FOR IMMEDIATE RELEASE


           NATIONAL OILWELL REPORTS FOURTH QUARTER AND 2002 EARNINGS


HOUSTON, TX, February 12, 2003--National-Oilwell, Inc. (NYSE: NOI) today
reported fourth quarter and full year 2002 revenues and net income. Net income
was $17.2 million, or $0.21 per diluted share, for the fourth quarter compared
to $17.8 million, or $0.22 per diluted share, in the third quarter. Revenues
were $393.6 million for the period compared to third quarter revenues of $366.9
million. Full year revenues and net income of $1,521.9 million and $73.1
million, $0.89 per diluted share, compare to 2001 results of $1,747.5 million
and $104.1 million, $1.27 per diluted share.

Backlog of capital equipment orders totaled $364 million at December 31, 2002,
including $170 million attributable to the acquisition of Hydralift. Excluding
any Hydralift effect, revenues from backlog for the fourth quarter were $91
million and for the full year 2002 were $390 million, with order additions to
the backlog for those same periods of $54 million and $199 million.

Pete Miller, President and CEO of National Oilwell, stated "Fourth quarter
financial results were generally in line with the prior quarter, as were
activity levels. Operating margins for our Products and Technology Group and our
Distribution Services Group were comparable with results achieved in the prior
two quarters. We are pleased with the overall results for the year, which
evidenced our ability to remain solidly profitable in a depressed drilling
market, and continued our long-term strategy of consolidating acquisitions that
enhance our performance throughout the cycle. Indicative of an improving market
outlook, we are beginning to experience increased activity in our Distribution
Services business, as well as in our non-capital equipment business.
Additionally, we continue to be very excited about the future financial impact
from the addition of our two recent acquisitions, Hydralift and Mono Pumps."
