The fourth quarter guidance provided by the Company in its 2003 third quarter earnings release did not include the impact of the agreement announced today. Michael F. Curran, President and Chief Executive Officer commented, "We are very pleased to have reached this agreement and to deliver on our commitment to resolve a portion of the outstanding contract variances. We are continuing to work towards resolving our remaining claims under contracts with multiple international oil companies for variations, which currently total over $30 million. We expect to recover additional revenue related to these claims in future periods, although the timing and amount of potential future recoveries remain uncertain. Under our accounting policy, all expenses associated with contract variations are recorded as incurred, while revenue is only recorded when we reach an agreement with our customer. As a result, such future revenue will fall straight to the bottom line, except for taxes."
