Stafford, Texas - November 21, 2002 - OYO Geospace Corporation (NASDAQ: OYOG) today reported sales of $65.0 million and net income of $1.1 million, or $0.20 per diluted share, for its fiscal year ended September 30, 2002. This compares with sales of $63.6 million and net income of $1.3 million, or $0.24 per diluted share, for the prior year. The company said that its fiscal 2002 results include (i) a $1.2 million impairment charge related to the bankruptcy of Labelon Corporation, the primary supplier of thermal film to the company's commercial graphics business segment, (ii) a $568,000 tax benefit resulting from the resolution of contingent tax matters and other adjustments relating to prior years, and (iii) a one-time extraordinary gain of $686,000, net of tax, associated with the company's increased ownership in OYO-GEO Impulse, our Russian subsidiary.

"Our full year revenue results reflect strong contributions from our new line of GeoRes reservoir characterization and monitoring systems and from our acquisition and consolidation of OYO-GEO Impulse. These revenue contributions combined to offset weak demand for traditional seismic equipment," said Gary D. Owens, OYO Geospace's Chairman.

For the fourth quarter, the company recorded sales of $13.6 million and a net loss of ($604,000), or ($0.11) per diluted share, as compared to sales of $15.9 million and a net loss of ($118,000), or $(0.02) per diluted share in the fourth quarter of the prior year. The company said that its fourth quarter 2002 results reflect ongoing weakness in seismic equipment market fundamentals and short-term interruptions in the company's commercial graphics operations due to disruptions in film supply associated with the Labelon bankruptcy. These events were only partially offset by a $1.2 million sale of the company's first GeoRes borehole system.

"Fiscal 2002 was indeed challenging as fundamentals in the traditional seismic equipment market continued to erode, reflecting both weak demand and manufacturing overcapacity. However, this was also the year in which our new GeoRes suite of reservoir characterization and monitoring systems became commercially available to the oil and gas industry. We are pleased with the strength of initial sales in this new market and the potential for additional sales in the coming year," said Owens.

"The flexible architecture of the GeoRes suite of systems enables each system to be ideally configured to meet client requirements. During fiscal 2002, we sold our first deepwater GeoRes system to a major oil company for permanent installation in the North Sea; our first retrievable deepwater reservoir characterization and monitoring system to a European contractor also for use in the North Sea; and our first retrievable borehole system for use by a contractor in the domestic frac-monitoring market," said Owens.

"As an outgrowth of our deepwater cable manufacturing operation, we recently introduced a new organization, Geo Space Offshore and Umbilical, capable of manufacturing cable products for the offshore construction and oil and gas industries. Sales from this new group are beginning to build and should play an increasingly important role in our operations in coming years," Owens said.

"Also, in November 2001 we increased our ownership interest from 44% to 85% in OYO-GEO Impulse, a Russian venture we entered into more than ten years ago. Since November 2001, we have transferred sensor-making technologies and manufacturing capabilities into this venture. In addition, OYO-GEO Impulse recently purchased a new facility that will be used to provide a high volume of low-cost sensors to the international marketplace. When the seismic market returns, we believe that OYO-GEO Impulse will provide strong growth for our conventional seismic products," Owens continued.

Commenting on the commercial graphics marketplace, Owens said, "In regards to our commercial graphics business segment, our sales of thermal film increased steadily throughout the year, serving to modestly offset declines in the sale of seismic equipment. However, the bankruptcy of Labelon in July 2002 caused short-term disruptions in both the quantity and quality of thermal film available for distribution to our customers. We have plans in place to make sure that film deliveries and quality issues will be back on track in the second quarter of fiscal 2003. Finally, our latest innovation, a new 1200 dpi printhead, was very well received at a recent nationwide trade show and should begin to ship in the second quarter. "

"Looking forward, it appears that fiscal 2003 will again be challenging with respect to our traditional seismic product lines as overall seismic activity remains at anemic levels," said Owens. "Near term, we also expect that our commercial graphics operations will continue to reflect film supply constraints until our film deliveries catch-up to demand. But we also have reason for optimism as we now see our backlog for GeoRes systems continuing to build, our new offshore and umbilical cable operations gaining momentum and the OYO-GEO Impulse venture continuing to increase its revenue contribution."

OYO Geospace designs and manufactures instruments and equipment used in the acquisition and processing of seismic data, in reservoir characterization and monitoring for the oil and gas industry and for the commercial graphics industry worldwide.

STAFFORD, Texas - August 1, 2002- OYO Geospace (NASDAQ: OYOG) today announced net income of $1.2 million, or $0.21 per diluted share, on revenues of $24.7 million for its third quarter ended June 30, 2002. This compares with net income of $628,000, or $0.11 per diluted share, on revenues of $15.8 million in the same quarter last year.

"Our third quarter results largely reflect a $15.8 million sale of a large GeoRes seabed reservoir characterization and monitoring system, one of our recently developed suite of geophysical data acquisition systems. An additional sale of $3.2 million to this customer, which is conditioned on the system's performance, may be recognized in the last calendar quarter of 2003," said Gary D. Owens, OYO Geospace's Chairman. "The $19 million, 10,000-channel system was the first of our new suite of reservoir characterization and monitoring systems to be delivered and will be trenched one meter below the ocean floor for life-of-field studies in the North Sea. We have subsequently sold another special-purpose system, a retrievable GeoRes, which will be used in the North Sea by another client to address specific reservoir characterization and monitoring challenges on another field."

"Market acceptance of the GeoRes suite of special-purpose systems is particularly gratifying as we have spent the past five years developing new technologies and flexible architectures to make the characterization and monitoring of deepwater reservoirs commercially practical," said Owens. "We believe that this is a new frontier for the seismic technique, in which seismic data will be used to substantially reduce costs associated with oil and gas exploration, production and development."

Commenting on the market for traditional land seismic products Owens said, "Overcapacity and pricing pressures in the seismic sector continue to constrain sales and margins as demand for traditional land seismic surveys remains weak in response to general economic conditions and structural changes within the energy industry. In response to this environment, we have taken a charge to cost of goods sold of $0.9 million for impaired inventory and other manufacturing fixed assets. While we expect that this environment will continue to suppress near-term results from our conventional seismic product lines, we believe that sales of our new GeoRes systems and services are gaining momentum and will play an increasingly important role in the company's future growth."

"Labelon Corporation, our alliance partner and a manufacturer of thermal film for our commercial graphics business segment, filed a Chapter 11 Reorganization petition in Federal Bankruptcy Court on July 3, 2002. We have recorded an impairment charge of $1.2 million in the current quarter against certain assets due to the uncertainty of their ultimate realization. Despite this situation, we believe prospects for our commercial graphics business segment continue to improve and that printer and film products under development will contribute significantly to this segment's future growth," Owens continued.

For the nine months ended June 30, 2002, OYO Geospace recorded sales of $51.4 million and net income of $1.7 million, or $0.31 per diluted share. This compares with sales of $47.7 million and net income of $1.5 million, or $0.26 per diluted share, for the comparable period last year.

The company also noted that its results for the quarter and year-to-date periods include a tax benefit of $422,000 and $489,000, respectively, reflecting the resolution of contingent tax matters and other adjustments relating to prior years.

OYO Geospace designs and manufactures instruments and equipment used in the acquisition and processing of seismic data for the oil and gas industry and for the commercial graphics industry worldwide.
