PART I

ITEMS 1 AND 2. BUSINESS AND PROPERTIES

GENERAL

Tidewater Inc. (the "company") was incorporated in Delaware in 1956. The
company's principal executive offices are located at 1440 Canal Street, New
Orleans, Louisiana 70112, and its telephone number is (504) 568-1010. Unless
otherwise required by the context, the term "company" as used herein refers to
Tidewater Inc. and its consolidated subsidiaries.

The company provides services and equipment to the offshore energy industry
through the operation of the world's largest fleet of offshore service vessels.
The company's compression division, which was sold on February 20, 1998, owned
and operated one of the largest rental fleets of natural gas compressors in the
United States. Please refer to Note 2 of Notes to Consolidated Financial
Statements for further discussion of the sale of Compression operations.

On May 16, 1997 the company acquired all of the shares of O.I.L. Ltd.
(O.I.L.) in exchange for a cash payment of 328 million pounds sterling, or
approximately $534 million. In addition, a 9 million pound sterling, or
approximately $14.4 million, payment was made for the net working capital of
O.I.L. Available cash of $48.4 million and borrowings of $500 million were used
to fund the purchase. Prior to the purchase O.I.L. was principally engaged in
the business of operating approximately 100 marine vessels, primarily platform
supply and anchor handling towing-supply vessels, in several offshore oil and
gas exploration areas outside of the United States. On June 30, 1997 the
company acquired the remaining 50% equity interest in nine towing-supply and
supply vessels previously owned and operated by joint-venture companies in
Australia for a cash payment of $13.2 million and issuance of debt totaling
$14.0 million. Please refer to Note 3 of Notes to Consolidated Financial
Statements for further discussion of the purchases of O.I.L. Ltd. and the
Australian equity interest.

FORWARD LOOKING INFORMATION

In accordance with the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995, the company notes that certain statements set
forth in Items 1 and 7 and elsewhere in this report, which provide other than
historical information and which are forward looking, involve risks and
uncertainties that may impact the company's actual results of operations. The
company faces many risks and uncertainties, many of which are beyond the control
of the company, including fluctuations in oil and gas prices; changes in capital
spending by customers in the energy industry for exploration, development and
production; unsettled political conditions, civil unrest and governmental
actions, especially in higher risk countries of operations; foreign currency
controls and environmental and labor laws. Other risk factors are discussed
elsewhere in this Form 10-K. Readers should consider all of these risk factors,
as well as other information contained in this report.


MARINE OPERATIONS


The company is the world's largest provider of offshore supply vessels and
marine support services serving the energy industry. With a fleet of
approximately 700 vessels, the company operates, and has a leading market
share, in most of the world's significant oil and gas exploration and production
markets and provides services supporting all phases of offshore exploration,
development and production, including: towing of and anchor-handling of mobile
drilling rigs and equipment; transporting supplies and personnel necessary to
sustain drilling, workover and production activities; and supporting pipelaying
and other offshore construction activities.

-3-
The company's fleet is deployed in the major offshore oil and gas areas of
the world. The principal areas of the company's operations include the U.S. Gulf
of Mexico, areas offshore Australia, Brazil, Egypt, India, Indonesia, Malaysia,
Mexico, Trinidad, Venezuela and West Africa and in the North Sea and the Persian
Gulf. The company conducts its operations through wholly-owned subsidiaries and
joint ventures. Information concerning revenues and operating profit derived
from domestic and international marine operations and domestic and international
marine identifiable assets for each of the fiscal years ended March 31 are

Please refer to Item 7 of this report and Note 11 of Notes to Consolidated
Financial Statements for further discussion of revenues, operating profit and
identifiable assets.


Marine Vessel Operations. The company's vessels regularly and routinely move
from one operating area to another, often to and from offshore operating areas
of different continents. Tables comparing the average size of the company's
marine fleet by class and geographic distribution for the last three fiscal
years are included in Item 7 of this report.

The company's largest class of vessels consists of towing-supply and supply
vessels that are chartered to customers for use in transporting supplies and
equipment from shore bases to offshore drilling rigs, platforms and other
installations. In addition, vessels of the towing-supply class are equipped for
and are capable of towing drilling rigs and other marine equipment and setting
anchors for positioning and mooring drilling rigs.

The company's other major classes of vessels include crew and utility vessels
that are chartered to customers for use in transporting small quantities of
supplies and personnel from shore bases to offshore drilling rigs, platforms and
other installations; offshore tugs that tow floating drilling rigs, dock
tankers, tow barges, assist pipelaying and construction barges and are used in a
variety of other commercial towing operations, including towing barges carrying
a variety of bulk cargoes and containerized cargo; and safety/standby vessels
which provide fire fighting and rescue services.

The company's vessels also include inshore tugs; inshore barges; offshore
barges; and production, line-handling and various other special purpose vessels.
Inshore tugs, which are operated principally within inland waters, tow drilling
rigs to and from their locations, and tow barges carrying equipment and
materials for use principally in inland waters for drilling and production
operations. Barges are either used in conjunction with company tugs or are
chartered to others.

-4-
Contributions of Main Classes of Vessels.  Revenues from  vessel operations
were derived from the main classes of vessels in the following percentages:

Year Ended March 31,
--------------------
1998 1997 1996
---- ---- ----
Towing-supply/Supply.. 75.7% 70.2% 72.8%
Offshore Tugs......... 11.9% 15.3% 16.6%
Crew/Utility.......... 6.3% 6.5% 7.8%
Safety/Standby........ 4.6% 5.3% --
Other................. 1.5% 2.7% 2.8%
---- ---- ----

Shipyards. Quality Shipyards, Inc., a wholly-owned subsidiary of the
company, operates two shipyards in Houma, Louisiana, which construct, modify and
repair vessels. Approximately 71% of the shipyards' business for the year ended
March 31, 1998 related to repairs and modifications of the company's vessels.

Risks of Operation and Insurance. The operation of any marine vessel
involves an inherent risk of catastrophic marine disaster, adverse weather
conditions, mechanical failure, collisions, property losses to the vessel and
business interruption due to political action in countries other than the United
States. Any such event may result in a reduction in revenues or increased
costs. The company's vessels are insured for their estimated market value
against damage or loss, including war and pollution risks. The company also
carries workers' compensation, maritime employer's liability, general liability
(including third party pollution) and other insurance customary in the industry.

The company's international marine vessel operations are subject to the usual
risks inherent in doing business in countries other than the United States.
Such risks include political changes, possible vessel seizure, company
nationalization or other governmental actions, currency restrictions and
revaluations, and import/export restrictions, all of which are beyond the
control of the company. Although it is impossible to predict the likelihood of
such occurrences or their effect on the company, the company believes these
risks to be within acceptable limits and, in view of the mobile nature of the
company's principal revenue producing assets, does not consider them to
constitute a factor materially adverse to the conduct of its international
marine vessel operations as a whole.

Industry Conditions, Competition and Customers. The company's operations are
materially dependent upon the levels of activity in offshore oil and natural gas
exploration, development and production throughout the world. Such activity
levels are affected both by short-term and long-term trends in world oil and
natural gas prices. Given the recent drop in the price of oil coupled with the
announcement during fiscal 1998 of new vessel building programs by competitors,
management is concerned that an overcapacity of vessels in the U.S. Gulf of
Mexico market could occur and could result in weakened demand for the company's
services during fiscal 1999. Should demand for the company's services in the
U.S. Gulf of Mexico weaken during fiscal 1999, the results of the company's
domestic operations would be adversely affected.

The principal competitive factors for the offshore vessel service industry
are suitability and availability of equipment, price and quality of service.
The company has numerous competitors in virtually all areas in which it
operates. Certain customers of the company own and operate vessels to service
certain of their offshore activities.

The company's diverse, mobile asset base and geographic distribution allow it
to respond to changes in market conditions and provide a broad range of vessel
services to its customers throughout the world. Management believes that the
company has a significant competitive advantage because of the size, diversity
and geographic distribution of its vessel fleet, the company's financial
condition and economies of scale.

Although one customer accounted for 11% and the five largest customers
accounted for approximately

-5-
28% of its revenues during the year ended March 31, 1998, the company does not
consider its operations dependent on any single customer.

Government Regulations. The company's vessels are subject to various
statutes and regulations governing their operation and maintenance.

Under the Merchant Marine Act of 1936 and the Shipping Act, 1916, the company
would lose the privilege of engaging in U.S. coastwise trade if more than 25% of
the company's outstanding stock was owned by non-U.S. citizens. The company has
a dual stock certificate system to prevent non-U.S. citizens from owning more
than 25% of its common stock. In addition, the company's charter permits the
company certain remedies with respect to any transfer or purported transfer of
shares of the company's common stock that would result in the ownership by non-
U.S. citizens of more than 24% of its common stock. Based on information
supplied to the company by its transfer agent, approximately 2.5% of the
company's outstanding common stock was owned by non-U.S. citizens as of March
31, 1998.

At March 31, 1998, 330 vessels wholly owned by the company were registered
under flags other than the United States. In addition, most of the company's 36
joint venture owned vessels were registered under non-U.S. flags at March 31,
1998. The laws of the United States provide that once a vessel is registered
under a flag other than the United States, it cannot thereafter engage in U.S.
coastwise trade. Therefore, the company's non-U.S. flag vessels must continue
to be operated abroad, and if the company were not able to secure charters
abroad for them, and work would otherwise have been available for them in the
United States, its operations would be adversely affected.

All of the company's offshore vessels are subject to international safety and
classification standards. U.S. flag towing-supply and supply vessels are
required to undergo periodic inspections and to be recertified under drydock
examination at least twice every five years. Non-U.S. flag vessels are also
subject to similar regulations.


SEASONALITY

The company's vessel fleet generally has its highest utilization rates in the
warmer temperature months when the weather is more favorable for offshore
exploration, development and construction work. However, business volume for
the company is more dependent on oil and natural gas prices and the global
supply and demand conditions for the company's services than any seasonal
variation.


ENVIRONMENTAL COMPLIANCE

Compliance with existing governmental regulations which have been enacted or
adopted regulating the discharge of materials into the environment, or otherwise
relating to the protection of the environment, has not had, nor is expected to
have, a material effect on the company.


EMPLOYEES

As of March 31, 1998, the company had approximately 8,500 employees. The
company considers relations with employees to be satisfactory. The company is
not a party to any union contract in the United States but through several
subsidiaries is a party to union agreements covering local nationals in several
countries other than the United States.


ITEM 3. LEGAL PROCEEDINGS

The company is not a party to any litigation which, in the opinion of
management, is likely to have a material adverse effect on the company's
financial position or results of operations. Please refer to Item 7 and Note 10
of Notes to Consolidated Financial Statements for further discussion of these
matters.

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

The company provides services and equipment to the international offshore
energy industry through the operation of a diversified fleet of marine service
vessels. Revenues, net earnings and cash flows from operations are dependent
upon the activity level of the vessel fleet which is ultimately dependent upon
oil and natural gas prices which, in turn, are determined by the supply/demand
relationship for oil and natural gas. The following discussion should be read
in conjunction with the Selected Financial Data and the Consolidated Financial
Statements and related disclosures.

BUSINESS OVERVIEW

During the quarter ended June 30, 1997 the company acquired all of the shares
of O.I.L. Ltd. (O.I.L.) in exchange for a cash payment of 328 million pounds
sterling, or approximately $534 million. In addition a 9 million pound
sterling, or approximately $14.4 million, payment was made for the net working
capital of O.I.L. Available cash of $48.4 million and borrowings of $500 million
were used to fund the purchase. Prior to the purchase O.I.L. was principally
engaged in the business of operating approximately 100 marine vessels, primarily
platform supply and anchor handling towing-supply vessels, in several offshore
oil and gas exploration areas outside of the United States. The total cost of
the acquisition of $626 million, which includes $65.6 million of deferred income
tax liability, was allocated under the purchase method of accounting based on
the fair value of the assets acquired and liabilities assumed plus amounts for
professional fees, severance and other transaction costs and the related
deferred tax effect of the acquisition. Goodwill of approximately $355 million
has been recorded in the Consolidated Balance Sheet.

The $500 million of debt incurred to finance the O.I.L. acquisition was
borrowed pursuant to a $600 million Revolving Credit and Term Loan agreement
with several banks and consists of a $400 million term loan and $100 million
borrowed under the $200 million revolving credit facility of the agreement. As
of March 31, 1998 all debt borrowed for the O.I.L. acquisition had been repaid
and the $400 million term loan facility was canceled.

On June 30, 1997 the company acquired the remaining 50% equity interest in
nine towing-supply and supply vessels previously owned and operated by joint-
venture companies in Australia for a cash payment of $13.2 million and issuance
of debt totaling $14.0 million. The debt has been discounted to yield interest
at 7% and is to be repaid in semi-annual installments. The total estimated cost
of the acquisition of $30 million was allocated under the purchase method of
accounting based on the fair value of the assets acquired and liabilities
assumed, plus amounts for professional fees, severance and other transaction
costs and the related deferred tax effect of the acquisition. Goodwill of
approximately $12 million has been recorded in the Consolidated Balance Sheet.

On February 20, 1998 the company completed the sale of its compression
division. In consideration of the sale, the company received cash of
approximately $348 million; $326 million of which was used to retire the then
remaining balance of debt borrowed for the O.I.L. acquisition.

During fiscal 1997 the company purchased for $12.4 million in cash the
remaining equity interests in 22 of 29 safety/standby vessels previously owned
and operated by joint-venture companies in the North Sea. The acquisition of
these vessels was accounted for using the purchase method.

-9-
In fiscal 1996 the company expanded its domestic operations by merging with
Hornbeck Offshore Services, Inc. (Hornbeck). Hornbeck's fleet consisted of 61
towing-supply and supply vessels operating in the U.S. Gulf of Mexico and an
equity interest in 29 safety/standby vessels operating in the North Sea. The
merger was accounted for as a pooling-of-interests and accordingly, the
consolidated financial statements and the related disclosures and the selected
financial data for fiscal 1996 and prior years were restated to include the
operations of Hornbeck.

Improved market conditions for company services during fiscal 1998 and an
expanded international vessel fleet pushed operating performance above the prior
year level as fiscal 1998 earnings from continuing operations climbed 71% above
the preceding fiscal year's amount. The improvement in fiscal 1998 earnings
from continuing operations was after eliminating the effects of unusual items in
both fiscal 1998 and fiscal 1997. Fiscal 1998 earnings from continuing
operations included a $5.3 million, or $.09 per common share, after-tax
provision for possible litigation expenses, a $.8 million, or $.01 per common
share, after-tax gain from the settlement of obligations resulting from the
fiscal 1996 curtailment of the company's pension plan and a $7.3 million, or
$.12 per common share, reduction in income tax expense. The reduction in income
tax expense consisted of a $4 million reduction of deferred income taxes
resulting from the lowering of United Kingdom corporate income tax rates and a
$3.3 million reduction in a previously established liability for outstanding
U.S. income tax issues. Fiscal 1997 earnings from continuing operations
included an after-tax charge of $1.9 million, or $.03 per common share, to
establish a provision for possible losses resulting from one of the company's
insurers filing for liquidation. Future operating performance should remain
positive given the near-term outlook for services provided by the company both
domestically and internationally. However, long-term domestic operations
performance could be adversely affected if significant building of new supply
vessels continues and the resulting supply/demand relationship for company
services weakens.

MARINE OPERATIONS

Fleet size, utilization and vessel day rates primarily determine the amount of
revenues and operating profit because operating costs and depreciation do not
change proportionally when revenue changes. Operating costs primarily consist
of crew costs, repair and maintenance, insurance, fuel, lube oil and supplies.
Fleet size and utilization are the major factors which affect crew costs. The
timing and amount of repair and maintenance costs are influenced by vessel age
and scheduled drydockings to satisfy safety and inspection requirements mandated
by regulatory agencies. Whenever possible, vessel drydockings are done during
seasonally slow periods to minimize any impact on vessel operations and are only
done if economically justified, given the vessel's age and physical condition.
The following table compares revenues and operating expenses (excluding general
and administrative expenses and depreciation expense) for the company's vessel
fleet for the years ended March 31:

The significant growth in fiscal 1998 operating profit compared with the
preceding fiscal year resulted from higher average day rates for the worldwide
vessel fleet, a larger international-based vessel fleet and higher gains from
assets sales, partially offset by higher operating costs. Higher average day
rates for the worldwide vessel fleet resulted from a more favorable
supply/demand relationship for company services both in the U.S. Gulf of Mexico
and internationally. Higher fiscal 1998 operating costs resulted from the
expansion of the international-based vessel fleet through the purchase of the
O.I.L. and Australian vessels, increased costs associated with attracting,
training and retaining qualified vessel personnel and a greater number of vessel
drydockings. Higher gains on asset sales in fiscal 1998 resulted from the
disposal of several vessels, most of which had previously been withdrawn from
active service due to obsolescence and prohibitive repair costs.

The substantial growth in fiscal 1997 operating profit above the prior year
level was the result of higher utilization of the worldwide fleet, a larger
international-based fleet and significantly higher day rates for the domestic-
based fleet partially offset by higher operating expenses. Higher utilization
of the worldwide fleet in fiscal 1997 is attributable to greater demand for
offshore marine services. A larger international-based fleet is the result of
the fiscal 1997 first quarter purchase of the remaining 50.1% equity interest in
several safety/standby vessels previously operated by joint-venture companies in
the North Sea. Significantly higher day rates for the domestic-based fleet is
the result of a much more favorable supply/demand relationship for offshore
marine services in the U.S. Gulf of Mexico. Fiscal 1997 operating expenses rose
above fiscal 1996's amount due to the expansion of the North Sea fleet,
increased costs associated with attracting, training and retaining vessel
personnel, higher activity for the domestic-based offshore towing fleet, and a
greater number of vessel drydockings.

Marine fleet utilization is determined primarily by market conditions and to
a lesser extent by drydocking requirements. Utilization of the domestic-based
fleet, which operates in U.S. waters, is primarily influenced by offshore
activity related to the exploration, development and production of natural gas
in the U.S. Gulf of Mexico; whereas, utilization of the international-based
fleet, which operates in waters other than the United States, is primarily
influenced by offshore activity related to the exploration, development and
production of oil. Vessel day rates are determined by the demand created
through the level of offshore exploration, development and production spending
by energy exploration and production companies relative to the supply of
offshore service vessels. Suitability of equipment and the degree of service
provided also influence vessel day rates. The following tables compare day-
based Marine fleet utilization percentages and average day rates by vessel class
and in total for each of the quarters in the years ended March 31:

The drop in the average size of the worldwide fleet from fiscal 1996 to
fiscal 1997 is the result of the return of previously leased vessels to their
owners and the disposition of obsolete vessels. From fiscal 1997 to fiscal 1998
the net increase in the average number of vessels is the result of the addition
of O.I.L. vessels and the disposition of obsolete vessels.


CORPORATE

Earnings from continuing operations before income taxes for the company
consists of the following items for the years ended March 31:


(In thousands) 1998 1997 1996
- -------------- ---------- -------- --------
Marine operating profit $393,987 212,404 118,909

-------- ------- -------
Earnings from continuing operations
before income taxes $356,468 204,074 100,028
======== ======= =======

Fiscal 1998 other expense of $6.8 million consists of an $8 million provision
for possible litigation costs which could result from certain alleged labor-law
pay violations in various areas of the world where marine vessel operations are
conducted, and a $1.2 million gain from the settlement of obligations resulting
from the fiscal 1996 curtailment of the company's pension plan.

Other expense for fiscal 1997 is a charge for possible losses resulting from
one of the company's insurers filing for liquidation. Fiscal 1996 other expense
consisted of $9.6 million of costs resulting from the merger with Hornbeck
Offshore Services, Inc. and a $3.0 million charge as a result of the removal of
fleet personnel from the company's defined benefit pension plan. On April 1,
1996 these employees, along with all new employees of the company who are
eligible for pension plan membership, were enrolled in a new defined
contribution retirement plan.

------- ------ ------
$72,926 53,850 48,840
======= ====== ======

Higher fiscal 1998 general and administrative expenses are the result of the
O.I.L. and Australian acquisitions and higher costs associated with incentive
bonus and restricted stock plans.


LIQUIDITY, CAPITAL RESOURCES AND OTHER MATTERS

The company's current ratio, level of working capital and amount of cash
flows from continuing operations for any year are directly related to fleet
activity and vessel day rates. Fleet activity and vessel day rates are
ultimately determined by the supply/demand relationship for oil and natural gas.
Variations from year-to-year in these items are primarily the result of market
conditions. Cash from ongoing operations in combination with available lines of
credit provide the company, in management's opinion, with adequate resources to
satisfy financing requirements. At March 31, 1998, $175 million of the
company's $200 million revolving line of credit was available to satisfy
financing needs. Continued payment of dividends, currently $.15 per quarter per
common share, is subject to declaration by the Board of Directors.

Excluding the sale of compression operations and the O.I.L. and Australian
acquisition, fiscal 1998 investing activities consumed more cash than in prior
years as a result of the increased level of additional investments in the fleet.
Additional investments in the fleet included $20.2 million for the purchase of
six safety/standby vessels, two towing-supply/supply vessels, a utility vessel
and a crewboat. The remaining amount invested in the fleet during fiscal 1998
was for additions and/or modifications to existing vessels to meet customer
requirements.

Fiscal 1998 financing activities consumed less cash than in prior years.
Fiscal 1998 principal payments on long-term debt included $34.1 million of
scheduled payments, $477.4 million of prepayments on the credit facility and the
repayment of $14.8 million of debt assumed from the O.I.L. and Australian
acquisitions. The company purchased 1,481,000 shares of common stock during the
quarter ended March 31, 1998 at an average cost per share of $44.01 including
broker commissions and fees.


YEAR 2000

In fiscal 1997 the company began modifying its existing software applications
to be year 2000 compliant. As of the end of fiscal 1998, the company is still
reviewing and modifying all affected software applications, including the
computerized operating systems of company vessels. The company expects this
process to be complete well in advance of year 2000 with the costs of such
modifications being immaterial with respect to the company's results of
operations and financial position.


NEW ACCOUNTING PRONOUNCEMENTS

During fiscal 1998 the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards (SFAS) No. 130, "Reporting Comprehensive
Income," SFAS No. 131, "Disclosure about Segments of an Enterprise and Related
Information" and SFAS No. 132, "Employer's Disclosures about Pension and Other
Postretirement Benefits." The additional disclosure requirements of each of
these SFAS's are effective during the company's fiscal year ending March 31,
1999. Management believes the adoption of these pronouncements will result in
additional financial statement disclosures only and will not have a material
impact on its fiscal 1999 consolidated financial statements.

-15-
CURRENCY FLUCTUATIONS AND INFLATION

Because of its significant international operations, the company is exposed
to currency fluctuations and exchange risk. To minimize the financial impact of
these items the company attempts to contract a majority of its services in
United States dollars.

Day-to-day operating costs are generally affected by inflation. However,
because the energy services industry requires specialized goods and services,
general economic inflationary trends may not affect the company's operating
costs. The major impact on operating costs is the level of offshore
exploration, development and production spending by energy exploration and
production companies. As this spending increases, prices of goods and services
used by the energy industry and the energy services industry will increase.
Future improvements in vessel day rates may shield the company from the
inflationary effects on operating costs.


ENVIRONMENTAL MATTERS

During the ordinary course of business the company's operations are subject
to a wide variety of environmental laws and regulations. The company attempts
to comply with these laws and regulations in order to avoid costly accidents and
related environmental damage. Compliance with existing governmental regulations
which have been enacted or adopted regulating the discharge of materials into
the environment, or otherwise relating to the protection of the environment, has
not had, nor is expected to have, a material effect on the company.

REPORTS OF INDEPENDENT AUDITORS




The Board of Directors and Shareholders
Tidewater Inc.



We have audited the accompanying consolidated balance sheet of Tidewater Inc. as
of March 31, 1998 and the related consolidated statements of earnings,
stockholders' equity, and cash flows for the year then ended. Our audit also
included the financial statement schedule listed in the accompanying Index to
Financial Statements and Schedule for the year ended March 31, 1998. These
financial statements and schedule are the responsibility of the company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audit. The consolidated financial
statements and schedule of Tidewater Inc. as of March 31, 1997, and for each of
the two years in the period ended March 31, 1997, were audited by other auditors
whose report dated April 30, 1997, expressed an unqualified opinion on those
statements and schedule.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the 1998 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Tidewater Inc.
at March 31, 1998 and the consolidated results of its operations and cash flows
for the year then ended in conformity with generally accepted accounting

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- ------------------------------------------
March 31, 1998, 1997 and 1996

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

The company provides services and equipment to the offshore energy industry
through the operation of the world's largest fleet of offshore service vessels.
Revenues, net earnings and cash flows from operations are dependent upon the
activity level for the vessel fleet which is ultimately dependent upon oil and
natural gas prices which, in turn, are determined by the supply/demand
relationship for oil and natural gas.

USE OF ESTIMATES

In preparing the company's financial statements, management makes informed
estimates and assumptions that affect the amounts reported in the financial
statements and related disclosures. Actual results may differ from these
estimates.

PRINCIPLES OF CONSOLIDATION

The Consolidated Financial Statements include the accounts of Tidewater Inc.
and its subsidiaries. Significant intercompany balances and transactions are
eliminated in consolidation.

PROPERTIES AND EQUIPMENT

Properties and equipment are carried at cost. Depreciation for financial
reporting purposes is computed primarily on the straight-line basis beginning
with the first charter/rental, with salvage values of 5%-10% for marine
equipment, using estimated useful lives of:


Years
-------
Marine equipment (from date of construction) 15 - 25
Other properties and equipment 3 - 30


Used equipment is depreciated in accordance with the above schedule; however,
no life less than six years is used for marine equipment regardless of the date
constructed.

Maintenance and repairs are charged to operations as incurred during the
asset's original estimated useful life. Major repair costs incurred after the
original estimated useful life that also have the effect of extending the useful
life of the asset are capitalized and amortized over three years. Major
modifications to equipment are capitalized and amortized over the remaining life
of the equipment.

GOODWILL

Goodwill primarily relates to the O.I.L. acquisition made during fiscal 1998
and is being amortized over 40 years. Management periodically reviews goodwill
to access recoverability, and impairments would be recognized in operating
results if a permanent diminution in value were to occur.


ACCRUED PROPERTY AND LIABILITY LOSSES

The company's insurance subsidiary establishes case based reserves for
estimates of reported losses on direct business written, estimates received from
ceding reinsurers, and reserves based on past experience of unreported losses.
Such losses principally relate to the company's marine operations and are
included as a component of costs of marine operations in the Consolidated
Statements of Earnings. The liability for such losses and the related
reimbursement receivable from reinsurance companies are classified in the
Consolidated Balance Sheet into current and noncurrent amounts based upon
estimates of when the liabilities will be settled and when the receivables will
be collected.

F-8
PENSION AND OTHER POSTRETIREMENT BENEFITS

Pension costs are accounted for in accordance with the provisions of
Statement of Financial Accounting Standards (SFAS) No. 87 and are funded to meet
the minimum funding requirements as required by law. Prior service costs are
amortized on the straight-line basis over the average remaining service period
of employees expected to receive pension benefits. Postretirement benefits
other than pensions are accounted for in accordance with SFAS No. 106. The
estimated cost of postretirement benefits other than pensions are accrued during
the employees' active service period.


INCOME TAXES

Income taxes are accounted for in accordance with the provisions of SFAS No.
109. Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.


EARNINGS PER SHARE

Earnings per share are computed in accordance with SFAS No. 128. SFAS No.
128 requires the replacement of previously reported primary and fully diluted
earnings per share required by Accounting Principles Board Opinion No. 15 with
earnings per share and diluted earnings per share. The calculation of earnings
per share excludes any dilutive effect of stock options, while diluted earnings
per share includes the dilutive effect of stock options. Per share amounts for
all periods presented have been restated to conform to the requirements of SFAS
No. 128. Per share amounts disclosed in these Notes to Consolidated Financial
Statements are on a diluted basis.


FOREIGN CURRENCY TRANSLATION

Assets and liabilities of international operations, other than international
operations in highly inflationary economies, are translated into U.S. dollars
using current exchange rates in effect at the balance sheet date and for revenue
and expense accounts using weighted average exchange rates during the period.
Adjustments resulting from the balance sheet account translations, net of
deferred income taxes, are included in stockholders' equity as foreign currency
translation adjustments.


CASH EQUIVALENTS

For purposes of the Consolidated Statements of Cash Flows the company
considers all highly liquid investments with maturities of three months or less
when purchased to be cash equivalents.


REVENUE RECOGNITION

Marine services are generally contracted for on a rate per day of service
basis; therefore, marine vessel revenues are recognized on a daily basis
throughout the contract period.


CONCENTRATIONS OF CREDIT RISK

Financial instruments which potentially subject the company to concentrations
of credit risk consist principally of trade and other receivables. These
receivables are with a variety of domestic, international and national energy
companies and also include reinsurance companies for recoverable insurance
losses. The company manages its exposure to risk through ongoing credit
evaluations of its customers and generally does not require collateral. The
company maintains an allowance for doubtful accounts for potential losses and
does not believe it is exposed to concentrations of credit risk that are likely
to have a material impact on the company's financial position or results of
operations.


STOCK-BASED COMPENSATION

The company uses the intrinsic value method of accounting for stock-based
compensation prescribed by Accounting Principles Board Opinion No. 25 and,
accordingly, adopted the disclosure provisions of SFAS No. 123.


NEW ACCOUNTING PRONOUNCEMENTS

During fiscal 1998 the Financial Accounting Standards Board issued SFAS No.
130, "Reporting

F-9
Comprehensive Income," SFAS No. 131, "Disclosure about Segments of an Enterprise
and Related Information" and SFAS No. 132, "Employer's Disclosures about Pension
and Other Postretirement Benefits." The additional disclosure requirements of
each of these SFAS's are effective during the company's fiscal year ending March
31, 1999. Management believes the adoption of these pronouncements will result
in additional financial statement disclosure only and will not have a material
impact on its fiscal 1999 consolidated financial statements.


RECLASSIFICATIONS

Certain amounts from prior years have been reclassified to conform with
current year classifications.


(2) BUSINESS DISPOSITION

On February 20, 1998 the company completed the sale of its compression
division. The compression division provided natural gas and air compression
equipment and services, principally to the energy industry. In consideration of
the sale the company received cash of approximately $348 million. Accordingly,
the company's consolidated financial statements for all periods have been
reclassified to report separately financial position, results of operations, and
operating cash flows from continuing operations and the discontinued compression

(3) BUSINESS COMBINATIONS

On May 16, 1997 the company acquired all of the shares of O.I.L. Ltd.
(O.I.L.) in exchange for a cash payment of 328 million pounds sterling, or
approximately $534 million. In addition a 9 million pound sterling, or
approximately $14.4 million, payment was made for the net working capital of
O.I.L. Available cash of $48.4 million and borrowings of $500 million were used
to fund the purchase. Prior to the purchase O.I.L. was principally engaged in
the business of operating approximately 100 marine vessels, primarily platform
supply and anchor handling towing-supply vessels, in several offshore oil and
gas exploration areas outside of the United States. The total cost of the
acquisition of $626 million, which includes $65.6 million of deferred income tax
liability, was allocated under the purchase method of accounting based on the
fair value of the assets acquired and liabilities assumed, plus amounts for
professional fees, severance and other transaction costs and the related
deferred tax effect of the

F-10
acquisition.

The results of O.I.L.'s operations have been consolidated with the company's
effective May 16, 1997. Pro forma combined results of continuing operations of
the company and of O.I.L. including appropriate purchase accounting adjustments
for the years ended March 31, 1998 and 1997 as though the acquisition had taken
place on April 1 of the respective fiscal years are as follows:

Diluted earnings per share.. $ 5.17 2.21
</TABLE>

The $500 million of debt incurred to finance the O.I.L.. acquisition was
borrowed pursuant to a $600 million Revolving Credit and Term Loan agreement
with several banks and consisted of a $400 million term loan and $100 million
borrowed under the $200 million revolving credit facility of the agreement. At
March 31, 1998 all debt borrowed to finance the O.I.L. acquisition had been
repaid and the $400 million term loan facility canceled.

On June 30, 1997 the company acquired the remaining 50% equity interest in
nine towing-supply and supply vessels previously owned and operated by joint-
venture companies in Australia for a cash payment of $13.2 million and issuance
of debt totaling $14.0 million. The debt has been discounted to yield interest
at 7% and is to be repaid in semi-annual installments. The total estimated cost
of the acquisition of $30 million was allocated under the purchase method of
accounting based on the fair value of the assets acquired and liabilities
assumed, plus amounts for professional fees, severance and other transaction
costs and the related deferred tax effect of the acquisition.


On May 31, 1996 the company acquired for $12.4 million cash the remaining
50.1% equity interest in 22 of 29 safety/standby vessels previously owned and
operated by joint-venture companies in the North Sea. At the same time the
company granted to the seller a call option on its 49.9% equity interest in the
remaining seven safety/standby vessels for 1 pound sterling, which option was
exercised during fiscal 1998. The acquisition was accounted for by the purchase
method and accordingly, the fair value of the assets acquired and liabilities
assumed and results of operations have been included in the consolidated
financial statements effective June 1, 1996.

On March 13, 1996 Tidewater Inc. issued 8,475,214 shares of its common stock
in exchange for all of the outstanding common stock of Hornbeck Offshore
Services, Inc. (Hornbeck). Hornbeck owned and operated a fleet of 61 marine
service vessels operating in the U.S. Gulf of Mexico and had a 49.9% interest in
29 safety/standby vessels operating in the North Sea. This business combination
has been accounted for as a pooling-of-interests and, accordingly, the
consolidated financial statements for periods prior to the combination have been
restated to include the accounts and results of operations of Hornbeck. Fiscal
1996 merger expenses of $9.6 million, which are classified as other expense in
the Consolidated Statements of Earnings, include legal, investment banking and
accounting fees, severance and other costs related to the business combination
with Hornbeck.

The reversal of taxes overaccrued in prior years is the result of the
company's settlement in the fourth quarter of fiscal 1998 of open income tax
audits with the Internal Revenue Service for fiscal years 1993, 1994 and 1995.

The significant components of deferred income tax expense for the years ended
March 31 are as follows:

========= ========
</TABLE>

The net changes in the valuation allowance for the years ended March 31, 1998
and 1997 were an increase of $14.8 million and a decrease of $3.2 million,
respectively. The additional fiscal 1998 valuation allowance is a result of
increased doubt over the ultimate realization of benefits from certain foreign
net operating losses. The remaining balance of the deferred tax assets is
expected to be realized through future operating results and the reversal of
taxable temporary differences.

The company has not recognized a deferred tax liability of approximately
$31.5 million for the undistributed earnings of certain non-U.S. subsidiaries
that arose in prior years because the company currently does not expect those
unremitted earnings to reverse and become taxable to the company in the
foreseeable future. A deferred tax liability will be recognized when the
company expects that it will realize those undistributed earnings in a taxable
manner, such as through receipt of dividends or sale of

F-13
investments. As of March 31, 1998, the undistributed earnings of these
subsidiaries were approximately $90 million.


(6) LONG-TERM DEBT

At March 31, 1998, the company has a $200 million revolving credit facility
with a group of banks and at that date there were $25 million of borrowings
under the facility. Borrowings bear interest, at the company's option, at prime
or Federal Funds rates plus .5% or Eurodollar rates plus margins from .5% to 1%
based on the company's debt to capitalization ratio. The revolving credit
commitment expires on April 30, 1999, at which time the then outstanding balance
will convert to a term loan repayable in 16 quarterly installments beginning
July 31, 1999. All of the borrowings under the agreement are unsecured and the
company pays an annual fee of .25% on the unused portion of the facility.

Under the terms of the agreement, the company has agreed to limitations on
future levels of investments and aggregate indebtedness, a minimum level of
tangible net worth and maintenance of certain debt to capitalization ratios.
The agreement also prohibits the company from encumbering its assets, other than
assets already encumbered at March 19, 1997 for the benefit of others.

Current maturities of long-term debt at March 31, 1998 of $6.5 million
consist of the remaining debt associated with the Australian joint-ventures'
acquisition made during fiscal 1998.


(7) BENEFIT PLANS

Upon meeting various citizenship, age and service requirements, employees are
eligible to participate in a defined contribution savings plan and can
contribute from 2% to 15% of their base salary to an employee benefit trust.
The company matches with company common stock 50% of the employee's contribution
to the plan up to a maximum of 6% of the employee's base salary. The plan held
487,571 shares and 510,772 shares of the company's common stock at March 31,
1998 and 1997, respectively. Amounts charged to expense for the plan for 1998,
1997 and 1996 were $1.8 million, $1.7 million and $1.0 million, respectively.

A defined benefit pension plan covers certain U.S. citizen employees and
employees who are permanent residents of the United States. Benefits are based
on years of service and employee compensation. The company's policy is to fund
the plan based upon minimum funding requirements of the Employee Retirement
Income Security Act of 1974. The company also has a supplemental retirement
plan (Supplemental Plan) that provides pension benefits to certain employees in
excess of those allowed under the company's tax-qualified pension plan. Certain
benefits programs are maintained in several other countries which provide
retirement income for covered employees.

Net periodic pension cost for the U.S. defined benefit pension plan and the
Supplemental Plan for 1998, 1997 and 1996 include the following components:

During the fourth quarter of fiscal 1996 the company recorded as other
expense an estimated curtailment charge of $3 million as a result of the removal
of fleet personnel from the company's U.S. defined benefit pension plan. During
the third quarter of fiscal 1998, the obligations related to the curtailment of
the plan were settled and a gain on settlement of $1.2 million was recorded as
other income. Beginning April 1, 1996 these employees removed from this defined
benefit pension plan, along with all new employees of the company who are
eligible for pension plan membership, were enrolled in a new defined
contribution retirement plan. This plan is noncontributory by the employee, but
the company contributes in cash 3% of an eligible employee's compensation to an
employee benefit trust. The cost of the plan for fiscal 1998 and 1997 was $2.7
million and $2.3 million, respectively.

During the fourth quarter of fiscal 1998, as a result of the sale of the
company's compression division, the company recorded as part of the gain on sale
of discontinued compression operations a pre-tax curtailment gain of $2.4
million resulting from the removal of all compression personnel from the U.S.
defined benefit pension plan, the Supplemental Retirement Plan and the post-
retirement health care and life insurance plan.

Qualified retired employees currently are covered by a program which provides
limited health care and life insurance benefits. Costs of the program are based
on actuarially determined amounts and are accrued over the period from the date
of hire to the full eligibility date of employees who are expected to qualify
for these benefits. This plan is not funded.

Net periodic postretirement health care and life insurance costs for 1998,
1997 and 1996 include the following components:

The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation will be 7% in 1999, gradually declining to 4%
in the year 2005 and thereafter. A 1% change in the assumed health care cost
trend rates for each year would change the accumulated postretirement benefit
obligation by approximately $1.7 million at March 31, 1998 and change the cost
for the year ended March 31, 1998 by $.4 million. The assumed discount rate
used in determining the accumulated postretirement benefit obligation was 7.5%
in 1998 and 1997.

(9) CAPITAL STOCK

At March 31, 1998 and 1997, 125 million shares of $.10 par value common stock
were authorized and 59,482,769 shares and 60,334,889 shares were issued and
outstanding, respectively. At March 31, 1998 and 1997, three million shares of
no par value preferred stock were authorized and unissued.

Under the company's stock option and restricted stock plans, the Compensation
Committee of the Board of Directors has authority to grant stock options and
restricted shares of the company's stock to officers and other key employees. At
March 31, 1998, 4,423,105 shares of common stock are reserved for issuance under
the plans of which 2,451,500 shares are available for future grants. Stock
options are granted with an exercise price equal to the stock's fair market
value at the date of grant. All stock options have ten-year terms and most of
the outstanding options vest and become exercisable in equal installments over a
three-year period from the grant date.

The per share weighted-average fair values of stock options granted during
fiscal years 1998, 1997 and

F-16
1996 were $17.69, $15.46 and $13.38, respectively, on the dates of grant using
the Black Scholes option-pricing model with the following weighted-average
assumptions:

</TABLE>

The company applies APB Opinion No. 25 in accounting for its plans and,
accordingly, no compensation cost has been recognized for its stock options in
the consolidated financial statements. Had the company determined compensation
cost based on the fair value at the grant date for its stock options under SFAS
No. 123, the company's net earnings would have been reduced to the pro forma
amounts as follows:

</TABLE>

Pro forma net earnings and diluted earnings per common share reflect only
options granted during fiscal years 1998, 1997 and 1996. Therefore, the full
impact of calculating compensation cost for stock options under SFAS No. 123 is
not reflected in the pro forma amounts presented above because compensation cost
is reflected over the options' vesting period of three years and compensation
cost for options granted prior to April 1, 1995 is not considered.

At March 31, 1998, 1997 and 1996, the number of options exercisable under the
stock option plans was

F-17
865,383, 940,579 and 771,125, respectively; and the weighted average exercise
price of those options was $28.47, $21.51 and $17.43, respectively.

In March 1998, 36,500 shares of restricted common stock of the company were
granted to certain key employees. These restricted shares vest and become
freely transferable over a four-year period provided the employee remains
employed by the company during the vesting period. During the restricted
period, the restricted shares may not be transferred or encumbered, but the
recipient has the right to vote and receive dividends on the restricted shares.
The fair market value of the stock at the time of grant totaled approximately
$1.6 million and was classified in stockholders' equity as deferred compensation
restricted stock. The deferred amount is being amortized by equal monthly
charges to earnings over the four-year vesting period.

In accordance with a June 13, 1994 employment agreement with the company's
chairman of the board, 70,000 shares of restricted common stock of the company
were granted to him on October 20, 1994. The restricted stock agreement
contained provisions for vesting of the shares at varying intervals when the
average market price of the common stock reaches certain predetermined levels.
During the years ended March 31, 1998, 1997 and 1996, 20,000, 25,000 and 25,000
shares, respectively, vested due to the attainment of the three price levels
applicable to those shares. The fair market value of the stock at the time of
grant totaling approximately $1.6 million was classified in stockholders' equity
as deferred compensation restricted stock. As a result of the vesting of the
70,000 shares over the last three fiscal years, by March 31, 1998 the total
deferred amount had been charged to earnings.

In accordance with a new employment agreement with the company's chairman of
the board entered into on September 25, 1997, 50,000 shares of restricted common
stock were granted on that date. These restricted shares also vest at varying
intervals when the average market price of the common stock reaches certain
predetermined levels. The fair market value of the stock at the time of grant
totaling approximately $3 million was deferred and is being amortized by equal
monthly charges to earnings over five years.

During the third quarter of fiscal 1997 the Board of Directors authorized a
share repurchase program whereby the company could purchase in the open market
or through privately negotiated transactions up to $200 million of company
common stock through March 31, 1998. The company expended during fiscal 1998
and 1997 a total of $150 million for the purchase of 3,269,100 common shares at
an average cost of $45.88 per share, including broker commissions and fees.
Fiscal 1998 purchases totaled $65.2 million for 1,481,000 shares and fiscal 1997
purchases totaled $84.8 million for 1,788,100 shares.

During the fourth quarter of fiscal 1998 the Board of Directors authorized a
new share repurchase program whereby the company may purchase up to an
additional $200 million of company common stock through March 31, 1999. No
shares had been purchased under this program as of March 31, 1998.

Under a Shareholder Rights Plan, one preferred stock purchase right has been
distributed as a dividend for each outstanding common share. Each right
entitles the holder to purchase, under certain conditions, one one-hundredth of
a share of Series A Participating Preferred Stock at an exercise price of $160,
subject to adjustment. The rights will not be exercisable unless a person (as
defined in the plan) acquires beneficial ownership of 15% or more of the
outstanding common shares, or a person commences a tender offer or exchange
offer, which upon its consummation such person would beneficially own 15% or
more of the outstanding common shares. The Board of Directors is authorized in
certain circumstances to lower the beneficial ownership percentage to not less
than 10%.

If after the rights become exercisable a person becomes the beneficial owner
of 15% or more of the outstanding common shares (except pursuant to an offer for
all shares approved by the Board of Directors), each holder (other than the
acquirer) will be entitled to receive, upon exercise, common shares having a
market value of twice the exercise price. In addition, if the company is
involved in a merger (other than a merger which follows an offer for all shares
approved by the Board of Directors), major sale of assets or other business
combination after a person becomes the beneficial owner of 15% or more of the
outstanding common shares, each holder of a right (other than the acquirer) will
be entitled to receive, upon exercise, common stock of the acquiring company
having a market value of twice the exercise price.

F-18
The rights may be redeemed for $.01 per right at any time prior to ten days
following the acquisition by a person of 15% or more of the outstanding common
shares. The rights expire on November 1, 2006.


(10) COMMITMENTS AND CONTINGENCIES

An employment agreement exists with the company's chairman of the board
whereby he will serve in such capacity as well as president and chief executive
officer through September 19, 2000. The terms of the employment agreement
provide for an annual base salary and certain other benefits. Compensation
continuation agreements exist with all other officers of Tidewater Inc. whereby
each receives compensation and benefits in the event that their employment is
terminated following certain events relating to a change in control of the
company. The maximum amount of compensation that could be paid under the
agreements, based on present salary levels, is approximately $10.2 million. The
amount that could be paid for certain benefits is not presently determinable.

During fiscal 1997 the Internal Revenue Service (IRS) notified the company of
proposed deficiencies aggregating approximately $17.5 million of additional
income taxes resulting from audits of the company's income tax returns for the
years ended March 31, 1993, 1994 and 1995. During the fourth quarter of fiscal
1998 the company and the IRS settled all outstanding issues regarding these
audits with no additional taxes due. As a result of the settlement, the company
reduced previously provided for income taxes in the amount of $3.3 million.

The company is the defendant to several alleged labor-law pay violations
claimed by certain current and former employees in various areas of the world
where its marine vessel operations are conducted. During the fourth quarter of
fiscal 1998 the company entered into an agreement to settle a majority of these
claims, although such settlement is subject to court approval and other
conditions. During the third quarter of fiscal 1998, the company provided $8
million for the possible adverse outcome of these labor-law matters. In
management's opinion, the amount of the company's liability in excess of amounts
provided in the financial statements for these labor-law matters, if any, will
not have a material adverse effect on the company's financial position or the
results of its ongoing operations.

During the fourth quarter of fiscal 1997 the company recorded as other
expense a charge of $2.8 million ($1.9 million after tax, or $.03 per common
share) to establish a provision for loss resulting from one of the company's
insurers filing for liquidation.

Various legal proceedings and claims are outstanding which arose in the
ordinary course of business. In the opinion of management, the amount of
ultimate liability, if any, with respect to these actions will not have a
materially adverse effect on the company's financial position or results of its
ongoing operations.

(A) One marine customer accounted for 11%, 11% and 12% of revenues for the
fiscal years ended March 31, 1998, 1997 and 1996, respectively.

(B) Marine support services are conducted worldwide with assets that are highly
mobile. Revenues and identifiable assets attributable to these operations
in any one country are not "significant" as that term is defined by SFAS No.
14. Further, most identifiable assets in each country are comprised of
offshore service vessels, which regularly and routinely move from one
operating area to another, often to and from offshore operating areas of
different continents. Equity in net assets of non-U.S. subsidiaries is
$795.1 million, $211.5 million and $148.0 million at March 31, 1998, 1997
and 1996, respectively. Other international identifiable assets include
accounts receivable and other balances denominated in currencies other than
the U.S. dollar which aggregate approximately $19.1 million, $6.7 million
and $8.5 million at March 31, 1998, 1997 and 1996, respectively. These
amounts are subject to the usual risks of fluctuating exchange rates and
government-imposed exchange controls.
