                                     PART I


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.
