                                   THE COMPANY

         The Company offers build-to-order services, designs and markets
products consisting of semiconductor memory modules, designs and builds memory
module testers and provides design services in conjunction with the licensing of
its Touch sensor products. Operating under the Tanisys Technology name since
1994, the Company has developed into an independent manufacturer of standard and
custom semiconductor memory modules for a variety of computer and electronics
OEMs. The Company also markets the DarkHorse line of memory testers and licenses
its proprietary Tanisys Touch technology. In 1997, the Company changed its focus
from selling off-the-shelf semiconductor memory modules to specializing in
services designed to provide OEM customers with build-to-order board-level
solutions. Currently, approximately 50% of the Company's revenues are derived
from selling off-the-shelf semiconductor memory modules. In connection with its
build-to-order services, the Company has developed extensive design and
manufacturing expertise under its Comprehensive Logistics and Supply Solutions
("CLASS") Program to respond to its customers' rapidly changing requirements. To
this end, the Company maintains design centers and manufacturing facilities in
Austin, Texas and Hamilton, Lanarkshire, Scotland. The Company's principal
customers include electronic OEMs, semiconductor manufacturers, computer
distributors, value-added resellers ("VARs") and system integrators. The
Company's OEM customers currently include Siemans AG, LG Semicon, Dell Computer
Corporation, Bay Networks and Solectron Corp. The Company also provides products
for the build-to-order programs of Compaq Computer Corporation, Dell Computer
Corporation and Hewlett Packard Company.

         The Company was organized under the laws of the Province of British
Columbia, Canada, on January 27, 1984, as Montebello Resources Ltd. to exploit
the mineral, oil and gas exploration business in British Columbia and Manitoba,
Canada. On October 7. 1992, the Company changed its name to First American
Capital Group Inc. The Company was unsuccessful in the oil and gas business, and
in 1992 deemed itself inactive pursuant to the rules and regulations of the
Vancouver Stock Exchange ("VSE"), where its common stock, no par value per share
(the "Common Stock"), had been traded. During the first two quarters of 1993,
the Company was reorganized in accordance with the rules of the VSE. As part of
this reorganization, the Company acquired certain computer game controller
technology, which was the forerunner of the Company's Tanisys Touch technology.
The Company changed its name to Rosetta Technologies Inc. on May 13, 1993. In
June 1993, Rosetta Marketing and Sales, Inc. was incorporated in the State of
Texas as a wholly owned subsidiary of the Company to provide marketing for the
Company's products. On June 30, 1993, the Company acquired all of the
outstanding capital shares of Timespan Communications Corp. ("Timespan") for the
issuance of Common Stock and the assumption of certain indebtedness. Also on
June 30, 1993, the Company filed Articles of Continuance with the Secretary of
State of the State of Wyoming and was issued a Certificate of Continuance, which
continued the corporation's charter under the Wyoming Business Corporation Act
as if it had been incorporated thereunder. On October 1, 1993, the Company
caused all of the software technology owned by Timespan to be transferred to the
Company, and Timespan subsequently has been liquidated. On July 11, 1994, the
Company changed its name to Tanisys Technology, Inc. The Company's Common Stock
has traded on the NASDAQ SmallCap Market under the symbol "TNSU" since May 22,
1997.

         Effective May 21, 1996, the Company acquired, through mergers with its
wholly owned subsidiaries, all of the outstanding common stock of 1st Tech
Corporation ("1st Tech") and DarkHorse Systems, Inc. ("DarkHorse") and began
operations in Austin, Texas as a consolidated group of companies providing
custom design, engineering and manufacturing services, test solutions and
standard and custom module products to leading OEMs in the computer networking
and telecommunications industries.

RECENT DEVELOPMENTS

         Effective February 1998, the Company established Tanisys (Europe)
Limited, a wholly owned subsidiary of the Company located in Scotland. Tanisys
(Europe), Limited will offer its Comprehensive Logistics and Supply Solutions
("CLASS") program, build-to-order services, turn-key manufacturing services and
manufacture and market products consisting of semiconductor memory modules.
Tanisys (Europe), Limited also will serve as the European sales and marketing

         Pursuant to a Convertible Preferred Stock Purchase Agreement dated June
30, 1998 (the "Purchase Agreement") between the Company and KA Investments LDC,
a Cayman Islands corporation ("KA Investments"), the Company issued 400 shares
of its 5% Series A Convertible Preferred Stock, par value $1.00 per share
("Series A Stock"), for an aggregate purchase price of $4,000,000. The Series A
Stock is convertible into shares of Common Stock pursuant to a formula based
upon the Conversion Price, which shall be equal to the lower of either (a) $2.31
per share or (b) 80% of the average of the three lowest closing bid prices per
share of Common Stock for the 30 trading days immediately prior to conversion
(as more fully described in the Articles of Incorporation of the Company).
Dividends accrue on the Series A Stock at a rate of 5% per annum, and may be
paid in shares of Common Stock, but must be paid in cash upon the occurrence of
certain events. The Company is required to redeem certain of the shares of
Series A Stock upon the occurrence of certain triggering events. In addition,
the Company granted warrants (the "Warrants") to KA Investments, Midori Capital
Corporation ("Midori"), Hoth Incorporated ("Hoth") and Randy Stein ("Stein") (KA
Investments, Midori, Hoth and Stein collectively referred to herein as the
"Selling Stockholders") to purchase an aggregate of approximately 200,000 shares
of Common Stock at a purchase price of $3.00 per share (subject to adjustment as
provided by the terms of the Warrants). The Warrants may be exercised on or
before June 30, 2002. Pursuant to a Registration Rights Agreement between the
Company and KA Investments dated June 30, 1998, the Company granted the Selling
Stockholders certain registration rights related to the shares of Common Stock
issuable upon conversion of the Series A Stock and upon the exercise of the
Warrants. The Registration Statement to which this Prospectus is a part has been
filed pursuant to the terms of such Registration Rights Agreement and registers
the resale by the Selling Stockholders of such shares of Common Stock issuable
upon conversion of the Series A Stock and upon exercise of the Warrants. Each of
the Purchase Agreement, the Registration Rights Agreement, a form of the
Warrants and the Articles of Incorporation of the Company, as amended
(containing the terms of the Series A Stock) have been filed as exhibits to the
Registration Statement to which this Prospectus is a part.

         On July 27, 1998, the Company announced its results for its third
fiscal quarter ended June 30, 1998. Gross profit for the quarter decreased to
$600,000 on $6.8 million in net sales, a 9.3% gross margin, from $1.5 million
gross profit on $11.2 million in net sales, a 13.1% gross margin, in the third
quarter of fiscal 1997. For the third quarter of fiscal 1998 the Company
reported a net loss of $2.6 million, as compared to a $2.3 million loss in the
same quarter of 1997. Net loss per share decreased to $0.12 per share in the
third quarter of fiscal 1998 as compared to $0.13 in the third quarter of fiscal
1997.

                                  THE BUSINESS

INDUSTRY BACKGROUND

         The demand for semiconductor memory modules in digital electronic
systems has grown significantly over the last several years, resulting in the
increased importance of memory in determining system performance. An increasing
demand for greater system performance requires that electronics manufacturers
increase the amount of memory incorporated into a system.

         Factors contributing to the growing demand for memory include growing
unit sales of personal computers ("PCs") in the business and consumer market
segments; increasing use of PCs to perform memory-intensive graphics tasks;
increasingly faster microprocessors; the release of increasingly memory
intensive software; and the increasing performance requirements of workstations,
servers and networking and telecommunications equipment.

         Semiconductor memory products are segmented into three primary classes:
Dynamic Random Access Memory ("DRAM"), Static Random Access Memory ("SRAM") and
non-volatile memory, such as Flash memory. DRAM typically is the large "main"
memory of systems; SRAM provides higher performance; and Flash memory and other
non-volatile memory retain their contents when power is removed. In addition,
within each of these broad categories of memory products, semiconductor
manufacturers are offering an increasing variety of memory devices which are
designed for application specific uses.

         The growing variety of memory components also drives demand for memory
tester systems to test each of these memory module types.

                                       -4-

<PAGE>   6

THE DRAM MARKET

         Of the three primary classes of semiconductor memory, DRAM is
predominately used in computers due to lower cost and increased performance.
Market demand for higher performance PCs and workstations and the increased
focus on high-throughput networking and telecommunications systems are creating
a need for higher volumes of DRAM memory in electronic systems. For example,
International Business Machines Corp ("IBM") has estimated that PCs use 70% of
all memory, and market researcher International Data Corporation ("IDC") expects
the average amount of memory used by each PC to grow from 19.6 megabytes in 1996
to 96 megabytes by 2001.

         The Company believes the near-term DRAM market will fragment into
increased numbers of semiconductor memory module designs due to different
architectures, voltages and densities emerging for new systems while demand
continues for current and older designs. Popular among the architectures are
SDRAM, Synchronous Graphics RAM ("SGRAM"), RAMBUS (a new proprietary memory
technology), Video RAM ("VRAM"), Fast Page Mode ("FPM") and Extended Data Out
("EDO"). DRAM integrated circuits are undergoing a shift to 64 megabits
("Mbits") and in operating voltages from 5.0 volts to 3.3 volts and less.
Therefore, the Company anticipates the combinations of module types will greatly
increase over the next several years.

THE SRAM MARKET

         The market for SRAM typically is segmented into low power and high
speed segments. Low power SRAM devices are used primarily in computing or
electronics industry applications in which minimal power consumption is the top
priority. Popular uses of low power SRAM devices include portable computers that
rely on battery power.

         The primary market demand for high speed SRAM devices is to "buffer"
fast system components from slower system components. In PCs, the most common
use of SRAM devices has been as "cache" memory, which increases a system's
performance and avoids having the increasingly faster microprocessor waiting on
slower DRAM. Access rates of DRAMs have not increased as fast as the speed of
microprocessors, and therefore, the demand for cache memory has increased. High
speed SRAMs also are seeing a rapid proliferation of configuration combinations
due to advances in speed, architecture, density and operating voltages. These
advances are needed primarily due to the increasing speed and complexity of
microprocessors such as the Pentium II, Pentium Pro, the PowerPC and the Alpha
microprocessor family. High speed SRAMs are achieving access times below 3
nanoseconds and are developing synchronous modes similar to SDRAMs to meet the
needs of these new microprocessors.

THE FLASH MEMORY MARKET

         Flash memory is a specialized non-volatile memory that can be updated
similar to DRAM but retains its data after power has been turned off. The
ability to update the contents of Flash memory is the main benefit relative to
most other non-volatile memory devices, such as erasable programmable read only
memory ("EPROM") devices, that makes Flash memory useful for containing software
which is likely to need updating. Typical uses include Basic Input Output System
("BIOS") for PCs, control memory for the rapidly evolving market of thin
client/network computer/Windows terminals, control programs for routers and
other networking equipment and storage for portable computers, personal digital
assistants and digital cameras. Consequently, the market for Flash memory is
growing rapidly.

         Flash memory is often packaged in removable modules to meet the needs
of portable applications. These modules vary widely for their target systems.
There are many Flash memory architectures available in the market today, which
are often offered in multiple modes and voltages. Therefore, Flash memory has
many configurations and the number of configurations has proliferated widely.

MEMORY MODULE MARKET

         Semiconductor memory modules are small printed circuit board assemblies
containing semiconductor memory devices and support circuitry. Many computer and
electronic systems use semiconductor memory modules as standard architectural
components. The modules permit OEMs to more easily upgrade their systems and to
increase flexibility by permitting different types of modules to configure the
one base system for multiple price or performance targets. Semiconductor memory
modules often attach directly to a computer system board, eliminating or
reducing the need 



                                      -5-
<PAGE>   7

to include memory devices on the system board for space reasons as well as
flexibility of the base system. Semiconductor memory modules also permit OEMs to
manufacture systems on a build-to-order basis by permitting the OEM to configure
the system after the customer's order is placed. The benefits of build-to-order
for OEMs are faster availability, increased customer satisfaction, reduced
investment in inventories and reduced costs. Semico Research Corporation
estimates that the market size for semiconductor memory modules in 1997 was
$22.6 billion worldwide.

         The memory module market is segmented into off-the-shelf and custom
components. Off-the-shelf modules often comply with industry standards and are
available from multiple vendors. These are usually popular, high volume designs
using DRAM memory which are used in desktop PCs, notebook computers, network
routers, disk drive controllers and printers. These modules typically are sold
directly to OEMs and to end users via computer resellers.

         Custom semiconductor memory modules meet the unique needs of OEM
computer and electronic systems. The proliferation of memory device options has
resulted in specialized semiconductor memory modules that are ideal for the
performance of a particular system or a set of applications but are not
available off the shelf. These custom modules are typically contracted from a
few suppliers. The limited market for such modules often dictates build-to-order
manufacturing in order to limit inventory risks.

         Computer and electronics manufacturers frequently choose to use memory
expert partners for the design and manufacture of semiconductor memory modules
due to the wide array of memory devices which can be considered for a target
system. Increasing speeds make the design and testing of modules more complex,
thus using memory partners permits system manufacturers to focus on
differentiating their product. OEMs outsource these services in a range of
levels, including build-to-print (manufacturing only), turnkey design and
manufacture, vendor specification and build-to-order.

         The manufacturers of semiconductor memory modules consist of two
subsets: semiconductor manufacturers who build modules and independent third
parties who acquire memory devices and integrate them into modules.
Semiconductor vendors controlled 64% of the module market in 1993 while third
party vendors controlled 57% in 1996 according to Semico Research Corporation.
The Company expects the trend toward dominance by independent third parties to
continue as it believes that semiconductor manufacturers may not have a business
model in place which is suited to meet the needs of many large customers of
custom semiconductor memory modules, including support for build-to-order.

         Independent third party manufacturers of semiconductor memory modules
supply product to two primary market segments: the OEM channel and the reseller
channel. Third party suppliers to the OEM channel typically offer custom
product, although some computer and peripheral OEMs use off-the-shelf
semiconductor memory modules. Third party suppliers to the reseller channel
typically offer standard DRAM semiconductor memory modules as an upgrade product
sold through computer distributors and retail channels. Semiconductor
manufacturers sell modules almost exclusively to OEMs. Both semiconductor memory
suppliers and independent third party module manufacturers are customers for
module testers, and as such, represent both potential customers and competitors
of the Company. The memory module tester market is described below under the
heading "Memory Module Tester Market."

MEMORY MODULE TESTER MARKET

         Memory module testers are important to assure that semiconductor memory
modules meet the necessary specifications of performance. Memory module tester
use typically is segmented into system manufacture and system aftermarket.
System manufacture typically involves the manufacturer of the memory module
being able to test its completed modules. This usually requires "at speed"
testing, where the module is exercised under the same demands as actual use.
Buyers generally evaluate reliability, productivity, accuracy, advanced
automation, software flexibility, service, customer support and price. The
Company believes that these purchase criteria are typical of module tester
buyers as well. Most manufacturers of semiconductor memory modules perform "at
speed" testing of all modules with exacting and accurate testers. Significant
expansion of test capacity is likely due to changing architectures and strong
growth of memory demand.

         The actual test for a module is unique to its design in terms of
architecture, pinout, speed rating, voltage, organization and size and will use
any of several common test algorithms. Therefore, the number of potential memory


                                      -6-
<PAGE>   8

test configurations is much greater than the number of semiconductor memory
modules. This makes test development a potentially costly task. The ability of a
tester manufacturer to provide support for the development of low cost, accurate
tests is a significant consideration in the buying decision.

         Module testing requirements for the system aftermarket are typically
less robust. Memory additions to systems in use typically are already tested in
accordance with the needs of the system manufacture segment and need only module
identification to assure the correct module is being installed. Servicing of
failed systems often requires limited testing of modules but typically does not
require "at speed" testing. As a result, aftermarket module testing usually has
higher sensitivity for portability and cost than does module testing at the time
of system manufacture.

TOUCH SENSOR MARKET

         The touch sensor market is extremely broad since the sensor is capable
of being utilized in any application where a switch is needed. Any product which
benefits from a low profile, sealed, environmentally robust, highly durable, low
cost, simple or easily customized switch is a very good candidate for a touch
sensor switch.

TOUCH SENSOR PRODUCTS

         Tanisys Touch is a proprietary technology which the Company attempts to
protect by patents, copyrights and trademarks, and is available for licensing to
third parties for incorporation into their products. The Company licenses
Tanisys Touch to OEMs which embed it into various products as a robust switching
mechanism. The touch sensor market is primarily an alternative to a variety of
switch technologies such as mechanical switches, membrane switches and bubble
switches.

         Some advantages of Tanisys Touch relative to alternative switch
technologies are no moving parts, high reliability, ability to work through most
plastics, easy customization, ability to work on multiple materials and low
cost. Relative to other vendors' touch implementations, Tanisys Touch does not
need reference capacitors, analog to digital converters or multiple electrodes.
Instead, the Company's proprietary technology is designed to be a reliable,
simple, low cost touch implementation, and the Company intends to position these
advantages against alternative switch technologies.

CUSTOMERS, SALES AND MARKETING

         The Company's primary customers include computer and electronics OEMs,
semiconductor manufacturers, distributors, corporate end users, VARs and systems
integrators. In fiscal 1997 and 1996, the Company's ten largest customers
accounted for approximately 53.2% and 45.3% of net sales, respectively. During
fiscal 1997, the Company had one customer, Tandy Corporation, that accounted for
12.0% of net sales. In fiscal 1996, no one customer accounted for more than 10%
of net sales.

         The Company primarily sells its module products directly and through a
network of independent sales representative organizations to OEM customers
worldwide. The Company sells the majority of its tester products directly to
other module manufacturers and sells a portion through distribution partners and
independent sales representative organizations. Licensing of Tanisys Touch is
through licensing agreements with customers.

         The Company maintains relationships with leading global suppliers of
memory semiconductor devices and frequently works jointly with these suppliers
in quoting customer opportunities.

         The Company's OEM marketing activities include advertising in trade and
business magazines, direct mail and solicitation via the Company's Internet web
site.

         Sales generally are made against standard customer purchase orders. The
Company's backlog generally includes those customer orders for which it accepted
purchase orders and planned shipment dates within the next year. Backlog is not
an indicator of future sales, and orders in the backlog are subject to change in
delivery terms or even cancellation. Accordingly, there is no assurance that
current backlog will lead to future sales. The Company's total backlog was $2.4
million and $356,000 at fiscal 1997 and 1996 year end, respectively.

RESEARCH AND DEVELOPMENT

         The Company's management believes that the timely development of new
products and technologies is essential to maintain the Company's competitive
position. In the electronics market, the Company's research and development
activities are focused primarily on new module products, the continual
improvement in memory test products and solutions and the ongoing improvement in
manufacturing processes and technologies. Additionally, the Company provides
research and development services for customers either as joint or contracted
development. The


                                      -9-
<PAGE>   11

Company plans to continue to devote substantial research and development efforts
to the design of new module products which address the requirements of OEM,
corporate and retail customers.

         The Company's management believes that its Tanisys Touch technology has
been developed to a viable commercial level and that the next step is
introduction of consumer products utilizing Tanisys Touch into the marketplace
by OEMs. Support continues to be provided to OEMs in the PC and appliance
industries toward this end.

         The Company's research and development expenses were $2.6 million in
fiscal 1997, $1.1 million in fiscal 1996 and $410,000 in fiscal 1995.

COMPETITION

         The memory module and memory test equipment industries are intensely
competitive. Each of these markets includes a large number of competitive
companies, several of which have achieved a substantial market share. Certain of
the Company's competitors in each of these markets have substantially greater
financial, marketing, technical, distribution and other resources, greater name
recognition, lower cost structures and larger customer bases than the Company.
In the memory module market, the Company competes against semiconductor
manufacturers that maintain captive memory module production capabilities,
including Samsung Electronics Company Limited ("Samsung") and Micron
Electronics, Inc. (a subsidiary of Micron Technology, Inc.). The Company also
competes with independent memory module manufacturers, including Smart Modular
Technologies, Inc. and Kingston Technology, Inc. In the memory tester market,
the Company competes primarily with companies such as Hewlett-Packard, Inc. and
Advantest, Inc. Competition for the Company's CLASS business of manufacturing
services includes SCI Systems, Inc. and Avex Electronics, Inc. The Company faces
competition from current and prospective customers that evaluate the Company's
capabilities against the merits of manufacturing products internally. In some
cases the Company's tester customers represent direct competition to the
Company's memory module business. In addition, certain of the Company's
competitors, such as Samsung, are significant suppliers to the Company. These
suppliers may have the ability to manufacture competitive products at lower
costs than the Company as a result of their higher levels of integration. The
Company also faces competition from new and emerging companies that have
recently entered or may in the future enter the markets in which the Company
participates.

         The Company expects its competitors to continue to improve the
performance of their current products, to reduce their current product sales
prices and to introduce new products that may offer greater performance and
improved pricing, any of which could cause a decline in sales or loss of market
acceptance of the Company's products. There can be no assurance that
enhancements to or future generations of competitive products will not be
developed that offer better prices or technical performance features than the
Company's products. To remain competitive, the Company must continue to provide
technologically advanced products and manufacturing services, improve quality
levels, offer flexible delivery schedules, deliver finished products on a
reliable basis, reduce manufacturing and testing costs and compete favorably on
the basis of price. In addition, increased competitive pressure has led in the
past, and may continue to lead to, intensified price competition, resulting in
lower prices and gross margin, which could materially adversely affect the
Company's business, financial condition and results of operations. There can be
no assurance that the Company will be able to compete successfully in the
future.

protect its intellectual property rights through trade secrets, copyrights,
trademarks and a variety of other measures, including non-disclosure agreements.
There can be no assurance, however, that such measures will provide adequate
protection for the Company's trade secrets or other proprietary information,
that disputes with respect to the ownership of its intellectual property rights
will not arise, that the Company's trade secrets or proprietary technology will
not otherwise become known or be independently developed by competitors or that
its intellectual property rights can otherwise be protected meaningfully. There
can be no assurance that patents will issue from pending or future applications
or that if patents are issued, they will not be challenged, invalidated or
circumvented, or that rights granted thereunder will provide meaningful
protection or other commercial advantage. Furthermore, there can be no assurance
that third parties will not develop similar products, duplicate the Company's
products or design around the patents owned by the Company or that third parties
will not assert intellectual property infringement claims against the Company.
In addition, there can be no assurance that foreign intellectual property laws
will adequately protect the

INVOLVES A HIGH DEGREE OF RISK. EACH INVESTOR SHOULD CAREFULLY EXAMINE THIS
ENTIRE PROSPECTUS AND SHOULD GIVE PARTICULAR ATTENTION TO THE RISK FACTORS SET
FORTH BELOW.

HISTORY OF LOSSES; PROFITABILITY UNCERTAIN.

         The Company has experienced operating losses since inception. At March
31, 1998, the Company had an accumulated deficit of approximately $25 million.
Primarily as a result of its acquisitions in 1996 and 1997, the Company
generated revenues of approximately $48 million during the fiscal year ended
September 30, 1997.

         In the future, the Company expects to have increased cash outflow
requirements as a result of expenditures related to the expansion of sales and
marketing activity, expansion of manufacturing capacity, and possible investment
in or acquisition of additional complementary products, technologies or
businesses. The cash needs of the Company have changed significantly as a result
of the acquisitions completed during the last two years and the support
requirements of the added business focus areas. There can be no assurance that
the Company will not continue to incur losses, that the Company will be able to
raise cash as necessary to fund operations or that the Company will ever achieve
profitability.

FUTURE ADDITIONAL CAPITAL REQUIREMENTS; NO ASSURANCE FUTURE CAPITAL WILL BE
AVAILABLE.

         The Company's capital requirements will depend on numerous factors,
including market acceptance and demand for its products; the resources the
Company devotes to the development, manufacture and marketing of its products;
the progress of the Company's product development programs; the resources
required to protect the Company's intellectual property; the resources expended,
if any, to acquire complementary businesses, products and technologies; and
other factors. The timing and amount of such capital requirements cannot be
accurately predicted. Funds also may be used for the acquisition of businesses,
products and technologies that are complementary to those marketed by the
Company. Consequently, although the Company believes that its revenues and other
sources of liquidity will provide adequate funding for its capital requirements
through at least 1998, the Company may be required to raise additional funds
through public or private financings, collaborative relationships or other
arrangements. There can be no assurance that the Company will not require
additional funding or that such additional funding, if needed, will be available
on terms attractive to the Company or at all. Holders of the Series A Stock have
certain rights of first refusal until approximately June 30, 1999 with respect
to certain future equity financings of the Company. Any additional equity
financings may be dilutive to stockholders, and debt financing, if available,
may involve restrictive covenants. In addition, the number of shares of Common
Stock issuable upon the conversion of the Series A Stock is subject to
adjustment upon the occurrence of certain events. Such adjustments may be
dilutive to stockholders and may inhibit the Company's ability to consummate
additional equity financings.

EFFECTS OF DELISTING FROM NASDAQ SMALLCAP MARKET; LACK OF LIQUIDITY OF LOW
PRICED STOCKS.

         If the Company fails to maintain the qualification for its Common Stock
to trade on the NASDAQ SmallCap Market, its securities could be subject to
delisting. The NASDAQ Stock Market recently announced increases in the
quantitative standards for maintenance of listings on The NASDAQ SmallCap
Market. The revised standards for continued listing, which became effective in
February 1998, include maintenance of any of (x) $2,000,000 of net


                                      -13-
<PAGE>   15

tangible assets, (y) $35,000,000 of market capitalization or (z) $500,000 of net
income for two of the last three years and a minimum bid price per share of
$1.00. Although the Company is currently in compliance with the new NASDAQ
SmallCap Market continued listing requirements, no assurances can be given that
the Company will be able to maintain such compliance in the future. In the event
the Company is unable to satisfy the continued listing requirements, trading, if
any, in the Common Stock would thereafter be conducted in the over-the-counter
markets in the so-called "pink sheets" or the National Association of Securities
Dealers' "Electronic Bulletin Board." Consequently, the liquidity of the
Company's Common Stock likely would be impaired, not only in the number of
shares which could be bought and sold, but also through delays in the timing of
the transactions, reduction in security analysts' and the news media's coverage,
if any, of the Company and lower prices for the Company's securities than might
otherwise prevail.

         In addition, if the Common Stock were to become delisted from trading
on the NASDAQ SmallCap Market and the trading price of the Common Stock were
below $5.00 per share, trading in the Common Stock also would be subject to the
requirements of certain rules promulgated under the Exchange Act, which require
additional disclosures by broker-dealers in connection with any trades involving
a stock defined as a penny stock (generally, any non-NASDAQ equity security that
has a market price of less than $5.00 per share, subject to certain exceptions).
Such rules require the delivery, prior to any penny stock transaction, of a
disclosure schedule explaining the penny stock market and the risks associated
therewith, and impose various sales practice requirements on broker-dealers who
sell penny stock to persons other than established customers and accredited
investors (which are generally institutions). For these types of transactions,
the broker-dealer must make a special suitability determination for the purchase
and have received the purchaser's written consent to the transaction prior to
the sale. The additional burdens imposed upon broker-dealers by such
requirements may discourage broker-dealers from effecting transactions in Common
Stock, which could severely limit the market liquidity of Common Stock and the
ability of purchasers in this offering to sell their shares of Common Stock in
the secondary market.

POTENTIAL ADVERSE EFFECTS OF CONVERSION OF SERIES A STOCK; RISK OF SHORT SELLING

         The Company cannot predict what effect, if any, the conversion of
Series A Stock into Common Stock and/or the exercise of the Warrants for Common
Stock and sale of such Common Stock into the public market, will have on the
market price for the Company's Common Stock. Offers or sales of significant
quantities of the Company's Common Stock, or the perception that such sales may
occur or have occurred, could adversely affect the market price. The conversion
feature of the Series A Stock operates such that the Selling Stockholder
receives more shares of the Common Stock upon conversion when the market price
of the Common Stock is lower. In the event the Selling Stockholders sell a large
number of shares of Common Stock into the public market over a short time, the
market price for the Common Stock could decline. Such a decline may make future
equity financings more difficult for the Company to obtain on an acceptable
basis, if at all.

         The terms of the Purchase Agreement do not prohibit the holders of
Series A Stock from engaging in short sales. Sales of Common Stock by the
Selling Stockholders or others, whether short or long selling, could drive the
market price down, after which the holders of Series A Stock could convert
shares of Series A Stock into Common Stock at a lower price, then sell such
shares of Common Stock when the market price rises to a higher level. There is a
limit on the number of shares of Series A Stock which may be converted in a
given period subject to certain exceptions. See "Selling Stockholders."


LIMITED OPERATING HISTORY

         Although the Company has been in existence since 1984, its current
operations have been in place only since its acquisition of 1st Tech and
DarkHorse in 1996. Accordingly, the Company is still in many respects subject to
certain risks and uncertainties inherent in a new enterprise, including limited
capital and other resources, reliance on key personnel, operating in a highly
competitive environment, inability to develop long-term relationships with its
customers, suppliers and lenders, lack of name recognition, higher overhead
costs, and difficulty in addressing unanticipated problems, delays and expenses.


                                      -14-

<PAGE>   16

SIGNIFICANT CUSTOMER CONCENTRATION

         A significant percentage of the Company's net sales are produced by a
relatively small number of customers. In fiscal 1997 and 1996, the ten largest
customers accounted for approximately 53.2% and 45.3% of net sales,
respectively. One customer, Tandy Corporation, accounted for 12.0% of total
sales in fiscal 1997, while no one customer accounted for more than 10% of total
sales in fiscal 1996. While the Company expects to continue to be dependent on a
relatively small number of customers for a significant percentage of its net
sales, there can be no assurance that any of the top ten customers in fiscal
1997 will continue to utilize the Company's products or services. Absent
replacement or other sales growth, the loss of any significant customer could
materially and adversely affect the Company's result of operations, business and
financial condition. The actual customers producing the sales are different
between the two periods, and the Company expects this type of variation in
volume of purchases from a particular customer to continue.

         The Company in general has no firm long-term volume commitments from
its customers and generally enters into individual purchase orders and
agreements with non-binding forecasts. Customer purchase orders and forecasts
are subject to change, cancellation or delay with little or no consequence to
the customer. Therefore, the Company has experienced such changes and
cancellations and expects to continue to do so in the future. The replacement of
canceled, delayed or reduced purchase orders with new business cannot be
assured. The Company's business, financial condition and results of operations
will depend significantly on its ability to obtain purchase orders from existing
and new customers, upon the financial condition and success of its customers,
the success of customers' products and the general economy. Factors affecting
the industries of the Company's major customers could have a material adverse
effect on the Company's business, financial condition and results of operations.

PRODUCT CONCENTRATION; DEPENDENCE ON MEMORY MARKET

         A substantial majority of the Company's net sales is derived from
memory products. The market for memory products is characterized by frequent
transitions in which products rapidly incorporate new features and performance
standards. A failure to develop products with required feature sets or
performance standards or a delay as short as a few months in bringing a new
product to market could significantly reduce the Company's net sales for a
substantial period, which would have a material adverse effect on the Company's
business, financial condition and results of operations.

         The market for semiconductor memory devices has been cyclical. The
industry has experienced significant economic downturns at various times,
characterized by diminished product demand, accelerated erosion of average
selling prices and production over capacity. During fiscal 1997, there were
significant declines in DRAM and SRAM semiconductor prices. Since the fiscal
1997 year end, there have been continued declines in certain DRAM and SDRAM
semiconductor prices. Because approximately 50% of the Company's net sales are
attributable to the resale of semiconductor memory devices, future price
declines could have a material adverse effect on the Company's business,
financial condition and results of operations.

INTENSE COMPETITION; LIMITED BARRIERS TO ENTRY

         The memory module and memory test equipment industries are intensely
competitive. Each of these markets includes a large number of competitive
companies, several of which have achieved a substantial market share. Certain of
the Company's competitors in each of these markets have substantially greater
financial, marketing, technical, distribution and other resources, greater name
recognition, lower cost structures and larger customer bases than the Company.
In the memory module market, the Company competes against semiconductor
manufacturers that maintain captive memory module production capabilities,
including Samsung and Micron Electronics, Inc. (a subsidiary of Micron
Technology, Inc.). The Company also competes with independent memory module
manufacturers, including Smart Modular Technologies, Inc. and Kingston
Technology, Inc. In the memory tester market, the Company competes primarily
with companies such as Hewlett-Packard, Inc. and Advantest, Inc. Competition for
the Company's CLASS business of manufacturing services includes SCI Systems,
Inc. and Avex Electronics, Inc. The Company faces competition from current and
prospective customers that evaluate the Company's capabilities against the
merits of manufacturing products internally. In some cases the Company's tester
customers represent direct competition to the Company's memory module business.
In addition, certain of the Company's competitors, such as Samsung, are


                                      -15-
<PAGE>   17
significant suppliers to the Company. These suppliers may have the ability to
manufacture competitive products at lower costs than the Company as a result of
their higher levels of integration. The Company also faces competition from new
and emerging companies that have recently entered or may in the future enter the
markets in which the Company participates.

         The Company expects its competitors to continue to improve the
performance of their current products, to reduce their current product sales
prices and to introduce new products that may offer greater performance and
improved pricing, any of which could cause a decline in sales or loss of market
acceptance of the Company's products. There can be no assurance that
enhancements to or future generations of competitive products will not be
developed that offer better prices or technical performance features than the
Company's products. To remain competitive, the Company must continue to provide
technologically advanced products and manufacturing services, improve quality
levels, offer flexible delivery schedules, deliver finished products on a
reliable basis, reduce manufacturing and testing costs and compete favorably on
the basis of price. In addition, increased competitive pressure has led in the
past and may continue to lead to intensified price competition, resulting in
lower prices and gross margin, which could materially adversely affect the
Company's business, financial condition and results of operations. There can be
no assurance that the Company will be able to compete successfully in the
future.

         In addition, barriers to entry in certain of the markets in which the
Company operates are limited, and there can be no assurance that existing or new
competitors will not develop products or provide services that are superior to
the Company's products or services or achieve greater market acceptance.

FLUCTUATIONS IN OPERATING RESULTS

         The Company's results of operations and gross margin have fluctuated
significantly from period to period in the past and may in the future continue
to fluctuate significantly from period to period. Aside from fluctuations
typically resulting from the different products and customer mix associated with
acquisitions, the primary factors that have affected and may in the future
affect the Company's results of operations include the loss of a principal
customer or customers or the reduction in orders from a customer due to excess
product inventory accumulation by such customers, adverse changes in the mix of
products sold by the Company and the inability to procure required components.
Other factors that may affect the Company's results of operations in the future
include fluctuating market demand for and declines in the selling prices of the
Company's products, market acceptance of new products and enhanced versions of
the Company's products, delays in the introduction of new products and
enhancements to existing products, and manufacturing inefficiencies associated
with the startup of new product introductions. In addition, the Company's
operating results may be affected by the timing of new product announcements and
releases by the Company or its competitors, the timing of significant orders,
the ability to produce products in volume, delays, cancellations or
reschedulings of orders due to customer financial difficulties or other events,
inventory obsolescence, including the reduction in value of the Company's
inventories due to unexpected price declines, unexpected product returns, the
timing of expenditures in anticipation of increased sales, cyclicality in the
Company's targeted markets, and expenses associated with acquisitions. In
particular, declines in DRAM, SDRAM and SRAM semiconductor prices could affect
the valuation of the Company's inventory which could result in adverse changes
in the Company's business, financial condition and results of operations.

         The Company's net sales and gross margin have varied and will continue
to vary significantly based on a variety of factors, including the mix of
products sold and the manufacturing services provided, the channels through
which the Company's products are sold, changes in product selling prices and
component costs, the level of manufacturing efficiencies achieved and pricing by
competitors. The selling prices of the Company's existing products have declined
in the past, and the Company expects that prices will continue to decline in the
future. In particular, during fiscal 1997 and 1996, the selling prices of the
Company's existing products declined due to significant declines in DRAM, SDRAM
and SRAM semiconductor prices. Moreover, since the fiscal 1997 year end,
declines in the prices of certain of the Company's existing products have
continued due to further declines in certain DRAM and SDRAM semiconductor
prices. Because a substantial portion of the Company's turnkey sales are
attributable to the resale of semiconductor devices, continued decline in the
prices of these components could have a material adverse effect on the Company's
net sales. Accordingly, the Company's ability to maintain or increase net sales
will be highly dependent upon its ability to increase unit sales volumes of
existing products and to introduce and sell new products in quantities
sufficient to compensate for the anticipated declines in selling prices.
Declining product selling prices may also 


                                      -16-
<PAGE>   18

materially and adversely affect the Company's gross margin unless the Company is
able to reduce its cost per unit to offset declines in product selling prices.
There can be no assurance that the Company will be able to increase unit sales
volumes, introduce and sell new products or reduce its cost per unit. In
addition, the Company's business has in the past been subject to seasonality.
The Company expects that its business will experience more significant
seasonality as it expands its sales and marketing efforts in Europe.

         Sales of the Company's individual products and product lines toward the
end of a product's life cycle typically are characterized by steep declines in
sales, pricing and gross margin, the precise timing of which may be difficult to
predict. The Company could experience unexpected reductions in sales of products
as customers anticipate new product purchases. In addition, to the extent that
the Company manufactures products in anticipation of future demand that does not
materialize, or in the event a customer cancels outstanding orders during a
period of either declining product selling prices or decreasing demand, the
Company could experience an unanticipated decrease in sales of products. These
factors could give rise to charges for obsolete or excess inventory, returns of
products by distributors, or substantial price protection charges or discounts.
In the past, the Company has had to write-down and write-off excess or obsolete
inventory. To the extent that the Company is unsuccessful in managing product
transitions, its business, financial condition and results of operations could
be materially and adversely affected.

         The need for continued significant expenditures for capital equipment
purchases, research and development and ongoing customer service and support,
among other factors, will make it difficult for the Company to reduce its
operating expenses in any particular period if the Company's expectations for
net sales for that period are not met. The Company has significantly increased
its expense levels to support its growth, and there can be no assurance that the
Company will maintain its current level of net sales or rate of growth for any
period in the future. The Company believes that period-to-period comparisons of
the Company's financial results are not necessarily meaningful and should not be
relied upon as indications of future performance. Due to the foregoing factors,
it is likely that in some future period the Company's operating results will be
below the expectations of public market analysts or investors. In such event,
the market price of the Company's securities would be materially and adversely
affected.

DEPENDENCE ON SEMICONDUCTOR, COMPUTER, TELECOMMUNICATIONS AND NETWORKING
INDUSTRIES

         The Company may experience substantial period-to-period fluctuations in
future operating results due to factors affecting the semiconductor, computer,
telecommunications and networking industries. From time to time, each of these
industries has experienced downturns, often in connection with, or in
anticipation of, declines in general economic conditions. A decline or
significant shortfall in growth in any one of these industries could have a
material adverse impact on the demand for the Company's products and therefore a
material adverse effect on the Company's business, financial condition and
results of operations. Moreover, changes in end-user demand for the products
sold by any individual OEM customer can have a rapid and exaggerated effect on
demand for the Company's products from that customer in any given period,
particularly in the event that the OEM customer has accumulated excess
inventories of products purchased from the Company. There can be no assurance
that the Company's net sales and results of operations will not be materially
and adversely affected in the future due to changes in demand from individual
customers or cyclical changes in the semiconductor, computer,
telecommunications, networking or other industries utilizing the Company's
products.

UNCERTAINTY REGARDING PROTECTION OF PROPRIETARY RIGHTS

         In the semiconductor, computer, telecommunications and networking
industries, it is typical for companies to receive notices from time to time
alleging infringement of patents, copyrights or other intellectual property
rights of others. While there is currently no pending intellectual property
litigation involving the Company, the Company may from time to time be notified
of claims that it may be infringing patents, copyrights or other intellectual
property rights owned by third parties. There can be no assurance that third
parties will not in the future pursue claims against the Company with respect to
the alleged infringement of patents, copyrights or other intellectual property
rights. In addition, litigation may be necessary to protect the Company's
intellectual property rights and trade secrets, to determine the validity and
scope of the proprietary rights of others or to defend against third party
claims of invalidity. Any litigation could result in substantial costs and
diversion of resources and could have a material adverse effect on the Company's
business, financial condition and results of operations.


                                      -17-
<PAGE>   19

         There can be no assurance that infringement, invalidity, right to use
or ownership claims by third parties or claims for indemnification resulting
from infringement claims will not be asserted in the future. The failure to
obtain a license under a patent or intellectual property right from a third
party for technology used by the Company could cause the Company to incur
substantial liabilities and to suspend the manufacture of the products utilizing
the intellectual property. In addition, should the Company decide to litigate
such claims, such litigation could be extremely expensive and time consuming and
could materially and adversely affect the Company's business, financial
condition and results of operations, regardless of the outcome of the
litigation.

         The Company attempts to protect its intellectual property rights
through a variety of measures, including non-disclosure agreements, trademarks,
trade secrets and to a lesser extent, patents and copyrights. There can be no
assurance, however, that such measures will provide adequate protection for the
Company's trade secrets or other proprietary information, that disputes with
respect to the ownership of its intellectual property rights will not arise,
that the Company's trade secrets or proprietary technology will not otherwise
become known or be independently developed by competitors or that the Company
can otherwise meaningfully protect its intellectual property rights.

RISKS ASSOCIATED WITH ACQUISITIONS

         As part of its business strategy, the Company expects to make
acquisitions of, or significant investments in, businesses that offer
complementary products and technologies. Any such future acquisitions or
investments would expose the Company to the risks commonly encountered in
acquisitions of businesses. Such risks include, among others, difficulty of
assimilating the operations, information systems and personnel of the acquired
businesses, the potential disruption of the Company's ongoing business, the
inability of management to maximize the financial and strategic position of the
Company through the successful incorporation of acquired employees and
customers, the maintenance of uniform standards, controls, procedures and
policies and the impairment of relationships with employees and customers as a
result of any integration of new management personnel. There can be no assurance
that any potential acquisition will be consummated or, if consummated, that it
will not have a material adverse effect on the Company's business, financial
condition and results of operations.

VOLATILITY OF STOCK PRICES

         There has been a history of significant volatility in the market prices
of the common stock of technology companies, including the Common Stock of the
Company, and it is likely that the market price of the Company's Common Stock
will continue to be subject to significant fluctuations. Factors such as the
timing and market acceptance of new product introductions by the Company, demand
for products of the Company's customers, the introduction of new products by the
Company's competitors, variations in quarterly operating results, changes in
securities analysts' recommendations regarding the Company's Common Stock,
developments in the technology industry and general economic conditions may have
a significant impact on the market price of the Company's Common Stock. In
addition, the equity markets in recent years have experienced significant price
and volume fluctuations that have affected the market prices of technology
companies and that have often been unrelated to the operating performance of
such companies.

SHARES ELIGIBLE FOR FUTURE SALE.

         Sales of shares of Common Stock by existing stockholders under Rule 144
of the Securities Act, or through the exercise of warrants and/or outstanding
vested options, could have an adverse effect on the price of the Common Stock.
As of June 30, 1998, there were approximately 16,000,000 shares of Common Stock
freely tradeable in the public market, and, in addition to the 5,353,374 shares
of Common Stock offered hereby, there were (i) approximately 5,000,000 shares of
Common Stock eligible for sale in the public market upon compliance with the
volume and other limitations contained in Rule 144 of the Securities Act; (ii)
outstanding options to acquire up to approximately 4,032,500 shares of Common
Stock under the Company's stock option plans; (iii) outstanding options to
acquire up to approximately 139,000 additional shares of Common Stock under
option agreements entered into outside of such plans; and (iv) outstanding
warrants to acquire up to approximately 89,000 shares of Common Stock.



                                      -18-
<PAGE>   20

AUTHORIZATION OF PREFERRED STOCK.

         The Company's Articles of Incorporation authorize the issuance of
preferred stock with designations, rights and preferences determined from time
to time by its Board of Directors. Accordingly, the Board of Directors is
empowered, without stockholder approval, to issue preferred stock with dividend,
liquidation, conversion, voting or other rights that could adversely affect the
voting power or other rights of the holders of the Common Stock. In the event of
issuance, the preferred stock could be used, under certain circumstances, as a
method of discouraging, delaying or preventing a change in control of the
Company. Although the Company has no present intention to issue any additional
shares of its preferred stock, there can be no assurance that it will not do so
in the future.

MANAGEMENT OF GROWTH; EXPANSION OF OPERATIONS

         The Company has significantly expanded its operations over the last
several years. This growth has resulted in a significant increase in
responsibility for existing management which has placed, and may continue to
place, a significant strain on the Company's limited personnel and management,
manufacturing and other resources. The Company's ability to manage the recent
and any possible future growth will require a significant expansion of its
manufacturing capacity, accounting and other internal management systems and the
implementation of a variety of procedures and controls. There can be no
assurance that significant problems in these areas will not occur. Any failure
to expand these systems and implement such procedures and controls in an
efficient manner and at a pace consistent with the Company's business could have
a material adverse effect on the Company's business, financial condition and
results of operations.

         In connection with the Company's acquisitions and growth, the Company's
operating expenses have increased significantly, and the Company anticipates
that operating expenses will continue to increase in absolute dollars in the
future. In particular, in order to continue to provide quality products and
customer service and to meet anticipated demands of its customers, the Company
will be required to continue to increase staffing and other expenses, including
expenditures on capital equipment, sales and marketing. Should the Company
increase its expenditures in anticipation of a future level of sales that does
not materialize, the Company's business, financial condition and results of
operations would be materially and adversely affected. Certain customers have
required and may continue to require rapid increases in production and
accelerated delivery schedules which have placed and may continue to place a
significant burden on the Company's resources. In order to achieve anticipated
sales levels and profitability, the Company will continue to be required to
manage its assets and operations efficiently. In addition, should the Company
continue to expand geographically, it may experience certain inefficiencies from
the management of geographically dispersed facilities.

         The Company anticipates that future demand for its products will
require expansion of its current operations and the addition of new production
lines in the future. It also anticipates that it will be required to move to a
larger facility. Should the Company's relocation to this facility be delayed or
should the Company experience any unexpected disruptions associated with this
transition, the Company's results of operations could be materially and
adversely affected. There can be no assurance that any such expansion will be
completed successfully.

RAPID TECHNOLOGICAL CHANGE

         The semiconductor, computer, telecommunications and networking
industries are subject to rapid technological change, short product life cycles,
frequent new product introductions and enhancements, changes in end-user
requirements and evolving industry standards. The Company's ability to be
competitive in these markets will depend in significant part upon its ability to
invest significant amounts of resources for research and development efforts, to
successfully develop, introduce and sell new products and enhancements on a
timely and cost-effective basis and to respond to changing customer requirements
that meet evolving industry standards. For example, the semiconductor memory
market is currently transitioning from fast page mode and EDO memory to SDRAM.
The success of the Company in developing new and enhanced products will depend
upon a variety of factors, including integration of the various elements of its
complex technology, timely and efficient completion of product design, timely
and efficient implementation of manufacturing and assembly processes,
availability of production capacity, achievement of acceptable manufacturing
yields and product performance, quality and reliability. The Company has
experienced, and may in the future experience, delays from time to time in the
development and introduction of new 


                                      -19-
<PAGE>   21

products. Moreover, there can be no assurance that the Company will be
successful in selecting, developing, manufacturing and marketing new products or
enhancements. There can be no assurance that defects or errors will not be found
in the Company's products after commencement of commercial shipments, which
could result in delayed market acceptance of such products. The inability of the
Company to introduce new products or enhancements that contribute to sales could
have a material adverse effect on the Company's business, financial condition
and results of operations.

DEPENDENCE ON SOLE OR LIMITED SOURCES OF SUPPLY

         The Company is dependent on certain suppliers, including limited and
sole source suppliers, to provide key components used in the Company's products.
In particular, the Company is dependent in significant part upon certain limited
or sole source suppliers for critical components in the Company's memory module
and tester products. The electronics industry has experienced in the past, and
may experience in the future, shortages in semiconductor devices, including
DRAM, SDRAM and SRAM memory. The Company has experienced and may continue to
experience delays in component deliveries and quality problems with respect to
certain component deliveries which have caused and could in the future cause
delays in product shipments and have required and could in the future require
the redesign of certain products. The Company generally has no written
agreements with its suppliers. There can be no assurance that the Company will
receive adequate component supplies on a timely basis in the future. The
inability to continue to obtain sufficient supplies of components as required,
or to develop alternative sources if required, could cause delays, disruptions
or reductions in product shipments or require product redesigns which could
damage relationships with current or prospective customers, could increase costs
and/or prices and could have a material adverse effect on the Company's
business, financial condition and results of operations.

DEPENDENCE ON KEY PERSONNEL

         The Company's future operating results depend in significant part upon
the continued contributions of its key technical and senior management
personnel, many of whom would be difficult to replace. The Company's future
operating results also depend in significant part upon its ability to attract,
train and retain qualified management, manufacturing and quality assurance,
engineering, marketing, sales and support personnel. The Company is actively
recruiting such personnel. However, competition for such personnel is intense,
and there can be no assurance that the Company will be successful in attracting,
training or retaining such personnel now or in the future. There may be only a
limited number of persons with the requisite skills to serve in these positions,
and it may be increasingly difficult for the Company to hire such persons over
time. The loss of any key employee, the failure of any key employee to perform
in his or her current position, the Company's inability to attract, train and
retain skilled employees as needed or the inability of the officers and key
employees of the Company to expand, train and manage the Company's employee base
could materially and adversely affect the Company's business, financial
condition and results of operations.

DEPENDENCE ON AVAILABILITY, RECRUITMENT AND RETENTION OF TECHNICAL PERSONNEL

         The Company depends upon its ability to attract, hire and retain
technical personnel who possess the skills and experience necessary to meet the
Company's own personnel needs and the technical requirements of its clients.
Competition for individuals with proven technical skills is intense. The
computer industry in general experiences a high rate of attrition of such
personnel. The Company competes for such individuals with competitors, providers
of outsourcing services, temporary personnel agencies, computer systems
consultants, customers and potential customers. Many large competitors have
announced extensive campaigns to hire additional technical personnel.
Competition for quality technical personnel has continued to intensify,
resulting in increased personnel costs for many computer component
manufacturers. Failure to attract and retain sufficient technical personnel
would have a material adverse effect on the Company's business, operating
results and financial condition.

INTERNATIONAL SALES

         International sales accounted for 3.5% and 2.7% of net sales in fiscal
1997 and 1996, respectively. The Company anticipates that international sales
will increase in future periods and will account for an increasing portion of
net sales. In February 1998, the Company's wholly owned subsidiary, Tanisys
(Europe) Limited, commenced operations in Scotland. As a result, an increasing
portion of the Company's sales will be subject to certain risks, 



                                      -20-
<PAGE>   22

including changes in regulatory requirements, tariffs and other barriers, timing
and availability of export licenses, political and economic instability,
difficulties in accounts receivable collections, natural disasters, difficulties
in staffing and managing foreign subsidiary and branch operations, difficulties
in managing distributors, difficulties in obtaining governmental approvals for
telecommunications and other products, foreign currency exchange fluctuations,
the burden of complying with a wide variety of complex foreign laws and treaties
and potentially adverse tax consequences. The Company is also subject to the
risks associated with the imposition of legislation and regulations relating to
the import or export of high technology products. The Company cannot predict
whether quotas, duties, taxes or other charges or restrictions upon the
importation or exportation of the Company's products will be implemented by the
U.S. or other countries. Because sales of the Company's products have been
denominated to date primarily in U.S. dollars, increases in the value of the
U.S. dollar could increase the price of the Company's products so that they
become relatively more expensive to customers in the local currency of a
particular country, leading to a reduction in sales and profitability in that
country. Future international activity may result in increased foreign currency
denominated sales. Gains and losses on the conversion to U.S. dollars of
accounts receivable, accounts payable and other monetary assets and liabilities
arising from international operations may contribute to fluctuations in the
Company's results of operations. Some of the Company's customer purchase orders
and agreements are governed by foreign laws, which may differ significantly from
U.S. laws. Therefore, the Company may be limited in its ability to enforce its
rights under such agreements and to collect damages, if awarded. There can be no
assurance that any of these factors will not have a material adverse effect on
the Company's business, financial condition and results of operations.

NO ASSURANCE OF PRODUCT QUALITY, PERFORMANCE AND RELIABILITY

         The Company expects that its customers will continue to establish
demanding specifications for quality, performance, reliability and delivery. In
the past, the Company has experienced quality problems resulting in product
returns and cancellations. To date, the Company's quality problems have not had
a significant effect on the Company's results of operations and the known
quality problems have been or are in the process of being remedied. There can be
no assurance that the problems will not occur in the future with respect to
quality, performance, reliability and delivery of the Company's products. If
such problems occur, the Company could experience increased costs, delays in or
cancellations or reschedulings of orders or shipments, delays in collecting
accounts receivable and increases in product returns and discounts, any of which
could have a material adverse effect on the Company's business, financial
condition and results of operations.

DEPENDENCE UPON INDEPENDENT SHIPPING COMPANIES.

         The Company relies heavily on arrangements with independent shipping
companies for the delivery of its products. In order to meet customer demand,
products are shipped from suppliers through independent shipping companies.
Currently, Federal Express ("FedEx") and Airborne Express ("Airborne") deliver
the substantial majority of the Company's products to its customers. The
termination of the Company's relationship with FedEx and/or Airborne, or the
failure of one or more other independent shipping companies to deliver products
from suppliers to the Company or products from the Company to its customers
could have a material adverse effect on the Company's business, financial
condition or results of operations. For instance, another employee work stoppage
at United Parcel Service or an employee work stoppage or slow-down at one or
more independent shipping company could materially impair the shipping company's
ability to perform the services required by the Company. There can be no
assurance that the services of these independent shipping companies will
continue to be available to the Company on terms as favorable as those currently
available or that these companies will choose or be able to perform the required
shipping services for the Company.

RISKS CONCERNING YEAR 2000

         The Year 2000 problem concerns the inability of certain computer
systems to appropriately recognize the year 2000 when the last two digits of the
year are entered in the date field. The Company has assessed its Year 2000
requirements and believes the resources required to make its major computer
systems and programs Year 2000 compliant are immaterial. The Company, however,
could be adversely affected by the Year 2000 problem if computer systems of
third parties such as banks, suppliers and others with which the Company does
business fail to address the Year 2000 problem successfully. There can be no
assurance that the Year 2000 problem, if experienced by such third parties, will
not have a material adverse effect upon the Company's business, operating
results and financial condition.


                                      -21-
<PAGE>   23

         Many companies may need to modify or upgrade their information systems
to address the Year 2000 problem. The effects of this issue and of the efforts
by other companies to address it are unclear. The Company believes that the
purchasing patterns of customers and prospective customers might be affected by
Year 2000 issues. Many companies are expending significant resources to correct
their current software systems for Year 2000 compliance. These expenditures
might result in reduced funds available to purchase services and products such
as those offered by the Company.

NONPAYMENT OF DIVIDENDS.

         The Company has never declared or paid dividends on Common Stock and
does not anticipate paying dividends on Common Stock at any time in the
foreseeable future. The terms of certain of the Company's loan agreements and
the Certificate of Designation for Series A Stock restrict the payment of
dividends on Common Stock.

ENVIRONMENTAL REGULATION

         The Company's operations and manufacturing processes are subject to
certain federal, state, local and foreign environmental protection laws and
regulations. Public attention has increasingly been focused on the environmental
impact of manufacturing operations that use hazardous materials or generate
hazardous wastes, and environmental laws and regulations may become more
stringent over time. There can be no assurance that failure to comply with
either present or future regulations, or to obtain all necessary permits
required under such regulations, would not subject the Company to significant
compliance expenses, production suspensions or delay, restrictions on expansion
at its present or future locations, the acquisition of costly equipment or other
liabilities.

                 DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

         This Prospectus contains certain "forward-looking statements" within
the meaning of Section 27A of the Securities Act and Section 21E of the Exchange
Act. Specifically, all statements other than statements of historical facts
included in this report regarding the Company's financial position, business
strategy and plans and objectives of management of the Company for future
operations are forward-looking statements. These forward-looking statements are
based on the beliefs of the Company's management, as well as assumptions made by
and information currently available to the Company's management. When used in
this report, the words "anticipate," "believe," "estimate," "expect" and
"intend" and words or phrases of similar import, as they relate to the Company
or Company management, are intended to identify forward-looking statements. Such
statements reflect the current view of the Company with respect to future events
and are subject to certain risks, uncertainties and assumptions related to
certain factors including, without limitation, competitive factors, general
economic conditions, customer relations, relationships with vendors, the
interest rate environment, governmental regulation and supervision, product
introductions and acceptance, technological change, changes in industry
practices, one-time events and other factors described herein ("cautionary
statements"). Although the Company believes that its expectations are
reasonable, it can give no assurance that such expectations will prove to be
correct. Based upon changing conditions, should any one or more of these risks
or uncertainties materialize, or should any underlying assumptions prove
incorrect, actual results may vary materially from those described herein as
anticipated, believed, estimated, expected or intended. All subsequent written
and oral forward-looking statements attributable to the Company or persons
acting on its behalf are expressly qualified in their entirety by the applicable
cautionary statements. The Company does not intend to update these
forward-looking statements.

                                 USE OF PROCEEDS

         The Shares to be sold pursuant to the Prospectus are beneficially owned
by stockholders (the "Selling Stockholders") of the Company. The Company will
not receive any of the proceeds from the sale of the Shares. See "Selling
Stockholders."

                              SELLING STOCKHOLDERS

         The following table sets forth the name of the Selling Stockholders
and, as of August 5, 1998, the beneficial ownership of Common Stock held by the
Selling Stockholders, immediately prior to and upon completion of this offering.
The Shares are being registered hereby on behalf of the Selling Stockholders,
who may offer them for resale. See "Plan of Distribution." All information as to
beneficial ownership has been furnished by or on behalf of the Selling
Stockholders. The number of Shares that may be actually sold by the Selling
Stockholders will be determined by each Selling Stockholder, and may depend upon
a number of factors, including, among other things, the market price of the
Common Stock. Because each Selling Stockholder may offer all, some or none of
the Shares that it holds, and because the offering contemplated by this
Prospectus is currently not being underwritten, no estimate can be given as to
the number of Shares that will be held by each Selling Stockholder upon or prior
to the termination of this offering. See "Plan of Distribution." Except as
otherwise specified, each Selling Stockholder has sole voting and investment
power over the shares listed. Except as set forth below, no Selling Stockholder
has had a material relationship with the Company or any of its predecessors or
affiliates within the past three years.

(1)      Assumes all shares of Common Stock offered hereby are sold.

(2)      Based on 20,729,714 shares of Common Stock outstanding as of August 12,
         1998.
 
(3)      Includes shares of Common Stock issuable upon (i) the conversion of
         Series A Stock and the payment of dividends to be made on September 30,
         1998 on Series A Stock in the form of shares of Common Stock, in each
         case at an assumed conversion price of $1.63 and (ii) exercise of the
         Warrants issued to such Selling Stockholder. Because the number of
         shares of Common Stock issuable upon conversion of Series A Stock and
         as payment of dividends thereon is dependent in part upon the market
         price of the Common Stock prior to conversion, the actual number of
         shares of Common Stock that will be issued in respect of such
         conversions or dividend payments, and consequently the number of shares
         of Common Stock that will be beneficially owned by such Selling
         Stockholder, will fluctuate daily and cannot be determined at this
         time. Such Selling Stockholder has, however, contractually agreed to
         restrict its ability to convert shares of Series A Stock (and receive
         shares of Common Stock in payment of dividends thereon) to the extent
         that the number of shares of Common Stock held by it and its affiliates
         after such conversion exceeds 4.999% of the then issued and outstanding
         shares of Common Stock following such conversion. Due to this
         restriction, the number of shares of Common Stock beneficially owned by
         such Selling Stockholder is equal to 4.999% of the total shares of
         Common Stock outstanding. In the event the Company achieves certain
         revenue thresholds, the number of shares of Series A Stock that may be
         converted by such Selling Stockholder each month will be limited.

(4)      Includes shares of Common Stock reflected herein as beneficially owned
         by such Selling Stockholder. Because the number of shares of Common
         Stock issuable upon conversion of Series A Stock and as payment 


                                      -24-

<PAGE>   26

         of dividends thereon is dependent in part upon the market price of the
         Common Stock prior to a conversion, the actual number of shares of
         Common Stock that will be issued in respect of such conversions or
         dividend payments and, consequently, offered for sale under this
         Registration Statement, cannot be determined at this time. In order to
         provide a cushion for any such fluctuations, the Company has
         contractually agreed to include herein 200% of the number of shares of
         Common Stock as would be issuable upon conversion in full of Series A
         Stock (plus payment of dividends for two years in the form of shares of
         Common Stock), assuming such conversion occurred on August 13, 1998,
         plus the number of shares of Common Stock as would be issuable upon
         exercise in full of the Warrants issued to the Selling Stockholders.

(5)      Includes shares of Common Stock issuable upon exercise of a warrant
         dated June 30, 1998 granted by the Company to such Selling Stockholder.

         Pursuant to a Convertible Preferred Stock Purchase Agreement dated
June 30, 1998 (the "Purchase Agreement") between the Company and KA Investments
LDC, a Cayman Islands corporation ("KA Investments"), the Company issued 400
shares of its 5% Series A Convertible Preferred Stock, par value $1.00 per share
("Series A Stock"), for an aggregate purchase price of $4,000,000. The Series A
Stock is convertible into shares of Common Stock pursuant to a formula based
upon the Conversion Price, which shall be equal to the lower of either (a) $2.31
per share or (b) 80% of the average of the three lowest closing bid prices per
share of Common Stock for the 30 trading days immediately prior to conversion
(as more fully described in the Articles of Incorporation of the Company).
Dividends accrue on the Series A Stock at a rate of 5% per annum, and may be
paid in shares of Common Stock, but must be paid in cash upon the occurrence of
certain events. The Company is required to redeem certain of the shares of
Series A Stock upon the occurrence of certain triggering events. In addition,
the Company granted warrants (the "Warrants") to KA Investments, Midori Capital
Corporation ("Midori"), Hoth Incorporated ("Hoth") and Randy Stein ("Stein") (KA
Investments, Midori, Hoth and Stein collectively referred to herein as the
"Selling Stockholders") to purchase an aggregate of approximately 200,000 shares
of Common Stock at a purchase price of $3.00 per share (subject to adjustment as
provided by the terms of the Warrants). The Warrants may be exercised on or
before June 30, 2002. Pursuant to a Registration Rights Agreement between the
Company and KA Investments dated June 30, 1998, the Company granted the Selling
Stockholders certain registration rights related to the shares of Common Stock
issuable upon conversion of the Series A Stock and upon the exercise of the
Warrants. The Registration Statement to which this Prospectus is a part has been
filed pursuant to the terms of such Registration Rights Agreement and registers
the resale by the Selling Stockholders of such shares of Common Stock issuable
upon conversion of the Series A Stock and upon exercise of the Warrants. Each of
the Purchase Agreement, the Registration Rights Agreement, a form of the
Warrants and the Articles of Incorporation of the Company, as amended
(containing the terms of the Series A Stock) have been filed as exhibits to the
Registration Statement to which this Prospectus is a part.


                              PLAN OF DISTRIBUTION

         The Company is registering the Shares on behalf of the Selling
Stockholders. The Company will bear all costs, expenses and fees incident to
their registration, including certain fees and disbursements of counsel to the
Selling Stockholders. Brokerage commissions, if any, attributable to the sale of
Shares will be borne by the Selling Stockholders (or their pledgees, donees,
transferees or other successors-in-interest).

         The Company will receive no portion of the proceeds of the sale of the
Shares offered hereby. However, certain of the shares of Common Stock offered
hereby are issuable in the future upon the exercise of Warrants and the Company
will receive the exercise prices payable on any exercise of such Warrants. There
can be no assurance that all or any part of the Warrants will be exercised.

         All or a portion of the Shares may be sold from time to time by or for
the account of the Selling Stockholders, their pledgees, donees, transferees or
other successors-in-interest in the over-the-counter market, on the NASDAQ
SmallCap Market or otherwise in privately negotiated transactions or otherwise,
at fixed prices that may be changed, at market prices prevailing at the time of
sale, at prices related to such market prices or at negotiated prices. The
Shares may be sold by any one or more of the following methods, without
limitation: (a) block trade(s) in which the broker or dealer so engaged will
attempt to sell the Shares as agent but may position and resell a portion of the
block as principal to facilitate the transaction; (b) purchases by a broker or
dealer as principal and resale by such broker or dealer for its account pursuant
to this Prospectus; (c) an exchange distribution in accordance with the rules of
The 

                                      -25-

<PAGE>   27

Nasdaq SmallCap Market or applicable exchange; (d) ordinary brokerage
transactions and transactions in which the broker solicits purchasers; (e)
privately negotiated transactions; (f) short sales; (g) a combination of any
such methods of sale; and (h) any other method permitted pursuant to applicable
law.

         From time to time the Selling Stockholders may engage in short sales,
short sales against the box, puts and calls and other transactions in securities
of the Company or derivatives thereof, and may sell and deliver the Shares in
connection therewith or in settlement of securities loans. If the Selling
Stockholders engage in such transactions, the applicable conversion price may be
affected. From time to time, the Selling Stockholders may pledge their Shares
pursuant to the margin provisions of their respective customer agreements with
their respective brokers. Upon a default by any such Selling Stockholder, such
broker(s) may offer and sell the pledged Shares from time to time.

         In effecting sales, brokers and dealers engaged by any of the Selling
Stockholders may arrange for other brokers or dealers to participate in such
sales. Brokers or dealers may receive commissions or discounts from the Selling
Stockholders (or, if any such broker-dealer acts as agent for the purchaser of
such sales, from such purchaser) in amounts to be negotiated, which are not
expected to exceed those customary in the types of transactions involved.
Broker-dealers may agree with the Selling Stockholders to sell a specified
number of such Shares at a stipulated price per share, and, to the extent such
broker-dealer is unable to do so acting as agent for a Selling Stockholder, to
purchase as principal any unsold Shares at the price required to fulfill the
broker-dealer commitment to the Selling Stockholders. Broker-dealers who acquire
Shares as principal may thereafter resell such Shares from time to time in
transactions (which may involve block transactions and sales to and through
other broker-dealers, including transactions of the nature described above) in
the over-the-counter market or otherwise at prices and on terms prevailing at
the time of sale, at prices related to the then-current market price or in
negotiated transactions and, in connection with such resales, may pay to or
receive from the purchasers of such Shares commissions as described above. The
Selling Stockholders also may sell the Shares in accordance with Rule 144 under
the Securities Act, rather than pursuant to this Prospectus. The Selling
Stockholders will act independently of the Company in making decisions with
respect to the timing, manner and size of each sale. To the Company's knowledge,
no Selling Stockholder has entered into any agreement, understanding or
arrangement with any underwriter or broker-dealer regarding the sale of the
Shares, nor does the Company know the identity of the brokers or market makers,
if any, which will participate in the offering. The Selling Stockholders and any
broker-dealers or agents that participate with the Selling Stockholders in sales
of the Shares may be deemed to be "underwriters" within the meaning of the
Securities Act in connection with such sales. In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of the
Shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act. Because the Selling Stockholders each may be
deemed to be an "underwriter" within the meaning of Section 2(11) of the
Securities Act, the Selling Stockholders will be subject to prospectus delivery
requirements under the Securities Act. Furthermore, the Selling Stockholders,
any broker or dealer and any "affiliated purchasers" will be subject to the
applicable provisions of the Exchange Act and the Securities Act and the rules
and regulations thereunder, including, without limitation, Regulation M under
the Exchange Act, which provisions may limit the timing of the purchases and
sales of the Company's securities by any Selling Stockholder, any broker or
dealer and any "affiliated purchasers."

         The Company has agreed to exercise its best efforts to keep the
Registration Statement to which this Prospectus is a part continuously effective
for a maximum three years.

         The Company has agreed to indemnify the Selling Stockholders against
certain losses, claims, damages and liabilities, including liabilities under the
Securities Act. The Company has been advised that in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.


                                  LEGAL MATTERS

         The validity of the securities offered hereby will be passed upon for
the Company by Fulbright & Jaworski L.L.P., San Antonio, Texas.

ITEM 15.    INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Company's Bylaws provide that the Company shall indemnify any and
all persons who may serve or who have served at any time as directors or
officers, or who at the request of the Board of Directors of the Company may
serve or at any time have served as directors or officers of another corporation
in which the Company at such time owned or may own shares of stock or of which
it was or may be a creditor, and their respective heirs, administrators,
successors and assigns, against any and all expenses, including amounts paid
upon judgments, counsel fees and amounts paid in settlement (before or after
suit is commenced), actually and necessarily incurred by such persons in
connection with the defense or settlement of any claim, action, suit or
proceeding in which they, or any of them, are made parties, or a party, or which
may be asserted against them or any of them by reason of being or having been
directors or officers or a director or officer of the Company, or of such other
corporation, except in relation to matters as to which any such director or
officer or former director or officer or person shall be adjudged in any action,
suit or proceeding to be liable for his own negligence or misconduct in the
performance of his duty. Such indemnification shall be in addition to any other
rights to which those indemnified may be entitled under any law, bylaw,
amendment, vote of stockholders or otherwise.

LIMITATION OF LIABILITY

         Article 12 of the Articles of Incorporation provides that no director
shall be personally liable to the Company or any stockholder for monetary
damages for breach of fiduciary duty as a director, except for any matter in
respect of which such director shall be liable under Section 17-16-834 of the
Wyoming Business Company Act (the "WBCA") or any amendment thereto or successor
provision thereto, or shall be liable by reason that, in addition to any and all
other requirements for such liability, he (i) shall have breached his duty of
loyalty to the Company or its stockholders, (ii) shall not have acted in good
faith or, in failing to act, shall not have acted in good faith, (iii) shall
have acted in a manner involving intentional misconduct or a knowing violation
of law or, in failing to act, shall have acted in a manner involving intentional
misconduct or a knowing violation of law, (iv) shall have derived an improper
personal benefit or (v) shall have voted for or assented to a distribution made
in violation of Section 17-16-640 of the WBCA or the Articles of Incorporation
of the Company if it is established that he did not perform his duties in
compliance with Section 17-16-830 of the WBCA.

         This provision may have the effect of reducing the likelihood of
derivative litigation against directors and may discourage or deter stockholders
or management from bringing a lawsuit against directors for breach of their duty
of care, even though such an action, if successful, might otherwise have
benefitted the Company and its stockholders. However, this provision, together
with the provision described above that requires the Company to indemnify its
officers and directors against certain liabilities, is intended to enable the
Company to attract qualified persons to serve as directors who might otherwise
be reluctant to do so.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 as Amended (the "Securities Act") may be permitted to directors,
officers or persons controlling the Company pursuant to the foregoing
provisions, the Company has been informed that in the opinion of the Commission,
such indemnification is against public policy as expressed in the Securities Act
and is therefore unenforceable.

ITEM 17.        UNDERTAKINGS.

         (a) The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement to include any
material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement;

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment 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; and

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the registration
statement 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.

         (c) The undersigned registrant hereby undertakes that, 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 Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the

                                      II-2

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 "Securities Act"), the Registrant certifies that it has reasonable grounds

for attendance at each meeting of the board of directors or a stated salary as
director. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

Removal of Directors

by-laws, any director or the entire board of directors may be removed, with or

                            TERMS OF PREFERRED STOCK

        Section 1. Designation, Amount and Par Value. The series of preferred
stock shall be designated as 5% Series A Convertible Preferred Stock (the
"Preferred Stock") and the number of shares so designated shall be 400 (which
shall not be subject to increase without the consent of the holders of the
Preferred Stock (each, a "Holder" and collectively, the "Holders")); Each share
of Preferred Stock shall have a par value of $1.00 and a stated value of $10,000
(the "Stated Value").

        Section 2. Dividends.

        (a) Holders shall be entitled to receive, when and as declared by the
Board of Directors out of funds legally available therefor, and the Company
shall pay, cumulative dividends at the rate per share (as a percentage of the
Stated Value per share) equal to 5% per annum, payable on a quarterly basis on
March 31, June 30, September 30 and December 31 of each year during the term
hereof (each a "Dividend Payment Date"), commencing on September 30, 1998, in
cash or shares of Common Stock (as defined in Section 8) at, subject to the
terms and conditions set forth herein, the option of the Company. Dividends on
the Preferred Stock shall be calculated on the basis of a 360-day year, shall
accrue daily commencing on the Original Issue Date (as defined in Section 8),
and shall be deemed to accrue from such date whether or not earned or declared
and whether or not there are profits, surplus or other funds of the Company
legally available for the payment of dividends. Any dividends not paid on any
Dividend Payment Date shall continue to accrue and shall be due and payable upon
conversion of the Preferred Stock. A party that holds shares of Preferred Stock
on a Dividend Payment Date will be entitled to receive such dividend payment and
any other accrued and unpaid dividends which accrued prior to such Dividend
Payment Date, without regard to any sale or disposition of such Preferred Stock
subsequent to the applicable record date. All overdue accrued and unpaid
dividends and other amounts due herewith shall entail a late fee at the rate of
15% per annum (to accrue daily, from the date such dividend is due hereunder
through and including the date of payment). Except as otherwise provided herein,
if at any time the Company pays less than the total amount of dividends then
accrued on account of the Preferred Stock, such payment shall be distributed
ratably among the Holders based upon the number of shares held by each Holder.
Payment of dividends on the Preferred Stock is further subject to the provisions
of Section 5(c)(i). The Company shall provide the Holders notice of its
intention to pay dividends in cash or shares of Common Stock not less than 10
Trading Days prior to any Dividend Payment Date for so long as shares of
Preferred Stock are outstanding. If dividends are paid in shares of Common
Stock, the number of shares of Common Stock issuable on account of such dividend
shall equal the cash amount of such dividend on such Dividend Payment Date
divided by the Conversion Price (as defined below) on such date.



<PAGE>   25

        (b) Notwithstanding anything to the contrary contained herein, the
Company may not issue shares of Common Stock in payment of dividends on the
Preferred Stock (and must deliver cash in respect thereof) if:

            (i) the number of shares of Common Stock at the time authorized,
unissued and unreserved for all purposes is insufficient to pay such dividends
in shares of Common Stock;

            (ii) such shares of Common Stock are not registered for resale
pursuant to an effective registration statement that names the recipient of such
dividend as a selling stockholder thereunder and may not be sold without volume
restrictions pursuant to Rule 144 promulgated under the Securities Act of 1933,
as amended (the "Securities Act"), as determined by counsel to the Company
pursuant to a written opinion letter, addressed to the Company's transfer agent
in the form and substance acceptable to the Holders and such transfer agent;

            (iii) the Common Stock is not then listed or quoted on the Nasdaq
SmallCap Market ("NASDAQ") or on the New York Stock Exchange, American Stock
Exchange or the Nasdaq National Market (each, a "Subsequent Market");

            (iv) the Company has failed to timely satisfy its conversion
obligations hereunder; or

            (v) the issuance of such shares of Common Stock would result in the
recipient thereof beneficially owning, as determined in accordance with Rule
13d-3 promulgated under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), more than 4.999% of the then issued and outstanding shares of
Common Stock.

        (c) So long as any Preferred Stock shall remain outstanding, neither the
Company nor any subsidiary thereof shall redeem, purchase or otherwise acquire
directly or indirectly any Junior Securities (as defined in Section 8), nor
shall the Company directly or indirectly pay or declare any dividend or make any
distribution (other than a dividend or distribution described in Section 5)
upon, nor shall any distribution be made in respect of, any Junior Securities,
nor shall any monies be set aside for or applied to the purchase or redemption
(through a sinking fund or otherwise) of any Junior Securities or shares pari
passu with the Preferred Stock, except for repurchases effected by the Company
on the open market, pursuant to a direct stock purchase plan.

        Section 3. Voting Rights. Except as otherwise provided herein and as
otherwise required by law, the Preferred Stock shall have no voting rights.
However, so long as any shares of Preferred Stock are outstanding, the Company
shall not and shall cause its subsidiaries not to, without the affirmative vote
of the Holders of all of the shares of the Preferred Stock then outstanding, (a)
alter or change adversely the powers, preferences or rights given to the
Preferred Stock, (b) alter or amend this Certificate of Designation, (c)
authorize or create any class of stock ranking as to dividends or distribution
of assets upon a Liquidation (as defined in Section 4) senior to or otherwise
pari passu with or senior to the Preferred Stock, except for any series of
Preferred Stock issued and sold in accordance with the Purchase Agreement, (d)
amend its Certificate of Incorporation, bylaws or other charter documents so as
to affect adversely any rights of any Holders,


                                      -2-
<PAGE>   26
(e) increase the authorized number of shares of Preferred Stock, or (f) enter
into any agreement with respect to the foregoing.

        Section 4. Liquidation. Upon any liquidation, dissolution or winding-up
of the Company, whether voluntary or involuntary (a "Liquidation"), the Holders
shall be entitled to receive out of the assets of the Company, whether such
assets are capital or surplus, for each share of Preferred Stock an amount equal
to the Stated Value plus all due but unpaid dividends per share, whether
declared or not, before any distribution or payment shall be made to the holders
of any Junior Securities, and if the assets of the Company shall be insufficient
to pay in full such amounts, then the entire assets to be distributed to the
Holders shall be distributed among the Holders ratably in accordance with the
respective amounts that would be payable on such shares if all amounts payable
thereon were paid in full. A sale, conveyance or disposition of all or
substantially all of the assets of the Company or the effectuation by the
Company of a transaction or series of related transactions in which more than
33% of the voting power of the Company is disposed of, or a consolidation or
merger of the Company with or into any other company or companies shall not be
treated as a Liquidation, but instead shall be subject to the provisions of
Section 5. The Company shall mail written notice of any such Liquidation, not
less than 45 days prior to the payment date stated therein, to each record
Holder.

        Section 5. Conversion.

        (a)(i) Conversions at Option of Holder. Each share of Preferred Stock
shall be convertible into shares of Common Stock (subject to the limitations set
forth in Section 5(a)(ii) hereof) at the Conversion Ratio (as defined in Section
8) at the option of the Holder, at any time and from time to time, from and
after the 90th day following the Original Issue Date (the "Initial Conversion
Date"). From and after the Initial Conversion Date until the 240th day following
the Original Issue Date, the Holders may convert each month on a cumulative
basis such number of shares of Preferred Stock as is equal to or less than the
Initial Conversion Amount (for example, if no conversion is made prior to the
3rd month after the Initial Conversion Date, then the Holders may convert 3
times the Initial Conversion Amount on the first day of the 3rd month after the
Initial Conversion Date) so long as the total revenues generated by the Company
as reported on the Company's Form 10-Q filed with the Securities and Exchange
Commission (the "Commission") for (i) the quarter ended June 30, 1998 are equal
to or in excess of $6,000,000, (ii) the quarter ended September 30, 1998 are
equal to or in excess of $9,000,000 and (iii) the quarter ended December 31,
1998 are equal to or less than $9,000,000 (the revenue amounts set forth in
clauses (i), (ii) and (iii) called, the "Revenue Targets"). Notwithstanding the
foregoing, the conversion limitations set forth in this Section shall
immediately cease to apply, and the Holders shall be entitled to convert all or
any of the Preferred Stock from time to time thereafter, if the Company fails to
timely file with the Commission a Form 10-Q that meets the Revenue Target
applicable to such Form 10-Q. Holders shall effect conversions by surrendering
the certificate or certificates representing the shares of Preferred Stock to be
converted to the Company, together with the form of conversion notice attached
hereto as Exhibit 1 (a "Conversion Notice"). Each Conversion Notice shall
specify the number of shares of Preferred Stock to be converted and the date on
which such conversion is to be effected, which date may not be prior to the date
the Holder delivers such Conversion Notice by facsimile (the "Conversion Date").
If no Conversion Date is specified in a Conversion Notice, the


                                      -3-
<PAGE>   27

Conversion Date shall be the date that the Conversion Notice is deemed delivered
hereunder. If the Holder is converting less than all shares of Preferred Stock
represented by the certificate or certificates tendered by the Holder with the
Conversion Notice, or if a conversion hereunder cannot be effected in full for
any reason, the Company shall promptly deliver to such Holder (in the manner and
within the time set forth in Section 5(b)) a certificate for such number of
shares as have not been converted.

            (ii) Certain Conversion Restrictions.

            (A) The Holder agrees not to convert shares of Preferred Stock to
the extent such conversion would result in the Holder beneficially owning (as
determined in accordance with Section 13(d) of the Exchange Act and the rules
thereunder) in excess of 4.999% of the then issued and outstanding shares of
Common Stock, including shares issuable upon conversion of the shares of
Preferred Stock held by such Holder after application of this Section. To the
extent that the limitation contained in this Section applies, the determination
of whether shares of Preferred Stock are convertible (in relation to other
securities owned by a Holder) and of which shares of Preferred Stock are
convertible shall be in the sole discretion of the Holder, and the submission of
shares of Preferred Stock for conversion shall be deemed to be the Holder's
determination of whether such shares of Preferred Stock are convertible (in
relation to other securities owned by the Holder) and of which portion of such
shares of Preferred Stock are convertible, in each case subject to such
aggregate percentage limitation, and the Company shall have no obligation to
verify or confirm the accuracy of such determination. Nothing contained herein
shall be deemed to restrict the right of the Holder to convert shares of
Preferred Stock at such time as such conversion will not violate the provisions
of this Section. The provisions of this Section may be waived by a Holder (but
only as to itself and not to any other Holder) upon not less than 75 days prior
notice to the Company (in which case, the Holder shall make such filings with
the Commission, including under Rule 13D or 13G, as are required by applicable
law), and the provisions of this Section shall continue to apply until such 75th
day (or later, if stated in the notice of waiver). Other Holders shall be
unaffected by any such waiver.

            (B) If on any Conversion Date (1) the Common Stock is listed for
trading on the NASDAQ or the Nasdaq National Market, (2) the Conversion Price
then in effect is such that the aggregate number of shares of Common Stock that
would then be issuable upon conversion in full of all then outstanding shares of
Preferred Stock, together with any shares of the Common Stock previously issued
upon conversion of the shares of Preferred Stock and as payment of dividends
thereon, would equal or exceed 20% of the number of shares of the Common Stock
outstanding on the Original Issue Date (such number of shares as would not equal
or exceed such 20% limit, the "Issuable Maximum"), and (3) the Company shall not
have previously obtained the vote of shareholders (the "Shareholder Approval"),
if any, as may be required by the rules and regulations of The Nasdaq Stock
Market (or successor thereto) applicable to approve the issuance of Common Stock
in excess of the Issuable Maximum in a private placement whereby shares of
Common Stock are deemed to have been issued at a price that is less than the
greater of book or fair market value of the Common Stock, then the Company shall
issue to the Holder so requesting a conversion a number of shares of Common
Stock equal to the Issuable Maximum and, with respect to the remainder of the
aggregate Stated Value of the shares of Preferred Stock then held by such Holder


                                      -4-
<PAGE>   28

for which a conversion in accordance with the Conversion Price would result in
an issuance of Common Stock in excess of the Issuable Maximum (the "Excess
Stated Value"), the converting Holder shall have the option to require the
Company to either (a) use its best efforts to obtain the Shareholder Approval
applicable to such issuance as soon as is possible, but in any event not later
than the 60th day after such request, or (b)(i) issue and deliver to such Holder
a number of shares of Common Stock as equals (x) the Excess Stated Value, plus
accrued dividends on all shares of Preferred Stock being converted, divided by
(y) the closing sales price of the Common Stock on the Original Issue Date, and
(ii) cash in an amount equal to the product of (x) the Per Share Market Value on
the Conversion Date and (y) the number of shares of Common Stock in excess of
such Holder's pro rata portion of the Issuable Maximum that would have otherwise
been issuable to the Holder in respect of such conversion but for the provisions
of this Section (such amount of cash being hereinafter referred to as the
"Discount Equivalent"), or (c) pay cash to the converting Holder in an amount
equal to the Mandatory Redemption Amount (as defined in Section 8) for the
Excess Stated Value. If the Company fails to pay the Discount Equivalent or the
Mandatory Redemption Amount, as the case may be, in full pursuant to this
Section within seven (7) days after the date payable, the Company will pay
interest thereon at a rate of 15% per annum to the converting Holder, accruing
daily from the Conversion Date until such amount, plus all such interest
thereon, is paid in full.

            (b) (i) Not later than three (3) Trading Days after any Conversion
Date, the Company will deliver to the Holder (i) a certificate or certificates
which shall be free of restrictive legends and trading restrictions (other than
those required by Section 3.1(b) of the Purchase Agreement) representing the
number of shares of Common Stock being acquired upon the conversion of shares of
Preferred Stock (subject to the limitations set forth in Section 5(a)(ii)
hereof), (ii) one or more certificates representing the number of shares of
Preferred Stock not converted, (iii) a bank check in the amount of accrued and
unpaid dividends (if the Company has elected to pay accrued dividends in cash),
and (iv) if the Company has elected and is permitted hereunder to pay accrued
dividends in shares of Common Stock, certificates, which shall be free of
restrictive legends and trading restrictions (other than those required by
Section 3.1 (b) of the Purchase Agreement), representing such shares of Common
Stock; provided, however, that the Company shall not be obligated to issue
certificates evidencing the shares of Common Stock issuable upon conversion of
any shares of Preferred Stock until certificates evidencing such shares of
Preferred Stock are either delivered for conversion to the Company or any
transfer agent for the Preferred Stock or Common Stock, or the Holder of such
Preferred Stock notifies the Company that such certificates have been lost,
stolen or destroyed and provides a bond (or other adequate security) reasonably
satisfactory to the Company to indemnify the Company from any loss incurred by
it in connection therewith. The Company shall, upon request of the Holder, if
available, use its best efforts to deliver any certificate or certificates
required to be delivered by the Company under this Section electronically
through the Depository Trust Corporation or another established clearing
corporation performing similar functions. If in the case of any Conversion
Notice such certificate or certificates, including for purposes hereof, any
shares of Common Stock to be issued on the Conversion Date on account of accrued
but unpaid dividends hereunder, are not delivered to or as directed by the
applicable Holder by the third (3rd) Trading Day after the Conversion Date, the
Holder shall be entitled by written notice to the Company at any time on or
before its receipt of such certificate or certificates thereafter,


                                      -5-
<PAGE>   29

to rescind such conversion, in which event the Company shall immediately return
the certificates representing the shares of Preferred Stock tendered for
conversion.

               (ii) If the Company fails to deliver to the Holder such
certificate or certificates pursuant to Section 5(b)(i), including for purposes
hereof, any shares of Common Stock to be issued on the Conversion Date on
account of accrued but unpaid dividends hereunder, by the third (3rd) Trading
Day after the Conversion Date, the Company shall pay to such Holder, in cash, as
liquidated damages and not as a penalty, $5,000 for each day after such third
(3rd) Trading Day until such certificates are delivered. Nothing herein shall
limit a Holder's right to pursue actual damages for the Company's failure to
deliver certificates representing shares of Common Stock upon conversion within
the period specified herein and such Holder shall have the right to pursue all
remedies available to it at law or in equity including, without limitation, a
decree of specific performance and/or injunctive relief. The exercise of any
such rights shall not prohibit the Holders from seeking to enforce damages
pursuant to any other Section hereof or under applicable law. Further, if the
Company shall not have delivered any cash due in respect of conversions of
Preferred Stock or as payment of dividends thereon by the third (3rd) Trading
Day after the Conversion Date, the Holder may, by notice to the Company, require
the Company to issue Underlying Shares pursuant to Section 5(c), except that for
such purpose the Conversion Price applicable thereto shall be the lesser of the
Conversion Price on the Conversion Date and the Conversion Price on the date of
such Holder demand. Any such Underlying Shares will be subject to the provision
of this Section.

               (iii) In addition to any other rights available to the Holder, if
the Company fails to deliver to the Holder such certificate or certificates
pursuant to Section 5(b)(i), including for purposes hereof, any shares of Common
Stock to be issued on the Conversion Date on account of accrued but unpaid
dividends hereunder, by the third (3rd) Trading Day after the Conversion Date,
and if after such third (3rd) Trading Day the Holder purchases (in an open
market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by such Holder of the Underlying Shares which the Holder
anticipated receiving upon such conversion (a "Buy-In"), then the Company shall
pay in cash to the Holder (in addition to any remedies available to or elected
by the Holder) the amount by which (x) the Holder's total purchase price
(including brokerage commissions, if any) for the shares of Common Stock so
purchased exceeds (y) the aggregate stated value of the shares of Preferred
Stock for which such conversion was not timely honored. For example, if the
Holder purchases shares of Common Stock having a total purchase price of $11,000
to cover a Buy-In with respect to an attempted conversion of $10,000 aggregate
stated value of the shares of Preferred Stock, the Company shall be required to
pay the Holder $1,000. The Holder shall provide the Company written notice
indicating the amounts payable to the Holder in respect of the Buy-In.

        (c)(i) The conversion price for each share of Preferred Stock (the
"Conversion Price") in effect on any Conversion Date shall be the lesser of (a)
$2.31 (the "Initial Conversion Price") and (b) 80% (the "Discount Price")
multiplied by the average of the three (3) lowest Per Share Market Values (as
defined in Section 8) during the thirty (30) Trading Days immediately preceding
the applicable Conversion Date; provided, however, that such thirty (30) Trading
Day period shall be extended for the number of Trading Days during such period
in which (A) trading in the Common Stock was suspended on the NASDAQ or on such
Subsequent Market on which the Common Stock


                                      -6-
<PAGE>   30

is then listed, or (B) after the date declared effective by the Commission, the
Underlying Securities Registration Statement is not effective, or (C) after the
date declared effective by the Commission, the Prospectus included in the
Underlying Securities Registration Statement may not be used by the Holder for
the resale of Underlying Shares; provided further, that prior to the 240th day
following the Original Issue Date, the Conversion Price may not be less than the
Floor (as defined in Section 8), except that (i) the Floor shall immediately
cease to apply if the Company fails to timely file with the Commission a Form
10-Q that meets the Revenue Target applicable to such Form 10-Q described in
Section 5(a)(i) and (ii) the Floor shall not apply to (and shall be lowered in
accordance with subparagraph (D) below) any adjustments of the Conversion Price
pursuant to subparagraph (D) below or to adjustments to the Conversion Price as
a result of the provisions of Section 5(c)(ii)-(v).


            (A) If an Underlying Securities Registration Statement is not filed
on or prior to the Filing Date (as defined in the Registration Rights Agreement)
(if the Company files such Underlying Securities Registration Statement without
affording the Holder the opportunity to review and comment on the same as
required by Section 3(a) of the Registration Rights Agreement, the Company shall
not be deemed to have satisfied this clause (a)), then the Company will pay to
the Holders on the calendar day immediately following the Filing Date an amount
equal to 1% of the aggregate Stated Value of the Preferred Stock purchased by
the Holders in cash as liquidated damages, and not as a penalty. Commencing on
the 60th day following the Original Issue Date, and on expiration of each
succeeding 30-day period thereafter until the Underlying Securities Registration
Statement is filed, the Company will pay to the Holders an amount equal to 3% of
the aggregate Stated Value of the Preferred Stock purchased by the Holders in
cash as liquidated damages, and not as a penalty.

            (B) If the Company fails to respond to questions or comments from
the Commission within ten (10) Business Days (as defined in the Registration
Rights Agreement) of receipt of such questions or comments (the "Response
Deadline"), the Company will pay to the Holders on the Business Day immediately
following the Response Deadline and on each of the four immediately succeeding
Business Days until the earlier to occur of the sixth Business Day immediately
following the Response Deadline or such time as a response is filed with the
Commission, an amount of $10,000 in cash as liquidated damages, and not as a
penalty. Commencing on the sixth Business Day immediately following the Response
Deadline, during every 5 Business Day period until a response is filed with the
Commission, the Company will pay to the Holders on each Business Day an amount
equal to the amount that was to be paid by the Company to the Holders on each
Business Day during the immediately preceding 5 Business Day period pursuant to
this subparagraph plus $2,500, in cash as liquidated damages, and not as a
penalty (for example, on each Business Day during the second 5 Business Day
period immediately following the Response Deadline, the Company shall pay to the
Holders $12,500 and on each Business Day during the third 5 Business Day period
immediately following the Response Deadline, the Company shall pay to the
Holders $15,000).

            (C) If the Underlying Securities Registration Statement is not
declared effective by the Commission on or prior to the Effectiveness Date (as
defined in the Registration Rights Agreement), then the Company will pay to the
Holders on January 1, 1999, an amount equal


                                      -7-
<PAGE>   31

to 1% of the aggregate Stated Value of the Preferred Stock purchased by the
Holders in cash as liquidated damages, and not as a penalty. Thereafter, on
February 1, 1999, and on the first day of each succeeding month thereafter until
the Underlying Securities Registration Statement is declared effective by the
Commission, the Company will pay to the Holders an amount equal to 3% of the
aggregate Stated Value of the Preferred Stock purchased by the Holders in cash
as liquidated damages, and not as a penalty.

             (D) If (a) the Company fails to file with the Commission a request
for acceleration in accordance with Rule 12d1-2 promulgated under the Securities
Exchange Act of 1934, as amended, within five (5) days of the date that the
Company is notified (orally or in writing, whichever is earlier) by the
Commission that an Underlying Securities Registration Statement will not be
"reviewed," or not subject to further review, or (b) such Underlying Securities
Registration Statement is filed with and declared effective by the Commission
but thereafter ceases to be effective as to all Registrable Securities at any
time prior to the expiration of the "Effectiveness Period" (as defined in the
Registration Rights Agreement), without being succeeded within ten (10) days by
a subsequent Underlying Securities Registration Statement filed with and
declared effective by the Commission, or (c) trading in the Common Stock shall
be delisted or suspended from trading on the NASDAQ or on such Subsequent Market
on which the Common Stock is then listed for more than three Trading Days (which
need not be consecutive days) or (d) an amendment to the Underlying Securities
Registration Statement is not filed by the Company with the Commission within
ten (10) days of the Commission's notifying the Company that such amendment is
required in order for the Underlying Securities Registration Statement to be
declared effective or (e) if the conversion rights of the Holders are suspended
for any reason, or (f) if the Company is required to convene a shareholders
meeting pursuant to Section 5(a)(ii)(B) and fails to convene a meeting of
shareholders within the time periods specified in Section 5(a)(ii)(B) (any such
failure or breach being referred to as an "Event," for purposes of clause (a)
the date on which such five (5) day period is exceeded, or for purposes of
clause (b) and (d) the date which such 10 day-period is exceeded, or for
purposes of clause (c) the date on which such three (3) Trading Day-period is
exceeded, being referred to as "Event Date"), the Conversion Price shall be
decreased by 3% on the Event Date and each monthly anniversary thereof until the
earlier to occur of the second month anniversary after the Event Date and such
time as the applicable Event is cured (i.e., the Conversion Price would decrease
by 3% as of the Event Date and 5% as of the one month anniversary of such Event
Date). Commencing on the second month anniversary after the Event Date, the
Holder shall have the option to either (x) require further cumulative 3%
discounts to continue or (y) require the Company to pay to the Holder 3% of the
aggregate Stated Values of the shares of Preferred Stock then held by such
Holder, in cash, as liquidated damages and not as a penalty, on the first day of
each monthly anniversary of the Event Date, until such time as the applicable
Event is cured. Any decrease in the Conversion Price pursuant to this Section
shall remain in effect notwithstanding the fact that the Event causing such
decrease has been subsequently cured and further monthly decreases have ceased.

The provisions of this Section 5 (c)(i) are not exclusive and shall in no way
limit the Company's obligations under the Registration Rights Agreement.

        (ii) If the Company, at any time while any shares of Preferred Stock are
outstanding, shall (a) pay a stock dividend or otherwise make a distribution or
distributions on shares


                                      -8-
<PAGE>   32

of its Junior Securities or pari passu securities payable in shares of Common
Stock, (b) subdivide outstanding shares of Common Stock into a larger number of
shares, (c) combine outstanding shares of Common Stock into a smaller number of
shares, or (d) issue by reclassification of shares of Common Stock any shares of
capital stock of the Company, the Initial Conversion Price shall be multiplied
by a fraction of which the numerator shall be the number of shares of Common
Stock outstanding before such event and of which the denominator shall be the
number of shares of Common Stock outstanding after such event. Any adjustment
made pursuant to this Section 5(c)(ii) shall become effective immediately after
the record date for the determination of stockholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or re-classification.

            (iii) If the Company, at any time while any shares of Preferred
Stock are outstanding, shall issue rights, warrants or options to all holders of
Common Stock entitling them to subscribe for or purchase shares of Common Stock
at a price per share less than the Per Share Market Value at the record date
mentioned below, then the Initial Conversion Price shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to the issuance of such rights, warrants or
options, plus the number of shares of Common Stock which the aggregate offering
price of the total number of shares so offered would purchase at such Per Share
Market Value, and the denominator of which shall be the sum of the number of
shares of Common Stock outstanding immediately prior to such issuance plus the
number of shares of Common Stock offered for subscription or purchase. Such
adjustment shall be made whenever such rights or warrants are issued, and shall
become effective immediately after the record date for the determination of
stockholders entitled to receive such rights or warrants. However, upon the
expiration of any right, warrant or option to purchase shares of Common Stock
the issuance of which resulted in an adjustment in the Conversion Price pursuant
to this Section 5(c)(iii), if any such right, warrant or option shall expire and
shall not have been exercised, the Conversion Price shall immediately upon such
expiration shall be recomputed and effective immediately upon such expiration
shall be increased to the price which it would have been (but reflecting any
other adjustments in the Conversion Price made pursuant to the provisions of
this Section 5 upon the issuance of other rights or warrants) had the adjustment
of the Conversion Price made upon the issuance of such rights, warrants, or
options been made on the basis of offering for subscription or purchase only
that number of shares of Common Stock actually purchased upon the exercise of
such rights, warrants or options actually exercised.

            (iv) If the Company or any subsidiary thereof, as applicable with
respect to Common Stock Equivalents (as defined below), at any time while any
shares of Preferred Stock are outstanding, shall issue shares of Common Stock or
rights, warrants, options or other securities or debt that is convertible into
or exchangeable for shares of Common Stock ("Common Stock Equivalents")
entitling any Person to acquire shares of Common Stock at a price per share less
than the Conversion Price, then the Conversion Price shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to the issuance of shares of Common Stock or such
Common Stock Equivalents plus the number of shares of Common Stock which the
offering price for such shares of Common Stock or Common Stock Equivalents would
purchase at the Conversion Price, and the denominator of which shall be the sum
of the number of shares of Common Stock outstanding immediately prior to such
issuance plus the


                                      -9-
<PAGE>   33

number of shares of Common Stock so issued or issuable, provided, that for
purposes hereof, all shares of Common Stock that are issuable upon exercise or
exchange of Common Stock Equivalents shall be deemed outstanding immediately
after the issuance of such Common Stock Equivalents. Such adjustment shall be
made whenever such shares of Common Stock or Common Stock Equivalents are
issued.

            (v) If the Company, at any time while shares of Preferred Stock are
outstanding, shall distribute to all holders of Common Stock (and not to
Holders) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security (excluding those referred to in Sections
5(c)(ii)-(iv) above), then in each such case the Initial Conversion Price at
which each share of Preferred Stock shall thereafter be convertible shall be
determined by multiplying the Initial Conversion Price in effect immediately
prior to the record date fixed for determination of stockholders entitled to
receive such distribution by a fraction of which the denominator shall be the
Per Share Market Value of Common Stock determined as of the record date
mentioned above, and of which the numerator shall be such Per Share Market Value
of the Common Stock on such record date less the then fair market value at such
record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding share of Common Stock as determined by
the Board of Directors in good faith; provided, however, that in the event of a
distribution exceeding ten percent (10%) of the net assets of the Company, if
the Holders of a majority in interest of the Preferred Stock dispute such
valuation, such fair market value shall be determined by a nationally recognized
or major regional investment banking firm or firm of independent certified
public accountants of recognized standing (which may be the firm that regularly
examines the financial statements of the Company) (an "Appraiser") selected in
good faith by the Holders of a majority in interest of the shares of Preferred
Stock then outstanding; and provided, further, that the Company, after receipt
of the determination by such Appraiser shall have the right to select an
additional Appraiser, in good faith, in which case the fair market value shall
be equal to the average of the determinations by each such Appraiser. In either
case the adjustments shall be described in a statement provided to the Holders
of the portion of assets or evidences of indebtedness so distributed or such
subscription rights applicable to one share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

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

            (vii) Whenever the Conversion Price is adjusted pursuant to Section
5(c)(i),(ii),(iii),(iv), or (v) the Company shall promptly mail to each Holder,
a notice setting forth the Conversion Price after such adjustment and setting
forth a brief statement of the facts requiring such adjustment.

            (viii) In case of any reclassification of the Common Stock, or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property (other than compulsory share exchanges which
constitute Change of Control Transactions), the Holders of the Preferred Stock
then outstanding shall have the right thereafter to convert such shares only
into the shares of stock and other securities, cash and property receivable upon
or


                                      -10-
<PAGE>   34

deemed to be held by holders of Common Stock following such reclassification or
share exchange, and the Holders of the Preferred Stock shall be entitled upon
such event to receive such amount of securities, cash or property as a holder of
the number of shares of the Common Stock of the Company into which such shares
of Preferred Stock could have been converted immediately prior to such
reclassification or share exchange would have been entitled. This provision
shall similarly apply to successive reclassifications or share exchanges.

            (ix) If (a) the Company shall declare a dividend (or any other
distribution) on its Common Stock, (b) the Company shall declare a special
nonrecurring cash dividend on or a redemption of its Common Stock, (c) the
Company shall authorize the granting to all holders of the Common Stock rights
or warrants to subscribe for or purchase any shares of capital stock of any
class or of any rights, (d) the approval of any stockholders of the Company
shall be required in connection with any reclassification of the Common Stock of
the Company, any consolidation or merger to which the Company is a party, any
sale or transfer of all or substantially all of the assets of the Company, of
any compulsory share of exchange whereby the Common Stock is converted into
other securities, cash or property, or (e) the Company shall authorize the
voluntary or involuntary dissolution, liquidation or winding up of the affairs
of the Company; then the Company shall cause to be filed at each office or
agency maintained for the purpose of conversion of Preferred Stock, and shall
cause to be mailed to the Holders at their last addresses as they shall appear
upon the stock books of the Company, at least 20 calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of Common Stock of record to be entitled to
such dividend, distributions, redemption, rights or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange; provided, however, that
the failure to mail such notice or any defect therein or in the mailing thereof
shall not affect the validity of the corporate action required to be specified
in such notice. Holders are entitled to convert shares of Preferred Stock during
the 20-day period commencing the date of such notice to the effective date of
the event triggering such notice.

            (x) If the Company (i) makes a public announcement that it intends
to enter into a Change of Control Transaction (as defined in Section 8) or (ii)
any person, group or entity (including the Company, but excluding a Holder or
any affiliate of a Holder) publicly announces a bona fide tender offer, exchange
offer or other transaction to purchase 33% or more of the Common Stock (such
announcement being referred to herein as a "Major Announcement" and the date on
which a Major Announcement is made, the "Announcement Date"), then, in the event
that a Holder seeks to convert shares of Preferred Stock on or following the
Announcement Date, the Conversion Price shall, effective upon the Announcement
Date and continuing through the earlier to occur of the consummation of the
proposed transaction or tender offer, exchange offer or other transaction and
the Abandonment Date (as defined below), be equal to the lower of (x) the
average Per Share Market Value on the five Trading Days immediately preceding
(but not including) the Announcement Date and (y) the Conversion Price that
would otherwise have been in effect on the


                                      -11-
<PAGE>   35

Conversion Date for such Preferred Stock but for the application of this
section. "Abandonment Date" means with respect to any proposed transaction or
tender offer, exchange offer or other transaction for which a public
announcement as contemplated by this paragraph has been made, the date upon
which the Company (in the case of clause (i) above) or the person, group or
entity (in the case of clause (ii) above) publicly announces the termination or
abandonment of the proposed transaction or tender offer, exchange offer or
another transaction which caused this paragraph to become operative.

        (d) The Company covenants that it will at all times reserve and keep
available out of its authorized and unissued Common Stock solely for the purpose
of issuance upon conversion of Preferred Stock and payment of dividends on
Preferred Stock, each as herein provided, free from preemptive rights or any
other actual contingent purchase rights of persons other than the Holders, not
less than such number of shares of Common Stock as shall (subject to any
additional requirements of the Company as to reservation of such shares set
forth in the Purchase Agreement) be issuable (taking into account the
adjustments and restrictions of Section 5(a) and Section 5(c)) upon the
conversion of all outstanding shares of Preferred Stock and payment of dividends
hereunder. The Company covenants that all shares of Common Stock that shall be
so issuable shall, upon issue, be duly and validly authorized, issued and fully
paid, nonassessable and freely tradeable, subject to the legend requirements of
Section 3.1 (b) of the Purchase Agreement.

        (e) Upon a conversion hereunder the Company shall not be required to
issue stock certificates representing fractions of shares of Common Stock, but
may if otherwise permitted, make a cash payment in respect of any final fraction
of a share based on the Per Share Market Value at such time. If the Company
elects not, or is unable, to make such a cash payment, the Holder of a share of
Preferred Stock shall be entitled to receive, in lieu of the final fraction of a
share, one whole share of Common Stock.

        (f) The issuance of certificates for shares of Common Stock on
conversion of Preferred Stock shall be made without charge to the Holders
thereof for any documentary stamp or similar taxes that may be payable in
respect of the issue or delivery of such certificate, provided that the Company
shall not be required to pay any tax that may be payable in respect of any
transfer involved in the issuance and delivery of any such certificate upon
conversion in a name other than that of the Holder of such shares of Preferred
Stock so converted and the Company shall not be required to issue or deliver
such certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

        (g) Shares of Preferred Stock converted into Common Stock shall be
canceled. The Company may not reissue any shares of Preferred Stock.

        (h) Any and all notices or other communications or deliveries to be
provided by the Holders of the Preferred Stock hereunder, including, without
limitation, any Conversion Notice, shall be in writing and delivered personally,
by facsimile or sent by a nationally recognized overnight courier service,
addressed to the attention of the Chief Financial Officer of the Company at the
facsimile telephone number or address of the principal place of business of the
Company as set forth


                                      -12-
<PAGE>   36

in the Purchase Agreement. Any and all notices or other communications or
deliveries to be provided by the Company hereunder shall be in writing and
delivered personally, by facsimile or sent by a nationally recognized overnight
courier service, addressed to each Holder at the facsimile telephone number or
address of such Holder appearing on the books of the Company, or if no such
facsimile telephone number or address appears, at the principal place of
business of the Holder. Any notice or other communication or deliveries
hereunder shall be deemed given and effective on the earliest of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified in this Section prior to 8:00 p.m. (Eastern
Standard Time), (ii) the date after the date of transmission, if such notice or
communication is delivered via facsimile at the facsimile telephone number
specified in this Section later than 8:00 p.m. (Eastern Standard Time) on any
date and earlier than 11:59 p.m. (Eastern Standard Time) on such date, (iii)
upon receipt, if sent by a nationally recognized overnight courier service, or
(iv) upon actual receipt by the party to whom such notice is required to be
given.

        Section 6. Optional Redemption.

        (a) So long as the Conversion Price is less than $1.50, the Company
shall have the right, exercisable at any time upon 20 Trading Days' notice (an
"Optional Redemption Notice") to the Holders of the Preferred Stock given at any
time after the Original Issue Date to redeem all or any portion of the shares of
Preferred Stock which have not previously been converted or redeemed, at a price
equal to the Optional Redemption Price (as defined below), provided, that the
Company shall not be entitled to deliver an Optional Redemption Notice to the
Holders if: (i) the number of shares of Common Stock at the time authorized,
unissued and unreserved for all purposes is insufficient to satisfy the
Company's conversion obligations of all shares of Preferred Stock then
outstanding, or (ii) the Underlying Shares then outstanding are not registered
for resale pursuant to an effective Underlying Securities Registration Statement
and may not be sold without volume restrictions pursuant to Rule 144 promulgated
under the Securities Act, as determined by counsel to the Company pursuant to a
written opinion letter, addressed to the Company's transfer agent in the form
and substance acceptable to the Holders and such transfer agent, or (iii) the
Common Stock is not then listed for trading on the NASDAQ or a Subsequent
Exchange. The entire Optional Redemption Price shall be paid in cash. Holders
may convert (and the Company shall honor such conversions in accordance with the
terms hereof) any shares of Preferred Stock, including shares subject to an
Optional Redemption Notice, during the period from the date thereof through the
20th Trading Day after the receipt of an Optional Redemption Notice.

        (b) If any portion of the Optional Redemption Price shall not be paid by
the Company by the 20th Trading Day after the delivery of an Optional Redemption
Notice, interest shall accrue thereon at the rate of 15% per annum until the
Optional Redemption Price plus all such interest is paid in full. In addition,
if any portion of the Optional Redemption Price remains unpaid after the date
due, the Holder of the Preferred Stock subject to such redemption may elect, by
written notice to the Company given at any time thereafter, to either (i) demand
conversion of all or any portion of the shares of Preferred Stock for which such
Optional Redemption Price, plus interest thereof, has not been paid in full (the
"Unpaid Redemption Shares"), in which event the Per Share Market Value for such
shares shall be the lower of the Per Share Market Value calculated on the date
the Optional Redemption Price was originally due and the Per Share Market Value
as of the Holder's


                                      -13-
<PAGE>   37

written demand for conversion, or (ii) invalidate ab initio such redemption,
notwithstanding anything herein contained to the contrary. If the Holder elects
option (i) above, the Company shall within three (3) Trading Days of its receipt
of such election deliver to the Holder the shares of Common Stock issuable upon
conversion of the Unpaid Redemption Shares subject to such Holder conversion
demand and otherwise perform its obligations hereunder with respect thereto; or,
if the Holder elects option (ii) above, the Company shall promptly, and in any
event not later than three (3) Trading Days from receipt of Holder's notice of
such election, return to the Holder all of the Unpaid Redemption Shares.

        (c) The "Optional Redemption Price" shall equal the sum of (i) the
product of (A) the number of shares of Preferred Stock to be redeemed and (B)
$11,000, and (ii) all other amounts, costs, expenses and liquidated damages due
in respect of such shares of Preferred Stock.

        Section 7. Redemption Upon Triggering Events.

        (a) Upon the occurrence of a Triggering Event, each Holder shall (in
addition to all other rights it may have hereunder or under applicable law), has
the right, exercisable at the sole option of such Holder, to require the Company
to redeem all or a portion of the Preferred Stock then held by such Holder for a
redemption price, in cash, equal to the sum of (i) the Mandatory Redemption
Amount plus (ii) the product of (A) the number of Underlying Shares issued in
respect of conversions or as payment of dividends hereunder and then held by the
Holder and (B) the Per Share Market Value on the date such redemption is
demanded or the date the redemption price hereunder is paid in full, whichever
is greater. If the Company fails to pay the redemption price hereunder in full
pursuant to this Section within seven (7) days after the date of a demand
therefor, the Company will pay interest thereon at a rate of 15% per annum,
accruing daily from such seventh day until the redemption price, plus all such
interest thereon, is paid in full. For purposes of this Section, a share of
Preferred Stock is outstanding until such date as the Holder shall have received
Underlying Shares upon a conversion (or attempted conversion) thereof.

            A "Triggering Event" means any one or more of the following events
(whatever the reason and whether it shall be voluntary or involuntary or
effected by operation of law or pursuant to any judgement, decree or order of
any court, or any order, rule or regulation of any administrative or
governmental body):

                     (i) the failure of an Underlying Securities Registration 
Statement to be declared effective by the Commission on or prior to March 31,
1999;

                     (ii) if, during the Effectiveness Period, the effectiveness
of the Underlying Securities Registration Statement lapses for any reason, or
the Holder shall not be permitted to resell Registrable Securities under the
Underlying Securities Registration Statement;

                     (iii) the failure of the Common Stock to be listed for
trading on the NASDAQ or on a Subsequent Market or the suspension of the Common
Stock from trading on the NASDAQ or on a Subsequent Market, in either case, for
more than three (3) consecutive days;


                                      -14-
<PAGE>   38

                    (iv) (A) the Company shall fail for any reason to deliver
certificates representing Underlying Shares issuable upon a conversion hereunder
that comply with the provisions hereof (x) prior to the 10th day after the
Conversion Date after receipt of notice from a Holder given on or prior to the
6th day after the Conversion Date or (y) prior to the 3rd day after receipt of
notice from a Holder given on or after the 7th day after the Conversion Date or
(B) the Company shall provide notice to any Holder, including by way of public
announcement, at any time, of its intention not to comply with requests for
conversion of any Preferred Stock in accordance with the terms hereof;

                    (v) the Company shall be a party to any Change of Control
Transaction, shall agree to sell (in one or a series of related transactions)
all or substantially all of its assets (whether or not such sale would
constitute a Change of Control Transaction) or shall redeem more than a de
minimis number of shares of Common Stock or other Junior Securities (other than
redemptions of Underlying Shares);

                    (vi) an Event shall not have been cured to the satisfaction
of the Holders prior to the expiration of thirty (30) days from the Event Date
relating thereto;

                    (vii) the Company shall fail for any reason to pay in cash
the amount due pursuant to a Buy-In within seven (7) days after notice thereof
is delivered hereunder;

                    (viii) the Company shall fail to have available a sufficient
number of authorized and unreserved shares of Common Stock to issue to such
Holder upon a conversion hereunder; or

                    (ix) the Company convenes a meeting of shareholders pursuant
to Section 5(a)(ii)(B), but fails to obtain Shareholder Approval at such
meeting.

Stock, the number of shares of Common Stock issuable as dividends thereon and

Registration Statement hereunder.

Registrable Securities for an offering to be made on a continuous basis pursuant
to Rule 415. The Registration Statement shall be on Form S-3 (except if
otherwise directed by the Holders of a majority in interest of the applicable
Registrable Securities in accordance herewith or if the Company is not then
eligible to register for resale the Registrable Securities on Form S-3, in which
case such registration shall be on another appropriate form in accordance
herewith). The Registration Statement shall state, to the extent permitted by
Rule 416 under the Securities Act, that it also covers such indeterminate number
of shares of Common Stock as may be required to effect conversion of the
Preferred Stock (and payment of dividends thereon) and exercise of the Warrants
to prevent dilution resulting from stock splits, stock dividends or similar
events, or by reason of changes in the Conversion Price in accordance with the
terms of the Certificate of Designation (as defined in the Purchase Agreement)
or by reason of changes in the Exercise Price (as defined in the Warrants) in
accordance with the terms of the Warrants. The Company shall use its best
efforts to cause the Registration Statement to be declared effective under the
Securities Act as promptly as possible after the filing thereof, but in any
event prior to the Effectiveness Date, and shall use its best efforts to keep
such Registration Statement continuously effective under the Securities Act
until the date which is three years after the date that such Registration
Statement is declared effective by the Commission or such earlier date when all
Registrable Securities covered by such Registration Statement have been sold or
may be sold without volume restrictions pursuant to Rule 144(k) as determined by
the counsel to the Company pursuant to a written opinion letter to such effect,
addressed and acceptable to the Company's transfer agent (the "Effectiveness
Period"), provided, however, that the Company shall not be deemed to have used
its best efforts to keep the Registration Statement effective during the
Effectiveness Period if it voluntarily takes any action that would result in the
Holders not being able to sell the Registrable Securities covered by such
Registration Statement during the Effectiveness Period, unless such action is
required under applicable law or the Company has filed a post-effective
amendment to the Registration Statement and the Commission has not declared it
effective.

                  (b) If the Holders of a majority of the Registrable Securities
so elect, an offering of Registrable Securities pursuant to the Registration
Statement may be effected in the form of an Underwritten Offering. In such
event, and, if the managing underwriters advise the Company and such Holders in
writing that in their opinion the amount of Registrable Securities proposed to
be sold in such Underwritten Offering exceeds the amount of Registrable
Securities which can be sold in such Underwritten Offering, there shall be
included in such Underwritten Offering the amount of such Registrable Securities
which in the opinion of such managing underwriters can be sold, and such amount
shall be allocated pro rata among the Holders proposing to sell Registrable
Securities in such Underwritten Offering.

Underwritten Offering, the investment banker in interest that will administer
the offering will be selected by the Holders of a majority of the Registrable
Securities included in such offering upon consultation with the Company. No
Holder may participate in any Underwritten Offering hereunder unless such Holder
(i) agrees to sell its Registrable Securities on the basis provided in any
underwriting agreements approved by the Persons entitled hereunder to approve
such arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents required
under the terms of such arrangements.

                  In connection with the Company's registration obligations
hereunder, the Company shall:

connection with an Underwritten Offering hereunder, such other form agreed to by
the Company and by the Holders of Registrable Securities) in accordance with the
method or methods of distribution thereof as specified by the Holders (except if
otherwise directed by the Holders), and cause the Registration Statement to

Holders, their Special Counsel and any managing underwriters, copies of all such
documents proposed to be filed, which documents (other than those incorporated
or deemed to be incorporated by reference) will be subject to the review of such
Holders, their Special Counsel and such managing underwriters, and (ii) cause
its officers and directors, counsel and independent certified public accountants
to respond to such inquiries as shall be necessary, in the reasonable opinion of
respective counsel to such Holders and such underwriters, to conduct a
reasonable investigation within the meaning of the Securities Act. The Company
shall not file the Registration Statement or any such Prospectus or any
amendments or supplements thereto to which the Holders of a majority of the
Registrable Securities, their Special Counsel, or any managing underwriters,
shall reasonably object on a timely basis.

                  (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as reasonably possible, but in any
event within ten (10) Business Days, to any comments received from the
Commission with respect to the Registration Statement or any amendment thereto
and

                                       -5-

<PAGE>   6



as promptly as reasonably possible provide the Holders true and complete copies
of all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

                  (c) Notify the Holders of Registrable Securities to be sold,
their Special Counsel and any managing underwriters as promptly as reasonably
possible (and, in the case of (i)(A) below, not less than five (5) days prior to
such filing) and (if requested by any such Person) confirm such notice in
writing no later than one (1) Business Day following the day (i)(A) when a
Prospectus or any Prospectus supplement or post-effective amendment to the
Registration Statement is proposed to be filed; (B) when the Commission notifies
the Company whether there will be a "review" of such Registration Statement and
whenever the Commission comments in writing on such Registration Statement (the
Company shall provide true and complete copies thereof and all written responses
thereto to each of the Holders); and (C) with respect to the Registration
Statement or any post-effective amendment, when the same has become effective;
(ii) of any request by the Commission or any other Federal or state governmental
authority for amendments or supplements to the Registration Statement or
Prospectus or for additional information; (iii) of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement covering any or all of the Registrable Securities or the initiation of
any Proceedings for that purpose; (iv) if at any time any of the representations
and warranties of the Company contained in any agreement (including any
underwriting agreement) contemplated hereby ceases to be true and correct in all
material respects; (v) of the receipt by the Company of any notification with
respect to the suspension of the qualification or exemption from qualification
of any of the Registrable Securities for sale in any jurisdiction, or the
initiation or threatening of any Proceeding for such purpose; and (vi) of the
occurrence of any event that makes any statement made in the Registration
Statement or Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

                  (d) Use its best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of (i) any order suspending the effectiveness of
the Registration Statement, or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.

                  (e) If requested by any managing underwriter or the Holders of
a majority in interest of the Registrable Securities to be sold in connection
with an Underwritten Offering, (i) promptly incorporate in a Prospectus
supplement or post-effective amendment to the Registration Statement such
information as such managing underwriters and such Holders reasonably agree
should be included therein, and (ii) make all required filings of such
Prospectus supplement or


                                                   Registration Rights Agreement

such post-effective amendment as soon as practicable after the Company has
received notification of the matters to be incorporated in such Prospectus
supplement or post-effective amendment; provided, however, that the Company
shall not be required to take any action pursuant to this Section 3(e) that
would, in the opinion of counsel for the Company, violate applicable law or be
materially detrimental to the business prospects of the Company.

                  (f) Furnish to each Holder, their Special Counsel and any
managing underwriters, without charge, at least one conformed copy of each
Registration Statement and each amendment thereto, including financial
statements and schedules, all documents incorporated or deemed to be
incorporated therein by reference, and all exhibits to the extent requested by
such Person (including those previously furnished or incorporated by reference)
promptly after the filing of such documents with the Commission.

                  (g) Promptly deliver to each Holder, their Special Counsel,
and any underwriters, without charge, as many copies of the Prospectus or
Prospectuses (including each form of prospectus) and each amendment or
supplement thereto as such Persons may reasonably request; and the Company
hereby consents to the use of such Prospectus and each amendment or supplement
thereto by each of the selling Holders and any underwriters in connection with
the offering and sale of the Registrable Securities covered by such Prospectus
and any amendment or supplement thereto.

                  (h) Prior to any public offering of Registrable Securities,
use its best efforts to register or qualify or cooperate with the selling
Holders, any underwriters and their Special Counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as
any Holder or underwriter requests in writing, to keep each such registration or
qualification (or exemption therefrom) effective during the Effectiveness Period
and to do any and all other acts or things necessary or advisable to enable the
disposition in such jurisdictions of the Registrable Securities covered by a
Registration Statement; provided, however, that the Company shall not be
required to qualify generally to do business in any jurisdiction where it is not
then so qualified or to take any action that would subject it to general service
of process in any such jurisdiction where it is not then so subject or subject
the Company to any material tax in any such jurisdiction where it is not then so
subject.

                  (i) Cooperate with the Holders and any managing underwriters
to facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be delivered to a transferee pursuant to a
Registration Statement, which certificates shall be free, to the extent
permitted by applicable law, of all restrictive legends, and to enable such
Registrable Securities to be in such denominations and registered in such names
as any such managing underwriters or Holders may request at least two Business
Days prior to any sale of Registrable Securities.

                  (j) Upon the occurrence of any event contemplated by Section
3(c)(vi), as promptly as reasonably possible, prepare a supplement or amendment,
including a post-effective amendment, to the Registration Statement or a
supplement to the related Prospectus or any document incorporated or deemed to
be incorporated therein by reference, and file any other

required document so that, as thereafter delivered, neither the Registration
Statement nor such Prospectus will contain 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, in light of the circumstances under which they
were made, not misleading.

                  (k) Use its best efforts to cause all Registrable Securities
relating to such Registration Statement to be listed on the Nasdaq SmallCap
Market (the "NASDAQ") and any other securities exchange, quotation system,
market or over-the-counter bulletin board, if any, on which similar securities
issued by the Company are then listed as and when required pursuant to the
Purchase Agreement.

                  (l) Enter into such agreements (including an underwriting
agreement in form, scope and substance as is customary in Underwritten
Offerings) and take all such other actions in connection therewith (including
those reasonably requested by any managing underwriters and the Holders of a
majority of the Registrable Securities being sold) in order to expedite or
facilitate the disposition of such Registrable Securities, and whether or not an
underwriting agreement is entered into, (i) make such representations and
warranties to such Holders and such underwriters as are customarily made by
issuers to underwriters in underwritten public offerings, and confirm the same
if and when requested; (ii) in the case of an Underwritten Offering obtain and
deliver copies thereof to each Holder and the managing underwriters, if any, of
opinions of counsel to the Company and updates thereof addressed to each Holder
and each such underwriter, in form, scope and substance reasonably satisfactory
to any such managing underwriters and Special Counsel to the selling Holders
covering the matters customarily covered in opinions requested in Underwritten
Offerings and such other matters as may be reasonably requested by such Special
Counsel and underwriters; (iii) immediately prior to the effectiveness of the
Registration Statement, and, in the case of an Underwritten Offering, at the
time of delivery of any Registrable Securities sold pursuant thereto, use its
best reasonable efforts to obtain and deliver copies to the Holders and the
managing underwriters, if any, of "cold comfort" letters and updates thereof
from the independent certified public accountants of the Company (and, if
necessary, any other independent certified public accountants of any subsidiary
of the Company or of any business acquired by the Company for which financial
statements and financial data is, or is required to be, included in the
Registration Statement), addressed to the Company in form and substance as are
customary in connection with Underwritten Offerings; (iv) if an underwriting
agreement is entered into, the same shall contain indemnification provisions and
procedures no less favorable to the selling Holders and the underwriters, if
any, than those set forth in Section 5 (or such other provisions and procedures
acceptable to the managing underwriters, if any, and holders of a majority of
Registrable Securities participating in such Underwritten Offering); and (v)
deliver such documents and certificates as may be reasonably requested by the
Holders of a majority of the Registrable Securities being sold, their Special
Counsel and any managing underwriters to evidence the continued validity of the
representations and warranties made pursuant to clause 3(l)(i) above and to
evidence compliance with any customary conditions contained in the underwriting
agreement or other agreement entered into by the Company.

                  (m) Make available for inspection by the selling Holders, any
representative of such Holders, any underwriter participating in any disposition
of Registrable Securities, and any

attorney or accountant retained by such selling Holders or underwriters, at the
offices where normally kept, during reasonable business hours, all financial and
other records, pertinent corporate documents and properties of the Company and
its subsidiaries, and cause the officers, directors, agents and employees of the
Company and its subsidiaries to supply all information in each case reasonably
requested by any such Holder, representative, underwriter, attorney or
accountant in connection with the Registration Statement; provided, however,
that any information that is determined in good faith by the Company in writing
to be of a confidential nature at the time of delivery of such information shall
be kept confidential by such Persons, unless (i) disclosure of such information
is required by court or administrative order or is necessary to respond to
inquiries of regulatory authorities; (ii) disclosure of such information, in the
opinion of counsel to such Person, is required by law; (iii) such information
becomes generally available to the public other than as a result of a disclosure
or failure to safeguard by such Person; or (iv) such information becomes
available to such Person from a source other than the Company and such source is
not known by such Person to be bound by a confidentiality agreement with the
Company.

                  (n) Comply with all applicable rules and regulations of the
Commission.

                  (o) The Company may require each selling Holder to furnish to
the Company such information regarding the distribution of such Registrable
Securities and the beneficial ownership of Common Stock held by such Holder as
is required by law to be disclosed in the Registration Statement, and the
Company may exclude from such registration the Registrable Securities of any
such Holder who unreasonably fails to furnish such information within a
reasonable time after receiving such request.

                  If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar Federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

                  Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to
the Registration Statement.

                  Each Holder agrees by its acquisition of such Registrable
Securities that, upon receipt of a notice from the Company of the occurrence of
any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv),
3(c)(v) or 3(c)(vi), such Holder will forthwith discontinue disposition of such
Registrable Securities under the Registration Statement until such Holder's
receipt of the copies of the supplemented Prospectus and/or amended Registration
Statement

contemplated by Section 3(j), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

                  4.       Registration Expenses

                  (a) All fees and expenses incident to the performance of or
compliance with this Agreement by the Company, except as and to the extent
specified in Section 4(b), shall be borne by the Company whether or not pursuant
to an Underwritten Offering and whether or not the Registration Statement is
filed or becomes effective and whether or not any Registrable Securities are
sold pursuant to the Registration Statement. The fees and expenses referred to
in the foregoing sentence shall include, without limitation, (i) all
registration and filing fees (including, without limitation, fees and expenses
(A) with respect to filings required to be made with the NASDAQ or each other
securities exchange or market on which Registrable Securities are required
hereunder to be listed and (B) in compliance with state securities or Blue Sky
laws (including, without limitation, fees and disbursements of counsel for the
Holders in connection with Blue Sky qualifications or exemptions of the
Registrable Securities and determination of the eligibility of the Registrable
Securities for investment under the laws of such jurisdictions as the managing
underwriters, if any, or the Holders of a majority of Registrable Securities may
designate)), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities and of printing prospectuses if
the printing of prospectuses is requested by the managing underwriters, if any,
or by the holders of a majority of the Registrable Securities included in the
Registration Statement), (iii) messenger, telephone and delivery expenses, (iv)
fees and disbursements of counsel for the Company and Special Counsel for the
Holders, (v) Securities Act liability insurance, if the Company so desires such
insurance, and (vi) fees and expenses of all other Persons retained by the
Company in connection with the consummation of the transactions contemplated by
this Agreement. In addition, the Company shall be responsible for all of its
internal expenses incurred in connection with the consummation of the
transactions contemplated by this Agreement (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expense of any annual audit, the fees and expenses
incurred in connection with the listing of the Registrable Securities on any
securities exchange as required hereunder.

                  (b) If the Holders require an Underwritten Offering pursuant
to the terms hereof, the Company shall be responsible for all costs, fees and
expenses in connection therewith, except for the fees and disbursements of the
Underwriters (including any underwriting commissions and discounts) and their
legal counsel and accountants. By way of illustration which is not intended to
diminish from the provisions of Section 4(a), the Holders shall not be
responsible for, and the Company shall be required to pay the fees or
disbursements incurred by the Company (including by its legal counsel and
accountants) in connection with, the preparation and filing of a Registration
Statement and related Prospectus for such offering, the maintenance of such
Registration Statement in accordance with the terms hereof, the listing of the
Registrable Securities in accordance with the requirements hereof, and printing
expenses incurred to comply with the requirements hereof.

         5.       Indemnification

                  (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents (including any underwriters
retained by such Holder in connection with the offer and sale of Registrable
Securities), brokers (including brokers who offer and sell Registrable
Securities as principal as a result of a pledge or any failure to perform under
a margin call of Common Stock), investment advisors and employees of each of
them, each Person who controls any such Holder (within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act) and the officers,
directors, agents and employees of each such controlling Person, to the fullest
extent permitted by applicable law, from and against any and all losses, claims,
damages, liabilities, costs (including, without limitation, costs of preparation
and attorneys' fees) and expenses (collectively, "Losses"), as incurred, arising
out of or relating to any untrue or alleged untrue statement of a material fact
contained in the Registration Statement, any Prospectus or any form of
prospectus or in any amendment or supplement thereto or in any preliminary
prospectus, or arising out of or relating to any omission or alleged omission of
a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in light of the circumstances under which they were made)
not misleading, except to the extent, but only to the extent, that such untrue
statements or omissions are based solely upon information regarding such Holder
furnished in writing to the Company by such Holder expressly for use therein,
which information was reasonably relied on by the Company for use therein or to
the extent that such information relates to such Holder or such Holder's
proposed method of distribution of Registrable Securities and was reviewed and
expressly approved in writing by such Holder expressly for use in the
Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto. The Company shall notify the Holders promptly
of the institution, threat or assertion of any Proceeding of which the Company
is aware in connection with the transactions contemplated by this Agreement.

                  (b) Indemnification by Holders. Each Holder shall, severally
and not jointly, indemnify and hold harmless the Company, its directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons, to
the fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising solely out of or based solely upon any untrue
statement of a material fact contained in the Registration Statement, any
Prospectus, or any form of prospectus, or in any amendment or supplement
thereto, or arising solely out of or based solely upon any omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in the Registration
Statement or such Prospectus and that such information was reasonably relied
upon by the Company for use in the Registration Statement, such Prospectus or
such form of prospectus or to the extent that such information relates to such
Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such




                                                   Registration Rights Agreement


                                      -11-

<PAGE>   12



form of Prospectus, or in any amendment or supplement thereto. In no event shall
the liability of any selling Holder hereunder be greater in amount than the
dollar amount of the net proceeds received by such Holder upon the sale of the
Registrable Securities giving rise to such indemnification obligation.

                  (c) Conduct of Indemnification Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party shall promptly notify the
Person from whom indemnity is sought (the "Indemnifying Party") in writing, and
the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

                  An Indemnified Party shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such
Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; or (2) the Indemnifying Party shall have
failed promptly to assume the defense of such Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named parties to any such Proceeding (including any impleaded parties)
include both such Indemnified Party and the Indemnifying Party, and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified Party
and the Indemnifying Party (in which case, if such Indemnified Party notifies
the Indemnifying Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

                  All fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within 10 Business Days of written notice thereof to the Indemnifying
Party (regard less of whether it is ultimately determined that an Indemnified
Party is not entitled to indemnification hereunder; provided, that the
Indemnifying Party may require such Indemnified Party to undertake to reimburse
all such fees and expenses to the extent it is finally judicially determined
that such Indemnified Party is not entitled to indemnification hereunder).

<PAGE>   13



                  (d) Contribution. If a claim for indemnification under Section
5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public policy
or otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party and Indemnified Party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information supplied by, such Indemnifying Party or Indemnified Party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action, statement or omission. The amount paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or other
reasonable fees or expenses incurred by such party in connection with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to
such party in accordance with its terms.

                  The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 5(d) were determined by pro
rata allocation or by any other method of allocation that does not take into
account the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 5(d), no Holder shall
be required to contribute, in the aggregate, any amount in excess of the amount
by which the proceeds actually received by such Holder from the sale of the
Registrable Securities subject to the Proceeding exceeds the amount of any
damages that such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No Person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any Person who was
not guilty of such fraudulent misrepresentation.

                  The indemnity and contribution agreements contained in this
Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties.

         6.       Miscellaneous

                  (a) Remedies. In the event of a breach by the Company or by a
Holder, of any of their obligations under this Agreement, each Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate
compensation for any losses incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the
defense that a remedy at law would be adequate.

<PAGE>   14



                  (b) No Inconsistent Agreements. Neither the Company nor any of
its subsidiaries has, as of the date hereof, nor shall the Company or any of its
subsidiaries, on or after the date of this Agreement, enter into any agreement
with respect to its securities that is inconsistent with the rights granted to
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
Except as and to the extent specified in Schedule 6(b) hereto, neither the
Company nor any of its subsidiaries has previously entered into any agreement
granting any registration rights with respect to any of its securities to any
Person. Without limiting the generality of the foregoing, without the written
consent of the Holders of a majority of the then outstanding Registrable
Securities, the Company shall not grant to any Person the right to request the
Company to register any securities of the Company under the Securities Act
unless the rights so granted are subject in all respects to the prior rights in
full of the Holders set forth herein, and are not otherwise in conflict or
inconsistent with the provisions of this Agreement.

                  (c) No Piggyback on Registrations. Except as and to the extent
specified in Schedule 6(b) hereto, neither the Company nor any of its security
holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in the Registration Statement other than the
Registrable Securities, and the Company shall not after the date hereof enter
into any agreement providing any such right to any of its security holders.

                  (d) Piggy-Back Registrations. If at any time when there is not
an effective Registration Statement covering all of the Registrable Securities
and the Underlying Shares, the Company shall determine to prepare and file with
the Commission a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or their then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, then the Company shall send to each holder of Registrable
Securities written notice of such determination and, if within twenty (20) days
after receipt of such notice, any such holder shall so request in writing, the
Company shall include in such registration statement all or any part of such
Registrable Securities such holder requests to be registered; provided, however,
that the Company shall not be required to register any Registrable Securities
pursuant to this Section 7(d) that are eligible for sale pursuant to Rule 144(k)
of the Commission.

                  (e) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of at least two-thirds of the then outstanding Registrable
Securities; provided, however, that, for the purposes of this sentence,
Registrable Securities that are owned, directly or indirectly, by the Company,
or an Affiliate of the Company are not deemed outstanding. Notwithstanding the
foregoing, a waiver or consent to depart from the provisions hereof with respect
to a matter that relates exclusively to the rights of Holders and that does not
directly or indirectly affect the rights of other Holders may be given by
Holders of at least a majority of the Registrable Securities to which such
waiver or consent relates; provided, however, that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance with
the provisions of the immediately preceding sentence.

Tanisys Technology, Inc.
12201 Technology Boulevard, Suite 125
Austin, Texas 78727


Dear Sirs:

     As counsel to Tanisys Technology, Inc., a Wyoming corporation (the
"Company"), we are familiar with the Registration Statement on Form S-3 (the
"Registration Statement") to be filed with the Securities and Exchange
Commission on or about August 14, 1998, under the Securities Act of 1933, as
amended, relating to an aggregate of 5,353,374 shares of common stock, no par
value ("Common Stock"), of the Company to be sold by certain selling
stockholders listed in the Registration Statement (the "Selling Stockholders").
The Shares will be issued pursuant to the proper and valid (i) conversion of
Series A Convertible Preferred Stock, $1.00 par value per share ("Series A
Stock") or (ii) exercise of certain warrants (the "Warrants") held by the
Selling Stockholders, each as described in the Registration Statement.

     In connection therewith, we have examined such corporate records,
documents and such questions of law as we have considered necessary or
appropriate for the purposes of this opinion and, upon the basis of such
examination, advise you that in our opinion the shares of Common Stock to be
sold by the Selling Stockholders have been duly and validly authorized, and
when issued in accordance with the terms of the (i) Articles of Continuance of
the Company, as amended, or (ii) Warrants, will be validly issued, fully paid
and nonassessable.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and the reference to our firm under the heading "Legal Matters" in
the Prospectus which is contained in the Registration Statement.

                                             Very truly yours,




                                             /s/ Fulbright & Jaworski L.L.P.

                         REPRESENTATIONS AND WARRANTIES

         2.1 Representations, Warranties and Agreements of the Company. The
Company hereby makes the following representations and warranties to the
Purchaser:

             (a) Organization and Qualification. The Company is a corporation,
duly incorporated, validly existing and in good standing under the laws of the
State of Wyoming, with the requisite corporate power and authority to own and
use its properties and assets and to carry on its business as currently
conducted. The Company has no subsidiaries other than as set forth in Schedule
2.1(a) (collectively the "Subsidiaries"). Each of the Subsidiaries is an entity,
duly incorporated or otherwise organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or organization (as
applicable), with the full power and authority to own and use its properties and
assets and to carry on its business as currently conducted. Each of the Company
and the Subsidiaries is duly qualified to do business and is in good standing as
a foreign corporation in each jurisdiction in which the nature of the business
conducted or property owned by it makes such qualification necessary, except
where the failure to be so qualified or in good standing, as the case may be,
could not, individually or in the aggregate, (x) adversely affect the legality,
validity or enforceability of the Securities (as defined below) or any of this
Agreement, the Articles of Amendment, the Registration Rights Agreement or the
Warrant (collectively, the "Transaction Documents"), (y) have or result in a
material adverse effect on the results of operations, assets, prospects, or
condition (financial or otherwise) of the Company and the Subsidiaries, taken as
a whole, or (z) adversely impair the Company's ability to perform fully on a
timely basis its obligations under any of the Transaction Documents (any of (x),
(y) or (z), a "Material Adverse Effect").

             (b) Authorization; Enforcement. The Company has the requisite
corporate power and authority to enter into and to consummate the transactions
contemplated by each of the Transaction Documents, and otherwise to carry out
its obligations thereunder. The execution and delivery of each of the
Transaction Documents


                                      -2-                  Convertible Preferred
                                                        Stock Purchase Agreement
<PAGE>   4
has been duly executed by the Company and, when delivered (or filed, as the case
may be) in accordance with the terms hereof, will constitute the valid and
binding obligation of the Company enforceable against the Company in accordance
with its terms. Neither the Company nor any Subsidiary is in violation of any of
the provisions of its respective certificate of incorporation, by-laws or other
charter documents.

             (c) Capitalization. The number of authorized, issued and
outstanding capital stock of the Company is set forth in Schedule 2.1(c). No
shares of Common Stock are entitled to preemptive or similar rights, nor is any
holder of the Common Stock entitled to preemptive or similar rights arising out
of any agreement or understanding with the Company by virtue of any of the
Transaction Documents. Except as disclosed in Schedule 2.1(c), there are no
outstanding options, warrants, script rights to subscribe to, calls or
commitments of any character whatsoever relating to, or, except as a result of
the purchase and sale of the Shares and the Warrant, securities, rights or
obligations convertible into or exchangeable for, or giving any Person any right
to subscribe for or acquire any shares of Common Stock, or contracts,
commitments, understandings, or arrangements by which the Company or any
Subsidiary is or may become bound to issue additional shares of Common Stock, or
securities or rights convertible or exchangeable into shares of Common Stock. To
the knowledge of the Company, except as specifically disclosed in the SEC
Documents (as defined below) or Schedule 2.1(c), no Person or group of related
Persons beneficially owns (as determined pursuant to Rule 13d-3 promulgated
under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) or
has the right to acquire by agreement with or by obligation binding upon the
Company beneficial ownership of in excess of 5% of the Common Stock. A "Person"
means an individual or corporation, partnership, trust, incorporated or
unincorporated association, joint venture, limited liability company, joint
stock company, government (or an agency or subdivision thereof) or other entity
of any kind.

             (d) Issuance of the Shares and the Warrant. The Shares and the
Warrant are duly authorized, and, when issued and paid for in accordance with
the terms hereof, shall have been validly issued, fully paid and nonassessable,
free and clear of all liens, encumbrances and rights of first refusal of any
kind (collectively, "Liens"). The Company has on the date hereof and will, at
all times while the Shares and the Warrant are outstanding, maintain an adequate
reserve of duly authorized shares of Common Stock, reserved for issuance to the
holders of the Shares, to enable it to perform its conversion, exercise and
other obligations under this Agreement, the Articles of Amendment and the
Warrant. Such number of reserved and available shares of Common Stock is not
less than the sum of (i) 200% of the number of shares of Common Stock which
would be issuable upon conversion in full of the Shares, assuming such
conversion occurred on the Original Issue Date or the Filing Date (as defined in
the Registration Rights Agreement), whichever yields a lower Conversion Price,
(ii) the number of shares of Common Stock issuable upon exercise of the Warrant,
and (iii) the number of shares Common Stock which would be issuable upon payment
of dividends on the Shares, assuming each Share is outstanding for three years
and all dividends are paid in shares of Common Stock (such number of shares, the
"Initial Minimum"). All such authorized shares of Common Stock shall be duly
reserved for issuance to the holders of such Shares and Warrant. The shares of
Common Stock issuable upon conversion of the Shares, as payment of dividends
thereon and upon exercise of the Warrant are collectively referred to herein as
the "Underlying Shares." The Shares, the Warrant and the Underlying Shares are,
collectively, the "Securities." When issued in accordance with the 


                                      -3-                  Convertible Preferred

<PAGE>   5

Articles of Amendment and the Warrant, in accordance with their respective
terms, the Underlying Shares shall have been duly authorized, validly issued,
fully paid and nonassessable, free and clear of all Liens.

             (e) No Conflicts. The execution, delivery and performance of the
Transaction Documents by the Company and the consummation by the Company of the
transactions contemplated thereby do not and will not (i) conflict with or
violate any provision of its certificate of incorporation, bylaws or other
charter documents (each as amended through the date hereof), or (ii) subject to
obtaining the Required Approvals (as defined below), conflict with, or
constitute a default (or an event which with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation (with or without notice, lapse of time
or both) of, any agreement, credit facility, indenture or instrument (evidencing
a Company debt or otherwise) to which the Company or any Subsidiary is a party
or by which any property or asset of the Company or any Subsidiary is bound or
affected, or (iii) result in a violation of any law, rule, regulation, order,
judgment, injunction, decree or other restriction of any court or governmental
authority to which the Company is subject (including Federal and state
securities laws and regulations), or by which any property or asset of the
Company is bound or affected, except in the case of each of clauses (ii) and
(iii), as could not, individually or in the aggregate, have or result in a
Material Adverse Effect. The business of the Company is not being conducted in
violation of any law, ordinance or regulation of any governmental authority,
except for violations which, individually or in the aggregate, could not have or
result in a Material Adverse Effect.

             (f) Consents and Approvals. Neither the Company nor any Subsidiary
is required to obtain any consent, waiver, authorization or order of, give any
notice to, or make any filing or registration with, any court or other Federal,
state, local or other governmental authority or other Person in connection with
the execution, delivery and performance by the Company of the Transaction
Documents, other than (i) the filing of the Articles of Amendment with the
Secretary of State of Wyoming, (ii) the filings required pursuant to Section
3.12, (iii) the filing of a registration statement meeting the requirements set
forth in the Registration Rights Agreement (an "Underlying Securities
Registration Statement") with the Securities and Exchange Commission (the
"Commission") meeting the requirements set forth in the Registration Rights
Agreement and covering the resale of the Underlying Shares by the Purchaser,
(iv) the application(s) to the Nasdaq SmallCap Market (the "NASDAQ") for the
listing of the Underlying Shares with the NASDAQ (and with any other national
securities exchange or market on which the Common Stock is then listed), (v)
applicable Blue Sky filings and, and (vi) in all other cases where the failure
to obtain such consent, waiver, authorization or order, or to give such notice
or make such filing or registration could not have or result in, individually or
in the aggregate, a Material Adverse Effect (the consents, waivers,
authorizations, orders, notices and filings referred to in (i)-(vi) of this
Section are, collectively, the "Required Approvals").

             (g) Litigation; Proceedings. Except as specifically disclosed in
the SEC Documents, there is no action, suit, notice of violation, proceeding or
investigation pending or, to the knowledge of the Company, threatened against or
affecting the Company or any of its Subsidiaries or any of their respective
properties before or by any court, governmental or administrative agency or
regulatory authority (Federal, state, county, local or foreign) which (i)
adversely affects or

challenges the legality, validity or enforceability of any of the Transaction
Documents or the Securities or (ii) could, individually or in the aggregate,
have or result in a Material Adverse Effect.

             (h) No Default or Violation. Neither the Company nor any Subsidiary
(i) is in default under or in violation of (and no event has occurred which has
not been waived which, with notice or lapse of time or both, would result in a
default by the Company or any Subsidiary under), nor has the Company or any

in violation of, any indenture, loan or credit agreement or any other agreement
or instrument to which it is a party or by which it or any of its properties is
bound, (ii) is in violation of any order of any court, arbitrator or
governmental body, or (iii) is in violation of any statute, rule or regulation

behalf has taken any action could subject the offering, issuance or sale of the

and expenses are incurred.

             (m) Solicitation Materials. Neither the Company nor any Person
acting on the Company's behalf has (i) distributed any offering materials in

             (r) Patents and Trademarks. The Company has, or has rights to use,
all patents, patent applications, trademarks, trademark applications, service
marks, trade names, copyrights, licenses and rights (collectively, the
"Intellectual Property Rights") which are necessary or material for use in
connection with its business, and which the failure to so have would have a
Material Adverse Effect. To the best knowledge of the Company, all such
Intellectual Property Rights are enforceable and there is no existing
infringement by another Person of any of the Intellectual Property Rights.

             (s) Registration Rights; Rights of Participation. Except as set
forth on Schedule 6(b) to the Registration Rights Agreement, (i) the Company has
not granted or agreed to grant to any Person any rights (including "piggy-back"

all certificates, authorizations and permits issued by the appropriate Federal,
state or foreign regulatory authorities necessary to conduct their respective
businesses as described in the SEC Documents, except where the failure to
possess such permits could not, individually or in the aggregate, have or result
in a Material Adverse Effect ("Material Permits"), and neither the Company nor
any such Subsidiary has received any notice of proceedings relating to the
revocation or modification of any Material Permit.

             (u) Title. The Company and the Subsidiaries have good and
marketable title in fee simple to all real property and personal property owned
by them which is material to the business of the Company and its Subsidiaries,
in each case free and clear of all Liens, except for liens, claims or
encumbrances as do not materially affect the value of such property and do not
interfere with the use made and proposed to be made of such property by the
Company and its Subsidiaries. Any real property and facilities held under lease
by the Company and its Subsidiaries are held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such property and buildings by the
Company and its Subsidiaries.

             (v) Disclosure. The Company confirms that it has not provided the
Purchaser or its agents or counsel with any information that constitutes or
might constitute material non-public information. The Company understands and
confirms that the Purchaser shall be relying on the foregoing representations in
effecting transactions in securities of the Company. All disclosure provided to
the Purchaser regarding the Company, its business and the transactions
contemplated hereby, including the Schedules to this Agreement, furnished by or
on behalf of the Company are true and correct and do not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading.

         2.2 Representations and Warranties of the Purchaser. The Purchaser
hereby represents and warrants to the Company as follows:

             (a) Organization; Authority. The Purchaser is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation with the requisite corporate power and
authority, to enter into and to consummate the transactions contemplated by the
Transaction Documents and otherwise to carry out its obligations thereunder. The
purchase by the Purchaser of the Securities hereunder has been duly authorized
by all necessary action on the part of the Purchaser. Each of this Agreement and
the Registration Rights Agreement has been duly executed and delivered by the
Purchaser and constitutes the valid and legally binding obligation of the
Purchaser, enforceable against it in accordance with its terms.

             (b) Investment Intent. The Purchaser is acquiring the Securities
for its own account for investment purposes only and not with a view to or for
distributing or reselling such Securities or any part thereof or interest
therein, without prejudice, however, to the Purchaser's right, subject to the
provisions of this Agreement and the Registration Rights Agreement, at all times
to sell or otherwise dispose of all or any part of such Securities pursuant to
an effective registration statement under the Securities Act and in compliance
with applicable state securities laws or under an exemption from such
registration.

             (c) Purchaser Status. At the time the Purchaser was offered the
Shares and the Warrant, it was, and at the date hereof it is, and at each
exercise date under the Warrant, it will be, an "accredited investor" as defined
in Rule 501(a) under the Securities Act.

             (d) Experience of the Purchaser. The Purchaser, either alone or
together with its representatives, has such knowledge, sophistication and
experience in business and financial matters so as to be capable of evaluating
the merits and risks of the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment.

             (e) Ability of the Purchaser to Bear Risk of Investment. The
Purchaser is able to bear the economic risk of an investment in the Securities
and, at the present time, is able to afford a complete loss of such investment.

             (f) Access to Information. The Purchaser acknowledges receipt of
the Disclosure Materials and further acknowledges that it has reviewed the
Disclosure Materials and has been afforded (i) the opportunity to ask such
questions as it has deemed necessary of, and to receive answers from,
representatives of the Company concerning the terms and conditions of the
offering of the Securities and the merits and risks of investing in the
Securities; (ii) access to information about the Company and the Company's
financial condition, results of operations, business, proper ties, management
and prospects sufficient to enable it to evaluate its investment; and (iii) the
opportunity to obtain such additional information which the Company possesses or
can acquire without unreasonable effort or expense that is necessary to make an
informed investment decision with respect to the investment and to verify the
accuracy and completeness of the information contained in the Disclosure
Materials. Neither such inquiries nor any other investigation conducted by or on
behalf of such Purchaser or its representatives or counsel shall modify, amend
or affect such Purchaser's right to rely on the truth, accuracy and completeness
of the Disclosure Materials and the Company's representations and warranties
contained in the Transaction Documents.

<PAGE>   10

             (g) General Solicitation. The Purchaser is not purchasing the
Shares as a result of or subsequent to any advertisement, article, notice or
other communication regarding the Shares published in any newspaper, magazine or
similar media or broadcast over television or radio or presented at any seminar.

             (h) Reliance. The Purchaser understands and acknowledges that (i)
the Securities are being offered and sold to it without registration under the
Securities Act in a private placement that is exempt from the registration
provisions of the Securities Act and (ii) the availability of such exemption,
depends in part on, and the Company will rely upon the accuracy and truthfulness
of, the foregoing representations and the Purchaser hereby consents to such
reliance.

             The Company acknowledges and agrees that the Purchaser makes no
representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in this Section 2.2.


                                   ARTICLE III
                         OTHER AGREEMENTS OF THE PARTIES

         3.1 Transfer Restrictions. (a) Securities may only be disposed of
pursuant to an effective registration statement under the Securities Act, to the
Company or pursuant to an available exemption from or in a transaction not
subject to the registration requirements of the Securities Act. In connection
with any transfer of Securities other than pursuant to an effective registration
statement or to the Company, except as otherwise set forth herein, the Company
may require the transferor thereof to provide to the Company an opinion of
counsel selected by the transferor, the form and substance of which opinion
shall be reasonably satisfactory to the Company, to the effect that such
transfer does not require registration of such transferred securities under the
Securities Act. Notwithstanding the foregoing, the Company hereby consents to
and agrees to register on the books of the Company and with any transfer agent
for the securities of the Company any transfer of Securities by the Purchaser to
an Affiliate of the Purchaser or to a fund under common management with the
Purchaser, and any transfer among any such Affiliates or funds, provided that
transferee certifies to the Company that it is an "accredited investor" as
defined in Rule 501(a) under the Securities Act and that it is acquiring the
Securities solely for investment purposes. Any such transferee shall agree in
writing to be bound by the terms of this Agreement and shall have the rights of
a Purchaser under this Agreement and the Registration Rights Agreement.

             (b) The Purchaser agrees to the imprinting, so long as is required
by this Section 3.1(b), of the following legend on the Securities:

             NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE
       SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN REGISTERED WITH THE
       SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY
       STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE
       SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,
       ACCORDINGLY, MAY NOT BE OFFERED OR SOLD


                                      -9-                  Convertible Preferred
                                                        Stock Purchase Agreement

<PAGE>   11

       EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
       SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A
       TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
       SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS.

             The Company shall issue Underlying Shares free of the legend set
forth above (and free of any other legend) if the conversion of Shares, the
payment of dividends thereon, or exercise of the Warrant or other issuances of
Underlying Shares as contemplated hereby, by the Articles of Amendment or the
Warrant occurs at any time while an Underlying Securities Registration Statement
is effective under the Securities Act or, in the event there is not an effective
Underlying Securities Registration Statement at such time, if in the opinion of
counsel to the Company such legend is not required under applicable requirements
of the Securities Act (including judicial interpretations and pronouncements
issued by the staff of the Commission). The Company shall cause its counsel to
issue the legal opinion included in the Transfer Agent Instructions to the
Company's transfer agent on the day that the Underlying Securities Registration
Statement is declared effective by the Commission. The Company agrees that it
will provide the Purchaser, upon request, with a certificate or certificates
representing Underlying Shares that may have been issued with the restrictive
legend set forth above, free from such legend at such time as such legend is no
longer required hereunder (for example, there is an effective Underlying
Securities Registration Statement). The Company may not make any notation on its
records or give instructions to any transfer agent of the Company which enlarge
the restrictions of transfer set forth in this Section.

         3.2 Acknowledgment of Dilution. The Company acknowledges that the
issuance of the Underlying Shares upon (i) conversion of the Shares and payment
of dividends thereon in accordance with the terms of the Articles of Amendment,
and (ii) exercise of the Warrant in accordance with its terms, may result in
dilution of the outstanding shares of Common Stock, which dilution may be
substantial under certain market conditions. The Company further acknowledges
that its obligation to issue Underlying Shares upon (x) conversion of the Shares
and payment of dividends thereon in accordance with the terms of the Articles of
Amendment, and (y) exercise of the Warrant in accordance with its terms, is
unconditional and absolute, subject to the limitations set forth in the Articles
of Amendment or pursuant to the Warrant, regardless of the effect of any such
dilution.

         3.3 Furnishing of Information. So long as the Purchaser owns
Securities, the Company covenants to timely file (or obtain extensions in
respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Section
13(a) or 15(d) of the Exchange Act. So long as the Purchaser owns Securities, if
the Company is not required to file reports pursuant to such sections, it will
prepare and furnish to the Purchaser and make publicly available in accordance
with Rule 144(c) promulgated under the Securities Act annual and quarterly
financial statements, together with a discussion and analysis of such financial
statements in form and substance substantially similar to those that would
otherwise be required to be included in reports required by Section 13(a) or
15(d) of the Exchange Act, as well as any other information required thereby, in
the time period that such filings would have been required to have been made
under the Exchange Act. The Company further covenants that it will take such
further action as any holder of Securities may reasonably request, all to the
extent required from time to time to enable 


                                     -10-                  Convertible Preferred

<PAGE>   12

such Person to sell Underlying Shares without registration under the Securities
Act within the limitation of the exemptions provided by Rule 144 promulgated
under the Securities Act, including the legal opinion referenced above in this
Section. Upon the request of any such Person, the Company shall deliver to such
Person a written certification of a duly authorized officer as to whether it has
complied with such requirements.

         3.4 Blue Sky Laws. In accordance with the Registration Rights
Agreement, the Company shall qualify or exempt the issuance and sale of the
Underlying Shares under the securities or Blue Sky laws of such jurisdictions as
the Purchaser may reasonably request and shall continue such qualification or
exemption at all times until the Purchaser notifies the Company in writing that
it no longer owns Securities; provided, however, that neither the Company nor
its Subsidiaries shall be required in connection therewith to qualify as a
foreign corporation where they are not now so qualified or to take any action
that would subject the Company to general service of process in any such
jurisdiction where it is not then subject.

         3.5 Integration. The Company shall not, and shall use its best efforts
to ensure that, no Affiliate shall, sell, offer for sale or solicit offers to
buy or otherwise negotiate in respect of any security (as defined in Section 2
of the Securities Act) that would be integrated with the offer or sale of the
Securities in a manner that would require the registration under the Securities
Act of the sale of the Securities to the Purchaser.

         3.6 Increase in Authorized Shares. Subject to the operation of any
floor that may then be applicable to the Conversion Price in accordance with the
Articles of Amendment, at such times as the Company would be, if a notice of
conversion or exercise (as the case may be) were to be delivered on such date,
precluded from (a) issuing 200% of the number of Underlying Shares as would then
be issuable upon a conversion in full of the Shares and as payment of any
accrued and unpaid dividends in respect thereof in shares of Common Stock, or
(b) honoring the exercise in full of the Warrant, in either case, due to the
unavailability of a sufficient number of shares of authorized but unissued or
reserved Common Stock, the Board of Directors of the Company shall promptly (and
in any case, within 30 Business Days from such date) prepare and mail to the
stockholders of the Company proxy materials requesting authorization to amend
the Company's Certificate of Incorporation to increase the number of shares of
Common Stock which the Company is authorized to issue to at least such number of
shares as reasonably requested by the Purchaser in order to provide for such
number of authorized and unissued shares of Common Stock to enable the Company
to comply with its conversion, exercise and reservation of shares obligations as
set forth in this Agreement, the Articles of Amendment and the Warrant (the sum
of (x) the number of shares of Common Stock then authorized, (y) the number of
shares of Common Stock then outstanding plus all shares of Common Stock issuable
upon exercise of all outstanding options, warrants and convertible instruments
(other than the Underlying Shares), and (z) subject to the operation of any
floor that may then be applicable to the Conversion Price in accordance with the
Articles of Amendment the sum of (i) 200% of the number of Underlying Shares as
are then issuable upon a conversion in full of all Shares and as payment of
dividends thereon, and (ii) the number of Underlying Shares as are issuable upon
exercise in full of the Warrant, shall be a reasonable number). In connection
therewith, the Board of Directors shall (a) adopt proper resolutions authorizing
such increase, (b) recommend to and otherwise use its best efforts to promptly
and duly obtain stockholder 


                                     -11-                  Convertible Preferred

<PAGE>   13

approval to carry out such resolutions (and hold a special meeting of the
stockholders no later than the 60th day after delivery of the proxy materials
relating to such meeting) and (c) within five (5) Business Days of obtaining
such stockholder authorization, file an appropriate amendment to the Company's
Certificate of Incorporation to evidence such increase.

         3.7 Listing and Reservation of Underlying Shares. (a) The Company shall
(i) not later than the fifth Business Day following the Closing Date hereunder
prepare and file with the NASDAQ (or such other national securities exchange or
market or trading or quotation facility on which the Common Stock is then
listed) an additional shares listing application covering a number of shares of
Common Stock which is at least equal to the number of shares required to be
reserved pursuant to Section 2.1(d), (ii) take all steps necessary to cause such
shares to be approved for listing in the NASDAQ (as well as on any such other
national securities exchange or market or trading or quotation facility on which
the Common Stock is then listed) as soon as possible thereafter, and (iii)
provide to the Purchaser evidence of such listing, and the Company shall
maintain the listing of its Common Stock thereon. If the number of Underlying
Shares as are issuable upon conversion in full of the then outstanding Shares,
as payment of dividends thereon, and upon exercise of the then unexercised
portion of the Warrant exceeds 85% of the number of Underlying Shares previously
listed on account thereof with NASDAQ (and such other required exchanges), the
Company shall take the necessary actions to immediately list a number of
Underlying Shares as equals the sum of (x) 200% of the number of Underlying
Shares then issuable upon conversion of the Shares and as payment of dividends
thereon and (y) the number of Underlying Shares as are then issuable upon
exercise of the Warrant.

             (b) The Company shall maintain a reserve of Common Stock for
issuance upon conversion of the Shares and for payment of dividends thereupon in
shares of Common Stock pursuant to the terms of the Articles of Amendment and
upon exercise of the Warrant in accordance with its terms, in such amount as may
be required to fulfill obligations in full under the Transaction Documents,
which reserve shall include a number of shares of Common Stock equal to no less
than the Initial Minimum.

         3.8 Conversion Procedures. The Transfer Agent Instructions, Conversion
Notice (as defined in Exhibit A) and Notice of Exercise under the Warrant set
forth the totality of the procedures with respect to the conversion of the
Shares and exercise of the Warrant, including the form of legal opinion, if
necessary, that shall be rendered to the Company's transfer agent and such other
information and instructions as may be reasonably necessary to enable the
Purchaser to convert its Shares and exercise the Warrant as contemplated in the
Articles of Amendment and the Warrant (as applicable).

         3.9 Notice of Breaches. (a) Each of the Company and the Purchaser shall
give prompt written notice to the other of any breach by it of any
representation, warranty or other agreement contained in any Transaction
Document, as well as any events or occurrences arising after the date hereof
which would reasonably be likely to cause any representation or warranty or
other agreement of such party, as the case may be, contained therein to be
incorrect or breached as of the Closing Date. However, no disclosure by either
party pursuant to this Section shall be deemed to cure any breach of any
representation, warranty or other agreement contained in any Transaction
Document.

<PAGE>   14

             (b) Notwithstanding the generality of Section 3.9(a), the Company
shall promptly notify the Purchaser of any notice or claim (written or oral)
that it receives from any lender of the Company to the effect that the
consummation of the transactions contemplated by the Transaction Documents
violates or would violate any written agreement or understanding between such
lender and the Company, and the Company shall promptly furnish by facsimile to
the holders of the Securities a copy of any written statement in support of or
relating to such claim or notice.

         3.10 Conversion and Exercise Obligations of the Company. The Company
shall honor conversions of the Shares and exercises of the Warrant and shall
deliver Underlying Shares in accordance with the respective terms, conditions
and time periods set forth in the respective Articles of Amendment and the
Warrant.

         3.11 Right of First Refusal; Subsequent Registrations. (a) Subject to
the provisions of Section 3.11(b), the Company shall not, directly or
indirectly, without the prior written consent of the Purchaser, offer, sell,
grant any option to purchase, or otherwise dispose of (or announce any offer,
sale, grant or any option to purchase or other disposition) any of its or its
Affiliates' equity or equity-equivalent securities in a transaction intended to
be exempt or not subject to registration under the Securities Act (a "Subsequent
Placement") for a period of 360 days after the Closing Date, except (i) the
granting of options or warrants to employees, officers and directors, and the
issuance of shares upon exercise of options granted, under any stock option plan
heretofore or hereinafter duly adopted by the Company, (ii) shares of Common
Stock issued upon exercise of any currently outstanding warrants and upon
conversion of any currently outstanding convertible securities of the Company,
in each case disclosed in Schedule 2.1(c), (iii) Common Stock issued on a
primary basis pursuant to an underwritten public offering, so long as any shares
of Common Stock sold in such underwritten offering are not sold at a price less
than the average of the Per Share Market Values on the five (5) Trading Days
immediately preceding the sale of such Common Stock and (iv) shares of Common
Stock issued upon conversion of Preferred Stock and as payment of dividends
thereon and upon exercise of the Warrant in accordance with the Articles of
Amendment or the Warrant, respectively, unless (A) the Company delivers to the
Purchaser a written notice (the "Subsequent Placement Notice") of its intention
effect such Subsequent Placement, which Subsequent Placement Notice shall
describe in reasonable detail the proposed terms of such Subsequent Placement,
the amount of proceeds intended to be raised thereunder, the Person with whom
such Subsequent Placement shall be effected, and attached to which shall be a
term sheet or similar document relating thereto and (B) the Purchaser shall not
have notified the Company by 5:00 p.m. (New York City time) on the tenth (10th)
Trading Day after its receipt of the Subsequent Placement Notice of its
willingness to provide (or to cause its sole designee to provide), subject to
completion of mutually acceptable documentation, financing to the Company on
substantially the terms set forth in the Subsequent Placement Notice. If the

States of America, in cash or by certified or official bank check or checks, all
as specified by the Holder in the Form of Election to Purchase, the Company
shall promptly (but in no event later than 3 business days after the Date of
Exercise) issue or cause to be issued and cause to be delivered to or upon the
written order of the Holder and in such name or names as the Holder may
designate, a certificate for the Warrant Shares issuable upon such exercise,
free of restrictive legends other than as required by applicable law. Any person
so designated by the Holder to receive Warrant Shares shall be deemed to have
become holder of record of such Warrant Shares as of the Date of Exercise of
this Warrant.

            A "Date of Exercise" means the date on which the Company shall have
received (i) this Warrant (or any New Warrant, as applicable), with the Form of
Election to Purchase attached hereto (or attached to such New Warrant)
appropriately completed and duly signed, and (ii) payment of the Exercise Price
for the number of Warrant Shares so indicated by the holder hereof to be
purchased.

            (c) This Warrant shall be exercisable, either in its entirety or,
from time to time, for a portion of the number of Warrant Shares. If less than
all of the Warrant Shares which may be purchased under this Warrant are
exercised at any time, the Company shall issue or cause to be issued, at its
expense, a New Warrant evidencing the right to purchase the remaining number of
Warrant Shares for which no exercise has been evidenced by this Warrant.

         4. Piggyback Registration Rights. During the term of this Warrant, the
Company may not file any registration statement with the Securities and Exchange
Commission (other than registration statements of the Company filed on Form S-8
or Form S-4, each as promulgated under the Securities Act of 1933, as amended
(the "Securities Act"), pursuant to which the Company is registering securities
pursuant to a Company employee benefit plan or pursuant to a merger, acquisition
or similar transaction including supplements thereto, but not additionally filed
registration statements in respect of such securities) at any time when there is
not an effective registration statement covering the resale of the Warrant
Shares and naming the Holder as a selling stockholder thereunder, unless the
Company provides the Holder with not less than 20 days notice of its intention
to file such registration statement and provides the Holder the option to
include any or all of the applicable Warrant Shares therein. The piggyback
registration rights granted to the Holder pursuant to this Section shall
continue until all of the Holder's Warrant Shares have been sold in accordance
with an effective registration statement or upon the Expiration Date. The
Company will pay all registration expenses in connection therewith.

         5. Demand Registration Rights. At any time during the term of this
Warrant when the Warrant Shares are not registered pursuant to an effective
registration statement, the Holder may make a written request for the
registration under the Securities Act (a "Demand Registration"), of all of the
Warrant Shares (the "Registrable Securities"), and the Company shall use its
best efforts to effect such Demand Registration as promptly as possible, but in
any case within 90 days thereafter. Any request for a Demand Registration shall
specify the aggregate number of Registrable Securities proposed to be sold and
shall also specify the intended method of disposition thereof. The right to
cause a registration of the Registrable Securities under this Section 5 shall be
limited to one such registration. In any registration initiated as a Demand
Registration, the Company will pay all of its registration expenses in
connection therewith. A Demand Registration shall not be counted as a Demand
Registration hereunder until the registration statement filed pursuant to the
Demand Registration has been declared effective by the Securities and Exchange
Commission and maintained continuously effective for a period of at least 360
days or such shorter period when all Registrable Securities included therein
have been sold in accordance with such registration statement, provided, however
that any days on which such registration statement is not effective or on which
the Holder is not permitted by the Company or any governmental authority to sell
Warrant Shares under such registration statement shall not count towards such
360 day period.

         6. Payment of Taxes. The Company will pay all documentary stamp taxes
attributable to the issuance of Warrant Shares upon the exercise of this
Warrant; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect


                                      -3-
<PAGE>   4

of any transfer involved in the registration of any certificates for Warrant
Shares or Warrants in a name other than that of the Holder, and the Company
shall not be required to issue or cause to be issued or deliver or cause to be
delivered the certificates for Warrant Shares unless or until the person or
persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid. The Holder shall be responsible for all other tax
liability that may arise as a result of holding or transferring this Warrant or
receiving Warrant Shares upon exercise hereof.

         7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen
or destroyed, the Company shall issue or cause to be issued in exchange and
substitution for and upon cancellation hereof, or in lieu of and substitution
for this Warrant, a New Warrant, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and indemnity, if
requested, satisfactory to it. Applicants for a New Warrant under such
circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable charges as the Company may prescribe.

         8. Reservation of Warrant Shares. The Company covenants that it will at
all times reserve and keep available out of the aggregate of its authorized but
unissued Common Stock, solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein provided, the number of Warrant
Shares which are then issuable and deliverable upon the exercise of this entire
Warrant, free from preemptive rights or any other actual contingent purchase
rights of persons other than the Holder (taking into account the adjustments and
restrictions of Section 9). The Company covenants that all Warrant Shares that
shall be so issuable and deliverable shall, upon issuance and the payment of the
applicable Exercise Price in accordance with the terms hereof, be duly and
validly authorized, issued and fully paid and nonassessable.

         9. Certain Adjustments. The Exercise Price and number of Warrant Shares
issuable upon exercise of this Warrant are subject to adjustment from time to
time as set forth in this Section 9. Upon each such adjustment of the Exercise
Price pursuant to this Section 9, the Holder shall thereafter prior to the
Expiration Date be entitled to purchase, at the Exercise Price resulting from
such adjustment, the number of Warrant Shares obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant Shares issuable upon exercise of this Warrant immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

            (a) If the Company, at any time while this Warrant is outstanding,
(i) shall pay a stock dividend (except scheduled dividends paid on outstanding
preferred stock as of the date hereof which contain a stated divided rate) or
otherwise make a distribution or distributions on shares of its Common Stock (as
defined below) or on any other class of capital stock and not the Common Stock)
payable in shares of Common Stock, (ii) subdivide outstanding shares of Common
Stock into a larger number of shares, or (iii) combine outstanding shares of
Common Stock into a smaller number of shares, the Exercise Price shall be
multiplied by a


                                      -4-
<PAGE>   5

fraction of which the numerator shall be the number of shares of Common Stock
(excluding treasury shares, if any) outstanding before such event and of which
the denominator shall be the number of shares of Common Stock (excluding
treasury shares, if any) outstanding after such event. Any adjustment made
pursuant to this Section shall become effective immediately after the record
date for the determination of stockholders entitled to receive such dividend or
distribution and shall become effective immediately after the effective date in
the case of a subdivision or combination, and shall apply to successive
subdivisions and combinations.

            (b) In case of any reclassification of the Common Stock, any
consolidation or merger of the Company with or into another person, the sale or
transfer of all or substantially all of the assets of the Company or any
compulsory share exchange pursuant to which the Common Stock is converted into
other securities, cash or property, then the Holder shall have the right
thereafter to exercise this Warrant only into the shares of stock and other
securities and property receivable upon or deemed to be held by holders of
Common Stock following such reclassification, consolidation, merger, sale,
transfer or share exchange, and the Holder shall be entitled upon such event to
receive such amount of securities or property equal to the amount of Warrant
Shares such Holder would have been entitled to had such Holder exercised this
Warrant immediately prior to such reclassification, consolidation, merger, sale,
transfer or share exchange. The terms of any such consolidation, merger, sale,
transfer or share exchange shall include such terms so as to continue to give to
the Holder the right to receive the securities or property set forth in this
Section 9(b) upon any exercise following any such reclassification,
consolidation, merger, sale, transfer or share exchange.

            (c) If the Company, at any time while this Warrant is outstanding,
shall distribute to all holders of Common Stock (and not to holders of this
Warrant) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security (excluding those referred to in Sections
9(a), (b) and (d)), then in each such case the Exercise Price shall be
determined by multiplying the Exercise Price in effect immediately prior to the
record date fixed for determination of stockholders entitled to receive such
distribution by a fraction of which the denominator shall be the Exercise Price
determined as of the record date mentioned above, and of which the numerator
shall be such Exercise Price on such record date less the then fair market value
at such record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding share of Common Stock as determined by
the Company's independent certified public accountants that regularly examines
the financial statements of the Company (an "Appraiser").

            (d) If, at any time while this Warrant is outstanding, the Company
shall issue or cause to be issued rights or warrants to acquire or otherwise
sell or distribute shares of Common Stock to all holders of Common Stock for a
consideration per share less than the Exercise Price then in effect, then,
forthwith upon such issue or sale, the Exercise Price shall be reduced to the
price (calculated to the nearest cent) determined by multiplying the Exercise
Price in effect immediately prior thereto by a fraction, the numerator of which
shall be the sum of (i) the number of shares of Common Stock outstanding
immediately prior to such issuance, and (ii) the number


                                      -5-
<PAGE>   6

of shares of Common Stock which the aggregate consideration received (or to be
received, assuming exercise or conversion in full of such rights, warrants and
convertible securities) for the issuance of such additional shares of Common
Stock would purchase at the Exercise Price, and the denominator of which shall
be the sum of the number of shares of Common Stock outstanding immediately after
the issuance of such additional shares. Such adjustment shall be made
successively whenever such an issuance is made.

            (e) For the purposes of this Section 9, the following clauses shall
also be applicable:

                (i) Record Date. In case the Company shall take a record of the
holders of its Common Stock for the purpose of entitling them (A) to receive a
dividend or other distribution payable in Common Stock or in securities
convertible or exchangeable into shares of Common Stock, or (B) to subscribe for
or purchase Common Stock or securities convertible or exchangeable into shares
of Common Stock, then such record date shall be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold
upon the declaration of such dividend or the making of such other distribution
or the date of the granting of such right of subscription or purchase, as the
case may be.

                (ii) Treasury Shares. The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or for
the account of the Company, and the disposition of any such shares shall be
considered an issue or sale of Common Stock.

            (f) All calculations under this Section 9 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

            (g) Whenever the Exercise Price is adjusted pursuant to Section 9(c)
above, the Holder, after receipt of the determination by the Appraiser, shall
have the right to select an additional appraiser (which shall be a nationally
recognized accounting firm), in which case the adjustment shall be equal to the
average of the adjustments recommended by each of the Appraiser and such
appraiser. The Holder shall promptly mail or cause to be mailed to the Company,
a notice setting forth the Exercise Price after such adjustment and setting
forth a brief statement of the facts requiring such adjustment. Such adjustment
shall become effective immediately after the record date mentioned above.

            (h) If:

                (i) the Company shall declare a dividend (or any other
distribution) on its Common Stock; or


                                      -6-
<PAGE>   7

                (ii) the Company shall declare a special nonrecurring cash
dividend on or a redemption of its Common Stock; or

                (iii) the Company shall authorize the granting to all holders of
the Common Stock rights or warrants to subscribe for or purchase any shares of
capital stock of any class or of any rights; or

                (iv) the approval of any stockholders of the Company shall be
required in connection with any reclassification of the Common Stock of the
Company, any consolidation or merger to which the Company is a party, any sale
or transfer of all or substantially all of the assets of the Company, or any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property; or

                (v) the Company shall authorize the voluntary dissolution,
liquidation or winding up of the affairs of the Company,

then the Company shall cause to be mailed to each Holder at their last addresses
as they shall appear upon the Warrant Register, at least 30 calendar days prior
to the applicable record or effective date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of Common Stock of
record shall be entitled to exchange their shares of Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up; provided, however, that the failure to mail such notice or any
defect therein or in the mailing thereof shall not affect the validity of the
corporate action required to be specified in such notice.

         10. Payment of Exercise Price. The Holder may pay the Exercise Price in
one of the following manners:

             (a) Cash Exercise. The Holder shall deliver immediately available
funds; or


                                      -7-
<PAGE>   8

            (b) Cashless Exercise. The Holder shall surrender this Warrant to
the Company together with a notice of cashless exercise, in which event the
Company shall issue to the Holder the number of Warrant Shares determined as
follows:

                       X = Y (A-B)/A
         where:
                       X = the number of Warrant Shares to be issued to the
                       Holder.

                       Y = the number of Warrant Shares with respect to which
                       this Warrant is being exercised.

                       A = the average of the closing sale prices of the Common
                       Stock for the five (5) trading days immediately prior to
                       (but not including) the Date of Exercise.

                       B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have been
commenced, on the issue date.

            11. Fractional Shares. The Company shall not be required to issue or
cause to be issued fractional Warrant Shares on the exercise of this Warrant.
The number of full Warrant Shares which shall be issuable upon the exercise of
this Warrant shall be computed on the basis of the aggregate number of Warrant
Shares purchasable on exercise of this Warrant so presented. If any fraction of
a Warrant Share would, except for the provisions of this Section 11, be issuable
on the exercise of this Warrant, the Company shall pay an amount in cash equal
to the Exercise Price multiplied by such fraction.

            12. Notices. Any and all notices or other communications or
deliveries hereunder shall be in writing and shall be deemed given and effective
on the earliest of (i) the date of transmission, if such notice or communication
is delivered via facsimile at the facsimile telephone number specified in this
Section prior to 4:30 p.m. (Eastern time) on a business day, (ii) the business
day after the date of transmission, if such notice or communication is delivered
via facsimile at the facsimile telephone number specified in this Section later
than 4:30 p.m. (Eastern time) on any date and earlier than 11:59 p.m. (Eastern
time) on such date, (iii) the business day following the date of mailing, if
sent by nationally recognized overnight courier service, or (iv) upon actual
receipt by the party to whom such notice is required to be given. The addresses
for such communications shall be: (i) if to the Company, to 12201 Technolgy
Blvd., Suite 125, Austin, TX 78727-6101 Attention: Chief Financial Officer, or
to facsimile no. (512) 257-5351, or (ii) if to the Holder, to the Holder at the
address or facsimile number appearing on


                                      -8-
<PAGE>   9

the Warrant Register or such other address or facsimile number as the Holder may
provide to the Company in accordance with this Section 12.

            13. Warrant Agent.

                (a) The Company shall serve as warrant agent under this Warrant.
Upon thirty (30) days' notice to the Holder, the Company may appoint a new
warrant agent.

                (b) Any corporation or other entity into which the Company or
any new warrant agent may be merged or any corporation or other entity resulting
from any consolidation to which the Company or any new warrant agent shall be a
party or any corporation or other entity to which the Company or any new warrant
agent transfers substantially all of its corporate trust or shareholders
services business shall be a successor warrant agent under this Warrant without
any further act. Any such successor warrant agent shall promptly cause notice of
its succession as warrant agent to be mailed (by first class mail, postage
prepaid) to the Holder at the Holder's last address as shown on the Warrant
Register.

            14. Miscellaneous.

                (a) This Warrant shall be binding on and inure to the benefit of
the parties hereto and their respective successors and permitted assigns. This
Warrant may be amended only in writing signed by the Company and the Holder.

                (b) Subject to Section 14(a), above, nothing in this Warrant
shall be construed to give to any person or corporation other than the Company
and the Holder any legal or equitable right, remedy or cause under this Warrant.
This Warrant shall inure to the sole and exclusive benefit of the Company and
the Holder.

                (c) This Warrant shall be governed by and construed and enforced
in accordance with the internal laws of the State of New York without regard to
the principles of conflicts of law thereof.

                (d) The headings herein are for convenience only, do not
constitute a part of this Warrant and shall not be deemed to limit or affect any
of the provisions hereof.

                (e) In case any one or more of the provisions of this Warrant
shall be invalid or unenforceable in any respect, the validity and
enforceability of the remaining terms and provisions of this Warrant shall not
