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 22 other countries. Our international operations,
principally in the North Sea, Africa and the Far East, accounted for
approximately 50% of our 2000 revenues, or $209 million.

      This year we are increasing our reporting segments from three to five to
assist the investment community in better understanding our company. 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 are
reporting 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 .


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


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 addition to the ROV expansion, we also committed to the construction of
two multiservice vessels , the Ocean Intervention and the Ocean Intervention II,
the first of which went into service in November 1998. 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 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 year 1999 and the plant in
Scotland was commissioned in early fiscal year 2000.

      We own two mobile offshore production systems, the PB San Jacinto,
acquired in December 1997 and 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 are presently converting a jackup drilling
rig to a mobile offshore production system for this contract. We anticipate
having the unit on location by 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 the
non-oilfield

                                        2
<PAGE>   3

market 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 95 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.


      Our ROV services revenues accounted for approximately 23% of our total
revenues for 2000, 25% of our total revenues for 1999 and 23% of our total
revenues for 1998.

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.


      Our Subsea Products sales revenues accounted for approximately 17% of our
total revenues for 2000, 18% of our total revenues for 1999 and 17% of our total
revenues for 1998.

MOBILE OFFSHORE PRODUCTION SYSTEMS. We presently own two operating mobile
offshore production systems, the Ocean Producer and the San Jacinto and are
converting a third, the Ocean Legend, from a jackup drilling rig. 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. In addition, we own two out-of-service semi- submersible offshore rigs
and a tanker, each capable of being converted to a mobile offshore production
system or other suitable service.

      Our Mobile Offshore Production Systems revenues accounted for
approximately 6% of our total revenues for 2000, 8% of our total revenues for
1999 and 9% of our total revenues for 1998.

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

                                       3
<PAGE>   4

services from our multiservice vessels. These services include: subsea well
tie-backs; pipeline/flowline tie-ins and repairs; pipeline crossings; and
umbilical, other subsea equipment installations and subsea intervention.


      We supply commercial diving services to the oil and gas industry 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.


      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 independently inside pipelines, stopping to perform
radiographic inspection of welds.

      Our Other Services revenues accounted for approximately 25% of our total
revenues for 2000, 24% of our total revenues for 1999 and 27% of our total
revenues for 1998.


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 vehicles. The initial
term of the joint venture agreement expires in March 2001. 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 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.

      Our Advanced Technologies revenues accounted for approximately 29% of our
total revenues for 2000, 25% of our total revenues for 1999 and 24% of our total
revenues for 1998.

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 each of 2000, 1999 and 1998 accounted
for approximately 25%, 25% and 26%, respectively, of our consolidated revenues.
For 2000 and 1998, four of our top five customers were oil and gas exploration
and production companies served by our Offshore Oil and Gas business segments.
For each of those years, the remaining top five customer was the U.S. Navy,
which was served by our Advanced Technologies segment. In 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 years. 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 28%
market share. At March 31, 2000 we had 95 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 we provided ROV drilling support on approximately 50% of
the wells drilled worldwide in water depths of 1,000 feet or more and
approximately 65% 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

                                       5
<PAGE>   6
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 the
other worldwide companies and 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.


      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 decision to sell our diving operations in West Africa
in 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 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.

   *  Represents amounts that were not expected to be performed within one year.


      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 $4 million,
$5 million and $4 million during 2000, 1999 and 1998, 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 formal 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

Our operations are subject to all the risks normally incident to offshore
exploration, development and production, including claims under U.S. maritime
laws. These risks could result in damage to or loss of property, suspension of
operations and injury to or death of personnel. We insure our real and personal
property and equipment. Our vessels are insured against damage or loss including
war and pollution risks. We also carry workers' compensation, maritime
employer's liability, general liability, including third-party pollution and
other insurance customary in our businesses. We carry our insurance at levels of
coverage and deductibles which we consider financially prudent. On some
contracts, we may have certain risks for loss or damage to the customer's
facilities or for unexpected weather delays, which we may cover by special
insurance when we deem it advisable. In some jurisdictions, claims in personal
injury actions against us may include claims for amounts of punitive damages
that may not be covered by insurance.


      The primary industry that we serve, oil and gas exploration and
production, is a cyclical industry and remains volatile, resulting in
potentially large fluctuations in demand for our Offshore Oil and Gas business,
which could result in significant changes in our revenues and profits.


      We operate primarily as a services company under dayrate contracts.
However, we also own certain specialized capital assets which, if not fully
utilized, could have a negative effect on cash resources as a result of
continuing fixed operating costs and reduced revenues.

      We conduct a significant part of our operations outside the United States.
For the years ended March 31, 2000, 1999 and 1998, foreign operations accounted
for 50%, 48% and 51% of our consolidated revenues, respectively.

                                       7
<PAGE>   8
      Foreign operations are subject to additional political and economic
uncertainties, including the possibility of repudiation of contracts and
confiscation of property, fluctuations in currency exchange rates, limitations
on repatriation of earnings and foreign exchange controls. Certain of the
countries in which we operate have enacted exchange controls to regulate foreign
currency exchange. Exchange controls in some of the countries in which we
operate provide for conversion of local currency into foreign currency for
payment of debts, equipment rentals, technology transfer, technical assistance
and other fees or repatriation of capital. Transfers of profits and dividends
can be restricted or limited by exchange controls. Typically, we are able to
limit the currency risks by arranging compensation in United States dollars or
freely convertible currency and, to the extent possible, limiting acceptance of
blocked currency to amounts which match our expense requirements in local
currencies.

EMPLOYEES

As of March 31, 2000, we had approximately 3,200 employees. Our workforce varies
seasonally and peaks during the summer months. Approximately 7% 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 years ended March 31 2000, 1999 and 1998.

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, described 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, the 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, the United Arab Emirates 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 units Ocean Producer and San Jacinto are supported
through our regional offices in Aberdeen and Singapore, respectively. Operations
of the Ocean Legend will be supported from our office in Perth, Australia that
we opened in 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 such 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 March 31, 2000, we
had working capital of $53 million. Additionally, we had $102 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 $53 million for 2000 compared to $59 million and $45 million for 1999 and
1998, respectively.


      Working capital was $53 million at the end of 2000 compared to $41 million
at the end of 1999 and $45 million at the end of 1998.

      Capital expenditures for the years ended March 31, 2000, 1999 and 1998
were $81 million, $102 million and $94 million, respectively. Capital
expenditures in 2000 consisted of construction costs for our second multiservice
vessel, additions to our ROV fleet and the start of the conversion of a jackup
drilling rig to a mobile offshore production unit for initial use offshore
Western Australia under a three-year contract. Capital expenditures in 1999
consisted of additions to our ROV fleet, construction costs for two MSVs, 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.

      Capital expenditures in 1998 consisted of additions to our ROV fleet,
construction costs for the two multiservice vessels in progress, the purchase of
a production barge operating in Southeast Asia, a tanker for possible future
conversion to production systems use, two out-of-service offshore rigs for
potential conversion to production systems or alternative service and
expenditures on leasehold improvements related to the relocation and
consolidation of some of our office and workshop facilities in the U.S.

      Commitments for capital expenditures at the close of 2000 were
approximately $65 million for completion of the mobile offshore production unit
and $5 million for completion of our second multiservice vessel.


      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 March 31, 2000, at a total cost of $40 million.


      At March 31, 2000, we had long-term debt of $128 million, which equated to
a 40% 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 to repay the then outstanding indebtedness under our prior revolving
credit facility, which had been incurred in the funding of capital expenditures
and treasury stock purchases. In October 1998, we replaced that revolving credit
agreement with a new five-year $80 million revolving credit facility under which
we had $28 million in outstanding borrowings and $52 million available for
future borrowings at March 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. Our debt to total capitalization ratio will vary from
time to time depending primarily upon our level of capital spending.


      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. However, due to the weakness in certain Asian
currencies during 1998, we recognized $1.0 million of losses as Other Expense.
Cumulative translation adjustments as of March 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".

Results of Operations

Our revenues were $417 million for 2000 compared to $400 million for 1999 and
$358 million for 1998. Our gross margins were $72 million for 2000 compared to
$86 million for 1999 and $75 million for 1998. As a percentage of revenue, gross
margins for the three years were 17%, 21% and 21%, respectively. Our net income
in 2000 was $16.8 million, a decrease of 35% from our net income of $25.7
million in 1999, which was 17% higher than the $22 million we reported for 1998.

      Information on our business segments is shown in Note 6 of the Notes to
Consolidated Financial Statements included in this report.

OFFSHORE OIL AND GAS. Revenues for our Offshore Oil and Gas business for 2000
were $294 million compared to $301 million in 1999 and $272 million in 1998. The
income from operations ("Operating Income") from this business for 2000
decreased to $20.0 million compared to $35.9 million in 1999 and $25.2 million
in 1998.

      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 2000, we decided to sell our West Africa diving and related vessel
assets to focus on the growing deepwater service and specialty hardware markets
in this area which have potential for higher margins. In 1997, we decided to
discontinue offering diving services in the North Sea. Based on a review of
actual and expected operating results, we concluded that we would generate
greater returns by focusing on other business lines in the North Sea area. In
March 1997 we entered into an agreement to sell our North Sea diving assets,
including a diving support vessel. The sale closed in April 1997 and the sales
proceeds approximated the net book value of the assets sold. We continue to
provide diving services in other areas.

</TABLE>

      In 2000, ROV revenues declined 6% 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 higher utilization and better results starting in the second half of
our Fiscal 2001. In 1999, ROV revenues increased 20% over 1998 due to the
increase in the number of units.

      Subsea Products revenues were down 4% in 2000 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 an improved umbilical market in
2001 from increased subsea completion activity. In 1999, Subsea Products
revenues were up 22% over 1998 due to better market conditions for umbilical
sales; margins were also higher from improved utilization of plants and better
pricing.


      Mobile Offshore Production Systems 2000 revenues were 24% lower than 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. The Zafiro Producer modification project
contributed to the higher margin percentage in 1999 as compared to 1998. We
anticipate 2001 to be relatively flat compared to 2000, with improved results
the following year when the Ocean Legend commences operations.


                                       13
<PAGE>   14

      Other Services revenues were up 10% in 2000 from 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. Other Services revenues were relatively flat in
1999 compared to 1998. Slightly higher margins reflected better market
conditions.

      We anticipate improved revenues and margins in 2001 for our Offshore Oil
and Gas business from the continued expansion of the ROV fleet and an increased
contribution from the multiservice vessel Ocean Intervention, which we placed in
service in November 1998, and the Ocean Intervention II, which will be placed in
service in the second quarter of 2001.

</TABLE>


      Advanced Technologies revenues in 2000 were 24% higher than in 1999 due to
increased work levels for the Navy, an outfall job in Southeast Asia and more
search and recovery work. Margin percentages were relatively unchanged.


      Revenues for this segment in 1999 increased from 1998 due to higher
activity in subsea telecommunications cable services and the design and assembly
of large, dynamic, animated figures for theme parks. Margins for this segment in
1999 declined due to lower profitability from search and recovery projects and
space-related product and service activities.


      We anticipate lower revenues from this segment in the next fiscal year
based on the transfer of our subsea telecommunications cable activity to a joint
venture.


OTHER. Interest expense increased over the three year period as a result of our
increased borrowings to fund capital expenditures. Interest expense is net of
capitalized interest of $1.8 million for 2000, $2.5 million for 1999 and
$800,000 for 1998.

      Our effective tax rate, determined after consideration of valuation
allowances, foreign, state and local taxes, was 36%, 38% and 38% in 2000, 1999
and 1998, 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.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
our directors, executive officers and persons who own more than 10% of our
Common Stock to file with the SEC and the New York Stock Exchange initial
reports of ownership and reports of changes in ownership of Common Stock. Based
solely on a review of the copies of such reports furnished to us and
representations that no other reports were required, we believe that all our
directors and executive officers complied on a timely basis with all applicable
filing requirements under Section 16(a) of the Exchange Act during the fiscal
year ended March 31, 2000, except that John R. Huff, T. Jay Collins, Marvin J.
Migura, Bruce L. Crager, George R. Haubenreich, Jr., M. Kevin McEvoy and John L.

(2)   In fiscal years 1999 and 1998, Messrs. Huff, Collins, Migura and
      Haubenreich elected to receive all or part of their bonus awards in
      restricted stock. Mr. Crager made the same election in fiscal year 1999.
      The bonus amounts stated for fiscal years 1999 and 1998 include the
      following restricted stock grants valued on the basis of the closing
      market prices of $16.56 and $17.94 per share on the date of award: Mr.
      Huff - 14,188 and 11,148 shares, Mr. Collins - 8,392 and 7,804 shares, Mr.
      Migura - 2,400 and 1,200 shares, Mr. Haubenreich - 1,200 and 3,344, and in
      fiscal year 1999, Mr. Crager - 3,620 shares. Twenty-five percent of these
      restricted stock awards vested in June of the calendar year awarded, with
      the remainder vesting over three years from the vesting date, conditional
      upon continued employment. At the time of each vesting, a tax assistance
      payment is made to the award recipients which must be reimbursed to
      Oceaneering if the vested stock related thereto is sold within three years
      after the vesting date.

(3)   See Long-Term Incentive Plans - Awards in Last Fiscal Year and
      Compensation Committee Report on Executive Compensation, Long-Term
      Incentives. At March 31, 2000, the number and value of the long-term
      incentive restricted stock holdings which have not vested (based on the
      closing market price on that date of $18.75 per share) under restricted
      stock awards were as follows: Mr. Huff - 217,500 shares, $4,078,125; Mr.
      Collins - 103,500 shares, $1,940,625; Mr. Migura - 51,750 shares,
      $970,313; Mr. Crager - 46,500 shares, $871,875; and Mr. Haubenreich

      Dividends, if any, are paid on the restricted shares. The value of such
stock for which restrictions were lifted in fiscal years 2000, 1999 and 1998 is
reported in the LTIP payouts column in the table.

(4)   Amounts represent the aggregate value of long-term incentive restricted
      stock for which restrictions were lifted and the associated tax assistance
      payment.

(5)   In fiscal year 1998 the amount represents Oceaneering contributions under
      a nonqualified executive retirement plan, which terminated in fiscal year
      1998. In fiscal years 2000 and 1999, the amounts represent amounts accrued
      for each executive under a successor and nonqualified Supplemental
      Executive Retirement Plan which are subject to vesting over a three year
      period.

No stock option grants were made in the fiscal year 2000 to any executive
officers listed in the Summary Compensation Table. Nonemployee directors are
participants in the shareholder-approved 1999 Incentive Plan. Under this plan,
each nonemployee director of the Company is automatically granted an option to
purchase 10,000 shares of Common Stock on the date the director becomes a
nonemployee director of the Company, 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 granted become fully exercisable six
months following the date of grant.

EXECUTIVE EMPLOYMENT AGREEMENTS AND CHANGE OF CONTROL AGREEMENTS

         Oceaneering has entered into an employment agreement with no expiration
date with John R. Huff, which provides that, in the event of his termination
from Oceaneering for any reason except voluntary resignation or cause, he will
receive compensation equivalent to one year's salary, inclusive of any amounts
payable under a Senior Executive Severance Plan (the "Severance Plan"). The
employment agreement also provides that Oceaneering will provide medical
coverage to Mr. Huff, his spouse and children during his employment with
Oceaneering and, under circumstances, thereafter for life.

         Under the Severance Plan adopted by the Board of Directors in January
1983, and as amended in March 1989, in the event of a change in control of
Oceaneering (as defined in the Severance Plan) followed by termination of
employment within one year thereafter for any reason other than termination as a
consequence of death, disability or retirement, voluntary termination prior to
three months after a change of control, or termination for cause due to
commission of a felony related to employment with Oceaneering, certain key
executives, as determined by the Board of Directors, will receive a payment
equal to 50% of one year's base salary, including bonuses, and all fringe
benefits for six months after termination of employment. In such an event, stock
options and other benefits of the executive will become immediately vested, and
the executive may elect to either exercise his outstanding stock options or
surrender them and be compensated for the difference between the exercise price
and any higher fair market value of the outstanding stock options. The executive
will also receive 25% of the amount of the difference between the exercise price
and any higher fair

                                       17
<PAGE>   18

market value of all stock options exercised or surrendered by the executive
during the three-year period ending with the date of the executive's termination
of employment. The executive officers listed in the Summary Compensation Table
are participants in the Severance Plan.

         In March 1989, Oceaneering also entered into an amended Supplemental
Senior Executive Severance Agreement ("Supplemental Agreement") with Mr. Huff,
which provides that, in the event of a change in control of Oceaneering (as
defined in the Supplemental Agreement) and termination of his employment for any
reason (other than voluntary resignation for nonpermissible reasons or
termination for cause due to commission of a felony related to employment with
Oceaneering), or reduction in the scope of his position or total annual
compensation, or if he is requested to relocate, Mr. Huff may either elect to
receive the benefits under the Severance Plan, as described above, or the
benefits under the Supplemental Agreement. If he elects to receive the
Supplemental Agreement benefits, Mr. Huff will receive a payment equal to three
years' base salary, including bonuses, and all fringe benefits for six months
after termination of employment, and his stock options and other benefits will
become immediately vested. Mr. Huff may elect either to surrender his
outstanding stock options and receive an amount equal to twice the amount of the
difference between the exercise price and any higher fair market value of the
outstanding stock options, or to exercise such stock options and receive the
amount of the difference. He will also receive 100% of the amount of the
difference between the exercise price and the fair market value of all stock
options exercised or surrendered by him during the three-year period ending with
the date of his termination of employment.

LONG-TERM INCENTIVE PLANS AND RETIREMENT PLANS

         Under our 1990, 1996 and 1999 Long-Term Incentive Plans, the
Compensation Committee of our Board of Directors may grant options, stock
appreciation rights, stock and cash awards to employees and other persons
(excluding nonemployee directors) having an important business relationship with
us.

         We have in effect a Retirement Plan and a Supplemental Executive
Retirement Plan. All our employees and our United States subsidiaries who meet
the eligibility requirements may participate in the Retirement Plan. Certain key
management employees and executives, as approved by the Compensation Committee,
are eligible to participate in the Supplemental Executive Retirement Plan, which
was implemented in fiscal year 1998.

         Under the Retirement Plan, each participant directs Oceaneering to
defer between 1% and 16% of the participant's base pay and contribute the
deferred compensation to the Retirement Plan, with such contributions being
invested in shares of Common Stock, mutual funds and guaranteed investments. A
participant's deferred compensation contributed to the plan is fully vested. Our
contributions to this plan become vested to the participant in percentage
increments over a six-year period, commencing with the participant's date of
employment, provided that the participant remains employed by Oceaneering. We
are currently contributing an amount equal to the deferred compensation of each
participant who has elected to invest in Common Stock up to the first 6% of the
participant's base pay and 50% of the deferred compensation of each participant
who has elected to invest in the other investments up to the first 6% of the
participant's base pay. During fiscal year 2000, none of the executive officers
listed in the Summary Compensation Table made contributions to the Retirement
Plan.

         As of each July 1, Oceaneering may establish an amount to be accrued
pursuant to the Supplemental Executive Retirement Plan for the following
12-month period ("Plan Year") as it determines in its discretion and the amounts
accrued may be different for each participant. No separate fund is maintained
for the Supplemental Executive Retirement Plan. Amounts accrued pursuant to the
Supplemental Executive Retirement Plan are adjusted for earnings and losses as
if they were invested in one or more investment vehicles selected by the
participant from those designated as alternatives by the Compensation Committee.
The account balances vest in one-third increments on the close of the first,
second and third years of continuous employment beginning with and including
July 1 of the Plan Year with respect to which they are accrued. The account
balances vest in any event upon ten years of continuous employment after
becoming a participant, the date that the sum of the participants' attained age
and years of participation equal 65, termination of employment by reason of
death or disability or within two years of a change of control, or termination
of the plan. A participant's interest in the plan is generally distributable
upon termination of employment.

         The following table provides information concerning each stock option
exercised during the fiscal year ended March 31, 2000 by each of the name
executive officers and the value of unexercised options held by such officers at
the end of 2000 fiscal year.

(1)   This grant of shares of restricted Common Stock is subject to earning
      requirements on the basis of a percentage change between the price of the
      Common Stock versus the average of the common stock price of a peer group
      over a three-year time period. See Board Compensation Committee Report on
      Executive Compensation. The grantee of such restricted stock is deemed to
      be the record owner during the restriction period and has all rights of a
      stockholder, including the right to vote and receive dividends; provided,
      however, that such grantee does not have the right to transfer such
      restricted stock until the restrictions relating thereto are removed upon
      achievement of the performance goals and vesting requirements.

COMPLIANCE WITH INTERNAL REVENUE CODE SECTION 162(m)

         Section 162(m) of the Internal Revenue Code generally disallows a
deduction to public companies to the extent of excess annual compensation over
one million dollars paid to the Chief Executive Officer or to any of the four
other most highly compensated executive officers, except for qualified
performance-based compensation. Oceaneering had no nondeductible compensation
expense for fiscal year 2000. Oceaneering plans to review this matter as
appropriate and take action as may be necessary to preserve the deductibility of
compensation payments to the extent reasonably practical and consistent with
Oceaneering's compensation objectives.

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 March 31,
2000 and 1999 and the related consolidated statements of income, cash flows and
shareholders' equity for each of the three 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 March 31, 2000 and 1999 and the
results of their operations and their cash flows for each of the three years in
the period ended March 31, 2000, in conformity with accounting principles
generally accepted in the United States.

accounts and transactions have been eliminated.

      Unless the context indicates otherwise, references to years indicate
Oceaneering's fiscal years.

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:

Depreciation and Amortization

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, ten 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. 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.

         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 Long-Lived Assets to Be Disposed
Of." No impairment adjustments were made during the three years ended March 31,
2000.

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 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. Revenues on contracts with a substantial element
of



                                       31


<PAGE>   32
                 OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES


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.
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," which became effective in the third quarter of 1998.

Other Long-term Liabilities

At March 31, 2000 and 1999, Other Long-term Liabilities include $9.3 million and
$8.1 million, respectively, for self-insurance reserves not expected to be paid
out in the following year and $19.1 and $10.1 million, respectively, for
deferred income taxes.

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.

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 $10.5 million, $18.4 million and $14.7 million for 2000, 1999 and
1998, 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 for the years ended March 31, 2000,
1999 and 1998 were as follows:

</TABLE>

      As of March 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 March 31, 2000 and 1999, Oceaneering's worldwide deferred tax assets
and liabilities and related valuation reserves were as follows:

</TABLE>

      Oceaneering's 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, 1997, 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 to
income before income taxes and minority interests, are reconciled to the actual
provisions for income taxes as follows:

</TABLE>


      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 one. 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 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 three agreements 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 March 31, 2000,
Oceaneering had approximately $17 million in letters of credit outstanding under
these agreements.

      Cash interest payments of $7.7 million, $5.7 million and $1.2 million were
made in 2000, 1999 and 1998, respectively. Interest charges of $1.8 million in
2000, $2.5 million in 1999 and $800,000 in 1998 were capitalized as part of
construction in progress.

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 $2,867,000, $2,508,000 and $1,960,000 for the plan years ended December 31,
1999, 1998 and 1997, respectively.

                 OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES


      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 years ended March 31, 2000, 1999 and
1998 were $32,000, $34,000 and $160,000, 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. Expense
related to the prior plan during the year ended March 31, 1998 was $576,000.
Under the new plan, Oceaneering accrues a portion of the participants' 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 years ended March 31, 2000, 1999 and 1998 was $972,000, $980,000
and $668,000, respectively.

Incentive and Stock Option Plans

Oceaneering has in effect shareholder-approved incentive plans.

      Under the 1996 and 1999 Incentive Plans, a total of 1,165,000 and
1,450,000 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) 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 1996 and 1999 Incentive Plans and a similar
shareholder-approved 1990 Incentive Plan (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 are exercisable over a period of five or ten years after the date of
grant or five years after the date of vesting, generally, at the rate of 20% per
year for three years beginning one year after grant and 40% at the end of the
fourth year, or 25% per year for four years beginning one year after grant.

      During 1999 and 2000, the Compensation Committee granted restricted Common
Stock of Oceaneering to certain of its key executives. In 1998, no such
restricted stock grants were made. 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 three- and one-year time periods, respectively. Up to
one-third of the total grant made in 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 1999 may
be similarly 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 March 31, 2000,
none of the grant made in 2000 was earned and the entire grant made in 1999 was
earned. As of March 31, 2000, a total of 763,250 shares of restricted stock was
outstanding under these and former, similar grants, of which 214,250 shares were
earned, subject to vesting requirements. The numbers and weighted average grant
date fair values of restricted stock granted were 549,000 and $17.06,
respectively, during 2000 and 9,000 and $16.83, respectively, during 1999. In
April 1997, June 1998 and June 1999, certain key executives also elected to
receive restricted Common Stock of Oceaneering totaling 44,968, 35,920 and
42,812 shares with grant date fair values of $14.63, $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 1997, 1998 and 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 issued under plans pursuant to APB
Opinion No. 25, 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 and diluted earnings per share for 2000, 1999
and 1998 would have been $15,442,000, $24,735,000 and $21,373,000, respectively,
and $0.67, $1.08 and $0.92, respectively.

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's
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.

5.  COMMITMENTS AND CONTINGENCIES

Lease Commitments

At March 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:

                                                                 (in thousands)

                                                                    -------
                  Total Lease Commitments                           $20,637
                                                                    =======

      Rental expense, which includes hire of vessels, specialized equipment and
real estate rental, was approximately $22 million, $18 million and $19 million
for the years ended March 31, 2000, 1999 and 1998, 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. Each claim
is reviewed with insurance adjusters and specific reserves are established for
all known liabilities. An additional reserve for incidents incurred but not
reported to Oceaneering is established for each year using management estimates
and based on prior experience. Oceaneering's management believes that
Oceaneering has established adequate accruals for 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 the financial position or results of operations of
Oceaneering.

Letters of Credit

Oceaneering had $17 million and $10 million in letters of credit outstanding as
of March 31, 2000 and 1999, respectively, 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 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 approximates 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 $92 million as of March 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.

      Income from operations for each business segment is determined before
interest income or expense, other expense, minority interests and the 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 revenues in 2000,
1999 or 1998.
