All statements, other than statements of historical fact, are statements that could be deemed “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, including, without limitation, any projections of revenue, gross margin, expenses, earnings or losses from operations, or other financial items; future production volumes, results of exploration, exploitation, development, acquisition and operations expenditures, and prospective reserve levels of property or wells; any statements of the plans, strategies and objectives of management for future operations; any statement concerning developments, performance or industry rankings relating to services; any statements regarding future economic conditions or performance; any statements of expectation or belief; any statements regarding the proposed merger of Remington Oil and Gas Corporation into a wholly owned subsidiary of Helix or the anticipated results (financial or otherwise) thereof; and any statements of assumptions underlying any of the foregoing. The risks, uncertainties and assumptions referred to above include the performance of contracts by suppliers, customers and partners; employee management issues; complexities of global political and economic developments, geologic risks and other risks described from time to time in our reports filed with the Securities and Exchange Commission (“SEC”), including the Company’s Annual Report on Form 10-K for the year ending December 31, 2005; and, with respect to the proposed Remington merger, actual results could differ materially from Helix’s expectations depending on factors such as the combined company’s cost of capital, the ability of the combined company to identify and implement cost savings, synergies and efficiencies in the time frame needed to achieve these expectations, prior contractual commitments of the combined companies and their ability to terminate these commitments or amend, renegotiate or settle the same, the combined company’s actual capital needs, the absence of any material incident of property damage or other hazard that could affect the need to effect capital expenditures, any unforeseen merger or acquisition opportunities that could affect capital needs, the costs incurred in implementing synergies and the factors that generally affect both Helix’s and Remington’s respective businesses as further outlined in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in each of the companies’ respective Annual Reports on Form 10-K for the year ended December 31, 2005. Actual actions that the combined company may take may differ from time to time as the combined company may deem necessary or advisable in the best interest of the combined company and its shareholders to attempt to achieve the successful integration of the companies, the synergies needed to make the transaction a financial success and to

react to the economy and the combined company’s market for its exploration and production. We assume no obligation and do not intend to update these forward-looking statements.
