Longstanding Customer Relationships International seismic contractors Indigenous seismic contractors State-owned oil and gas companies International service companies

Global Seismic Market Seismic industry is experiencing a dramatic decline in activity due to slow-down in exploration activity by oil and gas companies Excess capacity currently exists in the market, marine and land Most industry participants are reporting very weak financial results Some may not survive Pockets of activity and opportunities do exist Mitcham has seen relative strength in some international markets including natural gas exploration in Eastern Europe Advanced technology remains a priority for contractors due to increased efficiencies

Leading Manufacturer of Specialized Marine Equipment Seamap designs, manufactures and sells a variety of industry-leading products for marine market. Strong market position for energy source controllers with over 100 installations BuoyLink RGPS systems are now the primary choice for streamer and source tracking Streamer weight collars and other products “Sleeve Gun” energy source Replacement parts, engineering services, training, support and repair services Significant engineering and manufacturing capabilities Responsive business customer support

The Mitcham Leasing Model Unique business within seismic industry Leasing seismic equipment provides a cost effective alternative for seismic contractors Volume leverage in the business model at minimal incremental costs Equipment “agnostic” We support, not create, markets Customers dictate make-up of rental pool Advantages through supplier relationships Reliable, recurring purchaser of equipment Complement Original Equipment Manufacturers (OEMs)

Appendix- EBITDA Reconciliation

Adjusted EBITDA Reconciliation Non-GAAP Financial Measures: EBITDA is defined as net income before (a) interest income and interest expense, (b) provision for (or benefit from) income taxes and (c) depreciation and amortization. Adjusted EBITDA excludes non-cash foreign exchange gains and losses, non-cash costs of lease pool equipment sales, certain non-recurring contract settlement costs, impairment of intangible assets and stock-based compensation. This definition of Adjusted EBITDA is consistent with the definition in the Credit Facility. We consider EBITDA and Adjusted EBITDA to be important indicators for the performance of our business, but not measures of performance or liquidity calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We have included these non-GAAP financial measures because management utilizes this information for assessing our performance and liquidity, and as indicators of our ability to make capital expenditures, service debt and finance working capital requirements. The Credit Facility contains financial covenants based on EBITDA or Adjusted EBITDA. Management believes that EBITDA and Adjusted EBITDA are measurements that are commonly used by analysts and some investors in evaluating the performance and liquidity of companies such as us. In particular, we believe that it is useful to our analysts and investors to understand this relationship because it excludes transactions not related to our core cash operating activities. We believe that excluding these transactions allows investors to meaningfully trend and analyze the performance of our core cash operations. EBITDA and Adjusted EBITDA are not measures of financial performance or liquidity under GAAP and should not be considered in isolation or as alternatives to cash flow from operating activities or as alternatives to net income or as indicators of operating performance or any other measures of performance derived in accordance with GAAP. In evaluating our performance as measured by EBITDA, management recognizes and considers the limitations of this measurement. EBITDA and Adjusted EBITDA do not reflect our obligations for the payment of income taxes, interest expense or other obligations such as capital expenditures. Accordingly, EBITDA and Adjusted EBITDA are only two of the measurements that management utilizes. Other companies in our industry may calculate EBITDA or Adjusted EBITDA differently than we do, and EBITDA and Adjusted EBITDA may not be comparable with similarly titled measures reported by other companies.
