Veritas Chairman and CEO, Thierry Pilenko, commented, “I am pleased to report that Veritas had a record fiscal year with revenue of $822 million and operating income of $133 million. Strong market conditions combined with impressive multi-client library performance led these excellent results that were across all operating regions and from all product lines. Although our fourth quarter is seasonally slow, revenue was up 31% to $178 million and operating income up $14 million to $12 million quarter-over-quarter. Our robust backlog as of July 31st of $456 million is indicative of the strength and longevity of increased exploration spending in the marketplace and extends our visibility well into 2007.

Looking to the future, I am very excited about the tremendous opportunity the definitive merger agreement between Compagnie Générale de Géophysique (CGG) and Veritas presents. The combination of these two excellent companies, together with the overall long-term market up cycle, will give us the ability to accelerate development of seismic technologies to better serve our customers worldwide and deliver superior returns to our investors.”

Multi-client

Multi-client revenue in the fourth quarter of fiscal 2006 increased $1 million or 2% from the prior year’s fourth fiscal quarter. The increase was primarily due to strong sales in land multi-client library in the US and Canada, partially offset by weaker sales in offshore West Africa.

Multi-client revenue for fiscal 2006 increased 44% from the prior fiscal year. Increased revenue was driven by strong marine library sales in the Gulf of Mexico and in Brazil. Multi-client land library sales were more than double from a year ago primarily due to sales in US and Canada.

Contract

Contract revenue in the fourth fiscal quarter of 2006 increased $40.6 million or 56% from the prior fiscal year with strong growth coming from marine acquisition and imaging work from across all geographic regions. The revenue increase was also due to land acquisition activities in Canada and in the Middle East.

Contract revenue in fiscal 2006 grew $81.1 million or 21% from the prior fiscal year. Increased revenue came from both land and marine work. Market conditions continue to improve and strengthen our business worldwide and we saw much of the growth in this fiscal year from land acquisition work in Canada and Alaska as well as increased imaging revenue across all geographic operating regions. Marine acquisition revenue remained strong in all geographic regions.

Operating Income

Operating income of $12.4 million in the fourth fiscal quarter of 2006 represents an increase of $14.2 million from the prior fiscal year’s fourth quarter loss of $1.8 million. The improvement in the operating income was driven by an increase in revenue in all regions combined with stronger multi-client operating margins. Operating income was also benefited by a $2.7 million reduction in depreciation expense. This reduction was because the land acquisition assets were considered held for sale for the last two months of the fiscal year and therefore no depreciation expense was recorded during this time. General and administrative expenses of $11.8 million increased $3.5 million from the prior year’s fourth fiscal quarter primarily due to non-recurring costs related to the

preparation of the potential sale of the land acquisition business, share-based employee compensation expense resulting from the adoption of new accounting rules, severance costs and increased provision for performance-based incentive compensation.

Operating income of $132.9 million in fiscal 2006 was $68.6 million higher than in fiscal year 2005. This performance was driven by increases in both multi-client revenue and multi-client operating margins. The overall operating margin was also driven by increased revenue and margins in land acquisition work due to increased activity in Canada and Alaska. Operating income was also benefited by the $2.7 million reduction in depreciation expense discussed above. General and administrative expenses of $43.2 million for the fiscal year 2006 increased $11.3 million from the prior fiscal year primarily due to non-recurring costs related to the preparation of the potential sale of the land acquisition business, share-based employee compensation expense resulting from the adoption of new accounting rules, severance costs and increased provision for performance-based incentive compensation.

Other Items

Interest expense increased by $1.0 million from the prior year’s fourth fiscal quarter as a result of increases in the interest rate on the $155.0 million convertible debt. Interest income increased approximately $2.2 million compared to the prior year’s fourth fiscal quarter due to higher interest rates and a higher cash balance.

The Company recognized a pre-tax insurance gain of $2 million in the first quarter of fiscal 2006 related to insurance settlements for the equipment loss on the Veritas Viking experienced in the second quarter of fiscal year 2005. In fiscal year 2005, the Company recognized a pre-tax gain of $10 million in the fourth quarter related to this insurance settlement.

Income Taxes

The Company’s effective tax rate for the quarter ended July 31, 2006 was 55.4% and for the fiscal year ended July 31, 2006 was 41.0%. These rates include approximately $2.5 million of additional tax cost associated with a $55 million one-time repatriation from one of our foreign subsidiaries pursuant to the American Jobs Creation Act of 2004. In the fourth quarter of fiscal 2005, the Company reversed $36.9 million of valuation allowances on certain of its deferred tax assets resulting in a net tax benefit of $37.3 million for the quarter and $6.8 million for the full fiscal year.

Backlog

At July 31, 2006, the Company’s backlog remains near record levels at $456 million compared to $460 million at the end of the third quarter and $302 million at the end of fiscal 2005.

Balance Sheet

The Company ended the fiscal year with approximately $402 million in cash and $155 million in convertible debt. Investment in the multi-client library, net of depreciation, was approximately $64.2 million for the fourth quarter compared to $70.8 million in the prior year’s fourth quarter. Our multi-client library balance was $296.6 million at July 31, 2006. As of July 31, 2006, the assets and liabilities related to our land acquisition business were considered held for sale.
