BUSINESS STRATEGY

The Company aspires to become a leading provider of manufactured equipment,
engineered systems and services used in the niche industrial markets in which it
operates and to expand its markets through acquisition of complementary product
and service lines as an industry consolidator in the $30 billion industrial
weighing and material handling equipment industry. SI Technologies has
experienced significant growth since 1990 through a combination of internal
growth and strategic acquisitions.

Internal Growth

The Company expects to continue generating organic growth through internal
product development, entrance into new markets and geographic expansion. In the
past several years, internal investment has been focused on expansion of the
weighing system product line and installation of a company-wide marketing
information system. In 1998, the Company expects to shift its product
development focus to certain opportunities in the load handling and moving
product line.

Acquisition Strategy

SI Technologies pursues a strategy of acquiring leading providers of
complementary manufactured products and services in highly fragmented industrial
equipment markets, with a view to further consolidating those markets. SI
Technologies believes it is one of the few domestic acquirers and

                                       2

<PAGE>   3
consolidators of businesses in those markets. In general, the Company pursues
the acquisition of businesses that meet the following criteria.

        *       Well-managed, typically privately held, domestic companies
                serving niche industrial markets.

        *       Products utilizing technology compatible with SI core
                technologies.

        *       Significant installed product base and successful operating
                history.

        *       Complementary products and services that offer cross-selling
                opportunities.

        *       Potential for international business expansion.

        *       Predictable cash flow and earnings potential.

SI believes its consolidation strategy will allow it to achieve greater
efficiencies in acquired companies through elimination of redundant cost,
merging MIS systems, consolidating company service providers and economies of
scale. Past the early stages of assimilating acquired companies, SI expects to
capitalize on revenue synergies developed through cross-selling, joint market
development, and sharing and integration of technology across product lines.

The Company intends to finance acquisitions in the near term primarily with
debt, relieved subsequently by capital raised through the sale of equity. As the
momentum of the consolidation plan increases, the Company expects to utilize
equity on an increasing basis as currency in acquisition and merger
transactions.

Since 1990, SI Technologies has completed five acquisitions. The most recent of
these was the purchase of AeroGo, Inc. in July of 1997. AeroGo is a leading
manufacturer of load handling and moving systems.

PRODUCTS AND SERVICES

Weighing Systems

SI designs and manufactures dynamic and stationary electronic weighing systems
for use in a wide array of industrial applications. As a result of the
uniqueness of the Company's weighing system products, SI is one of few
manufacturers in the industry who design and manufacture all three of the
primary components of an electronic scale. These components are the load
handling structure, force measurement devices and instrumentation. Many
manufacturers of conventional scale systems manufacture only load handling
structures, outsourcing to standard industry suppliers their force measurement
device and instrumentation requirements. The Company utilizes its expertise and
manufacturing know-how in each of these critical components to competitive
advantage and believes their broad expertise can be exploited through their
consolidation strategy.

Dynamic or mobile weighing systems commonly known as on-board scales are
installed on transportation vehicles and material handling equipment to inform
operators, and record for operations management; gross vehicle, axle group,
payload, and incremental pick-up and delivery weights as the vehicle is loaded
or unloaded. SI systems are available in modular kits for use on all major
original equipment manufacturer (OEM) trucks, trailers, forklifts and loaders.
Products are marketed under the AirScale, RouteMan, SmartPin, Trojan, TruxScale,
and Tuffer trade names to the aggregate, agriculture, construction, forestry,
freight transportation, mining, and waste management industries. These
industries constitute the primary markets for on-board weighing systems as they
often have loads that vary in weight, are difficult to estimate and fleets that
load and unload in locations that are not in close proximity to conventional
in-ground truck scales. The systems are utilized to increase productivity and
reduce operating expense in material handling, loading and transporting
operations. Depending on application, specific economic benefit is derived from
reduced overweight vehicle fines and delays; reduced time loading, checkweighing
and adjusting loads to maximum legal limits; reduced mileage and driving time to
checkweighing locations such as commercial in-ground truck scales; immediate
measurement and recording of pick-up and delivery weights; reduced equipment
abuse, maintenance downtime and expense; and higher capital equipment capacity
utilization.

On-board system components include a microprocessor-based electronic meter
(instrumentation) mounted in the cab of the vehicle and force measurement
devices (FMDs) installed in the suspension or load lifting power system of the
vehicle or material handling equipment. The meter supplies power to the FMDs,
provides all operator interface and controls, processes FMD electronic signals
to determine weights, and displays and records in memory weights and other
inputs from the system and/or the operator. Force measurement devices employing
electronic strain gage technology measure loads. The electrical resistance of
FMDs changes proportionally to the load applied; thus the return signal to the
meter varies by load.

The company's stationary weighing system product line consists of scales
designed for numerous industrial weighing applications. Key products marketed
under the trade names Lodec, Road Guardian, Road Runner and MTSERIES are
permanent and portable axle scales, wheel-load weighers, canister load cell
systems and heavy-capacity platform scales. Much like dynamic weighing systems,
the stationary weighing systems have broad industrial application. Key markets
in which these products enjoy significant market share include, aggregate,
aviation, construction, freight terminals, land remediation, mining and weight
enforcement. Stationary weighing systems utilize the same technology as dynamic
weighing systems; however, they are designed to weigh loads in a static or
stationary mode.

Load Handling and Moving Systems

Load handling and moving systems manufactured and marketed by the Company
utilize both standard and highly specialized air bearing movement systems to
move loads of any weight efficiently and with extreme precision. Air bearings
are air cushion devices that are used to "float" heavy loads on a thin film of
air. 

                                       4

<PAGE>   5
Additionally, the Company manufactures systems utilizing water bearings for
use in large outdoor applications where water is used as the flotation medium
rather than air. These products, marketed under the trade names AeroGo,
AeroCaster, AeroPlanks and AeroPallets, are the world leader in practical and
efficient methods of rotation, alignment, transfer, location and movement of
materials and products weighing from several hundred pounds to more than 6,100
tons.

The Company's load handling and moving product line comprises two distinct
categories. The first is a standard product line of rugged, industrial,
off-the-shelf air cushion devices that allow a single person to easily and
safely move loads weighing from a few hundred pounds to many tons. Standard
products routinely move manufacturing fixtures, printing press bulky paper
rolls, jet engines, and other heavy loads. The other category of the product
line consists of custom-engineered products. Custom-engineered products and
specialized systems designed and manufactured by the Company in recent years are
currently moving 100,000-pound dies, launching ships, moving 4,500-ton stadium
sections, transporting aerospace booster rockets and moving large assemblies in
and out of assembly line operations in numerous heavy equipment manufacturing
facilities.

Additional examples of custom-engineered products include: automated guided
vehicle systems, transporters, turntable systems, precision positioning systems,
precision work holding fixtures, handling fixtures, quick die/mold changing
carts, caisson manufacturing and moving systems and aircraft radar checking
turntables.

SI load handling and moving products commonly represent significant economic
benefit in comparison to conventional material handling equipment through lower
capital investment in site preparation and system installation, greater
operating efficiencies based on system versatility (not limited to following
rails or tracks). They often become the most viable means for handling extreme
applications involving very heavy loads and precision movement.

Force Measurement Devices and Instrumentation

Force measurement devices (FMDs), a core SI technology, are electromechanical
components that convert a physical force to an electrical signal. When matched
with microprocessor-controlled digital electronics, FMDs measure forces such as
pressure, weight, mass and torque. Commercially, force measurement devices are
used in electronic scales and a wide range of machinery and equipment. SI
instrumentation is normally designed as an integral part of a complete weighing
system. In recent years, SI instrumentation has been expanded to provide users
with the ability to acquire, record in memory and download to management
information systems operational information other than weight information. In
this expanded capacity, SI instrumentation becomes a critical link between
operations and management information systems.

Operations Information Systems

Operations information systems, composed of on-board vehicle/equipment computers
and base operation hardware and software, develop information used to manage and
improve the performance of material handling and transportation operations.
System utilization benefits include increased operations efficiency, lower
equipment maintenance costs, better safety records, reduced manual report
generation and improved customer service.



MARKETING AND SALES

The Company's products are marketed throughout the world primarily through 300
distributors and commission-based manufacturer representatives, each operating
in a specific trade area and serving industrial customers, engineering firms and
various government agencies. In addition to headquarters marketing and sales
personnel including management personnel, and telemarketing operations, the

                                       5

<PAGE>   6
Company maintains a warehouse and service center in British Columbia, Canada and
regional sales offices in Alberta, Canada; California, Indiana, Maine, Michigan,
North Carolina, Oregon and Texas. Company regional sales personnel assist
distributors and representatives, make direct sales call on potential customers
in areas not covered by distribution, and support the Company's direct national
accounts.

The Company generates leads through a full complement of marketing practices
including advertisement in industry publications, direct mail advertising,
direct fax advertising, trade show participation and telemarketing. Headquarters
personnel initiate the Company's sales process on all inquiries by providing the
inquirer with information on Company products and services and qualifying the
lead. After qualification, inquiries are either maintained in sales for
follow-up by Company sales personnel and distribution, or dispatched to
engineering for design, cost estimating and preparation of price quotations or
bid packages.

Due to the Company's mix of standard off-the-shelf products and
custom-engineered products the time period between initial inquiry, purchase
order receipt and shipment varies widely. Standard product orders are normally
shipped within one to three days of purchase order receipt at published prices
and with trade terms of FOB factory and 30 days net. Engineered products and
projects are subject to specific contract terms negotiated between the Company
and customer. Typically, contract terms provide for progress payments, provision
for change orders and, on longer-term projects, provision for inflation-based
price adjustment.

All sales outside of the US and Canada are either US dollar denominated or
payable in currencies with fixed exchange rates against the dollar. The majority
of the Company's foreign sales are secured by irrevocable letters-of-credit
drawn on major commercial banks. On certain projects, the Company provides
complete site preparation, system installation, start-up and customer training
services. In this capacity, from time to time, the company serves as contractor
on a time and material basis.



MARKET CONDITIONS AND COMPETITION

Market Conditions

Worldwide capital expenditures for weighing and material handling equipment and
systems have averaged about $30 billion in recent years, with domestic spending
accounting for approximately 30% of the total. The industry is mature and
overall growth is negligible. Although the overall industry is mature, the
Company believes their unique products, diversity of markets and worldwide
geographic presence present significant opportunities for internal growth within
the industry. Additionally, the high fragmentation of the industry provides
similar opportunities for execution of the Company's consolidation acquisition
strategy.

Product uniqueness (niche products) is a competitive advantage for SI.
Manufacturers of conventional mature products competing for market share with
non-differentiated products normally compete primarily on product price and
availability. SI's unique products such as dynamic weighing and air-bearing load
handling and moving systems frequently compete within the industry as substitute
products or as an alternative means for meeting the customers' needs. As a
result of this high level of product differentiation and the application
versatility of SI's unique products, the Company believes demand for SI products
is more elastic than demand for conventional products within the industry. Also,
as expected with highly differentiated products, SI products have historically
produced gross margins higher than the industry average.

Market diversity is a growing competitive advantage for SI. Over the past
eighteen months, SI has been redirecting its focus to new markets in an effort
to mitigate a sharp capital spending downturn in the Company's traditionally
strong forestry and waste management markets. Since the 1996 acquisition of
Evergreen Weigh and Load Measurement Corporation, cross-selling of products and
integration of the sales 

                                       6

<PAGE>   7
organizations have steadily increased revenues in the aggregate, agriculture,
aviation, construction and mining industries. With the acquisition of AeroGo
late in fiscal 1997, the Company has further expanded its market diversity and
potential for revenue synergies. The Company intends to capitalize on its
growing market diversity, worldwide presence and cross-selling opportunities
with an expanding product line to create internal growth.

SI maintains inventories of raw materials, work-in-process and finished goods.
To supply products with competitive availability, the Company carries
approximately 41% of inventory in finished goods. While the Company
manufacturers the majority of its value-added components, certain components,
manufacturing processes and sub-assemblies are outsourced. Outsourced items are
normally purchased on fixed price contracts on a just-in-time basis. Should the
need arise, the Company believes that any supplier and/or subcontractor could be
replaced without significant disruption to its business.

Competition

Competition in the weighing and material handling equipment and system industry
is extremely fragmented with approximately 5,000 manufacturers and a greater
number of distributors and service companies. To the Company's knowledge, there
are no competitors with the same product mix as SI. Direct competitors
(competing head to head with similar products) normally compete on a single
product line and are all smaller and have less financial resources than SI.
General industry-wide competitors (competing with alternative conventional
products) range from very small local companies to large international companies
with greater financial resources than SI.

In the dynamic and stationary weighing systems product line, direct competitors
are all smaller privately held companies. Occasionally and on specific
applications, the weighing systems product line competes as an alternative
product with larger companies who manufacture conventional weighing systems.
These companies include Cardinal Scale Manufacturing Company, Fairbanks Scale
Company, Mettler-Toledo Holding, Inc. and Weigh-Tronix, Inc. Competition among
larger manufacturers of conventional weighing systems due to lack of product
differentiation is principally based on price, local dealer trade area presence
and relationships, and product availability.

Competition in load handling and moving products is similar to weighing system
products. In the air and water bearing product line, all competitors are smaller
privately held companies with less financial resources than the Company. Direct
competitors include, Airfloat, Hovair, and Aircaster. In custom-engineered
products and projects, the Company normally competes as a substitute or
alternative product versus conventional material handling equipment manufactured
by companies ranging in size from much smaller to significantly larger than the
Company.

International markets vary widely in competitive issues. In some countries,
price competition is more intense than in North America, while in others, prior
relationships and product quality receive more customer emphasis than do
marginal pricing differentials, thus price competition is less intensive. As a
result of product uniqueness, innovative design solutions, quality of product
and dependability, SI products and services are frequently sold in situations
where the Company is not the low bidder.

Significant Customers

Historically the Company's primary customers have been transportation,
agriculture, forestry, waste management and general industrial companies.
Through the acquisition of Evergreen Weigh and AeroGo, the Company's customer
base has expanded to include the aerospace, aggregate, automotive, aviation,
construction and maritime industries. Significant customers in recent years
include Boeing, Caterpillar, Chrysler, Continental Airlines, Ford, Hyundai,
Lockheed, Michelin, Mitsubishi, NASA, Paccar, Safeway, Waste Management and
Weyerhaeuser.

                                       7

<PAGE>   8
While a significant portion of the Company's annual revenues represent repeat
business from its customers, no individual customer represents 10% or more of
the Company's revenues on an on-going basis. However, from time-to-time, a
specific engineered products project may exceed 10% or more of the Company's
revenue and for the financial period in which the project is completed an
individual customer may represent 10% or more of the Company's revenue.
Completion of an approximate $1.7 million project with Hyundai Construction in
July following the acquisition of AeroGo represented such an occurrence in 1997.
As a result, Hyundai Construction represented 13% of the Company's revenues in
fiscal 1997.


ACQUISITION HISTORY

Acquisition of Lodec, Inc.

In March 1990, the Company acquired Lodec, Inc., a Washington corporation. As a
manufacturer of dynamic and stationary weighing systems, Lodec was a direct
competitor of the Company at the time of acquisition. Lodec's primary product at
the time of acquisition was an on-board weighing system. On-board weighing
systems, which are designed and built to be installed in the suspension of
industrial vehicles and material handling equipment, provide user operations
with accurate incremental loading and delivery weight information. The use of
on-board scales allows fleet operations to load maximum legal weights at remote
locations and provide a record of changes in payload weights without the
necessity of driving to commercial truck scales between loading and unloading
locations. The acquisition of Lodec increased the Company's market share in
on-board weighing systems, expanded the product line through the addition of
Lodec stationary and portable axle scales, and brought the Company an
international dealer organization in Latin America, Europe, and Asia. In January
of 1991, the Company consolidated all Lodec operations into the corporate
operation in Tukwila, Washington.

Asset Purchase from Advanced Recording Instruments, Inc.

In October 1995, the Company purchased the assets of Advanced Recording
Instruments, Inc. (ARI). The asset purchase included the ARI on-board recorder
and operations information system product lines, all related technology, trade
names, inventory and fixed assets. ARI products, composed of on-board
vehicle/equipment computers and base operation hardware and software, develop
information used to manage and improve the performance of material handling and
transportation operations. System utilization benefits include increased
operations efficiency, lower equipment maintenance costs, better safety records,
reduced manual report generation and improved customer service. Acquisition of
the ARI product line strengthened the Company's ability to serve a growing
customer demand for operations information useful for improving the performance
of material handling and transportation operations.

Acquisition of Evergreen Weigh, Inc.

In April 1996, the Company acquired Evergreen Weigh, Inc. (EW), a Washington
corporation. Evergreen Weigh is a manufacturer of dynamic and stationary
weighing systems. Evergreen's primary products include weigh-in-motion on-board
scales for material handling equipment, axle scales and wheel-load weighers. One
of Evergreen's most notable products, the MT series mining truck scale, is a
portable aluminum-alloy axle scale capable of weighing up to one million pounds.
The proprietary load handling design and manufacturing techniques used in
production of this unique scale make EW a world leader in high-capacity off-road
weighing applications. Key markets served by Evergreen products include the
heavy construction, quarry, mining, aviation and transportation industries. The
acquisition of Evergreen Weigh expanded the Company's product line and increased
the number of markets in which the Company sells products. SI and EW sales
organizations began cross-selling immediately following the acquisition and
merged into one integrated sales organization in early 1997. Evergreen Weigh
operations were consolidated into the Company's Tukwila operation in June of
1997.

Asset Purchase from Load Measurement Corporation

In June 1996, the Company purchased the assets of Load Measurement Corporation
(LMC). The asset purchase included the LMC on-board weighing system product
lines, all related technology, trade names and inventory. LMC products are
designed for and marketed primarily to the agriculture industry.

Acquisition of AeroGo, Inc.

In July of 1997 the Company acquired AeroGo, Inc. a Washington corporation.
AeroGo is a world leader in the design and manufacture of load handling and
moving systems. AeroGo products utilizing both standard and highly specialized
air bearing movement systems are marketed chiefly to aerospace, automotive,
construction, maritime and general industry. Air bearings are air cushion
devices that are used to "float" heavy loads on a thin film of air. In addition,
the Company manufactures water bearings for use in large outdoor applications
where water is used as the flotation medium rather than air. AeroGo load
handling and moving technology has excelled in practical and efficient methods
of rotation, alignment, transfer, location and movement of materials and
products weighing from hundreds of pounds to more than 6,100 tons.

AeroGo's expertise lies in the design and manufacturing of heavy load moving
equipment, die carts, automated guided vehicle systems, transport skates,
sideloaders, and step conveyors. The Company's air bearing systems are designed
to move very heavy loads with extreme precision. In addition, the Company
manufactures a line of rugged, industrial, off-the-shelf air cushion devices
that allow a single person to easily and safely move loads weighing many tons.
AeroGo equipment routinely moves manufacturing fixtures, printing press bulky
paper rolls, jet engines, and other heavy loads. Various specialized systems
designed and manufactured by the Company are currently being used to move
100,000-pound dies, launch ships, move 4,500-ton stadium sections, and transport
aerospace booster rockets.

AeroGo's technology allows extremely heavy loads to be moved over factory floors
and other surfaces without the use of more expensive overhead cranes, or the
engineering and construction costs required to install highly specialized, but
much less practical, mechanical systems. AeroGo equipment allows companies to
build large structures on an assembly line, and then move them in an
omni-directional path on a nearly frictionless film of compressed air.

In October 1997, the Company consolidated the manufacture of all
Company-fabricated products into the AeroGo operation in Tukwila, Washington.

Research & Development

The Company conducts ongoing research and development to refine and improve its
existing product line and to develop new products. Research and development
expenses were approximately $802,427 in the fiscal year ended July 31, 1997 as
compared with $1,171,792 and $970,547 in the fiscal years ended July 31, 1996 
and 1995, respectively. In recent years, the company has focused the majority 
of its development resources on the extension of the weighing system product 
line. In the near term, a higher percentage of these resources will be shifted 
to focus on expansion of the load handling and moving product line. The Company
considers continuing product development to maintain the competitive advantage 
of product differentiation a key component of the Company's internal growth 
plan.

Backlog

At July 31,1997 the company's backlog was $2,169,317, compared with $739,424 on
July 31, 1996. The Company's backlog consists of written orders and commitments
believed to be firm and shippable in fiscal 1998, and in comparison to 1996
includes backlog attributable to AeroGo. Purchase orders and contracts for
products and services are from time to time modified and/or canceled by mutual
consent between SI and the customer. Therefore, backlog on any specific date may
not be reflective of the Company's future performance.

Employees

At July 31, 1997 the Company employed approximately 150 full-time personnel.

Sources of Supply

The materials and components used by the Company to manufacture its products are
available from a variety of sources. The Company believes that it is not
dependent at this time on any particular supplier for either its materials or
components and has experienced no difficulty in obtaining supplies.

Patents and Trademarks

The Company holds eight patents on various force measurement devices and
weighing system design applications. The patents have expiration dates ranging
from 2004 to 2016. Currently the Company has five patents pending approval. The
company also has patent license agreements to build force measurement devices
under patents held by others. The license agreements are fully paid up and
irrevocable for the lifetime of these patents. The Company has no reason to
believe its patents are not valid. However, if the patents were successfully
contested, management does not believe it would have a material adverse impact
on the Company.



FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS AND EXPORT SALES

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

As an aid to understanding the Company's operating results, the following table
indicates the percentage of revenues that each income statement item represents
and the percentage increase or decrease in such items for the years indicated.
Since 1990 the Company has acquired five businesses. As a result of the impact
of these acquisitions, and the integration of the acquired operations on the
Company's business, results of operations for prior periods are not necessarily
comparable with or indicative of operations for current or future periods.

Due to the recent acquisition of AeroGo, a higher percentage of the Company's
revenues in future periods will result from long-term contracts. The Company
records revenues from long-term contracts using the percentage-of-completion
method. Using this method, the Company recognizes revenues based on the
percentage that incurred costs bear to the total estimated costs at completion. 
On contracts extending over more than one fiscal period, analysis of cost and 
profits are made periodically and revisions are reflected in the accounting 
period in which adjustments are determined to be appropriate. Historically, 
AeroGo has experienced quarterly fluctuations in operating results, partially 
as a result of customer budgetary and procurement processes. Typically, SI's 
core weighing systems business, due to the seasonality of key markets and the 
AeroGo business, due to customer budget timing, have experienced greater 
revenues and net income in the second, third and fourth quarters than in the 
first quarter.

RESULTS OF OPERATIONS

REVENUES

Revenues for the year ended July 31, 1997 increased 16% to $12,894,711, from
$11,087,537, for the year ended July 31, 1996. Revenues from new weighing
systems and load handling and moving products, and increased sales to new
markets for weighing systems more than offset decreased weighing system sales to
the Company's traditionally strong forestry and waste management markets. Prior
to recent product line and customer base expansion, nearly 70% of the Company's
revenues were generated in the forestry and waste management industries. Since
early 1996, both of these industries have decreased capital equipment
expenditures as a direct result of declining pulp prices. The decline of pulp
prices from approximately $1,200 per ton in early 1996 to the current level of
approximately $350 per ton has sharply affected the profitability of pulp
producing forestry operations and the recycling operations of waste management
companies. To address profitability issues, both industries have entered into a
period of capacity consolidation. The Company does not anticipate a significant
increase in capital spending in these industries in fiscal 1998.

The April 1996 acquisition of Evergreen Weigh expanded the Company's weighing
systems product line and created significant cross-selling and product-bundling
opportunities in several new markets including the aviation, aggregate and
mining industries. As a result, 1997 revenues benefited from growth of Evergreen
Weigh and traditional SI products in these markets. Current year revenues
additionally reflect full-year contribution of Evergreen Weigh sales in
comparison to four months in 1996 following the acquisition. The July 1997
acquisition of AeroGo further expanded the Company's product line and customer
base in accordance with its consolidation growth strategy. The acquisition
represents the Company's entrance into the material handling equipment industry
with AeroGo load handling and moving equipment and systems. Traditionally,
significant markets for load handling and moving products include the aerospace,
automotive, construction, and maritime industries. Current year revenues
benefited from approximately $2.2 million in AeroGo sales following the
acquisition. Continued execution of the Company's consolidation strategy is
expected to further diversify the Company's product line and customer base
thereby minimizing revenue dependency on any given industry.

Revenues for 1996 increased 13% or $1,271,526 over 1995 revenues of $9,816,011.
Increased sales of new products developed internally for state department of
transportation weight enforcement programs and general freight industries, and
new products and new markets from the acquisition of Evergreen Weigh were
significant contributors to this growth. Results for 1996 included approximately
$800,000 in Evergreen Weigh revenues following the April 1996 acquisition.

International sales accounted for 42% and 36% of total Company sales in 1997 and
1996 respectively, and 41% of sales in 1995. Canadian sales are transacted in
Canadian dollars. International sales outside of Canada are transacted in U.S.
dollars. Due to negligible fluctuation of the Canadian dollar exchange rate,
there has not been a significant impact on the financial statements for foreign
currency exchange.

GROSS PROFIT

Gross profit for the year ended July 31, 1997 increased 8% to $5,745,036, from
$5,316,227 for the year ended July 31, 1996. This increase in gross profit is
directly attributable to higher sales volume. The corresponding gross margins
for the periods were 44.5% and 48.0%, respectively. The decrease in gross margin
resulted from increased price pressure for products serving the forestry and
waste management industries and start-up efficiencies associated with relocating
the manufacture of Evergreen Weigh products into the Company's primary
manufacturing facility.

<PAGE>   15
Gross profit for the year ended July 31, 1996 increased 12% to $5,316,227 from
$4,743,188 for the year ended July 31, 1995. Increased gross profit resulted
from increased sales volume. Corresponding gross margins for the periods were
48.0% and 48.3%, respectively. Variations in gross margin reflect varying
product mixes and the costs of bringing new products into production during the
year.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

Selling, general and administrative expenses for the years ended July 31, 1997
and 1996 were $3,586,262 and $3,061,989, respectively. This 17% increase is
related primarily to the inclusion of Evergreen Weigh operations for a full-year
in 1997 as compared to four months in 1996 following the April 1996 acquisition,
and AeroGo operations for one month following the July 1997 acquisition.

Selling, general and administrative expenses for the years ended July 31, 1996
and 1995 were $3,061,989 and $2,844,831, respectively. This 8% increase resulted
from increased investment in the field sales organization and the inclusion of
Evergreen Weigh operations for four months following the April 1996 acquisition.
These year-over-year expense increases were partially offset by lower
professional service fees in 1996, as compared to 1995.

RESEARCH AND DEVELOPMENT EXPENSES

Research, development and engineering expenses for the years ended July 31, 1997
and 1996 were $802,427 and $1,171,792, respectively. Expenses decreased 32%
year-over-year as the Company completed several product development projects
early in 1997. In recent years, the Company has focused the majority of its
development resources on expansion of the weighing and operations information
system products. In the near term, this focus will be redirected to certain
product development opportunities in the load handling and moving product line.

Research, development and engineering expenses for the years ended July 31, 1996
and 1995 were $1,171,792, and $970,547, respectively. Expenses increased 21% in
1996 as compared to 1995 due to initiation of several projects in 1996.

AMORTIZATION EXPENSE

Amortization expense was $125,598 and $96,774 for the years ended July 31, 1997
and 1996, respectively. The increase was primarily a result of the acquisitions
of Evergreen Weigh and AeroGo. Amortization expense for the year ended July 31,
1995 was $130,443.

INTEREST AND OTHER INCOME/EXPENSE

Interest expense for 1997 increased $178,753, to $291,108, from $112,355 in
1996. This increase in interest expense reflects the costs of the additional
borrowings required to finance the Evergreen Weigh and AeroGo acquisitions.
Interest expense in 1995 was $118,754.

Other income(expense), net resulted in an expense of $5,956 in 1997 as compared
to an income of $57,288 in 1996. In 1996, other income, net increased $37,945,
to $57,288, from $19,343 in 1995. 1996 other income, net included the
non-recurring recovery of a previously written off bad debt.

INCOME TAXES

Income tax expense for the years ended July 31, 1997 and 1996 was $351,000 and
$349,416, respectively. The Company's effective tax rate in 1997 was 37.6% as
compared to 37.5% in 1996. The effective tax rate of 37.6% exceeds the U.S.
federal corporate income tax rate of 34% due primarily to the amortization of
intangible assets that are not deductible for income tax purposes and due to
state income taxes.

Income tax expense in 1996 of $349,416 increased 86% as compared to $187,491 in
1995. The increase resulted from increased pre-tax income and an increase in the
Company's effective tax rate due to the depletion of prior year tax credits. The
Company's effective tax rate in 1996 was 37.5% as compared to 26.9% in 1995.

INFLATION

Historically, the impact of inflation has been negligible, as the Company has
been able to offset the effects through efficiency and price adjustments.

LIQUIDITY AND CAPITAL RESOURCES

At July 31, 1997 the Company's cash position was $128,051 compared to $57,737 at
July 31, 1996. Typically, the Company maintains minimal cash balances. Cash
available in excess of that required for general corporate purposes is used to
reduce borrowings under the Company's line of credit. Working capital decreased
to $433,493 at July 31, 1997 from $2,544,298 at July 31, 1996. The decrease
reflects the $3,000,000 short term financing recorded as a current liability
associated with the acquisition of AeroGo, Inc.

The Company's existing capital resources consist of cash balances, cash provided
by operating activities and funds available under its line of credit. Cash
provided by operations in 1997 was $169,600. During 1996 cash provided by
operations was $121,626.

The Company's cash requirements consist of its general working capital needs,
capital expenditures, obligations under its leases, notes payable and capital
required for future acquisitions. Working capital requirements include the
salary costs of employees and related overhead and the purchase of material and
components. The Company anticipates capital expenditures of approximately 
$250,000 in 1998 as compared to $364,000 in 1997. Excluding payments under the
Company's line of credit, principal payments made under notes payable totaled 
approximately $1,031,000 for the year ended July 31, 1997. In 1998, 
approximately $3,393,000 in principal will be due on notes payable.

In July 1997, the Company amended its principal credit agreement with its bank
for the purpose of financing the acquisition of AeroGo, Inc. This agreement
included an increase to the Company's existing line of credit from $2,000,000 to
$4,000,000, a one year note in the amount of $3,000,000 and a seven year note in
the amount of $1,900,000. The amended credit agreement includes a requirement
that the Company obtain additional equity financing of no less than $3,200,000
no later than July 31, 1998. The Company's credit facility requires the Company
to maintain certain levels of working capital, stockholders' equity and other
covenants.

The Company's $4,000,000 line of credit, maturing November 29, 1998,
continues to be extended as requested. As of July 31, 1997, the Company had
borrowings of $2,174,836 under the line of credit.

The Company believes cash flow from operations, the funds available under its
bank facility and the proceeds of its anticipated equity financing will be
sufficient to meet the Company's working capital needs, anticipated capital
expenditures and payments required under its credit facilities. Future
acquisition activity may require equity capital in excess of the equity 
financing committed to under the Company's existing credit agreement.

               Report of Independent Certified Public Accountants

Board of Directors
SI Technologies, Inc. and Subsidiaries

We have audited the accompanying consolidated balance sheets of SI Technologies,
Inc. and Subsidiaries as of July 31, 1997 and 1996 and the related consolidated
statements of earnings, stockholders' equity, and cash flows for each of the
three years in the period ended July 31, 1997. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of SI Technologies,
Inc. and Subsidiaries as of July 31, 1997 and 1996, and the consolidated results
of their operations and their consolidated cash flows for each of the three
years in the period ended July 31, 1997, in conformity with generally accepted
accounting principles.

                     SI Technologies, Inc. and Subsidiaries
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                          July 31, 1997, 1996 and 1995


NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SI Technologies, Inc. manufactures and markets systems that enhance the
processing, handling and transportation of goods and materials. SI products,
including static and dynamic weighing systems, load handling systems,
measurement devices and instrumentation, and operations information systems,
increase the operational control, safety, efficiency and profitability of its
customers. Sales are made to customers throughout the world. A summary of
significant accounting policies consistently applied in the preparation of the
accompanying consolidated financial statements follows.

1.      Principles of Consolidation

The consolidated financial statements include the accounts of SI Technologies,
Inc. (SI or Company) and its subsidiaries; AeroGo, Inc., Evergreen Weigh, Inc.,
AeroGo Export, Inc., IDEAutomation International, Inc. and Structural
Instrumentation Manufacturing Co. (SI Manufacturing). SI Manufacturing was
merged into SI effective May 1995. All significant intercompany accounts and
transactions have been eliminated in consolidation.

2.      Inventories

Inventories are stated at the lower of cost or market. Cost is determined using
the first-in, first-out method. Uncompleted contracts are included in inventory
at the accumulated cost of each contract not in excess of realizable value.

3.      Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and
amortization. Depreciation and amortization are provided for in amounts
sufficient to relate the cost of depreciable assets to operations over their
estimated service lives, principally on a straight-line basis. Leasehold
improvements are amortized over the lives of the respective leases or the
service lives of the improvements, whichever is shorter. Estimated service lives
of property and equipment are as follows:

<TABLE>
<S>                                               <C>
         Machinery and equipment                  2 to 10 years
         Motor vehicles                           3 to 5 years
         Leasehold improvements                   2 to 10 years
</TABLE>

The straight-line method of depreciation is followed for substantially all
assets for financial reporting purposes, but accelerated methods are used for
tax purposes.

4.      Intangible Assets

Intangible assets represent the excess costs of acquiring subsidiaries over the
fair value of net assets acquired at the date of acquisition which are amortized
using the straight-line method primarily over periods of 25 to 40 years. The
Company periodically reviews goodwill to assess recoverability. Impairment is
recognized in operating results if expected future operating undiscounted cash
flows of the acquired business are less than the carrying value of goodwill.
Accumulated amortization totaled $963,048 and $837,450 at July 31, 1997 and
1996, respectively.

5.      Capitalized Computer Software Costs

Capitalized computer software costs with an amortized cost of $450,700 and
$252,400 at July 31, 1997 and 1996, respectively are reflected as other assets
in the accompanying consolidated balance sheets. These costs are being amortized
over periods ranging from one to three years. Amortization expense charged to
operations relating to these costs totaled approximately $39,700, $23,700 and
$1,500 for the years ended July 31, 1997, 1996 and 1995, respectively.

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - Continued

6.      Product Warranty

Product warranty costs are estimated and accrued at the time sales are recorded.

7.      Revenue Recognition

Sales are recorded at the time of shipment for equipment and for special orders
with relatively short production time requirements. On long-term contracts,
sales are recorded based on the percentage that incurred costs bear to the total
estimated costs at completion. Estimated losses are recorded in total when they
become evident. Accounts receivable include $346,830 and $ 0 at July 31, 1997
and 1996 respectively, of excess costs and related profits over amounts billed.
Such billings are generally made and collected in the subsequent year.

8.      Earnings Per Common and Common Equivalent Share

Earnings per common and common equivalent share is calculated based upon the
weighted average common and common equivalent shares outstanding during the
period.

9.      Foreign Currency Translation

Foreign currency assets and liabilities are translated into their U.S. dollar
equivalents based on year end exchange rates. Revenue and expense accounts are
generally translated at average exchange rates for the appropriate fiscal year.
Aggregate exchange gains and losses arising from the translation of foreign
assets and liabilities are included in stockholders' equity when significant.
Transaction gains and losses are included in income and have not been
significant in amount.

10.     Use of Estimates

In preparing the Company's financial statements, management is required to make
estimates and assumptions that affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the financial statements, and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

11.     Reclassifications

Certain reclassifications have been made to the 1995 and 1996 consolidated
financial statements to conform to the 1997 presentation.

NOTE B - BUSINESS COMBINATION

Effective July 1, 1997, the Company purchased 100% of the common stock of
AeroGo, Inc. (AeroGo) for $6,000,000 in cash. AeroGo is engaged in the
manufacture of load handling equipment. The combination is accounted for under
the purchase method of accounting. The excess of the total acquisition cost over
the fair value of net assets acquired in the amount of $4,347,468 is being
amortized on a straight-line basis over twenty-five years. Earnings include the
results of operations of AeroGo from the acquisition date, July 1, 1997.

of the Company's common stock for aggregate consideration of $1,005,000. During
the 1995 and 1994 fiscal years, the Company repurchased 124,000 shares of common
stock of three of the individuals through payment and has entered into extension
agreements with two other individuals for their 77,000 shares. Under the terms
of these amended put option extension agreements, 65,000 shares are exercisable
during a 150-day period commencing October 2, 1997, and 12,000 shares are
exercisable during a 120-day period commencing October 22, 1997. The Company has
the ability to call the stock at $5 per share at any time during the extension

The currently anticipated liability associated with the Company's agreements to
repurchase 77,000 shares as of July 31, 1997 and 1996, of the Company's common
stock upon exercise of the remaining put options is included in the put option
obligation on the Company's consolidated balance sheet.

The expense associated with these agreements totaled $122,500 and $44,833 for

NOTE J - STOCK OPTION PLAN

The Company implemented a new stock option plan in 1995 and has authorized a
total of 300,000 shares of common stock to be set aside for grants.
Additionally, options are outstanding under the old plan which expired July 31,
1994. The vesting and expiration dates of the stock options are at the
discretion of the Board of Directors.

The Company has adopted only the disclosure provisions of Financial Accounting
Standard No. 123, "Accounting for Stock-Based Compensation" (FAS 123). It
applies APB Opinion No. 25, "Accounting for Stock Issued to Employees," in
accounting for its plans and does not recognize compensation expense for its
stock-based compensation plans. If the Company had elected to recognize
compensation expense based upon the fair value at the grant date for awards
under these plans consistent with the methodology prescribed by FAS 123, the
Company's net income and earnings per share would be reduced to the pro forma
amounts indicated below:


<TABLE>

   Pro forma                   $   503,414      $   555,230


Earnings per common share
   As reported                 $       .24      $       .24
   Pro forma                   $       .20      $       .23
</TABLE>


These pro forma amounts may not be representative of future disclosures because
they do not take into effect pro forma compensation expense related to grants
made before 1995.

The fair value of these options was estimated at the date of grant using the
Black-Scholes option-pricing model with the following assumptions for the
periods ending July 31, 1997 and July 31, 1996, respectively: dividend yields
are nil, expected volatility of 52 and 40 percent; risk-free interest rates of
6.2% and 6.2%; and expected option life of 7.8 years and 6.6 years. The
weighted-average fair value of options granted during the periods ending July
31, 1997 and July 31, 1996 for which the weighted average exercise price equals
the market price on the grant date was $3.63 and $2.36, respectively.

NOTE M - FAIR VALUE OF FINANCIAL INSTRUMENTS

In accordance with the requirements of "Statement of Financial Accounting
Standards No. 107 Disclosure About Fair Value of Financial Instruments", the
following methods and assumptions were used to estimate the fair value of each
class of financial instruments.

1.      Note Payable and Long-Term Debt

The carrying amount approximates fair value because of the variable interest
rates which are consistent with market changes.

2.      Put Option Obligations

It was not practicable to estimate the fair value due to the specific nature of
the contracts.

NOTE N - BENEFIT PLANS

The Company has defined contribution 401(k) plans for each subsidiary. All
employees are eligible for participation upon completion of a waiting period.
The contribution expense associated with these plans totaled approximately
$19,400, $17,000 and $6,800 for the years ended July 31, 1997, 1996 and 1995,
respectively.
