On a fully-diluted basis, the current stockholders of National Oilwell will own approximately 51% of the combined company and the current stockholders of Varco will own approximately 49%. Upon the closing of the transaction, National Oilwell will change its corporate name to National Oilwell Varco, Inc. The transaction is expected to be tax free to Varco stockholders, and is expected to be accretive to earnings and cash flow per share for stockholders of both companies in 2005.

Pete Miller, Chairman, President and CEO of National Oilwell, will serve as President and Chief Executive Officer of the combined company. John Lauletta, Chairman and CEO of Varco, will serve as Chairman of the Board of the combined company, which will consist of equal representation from each company. Joe Winkler, President and Chief Operating Officer of Varco, will serve as the combined company's Chief Operating Officer.

"The combination of National Oilwell and Varco brings together some of the most respected product and service lines in the industry," stated Pete Miller. "It affords excellent opportunities for the stockholders, employees and customers of both companies, as National Oilwell Varco will be better positioned to compete effectively in the global market place. Customers will benefit from our ability to respond with an unparalleled level of quality in capital equipment, expendable products and services."

John Lauletta commented, "Both Varco and National Oilwell employees are known for their product innovation and dedication to customer service. We intend to fully leverage these shared values and common culture by focusing our combined efforts on research and development for the next generation of energy products as we anticipate the ever-growing worldwide demand for energy over the next few years."

Pete Miller added, "We expect approximately $40-50 million in annualized pre-tax cost savings and operating synergies to arise from overlapping production facility closures, IT infrastructure rationalization, sales and marketing expense reduction, and corporate overhead eliminations that should be achieved by the end of 2005."

The transaction is subject to various conditions including stockholder approval of both companies and customary regulatory approvals, including the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. It is anticipated that stockholders' meetings and the closing of the transaction would occur within four to six months. National Oilwell and Varco intend to file a joint proxy statement with the Securities and Exchange Commission shortly.
