|1. | Significant Accounting Policies
|-- | -------------------------------

Basis
of Presentation

The consolidated balance sheet of OYO Geospace Corporation and its subsidiaries (the Company)
at September 30, 2010 was derived from the Companys audited consolidated financial statements at that date. The consolidated balance sheet at March 31, 2011 and the consolidated statements of operations for the three and six months
ended March 31, 2011 and 2010 and the consolidated statements of cash flows for the six months ended March 31, 2011 and 2010 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, 2011 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, 2010.

Reclassifications

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

Use of Estimates

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

Cash and Cash
Equivalents

The Company considers all highly liquid investments purchased with an original or remaining maturity at the
time of purchase of three months or less to be cash equivalents.

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. The Companys subsidiary in the Russian Federation uses an
average cost method to value its inventories.

Revenue Recognition

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

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



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



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



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



| |  |  | Collectibility is reasonably assured. The Company evaluates customer credit to ensure that collectibility of revenue is reasonably assured.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------

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



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



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



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



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



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



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



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



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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)



The Company does not modify its normal billing and credit terms for these types of
sales. As of March 31, 2011 and 2010, there were no sales 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):



|                                                                             |  |   |        |  
|---------------------------------------------------------------------------- |  | - | ------ | -
|Balance at the beginning of the period (October 1, 2010)                     |  | $ | 1,378  |  
|Accruals for warranties issued during the period                             |  |   | 1,838  |  
|Accruals related to pre-existing warranties (including changes in estimates) |  |   |       |  
|Settlements made (in cash or in kind) during the period                      |  |   | (1,089 | )
|                                                                             |  |   |        |  
|Balance at the end of the period (March 31, 2011)                            |  | $ | 2,127  |  
|                                                                             |  |   |        |  

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, therefore, cannot be determined with precision. The Company believes that the carrying amounts of its financial instruments, consisting of cash and cash equivalents, accounts and notes receivable and accounts payable, approximate the fair
values of such items as a result of the relative short term nature of such items.

Subsequent Events

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

Options totaling zero and 20,000 shares of common stock for the three and six months ended March 31,
2011 and 2010, respectively, were excluded from the computation of weighted average shares because the impact of considering these options was antidilutive.

|7. | Credit Agreement
|-- | ----------------

On
March 2, 2011, the Company entered into a new credit agreement (as amended, the New Credit Agreement) with a bank. Under the New Credit Agreement, the Company can borrow up to $25.0 million principally secured by its accounts
receivable, inventories and equipment. In addition, certain domestic subsidiaries of the Company have guaranteed the obligations of the Company under the New Credit Agreement and such subsidiaries have secured the obligations by the pledge of
certain of the assets of such subsidiaries. The New Credit Agreement expires on March 2, 2014. The New Credit Agreement limits the incurrence of additional indebtedness, requires the maintenance of certain financial ratios, restricts the
Company and its subsidiaries ability to pay dividends and contains other covenants customary in agreements of this type. The interest rate for borrowings under the New Credit Agreement is a LIBOR based rate with a margin spread of 250-350
basis points depending upon the maintenance of certain ratios. At March 31, 2011, the interest rate was 2.8%. At March 31, 2011, there were no borrowings outstanding under the New Credit Agreement and additional borrowings available were
$25.0 million.

Prior to entering into the New Credit Agreement, several of the Companys subsidiaries were a party to a
credit agreement (the Previous Credit Agreement) with a bank, and could borrow up to $25.0 million secured

principally by the subsidiaries accounts receivable and inventories. The Previous Credit Agreement, as amended, was scheduled to expire on April 11, 2011; however, this agreement was
terminated on March 2, 2011 and replaced by the New Credit Agreement. Borrowings under the Previous Credit Agreement were subject to borrowing base restrictions based on levels of eligible accounts receivable and inventories. The Previous
Credit Agreement limited the incurrence of additional indebtedness, required the maintenance of certain financial amounts, restricted the Companys and the borrower subsidiaries ability to pay dividends and contained other covenants
customary in agreements of this type.



|8. | Income Taxes
|-- | ------------

The United
States statutory tax rate applicable to the Company for the three months and six months ended March 31, 2011 and 2010 was 35% and 34%, respectively. The Companys effective tax rates for the three months ended March 31, 2011 and 2010
were 33.1% and 34.7%, respectively. The Companys effective tax rates for the six months ended March 31, 2011 and 2010 were 32.2% and 33.5%, respectively. Despite the lower statutory rate applicable to the Companys taxable income in
fiscal year 2010, the higher effective tax rate during each of the periods ended March 31, 2010 primarily resulted from the delay by the United States Congress of the extension of the research and experimentation tax credit to periods beyond
calendar year 2009. As a result of this delay, the Company was prohibited from recognizing approximately $150,000 of such tax credits during calendar year 2010. Recently, the United States Congress extended the research and experimentation tax
credit program through December 2012. During fiscal year 2011, the Company has recognized research and experimentation tax credits applicable to each quarterly period in fiscal year 2011, as well as the $150,000 of credits earned, but not
recognized, in fiscal year 2010.

From time to time the Company is the subject of audits by various tax authorities that can
result in claims and assessments and additional tax payments, penalties and interest. The United States Internal Revenue Service is in the process of conducting an audit of the Companys United States Federal income tax returns for fiscal years
2009, 2008 and 2007. Management believes that the outcome of such audit will not have a material effect on the Companys financial position, results of operations or cash flows.



|9. | Legal Proceedings
|-- | -----------------

On
July 8, 2009, the Company received a complaint filed in the United States District Court in Nevada alleging that the Geospace Seismic Recorder (GSR), the Companys newly developed wireless data acquisition system, infringes a
patent held by Ascend Geo, LLC (Ascend). The Company requested and was granted a change in venue to the United States District Court for the Southern District of Texas in Houston (the Court). In addition to monetary damages,
Ascend requested a preliminary injunction against future sales by the Company of the GSR nodal system. The Company filed its response with the Court requesting that it deny Ascends request for a preliminary injunction and, on November 4,
2009, the Court denied Ascends request for a preliminary injunction. On January 4, 2011, the Court dismissed Ascends case with prejudice. On April 5, 2011, the U.S. Patent and Trademark Office cancelled all claims of
Ascends patent. The Court denied the Companys request for reimbursement of legal expenses.



|10. | Early Extinguishment of Debt
|--- | ----------------------------

On December 15, 2010 the Company paid off a long-term mortgage note with a principal balance outstanding of $7.7 million. The Company was not required to pay any additional fees as a result of the
early extinguishment of the mortgage note.

statements. The occurrence of the events described in these risk factors and elsewhere in this Quarterly Report on Form 10-Q 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.

Industry Overview

OYO Geospace Corporation is a Delaware corporation incorporated on September 13, 1997. Unless otherwise specified, the discussion in
this Quarterly Report on Form 10-Q refers to OYO Geospace Corporation and its subsidiaries. We design and manufacture instruments and equipment used in the acquisition and processing of seismic data as well as in the characterization and monitoring
of producing oil and gas reservoirs. Demand for our products has been, and will likely continue to be, vulnerable to downturns in the economy and the oil and gas industry in general. During most of fiscal year 2010, oil and natural gas prices
remained at fairly consistent levels, but during fiscal years 2009 and 2008 there was substantial volatility in oil and natural gas prices. Please refer to the risks discussed under the heading Risk Factors in our Annual Report on Form
10-K for the fiscal year ended September 30, 2010 for more information.

We have been in the seismic instrument and
equipment business since 1980 and market our products primarily to the oil and gas industry. We also design, manufacture and distribute thermal imaging equipment and thermal media products targeted at the screen print, point of sale, signage and
textile market sectors. We have been manufacturing thermal imaging products since 1995. We report and evaluate financial information for each of these two segments: Seismic and Thermal Solutions.

Seismic Products

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

Seismic Exploration Products

A seismic energy source and a seismic data recording system are combined to acquire seismic data. We provide many of the components of
seismic data recording systems, including data acquisition systems, geophones, hydrophones, multi-component sensors, seismic leader wire, geophone strings, connectors, seismic telemetry cables and other seismic related products. On land, our
customers use our data acquisition systems, geophones, leader wire, cables and connectors to receive and measure seismic reflections resulting from an energy source to data recording

units, which store information for processing and analysis. In the marine environment, large ocean-going vessels tow long seismic cables known as streamers containing hydrophones
which are used to detect pressure changes. Hydrophones transmit electrical impulses back to the vessels data recording unit where the seismic data is stored for subsequent processing and analysis. Our marine seismic products help steer
streamers while being towed and help recover streamers if they become disconnected from the vessel.

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

During fiscal year 2008, we announced
the development of a land-based wireless (or nodal) data acquisition system. Each nodal station operates independently and therefore can be deployed in virtually unlimited channel configurations. Rather than utilizing interconnecting cables as
required by most traditional land data acquisition systems, each nodal station operates as an independent data collection system. As a result, our nodal system requires less maintenance, which we believe allows our customers to operate more
effectively and efficiently because of its reduced environmental impact, lower weight and ease of operation. Our nodal system is designed into configurations ranging from one to four channels per station. Since its introduction, we have sold and
delivered over 62,000 channels of our land-based nodal acquisition system. We also have over 24,000 additional channels available for rent to our customers and we intend to increase our rental fleet up to 30,000 total channels in fiscal year 2011
pending additional demand by our customers.

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

Our wholly-owned subsidiary in the Russian Federation manufactures international standard
geophones, sensors, seismic leader wire, seismic telemetry cables and related seismic products for customers in the Russian Federation and other international seismic marketplaces. Operating in foreign locations involves certain risks as discussed
under the heading Risk Factors  Our Foreign Subsidiaries and Foreign Marketing Efforts Face Additional Risks and Difficulties in our Annual Report on Form 10-K for the fiscal year ended September 30, 2010.

Seismic Reservoir Products

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

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

Emerging Technology Products

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

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

Thermal Solutions Products

Our thermal solutions product technologies were originally developed for seismic data processing applications. In 1995, we modified this technology for application in other markets. Our thermal printers
include both thermal imagesetters for graphics applications and thermal plotters for seismic applications. In addition, our thermal solutions products include direct-to-screen systems, thermal printheads, dry thermal film, thermal transfer ribbons
and other thermal media. Our thermal imaging solutions produce images ranging in size from 12 to 54 inches wide and in resolution from 400 to 1,200 dots per inch. We market our thermal imaging solutions to a variety of industries, including the
screen printing, point-of-sale, signage, flexographic and textile markets. We also continue to sell these products to our seismic customers.

The quality of thermal imaging is determined primarily by the interrelationship between a thermal printhead and the thermal media, be it film, ribbon, or any other media. We manufacture thermal printheads
and thermal film, which we believe will enable us to more effectively match the characteristics of our thermal printers to thermal film, thereby improving print quality, and make us more competitive in markets for these products.

We also distribute private label high-quality dry thermal media for use in our thermal printers and direct-to-screen systems. In
addition, we are continuously engaged in efforts to develop new lines of dry thermal film and ribbon in order to improve the image quality of our media for use with our printheads. In order to achieve more than marginal growth in our thermal
solutions product business in future periods, we believe that it is important to continue our concentration of efforts on both our printhead and media improvements.

Incentive Compensation Program

We adopted an incentive compensation
program for fiscal year 2011 whereby most employees will be eligible to begin earning incentive compensation if the Company reaches a five percent pretax return on stockholders equity, determined as of September 30, 2010. To be eligible
to participate in this incentive compensation program, employees must participate in our Core Values Program. Based on our experience in prior years, we expect one hundred percent of our eligible employees to participate in the Core Values Program.
The incentive compensation program does not apply to the employees of our Russian subsidiary as such employees participate in a locally administered bonus program. Certain non-executive employees are required to achieve specific goals to earn a
significant portion of their total incentive compensation award. Any bonus awards earned under this program in fiscal year 2011 will be paid out to eligible employees after the end of the fiscal year.

Upon reaching the five percent threshold under this proposed program, an incentive compensation accrual will be established equal to 14.5
percent of the amount of any consolidated pretax profits above the five percent pretax return threshold. The maximum aggregate bonus available under the program for fiscal year 2011 is $3.5 million. Under this program, for the six months ended
March 31, 2011 and 2010, we had accrued $3.5 million and $0.6 million, respectively, of incentive compensation expense.

Overview

Three and six months ended March 31, 2011 compared to three and six months ended March 31, 2010

Consolidated sales for the three months ended March 31, 2011 increased by $19.9 million, or 64.7%, from the corresponding period of
the prior fiscal year. Consolidated sales for the six months ended March 31, 2011 increased by $36.7 million, or 64.3%, from the corresponding period of the prior fiscal year. This increase reflects a substantial increase in sales and rentals
of our seismic products.

Consolidated gross profits for the three months ended March 31, 2011 increased by $11.4
million, or 110.7%, from the corresponding period of the prior fiscal year. Consolidated gross profits for the six months ended March 31, 2011 increased by $23.3 million, or 133.7%, from the corresponding period of the prior fiscal year. This
increase in consolidated gross profits resulted from (i) increased sales and rentals of seismic products, (ii) an improved product mix when compared to the six months ended March 31, 2010, and (iii) improved manufacturing
productivity due to higher production output.

Consolidated operating expenses for the three months ended March 31, 2011
increased by $2.8 million, or 47.2%, from the corresponding period of the prior fiscal year. Consolidated operating expenses for the six months ended March 31, 2011 increased by $4.7 million, or 41.3%, from the corresponding period of the prior
fiscal year. The increase in consolidated operating expenses resulted from (i) a general increase in expenses resulting from increased sales, (ii) improved pretax earnings giving rise to increased incentive compensation expenses of $0.8
million and $2.0 million during the three months and six months ended March 31, 2011, respectively, and (iii) increased product development expenditures of $0.5 million and $1.0 million for the three months and six months ended
March 31, 2011, respectively.

Other income (expense) for the three months ended March 31, 2011 decreased by $0.1
million from the corresponding period of the prior fiscal year. The change resulted primarily from foreign exchange losses incurred during the three months ended March 31, 2011. Other income (expense) for the six months ended March 31,
2011 increased by $0.2 million from the corresponding period of the prior fiscal year. The increase in other income

primarily resulted from (i) lower levels of interest expense resulting from lower levels of long-term debt, (ii) higher interest income from increasing levels of cash investments, and
(iii) a fee of $142,000 incurred during the three months ended December 31, 2009 from the early extinguishment of debt.

The United States statutory tax rate applicable to us for the three months and six months ended March 31, 2011 and 2010 was 35% and 34%, respectively. Our effective tax rates for the three months
ended March 31, 2011 and 2010 were 33.1% and 34.7%, respectively. Our effective tax rates for the six months ended March 31, 2011 and 2010 were 32.2% and 33.5%, respectively. Despite the lower statutory rate applicable to our taxable
income in fiscal year 2010, the higher effective tax rate during each of the periods ended March 31, 2010 primarily resulted from the delay by the United States Congress of the extension of the research and experimentation tax credit to periods
beyond calendar year 2009. As a result of this delay, we were prohibited from recognizing approximately $150,000 of such tax credits during calendar year 2010. Recently, the United States Congress extended the research and experimentation tax credit
program through December 2012. During fiscal year 2011, we have recognized research and experimentation tax credits applicable to each quarterly period in fiscal year 2011, as well as the $150,000 of credits earned, but not recognized, in fiscal
year 2010.

Seismic Products

Net Sales

Sales of our
seismic products for the three months ended March 31, 2011 increased by $19.7 million, or 72.0%, from the corresponding period of the prior fiscal year. Sales of our seismic products for the six months ended March 31, 2011 increased by
$36.4 million, or 72.4%, from the corresponding period of the prior fiscal year. The sales increase reflects (i) a strong product demand for our wireless data acquisition system, marine products, seismic reservoir products and equipment rentals
and (ii) improving seismic market conditions in Canada and the Russian Federation.

Operating Income

Our operating income associated with sales of our seismic products for the three months ended March 31, 2011 increased by $9.5
million, or 151.5%, from the corresponding period of the prior fiscal year. Our operating income associated with sales of our seismic products for the six months ended March 31, 2011 increased by $20.1 million, or 209.2%, from the corresponding
period of the prior fiscal year. The higher operating income resulted primarily from increased product sales and equipment rentals, improved factory productivity, and a more favorable product mix. The increase in operating income was partially
offset by increased incentive compensation expenses resulting from higher levels of pretax income and additional charges for inventory obsolescence expense due to the aging of certain inventories.

Thermal Solutions Products

Net Sales

Sales of our thermal solutions products for the three months ended March 31, 2011 increased by $0.2 million, or 6.2%,
from the corresponding period of the prior fiscal year. Sales of our thermal solutions products for the six months ended March 31, 2011 increased by $0.3 million, or 5.1%, from the corresponding period of the prior fiscal year. These increases
were primarily due to general increases in the sales of thermal imaging equipment, accessories and film. We consider these small increases to be normal due to recurring fluctuations in product sales volume and not associated with any long-term
trend.

Operating Income (Loss)

Our operating loss associated with sales of our thermal solutions products for the three months ended March 31, 2011 increased $17,000, or 35.4%, 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, 2011 decreased $0.3 million, or 73.4%, from the corresponding period of the prior fiscal year. The decline in profitability in
both periods resulted from increased incentive compensation expenses relative to the improvement in our consolidated financial results, and lower margins on product sales due to higher material costs.

Liquidity and Capital Resources

At March 31, 2011, we had $24.0 million in cash and cash equivalents. For the six months ended March 31, 2011, we generated
approximately $6.3 million of cash in operating activities. Sources of cash generated in our operating activities resulted from net income of $16.9 million. Additional sources of cash included net non-cash charges of $5.2 million for deferred income
tax benefit, depreciation, amortization, stock-based compensation, inventory obsolescence and bad debts. Other sources of cash included (i) a $10.6 million increase in accounts payable due to increased purchases of raw materials, (ii) a
$2.1 million increase in accrued expenses and other primarily resulting from the full accrual of compensation under the fiscal year 2011 incentive compensation plan, (iii) a $1.7 million increase in income tax payable resulting from income
taxes owed on our increased pretax profits, (iv) a $0.7 million decrease in other current assets resulting from a decrease in prepaid product purchases and (v) a $0.1 million increase in deferred revenue due to the collection of advanced
payments from our customers. These sources of cash were offset by (i) a $15.2 million increase in trade accounts and notes receivable primarily resulting from increased sales, and particularly higher levels of sales occurring near the end of
the second fiscal quarter, (ii) a $14.0 million increase in inventories due to the replenishment of low levels of GSR inventories, and increasing levels of work-in-process resulting from increased product orders and demand for rental equipment,
and (iii) a $1.7 million increase in the excess tax benefit from share-based compensation resulting from increased stock option exercises.

Throughout fiscal years 2009 and 2010, we made substantial efforts to reduce our inventory levels in order to meet declining levels of product demand for our traditional seismic products and to generate
cash flows to reduce our outstanding indebtedness. Due to significant demand for new products like our wireless data acquisition system, and our intention to increase our rental fleet of wireless equipment, we are strategically increasing certain
product inventories to meet this demand. However, we continue to be subject to high levels of inventory obsolescence expense for our older and slower moving traditional products. We are giving substantial attention to the management of our
inventories in this area.

For the six months ended March 31, 2011, we used approximately $11.5 million of cash in
investing activities for capital expenditures. In addition, we transferred $0.2 million of inventories to our rental equipment during fiscal year 2011 which had a non-cash impact. Due to high demand for our wireless rental equipment, we estimate
that our total capital expenditures in fiscal year 2011 could be approximately $20.0 million, including non-cash additions to our rental fleet. We expect these capital expenditures will be financed from our cash on hand, internal cash flow and/or
from borrowings under our New Credit Agreement.

For the six months ended March 31, 2011, we used approximately $4.6
million of cash in financing activities. These uses of cash included a $7.7 million principal payment for the early pay-off of a mortgage. These uses of cash were offset by a $1.7 million tax benefit related to the exercise of stock options and $1.4
million of cash proceeds received from the exercise of such stock options.

On March 2, 2011, we entered into a new
credit agreement (as amended, the New Credit Agreement) with a bank. Under the New Credit Agreement, we can borrow up to $25.0 million principally secured by our accounts receivable, inventories and equipment. In addition, certain of our
domestic subsidiaries have guaranteed our obligations under the New Credit Agreement and such subsidiaries have secured the obligations by the pledge of certain of the assets of such subsidiaries. The New Credit Agreement expires on March 2,
2014. The New Credit Agreement limits the incurrence of additional indebtedness, requires the maintenance of certain financial ratios, restricts us and our subsidiaries ability to pay dividends and contains other covenants customary in
agreements of this type. The interest rate for borrowings under the New Credit Agreement is a LIBOR based rate with a margin spread of 250-350 basis points depending upon the maintenance of certain ratios. At March 31, 2011, the interest rate
was 2.8%. At March 31, 2011, there were no borrowings outstanding under the New Credit Agreement and additional borrowings available were $25.0 million.

Prior to entering into the New Credit Agreement, several of our subsidiaries were a party to a credit agreement (the Previous Credit Agreement) with a bank, and could borrow up to $25.0
million secured principally by the subsidiaries accounts receivable and inventories. The Previous Credit Agreement, as amended, was

scheduled to expire on April 11, 2011, however this agreement was terminated on March 2, 2011 and replaced by the New Credit Agreement. Borrowings under the Previous Credit Agreement
were subject to borrowing base restrictions based on levels of eligible accounts receivable and inventories. The Previous Credit Agreement limited the incurrence of additional indebtedness, required the maintenance of certain financial amounts,
restricted the Companys and the borrower subsidiaries ability to pay dividends and contained other covenants customary in agreements of this type.

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

Critical Accounting Policies

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

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

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

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

We record a write-down of our inventories when
the cost basis of any manufactured product, including any estimated future costs to complete the manufacturing process, exceeds its net realizable value. Inventories are stated at the lower of cost (as determined by the first-in, first-out method)
or market value. Our subsidiary in the Russian Federation uses an average cost method to value its inventories.

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

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

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

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



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



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



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



| |  |  | Collectibility is reasonably assured. We evaluate customer credit to ensure collectibility is reasonably assured.
| | - |  | -----------------------------------------------------------------------------------------------------------------

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



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



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



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



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



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



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



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



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

We do not modify our normal billing and credit terms for these types of sales. As of March 31, 2011 and 2010, we had no sales under bill and hold arrangements.

|Item 3. | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------

We do not have any market risk as to market risk sensitive instruments entered into for trading purposes and have only very limited risk as to arrangements entered into other than for trading purposes.
Further, we do not engage in commodity or commodity derivative instrument purchasing or selling transactions. Because of the inherent unpredictability of foreign currency rates and interest rates, as well as other factors, actual results could
differ materially from those projected in this Item.

Foreign Currency and Operations Risk

One of our wholly-owned subsidiaries, OYO-GEO Impulse, is located in the Russian Federation. Therefore, our financial results may be
affected by factors such as changes in foreign currency exchange rates, weak economic conditions in the Russian Federation or changes in its political climate. Our consolidated balance sheet at March 31, 2011 reflected approximately $4.9
million of net working capital related to OYO-GEO Impulse. For third-party transactions, OYO-GEO Impulse both receives its income and pays its expenses primarily in rubles. To the extent that transactions of OYO-GEO Impulse are settled in rubles, a
devaluation of the ruble versus the U.S. dollar could reduce any contribution from OYO-GEO Impulse to our consolidated results of operations and total comprehensive income as reported in U.S. dollars. We do not hedge the market risk with respect to
our operations in the Russian Federation; therefore, such risk is a general and unpredictable risk of future disruptions in the valuation of rubles versus U.S. dollars to the extent such disruptions result in any reduced valuation of OYO-GEO
Impulses net working capital or future contributions to our consolidated results of operations. At March 31, 2011, the foreign exchange rate of the U.S. dollar to the ruble was 1:28.5. 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

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, 2011, we had outstanding accounts receivable of $2.8 million and $0.2 million from our subsidiaries in Canada and the Russian Federation, respectively. At March 31, 2011, the foreign
exchange rate of the U.S. dollar to the Canadian Dollar was 1:.97 and the foreign exchange rate of the U.S. dollar to ruble was 1:28.5. If the U.S. dollar exchange rate were to strengthen by ten percent against these foreign currencies, we would
recognize foreign exchange losses of $0.3 million in Canada and $18,000 in the Russian Federation.

Floating Interest Rate Risk

The New Credit Agreement contains a floating interest rate, which subjects us to the risk of increased interest costs
associated with any upward movements in bank market interest rates. Under the New Credit Agreement our borrowing interest rate is a LIBOR based rate plus 250-350 basis points. As of March 31, 2011, we had no borrowings under the New Credit
Agreement.

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

Our management is responsible for establishing and maintaining a system of disclosure controls and procedures that are designed to ensure
that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified under 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). 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 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, 2011 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 were effective as of March 31, 2011.

There were no changes in the Companys internal control over financial reporting that occurred during the Companys fiscal quarter ended March 31, 2011 that have materially affected, or are
reasonably likely to materially affect, the Companys internal control over financial reporting.
