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 subsidiaries. We design and manufacture instruments and equipment used in the acquisition and processing of seismic data as well as in the characterization and monitoring of producing oil and gas reservoirs. We have been in the seismic instrument and equipment business since 1980 and market our products primarily to the oil and gas industry. We also design, manufacture and distribute thermal imaging equipment, and dry thermal film products targeted at the screen print, point of sale, signage and textile market sectors. We have been manufacturing thermal imaging products since 1995. We report and evaluate financial information for each of these two segments: Seismic and Thermal Solutions.

Seismic Products

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

Seismic Exploration Products

Seismic data acquisition is conducted by combining a seismic energy source and a seismic data recording system. We provide many of the components of data recording systems, including geophones, hydrophones, multi-component sensors, seismic leader wire, geophone strings, connectors, seismic telemetry cables and other seismic related products. We also design and manufacture specialized seismic data acquisition systems targeted at conventional and niche markets. On land, our customers use our 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. Additionally, we recently announced the development of a wireless seismic data acquisition system capable of very large channel configurations, which is expected to be commercially available in the first calendar quarter of 2008. 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 products are compatible with most major seismic data systems currently in use, and sales result primarily from seismic contractors purchasing our products as components of new seismic data systems or to repair and replace components of seismic data systems already in use.

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

Seismic Reservoir Products

We have developed permanently installed high-definition reservoir characterization products for ocean-bottom applications in producing oil and gas fields. We also produce a retrievable version of this ocean-bottom system for use on fields where permanently installed systems are not appropriate or economical. Seismic surveys

2

repeated over selected time intervals show dynamic changes within the reservoir and can be used to monitor the effects of production. Utilizing these products, producers can enhance the recovery of oil and gas deposits over the life of a reservoir.

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

Emerging Technology Products

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

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

Thermal Solution Products

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

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

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

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

As a result of the bankruptcy filing by the Former Primary Film Supplier, we recorded a $1.2 million charge in fiscal year 2002 due to the ultimate uncertainty of realization of value on certain assets, particularly certain

3

prepaid purchase benefits and other benefits under the amended supply contract with the Former Primary Film Supplier. At the time, we believed there had not been any impairment in the value of the intellectual property we acquired from the Former Primary Film Supplier because we utilized such property to manufacture dry thermal film.

On December 10, 2002, we received a notice of claim, in connection with the Former Primary Film Supplier’s bankruptcy, for alleged preferential payments made by the Former Primary Film Supplier to us in the period before the bankruptcy proceeding in the approximate amount of $259,000. On July 7, 2004, an amended claim was filed against us and the amount of the alleged preferential payments made by the Former Primary Film Supplier was increased to approximately $895,000. On January 20, 2006, a motion to amend was filed regarding the claims pending against us. On August 28, 2006, the motion to amend was denied.

On March 8, 2007, we entered into a court-approved settlement agreement with the trustee of the bankruptcy estate pursuant to which we paid $95,000 to the bankruptcy estate in full settlement of the claims for preferential payments as described above. Our general unsecured claim as a creditor of the Former Primary Film Supplier has been increased to include this $95,000 payment. The settlement agreement also provided for the full release of any claims by the bankruptcy estate against us. We are unable at this time to predict the outcome and effects of our claim as a creditor.

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

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

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

Products and Product Development

Seismic Products

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

4

compatible with most major seismic data acquisition systems currently in use. We believe that our seismic products are among the most technologically advanced instruments and equipment available for seismic data acquisition.

Our products used in marine seismic data acquisition include our patented marine seismic streamer retrieval devices (“SRDs”). Occasionally, 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.

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

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

Our recent 3D seismic product developments include an omni-directional geophone for use in reservoir monitoring, a compact marine three-component or four-component gimbaled sensor and special-purpose connectors, connector arrays and cases. We recently announced the development of a wireless seismic data acquisition system capable of very large channel configurations, which is expected to be commercially available in the first calendar quarter of 2008.

In order to take advantage of our existing cable manufacturing facilities and capabilities in Houston, we are designing and selling new 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 our Houston facility to manufacture deepwater reservoir characterization products. We are aggressively working to diversify our seismic product lines as well as utilizing our manufacturing capabilities for uses in other industries.

Thermal Solutions Products

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

5

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 geophones, hydrophones, geophone string connectors, leader wire and telemetry cable are ION (formerly Input/Output), SERCEL (a division of CGG/Veritas) and Steward Cable. Furthermore, entities in China affiliated with SERCEL, as well as other Chinese manufacturers, produce geophones having similar design and specifications as one of our older geophone models. The Chinese entity affiliated with SERCEL has recently started producing a lower-cost geophone meeting current industry standards and specifications.

We believe that the principal key for success in the seismic instruments and equipment market are technological superiority, product durability, reliability, and customer support. We believe that price and product delivery are always important considerations for our customers. In general, most customers prefer to standardize 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 an outside geophone or hydrophone manufacturer 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.

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 traditional seismic equipment manufacturers or equipment providers such as WesternGeco (Schlumberger), ION, SERCEL and some newly formed alliances involving these companies.

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

Thermal Solutions Products

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

Suppliers

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

6

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, 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 12.6% of the fiscal year 2007 revenues. None of our customers comprised more than 10% of our net sales for fiscal years 2006 or 2005. The following table describes our sales by customer type (in thousands):

	YEAR ENDED SEPTEMBER 30,
	2007		2006		2005
Seismic exploration customers	$	83,193	$	59,622	$	47,437

Other		344		37		—
	$	138,106	$	103,700	$	72,823

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 2012. Our dry thermal film technology patents expire at varying dates beginning in 2013.

Research and Development

We expect to incur significant future research and development expenditures aimed at the development of additional seismic data acquisition products to be used for high-definition reservoir characterization in both land and marine environments and thermal imaging technologies. We have incurred company-sponsored research and development expenses of $7.3 million, $6.6 million and $5.0 million during the fiscal years ended September 30, 2007, 2006 and 2005, respectively.

7

Employees

As of September 30, 2007, we employed approximately 1,169 people predominantly on a full-time basis, of which approximately 545 were employed in the United States and approximately 575 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. Historically, the markets for oil and gas have been volatile, and those markets are likely to continue to be volatile. Oil and gas prices are subject to wide fluctuation in response to changes in the supply of and demand for oil and gas, market uncertainty and a variety of additional factors that are beyond our control. These factors include the level of consumer demand, weather conditions, domestic and foreign governmental regulations, price and availability of alternative fuels, political conditions and hostilities in the Middle East and other significant oil-producing regions, increases and decreases in foreign supply of oil and gas, prices of foreign imports and overall economic conditions. Any unexpected material changes in oil and gas prices or other market trends that adversely impacts seismic exploration activity would likely affect the demand for our products and could materially and adversely affect our results of operations and liquidity.

Our New Products May Not Achieve Market Acceptance

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

8

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 4.1 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, 2007 averaged approximately 57,000 shares, which is relatively small, though higher than in prior years due to the sale by OYO Corporation, through OYO Corporation U.S.A., of 1,700,000 shares of our common stock during fiscal years 2006 and 2005. Our small float and daily trading volumes have in the past caused, and may in the future result in, significant volatility in our stock price.

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

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

Our Industry Is Characterized By Rapid Technological Development and Product Obsolescence

Our instruments and equipment in both of our business segments are constantly undergoing rapid technological improvement. Our future success depends on our ability to continue to:

• improve our existing product lines,

• address the increasingly sophisticated needs of our customers,

• maintain a reputation for technological leadership,

• maintain market acceptance of our products,

• 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.

9

We Operate in Highly Competitive Markets

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

As to our thermal solutions products, we compete with other printing solutions, including inkjet and laser printing technologies, many of which are provided by large companies with significant resources.

We cannot assure you that sales of our products will continue at current volumes or prices if current competitors or new market entrants introduce new products with better features, performance, price or other characteristics than our products. Competitive pressures or other factors 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 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 67.3% of our net sales during fiscal year 2007; however, we believe the percentage is much higher as goods are 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 2008 and subsequent years. Substantially all of our sales from the United States are made in U.S. dollars, though from time to time we make sales in foreign currencies. As a result, we may be subject to foreign currency fluctuations on our sales. In addition, net assets reflected on the balance sheets of our Russian, Canadian and United Kingdom subsidiaries are booked in foreign currencies and are subject to currency fluctuations. Consequently, significant foreign currency fluctuations could adversely impact our results of operations.

Foreign sales are subject to special risks inherent in doing business outside of the U.S., including the risk of war, terrorist activities, civil disturbances, embargo and government activities and foreign attitudes about

10

conducting business activities with the U.S., all of which may disrupt markets. A portion of our manufacturing is conducted through our subsidiary OYO-GEO Impulse, which is based in 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 United States government approval in the form of an export license. We cannot assure you that we will not experience difficulties in connection with future foreign sales. Also due to foreign laws and restrictions, should we experience substantial growth in certain foreign markets, for example in the Russian Federation, we may not be able to transfer cash balances to the United States to assist with debt servicing or other obligations.

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, 2007, approximately 20% of our consolidated revenues related to 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

In August 2005, our single largest stockholder, OYO Corporation, a Japanese corporation, through its wholly owned subsidiary, OYO Corporation U.S.A., sold 1,400,000 shares of our common stock in a secondary offering. During fiscal year 2006, pursuant to a privately negotiated transaction, OYO Corporation U.S.A. transferred 300,000 shares of our common stock to a former director upon the exercise of stock options held by such director who in turn sold the shares to non-affiliates. At September 30, 2007, OYO Corporation owned indirectly in the aggregate approximately 20.2% of our common stock. Accordingly, OYO Corporation, through its wholly owned subsidiary OYO Corporation U.S.A., is able to exercise substantial influence over our management, operations and affairs. In addition, we currently have, and may continue to have, a variety of contractual relationships with OYO Corporation and its affiliates. These relationships could further enable OYO Corporation to indirectly exert substantial influence on our operations.

Our Success Depends Upon a Limited Number of Key Personnel

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

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

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

Sarbanes-Oxley Act of 2002

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

With respect to the internal controls requirement flowing from the Act, we have devoted substantial efforts and incurred significant expenses in fiscal years 2005, 2006 and 2007 in documenting, testing and remediating potential deficiencies in our internal controls system. We have added internal resources and hired outside experts to help us with respect to these matters. We expect to incur substantial expenses in the future to maintain and audit our internal control documentation and procedures.

Item 2. Properties

As of September 30, 2007, our operations included the following locations:

Location	Owned/Leased	Approximate Square Footage	Use
Houston, Texas	Owned	387,000	See Note 1 below
Houston, Texas	Owned	77,000	See Note 2 below
Ufa, Bashkortostan, Russia	Owned	120,000	Manufacturing
Ufa, Bashkortostan, Russia	Owned	41,000	See Note 3 below
Calgary, Alberta, Canada	Owned	45,000	Sales and service
Luton, Bedfordshire, England	Owned	8,000	Sales and service
Beijing, China	Leased	1,000	Sales and service

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

(1) This property is located at 7007 Pinemont Drive in Houston, Texas (the “Pinemont facility”). It was purchased in September 2003 for the purpose of consolidating into one location all manufacturing, engineering, selling, marketing and administrative activities for both the seismic and thermal solution segment of our company in the United States. The Pinemont facility also serves as our company headquarters. Due to capacity constraints and growth expectations, we added 130,000 sq. ft. of manufacturing space and 40,000 sq. ft. of office space. We began utilizing this additional space in the fourth quarter of fiscal year 2007.

(2) This property, located at 7334 N. Gessner in Houston, Texas (the “Gessner facility”), previously contained a manufacturing operation and certain support functions. We completed the relocation of these operations to the Pinemont facility in February 2004. In February 2006, we entered into a seven-year lease with a tenant whereby the tenant agreed to lease portions of the building until March 2008, at which time the tenant will occupy the entire Gessner facility.

(3) This property served as a location for manufacturing operations until October 2002, at which time these operations were relocated to the new 120,000 square foot building in Ufa noted above. During the fiscal year ended September 30, 2007, we completed the sale of approximately 70% of this property and expect to complete the sale of the remaining approximately 30% during the fiscal year ending September 30, 2008. The sale of the 70% portion of the property resulted in a pretax gain of $1.7 million.

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 September 28, 2007, Beijing JMT Science & Technology, Ltd., filed a lawsuit against Geospace Technologies, LP, OYOG, LLC, OYO Geospace Corporation, OYO Corporation U.S.A. and Geospace Engineering Resources International, LP in the State District Court of Harris County, Texas, alleging claims in quantum meruit, breach of contract, fraud and theft of service related to commission payments allegedly owed to the plaintiff. The plaintiff is seeking damages in the amount of $490,000 plus interest, fees, expenses and any other actual or punitive damages. The Company intends to defend vigorously against the plaintiff’s claims. The ultimate liability with respect to these claims cannot be determined at this time.

Other than the aforementioned lawsuit, we are not aware of any current or pending litigation or proceedings that could have a material adverse effect on our results of operations, cash flows or financial condition, although we continue to monitor developments in the bankruptcy proceeding by our Former Primary Film Supplier and its existing claim against us as is described in the section entitled “Business—Thermal Solutions Products” contained in this Annual Report on Form 10-K.

Item 4. Submission of Matters to Vote of Security Holders

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

The following is management’s discussion and analysis of the major elements of our consolidated financial statements. You should read this discussion and analysis together with our consolidated financial statements, including the accompanying notes, and other detailed information appearing elsewhere in this Form 10-K, included under the heading “Risk Factors”. The discussion of our financial condition and results of operations includes various forward-looking statements about our markets, the demand for our products and services and our future plans and results. These statements are based on assumptions that we consider to be reasonable, but that could prove to be incorrect. For more information regarding our assumptions, you should refer to the section entitled “—Forward-Looking Statements and Assumptions” contained in this Item 7 in this 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 dry thermal film products targeted at the screen print, point of sale, signage and textile market sectors. We have been manufacturing thermal imaging products in what is called our Thermal Solutions segment since 1995. For a more detailed discussion of our business segments and products, see the information under the heading “Business” in this Annual Report on Form 10-K.

Consolidated Results of Operations

We experienced strong worldwide demand for our seismic products throughout fiscal year 2007. Demand was strong in both our seismic exploration and seismic reservoir products and across most of our international markets, although we saw some decline in our year-over-year backlog for these products primarily due to the delivery of a $16.2 million seabed reservoir characterization system in our first quarter of fiscal year 2007. Our quarterly results throughout fiscal year 2007 were significantly impacted by the sale of this reservoir characterization system, as well as other reservoir characterization products. These reservoir characterization products generally have higher profit margins than our traditional seismic exploration products, and the sales price for systems sold during fiscal year 2007 ranged from approximately $1.0 million to $16.2 million.

Our reservoir characterization products have been well-received by the marketplace and we are pleased with the increasing acceptance of both our seabed and borehole suites of reservoir imaging products. However, 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 these reservoir characterization products in our backlog, although, we are optimistic about a number of on-going negotiations with customers concerning these products. We cannot now determine what impact, if any, these potential orders may have on our future quarterly financial results. 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 or accepted, the exact timing of any future sales can dramatically affect our quarterly results.

Overview

Fiscal Year 2007 Compared to Fiscal Year 2006

Consolidated net sales for the year ended September 30, 2007 increased $34.4 million, or 33.2%, from fiscal year 2006. The increase in sales reflects strong demand from customers for our seismic exploration and seismic reservoir products as exploration activities increased due to higher oil and gas commodity prices.

Consolidated gross profits for the year ended September 30, 2007 increased by $14.2 million, or 39.3%, from fiscal year 2006. The increase in gross profits resulted primarily from increased sales of all products, including increased sales of our seismic reservoir, which have higher gross profit margins.

Consolidated operating expenses for the year ended September 30, 2007 increased $2.3 million, or 10.6%, from fiscal year 2006. The increase in operating expenses primarily resulted from increased incentive compensation expense, research and development expenses and other cost increases consistent with the increase in net sales.

Included in our fiscal year 2007 operating income is a $1.7 million gain from the sale of a significant portion of a surplus property located in the Russian Federation.

The U.S. statutory rate applicable to us for the periods reported was 34.0%; however, our effective tax rate was 30.6% and 31.4%, for the years ended September 30, 2007 and 2006, respectively. These lower effective tax rates included tax benefits resulting from (i) lower tax rates applicable to income earned in foreign jurisdictions, (ii) extraterritorial income deductions applicable to foreign export sales reported through December 31, 2006, (iii) manufacturers’/producers’ deduction, and (iv) research and experimentation tax credits.

Fiscal Year 2006 Compared to Fiscal Year 2005

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

18

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

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

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

Segment Results of Operations

Seismic Products

Fiscal Year 2007 Compared to Fiscal Year 2006

Net Sales. Sales of our seismic products for fiscal year 2007 increased $34.0 million, or 38.4%, from fiscal year 2006. All product groups contributed to the increase in sales, including a $23.6 million increase in seismic exploration product sales and an $8.9 million increase in seismic reservoir characterization product sales. These sales increases resulted from increasing worldwide oil and gas exploration activities creating higher demand for our seismic exploration products, and from increasing demand and acceptance by customers for our reservoir characterization product technologies. Our reservoir characterization products generally yield higher gross margins than do our other seismic exploration products. Our industrial products, including offshore cables, industrial cables and industrial sensors also generated higher revenues during fiscal year 2007.

Operating Income. Operating income from sales of our seismic products for fiscal year 2007 increased $13.6 million, or 60.8%, from fiscal year 2006. Our operating income increased in fiscal year 2007 due to increased sales of our seismic products, and from a greater mix of reservoir characterization products which yield higher profit margins.

Fiscal Year 2006 Compared to Fiscal Year 2005

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

Operating Income. Operating income from sales of our seismic products for fiscal year 2006 increased $12.2 million, or 121.5%, from fiscal year 2005. Our operating income increased in fiscal year 2006 due to increased sales and from a greater mix of high profit margin product sales including reservoir characterization products and marine-based exploration products.

19

Thermal Solutions Products

Fiscal Year 2007 Compared to Fiscal Year 2006

Net Sales. Sales of our thermal solutions products for fiscal year 2007 increased $0.1 million, or 0.8%, from fiscal year 2006. This increase in sales resulted from a small increase in equipment sales offset by a decline in sales of thermal film products. In addition, approximately 30% of our thermal solutions sales originate in Europe and such transactions are conducted in the local applicable currency. The strengthening of these currencies against the U.S. dollar during fiscal year 2007 has contributed to the increase in consolidated sales for this business segment.

Operating Income. Our operating income from our thermal solutions products for fiscal year 2007 increased $67,000, or 12.2%, from fiscal year 2006. Such increase in operating income is the result of increased sales, foreign currency impact on profits recorded by our European subsidiary, and manufacturing process improvements.

Fiscal Year 2006 Compared to Fiscal Year 2005

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

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

Recent Acquisitions

OYO-GEO Impulse International, LLC

At September 30, 2005, we owned a 97% interest in OYO-GEO Impulse. In October 2005, we purchased for $0.1 million the remaining 3% ownership interest in this entity from the minority shareholder. OYO-GEO Impulse is now a wholly-owned subsidiary of the Company. OYO-GEO Impulse manufactures international-standard geophone sensors and related seismic products for the Russian and international seismic marketplaces.

For a discussion regarding our acquisition of assets from Graphtec and acquisition of intellectual property from our Former Primary Film Supplier see “Business—Thermal Solution Products” in this Annual Report on Form 10-K.

Facilities Expansion

We have been running at or near full capacity in portions of our original Pinemont facility. As a result, in fiscal year 2006 we opted to expand our Pinemont facility manufacturing space to approximately double its original size. We have completed the construction phase of this facility expansion, and are now in the process of adding and assembling the appropriate manufacturing machinery and equipment. We have begun producing some products in this facility, although not in significant quantities. The total cost of this facility expansion, including initial machinery and equipment purchases, is expected to be $12.0 million. Costs for the facility expansion and machinery and equipment are being funded from our internal cash flows and/or from borrowings under our Credit Agreement, discussed below under the heading “—Liquidity and Capital Resources”. Depending on our future cash flow needs, we may obtain a long-term loan secured by a mortgage on our Pinemont facility to replenish our cash reserves and/or repay borrowings under our Credit Agreement.

As a result of growth in our Russian operation, and with an expectation of new product lines to be introduced over the coming years, we are evaluating plans to expand our manufacturing capacity in the Russian Federation, including the construction of added capacity onto our existing 120,000 square foot facility. We are still in the early phases of planning for this project and considering the various options available to us. The

20

construction or acquisition of any additional space is estimated to cost up to $6.0 million. The Russian facility expansion is expected to be financed from (i) our internal cash flows, (ii) the sale of non-critical assets, and/or (iii) from borrowings under our Credit Agreement, discussed below under the heading “—Liquidity and Capital Resources”.

Incentive Compensation Program

Our incentive compensation program for fiscal year 2007 allows most employees to begin earning incentive compensation upon the company exceeding a 5% pretax return on shareholders’ equity (determined as of September 30, 2006). In addition, certain key employees are also required to achieve specific goals to earn a significant portion of their incentive compensation award. Bonus awards earned under the program are paid out to eligible employees after the end of the fiscal year.

Upon reaching the 5% threshold under this program, an incentive compensation accrual is established equal to 30% of the amount of any consolidated pretax profits above the 5% pretax return threshold. The maximum aggregate bonus under the program for fiscal year 2007 is $3.2 million. As a result of the significant pretax profits earned by the company during the three months ended December 31, 2006 and upon the expectation that key employees will achieve their goals, we accrued incentive compensation expenses of $3.2 million during our first quarter of fiscal year 2007, which is the maximum amount allowed under the program. As a result, there were no additional incentive compensation expenses recorded since the first fiscal quarter ended December 31, 2006. Under a similar incentive compensation program for fiscal year 2006, we accrued incentive compensation expenses of $3.0 million.

Liquidity and Capital Resources

At September 30, 2007, we had $3.0 million in cash and cash equivalents. For fiscal year 2007, we generated approximately $12.4 million of cash in operating activities. The cash generated in operating activities primarily resulted from net income of $19.6 million, which includes non-cash charges of $3.5 million for deferred taxes, stock-based compensation, depreciation and amortization. Other sources of cash from operating activities and changes in our working capital accounts included (i) a $2.5 million increase in accrued expenses and other primarily due to increased accrual for unpaid incentive compensation and product warranty expense, (ii) a $1.7 million additional reserve for bad debts and inventory obsolescence and (iii) a $1.2 million increase in accounts payable primarily resulting from increased levels of inventories and fixed assets. These sources of cash were partially offset by (i) a $7.7 million decrease in deferred revenue resulting from the recognition of revenue of a large reservoir characterization system in our first quarter, (ii) a $2.3 million increase in inventories resulting from new and anticipated customer orders, and (iii) a $3.3 million increase in accounts and notes receivable resulting from increased sales. As previously noted, we have been in a period of significant demand for our products, which has resulted in a build-up of our inventories to be able to continue to meet actual and anticipated future customer demand. Such increases in our inventory levels have likewise resulted in increases in our inventory obsolescence expense as the level of obsolete and slow moving inventories increase. The increased level of inventories has put greater demands on our management of inventories, and we are giving substantial attention to the management of our inventories in this context.

For fiscal year 2007, we used approximately $15.1 million of cash in investing activities, including $17.0 million for capital expenditures, which was partially offset by $1.9 million of cash proceeds from the sale of property and equipment, primarily from the sale of a portion of a surplus property located in the Russian Federation. We estimate that our total capital expenditures in fiscal year 2008 will be approximately $16.0 million to $22.0 million, which includes capital expenditures to (i) expand our facility in the Russian Federation, (ii) complete our equipment additions at our recently expanded facility in Houston, (iii) increase the size of our seismic equipment rental fleet, and (iv) improve software and other technologies in our worldwide facilities. We expect the capital expenditures will be financed from our internal cash flow and/or from borrowings under our Credit Agreement.

21

For fiscal year 2007, we generated approximately $2.7 million of cash in the financing activities of our operations, including a $3.1 million excess tax benefit from stock-based compensation and $2.5 million received from the exercise of stock options by employees and directors. These sources of cash were partially offset by $2.3 million of net principal payments under our Credit Agreement.

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

For fiscal year 2006, we used approximately $4.6 million of cash in investing activities, including $4.8 million for capital expenditures, which was partially offset by $0.3 million of cash proceeds we received from the sale of surplus land.

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

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

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

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

On November 22, 2004, several of our subsidiaries entered into a credit agreement (the “Credit Agreement”) with a bank. Under the Credit Agreement, as amended, our borrower subsidiaries can borrow up to $25.0 million principally secured by their accounts, inventories and equipment. The Credit Agreement expires on January 31, 2010. The Credit Agreement limits the incurrence of additional indebtedness, requires the maintenance of certain financial ratios, restricts our and our borrower subsidiaries’ ability to pay dividends and contains other covenants customary in agreements of this type. We believe that the ratio of total liabilities to tangible net worth and the asset coverage ratio could prove to be the most restrictive. The interest rate for borrowings under the Credit Agreement is, at our borrower subsidiaries’ option, a discounted prime rate or a LIBOR based rate. At September 30, 2007, there were borrowings of $0.9 million under the Credit Agreement, $0.5 million of standby letters of credit were outstanding and additional available borrowings of $23.6 million.

22

A summary of future payments owed for contractual obligations and commercial commitments as of September 30, 2007 are shown in the table below (in thousands):

	Payment Due By Period
	Total		Less Than 1 Year		1 – 3 Years		3 – 5 Years		After 5 Years
Contractual Obligations:
Long-term debt	$	4,545	$	322	$	3,103	$	640	$	480
Commercial Commitments:
Lines of Credit		924		—		924		—		—
Total Contractual Obligations and Commercial Commitments	$	5,469	$	322	$	4,027	$	640	$	480

We believe that the combination of existing cash reserves, cash flows from operations and borrowing availability under the Credit Agreement should provide us sufficient capital resources and liquidity to fund our planned operations through fiscal year 2008. However, there can be no assurance that such sources of capital will be sufficient to support our capital requirements in the long-term, and we may be required to issue additional debt or equity securities in the future to meet our capital requirements. There can be no assurance we would be able to issue additional equity or debt securities in the future on terms that are acceptable to us or at all.

Off-Balance Sheet Arrangements

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

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the use of estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We consider many factors in selecting appropriate operational and financial accounting policies and controls, and in developing the estimates and assumptions that are used in the preparation of these financial statements. We continually evaluate our estimates, including those related to bad debt reserves, inventory obsolescence reserves, self-insurance reserves 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 that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different conditions or assumptions.

Goodwill represents the excess of the purchase price of purchased businesses over the estimated fair value of the acquired business’ net assets. Under the Statement of Financial Accounting Standards, or “SFAS”, 142 “Goodwill and Other Intangible Assets” (“SFAS 142”), goodwill and intangible assets with indefinite lives are no longer amortized but are reviewed periodically for impairment. Intangible assets that are not deemed to have indefinite lives will continue to be amortized over their useful lives; however, no maximum life applies. In accordance with the provisions of SFAS 142, we no longer record goodwill amortization expense. We review the carrying value of goodwill and other long-lived assets to determine whether there has been an impairment since the date of the relevant acquisition. We have elected to make September 30 the annual impairment assessment date and will perform additional impairment tests if a change in circumstances occurs that would more likely than not reduce the fair value of long-lived assets below their carrying amount. The assessment is performed in two steps: step one is to test for potential impairment and if potential losses are identified, step two is to measure the impairment loss. We performed step one at September 30, 2007 and found that there were no impairments at that time; thus, step two was not necessary.

23

We primarily derive revenue from the sale, and short-term rental under operating leases, of seismic instruments and equipment and thermal solutions products. We generally recognize sales revenues when our products are shipped and title and risk of loss have passed to the customer. We recognize rental revenues as earned over the rental period. Rentals of our equipment generally range from daily rentals to rental periods of up to 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 is 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 obligating us to repair or replace equipment with manufacturing defects. We maintain a reserve for future warranty costs based on historical experience or, in the absence of historical experience, management estimates. We record a write-down of inventory when the cost basis of any item (including any estimated future costs to complete the manufacturing process) exceeds its net realizable value.

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

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

• Delivery has occurred or services have been rendered. For product sales, we do not recognize revenues until delivery has occurred or performance 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 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, 2007, we had no sales under bill and hold arrangements.

Recent Accounting Pronouncements

In May 2005, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 154 “Accounting Changes and Error Corrections—a replacement of APB Opinion No. 20 and FASB Statement No. 3” (“SFAS No. 154”). SFAS No. 154 requires retrospective application to prior periods’ financial statements for changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle should be recognized in the period of the accounting change. SFAS No. 154 also requires that a change in depreciation, amortization, or depletion method for long-lived non-financial assets be accounted for as a change in accounting estimate affected by a change in accounting principle. SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. We adopted the provisions of SFAS No. 154 as of October 1, 2006. The adoption of SFAS No. 154 did not have a material effect on our consolidated financial statements.

In June 2006, the FASB issued Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109, to clarify certain aspects of accounting for uncertain tax position, including issues related to the recognition and measurement of those tax positions. This interpretation is effective for fiscal years beginning after December 15, 2006, and therefore will apply to us with our 2008 fiscal year beginning October 1, 2007. We are in the process of evaluating the impact of this interpretation.

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

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”), which provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. The guidance is applicable for fiscal years ending after November 15, 2006. We adopted the provisions of SAB 108 as of September 30, 2007. The adoption of SAB 108 did not have a material effect on our consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an Amendment of FASB Statement No. 115” (“SFAS No. 159”). SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings at each subsequent reporting date. SFAS No. 159 is effective for the first fiscal year beginning after November 15, 2006, and therefore will apply with our 2008 fiscal year beginning October 1, 2007. We are evaluating the impact, if any, that the adoption of SFAS No. 159 will have on our consolidated financial statements.

Forward-Looking Statements and Assumptions

This Report on Form 10-K and the documents incorporated by reference herein, if any, contain “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. You can identify these forward-looking statements by terminology such as “may”, “will”, “should”, “intend”, “expect”, “plan”, “budget”, “forecast”, “anticipate”, “believe”, “estimate”, “predict”, “potential”, “continue” or similar words. You should read statements that contain these words carefully because they discuss our future expectations, contain projections of our future results of operations or of our financial position or state other forward-looking information. These forward-looking statements reflect our best judgment about future events and trends based on the information

25

currently available to us. However, there may be events in the future that we are not able to predict or control. The factors listed under the caption “Risk Factors”, as well as cautionary language in this Annual Report on Form 10-K, provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. You should be aware that the occurrence of the events described in these risk factors and elsewhere in this Annual Report on Form 10-K could have a material adverse effect on our business, results of operations and financial position, and actual events and results of operations may vary materially from our current expectations.

Management’s Current Outlook and Assumptions

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

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

• While demand for our traditional seismic exploration products is cyclical, we believe demand for these products will continue to be strong through fiscal year 2008 as a result of high oil and gas commodity prices. However, we expect intense competition and pricing pressures to continue to impact the gross profit margins we realize on most of our seismic exploration products.

• Based on the level of existing customer orders and inquiries, we expect revenues from our borehole and seabed reservoir characterization products to be similar to or greater than fiscal year 2007 levels.

• We expect new products introductions, such as our new wireless seismic data recording system, to significantly impact our revenues and profits during fiscal year 2008.

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

• As our offshore cable and industrial sensor products gain market acceptance, we expect demand for these products to increase.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The following discussion of our exposure to various market risks contains “forward looking statements” that involve risks and uncertainties. These projected results have been prepared utilizing certain assumptions considered reasonable in light of information currently available to us. Nevertheless, because of the inherent unpredictability of foreign currency rates and interest rates, as well as other factors, actual results could differ materially from those projected in this forward looking information.

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 for purposes other than trading purposes. Further, we do not engage in commodity or commodity derivative instrument purchasing or selling transactions.

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, 2007 reflected approximately $5.3 million of net working capital related to OYO-GEO Impulse.

26

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, 2007, the foreign exchange rate of the U.S. dollar to the ruble was 1:24.9. 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, 2007, we had outstanding accounts and notes receivable of $0.7 million and $0.3 million from our subsidiaries in the Russian Federation and Canada, respectively. At September 30, 2007, the foreign exchange rate of the U.S. dollar to ruble was 1:24.9. If the U.S. dollar versus ruble exchange rate were to decline by ten percent our intercompany notes receivable could decline by $72,000. Due to the relatively small amount of intercompany receivables due from our subsidiary in Canada changes in the exchange rate would not have a material effect.

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, our borrowing interest rate is a discounted prime lending rate or a LIBOR based rate, whichever we select. Under the real estate mortgage agreement, our borrowing rate is a LIBOR based rate plus 159 basis points with a minimum rate of 3.8%. As of September 30, 2007, we had borrowings of $0.9 million under the Credit Agreement and had standby letters of credit in the amount of $0.5 million outstanding at a borrowing rate of 6.4%. We also had borrowings of $2.6 million outstanding under our real estate mortgage agreement at a rate of 7.4%. Due to the amount of borrowings outstanding under these facilities, including potential borrowings available under the Credit Agreement, any increased interest costs associated with movements in market interest rates could be material to our financial condition, results of operations and/or cash flow. At September 30, 2007, based on our current level of borrowings, a 1.0% increase in interest rates would increase our interest expense annually by approximately $35,000.

Item 8. Financial Statements and Supplementary Data

Our consolidated financial statements, including the reports thereon, the notes thereto and supplementary data begin at page F-1 of this Form 10-K and are incorporated herein by reference.

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

As disclosed in our Current Report on Form 8-K dated December 7, 2006, filed with the Securities and Exchange Commission on December 12, 2006, on December 7, 2006, we notified PricewaterhouseCoopers L.L.P. (“PwC”), our independent registered public accounting firm, that our Audit Committee decided to dismiss PwC as our independent registered public accounting firm. During the fiscal years ended September 30, 2005 and

27

2006 and through December 7, 2006, there were no disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of PwC, would have caused PwC to make reference thereto in its reports on the financial statements for such years.

As further disclosed in our Current Report on Form 8-K dated December 7, 2006, filed with the Securities and Exchange Commission on December 12, 2006, our Audit Committee decided to engage UHY LLP (“UHY”) as our independent registered public accounting firm effective on December 7, 2006. UHY has acted as our independent registered public accounting firm beginning with the fiscal year ending September 30, 2007. Since December 7, 2006, UHY has not resigned, declined to stand for reelection or been dismissed, and there has been no disagreement related to accounting principles, audit procedures or financial statement disclosure between us and UHY, and UHY continues to serve as our independent public accountant.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

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

In connection with the preparation of this Annual Report on Form 10-K, the Company carried out an evaluation under the supervision and with the participation of the Company’s management, including the CEO and CFO, as of September 30, 2007 of the effectiveness of the Company’s disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on that evaluation, the CEO and CFO concluded that our disclosure controls and procedures are effective in ensuring that all material information required to be filed in this annual report has been made known to them in a timely fashion.

In our Annual Report on Form 10-K for the fiscal year ended September 30, 2005, we disclosed that a material weakness existed in our controls over the year-end physical inventory. Specifically, as previously disclosed, the controls in place to ensure an accurate count and verify the existence of inventory at our Pinemont facility in Houston, Texas were not properly designed and thus, failed to detect counting errors and other inaccuracies prior to the posting of the physical inventory adjustments to the general ledger. Following the discovery of the material weakness, management implemented a number of measures described in our Annual Report on Form 10-K for the fiscal year ended September 30, 2005 to remedy the weakness. As a result of those measures, and as stated above, the CEO and CFO have determined that our disclosure controls and procedures for fiscal year 2007, including our control over the year-end physical inventory, are effective.

Management’s Report on Internal Control Over Financial Reporting

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

Our management assessed the effectiveness of our internal control over financial reporting as of September 30, 2007. 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, 2007, our internal control over financial reporting is effective based on those criteria.

Our internal control over financial reporting as of September 30, 2007 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 have been no changes in our internal control over financial reporting identified in connection with our management’s evaluation of such internal control that occurred during our fourth fiscal quarter ended September 30, 2007 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders

of OYO Geospace Corporation:

We have audited the accompanying consolidated balance sheet of OYO Geospace Corporation and subsidiaries (“the Company”) as of September 30, 2007, and the related consolidated statements of operations, stockholders’ equity and cash flows for the year then ended. Our audit 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 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 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 audit provides 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, 2007, and the consolidated results of their operations and their cash flows for the year then ended, 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, 2007, 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 7, 2007 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’s (“the Company”) internal control over financial reporting as of September 30, 2007, 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, 2007, 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 sheet of OYO Geospace Corporation and subsidiaries as of September 30, 2007, and the related consolidated statements of operations, stockholders’ equity and cash flows for the year then ended, and our report dated December 7, 2007, expressed an unqualified opinion on those consolidated financial statements.

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, 2007 OYO Corporation U.S.A. (“OYO USA”) owned approximately 20.2% 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.

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.

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

F-9

Notes to Consolidated Financial Statements—(Continued)

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, 2007, the Company had two customers that together made up 32% of the Company’s accounts receivable.

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, 2007 reflected approximately $5.3 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, 2007, this subsidiary received approximately $6.0 million of its income in U.S. dollars as a result of intercompany sales to the Company’s subsidiary located in the U.S. To the extent that transactions of this subsidiary are settled in rubles, a devaluation of the ruble versus the U.S. dollar could reduce any contribution from 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 inventory when the cost basis of any manufactured product, including any estimated future costs to complete the manufacturing process, exceeds its net realizable value. Inventories are stated at the lower of cost (as determined by the first-in, first-out method) or market value.

Prepaid Expenses and Other Current Assets

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

Property, Plant and Equipment and Rental Equipment

Property, plant and equipment and rental equipment are stated at cost. Depreciation expense is calculated using the straight-line method over the following estimated useful lives:

	Years
Rental equipment	3-5
Property, plant and equipment:
Machinery and equipment	3-15
Buildings and building improvements	10-50
Other	5-10

Expenditures for renewals and betterments are capitalized. The Company changed the estimated useful life of the buildings as a result of segregating capital expenditures to better reflect the life of groups of assets within the buildings. 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.

Notes to Consolidated Financial Statements—(Continued)

Patents

Patents are amortized over the legal life of the patent or the estimated useful life of the patent, whichever is shorter. Intellectual property was being amortized using the straight-line method over five years. Patent amortization expense was approximately $0.2 million during each of fiscal years 2007, 2006 and 2005. Intellectual property amortization expense was approximately $0.2 million during fiscal year 2007 and $0.5 million during each of fiscal years 2006 and 2005. Amortization expense is estimated to be approximately $0.2 million for each of the fiscal years ending September 30, 2008, 2009, 2010, 2011, and 2012, respectively.

Impairment of Long-lived Assets

The Company’s long-lived assets are reviewed for impairment whenever an event or change in circumstances indicates the carrying amount of an asset or group of assets may not be recoverable. The impairment review, if necessary, includes a comparison of expected future cash flows (undiscounted and without interest charges) to be generated by an asset group with the associated carrying value 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 more likely than not reduce the fair value of goodwill below its carrying amount. The assessment is performed in two steps: step one is to compare the carrying value of the 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 Company performed step one at September 30, 2007 and 2006 and found that there were no impairments at those times; thus, step two was not necessary.

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.

F-11

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

• 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 does not modify its normal billing and credit terms for these types of sales. As of September 30, 2007, there were no sales under bill and hold arrangements.

Deferred Revenue

Deferred revenue at September 30, 2006 represented progress payments related to the delivery of a reservoir characterization system. The system was recognized as revenue in the first quarter of fiscal 2007 upon delivery to the customer.

Research and Development Costs

The Company expenses research and development costs as incurred. Research and development costs include salaries, employee benefit costs, department supplies, direct project costs, and other related costs.

Product Warranties

The Company offers a standard product warranty obligating it to repair or replace products with 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):

Balance at the beginning of the period (October 1, 2005)	$	745
Accruals for warranties issued during the period		1,117
Accruals related to pre-existing warranties (including changes in estimates)		—
Settlements made (in cash or in kind) during the period		(1,173	)
Balance at the beginning of the period (October 1, 2006)		689
Accruals for warranties issued during the period		2,136
Accruals related to pre-existing warranties (including changes in estimates)		—
Settlements made (in cash or in kind) during the period		(1,714	)
Balance at the end of the period (September 30, 2007)	$	1,111

Stock-Based Compensation

In the first quarter of fiscal year 2006, the Company adopted Statement of Financial Accounting Standards (“SFAS 123R”), “Share-Based Payment”, which revises SFAS 123, “Accounting for Stock-Based Compensation”. The Company has elected to use the “modified prospective method” for existing grants which requires the Company to expense the unvested portion of these grants over the remaining vesting period. Additionally, grants made after adoption are to be valued and expensed over the applicable vesting period. The

F-12

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

Company uses the Black-Scholes model to value its new stock option grants under SFAS 123R. SFAS 123R also requires the Company to estimate forfeitures in calculating the expense related to stock-based compensation. In addition, SFAS 123R requires the Company to reflect the benefits of tax deductions in excess of recognized compensation cost to be reported as a financing cash inflow. As a result of the adoption of SFAS 123R, the Company recorded stock-based compensation expenses of $0.3 million and $0.6 million for the fiscal years ended September 30, 2007 and 2006.

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

	Year Ended September 30, 2005
Net income, as reported	$	2,507
Deduct: Total stock-based employee compensation expense determined under fair value method for all awards, net of related tax effects		(295	)
Pro forma net income	$	2,212
Earnings per share:
Basic-as reported	$	0.45
Basic-pro forma	$	0.39
Diluted-as reported	$	0.44
Diluted-pro forma	$	0.39

There were no stock options granted during fiscal year 2007. The fair value of options granted during the fiscal years ended September 30, 2006 and 2005 were estimated using the Black-Scholes option-pricing model using the following annualized data:

	2006		2005
Dividend yield rate	0	%	0	%
Risk-free interest rate	4.6	%	4.3	%
Expected volatility	56.0	%	55.0	%
Expected option term	6.25 years		5.0 years

Expected volatility was determined based on the historical volatility of the underlying shares over a period consistent with the expected term of the option. The expected term of the options granted in fiscal year 2006 was computed using the simplified method as described in Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin (“SAB”) No. 107, “Share-Based Payment”. Expected volatilities are based on the historical volatility of the Company’s stock and other factors.

Financial Instruments

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

F-13

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

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

Foreign Currency Gains and Losses

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

Derivatives

The Company records all derivatives on the balance sheet at fair value. Changes in derivative fair values will either be recognized in earnings as offsets to the changes in fair value of related hedged assets, liabilities and firm commitments or for forecasted transactions, deferred and recorded as a component of accumulated other comprehensive income until the hedged transactions occur and are recognized in earnings. The Company has, on occasion, attempted to hedge its currency exposure for significant purchase transactions denominated in foreign currencies. At September 30, 2007, the Company had no foreign currency forward contracts designed to hedge such currency exposures.

Shipping and Handling Costs

Amounts billed to a customer in a sales transaction related to reimbursable shipping and handling costs are included in revenues and the associated costs incurred by the Company for reimbursable shipping and handling costs are reported as an expense in cost of sales. The Company had shipping and handling costs of $0.7 million, $0.4 million and $0.4 million for each of the fiscal years ended September 30, 2007, 2006 and 2005.

Income Taxes

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

Recent Accounting Pronouncements

In May 2005, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 154 “Accounting Changes and Error Corrections—a replacement of APB Opinion No. 20 and FASB Statement No. 3” (“SFAS No. 154”). SFAS No. 154 requires retrospective application to prior periods’ financial statements for changes in accounting principle, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 also requires that retrospective application of a change in accounting principle be limited to the direct effects of the change. Indirect effects of a change in accounting principle should be recognized in the period of the accounting change. SFAS No. 154 also requires that a change in depreciation, amortization, or depletion method for long-lived non-financial assets be accounted for as a change in accounting estimate affected by a change in accounting principle. SFAS No. 154 is effective for accounting changes and

F-14

Notes to Consolidated Financial Statements—(Continued)

corrections of errors made in fiscal years beginning after December 15, 2005. The Company adopted the provisions of SFAS No. 154 as of October 1, 2006. The adoption of SFAS No. 154 did not have a material effect on the Company’s consolidated financial statements.

In June 2006, the FASB issued Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109, to clarify certain aspects of accounting for uncertain tax position, including issues related to the recognition and measurement of those tax positions. This interpretation is effective for fiscal years beginning after December 15, 2006, and therefore will apply to the Company beginning with its 2008 fiscal year beginning October 1, 2007. The Company is in the process of evaluating the impact of this interpretation on its consolidated financial statements.

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

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements When Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”), which provides interpretive guidance on how the effects of the carryover or reversal of prior year misstatements should be considered in quantifying a current year misstatement. The guidance is applicable for fiscal years ending after November 15, 2006. The Company adopted the provisions of SAB 108 as of September 30, 2007. The adoption of SAB 108 did not have a material effect on the Company’s consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an Amendment of FASB Statement No. 115” (“SFAS No. 159”). SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. Unrealized gains and losses on items for which the fair value option has been elected will be recognized in earnings at each subsequent reporting date. SFAS No. 159 is effective for the first fiscal year beginning after November 15, 2006. The Company is in the process of evaluating the impact, if any, of this interpretation on its consolidated financial statements.

2. Acquisitions:

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

Allowance for doubtful accounts		(549	)		(757	)
	$	18,510		$	20,720

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

At September 30, 2007 and September 30, 2006, the Company’s current notes receivable were $4.7 million and $1.4 million, respectively. The Company had a reserve for doubtful note of $0.5 million and zero, respectively, at September 30, 2007 and 2006. The Company also had notes receivable of $4.3 million and $2.3 million classified as long-term at September 30, 2007 and September 30, 2006, respectively. Notes receivable are generally collateralized by the products sold, and bear interest at rates ranging up to 12.0% per year. The notes receivable at September 30, 2007 will be due at various times through December 2010. The Company’s annual maturities of notes receivable will be approximately $5.2 million, $3.3 million and $0.9 million in the fiscal years ending September 30, 2008, 2009 and 2010 respectively.

Included in construction-in-progress is $10.8 million representing a newly constructed facility and related equipment for the expansion at the Company’s manufacturing facility in Houston, Texas. A significant portion of this construction-in-progress is expected to be commissioned by the Company in its first quarter of its fiscal year ending September 30, 2008. Included in construction-in-progress is $0.1 million of capitalized interest.

7. Intellectual Property; Film Supplier Developments:

In April 2002, the Company purchased for $2.3 million certain intellectual property rights from its then primary supplier of dry thermal film (the “Former Primary Film Supplier”). Such purchase gave the Company exclusive ownership of all technology used by the Former Primary Film Supplier to manufacture dry thermal film used in the thermal imaging equipment the Company manufactures. Such purchase included technology then existing and any dry thermal film technology thereafter developed by the Former Primary Film Supplier for use in the Company’s equipment. The Company also entered into an amended supply agreement pursuant to which the Former Primary Film Supplier agreed to provide the Company with dry thermal film. In connection with the purchase, the Company agreed to license the technology to the Former Primary Film Supplier on a perpetual basis so long as it could meet predefined quality and delivery requirements. If the Former Primary Film Supplier could not meet such requirements, the agreement provided the Company with the right to use the technology itself or to license the technology to any third party to manufacture dry thermal film.

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

F-17

OYO Geospace Corporation and Subsidiaries

Notes to Consolidated Financial Statements—(Continued)

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

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

On December 10, 2002, the Company received a notice of claim, in connection with the Former Primary Film Supplier’s bankruptcy, for alleged preferential payments made by the Former Primary Film Supplier to it in the period before filing of the bankruptcy proceeding in the approximate amount of $259,000. The Company recorded a provision for this claim based upon its estimate of the likelihood of a liability and probable loss. On July 7, 2004, an amended claim was filed against the Company and the amount of the alleged preferential payments made by the Former Primary Film Supplier was increased to approximately $895,000. On January 20, 2006, a motion to amend was filed regarding the claims pending against the Company. On August 28, 2006, the motion to amend was denied. The Former Primary Film Supplier’s bankruptcy proceeding has been converted to a Chapter 7 liquidation proceeding, and a trustee has been appointed for the bankrupt estate.

On March 8, 2007, the Company and the trustee for the bankruptcy estate entered into a court-approved settlement agreement pursuant to which the Company paid $95,000 to the bankruptcy estate in full settlement of the claims for preferential payments as described above. The Company’s general unsecured claim as a creditor of the Former Primary Film Supplier has been increased to include this $95,000 payment. The settlement agreement also provided for the full release of any claims by the bankruptcy estate against the Company. The Company is unable at this time to predict the outcome and effects of its claim as a creditor.

8. Notes Payable and Long-Term Debt:

Notes payable and long-term debt consisted of the following (in thousands):

	AS OF SEPTEMBER 30,

Notes to Consolidated Financial Statements—(Continued)

On November 22, 2004, several of the Company’s subsidiaries entered into a credit agreement (the “Credit Agreement”) with a bank. Under the Credit Agreement as amended on October 12, 2007 the Company’s borrower subsidiaries can borrow up to $25.0 million secured principally by their accounts receivable, inventories and equipment. The Credit Agreement expires on January 31, 2010. The Credit Agreement limits the incurrence of additional indebtedness, requires the maintenance of certain financial ratios, restricts the Company’s and the borrower subsidiaries’ ability to pay dividends and contains other covenants customary in agreements of this type. At September 30, 2007, there were borrowings of $0.9 million under the Credit Agreement, $0.5 million of standby letters of credit were outstanding and additional borrowings available of $23.6 million. The Company is not subject to a borrowing base and is able to borrow the full $23.6 million subject to it remaining in compliance with certain covenants. The Company was in compliance with all debt covenants as of September 30, 2007. The interest rate for borrowing under the Credit Agreement is, at the Company’s option, a discounted prime rate or a LIBOR based rate.

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

YEAR ENDING SEPTEMBER 30,
2008	$	322
2009		346

Medical claims		216		176
Other		1,310		797
	$	10,007	$	7,976

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

10. Employee Benefits:

The Company’s employees are participants in the OYO Geospace Corporation Employee’s 401(k) Retirement Plan (the “Plan”), which covers substantially all eligible employees in the United States. The Plan is a qualified salary reduction plan in which all eligible participants may elect to have a percentage of their compensation contributed to the Plan, subject to certain guidelines issued by the Internal Revenue Service. The Company’s share of discretionary matching contributions was approximately $0.5 million, $0.4 million and $0.3 million in fiscal years 2007, 2006 and 2005, respectively.

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

The Company’s employees are also participants in the OYO Geospace Corporation Fiscal Year 2006 Bonus Plan (the “Bonus Plan”). Every employee of the Company is eligible to participate in Tier I of the Bonus Plan except for 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 30% of consolidated pretax profits (before bonus) above a specified range. Selected employees are eligible to participate in Tier II of the Bonus Plan, which applies after Tier I is fully funded. The Tier II Bonus pool is established by accruing 30% of consolidated pretax profits (before bonus) within a 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 30% of consolidated pretax profits (before bonus) within a specified range above the Tier I and II ranges. The Company recorded bonus expense of $3.2 million, $3.0 million and $0.2 million for the fiscal years 2007, 2006 and 2005, respectively.

11. Stockholders’ Equity:

In September 1997, the board of directors and stockholders approved the 1997 Key Employee Stock Option Plan (the “Employee Plan”), and, following an amendment thereto, there has been reserved an aggregate of 1,125,000 shares of common stock for issuance thereunder. In November 1997, the board of directors and stockholders approved the Company’s 1997 Non-Employee Director Plan (the “Director Plan”) and following an amendment thereto, there has been reserved an aggregate of 150,000 shares of common stock for issuance thereunder. At September 30, 2007, the shares of common stock available for grant under the Employee Plan and Director Plan were 299,175 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 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

Notes to Consolidated Financial Statements—(Continued)

prior issuances by the Company of restricted stock were recorded at the fair value of the stock subject to those awards and were recorded as a component of stockholders’ equity, with a credit to additional paid-in capital. The Company recorded compensation expense based on the vesting criteria of the individual awards. The Company will account for future issuances of restricted stock awards in accordance with applicable guidelines, which require that stock-based awards be measured and recognized at fair value. All factors for the valuation of such awards will be determined under the Black-Scholes option-pricing model.

The Company established the Director Plan pursuant to which options to purchase shares of common stock are granted annually to non-employee directors and pursuant to which a portion of the annual fees paid for the services of such non-employee directors is payable in shares of common stock based on the fair market value thereof at the date of grant. 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 18,800 shares available for grant under this plan at September 30, 2007.

A summary of the activity with respect to stock options is as follows:

Deferred income taxes under the liability method reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s net deferred income tax asset were as follows (in thousands):

	AS OF SEPTEMBER 30,
	2007			2006
Deferred income tax assets:
Allowance for doubtful accounts	$	350		$	250
Inventories		1,545			1,161

Comprehensive income		(1,165	)		(562	)
Net deferred income tax asset	$	2,499		$	2,624

Deferred income taxes are reported as follows in the accompanying consolidated balance sheet (in thousands):

	AS OF SEPTEMBER 30,
	2007			2006
Current deferred income tax asset	$	2,391		$	1,805
Noncurrent deferred income tax asset		228			951
Current deferred income tax liability		(120	)		(132	)
	$	2,499		$	2,624

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

The financial reporting bases of investments in foreign subsidiaries exceed their tax bases. A deferred tax liability is not recorded for this temporary difference because the investment is essentially permanent. A reversal of the Company’s plans to permanently invest in these foreign operations would cause the excess to become taxable. At September 30, 2007 and 2006, the temporary difference related to undistributed earnings for which no

Notes to Consolidated Financial Statements—(Continued)

deferred taxes have been provided was approximately $14.4 million and $9.9 million, respectively. The Company will need to reassess and reassert its ability and intent to indefinitely reinvest the remaining foreign earnings in order to continue the application of the exception under APB 23.

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

As a result of the Company’s income for the year ended September 30, 2006, the Company was able to utilize foreign tax credits of $1.0 million, federal operating loss carryforwards of $0.5 million, alternative minimum tax carryforwards of $0.3 million, research and experimentation credits of $81,000 and general business credits of $46,000.

13. Earnings Per Common Share:

Basic earnings per share is computed by dividing net earnings available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is determined on the assumption that outstanding dilutive stock options have been exercised and the aggregate proceeds as defined were used to reacquire common stock using the average price of such common stock for the period.

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):

	YEAR ENDED SEPTEMBER 30,
	2007		2006		2005
Net income	$	19,599	$	9,770	$	2,507
Weighted average common shares and common share equivalents:
Common shares		5,793,840		5,686,600		5,606,858
Common share equivalents		269,606		269,312		136,743
Total weighted average common shares and common share equivalents		6,063,446		5,955,912		5,743,601
Earnings per share:
Basic	$	3.38	$	1.72	$	0.45
Diluted	$	3.23	$	1.64	$	0.44

Options totaling zero, 420 and 5,360 shares of common stock in fiscal years 2007, 2006 and 2005 respectively, were not included in the calculation of weighted average shares for diluted earnings per share because their effects were antidilutive.

14. Related Party Transactions:

Sales to OYO Japan and other affiliated companies were approximately $0.5 million, $0.6 million and $0.4 million during fiscal years 2007, 2006 and 2005, respectively. Purchases of inventory and equipment from OYO Japan were approximately $4,000, $0.1 million and $0.1 million during fiscal years 2007, 2006 and 2005, respectively.

15. Commitments and Contingencies:

Operating Leases

The Company leases certain equipment under short-term cancelable operating leases; therefore the Company does not have future minimum rental commitments under noncancelable operating leases. Rent expense was approximately $0.1 million for each of fiscal years 2007, 2006 and 2005, 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 September 28, 2007, Beijing JMT Science & Technology, Ltd., filed a lawsuit against Geospace Technologies, LP, OYOG, LLC, OYO Geospace Corporation, OYO Corporation U.S.A. and Geospace Engineering Resources International, LP in the State District Court of Harris County, Texas, alleging claims in quantum meruit, breach of contract, fraud and theft of service related to commission payments allegedly owed to the plaintiff. The plaintiff is seeking damages in the amount of $490,000 plus interest, fees, expenses and any other actual or punitive damages. The Company intends to defend vigorously against the plaintiff’s claims. The ultimate liability with respect to these claims cannot be determined at this time.

Other than the aforementioned lawsuit, the Company is not aware of any current or pending litigation or proceedings that could have a material adverse effect on the Company’s results of operations, cash flows or financial condition, although the Company continues to monitor developments in the bankruptcy proceeding by its Former Primary Film Supplier described in Note 7.

While the combination of the two segments resulted in more streamlined operations, the Company no longer segregates and reports certain balance sheet accounts for these segments. As a result, the Company has discontinued the reporting of business segment balance sheet information.

“Corporate” net sales consists of revenue from an operating lease of the Company’s Gessner building. “Corporate” loss from operations primarily consists of the Company’s Houston headquarter general and administrative expenses. Unallocated corporate assets primarily consist of the Company’s building, office equipment, deferred tax assets and other general assets.
