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


     This Form 10-Q for the  quarterly  period  ended  March 31,  2006  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, upgrade and repair 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
March 31, 2006,  and for each of the three and six month periods ended March 31,
2006 and 2005, 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.
We suggest 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.       CAPITAL STOCK

     On March 2, 2006, the Board of Directors declared a two-for-one stock split
of our common stock  effected in the form of a 100% common stock  dividend.  All
shareholders of record on March 24, 2006 received one additional share of common
stock for each share held on that date.  The  additional  shares of common stock
were distributed in the form of a stock dividend on April 7, 2006. All share and
per  share  amounts  in  the  accompanying   condensed   consolidated  financial
statements  and related  notes have been adjusted to reflect the stock split for
all periods presented.


3.       SHARE-BASED COMPENSATION

     Effective  October 1, 2005,  we adopted  Statement of Financial  Accounting
Standards No. 123(R),  "Share-Based Payment", or 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",  or 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.


                                       10

     Under our Amended and Restated 2001 Stock Incentive Plan, or the 2001 Plan,
up to 2,000,000 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. We also have
another stock incentive  plan, the 1996 Plan,  under which there are outstanding
stock  options.  However,  no  additional  options or  restricted  stock will be
awarded under the 1996 plan.

     A summary of share and stock option data for our two stock  incentive plans
as of March 31, 2006 is as follows:

                                                       2001           1996

Outstanding restricted stock awards                     77,600             -



     Awards of  restricted  stock and stock options have both been granted under
our stock  incentive  plans as of March 31, 2006. 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.

     The impact of  adopting  SFAS  123(R) has had the  following  effect on our
consolidated financial statements (in thousands, except per share amounts):

     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  March  31,  2006,  total  unrecognized   compensation  cost  related  to
share-based compensation awards was approximately $8.8 million, net of estimated
forfeitures,  which we expect to  recognize  over a weighted  average  period of
approximately 2.5 years.


                                       11



Stock Options

     Under our 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 Plan. 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  six  months   ended  March  31,  2006  and  2005  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:

                               Six Months Ended
                                    March 31,
                           ------------------------
                                  2006        2005
                           ------------------------
Risk-Free Interest Rate          4.46%       4.27%
Expected Volatility                42%         35%
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.

     A summary of stock  option  activity  during the six months ended March 31,
2006 is as follows:

Restricted Stock

     We have also  awarded  restricted  stock to  certain  employees  and to our
non-employee directors.  The awards of restricted stock to employees are subject
to three year vesting,  and all  restricted  stock awards to date are restricted
from transfer for three years form the date of grant. We value  restricted stock
awards at the closing market value of our common stock on the date of grant.

     A summary of restricted  stock  activity for the six months ended March 31,
2006, is as follows:


                                                                    Aggregate

     As of March 31, 2006, none of the  restrictions  have lapsed on these stock
awards. Pursuant to the amendments to our 2001 Plan approved by our shareholders
on February 9, 2006,  during the quarter ended March 31, 2006, our  non-employee
directors were 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.  These
restricted  stock  awards  resulted  in 4,220  shares of our common  stock being
issued to our non-employee directors.

     The  calculation of diluted  earnings per share for the three and six month

related to 101,000 stock options because such options were anti-dilutive.  These
options could potentially dilute basic earnings per share 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.

6.      INCOME TAXES

     Virtually  all of our tax  provision  for each of the three and six  months
ended  March  31,  2006 and 2005,  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 and six months
ended  March  31,  2006,  our  effective  tax rate for the  second  quarter  and
year-to-date  period of fiscal  year  2006 is  significantly  less than the U.S.
statutory rate.

     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 three and six months ended March 31, 2005, was  significantly  less than
the U.S. statutory rate.


7.      COMMITMENTS AND CONTINGENCIES

     On May 3, 2006,  we received  notice  from the  Malaysian  tax  authorities
regarding  alleged   non-compliance  with  withholding  tax  provisions  of  the
Malaysian  Income  Tax Act for years of  assessment  2001 to 2004.  The  alleged
under-withholding  of tax approximates $2.1 million,  which is subject to a 100%
penalty.  We  believe  that  we are  in  compliance  with  all  withholding  tax
provisions of the Malaysian  Income Tax Act for years of assessment 2001 through
2004  and,  thus,  no  additional  withholding  taxes  are  payable.  We plan to
vigorously  contest these assertions by the Malaysian tax authorities.  While we
cannot  predict  or  provide   assurance  as  to  the  final  outcome  of  these
allegations,  we do not  expect  them to have a material  adverse  effect on our
consolidated financial position, results of operations or cash flows.

     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.

September  30,  2005,  should be  consulted  for a  description  of risk factors
associated with an investment in our common stock.


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 years 2007 and 2008 at 95% and 65%, respectively.
A  comparison  of the average per day  revenues for fiscal year 2005 and for the
first six  months 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  under a  two-year  contractual
commitment   with  Woodside   Energy  Limited   ("Woodside")  at  a  dayrate  of
$240,000/$245,000.  Woodside  farmed-out the first two wells to be drilled under
this commitment to Burullus Gas ("BG").  The rig is currently drilling the first
well under the BG  commitment  and is expected  to complete  the BG work in June
2006.  Following the  completion of this work the rig is expected to be moved to
sheltered water offshore Egypt to undergo certain planned maintenance (estimated
to take two days) prior to being relocated to Mauritania to commence working for
Woodside.  The ATWOOD EAGLE has contractual  commitments offshore Australia with
Woodside  and BHP  Billiton  Petroleum  at  dayrates  ranging  from  $150,000 to
$180,000  (except for a one-well  commitment  at a dayrate of $109,000  which is
expected  to be drilled in the  fourth  quarter of fiscal  year 2006) that could
extend to the end of fiscal year 2007. Immediately following the completion this
work, the rig has a one-well  commitment at a dayrate of $360,000 and a one-year
commitment at a dayrate of $420,000; however, before the middle of October 2006,

                                       17


     this  one-year  commitment  could  be  extended  to a  two  or  three  year
commitment  at a dayrate  of  $405,000.  The  ATWOOD  FALCON  has a  contractual
commitment  offshore  Malaysia  with Shell that extends to July 2009 at dayrates
ranging between $90,000 and $200,000.  This contractual  commitment requires the
rig to undergo an upgrade to extend its water depth drilling  capabilities  from
3,700 to 5,000 feet. The customer is contractually  obligated to pay $24 million
of the upgrade costs  (expected to be around $32 million)  along with payment of
approximately  $90,000 per day during the upgrade  period.  The ATWOOD  SOUTHERN
CROSS is currently  working offshore Italy at a dayrate of $70,000 on a drilling
program  that is  expected  to extend  into  September  2006.  Immediately  upon
completion of this drilling program,  we expect to relocate the rig to the Black
Sea to work for three  customers at dayrates  ranging from $125,000 to $290,000.
This work could  extend into the first  quarter of fiscal year 2008.  Currently,
the  ATWOOD  BEACON is  working  offshore  Vietnam  at a dayrate  of  $77,000 to
$110,000 on a drilling program that could extend to September 2006.  Immediately
upon  completion  of its  current  drilling  program,  we plan to have the final
section of legs installed on the ATWOOD BEACON at a shipyard in Singapore before
relocating  to India to commence a 25-month  contract at dayrates  ranging  form
$113,000 to $133,500. The VICKSBURG is currently working offshore Southeast Asia
at a dayrate of $87,000.  It has  contract  commitments  offshore  Malaysia  and
Cambodia at dayrates ranging from $82,000 to $94,500 that should extend into the
fourth  quarter  of fiscal  year  2007.  Immediately  upon  completion  of these
commitments,  the rig has a  two-year  commitment  in  Thailand  at a dayrate of
$154,000. The SEAHAWK is currently in a shipyard in Southeast Asia undergoing an
upgrade expected to cost around $20 million.  Following this upgrade, the rig is
expected to be  relocated  to offshore  West  Africa to commence  (estimated  in
August  2006) a 730 day (plus four  six-month  options)  drilling  program at an
operating  dayrate of  $68,430.  Our only rig in the U.S.  Gulf of  Mexico,  the
RICHMOND,  has a current  contract  commitment which could extend into the third
quarter of fiscal year 2007.  After  completing its current well at a dayrate of
$45,000,  all remaining  firm work under this contract is expected to be drilled
at a dayrate of $80,000.

     The current strong market environment is not only supporting high equipment
utilization  and historical  high dayrates for all of our eight drilling  units,
but also has resulted in a significant increase in our operating costs. Included
in the ATWOOD  SOUTHERN  CROSS'  total  operating  costs for the quarter and six
months ended March 31, 2006 are amortized mobilization costs of $6.0 million and
$8.8 million, respectively, compared to none for the same periods in fiscal year
2005.  For the  second  half of fiscal  year 2006,  we  currently  expect  daily
operating  costs for our bottom  supported  units (the  RICHMOND,  VICKSBURG and
ATWOOD  BEACON) to be around  $30,000 per day.  For the  remainder of the fiscal
year,  we  expect  daily  operating  costs  for the  ATWOOD  FALCON to be around
$40,000,  the ATWOOD  HUNTER to be between  $45,000 and $50,000,  and the ATWOOD
SOUTHERN CROSS to be between  $40,000 and $45,000.  We expect the ATWOOD EAGLE's
daily  operating  costs to  average  between  $75,000  and  $80,000.  The  daily
operating  costs of the SEAHAWK when it returns to work in August 2006  offshore
West  Africa is  expected to average  between  $35,000 and $40,000 and  possibly
higher during initial  start-up.  Despite the anticipated  increase in operating
costs, we expect our operating  margin for fiscal year 2006 to be  approximately
50%.

     We continue to evaluate  growth  opportunities,  and on March 1, 2006,  our
wholly-owned subsidiary,  Atwood Oceanics Pacific Limited, executed a definitive
construction  agreement  with Keppel  AmFELS,  Inc.  to  construct a mobile self
elevating  LeTourneau  SUPER  116E  design  jack-up.   This  new  rig  is  being
constructed in Brownsville, Texas, with delivery expected to occur no later than
September  30,  2008.  We  estimate  the total cost of  construction  (including
administrative   and  overhead   costs  and   capitalized   interest)   will  be
approximately around $160 million. A copy of the construction agreement is filed


                                       18


as Exhibit 4.2  hereto.  We intend to finance  the  construction  of the new rig
primarily from expected cash on hand balances,  however,  if and when necessary,
the $100  million  revolving  portion of our Credit  Facility  may provide  some
funding for the new rig. As of May 10, 2006 and taking into  account a borrowing
in April 2006, we have $10 million  outstanding  under the revolving  portion of
our Credit Facility.

     The ATWOOD SOUTHERN CROSS recognized $5.2 million and $8.1 million from the
amortization of up front mobilization fees which were previously received during
the three months and six months ended March 31, 2006,  respectively  compared to
none in the prior fiscal year. The increase in revenues for the current  quarter
was also due to rig utilization of approximately 90% at $70,000 per day compared
to  approximately  85%  utilization at an average  dayrate of $36,000 during the
second  quarter of fiscal year 2005.  The increase for the current  year-to-date
period  was also  due to rig  utilization  of  approximately  70% at an  average
dayrate of $68,000  compared  to  approximately  90%  utilization  at an average
dayrate of $38,000 during the prior fiscal year-to-date  period. The increase in
revenue for the three and six months ended March 31, 2006, for the ATWOOD HUNTER
was  primarily  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 prior  fiscal  year.  The
increase in revenue for the current quarter and year-to-date  period ended March
31, 2006,  for the ATWOOD  EAGLE was also due to starting a new contract  during
the current  quarter at dayrates  ranging from  $150,000 to $180,000  while only
earning  an  average  dayrate of  $105,000  for the second  quarter of the prior
fiscal year. The increase in revenue for the VICKSBURG was due to an increase in
average  dayrates from $62,000 and $63,000  during the quarter and  year-to-date
period ended March 31,  2005,  respectively,  to $85,000 and $80,000  during the
quarter and  year-to-date  period ended March 31, 2006.  The increase in revenue
for the  RICHMOND was also due to an increase in average  dayrates  from $30,000
during each of the three and six months ended March 31, 2005,  respectively,  to
$45,000 and $43,000 during the three and six months ended March 31, 2006. During
the current  quarter,  the ATWOOD  BEACON  earned  $78,000  per day  compared to
$66,000  during the second  quarter  of the prior  fiscal  year while the ATWOOD
FALCON earned  $73,000 per day at 100%  utilization  during the current  quarter
compared to $68,000 at  approximately  80% utilization for the comparable  prior
year quarter.  Second quarter and year-to-date fiscal year 2006 revenues for the
SEAHAWK were  comparable to the same periods in the prior fiscal year. As one of
our managed  platform rigs in Australia  commenced a new drilling program during
the current  quarter,  service  activities for our management  contracts for the
three and six months ended March 31, 2006 have increased accordingly.

     Contract  drilling costs for the three and six months ended March 31, 2006,
increased 58% and 46%, respectively,  compared to the three and six months ended
March 31, 2005. An analysis of contract drilling costs by rig is as follows:

     In  addition  to the items  discussed  below,  the  increase  in  fleetwide
drilling costs was primarily attributable to three 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 increase in drilling costs for the
ATWOOD  SOUTHERN  CROSS also  resulted  from $6.0  million  and $8.8  million of
mobilization  expense amortization in the first quarter and year-to-date periods
of fiscal  year 2006,  while there was none during the prior  fiscal  year.  The
increase in drilling  costs for the ATWOOD  HUNTER also  includes  higher  agent
commissions  due to increased  revenues for the three and six months ended March
31, 2006,  compared to the three and six months ended March 31, 2005.  Operating
costs for the ATWOOD  FALCON were lower  during the second  quarter of the prior
fiscal year, due to a ten day  mobilization to Japan.  Before  relocating to its
next  contract,  the VICKSBURG  entered a shipyard for  approximately  five days
during  the  first  quarter  of the  current  fiscal  year  to  undergo  planned
inspections and  maintenance.  The decrease in drilling costs for the SEAHAWK is
primarily due to  approximately  one month of lower  operating  costs during the
current  quarter as the rig  entered a shipyard  in  Malaysia  for an upgrade in
preparation for its next contract in West Africa. As previously  mentioned,  one
of our managed  platform  rigs in  Australia  commenced a new  drilling  program
during current quarter,  and service activities for our management contracts for
the three and six months ended March 31, 2006, have increased accordingly. Other
drilling  costs for the  year-to-date  period  ended March 31,  2006,  have also
increased  due to the  recording of $0.3  million of stock  option  compensation
expense for field personnel  during the current quarter  compared to none in the
prior fiscal year.

     In accordance with our company policy, no depreciation expense was recorded
during  the month of  December  2005 and part of January  2006 for the  SOUTHERN
CROSS as the rig was undergoing a life enhancing upgrade whereby the useful life
of the rig was extended from approximately two to five years in January 2006.

     General and administrative expenses for the second quarter and year-to-date
period  of  fiscal  year 2006  increased  compared  to the  second  quarter  and
year-to-date   period  of  the  prior  fiscal  year   primarily   due  recording
approximately  $1.3  million  and  $2.0  million  of stock  option  compensation
expense,  respectively.  Year-to-date  amounts for the current  fiscal year also
include an approximate $0.6 million increase in annual bonus  compensation,  and
$1.2 million increase in professional  fees primarily  related to Sarbanes-Oxley
Act compliance  and higher audit 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 as described in Note 3 to our unaudited  financial
statements  included in this report.  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 six  months
ended  March  31,  2006 and 2005,  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 current  quarter and
year-to-date  period  ended  March 31,  2006,  our  effective  tax rate for both
periods of approximately 15% is significantly less than the U.S. statutory rate.
Our effective tax rate for the six months ended March 31, 2005 of  approximately
6% resulted  primarily from receiving  during the first quarter of first quarter
of  fiscal  year  2005 a $1.7  million  tax  refund  in  Malaysia  related  to a
previously  reserved tax  receivable.  Excluding any discrete  items that may be
incurred, we expect our effective tax rate to be approximately 10-15% for fiscal
year 2006.


                                       22



     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.  In addition,  there are certain events in other foreign
jurisdictions,  relating  to prior  fiscal  years,  that may  also  result  in a
favorable  tax effect  during the current  fiscal  year.  If any of these events
occur, we will reduce our tax provision in the applicable  quarterly period. See
also "Recent Development" in this Part I, Item 2.


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 95% 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 $90 million to $95 million (including
funding for the  construction  of the new jack-up rig), 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  most of
these  obligations;  however,  some  funding from the  revolving  portion of our
Credit Facility may be required.

     As of March 31, 2006, we had $72 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;
however,  in April 2006, we borrowed $10 million under the revolving  portion of
our Credit Facility. We are in compliance with all financial covenants under our
Credit  Facility at March 31, 2006, and expect to remain in compliance  with all
financial  covenants  during the  remainder of 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 March 31,  2006  totaling  approximately  $376
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  increased our cash and cash  equivalents  on hand to  approximately
$43.7  million at December 31, 2005;  however,  with  approximately  $25 million
expended  to-date on  construction of the new jack-up rig and  approximately  $6
million  on  the  ATWOOD  SOUTHERN  CROSS  equipment  upgrades,  cash  and  cash
equivalents on hand declined to approximately $23 million at March 31, 2006.


                                       23



     Our accounts receivable have increased by $17.2 million since September 30,
2005, primarily due to our increased rig utilization,  higher dayrates, and also
due to winding down contracts with certain customers.  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. We have a $0.4 million allowance for doubtful accounts at March 31,
2006 relating to one specific client.

     Our accrued  liabilities have increased by $9.3 million since September 30,
2005,  primarily due to purchases related to the current upgrade in progress for
the SEAHAWK compared no upgrades in progress at prior fiscal year end.


RECENT DEVELOPMENT

     On May 3, 2006,  we received  notice  from the  Malaysian  tax  authorities
regarding  alleged   non-compliance  with  withholding  tax  provisions  of  the
Malaysian  Income  Tax Act for years of  assessment  2001 to 2004.  The  alleged
under-withholding  of tax approximates $2.1 million,  which is subject to a 100%
penalty.  We  believe  that  we are  in  compliance  with  all  withholding  tax
provisions of the Malaysian  Income Tax Act for years of assessment 2001 through
2004  and,  thus,  no  additional  withholding  taxes  are  payable.  We plan to
vigorously  contest these assertions by the Malaysian tax authorities.  While we
cannot  predict  or  provide   assurance  as  to  the  final  outcome  of  these
allegations,  we do not  expect  them to have a material  adverse  effect on our
consolidated financial position, results of operations or cash flows.

                                 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   debt  of  $72  million  at  March  31,  2006
approximates  its fair value.  The impact on annual cash flow of a 10% change in
the floating rate  (approximately  70 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 March 31, 2006.

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 March
31,  2006  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  $0.6  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 March 31, 2006.

(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 effective at the reasonable assurance level so 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 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.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     Our annual meeting of  shareholders  was held on February 9, 2006, at which
the  shareholders  voted on the election of six director  nominees,  all of whom
were  incumbent  directors  and who were  re-elected.  In  addition to voting on
election  of six  director  nominees,  the  shareholders  voted on a proposal to
increase authorized shares of common stock of the Company from 20,000,000 shares
to  50,000,000  shares;  a proposal to adopt the amended and restated 2001 stock
incentive plan; and a proposal to adopt the amended and restated  certificate of
formation.  All of these  proposals  were  approved  by  shareholders.  No other
matters  were  presented  for a vote at the annual  meeting.  Of the  13,790,312
shares of common stock present in person or by proxy, the number of shares voted
for or against in  connection  with the election of each  director and the three

Section 5. Quorum of Shareholders. The holders of at least a majority of the
shares issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at all meetings of the
shareholders for the transaction of business except as otherwise provided by
law, the Amended and Restated Certificate of Formation or these By-Laws. If a
quorum is present at any shareholders' meeting, the vote of the holders of a
majority of the shares entitled to vote, present in person or represented by
proxy, shall decide any question brought before such meeting, unless the
question is one upon which a different vote is required by law or by the Amended
and Restated Certificate of Formation.

Section 6. Adjournments of Annual and Special Meetings of the Shareholders. If,
however, a quorum shall not be present or represented at any meeting of the
shareholders, the shareholders entitled to vote thereat, present in person or
represented by proxy, may adjourn the meeting from time to time, without notice
(other than announcement at the meeting), until a quorum shall be present or
represented. When a quorum is assembled for such an adjourned meeting, any
business may be transacted which might have been transacted at the meeting as
originally noticed. If the adjournment is for more than thirty (30) days, or if
after the adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given to each shareholder of record
entitled to vote at the meeting.

Section 7. Meetings of the Shareholders. The President of the Corporation, or in
the event of his absence or omission or refusal to so act, a Vice President of
the Corporation, shall call each meeting of the shareholders to order and shall
act as Chairman of such meeting. If for any reason whatever, neither the
President nor a Vice President of the Corporation acts or will act as the

                                       3



Chairman of the meeting of the shareholders, then the shareholders present, in
person or by proxy, and entitled to vote thereat may by majority vote appoint a
Chairman who shall act as Chairman of the meeting.
         The Secretary of the Corporation, or in the event of his absence,
omission or refusal to act, an Assistant Secretary, shall act as Secretary of
each meeting of the shareholders. If for any reason whatever, neither the
Secretary nor an Assistant Secretary acts or will act as Secretary of the
meeting of shareholders, then the Chairman of the meeting or, if he fails to do
so, the shareholders present, either in person or by proxy, and entitled to vote
thereat may by majority vote appoint any person to act as Secretary of the
meeting.

Section 8. Attendance and Proxies. Each outstanding share of the Corporation's
capital stock, regardless of class or series, will be entitled to one vote on
each matter submitted to a vote at a meeting of shareholders, except to the
extent that the voting rights of the shares of any class or series are limited
or denied by the Amended and Restated Certificate of Formation. At any meeting
of the shareholders, every shareholder having the right to vote will be entitled
to vote in person or by proxy executed in writing by the shareholder and bearing
a date not more than eleven months before the meeting, unless the proxy provides
for a longer period. A telegram, telex, cablegram, or similar transmission by
the shareholder or a photographic, photostatic, facsimile, or similar
reproduction of a writing executed by the shareholder will be treated as any
execution in writing. Any electronic transmission must contain or be accompanied
by information for which it can be determined that the transmission was
authorized by the shareholder. Each proxy will be revocable unless expressly
provided that it is irrevocable and if, and only as long as, it is coupled with
an interest sufficient in law to support an irrevocable power. Each proxy will

                                       4



be filed with the secretary of the Corporation before or at the time of the
meeting. Voting for directors will be in accordance with Article III of these
By-Laws. Voting on any question or in any election may be by voice vote or show
of hands unless the presiding officer orders or any shareholder demands that
voting be by written ballot.

Section 9. Voting of Shares. At each meeting of the shareholders, each
outstanding share, regardless of class, standing in the shareholder's name on
the stock and transfer books shall be entitled to one (1) vote, subject however,
to the provisions of Section 6 of Article VIII of these By-Laws, and excepting
only as may be otherwise provided or required by law, on each matter submitted
to a vote at such meeting, unless the voting rights of the shares of any class
or classes are limited or denied by the Amended and Restated Certificate of
Formation as permitted by law. Treasury shares, shares of its own stock owned by
another corporation, the majority of the voting stock of which is owned or
controlled by it, and shares of its own stock held by a corporation in a
fiduciary capacity shall not be voted, directly or indirectly, at any meeting,
and shall not be counted in determining the total number of outstanding shares
at any given time.
         At any election for directors of the Corporation, each and every
shareholder entitled to vote may cumulate his votes and give one candidate a
number of votes equal to the number of directors to be elected, multiplied by
the number of votes to which his shares are entitled; or each shareholder may
distribute his votes on the same principle among as many candidates for
directors as the shareholder thinks fit.
         Any shareholder who intends to cumulate his votes must give written
notice of this intention to the Secretary of the Corporation on or before the
day preceding the election at which the shareholder intends to cumulate his
votes.
         The candidates for directors receiving the highest number of votes, up
to the number of directors to be elected, are elected.

                                       5



Section 10. Voting of Shares Owned by Another Corporation. Shares of stock of
this Corporation standing in the names of another corporation, domestic or
foreign, on the books and records of this Corporation and having voting rights
may be voted by such officer, agent or proxy as the By-Laws of such other
corporation may authorize, or, in the absence of such authorization, as the
Board of Directors of such other corporation may determine, subject to such
provisions of the Texas Business Organizations Code as may be applicable in
any instance.

Section 11. Shares Held by Fiduciaries, Receivers, Pledgees. Shares held by an
administrator, executor, guardian, or conservator, may be voted by him so long
as such shares forming a part of an estate are in the possession and forming a
part of the estate being served by him, either in person or by proxy, without a
transfer of such shares into his name. Shares standing in the name of a trustee
may be voted by him, either in person or by proxy, but no trustee shall be
entitled to vote shares held by him unless such share shall have been
transferred into his name as trustee. Shares standing in the name of a receiver
on the books and records of this Corporation may be voted by such receiver, and
shares held by or under the control of a receiver may be voted by such receiver
without such shares being transferred into his name if appropriate authority so
to do be contained in an appropriate order of the court by which such receiver
was appointed. A shareholder whose shares are pledged shall be entitled to vote
such shares until such shares have been transferred on the books and records of
the Corporation into the name of the pledgee, unless in the transfer by the
pledgor on the books and records of the Corporation, he shall have expressly
empowered the pledgee to vote such shares, and thereafter the pledgee shall be
entitled to vote the share so transferred.

Section 12. Decisions at Meetings of Shareholders. At all meetings of the
shareholders all questions, business and matters, except those the manner of
deciding which is otherwise expressly governed by the Texas Business

                                       6



Organizations Code or by the Amended and Restated Certificate of Formation or by
these By-Laws, shall be decided by the vote of the holders of a majority of the
votes of the shareholders of the Corporation present in person or by proxy, and
entitled to vote, a quorum being present. All voting shall be viva voce, except
that upon the determination of the officer or person presiding at the meeting or
upon the demand of any qualified voter or his proxy, voting on any further
question, matter or business at such meeting shall be by ballot. In the event
any business, question or matter is so voted upon by ballot, then each ballot
shall be signed by the shareholder voting, or by his proxy and shall state the
number of shares so voted.

Section 13. List of Shareholders. The officer or agent who has charge of the
stock transfer books of the Corporation shall prepare and make, at least eleven
(11) days before each meeting of shareholders, a complete list of the
shareholders entitled to vote at such meeting or any adjournment thereof,
arranged in alphabetical order, showing the address and the type and number of
shares held by each shareholder and number of votes to which each shareholder is
entitled (if different from the number of shares). Such list shall be kept on
file at the registered office or the principal place of business of the
Corporation and shall be open to inspection by any shareholder at any time
during usual business hours, for a period of at least ten (10) days prior to
such meeting.
         Alternatively, the list of the shareholders may be kept on a reasonably
accessible electronic network, if the information required to gain access to the
list is provided with the notice of the meeting. The Corporation is not required
to include any electronic contact information of any shareholder on the list. If
the Corporation elects to make the list available on an electronic network, the
Corporation shall take reasonable steps to ensure that the information is

                                       7


available only to shareholders of the Corporation. Such list shall also be
produced and kept open at the time and place of such meeting during the whole
time thereof, and may be inspected by any shareholder who is present. If the
meeting is held by means of remote communication, the list must be open to the
examination of any shareholder for the duration of the meeting on a reasonably
accessible electronic network, and the information required to access the list
must be provided to shareholders with the notice of the meeting. The original
stock transfer books shall be prima facie evidence as to who are the
shareholders entitled to examine such list or transfer book or to vote at any
such meeting of shareholders.

Section 14.       Action Without Meeting.

     a. Any action  required by law to be taken at any annual or special meeting
of the shareholders,  may be taken without a meeting,  without prior notice, and
without a vote, if a consent or consents in writing, setting forth the action so
taken,  shall  have been  signed  by the  holder or  holders  of all the  shares
entitled to vote with respect to the action that is subject of the consent.

     b.  Every  written  consent  of the  shareholders  shall  bear  the date of
signature of each shareholder who signs the consent. No written consent shall be
effective to take the action that is the subject of the consent  unless,  within
sixty (60) days after the date of the earliest  dated  consent  delivered to the
Corporation  as provided  below,  a consent or consents  signed by the holder or
holders of shares having not less than the minimum number of votes that would be
necessary to take the action that is the subject of the consent are delivered to
the  Corporation by delivery to its registered  office,  its principal  place of
business,  or an officer or agent of the Corporation having custody of the books
in which proceedings of meetings of the shareholders are recorded. Such delivery

                                       8



shall  be made by  hand or by  certified  or  registered  mail,  return  receipt
requested,  and in the case of delivery to the Corporation's  principal place of
business, shall be addressed to the President of the Corporation.

     c. A telegram,  telex,  cablegram,  or other  electronic  transmission by a
shareholder  consenting  to an action to be taken is  considered  to be written,
signed,  and dated for the  purposes of this  Section if the  transmission  sets
forth or is delivered with  information from which the Corporation can determine
that the  transmission  was transmitted by the shareholder and the date on which
the shareholder  transmitted the  transmission.  The date of transmission is the
date on  which  the  consent  was  signed.  Consent  given by  telegram,  telex,
cablegram,  or other  electronic  transmission  may not be considered  delivered
until the consent is reproduced in paper form and the paper form is delivered to
the  Corporation  at its  registered  office in Texas or its principal  place of
business,  or to an officer or agent of the  Corporation  having  custody of the
book in which proceedings of shareholder meetings are recorded.  Notwithstanding
Subsection (b) of this Section, consent given by telegram,  telex, cablegram, or
other  electronic  transmission  may be  delivered  to the  principal  place  of
business of the Corporation or to an officer or agent of the Corporation  having
custody of the book in which proceedings of shareholder meetings are recorded to
the extent and in the manner provided by resolution of the Board of Directors of
the Corporation. Any photographic, photostatic, facsimile, or similarly reliable
reproduction  of a consent in writing signed by a shareholder may be substituted
or used instead of the  original  writing for any purpose for which the original
writing could be used, if the  reproduction  is a complete  reproduction  of the
entire original writing.

                                       9



     d.  Prompt  notice of the  taking of any action by  shareholders  without a
meeting  by less  than  unanimous  written  consent  shall  be  given  to  those
shareholders who did not consent in writing to the action.

Section 15. Telephone or Remote Communications. Shareholders may participate in
and hold a shareholders' meeting by means of conference telephone or other means
of remote communication equipment by means of which all persons participating in
the meeting can hear each other. Participation in such a meeting shall
constitute presence in person at such meeting, except where a person
participates in the meeting for the express purpose of objecting to the
transaction of any business on the ground that the meeting is not lawfully
called or convened, if (i) the Corporation implements reasonable measures to
verify that each person considered present and permitted to vote at the meeting
by means of remote communication is a shareholder; (ii) the Corporation
implements reasonable measures to provide the shareholders at the meeting by
means of remote communication a reasonable opportunity to participate in the
meeting and to vote on matters submitted to the shareholders, including an
opportunity to read or hear the proceedings of a meeting substantially
concurrently with the proceedings; and (iii) the Corporation maintains a record
of any shareholder vote or other action taken at the meeting by means of remote
communication.

Section 16. Record Date. The Board of Directors shall have the power to close
the stock transfer books of the Corporation or, in lieu thereof, to fix a record
date for the determination of the shareholders entitled to notice of or to vote
at any meeting of the shareholders and at any adjournment or adjournments
thereof and to fix a record date for any other purpose or purposes as provided
in Section 6 of Article VIII of these By-Laws.

of Directors may be filled by the affirmative vote of a majority of the

by any three of the Directors for the time being in office, and at the place,

determination may be conclusively evidenced in a call, waiver of notice or by
an electronic transmission signed or delivered by such officer or such three
directors.

Section 13. Notice. The Secretary or an Assistant Secretary shall, but in the
event of the absence of the Secretary or an Assistant Secretary or the failure,
inability, refusal or omission on the part of the Secretary or an Assistant
Secretary so to do, any other officer of the Corporation may, give notice of
each special meeting, and of the place, day and hour of the particular meeting,
in person or by mail, or by telephone, telegraph, electronic transmission or
other means of communication, at least three (3) days before the meeting of each
director. The attendance of a director at any meeting shall constitute a waiver
of notice of such meeting, except where a director attends a meeting for the
express purpose of objecting to the transaction of any business on the ground
that the meeting is not lawfully called or convened.

Section 14. Business to be Transacted. Neither the business to be transacted at,
nor the purpose or purposes of, any regular or special meeting of the Board of
Directors need be specified in the notice or any waiver or waivers of notice of
such meeting. Any and all business of any nature or character whatsoever may be


                                       13

other meeting, regular or special, of the Board of Directors. At any meeting at

or any first meeting, of the Board of Directors there be less than a quorum
present, a majority of those present, or if only one director be present, then
such director, may adjourn the meeting from time to time without notice, other
than by announcement at the meeting, until a quorum shall be present at the

Directors, or if only one director be present, then such director, may adjourn
any meeting of the Board from time to time without notice, other than by
announcement at such meeting of the time and place at which the meeting will
reconvene, until the transaction of any and all business submitted or proposed
to be submitted to such meeting or any adjournment or adjournments thereof shall
have been completed. The act of a majority of the directors present at any
meeting of the Board of Directors at which a quorum is in attendance shall
constitute the act of the Board of Directors unless the act of a greater number
is required by the Amended and Restated Certificate of Formation or by these
By-Laws.

Section 16. Action Without Meeting. Unless otherwise restricted by law or the
Amended and Restated Certificate of Formation, any action required or permitted

                                       14


thereof, as the case may be. A telegram, telex, cablegram or other electronic
transmission by a director consenting to an action to be taken and transmitted
by a director is considered written, signed, and dated for the purposes of this
Article III if the transmission sets forth or is delivered with information from
which the Corporation can determine that the transmission was transmitted by the
director and the date on which the director transmitted the transmission. Such
consent shall have the same force and effect as a unanimous vote at a meeting of
the Board of Directors or the committee, as the case may be, duly called and
held.

Section 17. Compensation. Directors, as such, shall not be entitled to
receive any fixed sums or stated salaries for their services, but, by resolution
of the Board, a fixed sum and expenses of attendance, if any, may be provided
and allowed by the Board of Directors for attendance at meetings of the Board,
whether regular or special, or first meetings; provided that nothing herein
contained shall, or shall be construed so as to, preclude any director from
serving the Corporation in any other capacity or receiving compensation
therefor. Members of special or standing committees may be allowed a fixed sum
and expenses of attendance, if any, at committee meetings.

business shall be transacted in such order as from time to time the Board of
Directors may determine. At all meetings of the Board of Directors a Chairman
shall be chosen by the Board from among the directors present and such Chairman
so chosen shall preside at the meeting.
         The Secretary of the Corporation, or in his absence, an Assistant
Secretary, shall act as Secretary of the meetings of the Board of Directors, but
in the absence of the Secretary and an Assistant Secretary, or if for any reason
neither acts as Secretary thereof, the presiding officer shall appoint any

                                       15



person of his choice to act, and such person shall act as Secretary at the
meeting.

Section 19. Presumption of Assent. A director of the Corporation who is
present at a meeting of the Board of Directors at which action on any corporate
matter is taken shall be presumed to have assented to the action unless his
dissent shall be entered in the minutes of the meeting or unless he shall file
his written dissent to such action with the person acting as the Secretary of
the meeting before the adjournment thereof or shall forward such dissent by
registered mail to the Secretary of the Corporation immediately after the
adjournment of the meeting. Such right to dissent shall not apply to a director

activities of this Corporation, without breach of duty to this Corporation or to
its shareholders and without accountability or liability to this Corporation or
to its shareholders in any event or under any circumstances or conditions.

represent any other corporation or corporations, entity or entities, and any
person or persons, in any capacity or capacities, and be or become a director or
officer, or both, of any other corporation or corporations, entity or entities,

Corporation and one or more of its directors or officers or between the
Corporation and any other entity in which one or more of the Corporation's
directors or officers is a managerial official or has a financial interest will
be void or voidable (a) for this reason; (b) because the director or officer is
present at or participates in the meeting of the Board of Directors or committee
that authorizes the contract or transaction; or (c) because his vote authorizes
the contract or transaction if (i) the material facts of his relationship or
interest and of the contract or transaction are disclosed or are known to the
board of directors or the committee, and the Board of Directors or committee in
good faith authorizes the contract or transaction by the affirmative vote of a
majority of the disinterested directors or committee members, even though the
disinterested directors or committee members are less than a quorum; (ii) the
material facts of his relationship or interest and of the contract or
transaction are disclosed or are known to the shareholders entitled to vote
thereon, and the contract or transaction is specifically approved in good faith
by vote of the shareholders; or (iii) the contract or transaction is fair as to
the Corporation as of the time it is authorized, approved, or ratified by the
Board of Directors, a committee thereof, or the shareholders. Common or
interested directors may be counted in determining the presence of a quorum at a
meeting of the Board of Directors or of a committee that authorizes the contract
or transaction.

in Section 3 of this Article IV and shall inure to the benefit of the heirs,
executors and administrators of such a person.

Section 5. Powers Not Exclusive. The indemnification provided by this Article IV
shall not be deemed exclusive of any other power to indemnify or right to
indemnification which the Corporation or any person in any capacity referred to
in Section 3 of this Article IV may have or acquire under the law including,
without limitation, the Texas Business Organizations Code, or any amendment
thereto or substitute therefor.

Section 1. Committees of Directors. The Board of Directors, by resolution
adopted by a majority of the full Board of Directors, may designate from among

all of the authority of the Board of Directors, except that no such committee
shall have the authority of the Board of Directors when the action of the Board
of Directors is required or the authority of the committee is limited by

Board of Directors. No notice of any meeting of any committee shall be required,
and a majority of the members of the committee shall constitute a quorum for the
transaction of business. The designation of such a committee and the delegation

ARTICLE VIII

                                  CAPITAL STOCK

Section 1. Stock Certificates. The certificates for shares of the capital stock
of the Corporation shall be in such form as shall be approved by the Board of
Directors. They shall be consecutively numbered and shall be entered in the
books of the Corporation as they are issued and shall exhibit the holder's name
and the number of shares. Every holder of stock in the Corporation shall be
entitled to have a certificate signed by, or in the name of the Corporation by
the President, or a Vice President, and the Secretary or an Assistant Secretary
of the Corporation, certifying the number of shares owned by him in the
Corporation, with the seal of the Corporation or a facsimile thereof impressed
or printed thereon. Where any such certificate is countersigned by a transfer

                                       24

agent, or registered by a registrar, either of which is other than the
Corporation itself or an employee of the Corporation, the signatures of the
President or Vice President and the Secretary or Assistant Secretary upon a
certificate may be facsimiles, engraved or printed. In case any officer or
officers who shall have signed, or whose facsimile signature or signatures shall
have been used or placed on any such certificate or certificates shall have
ceased to be such officer or officers of the Corporation, whether because of
death, resignation or otherwise, before such certificate is, or such
certificates are, issued, such certificate or certificates may nevertheless be
issued and delivered by the Corporation as though the person or persons who
signed such certificate or certificates or whose facsimile signature or
signatures have been used thereon was or were such officer or officers at the
time of issuance thereof, and with the same effect as if he or they were such
officer or officers at the date of issuance thereof.

Section 2. Transfers. Stock of the Corporation shall be transferable in the
manner prescribed by the laws of the State of Texas and in these By-Laws.
Transfers of stock shall be made on the books of the corporation only by the
person named in the certificate, or by his attorney or attorneys-in-fact,
legal representative or legal representatives, duly and lawfully authorized in
writing, and upon the surrender of the certificate therefor, which shall be
cancelled before the new certificate, certificates in the aggregate, for a like
number of shares shall be issued.
         The Board of Directors may appoint a transfer agent or registrar for
each class of stock, and may require all stock certificates to bear the
signature of such transfer agent and of such registrar or either of them.

Section 3. Registered Holders. The Corporation shall be entitled to treat the
person in whose name any share of stock or any warrant, right or option is
registered as the owner thereof for all purposes and shall not be bound to
recognize any equitable or other claim to, or interest in, such share, warrant,

                                       25


right or option on the part of any other person, whether or not the Corporation
shall have notice thereof, save as may be expressly provided otherwise by the
laws of the State of Texas.

Section 4. New Certificates. The Corporation may, in its sole discretion,
issue a new certificate for shares of its stock in the place of any certificate
theretofore issued by it, alleged to have been lost or destroyed, and the
Board of Directors may, in its discretion, require the owner of the lost or
destroyed certificate, or his legal representative or representatives, to give
the Corporation such statement under oath or other evidence of such loss or
destruction as the Board may desire, and a bond in form, amount and with such
surety or sureties as the Board of Directors may prescribe or determine, and
sufficient, in the sole judgment of the Board, to indemnify and protect the
Corporation against any and all claims, liabilities, costs and expenses that
may be made or asserted against it or which it may suffer or incur or pay, on
account of the alleged loss of any such certificate or the issuance of such
new certificate. A new certificate may be issued without requiring any bond
when, in the sole discretion of the Board, it is proper so to do.

Section 5. Dividends. The Board of Directors may declare dividends as and when
the Board deems expedient and as may be permitted by law and under the
provisions of the Texas Business Organizations Code. Before declaring any
dividend there may be reserved out of the earned surplus such sum or sums as the
Board of Directors, from time to time in the absolute discretion of the
directors, deems proper for working capital or as a reserve fund to meet
contingencies or for equalizing dividends, or for such other purposes as the
Board may deem conducive to the interests of the Corporation, and the Board may
abolish any such reserve in the manner in which it was created.

                                       26

Section 6. Record Dates and Closing of Transfer Books. For the purpose of
determining shareholders entitled to notice of or to vote at any meeting of
shareholders, or any adjournment thereof, or entitled to receive payment of any
dividend, or in order to make a determination of shareholders for any other
proper purpose, the Board of Directors of the Corporation may provide that the
stock transfer books shall be closed for a stated period but not to exceed, in
any case, sixty (60) days. If the stock transfer books shall be closed for the
purpose of determining shareholders entitled to notice of or to vote at a
meeting of shareholders, such books shall be closed for at least ten (10) days
immediately preceding such meeting. In lieu of closing the stock transfer books
the Board of Directors may fix in advance a date as the record date for any such
determination of shareholders, such date in any case to be not more than sixty
(60) days and, in case of a meeting of shareholders, not less than ten (10) days
prior to the date on which the particular action requiring such determination of
shareholders is to be taken. If the stock transfer books are not closed and no
record date is fixed for the determination of shareholders entitled to notice of
or to vote at a meeting of shareholders, or shareholders entitled to receive
payment of a dividend, the date on which the notice of the meeting is mailed or
the date on which the resolution of the Board of Directors' declaring such
dividend is adopted, as the case may be, shall be the record date for such
determination of shareholders.


Section 7. Regulations. The Board of Directors shall have power and authority to
make all such rules and regulations as they may deem expedient concerning the
issue, transfer and registration or the replacement for certificates of shares
of the capital stock of the Corporation.

                                       27

                                   ARTICLE IX

                            MISCELLANEOUS PROVISIONS

Section 1. Fiscal Year. The fiscal year of the Corporation shall be such as the
Board of Directors shall, by resolution, provide or establish or such as the
President shall determine subject to approval of the Board.

Section 2. Seal. The seal of the Corporation shall be in such form as the
Board of Directors shall prescribe, and may be used by causing it or a
facsimile thereof to be impressed, or affixed, or printed, or reproduced or in
any other manner.

Section 3. Notice.
Any notice to directors, shareholders and committee members shall be in writing
and may be delivered personally, or by mail to the directors, shareholders or
committee members at their respective addresses appearing on the books and share
transfer records of the Corporation. Notice to shareholders shall be deemed to
be given at the time when the same shall be so delivered or mailed. Notice to
directors and committee members may also be given by nationally recognized
overnight delivery or courier service, and shall be deemed given when such
notice shall be received by the proper recipient or, if earlier, (i) in the case
of an overnight delivery or courier service, one (1) day after such notice is
sent by such overnight delivery or courier service; (ii) in the case of
telegraph, when deposited at a telegraph office for transmission and all
appropriate fees therefore have been paid; and (iii) in the case of mailing by
U.S. mail, three (3) days after such notice is mailed as described above. On
consent of a shareholder, director or committee member, notice from the
Corporation may be given to the shareholder, director or committee member by
electronic transmission. The shareholder, director or committee member may
specify the form of electronic transmission to be used to communicate notice.
The shareholder, director or committee member may revoke this consent by written
notice to the Corporation. The consent is deemed to be revoked if the

                                       28

Corporation is unable to deliver by electronic transmission two consecutive
notices, and the person responsible for delivering notice on behalf of the
Corporation knows that delivery of these two electronic transmissions was
unsuccessful. The inadvertent failure to treat the unsuccessful transmissions as
a revocation of consent does not invalidate a meeting or other action. Notice by
electronic transmission is deemed given when the notice is (i) transmitted to a
facsimile number provided by the shareholder, director or committee member for
the purpose of receiving notice; (ii) transmitted to an electronic mail address
provided by the shareholder, director or committee member for the purpose of
receiving notice; (iii) posted on an electronic network and a message is sent to
the shareholder, director or committee member at the address provided by the
shareholder, director or committee member for the purpose of alerting the
shareholder, director or committee member of a posting; or (iv) communicated to
the shareholder, director or committee member by any other form of electronic
transmission consented to by the shareholder, director or committee member.

Section 4. Waiver of Notice. Whenever any notice is required to be given by law,
the Amended and Restated Certificate of Formation or these By-Laws, a waiver
thereof in writing signed by the person or persons entitled to such notice, or a
waiver by electronic transmission by the person entitled to notice, whether
before or after the time stated therein, shall be deemed equivalent to the
giving of such notice. The business to be transacted at a regular or special
meeting of the shareholders, directors, or members of a committee of directors
or the purpose of a meeting is not required to be specified in a written waiver
of notice or a waiver by electronic transmission unless required by the Amended
and Restated Certificate of Formation. Attendance of a director at any meeting
of the Board of Directors or any committee thereof, and attendance of a
shareholder at any meeting of the shareholders shall constitute a waiver of
notice of such meeting, except where a director or shareholder attends for the
express purpose of objecting to the transaction of any business on the ground
that the meeting is not lawfully called or convened.

Section 5. Resignations. Any director or officer may resign at any time.
Each such resignation may be made in writing or by electronic transmission and
shall take effect at the time specified therein, or, if no time be specified,
at the time of its receipt by either the Board of Directors or the President or
the Secretary. The acceptance of a resignation shall not be necessary to make
it effective, unless expressly so provided in the resignation.

Section 6. Telephone and Similar Meetings. Shareholders, directors, and
committee members may participate in and hold meetings by means of conference
telephone or other similar means of remote communication equipment such that all
participants in the meeting can communicate with each other. Participation in
such a meeting will constitute presence in person at the meeting, except when a
person participates in the meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business on the ground that
the meeting had not been lawfully called or convened.

Section 7. Securities of Other Corporations. The President or any Vice President
of the Corporation shall have power and authority to transfer, endorse for
transfer, vote, consent or take any other action with respect to any securities
of another issuer which may be held or owned by the Corporation and to make,
execute and deliver any waiver, proxy or consent with respect to any such
securities.

Section 8. Depositories. Funds of the Corporation not otherwise employed shall
be deposited from time to time in such banks or other depositories as either the
Board of Directors or the President or the Treasurer may select or approve.

                                       30

Section 9. Signing of Checks, Notes, etc. In addition to and cumulative of, but
in nowise limiting or restricting, any other provision or provisions of these
By-Laws which confer any authority relative thereto, all checks, drafts and
other orders for the payment of money or moneys out of funds of the Corporation
and all notes and other evidences of indebtedness of the Corporation shall be
signed on behalf of the Corporation, in such manner, and by such officer or
officers, person or persons, as shall from time to time be determined or
designated by or pursuant to resolution or resolutions of the Board of
Directors; provided, however, that if, when, after and as authorized or provided
for by resolution or resolutions of the Board of Directors the signature or
signatures of any such officer or officers, person or persons, may be facsimile
or facsimiles, engraved or printed, and shall have the same force and effect and
bind the Corporation as though such officer or officers, person or persons, had
signed the same personally, and, in event of the death, disability, removal or
resignation of any such officer or officers, person or persons, if the Board of
Directors shall so determine or provide, as though and with the same effect as
if such death, disability, removal or resignation had not occurred.

Section 10. Persons. Wherever used or appearing in these By-Laws, pronouns of
the masculine gender shall include the persons of the female sex as well as the
neuter gender and the singular shall include the plural wherever appropriate.

Section 11. Laws and Statutes. Wherever used or appearing in these By-Laws, the
words "law" or "laws" or "statute" or "statutes", respectively, shall mean and
refer to laws and statutes, or a law or a statute, of the State of Texas, to the
extent only that such is or are expressly applicable, except where otherwise
expressly stated or the context requires that such words not be so limited.

                                       31

Section 12. Headings. The headings of the Articles and Sections of these By-Laws
are inserted for convenience of reference only and shall not be deemed to be a
part thereof or used in the construction or interpretation thereof.

                                   ARTICLE X

                                   AMENDMENTS

Section 1. Amendment of By-Laws. The By-Laws of the Corporation may be altered,
amended or repealed or new By-Laws may be adopted by either the unanimous action
of the Board of Directors or the shareholders. Such equal power to alter, amend,
or repeal the By-Laws or adopt new By-Laws was delegated to the Board of
Directors by the adoption of this By-Law by the shareholders.

                                 CERTIFICATIONS

I, John R. Irwin, certify that:

1.                I have reviewed this quarterly report on Form 10-Q of Atwood
                  Oceanics, Inc.;

2.                Based on my knowledge, this report does not contain any untrue
                  statement of a material fact or omit to state a material fact
                  necessary to make the statements made, in light of the
                  circumstances under which such statements were made, not
                  misleading with respect to the period covered by this report;

3.                Based on my knowledge, the financial statements, and other
                  financial information included in this report, fairly present

                  operations and cash flows of the registrant as of, and for,
                  the periods presented in this report;

4.                The registrant's other certifying officer(s) and I are
                  responsible for establishing and maintaining disclosure
                  controls and procedures (as defined in Exchange Act Rules
                  13a-15(e) and 15d-15(e)) and internal control over financial

                  15d-15(f)) for the registrant and have:

                  (a) Designed such disclosure controls and procedures, or
                  caused such disclosure controls and procedures to be designed
                  under our supervision, to ensure that material information
                  relating to the registrant, including its consolidated
                  subsidiaries, is made known to us by others within those
                  entities, particularly during the period in which this report
                  is being prepared;

                  (b) Designed such internal control over financial reporting to

                  in accordance with generally accepted accounting principles;
                  and

                  controls and procedures and presented in this report our
                  conclusions about the effectiveness of the disclosure controls
                  and procedures, as of the end of the period covered by this
                  report based on such evaluation; and

                  (d) Disclosed in this report any change in the registrant's
                  internal control over financial reporting that occurred during
                  the registrant's most recent fiscal quarter (the registrant's
                  fourth fiscal quarter in the case of an annual report) that
                  has materially affected, or is reasonably likely to materially
                  affect, the registrant's internal control over financial
                  reporting; and
