ITEM 1. BUSINESS

     Atwood  Oceanics,  Inc. (which together with its subsidiaries is identified
as the "Company" or  "Registrant",  unless the context  requires  otherwise),  a
corporation  organized in 1968 under the laws of the State of Texas,  is engaged
in  contract  drilling  of  exploratory  and  development  oil and gas  wells in
offshore areas and related  support,  management and  consulting  services.  The
Company  currently  owns  (i)  three  "third-generation"  semisubmersibles,  one
"second-generation"   semisubmersible,   one  jack-up,  one  "second-generation"
semisubmersible   tender   assist  rig,  one   submersible,   and  one  modular,
self-contained  platform  rig,  and  (ii)  a  50  percent  interest  in a new
generation  platform  rig.  The Company also  provides  labor,  supervisory  and
consulting services to two operator-owned platform rigs in Australia.

      In fiscal  1998,  the  Company's  revenues,  operating  cash flows and net
income were the highest in its  history.  For the last five  fiscal  years,  the
Company  has  maintained  99  percent  utilization  of its  drilling  equipment,
resulting in five consecutive years of improved  profitability.  However, during
the second half of fiscal 1998, the price for oil declined which has resulted in
some curtailment of worldwide drilling  activities,  especially for jack-ups and
shallow water drilling rigs.  Currently,  the price for oil is approximately $12
per barrel,  with worldwide  fleet  utilization for mobile offshore rigs at less
than 90 percent.

     Historically, most of the Company's drilling operations have been conducted
outside  United  States  waters.  Approximately  69,  88 and 92  percent  of the
Company's contract revenues were derived from foreign operations in fiscal years
1998, 1997 and 1996, respectively. The reduction in foreign operations in fiscal
1998 was due to a full year of  operations of the ATWOOD HUNTER in United States
waters  following  its  relocation  from  Southeast  Asia during fiscal 1997. In
addition to operating in United States waters, the Company is currently involved
in active  foreign  operations in the  territorial  waters of Australia,  Italy,
Malaysia,   India,   Egypt  and  the   Philippines.   The   ATWOOD   HUNTER,   a
third-generation semisubmersible, and the submersible RICHMOND are the Company's
only drilling vessels located in United States waters. For information  relating
to the contract revenues,  operating income and identifiable assets attributable
to specific geographic areas of operations, see Note 12 of Notes to Consolidated
Financial  Statements  contained in the Company's  Annual Report to Shareholders
for fiscal year 1998, incorporated by reference herein.

OFFSHORE DRILLING EQUIPMENT 

     The Company's diversified fleet of owned or operated
drilling rigs  currently  consists of four  semisubmersibles,  one jack-up,  one
semisubmersible  tender  assist  vessel,  one  submersible,  and  four  modular,
self-contained  platform  rigs.  Each  type  of  drilling  rig is  designed  for
different  purposes and applications,  for operations in different water depths,
bottom  conditions,  environments  and  geographical  areas,  and for  different
drilling and operating  requirements.  The following descriptions of the various
types  of  drilling  rigs  owned  or  operated  by the  Company  illustrate  the
diversified range of application of the Company's rig fleet.

     Each  semisubmersible  drilling  unit has two hulls,  the lower of which is
capable of being flooded.  Drilling equipment is mounted on the main hull. After
the drilling unit is towed to location, the lower hull is flooded,  lowering the
entire drilling unit to its operating  draft,  and the drilling unit is anchored
in place. On completion of operations,  the lower hull is  deballasted,  raising
the entire  drilling  unit to its towing  draft.  This type of drilling  unit is
designed  to operate in greater  water  depths than a jack-up and in more severe
sea  conditions  than a  drillship.  Semisubmersible  units are  generally  more
expensive to operate than jack-up rigs and,  compared to a drillship,  are often
limited in the amount of supplies that can be stored on board.

     The  semisubmersible  tender assist vessel operates like a  semisubmersible
except that its drilling  equipment  is  temporarily  installed  on  permanently
constructed offshore support platforms. The semisubmersible vessel provides crew
accommodations,   storage   facilities   and  other  support  for  the  drilling
operations.

     A jack-up drilling unit contains all of the drilling  equipment on a single
hull designed to be towed to the well site.  Once on location,  legs are lowered
to the sea floor and the unit is raised out of the water by jacking up the legs.
On  completion  of the  well,  the unit is  jacked  down,  and towed to the next
location.  A jack-up  drilling  unit can  operate in more severe sea and weather
conditions   than  a  drillship  and  is  less   expensive  to  operate  than  a
semisubmersible.  However,  because  it must  rest on the sea  floor,  a jack-up
cannot operate in as deep water as other units.

     The submersible drilling unit owned by the Company has two hulls, the lower
being a mat which is  capable  of being  flooded.  Drilling  equipment  and crew
accommodations are located on the main hull. After the drilling unit is towed to
its  location,  the lower  hull is  flooded,  lowering  the  entire  unit to its
operating draft at which it rests on the sea floor. On completion of operations,
the lower hull is deballasted, raising the entire unit to its towing draft. This
type of drilling  unit is designed to operate in shallow  water  depths  ranging
from 9 to 70 feet and can operate in moderately severe sea conditions.  Although
drilling units of this type are less expensive to operate, like the jack-up rig,
they cannot operate in as deep water as other units.

     A modular  platform  rig is similar to a land rig in its basic  components.
Modular  platform  rigs are  temporarily  installed on  permanently  constructed
offshore support  platforms in order to perform the drilling  operations.  After
the drilling phase is completed,  the modular rig is broken down into convenient
packages and moved by work boats. A platform rig usually stays at a location for
several months,  if not years,  since several wells are typically drilled from a
support platform.

DRILLING CONTRACTS

     The  contracts  under which the Company  operates  its vessels are obtained
either  through  individual  negotiations  with the  customer  or by  submitting
proposals  in  competition  with other  contractors  and vary in their terms and
conditions.  The  initial  term of  contracts  for the  Company's  owned  and/or
operated  vessels has ranged from the length of time necessary to drill one well
to several months and is generally  subject to early termination in the event of
a total loss of the drilling vessel, excessive equipment breakdown or failure to
meet minimum  performance  criteria.  It is not unusual for contracts to contain
renewal provisions at the option of the customer.

     The rate of compensation  specified in each contract  depends on the nature
of the operation to be performed,  the duration of the work, the amount and type
of equipment  and services  provided,  the  geographic  areas  involved,  market
conditions and other variables.  Generally,  contracts for drilling,  management
and support services specify a basic rate of compensation  computed on a dayrate
basis.  Such  agreements  generally  provide for a reduced  dayrate payable when
operations are interrupted by equipment  failure and subsequent  repairs,  field
moves,  adverse  weather  conditions or other factors  beyond the control of the
Company.  Some contracts also provide for revision of the specified  dayrates in
the event of material  changes in certain items of cost. Any period during which
a vessel is not earning a full operating dayrate because of the above conditions
or because the vessel is idle and not on contract will have an adverse effect on
operating  profits.  An  over-supply  of  drilling  rigs in any market  area can
adversely affect the Company's  ability to employ its drilling  vessels.  Except
for  two  rigs  idle  for  upgrades,  the  Company  had  virtually  100  percent
utilization of its drilling fleet in 1998.  However,  due to current weakness in
the worldwide offshore drilling market, the Company was unable to identify a new
contract for the ATWOOD  SOUTHERN  CROSS when it completed  its last contract at
the end of September  1998.  Despite the current market  softness and no current
contract for the ATWOOD SOUTHERN CROSS,  the Company's  contract backlog for its
third-generation  semisubmersibles  should  provide a high level of revenues and
cash flows in fiscal 1999; however,  there is no guarantee that the Company will
not experience additional equipment idle time in fiscal 1999.

      For long moves of  drilling  equipment,  the  Company  attempts  to obtain
either  a lump  sum or a  dayrate  as  mobilization  compensation  for  expenses
incurred  during the  period in  transit.  A surplus of certain  types of units,
either  worldwide or in particular  operating areas, can result in the Company's
acceptance  of a  contract  which  provides  only  partial  or  no  recovery  of
relocation  costs.  In recent  times,  the Company has received full recovery of
relocation  costs;  however,  there can be no  assurance  that this  trend  will
continue.

      Operation of the Company's  drilling  equipment is subject to the offshore
drilling requirements of petroleum exploration companies and agencies of foreign
governments.  These  requirements  are,  in turn,  subject  to  fluctuations  in
government  policies,  world demand and prices for  petroleum  products,  proved
reserves  in  relation to such demand and the extent to which such demand can be
met from onshore sources.

      The Company also  contracts to provide  various types of services to third
party owners of drilling rigs. These contracts are normally for a stated term or
until termination of operations or stages of operation at a particular  facility
or location.  The services may include, as in the case of contracts entered into
by the Company in connection with operations offshore  Australia,  the supply of
personnel and rig design, fabrication, installation and operation. The contracts
normally  provide  for  reimbursement  to  the  Company  for  all  out-of-pocket
expenses, plus a service or management fee for all of the services performed. In
most instances, the amount charged for the services may be adjusted if there are
changes in  conditions,  scope or costs of  operations.  The  Company  generally
obtains  insurance or a  contractual  indemnity  from the owner for  liabilities
which could be incurred in operations.

OPERATIONAL RISKS AND INSURANCE

      The Company's  operations are subject to the usual hazards associated with
the drilling of oil and gas wells,  such as blowouts,  explosions and fires.  In
addition,  the Company's  vessels are subject to those perils peculiar to marine
operations,  such as  capsizing,  grounding,  collision  and damage  from severe
weather conditions.  Any of these risks could result in damage or destruction of
drilling  rigs and oil and gas  wells,  personal  injury  and  property  damage,
suspension  of  operations  or  environmental  damage  through  oil  spillage or
extensive,  uncontrolled  fires.  Although  the  Company  believes  that  it  is
adequately  insured  against normal and  foreseeable  risks in its operations in
accordance  with  industry  standards,  such  insurance  may not be  adequate to
protect the Company against  liability from all  consequences of well disasters,
marine perils, extensive fire damage or damage to the environment.  To date, the
Company has not experienced difficulty in obtaining insurance coverage, although
no assurance  can be given as to the future  availability  of such  insurance or
cost thereof. The occurrence of a significant event against which the Company is
not  fully  insured  could  have a  material  adverse  effect  on the  Company's
financial position.

ENVIRONMENTAL  PROTECTION  

     Under the  Federal  Water  Pollution  Control  Act,  as  amended by the Oil
Pollution  Act of 1990,  operators of vessels in navigable  United States waters
and certain  offshore  areas are liable to the United States  government for the
costs of removing oil and certain  other  pollutants  for which they may be held
responsible,  subject  to  certain  limitations,  and must  establish  financial
responsibility  to cover  such  liability.  The  Company  has  taken  all  steps
necessary to comply with this law, and has received a  Certificate  of Financial
Responsibility  (Water  Pollution)  from the U.S.  Coast  Guard.  The  Company's
operations   in  United   States  waters  are  also  subject  to  various  other
environmental  regulations  regarding  pollution  and control  thereof,  and the
Company has taken steps to ensure compliance therewith.

CUSTOMERS

      During  fiscal  year  1998,  the  Company  performed   operations  for  13
customers.  Because of the relatively  limited number of customers for which the
Company can operate at any given  time,  sales to each of 3 different  customers
amounted to 10% or more of the Company's  fiscal 1998  revenues.  British-Borneo
Petroleum  Inc.,  Esso Australia  Limited/Esso  Production  Malaysia,  Inc., and
Santos Ltd., accounted for 24%, 17% and 14%,  respectively,  of fiscal year 1998
revenues.  The Company's business operations are subject to the risks associated
with a  business  having a  limited  number of  customers  for its  products  or
services,  and a decrease in the  drilling  programs of these  customers  in the
areas where they employ the Company may adversely affect the Company's revenues.


COMPETITION

      The Company  competes with numerous  other drilling  contractors,  most of
which are substantially  larger than the Company and possess appreciably greater
financial and other  resources.  Although  recent  business  combinations  among
drilling  companies  have  resulted  in  a  decrease  in  the  total  number  of
competitors, the drilling industry remains competitive,  with no single drilling
contractor  being dominant.  Thus, there continues to be competition in securing
available drilling contracts.

      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 is 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. If demand for drilling
rigs  increases in the future,  rig  availability  may also become a competitive
factor.  Competition  usually occurs on a regional basis and,  although drilling
rigs are mobile and can be moved  from one  region to  another  in  response  to
increased  demand,  an oversupply  of rigs in any region may result.  Demand for
drilling equipment is also dependent on the exploration and development programs
of oil  and  gas  companies,  which  are in  turn  influenced  by the  financial
condition of such companies,  by general economic  conditions,  by prices of oil
and gas, and from time to time by political considerations and policies.

FOREIGN OPERATIONS

      The  operations of the Company are conducted  primarily in foreign  waters
and are  subject to certain  political,  economic  and other  uncertainties  not
encountered  by  purely  domestic  drilling  contractors,   including  risks  of
expropriation, nationalization, foreign exchange restrictions, foreign taxation,
changing conditions and foreign and domestic monetary policies.  Generally,  the
Company purchases insurance to protect against some or all loss due to events of
political risk such as  nationalization,  expropriation,  war,  confiscation and
deprivation.  Occasionally,  customers will  indemnify the Company  against such
losses.   Moreover,   offshore  drilling  activity  is  affected  by  government
regulations  and  policies  limiting  the  withdrawal  of offshore  oil and gas,
regulations  affecting  production,  regulations  restricting the importation of
foreign  petroleum,  environmental  regulations and regulations  which may limit
operations in offshore areas by foreign companies and/or personnel.  See Note 12
to Consolidated Financial Statements contained in the Company's Annual Report to
Shareholders  for fiscal  year 1998,  incorporated  herein by  reference,  for a
summary  of  contract  revenues,  operating  income and  identifiable  assets by
geographic region.

      Because of the Company's  foreign  operations,  its overall  effective tax
rate may in the  future be  higher  than the  maximum  United  States  corporate
statutory  rate due to the  possibility  of higher  foreign tax rates in certain
jurisdictions or less than full creditability of foreign taxes paid.

EMPLOYEES

      The Company  currently  employs  approximately 700 persons in its domestic
and worldwide  operations.  In connection with its foreign drilling  operations,
the Company  has often been  required  by the host  country to hire  substantial
portions of its work force in that country and, in some cases,  these  employees
may be  represented  by foreign  unions.  To date,  the Company has  experienced
little  difficulty  in  complying  with  such  requirements,  and the  Company's
drilling  operations have not been significantly  interrupted by strikes or work
stoppages.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED SHAREHOLDER MATTERS

      As of September  30, 1998,  there were over 750  beneficial  owners of the
Company's common stock.

      The Company did not pay cash  dividends  in fiscal  years 1997 or 1998 and
the Company does not anticipate paying cash dividends in the foreseeable  future
because of the capital  intensive nature of its business.  To enable the company
to maintain its high competitive profile in the industry,  cash reserves will be
utilized,  at the appropriate time, to upgrade existing  equipment or to acquire
additional  equipment.  The Company's  revolving  credit facility  prohibits the
Company from paying dividends on common stock.

                                   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 new  generation
platform rig operating in Australia.  The Company  supports its operations  from
headquarters  in  Houston  and  affiliated   offices  in  Australia,   Malaysia,
Indonesia, Philippines, United Kingdom, Egypt, India and Italy.

TO OUR SHAREHOLDERS AND EMPLOYEES

         Operating   results  for  fiscal  1998  represent  the  Company's  best
financial performance in its thirty years of existence. Revenues, operating cash
flows (before changes in working capital and other assets and  liabilities)  and
net income increased 70%, 138% and 152%, respectively, over fiscal 1997 results.
Through the end of fiscal year 1998,  the Company has  maintained  virtually 100
percent utilization of its active drilling equipment for five consecutive years.

         Record earnings and revenues were achieved through contract renewals at
higher   dayrates   and  through  the   commencement   of   contracts   for  our
semisubmersibles  ATWOOD HUNTER and ATWOOD  SOUTHERN  CROSS  following the major
enhancement and water depth upgrade of both units.  With term contracts in place
for the ATWOOD HUNTER,  ATWOOD FALCON,  ATWOOD EAGLE and VICKSBURG,  the Company
has a healthy  contract  backlog  with  approximately  90% and 60% of  potential
revenue days for these units  already  committed for fiscal years 1999 and 2000,
respectively.  Despite current near-term  softness in the market,  the Company's
present contract  commitments should provide for a high level of revenues during
fiscal year 1999.

         The major shipyard  upgrades of the  semisubmersible  ATWOOD FALCON and
jack-up  VICKSBURG were completed during the first quarter of fiscal 1999 within
cost and completion  estimates.  The Company has now  successfully  accomplished
four major  upgrades in the past two years within cost and  completion  targets.
The  ATWOOD  FALCON,  which was  upgraded  to 3,500  ft.  water  depth  drilling
capability,  commenced a three-year contract with options to extend in Southeast
Asia during November, 1998. The VICKSBURG,  which was completely refurbished and
enhanced,  including  cantilever  conversion,  is  being  mobilized  to India to
commence a one-year  contract with options to extend during the first quarter of
fiscal 1999.  In addition,  upgrade of the GOODWYN `A'  self-contained  platform
rig,  which the Company  manages on a project basis on behalf of the owner,  was
also  completed and  commenced  drilling  operations in October,  1998 under the
Company's management.

         The ATWOOD EAGLE also recently received two additional  contracts which
require the Company to increase  the  water-depth  drilling  capacity of the rig
from 2,500 feet to 2,800 feet. These additional  contractual  obligations do not
contemplate extensive downtime for the rig and should keep the rig employed into
fiscal year 2000. The tender-assist unit SEAHAWK is also a candidate for upgrade
and  enhancement,  following  anticipated  completion  of its  current  contract
commitment in the second quarter of fiscal year 1999.  Such upgrade will only be
undertaken upon receipt of a contract commitment.

         The ATWOOD HUNTER is in the second year of a three-year contract in the
Gulf of Mexico. The submersible  RICHMOND is committed until April, 1999 and has
been continuously employed since February,  1993. We believe the RICHMOND should
be a strong candidate for ongoing work prospects,  though at reduced dayrates in
the  short  term.   In  an   improving   market   environment,   we  expect  the
semisubmersible  ATWOOD  SOUTHERN  CROSS to be a significant  contributor to the
Company's future success.

         The Company's mix of long-term contracts on high margin units,  coupled
with  short-term  contracts,  provides the potential for excellent  returns with
downside  protection  under current market  conditions and upside  potential for
enhanced  earnings  from  market   improvement.   A  strategy  of  international
operations, highly-skilled personnel, premium equipment, financial strength, and
a contract  backlog and mix  continues  to serve us well.  We remain  optimistic
about the long-term market outlook despite current near-term softness.  Striving
for  safe  operations  remains  at the  core of our  activities.  We  thank  our
employees for their efforts and  contributions,  and our  shareholders for their
support.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


     This Annual Report to Shareholders and the related Form 10-K for the fiscal
year ended September 30, 1998 includes  "forward-looking  statements" within the
meaning of Section 27A of the  Securities  Act of 1933, as amended,  and Section
21E of the Securities  Exchange Act of 1934, as amended.  All  statements  other
than statements of historical facts included in this report and the related Form
10-K regarding the Company's financial position,  business strategy, budgets and
plans and  objectives of management for future  operations  are  forward-looking
statements.  Although the Company  believes that the  expectations  reflected in
such  forward-looking  statements are reasonable,  it can give no assurance that
such  expectations  will  prove  to have  been  correct.  These  forward-looking
statements  involve risks and uncertainties  that may cause the Company's actual
future  activities  and results of operations to be  materially  different  from
those suggested or described in this Annual Report to  Shareholders  and related
Form 10-K.  These risks  include:  the  Company's  dependence on the oil and gas
industry; the Company's ability to secure adequate financing; the risks involved
in the construction and upgrade to the Company's rigs;  competition;  operations
risks;  risks involved in foreign  operations;  and governmental  regulation and
environmental matters. These factors ("Cautionary  Statements") are disclosed in
various places  throughout this report and the related Form 10-K. All subsequent
written and oral  forward-looking  statements  attributable  to the Company,  or
persons acting on its behalf,  are expressly  qualified in their entirety by the
Cautionary Statements.

OUTLOOK

     In fiscal 1998, the Company's revenues, operating cash flows and net income
were the highest in its history.  Except for rigs idle for upgrades, the Company
had 100  percent  utilization  of its  drilling  fleet in  fiscal  1998.  At the
beginning  of fiscal  1998,  the price for oil was around $20 per  barrel,  with
worldwide  fleet  utilization  for mobile offshore rigs in excess of 95 percent.
During the second half of fiscal 1998, the price for oil declined which resulted
in some curtailment of worldwide  drilling  activities,  especially for jack-ups
and shallow water drilling rigs. Currently,  the price for oil is around $12 per
barrel,  with worldwide fleet  utilization for mobile offshore rigs at less than
90 percent.

    Due to current  weakness in the  worldwide  offshore  drilling  market,  the
Company was unable to identify an ongoing contract for the ATWOOD SOUTHERN CROSS
when it completed its last contract at the end of  September,  1998.  Currently,
the ATWOOD SOUTHERN CROSS is the Company's only rig not generating revenues.  In
an  improved  market  environment,  the  Company  is  confident  that the ATWOOD
SOUTHERN CROSS will be a significant contributor to future revenues. Despite the
current market  softness and no current  contract for the ATWOOD SOUTHERN CROSS,
the Company's contract backlog for its third-generation  semisubmersibles should
provide a high level of  revenues  and cash flows in fiscal  1999.  The  Company
remains  confident in the long-term  future of the worldwide  offshore  drilling
market.


RESULTS OF OPERATIONS

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
as follows:

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

     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 was relocated from West Africa to
the  Mediterranean  Sea  area in  March,  1998  and  commenced  working  under a
rig-sharing agreement, with enhanced dayrate revenues. The ATWOOD FALCON entered
a shipyard in May,  1998 for its  water-depth  upgrade,  which was not completed
until November,  1998.  Revenues from the rig should be significantly  higher in
fiscal  1999.  Due to a strong  market  during  the first  half of fiscal  1998,
revenues  from the RICHMOND  increased  in fiscal 1998  compared to fiscal 1997.
However,  due to current softness in the market, there has been a recent decline
in dayrate for the rig and, therefore, it is expected to generate less revenues
in fiscal 1999 than in fiscal 1998.

     Stable contracts for the SEAHAWK,  RIG-200 and RIG-19 provided  consistency
to operations during fiscal 1998.  Contractual work for RIG-200 and RIG-19 could
terminate during fiscal 1999 with an uncertainty for ongoing work. The VICKSBURG
entered a shipyard in December, 1997 for refurbishment and upgrade which was not
completed until November, 1998, and this accounted for its decrease in revenues.
Drilling  activity for the GOODWYN `A' declined during the second half of fiscal
1998 due to its  Australian  owner  upgrading  the  rig.  The  Company  provided
additional  labor to NORTH RANKIN `A' and is expected to continue to be involved
in the operation of both rigs at least into the year 2000.
     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
and management costs by rig is as follows:

     The  ATWOOD   HUNTER  worked  the  entire  fiscal  1998  compared  to  only
approximately  one  quarter of fiscal  1997.  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
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.  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. As a result of certain payroll related tax refunds received
in fiscal  1998,  operating  costs for RIG-19  declined.  The  increase in NORTH
RANKIN `A' costs and the  decrease  in GOODWYN `A' costs were due to an increase
in  personnel  services  provided  to the NORTH  RANKIN  `A',  and a decrease in
services provided to GOODWYN `A' during its upgrade period.

     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.

Fiscal Year 1997 Versus Fiscal Year 1996

     Contract revenues in fiscal 1997 increased 12 percent to $89.1 million from
$79.5 million. This increase was primarily  attributable to dayrate increases on
the ATWOOD FALCON,  ATWOOD EAGLE and RICHMOND,  to an increase in labor services
provided to NORTH RANKIN 'A' and to a complete year of revenues from RIG-200. An
analysis of contract revenues by rig for fiscal 1997 and 1996 is as follows:

     Contracts which commenced during the last half of fiscal 1996 by the ATWOOD
FALCON  and  ATWOOD  EAGLE,   and  which   resulted  in  dayrate   increases  of
approximately 60 percent and 25 percent,  respectively,  extended through fiscal
1997,  accounting for the increase in revenues for these rigs. The ATWOOD HUNTER
entered the shipyard in December,  1996 for its deep water upgrade which was not
completed until September, 1997, accounting for its decrease in revenues. A full
year of revenues  coupled  with the  commencement  of active  drilling at higher
dayrates  accounted for the increase in revenues for RIG-200.  Stable  contracts
for the SEAHAWK and VICKSBURG  provided  consistency  to these  operations.  The
decline in revenues  for RIG-19 was due to the rig being moved to a new platform
during  fiscal  1997 with no revenues  being  recognized  during the  relocation
period.  Market  conditions  for the RICHMOND also  improved  during fiscal 1997
resulting in increased revenues.

     In  contrast  to a 12  percent  increase  in  contract  revenues,  contract
drilling  and  management  costs in fiscal  1997  decreased  5 percent  to $48.8
million from $51.5  million.  The decrease was  primarily  due to the absence of
drilling  costs on the ATWOOD HUNTER during its upgrade  period.  An analysis of
contract drilling and management costs by rig is as follows:

   The ATWOOD HUNTER was out of service for approximately eight months in fiscal
1997 due to the upgrade  period.  The  increase in costs of RIG-200 was due to a
full  year of  operations.  The  decrease  in costs  for  RIG-19  was due to its
relocation  to a  new  platform  which  resulted  in  no  drilling  costs  being
recognized during the relocation period. The increase in operating costs for the
ATWOOD  EAGLE,  SEAHAWK,  VICKSBURG  and NORTH RANKIN 'A' were due  primarily to
higher payroll related costs.

     With the ATWOOD  HUNTER out of service for drilling  operations  during its
water depth enhancement, no depreciation was recognized during the rig's upgrade
period.  Depreciation  of RIG-200  commenced  upon  start-up of active  drilling
operation in January, 1997.

     General  and  administrative  expense  increased  19 percent in fiscal 1997
compared  to fiscal  1996.  This  increase  was  attributable  to an increase in
payroll  related costs and to  professional  fees associated with a registration
statement  filed with the Securities and Exchange  Commission in February,  1997
with respect to a public offering of 1.5 million shares of the Company's  common
stock,  which  was  subsequently  withdrawn  due to the  stock  price  range not
adequately  reflecting  the value of the  Company.  Investment  income in fiscal
years  1997 and 1996 of $2.4  million  and $2.5  million,  respectively,  offset
interest  expense  for both  years.  With an  increase  in  pre-tax  income  and
virtually  no  carryforward  tax  attributes,  both  foreign  and  domestic  tax
provisions significantly increased.


LIQUIDITY AND CAPITAL RESOURCES

     During fiscal 1998, operating cash flows (before changes in working capital
and other assets and  liabilities)  increased  138 percent from $25.8 million to
$61.4  million.  During  fiscal  1998,  the  Company  utilized  available  cash,
internally generated funds and $14 million of funds borrowed under its revolving
credit facility to invest  approximately $30 million in the water-depth  upgrade
of the ATWOOD FALCON,  to invest  approximately $30 million in the refurbishment
and upgrade of the VICKSBURG,  to invest approximately $13 million in completing
the  refurbishment  and  upgrade  of the  ATWOOD  SOUTHERN  CROSS  and  to  fund
approximately $7 million in other capital expenditures.

     After  enhancing the ATWOOD FALCON to drill in up to 3,500 feet of water at
an  approximate  cost of $50 million,  of which $30 million was expended  during
fiscal 1998, the rig commenced drilling under a three-year contract in November,
1998.  After the  Company  committed  approximately  $35  million to upgrade and
refurbish the VICKSBURG  (including  cantilevering  for extended reach drilling,
adding  a top  drive  and  enhancing  certain  drilling  equipment),  the rig is
preparing to mobilize to India to commence a one-year contract.  Currently,  the
Company has two other rigs,  the SEAHAWK and ATWOOD EAGLE,  which are candidates
for upgrades. A contract extension is currently being discussed for the SEAHAWK,
which is a  requirement  before any upgrade will be  undertaken.  The Company is
contractually  obligated to increase the  water-depth  drilling  capacity of the
ATWOOD  EAGLE from 2,500 feet to 2,800  feet.  This  minimum  upgrade  will cost
approximately $4 million and will not require the use of a shipyard or result in
extensive  downtime for the rig.  Thus,  except for funding the remaining  costs
associated  with the upgrades of the ATWOOD FALCON and VICKSBURG  (approximately
$25  million),   minimal  upgrade  of  the  ATWOOD  EAGLE  and  general  capital
maintenance  of  the  Company's  other  rigs,  the  Company   currently  has  no
significant capital commitments.

     Since September 30, 1998, the Company has borrowed another $8 million under
its revolving credit facility,  resulting in a current outstanding balance under
the  facility  of  $80  million.  Subject  to an  investment  opportunity  being
identified,  the Company estimates that it will not  significantly  increase the
outstanding  balance under this facility.  The ATWOOD HUNTER,  ATWOOD EAGLE, and
RICHMOND plus $20 million of the  Company's  United  States  Treasury  bonds are
pledged as collateral under the $125 million  revolving  credit  facility.  This
revolving line of credit converts to a reducing facility commencing on March 31,
1999, with commitment reduction of $8.3 million per quarter until final maturity
on March 31, 2002.  Depending upon additional capital  investments,  anticipated
future  operating cash flows are expected to provide the Company with the option
of repaying  funds  borrowed  under the revolving  credit  facility prior to its
required maturity.

     For the last quarter of fiscal 1998, the Company earned  approximately  $35
million in contract  revenues compared to approximately $24 million for the last
quarter of fiscal 1997. This significant  increase in contract revenues accounts
for the $11.4  million  increase in accounts  receivable  at September  30, 1998
compared to September 30, 1997. The Company's  portfolio of accounts  receivable
is comprised  of major  international  corporate  entities  with stable  payment
experience.  Historically,  the  Company  has  experienced  no  difficulties  in
receivable  collections;  however,  at September  30, 1998,  there is a contract
dispute over  approximately  $2 million billed in September 1998. The Company is
in the process of taking legal action to collect this $2 million.

     The  Company  continues  to pursue  additional  growth  opportunities.  The
current decline in drilling market activity may enhance the Company's ability to
identify investment alternatives. The Company would expect to finance additional
capital expenditures  through a combination of operating cash flows,  additional
borrowing  under the revolving  credit  facility or additional  debt  financing;
however,  the Company can give no assurance 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

     Many computer software  systems,  as well as certain hardware and equipment
utilizing  date-sensitive  data,  were  structured to use a two-digit date field
meaning that they will not be able to properly recognize dates in the Year 2000.
The Company is using both  internal and  external  resources to assess and where
necessary,  to reprogram,  replace or test software for Year 2000 Compliance.  A
majority of the  Company's  internal  information  systems are in the process of
being  reprogrammed or replaced with  fully-compliant  new or modified  systems.
Most of the  Company's  operating  systems  on its  various  drilling  rigs  are
mechanical, with no Year 2000 compliance issues; however, there are some systems
that will require  assessment and possible  reprogramming  or  replacement.  The
Company is  striving  to address  and,  where  necessary,  correct all Year 2000
issues by the end of June 1999.  Currently,  the total cost of assessments,  new
software  and  implementations  is  estimated  to be between  $1 million  and $2
million, most of which will relate to new software and will be capitalized.  The
Company believes that with  modifications to existing software and conversion to
new  software,  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.  Accordingly,  there can be no
assurance that the Company will adequately correct all Year 2000 problems, so as
not to create  disruptions  in the  Company's  business.  The  Company  does not
currently  have   information   concerning  the  Year  2000  compliance  of  its
significant  customers or suppliers.  In the event the Company's major suppliers
or customers do not successfully  and timely achieve Year 2000  compliance,  the
Company's operations will be adversely affected.

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,  1998,  included  $72  million of
floating rate debt. As a result,  the Company's  annual interest costs in fiscal
1999 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 Company's
long-term debt approximates  carrying value as of September 30, 1998. The impact
on annual cash flow of a 10 percent  change in the floating rate  (approximately
70 basis points) would be approximately  $0.5 million.  The Company did not have
any open  derivative  contracts  relating to its floating rate debt at September
30, 1998.

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, 1998
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, 1998.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Board of Directors of Atwood Oceanics, Inc.:

     We have  audited the  accompanying  consolidated  balance  sheets of Atwood
Oceanics,  Inc. (a Texas  corporation) and subsidiaries as of September 30, 1998
and 1997, and the related consolidated statements of operations,  cash flows and
changes in shareholders'  equity for each of the three years in the period ended
September 30, 1998.  These financial  statements are the  responsibility  of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on our audits.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion,  the financial statements referred to above present fairly,
in all material respects,  the financial  position of Atwood Oceanics,  Inc. and
subsidiaries  as of  September  30,  1998 and  1997,  and the  results  of their
operations  and their cash flows for each of the three years in the period ended
September 30, 1998, in conformity with generally accepted accounting principles.

                     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, Italy, 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.

Foreign exchange -

     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 incurred foreign exchange losses of $ 1 million and $.7
million  in 1998 and 1997,  respectively,  with a foreign  exchange  gain of $.2
million in 1996.


<PAGE>


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 1998 and 1997 totaled $1.4 million and
$1.3 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 1998 and 1997,  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, 1998 or 1997.

     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, 1998 and 1997,  deferred  revenues totaling $12.1 million and $9.3
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.


<PAGE>



Receivables -

     Based upon the Company's historical collection of accounts receivable,  the
Company has not established an allowance for doubtful accounts.

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,  1998  and  1997,  investments  in
available-for-sale  securities  are  carried at fair  value with the  unrealized
holding loss, net of deferred tax, included in shareholders' equity.

Earnings per common share -

     In fiscal 1998,  the Company  adopted SFAS No. 128,  "Earnings  per Share".
Under SFAS No. 128,  primary  earnings per share  ("EPS") is replaced by "Basic"
EPS, which  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.  As  required,  all
prior-period EPS information has been restated.

     The computation of basic and diluted  earnings per share under SFAS 128 for
each of the past three  years is as  follows:  (in  thousands,  except per share
amounts)

                                                               Per Share

     Diluted earnings per share          $ 11,368     13,544     $   .84
=========================================================================

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.


<PAGE>


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, 1998
and  1997  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, 1998 and
1997 Consolidated Balance Sheets at amortized cost.

     There were no sales of securities during fiscal 1998 or 1997. During fiscal
1996, 32,000 shares of Mobil Corporation common stock were sold for $3.7 million
and  resulting in realized  gains,  using  average  cost,  of $2.8  million.  An
analysis of the Company's investment in marketable  securities is as follows (in
thousands):

NOTE 4 - PROPERTY AND EQUIPMENT

VICKSBURG  -

     In  December,  1997,  the  VICSKSBURG  was  mobilized  from  Australia to a
Singapore  shipyard  to undergo an  approximate  $35 million  refurbishment  and
upgrade project, of which $30 million was expended during fiscal 1998. Following
completion  of this project in  November,  1998,  the rig is being  mobilized to
India to commence a one-year plus option contract.

ATWOOD FALCON -

     In June,  1998,  the ATWOOD  FALCON was  relocated  from  Philippines  to a
Singapore shipyard to undergo an approximately $50 million water-depth  upgrade,
of which $30 million was expended  during fiscal 1998.  Following  completion of
the  project  in  November,  1998,  the rig has  commenced  drilling  under  the
three-year phase two portion of its 1996 contract. Pursuant to the contract, the
Company will receive $11.2 million in  mobilization  fees, of which $6.3 million
was received at September 30, 1998 and recorded to Deferred Credits. These fees,
net  after  mobilization  costs,  will  be  amortized  into  revenues  over  the
three-year contract period.


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.


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 two more years  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 $4.2  million at
September 30, 1998.

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 Sheet, with 50 percent of the rig's operating
results  for  fiscal  years  1998,  1997 and  1996  reflected  in the  Company's
Consolidated  Statement of Operations.  At September 30, 1998,  Accounts Payable
included  approximately  $950,000 payable to Helmerich & Payne, Inc. relating to
RIG-200 operations, which the Company paid in October, 1998.

    In July,  1997,  the Company  entered into a $125 million  revolving  credit
facility with a bank group.  The revolving line of credit converts to a reducing
facility commencing on March 31, 1999, with commitment reduction of $8.3 million
per quarter until final maturity on March 31, 2002. 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 assigment 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.  The proceeds  borrowed  under this
revolving  credit  facility have been used to repay the notes payable to a prior
bank group and to fund capital expenditures.

    The Company has United States net operating loss carryforwards totaling $8.2
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,
1998.

    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  expense),  which are  reflected  in the
September  30,  1998 and 1997  Consolidated  Balance  Sheets  as other  Deferred
Credits, pending ultimate resolution of the issue by the Indian High Court.

    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,  1997 and
1996  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):

                                             Fiscal       Fiscal      Fiscal
                                              1998         1997        1996
                                           ---------   ----------  ----------
Net Income             As reported         $ 39,364     $ 15,619    $ 11,368
                       Pro forma             38,830       15,404      11,291
Earnings per share     As reported -
                         Basic                 2.90         1.16         .85
                         Diluted               2.84         1.14         .84

The fair value of grants made in fiscal 1998, 1997 and 1996 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;
fiscal 1996 - risk-free  interest  rate of 5.8 percent,  expected  volatility of
33.7 percent, expected lives of 5 years and no dividend yield.

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  1998,  the  Company  made cash
contributions  of  approximately  $1.3  million  to the  Plan  and  utilized  no
fortfeitures to reduce its contribution  requirements.  In fiscal 1997 and 1996,
the Company used forfeitures of $84,000 and $58,000, respectively, to reduce its
cash requirements,  which resulted in actual  contributions of approximately $.9
million and $.7  million,  respectively.  As of September  30,  1998,  there are
approximately  $100,000  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 1998 and 1997.
Although  the $.7  million  term  note has a fixed 6  percent  interest  rate at
September  30,  1998,  it also  approximated  fair  value.  The  Company's  only
financial instruments at September 30, 1998 and 1997 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 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. Drilling revenues for fiscal 1996 include $25.6
million, $11.5 million and $8.4 million in revenues received from Esso Australia
Limited/Esso Production Malaysia, Inc.,  Carigali-Triton  Operating Company Sdn.
Bhd. and Mobil Equatorial Guinea Inc., respectively.

NOTE 11  - NEW ACCOUNTING PRONOUNCEMENTS

     The Financial  Accounting  Standards  Board has issued four new  accounting
standards;  SFAS  No.  130  "Reporting  Comprehensive  Income";  SFAS  No.  131,
"Disclosures  about Segments for Enterprise and Related  Information";  SFAS No.
132,  "Employer's  Disclosure about Pension and Other Post Retirement  Benefits"
and  SFAS  No.  133,   "Accounting   for  Derivative   Instruments  and  Hedging
Activities".  SFAS 130, 131 and 132 are  effective  for fiscal  years  beginning
after  December  15,  1997.  SFAS 130  requires  the  reporting  and  display of
comprehensive  income. While the Company does have certain  comprehensive income
items,  this standard will not affect the Company's  reported  consolidated  net
income or cash flows. SFAS 131 establishes standards for reporting financial and
description  information  about a company's  operating  segments.  Management is
currently  analyzing the impact of SFAS 131, but does not expect the standard to
materially  change its  current  segment  disclosure.  SFAS 132 is a  disclosure
oriented standard and will not affect the Company's reported consolidated income
or cash flows.  SFAS 133 is effective for fiscal years  beginning after June 14,
1999. This Statement  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  Statement  133 will not have a  material  impact on the  Company's
financial statements.


NOTE 12 - 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.

A summary of revenues,  operating margin and  identifiable  assets by geographic
areas is as follows (in thousands):
