DAWSON GEOPHYSICAL COMPANY 2001 ANNUAL REPORT ON FORM 10-K PART I. ITEM 1. BUSINESS GENERAL Founded in 1952, Dawson Geophysical Company acquires and processes seismic data used in the exploration, development and field management of oil and natural gas reserves. Since fiscal 1990, the Company has spent approximately $73 million to acquire new 3-D telemetry recording systems and associated equipment. The Company's operations consist of six 3-D seismic data acquisition crews and a seismic data processing center. As a result of continued industry-wide demand for the 3-D seismic method and the Company's competitive position, the Company has experienced increased market share for 3-D seismic services. During fiscal 2001, substantially all of the Company's revenues were derived from 3-D seismic operations. Since 1999, the Company has steadily increased its acquisition and processing of multi-component seismic data. The Company's land-based data acquisition crews operate primarily in the western United States. In 1997, the Company expanded its capabilities to accommodate more difficult and remote terrains such as east Texas and the Rocky Mountains with the addition of two crews equipped with the versatile I/O system Two RSR radio-based recording systems. Data processing is performed by Company geophysicists at the Company's computer center located in Midland, Texas. The Company acquires and processes data for its clients, ranging from major oil and gas companies to independent oil and gas operators, who retain exclusive rights to the information obtained. The Company believes that it maintains a competitive advantage in the industry by (i) acquiring equipment to expand capacity in response to client demand, (ii) updating its equipment base to take advantage of advances in geophysical technology, (iii) maintaining skilled and experienced personnel for its data acquisition and processing operations, (iv) focusing its operations on the domestic onshore seismic industry, and (v) providing integrated in-house operations necessary to complete all phases of 3-D seismic data acquisition and processing, including project design, permitting and surveying. GEOPHYSICAL SERVICES General. Technological advances in equipment and computers have allowed the seismic industry to economically acquire and process immense volumes of seismic data which produce more precise images of the earth's subsurface. The industry refers to this process of data acquisition, processing and subsequent interpretation of the processed data as the 3-D seismic method. Geophysicists use computer workstations to interpret 3-D data volumes, identify subsurface anomalies and generate a geologic model of subsurface features. 3-D seismic data are used in the exploration for new reserves and enable oil and gas companies to better delineate existing fields and to augment their reservoir management techniques. Benefits of incorporating 3-D seismic technology into exploration and development programs include reducing drilling risk, decreasing oil and gas finding costs and increasing the efficiencies of reservoir location, delineation and management. The Company is positioned to offer four-dimensional seismic surveys, which add the element of time to 3-D surveys. By surveying the same site at successive times, geophysicists compare data volumes and may be able to determine the progress of enhanced recovery programs in existing petroleum reservoirs, and thereby aid in extracting remaining reserves. Such projects could, over time, benefit reservoir management and provide future opportunities for the Company. The industry as a whole is investigating even more sophisticated technologies. The Company continues to explore the use of multi-component surveys utilizing shear wave information in the effort to identify and exploit recoverable oil and gas reserves. The Company's equipment currently includes vibrators and geophones capable of generating and recording shear waves. Data Acquisition. The seismic survey begins at the time a client requests the Company to formulate a proposal to acquire seismic data on its behalf. The Company's geophysicists then assist the client in designing the specifications of the proposed 3-D survey. If the client accepts the Company's proposal, a Company permit agent then obtains access from the landowner to the site where the survey is to be conducted. Utilizing electronic surveying equipment, the Company's survey personnel precisely locate the energy source and receiver positions from which the seismic data are collected. The Company utilizes the satellite global positioning system, known as GPS, to properly locate the seismic survey grid. 1

The Company owns equipment for six land-based crews gathering 3-D seismic data. The Company primarily uses vibrator energy sources, each of which weights 50,000 to 62,000 pounds, but on occasion detonates dynamite charges placed in drill holes below the earth's surface to generate seismic energy. The Company has 51 vibrator energy source units and a capacity of 21,000 recording channels, any of which are configured to meet the demands of specific survey designs. Each crew consists of approximately 50 technicians, 25 associated vehicles with off-road capabilities, 50,000 to 100,000 geophones, a seismic recording system, energy sources, electronic cables and a variety of other equipment. The Company operates six I/O System Two recording systems, two with RSR radio capability, and four MRX cable recording systems. Since 1994, the Company has grown from four seismic data acquisition crews with an aggregate recording capacity of 4,532 channels and 22 vibrator energy source units. Demand for more recording channels continues to increase from client companies as the industry strives for improved data quality. The Company's current average of 3,500 channels per crew is well above the industry average. The comparatively large number of recording channels gives the Company a competitive edge with the versatility and productivity to improve data quality at a lower cost per unit of data to the client. Data Processing. The Company currently operates a computer center located in Midland, Texas to process seismic data. Such processing primarily involves the enhancement of the data by improving reflected signal resolution, removing ambient noise and establishing proper spatial relationships of geological features. The data are then arranged in such a manner that computer graphic technology may be employed for examination and interpretation of the data by the user. The processing center operates 24 hours daily utilizing high-speed computers. The Company continues to improve data processing efficiency by further integrating workstation-based computer technology into the mainframe operation at the computer center and remote sites such as the client's office. The Company purchases, develops or leases, under non-exclusive licensing arrangements, seismic data processing software. The Company's computer center processes seismic data collected by its crews, as well as by other geophysical contractors. In addition, the Company reprocesses previously recorded seismic data using current technology to enhance the data quality. The Company's processing contracts may be awarded jointly with, or independently from, data acquisition services. Integrated Services. The Company maintains integrated in-house operations necessary to the development and completion of 3-D seismic surveys. Experienced Company personnel conduct and supervise the 3-D seismic survey design, permitting, surveying and data acquisition and processing functions for each seismic program. In-house support operations include facilities for automotive repair, automotive paint, electronics repair, electrical engineering and software development, thereby enabling better quality control and improved efficiency. The Company's clients generally undertake to provide their own interpretation of the seismic data provided by the Company, although from time to time the Company's geophysicists may assist its clients in this process. EQUIPMENT ACQUISITION The Company believes it is essential to monitor and evaluate advances in geophysical technology and to commit capital funds to purchase equipment it deems most promising. Purchasing new assets and continually upgrading capital assets involves a continuing commitment to capital spending. The Company remains committed to state of the art technology; however, capital expenses have been decreased during the 1999-2001 period of reduced operations. CLIENTS The Company's services are marketed by supervisory and executive personnel who contact clients to determine geophysical needs and respond to client inquiries regarding the availability of crews or processing schedules. These contacts are based principally upon professional relationships developed over a number of years. The Company's clients range from major oil companies to small independent oil and gas operators. The services provided by the Company vary according to the size and needs of the client. The Company presently believes that the loss of any one of its clients would not have a material impact on its business. CONTRACTS The Company's seismic services are conducted under master contracts with clients. Contracts are either "turnkey" contracts that provide for a fixed fee to be paid to the Company for each unit of data acquired, or "term" contracts that provide for a fixed hourly, daily or monthly fee during the term of the project. Turnkey contracts generally provide more profit potential for the Company, but involve more risks because of the potential downtime for weather and other types of delays. Substantially all of 2

the Company's contracts with its clients are turnkey. A supplemental agreement setting forth the terms of a specific project, which may be cancelled by either party, is entered into for every project. The results of the Company's services belong to the contracting party. To avoid conflicts of interest, the Company does not acquire any data for its own account. All of the client's information is maintained in strictest confidence. Company policy prohibits any officer, director or employee from participating in oil and gas ventures. COMPETITION AND MARKETS The acquisition and processing of 3-D seismic data for the oil and gas industry is a highly competitive business in the United States. Contracts for such services generally are awarded on the basis of price quotations, crew experience and availability of crews to perform in a timely manner, although factors other than price, such as technological expertise and reputation, are sometimes determinative. The Company's competitors include companies with financial resources that are significantly greater than those of the Company as well as companies of comparable and smaller size. Historically, the demand for geophysical services has been directly related to the level of spending by oil and gas companies for exploration, production, development and field management activities, which activities depend in part on the level of oil and gas prices. Because geophysical services are among the first operations involved in the exploration for oil and gas, the level of such services, in the past, has declined prior to a decline in oil and gas exploration activities. In recent years, however, the improved subsurface resolution obtainable from 3-D seismic data have enhanced the exploration for new reserves and enabled oil and gas companies to utilize 3-D surveys to better delineate existing fields and to augment their reservoir management techniques. See "Industry Conditions". EMPLOYEES The Company employs approximately 340 persons, of which 282 are engaged in providing energy sources and acquiring data, 12 are engaged in data processing, 7 are administrative personnel, 30 are engaged in equipment maintenance and 9 are executive officers. Of the employees listed above, 16 are geophysicists. The Company's employees are not represented by a labor union. The Company believes it has good relations with its employees. OPERATING HAZARDS AND INSURANCE The Company's activities are often conducted in remote areas under extreme weather and other dangerous conditions. These operations are subject to risks of injury to personnel and equipment. The Company's crews are mobile, and the equipment and personnel are subject to vehicular accidents. The Company uses diesel fuel which is classified by the U.S. Department of Transportation as a hazardous material. The Company carries insurance in amounts which it considers adequate on the principal items of its equipment. The Company does not carry insurance against certain risks, including business interruption resulting from equipment losses or weather delays. The Company obtains insurance against certain property and personal casualty risks when such insurance is available and when management considers it advisable to do so. Such coverage is not always available however, and when available, is subject to unilateral cancellation by the insuring companies on very short notice. The Company insures seismic data for amounts considered acceptable by management. Accordingly, damage to such data should not have a material adverse effect upon the Company. INDUSTRY CONDITIONS Demand for the Company's services depends upon the level of spending by oil and gas companies for exploration, production, development and field management activities, which activities depend in part on oil and gas prices. Beginning in 1998, a sharp decline in oil and gas prices led to a worldwide reduction in oil and gas activities. This decline resulted in a significant reduction in the overall demand for seismic services. Since reaching a recent high in 1998, the number of land-based seismic crews operating worldwide and the number of companies providing seismic services declined dramatically. Although demand for 3-D seismic data acquisition services has increased since a low of 2000, it has not yet returned to the levels experienced prior to 1998. Overcapacity in the industry continues to suppress pricing. Decreases in oil and gas activities have adversely affected the demand for the Company's services and the Company's results of operations. In addition, a decrease in oil and gas expenditures in the United States could result from such factors as unfavorable tax and other legislation or uncertainty concerning national energy policy. Any significant decline in oil and gas prices such as that which occurred in the late 1990's and 2001 could cause the Company to alter its capital spending plans. 3

WEATHER The Company's seismic data acquisition operations could be adversely affected by inclement weather conditions. Delays associated with weather conditions could negatively affect the Company's results of operations. PERMITS The Company's seismic data acquisition operations could be adversely affected by the inability of the Company to obtain right of way usage from land or mineral owners. Delays associated with permitting could negatively affect the Company's results of operations. OPERATING RISKS The Company's activities are subject to general risks inherent in land-based seismic data acquisition activities. To date, the Company has not suffered any material losses of equipment, but there can be no assurance that it will not experience such losses in the future. Because of the high fixed costs associated with the Company's 3-D equipment, any significant downtime or low productivity caused by reduced demand, weather interruptions, equipment failures, permit delays or other causes could adversely affect its results of operations. LIQUIDITY AND WORKING CAPITAL REQUIREMENTS The Company's sources of working capital are limited. The Company has funded its working capital requirements with cash generated from operations, cash reserves and borrowings from commercial banks. The Company's working capital requirements increased significantly during the last ten years, primarily due to the development of its 3-D land seismic data acquisition infrastructure. If the Company were to expand its operations at a rate exceeding operating cash flow, or if the current demand for pricing of geophysical services were to decrease substantially, additional financing could be required. There is no assurance that additional financing could or would occur. See "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources". RELIANCE ON KEY SUPPLIER The Company's primary supplier for seismic data acquisition systems is Input/Output, Inc. Although the Company believes it will be able to obtain data acquisition systems and/or replacement parts from Input/Output, Inc. or another source for such systems or parts in the future, should it be unable to do so, the Company's anticipated revenues could be reduced and the amount of cash needed for capital expenditures could be increased. See "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources - Capital Expenditures" and "Business - Equipment Acquisition". DEPENDENCE ON KEY PERSONNEL The Company's success may be dependent upon, among other things, the services of certain key personnel. The loss of services of any one or more of the executive officers of the Company could have a material adverse effect on or result in a disruption of normal business operations. COMPETITION The acquisition and processing of 3-D geophysical data for the oil and gas industry is a highly competitive business in the United States. The Company's competitors include companies with financial resources that are significantly greater than those of the Company as well as companies of comparable and smaller size. TECHNICAL OBSOLESCENCE Seismic data acquisition and data processing technology have progressed rapidly over the past several years, and the Company expects this progression to continue. The Company's strategy is to regularly upgrade its data acquisition and processing equipment to maintain its competitive position. However, due to the rapid advances in technology and the related costs associated with such technological advances, no assurance can be given that the Company will be able to fulfill its strategy, thus possibly affecting the Company's ability to compete. 4

GOVERNMENTAL REGULATIONS The Company's operations are subject to a variety of federal, state and local laws and regulations, including laws and regulations relating to the protection of the environment and archeological sites. The Company is required to expend financial and managerial resources to comply with such laws and related permit requirements in its operations, and anticipates that it will continue to be required to do so in the future. Although such expenditures historically have not been material to the Company, the fact that such laws or regulations change frequently make it impossible for the Company to predict the cost or impact of such laws and regulations on its future operations. The adoption of laws and regulations that have the effect of reducing or curtailing exploration and production activities by energy companies could also adversely affect the Company's operations by reducing the demand for its services. NO DIVIDENDS The Company has paid no cash dividends on its Common Stock since it has been a public company and has no plans to do so in the foreseeable future. The Company currently intends to retain earnings for use in its operations and to finance its business. DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS See Item 7.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read in conjunction with the Company's financial statements. In addition, in reviewing the Company's financial statements it should be noted that the Company's revenues directly relate to oil and gas exploration and production activity and fluctuations in the Company's results of operations may occur due to weather, land use permitting and other factors. FORWARD LOOKING STATEMENTS All statements other than statements of historical fact included in this report, including without limitation, statements under "Management's Discussion and Analysis of Financial Condition and Results of Operations" regarding the Company's financial position, business strategy and plans and objectives of management of the Company for future operations, are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. When used in this report, words such as "anticipate", "believe", "estimate", "expect", "intend", and similar expressions, as they relate to the Company or its management, identify forward-looking statements. Such forward-looking statements are based on the beliefs of the Company's management as well as assumptions made by and information currently available to the Company's management. Actual results could differ materially from those contemplated by the forward-looking statements as a result of certain factors, including but not limited to dependence upon energy industry spending, weather problems, inability to obtain land use permits, the volatility of oil and gas prices, and the availability of capital resources. Such statements reflect the current views of the Company with respect to future events and are subject to these and other risks, uncertainties and assumptions relating to the operations, results of operations, growth strategy and liquidity of the Company. All subsequent written and oral forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by this paragraph. The Company assumes no obligation to update any such forward-looking statements. OVERVIEW During fiscal 2001, the Company maintained an order book (cancelable) of three to four months for four to five data acquisition crews. As the Company was operating at this level at the end of fiscal 2000, it is apparent that current relatively low prices of oil and natural gas are sufficient to support continued exploration at current levels of activity. While excess capacity remains in the land-based seismic industry, moderate price recovery positively impacted the Company's revenues in fiscal 2001. FISCAL YEAR ENDED SEPTEMBER 30, 2001 VERSUS FISCAL YEAR ENDED SEPTEMBER 30, 2000 The Company's operating revenues increased 105% from $18,469,000 to $37,878,000 in fiscal year 2001. The Company began fiscal 2001 with five crews operating. During fiscal 2001, the Company experienced relatively level demand for its services as five data acquisition crews remained in operation. Revenues were also positively impacted in fiscal 2001 by moderate improvement in the pricing of its services. Inclement weather and permit delays had a negative impact on the fourth quarter revenues of fiscal 2001. Operating expenses in fiscal 2001 increased 52.2% as compared to fiscal 2000 as a result of increased demand for the Company's services. In January 2001, the Company restored salary reductions that had been enacted in January 1999. General and administrative expenses for fiscal 2001 totaled $1,819,000, a decrease of $307,000 from fiscal 2000. The decrease primarily consists of a decrease in the provision for doubtful accounts from the prior year. The Company has not made a provision for bad debts in fiscal 2001 as relatively favorable prices for crude oil and natural gas have correlated to collectibility of accounts receivable. Depreciation for fiscal 2001 totaled $8,802,000, a decrease of $615,000 from fiscal 2000. Depreciation decreased as a result of a suspension of capital expansion beginning in fiscal 1999 due to industry conditions. Total operating costs for fiscal 2001 totaled $43,654,000, an increase of 31.3% from fiscal 2000 due to the factors described above. The 105% increase in revenues as compared to the 31.3% increase of total operating costs for fiscal 2001 reflects the high proportion of relatively fixed total operating costs (including personnel costs of active crews and depreciation costs) inherent in the Company's business and continued price competition in the bidding process for geophysical services. No income tax expense was recorded for fiscal 2001 due to a pretax loss. The Company has no income tax benefit remaining due to the establishment of a valuation allowance offset by an increase in pretax loss. 8

FISCAL YEAR ENDED SEPTEMBER 30, 2000 VERSUS FISCAL YEAR ENDED SEPTEMBER 30, 1999 The Company's operating revenues decreased 23.7% from $24,198,000 to $18,469,000 in fiscal year 2000. The Company began fiscal 2000 with four crews operating. In March 2000, the crew count for the Company was reduced to two. Beginning in June, the number of crews gradually increased to five operating at September 30, 2000. Demand for the Company's services improved as requests for bids remained strong and revenues for the quarter ended September 30, 2000 increased significantly as compared to the same quarter of the prior year as well as the quarter ended June 30, 2000. Although production was approximately the same in fiscal 2000 as in the prior year, the decrease in revenues reflected continued severe price competition. Operating expenses in fiscal 2000 were basically unchanged as compared to fiscal 1999. Cost reduction measures, such as employee layoffs and salary reductions, were implemented in January 1999; however, the Company retained key field personnel in anticipation of increased demand. Accordingly, crews were placed back into service in the last quarter of fiscal 2000 as demand required. General and administrative expenses for fiscal 2000 totaled $2,126,000, a decrease of $264,000 from fiscal 1999. The decrease primarily consists of an adjustment made in the fourth quarter of fiscal 2000 of $253,000 to reduce the provision for doubtful accounts. Depreciation for fiscal 2000 totaled $9,417,000, a decrease of $1,168,000 from fiscal 1999. Depreciation decreased as a result of a suspension of capital expansion during fiscal 1999 due to industry conditions. Total operating costs for fiscal 2000 totaled $33,251,000, a decrease of 4.8% from fiscal 1999 due to the factors described above. The 23.7% decrease of revenues as compared to the 4.8% decrease of total operating costs for fiscal 2000 reflects the high proportion of relatively fixed total operating costs (including personnel costs of active crews and depreciation costs) inherent in the Company's business and fierce price competition in the bidding process for geophysical services. Income tax benefit for fiscal 2000 totaled $2,637,000, a decrease of $762,000 from fiscal 1999. The decrease in income tax benefit is due to the establishment of a valuation allowance in fiscal 2000 offset by an increase in pretax loss. The Company's effective tax benefit rate is different from the statutory rate of 34% primarily due to a valuation allowance of $1,848,000. LIQUIDITY AND CAPITAL RESOURCES Cash Flows Net cash provided by operating activities of $4,504,000 for fiscal 2001 primarily reflects the net loss offset by depreciation and of changes in working capital components. The decrease in income taxes receivable reflects the proceeds received as a result of the carryback generated by the net operating loss for fiscal 2000. Net cash used in investing activities reflects reduced capital expenditures and the maintenance of investments during the fiscal year. The cash flows provided by financing activities for fiscal 2000 represent the proceeds from the exercise of a stock option. Capital Expenditures The Company continually strives to supply market demand with technologically advanced 3-D data acquisition recording systems and leading edge data processing capabilities. Capital expenditures for fiscal 2000 consisted primarily of data acquisition channels that became available late in the year as a result of the idle capacity that exists in our industry. The Company maintains equipment in and out of service in anticipation of increased demand of the Company's services. In addition, the Company continues to monitor the development of the three component seismic approach. The Company feels that it is in position to respond to demand for this technological advancement of the seismic industry. Capital Resources The Company believes that its capital resources including its short-term investments, cash flow from operations and relationships with financial entities are adequate to meet its current operational needs and finance capital needs as determined by market demand and technological developments.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The primary sources of market risk include fluctuations in commodity prices which effect demand for and pricing of the Company's services and interest rate fluctuations. At September 30, 2001, the Company had no indebtedness. The Company's short-term investments are fixed rate and the Company does not necessarily intend to hold them to maturity, and therefore, the short-term investments expose the Company to the risk of earnings or cash flow loss due to changes in market interest rates. As of September 30, 2001, the carrying value of the investments approximate fair value. The Company has not entered into any hedge arrangements, commodity swap agreements, commodity futures, options or other derivative financial instruments. The Company does not currently conduct business internationally so it is generally not subject to foreign currency exchange rate risk. ITEM 8.

INDEPENDENT AUDITORS REPORT The Board of Directors and Stockholders Dawson Geophysical Company: We have audited the accompanying balance sheets of Dawson Geophysical Company as of September 30, 2001 and 2000, and the related statements of operations, stockholders' equity, and cash flows for each of the years in the three-year period ended September 30, 2001. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Dawson Geophysical Company as of September 30, 2001 and 2000, and the results of its operations and its cash flows for each of the years in the three-year period ended September 30, 2001, in conformity with accounting principles generally accepted in the United States of America.

DAWSON GEOPHYSICAL COMPANY NOTES TO FINANCIAL STATEMENTS 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization and Nature of Operations Dawson Geophysical Company (the "Company"), which was incorporated in Texas in 1952, has been listed and traded on the NASDAQ National Market System ("NMS") under the symbol "DWSN" since 1981. The Company acquires and processes 3-D seismic data for major and intermediate-sized oil and gas companies and independent oil operators who retain exclusive rights to the information obtained. The Company's land-based acquisition crews operate primarily in the western United States, and data processing is performed by geophysicists at the Company's computer center in Midland, Texas. Cash Equivalents For purposes of the statements of cash flows, the Company considers demand deposits, certificates of deposit and all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. Short-Term Investments The Company accounts for its short-term investments in accordance with Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities" (Statement 115). In accordance with Statement 115, the Company has classified its investment portfolio consisting of U.S. Treasury Securities as "available-for-sale" and records the net unrealized holding gains and losses as accumulated comprehensive income in stockholders' equity. The cost of short-term investments sold is based on the specific identification method. Fair Value of Financial Instruments The carrying amounts for cash and cash equivalents, short-term investments, accounts receivable, other current assets, accounts payable and other current liabilities approximate fair value due to the short maturity of these instruments. Concentrations of Credit Risk Financial instruments which potentially expose the Company to concentrations of credit risk, as defined by Statement of Financial Accounting Standards No. 105, consist primarily of trade accounts receivable and short-term investments. The Company's sales are to customers whose activities relate to oil and gas exploration and production. However, accounts receivable are well diversified among many customers, and a significant portion of the receivables are from major oil companies, which management believes minimizes potential credit risk. The Company generally extends unsecured credit to these customers; therefore, collection of receivables may be affected by the economy surrounding the oil and gas industry. The Company closely monitors extensions of credit and has initiated an allowance for doubtful accounts in fiscal 1999 as a result of the downturn in oil prices which occurred during the year and negatively impacted the Company's clients. The Company invests primarily in U.S. Treasury Securities and certificates of deposit which are low risk investments. Property, Plant and Equipment Property, plant and equipment are carried at cost. Depreciation is computed using the straight-line method. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is reflected in the results of operations for the period. Impairment of Long-Lived Assets The Company accounts for its long-lived assets in accordance with Statement of Financial Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" (Statement 121) which requires companies to assess their long-lived assets for impairment. Statement 121 requires companies to review for impairment whenever events or changes in circumstances indicate that the carrying amount of a long-lived asset may not be recoverable. No such provision was recorded in the Statement of Operations for the years ended September 30, 2001, 2000 and 1999. F-7

Reveue Recognition Contracts for service are provided for under cancelable contracts. The company recognizes revenue as services are performed. In the case of a cancelled contract, revenue is recognized and the customer is billed for services performed up to the date of cancellation. Income Taxes The Company accounts for state and federal income taxes in accordance with Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" (Statement 109). Under the asset and liability method of Statement 109, deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under Statement 109, the effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Use of Estimates in the Preparation of Financial Statements Preparation of the accompanying financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with Statement of Financial Accounting Standards No. 123, "Accounting For Stock-Based Compensation" (Statement 123). Statement 123 allows a company to adopt a fair value based method of accounting for a stock-based employee compensation plan or to continue to use the intrinsic value based method of accounting prescribed by Accounting Principles Board Opinion No. 25, "Accounting For Stock Issued To Employees" (APB No. 25). The Company has chosen to continue to account for stock-based compensation under APB No. 25 using the intrinsic value method. 2. SHORT-TERM INVESTMENTS Investment in securities, consisting entirely of U. S. Treasury Securities, having cost and market value of approximately the same amount. Short-term investments held at September 30, 2001 consisting of U.S. Treasury Securities and certificates of deposit have contractual maturities from December, 2001 through July, 2003. Securities that mature after September 30, 2002 are expected to be sold within one year and are properly classified as current assets. 3. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment, together with annual depreciation rates, consist of the following:

September 30 --------------------------------------------------- 2000 1999 Rates ------------ ------------ ----------------- Land, building and improvements $ 1,303,000 $ 1,303,000 3 to 12.5 percent Machinery and equipment 72,313,000 71,804,000 10 to 20 percent Equipment in process (a) 40,000 25,000 ------------ ------------ $ 73,656,000 $ 73,132,000 ============ ============
- ---------- (a) Equipment in process has not been placed into service and accordingly has not been subject to depreciation. F-8

4. STOCK OPTIONS The Company's 1991 Incentive Stock Option Plan, which extends the 1981 Plan, provides options to purchase 150,000 shares of authorized but unissued common stock of the Company. The option price is the market value of the Company's common stock at date of grant. Options are exercisable 25% annually from the date of the grant and the options expire five years from date of grant. The Company adopted the 2000 Incentive Stock Plan during fiscal 1999, which extends the 1991 Plan and provides options to purchase 500,000 shares of authorized but unissued common stock of the Company. In addition to the conditions described above regarding the 1991 Plan, the 2000 Plan provides that 50,000 of the 500,000 shares of authorized but unissued common stock may be awarded to officers, directors and employees of the Company for the purpose of additional compensation. The transactions under the Plans are summarized as follows:

Weighted Number of Average Price Optioned Shares ------------- --------------- Balance as of September 30, 1999 $ 9.32 208,000 Exercised $ 6.50 (5,000) Cancelled or expired $ 13.10 (22,000) -------- -------- Balance as of September 30, 2000 $ 8.93 181,000 Granted $ 8.65 70,000 -------- -------- Balance as of September 30, 2001 $ 8.86 251,000 ======== ========
Options for 103,000, 57,750 and 27,000 shares were exercisable with weighted average exercise prices of $10.78, $12.22 and $18.40 as of September 30, 2001, 2000 and 1999, respectively. Outstanding options at September 30, 2001 expire between September, 2002 and April, 2006 and have exercise prices ranging from $6.50 to $24.125. Options for 70,000 shares were granted in fiscal year 2001. The expected life of the options granted is five years. The weighted average fair value of options granted during 2001 is $4.07. The fair value of each option grant is estimated on the date of grant, using the Black-Scholes options-pricing model. The model assumed expected volatility of 61.27% and risk-free interest rate of 2.39% for grants in 2001. As the Company has not declared dividends since it became a public entity, no dividend yield was used. Actual value realized, if any, is dependent on the future performance of the Company's common stock and overall stock market conditions. There is no assurance the value realized by an optionee will be at or near the value estimated by the Black-Scholes model. No compensation expense has been recorded for the Company's stock options under the intrinsic value method. Had compensation cost for the 1991 Plan and the 2000 Plan been determined based on the fair value at the grant dates for awards made after September 30, 1995 under the 1991 Plan, the Company's net income and earnings per share would have been reduced to the pro forma amounts indicated below:
Year Ended Year Ended September 30, 2001 September 30, 2000 ------------------ ------------------ Net income As reported $ (4,978,000) $ (11,135,000) Pro forma $ (5,098,000) $ (11,255,000) ------------ ------------- Earnings per share As reported $ (.91) $ (2.05) Pro forma $ (.94) $ (2.07) ------------ -------------
Under the provisions of Statement No. 123, the pro forma disclosures above indicate only the effects of stock options granted by the Company subsequent to September 30, 1995. During this initial phase-in period, the pro forma disclosures as required by Statement No. 123 are not representative of the effects on reported net income for future years as options vest over several years. F-9

5. EMPLOYEE STOCK PURCHASE PLAN The Company has an employee stock purchase plan to invest in the Company's common stock for the benefit of eligible employees. Participants are entitled to contribute a percentage, not to exceed 5%, of their biweekly salary to the plan. On a biweekly basis, the Company matches the participants' contributions and directs the purchase of shares of the Company's common stock. There are no vesting requirements for the participants. The Company contributed $223,360, $240,328 and $214,347 to the plan during 2001, 2000 and 1999, respectively. 6. INCOME TAXES Income tax expense (benefit) attributable to income before extraordinary item consists of:

Year Ended September 30, ----------------------------------------------- 2001 2000 1999 --------- ------------ ------------ Current: U.S. federal $ -- $ (2,163,000) $ (1,441,000) State -- -- -- --------- ------------ ------------ -- (2,163,000) (1,441,000) Deferred: U.

Income tax expense varies from the amount computed by multiplying income before taxes by the statutory income tax rate. The reason for these differences and the related tax effects are as follows:

A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized. Based on expectations for the future, management has determined that taxable income of the Company will likely not be sufficient to fully utilize available carryforwards prior to their ultimate expiration. As such, the Company has recorded a valuation allowance of $3,507,000 to reflect the realizability of its net deferred tax assets. The amount of the valuation allowance could be reduced if estimates of future taxable income during the carryforward period are increased. As of September 30, 2001, the Company had a net operating loss carryforward for U.S. federal income tax purposes of approximately $13,796,000, which is available to offset future regular taxable income, if any. Net operating loss carryforwards in the amounts of $10,666,000 and $3,130,000 expire in 2019 and 2020 respectively. The Company has alternative minimum tax credit carryforwards totaling $813,000 to offset regular income tax, which have no scheduled expiration date. 7. NET LOSS PER COMMON SHARE The Company accounts for earnings per share in accordance with Statement of Financial Accounting Standards No. 128, "Earnings per Share" ("Statement 128"). Statement 128 replaced the calculation of primary and fully diluted earnings per share with basic and diluted earnings per share. Unlike primary earnings per share, basic earnings per share exclude any dilutive effects of options, warrants and convertible securities. Diluted earnings per share are very similar to the previously reported fully diluted earnings per share. All earnings per share amounts for all periods have been presented, and when appropriate, restated to conform to the Statement 128 requirements. The following table sets forth the computation of basic and diluted net income per common share:

Employee stock options to purchase shares of common stock were outstanding during fiscal year 2001 but were not included in the computation of diluted net loss per share because either (i) the employee stock options' exercise price was greater than the average market price of the common stock of the Company, or (ii) the Company had a net loss from continuing operations and, therefore, the effect would be antidilutive.

8. MAJOR CUSTOMERS The Company operates in only one business segment, contract seismic data acquisition and processing services. During 1999, sales to only one customer exceeded 10% of operating revenue. The percentage of sales to this customer in 1999 was 30.9%. During each of 2000 and 2001, sales to no customers exceeded 10% of operating revenue. 9. CONTINGENCIES The Company was a defendant in two lawsuits pending in the 112th and 83rd District Courts of Pecos County, Texas (respectively, Cause No. 8812, Ernestine Bernal, et al. vs. Javier Antonio Orona, et al.; and Cause No. P5565-83-CV, Carla Jaquez, et al. vs. Javier Antonio Orona, et al.) relating to a July 1995 accident involving a van owned by the Company which was used to transport employees to various job sites and a non-Company owned vehicle. Said litigation was settled within the limits of the Company's insurance coverage during fiscal 2001 without any cost or expense to the Company. The Company is party to other legal actions arising in the ordinary course of its business, none of which management believes will result in a material adverse effect on the Company's financial position or results of operation, as the Company believes it is adequately insured. On February 18, 1998 the Company entered into a five year, non-cancelable operating lease for office space. Future minimum lease commitments under the lease at September 30 of each year are $142,716 through 2002, declining to $107,037 in 2003. 10. RIGHTS AGREEMENT On July 13, 1999, the Board of Directors of the Company authorized and declared a dividend to the holders of record on July 23, 1999 of one Right (a "Right") for each outstanding share of the Company's common stock. When exercisable, each Right will entitle the holder to purchase one one-hundredth of a share of a Series A Junior Participating Preferred Stock, par value $1.00 per share, of the Company (the "Preferred Shares") at an exercise price of $50.00 per Right. The rights are not currently exercisable and will become exercisable only if a person or group acquires beneficial ownership of 20% or more of the Company's outstanding common stock or announces a tender offer or exchange offer, the consummating of which would result in attaining the triggering percentage. The Rights are subject to redemption by the Company for $.01 per Right at any time prior to the tenth day after the first public announcement of a triggering acquisition. If the Company is acquired in a merger or other business combination transaction after a person has acquired beneficial ownership of 20% or more of the Company's common stock, each Right will entitle its holder to purchase, at the Right's then current exercise price, a number of the acquired Company's shares of common stock having a market value of two times such price. In addition, if a person or group acquires beneficial ownership of 20% or more of the Company's common stock, each Right will entitle its holder (other than the acquiring person or group) to purchase, at the Right's then current exercise price, a number of the Company's shares of common stock having a market value of two times the exercise price. Subsequent to the acquisition by a person or group of beneficial ownership of 20% or more of the Company's common stock and prior to the acquisition of beneficial ownership of 50% or more of the Company's common stock, the Board of Directors of the Company may exchange the Rights (other than Rights owned by such acquiring person or group, which will have become null and void and nontransferable), in whole or in part, at an exchange ratio of one share of the Company's common stock (or one one-hundredth of a Preferred Share) per Right. The Rights dividend distribution was made on July 23, 1999, payable to shareholders of record at the close of business on that date. The Rights will expire on July 23, 2009. 11. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In June, 1998, the FASB issued SFAS No. 133 "Accounting for Derivative Instruments and Hedging Activities" which establishes standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. SFAS No. 133 requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. It establishes conditions under which a derivative may be designated as a hedge, and establishes standards for reporting changes in the fair value of a derivative. The Company adopted SFAS No. 133, as required by SFAS 137 "Deferral of the Effective Date of the FASB Statement No. 133," effective October 1, 2000. Based on the Company's preliminary assessment of the implications of this new statement, the Company believes it has no freestanding or embedded derivative instruments that would need to be accounted for under SFAS 133. F-12

In July 2001, the Financial Accounting Standards Board (FASB) issued Statements of Financial Accounting Standards No. 141 "Business Combinations" and No. 142 "Goodwill and Other Intangible Assets". Statement 141 requires that all business combinations initiated after June 30, 2001 be accounted for under the purchase method and Statement 142 requires that goodwill no longer be amortized to earnings, but instead be reviewed for impairment. As of September 30, 2001 the Company expects no impact to the financial statements, upon adoption, as no business combinations have been entered into, thus the potential for associated goodwill does not currently exist. Also, the FASB has voted to issue Statement No. 143 "Accounting for Asset Retirement Obligations" which establishes requirements for the accounting of removal-type costs associated with asset retirements. The standard is effective for fiscal years beginning after June 15, 2002, with earlier application encouraged. As of September 30, 2001 the Company expects no impact to the financial statements, upon adoption, as we do not believe that we incurred any obligations associated with asset retirements. On October 3, 2001, the FASB issued Statement No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets". This pronouncement supercedes FAS 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed" and eliminates the requirement of Statement 121 to allocate goodwill to long-lived assets to be tested for impairment. Statement 144 also describes a probability-weighted cash flow estimation approach to deal with situations in which alternative courses of action to recover the carrying amount of a long-lived asset are under consideration or a range is estimated for the amount of possible future cash flows. The statement also establishes a "primary-asset" approach to determine the cash flow estimation period for a group of assets and liabilities that represents the unit of accounting for a long-lived asset to be held and used. The provisions of this Statement are effective for financial statements issued for fiscal years beginning after December 15, 2001, and interim periods within those fiscal years. The Company is currently assessing the impact to its financial statements. 12. QUARTERLY FINANCIAL DATA (UNAUDITED)

LETTER TO SHAREHOLDERS FYE 9-30-01 Dear Shareholder: We are pleased to report significant progress for the Company's fiscal year ended September 30, 2001. Revenues of $37,878,000 exceeded those of the prior year by 105 percent. Cash generated by the Company in 2001, $3,824,000, compares quite favorably with the prior year cash loss of $1,718,000. This progress occurred against a background of fierce price competition due to low industry utilization rates. The Company's ability to employ its considerable experience in providing superior service along with high productivity accounted for our improved results. Results for the quarter ending September 30, 2001, while cash positive, were impacted by unexpected delays in securing right-of-way permits on otherwise workable projects. Cash generated in the quarter, $752,000, compares favorably with the cash loss of $256,000 a year ago. The enclosed financials reflect capital expenditures of $750,000 for the year; however, a total of approximately $1,000,000 was committed but such purchases were not delivered in the fiscal year. Purchases of both hardware and software enhancements along with replacements of rolling stock accounted for the majority of commitments. We contemplate a continuation of this level of capital expenditures for fiscal 2002, barring unforeseen expansions as this goes to press. We believe that we are in a sufficiently strong cash position, with no debt, to fund any such requirement. Following the practice of most publicly traded companies, we will discontinue mailing printed quarterly reports, opting instead to present these reports on our web site, www.dawson3d.com. For shareholders without internet access, we will be happy to provide reports upon request. Our current order book remains at the level of recent quarters, sufficient to keep four to five of our data acquisition crews busy. We are encouraged by this fact, occurring against a background of relatively low oil and gas prices. It can be deduced that any increases in oil and gas prices would increase levels of exploration expenditures. Meanwhile, we are continuing efforts to improve upon our productivity with a goal of profitability for fiscal 2002. Our efforts regarding the use of shear wave data as a viable development and exploration tool are ongoing. During the past year, we successfully completed several projects for multiple clients. While shear wave data acquisition remains a small portion of our order book, we are a leader in the domestic market in the implementation of this promising technology. Although small in today's world of public companies, your Company enjoys a significant share of the onshore U.S. geophysical market. We are in second place in acquisition crews operating and, off and on, tied for first in high channel count vibrator source 3-D, the leading edge technique of seismic exploration. Your support over the years has contributed invaluably to this success, for which we are extremely grateful. Sincerely, /s/ L. DECKER DAWSON /s/ STEPHEN C. JUMPER L. Decker Dawson Stephen C.
