                 OCEANEERING INTERNATIONAL, INC. & SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Basis of Presentation and Significant Accounting Policies

      We have prepared these unaudited consolidated financial statements
      pursuant to instructions for the quarterly report on Form 10-Q required to
      be filed with the Securities and Exchange Commission. These financial
      statements do not include all information and footnotes normally included
      in financial statements prepared in accordance with generally accepted
      accounting principles. These financial statements reflect all adjustments
      that we believe are necessary to present fairly our financial position at
      March 31, 2004 and our results of operations and cash flows for the
      periods presented. All such adjustments are of a normal and recurring
      nature. The financial statements should be read in conjunction with the
      consolidated financial statements and related notes included in our annual
      report on Form 10-K for the year ended December 31, 2003. The results for
      interim periods are not necessarily indicative of annual results.

      Use of Estimates

      The preparation of financial statements in conformity with generally
      accepted accounting principles requires us 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 revenue and expense
      during the reporting period. Actual results could differ from those
      estimates.

      Stock-Based Compensation

      We use the intrinsic value method of accounting established by Accounting
      Principles Board Opinion No. 25, Accounting for Stock Issued to Employees,
      to account for our stock-based compensation programs. Accordingly, we do
      not recognize any compensation expense when the exercise price of an
      employee stock option is equal to the market price per share of our common
      stock on the grant date. The following illustrates the pro forma effect on
      net income and earnings per share if we had applied the fair value
      recognition provisions of SFAS No. 123, Accounting for Stock-Based
      Compensation:

      For purposes of these pro forma disclosures, we estimate the fair value of
      each option grant as of the date of grant using a Black-Scholes option
      pricing model. The estimated fair value of the options is amortized to pro
      forma expense over the expected average lives of the options.

      Variable Interest Entities

      In January 2003, the FASB issued FIN No. 46, Consolidation of Variable
      Interest Entities. FIN No. 46 requires a company to consolidate a variable
      interest entity if it is designated as the primary beneficiary of that
      entity. A variable interest entity is generally defined as an entity whose
      equity is insufficient to absorb the expected losses or whose owners lack
      the risk and rewards of ownership. FIN No. 46 is effective for all
      variable interest entities created or modified after January 31, 2003 and
      requires certain disclosures for all variable interest entities. In
      December 2003, the FASB published a revision to FIN No. 46 ("FIN No. 46R")
      to clarify some of the provisions of the Interpretation and to defer the
      effective date of implementation for certain entities created before
      January 31, 2003. Under the guidance of FIN No. 46R, entities that do not
      have interests in structures that are commonly referred to as special
      purpose entities ("SPEs") are required to apply the provisions of the
      Interpretation in financials statements for periods ending after March 14,
      2004. The adoption of the provisions of FIN No. 46 did not have a material
      impact on our consolidated financial position, results of operations or
      liquidity. In December 2003, we purchased a 50% equity interest in Medusa
      Spar LLC for $43.7 million. Medusa Spar LLC owns a 75% interest in a
      production spar platform. Medusa Spar LLC's revenue is derived from
      processing oil and gas production for a fee based on the volumes processed
      ("throughput"). The majority working interest owner of the Medusa field,
      the spar's initial location, has committed to deliver a minimum
      throughput, which we expect will generate sufficient revenue to repay
      Medusa Spar LLC's bank debt. The Medusa Spar LLC financed its acquisition
      of its 75% interest in the production spar platform using approximately
      50% debt and 50% equity from its equity holders. Our maximum exposure to
      loss from our investment in Medusa Spar LLC is our current carrying value
      of $44.7 million. Medusa Spar LLC is a variable interest entity. As we are
      not the primary beneficiary under FIN 46, we are accounting for our
      investment in Medusa Spar LLC under the equity method of accounting. In
      the first quarter of 2004, we recorded $1.1 million of equity earnings of
      unconsolidated affiliates from this investment.

5.    Income Taxes

      During interim periods, we provide for income taxes at our estimated
      annual effective tax rate, using assumptions as to (1) earnings and other
      factors that would affect the tax calculation for the remainder of the
      year and (2) the operations of foreign branches and subsidiaries that are
      subject to local income and withholding taxes.

      We paid cash taxes of $6.9 million and $2.8 million for the three months
      ended March 31, 2004 and 2003, respectively.

6.    Business Segment Information

      We supply a comprehensive range of technical services and specialty
      products to customers in a variety of industries. Our Oil and Gas business
      consists of five business segments: Remotely Operated Vehicles ("ROVs");
      Subsea Products; Subsea Projects; Mobile Offshore Production Systems; and
      Inspection. Our Advanced Technologies business is a separate segment that
      provides project management, engineering services and equipment for
      applications outside the oil and gas industry. Unallocated expenses are
      those not associated with a specific business segment. These consist of
      expenses related to our incentive and deferred compensation plans,
      including restricted stock and bonuses, as well as other general expenses.

      There are no differences in the basis of segmentation or in the basis of
      measurement of segment profit or loss from those used in our consolidated
      financial statements for the year ended December 31, 2003. The following
      summarizes certain financial data by business segment:

8.    Business Acquisition

      In February 2004, we acquired the drill support ROV business of Stolt
      Offshore S.A. for approximately $50 million. This business acquisition is
      being accounted for using the purchase method of accounting, with the
      purchase price being allocated to the assets and liabilities acquired
      based on their fair market values at the date of acquisition. We have made
      the purchase price allocation based on information currently available to
      us and the allocation is subject to change when we obtain final asset and
      liability valuations. The acquisition was not material. As a result, we
      have not included pro forma information in this report. The results of the
      business acquired are included in our consolidated statement of income
      from the date of the acquisition.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

All statements in this quarterly report on Form 10-Q, 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 have referred to under the headings "Business -- Risks and
Insurance" and "Cautionary Statement Concerning Forward-Looking Statements" in
Part I of our annual report on Form 10-K for the year ended December 31, 2003.
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 be correct. Accordingly, evaluation of our future prospects must be made with
caution when relying on forward-looking information.

This section should be read in conjunction with the Management's Discussion and
Analysis included in our annual report on Form 10-K for the year ended December
31, 2003.

Executive Overview

We generate over 80% of our revenue from our services and products provided to
the oil and gas industry. In 2003, we operated in what we considered to be a
difficult market for oilfield services and products in general. These same
market conditions persisted through the first quarter of 2004. Exclusive of a
$1.8 million pre-tax expense for a terminated acquisition effort, our net
results for the three months ended March 31, 2004 would have been consistent
with those achieved in the three-month periods ended March 31, 2003 and December
31, 2003.

We anticipate that our quarterly earnings for the remainder of 2004 will
increase as we are experiencing higher bidding levels for umbilicals within our
Subsea Products business, and we expect that our Inspection segment will have a
seasonal increase. With the closing of the acquisition of the drill support ROV
business of Stolt Offshore S.A. in February 2004, we expect better ROV results
for the remainder of 2004.

Critical Accounting Policies and Estimates

For information about our Critical Accounting Policies and Estimates, please
refer to the discussion in our annual report on Form 10-K for the year ended
December 31, 2003 under the heading "Critical Accounting Policies and Estimates"
in Item 7 - Management's Discussion and Analysis of Financial Condition and
Results of Operation.

Liquidity and Capital Resources

We consider our liquidity and capital resources adequate to support our
operations and capital commitments. At March 31, 2004, we had working capital of
$91 million, including $14 million of cash and cash equivalents. Additionally,
we had $200 million of borrowing capacity available under our revolving credit
facility.

Our capital expenditures were $67 million during the three months ended March
31, 2004, as compared to $38 million during the corresponding period of last
year. Capital expenditures in the current year consisted primarily of the
acquisition of the drill support ROV business of Stolt Offshore S.A. and
expenditures related to our new umbilical facility in Panama City, Florida.
Prior-year capital expenditures consisted primarily of the acquisition of OIS

                                     PAGE 9


International Inspection plc and expenditures relating to the addition of units
to our fleet of ROVs to replace older units we retired.

We had no material commitments for capital expenditures at March 31, 2004.

At March 31, 2004, we had long-term debt of $152 million and a 29% debt-to-total
capitalization ratio. We have $100 million of Senior Notes outstanding, to be
repaid from 2006 through 2010. We have a $250 million revolving credit facility
that expires in January 2008. The revolving credit facility has short-term
interest rates that float with market rates, plus applicable spreads. We have
not guaranteed any debt not reflected on our consolidated balance sheet and do
not have any off balance sheet arrangements as defined by SEC rules.

In the three-month period ended March 31, 2004, our cash and cash equivalents
decreased $4 million. We generated $22 million in cash from operating
activities, used $67 million of cash in investing activities and obtained $41
million of cash from financing activities. The cash used in investing activities
was used primarily for the acquisition of the drill support ROV business of
Stolt Offshore S.A., and the cash obtained from financing activities was used,
along with the cash provided by operating activities, to pay for the capital
expenditures.

Results of Operations

We operate in six business segments. The segments are contained within two
businesses - services and products provided to the oil and gas industry ("Oil
and Gas") and all other services and products ("Advanced Technologies").

Consolidated revenue and margin information is as follows:

We generate a material amount of our consolidated revenue from contracts for
marine services and inspection 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. Revenues in our Mobile Offshore Production Systems, Subsea Products
and Advanced Technologies segments are generally not seasonal.

Our ROV segment gross margins reflect the utilization percentages of the
respective periods. As a result of increased construction support work, which
began during the latter half of 2003 and carried through the first quarter of
2004, the average revenue per day of ROV utilization was higher than the
corresponding period in 2003, and comparable to that of the preceding quarter.
Gross margin per day of utilization during the first quarter of 2004 was
comparable to that of the corresponding period in 2003, and down from the
unusually high levels experienced during the last quarter of 2003. Over the
balance of the year, we anticipate an increase in profitability from our
international operations, particularly due to the February 2004 acquisition of
34 ROVs from Stolt Offshore S.A.

During the quarter ended March 31, 2004, our Subsea Products revenues and gross
margins increased from the corresponding quarter of the prior year and the
preceding quarter. Our outlook for the Subsea Products segment is highly
positive based on the projected growth in subsea wellhead completions and the
level of bid activity we are experiencing. We anticipate this segment's results
will be higher in 2004 as compared to 2003. Our steel tube cabling

                                    PAGE 11


machine in Brazil is now operational, and we expect our Panama City, Florida
facility, with steel tube capability, to be operational during the fourth
quarter of 2004.

For our Subsea Projects segment, we experienced a seasonal decline compared to
the preceding quarter. Our margins were slightly below those achieved in the
corresponding quarter of 2003. The corresponding period of 2003 included
reductions in cost estimates totaling $1.9 million. We adjusted the cost
estimates due to the favorable completion of an installation project and the
settlement of a personal injury claim. We believe that for 2004 our Subsea
Projects segment will have comparable results to 2003.

Our Mobile Offshore Production Systems gross margins were flat for all periods
presented, as our three main assets were working under the same contracts as in
2003. On a gross margin percentage basis, the first three-month period of 2004
was lower than the other periods presented because 2004 revenue was higher as a
result of low-margin project engineering work. We expect margins to continue at
about the same levels through 2004.

Our Inspection revenues and gross margins were relatively flat. Because our
Inspection segment is headquartered in Aberdeen, Scotland, our Inspection
administrative expenses were higher in 2004 compared to the 2003 period,
primarily due to increases of 13%, compared to the corresponding period of 2003,
and 8%, compared to the preceding quarter, in the value of the British Pound
Sterling measured against the U.S. Dollar. We anticipate having higher margin
percentages for this business for the remainder of 2004 from seasonal factors,
and expect 2004 to have slightly better results than 2003.

Advanced Technologies revenues were higher and margins were flat in the first
three months of 2004 as compared to the corresponding period in 2003 from a mix
of services, with improved revenues and margins in our space services division
being partially offset by lower levels of activities from our entertainment
services division. Gross margin was higher than the immediately preceding
quarter from our space services division. We anticipate quarterly results for
the rest of 2004 to be similar to those achieved in the first three months.

UNALLOCATED EXPENSES

Our unallocated expenses, i.e., those not associated with a specific business
segment, within gross margin consist of expenses related to our incentive and
deferred compensation plans, including restricted stock and bonuses, as well as
other general expenses. Our restricted stock expense varies with the market
price of our common stock. Our unallocated expenses within operating income
consist of those within gross margin plus general and administrative expenses
related to corporate functions. The table below sets out our unallocated
expenses for the three-month periods ended March 31, 2004, March 31, 2003 and
December 31, 2003.

In December 2003, we acquired 50% of Medusa Spar LLC, which owns a 75% interest
in the Medusa Spar production platform in the Gulf of Mexico. Medusa Spar LLC
earns revenue on a tariff basis on oil and gas production throughput processed
by the spar from the Medusa field and surrounding dedicated blocks. The increase
in earnings of Medusa Spar LLC resulted from a full quarter of production in
2004, as compared to several days of production in December 2003.

We own 50% of Smit-Oceaneering Cable Systems, L.L.C., which is a
telecommunications cable laying and maintenance venture. Due to the current
condition of the telecommunications market, the venture is currently inactive
and the single vessel owned by the venture is being marketed for oilfield and
other uses. Results for the first three months of 2004 are comparable to the
corresponding period of 2003.

We own 49% of Pro-Dive Oceaneering Co., a venture that operates our ROVs in
Canada.

Interest expense for the three months ended March 31, 2004 increased compared to
the corresponding period in the prior year due to higher debt levels. Our debt
had been incurred to fund business acquisitions, including the ROV drill support
business of Stolt Offshore S.A. in 2004 and OIS International Inspection plc in
2003, additional equipment, including the Ocean Legend, and expansion of our
Subsea Products production capacity. We did not capitalize any interest during
the three months ended March 31, 2004 or March 31, 2003.

The provisions for income taxes were related to U.S. income taxes that we
provided at estimated annual effective rates using assumptions as to earnings
and other factors that would affect the tax calculation for the remainder of the
year and to the operations of foreign branches and subsidiaries that were
subject to local income and withholding taxes. We anticipate our effective tax
rate for 2004 to be 35%.

ITEM 3. 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 the consolidated financial statements
contained in this report and note 3 of notes to consolidated financial
statements contained in our annual report on Form 10-K for the year ended
December 31, 2003 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. Because
we operate in various oil and gas exploration and production regions in the
world, we conduct a portion of our business in currencies

                                    PAGE 13


other than the U.S. dollar. The functional currency for many of our
international operations is the applicable local currency. 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 use the
exchange rates in effect as of the balance sheet date to translate assets and
liabilities as to which the functional currency is the local currency, resulting
in translation adjustments that we reflect as accumulated other comprehensive
income or loss in the shareholders' equity section of our consolidated balance
sheets. We recorded a $1.4 million adjustment to our equity accounts for the
three-month period ended March 31, 2004 to reflect the net impact of the
weakening of the U.S. dollar against various foreign currencies for locations
where the functional currency is not the U.S. dollar.

Our Subsea Products business in Brazil conducts much of its operations in U.S.
dollars, which is its functional currency. We recorded $1.9 million of foreign
currency losses in our consolidated statement of income for 2003 related to our
operations in Brazil. Foreign currency losses were $730,000 and $672,000 for the
three-month periods ended March 31, 2004 and 2003, respectively.

ITEM 4. CONTROLS AND PROCEDURES.

In accordance with Exchange Act Rules 13a-15 and 15d-15, we carried out an
evaluation, under the supervision and with the participation of management,
including our chief executive officer and chief financial officer, of the
effectiveness of our disclosure controls and procedures as of the end of the
period covered by this report. Based on that evaluation, our chief executive
officer and chief financial officer concluded that our disclosure controls and
procedures were effective as of March 31, 2004 to provide reasonable assurance
that information required to be disclosed in our reports filed or submitted
under the Exchange Act is recorded, processed, summarized and reported within
the time periods specified in the Securities and Exchange Commission's rules and
forms.

There has been no change in our internal control over financial reporting that
occurred during the three months ended March 31, 2004 that has materially
affected, or is reasonably likely to materially affect, our internal control
over financial reporting.
