NOTE D-INCOME TAXES

In February 2006, Olympic Seismic Ltd. ("Olympic"), a wholly owned subsidiary of the Company, was notified by Canada Revenue Agency ("CRA") that CRA was going to perform an audit of certain aspects of Olympic's tax returns for the years 2003 and 2004. In February 2009, CRA notified the Company that the current audit was expanded to include years from 2005 through 2007. In April 2011, the Company received notification that CRA concluded their audits, disallowing Olympic's deductions for certain royalties payable to the Company's U.S. entities for years 2003 to 2007. Olympic and the Company object to and are appealing the audit results. As a condition to appeal the audit results, Olympic was required to pay $7.6 million (Canadian) to CRA and did so in May 2011. As of June 30, 2011, the appeal process has not been concluded. The Company has recorded liabilities associated with potential adjustments that may occur as a result of the appeal based on management's assessment of the probability of the outcome of the appeal, net of certain payments made to CRA.
