting of the stockholders, except as hereinafter provided, and each Director
elected will hold office until whichever of the following occurs first: his
successor is elected and qualified, his resignation, his removal from office by
the stockholders or his death.

                                       -3-

<PAGE>   7



         Section 3. Number; Election; Term; Qualification. The number of
Directors which shall constitute the Board of Directors shall be not less than
one. The first Board of Directors shall consist of the number of Directors named
in the Certificate of Incorporation. Thereafter, the number of Directors which
shall constitute the entire Board of Directors shall be determined by resolution
of the Board of Directors at any meeting thereof, but shall never be less than
one. The Board of Directors of the Corporation shall be divided into three
classes which shall be as nearly equal in number as is possible. At the first
election of Directors to such classified Board of Directors, each Class I
Director shall be elected to serve until the next ensuing annual meeting of
stockholders, each Class II Director shall be elected to serve until the second
ensuing annual meeting of stockholders, each Class III Director shall be elected
to serve until the third ensuing annual meeting of stockholders. At each annual
meeting of stockholders following the meeting at which the Board of Directors is
initially classified, the number of Directors equal to the number of the class
whose term expires at the time of such meeting shall be elected to serve until
the third ensuing annual meeting of stockholders. At each annual meeting of
stockholders, Directors shall be elected to hold office until their successors
are elected and qualified or until their earlier resignation, removal from
office or death. No Director need be a stockholder, a resident of the State of
Delaware, or a citizen of the United States.

         Section 4. Changes in Number. In the event of any change in the
authorized number of Directors, the number of Directors in each class shall be
adjusted so that thereafter each of the three classes shall be composed, as
nearly as may be possible, of one-third of the authorized number of Directors;
provided that any change in the authorized number of Directors shall not
increase or shorten the term of any Director, and any decrease shall become
effective only as and when the term or terms of office of the class or classes
of Directors affected thereby shall expire, or a vacancy or vacancies in such
class or classes shall occur. Any directorship to be filled by reason of an
increase in the number of Directors may be filled by (i) the stockholders at any
annual or special meeting of stockholders called for that purpose or (ii) the
Board of Directors for a term of office continuing only until the next election
of one or more Directors by the stockholders. Notwithstanding the foregoing,
whenever the holders of any class or series of shares are entitled to elect one
or more Directors by the provisions of the Certificate of Incorporation, any
newly created directorship(s) of such class or series to be filled by reason of
an increase in the number of such Directors may be filled by the affirmative
vote of a majority of the Directors elected by such class or series then in
office or by a sole remaining Director so elected or by the vote of the holders
of the outstanding shares of such class or series, and such directorship(s)
shall not in any case be filled by the vote of the remaining Directors or by the
holders of the outstanding shares of the Corporation as a whole unless otherwise
provided in the Certificate of Incorporation.

         Section 5. Removal. Any Director may be removed either for or without
cause, at any special meeting of stockholders by the affirmative vote of a
majority in number of shares of the stockholders present in person or
represented by proxy at such meeting and entitled to vote for the election of
such Director; provided that notice of the intention to act upon such matter has
been given in the notice calling such meeting.

                                       -4-

<PAGE>   8



         Section 6. Vacancies. Vacancies occurring in the Board of Directors
caused by death, resignation, retirement, disqualification or removal from
office of any Directors or otherwise, may be filled by the vote of a majority of
the Directors then in office, though less than a quorum, or a successor or
successors may be chosen at a special meeting of the stockholders called for
that purpose, and each successor Director so chosen will hold office until the
next election of the class for which such Director has been chosen or until
whichever of the following occurs first: his successor is elected and qualified,
his resignation, his removal from office by the stockholders or his death.

         Section 7. Place of Meetings. Meetings of the Board of Directors,
regular or special, may be held at such place within or without the State of
Delaware as may be fixed from time to time by the Board of Directors.

         Section 8. Annual Meeting. The first meeting of each newly elected
Board of Directors will be held without further notice immediately following the
annual meeting of stockholders and at the same place, unless by unanimous
consent, the Directors then elected and serving change such time or place.

         Section 9. Regular Meetings. Regular meetings of the Board of Directors
may be held without notice at such time and place as is from time to time
determined by resolution of the Board of Directors.

         Section 10. Special Meetings. Special meetings of the Board of
Directors may be called by the Chairman of the Board or the President on oral or
written notice to each Director, given either personally, by telephone, by
telegram or by mail; special meetings will be called by the Chairman of the
Board, President or Secretary in like manner and on like notice on the written
request of at least two Directors. The purpose or purposes of any special
meeting will be specified in the notice relating thereto.

         Section 11. Quorum. At all meetings of the Board of Directors the
presence of a majority of the number of Directors fixed by these Bylaws will be
necessary and sufficient to constitute a quorum for the transaction of business,
and the affirmative vote of at least a majority of the Directors present at any
meeting at which there is a quorum will be the act of the Board of Directors,
except as may be otherwise specifically provided by law, the Certificate of
Incorporation or these Bylaws. If a quorum is not present at any meeting of the
Board of Directors, the Directors present thereat may adjourn the meeting from
time to time without notice other than announcement at the meeting, until a
quorum is present.

         Section 12. Interested Directors. No contract or transaction between
the Corporation and one or more of its Directors or officers, or between the
Corporation and any other corporation, partnership, association or other
organization in which one or more of the Corporation's Directors or officers are
directors or officers or have a financial interest, will be void or voidable
solely for this reason, solely because the Director or officer is present at or
participates in the meeting of the Board

                                       -5-

<PAGE>   9



of Directors or committee thereof that authorizes the contract or transaction,
or solely because his or their votes are counted for such purpose, if: (i) the
material facts as to his relationship or interest and as to the contract or
transaction are disclosed or are known to the Board of Directors or the
committee, and the Board of Directors or committee in good faith authorizes the
contract or transaction by the affirmative vote of a majority of the
disinterested Directors, even though the disinterested Directors be less than a
quorum, (ii) the material facts as to his relationship or interest and as to the
contract or transaction are disclosed or are known to the stockholders entitled
to vote thereon, and the contract or transaction is specifically approved in
good faith by vote of the stockholders or (iii) the contract or transaction is
fair as to the Corporation as of the time it is authorized, approved or ratified
by the Board of Directors, a committee thereof or the stockholders. Common or
interested directors may be counted in determining the presence of a quorum at a
meeting of the Board of Directors or of a committee that authorizes the contract
or transaction.

         Section 13. Committees. The Board of Directors may, by resolution
passed by a majority of the entire Board, designate committees, each committee
to consist of two or more Directors of the Corporation, which committees will
have such power and authority and will perform such functions as may be provided
in such resolution. Such committee or committees will have such name or names as
may be designated by the Board and will keep regular minutes of their
proceedings and report the same to the Board of Directors when required.

         Section 14. Action by Consent. Any action required or permitted to be
taken at any meeting of the Board of Directors or any committee of the Board of
Directors may be taken without such a meeting if a consent or consents in
writing, setting forth the action so taken, is signed by all the members of the
Board of Directors or such committee, as the case may be.

         Section 15. Compensation of Directors. Directors will receive such
compensation for their services and reimbursement for their expenses as the
Board of Directors, by resolution, may establish; provided that nothing herein

                                   ARTICLE IV

                                     NOTICE

         Section 1. Form of Notice. Whenever by law, the Certificate of
Incorporation or of these Bylaws, notice is to be given to any Director or
stockholder, and no provision is made as to how such notice will be given, such
notice may be given in writing, by mail, postage prepaid, addressed to such
Director or stockholder at such address as appears on the books of the
Corporation. Any notice required or permitted to be given by mail will be deemed
to be given at the time the same is deposited in the United States mails.


         Section 2. Waiver. Whenever any notice is required to be given to any
stockholder or Director of the Corporation as required by law, the Certificate
of Incorporation or these Bylaws, a

                                       -6-
<PAGE>   10


waiver thereof in writing signed by the person or persons entitled to such
notice, whether before or after the time stated in such notice, will be
equivalent to the giving of such notice. Attendance of a stockholder or Director
at a meeting will constitute a waiver of notice of such meeting, except where
such stockholder or Director attends for the express purpose of objecting, at
the beginning of the meeting, to the transaction of any business on the ground
that the meeting has not been lawfully called or convened.

                                    ARTICLE V

                               OFFICERS AND AGENTS

         Section 1. In General. The officers of the Corporation will be elected

Secretaries and Assistant Treasurers. Any two or more offices may be held by the
same person.

         Section 2. Election. The Board of Directors, at its first meeting after
each annual meeting of stockholders, will elect the officers, none of whom need

         Section 3. Other Officers and Agents. The Board of Directors may also
elect and appoint such other officers and agents as it deems necessary, who will
be elected and appointed for such terms and will exercise such powers and
perform such duties as may be determined from time to time by the Board.

         Section 4. Compensation. The compensation of all officers and agents of

election and qualification of his successor, whichever occurs first. Any officer
or agent elected or appointed by the Board of Directors may be removed at any
time, for or without cause, by the affirmative vote of a majority of the entire
Board of Directors, but such removal will not prejudice the contract rights, if
any, of the person so removed. If the office of any officer becomes vacant for
any reason, the vacancy may be filled by the Board of Directors.

         Section 6. Employment and Other Contracts. The Board of Directors may
authorize any officer or officers or agent or agents to enter into any contract
or execute and deliver any instrument in the name or on behalf of the
Corporation, and such authority may be general or confined to specific
instances. The Board of Directors may, when it believes the interest of the
Corporation will best be served thereby, authorize executive employment
contracts that will have terms no longer than ten years and contain such other
terms and conditions as the Board of Directors deems appropriate.

Corporation. During the absence or disability of the President, the Chairman
will exercise the powers and perform the duties of the President.

         Section 8. President. The President will be the chief executive officer
of the Corporation and, subject to the control of the Board of Directors, will
supervise and control all of the business and affairs of the Corporation. He
will, in the absence of the Chairman of the Board, preside at all meetings of
the stockholders and the Board of Directors. The President will have all powers
and perform all duties incident to the office of President and will have such
other powers and perform such other duties as the Board of Directors may from
time to time prescribe.

         Section 9. Vice Presidents. Each Vice President will have the usual and
customary powers and perform the usual and customary duties incident to the
office of Vice President, and will have such other powers and perform such other
duties as the Board of Directors or any committee thereof may from time to time
prescribe or as the President may from time to time delegate to him. In the
absence or disability of the President and the Chairman of the Board, a Vice
President designated by the Board of Directors, or in the absence of such
designation the Vice Presidents in the order of their seniority in office, will
exercise the powers and perform the duties of the President.

         Section 10. Secretary. The Secretary will attend all meetings of the
stockholders and record all votes and the minutes of all proceedings in a book
to be kept for that purpose. The Secretary will perform like duties for the
Board of Directors and committees thereof when required. The Secretary will
give, or cause to be given, notice of all meetings of the stockholders and
special meetings of the Board of Directors. The Secretary will keep in safe
custody the seal of the Corporation. The Secretary will be under the supervision
of the President. The Secretary will have such other powers and perform such
other duties as the Board of Directors may from time to time prescribe or as the
President may from time to time delegate to him.

         Section 11. Assistant Secretaries. The Assistant Secretaries in the
order of their seniority in office, unless otherwise determined by the Board of
Directors, will, in the absence or disability of the Secretary, exercise the
powers and perform the duties of the Secretary. They will have such other powers
and perform such other duties as the Board of Directors may from time to time
prescribe or as the President may from time to time delegate to them.

         Section 12. Treasurer. The Treasurer will have responsibility for the
receipt and disbursement of all corporate funds and securities, will keep full
and accurate accounts of such receipts and disbursements, and will deposit or
cause to be deposited all moneys and other valuable

                                       -8-

<PAGE>   12


effects in the name and to the credit of the Corporation in such depositories as
may be designated by the Board of Directors. The Treasurer will render to the
Directors whenever they may require it an account of the operating results and
financial condition of the Corporation, and will have such other powers and
perform such other duties as the Board of Directors may from time to time
prescribe or as the President may from time to time delegate to him.

         Section 13. Assistant Treasurers. The Assistant Treasurers in the order

         Section 14. Bonding. The Corporation may secure a bond to protect the
Corporation from loss in the event of defalcation by any of the officers, which
bond may be in such form and amount and with such surety as the Board of
Directors may deem appropriate.

                                   ARTICLE VI

                        CERTIFICATES REPRESENTING SHARES

         Section 1. Form of Certificates. Certificates, in such form as may be
determined by the Board of Directors, representing shares to which stockholders
are entitled will be delivered to each stockholder. Such certificates will be
consecutively numbered and will be entered in the stock book of the Corporation
as they are issued. Each certificate will state on the face thereof the holder's
name, the number, class of shares, and the par value of such shares or a
statement that such shares are without par value. They will be signed by the
President or a Vice President and the Secretary or an Assistant Secretary, and
may be sealed with the seal of the Corporation or a facsimile thereof. If any
certificate is countersigned by a transfer agent, or an assistant transfer agent
or registered by a registrar, either of which is other than the Corporation or
an employee of the Corporation, the signatures of the Corporation's officers may
be facsimiles. In case any officer or officers who have signed, or whose
facsimile signature or signatures have been used on such certificate or
certificates, ceases to be such officer or officers of the Corporation, whether
because of death, resignation or otherwise, before such certificate or
certificates have been delivered by the Corporation or its agents, such
certificate or certificates may nevertheless be adopted by the Corporation and
be issued and delivered as though the person or persons who signed such
certificate or certificates or whose facsimile signature or signatures have been
used thereon had not ceased to be such officer or officers of the Corporation.

         Section 2. Lost Certificates. The Board of Directors may direct that a
new certificate be issued in place of any certificate theretofore issued by the
Corporation alleged to have been lost or destroyed, upon the making of an
affidavit of that fact by the person claiming the certificate to be lost or
destroyed. When authorizing such issue of a new certificate, the Board of
Directors, in its discretion and as a condition precedent to the issuance
thereof, may require the owner of such lost

                                       -9-

<PAGE>   13


or destroyed certificate, or his legal representative, to advertise the same in
such manner as it may require and/or to give the Corporation a bond, in such
form, in such sum, and with such surety or sureties as it may direct as
indemnity against any claim that may be made against the Corporation with
respect to the certificate alleged to have been lost or destroyed. When a
certificate has been lost, apparently destroyed or wrongfully taken, and the
holder of record fails to notify the Corporation within a reasonable time after
such holder has notice of it, and the Corporation registers a transfer of the
shares represented by the certificate before receiving such notification, the
holder of record is precluded from making any claim against the Corporation for
the transfer of a new certificate.

         Section 3. Transfer of Shares. Shares of stock will be transferable
only on the books of the Corporation by the holder thereof in person or by such
holder's duly authorized attorney. Upon surrender to the Corporation or the
transfer agent of the Corporation of a certificate representing shares duly
endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, it will be the duty of the Corporation or the transfer
agent of the Corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.

         Section 4. Registered Stockholders. The Corporation will be entitled to
treat the holder of record of any share or shares of stock as the holder in fact
thereof and, accordingly, will not be bound to recognize any equitable or other
claim to or interest in such share or shares on the part of any other person,
whether or not it has express or other notice thereof, except as otherwise
provided by law.

                                   ARTICLE VII

                               GENERAL PROVISIONS

         Section 1. Dividends. Dividends upon the outstanding shares of the
Corporation, subject to the provisions of the Certificate of Incorporation, if
any, may be declared by the Board of Directors at any regular or special
meeting. Dividends may be declared and paid in cash, in property, or in shares
of the Corporation, subject to the provisions of the General Corporation Law of
the State of Delaware and the Certificate of Incorporation. The Board of
Directors may fix in advance a record date for the purpose of determining
stockholders entitled to receive payment of any dividend, such record date will
not precede the date upon which the resolution fixing the record date is
adopted, and such record date will not be more than sixty days prior to the
payment date of such dividend. In the absence of any action by the Board of
Directors, the close of business on the date upon which the Board of Directors
adopts the resolution declaring such dividend will be the record date.

         Section 2. Reserves. There may be created by resolution of the Board of
Directors out of the surplus of the Corporation such reserve or reserves as the
Directors from time to time, in their discretion, deem proper to provide for
contingencies, or to equalize dividends, or to repair or

                                      -10-

<PAGE>   14


maintain any property of the Corporation, or for such other purpose as the
Directors may deem beneficial to the Corporation, and the Directors may modify
or abolish any such reserve in the manner in which it was created. Surplus of
the Corporation to the extent so reserved will not be available for the payment
of dividends or other distributions by the Corporation.

         Section 3. Telephone and Similar Meetings. Stockholders, directors and
committee members may participate in and hold meetings by means of conference
telephone or similar communications equipment by which all persons participating
in the meeting can hear each other. Participation in such a meeting will
constitute presence in person at the meeting, except where a person participates
in the meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business on the ground that the meeting has
not been lawfully called or convened.

         Section 4. Books and Records. The Corporation will keep correct and
complete books and records of account and minutes of the proceedings of its
stockholders and Board of Directors, and will keep at its registered office or
principal place of business, or at the office of its transfer agent or
registrar, a record of its stockholders, giving the names and addresses of all
stockholders and the number and class of the shares held by each.

         Section 5. Fiscal Year. The fiscal year of the Corporation will be
fixed by resolution of the Board of Directors.

         Section 6. Seal. The Corporation may have a seal, and the seal may be
used by causing it or a facsimile thereof to be impressed or affixed or
reproduced or otherwise. Any officer of the Corporation will have authority to
affix the seal to any document requiring it.

         Section 7. Advances of Expenses. The Corporation will advance to its
directors and officers expenses incurred by them in connection with any
"Proceeding," which term includes any threatened, pending or completed action,
suit or proceeding, whether brought by or in the right of the Corporation or
otherwise and whether of a civil, criminal, administrative or investigative
nature (including all appeals therefrom), in which a director or officer may be
or may have been involved as a party or otherwise, by reason of the fact that he
is or was a director or officer of the Corporation, by reason of any action
taken by him or of any inaction on his part while acting as such, or by reason
of the fact that he is or was serving at the request of the Corporation as a
director, officer, trustee, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise
("Official," which term also includes directors and officers of the Corporation
in their capacities as directors and officers of the Corporation), whether or
not he is serving in such capacity at the time any liability or expense is
incurred; provided that the Official undertakes to repay all amounts advanced
unless:


                  (i) in the case of all Proceedings other than a Proceeding by
         or in the right of the Corporation, the Official establishes to the
         satisfaction of the disinterested members of the Board of Directors
         that he acted in good faith or in a manner he

                                      -11-

<PAGE>   15


         reasonably believed to be in or not opposed to the best interests of
         the Corporation and, with respect to any criminal proceeding, that he
         did not have reasonable cause to believe his conduct was unlawful;
         provided that the termination of any such Proceeding by judgment, order
         of court, settlement, conviction, or upon a plea of nolo contendere or
         its equivalent, shall not by itself create a presumption as to whether
         the Official acted in good faith or in a manner he reasonably believed
         to be in or not opposed to the best interests of the Corporation or,
         with respect to any criminal proceeding, as to whether he had
         reasonable cause to believe his conduct was unlawful; or

                  (ii) in the case of a Proceeding by or in the right of the
         Corporation, the Official establishes to the satisfaction of the
         disinterested members of the Board of Directors that he acted in good
         faith or in a manner he reasonably believed to be in or not opposed to
         the best interests of the Corporation; provided that if in such a
         Proceeding the Official is adjudged to be liable to the Corporation,
         all amounts advanced to the Official for expenses must be repaid except
         to the extent that the court in which such adjudication was made shall
         determine upon application that despite such adjudication, in view of
         all the circumstances, the Official is fairly and reasonably entitled
         to indemnity for such expenses as the court may deem proper.

         Section 8. Indemnification. The Corporation will indemnify its
directors to the fullest extent permitted by the General Corporation Law of the
State of Delaware and may, if and to the extent authorized by the Board of
Directors, so indemnify its officers and any other person whom it has the power
to indemnify against any liability, reasonable expense or other matter
whatsoever.

         Section 9. Insurance. The Corporation may at the discretion of the
Board of Directors purchase and maintain insurance on behalf of the Corporation
and any person whom it has the power to indemnify pursuant to law, the
Certificate of Incorporation, these Bylaws or otherwise.

         Section 10. Resignation. Any director, officer or agent may resign by
giving written notice to the President or the Secretary. Such resignation will
take effect at the time specified therein or immediately if no time is specified
therein. Unless otherwise specified therein, the acceptance of such resignation
will not be necessary to make it effective.

         Section 11. Amendment of Bylaws. These Bylaws may be altered, amended,
or repealed at any meeting of the Board of Directors at which a quorum is
present, by the affirmative vote of a majority of the Directors present at such
meeting.

         Section 12. Invalid Provisions. If any part of these Bylaws is held
invalid or inoperative for any reason, the remaining parts, so far as possible
and reasonable, will be valid and operative.

         Section 13. Relation to the Certificate of Incorporation. These Bylaws

Corporation.

$________________                                  ______________________, 1996


         FOR VALUE RECEIVED, the undersigned, Electronics Accessory Specialists
International, Inc., a Delaware corporation ("Maker"), hereby promises to pay
to the order of ____________________________ ("Payee"), the principal sum of
____________________ ($____________), together with interest thereon which
shall accrue at a rate equal to twelve percent (12%) per annum. The interest on
this Debenture shall be due and payable on March 31, June 30, September 30 and
December 31 of each year (the "Quarterly Payment Dates"), commencing on
_____________ and continuing until the Debenture has been paid in full. The
principal, together with all accrued but unpaid interest hereon shall be due
and payable in twenty (20) equal quarterly installments on each of the
Quarterly Payment Dates, beginning on the second anniversary of the date hereof
with the final payment being due and payable on ________. All payments on this
Debenture shall be due and payable in lawful money of the United States of
America.

THIS DEBENTURE IS ONE DEBENTURE OF A SERIES OF DEBENTURES OF EVEN DATE
HEREWITH.

         1. Prepayments. Subject to the conversion rights set forth in
paragraph 3 below, at the option of Maker, the unpaid principal balance of this
Debenture may be prepaid in whole together with all accrued but unpaid interest
at any time upon thirty (30) days notice to Payee.

         2. IPO Redemption Option. Unless prepaid by Maker as provided herein,
at the option of the holder of this Debenture (the "IPO Redemption Option"),
this Debenture will be redeemed, in whole or in part, at the closing (the
"Closing") of an initial public offering (the "IPO") of the Maker's common
stock, par value $0.01 per share (the "Common Stock"). Maker shall give written
notice to the holder of this Debenture at least thirty (30) days prior to the
date of Closing (the "Closing Date"). The redemption shall be made at the
redemption price equal to 100% of the principal amount of the Debentures to be
redeemed, plus accrued interest, if any, to the date of the Closing; provided
that the IPO Redemption Option will terminate at the close of business on the
Closing Date and will be lost if not exercised at that time. The IPO Redemption
Option may be exercised separately or in conjunction with the conversion right
set forth in paragraph 3 of this Debenture.

         3. Conversion.

                  (a) Unless prepaid by Maker as provided herein, sixty percent
         (60%) of the outstanding principal balance of this Debenture is
         convertible, at the option of the holder of this Debenture, into
         Common Stock on the Closing Date at the rate of one share of Common
         Stock for each $170.00 of principal of this Debenture (but just the
         sixty percent (60%) convertible portion thereof); provided, however,
         that to the extent that the equity/debt financing pursuant to which
         this Debenture was issued is finished at a price for the equity of
         less than $170 per share, then the $170 conversion price shall be
         adjusted downward to such lower price; provided further, however, that
         the right to convert the Debenture will terminate at the close of
         business on the Closing Date and will be lost if not exercised prior
         to that time.

                  (b) In order to exercise the conversion privilege, the holder
         of this Debenture shall: (i) surrender this Debenture to Maker with
         the form for conversion the form of which is attached hereto as
         Exhibit A, duly executed; and (ii) execute and deliver to Maker a
         signature page to the Stockholders Agreement of the Company, as may be
         amended from time to time (the "Stockholders Agreement"), in the form
         attached hereto as Exhibit B, no sooner than twenty (20) days and no
         later than five (5) days prior to the proposed Closing Date. If the
         Common Stock into which this Debenture is convertible is to be issued
         in a name or names other than that of Payee, the Debenture must be
         accompanied by proper assignment. If the Debenture is not prepaid
         prior to the Closing Date, Maker will promptly after the Closing Date
         issue to the holder of the Debenture the shares of Common Stock into
         which this Debenture is convertible. Maker shall furnish to the holder
         of this Debenture, upon written request, a copy of the Stockholders
         Agreement.

         4. Events of Default and Remedies. At the option of the holder of this
Debenture, the entire amount of the unpaid balance of this Debenture, shall
immediately become due and payable upon the occurrence of one or more of the
following events of default ("Events of Default"):

                  (a) Failure of Maker to make any payment on this Debenture as
         and when the same becomes due and payable in accordance with the terms
         hereof, and such failure continues for a period of (30) days after the
         receipt by Maker of written notice from Payee of the occurrence of
         such failure; or

                  (b) Maker shall (i) become insolvent, (ii) voluntarily seek,
         consent to or acquiesce in the benefit or benefits of any Debtor
         Relief Law (as hereinafter defined) or (iii) become party to (or be
         made the subject of) any proceeding provided by any Debtor Relief Law,
         other than as a creditor or claimant, that could suspend or otherwise
         adversely affect the rights of Payee granted hereunder (unless in the
         event such proceeding is involuntary, the petition instituting the
         same is dismissed within 90 days of the filing of same). As used
         herein, the term "Debtor Relief Law" means the Bankruptcy Code of the
         United States of America and all other applicable liquidation,
         conservatorship, bankruptcy, moratorium, rearrangement, receivership,
         insolvency, reorganization or similar debtor relief laws from time to
         time in effect affecting the rights of creditors generally.

         In the event any one or more of the Events of Default specified above
shall have happened, the holder of this Debenture may proceed to protect and
enforce its rights either by suit in equity or by action at law, or by other
appropriate proceedings, whether for the specific performance of any covenant
or agreement contained in this Debenture or in aid of the exercise of any power
or right granted by this Debenture, or to enforce any other legal or equitable
right of the holder of this Debenture.

         5. Cumulative Rights. No delay on the part of the holder of this
Debenture in the exercise of any power or right under this Debenture, or under
any other instrument executed pursuant hereto, shall operate as a waiver
thereof, nor shall a single or partial exercise of any such power or right
preclude any other or further exercise thereof or the exercise of any other
right or power hereunder. Enforcement by the holder of this Debenture of any
security for the payment hereof shall not constitute any election by it of
remedies so as to preclude the exercise of any other remedy available to it.

         6. Waiver. Except as otherwise specifically provided for herein,
Maker, and each security, endorser, guarantor and other party ever liable for
the payment of any sum of money payable on this Debenture, jointly and
severally waive demand, presentment, protest, notice of non-payment, notice of
intention to accelerate, notice of protest and any and all lack of diligence or
delay in collection or the filing of suit hereon which may occur, and agree
that their liability on this Debenture shall not be affected by any renewal or
extension in the time of payment hereof, by any indulgences, or by any release
or change in any security for the payment of this Debenture; and hereby consent
in any and all renewals, extensions, indulgences, releases or changes,
regardless of the number of such renewals, extensions, indulgences, releases or
changes.

         7. Subordination. Notwithstanding anything herein to the contrary, the
payment of principal and interest on this Debenture shall be subordinate and
junior to the prior payment of the indebtedness of Maker now existing or
hereafter created constituting borrowed money from financial institutions or
lenders approved by the Board of Directors of Maker and designated as being
senior to this Debenture (but only to the extent so designated), together with
all obligations issued in renewal, deferral, extension, refunding, amendment or
modification of any such indebtedness (collectively, the "Senior
Indebtedness"). Accordingly, as a condition of accepting this Debenture, the
holder of this Debenture hereby irrevocably appoints the officers of Maker, or
any of them, as its power-of-attorney to execute and deliver any subordination
agreement required by any holder of Senior Indebtedness. If any payment or
distribution shall be received in respect of this Debenture in contravention of
the terms of this Section 7, such payment or distribution shall be held in
trust for the holders of the Senior Indebtedness, and shall be immediately
delivered to such holders in the same form as received.

         8. Attorneys' Fees and Costs. In the event an Event of Default shall
occur, and in the event that thereafter this Debenture is placed in the hands
of any attorney for collection, or in the event this Debenture is collected in
whole or in part through legal proceedings of any nature, then and in any such
case Maker promises to pay all costs of collection, including, but not limited
to, reasonable attorneys' fees and court costs incurred by the holder hereof on
account of such collection, whether or not suit is filed.

                                       3
<PAGE>   4

         9. Successors and Assigns. All of the covenants, stipulations,
promises and agreements in this Debenture made by or on behalf of Maker shall
bind its successors and assigns, whether so expressed or not; provided,
however, that Maker may not, without the prior written consent of Payee, assign
any of its rights, powers, duties or obligations under this Debenture.

         10. Maximum Interest. Regardless of any provision contained herein,
Maker shall never be required to pay and the holder hereof shall never be
entitled to receive, collect or apply as interest hereon, any amount in excess
of the highest lawful interest rate permitted under applicable law, and in the
event the holder hereof receives, collects or applies, as interest, any such
excess, such amounts which would be excessive interest shall be deemed a
partial prepayment of principal and treated hereunder as such for all purposes;
and, if the principal hereof is paid in full, any remaining excess shall be
refunded to Maker. In determining whether or not the interest paid or payable,
under any specific contingency, exceeds the highest lawful interest rate, Maker
and the holder hereof shall, to the maximum extent permitted under applicable
law (a) characterize any nonprincipal payment as an expense, fee or premium
rather than as interest, (b) exclude prepayments and the effects thereof, and
(c) pro rate, allocate and spread the total amount of interest throughout the
entire contemplated term hereof; provided that if the indebtedness evidenced
hereby is paid and performed in full prior to the end of the full contemplated
term hereof, and if the interest received for the actual period of existence
thereof exceeds the highest lawful interest rate, the holder shall either apply
as principal reduction or refund to Maker the amount of such excess, and in
such event, the holder shall not be subject to any penalties provided by any
laws for contracting for, charging or receiving interest in excess of the
highest lawful interest rate.

         11. Restrictions on Transferability. By taking this Debenture, the
Payee hereof acknowledges that (a) this Debenture has been acquired for
investment and has not been registered under the Securities Act of 1933, as
amended (the "Securities Act") or any state securities act, (b) this Debenture
must be held indefinitely unless subsequent disposition thereof is registered
under the Securities Act and all applicable state securities laws or unless an
exemption from such registration is available, or unless the Maker receives an
opinion of counsel, or other evidence, reasonably satisfactory to Maker stating
that such disposition is made in compliance with an exemption from such
registration, and prospectus delivery requirements, (c) Maker hereby informs
Payee that it has made a notation on its transfer books to such effect; and (d)
that the shares of Common Stock underlying this Debenture will be acquired for
investment and have not been registered under the Securities Act or any state
securities act, and are subject to restrictions as provided in such laws and as
provided in the Stockholders Agreement.

         12. Governing Law. This Debenture shall be governed by and construed
in accordance with the substantive laws (but not the rules governing conflicts
of laws) of the State of Delaware.

         13. Notice. Any notice or demand given hereunder by the holder hereof
shall be deemed to have been given and received (a) when actually received by
Maker, if delivered in person, or (b) if mailed, on the earlier of the date
actually received or (whether ever received or not) three Business Days (as
hereinafter defined) after a letter containing such notice, certified or
registered with postage prepaid, addressed to Maker, is deposited in the United
States mail. The address of

                                       4
<PAGE>   5

Maker is 5528 Eubank Boulevard, N.E., Suite 3, Albuquerque, New Mexico 87111,
or such other address as Maker shall advise the holder hereof by certified or
registered letter by this same procedure. "Business Day" means every day which
is not a Saturday, Sunday or legal holiday.

         14. Severability. In case any one or more of the provisions contained
in this Debenture shall for any reason be held to be invalid, illegal and
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision hereof.

         EXECUTED as of the date set forth above.

                          REGISTRATION RIGHTS AGREEMENT

         This Registration Rights Agreement (this "Agreement"), dated as of July
29, 1997, is by and between Electronics Accessory Specialists International,

                              W I T N E S S E T H:

         WHEREAS, the Purchaser and Securityholder have entered an Asset
Purchase Agreement, of even date herewith (the "Purchase Agreement"), pursuant
to which, among other things, the Purchaser has agreed, upon the occurrence of
certain conditions, to issue to the Securityholder the Shares; and

         WHEREAS, in order to induce the Securityholder to enter into the
Purchase Agreement, Purchaser has agreed to provide registration rights with
respect to the Shares;

hereinafter contained, it is agreed as follows:

<PAGE>   2



SECTION 2. REGISTRATIONS.

         2.1 Registration Securities. As used in this Agreement, the term
"Registration Securities" means (i) the Shares and (ii) any other securities
issued, from time to time, in respect of or in exchange for any Shares by way of
a stock dividend or other distribution on the Common Stock, stock split or in
connection with a combination of shares, recapitalization, merger,
consolidation, reclassification or exchange offer; provided, however, that such
Registration Securities shall cease to be Registration Securities when (i) they
have been registered under the Securities Act, the registration statement in
connection therewith has been declared effective, and such shares have been
disposed of by the holder of such shares pursuant to such registration statement
or (ii) such shares have ceased to be outstanding.

         2.2 Piggyback Registration.

                  (a) If at any time after Purchaser becomes a Reporting
Company, Purchaser proposes to file a registration statement under the
Securities Act covering a proposed sale of any Common Stock, for itself (other
than a registration statement on Form S-4 or S-8, or any form substituting
therefor for securities to be offered in a transaction of the type referred to
in Rule 145 under the Securities Act or to employees of Purchaser pursuant to
any employee benefit plan, respectively), or for anyone else (i.e., a secondary
offering) Purchaser shall give each holder who then holds, beneficially and of
record, Registration Securities written notice of such proposed filing at least
30 days prior to the anticipated filing date, and such notice shall offer each
such holder the opportunity to register such number of shares of Registration
Securities as they may request, subject to such holder's accepting the terms of
the underwriting, including the public offering price and underwriting discounts
and commissions, as agreed upon between Purchaser and the managing underwriter
selected by it; and such holder shall have 10 days after the date of such notice
to notify Purchaser in writing as to whether or not such holder desires to
participate in such offering. Purchaser shall use its best efforts to cause any
managing underwriter of a proposed underwritten offering to permit such holders
to include such Registration Securities as they may propose be included in such
offering on the same terms and conditions as any similar securities of Purchaser
included therein.

                  (b) Notwithstanding anything in this Section 2.2 to the
contrary: (i) no such registration hereunder shall be required if the managing
underwriter for the proposed offering shall determine that the inclusion of the
Registration Securities requested to be registered would have an adverse effect
on the marketability or the price of the securities proposed to be offered by
Purchaser, in which event Purchaser shall be obligated to include only such
limited number, if any, of Registration Securities in such offering as the
managing underwriter believes may be sold without causing such adverse effect,
which securities will be taken from those held by a group consisting of the
holders proposing to sell Registration Securities and other holders of
securities of Purchaser having similar registration rights to those of the
holders, on a pro rata basis and (ii) Purchaser may at any time withdraw or
cease proceeding with the registration of such Registration Securities if it
shall at the time withdraw or cease proceeding with the



                                      -2-
<PAGE>   3

registration of such other securities originally proposed to be registered
without obligation to any holder seeking to include Registration Securities
therein (except the obligation to pay expenses under Section 2.5). In the event
that the contemplated registration does not involve an underwritten public
offering, the determination that the inclusion of such Registration Securities
would have an adverse effect on the marketability or the price of the securities
proposed to be offered by Purchaser shall be made by Purchaser in its reasonable
discretion.

         2.3 Further Obligations of Purchaser. Whenever, under this Agreement,
Purchaser is required to register Registration Securities, it agrees that it
shall also do the following:

                  (a) prepare and file with the SEC a registration statement
with respect to such securities and use its best efforts to cause such
registration statement to become effective at the earliest practicable time and
remain effective;

                  (b) prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
current;

                  (c) furnish to each holder offering Registration Securities
under such registration statement such number of copies of a prospectus,
including a preliminary prospectus complying with the requirements of the
Securities Act, as such holder may reasonably request and such other documents
as such seller may reasonably request to facilitate the public sale of such
Registration Securities;

                  (d) use all reasonable efforts to register or qualify the
securities covered by such registration statement under the securities or blue
sky laws of such states within the United States as the underwriter or manager
shall request or in the event that the registration does not involve an
underwritten public offering as each such holder shall reasonably request;
provided, however, that Purchaser shall not be obligated to register or qualify
such securities in any jurisdiction in which such registration or qualification
would require Purchaser to qualify as a foreign corporation or file any general
consent to service of process where it is not then so qualified or otherwise
required to be qualified or has not theretofore so consented;

                  (e) subject to the other provisions of this Agreement, enter
into customary agreements (including an underwriting agreement in customary form
in the case of an underwritten public offering) and take such other actions as
are reasonably required in order to expedite or facilitate the disposition of
such Registration Securities;

                  (f) promptly notify each seller of Registration Securities
covered by such registration statement and each underwriter under such
registration statement, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, upon discovery that, or upon
the happening of any event as a result of which, the prospectus included in such
registration statement, as then in effect, contains an untrue statement of a
material fact or omits



                                      -3-
<PAGE>   4

to state any material fact required to be stated therein or necessary to make
the statements therein not misleading in light of the circumstances under which
they were made, and at the request of any such seller or holder promptly prepare
and furnish to such seller or holder a reasonable number of copies of a
supplement to or an amendment of such prospectus as may be necessary so that, as
thereafter delivered to the purchasers of such securities, such prospectus shall
not include an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances under which they were made;

                  (g) furnish to each holder of Registration Securities
participating in the offering and to each underwriter, if any, (i) an opinion of
counsel to the Purchaser, dated the effective date of such registration
statement (or, if such registration includes an underwritten public offering, an
opinion dated the date of the closing under the underwriting agreement) and (ii)
in the case of an underwritten public offering, a "cold comfort" letter dated
the date of the closing under the underwriting agreement signed by the
independent public accountants who have issued a report on the Purchaser's
financial statements included in such registration statement, in each case
covering substantially the same matters with respect to such registrations (and
the prospectus included therein) and in the case of such accountant's letter,
with respect to events subsequent to the date of such financial statements, as
are customarily covered in opinions of issuer's counsel and in accountants'
letters delivered to underwriters in underwritten public offerings of
securities;

                  (h) otherwise comply with all applicable rules and regulations
of the SEC, and make generally available to its security holders (within the
meaning of Rule 158 under the Securities Act), as soon as reasonably practicable
after the effective date of the registration statement, and in any event within
15 months thereafter, an earnings statement, which need not be audited, covering
the period of at least 12 months, but not more than 15 months, beginning with
the first full calendar month after the effective date of such registration
statement, which earnings statement shall satisfy the provisions of Section
11(a) of the Securities Act, and will furnish to each such seller at least five
business days prior to the filing thereof a copy of any amendment or supplement
to such registration statement or prospectus; and

                  (i) promptly furnish each holder offering Registration
Securities under such registration statement notice of the issuance of any stop
order suspending the effectiveness of such registration statement.

         2.4 Holdback Agreement. If any registration in which any holder of
Registration Securities is participating shall be in connection with an
underwritten public offering, each such holder agrees, if requested by the
managing underwriter or underwriters, to the extent permitted by law, not to
effect any public sale or distribution, including any sale pursuant to Rule 144
under the Securities Act, of any Registration Securities, and to use such
holder's best efforts not to effect any such public sale or distribution of any
equity security of Purchaser or of any security convertible into or exchangeable
or exercisable for any equity security, of Purchaser (in each case, other than
as part of such underwritten public offering) within 10 days before or 90 days
after the



                                      -4-
<PAGE>   5

effective date of such registration. If requested by the managing underwriter in
any such registration, Purchaser shall cause the directors and executive
officers of Purchaser to execute and deliver similar holdback agreements.

         2.5 Expenses. All expenses incurred in complying with this Agreement,
including, without limitation, all registration and filing fees (including all
expenses incident to filing with the NASD), printing expenses, fees and
disbursements of counsel for Purchaser, expenses of any special audits incident
to or required by any such registration and expenses of complying with the
securities or blue sky laws of any jurisdictions pursuant to Section 2.5(d),
shall be paid by Purchaser, except that Purchaser shall not be liable for any
underwriting discounts or commissions or transfer taxes on shares being sold by
such holder of Registration Securities or for any fees or expenses of any
attorney of any such holder.

         It shall be a condition precedent to the obligation of Purchaser to
take any action pursuant to this Agreement in respect of the securities that are
to be registered at the request of any holder of Registration Securities that
such holder shall furnish to Purchaser such information regarding such holder
and the Registration Securities held by such holder as Purchaser shall
reasonably request and shall be required in connection with the action taken by
Purchaser.

         2.6 Indemnification; Notice of Claims.

                  (a) Subject to applicable law, Purchaser will indemnify each
underwriter and the holders of Registration Securities and each of their
respective officers, directors, partners, controlled or controlling persons
against all claims, losses, damages and liabilities, including legal and other
expenses reasonably incurred, arising out of any untrue or allegedly untrue
statement of a material fact (including those incurred in connection with
investigating or defending such claim) contained in the registration statement,
any preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto or any other document, or any
omission to state a material fact required to be stated therein or necessary to
make the statements not misleading, or arising out of any violation by Purchaser
of the Securities Act, any state securities or "blue sky" laws or any applicable
rule or regulation. This indemnification will not apply to any claims, losses,
damages or liabilities if and to the extent they may have been caused by an
untrue statement or omission based upon information furnished in writing to
Purchaser by, and pertaining to, such underwriter, holder of Registration
Securities, or their respective officers, directors, partners, controlled or
controlling persons, expressly for use in the registration statement. With
respect to such untrue statement or omission in the information furnished in
writing to Purchaser by any holder of Registration Securities, such holder will
indemnify the underwriters, Purchaser, its directors and officers, the other
persons selling securities under the registration statement and each person
controlling any of them against any losses, claims, damages, expenses or
liabilities to which any of them may become subject as a result of such untrue
statement or omission (including those incurred in connection with investigating
or defending against such claims). The rights of indemnification under this
Section 2.6 shall be in addition to any other rights to indemnification that the
holders of Registration



                                      -5-
<PAGE>   6

Securities may have by law, contract or otherwise.

                  (b) Promptly after receipt by an indemnified party of notice
of the commencement of any action or proceeding involving a claim referred to in
this Section 2.6, such indemnified party will, if a claim in respect thereof is
to be made against an indemnifying party, promptly give written notice to the
latter of the commencement of such action, provided that the failure of any
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its obligations under this Section 2.6, except and to the
extent that the indemnifying party is prejudiced by such failure to give notice.

         2.7 Termination of Agreement and Certain Rights. This Agreement and the
rights of any holder of Registration Securities to cause Purchaser to file a
registration statement under this Agreement above shall terminate upon the
earlier of: (a) the sale of all or substantially all of the assets of Purchaser
or the merger of Purchaser with and into another business entity; or (b)
December 31, 2000.

SECTION 3. MISCELLANEOUS

         3.1 Remedies. Each holder of Registration Securities, in addition to
being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this
Agreement. Purchaser agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions
of this Agreement and hereby agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate. In any action or
proceeding brought to enforce any provision of this Agreement or where any
provision hereof is validly asserted as a defense, the successful party shall be
entitled to recover reasonable attorneys' fees in addition to any other
available remedy.

         3.2 Amendments and Waivers. Except as otherwise provided herein, the
provisions of this Agreement may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given
unless Purchaser has obtained the written consent of holders of at least a
majority of the Registration Securities then outstanding.

         3.3 Notice Generally. Any notice, demand, request, consent, approval,
declaration, delivery or other communication hereunder to be made pursuant to
the provisions of this Agreement shall be sufficiently given or made if done in
accordance with Section 9.8 of the Purchase Agreement.

         3.4 Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns of each of the parties hereto
to the extent Registration Securities have been transferred to such successors
or assigns and provided that such successor or assign executes and delivers to
Purchaser a signature page, in the form of Exhibit A attached hereto.

         3.5 Headings. The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

         3.6 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE
STATE OF DELAWARE, WITHOUT REGARD TO PROVISIONS THEREOF RELATING TO CONFLICT OF
LAWS.

         3.7 Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision on this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Agreement.

         3.8 Entire Agreement. This Agreement is intended by the parties as a
final expression of their agreement and intended to be a complete exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. This Agreement (including the exhibits
hereto) supersede all prior agreements and understandings between the parties
with respect to such subject matter.

                        FORM OF UNIT PURCHASE AGREEMENT



         ELECTRONICS ACCESSORY SPECIALISTS INTERNATIONAL, INC., a Delaware
corporation (the "Company"), whose address is 7955 East Redfield Road,
Scottsdale, Arizona 85260, hereby agrees with the undersigned Purchaser as
follows:

1.       TRANSACTION

         The Company, by due action of its Board of Directors, has authorized
the offer and sale to you under this Unit Purchase Agreement ("Agreement" or
"Purchase Agreement") and to other purchasers under similar Purchase Agreements
("Other Purchasers") of up to 900 Units (1,210 if the Company's over-allotment
option is exercised in full), each consisting of 1,000 shares of common stock,
par value $ .01 per share ("Common Stock"), of the Company ("Common Shares").
The Unit price shall be $5,750 and no fractional Units shall be sold unless
agreed to by the Company and Spelman & Co., Inc., Paradise Valley Securities,
Inc., and Sentra Securities Corporation, the Company's placement agents in this
offering (collectively, the "Placement Agents"). The Common Shares underlying
the Units shall conform to the description thereof in the Memorandum (as
defined below).

2.       PURCHASE AND SALE

         2.1 Units. Subject to all of the terms and conditions of this
Agreement, the Company will issue and sell to you (sometimes referred to as
"Holder") the number of Units shown on the signature page hereof and you will
purchase the same from the Company; provided that Units in the aggregate amount
of at least $ 1,150,000 have been subscribed and paid for by you and the Other
Purchasers and all other terms and conditions set forth in this Purchase
Agreement are satisfied. You acknowledge that Units subscribed and paid for by
officers, directors or employees of the Company, or by holders of the Company's
outstanding securities, or by officers or employees of any Placement Agent for
their own account, or by an affiliate of any of the foregoing, shall be counted
in determining whether all or any part of Units in the aggregate amount of at
least $1,150,000 have been subscribed and paid for.

         2.2 Funds Escrow Account. The funds tendered by you pursuant to this
Agreement will be deposited in a special escrow account (the "Fund") at the
First Arizona Savings and Loan Association ("Funds Escrow Agent"), whose
address is 4141 North Scottsdale Road, Suite 140, Scottsdale, Arizona 85251,
and will be returned to you without interest or deduction for escrow fees and
expenses, if: (a) your subscription for the purchase of Units pursuant to this
Agreement has not been accepted by the Company or (b) if Purchase Agreements
for at least 200 Units and funds in the amount of at least $1,150,000 are not
deposited in the Fund before the close of business on May 31, 1998, which date
may be extended one or more times by agreement of the Company and the Placement
Agents, without notice to you and the Other Purchasers, to a date not later
than June 30, 1998 (the "Termination Date"). It is understood and agreed that
if this Agreement is accepted by the Company, and the funds in payment of a
minimum of 200 Units are received and accepted by the Company before the close
of business on the Termination Date, then at the Closing (as defined below)
with respect to the Units subscribed for by you, the funds tendered herewith
(less any fees paid to the Placement Agents), shall be delivered to the Company
by the Funds Escrow Agent in payment for the Units subscribed for by you, or
such lesser amount as may be allocated to you by the Company. If you are
allocated less than the full amount of the Units subscribed for by you and the
full amount of the Units subscribed for has been timely paid in full by you,
the Company shall instruct the Funds Escrow Agent to remit the overpayment of
the amount paid, without

                                       1
<PAGE>   2


interest or deduction, to you within fifteen days after such partial acceptance
of this Purchase Agreement. The Units are being offered by the Company subject
to the right of the Company and Placement Agents to reject, at their
discretion, any subscription, in whole or in part, for any reason, and to
accept subscriptions notwithstanding the order in which they are received.

         2.3 Closing. The purchase by and sale and delivery to you and Other
Purchasers of the Units (the "Closing") shall take place at the offices of the
Placement Agents or of the Funds Escrow Agent at such date and time, or at such
other place, upon which the Company and the Placement Agents may agree (such
date being hereinafter called the "Closing Date"). At the Closing, the Company
shall deliver to a representative of the Placement Agents on your behalf,
instruments evidencing the Common Shares comprising the Units being purchased
by you and other items required to be delivered to it pursuant to this Purchase
Agreement. If at any time prior to the Termination Date, subscriptions for at
least 200 Units have been received and accepted by the Company, and the full
purchase price for such Units have been deposited into the Fund, the Company
may have an initial closing ("Initial Closing") with respect to such accepted
subscriptions and continue to offer the remaining Units until the Termination
Date or all 900 Units (1,210 if the Company's over-allotment option is
exercised in full) have been sold, whichever occurs earlier; provided, however,
that the final Closing shall take place not later than ten days after the
Termination Date.

3.       REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE COMPANY

         As an inducement to you to enter into this Agreement, the Company
represents, warrants and agrees that:

         3.1 Disclosure Documents. The Company has prepared the Company's
Confidential Private Offering Memorandum ("Memorandum") dated April 8, 1998,
together with all exhibits annexed thereto (such Memorandum and exhibits
annexed thereto are called collectively herein the "Disclosure Documents",
which term shall include any additions or supplements thereto).

         3.2 Description of Securities. The Common Shares when issued and
delivered will conform to the description thereof under the captions
"Description of Securities" and "Description of the Offering" in the
Memorandum.

         3.3 Authority for Agreement. This Agreement has been duly authorized
by all necessary action of the Company and, when executed and delivered by the
Company, will be a legal, valid and binding obligation of the Company,
enforceable in accordance with its terms, except to the extent that the
enforceability hereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other laws affecting creditors' rights generally or by general
principles of equity, and except that the indemnification provisions of the
Agreement may be held to be violative of public policy under either federal or
state laws in the context of the offer or sale of securities.

         3.4 Validity of Common Stock. The Common Shares, when issued and paid
for at the Closing, will constitute duly authorized, legally issued shares of
Common Stock.

         3.5 No Conflicting Rights. The holders of the outstanding capital
stock of the Company are not entitled to pre-emptive or other rights to
subscribe for the Units. Other than as set forth in the Memorandum, the
offering of the Units as contemplated by the Memorandum does not give rise to
any rights relating to the registration of any outstanding capital stock.

         3.6 Disclosure. The Company has provided you with all of the material
information which you have reasonably requested in deciding whether to invest
in the Units.

                                       2

4.       REPRESENTATIONS, WARRANTIES AND AGREEMENTS BY YOU

         You hereby represent, warrant and agree that:

         4.1 Authority. You have full power and authority to enter into this
Agreement and it constitutes your legal, valid and binding obligation,
enforceable in accordance with its terms.

         4.2 Purchase For Own Account. You are acquiring the Units for your own
account, for investment purposes and not for resale or with a view to any
distribution, or in connection with any distribution thereof you are able to
(i) bear the economic risk of your investment in the Units, (ii) hold the Units
for an indefinite period of time, and (iii) afford a complete loss of your
investment.

         4.3 Investment Experience. You have the requisite knowledge and
experience in financial and business matters, including investments of this
type, to be capable of evaluating the merits and risks of an investment in the
Units and of making an informed investment decision with respect thereto.

         4.4 Receipt Of Information. You have received, read carefully,
considered and fully understood the Disclosure Documents and you have received
from the Company all of the information concerning the Company which you
consider to be material in making your investment decision, which information
has been requested by you if not already furnished by the Company. You have had
full access to the books and records of the Company and to its officers,
directors and accountants for the purpose of obtaining and verifying such
information and you have had an opportunity to ask questions and receive
answers from the officers of the Company regarding the terms and conditions of
this transaction and the Company's business and financial condition.

         Except as expressly set forth in the Disclosure Documents, no
representations or warranties, oral or otherwise, have been made to you,
including without limitation, any representations concerning the future
prospects of the Company, by the Company, any Placement Agent or any agent
employee or affiliate of the Company or of any Placement Agent or any other
person whether or not associated with this action, and in entering into this
action you are not relying upon any information other than that contained in
the Disclosure Documents, and the results of your own independent
investigation. You have obtained sufficient information to evaluate the merits
and risks of your investment and to make an informed investment decision.

         4.5 Restricted Securities. You understand and acknowledge that the
Common Shares you are purchasing hereunder are "restricted securities" under
United States federal and state securities laws insofar as they have not been
registered under the Securities Exchange Act of 1933, as amended (the "1933
Act"), or the securities laws of any other jurisdiction, that they may not be
resold or transferred without compliance with the registration or qualification
provisions of the 1933 Act or applicable federal and state securities laws of
any state or other jurisdiction or an opinion of counsel acceptable to the
Company that an exemption from such registration and qualification requirements
is available.

         4.6 Limitations on Disposition. Without in any way limiting the
representations set forth above, you further agree not to make any disposition
of all or any portion of the Common 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) You 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) you have furnished
the Company with an opinion of counsel, reasonably satisfactory to the Company,
that such disposition will not require registration of such securities under
the 1933 Act and applicable securities laws of any state or other jurisdiction.

                                       3
<PAGE>   4

         4.7 Illiquid Investments. Your overall commitment to investments which
are not readily marketable is not disproportionate to your net worth and your
investment in the Units will not cause such overall commitment to become
excessive. You have adequate means of providing for your current needs and
personal contingencies.

         4.8 Accredited Investor. You are an "Accredited Investor" as such term
is defined in the Memorandum and Rule 501(a) promulgated under the 1933 Act.

         4.9 Company Reliance On Questionnaire. You understand, acknowledge and
agree that the Company, in entering into and performing under this Agreement,
is relying on the accuracy of the responses by you to the Purchaser
Questionnaire heretofore delivered by you to the Company, which responses you
warrant to be true, complete and correct.

<PAGE>   5

                  (c) The term "Public Company" means a corporation which has a
         class of equity securities registered pursuant to Section 12 of the
         1934 Act, or which is required to file periodic reports pursuant to

                  (d) The term "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 effectiveness of such
         registration statement or document.

                  (e) The term "Registrable Securities" means (i) the Common
         Shares purchased by a Purchaser or Other Purchaser under this or
         similar Purchase Agreement and (ii) any 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
         the shares referenced in (i) above, excluding in all cases, however,
         any Registrable Securities (1) sold by a person in a transaction in
         which his rights under this Section 7 are not assigned or (II)
         registered under the 1933 Act, the registration statement in
         connection therewith has been declared effective, and such shares have
         been disposed by such holder pursuant to such registration statement.

                  (f) The number of shares of "Registrable Securities then
         outstanding" shall be determined by the number of shares of Common
         Stock outstanding which are, and the number of shares of Common Stock
         issuable pursuant to then exercisable or convertible securities which
         are, Registrable Securities.

         Agreement.

         7.2 Piggyback Registration. If (but without any obligation to do so)
the Company proposes to register (including for this purpose a registration
effected by the Company for stockholders other than the Holders) any of its
Common Stock or other securities under the 1933 Act in connection with the
public offering of such securities solely for cash (other than an initial
public offering, registration relating solely to the sale of securities to
participants in a Company stock option, stock purchase or similar employee
benefit plan, a registration on any form which does not include substantially
the same information as would be required to be included in a registration
statement covering the sale of the Registrable Securities (including Form S-4
or any form substitution thereof) or a registration in which the only Common
Stock being registered is Common Stock issuable upon conversion of debt
securities which are also being registered or a SEC Rule 145 transaction), the
Company shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within twenty
calendar days after mailing of such notice by the Company, the Company shall,
subject to the provisions of Section 7.6, cause to be registered under the 1933
Act and any applicable state securities laws all of the Registrable Securities
that each such Holder has requested to be registered.

         7.3 Obligations of the Company. Whenever under this Section 7 the
Company effects the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                  (a) Prepare and file with the SEC on any appropriate form a
         registration statement with respect to such Registrable Securities and
         use its best efforts to cause such registration statement to become
         effective;

                  (b) Unless such registration is a firm commitment
         underwriting, prepare and file with the SEC such amendments (including
         post-effective amendments) and supplements to such registration
         statement and the prospectus used in connection therewith as may be
         necessary to keep such registration statement effective and to comply
         with the provisions of the 1933 Act with respect to the disposition of
         all Registrable Securities and other securities covered by such
         registration statement for a period of 270 days.

                                       5
<PAGE>   6

                  (c) Furnish to the Holders 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 them.

                  (d) Use its best efforts to register or qualify all
         Registrable Securities and other securities covered by such
         registration statement under such other securities or "blue sky" laws
         of such jurisdictions as the underwriter or such sellers (not to
         exceed ten) shall reasonably request and do any and all other acts and
         things as may be reasonably necessary to consummate the disposition in
         such jurisdictions of the Registrable Securities covered by such
         registration statement, except that the Company shall not for any such
         purpose be required to qualify generally to do business as a foreign
         corporation in any jurisdiction wherein it is not so qualified, or to
         subject itself to taxation in respect of doing business in any such
         jurisdiction, or to consent to general service of process in any such
         jurisdiction.

                  (e) Immediately notify each seller of Registrable Securities
         covered by such registration statement, 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 any material
         fact required to be stated therein or necessary to make the statements
         therein not misleading in the light of the circumstances then existing
         or if its is necessary, in the opinion of counsel to the Company, to
         amend or supplement such prospectus to comply with law, and at the
         request of any such seller prepare and sh to such seller a reasonable
         number of copies of a supplement to or any amendment of such
         prospectus as may be necessary so that, as thereafter delivered to the
         purchasers of such Registrable Securities, such prospectus shall not
         include an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading in the light of the circumstances
         then existing and shall otherwise comply in all material respects with
         law and so that such prospectus, as amended or supplemented, will
         comply with law.

                  (f) Otherwise use its best efforts to comply with all
         applicable rules and regulations of the SEC, any make available to its
         securityholders, as soon as reasonably practicable, an earnings
         statement covering the period of at least twelve (12) months,
         beginning with the first month of the first fiscal quarter after the
         effective date of such registration statement, which earnings
         statement shall satisfy the provisions of Section I 1 (a) of the 1933
         Act.

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

                  (h) 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 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 the light of the circumstances then
         existing.

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

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

                                       6

         7.4 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 7 with
respect to the Registrable Securities of any selling Holder that such Holder
shall sh to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such
securities as shall be required to effect the registration of such Holder's
Registrable Securities.

         7.5 Expenses of Registration. All expenses incurred in connection with
registrations, filings or qualifications pursuant to this Section 7, including,
without limitation, all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for the Company, but
excluding fees and disbursements of counsel to the selling Holders,
underwriter's commissions and fees and any fees of others employed by a selling
Holder, shall be borne by the Company.

         7.6 Underwriting Requirements. In connection with any offering
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 7.2 to include any of the Holders'
securities in such underwriting unless they accept the terms of the
underwriting as agreed upon between the Company and the underwriters selected
by it (or by other persons entitled to select the underwriters), and then only
in such quantity as the underwriters determine in their sole discretion will
not materially jeopardize or in any way reduce the success of the offering by
the Company. If the total amount of securities, including Registrable
Securities, requested by security holders to be included in such offering
exceeds the amount of securities sold other dm by the Company that the
underwriters determine in their sole discretion is compatible with the success
of the offering, then the Company shall be required to include in the offering
only that number of such securities, including Registrable Securities, which
the underwriters determine in their sole discretion will not jeopardize the
success of the offering (the securities so included to be apportioned pro rata
among the selling security holders (including Holders) according to the total
amount of securities entitled to be included therein owned by each selling
shareholder (including Holders) or in such other proportions as shall mutually
be agreed to by such selling shareholders (including Holders)).

         7.7 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 7.

         7.8 Indemnification. In the event any Registrable Securities are
included in a registration statement under this Section 7:

                  (a) To the extent permitted by law, the Company will
         indemnify and hold harmless each Holder, any underwriter (as defined
         in the 1933 Act) for such Holder and each person, if any, who controls
         such Holder or underwriter within the meaning of the 1933 Act or the
         1934 Ac 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, subject to subsection 7.8 (c) below,
         the Company will pay to each such Holder, underwriter or controlling
         person, as incur-red, any legal or other expenses reasonably incurred
         by them in connection with investigating or defending any such loss,
         claim, damage, liability, or action; provided, however, that the
         indemnity agreement contained in this subsection 7.8(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 reasonably
         withheld), nor shall the

                                       7
<PAGE>   8

         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 any such Holder, underwriter or controlling
         person.

                  (b) 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 has signed the registration statement, each
         person, if any, who controls the Company within the meaning of the
         1933 Act, any underwriter, any other Holder selling securities in such
         registration statement and any controlling person of any such
         underwriter or other Holder, and any agent of the Company, 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 such Holder
         expressly for use in connection with such registration; and each such
         Holder will pay, as incurred, any legal or other expenses reasonably
         incurred by any person intended to be indemnified pursuant to this
         subsection 7.8(b), in connection with investigating or defending any
         such loss, claim, damage, liability, or action; provided, however,
         that the indemnity agreement contained in this subsection 7.8(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 reasonably withheld;
         provided, that, in no event shall any indemnity under this subsection
         7.8(b) exceed the gross proceeds from the offering received by such
         Holder.

                  (c) Promptly after receipt by an indemnified party under this
         Section 7.8 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 7.8, 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 receiving similar
         notice, to assume the defense thereof with counsel reasonably
         satisfactory to the parties; provided, however, that an indemnified
         party (together with all other indemnified party which may be
         represented without conflict by one counsel) shall have the right to
         retain one separate counsel, with the fees and expenses to be paid by
         the indemnifying party, if representation of such indemnified party by
         the counsel retained by the indemnifying party would be inappropriate
         due to actual or potential differing interests between such
         indemnified party and any other party represented by such counsel in
         such proceeding; otherwise, the indemnified party shall be responsible
         for the fees and expenses of its counsel. 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 7.8.

                  (d) Except as provided in the last sentence of subsection
         7.8(c) above, if the indemnification provided for in this Section 7.8
         is held by a court of competent jurisdiction to be unavailable to an
         indemnified party with respect to any loss, liability, claim, damage,
         or expense referred to therein, then the indemnifying party, in lieu
         of indemnifying such indemnified party hereunder, shall contribute to
         the amount paid or payable by such indemnified party as a result of
         such loss, liability, claim, damage, or expense in such proportion as
         is appropriate to reflect the relative fault of the indemnifying party
         on the one hand and of the indemnified party on the other in
         connection with the statements or omissions that resulted in such
         loss, liability, claim, damage, or expense as well as any other
         relevant equitable considerations. The relative fault of the
         indemnifying party and of the indemnified party shall be determined by
         reference to, among other things, whether the untrue or alleged untrue
         statement of a material fact or the omission to state a material fact
         relates to information supplied by the indemnifying party or by the
         indemnified party.

                                       8
<PAGE>   9

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

                  (f) The obligations of the Company and Holders under this
         Section 7.8 shall survive the completion of any offering of
         Registrable Securities pursuant to a registration statement under this
         Section 7.

         7.9 Assignment of Piggyback Rights. Subject to the provisions of
Section 7.10, the piggyback registration rights of the Holders under Section
7.2 may be assigned (but only with all related obligations) by a Holder to a
permitted transferee or assignee of such securities who, after such assignment
or transfer, holds at least 10,000 shares of Registrable Securities (subject to
appropriate adjustment for stock splits, stock dividends, combinations and
other recapitalizations), provided: (a) the Company is, within a reasonable
time after such transfer, furnished with written notice of the name and address
of such transferee or assignee and the securities with respect to which such
piggyback registration rights are being assigned; (b) such transferee or
assignee agrees in writing to be bound by and subject to the terms and
conditions of this Agreement, including without limitation the provisions of
Section 7.10 below; and (c) such assignment shall be effective only if
immediately following such transfer the further disposition of such securities
by the transferee or assignee is restricted under the 1933 Act. For the
purposes of determining the number of shares of Registrable Securities held by
a transferee or assignee, the holdings of transferees and assignees of a
partnership who are partners or retired partners of such partnership (including
spouses and ancestors, lineal descendants and siblings of such partners or
spouses who acquire Registrable Securities by gift, will or intestate
succession) shall be aggregated together and with the partnership; provided
that all assignees and transferees who would not qualify individually for
assignment of registration rights shall have a single attorney-in-fact for the
purpose of exercising any rights, receiving notices or taking any action under
this Section 7.

         7.10 "Lock-up" Agreement. Each Holder hereby agrees that he or she
shall not, for the period commencing on the date of such Holder's Unit Purchase
Agreement and ending 120 days after the earlier of: (i) the effective date of a
registration statement under the 1933 Act covering all of the Registrable
Securities or (ii) the effective date of a registration statement filed by the
Company pursuant to Section 7.2 hereof, without the prior written approval of
the Placement Agents and the managing underwriter in such registration directly
or indirectly, sell, offer to sell, contract to sell (including without
limitation, any short sale), grant any option to purchase or otherwise transfer
or dispose of (other than to donees who agree to be similarly bound) any shares
of Common Stock legally or beneficially owned by such Holder.

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

         7.11 Termination of Registration Rights. No Holder shall be entitled
to exercise any right provided for in this Section 7 after three (3) years
following the date after the Company becomes a Public Company.

         7.12 Amendments and Waivers. Any term or provision of the registration
rights stated in this Section 7 may be amended and the observance of any term
of such rights may be waived (either generally or in a particular instance and
either retroactively or prospectively), only with the written consent of the
Company and the holders of at least fifty-one percent (51%) of the Registrable
Securities then outstanding. Any amendment or waiver effected in accordance
with this Section 7.12 shall be binding upon each holder of any Registrable
Securities then outstanding, each future holder of all such Registrable
Securities, and the Company.

8.       FURTHER AGREEMENTS

         You agree that:

                                      9

follows:

         The Company, by due action of its Board of Directors, has authorized
the offer and sale to you under this Unit Purchase Agreement ("Agreement" or
"Purchase Agreement") and to other purchasers under similar Purchase Agreements
("Other Purchasers") of up to 875 Units (963 if the Company's over-allotment
option is exercised in full), each consisting of 2,000 shares of common stock,
par value $ .01 per share ("Common Stock"), of the Company ("Common Shares") and

of at least $ 1,000,000 have been subscribed and paid for by you and the Other
Purchasers and all other terms and conditions set forth in this Purchase
Agreement are satisfied. You acknowledge that Units subscribed and paid for
(whether paid for by cash, cancellation of indebtedness or conversion of
outstanding shares of the Company's Series B Preferred Stock) by officers,
directors or employees of the Company, or by holders of the Company's
outstanding securities, or by officers or employees of any Placement Agent for

          2.2 Funds Escrow Account. The funds tendered by you pursuant to this
Agreement will be deposited in a special escrow account (the "Fund") at the
First Arizona Savings and Loan Association ("Funds Escrow Agent"), whose address
is 4141 North Scottsdale Road, Suite 140, Scottsdale, Arizona 85251, and will be
returned to you without interest or deduction for escrow fees and expenses, if:
(a) your subscription for the purchase of Units pursuant to this Agreement has
not been accepted by the Company or (b) if Purchase Agreements for at least 125
Units and funds in the amount of at least $1,000,000 are not deposited in the
Fund before the close of business on November 14, 1997, which date may be
extended one or more times by agreement of the Company and the Placement Agents,
without notice to you and the Other Purchasers, to a date not later than
December 31, 1997 (the "Termination Date"). It is understood and agreed that if
this Agreement is accepted by the Company, and the funds in payment of a minimum
of 125 Units are received and accepted by the Company before the close of
business on the Termination Date, then at the Closing (as defined below) with
respect to the Units subscribed for by you, the funds tendered herewith (less
any fees paid to the Placement Agents), shall be delivered to the Company by the
Funds Escrow Agent in payment for the Units subscribed for by you, or such
lesser amount as may be allocated to you by the Company. If you are allocated
less than the full amount of the Units subscribed for by you and the full amount
of the Units subscribed for has been timely paid in full by you, the Company
shall instruct the Funds Escrow Agent to remit the overpayment of the amount
paid, without interest or deduction, to you within fifteen days after such
partial acceptance of this Purchase Agreement. The Units are being offered by
the Company subject to the right of the Company and Placement Agents to reject,
at their discretion, any subscription, in whole or in part, for any reason, and
to accept subscriptions notwithstanding the order in which they are received.

         2.3 Closing . The purchase by and sale and delivery to you and Other
Purchasers of the Units (the "Closing") shall take place at the offices of the
Placement Agents or of the Funds Escrow Agent at such date and time, or at such
other place, upon which the Company and the Placement Agents may agree (such
date being hereinafter called the "Closing Date"). At the Closing, the Company
shall deliver to a representative of the Placement Agents on your behalf,
instruments evidencing the Common Shares and Warrant comprising the Units being
purchased by you and other items required to be delivered to it pursuant to this
Purchase Agreement. If at any time prior to the Termination Date, subscriptions
for at least 125 Units have been received and accepted by the Company, and the
full purchase price for such Units have been deposited into the Fund, the
Company may have an initial closing ("Initial Closing") with respect to such
accepted subscriptions and continue to offer the remaining Units until the
Termination Date or all 875 Units (963 if the Company's over-allotment option is
exercised in full) have been sold, whichever occurs earlier; provided, however,
that the final Closing shall take place not later than ten days after the
Termination Date.

          purpose be required to qualify generally to do business as a foreign
          corporation in any jurisdiction wherein it is not so qualified, or to
          subject itself to taxation in respect of doing business in any such

          and perform its obligations under an underwriting agreement, in usual
          and customary form, with the managing underwriter of such offering.

          and perform its obligations under such an agreement.

          registration statement 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 the light of the circumstances then
          existing.

<PAGE>   9

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

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

          7.4  Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 7 with
respect to the Registrable Securities of any selling Holder that such Holder
shall sh to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

          7.5  Expenses of Registration. All expenses incurred in connection
with registrations, filings or qualifications pursuant to this Section 7,

Holder, shall be borne by the Company.

         7.6  Underwriting Requirements. In connection with any offering
involving an underwriting of shares of the Company's capital stock, the Company
shall not be required under Section 7.2 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not
materially jeopardize or in any way reduce the success of the offering by the
Company. If the total amount of securities, including Registrable Securities,
requested by security holders to be included in such offering exceeds the amount
of securities sold other than by the Company that the underwriters determine in
their sole discretion is compatible with the success of the offering, then the
Company shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters determine
in their sole discretion will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling security
holders (including Holders) according to the total amount of securities entitled
to be included therein owned by each selling shareholder (including Holders) or
in such other proportions as shall mutually be agreed to by such selling
shareholders (including Holders)).

         7.7  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 7.

              (a) To the extent permitted by law, the Company will indemnify and
          hold harmless each Holder, any underwriter (as defined in the 1933
          Act) for such Holder and each person, if any, who controls such 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, subject to subsection 7.8 (c) below, the Company
          will pay to each such Holder, underwriter or controlling person, as
          incurred, any legal or other expenses reasonably incurred by them in
          connection with investigating or defending any such loss, claim,
          damage, liability, or action; provided, however, that the indemnity
          agreement contained in this subsection 7.8(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 reasonably 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 any such Holder, underwriter or controlling
          person.

              (b) 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 has signed the registration statement, each
          person, if any, who controls the Company within the meaning of the
          1933 Act, any underwriter, any other Holder selling securities in such
          registration statement and any controlling person of any such
          underwriter or other Holder, and any agent of the Company, 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 such Holder
          expressly for use in connection with such registration; and each such
          Holder will pay, as incurred, any legal or other expenses reasonably
          incurred by any person intended to be indemnified pursuant to this
          subsection 7.8(b), in connection with investigating or defending any
          such loss, claim, damage, liability, or action; provided,


                                       10
<PAGE>   11

          however, that the indemnity agreement contained in this subsection
          7.8(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
          reasonably withheld; provided, that, in no event shall any indemnity
          under this subsection 7.8(b) exceed the gross proceeds from the
          offering received by such Holder.

              (c) Promptly after receipt by an indemnified party under this
          Section 7.8 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 7.8, 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 receiving similar
          notice, to assume the defense thereof with counsel reasonably
          satisfactory to the parties; provided, however, that an indemnified
          party (together with all other indemnified party which may be
          represented without conflict by one counsel) shall have the right to
          retain one separate counsel, with the fees and expenses to be paid by
          the indemnifying party, if representation of such indemnified party by
          the counsel retained by the indemnifying party would be inappropriate
          due to actual or potential differing interests between such
          indemnified party and any other party represented by such counsel in
          such proceeding; otherwise, the indemnified party shall be responsible
          for the fees and expenses of its counsel. 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 7.8.

              (d) Except as provided in the last sentence of subsection 7.8(c)
          above, if the indemnification provided for in this Section 7.8 is held
          by a court of competent jurisdiction to be unavailable to an
          indemnified party with respect to any loss, liability, claim, damage,
          or expense referred to therein, then the indemnifying party, in lieu
          of indemnifying such indemnified party hereunder, shall contribute to
          the amount paid or payable by such indemnified party as a result of
          such loss, liability, claim, damage, or expense in such proportion as
          is appropriate to reflect the relative fault of the indemnifying party
          on the one hand and of the indemnified party on the other in
          connection with the statements or omissions that resulted in such
          loss, liability, claim, damage, or expense as well as any other
          relevant equitable considerations. The relative fault of the
          indemnifying party and of the indemnified party shall be determined by
          reference to, among other things, whether the untrue or alleged untrue
          statement of a material fact or the omission to state a material fact
          relates to information supplied by the indemnifying party or by the
          indemnified party.

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

                                       11
<PAGE>   12

              (f) The obligations of the Company and Holders under this Section
          7.8 shall survive the completion of any offering of Registrable
          Securities pursuant to a registration statement under this Section 7.

         7.9  Assignment of Piggyback Rights. Subject to the provisions of
Section 7.10, the piggyback registration rights of the Holders under Section 7.2
may be assigned (but only with all related obligations) by a Holder to a
permitted transferee or assignee of such securities who, after such assignment
or transfer, holds at least 10,000 shares of Registrable Securities (subject to
appropriate adjustment for stock splits, stock dividends, combinations and other
recapitalizations), provided: (a) the Company is, within a reasonable time after
such transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such piggyback
registration rights are being assigned; (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement, including without limitation the provisions of Section 7.10 below;
and (c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the 1933 Act. For the purposes of determining the
number of shares of Registrable Securities held by a transferee or assignee, the
holdings of transferees and assignees of a partnership who are partners or
retired partners of such partnership (including spouses and ancestors, lineal
descendants and siblings of such partners or spouses who acquire Registrable
Securities by gift, will or intestate succession) shall be aggregated together
and with the partnership; provided that all assignees and transferees who would
not qualify individually for assignment of registration rights shall have a
single attorney-in-fact for the purpose of exercising any rights, receiving
notices or taking any action under this Section 7.

         7.10 "Lock-up" Agreement. Each Holder hereby agrees that he or she
shall not, for the period commencing on the date of such Holder's Unit Purchase
Agreement and ending 120 days after the earlier of: (i) the effective date of a
registration statement under the 1933 Act covering all of the Registrable
Securities or (ii) the effective date of a registration statement filed by the
Company pursuant to Section 7.2 hereof, without the prior written approval of
the Placement Agents and the managing underwriter in such registration directly
or indirectly, sell, offer to sell, contract to sell (including without
limitation, any short sale), grant any option to purchase or otherwise transfer
or dispose of (other than to donees who agree to be similarly bound) any shares
of Common Stock (including shares of Common Stock issuable upon the exercise of
the Warrants) legally or beneficially owned by such Holder.

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

         7.11 Termination of Registration Rights. No Holder shall be entitled to
exercise any right provided for in this Section 7 after three (3) years
following the date after the Company becomes a Public Company.

                                       12
<PAGE>   13

         7.12 Extension of Warrant Exercise Period. In the event the holders of
Warrants are delayed in selling the shares of Common Stock underlying the
Warrants at the time such holders desire pursuant to the terms of Section 7.2 or
7.11, the parties hereto agree that the exercise period for the Warrants shall
be extended by the amount of such delay.

         7.13 Amendments and Waivers. Any term or provision of the registration
rights stated in this Section 7 may be amended and the observance of any term of
such rights may be waived (either generally or in a particular instance and
either retroactively or prospectively), only with the written consent of the
Company and the holders of at least fifty-one percent (51%) of the Registrable
Securities then outstanding. Any amendment or waiver effected in accordance with
this Section 7.13 shall be binding upon each holder of any Registrable
Securities then outstanding, each future holder of all such Registrable
Securities, and the Company.

AMENDED (THE "ACT"), OR UNDER THE SECURITIES LAWS OF ANY STATE OR OTHER

                             SHARES OF COMMON STOCK

         THIS CERTIFIES THAT, for value received, or registered successors or
assigns (hereinafter, the "Holder"), is entitled to purchase, subject to the
conditions set forth below, at any time or from time to time during the Exercise
Period (as defined in subsection 1. 1 below), __________ (___ ) fully paid and
non-assessable shares (the "Shares") of the common stock, par value $0.01 per
share (the "Common Stock"), of Mobility Electronics, Inc., a Delaware
corporation (the "Company"), at a purchase price of $0.01 per share, subject to
adjustment as provided in Section 4 below (the "Warrant Price").

1.       EXERCISE OF WARRANT

         The terms and conditions upon which this Warrant may be exercised, and
the Common Stock covered hereby may be purchased, are as follows:

         1.1 Method Of Exercise. The Holder of this Warrant may, at any time, or
from time to time, on or after ____________ but on or prior to ________, 2002,
exercise in whole or in part the purchase rights evidenced by this Warrant. Such
exercise shall be effected by: (a) the surrender of the Warrant, together with a
duly executed copy of the form of subscription attached hereto, to the Chief
Executive Officer of the Company at the Company's New Mexico office; and (ii)
the payment to the Company, by certified check or bank draft payable to its
order, of an amount equal to the aggregate warrant Price for the number of
Shares for which the purchase rights hereunder are being exercised.

         1.2 Satisfaction with Requirements of Securities Act of 1933.
Notwithstanding anything herein to the contrary, each and every exercise of this
Warrant is contingent upon the Company's satisfaction that the issuance of
Common Stock upon the exercise is exempt from the requirements of the Securities
Act of 1933, as amended (the "Act") and all applicable state securities laws.
The




<PAGE>   2


Holder of this Warrant agrees to execute any and all documents determined
necessary by the Company's counsel to effect the exercise of this Warrant.

         1.3 Issuance Of Shares and New Warrant. In the event the purchase
rights evidenced by this Warrant are exercised in whole or in part, one or more
certificates for the purchased Shares shall be issued as soon as practicable
thereafter to the person exercising such rights. Such Holder shall also be
issued at such time a new Warrant representing the number of Shares (if any) for
which the purchase rights under this Warrant remain unexercised and continuing
in force and effect.

2.       TRANSFERS

         2.1 Transfers. Subject to Section 7 below, this Warrant and all rights
hereunder are transferable in whole or in part by the Holder. The transfer shall
be recorded on the books of the Company upon the surrender of this Warrant,
properly endorsed, to the Chief Executive Officer of the Company at the
Company's New Mexico office and the payment to the Company of all transfer taxes
and other governmental charges imposed on such transfer. In the event of a
partial transfer, the Company shall issue to the several Holders one or more
appropriate new Warrants.

         2.2 Registered Holder. Each Holder agrees that until such time as any
transfer pursuant to subsection 2.1 is recorded on the books of the Company, the
Company may treat the registered Holder of this Warrant as the absolute owner;
provided that nothing herein affects any requirement that transfer of any
Warrant or share of Common Stock issued or issuable upon the exercise thereof by
subject to securities law compliance.

         2.3 Form Of New Warrants. All Warrants issued in connection with
transfers of this Warrant shall bear the same date as this Warrant and shall be
substantially identical in form and provision to this Warrant, with the possible
exception of the number of Shares purchasable thereunder.

3.       FRACTIONAL SHARES

         Notwithstanding that the number of Shares purchasable upon the exercise
of this Warrant may have been adjusted pursuant to the terms hereof, the Company
shall nonetheless not be required to issue fractions of Shares upon exercise of
this Warrant or to distribute certificates that evidence fractional shares nor
shall the Company be required to make any cash payments in lieu thereof upon
exercise of this Warrant. Holder hereby waives any night to receive fractional
Shares. If a fractional Share shall result from adjustments in the number of
Shares purchasable hereunder, the number of Shares purchasable hereunder shall,
on an aggregate basis taking into account all adjustments hereunder from the
date of issuance of this Warrant, be rounded up to the next whole number.

4.       ANTIDILUTION PROVISIONS

         The provisions of this Section 4 shall apply in the event that any of
the events described in this Section 4 shall occur with respect to the Common
Stock at any time on or after the original issuance date of this Warrant:

         4.1 Stock Splits And Combinations. If the Company shall at any time
subdivide or combine its outstanding shares of Common Stock, this Warrant shall,
after that subdivision or combination, evidence the night 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 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 shall
become effective at the time that such subdivision or combination becomes
effective.

         4.2 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 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 for the same aggregate consideration,
in lieu of the Common Stock which the Holder would have become entitled to
purchase but for such change, the number of shares of such other 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.

         4.3 Reorganizations, Mergers, Consolidations Or Sale Of Assets. If at
any time there shall be a capital reorganization of the Common Stock (other than
a combination, reclassification, exchange, or subdivision of shares provided for
elsewhere above) then, as a part of such 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 Common Stock or other securities or property of the Company to which a
holder of the 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. In any such case, appropriate
adjustment (as determined in good faith by the Company's Board of Directors)
shall be made in the application of the provisions of this Warrant with respect
to the rights and interests of the Holder of this Warrant after the
reorganization to the end that the provisions of this Warrant (including
adjustment of the Warrant Price then in effect and number of Shares purchasable
upon exercise of this Warrant) shall be applicable after that event, as near as
reasonably may be, in relation to any shares or other property deliverable after
that event upon exercise of this Warrant.

         4.4 Common Stock Dividends, Distributions. In the event the Company
should at any time prior to the expiration of this Warrant fix a record date for
the determination of the holders of Common Stock entitled to receive a dividend
or other distribution payable in additional shares of Common Stock or other
securities or rights convertible into or entitling the holder thereof to
receive, directly or indirectly, additional shares of Common Stock (hereinafter
referred to as the "Common Stock Equivalents") without payment of any
consideration by such holder for the additional shares of Common Stock or Common
Stock Equivalents (including the additional shares of Common Stock issuable upon
conversion or exercise thereof), then, as of such record date (or the date of
such distribution, split or subdivision if no record date is fixed), the Warrant
Price shall be appropriately decreased and the number of shares of Common Stock
issuable upon exercise of the Warrant shall be appropriately increased in
proportion to such increase of outstanding shares.

         4.5 Adjustments of Other Distributions. In the event the Company shall
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by the Company or other persons, assets (excluding cash
dividends) or options or rights not referred to in subsection 4.4, then, in each
such case for the purpose of this subsection 4.5, upon exercise of this Warrant
the Holder hereof shall be entitled to a proportionate share of any such
distribution as though such Holder was the holder of the number of shares of
Common Stock into which this Warrant may be exercised as of the record date
fixed for the determination of the holders of Common Stock entitled to receive
such distribution.

         4.6 Certificate as to Adjustments. In the case of each adjustment or
readjustment of the arrant Price pursuant to this Section 4, the Company will
promptly compute such adjustment or readjustment in accordance with the terms
hereof and cause a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based,
to be delivered to the Holder of this Warrant. The Company will, upon the
written request at any time of the Holder of this Warrant, furnish or cause to
be furnished to such older a certificate setting forth: (a) such adjustments and
readjustments; (b) the Warrant Price at he time in effect; and (c) the number of
shares of Common Stock issuable upon exercise of the arrant and the amount, if
any, of other property at the time receivable upon the exercise of the Warrant.

         4.7 Reservation of Stock Issuable Upon Exercise. The Company shall at
all times reserve and keep available out of its authorized but unissued shares

experience in financial and business matters, including investments of this
type, to be capable of evaluating the merits and risks of an investment in the
Securities and of making an informed investment decision with respect thereto.

         4.4 Receipt Of Information. You have received from the Company all of
the information concerning the Company which you consider to be material in
making your investment decision, which information has been requested by you if
not already furnished by the Company. You have had full access to the books and

laws of any state or other jurisdiction.

                                   Appendix I
                               Registration Rights

1.   Registration Rights.  The Company covenants and agrees with you as follows:

     1.1 Definitions.  For purposes of this Appendix I:

         (a) The term "Holder" means any person owning or having the right to
     acquire Registrable Securities or any assignee thereof in accordance with
     Section 1.11 hereof.

         (b) The term "1934 Act" shall mean the Securities Exchange Act of 1934,
     as amended.

         (c) The term "Public Company" means a corporation which has a class of
     equity securities registered pursuant to Section 12 of the 1934 Act, or
     which is required to file periodic reports pursuant to Section 15(d) of the
     1934 Act.

         (d) The term "register," "registered," and "registration" refer to a
     registration effected by preparing and filing a registration statement or
     similar document in compliance with the Act, and the declaration or
     ordering of effectiveness of such registration statement or document.

         (e) The term "Registrable Securities" means (i) the shares of Common
     Stock issued or issuable upon the exercise of the Warrants and (ii) any
     Common Stock 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 the
     shares referenced in (i) above, excluding in all cases, however, any
     Registrable Securities (I) sold by a person in a transaction in which his
     rights under this Section 1 are not assigned (II) registered under the Act,
     the registration statement in connection therewith has been declared
     effective, and such shares have been disposed by such holder pursuant to
     such registration statement; provided, however, that in either case of (i)
     or (ii) above, any such securities shall cease to be Registrable Securities
     if the registration rights granted hereunder are not transferred in
     accordance with the provisions of Section 1.11 below.

         (f) The number of shares of "Registrable Securities then outstanding"
     shall be determined by the number of shares of Common Stock issued or
     issuable upon exercise of the Warrants which are Registrable Securities.

         (g)  The term "SEC" shall mean the Securities and Exchange Commission.

         (h) All other capitalized terms used herein which are not defined
     herein shall have the meaning given elsewhere in this Agreement.

     1.2 Demand Registration.

         (a) From and after January 1, 2001, the Holders of at least 66 2/3% of
     the then outstanding Registrable Securities may notify the Company in
     writing that such Holders desire for the Company to cause all or a portion
     of such notifying Holders' Registrable Securities to be registered for sale
     to the public under the Act. Upon receipt of such written request, the
     company will promptly notify in writing all other Holders of Registrable
     Securities of such request, which Holders shall within twenty days
     following such notice from the Company, notify the Company in writing
     whether such persons desire to have Registrable Securities held by them
     included in such offering. The Company will, promptly following the
     expiration of such twenty day period, prepare and file subject to the
     provisions of this Section 1, and use its best efforts to prosecute to
     effectiveness, an appropriate filing with the SEC of a registration
     statement covering such Registrable Securities and the proposed sale or
     distribution thereof under the Act.

         (b) Notwithstanding anything in this Section 1.2 to the contrary, the
     Company shall not be obligated to prepare or file any registration
     statement pursuant to this Section 1.2 or to prepare or file any amendment
     or supplement


                                      A-1

<PAGE>   10


     thereto, at any time when the Company, in the good faith judgment of its
     Board of Directors, reasonably believes that the filing thereof at the time
     requested, or the offering of securities pursuant thereto, (i) would
     materially adversely affect a pending or proposed public offering of the
     Company's securities, or an acquisition, merger, recapitalization,
     consolidation, organization or similar transaction, negotiations,
     discussions or pending proposals with respect thereto or (ii) would
     materially adversely affect the business or prospects of the Company in
     view of the disclosures that may be required thereby of information about
     the business, assets, liabilities or operations of the Company not
     theretofore disclosed; provided, however, that the filing of a registration
     statement, or any supplement or amendment thereto, by the Company may be
     deferred pursuant to this Section 1.2 for no longer than 180 days (but only
     once in every twelve month period) after the delivery of such demand
     notice.

         (c) Notwithstanding anything in this Section 1.2 to the contrary: (i)
     the Company shall not be required to effect the registration of the
     Registrable Securities pursuant to this Section 1.2 more than one time; and
     (ii) the Company shall not be required to effect any such registration
     unless at least $5 million of Registrable Securities are to be sold in such
     registration (with such amount being determined based on the market price
     of the Common Stock on the date of the initiating Holder(s) request). If
     any registration pursuant to this Section 1.2 is in the form of an
     underwritten offering, the Company will select and obtain the investment
     banker or investment bankers and manager or managers that will administer
     the offering, which investment bankers must offer terms which are (together
     with all Holders proposing to distribute Registrable Securities through
     such underwriting) enter into an underwriting agreement, containing usual
     and customary terms, with the managing underwriter selected for such
     underwriting. If any holder of Registrable Securities disapproves of the
     terms of the underwriting, such person may elect to withdraw therefrom by
     written notice to the Company and the managing underwriter. The Registrable
     Securities to withdrawn shall also be withdrawn from registration.

         (d) If any registration statement under this Section 1.2 is not
     declared effective (except for the reasons specified in Section 1.9 below
     and except as a result of Holders withdrawing Registration Securities),
     then the holders of Registrable Securities may request an additional
     registration under this Section 1.2.

         (e) No registrations effected under this Section 1.2 shall relieve the
     Company of its obligations to effect any registrations under, and pursuant
     to the terms of, Section 1.3 and 1.4 hereof.

     1.3 S-3 Registrations.

         (a) Once the Company is eligible to effect a registration of its
     securities under Form S-3 (or successor form), the Holders will have the
     right to request and have effected (but only one registration per twelve
     month period) registrations of Registrable Securities on Form S-3 as long
     as the aggregate proposed offering price is not less $3 million for any
     such registration. Upon written request of Holders holding at least $3
     million of Registrable Securities, the Company will promptly notify in
     writing all other Holders of Registrable Securities of such request, which
     Holders shall within twenty days following such notice from the Company,
     notify the Company in writing whether such persons desire to have
     Registrable Securities held by them included in such offering. Following
     the expiration of such twenty day period, the Company will use all
     reasonable efforts to cause the registration of all Registrable Securities
     proposed to be included in the offering on Form S-3 or such successor form
     to the extent so requested. Notwithstanding the above, the Company shall
     not be required under this Section 1.3 to include any of the Holders'
     Registrable Securities in any offering on Form S-3 which involves an
     underwriting unless such Holders accept the terms of such underwriting as
     agreed upon between the Company and the underwriters selected by it.

         (b) Notwithstanding anything in this Section 1.3 to the contrary, the
     Company shall not be obligated to prepare or file any registration
     statement pursuant to this Section 1.3 or to prepare or file any amendment
     or supplement thereto, at any time when the Company, in the good faith
     judgment of its Board of Directors, reasonably believes that the filing
     thereof at the time requested, or the offering of securities pursuant
     thereto, (i) would materially adversely affect a pending or proposed public
     offering of the Company's securities, or an acquisition, merger,
     recapitalization, consolidation, reorganization or similar transaction,
     negotiations, discussions or pending proposals with respect thereto or (ii)
     would materially adversely affect the business or prospects of the Company
     in view of the disclosures that may be required thereby of information
     about the business, assets, liabilities or operations of






                                      A-2

     the Company not theretofore disclosed; provided, however, that the filing
     of a registration statement, or any supplement or amendment thereto, by the
     Company may be deferred pursuant to this Section 1.3 for no longer than 180
     days (but only once in every twelve month period) after the delivery of
     such demand notice.

     1.4 Piggyback Registration. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for stockholders other than the Holders) any of its Common Stock
or other securities under the Act in connection with the public offering of such
securities solely for cash (other than an initial public offering, registration
relating solely to the sale of securities to participants in a Company stock
option, stock purchase or similar employee benefit plan, a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities (including Form S-4 or any form substitution thereof) or
a registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities which are also being registered or a
SEC Rule 145 transaction), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within twenty days after mailing of such notice by the Company, the
Company shall, subject to the provisions of Section 1.8, use all reasonable
efforts to cause to be registered under the Act and any applicable state
securities laws all of the Registrable Securities that each such Holder has
requested to be registered.

     1.5 Obligations of the Company. Whenever under this Section 1 the Company
effects the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

         (a) Prepare and file with the SEC on any appropriate form a
     registration statement with respect to the Registrable Securities proposed
     to be registered and use its best efforts to cause such registration
     statement to become effective;

         (b) Unless such registration is a firm commitment underwriting, prepare
     and file with the SEC such amendments (including post-effective amendments)
     and supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective and to comply with the provisions of the Act with
     respect to the disposition of all Registrable Securities and other
     securities covered by such registration statement for a period of 180 days.

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

         (d) Use its best efforts to register or qualify all Registrable
     Securities and other securities covered by such registration statement
     under such other securities or "blue sky" laws of such jurisdictions as the
     underwriter or such sellers (not to exceed ten jurisdictions) shall
     reasonably request and do any and all other acts and things as may be
     reasonably necessary to consummate the disposition in such jurisdictions of
     the Registrable Securities covered by such registration statement, except
     that the Company shall not for any such purpose be required to qualify
     generally to do business as a foreign corporation in any jurisdiction
     wherein it is not so qualified, or to subject itself to taxation in respect
     of doing business in any such jurisdiction, or to consent to general
     service of process in any such jurisdiction.

         (e) Immediately notify each seller of Registrable Securities covered by
     such registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the Act, of the happening of any event as
     a result of which the prospectus included in such registration statement,
     as then in effect, includes an untrue statement of a material fact or omits
     to state any material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances then existing or if its is necessary, in the opinion of
     counsel to the Company, to amend or supplement such prospectus to comply
     with law, and at the request of any such seller prepare and to such seller
     a reasonable number of copies of a supplement to or any amendment of such
     prospectus as may be necessary so that, as thereafter delivered to the
     purchasers of such Registrable Securities, such prospectus shall not
     include an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances then existing and
     shall otherwise comply in all material respects with law and so that such
     prospectus, as amended or supplemented, will comply with law.


                                      A-3

<PAGE>   12



         (f) Otherwise use its best efforts to comply with all applicable rules
     and regulations of the SEC, any make available to its securityholders, as
     soon as reasonably practicable, an earnings statement covering the period
     of at least twelve (12) months, beginning with the first month of the first
     fiscal quarter after the effective date of such registration statement,
     which earnings statement shall satisfy the provisions of Section 11 (a) of
     the Act.

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

         (h) Notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Act of the happening of any event as a
     result of which the prospectus included in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing.

         (i) Cause all such Registrable Securities registered pursuant hereunder
     to be listed on each securities exchange or automated trading system on
     which similar securities issued by the Company are then listed.

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

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

     1.7 Expenses of Registration. All expenses incurred in connection with
registrations, filings or qualifications pursuant to this Section 1, in
connection with one demand registration, all piggyback registrations and all S-3
registrations including, without limitation, all registration, filing and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company (but excluding underwriter's commissions and fees and
any fees of others employed by a selling Holder) shall be borne by the Company.

     1.8 Underwriting Requirements; Cut-backs.

         (a) In connection with any offering involving an underwriting of shares
     of the Company's capital stock, the Company shall not be required to
     include any Holders' Registrable Securities in such underwriting unless
     they accept the terms of the underwriting as agreed upon between the
     Company and the underwriters selected by it (or by other persons entitled
     to select the underwriters), and then only in such quantity as the
     underwriters determine in their sole discretion will not materially
     jeopardize or in any way reduce the success of the offering by the Company.

         (b) The Company has previously granted "piggyback" registration rights
     to certain of its securityholders (the "Other Holders"). Notwithstanding
     any thing in this Section 1 to the contrary, in the event of any request
     for registration hereunder, the Company shall provide each Other Holder the
     notice required with respect to their registration rights and will allow
     such Other Holders to participate in any such registration to the extent of
     such registration rights; it being acknowledged and agreed that if the
     total amount of securities, including Registrable Securities, requested by
     security holders to be included in such offering exceeds the amount of
     securities that the underwriters determine in their sole discretion is
     compatible with the success of the offering (excluding any securities to be
     offered by the Company), then the Company shall be required to include in
     the offering only that number of such securities, including Registrable
     Securities, which the underwriters determine in their sole discretion will
     not jeopardize the success of the offering (the securities so included to
     be apportioned pro rata among the selling security holders (including
     Holders) according to the total amount of securities entitled to be
     included therein owned by each selling shareholder (including Holders) or
     in such other proportions as shall mutually be agreed to by such selling
     shareholders (including Holders)).

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

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

         (a) To the extent permitted by law, the Company will indemnify and hold
     harmless each Holder, any underwriter (as defined in the Act) for such
     Holder and each person, if any, who controls such Holder or underwriter
     within the meaning of the Act or the 1934 Act against any losses, claims,
     damages, or liabilities, joint or several) to which they may become subject
     under the Act, the 1934 Act or other federal or state law, insofar as such
     losses, claims, damages, or liabilities (or actions in respect thereof)
     arise out of or are based upon any of the following statements, omissions
     or violations (collectively a "Violation"): (i) any untrue statement or
     alleged untrue statement of a material fact contained in such registration
     statement, including any preliminary prospectus or final prospectus
     contained therein or any amendments or supplements thereto, (ii) the
     omission or alleged omission to state therein a material fact required to
     be stated therein, or necessary to make the statements therein not
     misleading, or (iii) any violation or alleged violation by the Company of
     the Act, the 1934 Act, any state securities law or any rule or regulation
     promulgated under the, the 1934 Act or any state securities law; and,
     subject to subsection 1.10 (c) below, the Company will pay to each such
     Holder, underwriter or controlling person, as incurred, any legal or other
     expenses reasonably incurred by them in connection with investigating or
     defending any such loss, claim, damage, liability, or action; provided,
     however, that the indemnity agreement contained in this subsection 1.10(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 reasonably 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 any such Holder, underwriter or controlling person.

         (b) 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 has signed the registration statement, each person, if any, who
     controls the Company within the meaning of the Act, any underwriter, any
     other Holder selling securities in such registration statement and any
     controlling person of any such underwriter or other Holder, and any agent
     of the Company, against any losses, claims, damages, or liabilities joint
     or several) to which any of the foregoing persons may become subject, under
     the Act, the 1934 Act or other federal or state law, insofar as such
     losses, claims, damages, or liabilities (or actions in respect thereto)
     arise out of or are based upon any Violation, in each case to the extent
     (and only to the extent) that such Violation occurs in reliance upon and in
     conformity with written information furnished by such Holder expressly for
     use in connection with such registration; and each such Holder will pay, as
     incurred, any legal or other expenses reasonably incurred by any person
     intended to be indemnified pursuant to this subsection 1.10(b), in
     connection with investigating or defending any such loss, claim, damage,
     liability, or action; provided, however, that the indemnity agreement
     contained in this subsection 1.10(b) shall not apply to amounts paid in
     settlement of any such loss, claim, damage, liability or action if such
     settlement is effected without the consent of the Holder, which consent
     shall not be reasonably withheld; provided, that, in no event shall any
     indemnity under this subsection 1.10(b) exceed the gross proceeds from the
     offering received by such Holder.

         (c) Promptly after receipt by an indemnified party under this Section
     1.10 of notice of the commencement of any action (including any
     governmental action), such indemnified party will, if a claim in respect
     thereof is to be made against any indemnifying party under this Section
     1.10, deliver to the indemnifying party a written notice of the
     commencement thereof and the indemnifying party shall have the right to
     participate in, and, to the extent the indemnifying party so desires,
     jointly with any other indemnifying party receiving similar notice, to
     assume the defense thereof with counsel reasonably satisfactory to the
     parties; provided, however, that an indemnified party (together with all
     other indemnified party which may be represented without conflict by one
     counsel) shall have the right to retain one separate counsel, with the fees
     and expenses to be paid by the indemnifying party, if representation of
     such indemnified party by the counsel retained by the indemnifying party
     would be inappropriate due to actual or potential differing interests
     between such indemnified party and any other party represented by such
     counsel in such proceeding; otherwise, the indemnified party shall be
     responsible for the fees and expenses of its counsel. The failure to
     deliver written notice to the indemnifying party within a reasonable time
     of the commencement of any such action, if prejudicial to its ability to
     defend such action, shall relieve such indemnifying party of any liability
     to the indemnified party under this Section 1.10.

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

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

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

     1.11 Assignment of Registration Rights. The registration rights of the
Holders under this Section 1 may be assigned (but only with all related
obligations) by a Holder to a transferee or assignee of such securities who
purchases from such Holder at least 10,000 shares of Registrable Securities
(subject to appropriate adjustment for stock splits, stock dividends,
combinations and other recapitalizations), provided: (a) the Company is promptly
after such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
piggyback registration rights are being assigned; (b) such transferee or
assignee agrees in writing to be bound by and subject to the terms and
conditions of this Agreement, including without limitation the provisions of
Section 1.12 below; and (c) such assignment shall be effective only if
immediately following such transfer the further disposition of such securities
by the transferee or assignee is restricted under the Act.

     1.12 Lock-up Agreement. Each Holder hereby agrees that if requested by the
Company or the underwriters in any underwritten offering, such Holder shall not,
for the period of 180 days after the effective date of an underwritten public
offering of shares of Common Stock, without the prior written approval of the
Company or such underwriters (as the case may be), directly or indirectly, sell,
offer to sell, contract to sell (including without limitation, any short sale),
grant any option to purchase or otherwise transfer or dispose of any shares of
Common Stock underlying the Warrants legally or beneficially owned by such
Holder; provided, however, in the event of an initial public offering of Common
Stock, no request shall be necessary, with the consent of such Holder to the
above provisions in this Section 1.12 being hereby granted and accepted,
provided that if the managing underwriter in such initial public offering
requests that Holder execute and deliver a lock-up letter, Holder agrees to do
so, which lock-up letter shall be in such managing underwriter's customary form.
In order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

     1.13 Termination of Registration Rights. Notwithstanding anything in this
Section 1 to the contrary, no Holder shall be entitled to exercise any right
provided for in this Section 1: (i) at any time more than two (2) years
following the date after the Company becomes a Public Company or (ii) at such
time as such Holder is able to sell all of such Holder's Registrable Securities
in a single three-month period in compliance with Rule 144.

     1.14 Amendments and Waivers. Any term or provision of the registration
rights stated in this Section 1 may be amended and the observance of any term of
such rights may be waived (either generally or in a particular instance and
either retroactively or prospectively), only with the written consent of the
Company and the holders of at a majority of the Registrable Securities then
outstanding. Any amendment or waiver effected in accordance with this Section
1.13 shall be binding upon each holder of any Registrable Securities then
outstanding, each future holder of any Registrable Securities, and the Company.

         4.1 Authority. You have full power and authority to enter into this
Agreement and it constitutes your legal, valid and binding obligation,
enforceable in accordance with its terms.

         4.2 Purchase For Own Account. You are acquiring the Securities for your

distribution, or in connection with any distribution thereof you are able to (i)
bear the economic risk of your investment in the Securities, (ii) hold the

your investment.

         4.3 Investment Experience. You have the requisite knowledge and
experience in financial and business matters, including investments of this
type, to be capable of evaluating the merits and risks of an investment in the
Securities and of making an informed investment decision with respect thereto.

         4.4 Receipt Of Information. You have received from the Company all of
the information concerning the Company which you consider to be material in
making your investment decision, which information has been requested by you if
not already furnished by the Company. You have had full access to the books and

securities laws of any other jurisdiction, that they may not be resold or
transferred without compliance with the registration or qualification provisions

laws of any state or other jurisdiction.

                                   Appendix I
                               Registration Rights

1. Registration Rights. The Company covenants and agrees with you as follows:

     1.1 Definitions. For purposes of this Appendix I:

         (a) The term "Holder" means any person owning or having the right to
     acquire Registrable Securities or any assignee thereof in accordance with
     Section 1.11 hereof.

         (b) The term "1934 Act" shall mean the Securities Exchange Act of
     1934, as amended.

         (c) The term "Public Company" means a corporation which has a class of
     equity securities registered pursuant to Section 12 of the 1934 Act, or
     which is required to file periodic reports pursuant to Section 15(d) of the
     1934 Act.

         (d) The term "register," "registered," and "registration" refer to a
     registration effected by preparing and filing a registration statement or
     similar document in compliance with the Act, and the declaration or
     ordering of effectiveness of such registration statement or document.

         (e) The term "Registrable Securities" means (i) the shares of Common
     Stock issued or issuable upon the exercise of the Warrants and (ii) any
     Common Stock 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 the
     shares referenced in (i) above, excluding in all cases, however, any
     Registrable Securities (I) sold by a person in a transaction in which his
     rights under this Section 1 are not assigned (II) registered under the Act,
     the registration statement in connection therewith has been declared
     effective, and such shares have been disposed by such holder pursuant to
     such registration statement; provided, however, that in either case of (i)
     or (ii) above, any such securities shall cease to be Registrable Securities
     if the registration rights granted hereunder are not transferred in
     accordance with the provisions of Section 1.11 below.

         (f) The number of shares of "Registrable Securities then outstanding"
     shall be determined by the number of shares of Common Stock issued or
     issuable upon exercise of the Warrants which are Registrable Securities.

         (g)  The term "SEC" shall mean the Securities and Exchange Commission.

         (h) All other capitalized terms used herein which are not defined
     herein shall have the meaning given elsewhere in this Agreement.

     1.2 Lock-up Agreement. Each Holder hereby agrees that if requested by the
Company or the underwriters in any underwritten offering, such Holder shall not,
for the period of 180 days after the effective date of an underwritten public
offering of shares of Common Stock, without the prior written approval of the
Company or such underwriters (as the case may be), directly or indirectly, sell,
offer to sell, contract to sell (including without limitation, any short sale),
grant any option to purchase or otherwise transfer or dispose of any shares of
Common Stock underlying the Warrants legally or beneficially owned by such
Holder; provided, however, in the event of an initial public offering of Common
Stock, no request shall be necessary, with the consent of such Holder to the
above provisions in this Section 1.2 being hereby granted and accepted, provided
that if the managing underwriter in such initial public offering requests that
Holder execute and deliver a lock-up letter, Holder agrees to do so, which
lock-up letter shall be in such managing underwriter's customary form. In order
to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

     1.3 S-3 Registrations.

         (a) Once the Company is eligible to effect a registration of its
     securities under Form S-3 (or successor form), the Holders will have the
     right to request and have effected (but only one registration per twelve
     month period) registrations of Registrable Securities on Form S-3 as long
     as the aggregate proposed offering price is not less $3 million for any
     such registration. Upon written request of Holders holding at least $3
     million of Registrable Securities, the Company will promptly notify in
     writing all other Holders of Registrable Securities of such request, which
     Holders shall within twenty days following such notice from the Company,
     notify the Company in writing whether such persons desire to have
     Registrable Securities held by them included in such offering. Following
     the expiration of such twenty day period, the Company will use all
     reasonable efforts to cause the registration of all Registrable Securities
     proposed to be included in the offering on Form S-3 or such successor form
     to the extent so requested. Notwithstanding the above, the Company shall
     not be required under this Section 1.3 to include any of the Holders'
     Registrable Securities in any offering on Form S-3 which involves an
     underwriting unless such Holders accept the terms of such underwriting as
     agreed upon between the Company and the underwriters selected by it.

         (b) Notwithstanding anything in this Section 1.3 to the contrary, the
     Company shall not be obligated to prepare or file any registration
     statement pursuant to this Section 1.3 or to prepare or file any amendment
     or supplement thereto, at any time when the Company, in the good faith
     judgment of its Board of Directors, reasonably believes that the filing
     thereof at the time requested, or the offering of securities pursuant
     thereto, (i) would materially adversely affect a pending or proposed public
     offering of the Company's securities, or an acquisition, merger,
     recapitalization, consolidation, reorganization or similar transaction,
     negotiations, discussions or pending proposals with respect thereto or (ii)
     would materially adversely affect the business or prospects of the Company
     in view of the disclosures that may be required thereby of information
     about the business, assets, liabilities or operations of the Company not
     theretofore disclosed; provided, however, that the filing of a registration
     statement, or any supplement or amendment thereto, by the Company may be
     deferred pursuant to this Section 1.3 for no longer than 180 days (but only
     once in every twelve month period) after the delivery of such demand
     notice.

     1.4 Piggyback Registration. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for stockholders other than the Holders) any of its Common Stock
or other securities under the Act in connection with the public offering of such
securities solely for cash (other than an initial public offering, registration
relating solely to the sale of securities to participants in a Company stock
option, stock purchase or similar employee benefit plan, a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities (including Form S-4 or any form substitution thereof) or
a registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities which are also being registered or a
SEC Rule 145 transaction), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within twenty days after mailing of such notice by the Company, the
Company shall, subject to the provisions of Section 1.8, use all reasonable
efforts to cause to be registered under the Act and any applicable state
securities laws all of the Registrable Securities that each such Holder has
requested to be registered.

     1.5 Obligations of the Company. Whenever under this Section 1 the Company
effects the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

         (a) Prepare and file with the SEC on any appropriate form a
     registration statement with respect to the Registrable Securities proposed
     to be registered and use its best efforts to cause such registration
     statement to become effective;

         (b) Unless such registration is a firm commitment underwriting, prepare
     and file with the SEC such amendments (including post-effective amendments)
     and supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective and to comply with the provisions of the Act with
     respect to the disposition of all Registrable Securities and other
     securities covered by such registration statement for a period of 180 days.


                                       A-2

<PAGE>   11



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

         (d) Use its best efforts to register or qualify all Registrable
     Securities and other securities covered by such registration statement
     under such other securities or "blue sky" laws of such jurisdictions as the
     underwriter or such sellers (not to exceed ten jurisdictions) shall
     reasonably request and do any and all other acts and things as may be
     reasonably necessary to consummate the disposition in such jurisdictions of
     the Registrable Securities covered by such registration statement, except
     that the Company shall not for any such purpose be required to qualify
     generally to do business as a foreign corporation in any jurisdiction
     wherein it is not so qualified, or to subject itself to taxation in respect
     of doing business in any such jurisdiction, or to consent to general
     service of process in any such jurisdiction.

         (e) Immediately notify each seller of Registrable Securities covered by
     such registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the Act, of the happening of any event as
     a result of which the prospectus included in such registration statement,
     as then in effect, includes an untrue statement of a material fact or omits
     to state any material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances then existing or if its is necessary, in the opinion of
     counsel to the Company, to amend or supplement such prospectus to comply
     with law, and at the request of any such seller prepare and to such seller
     a reasonable number of copies of a supplement to or any amendment of such
     prospectus as may be necessary so that, as thereafter delivered to the
     purchasers of such Registrable Securities, such prospectus shall not
     include an untrue statement of a material fact or omit to state a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances then existing and
     shall otherwise comply in all material respects with law and so that such
     prospectus, as amended or supplemented, will comply with law.

         (f) Otherwise use its best efforts to comply with all applicable rules
     and regulations of the SEC, any make available to its securityholders, as
     soon as reasonably practicable, an earnings statement covering the period
     of at least twelve (12) months, beginning with the first month of the first
     fiscal quarter after the effective date of such registration statement,
     which earnings statement shall satisfy the provisions of Section 11 (a) of
     the Act.

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

         (h) Notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Act of the happening of any event as a
     result of which the prospectus included in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing.

         (i) Cause all such Registrable Securities registered pursuant hereunder
     to be listed on each securities exchange or automated trading system on
     which similar securities issued by the Company are then listed.

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

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

<PAGE>   12



     1.7 Expenses of Registration. All expenses incurred in connection with
registrations, filings or qualifications pursuant to this Section 1 in
connection with all piggyback registrations and all S-3 registrations including,
without limitation, all registration, filing and qualification fees, printers'
and accounting fees, fees and disbursements of counsel for the Company (but
excluding underwriter's commissions and fees and any fees of others employed by
a selling Holder) shall be borne by the Company.

     1.8 Underwriting Requirements; Cut-backs.

         (a) In connection with any offering involving an underwriting of shares
     of the Company's capital stock, the Company shall not be required to
     include any Holders' Registrable Securities in such underwriting unless
     they accept the terms of the underwriting as agreed upon between the
     Company and the underwriters selected by it (or by other persons entitled
     to select the underwriters), and then only in such quantity as the
     underwriters determine in their sole discretion will not materially
     jeopardize or in any way reduce the success of the offering by the Company.

         (b) The Company has previously granted "piggyback" registration rights
     to certain of its securityholders (the "Other Holders"). Notwithstanding
     any thing in this Section 1 to the contrary, in the event of any request
     for registration hereunder, the Company shall provide each Other Holder the
     notice required with respect to their registration rights and will allow
     such Other Holders to participate in any such registration to the extent of
     such registration rights; it being acknowledged and agreed that if the
     total amount of securities, including Registrable Securities, requested by
     security holders to be included in such offering exceeds the amount of
     securities that the underwriters determine in their sole discretion is
     compatible with the success of the offering (excluding any securities to be
     offered by the Company), then the Company shall be required to include in
     the offering only that number of such securities, including Registrable
     Securities, which the underwriters determine in their sole discretion will
     not jeopardize the success of the offering (the securities so included to
     be apportioned pro rata among the selling security holders (including
     Holders) according to the total amount of securities entitled to be
     included therein owned by each selling shareholder (including Holders) or
     in such other proportions as shall mutually be agreed to by such selling
     shareholders (including Holders)).

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

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

         (a) To the extent permitted by law, the Company will indemnify and hold
     harmless each Holder, any underwriter (as defined in the Act) for such
     Holder and each person, if any, who controls such Holder or underwriter
     within the meaning of the Act or the 1934 Act against any losses, claims,
     damages, or liabilities, joint or several) to which they may become subject
     under the Act, the 1934 Act or other federal or state law, insofar as such
     losses, claims, damages, or liabilities (or actions in respect thereof)
     arise out of or are based upon any of the following statements, omissions
     or violations (collectively a "Violation"): (i) any untrue statement or
     alleged untrue statement of a material fact contained in such registration
     statement, including any preliminary prospectus or final prospectus
     contained therein or any amendments or supplements thereto, (ii) the
     omission or alleged omission to state therein a material fact required to
     be stated therein, or necessary to make the statements therein not
     misleading, or (iii) any violation or alleged violation by the Company of
     the Act, the 1934 Act, any state securities law or any rule or regulation
     promulgated under the, the 1934 Act or any state securities law; and,
     subject to subsection 1.10 (c) below, the Company will pay to each such
     Holder, underwriter or controlling person, as incurred, any legal or other
     expenses reasonably incurred by them in connection with investigating or
     defending any such loss, claim, damage, liability, or action; provided,
     however, that the indemnity agreement contained in this subsection 1.10(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 reasonably 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 any such Holder, underwriter or controlling person.

         (b) 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 has signed the registration statement, each person, if any, who
     controls the Company within the meaning of the Act, any underwriter, any
     other Holder selling securities in such registration statement and any
     controlling person of any such underwriter or other Holder, and any agent
     of the Company, against any losses, claims, damages, or liabilities joint
     or several) to which any of the foregoing persons may become subject, under
     the Act, the 1934 Act or other federal or state law, insofar as such
     losses, claims, damages, or liabilities (or actions in respect thereto)
     arise out of or are based upon any Violation, in each case to the extent
     (and only to the extent) that such Violation occurs in reliance upon and in
     conformity with written information furnished by such Holder expressly for
     use in connection with such registration; and each such Holder will pay, as
     incurred, any legal or other expenses reasonably incurred by any person
     intended to be indemnified pursuant to this subsection 1.10(b), in
     connection with investigating or defending any such loss, claim, damage,
     liability, or action; provided, however, that the indemnity agreement
     contained in this subsection 1.10(b) shall not apply to amounts paid in
     settlement of any such loss, claim, damage, liability or action if such
     settlement is effected without the consent of the Holder, which consent
     shall not be reasonably withheld; provided, that, in no event shall any
     indemnity under this subsection 1.10(b) exceed the gross proceeds from the
     offering received by such Holder.

         (c) Promptly after receipt by an indemnified party under this Section
     1.10 of notice of the commencement of any action (including any
     governmental action), such indemnified party will, if a claim in respect
     thereof is to be made against any indemnifying party under this Section
     1.10, deliver to the indemnifying party a written notice of the
     commencement thereof and the indemnifying party shall have the right to
     participate in, and, to the extent the indemnifying party so desires,
     jointly with any other indemnifying party receiving similar notice, to
     assume the defense thereof with counsel reasonably satisfactory to the
     parties; provided, however, that an indemnified party (together with all
     other indemnified party which may be represented without conflict by one
     counsel) shall have the right to retain one separate counsel, with the fees
     and expenses to be paid by the indemnifying party, if representation of
     such indemnified party by the counsel retained by the indemnifying party
     would be inappropriate due to actual or potential differing interests
     between such indemnified party and any other party represented by such
     counsel in such proceeding; otherwise, the indemnified party shall be
     responsible for the fees and expenses of its counsel. The failure to
     deliver written notice to the indemnifying party within a reasonable time
     of the commencement of any such action, if prejudicial to its ability to
     defend such action, shall relieve such indemnifying party of any liability
     to the indemnified party under this Section 1.10.

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

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

rights stated in this Section 1 may be amended and the observance of any term of

either retroactively or prospectively), only with the written consent of the
Company and the holders of at a majority of the Registrable Securities then
outstanding. Any amendment or waiver effected in accordance with this Section
1.13 shall be binding upon each holder of any Registrable Securities then

($_____________), together with interest accrued thereon (calculated on the
basis of a 365-day year) at a rate of thirteen percent (13%) per annum from the
date hereof until the date that this Note is paid in full provided, however,
that such interest rate shall increase to a rate of eighteen percent ( 18%) per
annum upon the occurrence, and during the continuation, of an Event of Default
(as defined below). All payments on this Note shall be due and payable in lawful
money of the United States of America.

     This Note is one of a series of promissory notes of the Company styled "13%
Bridge Promissory Note" in the aggregate amount not to exceed $5,000,000 (plus
an over-allotment option not to exceed $1,000,000), which are being issued from
time to time prior to June 30, 1999, subject to extension at the option of Maker
(collectively, the "Bridge Notes").


     1. Principal and Interest Payments. The principal of and interest on this
Note shall be due and payable on July 31, 2000; provided, however, that the
principal of and accrued interest on, this Note must be prepaid in whole (i)
upon the consummation of a Public Offering (as hereinafter defined), (ii) upon
the consolidation or merger of Maker with or into any other corporation or
entity pursuant to which Maker, or its affiliate, is not the surviving entity,

principal or interest, shall be made by Maker to the holder hereof on the date
specified or provided herein and shall be delivered by means of certified or
cashiers' check or wire transfer of immediately available funds to an account
specified by the holder hereof. Whenever payment hereunder shall be due on a day

thereof shall be extended to the next succeeding Business Day. If the date for
any payment is extended by operation of law or otherwise, interest thereon shall
be payable for such extended time. "Business Day" means every day which is not a
Saturday, Sunday or legal holiday.

payment of principal of and interest on this Note shall be subordinate and
junior to the prior payment of the indebtedness of Maker: (a) owed to Sirrom
Capital Corporation and NationsBank, N.A., and their respective successors and
assigns (as such indebtedness may be renewed, deferred, extended, refunded,
amended or modified from time to time); and (b) hereafter created constituting

payment or distribution shall be held in trust for the holders of the Senior
Indebtedness, and shall be immediately delivered to such holders in the same
form as received.

     5. Events of Default. The following shall constitute events of default
("Events of Default") hereunder:

          (a) failure of Maker to make any payment on this Note as and when
the same becomes due and payable in accordance with the terms hereof;

          (b) failure of Maker to perform any other covenant contained herein
if the same has continued for thirty (30) days after written notice specifying
such default has been delivered to Maker by Payee;

          (c) the occurrence of any event of default under any Bridge Note or
under the Senior Indebtedness, which event of default is not cured within any
applicable cure period and in the case of Senior Indebtedness, for which the
holder of such Senior Indebtedness commences legal action against Maker to
collect the Senior Indebtedness;

          (d) if Maker makes an assignment for the benefit of creditors or
petitions or applies for the appointment of a liquidator, receiver or custodian
(or similar official) of it or of any substantial part of its assets, or if
Maker commences any proceeding or case relating to it under the Bankruptcy Code
or any other bankruptcy, reorganization, arrangement, insolvency, readjustment
<PAGE>   3


of debt, dissolution or liquidation or similar law of any jurisdiction, or takes
any action to authorize any of the foregoing; or

          (e) if any petition or application of the type described in
subparagraph (e) immediately above is filed or if any such proceeding or case
described in subparagraph (e) is commenced against Maker and is not dismissed
within sixty (60) days, or if Maker indicates its approval thereof, consents
thereto or acquiesces therein, or if an order is entered appointing any such
liquidator or receiver or custodian (or similar official), or adjudicating Maker
bankrupt or insolvent, or approving a petition in any such proceeding or if a
decree or order for relief is entered in respect of Maker in an involuntary case

any jurisdiction.

     In the event any one or more of the Events of Default specified above
occurs and is continuing, the holder of this Note may (i) accelerate the
maturity of this Note with notice to Maker at which time all such amounts shall
be immediately, due and payable, (ii) proceed to protect and enforce its rights
either by suit in equity or by action at law, or by other appropriate
proceedings, whether for the specific performance of any covenant or agreement
contained in this Note or in aid of the exercise of any power or right granted
by this Note, or (iii) enforce any other legal or equitable right of the holder
of this Note.

     6. Delay or Omission Not Waiver. No delay or omission on the part of the
holder of this Note in the exercise of any power, remedy or right under this
Note, or under any other instrument executed pursuant hereto, shall operate as a
waiver thereof, nor shall a single or partial exercise of any such power or
right preclude any other or further exercise thereof or the exercise of any
other right or power hereunder.

     7. Waiver. Any term, covenant, agreement or condition of this Note may,
only with the written consent of Maker and Payee, be amended or compliance
therewith may be waived (either generally or in a particular instance and either
retroactively or prospectively), altered, modified or amended.

     8. Attorneys' Fees and Costs. In the event an Event of Default shall occur,
and in the event that thereafter this Note is placed in the hands of an attorney
for collection, or in the event this Note is collected in whole or in part
through legal proceedings of any nature, then and in any such case Maker
promises to pay all costs of collection, including, but not limited to,
reasonable attorneys' fees and court costs incurred by the holder hereof on
account of such collection, whether or not suit is filed.

     9. Successors and Assign. All of the covenants, stipulations, promises and
agreements in this Note made by Maker and Payee (by virtue of its acceptance of
this Note) shall bind its successors and assigns, whether so expressed or not.

from time to time in effect.
<PAGE>   4

In no way, nor in any event or contingency (including but not limited to
prepayment, default, demand for payment, or acceleration of the maturity of any
obligation), shall the rate of interest taken, reserved, contacted for, charged
or received under this Note exceed the highest lawful interest rate permitted
under applicable law. If the holder of this Note shall ever receive anything of
value which is characterized as interest under applicable law and which would
apart from this provision be in excess of the highest lawful interest rate
permitted under applicable law, an amount equal to the amount which would have
been excessive interest shall, without penalty, be applied to the reduction of
the principal amount owing on this Note in the inverse order of its maturity and
not to the payment of interest, or refunded to Maker or the other payor thereof
if and to the extent such amount which would have been excessive exceeds such
unpaid principal. All interest paid or agreed to be paid to the holder hereof
shall, to the extent permitted by applicable law, be amortized, prorated,
allocated and spread throughout the full stated term (including any renewal or
extension) of this Note so that the amount of interest on account of such
obligation does not exceed the maximum permitted by applicable law. As used in
this Section, the term "applicable law" shall mean the laws of the State of
Delaware or the federal laws of the United States, whichever laws allow the
greater interest, as such laws now exist or may be changed or amended or come
into effect in the future.

     11. Governing Law. This Note shall be governed by and construed in
accordance with the substantive laws (but not the rules governing conflicts of
laws) of the State of Delaware.

     12. Notice. All notices, demands or requests provided for or permitted to
be given under this Note must be in writing, and shall be given and be deemed
received as set forth in the Purchase Agreement.

     13. Severability. In case any one or more of the provisions contained in
this Note shall for any reason be held to be invalid, illegal or unenforceable
in any respect, such invalidity, illegality or unenforceability shall not affect
any other provision hereof.

     EXECUTED as of the date set forth above.

         1.2 Demand Registration.

                  (a) From and after January 1, 2001, the Holders of at least
         66 2/3% of the then outstanding Registrable Securities may notify the
         Company in writing that such Holders desire for the Company, to cause
         all or a portion of such notifying Holders' Registrable Securities to
         be registered for sale to the public under the Securities Act. Upon
         receipt of such written request, the Company will promptly notify in
         writing all other Holders of Registrable Securities of such request,
         which Holders shall within twenty days following such notice from the
         Company, notify the Company in writing whether such persons desire to
         have Registrable Securities held by them included in such offering. The
         Company will, promptly following the expiration of such twenty day
         period, prepare and file subject to the provisions of this Section 1,
         and use its best efforts to prosecute to effectiveness, in appropriate
         filing, with the SEC of a registration statement covering such
         Registrable Securities and the proposed sale or distribution thereof
         under the Securities Act.

                  (b) Notwithstanding anything in this Section 1.2 to the
         contrary, the Company shall not be obligated to prepare or File any
         registration statement pursuant to this Section 1.2 or to prepare or
         file any amendment or supplement thereto, at any time when the Company,
         in the good faith judgement of its Board of Directors, reasonably
         believes that the filing thereof at the time requested, or the offering
         of securities Pursuant thereto, (i) would materially, adversely affect
         a pending or proposed public offering of the Company's securities, or
         an acquisition, merger, recapitalization, consolidation, reorganization
         or similar transaction, negotiations, discussions or pending proposals
         with respect thereto or (ii) would materially adversely affect the
         business or prospects of the Company in view of the disclosures that
         may be required thereby, of information about the business, assets,
         liabilities or operations of the Company not theretofore disclosed;
         provided, however, that the filing of a registration statement, or any
         supplement or amendment thereto, by the Company may be deferred
         pursuant to this Section 1.2 for no longer than 180 days (but only once
         in every twelve month period) after the delivery of such demand notice.

                  (c) Notwithstanding anything in this Section 1.2 to the
         contrary: (i) the Company shall not be required to effect the
         registration of the Registrable Securities pursuant to this Section 1.2
         more than one time in any twelve month period and no more than three
         times in the aggregate; and (ii) the Company shall not be required to
         effect any such registration unless at least $10 million of Registrable
         Securities are to be sold in such registration (with such amount being
         determined based on the market price of the Common Stock on the date of
         the initiating Holder(s) request). If any registration pursuant to this
         Section 1.2 is in the form of an underwritten offering, the Company
         will select and obtain the investment banker or investment bankers and
         manager or managers that will administer the offering, which investment
         bankers must offer terms which are reasonably competitive in the
         marketplace for similar size companies and similar offerings. The
         Company shall (together with all Holders proposing to distribute
         Registrable Securities through such underwriting) enter into an
         underwriting agreement, containing usual and customary terms, with the
         managing

                                      A-2
<PAGE>   17

         underwriter selected for such underwriting. If any holder of
         Registrable Securities disapproves of the terms of the underwriting
         such person may elect to withdraw therefrom by written notice to the
         Company and the managing underwriter. The Registrable Securities so
         withdrawn shall also be withdrawn from registration.

                  (d) If any registration statement under this Section 1.2 is
         not declared effective (except for the reasons specified in Section 1.9
         below and except as a result of Holders withdrawing Registrable
         Securities), then the holders of Registrable Securities may request an
         additional registration under this Section 1.2.

                  (e) No registrations effected under this Section 1.2 shall
         relieve the Company of its obligations to effect any registrations
         under, and pursuant to the terms of. Sections 1.3 and 1.4 hereof.

         1.3 S-3 Registrations.

                  (a) Once the Company is eligible to effect a registration of
         its securities under Form S-3 (or successor form), the Holders will
         have the right to request and have effected (but only one registration
         per twelve month period) registrations of Registrable Securities on
         Form S-3 as long as the aggregate proposed offering price is not less
         $3 million for any such registration. Upon written request of Holders
         holding at least $3 million of Registrable Securities, the Company will
         promptly notify in writing all other Holders of Registrable Securities
         of such request, which Holders shalt within twenty days following such
         notice from the Company, notify the Company in writing whether such
         persons desire to have Registrable Securities held by them included in
         such offering. Following the expiration of such twenty day period. the
         Company will use all reasonable efforts to cause the registration of
         all Registrable Securities proposed to be included in the offering on
         Form S-3 or such successor form to the extent so requested.
         Notwithstanding the above, the Company shall not be required under this
         Section 1.3 to include any of the Holders' Registrable Securities in
         any offering, on Form S-3 which involves an underwriting unless such
         Holders accept the terms of such underwriting as agreed upon between
         the Company and the underwriters selected by it.

                  (b) Notwithstanding anything in this Section 1.3 to the
         contrary, the Company shall not be obligated to prepare or file any
         registration statement pursuant to this Section 1.3 or to prepare or
         file any amendment or supplement thereto, at any time when the Company,
         in the good faith judgment of its Board or Directors, reasonably
         believes that the filing thereof at the time requested, or the offering
         of securities pursuant thereto, (i) would materially adversely affect a
         pending or proposed public offering of the Company's securities, or an
         acquisition, merger, recapitalization, consolidation, reorganization or
         similar transaction, negotiations, discussions or pending proposals
         with respect thereto or (ii) would materially adversely affect the
         business or prospects of the Company in view of the disclosures that
         may be required thereby of information about the business, assets,
         liabilities

                                      A-3
<PAGE>   18

         or operations of the Company not theretofore disclosed; provided,
         however, that the filing of a registration statement, or any supplement
         or amendment thereto, by the Company may be deferred pursuant to this
         Section 1.3 for no longer than 180 days (but only once in every twelve
         month period) after the delivery of such demand notice.

         1.4 Piggyback Registration. If (but without any obligation to do so)
the Company proposes to register (including for this purpose a registration
effected by the Company for stockholders other than the Holders) any of its
Common Stock or other securities under the 1933 Act in connection with the
public offering of such securities solely for cash (other than an initial public
offering, registration relating solely to the sale of securities to participants
in a Company stock option, stock purchase or similar employee benefit plan, a
registration on any form which does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of the Registrable Securities (including Form S-4 or any form
substitution thereof) or a registration in which the only Common Stock being
registered is Common Stock issuable upon conversion of debt securities which are
also being registered or a SEC Rule 145 transaction), the Company shall, at such
time, promptly give each Holder written notice of such registration. Upon the
written request of each Holder given within twenty days after mailing of such
notice by the Company, the Company shall, subject to the provisions of Section
1.8, use all reasonable efforts to cause to be registered under the 1933 Act and
any applicable state securities laws all of the Registrable Securities that each
such Holder has requested to be registered.

         1.5 Obligations of the Company. Whenever under this Section 1 the
Company effects the registration of any Registrable Securities, the Company
shall, as expeditiously as reasonably possible:

                  (a) Prepare and file with the SEC on any appropriate form a
         registration statement with respect to the Registrable Securities
         proposed to be registered and use its best efforts to cause such
         registration statement to become effective;

                  (b) Unless such registration is a firm commitment
         underwriting; prepare and file with the SEC such amendments (including
         post-effective amendments) and supplements to such registration
         statement and the prospectus used in connection therewith as may be
         necessary to keep such registration statement effective and to comply
         with the provisions of the 1933 Act with respect to the disposition of
         all Registrable Securities and other securities covered by such
         registration statement for a period of 180 days.

                  (c) Furnish to the Holders 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

         Registrable Securities owned by them.

                  (d) Use its best efforts to register or qualify, all
         Registrable Securities and other securities covered by such

<PAGE>   19

         laws of such jurisdictions as the underwriter or such sellers (not to
         exceed ten jurisdictions) shall reasonably request and do any and all
         other acts and things as may be reasonably necessary to consummate the
         disposition in such jurisdictions of the Registrable Securities covered
         by such registration statement, except that the Company shall not for
         any such purpose be required to qualify generally to do business as a
         foreign corporation in any jurisdiction wherein it is not so qualified,
         or to subject itself to taxation in respect of doing business in any
         such jurisdiction, or to consent to general service of process in any
         such jurisdiction.

                  (e) Immediately notify each seller or Registrable Securities
         covered by such registration statement, 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 any material fact
         required to be stated therein or necessary to make the statements

         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading in the light of the circumstances then existing
         and shall otherwise comply in all material respects with law and so
         that such prospectus, as amended or Supplemented, will comply with law.

                  (f) Otherwise use its best efforts to comply with all
         applicable rules and regulations of the SEC, any make available to its
         securityholders, as soon as reasonably practicable, an earnings

         date of such registration statement, which earnings statement shall

         into and perform its obligations under an underwriting agreement, in
         usual and customary form, with the managing underwriter of such

         such registration statement at any time when a prospectus relating
         thereto is required to be delivered under the 1933 Act of the happening

         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.

         of shares of the Company's capital stock, the Company shall not be
         required to include any of the Holders' securities in such underwriting
         unless they accept the terms of the underwriting as agreed upon between
         the Company and the underwriters selected by it (or by other persons
         entitled to select the underwriters), and then only in such quantity as
         the underwriters determine in their sole discretion will not materially

         registration rights to certain of its security holders (the "Other
         Holders"). Notwithstanding any thing in this Section 1 to the contrary,

         shall provide each Other Holder the notice required with respect to
         their registration rights and will allow such Other Holders to
         participate in any such registration to the extent of such registration

         holders to be included in such offering exceeds the amount of
         securities sold other than by the Company that the underwriters
         determine in their sole discretion is compatible with the success of
         the Offering, then the Company shall be required to include in the
         offering only that number of such

<PAGE>   21

         securities, including Registrable Securities, which the underwriters
         determine in their sole discretion will not jeopardize the success of
         the offering (the securities so included to be apportioned pro rata
         among the selling security holders (including Holders) according to the
         total amount of securities entitled to be included therein owned by
         each selling shareholder (including Holders) or in such other
         proportions as shall mutually be agreed to by such selling shareholders
         (including Holders)).

         Company (which consent shall not be reasonably withheld), nor shall the
         Company be liable in any such case for any such loss, claim, damage,

         registration by any such Holder, underwriter or controlling person.

                  (b) To the extent permitted by law, each selling Holder will

                                      A-7
<PAGE>   22

         of the 1933 Act, any underwriter, any other Holder selling securities
         in such registration statement and any controlling person of any such
         underwriter or other Holder, and any agent of the Company, 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 Actor other federal or state law, insofar as such losses, claims,
         damages, or liabilities (or actions in respect thereto) arise out of or
         are based upon any Violation, in each case to the extent (and only to
         the extent) that such Violation occurs in reliance upon and in
         conformity with written information furnished by such Holder expressly
         for use in connection with such registration and each such Holder will
         pay, as incurred, any legal or other expenses reasonably incurred by
         any person intended to be indemnified pursuant to this subsection
         1.10(b), in connection with investigating or defending any such loss,
         claim, damage, liability, or action; provided, however, that the
         indemnity agreement contained in this subsection 1.10(b) shall not
         apply to amounts paid in settlement of any such loss, claim, damage,
         liability or action if such settlement is effected without the consent
         of the Holder, which consent shall not be reasonably withheld;
         provided, that, in no event shall any indemnity under this subsection
         1.10(b) exceed the gross proceeds from the offering received by such
         Holder.

                  (c) Promptly after receipt by an indemnified party under this
         Section 1.10 of notice of the commencement of any action (including any
         governmental action), such indemnified party will, if a claim in
         respect thereof is to be made against any indemnifying party under this
         Section 1.10, deliver to the indemnifying party a written notice of the
         commencement thereof and the indemnifying party shall have the right to
         participate in, and, to the extent the indemnifying party so desires,
         jointly with any other indemnifying party receiving similar notice, to
         assume the defense thereof with counsel reasonably satisfactory to the
         parties; provided, however, that an indemnified party (together with
         all other indemnified party which may be represented without conflict
         by one counsel) shall have the right to retain one separate counsel,
         with the fees and expenses to be paid by the indemnifying party, if
         representation of such indemnified party by the counsel retained by the
         indemnifying party would be inappropriate due to actual or potential
         differing interests between such indemnified party and any other party
         represented by such counsel in such proceeding; otherwise, the
         indemnified party shall be responsible for the fees and expenses of its
         counsel. The failure to deliver written notice to the indemnifying,
         party within a reasonable time of the commencement of any such action,
         if prejudicial to its ability to defend such action, shall relieve such
         indemnifying party of any liability to the indemnified party under this
         Section 1.10.

                  (d) Except as provided in the last sentence of subsection
         1.10(c) above, if the indemnification provided for in this Section 1.10
         is held by a court of competent jurisdiction to be unavailable to an
         indemnified party with respect to any loss, liability, claim, damage,
         or expense referred to therein, then the indemnifying party, in lieu of
         indemnifying such indemnified party hereunder, shall contribute to the
         amount paid or payable by such indemnified party as a result of such
         loss, liability, claim, damage, or expense in such proportion as is
         appropriate to reflect the relative fault of the indemnifying party on
         the one

                                      A-8
<PAGE>   23

         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.

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

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

         1.11 Assignment of Registration Rights. The registration rights of the
Holders under this Section 1 may be assigned (but only with all related
obligations) by a Holder to a transferee or assignee of such securities who
purchases from such Holder least 10,000 shares of Registrable Securities
(subject to appropriate adjustment for stock splits, stock dividends,
combinations and other recapitalizations), provided: (a) the Company is promptly
after such transfer, furnished with notice of the name and address of such
transferee or assignee and the securities with respect to which such piggyback
registration rights are being assigned: (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions or this
Agreement, including without limitation the provisions of Section 1.12 below;
and (c) such assignment shall be effective only immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the 1933 Act.

by the Company or the underwriters in any underwritten offering, Such Holder
shall not, for the period of 180 days after the effective date of an
underwritten public offering of shares of Common Stock, without the prior
written approval of the Company or such underwriters (as the case may be),
directly or indirectly, sell, offer to sell, contract to sell (including without
limitation, any short sale), grant any option to purchase or otherwise transfer
or dispose of any shares of Series C Stock or underlying Common Stock legally or
beneficially owned by such Holder; provided, however, in the event of an initial
public offering of Common Stock. no request shall be necessary, with the consent
of such Holder to the above provisions in this Section 1.12 being, hereby
granted and accepted. In order to enforce the foregoing covenant, the Company
may impose stop-transfer instructions with respect to the Registrable Securities
of each Holder (and the shares or securities of every, other person subject to
the foregoing restriction) until the end of such period.

         1.13 Termination of Registration Rights. Notwithstanding anything in
this Section 1 to the contrary, no Holder shall be entitled to exercise any
right provided for in this Section 1: (i) at any

                                      A-9
<PAGE>   24

time more than four (4) years following the date after the Company becomes a
Public Company or (ii) at such time as such Holder is able to sell all of such
Holder's Registrable Securities in a single three-month period in compliance
with Rule 144.

         1.14 Amendments and Waivers. Any term or provision of the registration
rights stated in this Section 1 may be amended and the observance of any term of
such rights may be waived (either generally or in a particular instance and
either retroactively or prospectively), only with the written consent of the
Company and the holders of at a majority of the Registrable Securities then
outstanding. Any amendment or waiver effected in accordance with this Section
1.14 shall be binding upon each holder of any Registrable Securities then

                                   Appendix I
                               Registration Rights

1.   Registration Rights.  The Company covenants and agrees with you as follows:

     1.1 Definitions. For purposes of this Appendix I:

          (a) The term "Holder" means any person owning or having the right to
     acquire Registerable Securities or any assignee thereof in accordance with
     Section 1.11 hereof.

          (b) The term "1934 Act" shall mean the Securities Exchange Act of
     1934, as amended.

          (c) The term "Public Company" means a corporation which has a class of
     equity securities registered pursuant to Section 12 of the 1934 Act, or
     which is required to file periodic reports pursuant to Section 15(d) of the
     1934 Act.

          (d) The term "register," "registered," and "registration" refer to a
     registration effected by preparing and filing a registration statement or
     similar document in compliance with the Act, and the declaration or
     ordering of effectiveness of such registration statement or document.

          (e) The term "Registerable Securities" means (i) the shares of Common
     Stock issued or issuable upon the exercise of the Series C Stock and the
     Warrants and (ii) any Common Stock 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 the shares referenced in (i) above, excluding in
     all cases, however, any Registerable Securities (I) sold by a person in a
     transaction in which his rights under this Section 1 are not assigned (II)
     registered under the Act, the registration statement in connection
     therewith has been declared effective, and such shares have been disposed
     by such holder pursuant to such registration statement; provided, however,
     that in either case of (i) or (ii) above, any such securities shall cease
     to be Registerable Securities if the registration rights granted hereunder
     are not transferred in accordance with the provisions of Section 1.11
     below.

          (f) The number of shares of "Registerable Securities then outstanding"
     shall be determined by the number of shares of Common Stock issued or
     issuable upon exercise of the Series C Stock and Warrants which are
     Registerable Securities.

          (g) The term "SEC" shall mean the Securities and Exchange Commission.

          (h) All other capitalized terms used herein which are not defined
     herein shall have the meaning given elsewhere in this Agreement.

     1.2 Demand Registration.

          (a) From and after January 1, 2001, the Holders of at least 66 2/3% of
     the then outstanding Registerable Securities may notify the Company in
     writing that such Holders desire for the Company to cause all or a portion
     of such notifying Holders' Registerable Securities to be registered for
     sale to the public under the Act. Upon receipt of such written request, the
     Company will promptly notify in writing all other Holders of Registerable
     Securities of such request, which Holders shall within twenty days
     following such notice from the Company, notify the Company in writing
     whether such persons desire to have Registerable Securities held by them
     included in such offering. The Company will, promptly following the
     expiration of such twenty day period, prepare and file subject to the
     provisions of this Section 1, and use its best efforts to prosecute to
     effectiveness, an appropriate filing with the SEC of a registration
     statement covering such Registerable Securities and the proposed sale or
     distribution thereof under the Act.

                                      A-1

<PAGE>   10



          (b) Notwithstanding anything in this Section 1.2 to the contrary, the
     Company shall not be obligated to prepare or file any registration
     statement pursuant to this Section 1.2 or to prepare or file any amendment
     or supplement thereto, at any time when the Company, in the good faith
     judgment of its Board of Directors, reasonably believes that the filing
     thereof at the time requested, or the offering of securities pursuant
     thereto, (i) would materially adversely affect a pending or proposed public
     offering of the Company's securities, or an acquisition, merger,
     recapitalization, consolidation, reorganization or similar transaction,
     negotiations, discussions or pending proposals with respect thereto or (ii)
     would materially adversely affect the business or prospects of the Company
     in view of the disclosures that may be required thereby of information
     about the business, assets, liabilities or operations of the Company not
     theretofore disclosed; provided, however, that the filing of a registration
     statement, or any supplement or amendment thereto, by the Company may be
     deferred pursuant to this Section 1.2 for no longer than 180 days (but only
     once in every twelve month period) after the delivery of such demand
     notice.

          (c) Notwithstanding anything in this Section 1.2 to the contrary: (i)
     the Company shall not be required to effect the registration of the
     Registerable Securities pursuant to this Section 1.2 more than one time;
     and (ii) the Company shall not be required to effect any such registration
     unless at least $5 million of Registerable Securities are to be sold in
     such registration (with such amount being determined based on the market
     price of the Common Stock on the date of the initiating Holder(s) request).
     If any registration pursuant to this Section 1.2 is in the form of an
     underwritten offering, the Company will select and obtain the investment
     banker or investment bankers and manager or managers that will administer
     the offering, which investment bankers must offer terms which are
     reasonably competitive in the marketplace for similar size companies and
     similar offerings. The Company shall (together with all Holders proposing
     to distribute Registerable Securities through such underwriting) enter into
     an underwriting agreement, containing usual and customary terms, with the
     managing underwriter selected for such underwriting. If any holder of
     Registerable Securities disapproves of the terms of the underwriting, such
     person may elect to withdraw therefrom by written notice to the Company and
     the managing underwriter. The Registerable Securities so withdrawn shall
     also be withdrawn from registration.

          (d) If any registration statement under this Section 1.2 is not
     declared effective (except for the reasons specified in Section 1.9 below
     and except as a result of Holders withdrawing Registerable Securities),
     then the holders of Registerable Securities may request an additional
     registration under this Section 1.2.

          (e) No registrations effected under this Section 1.2 shall relieve the
     Company of its obligations to effect any registrations under, and pursuant
     to the terms of, Sections 1.3 and 1.4 hereof.

     1.3 S-3 Registrations.

          (a) Once the Company is eligible to effect a registration of its
     securities under Form S-3 (or successor form), the Holders will have the
     right to request and have effected (but only one registration per twelve
     month period) registrations of Registerable Securities on Form S-3 as long
     as the aggregate proposed offering price is not less $3 million for any
     such registration. Upon written request of Holders holding at least $3
     million of Registerable Securities, the Company will promptly notify in
     writing all other Holders of Registerable Securities of such request, which
     Holders shall within twenty days following such notice from the Company,
     notify the Company in writing whether such persons desire to have
     Registerable Securities held by them included in such offering. Following
     the expiration of such twenty day period, the Company will use all
     reasonable efforts to cause the registration of all Registerable Securities
     proposed to be included in the offering on Form S-3 or such successor form
     to the extent so requested. Notwithstanding the above, the Company shall
     not be required under this Section 1.3 to include any of the Holders'
     Registerable Securities in any offering on Form S-3 which involves an
     underwriting unless such Holders accept the terms of such underwriting as
     agreed upon between the Company and the underwriters selected by it.

          (b) Notwithstanding anything in this Section 1.3 to the contrary, the
     Company shall not be obligated to prepare or file any registration
     statement pursuant to this Section 1.3 or to prepare or file any amendment
     or supplement thereto, at any time when the Company, in the good faith
     judgment of its Board of Directors, reasonably believes that the filing
     thereof at the time requested, or the offering of securities pursuant
     thereto, (i)


                                      A-2

<PAGE>   11

     would materially adversely affect a pending or proposed public offering of
     the Company's securities, or an acquisition, merger, recapitalization,
     consolidation, reorganization or similar transaction, negotiations,
     discussions or pending proposals with respect thereto or (ii) would
     materially adversely affect the business or prospects of the Company in
     view of the disclosures that may be required thereby of information about
     the business, assets, liabilities or operations of the Company not
     theretofore disclosed; provided, however, that the filing of a registration
     statement, or any supplement or amendment thereto, by the Company may be
     deferred pursuant to this Section 1.3 for no longer than 180 days (but only
     once in every twelve month period) after the delivery of such demand
     notice.

     1.4 Piggyback Registration. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for stockholders other than the Holders) any of its Common Stock
or other securities under the Act in connection with the public offering of such
securities solely for cash (other than an initial public offering, registration
relating solely to the sale of securities to participants in a Company stock
option, stock purchase or similar employee benefit plan, a registration on any
form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registerable Securities (including Form S-4 or any form substitution thereof) or
a registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities which are also being registered or a
SEC Rule 145 transaction), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within twenty days after mailing of such notice by the Company, the
Company shall, subject to the provisions of Section 1.8, use all reasonable
efforts to cause to be registered under the Act and any applicable state
securities laws all of the Registerable Securities that each such Holder has
requested to be registered.

     1.5 Obligations of the Company. Whenever under this Section 1 the Company
effects the registration of any Registerable Securities, the Company shall, as
expeditiously as reasonably possible:

          (a) Prepare and file with the SEC on any appropriate form a
     registration statement with respect to the Registerable Securities proposed
     to be registered and use its best efforts to cause such registration
     statement to become effective;

          (b) Unless such registration is a firm commitment underwriting,
     prepare and file with the SEC such amendments (including post-effective
     amendments) and supplements to such registration statement and the
     prospectus used in connection therewith as may be necessary to keep such
     registration statement effective and to comply with the provisions of the
     Act with respect to the disposition of all Registerable Securities and
     other securities covered by such registration statement for a period of 180
     days.

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

          (d) Use its best efforts to register or qualify all Registerable
     Securities and other securities covered by such registration statement
     under such other securities or "blue sky" laws of such jurisdictions as the
     underwriter or such sellers (not to exceed ten jurisdictions) shall
     reasonably request and do any and all other acts and things as may be
     reasonably necessary to consummate the disposition in such jurisdictions of
     the Registerable Securities covered by such registration statement, except
     that the Company shall not for any such purpose be required to qualify
     generally to do business as a foreign corporation in any jurisdiction
     wherein it is not so qualified, or to subject itself to taxation in respect
     of doing business in any such jurisdiction, or to consent to general
     service of process in any such jurisdiction.

          (e) Immediately notify each seller of Registerable Securities covered
     by such registration statement, at any time when a prospectus relating
     thereto is required to be delivered under the Act, of the happening of any
     event as a result of which the prospectus included in such registration
     statement, as then in effect, includes an untrue statement of a material
     fact or omits to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading in the light of the
     circumstances then existing or if its is necessary, in the

                                      A-3
<PAGE>   12

     opinion of counsel to the Company, to amend or supplement such prospectus
     to comply with law, and at the request of any such seller prepare and to
     such seller a reasonable number of copies of a supplement to or any
     amendment of such prospectus as may be necessary so that, as thereafter
     delivered to the purchasers of such Registerable Securities, such
     prospectus shall not include an untrue statement of a material fact or omit
     to state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing and shall otherwise comply in all material respects with law
     and so that such prospectus, as amended or supplemented, will comply with
     law.

          (f) Otherwise use its best efforts to comply with all applicable rules
     and regulations of the SEC, any make available to its securityholders, as
     soon as reasonably practicable, an earnings statement covering the period
     of at least twelve (12) months, beginning with the first month of the first
     fiscal quarter after the effective date of such registration statement,
     which earnings statement shall satisfy the provisions of Section 11 (a) of
     the Act.

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

          (h) Notify each Holder of Registerable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Act of the happening of any event as a
     result of which the prospectus included in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing.

          (i) Cause all such Registerable Securities registered pursuant
     hereunder to be listed on each securities exchange or automated trading
     system on which similar securities issued by the Company are then listed.

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

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

     1.7 Expenses of Registration. All expenses incurred in connection with
registrations, filings or qualifications pursuant to this Section 1, in
connection with one demand registration, all piggyback registrations and all S-3
registrations including, without limitation, all registration, filing and
qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company (but excluding underwriter's commissions and fees and
any fees of others employed by a selling Holder) shall be borne by the Company.

     1.8 Underwriting Requirements; Cut-backs.

          (a) In connection with any offering involving an underwriting of
     shares of the Company's capital stock, the Company shall not be required to
     include any Holders' Registerable Securities in such underwriting unless
     they accept the terms of the underwriting as agreed upon between the
     Company and the underwriters selected by it (or by other persons entitled
     to select the underwriters), and then only in such quantity as the
     underwriters determine in their sole discretion will not materially
     jeopardize or in any way reduce the success of the offering by the Company.

                                      A-4

<PAGE>   13

          (b) The Company has previously granted "piggyback" registration rights
     to certain of its securityholders (the "Other Holders"). Notwithstanding
     any thing in this Section 1 to the contrary, in the event of any request
     for registration hereunder, the Company shall provide each Other Holder the
     notice required with respect to their registration rights and will allow
     such Other Holders to participate in any such registration to the extent of
     such registration rights; it being acknowledged and agreed that if the
     total amount of securities, including Registerable Securities, requested by
     security holders to be included in such offering exceeds the amount of
     securities that the underwriters determine in their sole discretion is
     compatible with the success of the offering (excluding any securities to be
     offered by the Company), then the Company shall be required to include in
     the offering only that number of such securities, including Registerable
     Securities, which the underwriters determine in their sole discretion will
     not jeopardize the success of the offering (the securities so included to
     be apportioned pro rata among the selling security holders (including
     Holders) according to the total amount of securities entitled to be
     included therein owned by each selling shareholder (including Holders) or
     in such other proportions as shall mutually be agreed to by such selling
     shareholders (including Holders)).

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

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

          (a) To the extent permitted by law, the Company will indemnify and
     hold harmless each Holder, any underwriter (as defined in the Act) for such
     Holder and each person, if any, who controls such Holder or underwriter
     within the meaning of the Act or the 1934 Act against any losses, claims,
     damages, or liabilities, joint or several) to which they may become subject
     under the Act, the 1934 Act or other federal or state law, insofar as such
     losses, claims, damages, or liabilities (or actions in respect thereof)
     arise out of or are based upon any of the following statements, omissions
     or violations (collectively a "Violation"): (i) any untrue statement or
     alleged untrue statement of a material fact contained in such registration
     statement, including any preliminary prospectus or final prospectus
     contained therein or any amendments or supplements thereto, (ii) the
     omission or alleged omission to state therein a material fact required to
     be stated therein, or necessary to make the statements therein not
     misleading, or (iii) any violation or alleged violation by the Company of
     the Act, the 1934 Act, any state securities law or any rule or regulation
     promulgated under the, the 1934 Act or any state securities law; and,
     subject to subsection 1.10 (c) below, the Company will pay to each such
     Holder, underwriter or controlling person, as incurred, any legal or other
     expenses reasonably incurred by them in connection with investigating or
     defending any such loss, claim, damage, liability, or action; provided,
     however, that the indemnity agreement contained in this subsection 1.10(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 reasonably 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 any such Holder, underwriter or controlling person.

                                      A-5
<PAGE>   14

          (b) 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 has signed the registration statement, each person, if any, who
     controls the Company within the meaning of the Act, any underwriter, any
     other Holder selling securities in such registration statement and any
     controlling person of any such underwriter or other Holder, and any agent
     of the Company, against any losses, claims, damages, or liabilities joint
     or several) to which any of the foregoing persons may become subject, under
     the Act, the 1934 Act or other federal or state law, insofar as such
     losses, claims, damages, or liabilities (or actions in respect thereto)
     arise out of or are based upon any Violation, in each case to the extent
     (and only to the extent) that such Violation occurs in reliance upon and in
     conformity with written information furnished by such Holder expressly for
     use in connection with such registration; and each such Holder will pay, as
     incurred, any legal or other expenses reasonably incurred by any person
     intended to be indemnified pursuant to this subsection 1.10(b), in
     connection with investigating or defending any such loss, claim, damage,
     liability, or action; provided, however, that the indemnity agreement
     contained in this subsection 1.10(b) shall not apply to amounts paid in
     settlement of any such loss, claim, damage, liability or action if such
     settlement is effected without the consent of the Holder, which consent
     shall not be reasonably withheld; provided, that, in no event shall any
     indemnity under this subsection 1.10(b) exceed the gross proceeds from the
     offering received by such Holder.

          (c) Promptly after receipt by an indemnified party under this Section
     1.10 of notice of the commencement of any action (including any
     governmental action), such indemnified party will, if a claim in respect
     thereof is to be made against any indemnifying party under this Section
     1.10, deliver to the indemnifying party a written notice of the
     commencement thereof and the indemnifying party shall have the right to
     participate in, and, to the extent the indemnifying party so desires,
     jointly with any other indemnifying party receiving similar notice, to
     assume the defense thereof with counsel reasonably satisfactory to the
     parties; provided, however, that an indemnified party (together with all
     other indemnified party which may be represented without conflict by one
     counsel) shall have the right to retain one separate counsel, with the fees
     and expenses to be paid by the indemnifying party, if representation of
     such indemnified party by the counsel retained by the indemnifying party
     would be inappropriate due to actual or potential differing interests
     between such indemnified party and any other party represented by such
     counsel in such proceeding; otherwise, the indemnified party shall be
     responsible for the fees and expenses of its counsel. The failure to
     deliver written notice to the indemnifying party within a reasonable time
     of the commencement of any such action, if prejudicial to its ability to
     defend such action, shall relieve such indemnifying party of any liability
     to the indemnified party under this Section 1.10.

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

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

          (f) The obligations of the Company and Holders under this Section 1.10
     shall survive the completion of any offering of Registerable Securities
     pursuant to a registration statement under this Section 1.

     1.11 Assignment of Registration Rights. The registration rights of the
Holders under this Section 1 may be assigned (but only with all related
obligations) by a Holder to a transferee or assignee of such securities who

                                      A-6
<PAGE>   15

purchases from such Holder at least 10,000 shares of Registerable Securities
(subject to appropriate adjustment for stock splits, stock dividends,
combinations and other recapitalizations), provided: (a) the Company is promptly
after such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
piggyback registration rights are being assigned; (b) such transferee or
assignee agrees in writing to be bound by and subject to the terms and
conditions of this Agreement, including without limitation the provisions of
Section 1. 12 below; and (c) such assignment shall be effective only if
immediately following such transfer the further disposition of such securities
by the transferee or assignee is restricted under the Act.

     1.12 Lock-up Agreement. Each Holder hereby agrees that if requested by the
Company or the underwriters in any underwritten offering, such Holder shall not,
for the period of 180 days after the effective date of an underwritten public
offering of shares of Common Stock, without the prior written approval of the
Company or such underwriters (as the case may be), directly or indirectly, sell,
offer to sell, contract to sell (including without limitation, any short sale),
grant any option to purchase or otherwise transfer or dispose of any shares of
Common Stock underlying the Warrants legally or beneficially owned by such
Holder; provided, however, in the event of an initial public offering of Common
Stock, no request shall be necessary, with the consent of such Holder to the
above provisions in this Section 1.12 being hereby granted and accepted,
provided that if the managing underwriter in such initial public offering
requests that Holder execute and deliver a lock-up letter, Holder agrees to do
so, which lock-up letter shall be in such managing underwriter's customary form.
In order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registerable Securities of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

     1.13 Termination of Registration Rights. Notwithstanding anything in this
Section 1 to the contrary, no Holder shall be entitled to exercise any right
provided for in this Section 1: (i) at any time more than four (4) years
following the date after the Company becomes a Public Company or (ii) at such
time as such Holder is able to sell all of such Holder's Registerable Securities
in a single three-month period in compliance with Rule 144.

     1.14 Amendments and Waivers. Any term or provision of the registration
rights stated in this Section 1 may be amended and the observance of any term of
such rights may be waived (either generally or in a particular instance and
either retroactively or prospectively), only with the written consent of the
Company and the holders of at a majority of the Registerable Securities then
outstanding. Any amendment or waiver effected in accordance with this Section
1.14 shall be binding upon each holder of any Registerable Securities then
outstanding, each future holder of any Registerable Securities, and the Company.

Stock are sold by the Company at a price less than $6.00 per share, each
Purchaser who purchased shares of Series C Preferred Stock at a price higher
than the lowest issuance price will receive, and the Company agrees to issue,
additional shares of Series C Preferred Stock so that such Purchaser receives
the benefit of such lower issuance price by issuing additional shares of Series
C Preferred Stock in an amount equal to the remainder of (i) the aggregate
amount of such Purchaser's original investment divided by such lower issuance
price minus (ii) the aggregate number of shares of Series C Preferred Stock then
issued to the Purchaser (subject to adjustment for all stock splits, stock
dividends, combinations, recapitalization and the like), and Exhibit A will be
amended accordingly (without any action on the part of the Purchasers). The

                  2.7 LITIGATION. There is no action, suit, proceeding or
investigation pending or, to the best knowledge of the Company, currently
threatened against the Company or any of its subsidiaries that questions the
validity of the Agreements or the right of the Company to enter into them, or to
consummate the transactions contemplated hereby or thereby, or that might
result, either individually or in the aggregate, in any material adverse changes
in the assets, condition or affairs of the Company, financially or otherwise, or
any change in the current equity ownership of the Company, nor is the Company
aware that there is any basis for the foregoing. The foregoing includes, without
limitation, actions pending or to the best knowledge of the Company threatened
in writing involving the prior employment of any of the Company's employees,
their use in connection with the Company's business of any information or
techniques allegedly proprietary to any of their former employers. Neither the
Company nor any of its subsidiaries is a party or subject to the provisions of

SERIES C PREFERRED STOCK PURCHASE AGREEMENT - PAGE 4
<PAGE>   6

licenses, information and other proprietary rights and processes of any other
person or entity other than such licenses or agreements arising from the
purchase of "off the shelf' or standard commercial products. The Company has not
received any communications alleging that the Company has violated or, by
conducting its business, would violate any of the patents, trademarks, service
marks, trade names, copyrights, trade secrets or other proprietary rights or
processes of any other person or entity. The Company, to the best of its
knowledge, is not aware that any of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of such employee's best
efforts to promote the interest of the Company or that would conflict with the
Company's business. To the best knowledge of the Company, neither the execution
or delivery of this Agreement, nor the carrying on of the Company's business by
the employees of the Company, nor the conduct of the Company's business as
proposed, will 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 such employee is now obligated. The Company does not
believe it is or will be necessary to use any inventions of any of its employees
(or persons it currently intends to hire) made prior to their employment by the
Company.

                  2.9 COMPLIANCE WITH OTHER INSTRUMENTS.

                           (a) The Company is not in violation or default of any
provisions of (i) its Certificate of Incorporation or Bylaws (as such documents
are in force and effect as of the Closing Date) or (ii) any instrument,
judgment, order, writ, decree or contract to which it is a party or by which it
is bound, the violation of, or default, which would have a material adverse
effect on the Company, or, to the best knowledge of the Company, of any
provision of federal or state statute, rule or regulation applicable to the
Company. The execution, delivery and performance of the Agreements and the
consummation of the transactions contemplated hereby or thereby will not result
in any such violation or be in conflict with or constitute, with or without the
passage of time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an event which results
in the creation of any lien, charge or encumbrance upon any assets of the
Company.

                           (b) The Company has avoided every condition, and has
not performed any act, the occurrence of which would result in the Company's
loss of any right granted under any license, distribution agreement or other
agreement.

                  2.10 AGREEMENTS; ACTION.

                           (a) There are no agreements, understandings or
proposed transactions between the Company and any of its officers, directors,
affiliates, or any affiliate thereof.

                           (b) Except as created or incurred in the ordinary
course of business, as related to the Company's Universal Connectivity Station,
or for agreements explicitly contemplated

by the Agreements, there are no agreements, understandings, instruments,
contracts or proposed transactions to which the Company or any of its
subsidiaries is a party or by which it is bound that involve (i) obligations
(contingent or otherwise) of, or payments to, the Company or any of its
subsidiaries in excess of, $100,000, (ii) the license of any patent, copyright,
trade secret or other proprietary right to or from the Company or any of its

and relationships) to manufacture, produce, assemble, license, market, or sell
its products to any other person or affect the Company's exclusive right to
develop, manufacture, assemble, distribute, market or sell its products; or (iv)
indemnification by the Company with respect to infringement of proprietary
rights (other than indemnification obligations arising from purchase or sale
agreements entered into in the ordinary course of business).

                           (c) Neither the Company nor any of its subsidiaries
has (i) declared or paid any dividends, or authorized or made any distribution
upon or with respect to any class or series of its capital stock, (ii) incurred
any indebtedness for money borrowed or incurred any other liabilities
individually in excess of $25,000 or in excess of $100,000 in the aggregate,
other than in the ordinary course of business, (iii) made any loans or advances
to any person, other than ordinary advances for travel and relocation expenses
and the like, or (iv) sold, exchanged or otherwise disposed of any of its assets
or rights, other than the sale of its inventory in the ordinary course of
business.

                  2.11 DISCLOSURE. The Company has fully provided the Purchasers
with all the information that the Purchasers have requested for deciding whether
to acquire the Stock and all information that the Company believes is reasonably
necessary to enable the Purchasers to make such a decision, including certain of
the Company's projections describing its proposed business contained in the
Mobility Electronics Company and Business Summary dated March 5, 1999 (the
"Company Summary"). No representation or warranty of the Company contained in
this Agreement and the exhibits attached hereto, any certificate furnished or to
be furnished to Purchasers at the Closing, or the Company Summary (when read
together) contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained herein or
therein not misleading in light of the circumstances under which they were made.
To the extent the Company Summary was prepared by management of the Company, the
Company Summary and the financial and other projections contained in the Company
Summary and other written information provided to the Purchaser were prepared in
good faith (with the exception of information prepared by third party sources
and identified as such in the Company Summary or other written information and
to which the Company makes no representation except that it has no basis to
believe such sections are inaccurate); however, the Company does not warrant
that it will achieve such projections.

                  2.12 NO CONFLICT OF INTEREST. The Company is not indebted,
directly or indirectly, to any of its officers or directors or to their
respective spouses or children, in any amount whatsoever other than in
connection with expenses or advances of expenses incurred in the ordinary course
of business or relocation expenses of employees which amount does not in the
aggregate exceed

$50,000. None of the Company's officers or directors, or any members of their
immediate families, are, directly or indirectly, indebted to the Company (other
than in connection with purchases of the Company's stock) or to the best
knowledge of the Company have any direct or indirect ownership interest in any
firm or corporation with which the Company is affiliated or with which the
Company has a business relationship, or any firm or corporation which competes
with the Company except that officers, directors and/or stockholders of the
Company may own stock in (but not exceeding two percent of the outstanding
capital stock of) any publicly traded company that may compete with the Company.
None of the Company's officers or directors or any members of their immediate
families are, directly or indirectly, interested in any material contract with
the Company. The Company is not a guarantor or indemnitor of any indebtedness of
any other person, firm or corporation.

                  2.13 RIGHTS OF REGISTRATION AND VOTING RIGHTS. Except as

Company has entered into any agreements with respect to the voting of capital
shares of the Company.

                  2.14 TITLE TO PROPERTY AND ASSETS. The Company owns its
property and assets free and clear of all mortgages, liens, loans and
encumbrances, except such encumbrances and liens which arise in the ordinary
course of business and do not materially impair the Company's ownership or use
of such property or assets. With respect to the property and assets it leases,
the Company is in compliance with such leases and, to its knowledge, holds a
valid leasehold interest free of any liens, claims or encumbrances. The Company
is in compliance with all material terms of each material lease to which it is a
party or otherwise bound.

                  2.15 FINANCIAL STATEMENTS. The Company has made available to
each Purchaser the financial statements set forth in the Company Summary
(collectively, the "Financial Statements"). The Financial Statements have been
prepared in accordance with generally accepted accounting principles applied on
a consistent basis throughout the periods indicated, except that the unaudited
Financial Statements may not contain all footnotes required by generally
accepted accounting principles. The Financial Statements fairly present the
financial condition and operating results of the Company as of the dates, and
for the periods, indicated therein, subject to normal year-end audit
adjustments. Except as set forth in the Financial Statements, the Company has no
material liabilities, contingent or otherwise, other than (i) liabilities
incurred in the ordinary course of business subsequent to January 1, 1999 and
(ii) obligations under contracts and commitments incurred in the ordinary course
of business and not required under generally accepted accounting principles to

results of the Company.

respect to its business, properties and operations for such period. The Company
has withheld or collected from each payment made to each of its employees, the

proper tax receiving officers or authorized depositories.

                  2.19 INSURANCE. The Company has in full force and effect fire

any written or oral, express or implied, contract, commitment or arrangement
with any labor union, and no labor union has requested or, to the best knowledge
of the Company, has sought to represent any of the employees, representatives or

Company pending, or to the best knowledge of the Company threatened, which could
have a material adverse effect on the assets, properties, financial condition,
operating results, or business of the Company, nor is the Company aware of any
labor organization activity involving its employees. The Company is not aware
that any officer or key employee, or that any group of key employees, intends to
terminate their employment with the Company, nor does the Company have a present
intention to terminate the employment of any of the foregoing. The employment of
each officer and employee of the Company is terminable at the will of the
Company. The Company has complied in all material respects with all applicable

the business, properties, prospects, or financial condition of the Company. The
Company is not in default in any material respect under any of such franchises,
permits, licenses or other similar authority.

committee of directors) and stockholders with respect to all transactions
referred to in such minutes accurately in all material respects.

Agreement, the offer, sale and issuance of the Securities as contemplated by

Company, the Company's software, hardware and other computer and information
technology (collectively, "Information Technology") is Year 2000 Compliant (as
defined in the next sentence). "Year 2000 Compliant" shall mean that such

time period shall accurately receive, provide and process data/time data
(including, but not limited to. calculation, comparing and sequencing) from,

hereby represents and warrants to the Company that:

                  3.1 AUTHORIZATION. Such Purchaser has full power and authority
to enter into this Agreement. The Agreements, when executed and delivered by the
Purchaser, will constitute valid and legally binding obligations of the
Purchaser, enforceable in accordance with their terms, except (a) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance, and any other laws of general application affecting enforcement of
creditors' rights generally, and as limited by laws relating to the availability
of a specific performance, injunctive relief, or other equitable remedies, or
(b) to the extent the indemnification provisions contained in the Investors'
Rights Agreement may be limited by applicable federal or state securities laws.



SERIES C PREFERRED STOCK PURCHASE AGREEMENT - PAGE 11
<PAGE>   13

                  3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made
with the Purchaser in reliance upon the Purchaser's representation to the
Company, which by the Purchaser's execution of this Agreement the Purchaser
hereby confirms, that the Securities to be acquired by the Purchaser will be
acquired for investment for the Purchaser's own account, not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof,
and that the Purchaser has no present intention of selling, granting any
participation in, or otherwise distributing the same. By executing this
Agreement, the Purchaser further represents that the Purchaser does not
presently have any contract, undertaking, agreement or arrangement with any
person to sell, transfer or grant participation to such person or to any third
person, with respect to any of the Securities. The Purchaser has not been formed
for the specific purpose of acquiring the Securities.

                  3.3 DISCLOSURE OF INFORMATION. The Purchaser has had an
opportunity to discuss the Company's business, management, financial affairs and
the terms and conditions of the offering of the Stock with the Company's
management and has had an opportunity to review the Company's facilities. The
Purchaser understands that such discussions, as well as the Company Summary and
any other written information delivered by the Company to the Purchaser, were
intended to describe the aspects of the Company's business which it believes to
be material.

                  3.4 RESTRICTED SECURITIES. The Purchaser understands that the
Securities have not been, and will not be, registered under the Securities Act,
by reason of a specific exemption from the registration provisions of the
Securities Act which depends upon, among other things, the bona fide nature of
the investment intent and the accuracy of the Purchaser's representations as
expressed herein. The Purchaser understands that the Securities are "restricted
securities" under applicable U.S. federal and state securities laws and that,
pursuant to these laws, the Purchaser must hold the Securities indefinitely
unless they are registered with the Securities and Exchange Commission and
qualified by state authorities, or an exemption from such registration and
qualification requirements is available. The Purchaser acknowledges that the
Company has no obligation to register or qualify the Securities for resale
except as set forth in the Investors' Rights Agreement. The Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Securities,
and on requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

                  3.5 NO PUBLIC MARKET. The Purchaser understands that no public
market now exists for any of the securities issued by the Company, and that the
Company has made no assurances that a public market will ever exist for the
Securities.

                  3.6 LEGENDS. The Purchaser understands that the Securities,
and any securities issued in respect of or exchange for the Securities, may bear
one or all of the following legends (or substantially similar legends):

         THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
AS AMENDED (THE "ACT"), OR ANY APPLICABLE STATE SECURITIES LAW AND MAY NOT BE

                   AMENDED AND RESTATED STOCK PURCHASE WARRANT

         This Amended and Restated Stock Purchase Warrant is issued this 25th
day of March, 1998, by ELECTRONICS ACCESSORY SPECIALISTS INTERNATIONAL, INC., a
Delaware corporation (the "Company"), to SIRROM CAPITAL CORPORATION, a Tennessee
corporation (SIRROM CAPITAL CORPORATION and any subsequent assignee or
transferee hereof are hereinafter referred to collectively as "Holder" or
"Holders"). This Amended and Restated Stock Purchase Warrant amends and restates
that certain Stock Purchase Warrant dated June 24, 1997 issued by the Company to
the Holder (the "Old Warrant") and shall not constitute a novation thereof. Upon
the execution and delivery of this Warrant, Holder shall deliver to the Company
the Old Warrant, marked "Replaced".

                                   AGREEMENT:

         1. ISSUANCE OF WARRANT; TERM. For and in consideration of SIRROM
CAPITAL CORPORATION making a loan to the Company in an amount of One Million Six
Hundred Thousand and no/100ths Dollars ($1,600,000.00) pursuant to the terms of
a secured promissory note dated June 24, 1997 (the "Note") and a related Loan
Agreement dated June 24, 1997 which was amended pursuant to a First Amendment to
Loan Agreement and Loan Documents dated of even date herewith (the "Loan
Agreement"), and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company hereby grants to
Holder the right to purchase 171,698 shares of the Company's common stock (the
"Common Stock"), which the Company represents to equal 1.875% of the capital
stock of the Company on the date hereof, calculated on a fully diluted basis
after exercise ("Base Amount"), provided that in the event that the indebtedness
evidenced by the Note is outstanding on the following dates, the Base Amount
shall be increased to the corresponding number set forth below:

                                  which the Company represents to
                                  equal 2.526% of the capital stock of the
                                  Company on the date hereof calculated

                                  on a fully diluted basis after exercise.
</TABLE>


The shares of Common Stock issuable upon exercise of this Warrant are
hereinafter referred to as the "Shares." This Warrant shall be exercisable at
any time and from time to time from the date hereof until July 31, 2002. For
purposes of this Warrant the term "fully diluted basis" shall be determined in
accordance with generally accepted accounting principles as of the date hereof.

         2. EXERCISE PRICE. The exercise price (the "Exercise Price") per share
for which all or any of the Shares may be purchased pursuant to the terms of
this Warrant shall be One Cent ($.01).

         3. EXERCISE. This Warrant may be exercised by the Holder hereof (but
only on the conditions hereinafter set forth) as to all or any increment or
increments of One Hundred (100) Shares (or the balance of the Shares if less
than such number), upon delivery of written notice of intent to exercise to the
Company at the following address: 7955 East Redfield Road, Scottsdale, Arizona
85260 or such other address as the Company shall designate in a written notice
to the Holder hereof, together with this Warrant and payment to the Company of
the aggregate Exercise Price of the Shares so purchased. The Exercise Price
shall be payable, at the option of the Holder, (i) by certified or bank check,
(ii) by the surrender of the Note or portion thereof having an outstanding
principal balance equal to the aggregate Exercise Price or (iii) by the
surrender of a portion of this Warrant having a fair market value equal to the
aggregate



                                       2
<PAGE>   3

Exercise Price. Upon receipt of the notice of exercise of this Warrant as
aforesaid, the Company shall as promptly as practicable, and in any event within
fifteen (15) days thereafter, execute and deliver to the Holder of this Warrant
a certificate or certificates for the total number of whole Shares for which
this Warrant is being exercised in such names and denominations as are requested
by such Holder. If this Warrant shall be exercised with respect to less than all
of the Shares, the Holder shall be entitled to receive a new Warrant covering
the number of Shares in respect of which this Warrant shall not have been
exercised, which new Warrant shall in all other respects be identical to this
Warrant. The Company covenants and agrees that it will pay when due any and all
state and federal issue taxes which may be payable in respect of the issuance of
this Warrant or the issuance of any Shares upon exercise of this Warrant.

         4. COVENANTS AND CONDITIONS. The above provisions are subject to the
following:

                  (a) Neither this Warrant nor the Shares have been registered
         under the Securities Act of 1933, as amended ("Securities Act") or any
         state securities laws ("Blue Sky Laws"). This Warrant has been acquired
         for investment purposes and not with a view to distribution or resale
         and may not be pledged, hypothecated, sold, made subject to a security
         interest, or otherwise transferred without (i) an effective
         registration statement for such Warrant under the Securities Act and
         such applicable Blue Sky Laws, or (ii) an opinion of counsel, which
         opinion and counsel shall be reasonably satisfactory to the Company and
         its counsel, that registration is not required under the Securities Act
         or under any applicable Blue Sky Laws (the Company hereby acknowledges
         that Bass, Berry & Sims is acceptable counsel). Transfer of the shares
         issued upon the exercise of this Warrant shall be restricted in the
         same manner and to the same extent as the Warrant and the certificates
         representing such Shares shall bear substantially the following legend:

                  THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE
                  HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED (THE "ACT"), OR ANY APPLICABLE STATE SECURITIES LAW
                  AND MAY NOT BE TRANSFERRED UNTIL (I) A REGISTRATION STATEMENT
                  UNDER THE ACT OR SUCH APPLICABLE STATE SECURITIES LAWS SHALL
                  HAVE BECOME EFFECTIVE WITH REGARD THERETO, OR (II) IN THE
                  OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY, REGISTRATION
                  UNDER SUCH SECURITIES ACTS OR SUCH APPLICABLE STATE SECURITIES
                  LAWS IS NOT REQUIRED IN CONNECTION WITH SUCH PROPOSED
                  TRANSFER.


                                       3
<PAGE>   4

The Holder hereof and the Company agree to execute such other documents and
instruments as counsel for the Company reasonably deems necessary to effect the
compliance of the issuance of this Warrant and any shares of Common Stock issued
upon exercise hereof with applicable federal and state securities laws.

                  (b) The Company covenants and agrees that all Shares which may
         be issued upon exercise of this Warrant will, upon issuance and payment
         therefor, be legally and validly issued and outstanding, fully paid and
         nonassessable, free from all taxes, liens, charges and preemptive
         rights, if any, with respect thereto or to the issuance thereof. The
         Company shall at all times reserve and keep available for issuance upon
         the exercise of this Warrant such number of authorized but unissued
         shares of Common Stock as will be sufficient to permit the exercise in
         full of this Warrant.

                  (c) Except for securities issued under the Company's 1996 Long
         Term Incentive Plan, as amended (not to exceed 50% of the common shares
         of Borrower outstanding from time to time on a fully diluted basis,
         with the exercise price per share of any capital stock issued pursuant
         to any option granted under such plan not to be less than 100% of the
         fair market value of such stock on the date such option is granted),
         the Company covenants and agrees that it shall not sell any shares of
         the Company's capital stock at a price below the fair market value of
         such shares (as such may be determined in good faith, from time to
         time, by the Company's board of directors), without the prior written
         consent of the Holder hereof. In the event that the Company sells
         shares of the Company's capital stock in violation of this Section
         4(c), the number of shares of Common Stock issuable upon exercise of
         this Warrant shall be equal to the product obtained by multiplying the
         number of shares then issuable pursuant to this Warrant prior to such
         sale by a fraction, the numerator of which shall be the product of (x)
         the total number of shares of Common Stock outstanding on a fully
         diluted basis immediately after such issuance or sale, multiplied by
         (y) the fair market value immediately prior to such issuance or sale
         and the denominator of which shall be the sum of (i) the number of
         shares of Common Stock outstanding on a fully diluted basis immediately
         prior to such issuance or sale multiplied by the fair market value
         immediately prior to such issuance or sale, plus (ii) the aggregate
         amount of the consideration received by the Company upon such issuance
         or sale (as illustrated on Schedule I hereto).

         5. TRANSFER OF WARRANT. Subject to the provisions of Section 4 hereof,
this Warrant may be transferred, in whole or in part, to any person or business
entity, by presentation of the Warrant to the Company with written instructions
for such transfer. Upon such presentation for transfer, the Company shall



                                       4
<PAGE>   5

promptly execute and deliver a new Warrant or Warrants in the form hereof in the
name of the assignee or assignees and in the denominations specified in such
instructions. The Company shall pay all expenses incurred by it in connection
with the preparation, issuance and delivery of Warrants under this Section.

         6. WARRANT HOLDER NOT SHAREHOLDER; RIGHTS OFFERING; PREEMPTIVE RIGHTS;
PREFERENCE RIGHTS. This Warrant does not confer upon the Holder, as such, any
right whatsoever as a shareholder of the Company. Notwithstanding the foregoing,
if the Company should offer to all of the Company's shareholders the right to
purchase any securities of the Company, then all shares of Common Stock that are
subject to this Warrant shall be deemed to be outstanding and owned by the
Holder and the Holder shall be entitled to participate in such rights offering.
The Company shall not grant any preemptive rights with respect to any of its
capital stock without the prior written consent of the Holder. The Company shall
not issue any securities which entitle the holder thereof to obtain any
preference over holders of Common Stock upon the dissolution, liquidation,
winding-up, sale, merger, or reorganization of the Company without the prior
written consent of the Holder unless: (i) all indebtedness under the Loan
Agreement and/or Note has been paid in full and (ii) the investment made by the
holder thereof is based on the valuation of the Company being at least
$30,000,000.

         7. OBSERVATION RIGHTS. The Holder of this Warrant shall (a) receive
notice of and be entitled to attend or may send a representative to attend all
meetings of the Company's Board of Directors in a non-voting observation
capacity, (b) receive copies of all notices, packages and documents provided to
members of the Company's Board of Directors for each board of directors meeting,
and (c) receive copies of all actions taken by written consent by the Company's
Board of Directors, from the date hereof until such time as the indebtedness
evidenced by the Note has been paid in full.

         8. ADJUSTMENT UPON CHANGES IN STOCK.

                  (a) If all or any portion of this Warrant shall be exercised
         subsequent to any stock split, stock dividend, recapitalization,
         combination of shares of the Company, or other similar event, occurring
         after the date hereof, then the Holder exercising this Warrant shall
         receive, for the aggregate price paid upon such exercise, the aggregate
         number and class of shares which such Holder would have received if
         this Warrant had been exercised immediately prior to such stock split,
         stock dividend, recapitalization, combination of shares, or other
         similar event. If any adjustment under this Section 8(a) would create a
         fractional share of Common Stock or a right to acquire a fractional
         share of Common Stock, such fractional share shall be


                                       5
<PAGE>   6

         disregarded and the number of shares subject to this Warrant shall be
         the next higher number of shares, rounding all fractions upward.
         Whenever there shall be an adjustment pursuant to this Section 8(a),
         the Company shall forthwith notify the Holder or Holders of this
         Warrant of such adjustment, setting forth in reasonable detail the
         event requiring the adjustment and the method by which such adjustment
         was calculated.

                  (b) If all or any portion of this Warrant shall be exercised
         subsequent to any merger, consolidation, exchange of shares,
         separation, reorganization or liquidation of the Company, or other
         similar event, occurring after the date hereof, as a result of which
         shares of Common Stock shall be changed into the same or a different
         number of shares of the same or another class or classes of securities
         of the Company or another entity, then the Holder exercising this
         Warrant shall receive, for the aggregate price paid upon such exercise,
         the aggregate number and class of shares which such Holder would have
         received if this Warrant had been exercised immediately prior to such
         merger, consolidation, exchange of shares, separation, reorganization
         or liquidation, or other similar event. If any adjustment under this
         Section 8(b) would create a fractional share of Common Stock or a right
         to acquire a fractional share of Common Stock, such fractional share
         shall be disregarded and the number of shares subject to this Warrant
         shall be the next higher number of shares, rounding all fractions
         upward. Whenever there shall be an adjustment pursuant to this Section
         8(b), the Company shall forthwith notify the Holder or Holders of this
         Warrant of such adjustment, setting forth in reasonable detail the
         event requiring the adjustment and the method by which such adjustment
         was calculated.

         9. PUT AGREEMENT.

                  (a) The Company hereby irrevocably grants and issues to Holder
         the right and option to sell to the Company (the "Put") this Warrant
         for a period of thirty (30) days immediately prior to the expiration
         thereof, at a purchase price (the "Purchase Price") equal to the Fair
         Market Value (as hereinafter defined) of the shares of Common Stock
         issuable to Holder upon exercise of this Warrant.



                                       6
<PAGE>   7

                  (b) The Company shall pay to the Holder, in cash or certified
         or cashier's check, the Purchase Price in exchange for the delivery to
         the Company of this Warrant within the later of (i) thirty (30) days of
         the receipt of written notice, addressed as set forth in Section 3
         hereto, from the Holder of its intention to exercise the Put, or (ii)
         five (5) days after Fair Market Value is determined by the appraisers
         pursuant to Section 9(c) hereof, not to exceed sixty (60) days of the
         receipt of written notice.

                  (c) The Fair Market Value of the shares of Common Stock of the
         Company issuable pursuant to this Warrant shall be the average trading
         price of shares of Common Stock during the ten (10) trading days
         preceding the date notice of the exercise of the Put is delivered to
         the Company or if the Common Stock is not publicly traded at such time
         shall be determined as follows:

                           (i) The Company and the Holder shall each appoint an
                  independent, experienced appraiser who is a member of a
                  recognized professional association of business appraisers.
                  The two appraisers shall determine the value of the shares of
                  Common Stock which would be issued upon the exercise of the
                  Warrant, taking into consideration that such shares would
                  constitute a minority interest, and would lack liquidity, and
                  further assuming that the sale would be between a willing
                  buyer and a willing seller, both of whom have full knowledge
                  of the financial and other affairs of the Company, and neither
                  of whom is under any compulsion to sell or to buy.

                           (ii) If the highest of the two appraisals is not more
                  than 10% more than the lowest of the appraisals, the Fair
                  Market Value shall be the average of the two appraisals. If
                  the highest of the two appraisals is 10% or more than the
                  lowest of the two appraisals, then a third appraiser shall be
                  appointed by the two appraisers, and if they cannot agree on a
                  third appraiser, within thirty (30) days thereafter, the
                  American Arbitration Association shall appoint the third
                  appraiser. The third appraiser, regardless of who appoints him
                  or her, shall have the same qualifications as the first two
                  appraisers.

                           (iii) The Fair Market Value after the appointment of
                  the third appraiser shall be the mean of the three appraisals.

                           (iv) The fees and expenses of the appraisers shall be
                  paid one-half by the Company and one-half by the Holder.

                  (d) Notwithstanding the foregoing, if the Note has been paid
         in full and either (i) the Company has successfully completed an
         underwritten public offering of the Company's capital stock and the
         Company has a market capitalization in excess of $75,000,000.00, or
         (ii) the Company is purchased by or merged with a public company having
         a market capitalization of at least $75,000,000.00, and the Holder
         receives marketable securities in such public company, the Put shall
         terminate.

         10. REGISTRATION.

                  (a) The Company and the Holder(s) agree that if at any time
         after the date hereof the Company shall propose to file a registration
         statement with respect to any of its Common Stock on a form suitable
         for a secondary offering of shares of Common Stock held by third
         parties and which is not a registration solely to implement an employee
         benefit plan or a transaction to which Rule 145 or any similar rule of
         the Commission (as defined below) is applicable, it will give notice in
         writing to such effect to the registered holder(s) of the Shares at
         least thirty (30) days prior to such filing, and, at the written
         request of any such registered holder, made within ten (10) days after
         the receipt of such notice, will include therein at the Company's cost
         and expense (including the fees and expenses of counsel to such
         holder(s), but excluding underwriting discounts, commissions and filing
         fees attributable to the Shares included therein) such of the Shares as
         such holder(s) shall request; provided, however, that if the offering
         being registered by the Company is underwritten and if the
         representative of the underwriters certifies in writing that the
         inclusion therein of the Shares would materially and adversely affect
         the sale of the securities to be sold by the Company thereunder, then
         the Company shall be required to include in the offering only that
         number of securities of third parties (including Holder(s)), including
         the Shares, which the underwriters determine in their sole discretion
         will not jeopardize the success of the offering (the securities so
         included to be apportioned pro rata among all selling shareholders
         according to the total amount of securities entitled to be included
         therein owned by each selling shareholder.

                  (b) Whenever the Company undertakes to effect the registration
         of any of the Shares, the Company shall, as expeditiously as reasonably
         possible:

                           (i) Prepare and file with the Securities and Exchange
                  Commission (the "Commission") a registration statement
                  covering such Shares and use its best efforts to cause such
                  registration statement to be declared effective by the
                  Commission as expeditiously as possible and to keep such
                  registration effective until


                                       8
<PAGE>   9

                  the earlier of (A) the date when all Shares covered by the
                  registration statement have been sold or (B) one hundred
                  eighty (180) days from the effective date of the registration
                  statement; provided, that before filing a registration
                  statement or prospectus or any amendment or supplements
                  thereto, the Company will furnish to each Holder of Shares
                  covered by such registration statement and the underwriters,
                  if any, copies of all such documents proposed to be filed
                  (excluding exhibits, unless any such person shall specifically
                  request exhibits), which documents will be subject to the
                  review of such Holders and underwriters, and the Company will
                  not file such registration statement or any amendment thereto
                  or any prospectus or any supplement thereto (including any
                  documents incorporated by reference therein) with the
                  Commission if (A) the underwriters, if any, shall reasonably
                  object to such filing or (B) if information in such
                  registration statement or prospectus concerning a particular
                  selling Holder has changed and such Holder or the
                  underwriters, if any, shall reasonably object.

                           (ii) Prepare and file with the Commission such
                  amendments and post-effective amendments to such registration
                  statement as may be necessary to keep such registration
                  statement effective during the period referred to in Section
                  10(b)(i) and to comply with the provisions of the Securities
                  Act with respect to the disposition of all securities covered
                  by such registration statement, and cause the prospectus to be
                  supplemented by any required prospectus supplement, and as so
                  supplemented to be filed with the commission pursuant to Rule
                  424 under the Securities Act.

                           (iii) Furnish to the selling Holder(s) such numbers
                  of copies of such registration statement, each amendment
                  thereto, the prospectus included in such registration
                  statement (including each preliminary prospectus), each
                  supplement thereto and such other documents as they may
                  reasonably request in order to facilitate the disposition of
                  the Shares owned by them.

                           (iv) Use all reasonable efforts to register and
                  qualify under such other securities laws of such jurisdictions
                  as shall be reasonably requested by any selling Holder and do
                  any and all other acts and things which may be reasonably
                  necessary or advisable to enable such selling Holder to
                  consummate the disposition of the Shares owned by such Holder,
                  in such jurisdictions; provided, however, that the Company
                  shall not be required in connection therewith or as a
                  condition thereto to qualify to transact business or to


                                       9
<PAGE>   10

                  file a general consent to service of process in any such
                  states or jurisdictions.

                           (v) Promptly notify each selling Holder of the
                  happening of any event, upon discovery of such event, as a
                  result of which the prospectus included in such registration
                  statement contains an untrue statement of a material fact or
                  omits any fact necessary to make the statements therein not
                  misleading and, at the request of any such Holder, the Company
                  will prepare a supplement or amendment to such prospectus so
                  that, as thereafter delivered to the purchasers of such
                  Shares, such prospectus will not contain an untrue statement
                  of a material fact or omit to state any fact necessary to make
                  the statements therein not misleading.

                           (vi) Provide a transfer agent and registrar for all
                  such Shares not later than the effective date of such
                  registration statement.

                           (vii) Enter into such customary agreements (including
                  underwriting agreements in customary form) and take all such
                  other actions as the underwriters, if any, reasonably request
                  in order to expedite or facilitate the disposition of such
                  Shares (including, without limitation, effecting a stock split
                  or a combination of shares).

                           (viii) Make reasonably available for inspection by
                  any selling Holder or any underwriter participating in any
                  disposition pursuant to such registration statement and any
                  attorney, accountant or other agent retained by any such
                  selling Holder or underwriter, all financial and other
                  records, pertinent corporate documents and properties of the
                  Company, and cause the officers, directors, employees and
                  independent accountants of the Company to supply all
                  information reasonably requested by any such seller,
                  underwriter, attorney, accountant or agent in connection with
                  such registration statement.

                           (ix) Promptly notify the selling Holder(s) and the
                  underwriters, if any, of the following events and (if
                  requested by any such person) confirm such notification in
                  writing: (A) the filing of the prospectus or any prospectus
                  supplement and the registration statement and any amendment or
                  post-effective amendment thereto and, with respect to the
                  registration statement or any post-effective amendment
                  thereto, the declaration of the effectiveness of such
                  documents, (B) any requests by the Commission for amendments
                  or supplements to the registration statement or the prospectus
                  or for additional information, (C) the issuance or threat of


                                       10
<PAGE>   11

                  effectiveness of the registration statement or the initiation
                  of any proceedings for that purpose, and (D) the receipt by
                  the Company of any notification with respect to the suspension
                  of the qualification of the Shares for sale in any
                  jurisdiction or the initiation or threat of initiation of any
                  proceeding for such purposes.

                           (x) Make every reasonable effort to prevent the entry
                  of any order suspending the effectiveness of the registration
                  statement and obtain at the earliest possible moment the
                  withdrawal of any such order, if entered.

                           (xi) Cooperate with the selling Holder(s) and the
                  underwriters, if any, to facilitate the timely preparation and
                  delivery of certificates representing the Shares to be sold
                  and not bearing any restrictive legends, and enable such
                  Shares to be in such lots and registered in such names as the
                  underwriters may request at least two (2) business days prior
                  to any delivery of the Shares to the underwriters.

                           (xii) Provide a CUSIP number for all the Shares not
                  later than the effective date of the registration statement.

                           (xiii) Prior to the effectiveness of the registration
                  statement and any post-effective amendment thereto and at
                  each closing of an underwritten offering, (A) make such
                  representations and warranties to the selling Holder(s) and
                  the underwriters, if any, with respect to the Shares and the
                  registration statement as are customarily made by issuers in
                  primary underwritten offerings; (B) use its best efforts to
                  obtain "cold comfort" letters and updates thereof from the
                  Company's independent certified public accountants addressed
                  to the selling Holders and the underwriters, if any, such
                  letters to be in customary form and covering matters of the
                  type customarily covered in "cold comfort" letters by
                  underwriters in connection with underwritten offerings; (C)
                  deliver such-documents and certificates as may be reasonably
                  requested (1) by the holders of a majority of the Shares being
                  sold, and (2) by the underwriters, if any, to evidence
                  compliance with clause (A) above and with any customary
                  conditions contained in the underwriting agreement or other
                  agreement entered into by the Company; and (D) obtain opinions
                  of counsel to the Company and updates thereof (which counsel
                  and which opinions shall be reasonably satisfactory to the
                  underwriters, if any), covering the matters customarily
                  covered in opinions requested in


                                       11
<PAGE>   12

                  underwritten offerings and such other matters as may be
                  reasonably requested by the selling Holders and underwriters
                  or their counsel. Such counsel shall also state that no facts
                  have come to the attention of such counsel which cause them to
                  believe that such registration statement, the prospectus
                  contained therein, or any amendment or supplement thereto, as
                  of their respective effective or issue dates, contains any
                  untrue statement of any material fact or omits to state any
                  material fact necessary to make the statements therein not
                  misleading (except that no statement need be made with respect
                  to any financial statements, notes thereto or other financial
                  data or other expertized material contained therein). If for
                  any reason the Company's counsel is unable to give such
                  opinion, the Company shall so notify the Holders of the Shares
                  and shall use its best efforts to remove expeditiously all
                  impediments to the rendering of such opinion.

                           (xiv) Otherwise use its best efforts to comply with
                  all applicable rules and regulations of the Commission and
                  make generally available to its security holders earnings
                  statements satisfying the provisions of Section 11(a) of the
                  Securities Act, no later than forty-five (45) days after the
                  end of any twelve-month period (or ninety (90) days, if such
                  period is a fiscal year) (A) commencing at the end of any
                  fiscal quarter in which the Shares are sold to underwriters in
                  a firm or best efforts underwritten offering, or (B) if not
                  sold to underwriters in such an offering, beginning with the
                  first month of the first fiscal quarter of the Company
                  commencing after the effective date of the registration
                  statement, which statements shall cover such twelve-month
                  periods.

                  (c) After the date hereof, the Company shall not grant to any
         holder of securities of the Company any registration rights which have
         a priority greater than or equal to those granted to Holders pursuant
         to this Warrant without the prior written consent of the Holder(s).

                  (d) The Company's obligations under Section 10(a) above with
         respect to each holder of Shares are expressly conditioned upon such
         holder's furnishing to the Company in writing such information
         concerning such holder and the terms of such holder's proposed offering
         as the Company shall reasonably request for inclusion in the
         registration statement. If any registration statement including any of
         the Shares is filed, then the Company shall indemnify each holder
         thereof (and each underwriter for such holder and each person, if any,
         who controls such underwriter within the meaning of the Securities Act)
         from any loss, claim, damage or liability arising out of, based upon or
         in any way


                                       12
<PAGE>   13

         relating to any untrue statement of a material fact contained in such
         registration statement or any omission to state therein a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, except for any such statement or omission based
         on information furnished in writing by such holder of the Shares for
         use in connection with such registration statement; and such holder
         shall indemnify the Company (and each of its officers and directors who
         has signed such registration statement, each director, each person, if
         any, who controls the Company within the meaning of the Securities Act,
         each underwriter for the Company and each person, if any, who controls
         such underwriter within the meaning of the Securities Act) and each
         other such holder against any loss, claim, damage or liability arising
         from any such statement or omission which was made in reliance upon
         information furnished in writing to the Company by such holder of the
         Shares for use in connection with such registration statement.

                  (e) For purposes of this Section 10, all of the Shares shall
         be deemed to be issued and outstanding.

         11. CERTAIN NOTICES. In case at any time the Company shall propose to:

                  (a) declare any cash dividend upon its Common Stock;

                  (b) declare any dividend upon its Common Stock payable in
         stock or make any special dividend or other distribution to the holders
         of its Common Stock;

                  (c) offer for subscription to the holders of any of its Common
         Stock any additional shares of stock in any class or other rights;

                  (d) reorganize, or reclassify the capital stock of the
         Company, or consolidate, merge or otherwise combine with (except where
         the company is the surviving entity), or sell all or substantially all
         of its assets to, another corporation; or

         to vote in respect of any such reorganization, reclassification,
         consolidation, merger, sale, dissolution,

         liquidation or winding up, and (ii) in the case of such reorganization,
         reclassification, consolidation, merger, sale, dissolution, liquidation
         or winding up, at least twenty (20) days' prior written notice of the
         date when the same shall take place. Any notice required by clause (i)
         shall also specify, in the case of any such dividend, distribution or
         subscription rights, the date on which the holders of Common Stock
         shall be entitled thereto, and any notice required by clause (ii) shall
         specify the date on which the holders of Common Stock shall be entitled
         to exchange their Common Stock for securities or other property
         deliverable upon such reorganization, reclassification, consolidation,
         merger, sale, dissolution, liquidation or winding up, as the case may
         be.

         12. RIGHTS OF CO-SALE.

                  (a) Co-Sale Right. Until such time as the Company does an
         underwritten public offering raising at least $10,000,000.00, neither
         Empire National II, LLC, Charles R. Mollo, Jeffrey S. Doss, Cameron
         Wilson, nor Janice L. Breeze (individually a "Selling Shareholder" and
         collectively the "Selling Shareholders") shall enter into any
         transaction that would result in the sale by it of any Common Stock now
         or hereafter owned by it, unless prior to such sale the Selling
         Shareholder shall give notice to Holder of its intention to effect such
         sale in order that Holder may exercise its rights under this Section 12
         as hereinafter described. Such notice shall set forth (i) the number of
         shares to be sold by the Selling Shareholder, (ii) the principal terms
         of the sale, including the price at which the shares are intended to be
         sold, and (iii) an offer by the Selling Shareholder to use its best
         efforts to cause to be included with the shares to be sold by it in the
         sale, on a share-by-share basis and on the same terms and conditions,
         the Shares issuable or issued to Holder pursuant this Warrant.

                  (b) Rejection of Co-Sale Offer. If Holder has not accepted
         such offer in writing within a period of ten (10) days from the date of
         receipt of the notice, then the Selling Shareholder shall thereafter be
         free for a period of ninety (90) days to sell the number of shares
         specified in such notice, at a price no greater than the price set
         forth in such notice and on otherwise no more favorable terms to the
         Selling Shareholder than as set forth in such notice, without any
         further obligation to Holder in connection with such sale. In the event
         that the Selling Shareholder fails to consummate such sale within such
         ninety-day period, the shares specified in such notice shall continue
         to be subject to this Section.


                                       14
<PAGE>   15

                  (c) Acceptance of Co-Sale Offer. If Holder accepts such offer
         in writing within ten (10) day period, such acceptance shall be
         irrevocable unless the Selling Shareholder shall be unable to cause to
         be included in his sale the number of Shares of stock held by Holder
         and set forth in the written acceptance. In that event, the Selling
         Shareholder and Holder shall participate in the sale pro rata based on
         their ownership.

                  (d) Offers Not Covered. The restrictions under this Section 12
         will not apply to any sale or transfer of any Common Stock by a Selling
         Shareholder to immediate family members (parent, grandparent, spouse,
         children, grandchildren and siblings), or trusts for the benefit of
         such family members of such Selling Shareholder, or the estate of a
         Selling Shareholder as long as such transferee acknowledges that such
         Common Stock shall remain subject to the terms of this Section 12, as
         if held by a Selling Shareholder, and such transferee executes an
         agreement stating that it is bound by the terms of this Section 12 and
         will hold such shares of Common Stock subject to all such terms and
         conditions.

         13. EQUITY PARTICIPATION. This Warrant is issued in connection with the
Loan Agreement. It is intended that this Warrant constitute an equity
participation under and pursuant to T.C.A. Section.47-24-101, et seq. and that
such equity participation be permitted under said statutes and not constitute
interest on the Note. If under any circumstances whatsoever, fulfillment of any
obligation of this Warrant, the Loan Agreement, or any other agreement or
document executed in connection with the Loan Agreement, shall violate the
lawful limit of any applicable usury statute or any other applicable law with
regard to obligations of like character and amount, then the obligation to be
fulfilled shall be reduced to such lawful limit, such that in no event shall
there occur, under this Warrant, the Loan Agreement, or any other document or
instrument executed in connection with the Loan Agreement, any violation of such
lawful limit, but such obligation shall be fulfilled to the lawful limit. If any
sum is collected in excess of the lawful limit, such excess shall be applied to
reduce the principal amount of the Note.

         14. GOVERNING LAW. This warrant shall be governed by the laws of the
State of Tennessee applicable to agreements made entirely within the State.

         15. SEVERABILITY. If any provision(s) of this Warrant or the
application thereof to any person or circumstances shall be invalid or
unenforceable to any extent, the remainder of this Warrant and the application
of such provisions to other


                                       15
<PAGE>   16

persons or circumstances shall not be affected thereby and shall be enforced to
the greatest extent permitted by law.

         16. COUNTERPARTS. This Warrant may be executed in any number of
counterparts and be different parties to this Warrant in separate counterparts,
each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same Warrant.

         17. JURISDICTION AND VENUE. The Company hereby consents to the
jurisdiction of the courts of the State of Tennessee and the United States
District Court for the Middle District of Tennessee, as well as to the
jurisdiction of all courts from which an appeal may be taken from such courts,
for the purpose of any suit, action or other proceeding arising out of any of
its obligations arising under this Agreement or with respect to the transactions
contemplated hereby, and expressly waives any and all objections it may have as
to venue in any such courts.

     2. EXERCISE PRICE. The exercise price (the "Exercise Price") per share for
which all or any of the Shares may be purchased pursuant to the terms of this
Warrant shall be One Cent ($.01).

     3. EXERCISE. This warrant may be exercised by the Holder hereof (but only
on the conditions hereinafter set forth) as to all or any increment or
increments of one Hundred (100) Shares (or the balance of the Shares if less
than such number), upon delivery of written notice of intent to exercise to the
Company at the following address: 7955 East Redfield Road, Scottsdale, Arizona
85260 or such other address as the Company shall designate in a written notice
to the Holder hereof, together with this Warrant and payment to the Company of
the aggregate Exercise


                                       2

<PAGE>   3

Price of the Shares so purchased. The Exercise Price shall be payable, at the
option of the Holder, (i) by certified or bank check, (ii) by the surrender of
the Note or portion thereof having an outstanding principal balance equal to the
aggregate Exercise Price or (iii) by the surrender of a portion of this Warrant
having a fair market value equal to the aggregate Exercise Price. Upon receipt
of the notice of exercise of this Warrant as aforesaid, the Company shall as
promptly as practicable, and in any event within fifteen (15) days thereafter,
execute and deliver to the Holder of this Warrant a certificate or certificates
for the total number of whole Shares for which this Warrant is being exercised
in such names and denominations as are requested by such Holder. If this Warrant
shall be exercised with respect to less than all of the Shares, the Holder shall
be entitled to receive a new Warrant covering the number of Shares in respect of
which this Warrant shall not have been exercised, which new Warrant shall in all
other respects be identical to this Warrant. The Company covenants and agrees
that it will pay when due any and all state and federal issue taxes which may be
payable in respect of the issuance of this Warrant or the issuance of any Shares
upon exercise of this Warrant.

     4. COVENANTS AND CONDITIONS. The above provisions are subject to the
following:

          (a) Neither this Warrant nor the Shares have been registered under the
     Securities Act of 1933, as amended ("Securities Act") or any state
     securities laws ("Blue Sky Laws"). This Warrant has been acquired for
     investment purposes and not with a view to distribution or resale and may
     not be pledged, hypothecated, sold, made subject to a security interest, or
     otherwise transferred without (i) an effective registration statement for
     such Warrant under the Securities Act and such applicable Blue Sky Laws, or
     (ii) an opinion of counsel, which opinion and counsel shall be reasonably
     satisfactory to the Company and its counsel, that registration is not
     required under the Securities Act or under any applicable Blue Sky Laws
     (the Company hereby acknowledges that Bass, Berry & Sims is acceptable
     counsel). Transfer of the shares issued upon the exercise of this Warrant
     shall be restricted in the same manner and to the same extent as the
     Warrant and the certificates representing such Shares shall bear
     substantially the following legend:

          THE SHARES OF COMMON STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT
          BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "ACT"), OR ANY APPLICABLE STATE SECURITIES LAW AND MAY NOT BE
          TRANSFERRED UNTIL (I) A REGISTRATION STATEMENT UNDER THE ACT OR SUCH
          APPLICABLE STATE SECURITIES LAWS SHALL HAVE BECOME EFFECTIVE WITH
          REGARD

                                       3

<PAGE>   4

          THERETO, OR (II) IN THE OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY,
          REGISTRATION UNDER SUCH SECURITIES ACTS OR SUCH APPLICABLE STATE
          SECURITIES LAWS IS NOT REQUIRED IN CONNECTION WITH SUCH PROPOSED
          TRANSFER.

The Holder hereof and the Company agree to execute such other documents and
instruments as counsel for the Company reasonably deems necessary to effect the
compliance of the issuance of this Warrant and any shares of Common Stock issued
upon exercise hereof with applicable federal and state securities laws.

          (b) The Company covenants and agrees that all Shares which may be
     issued upon exercise of this Warrant will, upon issuance and payment
     therefor, be legally and validly issued and outstanding, fully paid and
     nonassessable, free from all taxes, liens, charges and preemptive rights,
     if any, with respect thereto or to the issuance thereof. The Company shall
     at all times reserve and keep available for issuance upon the exercise of
     this Warrant such number of authorized but unissued shares of Common Stock
     as will be sufficient to permit the exercise in full of this Warrant.

          (c) Except for securities issued under the Company's 1996 Long Term
     Incentive Plan, as amended, (not to exceed 10% of the common shares of
     Borrower outstanding from time-to-time on a fully diluted basis, with the
     exercise price per share of any capital stock issued pursuant to any option
     granted under such plan not to be less than 100% of the fair market value
     of such stock on the date such option is granted), the Company covenants
     and agrees that it shall not sell any shares of the Company's capital stock
     at a price below the fair market value of such shares (as such may be
     determined in good faith, from time to time, by the Company's board of
     directors), without the prior written consent of the Holder hereof. In the
     event that the Company sells shares of the Company's capital stock in
     violation of this Section 4(c), the number of shares of Common Stock
     issuable upon exercise of this Warrant shall be equal to the product
     obtained by multiplying the number of shares then issuable pursuant to this
     Warrant prior to such sale by a fraction, the numerator of which shall be
     the product of (x) the total number of shares of Common Stock outstanding
     on a fully diluted basis immediately after such issuance or sale,
     multiplied by (y) the fair market value immediately prior to such issuance
     or sale and the denominator of which shall be the sum of (i) the number of
     shares of Common Stock outstanding on a fully diluted basis immediately
     prior to such issuance or sale multiplied by the fair market value
     immediately prior to such issuance or sale, plus (ii) the aggregate amount
     of the consideration received by the Company upon such issuance or sale (as
     illustrated on Schedule I hereto).

     5. TRANSFER OF WARRANT. Subject to the provisions of Section 4 hereof, this
Warrant may be transferred, in whole or in part, to any person or business
entity, by presentation of the Warrant to the Company with written instructions
for such transfer. Upon such presentation for transfer, the Company shall
promptly execute and deliver a new Warrant or Warrants in the form hereof in the
name of the assignee or assignees and in the denominations specified in such
instructions. The Company shall pay all expenses incurred by it in connection
with the preparation, issuance and delivery of Warrants under this Section.

     6. WARRANT HOLDER NOT SHAREHOLDER; RIGHTS OFFERING; PREEMPTIVE RIGHTS;
PREFERENCE RIGHTS. This Warrant does not confer upon the Holder, as such, any
right whatsoever as a shareholder of the Company. Notwithstanding the foregoing,
if the Company should offer to all of the Company's shareholders the right to
purchase any securities of the Company, then all shares of Common Stock that are
subject to this Warrant shall be deemed to be outstanding and owned by the
Holder and the Holder shall be entitled to participate in such rights offering.
The Company shall not grant any preemptive rights with respect to any of its
capital stock without the prior written consent of the Holder. The Company shall
not issue any securities which entitle the holder thereof to obtain any
preference over holders of Common Stock upon the dissolution, liquidation,
winding-up, sale, merger, or reorganization of the Company without the prior
written consent of the Holder unless: (i) all indebtedness under the Loan
Agreement and/or Note has been paid in full and (ii) the investment made by the
holder thereof is based on the valuation of the Company being at least
$30,000,000.

     7. OBSERVATION RIGHTS. The Holder of this Warrant shall (a) receive notice
of and be entitled to attend or may send a representative to attend all meetings
of the Company's Board of Directors in a non-voting observation capacity, (b)
receive copies of all notices, packages and documents provided to members of the
Company's Board of Directors for each board of directors meeting, and (c)
receive copies of all actions taken by written consent by the Company's Board of
Directors, from the date hereof until such time as the indebtedness evidenced by
the Note has been paid in full.

     8. ADJUSTMENT UPON CHANGES IN STOCK.

          (a) If all or any portion of this Warrant shall be exercised
     subsequent to any stock split, stock dividend, recapitalization,
     combination of shares of the Company, or other similar event, occurring
     after the date hereof, then the Holder exercising this Warrant shall
     receive, for the aggregate price paid upon such exercise, the aggregate
     number and class of shares which such Holder would have received if this
     Warrant had been exercised immediately


                                       5

<PAGE>   6

     prior to such stock split, stock dividend, recapitalization, combination of
     shares, or other similar event. If any adjustment under this Section 8(a)
     would create a fractional share of Common Stock or a right to acquire a
     fractional share of Common Stock, such fractional share shall be
     disregarded and the number of shares subject to this Warrant shall be the
     next higher number of shares, rounding all fractions upward. Whenever there
     shall be an adjustment pursuant to this Section 8(a), the Company shall
     forthwith notify the Holder or Holders of this Warrant of such adjustment,
     setting forth in reasonable detail the event requiring the adjustment and
     the method by which such adjustment was calculated.

          (b) If all or any portion of this Warrant shall be exercised
     subsequent to any merger, consolidation, exchange of shares, separation,
     reorganization or liquidation of the Company, or other similar event,
     occurring after the date hereof, as a result of which shares of Common
     Stock shall be changed into the same or a different number of shares of the
     same or another class or classes of securities of the Company or another
     entity, then the Holder exercising this Warrant shall receive, for the
     aggregate price paid upon such exercise, the aggregate number and class of
     shares which such Holder would have received if this Warrant had been
     exercised immediately prior to such merger, consolidation, exchange of
     shares, separation, reorganization or liquidation, or other similar event.
     If any adjustment under this Section 8(b) would create a fractional share
     of Common Stock or a right to acquire a fractional share of Common Stock,
     such fractional share shall be disregarded and the number of shares subject
     to this Warrant shall be the next higher number of shares, rounding all
     fractions upward. Whenever there shall be an adjustment pursuant to this
     Section 8(b), the Company shall forthwith notify the Holder or Holders of
     this Warrant of such adjustment, setting forth in reasonable detail the
     event requiring the adjustment and the method by which such adjustment was
     calculated.

     9.   PUT AGREEMENT.

          (a) The Company hereby irrevocably grants and issues to Holder the
     right and option to sell to the Company (the "Put") this Warrant for a
     period of thirty (30) days immediately prior to the expiration thereof, at
     a purchase price (the "Purchase Price") equal to the Fair Market Value (as
     hereinafter defined) of the shares of Common Stock issuable to Holder upon
     exercise of this Warrant.


                                       6

<PAGE>   7

          (b) The Company shall pay to the Holder, in cash or certified or
     cashier's check, the Purchase Price in exchange for the delivery to the
     Company of this Warrant within the later of (i) thirty (30) days of the
     receipt of written notice, addressed as set forth in Section 3 hereto, from
     the Holder of its intention to exercise the Put, or (ii) five (5) days
     after Fair Market Value is determined by the appraisers pursuant to Section
     9(c) hereof, not to exceed sixty (60) days of the receipt of written
     notice.

          (c) The Fair Market Value of the shares of Common Stock of the Company
     issuable pursuant to this Warrant shall be the average trading price of
     shares of Common Stock during the ten (10) trading days preceding the date
     notice of the exercise of the Put is delivered to the Company or if the
     Common Stock is not publicly traded at such time shall be determined as
     follows:

               (i) The Company and the Holder shall each appoint an independent,
          experienced appraiser who is a member of a recognized professional
          association of business appraisers. The two appraisers shall determine
          the value of the shares of Common Stock which would be issued upon the
          exercise of the Warrant, taking into consideration that such shares
          would constitute a minority interest, and would lack liquidity, and
          further assuming that the sale would be between a willing buyer and a
          willing seller, both of whom have full knowledge of the financial and
          other affairs of the Company, and neither of whom is under any
          compulsion to sell or to buy.

               (ii) If the highest of the two appraisals is not more than 10%
          more than the lowest of the appraisals, the Fair Market Value shall be
          the average of the two appraisals. If the highest of the two
          appraisals is 10% or more than the lowest of the two appraisals, then
          a third appraiser shall be appointed by the two appraisers, and if
          they cannot agree on a third appraiser, within thirty (30) days
          thereafter, the American Arbitration Association shall appoint the
          third appraiser. The third appraiser, regardless of who appoints him
          or her, shall have the same qualifications as the first two
          appraisers.

               (iii) The Fair Market Value after the appointment of the third
          appraiser shall be the mean of the three appraisals.

               (iv) The fees and expenses of the appraisers shall be paid
          one-half by the Company and one-half by the Holder.


                                       7


<PAGE>   8

               (d) Notwithstanding the foregoing, if the Note has been paid in
          full and either (i) the Company has successfully completed an
          underwritten public offering of the Company's capital stock and the
          Company has a market capitalization in excess of $75,000,000.00, or
          (ii) the Company is purchased by or merged with a public company
          having a market capitalization of at least $75,000,000.00, and the
          Holder receives marketable securities in such public company, the Put
          shall terminate.

          10.  REGISTRATION.

               (a) The Company and the Holder(s) agree that if at any time after
          the date hereof the Company shall propose to file a registration
          statement with respect to any of its Common Stock on a form suitable
          for a secondary offering of shares of Common Stock held by third
          parties and which is not a registration solely to implement an
          employee benefit plan or a transaction to which Rule 145 or any
          similar rule of the Commission (as defined below) is applicable, it
          will give notice in writing to such effect to the registered holder(s)
          of the Shares at least thirty (30) days prior to such filing, and, at
          the written request of any such registered holder, made within ten
          (10) days after the receipt of such notice, will include therein at
          the Company's cost and expense (including the fees and expenses of
          counsel to such holder(s), but excluding underwriting discounts,
          commissions and filing fees attributable to the Shares included
          therein) such of the Shares as such holder(s) shall request; provided,
          however, that if the offering being registered by the Company is
          underwritten and if the representative of the underwriters certifies
          in writing that the inclusion therein of the Shares would materially
          and adversely affect the sale of the securities to be sold by the
          Company thereunder, then the Company shall be required to include in
          the offering only that number of securities of third parties
          (including Holder(s)), including the Shares, which the underwriters
          determine in their sole discretion will not jeopardize the success of
          the offering (the securities so included to be apportioned pro rata
          among all selling shareholders according to the total amount of
          securities entitled to be included therein owned by each selling
          shareholder.

               (b) Whenever the Company undertakes to effect the registration of
          any of the Shares, the Company shall, as expeditiously as reasonably
          possible:

                    (i) Prepare and file with the Securities and Exchange
               Commission (the "Commission") a registration statement covering
               such Shares and use its best efforts to cause such registration
               statement to be declared effective by the Commission as
               expeditiously as possible and to keep such registration effective
               until


                                       8

<PAGE>   9

               the earlier of (A) the date when all Shares covered by the
               registration statement have been gold or (B) one hundred eighty
               (180) days from the effective date of the registration statement;
               provided, that before filing a registration statement or
               prospectus or any amendment or supplements thereto, the Company
               will furnish to each Holder of Shares covered by such
               registration statement and the underwriters, if any, copies of
               all such documents proposed to be filed (excluding exhibits,
               unless any such person shall specifically request exhibits),
               which documents will be subject to the review of such Holders and
               underwriters, and the Company will not file such registration
               statement or any amendment thereto or any prospectus or any
               supplement thereto (including any documents incorporated by
               reference therein) with the Commission if (A) the underwriters,
               if any, shall reasonably object to such filing or (B) if
               information in such registration statement or prospectus
               concerning a particular selling Holder has changed and such
               Holder or the underwriters, if any, shall reasonably object.

                    (ii) Prepare and file with the Commission such amendments
               and post-effective amendments to such registration statement as
               may be necessary to keep such registration statement effective
               during the period referred to in Section 10(b)(i) and to comply
               with the provisions of the Securities Act with respect to the
               disposition of all securities covered by such registration
               statement, and cause the prospectus to be supplemented by any
               required prospectus supplement, and as so supplemented to be
               filed with the commission pursuant to Rule 424 under the
               Securities Act.

                    (iii) Furnish to the selling Holder(s) such numbers of
               copies of such registration statement, each amendment thereto,
               the prospectus included in such registration statement (including
               each preliminary prospectus), each supplement thereto and such
               other documents as they may reasonably request in order to
               facilitate the disposition of the Shares owned by them.

                    (iv) Use all reasonable efforts to register and qualify
               under such other securities laws of such jurisdictions as shall
               be reasonably requested by any selling Holder and do any and all
               other acts and things which may be reasonably necessary or
               advisable to enable such selling Holder to consummate the
               disposition of the Shares owned by such Holder, in such
               jurisdictions; provided, however, that the Company shall not be
               required in connection therewith or as a condition thereto to
               qualify to transact business or to


                                       9

<PAGE>   10

               file a general consent to service of process in any such states
               or jurisdictions.

                    (v) Promptly notify each selling Holder of the happening of
               any event, upon discovery of such event, as a result of which the
               prospectus included in such registration statement contains an
               untrue statement of a material fact or omits any fact necessary
               to make the statements therein not misleading and, at the request
               of any such Holder, the Company will prepare a supplement or
               amendment to such prospectus so that, as thereafter delivered to
               the purchasers of such Shares, such prospectus will not contain
               an untrue statement of a material fact or omit to state any fact
               necessary to make the statements therein not misleading.

                    (vi) Provide a transfer agent and registrar for all such
               Shares not later than the effective date of such registration
               statement.

                    (vii) Enter into such customary agreements (including
               underwriting agreements in customary form) and take all such
               other actions as the underwriters, if any, reasonably request in
               order to expedite or facilitate the disposition of such Shares
               (including, without limitation, effecting a stock split or a
               combination of shares).

                    (viii) Make reasonably available for inspection by any
               selling Holder or any underwriter participating in any
               disposition pursuant to such registration statement and any
               attorney, accountant or other agent retained by any such selling
               Holder or underwriter, all financial and other records, pertinent
               corporate documents and properties of the Company, and cause the
               officers, directors, employees and independent accountants of the
               Company to supply all information reasonably requested by any
               such seller, underwriter, attorney, accountant or agent in
               connection with such registration statement.

                    (ix) Promptly notify the selling Holder(s) and the
               underwriters, if any, of the following events and (if requested
               by any such person) confirm such notification in writing: (A) the
               filing of the prospectus or any prospectus supplement and the
               registration statement and any amendment or post-effective
               amendment thereto and, with respect to the registration statement
               or any post-effective amendment thereto, the declaration of the
               effectiveness of such documents, (B) any requests by the
               Commission for amendments or supplements to the registration
               statement or the prospectus or for additional information, (C)
               the issuance or threat of


                                       10

<PAGE>   11

               issuance by the Commission of any stop order suspending the
               effectiveness of the registration statement or the initiation of
               any proceedings for that purpose, and (D) the receipt by the
               Company of any notification with respect to the suspension of the
               qualification of the Shares for sale in any jurisdiction or the
               initiation or threat of initiation of any proceeding for such
               purposes.

                    (x) Make every reasonable effort to prevent the entry of any
               order suspending the effectiveness of the registration statement
               and obtain at the earliest possible moment the withdrawal of any
               such order, if entered.

                    (xi) Cooperate with the selling Holder(s) and the
               underwriters, if any, to facilitate the timely preparation and
               delivery of certificates representing the Shares to be sold and
               not bearing any restrictive legends, and enable such Shares to be
               in such lots and registered in such names as the underwriters may
               request at least two (2) business days prior to any delivery of
               the Shares to the underwriters.

                    (xii) Provide a CUSIP number for all the Shares not later
               than the effective date of the registration statement.

                    (xiii) Prior to the effectiveness of the registration
               statement and any post-effective amendment thereto and at each
               closing of an underwritten offering, (A) make such
               representations and warranties to the selling Holder(s) and the
               underwriters, if any, with respect to the Shares and the
               registration statement as are customarily made by issuers in
               primary underwritten offerings; (B) use its best efforts to
               obtain "cold comfort" letters and updates thereof from the
               Company's independent certified public accountants addressed to
               the selling Holders and the underwriters, if any, such letters to
               be in customary form and covering matters of the type customarily
               covered in "cold comfort" letters by underwriters in connection
               with underwritten offerings; (C) deliver such-documents and
               certificates as may be reasonably requested (1) by the holders of
               a majority of the Shares being sold, and (2) by the underwriters,
               if any, to evidence compliance with clause (A) above and with any
               customary conditions contained in the underwriting agreement or
               other agreement entered into by the Company; and (D) obtain
               opinions of counsel to the Company and updates thereof (which
               counsel and which opinions shall be reasonably satisfactory to
               the underwriters, if any), covering the matters customarily
               covered in opinions requested in



                                       11

<PAGE>   12

               underwritten offerings and such other matters as may be
               reasonably requested by the selling Holders and underwriters or
               their counsel. Such counsel shall also state that no facts have
               come to the attention of such counsel which cause them to believe
               that such registration statement, the prospectus contained
               therein, or any amendment or supplement thereto, as of their
               respective effective or issue dates, contains any untrue
               statement of any material fact or omits to state any material
               fact necessary to make the statements therein not misleading
               (except that no statement need be made with respect to any
               financial statements, notes thereto or other financial data or
               other expertized material contained therein). If for any reason
               the Company's counsel is unable to give such opinion, the Company
               shall so notify the Holders of the Shares and shall use its best
               efforts to remove expeditiously all impediments to the rendering
               of such opinion.

                    (xiv) Otherwise use its best efforts to comply with all
               applicable rules and regulations of the Commission and make
               generally available to its security holders earnings statements
               satisfying the provisions of Section 11(a) of the Securities Act,
               no later than forty-five (45) days after the end of any
               twelve-month period (or ninety (90) days, if such period is a
               fiscal year) (A) commencing at the end of any fiscal quarter in
               which the Shares are sold to underwriters in a firm or best
               efforts underwritten offering, or (B) if not sold to underwriters
               in such an offering, beginning with the first month of the first
               fiscal quarter of the Company commencing after the effective date
               of the registration statement, which statements shall cover such
               twelve-month periods.

               (c) After the date hereof, the Company shall not grant to any
          holder of securities of the Company any registration rights which have
          a priority greater than or equal to those granted to Holders pursuant
          to this Warrant without the prior written consent of the Holder(s).

               (d) The Company's obligations under Section 10(a) above with
          respect to each holder of Shares are expressly conditioned upon such
          holder's furnishing to the Company in writing such information
          concerning such holder and the terms of such holder's proposed
          offering as the Company shall reasonably request for inclusion in the
          registration statement. If any registration statement including any of
          the Shares is filed, then the Company shall indemnify each holder
          thereof (and each underwriter for such holder and each person, if any,

          12.  RIGHTS OF CO-SALE.

               (a) Co-Sale Right. Until such time as the Company completes an
          underwritten public offering raising at least $10,000,000.00, neither
          Empire National II, LLC, Charles R. Mollo, Jeffrey S. Doss, Cameron
          Wilson, nor Janice L. Breeze (individually a "Selling Shareholder" and
          collectively the "Selling Shareholders") shall enter into any
          transaction that would result in the sale by it of any Common Stock
          now or hereafter owned by it, unless prior to such sale the Selling
          Shareholder shall give notice to Holder of its intention to effect
          such sale in order that Holder may exercise its rights under this
          Section 12 as hereinafter described. Such notice shall set forth (i)
          the number of shares to be sold by the Selling Shareholder, (ii) the
          principal terms of the sale, including the price at which the shares
          are intended to be sold, and (iii) an offer by the Selling Shareholder
          to use its best efforts to cause to be included with the shares to be
          sold by it in the sale, on a share-by-share basis and on the same
          terms and conditions, the Shares issuable or issued to Holder pursuant
          this Warrant.

               (b) Rejection of Co-Sale Offer. If Holder has not accepted such
          offer in writing within a period of ten (10) days from the date of
          receipt of the notice, then the Selling Shareholder shall thereafter
          be free for a period of ninety (90) days to sell the number of shares
          specified in such notice, at a price no greater than the price set
          forth in such notice and on otherwise no more favorable terms to the
          Selling Shareholder than as set forth in such notice, without any
          further obligation to Holder in connection with such sale. In the
          event that the Selling Shareholder fails to consummate such sale
          within such ninety-day period, the shares specified in such notice
          shall continue to be subject to this Section.


                                       14

<PAGE>   15

               (c) Acceptance of Co-Sale Offer. If Holder accepts such offer in
          writing within ten (10) day period, such acceptance shall be
          irrevocable unless the Selling Shareholder shall be unable to cause to
          be included in his sale the number of Shares of stock held by Holder
          and set forth in the written acceptance. In that event, the Selling
          Shareholder and Holder shall participate in the sale pro rata based on
          their ownership.

               (d) Offers Not Covered. The restrictions under this Section 12
          will not apply to any sale or transfer of any Common Stock by a
          Selling Shareholder to immediate family members (parent, grandparent,
          spouse, children, grandchildren and siblings), or trusts for the
          benefit of such family members of such Selling Shareholder, or the
          estate of a Selling Shareholder as long as such transferee
          acknowledges that such Common Stock shall remain subject to the terms
          of this Section 12, as if held by a Selling Shareholder, and such
          transferee executes an agreement stating that it is bound by the terms
          of this Section 12 and will hold such shares of Common Stock subject
          to all such terms and conditions.

          13. EQUITY PARTICIPATION. This Warrant is issued in connection with
          the Loan Agreement. It is intended that this Warrant constitute an
          equity participation under and pursuant to T.C.A. Section 47-24-101,
          et seq. and that such equity participation be permitted under said
          statutes and not constitute interest on the Note. If under any
          circumstances whatsoever, fulfillment of any obligation of this
          Warrant, the Loan Agreement, or any other agreement or document
          executed in connection with the Loan Agreement, shall violate the
          lawful limit of any applicable usury statute or any other applicable
          law with regard to obligations of like character and amount, then the
          obligation to be fulfilled shall be reduced to such lawful limit, such
          that in no event shall there occur, under this Warrant, the Loan
          Agreement, or any other document or instrument executed in connection
          with the Loan Agreement, any violation of such lawful limit, but such
          obligation shall be fulfilled to the lawful limit. If any sum is
          collected in excess of the lawful limit, such excess shall be applied
          to reduce the principal amount of the Note.

          14. GOVERNING LAW. This warrant shall be governed by the laws of the
          State of Tennessee applicable to agreements made entirely within the
          State.

          15. SEVERABILITY. If any provision(s) of this Warrant or the
          application thereof to any person or circumstances shall be invalid or
          unenforceable to any extent, the remainder of this Warrant and the
          application of such provisions to other


                                       15

<PAGE>   16

          persons or circumstances shall not be affected thereby and shall be
          enforced to the greatest extent permitted by law.

          16. COUNTERPARTS. This Warrant may be executed in any number of
          counterparts and be different parties to this Warrant in separate
          counterparts, each of which when so executed shall be deemed to be an
          original and all of which taken together shall constitute one and the
          same Warrant.

          17. JURISDICTION AND VENUE. The Company hereby consents to the
          jurisdiction of the courts of the State of Tennessee and the United
          States District Court for the Middle District of Tennessee, as well as
          to the jurisdiction of all courts from which an appeal may be taken
          from such courts, for the purpose of any suit, action or other
          proceeding arising out of any of its obligations arising under this
          Agreement or with respect to the transactions contemplated hereby, and
          expressly waives any and all objections it may have as to venue in any
          such courts.

        2.8 INTELLECTUAL PROPERTY. The Company owns or possesses sufficient
title and ownership of or licenses to all patents, trademarks, service marks,
trade names, copyrights, trade secrets, licenses, information and proprietary
rights and processes necessary for its business as conducted and proposed to be
conducted without any conflict with, or infringement of, the rights of others.
There are no outstanding options, licenses or agreements of any kind relating to
the foregoing, nor is the Company bound by or a party to any options, licenses
or agreements of any kind with respect to the patents, trademarks, service
marks, trade names, copyrights, trade secrets, licenses, information and other
proprietary rights and processes of any other person or entity other

<PAGE>   6

than such licenses or agreements arising from the purchase of "off the shelf" or
standard commercial products. The Company has not received any communications
alleging that the Company has violated or, by conducting its business, would
violate any of the patents, trademarks, service marks, trade names, copyrights,
trade secrets or other proprietary rights or processes of any other person or
entity. The Company, to the best of its knowledge, is not aware that any of its
employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of such employee's best efforts to promote the interest of the Company
or that would conflict with the Company's business. To the best knowledge of the
Company, neither the execution or delivery of this Agreement, nor the carrying
on of the Company's business by the employees of the Company, nor the conduct of
the Company's business as proposed, will 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 such employee is now obligated.
The Company does not believe it is or will be necessary to use any inventions of
any of its employees (or persons it currently intends to hire) made prior to
their employment by the Company.

        2.9 COMPLIANCE WITH OTHER INSTRUMENTS.

            (a) The Company is not in violation or default of any provisions of
(i) its Certificate of Incorporation or Bylaws (as such documents are in force
and effect as of the Closing Date) or (ii) any instrument, judgment, order,
writ, decree or contract to which it is a party or by which it is bound, the
violation of, or default, which would have a material adverse effect on the
Company, or, to the best knowledge of the Company, of any provision of federal
or state statute, rule or regulation applicable to the Company. The execution,
delivery and performance of the Agreements and the consummation of the
transactions contemplated hereby or thereby will not result in any such
violation or be in conflict with or constitute, with or without the passage of
time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an event which results
in the creation of any lien, charge or encumbrance upon any assets of the
Company.

            (b) The Company has avoided every condition, and has not performed
any act, the occurrence of which would result in the Company's loss of any right
granted under any license, distribution agreement or other agreement.

        2.10 AGREEMENTS; ACTION.

            (a) There are no agreements, understandings or proposed transactions
between the Company and any of its officers, directors, affiliates, or any
affiliate thereof.

            (b) Except as created or incurred in the ordinary course of
business, as related to the Company's Universal Docking Station, or for
agreements explicitly contemplated by the Agreements, there are no agreements,
understandings, instruments, contracts or proposed


                                    Page 5
<PAGE>   7

transactions to which the Company or any of its subsidiaries is a party or by
which it is bound that involve (i) obligations (contingent or otherwise) of, or
payments to, the Company or any of its subsidiaries in excess of, $100,000, (ii)
the license of any patent, copyright, trade secret or other proprietary right to
or from the Company or any of its subsidiaries, (iii) the grant of rights
(excluding contract manufacturing rights and relationships) to manufacture,
produce, assemble, license, market, or sell its products to any other person or
affect the Company's exclusive right to develop, manufacture, assemble,
distribute, market or sell its products; or (iv) indemnification by the Company
with respect to infringement of proprietary rights (other than indemnification
obligations arising from purchase or sale agreements entered into in the
ordinary course of business).

            (c) Neither the Company nor any of its subsidiaries has (i) declared
or paid any dividends, or authorized or made any distribution upon or with
respect to any class or series of its capital stock, (ii) incurred any
indebtedness for money borrowed or incurred any other liabilities individually
in excess of $25,000 or in excess of $100,000 in the aggregate, other than in
the ordinary course of business, (iii) made any loans or advances to any person,
other than ordinary advances for travel and relocation expenses and the like, or
(iv) sold, exchanged or otherwise disposed of any of its assets or rights, other
than the sale of its inventory in the ordinary course of business.

        2.11 DISCLOSURE. The Company has fully provided Purchaser with all the
information that Purchaser has requested for deciding whether to acquire the
Stock and the Warrant and all information that the Company believes is
reasonably necessary to enable the Purchaser to make such a decision, including
the Company's 1999 Company Overview, dated September 1999 (the "Company
Overview"). No representation or warranty of the Company contained in this
Agreement and the exhibits attached hereto, any certificate furnished or to be
furnished to Purchaser at the Closing, or the Company Overview (when read
together) contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained herein or
therein not misleading in light of the circumstances under which they were made.
To the extent the Company Overview was prepared by management of the Company,
the Company Overview and the financial and other projections contained in the
Company Overview and other written information provided to the Purchaser were
prepared in good faith (with the exception of information prepared by third
party sources and identified as such in the Company Overview or other written
information and to which the Company makes no representation except that it has
no basis to believe such sections are inaccurate); however, the Company does not
warrant that it will achieve such projections.

        2.12 NO CONFLICT OF INTEREST. The Company is not indebted, directly or
indirectly, to any of its officers or directors or to their respective spouses
or children, in any amount whatsoever other than in connection with expenses or
advances of expenses incurred in the ordinary course of business or relocation
expenses of employees which amount does not in the aggregate exceed $50,000.
None of the Company's officers or directors, or any members of their immediate
families, are, directly or indirectly, indebted to the Company (other than in
connection with purchases of the



                                    Page 6
<PAGE>   8

Company's stock) or to the best knowledge of the Company have any direct or
indirect ownership interest in any firm or corporation with which the Company is
affiliated or with which the Company has a business relationship, or any firm or
corporation which competes with the Company except that officers, directors
and/or stockholders of the Company may own stock in (but not exceeding two
percent of the outstanding capital stock of) any publicly traded company that
may compete with the Company. None of the Company's officers or directors or any
members of their immediate families are, directly or indirectly, interested in
any material contract with the Company. The Company is not a guarantor or
indemnitor of any indebtedness of any other person, firm or corporation.

        2.13 RIGHTS OF REGISTRATION AND VOTING RIGHTS. Except as contemplated in
the Investors' Rights Agreement, the Company has not granted or agreed to grant
any registration rights, including piggyback rights, to any person or entity. To
the best knowledge of the Company, no stockholder of the Company has entered
into any agreements with respect to the voting of capital shares of the Company.

        2.14 TITLE TO PROPERTY AND ASSETS. The Company owns its property and
assets free and clear of all mortgages, liens, loans and encumbrances, except
such encumbrances and liens which arise in the ordinary course of business and
do not materially impair the Company's ownership or use of such property or
assets. With respect to the property and assets it leases, the Company is in
compliance with such leases and, to its knowledge, holds a valid leasehold
interest free of any liens, claims or encumbrances. The Company is in compliance
with all material terms of each material lease to which it is a party or
otherwise bound.

        2.15 FINANCIAL STATEMENTS. The Company has made available to Purchaser
the financial statements set forth in the Company Overview (collectively, the
"Financial Statements"). The Financial Statements have been prepared in
accordance with generally accepted accounting principles applied on a consistent
basis throughout the periods indicated, except that the unaudited Financial
Statements may not contain all footnotes required by generally accepted
accounting principles. The Financial Statements fairly present the financial
condition and operating results of the Company as of the dates, and for the
periods, indicated therein, subject to normal year-end audit adjustments. Except
as set forth in the Financial Statements, the Company has no material
liabilities, contingent or otherwise, other than (i) liabilities incurred in the
ordinary course of business subsequent to June 30, 1999 and (ii) obligations
under contracts and commitments incurred in the ordinary course of business and

with any employee, officer, director or stockholder;

benefit of its employees, officers or directors, or any members of their
immediate families, other than travel advances and other advances made in the
ordinary course of its business;

            (k) any declaration, setting aside or payment or other distribution
in respect to any of the Company's capital stock, or any direct or indirect

The Company has not made any elections pursuant to the Internal Revenue Code of
1986, as amended (the "Code") (other than elections that relate solely to
methods of accounting, depreciation or amortization) that would have a material
effect on the Company, its financial condition, its business as presently
conducted or proposed to be conducted or any of its properties or material
assets. The Company had never had any tax deficiency proposed or assessed

assessment or collection of any tax or governmental charge. None of the
Company's federal income tax returns and none of its state income or franchise

proper tax receiving officers or authorized depositories.

        2.19 INSURANCE. The Company has in full force and effect fire and

written or oral, express or implied, contract, commitment or arrangement with
any labor union, and no labor union has requested or, to the best knowledge of
the Company, has sought to represent any of the employees, representatives or

labor organization activity involving its employees. The Company is not aware
that any officer or key employee, or that any group of key employees, intends to
terminate their employment with the Company, nor does the Company have a present
intention to terminate the employment of any of the foregoing. The employment of
each officer and employee of the Company is terminable at the will of the
Company. The Company has complied in all material respects with all applicable
state and federal equal employment opportunity laws and with other laws related

Purchaser's representations and warranties set forth in Section 3 of this
Agreement, the offer, sale and issuance of the Securities as contemplated by

     3. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser hereby represents
and warrants to the Company that:

        3.1 AUTHORIZATION. Purchaser has full power and authority to enter into
this Agreement. The Agreements, when executed and delivered by Purchaser, will
constitute valid and legally binding obligations of Purchaser, enforceable in
accordance with their terms, except (a) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance, and any other
laws of general application affecting enforcement of creditors' rights
generally, and as limited by laws relating to the availability of a specific
performance, injunctive relief, or other equitable remedies, or (b) to the
extent the indemnification provisions contained in the Investors' Rights
Agreement may be limited by applicable federal or state securities laws.

        3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made with
Purchaser in reliance upon Purchaser's representation to the Company, which by
Purchaser's execution of this Agreement Purchaser hereby confirms, that the
Securities to be acquired by Purchaser will be acquired for investment for
Purchaser's own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof, and that Purchaser has no present


                                    Page 11
<PAGE>   13

intention of selling, granting any participation in, or otherwise distributing
the same. By executing this Agreement, Purchaser further represents that
Purchaser does not presently have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participation to such
person or to any third person, with respect to any of the Securities. Purchaser
has not been formed for the specific purpose of acquiring the Securities.

discuss the Company's business, management, financial affairs and the terms and

any other written information delivered by the Company to Purchaser, were
intended to describe the aspects of the Company's business which it believes to
be material.

        3.4 RESTRICTED SECURITIES. Purchaser understands that the Securities
have not been, and will not be, registered under the Securities Act, by reason

intent and the accuracy of Purchaser's representations as expressed herein.
Purchaser understands that the Securities are "restricted securities" under
applicable U.S. federal and state securities laws and that, pursuant to these
laws, Purchaser must hold the Securities indefinitely unless they are registered
with the Securities and Exchange Commission and qualified by state authorities,
or an exemption from such registration and qualification requirements is
available. Purchaser acknowledges that the Company has no obligation to register
or qualify the Securities for resale except as set forth in the Investors'
Rights Agreement. Purchaser further acknowledges that if an exemption from
registration or qualification is available, it may be conditioned on various
requirements including, but not limited to, the time and manner of sale, the
holding period for the Securities, and on requirements relating to the Company
which are outside of Purchaser's control, and which the Company is under no
obligation and may not be able to satisfy.

        3.5 NO PUBLIC MARKET. Purchaser understands that no public market now
exists for any of the securities issued by the Company, and that the Company has
made no assurances that a public market will ever exist for the Securities.

construed to be a waiver of any such breach or default, or an acquiescence
therein, or of or in any similar breach or default thereafter occurring; nor

breach or default theretofore or thereafter occurring. Any waiver, permit,

                   CONTRIBUTION AND INDEMNIFICATION AGREEMENT


         THIS CONTRIBUTION AND INDEMNIFICATION AGREEMENT (this "Agreement")
dated as of April 20, 1998, is executed by and among Janice L. Breeze
("Breeze"), Jeffrey S. Doss ("Doss"), Charles R. Mollo ("Mollo"), Cameron
Wilson ("Wilson" and collectively with Breeze, Doss and Mollo, the
"Guarantors"), Electronics Accessory Specialists International, Inc., a
Delaware corporation (the "Company"), and the stockholders of the Company set
forth on the signature pages hereto (the "Stockholders").

                                  WITNESSETH:

         WHEREAS, the Company has obtained from NationsBank, N.A. ("Lender"),
certain working capital lines of credit and will in the future obtain such
additional lines of credit (the "Loans") as evidenced by certain notes (the
"Notes"); and

         WHEREAS, as a condition to the funding of the Loans, Lender has
required and may require in the future that Guarantors execute and deliver
individual guaranties (the "Guaranty Agreements"), by which Guarantors agree to
guaranty payment of all or part of the Loans subject to the provisions therein
(all amounts owed by Guarantors under the Guaranty Agreements are referred to
herein as the "Guaranteed Sums"); and

         WHEREAS, the Guarantors and Stockholders have agreed to indemnify any
Indemnitee (as defined below) against amounts paid with respect to the
Guaranteed Sums in excess of that Indemnitee's pro rata share set forth on
Exhibit A;

         WHEREAS, in consideration of the agreements herein the Company has
agreed to issue to the Guarantors and Stockholders as a group purchase warrants
to purchase in the aggregate 225,000 shares of common stock of the Company, par
value $.01 per share (the "Common Stock"), at a price of $5.75 per share for a
period of five years (the "Warrants"); and

         WHEREAS, the parties hereto have determined that valuable benefits
will be derived by each party hereto as a result of the extensions of credit to
be made available to the Company pursuant to the Loans.

         NOW, THEREFORE, for valuable consideration, the receipt and
sufficiency of which are hereby acknowledged and confessed, each of the
undersigned agree as follows:

                                   ARTICLE I.
                   TERMS OF CONTRIBUTION AND INDEMNIFICATION

         1.01 Contribution and Indemnification. In connection with the Loans,
and as a condition to Lender providing funds under the Notes, Guarantors have
guaranteed, or in the future will guarantee, repayment of the Guaranteed Sums
pursuant to the Guaranty Agreements. In the event that any Guarantor (in such
capacity, each an "Indemnitee") pays any amounts on the Guaranteed

<PAGE>   2

Sums, whether through direct payments or as a result of providing collateral
for the Guaranteed Sums (the "Guaranty Payment"), Indemnitee shall be entitled
to receive from each Stockholder and Guarantor (in such capacity, each an
"Indemnitor"), such Indemnitor's pro rata percentage, as set forth in Exhibit
A, of the Guaranty Payment (the "Contribution Percentage"). If any Indemnitor
is unable to pay the Contribution Percentage of the Guaranty Payment, each
Stockholder and Guarantor agrees to make a contribution to Indemnitee to the
extent necessary so that each Stockholder and Guarantor shares pro rata (based
on the percentages set forth in Exhibit A) the liability for such nonpayment.
IN SUCH REGARD, TO THE MAXIMUM EXTENT PERMITTED BY LAW, EACH STOCKHOLDER AND
GUARANTOR SHALL INDEMNIFY, DEFEND, AND HOLD HARMLESS INDEMNITEE FROM AND
AGAINST ANY AND ALL LIABILITY, CLAIMS, COSTS AND EXPENSES (INCLUDING REASONABLE
ATTORNEYS' FEES AND EXPENSES) ARISING WITH RESPECT TO THE OBLIGATIONS AND
CONSTITUTING A GUARANTY PAYMENT.

         1.02 Payments. Any amount due to Indemnitee by an Indemnitor under
this Agreement shall be due and payable within ten (10) days of demand
therefore by Indemnitee. Interest shall accrue at the Default Rate (as defined
in the Notes) on amounts past due; provided, however, that in no event shall
interest accrue on such amounts at a rate in excess of the maximum rate of
interest permitted by applicable law and interest shall accrue from the date
payment is due to, but not including, the date payment is made and on the basis
of a year of three hundred sixty-five (365) or three hundred sixty-six (366)
days, as the case may be. All payments to be made by any Indemnitor under this
Agreement shall be made to Indemnitee at the address set forth under the names
set forth below, in immediately available funds, not later than 2:00 p.m.,
Scottsdale, Arizona time, on the date on which such payment shall come due
(each such payment made after such time on such due date shall be deemed to
have been made on the next succeeding business day and interest shall continue
to accrue until such time). If the due date of any payment under this Agreement
would otherwise fall on a day that is not a business day, such payment date
shall be extended to the next succeeding business day and interest shall be
payable for any principal so extended for the period of such extension.

         1.03 Non-Exclusive Remedy. The remedies available to Indemnitee
pursuant to the provisions of this Article I are not exclusive and, in such
regard, Indemnitee shall be entitled to join any Guarantor or Stockholder as a
party to any proceeding involving Indemnitee, any Guarantor, any Stockholder or
the Lender, including for purposes of enforcement of the provisions of this
Agreement.

         1.04 Term. The term of this Agreement (the "Term") shall commence as
of the date hereof and continue in effect until the earlier of: (a) the
Guaranteed Sums are terminated or extinguished (but not by reason of the
payment of the Guaranteed Sums by any party hereto in a proportion other than
as specified in Section 1.01); or (b) the two-year anniversary of the date of
this Agreement. Notwithstanding the above: (a) if the Company is unable to
terminate the Guaranty Agreements prior to the expiration of the Term, the
Guarantors shall have the right to demand payment of the Guaranteed Sums, in
which event, each Stockholder shall pay its portion of the Guaranteed Sums; and
(b) if any claim for payment of any Guaranteed Sums is made hereunder prior to
the expiration
<PAGE>   3
of the Term, Stockholders' obligation hereunder as to payment of their share of
such Guaranteed Sums shall continue until the resolution of such claim.

         1.05 Limitations. Notwithstanding anything in this Agreement to the
contrary: (a) the Guaranteed Sums will not exceed $4.7 million, unless
otherwise agreed to in writing by all Stockholders; and (b) after the second
anniversary of the date of this Agreement, the Company will use its best
efforts to cause the Guaranty Agreements to be terminated (whether by
refinancing or otherwise).
                                  ARTICLE II.
                                   WARRANTS

         2.01 Issuance and Cancellation of Warrants. The Company hereby agrees
to issue to each of the Guarantors and Stockholders the pro rata share of the
Warrants set forth on Exhibit A. If any Guarantor or Stockholder breaches their
obligations set forth in Article I of this Agreement, the unexercised portion
of the Warrants held by such person shall be canceled and the remaining
unexercised portion of those Warrants shall be reissued (pro rata based on
Exhibit A) by the Company to the nonbreaching Guarantors and Stockholders.

                            MISCELLANEOUS PROVISIONS

         3.01 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto, and their respective heirs, legal
representatives, and assigns.

         3.02 Amendments Waivers. Neither this Agreement nor any provision
hereof may be amended, waived, discharged, or terminated verbally, but only by
an instrument in writing signed by the party against whom enforcement of the
amendment, waiver, discharge, or termination is sought.

         3.03 Non-Waiver. It is understood and agreed that any delay, waiver,
or omission by any party hereto to exercise any right or power arising
hereunder shall not be construed to be a waiver by such party of any
subsequently arising right or power hereunder.

         3.04 Notices. Any notice, demand, offer, or other written instrument
required or permitted to be given pursuant to this Agreement shall be in
writing signed by the party giving such notice and shall be hand delivered or
sent by overnight courier, certified mail (return receipt requested), or
telefax to the other party(ies) at the relevant address set forth on the
signature pages below. Any party shall have the right to change the address to
which notice shall be sent or delivered to it hereunder by similar notice sent
in like manner to the other parties. A notice shall be deemed to be duly
received (a) if sent by hand, on the date when left with a responsible person
at the address of the recipient; (b) if sent by certified mail or overnight
courier, on the date of receipt by a responsible person at the address of the
recipient; or (c) if sent by telefax, upon receipt by the sender of an
acknowledgment or transmission report generated by the machine from which the
telefax was sent indicating that the telefax was sent in its entirety to the
recipient's telefax number.

         3.05 Attorneys' Fees. In the event any dispute between the parties to
this Agreement should result in litigation or any other proceeding (including
arbitration and mediation), the prevailing party shall be reimbursed by the
nonprevailing party for all reasonable costs and expenses, including reasonable
attorneys' fees, incurred by the prevailing party in connection with such
litigation or other proceeding and any appeal or enforcement thereof.

         3.06 Severability. If any term or provision of this Agreement or
application thereof to any person or circumstance shall to any extent be
invalid or unenforceable, the remainder of this Agreement, or the application
of such terms or provisions to persons or circumstances other than those as to
which it is invalid or unenforceable, shall not be affected thereby, and each
term and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by applicable law.

         3.07 Time of the Essence. The parties to this Agreement agree that
time is of the essence to the performance of the obligations of the parties
hereunder.

         3.08 Counterparts. The parties hereto may execute this Agreement in
multiple counterparts, all of which taken together shall constitute one and the
same instrument and each of which shall be deemed to be an original instrument
as against any party who has signed it.

OF THE PARTIES HERETO WITH RESPECT TO THE SUBJECT MATTER HEREOF AND SUPERSEDES
ALL PRIOR AGREEMENTS AND UNDERSTANDINGS, BOTH WRITTEN AND VERBAL, BETWEEN THE

                                                              WARRANT NO. A - _

             ELECTRONICS ACCESSORY SPECIALISTS INTERNATIONAL, INC.
                           d/b/a MOBILITY ELECTRONICS
                            (A DELAWARE CORPORATION)

                          FORM OF WARRANT TO PURCHASE
                             SHARES OF COMMON STOCK


NEITHER THIS WARRANT NOR THE SHARES ISSUABLE UPON ITS EXERCISE HAVE BEEN
REGISTERED UNDER EITHER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
ACT"), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, OFFERED FOR
SALE, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
EFFECTIVE REGISTRATION STATEMENT WITH RESPECT TO THE SECURITIES UNDER THE
SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS OR AN OPINION OF
COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

         THIS CERTIFIES THAT, for value received, _________________ or
registered assigns (hereinafter, the "Holder"), is entitled to purchase,
subject to the conditions set forth below, at any time or from time to time
during the Exercise Period (as defined in subsection 1.2, below),
_____________________________________ (______) shares ("Shares") of fully paid
and non- assessable common stock, par value $0.01 per share ("Common Stock"),
of ELECTRONICS ACCESSORY SPECIALISTS INTERNATIONAL, INC., a Delaware
corporation (the "Company"), at the per share purchase price (the "Warrant
Price") set forth in subsection 1.1, subject to the further provisions of this
Warrant. The term "Warrants" as used herein shall mean this Warrant and all
instruments issued by the Company which are substantially identical to this
Warrant (except for the name of the Holder and the number of securities
purchasable by the Holder).

1.       EXERCISE OF WARRANT

         The terms and conditions upon which this Warrant may be exercised, and
the Common Stock covered hereby may be purchased, are as follows:

         1.1      Warrant Price. The Warrant Price shall be Five Dollars and
75/100 ($5.75) per Share, subject to adjustment as provided in Section 4 below.

         1.2      Method Of Exercise. The Holder of this Warrant may, at any
time prior to April 20, 2003 exercise in whole or in part the purchase rights
evidenced by this Warrant. Such exercise shall be effected by:

                           (a)      the surrender of the Warrant, together with
                  a duly executed copy of the form of subscription attached
                  hereto, to the Secretary of the Company at its principal
                  offices;


<PAGE>   2


                           (b)      the payment to the Company, by certified
                  check or bank draft payable to its order, of an amount equal
                  to the aggregate Warrant Price for the number of Shares for
                  which the purchase rights hereunder are being exercised; and

                           (c)      the delivery to the Company, if necessary
                  to assure compliance with federal and state securities laws,
                  of an instrument executed by the Holder certifying that the
                  Shares are being acquired for the sole account of the Holder
                  and not with a view to any resale or distribution.

         As used herein "Sales Transaction" means: (i) the consolidation or
merger of the Company with or into any other corporation or business entity
(other than a consolidation or merger effected to change the state of
incorporation of the Company or effected with a principal purpose of causing
the exercise of the Warrants or the termination of the Exercise Period), (ii)
the sale or other transfer in a single transaction or a series of related
transactions of all or substantially all of the assets of the Company, or (iii)
the liquidation, dissolution, winding-up or reorganization of the Company.

         Notwithstanding the foregoing provisions requiring payment by check,
the Holder may from time to time at the Holder's option pay such Purchase Price
or any portion thereof by surrendering to the Company in lieu of such payment,
the right of such Holder to receive a number of shares of Common Stock having
an aggregate Market Value (as herein defined) equal to such Purchase Price (or
portion thereof) on the date of exercise (a "Cashless Exercise"). For purposes
of the foregoing, the term "Market Value" of a share of Common Stock as of a
relevant date means the closing price on the trading day preceding such date
with respect to the Common Stock on a national securities exchange, the Nasdaq
National Market or the Nasdaq Small-Cap Market. The closing price shall be (i)
the last sale price of shares of the Common Stock on such trading day or, if no
such sale takes place on such date, the average of the closing bid and asked
prices thereof on such date, in each case as officially reported on the
principal national securities exchange, the Nasdaq National Market or the
Nasdaq Small-Cap Market on which the Common Stock is then listed or admitted to
trading; or (ii) if no shares of Common Stock are then listed or admitted to
trading on any national securities exchange, the Nasdaq National Market or the
Nasdaq Small-Cap Market, the average of the reported closing bid and asked
prices thereof on such date in the over-the-counter market as shown on the
National Association of Securities Dealers automated quotation system. The
foregoing option of the Holder shall be of no force or effect unless the Common
Stock is then listed, admitted to trading, or reported.

         1.3      Satisfaction with Requirements of Securities Act of 1933.
Notwithstanding the provisions of subsection 1.2(c) and Section 7, each and
every exercise of this Warrant is contingent upon the Company's satisfaction
that the issuance of Common Stock upon the exercise is exempt from the
requirements of the Securities Act of 1933, as amended (the "Securities Act")
and all applicable state securities laws. The Holder of this Warrant agrees to
execute any and all documents determined necessary by the Company's counsel to
effect the exercise of this Warrant.

         1.4      Issuance Of Shares and New Warrant. In the event the purchase
rights evidenced by this Warrant are exercised in whole or in part, one or more
certificates for the purchased Shares shall be issued as soon as practicable
thereafter to the person exercising such rights. Such Holder shall


<PAGE>   3


also be issued at such time a new Warrant representing the number of Shares (if
any) for which the purchase rights under this Warrant remain unexercised and
continuing in force and effect.

2.       TRANSFERS

         2.1      Transfers. Subject to Sections 1.2 and 7 hereof, this Warrant
and all rights hereunder are transferable in whole or in part by the Holder.
The transfer shall be recorded on the books of the Company upon the surrender
of this Warrant, properly endorsed, to the Secretary of the Company at its
principal offices and the payment to the Company of all transfer taxes and
other governmental charges imposed on such transfer. In the event of a partial
transfer, the Company shall issue to the several Holders one or more
appropriate new Warrants.

         2.2      Registered Holder. Each Holder agrees that until such time as
any transfer pursuant to subsection 2.1 is recorded on the books of the
Company, the Company may treat the registered Holder of this Warrant as the
absolute owner; provided that nothing herein affects any requirement that
transfer of any Warrant or share of Common Stock issued or issuable upon the
exercise thereof by subject to securities law compliance.

         2.3      Form Of New Warrants. All Warrants issued in connection with
transfers of this Warrant shall bear the same date as this Warrant and shall be
substantially identical in form and provision to this Warrant, with the
possible exception of the number of Shares purchasable thereunder.

3.       FRACTIONAL SHARES

         Notwithstanding that the number of Shares purchasable upon the
exercise of this Warrant may have been adjusted pursuant to the terms hereof,
the Company shall nonetheless not be required to issue fractions of Shares upon
exercise of this Warrant or to distribute certificates that evidence fractional
shares nor shall the Company be required to make any cash payments in lieu
thereof upon exercise of this Warrant. Holder hereby waives any right to
receive fractional Shares. If a fractional Share shall result from adjustments
in the number of Shares purchasable hereunder, the number of Shares purchasable
hereunder shall, on an aggregate basis taking into account all adjustments
hereunder from the date of issuance of this Warrant, be rounded up to the next
whole number.

4.       ANTIDILUTION PROVISIONS

         The provisions of this Section 4 shall apply in the event that any of
the events described in this Section 4 shall occur with respect to the Common
Stock of the Company at any time on or after the original issuance date of this
Warrant.

         4.1      Stock Splits And Combinations. If the Company shall at any
time subdivide or combine its outstanding shares of 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 which were purchasable under this
Warrant immediately before that subdivision or combination. If the Company
shall at any time


<PAGE>   4


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 shall
become effective at the time that such subdivision or combination becomes
effective.

         4.2      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 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 for the same aggregate
consideration, in lieu of the Common Stock which the Holder would have become
entitled to purchase but for such change, the number of shares of such other
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.

         4.3      Reorganizations, Mergers, Consolidations Or Sale Of Assets.
If at any time there shall be a capital reorganization of the Common Stock
(other than a combination, reclassification, exchange, or subdivision of shares
provided for elsewhere above) then, as a part of such 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 Common Stock or other securities or property of the
Company, to which a holder of the 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. In
any such case, appropriate adjustment (as determined in good faith by the
Company's Board of Directors) shall be made in the application of the
provisions of this Warrant with respect to the rights and interests of the
Holder of this Warrant after the reorganization to the end that the provisions
of this Warrant (including adjustment of the Warrant Price then in effect and
number of Shares purchasable upon exercise of this Warrant) shall be applicable
after that event, as near as reasonably may be, in relation to any shares or
other property deliverable after that event upon exercise of this Warrant. The
Company shall, within thirty (30) days after making such adjustment, give
written notice (by first class mail, postage prepaid) to the registered Holder
of this Warrant at the address of that Holder shown on the Company's books.
That notice shall set forth, in reasonable detail, the event requiring the
adjustment and the method by which the adjustment was calculated and specify
the Warrant Price then in effect after the adjustment and the increased or
decreased number of Shares purchasable upon exercise of this Warrant. When
appropriate, that notice may be given in advance and include as part of the
notice required under other provisions of this Warrant.

         4.4      Common Stock Dividends; Distributions. In the event the
Company should at any time prior to the expiration of this Warrant fix a record
date for the determination of the holders of Common Stock entitled to receive a
dividend or other distribution payable in additional shares of Common Stock or
other securities or rights convertible into or entitling the holder thereof to
receive, directly or indirectly, additional shares of Common Stock (hereinafter
referred to as the "Common Stock Equivalents") without payment of any
consideration by such holder for the additional shares


<PAGE>   5


of Common Stock or Common Stock Equivalents (including the additional shares of
Common Stock issuable upon conversion or exercise thereof), then, as of such
record date (or the date of such distribution, split or subdivision if no
record date is fixed), the Warrant Price shall be appropriately decreased and
the number of shares of Common Stock issuable upon exercise of the Warrant
shall be appropriately increased in proportion to such increase of outstanding
shares.

         4.5      Adjustments of Other Distributions. In the event the Company
shall declare a distribution payable in securities of other persons, evidences
of indebtedness issued by the Company or other persons, assets (excluding cash
dividends) or options or rights not referred to in subsection 4.4, then, in
each such case for the purpose of this subsection 4.5, upon exercise of this
Warrant the Holder hereof shall be entitled to a proportionate share of any
such distribution as though such Holder was the holder of the number of shares
of Common Stock into which this Warrant may be exercised as of the record date
fixed for the determination of the holders of Common Stock of the Company
entitled to receive such distribution.

         4.6      Certificate as to Adjustments. In the case of each adjustment
or readjustment of the Warrant Price pursuant to this Section 4, the Company
will promptly compute such adjustment or readjustment in accordance with the
terms hereof and cause a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based, to be delivered to the Holder of this Warrant. The
Company will, upon the written request at any time of the Holder of this
Warrant, furnish or cause to be furnished to such Holder a certificate setting
forth:

                           (a)      Such adjustments and readjustments;

                           (b)      The purchase price at the time in effect;
                                    and

                           (c)      The number of shares of Common Stock
                                    issuable upon exercise of the Warrant and
                                    the amount, if any, of other property at
                                    the time receivable upon the exercise of
                                    the Warrant.

         4.7      Reservation of Stock Issuable Upon Exercise. 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
exercise of this Warrant such number of its shares of Common Stock as shall
from time to time be sufficient to effect the exercise of this Warrant and if
at any time the number of authorized but unissued shares of Common Stock shall
not be sufficient to effect the exercise of this Warrant, in addition to such
other remedies as shall be available to the Holder of this Warrant, the Company
will use its best efforts to 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 purposes.

5.       RIGHTS PRIOR TO EXERCISE OF WARRANT

         This Warrant does not entitle the Holder to any of the rights of a
stockholder of the Company, including without limitation, the right to receive
dividends of other distributions, to


<PAGE>   6


exercise any preemptive rights, to vote, or to consent or to receive notice as
a stockholder of the Company. If, however, at any time prior to the expiration
of this Warrant and prior to its exercise, any of the following events shall
occur:

                           (a)      the Company shall declare any dividend
                  payable in any securities upon its shares of Common Stock or
                  make any distribution (other than a cash dividend) to the
                  holders of its shares of Common Stock;

                           (b)      the Company shall offer to all of the
                  holders of its shares of Common Stock any additional shares
                  of Common Stock or securities convertible into or
                  exchangeable for shares of Common Stock or any right to
                  subscribe for or purchase any thereof; or

                           (c)      a dissolution, liquidation or winding up of
                  the Company (other than in connection with a consolidation,
                  merger, sale, transfer or lease of all or substantially all
                  of its property, assets, and business as an entirety) shall
                  be proposed and action by the Company with respect thereto
                  has been approved by the Company's Board of Directors,

the Company shall give notice in writing of such event to the Holder at his
last address as it shall appear on the Company's records at least twenty days
prior to the date fixed as a record date or the date of closing the transfer

distribution, or subscription rights, or for the determination of stockholders
entitled to vote on such proposed dissolution, liquidation or winding up. Such

transfer books of the Company are closed, such person shall be deemed to have
become the holder of such Shares at the close of business on the next
succeeding date on which the stock transfer books are open.

Project, shall be entitled to the exclusive use of up to 80% of the uncovered
parking spaces in the south parking lot between the hours of 11:00 p.m. and 5:30
a.m., and at all other times not more than 100 parking spaces in the Project;
TENANT SHALL BE ENTITLED TO THE EXCLUSIVE USE OF UP TO 77 SPACES IN THE SOUTH
PARKING LOT DURING REGULAR BUSINESS HOURS (M-F 8:00A.M.-5:00P.M.). Landlord
reserves the right to reduce the number of unreserved spaces available to Tenant
in the lot in front of the Building in order to satisfy reasonable requirements
for visitor or handicapped parking so long as the reduction is equitably shared
by all tenants having parking rights in that lot. Landlord also reserves the
right to mark uncovered spaces as reserved spaces, in which case Tenant's spaces
shall be marked with its name. Tenant shall have the non- exclusive use of the
truckwell in the south parking area in common with other tenants in the Project.
However, Tenant shall be subject to reasonable restrictions by Landlord on its
use and access to the truckwell at such times and on such days as Phoenix
Newspapers, Inc. receives its deliveries of printed newspapers for immediate
distribution.

3.6      Rules and Regulations. Tenant shall comply and shall cause its
employees to comply with the rules and regulations for the Project. The current
rules and regulations are attached as Exhibit D. Landlord from time to time by
notice to Tenant may amend the rules and regulations and establish other
reasonable non-discriminatory rules and regulations for the Project.

3.7      Compliance with Law. Without in any manner limiting any other provision
of this Lease, Tenant hereby warrants and agrees for the full term of any
obligations under this Lease:

         (b)      that Tenant will not dispose of nor permit or acquiesce in the
disposal of any hazardous or toxic waste (including, but not limited to, any

SOLE COST AND EXPENSE.

         (c)      to defend, INDEMNIFY and hold harmless Landlord for any and
all costs, claims, demands, damages including attorneys' fees and court costs
and investigatory and laboratory fees, related to any breach of this Lease by

condition (including without limitation any violation of Environmental Laws)
CAUSED BY TENANT during the term of this Lease. This indemnification to Landlord
shall survive the termination of the Lease by ONE YEAR FOR DISCOVERY OF SUCH
CONDITIONS OR RECEIPT OF CLAIMS, WHICHEVER IS FIRST TO OCCUR. HOWEVER, THE
INDEMNIFICATION SHALL SURVIVE THE TERMINATION OF THE LEASE BEYOND ONE YEAR FOR
PURPOSE OF DEFENDING CLAIMS MADE OR CURING BREACHES DISCOVERED DURING THE PERIOD
ENDING ONE YEAR AFTER THE TERMINATION OF THE LEASE.

         (d)      to comply with all reporting obligations imposed under the

         (f)      to use its best efforts to prevent any dumping, spillage,
leakage or runoff of substances regulated under. Environmental Laws ("Regulated
Substances") into dry wells, storm drains, water retention areas, Common Areas
or any areas where such substances could be absorbed into the soil;

         (g)      to obtain and maintain all permits required by federal, state
or local laws, rules or regulations;

         (h)      to prepare, and upon request provide a copy to Landlord of,
all response plans required by applicable law; and

         (i)      not to keep, store, or use within the Premises any Regulated

business and such quantities which are customarily associated with office usage,
such as copier AND CLEANING supplies.

3.8      Audit. UPON REASONABLE NOTICE, but not more than twice in any one year
(unless warranted by an incident CAUSED BY TENANT, ITS AGENTS OR EMPLOYEES)
Landlord may retain an environmental consultant or engineer to conduct an audit
or environmental assessment of the Premises and Tenant's compliance with
applicable laws, rules and regulations. Tenant shall extend its full cooperation
with the audit or investigation. If Tenant is found not to be substantially in
compliance with applicable law, all reasonable costs associated with AUDITS OR
ASSESSMENTS INITIATED FOLLOWING AN INCIDENT IN WHICH TENANT, ITS AGENTS OR
EMPLOYEES ARE FOUND RESPONSIBLE shall be paid by Tenant to Landlord upon demand;
otherwise all costs shall be borne by Landlord. In addition, Tenant, at
Landlord's request from time to time, shall complete such questionnaires and

ARTICLE 4   SECURITY DEPOSIT

UPON EXECUTION OF THIS LEASE TENANT SHALL BE CREDITED FOR ITS PRIOR DEPOSIT WITH

Tenant's performance of this Lease. The deposit shall not bear interest, shall
not be required to be maintained in a separate account, and shall be returned,
less any unpaid claims against Tenant, upon the expiration of this Lease and the
surrender of possession of the Premises, to Tenant or the last assignee of
Tenant's interest.

ARTICLE 5   RENT

5.1      Base Rent. Tenant shall pay to Landlord, in advance, on the first day
of each calendar month, beginning on the Commencement Date, Base Rent in the
amount set forth in Section 1.7, subject to adjustment under Section 5.2.

5.2      Adjustments. The Base Rent shall not be subject to adjustment during
the Initial Term hereunder (EXCEPT PURSUANT TO ARTICLE 26). IN THE EVENT TENANT
EXERCISES ITS TWO YEAR RENEWAL OPTION, THE BASE RENT



                                       4
<PAGE>   8



FOR THE RENEWAL TERM SHALL BE $.80 PER RENTABLE SQUARE FOOT PER MONTH. IN THE
EVENT TENANT EXERCISES ANY OF ITS THREE ONE YEAR RENEWAL OPTIONS FOLLOWING
EXERCISE OF ITS EXPANSION OPTION, THE BASE RENT FOR EACH OPTION TERM SHALL BE
ADJUSTED UPWARDS TO THE GREATER OF THE PREVAILING RATE FOR COMPARABLE SPACE IN
THE SCOTTSDALE AIRPARK, OR 5% HIGHER THAN THE BASE RENT FOR THE TERM THEN
ENDING.

5.3      Late Charges and Interest. Tenant shall pay to Landlord a late charge
equal to 5% of the Base Rent or any other amount payable under this Lease is not
paid within fifteen days after the date it is due and payable. The late charge
constitutes liquidated damages to compensate Landlord for costs and
inconveniences of special handling and disruption of cash flow and is not a
penalty. The assessment or collection of a late charge shall not constitute the
waiver of a default and shall not bar the exercise of other remedies for
nonpayment. In addition to the late charge, all amounts not paid within fifteen
days after the date due shall bear interest from the date due (i) until the
happening of an Event of Default, at the rate of 12% per annum and (ii)
thereafter, at the rate set forth in Section 21.2.

5.4      Excise Taxes. Tenant shall pay to Landlord all sales, use, transaction
privilege, or other excise tax levied, or imposed upon, or measured by, any
amount payable by Tenant under this Lease. IN ACCORDANCE WITH ARIZONA LAW,
TENANT'S PAYMENT OF ITS SHARE OF TENANT IMPROVEMENT COSTS OVER AND ABOVE THE
ALLOWANCE PROVIDED BY LANDLORD SHALL NOT BE SUBJECT TO THE TRANSACTION PRIVILEGE
TAX, EXCEPT THAT SUCH COSTS ARE INTENDED TO INCLUDE SALES TAX CHARGED BY THE
CONTRACTOR TO LANDLORD.

5.5      Obligations Are Rent. All amounts payable to Landlord under this Lease
constitute rent and shall be payable without notice, demand, deduction or offset
to such person and at such place as Landlord may from time to time designate by
written notice to Tenant.

5.6      Proration. Base Rent payable with respect to a period consisting of
less than a full calendar month shall be prorated.

ARTICLE 6   OPERATING COSTS

6.1      Tenant's Share. Tenant shall pay to Landlord Tenant's Proportionate
Share of the increase, if any, in Operating Costs for each calendar year above
the Operating Costs incurred in the calendar year 1997. TENANT'S PROPORTIONATE
SHARE OF THE INCREASE IN 1997 IS $0.00, BY DEFINITION.

6.2      Estimates. From time to time after the end of 1997, Landlord shall by
written notice specify Landlord's estimate of Tenant's obligation under Section
6.1. Tenant shall pay one-twelfth of the estimated annual obligation on the
first day of each calendar month.

6.3      Annual Reconciliation. Within 180 days after the end of each calendar
year, Landlord shall provide to Tenant a written summary of the Operating Costs
for the calendar year, determined on an accrual basis in accordance with
generally accepted accounting principles, and broken down by principal
categories of expense. The statement also shall set forth Tenant's Proportionate
Share of Operating Costs and shall show the amounts paid by Tenant on account.
Any difference between Tenant's obligation and the amounts paid by Tenant on
account shall be paid or refunded, as the case may be, within fifteen days after
the statement is provided. IN THE EVENT TENANT DISAGREES WITH SAID STATEMENT, IT
MAY, AT ITS SOLE COST AND EXPENSE, CONDUCT AN AUDIT TO VERIFY LANDLORD'S
RECONCILIATION BY A PRACTICING CPA. TENANT SHALL HAVE 120 DAYS FOLLOWING ITS
RECEIPT OF SAID STATEMENT TO CONDUCT ITS AUDIT AND LANDLORD AGREES TO TIMELY
PROVIDE ALL DOCUMENTATION REASONABLY REQUIRED BY THE CPA TO CONDUCT SAID AUDIT.
IN THE EVENT TENANT AND LANDLORD DISAGREE ON THE RESULTS OF TENANT'S AUDIT
FINDINGS, THEN A MUTUALLY AGREED TO CPA SHALL BE HIRED TO CONDUCT ITS OWN AUDIT.
COST OF THE JOINTLY APPOINTED CPA SHALL BE BORNE 50/50 BETWEEN LANDLORD AND
TENANT. THE RESULTS OF THE JOINTLY APPOINTED AUDIT SHALL BE FINAL AND BINDING.
FOLLOWING THE AUDIT(S), ANY REMAINING BALANCE DUE LANDLORD SHALL BE PAID
FORTHWITH, AND ANY ADJUSTMENT IN FAVOR OF TENANT SHALL BE REFUNDED TO TENANT
FORTHWITH.

6.4      Partial Year Proration; Variable Cost Adjustment. During the last year
of the Term, Tenant's responsibility for Operating Costs shall be adjusted in
the proportion that the number of days of that calendar year during which the
Lease is in effect bears to 365. Tenant's obligations under this Article 6 for
the payment of Operating Costs during the Lease Term, including the payment of
any deficiency following receipt of the annual statement under Section 6.3,
shall survive the expiration or termination of this Lease BY A PERIOD NOT TO
EXCEED ONE YEAR. LANDLORD'S OBLIGATIONS UNDER THIS ARTICLE 6 FOR THE PAYMENT OF
OPERATING COSTS DURING THE LEASE TERM, INCLUDING THE REFUNDING OF ANY
OVERPAYMENT BY TENANT FOLLOWING RECEIPT OF THE ANNUAL STATEMENT UNDER SECTION
6.3, SHALL SURVIVE THE EXPIRATION OR TERMINATION OF THIS LEASE BY A PERIOD NOT
TO EXCEED ONE YEAR. If the mean level of occupancy of the Building during a
calendar year is less than 100% of the



                                       5
<PAGE>   9



rentable area, the Operating Costs shall be adjusted to reflect the fact that
some costs, such as HVAC, vary with level of occupancy while other costs, such
as real estate taxes, may not. In order to allocate those variable costs to
Occupied space while allocating non-variable costs to occupied and unoccupied
space alike, Landlord shall determine, IN ITS REASONABLE DISCRETION, what the
total Operating Costs would have been had the Building been fully occupied
during the entire calendar year (AND THE YEAR 1997, IF APPLICABLE) on the
average, and that adjusted total shall be the figure employed in the statement
and calculations described in Sections 6.1 and 6.3.

6.5      "Operating Costs" consist of all costs of operating, maintaining and
repairing the Project, including, without limitation, the following:

         (a)      Premiums for property, casualty, liability, rent interruption
or other insurance.

         (b)      Reasonable salaries, wages and other amounts paid or payable

contributions and similar premiums and contributions and the total charges of
any independent contractors or managers engaged in the repair, care, maintenance
and cleaning of any portion of the Project, TO THE EXTENT TIME IS SPENT AND
WAGES AND OTHER AMOUNTS ARE PROPORTIONATELY ALLOCABLE.

         (c)      Cleaning, sweeping, restriping or sealcoating of parking
areas.

         (d)      Landscaping, including irrigating, trimming, mowing,

(REPLACEMENT COSTS BEING LIMITED BY 6.5(k)).

         (g)      Other items of repair or maintenance of the Project, including
roofing repairs and exterior painting not to exceed $7,500 per annum.

         (h)      Policing and security, if any, and sprinkler monitoring and
testing charges.

operation of the Project.

         (j)      Audit fees and the cost of accounting services incurred in the
preparation of statements referred to in this Lease and financial statements,
and in the computation of the rents and charges payable by tenants of the
Project.

         (k)      Costs of capital expenditures incurred for the purpose of
reducing Operating Costs, and costs of improvements, repairs, or replacements
which otherwise constitute Operating Costs under this Article but which are
properly charged to capital accounts shall not be included in Operating Costs in
a single year but shall instead be amortized over their useful lives, as
determined by the Landlord in accordance with generally accepted accounting
principles, and only the annual amortization amount shall be included in
Operating Costs.

         (l)      A reasonable fee for the administration and management of the
Project appropriate to the nature of the Project as reasonably determined by the
Landlord from time to time, but not in excess of prevailing market rates, AND
SUBJECT TO A MAXIMUM INCREASE, IF ANY, OF 5% PER ANNUM.


         (m)      Intentionally omitted.

         (n)      General and special real and personal property taxes and
assessments for the Project, including assessments payable to the Scottsdale
Airpark Property Owners' Association, and expenses incurred in efforts to reduce
taxes or assessments. Special assessments shall be included only to extent of
the annual installment if the assessment is payable over a period of years or if
an option to pay the assessment over a term of years exists.

         (o)      Refuse removal, to the extent not contracted for and paid
directly by other tenants. To the extent another Tenant contracts for a pays
directly for refuse removal, Tenant's Proportionate Share of refuse removal
costs shall be adjusted to the proportion that the area of the Premises bears to
the area of the Project less the area



                                       6
<PAGE>   10



of space leased to tenant contracting for separate refuse removal services.

6.6      Exclusions. Notwithstanding anything to the contrary in Section 6.5,
"Operating Costs" shall not include:

         (a)      Amounts reimbursed by other sources, such as insurance
proceeds, equipment warranties, judgments or settlements.

6.7      Excess Expenses. Notwithstanding anything to the contrary in this
Article 6, if any tenant's (including Tenant's) use or occupancy of its leased
premises results in expenditures for refuse removal, exterior lighting, or truck
driveway repair and maintenance in excess of what would be typical for a tenant
of a facility comparable to the Project, then the portion of such costs in
excess of typical levels of demand shall be excluded from Operating Costs.
Tenant shall pay to Landlord its allocable share of such costs (based on
Tenant's share of such excessive usage) directly to Landlord periodically upon
request. In the event of a dispute with respect to whether Tenant's use results
in excessive exterior lighting or truck driveway repair and maintenance, or over
the portion of such costs to be allocated to Tenant, a binding determination
shall be made by the regularly employed electrical or paving contractor familiar
with the Project. If requested, Tenant shall make monthly payments on account of
Tenant's obligations under this Section on an estimated basis, subject to annual
reconciliation in the same manner as Operating Costs. Landlord's obligations
with respect to record keeping and Tenant's rights to review related records
shall be the same as those related to records of Operating Costs. TENANT SHALL
ALSO BE RESPONSIBLE FOR THE COST OF ADDITIONS TO THE PROJECT'S ELECTRICAL OR
HVAC CAPACITY WARRANTED BY TENANT'S INSTALLATION OF ELECTRIC DEVICES AND
EQUIPMENT IN THE PREMISES WHICH INCREASE RECEPTACLE LOADS ABOVE 6.6 WATTS PER
SQUARE FOOT. AT THE TIME LANDLORD DETERMINES THAT THE THRESHOLD OF 6.6 WATTS PER
SQUARE FOOT HAS BEEN REACHED OR EXCEEDED, LANDLORD SHALL REVIEW TENANT'S
EQUIPMENT AND USAGE WITH TENANT AND DETERMINE THE EXTENT TO WHICH ADDITIONAL
CAPACITY MAY BE REQUIRED. LANDLORD SHALL NOT INSTALL ADDITIONAL CAPACITY AT
TENANT'S EXPENSE UNTIL AFTER PROVIDING TENANT WITH THE ESTIMATED COST THEREOF,
AND ALLOWING TENANT TO REDUCE ITS CAPACITY UTILIZATION.

ARTICLE 7         TAXES

7.1      Landlord shall pay before delinquent all general and special real
property taxes assessed or levied on the Project, to reimbursement under Article
6.

7.2      Tenant shall pay before delinquent all taxes levied or assessed upon,
measured by, or arising from (a) the

property manger as additional insureds.

         (e)      At all time during the Lease Term, Tenant shall procure and
maintain workers' compensation insurance in accordance with applicable law and
employer's liability insurance with a limit not less than $500,000 BODILY INJURY
EACH ACCIDENT; $500,000 BODILY INJURY BY DISEASE - EACH PERSON; AND $500,000
BODILY INJURY BY DISEASE - POLICY LIMIT.

8.2      Policy Requirements. Tenant's insurance policies shall:


         (a)      where applicable, contain the mortgagee's standard mortgage
clause and in any event a waiver of any subrogation rights which Tenant's
insurers may have against Landlord and against those for whom the Landlord is in
law responsible;

         (b)      be taken out with insurers reasonably acceptable to Landlord
and be in a form satisfactory from time to time to Landlord;

         (c)      be non-contributing and apply as primary and not as excess to,
any other insurance available to the Landlord;

         (d)      not be invalidated with respect to the interests of the
Landlord and the holder of any encumbrance on the Project by reason of any
breach or violation by Tenant of any warranties, representations, declarations
or conditions contained in the policies; and

         (e)      contain an undertaking by the insurers to notify the Landlord,
and the holder of any encumbrance on the Project designated by Landlord, in
writing not less than thirty days prior to any material change, cancellation or

insurance or, if required by Landlord, certified copies of each such insurance
policy: (a) as soon as practicable after the placing of the required insurance
and (b) periodically thereafter before expiration, renewal or replacement of the
policies then in force. No review or approval of any such insurance certificate
by Landlord shall derogate or diminish Landlord's rights or Tenant's
obligations. Tenant shall not take possession of the Premises without having
complied with the requirements of this Section.

8.4      Indemnity and Exculpation. Tenant shall defend, indemnify and hold
Landlord harmless from any and all claims arising from Tenant's use of the
Premises or the conduct of its business or from any activity, work, or thing
done, permitted or suffered by Tenant in or about the Premises, regardless of
fault or negligence which is imputed to Landlord as the owner of the PROJECT but
which involves a condition of the Premises within the control of Tenant, its
employees or contractors. Tenant shall not be required, however, to indemnify
Landlord against a claim arising from Landlord's active negligence, breach of
lease, breach of contract, or willful misconduct. Landlord shall not be liable
and Tenant hereby waives all claims for any damage to any property in or about
the Premises or the Project or injury or inconvenience to Tenant's business, by
or from any cause whatsoever (including without limiting the foregoing, rain or
water leakage of any character from the roof, windows,



                                       8
<PAGE>   12


walls, basement, pipes, plumbing works or appliances). Tenant acknowledges that
it is protecting itself against logs by maintaining appropriate insurance
coverage.

8.5      Landlord's Policies. No insurable interest is conferred upon Tenant
under any policies of insurance carried by Landlord, and Tenant shall not be
entitled to share or receive proceeds of any insurance policy carried by
Landlord.

ARTICLE 9   FIRE AND CASUALTY

9.1      Termination Rights. If all or part of the Premises is rendered
untenantable by damage from fire or other casualty which in Landlord's
reasonable determination cannot be substantially repaired (employing normal
construction methods without overtime or other premium) under applicable laws
and governmental regulations within, 180 days from the date of the fire or other
casualty, then either Landlord or Tenant may elect to terminate this Lease as of
the date of such casualty by written notice delivered to the other not later
than ten days after notice of such determination is given by Landlord. Landlord
shall provide its determination of the estimated time to restore the Premises
within thirty days after the casualty. IN THE EVENT THE LEASE IS TERMINATED AS A
RESULT OF THIS CLAUSE, RENT SHALL BE ABATED TO THE EXTENT OF THE DAMAGED AREA OR
UTILITY OF THE PREMISES, AND PRO RATED TO THE DATE OF THE CASUALTY. ANY UNEARNED
RENT PREVIOUSLY PAID BY TENANT SHALL BE REFUNDED BY LANDLORD.

9.2      Restoration. If in Landlord's reasonable determination the damage
caused by the fire or casualty can be substantially repaired (employing normal
construction methods without overtime or other premium) under applicable laws
and governmental regulations within 180 days from the date of the fire or other
casualty, or if neither party exercises its right to terminate under Section
9.1, Landlord shall repair such damage other than damage to furniture, chattels
or trade fixtures which do not belong to the Landlord, which shall be repaired
forthwith by Tenant at its own expense.

9.3      Abatement. During any period of restoration, the Base Rent payable by
Tenant shall be proportionately reduced to the extent that the Premises are
thereby rendered untenantable from the date of casualty until completion by
Landlord of the repairs to the Premises (or the part thereof rendered
untenantable) or until Tenant again uses the Premises (or the part thereof
rendered untenantable) in its business, whichever first occurs.

9.4      Demolition of Project. Notwithstanding anything to the contrary in
Section 9.1, if all or a substantial part (whether or not including the
Premises) of the Project is rendered untenantable by damage from fire or other
casualty to such a material extent that in the opinion of Landlord the Project
must be totally or partially demolished, whether or not to be reconstructed in
whole or in part, Landlord OR TENANT may elect to terminate this Lease as of the
date of the casualty (or on the date of notice if the Premises are unaffected by
such casualty) by written notice delivered to Tenant not more than sixty days
after the date of the fire or casualty.

9.5      Agreed Remedies. Except as specifically provided in this Article, there
shall be no reduction of rent and Landlord shall have no liability to Tenant by
reason of any injury to or interference with Tenant's business or property
arising from fire or other casualty, howsoever caused, or from the making of any
repairs resulting therefrom in or to any portion of the Project or the Premises.
Tenant waives any statutory or other rights of termination by reason of fire or
other casualty, it being the intention of the parties to provide specifically
and exclusively in this Article for the rights of the parties with respect to
termination of this Lease as a result of a casualty.

ARTICLE 10  CONDEMNATION

10.1     Automatic Termination. If during the Term all or any MATERIAL part of
the Premises is permanently taken for any public or quasi-public use under any
statute or by right of eminent domain, or purchased under threat of such taking,
this Lease shall automatically terminate on the date on which the condemning
authority takes possession of the Premises.

10.2     Optional Termination. If during the term any part of the Project is
taken or purchased by right of eminent domain or in lieu of condemnation,
whether or not the Premises are directly affected, then if in the reasonable
opinion of Landlord substantial alteration or reconstruction of the Project is
necessary or desirable as a result thereof, or the amount of parking available
to the Project is materially and adversely affected, Landlord shall have the
right to terminate this Lease by giving Tenant at least thirty days written
notice of such termination.




                                       9
<PAGE>   13

10.3     Award. Landlord shall be entitled to receive and retain the entire
award or consideration for the affected lands and improvements and Tenant shall
not have or advance any claims against Landlord for the value of its property or
its leasehold estate or the unexpired term of this Lease or for costs of removal
or relocation or business interruption expense or any other damages arising out
of the taking or purchase. Nothing herein shall give Landlord any interest in or
preclude Tenant from seeking and recovering on its own account from the
condemning authority any award of compensation attributable to the taking or
purchase of Tenant's chattels or trade fixtures or attributable to Tenant's
relocation expenses provided that any such separate claim by Tenant shall not
reduce or adversely affect the amount of Landlord's award. If any such award
made or compensation paid to Tenant specifically includes an award or amount for
Landlord, Tenant shall promptly account therefor to Landlord.

ARTICLE 11  MAINTENANCE

11.1     By Tenant. Tenant shall maintain the Premises and the improvements
therein (including all doors, plate glass, and electrical and plumbing systems
serving the Premises), in good condition and repair, utilizing licensed and
bonded contractors. Tenant shall provide all janitorial services required
for the Premises. IF LANDLORD, IN ITS REASONABLE DISCRETION, FINDS THE
PERFORMANCE OF TENANT'S CONTRACTOR(S) TO BE UNSATISFACTORY, OR IN ANY WAY
DETRIMENTAL TO THE OPERATION OF THE PROJECT, LANDLORD MAY REQUIRE TENANT TO
DISMISS SAID CONTRACTOR(S) AND PROVIDE NEW CONTRACTOR(S) ACCEPTABLE TO LANDLORD.
Tenant also shall make such repairs and alterations necessary to comply with the
requirements of any governmental or quasi-governmental authority having
jurisdiction which requirements are applicable based on Tenant's specific use,
of the Premises; Landlord shall bear the costs of alterations to comply with
governmental requirements of a general nature affecting any occupancy.

enjoyment.

additional ten days after notice that it was not received during the initial
ten-day period; or

         (c)      Tenant's failure to perform any other obligation under this
Lease within fifteen days after WRITTEN notice of nonperformance; provided,
however, that if the breach is of such a nature that it cannot be cured within
fifteen days, no Event of Default shall be deemed to have occurred by reason of
the breach if cure is commenced promptly and diligently pursued to completion
within a period not longer than ninety days; and provided further, that in the
event of a breach involving an imminent threat to health or safety, Landlord may
in its notice of breach reduce the period for cure to such shorter period as may
be reasonable under the circumstances; or

         (d)      Tenant vacates, abandons, or otherwise ceases to use the
Premises on a substantial continuing basis except temporary absence excused by
reason of fire, casualty, failure of services or other cause wholly beyond

days shall conclusively be deemed an abandonment.

21.2     Remedies. Upon the occurrence of an Event of Default, Landlord, at any
time thereafter without further notice or demand may exercise any one or more of
the following remedies concurrently or in succession:

reasonable efforts to mitigate Landlord's damages. In connection with any
reletting, Landlord may relet for a period extending beyond the term of this

Tenant of any liability. Upon a reletting of all or substantially all of the
Premises, Landlord shall be entitled to recover all of its then prospective
damages for the balance of the Lease Term measured by the present value of the
difference between amounts payable under this Lease and the anticipated net
proceeds of reletting.

         (c)      From time to time recover accrued and unpaid rent and damages
arising from Tenant's breach of the Lease, regardless of whether the Lease has
been terminated, together with applicable late charges and interest at the rate
of 18% per annum or the highest lawful rate, whichever is less.

         (d)      Enforce the statutory Landlord's lien on Tenant's property.

         (e)      Recover all costs, expenses and attorneys' fees incurred by
Landlord in connection with enforcing this Lease, recovering possession,
reletting the Premises or collecting amounts owed, including, without
limitation, costs of alterations, brokerage commissions, and other costs
incurred in connection with any reletting.

         (f)      Perform the obligation on Tenant's behalf and recover from
Tenant, upon demand, the entire


                                       14
<PAGE>   18


amount expended by Landlord plus 10% for special handling, supervision, and
overhead.

         (g)      Pursue other remedies available at law or in equity.

21.3     Subtenancies. Upon a termination of Tenant's right to possession,
whether or not this Lease is terminated: (a) subtenancies and other rights of

interest in such subleases or other arrangements shall be assigned to Landlord.
Landlord may separately elect termination or assignment with respect to each
such subtenancy or other matter.

21.4     DEFAULT BY LANDLORD. LANDLORD SHALL NOT BE IN DEFAULT UNLESS LANDLORD
FAILS TO PERFORM ITS OBLIGATIONS WITHIN FIFTEEN (15) DAYS AFTER WRITTEN NOTICE
FROM TENANT OF SUCH DEFAULT. IN THE EVENT THE NATURE OF THE ALLEGED DEFAULT IS
SOMETHING THAT REASONABLY REQUIRES MORE THAN FIFTEEN (15) DAYS TO CURE, LANDLORD
SHALL NOT BE DEEMED IN DEFAULT IF IT HAS, WITHIN THE FIFTEEN (15) DAY NOTICE
PERIOD, COMMENCED TO CURE THE DEFAULT AND DILIGENTLY PURSUES THE CURE UNTIL THE

contained in the Lease, and the sole right and remedy of the Tenant or any
subsequent sublessee or assignee shall be against Landlord's interest in the
Project. Neither Tenant nor any subsequent sublessor or assignee shall seek to
obtain any judgment imposing personal liability against Landlord, Landlord's
Affiliates, or their successors or assigns nor execute upon any judgment or
place any lien against any property other than Landlord's interest in the
Project. Landlord shall give written notice to Tenant of any change in ownership
affecting more than 50% of the ownership of Landlord.

ARTICLE 23  NOTICES

delivered, if personally delivered.

ARTICLE 25  GENERAL

25.1     Severability. If any term, covenant or condition of this Lease, or the
application thereof, is to any extent held or rendered invalid, it shall be and
is hereby deemed to be independent of the remainder of the Lease and to be
severable and divisible therefrom, and its invalidity, unenforceability or
illegality shall not affect, impair or invalidate the remainder of the Lease or
any part thereof

25.2     No Waiver. The waiver by Landlord, OR BY TENANT, of any breach of any
term, covenant or condition contained in this Lease shall not be deemed to be a
waiver of such term, covenant or condition or of any subsequent breach of the
same or of any other term, covenant or condition contained in this Lease. The
subsequent acceptance of rent by Landlord shall not be deemed to be a waiver of
any preceding breach by Tenant of any term, covenant or condition of this Lease,
regardless of Landlord's knowledge of such preceding breach at the time of
acceptance of rent. No term, covenant or condition of this Lease shall be deemed
to have been Waived by Landlord OR TENANT unless such waiver is in writing by
Landlord OR TENANT.

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

25.4     Delay. If either party is delayed or hindered in or prevented from the
performance of any term, covenant or act required hereunder by reasons of
strikes, labor troubles, inability to procure materials or services, power
failure, restrictive governmental laws or regulations, riots, insurrection,
sabotage, rebellion, war, act of God, or other reason whether of a like nature
or not that is beyond the control of the party affected, financial inability
excepted, then, IF NOTICE IS GIVEN WITHIN TEN (10) DAYS AFTER COMMENCEMENT OF
THE FORCE MAJEURE EVENT, the performance of that term, covenant or act is
excused for the period of the delay and the party delayed shall be entitled to
perform such term, covenant or act within the appropriate time period after the
expiration of the period of such delay. Nothing in this Section, however, shall
excuse Tenant from the prompt payment of any amount payable under this Lease nor
from the consequences of Tenant Delay as provided in Exhibit C (if attached).

25.5     Lender Notice. In the event of a material default by Landlord of a
sufficiently serious nature that Tenant considers the utility of the Premises to
Tenant to be significantly impaired, Tenant shall give written notice of the
default to Landlord and shall simultaneously send a copy of the notice to the
holder of any encumbrance, the name and address of whom has previously been
finished in writing to Tenant.

25.6     No Offer. The submission of this Lease for examination does not
constitute a reservation of an option to lease the Premises, and this Lease
becomes effective as a lease only upon its execution and delivery by Landlord
and Tenant.

25.7     Successors. All rights and liabilities under this Lease extend to and
bind the successors and assigns of Landlord and permitted successors and assigns
of Tenant. No rights, however, shall inure to the benefit of any transferee of

as provided in Section 16.1. If there is more than one Tenant, they are all
bound jointly and severally by the terms, covenants and conditions of this
Lease.

RENTABLE SQUARE FOOT FROM 1997. THE RESULTING RATES SHALL THEN BE BLENDED WITH
THE BASE RENT FOR THE (INITIAL) PREMISES TO ARRIVE AT THE BASE RENT FOR THE
TOTAL PREMISES OF 64,000+/- SQUARE FEET. BY WAY OF EXAMPLE, IF THE OPERATING
COSTS IN 1997 ARE ASSUMED TO BE $.17 PER SQUARE FOOT, THE BASE RENT OF THE
EXPANDED 64,000+/- SQUARE FEET WOULD INITIALLY BE:

CONCURRENTLY, TENANT'S PROPORTIONATE SHARE SHALL BE INCREASED TO THE PERCENTAGE
OF TENANT'S TOTAL RENTABLE AREA, DIVIDED BY THE TOTAL RENTABLE AREA OF THE
PROJECT. AS FURTHER CONSIDERATION FOR THE EXPANSION OPTION, THE INITIAL TERM
SHALL BE AUTOMATICALLY EXTENDED SO THAT THE EXPIRATION DATE IS FIVE YEARS FROM
THE DATE TENANT OCCUPIES THE EXPANDED PREMISES. THE EXPANSION OPTION, ONCE
EXERCISED, IS IRREVOCABLE BY TENANT. IF THE ORIGINAL EXPIRATION DATE IS TO OCCUR
PRIOR TO TENANT'S OCCUPANCY OF THE EXPANDED PREMISES, THE TERM SHALL CONTINUE
WITH BASE RENT AND OTHER CHANGES PAYABLE ON THE ORIGINAL 38,712 SQUARE FEET
UNTIL THE EXPANSION SPACE IS VACATED BY PHOENIX NEWSPAPERS, INC.

ARTICLE 27  RIGHT OF FIRST REFUSAL

27. IF DURING THE INITIAL TERM, OR ANY EXTENDED OR RENEWAL TERM HEREOF, ANY
SPACE BECOMES AVAILABLE FOR LEASE WITHIN THE PROJECT, TENANT SHALL ENJOY THE
RIGHT OF FIRST REFUSAL ON THAT SPACE AS FOLLOWS. UPON RECEIPT BY LANDLORD OF A
BONA FIDE OFFER TO LEASE FROM A TENANT, WHICH OFFER LANDLORD ELECTS TO ACCEPT
TENANT SHALL HAVE A PERIOD OF FIVE (5) BUSINESS DAYS FOLLOWING RECEIPT OF
LANDLORD'S NOTICE OF INTENT TO LEASE THE SPACE DURING WHICH TENANT MAY ELECT TO
LEASE THE AFFECTED SPACE ON THE SAME RATE AND TERMS AS OFFERED TO LANDLORD,
EXCEPT THAT TENANT'S LEASE TERM ON ITS CURRENT SPACE AND THE AFFECTED SPACE
SHALL BE EXTENDED TO THE PROSPECTIVE EXPIRATION DATE IN THE OFFER TO LEASE.
LANDLORD'S NOTICE OF INTENT TO LEASE MUST BE IN WRITING, BE SUFFICIENTLY CLEAR
AS TO EXPRESS THE RENTAL RATE, ANY ALTERATIONS TERMS, AND OTHER SALIENT TERMS,
SO THAT TENANT MAY MAKE AN INFORMED DECISION TO EXERCISE ITS RIGHT OF FIRST
REFUSAL. FAILURE OF TENANT TO RESPOND AFFIRMATIVELY EXERCISING ITS RIGHT TO
ENTER INTO THE LEASE OFFERED SHALL BE DEEMED A REJECTION OF THE OFFER. LANDLORD
SHALL THEREUPON BE FREE TO ENTER INTO THE LEASE WITH THE PARTY THAT MADE THE
OFFER ON TERMS NO LESS FAVORABLE THAN OFFERED TO TENANT. IF THE SAID LEASE IS
NOT CONSUMMATED WITHIN 60 DAYS FOLLOWING LANDLORD'S NOTICE, OR IF THE TERMS ARE
MADE MATERIALLY MORE FAVORABLE TO THE INTENDED LESSEE, TENANTS RIGHT OF FIRST
REFUSAL SHALL AGAIN BE EFFECTIVE AS TO THE SPACE IN QUESTION.

                             CONSTRUCTION PROVISIONS

1.       Space Plan. Attached to this Lease as Exhibit C-1 is a preliminary
space plan prepared by Architecture Plus (Job No.________, dated
_______________) approved by Landlord and Tenant showing the size, nature and
location of the improvements to be constructed in the Premises (the
"Improvements"). Promptly following execution of this Lease, Tenant shall meet
with Landlord's architect and shall provide such information and make such
selections as may be necessary for the expeditious completion of the planning
process. Exhibit C-1 expresses all of the demolition, alterations, and
improvements to be performed by Landlord ("Landlord's Work").

2.       Working Drawings. Landlord's Work shall not be commenced unless and
until working drawings prepared by Architecture Plus are completed and approved
in writing by Tenant.

3.       Cooperation. During the entire course of the process described above,
both Landlord and Tenant shall review and respond to submissions by the other
party with reasonable dispatch. Tenant shall respond with its approval or
comments within three days after receipt of initial drawings, specifications, or
other materials requiring Tenant's review and within three days after receipt of
revised versions of such documents or materials. From time to time at the
request of either party Landlord and Tenant shall devise, and revise as
necessary, working schedules for construction of the Improvements. Tenant shall
not permit any supplier, installer, contractor, or other person employed by
Tenant to interfere in any way with the progress of the work. Access by Tenant's
suppliers, contractors and installers shall be subject to (i) scheduling by
Landlord upon at least ten days' prior notice by Tenant, and (ii) compliance
with all requirements imposed by Landlord with respect to insurance,
cooperation, permits, licenses, bonding, hours of work, safety and use of
flammable substances.

4.       Cost. The working drawings shall be put out to bid to at least three
contractors of Landlord's choosing. Landlord shall inform Tenant of all bids and
shall choose the contractor for award of the job after consultation with Tenant.
To the extent the bid price, together with architectural fees, building permit
and plan check fees, and any related out of pocket costs to Landlord for the
Work exceeds $50,000, Tenant shall advance to Landlord payment of the excess, if
any, prior to commencement of the Work. In the event of change orders during the
completion of the Work, Tenant shall pay to Landlord the amount of additive
change orders above the $50,000 threshold, and Landlord shall refund to Tenant
from such advances the amount of any price reduction change orders.

5.       Punchlist. Within ten days after substantial completion of Landlord's
Work, Tenant shall deliver to Landlord a written punchlist specifying all
defects in materials or workmanship in the Improvements. Any defects not
specified in the punchlist, except latent defects not readily discoverable by
inspection, are waived. Landlord shall promptly cause all matters appearing on
the punchlist to be corrected.

6.       Delay. If completion of construction of Improvements within the
Premises is delayed by Tenant Delay, then the Commencement Date shall be deemed
to have occurred and rent shall begin to accrue as of the date when they would
have done so but for the Tenant Delay. "Tenant Delay" means delay as a result
of: (a) Tenant's failure to meet with the architect and to provide all required
information and make necessary selections for the expeditious development of
Plans; (b) Tenant's failure to provide comments on proposed Plans in a timely
manner; (c) Tenant's request for materials, finishes or installations requiring
more time to obtain, construct or install than Landlord's standard; or (d)
Tenant's change in any Plans after the revisions to the initial draft; or, (e)
performance or completion by a party employed by Tenant. Landlord shall not be
liable for any direct or consequential damages resulting from delayed delivery
of the Premises by reason of delayed construction or otherwise.

7.       Existing Equipment and Devices. Landlord shall be responsible, at its
sole cost and expense, for repairing or replacing, as necessary, all connected
electrical devices, heating, ventilation and air conditioning devices, plumbing
fixtures, light fixtures, fire sprinklers and related life safety devices, and
electrical devices prior to the Commencement Date, and shall warrant such
devices for a period of 90 days following the Commencement Date. Landlord makes
no warranty as to the adequacy or suitability of such devices for Tenant's use
and occupancy; only that such devices shall be in good working order for the
period of the 90 day warranty. Landlord makes no warranty, and is under no
obligation to service any existing security alarm, telephone wiring or devices
beyond the US West IMPOP, or pneumatic systems.

which have been furnished to Tenant, and in the event of loss of any keys so
furnished, shall pay Landlord therefor.

4.       Tenant shall not place a load upon any floor which exceeds the load per
square foot which such floor was designed to carry and which is allowed by law.

repaired at the expense of Tenant.

5.       Tenant shall close and lock the doors of its Premises and entirely shut

applicable federal, state and city laws, codes, ordinances, rules and
regulations.

9.       Landlord may waive any one or more of these Rules and Regulations for
the benefit of any particular tenant or tenants, but no such waiver by Landlord
shall be construed as a waiver of such Rules and Regulations in favor of any
other tenant or tenants, nor prevent Landlord from thereafter enforcing any such
Rules and Regulations against any or all of the tenants of the Building.

10.      These Rules and Regulations are in addition to, and shall not be

that Landlord has no further obligation or duty therefor. Tenant hereby
acknowledges and warrants to Landlord that it has had the opportunity to inspect
and familiarize itself with the Premises and has done so and accepts the same in
its current "AS IS, WHERE IS" condition, with all faults. This in no way alters
the Landlord's responsibilities under Section 11.2 of the Original Lease.

                   AMERICAN INDUSTRIAL REAL ESTATE ASSOCIATION

                                     [LOGO]


1.   PARTIES. This lease, dated, for reference purposes only, May 1, 1998, is
made by and between AIRPARK HOLDINGS I, L.L.C. (herein called "Lessor") and
E.A.S.I. (herein called "Lessee").

2.   PREMISES, PARKING AND COMMON AREAS.

     2.1 PREMISES. Lessor hereby leases to Lessee and Lessee leases from Lessor
for the term, at the rental, and upon all of the conditions set forth herein,
real property situated in the County of Maricopa, State of Arizona, commonly
known as 15690 N. 83rd Way, Scottsdale, AZ 85260 and described as approximately
20,000 sq. ft. of warehouse space herein referred to as the "Premises," as may
be outlined on an Exhibit attached hereto, including rights to the Common Areas
as hereinafter specified but not including any rights to the roof of the
Premises or to any Building in the Industrial Center. The Premises are a portion
of a building, herein referred to as the "Building." The Premises, the Building,
the Common Areas, the land upon which the same are located, along with all other
buildings and improvements thereon, are herein collectively referred to as the
"Industrial Center."

     2.2 VEHICLE PARKING. Lessee shall be entitled to common vehicle parking
spaces, unreserved and unassigned, on those portions of the Common Areas
designated by Lessor for parking. Lessee shall not use more parking spaces than
said number. Said parking spaces shall be used only for parking by vehicles no
larger than full size passenger automobiles or pick-up trucks, herein called
"Permitted Size Vehicles." Vehicles other than Permitted Size Vehicles are
herein referred to as "Oversized Vehicles."

         2.2.1 Lessee shall not permit or allow any vehicles that belong to or
are controlled by Lessee or Lessee's employees, suppliers, shippers, customers,
or invitees to be loaded, unloaded, or parked in areas other than those
designated by Lessor for such activities.

         2.2.2 If Lessee permits or allows any of the prohibited activities
described in paragraph 2.2 of this Lease, then Lessor shall have the right,
without notice, in addition to such other rights and remedies that it may have,
to remove or tow away the vehicle involved and charge the cost to Lessee, which
cost shall be immediately payable upon demand by Lessor.

     2.3 COMMON AREAS -- DEFINITION. The term "Common Areas" is defined as all
areas and facilities outside the Premises and within the exterior boundary line
of the Industrial Center that are provided and designated by the Lessor from
time to time for the general non-exclusive use of Lessor, Lessee and of other
lessees of the Industrial Center and their respective employees, suppliers,
shippers, customers and invitees, including parking areas, loading and unloading
areas, trash areas, roadways, sidewalks, walkways, parkways, driveways and
landscaped areas.

     2.4 COMMON AREAS -- LESSEE'S RIGHTS. Lessor hereby grants to Lessee, for
the benefit of Lessee and its employees, suppliers, shippers, customers and
invitees, during the term of this Lease, the non-exclusive right to use, in
common with others entitled to such use, the Common Areas as they exist from
time to time, subject to any rights, powers, and privileges reserved by Lessor
under the terms hereof or under the terms of any rules and regulations or
restrictions governing the use of the Industrial Center. Under no circumstances
shall be right herein granted to use the Common Areas be deemed to include the
right to store any property, temporarily or permanently, in the Common Areas.
Any such storage shall be permitted only by the prior written consent of Lessor
or Lessor's designated agent, which consent may be revoked at any time. In the
event that any unauthorized storage shall occur then Lessor shall have the
right, without notice, in addition to such other rights and remedies that it may
have, to remove the property and charge the cost to Lessee, which cost shall be
immediately payable upon demand by Lessor.

     2.5 COMMON AREAS -- RULES AND REGULATIONS. Lessor or such other person(s)
as Lessor may appoint shall have the exclusive control and management of the
Common Areas and shall have the right, from time to time, to establish, modify,
amend and enforce reasonable rules and regulations with respect thereto. Lessee
agrees to abide by and conform to all such rules and regulations, and to cause
its employees, suppliers, shippers, customers, and invitees to so abide and
conform. Lessor shall not be responsible to Lessee for the non-compliance with
said rules and regulations by other lessees of the Industrial Center.

     2.6 COMMON AREAS -- CHANGES. Lessor shall have the right, in Lessor's sole
discretion, from time to time:

         (a) To make changes to the Common Areas, including, without limitation,
changes in the location, size, shape and number of driveways, entrances, parking
spaces, parking areas, loading and unloading areas, ingress, egress, direction
of traffic, landscaped areas and walkways; (b) To close temporarily any of the
Common Areas for maintenance purposes, so long as reasonable access to the
Premises remains available; (c) To designate other land outside the boundaries
of the Industrial Center to be a part of the Common Areas; (d) To add additional
buildings and improvements to the Common Areas; (e) To use the Common Areas
while engaged in making additional improvements, repairs or alterations to the
Industrial Center, or any portion thereof; (f) To do and perform such other acts
and make such other changes in, to, or with respect to the Common Areas and
Industrial Center as Lessor may, in the exercise of sound business judgment,
deem to be appropriate.

         2.6.1 Lessor shall at all times provide the parking facilities required
by applicable law and in no event shall the number of parking spaces that Lessee
is entitled to under paragraph 2.2 be reduced.

3.   TERM.

     3.1 TERM. The term of this Lease shall be for month-to-month commencing on
May 1, 1998 and ending with on prior 30 day written notice from Lessee or
Lessor, unless sooner terminated pursuant to any provision hereof.

     3.2 DELAY IN POSSESSION. Notwithstanding said commencement date, if for any
reason Lessor cannot deliver possession of the Premises to Lessee on said date,
Lessor shall not be subject to any liability therefor, nor shall such failure
affect the validity of this Lease or the obligations of Lessee hereunder or
extend the term hereof, but in such case, Lessee shall not be obligated to pay
rent or perform any other obligation of Lessee under the terms of this Lease,
except as may be otherwise provided in this Lease, until possession of the
Premises is tendered to Lessee; provided, however, that if Lessor shall not have
delivered possession of the Premises within sixty (60) days from said
commencement date, Lessee may, at Lessee's option, by notice in writing to
Lessor within ten (10) days thereafter, cancel this Lease, in which event the
parties shall be discharged from all obligations hereunder; provided further,
however, that if such written notice of Lessee is not received by Lessor within
said ten (10) day period, Lessee's right to cancel this Lease hereunder shall
terminate and be of no further force or effect.

     3.3 EARLY POSSESSION. If Lessee occupies the Premises prior to said
commencement date, such occupancy shall be subject to all provisions of this
Lease, such occupancy shall not advance the termination date, and Lessee shall
pay rent for such period at the initial monthly rates set forth below.

4.   RENT.

     4.1 BASE RENT. Lessee shall pay to Lessor, as Base Rent for the Premises,
without any offset or deduction, except as may be otherwise expressly provided
in this Lease, on the 1st day of each month of the term hereof, monthly payments
in advance of $6,800.00 plus applicable rental tax. Lessee shall pay Lessor upon
execution hereof $6,929.20 as Base Rent for May 1998. Rent for any period during
the term hereof which is for less than one month shall be a pro rata portion of
the Base Rent. Rent shall be payable in lawful money of the United States to
Lessor at the address stated herein or to such other persons or at such other
places as Lessor may designate in writing.

<PAGE>   2

5.   SECURITY DEPOSIT. Lessee shall deposit with Lessor upon execution hereof
$-0- as security for Lessee's faithful performance of Lessee's obligations
hereunder. If Lessee fails to pay rent or other charges due hereunder, or
otherwise defaults with respect to any provision of this Lease, Lessor may use,
apply or retain all or any portion of said deposit for the payment of any rent
or other charge in default or for the payment of any other sum to which Lessor
may become obligated by reason of Lessee's default, or to compensate Lessor for
any loss or damage which Lessor may suffer thereby. If Lessor so uses or applies
all or any portion of said deposit, Lessee shall within ten (10) days after
written demand therefor deposit cash with Lessor in an amount sufficient to
restore said deposit to the full amount then required of Lessee. If the monthly
rent shall, from time to time, increase during the term of this Lease, Lessee
shall, at the time of such increase, deposit with Lessor additional money as a
security deposit so that the total amount of the security deposit held by Lessor
shall at all times bear the same proportion to the then current Base Rent as the
initial security deposit bears to the initial Base Rent set forth in paragraph
4. Lessor shall not be required to keep said security deposit separate from its
general accounts. If Lessee performs all of Lessee's obligations hereunder, said
deposit, or so much thereof as has not theretofore been applied by Lessor, shall
be returned, without payment of interest or other increment for its use, to
Lessee (or, at Lessor's option, to the last assignee, if any, of Lessee's
interest hereunder) at the expiration of the term hereof, and after Lessee has
vacated the Premises. No trust relationship is created herein between Lessor and
Lessee with respect to said Security Deposit.

6.   USE.

     6.1 USE. The Premises shall be used and occupied only for storage only or
any other use which is reasonably comparable and for no other purpose.

     6.2 COMPLIANCE WITH LAW.

         (a) Lessor warrants to Lessee that the Premises, in the state existing
on the date that the Lease term commences, but without regard to the use for
which Lessee will occupy the Premises, does not violate any covenants or
restrictions of record, or any applicable building code, regulation or ordinance
in effect on such Lease term commencement date. In the event it is determined
that this warranty has been violated, then it shall be the obligation of the
Lessor, after written notice from Lessee, to promptly, at Lessor's sole cost and
expense, rectify any such violation. In the event Lessee does not give to Lessor
written notice of the violation of this warranty within six months from the date
that the Lease term commences, the correction of same shall be the obligation of
the Lessee at Lessee's sole cost. The warranty contained in this paragraph
6.2(a) shall be of no force or effect if, prior to the date of this Lease,
Lessee was an owner or occupant of the Premises and, in such event, Lessor shall
correct any such violation at Lessee's sole cost.

         (b) Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's
expense, promptly comply with all applicable statutes, ordinances, rules,
regulations, orders, covenants and restrictions of record, and requirements of
any fire insurance underwriters or rating bureaus, now in effect or which may
hereafter come into effect, whether or not they reflect a change in policy from
that now existing, during the term or any part of the term hereof, relating in
any manner to the Premises and the occupation and use by Lessee of the Premises
and of the Common Areas. Lessee shall not use nor permit the use of the Premises
or the Common Areas in any manner that will tend to create waste or a nuisance
or shall tend to disturb other occupants of the Industrial Center.

   6.3 CONDITION OF PREMISES.

         (a) Lessor shall deliver the Premises to Lessee clean and free of
debris on the Lease commencement date (unless Lessee is already in possession)
and Lessor warrants to Lessee that the plumbing, lighting, air conditioning,
heating, and loading doors in the Premises shall be in good operating condition
on the Lease commencement date. In the event that it is determined that this
warranty has been violated, then it shall be the obligation of Lessor, after
receipt of written notice from Lessee setting forth with specificity the nature
of the violation, to promptly, at Lessor's sole cost, rectify such violation.
Lessee's failure to give such written notice to Lessor within thirty (30) days
after the Lease commencement date shall cause the conclusive presumption that
Lessor has complied with all of Lessor's obligations hereunder. The warranty
contained in this paragraph 6.3(a) shall be of no force or effect if prior to
the date of this Lease, Lessee was an owner or occupant of the Premises.

         (b) Except as otherwise provided in this Lease, Lessee hereby accepts
the Premises in their condition existing as of the Lease commencement date or
the date that Lessee takes possession of the Premises, whichever is earlier,
subject to all applicable zoning, municipal, county and state laws, ordinances
and regulations governing and regulating the use of the Premises, and any
covenants or restrictions of record, and accepts this Lease subject thereto and
to all matters disclosed thereby and by any exhibits attached hereto. Lessee
acknowledges that neither Lessor nor Lessor's agent has made any representation
or warranty as to the present or future suitability of the Premises for the
conduct of Lessee's business.

7.   MAINTENANCE, REPAIRS, ALTERATIONS AND COMMON AREA SERVICES.

     7.1 LESSOR'S OBLIGATIONS. Subject to the provisions of paragraphs 4.2
(Operating Expenses), 6 (Use), 7.2 (Lessee's Obligations) and 9 (Damage or
Destruction) and except for damage caused by any negligent or intentional act or
omission of Lessee, Lessee's employees, suppliers, shippers, customers, or
invitees, in which event Lessee shall repair the damage. Lessor, at Lessor's
expense, subject to reimbursement pursuant to paragraph 4.2, shall keep in good
condition and repair the foundations, exterior walls, structural condition of
interior bearing walls, and roof of the Premises, as well as the parking lots,
walkways, driveways, landscaping, fences, signs and utility installations of the
Common Areas and all parts thereof, as well as providing the services for which
there is an Operating Expense pursuant to paragraph 4.2. Lessor shall not,
however, be obligated to paint the exterior or interior surface of exterior
walls, nor shall Lessor be required to maintain, repair or replace windows,
doors or plate glass of the Premises. Lessor shall have no obligation to make
repairs under this paragraph 7.1 until a reasonable time after receipt of
written notice from Lessee of the need for such repairs. Lessee expressly waives
the benefits of any statute now or hereafter in effect which would otherwise
afford Lessee the right to make repairs at Lessor's expense or to terminate this
Lease because of Lessor's failure to keep the Premises in good order, condition
and repair. Lessor shall not be liable for damages or loss of any kind or nature
by reason of Lessor's failure to furnish any Common Area Services when such
failure is caused by accident, breakage, repairs, strikes, lockout, or other
labor disturbances or disputes of any character, or by any other cause beyond
the reasonable control of Lessor.

     7.2 LESSEE'S OBLIGATIONS.

         (a) Subject to the provisions of paragraphs 6 (Use), 7.1 (Lessor's
Obligations), and 9 (Damage or Destruction), Lessee, at Lessee's expense shall
keep in good order, condition and repair the Premises and every part thereof
(whether or not the damaged portion of the Premises or the means of repairing
the same are reasonably or readily accessible to Lessee) including, without
limiting the generality of the foregoing, all plumbing, heating, ventilating and
air conditioning systems (Lessee shall procure and maintain, at Lessee's
expense, a ventilating and air conditioning system maintenance contract),
electrical and lighting facilities and equipment within the Premises, fixtures,
interior walls and interior surfaces of exterior walls, ceilings, windows,
doors, plate glass, and skylights located within the Premises. Lessor reserves
the right to procure and maintain the ventilating and air conditioning system
maintenance contract and if Lessor so elects, Lessee shall reimburse Lessor,
upon demand, for the cost thereof.

         (b) If Lessee fails to perform Lessee's obligations under this
paragraph 7.2 or under any other paragraph of this Lease, Lessor may enter upon
the Premises after ten (10) days' prior written notice to Lessee (except in the
case of emergency, in which no notice shall be required), perform such
obligations on Lessee's behalf and put the Premises in good order, condition and
repair, and the cost thereof together with interest thereon at the maximum rate
then allowable by law shall be due and payable as additional rent to Lessor
together with Lessee's next Base Rent installment.

         (c) On the last day of the term hereof, or on any sooner termination,
Lessee shall surrender the Premises to Lessor in the same condition as received,
ordinary wear and tear excepted, clean and free of debris. Any damage or
deterioration of the Premises shall not be deemed ordinary wear and tear if the
same could have been prevented by good maintenance practices. Lessee shall
repair any damage to the Premises occasioned by the installation or removal of
Lessee's trade fixtures, alterations, furnishings and equipment. Notwithstanding
anything to the contrary otherwise stated in this Lease, Lessee shall leave the
air lines, power panels, electrical distribution systems, lighting fixtures,
space heaters, air conditioning, plumbing and fencing of the Premises in good
operating condition.

     7.3 ALTERATIONS AND ADDITIONS.

         (a) Lessee shall not, without Lessor's prior written consent make any
alterations, improvements, additions, or Utility Installations in, on or about
the Premises, or the Industrial Center, except for nonstructural alterations to
the Premises not exceeding $2,500 in cumulative costs, during the term of this
Lease. In any event, whether or not in excess of $2,500 in cumulative cost,
Lessee shall make no change or alteration to the exterior of the Premises nor
the exterior of the Building nor the Industrial Center without Lessor's prior
written consent. As used in this paragraph 7.3 the term "Utility Installation"
shall mean carpeting, window coverings, air lines, power panels, electrical
distribution systems, lighting fixtures, space heaters, air conditioning,
plumbing, and fencing. Lessor may require that Lessee remove any or all of said
alterations, improvements, additions or Utility Installations at the

                                      -2-
<PAGE>   3
expiration of the term, and restore the Premises and the Industrial Center to
their prior condition. Lessor may require Lessee to provide Lessor, at Lessee's
sole cost and expense, a lien and completion bond in an amount equal to one and
one-half times the estimated cost of such improvements, to insure Lessor against
any liability for mechanic's and materialmen's liens and to insure completion of
the work. Should Lessee make any alterations, improvements, additions or Utility
Installations without the prior approval of Lessor, Lessor may, at any time
during the term of this Lease, require that Lessee remove any or all of the
same.

         (b) Any alterations, improvements, additions or Utility Installations
in or about the Premises or the Industrial Center that Lessee shall desire to
make and which requires the consent of the Lessor shall be presented to Lessor
in written form, with proposed detailed plans. If Lessor shall give its consent,
the consent shall be deemed conditioned upon Lessee acquiring a permit to do so
from appropriate governmental agencies, the furnishing of a copy thereof to
Lessor prior to the commencement of the work and the compliance by Lessee of all
conditions of said permit in a prompt and expeditious manner.

         (c) Lessee shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Lessee at or for use in
the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises, or the Industrial Center, or any
interest therein. Lessee shall give Lessor not less than ten (10) days' notice
prior to the commencement of any work in the Premises, and Lessor shall have the
right to post notices of non-responsibility in or on the Premises or the
Building as provided by law. If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend itself and Lessor against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises or the Industrial Center, upon the
condition that if Lessor shall require, Lessee shall furnish to Lessor a surety
bond satisfactory to Lessor in an amount equal to such contested lien claim or
demand indemnifying Lessor against liability for the same and holding the
Premises and the Industrial Center free from the effect of such lien or claim.
In addition, Lessor may require Lessee to pay Lessor's attorney's fees and costs
and participating in such action if Lessor shall decide it is to Lessor's best
interest to do so.

         (d) All alterations, improvements additions and Utility Installations
(whether or not such Utility Installations constitute trade fixtures of Lessee),
which may be made on the Premises, shall be the property of Lessor and shall
remain upon and be surrendered with the Premises at the expiration of the Lease
term, unless Lessor requires their removal pursuant to paragraph 7.3(a).
Notwithstanding the provisions of this paragraph 7.3(d), Lessee's machinery and
equipment, other than that which is affixed to the Premises so that it cannot be
removed without material damage to the Premises, and other than Utility
Installations, shall remain the property of Lessee and may be removed by Lessee
subject to the provisions of paragraph 7.2.

     7.4 UTILITY ADDITIONS. Lessor reserves the right to install new or
additional utility facilities throughout the Building and the Common Areas for
the benefit of Lessor or Lessee, or any other lessee of the Industrial Center,
including, but not by way of limitation, such utilities as plumbing, electrical
systems, security systems, communication systems, and fire protection and
detection systems, so long as such installations do not unreasonably interfere
with Lessee's use of the Premises.

8.  INSURANCE; INDEMNITY.

     8.1 LIABILITY INSURANCE-LESSEE. Lessee shall, at Lessee's expense, obtain
and keep in force during the term of this Lease a policy of combined Single
Limit Bodily Injury and Property Damage Insurance insuring Lessee and Lessor
against any liability arising out of the use, occupancy or maintenance of the
Premises and the Industrial Center. Such Insurance shall be in an amount not
less than $500,000.00 per occurrence. The policy shall insure performance by
Lessee of the indemnity provisions of this paragraph 8. The limits of said
insurance shall not, however, limit the liability of Lessee hereunder.

     8.2 LIABILITY INSURANCE-LESSOR. Lessor shall obtain and keep in force
during the term of this Lease a policy of Combined Single Limit Bodily Injury
and Property Damage Insurance, Insuring Lessor, but not Lessee, against any
liability arising out of the ownership, use, occupancy or maintenance of the
Industrial Center in an amount not less than $500,000.00 per occurrence.

     8.3 PROPERTY INSURANCE. Lessor shall obtain and keep in force during the
term of this Lease a policy or policies of insurance covering loss or damage to
the Industrial Center Improvements, but not Lessee's personal property,
fixtures, equipment or tenant improvements, in an amount not to exceed the full
replacement value thereof, as the same may exist from time to time, providing
protection against all perils included within the classification of fire,
extended coverage, vandalism, malicious mischief, flood (in the event same is
required by a lender having a lien on the Premises), special extended perils
("all risk," as such term is used in the insurance industry), plate glass
insurance and such other insurance as Lessor deems advisable. In addition,
Lessor shall obtain and keep in force, during the term of this Lease, a policy
of rental value insurance covering a period of one year, with loss payable to
Lessor, which insurance shall also cover all Operating Expenses for said period.

     8.4 PAYMENT OF PREMIUM INCREASE.

         (a) After the term of this Lease has commenced, Lessee shall not be
responsible for paying Lessee's Share of any increase in the property insurance
premium for the Industrial Center specified by Lessor's insurance carrier as
being caused by the use, acts or omissions of any other lessee of the Industrial
Center, or by the nature of such other lessee's occupancy which create an
extraordinary or unusual risk.

         (b) Lessee, however, shall pay the entirety of any increase in the
property insurance premium for the Industrial Center over what it was
immediately prior to the commencement of the term of this Lease if the increase
is specified by Lessor's insurance carrier as being caused by the nature of
Lessee's occupancy or any act or omission of Lessee.

         (c) Lessee shall pay to Lessor, during the term hereof, in addition to
the rent, Lessee's Share (as defined in paragraph 4.2(a)) of the amount of any
increase in premiums for the insurance required under paragraphs 8.2 and 8.3
over and above such premiums paid during the Base Period, as hereinafter
defined, whether such premium increase shall be the result of the nature of
Lessee's occupancy, any act or omission of Lessee, requirements of the holder of
a mortgage or deed of trust covering the Premises, increased valuation of the
Premises, or general rate increases. In the event that the Premises have been
occupied previously, the words "Base Period" shall mean the last twelve months
of the prior occupancy. In the event that the Premises have never been occupied
previously, the premiums during the "Base Period" shall be deemed to be the
lowest premiums reasonably obtainable for said insurance assuming the most
nominal use of the Premises. Provided, however, in lieu of the Base Period, the
parties may insert a dollar amount at the end of this sentence which figure
shall be considered as the insurance premium for the Base Period: $__________.
In no event, however, shall Lessee be responsible for any portion of the premium
cost attributable to liability insurance coverage in excess of $500,000.00
procured under paragraph 8.2.

         (d) Lessee shall pay any such premium increases to Lessor within 30
days after receipt by Lessee of a copy of the premium statement or other
satisfactory evidence of the amount due. If the insurance policies maintained
hereunder cover other improvements in addition to the Premises. Lessor shall
also deliver to Lessee a statement of the amount of such increase attributable
to the Premises and showing in reasonable detail, the manner in which such
amount was computed. If the term of this Lease shall not expire concurrently
with the expiration of the period covered by such insurance. Lessee's liability
for premium increases shall be prorated on an annual basis.

     8.5 INSURANCE POLICIES. Insurance required hereunder shall be in companies
holding a "General Policyholders Rating" of at least B plus, or such other
rating as may be required by a lender having a lien on the Premises, as set
forth in the most current issue of "Best's Insurance Guide." Lessee shall not do
or permit to be done anything which shall invalidate the insurance policies
carried by Lessor. Lessee shall deliver to Lessor copies of liability insurance
policies required under paragraph 8.1 or certificates evidencing the existence
and amounts of such insurance within seven (7) days after the commencement date
of this Lease. No such policy shall be cancelable or subject to reduction of
coverage or other modification except after thirty (30) days prior written
notice to Lessor. Lessee shall, at least thirty (30) days prior to the
expiration of such policies, furnish Lessor with renewals or "binders" thereof.

     8.6 WAIVER OF SUBROGATION. Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other
for loss or damage arising out of or incident to the perils insured against
which perils occur in, on or about the Premises, whether due to the negligence
of Lessor or Lessee or their agents, employees, contractors and/or invitees.
Lessee and Lessor shall, upon obtaining the policies of insurance required
hereunder, give notice to the insurance carrier or carriers that the foregoing
mutual waiver of subrogation is contained in this Lease.

     8.7 INDEMNITY. Lessee shall indemnify and hold harmless Lessor from and
against any and all claims arising from Lessee's use of the Industrial Center,
or from the conduct of Lessee's business or from any activity, work or things
done, permitted or suffered by Lessee in or about the Premises or elsewhere and
shall further indemnify and hold harmless Lessor from and against any and all
claims arising from any breach or default in the performance of any obligation
on Lessee's part to be performed under the terms of this Lease, or arising from
any act or omission of Lessee, or any of Lessee's agents, contractors, or
employees, and from and against all costs, attorney's fees, expenses and
liabilities incurred in the defense of any such claim or any action or
proceeding brought thereon, and in case any action or proceeding be brought
against Lessor by reason of any such claim. Lessee upon notice from Lessor shall
defend the same at Lessee's expense by counsel reasonably satisfactory to Lessor
and Lessor shall cooperate with Lessee in such defense. Lessee, as a material
part of the consideration to Lessor, hereby assumes all risk of damage to
property of Lessee or injury to persons, in, upon or about the Industrial Center
arising from any cause and Lessee hereby waives all claims in respect thereof
against Lessor.

     8.8 EXEMPTION OF LESSOR FROM LIABILITY. Lessee hereby agrees that Lessor
shall not be liable for injury to Lessee's business or any loss of income
therefrom or from damage to the goods, wares, merchandise or other property of
Lessee, Lessee's employees, invitees, customers, or any other person in or about
the Premises or the Industrial Center, nor shall Lessor be liable for injury to
the person of Lessee, Lessee's employees, agents or contractors, whether such
damage or injury is caused by or results from fire, steam, electricity, gas,
water or rain, or from the breakage, leakage, obstruction or other results from
conditions arising upon the Premises or upon other portions of the Industrial
Center, or from other sources or places and regardless of whether the cause of
such damage or injury or the means of repairing the same is inaccessible to
Lessee. Lessor shall not be liable for any damages arising from any act or
neglect of any other lessee, occupant or user of the Industrial Center, nor from
the failure of Lessor to enforce the provisions of any other lease of the
Industrial Center.

9.5, if at any time during the term of this Lease there is damage which is not
an Insured Loss and which falls within the classification of Premises Partial

willful act of Lessee (in which event Lessee shall make the repairs at Lessee's
expense), which damage prevents Lessee from using the Premises, Lessor may at
Lessor's option either (i) repair such damage as soon as reasonably possible at
Lessor's expense, in which event this Lease shall continue in full force and
effect, or (ii) give written notice to Lessee within thirty (30) days after the
date of the occurrence of such damage of Lessor's intention to cancel and
terminate this Lease as of the date of the occurrence of such damage. In the
event Lessor elects to give such notice of Lessor's intention to cancel and
terminate this Lease, Lessee shall have the right within ten (10) days after the
receipt of such notice to give written notice to Lessor of Lessee's intention to
repair such damage at Lessee's expense, without reimbursement from Lessor, in
which event this Lease shall continue in full force and effect, and Lessee shall

shall be cancelled and terminated as of the date of the occurrence of such
damage.

     9.4 DAMAGE NEAR END OF TERM.

         (a) Subject to paragraph 9.4(b), if at any time during the last six
months of the term of this Lease there is substantial damage, whether or not an
Insured Loss, which falls within the classification of Premises Partial Damage,

occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within 30 days after the date of occurrence of such damage.

         (b) Notwithstanding paragraph 9.4(a), in the event that Lessee has an
option to extend or renew this Lease, and the time within which said option may
be exercised has not yet expired, Lessee shall exercise such option, if it is to
be exercised at all, no later than twenty (20) days after the occurrence of an
Insured Loss falling within the classification of Premises Partial Damage,
during the last six months of the term of this Lease. If Lessee duly exercises

     9.5 ABATEMENT OF RENT; LESSEE'S REMEDIES.

         (a) In the event Lessor repairs or restores the Premises pursuant to
the provisions of this paragraph 9, the rent payable hereunder for the period
during which such damage, repair or restoration continues shall be abated in
proportion to the degree to which Lessee's use of the Premises is impaired.
Except for abatement of rent, if any, Lessee shall have no claim against Lessor
for any damage suffered by reason of any such damage, destruction, repair or
restoration.

         (b) If Lessor shall be obligated to repair or restore the Premises
under the provisions of this paragraph 9 and shall not commence such repair or
restoration within ninety (90) days after such obligation shall accrue, Lessee
may at Lessee's option cancel and terminate this Lease by giving Lessor written

date of such notice.

     9.6 TERMINATION--ADVANCE PAYMENTS. Upon termination of this Lease pursuant
to this paragraph 9, an equitable adjustment shall be made concerning advance

10.  REAL PROPERTY TAXES.

     10.1 PAYMENT OF TAX INCREASE. Lessor shall pay the real property tax, as
defined in paragraph 10.3, applicable to the Industrial Center, provided,
however, that Lessee shall pay, in addition to rent, Lessee's Share (as defined
in paragraph 4.2(a)) of the amount, if any, by which real property taxes
applicable to the Premises increase over the fiscal real estate tax year
19___-19___. Such payment shall be made by Lessee within thirty (30) days after
receipt of Lessor's written statement setting forth the amount of such increase
and the computation thereof. If the term of this Lease shall not expire
concurrently with the expiration of the tax fiscal year, Lessee's liability for
increased taxes for the last partial lease year shall be prorated on an annual
basis.

     10.2 ADDITIONAL IMPROVEMENTS. Lessee shall not be responsible for paying
Lessee's Share of any increase in real property tax specified in the tax
assessor's records and work sheets as being caused by additional improvements
placed upon the Industrial Center by other lessees or by Lessor for the
exclusive enjoyment of such other lessees. Lessee shall, however, pay to Lessor
at the time that Operating Expenses are payable under paragraph 4.2(c) the
entirety of any increase in real property tax if assessed solely by reason of
additional improvements placed upon the Premises by Lessee or at Lessee's
request.

     10.3 DEFINITION OF "REAL PROPERTY TAX." As used herein, the term "real
property tax" shall include any form of real estate tax or assessment, general,
special, ordinary or extraordinary, and any license fee, commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed on the Industrial Center or any portion thereof by any
authority having the direct or indirect power to tax, including any city,
county, state or federal government, or any school, agricultural, sanitary,
fire, street, drainage or other improvement district thereof, as against any
legal or equitable interest of Lessor in the Industrial Center or in any portion
thereof, as against Lessor's right to rent or other income therefrom, and as
against Lessor's business of leasing the Industrial Center. The term "real
property tax" shall also include any tax, fee, levy, assessment or charge (i) in
substitution of, partially or totally, any tax, fee, levy, assessment or charge
hereinabove included within the definition of "real property tax," or (ii) the
nature of which was hereinbefore included within the definition of "real
property tax," or (iii) which is imposed for a service or right not charged
prior to June 1, 1978, or, if previously charged, has been increased since June
1, 1978, or (iv) which is imposed as a result of a transfer, either partial or
total, of Lessor's interest in the Industrial Center or which is added to a tax
or charge hereinbefore included within the definition of real property tax by
reason of such transfer, or (v) which is imposed by reason of this transaction,
any modifications or changes hereto, or any transfers hereof.

     10.4 JOINT ASSESSMENT. If the Industrial Center is not separately
assessed, Lessee's Share of the real property tax liability shall be an
equitable proportion of the real property taxes for all of the land and
improvements included within the tax parcel assessed, such proposition to be
determined by Lessor from the respective valuations assigned in the assessor's
work sheets or such other information as may be reasonably available. Lessor's
reasonable determination thereof, in good faith, shall be conclusive.

     10.5 PERSONAL PROPERTY TAXES.

         (a) Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere. When possible, Lessee
shall cause said trade fixtures, furnishings, equipment and all other personal
property to be assessed and billed separately from the real property of Lessor.

         (b) If any of Lessee's said personal property shall be assessed with
Lessor's real property, Lessee shall pay to Lessor the taxes attributable to
Lessee within ten (10) days after receipt of a written statement setting forth
the taxes applicable to Lessee's property.

11.  UTILITIES. Lessee shall pay for all water, gas, heat, light, power,
telephone and other utilities and services supplied to the Premises, together
with any taxes thereon. If any such services are not separately metered to the
Premises, Lessee shall pay at Lessor's option, either Lessee's Share or a
reasonable proportion to be determined by Lessor of all charges jointly metered
with other premises in the Building.

                                      -4-

12.  ASSIGNMENT AND SUBLETTING.

     12.1 LESSOR'S CONSENT REQUIRED. Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold. Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting without such consent shall be void, and shall constitute a breach of
this Lease without the need for notice to Lessee under paragraph 13.1.

     12.2 LESSEE AFFILIATE. Notwithstanding the provisions of paragraph 12.1
hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, to any corporation which controls, is controlled by or
is under common control with Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or entity which acquires
all the assets of Lessee as a going concern of the business that is being
conducted on the Premises, all of which are referred to as "Lessee Affiliate,"
provided that before such assignment shall be effective said assignee shall
assume, in full, the obligations of Lessee under this Lease. Any such assignment
shall not, in any way, affect or limit the liability of Lessee under the terms
of this Lease even if after such assignment or subletting the terms of this
Lease are materially changed or altered without the consent of Lessee, the
consent of whom shall not be necessary.

     12.3 TERMS AND CONDITIONS OF ASSIGNMENT. Regardless of Lessor's consent, no
assignment shall release Lessee of Lessee's obligations hereunder or alter the
primary liability of Lessee to pay the Base Rent and Lessee's Share of Operating
Expenses, and to perform all other obligations to be performed by Lessee
hereunder. Lessor may accept rent from any person other than Lessee pending
approval or disapproval of such assignment. Neither a delay in the approval or
disapproval of such assignment nor the acceptance of rent shall constitute a
waiver or estoppel or Lessor's right to exercise its remedies for the breach of
any of the terms or conditions of this paragraph 12 or this Lease. Consent to
one assignment shall not be deemed consent to any subsequent assignment. In the
event of default by any assignee of Lessee or any successor of Lessee, in the
performance of any of the terms hereof, Lessor may proceed directly against
Lessee without the necessity of exhausting remedies against said assignee.
Lessor may consent to subsequent assignments of this Lease or amendments or
modifications to this Lease with assignees of Lessee, without notifying Lessee,
or any successor of Lessee, and without obtaining its or their consent thereto
and such action shall not relieve Lessee of liability under this Lease.

     12.4 TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. Regardless of Lessor's
consent, the following terms and conditions shall apply to any subletting by
Lessee of all or any part of the Premises and shall be included in subleases.

         (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
hereafter made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease; provided, however, that until
a default shall occur in the performance of Lessee's obligations under this
Lease, Lessee may receive, collect and enjoy the rents accruing under such
sublease. Lessor shall not, by reason of this or any other assignment of such
sublease to Lessor nor by reason of the collection of the rents from a
sublessee, be deemed liable to the sublessee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under such
sublease. Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor stating that a default exists in
the performance of Lessee's obligations under this Lease, to pay to Lessor the
rents due and to become due under the sublease. Lessee agrees that such
sublessee shall have the right to rely upon any such statement and request from
Lessor, and that such sublessee shall pay such rents to Lessor without any
obligation or right to inquire as to whether such default exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against such sublessee or Lessor for any such rents
so paid by said sublessee to Lessor.

         (b) No sublease entered into by Lessee shall be effective unless and
until it has been approved in writing by Lessor. In entering into any sublease,
Lessee shall use only such form of sublease as is satisfactory to Lessor, and
once approved by Lessor, such sublease shall not be changed or modified without
Lessor's prior written consent. Any sublessee shall, by reason of entering into
a sublease under this Lease, be deemed, for the benefit of Lessor, to have
assumed and agreed to conform and comply with each and every obligation herein
to be performed by Lessee other than such obligations as are contrary to or
inconsistent with provisions contained in a sublease to which Lessor has
expressly consented in writing.

         (c) If Lessee's obligations under this Lease have been guaranteed by
third parties, then a sublease, and Lessor's consent thereto, shall not be
effective unless said guarantors give their written consent to such sublease and
the terms thereof.

         (d) The consent by Lessor to any subletting shall not release Lessee
from its obligations or alter the primary liability of Lessee to pay the rent
and perform and comply with all of the obligations of Lessee to be performed
under this Lease.

         (e) The consent by Lessor to any subletting shall not constitute a
consent to any subsequent subletting by Lessee or to any assignment or
subletting by the sublessee. However, Lessor may consent to subsequent
sublettings and assignments of the sublease or any amendments or modifications
thereto without notifying Lessee or anyone else liable on the Lease or sublease
and without obtaining their consent and such action shall not relieve such
persons from liability.

         (f) In the event of any default under this Lease, Lessor may proceed
directly against Lessee, any guarantors or any one else responsible for the
performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefor to
Lessor, or any security held by Lessor or Lessee.

         (g) In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of Lessee under such sublease from the time of
the exercise of said option to the termination of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to Lessee or for any other prior defaults of Lessee under
such sublease.

         (h) Each and every consent required of Lessee under a sublease shall
also require the consent of Lessor.

         (i) No sublessee shall further assign or sublet all or any part of the
Premises without Lessor's prior written consent.

         (j) Lessor's written consent to any subletting of the Premises by
Lessee shall not constitute an acknowledgment that no default then exists under
this Lease of the obligations to be performed by Lessee nor shall such consent
be deemed a waiver of any then existing default, except as may be otherwise
stated by Lessor at the time.

         (k) With respect to any subletting to which Lessor has consented,
Lessor agrees to deliver a copy of any notice of default by Lessee to the
sublessee. Such sublessee shall have the right to cure a default of Lessee
within ten (10) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset from
and against Lessee for any such defaults cured by the sublessee.

     12.5 ATTORNEY'S FEES. In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable attorney's fees incurred in connection
therewith, such attorney's fees not to exceed $350.00 for each such request.

13.  DEFAULT; REMEDIES.

     13.1 DEFAULT. The occurrence of any one or more of the following events
shall constitute a material default of this Lease by Lessee:

         (a) The vacating or abandonment of the Premises by Lessee.

         (b) The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due, where such
failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee. In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the notice required by
this subparagraph.

         (c) Except as otherwise provided in this Lease, the failure by Lessee
to observe or perform any of the covenants, conditions or provisions of this
Lease to be observed or performed by Lessee, other than described in paragraph
(b) above, where such failure shall continue for a period of thirty (30) days
after written notice thereof from Lessor to Lessee; provided, however, that if
the nature of Lessee's noncompliance is such that more than thirty (30) days are
reasonably required for its cure, then Lessee shall not be deemed to be in
default if Lessee commenced such cure within said thirty (30) day period and
thereafter diligently prosecutes such cure to completion. To the extent
permitted by law, such thirty (30) day notice shall constitute the sole and
exclusive notice required to be given to Lessee under applicable Unlawful
Detainer statutes.

         (d) (i) The making by Lessee of any general arrangement or general
assignment for the benefit of creditors; (ii) Lessee becomes a "debtor" as
defined in 11 U.S.C. section 101 or any successor statute thereto (unless, in
the case of a petition filed against Lessee, the same is dismissed within sixty
(60) days); (iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within thirty
(30) days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days. In the event that any provision of this paragraph 13.1(d) is contrary to
any applicable law, such provision shall be of no force or effect.

         (e) The discovery by Lessor that any financial statement given to
Lessor by Lessee, any assignee of Lessee, any subtenant of Lessee, any successor
in interest of Lessee or any guarantor of Lessee's obligation hereunder, was
materially false.

 13.2 REMEDIES. In the event of any such material default by Lessee, Lessor
may at any time thereafter, with or without notice or demand and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such default:

     (a) Terminate Lessee's right to possession of the Premises by any lawful
means, in which case this Lease and the term hereof shall terminate and Lessee
shall immediately surrender possession of the Premises to Lessor. In such event
Lessor shall be entitled to recover from Lessee all damages incurred by Lessor
by reason of Lessee's default including, but not limited to, the cost of
recovering possession of the Premises, expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorney's fees,
and any real estate commission actually paid; the worth at the time of award by
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to paragraph 15
applicable to the unexpired term of this Lease.

                                      -5-
<PAGE>   6
         (b) Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have vacated or abandoned
the Premises. In such event Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

         (c) Pursue and other remedy now or hereafter available to Lessor under
the laws or judicial decisions of the state wherein the Premises are located.
Unpaid installments of rent and other unpaid monetary obligations of Lessee
under the terms of this Lease shall bear interest from the date due at the
maximum rate then allowable by law.

     13.3 DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor fails
to perform obligations required by Lessor within a reasonable time, but in no
event late than thirty (30) days after written notice by Lessee to Lessor and to
the holder of any first mortgage or deed of trust covering the Premises whose
name and address shall have theretofore been furnished to Lessee in writing,
specifying wherein Lessor has failed to perform such obligation; provided,
however, that if the nature of Lessor's obligation is such that more than thirty
(30) days are required for performance then Lessor shall not be in default if
Lessor commences performance within such thirty (30) day period and thereafter
diligently prosecutes the same to completion.

     13.4 LATE CHARGES. Lessee hereby acknowledges that the late payment by
Lessee to Lessor Base Rent, Lessee's Share of Operating Expenses or other sums
due hereunder will cause Lessor to incur costs not contemplated by this Lease,
the exact amount of which will be extremely difficult to ascertain. Such costs
include, but are not limited to, processing and accounting charges, and late
charges which may be imposed on Lessor by the terms of any mortgage or trust
deed covering the Industrial Center. Accordingly, if any installment of Base
Rent, Operating Expenses, or any other sum due from Lessee shall not be received
by Lessor or Lessor's designee within ten (10) days after such amount shall be
due, then, without any requirement for notice to Lessee, Lessee shall pay to
Lessor a late charge equal to 6% of such overdue amount. The parties hereby
agree that such late charge shall in no event constitute a waiver of Lessee's
default with respect to such overdue amount, nor prevent Lessor from exercising
any of the other rights and remedies granted hereunder. In the event that a late
charge is payable hereunder, whether or not collected, for three (3) consecutive
installments of any of the aforesaid monetary obligations of Lessee, then Base
Rent shall automatically become due and payable quarterly in advance, rather
than monthly, notwithstanding paragraph 4.1 or any other provision of this Lease
to the contrary.

14.  CONDEMNATION. If the Premises or any portion thereof or the Industrial
Center are taken under the power of eminent domain, or sold under the threat of
the exercise of said power (all of which are herein called "condemnation"), this
Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs. If more than ten
percent of the floor area of the Premises, or more than twenty-five percent of
that portion of the Common Areas designated as parking for the Industrial Center
is taken by condemnation, Lessee may, at Lessee's option, to be exercised in
writing only within ten (10) days after Lessor shall have given Lessee written
notice of such taking (or in the absence of such notice, within ten (10) days
after the condemning authority shall have taken possession) terminate this Lease
as of the date the condemning authority takes such possession. If Lessee does
not terminate this Lease in accordance with the foregoing, this Lease shall
remain in full force and effect as to the portion of the Premises remaining,
except that the rent shall be reduced in the proportion that the floor area of
the Premises taken bears to the total floor area of the Premises. No reduction
of rent shall occur if the only area taken is that which does not have the
Premises located thereon. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution in value of the leasehold or for
the taking of the fee, or as severance damages; provided, however, that Lessee
shall be entitled to any award for loss of or damage to Lessee's trade fixtures
and removable personal property. In the event that this Lease is not terminated
by reason of such condemnation, Lessor shall to the extent of severance damages
received by Lessor in connection with such condemnation, repair any damage to
the Premises caused by such condemnation except to the extent that Lessee has
been reimbursed therefor by the condemning authority. Lessee shall pay any
amount in excess of such severance damages required to complete such repair.

15.  BROKER'S FEE.

     (a) Upon execution of this Lease by both parties, Lessor shall pay to
________________________________________________________________________________

________________________________________________ Licensed real estate broker(s),

a fee as set forth in a separate agreement between Lessor and said broker(s), or
in the event there is no separate agreement between Lessor and said broker(s),
the sum of $____ , for brokerage services rendered by said broker(s) to Lessor
in this transaction.

     (b) Lessor further agrees that if Lessee exercises any Option, as defined
in paragraph 39.1 of this Lease, which is granted to Lessee under this Lease, or
any subsequently granted option which is substantially similar to an Option
granted to Lessee under this Lease, or if Lessee acquires any rights to the
Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
Lessee been exercised, or if Lessee remains in possession of the Premises after
the expiration of the term of this Lease after having failed to exercise an
Option, or if said broker(s) are the procuring cause of any other lease or sale
entered into between the parties pertaining to the Premises and/or any adjacent
property in which Lessor has an interest, then as to any of said transactions,
Lessor shall pay said broker(s) a fee in accordance with the schedule of said
broker(s) in effect at the time of execution of this Lease.

     (c) Lessor agrees to pay said fee not only on behalf of Lessor but also on
behalf of any person, corporation, association, or other entity having an
ownership interest in said real property or any part thereof, when such fee is
due hereunder. Any transferee of Lessor's interests in this Lease, whether such
transfer is by agreement or by operation of law, shall be deemed to have assumed
Lessor's obligation under this paragraph 15. Said broker shall be a third party
beneficiary of the provisions of this paragraph 15.

16.  ESTOPPEL CERTIFICATE.

     (a) Each party (as "responding party") shall at any time upon not less than
ten (10) days' prior written notice from the other party ("requesting party")
execute, acknowledge and deliver to the requesting party a statement in writing
(i) certifying that this Lease is unmodified and in full force and effect (or,
if modified, stating the nature of such modification and certifying that this
Lease, as so modified, is in full force and effect) and the date to which the
rent and other charges are paid in advance, if any, and (ii) acknowledging that
there are not, to the responding party's knowledge, any uncured defaults on the
part of the requesting party, or specifying such defaults if any are claimed.
Any such statement may be conclusively relied upon by any prospective purchaser
or encumbrancer of the Premises or of the business of the requesting party.

     (b) At the requesting party's option, the failure to deliver such statement
within such time shall be a material default of this Lease by the party who is
to respond, without any further notice to such party, or it shall be conclusive
upon such party that (i) this Lease is in full force and effect, without
modification except as may be represented by the requesting party, (ii) there
are no uncured defaults in the requesting party's performance, and (iii) if
Lessor is the requesting party, not more than one month's rent has been paid in
advance.

     (c) If Lessor desires to finance, reliance, or sell the Industrial Center,
or any part thereof, Lessee hereby agrees to deliver to any lender or purchaser
designated by Lessor such financial statements of Lessee as may be reasonably
required by such lender or purchaser. Such statements shall include the past
three (3) years' financial statements of Lessee. All such financial statements
shall be received by Lessor and such lender or purchaser in confidence and shall
be used only for the purposes herein set forth.

17.  LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean only the
owner or owners, at the time in question, of the fee title or a lessee's
interest in a ground lease of the Industrial Center, and except as expressly
provided in paragraph 15, in the event of any transfer of such title or interest
Lessor herein named (and in case of any subsequent transfers then the grantor)
shall be relieved from and after the date of such transfer of all liability as
respects Lessor's obligations thereafter to be performed, provided that any
funds in the hands of Lessor or the then grantor at the time of such transfer,
in which Lessee has an interest, shall be delivered to the grantee. The
obligations contained in this Lease to be performed by Lessor shall, subject as
aforesaid, be binding on Lessor's successors and assigns, only during their
respective periods of ownership.

18.  SEVERABILITY. The invalidity of any provision of this Lease as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19.  INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law from the date due. Payment of such interest shall not
excuse or cure any default by Lessee under this Lease; provided, however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

20.  TIME OF ESSENCE. Time is of the essence with respect to the obligations to
be performed under this Lease.

21.  ADDITIONAL RENT. All monetary obligations of Lessee to Lessor under the
terms of this Lease, including but not limited to Lessee's Share of Operating
Expenses and insurance and tax expenses payable shall be deemed to be rent.

22.  INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS. This Lease contains all
agreements of the parties with respect to any matter mentioned herein. No prior
or contemporaneous agreement or understanding pertaining to any such matter
shall be effective. This Lease may be modified in writing only, signed by the
parties in interest at the time of the modification. Except as otherwise stated
in this Lease, Lessee hereby acknowledges that neither the real estate broker
listed in paragraph 15 hereof nor any cooperating broker on this transaction nor
the Lessor or any employee or agents of any of said persons has made any oral or
written warranties or representations to Lessee relative to the condition or use
by Lessee of the Premises or the Industrial Center and Lessee acknowledges that
Lessee assumes all responsibility regarding the Occupational Safety Health Act,
the legal use and adaptability of the Premises and the compliance thereof with
all applicable laws and regulations in effect during the term of this Lease
except as otherwise specifically stated in this Lease.

23.  NOTICES. Any notice required or permitted to be given hereunder shall be in
writing and may be given by personal delivery or by certified mail, and if given
personally or by mail, shall be deemed sufficiently given if addressed to Lessee
or to Lessor at the address noted below the signature of the respective parties,
as the case may be. Either party may by notice to the other specify a different
address for notice purposes except that upon Lessee's taking possession of the
Premises, the Premises shall constitute Lessee's address for notice purposes. A
copy of all notices required or permitted to be given to Lessor hereunder shall
be concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate by notice to Lessee.

                                      -6-
<PAGE>   7
24. WAIVERS. No waiver by Lessor or any provision hereof shall be deemed a
waiver of any other provision hereof or of any subsequent breach of Lessee of
the same or any other provision. Lessor's consent to, or approval of, any act
shall not be deemed to render unnecessary the obtaining of Lessor's consent to
or approval of any subsequent act by Lessee. The acceptance of rent hereunder by
Lessor shall not be a waiver of any preceding breach by Lessee of any provision
hereof, other than the failure of Lessee to pa the particular rent so accepted,
regardless of Lessor's knowledge of such preceding breach at the time of
acceptance of such rent.

25. RECORDING. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a "short form" memorandum of this
Lease for recording purposes.

26. HOLDING OVER. If Lessee, with Lessor's consent, remains in possession of
the Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, but all Options, if any, granted
under the terms of this Lease shall be deemed terminated and be of no further
affect during said month to month tenancy.

27. CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28.  COVENANTS AND CONDITIONS. each provision of this Lease performable by
Lessee shall be deemed both a covenant and a condition.

29.  BINDING EFFECT; CHOICE OF LAW. Subject to any provisions hereof restricting
assignment or subletting by Lessee and subject to the provisions of paragraph
17, this Lease shall bind the parties, their personal representatives,
successors and assigns. This Lease shall be governed by the laws of the State
where the Industrial Center is located and any litigation concerning this Lease
between the parties hereto shall be initiated in the county in which the
Industrial Center is located.

30.  SUBORDINATION.

     (a) This Lease, and any Option granted hereby, at Lessor's option, shall be
subordinate to any ground lease, mortgage, deed of trust, or any other
hypothecation or security now or hereafter placed upon the Industrial Center and
to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extension thereof.
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not be disturbed if Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provision of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. If any
mortgagee, trustee or ground lessor shall elect to have this Lease and any
Options granted hereby prior to the lien of its mortgage, deed of trust or
ground lease, and shall give written notice thereof to Lessee, this Lease and
such Options shall be deemed prior to such mortgage, deed of trust or ground
lease, whether this Lease or such Options are denied prior or subsequent to the
date of said mortgage, deed of trust or ground lease or the date of recording
thereof.

     (b) Lessee agrees to execute any documents required to effectuate an
allotment, a subordination or to make this Lease or any Option granted herein
prior to the lien of any mortgage, deed of trust or ground lease, as the case
may be. Lessee's failure to execute such documents within ten (10) days after
written demand shall constitute a material default by Lessee hereunder without
further notice to Lessee or, at Lessor's option, Lessor shall execute such
documents on behalf of Lessee as Lessee's attorney-in-fact. Lessee does hereby
make, constitute and irrevocably appoint Lessor as Lessee's attorney-in-fact and
in Lessee's name, place and stead, to execute such documents in accordance with
this paragraph 30(b).

31.  ATTORNEY'S FEES. If either party or the broker(s) named herein bring an
action to enforce the terms hereof or declare rights hereunder, the prevailing
party in any such action, on trial or appeal, shall be entitled to his
reasonable attorney's fees to be paid by the losing party as fixed by the court.
The provisions of this paragraph shall inure to the benefit of the broker named
herein who seeks to enforce a right hereunder.

32.  LESSOR'S ACCESS. Lessor and Lessor's agents shall have the right to enter
the Premises at reasonable times for the purpose of inspecting the same, showing
the same to prospective purchasers, lenders or lessees, and making such
alterations, repairs, improvements or additions to the Premises or to the
Industrial Center as Lessor may deem necessary or desirable. Lessor may at any
time place on or about the Premises or the Building any ordinary "For Sale"
signs and Lessor may at any time during the last 120 days of the term hereof
place on or about the Premises any ordinary "For Lease" signs. All activities of
Lessor pursuant to this paragraph shall be without abatement of rent, nor shall
Lessor have any liability to Lessee for the same.

33.  AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises or the Common Areas
without first having obtained Lessor's prior written consent. Notwithstanding
anything to the contrary to this Lease, Lessor shall not be obligated to
exercise any standard of reasonableness in determining whether to grant such
consent.

34.  SIGNS. Lessee shall not place any sign upon the Premises or the Industrial
Center without Lessor's prior written consent. Under no circumstances shall
Lessee place a sign on any roof of the Industrial Center.

35.  MERGER. The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing
subtenancies or may, at the option of Lessor, operate as an assignment to Lessor
of any or all of such subtenancies.

36.  CONSENTS. Except for paragraph 33 hereof, wherever in this Lease the
consent of one party is required to an act of the other party such consent shall
not be unreasonably withheld or delayed.

37.  GUARANTOR. In the event that there is a guarantor of this Lease, said
guarantor shall have the same obligations as Lessee under this Lease.

38.  QUIET POSSESSION. Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease. The Individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the
Industrial Center.

39.  OPTIONS.

Lessor or the right of first offer to purchase other property of Lessor.

     39.2 OPTIONS PERSONAL. Each Option granted to Lessor in this Lease is
personal to the original Lessee and may be exercised only by the original Lessee
while occupying the Premises who does so without the intent of thereafter
assigning this Lease or subletting the Premises or any portion thereof, and may
not be exercised or be assigned, voluntarily or involuntarily, by or to any
person or entity other than Lessee, provided, however, that an Option may be
exercised by or assigned to any Lessee Affiliate as defined in paragraph 12.2 of
this Lease. The Options, if any, herein granted to Lessee are not assignable
separate and apart from this Lease, nor may any Option be separated from the
this Lease in any manner, either by reservation or otherwise.

     39.3 MULTIPLE OPTIONS. In the event that Lessee has any multiple options to
extend or renew this Lease a [illegible] option cannot be exercised unless the
prior option to extend or renew this Lease has been so exercised.

     39.4 EFFECT OF DEFAULT ON OPTIONS.

         (a) Lessee shall have no right to exercise an Option, notwithstanding
any provision in the grant of Option to the contrary, (i) during the time
commencing from the date Lessor gives to Lessee a notice of default pursuant to
paragraph 13.1(b) or 13.1(c) and continuing until the noncompliance alleged in
said notice of default is cured, or (ii) during the period of time commencing on
the date after a monetary obligation to Lessor is due from Lessee and unpaid
(without any necessity for notice thereof to Lessee) and continuing until the
obligation is paid, or (iii) at any time after an event of default described in
paragraphs 13.1(a), 13.1(d), or 13.1(e) (without any necessity of Lessor to give
notice of such default to Lessee), or (iv) in the event that Lessor has given to
Lessee three or more notices of default under paragraph 13.1(b) or paragraph
13.1(c), whether or not the defaults are cured, during the 12 month period of
time immediately prior to the time that Lessee attempts to exercise the subject
Option.

         (b) The period time within which an Option may be exercised shall not
be extended or enlarged by reason of Lessee's inability to exercise an Option
because of the provisions of paragraph 39.4(a).

         (c) All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of

13.1(b), or paragraph 13.1(c), whether or not the defaults are cured.

the benefit of the Premises or the Industrial Center. Lessee assumes all
responsibility for the protection of Lessee, its agents, and invitees and the
property of Lessee and of Lessee's agents and invitees from acts of third
parties. Nothing herein contained shall prevent Lessor, at Lessor's sole option,
from providing security protection for the Industrial Center or any part
thereof, in which event the cost thereof shall be included within the definition
of Operating Expenses, as set forth in paragraph 4.2(b).

such easements, rights and dedications that Lessor deems necessary or desirable,
and to cause the recordation of Parcel Maps and restrictions, so long as such
easements, rights, dedications, Maps and restrictions do not unreasonably
interfere with the use of the Premises by Lessee. Lessee shall sign any of the
aforementioned documents upon request of Lessor and failure to do so shall
constitute a material default of this Lease by Lessee without the need for
further notice to Lessee.

42.  PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise as to any
amount or sum of money to be paid by one party to the other under the provisions
hereof, the party against whom the obligation to pay the money is asserted shall
have the right to make payment, under protest, and such payment shall not be
regarded as a voluntary payment, and there shall survive the right on the part
of said party to institute suit for recovery of such sum. If it shall be
adjudged that there was no legal obligation on the part of said party to pay
such sum or any part thereof, said party shall be entitled to recover such sum
or so much thereof as it was not legally required to pay under the provisions of
this Lease.

43.  AUTHORITY. If Lessee is a corporation, trust, or general or limited
partnership, each individual executing this Lease on behalf of such entity
represents and warrants that he or she is duly authorized to execute and deliver
this Lease on behalf of said entity. If Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after execution of this
Lease, deliver to Lessor evidence of such authority satisfactory to Lessor.

44.  CONFLICT. Any conflict between the printed provisions of this Lease and the
typewritten or handwritten provisions, if any, shall be controlled by the
typewritten or handwritten provisions.

45.  OFFER. Preparation of this Lease by Lessor or Lessor's agent and submission
of same to Lessee shall not be deemed an offer to lease. This Lease shall become
binding upon Lessor and Lessee only when fully executed by Lessor and Lessee.

47 through _______ which constitute a part of this Lease.

                  a certificate, certified by Purchaser's independent
                  accountants, setting forth the Sales for 1998 and 1999 (the
                  "Sales Certificate").

                      (iii) Within thirty days after receipt of the Sales
                  Certificate, Seller shall notify Purchaser if it disagrees
                  with the calculation of Sales. If such notice is not given (or
                  at such time as Seller provides written notice to Purchaser
                  that it has no objection to such calculation), the Sales
                  Certificate provided by Purchase will be final and binding for
                  all purposes. If the parties are unable to resolve their
                  differences within 60 days of the receipt by Seller of the

                  purposes. Seller and Purchaser shall each pay one-half of the

                  by Purchaser of written notice from Seller that it has no
                  objection to the calculation of the Sales pursuant to
                  Subsection 2(b)(ii) hereof, (B) the expiration of the 30-day
                  period for giving notice of disagreement with such

                  of any dispute pursuant to Section 2.2(b)(iii), Purchaser will
                  deliver to Seller (or its shareholders upon a liquidation of
                  Seller) properly prepared certificates for the shares of
                  Common Stock deliverable under this Subsection 2.2(b). All
                  shares of Common Stock to be received by Seller (or its

                  2.2 are referred to as the "Shares."

constitute defaults by Seller, and no penalties have been incurred nor are
amendments pending, with respect to the Commitments, except as described in
Schedule 3.10. The Commitments are in full force and effect and are valid and
enforceable obligations of the parties thereto in accordance with their
respective terms, and no defenses, off-sets or counterclaims have been asserted
or, to the best knowledge of Seller, may be made by any party thereto, nor has
Seller waived any rights thereunder, except as described in Schedule 3.10.
Seller has not received notice of any default with respect to any Commitment.
Seller has not received notice of any plan or intention of any other party to
any Commitment to exercise any right to cancel or terminate any Commitment or
agreement, and Seller knows of no fact that would justify the exercise of such a
right.

         SECTION 3.11. PATENTS, TRADE-MARKS, SERVICE MARKS, COPYRIGHTS AND
TECHNOLOGY.

         (a) OWNERSHIP. Seller owns or possesses the right to use, all
Technology, patents, trade-marks, service marks and copyrights, if any,
necessary to conduct its business, or possesses adequate licenses or other
rights, if any, therefor, without conflict with the rights of others. Set forth
in Schedule 3.11 is a true and correct description of all (i) Technology,
trade-marks, trade-names, service marks and other trade designations, including
common law rights, registrations and applications therefor, and all patents,
copyrights and applications currently owned, pending, or


                                       6
<PAGE>   7


applied for, in whole or in part, by Seller with respect to the Assets and
Seller's business or Technology, and all licenses, royalties, assignments and
other similar agreements relating to the foregoing to which Seller is a party
(including expiration date if applicable); and (ii) all agreements relating to
Technology, know-how or processes that Seller is licensed or authorized to use
by others, or which it licenses or authorizes others to use ("Proprietary
Rights").

         (b) CONFLICTING RIGHTS OF THIRD PARTIES. To the best of Seller's
knowledge after due inquiry, Seller has the sole and exclusive right to use the
Proprietary Rights without infringing or violating the rights of any third
parties. No consent of third parties will be required for the transfer thereof
to Purchaser or the use thereof by Purchaser upon consummation of the
transactions contemplated hereby and the Proprietary Rights are freely
transferable. No claim has been asserted by any person to the ownership of or
right to use any Proprietary Right or challenging or questioning the validity or
effectiveness of any license or agreement constituting a part of any Proprietary
Right, and Seller knows of no valid basis for any such claim. Each of the
Proprietary Rights is valid and subsisting, has not been canceled, abandoned or
otherwise terminated and, if applicable, has been duly issued or filed.

         (c) CLAIMS OF OTHER PERSONS. Seller has no knowledge of any claim that,
or inquiry as to whether, any product, activity or operation of Seller, use of
Proprietary Rights of Seller or the use of the Technology infringes upon or
involves, or has resulted in the infringement of, any proprietary right of any
other person, corporation or other entity; and no proceedings have been
instituted, are pending or, to Seller's knowledge, are threatened that challenge
the rights of Seller with respect thereto. Seller has not given and is not bound
by any agreement of indemnification for any Proprietary Right as to the
Technology or any property manufactured, used or sold by Seller.

         SECTION 3.12. TRADE SECRETS AND CUSTOMER LISTS. To the best of Seller's
knowledge after due inquiry, Seller has the right to use, free and clear of any
claims or rights of others all trade secrets, customer lists and proprietary
information required for the marketing of all merchandise and services formerly
or presently sold or marketed by Seller. To the best of Seller's knowledge after
due inquiry, Seller is not using or in any way making use of any confidential
information or trade secrets of any third party, including without limitation
any past or present employee of Seller.

         SECTION 3.13. COMPLIANCE WITH LAWS. Seller has complied with all laws,
regulations and licensing requirements and has filed with the proper authorities
all necessary statements and reports. There are no existing violations by Seller
of any federal, state or local law or regulation that would affect the property
or business of Seller. Seller possesses all necessary licenses, franchises,
permits and governmental authorizations to conduct its business as now
conducted, all of which are listed in Schedule 3.13.

         SECTION 3.14. FINDER'S FEE. Neither Seller nor any Shareholder has
incurred any obligation for any finder's, broker's or agent's fee in connection
with the transactions contemplated hereby.

<PAGE>   8


         SECTION 3.15. LITIGATION. There are no legal actions or administrative
proceedings or investigations instituted, or to the best knowledge of Seller and
the Shareholders threatened, against or affecting, or to Seller's knowledge,
that would affect, Seller, any of the Assets, or the business of Seller. Seller
is not (i) subject to any continuing court or administrative order, writ,
injunction or decree applicable specifically to Seller or to its business,
assets, operations or employees or (ii) in default with respect to any such
order, writ, injunction or decree.

         SECTION 3.16. ENVIRONMENTAL MATTERS. Neither Seller nor any of the
Assets are currently in violation of, or subject to any existing, pending or
threatened investigation or inquiry by any governmental authority or to any
remedial obligations under, any laws or regulations pertaining to health or the
environment (hereinafter sometimes collectively called "Environmental Laws"),
and this representation and warranty would continue to be true and correct
following disclosure to the applicable governmental authorities of all relevant
facts, conditions and circumstances, if any, pertaining to the Assets. To the
best knowledge of Seller and the Shareholders, the Assets have never been used
in a manner that would be in violation of any of the Environmental Laws.

         SECTION 3.17. THE SHARES. Seller acknowledges that it has been afforded
an opportunity to question the officers and directors of Purchaser concerning
Purchaser and that Seller has been provided with all information concerning
Purchaser which Seller has requested. Seller recognizes the speculative nature
of an investment in the Shares, and that such an investment involves a high
degree of risk. Seller acknowledges that the Shares have not been registered
under the Securities Act of 1933, as amended (the "Act"), or the securities laws
of any state and is being offered and sold in reliance upon certain exemptions
from registration, and accordingly the Shares may not be resold unless
registered under the Act and applicable state securities laws or unless an
exemption from such registration is available, and that Purchaser will (i) cause
a legend to be placed on any share certificate which may be issued stating that
the shares of Common Stock represented by such certificate may not be
transferred unless registered under the Act and applicable state securities laws
or unless Seller obtains an opinion of counsel satisfactory to Purchaser that
such registration is not required and (ii) make appropriate notations in
Purchaser's records to prevent the transfer of any Common Stock in violation of
such laws. Seller will not offer to sell or otherwise transfer the Shares, or
any part thereof or interest therein, except in compliance with applicable
securities laws. Notwithstanding anything in this Section 3.17 to the contrary,
Purchaser acknowledges that the Shareholders may cause the Seller to be
liquidated and the shares to be distributed to the shareholders of Seller in
connection with such liquidation (the "Liquidating Distribution"). Purchaser
acknowledges that the Liquidating Distribution will not constitute a violation
of the Act or any applicable state securities laws.

         SECTION 3.18. TAXES. Seller has duly and timely filed with the
appropriate governmental agencies all income, excise, corporate, franchise,
property, sales, use, payroll, withholding and other tax returns (including
information returns) and reports required to be filed by the United States or
any state or any political subdivision thereof or any foreign jurisdiction. All
such tax returns or reports are complete and accurate and properly reflect the
taxes of Seller for the periods covered thereby. Seller has paid or accrued all
taxes, penalties and interest that have become due with


                                       8
<PAGE>   9


respect to any returns that it has filed and any assessments of which it is
aware. Seller is not delinquent in the payment of any tax, assessment or
governmental charge. No tax deficiency or delinquency has been asserted against
Seller. There is no unpaid assessment, proposal for additional taxes, deficiency
or delinquency in the payment of any of the taxes of Seller that could be
asserted by any taxing authority. There is no taxing authority audit of Seller
pending or threatened, and the results of any completed audits are properly
reflected in the Seller Financial Statements. Seller has not violated any
federal, state, local or foreign tax law. Seller has not granted an extension to
any taxing authority of the limitation period during which any tax liability may
be assessed or collected. All monies required to be withheld by Seller and paid
to governmental agencies for all income, social security, unemployment
insurance, sales, excise, use, and other taxes have been (i) collected or
withheld and either paid to the respective governmental agencies or set aside in
accounts for such purpose or (ii) properly reflected in the Seller Financial
Statements. The foregoing representations and warranties contained in this
Section 3.18 shall not be deemed to be breached or violated to the extent such
breach or violation could not result in the imposition of a lien on the Assets
or the imposition of any liability on Purchaser.

         SECTION 3.19. UNIVERSAL DOCK PRODUCT. To the best of Seller's
knowledge, the items set forth in Exhibits 1 and 2 to Exhibit A to the Amendment
(as defined in Section 5.1 (g) below) are the only material items which need to
be completed on Seller's current universal dock.

this Section 7.3); (b) the failure of Purchaser to pay, perform and discharge
when due any of the Assumed Liabilities; (c) any liability arising out of or
relating to the operation of the business transferred hereunder or the ownership
or use of the Assets after the Closing Date to the extent such liability were
incurred or the events giving rise to such liabilities occurred after the
Closing Date; provided, however, that no claim shall be made for indemnification
under this Section 7.3 until, and such claims may be made only to the extent
that, the dollar amount of all such Damages shall exceed in the aggregate of
$10,000; provided, further, however, the aggregate liability of Purchaser for
Damages shall not exceed $300,000.

         SECTION 7.4. WAIVER. No waiver by any party of any default or breach
by another party of any representation, warranty, covenant or condition
contained in this Agreement, any exhibit or any document, instrument or
certificate contemplated hereby shall be deemed to be a waiver of any


                                       15
<PAGE>   16


subsequent default or breach by such party of the same or any other
representation, warranty, covenant or condition. No act, delay, omission or
course of dealing on the part of any party in exercising any right, power or
remedy under this Agreement or at law or in equity shall operate as a waiver
thereof or otherwise prejudice any of such party's rights, powers and remedies.
All remedies, whether at law or in equity, shall be cumulative and the election
of any one or more shall not constitute a waiver of the right to pursue other
available remedies.

         SECTION 7.5. REMEDIES NOT EXCLUSIVE. Subject to the provisions of
Section 7.6, the remedies provided in this Article shall not be exclusive of any
other rights or remedies available to one party against the other, either at law
or in equity.

         SECTION 7.6. OFFSET. Any and all amounts owing or to be paid by
Purchaser to Seller or a Shareholder of Seller (including, without limitation,
any Assumed Liability, including, without limitation, the amounts owed by Seller
to Mykola Moroz pursuant to that Promissory Note, a copy of which is attached
hereto as Schedule 7.6 (the "Note"); provided, however, that any breach by Moroz
of Article VIII hereof shall not be subject to offset against the Note.),
hereunder or otherwise, shall be subject to offset and reduction
dollar-for-dollar by any amounts that may be owing at any time by Seller to
Purchaser in respect of any failure or breach of any representation, warranty or
covenant of Seller under or in connection with this Agreement or any other
agreement with Purchaser or any transaction contemplated hereby or thereby, as
reasonably determined by Purchaser. If Purchaser determines that such offset is
appropriate, notice shall be given to Seller of such determination at least 10
days prior to the due date of the payment to be reduced. If Seller objects in
writing to any such offset within such ten (10) day period, then Purchaser and
Seller shall submit such matter to final and binding arbitration in Wilmington,
Delaware, in accordance with the Commercial Arbitration Rules of the American
Arbitration Association (the "AAA"). During the pendency of any offset action
hereunder (including any such arbitration action), Purchaser will make payments
under the Note into escrow with the AAA. If the conditions upon which the
reduction is based are cured by Seller prior to such due date, as determined by
Purchaser, the amount of such payment shall not be so reduced.

         SECTION 7.7. COSTS, EXPENSES AND LEGAL FEES. Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including attorneys' fees), except that each party
hereto agrees to pay the costs and expenses (including reasonable attorneys'
fees and expenses) incurred by the other parties in successfully (a) enforcing
any of the terms of this Agreement; (b) proving that another party breached any
of the terms of this Agreement or (c) defending against any suit or claim by a
party brought to enforce any terms of this Agreement.

                                 NONCOMPETITION

         SECTION 8.1. MOROZ PROHIBITED ACTIVITIES. In consideration for
Purchaser's execution and delivery of this Agreement, and other good and
valuable consideration, Moroz hereby agrees that for a period of five (5) years
following the Closing Date, he shall not knowingly, directly or indirectly, for
himself or on behalf of any other corporation, person, firm, partnership,
association, or any other entity (whether as an individual, agent, servant,
employee, employer, officer, director, shareholder, investor, principal,
consultant or in any other capacity):

         (a) engage or participate in any business which engages in any business
which engages in any business relating to the design, manufacture or sale of
port replicators and docking stations for portable computers in competition with
the business of Purchaser and its affiliates (the "Purchaser Group") in the
United States of America or any other country where the Purchaser Group conducts
business during such five-year period; provided, however, that this provision
shall not prohibit Moroz from purchasing or holding an aggregate equity interest
of up to 1%, so long as Moroz does not purchase or hold an aggregate equity
interest of more than 5%, in any business in competition with the Purchaser
Group;

         (b) induce or attempt to influence any employee, agent or consultant of
the Purchaser Group to terminate his employment or relationship with Purchaser
Group, or to hire, retain or utilize any person who is an employee, agent or
consultant of the Purchaser Group, or was an employee, agent or consultant of
the Purchaser Group during such five-year period, whether or not so induced or
influenced, except that any such employee may be hired or retained with
Purchaser's prior written consent; or

         (c) assist or finance any person or entity which competes (as defined
in subsection (a) hereof) with the Purchaser Group.

         SECTION 8.2. MYKOLA MOROZ PROHIBITED ACTIVITIES. In consideration
for Purchaser's execution and delivery of this Agreement, and other good and
valuable consideration, Mykola Moroz hereby agrees that for a period of five (5)
years following the Closing Date, he shall not knowingly, directly or
indirectly, for himself or on behalf of any other corporation, person, firm,
partnership, association, or any other entity (whether as an individual, agent,
servant, employee, employer, officer, director, shareholder, investor,
principal, consultant or in any other capacity):

         (a) engage or participate in any business which engages in any business
relating to the design, manufacture or sale of port replicators and docking
stations for portable computers in competition with the business of the
Purchaser Group and its affiliates in the United States of America or any other
country where the Purchaser Group conducts business during such five-year
period; provided, however, that this provision shall not prohibit Mike Moroz
from purchasing or holding an aggregate equity interest of up to 1%, so long as
Mike Moroz does not purchase or hold


                                       17
<PAGE>   18


an aggregate equity interest of more than 5%, in any business in competition
with the Purchaser Group; or

         (b) induce or attempt to influence any employee, agent or consultant of
the Purchaser Group to terminate his employment or relationship with the
Purchaser Group, or to hire, retain or utilize any person who is an employee,
agent or consultant of the Purchaser Group, or was an employee, agent or
consultant of the Purchaser Group during such five-year period, whether or not
so induced or influenced, except that any such employee, agent or consultant may
be hired or retained with Purchaser's prior written consent.

         SECTION 8.3. DAMAGES. Because of the difficulty of measuring
economic losses to the Purchaser as a result of the breach of the foregoing
covenant, and because of the immediate and irreparable damage that would be
caused to Purchaser for which it would have no other adequate remedy, each
Shareholder agrees that, in the event of a breach by such Shareholder of the
foregoing covenant, the covenant may be enforced by Purchaser by injunctions and
restraining orders.

         SECTION 8.4. REASONABLE RESTRAINT. It is agreed by the parties that
the foregoing covenants in this Article VIII impose a reasonable restraint on
each Shareholder in light of the activities and business of the Company on the
date of the execution of this Agreement and the future plans of the Company and
Purchaser. Each Shareholder hereby agrees that this covenant is a material and
substantial part of this transaction.

         SECTION 8.5. SEVERABILITY; REFORMATION. The covenants in this
Article VIII are severable and separate, and the unenforceability of any
specific covenant shall not affect the provisions of any other covenant.
Moreover, in the event any court of competent jurisdiction shall determine that
the scope, time or territorial restrictions set forth are unreasonable, then it
is the intention of the parties that such restrictions be enforced to the
fullest extent that the court deems reasonable, and the Agreement shall thereby
be reformed.


                                   ARTICLE IX
                                  MISCELLANEOUS

remedies hereunder or thereunder.

Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

         SECTION 9.6. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS (BUT NOT THE RULES GOVERNING
CONFLICTS OF LAWS) OF THE STATE OF DELAWARE.

                                 PROMISSORY NOTE


$400,000                     Minneapolis, Minnesota                 July 3, 1997


         FOR VALUE RECEIVED, the undersigned, Miram International, Inc., a
Minnesota corporation ("Maker"), promises to pay to Mykola Moroz ("Payee"), the
sum of Four Hundred Thousand and No/100 Dollars ($400,000), or such other amount
as may be outstanding, together with interest on the unpaid principal balance
from day to day remaining at the rate of eight percent (8%) per annum. Interest
shall accrue on any matured, unpaid amounts at the rate of ten percent (10%) per
annum.

         Principal of and interest on this Note shall be due and payable in
eight (8) equal quarterly installments of $54,603.92, on January 1, April 1,
July 1 and October 1, commencing on October 1, 1997. Notwithstanding the
foregoing, this Note shall be due and payable in full on the consummation of an
initial public offering by Maker of its common stock. Maker shall have the right
to prepay this Note at any time, in whole or in part, without premium or
penalty.

         The entire unpaid principal balance of, and all accrued interest on,
this Note shall immediately become due and payable at the option of the holder
hereof upon the occurrence of any of the following events ("Events of Default"):

                  (a) The failure or refusal of Maker to make any payment of
         this Note when due, and if such failure or refusal is not cured within
         five (5) days after receipt by Maker of written notice from Payee of
         such failure or refusal;

                  (b) The failure or refusal of Maker to punctually and properly
         perform, observe and comply in all material respects with each
         covenant, agreement or condition contained herein, and the breach of
         such covenant, agreement or condition is not cured to Payee's
         satisfaction within thirty (30) days after Maker's receipt of notice of
         such breach from Payee.

                  (c) Maker shall (i) execute an assignment for the benefit of
         creditors, (ii) admit in writing its inability, or otherwise, fail, to
         pay its debts generally as they become due, or (iii) suffer the
         appointment of a receiver, trustee, custodian or similar fiduciary; or

                  (d) Any petition for an order for relief shall be filed by or
         against Maker under the Bankruptcy Code (if against Maker, the
         continuation of such proceeding for more than thirty (30) days).

If an Event of Default shall occur, the holder of this Note may proceed to
protect and enforce any and all rights it may have, whether by contract or law.
In the event that any required payment of principal and/or interest hereunder is
not made within five (5) days after the date when due, Maker shall pay to Payee
a late payment charge equal to five percent (5%) of the amount of the


<PAGE>   2


overdue payment, for the purpose of reimbursing Payee for a portion of the
expense incident to handling the overdue payment.

         Time is of the essence hereof. If an Event of Default occurs, then the
entire unpaid principal balance, with all accrued interest thereon, shall, at
the option of Payee, become immediately due and payable without notice, demand
or presentment for payment, and without notice of intention to accelerate or of
acceleration.

         Maker, and each surety, endorser, guarantor, and other party ever
liable for the payment of any sum of money payable on this Note jointly and
severally at all times waive presentment, protest, notice of nonpayment, notice
of intention to accelerate and of acceleration, notice of protest and nonpayment
or dishonor, notice of intent to demand, diligence in collecting, and grace, and
consent to all extensions without notice for any period or periods of time and
partial payments before or after maturity, without prejudice to the holder.

         THIS NOTE IS BEING EXECUTED AND DELIVERED IN THE STATE OF MINNESOTA,
AND THE LAWS OF SUCH STATE SHALL GOVERN THE CONSTRUCTION VALIDITY, ENFORCEMENT
AND INTERPRETATION HEREOF, EXCEPT TO THE EXTENT FEDERAL LAWS OTHERWISE GOVERN
THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND LIMITATION HEREOF.

         All of the covenants, stipulations, promises and agreements contained
in this Note by or on behalf of Maker shall bind its successors and assigns,
whether so expressed or not.

         Regardless of any provision contained herein, or in any document
executed in connection herewith, Payee shall never be entitled to receive,
collect, or apply, as interest on the indebtedness evidenced hereby, any amount
in excess of the highest lawful interest rate permitted under applicable law
(the "Highest Lawful Rate"), and in the event Payee ever receives, collects, or
applies, as interest, any such excess, such amount which would be excessive
interest shall be deemed a partial prepayment of principal and treated hereunder
as such; and if, the principal hereof is paid in full, any remaining excess
shall be refunded to Maker. In determining whether or not the interest paid or
payable, under any specific contingency, exceeds the Highest Lawful Rate, Maker
and Payee shall, to the maximum extent permitted under applicable law, (a)
characterize any nonprincipal payment as an expense, fee, or premium rather than
as interest, (b) exclude voluntary prepayments and the effects thereof, and (c)
prorate, allocate, and spread, the total amount of interest throughout the
entire contemplated term hereof, provided, that if the principal balance hereof
is paid and performed in full prior to the end of the full contemplated term
hereof, and if the interest received for the actual period of existence thereof
exceeds the Highest Lawful Rate, Payee shall either apply or refund to Maker the
amount of such excess as herein provided, and in such event, Payee shall not be
subject to any penalties provided by any laws for contracting for, charging, or
receiving interest in excess of the Highest Lawful Rate.

         Maker agrees to reimburse Payee for all expenses paid or incurred by
Payee (including fees and expenses of legal counsel) in connection with the
collection and enforcement of the Note.

         PAYEE ACKNOWLEDGES THAT THIS NOTE IS NON-NEGOTIABLE.

         IN WITNESS WHEREOF, the undersigned has executed this Note as of the
day and year first above written.

     3. Administration.

     (a) Authority of the Committee. The Plan shall be administered by the
Committee. The Committee shall have full and final authority to take the
following actions, in each case subject to and consistent with the provisions of
the Plan and applicable law:

        (i) to select persons to whom Awards may be granted;

        (ii) to determine the type or types of Awards to be granted to each such
     person;

        (iii) to determine the number of Awards to be granted, the number of
     shares of Stock to which an Award will relate, the terms and conditions of
     any Award granted under the Plan (including, but not limited to, any
     exercise price, grant price or purchase price, any restriction or
     condition, any schedule for lapse of restrictions or conditions relating to
     transferability or forfeiture, exercisability or settlement of an Award,
     and waivers or accelerations thereof, performance conditions relating to an
     Award (including performance conditions relating to Awards not intended to
     be governed by Section 7(e) and waivers and modifications thereof), based
     in each case on such considerations as the Committee shall determine), and
     all other matters to be determined in connection with an Award;

        (iv) to determine whether, to what extent and under what circumstances
     an Award may be settled, or the exercise price of an Award may be paid, in
     cash, Stock, other Awards, or other property, or an Award may be cancelled,
     forfeited, or surrendered;

        (v) to determine whether, to what extent and under what circumstances
     cash, Stock, other Awards or other property payable with respect to an
     Award will be deferred either automatically, at the election of the
     Committee or at the election of the Participant;

        (vi) to prescribe the form of each Award Agreement, which need not be
     identical for each Participant;

        (vii) to adopt, amend, suspend, waive and rescind such rules and
     regulations and appoint such agents as the Committee may deem necessary or
     advisable to administer the Plan;

        (viii) to correct any defect or supply any omission or reconcile any
     inconsistency in the Plan and to construe and interpret the Plan and any
     Award, rules and regulations, Award Agreement or other instrument
     hereunder; and

        (ix) to make all other decisions and determinations as may be required
     under the terms of the Plan or as the Committee may deem necessary or
     advisable for the administration of the Plan.

                                       3
<PAGE>   5

     (b) Manner of Exercise of Committee Authority. Unless authority is
specifically reserved to the Board under the terms of the Plan, the Company's
Certificate of Incorporation or Bylaws, or applicable law, the Committee shall
have sole discretion in exercising authority under the Plan. Any action of the
Committee with respect to the Plan shall be final, conclusive and binding on all
persons, including the Company, subsidiaries of the Company, Participants, any
person claiming any rights under the Plan from or through any Participant and
stockholders, except to the extent the Committee may subsequently modify, or
take further action not consistent with, its prior action. If not specified in
the Plan, the time at which the Committee must or may make any determination
shall be determined by the Committee, and any such determination may thereafter
be modified by the Committee (subject to Section 8(e)). The express grant of any
specific power to the Committee, and the taking of any action by the Committee,
shall not be construed as limiting any power or authority of the Committee. The
Committee may delegate to officers or managers of the Company or any subsidiary
of the Company the authority, subject to such terms as the Committee shall
determine, to perform administrative functions and, with respect to Participants
not subject to Section 16 of the Exchange Act, to perform such other functions
as the Committee may determine, to the extent permitted under Rule 16b-3, if
applicable, and other applicable law.

     (c) Limitation of Liability. Each member of the Committee shall be entitled
to, in good faith, rely or act upon any report or other information furnished to
him by any officer or other Employee of the Company or any subsidiary, the
Company's independent certified public accountants or any executive compensation
consultant, legal counsel or other professional retained by the Company to
assist in the administration of the Plan. No member of the Committee, nor any
officer or Employee of the Company acting on behalf of the Committee, shall be
personally liable for any action, determination or interpretation taken or made
in good faith with respect to the Plan, and all members of the Committee and any
officer or Employee of the Company acting on its behalf shall, to the extent
permitted by law, be fully indemnified and protected by the Company with respect
to any such action, determination or interpretation.

     4. Stock Subject to Plan.

     (a) Amount of Stock Reserved. The total amount of Stock that may be subject
to outstanding awards, determined immediately after the grant of any Award,
shall not exceed 2,500,000 shares of Stock. Notwithstanding the foregoing, the
number of shares that may be delivered as Restricted Stock and Deferred Stock
(other than pursuant to an Award granted under Section 7(e)) shall not in the
aggregate exceed 550,000; provided, however, that the shares subject to
Restricted Stock or Deferred Stock Awards shall not be deemed delivered if such
Awards are forfeited, expire or otherwise terminate without delivery of shares
to the Participant. If an Award valued by reference to Stock may be settled only
in cash, the number of shares to which such Award relates shall be deemed to be
Stock subject to such Award for purposes of this Section 4(a). Any shares of
Stock delivered pursuant to an Award may consist, in whole or in part, of
authorized and unissued shares, treasury shares or shares acquired in the market
for a Participant's account.

     (b) Annual Per-Participant Limitations. During any calendar year, no
Participant may be granted Awards that may be settled by delivery of more than
250,000 shares of Stock, subject

                                       4
<PAGE>   6

to adjustment as provided in Section 4(c). In addition, with respect to Awards
that may be settled in cash (in whole or in part), no Participant may be paid
during any calendar year cash amounts relating to such Awards that exceed the
greater of the Fair Market Value of the number of shares of Stock set forth in
the preceding sentence at the date of grant or the date of settlement of Award.
This provision sets forth two separate limitations, so that Awards that may be
settled solely by delivery of Stock will not operate to reduce the amount of
cash-only Awards, and vice versa; nevertheless, Awards that may be settled in
Stock or cash must not exceed either limitation.

     (c) Adjustments. In the event that the Committee shall determine that any
dividend or other distribution (whether in the form of cash, Stock or other
property), recapitalization, forward or reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase or exchange of Stock or other
securities, liquidation, dissolution, or other similar corporate transaction or
event, affects the Stock such that an adjustment is appropriate in order to
prevent dilution or enlargement of the rights of Participants under the Plan,
then the Committee shall, in such manner as it may deem equitable, adjust any or
all of (i) the number and kind of shares of Stock reserved and available for
Awards under Section 4(a), including shares reserved Restricted and Deferred
Stock, (ii) the number and kind of shares of Stock specified in the annual
per-participant limitations under Section 4(b), (iii) the number and kind of
shares of outstanding Restricted Stock or other outstanding Award in connection
with which shares have been issued, (iv) the number and kind of shares that may
be issued in respect of other outstanding Awards and (v) the exercise price,
grant price or purchase price relating to any Award or, if deemed appropriate,
the Committee may make provision for a cash payment with respect to any
outstanding Award. In addition, the Committee is authorized to make adjustments
in the terms and conditions of, and the criteria included in, Awards in
recognition of unusual or nonrecurring events (including, without limitation,
events described in the preceding sentence) affecting the Company or any
subsidiary or the financial statements of the Company or any subsidiary, or in
response to changes in applicable laws, regulations, or accounting principles.
The foregoing notwithstanding, no adjustments shall be authorized under this
Section 4(c) with respect to Options, SARs or other Awards subject to Section
7(e) to the extent that such authority wold cause such Awards to fail to qualify
as "qualified performance-based compensation" under Section 162(m)(4)(C) of the
Code.

     5. Eligibility. Executive officers and other Employees of the Company and
its subsidiaries, Directors, and persons who provide consulting, advisory, or
other services to the Company deemed by the Committee to be of substantial value
to the Company are eligible to be granted Awards under the Plan. In addition, a
person who has been offered employment by the Company or its subsidiaries is
eligible to be granted an Award under the Plan, provided that such Award shall
be cancelled if such person fails to commence such employment, and no payment of
value may be made in connection with such Award until such person has commenced
such employment.

     6. Specific Terms of Awards.

     (a) General. Awards may be granted on the terms and conditions set forth
in this Section 6. In addition, the Committee may impose on any Award or the
exercise thereof such additional

                                       5
<PAGE>   7
terms and conditions, not inconsistent with the provisions of the Plan, as the
Committee shall determine, including terms requiring forfeiture of Awards in the
event of termination of employment or service of the Participant. Except as
provided in Section 6(f), 6(h), or 7(a), or to the extent required to comply
with requirements of the Delaware General Corporation Law that lawful
consideration be paid for Stock, only services may be required as consideration
for the grant (but not the exercise) of any Award.

     (b) Options. The Committee is authorized to grant Options on the following
terms and conditions ("Options"):

          (i) Nature of Options. Options may be either incentive stock options
     (within the meaning of Section 422 of the Code) ("Incentive Options") or
     Options that do not qualify as Incentive Options ("Nonqualified Options");
     provided, however, that an Incentive Option may be granted only to a person
     who is an Employee on the date of grant of the Option.

          (ii) Exercise Price. The exercise price per share of Stock purchasable
     under an Option shall be determined by the Committee; provided, however,
     that such exercise price shall be not less than the Fair Market Value of a
     share of Stock on the date of grant of such Option; and provided further
     that, in the case of an Incentive Option granted to a person who, on the
     date of grant of the Option, owns stock possessing more than ten percent of
     the total combined voting power of all classes of stock of the Company or
     of any subsidiary of the Company, the exercise price per share of Stock
     purchasable under such Incentive Option shall be not less than 110 percent
     of the Fair Market Value of a share of Stock on the date the Incentive
     Option is granted.

          (iii) Time and Method of Exercise. The Committee shall determine the
     time or times at which an Option may be exercised in whole or in part, the
     methods by which such exercise price may be paid or deemed to be paid, the
     form of such payment, including, without limitation, cash, Stock, other
     Awards or awards granted under other Company plans or other property
     (including notes or other contractual obligations of Participants to make
     payment on a deferred basis, such as through "cashless exercise"
     arrangements, to the extent permitted by applicable law), and the methods
     by which Stock will be delivered or deemed to be delivered to Participants.
     Notwithstanding the foregoing, no Incentive Option shall be exercisable
     after the expiration of ten years from the date such Incentive Option is
     granted; provided, that, in the case of an Incentive Option granted to a
     person who, on the date of grant of the Option, owns stock possessing more
     than ten percent of the total combined voting power of all classes of stock
     of the Company or of any subsidiary of the Company, the Incentive Option
     shall not be exercisable after the expiration of five years from the date
     of grant of the Incentive Option.

          (iv) Termination of Employment. Unless otherwise determined by the
     Committee, upon termination of a Participant's employment with the Company
     and its subsidiaries, such Participant may exercise any Options during the
     three-month period (or such other period as may be specified by the
     Committee in an Award Agreement) following

                                       6
<PAGE>   8

such termination of employment, but only to the extent such Option was
exercisable immediately prior to such termination of employment. Notwithstanding
the foregoing, if the Participant's employment with the Company is governed by
an employment agreement and the Committee determines that such termination is
"for cause" as defined in the Participant's employment agreement, all Options
held by the Participant shall terminate as of the termination of employment
unless otherwise specified in the Participant's Award Agreement.

          (v) Automatic Grants of Options to Nonemployee Directors.

             (A) Effective January 13, 2000, immediately and automatically each
then current Nonemployee Director and, upon initial election to the Board, each
new Nonemployee Director, will receive a Nonqualified Option to purchase 20,000
shares of Common Stock, which will be fully exercisable on the one-year
anniversary of the date of grant, but only if such Nonemployee Director has
continuously served as a director of the Company during such one-year period. In
addition, effective January 13, 2000, each Nonemployee Director will receive a
Nonqualified Stock Option to purchase 30,000 shares of Common Stock at the
annual meeting of stockholders of the Company following the initial year he has
served as a director, if such Nonemployee Director will continue as a director
for the following year (i.e, either through re-election or as a result of his
term not expiring), and every fourth year thereafter (the "Renewal Option").
Each Renewal Option will vest 25% annually, with the initial 25% becoming
exercisable on the date of grant of the option and an additional 25% becoming
exercisable on each of the first anniversaries of the grant date (but only if
such Nonemployee Director is a director of the Company at the time of vesting).
Effective at the Annual Meeting of Directors of the Company to be held on
January 13, 2000, and at each Annual Meeting of Directors thereafter, each
Nonemployee Director who is elected to serve on either the Audit Committee or
Compensation Committee of the Company shall receive an option to purchase 5,000
shares of Common Stock, which option shall be fully exercisable at the end of
the one-year term of such office (but only if such Nonemployee Director serves
on such committee for the entire term).

             (B) The purchase price for Stock acquired pursuant to the exercise
of an Option granted pursuant to this subparagraph (v) shall be the Fair Market
Value of the Stock on the date of the grant of the Option. All Options granted
under this subparagraph (v) shall provide for a period of exercisability of four
years as to each Option (or, where vesting is in 25-percent increments, as to
each vested 25-percent portion of the Option), commencing on the date the Option
(or, if applicable, such 25-percent portion of the Option) vests. If a person
receiving an Option under this subparagraph (v) is not reelected to the Board,
resigns, or is removed from the Board for any reason, then any portion of such
persons Options granted under this subparagraph (v) that is not vested at such
time shall terminate.

             (C) The Committee, in its discretion, may change the terms and
conditions of, and the number of shares of Stock subject to, an Option granted
pursuant to this

                                       7
<PAGE>   9

subparagraph (v) at any time prior to or on the date such Option is to be
automatically granted hereunder.

     (c) Stock Appreciation Rights. The Committee is authorized to grant SARs on
the following terms and conditions ("SARs"):

         (i) Right to Payment. An SAR shall confer on the Participant to whom it
     is granted a right to receive, upon exercise thereof, the excess of the
     Fair Market Value of one share of Stock on the date of exercise (or, if the
     Committee shall so determine in the case of any such right, the Fair Market
     Value of one share at any time during a specified period before or after
     the date of exercise), over the grant price of the SAR as determined by the
     Committee as of the date of grant of the SAR, which, except as provided in
     Section 7(a), shall be not less than the Fair Market Value of one share of
     Stock on the date of grant.

         (ii) Other Terms. The Committee shall determine the time or times at
     which an SAR may be exercised in whole or in part, the method of exercise,
     method of settlement, form of consideration payable in settlement, method
     by which Stock will be delivered or deemed to be delivered to Participants,
     whether or not an SAR shall be in tandem with any other Award, and any
     other terms and conditions of any SAR. Limited SARs that may be exercised
     only upon the occurrence of a change in control of the Company (as defined
     in the applicable Award Agreement) may be granted on such terms, not
     inconsistent with this Section 6(c), as the Committee may determine.
     Limited SARs may be either freestanding or in tandem with other Awards.

         (d) Restricted Stock. The Committee is authorized to grant Restricted
     Stock on the following terms and conditions ("Restricted Stock"):

         (i) Grant and Restrictions. Restricted Stock shall be subject to such
     restrictions on transferability and other restrictions, if any, as the
     Committee may impose, which restrictions may lapse separately or in
     combination at such times, under such circumstances, in such installments,
     or otherwise, as the Committee may determine. Except to the extent
     restricted under the terms of the Plan and any Award Agreement relating to
     the Restricted Stock, a Participant granted Restricted Stock shall have all
     of the rights of a stockholder including, without limitations, the right to
     vote Restricted Stock and the right to receive dividends thereon.

         (ii) Forfeiture. Except as otherwise determined by the Committee, upon
     termination of employment or service (as determined under criteria
     established by the Committee) during the applicable restriction period,
     Restricted Stock that is at that time subject to restrictions shall be
     forfeited and reacquired by the Company; provided, however, that the
     Committee may provide, by rule or regulation or in any Award Agreement, or
     may determine in any individual case, that restrictions or forfeiture
     conditions relating to

                                       8
<PAGE>   10
     Restricted Stock will be waived in whole or in part in the event of
     termination resulting from specified causes.

         (iii) Certificates for Stock. Restricted Stock granted under the Plan
     may be evidenced in such manner as the Committee shall determine. If
     certificates representing Restricted Stock are registered in the name of
     the Participant, such certificates shall bear an appropriate legend
     referring to the terms, conditions, and restrictions applicable to such
     Restricted Stock, the Company may retain physical possession of the
     certificate, and the Committee may require the Participant to deliver a
     stock power to the Company, endorsed in blank, relating to the Restricted
     Stock.

         (iv) Dividends. Dividends paid on Restricted Stock shall be paid at the
     dividend payment dates in cash or in the shares of unrestricted Stock
     having a Fair Market Value equal to the amount of such dividends, or the
     payment of such dividends shall be deferred and/or the amount or value
     thereof automatically reinvested in additional Restricted Stock, other
     Awards, or other investment vehicles, as the Committee shall determine or
     permit the Participant to elect. Stock distributed in connection with a
     Stock split or Stock dividend, and other property distributed as a
     dividend, shall be subject to restrictions and a risk of forfeiture to the
     same extent as the Restricted Stock with respect to which such Stock or
     other property has been distributed, unless otherwise determined by the
     Committee.

         (e) Deferred Stock. The Committee is authorized to grant Deferred Stock
     subject to the following terms and conditions ("Deferred Stock"):

         (i) Award and Restrictions. Delivery of Stock will occur upon
     expiration of the deferral period specified for an Award of Deferred Stock
     by the Committee (or, if permitted by the Committee, as elected by the
     Participant). In addition, Deferred Stock shall be subject to such
     restrictions as the Committee may impose, if any, which restrictions may
     lapse at the expiration of the deferral period or at earlier specified
     times, separately or in combination, in installments or otherwise, as the
     Committee may determine.

         (ii) Forfeiture. Except as otherwise determined by the Committee, upon
     termination of employment or service (as determined under criteria
     established by the Committee) during the applicable deferral period or
     portion thereof to which forfeiture conditions apply (as provided in the
     Award Agreement evidencing the Deferred Stock), all Deferred Stock that is
     at that time subject to such forfeiture conditions shall be forfeited;
     provided, however, that the Committee may provide, by rule or regulation or
     in any Award Agreement, or may determine in any individual case, that
     restrictions or forfeiture conditions relating to Deferred Stock will be
     waived in whole or in part in the event of termination resulting from
     specified causes.

         (f) Bonus Stock and Awards in Lieu of Cash Obligations. The Committee
     is authorized to grant Stock as a bonus, or to grant Stock or other Awards
     in lieu of Company obligations to pay

                                       9
<PAGE>   11

cash under other plans or compensatory arrangements. Stock or Awards granted
hereunder shall be subject to such other terms as shall be determined by the
Committee.

     (g) Dividend Equivalents. The Committee is authorized to grant dividend
equivalents entitling the Participant to receive cash, Stock, other Awards or
other property equal in value to dividends paid with respect to a specified
number of shares of Stock ("Dividend Equivalents"). Dividend Equivalents may be
awarded on a free-standing basis or in connection with another Award. The
Committee may provide that Dividend Equivalents shall be paid or distributed
when accrued or shall be deemed to have been reinvested in additional Stock,
Awards or other investment vehicles, and subject to such restrictions on
transferability and risks of forfeiture, as the Committee may specify.

     (h) Other Stock-Based Awards. The Committee is authorized, subject to
limitations under applicable law, to grant such other Awards ("Other Stock-Based
Awards") that may be denominated or payable in, valued in whole or in part by
reference to, or otherwise based on, or related to, Stock or factors that may
influence the value of Stock, as deemed by the Committee to be consistent with
the purposes of the Plan, including, without limitation, convertible or
exchangeable debt securities, other rights convertible or exchangeable into
Stock, purchase rights for Stock, Awards with value and payment contingent upon
performance of the Company or any other factors designated by the Committee and
Awards valued by reference to the book value of Stock or the value of securities
of or the performance of specified subsidiaries. The Committee shall determine
the terms and conditions of such Awards. Stock issued pursuant to an Award in
the nature of a purchase right granted under this Section 6(h) shall be
purchased for such consideration, paid for at such times, by such methods, and
in such forms, including, without limitation, cash, Stock, other Awards, or
other property, as the Committee shall determine. Cash awards, as an element of
or supplement to any other Award under the Plan, may be granted pursuant to this
Section 6(h).

     7. Certain Provisions Applicable to Awards.

     (a) Stand-Alone, Additional, Tandem, and Substitute Awards. Awards granted
under the Plan may, in the discretion of the Committee, be granted either alone
or in addition to, in tandem with or in substitution for any other Award granted
under the Plan or any award granted under any other plan of the Company, any
subsidiary or any business entity to be acquired by the Company or a subsidiary,
or any other right of a Participant to receive payment from the Company or any
subsidiary. Awards granted in addition to or in tandem with other Awards or
awards may be granted either as of the same time as or a different time from the
grant of such other Awards or awards.

     (b) Term of Awards. The term of each Award shall be for such period as may
be determined by the Committee.

     (c) Form of Payment Under Awards. Subject to the terms of the Plan and any
applicable Award Agreement, payments to be made by the Company or a subsidiary
upon the grant, exercise

                                       10
<PAGE>   12

or settlement of an Award may be made in such forms as the Committee shall
determine, including, without limitation, cash, Stock, other Awards or other
property, and may be in a single payment or transfer, in installments or on a
deferred basis. Such payments may include, without limitation, provisions for
the payment or crediting of reasonable interest on installment or deferred
payments or the grant or crediting of Dividend Equivalents in respect of
installment or deferred payments denominated in Stock.

     (d) Loan Provisions. With the consent of the Committee, and subject at all
times to, and only to the extent, if any, permitted under and in accordance
with, laws and regulations and other binding obligations or provisions
applicable to the Company, the Company may make, guarantee or arrange for a loan
or loans to a Participant with respect to the exercise of any Option or other
payment in connection with any Award, including the payment by a Participant of
any or all federal, state or local income or other taxes due in connection with
any Award. Subject to such limitations, the Committee shall have full authority
to decide whether to make a loan or loans hereunder and to determine the amount,
terms and provisions of any such loan or loans, including the interest rate to
be charged in respect of any such loan or loans, whether the loan or loans are
to be with or without recourse against the borrower, the terms on which the loan
is to be repaid and conditions, if any, under which the loan or loans may be
forgiven.

     (e) Performance-Based Awards. The Committee may, in its discretion,
designate any Award the exercisability or settlement of which is subject to the
achievement of performance conditions as a performance-based Award subject to
this Section 7(e), in order to qualify such Award as "qualified
performance-based compensation" within the meaning of Code Section 162(m) and
regulations thereunder. The performance objectives of an Award subject to this
Section 7(e) shall consist of one or more business criteria and a targeted level
or levels of performance with respect to such criteria, as specified by the
Committee subject to this Section 7(e). Performance objectives shall be
objective, shall be stated in writing not later than ninety (90) days after the
beginning of the period of service to which they relate, and shall otherwise
meet the requirements of Section 162(m)(4)(C) (or successor provisions) of the
Code and the regulations thereunder. Business criteria used by the Committee in
establishing performance objectives for Awards subject to this Section 7(e)
shall be selected exclusively from among the following:

          (1)  Annual return on capital;

          (2)  Annual earnings per share;

          (3)  Annual cash flow provided by operations;

          (4)  Changes in annual revenues; and/or

          (5)  Strategic business criteria, consisting of one or more objectives
               based on meeting specified revenue, market penetration,
               geographic business expansion goals, cost targets, and goals
               relating to acquisitions or divestitures.

                                       11
<PAGE>   13

The levels of performance required with respect to such business criteria may be
expressed in absolute or relative levels. Achievement of performance objectives
with respect to such Awards shall be measured over a period of not less than one
year nor more than five years, as the Committee may specify. Performance
objectives may differ for such Awards to different Participants. The Committee
shall specify the weight to be given to each performance objective for purposes
of determining the final amount payable with respect to any such Award. The
Committee may, in its discretion, reduce the amount of a payout otherwise to be
made in connection with an Award subject to this Section 7(e), but may not
exercise discretion to increase such amount, and the Committee may consider
other performance criteria in exercising such discretion. All determinations by
the Committee as to the achievement of performance objectives shall be in
writing. The Committee may not delegate any responsibility with respect to an
Award subject to this Section 7(e).

     (f) Acceleration. The Committee may accelerate the exercisability or
vesting of any Award in whole or in part at any time and may provide for the
acceleration of any Award in whole or in part upon the occurrence of certain
events as may be set forth in one or more Award Agreements.

     8. General Provisions.

     (a) Compliance With Laws and Obligations. The Company shall not be
obligated to issue or deliver Stock in connection with any Award or take any
other action under the Plan in a transaction subject to the restriction
requirements of the Securities Act of 1933, as amended, or any other federal or
state securities law, any requirement under any listing agreement between the
Company and any national securities exchange or automated quotation system or
any other law, regulation or contractual obligation of the Company until the
Company is satisfied that such laws, regulations, and other obligations of the
Company have been complied with in full. Certificates representing shares of
Stock issued under the Plan will be subject to such stop-transfer orders and
other restrictions as may be applicable under such laws, regulations and other
obligations of the Company, including any requirement that a legend or legends
be placed thereon.

     (b) Limitations on Transferability. Awards and other rights under the Plan,
including any Award or right which constitutes a derivative security as
generally defined in Rule 16a-1(c) under the Exchange Act, will not be
transferable by a Participant except by will or the laws of descent and
distribution or to a Beneficiary in the event of the Participant's death, and,
if exercisable, shall be exercisable during the lifetime of a Participant only
by such Participant or his guardian or legal representative; provided, however,
that such Awards and other rights may be transferred to one or more transferees
during the lifetime of the Participant, and may be exercised by such transferees
in accordance with the terms of such Award, but only if and to the extent then
permitted under Rule 16b-3, consistent with the registration of the offer and
sale of Stock on Form S-8 or Form S-3 or a successor registration form of the
Securities and Exchange Commission, and permitted by the Committee. Awards and
other rights under the Plan may not be pledged, mortgaged, hypothecated or
otherwise encumbered, and shall not be subject to the claims of creditors.

                                       12
<PAGE>   14

     (c) No Right to Continued Employment or Service. Neither the Plan nor any
action taken hereunder shall be construed as giving any Employee or other person
the right to be retained in the employ or service of the Company or any of its
subsidiaries, nor shall it interfere in any way with the right of the Company or
any of its subsidiaries to terminate any Employee's employment or other person's
service at any time.

     (d) Taxes. The Company and any subsidiary is authorized to withhold from
any Award granted or to be settled, any delivery of Stock in connection with an
Award, any other payment relating to an Award or any payroll or other payment to
a Participant amounts of withholding and other taxes due or potentially payable
in connection with any transaction involving an Award, and to take such other
action as the Committee may deem advisable to enable the Company and
Participants to satisfy obligations for the payment of withholding taxes and
other tax obligations relating to any Award. This authority shall include
authority to withhold or receive Stock or other property and to make cash
payments in respect thereof in satisfaction of a Participant's tax obligations.

     (e) Changes to the Plan and Awards. The Board may amend, alter, suspend,
discontinue or terminate the Plan or the Committee's authority to grant Awards
under the Plan without the consent of stockholders or Participants, except that
any such action shall be subject to the approval of the Company's stockholders
at or before the next annual meeting of stockholders for which the record date
is after such Board action if such stockholder approval is required by any
federal or state law or regulation or the rules of any stock exchange or
automated quotation system on which the Stock may then be listed or quoted, and
the Board may otherwise, in its discretion, determine to submit other such
changes to the Plan to Stockholders for approval; provided, however, that,
without the consent of an affected Participant, no such action may materially
impair the rights of such Participant under any Award theretofore granted to
him. The Committee may waive any conditions or rights under, or amend, alter,
suspend, discontinue, or terminate, any Award theretofore granted and any Award
Agreement relating thereto; provided, however, that, without the consent of an
affected Participant, no such action may materially impair the rights of such
Participant under such Award.

     (f) No Rights to Awards: No Stockholder Rights. No Participant or Employee
shall have any claim to be granted any Award under the Plan, and there is no
obligation for uniformity or treatment of Participants and Employees. No Award
shall confer on any Participant any of the rights of a stockholder of the
Company unless and until Stock is duly issued or transferred and delivered to
the Participants in accordance with the terms of the Award or, in the case of an
Option, the Option is duly exercised.

     (g) Unfunded Status of Awards: Creation of Trusts. The Plan is intended to
constitute an "unfunded" plan for incentive and deferred compensation. With
respect to any payments not yet made to a Participant pursuant to an Award,
nothing contained in the Plan or any Award shall give any such Participant any
rights that are greater than those of a general creditor of the Company;
provided, however, that the Committee may authorize the creation of trusts or
make other arrangements to meet the Company's obligations under the Plan to
deliver cash, Stock, other

                                       13
<PAGE>   15

Awards, or other property pursuant to any Award, which trusts or other
arrangements shall be consistent with the "unfunded" status of the Plan unless
the Committee otherwise determines with the consent of each affected
Participant.

     (h) Nonexclusivity of the Plan. Neither the adoption of the Plan by the
Board nor its submission to the stockholders of the Company for approval shall
be construed as creating any limitations on the power of the Board to adopt such
other compensatory arrangements as it may deem desirable, including, without
limitation, the granting of stock options otherwise than under the Plan, and
such arrangements may be either applicable generally or only in specific cases.

     (i) No Fractional Shares. No fractional shares of Stock shall be issued or
delivered pursuant to the Plan or any Award. The Committee shall determine
whether cash, other Awards, or other property shall be issued or paid in lieu of
such fractional shares or whether such fractional shares or any rights thereto
shall be forfeited or otherwise eliminated.

     (j) Compliance with Code Section 162(m). It is the intent of the Company
that Options, SARs and other Awards designated as Awards subject to Section 7(e)
shall constitute "qualified performance-based compensation" within the meaning
of the Code Section 162(m). Accordingly, if any provision of the Plan or any
Award Agreement relating to such an Award does not comply or is inconsistent
with the requirements of Code Section 162(m), such provision shall be construed
or deemed amended to the extent necessary to conform to such requirements, and
no provision shall be deemed to confer upon the Committee or any other person
discretion to increase the amount of compensation otherwise payable in
connection with any such Award upon attainment of the performance objectives.

     (k) Governing Law. The validity, construction and effect of the Plan, any
rules and regulations relating to the Plan and any Award Agreement shall be
determined in accordance with the laws of the State of Delaware, without giving
effect to principles of conflicts of laws, and applicable federal law.

     (l) Effective Date: Plan Termination. The Plan shall become effective as of
May 1, 1998, and shall continue in effect until the earlier of (i) such time as
the Plan is terminated by the Board or (ii) April 30, 2008. This Plan amends and
restates in its entirety the 1996 Long Term Incentive Plan of the Company.

<PAGE>   4

         In the event of the termination of Employee's employment pursuant to
(a), (b), (c), (d) or (f), then Employee shall be entitled to only the
compensation earned by Employee as of, and payable for the period prior to, the
date of such Termination Event. In the event of the termination of Employee's
employment pursuant to (e) above, the Employee shall (i) continue to receive the
salary, provided in Exhibit A for a period of seven (7) months following the
date of termination. Notwithstanding anything to the contrary in this Agreement,
the provisions of Section 5 above shall survive any termination, for whatever
reason, of Employee's employment under this Agreement.

         For purposes of this Section 6 the following terms of the following
meanings:

          "excessive absence" of Employee shall mean his inability, for whatever
     reason, to perform his duties under this Agreement for a continuous period
     of 60 days or for 120 days out of a continuous period of 240 days.

     any act of fraud, moral turpitude or dishonesty, (b) an intentional,
     material violation of a statutory or fiduciary duty not corrected within
     ten days after notice from Employer, (c) any material breach by Employee of
     any of the terms or conditions of, or the failure to perform any material
     covenant contained in, this Agreement and Employee does not cure such
     breach or failure within ten days following notice from Employer; provided,
     however, that Employee will not be entitled to cure any breach or failure
     under this subclause (c) more than one time in any consecutive three (3)
     month period, or (d) the violation by Employee of reasonable instructions
     or policies established by Employer with respect to the operation of its
     business and affairs or Employee's failure to carry out the reasonable
     instructions of the Chief Executive Officer, or Board of Directors of
     Employer and following notice thereof from Employer to Employee, Employee
     does not cure any such violation or failure within ten days following
     notice from Employer; provided, however, that Employee will not be entitled
     to cure any breach or failure under this subclause (d) more than one time
     in any consecutive three (3) month period.

     7. Remedies. Employee recognizes and acknowledges that in the event of any
default in, or breach of any of, the terms, conditions or provisions of this
Agreement (either actual or threatened) by Employee, Employer's and its
affiliates remedies at law shall be inadequate. Accordingly, Employee agrees
that in such event, Employer and its affiliates shall have the right of specific
performance and/or injunctive relief in addition to any and all other remedies
and rights at law, in equity or provided herein, and such rights and remedies
shall be cumulative.

     8. Acknowledgments. Employee acknowledges and recognizes that the
enforcement of any of the provisions set forth in Section 5 above by Employer
and its affiliates will not interfere with Employee's ability to pursue a proper
livelihood. Employee recognizes and agrees that the enforcement of this
Agreement is necessary to ensure the preservation and continuity of the business
and good will of Employer and its affiliates.

                                                                          Page 4

     spent by Optionee at the Company's request on such assistance and the
     Company's requests for assistance shall be reasonable in light of
     Optionee's then existing business commitments. Optionee hereby irrevocably
     appoints the Company, and its duly authorized officers and agents, as
     Optionee's agent and attorney-in-fact to act for and on behalf of Optionee

         thereafter to hold in strict confidence and not to disclose or allow to
         be disclosed to any person, firm or corporation, other than to persons

         affiliates, the Trade Secrets, without the prior written consent of the

         and connectivity business, which is defined as product lines or
         businesses that are competitive with products that are manufactured,
         marketed or sold by the Company and its affiliates during the term of
         his employment or under development during the term of his employment
         (the "Business"); and that he will not act as an officer, director,
         employee, consultant, shareholder, lender, or agent of any entity
         which is competitive with the Business; provided, however, that this
         Section shall not prohibit Optionee or any of his affiliates from
         purchasing or holding an aggregate equity interest of up to 1% in any
         business in competition with the Business. Furthermore, Optionee
         agrees that during his employment with the Company, he will undertake

         with the Business and Optionee will not combine or conspire with any
         other Optionee of the Company and its affiliates for the purpose of
         the organization of any such competitive business activity.

                  (e)      Competition Following Employment. Optionee agrees
         that for a period of one-year after the termination or cessation of
         his employment for the Company for any reason whatsoever, neither he,
         nor any of his affiliates, will directly or indirectly: (1) compete
         with the Company or its affiliates in the Business, and that he will
         not act as an officer, director, Optionee, consultant, shareholder,
         lender, or agent of any entity which is engaged in the Business;
         provided, however, that this Section shall not prohibit Optionee or
         any of his affiliates from purchasing or holding an aggregate equity
         interest of up to 1% in any business in competition with the Business.
         Furthermore, Optionee will not combine or conspire with any other
         Optionees of the Company and its affiliates for the purpose of the
         organization of any such competitive business activity.

         12.      INVENTIONS. In consideration of the grant of Option
hereunder, Optionee agrees to the following:

                  (a)      Disclosure to Company. Optionee agrees to promptly
         disclose to the Company any and all inventions, discoveries,
         improvements, trade secrets, formulas, compositions, coded designs,
         programs, techniques, processes, and know-how, whether or not reduced
         to writing or practice, conceived by Optionee during the period of his
         or her employment with the Company, either alone or jointly with
         others, which relate to or result from the actual or anticipated
         business, work, research or investigations of the Company, or which
         result, to any extent, from use of the Company's premises or property
         (the work being hereinafter collectively referred to as the
         "Intellectual Property"). Further, Optionee shall disclose in
         confidence to the Company all patent and copyright applications filed
         by or on behalf of Optionee during the term of his employment with the
         Company and, to the extent such application related to the business of
         the


<PAGE>   4


         Company at the date Optionee's employment terminates, for a period of
         three (3) years thereafter.

                  (b)      Intellectual Property as Sole Property of the
         Company. Optionee acknowledges and agrees that all the Intellectual
         Property shall be the sole property of Optionee or any other entity
         designated by it, and Optionee hereby assigns to the Company his or
         her entire right and interest in and to all Intellectual Property.
         Optionee further agrees as to all Intellectual Property to assist the
         Company in every way (at the Company's expenses) to obtain and from
         time to time enforce patents and copyrights on the Intellectual
         Property in any and all countries during the term of this Agreement.
         To that end, by way of illustration but not limitation. Optionee will
         testify in any suit or other proceeding involving any of the
         Intellectual Property, execute all documents which the Company
         reasonably determines to be necessary or convenient for use in
         applying for and obtaining patents and copyrights thereon and
         enforcing same, and execute all necessary assignments thereof to the
         Company or persons designated by it. Optionee's obligation to assist
         the Company in obtaining and enforcing patents and copyrights for the
         Intellectual Property shall continue beyond the termination of his
         employment, but the Company shall compensate Optionee at a reasonable
         rate after such termination for the time actually spent by Optionee at
         the Company's request as such assistance and the Company's requests
         for assistance shall be reasonable in light of Optionee's then
         existing business commitments. Optionee hereby irrevocably appoints
         the Company, and its duly authorized officers and agents, as
         Optionee's agent and attorney-in-fact to act for and on behalf of
         Optionee in filing all patent and copyright applications, amendments,
         renewals, and all other appropriate documents in any way related to
         Intellectual Property. The Company will promptly notify Optionee
         following any such filing, provided that the Company will not be
         obligated to make such notification if as a result the Company would
         be in violation of any agreement or order to which it is subject or
         bound.

                  (c)      List of Prior Inventions. As a matter of record,
         Optionee has set forth on Exhibit "A" attached hereto a complete list
         separately identifying each invention, discovery, improvement, trade
         secret, formula, composition, code, design, program, technique,
         process and know-how made or discovered by Optionee prior to his
         employment with the Company. Optionee represents and covenants that
         such list is complete. As a matter of record, Optionee has set forth
         on Exhibit "A" attached hereto a complete list of all inventions,
         programs, discoveries, or improvements relating to the Company's
         business which have been made by Optionee prior to his employment with
         the Company. Optionee represents and covenants that such list is
         complete. All such matters set forth in Exhibit "A", if any, which
         Optionee made prior to his employment by the Company are excluded from
         the scope of this Agreement.

                  (d)      Time of Invention; Presumption. For the purposes of
         this Agreement, an invention or other Intellectual Property is deemed
         to have been made or conceived during the duration of employment if
         during such time, the invention or other Intellectual Property was
         conceived or first actually reduced to writing or practice; and
         Optionee agrees that any disclosure of an invention, Intellectual
         Property or any patent or copyright application made within one (1)
         year after termination of his employment shall be presumed to relate
         to an invention or other Intellectual Property which was made or
         conceived during the term of Optionee's employment unless Optionee
         provides satisfactory and compelling evidence to the contrary.

                  (e)      Training and Experience. Nothing herein is intended
         to prevent or restrict the use by Optionee of Optionee's education,
         training and experience, except insofar as is expressly provided.

         13.      MISCELLANEOUS. This Agreement will be construed and enforced
in accordance with the State of Delaware and will be binding upon and inure to
the benefit of any successor or assign of the Company and any executor,
administrator, trustee, guardian or other legal representative of the Optionee.

         Executed as of the date first above written.

the extent provided herein;

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto hereby agree as follows:

                  Restated 1996 Long Term Incentive Plan (the "Plan"), a copy
                  of which is attached hereto and incorporated herein by
                  reference, the Company grants to the Optionee an option (the
                  "Option") to purchase from the Company all or any part of a
                  total of 50,000 shares of the Company's common stock, par

         stock option" within the meaning of Section 422 of the Internal Revenue
         Code of 1986, as amended (the "Code"); provided, however, that to the
         extent the Option does not qualify as an incentive stock option by
         virtue of exceeding the $100,000 limitation in Section 422(d) of the
         Code, the Option shall be treated as an option other than an incentive
         stock option."

                  Company's stockholders fail to hold at least a majority of
                  the voting stock of the surviving entity; (iii) the sale or
                  other transfer in a single transaction or a series of related

                  provided by a financial institution)); or (vi) December 31,

"Triggering Event"). Optionee agrees that if Optionee exercises any portion of
this Option prior to the occurrence of a Triggering Event and fails to be
employed by the Company at the time of the first occurrence of a Triggering
Event, then Optionee shall forfeit all shares of Common Stock so purchased (and
the Company shall refund to Optionee the exercise price therefor) (the
"Forfeiture"). The Company shall hold any stock certificates to be issued to
Optionee upon exercise of this Option until the occurrence of a Triggering
Event and, in the case of a Forfeiture, the Company shall cancel such stock
certificates so held by the Company.

         C. MISCELLANEOUS.

     1. Employment. Employer hereby employs Employee and Employee hereby accepts
employment with Employer upon the terms and conditions hereinafter set forth.

     2. Duties. Subject to the power of the Board of Directors of Employer (the
"Board") to elect and remove officers, Employee shall serve Employer as Chief
Executive Officer and President of Employer, and shall perform, faithfully and
diligently, the services and functions relating to such office or otherwise
reasonably incident to such office as may be designated from time to time by the
Board. As such, Employee shall report directly to the Board. Employee shall be
based in Scottsdale, Arizona, but shall have duties and responsibilities at
and/or with respect to each location at which Employer or any of its
subsidiaries conducts the Business (as hereinafter defined) and shall travel as
reasonably required by his duties under this Agreement. Employee shall devote
his full time, attention, energies and business efforts to his duties hereunder
and to the promotion of the business and interests of Employer and its
subsidiaries as is customary for an executive vice president of a company of
like-size in a service business; provided, however, that Employee may
participate in other business ventures as long a such participation does not
interfere with Employee's duties hereunder (including those contained in this
sentence).

     3. Term. The term of this Agreement shall commence as of the date hereof
and shall continue, unless earlier terminated pursuant to Section 7 below, for a
period of two (2) years thereafter (the "Initial Term"); provided, however, that

written notice to the other party, at least ninety (90) days prior to the end of
the then current term, of such party's desire to terminate this Agreement at the
end of the then current term. The Initial Term and any Renewal Term(s) are
sometimes collectively referred to herein as the "Term".

     4. Compensation. As compensation for his services rendered under this
Agreement, during the Term Employee shall be entitled to receive the following:

          (e) Expenses. Employer shall reimburse Employee for the expenses

     this Agreement upon submission of a detailed statement and reasonable
     documentation.

     5. Confidentiality.

          (a) Acknowledgment of Proprietary Interest. Employee recognizes the
     proprietary interest of Employer and its affiliates in any Trade Secrets
     (as hereinafter defined) of Employer and its affiliates. Employee

     Employee or learned by Employee during the course of his engagement by
     Employer or otherwise, whether developed by Employee alone or in
     conjunction with others or otherwise, shall be and are the property of
     Employer and its affiliates. Employee further acknowledges and understands
     that his disclosure of any Trade Secrets may result in irreparable injury
     and damage to Employer and its affiliates. As used herein, "Trade Secrets"
     means all confidential and proprietary information of Employer and its
     affiliates, now owned or hereafter acquired, including, without limitation,
     information derived from reports, investigations, experiments, research,
     work in progress, drawing, designs, plans, proposals, codes, marketing and

     affiliates, or any of their respective customers, other than information
     which is otherwise publicly available.

          (b) Covenant Not-to-Divulge Trade Secrets. Employee acknowledges and
     agrees that Employer and its affiliates are entitled to prevent the
     disclosure of Trade Secrets. As a portion of the consideration for the
     employment of Employee and for the compensation being paid to Employee by
     Employer, Employee agrees at all times during the Term and for a period of
     five (5) years thereafter to hold in strict confidence and not to
     intentionally disclose (except for such disclosures as are required by law,
     in which case, Employee agrees to give Employer notice thereof prior to
     making any such disclosure) or allow to be disclosed to any person, firm or
     corporation, other than to persons engaged by Employer and its affiliates
     to further the business of Employer and its affiliates, and not to use
     except in the pursuit of the business of Employer and its affiliates, the
     Trade Secrets, without the prior written consent of Employer, including
     Trade Secrets developed by Employee.

          (c) Return of Materials at Termination. In the event of any
     termination or cessation of his employment with Employer for any reason
     whatsoever, Employee will promptly deliver to Employer all documents, data
     and other information pertaining to Trade Secrets. Employee shall not take
     any documents or other information, of whatever type and in whatever form,
     or any reproduction or excerpt thereof, containing or pertaining to any
     Trade Secrets.

          (d) Competition During and After Employment. Employee agrees that
     during the Term and for a period of one year thereafter, neither Employee,
     nor any of his affiliates, will directly or indirectly act as an investor,
     principal, member, partner, officer, director, employee, consultant,
     shareholder, lender, or agent of any entity which is engaged in any
     business of the same nature as, or in competition with, the business
     conducted by Employer and its subsidiaries during the Term (the "Business")
     within the World; provided, however, that: (i) this Section 5(d) shall not
     prohibit Employee or any of his affiliates from purchasing or holding an
     aggregate equity interest of not more than 1% in any business in
     competition with the Business being conducted by Employer and its
     subsidiaries; (ii) this Section 5(d) shall not apply if a termination
     occurs pursuant to subpart (f) of the first paragraph of Section 7 below;
     or (iii) this Section 5(d) shall not apply if a termination of Employee's
     employment occurs and the conditions of Section 8(a) below have been
     satisfied.

this Agreement forward, refrain from making disparaging, negative or other

date of such Termination Event. In the event of the termination of Employee's
employment pursuant to (e) or (g) above, then Employee shall be entitled to

          "Disability" of Employee shall mean his inability, because of mental
     or physical illness or incapacity, to perform his duties under this
     Agreement for a continuous period of 90 consecutive days or for any 120
     days out of a 360-day period. In the event of any disagreement between
     Employer and Employee regarding the existence or non-existence of any such
     disability, upon written request from either party to the other, Employer
     and Employee or his legal guardian or duly authorized attorney-in-fact (if
     he is not legally competent) shall each designate one Arizona licensed
     physician and the two physicians so designated shall designate a third. All
     three physicians so appointed shall personally examine Employee, and the
     decision of a majority of such panel of physicians shall determine whether
     such disability exists. Employee hereby authorizes the disclosure and
     release to Employer of such determination and all supporting medical
     records, and both parties hereby agree to be bound by such determination.

          "Just Cause" shall mean: (a) the commission by Employee of any act
     involving moral turpitude or the commission by Employee of any act or the
     suffering by Employee of any occurrence or state of facts, which renders
     Employee incapable of performing his duties under this Agreement (other
     than Disability), or adversely affects or could be expected to adversely
     affect Employer's business reputation; (b) Employee's being convicted of a
     felony; (c) any breach by Employee of any of the material terms of, or the
     failure to perform any material covenant contained in, this Agreement and
     following written notice thereof from Employer to Employee, Employee does
     not cure such breach or failure within fifteen (15) days thereafter;
     provided, however, that Employee will not be entitled to cure any breach or
     failure under this subclause (c) more than one time in any consecutive six
     month period; (d) the violation by Employee of reasonable and appropriate
     instructions or policies established by Employer which have been
     communicated to Employee with respect to the operation of their businesses
     and affairs or Employee's failure to carry out the reasonable instructions
     of the Board and following written notice thereof from Employer to
     Employee, Employee does not cure any such violation or failure within
     fifteen (15) days thereafter; provided, however, that Employee will not be
     entitled to cure any violation or failure under this subclause (d) more
     than one time in any consecutive six month period; or (e) the commission by
     Employee of any act or the existence of any state of facts which would
     legally justify an employer in terminating a contract of employment.

     8. Change in Control; Change in Chief Executive Officer.

          (a) Termination Payment. Notwithstanding anything to the contrary
     contained in Section 7 above, if Employee's employment with Employer is
     terminated by: (i) Employer by reason of subpart (e) of the first paragraph
     of Section 7 above; or (ii) Employee by reason of subpart (h) of the first
     paragraph of Section 7 above, and, in either case, such termination
     occurred within two (2) years following a Change In Control (as defined in
     subparagraph (b) below), then, in either event, Employee shall be entitled
     to continue to receive a lump-sum payment equal to the Employee's then
     current Salary for the remainder of the then applicable Term.

<PAGE>   6

          (b) Change In Control. A "Change In Control" will be deemed to have
     occurred for purposes hereof: (i) upon the consolidation or merger of
     Employer with or into another corporation or business entity pursuant to
     which immediately following such merger or consolidation, Employer's
     stockholders fail to hold at least a majority of the voting stock of the
     surviving entity or its ultimate parent corporation; (ii) upon the sale or
     other transfer in a single transaction or a series of related transactions
     of all or substantially all of the assets of Employer, except to a
     subsidiary of Employer; or (iii) upon the acquisition of beneficial
     ownership, directly or indirectly, by any person (as such term is used in
     Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as

and good will of Employer and its affiliates.

shall be binding upon and inure to the benefit of Employer and Employee, and
their respective heirs, personal representatives, successors and assigns.
Employer shall have the right to assign this Agreement to any affiliate or to

Agreement be enforced to the fullest extent permitted by applicable law.

to the foregoing.

counterparts, each of which shall be deemed an original and all of which shall

                                                               MOLLO, CHARLES R.


                           MOBILITY ELECTRONICS, INC.
                      NON-QUALIFIED STOCK OPTION AGREEMENT


         This Non-Qualified Stock Option Agreement (the "Agreement") dated as of
December 1, 1999 is entered into between Mobility Electronics, Inc., a Delaware
corporation (the "Company"), and Charles R. Mollo, an employee of the Company
(the "Optionee"). In consideration of the mutual promises and covenants made
herein, the parties hereby agree as follows:

         1. GRANT OF OPTION. Under the terms and conditions of the Company's
Amended and Restated 1996 Long Term Incentive Plan (the "Plan"), a copy of which
is attached hereto and incorporated herein by reference, the Company grants to
the Optionee an option (the "Option") to purchase from the Company all or any
part of a total of 200,000 shares of the Company's Common Stock, par value $.01
per share, at a price of $2.00 per share. The Option is granted as of the date
first above written (the "Date of Grant").

         2. CHARACTER OF OPTION. The Option is not an "incentive stock option"
within the meaning of Section 422 of the Internal Revenue Code of 1986, as
amended.

         3. TERM. The Option will expire on the earliest of: (i) the fifth
anniversary of the Date of Grant or, (ii) one year following the termination of
Optionee's employment with the Company.

         4. VESTING. Subject to the provisions of Section 6(b) of the Plan, this
option shall be exercised (and shall vest) on the basis of 4,762 shares per
month for 41 months, commencing on January 1, 2000, and 4,758 shares on the 42nd
month, with such exercisability being on the first day of each such month.
Notwithstanding the above, the Option will be exercisable, and vest, in full:
(i) upon a Change In Control (as defined in the Employment Agreement, of even
date herewith, by and between the Company and Optionee); or (ii) if the Common
Stock is then trading on a national securities exchange or the Nasdaq National
Market and the closing price of the Common Stock for ninety consecutive trading
dates on such exchange or market exceeds $8.00 per share (as adjusted for stock
splits, stock dividends, reorganizations and the like occurring after the date
hereof). Notwithstanding anything herein to the contrary, except as provided
above in this Section 4, upon termination of Employee's employment with the

                              EMPLOYMENT AGREEMENT


         This Employment Agreement (this "Agreement") is made and entered into
as of the 1st day of December, 1999, by and between Mobility Electronics, Inc.,
a Delaware corporation ("Employer"), and Jeffrey S. Doss ("Employee").

                              W I T N E S S E T H:

         WHEREAS, Employer desires to employ Employee as provided herein, and
Employee desires to accept such employment; and

         WHEREAS, Employee shall, as an employee of Employer, have access to
confidential information with respect to Employer and its affiliates;

         NOW THEREFORE, for and in consideration of the mutual covenants and
agreements contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto
agree as follows:

         1.       Employment. Employer hereby employs Employee and Employee
hereby accepts employment with Employer upon the terms and conditions
hereinafter set forth.

         2.       Duties. Subject to the power of the Board of Directors of
Employer (the "Board") to elect and remove officers, Employee shall serve
Employer as an Executive Vice President of Employer, and shall perform,
faithfully and diligently, the services and functions relating to such office or
otherwise reasonably incident to such office as may be designated from time to
time by the Board or the Chief Executive Officer of Employer. As such, Employee
shall report directly to the Chief Executive Officer of Employer. Employee shall
be based in Scottsdale, Arizona, but shall have duties and responsibilities at
and/or with respect to each location at which Employer or any of its
subsidiaries conducts the Business (as hereinafter defined) and shall travel as
reasonably required by his duties under this Agreement. Employee shall devote
his full time, attention, energies and business efforts to his duties hereunder
and to the promotion of the business and interests of Employer and its
subsidiaries as is customary for an executive vice president of a company of
like-size in a service business; provided, however, that Employee may
participate in other business ventures as long a such participation does not
interfere with Employee's duties hereunder (including those contained in this
sentence).

         3.       Term. The term of this Agreement shall commence as of the date
hereof and shall continue, unless earlier terminated pursuant to Section 7
below, for a period of two (2) years thereafter (the "Initial Term"); provided,
however, that the term of this Agreement shall thereafter

be renewed on a year-to-year basis thereafter (each, a "Renewal Term"), unless
either party gives written notice to the other party, at least ninety (90) days
prior to the end of the then current term, of such party's desire to terminate
this Agreement at the end of the then current term. The Initial Term and any
Renewal Term(s) are sometimes collectively referred to herein as the "Term".

         4.       Compensation. As compensation for his services rendered under
this Agreement, during the Term Employee shall be entitled to receive the
following:

                  (a)      Salary. Employee shall be paid a salary as provided
         in Exhibit A (the "Salary").

         bonuses as provided in Exhibit A.

                  (c)      Stock Options. As of the date hereof, Employer shall
         execute and deliver to Employee a Stock Option Agreement, the form of
         which is attached hereto as Exhibit B-1. In addition, Employer and
         Employee agree to amend that certain Option Agreement, dated as of
         August 23, 1996, by and between Employer and Employee as provided in
         Exhibit B-2 attached hereto.

                  (d)      Purchase of Stock. On the date hereof, Employer shall
         sell to Employee, and Employee shall purchase from Employer 50,000
         shares of Series C Preferred Stock, par value $0.01 per share (the
         "Series C Preferred Stock"), at a purchase price of $6.00 per share,
         and for no additional consideration, Employer shall issue to Employee a
         warrant to purchase 100,000 shares of the common stock, par value $0.01
         per share, of the Company, at an exercise price of $0.01 per share (the
         "Warrant"). In consideration therefore, on the date hereof, Employee
         shall: execute and deliver to Employer: (i) a promissory note, in the
         form attached hereto as Exhibit C-1; (ii) a Pledge Agreement, in the
         form attached hereto as Exhibit C-2; and (iii) five (5) stock powers,
         executed in blank, and in the form attached hereto as Exhibit C-3; and

         attached hereto as Exhibit C-4.

                  (e)      Benefits. Employee shall also be entitled to receive
         such group benefits as Employer may provide to its other employees at
         comparable salaries and responsibilities to those of Employee. In
         addition, Employee shall be entitled to receive the benefits set forth
         on Exhibit A.

                  (f)      Expenses. Employer shall reimburse Employee for all
         reasonable out-of-pocket travel and other expenses incurred by Employee
         in rendering services required under this Agreement upon submission of
         a detailed statement and reasonable documentation.

                  5.       Confidentiality.

                  (a)      Acknowledgment of Proprietary Interest. Employee
         recognizes the proprietary interest of Employer and its affiliates in
         any Trade Secrets (as hereinafter defined) of Employer and its
         affiliates. Employee acknowledges and agrees that any and all Trade
         Secrets currently known by Employee or learned by Employee during the
         course of his engagement by Employer or otherwise, whether developed by
         Employee alone or in conjunction with others or otherwise, shall be and
         are the property of Employer and its affiliates. Employee further
         acknowledges and understands that his disclosure of any Trade Secrets
         may result in irreparable injury and damage to Employer and its
         affiliates. As used herein, "Trade Secrets" means all confidential and
         proprietary information of Employer and its affiliates, now owned or
         hereafter acquired, including, without limitation, information derived
         from reports, investigations, experiments, research, work in progress,
         drawing, designs, plans, proposals, codes, marketing and sales
         programs, client lists, client mailing lists, financial projections,
         cost summaries, pricing formula, and all other concepts, ideas,
         materials, or information prepared or performed for or by Employer or
         its affiliates and information related to the business, products or
         sales of Employer or its affiliates, or any of their respective
         customers, other than information which is otherwise publicly
         available.

                  (b)      Covenant Not-to-Divulge Trade Secrets. Employee
         acknowledges and agrees that Employer and its affiliates are entitled
         to prevent the disclosure of Trade Secrets. As a portion of the
         consideration for the employment of Employee and for the compensation
         being paid to Employee by Employer, Employee agrees at all times during
         the Term and for a period of five (5) years thereafter to hold in
         strict confidence and not to intentionally disclose (except for such
         disclosures as are required by law, in which case, Employee agrees to
         give Employer notice thereof prior to making any such disclosure) or
         allow to be disclosed to any person, firm or corporation, other than to
         persons engaged by Employer and its affiliates to further the business
         of Employer and its affiliates, and not to use except in the pursuit of
         the business of Employer and its affiliates, the Trade Secrets, without
         the prior written consent of Employer, including Trade Secrets
         developed by Employee.

                  (c)      Return of Materials at Termination. In the event of
         any termination or cessation of his employment with Employer for any
         reason whatsoever, Employee will promptly deliver to Employer all
         documents, data and other information pertaining to Trade Secrets.
         Employee shall not take any documents or other information, of whatever
         type and in whatever form, or any reproduction or excerpt thereof,
         containing or pertaining to any Trade Secrets.

                  (d)      Competition During and After Employment. Employee
         agrees that during the Term and for a period of one year thereafter,
         neither Employee, nor any of his affiliates, will directly or
         indirectly act as an investor, principal, member, partner, officer,
         director, employee, consultant, shareholder, lender, or agent of any
         entity which is engaged in any

         business of the same nature as, or in competition with, the business
         conducted by Employer and its subsidiaries during the Term (the
         "Business") within the World; provided, however, that this Section 5(d)
         shall not prohibit Employee or any of his affiliates from purchasing or
         holding an aggregate equity interest of not more than 1% in any
         business in competition with the Business being conducted by Employer
         and its subsidiaries. Notwithstanding anything in this Agreement to the
         contrary, Employer may, at its option, elect to extend the term of this
         paragraph 5(d) for a period of one extra year after the termination of
         this Agreement (i.e., for a total of two (2) years following such
         termination), by written notice to Employee at least ninety (90) days
         prior to the expiration of the original one-year period following such
         termination, in which event Employee shall be entitled to receive,
         within ten (10) days following Employer's election, an amount equal to
         Employee's annual Salary at the time of such termination.

                  6.       Prohibition on Disparaging Remarks. Employee shall,
from the date of this Agreement forward, refrain from making disparaging,
negative or other similar remarks concerning Employer or any of its affiliates
to any third party. Similarly, Employer and its affiliates shall from the date
of this Agreement forward, refrain from making disparaging, negative or other
similar remarks concerning Employee to any third party.

                  7.       Termination. This Agreement and the employment
relationship created hereby shall terminate upon the occurrence of any of the
following events (each, a "Termination Event"):

                  (a)      The expiration of the Term as set forth in Section 3
         above;

                  (b)      The death of Employee;

                  (c)      The Disability (as hereinafter defined) of Employee;

                  (d)      Written notice to Employee from Employer of
         termination for Just Cause (as hereinafter defined);

                  (e)      Written notice to Employee from Employer of
         termination for any reason other than Just Cause;

                  (f)      Written notice to Employer from Employee of
         termination for any reason other than Constructive Termination (as
         hereinafter defined); or

                  (g)      Written notice to Employer from Employee of
         termination for Constructive Termination.

         In the event of the termination of Employee's employment pursuant to
(a), (b), (c), (d) or (f) above, then Employee shall be entitled to only the
compensation earned by Employee as of, and


Employment Agreement - Jeffrey S. Doss                                    Page 4


<PAGE>   5

payable for the period prior to, the date of such Termination Event. In the
event of the termination of Employee's employment pursuant to (e) or (g) above,
then Employee shall be entitled to continue to receive the Salary for the
remainder of the then applicable Term; provided however, that if such
termination occurs more than one year following the date of this Agreement, then
Employee shall be entitled to receive only the compensation earned by Employee
as of, and payable for the period prior to, the date of such Termination Event,
plus a lump-sum amount equal to three (3) months of Employee's then current
Salary. Notwithstanding anything to the contrary in this Agreement, the
provisions of Sections 5 and 6 above shall survive any termination, for whatever
reason, of Employee's employment under this Agreement.

         For purposes of this Section 7 the following terms of the following
meanings:

                  "Constructive Termination" shall mean: (a) a material
         reduction in Employee's duties and responsibilities without Employee's
         consent; (b) any breach by Employer of any of the material terms of, or
         the failure to perform any material covenant contained in this
         Agreement and following written notice thereof from Employee to
         Employer, Employer does not cure such breach or failure within fifteen
         (15) days thereafter; provided, however, that Employer will not be
         entitled to cure any such breach or failure more than one time in any
         consecutive three month period; (c) a required relocation by Employee
         from the Phoenix, Arizona metroplex; (d) if Employee no longer reports
         directly to the Chief Executive Officer of Employer; or (e) a reduction
         in Employee's Salary without Employee's prior written consent.

                  "Disability" of Employee shall mean his inability, because of
         mental or physical illness or incapacity, to perform his duties under
         this Agreement for a continuous period of 90 consecutive days or for
         any 120 days out of a 360-day period. In the event of any disagreement
         between Employer and Employee regarding the existence or non-existence
         of any such disability, upon written request from either party to the
         other, Employer and Employee or his legal guardian or duly authorized
         attorney-in-fact (if he is not legally competent) shall each designate
         one Arizona licensed physician and the two physicians so designated
         shall designate a third. All three physicians so appointed shall
         personally examine Employee, and the decision of a majority of such
         panel of physicians shall determine whether such disability exists.
         Employee hereby authorizes the disclosure and release to Employer of
         such determination and all supporting medical records, and both parties
         hereby agree to be bound by such determination.

                  "Just Cause" shall mean: (a) the commission by Employee of any
         act involving moral turpitude or the commission by Employee of any act
         or the suffering by Employee of any occurrence or state of facts, which
         renders Employee incapable of performing his duties under this
         Agreement (other than Disability), or adversely affects or could be
         expected to adversely affect Employer's business reputation; (b)
         Employee's being convicted of a felony; (c) any breach by Employee of
         any of the material terms of, or the failure to perform any



Employment Agreement - Jeffrey S. Doss                                    Page 5

         material covenant contained in, this Agreement and following written
         notice thereof from Employer to Employee, Employee does not cure such
         breach or failure within fifteen (15) days thereafter; provided,
         however, that Employee will not be entitled to cure any breach or
         failure under this subclause (c) more than one time in any consecutive
         six month period; (d) the violation by Employee of reasonable and
         appropriate instructions or policies established by Employer which have
         been communicated to Employee with respect to the operation of their
         businesses and affairs or Employee's failure to carry out the
         reasonable instructions of the President of Employer or the Board and
         following written notice thereof from Employer to Employee, Employee
         does not cure any such violation or failure within fifteen (15) days
         thereafter; provided, however, that Employee will not be entitled to
         cure any violation or failure under this subclause (d) more than one
         time in any consecutive six month period; or (e) the commission by
         Employee of any act or the existence of any state of facts which would
         legally justify an employer in terminating a contract of employment.

         8.       Change in Control; Change in Chief Executive Officer.


                  (a)      Termination Payment. Notwithstanding anything to the
         contrary contained in Section 7 above, if Employee's employment with
         Employer is terminated by: (i) Employer by reason of subpart (e) of the
         first paragraph of Section 7 above; or (ii) Employee by reason of
         subpart (g) of the first paragraph of Section 7 above, and, in either
         case, such termination occurred within two (2) years following a Change
         In Control (as defined in subparagraph (b) below), then, in either
         event, Employee shall be entitled to continue to receive the Salary for
         the remainder of the then applicable Term plus one (1) year.

                  (b)      Change In Control. A "Change In Control" will be
         deemed to have occurred for purposes hereof: (i) upon the consolidation
         or merger of Employer with or into another corporation or business
         entity pursuant to which immediately following such merger or
         consolidation, Employer's stockholders fail to hold at least a majority
         of the voting stock of the surviving entity or its ultimate parent
         corporation; (ii) upon the sale or other transfer in a single
         transaction or a series of related transactions of all or substantially
         all of the assets of Employer, except to a subsidiary of Employer; or
         (iii) upon the acquisition of beneficial ownership, directly or
         indirectly, by any person (as such term is used in Sections 13(d) and
         14(d)(2) of the Securities Exchange Act of 1934, as amended) of
         securities of Employer representing more than fifty percent (50%) of
         the combined voting power of Employer's then outstanding voting
         securities.

                  (c)      Change in Chief Executive Officer. Employer shall
         consult Employee with respect to any change in the current Chief
         Executive Officer of Employer, and shall seek Employer's approval of
         any new Chief Executive Officer (the "New CEO"), which approval shall
         not be unreasonably withheld. If Employee does not approve of the New
         CEO, Employee shall have the right to terminate this Agreement and his
         employment with Employer (the "CEO Termination Event") within thirty
         (30) days after the start date of the



Employment Agreement - Jeffrey S. Doss                                    Page 6

<PAGE>   7

         New CEO, by delivering a written resignation to Employer. In the event
         of the occurrence of a CEO Termination Event, Employee shall be
         entitled to receive only the compensation earned by Employee as of, and
         payable for the period prior to, the date of such written resignation,
         plus a lump-sum equal to three (3) months of Employee's then current
         Salary.

         9.       Remedies. Employee recognizes and acknowledges that in the
event of any default in, or breach of any of, the terms, conditions or
provisions of this Agreement (either actual or threatened) by Employee,
Employer's and its affiliates remedies at law shall be inadequate. Accordingly,
Employee agrees that in such event, Employer and its affiliates shall have the
right of specific performance and/or injunctive relief in addition to any and
all other remedies and rights at law, in equity or provided herein, and such
rights and remedies shall be cumulative.

         10.      Acknowledgments. Employee acknowledges and recognizes that the
enforcement of any of the provisions set forth in Section 5 and 6 above by
Employer and its affiliates will not interfere with Employee's ability to pursue
a proper livelihood. Employee recognizes and agrees that the enforcement of this
Agreement is necessary to ensure the preservation and continuity of the business
and good will of Employer and its affiliates.

         11.      Notices. Any notices, consents, demands, requests, approvals
and other communications to be given under this Agreement by either party to the

substantially all of Employer's assets or all of its stock, or with which
Employer merges or consolidates. The rights, duties or benefits to Employee
hereunder are personal to him, and no such right, duty or benefit may be

balance of this Agreement be enforced to the fullest extent permitted by

narrower scope as it determines enforceable.

                           MOBILITY ELECTRONICS, INC.
                      NON-QUALIFIED STOCK OPTION AGREEMENT


         This Non-Qualified Stock Option Agreement (the "Agreement") dated as

granted as of the date first above written (the "Date of Grant").

         2.       CHARACTER OF OPTION. The Option is not an "incentive stock
option" within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended.

         3.       TERM. The Option will expire on the earliest of: (i) the
fifth anniversary of the Date of Grant or, (ii) one year following the
termination of Optionee's employment with the Company.

shares per month for 35 months, commencing on January 1, 2000, and 4,155 shares
on the 36th month, with such exercisability being on the first day of each such
month. Notwithstanding the above, the Option will be exercisable, and vest, in
full: (i) upon a Change In Control (as defined in the Employment Agreement, of
even date herewith, by and between the Company and Optionee); or (ii) if the
Common Stock is then trading on a national securities exchange or the Nasdaq
National Market and the closing price of the Common Stock for ninety
consecutive trading dates on such exchange or market exceeds $10.00 per share
(as adjusted for stock splits, stock dividends, reorganizations and the like
occurring after the date hereof). In addition, notwithstanding the above, upon
the occurrence of a CEO Termination Event, this Option shall become exercisable
for an additional six (6) months amount of shares (e.g., if the event occurred
in month 20, additional shares equal to 4,155 multiplied by 6), in addition to
the then exercisable portion of this Option. Notwithstanding anything herein to
the contrary, except as provided above in this Section 4, upon termination of
Employee's employment with the Company, for any reason, the unvested portion of
the Option shall immediately terminate.


         5.       PROCEDURE FOR EXERCISE. Exercise of the Option or a portion
thereof shall be effected by the giving of written notice to the Company and
payment of the purchase price prescribed in Section 1 above for the shares to
be acquired pursuant to the exercise.

         6.       PAYMENT OF PURCHASE PRICE. Payment of the purchase price for
any shares purchased pursuant to the Option shall be in cash, unless otherwise
agreed to in writing by the Compensation Committee of the Board of Directors of
the Company.

         7.       TRANSFER OF OPTIONS. The Option may not be transferred except
by will or the laws of descent and distribution and, during the lifetime of the
Optionee, may be exercised only by the Optionee or by the Optionee's legally
authorized representative.

         8.       ACCEPTANCE OF THE PLAN. The Option is granted subject to all
of the applicable terms and provisions of the Plan, and such terms and
provisions are incorporated by reference herein. The Optionee hereby accepts
and agrees to be bound by all the terms and conditions of the Plan.

         9.       AMENDMENT. This Agreement may be amended by an instrument in
writing signed by both the Company and the Optionee.

         10.      MISCELLANEOUS. This Agreement will be construed and enforced
in accordance with the laws of the State of Delaware and will be binding upon
and inure to the benefit of any successor or assign of the Company and any
executor, administrator, trustee, guardian or other legal representative of the
Optionee.

                                PLEDGE AGREEMENT


         THIS PLEDGE AGREEMENT (this "Agreement") is made as of the 1st day of
December, 1999, by and between Jeffrey S. Doss ("Debtor"), and Mobility
Electronics, Inc., a Delaware corporation ("Secured Party").

                                    RECITALS

         WHEREAS, concurrently with the execution and delivery of this
Agreement, Debtor has executed and delivered to Secured Party a Promissory Note
(the "Note") in the original principal amount of $300,000.00, bearing interest
and payable as to principal and interest as therein set forth; and

         WHEREAS, the Note evidences the purchase price payable to Secured Party
by Debtor for 50,000 shares of Series C Preferred Stock, par value $0.01 per
share, of Secured Party (the "Preferred Shares"), and a warrant (the "Warrant")
to purchase up to 100,000 shares of the common stock, par value $0.01 per share,
of Secured Party (the "Common Stock"); and

         WHEREAS, Debtor has agreed, on the terms set out herein, to secure the
payment and performance of the Note by granting a security interest in the
Pledged Securities (as hereinafter defined) to the Secured Party;

         NOW, THEREFORE, the parties hereto hereby agree as follows:

                                    AGREEMENT

         1. DEFINITIONS. As used in this Agreement, the following terms shall
have the meaning indicated:


                   (a)  "Pledged Securities" means the Preferred Shares, the
              Warrant and the shares of Common Stock underlying the Preferred
              Shares and the Warrant, and any and all substitutes, replacements,
              accessions, attachments and other additions thereto, and any and
              all proceeds from the sale thereof.

                   (b)  "Secured Indebtedness" means all sums payable under
              the Note and any substitutions, extensions, renewals or
              re-amortizations of the Note.

         2. GRANT OF SECURITY INTEREST IN THE PLEDGED SECURITIES. To secure the
full and punctual payment of the Secured Indebtedness, and upon and subject to
the terms, provisions and conditions of this Agreement, Debtor does hereby grant

<PAGE>   2


         3. DELIVERY OF SECURITIES TO SECURED PARTY. Simultaneously with the
execution of this Agreement: (i) the stock certificate representing the
Preferred Shares and the Warrant and all other stock certificates and
instruments in registered form which may constitute or evidence at any time or
from time to time a part of the Pledged Securities shall be delivered to the
Secured Party and shall be endorsed in blank for transfer or be accompanied by
proper instruments of assignment and transfer in blank upon delivery; and (ii)
Debtor shall execute and deliver to Secured Party five stock powers, executed in
blank, and one warrant assignment, executed in blank, each in a form acceptable
to Secured Party. Until the happening of an event of Default hereunder, all
certificates and instruments representing the Pledged Securities shall remain
registered in the name of Debtor. So long as the Secured Indebtedness, or any
part thereof, remains outstanding and unpaid, the certificate and instruments
representing the Pledged Securities, shall be held by Secured Party, and Debtor
shall not have the right to procure the release of any of the Pledged Securities
from the lien hereby created except upon and in compliance with the terms and
conditions herein set forth.

         4. COVENANTS OF DEBTOR. Debtor covenants and agrees that Debtor shall
promptly pay and discharge the Secured Indebtedness and any and all other debts,
obligations or liabilities, including expenses and reasonable attorneys' fees,
incurred or paid by Secured Party in exercising or protecting its interests,
rights and remedies hereunder as and when the same shall become due and payable,
either by their own terms or by the exercise by Secured Party of any right or
option which they may ever have to accelerate the maturity thereof.

         5. VOTING OF PLEDGED SECURITIES. Until the occurrence of an event of
Default, the Pledged Securities shall be treated as shares of Debtor and Debtor
shall be entitled to vote at any meeting of the stockholders of Secured Party.
Until the occurrence of an event of Default, no cash dividends shall be payable
to Secured Party on or with respect to the Pledged Securities. Debtor hereby
grants to Secured Party, upon the occurrence of an event of Default hereunder,
the right to vote the Pledged Securities during the continuance of such Default
whether or not Secured Party seek any other remedies available to it under this
Agreement or any applicable law or in equity.

         6. DEFAULT. The term "Default" means an "Event of Default" under the
Note, all of the terms, covenants, conditions and provisions of which are
incorporated in this Agreement by reference the same as if set forth verbatim,
and such terms, covenants, conditions, and provisions shall continue in full
force and effect under this Agreement until the Secured Indebtedness is paid in
and performed in full.

         7. REMEDIES UPON DEFAULT.

                  (a) If any event of Default set forth in Paragraph 6 above
         shall occur, Secured Party may seek any remedies available to them
         under any applicable law.


                                       -2-
<PAGE>   3


                  (b) Except as otherwise provided herein or in the Note, Debtor
         hereby waives notice of Default, presentment for payment, demand,
         notice of dishonor and protest of the Note.

                  (c) In addition, full power and authority are hereby given to
         Secured Party to sell, assign and deliver the whole or any part of the
         Pledged Securities at any broker's board, or at public or private sale,
         at the option of Secured Party, either for cash or on credit or for
         future delivery without assumption of any credit risk, and without
         either demand or advertisement of any kind, both of which are hereby
         waived, and no delay on the part of Secured Party in exercising any
         power of sale or any other rights or option hereunder, and no demand,
         which may be given to or made upon the undersigned by Secured Party to
         a power of sale or other right or option hereunder, shall constitute a
         waiver thereof, or limit or impair the right of Secured Party to take
         any action or to exercise any power of sale or any other rights
         hereunder, without demand, or prejudice the rights of Secured Party as
         against the undersigned in any respect. At any sale of the Pledged
         Securities in accordance with the preceding sentence, Debtor may itself
         purchase the whole or any part of the Pledged Securities sold. In event
         of any sale or other disposition of any of the Pledged Securities,
         after deducting all costs or expenses of every kind for care,
         safekeeping, collection, sale, delivery or otherwise, Secured Party
         shall, after applying the residue of the proceeds of the sale, or other
         disposition thereof, as hereinabove authorized, return any excess to
         Debtor. Secured Party shall notify Debtor in writing of their intent to
         exercise its right to sell the Pledged Securities in accordance with
         this Section 7(c) at least five (5) days prior to any such sale.

                  Because of the Securities Act of 1933, as amended (the
         "Securities Act"), or any other laws or regulations, there may be legal
         restrictions or limitations affecting Secured Party in any attempts to
         dispose of certain portions of the Pledged Securities in the
         enforcement of its rights and remedies hereunder. For these reasons,
         Secured Party is hereby authorized by Debtor, but not obligated, in the
         event any Default hereunder, to sell, bid upon, and purchase all or any
         part of the Pledge Securities at private sale, subject to investment
         letter or in any other commercially reasonable manner which will not
         require the Pledged Securities, or any part thereof, to be registered
         in accordance with the Securities Act, or the rules and regulations
         promulgated thereunder, or any other law or regulation. Debtor
         acknowledges Secured Party may in its discretion approach a restricted
         number of potential purchasers and that a sale under such circumstances
         may yield a lower price of the Pledged Securities or any part or parts
         thereon than would otherwise be obtainable if same were registered and
         sold in the open market.

         8. FURTHER ASSURANCES. Debtor agrees to execute such stock powers and
assignments, endorse such instruments, or execute such additional pledge
agreements or other documents as may be reasonably requested by Secured Party in
order effectively to grant to

                                       -3-
<PAGE>   4


Secured Party the Security Interest in (and pledge and assignment of) the
Pledged Securities and to enforce and exercise Secured Party's rights regarding
same.

         9. ASSIGNABILITY. The rights, powers and interests held by Secured
Party hereunder, together with the Pledged Securities, may be transferred and
assigned by Secured Party in whole or in part. This Agreement may not be
assigned, in whole or in part, by Debtor.

         10. DELIVERY OF PLEDGED SECURITIES. When the Secured Indebtedness has
been paid in full or otherwise satisfied, Secured Party shall deliver the
Pledged Securities to Debtor concurrently with its receipt of such payment or
satisfaction and this Agreement shall terminate.

         11. WAIVER OF DEFAULT. The acceptance by Secured Party at any time and
from time to time of partial payment of the aggregate amount of the Secured
Indebtedness then matured shall not be deemed to be a waiver of any Default then
existing. No waiver by Secured Party of any Default shall be deemed to be a
waiver of any subsequent Default, nor shall any such waiver by Secured Party be
deemed to be a continuing waiver. No delay or omission by Secured Party in
exercising any right or power hereunder, except for the failure by Secured Party
to give notice as provided herein or in the Note or under any other writings
executed by Debtor as security for or in connection with the Note or the Secured
Indebtedness, shall impair such right or power or be construed as a waiver
thereof or any acquiescence therein, nor shall any single or partial exercise of
any such right or power preclude other or further exercise of any other right or

                                 PROMISSORY NOTE



$300,000.00                                                     December 1, 1999

     FOR VALUE RECEIVED, the undersigned, Jeffrey S. Doss ("Maker"), promises to
pay to the order of Mobility Electronics, Inc., a Delaware corporation
("Payee"), at 7955 East Redfield Road, Scottsdale, Arizona 85260 (or such other
address as Payee may advise Maker in writing), the principal sum of THREE
HUNDRED THOUSAND AND 00/100 DOLLARS ($300,000.00), in lawful currency of the
United States of America, together with interest accrued thereon (calculated on
the basis of a 365-day year) at a rate of 6% per annum from the date hereof
until this Note is paid in full.

         1. Payments. The entire principal balance of, and accrued interest on,
this Note is due and payable in full on December 1, 2001; provided, however,
that the following payments must be made prior to such date: (i) Payee shall
make an interest and principal payment (accrued but unpaid interest first)
within five (5) days after receiving any bonus from Maker, which payment shall
be in an amount equal to the after-tax amount of such bonus; and (ii) upon the
sale of any Pledged Securities (as defined in that certain Pledge Agreement, of
even date herewith, by and between Payee and Maker (the "Pledge Agreement")),
Maker shall make an interest and principal payment (accrued but unpaid interest
first) within five (5) days after such sale, which payment shall be in an amount
equal to the after-tax amount of the proceeds from such sale.

         2. Optional Prepayment. Maker may at its sole option prepay all or any
part of the principal of this Note, or interest thereon, before maturity without
penalty or premium. All such prepayments shall first be applied to accrued
interest under this Note, and the remaining balance of any such prepayments, if
any, shall be applied to principal of this Note.

         3. Security. This Note is secured by a security interest in the Pledged
Securities under the Pledge Agreement. Payee shall be entitled to all benefits
of the remedies and security set forth in the Pledge Agreement.

         4. Events of Default and Remedies. At the option of Payee the entire
principal balance of, together with all accrued and unpaid interest on, this
Note shall at once become due and payable, without further notice or demand,
upon the occurrence at any time of any of the following events of default
("Events of Default"):

                  (i) Failure of Maker to make any payment of principal or
interest when due hereunder, and such failure continues for a period of 2
business days after the receipt by Maker of written notice from Payee of the
occurrence of such failure; or

                  (ii) Failure of Maker to perform any covenant, agreement or
condition contained herein or in the Pledge Agreement, except the failure of
Maker to make any payment of principal

<PAGE>   2


or interest when due hereunder, and such failure continues for a period of 10
days after the receipt by Maker of written notice from Payee of the occurrence
of such failure; or

                  (iii) Maker shall (a) become insolvent, (b) voluntarily seek,
consent to, acquiesce in the benefit or benefits of any Debtor Relief Law (as
hereinafter defined) or (c) become party to (or be made the subject of) any
proceeding provided by any Debtor Relief Law, other than as a creditor or
claimant, that could suspend or otherwise adversely affect the rights of Payee
granted hereunder (unless in the event such proceeding is involuntary, the
petition instituting the same is dismissed within 90 days of the filing of
same). As used herein, the term "Debtor Relief Law" means the Bankruptcy Code of
the United States of America and all other applicable liquidation,
conservatorship, bankruptcy, moratorium, rearrangement, receivership,
insolvency, reorganization or similar debtor relief laws from time to time in
effect affecting the rights of creditors generally.

         In the event any one or more of the Events of Default specified above
shall have happened, the holder of this Note may (a) enforce its rights, if any,
under this Note and or under the Pledge Agreement and/or (b) proceed to protect
and enforce its rights either by suit in equity and/or by action at law, or by
other appropriate proceedings, whether for the specific performance of any
covenant or agreement contained in this Note or in the Pledge Agreement or in
aid of the exercise of any power or right granted by this Note or the Pledge
Agreement, or to enforce any other legal and equitable right of the holder of
this Note or in the Pledge Agreement.

         5. Waiver. Except as expressly provided herein, Maker, and each surety,
endorser, guarantor and other party ever liable for the payment of any sum of
money payable on this Note, jointly and severally waive demand, presentment,
protest, notice of non-payment, notice of intention to accelerate, notice of
protest and any and all lack of due diligence or delay in collection or the
filing of suit hereon which may occur.

         6. Cumulative Rights. No delay on the part of the holder of this Note
in the exercise of any power or right under this Note shall operate as a waiver
thereof, nor shall a single or partial exercise of any other power or right.
Enforcement by the holder of this Note of any security for the payment hereof
shall not constitute any election by it of remedies so as to preclude the
exercise of any other remedy available to it.

         7. Notices. Any notice or demand given hereunder by the holder hereof
shall be deemed to have been given and received (i) when actually received by
Maker, if delivered in person or by facsimile transmission, or (ii) if mailed,
on the earlier of the date actually received or (whether ever received or not)
three Business Days (as hereinafter defined) after a letter containing such
notice, certified or registered, with postage prepaid, addressed to Maker, is
deposited in the United States mail. The address of Maker is 7955 East Redfield
Road, Scottsdale, Arizona 85260, or such other address as Maker shall advise the
holder hereof by certified or registered letter by this same procedure.
"Business Day" means every day which is not a Saturday, Sunday or legal holiday.

         8. Successors and Assigns. This Note and all covenants, promises and
agreements contained herein shall be binding upon and inure to the benefit of
the respective legal representatives, personal representatives, devisees, heirs,
successors and assigns of Payee and Maker.

         9. GOVERNING-LAW. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE. IN CASE ANY ONE OR MORE OF
THE PROVISIONS CONTAINED IN THIS NOTE SHALL FOR ANY REASON BE HELD TO BE
INVALID, ILLEGAL OR UNENFORCEABLE IN ANY RESPECT, SUCH INVALIDITY, ILLEGALITY OR
UNENFORCEABILITY SHALL NOT AFFECT ANY OTHER PROVISION HEREOF.

         10. Usury Savings Clause. Any provision in this Note or in any other
document executed in connection herewith, or in any other agreement or
commitment, whether written or oral, express or implied, to the contrary
notwithstanding, Payee shall not in any event be entitled to receive or collect,
nor shall or may amounts received hereunder be credited, so that Payee shall be
paid, as interest, a sum greater than the maximum rate of interest permitted by
applicable law. If any construction of this Note, or any and all other papers,
agreements or commitments, indicates a different right given to Payee to ask
for, demand or receive any larger sum as interest, such is a mistake in
calculation or wording, which this clause shall override and control; it being
the intention of the parties that this Note and all other instruments relating
to this Note shall in all things comply with applicable law, and proper
adjustment shall automatically be made accordingly. In the event Payee ever
receives, collects or applies as interest, any sum in excess of the maximum rate
of interest permitted by applicable law, such excess amount shall be applied to
the reduction of the unpaid principal balance of this Note in the inverse order
of maturity, and if this Note is paid in full, any remaining excess shall be
paid to Maker. In determining whether or not the interest paid or payable, under
any specific contingency, exceeds the maximum rate of interest permitted by
applicable law, Maker and Payee shall, the maximum extent permitted under
applicable law (i) characterize any nonprincipal payment as an expense, fee or
premium rather than as interest, (ii) exclude voluntary prepayments and the
effects thereof, and (iii) "spread" the total amount of interest throughout the
entire term of this Note so that the interest rate is uniform throughout the
entire term hereof.

         11. Attorneys' Fees and Costs. In the event an Event of Default shall
occur, and in the event that thereafter this Note is placed in the hands of an
attorney for collection, or in the event this Note is collected in whole or in
part through legal proceedings of any nature, then and in any such case Maker
promises to pay all costs of collection, including, but not limited to,
reasonable attorneys' fees incurred by the holder hereof on account of such
collection, whether or not suit is filed.

         12. Headings. The headings of the sections of this Note are inserted
for convenience only and shall not be deemed to constitute a part hereof.

                              CONSULTING AGREEMENT


         THIS CONSULTING AGREEMENT (the "Agreement") is made and entered into as
of the 21st day of May, 1999, by and between Mobility Electronics, Inc., a
Delaware corporation (the "Company"), and Robert Dilworth ("Consultant").

                              W I T N E S S E T H:

         WHEREAS, the Company desires to retain Consultant as provided herein,
and Consultant desires to be so retained; and

         WHEREAS, Consultant shall, as a consultant to the Company, have access
to confidential information with respect to the Company;

         NOW, THEREFORE, for and in consideration of the mutual covenants and
agreements contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties hereto
hereby agree as follows:

         1. DUTIES. Consultant is hereby retained to serve as a consultant to
the Company to perform such services and render such advice to the Company as
the Chief Executive Officer of the Company may from time to time reasonably
request (collectively, the "Duties"); provided, however, that in no month shall
such services exceed an aggregate of sixteen (16) hours, without the consent of
Consultant.

         2. TERM. The term of this Agreement shall commence on the date hereof
and shall be for a period of two (2) years (the "Term"); provided, however, that
this Agreement may be terminated by either party hereto at any time upon at
least thirty (30) days prior written notice to the other party.

         3. COMPENSATION. As compensation for rendering the Duties, the Company
shall grant Consultant options to purchase 70,000 shares of the Company's common
stock, par value $.01 per share, on the terms and conditions to be set forth in
that certain Nonqualified Stock Option Agreement of the Company, a copy of which
is attached hereto as Exhibit A. Additionally, during the Term, the Company
shall reimburse Consultant for all reasonable and necessary out-of-pocket travel
and other expenses incurred by Consultant in performing the Duties, such
reimbursement to be on a monthly basis, within thirty (30) days after submission
of a detailed monthly statement and reasonable supporting documentation. The
compensation set forth in this Section 3 will be the sole compensation payable
to Consultant for performing the Duties, and no additional compensation or fee
will be payable by the Company to Consultant by reason of any benefit gained by
the Company directly or indirectly through Consultant's performing the Duties,
nor shall the Company be liable


                                      -1-
<PAGE>   2

in any way for any additional compensation or fee for performing the Duties
unless the Company shall have expressly agreed thereto in writing.

         4. INDEPENDENT CONTRACTOR STATUS. The Company and Consultant agree that
Consultant is an independent contractor under this Agreement and shall in no way
be considered to be an agent or employee of the Company and, accordingly,
Consultant shall not be entitled to any benefits, coverages or privileges made
available to employees of the Company, including without limitation, social
security, unemployment, medical or pension payments. Consultant shall only
consult and render advice, and shall not undertake to commit the Company to any
course of action in relation to third persons, except as requested in writing by
the Company. The Company shall not deduct any social security or income taxes
from Consultant's payments set forth in Section 3.

         5. CONFIDENTIALITY.

         (a) ACKNOWLEDGMENT OF PROPRIETARY INTEREST. Consultant recognizes the
proprietary interest of the Company in any Confidential and Proprietary
Information (as hereinafter defined) of the Company. Consultant acknowledges and
agrees that any and all Confidential and Proprietary Information communicated
to, learned of, developed or otherwise acquired by the Consultant during the
course of his engagement by the Company after the date hereof, whether developed
by Consultant alone or in conjunction with others or otherwise, shall be and is
the property of the Company. Consultant further acknowledges and understands
that his disclosure of any Confidential and Proprietary Information will result
in irreparable injury and damage to the Company. As used herein, "Confidential
and Proprietary Information" means, but is not limited to, information derived
from reports, investigations, experiments, research, work in progress, drawings,
designs, plans, proposals, codes, marketing and sales programs, client lists,
client mailing lists, financial projections, cost summaries, pricing formula,
contracts analyses, financial information, projections, maps, confidential
filings with any state or federal agency, and all other concepts, ideas,
materials or information prepared or performed for, by or on behalf of the
Company by its employees, officers, directors, agents, representatives or
consultants (including, without limitation, acquisition strategies, acquisition
candidates, acquisition contacts and proposed terms of acquisitions).

         (b) COVENANT NOT-TO-DIVULGE CONFIDENTIAL AND PROPRIETARY INFORMATION.
Consultant acknowledges and agrees that the Company is entitled to prevent the
disclosure of Confidential and Proprietary Information. As a portion of the
consideration for the retainment of Consultant and for the compensation being
paid to Consultant by the Company, Consultant agrees at all times during the
term of this Agreement and thereafter to hold in strictest confidence and not to
disclose to any person, firm or corporation, other than to persons engaged by
the Company to further the business of the Company, and not to use except in the
pursuit of the business of the Company, Confidential and Proprietary
Information, without the prior written consent of the Company, including
Confidential and Proprietary Information developed by Consultant during the
course of his engagement hereunder; provided, however, that notwithstanding the
foregoing, Consultant shall not


                                      -2-
<PAGE>   3

be obligated to keep secret and not to disclose Confidential and Proprietary
Information generally known to the public through no wrongful act of Consultant.

         (c) RETURN OF MATERIALS. In the event of any termination of this
Agreement for any reason whatsoever, or at any time upon the request of the
Company, Consultant will promptly deliver to the Company all documents, data and
other information pertaining to Confidential and Proprietary Information.
Consultant shall not take any documents or other information, or any
reproduction or excerpt thereof, containing or pertaining to any Confidential
and Proprietary Information, unless as otherwise authorized in writing by the
President of the Company.

         6. REMEDIES. Consultant recognizes and acknowledges that in the event
of any default in, or breach of any of, the terms, conditions or provisions of
this Agreement (either actual or threatened) by Consultant, the Company's
remedies at law shall be inadequate. Accordingly, Consultant agrees that in such
event, the Company shall have the right of specific performance and/or
injunctive relief in addition to any and all other remedies and rights at law or
in equity, and such rights and remedies shall be cumulative.

         7. NOTICES. Any notices, consents, demands, requests, approvals and
other communications to be given under this Agreement by either party to the
other shall be deemed to have been duly given in writing and personally
delivered or sent by facsimile or mail, registered or certified, postage prepaid
with return receipt requested, to such party's address as last provided to the
other party. Notices delivered personally shall be deemed communicated as of
actual receipt; mailed notices shall be deemed communicated as of three days
after mailing.

         8. ENTIRE AGREEMENT. This Agreement contains the entire agreement of
the parties hereto with respect to the subject matter contained herein and
supersedes all prior agreements and understandings, oral or written, between the
parties hereto with respect to the subject matter hereof. No modification or
amendment of any of the terms, conditions or provisions herein may be made
otherwise than by written agreement signed by the parties hereto.

         9. GOVERNING LAW. This agreement and the rights and obligations of the
parties hereto shall be governed, construed and enforced in accordance with the
laws of the State of Delaware (except the choice of law rules).

         10. PARTIES BOUND. This Agreement and the rights and obligations of the
parties hereto shall be binding upon and inure to the benefit of the Company and
Consultant and their respective heirs, personal representatives, successors and
assigns. No person or entity shall be deemed a third party beneficiary of this
Agreement. Consultant may not assign any of his rights, obligations or duties
hereunder without the prior written consent of the Company.

<PAGE>   4

         11. SEVERABILITY. If any provision of this Agreement is held to be
illegal, invalid or unenforceable under present or future laws effective during
the term hereof, such provision shall be fully severable and this Agreement
shall be construed and enforced as if such illegal, invalid or unenforceable
provision never comprised a part hereof; and the remaining provisions hereof
shall remain in full force and effect and shall not be affected by the illegal,
invalid or unenforceable provision or by its severance herefrom. Furthermore, in
lieu of such illegal, invalid or unenforceable provision, there shall be added
automatically as part of this Agreement a provision as similar in its terms to
such illegal, invalid or unenforceable provision as may be possible and be
legal, valid and enforceable.

         12. WAIVER OF BREACH. The waiver by any party hereto of a breach of any
provision of this Agreement shall not operate or be construed as a wavier of any
subsequent breach by any party.

         13. COSTS. If it is necessary to enforce or interpret the terms of this
Agreement by action at law or in equity, the prevailing party shall be entitled
to reasonable attorneys' fees, costs and necessary disbursements in addition to
any other relief to which he or it may be entitled.

         14. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original and all of which shall
constitute one and the same instrument, but only one of which need be produced.

         IN WITNESS WHEREOF, the parties have duly executed this Agreement as of
the date first above written.

                                   AGREEMENTS

         NOW, THEREFORE, in consideration of the actual agreements herein and
other good and valuable consideration, the Borrower and the Bank hereby agree as
follows:

         1. Extension of Termination Date. The Loan Agreement is hereby amended
to provide that the Termination Date is extended until March 31, 2000, whereupon
the Bank will no longer make advances of the Loan to the Borrower or issue
Standby or Commercial Letters of Credit for the benefit of the Borrower. The
existing provisions of the Loan Agreement provide that, with certain exceptions,
any Letters of Credit issued thereunder shall have an Expiry Date no later than
the Termination Date, and the related Applications and Agreements of Letters of
Credit require the Borrower to repay on demand any Letter of Credit Obligations
arising with respect to Letters of Credit. With respect to any Letter of Credit
having an expiry date after the Termination Date, the Loan Agreement requires
that the related Letter of Credit Obligations shall be prepaid on the day
immediately preceding the Termination Date.

         2. Extension of Maturity Date. The Promissory Note is hereby amended to
provide that the maturity date is extended until March 31, 2000, whereupon all
of the Loan Obligations shall become immediately due and payable.

         3. Interest Rate Applicable to Loan. The Promissory Note is hereby
amended to provide for the increase in the interest rate applicable to the Loan
from the Prime Rate plus 1 1/2% to the Primate Rate plus 2 1/2%. For purposes of
accomplishing this objective, clause (a) of the Promissory Note is hereby
deleted in its entirety and replaced with the following clause (a):

                  "(a) interest on the unpaid principal balance at an annual
         rate, which is equal to the fluctuating prime rate of interest
         established and declared by the Bank from time to time (the "Prime
         Rate") plus two and one-half percent per annum (2 1/2%), shall be due
         and payable on the first calendar day of each and every month after the
         date hereof until the principal sum is paid in full; and"

         4. Financial Covenant Revisions. (a) Sections 9.1 and 9.2 of the Loan
Agreement are hereby deleted in their entirety and replaced with the following
Sections 9.1 and 9.2:

                  "9.1 Current Ratio. The Borrowers shall maintain a ratio of
         Current Assets to Current Liabilities of not less than 0.9 to 1.0."

                  "9.2 Tangible Net Worth. The Borrower shall maintain a
         Tangible Net Worth of not less than (i) ($1,800,000) at October 31,
         1999, (ii) ($2,600,000) at November 30, 1999, and (iii) ($3,400,000) at
         December 31, 1999, and at all times thereafter."

<PAGE>   3

                  (b) In addition, the following financial covenant is hereby
         added to the Loan Agreement as new Section 9.4:

                  "9.4 Capital Expenditures. The Borrower will not make any
         capital expenditures exceeding, in the aggregate during any one fiscal
         year, the total sum of $900,000."

         5. Financial Reporting. Section 8.1(c) of the Loan Agreement is hereby
revised to require that (a) the Borrowing Base Certificates be provided twice
per month by the 15th and 30th of each month and (b) the reports on the
Borrower's Receivables and Inventory and export purchase orders be provided no
later than the 15th day of each calendar month.

         6. Conditions Precedent. It is a condition precedent to the
effectiveness of this Amendment that (a) the Bank receive EXIMBANK's consent to
the extension of the Termination Date and the maturity date for the Borrower's
Obligations in respect of the EXIMBANK Guaranty, and (b) the Borrower execute
and deliver to the Bank the EXIMBANK Borrower Agreement in the form attached
hereto as EXHIBIT A, as required by EXIMBANK.

         7. EXIMBANK COUNTY LIMITATION SCHEDULE. For purposes of facilitating
the Borrower's compliance with Section 5.3 of the Loan Agreement containing
Collateral Value requirements, a copy of EXIMBANK's current Country Limitation
Schedule is attached to this amendment as EXHIBIT B. This Schedule is revised,
amended and updated periodically, and the Bank will endeavor to provide the
Borrower with copies of any supplements and modifications to the Country
Limitation Schedule which are provided to it by EXIMBANK.

         8. No Other Amendments. Except as specifically contemplated herein, the
Loan Agreement, the Promissory Note and all of the other Financing Documents
shall remain in full force and effect in accordance with their respective terms.

         9. Bank's Rights Reaffirmed. The Bank shall continue to have all rights
and remedies set forth in the Loan Agreement, the Promissory Note and all of the
other Financing Documents, including but not limited to the right to accelerate
the Termination Date and the right to accelerate the Borrower's Obligations as
set forth in Section 11.2 of the Loan Agreement, and the right to demand
repayment of the Borrower's Obligations in accordance with the terms of the
Promissory Note.

amount of $4,687.50 relating to the extension of the Termination Date and the
maturity date of the Promissory Note pursuant to this Amendment.

                  (b) The Borrower must also pay all costs (including legal
fees) incurred by the Bank in connection with the preparation of this Amendment.

         11. Effectiveness. Assuming satisfaction of the conditions precedent
described in Section 3, this Amendment shall be deemed to be retroactively
effective as of October 30, 1999, regardless of the date on which it is executed
and delivered by the parties hereto.

         12. Representations and Warranties. The Borrower hereby reaffirms all
representations and warranties made by them in the Loan Agreement and in the
other Financing Documents.

         13. Governing Law. This Amendment shall be construed in accordance with
and governed by the laws of the State of New Mexico.

         14. Counterparts. This Amendment may be executed in any number of
counterparts, each of which shall be considered an original for all purposes;
provided, however, that all such counterparts shall together constitute one and
the same instrument.

         15. No Novation. The parties hereto covenant and agree that the
execution of this Amendment is not intended to and shall not cause or result in
a novation with respect to the Borrower's Obligations or the Financing Documents
and that the existing Borrower's Obligations, as evidenced by the Financing
Documents are continuing, without interruption, and have not been discharged by
a new agreement.

         IN WITNESS WHEREOF, the parties hereby have caused this Amendment to be

         (i)      the Loan Documents, including Agreement (including any
                  renewals, extensions or modifications of this Agreement, or
                  the other Loan Documents);

         (ii)     any document, agreement or procedure related to or delivered
                  in connection with this Agreement, or the other Loan
                  Documents;

         (iii)    any violation of this Agreement, or the other Loan Documents;
                  or

         (iv)     any claims for damages form any business conducted between

                  business interests (torts).

(b)      At the request of Borrower, guarantor or Bank any such controversies or
         claims will be settled by arbitration in accordance with the United
         States Arbitration Act. The United States Arbitration Act will apply
         even though this Agreement and the other Loan Documents provide that
         they are governed by Arizona law.

(c)      Arbitration proceedings will be administered by the American
         Arbitration Association and will be subject to its commercial rules of
         arbitration.

(d)      For purposes of the application of the statute of limitations, the
         filing of an arbitration pursuant to this Section is the equivalent of
         the filing of a lawsuit, and any claim or controversy which may be
         arbitrated under this Section is subject to any applicable statute of
         limitations. The arbitrators will have the authority to decide whether
         any such claim or controversy is barred by the statute of limitations
         and, if so, to dismiss the arbitration on that basis.

(e)      If there is a dispute as to whether an issue is arbitrable, the
         arbitrators will have the authority to resolve any such dispute.

         submitted to any authorized court of law to be confirmed and enforced.

         claim, at the time of the proposed submission to arbitration, arises
         from or relates to an obligation to Bank secured by residential real
         property located in Arizona. In this case, Borrower, guarantor and Bank
         must consent to submission of claim or controversy to arbitration. For
         the purposes of this Section, "residential real property" means real
         property of two and one-half acres or less which is limited to and
         utilized for either a single one-family or a single two-family
         dwelling.

(h)      This provision does not limit the right of Borrower, guarantor or Bank
         to:

         (i)      exercise self-help remedies such as setoff;

         (ii)     foreclose against or sell any real or personal property
                  collateral; or

<PAGE>   24

         (iii)    act in a court of law, before, during or after the arbitration
                  proceeding to obtain:

                  (A)      a provisional or interim remedy; and/or

                  (B)      additional or supplementary remedies.


(i)      The pursuit of or a successful action for provisional, interim,
         additional or supplementary remedies, or the filing of a court action,
         does not constitute a waiver of the right of Borrower, guarantor or
         Bank, including the suing party, to submit the controversy or claim to
         arbitration if the other party contests the lawsuit. However, if the
         controversy or claim arises from or relates to an obligation to Bank
         which is secured by residential real property located in Arizona at the
         time of the proposed submission to arbitration, this right is limited
         according to the provision above requiring the consent of both
         Borrower, guarantor and Bank to seek resolution through arbitration.

(j)      If Bank forecloses against any real property securing the Loan, Bank
         has the option to exercise the power of sale under the deed of trust or
         mortgage, or to proceed by judicial foreclosures.

                            RESTATED PROMISSORY NOTE


$3,000,000                 November 2nd 1999
                           Phoenix, Arizona

Interest Rate:             Prime Rate plus 250
                           Basis Points (see Section 3 below).

Maturity Date:             March 31, 2000 (see Section 6 below).

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

         1. FOR VALUE RECEIVED, MOBILITY ELECTRONICS, INC., f/k/a Electronics
Accessory Specialists International, Inc. a Delaware corporation ("Borrower"),
promise(s) to pay to the order of BANK OF AMERICA N.A. successor by merger to
NationsBank, N.A., (the "Bank"), at Bank's Home Office in Phoenix, Arizona, or
at such other place as Bank may from time to time designate, the principal sum
of Three Million Dollars ($3,000,000), plus interest thereon from the date of
the respective advances until paid. This Restated Promissory Note (this "Note")
evidences a loan (the "Loan") from Bank to Borrower pursuant to that certain
Loan Agreement dated January 13, 1998, as amended pursuant to that certain
Amended and Restated Business Loan Agreement (the "Modification Agreement")
dated of even date herewith (as amended, the "Loan Agreement").

         2. This Note is secured by a Security Agreement dated of even date
herewith, a Pledge of Certificate of Deposit ($150,000) dated of even date
herewith, a Pledge of Certificate of Deposit ($75,000) dated of even date
herewith, and a Patent Collateral Assignment and Security Agreement dated of
even date herewith, (collectively, the "Security Documents"), covering certain
property as therein described (the "Property"). It may also be secured by other
collateral. This Note and the Security Documents are among several Loan
Documents, as defined and designated in the Loan Agreement, between Bank and
Borrower and several guarantors. Some or all of the Loan Documents, including
the Extension Agreement, contain provisions for the acceleration of the maturity
of this Note.

         3. The principal sum outstanding from time to time under this Note
shall bear interest at the Prime Rate plus two hundred fifty (250) basis points
per year, as the same may change from time to time (the "Prime-based Rate"). As
used herein, the "Prime Rate" means the per annum rate of interest publicly
announced from time to time by Bank at San Francisco, California, as its Prime
Rate. The Prime Rate is set by Bank based on various factors, including its
costs and desired return, general economic conditions and other factors, and is
used as a reference point for pricing some loans. Bank may price loans to its
customers at, above, or below the Prime Rate. Any change in the Prime Rate shall
take effect at the opening of business on the day specified in the public
announcement of a change in the Prime Rate.

         4. Accrued interest shall be payable on the first day of each month in
arrears, commencing on December 1, 1999 until all obligations are paid in full.
Interest shall be calculated on the basis of a 360-day year on actual days
elapsed, which results in more interest than if a 365-day year were used.





                                       1

         5. For purposes of this Note, "interest" shall include any and all
interest payable as provided in this Note, together with any and all sums (the

Interest at the times and in the amounts specified in such agreements.

         6. All principal and all accrued and unpaid interest and all other
amounts payable hereunder shall be due and payable no later than March 31, 2000.

         7. Borrower may prepay some or all of the principal under this Note,
without penalty or premium. All prepayments shall be applied first on late
charges and costs, if any, and then on interest then due and the remainder on
the principal balance.

         8. If Borrower fails to make any payment of principal or interest when
it is due and payable or upon the occurrence of any Event of Default as defined
hereunder, Borrower agrees to pay interest on the outstanding principal and
accrued and unpaid interest at an annual rate (the "Default Rate") of five
hundred (500) basis points in excess of the Prime-based Rate, from the date the
payment becomes due until Borrower pays in full all such amounts due under this
Note.

         9. From and after maturity of this Note, whether by acceleration or
otherwise, all sums then due and payable under this Note, including all
principal and all accrued and unpaid interest, shall bear interest until paid in
full at the Default Rate.

         10. If an "Event of Default", (as defined in the Loan Agreement)
occurs, any obligation of the holder to make advances under this Note shall
terminate, and at the holder's option, exercisable in its sole discretion, all
sums of principal and interest under this Note shall become immediately due and
payable without notice of default, presentment or demand for payment, protest or
notice of nonpayment or dishonor, or other notices or demands of any kind or
character.

         11. It shall also be an "Event of Default" under this Note if Borrower
becomes the subject of any bankruptcy or other voluntary or involuntary
proceeding, in or out of court, for the adjustment of debtor-creditor
relationships ("Insolvency Proceeding"). If that happens all sums of principal
and interest under this Note shall automatically become immediately due and
payable without notice of default, presentment or demand for payment, protest or
notice of nonpayment or dishonor, or other notices or demands of any kind or
character.

         12. All amounts payable under this Note are payable in lawful money of
the United States during normal business hours on a Banking Day, as defined
below. Checks constitute payment only when collected.

         13. If any lawsuit or arbitration is commenced which arises out of or
relates to this Note, the Loan Documents or the Loan, the prevailing party shall
be entitled to recover from each other party such sums as the court (but not the
jury) or arbitrator may adjudge to be reasonable attorneys' fees in the action
or arbitration, in addition to costs and expenses otherwise allowed by law. In
all other situations, including any matter arising out of or relating to any
Insolvency Proceeding, Borrower agrees to pay all of Bank's costs and expenses,
including attorneys' fees, which may be incurred in enforcing or protecting
Bank's rights or interests. From the time(s) incurred until paid in full to
Bank, all such sums shall bear interest at the Default Rate.

         14. Whenever Borrower is obligated to pay or reimburse Bank for any
attorneys' fees, those fees shall include the allocated costs for services of
in-house counsel.

         15. This Note is governed by the laws of the State of Arizona, without
regard to the choice of law rules of that State.

         16. Borrower agrees that the holder of this Note may accept additional
or substitute security for this Note, or release any security or any party
liable for this Note, or extend or renew this Note, all without notice to
Borrower and without affecting the liability of Borrower.

         17. If Bank delays in exercising or fails to exercise any of its rights
under this Note, that delay or failure shall not constitute a waiver of any of
Bank's rights, or of any breach, default or failure of condition of or under
this Note. No waiver by Bank of any of its rights, or of any such breach,
default or failure of condition shall be effective, unless the waiver is
expressly stated in a writing signed by Bank. All of Bank's remedies in
connection with this Note, or any of the other Loan Documents or under
applicable law shall be cumulative, and Bank's exercise of any one or more of
those remedies shall not constitute an election of remedies.

         18. This Note inures to and binds the heirs, personal representatives,
successors and assigns of Borrower and Bank; provided, however, that Borrower
may not assign this Note or any Loan funds, or assign or delegate any of its
rights or obligations without the prior written consent of Bank in each
instance. Bank in its sole discretion may transfer this Note, and may sell or
assign participations or other interests in all or part of the Loan, on the
terms and subject to the conditions of the Loan Documents, all without notice to
or the consent of Borrower. Also without notice to or the consent of Borrower,
Bank may disclose to any actual or prospective purchaser of any securities
issued or to be issued by Bank, and to any actual or prospective purchaser or
assignee of any participation or other interest in this Note, the Loan or any
other loans made by Bank to Borrower (whether evidenced by this Note or
otherwise), any financial or other information, data or material in Bank's
possession relating to Borrower, the Loan or the Property, including any
improvements on it. If Bank so requests, Borrower shall sign and deliver a new
note to be issued in exchange for this Note.

         19. As used in this Note, the terms "Bank", "holder" and "holder of
this Note" are interchangeable. As used in this Note, the word "include(s)"
means "include(s), without limitation", and the word "including" means
"including, but not limited to." The term "Banking Day" is defined to mean a day
other than a Saturday or Sunday, on which Bank is open for business in Phoenix,
Arizona.

         20. If more than one person or entity are signing this Note as
Borrower, their obligations under this Note shall be joint and several.

         21. Each periodic payment shall be credited first on late charges and
costs of collection, if any, and then on interest then due and the remainder on
principal, and interest shall thereupon cease upon the principal so credited.

         22. Time is of the essence of each and every obligation set forth
herein, including without limitation, payment.

         23. The makers, endorsers, and guarantors of this Note jointly and
severally waive diligence, demand, presentment for payment, protest, notice of
non-payment and of protest, notice of default, notice of acceleration and all
other notices or demands of any kind. They jointly and severally consent,
without notice to them and without release of their liability to extensions and
accommodations given by the holder of this Note, the release notifications and
exchanges of any security, and to release, in whole or in part, of any other
maker, endorser or guarantor, and they each agree to make payment without the
prior consent by the holder to any security or against any other maker, endorser
or guarantor.

         24. This Note modifies, restates and replaces that certain Promissory
Note dated January 13, 1998 in the original principal amount of Four Million
Five Hundred Thousand Dollars ($4,500,000), by Borrower in favor of Bank.

         25. Borrower has caused this Note to be executed by its officers, who
were duly authorized and directed to do so by a resolution of its Board of
Directors which was duly passed and adopted by the requisite number of members
of the Board at a meeting which was duly called, noticed, and held or by a duly
adopted Action by the Unanimous Written Consent of the Board of Directors.

$1,500,000                                           November 2nd 1999
                                                     Phoenix, Arizona

Interest Rate:             Prime Rate plus 350
                           Basis Points (see Section 3 below).

Maturity Date:             March  31, 2000 (see Section 6 below).

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

         1. FOR VALUE RECEIVED, MOBILITY ELECTRONICS, INC., f/k/a Electronics
Accessory Specialists International, Inc. a Delaware corporation ("Borrower"),
promise(s) to pay to the order of BANK OF AMERICA N.A. successor by merger to
NationsBank, N.A., (the "Bank"), at Bank's Home Office in Phoenix, Arizona, or
at such other place as Bank may from time to time designate, the principal sum
of One Million Five Hundred Thousand Dollars ($1,500,000), plus interest thereon
from the date of the respective advances until paid. This Promissory Note (this
"Note") evidences a loan (the "Loan") from Bank to Borrower pursuant to that
certain Amended and Restated Business Loan Agreement dated of even date herewith
(the "Loan Agreement").

         2. This Note is secured by a Security Agreement dated of even date
herewith, a Pledge of Certificate of Deposit ($150,000) dated of even date
herewith, a Pledge of Certificate of Deposit ($75,000) dated of even date
herewith, and a Patent Collateral Assignment and Security Agreement dated of
even date herewith, (collectively, the "Security Documents"), covering certain
property as therein described (the "Property"). It may also be secured by other
collateral. This Note and the Security Documents are among several Loan
Documents, as defined and designated in the Loan Agreement, between Bank and
Borrower and several guarantors. Some or all of the Loan Documents, including
the Extension Agreement, contain provisions for the acceleration of the maturity
of this Note.

         3. The principal sum outstanding from time to time under this Note
shall bear interest at the Prime Rate plus Three Hundred Fifty (350) basis
points per year, as the same may change from time to time (the "Prime-based
Rate"). As used herein, the "Prime Rate" means the per annum rate of interest
publicly announced from time to time by Bank at San Francisco, California, as
its Prime Rate. The Prime Rate is set by Bank based on various factors,
including its costs and desired return, general economic conditions and other
factors, and is used as a reference point for pricing some loans. Bank may price
loans to its customers at, above, or below the Prime Rate. Any change in the
Prime Rate shall take effect at the opening of business on the day specified in
the public announcement of a change in the Prime Rate.

         4. Borrower will pay (i) principal in the amount of $500,000 upon the
execution of this Agreement; and (ii) principal in four (4) successive monthly
installments of Eighty Three Thousand Three Hundred Thirty Three Dollars and
Thirty Three Cents ($83,333.33) plus interest commencing December 1, 1999 and on
the first day of each month thereafter through March 1, 2000. On the Facility II
Expiration Date, Borrower will repay the remaining principal balance plus any
interest then due. Each installment, when paid, will be applied first to the
payment of interest accrued. The amount of interest due, and the portion of each
installment which is applied to interest, will change from time to time if there
are changes in the Prime Rate. The balance, if any, of each installment will be
applied to the repayment of principal. If

                                       1
<PAGE>   2

the accrued interest owing exceeds the amount of any installment, Borrower will
pay the excess in addition to the installment. The excess accrued interest will
be paid on the due date of the installment.

         5. For purposes of this Note, "interest" shall include any and all
interest payable as provided in this Note, together with any and all sums (the
"Additional Interest") payable by Borrower under any existing or future
agreement between Bank and Borrower. Borrower shall pay any and all Additional
Interest at the times and in the amounts specified in such agreements.

         6. All principal and all accrued and unpaid interest and all other
amounts payable hereunder shall be due and payable no later than March 31, 2000.

         7. Borrower may prepay some or all of the principal under this Note,
without penalty or premium. All prepayments shall be applied first on late
charges and costs, if any, and then on interest then due and the remainder on
the principal balance. Any payment of principal hereunder, in monthly payments
or otherwise, may not be reborrowed by Borrower.

         8. If Borrower fails to make any payment of principal or interest when
it is due and payable or upon the occurrence of any Event of Default as defined
hereunder, Borrower agrees to pay interest on the outstanding principal and
accrued and unpaid interest at an annual rate (the "Default Rate") of five
hundred (500) basis points in excess of the Prime-based Rate, from the date the
payment becomes due until Borrower pays in full all such amounts due under this
Note.

         9. From and after maturity of this Note, whether by acceleration or
otherwise, all sums then due and payable under this Note, including all
principal and all accrued and unpaid interest, shall bear interest until paid in
full at the Default Rate.

         10. If an "Event of Default", (as defined in the Loan Agreement)
occurs, at the holder's option, exercisable in its sole discretion, all sums of
principal and interest under this Note shall become immediately due and payable
without notice of default, presentment or demand for payment, protest or notice
of nonpayment or dishonor, or other notices or demands of any kind or character.

         11. It shall also be an "Event of Default" under this Note if Borrower
becomes the subject of any bankruptcy or other voluntary or involuntary
proceeding, in or out of court, for the adjustment of debtor-creditor
relationships ("Insolvency Proceeding"). If that happens all sums of principal
and interest under this Note shall automatically become immediately due and
payable without notice of default, presentment or demand for payment, protest or
notice of nonpayment or dishonor, or other notices or demands of any kind or
character.

         12. All amounts payable under this Note are payable in lawful money of
the United States during normal business hours on a Banking Day, as defined
below. Checks constitute payment only when collected.

         13. If any lawsuit or arbitration is commenced which arises out of or
relates to this Note, the Loan Documents or the Loan, the prevailing party shall
be entitled to recover from each other party such sums as the court (but not the
jury) or arbitrator may adjudge to be reasonable attorneys' fees in the action
or arbitration, in addition to costs and expenses otherwise allowed by law. In
all other situations, including any matter arising out of or relating to any
Insolvency Proceeding, Borrower agrees to pay all of Bank's costs and expenses,
including attorneys' fees, which may be incurred in enforcing or protecting
Bank's rights or interests. From the time(s) incurred until paid in full to
Bank, all such sums shall bear interest at the Default Rate.

         14. Whenever Borrower is obligated to pay or reimburse Bank for any
attorneys' fees, those fees shall include the allocated costs for services of
in-house counsel.

         15. This Note is governed by the laws of the State of Arizona, without
regard to the choice of law rules of that State.

or substitute security for this Note, or release any security or any party
liable for this Note, or extend or renew this Note, all without notice to
Borrower and without affecting the liability of Borrower.

         17. If Bank delays in exercising or fails to exercise any of its rights
under this Note, that delay or failure shall not constitute a waiver of any of
Bank's rights, or of any breach, default or failure of condition of or under
this Note. No waiver by Bank of any of its rights, or of any such breach,
default or failure of condition shall be effective, unless the waiver is
expressly stated in a writing signed by Bank. All of Bank's remedies in
connection with this Note, or any of the other Loan Documents or under
applicable law shall be cumulative, and Bank's exercise of any one or more of
those remedies shall not constitute an election of remedies.

         18. This Note inures to and binds the heirs, personal representatives,
successors and assigns of Borrower and Bank; provided, however, that Borrower
may not assign this Note or any Loan funds, or assign or delegate any of its
rights or obligations without the prior written consent of Bank in each
instance. Bank in its sole discretion may transfer this Note, and may sell or
assign participations or other interests in all or part of the Loan, on the
terms and subject to the conditions of the Loan Documents, all without notice to
or the consent of Borrower. Also without notice to or the consent of Borrower,
Bank may disclose to any actual or prospective purchaser of any securities
issued or to be issued by Bank, and to any actual or prospective purchaser or
assignee of any participation or other interest in this Note, the Loan or any
other loans made by Bank to Borrower (whether evidenced by this Note or
otherwise), any financial or other information, data or material in Bank's
possession relating to Borrower, the Loan or the Property, including any
improvements on it. If Bank so requests, Borrower shall sign and deliver a new
note to be issued in exchange for this Note.

         19. As used in this Note, the terms "Bank", "holder" and "holder of
this Note" are interchangeable. As used in this Note, the word "include(s)"
means "include(s), without limitation", and the word "including" means
"including, but not limited to." The term "Banking Day" is defined to mean a day

attorneys' fees, those fees shall include the allocated costs for services of
in-house counsel.

         15. This Note is governed by the laws of the State of Arizona, without
regard to the choice of law rules of that State.

         16. Borrower agrees that the holder of this Note may accept additional

         17. If Bank delays in exercising or fails to exercise any of its rights
under this Note, that delay or failure shall not constitute a waiver of any of
Bank's rights, or of any breach, default or failure of condition of or under
this Note. No waiver by Bank of any of its rights, or of any such breach,
default or failure of condition shall be effective, unless the waiver is
expressly stated in a writing signed by Bank. All of Bank's remedies in
connection with this Note, or any of the other Loan Documents or under
applicable law shall be cumulative, and Bank's exercise of any one or more of
those remedies shall not constitute an election of remedies.

         18. This Note inures to and binds the heirs, personal representatives,
successors and assigns of Borrower and Bank; provided, however, that Borrower
may not assign this Note or any Loan funds, or assign or delegate any of its
rights or obligations without the prior written consent of Bank in each
instance. Bank in its sole discretion may transfer this Note, and may sell or
assign participations or other interests in all or part of the Loan, on the
terms and subject to the conditions of the Loan Documents, all without notice to
or the consent of Borrower. Also without notice to or the consent of Borrower,
Bank may disclose to any actual or prospective purchaser of any securities
issued or to be issued by Bank, and to any actual or prospective purchaser or
assignee of any participation or other interest in this Note, the Loan or any
other loans made by Bank to Borrower (whether evidenced by this Note or
otherwise), any financial or other information, data or material in Bank's
possession relating to Borrower, the Loan or the Property, including any
improvements on it. If Bank so requests, Borrower shall sign and deliver a new
note to be issued in exchange for this Note.

         19. As used in this Note, the terms "Bank", "holder" and "holder of
this Note" are interchangeable. As used in this Note, the word "include(s)"
means "include(s), without limitation", and the word "including" means
"including, but not limited to." The term "Banking Day" is defined to mean a day
other than a Saturday or Sunday, on which Bank is open for business in Phoenix,
Arizona.

         20. If more than one person or entity are signing this Note as
Borrower, their obligations under this Note shall be joint and several.

         21. Each periodic payment shall be credited first on late charges and
costs of collection, if any, and then on interest then due and the remainder on
principal, and interest shall thereupon cease upon the principal so credited.

         22. Time is of the essence of each and every obligation set forth
herein, including without limitation, payment.

         23. The makers, endorsers, and guarantors of this Note jointly and
severally waive diligence, demand, presentment for payment, protest, notice of
non-payment and of protest, notice of default, notice of acceleration and all
other notices or demands of any kind. They jointly and severally consent,
without notice to them and without release of their liability to extensions and
accommodations given by the holder of this Note, the release notifications and
exchanges of any security, and to release, in whole or in part, of any other
maker, endorser or guarantor, and they each agree to make payment without the
prior consent by the holder to any security or against any other maker, endorser
or guarantor.

         24. Borrower has caused this Note to be executed by its officers, who
were duly authorized and directed to do so by a resolution of its Board of
Directors which was duly passed and adopted by the requisite number of members
of the Board at a meeting which was duly called, noticed, and held or by a duly
adopted Action by the Unanimous Written Consent of the Board of Directors.

                                 PROMISSORY NOTE


$75,000                                  November 2, 1999
                                         Phoenix, Arizona

Interest Rate:             Prime Rate plus 250
                           Basis Points (see Section 3 below).

Maturity Date:             September 15, 2000 (see Section 6 below).

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

         1. FOR VALUE RECEIVED, MOBILITY ELECTRONICS, INC., f/k/a Electronics
Accessory Specialists International, Inc. a Delaware corporation ("Borrower"),
promise(s) to pay to the order of BANK OF AMERICA N.A. successor by merger to
NationsBank, N.A., (the "Bank"), at Bank's Home Office in Phoenix, Arizona, or
at such other place as Bank may from time to time designate, the principal sum
of Seventy Five Thousand Dollars ($75,000), plus interest thereon from the date
of the respective advances until paid. This Promissory Note (this "Note")
evidences a loan (the "Loan") from Bank to Borrower pursuant to that certain
Amended and Restated Business Loan Agreement dated of even date herewith (the
"Loan Agreement").

         2. This Note is secured by a Security Agreement dated of even date
herewith, a Pledge of Certificate of Deposit ($150,000) dated of even date
herewith, a Pledge of Certificate of Deposit ($75,000) dated of even date
herewith, and a Patent Collateral Assignment and Security Agreement,
(collectively, the "Security Documents"), covering certain property as therein
described (the "Property"). It may also be secured by other collateral. This
Note and the Security Documents are among several Loan Documents, as defined and
designated in the Loan Agreement, between Bank and Borrower and several
guarantors. Some or all of the Loan Documents, including the Extension
Agreement, contain provisions for the acceleration of the maturity of this Note.

         3. The principal sum outstanding from time to time under this Note
shall bear interest at the Prime Rate plus Two Hundred Fifty (250) basis points
per year, as the same may change from time to time (the "Prime-based Rate"). As
used herein, the "Prime Rate" means the per annum rate of interest publicly
announced from time to time by Bank at San Francisco, California, as its Prime
Rate. The Prime Rate is set by Bank based on various factors, including its
costs and desired return, general economic conditions and other factors, and is
used as a reference point for pricing some loans. Bank may price loans to its
customers at, above, or below the Prime Rate. Any change in the Prime Rate shall
take effect at the opening of business on the day specified in the public
announcement of a change in the Prime Rate.

         4. Accrued interest shall be payable on the first day of each month in
arrears, commencing on the first day of the first calendar month following the
date that the beneficiary of that certain letter of credit in the amount of
$150,000 (as described in the Loan Agreement) draws upon such letter of credit
and on the first day of each calendar month thereafter through its Maturity
Date. Interest shall be calculated on the basis of a 360-day year on actual days
elapsed, which results in more interest than if a 365-day year were used.

                                       1

<PAGE>   2



         5. For purposes of this Note, "interest" shall include any and all
interest payable as provided in this Note, together with any and all sums (the
"Additional Interest") payable by Borrower under any existing or future
agreement between Bank and Borrower. Borrower shall pay any and all Additional
Interest at the times and in the amounts specified in such agreements.

         6. All principal and all accrued and unpaid interest and all other
amounts payable hereunder shall be due and payable no later than September 15,
2000 ("Maturity Date").

         7. Borrower may prepay some or all of the principal under this Note,
without penalty or premium. All prepayments shall be applied first on late
charges and costs, if any, and then on interest then due and the remainder on
the principal balance. Any payment of principal hereunder, in monthly payments
or otherwise, may not be reborrowed by Borrower.

         8. If Borrower fails to make any payment of principal or interest when
it is due and payable or upon the occurrence of any Event of Default as defined
hereunder, Borrower agrees to pay interest on the outstanding principal and
accrued and unpaid interest at an annual rate (the "Default Rate") of five
hundred (500) basis points in excess of the Prime-based Rate, from the date the
payment becomes due until Borrower pays in full all such amounts due under this
Note.

         9. From and after maturity of this Note, whether by acceleration or
otherwise, all sums then due and payable under this Note, including all
principal and all accrued and unpaid interest, shall bear interest until paid in
full at the Default Rate.

         10. If an "Event of Default", (as defined in the Loan Agreement)
occurs, at the holder's option, exercisable in its sole discretion, all sums of
principal and interest under this Note shall become immediately due and payable
without notice of default, presentment or demand for payment, protest or notice
of nonpayment or dishonor, or other notices or demands of any kind or character.

         11. It shall also be an "Event of Default" under this Note if Borrower
becomes the subject of any bankruptcy or other voluntary or involuntary
proceeding, in or out of court, for the adjustment of debtor-creditor
relationships ("Insolvency Proceeding"). If that happens all sums of principal
and interest under this Note shall automatically become immediately due and
payable without notice of default, presentment or demand for payment, protest or
notice of nonpayment or dishonor, or other notices or demands of any kind or
character.

         12. All amounts payable under this Note are payable in lawful money of
the United States during normal business hours on a Banking Day, as defined
below. Checks constitute payment only when collected.

         13. If any lawsuit or arbitration is commenced which arises out of or
relates to this Note, the Loan Documents or the Loan, the prevailing party shall
be entitled to recover from each other party such sums as the court (but not the
jury) or arbitrator may adjudge to be reasonable attorneys' fees in the action
or arbitration, in addition to costs and expenses otherwise allowed by law. In
all other situations, including any matter arising out of or relating to any
Insolvency Proceeding, Borrower agrees to pay all of Bank's costs and expenses,
including attorneys' fees, which may be incurred in enforcing or protecting
Bank's rights or interests. From the time(s) incurred until paid in full to
Bank, all such sums shall bear interest at the Default Rate.

         14. Whenever Borrower is obligated to pay or reimburse Bank for any
attorneys' fees, those fees shall include the allocated costs for services of
in-house counsel.

         15. This Note is governed by the laws of the State of Arizona, without
regard to the choice of law rules of that State.

         16. Borrower agrees that the holder of this Note may accept additional
or substitute security for this Note, or release any security or any party
liable for this Note, or extend or renew this Note, all without notice to
Borrower and without affecting the liability of Borrower.


                                       2

<PAGE>   3

         17. If Bank delays in exercising or fails to exercise any of its rights
under this Note, that delay or failure shall not constitute a waiver of any of
Bank's rights, or of any breach, default or failure of condition of or under
this Note. No waiver by Bank of any of its rights, or of any such breach,
default or failure of condition shall be effective, unless the waiver is
expressly stated in a writing signed by Bank. All of Bank's remedies in
connection with this Note, or any of the other Loan Documents or under
applicable law shall be cumulative, and Bank's exercise of any one or more of
those remedies shall not constitute an election of remedies.

         18. This Note inures to and binds the heirs, personal representatives,
successors and assigns of Borrower and Bank; provided, however, that Borrower
may not assign this Note or any Loan funds, or assign or delegate any of its
rights or obligations without the prior written consent of Bank in each
instance. Bank in its sole discretion may transfer this Note, and may sell or
assign participations or other interests in all or part of the Loan, on the
terms and subject to the conditions of the Loan Documents, all without notice to
or the consent of Borrower. Also without notice to or the consent of Borrower,
Bank may disclose to any actual or prospective purchaser of any securities
issued or to be issued by Bank, and to any actual or prospective purchaser or
assignee of any participation or other interest in this Note, the Loan or any
other loans made by Bank to Borrower (whether evidenced by this Note or
otherwise), any financial or other information, data or material in Bank's
possession relating to Borrower, the Loan or the Property, including any
improvements on it. If Bank so requests, Borrower shall sign and deliver a new
note to be issued in exchange for this Note.

         19. As used in this Note, the terms "Bank", "holder" and "holder of
this Note" are interchangeable. As used in this Note, the word "include(s)"
means "include(s), without limitation", and the word "including" means
"including, but not limited to." The term "Banking Day" is defined to mean a day
other than a Saturday or Sunday, on which Bank is open for business in Phoenix,
Arizona.

         20. If more than one person or entity are signing this Note as
Borrower, their obligations under this Note shall be joint and several.

         21. Each periodic payment shall be credited first on late charges and
costs of collection, if any, and then on interest then due and the remainder on
principal, and interest shall thereupon cease upon the principal so credited.

         22. Time is of the essence of each and every obligation set forth
herein, including without limitation, payment.

         23. The makers, endorsers, and guarantors of this Note jointly and

non-payment and of protest, notice of default, notice of acceleration and all

                          RESTATED CONTINUING GUARANTY
                                    (BREEZE)


To:      BANK OF AMERICA N.A. and other
         subsidiaries or affiliates of BankAmerica Corporation

         (1) For valuable consideration, Janice Breeze ("Guarantor")
unconditionally guarantees and promises to pay to BANK OF AMERICA N.A. and any
other subsidiary or affiliate of BankAmerica Corporation (each, a "Bank") which
has extended or may hereafter extend credit to Borrower (as hereinafter
defined), or order, on demand, in lawful money of the United States, One Million
Eight Hundred Thousand Dollars ($1,800,000) of indebtedness of MOBILITY
ELECTRONICS, INC., f/k/a Electronics Accessory Specialists International, Inc. a
Delaware corporation ("Borrower") to Bank. The word "indebtedness" is used
herein in its most comprehensive sense and includes any and all advances, debts,
obligations and liabilities of Borrower or any one or more of them, heretofore,
now, or hereafter made, incurred or created, whether voluntary or involuntary
and however arising, whether direct or acquired by Bank by assignment or
succession, whether due or not due, absolute or contingent, liquidated or
unliquidated, determined or undetermined, and whether Borrower may be liable
individually or jointly with others, or whether recovery upon such indebtedness
may be or hereafter become barred by any statute of limitations, or whether such
indebtedness may be or hereafter become otherwise unenforceable. This Restated
Continuing Guaranty restates, and replaces in its entirety, that certain
Commercial Guaranty dated April 6, 1999 executed by Guarantor in favor of Bank.

         (2) The liability of Guarantor under this Guaranty (exclusive of
liability under any other guaranties executed by Guarantor) shall be limited to:
One Million Eight Hundred Thousand Dollars ($1,800,000) of: (a) the principal
amount of the indebtedness; and (b) accrued but unpaid interest. In addition to
the obligations set forth in the immediately preceding sentence, Guarantor shall
be liable for all fees, and other costs and expenses relating to or arising out
of the enforcement of any rights or remedies of Bank under this Guaranty. Bank
may permit the indebtedness of Borrower to exceed Guarantor's liability, and may
apply any amounts received from any source, other than from Guarantor, to the
unguaranteed portion of Borrower's indebtedness. This is a Continuing Guaranty
relating to any indebtedness, including that arising under successive
transactions which shall either continue the indebtedness or from time to time
renew it after it has been satisfied. Any payment by Guarantor shall not reduce
their maximum obligation hereunder, unless written notice to that effect be
actually received by Bank at or prior to the time of such payment.

         (3) The obligations hereunder are joint and several, and independent of
the obligations of Borrower, and a separate action or actions may be brought and
prosecuted against Guarantor whether action is brought against Borrower or
whether Borrower be joined in any such action or actions and regardless of
whether a trustee's sale is held under any deed of trust securing the
indebtedness or regardless of whether a judicial foreclosure sale is held if any
deed of trust securing the indebtedness is judicially foreclosed as a mortgage.
Guarantor waives the benefit of any statute of limitations affecting her
liability hereunder.

         (4) Guarantor authorizes Bank, without notice or demand and without
affecting their liability hereunder, from time to time, either before or after
revocation hereof, to (a) renew, compromise, extend, accelerate or otherwise
change the time for payment of, or otherwise change the terms of the
indebtedness or any part thereof, including increase or decrease of the rate of
interest thereon; (b) receive and hold security for the payment of this Guaranty
or the indebtedness guaranteed, and exchange, enforce, waive, release, fail to
perfect, sell, or otherwise dispose of any such security; (c) apply such
security and direct the order or manner of sale thereof as Bank in its
discretion may determine, except to the extent specifically prohibited by law;
and (d) release or substitute any one or more of the endorsers or guarantors.

         (5) Guarantor waives any right to require Bank to (a) proceed against
Borrower; (b) proceed against or exhaust any security held from Borrower; or (c)
pursue any other remedy in Bank's power whatsoever. Guarantor waives any defense
arising by reason of any disability or other defense of Borrower, or the
cessation from any cause whatsoever of the liability of Borrower, or any claim
that Guarantor's obligations exceed or are more burdensome than those of
Borrower. Guarantor waives any right of subrogation,


<PAGE>   2

reimbursement, indemnification, and contribution (contractual, statutory or
otherwise), including without limitation, any claim or right of subrogation
under the Bankruptcy Code (Title 11 of the U.S. Code) or any successor statute,
arising from the existence or performance of this Guaranty and Guarantor waives
any right to enforce any remedy which Bank now has or may hereafter have against
Borrower, and waive any benefit of, and any right to participate in, any
security now or hereafter held by Bank. Upon payment of the indebtedness in full
to the Bank and upon payment by Guarantor to Bank pursuant to this Guaranty,
Guarantor shall have full rights of subrogation against Borrower. Bank may
foreclose, either by judicial foreclosure or by exercise of power of sale, any
deed of trust securing the indebtedness, and, even though the foreclosure may
destroy or diminish Guarantor's rights against Borrower, Guarantor shall be
liable to Bank for any part of the indebtedness remaining unpaid after the
foreclosure. Guarantor waives any benefit of any statutory provision limiting
the right of Bank to recover a deficiency judgment, or to otherwise proceed,
against any person or entity obligated for payment of the indebtedness, after
any judicial foreclosure sale or trustee's sale of any collateral securing the
indebtedness including, without limitation, the benefits, if any, of Arizona
Revised Statutes Sections 12-1566, 12-1641 et seq., 33-814, 44-142 and Rule
17(f) of the Arizona Rules of Civil Procedure, except to the extent otherwise
required by law. Guarantor waives any homestead or exemption rights. Guarantor
waives all presentments, demands for performance, notices of nonperformance,
protests, notices of protest, notices of dishonor, and notices of acceptance of
this Guaranty and of the existence, creation, or incurring of new or additional
indebtedness.

         (6) Guarantor acknowledges and agrees that she shall have the sole
responsibility for obtaining from Borrower such information concerning
Borrower's financial conditions or business operations as Guarantor may require,
and that Bank has no duty at any time to disclose to Guarantor any information
relating to the business operations or financial conditions of Borrower.

         (7) In addition to Bank's rights of setoff, to secure all of
Guarantor's obligations hereunder, Guarantor assigns and grants to Bank a
security interest in all moneys, securities and other property of Guarantor now
or hereafter in the possession of Bank, and all deposit accounts of Guarantor
maintained with Bank, and all proceeds thereof. Upon default or breach of any of
Guarantor's obligations to Bank, Bank may apply any deposit account to reduce
the indebtedness, and may foreclose any collateral as provided in the Uniform
Commercial Code and in any security agreements between Bank and Guarantor.

         (8) Any obligations of Borrower to Guarantor, now or hereafter
existing, including but not limited to any obligations to Guarantor as subrogees
of Bank or resulting from Guarantor's performance under this Guaranty, are
hereby subordinated to the indebtedness. Such obligations of Borrower to
Guarantor if Bank so requests shall be enforced and performance received by
Guarantor as trustees for Bank and the proceeds thereof shall be paid over to
Bank on account of the indebtedness of Borrower to Bank, but without reducing or
affecting in any manner the liability of Guarantor under the provisions of this
Guaranty.

         (9) This Guaranty may be revoked at any time by Guarantor in respect to
future transactions, unless there is a continuing consideration as to such
transactions which Guarantor does not renounce. Such revocation shall be
effective upon actual receipt by Bank at the address shown below of written
notice of revocation. Revocation shall not affect any of Guarantor's obligations
or Bank's rights with respect to transactions which precede Bank's receipt of
such notice, regardless of whether or not the indebtedness related to such
transactions, before or after revocation, has been renewed, compromised,
extended, accelerated, or otherwise changed as to any of its terms, including
time for payment or increase or decrease of the rate of interest thereon, and
regardless of any other act or omission of Bank authorized hereunder. Revocation
by any one or more of Guarantor shall not affect any obligations of any
nonrevoking Guarantor. If this Guaranty is revoked, returned, or canceled, and
subsequently any payment or transfer of any interest in property by Borrower to
Bank is rescinded or must be returned by Bank to Borrower, this Guaranty shall
be reinstated with respect to any such payment or transfer, regardless of any
such prior revocation, return, or cancellation.

         (10) Where any one or more of Borrower are corporations or partnerships
it is not necessary for Bank to inquire into the powers of Borrower or of the
officers, directors, partners or agents acting or purporting to act on their
behalf, and any indebtedness made or created in reliance upon the professed
exercise of such powers shall be guaranteed hereunder.


                                       2

         (11) Bank may, without notice to Guarantor and without affecting
Guarantor's obligations hereunder, assign the indebtedness and this Guaranty, in
whole or in part. Guarantor agrees that Bank may disclose to any prospective
purchaser and any purchaser of all or part of the indebtedness any and all
information in Bank's possession concerning Guarantor, this Guaranty and any
security for this Guaranty.

         (12) Guarantor agrees to pay all attorneys' fees, the allocated costs
of Bank's in-house counsel, and all other costs and expenses which may be
incurred by Bank in the enforcement of this Guaranty, including without
limitation all costs and necessary disbursements in any legal action or
arbitration proceeding.

         (14) This Guaranty shall be governed by and construed according to the
laws of the State of Arizona, to the jurisdiction of which the parties hereto
submit; provided, however, this Guaranty shall be governed by New Mexico law to
the extent of application of marital interests and rights to bind property of a
Guarantor and/or his spouse.

         (15) (a) Any controversy or claim between or among the parties,
including but not limited to those arising out of or relating to this Guaranty
or any agreements or instruments relating hereto or delivered in connection
herewith and any claim based on or arising from an alleged tort, shall at the
request of any party be determined by arbitration. The arbitration shall be
conducted in accordance with the United States Arbitration Act (Title 9, U.S.
Code), notwithstanding any choice of law provision in this Guaranty, and under
the Commercial Rules of the American Arbitration Association ("AAA"). The
arbitrator(s) shall give effect to statutes of limitation in determining any
claim. Any controversy concerning whether an issue is arbitrable shall be
determined by the arbitrator(s). Judgment upon the arbitration award may be
entered in any court having jurisdiction. The institution and maintenance of an
action for judicial relief or pursuit of a provisional or ancillary remedy shall
not constitute a waiver of the right of any party, including the plaintiff, to
submit the controversy or claim to arbitration if any other party contests such
action for judicial relief.

                  (b) No provision of this paragraph shall limit the right of
any party to this Guaranty to exercise self-help remedies such as setoff, to
foreclose against or sell any real or personal property collateral or security,
or to obtain provisional or ancillary remedies from a court of competent
jurisdiction before, after, or during the pendency of any arbitration or other
proceeding. The exercise of a remedy does not waive the right of either party to
resort to arbitration. At Bank's option, foreclosure under a deed of trust or
mortgage may be accomplished either by exercise of power of sale under the deed
of trust or mortgage or by judicial foreclosure.

                          RESTATED CONTINUING GUARANTY
                                     (DOSS)


To:      BANK OF AMERICA N.A. and other
         subsidiaries or affiliates of BankAmerica Corporation

         (1) For valuable consideration, Jeffrey Doss ("Guarantor")
unconditionally guarantees and promises to pay to BANK OF AMERICA N.A. and any
other subsidiary or affiliate of BankAmerica Corporation (each, a "Bank") which
has extended or may hereafter extend credit to Borrower (as hereinafter
defined), or order, on demand, in lawful money of the United States, One Million
Eight Hundred Thousand Dollars ($1,800,000) of indebtedness of MOBILITY
ELECTRONICS, INC., f/k/a Electronics Accessory Specialists International, Inc. a
Delaware corporation ("Borrower") to Bank. The word "indebtedness" is used
herein in its most comprehensive sense and includes any and all advances, debts,
obligations and liabilities of Borrower or any one or more of them, heretofore,
now, or hereafter made, incurred or created, whether voluntary or involuntary
and however arising, whether direct or acquired by Bank by assignment or
succession, whether due or not due, absolute or contingent, liquidated or
unliquidated, determined or undetermined, and whether Borrower may be liable
individually or jointly with others, or whether recovery upon such indebtedness
may be or hereafter become barred by any statute of limitations, or whether such
indebtedness may be or hereafter become otherwise unenforceable. This Restated
Continuing Guaranty restates, and replaces in its entirety, that certain
Commercial Guaranty dated April 6, 1999 executed by Guarantor in favor of Bank.

         (2) The liability of Guarantor under this Guaranty (exclusive of
liability under any other guaranties executed by Guarantor) shall be limited to:
One Million Eight Hundred Thousand Dollars ($1,800,000) of: (a) the principal
amount of the indebtedness; and (b) accrued but unpaid interest. In addition to
the obligations set forth in the immediately preceding sentence, Guarantor shall
be liable for all fees, and other costs and expenses relating to or arising out
of the indebtedness or such part of the enforcement of any rights or remedies of
Bank under this Guaranty. Bank may permit the indebtedness of Borrower to exceed
Guarantor's liability, and may apply any amounts received from any source, other
than from Guarantor, to the unguaranteed portion of Borrower's indebtedness.
This is a Continuing Guaranty relating to any indebtedness, including that
arising under successive transactions which shall either continue the
indebtedness or from time to time renew it after it has been satisfied. Any
payment by Guarantor shall not reduce their maximum obligation hereunder, unless
written notice to that effect be actually received by Bank at or prior to the
time of such payment.

         (3) The obligations hereunder are joint and several, and independent of
the obligations of Borrower, and a separate action or actions may be brought and
prosecuted against Guarantor whether action is brought against Borrower or
whether Borrower be joined in any such action or actions and regardless of
whether a trustee's sale is held under any deed of trust securing the
indebtedness or regardless of whether a judicial foreclosure sale is held if any
deed of trust securing the indebtedness is judicially foreclosed as a mortgage.
Guarantor waives the benefit of any statute of limitations affecting his
liability hereunder.

         (4) Guarantor authorizes Bank, without notice or demand and without
affecting their liability hereunder, from time to time, either before or after
revocation hereof, to (a) renew, compromise, extend, accelerate or otherwise
change the time for payment of, or otherwise change the terms of the
indebtedness or any part thereof, including increase or decrease of the rate of
interest thereon; (b) receive and hold security for the payment of this Guaranty
or the indebtedness guaranteed, and exchange, enforce, waive, release, fail to
perfect, sell, or otherwise dispose of any such security; (c) apply such
security and direct the order or manner of sale thereof as Bank in its
discretion may determine, except to the extent specifically prohibited by law;
and (d) release or substitute any one or more of the endorsers or guarantors.

         (5) Guarantor waives any right to require Bank to (a) proceed against
Borrower; (b) proceed against or exhaust any security held from Borrower; or (c)
pursue any other remedy in Bank's power whatsoever. Guarantor waives any defense
arising by reason of any disability or other defense of Borrower, or the
cessation from any cause whatsoever of the liability of Borrower, or any claim
that Guarantor's obligations


                                       1
<PAGE>   2

exceed or are more burdensome than those of Borrower. Guarantor waives any right
of subrogation, reimbursement, indemnification, and contribution (contractual,
statutory or otherwise), including without limitation, any claim or right of
subrogation under the Bankruptcy Code (Title 11 of the U.S. Code) or any
successor statute, arising from the existence or performance of this Guaranty
and Guarantor waives any right to enforce any remedy which Bank now has or may
hereafter have against Borrower, and waive any benefit of, and any right to
participate in, any security now or hereafter held by Bank. Upon payment of the
indebtedness in full to the Bank and upon payment by Guarantor to Bank pursuant
to this Guaranty, Guarantor shall have full rights of subrogation against
Borrower. Bank may foreclose, either by judicial foreclosure or by exercise of
power of sale, any deed of trust securing the indebtedness, and, even though the
foreclosure may destroy or diminish Guarantor's rights against Borrower,
Guarantor shall be liable to Bank for any part of the indebtedness remaining
unpaid after the foreclosure. Guarantor waives any benefit of any statutory
provision limiting the right of Bank to recover a deficiency judgment, or to
otherwise proceed, against any person or entity obligated for payment of the
indebtedness, after any judicial foreclosure sale or trustee's sale of any
collateral securing the indebtedness including, without limitation, the
benefits, if any, of Arizona Revised Statutes Sections 12-1566, 12-1641 et seq.,
33-814, 44-142 and Rule 17(f) of the Arizona Rules of Civil Procedure, except to
the extent otherwise required by law. Guarantor waives any homestead or
exemption rights. Guarantor waives all presentments, demands for performance,
notices of nonperformance, protests, notices of protest, notices of dishonor,
and notices of acceptance of this Guaranty and of the existence, creation, or
incurring of new or additional indebtedness.

         (6) Guarantor acknowledges and agrees that he shall have the sole
responsibility for obtaining from Borrower such information concerning
Borrower's financial conditions or business operations as Guarantor may require,
and that Bank has no duty at any time to disclose to Guarantor any information
relating to the business operations or financial conditions of Borrower.

         (7) In addition to Bank's rights of setoff, to secure all of
Guarantor's obligations hereunder, Guarantor assigns and grants to Bank a
security interest in all moneys, securities and other property of Guarantor now
or hereafter in the possession of Bank, and all deposit accounts of Guarantor
maintained with Bank, and all proceeds thereof. Upon default or breach of any of
Guarantor's obligations to Bank, Bank may apply any deposit account to reduce
the indebtedness, and may foreclose any collateral as provided in the Uniform
Commercial Code and in any security agreements between Bank and Guarantor.

         (8) Any obligations of Borrower to Guarantor, now or hereafter
existing, including but not limited to any obligations to Guarantor as subrogees
of Bank or resulting from Guarantor's performance under this Guaranty, are
hereby subordinated to the indebtedness. Such obligations of Borrower to
Guarantor if Bank so requests shall be enforced and performance received by
Guarantor as trustees for Bank and the proceeds thereof shall be paid over to
Bank on account of the indebtedness of Borrower to Bank, but without reducing or
affecting in any manner the liability of Guarantor under the provisions of this
Guaranty.

         (9) This Guaranty may be revoked at any time by Guarantor in respect to
future transactions, unless there is a continuing consideration as to such
transactions which Guarantor does not renounce. Such revocation shall be
effective upon actual receipt by Bank at the address shown below of written
notice of revocation. Revocation shall not affect any of Guarantor's obligations
or Bank's rights with respect to transactions which precede Bank's receipt of
such notice, regardless of whether or not the indebtedness related to such
transactions, before or after revocation, has been renewed, compromised,
extended, accelerated, or otherwise changed as to any of its terms, including
time for payment or increase or decrease of the rate of interest thereon, and
regardless of any other act or omission of Bank authorized hereunder. Revocation
by any one or more of Guarantor shall not affect any obligations of any
nonrevoking Guarantor. If this Guaranty is revoked, returned, or canceled, and
subsequently any payment or transfer of any interest in property by Borrower to
Bank is rescinded or must be returned by Bank to Borrower, this Guaranty shall
be reinstated with respect to any such payment or transfer, regardless of any
such prior revocation, return, or cancellation.

         (10) Where any one or more of Borrower are corporations or partnerships
it is not necessary for Bank to inquire into the powers of Borrower or of the
officers, directors, partners or agents acting or purporting to act on their
behalf, and any indebtedness made or created in reliance upon the professed
exercise of such powers shall be guaranteed hereunder.

         (11) Bank may, without notice to Guarantor and without affecting
Guarantor's obligations hereunder, assign the indebtedness and this Guaranty, in
whole or in part. Guarantor agrees that Bank may disclose to any prospective
purchaser and any purchaser of all or part of the indebtedness any and all
information in Bank's possession concerning Guarantor, this Guaranty and any
security for this Guaranty.

         (12) Guarantor agrees to pay all attorneys' fees, the allocated costs
of Bank's in-house counsel, and all other costs and expenses which may be
incurred by Bank in the enforcement of this Guaranty, including without
limitation all costs and necessary disbursements in any legal action or
arbitration proceeding.

         (14) This Guaranty shall be governed by and construed according to the
laws of the State of Arizona, to the jurisdiction of which the parties hereto
submit; provided, however, this Guaranty shall be governed by New Mexico law to
the extent of application of marital interests and rights to bind property of a
Guarantor and/or his spouse.

         (15) (a) Any controversy or claim between or among the parties,
including but not limited to those arising out of or relating to this Guaranty
or any agreements or instruments relating hereto or delivered in connection
herewith and any claim based on or arising from an alleged tort, shall at the
request of any party be determined by arbitration. The arbitration shall be
conducted in accordance with the United States Arbitration Act (Title 9, U.S.
Code), notwithstanding any choice of law provision in this Guaranty, and under
the Commercial Rules of the American Arbitration Association ("AAA"). The
arbitrator(s) shall give effect to statutes of limitation in determining any
claim. Any controversy concerning whether an issue is arbitrable shall be
determined by the arbitrator(s). Judgment upon the arbitration award may be
entered in any court having jurisdiction. The institution and maintenance of an
action for judicial relief or pursuit of a provisional or ancillary remedy shall
not constitute a waiver of the right of any party, including the plaintiff, to
submit the controversy or claim to arbitration if any other party contests such
action for judicial relief.

                  (b) No provision of this paragraph shall limit the right of
any party to this Guaranty to exercise self-help remedies such as setoff, to
foreclose against or sell any real or personal property collateral or security,
or to obtain provisional or ancillary remedies from a court of competent
jurisdiction before, after, or during the pendency of any arbitration or other
proceeding. The exercise of a remedy does not waive the right of either party to
resort to arbitration. At Bank's option, foreclosure under a deed of trust or
mortgage may be accomplished either by exercise of power of sale under the deed
of trust or mortgage or by judicial foreclosure.

hereby subordinated to the indebtedness. Such obligations of Borrower to
Guarantor if Bank so requests shall be enforced and performance received by
Guarantor as trustees for Bank and the proceeds thereof shall be paid over to
Bank on account of the indebtedness of Borrower to Bank, but without reducing or
affecting in any manner the liability of Guarantor under the provisions of this
Guaranty.

         (9) This Guaranty may be revoked at any time by Guarantor in respect to
future transactions, unless there is a continuing consideration as to such
transactions which Guarantor does not renounce. Such revocation shall be
effective upon actual receipt by Bank at the address shown below of written
notice of revocation. Revocation shall not affect any of Guarantor's obligations
or Bank's rights with respect to transactions which precede Bank's receipt of

transactions, before or after revocation, has been renewed, compromised,
extended, accelerated, or otherwise changed as to any of its terms, including
time for payment or increase or decrease of the rate of interest thereon, and
regardless of any other act or omission of Bank authorized hereunder. Revocation
by any one or more of Guarantor shall not affect any obligations of any
nonrevoking Guarantor. If this Guaranty is revoked, returned, or canceled, and
subsequently any payment or transfer of any interest in property by Borrower to
Bank is rescinded or must be returned by Bank to Borrower, this Guaranty shall
be reinstated with respect to any such payment or transfer, regardless of any
such prior revocation, return, or cancellation.

         (10) Where any one or more of Borrower are corporations or partnerships
it is not necessary for Bank to inquire into the powers of Borrower or of the

         (11) Bank may, without notice to Guarantor and without affecting
Guarantor's obligations hereunder, assign the indebtedness and this Guaranty, in
whole or in part. Guarantor agrees that Bank may disclose to any prospective
purchaser and any purchaser of all or part of the indebtedness any and all
information in Bank's possession concerning Guarantor, this Guaranty and any
security for this Guaranty.

         (12) Guarantor agrees to pay all attorneys' fees, the allocated costs
of Bank's in-house counsel, and all other costs and expenses which may be
incurred by Bank in the enforcement of this Guaranty, including without
limitation all costs and necessary disbursements in any legal action or
arbitration proceeding.

         (14) This Guaranty shall be governed by and construed according to the
laws of the State of Arizona, to the jurisdiction of which the parties hereto
submit; provided, however, this Guaranty shall be governed by New Mexico law to
the extent of application of marital interests and rights to bind property of a
Guarantor and/or his spouse.

         (15) (a) Any controversy or claim between or among the parties,
including but not limited to those arising out of or relating to this Guaranty
or any agreements or instruments relating hereto or delivered in connection
herewith and any claim based on or arising from an alleged tort, shall at the
request of any party be determined by arbitration. The arbitration shall be
conducted in accordance with the United States Arbitration Act (Title 9, U.S.
Code), notwithstanding any choice of law provision in this Guaranty, and under
the Commercial Rules of the American Arbitration Association ("AAA"). The
arbitrator(s) shall give effect to statutes of limitation in determining any
claim. Any controversy concerning whether an issue is arbitrable shall be
determined by the arbitrator(s). Judgment upon the arbitration award may be
entered in any court having jurisdiction. The institution and maintenance of an
action for judicial relief or pursuit of a provisional or ancillary remedy shall
not constitute a waiver of the right of any party, including the plaintiff, to
submit the controversy or claim to arbitration if any other party contests such
action for judicial relief.

              (b) No provision of this paragraph shall limit the right of
any party to this Guaranty to exercise self-help remedies such as setoff, to
foreclose against or sell any real or personal property collateral or security,
or to obtain provisional or ancillary remedies from a court of competent
jurisdiction before, after, or during the pendency of any arbitration or other
proceeding. The exercise of a remedy does not waive the right of either party to
resort to arbitration. At Bank's option, foreclosure under a deed of trust or
mortgage may be accomplished either by exercise of power of sale under the deed
of trust or mortgage or by judicial foreclosure.

                          RESTATED CONTINUING GUARANTY
                                    (WILSON)


To:      BANK OF AMERICA N.A. and other
         subsidiaries or affiliates of BankAmerica Corporation

         (1) For valuable consideration, Cameron Wilson ("Guarantor")
unconditionally guarantees and promises to pay to BANK OF AMERICA N.A. and any
other subsidiary or affiliate of BankAmerica Corporation (each, a "Bank") which
has extended or may hereafter extend credit to Borrower (as hereinafter
defined), or order, on demand, in lawful money of the United States, One Million
Eight Hundred Thousand Dollars ($1,800,000) of indebtedness of MOBILITY
ELECTRONICS, INC., f/k/a Electronics Accessory Specialists International, Inc. a
Delaware corporation ("Borrower") to Bank. The word "indebtedness" is used
herein in its most comprehensive sense and includes any and all advances, debts,
obligations and liabilities of Borrower or any one or more of them, heretofore,
now, or hereafter made, incurred or created, whether voluntary or involuntary
and however arising, whether direct or acquired by Bank by assignment or
succession, whether due or not due, absolute or contingent, liquidated or
unliquidated, determined or undetermined, and whether Borrower may be liable
individually or jointly with others, or whether recovery upon such indebtedness
may be or hereafter become barred by any statute of limitations, or whether such
indebtedness may be or hereafter become otherwise unenforceable. This Restated
Continuing Guaranty restates, and replaces in its entirety, that certain
Commercial Guaranty dated April 6, 1999 executed by Guarantor in favor of Bank.

         (2) The liability of Guarantor under this Guaranty (exclusive of
liability under any other guaranties executed by Guarantor) shall be limited to:
One Million Eight Hundred Thousand Dollars ($1,800,000) of: (a) the principal
amount of the indebtedness; and (b) accrued but unpaid interest. In addition to
the obligations set forth in the immediately preceding sentence, Guarantor shall
be liable for all fees, and other costs and expenses relating to or arising out
of the enforcement of any rights or remedies of Bank under this Guaranty. Bank
may permit the indebtedness of Borrower to exceed Guarantor's liability, and may
apply any amounts received from any source, other than from Guarantor, to the
unguaranteed portion of Borrower's indebtedness. This is a Continuing Guaranty
relating to any indebtedness, including that arising under successive
transactions which shall either continue the indebtedness or from time to time
renew it after it has been satisfied. Any payment by Guarantor shall not reduce
their maximum obligation hereunder, unless written notice to that effect be
actually received by Bank at or prior to the time of such payment.

         (3) The obligations hereunder are joint and several, and independent of
the obligations of Borrower, and a separate action or actions may be brought and
prosecuted against Guarantor whether action is brought against Borrower or
whether Borrower be joined in any such action or actions and regardless of
whether a trustee's sale is held under any deed of trust securing the
indebtedness or regardless of whether a judicial foreclosure sale is held if any
deed of trust securing the indebtedness is judicially foreclosed as a mortgage.
Guarantor waives the benefit of any statute of limitations affecting his
liability hereunder.

         (4) Guarantor authorizes Bank, without notice or demand and without
affecting their liability hereunder, from time to time, either before or after
revocation hereof, to (a) renew, compromise, extend, accelerate or otherwise
change the time for payment of, or otherwise change the terms of the
indebtedness or any part thereof, including increase or decrease of the rate of
interest thereon; (b) receive and hold security for the payment of this Guaranty
or the indebtedness guaranteed, and exchange, enforce, waive, release, fail to
perfect, sell, or otherwise dispose of any such security; (c) apply such
security and direct the order or manner of sale thereof as Bank in its
discretion may determine, except to the extent specifically prohibited by law;
and (d) release or substitute any one or more of the endorsers or guarantors.

         (5) Guarantor waives any right to require Bank to (a) proceed against
Borrower; (b) proceed against or exhaust any security held from Borrower; or (c)
pursue any other remedy in Bank's power whatsoever. Guarantor waives any defense
arising by reason of any disability or other defense of Borrower, or the
cessation from any cause whatsoever of the liability of Borrower, or any claim
that Guarantor's obligations exceed or are more burdensome than those of
Borrower. Guarantor waives any right of subrogation,

                                       1

<PAGE>   2

reimbursement, indemnification, and contribution (contractual, statutory or
otherwise), including without limitation, any claim or right of subrogation
under the Bankruptcy Code (Title 11 of the U.S. Code) or any successor statute,
arising from the existence or performance of this Guaranty and Guarantor waives
any right to enforce any remedy which Bank now has or may hereafter have against
Borrower, and waive any benefit of, and any right to participate in, any
security now or hereafter held by Bank. Upon payment of the indebtedness in full
to the Bank and upon payment by Guarantor to Bank pursuant to this Guaranty,
Guarantor shall have full rights of subrogation against Borrower. Bank may
foreclose, either by judicial foreclosure or by exercise of power of sale, any
deed of trust securing the indebtedness, and, even though the foreclosure may
destroy or diminish Guarantor's rights against Borrower, Guarantor shall be
liable to Bank for any part of the indebtedness remaining unpaid after the
foreclosure. Guarantor waives any benefit of any statutory provision limiting
the right of Bank to recover a deficiency judgment, or to otherwise proceed,
against any person or entity obligated for payment of the indebtedness, after
any judicial foreclosure sale or trustee's sale of any collateral securing the
indebtedness including, without limitation, the benefits, if any, of Arizona
Revised Statutes Sections 12-1566, 12-1641 et seq., 33-814, 44-142 and Rule
17(f) of the Arizona Rules of Civil Procedure, except to the extent otherwise
required by law. Guarantor waives any homestead or exemption rights. Guarantor
waives all presentments, demands for performance, notices of nonperformance,
protests, notices of protest, notices of dishonor, and notices of acceptance of
this Guaranty and of the existence, creation, or incurring of new or additional
indebtedness.

         (6) Guarantor acknowledges and agrees that he shall have the sole
responsibility for obtaining from Borrower such information concerning
Borrower's financial conditions or business operations as Guarantor may require,
and that Bank has no duty at any time to disclose to Guarantor any information
relating to the business operations or financial conditions of Borrower.

         (7) In addition to Bank's rights of setoff, to secure all of
Guarantor's obligations hereunder, Guarantor assigns and grants to Bank a
security interest in all moneys, securities and other property of Guarantor now
or hereafter in the possession of Bank, and all deposit accounts of Guarantor
maintained with Bank, and all proceeds thereof. Upon default or breach of any of
Guarantor's obligations to Bank, Bank may apply any deposit account to reduce
the indebtedness, and may foreclose any collateral as provided in the Uniform
Commercial Code and in any security agreements between Bank and Guarantor.

         (8) Any obligations of Borrower to Guarantor, now or hereafter
existing, including but not limited to any obligations to Guarantor as subrogees
of Bank or resulting from Guarantor's performance under this Guaranty, are
hereby subordinated to the indebtedness. Such obligations of Borrower to
Guarantor if Bank so requests shall be enforced and performance received by
Guarantor as trustees for Bank and the proceeds thereof shall be paid over to
Bank on account of the indebtedness of Borrower to Bank, but without reducing or
affecting in any manner the liability of Guarantor under the provisions of this
Guaranty.

         (9) This Guaranty may be revoked at any time by Guarantor in respect to
future transactions, unless there is a continuing consideration as to such
transactions which Guarantor does not renounce. Such revocation shall be
effective upon actual receipt by Bank at the address shown below of written
notice of revocation. Revocation shall not affect any of Guarantor's obligations
or Bank's rights with respect to transactions which precede Bank's receipt of
such notice, regardless of whether or not the indebtedness related to such
transactions, before or after revocation, has been renewed, compromised,
extended, accelerated, or otherwise changed as to any of its terms, including
time for payment or increase or decrease of the rate of interest thereon, and
regardless of any other act or omission of Bank authorized hereunder. Revocation
by any one or more of Guarantor shall not affect any obligations of any
nonrevoking Guarantor. If this Guaranty is revoked, returned, or canceled, and
subsequently any payment or transfer of any interest in property by Borrower to
Bank is rescinded or must be returned by Bank to Borrower, this Guaranty shall
be reinstated with respect to any such payment or transfer, regardless of any
such prior revocation, return, or cancellation.

         (10) Where any one or more of Borrower are corporations or partnerships
it is not necessary for Bank to inquire into the powers of Borrower or of the
officers, directors, partners or agents acting or purporting to act on their
behalf, and any indebtedness made or created in reliance upon the professed
exercise of such powers shall be guaranteed hereunder.

                                       2

<PAGE>   3

         (11) Bank may, without notice to Guarantor and without affecting
Guarantor's obligations hereunder, assign the indebtedness and this Guaranty, in
whole or in part. Guarantor agrees that Bank may disclose to any prospective
purchaser and any purchaser of all or part of the indebtedness any and all
information in Bank's possession concerning Guarantor, this Guaranty and any
security for this Guaranty.

         (12) Guarantor agrees to pay all attorneys' fees, the allocated costs
of Bank's in-house counsel, and all other costs and expenses which may be
incurred by Bank in the enforcement of this Guaranty, including without
limitation all costs and necessary disbursements in any legal action or
arbitration proceeding.

         (14) This Guaranty shall be governed by and construed according to the
laws of the State of Arizona, to the jurisdiction of which the parties hereto
submit; provided, however, this Guaranty shall be governed by New Mexico law to
the extent of application of marital interests and rights to bind property of a
Guarantor and/or his spouse.

         (15) (a) Any controversy or claim between or among the parties,
including but not limited to those arising out of or relating to this Guaranty
or any agreements or instruments relating hereto or delivered in connection
herewith and any claim based on or arising from an alleged tort, shall at the
request of any party be determined by arbitration. The arbitration shall be
conducted in accordance with the United States Arbitration Act (Title 9, U.S.
Code), notwithstanding any choice of law provision in this Guaranty, and under
the Commercial Rules of the American Arbitration Association ("AAA"). The
arbitrator(s) shall give effect to statutes of limitation in determining any
claim. Any controversy concerning whether an issue is arbitrable shall be
determined by the arbitrator(s). Judgment upon the arbitration award may be
entered in any court having jurisdiction. The institution and maintenance of an
action for judicial relief or pursuit of a provisional or ancillary remedy shall
not constitute a waiver of the right of any party, including the plaintiff, to
submit the controversy or claim to arbitration if any other party contests such
action for judicial relief.

              (b) No provision of this paragraph shall limit the right of
any party to this Guaranty to exercise self-help remedies such as setoff, to
foreclose against or sell any real or personal property collateral or security,
or to obtain provisional or ancillary remedies from a court of competent
jurisdiction before, after, or during the pendency of any arbitration or other
proceeding. The exercise of a remedy does not waive the right of either party to
resort to arbitration. At Bank's option, foreclosure under a deed of trust or
mortgage may be accomplished either by exercise of power of sale under the deed
of trust or mortgage or by judicial foreclosure.

         Executed this 2nd day of November, 1999.

                             SECURED PROMISSORY NOTE

$1,750,000.00                                                     March 25, 1998

         FOR VALUE RECEIVED, the undersigned, ELECTRONICS ACCESSORY SPECIALISTS
INTERNATIONAL, INC, a Delaware corporation ("Maker"), promises to pay to the
order of SIRROM CAPITAL CORPORATION, a Tennessee corporation ("Payee"; Payee and
any subsequent holder[s] hereof are hereinafter referred to collectively as
"Holder"), at the office of Payee at P. O. Box 30378, Nashville, Tennessee
37241-0378, or at such other place as Holder may designate to Maker in writing
from time to time, the principal sum of ONE MILLION SEVEN HUNDRED FIFTY THOUSAND
AND NO/100THS DOLLARS ($1,750,000.00), together with interest on the outstanding
principal balance hereof from the date hereof at the rate of thirteen and
one-half percent (13.5%) per annum (computed on the basis of a 360-day year);
provided, however, that Holder may charge and receive interest upon any renewal
or extension hereof at the greater of (i) the rate set out above, or (ii) any
rate agreed to by the undersigned that is not in excess of the maximum rate of
interest allowed to be charged under applicable law (the "Maximum Rate") at the
time of such renewal or extension.

         Interest only on the outstanding principal balance hereof shall be due
and payable monthly, in arrears, with the first payment being payable on the
first (1st) day of April, 1998, and subsequent payments being payable on the
first (1st) day of each succeeding month thereafter until June 23, 2002 (the
"Maturity Date"), at which time the entire outstanding principal balance,
together with all accrued and unpaid interest, shall be immediately due and
payable in full.

         The indebtedness evidenced hereby may be prepaid in whole or in part,
at any time and from time to time, without penalty. Any such prepayments shall
be credited first to any accrued and unpaid interest and then to the outstanding
principal balance hereof.

         Time is of the essence of this Note. It is hereby expressly agreed that
in the event that any default be made in the payment of principal or interest as
stipulated above, which default is not cured within five (5) days; or in the
event that any default or event of default shall occur under that certain Loan
Agreement dated June 24, 1997, between Maker and Payee (as may be amended from
time to time, including on the date hereof, the "Loan Agreement"), which default
or event of default is not cured following the giving of any applicable notice
and within any applicable cure period set forth in said Loan Agreement; or
should any default by Maker be made in the performance or observance of any
covenants or conditions contained in any other instrument or document now or
hereafter evidencing, securing or otherwise relating to the indebtedness
evidenced hereby (subject to any applicable notice and cure period provisions
that may be set forth therein); then, and in such event, the entire outstanding
principal balance of the indebtedness evidenced hereby, together with any other
sums advanced hereunder, under the Loan Agreement and/or under any other


<PAGE>   2

instrument or document now or hereafter evidencing, securing or in any way
relating to the indebtedness evidenced hereby, together with all unpaid interest
accrued thereon, shall, at the option of Holder and without notice to Maker, at
once become due and payable and may be collected forthwith, regardless of the
stipulated date of maturity. Upon the occurrence of any default as set forth
herein, at the option of Holder and without notice to Maker, all accrued and
unpaid interest, if any, shall be added to the outstanding principal balance
hereof, and the entire outstanding principal balance, as so adjusted, shall bear
interest thereafter until paid at an annual rate (the "Default Rate") equal to
the lesser of (i) the rate that is seven percentage points (7.0%) in excess of
the above-specified interest rate, or (ii) the Maximum Rate in effect from time
to time, regardless of whether or not there has been an acceleration of the
payment of principal as set forth herein. All such interest shall be paid at the
time of and as a condition precedent to the curing of any such default.

         In the event this Note is placed in the hands of an attorney for
collection, or if Holder incurs any reasonable costs incident to the collection
of the indebtedness evidenced hereby, Maker and any indorsers hereof agree to
pay to Holder an amount equal to all such reasonable costs, including without
limitation all reasonable attorney's fees and all court costs.

         Presentment for payment, demand, protest and notice of demand, protest
and nonpayment are hereby waived by Maker and all other parties hereto. No
failure to accelerate the indebtedness evidenced hereby by reason of default
hereunder, acceptance of a past-due installment or other indulgences granted
from time to time, shall be construed as a novation of this Note or as a waiver
of such right of acceleration or of the right of Holder thereafter to insist
upon strict compliance with the terms of this Note or to prevent the exercise of
such right of acceleration or any other right granted hereunder or by applicable
laws. No extension of the time for payment of the indebtedness evidenced hereby
or any installment due hereunder, made by agreement with any person now or
hereafter liable for payment of the indebtedness evidenced hereby, shall operate
to release, discharge, modify, change or affect the original liability of Maker
hereunder or that of any other person now or hereafter liable for payment of the
indebtedness evidenced hereby, either in whole or in part, unless Holder agrees
otherwise in writing. This Note may not be changed orally, but only by an
agreement in writing signed by the party against whom


                                       2

<PAGE>   3

enforcement of any waiver, change, modification or discharge is sought.

         The indebtedness and other obligations evidenced by this Note are
further evidenced by (i) the Loan Agreement and (ii) certain other instruments
and documents, as may be required to protect and preserve the rights of Maker
and Payee as more specifically described in the Loan Agreement.

         All agreements herein made are expressly limited so that in no event
whatsoever, whether by reason of advancement of proceeds hereof, acceleration of
maturity of the unpaid balance hereof or otherwise, shall the amount paid or
agreed to be paid to Holder for the use of the money advanced or to be advanced
hereunder exceed the Maximum Rate. If, from any circumstances whatsoever, the
fulfillment of any provision of this Note or any other agreement or instrument
now or hereafter evidencing, securing or in any way relating to the indebtedness
evidenced hereby shall involve the payment of interest in excess of the Maximum
Rate, then, ipso facto, the obligation to pay interest hereunder shall be
reduced to the Maximum Rate; and if from any circumstance whatsoever, Holder
shall ever receive interest, the amount of which would exceed the amount
collectible at the Maximum Rate, such amount as would be excessive interest
shall be applied to the reduction of the principal balance remaining unpaid
hereunder and not to the payment of interest. This provision shall control every
other provision in any and all other agreements and instruments existing or
hereafter arising between Maker and Holder with respect to the indebtedness
evidenced hereby.

         This Note is intended as a contract under and shall be construed and
enforceable in accordance with the laws of the State of Tennessee, except to the
extent that federal law may be applicable to the determination of the Maximum
Rate.

         As used herein, the terms "Maker" and "Holder" shall be deemed to
include their respective successors, legal representatives and assigns, whether
by voluntary action of the parties or by operation of law.

                             SECURED PROMISSORY NOTE

$1,600,000.00                                                      June 24, 1997

         FOR VALUE RECEIVED, the undersigned, ELECTRONICS ACCESSORY SPECIALISTS
INTERNATIONAL, INC, a Delaware corporation ("Maker"), promises to pay to the
order of SIRROM CAPITAL CORPORATION, a Tennessee corporation ("Payee"; Payee and
any subsequent holder[s] hereof are hereinafter referred to collectively as
"Holder"), at the office of Payee at P. O. Box 30378, Nashville, Tennessee
37241-0378, or at such other place as Holder may designate to Maker in writing
from time to time, the principal sum of ONE MILLION SIX HUNDRED THOUSAND AND
NO/100THS DOLLARS ($1,600,000.00), together with interest on the outstanding
principal balance hereof from the date hereof at the rate of thirteen and
one-half percent (13.5%) per annum (computed on the basis of a 360-day year);
provided, however, that Holder may charge and receive interest upon any renewal
or extension hereof at the greater of (i) the rate set out above, or (ii) any
rate agreed to by the undersigned that is not in excess of the maximum rate of
interest allowed to be charged under applicable law (the "Maximum Rate") at the
time of such renewal or extension.

         Interest only on the outstanding principal balance hereof shall be due
and payable monthly, in arrears, with the first payment being payable on the
first (1st) day of August, 1997, and subsequent payments being payable on the
first (1st) day of each succeeding month thereafter until June 23, 2002 (the
"Maturity Date"), at which time the entire outstanding principal balance,
together with all accrued and unpaid interest; shall be immediately due and
payable in full.

         The indebtedness evidenced hereby may be prepaid in whole or in part,
at any time and from time to time, without penalty. Any such prepayments shall
be credited first to any accrued and unpaid interest and then to the outstanding
principal balance hereof.

         Time is of the essence of this Note. It is hereby expressly agreed that
in the event that any default be made in the payment of principal or interest as
stipulated above, which default is not cured within five (5) days; or in the
event that any default or event of default shall occur under that certain Loan
Agreement of even date herewith, between Maker and Payee (as may be amended from
time to time, the "Loan Agreement"), which default or event of default is not
cured following the giving of any applicable notice and within any applicable
cure period set forth in said Loan Agreement; or should any default by Maker be
made in the performance or observance of any covenants or conditions contained
in any other instrument or document now or hereafter evidencing, securing or
otherwise relating to the indebtedness evidenced hereby (subject to any
applicable notice and cure period provisions that may be set forth therein);
then, and in such event, the entire outstanding principal balance of the
indebtedness evidenced hereby, together with any other sums advanced hereunder,
under the Loan Agreement and/or under any other instrument or document now



<PAGE>   2


or hereafter evidencing, securing or in any way relating to the indebtedness
evidenced hereby, together with all unpaid interest accrued thereon, shall at
the option of Holder and without notice to Maker, at once become due and payable
and may be collected forthwith, regardless of the stipulated date of maturity.
Upon the occurrence of any default as set forth herein, at the option of Holder
and without notice to Maker, all accrued and unpaid interest, if any, shall be
added to the outstanding principal balance hereof, and the entire outstanding
principal balance, as so adjusted, shall bear interest thereafter until paid at
an annual rate (the "Default Rate") equal to the lesser of (i) the rate that is
seven percentage points (7.0%) in excess of the above-specified interest rate,
or (ii) the Maximum Rate in effect from time to time, regardless of whether or
not there has been an acceleration of the payment of principal as set forth
herein. All such interest shall be paid at the time of and as a condition
precedent to the curing of any such default.

         In the event this Note is placed in the hands of an attorney for
collection, or if Holder incurs any reasonable costs incident to the collection
of the indebtedness evidenced hereby, Maker and any indorsers hereof agree to
pay to Holder an amount equal to all such reasonable costs, including without
limitation all reasonable attorney's fees and all court costs.

         Presentment for payment, demand, protest and notice of demand, protest
and nonpayment are hereby waived by Maker and all other parties hereto. No
failure to accelerate the indebtedness evidenced hereby by reason of default
hereunder, acceptance of a past-due installment or other indulgences granted
from time to time, shall be construed as a novation of this Note or as a waiver
of such right of acceleration or of the right of Holder thereafter to insist
upon strict compliance with the terms of this Note or to prevent the exercise of
such right of acceleration or any other right granted hereunder or by applicable
laws. No extension of the time for payment of the indebtedness evidenced hereby
or any installment due hereunder, made by agreement with any person now or
hereafter liable for payment of the indebtedness evidenced hereby, shall operate
to release, discharge, modify, change or affect the original liability of Maker
hereunder or that of any other person now or hereafter liable for payment of the
indebtedness evidenced hereby, either in whole or in part, unless Holder agrees
otherwise in writing. This Note may not be changed orally, but only by an
agreement in writing signed by the party against whom enforcement of any waiver,
change, modification or discharge is sought.

         The indebtedness and other obligations evidenced by this Note are
further evidenced by (i) the Loan Agreement and (ii) certain other instruments
and documents, as may be required to protect and preserve the rights of Maker
and Payee as more specifically described in the Loan Agreement.

         All agreements herein made are expressly limited so that in no event
whatsoever, whether by reason of advancement of proceeds hereof, acceleration of
maturity of the unpaid balance hereof or otherwise, shall the amount paid or
agreed to be paid to Holder for the use of the money advanced or to be advanced
hereunder exceed the Maximum Rate. If from any circumstances whatsoever, the
fulfillment of any provision of this Note or any other agreement or instrument
now or hereafter evidencing, securing or in any way relating to the indebtedness


                                       2
<PAGE>   3


evidenced hereby shall involve the payment of interest in excess of the Maximum
Rate, then, ipso facto, the obligation to pay interest hereunder shall be
reduced to the Maximum Rate; and if from any circumstance whatsoever, Holder
shall ever receive interest, the amount of which would exceed the amount
collectible at the Maximum Rate, such amount as would be excessive interest
shall be applied to the reduction of the principal balance remaining unpaid
hereunder and not to the payment of interest. This provision shall control every
other provision in any and all other agreements and instruments existing or
hereafter arising between Maker and Holder with respect to the indebtedness
evidenced hereby.

         This Note is intended as a contract under and shall be construed and
enforceable in accordance with the laws of the State of Tennessee, except to the
extent that federal law may be applicable to the determination of the Maximum
Rate.

         As used herein, the terms "Maker" and "Holder" shall be deemed to
include their respective successors, legal representatives and assigns, whether
by voluntary action of the parties or by operation of law.

                         INDEPENDENT AUDITORS' CONSENT


The Board of Directors
Mobility Electronics, Inc.

We consent to the use of our reports included herein and to the reference to
our firm under the headings "Selected Consolidated Financial Data" and
"Experts" in the prospectus. Our report dated February 4, 2000, contains an
explanatory paragraph that states that the Company has suffered recurring
losses from operations and has a net capital deficiency, which raise
substantial doubt about its ability to continue as a going concern. The
consolidated financial statements do not include any adjustments that might
result from the outcome of that uncertainty.
