Recent Developments

Effective November 1, 2000, our Board of Directors changed our fiscal year-end
to December 31 from March 31, which was the fiscal year-end used in our last
report on Form 10-K filed with the SEC. This report covers the nine-month
transition period from April 1, 2000 to December 31, 2000.

Unless the context indicates otherwise, references to fiscal years
indicate the twelve months ended March 31 of that year. For example, fiscal 2000
refers to the twelve-month period ended March 31, 2000.

General Development of Business

Oceaneering International, Inc. is an advanced applied technology company that
provides a comprehensive range of integrated technical services and hardware to
customers who operate in harsh environments such as underwater, space and other
hazardous areas. Oceaneering was organized in 1969 out of the combination of
three diving service companies founded in the early 1960s. Since our
establishment, we have concentrated on the development and marketing of
underwater services and products requiring the use of advanced deepwater
technology. We are one of the world's largest underwater services contractors.
We provide most of our services and products to the oil and gas industry. These
include drilling support, subsea construction, design, lease and operation of
production systems, facilities maintenance and repair, specialty subsea hardware
and specialized onshore and offshore engineering and inspection. We operate in
the United States and 18 other countries. Our international operations,
principally in the North Sea, Africa and the Far East, accounted for
approximately 46% of our revenues, or $142 million, for the nine-month period
ended December 31, 2000.

We operate in five business segments. The segments are contained within
two businesses -- services and products provided to the offshore oil and gas
industry ("Offshore Oil and Gas") and all other services and products ("Advanced
Technologies"). Our business segments within the Offshore Oil and Gas business
are Remotely Operated Vehicles ("ROVs"), Subsea Products, Mobile Offshore
Production Systems and Other Services. We report our Advanced Technologies
business as one segment. In each of our businesses, we have been concentrating
on expanding our capabilities to provide technical solutions to our customers.

OFFSHORE OIL AND GAS. In the last few years, the focus of our Offshore Oil and
Gas business has been toward increasing our asset base for servicing deepwater
projects and subsea completions. Prior to 1996, we purchased most of our
remotely operated vehicles, often referred to as ROVs, which are submersible
vehicles operated from the surface and widely used in the offshore oil and gas
industry. However, in response to increased demand for more powerful systems
operating in deeper water, we expanded our capabilities and established an
in-house facility to design and build ROVs to meet the continued expansion of
our ROV fleet. This facility was established and became fully operational in
January 1998. We have built over 50 ROV systems and we are producing all our new
ROVs in-house. In September 2000, we exchanged our diving-related assets in
Asia, Australia and the Middle East for 11 ROVs. The diving-related assets were
part of our Other Services segment.

In addition to the ROV expansion, we also committed to the construction of
two multiservice vessels, the Ocean Intervention and the Ocean Intervention II,
which went into service in the fourth quarter of calendar 1998 and the third
quarter of calendar 2000, respectively. These multiservice vessels are equipped
with thrusters that allow them to be dynamically positioned, which means the
vessels can maintain a constant position at a location without the use of
anchors. Both vessels can carry and install significant lengths of coiled tubing
or umbilicals required to bring subsea well completions into production
(tie-back to production facilities). These vessels have been designed for use in
pipeline or flowline tie-ins, pipeline crossings and subsea hardware
interventions and installations. These vessels are part of our Other Services
segment.

Through our Multiflex division, we are a leading provider of subsea
hydraulic and electrohydraulic thermoplastic umbilicals. These umbilicals are
the means by which offshore operators control subsea wellhead hydrocarbon flow
rates. We entered this market in March 1994 through our purchase of the
operating subsidiaries of Multiflex International Inc. During fiscal 1999, we
constructed a new umbilical plant in Brazil and relocated, modernized and
increased the capabilities of our umbilical manufacturing facility in Scotland.
The plant in Brazil began operations in fiscal 1999, and the plant in Scotland
was commissioned in early fiscal 2000.

We own two operating mobile offshore production systems, the PB San
Jacinto, acquired in December 1997 and currently under contract offshore
Indonesia, and the floating production, storage and offloading system Ocean
Producer, which has been operating offshore West Africa since December 1991.

In November 1999, we contracted to provide a mobile offshore production
system for development of oil fields offshore Western Australia. We converted a
jackup drilling rig to our third mobile offshore production system for this
multiple year contract. We put the unit on location in January 2001, and our
customer oil companies expect production to begin in mid-calendar 2001.

In November 1995, we contracted with a major oil company for the provision
of a floating production, storage and offloading unit. We converted a crude oil
tanker and delivered the Zafiro Producer to its first operational location off
West Africa in August 1996. In December 1996, the customer exercised an option
to purchase the unit. We continue to participate as a member of the customer's
integrated team to operate and enhance the unit's production facilities.

ADVANCED TECHNOLOGIES. In August 1992 and May 1993, we purchased two businesses
that formed the basis of our Advanced Technologies segment. The first business
designed, developed and operated robotic systems and ROVs specializing in
non-oilfield markets and provided the basis for our expansion into
telecommunications cable laying and burial and commercial theme park animation
in 1993. The second business designed, developed and fabricated spacecraft
hardware and high temperature insulation products.

We intend to continue our strategy of acquiring, as opportunities arise,
additional assets or businesses, to improve our market position or expand into
related service and product lines, either directly through merger, consolidation
or purchase, or indirectly through joint ventures. We are also applying our
skills and technology in further developing business unrelated to the oil and
gas industry and performing services for government agencies and firms in the
telecommunications, aerospace and civil engineering and construction industries.

Description of Business

OFFSHORE OIL AND GAS

Our Offshore Oil and Gas business consists of ROVs, Subsea Products, Mobile
Offshore Production Systems and Other Services.

ROVS. ROVs are submersible vehicles operated from the surface. They are widely
used in the offshore oil and gas industry for a variety of underwater tasks
including drill support, installation and construction support, pipeline
inspection and surveys and subsea production facility operation and maintenance.
ROVs may be outfitted with manipulators, sonar, video cameras, specialized
tooling packages and other equipment or features to facilitate the performance
of specific underwater tasks. We use ROVs at water depths or in situations where
the use of divers would be uneconomical or infeasible. We own 118 work class
ROVs and are the industry leader in providing ROV services on deepwater wells,
which are the most technically demanding. We believe we operate the largest and
most technically advanced fleet of ROVs in the world.

Fiscal year ended March 31, 1999 100,854,000 25%


SUBSEA PRODUCTS. We manufacture a variety of build-to-order specialty subsea
hardware to ISO 9001 quality requirements. These products include hydraulic,
electro-hydraulic and steel tube umbilicals; production control equipment;
pipeline repair

systems; and ROV tooling and work packages. We market these products under the
trade names Multiflex and Oceaneering Intervention Engineering.

Subsea umbilicals and production control equipment are the means by which
offshore well operators control subsea wellhead hydrocarbon flow, monitor
downhole and wellhead conditions and perform chemical injection. Pipeline repair
systems make the effective repair of pipelines and risers possible without
requiring underwater welding. ROV tooling and work packages provide the
operational link between an ROV and permanently installed equipment located on
the sea floor.

MOBILE OFFSHORE PRODUCTION SYSTEMS. We presently own two operating mobile
offshore production systems, the Ocean Producer and the San Jacinto. We own a
third mobile offshore production system, the Ocean Legend, which is on location
offshore Western Australia for our customer oil companies. We expect production
from that unit to begin in mid-calendar 2001. In addition, we operate and
maintain the Zafiro Producer on behalf of a major oil company.

We also undertake engineering and project management of projects related
to mobile offshore production systems. We have managed the conversion of a
jackup to a production unit and in-field modifications to the Zafiro Producer.
We also perform engineering studies for customers evaluating field development
projects.

Fiscal year ended March 31, 1999 31,559,000 8%



OTHER SERVICES. We provide oilfield diving, non-destructive inspection and
testing services and supporting vessel operations, which are utilized
principally in inspection, repair and maintenance activities. We also perform
subsea intervention and hardware installation services from our multiservice
vessels. These services include: subsea well tie-backs; pipeline/flowline
tie-ins and repairs; pipeline crossings; umbilical and other subsea equipment
installations; and subsea intervention.

We supply commercial diving services to the oil and gas industry in the
United States using the traditional techniques of air, mixed gas and saturation
diving, all of which use surface-supplied breathing gas. We do not use divers in
water depths greater than 1,000 feet. We also use atmospheric diving systems,
which enclose the operator in a surface pressure diving suit, in water depths up
to 2,300 feet. In September 2000, we exchanged our diving-related assets in
Asia, Australia and the Middle East for 11 ROVs.

Through our Solus Schall division, we offer a wide range of inspection
services to customers required to obtain third-party inspections to satisfy
contractual structural specifications, internal safety standards or regulatory
requirements. We focus on the inspection of pipelines and onshore fabrication of
offshore facilities for the oil and gas industry. Certain of Solus Schall's
pipeline inspection activities are performed through the use of specialized
x-ray crawlers, which travel inside pipelines, stopping to perform radiographic
inspection of welds.

ADVANCED TECHNOLOGIES

Our Advanced Technologies segment provides underwater intervention, engineering
services and related manufacturing to meet a variety of industrial requirements,
including ship husbandry, search and recovery, subsea telecommunications cable
installation, maintenance and repair, civil works projects and commercial theme
park animation. We do this in part by extending the use of existing assets and
technology developed in oilfield operations to new applications.

We work for customers having specialized requirements in underwater or
other environments outside the oil and gas industry. We provide deep ocean
search and recovery services for governmental bodies, including the U.S. Navy.
In other services for the Navy, we provide various engineering and underwater
services ranging from aircraft salvage and recovery operations to inspection and
maintenance of the Navy's fleet of surface ships and submarines. Through a joint
venture we formed with a subsidiary of Smit Internationale, N.V., we also
maintain and operate deepwater cable lay and maintenance equipment. The current
term of the joint venture agreement expires in March 2006. It automatically
extends for five-year periods unless one of the participants gives cancellation
notice at least one year before the end of the then current term.

We design and operate ROVs that are capable of being worked in water
depths to 25,000 feet. Our other specialized equipment includes ROV cable lay
and maintenance equipment rated to 5,000 feet and deep tow, side scan sonar
systems designed for use in depths to 20,000 feet. In fiscal 2000, we located
and recovered the Mercury space capsule Liberty Bell 7 from a water depth of
16,100 feet.

We also design and develop specialized tools and build ROV systems to
customer specifications for use in deepwater and hazardous environments.

We entered the commercial theme park animation market in 1993. We have
provided mechanical sharks and dinosaurs for use in theme park attractions.

As part of our Advanced Technologies segment, Oceaneering Space and
Thermal Systems directs our efforts towards applying undersea technology and
experience in the space industry. We have worked with the NASA and NASA
subcontractors on a variety of projects, including portable life-support
systems, tools and robotic systems and standards and guidelines to ensure
robotic compatibility for space station equipment and payloads. We also support
NASA by producing space shuttle crew support equipment, including the design,
development and fabrication of spacecraft extravehicular and intravehicular
hardware and soft goods, air crew life-support equipment, mechanical and
electromechanical devices and high temperature insulation. These activities
substantially depend on continued government funding for space programs.

MARKETING

OFFSHORE OIL AND GAS. Oil and gas exploration and development expenditures
fluctuate from year to year. In particular, budgetary approval for more
expensive drilling and production in deepwater, an area in which we have a high
degree of focus, may be postponed or suspended during periods when exploration
and production companies reduce their offshore capital spending.

We market our ROVs, Subsea Products and Other Services to domestic,
international and foreign national oil and gas companies engaged in offshore
exploration, development and production. We also provide services as a
subcontractor to other oilfield service companies operating as prime
contractors. Customers for these services typically award contracts on a
competitive bid basis. These contracts are typically less than one year in
duration.

We market our Mobile Offshore Production Systems primarily to
international and foreign national oil and gas companies. We offer systems for
extended well testing, early production and development of marginal fields and
prospects in areas lacking pipelines and processing infrastructure. Contracts
are typically awarded on a competitive basis, generally for periods of one or
more years.

In connection with the services we perform in our Offshore Oil and Gas
business, we generally seek contracts that compensate us on a dayrate basis.
Under dayrate contracts, the contractor provides the ROV or vessel and the
required personnel to operate the unit. Compensation under a dayrate contract is
based on a rate per day for each day the unit is used. The typical dayrate
depends on market conditions, the nature of the operations to be performed, the
duration of the work, the equipment and services to be provided, the
geographical areas involved and other variables. Dayrate contracts may also
contain an alternate, lower dayrate that applies when a unit is in route to a
new site or when operations are interrupted or restricted by equipment
breakdowns, adverse weather or water conditions or other conditions beyond the
contractor's control. Some dayrate contracts provide for revision of the
specified dayrates in the event of material changes in certain items of cost
being incurred by the contractor.

ADVANCED TECHNOLOGIES. We market our marine services and related engineering
services to government agencies, major defense contractors, NASA subcontractors
and telecommunications, construction and other industrial customers outside the
energy sector. We also market to insurance companies, salvage associations and
other customers who have requirements for specialized operations in deep water.

MAJOR CUSTOMERS. Our top five customers in the nine-month period ended December
31, 2000 accounted for 29% of our consolidated revenues. Our top five customers
in fiscal 2000 and 1999 accounted for approximately 25% of our consolidated
revenues in each year. For the nine-month period ended December 31, 2000 and for
fiscal 2000, four of our top five customers were oil and gas exploration and
production companies served by our Offshore Oil and Gas business segments. The
remaining top five customer was the U.S. Navy, which was served by our Advanced
Technologies segment. In fiscal 1999, our top five customers were all oil and
gas exploration and production companies served by our Offshore Oil and Gas
business segments. No single customer accounted for more than 10% of our
consolidated revenues in any of those three periods. While we do not depend on
any one customer, the loss of one of our significant customers could, at least
on a short-term basis, have an adverse effect on our results of operations.

RAW MATERIALS

Most of the raw materials we use in our manufacturing operations, such as
steel in various forms, electronic components and plastics, are available from
many sources, and we are not dependent on any single supplier or source for any
of our raw materials. However, some components we use to manufacture subsea
umbilicals are available from limited sources. While we have not experienced any
difficulties in obtaining those materials in the past and do not anticipate any
such difficulties in the foreseeable future, it is possible that a shortage of
supply could develop. Any significant, prolonged shortage of these materials
could result in increased costs for these materials and delays in our subsea
umbilicals manufacturing operations.

COMPETITION

Our businesses are highly competitive.

OFFSHORE OIL AND GAS.

ROVS. We are the world's largest owner/operator of work class ROVs
employed in oil and gas related operations, with an estimated 33% market share.
At December 31, 2000 we had 118 work class ROVs in service. We compete with
several major companies on a worldwide basis and with numerous others operating
locally in various areas. We have fewer competitors in deeper water depths, as
more sophisticated equipment and technology is needed in deeper water. We
estimate that, during calendar 2000, we provided ROV drilling support on
approximately 50% of the wells drilled worldwide in water depths of 1,000 feet
or more and approximately 60% of the wells drilled worldwide in water depths of
3,000 feet or more.

Competition for ROV services historically has been based on equipment
availability, location of or ability to deploy the equipment, quality of service
and price. The relative importance of these factors can vary from year to year
based on market conditions. The ability to develop improved equipment and
techniques and to attract and retain skilled personnel is also an important
competitive factor in our markets.

MOBILE OFFSHORE PRODUCTION SYSTEMS. We believe we are well positioned to compete
in this market through our ability to identify and offer optimum solutions,
supply equipment and utilize the expertise in associated subsea technology and
offshore construction and operations gained through our extensive operational
experience worldwide. We are one of many companies that offer leased mobile
offshore production systems.

SUBSEA PRODUCTS. Although there are many competitors offering either specialized
products or operating in limited geographic areas, we believe we are one of a
small number of companies that compete on a worldwide basis for the provision of
thermoplastic subsea control umbilical cables.

OTHER SERVICES. We believe we are one of several companies that provide
underwater services on a worldwide basis. We compete for contracts with
companies that have worldwide operations, as well as numerous others operating
locally in various areas. We believe that our ability to provide a wide range of
underwater services, including technological applications in deeper water
(greater than 1,000 feet) on a worldwide basis, should enable us to compete
effectively in the oilfield exploration and development market. In some cases
involving projects that require less sophisticated equipment, small companies
have been able to bid for contracts at prices uneconomic to us. We no longer
provide diving services outside of the United States.

The worldwide inspection market consists of a wide range of inspection and
certification requirements in many industries. Solus Schall competes in only
selected portions of this market. We believe that our broad geographic sales and
operational coverage, long history of operations, technical reputation,
application of x-ray pipeline inspection technology and accreditation to
international quality standards enable us to compete effectively in our selected
inspection services market segments.

Frequently, oil and gas companies use prequalification procedures that
reduce the number of prospective bidders for their projects. In some countries,
political considerations tend to favor local contractors. While these
considerations have not materially impacted this segment's results in recent
periods, our view of the increasing trend to favor local contractors in West
Africa was a factor in our decisions to sell our diving operations in West
Africa in fiscal 2000 and to exchange our diving-related assets in Asia,
Australia and the Middle East for ROVs in September 2000.

ADVANCED TECHNOLOGIES. We believe our specialized ROV assets and experience in
deepwater operations give us an advantage in obtaining contracts in water depths
greater than 5,000 feet. We have fewer competitors in deeper water depths due to
the advanced technical knowledge and sophisticated equipment required for
deepwater operations.

Engineering services is a very broad market with a large number of
competitors. We compete in specialized areas in which we can combine our
extensive program management experience, mechanical engineering expertise and
the capability to continue the development of conceptual project designs into
the manufacture of prototype equipment.

We also use the administrative and operational support structures of our
Offshore Oil and Gas business to identify opportunities in foreign countries and
to provide additional local support for services provided to this segment's
customers.

SEASONALITY, BACKLOG AND RESEARCH AND DEVELOPMENT

A material amount of our consolidated revenues is generated from contracts for
marine services in the Gulf of Mexico and the North Sea, which are usually more
active from April through November compared to the rest of the year. However,
our exit from the diving sector in the North Sea in early 1998 and the
substantial number of multi-year ROV contracts we entered into since 1997 have
reduced the seasonality of our ROV and Other Services operations. Revenues in
our Mobile Offshore Production Systems, Subsea Products and Advanced
Technologies segments are generally not seasonal.

The amounts of backlog orders we believe to be firm as of December 31,
2000 and March 31, 2000 were as follows:

No material portion of our business is subject to renegotiation of profits
or termination of contracts by the United States government.

Our research and development expenditures were approximately $5 million,
$4 million and $5 million during the nine-month period ended December 31, 2000,
fiscal 2000 and fiscal 1999, respectively. These amounts do not include the
expenditures by others in connection with joint research activities in which we
participated or expenditures we incurred in connection with research conducted
during the course of performing our operations.

REGULATION

Our operations are affected from time to time and in varying degrees by foreign
and domestic political developments and foreign, federal and local laws and
regulations. In particular, oil and gas production operations and economics are
affected by tax, environmental and other laws relating to the petroleum
industry, by changes in such laws and by constantly changing administrative
regulations. Those developments may directly or indirectly affect our operations
and those of our customers.

Compliance with federal, state and local provisions regulating the
discharge of materials into the environment or relating to the protection of the
environment has not had a material impact on our capital expenditures, earnings
or competitive position.

While not a legal requirement, within our Offshore Oil and Gas business we
maintain various quality management systems. Our quality management systems in
the United Kingdom and Norway are certified to the equivalent of ISO 9001 and
cover all our Offshore Oil and Gas products and services. The quality management
systems of our Subsea Products segment are certified to ISO 9001 for its
products and services. The quality management systems of both the Oceaneering
Space and Thermal Systems and Oceaneering Technologies units of our Advanced
Technologies segment are also certified to ISO 9001. ISO 9001 is an
internationally recognized verification system for quality management
established by the International Standards Organization.

RISKS AND INSURANCE

WE DERIVE MOST OF OUR REVENUES FROM COMPANIES IN THE OFFSHORE OIL AND GAS
INDUSTRY, A HISTORICALLY CYCLICAL INDUSTRY WITH LEVELS OF ACTIVITY THAT ARE
SIGNIFICANTLY AFFECTED BY THE LEVELS AND VOLATILITY OF OIL AND GAS PRICES.

We derive most of our revenues from customers in the offshore oil and gas
exploration, development and production industry. The offshore oil and gas
industry is a historically cyclical industry characterized by significant
changes in the levels of exploration and development activities. Oil and gas
prices, and market expectations of potential changes in those prices,
significantly affect the levels of those activities. Worldwide political,
economic and military events have contributed to oil and gas price volatility
and are likely to continue to do so in the future. Any prolonged reduction in
the overall level of offshore oil and gas exploration and development
activities, whether resulting from changes in oil and gas prices or otherwise,
could materially and adversely affect our financial condition and results of
operations in our segments within our offshore oil and gas business. Some
factors that have affected and are likely to continue affecting oil and gas
prices and the level of demand for our services and products include the
following:

o worldwide demand for oil and gas;

o the ability of the Organization of Petroleum Exporting Countries, or
OPEC, to set and maintain production levels and pricing;

o the level of production by non-OPEC countries;

o domestic and foreign tax policy;

o laws and governmental regulations that restrict exploration and
development of oil and gas in various offshore jurisdictions;

o advances in exploration and development technology;

o the political environment of oil-producing regions;

o the price and availability of alternative fuels; and

o overall economic conditions.

OUR INTERNATIONAL OPERATIONS INVOLVE ADDITIONAL RISKS NOT ASSOCIATED WITH
DOMESTIC OPERATIONS.

A significant portion of our revenues is attributable to operations in foreign
countries. These activities accounted for approximately 46% of our consolidated
revenues in the nine-month ended December 31, 2000. Risks associated with our



8
9

operations in foreign areas include risks of:

o war and civil disturbances or other risks that may limit or disrupt
markets;

o expropriation, confiscation or nationalization of assets;

o renegotiation or nullification of existing contracts;

o foreign exchange restrictions;

o foreign currency fluctuations;

o foreign taxation;

o the inability to repatriate earnings or capital;

o changing political conditions;

o changing foreign and domestic monetary policies; and

o regional economic downturns.

Additionally, in some jurisdictions we are subject to foreign governmental
regulations favoring or requiring the awarding of contracts to local contractors
or requiring foreign contractors to employ citizens of, or purchase supplies
from, a particular jurisdiction. These regulations may adversely affect our
ability to compete.

Our exposure to the risks we described above varies from country to
country. In recent periods, political instability and civil unrest in Indonesia
and West Africa and general economic downturns in Asia and Brazil have been our
greatest concerns. There is a risk that a continuation or worsening of these
conditions could materially and adversely impact our future business,
operations, financial condition and results of operations. Of our total
consolidated revenues for the nine-month period ended December 31, 2000, we
generated approximately 2% from our operations in Indonesia, 12% from our
operations in West Africa, 8% from our operations in Asia excluding Indonesia
and 7% from our operations in Brazil.

OUR OFFSHORE OILFIELD OPERATIONS INVOLVE A VARIETY OF OPERATING HAZARDS AND
RISKS THAT COULD CAUSE LOSSES.

Our operations are subject to the hazards inherent in the offshore
oilfield business. These include blowouts, explosions, fires, collisions,
capsizings and severe weather conditions. These hazards could result in personal
injury and loss of life, severe damage to or destruction of property and
equipment, pollution or environmental damage and suspension of operations. We
may incur substantial liabilities or losses as a result of these hazards. While
we maintain insurance protection against some of these risks, and seek to obtain
indemnity agreements from our customers requiring the customers to hold us
harmless from some of these risks, our insurance and contractual indemnity
protection may not be sufficient or effective to protect us under all
circumstances or against all risks. The occurrence of a significant event not
fully insured or indemnified against or the failure of a customer to meet its
indemnification obligations to us could materially and adversely affect our
results of operations and financial condition.

LAWS AND GOVERNMENTAL REGULATIONS MAY ADD TO OUR COSTS OR ADVERSELY AFFECT OUR
OPERATIONS.

Our business is affected by changes in public policy and by federal,
state, local and foreign laws and regulations relating to the energy industry.
Oil and gas exploration and production operations are affected by tax,
environmental and other laws relating to the petroleum industry, by changes in
those laws and changes in related administrative regulations. It is also
possible that these laws and regulations may in the future add significantly to
our operating costs or those of our customers or otherwise directly or
indirectly affect our operations.

ENVIRONMENTAL LAWS AND REGULATIONS CAN INCREASE OUR COSTS, AND OUR FAILURE TO
COMPLY WITH THOSE LAWS AND REGULATIONS CAN EXPOSE US TO SIGNIFICANT LIABILITIES.

Risks of substantial costs and liabilities related to environmental
compliance issues are inherent in our operations. Our operations are subject to
extensive federal, state, local and foreign laws and regulations relating to the
generation, storage, handling, emission, transportation and discharge of
materials into the environment. Permits are required for the operation of
various facilities, and those permits are subject to revocation, modification
and renewal. Governmental authorities have the power to enforce compliance with
their regulations, and violations are subject to fines, injunctions or both. In
some cases, those governmental requirements can impose liability for the entire
cost of cleanup on any responsible party without regard to negligence or fault
and impose liability on us for the conduct of or conditions others have caused,
or for our acts that complied with all applicable requirements when we performed
them. It is possible that other developments, such as stricter environmental
laws and regulations, and claims for damages to property or persons resulting
from our operations, would result in substantial costs and liabilities. Our
insurance policies and the contractual indemnity protection we seek to obtain
from our customers may not be sufficient or effective to protect us under all
circumstances or against all risks involving compliance with environmental laws
and regulations.

EMPLOYEES

As of December 31, 2000, we had approximately 3,000 employees. Our workforce
varies seasonally and peaks during the summer months. Approximately 9% of our
employees are represented by unions. We consider our relations with our
employees to be satisfactory.

Financial Information about Geographic Areas

For financial information about our geographic areas of operation, please see
the table in Note 6 of the Notes to Consolidated Financial Statements in this
report, which presents revenues and assets attributable to each of our
geographic areas for the nine-month period ended December 31, 2000 and for the
fiscal years ended March 31, 2000 and 1999.

ITEM 2. PROPERTIES.

See Item 1 -- "Business -- Description of Business -- Offshore Oil and Gas" and
"Business -- Description of Business -- Advanced Technologies" for a description
of equipment and manufacturing facilities used in providing our services and
products.

We maintain office, shop and yard facilities in various parts of the world
to support our operations. We consider these facilities, which we describe
below, to be suitable for their intended use. In these locations, we typically
lease or own office facilities for our administrative and engineering staff,
shops equipped for fabrication, testing, repair and maintenance activities and
warehouses and yard areas for storage and mobilization of equipment to work
sites. All sites are available to support any of our business segments as the
need arises. The groupings which follow associate our significant offices with
the primary business segment they serve.

OFFSHORE OIL AND GAS. In general, our ROV and Other Services segments share
facilities. The largest location is in Morgan City, Louisiana and consists of
ROV manufacturing and training facilities, open and covered storage space and
offices. The Morgan City facilities primarily support operations in the United
States. The regional support offices for our North Sea and Southeast Asia
operations are located in Aberdeen, Scotland and Singapore, respectively. We
also have operational bases in various other locations, the most significant of
which are in Norway, Australia, Indonesia and Nigeria.

We use workshop and office space in Houston, Texas in both our Mobile
Offshore Production Systems and Subsea Products business segments. Our
manufacturing facilities for our Subsea Products segment are located in or near
Houston, Texas, Edinburgh, Scotland and Rio de Janeiro, Brazil. Each of these
manufacturing facilities is suitable for its intended purpose and has sufficient
excess capacity to respond to increases in demand for our subsea products that
may be reasonably anticipated in the foreseeable future. Operations of the
mobile offshore production unit Ocean Producer are supported through our
regional office in Aberdeen. Operations of the San Jacinto and the Ocean Legend
are supported from our office in Perth, Australia, which we opened in fiscal
2000.

Our principal manufacturing facilities are located on properties we own or
hold under a long-term lease, expiring in 2014. The other facilities we use in
our Offshore Oil and Gas business segments are on properties we lease.

ADVANCED TECHNOLOGIES. Our primary facilities for our Advanced Technologies
segment are leased offices and workshops in Upper Marlboro, Maryland, which
support our services for the U.S. Navy and our commercial theme park animation
activities. We also lease facilities in Houston, Texas, which primarily support
our space industry activities and our subsea telecommunications installation
joint venture.

ITEM 3. LEGAL PROCEEDINGS.

In the ordinary course of business, we are subject to actions for damages
alleging personal injury under the general maritime laws of the United States,
including the Jones Act, for alleged negligence. We report actions for personal
injury to our insurance carriers and believe that the settlement or disposition
of those suits will not have a material effect on our financial position or
results of operations. For additional information, see "Commitments and
Contingencies -- Litigation" in Note 5 of the Notes to Consolidated Financial
Statements included in this report.

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS.

We are including the following discussion to inform our existing and potential
security holders generally of some of the risks and uncertainties that can
affect our company and to take advantage of the "safe harbor" protection for
forward-looking statements that applicable federal securities law affords.

From time to time, our management or persons acting on our behalf make
forward-looking statements to inform existing and potential security holders
about our company. These statements may include projections and estimates
concerning the timing and success of specific projects and our future backlog,
revenues, income and capital spending. Forward-looking statements are generally
accompanied by words such as "estimate," "project," "predict," "believe,"
"expect," "anticipate," "plan," "goal" or other words that convey the
uncertainty of future events or outcomes. In addition, sometimes we will
specifically describe a statement as being a forward-looking statement and refer
to this cautionary statement.

In addition, various statements this report contains, including those that
express a belief, expectation or intention, as well as those that are not
statements of historical fact, are forward-looking statements. Those
forward-looking statements appear in Item 1 -- "Business," Item 2 --
"Properties" and Item 3 -- "Legal Proceedings" in Part I of this report and in
Item 7 -- "Management's Discussion and Analysis of Financial Condition and
Results of Operations," Item 7A -- "Quantitative and Qualitative Disclosures
About Market Risk" and in the Notes to Consolidated Financial Statements
incorporated into Item 8 of Part II of this report and elsewhere in this report.
These forward-looking statements speak only as of the date of this report, we
disclaim any obligation to update these statements, and we caution you not to
rely unduly on them. We have based these forward-looking statements on our
current expectations and assumptions about future events. While our management
considers these expectations and assumptions to be reasonable, they are
inherently subject to significant business, economic, competitive, regulatory
and other risks, contingencies and uncertainties, most of which are difficult to
predict and many of which are beyond our control. These risks, contingencies and
uncertainties relate to, among other matters, the following:

o general economic and business conditions and industry trends;

o the continued strength of the industry segments in which we are
involved;

o decisions about offshore developments to be made by oil and gas
companies;

o the highly competitive nature of our businesses;

o our future financial performance, including availability, terms and
deployment of capital;

o the continued availability of qualified personnel;

o operating risks normally incident to offshore exploration, development
and production operations;

o changes in, or our ability to comply with, government regulations,
including those relating to the environment;

o rapid technological changes; and

o social, political and economic situations in foreign countries where
we do business.

We believe the items we have outlined above are important factors that
could cause our actual results to differ materially from those expressed in a
forward-looking statement made in this report or elsewhere by us or on our
behalf. We have discussed most of these factors in more detail elsewhere in this
report. These factors are not necessarily all the important factors that could
affect us. Unpredictable or unknown factors we have not discussed in this report
could also have material adverse effects on actual results of matters that are
the subject of our forward-looking statements. We do not intend to update our
description of important factors each time a potential important factor arises.
We advise our security holders that they should (1) be aware that important
factors we do not refer to above could affect the accuracy of our
forward-looking statements and (2) use caution and common sense when considering
our forward-looking statements.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATION.

All statements in this Form 10-K, other than statements of historical facts,
including, without limitation, statements regarding our business strategy, plans
for future operations and industry conditions, are forward-looking statements
made pursuant to the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995. These forward-looking statements are subject to various
risks, uncertainties and assumptions, including those we refer to under the
heading "Cautionary Statement Concerning Forward-Looking Statements" in Part I
of this report. Although we believe that the expectations reflected in such
forward-looking statements are reasonable, because of the inherent limitations
in the forecasting process, as well as the relatively volatile nature of the
industries in which we operate, we can give no assurance that those expectations
will prove to have been correct. Accordingly, evaluation of our future prospects
must be made with caution when relying on forward-looking information.

Liquidity and Capital Resources

We consider our liquidity and capital resources adequate to support our
operations and internally generated growth initiatives. At December 31, 2000, we
had working capital of $50 million. Additionally, we had $50 million available
under committed credit facilities.

We expect operating cash flow to meet our ongoing annual cash
requirements, including debt service. Net cash provided by operating activities
was $41 million for the nine-month period ended December 31, 2000, $38 million
for the nine-month period ended December 31, 1999, $53 million for fiscal 2000
and $59 million for fiscal 1999.

Working capital was $50 million at December 31, 2000 compared to $53
million at the end of fiscal 2000 and $41 million at the end of fiscal 1999.

Capital expenditures for the nine-month period ended December 31, 2000 and
for the fiscal years ended March 31, 2000 and 1999 were $102 million, $81
million and $102 million, respectively. Capital expenditures during the
nine-month period ended December 31, 2000 consisted of expenditures for the
conversion of a jackup drilling rig to a mobile offshore production unit, the
Ocean Legend, for initial use offshore Western Australia under a three-year
contract, ROV additions and construction costs to complete our second
multiservice vessel. Capital expenditures in fiscal 2000 consisted of
construction costs for the second multiservice vessel, additions to our ROV
fleet and the start of the conversion of the Ocean Legend. Capital expenditures
in fiscal 1999 consisted of additions to our ROV fleet, construction costs for
two multiservice vessels, one of which was placed in service prior to March 31,
1999, a new umbilical plant in Brazil and the relocation and upgrading of our
umbilical plant in Scotland.

Commitments for capital expenditures at December 31, 2000 were
approximately $5 million for completion of the conversion of the Ocean Legend.

In April 1997, we approved a plan to purchase up to a maximum of 3 million
shares of our common stock, and 2.9 million shares were purchased under this
plan through December 31, 2000, at a total cost of $40 million. We did not
repurchase any shares of common stock during the nine-month period ended
December 31, 2000.

At December 31, 2000, we had long-term debt of $180 million and a 47%
debt-to-total capitalization ratio. In September 1998, we issued $100 million of
6.72% Senior Notes to be repaid from 2006 through 2010. We used the proceeds
from the sale of those notes to repay the then outstanding indebtedness under
our prior revolving credit facility, which had been incurred in the funding of
capital expenditures and repurchases of common stock. In October 1998, we
replaced that revolving credit agreement with a new five-year, $80 million
revolving credit facility, under which we had $65 million in outstanding
borrowings and $15 million available for future borrowings at December 31, 2000.
In March 2000, we added a $50 million term loan facility, which is available for
drawing until March 30, 2001 and is to be repaid through April 2004. At December
31, 2000, we had $15 million in outstanding borrowings and $35 million available
for future borrowings under the term loan facility.

Because of our significant foreign operations, we are exposed to currency
fluctuations and exchange risks. We generally minimize these risks primarily
through matching, to the extent possible, revenues and expenses in the various
currencies in which we operate. Cumulative translation adjustments as of
December 31, 2000 relate primarily to our permanent investments in and loans to
our foreign subsidiaries. Inflation has not had a material effect on us in the
past two years and no such effect is expected in the near future.

See Item 1 -- "Business -- Description of Business -- Risks and
Insurance".

In response to (1) continued increasing demand to support deepwater
drilling and (2) identified future construction and production maintenance work,
we extended our ROV fleet expansion program in 1997 by announcing plans for
additional new ROVs. These new vehicles are designed for use around the world in
water depths to 10,000 feet and in severe weather conditions. We have added over
50 ROVs to our fleet during the last several years and we plan to add additional
vehicles at a rate dependent on market demand.

In the past few years, we have sold or exchanged our foreign
diving-related assets to concentrate on our other deepwater services and
products which have potential for higher margins:

- In April 1997, we sold our North Sea diving assets, including a
diving support vessel;

- In fiscal 2000, we sold our West Africa diving and related vessel
assets;

- In September 2000, we exchanged our Asia, Australia and Middle East
diving assets, including a diving support vessel, for 11 ROVs.

In the nine-month period ended December 31, 2000, ROV revenues were 9% higher
than the comparable nine-month period of the prior year. Gross margin percentage
rose 2%. These increases were the result of more ROVs available for service and
an increase in ROV utilization from 63% to 67%. In fiscal 2000, ROV revenues
declined 6% from fiscal 1999 despite our additions to the ROV fleet. Utilization
declined from 82% to 62%. Both of our major oilfield ROV markets, drill support
and construction support, were adversely affected as oil and gas companies had
lower capital spending levels than those in the prior year. We anticipate ROV
utilization and margins to increase in 2001 from increased demand as more
floating deepwater drilling rigs return to service and from a rise in offshore
construction-related activities.

Subsea Products revenues were 52% higher for the nine-month period ended
December 31, 2000 than those of the comparable period of the prior year. This
increase was primarily due to (1) increased demand in Brazil and the U.S., as
oil and gas companies proceeded with offshore capital projects which had been
delayed, and (2) a large steel tube umbilical order in the U.K. While total
gross margin was $2.0 million higher, margin percentages were relatively flat,
as increased profitability in Brazil and the U.S. was offset by the large steel
tube umbilical order in our U.K. plant, which earned a low margin. Subsea
Products revenues were down 4% in fiscal 2000 from fiscal 1999, despite the
addition of an umbilical plant in Brazil and the opening of our upgraded
facility in Scotland. Umbilical sales and margins were adversely affected by low
market demand, as oil and gas companies had lower capital spending levels than
those in the prior years, particularly in Brazil. We anticipate improved Subsea
Product results in 2001 from increased subsea completion activity.

Mobile Offshore Production Systems revenues were down 13% for the
nine-month period ended December 31, 2000 from the comparable period of the
prior year, as production-based revenues from the Ocean Producer were lower due
to declining production levels and we had lower project management and
engineering service revenues from lower demand. As of April 2001, the Ocean
Producer unit is on a day-to-day contract. We have a letter of intent to
contract the unit for a period of seven years to produce from another property
in the area. Gross margin percentage was higher due to $4.3 million of gains on
the sales of two out-of-service semisubmersible rigs. In addition, we wrote down
the carrying value of our out-of-service tanker, the OCEAN VENTURE, by $2.5
million as our assessment of the market it was targeted for, conversion into
production service, had changed. This tanker is not of the size prevalently in
demand in the current market and there have been few opportunities to bid the
vessel. Therefore, we wrote this vessel down to its estimated market value.
Mobile Offshore Production Systems fiscal 2000 revenues were 24% lower than
fiscal 1999, as we completed a major modification project for the Zafiro
Producer during the year. In addition, production-based revenues from the Ocean
Producer were lower due to declining production levels. We anticipate improved
Mobile Offshore Production Systems results in 2001 with the commencement of
Ocean Legend operations.

Other Services revenues were 16% lower in the nine-month period ended
December 31, 2000 than the comparable period of the prior year. The lower
revenues reflect our dispositions of (1) our West Africa diving operations in
fiscal 2000 and (2) our Asia, Australia and Middle East diving operations in
September 2000, along with more competitive conditions resulting from lower
capital expenditures by our oilfield customers. Gross margins were lower due to
lower vessel utilization and related services in the Gulf of Mexico. Other
Services revenues were up 10% in fiscal 2000 from fiscal 1999, primarily due to
a full year of operations from the multiservice vessel Ocean Intervention.
However, margins reflected very competitive market conditions resulting from
reduced oilfield capital spending. The net operating loss was attributed to two
large fixed-price jobs in India. We anticipate improved Other Services results
in 2001 from higher demand for our oilfield services in general, including our
multiservice vessels.

ADVANCED TECHNOLOGIES. The table below sets out revenues and profitability for
this segment for the nine-month periods ended December 31, 2000 and 1999 and the
fiscal years ended March 31, 2000 and 1999.



Nine-Month Period Fiscal Year
Ended December 31, Ended March 31,
---------------------- -----------------------
(dollars in thousands) 2000 1999 2000 1999
----------------------------------------------------------------------------

(unaudited)
Revenues $ 82,012 $ 94,304 $122,971 $ 99,242
Gross Margin 12,039 14,390 20,399 15,649
Gross Margin % 15% 15% 17% 16%
Operating Income 5,035 8,346 12,276 8,459
Operating Income % 6% 9% 10% 9%


Advanced Technologies revenues were 13% lower in the nine-month period
ended December 31, 2000 than the comparable period of the prior year as the
prior period included a large outfall job in Southeast Asia, which was performed
using resources associated with our Other Services segment. These resources were
part of those we exchanged in September 2000 for ROVs. Margins were lower as the
December 2000 period included provisions totaling $1.8 million relating to
operations of a division we no longer own. Advanced Technologies revenues in
fiscal 2000 were 24% higher than in fiscal 1999 due to increased work levels for
the Navy, the outfall job in Southeast Asia and more search and recovery work.
Margin percentages were relatively unchanged. We anticipate similar results from
Advanced Technologies in the next year, contingent upon the level of government
funding for NASA and U.S. Navy programs in which we currently participate or are
pursuing.

OTHER. Interest expense increased over the three year period as a result of our
increased borrowings to fund capital expenditures and repurchases of common
stock. Interest expense is net of capitalized interest of $3.0 million for the
nine- month period ended December 31, 2000, $1.8 million for fiscal 2000 and
$2.5 million for fiscal 1999.

Our effective tax rate, determined after consideration of valuation
allowances and foreign, state and local taxes, was 36%, 36% and 38% for the
nine-month period ended December 31, 2000 and for fiscal 2000 and fiscal 1999,
respectively.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We are currently exposed to certain market risks arising from transactions we
have entered into in the normal course of business. These risks relate to
interest rate changes and fluctuations in foreign exchange rates. We do not
believe these risks are material. We have not entered into any market risk
sensitive instruments for trading purposes. We manage our exposure to interest
rate changes through the use of a combination of fixed and floating rate debt.
See Note 3 of Notes to Consolidated Financial Statements included in this report
for a description of our long-term debt agreements, interest rates and
maturities. We believe that significant interest rate changes will not have a
material near-term impact on our future earnings or cash flows. We manage our
exposure to changes in foreign exchange rates primarily through arranging
compensation in U.S. dollars or freely convertible currency and, to the extent
possible, by limiting compensation received in other currencies to amounts
necessary to meet obligations denominated in those currencies. We believe that a
significant fluctuation in the foreign exchange rates would not have a material
near-term effect on our future earnings or cash flows.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Oceaneering International, Inc.:

We have audited the accompanying consolidated balance sheets of Oceaneering
International, Inc. (a Delaware corporation) and subsidiaries as of December 31,
2000 and March 31, 2000 and the related consolidated statements of income, cash
flows and shareholders' equity and comprehensive income for the nine-month
period ended December 31, 2000 and for each of the two years in the period ended
March 31, 2000. These consolidated 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 auditing standards generally
accepted in the United States. 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Oceaneering
International, Inc. and subsidiaries as of December 31, 2000 and March 31, 2000
and the results of their operations and their cash flows for the nine-month
period ended December 31, 2000 and each of the two years in the period ended
March 31, 2000, in conformity with accounting principles generally accepted in
the United States.

OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES



NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF MAJOR ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of Oceaneering
International, Inc. and its 50% or more owned and controlled subsidiaries
("Oceaneering"). Oceaneering accounts for its investments in unconsolidated
affiliated companies under the equity method. All significant intercompany
accounts and transactions have been eliminated.

Effective November 1, 2000, Oceaneering's Board of Directors approved the change
of its year end to December 31 from March 31. This report covers the nine-month
transition period ended December 31, 2000. The accompanying financial statements
for the nine-month period ended December 31, 1999 are unaudited. Management has
reflected all adjustments which it believes are necessary to present fairly
Oceaneering's results of operations and cash flows for that nine-month period.
All such adjustments are of a normal recurring nature. The results for the
nine-month periods are not necessarily indicative of annual results.

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and highly liquid investments
with original maturities of three months or less from the date of the
investment.

Prepaid Expenses and Other Current Assets

Prepaid expenses and other current assets consisted of the following:



December 31, March 31,
(in thousands) 2000 2000
------------------------------------------------------------------

Spare parts for remotely operated vehicles $10,568 $ 7,950
Inventories, primarily raw materials 8,848 5,593
Other 7,603 5,447
------- -------
Total $27,019 $18,990
======= =======




Inventory is priced at lower of cost or market. Oceaneering determines cost
using the weighted-average method.


Property and Equipment and Goodwill

Oceaneering provides for depreciation of property and equipment primarily on the
straight-line method over estimated useful lives of three to 20 years for marine
services equipment, up to 12 years for mobile offshore production equipment and
three to 25 years for buildings, improvements and other equipment. Goodwill
arising from business acquisitions is amortized on the straight-line method over
15 years.

The costs of repair and maintenance of property and equipment are
charged to operations as incurred, while the costs of improvements are
capitalized. Oceaneering accrues in advance for anticipated drydocking expenses
of its larger vessels. Accrued drydock costs, which are included in accrued
liabilities on the balance sheet, were $3.2 million and $2.4 million at December
31, 2000 and March 31, 2000, respectively. Interest is capitalized on assets
where the construction period is anticipated to be more than three months.
Oceaneering does not allocate general administrative costs to capital projects.
Upon the disposition of property and equipment, the related cost and accumulated
depreciation accounts are relieved and the resulting gain or loss is included as
an adjustment to cost of services and products.

During the nine-month period ended December 31, 2000, Oceaneering
exchanged its diving-related assets, including a vessel, in Asia, Australia and
the Middle East for 11 remotely operated vehicles. The assets acquired were
recorded at their fair market value and the transaction did not result in a
material gain or loss to Oceaneering.

OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES


Management periodically, and upon the occurrence of a triggering event,
reviews the realizability of goodwill and other long-term assets and makes any
appropriate impairment adjustments and disclosures required by Statement of
Financial Accounting Standards Board Standard Number ("SFAS") 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of." During the nine-month period ended December 31, 2000, Oceaneering recorded
a $2.5 million impairment adjustment in the form of additional depreciation
included in cost of services and products within the Mobile Offshore Production
Systems business segment. This adjustment decreased the carrying value of an
out-of-service tanker to its estimated market value. No other impairment
adjustments were made during the periods presented.

Revenue Recognition

Oceaneering's revenues are primarily derived from billings under contracts that
provide for specific time, material and equipment charges, which are accrued
daily and billed monthly. Significant lump-sum contracts, particularly in the
Subsea Products segment, are accounted for using the percentage-of-completion
method. Under this method, we measure the extent of progress toward completion
based on the ratio of costs incurred to total estimated costs at completion.
Unbilled revenues related to recoverable costs and accrued profits on contracts
in process are included in accounts receivable on Oceaneering's balance sheets.
These amounts were $40 million and $43 million at December 31, 2000 and March
31, 2000, respectively. Revenues on contracts with a substantial element of
research and development are recognized to the extent of cost until such time as
the probable final profitability can be determined. Anticipated losses on
contracts, if any, are recorded in the period that such losses are first
determinable. Oceaneering's revenue recognition accounting policies comply with
SEC Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial
Statements."

Income Taxes

Oceaneering accounts for income taxes in accordance with SFAS 109, "Accounting
for Income Taxes."

Foreign Currency Translation

The functional currency for several of Oceaneering's foreign subsidiaries is the
applicable local currency. Results of operations for foreign subsidiaries with
functional currencies other than the U.S. dollar are translated into U.S.
dollars using average exchange rates during the period. Assets and liabilities
of these foreign subsidiaries are translated into U.S. dollars using the
exchange rates in effect at the balance sheet date and the resulting translation
adjustments are accumulated as a component of shareholders' equity. All foreign
currency transaction gains and losses are recognized currently in the
Consolidated Statements of Income.

Earnings Per Share

Oceaneering has computed earnings per share in accordance with SFAS 128,
"Earnings Per Share."

Other Long-term Liabilities

At December 31, 2000 and March 31, 2000, other long-term liabilities include
$9.1 million and $9.3 million, respectively, for self-insurance reserves not
expected to be paid out in the following year and $19.1 million for deferred
income taxes at each period end.

Reclassifications

Certain amounts from prior years, particularly segment information, have been
reclassified to conform with the current year presentation.

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, 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.

OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES


New Accounting Standard

In June 1999, the Financial Accounting Standards Board amended SFAS 133
"Accounting for Derivative Instruments and Hedging Activities," by issuing SFAS
137 to defer the effective date of SFAS 133 to fiscal years beginning after June
15, 2000. Oceaneering believes the adoption of this statement will not have a
significant impact on its results of operations or financial position.


2. INCOME TAXES

Oceaneering and its domestic subsidiaries, including acquired companies from
their respective dates of acquisition, file a consolidated U.S. federal income
tax return. Oceaneering conducts its international operations in a number of
locations which have varying codes and regulations with regard to income and
other taxes, some of which are subject to interpretation. On a geographic basis,
income before minority interests and income taxes attributable to the United
States was $6.7 million, $10.5 million and $18.4 million for the nine-month
period ended December 31, 2000 and the years ended March 31, 2000 and 1999,
respectively. Income taxes are provided at the appropriate tax rates in
accordance with Oceaneering's interpretation of the respective tax regulations
after review and consultation with its internal tax department, tax consultants
and, in some cases, legal counsel in the various jurisdictions. Management
believes that adequate provisions have been made for all taxes which will
ultimately be payable.

Deferred income taxes are provided for temporary differences in the
recognition of income and expenses for financial and tax reporting purposes.
Oceaneering's policy is to provide for deferred U.S. income taxes on
unrepatriated foreign income only to the extent such income is not to be
invested indefinitely in the related foreign entity.

The provisions for income taxes were as follows:

During the nine-month period ended December 31, 2000, Oceaneering also
received a cash tax refund of $4,353,000.

As of December 31, 2000, Oceaneering's United Kingdom subsidiary had net
operating loss carryforwards ("NOLs") of approximately $11 million, which are
available to reduce future United Kingdom Corporation Tax which would otherwise
be payable.

As of December 31, 2000 and March 31, 2000, Oceaneering's worldwide deferred
tax assets and liabilities and related valuation reserves were as follows:



December 31, March 31,
(in thousands) 2000 2000

Deferred tax liabilities $ 19,123 $ 19,123

OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES


Oceaneering's gross deferred tax assets consist primarily of NOLs in its
United Kingdom subsidiary, which have no expiration date, and insurance claim
reserves for which a tax deduction has not yet been allowed. Deferred tax
liabilities consist primarily of depreciation and amortization book/tax
differences and provisions for income of foreign subsidiaries expected to be
repatriated.

Oceaneering has established a valuation allowance for deferred tax assets
after taking into account factors that are likely to affect Oceaneering's
ability to utilize the tax assets. In particular, Oceaneering conducts its
business through several foreign subsidiaries and, although Oceaneering expects
its consolidated operations to be profitable, there is no assurance that profits
will be earned in entities or jurisdictions which have NOLs available. Since
April 1, 1998, changes in the valuation allowance primarily relate to the
expected utilization of foreign NOLs and realization of foreign tax credits.
Income taxes, computed by applying the federal statutory income tax rate of 35%
to income before income taxes and minority interests, are reconciled to the
actual provisions for income taxes as follows:

Long-term Debt, net of current portion $ 180,000 $ 128,000
========= =========


In September 1998, Oceaneering issued $100 million aggregate principal
amount of 6.72% Senior Notes due 2010. The net proceeds were $98.6 million after
issuance costs and were used to retire existing debt. The notes have an average
life of ten years and are scheduled to be paid in five equal annual installments
beginning September 2006.

In October 1998, Oceaneering entered into an $80 million revolving credit
facility (the "Credit Agreement") to replace its prior revolving credit
agreement. There is a commitment fee ranging from .20% to .25% per annum,
depending on Oceaneering's debt-to-capitalization ratio, on the unused portion
of the banks' commitments. Principal maturity is in October 2003. Under the
Credit Agreement, Oceaneering has the option to borrow dollars at the London
Interbank Offered Rate ("LIBOR") plus a margin ranging from .50% to 1.00%,
depending on Oceaneering's debt-to-capitalization ratio, or at the agent bank's
prime rate.

In March 2000, Oceaneering entered into a four-year, $50 million term loan
agreement (the "Term Loan"). Borrowings under the Term Loan can be made until
March 2001 and principal repayments commence in October 2001 with final maturity
in April 2004. There are no commitment fees on the Term Loan. Under the Term
Loan, Oceaneering has the




29
30


OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES


option to borrow dollars at LIBOR plus a margin ranging from .75% to 1.25%,
depending on Oceaneering's debt-to- capitalization ratio, or at the agent bank's
prime rate.

All of these credit arrangements contain similar restrictive covenants as
to minimum net worth, debt-to-capitalization ratio, fixed charge coverage,
interest coverage and restricted payments. Restricted payments, which include
dividends and treasury stock purchases, are limited from April 1, 1998, on a net
basis, to the sum of $25 million plus 50% of Oceaneering's consolidated net
income after April 1, 1998, plus cash proceeds from any sales of common stock.

Oceaneering has uncommitted credit agreements with banks totaling $29
million for use for borrowings and letters of credit. As of December 31, 2000,
Oceaneering had approximately $17 million in letters of credit outstanding under
these agreements.

Cash interest payments of $6.7 million, $7.7 million and $5.7 million were
made in the nine-month period ended December 31, 2000 and the fiscal years ended
March 31, 2000 and 1999, respectively. Interest charges of $3.0 million, $1.8
million and $2.5 million were capitalized as part of construction in progress in
the nine-month period ended December 31, 2000 and the fiscal years ended March
31, 2000 and 1999, respectively.

4. EMPLOYEE BENEFIT PLANS AND SHAREHOLDER RIGHTS PLAN

Retirement Investment Plans

Oceaneering has three separate employee retirement investment plans which, taken
together, cover most of its full-time employees. The Oceaneering Retirement
Investment Plan is a deferred compensation plan in which domestic employees may
participate by deferring a portion of their gross monthly salary and directing
Oceaneering to contribute the deferred amount to the plan. Oceaneering matches a
portion of the deferred compensation. Oceaneering's contributions to the plan
were $3,220,000, $2,867,000 and $2,508,000 for the plan years ended December 31,
2000, 1999 and 1998, respectively.

The second plan is the Oceaneering International Services Pension Scheme
for employees in the United Kingdom. Under this plan, employees may contribute a
portion of their gross monthly salary. Oceaneering also contributes an amount
equal to a portion of the participant's gross monthly salary. The plan assets
exceed vested benefits and are not material to the assets of Oceaneering.
Company contributions to this plan for the nine-month period ended December 31,
2000 and the fiscal years ended March 31, 2000 and 1999 were $41,000, $32,000
and $34,000, respectively.

The third plan is the Oceaneering International, Inc. Supplemental
Executive Retirement Plan, which covers selected key management employees and
executives of Oceaneering as approved by the Compensation Committee of
Oceaneering's Board of Directors (the "Compensation Committee"). This plan
replaced a prior Executive Retirement Plan effective June 30, 1997 and covers
more employees. Expense related to the prior plan during the year ended March
31, 1998 was $576,000. Under the new plan, Oceaneering accrues an amount
determined as a percentage of the participant's gross monthly salary and the
amounts accrued are treated as if they are invested in one or more investment
vehicles pursuant to this plan. Expense related to this plan during the
nine-month period ended December 31, 2000 and the fiscal years ended March 31,
2000 and 1999 was $921,000, $972,000 and $980,000, respectively.

Incentive and Stock Option Plans

Under the 1996, 1999 and 2000 Incentive Plans (the "Incentive Plans"), a
total of 1,165,000, 1,450,000 and 900,000 shares of common stock of Oceaneering,
respectively, were made available for awards to employees and other persons
(excluding nonemployee directors except with respect to automatic grants as
described below and, with respect to the 2000 Incentive Plan, excluding
executive officers) having an important business relationship or affiliation
with Oceaneering. Under the 1999 Incentive Plan, each director of Oceaneering is
automatically granted an option to purchase 10,000 shares of common stock on the
date the director becomes a nonemployee director and each year thereafter at an
exercise price per share equal to the fair market value of a share of common
stock on the date the option was granted. These options become fully exercisable
six months following the date of grant. The Incentive Plans are administered by
the Compensation Committee, which determines the type or types of award(s) to be
made to each participant and sets forth in the related award agreement the
terms, conditions and limitations applicable to each award. The Compensation
Committee may grant stock options, stock appreciation rights and stock and cash
awards. The exercise price for each option is not less than the fair market
value of the optioned shares at the date of grant. Options outstanding vest over
a three- or four-year period and are exercisable over a period of four, five or
ten years after the date of grant or five years after the date of vesting.

OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES



During fiscal 1999 and 2000 and the nine-month period ended December 31,
2000, the Compensation Committee granted restricted common stock of Oceaneering
to certain of its key executives. These grants are subject to earning
requirements on the basis of a percentage change between the price of the common
stock of Oceaneering versus the average of the common stock price of a peer
group of companies over one-, three- and two-year time periods, respectively. Up
to one-half of the grant made in the nine-month period ended December 31, 2000
and up to one-third of the total grant made in fiscal 2000 may be earned each
year depending on Oceaneering's cumulative common stock performance, with any
amount earned subject to vesting in four equal installments over a four-year
period, conditional upon continued employment. All of the total grant made in
fiscal 1999 was earned at the end of one year, subject to vesting. At the time
of each vesting, a participant receives a tax assistance payment for which the
participant must reimburse Oceaneering if the vested common stock is sold by the
participant within three years after the vesting date. As of December 31, 2000,
none of the grant made in the nine-month period ended December 31, 2000 has been
earned and one-third of the grant made in fiscal 2000 has been earned. As of
December 31, 2000, a total of 705,250 shares of restricted stock was outstanding
under these and former, similar grants, of which 325,250 shares were earned,
subject to vesting requirements. The numbers and weighted average grant date
fair values of restricted stock granted were 16,000 and $19.87, respectively,
during the nine-month period ended December 31, 2000, 549,000 and $17.06,
respectively, during fiscal 2000 and 9,000 and $16.83, respectively, during
fiscal 1999. In June 1998 and June 1999, certain key executives also elected to
receive restricted common stock of Oceaneering totaling 35,920 and 42,812 shares
with grant date fair values of $17.94 and $16.56 per share, respectively,
subject to similar vesting requirements and tax assistance payments, in lieu of
cash for all or part of their fiscal 1998 and fiscal 1999 bonus awards. Each
grantee of shares of restricted stock mentioned in this paragraph is deemed to
be the record owner of those shares during the restriction period, with the
right to vote and receive any dividends on those shares.

Oceaneering accounts for stock options it issues under its plans pursuant
to Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees," under which no compensation cost is recognized unless options are
granted at an option price below the fair market value of the stock at the date
of the grant. Had compensation cost for these stock options been determined
consistent with SFAS 123, "Accounting for Stock-Based Compensation,"
Oceaneering's pro forma net income for the nine-month period ended December 31,
2000 and for fiscal 2000 and fiscal 1999 would have been $9,137,000, $15,442,000
and $24,735,000, respectively, and its diluted earnings per share for those
periods would have been $0.39, $0.67 and $1.08, respectively.

At December 31, 2000, there were 760,820 shares of Oceaneering common
stock under these plans available for grant, awarding stock options, stock
appreciation rights, stock and cash awards to employees, subject to no more than
517,220 shares being used for awards other than stock options or stock
appreciation rights to employees.

Shareholder Rights Plan

On November 20, 1992, Oceaneering's Board of Directors adopted a Shareholder
Rights Plan and, in accordance with the plan, declared a dividend of one
preferred share purchase right for each outstanding share of Oceaneering common
stock. The plan will cause substantial dilution to a party that attempts to
acquire Oceaneering in a manner or on terms not approved by the Board of
Directors, except pursuant to an offer conditioned on a substantial number of
rights being acquired.

The rights, which do not have voting rights and are not entitled to
dividends until such time as they become exercisable, expire in December 2002.

5. COMMITMENTS AND CONTINGENCIES

Lease Commitments

At December 31, 2000, Oceaneering occupied several facilities under
noncancellable operating leases expiring at various dates through 2023. Future
minimum rentals under these leases are as follows:

Rental expense, which includes hire of vessels, specialized equipment and
real estate rental, was approximately $13 million, $22 million and $18 million
for the nine-month period ended December 31, 2000 and the fiscal years ended
March 31, 2000 and 1999, respectively.

Insurance

Oceaneering self-insures for workers' compensation, maritime employer's
liability and comprehensive general liability claims to levels it considers
financially prudent and carries insurance after it reaches the initial claim
levels, which can be by occurrence or in the aggregate. Oceaneering determines
the level of accruals by reviewing its historical experience and current year
claim activity. It does not record accruals on a present-value basis.
Oceaneering reviews each claim with insurance adjusters and establishes specific
reserves for all known liabilities. It establishes an additional reserve for
incidents incurred but not reported to Oceaneering for each year using
management estimates and based on prior experience. Oceaneering's management
believes that Oceaneering has established adequate accruals for uninsured
expected liabilities arising from those obligations.

Litigation

Various actions and claims are pending against Oceaneering, most of which are
covered by insurance. In the opinion of Oceaneering's management, the ultimate
liability, if any, which may result from these actions and claims will not
materially affect Oceaneering's financial position or results of operations.

Letters of Credit

Oceaneering had $17 million in letters of credit outstanding as of both December
31, 2000 and March 31, 2000 as guarantees in force for self-insurance
requirements and various performance and bid bonds which are usually for a
period of one year or the duration of the applicable contract.

Financial Instruments and Risk Concentration

Financial instruments which potentially subject Oceaneering to concentrations of
credit risk are primarily cash and cash equivalents, long-term bank and other
borrowings and accounts receivable. The carrying values of cash and cash
equivalents and bank borrowings approximate their fair values due to the short
maturity of those instruments or the short- term duration of the associated
interest rate periods. Accounts receivable are generated from a broad and
diverse group of customers primarily from within the energy industry, which is
Oceaneering's major source of revenues. Oceaneering maintains an allowance for
doubtful accounts based on expected collectibility.

Oceaneering estimated the fair value of its $100 million of 6.72% Senior
Notes (see Note 3) to be $94 million as of December 31, 2000. This estimate was
arrived at by computing the present value of the future principal and interest
payments using a yield-to-maturity interest rate for securities of similar
quality and term.

6. OPERATIONS BY BUSINESS SEGMENT AND GEOGRAPHIC AREA

Business Segment Information

Income (loss) from operations for each business segment is determined
before interest income or expense, other income (expense), minority interests
and provision for income taxes. An allocation of these items is not considered
practical. All assets specifically identified with a particular business segment
have been segregated. Cash and cash equivalents, certain prepaid expenses and
other current assets, certain investments and other assets have not been
allocated to particular business segments.

No individual customer accounted for more than 10% of Oceaneering's
consolidated revenues in the nine-month period ended December 31, 2000 or the
years ended March 31, 2000 and 1999.
