Revenues                            $475,398        $500,576        $372,390
Net Income                          $ 20,360        $ 19,166        $ 16,961
Diluted Earnings Per Share          $   0.24        $   0.23        $   0.21


Consolidated revenues were down sequentially from the first quarter by $25
million, primarily due to lower capital equipment revenues. Consolidated
operating income as a percent of revenues was essentially flat in the second
quarter compared to the first.

Backlog of capital equipment at the end of the second quarter was $366 million,
also essentially flat on a sequential basis. Revenues from capital equipment for
the quarter totaled $155 million, and incoming orders declined to $153 million
from $174 million in the prior quarter. The China Joint Venture is not included
in backlog data.

Capital spending was $7.8 million, consistent with the first quarter of the year
and approximately 90% of the second quarter depreciation and amortization
charge.

PRODUCTS AND TECHNOLOGY GROUP

Product and Technology revenues declined due to the previously mentioned decline
in capital equipment revenues. Increased revenues in downhole tools and pump
expendables offset a portion of the decline. Operating income approximated 12%
of revenues.

DISTRIBUTION SERVICES GROUP

Distribution revenues increased by $5 million as strength in the United States
and outside North America offset the seasonal slowdown in Canada. Operating
income approximated 3% of revenues.

Pete Miller, President and CEO of National Oilwell, stated "We are very pleased
that net income in the second quarter improved sequentially and year over year.
Based on the marketplace trends that we are seeing, we believe that we will
achieve further improvement in net income during each of the next two quarters.

"Many of our businesses benefit disproportionately from drilling activity in the
Gulf of Mexico which remained flat in the second quarter. We continue to see
indications of improvement in this market that should translate into increased
future revenues from this area. While capital equipment orders in the quarter
were down sequentially, the likely sustainability of the order flow actually
improved as, unlike the first quarter, there were no new large projects added to
the backlog. We experienced broad demand for all types of equipment, with
continued emphasis from the offshore and international land markets."

The Company has scheduled a conference call today at 10:00 a.m. Central Time to
discuss second quarter results. The call will be broadcast through the Investor
Relations link on National Oilwell's web site at www.natoil.com, and a replay

time.
