                                   The ATWOOD HUNTER (built in 1981) is
                                   currently undergoing a substantial
                                   upgrade that will enable the rig to
                                   operate in 3,500 feet of water with a
                                   deckload capacity in excess of 3,000
                                   short tons. Semisubmersible drilling
                                   units have 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
       [PHOTO]                     location, the lower hull is ballasted,
                                   lowering the entire drilling unit to its
                                   operating draft, and the drilling unit
                                   is anchored in place. This type of
                                   drilling unit is designed to operate in
                                   greater water depths than a ja ck-up and
                                   in more severe sea conditions than a
                                   drillship. Upon completion of phase-one
                                   of the upgrade (estimated April 1997),
                                   the rig will be dry transported to the
                                   United States for completion of the
                                   upgrade, with drilling operations

                                   contract (estimated November 1997), the 
                                   rig will be mobilized to the Philippines 
                                   to commence drilling under a contract which
                                   provides for drilling of two initial
                                   wells, with an option for three years of
                                   drilling operations in up to 3,500 feet
       [PHOTO]                     of water in the Philippines' South
                                   China Sea. If the option is exercised,
                                   the rig will undergo a substantial
                                   upgrade to enable the rig to operate in
                                   3,500 feet of water with a deckload
                                   capacity in excess of 3,000 short tons
                                   which will take six to seven months to

     THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY AND SHOULD BE READ IN
CONJUNCTION WITH THE MORE DETAILED INFORMATION AND CONSOLIDATED FINANCIAL
STATEMENTS, INCLUDING THE NOTES THERETO, APPEARING ELSEWHERE OR INCORPORATED BY
REFERENCE IN THIS PROSPECTUS. UNLESS OTHERWISE INDICATED, THE INFORMATION IN
THIS PROSPECTUS ASSUMES NO EXERCISE OF THE UNDERWRITERS' OVER-ALLOTMENT OPTION.
IN ADDITION, UNLESS OTHERWISE SPECIFIED, THE FINANCIAL AND OTHER OPERATING DATA
PERTAINING TO THE COMPANY SET FORTH HEREIN ARE REFLECTED ACCORDING TO THE
COMPANY'S FISCAL YEAR WHICH ENDS SEPTEMBER 30.

                                  THE COMPANY

     The Company provides offshore contract drilling services to the oil and gas
industry. The Company's diversified rig fleet consists of eight wholly-owned
rigs, including three third-generation semisubmersibles, one second-generation
semisubmersible, one jack-up, one second-generation semisubmersible
tender-assist vessel, one submersible and one modular self-contained platform
rig, and a fifty percent interest in a newly-constructed platform rig. The
Company's fleet is currently operating in Australia, Southeast Asia, Equatorial
Guinea and the United States. The Company also provides management, labor and
supervisory services pursuant to contracts for two operator-owned drilling and
production platforms.

     In fiscal 1996, the Company maintained 100% utilization of its drilling
rigs placed in service, and the Company maintained a utilization rate in excess
of 99% for each of the past three fiscal years. Improved financial results for
the Company in fiscal 1996 reflect continued high rig utilization coupled with
significant dayrate increases for several of the Company's rigs, which were
achieved primarily during the second half of 1996. The Company has recently been
awarded two substantial rig upgrade contracts, and based upon contract
commitments, the Company expects to maintain a high level of utilization of its
remaining rigs during fiscal 1997.

     Financial results for the first quarter of fiscal 1997 reflect the impact
of significant dayrate increases realized for several of the Company's rigs.
Contract revenues and earnings before interest expense, taxes and depreciation
for the three months ended December 31, 1996 increased 22% and 85%,
respectively, compared to the three months ended December 31, 1995.

                                MARKET OVERVIEW

     During the last two years, offshore drilling activity has substantially
increased, raising the utilization of the worldwide offshore rig fleet to 92% as
of December 31, 1996, from 82% as of the beginning of 1995. The increase in
activity has been particularly strong in the semisubmersible market, in which
utilization has increased from 79% at the beginning of 1995 to 94% as of
December 31, 1996. The recent levels of offshore rig utilization represent the
highest levels in more than 10 years, driven in part by technological advances
in areas such as subsea completions, floating production systems, horizontal
drilling and 3-D seismic which have led to increased demand for drilling rigs
with deeper water capabilities. During this period, the Company has achieved
significant dayrate increases and secured longer terms for its contracts. The
Company has secured two substantial rig upgrade contracts, and the Company
executed a contract in January 1997 which, if an option is exercised, will
result in a third substantial rig upgrade. The Company is actively pursuing
additional rig upgrade opportunities.

                               BUSINESS STRATEGY

     The Company seeks to enhance shareholder value and maximize profitability,
rig utilization and dayrate margins through (i) upgrading the performance
capabilities of its rig fleet, (ii) operating a diversified rig fleet with an
international focus, (iii) seeking growth opportunities through rig acquisitions
and new rig construction, (iv) maximizing flexibility through conservative
financial management, and (v) maintaining a quality reputation for customer
service and safety.

     RIG FLEET UPGRADES -- The Company is capitalizing on opportunities to
enhance its rig fleet to take advantage of increased market dayrates for rigs
with deeper water drilling capabilities. The Company believes it can generate
significantly higher dayrates with increased operating margins by upgrading the
water depth drilling capabilities and deckload capacities of its rigs, thereby
earning a higher rate of return on investment.

     The ATWOOD HUNTER is currently undergoing a substantial upgrade at a cost
of approximately $45 million. This upgrade will increase the deckload capacity
of the rig and enable the rig to operate in 3,500 feet of water. The upgrade is
undertaken in connection with a three-year contract for drilling operations in
the Gulf of Mexico, under which the ATWOOD HUNTER is expected to commence
drilling operations in the fourth quarter of fiscal 1997. The contract provides
for a $10 million mobilization fee which offsets a portion of the Company's
upgrade and mobilization costs.

     In January 1997, the Company was awarded a 175-day drilling contract for
the ATWOOD SOUTHERN CROSS, which has been stacked in Australia since it was
acquired for $1.5 million in fiscal 1994. The rig should be mobilized to
Singapore in March 1997 to undergo substantial refurbishment and upgrade at a
total cost of approximately $25 million in order to achieve up to 2,000 feet
water depth drilling capability. Upon completion of the refurbishment and
upgrade, the rig will commence drilling operations in Australia in late fiscal
1997 or early fiscal 1998.

     Following completion of the ATWOOD FALCON's current contract (estimated
November 1997), the rig will be mobilized to the Philippines to commence
drilling under a contract which provides for drilling of two initial wells
(estimated 90 days duration), with an option (which may be exercised on or
before June 30, 1997) for three years of drilling operations in up to 3,500 feet
of water in the Philippines' South China Sea. In the event the option is
exercised, the rig will be transported to a shipyard following completion of the
initial two well program to undergo an upgrade at a cost of approximately $50
million, which would be partially offset by a $10 million mobilization fee.
Management estimates that the upgrade and mobilization will take six to seven
months to complete.

     The ATWOOD EAGLE is a candidate for similar upgrade opportunities in late
fiscal 1998 or thereafter. Potential customer requirements and the renewal of
option terms on the ATWOOD EAGLE will determine the extent of and timing for any
such upgrade.

     The VICKSBURG, a 300 foot water depth rated jack-up rig currently working
in production mode in Australia, is also a candidate for upgrade in fiscal 1998.
Depending on contract opportunities and potential customer requirements, the
Company's options upon completion of the current contract, which could extend to
January 1998, include returning the rig to drilling mode at a cost of
approximately $3 million or undertaking a substantial upgrade at a cost ranging
from $10 to $30 million, depending on the extent of the upgrade. The Company
estimates that expenditures of approximately $30 million would enable the rig to
be upgraded to provide for increased leg lengths, cantilever extended reach
drilling with a top drive, increased deckload capacity and other enhanced
drilling capabilities.

     DIVERSIFIED OPERATIONS AND INTERNATIONAL FOCUS -- The Company's fleet
consists of six mobile drilling rigs, including four semisubmersibles, one
jack-up and one submersible, as well as two platform rigs and a semisubmersible
tender-assist vessel. The Company also provides management, labor and
supervisory services pursuant to contracts for two operator-owned drilling and
production platforms. The Company has been active in the Australian and
Southeast Asian markets since 1970, and the Company's international operations
in Australia, Southeast Asia and Equatorial Guinea accounted for over 92% of its
fiscal 1996 revenues. Offshore drilling activities in these markets continue to
increase as advances in technology (including subsea completions, floating
production systems, horizontal drilling and 3-D seismic), growth in market
demand for oil and gas, and expansion of local market transportation and
processing infrastructures improve the economics of offshore exploration and
production.

     GROWTH OPPORTUNITIES -- The Company has historically grown its fleet
through both rig acquisitions and new rig construction. In fiscal 1990, the
Company significantly enhanced the size and quality of its fleet by acquiring a
50% interest in three third-generation semisubmersible rigs, the ATWOOD FALCON,
ATWOOD EAGLE and ATWOOD HUNTER. In fiscal 1995, the Company acquired the
remaining 50% interest in these three rigs. In fiscal 1994, the Company expanded
its fleet by acquiring a second-generation semisubmersible rig, the ATWOOD
SOUTHERN CROSS. The Company participated in the design and fabrication of a
new-generation platform rig, RIG-200, through a 50/50 joint venture with a
subsidiary of Helmerich & Payne, Inc. RIG-200 commenced operations in January
1997 pursuant to a contract with Esso Australia Limited for drilling operations
in the West Tuna field offshore Australia. The Company continues to seek
opportunities to invest in rig acquisitions and new rig construction.

     CONSERVATIVE FINANCIAL MANAGEMENT -- The Company maximizes its flexibility
to pursue upgrade and other growth opportunities by limiting its debt position
as well as maximizing its margins and internal cash flow through strict cost
control. The Company's management systems include detailed real-time tracking of
costs associated with the mobilization and ongoing operations of its rigs,
thereby allowing the Company to maximize profitability under the terms of its
contracts in all geographic areas of operation. After the Offering, the Company
will have less than $2 million of outstanding debt.

     QUALITY REPUTATION -- The Company is an experienced, safety-conscious
contract driller and has built long-term customer relationships with several of
the largest and most active operators of offshore oil and gas properties,
including U.S. and foreign integrated and independent oil and gas companies.
Over the last two fiscal years, the Company's high-quality customer base has
included Esso Australia Limited and Esso Production Malaysia, Inc. (33% of total
revenues over the period), BHP Petroleum Pty. Ltd. (11%), Carigali-Triton
Operating Company Sdn. Bhd. (10%), Woodside Offshore Petroleum Pty. Ltd., an
Australian company affiliated with Shell, British Petroleum, BHP Petroleum,
Chevron and Mitsubishi (10%), Mobil Equatorial Guinea Inc. (6%), and Shell
Offshore, Inc. (5%). The Company has received extensive customer recognition for
the safety of its contract drilling operations and completed fiscal 1996 without
experiencing a lost-time accident.

                                  RISK FACTORS

     Prospective investors should consider carefully the following factors, in
addition to the other information contained or incorporated by reference in this
Prospectus.

FORWARD LOOKING INFORMATION

     This Prospectus includes "forward-looking statements" within the meaning
of Section 27A of the Securities Act of 1933, as amended (the "Securities
Act") and Section 21E of the Exchange Act. All statements other than statements
of historical facts included in this Prospectus 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. Important factors that could cause actual results to
differ materially from the Company's expectations ("Cautionary Statements")
are disclosed in the additional risk factors set forth below, in "Management's
Discussion and Analysis -- Liquidity and Capital Resources" and elsewhere in
this Prospectus and the documents incorporated herein by reference. 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.

DEPENDENCE ON OIL AND GAS INDUSTRY; INDUSTRY CONDITIONS

     The Company's operations are materially dependent upon the levels of
activity in offshore oil and natural gas exploration, development and
production. Such activity levels are affected by, among other factors,
short-term and long-term trends in oil and natural gas prices. Historically, the
prices for oil and natural gas have been volatile and are subject to wide
fluctuations in response to changes in the supply and demand for oil and natural
gas, market uncertainty and a variety of political, economic and other factors
beyond the control of the Company. Worldwide military, political and economic
events, including initiatives by the Organization of Petroleum Exporting
Countries, have contributed to, and are likely to continue to contribute to,
price volatility. The Company cannot predict future oil and natural gas price
movements with any certainty. Any prolonged reduction in oil and natural gas
prices, however, will depress the level of exploration, development and
production activity and result in a corresponding decline in the demand for the
Company's services and, therefore, have a material adverse effect on the
Company's results of operation and financial position.

     In addition to adverse effects that future declines in demand could have on
the Company, ongoing movement or reactivation of offshore rigs or new
construction of rigs could adversely affect dayrates and utilization levels,
even in an environment of stronger oil and natural gas prices and increased
drilling activity. Moreover, increases in worldwide drilling demand since
mid-1995 and the attendant increase in the number of rigs operating has resulted
in a shortage of qualified rig personnel in the industry. If the Company is
unable to attract and retain sufficient qualified personnel, its ability to move
rigs and to put stacked and newly acquired rigs into service will be limited.
Further, labor shortages could result in wage increases, which could, without
offsetting increases in revenues, reduce the Company's operating margins.

RISK OF UPGRADE AND REFURBISHMENT PROJECTS

     The Company has committed to substantial upgrade and refurbishment capital
expenditures and expects to pursue additional upgrade opportunities in the
future. Such projects are subject to the risks of delay or cost overruns
inherent in any large construction project, including shortages of materials or
skilled labor, unforeseen engineering problems, work stoppages, weather
interference, unanticipated cost increases, and inability to obtain any of the
requisite permits or approvals. In particular, there is a current shortage of
certain types of drilling equipment that could delay and increase the cost of
certain upgrades. The Company attempts to minimize the potential for cost
overruns and delays through detailed real-time tracking of costs associated with
mobilization, construction and ongoing operations of its rigs. Significant cost
overruns or delays would adversely affect the Company's financial condition and
results of operations. Significant

                                       8
<PAGE>
delays could also adversely affect the Company's marketing plans for its
drilling units and could jeopardize the long-term contracts under which the
Company plans to operate certain drilling units.

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, cratering, 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 substantial 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. Moreover,
such insurance is subject to substantial deductibles and provides for premium
adjustments based on claims. Management believes that the Company has a good
claims record. 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 Company does not maintain
business interruption insurance, and damage to its equipment, even if such
damage is covered by insurance, may result in a loss of revenues against which
the Company is not insured. The occurrence of a significant event against which
the Company is not fully insured could have a material adverse effect on the
Company's results of operations or financial position.

FOREIGN OPERATIONS

     The operations of the Company are conducted primarily in foreign waters.
For the fiscal years ended 1994, 1995 and 1996, the Company's revenues
attributable to foreign operations were 92%, 93% and 92%, respectively, of total
revenues. The Company's foreign operations are subject to political, economic
and other uncertainties not encountered by purely domestic drilling contractors,
including the risk of expropriation of its equipment, expropriation of a
customer's property or drilling rights, foreign and domestic monetary policies,
repudiation of contracts, foreign exchange restrictions, foreign taxation,
adverse tax policies, general hazards associated with foreign sovereignty over
certain areas in which the Company operates, fluctuations in foreign economies,
United States regulation of direct foreign investment or additional taxation of
foreign income, boycotts and embargoes. 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. 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

     Typically, non-U.S. operations incur an effective tax rate higher than the
United States corporate statutory tax rate due to higher foreign tax rates in
certain jurisdictions or less than full creditability of foreign taxes paid.
While the Company's overall effective tax rate has recently been lower than the
U.S. tax rate because of net operating losses and other factors, the overall
effective tax rate may in the future be higher than the maximum United States
corporate statutory tax rate.

GOVERNMENT REGULATIONS

     The Company's business is affected by domestic and international political
developments and by federal, state, local and foreign laws and regulations that
may relate directly or indirectly to the oil and gas industry. The adoption of
laws and regulations curtailing exploration and development drilling for oil and
gas for economic, environmental and other policy reasons adversely affects the
Company's operations by limiting available drilling opportunities. Additionally,
laws relating to natural gas exploration and equipping and operating offshore
vessels may add to the cost of operating offshore drilling equipment.

                                       9
<PAGE>
ENVIRONMENTAL MATTERS

     The Company's operations are subject to federal, state, local and foreign
laws and regulations controlling the discharge of materials into the environment
or otherwise relating to the protection of the environment. Such laws and
regulations could impose significant liability on the Company for damages,
clean-up costs and penalties in the event of the occurrence of oil spills or
similar discharges of pollutants into the environment in the course of the
Company's operations. To date, such laws and regulations have not had a material
adverse effect on the Company's results of operations, nor has the Company
experienced an accident which has exposed it to material liability for
discharges of pollutants into the environment.

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, and there continues to
be competition in securing available drilling contracts. 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. In addition, there are a number of inactive
rigs that are being or could be reactivated and upgraded. Such reactivation, new
rig construction or a decrease in drilling activity in any major market could
depress dayrates and adversely affect utilization of the Company's rigs, even in
an environment of stronger oil and natural gas prices.

CONCENTRATION OF CUSTOMERS

     During fiscal 1996, the Company performed operations for ten major
customers. Esso Australia Limited/Esso Production Malaysia, Inc.,
Carigali-Triton Operating Sdn. Bhd. and Mobil Equatorial Guinea Inc. accounted
for 32%, 14% and 11%, respectively, of fiscal 1996 revenues. Although the
Company believes its customer relationships are strong, the loss of any
significant customer or a decrease in the drilling programs of significant
customers in the areas where they employ the Company could have a material
adverse effect on the Company's results of operations.

AVAILABILITY OF QUALIFIED RIG PERSONNEL

     Increases in worldwide drilling demand during the past two years and the
corresponding increase in the number of rigs working has resulted in a shortage
of qualified rig personnel in the industry. To date, the Company has not
experienced significant problems with personnel in its areas of operation,
however, if the Company is unable to continue to attract and retain sufficient
qualified personnel, its operations could be adversely affected and its ability
to put newly acquired rigs to work could be restricted. A shortage of personnel
could also result in wage increases which could, without offsetting increases in
revenues, affect the Company's profitability.

CONTROL BY CERTAIN STOCKHOLDERS

     Helmerich & Payne Inc. and its wholly-owned subsidiary, Helmerich & Payne
International Drilling Company (collectively "H&P"), beneficially own
approximately 23.8% of the outstanding shares of Common Stock of the Company. As
a result, H&P has the ability to influence the election of the Company's
directors, which may be conducted on a cumulative voting basis pursuant to the
Company's charter, and the outcome of other matters requiring a stockholder
vote. Three of the Company's six directors are affiliated with H&P. H&P has
expressed its intention to purchase 25% of the shares offered hereby (excluding
the over-allotment option).

<PAGE>
                                USE OF PROCEEDS
   
     The net proceeds to be received by the Company from the Offering, after
deducting underwriting discounts and commissions and estimated expenses, are
estimated to be approximately $87.8 million ($100.9 million if the Underwriters'
over-allotment option is exercised in full), assuming a public offering price of
$61 1/4 per share. Such net proceeds will be used (i) to satisfy contractual
commitments to upgrade and relocate the ATWOOD HUNTER at a cost of approximately
$45 million, before realization of $10 million in mobilization revenues, (ii) to
satisfy contractual commitments to refurbish and upgrade the ATWOOD SOUTHERN
CROSS at a cost of approximately $25 million, (iii) to repay all of the
Company's bank debt, which has an outstanding balance of $22.3 million as of
February 4, 1997, and (iv) for general corporate purposes.
    
     One of the Company's bank credit facilities has an outstanding balance of
approximately $17.3 million, bears interest at a floating rate (approximately 7%
per annum at December 31, 1996), and matures in March 1998. The Company's
remaining $5 million outstanding bank debt is borrowed on a month-to-month basis
and currently bears interest at 6.2%. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Liquidity and Capital
Resources."

     Pending its use of proceeds, the Company will invest in short-term interest
bearing securities. If additional rig upgrade opportunities arise prior to
closing, the Company may reevaluate its decision to repay bank debt with
proceeds of the Offering.

    on sale of investments, and minority interest in loss of partnerships) is
    frequently used by securities analysts and is presented here to provide
    additional information about the Company's operations. EBITDA should not be
    considered as an alternative to net income as an indication of the Company's

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OUTLOOK

     The current worldwide fleet utilization for mobile offshore drilling units
is approximately 92% compared to approximately 86% a year ago. Activity in the
offshore contract drilling industry is strong in virtually all worldwide market
areas, especially for mobile rigs that can operate in deeper water. The improved
market trends are particularly evident in the escalation of dayrates seen in
1996 and in the increase in equipment upgrade projects.

     The Company's active fleet utilization was 100% for fiscal 1996 and was in
excess of 99% for each of the past three fiscal years. During the second half of
fiscal 1996, the Company realized higher dayrates on the ATWOOD FALCON, ATWOOD
HUNTER, ATWOOD EAGLE and the RICHMOND. The Company entered into a contract to
operate the ATWOOD HUNTER in deep water in the Gulf of Mexico, commencing in
mid-1997, at a significant increase in dayrate and operating margins. The
Company was also awarded a contract on the ATWOOD SOUTHERN CROSS for operations
in Australia following a substantial refurbishment and upgrade of the rig. In
addition, a new contract for the ATWOOD FALCON contains an option which, if
exercised, would provide for a three-year deep water drilling program in the
Philippines' South China Sea following a rig upgrade. Based upon firm contract
commitments for its active fleet, management expects that the Company will
maintain a high level of equipment utilization during fiscal 1997.

RESULTS OF OPERATIONS

FIRST QUARTER FISCAL 1996 VERSUS FIRST QUARTER FISCAL 1997

     During the first quarter of fiscal 1997, the Company continued to maintain
100% utilization of its drilling equipment. Contract revenues, earnings before
interest expense, taxes and depreciation and net income for the three months
ended December 31, 1996 increased 22%, 85% and 492%, respectively, compared to
the three months ended December 31, 1995. This improvement in operating results
reflects the impact of dayrate increases on several of the Company's mobile rigs
which occurred during the fourth quarter of fiscal 1996 and the first quarter of
fiscal 1997, coupled with the commencement of dayrate revenues in January 1996
on RIG-200. A comparative analysis of contract revenues is as follows:

</TABLE>

     The increase in revenues for the ATWOOD FALCON was due to an increase of
approximately 60% in the contract dayrates during the quarter ended September
30, 1996. The increase in revenues for the ATWOOD HUNTER was also due to higher
average dayrates, which increased 35% from the first quarter of fiscal 1996 to
the first quarter of fiscal 1997. The ATWOOD HUNTER completed its work in
Malaysia

                                       14
<PAGE>
in December 1996 and was mobilized to Singapore to undergo a substantial
upgrade. No income or expenses associated with the ATWOOD HUNTER will be
recognized during the second and third quarters of fiscal 1997 while the upgrade
is in progress. During fiscal 1996, the ATWOOD EAGLE was relocated from
Australia to Equatorial Guinea with an approximate 25% increase in contract
dayrate. The delivery of RIG-200 to Australia was completed in November 1996.
RIG-200 was installed on the offshore platform in November and December 1996,
and commenced drilling operations in January 1997. Commencing in January 1997,
net realized mobilization income (approximately $3 million) will be amortized
over the estimated contract term of five years. Relatively long-term, stable
contracts for the SEAHAWK and VICKSBURG continue to provide consistency to these
operations. During the first quarter of fiscal 1997, RIG-19 was relocated to a
new platform, which caused revenues to decline as no revenues or expenses were
recognized during the relocation period. The Company's only current United
States operation, the RICHMOND, continues to experience an increase in dayrate
revenues. The increase in NORTH RANKIN "A' revenues was due to an increase in
labor services provided to the rig.

     Contract drilling and management costs were $12.7 million for the first
quarter of fiscal 1997 compared to $13.0 million for the first quarter of fiscal
1996. This decline in operating costs was primarily attributable to lower
operating costs for RIG-19 and the ATWOOD EAGLE. An analysis of contract
drilling and management costs by rig is as follows:

</TABLE>

     The increases in operating costs for the ATWOOD HUNTER, SEAHAWK, RICHMOND,
GOODWYN "A' and NORTH RANKIN "A' were due primarily to increases in payroll
related costs. The reduction in operating costs for the ATWOOD EAGLE was
attributable to the rig working in Equatorial Guinea where labor costs are lower
than in Australia. The relocation of RIG-19 to a new platform during the first
quarter of fiscal 1997 accounted for its reduction in costs, as no revenues or
costs are recognized during the relocation period.

     The reduction in depreciation expense for the ATWOOD HUNTER was a result of
moving the rig into the shipyard in December 1996 for upgrade. While undergoing
upgrade (estimated to take six to seven months), no depreciation expense is
recognized on the rig. Depreciation of RIG-200 will commence with the start-up
of its drilling operations in January 1997.

     General and administrative expense increased 43% in the first quarter of
fiscal 1997 compared to the first quarter of fiscal 1996. This increase was
attributable to increases in payroll related costs and professional fees. As a
result of a reduction in outstanding long-term debt, interest expense declined.
Due to an increase in profitability and a reduction in tax attributes, current
United States taxation is expected to be higher in fiscal 1997 compared to
fiscal 1996, which accounted for the increase in the provision for income taxes.

FISCAL YEAR 1995 VERSUS FISCAL YEAR 1996

     Contract revenues in fiscal 1996 increased 10% to $79.5 million from $72.2
million in fiscal 1995. This increase was primarily attributable to commencement
of contract revenues from RIG-200 in addition to general dayrate increases on
the fleet. An analysis of contract revenues by rig for fiscal years 1995 and
1996 is as follows:

     The increase in revenues for the ATWOOD FALCON was due to an increase of
approximately 60% in the contract dayrate during the fourth quarter of fiscal
1996. The increase in revenues for the ATWOOD HUNTER was also due to higher
dayrates in fiscal 1996 compared to fiscal 1995. During April and May

                                       16
<PAGE>
1996, the ATWOOD EAGLE was relocated from the territorial waters of Australia to
the territorial waters of Equatorial Guinea with an approximate 25% increase in
contract dayrate. The Company received dayrate revenues from RIG-200 during the
period January 1996 through September 1996 while awaiting instructions for
shipment to Australia. The rig was delivered to Australia in November 1996 and
earns a holding dayrate or mobilization fee pending the anticipated commencement
of drilling operations in January 1997. Relatively long-term, stable contracts
for the SEAHAWK, VICKSBURG and RIG-19 continue to provide consistency to these
operations. The $1.1 million increase in RIG-19 revenues was due to an increase
in the dayrates during fiscal 1996. As a result of improved market conditions,
the RICHMOND, located in the United States Gulf of Mexico, also experienced an
increase in dayrate revenues during fiscal 1996.

     In contrast to a 10% increase in contract revenues, contract drilling and
management costs increased only 1% in fiscal 1996 compared to fiscal 1995. An
analysis of contract drilling and management costs by rig is as follows:

     The increases in operating costs for the ATWOOD FALCON, SEAHAWK and
RICHMOND were due to increases in general maintenance and payroll related costs.
The reduction in the ATWOOD EAGLE's costs was attributable to the rig being
relocated from Australia to Equatorial Guinea where operating costs are lower,
primarily due to reductions in local labor costs, and to the rig incurring costs
in fiscal 1995 associated with certain required surveys and repairs that were
not required in fiscal 1996. The increase in operating costs of RIG-19 was
primarily due to higher payroll related costs as a result of certain labor union
awards in Australia. The increase in operating costs of the GOODWYN "A' was also
attributable to higher labor costs in Australia.

     General and administrative expenses increased 14% in fiscal 1996 compared
to fiscal 1995. This increase was attributable to increases in payroll related
costs and professional fees. Investment income in fiscal years 1995 and 1996 of
$2.8 million and $2.5 million, respectively, virtually offset interest expense
for both years. In fiscal 1996, the Company sold its remaining 32,000 shares of
Mobil Corporation common stock at a realized gain of $2.8 million. Foreign tax
expense increased from $1.6 million in fiscal 1995 to $2.6 million in fiscal
1996 and domestic taxes increased from $300,000 in fiscal 1995 to $1.9 million
in fiscal 1996, which accounted for the increase in the provision for income
taxes.

FISCAL YEAR 1994 VERSUS FISCAL YEAR 1995

     Contract revenues in fiscal 1995 increased 9% to $72.2 million from $66.0
million in fiscal 1994. This increase was primarily attributable to increases in
revenues from the ATWOOD EAGLE and GOODWYN "A' of $3.1 million and $5.1 million,
respectively, offset somewhat by a $1.7 million decrease in revenues from NORTH
RANKIN "A'. An analysis of contract revenues by rig for fiscal years 1994 and

     The ATWOOD FALCON started fiscal 1995 working in Korea; however, in the
second quarter of the year, the rig was relocated to China, and during the last
quarter, it was relocated to the Malaysia/Thailand Joint Development Area. The
reduced revenues during the relocation periods accounted for the small decrease
in revenues with respect to the ATWOOD FALCON. The ATWOOD HUNTER has worked
continuously in Malaysia for the same customer since April 1993. During the
first quarter of fiscal 1994, the

                                       18
<PAGE>
ATWOOD EAGLE was relocated from Malaysia to the Australia/Indonesia Zone of
Cooperation, where the rig worked continuously until it was moved in September
1995 to sheltered water to undergo certain planned surveys and repairs. Even
with four more days of idle time in fiscal 1995, revenues for the ATWOOD EAGLE
were higher due to the rig working at a higher dayrate level in fiscal 1995
compared to fiscal 1994. Relatively long-term, stable contracts for the SEAHAWK,
VICKSBURG and RIG-19 continued to provide consistency to these operations during
fiscal 1995. The $500,000 increase in VICKSBURG revenues was due to an increase
in the dayrate commencing in February 1995. In August 1995, the RICHMOND was
moved to sheltered water to undergo certain planned surveys and repairs. This
required downtime accounted for the RICHMOND's decrease in revenues. During
fiscal 1994, the Company received a standby fee related to GOODWYN "A' while
awaiting commencement of drilling operations, which occurred during the first
quarter of fiscal 1995. The Company received substantially higher revenues from
GOODWYN "A' during drilling operations, resulting in an increase of revenues in
fiscal 1995 over fiscal 1994. The reduction in revenues from NORTH RANKIN "A'
was due to the Company providing less labor services to this operation in fiscal
1995.

     Contract drilling and management costs increased 15% from $44.3 million in
fiscal 1994 to $50.8 million in fiscal 1995. This increase was primarily
attributable to increased costs on the ATWOOD EAGLE and GOODWYN "A'. An analysis

     The reduction in ATWOOD FALCON costs in fiscal 1995 was due to the rig
working a portion of fiscal 1994 in Australia where costs are significantly
higher than in most countries of Southeast Asia. The ATWOOD HUNTER's costs have
been relatively unchanged due to its stable contract status. Cost increases for
the ATWOOD EAGLE were attributed to the rig working the entire year in the
Australia/Indonesia Zone of Cooperation where costs are higher than in Malaysia
and to costs incurred in performing certain required surveys and repairs during
the last two weeks of September 1995. In fiscal 1994, the VICKSBURG and RIG-19
received some personnel tax refunds which accounted for the increase in costs as
no such refunds were received in fiscal 1995. Like the ATWOOD EAGLE, the
RICHMOND had to undergo certain surveys and repairs in August 1995 which
accounted for its operating cost increases. The increase in GOODWYN "A'
operating costs related directly to the commencement of drilling operations.
Even though the Company does not own this facility, the Company does provide
personnel and other operating support services. The decline in NORTH RANKIN "A'
costs was due to a reduction in personnel services provided to this operation.

     The Company acquired the remaining 50% interest in the ATWOOD FALCON,
ATWOOD HUNTER and ATWOOD EAGLE, effective as of December 31, 1994, on the basis
that these rigs will remain long-term productive assets. Effective January 1,
1995, management increased its estimated depreciable lives on these rigs by an
additional five years. The effect of the change in depreciable lives was a $2.7
million reduction in depreciation for the last nine months of fiscal 1995
compared to fiscal 1994 and a corresponding increase in net income in fiscal
year 1995 of $1.8 million or $.27 per share. An analysis of depreciation expense

     At the time the Company acquired the remaining interest in the ATWOOD
FALCON, ATWOOD HUNTER and ATWOOD EAGLE, these rigs were incurring net losses,
50% of which were allocated to the limited partner. As a result of this
acquisition, for the last nine months of fiscal year 1995, there was no
accounting for a minority interest.

     In fiscal 1995, the Company sold 33,000 shares of Mobil Corporation common
stock at a realized gain of $2.4 million. Investment income of $2.8 million for
each of the fiscal years 1994 and 1995 virtually offset interest expense in each
year. Foreign tax expense increased from approximately $500,000 in fiscal 1994
to $1.6 million in fiscal 1995, which accounted for substantially all of the
increase in the provision for income taxes.

LIQUIDITY AND CAPITAL RESOURCES

     During fiscal 1996, operating cash flows (before changes in working capital
and other assets and liabilities) increased 36% from $14.9 million in fiscal
1995 to $20.3 million, and operating cash flows increased 89% from $3.4 million
in the first quarter of fiscal 1996 to $6.5 million in the first quarter of
fiscal 1997. During fiscal 1996, the Company invested approximately $3 million
in completing the construction of RIG-200, purchased approximately $7 million in
capital equipment for the ATWOOD HUNTER, ATWOOD SOUTHERN CROSS and other rigs,
repaid approximately $6 million of bank debt and reduced accounts payable by
approximately $4 million. For the three months ended December 31, 1996, the
Company purchased approximately $6 million of additional capital equipment for
the ATWOOD HUNTER and other rigs and reduced bank debt by approximately $4
million.

     The Company has a contractual commitment to upgrade the ATWOOD HUNTER to
drill in 3,500 feet of water and relocate the rig from Southeast Asia to the
United States Gulf of Mexico in mid-1997 at an aggregate cost of approximately
$45 million, offset in part by a $10 million mobilization fee. The Company also
has a contractual commitment to substantially refurbish and upgrade the ATWOOD
SOUTHERN CROSS at a total cost of approximately $25 million in order to achieve
up to 2,000 feet water depth drilling capability. In addition, if an option is
exercised pursuant to a contract for the ATWOOD FALCON, the Company will be
required to upgrade the rig to drill in 3,500 feet of water at an estimated cost
of approximately $50 million.

                                       20
<PAGE>
     At December 31, 1996, the Company continued to have approximately $22.6
million invested in United States treasury bonds with maturities in the years
2000 and 2001. The Company's portfolio of accounts receivable is comprised of
major international corporate entities with stable payment experiences. The
Company continues to experience no difficulties in receivable collections.

     At December 31, 1996, the Company had outstanding bank debt of $29.3
million, all of which was borrowed by a subsidiary of the Company that owns the
ATWOOD HUNTER and the ATWOOD EAGLE. The debt is secured by preferred mortgages
on the ATWOOD HUNTER and ATWOOD EAGLE, and the loan documents restrict the
amount of capital expenditures that can be incurred in any given year on these
rigs. The estimated capital expenditures to be incurred in fiscal 1997 to
upgrade the ATWOOD HUNTER to enable the rig to perform under its three year
contract with British-Borneo Petroleum Inc. will significantly exceed the annual
limit. On February 3, 1997, the bank group agreed to waive the annual capital
expenditures limit for 1997, and the Company reduced the outstanding loan
balance through a $10 million prepayment and agreed to guaranty $3 million of
the outstanding balance. The Company estimates that excess cash flows during the
1997 calendar year will require $9 million in principal payments, in addition to
regular payments of $750,000 per quarter. The remaining balance of the facility
is due in March 1998.

     The Company obtained an additional $30 million short-term line of credit
with a bank that is secured by the pledge of all the Company's United States
treasury bonds. The Company borrowed $5 million under this facility in February
1997 to finance a portion of the prepayment to the bank group. Additional
borrowings under this facility may be used to fund principal payments to the
bank group, and to fund equipment upgrades or for general corporate purposes.

     The Company believes that cash on hand, borrowings under its new credit
facility and the proceeds of the Offering will be sufficient to fund its planned
rig upgrades and other capital expenditures during 1997. The Company would
expect to finance additional upgrade expenditures through a combination of
operating cash flow, equity or debt financings or a sale of investment
securities. The Company continues to periodically review and adjust its planned
capital expenditures in light of current market conditions.

                                    BUSINESS

THE COMPANY

     The Company provides offshore contract drilling services to the oil and gas
industry. The Company's diversified rig fleet consists of eight wholly-owned
rigs, including three third-generation semisubmersibles, one second-generation
semisubmersible, one jack-up, one second-generation semisubmersible
tender-assist vessel, one submersible and one modular self-contained platform
rig, and a fifty percent interest in a newly-constructed platform rig. The
Company's fleet is currently operating in Australia, Southeast Asia, Equatorial
Guinea and the United States. The Company also provides management, labor and
supervisory services pursuant to contracts for two operator-owned drilling and
production platforms.

     In fiscal 1996, the Company maintained 100% utilization of its drilling
rigs placed in service, and the Company maintained a utilization rate in excess
of 99% for each of the past three fiscal years. Improved financial results for
the Company in fiscal 1996 reflect continuing high rig utilization coupled with
significant dayrate increases for several of the Company's rigs, which were
achieved primarily during the second half of 1996. The Company has recently been
awarded two substantial rig upgrade contracts, and based upon contract
commitments, the Company expects to maintain a high level of utilization of its
remaining rigs during fiscal 1997.

     Financial results for the first quarter of fiscal 1997 reflect the impact
of significant dayrate increases realized for several of the Company's rigs.
Contract revenues and earnings before interest expense, taxes and depreciation
for the three months ended December 31, 1996 increased 22% and 85%,
respectively, compared to the three months ended December 31, 1995.

MARKET OVERVIEW

     During the last two years, offshore drilling activity has substantially
increased, raising the utilization of the worldwide offshore rig fleet to 92% as
of December 31, 1996, from 82% as of the beginning of 1995. The increase in
activity has been particularly strong in the semisubmersible market, in which
utilization has increased from 79% at the beginning of 1995 to 94% as of
December 31, 1996. The recent levels of offshore rig utilization represent the
highest levels in more than 10 years, driven in part by technological advances
in areas such as subsea completions, floating production systems, horizontal
drilling and 3-D seismic which have led to increased demand for drilling rigs
with deeper water capabilities. During this period, the Company has achieved
significant dayrate increases and secured longer terms for its contracts. The
Company has secured two substantial rig upgrade contracts, and the Company
executed a contract in January 1997 which, if an option is exercised, will
result in a third substantial rig upgrade. The Company is actively pursuing
additional rig upgrade opportunities.

BUSINESS STRATEGY

     The Company seeks to enhance shareholder value and maximize profitability,
rig utilization and dayrate margins through (i) upgrading the performance
capabilities of its rig fleet, (ii) operating a diversified rig fleet with an
international focus, (iii) seeking growth opportunities through rig acquisitions
and new rig construction, (iv) maximizing flexibility through conservative
financial management, and (v) maintaining a quality reputation for customer
service and safety.

     RIG FLEET UPGRADES -- The Company is capitalizing on opportunities to
enhance its rig fleet to take advantage of increased market dayrates for rigs
with deeper water drilling capabilities. The Company believes it can generate
significantly higher dayrates with increased operating margins by upgrading the
water depth drilling capabilities and deckload capacities of its rigs, thereby
earning a higher rate of return on investment.

     The ATWOOD HUNTER is currently undergoing a substantial upgrade at a cost
of approximately $45 million. This upgrade will increase the deckload capacity
of the rig and enable the rig to operate in 3,500 feet of water. The upgrade is
undertaken in connection with a three-year contract for drilling operations in
the Gulf of Mexico, under which the ATWOOD HUNTER is expected to commence
drilling operations in the fourth quarter of fiscal 1997. The contract provides
for a $10 million mobilization fee which offsets a portion of the Company's
upgrade and mobilization costs.

                                       22
<PAGE>
     In January 1997, the Company was awarded a 175-day drilling contract for
the ATWOOD SOUTHERN CROSS, which has been stacked in Australia since it was
acquired for $1.5 million in fiscal 1994. The rig should be mobilized to
Singapore in March 1997 to undergo substantial refurbishment and upgrade at a
total cost of approximately $25 million in order to achieve up to 2,000 feet
water depth drilling capability. Upon completion of the refurbishment and
upgrade, the rig will commence drilling operations in Australia in late fiscal
1997 or early fiscal 1998.

     Following completion of the ATWOOD FALCON's current contract (estimated
November 1997), the rig will be mobilized to the Philippines to commence
drilling under a contract which provides for drilling of two initial wells
(estimated 90 days duration), with an option (which may be exercised on or
before June 30, 1997) for three years of drilling operations in up to 3,500 feet
of water in the Philippines' South China Sea. In the event the option is
exercised, the rig will be transported to a shipyard following completion of the
initial two well program to undergo an upgrade at a cost of approximately $50
million, which would be partially offset by a $10 million mobilization fee.
Management estimates that the upgrade and mobilization will take six to seven
months to complete.

     The ATWOOD EAGLE is a candidate for similar upgrade opportunities in late
fiscal 1998 or thereafter. Potential customer requirements and the renewal of
option terms on the ATWOOD EAGLE will determine the extent of and timing for any
such upgrade.

     The VICKSBURG, a 300 foot water depth rated jack-up rig currently working
in production mode in Australia, is also a candidate for upgrade in fiscal 1998.
Depending on contract opportunities and potential customer requirements, the
Company's options upon completion of the current contract, which could extend to
January 1998, include returning the rig to drilling mode at a cost of
approximately $3 million or undertaking a substantial upgrade at a cost ranging
from $10 to $30 million, depending on the extent of the upgrade. The Company
estimates that expenditures of approximately $30 million would enable the rig to
be upgraded to provide for increased leg lengths, cantilever extended reach
drilling with a top drive, increased deckload capacity and other enhanced
drilling capabilities.

     DIVERSIFIED OPERATIONS AND INTERNATIONAL FOCUS -- The Company's fleet
consists of six mobile drilling rigs, including four semisubmersibles, one
jack-up and one submersible, as well as two platform rigs and a semisubmersible
tender-assist vessel. The Company also provides management, labor and
supervisory services pursuant to contracts for two operator-owned drilling and
production platforms. The Company has been active in the Australian and
Southeast Asian markets since 1970, and the Company's international operations
in Australia, Southeast Asia and Equatorial Guinea accounted for over 92% of its
fiscal 1996 revenues. Offshore drilling activities in these markets continue to
increase as advances in technology (including subsea completions, floating
production systems, horizontal drilling and 3-D seismic), growth in market
demand for oil and gas, and expansion of local market transportation and
processing infrastructures improve the economics of offshore exploration and
production.

     GROWTH OPPORTUNITIES -- The Company has historically grown its fleet
through both rig acquisitions and new rig construction. In fiscal 1990, the
Company significantly enhanced the size and quality of its fleet by acquiring a
50% interest in three third-generation semisubmersible rigs, the ATWOOD FALCON,
ATWOOD EAGLE and ATWOOD HUNTER. In fiscal 1995, the Company acquired the
remaining 50% interest in these three rigs. In fiscal 1994, the Company expanded
its fleet by acquiring a second-generation semisubmersible rig, the ATWOOD
SOUTHERN CROSS. The Company participated in the design and fabrication of a
new-generation platform rig, RIG-200, through a 50/50 joint venture with a
subsidiary of Helmerich & Payne, Inc. RIG-200 commenced operations in January
1997 pursuant to a contract with Esso Australia Limited for drilling operations
in the West Tuna field offshore Australia. The Company continues to seek
opportunities to invest in rig acquisitions and new rig construction.

     CONSERVATIVE FINANCIAL MANAGEMENT -- The Company maximizes its flexibility
to pursue upgrade and other growth opportunities by limiting its debt position
as well as maximizing its margins and internal cash flow through strict cost
control. The Company's management systems include detailed real-time tracking of
costs associated with the mobilization and ongoing operations of its rigs,
thereby allowing the Company to maximize profitability under the terms of its
contracts in all geographic areas of operation. After the Offering, the Company
will have less than $2 million of outstanding debt.

                                       23
<PAGE>
     QUALITY REPUTATION -- The Company is an experienced, safety-conscious
contract driller and has built long-term customer relationships with several of
the largest and most active operators of offshore oil and gas properties,
including U.S. and foreign integrated and independent oil and gas companies.
Over the last two fiscal years, the Company's high-quality customer base has
included Esso Australia Limited and Esso Production Malaysia, Inc. (33% of total
revenues over the period), BHP Petroleum Pty. Ltd. (11%), Carigali-Triton
Operating Company Sdn. Bhd. (10%), Woodside Offshore Petroleum Pty. Ltd., an
Australian company affiliated with Shell, British Petroleum, BHP Petroleum,
Chevron and Mitsubishi (10%), Mobil Equatorial Guinea Inc. (6%), and Shell
Offshore, Inc. (5%). The Company has received extensive customer recognition for
the safety of its contract drilling operations and completed fiscal 1996 without
experiencing a lost-time accident.

OFFSHORE DRILLING EQUIPMENT

     The Company's diversified fleet of owned or operated drilling rigs
currently consists of four semisubmersibles, one jack-up, one submersible 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 applications of the 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.

     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 on these
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 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.

     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
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.

                                       24

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 or years 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. As a result of
improved market conditions, contracts with a term of one year or longer are now
being awarded in certain markets, including in the U.S. Gulf of Mexico, where
the ATWOOD HUNTER will commence operations in mid-1997 under a three-year
contract. However, there is no guarantee that the current trend of awarding
long-term contracts will continue.

     The rate of compensation specified in each contract depends on the nature
of the operation to be performed, the duration of the work, equipment and
services provided, the 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. The Company does not provide turnkey contract
drilling services. 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 profit. An
oversupply of drilling rigs in any market area can adversely affect the
Company's ability to employ its drilling vessels. In fiscal 1996, the Company
maintained 100% utilization of its drilling equipment placed in service. Based
upon current contract commitments, the Company should maintain a high level of
equipment utilization in fiscal 1997; however, there is no guarantee that the
Company will not experience some equipment idle time in fiscal 1997.

     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. As a result of improved market conditions, in recent times,
the Company has received full recovery of relocation costs; however, there is no
guarantee that this trend will continue.

     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.

ENVIRONMENTAL MATTERS

     The Company's operations are subject to federal, state, local and foreign
laws and regulations controlling the discharge of materials into the environment
or otherwise relating to the protection of the environment. Such laws and
regulations could impose significant liability on the Company for damages,
clean-up costs and penalties in the event of the occurrence of oil spills or
similar discharges of pollutants into the environment in the course of the
Company's operations. To date, such laws and regulations have not had a material
adverse effect on the Company's results of operations, nor has the Company
experienced an accident which has exposed it to material liability for
discharges of pollutants into the environment.

                                       25
<PAGE>
     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 1996, the Company performed operations for 10 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 1996 revenues. Esso Australia Limited/Esso
Production Malaysia, Inc., Carigali-Triton Operating Company Sdn Bhd. and Mobil
Equatorial Guinea Inc. accounted for 32%, 14% and 11%, respectively, of fiscal
year 1996 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 although the Company believes its customer relationships are
strong, the loss of any significant customer or a decrease in the drilling
programs of significant customers in the areas where they employ the Company may
adversely affect the Company's results of operations.

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, and there continues to
be competition in securing available drilling contracts. 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. In addition, there are a number of inactive
rigs that are being or could be reactivated and upgraded. Such reactivation, new
rig construction or a decrease in drilling activity in any major market could
depress dayrates and adversely affect utilization of the Company's rigs, even in
an environment of stronger oil and natural gas prices.

     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 rig availability, 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. Demand for drilling equipment is also dependent on the exploration and
development programs of oil and natural gas companies, which are in turn
influenced by the financial condition of such companies, by general economic
conditions, by prices of oil and natural gas, and from time to time by political
considerations and policies.

EMPLOYEES

     The Company currently employs approximately 650 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.

LEGAL PROCEEDINGS

     From time to time, claims are filed against the Company in the ordinary
course of business. In the opinion of management, no pending claims against the
Company are expected to have a material adverse effect on its financial position
or results of operations.

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

     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent and that the
Underwriters will be obligated to purchase all of the shares of Common Stock
offered hereby (other than those shares covered by the over-allotment option
described below) if any are purchased. The Underwriting Agreement provides that,
in the event of a default by an Underwriter, in certain circumstances the
purchase commitments of non-defaulting Underwriters may be increased or the
Underwriting Agreement may be terminated.

     The Company has granted to the Underwriters an option, expiring at the
close of business on the 30th day after the date of this Prospectus, to purchase
up to 225,000 additional shares at the initial public offering price less the
underwriting discounts and commissions, all as set forth on the cover page of
this Prospectus. Such option may be exercised only to cover over-allotments in
the sale of the shares of Common Stock. To the extent such option is exercised,
each Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional shares of Common
Stock as it was obligated to purchase pursuant to the Underwriting Agreement.

     The Company has been advised by the Representatives that the Underwriters
propose to offer the Shares to the public initially at the public offering price
set forth on the cover page of this Prospectus and, through the Representatives,
to certain dealers at such price less a concession of $       per share, and the
Underwriters and such dealers may allow a discount of $       per share on sales
to certain other dealers. After the initial public offering, the public offering
price and concession and discount to dealers may be changed by the
Representatives.

     In connection with this Offering, Credit Suisse First Boston Corporation
and certain of the Underwriters and selling group members (if any) and their
respective affiliates may engage in passive market making transactions in the
Common Stock on The Nasdaq Stock Market in accordance with Rule 10b-6A under the
Exchange Act during a period before commencement of offers or sales of the
Shares offered hereby. The passive market making transactions must comply with
applicable volume and price limits and be identified as such.

     The Company and H&P and each of the Company's directors and executive
officers have agreed that they will not offer, sell, contract to sell, announce
their intention to sell, pledge or otherwise dispose of, directly or indirectly,
or file with the Securities and Exchange Commission (the "Commission") a
registration statement under the Securities Act relating to, any shares of
Common Stock or securities convertible into or exchangeable or exercisable for
any shares of the Common Stock without the prior written consent of Credit
Suisse First Boston Corporation for a period of 120 days (with respect to the
Company and H&P) or 60 days (with respect to the Company's directors and
officers) after the date of this Prospectus, except in the case of the issuances
by the Company pursuant to the exercise of employee stock options outstanding on
the date hereof.

Stock are expected to be purchased by H&P from the Underwriters at a price equal
to the Price to Public and H&P set forth on the cover of this Prospectus. H&P
has indicated its intention to acquire such shares, subject to receipt and
review by H&P of a final Prospectus and conditioned upon a closing of the
Offering. No underwriting discounts and commissions are to be paid to the

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     The distribution of the Shares in Canada is being made only on a private
placement basis exempt from the requirement that the Company prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of Shares are effected. Accordingly, any resale of the Shares in Canada
must be made in accordance with applicable securities laws which will vary
depending on the relevant jurisdiction, and which may require resales to be made
in accordance with available statutory exemptions or pursuant to a discretionary
exemption granted by the applicable Canadian securities regulatory authority.
Purchasers are advised to seek legal advice prior to any resale of the Shares.

REPRESENTATIONS OF PURCHASERS

     Each purchaser of Shares in Canada who receives a purchase confirmation
will be deemed to represent to the Company and the dealer from whom such
purchase confirmation is received that (i) such purchaser is entitled under
applicable provincial securities laws to purchase such Shares without the
benefit of a prospectus qualified under such securities laws, (ii) where
required by law, that such purchaser is purchasing as principal and not as
agent, and (iii) such purchaser has reviewed the text above under "Resale
Restrictions".

RIGHTS OF ACTION AND ENFORCEMENT

     The securities being offered are those of a foreign issuer, and Ontario
purchasers will not receive the contractual right of action prescribed by
section 32 of the Regulation under the Securities Act (Ontario). As a result,
Ontario purchasers must rely on other remedies that may be available, including
common law rights of action for damages or rescission or rights of action under
the civil liability provisions of the U.S. federal securities laws.

     All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be possible
for Ontario purchasers to effect service of process within Canada upon the
issuer or such persons. All or a substantial portion of the assets of the issuer
and such persons may be located outside of Canada and, as a result, it may not
be possible to satisfy a judgment against the issuer or such persons in Canada
or to enforce a judgment obtained in Canadian courts against such issuer or
persons outside of Canada.

NOTICE TO BRITISH COLUMBIA RESIDENTS

     A purchaser of Shares to whom the Securities Act (British Columbia) applies
is advised that such purchaser is required to file with the British Columbia
Securities Commission a report within ten days of the sale of any Shares
acquired by such purchaser pursuant to this Offering. Such report must be in the
form attached to British Columbia Securities Commission Blanket Order BOR
#95/17, a copy of which may be obtained from the Company. Only one such report
must be filed in respect of Shares acquired on the same date and under the same
prospectus exemption.

                                 LEGAL MATTERS

     Certain legal matters in connection with the Common Stock being offered
hereby will be passed upon for the Company by Griggs & Harrison, P.C., Houston,
Texas. Certain legal matters relating to this Offering will be passed upon for
the Underwriters by Vinson & Elkins L.L.P., Houston, Texas.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Board of Directors of Atwood Oceanics, Inc.:

     We have audited the accompanying consolidated balance sheet of Atwood
Oceanics, Inc. (a Texas corporation) and subsidiaries as of September 30, 1995
and 1996, 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, 1996. 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, 1995 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
September 30, 1996, in conformity with generally accepted accounting principles.

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. 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, Equatorial Guinea, United
States and the Malaysian/Thailand Joint Development Area.

     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 natural 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 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.

NOTE 2 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

UNAUDITED INTERIM INFORMATION --

     The unaudited interim financial statements as of December 31, 1996 and for
each of the three month periods ended December 31, 1995 and 1996, included
herein, have been prepared by the Company, pursuant to the rules and regulations
of the Securities and Exchange Commission for interim financial reporting.
Accordingly, these financial statements and related information have been
prepared without audit, and certain information and note disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted, although management
believes that the note disclosures are adequate to make the information not
misleading. In the opinion of the Company's management, the unaudited interim
financial statements reflect all adjustments (consisting of normal recurring
adjustments) considered necessary for a fair presentation of the financial
position and results of operations of the Company for the periods presented. The
interim financial results may not be indicative of results that could be
expected for a full year.

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 50 percent undivided interest in RIG-200 is
accounted for using the proportionate consolidation method (See Note 4). Prior
to December 31, 1994, AOI owned a 50 percent interest in two Texas limited
partnerships, Atwood Deep Seas, Ltd. ("Deep Seas") and Atwood Falcon I, Ltd.
("Falcon Ltd."), the accounts of which were included in the Company's
consolidated financial statements. The limited partner's interest in the net
assets and loss of the two partnerships was reflected in the Company's financial
statements as "minority interest in partnerships."

<PAGE>
                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(See Note 4 -- "Acquisition of Interest in ATWOOD HUNTER, ATWOOD EAGLE and
ATWOOD FALCON"). 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 realized a foreign exchange gain of $240,000 in fiscal
year 1996, with foreign exchange losses of $155,000 and $417,000 incurred in
fiscal years 1995 and 1994, respectively.

DEPRECIATION, MAINTENANCE AND RETIREMENT POLICIES --

     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 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. There were no unamortized mobilization costs at September 30,
1995 or 1996.

     The Company defers the cost of scheduled drydocking and the cost is charged
to expense over the period to the next scheduled drydocking (normally 30
months). Deferred drydocking costs totaled $1,037,000 and $880,000 at September
30, 1995 and 1996, respectively.

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, 1996, deferred revenues totaling $3 million were included in other
deferred credits on the accompanying consolidated balance sheet. There were no
deferred revenues at September 30, 1995.

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 given the provisions of
enacted tax laws. For interim periods, the Company records income taxes using
the expected effective tax rate for the fiscal year.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

CASH AND CASH EQUIVALENTS --

     Cash and cash equivalents consist of cash in banks and certificates of
deposit which mature within three months of the date of purchase.

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, 1995 and 1996, investments in
available-for-sale securities are carried at fair value with the unrealized
holding gain or loss, net of deferred tax, included in shareholders' equity.

EARNINGS PER COMMON SHARE --

     Earnings per common share was computed by dividing net income by the
weighted average number of shares of common stock outstanding during each
period. The dilutive effect of stock options is immaterial.

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.
    
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.

RECLASSIFICATIONS --

     Certain reclassifications have been made to fiscal 1995 and fiscal 1994
financial statements to conform to the fiscal 1996 classifications.

NOTE 3 -- SECURITIES HELD FOR INVESTMENT
   
     At the beginning of fiscal year 1995, the Company adopted SFAS No. 115,
"Accounting for Certain Investments in Debt and Equity Securities," which had
an immaterial effect on the consolidated balance sheet and had no effect on
reported earnings. All of the Company's investments in equity securities are
classified as "available-for-sale" and accordingly, are reflected in the
September 30, 1995 and 1996 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, 1995
and 1996 Consolidated Balance Sheets at amortized cost.

NOTE 4 -- PROPERTY AND EQUIPMENT

RIG-200 --

     In August 1994, Atwood Oceanics West Tuna Pty. Ltd. ("West Tuna"), an
Australian Company owned 50 percent by the Company and 50 percent by Helmerich &
Payne, Inc. ("H&P")(current owner of 24 percent of the Company's outstanding
common stock), was awarded a term contract for the design, construction and
operation of a new generation platform rig. The Company and H&P entered into a
joint venture agreement to construct, install and operate the new rig. RIG-200
was constructed in the United States during calendar year 1995; however, due to
project delays in Australia unrelated to the Company's and H&P's activities,
West Tuna was advised to delay shipment of the rig to Australia until September
1996. Under terms of the contract, a holding dayrate has been received since
January 1, 1996. In addition, West Tuna received a $6 million partial prepayment
of a $10 million mobilization fee originally due upon commencement of operations
in Australia. The Company's $3 million portion of this prepayment is reflected
in "Other Deferred Credits" in the September 30, 1996 Consolidated Balance
Sheet.

     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 $11 million investment in RIG-200 at September 30, 1996, 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 year 1996
reflected in the Company's Consolidated Statement of Operations.

ACQUISITION OF INTEREST IN ATWOOD HUNTER, ATWOOD EAGLE AND
ATWOOD FALCON --

     Effective as of December 31, 1994, the Company acquired the remaining 50
percent interest in the ATWOOD HUNTER, ATWOOD EAGLE and the ATWOOD FALCON, at an
aggregate purchase price of approximately $36 million. This purchase price
consisted of approximately $13 million cash and the issuance or assumption of
debt totaling approximately $23 million. Combined with the Company's previous 50
percent ownership, the Company became the sole owner of these semisubmersible
rigs. The transaction was accounted for using the purchase method of accounting.

     When the Company acquired its initial interest in these rigs in fiscal
1990, their estimated useful lives for depreciation purposes were ten years. The
Company acquired the remaining 50 percent interest in these

                                      F-11
<PAGE>
                     ATWOOD OCEANICS, INC. AND SUBSIDIARIES
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
rigs on the basis that they will remain long-term productive assets; therefore,
effective January 1995 management increased the estimated useful lives of these
rigs by an additional five years. The effect of the change in depreciable lives
was a $2.7 million reduction in depreciation for the last nine months of fiscal
1995 compared to fiscal 1994 and a corresponding increase in net income of $1.8
million or $.27 per share.

ATWOOD HUNTER --

     In June 1996, the Company entered into a contract with British-Borneo
Petroleum Inc. for the use of the ATWOOD HUNTER on a firm two year plus a
one-year option Gulf of Mexico deep water drilling program commencing in
mid-1997. The option for the third year has subsequently been exercised. To
enable the ATWOOD HUNTER to perform this contract, the Company has committed to
upgrade equipment and relocate the rig from Southeast Asia to the United States
Gulf of Mexico at an aggregate cost of approximately $42 to $45 million. The
contract also requires the payment of a $10 million mobilization fee which will
offset some of the Company's costs. See Note 13.

ATWOOD SOUTHERN CROSS --

     The ATWOOD SOUTHERN CROSS, a second-generation semisubmersible which was
purchased by the Company for $1.5 million in fiscal 1994, remains idle in
Australia as the Company continues to pursue a future contract opportunity. The
Company believes upgrade expenditures of approximately $25 million will be
required to upgrade, refurbish and mobilize the rig to drill in water depths up
to 2,000 feet. The Company has incurred approximately $1.8 million in
capitalized costs to prepare the rig for various utilization alternatives and
has made commitments to purchase approximately $5 million of long lead-time
equipment for such an upgrade. The Company continues to actively market the rig
and remains optimistic that a profitable contract opportunity will be identified
for the rig. See Note 13.

ADOPTION OF FASB STATEMENT NO. 121 --
   
     In fiscal 1995, the Company adopted SFAS No. 121 "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed of."
Since adoption, SFAS No. 121 has had no impact on the Company's financial
statements.

     Required principal payments on the bank group debt are $750,000 per quarter
through December 31, 1997, with a final balloon payment of the remaining balance
payable in March 1998. The loan documents with the bank group require that
additional principal payments be made each quarter if quarterly cash flow
exceeds a defined level. Due to a significant improvement in Deep Seas'
operating results, Deep Seas made additional principal payments to the bank
group of approximately $1.1 million and $2.2 million in July 1996 and October
1996, respectively. The October 1996 payment is reflected in year-end estimated

maturities as of September 30, 1996. Estimated additional principal payments of
approximately $2 million will be required based on the estimated excess cash
flow of Deep Seas during the first quarter of fiscal year 1997 (included in
estimated current maturities of long-term debt as of September 30, 1996). The
bank group's collateral for the long-term notes consists principally of
preferred mortgages on the ATWOOD HUNTER and ATWOOD EAGLE. The loan documents
also prohibit the cash payment of management fees, profits and other cash
disbursements by Deep Seas prior to the time the notes are paid in full. There
is also an annual limit on the amount of capital expenditures that can be made
by Deep Seas. In fiscal 1995, Deep Seas obtained a waiver from the bank group
with respect to expenditures which exceeded the capital expenditures limit, and
it is anticipated that a similar waiver will be required in fiscal 1997 in
connection with the upgrade of the ATWOOD HUNTER. See Note 4 for a discussion of
the ATWOOD HUNTER upgrade. See Note 13 for a discussion of modifications to the
bank debt subsequent to September 30, 1996.

     A portion of the purchase price of the limited partner's interest in the
ATWOOD HUNTER, ATWOOD FALCON and ATWOOD EAGLE (See Note 4) included the issuance
of a $3 million unsecured note payable in four annual $750,000 installments.

* Increased by a $10 million prepayment subsequent to September 30, 1996. See
  Note 13.

LINES OF CREDIT --

     The Company has a $10 million short-term line of credit with a bank that is
secured by the pledge of a portion of the Company's United States treasury
bonds. This line of credit is used to satisfy short-term working capital
requirements. At September 30, 1996, there were no outstanding borrowings under
this line of credit. At September 30, 1995, $1.5 million bearing interest of 6
percent was borrowed under this line of credit. See Note 13.

     The Company also has a $3 million unsecured short-term line of credit with
a bank to support issuance, when required, of standby letters of guarantee and
the Indian tax guarantee (see Note 6). At September 30, 1996, standby letters of
guarantee in the aggregate amount of approximately $1 million were outstanding
under this facility.

approximately $3.8 million which are permanently invested abroad. Foreign tax
credits totaling approximately $600,000 are available to reduce the U.S. taxes
on such amounts.

     The Company has United States net operating loss carryforwards totaling
$8.7 million which expire in fiscal years 2001 through 2003 and investment tax
credit carryforwards totaling $2.5 million which expire in fiscal years 1997
through 2001. Due to various utilization limitations, management estimates that
a significant portion of these tax attributes will not be available to reduce
future tax obligations; accordingly, a $4.4 million valuation allowance is
recorded as of September 30, 1996.

     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 a letter of guarantee, the Company received a tax
refund in fiscal year 1994 of $639,000 (net of taxes on interest and other
related expense), which is reflected in the balance sheet as other deferred
credits, pending ultimate resolution of the issue by the Indian High Court.

NOTE 7 -- CAPITAL STOCK

     The Company has a stock option plan ("Stock Plan") under which
non-qualified and incentive stock options may be granted to officers and key
employees through December 5, 2000. The maximum number of shares of common stock
that may be granted under the Stock Plan is 330,000. The Company also has
options outstanding to purchase 23,100 shares under an incentive stock option
plan ("Incentive Plan") which expired for future grant purposes on November
17, 1991. Under both plans, the exercise price of each option equals the market
price of the Company's stock on the date of grant, and all outstanding options
have a maximum term of 10 years. Under the Incentive Plan, options vest over a
period from the fifth to the tenth year from the date of grant and under the
Stock Plan, options vest over a period from the second to the fifth year from
the date of grant.

     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 for its stock option plans. Had
compensation costs been determined based on the fair value at the grant dates
for awards made in fiscal 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):

Net income...........................  As reported          $  11,368
                                       Pro forma               11,291
Earnings per share...................  As reported              $1.71
                                       Pro forma                 1.69

     The fair value of grants made in fiscal 1996 was estimated on the date of
grant using the Black-Scholes option pricing model with the following
weighted-average assumptions used: 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 percent of their
compensation, as defined (the basic contribution). The Company makes a
contribution to the Plan equal to twice the basic contribution. 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. The Company used
$58,000 of forfeitures in fiscal 1996 and $112,000 of forfeitures in fiscal 1995
to reduce its cash contribution requirements, which resulted in actual
contributions of $738,000 in fiscal 1996 and $637,000 in fiscal 1995. In fiscal
1994, the Company made cash contributions of $702,000 and did not utilize any
forfeitures to reduce its contribution requirements. As of September 30, 1996,
there remains approximately $74,000 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 $32.2 million note payable to the bank group has a
market adjustable interest rate and a short maturity, the carrying value of this
instrument approximates fair value. Although the $2.25 million term note has a
fixed 6 percent interest rate at September 30, 1996, it also approximates fair
value. The Company's only financial instruments at September 30, 1995 and 1996
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 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. Drilling revenues for fiscal 1995 include $24.8
million, $16.0 million and $7.5 million in revenues received from Esso Australia
Limited/Esso Production Malaysia, Inc., BHP Petroleum Pty. Ltd. and Woodside
Offshore Petroleum Pty. Ltd., respectively. Drilling revenues for fiscal 1994
included $24.8 million and $6.7 million in revenues received from Esso Australia
Limited/Esso Production Malaysia, Inc. and Western Mining Corporation Limited,
respectively.

NOTE 11 -- 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
(loss) is contract revenues less operating expenses. In computing operating
income (loss) for each geographic area, none of the following items were
considered: investment income or gains on sale of securities, general corporate
expenses, interest expense, minority interest in loss of partnerships and
domestic and foreign income taxes. Identifiable assets are those assets that are

NOTE 13 -- EVENTS (UNAUDITED) SUBSEQUENT TO DATE OF AUDITORS' REPORT

     In January 1997, the Company executed a drilling contract for the ATWOOD
SOUTHERN CROSS which requires substantial refurbishment and upgrade of the rig.
The Company has previously committed to purchase $5 million of long lead-time
equipment for such an upgrade and will incur approximately $20 million of
additional costs to complete the refurbishment and upgrade. Management estimates
that this rig will commence drilling operations in Australia in late fiscal 1997
or early fiscal 1998.

     In conjunction with the upgrade of the ATWOOD HUNTER, the bank group which
holds a mortgage lien on the rig has agreed to provide a waiver of the annual
capital expenditures limit for fiscal 1997, along with some other amendments to
the loan documents; and the Company has agreed to reduce the outstanding loan
amount through a $10 million prepayment, in addition to the quarterly and excess
cash flow payment requirements. For the calendar year 1997, the Company
estimates payments to the bank group will total $22 million, and, accordingly,
such amount has been included in current maturities of long-term notes payable
at December 31, 1996. In addition, the Company has agreed to guaranty $3 million
of the outstanding balance of such bank debt.

     In December 1996, the Company increased its short-term line-of-credit from
a bank from $10 million to $30 million, secured by the pledge of all of the
Company's United States treasury bonds.

     On February 4, 1997, the Company filed a Registration Statement on Form S-3
with the Securities and Exchange Commission with respect to a public offering by
the Company of 1,500,000 shares of common stock. The net proceeds from the
offering will be used by the Company to reduce bank debt and to provide funding
for various planned capital expenditure projects, including the ATWOOD HUNTER
upgrade and the ATWOOD SOUTHERN CROSS refurbishment and upgrade.

                                   attractive semisubmersible candidate for

                                   the Company was awarded a 175-day
                                   drilling contract for the rig, which
                                   should be mobilized to Singapore in
                                   March 1997 to undergo substantial
                                   refurbishment and upgrade, with drilling 
                                   operations in Australia expected to commence
                                   in late fiscal 1997 or early fiscal 1998.

                                   drilling operations. A platform rig
                                   usually stays at a location for several
                                   months, if not years, since several
                                   wells are typically drilled from a
       [PHOTO]                     support platform. RIG-200 is a
                                   technically advanced modular platform
                                   rig for the West Tuna platform offshore
                                   Australia, which uses the latest
                                   technology in mechanized rig-floor and
                                   pipe-deck equipment, as well as
                                   sophisticated instrumentation to monitor
                                   key functions around the rig. The design
                                   and fabrication of the rig were
                                   completed in 1995, and drilling
                                   operations in Australia commenced in

ITEM 17.  UNDERTAKINGS.

     The Company hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report
pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the provisions described under Item 15 above, or otherwise, the
Company has been advised that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of the
Company in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person in connection with the
securities being registered, the Company will, unless, in the opinion of its
counsel, the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     The Company hereby undertakes that:

          (1)  For purposes of determining any liability under the Securities

CREDIT SUISSE FIRST BOSTON CORPORATION
HOWARD, WEIL, LABOUISSE, FRIEDRICHS INCORPORATED,
RAUSCHER PIERCE REFSNES, INC.,
  As Representatives of the Several Underwriters,
   c/o Credit Suisse First Boston Corporation,
      11 Madison Avenue,
      New York, N.Y. 10010

Dear Sirs:

      1. INTRODUCTORY. Atwood Oceanics, Inc., a Texas corporation ("Company"),
proposes to issue and sell to the Underwriters 1,500,000 shares ("Firm
Securities") of its common stock, par value $1.00 per share ("Securities") and
also proposes to issue and sell to the Underwriters, at the option of the
Underwriters, an aggregate of not more than 225,000 additional shares ("Optional
Securities") of its Securities as set forth below. The Firm Securities and the
Optional Securities are herein collectively called the "Offered Securities". The
Company hereby agrees with the several Underwriters named in Schedule A hereto
("Underwriters") as follows:

      2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents
and warrants to, and agrees with, the several Underwriters that:

            (a) A registration statement (No. 333-21065 relating to the Offered
      Securities, including a form of prospectus, has been filed with the
      Securities and Exchange Commission ("Commission") and either (i) has been
      declared effective under the Securities Act of 1933 ("Act") and is not
      proposed to be amended or (ii) is proposed to be amended by amendment or
      post-effective amendment. If such registration statement ("initial
      registration statement") has been declared effective, either (i) an
      additional registration statement ("additional registration statement")
      relating to the Offered Securities may have been filed with the Commission
      pursuant to Rule 462(b) ("Rule 462(b)") under the Act and, if so filed,
      has become effective upon filing pursuant to such Rule and the Offered
      Securities all have been duly registered under the Act pursuant to the
      initial registration statement and, if applicable,

                                    -1-
<PAGE>
      the additional registration statement or (ii) such an additional
      registration statement is proposed to be filed with the Commission
      pursuant to Rule 462(b) and will become effective upon filing pursuant to
      such Rule and upon such filing the Offered Securities will all have been
      duly registered under the Act pursuant to the initial registration
      statement and such additional registration statement. If the Company does
      not propose to amend the initial registration statement or if an
      additional registration statement has been filed and the Company does not
      propose to amend it, and if any post-effective amendment to either such
      registration statement has been filed with the Commission prior to the
      execution and delivery of this Agreement, the most recent amendment (if
      any) to each such registration statement has been declared effective by
      the Commission or has become effective upon filing pursuant to Rule 462(c)
      ("Rule 462(c)") under the Act or, in the case of the additional
      registration statement, Rule 462(b). For purposes of this Agreement,
      "Effective Time" with respect to the initial registration statement or, if
      filed prior to the execution and delivery of this Agreement, the
      additional registration statement means (i) if the Company has advised
      Credit Suisse First Boston Corporation, Howard, Weil, Labouisse Friedrichs
      Incorporated and Rauscher Pierce Refsnes, Inc., as representatives of the
      Underwriters (collectively, the "Representatives") that it does not
      propose to amend such registration statement, the date and time as of
      which such registration statement, or the most recent post-effective
      amendment thereto (if any) filed prior to the execution and delivery of
      this Agreement, was declared effective by the Commission or has become
      effective upon filing pursuant to Rule 462(c), or (ii) if the Company has
      advised the Representatives that it proposes to file an amendment or
      post-effective amendment to such registration statement, the date and time
      as of which such registration statement, as amended by such amendment or
      post-effective amendment, as the case may be, is declared effective by the
      Commission. If an additional registration statement has not been filed
      prior to the execution and delivery of this Agreement but the Company has
      advised the Representatives that it proposes to file one, "Effective Time"
      with respect to such additional registration statement means the date and
      time as of which such registration statement is filed and becomes
      effective pursuant to Rule 462(b). "Effective Date" with respect to the
      initial registration statement or the additional registration statement
      (if any) means the date of the Effective Time thereof. The initial
      registration statement, as amended at its Effective Time, including all
      material incorporated by reference therein, including all information
      contained in the additional registration statement (if any) and deemed to
      be a part of the initial registration statement as of the Effective Time
      of the additional registration statement pursuant to the General
      Instructions of the Form on which it is filed and including all
      information (if any) deemed to be a part of the initial registration
      statement as of its Effective Time pursuant to Rule 430A(b) ("Rule
      430A(b)") under the Act, is hereinafter referred to as the "Initial
      Registration Statement". The additional registration statement, as amended
      at its Effective Time, including the contents of the initial registration
      statement incorporated by reference therein and including all information
      (if any) deemed to be a part of the additional registration statement as
      of its Effective Time pursuant to Rule 430A(b), is hereinafter referred to
      as the "Additional Registration Statement". The Initial Registration
      Statement and the Additional Registration Statement are herein referred to
      collectively as the "Registration Statements" and individually as a
      "Registration Statement". The form of prospectus relating to the Offered
      Securities, as first filed with the Commission pursuant to and in
      accordance with Rule 424(b) ("Rule 424(b)") under the Act or (if no such
      filing is required) as included in a Registration Statement, including all
      material incorporated

                                    -2-
<PAGE>
      by reference in such prospectus, is hereinafter referred to as the
      "Prospectus". No document has been or will be prepared or distributed in
      reliance on Rule 434 under the Act.

            (b) If the Effective Time of the Initial Registration Statement is
      prior to the execution and delivery of this Agreement: (i) on the
      Effective Date of the Initial Registration Statement, the Initial
      Registration Statement conformed in all respects to the requirements of
      the Act and the rules and regulations of the Commission ("Rules and
      Regulations") and did not include any untrue statement of a material fact
      or omit to state any material fact required to be stated therein or
      necessary to make the statements therein not misleading, (ii) on the
      Effective Date of the Additional Registration Statement (if any), each
      Registration Statement conformed, or will conform, in all respects to the
      requirements of the Act and the Rules and Regulations and did not include,
      or will not include, any untrue statement of a material fact and did not
      omit, or will not omit, to state any material fact required to be stated
      therein or necessary to make the statements therein not misleading and
      (iii) on the date of this Agreement, the Initial Registration Statement
      and, if the Effective Time of the Additional Registration Statement is
      prior to the execution and delivery of this Agreement, the Additional
      Registration Statement each conforms, and at the time of filing of the
      Prospectus pursuant to Rule 424(b) or (if no such filing is required) at
      the Effective Date of the Additional Registration Statement in which the
      Prospectus is included, each Registration Statement and the Prospectus
      will conform, in all respects to the requirements of the Act and the Rules
      and Regulations, and neither of such documents includes, or will include,
      any untrue statement of a material fact or omits, or will omit, to state
      any material fact required to be stated therein or necessary to make the
      statements therein not misleading. If the Effective Time of the Initial
      Registration Statement is subsequent to the execution and delivery of this
      Agreement on the Effective Date of the Initial Registration Statement, the
      Initial Registration Statement and the Prospectus will conform in all
      respects to the requirements of the Act and the Rules and Regulations,
      neither of such documents will include any untrue statement of a material
      fact or will omit to state any material fact required to be stated therein
      or necessary to make the statements therein not misleading, and no
      Additional Registration Statement has been or will be filed. The two
      preceding sentences do not apply to statements in or omissions from a
      Registration Statement or the Prospectus based upon written information
      furnished to the Company by any Underwriter through the Representatives
      specifically for use therein, it being understood and agreed that the only
      such information is that described as such in Section 7(b).

            (c) The Company has been duly incorporated and is an existing
      corporation in good standing under the laws of the State of Texas, with
      power and authority (corporate and other) to own its properties and
      conduct its business as described in the Prospectus; and the Company is
      duly qualified to do business as a foreign corporation in good standing in
      all other jurisdictions in which its ownership or lease of property or the
      conduct of its business requires such qualification, except where the
      failure to so qualify would not have a material adverse effect on the
      Company and its subsidiaries taken as a whole.

            (d) Each subsidiary of the Company has been duly incorporated and is
      an existing corporation in good standing under the laws of the
      jurisdiction of its incorporation, with power and authority (corporate and
      other) to own its properties and conduct its business as

                                    -3-
<PAGE>
      described in the Prospectus; and each subsidiary of the Company is duly
      qualified to do business as a foreign corporation in good standing in all
      other jurisdictions in which its ownership or lease of property or the
      conduct of its business requires such qualification, except where the
      failure to so qualify would not have a material adverse effect on the
      Company and its subsidiaries taken as a whole; all of the issued and
      outstanding capital stock of each subsidiary of the Company has been duly
      authorized and validly issued and is fully paid and nonassessable; and the
      capital stock of each subsidiary owned by the Company, directly or through
      subsidiaries, is owned free from liens, encumbrances and defects.

            (e) The Offered Securities and all other outstanding shares of
      capital stock of the Company have been duly authorized; all outstanding
      shares of capital stock of the Company are, and, when the Offered
      Securities have been delivered and paid for in accordance with this
      Agreement on each Closing Date (as defined below), such Offered Securities
      will have been, validly issued, fully paid and nonassessable and will
      conform to the description thereof contained in the Prospectus; and the
      stockholders of the Company have no preemptive rights with respect to the
      Securities.

            (f) Except as disclosed in the Prospectus, there are no contracts,
      agreements or understandings between the Company and any person that would
      give rise to a valid claim against the Company or any Underwriter for a
      brokerage commission, finder's fee or other like payment in connection
      with the offer and sale of the Offered Securities.

            (g) There are no contracts, agreements or understandings between the
      Company and any person granting such person the right to require the
      Company to file a registration statement under the Act with respect to any
      securities of the Company owned or to be owned by such person or to
      require the Company to include such securities in the securities
      registered pursuant to a Registration Statement or in any securities being
      registered pursuant to any other registration statement filed by the
      Company under the Act.

            (h) The Offered Securities have been approved for listing on the
      Nasdaq Stock Market's National Market subject to notice of issuance.

            (i) No consent, approval, authorization, or order of, or filing
      with, any governmental agency or body or any court is required for the
      consummation of the transactions contemplated by this Agreement in
      connection with the issuance and sale of the Offered Securities by the
      Company, except such as have been obtained and made under the Act and such
      as may be required under state securities laws.

            (j) The execution, delivery and performance of this Agreement, and
      the issuance and sale of the Offered Securities will not result in a
      breach or violation of any of the terms and provisions of, or constitute a
      default under, any statute, any rule, regulation or order of any
      governmental agency or body or any court, domestic or foreign, having
      jurisdiction over the Company or any subsidiary of the Company or any of
      their properties, or any agreement or instrument to which the Company or
      any such subsidiary is a party or by which the Company or any such
      subsidiary is bound or to which any of the properties of the Company or
      any such subsidiary is subject which would have a material adverse effect
      on the Company

                                    -4-

      and its subsidiaries taken as a whole, or the charter or by-laws of the
      Company or any such subsidiary, and the Company has full power and
      authority to authorize, issue and sell the Offered Securities as

      related equipment described as being owned by them in the Prospectus, all
      real properties and all other properties and assets owned by them, in each
      case free from liens, encumbrances and defects that would materially
      affect the value thereof or materially interfere with the use made or to
      be made thereof by them, except for mortgages on the Atwood Hunter and
      Atwood Eagle pursuant to the Company's bank credit facility; and except as
      disclosed in the Prospectus, the Company and its subsidiaries hold any
      leased real or personal property under valid and enforceable leases with
      no exceptions that would materially interfere with the use made or to be
      made thereof by them.

            (m) The Company and its subsidiaries possess adequate certificates,
      authorities or permits issued by appropriate governmental agencies or
      bodies necessary to conduct the business now operated by them and have not
      received any notice of proceedings relating to the revocation or
      modification of any such certificate, authority or permit that, if
      determined adversely to the Company or any of its subsidiaries, would
      individually or in the aggregate have a material adverse effect on the
      Company and its subsidiaries taken as a whole.

            (n) No labor dispute with the employees of the Company or any
      subsidiary exists or, to the knowledge of the Company, is imminent that

            (o) The Company and its subsidiaries own, possess or can acquire on

      necessary to conduct the business now operated by them, or presently
      employed by them, and have not received any notice of infringement of or
      conflict with asserted rights of others with respect to any intellectual
      property rights that, if determined adversely to the Company or any of its
      subsidiaries, would individually or in the aggregate have a material
      adverse effect on the Company and its subsidiaries taken as a whole.

            (p) Except as disclosed in the Prospectus, neither the Company nor
      any of its subsidiaries is in violation of any statute, any rule,

      aggregate have a material adverse effect on the Company and its
      subsidiaries taken as a whole; and the Company is not aware of any pending
      investigation which might lead to such a claim.

            (q) Except as disclosed in the Prospectus, there are no pending
      actions, suits or proceedings against or affecting the Company, any of its
      subsidiaries or any of their respective properties that, if determined
      adversely to the Company or any of its subsidiaries, would individually or
      in the aggregate have a material adverse effect on the condition
      (financial or other), business, properties or results of operations of the
      Company and its subsidiaries taken as a whole, or would materially and
      adversely affect the ability of the Company to perform its obligations
      under this Agreement, or which are otherwise material in the context of
      the sale of the Offered Securities; and no such actions, suits or
      proceedings are threatened or, to the Company's knowledge, contemplated.

            (r) The financial statements included in each Registration Statement
      and the Prospectus present fairly the financial position of the Company
      and its consolidated subsidiaries as of the dates shown and their results
      of operations and cash flows for the periods shown, and, except as
      otherwise disclosed in the Prospectus, such financial statements have been
      prepared in conformity with the generally accepted accounting principles
      in the United States applied on a consistent basis and the schedules
      included in each Registration Statement present fairly the information
      required to be stated therein.

            (s) Except as disclosed in the Prospectus, since the date of the
      latest audited financial statements included in the Prospectus there has
      been no material adverse change, nor any development or event involving a
      prospective material adverse change, in the condition (financial or
      other), business, properties or results of operations of the Company and
      its subsidiaries taken as a whole, and, except as disclosed in or
      contemplated by the Prospectus, there has been no dividend or distribution
      of any kind declared, paid or made by the Company on any class of its
      capital stock.

            (t) The Company is not and, after giving effect to the offering and
      sale of the Offered Securities and the application of the proceeds thereof
      as described in the Prospectus, will not be an "investment company" as
      defined in the Investment Company Act of 1940.

      3. PURCHASE, SALE AND DELIVERY OF OFFERED SECURITIES. On the basis of the
representations, warranties and agreements herein contained, but subject to the
terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and the Underwriters agree, severally and not jointly, to purchase
from the Company, at a purchase price of $ __________ per share, the respective
numbers of shares of Firm Securities set forth opposite the names of the
Underwriters in Schedule A hereto.

      The Company will deliver the Firm Securities to the Representatives for
the accounts of the Underwriters, against payment of the purchase price in
Federal (same day) funds by wire transfer to a bank account previously
designated to Credit Suisse First Boston Corporation by the Company, at 9:00
A.M., New York time, on _________, 1997, or at such other time not later than
seven full business days thereafter as Credit Suisse First Boston Corporation
("CSFBC") and the Company

                                    -6-
<PAGE>
determine, such time being herein referred to as the "First Closing Date." For
purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the First
Closing Date (if later than the otherwise applicable settlement date) shall be
the settlement date, for payment of funds and delivery of securities for all the
Offered Securities sold pursuant to the offering. The certificates for the Firm
Securities so to be delivered will be in definitive form, in such denominations
and registered in such names as CSFBC requests and will be made available for
checking and packaging at the above office of CSFBC at least 24 hours prior to
the First Closing Date.

      In addition, upon written notice from CSFBC given to the Company from time
to time not more than 30 days subsequent to the date of the Prospectus, the
Underwriters may purchase all or less than all of the Optional Securities at the
purchase price per Security to be paid for the Firm Securities. The Company
agrees to sell to the Underwriters the number of shares of Optional Securities
specified in such notice and the Underwriters agree, severally and not jointly,
to purchase such Optional Securities. Such Optional Securities shall be
purchased for the account of each Underwriter in the same proportion as the
number of shares of Firm Securities set forth opposite such Underwriter's name
bears to the total number of shares of Firm Securities (subject to adjustment by
CSFBC to eliminate fractions) and may be purchased by the Underwriters only for
the purpose of covering over-allotments made in connection with the sale of the
Firm Securities. No Optional Securities shall be sold or delivered unless the
Firm Securities previously have been, or simultaneously are, sold and delivered.
The right to purchase the Optional Securities or any portion thereof may be
exercised from time to time within the above-described thirty day period and to
the extent not previously exercised may be surrendered and terminated at any
time upon notice by CSFBC to the Company.

      Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CSFBC
but shall be not later than five full business days after written notice of
election to purchase Optional Securities is given. The Company will deliver the
Optional Securities being purchased on each Optional Closing Date to the
Representatives for the accounts of the several Underwriters, against payment of
the purchase price therefor in Federal (same day) funds by wire transfer to a
bank account previously designated to CSFBC by the Company. The certificates for
the Optional Securities being purchased on each Optional Closing Date will be in
definitive form, in such denominations and registered in such names as CSFBC
requests upon reasonable notice prior to such Optional Closing Date and will be
made available for checking and packaging at the above office of CSFBC at a
reasonable time in advance of such Optional Closing Date.

      4. OFFERING BY UNDERWRITERS. It is understood that the several
Underwriters propose to offer the Offered Securities for sale to the public as
set forth in the Prospectus.

      5. CERTAIN AGREEMENTS OF THE COMPANY. The Company agrees with the several
Underwriters that:

            (a) If the Effective Time of the Initial Registration Statement is
      prior to the execution and delivery of this Agreement, the Company will
      file the Prospectus with the Commission pursuant to and in accordance with
      subparagraph (1) (or, if applicable and if

                                    -7-
<PAGE>
      consented to by CSFBC, subparagraph (4)) of Rule 424(b) not later than the
      earlier of (A) the second business day following the execution and
      delivery of this Agreement or (B) the fifteenth business day after the
      Effective Date of the Initial Registration Statement.

      The Company will advise CSFBC promptly of any such filing pursuant to Rule
      424(b). If the Effective Time of the Initial Registration Statement is
      prior to the execution and delivery of this Agreement and an additional
      registration statement is necessary to register a portion of the Offered
      Securities under the Act but the Effective Time thereof has not occurred
      as of such execution and delivery, the Company will file the additional
      registration statement or, if filed, will file a post-effective amendment
      thereto with the Commission pursuant to and in accordance with Rule 462(b)
      on or prior to 10:00 P.M., New York time, on the date of this Agreement
      or, if earlier, on or prior to the time the Prospectus is printed and
      distributed to any Underwriter, or will make such filing at such later
      date as shall have been consented to by CSFBC.

            (b) The Company will advise CSFBC promptly of any proposal to amend
      or supplement the initial or any additional registration statement as
      filed or the related prospectus or the Initial Registration Statement, the
      Additional Registration Statement (if any) or the Prospectus and will not
      effect such amendment or supplementation without CSFBC's consent; and the
      Company will also advise CSFBC promptly of the effectiveness of each
      Registration Statement (if its Effective Time is subsequent to the
      execution and delivery of this Agreement) and of any amendment or
      supplementation of a Registration Statement or the Prospectus and of the
      institution by the Commission of any stop order proceedings in respect of
      a Registration Statement and will use its best efforts to prevent the
      issuance of any such stop order and to obtain as soon as possible its
      lifting, if issued.

            (c) If, at any time when a prospectus relating to the Offered
      Securities is required to be delivered under the Act in connection with
      sales by any Underwriter or dealer, any event occurs as a result of which
      the Prospectus as then amended or supplemented would include an untrue
      statement of a material fact or omit to state any material fact necessary
      to make the statements therein, in the light of the circumstances under
      which they were made, not misleading, or if it is necessary at any time to
      amend the Prospectus to comply with the Act, the Company will promptly
      notify CSFBC of such event and will promptly prepare and file with the
      Commission, at its own expense, an amendment or supplement which will
      correct such statement or omission or an amendment which will effect such
      compliance. Neither CSFBC's consent to, nor the Underwriters' delivery of,
      any such amendment or supplement shall constitute a waiver of any of the
      conditions set forth in Section 6.

            (d) As soon as practicable, but not later than the Availability Date
      (as defined below), the Company will make generally available to its
      security holders an earnings statement covering a period of at least 12
      months beginning after the Effective Date of the Initial Registration
      Statement (or, if later, the Effective Date of the Additional Registration
      Statement) which will satisfy the provisions of Section 11(a) of the Act.
      For the purpose of the preceding sentence, "Availability Date" means the
      45th day after the end of the fourth fiscal quarter following the fiscal
      quarter that includes such Effective Date, except that, if

                                    -8-
<PAGE>
      such fourth fiscal quarter is the last quarter of the Company's fiscal
      year, "Availability Date" means the 90th day after the end of such fourth
      fiscal quarter.

            (e) The Company will furnish to the Representatives copies of each
      Registration Statement (three of which will be signed and will include all
      exhibits), each related preliminary prospectus, and, so long as delivery
      of a prospectus relating to the Offered Securities is required to be
      delivered under the Act in connection with sales by any Underwriter or
      dealer, the Prospectus and all amendments and supplements to such
      documents, in each case in such quantities as CSFBC requests. The
      Prospectus shall be so furnished on or prior to 3:00 P.M., New York time,
      on the business day following the later of the execution and delivery of
      this Agreement or the Effective Time of the Initial Registration
      Statement. All other documents shall be so furnished as soon as available.
      The Company will pay the expenses of printing and distributing to the
      Underwriters all such documents.

            (f) The Company will arrange for the qualification of the Offered
      Securities for sale under the laws of such jurisdictions as CSFBC
      designates and will continue such qualifications in effect so long as
      required for the distribution.

            (g) During the period of five years hereafter, the Company will
      furnish to the Representatives and, upon request, to each of the other
      Underwriters, as soon as practicable after the end of each fiscal year, a
      copy of its annual report to stockholders for such year; and the Company
      will furnish to the Representatives (i) as soon as available, a copy of
      each report and any definitive proxy statement of the Company filed with
      the Commission under the Securities Exchange Act of 1934 or mailed to
      stockholders, and (ii) from time to time, such other information
      concerning the Company as CSFBC may reasonably request.

            (h) The Company will pay all expenses incident to the performance of
      its obligations under this Agreement and for any filing fees and other
      expenses (including fees and disbursements of counsel) incurred by them in
      connection with qualification of the Offered Securities for sale under the
      laws of such jurisdictions as CSFBC designates and the printing of
      memoranda relating thereto for the filing fee of the National Association
      of Securities Dealers, Inc. relating to the Offered Securities, for any
      travel expenses of the Company's officers and employees and any other
      expenses of the Company in connection with attending or hosting meetings
      with prospective purchasers of the Offered Securities and for expenses
      incurred in distributing preliminary prospectuses and the Prospectus
      (including any amendments and supplements thereto) to the Underwriters.

            (i) For a period of 120 days after the date of the initial public
      offering of the Offered Securities, the Company will not offer, sell,
      contract to sell, pledge or otherwise dispose of, directly or indirectly,
      or file with the Commission a registration statement under the Act
      relating to, any additional shares of its Securities or securities
      convertible into or exchangeable or exercisable for any shares of its
      Securities, or publicly disclose the intention to make any such offer,
      sale, pledge, disposal or filing, without the prior written consent of
      CSFBC, except grants of employee stock options pursuant to the terms of a
      plan in effect on

                                    -9-
<PAGE>
      the date hereof, issuances of Securities pursuant to the exercise of such
      options or the exercise of any other employee stock options outstanding on
      the date hereof.

      6. CONDITIONS OF THE OBLIGATIONS OF THE UNDERWRITERS. The obligations of
the several Underwriters to purchase and pay for the Firm Securities on the
First Closing Date and the Optional Securities to be purchased on each Optional
Closing Date will be subject to the accuracy of the representations and
warranties on the part of the Company herein, to the accuracy of the statements
of Company officers made pursuant to the provisions hereof, to the performance
by the Company of its obligations hereunder and to the following additional
conditions precedent:

            (a) The Representatives shall have received a letter, dated the date
      of delivery thereof (which, if the Effective Time of the Initial
      Registration Statement is prior to the execution and delivery of this
      Agreement, shall be on or prior to the date of this Agreement or, if the
      Effective Time of the Initial Registration Statement is subsequent to the
      execution and delivery of this Agreement, shall be prior to the filing of
      the amendment or post-effective amendment to the registration statement to
      be filed shortly prior to such Effective Time), of Arthur Andersen LLP
      confirming that they are independent public accountants within the meaning
      of the Act and the applicable published Rules and Regulations thereunder
      and stating to the effect that:

                  (i) in their opinion the financial statements and schedules
            examined by them and included in the Registration Statements comply
            as to form in all material respects with the applicable accounting
            requirements of the Act and the related published Rules and
            Regulations;

                  (ii) they have performed the procedures specified by the
            American Institute of Certified Public Accountants for a review of
            interim financial information as described in Statement of Auditing
            Standards No. 71, Interim Financial Information, on the unaudited
            financial statements included in the Registration Statements;

                  (iii) on the basis of a reading of the latest available
            interim financial statements of the Company, inquiries of officials
            of the Company who have responsibility for financial and accounting
            matters and other specified procedures, nothing came to their
            attention that caused them to believe that:

                        (A) the unaudited financial statements included in the
                  Registration Statements do not comply as to form in all
                  material respects with the applicable accounting requirements
                  of the Act and the related published Rules and Regulations or
                  any material modifications should be made to such unaudited
                  financial statements for them to be in conformity with
                  generally accepted accounting principles;

                        (B) the unaudited consolidated net sales, net operating
                  income, net income and net income per share amounts for the
                  three-month periods ended December 31, 1996 and 1995 included
                  in the Prospectus do not agree

                                    -10-
<PAGE>
                  with the amounts set forth in the unaudited consolidated
                  financial statements for those same periods or were not
                  determined on a basis substantially consistent with that of
                  the corresponding amounts in the audited statements of income;

                        (C) at the date of the latest available balance sheet
                  read by such accountants, or at a subsequent specified date
                  not more than five days prior to the date of this Agreement,
                  there was any change in the capital stock or any increase in
                  short-term indebtedness or long-term debt of the Company and
                  its consolidated subsidiaries or, at the date of the latest
                  available balance sheet read by such accountants, there was
                  any decrease in consolidated net current assets or net assets,
                  as compared with amounts shown on the latest balance sheet
                  included in the Prospectus; or

                        (D) for the period from the closing date of the latest
                  income statement included in the Prospectus to the closing
                  date of the latest available income statement read by such
                  accountants there were any decreases, as compared with the
                  corresponding period of the previous year and with the period
                  of corresponding length ended the date of the latest income
                  statement included in the Prospectus, in consolidated net
                  sales, in consolidated net operating income, or in the total
                  or per share amounts of consolidated net income.

            except in all cases set forth in clauses (C) and (D) above for
            changes, increases or decreases which the Prospectus discloses have
            occurred or may occur or which are described in such letter; and

                  (iv) they have compared specified dollar amounts (or
            percentages derived from such dollar amounts) and other financial
            information contained in the Registration Statements (in each case
            to the extent that such dollar amounts, percentages and other
            financial information are derived from the general accounting
            records of the Company and its subsidiaries subject to the internal
            controls of the Company's accounting system or are derived directly
            from such records by analysis or computation) with the results
            obtained from inquiries, a reading of such general accounting
            records and other procedures specified in such letter and have found
            such dollar amounts, percentages and other financial information to
            be in agreement with such results, except as otherwise specified in
            such letter.

      For purposes of this subsection, (i) if the Effective Time of the Initial
      Registration Statement is subsequent to the execution and delivery of this
      Agreement, "Registration Statements" shall mean the initial registration
      statement as proposed to be amended by the amendment or post-effective
      amendment to be filed shortly prior to its Effective Time, (ii) if the
      Effective Time of the Initial Registration Statement is prior to the
      execution and delivery of this Agreement but the Effective Time of the
      Additional Registration Statement is subsequent to such execution and
      delivery, "Registration Statements" shall mean the Initial Registration
      Statement and the additional registration statement as proposed to be
      filed or as proposed to

                                    -11-
<PAGE>
      be amended by the post-effective amendment to be filed shortly prior to
      its Effective Time, and (iii) "Prospectus" shall mean the prospectus
      included in the Registration Statements. All financial statements and
      schedules included in material incorporated by reference into the
      Prospectus shall be deemed included in the Registration Statements for
      purposes of this subsection.

            (b) If the Effective Time of the Initial Registration Statement is
      not prior to the execution and delivery of this Agreement, such Effective
      Time shall have occurred not later than 10:00 P.M., New York time, on the
      date of this Agreement or such later date as shall have been consented to
      by CSFBC. If the Effective Time of the Additional Registration Statement
      (if any) is not prior to the execution and delivery of this Agreement,
      such Effective Time shall have occurred not later than 10:00 P.M., New
      York time, on the date of this Agreement or, if earlier, the time the
      Prospectus is printed and distributed to any Underwriter, or shall have
      occurred at such later date as shall have been consented to by CSFBC. If
      the Effective Time of the Initial Registration Statement is prior to the
      execution and delivery of this Agreement, the Prospectus shall have been
      filed with the Commission in accordance with the Rules and Regulations and
      Section 5(a) of this Agreement. Prior to such Closing Date, no stop order
      suspending the effectiveness of a Registration Statement shall have been
      issued and no proceedings for that purpose shall have been instituted or,
      to the knowledge of the Company or the Representatives, shall be
      contemplated by the Commission.

            (c) Subsequent to the execution and delivery of this Agreement,
      there shall not have occurred (i) any change, or any development or event
      involving a prospective change, in the condition (financial or other),
      business, properties or results of operations of the Company or its
      subsidiaries which, in the judgment of a majority in interest of the
      Underwriters including the Representatives, is material and adverse and
      makes it impractical or inadvisable to proceed with completion of the
      public offering or the sale of and payment for the Offered Securities;
      (ii) any downgrading in the rating of any debt securities of the Company
      by any "nationally recognized statistical rating organization" (as defined
      for purposes of Rule 436(g) under the Act), or any public announcement
      that any such organization has under surveillance or review its rating of
      any debt securities of the Company (other than an announcement with
      positive implications of a possible upgrading, and no implication of a
      possible downgrading, of such rating); (iii) any suspension or limitation
      of trading in securities generally on the New York Stock Exchange or on
      the NASDAQ National Stock Market or any setting of minimum prices for
      trading on such exchange, or any suspension of trading of any securities
      of the Company on any exchange or in the overthe counter market; (iv) any
      banking moratorium declared by U.S. Federal or New York authorities; or
      (v) any outbreak or escalation of major hostilities in which the United
      States is involved, any declaration of war by Congress or any other
      substantial national or international calamity or emergency if, in the
      judgment of a majority in interest of the Underwriters including the
      Representatives, the effect of any such outbreak, escalation, declaration,
      calamity or emergency makes it impractical or inadvisable to proceed with
      completion of the public offering or the sale of and payment for the
      Offered Securities.

            (d) The Representatives shall have received an opinion, dated such
      Closing Date, of Griggs & Harrison, P.C., counsel for the Company, to the
      effect that:

                  (i) The Company has been duly incorporated and is an existing
            corporation in good standing under the laws of the State of Texas,
            with corporate power and authority to own its properties and conduct
            its business as described in the Prospectus; and the Company is duly
            qualified to do business as a foreign corporation in good standing
            in all other jurisdictions in which its ownership or lease of
            property or the conduct of its business requires such qualification,
            except where the failure to so qualify would not have a material
            adverse effect on the Company and its subsidiaries, taken as a
            whole;

                  (ii) Each subsidiary of the Company has been duly incorporated
            and is an existing corporation in good standing under the laws of
            the jurisdiction of its incorporation, with power and authority
            (corporate and other) to own its properties and conduct its business
            as described in the Prospectus; and each subsidiary of the Company
            is duly qualified to do business as a foreign corporation in good
            standing in all other jurisdictions in which its ownership or lease
            of property or the conduct of its business requires such
            qualification, except where the failure to so qualify would not have
            a material adverse effect on the Company and its subsidiaries, taken
            as a whole; all of the issued and outstanding capital stock of each
            subsidiary of the Company has been duly authorized and validly
            issued and is fully paid and nonassessable; and the capital stock of
            each subsidiary owned by the Company, directly or through
            subsidiaries, is owned free from liens, encumbrances and defects;

                  (iii) The Offered Securities delivered on such Closing Date
            and all other outstanding shares of the Common Stock of the Company
            have been duly authorized and validly issued, are fully paid and
            nonassessable and conform to the description thereof contained in
            the Prospectus; and the stockholders of the Company have no
            preemptive rights with respect to the Securities;

                  (iv) Such counsel do not know of any legal or governmental
            proceedings required to be described in a Registration Statement or
            the Prospectus which are not described as required or of any
            contracts or documents of a character required to be described in a
            Registration Statement or the Prospectus or to be filed as exhibits
            to a Registration Statement which are not described and filed as
            required;

                  (v) The description of the Company's capital stock
            incorporated by reference in the Prospectus, insofar as such
            statements constitute a summary of documents referred to therein or
            matters of law, are accurate and summarize in all material respects,
            such documents and matters;

                  (vi) There are no contracts, agreements or understandings
            known to such counsel between the Company and any person granting
            such person the right to require the Company to file a registration
            statement under the Act with respect to any securities of the
            Company owned or to be owned by such person or to require the
            Company to include such securities in the securities registered
            pursuant to the

                                    -13-
<PAGE>
            Registration Statement or in any securities being registered
            pursuant to any other registration statement filed by the Company
            under the Act;

                  (vii) The Company is not and, after giving effect to the
            offering and sale of the Offered Securities and the application of
            the proceeds thereof as described in the Prospectus, will not be an
            "investment company" as defined in the Investment Company Act of
            1940;

                  (viii)No consent, approval, authorization or order of, or
            filing with, any governmental agency or body or any court is
            required for the consummation of the transactions contemplated by
            this Agreement in connection with the issuance or sale of the
            Offered Securities by the Company, except such as have been obtained
            and made under the Act and such as may be required under state
            securities laws;

                  (ix) The execution, delivery and performance of this Agreement
            and the issuance and sale of the Offered Securities will not result
            in a breach or violation of any of the terms and provisions of, or
            constitute a default under, any statute, any rule, regulation or
            order of any governmental agency or body or any court having
            jurisdiction over the Company or any subsidiary of the Company or
            any of their properties, or any agreement or instrument included as
            an exhibit to the Registration Statement or any report incorporated
            by reference in the Registration Statement or otherwise known to
            such counsel to which the Company or any such subsidiary is a party
            or by which the Company or any such subsidiary is bound or to which
            any of the properties of the Company or any such subsidiary is
            subject, or the charter or by-laws of the Company or any such
            subsidiary, and the Company has full power and authority to
            authorize, issue and sell the Offered Securities as contemplated by
            this Agreement;

                  (x) This Agreement has been duly authorized, executed and
            delivered by the Company;

                  (xi) The Offered Securities have been approved for listing on
            the NASDAQ National Market System upon official notice of issuance;

                  (xii) The Initial Registration Statement was declared
            effective under the Act as of the date and time specified in such
            opinion, the Additional Registration Statement (if any) was filed
            and became effective under the Act as of the date and time (if
            determinable) specified in such opinion, the Prospectus either was
            filed with the Commission pursuant to the subparagraph of Rule
            424(b) specified in such opinion on the date specified therein or
            was included in the Initial Registration Statement or the Additional
            Registration Statement (as the case may be), and, to the best of the
            knowledge of such counsel, no stop order suspending the
            effectiveness of a Registration Statement or any part thereof has
            been issued and no proceedings for that purpose have been instituted
            or are pending or contemplated under the Act, and each Registration
            Statement and the Prospectus, and each amendment or supplement
            thereto, as of their respective effective or issue dates, complied
            as to form in all

                                    -14-
<PAGE>
            material respects with the requirements of the Act and the Rules and
            Regulations; and

                  (xiii)Such counsel have no reason to believe that any part of
            a Registration Statement or any amendment thereto, as of its
            effective date or as of such Closing Date, contained any untrue
            statement of a material fact or omitted to state any material fact
            required to be stated therein or necessary to make the statements
            therein not misleading or that the Prospectus or any amendment or
            supplement thereto, as of its issue date or as of such Closing Date,
            contained any untrue statement of a material fact or omitted to
            state any material fact necessary in order to make the statements
            therein, in the light of the circumstances under which they were
            made, not misleading; it being understood that such counsel need
            express no opinion as to the financial statements or other financial
            data contained in the Registration Statements or the Prospectus.

                  (xiv) In rendering such opinion, Griggs & Harrison, P.C. may
            rely, as to matters of law of jurisdictions where subsidiaries are
            organized, upon opinions of local counsel. With respect to matters
            of fact, Griggs & Harrison, P.C. may rely, to the extent it deems
            proper, on certificates of officers of the Company and public
            officials.

            (e) The Representatives shall have received from Vinson & Elkins
      L.L.P., counsel for the Underwriters, such opinion or opinions, dated such
      Closing Date, with respect to the incorporation of the Company, the
      validity of the Offered Securities delivered on such Closing Date, the
      Registration Statements, the Prospectus and other related matters as the
      Representatives may require, and the Company shall have furnished to such
      counsel such documents as they request for the purpose of enabling them to
      pass upon such matters.

            (f) The Representatives shall have received a certificate, dated
      such Closing Date, of the President or any Vice-President and a principal
      financial or accounting officer of the Company in which such officers, to
      the best of their knowledge after reasonable investigation, shall state
      that: the representations and warranties of the Company in this Agreement
      are true and correct in all material respects; the Company has complied
      with all agreements and satisfied all conditions on its part to be
      performed or satisfied hereunder at or prior to such Closing Date; no stop
      order suspending the effectiveness of any Registration Statement has been
      issued and no proceedings for that purpose have been instituted or, to the
      Company's knowledge, are contemplated by the Commission; the Additional
      Registration Statement (if any) satisfying the requirements of
      subparagraphs (1) and (3) of Rule 462(b) was filed pursuant to Rule
      462(b), including payment of the applicable filing fee in accordance with
      Rule 111(a) or (b) under the Act, prior to the time the Prospectus was
      printed and distributed to any Underwriter; and, subsequent to the date of
      the most recent financial statements in the Prospectus, there has been no
      material adverse change, nor any development or event involving a
      prospective material adverse change, in the condition (financial or
      other), business, properties or results of operations of the Company and
      its subsidiaries taken as a whole except as set forth in or contemplated
      by the Prospectus or as described in such certificate.

                                    -15-
<PAGE>
            (g) The Representatives shall have received a letter, dated such
      Closing Date, of which meets the requirements of subsection (a) of this
      Section, except that the specified date referred to in such subsection
      will be a date not more than five days prior to such Closing Date for the
      purposes of this subsection.

The Company will furnish the Representatives with such conformed copies of such
opinions, certificates, letters and documents as the Representatives reasonably
request. CSFBC may in its sole discretion waive on behalf of the Underwriters
compliance with any conditions to the obligations of the Underwriters hereunder,
whether in respect of an Optional Closing Date or otherwise.

      7. INDEMNIFICATION AND CONTRIBUTION. (a) The Company will indemnify and
hold harmless each Underwriter against any losses, claims, damages or
liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any related preliminary prospectus, or arise out of or are based
upon the omission or alleged omission to state therein a material fact to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse each Underwriter for any legal or other expenses reasonably
incurred by such Underwriter in connection with investigating or defending any
such loss, claim, damage, liability or action as such expenses are incurred;
provided, however, that the Company will not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement in or omission or alleged
omission from any of such documents in reliance upon and in conformity with
written information furnished to the Company by any Underwriter through the
Representatives specifically for use therein, it being understood and agreed
that the only such information furnished by any Underwriter consists of the
information described as such in subsection (b) below.

            (b) Each Underwriter will severally and not jointly indemnify and
      hold harmless the Company against any losses, claims, damages or
      liabilities to which the Company may become subject, under the Act or
      otherwise, insofar as such losses, claims, damages or liabilities (or
      actions in respect thereof) arise out of or are based upon any untrue
      statement or alleged untrue statement of any material fact contained in
      any Registration Statement, the Prospectus, or any amendment or supplement
      thereto, or any related preliminary prospectus, or arise out of or are
      based upon the omission or the alleged omission to state therein a
      material fact required to be stated therein or necessary to make the
      statements therein not misleading, in each case to the extent, but only to
      the extent, that such untrue statement or alleged untrue statement or
      omission or alleged omission was made in reliance upon and in conformity
      with written information furnished to the Company by such Underwriter
      through the Representatives specifically for use therein, and will
      reimburse any legal or other expenses reasonably incurred by the Company
      in connection with investigating or defending any such loss, claim,
      damage, liability or action as such expenses are incurred, it being
      understood and agreed that the only such information furnished by any
      Underwriter consists of the following information in the Prospectus
      furnished on behalf of each Underwriter: the last paragraph at the bottom
      of the cover page concerning the terms of the offering by the
      Underwriters, the legend concerning over-allotments, stabilizing and
      passive market making

                                    -16-
<PAGE>
      on the inside front cover page, the concession and reallowance figures
      appearing in the paragraph under the caption "Underwriting" and the
      information contained in the fifth paragraph under the caption
      "Underwriting."

            (c) Promptly after receipt by an indemnified party under this
      Section of notice of the commencement of any action, such indemnified
      party will, if a claim in respect thereof is to be made against the
      indemnifying party under subsection (a) or (b) above, notify the
      indemnifying party of the commencement thereof, but the omission so to
      notify the indemnifying party will not relieve it from any liability which
      it may have to any indemnified party otherwise than under subsection (a)
      or (b) above. In case any such action is brought against any indemnified
      party and it notifies the indemnifying party of the commencement thereof,
      the indemnifying party will be entitled to participate therein and, to the
      extent that it may wish, jointly with any other indemnifying party
      similarly notified, to assume the defense thereof, with counsel
      satisfactory to such indemnified party (who shall not, except with the
      consent of the indemnified party, be counsel to the indemnifying party),
      and after notice from the indemnifying party to such indemnified party of
      its election so to assume the defense thereof, the indemnifying party will
      not be liable to such indemnified party under this Section for any legal
      or other expenses subsequently incurred by such indemnified party in
      connection with the defense thereof other than reasonable costs of
      investigation. No indemnifying party shall, without the prior written
      consent of the indemnified party, effect any settlement of any pending or
      threatened action in respect of which any indemnified party is or could
      have been a party and indemnity could have been sought hereunder by such
      indemnified party unless such settlement includes an unconditional release
      of such indemnified party from all liability on any claims that are the
      subject matter of such action.

            (d) If the indemnification provided for in this Section is
      unavailable or insufficient to hold harmless an indemnified party under
      subsection (a) or (b) above, then each indemnifying party shall contribute
      to the amount paid or payable by such indemnified party as a result of the
      losses, claims, damages or liabilities referred to in subsection (a) or
      (b) above (i) in such proportion as is appropriate to reflect the relative
      benefits received by the Company on the one hand and the Underwriters on
      the other from the offering of the Securities or (ii) if the allocation
      provided by clause (i) above is not permitted by applicable law, in such
      proportion as is appropriate to reflect not only the relative benefits
      referred to in clause (i) above but also the relative fault of the Company
      on the one hand and the Underwriters on the other in connection with the
      statements or omissions which resulted in such losses, claims, damages or
      liabilities as well as any other relevant equitable considerations. The
      relative benefits received by the Company on the one hand and the
      Underwriters on the other shall be deemed to be in the same proportion as
      the total net proceeds from the offering (before deducting expenses)
      received by the Company bear to the total underwriting discounts and
      commissions received by the Underwriters. The relative fault shall be
      determined by reference to, among other things, whether the untrue or
      alleged untrue statement of a material fact or the omission or alleged
      omission to state a material fact relates to information supplied by the
      Company or the Underwriters and the parties' relative intent, knowledge,
      access to information and opportunity to correct or prevent such untrue
      statement or omission. The amount paid by an indemnified party as a result
      of the losses, claims, damages or liabilities referred to in the first
      sentence of this subsection (d) shall be

                                    -17-
<PAGE>
      deemed to include any legal or other expenses reasonably incurred by such
      indemnified party in connection with investigating or defending any action
      or claim which is the subject of this subsection (d). Notwithstanding the
      provisions of this subsection (d), no Underwriter shall be required to
      contribute any amount in excess of the amount by which the total price at
      which the Securities underwritten by it and distributed to the public were
      offered to the public exceeds the amount of any damages which such
      Underwriter has otherwise been required to pay by reason of such untrue or
      alleged untrue statement or omission or alleged omission. No person guilty
      of fraudulent misrepresentation (within the meaning of Section 11(f) of
      the Act) shall be entitled to contribution from any person who was not
      guilty of such fraudulent misrepresentation. The Underwriters' obligations
      in this subsection (d) to contribute are several in proportion to their
      respective underwriting obligations and not joint.

            (e) The obligations of the Company under this Section shall be in
      addition to any liability which the Company may otherwise have and shall
      extend, upon the same terms and conditions, to each person, if any, who
      controls any Underwriter within the meaning of the Act; and the
      obligations of the Underwriters under this Section shall be in addition to
      any liability which the respective Underwriters may otherwise have and
      shall extend, upon the same terms and conditions, to each director of the
      Company, to each officer of the Company who has signed a Registration
      Statement and to each person, if any, who controls the Company within the
      meaning of the Act.

      8. DEFAULT OF UNDERWRITERS. If any Underwriter or Underwriters default in
their obligations to purchase Offered Securities hereunder on either the First
or any Optional Closing Date and the aggregate number of shares of Offered
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase does not exceed 10% of the total number of shares of Offered Securities
that the Underwriters are obligated to purchase on such Closing Date, CSFBC may
make arrangements satisfactory to the Company for the purchase of such Offered
Securities by other persons, including any of the Underwriters, but if no such
arrangements are made by such Closing Date, the non-defaulting Underwriters
shall be obligated severally, in proportion to their respective commitments
hereunder, to purchase the Offered Securities that such defaulting Underwriters
agreed but failed to purchase on such Closing Date. If any Underwriter or
Underwriters so default and the aggregate number of shares of Offered Securities
with respect to which such default or defaults occur exceeds 10% of the total
number of shares of Offered Securities that the Underwriters are obligated to
purchase on such Closing Date and arrangements satisfactory to CSFBC and the
Company for the purchase of such Offered Securities by other persons are not
made within 36 hours after such default, this Agreement will terminate without
liability on the part of any non-defaulting Underwriter or the Company, except
as provided in Section 9 (provided that if such default occurs with respect to
Optional Securities after the First Closing Date, this Agreement will not
terminate as to the Firm Securities or any Optional Securities purchased prior
to such termination). As used in this Agreement, the term "Underwriter" includes
any person substituted for an Underwriter under this Section. Nothing herein
will relieve a defaulting Underwriter from liability for its default.

      9. SURVIVAL OF CERTAIN REPRESENTATIONS AND OBLIGATIONS. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and

                                    -18-
<PAGE>
effect, regardless of any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the Company or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Offered Securities. If this Agreement is
terminated pursuant to Section 8 or if for any reason the purchase of the
Offered Securities by the Underwriters is not consummated, the Company shall
remain responsible for the expenses to be paid or reimbursed by it pursuant to
Section 5 and the respective obligations of the Company and the Underwriters
pursuant to Section 7 shall remain in effect, and if any Offered Securities have
been purchased hereunder the representations and warranties in Section 2 and all
obligations under Section 5 shall also remain in effect. If the purchase of the
Offered Securities by the Underwriters is not consummated for any reason other
than solely because of the termination of this Agreement pursuant to Section 8
or the occurrence of any event specified in clause (iii), (iv) or (v) of Section
6(c), the Company will reimburse the Underwriters for all out-of-pocket expenses
(including fees and disbursements of counsel) reasonably incurred by them in
connection with the offering of the Offered Securities.

      10. NOTICES. All communications hereunder will be in writing and, if sent
to the Underwriters, will be mailed, delivered or telegraphed and confirmed to
the Representatives c/o Credit Suisse First Boston Corporation, 11 Madison
Avenue, New York, N.Y. 10010, Attention: Investment Banking
Department-Transactions Advisory Group, or, if sent to the Company, will be
mailed, delivered or telegraphed and confirmed to it at Atwood Oceanics, 15835
Park Ten Place Drive, Houston, Texas 77084, Attention: James M. Holland;
provided, however, that any notice to an Underwriter pursuant to Section 7 will
be mailed, delivered or telegraphed and confirmed to such Underwriter.

      11. SUCCESSORS. This Agreement will inure to the benefit of and be binding
upon the parties hereto and their respective successor and the officers and
directors and controlling persons referred to in Section 7, and no other person
will have any right or obligation hereunder.

      12. REPRESENTATION OF UNDERWRITERS. The Representatives will act for the
several Underwriters in connection with this financing, and any action under
this Agreement taken by the Representatives jointly or by CSFBC acting for the
Representatives will be binding upon all the Underwriters.

      13. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

      14. APPLICABLE LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAWS.

      The Company hereby submits to the non-exclusive jurisdiction of the
Federal and state courts in the Borough of Manhattan in The City of New York in
any suit or proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby.

                                    -19-

Gentlemen:
   
     We have acted as counsel for Atwood Oceanics, Inc., a Texas corporation
(the "Company"), in connection with the proposed offer and sale by the Company
to Credit Suisse First Boston, Howard, Weil, Labouisse, Friedrichs Incorporated,
Rauscher Pierce Refsnes, Inc. and the other underwriters to be named in the
Underwriting Agreement to be executed in connection with such offering (the
"Underwriters"), pursuant to a Prospectus forming a part of the Registration
Statement on Form S-3, Registration No. 333-21065, filed with the Securities and
Exchange Commission (the "Commission") on February 4, 1997, as amended by
Amendment No. 1 thereto to be filed with the Commission on February 11, 1997
(the "Registration Statement"), of up to an aggregate of 1,725,000 shares (the
"Shares") of the Company's common stock, par value $1.00 per share (the
"Common Stock"), including 225,000 shares of Common Stock which may be sold to
the Underwriters to cover over-allotments.
    
     In connection therewith, we have examined, among other things, the
Certificate of Incorporation and Bylaws of the Company, each as amended to date,
and originals or copies certified or otherwise identified to our satisfaction of
records of corporate proceedings which have occurred prior to the date hereof
with respect to the offering, certificates of public officials and of
representatives of the Company, statutes and other instruments and documents, as
a basis for the opinions hereinafter expressed. In rendering such opinions, we
have relied upon certificates of certain public officials and officers of the
Company with respect to the accuracy of the material factual matters contained
in such certificates.

     Based upon the foregoing examination and review, we hereby advise you that,
in our opinion, when (a) the Registration Statement has become effective under
the Securities Act of 1933, as amended, and (b) the Shares have been issued and
sold against payment therefor as contemplated in the Registration Statement and
the Underwriting Agreement, the Shares will be validly issued, fully paid and
nonassessable.

     We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and to the reference to our Firm under the caption
"Legal Matters" in the Prospectus forming a part of the Registration
Statement. In giving this consent, we do not hereby admit that we are within the
category of persons whose consent is required under Section 7 of the Securities
Act of 1933, as amended, and the rules and regulations of the Securities and
Exchange Commission promulgated thereunder.

                                          Very truly yours,
                                          GRIGGS & HARRISON, P.C.

                                                                    EXHIBIT 23.1

                   CONSENT OF INDEPENDENT PUBLIC ACCOUNTANTS
