NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(1) Basis of Presentation

     The consolidated balance sheet of Input/Output, Inc. and its subsidiaries (collectively referred to as the “Company” or “I/O”) at December 31, 2003 has been derived from the Company’s audited consolidated financial statements at that date. The consolidated balance sheet at June 30, 2004, the consolidated statements of operations for the three and six months ended June 30, 2004 and 2003, and the consolidated statements of cash flows for the six months ended June 30, 2004 and 2003, have been prepared by the Company without audit. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for the three and six months ended June 30, 2004 are not necessarily indicative of the operating results for a full year or of future operations.

     On June 14, 2004, the Company acquired all of the equity interests in GX Technology Corporation, a Texas corporation (GXT), through a combination of cash and stock option value totaling approximately $151.0 million, including acquisition costs. GXT, headquartered in Houston, Texas, is a leading provider of seismic imaging technology data processing and subsurface imaging services to oil and gas companies. The Company has included in its results of operations the results of GXT from the date of its acquisition.

     These consolidated financial statements have been prepared using accounting principles generally accepted in the United States for interim financial information and the instructions to Form 10-Q and applicable rules of Regulation S-X of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements presented in accordance with accounting principles generally accepted in the United States have been omitted. The accompanying consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2003 (as amended by Forms 10-K/A). Certain amounts previously reported in the consolidated financial statements have been reclassified to conform to the current period’s presentation.

(2) Summary of Significant Accounting Policies

     Refer to the Company’s Annual Report on Form 10-K (as amended by Forms 10-K/A) for the year ended December 31, 2003 for a complete discussion of the Company’s significant accounting policies. There have been no material changes in the current period regarding the significant accounting policies. As a result of the acquisition of GXT, the Company has adopted the following accounting policies related to the capitalization and amortization of multi-client data libraries and revenue recognition for imaging services and multi-client surveys.

     Multi-Client Data Library — The multi-client data library consists of seismic surveys that are offered for licensing to customers on a nonexclusive basis. The capitalized costs include costs paid to third parties for the acquisition of data and related activities associated with the data creation activity and direct internal processing costs, such as imaging, salaries, benefits, and other costs incurred for seismic data project design and management.

     Costs are amortized using the greater of (i) the percentage of actual revenue to the total estimated revenue multiplied by the estimated total cost of the project or (ii) a straight-line basis over the useful economic life of the data.

     The Company forecasts the ultimate revenue expected to be derived from a particular data survey over its estimated useful economic life to determine the costs to amortize, if greater than straight-line amortization. That forecast is made by the Company at the project’s initiation and is reviewed and updated periodically. If, during any such review and update, the Company determines that the ultimate revenue for a survey is expected to be less than the original estimate of total revenue for such survey, the Company increases the amortization rate attributable to future revenue from such survey. In addition, in connection with such reviews and updates, the Company evaluates the recoverability of the multi-client data library, and, if required under SFAS No. 144 “Accounting for the Impairment and Disposal of Long-Lived Assets,” records an impairment charge with respect to such data.

     Revenue Recognition — Revenues for imaging services are recognized on the percentage of completion method. During the acquisition and processing phase of a multi-client survey, the Company recognizes pre-funding revenue based on the percentage of completion, similar to the method for imaging services. After completion of a multi-client survey, the Company recognizes revenue upon delivery of data to the customer.

     The Company considers the percentage of completion method to be the best available measure of progress on these contracts. The percentage complete is assessed by measuring the actual progress to the estimated progress of the project. Accordingly, changes in job performance, job conditions, estimated profitability, contract price, cost estimates, and availability of human and computer resources are reviewed periodically as the work progresses and revisions to the percentage completion are reflected in the accounting period in which the facts require such adjustments become known. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. The asset “Unbilled Revenues” represents revenues recognized in excess of amounts billed. The liability “Deferred Revenue” represents amounts billed in excess of revenues recognized.

(3) Stock-Based Compensation

     The Company has elected to continue to follow the intrinsic value method of accounting for equity-based compensation as prescribed by APB Opinion No. 25. If the Company had adopted Statement of Accounting Standards (SFAS) No. 123, net income (loss), basic net income (loss) per share and diluted net income (loss) per share for the periods presented would have changed as follows (in thousands, except per share amounts):

     The above amounts are based on the Black-Scholes valuation model. The key variables used in valuing the options were as follows: average risk-free interest rate based on 5-year Treasury bonds, an estimated option term of five years, no dividends and expected stock price volatility of 60% during the three and six months ended June 30, 2004 and 2003.

(4) Segment and Geographic Information

     The Company evaluates and reviews results based on five segments (Land Imaging Systems, Marine Imaging Systems, Data Management Solutions, Seismic Imaging Solutions, and Corporate and Other) to allow for increased visibility and accountability of costs and more focused customer service and product development. The Company measures segment operating results based on income (loss) from operations.

     In June 2004, the Company acquired GXT and combined the operations of the Company’s existing Processing division with GXT to form the Seismic Imaging Solutions segment. Prior to December 31, 2003, the Company included the Processing division within the Land Imaging Systems segment due to its relatively low contribution margin to their operations. In February 2004, the Company acquired Concept Systems Holdings Limited (Concept Systems) and reports its results of operations and assets as the Data Management Solutions segment. See further discussion of the GXT and Concept acquisitions at Note 12 of Notes to Unaudited Consolidated Financial Statements. In addition, prior to June 30, 2004, the Company included its Applied MEMS division within the Land Imaging Systems segment due to its relatively insignificant results of operations. Beginning June 30, 2004, the Company has combined Applied MEMS within its Corporate and Other segment.

     A summary of segment information for the three and six months ended June 30, 2004 and 2003, reclassified for three and six months ended June 30, 2003 to reflect the Seismic Imaging Solutions segment and the combining of Applied MEMS within the Corporate and Other segment, is as follows (in thousands):

     Intersegment sales are insignificant for all periods presented. Corporate assets include all assets specifically related to corporate personnel and operations, a majority of cash and cash equivalents and all facilities that are jointly utilized by segments. Depreciation and amortization expense is allocated to segments based upon use of the underlying assets.

     A summary of net sales by geographic area is as follows (in thousands):

     Net sales are attributed to geographical locations on the basis of the ultimate destination of the equipment or service, if known, or the geographical area processing and imaging services are provided. If the ultimate destination of such equipment is not known, net sales are attributed to the geographical location of initial shipment.

(5) Accounts and Notes Receivable

     A summary of accounts receivable is as follows (in thousands):

     Approximately $4.5 million of the Company’s total accounts receivable at June 30, 2004 related to a July 2003 sale of an Image™ land data acquisition system to a customer located in China. This customer had experienced certain reliability issues with the system. The Company has resolved the reliability issues and is in the process of providing the customer with upgraded system components. All costs associated with the upgrade have previously been accrued as warranty expense. The Company expects to be paid in full once the customer’s Image systems have been upgraded. Therefore, no allowance has been established for this receivable.

     Notes receivable are collateralized by the products sold, bear interest at contractual rates of up to 12.7% per year and are due at various dates through 2006. The weighted average interest rate at June 30, 2004 was 7.7%. A summary of notes receivable, accrued interest and allowance for loan loss is as follows (in thousands):

     Approximately $10.4 million and $1.1 million of the Company’s total notes receivable and accounts receivable, respectively, at June 30, 2004 related to one customer, a subsidiary of Yukos, a major Russian energy company. Yukos is currently experiencing financial difficulties, which may result in its becoming subject to insolvency proceedings. During 2003, the customer became delinquent in making scheduled principal and interest payments under its notes to the Company in the amount of approximately $0.8 million, and it became delinquent in payment of approximately $1.8 million in trade payables it also owed to the Company. In January 2004, the Company refinanced these delinquent payment obligations into a new note totaling $2.6 million, with payments due in equal installments over a twelve-month period. During the second quarter of 2004, the customer then became delinquent in payment of all of its existing notes owed to the Company. The Company is currently renegotiating the terms of these notes with the customer and potential new investors in the customer, which may include extending the payment terms under the notes. Based on the discussions with the customer, its parent company, and the potential new investors, the Company expects the customer will pay all of its obligations in full and, therefore, no allowance has been established for these receivables.
