## Dear Fellow Shareholder,

When our technology team sets out to design a new product, they are always focused on providing solutions to our customers' problems. Sometimes the changes they design result in incremental improvements in specifications that – while important – don't result in earth-shattering announcements. Many of our modifications in geophone design and capabilities fall into this category: year in and year out we keep improving our geophones and offering greater functionalities so that our customers can gather better data across broader ranges of conditions. It's important to our customers and good for our bottom line, but not grist for the news mill.

Sometimes, however, our team’s desire to make our customers’ working day easier and more productive results in a sweeping transformation. The GSR (Geospace Seismic Recorder) system represents that kind of transformation, changing both the way our customers can now acquire data and the types of data acquisition projects they can undertake. Our new high sensitivity GS-One geophone is also representative of this kind of sweeping transformation.

In seeking to use new technology to address some of the fundamental stumbling blocks that routinely frustrate our customers, we ended up designing a new seismic acquisition system and a single point geophone that are radically transforming our customers' field operations. Our customers can acquire more data – more efficiently than ever before. They can take on acquisition projects they never dreamed of undertaking – and they can do so with ease.







## What Makes Our GSR System So Special?

For years seismic contractors have travelled the globe acquiring data to uncover oil and gas deposits. The recording systems they’ve used have all been connected by cable – in some instances hundreds of miles of cable – so that the data acquired at each individual location could be transmitted back to the recording truck where it was stored on tapes for processing and interpretation.

Until recently, cabled systems were the predominant mode of land seismic data acquisition. And, until recently, our customers would routinely spend considerable time and effort coping with cables. Shipping the cables from one job to another could be a logistical nightmare requiring eighteen-wheelers or large container vessels.

Deploying the cables across a 3D survey frequently required large numbers of individual field workers to carry 50 - 80 pounds of cable and equipment, which increased the likelihood of accidents and injuries to workers even when terrain or weather conditions were decent. In inhospitable environments such as the arctic winter or in jungles or across mountainous regions, the possibility of injury during cable deployment increased exponentially.

Once the cable was deployed it had to be maintained, which could mean several hours of troubleshooting each day, tracking down faults or



breaks in the lines due to grazing animals, traffic or mishaps. In addition, contractors frequently faced severe cable deployment constraints due to roads, rivers, or other geographical hazards as well as landowner concerns, regulatory rules and environmental issues.

The cable-free GSR system significantly reduces the logistics, health, safety and environmental issues associated with cable-based land seismic data acquisition. A GSR unit with a GS-One geophone weighs about seven pounds and several units can easily be transported in backpacks without strain or injury. Seismic data acquisition crews using the GSR system can accomplish far more, with far fewer people. Risks of accident or injury are much lower because fewer people are needed to deploy the systems and because the systems weigh so much less and require so little maintenance.

Similarly, the GS-One geophone, in one simple package, provides all the signal fidelity and quality expected in seismic data recording and it effectively replaces larger, heavier, more complicated conventional geophone arrays, which were traditionally comprised of six or twelve geophones. Together, the GSR and GS-One are changing the face of seismic data acquisition.

We set out to develop the GSR data acquisition system in the late 1990s. As shareholders you have watched as we have painstakingly rolled out important precursors to its development. Even our first deep marine system incorporated some of the principles we’re using today. Each year, we’ve added capabilities, or honed our technology to get to this place, where today we offer the most widely accepted and most widely used cableless seismic data acquisition system on the market.






For fiscal year 2010, our revenue was $128.5 million and our net income was $14.1 million, or $2.27 per diluted share. This compares with revenue of $92.9 million and net income of $1.8 million, or $0.29 per diluted share in fiscal year 2009. The strength of our revenue is a reflection of the success of our technological breakthrough.

With the GSR, we have not only transformed the day-to-day operations of our customers, but also we've transformed ourselves – from a manufacturer of parts for systems manufactured by others to a designer and manufacturer of systems ourselves. We are tremendously pleased with both transformations because we believe the key to our success lies in giving our customers exactly what they need to make their day-to-day operations easier and more profitable.

The success stories that follow are our customers' success stories. The quotations at the front of this report aren't propaganda from some PR machine; they are the unqualified reactions from our customers after they've used our GSR system. We're ecstatic with their reviews of this transformational technology and with their confidence in our system as best demonstrated by their repeat business.

We continue to improve our products. It’s who we are and what we’re always about.



Very truly yours,



Gary D. Owens

## What our customers are saying about:

# Performance.

Selecting a cableless acquisition system with a single high-sensitivity GS-One geophone over a more traditional multi-geophone sensor array was an important technical and logistical decision for gathering quality seismic data on Norse Energy’s 3D surveys in upstate New York. They knew reducing the bulk and complexity of multiple geophones would be a significant gain – but random noise and other unknowns made for a little nervousness.

A small preliminary seismic program was shot. The data was processed right away and compared to a conventional 2D line that had been shot by another company through the same area.

“I held my breath as I loaded the data set,” said Alan Leaver, VP of Exploration at Norse Energy. “It was unbelievable. The data was at least
as good as the 2D line… and the big benefit is when you go into the field, instead of having 6 or 8 or 12 geophones strung out over 100, 200 feet, you have a single buried geophone. The footprint is miniscule compared to what it was previously.”





“I was a little apprehensive to begin with and now feel totally vindicated for going with this system. I’m very pleased with it.”

Weighing just seven pounds per unit, the small, self-contained and man-portable GSR revolutionizes the process of seismic lay-down and pickup – and everything in between. The GSR system has transformed seismic crews' daily routines. Instead of spending hours in the field each day troubleshooting, making repairs and finding and replacing faulty equipment, crews can now check the entire spread of active devices with a quick sweep, and where needed, swap out system components in minutes. With the GSR system, seismic contractors are discovering that the financially productive part of their day starts a lot earlier and lasts a lot longer.

## What our customers are saying about:

## Mobility.

“With the GSR, you get three components: the battery, the box, and a single-element phone. Boom. If something goes wrong, I swap it out,” says Charles Bundrant, President of Green World Geophysical. “At seven pounds per channel, it can go in a backpack. If I go into swamp, I just throw it into an air boat and go.”

That mobility translates to huge logistical advantages. “Everything goes away with a wireless crew. Everything becomes invisible,” says Mike Lauren, President of Viking Geophysical. “There are no more major highways. There are no more major creeks, there are no more villages, and there are no longer any challenges to prohibit you from getting high production at the end of the day.”



## “

“I don’t believe that anybody could compete with us when it comes to mobilization.”

## Safety.

Deploying cables across a 3D survey can require large numbers of field workers to carry heavy loads of cable and equipment, increasing the likelihood of accidents and injuries.

Inhospitable weather, rough terrain, and every hour in a vehicle or out in the elements increase that risk exponentially.

But data acquisition crews using the GSR system can accomplish far more with far fewer people and far less exposure.

Fewer people, fewer vehicles, less weight and less time out in the field checking cables and making repairs – all these factors cut injury risks dramatically.

“We have this lightweight system out there… we put this 2½ pound box on the ground, we hook it up to a small battery with a set of very lightweight land geophones, and so overall there is very little strenuous activity taking place on a seismic crew,” observes Mike Lauren, President of Viking Geophysical.

## “

“…now we have a 20-man crew as opposed to say… a 75- to 100-man crew. So with the GSR system, it lowers the count of your men, which lowers the count of vehicles used, fuel consumption…”

## PART I

## Item 1. Business

## Overview

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 its 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. Demand for our products has been, and will likely continue to be, vulnerable to downturns in the economy and the oil and gas industry in general. During most of fiscal year 2010, oil and natural gas prices remained at fairly consistent levels, but during fiscal years 2009 and 2008 there was substantial volatility in oil and natural gas prices. Please refer to the risks discussed under the heading “Risk Factors” for more information.

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 thermal media 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

A seismic energy source and a seismic data recording system are combined to acquire seismic data. We provide many of the components of seismic data recording systems, including data acquisition systems, geophones, hydrophones, multi-component sensors, seismic leader wire, geophone strings, connectors, seismic telemetry cables and other seismic related products. On land, our customers use our data acquisition systems, geophones, leader wire, cables and connectors to receive and measure seismic reflections resulting from an energy source to data recording 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 recording 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 seismic sensor, cable and connector products are compatible with most major competitive seismic data acquisition systems currently in use, and sales result primarily from seismic contractors purchasing our products as components of new seismic data acquisition systems or to repair and replace components of seismic data acquisition systems already in use.

During fiscal year 2008, we announced the development of a land-based wireless (or nodal) data acquisition system. Each nodal station operates independently and therefore can be deployed in virtually unlimited channel configurations. Rather than utilizing interconnecting cables as required by most traditional land data acquisition systems, each nodal station operates as an independent data collection system. As a result, our nodal system requires less maintenance, which we believe allows our customers to operate more effectively and efficiently because of its reduced environmental impact, lower weight and ease of operation. Our nodal system is designed into configurations ranging from one to four channels per station. Since its introduction, we have delivered over



39,000 channels of our land-based nodal acquisition system. We also have over 9,000 additional channels available for rent by our customers and we intend to increase our rental fleet up to 30,000 total channels in fiscal year 2011.

In October 2009, we introduced a marine-based nodal data acquisition system. Similar to our land nodal system, the marine nodal system can be deployed in virtually unlimited channel configurations and does not require interconnecting cables between each station. Our deepwater versions of this nodal system can be deployed in depths of up to 3,000 meters.

Our wholly-owned subsidiary in the Russian Federation manufactures international standard geophones, sensors, seismic leader wire, seismic telemetry cables and related seismic products for customers in the Russian Federation 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” in this Annual Report on Form 10-K.

## 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 effects of production. Utilizing these tools, 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 an application pioneered by us allowing operators and service companies to monitor and measure the results of fracturing operations.

## Emerging Technology Products

Our products continue to develop and expand beyond seismic applications through the utilization of our existing engineering experience and manufacturing capabilities. We 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 and connector products, such as those used in connection with global positioning products and water meter applications.

## 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 printers include both thermal imagersetters for graphics applications and thermal plotters for seismic applications. In addition, our thermal solutions products include direct-to-screen systems, thermal printheads, dry thermal film, thermal transfer ribbons and other thermal media. Our thermal imaging solutions produce images ranging in size from 12 to 54 inches wide and in resolution from 400 to 1,200 dots per inch. We market our thermal imaging solutions to a variety of industries, including the screen printing, point-of-sale, signage, flexographic and textile markets. We also continue to sell these products to our seismic customers.



The quality of thermal imaging is determined primarily by the interrelationship between a thermal printhead and the thermal media, be it film, ribbon, or any other media. We manufacture 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 private label high-quality dry thermal media for use in our thermal printers and direct-to-screen systems. In addition, we are continuously engaged in efforts to develop new lines of dry thermal film and ribbon in order to improve the image quality of our media for use with our printheads. 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 and media improvements.

## Products and Product Development

## Seismic Products

Our seismic product lines currently consist of land and marine nodal seismic data acquisition systems, high-definition reservoir characterization products and services, geophones and hydrophones, including multi-component geophones and hydrophones, seismic leader wire, geophone string and acquisition system connectors, seismic telemetry cables, marine seismic cable retrieval and steering devices and specialized data acquisition systems targeted at conventional and 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.

In fiscal year 2008, we introduced “wireless” land and marine nodal seismic data acquisition systems which allow our customers to deploy an unlimited quantity of autonomous nodal stations without the requirement to deploy and maintain lengthy power/communication cables. Our nodal systems are designed into configurations ranging from one to four channels per station. Since its introduction, we have delivered over 39,000 channels of our land-based nodal acquisition system. We also have over 9,000 additional channels available for rent by our customers and we intend to increase our rental fleet up to 30,000 total channels in fiscal year 2011.

Our high-definition reservoir characterization products 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 reservoir imaging and monitoring. Modular architecture allows virtually unlimited channel expansion. 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 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.



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

In order to take advantage of our existing cable manufacturing facilities and capabilities in Houston, we are designing and selling cable products to the offshore oil and gas and offshore construction industries. The production of offshore marine cables requires specialized design capabilities and manufacturing equipment. We also utilize these design capabilities and manufacturing equipment to produce deepwater reservoir characterization products. We are aggressively working to diversify our seismic product lines as well as utilizing our manufacturing capabilities to develop and produce products for use in other industries.

## Thermal Solutions Products

Our thermal solutions products include thermal imagsetters for graphics applications and thermal plotters for seismic applications. In addition, our thermal solution products include thermal printheads and thermal media products. 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 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 data acquisition systems, geophones, hydrophones, geophone string connectors, leader wire and telemetry cables are SERCEL (a division of CGGVeritas), ION Geophysical (“ION”), INOVA (a joint venture formed in 2009 between ION and Bureau of Geophysical Prospecting, a subsidiary of China National Petroleum Company) and Steward Cable (a division of Amphenol Corporation). Furthermore, entities in China affiliated with SERCEL as well as other Chinese manufacturers produce low-cost geophones meeting current industry standards.

We believe that the principal keys for success in the seismic instruments and equipment market are technological superiority, product durability, reliability, and customer support. We also believe that price and product delivery are always important considerations for our customers. In general, most customers prefer to standardize data acquisition systems, geophones and hydrophones, particularly if they are used by seismic companies which have multiple crews which are able to support each other. This standardization makes it difficult for competitive manufacturers to gain market share from other manufacturers with existing customer relationships.

As mentioned above, a key factor for seismic instruments and equipment manufacturers is durability under harsh field conditions. Instruments and equipment must meet not only 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.



We believe our primary competitors for our “wireless” nodal seismic data acquisition systems are SERCEL, Fairfield Industries and INOVA.

With respect to our marine seismic 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 competitors in the manufacture of our streamer depth positioning device, or “birds,” are ION and SERCEL.

We believe our primary competitors for our deepwater cabled reservoir characterization and monitoring systems are SERCEL, ION and Petroleum Geo-Services ASA.

We believe our primary competitors for high-definition borehole seismic data acquisition systems are Avalon and SERCEL.

We believe our primary competitors for rental of seismic equipment are Mitcham Industries, Inc. and Seismic Equipment Solutions.

## Thermal Solutions Products

We believe that the primary competitors to our thermal imaging business segments include emulsion producers like KIWO USA, Inc. as a distributor of direct-to-screen technologies, Colour Scanned Technology as a manufacturer of direct-to-screen technologies, iSys Group as a manufacturer of thermal technologies for oil and gas exploration applications, as well as manufacturers of alternative technologies such as inkjet devices distributed and used for film output. Also, as we advance the resolution capabilities of direct thermal imaging technology, we expose ourselves to additional competition in the more traditional wet-film and direct-to-plate imagesetting marketplace. A key competitive factor in this market is producing equipment that is technologically advanced, yet cost effective.

## Suppliers

We produce our own brand of dry thermal film internally. We also purchase a substantial quantity of dry thermal film directly from Agfa-Gevaert or through its international distributors.

We do not currently experience any significant difficulties in obtaining raw materials from our suppliers for the production of our seismic or thermal imaging 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 of our manufacturing and assembly operations, 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 held 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. One customer comprised 13.2%, 12.0% and 11.5% of our revenues during the fiscal years 2010, 2009 and 2008, respectively. The following table describes our sales by customer type (in thousands):

<table><tr><td rowspan="2"></td><td colspan="3">YEAR ENDED SEPTEMBER 30,</td></tr><tr><td>2010</td><td>2009</td><td>2008</td></tr><tr><td>Seismic exploration customers</td><td>$ 89,777</td><td>$59,084</td><td>$ 92,578</td></tr><tr><td>Seismic reservoir customers</td><td>14,600</td><td>12,020</td><td>15,784</td></tr><tr><td>Industrial customers</td><td>10,397</td><td>7,939</td><td>10,250</td></tr><tr><td>Thermal solutions customers</td><td>12,955</td><td>13,028</td><td>15,201</td></tr><tr><td>Other</td><td>804</td><td>789</td><td>682</td></tr><tr><td></td><td>$128,533</td><td>$92,860</td><td>$134,495</td></tr></table>

During the last two years, there has been substantial uncertainty in the capital markets and access to credit remains uncertain. Due to these conditions, certain of our customers may continue to curtail their seismic contracting activities which would result in a decrease in demand for our products. Furthermore, certain of our customers could experience an inability to pay suppliers, including us, in the event they are unable to access the capital markets to fund their business operations. These risks are more fully described under the heading “Risk Factors” in this Annual Report on Form 10-K.

## 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 regarding our marine seismic cable retrieval devices to be of particular value to us. This patent is scheduled to expire 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 and thermal imaging technologies. We have incurred company-sponsored research and development expenses of $9.9 million, $8.1 million and $8.9 million during the fiscal years ended September 30, 2010, 2009 and 2008, respectively.

## Employees

As of September 30, 2010, we employed approximately 891 people predominantly on a full-time basis, of which 494 were employed in the United States and 348 in the Russian Federation. Our employees in the Russian Federation 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. During periods of improved energy commodity prices, the capital spending budgets of oil and natural gas operators tend to expand, which results in increased demand for our products. Conversely, in periods when these energy commodity prices deteriorate, the demand for our products generally weakens. Historically, the markets for oil and gas have been volatile. During the last two years, there has been substantial volatility and a decline in oil and natural gas prices, which 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 impact 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 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 our wireless nodal seismic data acquisition systems, as well as other 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 short-term 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 4.2 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, 2010 averaged approximately 25,000 shares. 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 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. With the recent global financial crisis and tight commercial credit availability, some of our customers relying on credit markets as the source of funds for their capital spending may experience significant 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.

## 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 three competitors in our seismic business segment currently offer a broader range of instruments and equipment for sale than we do. Further, certain of our competitors may 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 may also result in significant price competition that could have a material adverse effect on our results of operations.

## We Have a Limited Market for Our Seismic Products

In our seismic business segment, we market our traditional products to seismic service contractors and to large, independent and government-owned oil and gas companies. We estimate that, based on published industry sources, fewer than 50 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

Based on customer billing data, net sales outside the United States accounted for approximately 33.5% of our net sales during fiscal year 2010; however, we believe the percentage of sales outside the United States is much higher as many of our products are first delivered to a domestic location and ultimately shipped to a foreign location. We again expect net sales outside of the United States to represent a substantial portion of our net sales for fiscal year 2011 and subsequent years. Substantially all of our sales from the United States are made in U.S. dollars, though from time to time we may 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 United States, including the risk of war, terrorist activities, civil disturbances, embargo and government activities and foreign attitudes about conducting business activities with the United States, all of which may disrupt markets. A portion of our manufacturing is conducted through our subsidiary OYO-GEO Impulse, which is based in the Russian Federation. Our business could be directly affected by political and economic conditions in the Russian Federation. Boycotts, protests, governmental sanctions and other actions in the region could adversely affect our ability to operate profitably. The risk of doing business in the Russian Federation 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 U.S. 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 the Russian Federation, we may not be able to transfer cash balances to the United States to assist with debt servicing or other obligations.

Our subsidiaries in the Russian Federation and in Canada together reported operating losses of $1.3 million and $3.3 million, respectively, for fiscal years 2010 and 2009 primarily due to difficult seismic market conditions. These market conditions are influenced by macro-economic conditions such as the world-wide economic crisis, credit availability, crude oil and natural gas commodity price volatility and other factors impacting world-wide energy exploration activities. In addition, other factors contributed to these difficult conditions such as high tax regimes, the over-supply of natural gas as recently seen in North America, intense competitive pricing pressures, and reduced demand by our Houston-based operations for products manufactured by our Russian subsidiary. We cannot assure you that these conditions will improve in the near term or that these subsidiaries will not experience these difficult market conditions again in the future, and these subsidiaries may generate future operating losses, asset impairments charges, or closure if we are unable to stabilize their operations.

## Unfavorable Currency Exchange Rate Fluctuations Could Adversely Affect Our Results of Operations

The reporting currency for our financial statements is the U.S. dollar. However, certain of our subsidiaries are located in countries other than the United States. The assets, liabilities, revenues and costs of these foreign subsidiaries are denominated in currencies other than U.S. dollars. To prepare our consolidated financial



statements, we must translate those assets, liabilities, revenues and expenses into U.S. dollars at then-applicable exchange rates. Consequently, increases and decreases in the value of the U.S. dollar versus these other currencies will affect the amount of these items in our consolidated financial statements, even if their value has not changed in their original currency. These translations could result in significant changes to our results of operations from period to period. For the fiscal year ended September 30, 2010, approximately 8.5% of our consolidated revenues related to the operations of our foreign subsidiaries.

## 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 located in the United States. 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

At September 30, 2010, OYO Corporation owned indirectly in the aggregate approximately 21.1% 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

The current downturn in the economy, and any economic slowdown in future periods, could adversely affect our business in ways that we cannot predict. During times of economic slowdown, our customers may reduce their capital expenditures and defer or cancel pending projects. Such developments occur even among customers that are not experiencing financial difficulties. 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. Additionally, bankruptcies or financial difficulties among our customers could reduce our cash flows and adversely impact our liquidity and profitability.



Global Capital and Credit Market Issues Could Negatively Affect Our Liquidity and Increase Our Costs of Borrowing

United States and global credit markets have recently experienced significant dislocations and liquidity disruptions which have caused the spreads on prospective debt refinancings to widen considerably. These circumstances materially impacted liquidity in the debt markets, making financing terms for borrowers less attractive, and in certain cases have resulted in the unavailability of certain types of debt financing. Events affecting the credit markets have also had an adverse effect on other financial markets in the United States, which may make it more difficult or costly in the future for us to borrow additional funds. Our business could also be negatively impacted if our suppliers or customers experience disruptions resulting from tighter capital and credit markets or a slowdown in the general economy. Any of these risks could increase our interest expense, or impair our ability to fund our operations or expand our business, which could have a material adverse effect on our financial results.

## We Have a Minimal Disaster Recovery Program at the Pinemont Facility

Due to its proximity to the Texas Gulf Coast, our Pinemont facility is annually subject to the threat of hurricanes, and the aftermath that follows. Hurricanes may cause, among other types of damage, the loss of electrical power for extended periods of time. If we lost electrical power at the Pinemont facility, or if a fire or other natural disaster occurred, we would be unable to continue our manufacturing operations during the power outage because we do not own a generator or any other back-up power source large enough to provide for our manufacturing power consumption needs. We have a backup generator to provide power for our information technology operations. Although we store our back-up data offsite, we do not maintain an alternative facility to run our information technology operations. Additionally, we do not have an alternative manufacturing or operating location in the United States. A significant disruption in our manufacturing and information technology operations could materially and adversely affect our business operations during an extended period of a power outage, fire or other natural disaster.

## The Credit Agreement Imposes Restrictions on Our Business

Several of our subsidiaries are borrowers under a credit agreement with a bank. The credit agreement contains covenants and requires maintenance of certain financial ratios and tests, which impose restrictions on our business and on the business of our borrower-subsidiaries. We currently believe that the most restrictive covenants in the credit agreement are (i) the fixed charge coverage ratio of EBITDA to certain charges, and (ii) the cash flow leverage ratio of total borrowings (excluding real estate borrowings) to adjusted EBITDA. Our ability to comply with these restrictions may be affected by events beyond our control, including, but not limited to, prevailing economic, financial and industry conditions and continuing declines in our sales of products. The breach of any of these covenants or restrictions, as well as any failure to make a payment of interest or principal when due, could result in a default under the credit agreement. Such a default would permit our lender to declare amounts borrowed from it to be due and payable, together with accrued and unpaid interest, and the ability to borrow under the credit agreement could be terminated. If we are unable to repay debt to our lender, the lender could proceed against the collateral securing that debt. While we intend to seek alternative sources of cash in such a situation, there is no guarantee that any alternative cash source would be available, or would be available on terms favorable to us.

## We May Not Be Able to Extend or Replace Our Existing Credit Agreement

Our existing credit agreement with a bank expires in April 2011. While we are attempting to extend or replace our credit agreement, we have no assurance that we will be able to do so or to do so on terms that are commercially satisfactory to us.



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,

• 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. Additionally, in anticipation of customer product orders, from time to time we acquire substantial quantities of inventories, which if not sold or integrated into products within a reasonable period of time, could become obsolete. We would be required to impair the value of such inventories on our balance sheet.

## Item 1B. Unresolved Staff Comments

None.

## Item 2. Properties

As of September 30, 2010, our operations included the following locations:

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



## 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.

On July 8, 2009, the Company received a complaint filed in the United States District Court in Nevada alleging that the Geospace Seismic Recorder (“GSR”), the Company’s newly developed wireless data acquisition system, infringes upon a patent held by Ascend Geo, LLC (“Ascend”). The Company requested and was granted a change in venue to the United States District Court for the Southern District of Texas in Houston (the “Court”). In addition to monetary damages, Ascend requested a preliminary injunction against future sales by the Company of the GSR nodal system. The Company filed its response with the Court requesting that it deny Ascend’s request for a preliminary injunction and, on November 4, 2009, the Court denied Ascend’s request for a preliminary injunction. The Company strongly believes that the GSR nodal system does not violate Ascend’s patent. The Company also strongly believes that Ascend’s patent is not valid and has petitioned the United States Patent and Trademark Office (“PTO”) to re-examine its validity. On November 12, 2009, the PTO found that substantial new questions of patentability were raised by the petition as to each of the claims of the Ascend patent and issued an office action rejecting each of the claims based on prior art that the Company submitted to the PTO. Based on the PTO’s initial finding of invalidity of Ascend’s patent claims, the Company petitioned the Court to stay the litigation until the PTO can complete its reexamination of Ascend’s patent. The Court accepted the Company’s request on December 11, 2009. On May 20, 2010, after full briefing from both Ascend and the Company, the PTO examiner found all claims to be invalid. On September 17, 2010, Ascend filed a notice of appeal to the Board of Patent Appeals and Interferences, and, so the reexamination continues. According to Ascend’s website, it ceased business operations on July 15, 2010. The Company will continue to defend vigorously its right to build and sell its GSR products and based on developments to date, the Company believes that the matter will be resolved satisfactorily in its favor. The Company further believes that Ascend’s claims are without merit and intends to seek recovery of its attorney fees. At this time, however, the Company is unable to predict the outcome of its dispute regarding Ascend’s patent or Ascend’s claims.

## 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 Annual Report on Form 10-K, including 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 Annual 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 thermal media products targeted at the screen print, point of sale, signage and textile market sectors. We have been manufacturing thermal imaging products in 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 Annual Report on Form 10-K.

## Worldwide Economic Slowdown

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. The 2008 domestic financial crisis arising out of the meltdown of the subprime lending market caused significant distress to many global financial lending institutions, leading to a broader global financial crisis and a tightening of the availability of commercial credit. Recessionary fears, combined with a decline in worldwide demand for energy, caused energy commodity prices to decline substantially from an all-time high of approximately $145 per barrel in July 2008. As expected, these events led to a decline in energy exploration activities in North America and in certain international markets, and we began to see the effects of this decline on our business during the first fiscal quarter of 2009. We saw demand for many of our seismic exploration products decline, including significant declines in our Russian and Canadian seismic exploration markets. Despite signs of an economic recovery earlier in 2010, the recent falterings in the European markets have renewed the uncertainty of the worldwide economic situation. We continue to believe that some of our seismic customers may not possess the financial resources ultimately required to survive the prolonged downturn in energy exploration, while others have scaled back their activities until financial markets stabilize further and demand for exploration activities increases.

The uncertainty of these global economic matters and their ultimate impact on energy exploration activities and on our customers' ability to access credit markets is difficult to forecast, and a decline in the demand for our seismic exploration products is likely to continue for the present time. Due to the sporadic demand for our seismic reservoir products, we have often described this portion of our seismic business as “lumpy.” In this current environment, we expect our seismic business levels will be even more erratic, including potential orders for our new land and marine-based nodal acquisition systems. Singular events may result in severe swings in our future revenues in both positive and negative directions. If these economic events continue into the foreseeable future, they could have a material adverse impact on our revenues and profits in future years.

While we have seen some recovery in the demand for our products, we remain cautious regarding the future and we continue to monitor the impact that these economic conditions may have on our operations. We believe



that our current cash balances, cash flow from operations and cash borrowings available under our credit facility will provide sufficient resources to meet our working capital liquidity needs for the next twelve months.

## April 2010 Offshore Drilling Operations Disaster

In April 2010, a deepwater Gulf of Mexico drilling rig, Deepwater Horizon, sank after a blowout and fire, causing substantial loss of life and property and substantial environmental damage to U.S. coastal areas in the Gulf of Mexico. In response to this incident, the U.S. Department of the Interior issued a notice on May 30, 2010 implementing a six-month moratorium on certain drilling activities in the Gulf of Mexico. Implementation of the moratorium was blocked by a U.S. district court, which was subsequently affirmed on appeal, but on July 12, 2010, a new moratorium was issued applying to deep-water drilling operations that use subsea blowout preventers or surface blowout preventers on floating facilities. On December 1, 2010, the U.S. Department of the Interior announced that the Atlantic Coast and the eastern Gulf of Mexico would be closed to offshore oil and gas drilling through 2017. We are not able at this time to predict the risks these developments may present to the Company and the ultimate effect thereof on our business that is related to marine and coastal oil and gas exploration activities.

## Consolidated Results of Operations

The economic slowdown adversely affected our product revenues in fiscal year 2009. In fiscal year 2009, we experienced declines in almost every major product category in each of our business segments. In fiscal year 2010 product revenues increased from fiscal year 2009 in most product categories. We have not sold any large-scale seabed reservoir characterization products since fiscal year 2007, although a smaller seabed system was sold in fiscal year 2010. These reservoir characterization products generally have higher profit margins than our traditional seismic exploration products.

In fiscal years 2008 and 2009, revenues from our reservoir characterization products declined substantially from fiscal year 2007 when we recognized $16.2 million of revenues from the sale of a seabed reservoir characterization system. In fiscal year 2010 revenues increased substantially, but not to the level of fiscal year 2007. As we have reported in the past, our sales and operating profits have varied significantly from quarter-to-quarter, and even year-to-year, and are expected to continue that trend in the future, especially when our quarterly financial results are impacted by the presence or absence of these relatively large, but somewhat erratic, shipments of seismic seabed and/or borehole reservoir characterization systems. At present, we do not have any large orders for seabed reservoir characterization products in our backlog, although we remain optimistic about on-going discussions with customers concerning these products. The quote-to-contract time for large permanent and retrievable seabed seismic data acquisition systems is generally quite long, and since these sales are not recognized in our financial statements until the products are shipped and/or accepted by our customer, the exact timing of any future sales can dramatically affect our quarterly results.

In fiscal years 2010 and 2009, our subsidiaries located in the Russian Federation and in Canada experienced significant declines in sales and, together, generated operating losses of $1.3 million and $3.3 million, respectively. The difficult seismic market conditions in the Russian Federation resulted from a decline in oil exploration activities precipitated in part by the severe drop in crude oil commodity prices (relative to prices in prior years) and a higher federal tax imposed upon Russian producers of crude oil for export. In addition, our Houston-based manufacturing operation significantly reduced the purchase of products manufactured by our Russian subsidiary in an effort to stabilize and eventually reduce our consolidated inventory levels. The resulting low factory utilization, combined with intense competition for declining seismic product orders in the Russian market, contributed to the poor financial results of our Russian subsidiary during fiscal years 2010 and 2009. In regards to our subsidiary in Canada, high levels of natural gas storage and low natural gas demand in North America significantly reduced natural gas-oriented seismic exploration activities both in the United States and in Canada, resulting in low levels of product sales and the under-utilization of our seismic rental equipment. The



lower level of sales recorded by our Canadian subsidiary was not adequate to offset fixed costs associated with rental equipment depreciation and facility utilization as well as general overhead costs. We expect to see signs of improvement in the seismic market conditions in the Russian Federation and in Canada in the near future and we believe the operating results of these subsidiaries in fiscal year 2011 will improve from fiscal year 2010.

## Overview

Fiscal Year 2010 Compared to Fiscal Year 2009

Consolidated net sales for fiscal year 2010 increased $35.7 million, or 38.4%, from fiscal year 2009. The higher level of sales stems from the increase in customer demand for our seismic products and particularly robust demand for our land-based wireless (or nodal) data acquisition systems. The increased demand for our seismic products in fiscal year 2010 was driven by higher crude oil commodity prices and increased natural gas exploration activities in North America.

Consolidated gross profits for fiscal year 2010 increased by $20.8 million, or 78.2%, from fiscal year 2009. The increase in gross profits was caused by an increase in sales of our products, improved factory utilization and a favorable product mix.

Consolidated operating expenses for fiscal year 2010 increased $3.1 million, or 13.6%, from fiscal year 2009. Increased operating expenses primarily resulted from a $2.3 million increase of incentive compensation resulting from higher consolidated pretax profits, and general expense increases due to higher sales volume. These operating expense increases were partially offset by lower bad debt expenses resulting from improved collection of our outstanding accounts receivable.

The U.S. statutory rate applicable to us for fiscal years 2010 and 2009 was 35.0% and 34.0%, respectively; however, our effective tax rate was 32.6% and 46.8% for fiscal years 2010 and 2009, respectively. The lower effective tax rate in fiscal year 2010 resulted from (i) the impact of the manufacturers'/producers' deduction available in the United States, (ii) a revaluation of our United States net deferred tax assets from 34.0% to 35.0%, (iii) the revaluation of a tax loss carryback for our Canadian subsidiary, and (iv) a reduction in our contingent tax expenses. The United States Congress has not extended the provision for research and experimentation credits.



beyond calendar year 2009; therefore, the Company has not recorded any related tax benefit of such credits beyond its first quarter ended December 31, 2009. The higher effective tax rate for fiscal year 2009 resulted primarily from pretax losses in foreign taxing jurisdictions having lower statutory tax rates than the U.S. statutory rate.

## Fiscal Year 2009 Compared to Fiscal Year 2008

Consolidated net sales for fiscal year 2009 decreased $41.6 million, or 31.0%, from fiscal year 2008. The decrease in sales resulted from the decline in customer demand for our seismic products as a result of the effects of the worldwide economic slowdown and its impact on energy exploration activities.

Consolidated gross profits for fiscal year 2009 decreased by $20.5 million, or 43.5%, from fiscal year 2008. The decline in gross profits was caused by a decline in sales of our products, competitive pricing initiatives and higher manufacturing costs resulting from under-utilized factory capacity.

Consolidated operating expenses for fiscal year 2009 decreased $4.5 million, or 16.5%, from fiscal year 2008. Reduced operating expenses reflected initiatives taken by management in response to the decline in sales, and also reflect a $1.9 million reduction of incentive compensation expenses caused by lower consolidated pretax profits.

The U.S. statutory rate applicable to us for the periods reported was 34.0% and 35.0%, respectively; however, our effective tax rate was 46.8% and 30.7% for fiscal years 2009 and 2008, respectively. The higher effective tax rate for fiscal year 2009 resulted primarily from pretax losses in foreign taxing jurisdictions having lower statutory tax rates than the U.S. statutory rate. The lower tax rate in fiscal year 2008 resulted from pretax income earned in foreign taxing jurisdictions having lower statutory tax rates than the U.S. statutory tax rate, and the impact of research and experimentation tax credits available in the United States.

## Segment Results of Operations

## Seismic Products

## Fiscal Year 2010 Compared to Fiscal Year 2009

Net Sales. Sales of our seismic products for fiscal year 2010 increased $35.7 million, or 45.2%, from fiscal year 2009. The increase in sales is due to a higher demand for most of our seismic products caused by increased oil and gas exploration activities worldwide. In addition, we experienced robust demand for our land-based wireless (or nodal) data acquisition system.

Operating Income. Operating income from sales of our seismic products for fiscal year 2010 increased $18.4 million, or 173.4%, from fiscal year 2009. The higher operating income is directly related to (i) improved product sales and product mix, (ii) higher factory utilization resulting from increased manufacturing activities, (iii) improved operating results from our subsidiary in the Russian Federation, and (iv) the leveraging of fixed operating expenses over a greater volume of revenues.

## Fiscal Year 2009 Compared to Fiscal Year 2008

Net Sales. Sales of our seismic products for fiscal year 2009 decreased $39.6 million, or 33.4%, from fiscal year 2008. The decline in sales was due to a decline in the demand for all of our seismic products, including a $10.7 million decline in sales from our Russian and Canadian operations. Reduced product demand resulted from a reduction in oil and gas exploration and development activities precipitated by the global economic crisis and the prevailing uncertainty about future oil and gas commodity prices.

Operating Income. Operating income from sales of our seismic products for fiscal year 2009 decreased $16.5 million, or 60.9%, from fiscal year 2008. The decline in our operating income was directly related to the



significant decline in our seismic product sales, competitive pricing initiatives and under-utilization of our manufacturing capacity. In particular, our Russian and Canadian subsidiaries generated $3.3 million of operating losses during fiscal year 2009 due to significantly lower sales, under-utilization of plant and equipment, and intense pricing pressures from competitors for our commodity seismic products.

## Thermal Solutions Products

## Fiscal Year 2010 Compared to Fiscal Year 2009

Net Sales. Sales of our thermal solutions products for fiscal year 2010 decreased $73,000, or 0.6%, from fiscal year 2009. We consider this small decrease to be somewhat normal due to recurring fluctuations in product sales volume and not associated with any long-term trend.

Operating Income. Our operating income from our thermal solutions products for fiscal year 2010 increased $27,000, or 7.3%, from fiscal year 2009. The increase in operating income is caused by increased production efficiencies.

## Fiscal Year 2009 Compared to Fiscal Year 2008

Net Sales. Sales of our thermal solutions products for fiscal year 2009 decreased $2.2 million, or 14.3%, from fiscal year 2008. The decline in sales resulted from weaker demand of all thermal product categories due to a weakening economic climate and tight credit markets impacting many of our smaller customers in this business segment.

Operating Income. Our operating income from our thermal solutions products for fiscal year 2009 decreased $0.9 million, or 71.2%, from fiscal year 2008. The decline in operating income was caused by the decline in our thermal product sales and higher manufacturing costs.

## Incentive Compensation Program

We adopted an incentive compensation program for fiscal year 2010 whereby most employees will be eligible to begin earning incentive compensation if the Company reaches a five percent pretax return on stockholders' equity, determined as of September 30, 2009. To be eligible to participate in this incentive compensation program, employees must participate in our Core Values Program. Based on our experience in prior years, we expect one hundred percent of our eligible employees to participate in the Core Values Program. The incentive compensation program does not apply to the employees of our Russian subsidiary as such employees participate in a locally administered bonus program. Certain non-executive employees are required to achieve performance goals to earn a significant portion of their total incentive compensation award. Any bonus awards earned under this program in fiscal year 2010 will be paid out to eligible employees after the end of the fiscal year.

Upon reaching the five percent threshold under this proposed program, an incentive compensation accrual will be established equal to 16.7 percent of the amount of any consolidated pretax profits above the five percent pretax return threshold. The maximum aggregate bonus available under the program for fiscal year 2010 is $3.4 million and we have accrued $3.3 million of incentive compensation expense for fiscal year 2010.

## Liquidity and Capital Resources

At September 30, 2010, we had $33.5 million in cash and cash equivalents. For fiscal year 2010, we generated approximately $30.0 million of cash from our operating activities. Sources of cash generated in our operating activities include net income of $14.1 million. Additional sources of cash include net non-cash charges of $6.6 million for deferred income tax expense, depreciation, amortization, stock-based compensation, inventory



obsolescence and bad debts. Other sources of cash included (i) a $6.7 million decrease in inventories due to improved management activities, (ii) a $5.0 million increase in accrued expenses primarily resulting from higher incentive compensation costs resulting from higher levels of pretax income and (iii) a $1.9 million increase in income taxes payable primarily resulting from the increase in taxable income. These sources of cash were offset by (i) a $2.7 million increase in accounts and notes receivable resulting from higher levels of sales, (ii) a $0.9 million decrease in accounts payable due to increases in purchases of raw materials and (iii) a $0.9 million decrease in prepaid expenses and other resulting from the timing of funding our payrolls.

Over the last 18 months, we have reduced our inventory levels significantly in order to liquidate excess quantities on hand, and to generate cash flows to reduce our outstanding indebtedness. Although our levels of inventory again declined in fiscal year 2010, we continue to be subject to high levels of inventory obsolescence expense since our exposure to obsolete and slow moving inventories continues in the current environment. We continue to give substantial attention to the management of our inventories in this area.

For fiscal year 2010, we used approximately $6.1 million of cash in investing activities primarily resulting from our capital expenditures for rental equipment. In addition, we transferred $0.3 million of inventories to our rental equipment during fiscal year 2010 which had a non-cash impact. Due to high demand for our wireless rental equipment, we estimate that our total capital expenditures in fiscal year 2011 could be approximately $20.0 million, including non-cash additions to our rental fleet. We expect these capital expenditures will be financed from our cash on hand, internal cash flow and/or from borrowings under our Credit Agreement.

For fiscal year 2010, we generated approximately $1.3 million of cash in the financing activities of our operations. Sources of cash included $3.3 million of proceeds from the exercise of stock options and related tax benefits. These sources of cash were offset by $1.8 million of principal payments under mortgage loans and a $0.1 million payment as a penalty for early extinguishment of debt.

At September 30, 2009, we had $8.6 million in cash and cash equivalents. For fiscal year 2009, we generated approximately $17.3 million of cash in operating activities. Sources of cash generated in our operating activities resulted from net income of $1.8 million. Additional sources of cash include net non-cash charges of $7.5 million for deferred income tax expense, depreciation, amortization, stock-based compensation, inventory obsolescence and bad debts. Other sources of cash included a $14.3 million decrease in accounts and notes receivable due to improved collections and lower levels of product sales, and a $3.2 million decrease in inventories. These sources of cash were offset by (i) a $4.2 million decrease in accrued expenses primarily resulting from a decline in payroll-related costs due to employee headcount reductions and lower incentive compensation costs resulting from lower levels of pretax income, (ii) a $3.4 million decrease in accounts payable due to declines in purchases of raw materials and other expense reductions and (iii) a $1.4 million decrease in income taxes payable primarily resulting from the decrease in taxable income.

For fiscal year 2009, we used approximately $1.7 million of cash in investing activities resulting from our capital expenditures. We estimate that our total capital expenditures in fiscal year 2010 will be approximately $3.5 million. We expect these capital expenditures will be financed from our internal cash flow and/or from borrowings under our Credit Agreement.

For fiscal year 2009, we used approximately $9.7 million of cash in the financing activities of our operations, resulting from $10.0 million of principal payments under the Credit Agreement and $0.7 million principal payments for our mortgage loans. These uses of cash were offset by $1.0 million of proceeds from the exercise of stock options and related tax benefits.

At September 30, 2008, we had $1.6 million in cash and cash equivalents. For fiscal year 2008, we used approximately $8.0 million of cash in operating activities. Sources of cash generated in our operating activities primarily resulted from our net income of $14.2 million. Additional sources of cash included non-cash charges to our net income of $0.4 million for deferred taxes, $4.6 million for depreciation and amortization, $1.6 million for



bad debts, and $1.0 million for inventory obsolescence. These sources of cash were more than offset by (i) a $15.1 million increase in inventories resulting from the production of new products (primarily for our new wireless data acquisition system) and from growth in our work-in-process inventories resulting from an increase in our customer order backlog, (ii) a $13.7 million increase in trade accounts and notes receivable resulting from sales to customers requesting long-term financing assistance combined with a general increase in collection days, and (iii) the removal of a $0.6 million gain on disposal of property, plant and equipment.

For fiscal year 2008, we used approximately $9.1 million of cash in investing activities, including $9.8 million for capital expenditures, which was partially offset by $0.7 million of cash proceeds from the sale of property, plant and equipment, primarily from the sale of a portion of a surplus property located in the Russian Federation.

For fiscal year 2008, we generated approximately $16.4 million of cash in the financing activities of our operations, resulting from (i) $9.1 million of net borrowings under the Credit Agreement, (ii) $8.8 million borrowed under a term loan secured by a mortgage on our Pinemont facility and (iii) $1.6 million of proceeds from the exercise of stock options and related tax benefits. These sources of cash were offset by $3.1 million of principal payments under mortgage loans.

On November 22, 2004, several of our subsidiaries entered into a credit agreement (the “Original Credit Agreement”) with a bank. The Original Credit Agreement has been amended periodically since 2004, and most recently on April 30, 2009 (as so amended, the “Credit Agreement”). Under the Credit Agreement, our borrower subsidiaries can borrow up to $25.0 million principally secured by their accounts receivable, inventories and equipment. The Credit Agreement expires on April 30, 2011. The Credit Agreement limits the incurrence of additional indebtedness, requires the maintenance of certain financial ratios, restricts our and our subsidiaries’ ability to pay dividends and contains other covenants customary in agreements of this type. We believe the most restrictive covenants in the Credit Agreement are (i) the fixed charge coverage ratio of EBITDA to certain charges, and (ii) the cash flow leverage ratio of total borrowings (excluding real estate borrowings) to adjusted EBITDA. The interest rate for borrowings under the Credit Agreement is a LIBOR based rate with a margin spread of 300-400 basis points depending upon the maintenance of certain ratios. At September 30, 2010, there were no borrowings under the Credit Agreement, standby letters of credit outstanding in the amount of $0.4 million and additional borrowings available of $24.6 million. At September 30, 2009, there were no borrowings under the Credit Agreement, standby letters of credit outstanding in the amount of $0.9 million and additional borrowings available of $15.9 million.

We are seeking to extend the credit facility and expect to be able to do so, but have no assurances that we will be able to do so. We anticipate that the existing cash balance as of September 30, 2010, cash flow from operations and borrowing available under our existing credit facility, assuming it is extended, or borrowing under a new credit facility will provide adequate cash flows and liquidity for the next twelve months to satisfy capital expenditure requirements and scheduled debt payments and to fund operations.

On March 13, 2008, we obtained an $8.8 million mortgage from a bank. The proceeds were used to pay off our existing $2.6 million mortgage on the Pinemont facility and the remaining proceeds were used to repay outstanding borrowings under the Credit Agreement. The mortgage is collateralized by the Pinemont property and buildings. The mortgage interest rate is a floating rate based on LIBOR plus 150 basis points.



A summary of future payments owed for contractual obligations and commercial commitments as of September 30, 2010 are shown in the table below (in thousands):

## 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 for medical expenses, product warranty reserves, intangible assets, stock-based compensation and deferred income tax assets. We base our estimates on historical experience and various other factors, including the impact from the current economic conditions, that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different conditions or assumptions.

Our normal credit terms for trade receivables are 30 days. In certain situations, credit terms for trade receivables may be extended to 60 days or longer and such receivables generally do not require collateral. Additionally, we provide long-term financing in the form of promissory notes when competitive conditions require such financing and, in such cases, we may require collateral. We perform ongoing credit evaluations of our customers' accounts and notes receivable and allowances are recognized for potential credit losses.

Our 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 of the related assets. 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.

Management makes judgments regarding the interpretation of tax laws that might be challenged upon an audit and causes changes to previous estimates of tax liability. In addition, we operate within multiple taxing jurisdictions and are subject to audit in these jurisdictions as well as by the Internal Revenue Service. In management’s opinion, adequate provisions for income taxes have been made for all open tax years. The potential outcomes of examinations are regularly assessed in determining the adequacy of the provision for income taxes and income tax liabilities. Management believes that adequate provisions have been made for reasonable and foreseeable outcomes related to uncertain tax matters.



We record a write-down of our inventories 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. Our subsidiary in the Russian Federation uses an average cost method to value its inventories.

We periodically review the composition of our inventories to determine if market demand, product modifications, technology changes, excessive quantities on-hand and other factors hinder our ability to recover its investment in such inventories. Management’s assessment is based upon historical product demand, estimated future product demand and various other judgments and estimates. Inventory obsolescence reserves are recorded when such assessments reveal that portions or components of our inventory investment will not be realized in our operating activities.

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 nine 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 the customer requires a significant performance test for our new and unproven products, 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 revenue from the sale of large-scale reservoir characterization products may occur at various stages of production or after delivery of the product, and the collected funds are not refundable to the customer.

Most of our products do not require installation assistance or sophisticated instruction. We offer a standard product warranty, which obligates 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 tests 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 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 the customer has a substantial business purpose for ordering the goods on a bill and hold basis,

• 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 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, 2010 and 2008, we had no sales under bill and hold arrangements. As of September 30, 2009, we had recognized $0.6 million of sales under bill and hold arrangements.

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:

- Although crude oil prices have gradually improved in the last 18 months, we believe the impact of the recent worldwide financial crisis and continuing recession, combined with volatile and unsteady energy



commodity prices may constrain oil and gas exploration activities in North America and also in certain international markets. Furthermore, we believe our seismic customers relying on credit markets as the source of funds for their capital spending could be prohibited from purchasing new equipment until financial markets stabilize and demand for exploration activities increases. The uncertainty of these global economic matters and their ultimate impact on energy exploration activities and on our customers' ability to access credit markets may cause demand for our seismic exploration products to decrease.

- In fiscal years 2010 and 2009, our Russian and Canadian seismic operations experienced low product demand, excess manufacturing capacity, intense price competition, low rental equipment utilization and certain asset write-downs resulting from these factors. Together, the seismic activities of these subsidiaries generated an operating loss of $1.3 million in fiscal year 2010 and an operating loss of $3.3 million in fiscal year 2009. We are seeing signs of increased activity in each of these markets, and we believe the operating results of these subsidiaries will improve in fiscal year 2011.

- 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 oil and gas commodity prices, will not cause a significant increase or decrease in demand for our seismic products for the foreseeable future.

- Based upon our current backlog, we expect revenues from our borehole and seabed reservoir characterization products and services to remain level with fiscal year 2010 revenues. Our current product backlog does not contain any orders for large-scale seabed reservoir monitoring systems. If we were to sell such a system in fiscal year 2011, we would expect our revenues for these products to increase significantly.

- We expect revenues from the sale and rental of recent product introductions, such as our wireless nodal seismic data recording systems, to improve during fiscal year 2011.

- We expect demand for our products used in the thermal solutions industry to remain level with fiscal year 2010 revenues.

• We expect sales of our industrial products to remain level with fiscal year 2010.

## Item 7A. Quantitative and Qualitative Disclosures about Market Risk

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. 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 Item.

## Foreign Currency and Operations Risk

One of our wholly-owned subsidiaries, OYO-GEO Impulse, is located in the Russian Federation. Therefore, our financial results may be affected by factors such as changes in foreign currency exchange rates, weak economic conditions in the Russian Federation or changes in its political climate. Our consolidated balance sheet at September 30, 2010 reflected approximately $5.1 million of net working capital related to OYO-GEO Impulse. For third-party transactions, 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 the Russian Federation; therefore, such risk is a general and unpredictable risk of future disruptions in the valuation of 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, 2010, the foreign exchange rate of the U.S. dollar to the ruble was 1:30.7. If the U.S. dollar versus ruble exchange rate were to decline by ten percent, our working capital could decline by $0.5 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 in a gain or loss, respectively, to our consolidated statement of operations. At September 30, 2010, we had outstanding accounts receivable of $7.6 million and $0.1 million from our subsidiaries in Canada and the Russian Federation, respectively. At September 30, 2010, the foreign exchange rate of the U.S. dollar to the Canadian Dollar was 1:0.97 and the foreign exchange rate of the U.S. dollar to ruble was 1:30.7. If the U.S. dollar exchange rate were to decline by ten percent, our intercompany accounts and notes receivable would decline by $0.8 million in Canada and $7,000 in the Russian Federation.

## Floating Interest Rate Risk

The Credit Agreement and the real estate mortgage agreement for our Pinemont facility each contain a floating interest rate. These floating interest rates subject us to the risk of increased interest costs associated with any upward movements in bank market interest rates. Under the Credit Agreement as most recently amended, our borrowing interest rate is a LIBOR based rate plus 300-400 basis points. As of September 30, 2010, we had no borrowings under the Credit Agreement. Under the real estate mortgage agreement, our borrowing rate is a LIBOR based rate plus 150 basis points and as of September 30, 2010 we had $7.7 million outstanding under this agreement at an effective interest rate of 1.8%. Due to the amount of borrowings outstanding under the real estate mortgage agreement and the 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 operations and/or cash flow. At September 30, 2010, based on our current level of borrowings, a 1.0% increase in interest rates would increase our interest expense annually by approximately $77,000.

## 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 Annual Report on Form 10-K and are incorporated herein by reference.

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

None.

## 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 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, 2010 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 as of September 30, 2010.

## 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, 2010. 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 concluded that, as of September 30, 2010, our internal control over financial reporting is effective based on those criteria.

Our internal control over financial reporting as of September 30, 2010 has been audited by UHY LLP, an independent registered public accounting firm, as stated in their report which appears herein.

## Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting that occurred during the Company’s fiscal quarter ending September 30, 2010 that have materially affected, or are reasonably likely to materially affect, the Company’s 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 audited the accompanying consolidated balance sheets of OYO Geospace Corporation and subsidiaries (“the Company”) as of September 30, 2010 and 2009, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three fiscal years in the period ended September 30, 2010. Our audits also included the financial statement schedule listed in the accompanying index. These consolidated financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of OYO Geospace Corporation and subsidiaries as of September 30, 2010 and 2009, and the consolidated results of their operations and their cash flows for each of the three fiscal years in the period ended September 30, 2010, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of OYO Geospace Corporation and subsidiaries' internal control over financial reporting as of September 30, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated December 10, 2010 expressed an unqualified opinion on the effectiveness of the Company's 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 audited OYO Geospace Corporation and subsidiaries' (“the Company”) internal control over financial reporting as of September 30, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (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, included in Part II, Item 9A of this Form 10-K. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit 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. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) 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 (3) 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.

In our opinion, OYO Geospace Corporation and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of September 30, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of OYO Geospace Corporation and subsidiaries as of September 30, 2010 and 2009, and the related consolidated statements of operations, stockholders' equity and cash flows for each of the three fiscal years in the period ended September 30, 2010, and our report dated December 10, 2010, expressed an unqualified opinion on those consolidated financial statements.

# 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, 2010, OYO Corporation U.S.A. (“OYO USA”) owned approximately 21.1% 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 U.S. generally accepted accounting principles. All intercompany balances and transactions have been eliminated.

## Reclassifications

Certain amounts previously presented in the consolidated financial statements have been reclassified to conform to the current year presentation. Such reclassifications had no effect on net income, stockholders' equity or cash flows.

## 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 investments 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.



## OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

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 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, 2010, the Company had two customers comprising 22.3% and 11.1%, respectively, of the Company’s trade accounts receivable. At September 30, 2009, the Company had two customers comprising 16.6% and 11.2%, respectively, of the Company’s trade accounts receivable. The Company had two customers comprising 75.9% and 15.0% of its notes receivable balance at September 30, 2010. The Company had two customers comprising 72.8% and 25.6%, respectively, of its notes receivable balance at September 30, 2009. One customer comprised 13.2%, 12.0% and 11.5% of the Company’s revenues during the fiscal years 2010, 2009 and 2008, respectively.

The Company has a subsidiary located in the Russian Federation. Therefore, the Company’s financial results may be affected by factors such as changes in foreign currency exchange rates, weak economic conditions or changes in political climate within the Russian Federation. The Company’s consolidated balance sheet at September 30, 2010 reflected approximately $5.1 million of net working capital related to this subsidiary. This subsidiary receives a substantial portion of its revenues and pays its expenses primarily in rubles. During the fiscal year ended September 30, 2010, this subsidiary received approximately $3.6 million of its income in U.S. dollars as a result of intercompany sales to the Company’s subsidiary located in the United States. The Company’s consolidated balance sheet at September 30, 2009 reflected approximately $5.0 million of net working capital related to this subsidiary. During the fiscal year ended September 30, 2009, this subsidiary received approximately $1.1 million of its income in U.S. dollars as a result of intercompany sales to the Company’s subsidiary located in the United States. To the extent that transactions of this subsidiary are settled in rubles, a devaluation of the ruble versus the United States dollar could reduce any contribution from this 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 the Russian Federation; therefore, such risk is a general and unpredictable risk of future disruptions in the valuation of rubles versus U.S. dollars to the extent such disruptions result in any reduced valuation of the subsidiary’s net working capital or future contributions to its consolidated results of operations.

## Inventories

The Company records a write-down of its inventories 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. The Company’s subsidiary in the Russian Federation uses an average cost method to value its inventories.

## Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets include prepayments for insurance, inventory purchases, manufacturing supplies and other types of current assets.



# OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

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:

<table><tr><td></td><td>Years</td></tr><tr><td>Rental equipment</td><td>3-10</td></tr><tr><td>Property, plant and equipment:</td><td></td></tr><tr><td>Machinery and equipment</td><td>3-15</td></tr><tr><td>Buildings and building improvements</td><td>10-50</td></tr><tr><td>Other</td><td>5-10</td></tr></table>

Expenditures for renewals and betterments are capitalized. Repairs and maintenance expenditures 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 legal life of the patent or the estimated useful life of the patent, whichever is shorter. Patent amortization expense was approximately $0.2 million during each of fiscal years 2010, 2009 and 2008. Patent amortization expense is estimated to be approximately $0.2 million for each of the fiscal years ending September 30, 2011 and 2012, and approximately $80,000 during fiscal year 2013.

## 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 of the related assets. 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 indicate the carrying value of goodwill may exceed its fair amount. The assessment is performed in two steps: step one is to compare the carrying value of the reporting unit's net assets (including goodwill) 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 goodwill impairment is tested at the Company's seismic segment level as the goodwill relates to the purchase of a seismic related company. The impairment test uses a weighted average cost of capital. The growth rate is based on the projected inflation rate. The Company performed step one at September 30, 2010 and 2009 and found that there were no impairments at those times; thus, step two was not necessary.



# OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

## 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 nine 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 for the Company’s new and unproven products, 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 revenue from the sale of large-scale reservoir characterization products may occur at various stages of production or after delivery of the product, and the collected funds are not refundable to the customer. Most of the Company’s products do not require installation assistance or sophisticated instruction.

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 customers face logistical issues such as project delays or delays with their seismic crew deployment. In these instances, customers have asked 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 considers 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 the Company received that request in writing,

- Whether the customer has a substantial business purpose for ordering the goods on a bill and hold basis,

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

- Whether the Company has any specific performance obligations such that the earning process is not complete,



# OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

- Whether the equipment is segregated from its other inventory and not subject to being used to fill other orders, and

• Whether the equipment is complete and ready for shipment.

The Company does not modify its normal billing and credit terms for these types of sales. As of September 30, 2010 and 2008, there were no sales under bill and hold arrangements. As of September 30, 2009, there were $0.6 million of sales under bill and hold arrangements.

## Deferred Revenue

The Company records deferred revenue when funds are received prior to the recognition of the associated revenue.

## 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 manufacturing defects. The Company maintains a reserve for future warranty costs based on historical experience or, in the absence of historical product experience, management’s estimates. Changes in the warranty reserve are contained in the following table (in thousands):

<table><tr><td>Balance at the beginning of the period (October 1, 2008)</td><td>$ 1,147</td></tr><tr><td>Accruals for warranties issued during the period</td><td>1,400</td></tr><tr><td>Accruals related to pre-existing warranties (including changes in estimates)</td><td>—</td></tr><tr><td>Settlements made (in cash or in kind) during the period</td><td>(1,715)</td></tr><tr><td>Balance at the end of the period (September 30, 2009)</td><td>832</td></tr><tr><td>Accruals for warranties issued during the period</td><td>3,219</td></tr><tr><td>Accruals related to pre-existing warranties (including changes in estimates)</td><td>—</td></tr><tr><td>Settlements made (in cash or in kind) during the period</td><td>(2,673)</td></tr><tr><td>Balance at the end of the period (September 30, 2010)</td><td>$ 1,378</td></tr></table>

## Stock-Based Compensation

Under the FASB share-based payment framework, the Company expenses the grant date fair value of equity awards over the requisite service period. The Company uses the Black-Scholes model to value its new stock option grants. The share-based payment framework also requires the Company to estimate forfeitures in calculating the expense related to stock-based compensation. In addition, the share-based payment framework requires the Company to reflect the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash inflow. The Company recorded stock-based compensation expenses of $0.4 million, $0.3 million and $33,000 for the fiscal years ended September 30, 2010, 2009 and 2008, respectively.



## OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

There were 63,000 and 146,000 stock options granted during fiscal years 2010 and 2009, respectively, and no options granted during fiscal year 2008. The fair value of options granted during the fiscal year ended September 30, 2010 and 2009 was estimated using the Black-Scholes option-pricing model using the following data:

<table><tr><td></td><td>2010</td><td>2009</td></tr><tr><td>Dividend yield rate</td><td>0%</td><td>0%</td></tr><tr><td>Risk-free interest rate</td><td>2.4%</td><td>2.1%</td></tr><tr><td>Expected volatility</td><td>56.6%</td><td>51.4%</td></tr><tr><td>Expected option term</td><td>6.25 years</td><td>6.25 years</td></tr></table>

The computation of expected volatility was based on the historical volatility. Historical volatility was calculated from historical data for the time approximately equal to the expected term of the option award starting from the date of grant. The risk-free interest rate assumption is based upon the U.S. Treasury yield curve in effect at the time of grant for the period corresponding with the expected life of the option. The expected term of options granted is derived from the vesting period and historical information and represents the period of time that options granted are expected to be outstanding.

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, 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 and accounts payable, approximate the fair values of such items as a result of the relative short term nature of such items. The carrying value of long-term debt approximates the fair value as a result of the interest rates reflecting market rates of interest.

## Foreign Currency Gains and Losses

The assets and liabilities of the Company’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.

## 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 in cost of sales. The Company had shipping and handling costs of $0.7 million, $0.6 million and $0.8 million for each of the fiscal years ended September 30, 2010, 2009 and 2008, respectively.

## Income Taxes

Income taxes are presented in accordance with FASB guidance for accounting for income taxes. The estimated future tax effects of temporary differences between the tax bases of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, as well as operating loss and tax credit carrybacks and

Notes to Consolidated Financial Statements—(Continued)

carryforwards are recorded. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities (temporary differences) and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company periodically reviews the recoverability of tax assets recorded on the balance sheet and provides valuation allowances if it is more likely than not that such assets will not be realized.

## Subsequent Events

The Company evaluates events and transactions that occur after the balance sheet date but before the financial statements are issued. The Company evaluated such events and transactions through the date the financial statements were filed electronically with the Securities and Exchange Commission.

## Recent Accounting Pronouncements

In January 2010, the FASB issued guidance to amend the disclosure requirements related to recurring and nonrecurring fair value measurements. The guidance requires new disclosures on the transfers of assets and liabilities between Level 1 (quoted prices in active market for identical assets or liabilities) and Level 2 (significant other observable inputs) of the fair value measurement hierarchy, including the reasons and the timing of the transfers. Additionally, the guidance requires a roll forward of activities on purchases, sales, issuance, and settlements of the assets and liabilities measured using significant unobservable inputs (Level 3 fair value measurements). The guidance will be effective for interim and annual reporting periods beginning after December 15, 2009. The Company adopted this guidance and had no material effect on its consolidated financial statements.

On November 22, 2004, several of the Company’s subsidiaries entered into a credit agreement (the “Original Credit Agreement”) with a bank. The Original Credit Agreement has been amended periodically since 2004, and most recently on April 30, 2009 (as so amended, the “Credit Agreement”). Under the Credit Agreement, the Company’s borrower subsidiaries can borrow up to $25.0 million principally secured by their accounts receivable, inventories and equipment. The Credit Agreement expires on April 30, 2011. The Credit Agreement limits the incurrence of additional indebtedness, requires the maintenance of certain financial ratios,



## OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

restricts the Company and its subsidiaries' ability to pay dividends and contains other covenants customary in agreements of this type. At September 30, 2010, the Company was in compliance with all covenants. The interest rate for borrowings under the Credit Agreement is a LIBOR based rate with a margin spread of 300-400 basis points depending upon the maintenance of certain ratios. At September 30, 2010, there were no borrowings under the Credit Agreement, standby letters of credit outstanding in the amount of $0.4 million and additional borrowings available of $24.6 million. At September 30, 2009, there were no borrowings under the Credit Agreement, standby letters of credit outstanding in the amount of $0.9 million and additional borrowings available of $15.9 million.

On December 30, 2009 the Company paid off a long-term mortgage note with a principal balance outstanding of $1.3 million. The Company was required to pay an additional fee of $137,000 as a result of the early extinguishment of the mortgage note. Such fee is recorded as a component of other income (expense) in the Company’s consolidated statement of operations.

On March 13, 2008, the Company obtained an $8.8 million mortgage from a bank. The proceeds were used to pay off the existing $2.6 million mortgage on the Pinemont facility and to repay outstanding borrowings under the Credit Agreement. The mortgage is collateralized by the Pinemont property and buildings. The mortgage interest rate is a floating rate based on LIBOR plus 150 basis points, or 1.8% at September 30, 2010.

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 $150,000 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.

## 8. 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 $0.5 million, $0.5 million and $0.6 million in fiscal years 2010, 2009 and 2008, respectively.

The Company’s stock incentive plans in which employees may participate are discussed in Note 9 to these Consolidated Financial Statements.

The Company’s employees are also participants in the OYO Geospace Corporation Fiscal Year 2010 Bonus Plan (the “Bonus Plan”). Every employee of the Company is eligible to participate in Tier I of the Bonus Plan except for its employees in the Russian Federation, 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 16.7% of consolidated pretax profits (before bonus) above a specified range. Selected employees are eligible to participate in Tier II of the Bonus Plan, which applies after Tier I is fully funded. The Tier II Bonus pool is established by accruing 16.7% of consolidated pretax profits (before bonus) within a specified range. 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 the Tier I and Tier II pools have been fully funded. The Tier III bonus pool is established by accruing 16.7% of consolidated pretax profits (before bonus) within a specified range above the Tier I and II ranges. The Company recorded bonus expense of $3.3 million, zero and $3.1 million for the fiscal years 2010, 2009 and 2008, respectively.

## 9. Stockholders' Equity:

In September 1997, the board of directors and stockholders approved the 1997 Key Employee Stock Option Plan (the “Employee Plan”), and, following amendments 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, 2010, the shares of common stock available for grant under the Employee Plan and Director Plan were 90,175 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



## OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

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.

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. However, as disclosed in our Current Report on Form 8-K filed with the Securities and Exchange Commission, on February 21, 2007, the Board of Directors of the Company approved a new compensation structure for non-employee directors, as recommended by the Board of Director’s Compensation Committee. Pursuant to an amendment to the Director Plan adopted at the same meeting, the annual options to non-employee directors will no longer be granted. Options granted under the Director Plan prior to the adoption of this amendment 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 19,000 shares available for grant under this plan at September 30, 2010.

Notes to Consolidated Financial Statements—(Continued)

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 assets.

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, 2010 and 2009, the temporary difference related to undistributed earnings for which no deferred taxes have been provided was approximately $14.0 million and $14.3 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 FASB guidelines.

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. The United States Internal Revenue Service (“IRS”) is in the process of conducting an audit of the Company’s United States Federal income tax returns for fiscal years 2009, 2008 and 2007. Management believes that the outcome of such audit will not have a material effect on the Company’s financial position, results of operations or cash flows.

Effective October 1, 2007, the Company adopted the provisions of the FASB guidance for accounting for uncertainty in income taxes. At the time of adoption, the uncertain tax position did not materially differ from the Company’s liability of $43,520. The amount of unrecognized tax liability with respect to the Company’s uncertain tax positions increased based on activities during the fiscal year. The Company classifies interest and penalties associated with the payment of income taxes in the Other Income (Expense) section of its consolidated statement of operations. Tax return filings, which are subject to review by local tax authorities by major jurisdiction, are as follows:

• United States—fiscal years ended September 2007, 2008, 2009 and 2010

• State of Texas—fiscal years ended September 2006, 2007, 2008, 2009 and 2010

• Russian Federation—calendar years 2007, 2008, 2009 and 2010

• Canada—fiscal years ended September 2006, 2007, 2008, 2009 and 2010

Notes to Consolidated Financial Statements—(Continued)

The following table is a reconciliation of the total amounts of unrecognized tax benefits at the beginning and end of fiscal year 2010 (in thousands):

<table><tr><td>Balance at October 1, 2007</td><td>$ 44</td></tr><tr><td>Change in prior year tax positions</td><td>115</td></tr><tr><td>Current tax positions</td><td>40</td></tr><tr><td>Lapse of statute of limitations</td><td>(7)</td></tr><tr><td>Balance at September 30, 2008</td><td>192</td></tr><tr><td>Change in prior year tax positions</td><td>26</td></tr><tr><td>Current tax positions</td><td>23</td></tr><tr><td>Lapse of statute of limitations</td><td>—</td></tr><tr><td>Balance at September 30, 2009</td><td>241</td></tr><tr><td>Change in prior year tax positions</td><td>(73)</td></tr><tr><td>Current tax positions</td><td>77</td></tr><tr><td>Lapse of statute of limitations</td><td>(25)</td></tr><tr><td>Balance at September 30, 2010</td><td>$220</td></tr></table>

The unrecognized tax benefits would affect the Company’s effective tax rate in future periods if they are favorably resolved.

Management believes that adequate provisions for income taxes have been reflected in the financial statements and is not aware of any significant exposure items that have not been reflected in the financial statements. Amounts considered probable of settlement within one year have been included in the accrued expenses and other liabilities in the accompanying consolidated balance sheet.

## 11. 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.



## OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

The following table summarizes the calculation of weighted average common shares and common equivalent shares outstanding for purposes of basic and diluted earnings per share (in thousands, except share and per share amounts):

<table><tr><td rowspan="2"></td><td colspan="4">YEAR ENDED SEPTEMBER 30,</td></tr><tr><td>2010</td><td>2009</td><td>2008</td><td></td></tr><tr><td>Net income</td><td>$ 14,082</td><td>$ 1,760</td><td>$ 14,152</td><td></td></tr><tr><td>Weighted average common shares and common share equivalents:</td><td></td><td></td><td></td><td></td></tr><tr><td>Common shares</td><td>6,031,314</td><td>5,950,403</td><td>5,908,727</td><td></td></tr><tr><td>Common share equivalents</td><td>161,704</td><td>128,975</td><td>207,312</td><td></td></tr><tr><td>Total weighted average common shares and common share equivalents</td><td>6,193,018</td><td>6,079,378</td><td>6,116,039</td><td></td></tr><tr><td>Earnings per share:</td><td></td><td></td><td></td><td></td></tr><tr><td>Basic</td><td>$ 2.33</td><td>$ 0.30</td><td>$ 2.40</td><td></td></tr><tr><td>Diluted</td><td>$ 2.27</td><td>$ 0.29</td><td>$ 2.31</td><td></td></tr></table>

Options totaling 63,000, 13,200 and 9,450 shares of common stock in fiscal years 2010, 2009 and 2008 respectively, were not included in the calculation of weighted average shares for diluted earnings per share because their effects were antidilutive.

## 12. Related Party Transactions:

Sales to OYO Japan and other affiliated companies were approximately $0.8 million, $1.1 million and $0.8 million during fiscal years 2010, 2009 and 2008, respectively. Purchases of inventory from OYO Japan and other affiliated companies were approximately $0.1 million in each of fiscal years 2010, 2009 and 2008, respectively.

## 13. 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 $18,000, $0.1 million and $0.2 million during fiscal years 2010, 2009 and 2008, 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.

On July 8, 2009, the Company received a complaint filed in the United States District Court in Nevada alleging that the Geospace Seismic Recorder (“GSR”), the Company’s newly developed wireless data acquisition system, infringes upon a patent held by Ascend Geo, LLC (“Ascend”). The Company requested and was granted a change in venue to the United States District Court for the Southern District of Texas in Houston (the “Court”). In addition to monetary damages, Ascend requested a preliminary injunction against future sales by the Company of the GSR nodal system. The Company filed its response with the Court requesting that it deny Ascend’s request.



## OYO Geospace Corporation and Subsidiaries
Notes to Consolidated Financial Statements—(Continued)

for a preliminary injunction and, on November 4, 2009, the Court denied Ascend’s request for a preliminary injunction. The Company strongly believes that the GSR nodal system does not violate Ascend’s patent. The Company also strongly believes that Ascend’s patent is not valid and has petitioned the United States Patent and Trademark Office (“PTO”) to re-examine its validity. On November 12, 2009, the PTO found that substantial new questions of patentability were raised by the petition as to each of the claims of the Ascend patent and issued an office action rejecting each of the claims based on prior art that the Company submitted to the PTO. Based on the PTO’s initial finding of invalidity of Ascend’s patent claims, the Company petitioned the Court to stay the litigation until the PTO can complete its reexamination of Ascend’s patent. The Court accepted the Company’s request on December 11, 2009. On May 20, 2010, after full briefing from both Ascend and the Company, the PTO examiner found all claims to be invalid. On September 17, 2010, Ascend filed a notice of appeal to the Board of Patent Appeals and Interferences, and, so, the reexamination continues. According to Ascend’s website, it ceased business operations on July 15, 2010. The Company will continue to defend vigorously its right to build and sell its GSR products and based on developments to date, the Company believes that the matter will be resolved satisfactorily in its favor. The Company further believes that Ascend’s claims are without merit and intends to seek recovery of its attorney fees. At this time, however, the Company is unable to predict the outcome of its dispute regarding Ascend’s patent or Ascend’s claims.

## 14. Supplemental Cash Flow Information:

Supplemental cash flow information is as follows (in thousands):

## 15. Segment and Geographic Information:

The Company evaluates financial performance based on two business segments: Seismic and Thermal Solutions. The Seismic product lines currently consist of geophones and hydrophones, including multi-component geophones and hydrophones, seismic leader wire, geophone string connectors, seismic telemetry cables, high definition reservoir characterization products and services, marine seismic cable retrieval devices, data acquisition systems, offshore cables and industrial products. Thermal Solutions products include thermal printers, thermal printheads and dry thermal film and other media. The Company sells these products to a variety of markets, including the screen print, point of sale, signage and textile markets. The Company also sells these Thermal Solutions products to its seismic customers.

* The Company’s manufacturing operations for its Seismic and Thermal Solutions business segments are combined. Therefore, the Company does not segregate and report separate balance sheet accounts for these segments. As a result, the Company does not report business segment balance sheet information.

“Corporate” net sales consists of rental revenue earned from an operating lease of a surplus building located in Houston, Texas. “Corporate” loss from operations primarily consists of the Company’s Houston headquarter general and administrative expenses.
