                       1999 ANNUAL REPORT TO SHAREHOLDERS

                                   THE COMPANY






     Atwood Oceanics,  Inc. is engaged in the business of international offshore
drilling of exploratory and developmental oil and gas wells and related support,
management and consulting services.  Presently,  the Company owns and operates a
modern fleet of seven mobile offshore rigs and one modular platform rig, as well
as manages the  operations  of two  operator-owned  platform  rigs in  Northwest
Australia.  The Company  also owns a fifty  percent  interest in a platform  rig
located in Australia.  The Company supports its operations from  headquarters in
Houston and affiliated offices in Australia,  Malaysia, Indonesia,  Philippines,
United Kingdom, Egypt, India and Israel.




TO OUR SHAREHOLDERS AND EMPLOYEES:

     Operating  results  for fiscal 1999  represent  the  Company's second best
financial performance in its thirty-year history,  despite 1999 not being a good
year,  in general,  for the  offshore  drilling  market.  The  Company  remained
financially strong and continued to enhance  shareholders'  equity during fiscal
year 1999 with revenues of $150.0 million,  operating cash flows (before changes
in working  capital and other assets and  liabilities)  of $55.7 million and net
income of $27.7 million.

     Even  though  market  conditions  resulted in the  Company  having  certain
periods of idle time during fiscal 1999 on the ATWOOD SOUTHERN CROSS,  RICHMOND,
RIG-19  and  RIG-200,  term  contracts  in place for the ATWOOD  HUNTER,  ATWOOD
FALCON,  VICKSBURG and SEAHAWK,  as well as contributions from the ATWOOD EAGLE,
assisted in maintaining the Company's  strong  financial  performance.  With the
cyclical nature of the drilling  business,  the recent  downturn  reinforces our
belief that the strategy of  maintaining  a mix of  long-term  contracts at good
margins, coupled with short-term contracts,  provides downside protection during
market  declines  with upside  potential  for enhanced  earnings in an improving
market environment.  With this strategy, the Company has been well-positioned to
capitalize  on future  market  improvements  and will  continue  to explore  all
possible growth  opportunities  and current fleet  enhancements.

     Upgrade of the  semisubmersible  tender-assist unit SEAHAWK for a four-year
contract  extension is progressing  satisfactorily.  A new derrick equipment set
for the SEAHAWK is being loaded on the  tender-assist  unit for  mobilization to
the unit's first drill location. It is anticipated that  commencement of dayrate
operations  under the contract  extension  should occur during our second fiscal
2000 quarter.  Dayrates in the contract extension have upside potential based on
higher  average  oil  prices.

     The ATWOOD FALCON and ATWOOD HUNTER have term  commitments that should keep
both units employed into fiscal years 2001 and 2002,  respectively.  The jack-up
VICKSBURG  has a  conditional  letter of intent  which could also keep that unit
employed  through  fiscal year 2000.  The SEAHAWK  should  remain  employed into
fiscal  year  2004.  The  submersible  RICHMOND  has  been  back at  work  since
September  1999  utilizing  its  unique  operating   characteristics,   and  is
benefiting from increasing  dayrates and an improving  outlook for shallow-water
units  in  the  Gulf  of  Mexico.  The  ATWOOD  EAGLE  achieved  virtually  100%
utilization during fiscal year 1999, though at significantly reduced dayrates in
the fourth quarter  following market  deterioration,  and should remain employed
until late in the first  quarter of fiscal year 2000.  The ATWOOD  EAGLE is then
scheduled  to  undergo  an upgrade  in its  variable  deck load and water  depth
capability utilizing a wire insert system, which could take up to ninety days to
complete.  The ATWOOD SOUTHERN CROSS is being bid for  opportunities  commencing
next year and has the potential for providing the Company with additional upside
in an improving market  environment.

     The successful completion during 1997 and 1998 of four major rig upgrades
ATWOOD FALCON, ATWOOD HUNTER, VICKSBURG and ATWOOD SOUTHERN CROSS have already
proven beneficial to the Company's  financial results. We believe these upgrades
will also be beneficial in terms of future opportunities and financial upside in
a  strengthening  market.

     We  remain   committed   to  a  strategy   of   international   operations,
highly-skilled  personnel,  premium equipment and financial strength. The recent
improvement  in oil and gas prices is  encouraging  and,  if  sustained,  should
ultimately lead to an increase in operators' drilling budgets.  Accordingly,  we
are  optimistic   about  the   longer-term   outlook  and  gradually   improving
fundamentals.  Our goal of achieving  safe  operations  receives our  day-to-day
attention.  As always,  we want to thank our  employees  for their  efforts  and
contributions, and our shareholders for their continuing support.


                                                              John R. Irwin

OUTLOOK

     At the  beginning  of fiscal  1999,  the price for oil was  around  $12 per
barrel,  with worldwide fleet utilization for mobile offshore rigs on a decline.
Even though the oil price has recovered to over $20 per barrel,  worldwide fleet
utilization  for mobile offshore rigs has remained around 75 percent for most of
1999.  Due to this  weakness in the  worldwide  offshore  drilling  market,  the
Company has been unable to identify an ongoing  contract for the ATWOOD SOUTHERN
CROSS since it completed its last contract at the end of September 1998, and has
incurred  certain  periods of idle time during fiscal year 1999 on the RICHMOND,
RIG-19 and RIG-200.

     Despite a down trend in the offshore  drilling  market and certain idle rig
time,  term contracts in place for the ATWOOD HUNTER,  ATWOOD FALCON,  VICKSBURG
and  SEAHAWK,  as well as a good  year for the  ATWOOD  EAGLE,  resulted  in the
Company  generating in 1999 the second highest level of revenue,  operating cash
flows and net income in its history. There are some encouraging indications that
the offshore drilling market  environment  could improve in 2000.  Historically,
worldwide fleet utilization of mobile offshore rigs needs to approach 90 percent
before significant improvement in dayrate levels will occur. Even without market
improvement,  the  Company's  contract  backlog  should  provide a high level of
revenues and cash flows in fiscal  2000.  The Company  remains  confident in the
long-term future of the worldwide offshore drilling market.


RESULTS OF OPERATIONS

Fiscal Year 1999 Versus  Fiscal Year 1998

     Despite the Company's  active rig utilization  decreasing from 100% in 1998
to 77% in 1999,  contract  revenues only declined  approximately  1 percent.  An
analysis  of  contract  revenues  by rig for  fiscal  year  1999  and 1998 is as
follows:

     The  ATWOOD  FALCON  was in a  shipyard  from  May  1998 to  November  1998
undergoing a water-depth  upgrade.  The VICKSBURG entered a shipyard in December
1997 for  refurbishment and upgrade which was not completed until November 1998.
The ATWOOD FALCON and VICKSBURG have worked continuously since the completion of
their  upgrades.  The  ATWOOD  EAGLE  was  relocated  from  West  Africa  to the
Mediterranean  Sea area in March 1998.  The  increase in revenues for the ATWOOD
EAGLE is due to enhanced  dayrate  for a portion of the year from term  contract
commitments.  The increase in revenues from the GOODWYN 'A' and NORTH RANKIN 'A'
rigs is due to the Company  providing additional  labor and  assistance  to the
rigs'  Australian  owner in upgrading the rigs during  fiscal 1999.  The Company
expects  to be  involved  in the  operation  of both rigs at least into the year
2001; however,  the Company expects revenues from these rigs to decline in 2000.
RIG-200 and RIG-19 are currently idle following completion of their contracts in
June and September 1999,  respectively.  In preparation for a four-year contract
extension,  the  SEAHAWK  entered a shipyard in April 1999 for  upgrade,  with a
reduced dayrate paid during the upgrade period which accounts for the decline in
revenues.  The decline in revenues  for the ATWOOD  HUNTER is due to a temporary
reduction in dayrate, with an extension  in the contract  term,  during a period
when the rig could not drill due to extremely strong underwater currents. Market
conditions  resulted in a reduced  dayrate and some idle time for the  RICHMOND;
with the ATWOOD SOUTHERN CROSS idle for the entire year.

     Contract  drilling and  management   costs during  fiscal 1999  increased 8
percent from $65.3 million to $70.4  million.  An analysis of contract  drilling
and management costs by rig is as follows:

- ----------------------------------------------------------------------------


     The increase in the drilling  costs for the VICKSBURG and ATWOOD FALCON are
due to the rigs working  continuously since completing their upgrades during the
first  quarter of fiscal 1999.  The  increase in operating  costs for the ATWOOD
EAGLE was due primarily to an increase in maintenance costs and higher operating
costs associated with working the entire year in the Mediterranean Sea area. The
increase  in  operating  expense for RIG-19 was due to costs being lower in 1998
due to the  receipt  of certain  payroll  related  tax  refunds.  Reductions  in
operating costs for the RICHMOND,  RIG-200 and ATWOOD SOUTHERN CROSS were due to
cost savings associated with idle rig time.

- ------------------------------------------------------------------------------

     The increase in depreciation expense was primarily due to the commencing of
depreciation in fiscal 1999 of upgrade costs of the ATWOOD FALCON and VICKSBURG.
The Company does not recognize  depreciation  expense during the period a rig is
out of service  for a  significant  upgrade.  This  accounts  for the decline in
depreciation expense for the SEAHAWK in fiscal 1999.

Fiscal Year 1998 Versus  Fiscal Year 1997

     Despite  the ATWOOD  FALCON  and  VICKSBURG  being  idle for a  significant
portion of fiscal 1998 while undergoing upgrades, contract revenues increased 70
percent to $151.8  million  from $89.1  million.  This  increase  was  primarily
attributable to the ATWOOD HUNTER returning to work at a significant increase in
dayrate revenues  following upgrade in fiscal 1997, the initial  commencement of
drilling  operations  for the ATWOOD  SOUTHERN  CROSS  following its upgrade and
refurbishment in fiscal 1997 and the increase in dayrate revenues for the ATWOOD
EAGLE. An analysis of contract revenues by rig for fiscal years 1998 and 1997 is

     In September 1997, the ATWOOD HUNTER commenced drilling under a three-year
contract in the United States Gulf of Mexico. Due to the rig being upgraded,  it
generated less than 100 days of revenue during fiscal 1997. The ATWOOD  SOUTHERN
CROSS,  which generated no revenues prior to fiscal 1998,  commenced drilling in
Australia  in  November  1997.  The  ATWOOD  EAGLE  commenced  working  in  the
Mediterranean Sea area in March 1998, with enhanced dayrate revenues.  Due to a
strong  market  during the first half of fiscal 1998,  revenue from the RICHMOND
increased in fiscal 1998  compared to fiscal  1997.  The decline in revenues for
the VICKSBURG was due to the rig  undergoing  upgrade during most of fiscal year
1998.


     Contract  drilling and  management  costs during  fiscal 1998  increased 34
percent from $48.8 million to $65.3 million.  This increase was primarily due to
the ATWOOD  HUNTER and ATWOOD  SOUTHERN  CROSS  commencing  drilling  operations
following  their upgrades  during fiscal 1997. An analysis of contract  drilling

     The Company  acquired the ATWOOD  SOUTHERN CROSS in October  1993, but did
not place the rig into service until after the  completion of its  refurbishment
and upgrade in November  1997.  The ATWOOD HUNTER worked the entire fiscal 1998
compared to only  approximately  one  quarter of fiscal  1997.  The  increase in
operating  costs  for the  ATWOOD  EAGLE was due  primarily  to an  increase  in
maintenance  costs and higher  operating  costs  associated  with working in the
Mediterranean  Sea area as compared to West  Africa.  The  increase in operating
costs for the RICHMOND was due primarily to higher payroll  related costs.  As a
result of certain payroll related tax refunds received in fiscal 1998, operating
costs for  RIG-19  declined.  During the ATWOOD  FALCON  and  VICKSBURG  upgrade
periods,  no operating  costs are being  incurred,  resulting in lower operating
costs in the current year than in fiscal 1997.

- ------------------------------------------------------------------------

     The increase in depreciation expense was primarily due to the commencing of
depreciation  in fiscal  1998 of upgrade  costs of the ATWOOD  HUNTER and ATWOOD
SOUTHERN CROSS. The Company does not recognize  depreciation  expense during the
period a rig is out of service for a significant upgrade.  This accounts for the
decline in  depreciation  expense  for the ATWOOD  FALCON in fiscal 1998 and the
ATWOOD HUNTER in fiscal 1997.  The increase in  depreciation  expense of RIG-200
was due to the rig having  active  drilling  operations  for all of fiscal  1998
compared to only three quarters of fiscal 1997.

     General  and  administrative  expense  increased  20 percent in fiscal 1998
compared to fiscal 1997.  This increase was attributed to an increase in payroll
related costs and in  professional  fees. The $2.4 million  increase in interest
expense  was  primarily  related to the  increase  in funds  borrowed  under the
Company's  revolving credit  agreement.  With a significant  increase in pre-tax
income and  virtually  no  carryforward  tax  attributes,  both the  foreign and
domestic tax provision increased.


LIQUIDITY AND CAPITAL RESOURCES

     Even  though,  net income in fiscal 1999  declined  30 percent  from fiscal
1998,  operating cash flows (before  changes in working capital and other assets
and  liabilities)  for fiscal 1999 only declined 9 percent from $61.4 million to
$55.7  million.  During fiscal 1999,  the Company  utilized  available  cash and
internally generated funds to invest approximately $16 million in completing the
water-depth upgrade of the ATWOOD FALCON, to invest  approximately $5 million in
completing  the   refurbishment   and  upgrade  of  the  VICKSBURG,   to  invest
approximately $11 million in the upgrade of the SEAHAWK,  to fund  approximately
$7 million  in other  capital  expenditures  and to reduce  outstanding  debt by
approximately $19 million.

     Since 1997, the Company has successfully  upgraded four drilling units; the
ATWOOD HUNTER, the ATWOOD SOUTHERN CROSS, the ATWOOD FALCON and the VICKSBURG at
a cost of approximately $160 million.  Currently,  the Company is completing the
$23  million  upgrade  of the  SEAHAWK  required  for  its  four  year  contract
extension,  of  which  approximately  $20  million  will  be  reimbursed  by the
customer.  The  Company is  currently  preparing  to  increase  the  water-depth
drilling  capacity of the ATWOOD  EAGLE from 2,500 feet to  approximately  3,200
feet at a cost of  between  $8 and $10  million  and to  enhance  the  operating
performance of the RICHMOND at an estimated cost of $2.5 to $3.0 million. Except
for  funding  remaining  costs  associated  with  the  upgrade  of  the  SEAHAWK
(approximately  $12  million,   excluding   reimbursement  from  the  customer),
water-depth  upgrade of the ATWOOD EAGLE,  the RICHMOND  enhancement and general
capital  maintenance of the Company's  other rigs, the Company  currently has no
significant capital commitments.

     The Company's  revolving line of credit converted to a reducing facility at
March 31, 1999,  with  commitment  reductions  of $8.3 million per quarter until
final  maturity on March 31, 2002.  At September  30, 1999,  the reduced line of
credit  commitment  was  approximately  $100 million with an actual  outstanding
amount of $54 million,  with another $3 million  being  repaid  subsequently  to
September 30, 1999. Depending upon additional capital  investments,  anticipated
future operating cash flows are expected to continue to provide the Company with
the option of repaying  funds  borrowed  under the credit  facility prior to its
required maturity.

     Working capital increased from $24.9 million at September 30, 1998 to $31.5
million at September 30, 1999, a 27 percent increase. The Company's portfolio of
accounts receivable is comprised of major international  corporate entities with
stable  payment  experience.   Historically,  the  Company  has  experienced  no
significant  difficulties in receivable  collection;  however,  at September 30,
1999,  the Company was continuing to pursue legal action in Australia to collect
approximately $2 million billed in 1998.

     The Company  continues  to pursue  growth  opportunities.  With the Company
currently two years ahead of its required debt repayment  schedule,  the Company
would expect to finance additional capital expenditures through a combination of
operating  cash  flows or  additional  debt  financing;  however,  there  are no
assurances that additional debt financing would be available on terms acceptable
to the  Company.  The Company  continues to  periodically  review and adjust its
planned  capital  expenditures  and financing of such  expenditures  in light of
current market conditions.

YEAR 2000

     The Company has used both internal and external  resources in assessing the
Year 2000  readiness  of its  operations.  An  outside  consultant  visited  the
Company's   various  drilling  units  to  review  and  assess  their  Year  2000
compliance.  The majority of the operating  systems on its various drilling rigs
are mechanical with no Year 2000  compliance  issues;  however,  there were some
systems  that  required   assessment  and  where  necessary,   reprogramming  or
replacement.  The Company's internal  information systems have been assessed and
where necessary,  reprogrammed or replaced with fully compliant, new or modified
systems. The Company has incurred approximately $350,000 in Year 2000 assessment
costs  which has been  expensed  over the last two  years.  In  addition  to the
assessment  costs,  the  Company  has  incurred  approximately  $1.2  million in
purchasing  new software and  implementation  of an  inventory,  purchasing  and
maintenance  system  for  Year  2000  compliance,  the  cost of  which  has been
capitalized. After assessing its operations and making required modifications or
replacements,  the  Company  believes  that the Year 2000  issues  will not pose
significant operational problems;  however, the extent and magnitude of the Year
2000 problem as it will affect the Company is  difficult to predict.  Due to the
Company's international operations, foreign governments, suppliers and customers
who do not  successfully and timely achieve Year 2000 compliance could adversely
affect the Company's operations. Accordingly, there can be no assurance that the
Company will not have some disruption in its business due to Year 2000 issues.

DISCLOSURES ABOUT MARKET RISK

     The  Company  is  exposed  to market  risk,  including  adverse  changes in
interest rates and foreign currency exchange rates as discussed below.

Interest Rate Risk

     Total  long-term  debt at  September  30,  1999,  included  $54  million of
floating rate debt. As a result,  the Company's annual interest costs in fiscal
2000 will fluctuate based on interest rate changes. Because the interest rate on
the Company's long-term debt is a floating rate, the fair value of the Companys
long-term debt approximates  carrying value as of September 30, 1999. The impact
on annual cash flow of a 10 percent  change in the floating rate  (approximately
70 basis points) would be approximately  $0.4 million.  The Company did not have
any open  derivative  contracts  relating to its floating rate debt at September
30, 1999.

Foreign Currency Risk

     Certain of the Company's subsidiaries have monetary assets and liabilities
that are  denominated in a currency other than their  functional  currencies.  A
decrease  in the value of 10 percent 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  $1  million,  based on  September  30, 1999
amounts.  The Company  considers its current risk  exposure to foreign  currency
exchange rate movements,  based on net cash flows, to be immaterial. The Company
did not have any open  derivative  contracts  relating to foreign  currencies at
September 30, 1999.

                     Atwood Oceanics, Inc. and Subsidiaries
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - NATURE OF OPERATIONS

     Atwood  Oceanics,   Inc.  together  with  its  wholly  owned   subsidiaries
(collectively  referred to herein as the "Company"),  is engaged in the business
of international  offshore drilling of exploratory and developmental oil and gas
wells and related support,  management and consulting services.  Presently,  the
Company owns and operates a modern fleet of seven mobile  offshore  rigs and one
modular  platform rig, as well as manages the  operations of two  operator-owned
platform  rigs in Northwest  Australia.  The Company  also owns a fifty  percent
interest in a new generation platform rig. Currently, the Company is involved in
active  operations  in the  territorial  waters of Australia,  Malaysia,  Egypt,
Philippines, Israel, United States and India.

     Demand  for  drilling   equipment  is  dependent  on  the  exploration  and
development  programs of oil and gas companies,  which is in turn  influenced by
the financial conditions of such companies,  by general economic conditions,  by
prices of oil and gas, and from time to time,  by political  considerations  and
policies.  The Company's business operations are subject to the risks associated
with a business having a limited number of customers for which it can operate at
any given time.  A decrease in the  drilling  programs of customers in the areas
where the Company is employed may adversely affect the Company's  revenues.  The
contracts under which the Company operates its drilling rigs are obtained either
through individual  negotiations with the customer or by submitting proposals in
competition  with the other  drilling  contractors  and vary in their  terms and
conditions.  The Company competes with several other drilling contractors,  most
of which are  substantially  larger than the  Company  and  possess  appreciably
greater  financial and other resources.  Price competition is generally the most
important  factor in the drilling  industry,  but the  technical  capability  of
specialized  drilling  equipment and personnel at the time and place required by
customers  are also  important.  Other  competitive  factors  include work force
experience, rig suitability,  efficiency, condition of equipment, reputation and
customer relations. The Company believes that it competes favorably with respect
to these factors.


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation -

     The  consolidated  financial  statements  include  the  accounts  of Atwood
Oceanics,  Inc.  ("AOI")  and  all of its  wholly  owned  domestic  and  foreign
subsidiaries.  The  Company's  undivided  50  percent  interest  in  RIG-200  is
accounted  for using the  proportionate  consolidation  method (See Note 4). All
significant  intercompany  accounts and  transactions  have been  eliminated  in
consolidation.

     The U.S.  dollar is the functional  currency for all areas of operations of
the Company. Accordingly, monetary assets and liabilities denominated in foreign
currency are remeasured to U.S. dollars at the rate of exchange in effect at the
end of the year,  items of income and expense are remeasured at average  monthly
rates, and property and equipment and other  nonmonetary  amounts are remeasured
at  historical  rates.  Gains and losses on foreign  currency  transactions  and
remeasurements are included in drilling costs in the consolidated  statements of
operations.  The Company recorded a foreign exchange gain of $.4 million in 1999
and  foreign  exchange  losses of $ 1 million  and $.7 million in 1998 and 1997,
respectively.


Property and equipment -

     Property  and  equipment  is recorded at cost.  Interest  costs  related to
property  under  construction  are  capitalized  as a component of  construction
costs.  Interest capitalized during fiscal 1999 and 1998 totaled $.5 million and
$1.4 million, respectively.

     Depreciation  is provided on the  straight-line  method over the  following
estimated useful lives of the various classifications of assets:

                                                                          Years
                                                                          -----
                         Drilling vessels and related equipment            5-15
                         Drill pipe                                           3
                         Furniture and Other                               3-10

     Maintenance,  repairs and minor  replacements are charged against income as
incurred;  major  replacements and upgrades are capitalized and depreciated over
the  remaining  useful life of the asset as  determined  upon  completion of the
work. The cost and related  accumulated  depreciation of assets sold, retired or
otherwise disposed are removed from the accounts at the time of disposition, and
any  resulting  gain or loss is  reflected  in the  consolidated  statements  of
operations for the applicable period.

Deferred costs -

     The Company defers the net costs of moving a drilling rig to a new area and
amortizes  such costs on a  straight-line  basis over the life of the applicable
drilling  contract.  During  fiscal  years 1999 and 1998,  the Company  received
sufficient  mobilization  revenues  on all rig  moves  to more  than  cover  all
mobilization  costs.  Thus,  there  were no  unamortized  mobilization  costs at
September 30, 1999 or 1998.

     The Company defers the costs of scheduled drydocking and charges such costs
to  expense  over the  period  to the next  scheduled  drydocking  (normally  30
months).

Federal income taxes -

     The Company  accounts  for income  taxes in  accordance  with  Statement of
Financial  Accounting  Standards ("SFAS") No. 109 "Accounting for Income Taxes".
Under SFAS No.  109,  deferred  income  taxes are  recorded  to reflect  the tax
consequences on future years of differences  between the tax basis of assets and
liabilities  and their  financial  reporting  amounts at each year-end given the
provisions  of enacted tax laws.  Deferred tax assets are reduced by a valuation
allowance when, based upon  management's  estimates,  it is more likely than not
that a portion of the  deferred  tax  assets  will not be  realized  in a future
period.

Revenue recognition -

     The Company  accounts for drilling and management  contract  revenues using
the  percentage of completion  method of  accounting,  under which  revenues are
recognized on a daily basis as earned.  Mobilization  revenues are first used to
cover the costs of mobilization  with the excess revenues deferred and amortized
on a straight-line basis over the life of the applicable  drilling contract.  At
September 30, 1999 and 1998,  deferred revenues totaling $19.4 million and $12.3
million,  respectively,  were included in Deferred  Credits on the  accompanying
consolidated balance sheets.

Cash and cash equivalents -

     Cash and cash  equivalents  consist of cash in banks and highly liquid debt
instruments which mature within three months of the date of purchase.


Investments -

     Investments in held-to-maturity securities are stated at the amortized cost
at the balance  sheet date.  The Company has the ability and intent to hold such
securities  to  maturity.  At  September  30,  1999  and  1998,  investments  in
available-for-sale  securities  are  carried at fair  value with the  unrealized
holding loss or gain, net of deferred tax, included in comprehensive income.

Earnings per common share -

     Basic and diluted  earnings per share have been computed in accordance with
SFAS No. 128,  Earnings  per Share.  Basic  EPS,  excludes  dilution  and is
computed  by  dividing   income   available  to  common   shareholders   by  the
weighted-average  number of common shares outstanding for the period.  Diluted
EPS reflects the issuance of additional  shares in  connection  with the assumed
conversion of stock options.

     The computation of basic and diluted  earnings per share under SFAS No. 128
for each of the past three years is as follows (in thousands,  except per share
amounts):

                                                                    Per Share

Stock-Based compensation -

     The  Company  accounts  for  employee  stock-based  compensation  using the
intrinsic value method  prescribed by Accounting  Principles Board (APB) Opinion
No. 25, "Accounting for Stock Issued to Employees". Accordingly, the adoption of
SFAS No. 123,  "Accounting for Stock-Based  Compensation"  in fiscal 1996 had no
effect on the Company's results of operations.

Comprehensive income -

     In the first quarter of 1999, the Company adopted SFAS No. 130,  Reporting
Comprehensive  Income,  which  requires  companies to report the  components of
comprehensive  income in a financial statement with the same prominence as other
financial statements.  The Company has chosen to disclose  comprehensive income,
which is  comprised  of net income and  unrealized  holding  gains  (losses)  on
available  for  sale  equity  securities,   in  the  accompanying   Consolidated
Statements of Changes in Shareholders' Equity. This information is shown for all
periods presented.


Use of estimates -

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.


NOTE 3 - SECURITIES HELD FOR INVESTMENT

     All of the Company's  investments  in equity  securities  are classified as
"available-for-sale"  and  accordingly,  are reflected in the September 30, 1999
and  1998  Consolidated  Balance  Sheets  at  fair  value,  with  the  aggregate
unrealized  gain or loss,  net of  related  deferred  tax  liability  or  asset,
included in  shareholders'  equity.  All of the  Company's  investment in United
States  Treasury  Bonds  (which  mature  in 2000 and  2001)  are  classified  as
"held-to-maturity" and accordingly,  are reflected in the September 30, 1999 and
1998 Consolidated Balance Sheets at amortized cost.

NOTE 4 - PROPERTY AND EQUIPMENT

SEAHAWK -

     In 1999, the Company  commenced an approximately $23 million upgrade of the
SEAHAWK,  in compliance  with a four-year  contract  extension.  Pursuant to the
contract, the  Company  will  receive   approximately  $20  million  in  upgrade
reimbursement  payments from the customer,  of which $10 million was received at
September 30, 1999 and recorded to Deferred Credits. These upgrade reimbursement
payments,  net after  certain  costs,  will be amortized  into revenues over the
four-year contract extension period.

ATWOOD FALCON -

     In November 1998, the ATWOOD FALCON commenced drilling under its three-year
contract with Shell Philippines  Exploration B.V.,  following  completion of its
approximately  $45 million  water-depth  upgrade.  The contract provided for the
payments of $11.2 million in mobilization fees of which $10.4 million (net after
mobilization costs) was recorded to Deferred Credits and is being amortized into
revenue over the three-year contract period, with an unamortized balance of $7.0
million at September 30, 1999.




VICKSBURG -

     In  December  1998,  the  VICKSBURG  commenced  drilling  in India  under a
one-year  plus  option  contract  with  Enron  Oil & Gas India  Ltd.,  following
completion  of its  approximately  $35 million  refurbishment  and upgrade.  The
VICKSBURG contract has been extended for another year in India.

ATWOOD HUNTER -

     In fiscal 1997,  the ATWOOD HUNTER was upgraded to achieve up to 3,500 feet
water-depth  drilling capability and relocated from Southeast Asia to the United
States Gulf of Mexico at an aggregate cost of approximately $40 million. The rig
has one more year  remaining  on its  three-year  contract  with  British-Borneo
Petroleum  Inc.  The  contract  provided  for  the  payment  of  a  $10  million
mobilization  fee of which  $6.4  million  (net  after  mobilization  costs) was
recorded  to Deferred  Credits and is being  amortized  into  revenues  over the
three-year  contract  period,  with an  unamortized  balance of $2.0  million at
September 30, 1999.

ATWOOD SOUTHERN CROSS -

     During  fiscal year 1997,  the ATWOOD  SOUTHERN  CROSS was  mobilized  from
Australia to a Singapore  shipyard,  refurbished  and upgraded to achieve  2,000
feet water-depth  drilling  capability at an aggregate cost of approximately $35
million. During November 1997, the rig was mobilized from Singapore to Australia
to commence working under a contract which it completed in September 1998. While
waiting for a new contract opportunity, the rig is currently idle in Australia.

RIG 200 -

     RIG-200 (a modular  platform  rig built in 1995) is owned 50 percent by the
Company and 50 percent by Helmerich & Payne,  Inc.  (current owner of 22 percent
of the Company's  outstanding common stock).  Since the Company has a 50 percent
undivided  ownership  interest  in  RIG-200  and  is  actively  involved  in its
operations,   the  Company   accounts  for  its  investment  in  the  rig  on  a
proportionate  consolidation  method.  Accordingly,  the  Company's  $12 million
investment  in RIG-200 is reflected in "Drilling  Vessels,  Equipment  and Drill
Pipe" in the Consolidated Balance Sheets, with 50 percent of the rig's operating
results  for  fiscal  years  1999,  1998 and  1997  reflected  in the  Company's
Consolidated Statements of Operations. RIG-200 completed its initial contract in
June 1999 and is currently  idle in Australia  while  waiting for a new contract
opportunity.

     In July 1997,  the Company  entered  into a $125 million  revolving  credit
facility with a bank group. The revolving line of credit converted to a reducing
facility  on March 31,  1999,  with  commitment  reduction  of $8.3  million per
quarter until final maturity on March 31, 2002. The maximum amount  permitted to
be  outstanding  at September  30, 1999 was $100  million.  The credit  facility
permits the Company to prepay  principal at anytime without  incurring  penalty.
The  bank  group's  collateral  for  this  revolving  credit  facility  consists
principally of preferred  mortgages on the ATWOOD  HUNTER,  ATWOOD EAGLE and the
RICHMOND  plus the  assignment  of $20 million in market value of United  States
Treasury  Bonds.  The credit  facility  prohibits the Company from incurring any
additional  indebtedness  in excess of $5  million,  disposing  of any  material
assets, paying dividends or repurchasing any of the Company's outstanding common
stock.

    U.S.  deferred  taxes have not been provided on foreign  earnings  totaling
approximately $ 24.5 million which are permanently invested abroad.  Foreign tax
credits  totaling  approximately $ 12.4 million are available to reduce the U.S.
taxes on such amounts.  The differences  between the statutory and the effective
income  tax rate are  as   follows:

     The Company has United States net  operating  loss  carryforwards  totaling
$7.9 million  which expire in fiscal  years 2001  through  2003.  Due to various
utilization limitations, management estimates that a significant portion of this
tax  attribute  will  not  be  available  to  reduce  future  tax   obligations;
accordingly,  a $2.4 million valuation allowance is recorded as of September 30,
1999.

     For several years,  the Company has pursued legal action to collect certain
tax refund claims in India.  As a result of favorable  court decisions in India,
and upon the Company  providing  letters of guarantee,  the Company received tax
refunds in 1997 and 1994 of $1.1 million and $.6 million, respectively,  (net of
taxes on interest  and other  related  expenses),  which were  recorded to other
Deferred Credits, pending ultimate resolution of the issue by Indian High Court.
During fiscal year 1999, all but approximately  $400,000 of the amounts received
were favorably resolved and accordingly recognized (net of expenses) in income.

NOTE 7 - CAPITAL STOCK


STOCK OPTION PLANS -

     The Company has an  incentive  equity plan ("1996  Plan")  whereby  670,000
shares of common  stock may be granted to  officers  and key  employees  through
February 12, 2007. At September  30, 1999,  options to purchase  298,000  shares
were  outstanding  under this Plan. The Company also has options  outstanding to
purchase  206,900  shares  under a stock option plan ("1990  Plan").  Under both
plans,  the  exercise  price  of each  option  equals  the  market  price of the
Company's  common  stock on the date of grant,  all  outstanding  options have a
maximum term of 10 years,  and options vest over a period from the second to the
fifth year from the date of grant.

     A summary of the status of the  Company's  Plans as of September  30, 1999,
1998 and 1997,  and changes  during the years ended on those dates is  presented

     As permitted  by SFAS No. 123,  the Company  applies APB Opinion No. 25 and
related  Interpretations in accounting for its stock option plans.  Accordingly,
no compensation  cost has been recognized from the granting of options  pursuant
to its stock option plans. Had  compensation  costs been determined based on the
fair  value at the grant  dates for  awards  made in fiscal  years 1998 and 1997
consistent  with the  method of SFAS No.  123,  the  Company's  net  income  and
earnings  per share would have been reduced to the pro forma  amounts  indicated
below     (in     thousands,      except     for     per     share     amounts):

     The fair value of grants made in fiscal 1998 and 1997 was  estimated on the
date of grant using the  Black-Scholes  option  pricing model with the following
weighted-average  assumptions used: fiscal 1998 - risk free interest rate of 5.4
percent,  expected  volatility of 42 percent,  expected  lives of 5 years and no
dividend yield;  fiscal 1997 - risk-free interest rate of 6.7 percent,  expected
volatility of 33.6 percent, expected lives of 5 years and no dividend yield.

COMMON STOCK DIVIDEND -

     On November  19,  1997,  the Company  effected a 100 percent  common  stock
dividend  resulting in the issuance of approximately  6,775,000 shares of common
stock and the transfer of  approximately  $ 6,775,000  from  paid-in  capital to
common stock which  represented the par value of additional  shares issued.  All
share  and  per  share  information  has  been  retroactively  restated  in  the
Consolidated Financial Statements to reflect the stock dividend.

NOTE 8 - RETIREMENT PLAN

     The Company has a  contributory  retirement  plan (the "Plan")  under which
qualified participants may make contributions of up to 5% of their compensation,
as defined (the basic contribution). The Company makes contributions to the Plan
equal to twice the basic contributions.  Company  contributions vest 100 percent
to each  participant  beginning  with the  fourth  year of  participation.  If a
participant  terminates  employment  before becoming fully vested,  the unvested
portion is  credited  to the  Company's  account  and can be used only to offset
Company  contribution  requirements.  In fiscal 1999 and 1997,  the Company used
forfeitures   of  $190,000  and  $84,000   respectively,   to  reduce  its  cash
requirements,  which  resulted in actual  contributions  of  approximately  $1.3
million,  and $.9  million,  respectively.  In 1998,  the  Company  made  actual
contributions of approximately $1.3 million,  with no forfeitures used to reduce
its cash requirements.  As of September 30, 1999, there are approximately $2,000
of contribution  forfeitures which can be utilized to reduce future Company cash
contribution requirements.


NOTE 9 - FAIR VALUE OF FINANCIAL INSTRUMENTS

     The  carrying  values of cash and cash  equivalents,  accounts  receivable,
accounts   payable  and  accrued   liabilities   included  in  the  accompanying
Consolidated Balance Sheets approximated fair value due to the short maturity of
these  instruments.  Since the bank debt has a market adjustable  interest rate,
the carrying value  approximated fair value as of fiscal year end 1999 and 1998.
The Company's only  financial  instruments at September 30, 1999 and 1998 with a
fair  value  different  from  carrying  value  are  marketable  securities;  the
difference of which is shown in Note 3.



NOTE 10 - CONCENTRATION OF MARKET AND CREDIT RISK

     All of the Company's customers are in the oil and gas offshore  exploration
and production industry. This industry concentration has the potential to impact
the Company's overall exposure to market and credit risks,  either positively or
negatively, in that the Company's customers could be affected by similar changes
in economic,  industry or other conditions.  However,  the Company believes that
the  credit  risk  posed  by  this  industry  concentration  is  offset  by  the
creditworthiness  of the Company's  customer  base.  The Company's  portfolio of
accounts receivable is comprised of major  international  corporate entities and
government  organizations  with stable  payment  experience.  Historically,  the
Company's uncollectible accounts receivable have been immaterial, and typically,
the Company does not require collateral for its receivables.

     Drilling revenues for fiscal 1999 include $34.7 million,  $31.0 million and
$23.1 million in revenues received from Shell Philippines Exploration B.V./Sabah
Shell  Petroleum  Company  Limited,   British-Borneo  Petroleum  Inc.  and  ESSO
Australia  Limited/ESSO  Production  Malaysia,  Inc.,   respectively.   Drilling
revenues for fiscal 1998 include $35.2 million,  $25.9 million and $20.4 million
in  revenues  received  from  British-Borneo  Petroleum  Inc.,  ESSO  Australian
Limited/ESSO Production Malaysia, Inc. and Santos Ltd.,  respectively.  Drilling
revenues for fiscal 1997 include $24.3 million,  $19.3 million and $16.9 million
in revenues received from ESSO Australia Limited/ESSO Production Malaysia, Inc.,
Mobil Equatorial  Guinea Inc. and  Carigali-Triton  Operating Company Sdn. Bhd.,
respectively.


NOTE 11 - NEW ACCOUNTING PRONOUNCEMENTS

     The  Financial  Accounting  Standards  Board  has  issued a new  accounting
standard;  SFAS No. 137 "Accounting  for  Derivative  Instruments  and  Hedging
Activities - Defferal of the Effective  Date of FASB  Statement  No. 133".  This
Statement is effective upon issuance and is an amendment to SFAS No. 133.

     SFAS No. 133 has been amended to become  effective for all fiscal  quarters
of all fiscal years beginning after June 15, 2000. It establishes accounting and
reporting  standards  requiring  that  every  derivative  instrument  (including
certain derivative  instruments  embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair value. In the
opinion of  management,  the adoption of SFAS No.  133 will not have a material
impact on the Company's financial statements.

NOTE 12 - OPERATING LEASES

     The Company  leases its office  space under an operating  lease  agreement.
This lease has  essentially the same terms and conditions as the original lease,
and will expire in fiscal 2005.

     Future  minimum  lease  payments  for  operating  leases are as follows (in
thousands):

     Fiscal year ending September 30,
         2000........................$348
         2001........................ 408
         2002........................ 408
         2003........................ 408
         2004 and thereafter......... 578

     Total rent  expense  under  operating  leases was  approximately  $285,000,
$268,000 and $228,000 for fiscal years ended  September 30, 1999, 1998 and 1997,
respectively.


NOTE 13 - OPERATIONS BY GEOGRAPHIC AREAS

     The Company is engaged in offshore contract drilling. The contract drilling
operations  consist of contracting  Company owned or managed  offshore  drilling
equipment primarily to major oil and gas exploration companies. Operating income
is contract revenues less operating costs,  general and administrative  expenses
and depreciation.  In computing  operating margin for each geographic area, none
of the following items were considered:  other income (expense) and domestic and
foreign income taxes.  Identifiable assets are those assets that are used by the
Company in operations in each  geographic  area.  General  corporate  assets are
principally investments in marketable securities.
