                     UNIT CORPORATION REPORTS FOURTH QUARTER
                         AND YEAR-END EARNINGS FOR 2003


     Tulsa, Oklahoma . . . Unit Corporation (NYSE - UNT) announced today its
financial and operational results for the fourth quarter and year-end 2003.
Year-over-year revenue improved 61%, a record for Unit. Year-over-year earnings
per share increased 145% to $1.15 per diluted share. The improvement in revenue
and net income was attributable to increases in drilling rig utilization and
dayrates, as well as increases in production of oil and natural gas and the
price received for those commodities. Drilling rig utilization averaged 62.9
rigs operating during 2003 versus 39.1 rigs operating during 2002. Unit added 13
drilling rigs during the year, bringing its fleet to a record 88 drilling rigs.
Unit replaced 166% of its oil and natural gas production, achieving its goal of
greater than 150% production replacement for the 20th consecutive year.
     For the fourth quarter of 2003, consolidated net income was $11.8 million,
or 27 cents per diluted share, on revenues of $83.0 million. In 2002, net income
for the fourth quarter was $6.8 million, or 16 cents per diluted share, on
revenues of $55.9 million.
     Net income for the year ended December 31, 2003 was $50.2 million, or $1.15
per diluted share, on revenue of $302.6 million. In 2002, net income was $18.2
million, or 47 cents per diluted share, on revenue of $187.6 million.
     Consolidated cash flow provided by operating activities for the fourth
quarter of 2003 was $33.3 million versus $16.3 million for 2002's corresponding
period. Cash flow provided by operating activities for the year was $121.7
million versus $70.5 million in 2002.





UNIT DRILLING RESULTS
     Contract drilling revenues increased 57% between the comparative fourth
quarters to $53.3 million, due to an increase in dayrates and drilling rig
utilization. Drilling rig rates for the fourth quarter averaged $8,128 per day,
10% higher than the comparable quarter of 2002. Contract drilling operating
margins per drilling rig averaged $1,815 per day in the fourth quarter of 2003
as compared to $1,440 for the same period in 2002. Higher insurance cost,
primarily from workers compensation reserves, negatively impacted operating
margins by $449 per day in the fourth quarter of 2003. The average drilling rig
utilization was 69.8 rigs in the fourth quarter of 2003, up 47% from 2002's
fourth quarter. With the acquisition of 12 drilling rigs during December of
2003, combined with an additional drilling rig that was built and placed into
service, Unit's fleet now totals 88 drilling rigs. Currently, 84 of the 88
drilling rigs are operating.
     Between the comparative years, contract drilling revenues increased 55% in
2003 to $183.1 million while drilling rig utilization increased to an average of
62.9 rigs operating during 2003, compared to 39.1 rigs operating during 2002.
Contract drilling operating margins increased to 24%, compared to 23% during
2002.

UNIT PETROLEUM RESULTS
     Fourth quarter production was 144,000 barrels of oil and 5,606 million
cubic feet (MMcf), a 21% equivalent Mcf increase from the fourth quarter of
2002. Revenues for the fourth quarter were $29.1 million or 39% higher than
2002's fourth quarter. The increase in revenue was due to higher oil and natural
gas prices and production.
     Unit's 2003 oil and natural gas production was 516,000 barrels of oil and
20,648 MMcf of natural gas, a 9% equivalent Mcf increase over 2002's production.
2003 oil and natural gas revenues were $116.6 million, a 72% improvement over
2002.
     Average natural gas prices received during the fourth quarter of 2003
increased 18% to $4.40 per thousand cubic feet (Mcf) compared to $3.74 per Mcf
during the fourth quarter of 2002. The average oil price received was $26.76 per
barrel in the fourth quarter of 2003 compared to $23.24 per barrel in the fourth
quarter of 2002, a 15% increase. For the year, the average natural gas price
received increased 70% to $4.87 per Mcf compared to $2.87 per Mcf during 2002.
The average oil price received was $26.94 per barrel during 2003 compared to
$21.54 per barrel in 2002, a 25% increase.
     During 2003, Unit drilled 149 wells, a 55% increase over the number of
wells drilled during 2002. Of the 149 wells, 128 wells, or 86%, were completed
as producing wells. Unit's total oil and natural gas reserves at December 31,
2003, were 285.0 billion cubic feet equivalent (Bcfe), a 6% increase over 2002.
Unit replaced 166% of 2003 production, achieving for the 20th consecutive year
the company's goal of replacing at least 150% of production with new oil and
natural gas reserves. Unit's three-year average finding cost was $1.65 per Mcfe.




MANAGEMENT COMMENTS
     "We are pleased with our fourth quarter 2003 and year-end results," said
John Nikkel, Chairman of the Board and Chief Executive Officer. "During December
of 2003, as a result of our acquisition of Serdrilco Incorporated, we acquired
12 additional drilling rigs, a fleet of 12 trucks and a district office and
equipment yard in and near Borger, Texas. This acquisition fits nicely with our
current drilling operations. Along with a rig that was recently built and placed
into service, Unit's drilling rig fleet now stands at 88 drilling rigs, the
largest in Unit's history."
     "Within our exploration and production operations, we completed our
acquisition of PetroCorp Inc., on January 30, 2004. Including PetroCorp's oil
and natural gas reserves, Unit's total oil and natural gas reserve base now
consists of 7.8 million barrels of oil and 294.5 Bcf of natural gas, a 27%
equivalent increase in total reserves over 2002. We plan to drill aggressively
during 2004, with a goal of drilling 165 to 175 wells. Our acquisition,
exploration and development drilling capital expenditure budget for 2004 is $95
million, an increase of 30% over 2003."

(1)  Unit Corporation considers Unit's cash flow from operations before changes
     in working capital an important measure in meeting the performance goals
     of the company.
(2)  Operating profit before depreciation is calculated by taking operating
     revenues by segment less operating expenses by segment excluding
     depreciation, depletion, amortization and impairment, general and
     administrative and interest expense. Operating margins are calculated
     by taking operating profit divided by segment revenues.
