NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1. Significant Accounting Policies

Basis of Presentation

The
consolidated balance sheet of OYO Geospace Corporation (OYO Geospace) and its subsidiaries (collectively, the Company) at September 30, 2007 was derived from the Companys audited consolidated financial statements
at that date. The consolidated balance sheet at March 31, 2008 and the consolidated statements of operations for the three and six months ended March 31, 2008 and 2007, and the consolidated statements of cash flows for the six months ended
March 31, 2008 and 2007 were prepared by the Company without audit. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary to present fairly the consolidated financial position, results of
operations and cash flows were made. The results of operations for the three and six months ended March 31, 2008 are not necessarily indicative of the operating results for a full year or of future operations.

Certain information and footnote disclosures normally included in financial statements presented in accordance with accounting principles generally
accepted in the United States of America were omitted. The accompanying consolidated financial statements should be read in conjunction with the financial statements and notes thereto contained in the Companys Annual Report on Form 10-K for
the year ended September 30, 2007.

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.

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 or market as determined by the
first-in, first-out method, except that inventories at the Companys subsidiary in the Russian Federation are stated on an average cost basis.

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, the Company does not recognize
the revenue attributable to the product as to which the performance test applies until the performance test is satisfied. Collection of this revenue may occur at various stages of production or after delivery of the product, and is not refundable to
the customer. Most of the Companys products do not require installation assistance or sophisticated instruction.

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



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



| |  |  | Delivery has occurred or services have been rendered. For product sales, the Company does not recognize revenues until delivery has occurred or performance tests
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 the Companys seismic customers are not able to take immediate delivery of products that 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, customers have asked the Company
to hold the equipment for a short period of time until they can take physical delivery of the product (referred to as bill and hold arrangements). The Company considers the following criteria for recognizing revenue when delivery has not
occurred:



| |  |  | Whether the risks of ownership have passed to the customer,
| | - |  | -----------------------------------------------------------



| |  |  | Whether the Company has obtained a fixed commitment to purchase the goods in written documentation from the customer,
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | Whether the customer requested that the transaction be on a bill and hold basis and the Company has received that request in writing,
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Whether there is a fixed schedule for delivery of the product,
| | - |  | --------------------------------------------------------------



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



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



| |  |  | Whether the equipment is complete and ready for shipment.
| | - |  | ---------------------------------------------------------

The Company does not modify its normal billing and credit terms for these types of sales. As of March 31, 2008, there were no sales recorded under bill and hold arrangements.

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 equipment 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 reflected in the following table (in thousands):



|                                                                             |  |   |        |

Recent Accounting Pronouncements

In June 2006, the FASB issued Interpretation No. 48 (FIN 48), Accounting for Uncertainty in Income Taxesan Interpretation of
FASB Statement No. 109, to clarify certain aspects of accounting for uncertain tax positions, including issues related to the recognition and measurement of those tax positions. The Company adopted the provisions of FIN 48 as of
October 1, 2007. The adoption of FIN 48 did not have a material effect on the Companys consolidated financial statements. The Company classifies interest and penalties associated with the payment of income taxes in the Other Income
(Expense) section of its consolidated statement of operations. Tax return filings, which are subject to review by local tax authorities by major jurisdiction, are as follows:



| |  |  | United States  fiscal years ended September 2004, 2005, 2006 and 2007
| | - |  | ----------------------------------------------------------------------



| |  |  | State of Texas  fiscal years ended September 2003, 2004, 2005, 2006 and 2007
| | - |  | -----------------------------------------------------------------------------



| |  |  | Russian Federation  calendar years 2005, 2006 and 2007
| | - |  | -------------------------------------------------------



| |  |  | Canada  fiscal years ended September 2004, 2005, 2006 and 2007
| | - |  | ---------------------------------------------------------------

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. The Company early adopted the provisions of SFAS 157 as of October 1, 2007. The
adoption of SFAS 157 did not have a material effect on the Companys consolidated financial statements.

In February 2007, the FASB
issued SFAS No. 159 (SFAS 159), The Fair Value Option for Financial Assets and Financial Liabilities  Including an Amendment of FASB Statement No. 115. SFAS 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. The Company early adopted the
provisions of SFAS 159 as of October 1, 2007. The adoption of SFAS 159 did not have a material effect on the Companys consolidated financial statements.

In December 2007, the FASB issued SFAS No. 141 (Revised 2007), Business Combinations (SFAS 141R).SFAS 141R will significantly change the accounting for business
combinations. Under SFAS 141R, an acquiring entity will be required to recognize all the assets acquired and liabilities assumed in a transaction at the acquisition date fair value with limited exceptions. SFAS 141R also includes a substantial
number of new disclosure requirements and applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. The Company does
not expect the adoption of SFAS 141R will have a material effect on its consolidated financial statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in
Consolidated Financial Statements  An Amendment of ARB No. 51 (SFAS 160). SFAS 160 establishes new accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a
subsidiary. This accounting standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. The Company will adopt SFAS 160 as of January 1, 2009. The Company does not expect
the adoption of SFAS 160 will have a material effect on its consolidated financial statements.

In March 2008, the FASB issued SFAS
No. 161 Disclosures about Derivative Instruments and Hedging Activities (SFAS 161). The new standard is intended to improve financial reporting of derivative instruments and hedging activities by requiring enhanced
disclosures to enable investors to better understand their effects on an entitys financial position, financial performance, and cash flows. It is effective for financial statements issued for fiscal years and interim periods beginning after
November 15, 2008, with early application encouraged. The new standard also improves transparency about the location and amounts of derivative instruments in an entitys financial statements; how derivative instruments and related hedged
items are accounted for under SFAS 133 Accounting for Derivative Instruments and Hedging Activities (SFAS 133); and how derivative instruments and related hedged items affect its financial position, financial performance, and
cash flows. The Company does not expect the adoption of SFAS 161 will have a material effect on its consolidated financial statements.

7. Credit Agreement

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, the Companys borrower
subsidiaries can borrow up to $25.0 million principally secured by their accounts receivable, inventories and equipment. The Credit Agreement expires on 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 March 31, 2008, there were
borrowings of $9.7 million under the Credit Agreement and additional borrowings available of $15.3 million. The Company is not subject to a borrowing base and is able to borrow the full $15.3 million subject to it remaining in compliance with
certain covenants. The Company was in compliance with all debt covenants as of March 31, 2008. The interest rate for borrowings under the Credit Agreement is, at our borrower subsidiaries option, a discounted prime rate or a LIBOR based
rate.

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

8. Income Taxes

The United States statutory tax rate for the periods ended March 31, 2008 and 2007 were 35.0% and 34.0%, respectively. The Companys effective tax rate for the three months ended March 31, 2008 and 2007
was 31.3% and 34.7%, respectively. The Companys effective tax rate for the six months ended March 31, 2008 and 2007 was 31.7% and 33.5%, respectively. When compared to the statutory rate, the lower effective tax rates from statutory rates
for each period reflect tax benefits related to (i) lower tax rates applicable to income earned in foreign jurisdictions, (ii) the manufacturers/producers deduction, and (iii) research and experimentation tax credits for
the periods ended March 31, 2008.

The Canadian Revenue Agency (CRA) is in the process of conducting a non-resident audit
of the Companys Canadian subsidiary. CRA has requested records and is in the process of examining such records. The Company does not believe the outcome of the CRA audit will have a material effect on its consolidated financial statements.

Industry Overview

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. We report and evaluate financial information for 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 data acquisition systems,
geophones, hydrophones, multi-component sensors, seismic leader wire, geophone strings, connectors, seismic telemetry cables and other seismic related products. On land, our customers use our 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 land wireless seismic data acquisition system
capable of very large channel configurations, which is now commercially available for sale. 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.

##### Table of Contents

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

Our wholly-owned subsidiary in the Russian Federation 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 in our Form 10-K for the fiscal year ended September 30, 2007.

Seismic Reservoir Products

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

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

In addition, we design and manufacture industrial sensors
for the vibration monitoring and earthquake detection markets. We also design and manufacture other specialty cable 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.

The quality of thermal images on film is determined primarily by the interface between a thermal printhead and the thermal film. We are 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.

##### Table of Contents

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.

Facilities Expansion

In fiscal year 2007, we completed a construction project to expand our Pinemont facility manufacturing space to approximately double its original size. We
are producing products in this facility and continue the process of adding and assembling the appropriate manufacturing machinery and equipment to expand our production capacity. The total cost of this facility expansion, including initial machinery
and equipment purchases, was $14.5 million. Costs for the facility expansion and machinery and equipment were funded from our internal cash flows and from borrowings under the Credit Agreement, discussed below under the heading Liquidity
and Capital Resources. In March 2008, we entered into a long-term loan secured by a mortgage on our Pinemont facility and used the proceeds to repay an existing $2.6 million mortgage on the Pinemont facility and the remaining proceeds were
used to repay borrowings under the Credit Agreement.

As a result of growth in our operations located in the Russian Federation, and with
an expectation of new product lines to be introduced over the coming years, we are evaluating plans to expand our manufacturing capacity there, 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 construction or acquisition of any additional space is estimated to cost up to $6.0 million. Any future expansion of our Russian facility is
expected to be financed from our internal cash flows and/or from borrowings under the Credit Agreement, discussed below under the heading Liquidity and Capital Resources.

Incentive Compensation Program

We adopted an
incentive compensation program for fiscal year 2008 whereby most employees will be eligible to begin earning incentive compensation upon the Company reaching a 5% pretax return on shareholders equity, determined as of September 30, 2007.
In addition, certain non-executive employees will be required to achieve specific goals to earn a significant portion of their total incentive compensation award. Bonus awards earned under this program will be paid out to eligible employees after
the end of fiscal year 2008.

Upon reaching the 5% threshold under this proposed program, an incentive compensation accrual will be
established equal to 20% of the amount of any consolidated pretax profits above the 5% pretax return threshold. The maximum aggregate bonus under the program for fiscal year 2008 is $3.6 million. Under the bonus program, for the three and six months
ended March 31, 2008 we have accrued $0.8 million and $1.7 million of incentive compensation expense, respectively.

Under a similar
program in fiscal year 2007, we accrued $3.2 million of incentive compensation expense for the three months ended December 31, 2006. This accrual represented 100% of the aggregate bonus allowed under the fiscal year 2007 incentive compensation
program. This large incentive compensation expense accrual resulted from the significant amount of pretax profits earned by the Company during the three months ended December 31, 2006, primarily resulting from the sale of a $16.2 million
reservoir characterization system to BP.

Overview

Three and six months ended March 31, 2008 compared to three and six months ended March 31, 2007

Consolidated
sales for the three months ended March 31, 2008 increased by $4.3 million, or 13.5%, from the corresponding period of the prior fiscal year. All product categories showed increases in revenues primarily driven by strong oil and gas exploration
and development activities and from new product introductions for the companys non-seismic businesses. Consolidated sales for the six months ended March 31, 2008 decreased by $8.4 million, or 10.9%, from the corresponding period of the
prior fiscal year. The decrease in sales primarily resulted from the revenue recognition in the prior fiscal year of $16.9 million from reservoir characterization systems, including a $16.2 million system sold to BP for installation in the Caspian
Sea. This decline in sales was partially offset by a $6.0 million increase in sales of borehole and other seismic reservoir products during the six months ended March 31, 2008. Sales of large scale systems like the $16.2 million system sold to
BP are infrequent and generally do not recur in each subsequent quarter. At this time, even if we receive a large order for a permanent reservoir characterization system similar in size to the $16.2 million system sold to BP in the prior year, it
would be unlikely that we could manufacture and deliver such a sizable system in this fiscal year. However, our active sales efforts continue for this important product line.

Consolidated gross profits for the three months ended March 31, 2008 decreased by $0.2 million, or 2.2%, from the corresponding period of the prior
fiscal year. Such decline in gross profits primarily resulted from approximately $1.2 million of losses resulting from production failures of two newly designed offshore cable products. In addition, during the three months ended March 31, 2008
incentive compensation expense related to our manufacturing employees increased $0.4 million since 100% of the fiscal 2007 incentive compensation expense was accrued in the first quarter of the prior fiscal year. Consolidated gross profits for the
six months ended March 31, 2008 decreased by $7.8 million, or 26.5%, from the corresponding period of the prior fiscal year. The decreased gross profits primarily resulted from the revenue recognition of the $16.2 million permanent reservoir
characterization system in fiscal year 2007, which, like all reservoir characterization systems, yielded a significantly higher gross profit margins than our other products. Partially offsetting these lower gross profit margins during the six months
ended March 31, 2008 was a decrease of $0.5 million in incentive compensation related to our manufacturing employees since 100% of the fiscal 2007 incentive compensation expense was accrued in the first quarter of the prior fiscal year.

Consolidated operating expenses for the three months ended March 31, 2008 increased $0.1 million, or
2.3%, from the corresponding period of the prior fiscal year. Components of the operating expense increase for the three months ended March 31, 2008 included (i) an increase of $0.3 million for new product research and development
activities, (ii) an increase of $0.5 million for incentive compensation expense for the reasons cited above, and (iii) increases in other general expenses resulting from higher sales levels. Offsetting these increases in operating expenses
is a decline of $0.6 million in bad debt expenses. Consolidated operating expenses for the six months ended March 31, 2008 decreased $0.5 million, or 3.9%, from the corresponding period of the prior fiscal year. Such decline primarily resulted
from a $1.0 million reduction of incentive compensation expense for our non-manufacturing employees for the reasons cited above. The reduction of incentive compensation was partially offset by an increase of $0.8 million for new product research and
development activities.

The estimated United States statutory tax rate for the periods ended March 31, 2008 and 2007 was 35.0% and
34.0%, respectively. Our effective tax rate for the three months ended March 31, 2008 and 2007 was 31.3% and 34.7%, respectively. Our effective tax rate for the six months ended March 31, 2008 and 2007 was 31.7% and 33.5%, respectively.
When compared to the statutory rate, the lower effective tax rates reflect tax benefits related to (i) lower tax rates applicable to income earned in foreign jurisdictions, (ii) the manufacturers/producers deduction, and
(iii) research and experimentation tax credits for the periods ended March 31, 2008.

The Canadian Revenue Agency
(CRA) is conducting a non-resident audit of our Canadian subsidiary. CRA has requested records and in the process of examining such records. We do not believe the outcome of the CRA audit will have a material effect on our consolidated
financial statements.

Seismic Products

Net Sales

Sales of our seismic products for the three months ended March 31, 2008 increased $3.6 million, or 12.6%, from the corresponding
period of the prior fiscal year. The increase in sales was primarily driven by a $1.8 million increase in sales of our borehole products and a $1.5 million increase in sales of our industrial products (including a $1.3 million increase in offshore
cable product sales). Sales of our seismic products for the six months ended March 31, 2008 decreased $9.1 million, or 13.0%, from the corresponding period of the prior fiscal year. The sales decrease was primarily due to our recognition in the
prior fiscal year of $16.9 million from reservoir characterization systems, including a $16.2 million system sold to BP for installation in the Caspian Sea. This decline in sales was partially offset by a $6.0 million increase in sales of borehole
and other seismic reservoir products during the six months ended March 31, 2008.

Operating Income

Our operating income for the three months ended March 31, 2008 decreased $0.8 million, or 11.7%, from the corresponding period of the prior fiscal
year. The decrease in operating income primarily resulted from approximately $1.2 million of losses resulting from production failures of two newly designed offshore cable products. Our operating income for the six months ended March 31, 2008
decreased $8.4 million, or 40.0%, from the corresponding period of the prior fiscal year. The decrease in operating income resulted from (i) the $1.2 million loss on the newly designed offshore cable products referred to above, and
(ii) the revenue recognition in the prior year of $16.9 million from reservoir characterization systems, including a $16.2 million system sold to BP for installation in the Caspian Sea.

Thermal Solutions Products

Net Sales

Sales of our thermal solutions products for the three months ended March 31, 2008 increased $0.6 million, or 18.0%, from the corresponding period of
the prior fiscal year. Sales of our thermal solutions products for the six months ended March 31, 2008 increased $0.5 million, or 6.9%, from the corresponding period of the prior fiscal year. These sales increases reflect improvements in both
film and equipment sales.

Operating Income

Our operating income associated with sales of our thermal solutions products for the three months ended March 31, 2008 increased $0.6 million, or 190.2%, from the corresponding period of the prior fiscal year.
Our operating income associated with sales of our thermal solutions products for the six months ended March 31, 2008 increased $0.6 million, or 360.9%, from the corresponding period of the prior fiscal year. The increase in operating income for
these periods resulted from increased sales of products with higher profit margins and, to a lesser extent, from manufacturing cost efficiencies.

Liquidity and Capital Resources

At March 31, 2008, we had $2.5 million in cash and cash equivalents. For the six
months ended March 31, 2008, we used approximately $11.4 million of cash from operating activities. The cash used in operating activities resulted from our net income of $6.5 million, which included non-cash charges of $2.3 million for
depreciation, amortization and stock-based compensation. Uses of cash from operating activities and changes in our working capital accounts included (i) an $11.7 million increase in accounts and notes receivable primarily resulting from
increased sales levels and from sales to customers requesting long-term financing assistance, (ii) a $5.7 million increase in inventories resulting from the development and production of new products (primarily the companys new GSR data
acquisition system) and a strong backlog of orders for our seismic exploration products, and (iii) a $1.6 million decrease in accrued and other expenses, resulting from the payment in the current fiscal year of fiscal year 2007 accrued
incentive compensation.

For the six months ended March 31, 2008, we used approximately $4.4 million of cash in investing activities.
Our capital expenditures of $5.1 million were partially offset by $0.7 million of cash received for the sale of a portion of a surplus property in the Russian Federation. We estimate that our total capital expenditures in fiscal year 2008 will be
approximately $10 million.

For the six months ended March 31, 2008, we generated approximately $15.6 million of cash in financing
activities primarily from net borrowings under the Credit Agreement, as discussed below.

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 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 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 March 31, 2008, there were borrowings of $9.7 million under the Credit Agreement and
additional available borrowings of $15.3 million.

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

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,



18



---

##### Table of Contents

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 do not
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.

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

Most of our products do not require installation assistance or
sophisticated instruction. We offer a standard product warranty 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,
| | - |  | -----------------------------------------------------------



19



---

##### Table of Contents

| |  |  | 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 March 31, 2008, we had no sales recorded under bill and hold arrangements.

Recent Accounting Pronouncements

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. We adopted the provisions of FIN 48 as of October 1, 2007. The adoption of FIN 48 did not have a material effect on our consolidated financial statements. We classify
interest and penalties associated with the payment of income taxes in the Other Income (Expense) section of our consolidated statement of operations. Tax return filings which are subject to review by local tax authorities by major jurisdiction are
as follows:



| |  |  | United States  fiscal years ended September 2004, 2005, 2006 and 2007
| | - |  | ----------------------------------------------------------------------



| |  |  | State of Texas  fiscal years ended September 2003, 2004, 2005, 2006 and 2007
| | - |  | -----------------------------------------------------------------------------



| |  |  | Russian Federation  calendar years 2005, 2006 and 2007
| | - |  | -------------------------------------------------------



| |  |  | Canada  fiscal years ended September 2004, 2005, 2006 and 2007
| | - |  | ---------------------------------------------------------------

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. We early adopted the provisions of SFAS 157 as of October 1, 2007. The adoption
of SFAS 157 did not have a material effect on our consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159
(SFAS 159), The Fair Value Option for Financial Assets and Financial Liabilities  Including an Amendment of FASB Statement No. 115. SFAS 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. We early adopted the provisions of SFAS 159 as of
October 1, 2007. The adoption of SFAS 159 did not have a material effect on our consolidated financial statements.

In December 2007,
the FASB issued SFAS No. 141 (Revised 2007), Business Combinations (SFAS 141R).SFAS 141R will significantly change the accounting for business combinations. Under SFAS 141R, an acquiring entity will be
required to recognize all the assets acquired and liabilities assumed in a transaction at the acquisition date fair value with limited exceptions. SFAS 141R also includes a substantial number of new disclosure requirements and applies prospectively
to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. We do not expect the adoption of SFAS 141R will have a material effect on our
consolidated financial statements.

In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in
Consolidated Financial Statements  An Amendment of ARB No. 51 (SFAS 160). SFAS 160 establishes new accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a
subsidiary. This accounting

standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. The Company will adopt
SFAS 160 as of January 1, 2009. We do not expect the adoption of SFAS 160 will have a material effect on our consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161 Disclosures about Derivative Instruments and Hedging Activities (SFAS 161). The new standard is intended to improve financial reporting of
derivative instruments and hedging activities by requiring enhanced disclosures to enable investors to better understand their effects on an entitys financial position, financial performance, and cash flows. It is effective for financial
statements issued for fiscal years and interim periods beginning after November 15, 2008, with early application encouraged. The new standard also improves transparency about the location and amounts of derivative instruments in an
entitys financial statements; how derivative instruments and related hedged items are accounted for under SFAS No. 133 Accounting for Derivative Instruments and Hedging Activities (SFAS 133); and how derivative
instruments and related hedged items affect its financial position, financial performance, and cash flows. We do not expect the adoption of SFAS 161 will have a material effect on our consolidated financial statements.

|Item 3. | 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 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 March 31, 2008 reflected approximately $5.7 million of net working capital related to this subsidiary. Our Russian subsidiary both receives its income and pays its expenses primarily in
rubles. To the extent that its transactions are settled in rubles, a devaluation of the ruble versus the U.S. dollar could reduce any contribution from this subsidiary 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 this subsidiarys net working capital or future contributions to our consolidated results of operations. At March 31, 2008, the foreign exchange rate of the U.S. dollar to the
ruble was 1:23.5. If the U.S. dollar versus ruble exchange rate were to decline by ten percent, our working capital would decline by $0.6 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 March 31, 2008, we had outstanding accounts and notes receivable of $0.8 million and $37,000 from our subsidiaries in the Russian
Federation and Canada, respectively. At March 31, 2008, the foreign exchange rate of the U.S. dollar to ruble was 1:23.5. If the U.S. dollar versus ruble exchange rate were to decline by ten percent our intercompany notes receivable could
decline by $83,000. 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 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, our borrowing rate is a LIBOR based rate plus 150 basis points. As of March 31, 2008, we had borrowings of $9.7 million under
the Credit Agreement at a borrowing rate of 3.9%. We also had borrowings of $8.8 million outstanding under our real estate mortgage agreement at a rate of 4.4%. Due to the amount of borrowings outstanding under these facilities, including potential
borrowings available under the Credit Agreement, increased interest costs associated with large movements in market interest rates could be material to our financial condition, results of operations and/or cash flow. At March 31, 2008, based on
our current level of borrowings, a 1.0% increase in interest rates would increase our interest expense annually by approximately $0.2 million in the aggregate.

|Item 4. | Controls and Procedures
|------- | -----------------------

Our management is
responsible for establishing and maintaining a system of disclosure controls and procedures that is 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 the Securities and Exchange Commission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). Nevertheless, 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 Quarterly Report on Form 10-Q, 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 March 31, 2008 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 Quarterly Report has been made known to them in a timely fashion.

During the quarter ended March 31, 2008, the Company installed new accounting software at its subsidiary in the Russian Federation. The new
accounting software contains automated internal control features that will permit the Company to migrate away from the manual internal control processes required by the older system. There were no other changes in the Companys internal
controls over financial reporting which occurred during the quarterly period ended March 31, 2008 that have materially affected, or are reasonably likely to materially affect, the Companys internal controls over financial reporting.
