                          PART I. FINANCIAL INFORMATION
                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES


     This  Form 10-Q for the  quarterly  period  ended  June 30,  2005  includes
statements about Atwood Oceanics,  Inc. (which together with its subsidiaries is
identified  as the  "Company,"  "we"  or  "our,"  unless  the  context  requires
otherwise) which are not historical  facts (including any statements  concerning
plans  and   objectives  of  management   for  future   operations  or  economic
performance,   or  assumptions   related  thereto)  which  are   forward-looking
statements.  In addition,  we and our  representatives  may from to time to time
make other oral or written statements which are also forward-looking statements.

     These  forward-looking  statements are made based upon management's current
plans, expectations, estimates, assumptions and beliefs concerning future events
impacting  us and  therefore  involve a number of risks  and  uncertainties.  We
caution  that  forward-looking  statements  are not  guarantees  and that actual
results  could  differ  materially  from  those  expressed  or  implied  in  the
forward-looking statements.

     Important  factors that could cause our actual results of operations or our
actual financial  conditions to differ include,  but are not necessarily limited
to:

     - our dependence on the oil and gas industry;

     - the operational risks involved in drilling for oil and gas;

     - changes in rig utilization and dayrates in response to the level of
       activity in the oil and natural gas industry, which is significantly
       affected by indications and expectations regarding the level and
       volatility of oil and natural gas prices, which in turn are affected by
       such things as political, economic and weather conditions affecting or
       potentially affecting regional or worldwide demand for oil and natural
       gas, actions or anticipated actions by OPEC, inventory levels,
       deliverability constraints, and future market activity;

     - the extent to which customers and potential customers continue to pursue
       deepwater drilling;

     - exploration success or lack of exploration success by our customers and 
       potential customers;

     - the highly competitive and cyclical nature of our business, with periods
       of low demand and excess rig availability;

     - the impact of the war with Iraq or other military operations, terrorist 
       acts or embargoes elsewhere;

     - our ability to enter into and the terms of future drilling contracts;

     - the availability of qualified personnel;

     - our failure to retain the business of one or more significant customers;

     - the termination or renegotiation of contracts by customers;

                                       3



     - the availability of adequate insurance at a reasonable cost;

     - the occurrence of an uninsured loss;

     - the risks of international operations, including possible economic,
       political, social or monetary instability, and compliance with foreign
       laws;

     - the effect public health concerns could have on our international 
       operations and financial results;

     - compliance with or breach of environmental laws;

     - the incurrence of secured debt or additional unsecured indebtedness or 
       other obligations by us or our subsidiaries;

     - the adequacy of sources of liquidity;

     - currently unknown rig repair needs and/or additional opportunities to
       accelerate planned maintenance expenditures due to presently
       unanticipated rig downtime;

     - higher than anticipated accruals for performance-based compensation due
       to better than anticipated performance by us, higher than anticipated
       severance expenses due to unanticipated employee terminations, higher
       than anticipated legal and accounting fees due to unanticipated
       financing or other corporate transactions and other factors that could
       increase general and administrative expenses;

     - the actions of our competitors in the oil and gas drilling industry, 
       which could significantly influence rig dayrates and utilization;

     - changes in the geographic areas in which our customers plan to operate,
       which in turn could change our expected effective tax rate;

     - changes in oil and natural gas drilling technology or in our competitors'
       drilling rig fleets that could make our drilling rigs less competitive or
       require major capital investments to keep them competitive;

     - rig availability;

     - the effects and uncertainties of legal and administrative proceedings 
       and other contingencies;

     - the impact of governmental laws and regulations and the uncertainties 
       involved in their administration, particularly in some foreign 
       jurisdictions;

     - changes in accepted interpretations of accounting guidelines and other 
       accounting pronouncements and tax laws; and

     - the risks involved in the construction and upgrade of our drilling units.

                                       4




Undue reliance should not be placed on these forward-looking statements, which
are applicable only on the date hereof. Neither we nor our representatives have
a general obligation to revise or update these forward-looking statements to
reflect events or circumstances that arise after the date hereof or to reflect
the occurrence of unanticipated events.

                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.   UNAUDITED INTERIM INFORMATION
 
     The unaudited interim  condensed  consolidated  financial  statements as of
June 30,  2005 and for each of the three and nine month  periods  ended June 30,
2005 and 2004, included herein, have been prepared in accordance with accounting
principles  generally  accepted  in the  United  States of America  for  interim
financial  information and with the instructions for Form 10-Q and Article 10 of
Regulation  S-X.  The year end  condensed  consolidated  balance  sheet data was
derived from the audited financial statements as of September 30, 2004. Although
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 accounting principles generally
accepted in the United  States of America  have been  condensed  or omitted,  we
believe  that the note  disclosures  are  adequate to make the  information  not
misleading.  The interim financial results may not be indicative of results that
could  be  expected  for a full  year.  It is  suggested  that  these  condensed
consolidated  financial  statements be read in conjunction with the consolidated
financial  statements  and the notes  thereto  included in our Annual  Report to
Shareholders  for the fiscal year ended September 30, 2004. In our opinion,  the
unaudited  interim  financial   statements  include  all  normal  and  recurring
adjustments necessary for a fair statement of our financial position and results
of operations for the periods presented.


2.   SIGNIFICANT ACCOUNTING POLICIES

     Statement of Financial  Accounting  Standards ("SFAS") No. 123, "Accounting
for Stock-Based Compensation" allows companies the choice of either using a fair
value  method  of  accounting  for  options,   which  would  result  in  expense
recognition  for all options  granted,  or using an  intrinsic  value  method as
prescribed by Accounting  Principles  Board ("APB") Opinion No. 25,  "Accounting
for Stock Issued to Employees,"  with pro forma  disclosure of the impact on net
income (loss) of using the fair value option expense recognition method.

     We apply the recognition  and measurement  principles of APB Opinion No. 25
and  related  interpretations.  Accordingly,  no  compensation  costs  have been
recognized  in net income  from the  granting  of options  pursuant to our stock
option plans,  as all options  granted  under those plans had an exercise  price
equal to the market value of the underlying common stock on the date of grant.

     Had compensation costs been determined based on the fair value at the grant
dates  consistent  with the method of SFAS No. 123,  our net income and earnings
per share would have been reduced to the pro forma amounts  indicated  below (in
thousands, except for per share amounts):

     The fair value of grants made during the current fiscal year-to-date period
were estimated on the date of grant using the Black-Scholes option pricing model
with the  following  weighted-average  assumptions:  risk-free  interest  rate -
4.27%,  expected  volatility  - 35%,  expected  life - 6 years,  and no dividend
yield.

     In December 2004, the Financial  Accounting Standards Board ("FASB") issued
SFAS No.  123  (Revised  2004),  "Share-Based  Payment"  ("SFAS  123(R)").  This
Statement revises SFAS No. 123 by eliminating the option to account for employee
stock options under APB No. 25 and generally requires companies to recognize the
cost of employee services received in exchange for awards of equity  instruments
based   on  the  fair   value  on  the   grant   date  of  those   awards   (the
"fair-value-based"  method).  Originally,  SFAS No. 123R was to become effective
for public  entities as of the beginning of the first interim  reporting  period
that begins after June 15, 2005.  On April 14, 2005,  the SEC announced it would
permit companies to implement SFAS 123(R) at the beginning of their first fiscal
year beginning after June 15, 2005. Accordingly, we plan to adopt SFAS 123(R) on
October 1, 2005 and will use the modified prospective method without restatement
of prior  periods.  The impact of adopting SFAS 123(R) will be to record expense
for previously-issued but unvested employee stock options and any employee stock
options  that we issue  in the  future.  We  expect  the  dollar  impact  on our
financial statements to be consistent with the impact previously disclosed above
in the pro forma  disclosure  requirements  of SFAS No. 123,  beginning with the
first quarter of fiscal year 2006.

     In May 2005,  the FASB issued SFAS  No.154,  "Accounting  Changes and Error
Corrections - a replacement of APB Opinion No.20 and FASB Statement No.3," which
is effective  for  reporting a change in  accounting  principle for fiscal years
beginning  after  December 15, 2005.  The  Statement  changes the reporting of a
change in accounting  principle to require  retrospective  application  to prior
periods'  financial  statements,   except  for  explicit  transition  provisions
provided  for  in  new   accounting   pronouncements   or  existing   accounting
pronouncements, including those in the transition phase when SFAS No.154 becomes
effective. We will apply SFAS No.154 as required.

     Effective  October 1, 2004, we extended the remaining  depreciable  life of
the SEAHAWK from 2 months to 5 years, due to entry into a contract that extended
the rig's commercial  viability for up to 5 years. We believe that the change in
depreciable  life  provided and  continues  to provide a better  matching of the
revenues and expenses of this asset over its anticipated  remaining useful life.
We will  continue  to  depreciate  this rig on a  straight-line  method  for the
remainder of the extended period.  As a result of the change in depreciable life
from 2 months to 5 years,  depreciation expense was increased and net income was
reduced by  approximately  $0.2 million,  or $.01 per share, for the three month
period ended June 30, 2005, and depreciation  expense was reduced and net income
was  increased by  approximately  $0.6  million,  or $.04 per share for the nine
month period ended June 30, 2005.  Depreciation  expense  going  forward will be
higher than it otherwise  would have been  because if not for this  extension of
the SEAHAWK's  useful life, this asset would have been fully  depreciated in the
first quarter of fiscal year 2005.


5.   COMMITMENTS AND CONTINGENCIES

     We are party to a number of lawsuits which are ordinary, routine litigation
incidental  to our  business,  the  outcome  of which,  individually,  or in the
aggregate,  is not expected to have a material  adverse  effect on our financial
position, results of operations, or cash flows.

                                       13





6.   CAPITAL STOCK

     In  October  2004,  we sold in a public  offering  1,175,000  shares of our
common  stock at an  effective  net price  (before  expenses)  of $45.83 for net
proceeds of approximately $53.6 million. We used these proceeds and cash on hand
to repay  the $55  million  outstanding  as of  September  30,  2004  under  the
revolving portion of our senior secured credit facility.


7.   ATWOOD BEACON

     The ATWOOD BEACON  incurred  damage to all three legs and the derrick while
positioning  for a well  offshore  of  Indonesia  in July 2004.  The rig and its
damaged  legs were  transported  to the  builder's  shipyard  in  Singapore  for
inspections  and repairs.  At September  30, 2004,  the book basis of the ATWOOD
BEACON was reduced by $16.3 million  which was the estimated  reduction in value
caused by the  incident.  An insurance  receivable  totaling  $25.4  million was
recorded for such  estimated  damage,  as well as estimated  recovery  costs and
business interruption loss incurred through September 30, 2004.

     As of June 30, 2005,  all costs  incurred to date related to this  incident
had been reimbursed by the insurance  carrier with the exception of $0.1 million
which has since been  reimbursed.  During  fiscal year 2006, we plan to complete
the  remaining  work to restore the rig to its  pre-incident  condition at which
time we expect to  collect  the  remaining  $0.6  million  insurance  receivable
associated therewith.


8.   INCOME TAXES

     Virtually  all of our tax  provision  for each of the three months and nine
months ended June 30, 2005 and 2004  relates to taxes in foreign  jurisdictions.
Accordingly,  due to the low level of operating income in certain nontaxable and
deemed profit tax jurisdictions  during the nine months ended June 30, 2004, our
effective tax rate for fiscal year 2004 period exceeded the U.S. statutory rate.

     In December 2004, we received a $1.7 million tax refund in Malaysia related
to a previously  reserved tax receivable.  In addition,  a $1.0 million deferred
tax  benefit  was  recognized  in June 2005 due to the  filing,  and  subsequent
acceptance by the local tax authority,  of amended prior year tax returns. Also,
our operating income in certain  nontaxable and deemed profit tax  jurisdictions
during the three and nine  months  ended June 30, 2005 is  significantly  higher
when  compared  to the same  periods  in fiscal  year  2004.  As a  result,  our
effective tax rate for the current fiscal year periods were  significantly  less
than the U.S. statutory rate.

                     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  we  deem  reasonable.  We can  give  no  assurance  that  such
expectations and assumptions will prove to be correct,  and actual results could
differ materially from the information  presented  herein.  Our periodic reports
filed  with the SEC  should  be  consulted  for a  description  of risk  factors
associated with an investment in us.

MARKET OUTLOOK

     Effective  utilization of worldwide offshore drilling units today is around
97% compared to around 90% one year ago. High equipment utilization has resulted
in significantly  increasing dayrates.  Currently,  we have approximately 70% of
rig-days for fiscal year 2006 firmly committed.  For calendar year 2006, we have
approximately  55% of rig-days  firmly  committed.  Several of our drilling rigs
have current dayrate commitments that represent historically high dayrate levels
for those rigs while  operated  by us.  Revenues,  operating  cash flows and net
income for fiscal year 2005 are  expected to be  significantly  higher than they
were in fiscal  year  2004.  With our  current  dayrate  commitments,  operating
results for fiscal year 2006 should also reflect  significant  improvement  over
expected results for fiscal year 2005.

     During the quarter ended June 30, 2005, the SEAHAWK incurred  approximately
40 zero rate  days  before  returning  to work  offshore  Malaysia.  The  ATWOOD
SOUTHERN  CROSS  incurred  approximately  20 zero  rate  days at the end of that
quarter  while  it  was  being  prepared  for  its  relocation  to  the  Eastern
Mediterranean, and where it will return to work around mid-September,  2005. All
of our other six active  drilling  units were 100%  utilized  during the quarter
ended June 30, 2005.

     We remain  optimistic  about the long-term  outlook and fundamentals of the
offshore drilling market. For fiscal year 2006, the ATWOOD EAGLE, ATWOOD HUNTER,
VICKSBURG,  SEAHAWK  and  RICHMOND  have  contractually  committed  dayrates  of
$180,000, $125,000, $92,000, $68,430 and $45,000 respectively, which will be the
highest  dayrates  these units have ever received  while operated by us. With an
improved  market  environment,  a current  capital ratio to total debt of 22%, a
current annual capital  commitments for maintenance of our eight active drilling
units expected to only be $6 to $10 million and expected high utilization of our
drilling  units during the  remainder of fiscal year 2005 and all of fiscal year
2006,  we  anticipate  that our balance  sheet and  liquidity  will  continue to
strengthen.

RESULTS OF OPERATIONS

     Revenues  for the three and nine months ended June 30, 2005  decreased  10%
and increased 8%, respectively, compared to the three and nine months ended June
30, 2004. A comparative analysis of revenue by rig is as follows:

     The  average  dayrates  for the  RICHMOND  were  approximately  $33,000 and
$31,000 for the three and nine months ended June 30,  2005,  compared to average
dayrates  of  approximately  $27,000  and  $26,000 for the three and nine months
ended  June 30,  2004.  While  revenues  for the ATWOOD  HUNTER for the  current
quarter were  consistent  with the prior fiscal year quarter,  the  year-to-date
increase  is due to  approximately  100%  utilization  at a dayrate  of  $62,000
compared to  approximately  95 % utilization at dayrates  ranging from $40,000 -
$62,000 for the prior fiscal year-to-date period. Revenues for the ATWOOD FALCON
and VICKSBURG for the current  quarter and  year-to-date  period were relatively
consistent  for the same periods in the prior fiscal year.  The ATWOOD  BEACON's
revenue for the current  quarter was also  relatively  consistent with the prior
fiscal year quarter.  However, the increase in revenue for the nine months ended
June 30, 2005 was due to an average  dayrate of $67,000 which  includes 110 days
of loss of hire  insurance,  compared  to an average  dayrate  of  approximately
$56,000 for the nine months  ended June 30,  2004.  The decrease in revenues for
the ATWOOD SOUTHERN CROSS for the current quarter was due to  approximately  80%
utilization as the rig commenced its relocation to the Mediterranean during June
compared to 100% utilization in the prior fiscal year quarter while revenues for
the year-to-date periods were consistent. Utilization rates for the SEAHAWK were
approximately  60% and 80% for the three  month and nine  months  ended June 30,
2005,  respectively  as the rig was awaiting  commencement of its next contract,
while utilization during the prior fiscal year was 100%. The fiscal year-to-date
decrease also includes three months  amortization of deferred upgrade revenue of
approximately  $1.3  million  during the first  quarter of the prior fiscal year
compared to no  amortization  of such revenue  during the current fiscal year as
amortization of the upgrade revenue ended November 2003. The decrease in revenue
for the  ATWOOD  EAGLE  for the  current  quarter  was  due to  amortization  of
mobilization  revenues of  approximately  $2.7  million in the prior fiscal year
quarter compared to none in the current quarter.  Fiscal  year-to-date  revenues
were higher compared to the prior fiscal year-to-date period as the rig has been
100% utilized during the current fiscal year compared to approximately 60%

                                       16



utilization during the prior fiscal year as the rig was relocating to Australia.
Other  revenues  are higher than the prior fiscal year periods due to the recent
increase in activity with one of our managed platform rigs in Australia.

     Contract  drilling  costs for the three and nine months ended June 30, 2005
decreased 3% and increased 6%,  respectively,  as compared to the three and nine
months ended June 30, 2004. A comparative analysis of contract drilling costs by

     The increase in drilling  costs for the SEAHAWK and RICHMOND were primarily
due to higher repair and  maintenance  expenses  incurred on the rigs during the
three and nine months ended June 30, 2005  compared to the three and nine months
ended June 30, 2004.  Drilling  costs for the ATWOOD FALCON,  VICKSBURG,  ATWOOD
HUNTER,  ATWOOD SOUTHERN CROSS, and ATWOOD BEACON remained relatively consistent
for the current quarter and fiscal  year-to-date  period as compared to the same
periods in the prior  fiscal year with the  exception  of the decrease of fiscal
year-to-date  costs for the ATWOOD SOUTHERN CROSS.  That decrease was due to the
fact that the rig incurred approximately $1.6 million of boat towing costs while
relocating  from Egypt to India  during the  quarter  ended  December  31,  2003
compared to no such costs in the quarter ended  December 31, 2004.  The decrease
in drilling  costs for the ATWOOD  EAGLE  during the current  quarter was due to
several   factors.   We  amortized   ATWOOD  EAGLE   mobilization   expenses  of
approximately  $2.6 million in the prior fiscal year quarter compared to none in
the current fiscal year quarter. ATWOOD EAGLE fiscal year-to-date drilling costs
have  increased  due to an  approximate  $20,000 per day higher  salary  expense
attributable  to  additional  rig  personnel  required  due to  local  operating
requirements in Australia  during the current fiscal year and higher  Australian
labor costs in comparison to labor costs in West Africa, its location during the
first quarter of the prior fiscal year. Other drilling costs were higher for the
three and nine months ended June 30, 2005 due to the recent increase in activity
with  one  of  our  managed  platform  rigs  in  Australia.   The  prior  fiscal
year-to-date  period also  includes the  settlement of a dispute with a customer
which resulted in a reduction to drilling costs of approximately $600,000 and an
insurance premium refund of $450,000.

30

     Effective  October 1, 2004, we extended the remaining  depreciable  life of
the SEAHAWK from 2 months to 5 years,  as  discussed in Note 4 of our  condensed
consolidated financial statements, which resulted in the current quarter and the
fiscal year-to-date  reduction of depreciation  expense. The depreciable life of
this rig was extended  based upon entry into a contract  that extended the rig's
commercial  viability  for up to 5 years,  coupled  with our intent to  continue
marketing and operating the rig beyond 2 months.

     General  and  administrative  expenses  for the  current  fiscal  year have
increased  compared  to the prior  three and nine month  periods due to the fact
that $0.7 million in bonuses were paid during the current  fiscal year versus no
bonus payments in the prior fiscal year and due to increased  professional  fees
resulting  from  compliance  requirements  of the  Sarbanes-Oxley  Act of  2002.
Although the level of our outstanding debt has been reduced  significantly  from
the prior  fiscal  year,  interest  expense has only  decreased  slightly due to
rising interest rates.

     Virtually  all of our tax  provision  for each of the three and nine months
ended  June 30,  2005 and 2004  relates to taxes in  foreign  jurisdictions.  In
December  2004,  we received a $1.7 million tax refund in Malaysia  related to a
previously  reserved tax receivable.  In addition,  a $1.0 million  deferred tax
benefit was recognized in June 2005 due to the filing, and subsequent acceptance
by the local tax authority,  of amended prior year tax returns. As a result, our
effective tax rate for the current quarter and fiscal  year-to-date  period were
significantly  less than the U.S. statutory rate. The effective tax rate for the
current fiscal year is also significantly less when compared to the prior fiscal
year due to the items mentioned  above,  and due to a higher operating income in
certain   nontaxable   and  deemed  profit  tax   jurisdictions   during  fiscal
year-to-date  2005  when  compared  to the same  period  in  fiscal  year  2004.
Excluding any other discrete items that may be incurred, we expect our effective
tax rate to be approximately  25% for the fourth quarter of fiscal year 2005 and
10% for the whole of fiscal year 2005 as a whole.

 
                                       18




LIQUIDITY AND CAPITAL RESOURCES
 
     Due to the cyclical nature of the offshore drilling  industry,  maintaining
high equipment  utilization of our eight active drilling units in up, as well as
down,  cycles is a key factor in generating  cash to satisfy  current and future
obligations.  Since fiscal year 2000, net cash provided by operating  activities
ranged from a low of approximately  $14 million in fiscal year 2003 to a high of
approximately  $62  million  in fiscal  year  2001,  with net cash  provided  by
operating  activities in fiscal year 2004 of approximately $26 million. Net cash
provided by operating  activities  for the first nine months of fiscal year 2005
was  approximately  $37.9 million.  We expect that in fiscal year 2005, net cash
provided by operating  activities will be approximately $50 million for the full
fiscal  year  period.  Our  operating  cash  flows are  primarily  driven by our
operating  income,  which  reflects  dayrate  and rig  utilization.  With higher
dayrates and strengthening  market conditions,  we should have higher cash flows
and earnings in fiscal year 2005  compared to fiscal year 2004.  Currently,  our
existing  cash  commitments  for the  remainder  of fiscal year 2005 and beyond,
outside of funding current rig operations,  includes annual capital expenditures
of $6 to $10 million for  maintenance  of our eight active  drilling  rigs,  $16
million  upgrade of the  SEAHAWK  planned  in fiscal  year 2006 prior to the rig
commencing  working under its long-term  contract in West Africa,  and quarterly
repayments  of $9 million  under the term portion of our senior  secured  credit
facility. We expect to generate sufficient cash flows from operations to satisfy
these obligations.

     At June 30, 2005, we had $99 million outstanding under the term portion and
nothing  outstanding  under the $100  million  revolving  portion  of our senior
secured  credit  facility.  In October  2004,  upon  conclusion of our 1,175,000
common shares stock offering,  we repaid the $55 million then outstanding  under
the revolving  portion of our senior secured credit  facility with proceeds from
the offering and cash on hand. We currently  have  approximately  $99 million of
available  borrowing  capacity  and  with a debt to total  capitalization  ratio
currently  around  22%,  we expect to remain in  compliance  with all  financial
covenants  during the  remainder  of fiscal year 2005.  The  collateral  for our
senior secured credit facility consists primarily of preferred  mortgages on all
eight of our active drilling units (with an aggregate net book value at June 30,
2005  totaling  approximately  $385  million).  We are  required to pay a fee of
approximately  .80% per  annum  on the  unused  portion  of the  revolving  loan
facility and certain other  administrative  costs.  Effective  June 15, 2005, we
amended our senior  secured  credit  facility to clarify  covenants  relating to
insurance.

     The SEASCOUT,  a semisubmersible hull which could be converted and upgraded
to a  semisubmersible  tender assist vessel,  continues to be  cold-stacked.  We
expect that the cost to convert and  upgrade the  SEASCOUT  would range from $70
million to $80 million.  We have no current capital commitments on the SEASCOUT,
and we would not plan to undertake a conversion and upgrade unless an acceptable
contract  opportunity  has been secured and adequate  financing is in place.  We
continue to periodically  increase and adjust our planned  capital  expenditures
and financing of such expenditures in light of current market conditions.

     Our portfolio of accounts  receivable  is comprised of major  international
corporate  entities with stable payment  experience.  Historically,  we have not
encountered  significant  difficulty in collecting  receivables and typically do
not require  collateral for our receivables.  The insurance  receivable of $25.4
million at  September  30, 2004 and $0.6 million of the $1.1 million at June 30,
2005 relates to repairs made or to be made to the ATWOOD  BEACON.  During fiscal
year 2006,  we plan to  complete  the  remaining  work to restore the rig to its
pre-incident  condition  at which time we expect to collect the  remaining  $0.6
million insurance receivable associated therewith.

                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     We are exposed to market risk,  including  adverse change in interest rates
and foreign currency exchange rates as discussed below.

INTEREST RATE RISK

     With the  interest  rate on our  long-term  debt under our  current  credit
facilities at a floating rate, the outstanding  long-term debt of $99 million at
June 30, 2005  approximates  its fair value. The impact on annual cash flow of a
10%  change  in the  floating  rate  (approximately  50 basis  points)  would be
approximately  $0.5  million.  We did not  have any  open  derivative  contracts
relating to our floating rate debt as of June 30, 2005.

FOREIGN CURRENCY RISK

     Certain of our  subsidiaries  have monetary assets and liabilities that are
denominated in a currency other than their functional currencies.  Based on June
30,  2005  amounts,  a decrease  in the value of 10% in the  foreign  currencies
relative to the U.S. dollar from the prior fiscal year-end  exchange rates would
result in a foreign currency  transaction loss of approximately $0.3 million. We
did not have any open derivative  contracts relating to foreign currencies as of
June 30, 2005.

                             CONTROLS AND PROCEDURES


(a)      Evaluation of Disclosure Controls and Procedures

     Our management,  with the  participation of our Chief Executive Officer and
Chief Financial Officer,  evaluated the effectiveness of our disclosure controls
and procedures as of the end of the period covered by this report. Based on that
evaluation,  the Chief Executive  Officer and Chief Financial  Officer concluded
that our disclosure  controls and procedures as of the end of the period covered
by this report have been  designed and are  functioning  effectively  to provide
reasonable  assurance that the information required to be disclosed by us in our
periodic SEC filings is recorded, processed,  summarized and reported within the
time periods  specified in the SEC's rules,  regulations  and forms.  We believe
that a controls system, no matter how well designed and operated, cannot provide
absolute  assurance that the  objectives of the controls  system are met, and no
evaluation of controls can provide  absolute  assurance  that all control issues
and instances of fraud, if any, within a company have been detected.

(b)      Changes in Internal Control over Financial Reporting

     No change in our internal control over financial  reporting occurred during
the fiscal quarter  covered by this report that has materially  affected,  or is
reasonably  likely to materially  affect,  our internal  control over  financial
reporting.
