products and services of the Tanisys Group include custom design, 
engineering, memory test equipment, standard and custom memory modules, 
patented touch technology, manufacturing, testing and logistics services.

    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.  On June 
30, 1993, the Company continued its corporate charter into 

                                      3
<PAGE>

the State of Wyoming and on July 11, 1994, changed its name to Tanisys 
Technology, Inc.  The Company's Common Stock currently trades on the VSE 
under the symbol "TNS.U," quoted in U.S. dollars.

    Through its recent acquisitions of 1st Tech and DarkHorse, the Tanisys 
Group has become a leading manufacturer of specialty modules, standard and 
custom memory modules and memory test systems for a wide variety of 
electronic system applications and industries.  The Tanisys Group has 
extensive design, engineering, manufacturing, logistics and test 
expertise, which management believes provides it with significant

resellers ("VARs") and system integrators.  OEM customers include Bay 
Networks, Inc., Compaq Computer Corporation, Dell Products LP, 
Hewlett-Packard Company, Siemens AG Semiconductors and Toshiba Corporation

RECENT DEVELOPMENTS

    On November 20, 1996, the Tanisys Group signed two contracts with 
Siemens Components, Inc. ("Siemens") to provide design engineering, 
quick-turn manufacturing, warehousing, distributing and testing of memory 
modules for Siemens and their customers.  Under the terms of the 
agreements, Siemens is capitalizing on the quick-turn manufacturing and 
logistics services provided by the Tanisys Group in order to better 
service their customers and to support them in inventory reduction and 
management.  The consummation of these agreements is in fulfillment of the 
Tanisys Group's strategy and represents an important milestone in 
establishing long-term relationships with major customers as the primary 
provider of turnkey design, development and manufacturing solutions.

INDUSTRY OVERVIEW

    The demand for electronic products and components has grown 
dramatically over the last several years as a result of expanding unit 
sales in a number of industries, including computer, appliance, 
telecommunications, consumer electronics and automotive, with expansion 
into other industries ongoing.  The demand for greater functionality and 
product integration has required electronics manufacturers to increase the 
number and complexity of electronic devices incorporated into their 
products.  As a result of this trend, the Tanisys Group believes that the 
percentage of total product costs represented by electronic assemblies has 
risen steadily over the past few years.  Integrated Circuit Engineering 
("ICE"), an independent data source, determined that in 1995 the total 
worldwide market for semiconductor devices exceeded $120 billion.

    Memory integrated circuits encompass several types of devices designed 
to perform specific functions within computer and other electronic 
systems.  The most significant categories of semiconductor memory are 
dynamic random access memory ("DRAM"), static random access memory 
("SRAM") and non-volatile memory, including Flash, in addition to an 
emerging technology known as synchronous DRAM ("SDRAM" or "SyncDRAM").  
DRAM provides large capacity "main" memory; SRAM provides specialized high 
speed memory; Flash and other non-volatile memory provide low power memory 
that retains data after a system is turned off; and SyncDRAM is quickly 
becoming the replacement for ("FPM") DRAM.  In addition, within each of 
these broad categories of memory products, semiconductor manufacturers are 
offering an increasing variety of memory devices that are designed for 
application specific uses.

    The growth in semiconductor memory devices has created an increased 
demand for reliable, cost-effective testing solutions.  Historically, 
memory testing has been the primary responsibility of the memory 
semiconductor companies due to the expensive equipment required for the 
process.  However, as the industry matures, the need for memory test 
capability has extended into OEMs, VARs, retail outlets, service centers 
and end users.  This need for increased testing is being driven by 
stringent quality requirements, increased production volume, new complex 
memory solutions, loss prevention and customer expectations. Tanisys Group 
management estimates the worldwide memory test market for 1997 to be 
approximately $29 million in revenue, which represents an estimated 33% 
increase over 1996.  Management estimates that desktop testers, used by 
high volume customers such as OEMs, semiconductor manufacturers and VARs, 
represent approximately 52% of the projected market and that portable 
testers, used by retailers, third-party service companies and VARs, 
represent approximately 48% of the projected market.  The increase in 
memory complexity and the shear number of products continues to fuel 
significant growth in this market.

    The proliferation of electronic devices throughout the world has 
necessitated new approaches to providing intuitive personal access to the 
products and their applications.  The Tanisys Touch product line competes 
in this area through its capacitive touch technology.  Any product that 
uses switches or controls is 
                                      5
<PAGE>

a candidate for the application of this 
technology, including appliances, personal computers, point-of-sale 
terminals, automated teller machines ("ATMs"), gas pumps, multimedia 
kiosks, industrial and medical equipment, financial systems, 
computer-based training systems, gaming machines and many other electronic 
devices used by the public.  Consistent across industries manufacturing 
these products is the search for low cost, highly reliable, intuitive user 
access.  In 1996, the personal computer industry is projected to sell 63.7 
million units for both desktop and notebook systems according to 
Dataquest, Inc., a market research firm.  Additionally, the appliance 
industry is expected to sell in excess of $3 billion in units worldwide in 
1996.

DESIGN, ENGINEERING, MANUFACTURING AND LOGISTICS SERVICES

    The increased cost of capital equipment as well as the complexity and 
expertise required to set up and operate an electronic manufacturing 
operation has resulted in the trend of outsourcing by OEMs.  By 
outsourcing design, manufacturing and logistics functions, OEMs are able 
to focus their resources on their own areas of core competence and 
competitive advantage, such as unique technology, system design and 
marketing capabilities.  OEM outsourcing practices range from contract 
manufacturing, in which the OEM may turn to an outside supplier to procure 
components and design and manufacture a specific product for the OEM on a 
turnkey basis, to consignment, in which the OEM employs the outside 
supplier to design, engineer, manufacture, maintain inventory and 
distribute a product using  components supplied by the OEM.

    One of the most significant opportunities is the manufacture of memory 
modules.  Memory modules are compact circuit board assemblies consisting 
of DRAM, SRAM, Flash or other semiconductor memory devices and related 
circuitry. The suppliers of memory modules include semiconductor 
manufacturers who maintain captive memory module production facilities and 
independent memory module manufacturers that source memory devices from a 
wide variety of suppliers. Although some semiconductor manufacturers have 
the ability to manufacture significant volumes of standard memory modules, 
generally these companies are focused on adding value through their 
silicon expertise, rather than through their memory module manufacturing 
capabilities.  Management of the Tanisys Group believes that the business 
models of most semiconductor manufacturers may not adequately address 
OEMs' changing requirements for a broad range of custom and application 
specific products.

    Independent manufacturers of memory modules have experience with a 
broad range of memory devices and offer substantial expertise in component 
selection and module product development.  Due to the fact that 
independent manufacturers do not produce their own semiconductor devices, 
they have the ability to mix and match devices from a variety of 
semiconductor suppliers in a single memory module.  Independent 
manufacturers of memory modules currently address two primary market 
segments: the OEM channel and the personal computer reseller channel.  
Suppliers to the OEM channel typically offer custom and application 
specific modules to the workstation and telecommunications industries, as 
well as standard memory modules for use by computer and peripheral OEMs.  
Suppliers to the personal computer reseller channel typically offer 
standard DRAM memory modules as an upgrade product sold through computer 
distributors and retail channels.

MEMORY TEST SYSTEMS

    The memory test market is growing rapidly due to the increasing and 
ever changing complexities, configurations, densities and technologies of 
memory devices.  Semiconductor manufacturers are the major 

                                      6
<PAGE>

users of memory test systems on a chip level as well as on modules.  In 
addition, the market extends into independent manufacturers of modules, OEMs, 
retail outlets, service centers and end users.  The Tanisys Group believes 
that the desire to produce as well as purchase quality memory products is 
driving an increased awareness of the need for memory testing.

    Memory test systems can be classified into two main areas:  
semiconductor chip level testers and memory module testers.  Semiconductor 
chip level testers are utilized to completely characterize a semiconductor 
device to guarantee its performance to a standard set of specifications.  
Memory module testers are utilized to characterize an assembly of 
semiconductor devices to a desired specification, whether standard or 
custom.  This characterization and testing is done to insure quality of 
performance following a manufacturing process.

    Test systems generally are designed as generic testers that must be 
programmed and customized by the user to a specific purpose.  The testers 
may be configured to test personal computer motherboards, controllers or 
simply memory modules.  The common features these testers provide are 
their abilities to manipulate the semiconductors' inputs and outputs in 
relation to time at various voltages.  The patterns of tests are known as 
test algorithms or test vectors.

MEMORY MODULES

    Electronic systems increasingly employ memory modules as building 
blocks in system design as a result of the many advantages memory modules 
offer OEMs and end users.  The use of memory modules enables OEMs to offer 
a relatively easy path for upgradeability of a personal computer or 
workstation, a feature of system design that is increasingly required by 
end users.  The use of memory modules allows OEMs to increase flexibility 
by enabling them to easily configure a system with a variety of different 
levels of memory, thus enabling OEMs to address multiple price points or 
applications with a single base system design. To achieve this 
upgradeability and flexibility, both personal computer and communications 
OEMs frequently design their systems to use memory modules as a "daughter 
card," reducing the need to include memory devices on the motherboard. 
This design structure frees space on the motherboard and enables the OEM 
to use a single motherboard as a common central element for a variety of 
different systems, resulting in significant cost savings.  The use of 
memory modules further reduces OEMs' costs by allowing them to add 
expensive memory devices to products during the final stages of the 
manufacturing process, thereby reducing the need for work-in-process 
inventories.

    The market for memory modules includes both standard and custom 
modules. The high volume standard memory module market includes modules 
that can be sourced from many module suppliers and are designed to be 
incorporated into a wide variety of equipment.  These modules employ 
designs meeting widely used industry specifications of the Joint 
Electronic Development Engineering Council ("JEDEC"), primarily utilizing 
DRAM memory, and are available with a variety of options to address the 
needs of multiple OEMs.  Standard memory modules typically are used in 
desktop personal computers and printers and are both to both OEMs and 
through computer resellers directly to end users.

    Specialty memory modules include both custom and application specific 
modules.  The varying requirements of different electronic systems and the 
increased number of memory device options have resulted in a market for 
custom memory modules that are designed to enhance the performance of a 

                                      7
<PAGE>

particular system or a set of applications.  These modules are usually 
based on either DRAM, SyncDRAM, SRAM or Flash technologies and may include 
additional control circuitry.  Custom memory modules typically are sourced 
from a limited number of suppliers.  Application specific or custom memory 
modules generally are used in mobile computers, workstations and 
telecommunications devices, such as routers and switches, and are sold 
primarily to OEMs.

CAPACITIVE TOUCH TECHNOLOGY

    Capacitive touch is input technology that utilizes the sensing of 
touch with a high speed microprocessor circuit, replacing mechanical input 
devices. There are relatively few companies pursuing this technology, and 
to the best knowledge of management of the Tanisys Group, there are no 
other companies pursuing off-screen applications other than mouse 
replacement applications. Mouse replacement technology involves five to 
six layers of board that are relatively expensive to produce.  However, 
off-screen applications offer a wide range of opportunities for the 
technology, such as gas pumps, appliances, ATMs, cellular telephones and 
almost any other electronic appliance, and the microchips are relatively 
inexpensive to produce.

THE DRAM MARKET

    DYNAMIC RANDOM ACCESS MEMORY.  A DRAM is a high density, low cost per 
bit semiconductor device that stores digital information in the form of 
bits and provides high speed storage and retrieval of data.  DRAMs are the 
most widely used semiconductor memory component in most PC systems.  The 
development of more powerful personal computers and workstations and the 
increasing emphasis on high-throughput networking and telecommunications 
products have resulted in the need for higher volumes and greater 
varieties of DRAM memory in electronic systems.  For example, personal 
computers currently based on 486, Pentium-Registered Trademark- and 
PowerPC-Registered Trademark- microprocessors frequently employ 8 to 16 
megabytes ("Mbytes") of DRAM, which is significantly more memory than that 
employed by older generation personal computers.  The adoption of Windows 
95 and NT and other advanced operating systems is further increasing the 
need for DRAM, as 16 Mbytes of DRAM memory are required for higher 
performance to support Windows 95 multitasking capabilities.

THE SRAM MARKET

    STATIC RANDOM ACCESS MEMORY.  A SRAM is a semiconductor device that 
performs memory functions much the same as a DRAM, but does not require 
its memory cells to be electronically refreshed.  In addition, a SRAM can 
be designed to operate faster than a DRAM.  A SRAM contains more complex 
electronic circuitry than a DRAM and consequently has higher per bit 
production costs.  The market for SRAMs includes the high speed SRAM 
segment and the low power SRAM segment.  The market for high speed SRAM 
devices has grown rapidly over the last few years, driven primarily by the 
inability of slower DRAM devices to support the increasing speed 
requirements of personal computer and data communications systems.  Due to 
existing architectural limitations, DRAM speeds have not increased 
commensurably with improvements in microprocessor speeds.  DRAMs typically 
operate at 10 to 20 megahertz ("Mhz"), or 100 to 50 nanoseconds ("ns"), 
while microprocessor bus speeds for most Pentium-Registered 
Trademark--class personal computers currently sold are 66 MHz (15 ns) or 
higher.  Operating at 66 MHz or faster, high performance SRAM devices can 
be used as "cache" memory, which increases a system's performance.  For 
example, in a 
                                      8
<PAGE>

personal computer or workstation, L2 cache memory can 
increase system performance by acting as an intermediary between fast 
microprocessors and slower DRAM main memory.  In disk drives, SRAM cache 
memories can be used as a high speed buffer to accelerate data throughput 
from the drive to the system bus.

    The Tanisys Group's SRAM family focuses on the high performance, or 
"Very Fast," sector of the SRAM market, supporting cache memory 
requirements in computers. Very Fast SRAM provides access times 
approximately five times faster than those of a DRAM.  The market for Very 
Fast SRAM has grown with the number of applications that require a 
"buffer" or "cache" of high speed memory between the central processing 
unit and the main DRAM-based memory.

    High speed SRAMs are experiencing rapid advancements in speed, 
architecture, organization, density and operating voltages.  These 
advancements are primarily necessitated by the increasing speed and 
functionality of microprocessors such as the Pentium-Registered 
Trademark-, the PowerPC-Registered Trademark-, the Alpha-Registered 
Trademark- and the SPARC-Registered Trademark-.  High speed SRAMs are 
reaching access times below 3 ns.  High speed SRAM architecture has 
evolved from asynchronous random access to synchronous pipelined burst 
mode corresponding with the Pentium-Registered Trademark- architecture, 
and synchronous serial access corresponding with reduced instruction set 
computing ("RISC") architectures.  SRAM devices are available in 
organizations ranging from 1 bit to 36 bits wide and densities of up to 4 
megabits.  In addition, industry trends toward lower voltage 
microprocessors, such as the Intel P54C (3.3 volt Pentium-Registered 
Trademark-), have created a need for new, low voltage SRAM cache memories.

    Low power SRAM devices are used primarily in computing or industrial 
applications in which efficient power management is of greatest 
importance. Primary applications for low power SRAM devices include mobile 
computing and other environments in which electronic systems rely on 
battery power or require low power dissipation.

THE FLASH MEMORY MARKET

    Flash memory is an application of non-volatile memory used to retain 
stored data after a system's power has been turned off.  The ability of 
Flash devices to be electronically rewritten to update parameters or 
system software provides greater flexibility and ease of use than other 
non-volatile memory devices, such as older erasable programmable read only 
memory ("EPROM") devices.  Flash memory is one of the fastest growing 
segments of the memory market, as a growing range of applications utilize 
Flash memory in the computer, telecommunications, networking, consumer 
electronics, automotive, industrial control and instrumentation 
industries.  For example, Flash memory can be used in communication 
devices such as routers, in which Flash memory provides storage of control 
programs and system-critical data.  Another common application for Flash 
memory is in PC cards, which are small form factor devices that are 
inserted into notebook and subnotebook computers and consumer electronics 
products such as personal digital assistants ("PDAs") and digital cameras 
to provide added storage.

    Due to the increasing number of Flash suppliers, a variety of Flash 
architectures such as NOR, DINOR, NAND and AND have become available.  
These devices are offered in an increasing number of operating modes, such 
as random access, serial access, synchronous and DRAM-like, and in a range 
of operating voltages from 3.3 v. to 12.0v. 

                                      9

THE SYNCDRAM MARKET

    The introduction of the SyncDRAM as a replacement of FPM DRAM, which 
is currently occurring, is considered to be a major shift in computing 
system architecture creating the requirement to redesign  the memory 
system control logic.  SyncDRAM is unique in that the memory can be 
accessed by the processor in a synchronous instead of asynchronous manner, 
which is inherently a faster operation.  This transition will create the 
demand for a total redesign of memory modules and require new testing 
equipment to implement its use.

PRODUCTS AND SERVICES

    The products and services of the Tanisys Group are divided into three 
basic categories based on the areas of product specialization of each of 
the three companies that comprise the consolidated group.  These products 
and services are custom design, engineering, standard and custom memory 
modules, manufacturing, testing, logistics services, memory test equipment 
and patented touch technology.  Memory module products represented 
approximately 95%, 97% and 97% of the Tanisys Group's total net sales in 
fiscal 1996, 1995 and 1994, respectively, on a pro forma basis, and 
semiconductor memory product testing equipment represented substantially 
all of the balance of the Tanisys Group's revenue.

RESEARCH, DESIGN ENGINEERING AND PROTOTYPE TECHNOLOGIES SERVICES

    The Tanisys Group believes it is proactively responding to the 
increasing competition and shorter product life cycles that its customers 
are facing in their respective industries.  The Tanisys Group's design 
engineers work jointly with customers to design products that will exceed 
the minimum requirements and specifications for functionality, quality and 
reliability.  The transition from concept to prototype to a performance 
reliable, manufacturable product with planned production requirements is 
expertly managed so that the product volume-to-market cycle is as short as 
possible, saving both time and expense.  This process is aided by the 
quick-turn capabilities in the Tanisys Group's manufacturing and surface 
mount assembly processes.  The Tanisys Group's intent is to position 
itself to be the manufacturer of choice due to its intimate knowledge of 
the product and the customers' requirements.

SURFACE MOUNT ASSEMBLY SERVICES

    The Tanisys Group has a substantial investment in various pieces of 
specialized module assembly equipment, including five Quad Systems, Inc. 
surface mount technology ("SMT") machines, DarkHorse and Terradyne, Inc. 
("Terradyne") testing equipment, reflow soldering machines, a sophisticated 
hand-drop assembly line and board washing equipment.  The SMT process solders 
the leads on integrated circuits and other electronic components to the 
surface of the printed circuit board ("PCB"), which replaces older 
pin-through-hole technology. The SMT process accommodates substantially 
greater density than can be achieved with the older technologies.  This 
allows for a reduction in the size of the PCB, enhances the performance of 
the module and usually reduces the costs of materials and components.  
Advanced SMT technologies, including double-sided attachment of components 
and fine pitch component placement on the PCBs, have further increased 
component density, reduced the PCB size and achieved substantial economies in 
the cost of the finished modules.  Double-sided placement attaches SMT 
components on both sides of the 

                                      10
<PAGE>

PCB, and fine-pitch SMT places components that have tightly spaced 
leads.  Substantially all of the modules assembled by the Tanisys Group 
employ the SMT process, and an increasing percentage utilizes fine-pitch 
component placement and/or double-sided component attachment.  The Tanisys 
Group intends to continue investing in the equipment and technologies 
required to develop the resources required to exceed customers' 
expectations and requirements.

SEMICONDUCTOR MEMORY TESTING EQUIPMENT

    The DarkHorse testers are designed, maintained and enhanced by the 
Tanisys Group's professional engineering staff.  The current emphasis is 
on development of a tester for the new and growing SyncDRAM portion of the 
module industry. Phase 1 of this development, which has been completed, 
consisted of designing attachments which allow the current models to test 
the new SyncDRAM modules. New testers that are designed specifically for 
the new SyncDRAMs are now in the development stage.

    All of the DarkHorse testers are designed and manufactured by the 
Tanisys Group's manufacturing operation, utilizing the SMT process and the 
hand-drop line.  The Tanisys Group's commitment to continuous quality 
improvement in its manufacturing operation has been essential to the 
success of this product line. DarkHorse currently offers two testers, the 
Sigma 2 and the Sigma LC, which compete in the automatic testing equipment 
("ATE") market for the testing of both chips and modules. DarkHorse's 
competitors include Terradyne, Terradyne/Megatest Division of Terradyne 
("Megatest") and Realm Systems, Inc. ("Realm"), all of which provide 
generic test equipment that requires the user to custom program the 
equipment for specific applications.  The DarkHorse test systems are 
pre-programmed and include an extensive set of pre-programmed algorithms 
and test programs that are accessed through an intuitive user interface.

    SIGMA 2.  The Sigma 2 unit is geared toward accurate, extensive and 
expedient testing of memory for the manufacturer who needs additional 
parametric testing and performs large volume testing, such as 
manufacturers of personal computers and other electronic products.  The 
Sigma 2 has additional tests not available on the Sigma LC, which are 
demanded in high-end testing environments.

    SIGMA LC.  The Sigma LC unit is portable and tests memory in the same 
accurate, extensive and expedient manner as Sigma 2, but is geared toward 
single in-line memory module ("SIMM") users whose volume is lower and 
whose testing needs are slightly less extensive.  The market for the Sigma 
LC ranges from in-house service technicians to memory manufacturers.

MEMORY MODULES

    The Tanisys Group designs and markets over 400 products consisting of 
memory modules, which include DRAM, SRAM, SyncDRAM and Flash memory.  The 
products offered include custom and application specific memory modules, 
as well as standard memory modules that comply with industry standards 
established by JEDEC.  The target market segments for these products 
include personal computers, mission critical servers, telecommunications/
data communications, custom electronic assemblies, memory products and 
contract manufacturing services to the electronics market.  Historically, 
the majority of the Tanisys Group's revenues have come from sales of standard 
products to the memory 

                                      11
<PAGE>


after-market as well as custom products and custom assembly for the OEM 
markets using advanced surface mount technologies and manufacturing processes.

    An important aspect of the Tanisys Group manufacturing operations is 
its focus on product testing.  The Tanisys Group tests 100% of its memory 
modules for full functionality.  The Tanisys Group believes that it has 
established substantial technical expertise in the testing of memory 
modules, and its staff of experienced test engineers develop proprietary 
testing routines and parameters that enable it to diagnose problems in 
system design or memory components, to characterize the performance of new 
products and to provide high quality products in volume.

TOUCH TECHNOLOGY

    Tanisys Touch is a proprietary technology which is integrated into 
electronic products to provide greater ease of use.  Tanisys Touch allows 
manufacturers to create devices that can be controlled simply by using 
your finger.  This intuitive characteristic means that users can rely more 
on simple touch controls rather than on complex user control interfaces.  
Tanisys Touch has the following advantages:  no moving parts, lower cost 
of implementation, the ability to be mounted under a variety of materials, 
expanded ease-of-use functionality, environmentally robust and monolithic 
construction that can be mounted directly to the surface of products, 
including compound curves.  While applicable markets for touch include any 
electronic device, the initial focus is on computers and appliances due to 
market size and product development cycles.

AVAILABILITY OF RAW MATERIALS

    The Tanisys Group's manufacturing operations use numerous suppliers 
for electronic components and materials, including DRAM components, used 
in its operations.  Shortages of certain types of electronic components 
have occurred in the past and may occur in the future.  The Tanisys 
Group's contract manufacturing operations procure materials and components 
based on purchase orders received and accepted from customers while 
seeking to minimize the overall level of inventory.  Component shortages 
or price fluctuations could have an adverse effect on the Tanisys Group's 
business and results of operations.

CUSTOMERS, SALES AND MARKETING

    The Tanisys Group's principal customers include major and second-tier 
electronics OEMs, semiconductor manufacturers, computer and electronics 
distributors, VARs, system integrators and major consumer electronics 
retail outlets.

    On a pro forma basis, approximately 95% of the Tanisys Group's sales 
are derived from the 1st Tech product and service line, which includes 
standard and custom memory modules, custom electronics modules, design, 
engineering, manufacturing and logistical inventory control services.  
Substantially all of the balance of the Tanisys Group's sales are derived 
from the DarkHorse tester product line, which also includes design and 
engineering services, maintenance contracts and consumable replacement 
parts.  In fiscal 1996, the top ten customers of the 1st Tech products 
accounted for 48% of Tanisys Group sales on a pro forma basis, and no one 
customer accounted for 10% or more of such sales.

                                      12
<PAGE>

    The Company believes that it has proven the Tanisys Touch technology 
and that the next step is inclusion of this technology by OEMs in the 
marketplace. This can occur only if the OEM's product designs include the 
technology because the discrete Tanisys Touch technology is not easily 
retrofitted into existing products.  Since July 1995 and prior to the 
acquisitions of 1st Tech and DarkHorse, the Company focused substantially 
all of its time and effort in developing and marketing Tanisys Touch to 
the personal computer and appliance marketplace through major OEMs.  
Currently, the Company is supporting a leading personal computer 
manufacturer to introduce a touch-enabled product.  In addition, the 
Company is working with a leading appliance manufacturer to introduce a 
touch-enabled appliance.  Although both the personal computer manufacturer 
and appliance manufacturer are expending significant resources to develop 
the touch-enabled product lines, the Tanisys Group has no assurance that 
either of these endeavors will be successful.

    The Tanisys Group primarily sells its products and services through 
direct sales in the United States, Europe and Asia and also uses a network 
of independent sales representatives located throughout the United States 
and Europe for certain OEM customers and large retail electronics stores.  
Sales outside these areas are made through distributors, which purchase 
products for resale outside the United States.

    The Tanisys Group's sales and marketing efforts are conducted in an 
integrated process involving direct sales people, independent sales 
representatives, customer service representatives and senior executives.  
An important aspect of the selling cycle is the team approach whereby a 
senior executive is combined with marketing, manufacturing, engineering 
and sales counterparts to work closely with the major OEM and 
semiconductor accounts. Especially important are the related selling 
opportunities of product lines. Conceivably, once a relationship is 
established with an OEM, there is opportunity to sell all product lines 
into the same account.

    Relationships with leading semiconductor manufacturers located in the 
United States, Japan, South Korea, Taiwan and Europe have been developed 
by the Tanisys Group, and many of these vendors are also customers.  The 
Tanisys Group frequently works jointly with these vendors in bidding for 
customer designs to be incorporated into an OEM's system.

    The Tanisys Group plans to expand its sales and marketing organization 
to increase the sales of its products and services and establish Tanisys 
Touch, 1st Tech and DarkHorse brand names worldwide.  Current marketing 
activities include direct mail solicitations and participation in trade 
shows, and future marketing activities also will include advertising in 
trade publications targeted at high technology industries.

    Sales generally are made pursuant to standard purchase orders.  Only 
those customer orders for which purchase orders have been accepted and 
assigned shipment dates within the next 12 months are included in backlog. 
 Because the Tanisys Group's current backlog is subject to change in 
delivery schedules and is subject to cancellation with only limited or no 
penalties, backlog is not necessarily an indication of future net sales.  
There can be no assurances that current backlog will necessarily lead to 
net sales for any future period.  At October 31, 1996, backlog was 
$811,009.

are key elements of the Tanisys Group's strategy:

ESTABLISH THE TANISYS GROUP AS A LEADER IN ENGINEERING AND DESIGN SERVICES

    The Tanisys Group's engineering, design and manufacturing staff 
delivers value-added services, focusing on research, design, prototype, 
development and manufacturing services, and gives the Tanisys Group the 
ability to differentiate itself from competitors that primarily 
concentrate on the manufacturing aspects of the industry.  The Tanisys 
Group believes that its professionals have the creative ability and 
experience to understand a customer's ideas, analyze the technology and 
work with them to create a product design.  They can then proceed with the 
building of the necessary prototypes to prove, design and develop a 
manufacturing model, thereby moving the customer from the concept stage to 
a manufacturable product.  The Tanisys Group maintains a unique advantage 
in the electronics manufacturing services ("EMS") industry through an 
obvious depth of understanding of the product gained by its manufacturing 
staff from its engineering staff.

EXPAND MANUFACTURING AND LOGISTICS CAPACITY AND EXPERTISE

    Further expansion and automation of manufacturing capacity is planned 
through investment in advanced manufacturing equipment, while maintaining 
responsiveness to OEMs through short design cycle and rapid turnaround.  
The Tanisys Group has made and will continue to make investments in 
advanced manufacturing process equipment and technologies, and the Tanisys 
Group will continue to work closely with customers concerning the 
identification and implementation of all advances in process technologies 
needed to design and manufacture new and more complex products.  The 
Tanisys Group believes that it benefits from significant economics of 
scale in procurement and equipment utilization due to its high volume 
manufacturing of a wide variety of memory module products.  An experienced 
manufacturing staff is in place, and automated specialized surface mount 
lines have been established, enabling the manufacture of products in a 
cost effective manner.  An important aspect of the Tanisys Group's 
manufacturing strategy is to focus extensively on product quality to 
address the stringent requirements of leading electronics OEMs worldwide.  
In addition, the Tanisys Group believes that it has established particular 
expertise in materials management through efficient procurement, inventory 
tracking and control and management information systems. 

                                      14

DEVELOP NEW CUSTOMERS FOR EXISTING PRODUCTS AND SERVICES

    The Tanisys Group intends to expand the marketing of its products and 
services worldwide through the use of its in-house sales organization and 
by contracting with independent sales representative organizations that 
have existing relationships with potential customers for other products 
and services. The intent is to establish long-term relationships with 
major OEMs as the primary provider of turnkey design, development and 
manufacturing solutions for new and existing products and services.

EXPAND THE SCOPE OF PRODUCTS AND SERVICES

    The Tanisys Group intends to expand the scope of products and services 
provided to existing customers who are already familiar with the total 
quality focus of the Tanisys Group.  The intent is to establish long-term 
relationships as a primary provider of a complete slate of products and 
services with these customers.  

CONTINUE TO PROVIDE TOTAL QUALITY MANAGEMENT OF PRODUCTION AND BUSINESS 
PROCESSES

    The Tanisys Group continuously endeavors to improve production 
quality, reduce cycle time and provide innovative solutions for customer 
problems.  The combination of full-service component and materials 
purchasing, inventory and materials management and continuous flow 
manufacturing with sophisticated computer-aided design and manufacturing 
capabilities shortens the response time for fulfilling customer requests.  
The Tanisys Group is International Standards Organization ("ISO") 9002 
compliant and is in the process of becoming certified.

EXPAND DEVELOPMENT OF DARKHORSE MEMORY TEST EQUIPMENT PRODUCT LINE

    The requirements for reliable and reasonably priced test 
instrumentation has grown rapidly as customers' emphasis on quality 
control in manufacturing has increased.  The transition to dual in-line 
memory modules ("DIMMs") and SyncDRAMs and the increasingly smaller sizes 
require the design or redesign of sophisticated memory testers.  The 
electronics manufacturing services industry requires larger, more 
automated testers that will work in conjunction with continuous flow 
manufacturing lines, and the increasingly competitive nature of the 
industry necessitates more economic pricing than this type of tester has 
today.  The retail industry requires reliable and reasonably priced 
portable testers for loss prevention with pass/fail testing and for module 
identification purposes.

DEVELOP PRODUCTS USING THE TOUCH TECHNOLOGY

    The Tanisys Touch strategy is focused on the computer and appliance 
industries due to market size and product development cycles, which 
management believes will provide shorter time to revenue than other 
potential industry markets.  Initial focus is on select major 
manufacturers in the computer and appliance industries with license 
agreements used for specific new product development.  This strategy is 
consistent with the overall focus on the high volume OEM type customer as 
opposed to the retail channels.

                                      15
<PAGE>

EXPAND MANUFACTURING CAPABILITIES AND SERVICES

    The intensely competitive nature of the electronics manufacturing 
industry has forced the major competitors to expand the range of products 
and value-added services provided to their principal customers in order to 
serve as single-source providers of a comprehensive and growing set of 
solutions-based products and services.  By providing research, design and 
prototype capabilities, the Tanisys Group can assist a customer in the 
critical development and pre-production planning phase of product 
implementation and follow through with the more traditional manufacturing 
services.  Industry parts suppliers also are customers of the Tanisys 
Group, providing it with direct acquisition channels and thereby creating 
strategic alliances.  This allows a customer to utilize fewer service 
providers to streamline the process and achieve better efficiencies in the 
development cycle due to fewer transitions from one provider to another.  
This type of strategic relationship gives a competitive advantage to both 
the electronics manufacturer and to the customer within their respective 
industries.

    The continuing rapid advances in technology further support customers' 
utilization of outsourcing to companies in the electronics industry.  
Companies operating in the advanced electronic industries must devote more 
and more resources, which ultimately are limited, to the development of 
new technologies either for the next generation of an existing product or 
the development of new products.  Due to continuously reducing sizes and 
increasing higher performance expectations and performance standards, 
state-of-the-art manufacturing and assembly equipment and processes must 
be used in order to meet the volume and time-to-market requirements.

                                      16

MAINTAIN TECHNOLOGICAL LEADERSHIP IN MEMORY MODULE DESIGN

    The Tanisys Group believes it is a leader in the design of both 
application specific and standard memory modules.  Through its experience 
with substantially all types of memory devices supplied by a wide range of 
leading semiconductor manufacturers, the Tanisys Group has developed 
significant expertise in memory module design and component selection.  
Its extensive library of product designs and layouts of memory modules are 
used to increase speed and efficiency in introducing new products, 
assisting its OEM customers in achieving time-to-market advantages.  The 
Tanisys Group's strategy is to apply its design expertise to continue to 
develop new memory modules that address emerging opportunities utilizing 
DRAM, SyncDRAM, SRAM and Flash technologies.  In addition, a substantial 
base of proprietary testing routines and parameters has been developed, 
which enables the diagnosing of problems in system design or memory 
components, in order to characterize the performance of new products and 
to provide high quality products in volume.

    The transition to SyncDRAM should allow the Tanisys Group to continue 
to differentiate itself from the competition through its advanced design 
capabilities at higher processor speeds.  This transition will necessitate 
a large number of new designs and the development of new memory test 
equipment as well as replacement of older existing test equipment.

INTRODUCE NEXT GENERATION MEMORY TEST EQUIPMENT

    The continuing development of new memory technologies and changing 
functionality will create the demand for next generation testing equipment 
and capabilities.  The Tanisys Group believes it is well positioned 
through the DarkHorse memory test products to take advantage of these 
changes and market expansion.  The transition to SyncDRAM will necessitate 
the development of new test programs and the replacement of existing test 
equipment.

EXPAND OEM RELATIONSHIPS AND DISTRIBUTION CHANNELS

    The Tanisys Group's experienced applications engineers continually 
work with OEMs to seek and support multiple design opportunities over 
numerous product generations.  The Tanisys Group plans to continue to 
develop relationships with its existing OEM customers and to establish 
relationships with new OEM customers both domestically and 
internationally.  The Tanisys Group is growing its sales force to address 
new opportunities with OEM customers and corporate end users worldwide.  
The Tanisys Group also plans to broaden its distribution channels by 
focusing additional marketing and sales resources on the computer reseller 
channel and establishing worldwide recognition of the Tanisys brand name.

EXPAND INTERNATIONAL SALES AND MARKETING

    The Tanisys Group is expanding its sales and marketing efforts 
internationally with an objective of establishing worldwide recognition of 
its products and the Tanisys, 1st Tech and DarkHorse brand names.

                                      17

RESEARCH AND DEVELOPMENT

    Tanisys Group management believes that the timely development of new 
products and technologies is essential to maintain the Tanisys Group's 
competitive position.  In the electronics market, the Tanisys Group'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 Tanisys Group provides research and development services 
for customers either as joint or contracted development.  The Tanisys 
Group 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.

    Tanisys Group 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 major OEMs.  Support continues to be provided to OEMs in 
the personal computer and appliance industries toward this end.  However, 
it is not anticipated that significant additional research and development 
efforts will be required for this technology.

    The Tanisys Group's research and development expenses in fiscal years 
1996, 1995 and 1994, on a pro forma basis, were $1,511,000, $804,000 and 
$683,000, respectively.

COMPETITION

    The Tanisys Group is a technology solutions company with broad 
industry product and service lines and believes that while it faces 
different competitors in its three product and service lines, there is no 
one company capable of competing in all product and service lines.  
Competition in some products, such as 1st Tech's memory manufacturing, is 
intense due to the large number of competitors with substantially greater 
financial, marketing, technical, distribution and other resources.  
However, the DarkHorse and Tanisys Touch lines are characterized by 
limited effective competition in the segments of the markets targeted by 
the Tanisys Group and its patented technology.

    The basic competitive strategy of the Tanisys Group is to utilize the 
high end custom engineering design, advanced manufacturing processes, 
module test solutions, targeted sales and marketing and advanced 
warehousing and distribution capabilities to deliver advanced 
technologies, solutions and services packaged in such a way that a 
customer is not required to deal with a substantial number of vendors but 
can look solely to the Tanisys Group to satisfy all of its needs.  The 
Tanisys Group will continue to target customers with which a long-term, 
primary or sole source relationship can be established in order to provide 
broad-based solutions to any technological or manufacturing needs.

    The competitors in the 1st Tech product line include module 
manufacturers such as SMART Modular Technologies, Micron Electronics and 
Celestica, Inc. Additional competition comes from certain suppliers who 
may have the ability to manufacture competitive products at lower costs as 
a result of their higher levels of integration.  In addition, some current 
and prospective customers may currently or in the future manufacture 
internally.

                                      18
<PAGE>

    In the memory testing industry, the DarkHorse line competes primarily 
with Terradyne, Megatest and Realm, although they provide only generic 
test equipment requiring the user to custom program the equipment for each 
specific application.  The DarkHorse test systems are pre-programmed with 
an extensive set of algorithms and test programs that are accessed through 
an intuitive user interface.

               The Tanisys Group believes that its competition in the 
capacitive touch market is limited to a few companies that are pursuing 
limited applications of their technology as opposed to the broader market 
it has targeted.

INTELLECTUAL PROPERTY

    The Company has filed four applications with the U.S. Patent and 
Trademark Office for patents to protect its intellectual property rights 
for products and technology that have been sold, licensed or are under 
development, as follows:

    1.   Application covering claims for hardware, firmware, software and
         methods operations for a broad range of applications for its touch
         technology.  The patent was granted on April 16, 1996 under
         Registration No. 5,508,700.  Corresponding international patent
         applications have been filed in selected European, Asian and North
         American countries.  Management of the Company believes that if
         competitors decide to pursue the discrete touch market, they could be
         in violation of the Company's patent.  The Company has no knowledge of
         any such infringement to date.

    2.   Application for "Keyboard Command Operation for Computer System." 
         This pending application is targeted to protect the Company's
         technology that associates multiple commands with different keyswitch
         actuations and that is applicable for computer keyboards.

    3.   Application for "Computer Input Device for Use in Conjunction with a
         Mouse Input Device."  This pending application is targeted to protect
         the Company's technology related to capacitive sensing used in a mouse
         pad or other flush-mounted touch device.

    4.   Application for "Capacitive Sensitive Input Circuit with Common Pad." 
         This pending application is targeted to protect the Company's touch
         technology which could be used in extreme or hostile environments and
         can function to improve the reliability of touch sensor operation in
         such environments.

    There can be no assurance that these pending patent applications will be 
approved or approved in the form requested.  The Tanisys Group expects to 
continue to file patent applications where appropriate to protect its 
proprietary technologies; however, the Tanisys Group believes that its 
continued success depends primarily on factors such as the technological 
skills and innovation of its personnel rather than on patent protection.  In 
addition, the Tanisys Group attempts to protect its intellectual property 
rights through trade secrets 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 Tanisys Group's trade 
secrets or other proprietary information, that disputes with respect to the 
ownership of its intellectual property rights will not 

                                      19

arise, that the Tanisys Group'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 Tanisys Group's products or 
design around the patents owned by the Tanisys Group or that third parties 
will not assert intellectual property infringement claims against the 
Tanisys Group.  In addition, there can be no assurance that foreign 
intellectual property laws will adequately protect the Tanisys Group's 
intellectual property rights abroad.  The failure of the Tanisys Group to 
protect its proprietary rights could have a material adverse effect on its 
business, financial condition and results of operations.

ENVIRONMENTAL REGULATION

    The Tanisys Group'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 Tanisys Group 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.

EMPLOYEES

    At October 31, 1996, the Tanisys Group had 113 full-time and 2 part-time
employees.

(1)      As of September 30, 1994, the Company determined that it would not 
         utilize in its current or future product line certain technology 
         purchased in 1993. Therefore, the remaining goodwill of $198,739 
         associated with this purchase was charged to expense in the period 
         ended September 30, 1994.

(2)      On May 20, 1996, the Company acquired 1st Tech and DarkHorse as a 
         result of which 1st Tech and DarkHorse became wholly owned 
         subsidiaries of the Company in exchange for the issuance of an 
         aggregate of 4,150,000 shares of Common Stock.  The acquisitions were 
         accounted for using the purchase method of accounting.  Under the 
         purchase method, the excess of purchase price over the estimated fair 
         value of the net assets acquired ($10,656,998) is classified as 
         goodwill and amortized against earnings over a two-year period.  The 
         amount of goodwill amortized for the fiscal year ended September 30, 
         1996 was $2,220,208.  The results of operations of 1st Tech and 
         DarkHorse have been included in the consolidated financial statements 
         since the date of the acquisitions.


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

OVERVIEW

    The Company was organized under the laws of the Province of British 
Columbia, Canada, on January 27, 1984, as Montebello Resources Ltd., and 
operated unsuccessfully as an oil and gas exploration company in British 
Columbia and Manitoba, Canada.  In October 1992, the Company changed its 
name to First American Capital Group Inc.  The Company then deemed 
itself inactive pursuant to the rules and regulations of the VSE, where 
its 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.  The Company changed its name to 
Rosetta Technologies Inc. in May 1993 and to Tanisys Technology, Inc. in 
July 1994.  Until May 20, 1996, the Company focused on research and 
development of highly specialized applications of capacitive touch 
sensing technology.

    Effective May 20, 1996, the Company acquired, through mergers with 
its wholly owned subsidiaries,all of the outstanding common stock of 1st 
Tech and DarkHorse and began operations in Austin, Texas as a 
consolidated group of companies in the technology industry.  In 
consideration for the acquisitions of 1st Tech and DarkHorse, the 
Company issued 2,950,000 and 1,200,000 shares, respectively, of Common 
Stock.  Prior but subject to the consummation of the acquisitions of 1st 
Tech and DarkHorse by the Company, 1st Tech issued 1,150,000 shares of 
its common stock for $2.00 per share in an equity financing, raising a 
total of $2.3 million, the proceeds of which were used to reduce 
short-term debt and provide working capital for 1st Tech.

    The Tanisys Group's net sales and gross profit increased dramatically 
over the last three fiscal years and especially in the last fiscal year due 
to the acquisitions of 1st Tech and DarkHorse.  In fiscal 1996, revenues were 
$15.0 million with gross profit of $2.3 million (15.5% of revenue) versus 
fiscal 1995 revenues of $.4 million and gross profit of $.2 million (69.4% of 
revenue). This is an increase of revenues of $14.6 million, in excess of 
4,000%, and in gross profit of $2.1 million, more than 800%.  On a pro forma 
basis (presented as though the acquisitions had taken place at the beginning 
of fiscal 1995), the fiscal 1996 revenues and gross profit were $67.952 
million and $5.138 million, respectively, versus fiscal 1995 revenue of 
$106.668 million and gross profit of $7 million.  This is a decrease in 
revenues of $38.716 million, or 36%, and a decrease in gross profit of $1.976 
million, or 28%, while gross margin increased by approximately 13.5%.  The 
decrease in revenues and corresponding decrease in gross profit was caused 

                                      22
<PAGE>

primarily by the drastic decline in the price of memory chips, 
the major material cost in the manufacture of memory modules, and the 
lack of adequate capital to buy inventory in sufficient quantities to 
obtain the favorable pricing required in competitive bidding situations 
dealing with commodity products.  While the price of the memory chip has 
currently stabilized and the acquisitions of DarkHorse and 1st Tech by 
the Company in May 1996 has infused the required capital into the 
business, management believes that revenues and gross profits will 
continue to fluctuate due to the foregoing and other factors, including, 
changes in pricing by suppliers and competitors and changes in the 
proportion of contract manufacturing done--where the customer consigns 
the material--versus manufacturing on a turnkey basis--where the Tanisys 
Group purchases the necessary materials.

NET SALES 

    On the historical accounting basis, net sales consist of software 
sales, less returns and discounts, and design engineering fees from 1994 
to May 20, 1996, the date of the acquisitions of 1st Tech and DarkHorse. 
 After the May 20, 1996 acquisitions, net sales consist of custom 
manufacturing services, custom memory modules, standard memory modules, 
design engineering fees, memory module test solutions, advanced 
technology services and computer software, less returns and discounts.  
Net sales increased from $114 thousand in fiscal 1994 to $359 thousand 
in fiscal 1995, a 215% increase, and to $14.989 million in fiscal 1996, 
a 4,075% increase.  The increase in sales in fiscal 1995 from fiscal 
1994 was due primarily to new software products and additional 
distributors.  The increase in fiscal 1996 is due to the acquisitions of 
1st Tech and DarkHorse.

    On a pro forma basis, net sales increased from $42.708 million in 
fiscal 1994 to $106.668 million in fiscal 1995, a 149.76% increase, and 
decreased to $67.952 million in fiscal 1996, a 36.3% decrease.  The 
increase from fiscal 1994 to fiscal 1995 was due primarily to the steady 
increase in the volume of sales of manufactured and purchased memory 
modules, test equipment sales, manufacturing services and the addition 
of significant new customers.  The decrease of sales in fiscal 1996 
resulted from the drastic decline in memory prices (the cost of a 4-meg 
DRAM fell from approximately  $11.25 in January of 1996 to approximately 
$1.90 in September of 1996, a decrease of $9.35, or about 83%) and the 
inability to obtain memory product and components during this extremely 
competitive period due to the lack of available capital.

GROSS PROFIT

    Cost of sales includes the costs of all components and materials 
purchased for the manufacture of products and the direct labor and 
overhead costs associated with manufacturing.  On the historical 
accounting basis, gross profit increased from $80 thousand in 1994 to 
$249 thousand in fiscal 1995, a 211% increase, to $2.328 million in 
fiscal 1996, an 835% increase.  Gross profit margin declined from 70% in 
fiscal 1994 to 69% in fiscal 1995 to 16% in fiscal 1996.  The profit 
margins in fiscal 1994 and 1995 were primarily attributable to the sale 
of software developed in conjunction with research and development on 
the capacitive touch technology, which had very little cost of sales 
associated with that development.  The gross profit margin in fiscal 
1996 is primarily from the manufacturing operation subsequent to the 
acquisitions and is discussed in the next paragraph.

    On a pro forma basis, gross profit increased from $3.411 million in 
fiscal 1994 to $7.114 million in fiscal 1995, a 108.56% increase, and 
decreased to $5.138 million in fiscal 1996, a decrease of 27.8%.  Gross 
profit margin declined from 7.99% in fiscal 1994 to 6.67% in fiscal 1995 
and increased to 7.56% in fiscal 1996.  The Company consistently made 
strategic purchasing and pricing decisions during the three-year period 
that sacrificed gross profit percentage to establish relationships with 
customers and vendors.  This practice was the primary cause of the 
steady deterioration of gross profit margin through fiscal 1995.  In 
fiscal 1996, gross profit improved slightly due to the additional 
capital made available by the Company's acquisition of 1st Tech and the 
addition of a consignment inventory of certain memory components, 
shortening the manufacturing response time and making it possible to 
compete on the basis of delivery rather than on price alone.

RESEARCH AND DEVELOPMENT

    Research and development expenses consist of the costs associated 
with the design and testing of new technologies and products.  These 
costs relate primarily to the costs of materials, personnel, management 
and employee compensation and engineering design consulting fees.  On 
the historical accounting basis, research and development increased from 
$409 thousand in fiscal 1994 to $410 thousand in fiscal 1995 and to 
$1.080 million in fiscal 1996, a 163% increase.  The increases in fiscal 
1994 though 1995 were associated with development of the capacitive 
touch technology, and the substantial increase in fiscal 1996 was due to 
the acquisitions of 1st Tech and DarkHorse.

    On a pro forma basis, research and development expenses increased 
from $683 thousand in fiscal 1994 to $804 thousand in fiscal 1995, an 
18% increase, and to $1.511 million in fiscal 1996, an 87.9% increase.  
The steady growth of research and development expense reflects the 
commitment to continuing development of new products, including module 
products, testing equipment, advanced technology and computer software.

SALES AND MARKETING

    Sales and marketing expenses include all compensation of employees 
and independent sales personnel, as well as the costs of advertising, 
promotions, trade shows, travel, direct support and overhead.  On the 
historical accounting basis, sales and marketing expenses increased from 
$394 thousand in fiscal 1994 to $1.358 million in fiscal 1995, a 245% 
increase, and decreased to $1.177 million in fiscal 1996, a 

                                      25
<PAGE>

13% decrease.  In fiscal years 1994, 1995 and 1996, sales and marketing 
expenses expressed as a percent of revenues were 346%, 378% and 8%, 
respectively.  The increase from fiscal 1994 to fiscal 1995 was connected 
with the effort to establish markets for the software products developed by 
the Company.  The decrease in 1996, after the acquisitions of 1st Tech and 
DarkHorse, reflects the decrease in commission expenses due to the decrease 
in sales revenue discussed under the paragraph heading "Net Sales" above.

    On a pro forma basis, sales and marketing expenses increased from 
$1.693 million in fiscal 1994 to $3.608 million in fiscal 1995, a 113% 
increase, and decreased to $2.828 million in fiscal 1996, a 21.6% 
decrease.  The increase from fiscal 1994 to fiscal 1995 was due 
primarily to increased commissions paid on the higher sales volumes, 
increased numbers of sales and marketing personnel and the increase in 
trade shows and other forms of product and corporate image advertising.  
The decrease in fiscal year 1996 reflects the decrease in commission 
expenses due to the decrease in sales revenue discussed under the 
paragraph heading "Net Sales" above.  In fiscal years 1994, 1995 and 
1996, sales and marketing expenses expressed as a percent of revenues 
were 3.96%, 3.38% and 4.16%, respectively.  Sales and marketing expenses 
are expected to remain approximately the same or to grow slightly when 
expressed as a percentage of revenue and to continue to increase 
significantly in terms of absolute dollars in future periods as revenues 
continue to grow. 

GENERAL AND ADMINISTRATIVE

    General and administrative costs consist primarily of personnel 
costs, including all compensation and employee benefits, and support 
costs including utilities, insurance, professional fees and all costs 
associated with a reporting company.  On the historical accounting 
basis, general and administrative expenses decreased from $1.089 million 
in fiscal 1994 to $984 thousand in fiscal 1995, a 10% decrease, and 
increased to $4.451 million in fiscal 1996, a 352% increase.  The 
decrease in fiscal 1995 from fiscal 1994 reflects the implementation of 
cost saving measures designed to make general and administrative 
expenditures more effective.  The increase in fiscal 1996 is due to the 
acquisitions of 1st Tech and DarkHorse.

    On a pro forma basis, general and administrative expenses increased 
from $2.569 million in fiscal 1994 to $4.025 million in fiscal 1995, a 
57% increase, and increased to $4.541 million in fiscal 1996, a 12.82% 
increase.  Expressed as a percentage of net sales, general and 
administrative expenses were 6%, 4% and 7% in fiscal years 1994, 1995 
and 1996, respectively.  The increase in expenses in each year was 
caused primarily by an increase in personnel to support the Tanisys 
Group's increasing business activity.  The absolute dollar expenses 
associated with the general and administrative area are expected to 
increase significantly in future periods due to anticipated continued 
growth in business activity and increased costs associated with being a 
reporting company.  The general and administrative expenses are not 
expected to grow significantly in future periods when expressed as a 
percentage of sales.

UNUSUAL CHARGE

    On the historical accounting basis, other income (expense) increased 
from $39 thousand in fiscal 1994 to $59 thousand in fiscal 1995, a 51.3% 
increase, and decreased to -$30 thousand in fiscal 1996, a 151.0% 
decrease.  On a pro forma basis, other income (expense) increased from 
- - -$244 thousand in fiscal 1994 to -$517 thousand in fiscal 1995, a 111.9% 
increase, and decreased to -$294 thousand in fiscal 1996, a

                                      26
<PAGE>

43.1% decrease.  The expense shown in fiscal 1994 relates to the recognition 
by the Company that the computer game controller technology acquired in 1993 
would not be utilized in the Company's current or future operations.  
Therefore, the remaining $199 thousand of goodwill associated with that 
purchase was charged as an unusual charge in fiscal 1994. No other goodwill 
chargeoffs are currently expected except through amortization charges over 
the useful life of the respective assets.

OTHER INCOME (EXPENSE), NET

    Other income (expense), net consists primarily of interest income 
less interest expense.  Interest expense is attributable to borrowings 
from a bank credit line.  Substantially all of the interest expense in 
the three-year pro forma period relates to credit line draws made for 
short-term inventory requirements and to fund accounts receivable.  
Interest income relates to investment of available cash in short-term 
interest bearing accounts and cash equivalent securities.  The Company 
had limited amounts of available cash until its May 20, 1996 
acquisitions of 1st Tech and DarkHorse, and, therefore, all fiscal years 
reflect net interest expense.  The Tanisys Group expects to continue to 
require borrowings to fund growth in inventories and accounts receivable 
in the future and therefore expects to continue to reflect net interest 
expense.

PROVISION FOR INCOME TAXES

    The Company has never paid income taxes and at September 30, 1996 
had a net operating loss carryover of $989 thousand.  While there can be 
no assurance that the Tanisys Group will generate the taxable income 
required to use all or any part of the carryover prior to the expiration 
of the carryover, the Tanisys Group would be able to incur taxable 
income in the carryover period equal to the total loss carryover without 
the payment of taxes.  The existing carryover expires 15 years after the 
year in which it was incurred.  Therefore, if the carryover is not used 
to offset future taxable income, the $1.785 million net operating loss 
carryforward at September 30, 1996 will expire in fiscal years 2007 
through 2011.

LIQUIDITY AND CAPITAL RESOURCES

    During the five fiscal years presented in this analysis, until the 
May 20, 1996 acquisitions of 1st Tech and DarkHorse, the Company 
primarily utilized funds generated by equity financings of its Common 
Stock and the exercise of warrants issued in certain of those equity 
financings to generate the funds required to fund its research and 
development activities, acquire capital equipment and pay its general 
and administrative expenses.

    Since inception and until the May 20, 1996 acquisitions by the 
Company, 1st Tech and DarkHorse used funds generated from operations, an 
equity financing, capital leases, vendor credit and certain bank 
borrowings to support their respective operations, acquire capital 
equipment and finance inventory acquisitions and accounts receivable 
balances.

    Subsequent to the May 20, 1996 acquisitions, the Tanisys Group has 
utilized the funds acquired in equity financings of its Common Stock and 
the exercise of warrants issued in equity financings of its Common 
Stock, capital leases, vendor credit, certain bank borrowings and funds 
generated from operations to support its operations, carry on research 
and development activities, acquire capital equipment, finance 

                                      27
<PAGE>

inventories, finance accounts receivable balances and pay its general 
and administrative expenses.  At September 30, 1996, the Tanisys Group 
had $2.690 million of cash and $2.809 million of working capital.

    The Tanisys Group has a $6 million revolving line of credit with The 
Chase Manhattan Bank, which is secured by its accounts receivable and 
inventories. This line of credit matures June 30, 1998.  Amounts 
available for borrowing are limited to the lower of the commitment 
amount or a borrowing base amount calculated based on certain levels of 
accounts receivable.  At September 30, 1996, $3.075 million was 
outstanding and $2.925 million was available under the line of credit.  
The line of credit has certain restrictions concerning, among other 
things, the payment of dividends, additional debt and material changes 
in management and requires the Tanisys Group to maintain certain minimum 
financial ratios including a minimum net worth and minimum current ratio.

    Capital expenditures totaled approximately $523,000, $815,000 and 
$852,000 in fiscal years 1994, 1995 and 1996, respectively.  These 
expenditures were primarily for the purchase of manufacturing equipment, 
test equipment and the expansion of manufacturing facilities.  The 
Tanisys Group plans to spend approximately $3 million in fiscal 1997 in 
capital expenditures for additional manufacturing capacity.

    The Tanisys Group has entered into certain capital lease 
arrangements.  The outstanding principal on these obligations at 
September 30, 1996 was $171 thousand.  See Note 6 to the Company's 
Consolidated Financial Statements.

    The Tanisys Group believes that its existing funds, anticipated cash 
flow from operations and amounts available from future vendor credit, 
bank borrowings, the exercise of warrants issued in prior equity 
financings, and equity financings will be sufficient to meet its working 
capital and capital expenditure needs for the next twelve months.

ITEM 3.        PROPERTIES.

    At September 30, 1996, the Company and its wholly owned 
subsidiaries, 1st Tech and DarkHorse, leased and occupied approximately 
33,000 square feet of space for their production facility and corporate 
and administrative offices at 12201 Technology Boulevard, Suite 130, 
Austin, Texas, pursuant to a lease which expires on April 30, 1998.  The 
lease has certain expansion options, renewal options and rights of first 
refusal.  The Company currently is paying annual rental of $184,118, 
plus a pro rata charge for property taxes, common area maintenance and 
insurance.  The Company believes that its current facilities are 
adequate to meet its current needs.

EMPLOYEE BENEFIT PLANS

401(K) RETIREMENT PLAN

     On May 20, 1996, the effective date of the Company's acquisition of 1st 
Tech, the Company adopted the 1st Tech 401(k) Plan (the "401(k) Plan").  
Participation in the 401(k) Plan is offered to eligible employees of the 
Tanisys Group (collectively, the "Participants").  Generally, all employees 
of the Tanisys Group who are 21 years of age and who have completed one year 
of service during which they worked at least 1,000 hours are eligible for 
participation in the 401(k) Plan.

     The 401(k) Plan is a form of defined contribution plan that provides 
that Participants generally may make voluntary salary deferral contributions, 
on a pre-tax basis, of between 1% and 15% of their base compensation in the 
form of voluntary payroll deductions up to a maximum amount as indexed for 
cost-of-living adjustments ("Voluntary Contributions").  Since its adoption 
of the 401(k) Plan, the Company has not made any matching contributions, but 
may elect in the future to make matching contributions of up to 100% of the 
first 6% of a Participant's compensation contributed as salary deferral.

STOCK OPTION PLAN

     ADMINISTRATION OF THE PLAN.  The Company's 1993 Stock Option Plan (as 
thereafter amended, the "Option Plan") is administered by a committee (the 
"Stock Option Committee") of three members of the Board of Directors.  The 
Stock Option Committee currently consists of three non-employee members of 
the Board of Directors, Parris H. Holmes, Jr., James E. Sowell and Theodore 
W. Van Duyn.  The Option Plan grants broad authority to the Stock Option 
Committee to grant options to key employees, directors and consultants 
selected by the Stock Option Committee; to determine the number of shares 
subject to options; the exercise or purchase price per share, subject to VSE 
requirements; the appropriate periods and methods of exercise and 
requirements regarding the vesting of options; whether each option granted 
shall be an incentive stock option ("ISO") or a non-qualified stock option 
("NQSO") and whether restrictions such as repurchase options are to be 
imposed on shares subject to options and the nature of such restrictions, if 
any.  In making such determinations, the Stock Option Committee may take into 
account the nature and period of service of eligible participants, their 
level of compensation, their past, present and potential contributions to the 
Company and such other factors as the Stock Option Committee in its 
discretion deems relevant.

     The Option Plan further directs the Stock Option Committee to set forth 
provisions in option agreements regarding the exercise and expiration of 
options according to stated criteria.  The Stock Option Committee oversees 
the methods of exercise of options, with attention being given to compliance 
with appropriate securities laws and regulations.

     The options have certain anti-dilution provisions and are not assignable 
or transferable, other than by will or by the laws of descent and 
distribution or pursuant to a qualified domestic relations order.  During the 
lifetime of an optionee, the options granted under the Option Plan are 
exercisable only by the optionee or his or her guardian or legal 
representative.  The Company or its subsidiaries may not make or guarantee 
loans to individuals to finance the exercise of options under the Option 
Plan.  The duration of options granted under the Option Plan cannot exceed 
ten years (five years with respect to a holder of 10% or more of the 
Company's shares in the case of an ISO).

     GENERAL.  The Option Plan was approved by the Company's stockholders on 
March 31, 1994 and adopted by the Board of Directors on October 25, 1993.  
The purposes of the Option Plan are to advance the best interests of the 
Tanisys Group by providing its employees, directors and consultants who have 
substantial responsibility for the Tanisys Group's management, success and 
growth, with additional incentive and to increase their proprietary interest 
in the success of the Tansiys Group, thereby encouraging them to remain in 
the Tanisys Group's employ or service.

     The Option Plan provides for the grant of ISOs, under Section 422 of the 
Internal Revenue Code of 1986, as amended (the "Code"), and stock options 
that do not qualify under Section 422 of the Code ("NQSOs").  The option 
price for ISOs may not be less than 100% of the fair market value of the 
Common Stock on the date of grant, or 100% of fair market value with respect 
to any ISO issued to a holder of 10% or more of the Company's shares.  The 
exercise price of NQSOs also is limited to the fair market value of the 
Common Stock on the date of grant.  Common Stock issued under the Option Plan 
may be newly issued or treasury shares.  The Option Plan does not permit the 
use of already owned


                                        38
<PAGE>


Common Stock as payment for the exercise price of options.  If any option 
granted under the Option Plan terminates, expires or is surrendered, new 
options may thereafter be granted covering such shares.

     Under the terms of the Option Plan 2,600,000 shares of Common Stock have 
been reserved for the granting of options.  At October 31, 1996, options to 
purchase 2,187,100 shares had been granted under the Option Plan, leaving 
412,900 shares available for future grants under the Option Plan.  In 
addition, at October 31, 1995, options to purchase 155,000 shares 
("compensation contract options") had been granted outside the Option Plan, 
prior to its adoption.

     AMENDMENT AND TERMINATION OF THE OPTION PLAN.  The Option Plan 
terminates on October 24, 2003.  The Stock Option Committee is authorized to 
amend or terminate the Option Plan at any time, except that it is not 
authorized without stockholder approval (except with regard to adjustments 
resulting from changes in capitalization) to (i) increase the aggregate 
number of shares which may be issued under options pursuant to the provisions 
of the Option Plan; (ii) reduce the option price at which an ISO may be 
granted to an amount less than the fair market value per share at the time 
such option is granted; (iii) change the class of employees eligible to 
receive options; (iv) materially modify the requirements as to affiliate 
eligibility for participation in the Option Plan; (v) materially increase the 
benefits accruing to participants under the Option Plan; or (vi) effect an 
amendment that would cause ISOs issued pursuant to the Option Plan to fail to 
meet the requirements of "incentive stock options" as defined in Section 422 
of the Code, provided, however, that the Stock Option Committee shall have 
the power to make such changes in the Option Plan and in the regulations and 
administrative provisions thereunder or in any outstanding option as in the 
opinion of counsel for the Company may be necessary or appropriate from time 
to time to enable any ISOs granted pursuant to the Plan to continue to 
qualify as "incentive stock options" under the Code and the regulations which 
may be issued thereunder as in existence from time to time.

     On May 20, 1996, 1st Tech purchased a Quad QSP-2 High Speed Fine Pitch 
Surface Mount Assembly System from Gary Pankonien for $200,000 in an 
arms-length, negotiated transaction.  Previously, this equipment had been

1st Tech, the Tanisys Group has paid $10,000 to 1st Tech Molding, Inc., a 
non-affiliated, private company owned 45% by Mr. Pankonien, payment for

was $6.10 per share.  At November 22, 1996, there were 234 registered holders 
of record of the Common Stock, and the number of beneficial holders was

DIVIDENDS

     To date, the Company has not declared or paid any dividends with respect 
to the Common Stock, and the current policy of the Board of Directors is to 
retain earnings, if any, to provide for the growth of the Company's business. 
 Consequently, no cash dividends are expected to be paid on the Common Stock 
in the foreseeable future. Further, there can be no assurance that the 
proposed operations of the Company will generate the revenue and cash flow 
needed to declare a cash dividend or that the Company will have legally 
available funds to pay dividends at any time in the future.  In addition, the 
Company's bank borrowings prohibit the payment of cash dividends.

ITEM 10.  RECENT SALES OF UNREGISTERED SECURITIES.

     The transactions set forth below were deemed exempt from registration 
under the Securities Act of 1933, as amended (the "Securities Act"), by 
reason of Section 4(2) of the Securities Act.  In connection with each of 
these transactions, the shares were sold to a limited number of persons, all 
of whom were accredited investors as defined by Item 501 of Regulation D of 
the Securities and Exchange Commission (the "Commission"), such persons were 
provided access to all relevant information regarding the Company and/or 
represented to the Company that they were "sophisticated" investors, and such 
persons represented to the Company that the shares were purchased for 
investment purposes only and with no view to distribution.  Restrictive 
legends were placed on all stock certificates.

     On August 24, 1994, the Company sold an aggregate of 1,500,000 shares of 
Common Stock to 13 accredited investors for cash at an offering price of 
$1.00 per share.  These purchasers also received nontransferable Class A

1,500,000 shares of Common Stock. Each Class A Warrant entitled the holder 
thereof to purchase, at any time until August 31, 1995, one share of Common 
Stock at an exercise price of $1.00, subject to adjustment.  If the Class A 
Warrants were not exercised during such period, each Class A Warrant entitled 
the holder thereof to purchase, at any time from September 1, 1995 until 
August 31, 1996, one share of Common Stock at an exercise price of $1.25, 
subject to adjustment.  All of the Class A Warrants were exercised prior to 
their expiration date of August 31, 1996.

                                        43
<PAGE>


entitled the holder thereof to purchase, at any time until May 8, 1996, one 
share of Common Stock at an exercise price of $2.00, subject to adjustment.  
If the Class B Warrants were not exercised during such period, each Class B 
Warrant entitles the holder thereof to purchase, at any time from May 9, 1996 
until May 8, 1997, one share of Common Stock at an exercise price of $2.30, 
subject to adjustment.  Following May 8, 1997, the Class B Warrants will no 
longer be exercisable and will have no value.  At October 31, 1996, Class B 
Warrants have been exercised for the purchase an aggregate of 15,000 shares 
of Common Stock.

     In October 1995, a warrant granting the right to acquire 34,000 shares 
of Common Stock for a period of two years was issued to an unaffiliated party 
as payment for legal services rendered.  The warrant entitled the holder to 
purchase, at any time until October 12, 1996, one share of Common Stock at an 
exercise price of $2.00 per share, subject to adjustment, and if not 
exercised during such period, entitles the holder to purchase at any time 
until October 13, 1997, one share of Common Stock at an exercise price of 
$2.25 per share, subject to adjustment.  Following October 13, 1997, this 
warrant will no longer be exercisable and will have no value.  At October 31, 
1996, the warrant had not been exercised.

     In December 1995, the Company sold an aggregate of 941,177 shares of 
Common Stock to 11 accredited investors for cash at an offering price of 
$1.70 per share.  The purchasers also received nontransferable Class C Stock 
Purchase Warrants (the "Class C Warrants").  Each Class C Warrant entitles 
the holder to purchase, at any time until December 20, 1996, one share of 
Common Stock at an exercise price of $1.70 per share, subject to adjustment.  
If the Class C Warrants have not been exercised during such period, each 
Class C Warrant entitles the holder to purchase, at any time from December 
21, 1996 until December 20, 1997, one share of Common Stock at an exercise 
price of $1.95 per share, subject to adjustment.  Following December 20, 
1997, the Class C Warrants will no longer be exercisable and will have no 
value.  At October 31, 1996, no Class C Warrants have been exercised.

COMMON STOCK

     Holders of Common Stock are entitled to receive dividends when, as and 
if declared by the Board of Directors from funds legally available therefor.  
See "Item 9.  Market Price of and Dividends on the Registrant's Common Equity 
and Related Stockholder Matters - Dividend Policy."  Each share of Common 
Stock entitles the holder thereof to one vote upon matters voted upon by the 
stockholders.  Cumulative voting for the election of directors is not 
permitted, which means that the holders of a majority of shares voting for 
the election of directors can elect all members of each class of the Board of 
Directors.  Except as otherwise required by applicable Wyoming law, a 
majority vote is sufficient for any action that requires the vote or 
concurrence of stockholders, except that a plurality vote is sufficient to 
elect directors.

     The holders of Common Stock do not have any preemptive, subscription, 
redemption or conversion rights or privileges.  Upon liquidation or 
dissolution of the Company, the holders of Common Stock are entitled to share 
ratably in the net assets of the Company remaining after payment of 
liabilities and liquidation preferences of any outstanding shares of 
Preferred Stock.  All shares of Common Stock now outstanding are fully paid 
and non-assessable.

PREFERRED STOCK

     The Preferred Stock may be issued from time to time by the Board of 
Directors in one or more series, without further stockholder approval or 
action, with such designations, powers, limitations, restrictions, 
qualification, rights, preferences and privileges as the Board of Directors 
may determine.

WARRANTS

     The Company currently has outstanding three series of Warrants to 
purchase Common Stock.  The Class B and Class C Warrants were issued to 
investors purchasing shares of Common Stock in equity financings closed

a warrant was issued in October 1995 to an unaffiliated party in payment of 
legal fees.  The Class B Warrants, the October 1995 warrant and the Class C 
Warrants are referred to herein as the "Warrants."

     CLASS B WARRANTS.  A total of 900,000 Class B Warrants were issued in 
May 1995 in connection with the Company's $1,800,000 equity financing.  Each 
Class B Warrant entitled the holder thereof to purchase, at any time until 
May 8, 1996, one share of Common Stock at an exercise price of $2.00 per 
share, subject to adjustment.  Class B Warrants not exercised as of May 8, 
1996 entitle the holders thereof to purchase, at any time from May 9, 1996

Warrants have been exercised for the purchase of 15,000 shares of Common 
Stock at $2.00 per share.

     OCTOBER 1995 WARRANT.  In October 1995, a warrant granting the right to 
acquire 34,000 shares of Common Stock for a period of two years was issued to 
an unaffiliated party in payment for legal services rendered. This warrant 
entitled the holder to purchase, at any time until October 12, 1996, one 
share of Common Stock at an exercise price of $2.00 per share, subject to 
adjustment, and if not 


                                        45
<PAGE>


exercised during such period, entitles the holder to purchase at any time 
until October 13, 1997, one share of Common Stock at an exercise price of 
$2.25 per share, subject to adjustment.  Following October 13, 1997, this 
warrant will no longer be exercisable and will have no value. At October 31, 
1996, this warrant had not been exercised.

     CLASS C WARRANTS.  A total of 941,177 Class C Warrants were issued as of 
December 1995 in connection with the Company's $1,600,000 equity financing.  
Each Class C Warrant entitles the holder thereof to purchase, at any time 
until December 20, 1996, one share of Common Stock at an exercise price of 
$1.70 per share, at any time until December 20, 1996, subject to adjustment.  
If the Warrants have not exercised, then for the period December 21, 1996 to 
December 20, 1997, each Class C Warrant entitles the holder to purchase one 
share of Common Stock at an exercise price of $1.95 per share, subject to

the Company with the Exercise Form attached to the certificate duly completed 
and executed, accompanied by payment (in the form of cash or certified or 
bank cashier's check payable to the order of the Company) of the full 
exercise price.

     The Warrants contain provisions that provide for adjustment of the 
exercise price in the event the outstanding shares of Common Stock shall be 
subdivided into a greater number of shares, a non-cash dividend in Common 
Stock shall be paid in respect of Common Stock or the outstanding shares of 
Common Stock shall be combined into a smaller number of shares thereof.

     The Company is not required to issue fractional shares, and in lieu 
thereof, will make a cash payment based upon the current estimated fair 
market value of such fractional shares.  The registered owner of a Warrant 
will not possess any rights as a stockholder of the Company unless and until 
the Warrant is exercised.  Upon the respective expiration date of the 
Warrants, they will no longer be exercisable for shares of Common Stock and 
will not have any value.

     TRANSFER AGENT.  The Company's transfer agent and registrar is Montreal 
Trust Company of Canada, Vancouver, B.C., Canada.

ITEM 12.  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


                                        46
<PAGE>


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, 
by-law, amendment, vote of stockholders or otherwise.

LIMITATION OF LIABILITY

     Article 12 of the Articles provides that no director shall be personally 
liable to the Company or any shareholder 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 shareholders, (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 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 benefited 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 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 Act and is therefore unenforceable.

CERTAIN PROVISIONS OF THE ARTICLES AND THE BYLAWS

     Certain provisions in the Articles and Bylaws and the WBCA could make 
more difficult the acquisition of the Company by means of a tender offer, a 
proxy contest or otherwise.  These provisions are expected to discourage 
certain types of coercive takeover practices and inadequate takeover bids and 
to encourage persons seeking to acquire control of the Company to first 
negotiate with the Company.  The Company believes that the benefits of 
increased protection of the Company's potential ability to negotiate with the 
proponent of an unfriendly or unsolicited proposal to acquire or restructure 
the Company outweigh the disadvantages of discouraging such proposals 
because, among other things, negotiation of such proposals could result in an 
improvement of their terms.


                                        47

     CLASSIFIED BOARD OF DIRECTORS.  The Articles and the Bylaws provide that 
the Board of Directors is divided into three classes of directors, with the 
terms of each class expiring in a different year.  The Bylaws provide that 
the number of directors will be fixed from time to time exclusively by the 
Board of Directors but shall consist of not more than 15 nor less than 3 
directors.  A majority of the Board of Directors then in office has the sole 
authority to fill any vacancies on the Board of Directors.

     PREFERRED STOCK.  The issuance of Preferred Stock may have the effect of 
delaying, deferring or preventing a change in control of the company or may 
materially affect the rights evidenced by, or amounts payable with respect 
to, the shares of Common Stock.  The voting and conversion rights of any 
class or series of Preferred Stock issued by the Company could adversely 
affect, among other things, the voting rights of existing stockholders.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF CONSOLIDATION

The consolidated financial statements include the accounts of Tanisys 
Technology, Inc. ("Tanisys") and its wholly-owned subsidiaries, 1st Tech 
Corporation ("1st Tech"), DarkHorse Systems, Inc. ("DarkHorse"), Timespan
Communications Corp. ("Timespan") and Rosetta Marketing and Sales Inc. 
(collectively, the "Company"). The Company provides custom design, engineering
and manufacturing services, test solutions and standard and custom module 
products to leading original equipment manufacturers in the computer, networking
and telecommunications industries. Numerous factors affect the Company's 
operating results, including general economic conditions, competition, changing
technologies, component shortages or price fluctuations. A change of any of 
these factors could have an adverse effect on the Company's financial position 
or results of operations. The Company has experienced losses since inception. 
The Company continues to develop additional products, and with the current year 
acquisitions (Note 2), the Company has existing salable products. The continued 
success of the Company depends upon the Company's ability to generate sufficient
sales from the development of new products or increased sales of existing 
products.

The consolidated financial statements have been prepared in accordance with 
generally accepted accounting principles in the United States which, as applied 
to these financial statements, conform in all material respects with accounting
principles generally accepted in Canada. All significant intercompany balances 
and transactions have been eliminated in consolidation.

Tanisys is a Wyoming corporation which was originally organized in British 
Columbia, Canada to pursue oil and gas exploration. Unsuccessful in the 
exploration business and dormant pursuant to the rules and regulations of the
Vancouver Stock Exchange, several investors gained control of the Company to 
raise financing and complete the acquisition of Timespan. Timespan had software
technology and patent applications which, in part, are the foundation of the 
Company's development and marketing efforts.

Tanisys changed its name from Rosetta Technologies Inc. on July 11, 1994. Prior 
to Rosetta Technologies Inc., the Company had been known as First American 
Capital Group Inc. and Montebello Resources Ltd.

Certain reclassifications of amounts related to 1994 and 1995 have been made to 
conform with the 1996 presentation.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with original maturities of 
three months or less to be classified as cash equivalents. Cash equivalents are 
carried at cost, which approximates market. The Company places its cash 
investments in high credit quality instruments.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

RECEIVABLES

The Company grants credit to domestic and international original equipment 
manufacturers, distributors and end users. The Company carries a business credit
policy covering certain accounts receivable.  The insurance policy provides
protection against losses from uncollectible accounts resulting from insolvency
of specified customers.  As of September 30, 1996, the total available coverage
under the policy was $2,050,000.

INVENTORY

Inventory is stated at the lower of cost or market.  In the third quarter of 
1996, the Company changed its method of accounting for inventories from the 
first-in, first-out (FIFO) method to a weighted average cost basis.  The change
did not have a significant effect on results of operations for 1996, nor is it 
anticipated that it will have a material effect on future periods.  Prior to the
change, the Company's inventory costs would not have differed significantly 
under the two methods. Costs include direct materials, direct labor and certain
indirect manufacturing overhead expenses.

REVENUE RECOGNITION

Revenues from direct sales and sales to resellers are recognized when the 
related products are shipped.  The Company warrants products against defects 
and has a policy concerning the return of products.

DEPRECIATION AND AMORTIZATION

The Company uses the straight-line method of depreciation.  Under the 
straight-line method of depreciation, the Company is using the following lives:

Machinery and equipment                      3-7 
Office and engineering equipment             5
Computer equipment and software              3
Furniture and fixtures                       5
Vehicles                                     5
Leasehold improvements                       Shorter of useful life or remaining
                                             term of the lease

Incorporation costs are amortized on a straight-line basis over five years. Upon
dissolution of Timespan, the Company wrote-off $747 in unamortized incorporation
costs.  Accumulated amortization at September 30, 1996, 1995 and 1994 was $512, 
$1,522 and $761, respectively.

                       FINANCIAL STATEMENTS
                SEPTEMBER 30, 1996, 1995 AND 1994
         (EXPRESSED IN U.S. DOLLARS EXCEPT AS INDICATED)
                                 
1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Patents and trademarks are amortized on a straight-line basis over 10 years. In 
fiscal 1995, the Company wrote-off $12,095 in trademark costs related to the 
registration of the name SpinWizard, since the product associated with that
trademark is no longer being sold. Accumulated amortization at September 30, 
1996, 1995 and 1994, was $10,799, $6,569 and $0, respectively.

FOREIGN CURRENCY TRANSLATION

Assets and liabilities denominated in foreign currencies are translated at the 
exchange rate at the balance sheet date. Revenues, costs, and expenses are 
translated at average rates of exchange prevailing during the year. Gains and 
losses on foreign currency transactions are included in other expenses. 
Translation adjustments resulting from this process are charged or credited to 
equity.

RESEARCH AND DEVELOPMENT

Under the criteria set forth in Statement of Financial Accounting Standards 
No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased or 
Otherwise Marketed," capitalization of software development costs begins upon 
the establishment of technological feasibility.  The ongoing assessment of the 
recoverability of these costs requires considerable judgment by management with
respect to certain external factors, including, but not limited to, anticipated
future gross product revenues, estimated economic life and changes in software 
and hardware technology. After considering the above factors, the Company has 
determined that software development costs incurred for the years ended 
September 30, 1996, 1995 and 1994 were properly expensed.

LOSS PER SHARE

Loss per share is calculated based upon the weighted average number of common 
shares outstanding during the year.

NEW ACCOUNTING PRONOUNCEMENTS

In March 1995, Statement of Financial Accounting Standards No. 121, "Accounting 
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be 
Disposed Of" (FAS 121), was issued. Under FAS 121, an impairment loss must be 
recognized, for long-lived assets and certain identifiable intangibles to be 
held and used by an entity, whenever events or changes in circumstances 
indicate that the carrying amount of an asset may not be recoverable.  FAS 121 
is effective for financial statements issued for fiscal years beginning after 
December 15, 1995, and must be adopted on a prospective basis. Restatement of 
previously issued financial statements is not permitted.  The Company adopted 
FAS 121 effective October 1, 1995. Such adoption did not have a material 
effect on the financial condition or results of operations of the Company.

                SEPTEMBER 30, 1996, 1995 AND 1994
         (EXPRESSED IN U.S. DOLLARS EXCEPT AS INDICATED)
                                 
1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

In October 1995, Statement of Financial Accounting Standards No. 123, 
"Accounting for Stock-Based Compensation" (FAS 123), was issued. FAS 123 
defines a fair value based method of accounting for employee stock options or
similar equity instruments and encourages all entities to adopt that method of 
accounting for all of their employee stock compensation plans. Under the fair 
value based method, compensation cost is measured at the grant date based on the
value of the award and is recognized over the service period of the award, which
is usually the vesting period. However, FAS 123 also allows entities to continue
to measure compensation costs for employee stock compensation plans using the 
intrinsic value method of accounting prescribed by Accounting Principles Board 
Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25). Entities 
electing to remain with the accounting prescribed by APB 25 must make pro forma
disclosures of net income and earnings per share as if the fair value based 
method recommended by FAS 123 had been applied.  The accounting requirements of 
FAS 123 are effective for transactions entered into in fiscal years that begin 
after December 15, 1995. The disclosure requirements of FAS 123 are effective
for financial statements for fiscal years beginning after December 15, 1995. The
Company intends to measure compensation costs in accordance with APB 25 and to 
provide pro forma disclosures of net income and earnings per share as if the 
fair value based method of accounting under FAS 123 had been applied. Therefore,
FAS 123 will  not have a material effect on the financial position or results 
of operations of the Company.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the financial statements and 
the reported amount of revenues and expenses during the reporting period. Actual
results could differ from those estimates.

2.   ACQUISITIONS OF 1ST TECH AND DARKHORSE

On May 20, 1996, the Company acquired 1st Tech and DarkHorse, as a result of 
which 1st Tech and DarkHorse became wholly owned subsidiaries of the Company in
exchange for 4,150,000 shares of the Company's common stock. 1st Tech is engaged
primarily in the design, manufacture and sale of standard memory products to the
memory aftermarket and custom memory assemblies to original equipment 
manufacturers, and offers engineering design and contract manufacturing 
services. DarkHorse designs and markets memory testing equipment primarily to 
electronic equipment manufacturers.

At the closing of the acquisitions, the Company granted options for the purchase
of 550,000 common shares to key employees of 1st Tech and DarkHorse, allowed 
Mr. Gary W. Pankonien, former owner of 1st Tech and one of the three former 
owners of DarkHorse, to appoint two members to the Company's seven-member Board
of Directors, and paid a consulting bonus to a Director of the Company of 
207,500 common shares at a deemed price of $3.80 per share.

10.       INCOME TAXES

The Company accounts for deferred income taxes using the liability method. 
At September 30, 1996, the Company's Canadian subsidiary, Timespan, had a 
non-capital loss carryforward of approximately CDN $127,000 which may be applied
against future taxable income. The loss carryforward results in a deferred tax 
asset of CDN $57,000 which expires in 2000. Additionally, at September 30, 1996,
Timespan had deferred tax assets of CDN $43,000 principally relating to 
unclaimed investment tax credits.

         (EXPRESSED IN U.S. DOLLARS EXCEPT AS INDICATED)


10.      INCOME TAXES (CONTINUED)

During 1996 and 1995, the Company incurred consolidated net operating losses 
for U.S. income tax purposes of approximately $1,785,000 and $2,548,000, 
respectively. The loss carryforwards expire in 2011 and 2010, respectively. 
During 1996, the Company had temporary differences resulting in future tax 
deductions of $693,000 principally representing tax basis in accrued liabilities
and intangible assets. Deferred income tax assets from the loss carryforwards 
and asset basis differences aggregate $2,240,000.

For financial reporting purposes, valuation allowances of $2,240,000 and 
$1,413,000 have been recorded to offset the deferred tax assets due to the 
uncertainty as to whether the benefits will be realized.

The availability of the net operating loss carryforward and future tax 
deductions to reduce taxable income is subject to various limitations under 
the Internal Revenue Code of 1986, as amended, (the Code) in the event of an 
ownership change as defined in Section 382 of the Code.

No federal or state taxes were due or paid in 1996 and 1995. 

11.       UNUSUAL CHARGE

At September 30, 1994, the Company determined that it would not utilize in its 
current or future products, the computer game controller technology purchased 
from Timespan. Therefore, the remaining goodwill associated with the Timespan 
acquisition of $198,739 was charged to expense as an unusual charge in the 
period ended September 30, 1994 (Note 13).

12.       EMPLOYEE BENEFITS

Effective January 1, 1995, 1st Tech sponsored an employee benefit plan 
(the Plan) which qualifies under Section 401(k) of the Internal Revenue Service
Code for eligible employees. Eligible employees may defer a portion of their
annual compensation under the Plan subject to maximum limitations. The 
requirements for eligibility include a minimum age of 21 and a minimum of one 
year of service. As of the date of acquisition of 1st Tech, all employees of
the Company joined the Plan.

Under provisions of the Plan, the Company may elect to make matching 
contributions to the Plan for the benefit of the participants. No contributions
were made in 1996.

13.       COMMITMENTS AND CONTINGENCIES

During fiscal 1993, the Company's subsidiary Timespan entered into a five year 
royalty agreement with its former principal shareholders. The agreement provides
for royalties to be paid for the use of the computer game controller technology.
The royalties are to be paid subsequent to Timespan achieving a CDN $3,000,000 
net cumulative profit from the sale of devices involving the technology. The 
royalties will be calculated as the lesser of CDN $250,000 per annum or 5% of 
the gross wholesale receipts, as defined in the agreement, from sales exceeding
the above noted amount. If the amount payable is less than CDN $250,000

in any particular year, the difference will be carried forward to the following
year to increase the maximum amount payable in that year. The Company is not 
currently using the computer game controller technology and the royalty does 
not relate to the Company's current products.  (note 11)

14.  SUBSEQUENT EVENT

In October 1996, the Company granted, subject to regulatory approval, stock 
options to key employees for the purchase of 423,000, 110,000 and 5,000 common 
shares at a per share price of $4.09, $4.17 and $4.44, respectively. These 
options are not considered outstanding until approved by the Vancouver Stock 
Exchange.

Timespan, a wholly owned subsidiary of the Company, was dissolved as of 
October 23, 1996.

                         REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS





To 1st Tech Corporation and
DarkHorse Systems, Inc.:

We have audited the accompanying combined balance sheets of 1st Tech Corporation
and DarkHorse Systems, Inc. (Texas corporations), as of December 31, 1995 and 
1994, and the related combined statements of income, shareholders' equity and 
cash flows for each of the three years in the period ended December 31, 1995. 
These financial statements are the responsibility of the Companies' management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

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

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of 1st Tech Corporation and 
DarkHorse Systems, Inc., as of December 31, 1995 and 1994, and the results of 
their operations and their cash flows for each of the three years in the period
ended December 31, 1995, in conformity with generally accepted accounting 
principles.

                 DECEMBER 31, 1995, 1994 AND 1993
                                 


1.  BASIS OF PRESENTATION AND ORGANIZATION:

The accompanying combined financial statements include the accounts of 1st 
Tech Corporation and DarkHorse Systems, Inc. (collectively referred to as the 
Companies).  The Companies' financial statements have been combined as both 
of these entities are under common ownership.  All significant intercompany 
accounts and transactions have been eliminated in combination.

1st Tech Corporation (1st Tech) is a privately held S-Corporation that was 
incorporated under the laws of the State of Texas on January 20, 1993.  1st 
Tech is engaged primarily in the design, manufacture and sale of standard 
memory products to the memory aftermarket and custom memory assemblies to 
original equipment manufacturers.  In addition, 1st Tech offers engineering 
design and contract manufacturing services.  The principal market for the 
Company's products is domestic-based original equipment manufacturers in the 
electronics industry, including personal computer manufacturers and 
telecommunications service providers.

DarkHorse Systems, Inc. (DarkHorse), is a privately held S-Corporation that 
was incorporated under the laws of the State of Texas in 1992.  DarkHorse is 
engaged in the business of designing and marketing memory testing equipment 
primarily to domestic electronic equipment manufacturers.

Effective May 20, 1996, Tanisys Technology, Inc. (Tanisys), acquired all of 
the outstanding common stock of the Companies in exchange for 4.15 million 
shares of Tanisys' common stock (Note 14).

2.  SUMMARY OF SIGNIFICANT
    ACCOUNTING POLICIES:     

REVENUE RECOGNITION

Revenue is stated net of actual and estimated returns.  Sales are recognized 
when the related products are shipped.  The Company warrants products against 
defects and has a policy concerning the return of products.

CASH AND CASH EQUIVALENTS

The Companies consider all highly liquid investments with original maturities 
of three months or less to be classified as cash equivalents. Cash 
equivalents are carried at cost, which approximates market.

INVENTORY

Inventory is stated at the lower of cost or market, with cost being 
determined on a weighted average cost basis.  Costs include direct materials, 
direct labor and certain indirect manufacturing overhead expenses.
                                       70

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost.  Depreciation and amortization of 
property and equipment has been computed by the straight-line method 
beginning January 1, 1995.  Depreciation and amortization of property and 
equipment in prior years was computed by the double declining balance-method. 
 The straight-line method of depreciation was adopted in order to provide for 
depreciation and amortization expense on a basis more consistent with the 
property and equipment's actual utilization and has been applied to 
acquisitions of prior years.  The effect of the change in 1995 was to 
increase income from operations by approximately $95,000.  The pro forma 
amounts shown on the statement of income have been adjusted for the effect of 
retroactive application of depreciation and amortization on the straight-line 
basis.

Additionally, the Companies changed the estimated useful lives for its 
property and equipment beginning in 1995. The effect of this change did not 
have a material impact on income from operations for 1995. Depreciation and 
amortization expense are provided over the following estimated useful lives:

    Machinery and equipment                 3 - 7 years
    Office computer equipment and software  3 - 5 years
    Furniture and fixtures                  5 - 7 years
    Leasehold improvements                  Shorter of useful life or remaining
                                             term of the lease

BANK OVERDRAFTS

Bank overdrafts represent outstanding checks in excess of funds on deposit 
where legal right to offset does not exist.

INCOME TAXES

In 1993, 1st Tech elected and was treated for federal and certain state 
income tax purposes as a C-Corporation.  In 1994, 1st Tech changed its 
federal tax status from a C-Corporation to an S-Corporation.

In 1993, DarkHorse elected and was treated for federal and certain state 
income tax purposes as a C-Corporation. DarkHorse changed its federal tax 
status from a C-Corporation to an S-Corporation in 1995.

In 1995, the Companies have elected and have been treated for federal and 
certain state income tax purposes as an S-Corporation under Subchapter S of 
the Internal Revenue Code of 1986, as amended.  As a result, the income of 
the Companies for federal and certain state income tax purposes is included 
in the income tax return of the individual shareholders.  The accompanying 
combined financial statements include recognition of those federal and state 
income taxes which are levied on the Companies.  (See Note 3 for pro forma 
income tax information.)

NEW ACCOUNTING PRONOUNCEMENTS

In March 1995, Statement of Financial Accounting Standards No. 121, 
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets 
to be Disposed Of" (FAS 121), was issued.  Under FAS 121, an impairment loss 
must be recognized, for long-lived assets and certain identifiable 
intangibles to be held and used by an entity, whenever events or changes in 
circumstances indicate that the carrying amount of an asset may not be 
recoverable. FAS 121 is effective for financial statements issued for fiscal 
years beginning after December 15, 1995, and must be adopted on a prospective 
basis.  Restatement of previously issued financial statements is not 
permitted.  The Companies adopted FAS 121 effective January 1, 1996.  Such 
adoption did not have a material effect on the financial condition or results 
of operations of the Companies.

                                       71

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the financial statements and 
the reported amount of revenues and expenses during the reporting period.  
Actual results could differ from those estimates.

3.  PRO FORMA INFORMATION (UNAUDITED):

Pro forma net income has been determined assuming that the Companies had been 
taxed as C-Corporations for federal and certain state income tax purposes 
since January 1, 1993.  The pro forma adjustments to reflect federal and 
state income tax assume a blended tax rate of 37 percent.  Additionally, the 
pro forma amounts shown on the statements of income have been adjusted for 
the cumulative effect of change in accounting principle.  (See Note 2.)

4.  INVENTORIES:

Inventories consist of the following:

The Companies have $440,704 and $195,506 of property and equipment acquired 
under capital leases as of December 31, 1995 and 1994, respectively.  The 
accumulated depreciation related to these assets totaled $81,312 and $30,257 
as of December 31, 1995 and 1994, respectively.  The related depreciation 
expense was $51,055, $27,929 and $2,328 for the years ended 1995, 1994 and 
1993, respectively.

6.  REVOLVING CREDIT NOTE:

Effective October 1994, 1st Tech obtained a revolving credit note with a 
financial institution which provided for maximum borrowings of $5,000,000.  
In July 1995, 1st Tech restructured the revolving credit note with the same 
financial institution increasing maximum borrowings to $12,000,000.  Advances 
bear interest at the financial institution's prime rate plus 2 percent (10.50 
percent as of December 31, 1995).  The borrowings are secured by assets. As a 
condition precedent to the restructured note, a $35,000 commitment fee was 
paid upon closing.  In addition, the revolving credit note contains certain 
restrictive covenants.  Specifically, 1st Tech must maintain a minimum 
tangible net worth as determined by the financial institution, profitability 
by quarter as well as compliance with certain financial ratios specified by 
the financial institution.  1st Tech is required to report its borrowing 
base, determined by eligible accounts receivable, to the financial 
institution each week and cannot enter into any additional debt agreements 
without prior approval from the financial institution.  Indebtedness under 
the note was guaranteed by 1st Tech's sole shareholder.  As of December 31, 
1995 and 1994, advances outstanding under the revolving credit note amounted 
to $6,915,000 and $3,313,000, respectively.  As of December 31, 1995, 
$5,085,000 was available for future borrowings.  The revolving credit note is 
discretionary and may be modified, suspended or terminated at the election of 
the lender at any time.

The carrying amount of the revolving credit note approximates fair value.

As of December 31, 1995, 1st Tech was in violation of certain covenants of 
the revolving credit note.  1st Tech obtained a one-time waiver from the 
financial institution with respect to these covenant violations.  In 
addition, as of our report date, the company was not in compliance with 
certain debt covenants.  A debt waiver has been obtained by the company for 
all of the periods.

7.  LEASE COMMITMENTS:

The Companies lease certain equipment and office space under noncancelable 
leases with expiration dates ranging from 1996 through 2000.

Future minimum principal lease payments under all leases are as follows:

$115,000 and $66,000 for 1995, 1994 and 1993, respectively.

8.  INCOME TAXES:

Effective January 1, 1994, 1st Tech converted from a C-Corporation to an 
S-Corporation.

Effective January 1, 1995, DarkHorse converted from a C-Corporation to an 
S-Corporation.  Upon conversion, DarkHorse computed its built-in gain, 
principally relating to inventory, for federal income tax purposes as 
approximately $33,000.

The provision for income taxes for the years ended December 31, 1995, 1994 
and 1993, consists of the following:

                                 1995      1994       1993

9.  RELATED-PARTY TRANSACTIONS:

1st Tech's sole shareholder has a one-third interest in DarkHorse.  During 
1995, 1994 and 1993, the Companies had certain intercompany transactions 
which are eliminated in the combined financial statements.

In November 1995, 1st Tech entered into an operating lease for certain 
manufacturing equipment with its sole shareholder.  The lease extends for a 
period of 36 months with monthly payments totaling $6,200.  The future 
minimum lease payments associated with this lease are included in the amounts 
disclosed in Note 7.  In conjunction with the acquisition of the Companies, 
as described in Note 14, the leased equipment was purchased from the 
shareholder in May 1996 for $200,000 and the lease was canceled.

1st Tech made a loan to its sole shareholder during 1994 of approximately 
$195,300.  Interest on the loan accrues on a monthly basis at 1st Tech's 
incremental borrowing rate of prime plus 2 percent (10.50 percent as of 
December 31, 1995).  Amounts due from the sole shareholder relating to this 
loan and other cash advances totaled $199,000 and $148,000 as of December 31, 
1995 and 1994, respectively.  In conjunction with the acquisition of the 
Companies, as described in Note 14, the then outstanding balance of $204,772 
was charged to equity as a deemed shareholder distribution.

During 1993, 1st Tech's sole shareholder loaned $443,000 to 1st Tech.  The 
loan is subordinated to 1st Tech's existing notes payable to bank, and no 
principal amounts can be repaid to the sole shareholder as long as amounts 
remain outstanding under the bank line of credit.  The loan bears interest at 
prime plus 2-1/2 percent (11 percent as of December 31, 1995).  Interest 
payments on the loan are due quarterly and the principal was due December 31, 
1995, with a contingency option to extend the due date up to an additional 
three years.  In conjunction with the acquisition of the Companies, as 
described in Note 14, the loan was credited to equity as a deemed shareholder 
contribution.

Additionally, as of December 31, 1993, 1st Tech had approximately $331,000 
payable to Stratum Technologies, Inc., a separate corporation wholly owned by 
the sole shareholder of 1st Tech Corporation.  The balance was subsequently 
paid during 1994.

                                       74

<PAGE>

In 1994, 1st Tech loaned approximately $40,000 to Granite 
Software, Inc., a company 20 percent owned by 1st Tech's sole shareholder.  
During 1995, this amount was written off as uncollectible.

During 1994, DarkHorse repurchased certain ownership interests from two 
shareholders for amounts totaling approximately $74,000 in exchange for notes 
payable bearing interest at 9 percent per annum.  Principal payments totaling 
approximately $69,000, representing the remaining outstanding balances, were 
made during 1995 on these notes payable.

Additionally, as of December 31, 1994, approximately $232,400 of salaries and 
bonuses were outstanding to 1st Tech's shareholders.  During 1995, $152,400 
was converted to notes payable bearing interest at 9 percent per annum; while 
the remaining $80,000 was paid in cash.  Principal payments totaling 
approximately $92,000 were made on these notes payable during 1995.  The 
remaining amounts outstanding on the notes, including accrued interest, were 
paid in full in April 1996.

10.  SIGNIFICANT CUSTOMERS:

The Companies sell their products to a variety of domestic-based memory 
aftermarkets and original equipment manufacturers in the electronics 
industry.  The Companies perform ongoing credit evaluations of their 
customers' financial condition and, generally, require no collateral from 
customers.  If the financial condition and operations of these customers 
deteriorate, the Companies' operating results could be adversely affected.

For the year ended December 31, 1994, the Companies had one customer that

taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present

                                   ARTICLE III

                                    DIRECTORS

3.01      The number of directors which shall constitute the whole board shall
not be less than three nor more than fifteen.  The first board shall consist of
three directors.  Thereafter, within the limits above specified, the number of
directors shall be determined by resolution of the board of directors or by the
stockholders at the annual meeting.  The directors shall be classified with
respect to the time for which they shall severally hold office by dividing them
into three classes, each consisting of 33-1/3% of the whole number of the board
of directors, as nearly equal in number as possible, one class to hold office
initially for a term expiring at the annual meeting of stockholders to be held
in 1997, another to hold office initially for a term expiring at the annual
meeting of stockholders to be held in 1998 and another to hold office initially
for a time expiring at the annual meeting of stockholders to be held in 1999,
with members of each new class to hold office until their successors have been
duly elected and have qualified.  At each annual meeting of the stockholders of
the corporation, the successors to the class of directors whose term expires at
the meeting shall be elected to hold office for a term expiring at the annual
meeting held in the third year following the term of their election.  Directors
need not be stockholders.

3.02      When the number of directors is changed, any newly created
directorships or any increase in directorships shall be so apportioned among the
classes as to make all classes as nearly equal in number as possible.  When the
number of directors is increased by the board of directors and any newly created
directorships are filled by the board of directors, there shall be no
classification of the additional directors until the next annual meeting of
stockholders.  Vacancies in newly created directorships resulting from any
increase in the authorized number of directors may be filled by a majority of
the directors then in office, though less than a quorum, or by a sole remaining
director, and the directors so chosen shall hold office until the next annual
election and until their successors are duly elected and shall qualify, unless
sooner displaced.  If there are no directors in office, then an election of
directors may be held in the manner provided by the Wyoming Business Corporation
Act.

3.03      The business of the corporation shall be managed by or under the
direction of its board of directors which may exercise all such powers of the
corporation and do all such lawful 


                                        3

<PAGE>

acts and things as are not by statute or these by-laws directed or required to
be exercised or done by the stockholders.

MEETINGS OF THE BOARD OF DIRECTORS

3.04      The board of directors of the corporation may hold meetings, both
regular and special, either within or without the State of Wyoming.

3.05      The first meeting of each newly elected board of directors shall be
held at such time and place as shall be fixed by the vote of the stockholders at
the annual meeting, and no notice of such meeting shall be necessary to the
newly elected directors in order legally to constitute the meeting, provided a
quorum shall be present.  In the event of the failure of the stockholders to fix
the time or place of such first meeting of the newly elected board of directors,
or in the event such meeting is not held at the time and place so fixed by the
stockholders, the meeting may be held at such time and place as shall be
specified in a notice given as hereinafter provided for special meetings of the
board of directors, or as shall be specified in a written waiver signed by all
of the directors.

3.06      Regular meetings of the board of directors may be held without notice
at such time and at such place as shall from time to time be determined by the
board.

3.07      Special meetings of the board may be called by the president on two
days' notice to each director, either personally or by mail or by telegram.
Special meetings shall be called by the president or secretary in like manner
and on like notice on the written request of two directors, unless the board
consists of only one director, in which case special meetings shall be called by
the president or secretary in like manner and on like notice on the written
request of the sole director.

3.08      At all meetings of the board, a majority of directors shall constitute
a quorum for the transaction of business and the act of a majority of the
directors present at any meeting at which there is a quorum shall be the act of
the board of directors, except as may be otherwise specifically provided by
statute or by the certificate of incorporation.  If a quorum shall not be
present at any meeting of the board of directors, the directors present thereat
may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present.

3.09      Unless otherwise restricted by the certificate of incorporation or
these by-laws, any action required or permitted to be taken at any meeting of
the board of directors or of any committee thereof may be taken without a
meeting, if all members of the board or committee, as the case may be, consent
thereto in writing, and the writing or writings are filed with the minutes of
proceedings of the board or committee.

3.10      Unless otherwise restricted by the certificate of incorporation or
these by-laws, members of the board of directors or any committee designated by
the board of directors may participate in a meeting of the board of directors,
or any committee designated by the board of 


                                        4

<PAGE>

directors, means of conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other, and
such participation in a meeting shall constitute presence in person at the
meeting.

COMMITTEES OF DIRECTORS

3.11      The board of directors may, by resolution passed by a majority of the
whole board of directors, designate one or more committees, each committee to
consist of one or more of the directors of the corporation.  The board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee.

          Any such committee, to the extent provided in the resolution of the
board of directors, shall have and may exercise all the powers and authority of
the board of directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the certificate of incorporation, adopting an
agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the corporation's property and
assets, recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the by-laws of the corporation; and
unless the resolution or the certificate of incorporation expressly so provides,
no such committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock or to adopt a certificate of ownership and
merger.  Such committee or committees shall have such name or names as may be
determined from time to time by resolution adopted by the board of directors.

3.12      Each committee shall keep regular minutes of its meetings and report
the same to the board of directors when required.

COMPENSATION OF DIRECTORS

3.13      Unless otherwise represented by the certificate of incorporation or
these by-laws, the board of directors shall have the authority to fix the
compensation of directors.  The directors may be paid their expenses, if any, of
attendance at each meeting of the board of directors and may be paid a fixed sum
for attendance at each meeting of the board of directors or a stated 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

3.14      Unless otherwise restricted by the certificate of incorporation or
these by-laws, any director or the entire board of directors may be removed,
with or without cause, by the holders of a majority of shares entitled to vote
at an election of directors.

4.01      Whenever, under the provisions of the statutes or of the certificate
of incorporation or of these by-laws, notice is required to be given to any
director or stockholder, it shall not be construed to mean personal notice, but
such notice may be given in writing, by mail, addressed to such director or
stockholder, at his address as it appears on the records of the corporation,
with postage thereon prepaid, and such notice shall be deemed to be given at the
time when the same shall be deposited in the United States mail.  Notice to

4.02      Whenever any notice is required to be given under the provisions of
the statutes or of the certificate of incorporation or of these by-laws, a

equivalent thereto.

          (a)  PURCHASE FOR INVESTMENT; TRANSFERABILITY.  You represent and
     warrant to the Company that the Warrants and the shares of Underlying
     Securities are being acquired for investment and not with a view to the
     distribution or resale thereof.  You agree that the Warrants and the
     Underlying Securities may not be transferred, sold, assigned or
     hypothecated, except pursuant to a registration statement that has become
     effective under the Act, setting forth the terms of such offering, the
     underwriting discount and commissions and any other pertinent data with
     respect thereto, unless you have provided the Company with an opinion of
     counsel reasonably acceptable to the Company that such registration is not
     required.  You acknowledge that holders of the Company's Common Stock
     currently are not afforded the use of Rule 144 promulgated under the Act
     and that the Company is under no obligation to take the actions necessary
     to make such Rule available to you.

          (b)  LEGEND.  Each certificate representing Underlying Securities
     shall be imprinted with a legend in substantially the following form:

          The securities represented by this certificate were issued
          upon exercise of a stock purchase warrant granted effective
          May 17, 1995, have not been registered or qualified under
          the Securities Act of 1933 or any applicable state
          securities laws, and may not be sold or transferred in the
          absence of effective registration or qualified under such
          laws or an exemption from registration or qualification
          thereunder.  The transfer of such security also is subject
          to the conditions specified in the Warrant Agreement, dated
          as of May 17, 1995, between the Corporation and certain
          subscribers, and the Corporation reserves the right to
          refuse the transfer of such security until such conditions
          have been fulfilled with respect to such transfer.  Upon
          written request, a copy of such agreement will be furnished
          by the Corporation to the holder hereof without charge.  Any
          transferee of the security represented by this certificate
          also agrees to be bound by the terms and conditions of such
          Warrant Agreement.

          THE WARRANTS REPRESENTED BY THIS WARRANT CERTIFICATE AND ANY
          SHARES ACQUIRED UPON THE EXERCISE THEREOF ARE SUBJECT TO A
          HOLD PERIOD AND MAY NOT BE TRADED IN BRITISH COLUMBIA UNTIL
          THE EXPIRY OF THE HOLD PERIOD EXCEPT AS PERMITTED BY THE
          SECURITIES ACT (BRITISH COLUMBIA) AND REGULATIONS MADE UNDER
          THE ACT.  FOR CANADIAN RESIDENTS, THE HOLD PERIOD EXPIRES ON
          MAY 17, 1996; HOWEVER, PURSUANT TO THE POLICIES OF THE
          VANCOUVER STOCK EXCHANGE, THE WARRANTS, IF EXERCISABLE FOR A
          PERIOD OF MORE THAN ONE YEAR, REMAIN NON-TRANSFERABLE FOR
          THE BALANCE OF THE EXERCISE PERIOD.

          (c)  Unless the content otherwise requires, references in this
     Section 3 to "you" or "your" shall mean and include a Warrantholder
     or a holder of Underlying Securities, as the case may be.

4.   EXERCISE OF WARRANTS.

     Warrants may only be exercised in full by the Warrantholder by surrender 
of the Warrant, with the form of subscription at the end thereof duly 
executed by such Warrantholder, to the Company at its principal executive 
offices, accompanied by certified or bank cashier's check payable to the 
order of the Company in the full amount obtained by multiplying the number of 
Units represented by the respective Warrant or Warrants by the Purchase Price 
per Unit.

5.   DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE.

     Any exercise of the Warrants pursuant to Section 4 hereof shall be deemed
to have been effective immediately prior to the close of business on the date on
which the Warrants with the subscription form and the check for the aggregate
Purchase Price shall have been received by the Company; except that the Company
shall not be required to open its stock transfer books in order to effect an
exercise, and the effective time in such event shall be the date the stock
transfer books are reopened.  At such time, the person or persons in whose name
or names any certificate or certificates for shares of Underlying Securities
shall be issuable upon such exercise shall be deemed to have become the holder
or holders of record of the shares of Underlying Securities so purchased.  As
soon as practicable after the exercise of any Warrant, the Company, at its
expense (including the payment by it of any applicable issue taxes), will cause
to be issued in the name of, and delivered to, the purchasing Warrantholder, a
certificate or certificates for the number of fully paid and nonassessable
shares of the Underlying Securities to which such Warrantholder shall be
entitled upon such exercise, plus in lieu of any fractional share to which such
Warrantholder would otherwise be entitled, cash in an amount determined pursuant
to Subsection 7(h) hereof.  Such certificate shall contain the legend required
by Subsection 3(b) hereof.

6.   ANTI-DILUTION PROVISIONS.

     The Warrants are subject to the following terms and conditions during the 
term thereof:

          (a)  STOCK DISTRIBUTIONS, SPLITS AND COMBINATIONS; ADJUSTMENTS.  In
     case of (i) the outstanding shares of Common Stock (or Other Securities)
     shall be subdivided into a greater number of shares, (ii) a non-cash
     dividend in Common Stock (or Other Securities) shall be paid in respect of
     Common Stock (or Other Securities), or (iii) the outstanding shares of
     Common Stock (or Other Securities) shall be combined in to a smaller number
     of shares thereof, the number of shares of Underlying Securities per Unit
     subsequent to such subdivision or combination or at the record date of such
     dividend or distribution shall simultaneously with the effectiveness of
     such subdivision or combination or immediately after the record date of
     such dividend or distribution be equal to the number of shares of Common
     Stock and Other Securities a holder would have owned and had a right to
     receive as a result of such subdivision, combination, dividend or
     distribution if such holder had actually held of record immediately prior
     to the effectiveness of such subdivision or combination or immediately
     prior to the record date of such dividend or distribution the number of
     shares of Underlying Securities purchasable per Unit immediately prior to
     the effectiveness of such subdivision or combination or the record date of
     such dividend or distribution.

          (b)  REORGANIZATIONS AND RECAPITALIZATIONS.  In case the Company shall
     be reorganized or recapitalized by reclassifying its outstanding Common
     Stock (or Other Securities) without par value to stock with par value,
     then, as a condition of such reorganization or recapitalization, as the
     case may be, immediately after the effective time of such reorganization or
     recapitalization, each Warrantholder shall thereafter have the right to
     purchase, upon the terms and conditions specified herein, the number of
     shares of Underlying Securities per Unit that a holder would have owned and
     had the right to receive as a result of such reorganization or
     recapitalization if such holder had held of record the number of shares of
     Underlying Securities per Unit immediately prior to such reorganization or
     recapitalization.  If any consolidation or merger of the Company with
     another corporation, or the sale of all or substantially all of its assets
     to another corporation, shall be effected in such a way that holders of
     Common Stock and Other Securities shall be entitled to receive stock,
     securities or assets with respect to or in exchange for Common Stock and
     Other Securities, then, as a condition of such consolidation, merger or
     sale, immediately after the effective time of such consolidation, merger or
     sale, the Warrantholders shall thereafter, subject to the last sentence of
     this Subsection, have the right to purchase and receive upon the basis and
     upon the terms and conditions specified in this Warrant Agreement, the
     number of shares of Underlying Securities per Unit that a holder would have
     owned and had a right to receive as a result of such consolidation, merger
     or sale if such holder had actually held of record immediately prior to
     such consolidation, merger or sale the number of shares of Underlying
     Securities purchasable per Unit immediately prior to such consolidation,
     merger or sale.  If the Company is merged into or consolidated with another
     corporation under circumstances where the Company is not the surviving
     corporation or where the




                                        5


<PAGE>




     Company will be a wholly owned subsidiary of another corporation
     (except where such merger or consolidation is effected merely in order to
     recapitalize or reincorporate the Company), or if the Company sells or
     otherwise disposes of all or substantially all of its property or assets
     to another corporation, all outstanding Warrants may be canceled by the
     Board of Directors of the Company as of the effective date of any such
     merger, consolidation or sale, provided that (i) written notice of such
     cancellation is given to each holder of a Warrant not later than 30 days
     prior to such effective date and (ii) each holder of a Warrant shall
     have the right to exercise such Warrant in full during the said 30-day
     period preceding the effective date of such merger, consolidation or sale.

          (c)  EFFECT OF DISSOLUTION OR LIQUIDATION.  In case the Company shall
     dissolve or liquidate all or substantially all of its assets, all rights
     under this Warrant Agreement and the Warrants shall terminate as of the
     date upon which a certificate of dissolution or liquidation shall be filed
     with the Secretary of State of Wyoming (or, if the Company theretofore
     shall have been merged or consolidated with a corporation incorporated
     under the laws of another state, the state of incorporation on the date
     upon which action of equivalent effect shall have been taken); provided,
     however, that (i) no dissolution or liquidation shall affect the rights
     under Subsection (b) hereof of any Warrantholder and (ii) if the Company's
     Board of Directors shall propose to dissolve or liquidate the Company, each
     Warrantholder shall be given written notice of such proposal at the earlier
     of (i) the time when the Company's shareholders are first given notice of
     the proposal or (ii) the time when notice to the Company's shareholders is
     first required.

          (d)  NOTICE OF CHANGE OF UNDERLYING SECURITIES.  Whenever the number
     of shares of Underlying Securities per Unit or the kind or amount of
     securities or assets purchasable pursuant to the Warrants shall be adjusted
     pursuant to any of the provisions of this Warrant Agreement, or the number
     of shares of Underlying Securities or the kind or amount of securities or
     assets receivable upon conversion of Underlying Securities shall be
     adjusted pursuant to the terms thereof, the Company shall forthwith
     thereafter cause to be sent to each Warrantholder a notice setting forth
     such adjustment and also setting forth in detail the facts requiring such
     adjustments.
     
7.   FURTHER COVENANTS OF THE COMPANY.

          (a)  DILUTION OR IMPAIRMENTS.  The Company will not, by amendment of
     its certificate of incorporation or through any reorganization, transfer of
     assets, consolidation, merger, dissolution, issue or sale of securities, or
     any other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms of the Warrant or of this Warrant
     Agreement, but will at all times in good faith assist in the carrying out
     of all such terms and in the taking of all such action as may be necessary
     or appropriate in order to protect the rights of the Warrantholders against
     dilution or other impairment.  Without limiting the generality of the
     foregoing, the Company:





                                        6

<PAGE>




               (i)  shall at all times reserve and keep available, solely for
          issuance and delivery upon the exercise of the Warrants, all shares of
          the Underlying Securities from time to time issuable upon the exercise
          of the Warrants and shall use its best efforts to ensure that the par
          value per share, if any, of the Underlying Securities is at all times
          equal to or less than the then effective Purchase Price per share of
          Underlying Securities; and
          
               (ii)  will take all such action as may be necessary or
          appropriate in order that the Company may validly and legally issue
          fully paid and nonassessable shares of Common Stock and Other
          Securities upon the exercise of the Warrants from time to time
          outstanding.
          
          (b)  TITLE TO STOCK.  All shares of the Underlying Securities
     delivered upon the exercise of the Warrants shall be validly issued, fully
     paid and nonassessable; each holder of a Warrant shall receive good and
     marketable title to the Underlying Securities, free and clear of all voting
     and other trust arrangements, liens, encumbrances, equities and claims
     whatsoever; and the Company shall have paid all taxes, if any, in respect
     of the issuance thereof.
     
          (c)  LISTING ON SECURITIES EXCHANGES; REGISTRATION.  If the Company at
     any time shall list any Common Stock on any national securities exchange,
     the Company will, at its expense, simultaneously list on such exchange,
     upon official notice of issuance upon the exercise of the Warrants, and
     maintain such listing of, all shares of Common Stock included in the
     Underlying Securities from time to time issuable upon the exercise of the
     Warrants or upon conversion of Underlying Securities, and the Company will
     so list on any national securities exchange, will so register, and will
     maintain such listing of, any Other Securities if and at the time that any
     securities of such class shall be listed on such national securities
     exchange by the Company.  You shall have no right to require the Company to
     register the Warrants.  The Company will use its best efforts to register
     the shares of Common Stock underlying the Warrants and to keep such
     registration statement effective for a period of no less than two years.
     
          (d)  REMEDIES.  The Company stipulates that the remedies at law of the
     Warrantholder or any holder of Underlying Securities in the event of any
     default or threatened default by the Company in the performance of or
     compliance with any of the terms of this Warrant Agreement or the Warrants
     are not and will not be adequate and that such terms may be specifically
     enforced by a decree of the specific performance of any agreement contained
     herein or in the Warrants or by an injunction against a violation of any of
     the terms hereof or thereof or otherwise.
     
          (e)  EXCHANGE OF WARRANTS.  Subject to Subsection 3(a) hereof, upon
     surrender or exchange of any Warrant to the Company, the Company at its
     expense will promptly issue and deliver to or upon the order of the holder
     thereof a new Warrant of like tenor, in the name of such holder or as such
     holder (upon payment by such Warrantholder of any applicable transfer
     taxes) may direct, calling in the aggregate for the purchase of the




                                        7



<PAGE>



     number of shares of the Underlying Securities called for on the face or
     faces of the Warrant or Warrants so surrendered.  The Warrants and all
     rights thereunder are transferable in whole or in part upon the books of
     the Company by the registered holder thereof subject to the provisions of
     Subsection 3(a) hereof, in person or by duly authorized attorney, upon
     surrender of the Warrant, duly endorsed, at the principal office of the
     Company.
     
          (f)  REPLACEMENT OF WARRANTS.  Upon receipt of evidence reasonably
     satisfactory to the Company of the loss, theft, destruction or mutilation
     of any Warrant, and in the case of any such loss, theft or destruction,
     upon delivery of an indemnity agreement reasonably satisfactory in form and
     amount to the Company, or in the case of such mutilation, upon surrender
     and cancellation of such Warrant, the Company, at the expense of the
     Warrantholder, will execute and deliver, in lieu thereof, a new Warrant of
     like tenor.
     
          (g)  REPORTING BY THE COMPANY.  The Company agrees that during the
     term of the Warrants and as long as you hold Underlying Securities, it will
     use its best efforts to keep current in the filing of all forms and other
     materials, if any, which it may be required to file with the appropriate
     regulatory authority pursuant to the Exchange Act and all other forms and
     reports required to be filed with any regulatory authority having
     jurisdiction over the Company.
     
          (h)  FRACTIONAL SHARES.  No fractional shares of Underlying Securities
     are to be issued upon the exercise of any Warrant, but the Company shall
     pay a cash adjustment in respect of any fraction of a share that would
     otherwise be issuable in an amount equal to such fraction multiplied by the
     closing market price per share of Underlying Securities on the day of
     exercise, as determined by the closing bid and asked price regular way on
     the principal national securities exchange on which the Underlying
     Securities is listed or admitted to trading, or if not listed or admitted
     to trading on any national securities exchange, the average of the highest
     reported bid and lowest reported asked price over the preceding 30-day
     period as furnished by the National Quotation Bureau Incorporated;
     provided, however, that if the Underlying Securities are not traded in such
     manner that the quotations referred to herein are available, the market
     price shall be deemed to be the fair market value of such Underlying
     Securities as reasonably determined by the Board of Directors.
     
8.   OTHER WARRANTHOLDERS.

     The Warrants are issued upon the following terms, to all of which each
holder or owner thereof by the taking thereof consents and agrees: (a) any
person who shall become a transferee, within the limitations on transfer imposed
by Subsection 3(a) hereof, shall take such Warrant subject to the provisions of
Subsection 3(a) hereof and the other provisions hereof and thereupon shall be
authorized to represent himself as absolute owner thereof and, subject to the
restrictions contained in this Warrant Agreement, shall be empowered to transfer
absolute title by endorsement and delivery thereof to a permitted bonafide
purchaser for value; (b) each prior



                                        8


<PAGE>




taker or owner waives and renounces all of his equities or rights in such
Warrant in favor of each such permitted bonafide purchaser, and each such
permitted bonafide purchaser shall acquire absolute title thereto and to all
rights presented thereby; (c) until such time as the respective Warrant is
transferred on the books of the Company, the Company may treat the registered
holder thereof as the absolute owner thereof for all purposes, notwithstanding
any notice to the contrary; and (d) all references to the words "you" and "your"
in this Warrant Agreement shall be deemed to apply with equal effect to any
person to whom a Warrant has been transferred in accordance with the terms
hereof, and where appropriate, to any person holding shares of the Underlying
Securities.

9.   MISCELLANEOUS.

     All notices, certificates, and other communications from or at the request
of the Company to any Warrantholder shall be mailed by first class, registered,

Warrantholder, or, if no notice of transfer has been received by the Company, to

<PAGE>

The exercise price and the number of shares which can be purchased by the 
Warrant Holder upon the exercise of this warrant certificate shall be subject 
to adjustment in the events and in the manner following:

      (1)  If and whenever the shares at any time outstanding shall be
           subdivided into a greater or consolidated into a lesser number of
           shares, the exercise price shall be decreased or increased
           proportionately as the case may be; upon any such subdivision or
           consolidation, the number of shares which can be purchased upon the
           exercise of this warrant certificate shall be increased or decreased
           proportionately as the case may be. 

      (2)  In case of any capital reorganization or of any reclassification of
           the capital of the Company or in case of the consolidation, merger 
           or amalgamation of the Company with or into any other company, this
           warrant certificate shall after such capital reorganization,
           reclassification of capital, consolidation, merger or amalgamation
           confer the right to purchase the number of shares or other 
           securities of the Company or of the Company resulting from such
           capital reorganization, reclassification, consolidation, merger
           or amalgamation, as the case may be, to which the Warrant Holder 
           of the shares deliverable at the time of such capital 
           reorganization, reclassification of capital, consolidation, merger
           or amalgamation, upon the exercise of this warrant certificate would 
           have been entitled.  On such capital reorganization, 
           reclassification, consolidation, merger or amalgamation appropriate 
           adjustments shal be made in the application of the provisions set 
           forth herein with respect to the rights and interest thereafter of 
           the Warrant Holder of this warrant certificate so that the provisions
           set forth herein shall thereafter be applicable as nearly as may 
           reasonably be in relation to any shares or other securities 
           thereafter deliverable on the exercise of this warrant certificate. 

      (3)  The rights of the Warrant Holder evidenced hereby are to purchase
           shares prior to or on the date set out on the face of this warrant
           certificate.  If there shall, prior to the exercise of any of the
           rights evidenced hereby, be any reorganization of the authorized
           capital of the Company by way of consolidation, merger, subdivision,
           amalgamation or otherwise, or the payment of any stock dividends,
           then there shall automatically be an adjustment in either or both of
           the number of shares which may be purchased pursuant hereto or the
           price at which such shares may be purchased so that the rights
           evidenced hereby shall thereafter as reasonably as possible be
           equivalent to those originally granted hereby.  The Company shall
           have the sole and exclusive power to make 

      (4)  The adjustments provided for herein in the subscription rights
           represented by this warrant certificate are cumulative. 

If at any time while this warrant certificate is outstanding the Company 
shall pay any stock dividend upon the common shares of the Company in respect 
of which the right to purchase is herein given, the Company shall thereafter 

<PAGE>

deliver at the time of purchase of shares hereunder, in addition to the 
number of shares in respect of which the right to purchase is then being 
exercised, the additional number of shares of the appropriate class as would 
have been outstanding on the record date for the payment of the stock 
dividend.
 The holding of this warrant certificate or the warrants represented hereby 
shall not constitute the Warrant Holder a member of the Company.

Time shall be of the essence hereof.

This warrant certificate shall not be valid for any purchase whatever until 
it has been countersigned by or on behalf of the Company's Registrar and 
Transfer Agent.

IN WITNESS WHEREOF THE COMPANY has caused this warrant certificate to be 
issued by its duly authorized signatory.

          (b)  LEGEND.  Each certificate representing Underlying Securities
     shall be imprinted with a legend in substantially the following form:

          The securities represented by this certificate were issued
          upon exercise of a stock purchase warrant granted effective
          December 20, 1995, have not been registered or qualified
          under the Securities Act of 1933 or any applicable state
          securities laws, and may not be sold or transferred in the
          absence of effective registration or qualified under such
          laws or an exemption from registration or qualification
          thereunder.  The transfer of such security also is subject
          to the conditions specified in the Warrant Agreement, dated
          as of January 16, 1996, with an effective date of
          December 20, 1995, between the Corporation and certain
          subscribers, and the Corporation reserves the right to
          refuse the transfer of such security until such conditions
          have been fulfilled with respect to such transfer.  Upon
          written request, a copy of such agreement will be furnished
          by the Corporation to the holder hereof without charge.  Any
          transferee of the security represented by this certificate
          also agrees to be bound by the terms and conditions of such
          Warrant Agreement.

          THE WARRANTS REPRESENTED BY THIS WARRANT CERTIFICATE AND ANY
          SHARES ACQUIRED UPON THE EXERCISE THEREOF ARE SUBJECT TO A
          HOLD PERIOD AND MAY NOT BE TRADED IN BRITISH COLUMBIA UNTIL
          THE EXPIRY OF THE HOLD PERIOD EXCEPT AS PERMITTED BY THE
          SECURITIES ACT (BRITISH COLUMBIA) AND REGULATIONS MADE UNDER
          THE ACT.  FOR CANADIAN RESIDENTS, THE HOLD PERIOD EXPIRES ON
          JANUARY 16, 1997; HOWEVER, PURSUANT TO THE POLICIES OF THE
          VANCOUVER STOCK EXCHANGE, THE WARRANTS, IF EXERCISABLE FOR A
          PERIOD OF MORE THAN ONE YEAR, REMAIN NON-TRANSFERABLE FOR
          THE BALANCE OF THE EXERCISE PERIOD.

          (c)  Unless the content otherwise requires, references in this
     Section 3 to "you" or "your" shall mean and include a Warrantholder or a
     holder of Underlying Securities, as the case may be.

4.   EXERCISE OF WARRANTS.

     Warrants may only be exercised in full by the Warrantholder by surrender of
the Warrant, with the form of subscription at the end thereof duly executed by
such Warrantholder, to the Company at its principal executive offices,
accompanied by certified or bank cashier's check payable to the order of the
Company in the full amount obtained by multiplying the number of Units
represented by the respective Warrant or Warrants by the Purchase Price per
Unit.

5.   DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE.
     Any exercise of the Warrants pursuant to Section 4 hereof shall be deemed
to have been effective immediately prior to the close of business on the date on
which the Warrants with the subscription form and the check for the aggregate
Purchase Price shall have been received by the Company; except that the Company
shall not be required to open its stock transfer books in order to effect an
exercise, and the effective time in such event shall be the date the stock
transfer books are reopened.  At such time, the person or persons in whose name
or names any certificate or certificates for shares of Underlying Securities
shall be issuable upon such exercise shall be deemed to have become the holder
or holders of record of the shares of Underlying Securities so purchased.  As
soon as practicable after the exercise of any Warrant, the Company, at its
expense (including the payment by it of any applicable issue taxes), will cause
to be issued in the name of, and delivered to, the purchasing Warrantholder, a
certificate or certificates for the number of fully paid and nonassessable
shares of the Underlying Securities to which such Warrantholder shall be
entitled upon such exercise, plus in lieu of any fractional share to which such
Warrantholder would otherwise be entitled, cash in an amount determined pursuant
to Subsection 7(h) hereof.  Such certificate shall contain the legend required
by Subsection 3(b) hereof.

6.   ANTI-DILUTION PROVISIONS.

     The Warrants are subject to the following terms and conditions during the
term thereof:

          (a)  STOCK DISTRIBUTIONS, SPLITS AND COMBINATIONS; ADJUSTMENTS.  In
     case of (i) the outstanding shares of Common Stock (or Other Securities)
     shall be subdivided into a greater number of shares, (ii) a non-cash
     dividend in Common Stock (or Other Securities) shall be paid in respect of
     Common Stock (or Other Securities), or (iii) the outstanding shares of
     Common Stock (or Other Securities) shall be combined in to a smaller number
     of shares thereof, the number of shares of Underlying Securities per Unit
     subsequent to such subdivision or combination or at the record date of such
     dividend or distribution shall simultaneously with the effectiveness of
     such subdivision or combination or immediately after the record date of
     such dividend or distribution be equal to the number of shares of Common
     Stock and Other Securities a holder would have owned and had a right to
     receive as a result of such subdivision, combination, dividend or
     distribution if such holder had actually held of record immediately prior
     to the effectiveness of such subdivision or combination or immediately
     prior to the record date of such dividend or distribution the number of
     shares of Underlying Securities purchasable per Unit immediately prior to
     the effectiveness of such subdivision or combination or the record date of
     such dividend or distribution.

          (b)  REORGANIZATIONS AND RECAPITALIZATIONS.  In case the Company shall
     be reorganized or recapitalized by reclassifying its outstanding Common
     Stock (or Other Securities) without par value to stock with par value,
     then, as a condition of such reorganization or recapitalization, as the
     case may be, immediately after the effective time of such reorganization or
     recapitalization, each Warrantholder shall thereafter have the right to
     purchase, upon the terms and conditions specified herein, the number of
     shares of Underlying Securities per Unit that a holder would have owned and
     had the right to receive as a result of such reorganization or
     recapitalization if such holder had held of record the number of shares of
     Underlying Securities per Unit immediately prior to such reorganization or
     recapitalization.  If any consolidation or merger of the Company with
     another corporation, or the sale of all or substantially all of its assets
     to another corporation, shall be effected in such a way that holders of
     Common Stock and Other Securities shall be entitled to receive stock,
     securities or assets with respect to or in exchange for Common Stock and
     Other Securities, then, as a condition of such consolidation, merger or
     sale, immediately after the effective time of such consolidation, merger or
     sale, the Warrantholders shall thereafter, subject to the last sentence of
     this Subsection, have the right to purchase and receive upon the basis and
     upon the terms and conditions specified in this Warrant Agreement, the
     number of shares of Underlying Securities per Unit that a holder would have
     owned and had a right to receive as a result of such consolidation, merger
     or sale if such holder had actually held of record immediately prior to
     such consolidation, merger or sale the number of shares of Underlying
     Securities purchasable per Unit immediately prior to such consolidation,
     merger or sale.  If the Company is merged into or consolidated with another
     corporation 


                                        5

<PAGE>

     under circumstances where the Company is not the surviving corporation or
     where the Company will be a wholly owned subsidiary of another corporation
     (except where such merger or consolidation is effected merely in order to
     recapitalize or reincorporate the Company), or if the Company sells or
     otherwise disposes of all or substantially all of its property or assets to
     another corporation, all outstanding Warrants may be canceled by the Board
     of Directors of the Company as of the effective date of any such merger,
     consolidation or sale, provided that (i) written notice of such
     cancellation is given to each holder of a Warrant not later than 30 days
     prior to such effective date and (ii) each holder of a Warrant shall have
     the right to exercise such Warrant in full during the said 30-day period
     preceding the effective date of such merger, consolidation or sale.

          (c)  EFFECT OF DISSOLUTION OR LIQUIDATION.  In case the Company shall
     dissolve or liquidate all or substantially all of its assets, all rights
     under this Warrant Agreement and the Warrants shall terminate as of the
     date upon which a certificate of dissolution or liquidation shall be filed
     with the Secretary of State of Wyoming (or, if the Company theretofore
     shall have been merged or consolidated with a corporation incorporated
     under the laws of another state, the state of incorporation on the date
     upon which action of equivalent effect shall have been taken); provided,
     however, that (i) no dissolution or liquidation shall affect the rights
     under Subsection (b) hereof of any Warrantholder and (ii) if the Company's
     Board of Directors shall propose to dissolve or liquidate the Company, each
     Warrantholder shall be given written notice of such proposal at the earlier
     of (i) the time when the Company's shareholders are first given notice of
     the proposal or (ii) the time when notice to the Company's shareholders is
     first required.

          (d)  NOTICE OF CHANGE OF UNDERLYING SECURITIES.  Whenever the number
     of shares of Underlying Securities per Unit or the kind or amount of
     securities or assets purchasable pursuant to the Warrants shall be adjusted
     pursuant to any of the provisions of this Warrant Agreement, or the number
     of shares of Underlying Securities or the kind or amount of securities or
     assets receivable upon conversion of Underlying Securities shall be
     adjusted pursuant to the terms thereof, the Company shall forthwith
     thereafter cause to be sent to each Warrantholder a notice setting forth
     such adjustment and also setting forth in detail the facts requiring such
     adjustments.

7.   FURTHER COVENANTS OF THE COMPANY.

          (a)  DILUTION OR IMPAIRMENTS.  The Company will not, by amendment of
     its certificate of incorporation or through any reorganization, transfer of
     assets, consolidation, merger, dissolution, issue or sale of securities, or
     any other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms of the Warrant or of this Warrant
     Agreement, but will at all times in good faith assist in the carrying out
     of all such terms and in the taking of all such action as may be necessary
     or appropriate in order to protect the rights of the Warrantholders against
     dilution or other impairment.  Without limiting the generality of the
     foregoing, the Company:


                                        6

<PAGE>

               (i)  shall at all times reserve and keep available, solely for
          issuance and delivery upon the exercise of the Warrants, all shares of
          the Underlying Securities from time to time issuable upon the exercise
          of the Warrants and shall use its best efforts to ensure that the par
          value per share, if any, of the Underlying Securities is at all times
          equal to or less than the then effective Purchase Price per share of
          Underlying Securities; and

               (ii)  will take all such action as may be necessary or
          appropriate in order that the Company may validly and legally issue
          fully paid and nonassessable shares of Common Stock and Other
          Securities upon the exercise of the Warrants from time to time
          outstanding.

          (b)  TITLE TO STOCK.  All shares of the Underlying Securities
     delivered upon the exercise of the Warrants shall be validly issued, fully
     paid and nonassessable; each holder of a Warrant shall receive good and
     marketable title to the Underlying Securities, free and clear of all voting
     and other trust arrangements, liens, encumbrances, equities and claims
     whatsoever; and the Company shall have paid all taxes, if any, in respect
     of the issuance thereof.
     
          (c)  LISTING ON SECURITIES EXCHANGES; REGISTRATION.  If the Company at
     any time shall list any Common Stock on any national securities exchange,
     the Company will, at its expense, simultaneously list on such exchange,
     upon official notice of issuance upon the exercise of the Warrants, and
     maintain such listing of, all shares of Common Stock included in the
     Underlying Securities from time to time issuable upon the exercise of the
     Warrants or upon conversion of Underlying Securities, and the Company will
     so list on any national securities exchange, will so register, and will
     maintain such listing of, any Other Securities if and at the time that any
     securities of such class shall be listed on such national securities
     exchange by the Company.  You shall have no right to require the Company to
     register the Warrants.  The Company will use its best efforts to register
     the shares of Common Stock underlying the Warrants and to keep such
     registration statement effective for a period of no less than two years.

          (d)  REMEDIES.  The Company stipulates that the remedies at law of the
     Warrantholder or any holder of Underlying Securities in the event of any
     default or threatened default by the Company in the performance of or
     compliance with any of the terms of this Warrant Agreement or the Warrants
     are not and will not be adequate and that such terms may be specifically
     enforced by a decree of the specific performance of any agreement contained
     herein or in the Warrants or by an injunction against a violation of any of
     the terms hereof or thereof or otherwise.

          (e)  EXCHANGE OF WARRANTS.  Subject to Subsection 3(a) hereof, upon
     surrender or exchange of any Warrant to the Company, the Company at its
     expense will promptly issue and deliver to or upon the order of the holder
     thereof a new Warrant of like tenor, in the name of such holder or as such
     holder (upon payment by such Warrantholder of any applicable transfer
     taxes) may direct, calling in the aggregate for the purchase of the 


                                        7

<PAGE>

     number of shares of the Underlying Securities called for on the face or
     faces of the Warrant or Warrants so surrendered.  The Warrants and all
     rights thereunder are transferable in whole or in part upon the books of
     the Company by the registered holder thereof subject to the provisions of
     Subsection 3(a) hereof, in person or by duly authorized attorney, upon
     surrender of the Warrant, duly endorsed, at the principal office of the
     Company.

          (f)  REPLACEMENT OF WARRANTS.  Upon receipt of evidence reasonably
     satisfactory to the Company of the loss, theft, destruction or mutilation
     of any Warrant, and in the case of any such loss, theft or destruction,
     upon delivery of an indemnity agreement reasonably satisfactory in form and
     amount to the Company, or in the case of such mutilation, upon surrender
     and cancellation of such Warrant, the Company, at the expense of the
     Warrantholder, will execute and deliver, in lieu thereof, a new Warrant of
     like tenor.

          (g)  REPORTING BY THE COMPANY.  The Company agrees that during the
     term of the Warrants and as long as you hold Underlying Securities, it will
     use its best efforts to keep current in the filing of all forms and other
     materials, if any, which it may be required to file with the appropriate
     regulatory authority pursuant to the Exchange Act and all other forms and
     reports required to be filed with any regulatory authority having
     jurisdiction over the Company.

          (h)  FRACTIONAL SHARES.  No fractional shares of Underlying Securities
     are to be issued upon the exercise of any Warrant, but the Company shall
     pay a cash adjustment in respect of any fraction of a share that would
     otherwise be issuable in an amount equal to such fraction multiplied by the
     closing market price per share of Underlying Securities on the day of
     exercise, as determined by the closing bid and asked price regular way on
     the principal national securities exchange on which the Underlying
     Securities is listed or admitted to trading, or if not listed or admitted
     to trading on any national securities exchange, the average of the highest
     reported bid and lowest reported asked price over the preceding 30-day
     period as furnished by the National Quotation Bureau Incorporated;
     provided, however, that if the Underlying Securities are not traded in such
     manner that the quotations referred to herein are available, the market
     price shall be deemed to be the fair market value of such Underlying
     Securities as reasonably determined by the Board of Directors.

8.   OTHER WARRANTHOLDERS.

     The Warrants are issued upon the following terms, to all of which each
holder or owner thereof by the taking thereof consents and agrees: (a) any
person who shall become a transferee, within the limitations on transfer imposed
by Subsection 3(a) hereof, shall take such Warrant subject to the provisions of
Subsection 3(a) hereof and the other provisions hereof and thereupon shall be
authorized to represent himself as absolute owner thereof and, subject to the
restrictions contained in this Warrant Agreement, shall be empowered to transfer
absolute title by endorsement and delivery thereof to a permitted bonafide
purchaser for value; (b) each prior 


                                        8

<PAGE>

taker or owner waives and renounces all of his equities or rights in such
Warrant in favor of each such permitted bonafide purchaser, and each such
permitted bonafide purchaser shall acquire absolute title thereto and to all
rights presented thereby; (c) until such time as the respective Warrant is
transferred on the books of the Company, the Company may treat the registered
holder thereof as the absolute owner thereof for all purposes, notwithstanding
any notice to the contrary; and (d) all references to the words "you" and "your"
in this Warrant Agreement shall be deemed to apply with equal effect to any
person to whom a Warrant has been transferred in accordance with the terms
hereof, and where appropriate, to any person holding shares of the Underlying
Securities.

9.   MISCELLANEOUS.

     All notices, certificates, and other communications from or at the request
of the Company to any Warrantholder shall be mailed by first class, registered,
or certified mail, postage prepaid, to the address set forth herein, to such
address as may have been furnished to the Company in writing by such
Warrantholder, or, if no notice of transfer has been received by the Company, to
the address of the last holder of such Warrant.  This Warrant Agreement and any
of the terms hereof may be changed, waived, discharged, or terminated only
pursuant to Subsection 6(b) hereof or by an instrument in writing signed by the
Company and the holders of Warrants to purchase in excess of 50% of the
Underlying Securities then subject to purchase pursuant to the Warrants.  This
Warrant Agreement shall be construed and enforced in accordance with and
governed by the internal laws of the State of Wyoming.  The headings in this
Warrant Agreement are for purpose of reference only and shall not limit or
otherwise affect any of the terms hereof.  This Warrant Agreement, together with
the forms of instruments annexed hereto as Exhibit A, constitutes the full and
complete agreement of the parties hereto with respect to the subject matter
hereof.

CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

     IN WITNESS WHEREOF, the Company has caused this Warrant Agreement to be
executed as of the 16th day of January, 1996, with an effective date of
December 20, 1995, by its proper corporate officers, thereunto duly authorized.

                                (Borrowing Base)

this "AGREEMENT") by and between 1ST TECH CORPORATION ("1st Tech"), a Delaware
corporation, DARKHORSE SYSTEMS, INCORPORATED ("Darkhorse"), a Delaware

May 20, 1996 ("Effective Date").

PRELIMINARY STATEMENT.  Texas Commerce Bank National Association ("Texas
Commerce") has made loans to 1st Tech Corporation ("Old 1st Tech"), a Texas
Corporation, governed and evidenced by a Credit Agreement between Old 1st Tech
and Texas Commerce dated July 24, 1995, as amended, and the $12,000,000.00 Note
and other Loan Documents referenced in such agreement.  Texas Commerce has made
loans to Darkhorse Systems, Incorporated ("Old Darkhorse"), a Texas Corporation,
governed and evidenced by a $400,000.00 Revolving Promissory Note With Borrowing
Base and Agreement executed by Old Darkhorse and delivered to Texas Commerce
dated January 16, 1996, and the Loan Documents referenced in such note.  The
facilities described in this paragraph and all rights, interests and respective
Loan Documents existing in connection therewith are the "Old Facilities."

In connection with the execution of this Agreement, Guarantor has formed 1st
Tech and Darkhorse (originally incorporated under the respective names Tanisys
Acquisition Corp. and Tanisys Acquisition Corp.  II) to become successors by
merger to Old 1st Tech and Old Darkhorse respectively, on or about the Effective
Date (the "Merger").  Guarantor has requested and Texas Commerce and Bank have
agreed, subject to all terms and conditions of this Agreement, that Bank shall
extend credit to the Borrowers to payoff and replace the Old Facilities.

Each of the parties expressly acknowledges and agrees (i) that the Old
Facilities are and shall remain obligations of Old 1st Tech and Old Darkhorse,
respectively, and any successors, each in accordance with its terms, until
finally paid in full in accordance therewith; (ii) that the transactions
contemplated in the second paragraph of this Preliminary Statement require,
under the terms of the Old Facilities, the consent of Texas Commerce which
consent shall be deemed given upon the effectiveness of this Agreement after the
satisfaction of the Conditions Precedent to this Agreement Generally below; but,
otherwise, such consent has not been given and Texas Commerce is in no way
obligated to give such consent except upon satisfaction of all such Conditions
Precedent to this Agreement Generally.

CONDITIONS PRECEDENT TO THIS AGREEMENT GENERALLY.  This Agreement shall become
effective only upon the occurrence of all the following conditions and events,
all of which must occur on or about the Effective Date, or this Agreement shall
be null and void in all respects:

<PAGE>

1.   All representations and warranties made in this Agreement shall be true.
2.   All conditions precedent set out in section 2.1 and 2.2 shall be satisfied.
3.   All transactions described in the "Pro-forma Consolidation" dated April 18,
     1996 provided to Bank and Texas Commerce by Guarantor shall have been
     consummated.
4.   Without limiting the generality of the preceding condition, the issuance by
     1st Tech of stock in exchange for $2,000,000.00 cash shall have been
     completed.
5.   Borrowing Base Availability after deducting existing balances brought over
     from Old Facilities shall be at least $500,000, for both Borrowers
     combined.
6.   The parties shall execute any further documents, agreements, certificates
     and legal opinions reasonably required by Bank or Texas Commerce to fulfill
     the intent of this Agreement.
7.   Provide 2 year projections of Borrowers and Guarantors Balance Sheet,
     Income Statement, and Cash Flows by July 1, 1996.

there is outstanding and unpaid principal amounts of $2,867,023.66 in Loans
under the Old 1st Tech Credit Agreement and Note; and $188,600.00 in Loans under
the Old Darkhorse Note; all in addition to any accrued and unpaid interest fees
and any other amounts otherwise payable thereunder.

1.   THE LOANS
REVOLVING CREDIT NOTE 1.1.  Subject to the terms and conditions hereof, Bank
agrees to make loans ("LOAN" or "LOANS") to Borrowers from time to time before
the Termination Date, not to exceed at any one time outstanding the lesser of
the Borrowing Base or $6,000,000.00 ("COMMITMENT").  Borrowers may borrow, repay
and reborrow upon a Loan Request in Proper Form submitted by either Borrower.
Loans may only be used to (i) pay off amounts payable under the Old Facilities,
and, thereafter, (ii) finance accounts receivable and inventory from Borrowers'
regular business operations.  Chapter 15 of the Texas Credit Code will not appy
to this Agreement, the Note or any Loan.  The Loans will be evidenced by, and
will bear interest and be payable as provided in, Borrowers' promissory note
dated the Effective Date (together with any and all renewals, extensions,
modifications and replacements thereof and substitutions therefor, the "NOTE").
"TERMINATION DATE" means the earlier of:  (a) June 30, 1998; or (b) the date
specified by Bank pursuant to SECTION 6.1 hereof.

LETTERS OF CREDIT 1.1.A  Bank in its sole absolute discretion may issue sight
draft commercial and/or standby letters of credit up to the day before the
Termination Date for the account of Borrowers and in favor of such Person or
Persons as may be designated by either Borrower upon an application
substantially in the form of Bank's then current application and agreement
therefor or other application acceptable to Bank ("APPLICATION"), duly completed
and executed by either Borrower in Proper Form not less than two (2) Business
Day(s) prior to the date on which the letter of credit is to be issued.  "LETTER
OF CREDIT" means any Letter of Credit issued by Bank upon an Application of
Borrowers.  No Letter of Credit shall have an expiry date later than a date
______ months from the Termination Date.  Letters of Credit may be commercial or
standby.  "L/C OBLIGATIONS" means the sum of (a) the face amount of all
outstanding Letters of Credit less any drawings that have been paid by Borrowers
either with a


                                        2
<PAGE>

Loan or other means acceptable to Bank and (b) any other amounts owing to Bank
under the Applications not already included in (a).  Borrowers will pay a fee in
an amount equal to the greater of: (a) (i) for commercial L/Cs, one percent
(1.0%) per quarter or fraction thereof on the face amount of the Letter of
Credit and (ii) for Standby L/Cs, three percent (3.0%) per annum or fraction
thereof on the face amount of the Letter of Credit; and (b) Bank's minimum fee
in effect on the issue date of the Letter of Credit.  Bank may at any time, but
is not required to, make a Loan without prior notice to Borrowers to pay any
drawing under a Letter of Credit and to pay any L/C Obligation.  Letters of
Credit shall be for the purpose of financing trade credit extended to either
Borrower in its regular course of business.  L/C Obligations shall never exceed
$2,000,000.00 ("LETTER OF CREDIT SUBLIMIT").

BORROWING BASE 1.2:

(a)  The BORROWING BASE on each Business Day is the "Total Availability on
     Accounts Receivable and Inventory" calculated in accordance with the
     Borrowing Base Certificate in Exhibit A, the "Accounts Receivable Loan
     Administration Procedures" delivered by Bank to Borrower and incorporated
     herein by reference as if fully set forth.  Each reference to "Chase
     Manhattan Bank" in Exhibit A shall be deemed a reference to Bank.  The
     Borrowing Base shall include only Accounts receivable of 1st Tech.
(b)  The calculations, definitions and other criteria set out in Exhibit A shall
     be subject to the following definitions and adjustments:
        (i)    "Other" ineligible Accounts means all Accounts not subject to
        Bank's first  and prior lien and security interest and such assets
        deemed from time to time to be, in the sole judgment of the Bank,
        ineligible for purposes of determining the Borrowing Base; Memo A/R and
        Evaluation A/R shall be Ineligible Accounts.  "'Memo' and 'Evaluation'
        A/R" shall include all Accounts of the type typically referred to as
        such by Borrower prior to the Effective Date, and any accounts which do
        not represent payments finally earned or which result from a sale
        subject to product evaluation by the buyer.  Outstanding Loans, interest
        and fees counted against Total Availability on Accounts Receivable and
        Inventory shall use Bank's standard estimation provided by Bank to
        Borrower.
        (ii)   Each Accounts Advance Factor may be increased or decreased by the
        Bank at any time and from time to time upon written notice to Borrower,
        in the reasonable exercise of Bank's sole underwriting discretion.
        Without limiting the generality of the foregoing, Bank shall be deemed
        to have exercised reasonable discretion if it reduces the Accounts
        Advance Factor in reasonable proportion to increased dilution of
        Accounts which Bank believed exceeds 5% of the amount existing at the
        Effective Date of the Agreement.

REQUIRED PAYMENT 1.3  If the unpaid amount of the Loans and L/C Obligations on
any Business Day exceeds the Borrowing Base on such day, Borrowers shall make a
payment on the Note in an amount sufficient to reduce the total unpaid principal
balance of the Note to an amount no greater than the Borrowing Base, such
payment due and payable on the date such excess occurs, to accompany timely
delivery of Borrowers' monthly Borrowing Base Report or Daily Collateral
Certificate, as the case may be.  If the balance on the Note is zero and the


                                        3
<PAGE>

amount of L/C Obligations still exceeds the Borrowing Base, Borrowers will
promptly deliver cash collateral to Bank in an amount sufficient to eliminate
such excess.

FACILITY FEES 1.4  Borrowers will pay the following fees: (i) a Structuring Fee
of $75,000.00, due and payable upon the execution of this Agreement; and (ii) an
Administration Fee of $50,000 per annum payable in installments due on the
Effective Date of this Agreement and the 1st date of each third month
thereafter.  Borrowers authorize Bank in its discretion and without prior notice
to advance against the Commitment and Note to pay these fees when due.

PAST DUE AMOUNTS 1.5  Each amount due to Bank in connection with the Loan
Documents will bear interest from its due date until paid at the Highest Lawful
Rate unless the applicable Loan Document provides otherwise.

2.   CONDITIONS PRECEDENT.
ALL LOANS AND L/C OBLIGATIONS 2.1  Bank is not obligated to make any Loan
unless: (a) Bank has received the following, duly executed and in Proper Form:
(1) a Request for Loan substantially in the form of the sample letter set out in
Exhibit A not later than 11 am Central Time on the date (which shall be a
Business Day) of the proposed Loan, or an Application for Letter of Credit as
provided in section 1.1.A, as the case may be; provided however, Bank may accept
and act upon verbal advance requests received from a Borrower's representative
reasonably believed by Bank to be authorized to make such requests, each such
request to be confirmed in writing in Proper Form; (2) a Borrowing Base Report
within the time required by this Agreement; (3) a Lockbox Processing Agreement
in Proper Form; and (4) such other documents as Bank reasonably may require; (b)
no Event of Default exists; and (c) the making of the Loan is not prohibited by,
or subjects Bank to any penalty or onerous condition under any Legal
Requirement.

FIRST LOAN 2.2  In addition to the matters described in the preceding section,
Bank will not be obligated to make the first Loan unless Bank has received all
of the Loan Documents specified on ANNEX I in Proper Form.

REPRESENTATIONS AND WARRANTIES.  To induce Bank to enter into this Agreement and
to make Loans and create L/C Obligations, each Borrower represents and warrants
as of the Effective Date, the date of each request for a Loan, and each
presentation by any Borrower of any financial information, report, notice and
certificate hereunder, that each of the following statements is and shall remain
true and correct throughout the term of this Agreement:

ORGANIZATION AND STATUS 3.1  Each Borrower and Subsidiary of each Borrower is
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization; has all power and authority to conduct its
business as presently conducted, and is duly qualified to do business and in
good standing in each jurisdiction in which the nature of the business conducted
by it makes such qualification desirable.  No Borrower has any Subsidiary other
than those listed in ANNEX II and each Subsidiary is owned as set forth on ANNEX
II.  If any Borrower is subject to the Texas Revised Partnership Act ("TRPA"),
Borrower agrees that Bank


                                        4
<PAGE>

is not required to comply with Section 3.05(d) of TRPA and agrees that Bank may
proceed directly against one or more partners or their property without first
seeking satisfaction from partnership property.

FINANCIAL STATEMENTS 3.2  All financial statements delivered to Bank are
complete and correct and fairly present, in accordance with generally accepted
accounting principles, consistently applied ("GAAP") (or the other accounting
basis specified herein, if expressly provided for in this Agreement), financial
condition and results of operations as at the dates and for the periods
indicated, on consolidated and consolidating bases.  If this Agreement provides
for audited, reviewed or compiled financial statements, such service shall have
been provided by an independent certified public accountant acceptable to Bank,
and if audited statements are provided such statements shall be certified with
an unqualified opinion in accordance with generally acceptable auditing
standards ("GAAS").  No material adverse change has occurred in the assets,
liabilities, financial condition, business or affairs of any Borrower or any
Subsidiary of any Borrower since the dates of such financial statements.  No
Borrower or Subsidiary of any Borrower is subject to any instrument or agreement
materially and adversely affecting its financial condition, business or affairs.

ENFORCEABILITY 3.3  The Loan Documents are legal, valid and binding obligations
of the Parties enforceable in accordance with their respective terms, except as
may be limited by bankruptcy, insolvency and other similar laws affecting
creditors' rights generally.  The execution, delivery and performance of the
Loan Documents have all been duly authorized by all necessary action; are within
the power and authority of the Parties; do not and will not violate any Legal
Requirement, the Organizational Documents of the Parties or any agreement or
instrument binding or affecting the Parties or any of their respective Property.

COMPLIANCE 3.4  Each Borrower and each Subsidiary of each Borrower has filed all
applicable tax returns and paid all taxes shown thereon to be due, except those
for which extensions have been obtained and those which are being contested in
good faith and for which adequate reserves have been established.  Each Borrower
and each Subsidiary of each Borrower is in compliance with all applicable Legal
Requirements and manages and operates (and will continue to manage and operate)
its business in accordance with good industry practices.  No Borrower or
Subsidiary of any Borrower is in default in the payment of any other
indebtedness or under any agreement to which it is a party.  The Parties have
obtained all consents of and registered with all Governmental Authorities or
other Persons required to execute, deliver and perform the Loan Documents.

LITIGATION 3.5  Except as previously disclosed to Bank in writing, there is no
litigation or administrative proceeding pending or, to the knowledge of any
Borrower, threatened against, nor any outstanding judgment, order or decree
affecting any Borrower or Subsidiary of any Borrower before or by any
Governmental Authority.

TITLE AND RIGHTS 3.5  Each Borrower and Subsidiary of each Borrower has good and
marketable title to its Property, free and clear of any Lien except for Liens
permitted by this Agreement and the other Loan Documents.  Except as otherwise
expressly stated in the Loan


                                        5
<PAGE>

Documents or permitted by this Agreement, the Liens of the Loan Documents will
constitute valid and perfected first and prior Liens on the Property described
therein, subject to no other Liens whatsoever.  Each Borrower and Subsidiary of
each Borrower possesses all permits, licenses, patents, trademarks and
copyrights required to conduct its business.  All easements, rights-of-way and
other rights necessary to maintain and operate each Borrower's Property have
been obtained and are in full force and effect.

REGULATION U; BUSINESS PURPOSE 3.7  None of the proceeds of any Loan will be
used to purchase or carry, directly or indirectly, any margin stock or for any
other purpose which would make this credit a "purpose credit" within the meaning
of Regulation U of the Board of Governors of the Federal Reserve System.  All
Loans will be used for business, commercial, investment or other similar purpose
and not primarily for personal, family, or household use or primarily for
agricultural purposes as such terms are used in Chapter One of the Texas Credit
Code.

ENVIRONMENT 3.8  Each Borrower and Subsidiary of each Borrower have complied
with applicable Legal Requirements in each instance in which any of them have
generated, handled, used, stored or disposed of any hazardous or toxic waste or
substance, on or off its premises (whether or not owned by any of them).  No
Borrower or Subsidiary of any Borrower has any material contingent liability for
non-compliance with environmental or hazardous waste laws.  No Borrower or
Subsidiary of any Borrower has received any notice that it or any of its
Property or operations does not comply with, or that any Governmental Authority
is investigating its compliance with, any environmental or hazardous waste laws.

INVESTMENT COMPANY ACT/PUBLIC UTILITY HOLDING COMPANY ACT 3.9  No Borrower or
Subsidiary of any Borrower is an "investment company" within the meaning of the
Investment Company Act of 1940 or a "holding company" or an "affiliate" of a
"holding company" or a "public utility" within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

STATEMENTS BY OTHERS 3.10  All statements made by or on behalf of any Borrower,
Subsidiary of any Borrower or any other Party in connection with any Loan
Document constitute the joint and several representations and warranties of all
Borrowers hereunder.

NOTICE OF ACCOUNT DEBTORS 3.11  Borrower has sent to each Account Debtor written
instructions in the form previously delivered and approved by Bank, to remit all
payments and remittances in respect to the Accounts directly to the Lockbox.

4.   AFFIRMATIVE COVENANTS.  Each Borrower agrees to do, and if necessary cause
to be done, and cause its Subsidiaries to do, each of the following:

CORPORATE FUNDAMENTALS 4.1  (a) Pay when due all taxes and governmental charges

profits or Property, unless and only to the extent that the same shall be
contested in good faith and adequate reserves have been established therefor,

insurers, on such Property and personnel, in such amounts and against such risks
as is customary with similar Persons or as may be reasonably required by Bank,
and furnish Bank satisfactory evidence thereof promptly upon request.  These
insurance provisions are cumulative of the insurance provisions of the other
Loan Documents.  Bank will be named as a beneficiary, loss payee or additional
insured of such insurance as its interest may appear and Borrowers will provide
Bank with copies of the policies of insurance and a certificate of the insurer
that the insurance required by this section may not be canceled, reduced or
affected in any manner without 30 days' prior written notice to Bank.

(WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES); PROVIDED THAT THE BANK SHALL
RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

SURVIVAL; PARTIES BOUND; TERM OF AGREEMENT 7.5  (a) All representations,
warranties, covenants and agreements made by or on behalf of each Borrower in
connection with


                                       13
<PAGE>

the Loan Documents will survive the execution and delivery of the Loan
Documents; will not be affected by any investigation made by any Person, and
will bind Borrower and the successors, trustees, receivers and assigns of each
Borrower and will benefit the successors and assigns of Bank; PROVIDED that
Bank's agreement to make Loans to Borrowers will not inure to the benefit of any
successor or assign of any Borrower.  Except as otherwise provided herein, the
term of this Agreement will be until the later of the final maturity of the Note
and the full and final payment of all Obligations and all amounts due under the
Loan Documents.  (b) Borrowers shall be entitled to terminate the Commitment by
written notice to Bank, which notice shall become effective as to the accrual of
fees payable hereunder upon the happening of the latest of (i) 30 days after
Bank's receipt of such notice; and (ii) repayment in full of all amounts
outstanding under the Note and otherwise under the Agreement.

DOCUMENTARY MATTERS 7.6  This Agreement may be executed in several identical
counterparts, on separate counterparts; each counterpart will constitute an
original instrument, and all separate counterparts will constitute but one and
the same instrument.  The headings and captions in the Loan Documents have been
included solely for convenience and should not be considered in construing the
Loan Documents.  If any provision of any Loan Document is invalid, illegal or
unenforceable in any respect under any applicable law, the remaining provisions
will remain effective.  The Loans and L/C Obligations and all other obligations
and indebtedness of Borrower to Bank are entitled to the benefit of the Loan
Documents.

EXPENSES AND FEES 7.7  Any provision to the contrary notwithstanding, and
whether or not the transactions contemplated by this Agreement are consummated,
Borrowers agree to pay on demand all out-of-pocket expenses (including, without
limitation, the fees and expenses of counsel for Bank) in servicing and
collection of the Loans and L/C Obligations.  Borrower agrees to pay Bank's
standard (i) Documentation Preparation and Processing Fee for preparation,
negotiation and handling of this Agreement; (ii) lockbox processing fees as
provided for in the separate agreement therefor; (iii) account maintenance fees
for the Collection Account; (iv) any expenses of collection or other expenses
incurred by Bank in connection with the maintenance of the Collection Account,
shall be reimbursed by Borrowers to Bank at customary fee rates charged by the
Bank for the services.  In consideration of Bank's services of collecting the
Accounts hereunder and monitoring and examining the Borrowing Base, Borrowers
agree to pay Bank the Administration Fee provided for in Section 1.4.  Bank may
obtain reimbursement by causing other depository accounts of either Borrower at
Bank to be charged from time to time therefor.  The obligations of Borrowers
under this and the following section will survive the termination of this
Agreement but the accrual of periodic fees accrued during the existence of the
Commitment shall be subject to the termination provisions in Section 7.4.  Each
Borrower authorizes Bank in its discretion and without prior notice to advance
against the Commitment and Note to pay any or all such fees, expenses and other
such Obligations when due.

INDEMNIFICATION 7.8  Each Borrower agrees to indemnify, defend and hold Bank
harmless from and against any and all loss, liability, obligation, damage,
penalty, judgment, claim, deficiency and expense (including interest, penalties,
attorneys' fees and amounts paid in settlement) to which Bank may become subject
arising out of or based upon the Loan Documents, any Loan, or the receipt,
handling, payment and application of the monies received


                                       14
<PAGE>

in connection with the Collection Account, including that resulting from Bank's
own negligence, EXCEPT and to the extent caused by Bank's gross negligence or
willful misconduct.

USURY NOT INTENDED 7.9  Borrowers and Banks intend to conform strictly to
applicable usury laws.  Therefore, the total amount of interest (as defined
under applicable law) contracted for, charged or collected under this Agreement
or any other Loan Document will never exceed the Highest Lawful Rate.  If Bank
contracts for, charges or receives any excess interest, it will be deemed a
mistake.  Bank will automatically reform the Loan Document or charge to conform
to applicable law, and if excess interest has been received, Bank will either
refund the excess to Borrowers or credit the excess on any unpaid principal
amount of the Note or any other Loan Document.  All amounts constituting
interest will be spread throughout the full term of the Loan Document or
applicable Note in determining whether interest exceeds lawful amounts.

RIGHTS OF BORROWER AND BANK 7.10  Bank has not exercised any control, and Bank
shall not exercise any control, over Borrowers in the determination of which of
Borrowers' creditors Borrower will pay or which payments any Borrower will make
in the ordinary course of any Borrower's business.  Each Borrower, alone, shall
exercise such judgment and determination.  Nothing contained herein, however,
shall, in any manner, affect, limit or impair the rights or remedies of Bank
under this Agreement or any other Loan Documents as otherwise provided by
applicable law, whether with regard to realization on the Collateral, rights of
set off, compensation or otherwise.

PARTICIPATION; SETOFF 7.11  Borrowers and Bank acknowledge and agree that Bank,
in Bank's sole discretion, may assign its interest or sell participation(s) in
the Loans and Note to third parties, including without limitation Texas
Commerce, without consent of or notice to Borrowers.  Borrowers and Bank agree
that each such participant shall be treated, to the extent of its pro rata
interest in Borrowers' indebtedness, as if it were a party thereto, and shall be
accorded and is hereby granted the right to setoff against any deposits, credit
balances, or other funds of each Borrower which are or may be in its possession
(without regard to maturity, tenor or other elements of otherwise mutual
indebtedness).

NO COURSE OF DEALING 7.9  NO COURSE OF DEALING BY ANY BORROWER WITH BANK, NO
COURSE OF PERFORMANCE AND NO TRADE PRACTICES OR OTHER EXTRINSIC EVIDENCE OF ANY
NATURE MAY BE USED TO CONTRADICT, VARY, SUPPLEMENT OR MODIFY ANY TERM OF THIS
AGREEMENT.

NOW THEREFORE, in consideration of the premises and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged by
the parties, Borrowers and Bank agree as follows:

1.   The last sentence of Section 1.2(a) is amended to read:  "The Borrowing
Base shall include Accounts of both Borrowers."

2.   Exhibit B is replaced with Exhibit B attached to this Amendment.  The
Borrowing Base certificate included in Exhibit A is replaced with the Borrowing
Base Certificate attached to this Amendment.

3.   Limited Waivers.  Borrowers have reported that as of August 31, 1996 and
September 30, 1996 the Tangible Net Worth of 1st Tech is below the amount agreed
to in the Agreement.  Borrowers have requested and Bank has agreed to waive the
foregoing prior period default, for the specific instances described for those
prior periods only, subject to the terms of this waiver provision.  This waiver
is subject to the conditions and understandings of Borrowers that: (i) no other
waivers are promised by the Bank; (ii) Bank understands the requested waivers to
address all defaults as to covenants, representations and warranties known to
Borrowers as of the Date of this Amendment, Borrowers having represented that in
all other respects no Event of Default has occurred and is continuing; (iii)
Borrowers will not in any way rely upon the any future waiver of any default;
and (iv) any future delay or election not to exercise rights by the Bank shall
not be deemed any waiver of rights.  Bank's rights in the event of a default are
set out in the Agreement, Note and the other Loan Documents.  This provision is
the only evidence of Bank's waiver.

4.   Confirmation of Security Interests.  No security interest, lien, or other
interest granted by Borrowers, any guarantor or other person to Bank is released
or limited in connection with the 

<PAGE>

execution of this Amendment.  Borrowers confirm and ratify each of the liens, 
security interests and other interests granted in each and all security 
agreements executed in connection with, related to, or securing the Credit 
Agreement, each prior amendment and each note and loan heretofore governed by 
the Credit Agreement, each in accordance with its stated terms.  Borrowers 
represent and warrant that each guaranty executed in connection with, related 
to, or securing the Credit Agreement, each prior amendment and each note and 
loan heretofore governed by the Credit Agreement, each in accordance with its 
stated terms.  Borrowers represent and warrant that each guaranty executed in 
connection with, related to, or securing the Credit Agreement, each prior 
amendment and each note and loan heretofore governed by the Credit Agreement, 
remains in force as of the Effective Date of this Amendment, in accordance 
with its stated terms.

5.   Borrowers represent and warrant to Bank that after giving effect to this
Amendment that the representations and warranties set forth in the Credit
Agreement are true and correct on the date hereof as though made on and as of
such date.  Each of the other Loan Documents is in all other respects ratified
and confirmed, and all of the rights, powers and privileges created thereby or
thereunder are ratified, extended, carried forward and remain in full force and
effect except as the Credit Agreement is amended by this Amendment.

6    This Amendment shall become effective as of its Effective Date upon
execution and delivery by each of the parties named in the signature lines
below, and "Agreement" and "Credit Agreement" as used in the Credit Agreement
and this Amendment shall refer to the Credit Agreement as amended by this
Amendment.  This Amendment shall be included within the definition of "Loan
Documents" as used in the Agreement.  This Amendment may be executed in any
number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed shall be deemed an original and all of which
taken together shall constitute but one and the same agreement.

7.   THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES);
PROVIDED THAT THE BANK SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

THIS WRITTEN AMENDMENT AND THE OTHER LOAN DOCUMENTS CONSTITUTE ALL "LOAN
AGREEMENT" AS DEFINED IN SECTION 26.02(a) OF THE TEXAS BUSINESS AND COMMERCE
CODE, AND REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS
OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                             REVOLVING CREDIT NOTE
                                 (this "NOTE")

FOR VALUE RECEIVED, ON OR BEFORE the Termination Date (as defined in the 
Credit Agreement), 1st TECH CORPORATION and DARKHORSE SYSTEMS, INCORPORATED, 
(jointly and severally, "BORROWERS") promise to pay to the order of CHEMICAL 
BANK ("Bank") at its office at 633 Third Avenue, New York, NY 10017 or such 
other location as Bank may designate, in immediately available funds and 
lawful money of the United States of America, the sum of SIX MILLION AND 
NO/100THS UNITED STATES DOLLARS (U.S. $6,000,000.00) or the aggregate unpaid 
amount of all advances hereunder, whichever is lesser, plus interest on the 
unpaid balance outstanding from time to time at a rate per annum equal to the 
lesser of (i) the Stated Rate (as hereinafter defined) from time to time in 
effect or (ii) the Highest Lawful Rate. If the Stated Rate at any time 
exceeds the Highest Lawful Rate, the actual rate of interest to accrue on 
the unpaid principal amount of this Note will be limited to the Highest 
Lawful Rate, but any subsequent reductions in the Stated Rate due to 
reductions in the Prime Rate will not reduce the interest rate payable upon 
the unpaid principal amount of this Note below the Highest Lawful Rate until 
the total amount of interest accrued on this Note equals the amount of 
interest which would have accrued if the Stated Rate had at all times been in 
effect.
     The "STATED RATE" at any time shall be: (i) from the Credit Agreement 
Effective Date through September 30, 1996, a rate equal to the Prime Rate as 
it changed plus 3.0%; and (ii) on and after October 1, 1996, the rate 
indicated by the following chart:

     DETERMINING RATIO            STATED RATE
     ---------------            -----------

     Over 3.0X                  Prime Rate +3.0%
     1.5X to 3.0X               Prime Rate +2.0%
     1.0X top 1.4X              Prime Rate +1.5%
     Less than 1.0X             Prime Rate +1.0%

     The "DETERMINING RATIO" on any date shall be the ratio (determined for 
both Borrowers combined, as of the end of the most recently ended calendar 
month) of (i) Indebtedness to (ii) Annualized EBDITA (Adjusted). Annualized 
EBDITA (Adjusted) shall mean (i) for the first 11 months after the Credit 
Agreement Effective Date, Borrowers' average combined monthly EBDITA 
(Adjusted) (as correctly reported in Borrowers' Compliance Certificates in 
the form of Exhibit C of the Credit Agreement) for all months reported to the 
date the ratio is determined, times twelve; and (ii) thereafter, the sum of 
Borrowers' combined monthly EBDITA (Adjusted) (as correctly reported) for the 
12 months preceding the date the ratio is determined.

     "PRIME RATE" means that rate as determined from time to time by Bank as 
being its prime rate in effect at its principal office in New York City. 
Without notice to Borrowers or any other Person, the Prime Rate shall change 
automatically from time to time as and in the amount by which said prime rate 
shall fluctuate with each such change to be effective as of the date of each 
change in such prime rate. THE PRIME RATE IS A REFERENCE RATE AND DOES NOT 
NECESSARILY REPRESENT THE LOWEST OR BEST RATE. BANK MAY MAKE LOANS AT RATES 
OF INTEREST AT, ABOVE OR BELOW THE PRIME RATE.




<PAGE>


     This Note is the Revolving Credit Note described in Section 1.1 of the 
Credit Agreement (Borrowing Base) between Borrowers and Bank dated as of May 
20, 1996 (as amended, restated and supplemented from time to time, the 
"Credit Agreement" and "Agreement") and sometimes referred to therein as the 
Note. Capitalized terms used in this Note have the meanings used in the 
Agreement.

     Accrued and unpaid interest shall be due and payable monthly, beginning 
on June 30, 1996, and continuing on the last day of each month thereafter and 
at Termination Date when all unpaid principal and accrued and unpaid interest 
shall be finally due and payable. Borrowers must make the payments required 
by Sections 1.3, 1.4 and 1.5 of the Agreement.

     Interest shall be computed on the basis of the actual number of days 
elapsed and a year comprised of 360 days, unless such calculation would 
result in a usurious interest rate, in which case interest will be calculated 
on the basis of a 365 or 266 day year, as applicable.

     All past-due principal and, as permitted by applicable law, interest on 
this Note, shall, at Bank's option, bear interest at the Highest Lawful Rate, 
or if applicable law shall not provide for a maximum nonusurious rate of 
interest, at a rate per annum equal to eighteen percent (18%).

     The unpaid principal balance of this Note at any time shall be the total 
amounts advanced by Bank, less the amount of all payments of principal. 
Absent manifest error, the records of Bank shall be conclusive as to amounts 
owed. Subject to the terms and conditions of the Agreement, Borrowers may use 
all or any part of the credit provided for herein at any time before the 
Termination Date.

     Time is of the essence. Borrowers may at any time pay the full amount or 
any part of this Note without the payment of any premium or fee. At Bank's 
sole option, all payments may be applied to accrued interest, to principal, 
or to both.

     If any Event of Default occurs, then Bank may exercise any and all 
rights and remedies under the Loan Documents, at law, in equity or otherwise.

     Each and all Obligators severally waive notice, demand, presentment for 
payment, notice of nonpayment, notice of intent to accelerate, notice of 
acceleration, protest, notice of protest, and the filing of suit and 
diligence in collecting this Note and all other demands and notices, and 
consent and agree that their liabilities and obligations shall not be 
released or discharged by any or all of the following, whether with or 
without notice to them or any of them, and whether before or after the stated 
maturity hereof: (i) extensions of the time of payment; (ii) renewals; (iii) 
acceptances of partial payments; (iv) releases or substitutions of any 
collateral or any Obligor; and (v) failure, if any, to perfect or maintain 
perfection of any security interest in any collateral. Each Obligor agrees 
that acceptance of any partial payment shall not constitute a waiver.

     Bank and any subsequent owner or holder hereof reserves the right, in 
its sole discretion, without notice to Borrowers, to sell participations or 
assign its interest or both, in all or any part of this Note. For purposes of 
this Note, any assignee or subsequent holder of this Note will be considered 
the "Bank," and each successor to each Borrower will be considered a 
"Borrower."

         "Tech Certificates") shall surrender such Tech Certificates to Tanisys
         or to such agent or agents (the "Exchange Agent") as may be designated
         by Tanisys and shall receive in exchange therefor, upon satisfaction
         of customary delivery requirements and subject to applicable law with
         respect to the exercise of appraisal rights, certificates representing
         the number of whole shares of Tanisys Common Stock into which shares

         representing the cash adjustments for fractional shares, if any.


                                          2

<PAGE>


    (b)  If any certificate evidencing shares of Tanisys Common Stock is to be
         issued in a name other than that in which the Tech Certificate
         surrendered in exchange therefor is registered, it shall be a
         condition of the issuance thereof that the Tech Certificate so
         surrendered shall be properly endorsed and otherwise be in proper form
         for transfer and that the person requesting such exchange pay to the
         Exchange Agent any transfer or other taxes required by reason of the
         issuance of a certificate for shares of Tanisys Common Stock in any
         name other than that of the registered holder of the Tech Certificate
         surrendered or establish to the satisfaction of the Exchange Agent
         that such tax has been paid or is not payable.

    (c)  Until so surrendered and exchanged, each outstanding Tech Certificate
         after the Effective Date shall be deemed for all corporate purposes
         (other than voting and the payment of dividends or other distributions
         as described below) to evidence the number of whole shares of Tanisys
         Common Stock into which the shares of Tech Common Stock represented by
         such Tech Certificates are to be converted pursuant to Section 1.2 of
         this Agreement; provided, however, that no dividends or other
         distributions, if any, in respect to such shares of Tanisys Common
         Stock, declared after the Effective Date and payable to holders of
         record after the Effective Date, shall be paid to the holders of any
         unsurrendered Tech Certificates until such Tech Certificates are
         surrendered.  Subject to the effect, if any, of applicable law, after
         the surrender and exchange of the Tech Certificates, the record
         holders thereof on the date of exchange shall be entitled to receive
         any such dividends or other distributions without interest thereon,
         which theretofore have become payable with respect to the number of
         whole shares of Tanisys Common Stock for which such Tech Certificate
         was exchangeable.  Holders of any unsurrendered Tech Certificates
         shall not be entitled to vote until such unsurrendered Tech
         Certificates are exchanged pursuant to this Section 1.4.  Holders of
         Tech Common Stock who exercise appraisal rights in accordance with the
         provisions of the Texas Business Corporation Act (the "Texas Act")
         shall only be entitled to receive the fair value of their shares of
         Tech Common Stock in accordance with Texas Act.  Such holders shall
         not be entitled to any dividends or other distributions  payable on
         and after the Effective Date to holders of Tanisys Common Stock with
         respect to the shares involved regardless of whether such holders have
         received payment for their shares.

    (d)  Tanisys may, without notice to any person, terminate all exchange
         agencies after thirty (30) days following the Effective Date of the
         Merger, and thereafter all exchanges, payments and notices provided
         for in this Agreement as being made to or by the Exchange Agent shall
         be made to or by Tanisys or its transfer agent.

    Section 1.5  FRACTIONAL SHARES.  No fractional share certificates of
Tanisys Common Stock shall be issued in connection with the conversion of shares
of Tech Common Stock in the Merger, nor will any outstanding fractional share
interest entitle the owner thereof to vote, to receive dividends or to exercise
any other right of a shareholder of Tanisys.  In lieu of any such fractional
shares, any holder of Tech Common Stock shall, upon surrender thereof, be paid
in cash the value of each such fraction, which for this purpose shall be the
product of such fraction multiplied by the


                                          3

<PAGE>

average of the per-share closing prices of Tanisys Common Stock on the Vancouver
Stock Exchange (the "VSE") for the twenty (20) trading days immediately
preceding the date that is ten (10) days prior to the Effective Date, subject to
appropriate adjustment in the event of a stock split, stock dividend or
recapitalization applicable to shares of Tanisys Common Stock held of record on
or before the Effective Date to the extent not reflected in such sale prices.

    Section 1.6  NO FURTHER TRANSFERS.  On the Effective Date, the stock
transfer books of Tech shall be closed, and no further transfer of Tech Common
Stock shall thereafter be made.


                                      ARTICLE 2
                          REPRESENTATIONS AND WARRANTIES OF
                                  TECH AND THE OWNER

assets, liabilities, capitalization, financial position, operations, results of
operations or prospects of Tech.  Tech has heretofore delivered to Tanisys
complete and correct copies of its Articles of Incorporation and By-Laws as such

necessary with respect thereto.  This Agreement has been duly and validly
executed and delivered by Tech and, subject to shareholder approval, constitutes
a legal, valid and binding obligation of Tech, enforceable against it in
accordance with its terms.

is no basis for the assertion against Tech of any such debt, guaranty, liability
or obligation (a) that was not accrued or reserved against in the Tech Financial
Statements; (b) that was incurred after February 29, 1996, other than in the
ordinary course of business; or (c) that in the aggregate has or can reasonably
be expected to have a Material Adverse Effect on Tech.  Tech has in all material

Disclosure Schedule, Tech has not received notice of, and does not know of, any
past, present or future events, conditions, facts, circumstances, activities,
practices, incidents, actions or plans that may interfere with or prevent

ordinances, and any rules or regulations promulgated thereunder, which relate to
the use, ownership or occupancy of the property or the operation of the business
of Tech.

    Section 2.13  PENSION MATTERS.  During the past five years, neither Tech
nor any of its former Subsidiaries has maintained or contributed to any defined
benefit pension plans (as defined in Section 3(2) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) or any multiemployer plans
(as defined in Section 3(37)(A) of ERISA).  Each employee benefit plan (as
defined in Section 3(3) of ERISA) (each, an "Employee Benefit Plan" or "Plan")
maintained for employees of Tech or any of its former Subsidiaries to which Tech
or any of its former Subsidiaries have contributed and any related trust
agreement, annuity contract or any other funding or implementing instrument
complies currently and has complied in the past, as to form, operation and
administration, with the provisions of ERISA, as amended, and all other
applicable laws, rules and regulations and with the Internal Revenue Code of
1986, as amended (the "Code"), where required in order to be tax-qualified under
Section 401(a) or 403(a) and 501(a) of the Code, and no event has occurred that
is reasonably likely to give rise to disqualification of any such Plan under
said Sections.  All necessary governmental approvals for the Employee Benefit
Plans have been obtained; each Employee Benefit Plan that is subject thereto
meets and has met at all times the minimum funding standards of Section 302 of
ERISA, Section 412 of the Code and any other applicable law, and no accumulated
funding deficiency, whether or not waived, exists with respect to any such Plan;
each Employee Benefit Plan that is an employee pension benefit plan (as defined
in Section 3(2)(A) of ERISA) has been duly authorized by the Board of Directors
of Tech and a favorable determination as to the qualification under the Code of
each such employee pension benefit plan has been made by the Internal Revenue
Service.

    Section 2.14  LABOR MATTERS.  Except as set forth on Tech's Disclosure

labor practice.  No unfair labor practice complaint against Tech is pending or
threatened before the National Labor Relations Board.  There is no labor strike,

agreement is pending, and no claim therefor has been asserted.  No collective
bargaining agreement is currently being negotiated by Tech, and Tech has not
experienced any material labor difficulty.  There has not been, and there will
not be, any adverse change in relations with employees of Tech as a result of
any announcement or consummation of the transactions contemplated by this
Agreement.  No employee of Tech is in violation of any term of any employment
contract, or any other contract or agreement with or any restrictive covenant or
any other common law obligation to a former employer relating to the right of
any such employee to be employed by Tech because of the nature of the business
conducted or to be conducted by Tech or to the use of trade secrets or
proprietary information of others, and the employment of Tech's employees does
not subject Tech to liability in connection with such covenants or agreements.
There is neither pending nor threatened Proceedings with respect to any
contract, agreement, covenant or obligation referred to above, nor is there any
basis for asserting the foregoing.

    Section 2.15  INFORMATION FOR FILINGS.  None of the information supplied or
to be supplied by Tech for inclusion, or included, in any documents to be filed
with any regulatory authority in connection with the transactions contemplated

or governmental charge, there is no tax deficiency asserted against Tech, and,

delinquency in the payment of any of the taxes of Tech or, to the best knowledge
of Tech, any proposal for additional taxes or any violation of any federal,
state, local or foreign tax law that could be asserted by any taxing authority,
nor is there any basis for asserting such authority.  There are no tax liens
upon any properties or assets of Tech.  Except as disclosed in Tech's Disclosure
Schedule, no Internal Revenue Service, state or local, audit, investigation or

                                          22

<PAGE>

without further action, be deemed to have fully released Tanisys from any and
all responsibility with respect to a breach of such representations and
warranties unless during such survival period the Owner shall have given Tanisys
notice of the nature and reasonable particulars under the then existing
circumstances of any claimed breach by Tanisys and the basis therefor.  The
obligations, covenants and agreements of Tech, the Owner and Tanisys contained
in this Agreement and any related documents shall survive the Closing.  The
representations, warranties, obligations, covenants, indemnities and agreements
shall not be affected by, and shall remain in full force and effect
notwithstanding, any investigation at any time made by or on behalf of any party
hereto or any information any party may have with respect thereto.

    Section 5.13   INDEMNIFICATION BY TECH AND OWNER AND SECURITY ESCROW.

    (a)  Tech and the Owner shall severally indemnify and hold Tanisys harmless
         from and against, and promptly reimburse Tanisys for any and all loss,
         expense, damage, deficiency, liability or obligation, including
         investigative and settlement costs and attorneys' fees arising out of
         or in connection with any breach of representation or warranty of Tech
         or the Owner contained in Article 2 or Article 4 hereof or in any
         certificate delivered pursuant hereto, regardless of whether Tanisys
         relied upon the truth of such representation or warranty or had any
         knowledge of any breach thereof.  On the Effective Date, fifteen
         percent (15%) of the Merger Consideration of Gary W. Pankonien will be
         escrowed (the "Escrow") with U. S. Trust Company of Texas, N.A. (the
         "Escrow Agent") to secure and satisfy Tanisys' right to
         indemnification hereunder.

    (b)  The Escrow shall be further defined in the Escrow Agreement attached
         hereto as EXHIBIT "C" and shall remain in effect for a period of six
         (6) months from the date of the closing of the Merger Agreement (such
         date, the "Escrow Termination Date").  The Escrow may be maintained
         past the Escrow Termination Date only in the event of litigation
         concerning the Escrow.

    (c)  Upon receipt by Tanisys (the "Indemnified Party") of notice of any
         situation, event or occurrence that might give rise to a claim for
         indemnification of such Indemnified Party against Tech and/or the
         Owner pursuant to this Section 5.13, the Indemnified Party shall give
         prompt written notice thereof to Tech and the Owner (each such party,
         an "Indemnifying Party"), indicating the nature of such
         indemnification.  Failure to give any notice provided under this
         Section 5.13(c) shall in no way be deemed a forfeiture of the
         Indemnified Party's rights to be indemnified under Section 5.13
         provided that such notice is given prior to the Escrow Termination
         Date.  A claim for indemnity may, at the option of the Indemnified
         Party, be asserted as soon as any situation, event or occurrence has
         been noticed by the Indemnified Party, regardless of whether actual
         harm has been suffered or out-of-pocket expenses incurred.

    (d)  Tech's and the Owner's indemnification will be limited to situations,
         events and/or occurrences of which Tanisys provides notice to the
         Owner prior to the Escrow


                                          23

<PAGE>

         Termination Date and to the amount of, and only from shares
         comprising, the Escrow.   Tanisys will not be eligible to obtain any
         indemnification from the Escrow until the aggregate amount of all
         losses, expenses, damages, deficiencies, liabilities and other
         obligations arising out of or in connection with any breach of
         representation or warranty of Tech or the Owner exceeds $10,000 in the
         aggregate and then only for the amount of such excess.  Shares
         released from the Escrow after such time will be returned to the Owner
         in accordance with the terms of the Escrow Agreement.

    Section 5.14   INDEMNIFICATION BY TANISYS.

    (a)  Tanisys shall indemnify and hold the Owner harmless from and against,
         and promptly reimburse the Owner for, any and all loss, expense,
         damage, deficiency, liability or obligation, including investigative
         and settlement costs and attorneys' fees, arising out of or in
         connection with any breach of representation or warranty of Tanisys
         contained in Article 3 hereof, or in any certificate delivered
         pursuant hereto, regardless of whether the Owner relied upon the truth
         of such representation or warranty or had any knowledge of any breach
         thereof.

    (b)  Upon receipt by the Owner (the "Indemnified Party") of notice of any
         situation, event or occurrence that might give rise to a claim for
         indemnification of such Indemnified Party against Tanisys pursuant to
         this Section, the Indemnified Party shall give prompt written notice
         thereof to Tanisys indicating the nature of such indemnification.  A
         claim for indemnity may, at the option of the Indemnified Party, be
         asserted as soon as any situation, event or occurrence has been
         noticed by the Indemnified Party regardless of whether actual harm has
         been suffered or out-of-pocket expenses incurred.

    Section 5.15  RESALE LIMITATIONS.  Tech and the Owner (and future Owners)
agree to certain resale restrictions and further agree to advise future Owner(s)
of the resale restrictions imposed by the VSE and federal securities laws on
shares of Tanisys Common Stock received by them pursuant to the Merger, and will
sign, and will cause each future owner to sign, a Restricted Stock Investment
Letter stating that such Affiliate is aware of such restrictions and as set
forth in Section 6.3(h) herein.

    Section 5.16  REGISTRATION STATEMENT.  In the event Tanisys elects to file
a Registration Statement on Form S-1 or S-3 with the Securities and Exchange
Commission ("SEC") and is requested to do so by Gary W. Pankonien ("Pankonien"),
Tanisys agrees to register for sale up to 100,000 shares of the Merger
Consideration for Pankonien and to cause such Registration Statement to become
effective as promptly as practical thereafter and to maintain the effectiveness
of such Registration Statement until the earlier of the sale of the shares
registered thereby or the second anniversary of the Effective Date.  Tanisys
shall be permitted to include on any such Registration Statement shares of the
Tanisys Common Stock to be issued (i) by the company or by stockholders with
registration rights directly to the public and/or to institutional investors for
cash, or (ii) by stockholders receiving registration rights in connection with
any acquisitions to be


                                          24

completed by Tanisys prior to, simultaneously with, or subsequent to, completion
of the Merger.  Tanisys shall also take any action required to be taken under
any applicable state blue sky or securities laws in connection with the issuance
of the shares of the Tanisys Common Stock to be issued as set forth in this
Agreement or the listing of such shares of the Tanisys Common Stock on the
NASDAQ National Market System, subject to official notice of issuance. Pankonien
shall furnish to Tanisys, in writing, all information and covenants concerning
Tech, the other holders of the Tech Common Stock and the proposed methods of
sale or other disposition of the registered shares as Tanisys, any underwriter,
the SEC and/or any state or other regulatory authority may request in connection
with the registration of any shares or any action required by Tanisys.
Pankonien will cooperate with Tanisys and use reasonable efforts to assist
Tanisys in, and Tanisys will bear all costs and expenses (including its legal,
accounting and printing costs and filing fees payable to the SEC and other
governmental bodies) related to, the preparation and filing of the Registration
Statement and all other necessary documentation and to obtain all permits,
consents, approvals and authorizations of all third parties and governmental
bodies necessary to effect the registration of the 100,000 shares of the Merger
consideration on the Registration Statement.  Pankonien agrees to execute,
deliver and/or file with or supply to Tanisys, any underwriter, the SEC and/or
any state or other regulatory authority such information as is necessary to
carry out the provisions of this Section or to effect the registration or
qualification of the shares under applicable securities laws and regulations of
any jurisdiction and such information as Tanisys may reasonably require to
ensure that the transfer or disposition of the registered shares is not in
violation of any applicable securities laws.  The parties shall also enter into
an agreement to provide reciprocal indemnities to the other party for
representations made in such Registration Statement and related documents.
Pankonien further agrees to furnish to Tanisys not later than every thirty (30)
days after the date of effectiveness of the Registration Statement a report of
the number of registered shares sold during such thirty (30)-day period and to
cancel any orders to sell and/or to reverse any sales of registered shares which
orders and/or sales, in Tanisys' opinion, based upon the opinion of legal
counsel experienced in securities law matters were effected in violation of
applicable federal or state securities laws.  At its expense, Tanisys will
furnish to Pankonien such number of copies of such Registration Statement and of
each amendment and supplement thereto (in each case, including all Exhibits) and
such number of copies of the prospectus included in such Registration Statement
as Pankonien shall request.  Tanisys will notify Pankonien of any shares covered
by such Registration Statement (i) at any time when a prospectus relating
thereto is required to be delivered under applicable securities laws, (ii) of
the happening of any event as a result of which the prospectus included in such
Registration Statement as then in effect includes an untrue statement of
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances then existing, or (iii) of any other occurrence which, under
applicable securities laws, requires the prospectus to be revised or updated
(and upon receipt of such notice and until a supplemented or amended prospectus
is available, Pankonien will cease to offer or  to sell any shares covered by
the Registration Statement and will return all copies of the prospectus to
Tanisys if requested to do so by Tanisys and will not sell any of the shares
until provided with a current prospectus and notice from Tanisys that it may
resume its selling efforts).  Upon the occurrence of any of the events described
in clauses (ii) or (iii) of the preceding sentence, Tanisys agrees to use its
best efforts to take all necessary actions to revise or update the prospectus as
promptly as practical to the extent necessary for selling efforts to resume.

                 AMENDMENT NO. 1 TO AGREEMENT AND PLAN OF MERGER


     This Amendment No. 1 amends that certain Agreement and Plan of Merger dated
April 9, 1996 (the "Agreement"), by and among Tanisys Technology, Inc.

     1.   Section 1.2, CONVERSION OF SHARES, is hereby amended in its entirety
to read as follows:

          "Section 1.2 CONVERSION OF SHARES. Upon the latter of the
     issuance of a Certificate of Merger by the Secretary of State of the
     State of Delaware or the issuance of a Certificate of Merger by the
     Secretary of State of the State of Texas (the "Effective Date"), the
     issued and outstanding shares of common stock, no par value per share,
     of Tech (the "Tech Common Stock"), subject to the fulfillment of the
     conditions precedent set forth under Article 6 herein, and the
     applicable statutory provisions with respect to appraisal rights, any
     applicable withholding requirements and adjustment as herein provided,
     shall be converted into and become, and there shall be paid and
     issued, in exchange for the Tech Common Stock an aggregate of
     2,950,000 shares of Tanisys common stock, no par value per share (the
     "Tanisys Common Stock"), such that each share of Tech Common Stock
     outstanding on the Effective Date, not to exceed 2,950,000 shares of
     Tech Common Stock in the aggregate, is exchanged for one (1) share
     (the "Exchange Ratio") of Tanisys Common Stock, with any excess shares
     of Tech Common Stock resulting in a reduction in the per-share
     Exchange Ratio. As used in this Agreement, "Merger Consideration"
     shall mean the aggregate of 2,950,000 shares of Tanisys Common Stock
     exchanged for Tech Common Stock in the Merger at the Exchange Ratio. 
     Each share of Tech Common Stock held in the treasury of Tech or by a
     wholly-owned subsidiary of Tech shall be cancelled as of the Effective
     Date and no portion of the Merger Consideration shall be payable with
     respect thereto. The Merger Consideration shall be reduced by the
     amount otherwise payable or issuable to holders of Tech who exercise
     dissenters' rights, if any, in connection with the Merger based upon
     such shareholders' ownership of Tech Common Stock outstanding on the
     Effective Date. The Exchange Ratio shall be subject to appropriate
     adjustment in the event of a stock split, stock dividend or
     recapitalization subsequent to the date of this Agreement applicable
     to shares of Tech Common Stock or Tanisys Common Stock held of record
     on or before the Effective Date."

     2.   Section 2.3, CAPITALIZATION, is hereby amended in its entirety to read

          "Section 2.3 CAPITALIZATION. The authorized capital stock of
     Tech consists of 10,000,000 shares of Tech Common Stock, no par value,
     of which, as of the date hereof, 1,650,000 shares of Tech Common Stock
     are validly issued and outstanding, 

<PAGE>

     fully paid and nonassessable, and upon the Effective Date, there will
     be no more than 2,950,000 shares of Tech Common Stock validly issued
     and outstanding, fully paid and nonassessable.  As of the date of this
     Agreement, there are no shares of Tech Common Stock held in the treasury
     of Tech and there are no other shares of the capital stock of Tech. As of
     the date hereof, except as disclosed in Tech's Disclosure Schedule, there
     are no outstanding options, warrants, rights or other commitments to issue
     or sell any shares of capital stock or any securities or obligations
     convertible into or exchangeable for, or giving any person any right
     to acquire from Tech, any shares of its capital stock. No shares of
     Tech's capital stock have been issued in violation of any preemptive
     rights or applicable federal or state securities laws. Except
     pursuant to the Texas Act, there are no restrictions, including but
     not limited to self-imposed restrictions, on the retained earnings of
     Tech or on the ability of Tech to declare and pay dividends. There
     are no outstanding obligations of Tech to repurchase, redeem or
     otherwise acquire any capital stock or other securities of Tech."

     3.   Section 4.1, TITLE TO SHARES, is hereby amended in its entirety to
read as follows:
               "Section 4.1 TITLE TO SHARES. Immediately prior to the
     Closing, the Owner(s) shall be the lawful Owner(s) and holder(s) of an
     aggregate of no more than 2,950,000 shares of Tech Common Stock and,
     on the Effective Date, shall hold all such shares free and clear of
     any encumbrances or liens."

     4.   Section 6.1(f), TECH'S EQUITY INFUSION, is hereby amended in its
entirety to ready as follows:

          "(f) TECH'S EQUITY INFUSION. Prior to the Closing as called for
     herein, Tech shall have caused to be sold that number of shares of the
     Tech Common Stock that would comply with the Exchange Ratio of Section
     1.2 herein for no less than $2,300,000 cash. Such purchasers of
     equity shall execute all documents deemed necessary by counsel of
     Tanisys at or prior to the Closing, including but not limited to those
     representations and warranties as set forth in Article 4 and
     restrictions as set forth in Section 5.15."

     5.   All references to "3,100,000" shares of Tech Common Stock or Tanisys
Common Stock in documents relating to the Agreement, including but not limited
to the exhibits and schedules attached to the Agreement, are hereby changed to
"2,950,000."

     6.   All undefined capitalized terms used in this Amendment shall have the
meanings set forth in the Agreement.

     7.   All terms and conditions of the Agreement and related documents not

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

     Pursuant to the provisions of Article 262 of the Delaware Corporation Act
(the "Delaware Act"), the undersigned domestic corporation and foreign
corporation adopt the following Articles of Merger ("Articles of Merger"), this
31st day of May, 1996, for the purpose of effecting a merger between TANISYS

Article 251 of the Delaware Act.  Tanisys Acquisition and Tech are sometimes

becoming the surviving corporation in accordance with the Agreement and these

     The respective Boards of Directors of Tanisys Acquisition and Tech deem it
advisable and in the best interests of each such corporation and their
respective shareholders that Tech

Agreement, and they have accordingly adopted resolutions approving the 
Agreement and these Articles of Merger, and the Agreement and these Articles 
of Merger have been approved by the required vote of the shareholders of each

name "Tanisys Acquisition Corp."  The Merger shall be pursuant to the provisions
of and with the effect provided in the Delaware Act and the Texas Business
Corporation Act (the "Texas Act").

                       Manner and Basis of Converting Shares

     4.1. On the Effective Date of the Merger, subject to Section 4.7 hereof,
each share of Tanisys Acquisition Common Stock issued and outstanding
immediately prior to the Effective Date of the Merger (other than Tanisys
Acquisition Appraisal Shares (as hereinafter defined), all of which shall be
cancelled) shall continue to remain outstanding and unchanged.  "Tanisys
Acquisition Appraisal Shares" are those shares of Tanisys Acquisition Common
Stock as to which shareholders of Tanisys Acquisition have properly exercised
and perfected their right to dissent and receive the fair value thereof in
accordance with Article 262 of the Delaware Act.  Also on the Effective Date of
the Merger, subject to Sections 4.3 and 4.7 hereof and adjustment as provided
herein, each share of Tech Common Stock issued and outstanding immediately prior
to the Effective Date of the Merger (other than Tech Appraisal Shares (as
hereinafter defined), all of which shares shall be cancelled), not to exceed
2,950,000 shares of Tech Common Stock in the aggregate, shall, by virtue of the
Merger and without any action on the part of the holder thereof, thereupon be
converted into and become, in exchange for each share of Tech Common Stock, one
(1) share (the "Exchange Ratio") of Tanisys common stock, no par value per share
(the "Tanisys Common Stock"), with any excess shares of Tech Common Stock
resulting in a reduction in the per-share Exchange Ratio.  In the event that
Tech has less than 2,950,000 shares of Tech Common Stock outstanding on the
Effective Date of the Merger, the Exchange Ratio shall be proportionally
increased.  Each share of Tech Common Stock held in the treasury of Tech or by a
wholly-owned subsidiary of Tech shall be cancelled as of the Effective Date of
the Merger, and no portion of the Merger Consideration (as hereinafter defined)
shall be payable with respect thereto.  As used in these Articles of Merger,
"Merger Consideration" shall mean the aggregate of 2,950,000 shares of Tanisys
Common Stock exchanged for Tech Common Stock in the Merger at the Exchange
Ratio.  The Merger Consideration shall be reduced by the amount otherwise
payable or issuable to holders of Tech who exercise dissenters' rights in
connection with the Merger based upon such shareholders' ownership of Tech
Common


                                        3
<PAGE>


Stock outstanding on the Effective Date of the Merger.  The Exchange Ratio 
shall be subject to appropriate adjustment in the event of a stock split, 
stock dividend or recapitalization subsequent to the date of the Agreement 
applicable to shares of Tech Common Stock or Tanisys Common Stock held of 
record on or before the Effective Date of the Merger.  "Tech Appraisal 
Shares" are those shares of Tech Common Stock as to which shareholders have 
properly exercised and perfected their right to dissent and to receive the 
fair value thereof in accordance with Articles 5.11, 5.12 and 5.13 of the 
Texas Act.

     4.2. After the Effective Date of the Merger, each holder of record of an 
outstanding certificate or certificates representing shares of Tech Common 
Stock shall surrender such certificate or certificates to Tanisys or to such 
agent or agents as shall be appointed by Tanisys (the "Exchange Agent") and 
shall be entitled to receive in exchange therefor (except to the extent such 
certificate or certificates represent Tech Appraisal Shares) a certificate or 
certificates representing the number of whole shares of Tanisys Common Stock 
into which the shares of Tech Common Stock theretofore represented by the 
certificate or certificates so surrendered shall have been converted, 
together with a check representing the cash adjustments for fractional 
shares, if any.  Except as otherwise provided herein, each share of Tech 
Common Stock issued and outstanding immediately prior to the Effective Date 
of the Merger shall on and after the Effective Date of the Merger be deemed 
for all corporate purposes to evidence ownership of the number of shares of 
Tanisys Common Stock into which such shares have been converted.  Until 
certificates representing shares of Tech Common Stock shall be surrendered 
and exchanged for certificates representing shares of Tanisys Common Stock, 
no dividend or other distributions, if any, payable to holders of record of 
Tanisys Common Stock as of any date subsequent to the Effective Date of the 
Merger shall be paid to the holders of such outstanding certificates of Tech 
Common Stock.  Holders of unsurrendered certificates for shares of Tech 
Common Stock shall not be entitled to vote until such unsurrendered 
certificates for shares of Tech Common Stock are exchanged pursuant to this 
Section 4.2.  Upon surrender and exchange of such outstanding certificates of 
Tech Common Stock and subject to the effect, if any, of applicable law, there 
shall be paid to the record holders of the certificates issued in exchange 
therefor, the amount, without interest thereon, of dividends and other 
distributions, if any, which has become payable after the Effective Date of 
the Merger with respect to the number of whole shares of Tanisys Common Stock 
represented thereby.  Immediately prior to the Effective Date of the Merger, 
all outstanding stock options or rights to purchase Tech Common Stock, if 
any, shall be surrendered by the respective holders thereof and shall 
terminate and be cancelled and shall have no further force and effect 
whatsoever.

     4.3. Tanisys shall not be required to issue, and no certificates shall be
issued, for a fraction of a share of Tanisys Common Stock to any shareholder of
Tanisys in respect of fractional interests, but in lieu thereof each such holder
of shares of Tanisys Common Stock who would otherwise have been entitled to a
fraction of a share of Tanisys Common Stock, upon compliance with Section 4.2
hereof, shall be paid cash equal to such fraction multiplied by the average of
the per-share closing prices of Tanisys Common Stock on the Vancouver Stock
Exchange for the twenty (20) trading days immediately preceding the date that is
ten (10) days prior to the Effective Date of the Merger, subject to appropriate
adjustment in the


                                        4
<PAGE>


event of a stock split, stock dividend or recapitalization applicable to 
shares of Tanisys Common Stock held of record on or before the Effective Date 
of the Merger to the extent not reflected in such sales prices.

     4.4. If any certificate evidencing shares of Tanisys Common Stock is to be
issued in a name other than that in which the Tech certificate surrendered in
exchange therefor is registered, it shall be a condition of the issuance thereof
that the certificate so surrendered shall be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange pay to
Tanisys or the Exchange Agent any transfer or other taxes required by reason of
the issuance of a certificate for shares of Tanisys Common Stock in any name
other than that of the registered holder of the certificate surrendered or
establish to the satisfaction of Tanisys or the Exchange Agent that such tax has
been paid or is not payable.

     4.5. Tanisys may, without notice to any person, terminate all exchange
agencies after thirty (30) days following the Effective Date of the Merger, and
thereafter all exchanges, payments and notices provided for in these Articles of
Merger as being made to or by the Exchange Agent shall be made to or by Tanisys
or its transfer agent.

     4.6. The holder of a certificate or certificates representing shares of
Tech Common Stock issued and outstanding immediately prior to the Effective Date
of the Merger shall have no rights with respect to such shares other than to
exercise and perfect their right to dissent to the Merger and to receive the
fair value of such shares in the manner provided by Articles 5.11, 5.12 and 5.13
of the Texas Act or surrender such certificate or certificates pursuant to
Section 4.2 hereof.  The holder of a certificate or certificates representing
shares of the Tanisys Acquisition Common Stock issued and outstanding prior to
the Effective Date of the Merger shall have no rights with respect to such
shares other than to exercise and perfect their right to dissent to the Merger
and to receive the fair value of such shares in the manner provided by Article
262 of the Delaware Act.

     4.7. If the holder of any shares of Tech Common Stock issued and
outstanding immediately prior to the Effective Date of the Merger shall become
entitled to receive payment for such shares in accordance with the applicable
provisions of Articles 5.11, 5.12 and 5.13 of the Texas Act, then such payment
shall be in lieu of the conversion provided in Section 4.1 hereof and shall be
made by the Surviving Corporation.  Tech shall give Tanisys Acquisition and
Tanisys prompt notice upon receipt of any written objections to the Merger or
claims of appraisal rights and shall not without prior written consent of
Tanisys Acquisition and Tanisys make any payment with respect to, or settle or
offer to settle, any such objection or claim.  If the holder of any shares of
Tanisys Common Stock issued and outstanding immediately prior to the Effective
Date of the Merger shall become entitled to receive payment for such shares in
accordance with the applicable provisions of Article 262 of the Delaware Act,
then such payment shall be made by the Surviving Corporation.

         Rights and Duties of Tanisys Acquisition as the Surviving Corporation

     5.1. On the Effective Date of the Merger, the separate existence of Tech
shall cease for all purposes, and Tech shall be merged with and into Tanisys

public as well as of a private nature, and shall be subject to all the

without further act or deed.  The title to any real estate vested by deed or
otherwise, in either of the Constituent Corporations, shall not revert or be in
any way impaired by reason of the Merger.

     5.2. On the Effective Date of the Merger, the Surviving Corporation shall
also be responsible and liable and subject to all restrictions, liabilities,

claim existing or action or proceeding pending by or against any of the
Constituent Corporations may be prosecuted as if the Merger had not taken place
or the Surviving Corporation had been substituted in its place.  Neither the
rights of creditors nor any liens upon the property of any of the Constituent
Corporations shall be impaired by the Merger, and such rights and liens shall
attach to the Surviving Corporation, and may be enforced against it to the same
extent as if the Merger had not taken place.  If at any time the Surviving
Corporation shall consider or be advised that any further assignment or
assurances in law or any things are necessary or desirable to vest in the
Surviving Corporation, according to the terms hereof, the title of any property
or rights of Tech, the last acting officers and directors of Tech, as the case

                            TANISYS ACQUISITION CORP.
                            (a Delaware corporation)
_______________________________________________________________________________
_______________________________________________________________________________

     Pursuant to the provisions of Article 5.04 of the Texas Business
Corporation Act (the "Texas Act"), the undersigned domestic corporation and
foreign corporation adopt the following Articles of Merger ("Articles of
Merger"), this 31st day of May, 1996, for the purpose of effecting a merger

Acquisition"), and 1ST TECH CORPORATION, a Texas corporation ("Tech"), in
accordance with the provisions of Article 5.01 of the Texas Act.  Tanisys
Acquisition and Tech are sometimes referred to herein as the "Constituent
Corporations."

                                   RECITALS

     Tanisys Acquisition is a corporation duly organized and existing under the

     Tanisys Technology, Inc., a Wyoming corporation and holder of all of the

and Tech, among others, have entered into an Agreement and Plan of Merger, dated

with and into Tanisys Acquisition (the "Merger"), with Tanisys Acquisition
becoming the surviving corporation in accordance with the Agreement and these
Articles of Merger.

     The respective Boards of Directors of Tanisys Acquisition and Tech deem it
advisable and in the best interests of each such corporation and their
respective shareholders that Tech

<PAGE>

be merged with and into Tanisys Acquisition as provided herein and in the 
Agreement, and they have accordingly adopted resolutions approving the 
Agreement and these Articles of Merger, and the Agreement and these Articles 
of Merger have been approved by the required vote of the shareholders of each 
Constituent Corporation.

     Therefore, in consideration of the premises and the mutual covenants and
agreements herein contained, the parties hereto covenant and agree to the
following Plan of Merger:


                                   ARTICLE 1.

                                   The Merger

     On the Effective Date of the Merger (as defined in Article 6 hereof), Tech
shall be merged with and into Tanisys Acquisition, which as the surviving
corporation is sometimes referred to herein as the "Surviving Corporation."  The
separate existence and corporate organization of Tech shall cease upon the
Effective Date of the Merger, and thereafter Tanisys Acquisition shall continue
as the Surviving Corporation under the laws of the State of Delaware under the
name "Tanisys Acquisition Corp., d/b/a 1st Tech."  The Merger shall be pursuant
to the provisions of and with the effect provided in the Texas Act and the
Delaware Corporation Act (the "Delaware Act").


                                   ARTICLE 2.

                      Articles of Incorporation and Bylaws

     2.1. On the Effective Date of the Merger, the Articles of Incorporation of
Tanisys Acquisition, as in effect immediately prior to the Effective Date of the
Merger, shall be the Articles of Incorporation of the Surviving Corporation,
until duly amended in accordance with law and such Articles of Incorporation.

     2.2. On the Effective Date of the Merger, the Bylaws of Tanisys
Acquisition, as in effect immediately prior to the Effective Date of the Merger,
shall be the Bylaws of the Surviving Corporation, until the same shall
thereafter be altered, amended or repealed in accordance with law, the Articles
of Incorporation of the Surviving Corporation and such Bylaws.


                                   ARTICLE 3.

                             Directors and Officers

     3.1.  The number of directors comprising the Board of Directors of the
Surviving Corporation shall be one (1), and such director, who shall serve until
his successor has been

                                       2

<PAGE>

duly elected and qualified or until his resignation, death or removal, in 
accordance with law, the Articles of Incorporation and the Bylaws of the 
Corporation, shall be Mark C. Holliday.

     3.2.  The officers of the Surviving Corporation after the Effective Date of
the Merger, who shall serve in the capacity listed opposite their respective
names until their successors have been duly elected and qualified or until their
resignation, death or removal, in accordance with law, the Articles of
Incorporation and Bylaws of the Surviving Corporation, shall be as follows:

     Mark C. Holliday                   President
     Keith D. Thatcher                  Vice President, Chief Financial Officer
                                          and Corporate Treasurer
     Lynne Reilly                       Corporate Secretary


                                   ARTICLE 4.

                     Manner and Basis of Converting Shares

     4.1. On the Effective Date of the Merger, subject to Section 4.7 hereof,
each share of Tanisys Acquisition Common Stock issued and outstanding
immediately prior to the Effective Date of the Merger (other than Tanisys
Acquisition Appraisal Shares (as hereinafter defined), all of which shall be
cancelled) shall continue to remain outstanding and unchanged.  "Tanisys
Acquisition Appraisal Shares" are those shares of Tanisys Acquisition Common
Stock as to which shareholders of Tanisys Acquisition have properly exercised
and perfected their right to dissent and receive the fair value thereof in
accordance with Article 262 of the Delaware Act.  Also on the Effective Date of
the Merger, subject to Sections 4.3 and 4.7 hereof and adjustment as provided
herein, each share of Tech Common Stock issued and outstanding immediately prior
to the Effective Date of the Merger (other than Tech Appraisal Shares (as
hereinafter defined), all of which shares shall be cancelled), not to exceed
2,950,000 shares of Tech Common Stock in the aggregate, shall, by virtue of the
Merger and without any action on the part of the holder thereof, thereupon be
converted into and become, in exchange for each share of Tech Common Stock, one
(1) share (the "Exchange Ratio") of Tanisys common stock, no par value per share
(the "Tanisys Common Stock"), with any excess shares of Tech Common Stock
resulting in a reduction in the per-share Exchange Ratio.  In the event that
Tech has less than 2,950,000 shares of Tech Common Stock outstanding on the
Effective Date of the Merger, the Exchange Ratio shall be proportionally
increased.  Each share of Tech Common Stock held in the treasury of Tech or by a
wholly-owned subsidiary of Tech shall be cancelled as of the Effective Date of
the Merger, and no portion of the Merger Consideration (as hereinafter defined)
shall be payable with respect thereto.  As used in these Articles of Merger,
"Merger Consideration" shall mean the aggregate of 2,950,000 shares of Tanisys
Common Stock exchanged for Tech Common Stock in the Merger at the Exchange
Ratio.  The Merger Consideration shall be reduced by the amount otherwise
payable or issuable to holders of Tech who exercise dissenters' rights in
connection with the Merger based upon such shareholders' ownership of Tech
Common

                                       3

Stock outstanding on the Effective Date of the Merger.  The Exchange
Ratio shall be subject to appropriate adjustment in the event of a stock split,
stock dividend or recapitalization subsequent to the date of the Agreement
applicable to shares of Tech Common Stock or Tanisys Common Stock held of record
on or before the Effective Date of the Merger.  "Tech Appraisal Shares" are
those shares of Tech Common Stock as to which shareholders have properly
exercised and perfected their right to dissent and to receive the fair value
thereof in accordance with Articles 5.11, 5.12 and 5.13 of the Texas Act.

     4.2. After the Effective Date of the Merger, each holder of record of an
outstanding certificate or certificates representing shares of Tech Common Stock
shall surrender such certificate or certificates to Tanisys or to such agent or
agents as shall be appointed by Tanisys (the "Exchange Agent") and shall be
entitled to receive in exchange therefor (except to the extent such certificate
or certificates represent Tech Appraisal Shares) a certificate or certificates
representing the number of whole shares of Tanisys Common Stock into which the
shares of Tech Common Stock theretofore represented by the certificate or
certificates so surrendered shall have been converted, together with a check
representing the cash adjustments for fractional shares, if any.  Except as
otherwise provided herein, each share of Tech Common Stock issued and
outstanding immediately prior to the Effective Date of the Merger shall on and
after the Effective Date of the Merger be deemed for all corporate purposes to
evidence ownership of the number of shares of Tanisys Common Stock into which
such shares have been converted.  Until certificates representing shares of Tech
Common Stock shall be surrendered and exchanged for certificates representing
shares of Tanisys Common Stock, no dividend or other distributions, if any,
payable to holders of record of Tanisys Common Stock as of any date subsequent
to the Effective Date of the Merger shall be paid to the holders of such
outstanding certificates of Tech Common Stock.  Holders of unsurrendered
certificates for shares of Tech Common Stock shall not be entitled to vote until
such unsurrendered certificates for shares of Tech Common Stock are exchanged
pursuant to this Section 4.2.  Upon surrender and exchange of such outstanding
certificates of Tech Common Stock and subject to the effect, if any, of
applicable law, there shall be paid to the record holders of the certificates
issued in exchange therefor, the amount, without interest thereon, of dividends
and other distributions, if any, which has become payable after the Effective
Date of the Merger with respect to the number of whole shares of Tanisys Common
Stock represented thereby.  Immediately prior to the Effective Date of the
Merger, all outstanding stock options or rights to purchase Tech Common Stock,
if any, shall be surrendered by the respective holders thereof and shall
terminate and be cancelled and shall have no further force and effect
whatsoever.

     4.3. Tanisys shall not be required to issue, and no certificates shall be
issued, for a fraction of a share of Tanisys Common Stock to any shareholder of
Tanisys in respect of fractional interests, but in lieu thereof each such holder
of shares of Tanisys Common Stock who would otherwise have been entitled to a
fraction of a share of Tanisys Common Stock, upon compliance with Section 4.2
hereof, shall be paid cash equal to such fraction multiplied by the average of
the per-share closing prices of Tanisys Common Stock on the Vancouver Stock
Exchange for the twenty (20) trading days immediately preceding the date that is
ten (10) days prior to the Effective Date of the Merger, subject to appropriate
adjustment in the 

                                       4

<PAGE>

event of a stock split, stock dividend or recapitalization applicable to 
shares of Tanisys Common Stock held of record on or before the Effective Date 
of the Merger to the extent not reflected in such sales prices.

     4.4. If any certificate evidencing shares of Tanisys Common Stock is to be
issued in a name other than that in which the Tech certificate surrendered in
exchange therefor is registered, it shall be a condition of the issuance thereof
that the certificate so surrendered shall be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange pay to
Tanisys or the Exchange Agent any transfer or other taxes required by reason of
the issuance of a certificate for shares of Tanisys Common Stock in any name
other than that of the registered holder of the certificate surrendered or
establish to the satisfaction of Tanisys or the Exchange Agent that such tax has
been paid or is not payable.

     4.5. Tanisys may, without notice to any person, terminate all exchange
agencies after thirty (30) days following the Effective Date of the Merger, and
thereafter all exchanges, payments and notices provided for in these Articles of
Merger as being made to or by the Exchange Agent shall be made to or by Tanisys
or its transfer agent.

     4.6. The holder of a certificate or certificates representing shares of
Tech Common Stock issued and outstanding immediately prior to the Effective Date
of the Merger shall have no rights with respect to such shares other than to
exercise and perfect their right to dissent to the Merger and to receive the
fair value of such shares in the manner provided by Articles 5.11, 5.12 and 5.13
of the Texas Act or surrender such certificate or certificates pursuant to
Section 4.2 hereof.  The holder of a certificate or certificates representing
shares of the Tanisys Acquisition Common Stock issued and outstanding prior to
the Effective Date of the Merger shall have no rights with respect to such
shares other than to exercise and perfect their right to dissent to the Merger
and to receive the fair value of such shares in the manner provided by Article
262 of the Delaware Act.

     4.7. If the holder of any shares of Tech Common Stock issued and
outstanding immediately prior to the Effective Date of the Merger shall become
entitled to receive payment for such shares in accordance with the applicable
provisions of Articles 5.11, 5.12 and 5.13 of the Texas Act, then such payment
shall be in lieu of the conversion provided in Section 4.1 hereof and shall be
made by the Surviving Corporation.  Tech shall give Tanisys Acquisition and
Tanisys prompt notice upon receipt of any written objections to the Merger or
claims of appraisal rights and shall not without prior written consent of
Tanisys Acquisition and Tanisys make any payment with respect to, or settle or
offer to settle, any such objection or claim.  If the holder of any shares of
Tanisys Common Stock issued and outstanding immediately prior to the Effective
Date of the Merger shall become entitled to receive payment for such shares in
accordance with the applicable provisions of Article 262  of the Delaware Act,
then such payment shall be made by the Surviving Corporation.

       Rights and Duties of Tanisys Acquisition as the Surviving Corporation

     5.1. On the Effective Date of the Merger, the separate existence of Tech
shall cease for all purposes, and Tech shall be merged with and into Tanisys
Acquisition, which, as the Surviving Corporation, shall thereupon and thereafter
possess all of the rights, privileges, immunities, powers and franchises of a
public as well as of a private nature, and shall be subject to all the

any way impaired by reason of the Merger.

also be responsible and liable and subject to all restrictions, liabilities,
obligations, disabilities and duties of each Constituent Corporation; and any
claim existing or action or proceeding pending by or against any of the
Constituent Corporations may be prosecuted as if the Merger had not taken place
or the Surviving Corporation had been substituted in its place.  Neither the
rights of creditors nor any liens upon the property of any of the Constituent
Corporations shall be impaired by the Merger, and such rights and liens shall
attach to the Surviving Corporation, and may be enforced against it to the same
extent as if the Merger had not taken place.  If at any time the Surviving
Corporation shall consider or be advised that any further assignment or
assurances in law or any things are necessary or desirable to vest in the
Surviving Corporation, according to the terms hereof, the title of any property
or rights of Tech, the last acting officers and directors of Tech, as the case

the Surviving Corporation, and otherwise to carry out the purposes of the
Agreement and these Articles of Merger.

                                    THE MERGER

          Section 1.4  SURRENDER AND EXCHANGE OF DARKHORSE COMMON STOCK

     (a)  After the Effective Date, each holder of an outstanding certificate or
          certificates theretofore representing shares of DarkHorse Common Stock
          (the "DarkHorse Certificates") shall surrender such DarkHorse
          Certificates to Tanisys or to such agent or agents (the "Exchange
          Agent") as may be designated by Tanisys and shall receive in exchange
          therefor, upon satisfaction of customary delivery requirements and
          subject to applicable law with respect to the exercise of appraisal
          rights, certificates representing the number of whole shares of
          Tanisys Common Stock into 

                                    2
<PAGE>

          which shares of DarkHorse Common Stock have been converted, together 
          with a check representing the cash adjustments for fractional shares,
          if any.
     
     (b)  If any certificate evidencing shares of Tanisys Common Stock is to be
          issued in a name other than that in which the DarkHorse Certificate
          surrendered in exchange therefor is registered, it shall be a
          condition of the issuance thereof that the DarkHorse Certificate so
          surrendered shall be properly endorsed and otherwise be in proper form
          for transfer and that the person requesting such exchange pay to the
          Exchange Agent any transfer or other taxes required by reason of the
          issuance of a certificate for shares of Tanisys Common Stock in any
          name other than that of the registered holder of the DarkHorse
          Certificate surrendered or establish to the satisfaction of the
          Exchange Agent that such tax has been paid or is not payable.
     
     (c)  Until so surrendered and exchanged, each outstanding DarkHorse
          Certificate after the Effective Date shall be deemed for all corporate
          purposes (other than voting and the payment of dividends or other
          distributions as described below) to evidence the number of whole
          shares of Tanisys Common Stock into which the shares of DarkHorse
          Common Stock represented by such DarkHorse Certificates are to be
          converted pursuant to Section 1.2 of this Agreement; provided,
          however, that no dividends or other distributions, if any, in respect
          to such shares of Tanisys Common Stock, declared after the Effective
          Date and payable to holders of record after the Effective Date, shall
          be paid to the holders of any unsurrendered DarkHorse Certificates
          until such DarkHorse Certificates are surrendered.  Subject to the
          effect, if any, of applicable law, after the surrender and exchange of
          the DarkHorse Certificates, the record holders thereof on the date of
          exchange shall be entitled to receive any such dividends or other
          distributions without interest thereon, which theretofore have become
          payable with respect to the number of whole shares of Tanisys Common
          Stock for which such DarkHorse Certificate was exchangeable.  Holders
          of any unsurrendered DarkHorse Certificates shall not be entitled to
          vote until such unsurrendered DarkHorse Certificates are exchanged
          pursuant to this Section 1.4.  Holders of DarkHorse Common Stock who
          exercise appraisal rights in accordance with the provisions of the
          Texas Business Corporation Act (the "Texas Act") shall only be
          entitled to receive the fair value of their shares of DarkHorse Common
          Stock in accordance with Texas Act.  Such holders shall not be
          entitled to any dividends or other distributions  payable on and after
          the Effective Date to holders of Tanisys Common Stock with respect to
          the shares involved regardless of whether such holders have received
          payment for their shares.
     
     (d)  Tanisys may, without notice to any person, terminate all exchange
          agencies after thirty (30) days following the Effective Date of the
          Merger, and thereafter all exchanges, payments and notices provided
          for in this Agreement as being made to or by the Exchange Agent shall
          be made to or by Tanisys or its transfer agent.

                                    3

     Section 1.5  FRACTIONAL SHARES.  No fractional share certificates of 
Tanisys Common Stock shall be issued in connection with the conversion of shares
of DarkHorse Common Stock in the Merger, nor will any outstanding fractional
share interest entitle the Owners thereof to vote, to receive dividends or to
exercise any other right of a shareholder of Tanisys.  In lieu of any such
fractional shares, any holder of DarkHorse Common Stock shall, upon surrender
thereof, be paid in cash the value of each such fraction, which for this purpose
shall be the product of such fraction multiplied by the average of the per-share
closing prices of Tanisys Common Stock on the Vancouver Stock Exchange (the
"VSE") for the twenty (20) trading days immediately preceding the date that is
ten (10) days prior to the Effective Date, subject to appropriate adjustment in
the event of a stock split, stock dividend or recapitalization applicable to
shares of Tanisys Common Stock held of record on or before the Effective Date to
the extent not reflected in such sale prices.

     Section 1.6  NO FURTHER TRANSFERS.  On the Effective Date, the stock
transfer books of DarkHorse shall be closed, and no further transfer of
DarkHorse Common Stock shall thereafter be made.


                                      ARTICLE 2
                          REPRESENTATIONS AND WARRANTIES OF 
                              DARKHORSE AND THE OWNERS

     Except as expressly set forth in the Disclosure Schedule, which is attached
hereto as SCHEDULE "A," delivered to Tanisys by DarkHorse and the Owners,
severally, and contemporaneously with the execution hereof ("DarkHorse's
Disclosure Schedule"), DarkHorse hereby represents and warrants to Tanisys, and
the Owners, to their best knowledge and belief hereby represent and warrant to
Tanisys as follows, regardless of what investigations, if any, Tanisys shall
have made prior hereto (for the purpose of this Article 2, "Material" or
"Material Adverse Effect" shall mean an adverse effect in an amount in excess of
$10,000):

     Section 2.1  ORGANIZATION; QUALIFICATION.  DarkHorse is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Texas.  DarkHorse has full corporate power and authority to own and lease all of
the properties and assets it now owns and leases and to carry on its business as
now being conducted.  DarkHorse is duly qualified as a foreign corporation and
is in good standing to do business in each jurisdiction in which the property
owned, leased or operated by it or the nature of the business conducted by it
makes such qualification necessary, except where the failure so to qualify would
not have a Material Adverse Effect on the condition (financial or otherwise),
business, assets, liabilities, capitalization, financial position, operations,
results of operations or prospects  of DarkHorse. DarkHorse has heretofore
delivered to Tanisys complete and correct copies of its Articles of
Incorporation and By-Laws as such are currently in effect.

     Section 2.2  AUTHORITY RELATIVE TO THIS AGREEMENT.  DarkHorse has full
corporate power and authority to execute, deliver and perform this Agreement
and, subject to shareholder approval, to consummate the transactions
contemplated hereby.  The execution and delivery by DarkHorse of this Agreement,
and the consummation of the transactions contemplated hereby, have been duly 

                                   4
<PAGE>

and validly authorized by the Board of Directors of DarkHorse and, except for
approval of the Merger by the shareholders of DarkHorse, no other corporate
proceedings on the part of DarkHorse are necessary with respect thereto.  This
Agreement has been duly and validly executed and delivered by DarkHorse and,
subject to shareholder approval, constitutes a legal, valid and binding
obligation of DarkHorse, enforceable against it in accordance with its terms.

     Section 2.3  CAPITALIZATION.  The authorized capital stock of DarkHorse
consists of 100,000,000 shares of DarkHorse Common Stock, no par value, of
which, as of the date hereof, 1,455,000 shares of DarkHorse Common Stock are
validly issued and outstanding, fully paid and nonassessable.  As of the date of
this Agreement, there are no shares of DarkHorse Common Stock held in the
treasury of DarkHorse and there are no other shares of the capital stock of
DarkHorse.  As of the date hereof, except as disclosed in DarkHorse's Disclosure
Schedule, there are no outstanding options, warrants, rights or other
commitments to issue or sell any shares of capital stock or any securities or
obligations convertible into or exchangeable for, or giving any person any right
to acquire from DarkHorse, any shares of its capital stock.  No shares of
DarkHorse's capital stock have been issued in violation of any preemptive rights
or applicable federal or state securities laws.  Except pursuant to the Texas
Act, there are no restrictions, including but not limited to self-imposed
restrictions, on the retained earnings of DarkHorse or on the ability of
DarkHorse to declare and pay dividends.  There are no outstanding obligations of
DarkHorse to repurchase, redeem or otherwise acquire any capital stock or other
securities of DarkHorse.

     Section 2.4  NO SUBSIDIARIES; ABSENCE OF CERTAIN AGREEMENTS.  Except as
disclosed in DarkHorse's Disclosure Schedule, DarkHorse does not have any
Subsidiaries.  As used in this Agreement, "Subsidiary" or "Subsidiaries" with
respect to any corporation shall mean any other corporation of which at least a
majority of the securities having by their terms ordinary voting power to elect
a majority of the board of directors of such other corporation is at the time
directly or indirectly owned or controlled by such first corporation, or by such
first corporation and one or more of its Subsidiaries.  DarkHorse does not own
or hold any securities of, or any interest in, any other person or entity, nor
is DarkHorse subject to any joint venture, partnership or other arrangement that
is created as a partnership for federal income tax purposes.  Except as set
forth in DarkHorse's Disclosure Schedule, there are no voting trusts or other
agreements by and between or among DarkHorse, or any or all of its shareholders,
whether or not DarkHorse is a party thereto, imposing any restrictions upon the
transfer or voting of or otherwise pertaining to the securities of DarkHorse
(including but not limited to the DarkHorse Common Stock) or the ownership
thereof.  Any and all such restrictions set forth in DarkHorse's Disclosure
Schedule shall be duly complied with or effectively waived as of the Effective
Date.

     Section 2.5  GOVERNMENTAL CONSENTS AND APPROVALS.  Except as disclosed in
DarkHorse's Disclosure Schedule, the execution, delivery and performance by
DarkHorse of this Agreement and the consummation of the transactions
contemplated hereby by DarkHorse require no consent, approval, order or
authorization of, action by or in respect of, or registration or filing with,
any federal, state, municipal or other governmental department, commission,
board, bureau, agency, instrumentality, court, or authority ("Governmental
Body"), other than (a) the filing of the Articles of Merger with respect to the
Merger with the Secretary of State of the States of Texas and Delaware; (b) any
applicable filings with and consents and/or approvals of state security

                                   5
<PAGE>

commissions under state securities laws or similar laws; and (c) such other
consents, approvals, permits, authorizations, notifications or filings, the
failure of which to obtain or make would not have a Material Adverse Effect on
DarkHorse or materially adversely affect the ability of DarkHorse to perform its
obligations set forth herein or to consummate the transactions contemplated

rules or regulations promulgated thereunder, which relate to the use, ownership
or occupancy of the property or the operation of the business of DarkHorse.

     Section 2.13  PENSION MATTERS.  During the past five years, neither
DarkHorse nor any of its former Subsidiaries has maintained or contributed to
any defined benefit pension plans (as defined in Section 3(2) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) or any
multiemployer plans (as defined in Section 3(37)(A) of ERISA).  Each employee
benefit plan (as defined in Section 3(3) of ERISA) (each, an "Employee Benefit
Plan" or "Plan") maintained for employees of DarkHorse or any of its former
Subsidiaries to which DarkHorse or any of its former Subsidiaries have
contributed and any related trust agreement, annuity contract or any other
funding or implementing instrument complies currently and has complied in the
past, as to form, operation and administration, with the provisions of ERISA, as
amended, and all other applicable laws, rules and regulations and with the
Internal Revenue Code of 1986, as amended (the "Code"), where required in order
to be tax-qualified under Section 401(a) or 403(a) and 501(a) of the Code, and
no event has occurred that is reasonably likely to give rise to disqualification
of any such Plan under said Sections.  All necessary governmental approvals for
the Employee Benefit Plans have been obtained; each Employee Benefit Plan that
is subject thereto meets and has met at all times the minimum funding standards
of Section 302 of ERISA, Section 412 of the Code and any other applicable law,
and no accumulated funding deficiency, whether or not waived, exists with
respect to any such Plan; each Employee Benefit Plan that is an employee pension
benefit plan 

                                   8
<PAGE>

(as defined in Section 3(2)(A) of ERISA) has been duly authorized by the 
Board of Directors of DarkHorse and a favorable determination as to the 
qualification under the Code of each such employee pension benefit plan has 
been made by the Internal Revenue Service.

     Section 2.14  LABOR MATTERS.  Except as set forth in DarkHorse's Disclosure
Schedule, DarkHorse does not have any obligations, contingent or otherwise,

collective bargaining agreement is currently being negotiated by DarkHorse, and
DarkHorse has not experienced any material labor difficulty.  There has not
been, and there will not be, any adverse change in relations with employees of
DarkHorse as a result of any announcement or consummation of the transactions
contemplated by this Agreement.  No employee of DarkHorse is in violation of any
term of any employment contract, or any other contract or agreement with or any
restrictive covenant or any other common law obligation to a former employer
relating to the right of any such employee to be employed by DarkHorse because
of the nature of the business conducted or to be conducted by DarkHorse or to
the use of trade secrets or proprietary information of others, and the
employment of DarkHorse's employees does not subject DarkHorse to liability in
connection with such covenants or agreements.  There is neither pending nor
threatened Proceedings with respect to any contract, agreement, covenant or
obligation referred to above, nor is there any basis for asserting the
foregoing.

     Section 2.15  INFORMATION FOR FILINGS.  None of the information supplied or

          including investigative and settlement costs and attorneys' fees
          arising out of or in connection with any breach of representation or
          warranty of DarkHorse or Owners contained in Article 2 or Article 4
          hereof or in any certificate delivered pursuant hereto, regardless of
          whether Tanisys relied upon the truth of such representation or
          warranty or had any knowledge of any breach thereof.  On the Effective
          Date, fifteen percent (15%) of the Merger Consideration of Gary W.
          Pankonien, Archer Lawrence and Jack Little will be escrowed (the
          "Escrow") with U. S. Trust Company of Texas, N.A. (the "Escrow Agent")
          to secure and satisfy Tanisys' right to indemnification hereunder.  
     
     (b)  The Escrow shall be further defined in the Escrow Agreement attached
          hereto as EXHIBIT "C" and shall remain in effect for a period of six
          (6) months from the date of 

                                  23
<PAGE>

          closing of the Merger Agreement (such date, the "Escrow Termination 
          Date").  The Escrow may be maintained past the Escrow Termination Date
          only in the event of litigation concerning the Escrow.
     
     (c)  Upon receipt by Tanisys (the "Indemnified Party") of notice of any
          situation, event or occurrence that might give rise to a claim for
          indemnification of such Indemnified Party against DarkHorse and/or the
          Owners pursuant to this Section 5.13, the Indemnified Party shall give
          prompt written notice thereof to DarkHorse and the Owners (each such
          party, an "Indemnifying Party"), indicating the nature of such
          indemnification.  Failure to give any notice provided under this
          Section 5.13(b) shall in no way be deemed a forfeiture of the
          Indemnified Party's rights to be indemnified under Section 5.13
          provided that such notice is given prior to the Escrow Termination
          Date.  A claim for indemnity may, at the option of the Indemnified
          Party, be asserted as soon as any situation, event or occurrence has
          been noticed by the Indemnified Party, regardless of whether actual
          harm has been suffered or out-of-pocket expenses incurred.
     
     (d)  DarkHorse's and the Owners' indemnification will be limited to
          situations, events and/or occurrences of which Tanisys provides notice
          to the Owners prior to the Escrow Termination Date and to the amount
          of, and only from shares comprising, the Escrow.   Tanisys will not be
          eligible to obtain any indemnification from the Escrow until the
          aggregate amount of all losses, expenses, damages, deficiencies,
          liabilities and other obligations arising out of or in connection with
          any breach of representation or warranty of DarkHorse or the Owners
          exceeds $10,000 in the aggregate and then only for the amount of such
          excess.  Shares released from the Escrow after such time will be
          returned to the Owners in accordance with the terms of the Escrow
          Agreement.  
     
     Section 5.14  INDEMNIFICATION BY TANISYS.

     (a)  Tanisys shall indemnify and hold Owner harmless from and against, and
          promptly reimburse Owner for, any and all loss, expense, damage,
          deficiency, liability or obligation, including investigative and
          settlement costs and attorneys' fees, arising out of or in connection
          with any breach of representation or warranty of Tanisys contained in
          Article 3 hereof, or in any certificate delivered pursuant hereto,
          regardless of whether Owner relied upon the truth of such
          representation or warranty or had any knowledge of any breach thereof.
     
     (b)  Upon receipt by Owner (the "Indemnified Party") of notice of any
          situation, event or occurrence that might give rise to a claim for
          indemnification of such Indemnified Party against Tanisys pursuant to
          this Section, the Indemnified Party shall give prompt written notice
          thereof to Tanisys indicating the nature of such indemnification.  A
          claim for indemnity may, at the option of the Indemnified Party, be
          asserted as soon as any situation, event or occurrence has been
          noticed by the 

                                  24
<PAGE>

          Indemnified Party regardless of whether actual harm has been suffered
          or out-of-pocket expenses incurred.

     Section 5.15  RESALE LIMITATIONS.  DarkHorse and the Owners agree to
certain resale restrictions and further agree to advise its Affiliates and
future Owners of the resale restrictions imposed by the VSE and federal
securities laws on shares of Tanisys Common Stock received by them pursuant to
the Merger, and will cause each Affiliate to sign the Restricted Stock
Investment Letter stating that such Affiliate and future Owners are aware of
such restrictions and as set forth in Section 6.3(h) herein.

     Section 8.1  EXCLUSIVE REMEDY.  Any controversy or claim between or among
the parties hereto including but not limited to those arising out of Sections
5.13 and 5.14 of this Agreement or any related instruments, including any claim
based on or arising from an alleged tort, shall be determined by binding
arbitration in accordance with the rules of practice and procedure for the
arbitration of commercial disputes of Chapter 171 of the Texas Civil Practice
and Remedies Code (the "Texas Arbitration Act") and the rules set forth herein. 
Such remedy shall be the exclusive remedy for any such controversy or claim. 
Judgment upon any arbitration award may be entered in any court having
jurisdiction.  Any party to this Agreement may bring an action, including a
summary or expedited proceeding to compel arbitration of any controversy or
claim to which this Agreement applies in any court having jurisdiction over such
action.  The arbitration shall be conducted in the City of Austin, Texas, and
administered in accordance with the Texas Arbitration Act.  The parties shall
attempt to agree on one person to serve as the arbitrator for any controversy or
claim hereunder.  In the event the parties are unable to agree on a single
arbitrator, each of the parties to this Agreement shall appoint one person as a
arbitrator to hear and determine the dispute and the two arbitrators so chosen
shall select a third impartial arbitrator whose decision shall be final and
conclusive as to all matters subject to arbitration hereunder.  If for any
reason a third arbitrator cannot be named under the previous provisions, any
state district judge sitting in Travis County, Texas, upon application by one of
the parties hereto, shall have the power to appoint one or more arbitrators to
resolve disputes hereunder.  All arbitration hearings will be commenced within

                 AMENDMENT NO. 1 TO AGREEMENT AND PLAN OF MERGER


     This Amendment No. 1 amends that certain Agreement and Plan of Merger 
dated April 9, 1996 (the "Agreement"), by and among Tanisys Technology, Inc. 
("Tanisys"), Tanisys Acquisition Corp. II ("Tanisys Acquisition"), DarkHorse 
Systems, Inc. ("DarkHorse"), Gary W. Pankonien, Archer Lawrence and Jack 
Little (collectively, the "Owners") as follows:

     1.   Section 1.2, CONVERSION OF SHARES, is hereby amended in its entirety
to read as follows:

          "Section 1.2  CONVERSION OF SHARES.  Upon the latter of the
     issuance of a Certificate of Merger by the Secretary of State of the
     State of Delaware or the issuance of a Certificate of Merger by the
     Secretary of State of the State of Texas (the "Effective Date"), the
     issued and outstanding shares of common stock, no par value per share,
     of DarkHorse (the "DarkHorse Common Stock"), subject to the
     fulfillment of the conditions precedent set forth under Article 6,
     including the simultaneous closing of that certain Agreement and Plan
     of Merger dated April 9, 1996, by and between Tanisys Technology,
     Inc., Tanisys Acquisition Corp. and 1st Tech Corporation and Gary W.
     Pankonien and the applicable statutory provisions with respect to
     appraisal rights, any applicable withholding requirements and
     adjustment as herein provided, shall be converted into and become, and
     there shall be paid and issued, in exchange for the DarkHorse Common
     Stock an aggregate of 1,200,000 shares of Tanisys common stock, no par
     value per share (the "Tanisys Common Stock"), such that each share of
     DarkHorse Common Stock outstanding on the Effective Date, not to
     exceed 1,200,000 shares of DarkHorse Common Stock in the aggregate, is
     exchanged for one (1) share (the "Exchange Ratio") of Tanisys Common
     Stock, with any excess shares of DarkHorse Common Stock resulting in a
     reduction in the per-share Exchange Ratio.  As used in this Agreement,
     "Merger Consideration" shall mean the aggregate of 1,200,000 shares of
     Tanisys Common Stock exchanged for DarkHorse Common Stock in the
     Merger at the Exchange Ratio.  Each share of DarkHorse Common Stock
     held in the treasury of DarkHorse or by a wholly owned subsidiary of
     DarkHorse shall be cancelled as of the Effective Date and no portion
     of the Merger Consideration shall be payable with respect thereto. 
     The Merger Consideration shall be reduced by the amount otherwise
     payable or issuable to holders of DarkHorse who exercise dissenters'
     rights, if any, in connection with the Merger based upon such
     shareholders' ownership of DarkHorse Common Stock outstanding on the
     Effective Date.  The Exchange Ratio shall be subject to appropriate
     adjustment in the event of a stock split, stock dividend or
     recapitalization subsequent to the date of this Agreement applicable
     to shares of DarkHorse Common Stock or Tanisys Common Stock held of
     record on or before the Effective Date."

<PAGE>

     2.   Section 2.3, CAPITALIZATION, is hereby amended in its entirety to read
     as follows:

          "Section 2.3  CAPITALIZATION.  The authorized capital stock of
     DarkHorse consists of 100,000,000 shares of DarkHorse Common Stock, no
     par value, of which, as of the date hereof, 1,155,000 shares of
     DarkHorse Common Stock are validly issued and outstanding, fully paid
     and nonassessable, and upon the Effective Date, there will be no more
     than 1,200,000 shares of DarkHorse Common Stock validly issued and
     outstanding, fully paid and nonassessable.  As of the date of this
     Agreement, there are no shares of DarkHorse Common Stock held in the
     treasury of DarkHorse and there are no other shares of the capital
     stock of DarkHorse.  As of the date hereof, except as disclosed in
     DarkHorse's Disclosure Schedule, there are no outstanding options,
     warrants, rights or other commitments to issue or sell any shares of
     capital stock or any securities or obligations convertible into or
     exchangeable for, or giving any person any right to acquire from
     DarkHorse, any shares of its capital stock.  No shares of DarkHorse's
     capital stock have been issued in violation of any preemptive rights
     or applicable federal or state securities laws.  Except pursuant to
     the Texas Act, there are no restrictions, including but not limited to
     self-imposed restrictions, on the retained earnings of DarkHorse or on
     the ability of DarkHorse to declare and pay dividends.  There are no
     outstanding obligations of DarkHorse to repurchase, redeem or
     otherwise acquire any capital stock or other securities of DarkHorse."

     3.   Section 4.1, TITLE TO SHARES, is hereby amended in its entirety to
read as follows:
               "Section 4.1  TITLE TO SHARES.  Immediately prior to the
     Closing, the Owners shall be the lawful Owners and holders of an
     aggregate of no more than 1,200,000 shares of DarkHorse Common Stock
     and, on the Effective Date, shall hold all such shares free and clear
     of any encumbrances or liens."

     5.   All references to "1,500,000" shares of DarkHorse Common Stock or
Tanisys Common Stock in documents relating to the Agreement, including but not
limited to the exhibits and schedules attached to the Agreement, are hereby
changed to "1,200,000."

     6.   Section 5.16, REGISTRATION STATEMENT, is hereby added to the
Agreement, as follows:

               "Section 5.16  REGISTRATION STATEMENT.  In the event Tanisys
     elects to file a Registration Statement on Form S-1 or S-3 with the
     Securities and Exchange Commission ("SEC") and is requested to do so
     by the Owners, Tanisys agrees to register for sale up to 20,000 shares
     of the Merger Consideration for the Owners and to cause such
     Registration Statement to become effective as promptly as practical
     thereafter and to maintain the effectiveness of such Registration
     Statement until the earlier of the sale of the shares registered
     thereby or the second anniversary of the Effective Date.  Tanisys
     shall be permitted to include on any such Registration Statement
     shares of the Tanisys Common Stock to be issued (i) by the company or
     by stockholders with registration rights directly to the public and/or
     to institutional

                                      -2-

<PAGE>

     investors for cash, or (ii) by stockholders receiving registration rights
     in connection with any acquisitions to be completed by Tanisys prior to,
     simultaneously with, or subsequent to, completion of the Merger.  Tanisys
     shall also take any action required to be taken under any applicable state
     blue sky or securities laws in connection with the issuance of the shares 
     of the Tanisys Common Stock to be issued as set forth in this Agreement or
     the listing of such shares of the Tanisys Common Stock on the NASDAQ 
     National Market System, subject to official notice of issuance.  The Owners
     shall furnish to Tanisys, in writing, all information and covenants 
     concerning DarkHorse, the other holders of the DarkHorse Common Stock and 
     the proposed methods of sale or other disposition of the registered shares 
     as Tanisys, any underwriter, the SEC and/or any state or other regulatory 
     authority may request in connection with the registration of any shares or 
     any action required by Tanisys.  The Owners will cooperate with Tanisys and
     use reasonable efforts to assist Tanisys in, and Tanisys will bear all 
     costs and expenses (including its legal, accounting and printing costs and 
     filing fees payable to the SEC and other governmental bodies) related to, 
     the preparation and filing of the Registration Statement and all other
     necessary documentation and to obtain all permits, consents, approvals
     and authorizations of all third parties and governmental bodies necessary 
     to effect the registration of the 20,000 shares of the Merger Consideration
     on the Registration Statement.  The Owners agree to execute, deliver and/or
     file with or supply to Tanisys, any underwriter, the SEC and/or any state 
     or other regulatory authority such information as is necessary to carry out
     the provisions of this Section or to effect the registration or 
     qualification of the shares under applicable securities laws and 
     regulations of any jurisdiction and such information as Tanisys may 
     reasonably require to ensure that the transfer or disposition of the 
     registered shares is not in violation of any applicable securities laws.  
     The parties shall also enter into an agreement to provide reciprocal 
     indemnities to the other party for representations made in such 
     Registration Statement and related documents.  Each of the Owners further 
     agrees to furnish to Tanisys not later than every thirty (30) days after 
     the date of effectiveness of the Registration Statement a report of the 
     number of registered shares sold during such thirty (30)-day period and to
     cancel any orders to sell and/or to reverse any sales of registered
     shares which orders and/or sales, in Tanisys' opinion, based upon the
     opinion of legal counsel experienced in securities law matters were
     effected in violation of applicable federal or state securities laws. 
     At its expense, Tanisys will furnish to each of the Owners such number
     of copies of such Registration Statement and of each amendment and
     supplement thereto (in each case, including all Exhibits) and such
     number of copies of the prospectus included in such Registration
     Statement as they shall request.  Tanisys will notify the Owners of
     any shares covered by such Registration Statement (i) at any time when
     a prospectus relating thereto is required to be delivered under
     applicable securities laws, (ii) of the happening of any event as a
     result of which the prospectus included in such Registration Statement
     as then in effect includes an untrue statement of material fact or
     omits to state any material fact required to be stated therein or
     necessary to make the statements therein not misleading in the light
     of the circumstances then existing, or (iii) of any other occurrence
     which, under applicable


                                      -3-

<PAGE>

     securities laws, requires the prospectus to be revised or updated (and 
     upon receipt of such notice and until a supplemented or amended prospectus
     is available, each of the Owners will cease to offer or to sell any shares
     covered by the Registration Statement and will return all copies of the 
     prospectus to Tanisys if requested to do so by Tanisys and will not sell 
     any of the shares until provided with a current prospectus and notice 
     from Tanisys that they may resume their selling efforts).  Upon the 
     occurrence of any of the events described in clauses (ii) or (iii) of the 
     preceding sentence, Tanisys agrees to use its best efforts to take all 
     necessary actions to revise or update the prospectus as promptly as 
     practical to the extent necessary for selling efforts to resume."

     7.   All undefined capitalized terms used in this Amendment shall have the
meanings set forth in the Agreement.

     8.   All terms and conditions of the Agreement and related documents not
specifically modified herein are hereby ratified and confirmed in their
entirety.


     IN WITNESS WHEREOF, this Amendment No. 1 to the Agreement has been duly
executed by each of the parties to the Agreement as of the 16th day of May,
1996.

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

     Pursuant to the provisions of Article 262 of the Delaware Corporation Act

the provisions of Article 251 of the Delaware Act.  Tanisys Acquisition II and
DarkHorse are sometimes referred to herein as the "Constituent Corporations."

                                   RECITALS

     Tanisys Acquisition II is a corporation duly organized and existing under

<PAGE>

     The respective Boards of Directors of Tanisys Acquisition II and DarkHorse
deem it advisable and in the best interests of each such corporation and their

Acquisition II as provided herein and in the Agreement, and they have
accordingly adopted resolutions approving the Agreement and these Articles of
Merger, and the Agreement and these Articles of Merger have been approved by the

     Therefore, in consideration of the premises and the mutual covenants and
agreements herein contained, the parties hereto covenant and agree to the

                                   ARTICLE 4.

                    Manner and Basis of Converting Shares

     4.1. On the Effective Date of the Merger, subject to Section 4.7 hereof,
each share of Tanisys Acquisition II Common Stock issued and outstanding
immediately prior to the Effective Date of the Merger (other than Tanisys
Acquisition II Appraisal Shares (as hereinafter defined), all of which shall be
cancelled) shall continue to remain outstanding and unchanged.  "Tanisys
Acquisition II Appraisal Shares" are those shares of Tanisys Acquisition II
Common Stock as to which shareholders of Tanisys Acquisition II have properly
exercised and perfected their right to dissent and receive the fair value
thereof in accordance with Article 262 of the Delaware Act.  Also on the
Effective Date of the Merger, subject to Sections 4.3 and 4.7 hereof and
adjustment as provided herein, each share of DarkHorse Common Stock issued and
outstanding immediately prior to the Effective Date of the Merger (other than
DarkHorse Appraisal Shares (as hereinafter defined), all of which shares shall
be cancelled), not to exceed 1,200,000 shares of DarkHorse Common Stock in the
aggregate, shall, by virtue of the Merger and without any action on the part of
the holder thereof, thereupon be converted into and become, in exchange for each
share of DarkHorse Common Stock, one (1) share (the "Exchange Ratio") of Tanisys
common stock, no par value per share (the "Tanisys Common Stock"), with any
excess shares of DarkHorse Common Stock resulting in a reduction in the per-
share Exchange Ratio.  In the event that DarkHorse has less than 1,200,000
shares of DarkHorse Common Stock outstanding on the Effective Date of the
Merger, the Exchange Ratio shall be proportionally increased.  Each share of
DarkHorse Common Stock held in the treasury of DarkHorse or by a wholly-owned
subsidiary 


                                       3
<PAGE>

of DarkHorse shall be cancelled as of the Effective Date of the Merger, and 
no portion of the Merger Consideration (as hereinafter defined) shall be 
payable with respect thereto.  As used in these Articles of Merger, "Merger 
Consideration" shall mean the aggregate of 1,200,000 shares of Tanisys Common 
Stock exchanged for DarkHorse Common Stock in the Merger at the Exchange 
Ratio.  The Merger Consideration shall be reduced by the amount otherwise 
payable or issuable to holders of DarkHorse who exercise dissenters' rights 
in connection with the Merger based upon such shareholders' ownership of 
DarkHorse Common Stock outstanding on the Effective Date of the Merger.  The 
Exchange Ratio shall be subject to appropriate adjustment in the event of a 
stock split, stock dividend or recapitalization subsequent to the date of the 
Agreement applicable to shares of DarkHorse Common Stock or Tanisys Common 
Stock held of record on or before the Effective Date of the Merger.  
"DarkHorse Appraisal Shares" are those shares of DarkHorse Common Stock as to 
which shareholders have properly exercised and perfected their right to 
dissent and to receive the fair value thereof in accordance with Articles 
5.11, 5.12 and 5.13 of the Texas Act.

     4.2. After the Effective Date of the Merger, each holder of record of an
outstanding certificate or certificates representing shares of DarkHorse Common
Stock shall surrender such certificate or certificates to Tanisys or to such
agent or agents as shall be appointed by Tanisys (the "Exchange Agent") and
shall be entitled to receive in exchange therefor (except to the extent such
certificate or certificates represent DarkHorse Appraisal Shares) a certificate
or certificates representing the number of whole shares of Tanisys Common Stock
into which the shares of DarkHorse Common Stock theretofore represented by the
certificate or certificates so surrendered shall have been converted, together
with a check representing the cash adjustments for fractional shares, if any. 
Except as otherwise provided herein, each share of DarkHorse Common Stock issued
and outstanding immediately prior to the Effective Date of the Merger shall on
and after the Effective Date of the Merger be deemed for all corporate purposes
to evidence ownership of the number of shares of Tanisys Common Stock into which
such shares have been converted.  Until certificates representing shares of
DarkHorse Common Stock shall be surrendered and exchanged for certificates
representing shares of Tanisys Common Stock, no dividend or other distributions,
if any, payable to holders of record of Tanisys Common Stock as of any date
subsequent to the Effective Date of the Merger shall be paid to the holders of
such outstanding certificates of DarkHorse Common Stock.  Holders of
unsurrendered certificates for shares of DarkHorse Common Stock shall not be
entitled to vote until such unsurrendered certificates for shares of DarkHorse
Common Stock are exchanged pursuant to this Section 4.2.  Upon surrender and
exchange of such outstanding certificates of DarkHorse Common Stock and subject
to the effect, if any, of applicable law, there shall be paid to the record
holders of the certificates issued in exchange therefor, the amount, without
interest thereon, of dividends and other distributions, if any, which has become
payable after the Effective Date of the Merger with respect to the number of
whole shares of Tanisys Common Stock represented thereby.  Immediately prior to
the Effective Date of the Merger, all outstanding stock options or rights to
purchase DarkHorse Common Stock, if any, shall be surrendered by the respective
holders thereof and shall terminate and be cancelled and shall have no further
force and effect whatsoever.


                                       4
<PAGE>

     4.3. Tanisys shall not be required to issue, and no certificates shall be
issued, for a fraction of a share of Tanisys Common Stock to any shareholder of
Tanisys in respect of fractional interests, but in lieu thereof each such holder
of shares of Tanisys Common Stock who would otherwise have been entitled to a
fraction of a share of Tanisys Common Stock, upon compliance with Section 4.2
hereof, shall be paid cash equal to such fraction multiplied by the average of
the per-share closing prices of Tanisys Common Stock on the Vancouver Stock
Exchange for the twenty (20) trading days immediately preceding the date that is
ten (10) days prior to the Effective Date of the Merger, subject to appropriate
adjustment in the event of a stock split, stock dividend or recapitalization
applicable to shares of Tanisys Common Stock held of record on or before the
Effective Date of the Merger to the extent not reflected in such sales prices.

     4.4. If any certificate evidencing shares of Tanisys Common Stock is to be
issued in a name other than that in which the DarkHorse certificate surrendered
in exchange therefor is registered, it shall be a condition of the issuance
thereof that the certificate so surrendered shall be properly endorsed and
otherwise in proper form for transfer and that the person requesting such
exchange pay to Tanisys or the Exchange Agent any transfer or other taxes
required by reason of the issuance of a certificate for shares of Tanisys Common
Stock in any name other than that of the registered holder of the certificate
surrendered or establish to the satisfaction of Tanisys or the Exchange Agent
that such tax has been paid or is not payable.

     4.5. Tanisys may, without notice to any person, terminate all exchange
agencies after thirty (30) days following the Effective Date of the Merger, and
thereafter all exchanges, payments and notices provided for in these Articles of
Merger as being made to or by the Exchange Agent shall be made to or by Tanisys
or its transfer agent.

     4.6. The holder of a certificate or certificates representing shares of
DarkHorse Common Stock issued and outstanding immediately prior to the Effective
Date of the Merger shall have no rights with respect to such shares other than
to exercise and perfect their right to dissent to the Merger and to receive the
fair value of such shares in the manner provided by Articles 5.11, 5.12 and 5.13
of the Texas Act or surrender such certificate or certificates pursuant to
Section 4.2 hereof.  The holder of a certificate or certificates representing
shares of the Tanisys Acquisition II Common Stock issued and outstanding prior
to the Effective Date of the Merger shall have no rights with respect to such
shares other than to exercise and perfect their right to dissent to the Merger
and to receive the fair value of such shares in the manner provided by Article
262 of the Delaware Act.

     4.7. If the holder of any shares of DarkHorse Common Stock issued and
outstanding immediately prior to the Effective Date of the Merger shall become
entitled to receive payment for such shares in accordance with the applicable
provisions of Articles 5.11, 5.12 and 5.13 of the Texas Act, then such payment
shall be in lieu of the conversion provided in Section 4.1 hereof and shall be
made by the Surviving Corporation.  DarkHorse shall give Tanisys Acquisition II


                                       5
<PAGE>

and Tanisys prompt notice upon receipt of any written objections to the Merger
or claims of appraisal rights and shall not without prior written consent of
Tanisys Acquisition II and Tanisys make any payment with respect to, or settle
or offer to settle, any such objection or claim.  If the holder of any shares of
Tanisys Common Stock issued and outstanding immediately prior to the Effective
Date of the Merger shall become entitled to receive payment for such shares in
accordance with the applicable provisions of Article 262 of the Delaware Act,
then such payment shall be made by the Surviving Corporation.


                                   ARTICLE 5.

   Rights and Duties of Tanisys Acquisition II as the Surviving Corporation

Corporations shall be impaired by the Merger, and such rights and liens shall
attach to the Surviving Corporation, and may be enforced against it to the same
extent as if the Merger had not taken place.  If at any time the Surviving
Corporation shall consider or be advised that any further assignment or
assurances in law or any things are necessary or desirable to vest in the
Surviving Corporation, according to the terms hereof, the title of any property
or rights of DarkHorse, the last acting officers and directors of DarkHorse, as

Incorporation of the Surviving Corporation and such Bylaws.


                                   ARTICLE 3.

elected and qualified or until his resignation, death or removal, in

     Keith D. Thatcher                  Vice President, Chief Financial Officer
                                          and Corporate Treasurer

                                   ARTICLE 4.

                     Manner and Basis of Converting Shares

     4.1. On the Effective Date of the Merger, subject to Section 4.7 hereof,
each share of Tanisys Acquisition II Common Stock issued and outstanding
immediately prior to the Effective Date of the Merger (other than Tanisys
Acquisition II Appraisal Shares (as hereinafter defined), all of which shall be
cancelled) shall continue to remain outstanding and unchanged.  "Tanisys
Acquisition II Appraisal Shares" are those shares of Tanisys Acquisition II
Common Stock as to which shareholders of Tanisys Acquisition II have properly
exercised and perfected their right to dissent and receive the fair value
thereof in accordance with Article 262 of the Delaware Act.  Also on the
Effective Date of the Merger, subject to Sections 4.3 and 4.7 hereof and
adjustment as provided herein, each share of DarkHorse Common Stock issued and
outstanding immediately prior to the Effective Date of the Merger (other than
DarkHorse Appraisal Shares (as hereinafter defined), all of which shares shall
be cancelled), not to exceed 1,200,000 shares of DarkHorse Common Stock in the
aggregate, shall, by virtue of the Merger and without any action on the part of
the holder thereof, thereupon be converted into and become, in exchange for each
share of DarkHorse Common Stock, one (1) share (the "Exchange Ratio") of Tanisys
common stock, no par value per share (the "Tanisys Common Stock"), with any
excess shares of DarkHorse Common Stock resulting in a reduction in the per-
share Exchange Ratio.  In the event that DarkHorse has less than 1,200,000
shares of DarkHorse Common Stock outstanding on the Effective Date of the
Merger, the Exchange Ratio shall be proportionally increased.  Each share of
DarkHorse Common Stock held in the treasury of DarkHorse or by a wholly-owned
subsidiary of DarkHorse shall be cancelled as of the Effective Date of the
Merger, and no portion of the Merger Consideration (as hereinafter defined)
shall be payable with respect thereto.  As used in these Articles of Merger,
"Merger Consideration" shall mean the aggregate of 1,200,000 shares of Tanisys
Common Stock exchanged for DarkHorse Common Stock in the Merger at the Exchange
Ratio.  The Merger Consideration shall be reduced by the amount otherwise
payable or issuable to holders of DarkHorse who exercise dissenters' rights in
connection with the Merger based upon such shareholders' ownership of DarkHorse
Common Stock outstanding on the Effective Date of the Merger.  The Exchange
Ratio shall be subject to appropriate adjustment in 


                                       3
<PAGE>

the event of a stock split, stock dividend or recapitalization subsequent to 
the date of the Agreement applicable to shares of DarkHorse Common Stock or 
Tanisys Common Stock held of record on or before the Effective Date of the 
Merger.  "DarkHorse Appraisal Shares" are those shares of DarkHorse Common 
Stock as to which shareholders have properly exercised and perfected their 
right to dissent and to receive the fair value thereof in accordance with 
Articles 5.11, 5.12 and 5.13 of the Texas Act.

     4.2. After the Effective Date of the Merger, each holder of record of an
outstanding certificate or certificates representing shares of DarkHorse Common
Stock shall surrender such certificate or certificates to Tanisys or to such
agent or agents as shall be appointed by Tanisys (the "Exchange Agent") and
shall be entitled to receive in exchange therefor (except to the extent such
certificate or certificates represent DarkHorse Appraisal Shares) a certificate
or certificates representing the number of whole shares of Tanisys Common Stock
into which the shares of DarkHorse Common Stock theretofore represented by the
certificate or certificates so surrendered shall have been converted, together
with a check representing the cash adjustments for fractional shares, if any. 
Except as otherwise provided herein, each share of DarkHorse Common Stock issued
and outstanding immediately prior to the Effective Date of the Merger shall on
and after the Effective Date of the Merger be deemed for all corporate purposes
to evidence ownership of the number of shares of Tanisys Common Stock into which
such shares have been converted.  Until certificates representing shares of
DarkHorse Common Stock shall be surrendered and exchanged for certificates
representing shares of Tanisys Common Stock, no dividend or other distributions,
if any, payable to holders of record of Tanisys Common Stock as of any date
subsequent to the Effective Date of the Merger shall be paid to the holders of
such outstanding certificates of DarkHorse Common Stock.  Holders of
unsurrendered certificates for shares of DarkHorse Common Stock shall not be
entitled to vote until such unsurrendered certificates for shares of DarkHorse
Common Stock are exchanged pursuant to this Section 4.2.  Upon surrender and
exchange of such outstanding certificates of DarkHorse Common Stock and subject
to the effect, if any, of applicable law, there shall be paid to the record
holders of the certificates issued in exchange therefor, the amount, without
interest thereon, of dividends and other distributions, if any, which has become
payable after the Effective Date of the Merger with respect to the number of
whole shares of Tanisys Common Stock represented thereby.  Immediately prior to
the Effective Date of the Merger, all outstanding stock options or rights to
purchase DarkHorse Common Stock, if any, shall be surrendered by the respective
holders thereof and shall terminate and be cancelled and shall have no further
force and effect whatsoever.

     4.3. Tanisys shall not be required to issue, and no certificates shall be
issued, for a fraction of a share of Tanisys Common Stock to any shareholder of
Tanisys in respect of fractional interests, but in lieu thereof each such holder
of shares of Tanisys Common Stock who would otherwise have been entitled to a
fraction of a share of Tanisys Common Stock, upon compliance with Section 4.2
hereof, shall be paid cash equal to such fraction multiplied by the average of
the per-share closing prices of Tanisys Common Stock on the Vancouver Stock
Exchange for the twenty (20) trading days immediately preceding the date that is
ten (10) days prior to the Effective Date of the Merger, subject to appropriate
adjustment in the event of a stock split, stock dividend or recapitalization
applicable to shares of Tanisys Common Stock held 


                                       4
<PAGE>

of record on or before the Effective Date of the Merger to the extent not 
reflected in such sales prices.

     4.4. If any certificate evidencing shares of Tanisys Common Stock is to be
issued in a name other than that in which the DarkHorse certificate surrendered
in exchange therefor is registered, it shall be a condition of the issuance
thereof that the certificate so surrendered shall be properly endorsed and
otherwise in proper form for transfer and that the person requesting such
exchange pay to Tanisys or the Exchange Agent any transfer or other taxes
required by reason of the issuance of a certificate for shares of Tanisys Common
Stock in any name other than that of the registered holder of the certificate
surrendered or establish to the satisfaction of Tanisys or the Exchange Agent
that such tax has been paid or is not payable.

     4.5. Tanisys may, without notice to any person, terminate all exchange
agencies after thirty (30) days following the Effective Date of the Merger, and
thereafter all exchanges, payments and notices provided for in these Articles of
Merger as being made to or by the Exchange Agent shall be made to or by Tanisys
or its transfer agent.

     4.6. The holder of a certificate or certificates representing shares of
DarkHorse Common Stock issued and outstanding immediately prior to the Effective
Date of the Merger shall have no rights with respect to such shares other than
to exercise and perfect their right to dissent to the Merger and to receive the
fair value of such shares in the manner provided by Articles 5.11, 5.12 and 5.13
of the Texas Act or surrender such certificate or certificates pursuant to
Section 4.2 hereof.  The holder of a certificate or certificates representing
shares of the Tanisys Acquisition II Common Stock issued and outstanding prior
to the Effective Date of the Merger shall have no rights with respect to such
shares other than to exercise and perfect their right to dissent to the Merger
and to receive the fair value of such shares in the manner provided by Article
262 of the Delaware Act.

     4.7. If the holder of any shares of DarkHorse Common Stock issued and
outstanding immediately prior to the Effective Date of the Merger shall become
entitled to receive payment for such shares in accordance with the applicable
provisions of Articles 5.11, 5.12 and 5.13 of the Texas Act, then such payment
shall be in lieu of the conversion provided in Section 4.1 hereof and shall be
made by the Surviving Corporation.  DarkHorse shall give Tanisys Acquisition II
and Tanisys prompt notice upon receipt of any written objections to the Merger
or claims of appraisal rights and shall not without prior written consent of
Tanisys Acquisition II and Tanisys make any payment with respect to, or settle
or offer to settle, any such objection or claim.  If the holder of any shares of
Tanisys Common Stock issued and outstanding immediately prior to the Effective
Date of the Merger shall become entitled to receive payment for such shares in
accordance with the applicable provisions of Article 262 of the Delaware Act,
then such payment shall be made by the Surviving Corporation.

     Rights and Duties of Tanisys Acquisition II as the Surviving Corporation

     5.1. On the Effective Date of the Merger, the separate existence of
DarkHorse shall cease for all purposes, and DarkHorse shall be merged with and

Corporation without further act or deed.  The title to any real estate vested by
deed or otherwise, in either of the Constituent Corporations, shall not revert
or be in any way impaired by reason of the Merger.

     5.2. On the Effective Date of the Merger, the Surviving Corporation shall
also be responsible and liable and subject to all restrictions, liabilities,
obligations, disabilities and duties of each Constituent Corporation; and any

Constituent Corporations may be prosecuted as if the Merger had not taken place
or the Surviving Corporation had been substituted in its place.  Neither the
rights of creditors nor any liens upon the property of any of the Constituent
Corporations shall be impaired by the Merger, and such rights and liens shall
attach to the Surviving Corporation, and may be enforced against it to the same
extent as if the Merger had not taken place.  If at any time the Surviving
Corporation shall consider or be advised that any further assignment or
assurances in law or any things are necessary or desirable to vest in the
Surviving Corporation, according to the terms hereof, the title of any property
or rights of DarkHorse, the last acting officers and directors of DarkHorse, as
the case may be, or the corresponding officers and directors of the Surviving
Corporation shall and will execute and make all such proper assignments and
assurances and do all things necessary or proper to vest title in such property
or rights in the Surviving Corporation, and otherwise to carry out the purposes
of the Agreement and these Articles of Merger.

                              EMPLOYMENT AGREEMENT


   THIS EMPLOYMENT AGREEMENT is made effective the 15th day of February, 1994,
by and between ROSETTA TECHNOLOGIES INC., a Wyoming corporation, with principal
offices located at 1310 Ranch Road 620 South, Suite B195, Austin, Texas 
78734-6342 (hereinafter referred to as the "Employer"), and MARK C. HOLLIDAY, a
resident of Austin, Texas (hereinafter referred to as the "Employee").

                              W I T N E S S E T H:

   WHEREAS, the Employer desires to employ the Employee, and the Employee and
Employer desire to enter into an agreement relating to such employment,
outlining the duties and obligations of each:

   NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein set forth, it is agreed as follows:

   1.   EMPLOYMENT.  The Employer agrees to employ the Employee, and the
Employee agrees to be employed by the Employer, subject to the terms and
conditions set forth herein.

   2.   TERM.  Subject to the provisions hereof, the term of the Employee's
employment by the Employer under this Agreement shall expire on February 14, 
1995; provided that such term of employment shall continue thereafter unless 
and until terminated by either the Employer or the Employee upon no less than 
one hundred twenty (120) days' prior written notice to the other of the 
desire to terminate such employment.  The term of the Employee's employment 
hereunder, including any continuation of the original term, is hereinafter 
referred to as the "Employment Period."

   3.   POSITION AND DUTIES.  During the Employment Period, the Employee shall
serve as President and Chief Executive Officer of the Employer with such
assignments, powers and duties as are assigned or delegated to him by the Board
of Directors of the Employer.  Such assignments, powers and duties may, from
time to time, be modified by the Employer, as the 


<PAGE>

Employer's needs may require. The Employee shall also, at the request of the 
Employer, perform similar services for any Affiliate (as hereinafter defined) 
of the Employer without additional compensation.  The Employee agrees to 
devote all of his business time, skill, attention and best efforts to the 
business of the Employer and its Affiliates in the advancement of the best 
interests of the Employer and its Affiliates.  As used in this Agreement, the 
term "Affiliate" of the Employer means any person or corporation that, 
directly or indirectly through one or more intermediaries, controls or is 
controlled by or is under the control of the Employer.

   4.   COMPENSATION.

        A.   For all services rendered by the Employee to the Employer during
the Employment Period, the Employer shall pay the Employee a salary at the 
rate of One Hundred Thousand Dollars ($100,000) annually.  The compensation 
is to be payable, subject to such withholdings as are required by law, in 
installments in accordance with the Employer's customary payroll practices.

        B.   The Employer will grant to the Employee an option to purchase Two
Hundred Thousand (200,000) shares of its common stock (the "Option") at an 
option price determined by the policies, guidelines, rules and regulations of 
the Vancouver Stock Exchange.  One third of the Option shall vest on each of 
the first, second and third anniversaries of the date of grant and shall 
expire five (5) years from the date of grant.  In the event of a "change of 
control" (defined as ownership of more than 40% of the combined voting power 
of the Employer's then outstanding securities by a "Person," as used in 
Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) 
of the Employer, the Option shall become fully vested and exercisable.

        C.   On approximately September 1, 1994, the Chairman of the Board of
Directors of the Employer will review the Employer's operations and the 
Employee's performance since February 15, 1994 and from such review will 
determine the Employee's eligibility for a bonus of up to Twenty Thousand 
Dollars ($20,000) and additional stock options for up to One Hundred 

                                       2

<PAGE>

Thousand (100,000) shares of the Employer's common stock.  The awarding and 
amount of the bonus and the granting of additional stock options shall be 
subject to approval of the Board of Directors of the Employer and the 
Vancouver Stock Exchange.

   5.   OFFICE FACILITIES.  During the Employment Period, the Employer will
furnish the Employee, without charge, suitable office facilities for the 
purpose of performing his duties hereunder, which facilities shall include 
secretarial, telephone, clerical and support personnel and services and shall 
be similar to those furnished to employees of the Employer having comparable 
positions.

   6.   FRINGE BENEFITS; VACATIONS.  During the Employment Period, the
Employee shall be entitled to participate in or receive benefits under such 
pension, medical and life insurance and other employee benefit plans of the 
Employer which may be in effect from time to time, to the extent he is 
eligible under the terms of those plans, on the same basis as other employees 
of the Employer having comparable positions.  The Employee shall be entitled 
to vacations with pay in accordance with the policies of the Employer in 
effect from time to time.

   7.   EXPENSES.  Subject to such policies regarding expenses and expense
reimbursement as may be adopted from time to time by the Employer and 
compliance therewith by the Employee, the Employee is authorized to incur 
reasonable expenses in the performance of his duties hereunder, and the 
Employer will reimburse Employee for such reasonable out-of-pocket expenses 
upon the presentation by the Employee of an itemized account and receipts 
satisfactory to the Employer.

   8.   TERMINATION.

        A.   If the Employee dies or becomes disabled during the Employment
Period, the Employee's salary and other rights under this Agreement or as an 
employee of the Employer (except for salary and other rights accrued prior 
thereto) shall terminate at the end of the month during which death or 
disability occurs.  For purposes of this Agreement, the Employee shall be 
deemed to be "disabled" if, at any time during the Employment Period, the 
Employee shall have 

                                       3

<PAGE>


been unable to perform the duties of his employment hereunder due to physical 
or mental incapacity for a period of ninety (90) days or any ninety (90) days 
in a period of two hundred seventy (270) days.

        B.   If the Employee fails to perform his duties hereunder or to
comply with any of the provisions hereof or commits any act of misconduct, 
malfeasance, gross negligence or disloyalty, the Employment Period and the 
Employee's salary and other rights under this Agreement as an employee of the 
Employer, subject to 8C below, shall terminate upon written notice from the 
Employer to the Employee, but such termination shall not affect the liability 
of the Employee by reason of his misconduct, malfeasance, gross negligence or 
disloyalty.

        C.   If it is determined that the Employer has terminated the Employee
without cause as determined in accordance with Section 8B above, the Employee 
will not be subject to the provisions of Section 10, COVENANT NOT TO COMPETE, 
herein.

   9.   COVENANTS NOT TO DISCLOSE.  The Employee covenants and agrees that he
will not, at any time during or after the termination of his employment by 
the Employer, communicate or disclose to any person, or use for his own 
account, or advise, discuss with, or in any way assist any other person or 
firm in obtaining or learning about, without the prior written consent of the 
Employer, information concerning any inventions, processes, programs, 
systems, flow charts or equipment used in, or any secret or confidential 
information (including, without limitation, any customer lists or trade 
secrets) concerning, the business and affairs of the Employer or any of its 
Affiliates acquired by the Employee during the term of his employment by the 
Employer.  The Employee further covenants and agrees that he shall retain all 
such knowledge and information concerning the foregoing in trust for the sole 
benefit of the Employer and its Affiliates and their respective successors 
and assigns.

   10.  COVENANT NOT TO COMPETE.  The Employee covenants and agrees that,
during the Employment Period and for a period of one (1) year after the 
voluntary resignation of the Employee or termination for cause as outlined in 
8B herein, he will not directly render services 

                                       4

<PAGE>

or advice to, or be engaged in a business during such one-year period which 
is in competition with the business of the Employer except in the course of 
his employment hereunder or except upon the written consent of the Employer.

   11.  ESSENTIAL NATURE OF COVENANTS.  The covenants of the Employee
contained in Sections 9 and 10 shall be construed as independent of any other 
provision of this Agreement; and the existence of any claim or cause of 
action of the Employee against the Employer or any of its subsidiaries, 
whether predicated on this Agreement or otherwise, shall not constitute a 
defense to the enforcement by the Employer of said covenants.  The Employee 
understands that the covenants contained in Sections 9 and 10 are essential 
elements of the transactions contemplated by this Agreement and, but for the 
agreement of the Employee to Sections 9 and 10, the Employer would not have 
agreed to enter into such transactions.

   12.  REMEDIES.  In the event of a breach or threatened breach by the
Employee of Section 9 or 10, the Employer shall be entitled to a temporary 
restraining order and an injunction restraining the Employee from the 
commission of such breach.  Nothing herein contained shall be construed as 
prohibiting the Employer from pursuing any other remedies available to it for 
such breach or threatened breach, including the recovery of money damages.

   13.  WAIVER OF BREACH.  The waiver by one party of a breach of any
provision of this Agreement by the other party shall not operate or be 
construed as a waiver of any subsequent breach by the other party.

   14.  BINDING EFFECT.  This Agreement shall inure to the benefit of and
shall be binding upon the parties hereto and their respective successors, 
assigns, heirs and legal representatives.  Insofar as the Employee is 
concerned, this Agreement, being personal, cannot be assigned.

   15.  SEVERABILITY.  The invalidity of all or any part of any section of
this Agreement shall not render invalid the remainder of this Agreement or 
the remainder of such section.  If any provision of this Agreement is so 
broad as to be unenforceable, such provision shall be interpreted to be only 
so broad as is enforceable.

                                       5

   16.  COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which shall, when executed, be deemed to be an 
original, but all of which together shall constitute one and the same 
instrument.

   17.  GOVERNING LAW.  This Agreement shall be construed (both as to validity
and performance) and enforced in accordance with and governed by the laws of 
the State of Texas.

   18.  NOTICE.  All Notices which are required or may be given under this
Agreement shall be in writing and shall be deemed to have been duly given

                              EMPLOYMENT AGREEMENT


     THIS EMPLOYMENT AGREEMENT is made effective the 18th day of April, 1994, by
and between ROSETTA TECHNOLOGIES INC., a Wyoming corporation, with principal
offices located at 1310 Ranch Road 620 South, Suite B195, Austin, Texas 
78734-6342 (hereinafter referred to as the "Employer"), and BENJAMIN S. MARZ, a
resident of Austin, Texas (hereinafter referred to as the "Employee").

                              W I T N E S S E T H:

     WHEREAS, the Employer desires to employ the Employee, and the Employee and
Employer desire to enter into an agreement relating to such employment,
outlining the duties and obligations of each:

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein set forth, it is agreed as follows:

     1.   EMPLOYMENT.  The Employer agrees to employ the Employee, and the
Employee agrees to be employed by the Employer, subject to the terms and
conditions set forth herein.

     2.   TERM.  Subject to the provisions hereof, the term of the Employee's
employment by the Employer under this Agreement shall expire May 9, 1995;
provided that such term of employment shall continue thereafter unless and until
terminated by either the Employer or the Employee upon no less than one hundred
twenty (120) days' prior written notice to the other of the desire to terminate
such employment.  The Employee is entitled to severance equal to the average
monthly cash compensation (base salary and commissions) for the 120-day period. 
The term of the Employee's employment hereunder, including any continuation of
the original term, is hereinafter referred to as the "Employment Period."

     3.   POSITION AND DUTIES.  During the Employment Period, the Employee shall
serve as Vice President of Sales of the Employer with such assignments, powers
and duties as are assigned or delegated to him by the President of the Employer.
Such assignments, powers and duties may, from time to time, be modified by the
Employer, as the Employer's needs may 

<PAGE>

require.  The Employee shall also, at the request of the Employer, perform 
similar services for any Affiliate (as hereinafter defined) of the Employer 
without additional compensation.  The Employee agrees to devote all of his 
business time, skill, attention and best efforts to the business of the 
Employer and its Affiliates in the advancement of the best interests of the 
Employer and its Affiliates.  As used in this Agreement, the term "Affiliate" 
of the Employer means any person or corporation that, directly or indirectly 
through one or more intermediaries, controls or is controlled by or is under 
the control of the Employer.

     4.   COMPENSATION.

          A.  For all services rendered by the Employee to the Employer during
the Employment Period, the Employer shall pay the Employee a salary at the rate
of Fifty-one Thousand Dollars ($51,000) per year.  The compensation is to be
payable, subject to such withholdings as are required by law, in installments in
accordance with the Employer's customary payroll practices.  Additionally, non-
refundable sales draws will be extended for six months equal to $4,250 per
month.  After the initial six months, as new product is introduced, a mutually
agreeable commission structure will be established using the first 6 months as a
basis for the new plan, but without regard to minimum commission income if
adequate salable product exists.

          B.   The Employer will grant to the Employee an option to purchase
100,000 shares of its common stock at an option price determined by the
policies, guidelines, rules and regulations of the Vancouver Stock Exchange. 
One fourth of such option shall vest on each of the four anniversaries of the
date of grant and shall expire seven (7) years from the date of grant.  Given
40% or more of the company changes hands to one entity, all options vest at the
time of acquisition.

     5.   OFFICE FACILITIES.  During the Employment Period, the Employer will
furnish the Employee, without charge, suitable office facilities for the purpose
of performing his duties hereunder, which facilities shall include secretarial,
telephone, clerical and support personnel and 


                                       2
<PAGE>

services and shall be similar to those furnished to employees of the Employer 
having comparable positions.

     6.   FRINGE BENEFITS; VACATIONS.  During the Employment Period, the
Employee shall be entitled to participate in or receive benefits under such
pension, medical and life insurance and other employee benefit plans of the
Employer which may be in effect from time to time, to the extent he is eligible
under the terms of those plans, on the same basis as other employees of the
Employer having comparable positions.  The Employee shall be entitled to
vacations with pay in accordance with the policies of the Employer in effect
from time to time.

     7.   EXPENSES.  Subject to such policies regarding expenses and expense
reimbursement as may be adopted from time to time by the Employer and compliance
therewith by the Employee, the Employee is authorized to incur reasonable
expenses in the performance of his duties hereunder, and the Employer will
reimburse the Employee for such reasonable out-of-pocket expenses upon the
presentation by the Employee of an itemized account and receipts satisfactory to
the Employer.

     8.   TERMINATION.

          A.   If the Employee dies or becomes disabled during the Employment
Period, the Employee's salary and other rights under this Agreement or as an
employee of the Employer (except for salary and other rights accrued prior
thereto) shall terminate within 120 days from the end of the month during which
death or disability occurs.  For purposes of this Agreement, the Employee shall
be deemed to be "disabled" if, at any time during the Employment Period, the
Employee shall have been unable to perform the duties of his employment
hereunder due to physical or mental incapacity for a period of ninety (90) days
or any ninety (90) days in a period of two hundred seventy (270) days.

          B.   If the Employee fails to perform his duties hereunder or to
comply with any of the provisions hereof or commits any act of malfeasance,
convicted felony, theft, gross negligence or violation of any company policy,
the Employment Period and the Employee's salary and other rights under this
Agreement as an employee of the Employer, subject to 8C 


                                       3

<PAGE>

below, shall terminate upon written notice from the Employer to the Employee, 
but such termination shall not affect the liability of the Employee by reason 
of his misconduct, malfeasance, gross negligence or disloyalty.

          C.   If it is determined that the Employer has terminated the Employee
without cause as determined in accordance with Section 8B above, the Employee
will not be subject to the provisions of Section 10, COVENANT NOT TO COMPETE,
herein.

     9.   COVENANTS NOT TO DISCLOSE.  The Employee covenants and agrees that he
will not, at any time during or after the termination of his employment by the
Employer, communicate or disclose to any person, or use for his own account, or
advise, discuss with, or in any way assist any other person or firm in obtaining
or learning about, without the prior written consent of the Employer,
information concerning any inventions, processes, programs, systems, flow charts
or equipment used in, or any secret or confidential information (including,
without limitation, any customer lists or trade secrets) concerning, the
business and affairs of the Employer or any of its Affiliates acquired by the
Employee during the term of his employment by the Employer.  The Employee
further covenants and agrees that he shall retain all such knowledge and
information concerning the foregoing in trust for the sole benefit of the
Employer and its Affiliates and their respective successors and assigns.

     10.  COVENANT NOT TO COMPETE.  The Employee covenants and agrees that,
during the Employment Period and for a period of one (1) year after the
voluntary resignation of the Employee or termination for cause as outlined in 8B
herein, he will not directly render services or advice to, or be engaged in a
business during such one-year period, where said business's primary products are
in direct competition with the primary products or services of the Employer,
except in the course of his employment hereunder or except upon the written
consent of the Employer.

     11.  ESSENTIAL NATURE OF COVENANTS.  The covenants of the Employee
contained in Sections 9 and 10 shall be construed as independent of any other
provision of this Agreement; and the existence of any claim or cause of action
of the Employee against the Employer or any of 


                                       4
<PAGE>

its subsidiaries, whether predicated on this Agreement or otherwise, shall not 
constitute a defense to the enforcement by the Employer of said covenants.  The
Employee understands that the covenants contained in Sections 9 and 10 are 
essential elements of the transactions contemplated by this Agreement and, but 
for the agreement of the Employee to Sections 9 and 10, the Employer would not
have agreed to enter into such transactions.

     12.  REMEDIES.  In the event of a breach or threatened breach by the
Employee of Section 9 or 10, the Employer shall be entitled to a temporary
restraining order and an injunction restraining the Employee from the commission
of such breach.  Nothing herein contained shall be construed as prohibiting the
Employer from pursuing any other remedies available to it for such breach or
threatened breach, including the recovery of money damages.

     13.  WAIVER OF BREACH.  The waiver by one party of a breach of any
provision of this Agreement by the other party shall not operate or be construed
as a waiver of any subsequent breach by the other party.

     14.  BINDING EFFECT.  This Agreement shall inure to the benefit of and
shall be binding upon the parties hereto and their respective successors,
assigns, heirs and legal representatives.  Insofar as the Employee is concerned,
this Agreement, being personal, cannot be assigned.

     15.  SEVERABILITY.  The invalidity of all or any part of any section of
this Agreement shall not render invalid the remainder of this Agreement or the
remainder of such section.  If any provision of this Agreement is so broad as to
be unenforceable, such provision shall be interpreted to be only so broad as is
enforceable.

     16.  COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which shall, when executed, be deemed to be an original,
but all of which together shall constitute one and the same instrument.

     17.  GOVERNING LAW.  This Agreement shall be construed (both as to validity
and performance) and enforced in accordance with and governed by the laws of the
State of Texas.

     18.  NOTICE.  All Notices which are required or may be given under this
Agreement shall be in writing and shall be deemed to have been duly given when
delivered in person or 


                                       5

Drive, Austin, Texas 78731, or if to the Employer, at the address listed above,
or to such other address as such party shall have specified by  notice to the 
other party hereto as provided in this section.

     19.  ENTIRE AGREEMENT.  This Agreement constitutes the entire agreement
between the parties hereto and supersedes all prior agreements, understandings
and arrangements, oral or written, between the parties hereto with respect to
the subject matter hereof.

incapacity for a period of ninety (90) days or any ninety (90) days in a period
of two hundred seventy (270) days.

          B.   If the Employee fails to perform his duties hereunder or to
comply with any of the provisions hereof because he is guilty of willful and
gross neglect; gross negligence; committed an act evidencing dishonesty or fraud
or involving moral turpitude; committed an act or course of conduct which
constitutes a felony conviction under state or federal law; or is grossly
inattentive to the duties required in this Agreement, the Employment Period and
the Employee's salary and other rights under this Agreement as an employee of
the Employer, subject to 8D below, shall terminate for cause upon written notice
from the Employer to the Employee, but such termination shall not affect the
liability of the Employee by reason of these 


                                        4

<PAGE>

defined actions.  Notwithstanding the above, Employer must give Employee written
notice of being grossly inattentive to the duties required under this Agreement
in sufficient detail to allow Employee the opportunity to cure the item of

action will take more than five (5) days to implement.

          C.   If, during the initial two (20)-year employment period, the
employment relationship is terminated by Employer other than for "cause" as

benefits calculated for a twenty-four (24)-month period beginning with the first
day of the calendar month immediately following the month in which the
employment relationship was terminated, but to be no less than Three Hundred
Thousand Dollars ($300,000), and such amount shall be payable to Employee within
forty-five (45) days after termination date in cash or wired funds.

          D.   If it is determined that the Employer has terminated the Employee

will not be subject to the provisions of Section 10, COVENANT NOT TO COMPETE,
herein.

     9.   COVENANTS NOT TO DISCLOSE.  The Employee covenants and agrees that he
will not, other than in the ordinary course of business, at any time during or
for one (1) year after the termination of his employment by the Employer,
communicate or disclose to any person, or use for his own account, or advise,
discuss with, or in any way assist any other person or firm in obtaining or
learning about, without the prior written consent of the Employer, information
concerning any inventions, processes, programs, systems, flow charts or
equipment used in, or any secret or confidential information (including, without
limitation, any customer lists or trade secrets) concerning, the business and
affairs of the Employer or any of its Affiliates acquired by the Employee during
the term of his employment by the Employer.  The Employee further covenants and

<PAGE>

     10.  COVENANT NOT TO COMPETE.  The Employee covenants and agrees that,
during the Employment Period and for a period of one (1) year after the

business during such one-year period which is in competition with the business
of the Employer in the geographic area of Employer's business, except in the
course of his employment hereunder or except upon the written consent of the
Employer.

     11.  ESSENTIAL NATURE OF COVENANTS.  The covenants of the Employee
contained in Sections 9 and 10 shall be construed as independent of any other
provision of this Agreement; and the existence of any claim or cause of action
of the Employee against the Employer or any of its subsidiaries, whether
predicated on this Agreement or otherwise, shall not constitute a defense to the
enforcement by the Employer of said covenants.  The Employee understands that
the covenants contained in Sections 9 and 10 are essential elements of the
transactions contemplated by this Agreement and, but for the agreement of the
Employee to Sections 9 and 10, the Employer would not have agreed to enter into
such transactions.

     12.  REMEDIES.  In the event of a breach or threatened breach by the
Employee of Section 9 or 10, the Employer shall be entitled to a temporary
restraining order and an injunction restraining the Employee from the commission
of such breach.  Nothing herein contained shall be construed as prohibiting the
Employer from pursuing any other remedies available to it for such breach or
threatened breach, including the recovery of money damages.

     13.  WAIVER OF BREACH.  The waiver by one party of a breach of any
provision of this Agreement by the other party shall not operate or be construed
as a waiver of any subsequent breach by the other party.

     14.  BINDING EFFECT.  This Agreement shall inure to the benefit of and
shall be binding upon the parties hereto and their respective successors,
assigns, heirs and legal representatives.  Insofar as the Employee is concerned,
this Agreement, being personal, cannot be assigned.

     15.  SEVERABILITY.  The invalidity of all or any part of any section of
this Agreement shall not render invalid the remainder of this Agreement or the
remainder of such section.  If any 


                                        6

<PAGE>

provision of this Agreement is so broad as to be unenforceable, such provision
shall be interpreted to be only so broad as is enforceable.

     16.  COUNTERPARTS.  This Agreement may be executed in any number of
counterparts, each of which shall, when executed, be deemed to be an original,
but all of which together shall constitute one and the same instrument.

     17.  GOVERNING LAW.  This Agreement shall be construed (both as to validity
and performance) and enforced in accordance with and governed by the laws of the
State of Texas.

     18.  NOTICE.  All Notices which are required or may be given under this
Agreement shall be in writing and shall be deemed to have been duly given when
delivered in person or three (3) days after being mailed by registered or
certified first-class mail, postage prepaid, return receipt requested, if to the
Employee at 3107 Toro Ring, Austin, Texas 78746, or if to the Employer, at the
address listed above, or to such other address as such party shall have
specified by notice to the other party hereto as provided in this section.

     19.  ENTIRE AGREEMENT.  This Agreement constitutes the entire agreement
between the parties hereto and supersedes all prior agreements, understandings
and arrangements, oral or written, between the parties hereto with respect to
the subject matter hereof.

                             TANISYS TECHNOLOGY INC.

                             1993 Stock Option Plan
                        (As Amended through May 20, 1996)

     1.   PURPOSE.  This 1993 Stock Option Plan (the "Plan") of Tanisys
Technology, Inc., a Wyoming corporation (the "Company"), for key employees,
directors and consultants of the Company, is intended to advance the best
interest of the Company by providing such persons, who have substantial
responsibility for its management, success, and growth, with additional
incentive and by increasing their proprietary interest in the success of the
Company -- thereby encouraging them to remain in its employ or service.

     2.   ADMINISTRATION.  The Plan shall be administered by the Board of
Directors of the Company (the "Board") or a committee to be appointed by the
Board (such committee or the Board acting as such committee is herein referred
to as the "Committee"); and all questions of interpretation and application of
the Plan, or of options granted hereunder (the "Options"), shall be subject to
the determination, which shall be final and binding, of a majority of the whole
Committee.  The Committee shall consist of not less than two members of the
Board of Directors.  Meetings shall be held at such times and places as shall be
determined by the Committee.  A majority of the members of the Committee shall
constitute a quorum for the transaction of business, and the vote of a majority
of those members present at any meeting shall decide any questions brought
before that meeting.  In addition, the Committee may take any action otherwise
proper under the Plan by the unanimous written consent of its members.  No
member of the Committee shall be liable for any act or omission of any other
member of the Committee or for any act or omission on his or her own part,
including but not limited to the exercise of any power or discretion given to
him or her under the Plan, except those resulting from his or her own gross
negligence or willful misconduct.

     3.   OPTION SHARES.  The shares subject to the Options and other provisions
of the Plan shall be shares of the Company's Common Stock, no par value (the
"Common Stock").  The total amount of the Common Stock with respect to which
Options may be granted shall not exceed in the aggregate 2,600,000 shares;
provided, however, that such aggregate number of shares shall be subject to
adjustment in accordance with the provisions of Paragraph 16 hereof.  Such
shares may be treasury shares or authorized but unissued shares.  In the event
that any outstanding Option granted under the Plan shall expire or terminate,
the shares of Common Stock allocable to the unexercised portion of such Option
may again be subject to an Option under the Plan.

     4.   AUTHORITY TO GRANT OPTIONS.  The Committee may grant the following
Options from time to time as it shall from time to time determine:

          (a)  "Incentive" Stock Options.  The Committee may grant to an
     eligible person an Option or Options to buy a stated number of shares of
     Common Stock under the terms and conditions of the Plan, so that the Option
     or Options will be an "incentive stock option" within the meaning of the
     Internal Revenue Code of 1986 (the "Code").

<PAGE>

          (b)  "Nonqualified" Stock Options.  The Committee may grant to an
     eligible person an Option or Options to buy a stated number of shares of
     Common Stock under the terms and conditions of the Plan, even though such
     Option or Options would not constitute an "incentive stock option" within
     the meaning of the Code. 

Subject only to any applicable limitations set forth in the Plan, the number of
shares of Common Stock to be covered by any Option shall be as determined by the
Committee; provided, however, that no individual may hold options to purchase a
number of shares of Common Stock in excess of five percent (5%) of the number of
issued and outstanding shares of Common Stock on the date of grant.  No tandem
Options may be issued, that is, no Option may be granted the exercise of which
would affect the exercisability of any other outstanding Option held by the
optionee.  The Committee shall, at its discretion, be entitled to grant multiple
or a series of options to a qualified recipient pursuant to this Plan.

     5.   ELIGIBILITY.  The individuals who shall be eligible to participate in
the Plan shall be the key employees, directors and consultants of the Company,
or of any wholly owned subsidiary; provided, however, that no employee of the
Company who would be ineligible to receive an incentive stock Option by reason
of the provisions of Section 422(b)(6) of the Code (relating to ownership of
more than 10% of the total combined voting power of all classes of the Company's
stock) shall be eligible to receive an incentive stock Option under the Plan
unless it complies with Paragraphs 7 and 8 hereof.

     6.   GRANTS TO EMPLOYEES AND AFFILIATES.  All key employees, directors and
consultants of the Company shall be eligible to participate in the Plan and
shall be granted Options as determined by unanimous vote or consent of the
Committee.  In determining the number of shares to be purchasable pursuant to an
Option, the Committee shall consider the following factors: an equitable
distribution of available Options having regard to the number of employees,
directors and consultants, the frequency of optionee turnover, the size of
allocations to existing employees, directors and consultants, and the duties and
qualifications of the optionee.

     7.   OPTION PRICE.  The price at which shares may be purchased pursuant to
Options shall be set at the discretion of the Committee, but in no event shall
be less than fair market value; provided, further, that an individual who owns
more than 10% of the total combined voting power of all classes of the stock of
the Company or of its parent or its subsidiaries shall not be eligible to
receive an incentive stock Option unless, on the date such Option is granted,
the Option price is at least 110% of the fair market value of a share of Common
Stock.

     The term "fair market value" on any day shall mean such amount last
determined in good faith by the Board of Directors of the Company or, in absence
of a determination by the Board, by the Committee; provided, however, that
during such time as the Common Stock is listed on the Vancouver Stock Exchange
("VSE"), the fair market value per share shall be the average closing price of
the Common Stock as quoted on the VSE for the previous two weeks; and provided
further that, if the Common Stock is no longer traded on the VSE and is traded
on the NASDAQ quotation system or is listed on an established U.S. stock
exchange or exchanges, such fair market value shall be deemed to be the closing
price of the Common Stock as reported for 

                                    - 2 -

<PAGE>

that day in THE WALL STREET JOURNAL listing of composite transactions for 
such stock exchange or exchanges, or if no sale of Common Stock shall have 
been made on any stock exchange on that day, on the preceding day on which 
there was a sale of such stock as reported.

     8.   DURATION OF OPTIONS.  No Option shall be exercisable after the
expiration of ten years from the date such Option is granted, and the Committee
in its discretion may provide that an Option shall be exercisable during such
ten-year period or any lesser period of time; provided, however, that an
individual who owns more than 10% of the total combined voting power of all
classes of the stock of the Company or of its parent or subsidiaries shall not
be eligible to receive an incentive stock Option unless it is not exercisable
after the expiration of five years from the date such Option is granted.

     9.   AMOUNT EXERCISABLE.

          (a)  Each Option may be exercised, so long as it is valid and
     outstanding, from time to time in part or as a whole, and subject to
     Paragraph 8 hereof and to such other conditions as the Committee in its
     discretion may provide.  Except in extraordinary circumstances approved by
     the VSE, all Options shall vest on an equal basis over a period not less
     than three years from the date of grant. 
     
          (b) The foregoing provision notwithstanding, an individual may not be
     granted incentive stock Options so that the aggregate fair market value
     (determined at the time of grant) of the stock with respect to which
     incentive stock Options are exercisable for the first time by such
     individual during any calendar year under all plans of the Company and its
     parent and subsidiary corporations exceeds $100,000. 

          (c)  Without limiting the authority of the Committee under Paragraph
     9(a), if there is a change in the control of the Company while any Option
     remains outstanding under the Plan, then the Committee may waive any
     limitations set forth in or imposed pursuant to Paragraph 9(a) hereof so
     that any or all Options shall be exercisable in full.  For the purposes of
     the Plan, a "change in control" of the Company shall mean a change in
     control of a nature that is reportable in response to Item 5(f) of Schedule
     14A of Regulation 14A promulgated under the Securities Exchange Act of 1934
     (the "Exchange Act") as in effect on the date hereof, provided that,
     without limitation, such a change in control shall be deemed to have
     occurred if:  (i) any "person" (as such term is used in Sections 13(d) and
     14(d)(2) of the Exchange Act) that does not own, directly or indirectly,
     any shares of the Company's capital stock on the date of adoption of this
     Plan is or becomes the beneficial owner, directly or indirectly, of
     securities of the Company representing 20% or more of the combined voting
     power of the Company's then outstanding securities; or (ii) during any
     period of two consecutive years, individuals who at the beginning of such
     period constitute the Board of Directors of the Company cease for any
     reason to constitute at least a majority thereof. 

     10.  EXERCISE OF OPTIONS. Options shall be exercised by the delivery of
written notice to the Company setting forth the number of shares with respect to
which the Option is to be 

                                    - 3 -

<PAGE>

exercised and specifying the address to which the certificates for such 
shares are to be mailed, together with full payment of the Option price of 
such shares and such other items as may be required pursuant to Paragraph 13 
hereof.  "Full payment" shall mean the full exercise price in cash, certified 
check, bank draft, or postal or express money order payable to the order of 
the Company.  As promptly as practicable after receipt of such written 
notification and payment, the Company shall deliver to the optionee 
certificates for the number of shares with respect to which such Option has 
been so exercised, issued in the optionee's name; provided, that such 
delivery shall be deemed effected for all purposes when a stock transfer 
agent of the Company shall have deposited such certificates in the United 
States mail, addressed to the optionee, at the address specified pursuant to 
this Paragraph 10.  The delivery of certificates upon the exercise of Options 
may, in the discretion of the Committee, be conditioned upon payment to the 
Company by the person exercising such Option of the amount, determined by the 
Company, of any tax liability resulting from such exercise, including, but 
not limited to, employment taxes required to be withheld.

     11.  TRANSFERABILITY OF OPTIONS; STOCK TRANSFER RESTRICTIONS.  Options
shall not be transferable by the optionee otherwise than by will or under the
laws of descent and distribution and shall be exercisable, during his or her
lifetime, only by him or her.

     12.  TERMINATION OF EMPLOYMENT OR DEATH OF OPTIONEE.  Except as may be
otherwise expressly provided herein, Options shall terminate on the earlier of
the date specified pursuant to Paragraph 8 hereof or no later than thirty (30)
days following severance of the employment relationship or termination of
affiliation between the Company and the optionee for any reason, for or without
cause, other than death or disability.  Whether authorized leave of absence or
absence on military or government service constitute severance of the employment
relationship or termination of affiliation between the Company and the optionee
shall be determined by the Committee at the time thereof.  In the event of
termination because of the death or disability of the holder of an Option before
the date of expiration of such Option, such Option shall terminate on the
earlier of such date of expiration or one year following the date of such death.
In the event of such termination, the optionee shall have the right, prior to
the termination of such Option, to exercise the Option to the extent to which he
or she was entitled to exercise such Option immediately prior to such severance
of the employment relationship or termination of affiliation.  After the death
of the optionee, his or her executors, administrators, or any person or persons
to whom his or her Option may be transferred, by will or by the laws of descent
and distribution, shall have the right at any time prior to such termination to
exercise the Option, in whole or in part (without regard to any limitations set
forth in or imposed pursuant to Paragraph 9(a) hereof).  In the event that the
Committee grants an Option designating it as an incentive stock Option, and the
optionee's employment status changes, but such person continues as a director or
consultant of the Company, then the Company in its discretion may, upon request
of the optionee, elect that the Option previously granted shall continue in full
force and effect as a nonqualified stock Option.  In the event that the
Committee grants an Option designating it as a nonqualified stock Option, and
the person's status with the Company or its subsidiary corporations changes, but
such person continues as a key employee, director or consultant of the Company,
then the Option previously granted shall continue in full force and effect,
unless the Committee in its discretion may elect to terminate or modify the
Option.  The Committee shall be permitted, in its discretion, 

                                    - 4 -

<PAGE>

to grant to any employee an Option which is an incentive stock Option or a 
nonqualified stock Option with a provision that the Option shall continue in 
full force and effect as a non-qualified stock Option if the person's status 
with the Company or its subsidiary changes, but such person continues as a 
director or consultant of the Company.  For the purpose of determining the 
employment relationship between the Company and the optionee, employment by a 
wholly owned subsidiary shall be considered employment by the Company.

     13.  REQUIREMENTS OF LAW.

          (a)  The Company shall not be required to sell or issue any shares
     pursuant to any Option if the issuance of such shares shall constitute a
     violation by the optionee or the Company of any provisions of any law or
     regulation of any governmental authority.  If a registration statement
     under the Securities Act of 1933 and any applicable state securities or
     Blue Sky laws (the "Securities Laws") is not in effect with respect to the
     shares of Common Stock issuable pursuant to any Option, the Company may
     require the optionee to make certain representations and may require an
     opinion of counsel satisfactory to the Company to the effect that such
     registration is not required.  Any determination in this connection by the
     Committee shall be final, binding, and conclusive. 

          (b)  Upon exercise of any Option, the Company shall not be required to
     issue such shares unless the Committee has received evidence satisfactory
     to it to the effect that the holder of such Option will not transfer such
     shares except pursuant to a registration statement in effect under the
     Securities Laws or unless an opinion of counsel satisfactory to the Company
     has been received by the Company to the effect that such registration is
     not required.  Any determination in this connection by the Committee shall
     be final, binding, and conclusive. 

          (c)  In the event the shares issuable upon exercise of an Option are
     not registered under the Securities Laws, the Company may imprint the
     following legend or any other legend that counsel for the Company considers
     necessary or advisable to comply with the Securities Laws: 

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED OR QUALIFIED UNDER THE FEDERAL SECURITIES ACT OF
          1933 (THE "1933 ACT") OR THE APPLICABLE STATE SECURITIES
          LAWS AND ARE "RESTRICTED SECURITIES" WITHIN THE MEANING OF
          RULE 144 PROMULGATED UNDER THE 1933 ACT.  THE SECURITIES MAY
          NOT BE SOLD OR TRANSFERRED WITHOUT COMPLYING WITH RULE 144,
          IN THE ABSENCE OF EFFECTIVE REGISTRATION UNDER THE 1933 ACT
          OR OTHER COMPLIANCE UNDER THE 1933 ACT AND APPLICABLE STATE
          SECURITIES LAWS.

     Such legend shall not be required if the shares issued upon exercise of an
     Option are not subject to the Securities Laws. 

                                    - 5 -

<PAGE>

          (d)  The Company may, but shall in no event be obligated to, register
     any securities covered hereby pursuant to the Securities Laws, and in the
     event any shares are so registered, the Company may remove any legend on
     certificates representing such shares.  The Company shall not be obligated
     to take any other affirmative action in order to cause the exercise of an
     Option or the issuance of shares pursuant thereto to comply with any law or
     regulation of any governmental authority. 

     14.  NO RIGHTS AS STOCKHOLDER.  No optionee shall have rights as a
stockholder with respect to shares covered by his or her Option until the date
of issuance of a stock certificate for such shares; no adjustment for dividends
(other than stock dividends under Paragraph 16) or otherwise shall be made if
the record date therefor is prior to the date of issuance of such certificate.  

     15.  EMPLOYMENT OBLIGATIONS.  The granting of any Option shall not impose
upon the Company any obligation to employ or continue to employ any optionee,
and the right of the Company to terminate the employment of any officer or other
employee shall not be diminished or affected by reason of the fact that an
Option has been granted to him or her.

     16.  CHANGES IN THE COMPANY'S CAPITAL STRUCTURE.  The existence of
outstanding Options shall not affect in any way the right or power of the
Company or its stockholders to make or authorize any or all adjustments,
recapitalizations, reorganizations, or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or any
issue of bonds, debentures, preferred, or prior preference stock ahead of or
affecting the Common Stock or the rights thereof, or the dissolution or
liquidation of the Company, or any sale or transfer of all or any part of its
assets or business, or any other corporate act or proceeding whether of a
similar character or otherwise.

     If, while there are outstanding Options, the Company shall effect a
subdivision or consolidation of shares or other capital readjustment, the
payment of a stock dividend, or other increase or reduction of the number of
shares of the Common Stock outstanding without receiving compensation therefor
in money, services, or property, then:  (i) in the event of an increase in the
number of shares outstanding, the number of shares of Common Stock then subject
to Options hereunder shall be proportionately increased, and the cash
consideration payable per share shall be proportionately reduced; (ii) in the
event of a reduction in the number of such shares outstanding, the number of
shares of Common Stock then subject to Options hereunder shall be
proportionately reduced, and the cash consideration payable per share shall be
proportionately increased; and (iii) the number of shares then available for
Options hereunder shall be proportionately increased or decreased, as the case
may be.

     After a merger of one or more corporations into the Company, each holder of
an outstanding Option shall, at no additional cost, be entitled upon exercise of
such Option to receive (subject to any required action by stockholders) in lieu
of the number of shares as to which such Option shall then be so exercisable,
the number and class of shares of stock or other securities to which such holder
would have been entitled pursuant to the terms of the agreement 

                                    - 6 -

<PAGE>

of merger if, immediately prior to such merger, such holder had been the 
holder of record of a number of shares of Common Stock equal to the number of 
shares as to which such Option shall be so exercised.

     If the Company is merged into or consolidated with another corporation
under circumstances where the Company is not the surviving corporation or where
the Company will be a wholly owned subsidiary of another corporation, or if the
Company sells or otherwise disposes of all or substantially all of its property
or assets to another corporation while unexercised Options remain outstanding
under the Plan, then:  (i) subject to the provisions of clause (ii) below, after
the effective date of such merger, consolidation, or sale, as the case may be,
each holder of an outstanding Option shall be entitled, upon exercise of such
Option, to receive, in lieu of shares of Common Stock, the number and class of
shares of such stock, other securities, cash, and other property or rights as
the holders of shares of Common Stock received pursuant to the terms of the
merger, consolidation, or sale and to which he or she would have been entitled
if, immediately prior to such merger, consolidation, or sale, he or she had been
the holder of record of a number of shares of Common Stock equal to the number
of shares as to which such Option shall be so exercised; and (ii) all
outstanding Options may be canceled by the Board of Directors of the Company as
of the effective date of any such merger, consolidation, or sale, provided that
(x) written notice of such cancellation is given to each holder of an Option not
later than 30 days prior to such effective date and (y) each holder of an Option
shall have the right to exercise such Option in full (without regard to any
limitations set forth in or imposed pursuant to Paragraph 9(a) hereof) during
the said 30-day period preceding the effective date of such merger,
consolidation, or sale.

     No adjustment provided for in this Paragraph 16 shall be made if such
adjustment would result in a modification of any incentive stock Option or cause
such incentive stock Option to fail to qualify as an "incentive stock option"
under the Code.

     Except as hereinbefore expressly provided, the issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, for cash or property, or for labor or services, either upon direct
sale or upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of shares or obligations of the Company convertible into such shares
or other securities, shall not affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock then
subject to outstanding Options.

     17.  SUBSTITUTE OPTIONS.  Incentive stock Options may be granted under this
Plan from time to time in substitution for incentive stock options held by
employees of other corporations who are about to become employees of the Company
as the result of a merger or consolidation of the employing corporation with the
Company, or the acquisition by the Company of substantially all the assets of
the employing corporation, or the acquisition by the Company of the issued and
outstanding stock of the employing corporation as the result of which it becomes
a wholly owned subsidiary of the Company.  The terms and conditions of the
substitute incentive stock Options so granted may vary from the terms and
conditions set forth in this Plan to such extent as the Board of Directors of
the Company at the time of grant may deem appropriate to conform, 

                                    - 7 -

<PAGE>

in whole or in part, to the provisions of the incentive stock options in 
substitution for which they are granted, but no such variation shall be such 
as to affect the status of any such substitute Option as an "incentive stock 
option" under the Code.

     18.  AMENDMENT OR TERMINATION OF PLAN.  The Board of Directors may modify,
revise, or terminate this Plan at any time and from time to time; provided,
however, that without the further approval both of the holders of at least a
majority of the outstanding shares of Common Stock and of a majority of the
outstanding shares of Common Stock held by the disinterested shareholders of the
Company (as defined by the VSE), the Board may not: (i) increase the aggregate
number of shares which may be issued under Options and pursuant to the
provisions of the Plan; (ii) reduce the Option price at which an incentive stock
Option may be granted to an amount less than the fair market value per share at
the time such Option is granted; (iii) change the class of employees eligible to
receive Options; (iv) materially modify the requirements as to affiliate
eligibility for participation in the Plan; (v) materially increase the benefits
accruing to participants under the Plan; or (vi) effect an amendment that would
cause incentive stock Options issued pursuant to the Plan to fail to meet the
requirements of "incentive stock options" as defined in Section 422 of the Code;
provided, however, that the Board shall have the power to make such changes in
the Plan and in the regulations and administrative provisions hereunder or in
any outstanding Option as in the opinion of counsel for the Company may be
necessary or appropriate from time to time to enable any incentive stock Options
granted pursuant to the Plan to continue to qualify as "incentive stock options"
under the Code and the regulations which may be issued thereunder as in
existence from time to time.

     19.  WRITTEN AGREEMENT.  Each Option granted hereunder shall be embodied in
a written option agreement that shall be subject to the terms and conditions
prescribed above, and shall be signed by the optionee and by the Chairman of the
Board, the President or any Vice President of the Company for and in the name
and on behalf of the Company.  Such an option agreement shall contain such other
provisions as the Committee in its discretion shall deem advisable.

     20.  INDEMNIFICATION OF COMMITTEE.  The Company shall indemnify each
present and future member of the Committee against, and each member of the
Committee shall be entitled without further act on his or her part to indemnity
from the Company for, all expenses (including the amount of judgments and the
amount of approved settlements made with a view to the curtailment of costs of
litigation, other than amounts paid to the Company itself) reasonably incurred
by him or her in connection with or arising out of any action, suit, or
proceeding in which he or she may be involved by reason of his or her being or
having been a member of the Committee, whether or not he or she continues to be
such member of the Committee at the time of incurring such expenses; provided,
however, that such indemnity shall not include any expenses incurred by any such
member of the Committee (i) in respect of matters as to which he or she shall be
finally adjudged in any such action, suit, or proceeding to have been guilty of
gross negligence or willful misconduct in the performance of his or her duty as
such member of the Committee or (ii) in respect of any matter in which any
settlement is effected, to an amount in excess of the amount approved by the
Company on the advice of its legal counsel; and provided further, that no right
of indemnification under the provisions set forth herein shall be available to

                                    - 8 -

<PAGE>

or enforceable by any such member of the Committee unless, within sixty (60) 
days after institution of any such action, suit, or proceeding, he or she 
shall have offered the Company, in writing, the opportunity to handle and 
defend same at its own expense.  The foregoing right of indemnification shall 
inure to the benefit of the heirs, executors, or administrators of each such 
member of the Committee and shall be in addition to all other rights to which 
such member of the Committee may be entitled as a matter of law, contract, or 
otherwise.

     21.  EFFECTIVE DATE OF PLAN.  The Plan shall become effective and shall be
deemed to have been adopted October 25, 1993 if, within one year of that date,
it shall have been approved by the holders of at least a majority of the
outstanding Common Stock.  No Option shall be granted pursuant to the Plan after
October 24, 2003.

[ADDRESS 1]
[ADDRESS 2]

Dear [FIRST NAME]:

     Under the terms and conditions of the 1993 Stock Option Plan (the "Plan")
of Tanisys Technology, Inc., a Wyoming corporation (the "Company"), a copy of
which is attached hereto and incorporated herein by reference, the Company
hereby grants to you the option to purchase [NO. OF SHARES] shares of the
Company's Common Stock, no par value, at the price of U.S. $[PRICE] per share,
subject to adjustment as provided in the Plan.  This option shall constitute a
"nonqualified" option within the meaning of Paragraph 4(b) of the Plan.

     This option may be exercised only in the manner prescribed by Paragraph 10
of the Plan as follows:

          1.   [1/3 OF SHARES] shares subject to option hereunder are
     exercisable after one year from the date hereof;

          2.   [1/3 OF SHARES] shares subject to option hereunder are
     exercisable after two years from the date hereof; and

          3.   [1/3 OF SHARES] shares subject to option hereunder are
     exercisable after three years from the date hereof,

provided to the extent not exercised, such installments shall accumulate and be
exercisable, in whole or in part, in any subsequent period, subject to
termination of this option.

     This option shall be for a term commencing on the date hereof and ending
[EXPIRATION DATE], provided that this option shall terminate on the earlier of
such expiration date or upon termination of employment or other relationship
with the Company as set forth in Paragraph 12 of the Plan.  This option is not
assignable or transferable otherwise than by will or under the laws of descent
and distribution.


<PAGE>
     The optionee hereby accepts and agrees to be bound by all the terms and
conditions of the Plan.  The optionee hereby represents that he or she is a(n)
[DIRECTOR, EMPLOYEE, CONSULTANT] of the Company.

     Notwithstanding anything to the contrary herein, this option shall not be
exercisable and the Company shall not be required to issue any shares hereunder
unless (a) a registration statement under the Securities Act of 1933 and any
applicable state securities or "blue sky" laws is in effect with respect to the
shares of common stock covered by this option, or (b) unless in the opinion of
counsel for the Company such registration is not then required.

     This letter agreement and the Plan constitute and express the entire
agreement of the parties with respect to the option.  This option shall be
subject to and shall comply with the rules and regulations of the Vancouver
Stock Exchange, the Securities Act of British Columbia, and its securities
regulatory authorities as long as the common stock of the Company is listed on
the Vancouver Stock Exchange.

                              Very truly yours,

                              TANISYS TECHNOLOGY, INC.

          or are not paid for more than 500 hours.  If you go into the military
          service of the United States, you are considered terminated as long as
          you return to work within the time required by law.  If you separate
          from employment and incur a Break in Service, all contributions to
          your various accounts are suspended. [See special rules relating to
          maternity and paternity leave below.  Also see Section VI(B) to
          determine your eligibility to share in the Employer's Contribution if
          you separate from employment, but do not incur a Break in Service.] 
          If a Break in Service occurs and you return to full time employment
          with the Employer, your rights are explained in the section entitled
          "Vesting".

     C.   COMPENSATION.  Your total salary, pay, or earned income from the
          Employer, as reflected on tax Form W-2, which is subject to
          withholding when earned.  Compensation will include amounts received
          by you during the Plan Year.  Compensation shall be limited to
          $150,000 as adjusted for inflation.

          Compensation shall include amounts deferred under 401(k) plans,
          Section 125 cafeteria plans and certain other plans of deferred
          compensation.  Compensation shall be limited to Compensation earned
          while a Participant.

     D.   DISABILITY.  A potentially permanent illness or injury, as certified
          to by a physician who is approved by the Employer, which prevents you
          from engaging in work for which you are qualified for a period of at
          least 12 months.

     E.   EARLY RETIREMENT.  You may retire early upon reaching age 55 and
          completion of 0 Years of Service.  If you terminate employment after
          completing the required number of Years of Service, but before
          attaining the required age, you may elect Early Retirement after
          attaining the required age.

     F.   EFFECTIVE DATE.  The date on which the Plan starts or an amendment is
          effective.

     G.   ELECTIVE DEFERRAL.  Employer contributions made to the Plan at your
          election, instead of being given to you in cash as part of your
          salary.  You can elect to defer a portion of your salary, instead of
          receiving it in cash, and your Employer will contribute it to the Plan
          on your behalf.

     H.   ENTRY DATE.  The date on which you enter the Plan.  Your Entry Date
          will be the earlier of the first day of the Plan Year or the first day
          of the seventh month of the Plan Year coinciding with or following the
          date on which you satisfy the eligibility requirements.

     I.   FAMILY MEMBER.  The Spouse or lineal ascendant or descendant (or
          Spouse thereof) of either a more than 5% owner of the Employer or one
          of the ten highest compensated Highly Compensated Employees of the
          Employer.


                                          2

<PAGE>

     J.   HIGHLY COMPENSATED EMPLOYEE.  Any Employee who during the current or
          prior Plan Year (1) was a more than 5% owner, (2) received more than
          $75,000 in Compensation as adjusted for inflation (3) received more
          than $50,000 in Compensation as adjusted for inflation and was in the
          top 20% of Employees when ranked by Compensation, or (4) was an
          officer receiving more than $45,000 in Compensation as adjusted for
          inflation.  Family Members of any 5% owner, or Highly Compensated
          Employee in the group of the ten Employees with the greatest
          Compensation, will be combined as if they were one person for purposes
          of Compensation and contributions.  If you are not currently or never
          were Highly Compensated, or a Family Member of a Highly Compensated
          Employee, you are a non-Highly Compensated Employee.

     K.   HOUR OF SERVICE.  You will receive credit for each hour you are (1)
          paid for being on your job, (2) paid even if you are not at work
          (vacation, sickness, leave of absence, or Disability), or (3) paid for
          back pay if hours were not already counted.  A maximum of 501 hours
          will be credited in any year for periods during which you are not at
          work but are paid.  Hours of Service will be calculated based on
          actual hours.

     L.   MATERNITY/PATERNITY LEAVE.  You may be eligible for additional Hours
          of Service if you leave employment, even if temporarily, due to
          childbirth or adoption.  If this is the case, you will be credited
          with enough hours (up to 501) of service to prevent a Break in
          Service, either in the year you leave employment or the following
          year.  For example, if you have 750 Hours of Service in the year that
          your child is born, you would not get any more hours credited for that
          Plan Year since you do not have a Break in Service.  Therefore, if you
          do not return to employment the following year, you will get 501 Hours
          of Service so you will not have a Break in Service in that year. 
          Alternatively, if you do return the following year, but work only 300
          hours, you will receive an additional 201 hours in order to prevent a
          break.  These Hours of Service for maternity or paternity leave must
          all be used in one Plan Year.  They are used only to prevent a Break
          in Service and not for calculating your Years of Service for
          eligibility, vesting or benefits.

     M.   NORMAL RETIREMENT AGE.  The attainment of age 65.

     N.   SPOUSE.  The person to whom you are or were legally married, or your
          common law spouse if common law marriage is recognized by the state in
          which you live.  In order for your Spouse to receive a benefit under
          this Plan, he or she may not predecease you.  A former spouse may be
          treated as a "Spouse" under this definition if recognized as such
          under a Qualified Domestic Relations Order as explained at Section
          XV(F) of this Summary Plan Description.

     O.   TAXABLE WAGE BASE.  The amount of your Compensation subject to FICA
          tax on the first day of each Plan Year.


                                          3

     have to satisfy the age and Service requirements specified above.

V    EMPLOYEE CONTRIBUTIONS

     A.   ELECTIVE DEFERRALS

          You, as an eligible Employee, may authorize the Employer to withhold
          from 0% up to 15% of your Compensation, not to exceed $7,000 as
          adjusted for inflation, and to deposit such amount in the Plan trust. 
          If you participate in a similar plan of an unrelated employer and your
          Elective Deferrals under this Plan and the other plan exceed the
          $7,000 limit, for a given year you must designate one of the Plans as
          receiving an excess amount.  If you choose this Plan as the one
          receiving the excess, you must notify the Plan Administrator by March
          1 of the following year so that the excess and any income thereon may
          be returned to you by April 15.  You may increase, decrease, or
          terminate your Elective Deferral percentage on the first day of each
          month of the Plan Year.


                                          4

<PAGE>

          If you stop your contributions, you may not start deferring again for
          a period of 1 months.  The Employer may also reduce or terminate your
          withholdings if required to maintain the Plan's qualified status.

     B.   ROLLOVER AND TRANSFER CONTRIBUTIONS

          Rollover and Transfer contributions are permitted.  You may make a
          Rollover or Transfer Contribution prior to becoming a Participant.  An
          Employer can refuse to allow Transfer Contributions to its
          profit-sharing Plan if the transfer will affect the Plan's ability to
          offer lump sum distributions as the normal form of distribution.

          A rollover or transfer of your retirement benefits may originate from
          another qualified retirement plan or special individual retirement
          arrangement (known as a "conduit" IRA) to this Plan.  If you have
          already received a lump-sum payment from another qualified retirement
          plan, or if you received payment from another qualified plan and
          placed it in a separate "conduit" IRA, you may be eligible to
          redeposit that payment to this Plan.  The last day you may make a
          Rollover Contribution to this Plan is the 60th day after you receive
          the distribution from the other plan or IRA.  A transfer occurs when
          the trustee of the old plan transfers your assets to this Plan.  If
          you believe you qualify for a transfer or rollover, see the Plan
          Administrator for more details.

VI   EMPLOYER CONTRIBUTIONS

     A.   CONTRIBUTION FORMULA

          ELECTIVE DEFERRALS:

          The Employer will contribute all Compensation which you elect to defer
          to the Plan within the limits outlined in Section V(A).

          MATCHING CONTRIBUTIONS:

          The Employer may make a Matching Contribution to each Participant
          based on his or her Elective Deferrals in a percentage set by the
          Employer prior to the end of each Plan Year.  The Employer shall not
          match your Elective Deferrals that are in excess of 6% of your
          Compensation.

          The time period which will be used for determining the amount of
          Matching Contributions owed shall be annually.

          The Employer has the right to designate all or a portion of the
          Matching Contributions as "Qualified."  To the extent Matching
          Contributions are so


                                          5

<PAGE>

          designated, they are nonforfeitable and may not be withdrawn from the
          Plan prior to separation from Service or attainment of age 59-1/2.

          Employer Matching Contributions will only be made on Elective
          Deferrals made to the Plan.  Elective Deferrals withdrawn prior to the
          end of the Plan Year will not receive Matching Contributions.

          QUALIFIED NON-ELECTIVE CONTRIBUTIONS:

          The Employer may also contribute an additional amount determined in
          its sole judgment.  This additional contribution, if any, will be
          allocated to only non-Highly Compensated Participants, in proportion
          to each eligible Employee's Compensation as a ratio of all eligible
          Employees' Compensation.  These Contributions will be nonforfeitable
          and subject to withdrawal restrictions.

          DISCRETIONARY:

          The Employer may also contribute an additional amount determined in
          its sole judgment.  Such additional contribution, if any, shall be
          allocated to each Participant in proportion to his or her Compensation
          for the Plan Year earned while a Participant.  A Participant will also
          receive an allocation with respect to his or her Compensation in
          excess of the Taxable Wage Base.

     B.   ELIGIBILITY FOR ALLOCATION

          The Employer's Contribution will be made to all Participants who are
          employed at the end of the Plan Year provided that the Participant has
          completed a Year of Service during the Plan Year.  The Employer shall
          also make matching and other related contributions as indicated below
          to Employees who terminate during the Plan Year as a result of:

          Matching    Other

          X           X       (i)     Retirement.
          X           X       (ii)    Disability.
          X           X       (iii)   Death.

                              (iv)    Other termination of employment provided
                                      that the Participant has completed 1000
                                      Hours of Service.
                              (v)     Other termination of employment without
                                      regard to the number of Hours of Service
                                      the Participant has completed.
                              (vi)    Termination of employment (for any
                                      reason) provided that the Participant has
                                      completed 1000 Hours of Service.

VII  GOVERNMENT REGULATIONS

     The federal government sets certain limitations on the level of
     contributions which may be made to a Plan such as this.  There is also a
     "percentage" limitation which means that the percentage of Compensation
     which you may contribute (both Elective Deferrals and, if applicable,
     Voluntary Contributions) depends on the average percentage of Compensation
     that the other Participants are contributing.  Simply stated, all
     Participants are divided into 2 categories.  Highly Compensated and
     non-Highly Compensated.  The average contribution for each group is
     calculated and compared.  If a Highly Compensated Participant is
     contributing more than he or she is allowed, the excess plus or minus any
     gain or loss will be returned.  Keep in mind that if you are a 5% owner of
     the business or one of the ten highest paid Highly Compensated employees,
     you will be combined with your Family Members for the purpose of
     calculating such percentages.

VIII PARTICIPANT ACCOUNTS

     The Employer will set up a recordkeeping account in your name to show the
     value of your retirement benefit.  The Employer will make the following
     additions to your account:

     A.   your allocated share of the Employer's Contribution (including your
          Elective Deferrals).

     B.   the amount of your Transfer Contributions and Rollover Contributions,
          if any, and

     C.   your share of investment earnings and appreciation in the value of
          investments.

     The Employer will make the following subtractions from your account:

     D.   any withdrawals or distributions made to you, and

     E.   your share of investment losses and depreciation in the value of
          investments.

     F.   your share of administrative fees and expenses paid out of the Plan,
          if applicable.

     The Employer will value your account daily and will provide you with a
     statement of account activity at least once annually.

IX   VESTING

     A.   DETERMINING VESTED BENEFIT

          Vesting refers to your earning or acquiring a nonforfeitable right to
          the full amount of your account.  Any Elective Deferrals, Qualified
          Non-Elective Contributions, Qualified Matching Contributions, Rollover
          Contributions,


                                          7

<PAGE>

          Transfer Contributions, plus or minus any earnings or losses, are
          always 100% vested and cannot be forfeited for any reason.  Any
          contribution not listed in the previous sentence, and the earnings or
          losses thereon, will vest in accordance with the following table:

                                YEARS OF SERVICE
        ----------------------------------------------------------------
           1         2         3         4         5         6         7
        ----      ----      ----      ----      ----      ----      ----
          10%      20%        40%      60%      100%


          You are considered to have completed 1 Year of Service for purposes of
          vesting upon the completion of 1000 Hours of Service at any time
          during a Plan Year.

          You automatically become fully vested, regardless of the vesting
          table, upon attainment of Normal Retirement Age, Early Retirement Age,
          upon retirement due to Disability, upon death, and upon termination of
          the Plan.

     B.   PAYMENT OF VESTED BENEFIT

          If you separate from Service before your retirement, death or
          Disability, you may request early payment of your vested benefit by
          submitting a written request to the Plan Administrator.  If you vested
          account balance at the time of termination or at the time of any prior
          distributions exceeds or exceeded $3,500, you may defer the payment of
          your benefit until April 1 of the calendar year following the calendar
          year during which you attain age 70-1/2.  The Employer will
          immediately pay any vested benefit not in excess of $3,500.  The
          portion of your account balance to which you are not vested is called
          a "forfeiture" and remains in the Plan to reduce the Employer's
          Contribution for the year.

     C.   LOSS OF BENEFITS

          There are only two events which can cause the loss of all or a portion
          of your account.  One is termination of employment before your are
          100% vested according to the vesting provisions described at IX(A) and
          the other is a decrease in the value of your account from investment
          losses or administrative expenses and other costs of maintaining the
          Plan.

     D.   REALLOCATION OF FORFEITURE

          If you receive the vested portion of your account upon separation from
          service, the Employer will forfeit and reallocate the nonvested
          portion of your account.  If you have not received a distribution of
          your vested balance, your nonvested portion will be forfeited at the
          end of the Plan Year during which you incur your fifth consecutive
          1-year Break in Service.


                                          8

<PAGE>

     E.   REEMPLOYMENT

          If you terminate service with your Employer, then later become
          reemployed, you will become a Participant as of the next Entry Date
          [see Section III] upon returning to employment.  If you are not a
          member of an eligible class and later become a member of the eligible
          class, you shall participate immediately if you have satisfied the
          minimum age and service requirements.  Should you become ineligible to
          participate because you are no longer a member of an eligible class,
          you shall participate upon your return to an eligible class.  All
          years of prior Service will be counted when calculating your vested
          percentage in your new account balance.  The following rules apply in
          connection with reemployed Participants.

          (a)  TERMINATED PARTIALLY VESTED PARTICIPANTS.  If you terminate
               employment and receive payment of your partially vested interest
               and are reemployed prior to incurring five consecutive one-year
               Breaks in Service, you have the right to buy back the non vested
               portion of your account if it was forfeited.  If your non vested
               balance was not forfeited it will still be part of your account
               and the buy back is not necessary.  If a buy back is necessary to
               regain the forfeiture, you must redeposit the amount paid to you
               without interest within five years of your date of reemployment. 
               If you do not repay the amount you received, the nonvested
               portion of your Employer account will be permanently forfeited. 
               Whether you repay or not, your prior Service will count toward
               vesting service for future Employer contributions.

               FOR EXAMPLE, assume that you quit your job with your current
               Employer.  At the time of termination you had completed four
               Years of Service and had accrued a total benefit of $10,000 under
               the retirement play.  Although this amount had been allocated to
               your account, you were only 40% vested in that amount when you
               left.  You decided to take a distribution of your vested account
               balance (40% of $10,000, or $4,000) when you quit.  The nonvested
               balance of your account ($6,000) was forfeited.  Three years
               later, you became reemployed by the same Employer.  Since you
               were reemployed within 5 years, you have the right to repay the
               $4,000 distribution you received when you quit.  You would have
               to repay the $4,000 within 5 years of being rehired.  If you do
               so, the nonvested portion of your account ($6,000) which was
               forfeited when you left will be restored to your account.  After
               restoration, you will be vested in 40% of this account, but your
               vested percentage will increase based on your Years of Service
               after your reemployment.  Your prior Service will ALWAYS count
               towards vesting of Employer Contributions which you will receive
               after reemployment, whether or not you decide to repay and
               restore your prior account.


                                          9

<PAGE>

               (b)  Terminated Non-Vested Participants.  If you were not vested
                    in any portion of your Employer Contribution account prior
                    to your separation from service and are reemployed before
                    incurring five consecutive one-year Breaks in Service, you
                    will be credited for vesting with all pre-break and
                    post-break service.  Your prior account balance will
                    automatically be restored and will continue to vest in that
                    account.  If you are reemployed after incurring five
                    consecutive one-year Breaks in Service, you will lose your
                    prior account balance, but your pre-break Years of Service
                    will count towards vesting, in your new account balance.

X.   TOP HEAVY RULES

     A "top-heavy" plan is one in which more than 60% of the contributions or
     benefits are attributable to certain "key employees," such as owners,
     officers and stockholders.  The Plan Administrator is responsible for
     determining each year if the Plan is "top-heavy." If the Plan becomes
     top-heavy, special rules apply to the allocation of the Employer's
     contribution.  These special rules require that only Participants who are
     not key employees will generally receive an allocation of the Employer's
     contribution equal to 3% of Compensation, or if less, the greatest
     percentage allocated to the account of any key employee.  All participants
     are entitled to receive a minimum allocation upon completing at least one
     Hour of Service in the top-heavy Plan Year provided they are employed on
     the last day of the Plan Year.  The Employer's minimum contribution can be
     satisfied by another Employer sponsored retirement plan, if so elected by
     the Employer.  The following vesting schedule shall apply for the Plan Year
     the Plan becomes top-heavy, for any type of Employer Contribution, unless
     the Employer has already elected a faster schedule:

                                YEARS OF SERVICE

           1         2         3         4         5         6
        ----      ----      ----      ----      ----      ----
         0%        20%        40%      60%        80%      100%


XI   RETIREMENT BENEFITS AND DISTRIBUTIONS

     A.   RETIREMENT BENEFITS

          The full value of your account balance is payable at your Normal
          Retirement Age, even if you continue to work, or you may defer payment
          until April 1 following the year you reach age 70-1/2.  If you work
          beyond your Normal Retirement Age, you will continue to fully
          participate in the Plan.


                                          10

<PAGE>

     B.   DISTRIBUTIONS DURING EMPLOYMENT

          Upon the completion of five Years of Service, benefits attributable to
          Employer contributions, allocated to your account(s), are available
          for withdrawal.

          If applicable, benefits attributable to your Voluntary contributions
          under the Plan plus any rollovers are available for withdrawal upon
          request to the Plan Administrator.  Transfers Contributions may be
          withdrawn only if they originate from plans meeting certain safe
          harbor provisions.

     C.   HARDSHIP WITHDRAWALS

          You may file a written request for a hardship withdrawal of the
          portion of your account balance attributable to Elective Deferrals and
          certain Employer Contributions to the extent vested.  You must
          generally have your Spouse's written consent for a hardship withdrawal
          unless you are advised otherwise by the Plan Administrator.  Prior to
          receiving a hardship distribution, you must take any other
          distribution and borrow the maximum non-taxable loan amount allowed
          under this and other plans of the Employer.  Note, however, that if
          the effect of the loan would be to increase the amount of your
          financial need, you are not required to take the loan.  For example,
          if you needs funds to purchase a principal residence, and a plan loan
          would disqualify you from obtaining other necessary financing, you do
          not have to take the loan.  Hardship withdrawals may be authorized by
          the Employer for the following reasons:

          (a)  to assist you in purchasing a personal residence which is your
               primary place of residence (not including mortgage payments),

          (b)  to assist you in paying tuition expenses for you, your Spouse, or
               your dependents, for the next twelve months of post-secondary
               education,

          (c)  to assist you in paying certain expenses incurred or necessary on
               behalf of you, your Spouse, or your dependents for
               hospitalization, doctor or surgery expenses which are not covered
               by insurance, or

          (d)  to prevent your eviction from or foreclosure on your principal
               residence.

          Any hardship distribution is limited to the amount needed to meet the
          financial need.  Hardship withdrawals must be approved by the Employer
          and will be administered in a non-discriminatory manner.  Such
          withdrawals will not affect your eligibility to continue to
          participate in Employer Contributions to the Plan.  Your right to make
          Voluntary Contributions and Elective Deferrals will be suspended for
          twelve months.  Any withdrawals you receive under these rules may not
          be recontributed to the Plan and may be subject to taxation, as well
          as an additional 10% penalty tax if the withdrawal is received before
          you reach age 59-


                                          11

<PAGE>


          1/2.  These payments shall also be subject to a mandatory 20%
          withholding for income tax purposes.

     D.   BENEFICIARY

          Every Participant or former Participant with benefits may designate a
          person or persons who are to receive benefits under the Plan in the
          event of his or her death.  The designation must be made on a form
          provided by and returned to the Plan Administrator.  You may change
          your designation at any time.  If you are married, your beneficiary
          will automatically be your Spouse.  If you and your Spouse wish to
          waive this automatic designation, you must complete a beneficiary
          designation form.  The form must be signed by you and, if applicable,
          your Spouse in front of a Plan representative or a Notary Public.

     E.   DEATH BENEFITS

          In the event of your death, the full value of your account is payable
          to your beneficiary in a lump sum.

     F.   FORM OF PAYMENT

          When benefits become due, you or your representative should apply to
          the Employer requesting payment of your account and specifying the
          manner of payment.  The normal or automatic form of payment is a lump
          sum.

     G.   ROLLOVER OF PAYMENT

          If your benefits qualify as eligible rollovers, you have the option of
          having them paid directly to you, when they become due, or having them
          directly rolled over to another qualified plan or an IRA.  If you do
          not choose to have the benefits directly rolled over, the Plan is
          required to automatically withhold 20% of your payment for tax
          purposes.  If you do choose to have the payment made to you, you still
          have the option of rolling over the payment yourself to a qualified
          plan or an IRA within sixty days (first check with a tax advisor to
          make sure it is an eligible rollover).  However, 20% of your payment
          will still be withheld.  The following example illustrates how this
          works:

          For example, if you have $100,000 in your vested account balance and
          choose to have the payment of your benefits made directly to an IRA or
          another qualified play, the entire $100,000 will be transferred to the
          trustee of the other plan or the IRA, and you will treat the entire
          amount as a rollover on your tax return so that you will not pay taxes
          on the entire amount.  If you choose not to have the account
          transferred directly to an IRA or qualified plan, 20% or $20,000 will
          automatically be withheld from your payment.  Thus, you will receive
          only $80,000 as a distribution of your benefits.  In order to roll the
          entire amount over


                                          12

<PAGE>

          into your IRA, you would have to come up with $20,000 out of your own
          pocket to make up the difference.  If this is done, the $20,000 which
          was withheld may be returned when you file your taxes at the end of
          the year.  However, if you are unable to produce the extra cash, the
          rollover amount will only be $80,000, and the other $20,000 which was
          withheld will be treated as taxable income to you.  If you are under
          age 59-1/2 when you receive your benefit payment, the withheld amount
          will also be subject to the 10% early distribution penalty.

          Certain benefit payments are not eligible for rollover and therefore
          will also not be subject to the 20% mandatory withholding.  They are
          as follows:

               1.   installments paid over life;
               2.   installments for a period of at least 10 years; and
               3.   minimum required distributions at age 70-1/2.

          There are also several operational exceptions and a "de minimis"
          exception for payments of less than $200.  Also Employee Voluntary
          contributions are not eligible for rollover.

     H.   TIME OF PAYMENT

          If you retire, become disabled, or die, payments will start as soon as
          administratively feasible following the date on which a distribution
          is requested by you or is otherwise payable.

          If you terminate for a reason other than death, Disability, or
          retirement, payments will start as soon as administratively feasible
          following the date on which a distribution is requested by you or is
          otherwise payable.

XII  INVESTMENTS

     A.   ALTERNATIVE INVESTMENTS/INVESTMENT DIRECTION UNDER A TRUST FUND

          The monies contributed to the Plan may be invested in any security or
          form of property considered prudent for a retirement plan.  Such
          investments include common and preferred stocks, exchange traded put
          and call options, bonds, money market instruments, mutual funds,
          savings accounts, certificates of deposit, Treasury bills, or
          insurance contracts.  An institutional Trustee may invest in its own
          deposits or those of affiliates which bear a reasonable interest rate,
          or in a group of collective trust maintained by such Trustee.

     B.   INVESTMENT RESPONSIBILITY

          The Plan's assets are held by the Trustee who is identified in Section
          II of this Summary.  The Trustee is responsible for the safekeeping of

          and move monies from one fund to another in accordance with the rules
          established by the Plan Administrator.

     D.   PARTICIPANT LOANS

          Participant loans are permitted under the Plan.  In order to get a
          loan from the Plan, you must make application to the Plan

          are subject to a strict set of rules established by law.  The rules
          are covered in a separate Loan Application Form and Promissory Note
          Form.  These Forms are available from the Plan Administrator.

          (d)  any other duties necessary and as agreed upon.

XIV  AMENDMENT AND TERMINATION

     The Employer may amend the Plan at any time, provided that no amendment
     will divert any part of the Plan's assets to any purpose other than for the
     exclusive benefit of you and the other Participants in the Plan or
     eliminate an optional form of distribution.  The Employer may also
     terminate the Plan.  In the event of an actual Plan termination, all
     amounts credited to your account will be fully vested and will be paid to
     you.  Depending on the facts and circumstances, a partial termination may
     be found to occur where a significant number of Employees are terminated by
     the Employer or excluded from Plan participation.  In case of a partial
     termination, only those affected will become 100% vested.

XV   LEGAL PROVISIONS

     A.   RIGHTS OF PARTICIPANTS

          As a Plan Participant, you have certain rights and protection under
          the Employee Retirement Income Security Act of 1974 (ERISA).  The law
          says that you are entitled to:

          (a)  Examine, without charge, all documents relating to the operation
               of the Plan and any documents filed with the U.S.  Department of
               Labor.  These documents are available for review in the
               Employer's offices during regular business hours.

          (b)  Obtain copies of all Plan documents and the other Plan
               information upon written request to the Employer.  The Employer
               may make a reasonable charge for producing the copies.

          (c)  Receive from the Employer at least once each year a summary of
               the Plan's annual financial report.

          (d)  Obtain, at least once a year, a statement of the total benefits
               accrued for you, and your nonforfeitable (vested) benefits, if
               any.  The Plan provides that you will receive this statement
               automatically.  If you are not vested, you may request a
               statement showing the date when you will begin to vest in your
               account.

          (e)  File suit in a federal court, if any materials requested are not
               received within 30 days of your request, unless the materials
               were not sent because of matters beyond the control of the
               Employer.  If you are improperly


                                          16

<PAGE>

               denied access to information you are entitled to receive, the
               Employer may be required to pay up to $100 for each day's delay
               until the information is provided to you.

     B.   FIDUCIARY RESPONSIBILITY

          ERISA also imposes obligations upon the persons who are responsible
          for the operation of the Plan.  These persons are referred to as
          "fiduciaries." Fiduciaries must act solely in you interest as a Plan
          Participant and they must exercise prudence in the performance of
          their duties.  Fiduciaries who violate ERISA may be removed and
          required to reimburse any losses they have caused you or other
          Participants in the Plan.

     C.   EMPLOYMENT RIGHTS

          Participation in the Plan is not a guarantee of employment.  However,
          the Employer may not fire you or discriminate against you to prevent
          you from becoming eligible for the Plan or from obtaining a benefit or
          exercising your rights under ERISA.

     D.   BENEFIT INSURANCE

          Your benefits under this Plan are not insured by the Person Benefit
          Guaranty Corporation since the law does not require plan termination
          insurance for this type of plan.

     E.   CLAIMS PROCEDURE

          If you feel you are entitled to a benefit under the Plan, mail or
          deliver your written claim to the Plan Administrator.  The Plan
          administrator will notify you, your beneficiary, or authorized
          representative of the action taken within 60 days of receipt of the
          claim.  If you believe that you are being improperly denied a benefit
          in full or in part, the Employer must give you a written explanation
          of the reason for the denial.  If the Employer denies your claim, you
          may, within 60 days after receiving the denial, submit a written
          request asking the Employer to review your claim for benefits.  Any
          such request should be accompanied by documents or records in support
          of your appeal.  You, your beneficiary, or your authorized
          representative may review pertinent documents and submit issues and
          comments in writing.  If you get no satisfaction from the Employer,
          you have the right to request assistance from the U.S.  Department of
          Labor or you can file suit in a state or federal court.  Service of
          legal process may be made upon the Plan Trustee or the Plan
          Administrator.  If you are successful in your lawsuit, the court may
          require the Employer to pay your legal costs, including your
          attorney's fees.  If you lose, and the court finds that your claim is
          frivolous, you may be required to pay the Employer's legal fees.


                                          17

     F.   ASSIGNMENT

          Your rights and benefits under this Plan cannot be assigned, sold,
          transferred or pledged by you or reached by your creditors or anyone
          else except under a qualified domestic relations order (QDRO) is a
          court order issued under state domestic relations law relating to
          divorce, legal separation, custody, or support proceedings.  The QDRO
          recognizes the right of someone other than you to receive your Plan
          benefits.  You will be notified if a QDRO relating to your Plan
          benefits is received.  Receipt of a qualified domestic relations order
          shall allow for an earlier than normal distribution to the person(s)
          other than the Participant listed in the order.

     G.   QUESTIONS

          If you have any questions about this statement of your rights under
          ERISA, please contact the Employer or the nearest Area Office of the
          U.S.  Labor-Management Service Administration, Department of Labor.

     H.   CONFLICTS WITH PLAN

          This booklet is not the Plan document, but only a Summary Plan
          Description of its principal provisions and not every limitation or
          detail of the Plan is included.  Every attempt has been made to
          provide concise and accurate information.  However, if there is a
          discrepancy between this booklet and the official Plan document, the
          Plan document shall prevail.

                                   LEASE AGREEMENT

THIS LEASE AGREEMENT is made and entered into by and between AEtna Life
Insurance Company, hereinafter referred to as  "Landlord", and 1st Tech
Corporation, hereinafter referred to as  "Tenant."

1.  PREMISES AND TERM.  In consideration of the mutual obligations of Landlord
and Tenant set forth herein, Landlord leases to Tenant, and Tenant hereby takes
from Landlord, certain leased premises situated within the County of Travis,
State of Texas, as more particularly described on EXHIBIT "A" attached hereto
and incorporated herein by reference (the "Premises"), to have and to hold,
subject to the terms, covenants and conditions in this Lease.  The term of this
Lease shall commence on the Commencement Date hereinafter set forth and shall
end on the last day of the month that is Sixty (60) months after the
Commencement Date.

    A.   EXISTING BUILDING AND IMPROVEMENTS.  If no material improvements are
to be constructed to the Premises, the "Commencement Date" shall be April 26,
1993.  In such event, Tenant acknowledges that (i) it has inspected and accepts
the Premises in its "as is" condition, (ii) the buildings and improvements
comprising the same are suitable for the purpose for which the Premises are
leased, (iii) the Premises are in good and satisfactory condition, and (iv) no
representations as to the repair of the Premises nor promises to alter, remodel
or improve the Premises have been made by Landlord ( unless otherwise expressly
set forth in this Lease).

2.  BASE RENT, SECURITY DEPOSIT AND ESCROW DEPOSITS.

    A.   BASE RENT. Tenant agrees to pay Landlord rent for the Premises, in
advance, without demand, deduction or set off, at the rate of SEE MONTHLY RENTAL
ON EXHIBIT "C" and /100 Dollars ($) per month during the term hereof.  One such
monthly installment, plus the other monthly charges set forth in Paragraph 2C
below, shall be due and payable on the date hereof, and like monthly installment
shall be due and payable on or before the first day of each calendar month
succeeding the Commencement Date, except that all payments due hereunder for any
fractional calendar month shall be prorated.

    B.   SECURITY DEPOSIT.  In addition, Tenant agrees to deposit with Landlord
on the date hereof the sum of Four Thousand Seven Hundred Seventy-three and
60/100 Dollars ($4,773.60), which shall be held by Landlord, without obligation
for interest, as security for the performance of Tenant's obligations under this
Lease (the "Security Deposit"), it being expressly understood and agreed that
the Security Deposit is not an advance rental deposit or a measure of Landlord's
damages in case of Tenant's default.  Upon occurrence of an Event of Default,
Landlord may use


<PAGE>

all or part of the Security Deposit to pay past due rent or other payments due
Landlord under this Lease or the cost of any other damage, injury, expense or
liability caused by such Event of Default, without prejudice to any other remedy
provided herein or provided by law.  On demand, Tenant shall pay Landlord the
amount that will restore the Security Deposit to its original amount.  The
Security Deposit shall be deemed the property of Landlord, but any remaining
balance of the Security Deposit shall be returned by Landlord to Tenant when all
of Tenant's present and future obligations under this Lease have been fulfilled.

    C.   ESCROW DEPOSITS. Without limiting in any way Tenant's other
obligations under this Lease, Tenant agrees to pay to Landlord its Proportionate
Share (as defined in this Paragraph 2C below) of (i) Taxes (hereinafter defined)
payable by Landlord pursuant to Paragraph 3A below, (ii) the cost of utilities
payable by Landlord pursuant to Paragraph 8 below, (iii) Landlord's cost of
maintaining insurance pursuant to Paragraph 9A below, and (iv) Landlord's cost
of maintaining the Premises pursuant to paragraph 5E below and any common area
charges payable by Tenant in accordance with Paragraph 4B below (collectively,
the "Tenant Costs").  During each month of the term of this Lease, on the same
day that rent is due hereunder, Tenant shall deposit in escrow with Landlord an
amount equal to one-twelfth (1/12) of the estimated amount of Tenant's
Proportionate Share of the Tenant Costs.  Tenant authorizes Landlord to use the
funds deposited with Landlord under this Paragraph 2C to pay such Tenant Costs. 
The initial monthly escrow payments are based upon the estimated amounts for the
year in question and shall be increased or decreased annually to reflect the
projected actual amount of all Tenant Costs.  If the Tenant's total escrow
deposits for any calendar year are less than Tenant's actual Proportionate Share
of the Tenant Costs for such calendar year, Tenant shall pay the difference to
Landlord within ten (10) days after demand.  If the total escrow deposits of
Tenant for any calendar year are more than Tenant's actual Proportionate Share
of the Tenant Costs for such calendar year, Landlord shall retain such excess
and credit it against Tenant's escrow deposits next maturing after such
determination.  In the event the Premises constitute a portion of a multiple
occupancy building (the "Building"), Tenant's "Proportionate Share" with respect
to the Building, as used in this Lease, shall mean a fraction, the numerator of
which is the gross rentable area contained in the Premises and the denominator
of which is the gross rentable area contained in the entire Building.  In the
event the Premises or the Building is part of a project or business park owned,
managed or leased by Landlord or an affiliate of Landlord (the "Project"),
Tenant's "Proportionate Share" of the Project, as used in this Lease, shall mean
a fraction, the numerator of which is the gross rentable area contained in the
Premises and the denominator of which is the gross rentable area contained in
all of the buildings (including the Building) within the project. 

3.  TAXES

    A.   REAL PROPERTY TAXES.     Subject to reimbursement under Paragraph 2C
herein, Landlord agrees to pay all taxes, assessments and governmental charges
of any kind and nature (collectively referred to herein as "Taxes") that accrue
against the Premises, the Building and/or the land of which the Premises or the
Building are a part.  If at any time during the term of this Lease there shall
be levied, assessed or imposed on Landlord a capital levy or other tax directly


                                          3

<PAGE>

on the rents received therefrom and/or a franchise tax, assessment, levy or
charge measured by or based, in whole or in part, upon such rents from the
Premises and/or the land and improvements of which the Premises are a part, then
all such taxes, assessments, levies or charges, or the part thereof so measured
or based shall be deemed to be included within the term "Taxes" for the purposes
hereof.  The Landlord shall have the right to employ a tax consulting firm to
attempt to assure a fair tax burden on the real property within the applicable
taxing jurisdiction.  Tenant agrees to pay its Proportionate Share of the cost
to such consultant.

    B.   PERSONAL PROPERTY TAXES.  Tenant shall be liable for all taxes levied
or assessed against any personal property or fixtures placed in or on the
Premises.  If any such taxes are levied or assessed against Landlord or
Landlord's property and (i) Landlord pays the same or (ii) the assessed value of
Landlord's property is increased by inclusion of such personal property and
fixtures and Landlord pay the increased taxes, then Tenant shall pay to

    B.   RAILROAD SPUR.  Tenant agrees to maintain any spur track servicing the
Premises and to sign a joint maintenance agreement with the railroad company
servicing the Premises if requested by the railroad company.  Landlord shall
have the right to coordinate all repairs and maintenance of any rail tracks
serving or intended to serve the Premises and, if Tenant uses such rail tracks,

Proportionate Share of the costs of such repairs and maintenance and any other
sums specified in any agreement respecting such  tracks to which Landlord is a
party. 

    C.   PARKING.  Tenant and its employees, customers and licenses shall have

days of the date Tenant takes possession of the Premises.

    E.   OPTION TO MAINTAIN PREMISES.  Landlord reserves the right to perform,
in whole or in part and without notice to Tenant, maintenance, repairs and
replacements to the Premises, paving, common area, landscape, exterior painting,
common sewage line plumbing and any other items that are otherwise Tenant's
obligations under this Paragraph 5, in which event, Tenant shall be liable for
its Proportionate Share of the cost and  expense of such repair, replacement,
maintenance and other such items.

6.  ALTERATIONS.  Tenant shall not make any alterations, additions or
improvements to the Premises without the prior written consent of Landlord. 
Tenant, at its own cost and expense, may erect such shelves, bins, machinery and
trade fixtures as it desires, provided that (i) such items do not alter the
basic character of the Premises or the Building, (ii) such items do not overload
or damage same, (iii) such items may be removed without injury to the Premises,
and (iv) the construction, erection or installation thereof complies with all

this Lease.  All shelves, bins, machinery and trade fixtures installed by Tenant
shall be removed on or before the earlier to occur of the day of termination or
expiration of this Lease or vacating the Premises, at which time Tenant shall
restore the Premises to their original condition.  All alterations,
installations, removals and restorations shall be performed in a good and
workmanlike manner so


                                          5

<PAGE>

as not to damage or alter the primary structure or structural qualities of the
Building or other improvements situated on the Premises or of which the
Premises are a part. 

7.  SIGNS.  Any signage Tenant desires for the Premises shall be subject to
Landlord's written approval and shall be submitted to Landlord prior to the
Commencement Date of this Lease.  Tenant shall repair, paint and/or replace the
Building fascia surface to which its signs are attached upon Tenant's vacating
the Premises or the removal or alteration of its signage.  Tenant shall not,
without Landlord's prior written consent, (i) make any changes to the exterior
of the Premises, such as painting; (ii) install any exterior lights,
decorations, balloons, flags, pennants or banners; or (iii) erect or install any
signs, windows or door lettering, placards, decorations or advertising media of
any type which can be viewed from the exterior of the Premises.  All signs,

bars or other security installations visible from outside the Premises shall
conform in all respects to the criteria established by Landlord or shall be
otherwise subject to Landlord's prior written consent.

8.  UTILITIES.  Landlord agrees to provide normal water and electricity service
to the Premises.  Tenant shall pay for all water, gas, heat, light, power,
telephone, sewer, sprinkler charges and other utilities and services used on or
at the Premises, together with any taxes, penalties, surcharges or the like
pertaining to the Tenant's use of the Premises and any maintenance charges for
utilities.  Landlord shall have the right to cause any of said services to be
separately metered to Tenant, at Tenant's expense.  Tenant shall pay its pro
rata share, as reasonably determined by Landlord, of all charges for jointly
metered utilities.  Landlord shall not be liable for any interruption or failure
of utility service on the Premises, and Tenant shall have no rights or claims as
a result of any such failure.  In the event water is not separately metered to
Tenant, Tenant agrees that it will not use water and sewer capacity for uses
other than normal domestic restroom and kitchen usage, and Tenant further agrees
to reimburse Landlord for the entire amount of common water and sewer costs as
additional rental if, in fact, Tenant uses water or sewer capacity for uses
other than normal domestic restroom and kitchen uses without first obtaining
Landlord's written permission, including but not limited to the cost for
acquiring additional sewer capacity to service Tenant's excess sewer use. 
Furthermore, Tenant agrees in such event to install at its own expense a
submeter to determine Tenant's usage.

9.  INSURANCE

    A.   LANDLORD'S INSURANCE.  Subject to reimbursement under Paragraph 2C
herein, Landlord shall maintain insurance covering the Building in an amount not
less than eighty percent (80%) of the "replacement cost" thereof, insuring
against the perils of fire, lightning, extended coverage, vandalism and
malicious mischief.

    B.   TENANT'S INSURANCE.  Tenant, at its own expense, shall maintain during
the term of this Lease a policy or policies of workers' compensation and
comprehensive general liability insurance, including personal injury and
property damage, with contractual liability endorsement, in the amount of Five
Hundred Thousand Dollars ($500,000.00) for property damage and One Million
Dollars ($1,000,000.00) per occurrence and One Million Dollars ($1,000,000.00)
in the



                                          6

<PAGE>

aggregate for personal injuries or deaths of persons occurring in or about the
Premises.  Tenant, at its own expense, shall also maintain during the term of
this Lease fire and extended coverage insurance covering the replacement cost of
(i) all alterations, additions, partitions and improvements installed or placed
on the Premises by Tenant or by Landlord on behalf of Tenant; and (ii) all of
Tenant's personal property contained within the Premises.  Said policies shall
(i) name the Landlord as an additional insured and insure Landlord's contingent
liability under or in connection with this Lease (except for the workers'
compensation policy, which instead shall include a waiver of subrogation
endorsement in favor of Landlord); (ii) be issued by an insurance company which
is acceptable to Landlord; and (iii) provide that said insurance shall not be
cancelled unless thirty (30) days' prior written notice has been given to
Landlord.  Said policy or policies or certificates thereof shall be delivered to
Landlord by Tenant on or before the Commencement Date and upon each renewal of
said insurance.

    C.   PROHIBITED USES.  Tenant will not permit the Premises to be used for
and purposes or in any manner that would (i) void the insurance thereon, (ii)
increase the insurance risk or cost thereof, or (iii) cause the disallowance of
any sprinkler credits; including without limitation, use of the Premises for the
receipt, storage or handling of any product, material or merchandise that is
explosive or highly inflammable.  If any increase in the cost of any insurance
on the Premises or the Building is caused by Tenant's use of the Premises or
because Tenant vacates the Premises, then Tenant shall pay the amount of such
increase to Landlord upon demand therefor.

10. FIRE AND CASUALTY DAMAGE.

    A.   TOTAL OR SUBSTANTIAL DAMAGE AND DESTRUCTION.  If the Premises or the
Building should be damaged or destroyed by fire or other peril, Tenant shall
immediately give written notice to Landlord of such damage or destruction.  If
the Premises or the Building should be totally destroyed by any peril covered by
the insurance to be provided by Landlord under Paragraph 9A above, or if they
should be so damaged thereby that, in Landlord's estimation, rebuilding or
repairs cannot be completed within one hundred eighty (180) days after the date
of such damage or after such completion there would not be enough time remaining
under the terms of this Lease to fully amortize such rebuilding or repairs, then
this Lease shall terminate and the rent shall be abated during the unexpired
portion of this Lease, effective upon the date of the occurrence of such damage.

    B.   PARTIAL DAMAGE OR DESTRUCTION.  If the Premises or the Building should
be damaged by any peril covered by the insurance to be provided by Landlord
under Paragraph 9A above and, in Landlord's estimation, rebuilding or repairs
can be substantially completed within one hundred eighty (180) days after the
date of such damage, then this Lease shall not terminate and Landlord shall
substantially restore the Premises to its previous condition, except that
Landlord shall not be required to rebuild, repair or replace any part of the
partitions, fixtures, additions and other improvements that may have been
constructed, erected or installed in or about the Premises for the benefit of,
by or for Tenant.

    C.   LIENHOLDERS' RIGHTS IN PROCEEDS.  Notwithstanding anything herein to
the contrary, in the event the holder of any indebtedness secured by a mortgage
or deed of trust


                                          7

<PAGE>

covering the Premises requires that the insurance proceeds be applied to such
indebtedness, then Landlord shall have the right to terminate this Lease by
delivering written notice of termination to Tenant within fifteen (15) days
after such requirement is made known to Landlord by any such holder, whereupon
all rights and obligations hereunder shall cease and terminate.

    D.   WAIVER OF SUBROGATION.  Notwithstanding anything in this Lease to the
contrary, Landlord and Tenant hereby waive and release each other of and from
any and all rights of recovery, claims, actions or causes of action against each
other, or their respective agents, officers and employees, for any  loss or
damage that may occur to the Premises, improvements to the Building or personal
property (Building contents) within the Building and/or Premises, for any reason
regardless of cause or origin.  Each party to this Lease agrees immediately
after execution of this Lease to give written notice of the terms of the mutual
waivers contained in this subparagraph to each insurance company that has issued
to such party policies of fire and extended coverage insurance and to have the
insurance policies properly endorsed to provide that the carriers of such
policies waive all rights of recovery under subrogation or otherwise against the
other party. 

11. LIABILITY AND INDEMNIFICATION.  Except for any claims, rights of recovery
and causes of action that Landlord has released, Tenant shall hold Landlord
harmless from and defend Landlord against any and all claims or liability for
any injury or damage (i) to any person or property whatsoever occurring in, on
or about the Premises or any part thereof, the Building and/or other common
areas, the use of which Tenant may have in accordance with this Lease, if (and
only if) such injury or damage shall be caused in whole or in part by the act,
neglect, fault or omission of any duty by Tenant, its agents, servants,
employees or invitees; (ii) arising from the conduct or management of any work
done by the Tenant in or about the Premises; (iii) arising from transactions of
the Tenant; and (iv) all costs, counsel fees, expenses and liabilities incurred
in connection with any such claim or action or proceeding brought thereon.  The
provisions of this Paragraph 11 shall survive the expiration or termination of
this Lease.  Landlord shall not be liable in any event for personal injury or
loss of Tenant's property caused by fire, flood, water leaks, rain, hail, ice,
snow, smoke, lightning, wind, explosion, interruption of utilities or other
occurrences.  Landlord strongly recommends that Tenant secure Tenant's own
insurance in excess of the amounts required elsewhere in this Lease to protect
against the above occurrences if Tenant desires additional coverage for such
risks.  Tenant shall give prompt notice to Landlord of any significant accidents
involving injury to persons or property.  Furthermore, Landlord shall not be
responsible for lost or stolen personal property, equipment, money or jewelry
from the Premises or from the public areas of the Building or the Project,
regardless of whether such loss occurs when the area is locked against entry. 
Landlord shall not be liable to Tenant or Tenant's employees, customers or
invitees for any damages or losses to persons or property caused by any lessees
in the Building or the Project, or for any damages or losses caused by theft,
burglary, assault, vandalism or other crimes.  Landlord strongly recommends that
Tenant provide its own security systems and services and secure tenant's own
insurance in excess of the amounts required elsewhere in this Lease to protect
against the above occurrences if Tenant desires additional protection or
coverage for such risks.  Tenant shall give Landlord prompt notice of any
criminal or suspicious conduct within or about the Premises, the Building or the
Project and/or


                                          8

<PAGE>

any personal injury or property damage caused thereby.  Landlord may, but is not
obligated to, enter into agreements with third parties for the provision,
monitoring, maintenance and repair of any courtesy patrols or similar services
or fire protective systems and equipment and, to the extent same is provided at
Landlord's sole discretion, Landlord shall not be liable to Tenant for any
damages, costs or expenses which occur for any reason in the event any such
system or equipment is not properly installed, monitored or maintained or any
such services are not properly provided.  Landlord shall use reasonable
diligence in the maintenance of existing lighting, if any, in the parking garage
or parking areas servicing the Premises, and Landlord shall not be responsible
for additional lighting or any security measures in the Project, the Premises,
the parking garage or other parking areas.

12. USE.  The Premises shall be used only for the purpose of receiving,
storing, shipping and selling (other than retail) products, materials and
merchandise made and/or distributed by Tenant and for such other lawful purposes
as may be directly incidental thereto.  Outside storage, including without
limitation storage of trucks and other vehicles, is prohibited without
Landlord's prior written consent.  Tenant shall comply with all governmental
laws, ordinances and regulations applicable to the use of the Premises and shall
promptly comply with all governmental orders and directives for the correction,
prevention and abatement of nuisances in, upon or connected with the Premises,
all at Tenant's sole expense.  Tenant shall not permit any objectionable or
unpleasant odors, smoke, dust, gas, noise or vibrations to emanate from the
Premises, nor take any other action that would constitute a nuisance or would
disturb, unreasonably interfere with or endanger Landlord or any other lessees
of the Building or the Project.

13. HAZARDOUS WASTE.  The term "Hazardous Substances", as used in this Lease,
shall mean pollutants, contaminants, toxic or hazardous wastes, radioactive
materials or any other substances, the use and/or the removal of which is
required or the use of which is restricted, prohibited or penalized by any
"Environmental Law", which term shall mean any federal, state or local statute,
ordinance, regulation or other law of a governmental or quasi-governmental
authority relating to pollution or protection of the environment or the
regulation of the storage or handling of Hazardous Substances.  Tenant hereby
agrees that:  (i) no activity will be conducted on the Premises that will
produce any Hazardous Substances, except for such activities that are part of
the ordinary course of Tenant's business activities (the "Permitted
Activities"), provided said Permitted Activities are conducted in accordance
with all Environmental Laws and, in connection therewith, Tenant shall be
responsible for obtaining any required permits or authorizations and paying any
fees and providing any testing required by any governmental agency; (ii) the
Premises will not be used in any manner for the storage of any Hazardous
Substances, except for the temporary storage of such materials that are used in
the ordinary course of Tenant's business (the "Permitted Materials"), provided
such Permitted Materials are properly stored in a manner and location meeting
all Environmental Laws and, in connection therewith, Tenant shall be responsible
for obtaining any required permits or authorizations and paying any fees and
providing any testing required by any governmental agency; (iii) no portion of
the Premises will be used as a landfill or a dump; (iv) Tenant will not install
any underground tanks of any type; (v) Tenant will not allow any surface or
subsurface conditions to exist or come


                                          9

<PAGE>

into existence that constitute, or with the passage of time may constitute, a
public or private nuisance; and (vi) Tenant will not permit any Hazardous
Substances to be brought onto the Premises, except for the Permitted Materials,
and if so brought or found located thereon, the same shall be immediately
removed, with proper disposal, and all required clean-up procedures shall be
diligently undertaken by Tenant at its sole cost pursuant to all Environmental
Laws.  Landlord and Landlord's representatives shall have the right but not the
obligation to enter the Premises for the purpose of inspecting the storage, use
and disposal of any Permitted Materials to ensure compliance with all
Environmental Laws.  Should it be determined, in Landlord's sole opinion, that
any Permitted Materials are being improperly stored, used or disposed of, then
Tenant shall immediately take such corrective action as requested by Landlord. 
Should Tenant fail to take such corrective action within twenty four (24) hours,
Landlord shall have the right to perform such work and Tenant shall reimburse
Landlord, on demand, for any and all costs associated with said work.  If at any
time during or after the term of this Lease, the Premises is found to be
contaminated with Hazardous Substances, Tenant shall diligently institute proper
and thorough clean-up procedures, at Tenant's sole cost.  Tenant agrees to
indemnify and hold Landlord harmless from all claims, demands, actions,
liabilities, costs, expenses, damages, penalties and obligations of any nature
arising from or as a result of any contamination of the Premises with Hazardous
Substances, or otherwise arising from the use of the Premises by Tenant.  The
foregoing indemnification and the responsibilities of Tenant shall survive the
termination or expiration of this Lease. 

14. INSPECTION.  Landlord's agents and representatives shall have the right to
enter the Premises at any reasonable time during business hours (or at any time
in case of emergency) (i) to inspect the Premises, (ii) to make such repairs as
may be required or permitted pursuant to this Lease, and/or (iii) during the
last six (6) months of the Lease term, for the purpose of showing the Premises. 
In addition, Landlord shall have the right to erect a suitable sign on the
Premises stating the Premises are available for lease.  Tenant shall notify
Landlord in writing at least thirty (30) days prior to vacating the Premises and
shall arrange to meet with Landlord for a joint inspection of the Premises prior
to vacating.  If Tenant fails to give such notice or to arrange for such
inspection, then Landlord's inspection of the Premises shall be deemed correct
for the purpose of determining Tenant's responsibility for repairs and
restoration of the Premises.

15. ASSIGNMENT AND SUBLETTING.  Tenant shall not have the right to sublet,
assign or otherwise transfer or encumber this Lease, or any interest therein,
without the prior written consent of Landlord.  Any attempted assignment,
subletting, transfer or encumbrance by Tenant in violation of the terms and
covenants of this paragraph shall be void.  Any assignee, sublessee or
transferee of Tenant's interest in this Lease (all such assignees, sublessees
and transferees being hereinafter referred to as "Transferees"), by assuming
Tenant's obligations hereunder, shall assume liability to Landlord for all
amounts paid to persons other than Landlord by such Transferees to which
Landlord is entitled or is otherwise in contravention of this Paragraph 15.  No
assignment, subletting or other transfer, whether or not consented to by
Landlord or permitted hereunder, shall relieve Tenant of its liability under
this Lease.  If an Event of Default occurs while the Premises or any part
thereof are assigned or sublet, then Landlord, in addition to any other remedies
herein provided or provided by law, may collect directly from such Transferee
all


                                          10

<PAGE>

rents payable to the Tenant and apply such rent against any sums due Landlord
hereunder.  No such collection shall be construed to constitute a novation or a
release of Tenant from the further performance of Tenant's obligations
hereunder.  If Landlord consents to any subletting or assignment by Tenant as
hereinabove provided and any category of rent subsequently received by Tenant
under any such sublease is in excess of the same category of rent payable under
this Lease, or any additional consideration is paid to Tenant by the assignee
under any such assignment, then Landlord may, at its option, declare such excess
rents under any sublease or such additional consideration for any assignment to
be due and payable by Tenant to Landlord as additional rent hereunder.  The
following shall additionally constitute an assignment of this Lease by Tenant
for the purposes of this Paragraph 15:  (i) if Tenant is a corporation, any
merger, consolidation, dissolution or liquidation, or any change in ownership or
power to vote of thirty percent (30%) or more of Tenant's outstanding voting
stock; (ii) if Tenant is a partnership, joint venture or other entity, any
liquidation, dissolution or transfer of ownership of any interests totaling
thirty percent (30%) or more of the total interests in such entity; (iii) the
sale, transfer, exchange, liquidation or other distribution of more than thirty
percent (30%) of Tenant's assets, other than this Lease; or (iv) the mortgage,
pledge, hypothecation or other encumbrance of or grant of a security interest by
Tenant in this Lease, or of any of Tenant's rights hereunder.

16. CONDEMNATION.  If more than eighty percent (80%) of the Premises are taken
for any public or quasi-public use under governmental law, ordinance or
regulation, or by right of eminent domain or private purchase in lieu thereof,
and the taking prevents or materially interferes with the use of the remainder
of the Premises for the purpose for which they were leased to Tenant, then this
Lease shall terminate and the rent shall be abated during the unexpired portion
of this Lease, effective on the date of such taking.  If less than eighty
percent (80%) of the Premises are taken for any public or quasi-public use under
any governmental law, ordinance or regulation, or by right of eminent domain or
private purchase in lieu thereof, or if the taking does not prevent or
materially interfere with the use of the remainder of the Premises for the
purpose for which they were leased to Tenant, then this Lease shall not
terminate, but the rent payable hereunder during the unexpired portion of this
Lease shall be reduced to such extent as may be fair and reasonable under all of
the circumstances.  All compensation awarded in connection with or as a result
of any of the foregoing proceedings shall be the property of Landlord, and
Tenant hereby assigns any interest in any such award to Landlord; provided,
however, Landlord shall have no interest in any award made to Tenant for loss of
business or goodwill or for the taking of Tenant's trade fixtures and personal
property, if a separate award for such items is made to Tenant.

17. HOLDING OVER.  At the termination of this Lease by its expiration or
otherwise, Tenant shall immediately deliver possession of the Premises to
Landlord with all repairs and maintenance required herein to be performed by
Tenant completed.  If, for any reason, Tenant retains possession of the Premises
after the expiration or termination of this Lease, unless the parties hereto
otherwise agree in writing, such possession shall be deemed to be a tenancy at
will only, and all of the other terms and provisions of this Lease shall be
applicable during such period, except that Tenant shall pay Landlord from time
to time, upon demand, as rental for the period of such possession, an amount
equal to one and one-half (1 1/2) times the rent if in effect


                                          11

<PAGE>

on the date of such termination of this Lease, computed on a daily basis for
each day of such period.  No holding over by Tenant, whether with or without
consent of Landlord, shall operate to extend this Lease except as otherwise
expressly provided.  The preceding provisions of this Paragraph 17 shall not be
construed as consent for Tenant to retain possession of the Premises in the
absence of written consent thereto by Landlord.

18. QUIET ENJOYMENT.  Landlord represents that it has the authority to enter
into this Lease and that, so long as Tenant pays all amounts due hereunder and
performs all other covenants and agreements herein set forth, Tenant shall
peaceably and quietly have, hold and enjoy the Premises for the term hereof
without hindrance or molestation from Landlord, subject to the terms and
provisions of this Lease.

19. EVENTS OF DEFAULT  The following events (herein individually referred to as
an "Event of Default") each shall be deemed to be a default in or breach of
Tenant's obligations under this Lease:

    A.   Tenant shall fail to pay an installment of the rent herein reserved
when due, or any other payment or reimbursement to Landlord required herein when
due, and such failure shall continue for a period of five (5) days from the date
such payment was due.

    B.   Tenant shall (i) vacate or abandon all or a substantial portion of the
Premises or (ii) fail to continuously operate its business at the Premises for
the permitted use set forth herein, in either event whether or not Tenant is in
default of the rental payments due under this Lease. 

    C.   Tenant shall fail to discharge any lien placed upon the Premises in
violation of Paragraph 22 hereof within twenty (20) days after any such lien or
encumbrance is filed against the Premises.

    D.   Tenant shall default in the performance of any of its obligations
under any other lease to Tenant from Landlord, or from any person or entity
affiliated with or related to Landlord, and same shall remain uncured after the
lapsing from any applicable cure periods provided for under such other lease.

    E.   Tenant shall fail to comply with any term, provision or covenant of
this Lease (other than those listed above in this paragraph) and shall not cure
such failure within twenty (20) days after written notice thereof from Landlord.

20. REMEDIES.  Upon each occurrence of an Event of Default, Landlord shall have
the option to pursue any one or more of the following remedies without any
notice or demand: 

    (a)  Terminate this Lease;

    (b)  Enter upon and take possession of the Premises without terminating
this Lease;


                                          12

<PAGE>

    (c)  Make such payments and/or take such action and pay and/or perform
whatever Tenant is obligated to pay or perform under the terms of this Lease,
and Tenant agrees that Landlord shall not be liable for any damages resulting to
Tenant from such action; and/or

    (d)  Alter all locks and other security devices at the Premises, with or
without terminating this Lease, and pursue, at Landlord's option, one or more
remedies pursuant to this Lease, and Tenant hereby expressly agrees that
Landlord shall not be required to provide to Tenant the new key to the Premises,
regardless of hour, including Tenant's regular business hours;

and in any such event Tenant shall immediately vacate the Premises, and if
Tenant fails to do so, Landlord, without waiving any other remedy it may have,
may enter upon and take possession of the Premises and expel or remove Tenant
and any other person who may be occupying such Premises or any part thereof,
without being liable for prosecution or any claim of damages therefore.  In the
event of any violation of Section 93.002 of the Texas Property Code by Landlord
or by any agent or employee of Landlord, Tenant hereby expressly waives any and
all rights Tenant may have under Paragraph (g) of such Section 93.002.

    A.   DAMAGES UPON TERMINATION.  If Landlord terminates this Lease at
Landlord's option, Tenant shall be liable for and shall pay to Landlord the sum
of all rental and other payments owed to Landlord hereunder accrued to the date
of such termination, plus, as liquidated damages, an amount equal to (i) the
present value of the total rental and other payments owed hereunder for the
remaining portion of the Lease term, calculated as if such term expired on the
date set forth in Paragraph 1, less (ii) the present value of the then fair
market rental for the Premises for such period, provided that, because of the
difficulty of ascertaining such value and in order to achieve a reasonable
estimate of liquidated damages hereunder, Landlord and Tenant stipulate and
agree, for the purposes hereof, that such fair market rental shall in no event
exceed seventy-five percent (75%) of the rental amount for such period set forth
in Paragraph 2 above.  

    B.   DAMAGES UPON REPOSSESSION.  If Landlord repossesses the Premises
without terminating this Lease, Tenant, at Landlord's option, shall be liable
for and shall pay Landlord on demand all rental and other payments owed to
Landlord hereunder, accrued to the date of such repossession, plus all amounts
required to be paid by Tenant to Landlord until the date of expiration of the
term as stated in Paragraph 1, diminished by all amounts actually received by
Landlord through reletting the Premises during such remaining term (but only  to
the extent of the rent herein reserved).  Actions to collect amounts due by
Tenant to Landlord under this paragraph may be brought from time to time, on one
or more occasions, without the necessity of Landlord's waiting until expiration
of the Lease term.

    C.   COSTS OF RELETTING, REMOVING, REPAIRS AND ENFORCEMENT.  Upon an Event
of Default, in addition to any sum provided to be paid under this Paragraph 20,
Tenant also shall be liable for and shall pay to Landlord (i) brokers' fees and
all other costs and expenses incurred by Landlord in connection with reletting
the whole or any part of the Premises; (ii) the costs of removing, storing or
disposing of Tenant's or any other occupant's property; (iii) the costs of
repairing, altering, remodeling or otherwise putting the Premises into condition
acceptable to a


                                          13

<PAGE>

new tenant or tenants; (iv) any and all costs and expenses incurred by Landlord
in effecting compliance with Tenant's obligation under this Lease; and (v) all
reasonable expenses incurred by Landlord in enforcing or defending Landlord's
rights and/or remedies hereunder, including without limitation all reasonable
attorneys' fees and all court costs incurred in connection with such enforcement
or defense.

    D.   LATE CHARGE.  In the event Tenant fails to make any payment due
hereunder within five (5) days after such payment is due, including without
limitation any rental or escrow payment, in order to help defray the additional
cost to Landlord for processing such late payments and not as interest, Tenant
shall pay to Landlord on demand a late charge in an amount equal to five percent
(5%) of such payment.  The provision for such late charge shall be in addition
to all of Landlord's other rights and remedies hereunder or at law, and shall
not be construed as liquidated damages or as limiting Landlord's remedies in any
manner.
    E.   INTEREST ON PAST DUE AMOUNTS.  If Tenant fails to pay any sum which at
any time becomes due to Landlord under any provision of this Lease as and when
the same becomes due hereunder, and such failure continues for ten (10) days
after the due date for such payment, then Tenant shall pay to Landlord interest
on such overdue amounts from the date due until paid at an annual rate which
equals the lesser of (i) eighteen percent (18%) or (ii) the highest  rate then
permitted by law.   

    F.   NO IMPLIED ACCEPTANCES OR WAIVERS.  Exercise by Landlord of any one or
more remedies hereunder granted or otherwise available shall not be deemed to be
an acceptance by Landlord of Tenant's surrender of the Premises, it being
understood that such surrender can be effected only by the written agreement of
Landlord.  Tenant and Landlord further agree that forbearance by Landlord to
enforce any of its rights under this Lease or at law or in equity shall not be a
waiver of Landlord's right to enforce any one or more of its rights, including
any right previously forborne, in connection with any existing or subsequent
default.  No re-entry or taking possession of the Premises by Landlord shall be
construed as an election on its part to terminate this Lease, unless a written
notice of such intention is given to Tenant, and notwithstanding any such
reletting or re-entry or taking possession of the Premises, Landlord may at any
time thereafter elect to terminate this Lease for a previous default.  Pursuit
of any remedies hereunder shall not preclude the pursuit of any other remedy
herein provided or any other remedies provided by law, nor shall pursuit of any
remedy herein provided constitute a forfeiture or waiver of any rent due to
Landlord hereunder or of any damages occurring to Landlord by reason of the
violation of any of the terms, provisions and covenants contained in this Lease.
Landlord's acceptance of any rent following an Event of Default hereunder shall
not be construed as Landlord's waiver of such Event of Default.  No waiver by
Landlord of any violation or breach of any of the terms, provisions and
covenants of this Lease shall be deemed or construed to constitute a waiver of
any other violation or default.  

    G.   RELETTING OF PREMISES.  In the event of any termination of this Lease
and/or repossession of the Premises for an Event of Default, Landlord shall use
reasonable efforts to relet the Premises and to collect rental after reletting,
with no obligation to accept any lessee that


                                          14

<PAGE>

Landlord deems undesirable or to expend any funds in connection with such
reletting or collection of rents therefrom.  Tenant shall not be entitled to
credit for or reimbursement of any proceeds of such reletting in excess of the
rental owed hereunder for the period of such reletting.  Landlord may relet the
whole or any portion of the Premises, for any period, to any tenant and for any
use or purpose.

    H.   LANDLORD'S DEFAULT.  If Landlord fails to perform any of its
obligations hereunder within thirty (30) days after written notice from Tenant
specifying such failure, Tenant's exclusive remedy shall be an action for
damages.  Unless and until Landlord fails to so cure any default after such
notice, Tenant shall not have any remedy or cause of action by reason thereof. 
All obligations of Landlord hereunder will be construed as covenants, not
conditions; and all such obligations will be binding upon Landlord only during
the period of its possession of the premises and not thereafter.  The term
"Landlord" shall mean only the owner, for the time being, of the Premises and,
in the event of the transfer by such owner of its interest in the Premises, such
owner shall thereupon be released and discharged from all covenants and
obligations of the Landlord thereafter accruing, provided that such covenants
and obligations shall be binding during the Lease term upon each new owner for
the duration of such owner's ownership.  Notwithstanding any other provision of
this Lease, Landlord shall not have any personal liability hereunder.  In the
event of any breach or default by Landlord in any term or provision of this
Lease, Tenant agrees to look solely to the equity or interest then owned by
Landlord in the Premises or the Building; however in no event shall any
deficiency judgment or any money judgment of any kind be sought or obtained
against any Landlord. 

    I.   TENANT'S PERSONAL PROPERTY.  If Landlord repossesses the Premises
pursuant to the authority herein granted, or if Tenant vacates or abandons all
or any part of the Premises, then, in addition to Landlord's rights under
Paragraph 27 hereof, Landlord shall have the right to (i) keep in place and use,
or (ii) remove and store, all of the furniture, fixtures and equipment at the
Premises, including that which is owned by or leased to Tenant, at all times
prior to any foreclosure thereon by Landlord or repossession thereof by any
lessor thereof or third party having a lien thereon.  In addition to the
Landlord's other rights hereunder, Landlord may dispose of the stored property
if Tenant does not claim the property within ten (10) days after the date the
property is stored.  Landlord shall give Tenant at least ten (10) days' prior
written notice of such intended disposition.  Landlord shall also have the right
to relinquish possession of all or any portion of such furniture, fixtures,
equipment and other property to any person ("Claimant") who presents to Landlord
a copy of any instrument represented by Claimant to have been executed by Tenant
(or any predecessor of Tenant) granting Claimant the right under various
circumstances to take possession of such furniture, fixtures, equipment or other
property, without the necessity on the part of Landlord to inquire into the
authenticity or legality of said instrument.  The rights of Landlord herein
stated shall be in addition to any and all other rights that Landlord has or may
hereafter have at law or in equity, and Tenant stipulates and agrees that the
rights granted Landlord under this paragraph are commercially reasonable. 

21. MORTGAGES.  Tenant accepts this Lease subject and subordinate to any
mortgages and/or deeds of trust now or at any time hereafter constituting a lien
or charge upon the Premises


                                          15

<PAGE>

or the improvements situated thereon or the Building, provided, however, that if
the mortgagee, trustee or holder of any such mortgage or deed of trust elects to
have Tenant's interest in this Lease superior to any such instrument, then by
notice to Tenant from such mortgagee, trustee or holder, this Lease shall be
deemed superior to such lien, whether this Lease was executed before or after
said mortgage or deed of trust.  Tenant, at any time hereafter on demand, shall
execute any instruments, releases or other documents that may be required by any
mortgagee, trustee or holder for the purpose of subjecting and subordinating
this Lease to the lien of any such mortgage.  Tenant shall not terminate this
Lease or pursue any other remedy available to Tenant hereunder for any default
on the part of Landlord without first giving written notice by certified or
registered mail, return receipt requested, to any mortgagee, trustee or holder
of any such mortgage or deed of trust, the name and post office address of which
Tenant has received written notice, specifying the default in reasonable detail
and affording such mortgagee, trustee or holder a reasonable opportunity (but in
no event less than thirty (30) days) to make performance, at its election, for
and on behalf of Landlord. 

22. MECHANIC'S LIENS.  Tenant has no authority, express or implied, to create
or place any lien or encumbrance of any kind or nature whatsoever upon, or in
any manner to bind, the interest of Landlord or Tenant in the Premises.  Tenant
will save and hold Landlord harmless from any and all loss, cost or expense,
including without limitation attorneys' fees, based on or arising out of
asserted claims or liens against the leasehold estate or against the right,
title and interest of the Landlord in the Premises or under the terms of this
Lease. 

23. MISCELLANEOUS.

    B.   BINDING EFFECT.  Except as otherwise herein expressly provided, the

upon demand, a corporate resolution, proof of due authorization by partners or
other appropriate documentation evidencing the due authorization of such party

acts of God, labor disputes or other events beyond the control of Landlord.


                                          16

    E.   PAYMENTS CONSTITUTE RENT.  Notwithstanding anything in this Lease to
the contrary, all amounts payable by Tenant to or on behalf of Landlord under
this Lease, whether or not expressly denominated as rent, shall constitute rent.

    F.   ESTOPPEL CERTIFICATES.  Tenant agrees, from time to time, within ten
(10) days after request of Landlord to deliver to Landlord, or Landlord's
designee, an estoppel certificate stating that this Lease is in full force and
effect, the date to which rent has been paid, the unexpired term of this Lease,
any defaults existing under this Lease (or the absence thereof) and such other
factual or legal matters pertaining to this Lease as may be requested by
Landlord.  It is understood and agreed that Tenant's obligation to furnish such
estoppel certificates in a timely fashion is a material inducement or Landlord's
execution of this Lease.

    G.   ENTIRE AGREEMENT.  This lease constitutes the entire understanding and
agreement of Landlord and Tenant with respect to the subject matter of this
Lease, and contains all of the covenants and agreements of Landlord and Tenant
with respect thereto.  Landlord and Tenant each acknowledge that no
representations, inducements, promises or agreements, oral or written, have been
made by Landlord or Tenant, or anyone acting on behalf of Landlord or Tenant,
which are not contained herein, and any prior agreements, promises, negotiations
or representations not expressly set forth in this Lease are of no force or
effect.  EXCEPT AS SPECIFICALLY PROVIDED IN THIS LEASE, TENANT HEREBY WAIVES THE
BENEFIT OF ALL WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT TO THE PREMISES,
INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY THAT THE PREMISES ARE SUITABLE
FOR ANY PARTICULAR PURPOSE.  Landlord's agents and employees do not and will not
have authority to make exceptions, changes or amendments to this Lease, or
factual representations not expressly contained in this Lease.  Under no
circumstances shall Landlord or Tenant be considered an agent of the other. 
This Lease may not be altered, changed or amended except by an instrument in
writing signed by both parties hereto.

    H.   SURVIVAL OF OBLIGATIONS.  All obligations of Tenant hereunder not
fully performed as of the expiration or earlier termination of the term of this
Lease shall survive the expiration or earlier termination of the term hereof,
including without limitation all payment obligations with respect to taxes and
insurance and all obligations concerning the condition and repair of the
Premises.  Upon the expiration or earlier termination of the term hereof, and
prior to Tenant vacating the Premises, Tenant shall pay to Landlord any amount
reasonably estimated by Landlord as necessary to put the Premises in good
condition and repair, reasonable wear and tear excluded, including without
limitation the cost of repairs to and replacements of all heating and air
conditioning systems and equipment therein.  Tenant shall also, prior to
vacating the Premises, pay to Landlord the amount, as estimated by Landlord, of
Tenant's obligation hereunder for real estate taxes and insurance premiums for
the year in which the Lease expires or terminates.  All such amounts shall be
used and held by Landlord for payment of such obligations of Tenant hereunder,
with Tenant being liable for any additional costs therefore upon demand by
Landlord, or with any excess to be returned to Tenant after all such obligations
have been determined and satisfied, as the case may be.  Any Security Deposit
held by Landlord may,


                                          17

<PAGE>

at Landlord's option, be credited against any amounts due from Tenant under this
Paragraph 23H.

    I.   SEVERABILITY OF TERMS.  If any clause or provision of this Lease is
illegal, invalid or unenforceable under present or future laws effective during
the term of this Lease, then, in such event, it is the intention of the parties
hereto that the remainder of this Lease shall not be affected thereby, and it is
also the intention of the parties to this Lease that in lieu of each clause or
provision of this Lease that is illegal, invalid or unenforceable, there be
added, as a part of this Lease, a clause or provision as similar in terms to
such illegal, invalid or unenforceable clause or provision as may be possible
and be legal, valid and enforceable. 

    J.   EFFECTIVE DATE.  All references in this Lease to "the date hereof" or
similar references shall be deemed to refer to the last date, in point of time,
on which all parties hereto have executed this Lease.

    K.   BROKERS' COMMISSION.  Tenant represents and warrants that it has dealt
with and will deal with no broker, agent or other person in connection with this
transaction or future related transactions and that no broker, agent or other
person brought about this transaction, and Tenant agrees to indemnify and hold
Landlord harmless from and against any claims by any broker, agent or other
person claiming a commission or other form of compensation by virtue of having
dealt with Tenant with regard to this leasing transaction.

    L.   AMBIGUITY.  Landlord and Tenant hereby agree and acknowledge that this
Lease has been fully reviewed and negotiated by both Landlord and Tenant, and
that Landlord and Tenant have each had the opportunity to have this Lease
reviewed by their respective legal counsel, and, accordingly, in the event of
any ambiguity herein, Tenant does hereby waive the rule of construction that
such ambiguity shall be resolved against the party who prepared this Lease.

    M.   JOINT SEVERAL LIABILITY.  If there be more than one Tenant, the
obligations hereunder imposed upon Tenant shall be joint and several.  If there
be a guarantor of Tenant's obligations hereunder, the obligations hereunder
imposed upon Tenant shall be joint and several obligations of Tenant and such
guarantor, and Landlord need not first proceed against Tenant before proceeding
against such guarantor, nor shall any such guarantor be released from its
guaranty for any reason whatsoever, including, without limitation, in case of
any amendments hereto, waivers hereof or failure to give such guarantor any
notices hereunder.

    N.   THIRD PARTY RIGHTS.  Nothing herein expressed or implied is intended,
or shall be construed, to confer upon or give to any person or entity, other
than the parties hereto, any right or remedy under or by reason of this Lease.

    O.   EXHIBITS AND ATTACHMENTS.  All exhibits, attachments, riders and
addenda referred to in this Lease, and the exhibits listed herein below and
attached hereto, are incorporated into this Lease and made a part hereof for all
intents and purposes as if fully set out herein.  All


                                          18

<PAGE>

capitalized terms used in such documents shall, unless otherwise defined
therein, have the same meanings as are set forth herein.

    P.   APPLICABLE LAW.  This Lease has been executed in the State of Texas
and shall be governed in all respects by the laws of the State of Texas.  It is
the intent of Landlord and Tenant to conform strictly to all applicable State
and federal usury laws.  All agreements between Landlord and Tenant, whether now
existing or hereafter arising and whether written or oral, are hereby expressly
limited so that in no contingency or event whatsoever shall the amount
contracted for, charged or received by Landlord for the use, forbearance or
retention of money hereunder or otherwise exceed the maximum amount which
Landlord is legally entitled to contract for, charge or collect under the
applicable state or federal law.  If, from any circumstance whatsoever,
fulfillment of any provision hereof at the time performance of such provision
shall be due shall involve transcending the limit of validity prescribed by law,
then the obligation to be fulfilled shall be automatically reduced to the limit
of such validity, and if from any such circumstance Landlord shall ever receive
as interest or otherwise an amount in excess of the maximum that can be legally
collected, then such amount which would be excessive interest shall be applied
to the reduction of rent hereunder, can be legally collected, then such amount
which would be excessive interest shall be applied to the reduction of rent
hereunder, and if such amount which would be excessive interest exceeds such
rent, then such additional amount shall be refunded to Tenant.

24. NOTICES.  Each provision of this instrument or of any applicable
governmental laws, ordinances, regulations and other requirements with reference

place.  In the event a prospective tenant desires to lease this space from
Landlord, Landlord shall notify Tenant thereof in the manner provided herein for
notice, whereupon Tenant shall have five (5) days after receipt of such notice
in which to elect to exercise Tenant's right of first refusal.  In the event
Tenant fails to give Landlord written notice of Tenant's election to lease the
adjacent space within said five (5) day period, Tenant shall have no further
right, title or interest in the adjacent space and this right of first refusal
shall terminate and be of no further force and effect.  If, on the other hand,
Tenant exercises its right of first refusal in the manner provided above, the
lease of the adjacent property shall be consummated at a fair market rental
rate.

RENEWAL OPTION

extension, renewal, modification, forbearance or delay or other act or omission
of the Landlord, or its failure to proceed promptly or otherwise or by reason of
any action taken or omitted by the Landlord, whether or not such action or
failure to act varies or increases the risk of or, affects the rights or
remedies of, the Guarantors, and the Guarantors hereby expressly waive and
surrender any defense to the Guarantors' liability hereunder based upon any of
the foregoing acts, omissions, things, agreements or waivers of any of them, it

been enforceable against the Tenant.

preceding calendar year and, within

                             MASTER LEASE AGREEMENT

                          LESSOR:  COPELCO CAPITAL INC.


                         LESSEE:    1ST TECH CORPORATION

                          TERMS AND CONDITIONS OF LEASE

I.     LEASE OF EQUIPMENT.

Lessor hereby leases to Lessee, and Lessee hereby leases from Lessor, the
equipment described in one or more equipment schedules (the "Equipment
Schedule") substantially in the form of Exhibit A attached hereto, that may
hereafter be executed by Lessor and Lessee (the equipment, together with all
replacement parts, repairs, additions, substitutions and accessories shall be
referred to as the "Equipment") on the terms and conditions contained in this
Lease ("Lease") and in any Equipment Schedule.  This Lease and each of the
terms, covenants, conditions, provisions and agreements herein contained will be
incorporated into each Equipment Schedule in full to the same extent as if each
of the terms, covenants, conditions, provisions and agreements had been repeated
and set forth in full therein, and this Master Lease Agreement shall control and
be effective as to all such Schedules except to the extent that the Master Lease
Agreement may be inconsistent with the terms and provisions of such Equipment
Schedule, in which event the terms and provisions of such Equipment Schedule
shall prevail.  Each Equipment Schedule shall constitute a separate lease and a
distinct and independent obligation of the Lessee.  The parties intend this
Lease to be a "Finance Lease" under Article 2A of the Uniform Commercial Code.

II.    ORDER AND DELIVERY OF EQUIPMENT; LESSOR'S RIGHT TO TERMINATE.

Lessee hereby requests Lessor to order the Equipment from the Vendor named on
the Equipment Schedule and to arrange for delivery of the Equipment to Lessee at
Lessee's expense, and to lease the Equipment to Lessee.  If the Equipment is not
delivered to and accepted by Lessee in form satisfactory to Lessor, within
ninety (90) days from the date Lessor orders the Equipment, Lessor may terminate
the applicable Equipment Schedule and its obligations thereunder.  Lessee waives
any requirement of Lessor to furnish Lessee a copy of Lessor's purchase order
for the Equipment.

III.   ACCEPTANCE.

Lessee shall, as Lessor's agent, immediately inspect the Equipment after it is
delivered and installed.  Lessee agrees that on the date the Equipment is
available for first use (the "Acceptance Date"), it shall execute and deliver to
Lessor a Delivery and Acceptance Certificate substantially in the form of
Exhibit B attached.  Notwithstanding the foregoing, unless Lessee shall notify
Lessor in writing otherwise within five (5) days after the Acceptance Date,
Lessee shall be deemed to have irrevocably accepted the Equipment.  This Lease
and all Equipment Schedules are non-cancelable, and Lessee agrees to pay the
total rent for the term, which shall be the total amount of all rental

<PAGE>

payments stated in any Equipment Schedule (the "Rent" or "Rental Payment"), plus
any other sums provided for herein.

IV.    TERM AND RENT.

(A)    The initial term ("Initial Term") of any Equipment Schedule to which this
Lease relates shall commence on the Acceptance Date and shall be of such
duration as is prescribed in such Equipment Schedule plus the Interim Term (as
hereinafter defined).  Advance Rent and any Security Deposit as provided in any
Equipment Schedule shall be payable upon the execution of the applicable
Equipment Schedule and shall not be refundable if the Initial Term for any
reason does not commence or if this Lease or the applicable Equipment Schedule
is duly terminated by Lessor.  Rental Payments shall commence (the "Commencement
Date") on the first day of the month following the Acceptance Date unless the
Acceptance Date is the first day of the applicable period, in which case the
Commencement Date shall be the first day of the applicable period.  Interim Rent
shall be payable upon demand for the period between the Acceptance Date and the
first day of the month following the Acceptance Date ("Interim Term") at a daily
rate equal to the periodic rental provided in any Equipment Schedule divided by
the number of days in the period.  Subsequent rental payments shall be due
periodically in advance on the first day of each successive period thereafter
until all Rent and other sums chargeable to the Lessee hereunder are paid in
full.  Lessee's obligation to pay Rent and Lessee's other monetary obligations
hereunder are absolute and unconditional and are not subject to any abatement,
set-off, defense or counterclaim for any reason whatsoever.  Any Security
Deposit shall secure all obligations of Lessee hereunder and may be applied at
Lessor's discretion to any past due obligation of Lessee and to the extent not
applied shall be returned to Lessee, without interest, at the expiration of the
applicable Equipment Schedule.  All payments of Rent shall be made to Lessor at
the address Lessor shall designate in writing.
(B)    Whenever any payment is not made by Lessee within five (5) days of when
due hereunder, Lessee agrees to pay to Lessor, as additional rent, interest on
all monies due Lessor from and after the date same is due at the rate of one and
one-quarter (1-1/4%) percent per month until paid, but as to each of the
foregoing in no event more than the maximum rate permitted by law.
(C)    As used herein, "Actual Cost" means the cost to Lessor of purchasing and
delivering the Equipment to Lessee, including taxes, transportation and other
charges.  The amount of each Rental Payment and the Security Deposit set forth
in the Equipment Schedule are based on the total cost set forth in Lessor's
purchase order for the Equipment ("Estimated Cost"), which is an estimate, and
shall be adjusted proportionately if the actual cost of the Equipment is greater
than said estimate.  Lessee hereby authorizes Lessor to adjust the amounts set
forth in the Equipment Schedule when the Actual Cost is known and to add to the
amount of each Rental Payment any sales, use or leasing tax that may be imposed
on or measured by the Rental Payments.  Lessor will inform Lessee of the
adjustments necessary to reflect Actual Cost.  If the Actual Cost of the
Equipment on any Equipment Schedule exceeds the Estimated Cost by more than ten
(10%) percent thereof (exclusive of taxes), Lessor shall, if it desires to, add
to the Estimated Cost an amount in excess of 10% of Estimated Cost, so notify
Lessee in writing.  In such instance, within fifteen (15) days thereafter,
Lessee at its option may terminate the relevant Equipment Schedule by giving
notice to Lessor of its intention to do so, effective the day of such notice,
subject however to the provisions of Section IV(A) hereof.

V.     NO WARRANTIES BY LESSOR, DISCLAIMER OF IMPLIED WARRANTIES AND WAIVER OF
       DEFENSES.

LESSOR IS NOT THE MANUFACTURER OR SUPPLIER OF OR A DEALER IN THE EQUIPMENT, AND
MAKES NO WARRANTY, EXPRESSED OR IMPLIED, TO ANYONE, AS TO THE SUITABILITY,
DURABILITY, DESIGN, CONDITION, CAPACITY, PERFORMANCE OR ANY OTHER ASPECT OF THE
EQUIPMENT OR ITS MATERIAL OR WORKMANSHIP INCLUDING THE WARRANTY OF
MERCHANTABILITY AND FITNESS FOR USE OR PURPOSE.  AS TO LESSOR AND ITS ASSIGNS,
LESSEE LEASES THE EQUIPMENT "AS IS."  LESSEE REPRESENTS THAT IT HAS SELECTED THE
EQUIPMENT AND THE SUPPLIER AND ACKNOWLEDGES THAT LESSOR HAS NOT RECOMMENDED THE
SUPPLIER.  LESSOR SHALL HAVE NO OBLIGATION TO INSTALL, MAINTAIN, ERECT, TEST,
ADJUST, OR SERVICE THE EQUIPMENT, ALL OF WHICH LESSEE SHALL PERFORM, OR CAUSE
THE SAME TO BE PERFORMED BY QUALIFIED THIRD PARTIES.  LESSOR AND LESSOR'S
ASSIGNEE SHALL NOT BE LIABLE TO LESSEE OR OTHERS FOR ANY LOSS, DAMAGE OR EXPENSE
OF ANY KIND OR NATURE CAUSED DIRECTLY OR INDIRECTLY BY ANY EQUIPMENT HOWEVER
ARISING, OR THE USE OR MAINTENANCE THEREOF OR THE FAILURE OF OPERATION THEREOF,
OR THE REPAIRS, SERVICE OR ADJUSTMENT THERETO.  NO REPRESENTATION OR WARRANTY AS
TO THE EQUIPMENT OR ANY OTHER MATTER BY THE SUPPLIER OR OTHERS SHALL BE BINDING
ON LESSOR NOR SHALL THE BREACH OF SUCH RELIEVE LESSEE OF, OR IN ANY WAY AFFECT,
ANY OF LESSEE'S OBLIGATIONS TO LESSOR HEREIN.  IF THE EQUIPMENT IS
UNSATISFACTORY FOR ANY REASON, LESSEE SHALL MAKE CLAIM ON ACCOUNT THEREOF SOLELY
AGAINST SUPPLIER, AND ANY OF SUPPLIER'S VENDORS, AND SHALL NEVERTHELESS PAY
LESSOR ALL RENT AND OTHER SUMS PAYABLE UNDER THIS LEASE.  LESSOR HEREBY ASSIGNS
TO LESSEE, SOLELY FOR THE PURPOSE OF PROSECUTING SUCH A CLAIM, ALL (IF ANY) OF
THE RIGHTS WHICH LESSOR MAY HAVE AGAINST SUPPLIER AND SUPPLIER'S VENDORS FOR
BREACH OF WARRANTY OR OTHER REPRESENTATIONS RESPECTING THE EQUPIMENT.
REGARDLESS OF CAUSE, LESSEE WILL NOT ASSERT ANY CLAIM WHATSOEVER AGAINST LESSOR
FOR LOSS OF ANTICIPATORY PROFITS OR ANY OTHER INDIRECT, SPECIAL OR CONSEQUENTIAL
DAMAGES, NOR SHALL LESSOR BE RESPONSIBLE FOR ANY DAMAGES OR COSTS WHICH MAY BE
ASSESSED AGAINST LESSEE IN ANY ACTION FOR INFRINGEMENT OF ANY UNITED STATES
LETTERS PATENT.  LESSOR MAKES NO WARRANTY AS TO THE TREATMENT OF THIS LEASE FOR
TAX OR ACCOUNTING PURPOSES.  NOTHWITHSTANDING ANY FEES WHICH MAY BE PAID BY
LESSOR TO SUPPLIER OR ANY AGENT OF SUPPLIER, LESSEE UNDERSTANDS AND AGREES THAT
NEITHER SUPPLIER NOR ANY AGENT OF SUPPLIER IS AN AGENT OF LESSOR OR IS
AUTHORIZED TO WAIVE OR ALTER ANY TERM OR CONDITION OF THIS LEASE.

VI.    TITLE; PERSONAL PROPERTY.

The equipment is, and shall at all times be owned by Lessor and Lessee shall
have no interest in the Equipment except that of a lessee.  The Lessee shall
have no right to purchase or otherwise acquire title to or ownership of any of
the Equipment.  If Lessor supplies Lessee with labels indicating that the
Equipment is owned by Lessor, Lessee shall affix such labels to and keep them in
a prominent place on the Equipment.  Lessee hereby authorizes Lessor to insert
in any Equipment Schedule the serial numbers and other identification data of
Equipment when determined by Lessor.  To protect Lessor's rights in the
Equipment in the event this Lease is determined to be a security agreement,
Lessee hereby grants to Lessor a security interest in the Equipment, and all
proceeds, products, rents or profits from the sale, casualty loss or other
disposition thereof.  Lessee hereby authorizes Lessor, at Lessee's expense, to
cause this Lease, or any statement or other instrument in respect of this Lease
showing the interest of Lessor in the Equipment, 

                                            3

<PAGE>

including Uniform Commercial Code financing statements, to be filed or 
recorded and re-filed and re-recorded, and grants Lessor the right to execute 
Lessee's name thereto.  Lessee agrees to execute, deliver and file any 
statement or instrument requested by Lessor for such purpose, and if 
certificates of title are issued or outstanding with respect to any of the 
Equipment, Lessee will cause the interest of Lessor to be properly noted 
thereon, and agrees to pay or reimburse Lessor for any reasonable searches, 
filings, recordings, stamp fees or taxes related to the filing or recording 
of any such instrument or statement, plus Lessor's handling charges. Lessee 
shall, at its expense, protect and defend Lessor's title against all persons 
claiming limitation liens, attachments, levies and executions, and shall give 
Lessor immediate written notice thereof and shall indemnify Lessor from any 
loss waivers and such further instruments and assurances as Lessor deems 
necessary or advisable for the confirmation or perfection of Lessor's rights 
hereunder.  The Equipment is, and shall at all times be and remain, personal 
property notwithstanding that the Equipment or any part thereof may now be or 
hereafter become, in any manner, affixed or attached to real property or any 
improvements thereon.

VII.   MAINTENANCE, USE AND LOCATION.

Lessee shall, at its own cost and expense, maintain the Equipment in good
operating condition and repair and protect the Equipment from deterioration
other than normal wear and tear; shall use the Equipment in the regular course
of its business, within its normal operating capacity, without abuse; shall
comply with all laws, ordinances, regulations, requirements and rules with
respect to the use, maintenance and operation of the Equipment; shall not make
any modification, alteration or addition to the Equipment without the prior
written consent of Lessor, which shall not be unreasonably withheld, except for
engineering changes recommended by and made by the manufacturer; shall install
on the Equipment all engineering changes offered by the manufacturer without
charge which enhance the safety of the Equipment; shall not so affix the
Equipment to realty as to change its nature to real property or a fixture; and
shall keep the Equipment at the location shown herein, and shall not remove the
Equipment without prior written consent of Lessor.  Lessee will grant access to
the Equipment to Lessor and Lessor's designee during normal working hours for
inspection, repair, preventative maintenance, installation of engineering
changes and for any other reasonable purpose.  Lessee shall, during the term of
this Lease, at its own expense, enter into and maintain in force a contract with
the manufacturer or other acceptable maintenance company covering the
maintenance of the Equipment and furnish a copy thereof to Lessor upon request.
If Lessor incurs any costs or expenses to bring the Equipment up to good working
order and appearance, Lessee shall immediately reimburse Lessor for all such
costs or expenses.

VIII.  RETURN OF EQUIPMENT; END OF LEASE OPTION.

After the end of the Initial Term and each renewal term thereafter, this Lease
shall be automatically renewed and shall continue until such time as the Lessee
shall give the Lessor written notice of termination, not less than one hundred
twenty (120) days and not more than one hundred eighty (180) days prior to the
end of the then current term.  Unless Lessee purchase the Equipment or the term
of an Equipment Schedule is renewed, within ten (10) days of the expiration or
earlier termination of the then current term, the


                                        4
<PAGE>

Lessee shall, at its expense, de-install, inspect, test and pack the Equipment
and return the Equipment (including all cable, wiring, connectors, accessories
and attachments thereto), freight and insurance prepaid, to such location as
designated by Lessor in writing, in good repair, condition and working order
ordinary wear and tear resulting from proper use thereof only excepted.
Further, the Equipment shall conform to any additional specifications set forth
in the applicable Equipment Schedule.  Lessee shall have the Equipment certified
by the manufacturer as acceptable for the manufacturer's standard maintenance
contract and such certification shall be presented to Lessor at least fourteen
(14) days prior to re-delivery to Lessor.  If Lessee fails to return the
Equipment as provided herein, Lessee shall pay Lessor a sum equal to six (6)
months rent as liquidated damages to compensate Lessor for the economic loss
suffered by Lessor as a result of its inability to realize the residual value of
the Equipment when anticipated.  In addition, for the use of the Equipment,
Lessee agrees to pay Lessor periodic Rental equal to one hundred ten (110%)
percent of the average annual Rental Payment (adjusted, if necessary, to the
period indicated on the applicable Equipment Schedule) provided herein.  Nothing
contained herein is intended to relieve Lessee of its obligations to return the
Equipment to Lessor as provided herein or restrict Lessor's right to recover the
Equipment in the event of the failure of Lessee to so return the Equipment at
the expiration or termination of the applicable Equipment Schedule.

IX.    RISK OF LOSS.

Lessee shall bear all risks of loss or damage to the Equipment ("Loss") from any
cause whatsoever, from the date of the shipment of the Equipment to Lessee until
its return to Lessor.  Lessee shall promptly notify Lessor of any Loss and no
Loss shall relieve the Lessee of the obligation to pay Rent or of any other
obligation under this Lease and any Equipment Schedule.  In the event of a Loss,
Lessee, at the option of Lessor, shall either (a) repair the Equipment so as to
place it in as good condition as prior to the Loss, (b) replace the Equipment
with substantially identical Equipment in good condition and working order with
documentation creating clear title thereto in Lessor; or (c) pay to Lessor upon
demand the sum of the following amounts:  (i) the aggregate Rent and other sums
then due and owing under the Equipment Schedule to which the Equipment is
subject plus (ii) the applicable stipulated loss value attached to the Equipment
Schedule and made part thereof (the "Stipulated Loss Values") opposite the Rent
payment number preceding the date of the Loss, or, if no Stipulated Loss Values
are attached to the Equipment Schedule, then the present value of all unpaid
Rent and other sums due during the unexpired term of the Equipment Schedule
discounted at four (4%) percent per annum simple interest or the lowest rate
permitted by law plus Lessor's anticipated value of the Equipment at the end of
the Initial Term or applicable renewal term.  Upon Lessor's receipt of
replacement Equipment or payment as provided in (b) or (c) hereof, Lessee and/or
Lessee's insurer shall be entitled to Lessor's interest in said item for salvage
purposes, in its then condition and location, without warranty, express or
implied.

X.     INSURANCE.

Lessee shall keep the Equipment insured against all risks of loss or damage from
every cause whatsoever for not less than the full replacement value thereof or
the amount stated in Section IX(c) herein, whichever is greater,


                                        5
<PAGE>

and shall carry public liability and property damage insurance covering the
Equipment and its use in amounts customary for such Equipment.  All such
insurance shall be in form and amount and with companies acceptable to Lessor
and name Lessor and its assignee as loss payee, as their interests may appear,
with respect to property damage coverage and as additional insured, with respect
to public liability coverage.  Lessee shall pay the premiums therefor and
deliver said policies, or duplicates thereof or certificates of coverage
therefor to Lessor, with long form Lender's Loss Payable endorsement upon the
policy or policies or by independent instrument, that provides Lessor a right to
thirty (30) days' written notice before the policy can be altered or canceled
and the right without obligation to payment of premium.  Should Lessee fail to
provide such coverage, Lessor may obtain such coverage for its benefit or for
the benefit of Lessee and charge Lessee therefor.  Lessee hereby appoints Lessor
as Lessee's attorney-in-fact to make claim for, receive payment of, and execute
and endorse all documents, checks, or drafts for loss or damage under any said
insurance policies and to apply the proceeds in furtherance of the exercise of
Lessor's options as provided herein.

XI.    TAXES AND CHARGES.

This Lease is intended to be a net lease, and all payments hereunder are
intended to be net to Lessor to the extent permitted by applicable law.  Lessee
shall pay directly (or, at Lessor's option, reimburse Lessor for) all license
fees, assessments and other government charges, and all sales, use, excise,
franchise, personal property and any other similar tax or taxes (herein
collectively called "Charges") now or hereafter imposed, levied or assessed by
any state, federal or local government or agency upon any of the Equipment or
upon the leasing, purchase, ownership, use, possession, financing or operation
thereof, or upon the receipt of rental payments therefor, even if Lessee's
status provides for its exemption from the Charges (excluding income taxes on
Rental Payments, except any such tax on Rental Payments which is substitution
for, or relieves Lessee from, the payment of taxes which Lessee would otherwise
be obligated to pay or reimburse Lessor as herein provided) before the same
shall become in default or subject to the payment of any penalty or interest.
Lessee shall supply Lessor with receipts or other evidence of payment of all
Charges as may reasonably be requested by Lessor.  Lessee shall further comply
with all state and local laws requiring the filing of ad valorem or other tax
returns relating to any Charges.  Lessee shall notify the Lessor of the
imposition of, or, to Lessee's knowledge, the proposed imposition of, any
Charges by supplying to Lessor (within in five (5) days after receipt thereof by
Lessee) a copy of the invoice or other documents respecting such Charges.
Unless otherwise directed by Lessor in writing, Lessor shall pay all personal
property taxes with respect to the Equipment and Lessee shall reimburse Lessor
therefor upon demand.

XII.   LEASE IRREVOCABILITY AND OTHER COVENANTS AND REPRESENTATIONS OF LESSEE.

Lessee agrees that this Lease and each Equipment Schedule are irrevocable for
the full term hereof and thereof and Lessee's obligations under this Lease and
each Equipment Schedule are absolute and shall continue without abatement and
regardless of any disability of Lessee to use the Equipment or any part thereof
because of any reason including, but not limited to war, act of God,
governmental regulations, strike, loss, damage, destruction, obsolescence,
failure of or delay in delivery, failure of the Equipment to operate properly,

termination by operation of law, or any other cause.  Lessee represents that:
it is duly organized, validly existing and in good standing under the laws of
the jurisdiction in which the activities of Lessee require such qualification;
this Lease has been and each Equipment Schedule will be duly authorized by all
necessary action on its part, is a valid, binding and legally enforceable
obligation of Lessee in accordance with its terms and is not in any respect
inconsistent with or in violation of Lessee's Certificate or Articles of
Incorporation or by-laws or any law, regulation, order or agreement binding upon
Lessee; the Equipment shall be used by Lessee solely for business purposes; and
that all financial and other information submitted to Lessor was and will be
true and correct.

XIII.  FINANCIAL STATEMENTS.

Lessee agrees to deliver to Lessor annual financial statements and such
quarterly financial statements, as Lessor requests.

XIV.   DEFAULT AND REMEDIES.

(A)    The occurrence of any one or more of the following shall be deemed to be
an "Event of Default": (a)  Lessee fails to pay any Rent or any other amount
hereunder when due; or (b) Lessee is in default under any other agreement
between Lessee and Lessor or upon an event of default under any other agreement
entered into by guarantors, the vendor of the Equipment, principals of Lessee or
others, which agreement(s) was or were executed to induce Lessor to enter into
this Lease or the applicable Equipment Schedule; or (c)  Lessee fails to perform
or observe any of the terms, covenants or conditions contained in this Lease,
any Equipment Schedule or other lease or other agreement  between Lessor and
Lessee, other than as provided above, and Lessee fails to cure any such breach
within ten (10) days after notice thereof or (d) any representation of Lessee
contained in this Lease or any other agreement between Lessor and Lessee, or in
any credit or other information submitted to Lessor in connection with this
transaction is untrue or incorrect; or (e) Lessee sells substantially all of its
assets out of the ordinary course of business, merges or consolidates with any
other person, or sustains a change in the ownership of more than 20% of its
equity; or (f) Lessee becomes insolvent or makes an assignment for the benefit
of creditors; or (g) a receiver, trustee, conservator or liquidator of Lessee or
of all or a substantial part of its assets is appointed with our without the
application or consent of Lessee; or (h) a petition is filed by or against
Lessee under the Bankruptcy Code or any amendment thereto, or under any other
insolvency law or laws, providing for the relief to debtors.

(B)    Upon an Event of Default, the Lessor may, to the extent permitted by
applicable law, exercise any one or more of the following remedies:

          (i)  Terminate this Lease with respect to all or any part of the
       Equipment;

          (ii)  Recover from Lessee all Rent and other amounts then due as they
       shall thereafter become due hereunder and under the Equipment Schedules;


                                        7
<PAGE>


       (iii)  Take possession of any or all items of Equipment, wherever the
       same may be located, without demand or notice, without any court order or
       other process of law and without liability to Lessee for any damages
       occasioned by such taking of possession, and any such taking of
       possession shall not constitute a termination of this Lease;

       (iv)  Declare the entire unpaid balance of Rent and other amounts for the
       unexpired term of each Equipment Schedule immediately due and payable and
       recover from Lessee, with respect to any and all items of Equipment (with
       or without repossessing same), the Stipulated Loss Value attached to each
       Equipment Schedule opposite the Rent Payment number preceding the date of
       such Event of Default or, if no Stipulated Loss Values are attached to
       the applicable Equipment Schedule, then the present value of all unpaid
       Rent and other sums due during the unexpired term of that Equipment
       Schedule discounted at four (4%) percent per annum simple interest (or
       the lowest discount rate permitted by law), plus Lessor's anticipated
       value of the Equipment at the end of the Initial Term or any applicable
       renewal term of the Equipment Schedule.

       (v)  Upon repossession or surrender of any Equipment, Lessor shall sell,
       lease or otherwise dispose of such Equipment in a commercially reasonable
       manner, with or without notice and on public or private bid, and apply
       the net proceeds thereof (after deducting all expenses, including
       attorneys' fees incurred in connection therewith), to the sum of (iv)
       above;

       (vi)  Declare any other Equipment Schedules and leases between Lessor and
       Lessee in default and exercise any of the remedies provided for herein;
       and

       (vii)  Pursue any other remedy available at law or in equity, including
       but not limited to seeking damages or specific performance and/or
       obtaining an injunction.

   (C)    Lessee shall be liable and shall pay to Lessor all expenses incurred
by Lessor in connection with the enforcement of any of Lessor's remedies,
including all expenses of repossessing, storing, shipping, repairing, and
selling the Equipment, and Lessor's reasonable attorney's fees.  Lessor and
Lessee acknowledge the difficulty in establishing a value for the unexpired
lease term and owing to such difficulty agree that the provisions of this
Section XIV represent an agreed measure of damages and are not to be deemed a
forfeiture or penalty.

(D)    All remedies of Lessor hereunder are cumulative, are in addition to any
other remedies provided for by law, and may, to the extent permitted by law, be
exercised concurrently or separately.  The exercise of any one remedy shall not
be deemed to be an election of such remedy or to preclude the exercise of any
other remedy.  No failure on the part of Lessor to exercise and no delay in
exercising any right or remedy shall operate as a waiver thereof or modify the
terms of this Lease or any Equipment Schedule.  A waiver of default shall not be
a waiver of any other or subsequent default.  If this Lease is determined to be
subject to any laws limiting the amount chargeable or


                                        8
<PAGE>

collectible by Lessor then Lessor's recovery shall in no event exceed the
maximum amounts permitted by law.







                                        9
<PAGE>

XV.    INDEMNITY.

Lessee shall indemnify and hold Lessor, its agents, employees, successors and
assigns, harmless from and against any and all claims, actions, suits,
proceedings, costs, expenses, damages and liabilities, including attorney's
fees, arising out of, connected with, or resulting from the Equipment, any
Equipment Schedule or this Lease, including without limitation, the manufacture,
selection, delivery, possession, use, lease, operation, removal or return of the
Equipment.

XVI.   REPRODUCTION OF DOCUMENTS.

This Lease, any Equipment Schedule and all related documents, including (a)
amendments, addendums, consents, waivers and modifications which may be executed
contemporaneously or subsequently herewith, (b) documents received by the Lessor
from the Lessee, and (c)  financial statements, certificates and other
information previously or subsequently furnished to the Lessor, may be
reproduced by the Lessor by any photographic, photostatic, microfilm, micro-
card, miniature photographic, compact disk reproduction or other similar process
and the Lessor may destroy any original document so reproduced.  The Lessee
agrees and stipulates that any such reproduction shall, to the extent permitted
by applicable law, be admissible in evidence as the original itself in any
judicial or administrative proceeding (whether or not the original is in
existence and whether or not the reproduction was made by the Lessor in the
regular course of business) and that any enlargement, facsimile or further
reproduction of the reproduction shall likewise be admissible in evidence.

XVII.  ASSIGNMENT; WAIVER OF DEFENSES; QUIET ENJOYMENT.

LESSEE SHALL NOT ASSIGN, TRANSFER, PLEDGE, HYPOTHECATE, OR OTHERWISE DISPOSE OF,
ENCUMBER OR PERMIT A LIEN UPON OR AGAINST ANY INTEREST IN THIS LEASE, ANY
EQUIPMENT SCHEDULE OR THE EQUIPMENT OR PERMIT THE EQUIPMENT TO BE USED BY ANYONE
OTHER THAN LESSEE OR LESSEE'S EMPLOYEES WITHOUT LESSOR'S PRIOR WRITTEN CONSENT.
Lessor may, without consent or notice to Lessee, assign or transfer this Lease
or any Equipment Schedule or grant a security interest in any Equipment, any
Rental Payments, or any other sums due to become due hereunder, and in such
event Lessor's assignee, transferee or grantee shall have all the rights,
powers, privileges, and remedies of Lessor hereunder.  Lessor agrees that no
assignee of Lessor shall be bound to perform any duty, covenant, condition or
warranty attributable to Lessor, and Lessee further agrees not to raise any
claim or defense arising out of this Lease or otherwise which it may have
against Lessor as a defense, counterclaim, or offset to any action by an
assignee or secured party hereunder.  Upon Lessor's request, Lessee will execute
a consent and acknowledgment of Lessor's assignment to its assignee.  Nothing
contained herein is intended to relieve Lessor of any of its obligations.
Provided Lessee is not in default hereunder, Lessee shall quietly use and enjoy
the Equipment, subject to the terms hereof.

XVIII.  PERFORMANCE BY LESSOR OF LESSEE'S OBLIGATIONS.

In the event Lessee fails to comply with any provisions of this Lease, Lessor
shall have the right, but shall not be obligated, to effect such compliance on
behalf of Lessee upon ten (10) days prior written notice to Lessee.  In such
event, all monies expended by, and all expenses of Lessor in effecting such


                                       10
<PAGE>

compliance shall be deemed to be additional rent, and shall be paid by Lessee to
Lessor at the time of the next payment, together with interest at the rate of
one and one-quarter (1-1/4%) percent per month but in no event more than the
maximum permitted by law.

XIX.   GOVERNING LAW; JURISDICTION AND VENUE; WAIVER OF TRIAL BY JURY AND RIGHTS
       AND REMEDIES UNDER THE UNIFORM COMMERCIAL CODE.

This Lease shall be governed by the laws of the State of New Jersey, provided,
however, in the event this Lease or any provision hereof is not enforceable
under the laws of the State of New Jersey, then the laws of the state where
Equipment is located shall govern.  LESSEE CONSENTS TO THE PERSONAL JURISDICTION
OF THE FEDERAL AND STATE COURTS OF THE STATE OF NEW JERSEY WITH RESPECT TO ANY
ACTION ARISING OUT OF THIS LEASE, ANY EQUIPMENT SCHEDULE OR THE EQUIPMENT,
PROVIDED, HOWEVER, LESSOR MAY IN ITS SOLE DISCRETION, ENFORCE THIS LEASE AND ANY
EQUIPMENT SCHEDULE IN ANY COURT HAVING LAWFUL JURISDICTION THEREOF.  THIS MEANS
ANY LEGAL ACTION ARISING OUT OF THIS LEASE MAY BE FILED IN NEW JERSEY, AND
LESSEE MAY BE REQUIRED TO DEFEND AND LITIGATE ANY SUCH ACTION IN NEW JERSEY.
LESSEE AGREES THAT SERVICE OF PROCESS IN ANY SUIT MAY BE MADE BY CERTIFIED MAIL,
RETURN RECEIPT REQUESTED, ADDRESSED TO LESSEE AT THE ADDRESS SET FORTH HEREIN.
TO THE EXTENT PERMITTED BY LAW, LESSEE WAIVES TRIAL BY JURY IN ANY ACTION BY OR
AGAINST LESSOR HEREUNDER AND WAIVES ANY AND ALL RIGHTS AND REMEDIES GRANTED TO
LESSEE BY ARTICLE 2A OF THE UNIFORM COMMERCIAL CODE AND ANY RIGHTS NOW OR
HEREAFTER GRANTED BY STATUTE OR OTHERWISE THAT MAY LIMIT OR MODIFY LESSOR'S
RIGHTS AS DESCRIBED IN THIS LEASE OR THE EQUIPMENT SCHEDULES.

XX.    GENERAL.

This Lease shall inure to the benefit of and is binding upon the heirs,
legatees, personal representatives, successors and permitted assigns of the
parties hereto.  Time is of the essence of this Lease.  This Lease and any
Equipment Schedule shall be effective when accepted by Lessor.  This Lease and
the Equipment Schedules contain the entire agreement between Lessor and Lessee
with respect to the subject matter hereof, and all negotiations and
understandings have been merged herein.  No modification of this Lease shall be
effective unless in writing and executed by both Lessor and Lessee.  All
covenants and obligations of Lessee to be performed pursuant to this Lease,
including all payments to be made by Lessee hereunder, shall survive the
expiration or the earlier termination of this Lease.  If more than one Lessee is
named in this Lease, the liability of each shall be joint and several.  In the
event any provision of this Lease shall be unenforceable, then such provision
shall be deemed deleted, however, all other provisions hereof shall remain in
full force and effect.  Service of all notices under this Lease shall be
sufficient if given personally, mailed to the party intended at its address set
forth herein, or at such other addresses said party may provide in writing from
time to time by certified mail, or overnight mail service, or sent via facsimile
transmission.  Any such notice mailed to said address shall be deemed effective
three (3) days after it is deposited in the United States mail, duly addressed
and with postage prepaid; all notices sent by other means shall be deemed
effective when received.

</TABLE>



                          TERMS AND CONDITIONS OF LEASE
1. LEASE OF EQUIPMENT.
A. Lessor hereby leases to Lessee, and Lessee hereby leases from Lessor, the
equipment described above and on any schedule made a part hereof (the
"Schedule") (the equipment with all replacement parts, repairs, additions,
substitutions and accessories called the "Equipment") on the terms and
conditions on the face and reverse side hereof and on any Schedule hereto
(collectively the "Lease" or "Leases" unless the context indicates otherwise).
Lessee authorizes Lessor to insert in the Lease or any Schedule, the
Commencement Date, the serial numbers and other identification data of the
Equipment and other omitted factual matters when determined by Lessor.


                                       13
<PAGE>

B.  Acceptance by Lessor shall occur only as set forth in this Section 1 and
shall continue in force with respect to all items of Equipment for the Initial
Term specified in each Schedule.  Lessee agrees promptly to date, execute and
deliver to Lessor, upon delivery to Lessee of the first item of Equipment listed
on a Schedule a confirmation of delivery on Lessor's Delivery and Acceptance
Receipt form ("Receipt").  If Lessee does not, for any reason, date, execute and
deliver to Lessor the Receipt, within ten days after delivery of such item of
Equipment, Lessee hereby irrevocably authorizes the Lessor as its attorney-in-
fact to execute the Receipt on Lessee's behalf and to insert the date that the
Equipment was delivered to Lessee.

2.  ORDER AND DELIVERY OF EQUIPMENT; LESSOR'S RIGHT TO TERMINATE. Lessee hereby
requests Lessor to order the Equipment from the Supplier named above and to
arrange for delivery of the Equipment to Lessee at Lessee's expense, and lease
the Equipment to Lessee.  If the Equipment is not delivered to and accepted by
Lessee in form satisfactory to Lessor, within ninety (90)days from the date
Lessor orders the Equipment, Lessor may terminate this Lease and its obligations
hereunder to Lessee.  Lessee waives any requirement of Lessor to furnish Lessee
a copy of Lessor's purchase order for the Equipment.

3.  TERM AND RENT.
A.  The initial term ("Initial Term") of any Schedule to which this Lease
relates shall commence on the day the first item of Equipment listed on such
Schedule is delivered to Lessee or Lessee's representative (the "Commencement
Date") and shall be of such duration as is prescribed in such Schedule.  Advance
Rent and any Security Deposit as provided in any Schedule shall be payable upon
the execution of this Lease or the applicable Schedule and shall not be
refundable if the lease term for any reason does not commence or if this Lease
is duly terminated by Lessor.  Interim rent shall be payable for the period
between the Commencement Date and the first day of the month following the
Commencement Date at a daily rate equal to the periodic rental provided in any
Schedule divided by the number of days in the period and subsequent payments
shall be due periodically in advance on the first day of each successive period
thereafter until all rent and other sums chargeable to Lessee hereunder are paid
in full.  Lessee's obligation to pay rent and Lessee's other monetary
obligations hereunder are absolute and unconditional and are not subject to any
abatements, set-off, defense or counterclaim for any reason whatsoever. Any
Security Deposit shall secure all obligations of Lessee hereunder and may be
applied at Lessor's discretion to any past due obligation of Lessee and to the
extent not applied shall be returned to Lessee, without interest, at the
expiration of this Lease or the applicable Schedule.  All payment of rent shall
be made to Lessor at the address set forth herein or such other address as
Lessor shall designate in writing.
B. Whenever any payment is not made by Lessee when due hereunder, Lessee agrees
to pay  to Lessor, not later than one month thereafter interest on all monies
due Lessor from and after the date same is due at the rate of one and one-half
(1-1/2%) percent per month until paid, but as to each of the foregoing in no
event more than the maximum rate permitted by law.
C.  As used herein, "Actual Cost" means the cost to Lessor of purchasing and
delivering the Equipment to Lessee, including taxes, transportation and other
charges.  The amount of each Rental Payment and the Security Deposit set forth
in the Schedule are based on the total cost set forth in Lessor's purchase order
for the Equipment ("Equipment Cost"), which is an estimate, and shall be
adjusted proportionately if the actual cost of the Equipment is greater than


                                       14
<PAGE>

said estimate.  Lessee hereby authorizes Lessor to adjust upward the amounts set
forth in the Schedule when the actual cost is known and to add to the amount of
each Rental Payment any sales, use or leasing tax that may be imposed on or
measured by the Rental Payments.  Lessor will inform Lessee of the adjustments
necessary to reflect Actual Cost.  If the Actual Cost of the Equipment on any
Schedule exceeds the Estimated Cost by more than ten (10%) percent thereof
(exclusive of taxes), Lessor shall, if it desires to add to the Estimated Cost
an amount in excess of 10% of Estimated Cost, so notify Lessee in writing.
Within fifteen days (15) days thereafter, Lessee at its option may terminate the
relevant Schedule by giving notice to Lessor of its intention to do so,
effective the day of such notice, subject however to the provisions of Section
3.A hereof.
If, at any time prior to acceptance of the Equipment leased hereunder, Lessor
makes a general pricing increase with respect to new leases (including increases
reflecting increases in financing cost or operating expenses) and desires that
such increase be reflected in the Rental Payments to be charged to Lessee under
the Schedule relating to such Equipment, then Lessor shall promptly notify
Lessee of such increase ("Increase Notification").  If such increase is in
excess of ten (10%) percent of the amount of the Rental Payment, Lessee at its
option may terminate the relevant Schedule; provided, however, the Lessor must
be notified, within fifteen (15) days after the date of Increase Notification,
of Lessee's intentions to do so, effective the day of such notice to Lessor.  If
any increase under this Section 3.D is not in excess of ten (10%) of the Rental
Payment, or if Lessor is not notified of Lessee's intentions to terminate the
relevant Schedule within the fifteen (15) day period set forth herein, the
relevant Schedule shall be automatically adjusted to the new higher Rental
Payment.

4.  NO WARRANTIES BY LESSOR, DISCLAIMER OF IMPLIED WARRANTIES AND WAIVER OF 
DEFENSES.  LESSOR IS NOT THE MANUFACTURER OR SUPPLIER OF OR A DEALER IN THE 
EQUIPMENT, AND MAKES NO WARRANTY, EXPRESSED OR IMPLIED, TO ANYONE, AS TO THE 
SUITABILITY, DURABILITY, DESIGN, CONDITION, CAPACITY, PERFORMANCE OR ANY 
OTHER ASPECT OF THE EQUIPMENT OR ITS MATERIAL OR WORKMANSHIP.  LESSOR FURTHER 
DISCLAIMS ANY IMPLIED WARRANTIES OF ANY KIND WITH RESPECT TO THE EQUIPMENT 
INCLUDING THE WARRANTY OF MERCHANTABILITY AND FITNESS FOR USE OR PURPOSE. AS 
TO LESSOR AND ITS ASSIGNS, LESSEE LEASES THE EQUIPMENT "AS 1S."  LESSEE 
REPRESENTS THAT IT HAS SELECTED THE EQUIPMENT AND THE SUPPLIER AND 
ACKNOWLEDGES THAT LESSOR HAS NOT RECOMMENDED THE SUPPLIER. LESSOR SHALL HAVE 
NO OBLIGATION TO INSTALL, MAINTAIN, ERECT, TEST, ADJUST, OR SERVICE THE 
EQUIPMENT, ALL OF WHICH LESSEE SHALL PERFORM, OR CAUSE THE SAME TO BE 
PERFORMED BY QUALIFIED THIRD PARTIES. LESSOR AND LESSOR'S ASSIGNEE SHALL NOT 
BE LIABLE TO LESSEE OR OTHERS FOR ANY LOSS, DAMAGE OR EXPENSE OF ANY KIND OR 
NATURE CAUSED DIRECTLY OR INDIRECTLY BY ANY EQUIPMENT HOWEVER ARISING, OR THE 
USE OR MAINTENANCE THEREOF OR THE FAILURE OF OPERATION THEREOF, OR THE 
REPAIRS, SERVICE OR ADJUSTMENT THERETO. NO REPRESENTATION OR WARRANTY AS TO 
THE EQUIPMENT OR ANY OTHER MATTER BY THE SUPPLIER OR OTHERS SHALL BE BINDING 
ON THE LESSOR NOR SHALL THE BREACH OF SUCH RELIEVE LESSEE OF, OR IN ANY WAY 
AFFECT, ANY OF LESSEE'S OBLIGATIONS TO LESSOR HEREIN. IF THE EQUIPMENT IS 
UNSATISFACTORY FOR ANY REASON LESSEE SHALL MAKE CLAIM ON ACCOUNT THEREOF 
SOLELY AGAINST SUPPLIER, AND ANY OF SUPPLIER'S VENDORS, AND SHALL 
NEVERTHELESS PAY LESSOR ALL RENT AND OTHER SUMS PAYABLE UNDER THIS LEASE. 
LESSOR HEREBY ASSIGNS TO LESSEE, SOLELY FOR THE PURPOSE OF PROSECUTING SUCH A 
CLAIM, ALL (IF ANY) OF THE RIGHTS WHICH LESSOR MAY HAVE AGAINST SUPPLIER AND 
SUPPLIER'S 

                                       15

<PAGE>

VENDORS FOR BREACH OF WARRANTY OR OTHER REPRESENTATIONS RESPECTING THE 
EQUIPMENT.

REGARDLESS OF CAUSE, LESSEE WILL NOT ASSERT ANY CLAIM WHATSOEVER AGAINST LESSOR
FOR LOSS OF ANTICIPATORY PROFITS OR ANY OTHER INDIRECT, SPECIAL OR CONSEQUENTIAL
DAMAGES, NOR SHALL LESSOR BE RESPONSIBLE FOR ANY DAMAGES OR COSTS WHICH MAY BE
ASSESSED AGAINST LESSEE IN ANY ACTION FOR INFRINGEMENT OF ANY UNITED STATES
LETTERS PATENT. LESSOR MAKES NO WARRANTY AS TO THE TREATMENT OF THIS LEASE FOR
TAX OR ACCOUNTING PURPOSES.

NOTWITHSTANDING ANY FEES WHICH MAY BE PAID BY LESSOR TO SUPPLIER OR ANY AGENT OF
SUPPLIER, LESSEE UNDERSTANDS AND AGREES THAT NEITHER SUPPLIER NOR ANY AGENT OF
SUPPLIER IS AN AGENT OF LESSOR OR IS AUTHORIZED TO WAIVE OR ALTER ANY TERM OR
CONDITION OF THIS LEASE.

5.  JURISDICTION AND VENUE.  LESSEE CONSENTS TO THE PERSONAL JURISDICTION OF THE
FEDERAL AND STATE COURTS OF THE STATE OF NEW JERSEY WITH RESPECT TO ANY ACTION
ARISING OUT OF THIS LEASE OR THE EQUIPMENT PROVIDED HOWEVER LESSOR MAY IN ITS
SOLE DISCRETION ENFORCE THIS LEASE IN ANY COURT HAVING LAWFUL JURISDICTION
THEREOF. THIS MEANS ANY LEGAL ACTION ARISING OUT OF THIS LEASE MAY BE FILED IN
NEW JERSEY, AND LESSEE MAY BE REQUIRED TO DEFEND AND LITIGATE ANY SUCH ACTION IN
NEW JERSEY.  LESSEE AGREES THAT SERVICE OF PROCESS IN ANY SUIT MAY BE MADE BY
CERTIFIED MAIL.  RETURN RECEIPT REQUESTED ADDRESSED TO THE LESSEE AT THE ADDRESS
SET FORTH HEREIN. TO THE EXTENT PERMITTED BY LAW, LESSEE WAIVES TRIAL BY JURY IN
ANY ACTION BY OR AGAINST LESSOR HEREUNDER.

6. TITLE; PERSONAL PROPERTY.  The Equipment is, and shall at all times be owned
by Lessor and Lessee shall have no interest in the Equipment except that of
Lessee and Lessee shall have no right to purchase or otherwise acquire title to
or ownership of any of the Equipment.  If Lessor supplies Lessee with labels
indicating that the Equipment is owned by Lessor, Lessee shall affix such labels
to and keep them in a prominent place on the Equipment.  Lessee hereby
authorizes Lessor to insert in this Lease the serial numbers, and other
identification data of Equipment when determined by Lessor.  To protect Lessor's
rights in the Equipment in the event this Lease is determined to be a security
agreement, Lessee hereby grants to Lessor a security interest in the Equipment
and all proceeds, rents or profits therefrom.  Lessee authorizes Lessors, at
Lessee's expense, to cause this Lease or any statement or other instrument in
respect of this Lease showing the interest of Lessor in the Equipment, including
Uniform Commercial Code financing statements, to be filed or  recorded and
refiled and re-recorded, and grants Lessor the right to execute Lessee's name
thereto.  Lesseee agrees to execute, deliver and file any statement or
instrument requested by Lessor for such purpose, and if certificates of title
are issued or outstanding with respect to any of the Equipment, Lessee will
cause the interest of Lessor to be properly noted thereon, and agrees to pay or
reimburse Lessor for any searches, filings, recordings, stamp fees or taxes
related to the filing or recording of any such instrument or statement, plus
Lessor's handling charges.  Lessee shall, at its expense, protect and defend
Lessor's title against all persons claiming against or through Lessee, at all
times keeping the Equipment free from any legal process or encumbrance
whatsoever including but not limited to liens, attachments, levies and
executions, and shall give Lessor immediate written notice thereof and shall
indemnify Lessor from any loss caused thereby, Lessee shall, upon Lessor's
request execute or obtain from third parties and deliver


                                       16
<PAGE>

to Lessor such estoppel certificates, landlord's waivers and such further
instruments and assurances as Lessor deems necessary or advisable for the
confirmation or perfection of Lessor's rights hereunder.  The Equipment is, and
shall at all times be and remain, personal property  notwithstanding that the
Equipment or any part thereof may now be or hereafter become, in any manner,
affixed or attached to real property or any improvements  thereon.

7.  MAINTENANCE, USE AND LOCATION.  Lessee shall, at it own cost and expense,
maintain the Equipment in good operating condition and repair and protect the
Equipment from deterioration other than normal wear and tear; shall use the
Equipment in the regular course of its business, within its normal operating
capacity, without abuse; shall comply with all laws, ordinances, regulations,
requirements and rules with respect to the use, maintenance and operation of the
Equipment; shall not make any modification, alteration or addition to the
Equipment without the prior written consent of Lessor, which shall not be
unreasonably withheld, except for engineering changes recommended by and made by
the manufacturer; shall install on the Equipment all engineering changes offered
by the manufacturer without charge which enhance the safety of the Equipment;
shall not so affix the Equipment to realty as to change its nature to real
property or a fixture; and shall deep the Equipment at the location shown
herein, and shall not remove the Equipment without prior consent of Lessor.
Lessee will grant access to the Equipment to Lessor, Lessor's designee, and the
manufacturer during normal working hours for inspection, repair, preventative
maintenance, installation of engineering changes and for any other reasonable
purpose.  Lessee shall during the term of this Lease, at its own expense, enter
into and maintain in force a contract with the manufacturer or other acceptable
maintenance company covering the maintenance of the Equipment and furnish a copy
thereof to Lessor upon request.  If Lessor incurs any cost or expenses to bring
the Equipment up to good working order and appearance, Lessee shall immediately
reimburse Lessor for all such costs or expenses.

8.  REDELIVERY; RENTAL TERM. After the Initial Term, and after each renewal term
thereafter, this Lease shall be automatically renewed for a term of six months,
unless Lessee shall give written notice of termination at least one hundred
eighty (180) days before the expiration of the then current term.  Within (10)
days of Expiration or earlier termination of this lease, Lessee shall return the
Equipment and all cable, wirng, connectors, accessories and attachments thereto,
freight and insurance prepaid, to Lessor in good repair, condition and working
order, ordinary wear and tear resulting from proper use thereof only excepted.
Lessee shall have the Equipment certified as acceptable for the manufacturer's
standard maintenance contract and such certification shall be presented to
Lessor at least fourteen (14) days prior to redelivery to Lessor.  Lessor shall
have the right, by notice to Lessee, and at Lessee's cost, to make all
arrangements for the discontinuance, disassembly, packing and transportation of
each item of Equipment and to designate a redelivery location. If Lessee fail to
return the Equipment as provided herein, Lessee shall pay Lessor a sum equal to
one (1) year's rent as liquidated damages to compensate Lessor for the economic
loss suffered by Lessor as a result of its inability to realize the residual
value of the Equipment when anticipated.  In addition, for the use of the
Equipment, Lessee agrees to pay Lessor monthly rent equal to 110% of the average
annual Rental Payment (adjusted, if necessary, to a monthly period) provided
herein.  Nothing contained herein is intended to relieve Lessee of its
obligation to


                                       17
<PAGE>

return the Equipment to Lessor as provided herein or restrict Lessor's right to
recover the Equipment in the event of the failure of Lessee to so return the
Equipment at the expiration or termination of this Lease.  If requested by
Lessor, Lessee shall store the Equipment at Lessee's premises for a period of up
to ninety (90) days at no cost to Lessor.

9.  RISK OF LOSS.  Lessee shall bear all risks of loss or damage to Equipment
from any cause from the date of the shipment of the Equipment to Lessee until
its return to Lessor.  The occurrence of any such loss or damage shall not
relieve Lessee of any obligation hereunder.  Lessee shall notify Lessor of any
damage to or destruction of the Equipment.  In the event of loss or damage,
Lessee, at Lessor's sole option shall: (a) repair the damaged Equipment; or (b)
replace lost or unrepairable Equipment in good condition and working order with
documentation creating clear title thereto in Lessor; or (c) pay to Lessor the
present value of the unpaid balance of the aggregate rent reserved under this
Lease plus Lessor's anticipated residual value of the Equipment at the scheduled
expiration of this Lease discounted at six (6%) percent per annum to the date of
loss.  Upon Lessor's receipt of replacement Equipment or payment as provided in
(b) or (c) hereof, Lessee and/or Lessee's insurer shall be entitled to Lessor's
interest in said item for salvage purposes, in its then condition and location,
without warranty, express or implied.

10. INSURANCE.  Lessee shall keep the Equipment insured against all risks of
loss or damage from every cause whatsoever for not less than the full
replacement value thereof, and shall carry public liability and property damage
insurance covering the Equipment and its use in amounts customary for such
Equipment.  All such insurance shall be in form and amount and with companies
acceptable to Lessor and name Lessor and its assignee as Loss Payee, as their
interest may appear with respect to property damage coverage and as Additional
Insured with respect to public liability coverage.  Lessee shall pay the
premiums therefor and deliver said polices, or duplicates thereof or
certificates of coverage therefor to Lessor with long form Lender's Loss Payable
endorsement upon the policy or policies or by independent instrument, that
provides Lessor a right to thirty (30) days' written notice before the policy
can be altered or canceled and the right without obligation to payment of
premium.  Should Lessee fail to provide such insurance coverage, Lessor may
obtain such coverage for its benefit or for the benefit of Lessee and charge
Lessee therefor.  Lessee hereby appoint Lessor as Lessee's attorney-in-fact to
make claim for, receive payment of and execute and endorse all documents,
checks, or drafts for loss or damage under any said insurance polices and to
apply the proceeds in furtherance of the exercise of Lessor's options as
provided herein.

11.  TAXES AND CHARGES. This Lease is intended to be a net lease, and all
payments hereunder are intended to be net to Lessor to the extent permitted by
applicable law.  Lessee shall pay directly (or, at Lessor's option, reimburse
Lessor for) all license fees, assessments and other government charges, and all
sales, use, excise, franchise, personal property and any other similar tax or
taxes (herein collectively called "Charges") now or hereafter imposed, levied or
assessed by any state, federal or local government or agency upon any of the
Equipment or upon the leasing, purchase, ownership, use, possession, financing
or operation thereof, or upon the receipt of rental payments therefor, even if
Lessee's status provides for its exemption from the Charges (excluding income
and gross receipt taxes on the rental payments,


                                       18
<PAGE>

except any such tax on rental payments which is substitution for, or relieves
Lessor from, the payment of taxes which Lessee would otherwise be obligated to
pay or reimburse Lessor as herein provided) before the same shall become in
default or subject to the payment of any penalty or interest.  Lessee shall
supply Lessor with receipts or other evidence of payment of all Charges as may
reasonably be requested by Lessor. Lessee shall further comply with all state
and local laws requiring the filing of ad valorem or other tax returns relating
to any Charges.  Lessee shall notify the Lessor of the imposition of, or, to
Lessee's knowledge, the proposed imposition of, any charges by supplying to
Lessor (within five (5) days after receipt thereof by Lessee) a copy of the
invoice or other documents respecting such Charges.  Unless otherwise directed
by Lessor in writing, Lessor shall pay all personal property taxes with respect
to the Equipment and Lessee shall reimburse Lessor therefor upon demand.

12.  LEASE IRREVOCABILITY AND OTHER COVENANTS AND REPRESENTATIONS OF LESSEE.
Lessee agrees that this Lease is irrevocable for the full term hereof and the
Lessee's obligations under this Lease are absolute and shall continue with out
abatement and regardless of any disability of Lessee to use Equipment or any
part thereof because of any reason including, but not limited to war, act of
God, governmental regulations strike, loss, damage, destruction, obsolescence,
failure or delay in delivery, failure of the Equipment to operate properly,
termination by operation of law, or any other cause.  Lessee agrees to deliver
to Lessor annual financial statements and such interim statements, as Lessor
requests.  Lessee represents that this Lease has been duly authorized by all
necessary action on its part, is a valid, binding and legally enforceable
obligation of Lessee in accordance with its terms and is not in any respect
inconsistent with Lessee's Charter or By-Laws, regulation, order or agreement
binding upon Lessee; and the Equipment shall be used by Lessee solely for
business purposes and that all financial and other information submitted to
Lessor was and will be true and correct.

13.  INDEMNITY.  Lessee shall indemnify and hold Lessor harmless from and
against any and all claims, actions, suits, proceedings, costs, expenses,
damages and liabilities, including attorney's fees, arising out of, in
connection with, or resulting from the Equipment or this Lease, including
without limitation, the manufacture, selection, delivery, possession, use,
lease, operation, removal or return of the Equipment.

14.  DEFAULT AND REMEDIES.
A.  If any one of the following events shall occur: (a) Lessee fails to pay any
rent or any other payment hereunder when due; or (b) Lessee fails to pay, when
due, any indebtedness to Lessor arising independently of this Lease, including
but not limited to, any other leases between Lessor and Lessee, and such default
shall continue for five (5) days; or (c) Lessee fails to perform any of the
terms, covenants or conditions of this Lease or any other lease between Lessor
and Lessee, other than as provided above, after ten (10) days written notice; or
(d) any representation of Lessee contained in this Lease or any other related
agreement, or in any credit or other information submitted to Lessor in
connection with this transaction is untrue or incorrect; or (e) Lessee sells
substantially all of its assets out of the ordinary course of business, merges
or consolidates with any other person, or, if a corporation, sustains a change
in the ownership of more than 20% in the aggregate of its issued and outstanding
stock of any class; or (f) Lessee becomes insolvent or


                                       19
<PAGE>

makes an assignment for the benefit of creditors; or (g) a receiver, trustee,
conservator or liquidator of Lessee or of all or a substantial part of its
assets is appointed with or without the application or consent of Lessee; or (h)
a petition is filed by or against Lessee under the Bankruptcy Code or any
amendment thereto, or under any other insolvency law or laws, providing for the
relief to debtors, Lessor may, to the extent permitted by applicable law
exercise any one or more of the following remedies:
     (i)   Terminate this Lease with respect to all or any part of Equipment.
     (ii)  Recover from Lessee all rent and other amounts then due and as they
           shall thereafter become due hereunder;
     (iii) Take possession of any or all items of Equipment, wherever the same
           may be located, and any such taking of possession shall not
           constitute a termination of this Lease;
     (iv)  Declare the entire unpaid balance of rent and other amounts for the
           unexpired term of this Lease immediately due and payable and recover
           from Lessee, with respect to any and all items of Equipment and with
           or without repossessing the Equipment the sum of:

           1.   The unpaid balance of all rent and other amounts due for the
                balance of the term of this Lease, discounted at six (6%)
                percent per annum simple interest;
           2.   The "reversionary value" of the Equipment as of the end of the
                Initial Term, which Lessee for this purpose agrees shall be ten
                (10%) percent of the total cost of the Equipment to Lessor,
                discounted at six (6%) percent per annum simple interest;
                provided, however, that upon repossession or surrender of
                Equipment, Lessor shall sell, lease or otherwise dispose of
                Equipment in a commercially reasonable manner, with or without
                notice and on public or private bid, and apply the net proceeds
                thereof (after deducting all expenses, including attorneys' fees
                incurred in connection therewith), to the sum of (1) and (2)
                above;
     (v)   Declare any other leases between Lessor and Lessee in default and
           exercise with respect to such leases any of the remedies provided for
           herein;
     (vi)  Pursue any other remedy available at law or in equity, including but
           not limited to seeking damages or specific performance and/or
           obtaining an injunction.

B.  Lessee shall be liable and shall pay to Lessor all expenses incurred by
Lessor in connection with the enforcement of any of the Lessor's remedies,
including all expenses of repossessing, storing, shipping, repairing, and
selling the Equipment, and Lessor's reasonable attorney's fees.  Lessor and
Lessee acknowledge the difficulty in establishing a value for the Equipment
lease term and owing to such difficulty agree that the provisions of this
paragraph 14 represent an agreed measure of damages and are not to be deemed a
forfeiture or penalty.

C. All remedies of Lessor hereunder are cumulative, are in addition to any other
remedies provided for by law, and may, to the extent permitted by law, be
exercised concurrently or separately.  The exercise of any one remedy shall not
be deemed to be an election of such remedy or to preclude the exercise of any
other remedy.  No failure on the part of the Lessor to exercise and no


                                       20
<PAGE>

delay in exercising any right or remedy shall operate as a waiver thereof or
modify the terms of this Lease.  A waiver of default shall not be a waiver of
any other or subsequent default.  If this Lease is determined to be subject to
any laws limiting the amount chargeable or collectible by Lessor's recovery
shall in no event exceed the maximum amounts permitted by law.

D. Upon default by Lessee in any of the terms and conditions of this Lease, to
the extent and if permitted by applicable law, Lessee authorizes and empowers
the Prothonotary or Clerk of Court or any attorney of any court of record to
appear for Lessee and enter a judgment by confession or in a amicable action in
any court of competent jurisdiction under this provision in favor of Lessor or
its assignee, with or without averment or declaration filed, for possession of
the Equipment and/or for such sum or sums as may be payable by reason of the
terms of this Lease, including any sums as may be past due at the time of
repossession on acceleration, and such additional sums as may be incurred by
reasonable attorney's fees.  The authority to confess judgment either for
possession of the Equipment or any money due hereunder shall not be exhausted by
one exercise, but judgments may be confessed from time to time, as often as may
be necessary.

15. ASSIGNMENT; WAIVER OF DEFENSES; QUIET ENJOYMENT.  LESSEE SHALL NOT ASSIGN,
TRANSFER, PLEDGE, HYPOTHECATE, OR OTHERWISE DISPOSE OF THIS LEASE OR ANY
INTERESTS HEREUNDER NOR SUBLET OR LEND EQUIPMENT OR PERMIT IT TO BE USED BY
ANYONE OTHER THAN LESSEE OR LESSEE'S EMPLOYEES WITHOUT LESSOR'S PRIOR WRITTEN
CONSENT.  Lessor may, without consent, assign or transfer this Lease or grant a
security interest in any Equipment, any rentals, or any other sums due or to
become due hereunder, and in such event Lessor's assignee, transferee or grantee
shall have all rights, power, privileges, and remedies of Lessor hereunder.
Lessee agrees that, following its receipt of notice of any assignment by Lessor
of this Lease or the Rental Payments payable hereunder, it will pay the Rental
Payments due hereunder directly to the assignee (or to whomever the assignee
shall designate).  Lessee agrees that no assignee of Lessor shall be bound to
perform any duty, covenant, condition or warranty attributable to Lessor, and
Lessee further agrees not to raise any claim or defense arising out of this
Lease or otherwise which it may have against Lessor as a defense, counterclaim,
or offset to any action by an assignee or secured party hereunder.  Upon
Lessor's request, Lessee will acknowledge to any assignee receipt of Lessor's
notice of assignment.  Nothing contained herein is intended to relieve Lessor of
any of its obligations.  Provided Lessee is not in default hereunder, Lessee
shall quietly use and enjoy the Equipment, subject to the terms hereof.

16. PERFORMANCE BY LESSOR OF LESSEE'S OBLIGATIONS.  In the event Lessee fails to
comply with any provisions of this Lease, Lessor shall have the right, but shall
not be obligated, to effect such compliance on behalf of Lessee upon ten (10)
days prior written notice to Lessee.  In such event, all monies expended by, and
all expenses of Lessor in effecting such compliance shall be deemed to be
additional rent, and shall be paid by Lessee at the time of the next rent
payment, together with interest at the rate of one and one-half (1-1/2%) percent
per month but in no event more than that maximum permitted by law.

17.  GOVERNING LAW; JURISDICTION AND VENUE; WAIVER OF TRIAL BY JURY AND RIGHTS
AND REMEDIES UNDER THE UNIFORM COMMERCIAL CODE.  The Lease shall be governed by
the laws of the State of New Jersey, provided however, in the event this



                                       21
<PAGE>

Lease or any provision hereof is not enforceable under the laws of the State of
New Jersey then the laws of the state where the Equipment is located shall
govern.  To the extent permitted by law, Lessee waives trial by jury in any
action by or against Lessor hereunder.  Lessee hereby waives any and all rights
and remedies granted Lessee by Section 2A-508 through 2A-522 of the Uniform
Commercial Code including, by way of example only and not as a limitation, the
right to repudiate this Lease and reject the Equipment; the right to cancel this
Lease; to revoke acceptance of the Equipment; granting a security interest in
the Equipment in Lessee's possession and control for any reason; recover damages
thereunder for any breach of warranty or for any other reason deduct all or any
part of the claimed damages resulting from Lessor's default, if any, under this
Lease; accept partial delivery of the Equipment; "cover" by making any purchase
or lease of or contract to purchase or lease equipment in substitution for those
due from Lessor; recover any general, special, incidental or consequential
damages, for any reason whatsoever; and specific performance, replevin, detinue,
sequestration, claim and delivery and the like for the Equipment identified to
this lease.

18.  GENERAL.  This Lease shall insure to the benefit of and is binding upon the
heirs, legatees, personal representatives, successors and assigns of the parties
hereto.  Time is of the essence of this Lease.  This Lease and any Schedule
shall be effective when accepted in writing by Lessor at its principal offices
in New Jersey by its President or any Vice President.  This Lease and any
Schedule contains the entire agreement between Lessor and Lessee with respect to
the subject matter hereof, and all negotiations and understandings have been
merged herein.  No modification of this Lease shall be effective unless in
writing and executed by any executive officer of Lessor.  All covenants and
obligations of Lessee to be performed pursuant to this Lease, including all
payments to be made by Lessee hereunder, shall survive the expiration or earlier
termination of this Lease.  If more than one Lessee is named in this Lease, the
liability of each shall be joint and several.  In the event any provision of
this Lease shall be unenforceable, then such provision shall be deemed deleted,
however, all other provisions hereof shall remain in full force and effect.
Service of all notices under this Lease shall be sufficient if given personally,
mailed to the party intended at its address set forth herein, or at such other
addresses said party may provide in writing from time to time by certified mail,
or overnight mail service, or sent via facsimile transmission.  Any such notice
mailed to said address shall be effective when deposited in the United States
mail, duly addressed and with postage prepaid.

19.  MASTER LEASE.  This Lease may be used as a Master Lease between Lessor and
Lessee, and shall govern any Schedules now or hereafter executed by Lessor and
Lessee, which refer to this Lease.

IN WITNESS WHEREOF, Lessor and Lessee have dated this Lease the 17th day of
December, 1993.
