FOR IMMEDIATE RELEASE


                 NATIONAL OILWELL AND VARCO ANNOUNCE SIGNING OF
                          DEFINITIVE MERGER AGREEMENT

HOUSTON, TX, August 12, 2004--National-Oilwell, Inc. (NYSE: NOI) and Varco
International Inc. (NYSE:VRC) jointly announced today the signing of a
definitive merger agreement.

The merger agreement, unanimously approved by each company's board of directors,
calls for Varco stockholders to receive 0.8363 shares of National Oilwell common
stock for each Varco common share, resulting in the combined company having
approximately 170 million shares outstanding on a fully diluted basis. Based on
National Oilwell's closing price yesterday, the transaction is valued at $25.80
per Varco common share, and the combined company would have a market
capitalization in excess of $5 billion. 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. Goldman, Sachs & Co. acted as
financial advisor to National Oilwell and Citigroup Global Markets Inc. acted as
financial advisor to Varco.
