                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.       UNAUDITED INTERIM INFORMATION

         The unaudited interim financial  statements as of December 31, 2000 and
for each of the three month periods ended  December 31, 2000 and 1999,  included
herein, have been prepared by the Company, pursuant to the rules and regulations
of the  Securities  and Exchange  Commission  for interim  financial  reporting.
Accordingly,  these  financial  statements  and  related  information  have been
prepared  without audit, and certain  information and note disclosures  normally
included in financial  statements prepared in accordance with generally accepted
accounting  principles  have been  condensed  or  omitted,  although  management
believes  that the note  disclosures  are adequate to make the  information  not
misleading.  For interim  periods,  the Company  records  income taxes using the
expected effective tax rate for the fiscal year. In the opinion of the Company's
management,  the unaudited interim financial  statements reflect all adjustments
(consisting of normal  recurring  adjustments)  considered  necessary for a fair
presentation of the financial  position and results of operations of the Company
for the periods  presented.  The interim financial results may not be indicative
of  results  that  could be  expected  for a full year.  It is  suggested  these
condensed  consolidated  financial  statements be read in  conjunction  with the
consolidated  financial  statements  and  the  notes  thereto  included  in  the
Company's September 30, 2000 Annual Report to Shareholders.

4.  CHANGE IN DEPRECIATION POLICY

       In  November  2000,  the  Company  engaged an  independent  appraiser  to
evaluate  the  expected  useful lives of the ATWOOD  HUNTER,  ATWOOD  FALCON and
ATWOOD  EAGLE.  Based,  in part,  upon such  appraisal,  the Company,  effective
October 1, 2000,  extended  the  depreciable  lives of ATWOOD  HUNTER and ATWOOD
FALCON  from 12 to 22 years and will extend the  depreciable  life of the ATWOOD
EAGLE from 12 to 22 years  following the completion of its  water-depth  upgrade
planned at the end of fiscal 2001.  The Company  believes  that these changes in
depreciable  lives  provide a better  matching of the  revenues  and expenses of
these assets over their  anticipated  useful lives. This change in the Company's
depreciation policy lowered  depreciation  expense by $1.7 million for the three
months ended  December 31, 2000 and increased net income by $1.1 million  ($0.08
per diluted share).

5.  NEW ACCOUNTING PRONOUNCEMENTS

         Statement of Financial Accounting Standard ("SFAS") No. 133 establishes
accounting and reporting  standards  requiring  that any  derivative  instrument
(including  certain  derivative  instruments  embedded  in other  contracts)  be
recorded in the balance  sheet as either an asset or liability  measured at fair
value.  In the first quarter of fiscal 2001,  the Company  adopted SFAS No. 133,
which had no material impact on the Company's financial statements.

         In December  1999, the SEC staff issued Staff  Accounting  Bulletin No.
101 "Revenue  Recognition in Financial  Statements" which summarized the staff's
view on applying generally accepted accounting principles to revenue recognition
in financial  statements.  This bulletin has been amended to become effective no
later than the fourth quarter of fiscal years beginning after December 15, 1999,
which is the fourth  quarter of fiscal 2001 for the  Company.  In the opinion of
management, the Company's current accounting policies are in compliance with the
staff's  views,  and the adoption of SAB 101 will not have a material  impact on
the Company's financial statements.







                                 PART I. ITEM 2
                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS


     All non-historical  information set forth herein is based upon expectations
and  assumptions  deemed  reasonable  by the  Company.  The  Company can give no
assurance  that  such  expectations  and  assumptions  will  prove to have  been
correct,  and  actual  results  could  differ  materially  from the  information
presented herein.  The Company's  periodic reports filed with the Securities and
Exchange  Commission  should be  consulted  for a  description  of risk  factors
associated with an investment in the Company.

MARKET OUTLOOK

         The worldwide mobile offshore  drilling fleet  utilization is currently
in the 86% to 87% range. With anticipated increases in international exploration
and production  budgets  starting in 2001, the Company remains  optimistic about
improving  fundamentals  and the  long-term  offshore  drilling and  completions
markets. The Company anticipates that the ATWOOD HUNTER will enter a shipyard in
early  March 2001 to  commence  its $40 to 45 million  upgrade  and  enhancement
project.  With the ATWOOD HUNTER  anticipated  being off dayrate for five to six
months for its  upgrade,  the  Company's  quarterly  operating  results  for the
remainder of fiscal 2001 are expected to be lower than the results  realized for
the first quarter of fiscal 2001.  However,  even with the upgrade of the ATWOOD
HUNTER,  the  Company's  contract  backlog on its other  drilling  units  should
continue to provide a high level of revenues and cash flows in fiscal 2001.

RESULTS OF OPERATIONS

     Contract  revenues for the three months ended  December 31, 2000  increased
26% compared to the three months ended December 31, 1999. A comparative analysis
of contract revenues is as follows:

                                  ======               ======         ======

         The increase in revenues for the ATWOOD  SOUTHERN  CROSS was due to the
drilling  unit being  under  contract  during the first  quarter of fiscal  2001
compared to being idle during the  quarter  ended  December  31,  1999.  Revenue
increase  for the  SEAHAWK  was due to it  returning  to  work in  January  2000
following the completion of its upgrade,  whereby reduced revenues were received
during the upgrade  period.  The  increase in revenues  for the ATWOOD EAGLE and
RICHMOND  was due to higher  dayrates;  while the  decrease in revenues  for the
VICKSBURG and the ATWOOD HUNTER was due to reduction in dayrates. As a result of
drilling  operations  recommencing  on the NORTH RANKIN 'A'  platform  following
completion of its upgrade, revenues and costs increased on this operation.

         Contract  drilling  and  management  costs  increased  22% in the first
quarter of fiscal 2001 compared to the first quarter of fiscal 2000. An analysis
of contract drilling and management costs by rig is as follows:

         The increase in drilling costs for the ATWOOD SOUTHERN CROSS was due to
the  drilling  unit  being idle (at a reduced  level of costs)  during the first
quarter of fiscal 2000. The increase in the drilling costs for the ATWOOD HUNTER
was due to higher  maintenance  costs  being  incurred.  In December  1999,  the
SEAHAWK incurred  additional costs related to mobilization and preparing the rig
for  commencement  of  drilling  operations  following  its  upgrade;   thereby,
accounting for its decline in operating costs for the quarter ended December 31,
2000.

         An analysis  of  depreciation  expense by rig for the first  quarter of
fiscal 2001 compared to the first quarter of fiscal 2000 is as follows:

         The Company does not recognize depreciation expense during the period a
rig is out of service for a significant upgrade,  which accounts for the SEAHAWK
not having any  depreciation  for the first quarter of fiscal 2000. The decrease
in  depreciation  expense  for the ATWOOD  HUNTER  and ATWOOD  FALCON was due to
extending the depreciable  lives of these rigs (effective  October 1, 2000) from
12 to 22 years.

LIQUIDITY AND CAPITAL RESOURCES

         During the first  quarter of fiscal 2001,  operating  cash flow (before
changes in working capital and other assets and  liabilities)  was $15.0 million
compared to $11.9 million for the first quarter of fiscal 2000. During the first
quarter of fiscal 2001, the Company utilized  internally  generated funds, along
with  proceeds of $10 million from the treasury  note  maturity,  to invest $4.5
million  to  purchase  the  SEASCOUT  for  future  conversion  and  upgrade to a
semisubmersible  tender assist unit when an acceptable contract  opportunity has
been secured; to invest approximately $4.1 million in early order items relating
to the upgrade of the ATWOOD  HUNTER;  to invest  approximately  $2.6 million in
completing the upgrade of the RICHMOND;  and to fund  approximately $4.6 million
of other  capital  expenditures;  in addition to reducing  long-term  debt by $6
million.  The Company is finalizing  plans on the $40 to $45 million  upgrade of
the ATWOOD HUNTER, which is expected to commence in March 2001. Immediately upon
the ATWOOD EAGLE completing its current contractual  commitments (estimated late
fourth  quarter  fiscal  2001,  or  early  first  quarter  fiscal  2002)  it  is
anticipated  that the rig will enter a shipyard for an  approximate  $80 million
upgrade.

         The  Company  continues  to  explore  the market  for  possible  growth
opportunities.  Further  reduction or increase in long-term  debt will depend on
identifying  investment  opportunities  and timing of planned upgrade costs. The
Company's  current  $150 million  credit  facility  (with a current  outstanding
balance of $40  million)  should be more than  adequate  to provide  funding for
currently planned capital expenditures.  The Company will adjust planned capital
expenditures,  debt  repayment  and financing  requirements  in light of current
market conditions.
