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


     This Form 10-Q for the  quarterly  period ended  December 31, 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



You  should  also read the risk  factors  set forth in our Form 10K for the
year ended September 30, 2005 filed with the Securities and Exchange Commission,
or SEC. 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.

                      PART I. ITEM 1 - FINANCIAL STATEMENTS
                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.       UNAUDITED INTERIM INFORMATION

     The unaudited interim  condensed  consolidated  financial  statements as of
December  31, 2005 and for each of the three month  periods  ended  December 31,
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, 2005. 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 generally accepted accounting
principles 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 year ended September 30,
2005. In our opinion,  the unaudited  interim financial  statements  reflect all
adjustments  (consisting of normal recurring  adjustments)  considered necessary
for a fair statement of our financial position and results of operations for the
periods presented.


2.       SHARE-BASED COMPENSATION

     Effective  October 1, 2005,  we adopted  Statement of Financial  Accounting
Standards No. 123(R),  "Share-Based Payment" ("SFAS 123(R)"), using the modified
prospective  application  transition  method.  Under  this  method,  stock-based
compensation  cost is measured at the grant date,  based on the calculated  fair
value of the award,  and is recognized as an expense over the requisite  service
period  (generally  the  vesting  period  of the  equity  grant).  In  addition,
stock-based compensation cost recognized includes compensation cost for unvested
stock-based awards as of October 1, 2005. Prior to October 1, 2005, we accounted
for share-based  compensation in accordance  with  Accounting  Principles  Board
Opinion No. 25,  "Accounting  for Stock Issued to Employees"  ("APB No. 25"). No
share-based employee compensation cost has been reflected in net income prior to
October 1, 2005. Before that date, we reported the entire tax benefit related to
the exercise of stock options as an operating cash flow. SFAS 123(R) requires us
to report the tax benefit from the tax deduction that is in excess of recognized
compensation costs (excess tax benefits) as a financing cash flow rather than as
an  operating  cash flow.  The  cumulative  effect of the  change in  accounting
principle from APB No. 25 to FAS 123(R) was not material.


                                       10



     We have a stock incentive plan, the 2001 Plan,  whereby 1,000,000 shares of
common stock may be issued to eligible  participants  in the form of  restricted
stock  awards or upon  exercise of stock  options  granted  pursuant to the 2001
Plan.  Awards of restricted  stock and grants of stock options may be made under
the 2001 Plan through September 5, 2011. As of December 31, 2005, 624,750 shares
are available  under the 2001 Plan for future  restricted  stock awards or stock
option  grants.  Options to purchase  517,550  shares are currently  outstanding
under the 2001 Plan and 41,000 shares of restricted stock have been issued under
the 2001 Plan.  Our board of directors  has approved  certain  amendments to our
2001 Plan,  subject to  shareholder  approval.  We have submitted an amended and
restated  version of our 2001 Plan to our  shareholders  for approval  which was
obtained at our annual shareholders meeting to be held on February 9, 2006.

     We have two other stock  incentive  plans under which there are outstanding
stock options.  There are outstanding  options to purchase  323,525 shares under
our 1996 Plan and 2,000 shares under a 1990 Plan; however, no additional options
or restricted stock will be awarded under either of these plans.  Only awards of
restricted  stock or stock  options  had been  granted  under  any of our  stock
incentive  plans as of December 31,  2005.  We deliver  newly  issued  shares of
common stock for restricted stock awards and upon exercise of stock options. All
stock incentive plans currently in effect have been approved by the shareholders
of our outstanding common stock.

     During  the  three  months  ended   December   31,  2005,   we   recognized
approximately  $0.9 million in share-based  compensation  expense which has been
included in our  statement of  operations in contract  drilling  expenses  ($0.2
million) and in general and  administrative  expenses ($0.7 million).  The total
income tax benefit recognized related to share-based  compensation for the three
months ended December 31, 2005 was approximately  $0.2 million.  The tax benefit
realized  from stock options  exercised  during the first quarter of fiscal year
2006 was $0.6  million.  The  impact of  adopting  FAS  123(R) had the effect of
decreasing  our net income and  earnings per share by $0.7 million and $0.04 per
basic and diluted  share for the quarter  ended  December 31, 2005. In addition,
the adoption had the effect of  decreasing  cash flows from  operations  by $0.6
million and increasing cash flows from financing  activities by $0.6 million for
the current  quarter  from that which  would have been  otherwise  reported.  We
recognize compensation expense on grants of share-based compensation awards on a
straight-line  basis over the  required  service  period for each  award.  As of
December 31, 2005, total  unrecognized  compensation cost related to share-based
compensation   awards  was   approximately   $9.9  million,   net  of  estimated
forfeitures,  which we expect to  recognize  over a weighted  average  period of
approximately 2.7 years.

Stock Options

     Under all stock  incentive  plans,  the exercise price of each stock option
equals the fair  market  value of one share of our  common  stock on the date of
grant, with all outstanding  options having a maximum term of 10 years.  Options
vest ratably over a period from the end of the first to the fourth year from the
date of grant  under the 2001  Plan and from the end of the  second to the fifth
year from the date of grant  under the 1996 and 1990  Plans.  Each option is for
the purchase of one share of our common stock.

     The per share weighted  average fair value of stock options  granted during
the three  months  ended  December  31,  2005 and 2004 was  $35.39  and  $20.44,
respectively.  We  estimated  the fair value of each stock option on the date of
grant using the Black-Scholes pricing model and the following assumptions:

                            Three Months Ended
                                December 31

Expected Life (Years)           6           6
Dividend Yield               None        None


     The average risk-free interest rate is based on the five-year U.S. treasury
security rate in effect as of the grant date. We determined  expected volatility
using a 6-year historical  volatility figure and determined the expected term of
the stock options using 15 years of historical data. The expected dividend yield
is based on the expected  annual dividend as a percentage of the market value of
our common stock as of the grant date.

Restricted Stock

Restrictions lapse at the end of the third year from the date of grant. We value
restricted  stock awards at the closing  market value of our common stock on the
date of grant.

     As of December  31,  2005,  none of the  restrictions  have lapsed on these
stock  awards.  Pursuant to the amended  and  restated  version of our 2001 Plan
approved by our shareholders on February 9, 2006, non-employee directors will be
automatically  granted  restricted  stock  awards as detailed in our  definitive
proxy  statement sent to our  shareholders  relating to our annual  shareholders
meeting and filed with the SEC on January 13, 2006.

     The  calculation  of diluted  earnings per share for the three month period

to 63,000 stock options because such options were  anti-dilutive.  These options
could potentially dilute basic EPS in the future.

     In October  2005, we sold our  semisubmersible  hull,  SEASCOUT,  for $10.0
million (net after certain  expenses) and our spare 15,000 P.S.I.  BOP Stack for
$15.0 million,  resulting in an aggregate gain of approximately $9.3 million for
both of these assets.  We had no operations  or revenues  associated  with these
assets prior to their sale.

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.

6.   INCOME TAXES

     Virtually  all of our tax  provision  for each of the  three  months  ended
December  31,  2005  and  2004  relates  to  taxes  in  foreign   jurisdictions.
Accordingly,  due to the high  level  of  operating  income  earned  in  certain
nontaxable  and deemed  profit tax  jurisdictions  during the three months ended
December 31, 2005,  our  effective tax rate for the first quarter of fiscal year
2006 is significantly less than the U.S. statutory rate.

                                       15




         During the first quarter of fiscal year 2005, we received a $1.7
million tax refund in Malaysia related to a previously reserved tax receivable.
In addition, we earned revenue from our loss of hire insurance coverage on the
ATWOOD BEACON in a zero tax jurisdiction. As a result, our effective tax rate
for the first quarter of fiscal year 2005 was significantly less than the U.S.
statutory rate.

                      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 our common stock.

RECENT EVENT

     Subsequent  to filing  our Form 8-K on  January  30,  2006  announcing  our
earnings  for the first  quarter of the fiscal  year 2006 of $0.97 and $0.94 per
basic and diluted  share,  respectively,  we  determined  that the tax provision
needed to be increased for the quarter ended December 31, 2005 by  approximately
$370,000 which decreased basic earnings per share by $0.03.  Diluted earning per
share,  however,  only  decreased  by $0.01 as the  effect of the tax  provision
increase was  partially  offset by an update in the number of shares used in the
diluted earnings per share calculation.  These changes reduced basic and diluted
earnings per share for the first quarter of fiscal year 2006 to $0.94 and $0.93,
respectively.

MARKET OUTLOOK

     There continues to be very strong demand for offshore  drilling  equipment,
with all of our eight drilling units having contractual dayrate commitments that
are the  highest  in their  respective  histories.  Currently,  we have  100% of
available  rig days for the  remainder  of  fiscal  year 2006  contracted,  with
contracted rig days for fiscal year 2007 and 2008 at 80% and 53%,  respectively.
A  comparison  of the average per day  revenues for fiscal year 2005 and for the
first quarter of fiscal year 2006 for each of our eight  drilling units to their
current highest contracted dayrate commitment is as follows:

     The  ATWOOD  HUNTER is  currently  working  offshore  Egypt at a dayrate of
$125,000 on a drilling  program that is expected to be completed in April or May
2006.  Immediately upon the rig completing its current drilling program, it will
commence a two year  drilling  program at dayrates of $240,000 to $245,000.  The
ATWOOD EAGLE is currently  working offshore  Australia at a dayrate of $160,000.
It has  contractual  commitments  offshore  Australia  at dayrates  ranging from
$150,000 to $420,000 (except for a one-well commitment remaining at a dayrate of
$89,000) that could keep the rig employed  through  fiscal year 2008. The ATWOOD
FALCON is currently working offshore Malaysia at a dayrate of $93,000.  It has a
contractual  commitment  offshore  Malaysia at dayrates  ranging from $93,000 to
$200,000  (except for a one-well  commitment  remaining at a dayrate of $53,000)
which could extend through the first half of fiscal year 2009. This  contractual
commitment  requires  the rig to undergo  an  upgrade to extend its water  depth
drilling  capabilities  from 3,700 feet to 5,000 feet. The customer will pay $24
million  of the cost of the  upgrade  along with  payment  of a $90,000  dayrate
during the  upgrade  period.  We expect to pay the  balance of $6 million of the
upgrade  out  of  cash  flow.  The  ATWOOD  SOUTHERN  CROSS  has  completed  its
approximate $7 million  equipment  upgrade and has commenced  drilling  offshore
Italy at a dayrate of  $70,000.  The rig has  drilling  commitments  at dayrates
ranging from $70,000 to $125,000  that should extend to the end of calendar year
2006.  Currently,  the ATWOOD BEACON is working offshore Vietnam at a dayrate of
$77,000  on a drilling  program  that could  extend  into the fourth  quarter of
fiscal year 2006.  Immediately upon completion of its current drilling  program,
the rig will make a brief stop in  Singapore  to have its final  section of legs
installed and will then be relocated to India to commence a 25-month contract at
dayrates ranging from $113,000 to $133,500.  The VICKSBURG is currently  working
offshore  Southeast  Asia at a dayrate of $87,000.  It has contract  commitments
offshore  Southeast Asia at dayrates ranging from $82,000 to $94,500 that should
extend into the third quarter of fiscal year 2007.  The SEAHAWK,  with a current
dayrate of $50,000,  is scheduled  to enter a shipyard in Southeast  Asia during
the  second  quarter  of fiscal  year 2006 to  undergo  a $16  million  upgrade.
Following  the upgrade,  the rig will be  relocated  to offshore  West Africa to
commence a 730 day (plus four six-month  options)  drilling program at a dayrate
of $68,430.  The rig could be off dayrate for  approximately  five months  while
undergoing  the upgrade and relocation to offshore  Africa.  Our only rig in the
U.S. Gulf of Mexico, the RICHMOND, has a current contract commitment at dayrates
ranging from $45,000 to $80,000 which could extend to May/June 2007. Its current
dayrate is $45,000.

     With the  current  strong  market  environment  supporting  high  equipment
utilization and historical high dayrates for all of our eight drilling units, we
expect  significantly  improved cash flows and operating  results in fiscal year
2006  compared to fiscal year 2005.  Our  current  total debt to  capitalization
ratio  (debt/(debt  + equity)) is 18% as of December 31, 2005 compared to 20% as
of September  30, 2005.  As we pay off the term portion of our Credit  Facility,
this  ratio  will  continue  to  decline  unless  we have  borrowings  under the
revolving  portion of our Credit  Facility  which exceed the amounts we pay down
under the term portion of our Credit Facility.  We do not expect to borrow under
the revolving  portion of our Credit  Facility  unless we identify an acceptable
growth  opportunity,  and only to the extent we do not fund any required amounts
out of cash flow.

     We continue to evaluate growth opportunities,  and on January 31, 2006, our
wholly-owned  subsidiary,  AOPL, executed a letter of intent with Keppel AmFELS,
Inc.  for the  construction  of a mobile  self-elevating  LeTourneau  SUPER  116
Jack-up. In conjunction  therewith,  AOPL has also secured an option to purchase
from  Letourneau,  Inc.  a  SUPER  116  KIT  which  will  be  required  for  the
construction  of  the  new  rig.  If  constructed,   the  new  rig  will  be  an
ultra-premium class jack-up, suited for operations throughout most of the world.


                                       18



     The new rig would be constructed at the Keppel AmFELS yard in  Brownsville,
Texas,  and delivery is expected to occur no later than September 30, 2008. AOPL
estimates the total cost of construction (including  administrative and overhead
costs and  capitalized  interest) would be between $150 million to $160 million,
depending  upon  the  possible  enhancements,  and  subject  to  any  additional
modifications  which would be addressed via change orders.  We expect to finance
the new rig from expected  cash on hand  balances  and, if  necessary,  from the
revolving portion of our Credit Facility.

     The  construction  of the new rig is  subject  to  execution  of  customary
definitive  agreements  with Keppel  AmFELS and  LeTourneau.  The new rig is not
presently  under  contract  and upon  delivery,  would be our ninth owned mobile
offshore drilling unit.

     The  increase  in revenue  for the ATWOOD  HUNTER was due to starting a new
contract  offshore  of Egypt  approximately  November  1, 2005 at a  dayrate  of
$125,000  while  earning a dayrate of $62,000 for the first month of fiscal year
2006 and all of the last quarter of fiscal year 2005. The ATWOOD  SOUTHERN CROSS
earned $2.9  million of  mobilization  revenue  amortization  during the current
quarter compared to none in the prior year quarter.  This increase was partially
offset by  approximately  50%  utilization  at $60,000  per day during the first
quarter of fiscal  year 2006  compared  to 100%  utilization  at $40,000 per day
during the first  quarter of fiscal year 2005.  The  increase in revenue for the
RICHMOND  was due to an increase in average  dayrate  from  $29,000 in the prior
year quarter to $42,000 in the current year quarter. The average dayrate for the
VICKSBURG  for the first  quarter  of fiscal  year 2006 was  $73,000  as the rig
started a new  contract  offshore  Myanmar at  $92,000  per day  compared  to an
average  dayrate of $64,000 during the first quarter of fiscal year 2005.  First
quarter of fiscal year 2006  revenues for the  SEAHAWK,  ATWOOD EAGLE and ATWOOD
BEACON were  comparable  to the same period for in the prior year.  Revenues for
the ATWOOD  FALCON  decreased in the first  quarter of fiscal year 2006 due to a
decrease  in the average  dayrate  from  $84,000 to $74,000 as the rig was,  and
still is, drilling the final well of a prior contractual commitment at a reduced
dayrate offshore  Malaysia.  As one of our managed platform rigs in Australia is
scheduled to commence a new drilling program during calendar year 2006,  service
activities for our management contracts have increased accordingly.

     Contract  drilling  costs for the three  months  ended  December  31,  2005
increased 34% compared to the three months ended  December 31, 2004. An analysis
of contract drilling costs by rig is as follows:

     The increase in drilling costs for the ATWOOD  SOUTHERN CROSS resulted from
$2.8 million of mobilization expense amortization in the first quarter of fiscal
year 2006,  while there was none  during the first  quarter of fiscal year 2005.
Before  relocating to its next  contract,  the VICKSBURG  entered a shipyard for
approximately 5 days during the current  quarter to undergo planned  inspections
and maintenance, which accounts for its increase in drilling costs. The increase
in  drilling  costs for the  ATWOOD  HUNTER,  ATWOOD  EAGLE,  ATWOOD  FALCON and
RICHMOND are primarily  attributable to 3 areas:  rising  personnel costs due to
wage increases,  rising  insurance costs due to increased  premiums and increase
repairs and maintenance expenses due to the amount and timing of various repairs
and  maintenance  projects.  The  SEAHAWK  and ATWOOD  BEACON  also  experienced
increased  personnel  and  insurance  costs,  but  these  costs  were  offset by
decreased  repairs  and  maintenance  expenses  when  compared to the prior year
quarter. As previously mentioned,  one of our managed platform rigs in Australia
is scheduled to commence a new drilling  program during  calendar year 2006, and
service  activities  for our management  contracts  have increased  accordingly.
Other  drilling  costs have  increased  due to the  recording of $0.2 million of
stock option compensation expense for field personnel during the current quarter
compared to none in the prior year quarter.

December 31, 2005  compared to the three  months  ended  December 31, 2005 is as

     In accordance with our company policy, no depreciation expense was recorded
during the month of December for the SOUTHERN  CROSS as the rig was undergoing a
life enhancing  upgrade whereby the useful life of the rig will be extended from
approximately 2 to 5 years in early calendar year 2006.


                                       21



     General and  administrative  expenses for the first  quarter of fiscal year
2006 increased  compared to the first quarter of the prior fiscal year primarily
due recording  approximately $0.7 million of stock option compensation  expense,
an  approximate  $0.6 million  increase in annual bonus  compensation,  and $0.8
million  higher  professional  fees  primarily  related  to  Sarbanes-Oxley  Act
compliance fees. We expect our general and administrative  expenses to remain at
a higher level than reported in prior  periods due to stock option  compensation
expense (refer to Note 2). 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  months  ended
December  31,  2005  and  2004  relates  to  taxes  in  foreign   jurisdictions.
Accordingly,  due to the high  level  of  operating  income  earned  in  certain
nontaxable  and deemed  profit tax  jurisdictions  during the three months ended
December 31, 2005,  our  effective tax rate for the first quarter of fiscal year
2006 is significantly  less than the U.S.  statutory rate.  However this rate is
higher when compared to the prior year quarter as we received a $1.7 million tax
refund in Malaysia  related to a previously  reserved tax receivable  during the
first  quarter of fiscal year 2005.  Excluding  any  discrete  items that may be
incurred, we expect our effective tax rate to be approximately 10-15% for fiscal
year 2006.

     Looking  forward,  we  expect  to  reverse a $1.8  million  tax  contingent
liability in the third  quarter of fiscal year 2006 due to the  expiration  of a
statute of limitations in a foreign jurisdiction. If this occurs, it will reduce
our tax provision in that quarterly period.

LIQUIDITY AND CAPITAL RESOURCES

     Since we operate in a very cyclical  industry,  maintaining  high equipment
utilization in up, as well as down, cycles is a key factor in generating cash to
satisfy current and future obligations.  For fiscal years 2000 through 2005, net
cash provided by operating  activities ranged from a low of approximately  $13.7
million in fiscal year 2003 to a high of  approximately  $62.3 million in fiscal
year 2001.  Our  operating  cash  flows are  primarily  driven by our  operating
income, which reflects dayrates and rig utilization.  With currently having 100%
and 80% of our available  operating rig days committed for fiscal years 2006 and
2007,  respectively,  at historically high dayrates,  we anticipate  significant
improvement in cash flows and earnings during fiscal years 2006 and 2007.  Other
than our expected capital  expenditures of $60 million to $65 million for fiscal
year 2006,  the only  additional  firm cash  commitment  for  fiscal  year 2006,
outside of funding current rig operations,  is our required quarterly repayments
under the term portion of our senior  secured  Credit  Facility which will total
$36 million for fiscal year 2006.  We expect to generate  sufficient  cash flows
from operations to satisfy these obligations.

     If AOPL enters into a definitive agreement to construct the newbuild mobile
self-elevating LeTourneau SUPER 116 Jack-up, our capital expenditures for fiscal
year 2006 will  increase  by  approximately  $9 million in  connection  with the
exercise  of the  option  to  purchase  the  related  SUPER  116  KIT and by any
additional amounts owed under the definitive construction agreement,  which will
not be  determined  if and until AOPL  enters into the  definitive  construction
agreement.  We expect to  finance  the new rig from  expected  cash  flows  from
operations and, if necessary, from the revolving portion of our Credit Facility.


                                       22



     As of December 31,  2005,  we only have $81 million  outstanding  under the
term portion of our Credit Facility, with approximately $99 million of available
borrowing  capacity  under the $100  million  revolving  portion  of our  Credit
Facility.  We are in  compliance  with all  financial  covenants at December 31,
2005,  and expect to remain in compliance  with all financial  covenants  during
fiscal year 2006. Aside from the financial covenants,  no other provisions exist
in the Credit  Facility that could result in  acceleration  of the April 1, 2008
maturity date.

     At December 31,  2005,  the  collateral  for our Credit  Facility  consists
primarily of preferred mortgages on all eight of our active drilling units (with
an aggregate  net book value at December 31, 2005  totaling  approximately  $380
million). We are not required to maintain compensating balances; however, we are
required to pay a fee of approximately  0.70% per annum on the unused portion of
the revolving loan facility and certain other administrative costs.

     In  October  2005,  we sold our  semisubmersible  hull,  SEASCOUT,  for $10
million (net after certain  expenses) and our spare 15,000 P.S.I.  BOP Stack for
approximately  $15  million.  The  gain on the  sales of  these  assets  totaled
approximately  $9.3  million in the  aggregate.  The $25.2  million in cash from
these sales has  increased  our  current  cash and cash  equivalents  on hand to
approximately $43.7 million as of December 31, 2005.

     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 $0.6
million at December 31, 2005 relates to repairs 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
associated remaining $0.6 million insurance  receivable.  We have a $0.1 million
allowance for doubtful accounts at December 31, 2005 due to a delinquent account
with one specific client.

                                                                 PART I. ITEM 3

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

     We are exposed to market risk,  including adverse changes 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 Credit Facility at a
floating  rate,  the  outstanding  long-term debt of $81 million at December 31,
2005 approximates its fair value. The impact on annual cash flow of a 10% change
in the floating rate (approximately 60 basis points) would be approximately $0.5
million,  which  we do not  believe  to be  material.  We did not  have any open
derivative contracts relating to our floating rate debt at December 31, 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
December  31,  2005  amounts,  a  decrease  in the  value of 10% in the  foreign
currencies  relative to the U.S.  dollar from the year-end  exchange rates would
result in a foreign currency  transaction  loss of  approximately  $0.4 million.
Thus,  we consider our current risk exposure to foreign  currency  exchange rate
movements,  based on net cash flows, to be immaterial.  We did not have any open
derivative contracts relating to foreign currencies at December 31, 2005.

                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
                             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, process, 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.
