To Our Shareholders

OYO Geospace experienced record growth 
in fiscal year 2006. Revenues increased 42% 
over the previous year’s revenues to $104 
million, setting a new company high. Earnings 
more than doubled to $1.64 per diluted share, 
setting another record. 

Houston Plant Expansion
Achieving these results tested our company’s 
resources, however. Our growth, coupled with 
planned new product releases, contributed to 
our decision to undertake a $12 million plant 
expansion in Houston. Our existing 208,000 
square foot facility will be enlarged by over 80% 
to 378,000 square feet. This expansion gives us 
the needed space to support our growth, but 
more especially to address our acute needs for 
additional manufacturing and engineering space.

The new facility is scheduled to be 
completed in February 2007, followed by 
an additional three months to build out 
and configure operations. The new space 
will be designed to accommodate each of 
our operational divisions, providing a solid 
foundation to match growing and emerging 
market demand.

Russian Plant Expansion
In fiscal year 2006, our operations located in Ufa, Bashkortostan, Russian Federation, 
performed exceptionally well. Our Russian plant produced record amounts of sensor 
products for European and Russian markets and shipped large quantities of sensors to our 
Houston plant to augment its production of sensors.

59188oyoD2R2.indd   1

12/8/06   4:02:22 PM

We installed a small cable manufacturing shop in the Ufa plant to supply leader wire 
for our sensor products and to produce telemetry cables for the local market. This new 
shop is also performing very well.

Growth in our Russian operations, however, has finally become capacity constrained. 
To satisfy our growing demand for these products and to accommodate the release of new 
products, we intend to significantly expand capacity of the Ufa plant. This will require us to 
obtain land and to construct an additional facility. The proposed land for the new facility is 
immediately adjacent to our existing property and will accommodate a new 92,000 square 
foot plant. The Russian plant expansion is scheduled for completion in December 2007.

Exceptional Seismic Exploration Product Demand
OYO Geospace experienced exceptional growth across all its seismic exploration product 
lines. Strong industry demand for geophysical services translated into unprecedented 
demand for new seismic exploration equipment. For our exploration products group, this 
resulted in record demand levels for our sensor products, cables, connectors and for 
marine streamer accessories from our seismic exploration customers. Backlog at the end 
of fiscal year 2006 remains very strong.

Reservoir Characterization Growth
A major growth area for the company lies in our pioneering efforts to provide equipment 
to the new dynamic reservoir characterization equipment market. We received three 
significant contracts in fiscal year 2006. Revenues from two of these projects were 
recognized in fiscal year 2006 while the third is expected to be recognized in the first 
quarter of fiscal year 2007. Total revenue from the contracts is $31.5 million. 

The first contract was for a $7.0 million retrievable bottom cable seismic system for 
the Bureau of Geophysical Prospecting (BGP), a Chinese seismic contractor. This is their 
first bottom cable crew and the system will be used in the international market. We were 
very pleased that BGP, the world’s largest seismic contractor, selected our technology and 
look forward to providing additional equipment to BGP as they expand their operations in 
the bottom cable market. 

The second contract was for an $8.0 million permanent seismic acquisition system 
installed in BP’s Clair Field in the North Sea. The system consists of 2,880 channels and 
covers 38 square kilometers - approximately one third of the field - leaving open future 
opportunities to instrument additional areas in this field. 

The third contract is for a $16.3 million seismic system to instrument BP’s Azeri 

Field in the Caspian Sea. The system consists of 5,360 channels embedded in 67 
kilometers of cables. The Caspian fields are some of BP’s largest and most important 
oil and gas assets. We believe there will be future opportunities to work with BP in the 
Caspian Sea as the contribution of high definition data from reservoir characterization 
continues to be realized.

The growth in fiscal year 2006 of the seismic reservoir market and the increased 
acceptance of our emerging technology products support our decision to expand the 
Houston plant.

Emerging Technologies
OYO Geospace also incubates emerging 
technologies using existing engineering and 
manufacturing resources to enter new markets. 
In fiscal year 2006, this part of our company also 
grew substantially in several market areas. A 
brief discussion of these follows.

Thermal Solutions
Currently, the largest division of our emerging 
technologies group is thermal imaging. 
Growing out of our early seismic plotter 
line, this division primarily provides thermal 
plotters, film and printheads to the commercial 
graphics markets. Non-seismic thermal 
imaging products now dominate the division’s 
customer base and growth. 

This year, the division contributed $15 
million in revenues. Profitability improved this 
year in our thermal solutions group, but still 
does not meet our internal goal for investment 
returns. However, we have identified needed 
improvements and have efforts underway to 
accomplish those goals.  

In addition to these activities, our 

engineering group developed a new direct-to-
screen technology that the thermal solutions 
group is incorporating into a new line of 
products. Rollout for the new product line will

Manager of Manufacturing Operations, oversee the progress of OYO 

Geospace’s Houston, Texas plant expansion.

begin in the first quarter of fiscal year 2007 and should accelerate throughout the remainder 
of the fiscal year. Further development of this new technology is expected to result in new 
products within the next two years. These new direct-to-screen products are expected to 
open new niche markets for the group and we expect that the new product line will be a 
strong vehicle for growth.

Offshore Cable and Umbilicals
Offshore cable and umbilicals is another active emerging market that experienced a year 
of record revenue, despite being constrained by manufacturing limitations. The offshore 
cable and umbilicals group provides long, deepwater cables for the oilfield services 
market. Its products include ROV umbilicals and tethers, BOP cables and cables providing 
power and communications used in even larger underwater cables. 

The offshore cable product line is early in its development, but market acceptance 

grew exponentially in fiscal year 2006. We experienced far more demand for our 

59188oyoD2R2.indd   3

12/9/06   8:49:31 PM

offshore products than our manufacturing processes could possibly fulfill. This was 
due in part to increased demand for our seismic reservoir products and our inability to 
accommodate growth in both markets simultaneously. Our Houston plant expansion is 
expected to address this need. We expect to see another growth year for the offshore 
cable group once our plant expansion is completed in 2007. We are firmly convinced 
that we will be able to serve this new market with quality products and services that 
exceed expectations.

Industrial Sensors
The company’s industrial sensor and cable customers experienced a record year in fiscal 
year 2006. This group provides custom sensors and cables to the earthquake, vibration 
monitoring, border security and other similar markets. This group has grown consistently 
over the past several years by introducing new products in new markets and supplying 
quick engineering and service support. We continue to find new customers and market 
opportunities to grow in these niche markets. 

2006 Performance
We are proud of this year’s performance. 
Although our results yielded a respectable 
23% pretax return on our shareholder equity 
for the year, we continue to see ways to 
improve. Our plant expansion, new product 
offerings, increased acceptance of our 
dynamic reservoir characterization and our 
new direct-to-screen technologies combined 
with continued strong demand for our seismic 
exploration products give us optimism for 
growth in 2007 and beyond. 

I want to take this opportunity to thank

our customers for their continued support. Without them we would not be where we are 
today. I also want to thank our employees. Over the past year much has been asked of 
them and they responded with exceptional performance.  I also want to thank our vendors 
for their support. Their responsiveness to our needs has contributed to our strength this 
year. And finally, I wish to thank our shareholders for their ongoing support.

Sincerely,

Wherever seismic contractors are called, 
Geospace has answers.

The exploration sector of the oil and gas 

industry experienced unprecedented 

activity and growth in 2006, and demand 

for seismic sensor, cable and connector 

products have reached all-time highs. 

Seismic acquisition projects can take 

place in diverse and challenging field 

environments, requiring sophisticated 

and robust seismic sensor equipment. 

Geophysical service contractors depend 

on Geospace Technologies to design, 

manufacture and deliver the equipment 

solutions to meet project specifications in some of the most demanding exploration 

regions in the world. These contractors trust not only our technology, but also our in-depth 

industry knowledge. We understand what our customers need from seismic technology 

– and we understand what their customers need as well.

From deserts to transition zones, Geospace Technologies’ real world experience ensures that we understand our 

customer’s equipment needs.

  One such contractor is Grant Geophysical (now part of Geokinetics, Inc.). Geokinetics 

has trusted Geospace Technologies for more than 25 years to provide seismic recording 

instrumentation, custom seismic cable assemblies and connectors that satisfy the complex 

requirements of its top-tier customer base.

From New Zealand to Latin America, Geokinetics is involved in land seismic and 

transition zone seismic projects worldwide – in some extremely harsh terrain. Transition 

zones in particular are challenging environments. Bridging from land to shallow water and 

into deep water, seismic technology must be built to withstand all the elements, including 

the rigors of land deployment, tidal forces, and the harsh demands of deep water. Seismic 

cabling for transition zones requires a higher level of mechanical integrity to perform in 

these environments. In addition, as more 

contractors utilize mechanical retrieval 

systems for efficiency reasons, cabling 

must be highly robust and durable. 

As its customers look for new energy 

resources in rugged terrain around the 

world, Geokinetics must go the extra 

mile to keep crews safe and projects 

progressing efficiently – and it knows 

equipment from Geospace Technologies 

can keep pace.

Field acquisition of seismic data is logistically 

complex, expensive and sometimes perilous. 

Contractors look to manufacturers like Geospace 

Technologies for robust sensor equipment to 

successfully execute their acquisition projects.

Geospace is helping seismic fleets keep 
pace in a booming market.

Industry experts have characterized 2006 

as one of the busiest years on record 

for seismic vessels, with record-breaking 

backlogs and demand expected to outstrip 

vessel supply around the world. In response, 

seismic fleets are adding new vessels 

and upgrading existing vessels, creating a 

significant market expansion. Geospace 

Technologies was poised to take advantage 

of the opportunity – with the right 

innovations delivered at the right time.

When optimized production is the goal, 
GERI delivers.

World demand to increase oil and gas 

reserves is driving a trend toward 

continuous, real-time management of 

oil and gas reservoirs to ensure optimal 

production. To that end, a growing 

number of oil and gas companies 

are adding reservoir surveillance 

solutions to their field development 

plans. Leading global oil and gas 

companies are investing in both 

permanent and retrievable sea-floor 

surveillance infrastructure to maximize 

their analytical capabilities and allow 

for real-time data collection and 

interpretation. Geospace Engineering  

Resources International (GERI) delivers 

these solutions.

Permanent reservoir surveillance sensor equipment 

helps BP’s Clair Field in the North Sea achieve 

optimal field production.

  Monitoring how the reservoir responds to ongoing production is critical to “life of 

field” reservoir management. Typically, however, producers can only measure reservoir 

conditions close to the wellbore – an expensive and risky undertaking that provides limited 

reservoir response data. But using time-lapse seismic provides a superior approach. After 

calibrating once with wellbore measurements, time-lapse seismic can provide a series of 

field-wide images of the reservoir’s response to production. 

Time-lapse seismic also overcomes problems such as monitoring through gas clouds, 

monitoring thin gas reservoirs, evaluating reservoir fracturing, and locating bypassed oil 

and gas deposits.

Engineers can remotely collect and evaluate time-lapse seismic data that yields a field-wide view of the reservoir’s 

response to oil and gas production with GERI’s permanent reservoir surveillance system.

Monitoring BP’s Clair Field from Houston 

59188oyoD2R2.indd   10

12/8/06   4:02:54 PM

 
GERI is the only company in the  
world with permanent large scale, 
multi-component, reservoir surveillance  
infrastructure solutions in commercial 
operation – and more under way.

These	permanent	sea-floor	systems	allow	oil	and	gas	engineers	to	actively	monitor	

critical	changes	inside	the	reservoir	in	real-time	and	over	the	life	of	the	field.	The	

methodology	allows	for	significant	economic,	efficiency	and	environmental	benefits	

because	the	field	operator	can	collect	critical	reservoir	data	without	drilling	additional	

wells.	Instead,	they	use	detailed	time-lapse	seismic	images	to	characterize	the	reservoir.

In	2006,	GERI	delivered	its	third	

large-scale	permanent	surveillance	

solution	at	BP’s	Clair	Field	in	the	

North	Sea.	The	system’s	permanent	

receivers	give	BP	the	ability	

perform	a	variety	of	tasks,	including	

repeated	conventional	seismic	

and	source	efforts	and	continuous	

microseismic	monitoring.	The	Clair	

Field	system	includes	more	than	

37	kilometers	of	armored	cable,	

houses	746	sensor	stations,	and	

GERI’s advantage over other technology providers is “practical 

knowledge and real-world experience.” Each real-world project 

results in extensive new technical data and knowledge about the 

design, manufacture, deployment and maintenance of permanent 

subsea reservoir surveillance systems. This is a critical system 

asset that no other company can offer its customers.

covers more than eight square kilometers of seafloor. In addition, nearly nine kilometers of 

fiber optic umbilical was used to interconnect seismic sensor lines and the recording system 

to the sensor array. Based on positive results from the industry’s first (and continuing) large-

scale permanent surveillance project in the North Sea’s Valhall Field, it is not unreasonable 

to expect the Clair Field monitoring project to deliver similar life of field benefits.

  Geophysical service contractors are also seeking ways to optimize revenue in this 

time of intense activity. For them, GERI retrievable surveillance solutions are the answer. 

These kinds of customers can deploy retrievable systems for their clients, shoot seismic 

data and provide monitoring for as long as the producer requires. The customer can then 

retrieve the system and move it to another field. In 2006, the Bureau of Geophysical 

Prospecting (BGP), a Chinese seismic contractor, invested in a large-scale retrievable 

system from GERI and is putting it to work 

for clients worldwide. 

  With innovative solutions like these, 

GERI continues to build on its reputation 

for developing and deploying solutions 

characterized by very large channel counts, 

fault tolerant operations, and real-time 

acquisition. Through collection of more and 

better data, engineers can make better 

operational and production decisions over 

the life of a reservoir.

Real-time reservoir monitoring and collection of 

time-lapse reservoir data are not possible without 

robust and reliable sea floor sensor equipment like that 

developed and manufactured by GERI.

Cable and umbilical solutions link 
customers to market rewards.

Like most segments of the oil and gas 

industry, offshore development is running 

at maximum capacity. Many companies 

are focused on initiating production from 

deepwater oil and gas fields discovered 

over the past several years. Lying in 

several thousand feet of water, these 

fields are technically and financially 

challenging – requiring sophisticated 

technology and techniques to bring them 

to production.

  Geospace Offshore is meeting the 

needs of this equipment-constrained 

market in a number of ways. Geospace 

Strategically located just 90 miles from one of the world’s 

Offshore specializes in designing and 

most active offshore hydrocarbon regions, Geospace

factors in today’s offshore market environment.

and tethers and umbilicals for construction-class ROVs (remote operating vehicles) are in 

worldwide demand. In fact, there are approximately 50 deepwater construction-class ROVs 

slated for completion in 2007. 

For everything from inspections to construction to monitoring, ROVs provide critical 

capabilities in deepwater environments and anywhere divers cannot be deployed. Each 

ROV deployment or upgrade is accompanied by a need for quality tethers and cables 

for power and control. Each project moves Geospace Offshore closer to its goal of 

establishing itself as top-tier vendor in this market.

  Geospace Offshore also provides critical electrical components to many of the 

industry’s leading manufacturers of subsea control umbilicals for offshore applications. As 

deepwater well construction intensifies, this market grows as does Geospace Offshore’s 

reputation for quality components, responsive lead times and advantageous logistics. 

Announced in 2006, the expansion of OYO Geospace’s manufacturing facilities in 

Houston, Texas will enable Geospace Offshore to significantly increase manufacturing 

capacity to remain synchronized with industry demand for years to come.

Revolutionary process means 
big productivity gains for customers.

Screen printing is the most common process for creating and transferring images to 

garments and textiles – everything from t-shirts to golf bags. It’s also a massive global 

market. The process, however, has long been labor- and chemical-intensive, requiring a 

series of elaborate steps to stretch, coat, mask and expose the polyester screen. Add 

in multiple drying stages and subsequent chemical washing, drying and restretching for 

reuse, and the entire process takes an hour or more. 

  But now OYO Instruments has developed an innovative process for creating high-

quality screens that can be imaged and ready for printing in a matter of minutes. 

  OYO’s EcoPro® Direct-to-Screen (DTS) technology will enable our printed textile 

customers to dramatically increase throughput and reduce labor and material costs – all in 

a virtually chemical-free printing environment. 

For large-scale textile printing shops, this technology will rapidly pay for itself in 

productivity improvements and reduced film and labor costs. 

For start-ups, the benefits come even faster. 

The compact EcoPro system requires    

The EcoPro DTS system eliminates messy 

production steps and saves significant time when

about the same capital investment as traditional screen printing equipment, which includes 

washout booths, power washers, vacuum frames, exposure lamps, film and chemicals to 

reclaim screens – plus the floor space to house these facilities.

The EcoPro is just the latest innovation from OYO Instruments, a leading manufacturer 

of professional-quality thermal imaging equipment and film products. The business unit 

plans to launch additional textile printing solutions in 2007 to give customers even more 

choices and flexibility.

“We saw tremendous interest in our system at trade shows during 

technology to be rapidly embraced by the industry.”

Item 1. Business

Overview

PART I

OYO Geospace Corporation is a Delaware corporation incorporated on September 13, 1997. Unless
otherwise specified, the discussion in this Annual Report on Form 10-K refers to OYO Geospace Corporation
and subsidiaries. We design and manufacture instruments and equipment used in the acquisition and processing
of seismic data as well as in the characterization and monitoring of producing oil and gas reservoirs. We have
been in the seismic instrument and equipment business since 1980 and market our products primarily to the oil
and gas industry. We also design, manufacture and distribute thermal imaging equipment, and dry thermal film
products targeted at
the screen print, point of sale, signage and textile market sectors. We have been
manufacturing thermal imaging products since 1995. We report and evaluate financial information for each of
these two segments: Seismic and Thermal Solutions.

Seismic Products

The seismic segment of our business accounts for the majority of our sales. Geoscientists use seismic data
primarily in connection with the exploration, development and production of oil and gas reserves to map
potential and known hydrocarbon bearing formations and the geologic structures that surround them.

Seismic Exploration Products

Seismic data acquisition is conducted by combining a seismic energy source and a data recording system.
We provide many of the components of data recording systems, including geophones, hydrophones, seismic
leader wire, geophone string connectors, seismic telemetry cables and other seismic related products. We also
design and manufacture specialized data systems targeted at niche markets. On land, our customers use our
geophones, leader wire, cables and connectors to receive, measure and transmit seismic reflections resulting from
an energy source to data collection units, which store information for processing and analysis. In the marine
environment, large ocean-going vessels tow long seismic cables known as “streamers” containing hydrophones
which are used to detect pressure changes. Hydrophones transmit electrical impulses back to the vessel’s data
collection unit, where the seismic data is stored for subsequent processing and analysis. Our marine seismic
products help steer streamers while being towed and help recover streamers if they become disconnected from
the vessel.

Our products are compatible with most major seismic data systems currently in use, and sales result
primarily from seismic contractors purchasing our products as components of new seismic data systems or to
repair and replace components of seismic data systems already in use.

Our wholly-owned subsidiary in Russia, OYO-GEO Impulse International, LLC (“OYO-GEO Impulse”),
manufactures international standard geophone sensors and related seismic products for the Russian and other
international seismic marketplaces. Operating in foreign locations involves certain risks as discussed under the
heading “Risk Factors—Our Foreign Subsidiaries and Foreign Marketing Efforts Face Additional Risks and
Difficulties”.

Seismic Reservoir Products

We have developed permanently installed high-definition reservoir characterization products for ocean-
bottom applications in producing oil and gas fields. We also produce a retrievable version of this ocean-bottom
system for use on fields where permanently installed systems are not appropriate or economical. Seismic surveys
repeated over selected time intervals show dynamic changes within the reservoir and can be used to monitor the

2

effects of production. Utilizing these products, producers can enhance the recovery of oil and gas deposits over
the life of a reservoir.

In addition, we produce seismic borehole acquisition systems which employ a fiber optic augmented
wireline capable of very high data transmission rates. These systems are used for several
reservoir
characterization applications, including a new application pioneered by us allowing operators and service
companies to monitor and measure the results of fracturing operations. Our customers are deploying these
borehole systems in the United States, Canada and China.

Emerging Technology Products

We have recently expanded our products beyond seismic applications by utilizing our existing engineering
experience and manufacturing capabilities. We now design and manufacture power and communication
transmission cable products for offshore applications and market these products to the offshore oil and gas and
offshore construction industries. These products include a variety of specialized cables, primarily used in
deepwater applications, such as remotely operated vehicle (“ROV”) tethers, umbilicals and electrical control
cables. These products also include specially designed and manufactured cables, including armored cables,
engineered to withstand harsh offshore operating environments.

In addition, we design and manufacture industrial sensors for the vibration monitoring and earthquake
detection markets. We also design and manufacture other specialty cable products, such as those used in
connection with global positioning products.

Thermal Solution Products

Our thermal solutions product

technologies were originally developed for seismic data processing
applications. In 1995 we modified this technology for application in other markets. Our thermal solutions
products include thermal printers, thermal printheads and dry thermal film. Our thermal printers produce images
ranging in size from 12 to 54 inches wide and in resolution from 400 to 1,200 dots per inch (“dpi”). We market
our thermal solutions products to a variety of industries, including the screen print, point of sale, signage and
textile markets. We also continue to sell these products to our seismic customers, though this market comprises a
small percentage of sales of our thermal solutions products.

In April 2002, we acquired intellectual property necessary to manufacture dry thermal film from Labelon
Corporation, our former supplier of dry thermal film (the “Former Primary Film Supplier”). This purchase gave
us exclusive ownership of all technology used by our Former Primary Film Supplier to manufacture dry thermal
film. We are now using this intellectual property to produce our own brand of dry thermal film to sell to the
customers of our manufactured line of thermal printers. We also continue to distribute another brand of dry
thermal film to users of our thermal printers.

On July 3, 2002, the Former Primary Film Supplier filed a Chapter 11 reorganization petition in Federal
Bankruptcy Court for the Western District of New York. At the date of such bankruptcy filing, we had $3.4
million of long-term assets carried on our balance sheet as a result of prior transactions with the Former Primary
Film Supplier (including a $2.3 million investment in intellectual property acquired from the Former Primary
Film Supplier described above).

Shortly thereafter, the Former Primary Film Supplier ceased providing us with dry thermal film. As a result,
we are currently purchasing a large quantity of dry thermal film from an alternative film supplier, and we are
using the technology we purchased from the Former Primary Film Supplier to manufacture dry thermal film
internally.

3

As a result of the bankruptcy filing by the Former Primary Film Supplier, we recorded a $1.2 million charge
in fiscal year 2002 due to the ultimate uncertainty of realization of value on certain assets, particularly certain
prepaid purchase benefits and other benefits under the amended supply contract with the Former Primary Film
Supplier. We continue to believe there has not been any impairment in the value of the intellectual property we
acquired from the Former Primary Film Supplier because we are utilizing such property to manufacture dry
thermal film.

On December 10, 2002, we received a notice of claim, in connection with the Former Primary Film
Supplier’s bankruptcy, for alleged preferential payments made by the Former Primary Film Supplier to us in the
period before the bankruptcy proceeding in the approximate amount of $259,000. On July 7, 2004, an amended
claim was filed against us and the amount of the alleged preferential payments made by the Former Primary Film
Supplier was increased to approximately $895,000. On January 20, 2006, a motion to amend was filed regarding
the claims pending against us. On August 28, 2006, the motion to amend was denied. We intend to continue to
vigorously defend against the remaining claims under the overall circumstances of our relationship with the
Former Primary Film Supplier. At present we do not know whether we will make any claims against the Former
Primary Film Supplier or others, and we are unable to predict whether any additional claims will be made against
us in connection with the Former Primary Film Supplier’s bankruptcy proceeding as to any aspect of our
relationship with the Former Primary Film Supplier. We are unable at this time to predict the outcome and effects
of this situation.

On September 30, 2004, we acquired for $1.8 million the thermal printhead production assets from Graphtec
Corporation (“Graphtec”). Prior to that date, Graphtec was the only supplier of wide-format thermal printheads
that we used to manufacture our wide-format thermal imaging equipment. We concluded the manufacturing of
printheads in Fujisawa, Japan in December 2004 using the assets that we acquired from Graphtec and relocated
those assets, along with certain key employees of the division, to our facility located at 7007 Pinemont Drive in
Houston, Texas (our “Pinemont facility”). In April 2005, we began producing printheads at our Pinemont facility.
As a result, we believe we are now the only manufacturer of wide-format thermal printheads in the world.

The quality of thermal images on film is determined primarily by the interface between a thermal printhead
and the thermal film. As a result of our acquisition of intellectual property from our Former Primary Film
Supplier and acquisition of thermal printhead production assets from Graphtec, we are now manufacturing
thermal printheads and thermal film, which we believe will enable us to more effectively match the
characteristics of our thermal printers to thermal film, thereby improving print quality, and make us more
competitive in markets for these products.

We also distribute another brand of generally high-quality dry thermal film to users of our thermal printers.
This other brand of dry thermal film can be abrasive to our thermal printheads, resulting in high warranty costs
associated with the replacement of damaged printheads. We are attempting to modify our thermal printheads so
that they interface better with this other brand of dry thermal film. In addition, we are engaged in efforts to
develop a new line of dry thermal film in order to improve the image quality of our own film for use with our
printheads and thus reduce our reliance on the other brand of dry thermal film that tends to be abrasive to our
printheads. Both efforts to modify our printheads and to improve our film have been on-going in recent periods,
but at this time we are unable to provide any assurance that we can eliminate printhead and film interface issues
in the near future or at all. In order to achieve more than marginal growth in our thermal solutions product
business in future periods, we believe that it is important to continue our concentration of efforts on both our
printhead changes and film improvements.

Products and Product Development

Seismic Products

Our seismic product lines currently consist of high definition reservoir characterization products and
services, geophones and hydrophones, including multi-component geophones and hydrophones, seismic leader

4

wire, geophone string connectors, seismic telemetry cables, marine seismic cable retrieval and steering devices
and specialized data acquisition systems targeted at niche markets. Our seismic products are compatible with
most major seismic data acquisition systems currently in use. We believe that our seismic products are among the
most technologically advanced instruments and equipment available for seismic data acquisition.

Our products used in marine seismic data acquisition include our patented marine seismic streamer retrieval
devices (“SRDs”). Occasionally, streamers are severed and become disconnected from the vessel as a result of
inclement weather, vessel traffic or human or technological error. Our SRDs, which are attached to the streamers,
contain air bags that are designed to inflate automatically at a given depth, bringing the severed streamer to the
surface. These SRDs save the seismic contractor significant time and money compared to the alternative of
losing and replacing the streamer. We also produce seismic streamer steering devices, or “birds,” which are
finlike devices that attach to the streamer and help maintain it at a certain desired depth as it is towed through the
water.

Other product developments include the HDSeis™ product line and a suite of borehole and reservoir
characterization products and services. Our HDSeis™ System is a high definition seismic data acquisition system
with flexible architecture that allows it to be configured as a borehole seismic system or as a subsurface system
for both land and marine reservoir-monitoring projects. The scalable architecture of the HDSeis™ System
enables custom designed system configuration for applications ranging from low-channel engineering and
environmental-scale surveys requiring a minimum number of recording channels to high-channel surveys
required to efficiently conduct permanent deepwater reservoir imaging and monitoring. Modular architecture
allows virtually unlimited channel expansion with global positioning systems and fiber-optic synchronization. In
addition, multi-system synchronization features make the HDSeis™ System well suited for multi-well or multi-
site acquisition, simultaneous surface and downhole acquisition and continuous reservoir monitoring projects.

Reservoir characterization requires special purpose or custom designed systems in which portability
becomes less critical and functional reliability assumes greater importance. This reliability factor helps assure
successful operations in inaccessible locations over a considerable period of time. Additionally, reservoirs
located in deepwater or harsh environments require special instrumentation and new techniques to maximize
recovery. Reservoir characterization also requires high-bandwidth, high-resolution seismic data for engineering
project planning and reservoir management. We believe our HDSeis™ System and tools, designed for cost-
effective deployment and lifetime performance, will make borehole and seabed seismic acquisition a cost-
effective and reliable process for the challenges of reservoir characterization and monitoring.

Our recent 3D seismic product developments include an omni-directional geophone for use in reservoir
monitoring, a compact marine three-component or four-component gimbaled sensor and special-purpose
connectors, connector arrays and cases.

In order to take advantage of our existing seismic cable manufacturing facilities and capabilities, we are
designing and selling new cable products to the offshore oil and gas and offshore construction industries. The
production of marine cables requires specialized design capabilities and manufacturing equipment, which we also
utilize for deepwater reservoir characterization products. We are also working to diversify our existing seismic
product lines and adapt our manufacturing capabilities for uses in industries other than the seismic industry.

Thermal Solutions Products

Our thermal solutions products include thermal printers, thermal printheads and dry thermal film. We
market these products to a variety of industries, including the screen print, point of sale, signage and textile
markets. We also sell these products to our seismic customers.

We design, manufacture and sell thermal printers with data images ranging in size from 12 to 54 inches
wide and resolution ranging from 400 to 1,200 dpi. We also manufacture our own line of thermal film products

5

as well as distribute another brand of thermal film to the users of our thermal printers. In our thermal solutions
segments, we derive revenue primarily from the sale of thermal solutions products to our commercial graphics
customers.

Competition

Seismic Products

We believe that we are one of the world’s largest manufacturers and distributors of seismic related products.
The principal competitors in our seismic business segment for geophones, hydrophones, geophone string
connectors, leader wire and telemetry cable are Input/Output, SERCEL (a division of Compagnie Générale de
Géophysique, or CGG) and Steward Cable. Furthermore, an entity in China affiliated with SERCEL, as well as
certain other Chinese manufacturers, produce a geophone having the same design and specifications as one of our
older modeled geophones. The Chinese entity affiliated with SERCEL has recently announced its intent to
develop a modern low-cost geophone meeting current industry standards and specifications. In addition to these
competitors, certain manufacturers of marine streamers also manufacture hydrophones for their own use.

We believe that the principal competitive factors in the seismic instruments and equipment market are
technological superiority, product durability and reliability, and customer service and support. Since price and
product delivery are also important considerations for customers, pricing terms may become more significant
during an industry downturn. These factors can be offset by a customer’s preference for standardization. In
general, some customers prefer to standardize geophones and hydrophones, particularly if they are used by a
single seismic crew or multiple crews that can support each other. These customers’ desire for standardization
makes it more difficult for a geophone or hydrophone manufacturer to gain market share from other
manufacturers with existing relationships with the customers.

As mentioned above, a key competitive factor for seismic instruments and equipment is durability under
harsh field conditions. Instruments and equipment must not only meet rigorous technical specifications regarding
signal integrity and sensitivity, but must also be extremely rugged and durable to withstand the rigors of field
use, often in harsh environments.

With respect to our marine seismic data products, we are not aware of any competing companies that
manufacture a product functionally similar to our patented seismic streamer retrieval device. We believe our
primary competitor in the manufacture of our streamer depth positioning device, or “birds,” is Input/Output.

We believe our primary competitors for our deepwater cabled reservoir characterization and monitoring
systems are traditional seismic equipment manufacturers or equipment providers such as WesternGeco
(Schlumberger), Input/Output, SERCEL and some newly formed alliances involving these companies.

We believe our primary competitors for high definition borehole seismic data acquisition systems are

Avalon and CGG.

Thermal Solutions Products

We believe that the primary competitors in our thermal imaging business segments are Ricoh, Xante, Gerber
Scientific, iSys Group, Cypress Tech., and Atlantek, as well as manufacturers of alternative technologies such as
inkjet printing. Also, as we advance the resolution capabilities of direct thermal imaging technology, we expose
ourselves to additional competition in the more traditional wet-film imagesetting marketplace. A key competitive
factor in this market is producing equipment that is technologically advanced yet cost effective.

6

Suppliers

Prior to our acquisition of thermal production assets from Graphtec described above under the heading
“Business—Thermal Solutions Products,” Graphtec was the only supplier of wide-format thermal printheads that
we use to manufacture our wide-format thermal imaging equipment. We now manufacture printheads internally
using assets acquired from Graphtec.

We produce dry thermal film internally using the intellectual property purchased from our Former Primary
Film Supplier, discussed above under the heading “Business—Thermal Solutions Products.” We also purchase a
substantial quantity of dry thermal film from another supplier.

We do not currently experience any significant difficulties in obtaining raw materials from our suppliers for

the production of seismic products or thermal imaging equipment products.

Product Manufacturing and Assembly

Our manufacturing and product assembly operations consist of machining or molding the necessary
component parts, configuring these parts along with components received from various vendors and assembling a
final product. We manufacture seismic equipment to the specifications of our customers. For example, we can
armor cables for applications such as deepwater uses. We assemble geophone strings and seismic telemetry
cables based on a number of customer choices such as length, gauge, tolerance and color of molded parts. With
regard to dry thermal film, we mix and react various chemicals to formulate a reactive layer that is then coated
onto a clear polyester film. The film is then coated with a protective topcoat that produces the final product.
Upon completion, we test our final products to the functional and,
in the case of seismic equipment,
environmental, extremes of product specifications and inspect the products for quality assurance. We normally
manufacture and ship our products based on customer orders and, therefore, typically do not maintain significant
inventories of finished goods for sale.

Markets and Customers

Our principal seismic customers are seismic contractors and major independent and government-owned oil
and gas companies that either operate their own seismic crews or specify seismic instrument and equipment
preferences to contractors. For our deepwater reservoir characterization products, our customers are generally
large international oil and gas companies that operate long-term offshore oil and gas producing properties. Our
thermal imaging customers primarily consist of direct users of our equipment as well as specialized resellers that
focus on the newsprint, silkscreen and corrugated box printing industries. None of our customers comprised more
than 10% of our sales for fiscal years 2006, 2005 or 2004. The following table describes our sales by customer

Intellectual Property

We seek to protect our intellectual property by means of patents, trademarks, trade secrets and other
measures. Although we do not consider any single patent essential to our success, we consider our patent

7

regarding our marine seismic cable retrieval devices to be of particular value to us. This patent is scheduled to
expire in 2012. Our dry thermal film technology patents expire at varying dates beginning in 2013.

Research and Development

We expect to incur significant future research and development expenditures aimed at the development of
additional seismic data acquisition products to be used for high definition reservoir characterization in both land
and marine environments and thermal imaging technologies. We have incurred company-sponsored research and
development expenses of $6.6 million, $5.0 million and $4.8 million during the fiscal years ended September 30,
2006, 2005 and 2004, respectively.

Employees

As of September 30, 2006, we employed approximately 975 people predominantly on a full-time basis, of
which approximately 483 were employed in the United States and approximately 447 in Russia. Our employees
in Russia belong to a national union for machine manufacturers. Our remaining employees are not unionized. We
have never experienced a work stoppage and consider our relationship with our employees to be satisfactory.

Item 1A. Risk Factors

Risk Factors

Commodity Price Levels May Affect Demand for Our Products

Demand for many of our products depends primarily on the level of worldwide oil and gas exploration
activity. That activity, in turn, depends primarily on prevailing oil and gas prices and availability of seismic data.
Historically, the markets for oil and gas have been volatile, and those markets are likely to continue to be
volatile. Oil and gas prices are subject to wide fluctuation in response to changes in the supply of and demand for
oil and gas, market uncertainty and a variety of additional factors that are beyond our control. These factors
include the level of consumer demand, weather conditions, domestic and foreign governmental regulations, price
and availability of alternative fuels, political conditions and hostilities in the Middle East and other significant
oil-producing regions, increases and decreases in foreign supply of oil and gas, prices of foreign imports and
overall economic conditions. Any unexpected material changes in oil and gas prices or other market trends that
adversely impacts seismic exploration activity would likely affect the demand for our products and could
materially and adversely affect our results of operations and liquidity.

Our New Products May Not Achieve Market Acceptance

Management’s outlook and assumptions are based on various macro-economic factors and internal
assessments, and actual market conditions could vary materially from those assumed. In recent years, we have
incurred significant expenditures to fund our research and development efforts, and we intend to continue those
expenditures in the future. However, research and development is by its nature speculative, and we cannot assure

8

you that these expenditures will result in the development of new products or services or that any new products
and services we have developed recently or may develop in the future will be commercially marketable or
profitable to us. In particular, we have incurred substantial expenditures to develop seismic products for reservoir
characterization applications. In addition, we try to use some of our capabilities, particularly our cable
manufacturing capabilities, to supply products to new markets. Further, we have incurred substantial expense and
expended significant effort to develop our thermal solutions products. We cannot assure you that we will realize
our expectations regarding acceptance of and revenues generated by our new products and services in existing or
new markets.

We May Experience Fluctuations in Quarterly Results of Operations

Historically, the rate of new orders for our products has varied substantially from quarter to quarter.
Moreover, we typically operate, and expect to continue to operate, on the basis of orders in hand for our products
before we commence substantial manufacturing “runs.” The nature of our order backlog generally does not allow
us to predict with any accuracy demand for our products more than approximately three months in advance.
Thus, our ability to replenish orders and the completion of orders, particularly large orders for deepwater
reservoir characterization projects, can significantly impact our operating results and cash flow for any quarter,
and results of operations for any one quarter may not be indicative of results of operations for future quarters.
These periodic fluctuations in our operating results could adversely affect our stock price.

We Have a Relatively Small Public Float, and Our Stock Price May Be Volatile

We have approximately 4.3 million shares outstanding held by non-affiliates. This small float results in a
relatively illiquid market for our common stock. Our daily trading volume for the year ended September 30, 2006
averaged approximately 42,000 shares, which is relatively small, though higher than in prior years due to the sale
by OYO Corporation, through OYO Corporation U.S.A., of 1,700,000 shares of our common stock during fiscal
years 2006 and 2005. Our small float and daily trading volumes have in the past caused, and may in the future
result in, significant volatility in our stock price.

Our Credit Risk Could Increase If Our Customers Face Difficult Economic Circumstances

We believe that our allowances for bad debts are adequate in light of known circumstances. However, we
cannot assure you that additional amounts attributable to uncollectible receivables and bad debt write-offs will
not have a material adverse effect on our future results of operations. Many of our seismic contractor customers
are not well capitalized and as a result cannot always pay our invoices when due. We have in the past incurred
write-offs in our accounts receivable due to customer credit problems. We have found it necessary from time to
time to extend trade credit, including on promissory notes, to long-term customers and others where some risks
of non-payment exist. Although industry conditions have improved, some of our customers continue to
experience liquidity difficulties, which increase those credit risks. An increase in the level of bad debts and any
deterioration in our credit risk could adversely affect the price of our stock.

Our Industry Is Characterized By Rapid Technological Development and Product Obsolescence

Our instruments and equipment

in both of our business segments are constantly undergoing rapid

technological improvement. Our future success depends on our ability to continue to:

•

•

improve our existing product lines,

address the increasingly sophisticated needs of our customers,

• maintain a reputation for technological leadership,

• maintain market acceptance of our products,

9

•

•

•

anticipate changes in technology and industry standards,

respond to technological developments on a timely basis, and

develop new markets for our products and capabilities.

Current competitors or new market entrants may develop new technologies, products or standards that could
render our products obsolete. We cannot assure you that we will be successful in developing and marketing, on a
timely and cost effective basis, product enhancements or new products that
respond to technological
developments, that are accepted in the marketplace or that comply with new industry standards.

We Operate in Highly Competitive Markets

The markets for most of our products are highly competitive. Many of our existing and potential
competitors have substantially greater marketing, financial and technical resources than we do. Additionally, at
least two competitors in our seismic business segment currently offer a broader range of instruments and
equipment for sale than we do and market this equipment as “packaged” data acquisition systems. We do not
currently offer for sale such a complete “packaged” data acquisition system. Further, certain of our competitors
offer financing arrangements to customers on terms that we may not be able to match. In addition, new
competitors may enter the market and competition could intensify.

As to our thermal solutions products, we compete with other printing solutions, including inkjet and laser

printing technologies, many of which are provided by large companies with significant resources.

We cannot assure you that sales of our products will continue at current volumes or prices if current
competitors or new market entrants introduce new products with better features, performance, price or other
characteristics than our products. Competitive pressures or other factors also may result in significant price
competition that could have a material adverse effect on our results of operations.

We Have a Limited Market for Our Products

In our seismic business segment, we market our traditional products to contractors and large, independent
and government-owned oil and gas companies. We estimate that, based on published industry sources, fewer than
30 seismic contracting companies are currently operating worldwide (excluding those operating in Russia and the
former Soviet Union, India, the People’s Republic of China and certain Eastern European countries, where
seismic data acquisition activity is difficult to verify). We estimate that fewer than 20 seismic contractors are
engaged in marine seismic exploration. Due to these market factors, a relatively small number of customers,
some of whom are experiencing financial difficulties, have accounted for most of our sales. From time to time
these seismic contractors have sought to vertically integrate and acquire our competitors, which has influenced
their supplier decisions before and after such transactions. The loss of a small number of these customers could
materially and adversely impact sales of our seismic products.

We Cannot Be Certain of the Effectiveness of Patent Protection

We hold and from time to time apply for certain patents relating to some of our seismic data acquisition and
other products. We also own several patents which relate to the development of dry thermal film. We cannot
assure you that our patents will prove enforceable or free of challenge, that any patents will be issued for which
we have applied or that competitors will not develop functionally similar technology outside the protection of
any patents we have or may obtain.

Our Foreign Subsidiaries and Foreign Marketing Efforts Face Additional Risks and Difficulties

Net sales outside the United States accounted for approximately 64.6% of our net sales during fiscal year
2006 and are again expected to represent a substantial portion of our net sales for fiscal year 2007 and subsequent

10

years. Substantially all of our sales from the United States are made in U.S. dollars, though from time to time we
make sales in foreign currencies. As a result, we may be subject to foreign currency fluctuations on our sales. In
addition, net assets reflected on the balance sheets of our Russian, Canadian and United Kingdom subsidiaries
are booked in foreign currencies and are subject to currency fluctuations. Consequently, significant foreign
currency fluctuations could adversely impact our results of operations.

Foreign sales are subject to special risks inherent in doing business outside of the U.S., including the risk of
war, terrorist activities, civil disturbances, embargo and government activities and foreign attitudes about
conducting business activities with the U.S., all of which may disrupt markets. A portion of our manufacturing is
conducted through our subsidiary OYO-GEO Impulse, which is based in Ufa, Bashkortostan, Russia. Our
business could be directly affected by political and economic conditions in Bashkortostan and in Russia
generally. Boycotts, protests, governmental sanctions and other actions in the region could adversely affect our
ability to operate profitably. The risk of doing business in Russia and other economically or politically volatile
areas could adversely affect our operations and earnings. Foreign sales are also generally subject to the risk of
compliance with additional laws, including tariff regulations and import and export restrictions. Sales in certain
foreign countries require prior United States government approval in the form of an export license. We cannot
assure you that we will not experience difficulties in connection with future foreign sales. Also due to foreign
laws and restrictions, should we experience substantial growth in certain foreign markets, for example in Russia,
we may not be able to transfer cash balances to the United States to assist with debt servicing or other
obligations.

We Rely on a Key Supplier for a Significant Portion of Our Dry Thermal Film

While we currently manufacture dry thermal film, we also purchase a large quantity of dry thermal film
from a distributor. Except for the film produced by us and sold to us by this distributor, we know of no other
source for dry thermal film that performs well in our thermal imaging equipment.

If we are unable to economically manufacture dry thermal film internally or our distributor were to
discontinue supplying dry thermal film or were unable to supply dry thermal film in sufficient quantities to meet
our requirements, our ability to compete in the thermal imaging marketplace could be impaired, which could
adversely affect our financial performance.

We Have Been Subject to Control by a Principal Stockholder

In August 2005, our single largest stockholder, OYO Corporation, a Japanese corporation, through its
wholly owned subsidiary, OYO Corporation U.S.A., sold 1,400,000 shares of our common stock in a secondary
offering. During fiscal year 2006, pursuant to a privately negotiated transaction, OYO Corporation U.S.A sold
300,000 shares to a former director who in turn sold the shares to non-affiliates. At September 30, 2006, OYO
Corporation owned indirectly in the aggregate approximately 20.1% of our common stock. Accordingly, OYO
Corporation, through its wholly owned subsidiary OYO Corporation U.S.A., is able to exercise substantial
influence over our management, operations and affairs. In addition, we currently have, and may continue to have,
a variety of contractual relationships with OYO Corporation and its affiliates. These relationships could further
enable OYO Corporation to indirectly exert substantial influence on our operations.

Our Success Depends Upon a Limited Number of Key Personnel

Our success depends on attracting and retaining highly skilled professionals. A number of our employees
are highly skilled engineers and other professionals. In addition, our success depends to a significant extent upon
the abilities and efforts of the members of our senior management. If we fail to continue to attract and retain such
professionals, our ability to compete in the industry could be adversely affected.

A General Downturn in the Economy in Future Periods May Adversely Affect Our Business

A general downturn in the economy in future periods could adversely affect our business in ways that we
cannot predict. Any economic downturn may adversely affect the demand for oil and gas generally or cause
volatility in oil and gas commodity prices and, therefore, adversely affect the demand for our services to the oil
and gas industry and related service and equipment. It could also adversely affect the demand for consumer
products, which could in turn adversely affect our thermal solutions business. To the extent these factors
adversely affect other seismic companies in the industry, there could be an oversupply of products and services
and downward pressure on pricing for seismic products and services, which could adversely affect us.

Sarbanes-Oxley Act of 2002

In response to several high profile cases of accounting irregularities, the Sarbanes-Oxley Act of 2002, or the
“Act,” was enacted into law on July 30, 2002. Under current legislation, we are required to comply with the
annual requirements of Section 404 of the Act with respect to our internal controls over financial reporting
effective for our fiscal year ended September 30, 2006. The Act, and rules promulgated thereunder, as well as
NASDAQ listing standards addressing corporate governance issues, endeavor to provide greater accountability
and promote investor confidence by imposing specific corporate governance requirements, by requiring more
stringent controls and certifications by corporate management and by ultimately imposing new auditor
attestations. The Act and NASDAQ rules affect how audit committees, corporate management and auditors of
publicly traded companies carry out their respective responsibilities and interact with each other and mandate
composition of audit committees by independent directors. The Act has resulted in higher expenses for publicly
traded companies, including us, as a result of higher audit and review fees, higher legal fees, higher director fees
and higher internal costs to document, test and potentially remediate internal control deficiencies. The Act,
together with the financial scandals and difficult economic environment of recent years, has also led to
substantially increased premiums for director and officer liability insurance. These increased expenses affect
smaller public companies, like us, disproportionately from their effects on companies with larger revenue and
operating income bases with which to absorb such increased costs.

With respect to the internal controls requirement flowing from the Act, we have devoted substantial efforts
and incurred significant expenses in fiscal years 2005 and 2006 in documenting, testing and remediating potential
deficiencies in our internal controls system. We have added internal resources and hired outside experts to help
us with respect to these matters. We expect to incur substantial expenses in the future to maintain and audit our
internal control documentation and procedures.

We believe that our facilities are adequate for our current and immediately projected needs.

(1) This property is located at 7007 Pinemont Drive in Houston, Texas (the “Pinemont facility”). It was
purchased in September 2003 for the purpose of consolidating into one location all manufacturing,

12

engineering, selling, marketing and administrative activities for both the seismic and thermal solution
segment of our company in the United States. The Pinemont facility also serves as our company
headquarters. Due to capacity constraints and growth expectations, we are adding 130,000 sq. ft. of
manufacturing space and 40,000 sq. ft. of office space. We expect to begin utilizing this additional space in
the second fiscal quarter of fiscal year 2007.

(2) This property, located at 7334 N. Gessner in Houston, Texas (the “Gessner facility”), previously contained a
manufacturing operation and certain support functions. We completed the relocation of these operations to
the Pinemont facility in February 2004. We continue to utilize portions of the Gessner facility for storage
and overflow manufacturing and assembly operations which cannot be accommodated at our Pinemont
facility due to capacity constraints. In February 2006, we entered into a seven-year lease with a tenant
whereby the tenant agreed to lease portions of the building until March 2008, at which time the tenant will
occupy the entire Gessner facility.

(3) This property served as a location for manufacturing operations until October 2002, at which time these
operations were relocated to the new 120,000 square foot building in Ufa noted above. This building is
currently being used as a storage facility. We are seeking to sell this facility.

Item 3. Legal Proceedings

From time to time we are a party to what we believe is routine litigation and proceedings that may be
considered as part of the ordinary course of our business. We are not aware of any current or pending litigation or
proceedings that could have a material adverse effect on our results of operations, cash flows or financial
condition, although we continue to monitor developments in the bankruptcy proceeding by our Former Primary
Film Supplier and its existing claim against us as is described in the section entitled “Business—Thermal
Solutions Products” contained in this Report on Form 10-K.

Item 4. Submission of Matters to Vote of Security Holders

Since our initial public offering in 1997, we have not paid dividends, and we do not intend to pay cash
dividends on our common stock in the foreseeable future. We presently intend to retain our earnings for use in
our business, with any future decision to pay cash dividends dependent upon our growth, profitability, financial
condition and other factors our Board of Directors may deem relevant. Our existing credit agreement also has
covenants which materially limit our ability to pay dividends. For a discussion of our credit agreement, see the
section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operation –
Liquidity and Capital Resources” contained in this Report on Form 10-K.

We did not sell any securities in fiscal years 2005, 2004 or 2003 that were not registered under the
Securities Act of 1933, as amended (the “Securities Act”), except as has previously been disclosed on our
Quarterly Report on Form 10-Q for the quarter ended December 31, 2004 and on our Quarterly Report on Form
10-Q for the quarter ended March 31, 2005. As we disclosed in those reports, an error was discovered as to the
registration under the Securities Act of securities offered under our 1999 Broad-Based Option Plan. Before the
error was discovered and rectified, we issued a total of 700 shares of common stock upon the exercise of options
granted under the Broad-Based Plan for an aggregate consideration of approximately $8,000 without registration
and without exemption from registration under the Act, as follows:

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is management’s discussion and analysis of the major elements of our consolidated financial
statements. You should read this discussion and analysis together with our consolidated financial statements,
including the accompanying notes, and other detailed information appearing elsewhere in this Form 10-K, included
under the heading “Risk Factors”. The discussion of our financial condition and results of operations includes
various forward-looking statements about our markets, the demand for our products and services and our future
plans and results. These statements are based on assumptions that we consider to be reasonable, but that could prove
to be incorrect. For more information regarding our assumptions, you should refer to the section entitled
“—Forward-Looking Statements and Assumptions” contained in this Item 7 in this Report on Form 10-K.

Background

We design and manufacture instruments and equipment used in the acquisition and processing of seismic
data as well as in the characterization and monitoring of producing oil and gas reservoirs. We have been in the
seismic instrument and equipment business since 1980 and market our products primarily to the oil and gas
industry. We also design, manufacture and distribute thermal imaging equipment and dry thermal film products
targeted at the screen print, point of sale, signage and textile market sectors. We have been manufacturing
thermal imaging products in what is called our Thermal Solutions segment since 1995. For a more detailed
discussion of our business segments and products, see the information under the heading “Business” in this
Report on Form 10-K.

Overview

Fiscal Year 2006 Compared to Fiscal Year 2005

Consolidated net sales for the year ended September 30, 2006 increased $30.9 million, or 42.4%, from fiscal
year 2005. The increase in sales reflects strong demand from customers for our seismic exploration and seismic
reservoir products as exploration activities increased due to higher oil and gas commodity prices.

Consolidated gross profits for the year ended September 30, 2006 increased by $14.4 million, or 65.7%,
from fiscal year 2005. In addition, consolidated gross profit margins, as a percentage of sales, increased from
30.0% in fiscal year 2005 to 35.0% in fiscal year 2006. The increase in gross profits resulted primarily from
significantly increased sales of our seismic reservoir products and marine-based seismic products, which have
higher gross profit margins.

Consolidated operating expenses for the year ended September 30, 2006 increased $3.3 million, or 18.0%,
from fiscal year 2005. The increase in operating expenses primarily resulted from increased incentive
compensation expense, research and development expenses, stock-based compensation expenses, increased
auditing and consulting expenses related to Sarbanes-Oxley readiness and other cost increases due to the increase
in net sales.

The U.S. statutory rate applicable to us for the periods reported was 34.0%; however, our effective tax rate
was 31.4% and 24.1%, for the years ended September 30, 2006 and 2005, respectively. Each of these effective
tax rates primarily reflects anticipated U.S. tax benefits related to foreign export sales and a lower statutory tax
rate in Russia. In fiscal year 2006, these tax benefits were partially offset by a net charge of $0.1 million relating
to the resolution of an Internal Revenue Service audit of our fiscal year 2003 tax return and from the resolution of
prior year tax contingencies. As a result of U.S. tax legislation that phases out a special deduction allowed to U.S.
export manufacturers, we expect our effective tax rate to increase in fiscal year 2007 and subsequent years.

18

Fiscal Year 2005 Compared to Fiscal Year 2004

Consolidated net sales for the year ended September 30, 2005 increased $9.3 million, or 14.6%, from fiscal
year 2004. The increase in sales reflected strong demand from customers for our seismic equipment as
exploration activities increased due to higher oil and gas commodity prices. Sales for fiscal year 2004 included a
performance bonus of $3.6 million resulting from the successful installation and performance of a large seismic
data acquisition system developed for permanent installation in the Valhall field in the North Sea (the “Valhall
System”) for BP p.l.c. (“BP”) in fiscal years 2002 and 2003.

Consolidated gross profits for the year ended September 30, 2005 decreased by $0.9 million, or 3.8%, from
fiscal year 2004. Excluding a $3.6 million performance bonus received in fiscal year 2004 from the sale of the
Valhall System, fiscal year 2005 consolidated gross profits increased by $2.8 million, or 14.5%. This increase in
gross profits resulted primarily from increased sales of our seismic exploration products for the reasons discussed
above. Consolidated gross profit margins, as a percentage of sales, declined from 35.8% in fiscal year 2004 to
30.0% in fiscal year 2005. Excluding the $3.6 million performance bonus referred to above, consolidated gross
profit margins were 31.9% in fiscal year 2004. The decline in gross profit margins was partially due to a greater
mix of seismic exploration products in fiscal year 2005 as compared to fiscal year 2004, which, sales generally
yield lower gross profit margins. In addition, in fiscal year 2005 we continued to experience some inefficiencies
in our manufacturing operations attributable to rapid growth, the need to upgrade some of our manufacturing
systems and personnel stress.

Consolidated operating expenses for the year ended September 30, 2005 increased $1.6 million, or 9.4%,
from fiscal year 2004. The increase in operating expenses primarily resulted from (i) increased bad debt expense,
(ii) Sarbanes-Oxley readiness costs, (iii) consulting expenses related to upgrading and improving our enterprise
software system, and (iv) costs to relocate employees from Japan to Houston in connection with our acquisition
of assets from Graphtec described under the heading “Business—Thermal Solutions Products”. These operating
expense increases were partially offset by lower incentive compensation expenses in fiscal year 2005.

The U.S. statutory rate applicable to us for fiscal year 2005 was 34.0%; however, our effective tax rate for
the year ended September 30, 2005 was 24.1%. The fiscal year 2005 effective tax rate primarily reflected
anticipated U.S. tax benefits related to extraterritorial income deductions applicable to foreign export sales and
lower tax rates in certain foreign jurisdictions. Our effective tax rate for fiscal year 2004 was (0.8)%. We realized
several significant tax benefits in fiscal year 2004, including (i) tax credits and a special tax deduction allowed to
U.S. export manufacturers totaling $0.9 million, (ii) the reversal of an $0.8 million deferred tax valuation
allowance due to the realization of deferred tax assets, and (iii) a $0.4 million benefit resulting from the taxing
rates in certain foreign taxing jurisdictions being lower than the U.S. statutory tax rate.

Segment Results of Operations

Seismic Products

Fiscal Year 2006 Compared to Fiscal Year 2005

Net Sales. Sales of our seismic products for fiscal year 2006 increased $29.1 million, or 49.0%, from fiscal
year 2005. The significant increase in sales primarily resulted from increased sales of reservoir characterization
systems and marine-based exploration products. These sales increases resulted from increasing acceptance by
customers of our reservoir-focused technologies, and from increasing oil and gas exploration activities causing
demand for our marine-based exploration products. Our reservoir characterization products and marine-based
seismic products generally yield higher gross margins than do our other seismic exploration products. To a lesser
extent, our emerging products, including offshore cables, industrial cables and industrial sensors also generated
higher revenues during fiscal year 2006.

Operating Income. Operating income from sales of our seismic products for fiscal year 2006 increased
$12.2 million, or 121.5%, from fiscal year 2005. Our operating income increased in fiscal year 2006 due to

19

increased sales and from a greater mix of high profit margin product sales including reservoir characterization
products and marine-based exploration products.

Fiscal Year 2005 Compared to Fiscal Year 2004

Net Sales. Sales of our seismic products for fiscal year 2005 increased $8.8 million, or 17.3%, from fiscal
year 2004. The significant increase in sales primarily resulted from increased sales to our seismic exploration
customers, including customers in Canada and Russia. Due to the effects of Hurricane Rita which impacted the
Houston area in late September 2005, we were unable to deliver a $1.1 million seismic borehole system to a
customer in fiscal year 2005. This system was subsequently delivered to a customer in October 2005. A total of
five days of production was lost as a result of Hurricane Rita. Sales for fiscal year 2004 include a performance
bonus of $3.6 million from the successful installation and performance of the Valhall System in fiscal years 2002
and 2003.

Operating Income. Operating income from sales of our seismic products for the fiscal year 2005 decreased
$0.8 million, or 7.3%, from fiscal year 2004. Excluding the $3.6 million performance bonus payment received in
fiscal year 2004 and $1.1 million of associated incentive compensation expense, operating income for fiscal year
2005 increased $1.8 million, or 21.2%, due to higher sales of seismic exploration products.

Thermal Solutions Products

Fiscal Year 2006 Compared to Fiscal Year 2005

Net Sales. Sales of our thermal solutions products for fiscal year 2006 increased $1.8 million, or 13.1%,
from fiscal year 2005. We believe this increase in sales results from a broader acceptance of our thermal imaging
products in the markets we serve.

Operating Income. Our operating income from our thermal solutions products for fiscal year 2006 increased
$0.2 million, or 51.6%, from fiscal year 2005. Such increase in operating income is the result of increased sales
and manufacturing process improvements.

Fiscal Year 2005 Compared to Fiscal Year 2004

Net Sales. Sales of our thermal solutions products for fiscal year 2005 increased $0.4 million, or 3.3%, from
fiscal year 2004. While sales did not change significantly in any particular product line from the prior fiscal year,
sales of printheads to new customers increased due to the purchase of assets from Graphtec in September 2004
described under the heading “Business—Thermal Solutions Products”. During fiscal year 2005, we experienced
shortages of certain component parts which delayed the shipment of certain thermal solutions products. Such
shortages were isolated to certain suppliers and were temporary.

Operating Income. Our operating income from our thermal solutions products for fiscal year 2005 decreased
$0.8 million, or 67.5%, from fiscal year 2004. Such decrease was generally the result of foreign administrative
office expenses, idle production costs and start-up expenses, all associated with the transition from Japan to
Houston of the thermal printhead production assets purchased from Graphtec and related manufacturing
inefficiencies.

Recent Acquisitions

OYO-GEO Impulse International, LLC

At September 30, 2005, we owned a 97% interest in OYO-GEO Impulse, our Russian subsidiary. In October
2005, we purchased for $0.1 million the remaining 3% ownership interest in this entity from the minority
shareholder. OYO-GEO Impulse is now a wholly-owned subsidiary of the Company. OYO-GEO Impulse

20

manufactures international-standard geophone sensors and related seismic products for the Russian and
international seismic marketplaces.

Form 10-K.

Facilities Expansion

We are currently running at or near full capacity in portions of our Pinemont facility. As a result, we are in
the process of expanding the manufacturing space at our Pinemont facility to approximately double its current
size and adding the appropriate manufacturing machinery and equipment to meet expected future demand. We
estimate the facility expansion and machinery and equipment additions will cost approximately $12.0 million and
will be completed by the end of the second quarter of our 2007 fiscal year. The facility expansion is expected to
be financed with a long-term loan secured by a mortgage on our Pinemont facility, and any machinery and
equipment is expected to be financed from our internal cash flows and/or from borrowings under our Credit
Agreement, discussed below under the heading “—Liquidity and Capital Resources”.

In February 2006, we entered into a seven-year lease with a tenant whereby the tenant agreed to lease
portions of our Gessner facility until March 2008, at which time the tenant will occupy the entire Gessner
facility. The tenant began occupying the Gessner facility in August 2006, and we earned $37,000 of rental
income in fiscal year 2006. We continue to utilize portions of the Gessner facility for storage and overflow
manufacturing and assembly operations which cannot be accommodated at our Pinemont facility due to capacity
constraints. It is our expectation to transfer these storage and assembly operations to our Pinemont facility prior
to March 2008, following the completion of our expansion of the Pinemont facility.

Liquidity and Capital Resources

At September 30, 2006, we had $2.1 million in cash and cash equivalents. For fiscal year 2006, we
generated approximately $5.4 million of cash in operating activities. The cash generated in operating activities
primarily resulted from net income of $9.8 million, which includes non-cash charges of $6.1 million for deferred
taxes, stock-based compensation, depreciation and amortization. Other sources of cash from operating activities
and changes in our working capital accounts included (i) $9.0 million of deferred revenue resulting from
advanced payments received from customers purchasing our seismic reservoir products, (ii) $4.8 million in
accrued expenses primarily due to increased accrual for unpaid incentive compensation, and (iii) $2.2 million in
accounts payable primarily resulting from increased inventories. These sources of cash were partially offset by a
$16.2 million increase in inventories due to increased orders from our seismic customers, and an $11.2 million
increase in accounts and notes receivable resulting from increased sales activity.

For fiscal year ended September 30, 2006, we used approximately $4.6 million of cash in investing
activities, including $4.8 million for capital expenditures, which was partially offset by $0.3 million of cash
proceeds we received from the sale of surplus land. We estimate that our total capital expenditures in fiscal year
2007 will be approximately $14.5 million, which includes expenditures to expand our Pinemont facility and to
acquire new machinery and equipment. We expect to fund the facility expansion through a long-term loan
secured by a mortgage on our Pinemont facility, and any machinery and equipment will be financed from our
internal cash flow and/or from borrowings under the Credit Agreement.

For fiscal year 2006, we used approximately $1.0 million of cash in the financing activities of our
operations, which we obtained from net repayment of borrowings under the Credit Agreement in the amount of
$3.3 million. Such use of cash was partially offset by $1.4 million of cash received from the exercise of stock
options by employees and a director, and a $0.9 million tax benefit related to such stock option exercises.

21

At September 30, 2005, we had $1.8 million in cash and cash equivalents. For fiscal year 2005, we used
approximately $1.6 million of cash in operating activities. The cash used in operating activities was primarily
used in connection with an increase in inventories of $7.8 million due to increased orders from customers and
decreased cash resulting from $3.4 million less of net income in fiscal year 2005 than fiscal year 2004.

For fiscal year ended September 30, 2005, we used approximately $4.9 million of cash in investing
activities. We received $1.3 million of cash proceeds from the sale of a facility in Stafford, Texas. We used $6.2
million of cash for capital expenditures, including approximately $1.4 million which was paid to Graphtec on
October 1, 2004 for its printhead production assets and $1.0 million which was used for the construction of a
cleanroom at our Pinemont facility for thermal printhead production as a result of our acquisition of the thermal
printhead production assets from Graphtec as is described under the heading “Business—Thermal Solutions
Products”.

For fiscal year 2005, we generated approximately $4.8 million of cash in financing activities which we
obtained from borrowings under the Credit Agreement. This amount includes $0.7 million as a result of the
repayment of a mortgage upon the sale of our Stafford facility.

At September 30, 2004, we had $3.1 million in cash and cash equivalents. For fiscal year 2004, we
generated approximately $8.4 million of cash from operating activities. The cash generated by operating
activities was derived from a combination of our net income of $6.0 million and $5.0 million of non-cash
depreciation and amortization charges. This cash flow was partially offset by a $1.0 million non-cash deferred
tax benefit. Other operating cash flows included increases in accrued expenses in the amount of $1.9 million
primarily reflecting fiscal year 2004 accrued incentive compensation expenses. Income taxes payable in fiscal
year 2004 increased by $0.6 million, reflecting taxes owed on the profits of our foreign subsidiaries. Such
sources of cash were offset by a $2.7 million increase in accounts and notes receivable resulting from increased
sales, and a $2.5 million increase in inventories also as a result of increased sales.

For fiscal year 2004, we used approximately $1.3 million of cash in investing activities. We received $1.2
million of cash proceeds from the sale of a surplus building and a vacant parcel of land as part of our
consolidation and reorganization of facilities. We used $2.5 million of cash for capital expenditures of which
approximately $1.4 million represented improvements to our Pinemont facility.

For year 2004, we used approximately $4.9 million of cash from financing activities, primarily for the

repayment of borrowings under our prior credit facility.

On November 22, 2004, several of our subsidiaries entered into a credit agreement (the “Credit Agreement”)
with a bank. Under the Credit Agreement, as amended on September 19, 2005 and June 16, 2006, our borrower
subsidiaries can borrow up to $20.0 million principally secured by their accounts, inventories and equipment.
The Credit Agreement expires on November 21, 2007. The Credit Agreement limits the incurrence of additional
indebtedness, requires the maintenance of certain financial ratios, restricts our and our borrower subsidiaries’
ability to pay dividends and contains other covenants customary in agreements of this type. We believe that the
ratio of total liabilities to tangible net worth and the asset coverage ratio could prove to be the most restrictive.
The interest rate for borrowings under the Credit Agreement is, at our borrower subsidiaries’ option, a discounted
prime rate or a LIBOR based rate. At September 30, 2006, there were borrowings of $2.9 million under the
Credit Agreement, $0.3 million of standby letters of credit were outstanding and additional available borrowings
of $16.8 million.

We believe that the combination of existing cash reserves, cash flows from operations and borrowing
availability under the Credit Agreement should provide us sufficient capital resources and liquidity to fund our
planned operations through fiscal year 2007. However, there can be no assurance that such sources of capital will
be sufficient to support our capital requirements in the long-term, and we may be required to issue additional
debt or equity securities in the future to meet our capital requirements. There can be no assurance we would be
able to issue additional equity or debt securities in the future on terms that are acceptable to us or at all.

Off-Balance Sheet Arrangements

We do not have any obligations which meet the definition of an off-balance sheet arrangement and which
have or are reasonably likely to have a current or future effect on our financial statements or the items contained
therein that are material to investors.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the
United States requires the use of estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. We consider many factors in selecting appropriate operational and financial
accounting policies and controls, and in developing the estimates and assumptions that are used in the
preparation of these financial statements. We continually evaluate our estimates, including those related to bad
debt reserves, inventory obsolescence reserves, self-insurance reserves, product warranty reserves, intangible
assets, stock-based compensation and deferred income tax assets. We base our estimates on historical experience
and various other factors that are believed to be reasonable under the circumstances. Actual results may differ
from these estimates under different conditions or assumptions.

Goodwill represents the excess of the purchase price of purchased businesses over the estimated fair value
of the acquired business’ net assets. Under the Statement of Financial Accounting Standards, or “SFAS”, 142
(“SFAS 142”), goodwill and intangible assets with indefinite lives are no longer amortized but are reviewed
periodically for impairment. Intangible assets that are not deemed to have indefinite lives will continue to be
amortized over their useful lives; however, no maximum life applies. In accordance with the provisions of SFAS
142, we no longer record goodwill amortization expense. We review the carrying value of goodwill and other
long-lived assets to determine whether there has been an impairment since the date of the relevant acquisition.
We have elected to make September 30 the annual impairment assessment date and will perform additional
impairment tests if a change in circumstances occurs that would more likely than not reduce the fair value of
long-lived assets below their carrying amount. The assessment is performed in two steps: step one is to test for
potential impairment and if potential losses are identified, step two is to measure the impairment loss. We
performed step one at September 30, 2006 and found that there were no impairments at that time; thus, step two
was not necessary.

23

We primarily derive revenue from the sale, and short-term rental under operating leases, of seismic
instruments and equipment and thermal solutions products. We generally recognize sales revenues when our
products are shipped and title and risk of loss have passed to the customer. We recognize rental revenues as
earned over the rental period. Rentals of our equipment generally range from daily rentals to rental periods of up
to six months or longer. Except for certain of our reservoir characterization products, our products are generally
sold without any customer acceptance provisions and our standard terms of sale do not allow customers to return
products for credit. In instances where there is a significant performance test, we do not recognize the revenue
attributable to the product as to which the performance test applies until the performance test is satisfied.
Collection of this revenue may occur at various stages of production or after delivery of the product, and is not
refundable to the customer.

Most of our products do not require installation assistance or sophisticated instruction. We offer a standard
product warranty obligating us to repair or replace equipment with manufacturing defects. We maintain a reserve
for future warranty costs based on historical experience or, in the absence of historical experience, management
estimates. We record a write-down of inventory when the cost basis of any item (including any estimated future
costs to complete the manufacturing process) exceeds its net realizable value.

We recognize revenue when all of the following criteria are met:

•

Persuasive evidence of an arrangement exists. We operate under a purchase order/contract system for
goods sold to customers, and under rental/lease agreements for equipment rentals. These documents
evidence that an arrangement exists.

• Delivery has occurred or services have been rendered. For product sales, we do not recognize revenues
until delivery has occurred or performance measures are met. For rental revenue, we recognize revenue
when earned.

•

The seller’s price to the buyer is fixed or determinable. Sales prices are defined in writing in a
customer’s purchase order, purchase contract or equipment rental agreement.

• Collectibility is reasonably assured. We evaluate customer credit to ensure collectibility is reasonably

assured.

Occasionally our seismic customers are not able to take immediate delivery of products which were
specifically manufactured to the customer’s specifications. These occasions generally occur when our customers
face logistical issues such as project delays or with their seismic crew deployment. In these instances, our
customers have asked us to hold the equipment for a short period of time until they can take physical delivery of
the product (referred to as “bill and hold” arrangements). We consider the following criteria for recognizing
revenue when delivery has not occurred:

• Whether the risks of ownership have passed to the customer,

• Whether we have obtained a fixed commitment to purchase the goods in written documentation from the

customer,

• Whether the customer requested that the transaction be on a bill and hold basis and we received that

request in writing,

• Whether there is a fixed schedule for delivery of the product,

• Whether we have any specific performance obligations such that the earning process is not complete,

• Whether the equipment is segregated from our other inventory and are not subject to being used to fill

other orders, and

• Whether the equipment is complete and ready for shipment.

We do not modify our normal billing and credit terms for these types of sales. As of September 30, 2006, we

had no sales under bill and hold arrangements.

Recent Accounting Pronouncements

In November 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 151 “Inventory
Costs” (“SFAS 151”). This statement amends the guidance in ARB No. 43, Chapter 4, “Inventory Pricing,” to
clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material
(spoilage). SFAS 151 requires that those items be recognized as current-period charges. In addition, this
statement requires the allocation of fixed production overhead to costs of conversion be based upon the normal
capacity of the production facilities. We adopted the provisions of SFAS 151 as of October 1, 2005. The adoption
of SFAS 151 did not have a material effect on our consolidated financial statements.

In December 2004, the FASB issued SFAS No. 123R, “Share-Based Payment” (“SFAS 123R”), which
requires companies to measure and recognize compensation expense for all stock-based payments at fair value.
SFAS 123R is effective for all interim periods beginning after June 15, 2005. We adopted the provisions of
SFAS 123R at the beginning of our 2006 fiscal year and recorded stock-based compensation expense of $0.6
million for fiscal year 2006.

On December 16, 2004,

the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets, an
amendment of APB Opinion No. 29” (“SFAS No. 153”). SFAS No. 153 replaces the exception from fair value
measurement in APB Opinion No. 29 for nonmonetary exchanges of similar productive assets with a general
exception from fair value measurement for exchanges of nonmonetary assets that do not have commercial
substance. A nonmonetary exchange has commercial substance if the future cash flows of the entity are expected
to change significantly as a result of the exchange. We adopted the provisions of SFAS No. 153 as of October 1,
2005. The adoption of SFAS No. 153 did not have a material effect on our consolidated financial statements.

In March 2005, the FASB issued Interpretation No. 47 (“FIN 47”), Accounting for Conditional Asset
Retirement Obligations—an interpretation of FASB Statement No. 143, to clarify the term “conditional asset
retirement obligation”, which refers to legal obligations for which companies must perform asset retirement
activity for which the timing and/or method of settlement are conditional upon future events that may or may not
be within the control of the entity. However, the obligation to perform the asset retirement is unconditional,
despite the uncertainty that exists surrounding the timing and method of settlement. Uncertainty about the timing
and method of settlement for a conditional asset retirement obligation (“ARO”) should be considered in
estimating the ARO when sufficient information exists. FIN 47 clarifies when sufficient information exists to
reasonably estimate the fair value of an ARO. This interpretation is effective for our 2006 fiscal year. Our
adoption of FIN 47 did not have a material effect on our consolidated financial statements.

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections—a replacement
of APB Opinion No. 20 and FASB Statement No. 3” (“SFAS No. 154”). SFAS No. 154 requires retrospective
application to prior periods’ financial statements for changes in accounting principle, unless it is impracticable to
determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also requires
that retrospective application of a change in accounting principle be limited to the direct effects of the change.
Indirect effects of a change in accounting principle should be recognized in the period of the accounting change.
SFAS No. 154 also requires that a change in depreciation, amortization, or depletion method for long-lived
non-financial assets be accounted for as a change in accounting estimate affected by a change in accounting
principle. SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years
beginning after December 15, 2005. Our adoption of SFAS No. 154 is not expected to have a material effect on
our consolidated financial statements.

In June 2006, the FASB issued Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income
Taxes—an interpretation of FASB Statement No. 109, to clarify certain aspects of accounting for uncertain tax
position, including issues related to the recognition and measurement of those tax positions. This interpretation is
effective for fiscal years beginning after December 15, 2006, and therefore will apply beginning with our 2008
fiscal year. We are in the process of evaluating the impact of this interpretation.

25

In September 2006, the FASB issued SFAS No. 157 (“SFAS 157”), “Fair Value Measurements.” Among
other requirements, SFAS 157 defines fair value and establishes a framework for measuring fair value and also
expands disclosure about the use of fair value to measure assets and liabilities. SFAS 157 will be effective
beginning with our fiscal year beginning on October 1, 2008. We are evaluating the impact of SFAS 157 on our
financial position and results of operations.

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108,
“Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year
Financial Statements” (“SAB 108”), which provides interpretive guidance on how the effects of the carryover or
reversal of prior year misstatements should be considered in quantifying a current year misstatement. The
guidance is applicable for fiscal years ending after November 15, 2006. We do not believe SAB 108 will have a
material effect on our consolidated financial statements.

Forward-Looking Statements and Assumptions

This Report on Form 10-K and the documents incorporated by reference herein, if any, contain “forward-
looking” statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. You can identify these forward-looking
statements by terminology such as “may”, “will”, “should”, “intend”, “expect”, “plan”, “budget”, “forecast”,
“anticipate”, “believe”, “estimate”, “predict”, “potential”, “continue” or similar words. You should read
statements that contain these words carefully because they discuss our future expectations, contain projections of
our future results of operations or of our financial position or state other forward-looking information. These
forward-looking statements reflect our best judgment about future events and trends based on the information
currently available to us. However, there may be events in the future that we are not able to predict or control.
The factors listed under the caption “Risk Factors”, as well as cautionary language in this Report on Form 10-K,
provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the
expectations we describe in our forward-looking statements. You should be aware that the occurrence of the
events described in these risk factors and elsewhere in this Report on Form 10-K could have a material adverse
effect on our business, results of operations and financial position, and actual events and results of operations
may vary materially from our current expectations.

Management’s Current Outlook and Assumptions

Our estimates as to future results and industry trends, to the extent described in this document, are generally
based on assumptions regarding the future level of seismic exploration activity, seismic reservoir monitoring
projects, demand for offshore cable products and industrial sensors and demand for thermal
imaging
technologies, and in turn, their effect on the demand and pricing of our products and services. Our analysis of the
market and its impact on us is based upon the following assumptions:

• We believe the impact of political conditions and hostilities around the world, including those of the
Middle East, which may have a significant impact on the oil and gas commodity prices, will not cause a
significant decrease in demand for our seismic products for the foreseeable future.

• While demand for our traditional seismic exploration products is cyclical, we believe demand for these
products will continue to be strong through fiscal year 2007 as a result of high oil and gas commodity
prices. However, we expect intense competition and pricing pressures to continue to impact the gross
profit margins we realize on our seismic exploration products.

• We expect revenues from our borehole and deepwater reservoir characterization products to increase
significantly in fiscal year 2007 based upon our existing customer orders and increasing acceptance of
this technology by oil companies to more efficiently manage producing reservoirs.

• Demand for our products used in the thermal solutions industry is expected to increase marginally for

the foreseeable future.

26

• As our offshore cable products and industrial sensors gain market acceptance, we expect demand for

these products to increase.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The following discussion of our exposure to various market risks contains “forward looking statements” that
involve risks and uncertainties. These projected results have been prepared utilizing certain assumptions
considered reasonable in light of information currently available to us. Nevertheless, because of the inherent
unpredictability of foreign currency rates and interest rates, as well as other factors, actual results could differ
materially from those projected in this forward looking information. For a description of our significant
accounting policies associated with these activities, see under the heading “Management’s Discussion and
Analysis of Financial Condition and Results of Operations—Critical Accounting Policies” contained in this
report on Form 10-K.

We do not have any market risk as to market risk sensitive instruments entered into for trading purposes and
have only very limited risk as to arrangements entered into other than for trading purposes. Further, we do not
engage in commodity or commodity derivative instrument purchasing or selling transactions.

Foreign Currency and Operations Risk

Our subsidiary, OYO-GEO Impulse, is located in Russia. Therefore, our financial results may be affected by
factors such as changes in foreign currency exchange rates, weak economic conditions in Russia or changes in
Russia’s political climate. Our consolidated balance sheet at September 30, 2006 reflected approximately $3.4
million of net working capital related to OYO-GEO Impulse. OYO-GEO Impulse both receives its income and
pays its expenses primarily in rubles. To the extent that transactions of OYO-GEO Impulse are settled in rubles, a
devaluation of the ruble versus the U.S. dollar could reduce any contribution from OYO-GEO Impulse to our
consolidated results of operations and total comprehensive income as reported in U.S. dollars. We do not hedge
the market risk with respect to our operations in Russia; therefore, such risk is a general and unpredictable risk of
future disruptions in the valuation of Russian rubles versus U.S. dollars to the extent such disruptions result in
any reduced valuation of OYO-GEO Impulse’s net working capital or future contributions to our consolidated
results of operations. At September 30, 2006, the foreign exchange rate of the U.S. dollar to ruble was 1:26.80. If
the U.S. dollar versus ruble exchange rate were to decline by ten percent our working capital could decline by
$0.3 million.

Foreign Currency Intercompany Accounts and Notes Receivable

From time to time, we provide access to capital to our foreign subsidiaries through U.S. dollar denominated
interest bearing promissory notes. Such funds are generally used by our foreign subsidiaries to purchase capital
assets and for general working capital needs. In addition, we sell products to our foreign subsidiaries in U.S.
dollars on trade credit terms. Because these U.S. dollar denominated intercompany debts are accounted for in the
local currency of our foreign subsidiaries, any appreciation or devaluation of such foreign currencies against the
U.S. dollar will result
to our consolidated statement of operations. At
September 30, 2006, we had outstanding accounts and notes receivable of $1.3 million, $82,000 and $53,000
from our subsidiaries in Russia, Europe, and Canada, respectively. At September 30, 2006, the foreign exchange
rate of the U.S. dollar to ruble was 1:26.80. If the U.S. dollar versus ruble exchange rate were to decline by ten
percent our intercompany notes receivable could decline by $0.1 million. Due to the relatively small amounts of
intercompany receivables due from Europe and Canada changes in the exchange rate would have an immaterial
effect.

in a gain or loss, respectively,

Floating Interest Rate Risk

The Credit Agreement and the real estate mortgage agreement for our Pinemont facility each contains a
floating interest rate. These floating interest rates subject us to the risk of increased interest costs associated with

27

any upward movements in bank market interest rates. Under the Credit Agreement, our borrowing interest rate is
a discounted prime lending rate or a LIBOR based rate, whichever we select. Under the real estate mortgage
agreement, our borrowing rate is a LIBOR based rate plus 159 basis points with a minimum rate of 3.8%. As of
September 30, 2006, we had borrowed $2.9 million under the Credit Agreement at a rate of 6.9% and we had
borrowed $2.7 million under our real estate mortgage agreement at a rate of 6.9%. Due to the amount of
borrowings outstanding under these facilities,
including potential borrowings available under the Credit
Agreement, any increased interest costs associated with movements in market interest rates could be material to
our financial condition, results of operation and/or cash flow. At September 30, 2006, based on our current level
of borrowings, a 1.0% increase in interest rates would increase our interest expense annually by approximately
$56,000.

Item 8. Financial Statements and Supplementary Data

Our consolidated financial statements, including the reports thereon, the notes thereto and supplementary

data begin at page F-1 of this Form 10-K and are incorporated herein by reference.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Our independent public accountant has not resigned, declined to stand for reelection or been dismissed, and
there has been no disagreement related to accounting principles, audit procedures or financial statement
disclosure between us and our independent public accountant, in our last two fiscal years and continues to serve
as our independent public accountant.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining a system of disclosure controls and
procedures that are designed to ensure that information required to be disclosed in our reports filed under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized and
reported within the time periods specified under SEC’s rules and forms, and that such information is accumulated
and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial
Officer (“CFO”). Notwithstanding the foregoing, there can be no assurance that the Company’s disclosure
controls and procedures will detect or uncover all failures of persons within the Company and its consolidated
subsidiaries to report material information otherwise required to be set forth in the Company’s reports.

In connection with the preparation of this Annual Report on Form 10-K, the Company carried out an
evaluation under the supervision and with the participation of the Company’s management, including the CEO
and CFO, as of September 30, 2006 of the effectiveness of the Company’s disclosure controls and procedures, as
such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on that evaluation, the
CEO and CFO concluded that our disclosure controls and procedures are effective in ensuring that all material
information required to be filed in this annual report has been made known to them in a timely fashion.

In our Annual Report on Form 10-K for the fiscal year ended September 30, 2005, we disclosed that a
material weakness existed in our controls over the year-end physical inventory. Specifically, as previously
disclosed, the controls in place to ensure an accurate count and verify the existence of inventory at our Pinemont
facility in Houston, Texas were not properly designed and thus, failed to detect counting errors and other
inaccuracies prior to the posting of the physical inventory adjustments to the general ledger. Following the
discovery of the material weakness, management implemented a number of measures described in our Annual
Report on Form 10-K for the fiscal year ended September 30, 2005 to remedy the weakness. As a result of those
measures, and as stated above, the CEO and CFO have determined that our disclosure controls and procedures
for fiscal year 2006, including our control over the year-end physical inventory, are effective.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial
reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Because of its inherent
limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of
September 30, 2006. In making this assessment, we used the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in Internal Control Integrated Framework. Based on this
assessment, our management concludes that, as of September 30, 2006, our internal control over financial
reporting is effective based on those criteria.

Our management’s assessment of the effectiveness of our internal control over financial reporting as of
September 30, 2006 has been audited by PricewaterhouseCoopers LLP, an independent registered public
accounting firm, as stated in their report which appears herein.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting identified in connection with our
management’s evaluation of such internal control
that occurred during our fourth fiscal quarter ended
September 30, 2006 that has materially affected, or is reasonably likely to materially affect, our internal control
over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders
of OYO Geospace Corporation:

We have completed an integrated audit of OYO Geospace Corporation’s 2006 consolidated financial
statements and of its internal control over financial reporting as of September 30, 2006 and audits of its 2005 and
2004 consolidated financial statements in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements and financial statement schedule

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all
material respects, the financial position of OYO Geospace Corporation and its subsidiaries at September 30, 2006
and September 30, 2005, and the results of their operations and their cash flows for each of the three years in the
period ended September 30, 2006 in conformity with accounting principles generally accepted in the United
States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index
presents fairly, in all material respects, the information set forth therein when read in conjunction with the related
consolidated financial statements. These financial statements and financial statement schedule are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial
statements and financial statement schedule based on our audits. We conducted our audits of these statements in
accordance with the standards of the Public Company Accounting Oversight Board (United States). 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 of financial statements includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which

it accounts for share-based compensation in 2006.

Internal control over financial reporting

Also, in our opinion, management’s assessment, included in Management’s Report on Internal Control Over
Financial Reporting appearing under Item 9A, that the Company maintained effective internal control over
financial reporting as of September 30, 2006 based on criteria established in Internal Control—Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is
fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company
maintained, in all material respects, effective internal control over financial reporting as of September 30, 2006,
based on criteria established in Internal Control—Integrated Framework issued by the COSO. The Company’s
management
is responsible for maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express
opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial
reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance
with the standards of the Public Company Accounting Oversight Board (United States). Those standards require
that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over
financial reporting was maintained in all material respects. An audit of internal control over financial reporting
includes obtaining an understanding of internal control over financial reporting, evaluating management’s
assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such
other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable
basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in

F-2

accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Policies:

The Company

OYO Geospace Corporation (“OYO”) designs and manufactures instruments and equipment used in the
acquisition and processing of seismic data as well as in the characterization and monitoring of producing oil and
gas reservoirs. OYO also manufactures and distributes thermal imaging equipment and dry thermal film products
to a variety of markets including the screenprint, point of sale, signage and textile markets. As of September 30,
2006 OYO Corporation U.S.A. (“OYO USA”) owned approximately 20.1% of OYO’s common stock. OYO
USA is a wholly owned subsidiary of OYO Corporation, a Japanese corporation (“OYO Japan”).

OYO and its subsidiaries are referred to collectively as the “Company”. The significant accounting policies

followed by the Company are summarized below.

Basis of Presentation

The accompanying financial statements present the consolidated financial position, results of operations and
cash flows of the Company in accordance with generally accepted accounting principles. All intercompany
balances and transactions have been eliminated.

Reclassification

Certain amounts previously presented in the consolidated financial statements have been reclassified to

conform to the current year presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the
United States of America requires the use of estimates and assumptions that affect the amounts reported in the
financial statements and accompanying notes. The Company considers many factors in selecting appropriate
operational and financial accounting policies and controls, and in developing the estimates and assumptions that
are used in the preparation of these financial statements. The Company continually evaluates its estimates,
including those related to bad debt reserves, inventory obsolescence reserves, self-insurance reserves, product
warranty reserves, long-lived assets, intangible assets and deferred income tax assets. The Company bases its
estimates on historical experience and various other factors that are believed to be reasonable under the
circumstances. Actual results may differ from these estimates under different conditions or assumptions.

Cash and Cash Equivalents

The Company considers all highly liquid debt securities purchased with an original or remaining maturity at

the time of purchase of three months or less to be cash equivalents.

Concentrations of Credit Risk

The Company maintains its cash in bank deposit accounts that, at times, exceed federally insured limits.
Management of the Company believes that the financial strength of the financial institutions holding such
deposits minimizes the credit risk of such deposits.

The Company sells products to customers throughout the United States and various foreign countries. The
Company’s normal credit terms for trade receivables are 30 days. In certain situations, credit terms may be
extended to 60 days or longer. The Company performs ongoing credit evaluations of its customers and generally

F-8

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

does not require collateral for its trade receivables. Additionally, the Company provides long-term financing in
the form of promissory notes when competitive conditions require such financing. In such cases, the Company
may require collateral. Allowances are recognized for potential credit losses. At September 30, 2006, the
Company had two customers that together made up 36% of the Company’s accounts receivable. Subsequent to
September 30, 2006, the Company received full payment from the customer owing the largest receivable.

The Company has a subsidiary located in Russia. Therefore, the Company’s financial results may be
affected by factors such as changes in foreign currency exchange rates, weak economic conditions in Russia or
changes in Russia’s political climate. The Company’s consolidated balance sheet at September 30, 2006 reflected
approximately $3.4 million of net working capital related to its Russian subsidiary. This subsidiary both receives
its revenues and pays its expenses primarily in rubles. This subsidiary received approximately $4.2 million of its
income in U.S. dollars as a result of intercompany sales to the Company’s subsidiary located in the U.S. To the
extent that transactions of this subsidiary are settled in rubles, a devaluation of the ruble versus the U.S. dollar
could reduce any contribution from the Company’s Russian subsidiary to its consolidated results of operations as
reported in U.S. dollars. The Company does not hedge the market risk with respect to its operations in Russia;
therefore, such risk is a general and unpredictable risk of future disruptions in the valuation of Russian rubles
versus U.S. dollars to the extent such disruptions result in any reduced valuation of the Russian subsidiary’s net
working capital or future contributions to its consolidated results of operations.

Inventories

The Company records a write-down of its inventory when the cost basis of any manufactured product,
including any estimated future costs to complete the manufacturing process, exceeds its net realizable value.
Inventories are stated at the lower of cost (as determined by the first-in, first-out method) or market value.

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets include prepayments for insurance and inventory purchases, assets

held for sale, manufacturing supplies and other current assets.

Property, Plant and Equipment and Rental Equipment

Property, plant and equipment and rental equipment are stated at cost. Depreciation expense is calculated

using the straight-line method over the following estimated useful lives:

Expenditures for renewals and betterments are capitalized. Repairs and maintenance are charged to expense
as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the
accounts and any gain or loss thereon is reflected in the statement of operations.

Patents

Patents are amortized over the life of the patent or the estimated life of the patent, whichever is shorter.
Intellectual property is being amortized using the straight-line method over five years. Patent amortization

F-9

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

expense was approximately $0.2 million during each of fiscal years 2006, 2005 and 2004. Intellectual property
amortization expense was approximately $0.5 million during each of fiscal years 2006, 2005 and 2004. The
estimated amortization for the five succeeding years is approximately $0.5 million, $ 0.2 million, $0.2 million,
$0.2 million and $0.2 million for the fiscal years ending September 30, 2007, 2008, 2009, 2010, and 2011,
respectively.

Impairment of Long-lived Assets

The Company’s long-lived assets are reviewed for

impairment whenever an event or change in
circumstances indicates the carrying amount of an asset or group of assets may not be recoverable. The
impairment review, if necessary, includes a comparison of expected future cash flows (undiscounted and without
interest charges) to be generated by an asset group with the associated carrying value. If the carrying value of the
asset group exceeds the expected future cash flows, an impairment loss is recognized to the extent that the
carrying value of the asset group exceeds its fair value.

Goodwill

Goodwill represents the excess of the purchase price of purchased businesses over the estimated fair value
of the acquired business’ net assets. Goodwill is reviewed for impairment at least annually. The Company has
elected to make September 30 the annual impairment assessment date and will perform additional impairment
tests if a change in circumstances occurs that would more likely than not reduce the fair value of goodwill below
its carrying amount. The assessment is performed in two steps: step one is to compare the carrying value of the
net assets of the subject reporting unit to its respective fair value for potential impairment and if potential losses
are identified, step two is to measure the impairment loss. Step two involves allocating the calculated fair value
to all of the tangible and identifiable intangible assets of the reporting unit as if the calculated fair value was the
purchase price of the business combination. The Company performed step one at September 30, 2006 and 2005
and found that there were no impairments at those times; thus, step two was not necessary.

Other Assets

Other assets include $2.3 million and $0.8 million of long-term notes receivable as of September 30, 2006
and 2005, respectively. Monthly payments on these notes are scheduled to be received by the Company over the
next three years.

Revenue Recognition

The Company primarily derives revenue from the sale, and short-term rental under operating leases, of
seismic instruments and equipment and thermal solutions products. The Company generally recognizes sales
revenues when its products are shipped and title and risk of loss have passed to the customer. The Company
recognizes rental revenues as earned over the rental period. Rentals of the Company’s equipment generally range
from daily rentals to rental periods of up to six months or longer. Except for certain of the Company’s reservoir
characterization products, its products are generally sold without any customer acceptance provisions and its
standard terms of sale do not allow customers to return products for credit. In instances where the customer
requires a significant performance test, the Company does not recognize the revenue attributable to the product
as to which the performance test applies until the performance test is satisfied. Collection of this revenue may
occur at various stages of production or after delivery of the product, and is not refundable to the customer. Most
of the Company’s products do not require installation assistance or sophisticated instruction.

F-10

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

The Company recognizes revenue when all of the following criteria are met:

•

Persuasive evidence of an arrangement exists. The Company operates under a purchase order/contract
system for goods sold to customers, and under rental/lease agreements for equipment rentals. These
documents evidence that an arrangement exists.

• Delivery has occurred or services have been rendered. For product sales, the Company does not
recognize revenues until delivery has occurred or performance measures are met. For rental revenue, the
Company recognizes revenue when earned.

•

The seller’s price to the buyer is fixed or determinable. Sales prices are defined in writing in a
customer’s purchase order, purchase contract or equipment rental agreement.

• Collectibility is reasonably assured. The Company evaluates customer credit to ensure that collectibility

of revenue is reasonably assured.

Occasionally seismic customers are not able to take immediate delivery of products which were specifically
manufactured to the customer’s specifications. These occasions generally occur when the customers face
logistical issues such as project delays or delays with their seismic crew deployment. In such instances, the
customers may ask the Company to hold the equipment for a short period of time until they can take physical
delivery of the product (referred to as “bill and hold” arrangements). The Company does not modify its normal
billing and credit terms for these types of sales. As of September 30, 2006, there were no sales under bill and
hold arrangements.

Deferred Revenue

Deferred revenue represents progress payments related to the delivery of a reservoir characterization system.
The system is scheduled to be recognized as revenue in the first quarter of fiscal 2007 upon delivery to the
customer.

Research and Development Costs

The Company expenses research and development costs as incurred. Research and development costs

include salaries, employee benefit costs, department supplies, direct project costs, and other related costs.

Product Warranties

The Company offers a standard product warranty obligating it

to repair or replace products with

Stock-Based Compensation

In the first quarter of fiscal 2006, the Company adopted Statement of Financial Accounting Standards
(“SFAS 123R”), “Share-Based Payment”, which revises SFAS 123, “Accounting for Stock-Based Compensation”.
The Company has elected to use the “modified prospective method” for existing grants which requires the
Company to expense the unvested portion of these grants over the remaining vesting period. Additionally, grants
made after adoption are to be valued and expensed over the applicable vesting period. The Company uses the
Black-Scholes model to value its new stock option grants under SFAS 123R. SFAS 123R also requires the
Company to estimate forfeitures in calculating the expense related to stock-based compensation. In addition,
SFAS 123R requires the Company to reflect the benefits of tax deductions in excess of recognized compensation
cost to be reported as a financing cash inflow. As a result of the adoption of SFAS 123R, the Company recorded
stock-based compensation expenses of $0.6 million for the fiscal year ended September 30, 2006.

Prior to fiscal year 2006, the Company accounted for stock-based compensation granted to employees under
the intrinsic value method of recognition and measurement principles, as discussed in the provisions of APB
Opinion No. 25, “Accounting for Stock Issued to Employees”, and related interpretations. The Company utilized
the Black-Scholes option valuation model to value stock options for pro forma presentation of income and per
share data as if the fair value based method in SFAS 123 had been used to account for stock-based compensation.
The following table illustrates the effect (in thousands, except per share amounts) on net income and earnings per
share for fiscal years ended September 30, 2005 and 2004 as if the Company’s had applied the fair value
recognition provisions of SFAS 123 (in thousands except per share amounts):

The fair value of options granted during the fiscal years ended September 30, 2006, 2005 and 2004 were
estimated using the Black-Scholes option-pricing model with a dividend yield of zero for each of the three years.
This estimation assumed risk-free interest rates of 4.6%, 4.3% and 4.5%; and expected volatility of 56.0%,
55.0% and 65.0%; with an expected option term for key employees of 6.25 years, 5 years and 5 years for fiscal
years 2006, 2005 and 2004, respectively. Expected volatility was determined based on the historical volatility of
the underlying shares over a period consistent with the expected term of the option. The expected term of the
options granted in fiscal year 2006 is 6.25 years, as computed using the simplified method as described in
Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin (“SAB”) No. 107, “Share-Based
Payment”. Expected volatilities are based on the historical volatility of the Company’s stock and other factors.

Financial Instruments

Fair value estimates are made at discrete points in time based on relevant market information. These
estimates may be subjective in nature and involve uncertainties and matters of significant judgment and,

F-12

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

therefore, cannot be determined with precision. The Company believes that the carrying amounts of its financial
instruments, consisting of cash and cash equivalents, accounts and notes receivable, accounts payable and long-
term debt, approximate the fair values of such items.

Foreign Currency Gains and Losses

The assets and liabilities of OYO’s foreign subsidiaries have been translated into U.S. dollars using the
exchange rates in effect at the balance sheet date. Results of operations have been translated using the average
exchange rates during the year. Resulting translation adjustments have been recorded as a component of
accumulated other comprehensive income (loss) in stockholders’ equity. Foreign currency transaction gains and
losses are included in the statement of operations as they occur.

Derivatives

The Company records all derivatives on the balance sheet at fair value. Changes in derivative fair values
will either be recognized in earnings as offsets to the changes in fair value of related hedged assets, liabilities and
firm commitments or for forecasted transactions, deferred and recorded as a component of accumulated other
comprehensive income until the hedged transactions occur and are recognized in earnings. Until September 30,
2004, the Company purchased printheads from OYO Japan whereby such purchases were denominated in
Japanese yen. The Company routinely attempted to hedge its currency exposure on these purchases by entering
into foreign currency forward contracts with a bank. The purpose of entering into these forward hedge contracts
was to eliminate variability of cash flows associated with foreign currency exchange rates on amounts payable in
Japanese yen. The Company’s forward contracts with the bank were considered derivatives. The Company
recorded these foreign currency forward contracts on the balance sheet and marked them to fair value at each
reporting date. Resulting gains and losses are reflected in other income and deductions within the accompanying
consolidated financials and were not material for the fiscal years ended September 30, 2006, 2005 and 2004. At
September 30, 2006, the Company had no foreign currency forward contracts or yen-denominated accounts
payable.

Shipping and Handling Costs

Amounts billed to a customer in a sales transaction related to reimbursable shipping and handling costs are
included in revenues and the associated costs incurred by the Company for reimbursable shipping and handling
costs are reported as an expense in cost of sales. The Company had shipping and handling costs of $0.4 million
for each of the fiscal years ended September 30, 2006, 2005 and 2004.

Income Taxes

The Company follows the liability method of accounting for income taxes whereby deferred tax assets and
liabilities are determined based on the differences between the financial reporting and tax basis of assets and
liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are
expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to
their estimated realizable value.

Recent Accounting Pronouncements

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs” (“SFAS 151”). This statement
amends the guidance in ARB No. 43, Chapter 4, “Inventory Pricing,” to clarify the accounting for abnormal
amounts of idle facility expense, freight, handling costs and wasted material (spoilage). SFAS 151 requires that
those items be recognized as current-period charges. In addition, this statement requires the allocation of fixed
production overhead to costs of conversion be based upon the normal capacity of the production facilities. The

F-13

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

Company adopted the provisions of SFAS 151 as of October 1, 2005. The adoption of SFAS 151 did not have a
material effect on the Company’s consolidated financial statements.

On December 16, 2004,

the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets, an
amendment of APB Opinion No. 29” (“SFAS No. 153”). SFAS No. 153 replaces the exception from fair value
measurement in APB Opinion No. 29 for nonmonetary exchanges of similar productive assets with a general
exception from fair value measurement for exchanges of nonmonetary assets that do not have commercial
substance. A nonmonetary exchange has commercial substance if the future cash flows of the entity are expected
to change significantly as a result of the exchange. The Company adopted the provisions of SFAS No. 153 as of
October 1, 2005. The adoption of SFAS No. 153 did not have a material effect on the Company’s consolidated
financial statements.

In March 2005, the FASB issued Interpretation No. 47 (“FIN 47”), Accounting for Conditional Asset
Retirement Obligations – an interpretation of FASB Statement No. 143, to clarify the term “conditional asset
retirement obligation”, which refers to legal obligations for which companies must perform asset retirement
activity for which the timing and/or method of settlement are conditional upon future events that may or may not
be within the control of the entity. However, the obligation to perform the asset retirement is unconditional,
despite the uncertainty that exists surrounding the timing and method of settlement. Uncertainty about the timing
and method of settlement for a conditional asset retirement obligation (“ARO”) should be considered in
estimating the ARO when sufficient information exists. FIN 47 clarifies when sufficient information exists to
reasonably estimate the fair value of an ARO. This interpretation is effective for the Company as of the end of its
2006 fiscal year. The adoption of FIN 47 did not have a material effect on the Company’s consolidated financial
statements.

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections – a replacement
of APB Opinion No. 20 and FASB Statement No. 3.” (“SFAS No. 154”) SFAS No. 154 requires retrospective
application to prior periods’ financial statements for changes in accounting principle, unless it is impracticable to
determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also requires
that retrospective application of a change in accounting principle be limited to the direct effects of the change.
Indirect effects of a change in accounting principle should be recognized in the period of the accounting change.
SFAS No. 154 also requires that a change in depreciation, amortization, or depletion method for long-lived
non-financial assets be accounted for as a change in accounting estimate affected by a change in accounting
principle. SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years
beginning after December 15, 2005. The adoption of SFAS No. 154 is not expected to have a material effect on
the Company’s consolidated financial statements.

In June 2006, the FASB issued Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income
Taxes – an interpretation of FASB Statement No. 109, to clarify certain aspects of accounting for uncertain tax
positions, including issues related to the recognition and measurement of those tax positions. This interpretation
is effective for fiscal years beginning after December 15, 2006, and therefore will apply beginning with the
Company’s 2008 fiscal year. The Company is in the process of evaluating the impact of this interpretation.

In September 2006, the FASB issued SFAS No. 157 (SFAS 157), “Fair Value Measurements.” Among other
requirements, SFAS 157 defines fair value and establishes a framework for measuring fair value and also
expands disclosure about the use of fair value to measure assets and liabilities. SFAS 157 will be effective
beginning with the Company’s fiscal year beginning on October 1, 2008. The Company is evaluating the impact
of SFAS 157 on its financial position and results of operations.

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108,
“Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year

F-14

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

Financial Statements” (SAB 108), which provides interpretive guidance on how the effects of the carryover or
reversal of prior year misstatements should be considered in quantifying a current year misstatement. The
guidance is applicable for fiscal years ending after November 15, 2006. The Company does not believe SAB 108
will have a material effect on its consolidated financial statements.

2. Acquisitions:

The Company’s subsidiary in Russia, OYO-GEO Impulse International, LLC (“OYO-GEO Impulse”),
manufactures international standard geophone sensors and related seismic products for the Russian and
international seismic marketplaces. In October 2005, the Company purchased for $0.1 million the remaining 3%
ownership interest in this entity from the minority shareholder. OYO-GEO Impulse is now a wholly-owned
subsidiary of the Company.

The allowance for doubtful accounts represents the Company’s best estimate of probable credit losses. The
Company determines the allowance based upon historical experience and a review of its balances. Accounts
receivable balances are charged off against the allowance whenever it is probable that the receivable will not be
recoverable. The Company does not have any off-balance-sheet credit exposure related to its customers.

At September 30, 2006 and September 30, 2005, the Company’s current notes receivable were $1.4 million
and $3.0 million, respectively. The Company also had notes receivable of $2.3 million and $0.8 million classified
as long-term at September 30, 2006 and September 30, 2005, respectively. The long-term trade notes receivable

F-15

are classified on the balance sheet as other assets. Notes receivable are generally collateralized by the products
sold, and bear interest at rates ranging up to 11.3% per year. The notes receivable at September 30, 2006 will be
due at various times through March 2009. The Company’s annual maturities of notes receivable will be
approximately $1.4 million, $1.6 million and $0.7 million in the fiscal years ending September 30, 2007, 2008

years 2006, 2005 and 2004, respectively. The Company had fully depreciated assets of $7.7 million and $8.2
million in use at September 30, 2006 and 2005, respectively.

7. Intellectual Property; Film Supplier Developments:

In April 2002, the Company purchased for $2.3 million certain intellectual property rights from its then
primary supplier of dry thermal film (the “Former Primary Film Supplier”). Such purchase gave the Company

F-16

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

exclusive ownership of all technology used by the Former Primary Film Supplier to manufacture dry thermal
film used in the thermal imaging equipment the Company manufactures. Such purchase included technology then
existing and any dry thermal film technology thereafter developed by the Former Primary Film Supplier for use
in the Company’s equipment. The Company also entered into an amended supply agreement pursuant to which
the Former Primary Film Supplier agreed to provide the Company with dry thermal film. In connection with the
purchase, the Company agreed to license the technology to the Former Primary Film Supplier on a perpetual
basis so long as it could meet predefined quality and delivery requirements. If the Former Primary Film Supplier
could not meet such requirements, the agreement provided the Company with the right to use the technology
itself or to license the technology to any third party to manufacture dry thermal film.

On July 3, 2002, the Former Primary Film Supplier filed a Chapter 11 reorganization petition in Federal
Bankruptcy Court for the Western District of New York. At the date of such bankruptcy filing, the Company had
$3.4 million of long-term assets carried on its balance sheet as a result of the transactions with the Former
Primary Film Supplier described above.

Shortly thereafter, the Former Primary Film Supplier ceased providing the Company with dry thermal film.
As a result, the Company began using the technology it purchased from the Former Primary Film Supplier to
manufacture its own brand of dry thermal film and continued to purchase large quantities of dry thermal film
from an alternative film supplier (the “Other Film Supplier”).

As a result of the bankruptcy filing by the Former Primary Film Supplier, the Company recorded a $1.2
million charge in its third quarter of fiscal year 2002 due to the ultimate uncertainty of realization of value on
certain assets, particularly certain prepaid purchase benefits and other benefits under the amended supply
contract with the Former Primary Film Supplier. The Company continues to believe there has not been any
impairment in the value of the intellectual property it acquired from the Former Primary Film Supplier because
of its ability to utilize the intellectual property to manufacture dry thermal film either internally or elsewhere.

On December 10, 2002, the Company received a notice of claim, in connection with the Former Primary
Film Supplier’s bankruptcy, for alleged preferential payments made by the Former Primary Film Supplier to it in
the period before filing of the bankruptcy proceeding in the approximate amount of $259,000. The Company
recorded a provision for this claim based upon its estimate of the likelihood of a liability and probable loss. On
July 7, 2004, an amended claim was filed against the Company and the amount of the alleged preferential
payments made by the Former Primary Film Supplier was increased to approximately $895,000. On January 20,
2006, a motion to amend was filed regarding the claims pending against the Company. On August 28, 2006, the
motion to amend was denied. The Former Primary Film Supplier’s bankruptcy proceeding has been converted to
a Chapter 7 liquidation proceeding, and a trustee has been appointed for the bankrupt estate. The Company is
unable at this time to estimate the likelihood of a liability arising out of this supplemental claim or the amount, if
any, of probable loss. The Company intends to continue to vigorously defend against the remaining claims under
the overall circumstances of its relationship with the Former Primary Film Supplier. At present, the Company
does not know whether it will make any claims against the Former Primary Film Supplier or others, and it is
unable to predict whether any additional claims will be made against it in connection with the Former Primary
Film Supplier’s bankruptcy proceeding as to any aspect of its relationship with the Former Primary Film
Supplier. The Company is unable at this time to predict the outcome and effects of this situation.

On November 22, 2004, several of the Company’s subsidiaries entered into a credit agreement (the “Credit
Agreement”) with a bank. Under the Credit Agreement as amended on September 19, 2005 and June 16, 2006,
the Company’s borrower subsidiaries can borrow up to $20.0 million secured principally by their accounts
receivable, inventories and equipment. The Credit Agreement expires on November 21, 2007. The Credit
Agreement limits the incurrence of additional indebtedness, requires the maintenance of certain financial ratios,
restricts the Company’s and the borrower subsidiaries’ ability to pay dividends and contains other covenants
customary in agreements of this type. At September 30, 2006, there were borrowings of $2.9 million under the
Credit Agreement, $0.3 million of standby letters of credit were outstanding and additional borrowings available
of $16.8 million. The Company is not subject to a borrowing base and is able to borrow the full $20.0 million
subject to it remaining in compliance with certain covenants. The Company believes that the ratio of total
liabilities to tangible net worth and the asset coverage ratio could prove to be the most restrictive. The interest
rate for borrowing under the Credit Agreement is, at the Company’s option, a discounted prime rate or a LIBOR
based rate.

The Company’s long-term debt will mature as follows (in thousands):

The Company is self-insured for certain losses related to employee medical claims. The Company has
purchased stop-loss coverage for individual claims in excess of $100,000 per claimant per year in order to limit
its exposure to any significant levels of employee medical claims. Self-insured losses are accrued based on the
Company’s historical experience and on estimates of aggregate liability for uninsured claims incurred using
certain actuarial assumptions followed in the insurance industry.

10. Employee Benefits:

The Company’s employees are participants in the OYO Geospace Corporation Employee’s 401(k)
Retirement Plan (the “Plan”), which covers substantially all eligible employees in the United States. The Plan is a
qualified salary reduction plan in which all eligible participants may elect to have a percentage of their
compensation contributed to the Plan, subject to certain guidelines issued by the Internal Revenue Service. The
Company’s share of discretionary matching contributions was approximately $0.4 million, $0.3 million and $0.3
million in fiscal years 2006, 2005 and 2004, respectively.

The Company’s stock incentive plans in which employees may participate are discussed in Note 11 in these

Consolidated Financial Statements.

The Company’s employees are also participants in the OYO Geospace Corporation Fiscal Year 2006 Bonus
Plan (the “Bonus Plan”). Every employee of the Company is eligible to participate in Tier I of the Bonus Plan
except for the Company’s Russian employees, who participate in a local plan. Under Tier I, employees share
proportionally in the Company’s profit based on each employee’s relative payroll. The Tier I bonus pool is
established by accruing 30% of consolidated pretax profits (before bonus) above a specified range. Selected
employees are eligible to participate in Tier II of the Bonus Plan, which tier applies after Tier I is fully funded.
The Tier II Bonus pool is established by accruing 30% of consolidated pretax profits (before bonus) within a
range specified for Tier I. Under Tier II, participants share in the bonus pool based on their respective working
groups meeting predefined goals. Senior executive officers are eligible to participate in Tier III, which only
applies after Tiers I and II have been fully funded. The Tier III bonus pool is established by accruing 30% of
consolidated pretax profits (before bonus) within a specified range above the range specified in Tier I and II. The
Company recorded bonus expense of $3.0 million, $0.2 million and $1.2 million for the fiscal years 2006, 2005
and 2004, respectively.

11. Stockholders’ Equity:

In September 1997, the board of directors and stockholders approved the 1997 Key Employee Stock Option
Plan (the “Employee Plan”), and, following an amendment thereto, there has been reserved an aggregate of
1,125,000 shares of common stock for issuance thereunder. In November 1997, the board of directors and
stockholders approved the Company’s 1997 Non-Employee Director Plan (the “Director Plan”) and following an
amendment thereto, there has been reserved an aggregate of 150,000 shares of common stock for issuance
thereunder. At September 30, 2006, the shares of common stock available for grant under the Employee Plan and
Director Plan were 303,500 and 45,721, respectively.

Under the Employee Plan, the Company is authorized to grant nonqualified and incentive stock options to
purchase common stock and restricted stock awards of common stock to key employees of the Company.
Options have a term not to exceed ten years, with the exception of incentive stock options granted to employees
owning ten percent or more of the outstanding shares of common stock, which have a term not to exceed five
years. The exercise price of any option may not be less than the fair market value of the common stock on the
date of grant. In the case of incentive stock options granted to an employee owning ten percent or more of the
outstanding shares of common stock, the exercise price of such option may not be less than 110% of the fair
market value of the common stock on the date of grant. Options vest over a four-year period commencing on the
date of grant in 25% annual increments. Under the Employee Plan, the Company may issue shares of restricted
stock to employees for no payment by the employee or for a payment below the fair market value on the date of
grant. The restricted stock is subject to certain restrictions described in the Employee Plan, with no restrictions
continuing for more than ten years from the date of the award.

The Company has not issued any shares of restricted stock under the Employee Plan since August 1, 2001.
All issued shares of restricted stock are fully vested; thus there are no outstanding shares of restricted stock. The
prior issuances by the Company of restricted stock were recorded at the fair value of the stock subject to those
awards and were recorded as a component of stockholders’ equity, with a credit to additional paid-in capital. The
Company recorded compensation expense based on the vesting criteria of the individual awards. The Company
will account for future issuances of restricted stock awards in accordance with applicable guidelines, which
require that stock-based awards be measured and recognized at fair value. All factors for the valuation of such
awards will be determined under the Black-Scholes option-pricing model.

The Company established the Director Plan pursuant to which options to purchase shares of common stock
are granted annually to non-employee directors and pursuant to which a portion of the annual fees paid for the
services of such non-employee directors is payable in shares of common stock based on the fair market value
thereof at the date of grant. Options granted under the Director Plan have a term of ten years. The exercise price
of each option granted is the fair market value of the common stock on the date of grant. Options vest over a
one-year period commencing on the date of grant.

Effective November 5, 1999, the board of directors approved the OYO Geospace Corporation 1999 Broad-
Based Option Plan (the “Broad-Based Plan”) and reserved an aggregate of 50,000 shares for issuance thereunder.
Under the Broad-Based Plan, the Company is authorized to issue to all employees (except executive officers and
employee directors) nonqualified stock options to purchase common stock of the Company. These options have a
term not to exceed ten years. The exercise price of any broad-based option may not be less than the fair market
value of the common stock on the date of grant. These options vest over a one-year period commencing on the
date of grant. There were 18,700 shares available for grant under this plan at September 30, 2006.

The current deferred income tax liability of $132,000 is related to the Company’s Russian subsidiary and is
not netted against the Company’s other current deferred income tax assets which were derived in other taxing
jurisdictions. This liability is included in accrued expenses and other current liabilities on the balance sheet.

In fiscal year 2004, the Company (i) realized a $3.6 million award received as a result of the successful
performance of a reservoir characterization system it sold in fiscal year 2002, and (ii) increased its projections of
future domestic and foreign source taxable income due to improving market conditions. As a result, the Company
reversed a $0.8 million valuation allowance established in fiscal year 2003.

Under the liability method, a valuation allowance is provided when it is more likely than not that some
portion or all of the deferred tax assets will not be realized. Based on the Company’s expectation that the
deductible temporary differences will reverse during periods in which the Company generates net taxable income
or during periods in which losses can be carried back to offset prior year taxes, management believes that the
Company will realize the benefit of its net deferred income tax asset.

The financial reporting bases of investments in foreign subsidiaries exceed their tax bases. A deferred tax
liability is not recorded for this temporary difference because the investment is essentially permanent. A reversal
of the Company’s plans to permanently invest in these foreign operations would cause the excess to become
taxable. At September 30, 2006 and 2005, the temporary difference related to undistributed earnings for which no
deferred taxes have been provided was approximately $9.9 million and $10.3 million, respectively. The
Company will need to reassess and reassert its ability and intent to indefinitely reinvest the remaining foreign
earnings in order to continue the application of the exception under APB 23.

From time to time the Company is the subject of audits by various tax authorities that can result in claims
and assessments and additional tax payments, penalties and interest. At present, there are no pending audits of the
Company’s past tax returns.

As a result of the Company’s income for the year ended September 30, 2006, the Company was able to
utilize previously benefited items of $1.0 million in foreign tax credits, federal operating loss carryforwards of
$0.5 million, alternative minimum tax carryforwards of $0.3 million, research and experimentation credits of
$81,000 and general business credits of $46,000. The Company utilized substantially all of such credits and
carryforwards available at September 30, 2006.

Utilizing the provisions of the American Jobs Creation Act of 2004, the Company repatriated earnings of

$3.5 million from foreign subsidiaries.

13. Earnings Per Common Share:

Basic earnings per share is computed by dividing net earnings available to common stockholders by the
weighted average number of common shares outstanding during the period. Diluted earnings per share is

determined on the assumption that outstanding dilutive stock options have been exercised and the aggregate
proceeds as defined were used to reacquire common stock using the average price of such common stock for the
period.

equivalent shares outstanding for purposes of basic and diluted earnings per share (in thousands, except share and

respectively, were not included in the calculation of weighted average shares for diluted earnings per share
because their effects were antidilutive.

14. Related Party Transactions:

Sales to OYO Japan and other affiliated companies were approximately $0.6 million, $0.4 million and $0.5
million during fiscal years 2006, 2005 and 2004, respectively. Purchases of inventory and equipment from OYO
Japan were approximately $0.1 million, $0.1 million and $0.8 million during fiscal years 2006, 2005 and 2004,
respectively.

15. Commitments and Contingencies:

Operating Leases

The Company leases certain equipment under short-term cancelable operating leases;

therefore the
Company does not have future minimum rental commitments under noncancelable operating leases. Rent
expense was approximately $0.1 million, $0.1 million, and $0.2 million for fiscal years 2006, 2005 and 2004,
respectively.

Legal Proceedings

From time to time the Company is a party to what it believes is routine litigation and proceedings that may
be considered as part of the ordinary course of its business. Legal expenses related to such matters are expensed
as incurred. The Company is not aware of any current or pending litigation or proceedings that could have a
material adverse effect on the Company’s results of operations, cash flows or financial condition, although the
Company continues to monitor developments in the bankruptcy proceeding by its Former Primary Film Supplier
and the Former Primary Film Supplier’s existing claim against the Company described in Note 7.

During fiscal year 2006, the Company combined the manufacturing operations for its Seismic and Thermal
Solutions business segments. While the combination of the two segments resulted in more streamlined
operations, the Company no longer segregates and reports certain balance sheet accounts for these segments.
As a result, the Company has discontinued the reporting of business segment balance sheet information.
