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's two principal divisions are Tidewater Marine and Tidewater
Compression.  Tidewater Marine provides support services to the international
offshore petroleum industry.  Tidewater Compression provides natural gas
compression equipment and services, primarily to the energy industry.

      Information concerning revenues, operating profits and assets for each of
the company's divisions and the geographic distribution of its operations is
set forth in Item 7 of this report.

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.

TIDEWATER MARINE

      Tidewater Marine is the world's largest provider of offshore supply
vessels and marine support services.  With a fleet of approximately 600
vessels, Tidewater Marine operates, and has a leading market share, in most of
the world's significant oil and gas exploration and production markets.
Tidewater Marine 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.

      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.  For information concerning revenues derived
from domestic and international marine operations, see "Marine Division" in
Item 7 of this report.

      Marine Services Equipment.  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





                                      -3-
<PAGE>   4
comparing the average number of vessels in the company's marine fleet by class
and geographic distribution appear under "Marine Division" 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 classes of vessels include crew and utility vessels
that are chartered to customers for use in transporting supplies and personnel
from shore bases to offshore drilling rigs, platforms and other installations,
and 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.

      The company's vessels also include inshore tugs and both inshore and
offshore barges, production, line-handling and various 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 water drilling and production
operations.  Barges are either used in conjunction with company tugs or are
chartered to others.

      Information concerning the average age of the company's Marine vessel
fleet is set forth in Item 7 of this report.

      On March 20, 1997 the company agreed to purchase for approximately $535
million O.I.L. Ltd.  O.I.L. Ltd. is a subsidiary of Ocean Group plc, of the
United Kingdom, and owns a fleet of approximately 100 vessels, principally
composed of towing-supply and supply vessels operating in most major offshore
oil and gas exploration areas other than the United States.  Final
determination of the purchase price is subject to certain conditions to be
satisfied at closing.  The acquisition will be accounted for using the purchase
method and will be financed under a $600 million credit facility.  The purchase
agreement calls for the closing to be no later than May 30, 1997, unless
extended by both parties.

      In March 1996 the company acquired a fleet of 61 vessels owned and
operated by Hornbeck Offshore Services, Inc.  ("Hornbeck") and it also acquired
Hornbeck's 49.9% interest in 29 safety/standby vessels operating in the North
Sea.  In fiscal 1997 the company acquired for $12.4 million cash the remaining
equity interests in 22 of the 29 safety/standby vessels previously owned by
certain North Sea joint-venture companies. Information concerning these
acquisitions appears in Note 2 of Notes to Consolidated Financial Statements
included in this report. In addition, in fiscal 1997 the company acquired eight
used vessels, consisting of four towing-supply and supply vessels, two offshore
tugs and two crewboats.

      Contributions of Main Classes of Vessels.  Of the company's revenues from
marine vessel equipment operations, the following percentages were contributed
by the main classes of vessels:

      Shipyards.  Quality Shipyards, Inc., a wholly-owned subsidiary of the
company, operates two shipyards in Houma, Louisiana, which construct, modify,
repair and drydock vessels.  Approximately 76% of the shipyards' business for
the year ended March 31, 1997 related to repairs, modifications and drydockings
of the company's vessels.

      Risks of Operation and Insurance.  The operation of any marine equipment
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 equipment 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 equipment operations as a whole.

      Industry Conditions, Competition and Customers.  Tidewater Marine'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.  In recent years, oil and natural gas prices
and, therefore, the level of offshore drilling and exploration activity, have
been extremely volatile.  A discussion of current market conditions appears
under "Business Overview" in Item 7 of this report.

      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.

      Tidewater Marine's diverse, mobile asset base and geographic distribution
allow it to respond quickly to 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 fleet, the company's financial
condition and economies of scale.

      Although one customer accounted for 11% and the five largest customers
accounted for approximately 30% of its marine revenues during the year ended
March 31, 1997, the company does not consider its marine 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 trades 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.





                                      -5-
<PAGE>   6
Based on information supplied to the company by its transfer agent,
approximately 3% of the company's outstanding common stock was owned by
non-U.S. citizens as of March 31, 1997.

      At March 31, 1997, 204 vessels wholly owned by the company were
registered under flags other than the United States.  In addition, all of the
company's 47 joint venture owned vessels were registered under non-U.S. flags
at March 31, 1997.  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 various similar regulations.

TIDEWATER COMPRESSION

      Tidewater Compression provides natural gas and air compression equipment
and services to the energy industry, primarily in the United States.

      Gas Compression Rentals.  The company rents natural gas compressors to
oil and gas producers and processors.  With a fleet of approximately 2,800
compressors, Tidewater Compression operates one of the largest rental fleets of
gas compressors in the United States.  The compressors are used primarily to
boost the pressure of natural gas from the wellhead into gas gathering systems,
into nearby gas processing plants, or into high pressure pipelines.  Gas
compression equipment and services offered by the company also are used in the
production of coalbed methane and in enhanced recovery projects such as
fire-flooding, gas lift, or gas injection, with the objective of increasing the
amount of oil or condensate that can be recovered from a reservoir.  Customers
often rent compressors rather than purchase them because the required
compressor horsepower and stage configuration can change several times in the
lifetime of a project.  The primary market served is natural gas production
activities in the United States, although the company has modest operations in
Australia, Argentina, Venezuela and Canada.  A table setting forth utilization,
rental rates and fleet size of the Tidewater Compression natural gas compressor
rental fleet appears in "Compression Division" in Item 7 of this report.

      Equipment and Parts Sales.  Tidewater Compression's Tide Air & Gas
division sells natural gas and air compressor packages and other related
equipment to domestic and international engineering contractors, oil and gas
producers and to manufacturers and other concerns.  The equipment consists of
skid mounted compressors designed to meet complex specifications for
specialized applications.  The gas compression equipment is used to facilitate
the production, transportation and storage of natural gas as well as boosting
fuel gas pressure for electrical power generation.  The air compression
equipment is used to operate machinery, for instrumentation and in
manufacturing processes.  The company's compression operations include an
engineering and fabrication facility at which the company designs and
constructs natural gas and air compression packages.

      Distributorships.  The company holds distributorships for various
manufacturers of natural gas and air compressors, related equipment and a wide
range of accessories.  These manufacturers are the source for equipment and
accessories sold by the company.

      Industry Conditions.  In addition to well age and natural gas
consumption, a structural shift in U.S. onshore oil and gas industry operations
is affecting demand for natural gas compression package rentals.  Many of the
major oil companies have directed their focus toward international operations
and away from





                                      -6-
<PAGE>   7
domestic onshore natural gas reserves.  Accordingly, these companies recently
have been selling their domestic onshore natural gas reserves and minimizing
staff in domestic operations.  As a result, demand for rental packages of
natural gas compressors is expected to increase as buyers of natural gas
reserves or producers with reduced staffs are less likely to own and operate
natural gas compressor packages and more likely to rent natural gas compressor
packages to meet their natural gas compression needs.

      Competition and Customers.  The compression equipment market is highly
competitive, with the principal competitive factors being price, quality of
service and availability.  The company competes with a large number of
companies in each area in which it operates.

      Although one customer accounted for 7.5% and the five largest customers
accounted for approximately 21% of its compression revenues during the year
ended March 31, 1997, the company does not consider itself dependent on any one
customer.

      International Operations.  While most of Tidewater Compression's
operations are domestic, the company sells and rents natural gas compressor
packages and parts in Canada and rents natural gas compressors in Australia,
Argentina and Venezuela.  The Tide Air & Gas division's natural gas and air
compression packages are sold to customers worldwide.

SEASONALITY

      Tidewater Marine generally has its highest utilization rates in the
warmer temperature months when the weather is more favorable for offshore
exploration, development and construction work.  Tidewater Compression
generally has its best results in the winter months when natural gas is in
greater demand.  However, business volume for both Tidewater Marine and
Tidewater Compression is more dependent on oil and 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 has 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.

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

          The company provides services and equipment to the energy  industry
through its Marine and Compression divisions.  Company revenues, net earnings
and cash flows from operations are dependent upon activity levels of the Marine
vessel fleet and the Compression natural gas rental fleet.  Activity levels for
the Marine vessel fleet and the Compression natural gas rental fleet are
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

          On March 20, 1997 the company agreed to purchase, for approximately
$535 million, O.I.L. Ltd.  O.I.L. Ltd is a subsidiary of Ocean Group plc, of
the United Kingdom, and owns a fleet of approximately 100 vessels principally
composed of towing-supply and supply vessels operating in most major offshore
oil and gas exploration areas other than the United States.  Final
determination of the purchase price is subject to certain conditions to be
satisfied at closing.  The acquisition will be accounted for using the purchase
method and will be financed under a $600 million credit facility.  The purchase
agreement calls for the closing to be no later than May 30, 1997, unless
extended by both parties.

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

          In March 1996 the company expanded its domestic marine operations
when it merged 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 a 49.9% 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 accounts and the results of operations of Hornbeck.  After-tax
merger costs of $7.8 million, or $.12 per common share, reduced fiscal 1996 net
earnings and consisted of legal, accounting and investment banking fees,
payments under severance and employment agreements, and a provision for certain
other costs related to the merger.

          Better market conditions for the services provided by the company's
marine division in the U.S. Gulf of Mexico and in certain international
locations pushed operating  performance above prior year levels as fiscal 1997
net earnings rose 92% above fiscal 1996's amount.  The growth in fiscal 1997
net earnings was after allowing for unusual items in both fiscal 1997 and
fiscal 1996.  Fiscal 1997 net earnings included an after-tax charge of $1.9
million, or $.03 per common share, to establish reserves for losses resulting
from one of the company's insurers filing for liquidation.  Fiscal 1996 net
earnings included an after-tax charge of $9.8 million, or $.15 per common
share, for $7.8 million of merger costs discussed above and $2.0 million for
the curtailment of the company's pension plan.  Future operating results should
be positively affected as domestically, market conditions for the services
provided by the company's Marine and Compression divisions remain favorable and
a larger and more diversified international-based Marine vessel fleet will
improve the company's ability to satisfy customer demands.

MARINE DIVISION

          The Marine division provides a diverse range of services and
equipment to the offshore energy industry.  Fleet size, utilization and vessel
day rates primarily determine the amount of revenues and





                                      -10-
<PAGE>   11
operating profit because operating costs and depreciation do not change
proportionally with changes in revenues.  Operating costs consist primarily 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 tables compare revenues, operating expenses
(excluding general and administrative expenses and depreciation expense) and
operating margins of the Marine division's owned and operated vessel fleet for
the years ended March 31:

(A)  For fiscal 1997, fiscal 1996 and fiscal 1995 one Marine customer accounted
     for 11%, 12% and 12%, respectively, of Marine revenues.


         The substantial growth in fiscal 1997 operating margins 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.

         Fiscal 1996 operating margins rose above the prior year level due to
higher utilization and average day rates for the worldwide vessel fleet.
Fiscal 1996's operating margins were adversely impacted by a significant
increase in the amount of repair and maintenance expense which primarily
affected the domestic-based vessel fleet.  Approximately 68% of the increase in
repair and maintenance expense in





                                      -11-

fiscal 1996 is attributable to a change in estimated useful lives of marine
vessels, whereby costs which would have been capitalized under the previous
life estimates were expensed.

expense and depreciation expense) and operating margins of brokered vessels,

(A)      Marine equipment operations 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 Statement of Financial Accounting Standards 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 $211,450,000, $148,045,000 and $164,175,000 at March
         31, 1997, 1996 and 1995, respectively. Other  international
         identifiable assets include accounts receivable and other balances
         denominated in currencies other than the U.S. dollar which aggregate
         approximately $6,652,000, $8,520,000 and $7,062,000 at March 31, 1997,
         1996 and 1995, respectively.  These  amounts are subject to the usual
         risks of fluctuating exchange rates and government-imposed exchange
         controls.

         discussion of depreciation policy changes effective in fiscal 1996.

         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.  The following two sets of
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:

   Additional investment in the vessel fleet for fiscal 1997, fiscal 1996 and
fiscal 1995 totaled $40.0 million, $41.0 million and  $100.0 million,
respectively.  In fiscal 1997, eight used vessels were acquired for $18.7
million consisting of four towing-supply/supply vessels, two offshore tugs and
two crewboats.   In fiscal 1996, 28 used vessels were acquired for $28.7
million and consisted of eight towing-supply/supply vessels, eight offshore
tugs, 11 crewboats and a utility vessel.  Fiscal 1995 vessel additions
consisted of 23 supply vessels, two offshore tugs and a crewboat for $64.3
million.  Nineteen and ten of the vessels acquired in fiscal 1996 and fiscal
1995, respectively, were previously operated by the company under various
long-term lease agreements.  The remainder of additions to the vessel fleet of
$21.3 million, $12.3 million and $35.7 million for fiscal 1997, fiscal 1996 and
fiscal 1995, respectively, were for modifications to the existing vessel fleet.
In fiscal 1997's first quarter the remaining 50.1% equity interest in 22 of 29
safety/standby vessels, previously operated by joint-venture companies in the
North Sea, was acquired and increased the size of the international-based
fleet.  In fiscal 1996 and fiscal 1995 these vessels were classified as joint-
venture owned.  The average age of the owned and operated vessel fleet is
approximately 19 years.  The following table compares the average number of
vessels by class and geographic distribution during the years ended March 31:

(A)      Change in number of vessels is the result of the company's acquisition
         of the remaining 50.1% interest in a North Sea joint venture effective
         June 1, 1996.

         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.

COMPRESSION DIVISION

         The Compression division provides natural gas compression services and
equipment for a variety of applications primarily in the energy industry.
Rental revenues are determined, for the most part, by utilization and fleet
size.  Utilization is affected by natural gas storage levels and by the number
and age of producing oil and natural gas wells which, in turn,  are dependent
upon the price levels of oil and natural gas.  Quality of service, availability
and rental rates for equipment are also major factors which affect utilization.
Operating expenses are generally consistent from year-to-year and usually vary
in the short-term due to fluctuations in the amount of repair and maintenance
expense.  Long-term growth in operating expenses will occur primarily as a
result of increased fleet size and general inflationary factors.  Compression
division operating profit is primarily determined by operating margins from
rental gas compression operations.  The following tables compare revenues,
operating expenses (excluding general and administrative expense and
depreciation expense), operating margins and related statistics for natural gas
compression operations for the years ended March 31:

</TABLE>


         Increased competition for natural gas compression services during
fiscal 1997 depressed rental rates below the fiscal 1996 level and outweighed
the positive effect of higher utilization thus adversely affecting fiscal 1997
operating margins.   Fiscal 1997 operating margins were also negatively
affected as repair and maintenance costs climbed above the fiscal 1996 level as
a result of a greater number of compressor overhauls partly caused by the
higher utilization level.  Fiscal 1996 revenues and operating margins rose
above prior year levels as a result of a full year's impact of the expansion of
the natural gas compressor rental fleet which occurred in the third quarter of
fiscal 1995.

         The Compression division also designs, fabricates and installs
engineered compressor systems and sells related parts and equipment.  The
following table compares revenues, costs of sales and gross profit margins for
equipment and parts sales for the years ended March 31:

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

         Fluctuations in the level of equipment and parts sales are due to the
timing of sales of engineered products.  Fluctuations in gross profit margin
percentages are the result of competitive market forces.





                                      -16-
<PAGE>   17
Costs of sales consist primarily of wages and benefits and material costs
associated with the design, fabrication and installation of packaged compressor
systems.

         Additional investment in the natural gas compression rental fleet for
fiscal 1997, fiscal 1996 and fiscal 1995 totaled $ 17.9 million, $5.1 million
and $255.4 million, respectively.  Additions for fiscal 1995 include the
acquisitions of the natural gas compression assets of Halliburton Company for
$205 million and the assets of Brazos Gas Compressing Company for $35 million.
The remainder of additions for fiscal 1995 and the additions for fiscal 1996
and 1997 were for modifications to the existing natural gas compressor rental
fleet and for the construction of additional natural gas compressors.  During
the first quarter of fiscal 1997 the Compression division disposed of all of
its air rental equipment which generated proceeds of $3.5 million and a gain of
$.5 million.  The remainder of gains from the sale of equipment for fiscal 1997
and gains from the sale of equipment for fiscal 1996 and fiscal 1995 were $.7
million, $.4 million and $1.1 million, respectively.

         Identifiable assets and depreciation expense for the years ended March
31 were:

         Other expense for fiscal 1997 is a charge to establish reserves for
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 Marine fleet and Compression field service personnel
from the company's defined benefit  pension plan.  On April 1, 1996 these
Marine and Compression 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.  Fiscal 1995 other expense consisted of a $2.5
million charge for insurance losses as a result of the potential insolvency of
certain of the company's insurers and a $5.9 million charge for the costs of
restructuring the company's corporate headquarters and worldwide marine
operations which was designed to reduce costs and improve operating
efficiencies.

         Fiscal 1997 principal payments of $58.0 million on long-term debt were
primarily for the prepayment of the debt assumed in connection with the
purchase of the remaining equity interests in certain North Sea joint-venture
companies.  Lower interest and other debt costs in fiscal 1997 compared with
the prior year resulted from the fiscal 1996 fourth quarter prepayment of debt
assumed in connection with the merger with Hornbeck Offshore Services, Inc.
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 $84.8 million on the
purchase of 1,788,100 shares at an average cost, including broker commissions
and fees, of $47.42 per share during fiscal 1997.  All shares purchased have
been canceled.

         The Internal Revenue Service has 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.  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.
While the amount, if any, of such claims for which the company ultimately may
be held liable is not presently determinable, if the claimants and all
similarly situated employees and former employees who might file claims were
successful, the aggregate amount of the company's liability, based on available
information, could approximate $15 million.  The company is in the process of
defending against these claims and assessments and, in management's opinion,
the ultimate outcome of these matters will not have a material adverse effect
on the company's financial position or the results of its ongoing operations.

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 and natural gas compressor rental rates
may shield the company from the inflationary effects on operating costs.

INDEPENDENT AUDITORS' REPORT






The Board of Directors and Shareholders of Tidewater Inc.:

We have audited the accompanying consolidated financial statements of Tidewater
Inc. and subsidiaries as listed in the accompanying index. In connection with
our audits of the consolidated financial statements, we also have audited the
financial statement schedule as listed in the accompanying index. These
consolidated financial statements and financial statement schedule are the
responsibility of the company's management. Our responsibility is to express an
opinion on these consolidated financial statements and financial statement
schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Tidewater Inc. and
subsidiaries as of March 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the years in the three-year period ended March
31, 1997, in conformity with generally accepted accounting principles. Also in
our opinion, the related financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
March 31, 1997, 1996 and 1995

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

       The company provides services and equipment to the offshore energy
industry through its marine and compression divisions. The marine division owns
and operates the world's largest fleet of offshore service vessels and the
compression division owns and operates one of the largest rental fleets of
natural gas compressors in the United States. Activity levels for the marine
vessel fleet and compression rental fleet are 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.

BASIS OF CONSOLIDATION

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

INVENTORIES

       Inventories are stated at average cost for operating supplies and at the
lower of cost (FIFO) or market (net realizable value) for merchandise held for
resale.

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 and 30% for compression equipment, using estimated useful lives of:

<TABLE>
<CAPTION>
                                                                         Years
- ------------------------------------------------------------------------------
<S>                                                                     <C>
Marine equipment (from date of construction)                            15 - 25
Compression equipment                                                    8 - 12
Other properties and equipment                                           3 - 30
</TABLE>

       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.

       In fiscal 1996 the estimated useful lives of the company's marine
vessels were increased from 10-20 years to 15-25 years. The increase in useful
lives was made in order to provide a better matching of revenues and
depreciation expense over a vessel's economic useful life. This change in
accounting estimate lowered fiscal 1996 depreciation expense by approximately
$25.2 million. Concurrent with this change approximately $10.2 million of
repair and maintenance costs that would have been capitalized in fiscal 1996
had the previous estimated useful lives been used, was expensed. The change
increased fiscal 1996 net earnings by $10.0 million, or $.16 per common share.

       On April 1, 1996 the company adopted the provisions of Statement of
Financial Accounting Standards (SFAS) No. 121 "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of." The adoption
had no impact on the company's results of operations or financial position.

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.

PENSION AND OTHER POSTRETIREMENT BENEFITS

       Pension costs are accounted for in accordance with the provisions of
Statement of Financial Accounting Standards No. 87 and are funded 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 Statement of Financial Accounting Standards No. 106. The
estimated cost of postretirement benefits other than pensions are accrued
during the employees' active service period. Postemployment and postretirement
benefits other than pensions are funded as claims are submitted.

INCOME TAXES

       Income taxes are accounted for in accordance with the provisions of
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes." 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

       Primary earnings per share are computed based on the weighted average
number of shares and dilutive equivalent shares of common stock (stock options
and restricted stock grants) outstanding during each year using the treasury
stock method.

FOREIGN CURRENCY TRANSLATION

       The functional currency for certain non-U.S. subsidiaries and
unconsolidated companies is the applicable local currency. The translation of
the applicable local currencies into U.S. dollars is performed for balance
sheet accounts 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. The gains and losses resulting from the balance sheet
account translations, net of deferred income taxes, are included in
stockholders' equity.

       Some transactions of the company and its subsidiaries are made in
currencies different from their own. Gains and losses from these transactions
are included in the Consolidated Statements of Earnings as they occur and
relate primarily to the revenue generating and purchasing activities in Brazil,
Venezuela, Mexico, United Kingdom, Singapore, Trinidad and Nigeria.

CASH FLOWS

       For purposes of the Consolidated Statements of Cash Flows, all highly
liquid investments purchased with original maturities of approximately three
months or less are considered to be cash equivalents. Some items of compression
equipment are acquired and placed in inventories for subsequent sale or rent to
others. Acquisitions of these assets are considered operating activities in the
Consolidated Statements of Cash Flows, although they later may be transferred
to the compression equipment rental fleet.

STOCK COMPENSATION

       On April 1, 1996 the company elected to continue to use the intrinsic
value method of accounting for stock-based compensation prescribed by
Accounting Principles Board (APB) Opinion No. 25 and, accordingly, adopted the
disclosure provisions of SFAS No. 123 "Accounting for Stock-based
Compensation."

NEW ACCOUNTING PRONOUNCEMENTS

       The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards (SFAS) No. 128, "Earnings per Share" and SFAS No. 129,
"Disclosure of Information about Capital Structure." SFAS No. 128 is effective
for annual and interim periods ending after December 15, 1997. SFAS No. 129 is
effective for fiscal years ending after December 15, 1997. Management does not
believe that these pronouncements will have a material impact on its fiscal
1998 consolidated financial statements.

(2)  BUSINESS COMBINATIONS

       On March 20, 1997 the company agreed to purchase, for approximately $535
million, O.I.L. Ltd. O.I.L. Ltd is a subsidiary of Ocean Group plc, of the
United Kingdom, and owns a fleet of approximately 100 vessels principally
composed of towing-supply and supply vessels operating in most major offshore
oil and gas exploration areas other than the United States. Final determination
of the purchase price is subject to certain conditions to be satisfied at
closing. The acquisition will be accounted for using the purchase method and
will be financed under a $600 million credit facility. The purchase agreement
calls for the closing to be no later than May 30, 1997, unless extended by both
parties.

       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. 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 condensed consolidated financial statements effective June 1,
1996. Unaudited pro forma results of operations assuming the acquisition had
taken place on April 1, 1995 would not be materially different than actual
results.

       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.
Operating results prior to the combination of the separate companies and the
combined amounts presented in the consolidated financial statements are
summarized below:

    Adjustments to conform Hornbeck's accounting policies to those of Tidewater
and to apply pooling-of-interests accounting reduced (increased) net earnings
of the combined entity for the above periods by $2,359,000 and ($536,000),
respectively. The adjustments to conform accounting policies relate to
Hornbeck's capitalizing and amortizing the cost of vessel drydockings and major
overhauls rather than expensing such costs as incurred.

    Prior to the combination Hornbeck's fiscal year end was December 31.
Tidewater's fiscal year end is March 31. In applying pooling-of-interests
accounting, the March 31, 1995 Tidewater statement of earnings was combined
with the Hornbeck statement of earnings for the year ended December 31, 1994.
Unaudited amounts for the nine-month period ended December 31, 1995 include
results of each entity for the nine-month period ended December 31, 1995.
Retained earnings of the combined entities were adjusted by $434,000 as of the
beginning of Tidewater's fiscal 1996 year to include the unaudited net earnings
of Hornbeck, including adjustments to conform accounting policies to those of
Tidewater, for the period January 1, 1995 to March 31, 1995. During this period
Hornbeck's revenues were $12,671,000. Additionally, the consolidated statement
of cash flows for the year ended March 31, 1996 was adjusted by $4,980,000 to
reflect the net increase in cash of Hornbeck for the three months ended March
31, 1995.

    Merger expenses of $9.6 million include legal, investment banking and
accounting fees related to the business combination. Also included in merger
expenses are payments under severance and employment agreements and a provision
for certain other related costs. Merger expenses are classified as other
expense in the Consolidated Statements of Earnings.

    In fiscal 1995 the company purchased for $35 million in cash the assets of
Brazos Gas Compressing Company, a subsidiary of Mitchell Energy & Development
Corporation, and the natural gas compression assets of Halliburton Company
using $55 million of available cash and borrowings of $150 million. The costs
of these acquisitions were allocated under the purchase method of accounting
based on the fair value of the assets acquired. In connection with the purchase
of the natural gas compression assets of Halliburton Company, goodwill of
approximately $25 million was recorded as other assets in the Consolidated
Balance Sheet and is being amortized in equal charges to earnings over a
15-year period.

    The results of Brazos' and Halliburton's operations have been consolidated
with the company's effective October 1, 1994, and December 1, 1994,
respectively. Unaudited pro forma combined results of operations of the company
and of Brazos and Halliburton, including appropriate purchase accounting

      The net changes in the valuation allowance for the years ended March 31,
1997 and 1996 were decreases of $3,164,000 and $2,108,000, respectively. These
changes were made due to the realization of certain international net operating
loss carryforwards. The remaining balance of the deferred tax assets are
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
$31,500,000 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 investments. As of
March 31, 1997, the undistributed earnings of these subsidiaries were
approximately $90,000,000.

(6)  LONG-TERM DEBT

      At March 31, 1997 the company had no long-term debt. Outstanding
long-term debt at March 31, 1996 of $2,934,000, all classified as current,
consisted of outstanding debt assumed in connection with the merger with
Hornbeck Offshore Services, Inc. on March 13, 1996.

      The company's revolving credit and term loan agreement (the "agreement")
consists of a $200 million revolving credit facility and a $400 million
acquisition term loan. The acquisition term loan is for financing the future
acquisition of O.I.L. Ltd. Borrowings will 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 of $200 million 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. Borrowings under the
acquisition term loan are payable in 28 quarterly installments beginning
September 30, 1997 and ending June 30, 2004. All of the borrowings under the
agreement are unsecured and the company pays an annual fee of .25% on the
unused portion of the revolving credit 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.

(7)  BENEFIT PLANS

      Upon meeting various citizenship, age and service requirements, employees
are eligible to participate in a defined contribution savings plan. The plan
held 510,772 shares and 522,216 shares of the company's common stock at March
31, 1997 and 1996, respectively. Amounts charged to expense for the plan for
1997, 1996 and 1995 were $1,694,000, $1,035,000, and $951,000, 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 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 1997, 1996 and 1995 include the following components:

      During the fourth quarter of fiscal 1996 the company recorded as other
expense a $3.0 million charge as a result of the removal of Marine fleet and
Compression field service personnel from the company's U.S. defined benefit
pension plan. Beginning April 1, 1996 these Marine and Compression 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.
Company contributions in cash to the plan are based on employee compensation,
as defined by the plan, and are subject to certain vesting requirements. The
costs of the plan for fiscal 1997 was $2,309,000.

      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.

      Net periodic postretirement health care and life insurance costs for
1997, 1996 and 1995 include the following components:

      The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation will be 9% in 1998, gradually declining to
5.5% 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 $2,235,000 at March 31, 1997 and change the
cost for the year ended March 31, 1997 by $329,000. The assumed discount rate
used in determining the accumulated postretirement benefit obligation was 7.5%
in 1997 and 1996.

(9) CAPITAL STOCK

      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, 1997, 2,271,040 shares of common stock are reserved for
issuance under the plans of which 332,528 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 ratable
installments over a three-year period from the grant date.

      The per share weighted-average fair values of stock options granted
during fiscal years 1997 and 1996 were $15.46 and $13.38, respectively, on the
dates of grant using the Black Scholes option-pricing model with the following
weighted-average assumptions:

      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 earnings per common share reflect only options
granted during fiscal years 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.

    Stock option activity during 1997, 1996 and 1995 was as follows:

      At March 31, 1997, 1996 and 1995, the number of options exercisable under
the stock option plans was 940,579, 771,125 and 531,403, respectively; and the
weighted average exercise price of those options was $21.51, $17.43 and $13.82,
respectively.

      The restricted stock plan permits the grant of company shares restricted
as to transferability and subject to a substantial risk of forfeiture. The
vesting restrictions and period during which the transferability restrictions
are applicable are determined on a case-by-case basis. 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.
At March 31, 1997, contingent awards totalling 25,409 restricted company shares
were outstanding, to be issued in conjunction with and as a result of the
exercise of certain stock options. All restrictions are removed from the
restricted shares six months after issuance.

      In accordance with an 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. These restricted shares vest at varying intervals
when the average sales price of the common stock reaches certain predetermined
levels. During the years ended March 31, 1997 and 1996, 25,000 shares in each
year vested due to the attainment of the first and second average sales price
levels applicable to those shares. The fair market value of the stock at the
time of the grant was classified in stockholders' equity as deferred
compensation-restricted stock and is being amortized by equal monthly charges
to earnings over approximately seven years, adjusted for vestings during the
seven year period.

      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 $84.8 million
on the purchase of 1,788,100 common shares at an average cost, including broker
commissions and fees, of $47.42 per share during 1997. All shares purchased
have been canceled.

      At March 31, 1997 and 1996, 3,000,000 shares of no par value preferred
stock were authorized and unissued.

      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





                                      F-17

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

(10) COMMITMENTS AND OTHER MATTERS

      An employment agreement exists with the company's chairman of the board,
president and chief executive officer whereby he will serve in such capacity
through December 31, 1997. 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 $ 7.8 million. The
amount that could be paid for certain benefits is not presently determinable.

      During the fourth quarter of fiscal 1997 and the third quarter of fiscal
1995, the company recorded as other expense charges of $2.8 million ($1.9
million after tax, or $.03 per common share) and $2.5 million ($1.6 million
after tax, or $.02 per common share), respectively, to establish reserves for
losses resulting from one of the company's insurers filing for liquidation and
for reserves to cover losses due to the potential insolvency of certain of the
company's insurers.

      During the fourth quarter of fiscal 1995, the company recorded as other
expense $5.9 million ($3.7 million after tax, or $.06 per common share) for the
cost of a restructuring program of its corporate headquarters and worldwide
marine operations which was designed to reduce costs and improve operating
efficiencies. Substantially all of the costs associated with the restructuring
program were paid before March 31, 1995. The restructuring resulted in the
elimination of approximately 150 positions, realignment of duties and
responsibilities and streamlining of administrative functions. The charge
reflects the costs associated with staff reductions, relocations and related
transition expenses.

      The Internal Revenue Service has 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. 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.
While the amount, if any, of such claims for which the company ultimately may
be held liable is not presently determinable, if the claimants and all
similarly situated employees and former employees who might file claims were
successful, the aggregate amount of the company's liability, based on available
information, could approximate $15 million. The company is in the process of
defending against these claims and assessments and, in management's opinion,
the ultimate outcome of these matters will not have a material adverse effect
on the company's financial position or the results of its ongoing operations.

      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.

as of March 19, 1997 (the "Effective Date"), by and among Tidewater Inc., a

"Administrative Agent"), First National Bank of Commerce, a national banking
association, as documentation agent (the "Documentation Agent") and Texas

Agent")(the Administrative Agent, the Documentation Agent and the Syndication

hereof (the "Lenders").


                                    RECITALS

         A.      Subject to the terms and conditions of this Agreement, the
Lenders have severally agreed (i) to make a $200,000,000 revolving line of
credit available to the Companies, and (ii) to make a $400,000,000 term loan to
the Companies, and the Companies have agreed to accept the line of credit and
borrow the term loan from the Lenders.


         B.      The Companies, Agents and Lenders desire to set forth the
terms and conditions of the loans herein.


                                   AGREEMENT

         NOW, THEREFORE, for and in consideration of the mutual covenants,
agreements and undertakings herein contained, the Agents, Lenders and the
Companies hereby agree as follows:


         Section 1.  Commitment of Lenders.  Subject to the terms and
conditions hereof, each Lender severally agrees to make a line of credit and
loan to the Companies, on the terms and conditions set forth in this Agreement,
in the aggregate principal amounts set forth on Exhibit B hereto:


         1.1     Line of Credit; Conversion Term Loan.  The Lenders shall
severally establish a revolving line of credit (the "Line of Credit") which may
be drawn upon by the Companies on
<PAGE>   7
any Business Day during the period from the date hereof until and including the
Drawdown Termination Date, in such amounts (but not less than $5,000,000 per
Advance and above $5,000,000 in even multiples of $1,000,000) as the Companies
may from time to time request (individually, an "Advance" and, collectively,
the "Advances"), but not exceeding the Commitments for the Line of Credit set
forth on Exhibit B hereto (the "Line of Credit Commitments").  The amount
outstanding under said Line of Credit as of the close of business on the
Drawdown Termination Date shall then convert on the following day to a four (4)
year term loan (the "Conversion Term Loan") with principal payable quarterly on
a four (4) year amortization schedule.  The credit available to the Companies
from time to time under the Line of Credit shall be reduced by the aggregate of
the face amount of any and all unpaid Advances made by the Lenders to the
Companies pursuant to this Agreement and shall constitute the "Available
Credit."

         1.2     Acquisition Term Loan.  The Lenders shall severally make a
term loan (the "Acquisition Term Loan") to the Companies on the date the
Acquisition Date, in the amounts set forth on Exhibit B hereto (the
"Acquisition Term Loan Commitments").  If the Acquisition does not occur on or
prior to May 30, 1997, unless the parties hereto have extended such date on
terms and conditions satisfactory to the parties hereto, the Acquisition Term
Loan Commitments shall terminate and be of no further force and effect.  The
termination of the Acquisition Term Loan Commitments shall not affect the
availability of the Line of Credit and Conversion Term Loan pursuant to this
Agreement.

         1.3     Borrowing Procedure Under the Credit Facility.  Advances shall
be made as follows:  (i) in the case of a Base Rate Advance, on notice from the
Company to the Administrative Agent received by the Administrative Agent no
later than 10:00 A.M. (Eastern time) on the date of such proposed Advance,
specifying the amount thereof; and (ii) in the case of a Eurodollar Rate
Advance, on notice from the Company to the Administrative Agent at least three
(3) Business Days prior to the date of such proposed Advance.  The
Administrative Agent will use its best efforts to give telephone notice of a
proposed Advance on the same day such notice is received by the Administrative
Agent from the Company.  Not later than 2:00 P.M. (Eastern time) on the date of
such Advance and upon fulfillment of the applicable conditions set forth in
Sections 7A and 7B (in the case of Advances under the Line of Credit and under
the Acquisition Loan for the Acquisition) and Section 8 (in the case of each
other Advance under the Line of Credit), the Lenders will make such Advance
available to the Administrative Agent, which shall make such total Advance
available to the Company in same day funds at the Administrative Agent's office
at 100 Federal Street, Boston, Massachusetts.  The request for an Advance under
the Line of Credit for any purpose other than the Acquisition shall constitute
a certification by the Companies that all of the representations and warranties
contained in Section 5 are true and correct as of the date of such request.
Subject to the provisions of Section 9.2 hereof, the Lenders shall be obligated
to fund Advances in proportion to their respective Commitments.  The
obligations of the Lenders under this Agreement shall be separate and





                                    -  2  -
<PAGE>   8
several and not joint and several or solidary; none of the Lenders shall be
responsible or liable for the acts or omissions of any of the other Lenders.

         1.4  Use of Proceeds.  The Companies shall use the proceeds of the
Line of Credit only (i) for the refinancing of any existing indebtedness of the
Companies pursuant to the Amended and Restated Loan Agreement among the
Companies, the Agents and certain other lenders, dated as of December 29, 1995,
as amended, and (ii) for general corporate purposes not inconsistent with the
provisions of this Agreement.  The Companies shall use the proceeds of the
Acquisition Term Loan only for financing, in part, the acquisition of all of
the outstanding capital stock of O.I.L. Ltd. and its subsidiaries listed on
Schedule 1.4 hereto (the "Acquisition") and to pay certain fees and expenses in
connection therewith; the Companies may also use the proceeds of the Line of
Credit for the same purposes as the Acquisition Term Loan.

         1.5  Liability of the Companies; Additional Domestic Subsidiaries.
Irrespective of the Company or Companies who directly or indirectly receive the
amounts funded on Advances, each of the Companies shall be liable jointly and
severally and solidarily to the Lenders for all amounts outstanding from time
to time under the Credit Facility.  The Company shall promptly notify the
Documentation Agent of the creation or acquisition of any company that becomes
a Domestic Subsidiary after the Effective Date and shall sign such instruments
as the Documentation Agent prepares to make such new Domestic Subsidiary a

termination of said agreement and the credit facility available thereunder.

         Section 2.  Promissory Notes.

         2.1     Line of Credit Notes.  The Line of Credit shall be evidenced
by promissory notes of the Companies, each in the form of Exhibit "C" hereto,
dated the Effective Date, and payable to each Lender respectively (together
with any and all renewals, extensions, rearrangements and/or modifications
thereof, the "Line of Credit Notes"), in the amount of the Lenders' respective
Line of Credit Commitments, with appropriate insertions, and payable in full on
the Drawdown Termination Date.

         2.2     Conversion Term Notes.  The Conversion Term Loan shall be
evidenced by promissory notes of the Companies in the form of Exhibit "D"

                                    -  3  -
<PAGE>   9
quarterly installments of principal in an amount equal to one-sixteenth
(1/16th) of the initial principal balance thereof, and shall be payable in full
on the fourth anniversary of the Drawdown Termination Date.  Once the
Conversion Term Loan is initially funded, the Lenders shall not fund any
additional Advances under the Conversion Term Loan.

         2.3     Acquisition Term Notes.  The Acquisition Term Loan shall be
evidenced by promissory notes of the Companies in the form of Exhibit "E"

         2.4     Principal Payment Dates.  Principal payments under each
respective Loan shall be allocated first to Base Rate Tranches, then to
Eurodollar Rate Tranches having a Eurodollar Rate Interest Period ending on the
quarterly installment payment date, and then to Eurodollar Rate Tranches having
a Eurodollar Rate Interest Period ending subsequent to the quarterly
installment payment date (in which case the Companies shall pay any loss or
expense incurred or sustained by the Lenders as specified in Section 3.4(e)
hereof).


         Section 3.  Interest and Fees.

         3.1     Interest.  The unpaid principal of the Credit Facility shall
bear interest at one (or both) of the following interest rates, at the
Company's option:  (i) Base Rate plus the Applicable Base Rate Margin or (ii)
Eurodollar Rate plus the Applicable Eurodollar Rate Margin; provided, that the
interest rate on the Acquisition Term Loan and any Advance under the Line of
Credit for the Acquisition shall be at the Federal Funds Rate plus 1.0% for the
period from the Acquisition Date through the fourth (4th) day thereafter.  The
Company shall select the interest rate applicable to each Tranche at the time
of funding each Advance, and the selected interest rate shall continue as to
said Tranche until changed in accordance with the following.  The Company shall
notify the Administrative Agent of the Company's desire to change the interest
rate on Advances (or any portion thereof) not less than three (3) Business Days
prior to the date on which such change shall be effective.  The Company may
change from Base Rate Advances to Eurodollar Rate Advances at any time without
payment of premium or penalty, but the Company may change from Eurodollar Rate
Advances to Base Rate Advances only as of the last day of a Eurodollar Rate
Interest Period without payment of premium or penalty.  In the absence of any
specific rate election by the Company, the Credit Facility shall bear interest
at the Base Rate.  Not more than twelve (12) Line of Credit Eurodollar Rate
Tranches shall be permitted at any time, and not more than two (2) Conversion
Term Loan or Acquisition Term Loan Eurodollar Rate Tranches shall be permitted
at any time.  No Credit Facility Tranche may have





                                    -  4  -
<PAGE>   10
a principal amount of less than $5,000,000, and each Tranche shall be
proportionately the same on each Note.

         3.2     Administrative Agent's Determination.  (a) The Administrative
Agent shall determine the amount of interest payable on each Tranche, and its
determination shall be conclusive in the absence of manifest error.  The
Administrative Agent shall endeavor to notify the Company of the amount of any
interest payment prior to the date on which an interest payment is due:
provided that the failure of the Administrative Agent to provide such notice
shall not affect the Companies' obligation to pay interest on such date.

         (b)     If the Administrative Agent gives notice to the Company that
no Eurodollar Rate is quoted to the Administrative Agent for the applicable
Eurodollar Rate Interest Period or in the applicable amounts, then (i) the
obligation of the Lenders to make a Eurodollar Rate Advance and the ability of
the Company to select the Eurodollar Rate for a Tranche shall be suspended, and
(ii) the Companies shall either prepay all Eurodollar Rate Tranches for which
an interest rate is to be determined on such date or the Notes shall thereafter
bear interest at the Base Rate plus the Applicable Base Rate Margin.

         (c)     If any applicable domestic or foreign law, treaty, rule or
regulation (whether now in effect or hereinafter enacted or promulgated,
including Regulation D of the Board of Governors of the Federal Reserve System)
or any interpretation or administration thereof by any governmental authority
charged with the interpretation or administration thereof (whether or not
having the force of law):

                 (i)  changes the basis of taxation of payments to the Lenders
         of any principal, interest, or other amounts attributable to any
         Eurodollar Rate Tranche (other than taxes imposed on the overall net
         income of the Lenders or any lending office of the Lenders by any
         jurisdiction in which the Lenders or any such lending office is
         located);

                 (ii)  changes, imposes, modifies, applies or deems applicable
         any reserve, special deposit, insurance assessments or similar
         requirements in respect of any such Eurodollar Rate Tranche (excluding
         those for which the Lenders are fully compensated pursuant to
         adjustments made in the definition of Eurodollar Rate) or against
         assets of, deposits with or for the account of, or credit extended by,
         the Lenders; or

                 (iii)  imposes on the Lenders or the interbank eurocurrency
         deposit and transfer market any other condition affecting any such
         Eurodollar Rate Tranche,

and the result of any of the foregoing is to increase the cost to the Lenders
of funding or maintaining any such Eurodollar Rate Tranche (other than costs
for which the Lenders are fully





                                    -  5  -
<PAGE>   11
compensated pursuant to adjustments made in the definition of Eurodollar Rate)
or to reduce the amount of any sum receivable by the Lenders in respect of any
such Eurodollar Rate Tranche by an amount deemed by the Lenders to be material,
then the Administrative Agent shall promptly notify the Companies in writing
(such writing including the necessary calculations in reasonable detail) of the
happening of such event and the Companies shall upon demand pay to the Lenders
such additional amount or amounts as will compensate the Lenders for such
additional cost or reduction accrued as of the time of such notice and
thereafter, the Companies may either continue to pay to the Lenders such
additional amount as will compensate the Lenders for the additional cost or
reduction of Eurodollar Rate Tranches, or the Companies may elect, by giving to
the Administrative Agent not less than three Business Days' notice, to change
the interest rate applicable to such Tranche from the Eurodollar Rate plus the
Applicable Eurodollar Rate Margin to the Base Rate plus the Applicable Base
Rate Margin.

         (d)     Notwithstanding any other provision hereof, if any change in
applicable laws, treaties, rules or regulations or in the interpretation or
administration thereof of or in any jurisdiction whatsoever, domestic or
foreign, shall make it unlawful or impracticable for the Lenders to maintain
Eurodollar Rate Tranches bearing interest at the Eurodollar Rate plus the
Applicable Eurodollar Rate Margin, or shall materially restrict the authority
of the Lenders to purchase, sell or take certificates of deposit or offshore
deposits of dollars, then all Eurodollar Rate Tranches which are then
outstanding and which cannot lawfully or practicably be maintained shall
immediately cease to bear interest at the Eurodollar Rate plus the Applicable
Eurodollar Rate Margin and shall commence to bear interest at the Base Rate
plus the Applicable Base Rate Margin.  The Companies agree to indemnify the
Lenders and hold them harmless against all costs, expenses, claims, penalties,
liabilities and damages which may result from any such change in law, treaty,
rule, regulation, interpretation or administration, arising out of or in
connection with this Agreement and the Loans.

         (e)     The Companies will indemnify the Lenders against, and
reimburse each Lender on demand for, any loss or expense incurred or sustained
by the Lenders (including without limitation, any loss or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired
by the Lenders to fund or maintain Eurodollar Rate Tranches) as a result of (i)
any payment or prepayment (whether authorized or required hereunder or
otherwise) of all or a portion of any such Tranche on a day other than the day
on which the applicable Eurodollar Rate Interest Period ends, (ii) any payment
or prepayment, whether required hereunder or otherwise, of Eurodollar Rate
Tranches made after the delivery, but before the effective date, of an election
to have the Eurodollar Rate plus the Applicable Eurodollar Rate Margin apply to
a Eurodollar Rate Tranche, if such payment or prepayment prevents such election
from becoming fully effective, (iii) the failure of any Eurodollar Rate Tranche
to be made by the Lenders or of any such election to become effective due to
any condition precedent to a Eurodollar Rate Tranche not being satisfied or due
to any other action or inaction of the Companies, (iv) the Companies' election
to change the interest rate from the Eurodollar Rate plus the Applicable
Eurodollar Rate Margin to the Base Rate plus the Applicable Base Rate





                                    -  6  -

Margin pursuant to Section 3.2(f)(iv) hereof, or (v) the occurrence of a
Default or the non-payment of the Notes at maturity of the Notes for any reason
as set forth in Section 3.3 hereof.  For purposes of this Subsection, funding
losses arising by reason of liquidation or reemployment of deposits or other
funds acquired by the Lenders to fund or maintain Eurodollar Rate Tranches
shall be calculated as (A) the remainder, if a positive number, obtained by
subtracting (1) the yield (reflecting both stated interest rate and discount,
if any) to maturity of obligations of the United States Treasury as determined
by the Administrative Agent in an amount equal or comparable to such advance
for the period of time commencing on the date of the payment, prepayment or
change of rate as provided above and ending on the last day of the subject
Eurodollar Rate Interest Period, from (2) the Eurodollar Rate plus the
Applicable Eurodollar Rate Margin of the subject Eurodollar Rate Interest
Period, (B) times the number of days from the date of payment, prepayment or
change of rate to the last day of the Eurodollar Rate Interest Period, divided
by 360, (C) times the amount of the applicable Eurodollar Rate Tranche.  Any
payment due under this section will be paid to the Administrative Agent within
five days after the Administrative Agent delivers to the Company a certificate
setting forth in reasonable detail the amount of such payment, which
certificate shall be conclusive in the absence of manifest error.

         (f)     The Companies covenant and agree that:

                 (i)  The Companies will pay, when due and on an after-tax
         basis, all present and future stamp and other taxes, levies, costs and
         charges whatsoever imposed, assessed, levied or collected on or in
         respect of any Eurodollar Rate Tranche (other than taxes, levies,
         costs or charges imposed on or measured by the overall net income of
         the Lenders, or any lending office of the Lenders by any jurisdiction
         in which the Lenders or any such lending office is located) (all such
         non-excluded taxes, levies, costs and charges being collectively
         called "Reimbursable Taxes").  Promptly after the date on which
         payment of any Reimbursable Taxes is due pursuant to applicable law,
         the Companies will, at the request of the Administrative Agent,
         furnish to the Lenders evidence in form and substance satisfactory to
         the Lenders that the Companies have met their obligation under this
         subsection.

                 (ii)  The Companies will indemnify the Administrative Agent
         and the Lenders against, and reimburse the Administrative Agent and
         the Lenders on demand for, any Reimbursable Taxes paid by the
         Administrative Agent and the Lenders and any loss, liability, claim or
         expense, including interest, penalties and legal fees, that the
         Administrative Agent and the Lenders may incur at any time arising out
         of or in connection with the failure of the Companies to make any
         payment of Reimbursable Taxes when due.  Any payment due under this
         subsection will be paid to the Administrative Agent within five days
         after demand therefor by the Administrative Agent.

<PAGE>   13
                 (iii)  All payments on account of the principal of, and
         interest on, Eurodollar Rate Tranches and all other amounts payable by
         the Companies to the Lenders hereunder shall be made free and clear of
         and without reduction by reason of any Reimbursable Taxes.

                 (iv)  If the Companies are ever required to pay any
         Reimbursable Taxes with respect to any Eurodollar Rate Tranches, the
         Companies may elect, by giving to the Administrative Agent not less
         than three (3) Business Days' notice, to change the interest rate
         applicable to any such advance from the Eurodollar Rate plus the
         Applicable Eurodollar Rate Margin to the Base Rate plus the Applicable
         Base Rate Margin, but such election shall not diminish the Companies'
         obligation to pay all Reimbursable Taxes theretofore imposed,
         assessed, levied or collected.

         (g)     If any applicable law or regulation, or the action of any
applicable regulatory requirement increases the reserves or  capital required
for the Credit, the Administrative Agent shall promptly deliver a certificate
to the Company specifying in reasonable detail the additional amount as will
compensate the Lenders for the additional costs, which certificate shall be
conclusive in the absence of manifest error.  The Companies shall pay the
amount specified in such certificate promptly upon receipt.

         3.3     Interest Payment Dates; Late Payment and Default Rate.
Interest on Base Rate Advances under any of the Loans shall be payable
quarterly in arrears on the last day of each March, June, September and
December, beginning March 31, 1997; interest on Eurodollar Rate Advances shall
be payable on the last day of each Eurodollar Rate Interest Period (1 month, 2
months, 3 months or 6 months), and in the case of 6-month Eurodollar Rate
Interest Periods, also at the end of the first 3 months thereof.  Upon the
occurrence of a Default and for so long as such Default remains uncured, the
interest rate on the Notes shall be increased to the Base Rate plus the
Applicable Base Rate Margin plus two percent (2%).  Interest after maturity of
the Notes for any reason whatsoever (including acceleration following the
occurrence of an Event of Default) shall be increased to the Base Rate plus the
Applicable Base Rate Margin plus two percent (2%) and shall be payable on
demand.

         3.4     Facility Fee; Agents' Fee.

         (a)     A facility fee equal to the Applicable Facility Fee Rate on
the daily average Available Credit shall begin to accrue on the fourth (4th)
Business Day following the Effective Date and shall be payable by the Companies
quarterly in arrears on the last day of each March, June, September and
December, beginning March 31, 1997, through and including the Drawdown
Termination Date.





                                    -  8  -
<PAGE>   14
         (b)     An Agents' fee for the Credit Facility in the amount set forth
in the Agents' Fee Agreement shall be payable by the Companies to the Agents in
accordance with the Agents' Fee Agreement.

         3.5     Method of Calculating Interest and Fees.  Interest at the Base
Rate (based on the Prime Rate) shall be computed on the basis of a year
consisting of 365 days (366 days in a leap year) and paid for the actual days
elapsed.  Interest at the Base Rate (based on the Federal Funds Rate) shall be
computed on the basis of a year consisting of 360 days and a month consisting
of 30 days and paid for the actual days elapsed.  Interest at the Eurodollar
Rate shall be computed on the basis of a year consisting of 360 days and a
month consisting of 30 days and paid for the actual days elapsed.  Interest at
the Applicable Facility Fee Rate shall be computed on the basis of a year
consisting of 360 days and a month consisting of 30 days and paid for the
actual days elapsed.


         Section 4.  Payments, Reduction or Termination of the Credit and 
Prepayments.

         4.1     Place of Payment.  All payments hereunder (including payments
of interest, principal and fees) with respect to the Notes shall be made by the
Companies to the Administrative Agent in immediately available funds, prior to
1:00 p.m. (Eastern time) at its offices at 100 Federal Street, Boston,
Massachusetts, or at such other place as may be designated by Administrative
Agent to the Companies in writing.  Any payment received after 1:00 p.m.
(Eastern time) shall be deemed received on the next Business Day.  Whenever any
payment to be made hereunder or under the Notes fall on a date other than a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall be included in the computation of payment of
interest or any fees.

         4.2     Reduction of Credit under the Line of Credit; Prepayments.
(a) The Companies may from time to time (in the case of Base Rate Tranches) or
at the end of any Eurodollar Rate Interest Period (in the case of Eurodollar
Rate Tranches), upon at least three (3) Business Days's prior telephonic notice
(confirmed in writing) to Administrative Agent, permanently reduce the amount
of the Commitments available under the Line of Credit (which Commitments shall
be reduced proportionately by the Lenders), but only upon payment of the
outstanding principal amount of the Line of Credit Notes in excess of the then
reduced amount of the Commitments available under the Line of Credit.  Any such
reduction shall be in an amount of $10,000,000.00 or an integral multiple
thereof.  The Companies may at any time (in the case of Base Rate Tranches) or
at the end of any Eurodollar Rate Interest Period (in the case of Eurodollar
Rate Tranches), on like notice, terminate the Commitments available under the
Line of Credit upon payment in full of the Line of Credit Notes and other
liabilities of the Companies hereunder.  In the case of either a reduction or
termination of the Commitments, the Companies shall thereafter have no right to
increase or restore the Commitments.





                                    -  9  -
<PAGE>   15
         (b)     The Companies may from time to time (in the case of Base Rate
Tranches) or at the end of any Eurodollar Rate Interest Period (in the case of
Eurodollar Rate Tranches) prepay the principal of the  Line of Credit Notes in
whole or in part without premium; provided, however, any partial prepayment of
principal shall be in an amount of $1,000,000.00 or any integral multiple
thereof.  Any prepayment of the principal of the Line of Credit Note shall
include accrued interest to the date of prepayment on the principal amount
being prepaid.

         4.3     Prepayments of Term Notes.   The Companies may from time to
time (in the case of Base Rate Tranches) or at the end of any Eurodollar Rate
Interest Period (in the case of Eurodollar Rate Tranches), upon at least three
Business Day's prior telephonic notice (confirmed in writing) to the
Administrative Agent, prepay the principal of the Term Notes in whole or in
part without premium; provided, however, any partial prepayment of principal
shall be in an amount not less than $20,000,000.00.  Any prepayment of the
principal of the Term Notes shall include accrued interest to the date of
prepayment on the principal amount being prepaid.  All prepayments when made
shall be applied pro rata to unpaid installments of principal, and shall not
relieve the Companies from the obligation to pay scheduled installments of
principal (as reduced by the pro rata application of the prepayment) in
accordance with the Term Notes.

         4.4     Pro Rata Payments.  All payments and prepayments of principal,
interest, fees (except the fees payable to the Agents pursuant to the Agents'
Fee Agreement), and other amounts paid by the Companies to the Administrative
Agent from time to time under this Agreement shall be promptly wired by the
Administrative Agent to the Lenders in proportion to their respective
Commitments.

         Section 5.  Representations and Warranties of the Companies.

         The Companies represent and warrant to the Lenders that as of the
Effective Date and any date thereafter:

         5.1     Corporate Existence.  Each of the Companies is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction in which it is incorporated and is duly qualified and in good
standing in all jurisdictions wherein the property it owns or the business it
transacts make such qualification necessary as a foreign corporation, except
where the failure to so qualify would not materially impair the ability of the
Company or any of its Subsidiaries to operate its business or own its assets;
and each of the Companies has and will continue to have (i) all necessary
corporate power and authority and (ii) all necessary material permits,
licenses, patents, trademarks and other intangibles, to acquire, own and hold
the property and all other properties it purports to own and hold and to carry
on  its business as now conducted.  The Domestic Subsidiaries listed on Exhibit
"A" attached hereto constitute all of the Domestic Subsidiaries of the Company.





                                    -  10  -
<PAGE>   16
         5.2     Authorization; Validity.  Each of the Companies is and/or has
been duly authorized to execute and deliver this Agreement and the Notes, and
is and will continue to be duly authorized to borrow monies hereunder and to
perform its obligations under this Agreement and the Notes.  This Agreement and
the Notes, as executed and when delivered, shall constitute the legal, valid
and binding obligations of each of the Companies, enforceable in accordance
with their respective terms.

         5.3     Conflicting Agreements and Other Matters.  Neither the Company
nor any of its Subsidiaries is a party to any contract or agreement or subject
to any charter or other corporate restriction which materially and adversely
affects the business, property, assets, or financial condition of the Company
and its Subsidiaries, taken as a whole.  Neither the execution nor delivery of
this Agreement or the Notes, nor fulfillment of nor compliance with the terms
and provisions hereof and of the Notes will conflict with, or result in a
breach of the terms, conditions or provisions of, or constitute a default
under, the charter or by-laws of the Company or any of its Subsidiaries, any
award of any arbitrator or any agreement (including any agreement with
stockholders) or instrument to which the Company or any of its Subsidiaries is
now a party, or result in the creation of any Lien on any property or assets of
the Company or any of its Subsidiaries, or constitute a violation of any law,
statute, rule, regulation, order, judgment or decree to which the Company or
any of its Subsidiaries is subject.  Neither the Company nor any of its
Subsidiaries is a party to, or otherwise subject to any provision contained in,
any instrument evidencing indebtedness of the Company or such Subsidiary, any
agreement relating thereto or any other contract or agreement (including its
charter) which (i) limits the amount of, or otherwise imposes restrictions on
the incurring of, Debt of the Companies of the type to be evidenced by the
Credit, or (ii) which imposes restrictions on the granting of Liens by the
Companies on otherwise unencumbered assets of the Companies as security for the
Credit.

         5.4     Financial Statements.  The Company has furnished the Lenders
with the consolidated balance sheets of the Company and its Subsidiaries as at
fiscal year end in each of the years 1994 through 1996, inclusive, and for the
nine-month period ending December 31, 1996, and a consolidated statement of
income and statement of cash flows for each such fiscal year and such
nine-month period, all identified by a principal financial officer of such
Company and all (other than any financial information for such nine-month
period) certified by KPMG Peat Marwick LLP (or its predecessor).  Such
financial statements (including any related schedules and/or notes) are true
and correct in all material respects (subject, as to interim statements, to
changes resulting from audits and normal year-end adjustments) and have been
prepared in accordance with generally accepted accounting principles, and,
unless otherwise set forth therein, consistently followed throughout the
periods involved and show all liabilities, direct and contingent, of the
Company and its Subsidiaries required to be shown in accordance with such
principles.  The balance sheets fairly present the condition of the Company and
its Subsidiaries as at the dates thereof, and the related statements of
earnings, stockholders' equity and cash flows fairly present the results of the
operations of the Company and its Subsidiaries





                                    -  11  -
<PAGE>   17
for the periods indicated.  As of the date of this Agreement, there has been no
material adverse change in the business, condition or operations (financial or
otherwise) of the Company and its Subsidiaries taken as a whole, since December
31, 1996.

         5.5     Litigation and Contingent Liabilities.  No litigation or
governmental proceedings are pending or threatened against the Company or any
of its Subsidiaries, the results of which are likely to materially adversely
affect the financial condition or operations of the Company and its
Subsidiaries on a consolidated basis, except as provided for or disclosed in
the financial statements referred to in Section 5.4 hereof.  Other than any
liability incident to such litigation or proceedings provided for or disclosed
in the financial statements referred to in Section 5.4 hereof, or any other
material contingent liabilities provided for or disclosed in the financial
statements referred to in Section 5.4 hereof, the Company and its Subsidiaries,
on a consolidated basis, do not have any material contingent liabilities.

         5.6     Outstanding Debt.  Neither the Company nor any of its
Subsidiaries has outstanding any Debt except as permitted by Section 6.9 and as
set forth on Schedule 5.6 attached hereto and made a part hereof.  There exists
no default under the provisions of any instrument evidencing Debt or of any
agreement relating thereto.

         5.7     Title to Properties.  Except for assets which are the subject
of capitalized lease obligations, the Company and its Subsidiaries each have
and will continue to have good and marketable title to their respective
properties and assets, including the properties and assets reflected in the
financial statements described in Section 5.4 hereof, subject to no Lien of any
kind except Liens permitted by Section 6.8 hereof.  All leases necessary in any
material respect for the conduct of the respective businesses of the Company
and its Subsidiaries are valid and subsisting and are in full force and effect.

         5.8     Purpose.  The proceeds of the Loan will be used by the
Companies only for the purposes specified in Section 1.4 hereof.

         5.9     Margin Stock.  Neither the Company nor any of its Subsidiaries
is engaged in the business of purchasing or selling margin stock (as defined in
any regulation of the Board of Governors of the Federal Reserve System) or
extending credit to others for the purpose of purchasing or carrying margin
stock and no part of the proceeds of any borrowing hereunder will be used to
purchase or carry any margin stock or for any other purpose which would violate
any of the margin regulations of such Board of Governors.

302 of ERISA and Section 412 of the Code), whether or not waived, exists with
respect to any Plan (other than a Multiemployer Plan).  No liability to the

Plan (other than a Multiemployer Plan) by the Company or any of its
Subsidiaries which is or would be materially adverse to the Company and its
Subsidiaries

or presently expects to incur any withdrawal of liability under Title IV of
ERISA with respect to any Multiemployer Plan which is or would be materially
adverse to the Company and its Subsidiaries taken as a whole.  The execution
and delivery of this Agreement will not, and the delivery of the Notes will
not, involve any transaction which is subject to the prohibitions of Section
406 of ERISA or in connection with which a tax could be imposed pursuant to
Section 4975 of the Code.  The term "Code" shall mean the Internal Revenue Code
of 1986, as amended; the term "Plan" shall mean an "employee pension benefit
plan" (as defined in Section 3 of ERISA) which is or has been established or
maintained, or to which contributions are or have been made, by the Company or
by any trade or business, whether or not incorporated, which, together with the
Company, is under common control, as described in Section 414(b) or (c) of the
Code; and the term "Multiemployer Plan" shall mean any plan which is a
"multiemployer plan" (as such term is defined in Section 4001(a)(3) of ERISA).

         5.11  Consents.  No consent, approval or authorization of, or
registration or declaration with, any federal or state governmental authority
or other regulatory agent for the validity of the execution and delivery or for
the performance by any of the Companies of this Agreement and the Notes or any
agreement or instrument executed in connection herewith, is or will be
required.

         5.12  Tax Returns; Taxes.  The Company has and each of its
Subsidiaries have filed all federal, state, foreign and other income tax
returns which, to the knowledge of the officers of the Company, are required to
be filed by any jurisdiction, and each has paid and will pay all taxes which
have or subsequently become due pursuant to said returns or pursuant to any
assessments, except those contested in good faith by appropriate proceedings
and for which sufficient reserves have been or will be established.

         5.13  Compliance with Laws.  The Company and each of its Subsidiaries
is in substantial compliance with all laws and regulations applicable to the
Companies and the businesses conducted by them (including without limitation,
laws and regulations relating to pollution and environmental control, equal
employment opportunity and employer safety) in all jurisdictions in which the
Company and each of its Subsidiaries is presently doing business, and the
Company will substantially comply and cause each of its Subsidiaries to
substantially comply with all such laws and regulations which may be legally
imposed in the future in jurisdictions in which the Company or any Subsidiary
may then be doing business.

         5.14  Foreign Assets Control Regulations.  Neither the borrowing by

         5.15  Disclosure.  Neither this Agreement nor any other document,
certificate or statement furnished to the Lenders by or on behalf of the
Company and the Subsidiaries in connection herewith contains any untrue
statement of a material fact or omits to state a material fact necessary in
order to make the statements contained herein and therein not misleading.
There is no fact peculiar to the Company or any of its Subsidiaries which

financial condition, of the Company and any of its Subsidiaries, taken as a
whole, and which has not been set forth in this Agreement or in the other

at, on, in or under the Properties or, to the best knowledge of the Companies,
at or from any adjacent site or facility, except for Hazardous Materials used,
produced, manufactured, processed, generated, stored, disposed of, released and
managed in the ordinary course of business in compliance with all applicable
Environmental Requirements, except where failure to comply could not reasonably
be expected to have a material adverse affect on the business, operations, or
financial condition of the Company and its Subsidiaries, taken as a whole.

         (iv)  Except as set forth in Schedule 516, the Company and each of its
Subsidiaries has procured all permits, licenses or authorizations (or any
variances or waivers) necessary under Environmental Requirements for the
conduct of its business.

                 and Exchange Commission shall be deemed to satisfy the
                 requirements of this clause (b);

         (c)     promptly upon transmission thereof, copies of all such
                 financial statements, proxy statements, notices and reports as
                 the Company shall send to its public stockholders and copies
                 of all registration statements (without exhibits) and all
                 reports which the Company files with the Securities and
                 Exchange Commission (or any governmental body or agency
                 succeeding to the functions of the Securities and Exchange
                 Commission);

         (d)     promptly upon receipt thereof, a copy of each other report
                 submitted to the Company or any of its Subsidiaries by
                 independent accountants in connection with any annual, interim
                 or special audit made by them of the books of the Company or
                 any of its Subsidiaries and which the Company or any of its
                 Subsidiaries shares with the audit committee of the Board of
                 Directors of the Company;

         (e)     with reasonable promptness, such other financial data as
                 Lenders may reasonably request;

         (f)     as soon as practicable and in any event within ninety (90)
                 days after the end of each fiscal year, a copy of the
                 Company's internal statement of operations by area; and

                 the ensuing fiscal year, setting forth the anticipated
                 revenues and expenses for such year, the incurrence and
                 repayment of Debt during such year, and such other matters as
                 the Lenders may reasonably require.

Together with each delivery of financial statements required by clauses (a) and
(b) above, the Company will deliver to the Documentation Agent an original of
an Officer's Certificate demonstrating (with computations in reasonable detail)
compliance with Sections 6.12, 6.13 and 6.14, stating that there exists no
Event of Default or Default, or, if any such Event of Default or Default
exists, specifying the nature thereof, the period of existence thereof and what
action the Company proposes to take with respect thereto.  Together with each
delivery of financial statements required by clause (b) above, the Company will
also deliver to the Documentation Agent an original of a certificate of said
accountants stating that, in making the audit necessary to the certification of
such financial statements, they have obtained no knowledge of any Default or
any Event of Default, or, if any such Event of Default or Default exists,
specifying the nature





                                    -  16  -
<PAGE>   22
and period of existence thereof.  Such accountants, however, shall not be
liable to anyone by reason of their failure to obtain knowledge of any such
Event of Default or Default which would not be disclosed in the course of an
audit conducted in accordance with generally accepted auditing standards.

         The Companies also agree that forthwith upon the chief executive
officer, principal financial officer or principal accounting officer of the
Company obtaining knowledge of:

              (i)         an Event of Default or Default;

             (ii)         a material adverse change in the financial condition,
                          business or operations of the Company and its
                          Subsidiaries, taken as a whole;

            (iii)         the institution of legal proceedings against the
                          Company and/or any Subsidiary, which is likely to
                          materially adversely affect the financial condition,
                          business or operations of the Company and its
                          Subsidiaries, taken as a whole, or which in any
                          manner draws into question the validity of or is
                          likely to impair the ability of the Companies to
                          perform their obligations under this Agreement or the
                          Notes;

             (iv)         the occurrence of any default (after the passage of
                          any grace period) by a Company under any agreement or
                          note evidencing borrowed money for an aggregate
                          initial principal amount equal to or greater than
                          $1,000,000;

              (v)         any (A) Environmental Liability which is likely to
                          materially adversely affect the financial condition,
                          business or operations of the Company and its
                          Subsidiaries, taken as a whole, (B) pending,
                          threatened or anticipated Environmental Proceedings,
                          which is likely to materially adversely affect the
                          financial condition, business or operations of the
                          Company and its Subsidiaries, taken as a whole, (C)
                          Environmental Notice which is likely to materially
                          adversely affect the financial condition, business or
                          operations of the Company and its Subsidiaries, taken
                          as a whole, (D) Environmental Judgment or Order which
                          is likely to materially adversely affect the
                          financial condition, business or operations of the
                          Company and its Subsidiaries, taken as a whole, or
                          (E) Environmental Releases at, on, in, under or in
                          any way materially affecting the Properties;

             (vi)         any violation of the provisions of Section 6.17
                          hereto relating to ERISA compliance; or

            (vii)         the occurrence of any other event that is likely to
                          impair the ability of the Companies to meet their
                          obligations hereunder.





                                    -  17  -
<PAGE>   23

the Company will deliver to the Documentation Agent an Officer's Certificate
specifying the nature and period of existence thereof and what action the
Company has taken, is taking or proposes to take with respect thereto.

         The Documentation Agent will promptly distribute to the Lenders,
originals (to the extent available) or copies of the financial statements and
reports, the Officer's Certificates and all other documents received by the
Documentation Agent from the Borrower pursuant to this Section 6.1.

         6.2     Inspection of Property and Books and Records.  The Companies
agree that they will permit the Agents, each Lender (with prior notice to the
Agents) and any Person designated by the Agents in writing, at Agents' (or
Lender's) expense, to visit and inspect any of the properties of the Company
and its Subsidiaries, to examine the corporate books and financial records of
the Companies and make copies thereof or extracts therefrom, and to discuss the
affairs, finances and accounts of any of such corporations with the principal
officers of each of the Companies and their respective independent public
accountants, all at such reasonable times and as often as Agents or the Lenders
may reasonably request.

         6.3     Covenant to Secure Notes Equally.  (a) The Companies agree
that if the Company or any Subsidiary shall create or assume any Lien of any
kind upon any of its property or assets, whether now owned or hereafter
acquired, other than Liens permitted by the provisions of Section 6.8 (unless
prior written consent to the creation or assumption thereof shall have been
obtained), they will make or cause to be made effective provisions whereby the
Notes will be secured by such Lien equally and ratably with any and all other
Debt thereby secured, as long as any such other Debt shall be so secured.

         (b)     The Companies agree not to become a party to, or otherwise be
subject to, any provision contained in any instrument evidencing indebtedness
of any of the Companies which imposes restrictions on the granting of Liens by
the Companies on otherwise unencumbered assets of the Companies as security for
the Notes, except as set forth herein.

         6.4     Guaranteed or Collateralized Obligations.  The Company agrees
that if it or any of its Subsidiaries incurs or permits to exist any Debt in
any event in excess of an aggregate principal amount equal to $10,000,000
guaranteed or collateralized (except as permitted by Sections 6.8(v) and
6.8(ix) hereof) in any other manner by any other Person (other than any
governmental entity, or other than in connection with (y) bonds, letters of
credit, letters of undertaking, or other instruments related to litigation, or
the avoidance thereof, involving the Company or its Subsidiaries, including the
release of assets of the Company or its Subsidiaries in connection with such
litigation, or (z) performance bonds,  surety bonds, letters of credit, bank
guaranties, and other instruments related to the conduct of the business of the
Company or its Subsidiaries, excluding any obligation for borrowed money), it
will simultaneously cause





                                    -  18  -
<PAGE>   24
such Person to execute and deliver to  the Lenders a guaranty agreement or
collateral agreement, as the case may be, in form and substance satisfactory to
the Lenders either (i) guaranteeing payment of the principal amount of the
Notes and any premium and interest thereon, which bears the same ratio to the
total unpaid principal amount of the Notes as the amount of such other
obligation which is guaranteed bears to the total unpaid principal amount of
such other obligation or (ii) collateralizing the Notes equally and ratably
with such other obligation, as the case may be.  Nothing contained in the
foregoing shall be deemed to permit the Companies to incur Liens to Persons
other than the Lenders in excess of those permitted by Section 6.8 hereof.

         6.5     Maintenance of Insurance.  Each Company agrees that it and
each Subsidiary will maintain, with responsible insurers, insurance with
respect to its properties and business against such casualties and
contingencies (including, but not limited to, public liability, larceny,
embezzlement or other criminal misappropriation, pollution and war risks) and
in such amounts as is customary in the case of similarly situated corporations
engaged in the same or similar businesses.

         6.6     Maintenance of Corporate Existence/Compliance with
Law/Preservation of Property.  Except as allowed under Sections 6.11 and 6.12,
each Company covenants that it and each Subsidiary will do or cause to be done
all things necessary to preserve, renew and keep in full force and effect the
corporate existence of such Company and its Subsidiaries and comply in all
material respects with all laws and regulations (including, without limitation,
laws and regulations relating to equal employment opportunity and employee
safety) applicable to it and its Subsidiaries, the failure with which to comply
is likely to materially adversely affect the business, operations or financial
condition of such Company and its Subsidiaries, taken as a whole; at all times
maintain, preserve and protect all material intellectual property of such
Company and its Subsidiaries, and preserve all the remainder of its material
property used or useful in the conduct of its business and keep the same in
good repair, working order and condition.  The Companies shall not enter into
business activities materially different from the nature of the business
activities of the Companies as of the date of this Agreement.

         6.7     Compliance with Environmental Laws.  Each of the Companies
will, and the Company will cause each of its Subsidiaries to, comply in a
timely fashion with, or operate pursuant to valid waivers of the provisions of,
all Environmental Requirements including, without limitation, requirements with
respect to the emission of wastewater effluent, solid and hazardous waste and
air pollution, and any  other applicable requirements for conducting, on a
timely basis, periodic tests and monitoring for contamination of ground water,
surface water, air and land and for biological toxicity of the aforesaid, and
comply with any applicable regulations (except to the extent such regulations
are waived by appropriate governmental authorities) of the Environmental
Protection Agency or other relevant federal, state or local governmental
authority, except where the failure to do so is not likely to materially
adversely affect the business, operations or financial condition of the Company
and the Subsidiaries, taken as a whole.  To the fullest extent permitted by
applicable law, each Company agrees to





                                    -  19  -
<PAGE>   25
indemnify and hold the Agents, the Lenders, their officers, agents and
employees harmless from any loss, liability, claim or expense that they may
incur or suffer as a result of a breach by the Company or any of the
Subsidiaries, as the case may be, of this covenant.  No Company shall be deemed
to have breached or violated this Section 6.7 if such Company or Subsidiary is
challenging in good faith by appropriate proceedings diligently pursued the
application or enforcement of such Environmental Requirements for which
adequate reserves have been established in accordance with generally accepted
accounting principles.

         6.8  Liens.  The Companies agree that they will not and will not
permit any Subsidiary to create, assume or suffer to exist any Lien upon any of
their respective property or assets, whether now owned or hereafter acquired
(whether or not provision is made for the equal and ratable securing of the
Credit in accordance with the provisions of Section 6.3) except:

              (i)         Liens for taxes (including ad valorem and property
                          taxes) not yet due or which are being contested in
                          good faith by appropriate proceedings;

             (ii)         Liens incidental to the conduct of their businesses
                          or the ownership of their property and assets which
                          were not incurred in connection with the borrowing of
                          money or the obtaining of advances of credit, and
                          which do not in the aggregate materially detract from
                          the value of their property or assets or materially
                          impair the use thereof in the operation of their
                          business;

            (iii)         presently existing Liens on property or assets of any
                          of the Subsidiaries to secure obligations of any of
                          such Subsidiaries to the Company or another
                          Subsidiary;

         Any notice or demand which, by any provision of this Agreement, is
required or permitted to be given or served by the Companies to or on Lenders
shall be deemed to have been sufficiently given and served for all purposes (if
mailed) three calendar days after being deposited, postage prepaid, in the
United States mail, registered or certified mail, or (if





                                    -  47  -

delivered by express courier) one calendar day after being delivered to such
courier, or (if delivered in person) the same day as delivery, in each case
addressed (until another address or addresses are given in writing by Lenders
to the Companies) to the Lenders at the addresses set forth on Exhibit B
hereto.


         11.5  Costs, Expenses and Taxes; Indemnification.  (a)  The Companies
shall pay on demand the reasonable out-of-pocket costs and expenses of the
Agents in connection with the negotiation, syndication, preparation, execution
and delivery of this Agreement and any amendments thereto or waivers thereof
which may be requested by the Companies, including the reasonable fees and
out-of-pocket expenses of legal counsel to Agents.  The Companies shall pay on
demand the reasonable out-of-pocket costs and expenses of the Agents and each
of the Lenders in connection with the enforcement of this Agreement and/or the
Notes and in connection with any amendments thereto or waivers thereof which
may be requested by the Companies during the continuance of, or to avoid, a
Default or Event of Default, including any amendments or waivers tantamount to
a refinancing, restructuring, or reorganization (whether or not under any
Bankruptcy Law).  The out-of-pocket costs and expenses referred to in the
previous sentence shall include the reasonable fees and out-of-pocket expenses
of any legal counsel retained by the Agents or by any Lender, and the
reasonable fees and out-of-pocket expenses of any independent public
accountants and other outside experts retained by the Agents on behalf of the
Lenders.  The Lenders agree that, with respect to the retention of separate
legal counsel for each Lender under such circumstances, each will consider in
good faith whether separate legal counsel is reasonably appropriate under the
policies of that Lender and, in any event, endeavor to avoid unreasonable
duplication of work effort by such legal counsel.  The Companies shall pay any
and all documentary and other taxes (other than income or gross receipts taxes
generally applicable to banks) and shall reimburse, hold harmless, and
indemnify the Agents and each Lender from and against any and all loss,
liability, or legal or other expense with respect to or resulting from any
delay in paying or failure to pay any tax, cost, expense, fee, or charge or
that any of them may suffer or incur by reason of the failure of the Companies
to perform any of its obligations under this Agreement or the Notes.  Any
amount payable to the Agents or any Lender under this Section shall bear
interest from the date of receipt of demand for payment at the Base Rate plus
one percent (1%).

         (b) The Companies shall indemnify each Agent and Lender, their
respective affiliates and the respective shareholders, directors, officers,
employees, agents and counsel of the foregoing (each an "Indemnitee") and hold
each Indemnitee harmless from and against any and all liabilities, losses,
damages, costs and expenses of any kind, including, without limitation, the
reasonable fees and disbursements of counsel, which may be incurred by such
Indemnitee in connection with any investigative, administrative or judicial
proceeding (whether or not such Indemnitee shall be designated a party thereto)
brought or threatened relating to or arising out of the Credit Facility or any
actual or proposed use of proceeds of the Loans hereunder; provided that no
Indemnitee shall  have the right to be indemnified hereunder for such





                                    -  48  -
<PAGE>   54
Indemnitee's own gross negligence or willful misconduct as determined by a
court of competent jurisdiction, or to the extent that such claim relates to
the breach by such Lender Indemnitee of its obligations under this Agreement.

         11.6    Foreign Lenders.  (a)  All payments by the Company under the
Credit Facility shall be made free and clear of and without deduction for or on
account of any present or future income, stamp, or other taxes, fees, duties,
withholding or other charges of any nature whatsoever imposed by any taxing
authority, excluding in the case of each Lender taxes imposed on or measured by
its net income or franchise taxes imposed in lieu of net income taxes by the
jurisdiction in which it is organized or through which it acts for purposes of
this Agreement.

         (b)     If as a result of any change in law (or the interpretation
thereof) after the Effective Date, any withholding or deduction from any
payment to be made to, or for the account of, a Lender by the Companies
hereunder is required in respect of any non-excluded taxes referred to in
Subsection (a) above pursuant to any applicable law, rule, or regulation, then
the Company will (i) pay to the relevant authority the full amount required to
be so withheld or deducted; (ii) to the extent available, promptly forward to
the Agent an official receipt or other documentation satisfactory to the
Documentation Agent evidencing such payment to such authority; and (iii) pay to
the Administrative Agent, for the account of each affected Lender, such
additional amount or amounts as are necessary to ensure that the net amount
actually received by such Lender will equal the full amount such Lender would
have received had no such withholding or deduction been required.  Each Lender
shall determine such additional amount or amounts payable to it (which
determination shall, in the absence of manifest error, be conclusive and
binding on the Company).  If a Lender becomes aware that any such withholding
or deduction from any payment to be made by the Company under the Credit
Facility is required, then such Lender shall promptly notify the Documentation
Agent and the Company thereof stating the reasons therefor and the additional
amount required to be paid under this Section, and such Lender shall execute
and deliver to the Documentation Agent and the Company such forms as it may be
required to execute and deliver pursuant to Subsection (c) hereof.  To the
extent that any such withholding or deduction results from the failure of a
Lender to provide a form required by Subsection (c) hereof, the Company shall
have no obligation to pay the additional amount required by clause (iii) above.
Anything in this Section notwithstanding, if any Lender elects to require
payment by the Company of any material amount under this Section, the Company
may, within 60 days after the date of receiving notice thereof and so long as
no Default shall have occurred and be continuing, elect to terminate such
Lender as a party to this Agreement; provided that, concurrently with such
termination, the Company shall (i) if the Documentation Agent and each of the
other Lenders shall consent, pay that Lender all principal, interest and fees
and other amounts owed to such Lender through such date of termination or (ii)
have arranged for another financial institution approved by the Documentation
Agent (such approval not to be unreasonably withheld) as of such date, to
become a substitute Lender for all purposes under this Agreement in the manner
provided for herein; provided further that, prior to substitution for any
Lender, the Company shall have given written notice to the Documentation





                                    -  49  -
<PAGE>   55
Agent of such intention and the Lenders shall have the option, but not the
obligation, for a period of 60 days after receipt of such notice, to increase
their Commitments in order to replace the affected Lender in lieu of such
substitution.

         (c)  With respect to each Lender which is organized under the laws of
a jurisdiction outside the United States, on the day of the initial borrowing
from each such Lender hereunder and from time to time thereafter if requested
by the Company or the Documentation Agent, such Lender shall provide the
Documentation Agent and the Company with the forms prescribed by the Internal
Revenue Service of the United States certifying as to such Lender's status for
purposes of determining exemption from United States withholding taxes with
respect to all payments to be made to such Lender hereunder or other documents
satisfactory to such Lender and Documentation Agent indicating that all
payments to be made to such Lender hereunder are not subject to United States
withholding tax.  Unless the Documentation Agent and the Company shall have
received such forms or such documents indicating that payments hereunder are
not subject to United States withholding tax, the Administrative Agent and the
Company shall withhold taxes from such payments at the applicable statutory
rate in the case of payments to or for any Lender organized under the laws of a
jurisdiction outside the United States.

         11.7  Severability.  Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining portions hereof or affecting the validity or
enforceability of such provision in any other jurisdiction.

         11.8  Counterparts.  This Agreement may be executed in as many
counterparts as may be deemed necessary or convenient, and by the different
parties hereto on separate counterparts, each of which, when so executed, shall
be deemed an original but all such counterparts shall constitute but one and
the same instrument.

         11.9  Law.  This Agreement and the Notes shall be contracts made under
and governed by the laws of the State of Louisiana.

         11.10  Successors.  This Agreement shall be binding upon the Companies
and Lenders, and their respective successors and assigns, and shall inure to
the benefit of the Companies and Lenders, and the successors and assigns of
Lenders.  The Companies shall not assign their rights or duties hereunder
without the consent of Lenders.

         11.11  Singular and Plural.  Words used herein in the singular, where
the context so permits, shall be deemed to include the plural and vice versa.
The definition of words in the singular herein shall apply to such words when
used in the plural where the context so permits and vice versa.

         11.12 Amendments.  No amendment or waiver of any provision of this
Agreement or consent to any departure therefrom by the Companies or Lenders
shall be effective unless the same shall be in writing and signed by the
Companies, the Agents and the Required Lenders, provided that, without the
written consent of all of the Lenders, no amendment to this Agreement shall (i)
change the maturity of any Note, or (ii) change the principal of or the rate or
time of payment of interest or any premium payable with respect to any Note, or
(iii) change the principal payment date of any installment of the Conversion
Term Notes or the Acquisition Term Notes, or (iv) increase the Commitments, or
(v) release any of the Companies, or affect the time, amount or allocation of
any required prepayments, or (vi) reduce the proportion of the Required Lenders
required with respect to any consent, or (vii) change the definition of
Required Lenders or amend this Section 11.12.  No course of dealing between any
of the Companies and the Lenders nor any delay in exercising any  rights
hereunder or under any Note shall operate as a waiver of any rights of any of
the Lenders.  In the case of a waiver or consent, such waiver or consent shall
be effective only in the specific instance and for the specific purpose for
which given.

         11.13  Entire Agreement.  This Agreement constitutes the entire
agreement between the parties and supersedes any and all prior agreements with
respect to the transactions contemplated hereby.

                          CHANGE OF CONTROL AGREEMENT

         This Change of Control Agreement ("the Agreement") between Tidewater,
Inc., a Delaware corporation (the "Company"), and William C. O'Malley (the
"Employee") is dated effective as of September 30, 1996 (the "Change of Control
Agreement Date").


                                   ARTICLE I
                                  DEFINITIONS

         1.1     AFFILIATE DEFINED.  "Affiliate" or "affiliated companies"
shall mean any company controlled by, controlling, or under common control
with, the Company.

         1.2     CAUSE DEFINED.  "Cause" shall mean:

                          (a)     the willful and continued failure of the
                 Employee to perform substantially the Employee's duties with
                 the Company or its affiliates (other than any such failure
                 resulting from incapacity due to physical or mental illness),
                 after a written demand for substantial performance is
                 delivered to the Employee by the Board of the Company which
                 specifically identifies the manner in which the Board believes
                 that the Employee has not substantially performed the
                 Employee's duties, or

                          (b)     the willful engaging by the Employee in
                 illegal conduct or gross misconduct.

For purposes of this provision, no act or failure to act, on the part of the
Employee, shall be considered "willful" unless it is done, or omitted to be
done, by the Employee in bad faith or without reasonable belief that the
Employee's action or omission was in the best interests of the Company or its
Affiliates.  Any act, or failure to act, based upon authority given pursuant to
a resolution duly adopted by the Board or upon the instructions of a senior
officer of the Company or based upon the advice of counsel for the Company or
its Affiliates shall be conclusively presumed to be done, or omitted to be
done, by the Employee in good faith and in the best interests of the Company or
its Affiliates.  The cessation of employment of the Employee shall not be
deemed to be for Cause unless his action or inaction meets the foregoing
standard and until there shall have been delivered to the Employee a copy of a
resolution duly adopted by the affirmative vote of not less than three-quarters
of the entire membership of the Board at a meeting of the Board called and held
for such purpose (after reasonable notice is provided to the Employee and the
Employee is given an opportunity, together with counsel, to be heard before the
Board), finding that, in the good faith opinion of the Board, the Employee is
guilty of the conduct described in subparagraph (a) or (b) above, and
specifying the particulars thereof in detail.

         1.3     CHANGE OF CONTROL DEFINED.  "Change of Control" shall mean:

                 (a)      the acquisition by any individual, entity or group
         (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities
         Exchange Act of 1934 of beneficial ownership (within the meaning of
         Rule 13d-3 promulgated under the Exchange Act) of more than 30% of the
         outstanding shares of the Company's Common Stock, $0.10 par value per
         share (the "Common Stock"); provided, however, that for purposes of
         this subsection (a), the following shall not constitute a Change of
         Control:

                          (i)     any acquisition of Common Stock directly from
                 the Company,

                          (ii)    any acquisition of Common Stock by the
                 Company,

                          (iii)   any acquisition of Common Stock by any
                 employee benefit plan (or related trust) sponsored or
                 maintained by the Company or any corporation controlled by the
                 Company, or

                          (iv)    any acquisition of Common Stock by any
                 corporation pursuant to a transaction that complies with
                 clauses (i), (ii) and (iii) of subsection (c) of this Section
                 1.3; or

                 (b)      individuals who, as of the Change of Control
         Agreement Date, constitute the Board (the "Incumbent Board") cease for
         any reason to constitute at least a majority of the Board; provided,
         however, that any individual becoming a director subsequent to the
         Change of Control Agreement Date whose election, or nomination for
         election by the Company's shareholders, was approved by a vote of at
         least a majority of the directors then comprising the Incumbent Board
         shall be considered a member of the Incumbent Board, unless such
         individual's initial assumption of office occurs as a result of an
         actual or threatened election contest with respect to the election or
         removal of directors or other actual or threatened solicitation of
         proxies or consents by or on behalf of a person other than the
         Incumbent Board; or

                 (c)      consummation of a reorganization, merger or
         consolidation, or sale or other disposition of all of substantially
         all of the assets of the Company (a "Business Combination"), in each
         case, unless, following such Business Combination,

                          (i)     all or substantially all of the individuals
                 and entities who were the beneficial owners of the Company's
                 outstanding common stock and the Company's voting securities
                 entitled to vote generally in the election of directors
                 immediately prior to such Business Combination have direct or
                 indirect beneficial ownership, respectively, of more than 50%
                 of the then outstanding shares of common stock, and more than
                 50% of the combined voting power of the then outstanding
                 voting securities entitled to vote generally in the election
                 of directors, of the corporation resulting from such Business
                 Combination (which, for purposes of this paragraph (i) and 
                 paragraphs (ii) and (iii), shall include a corporation which
                 as a result of such transaction controls the Company or all or
                 substantially all of the Company's assets either directly or
                 through one or more subsidiaries), and

                          (ii)    except to the extent that such ownership
                 existed prior to the Business Combination, no person
                 (excluding any corporation resulting from such Business
                 Combination or any employee benefit plan or related trust of
                 the Company or such corporation resulting from such Business
                 Combination) beneficially owns, directly or indirectly, 30% or
                 more of the then outstanding shares of common stock of the
                 corporation resulting from such Business Combination or 30% or
                 more of the combined voting power of the then outstanding
                 voting securities of such corporation, and

                          (iii)   at least a majority of the members of the
                 board of directors of the corporation resulting from such
                 Business Combination were members of the Incumbent Board at
                 the time of the execution of the initial agreement, or of the
                 action of the Board, providing for such Business Combination;
                 or

         complete liquidation or dissolution of the Company.

         1.4     COMPANY DEFINED.  As used in this Agreement, "Company" shall
mean the Company as defined above and any successor to or assignee of (whether
direct or indirect, by purchase, merger, consolidation or otherwise) all or
substantially all of the assets or business of the Company.

         1.5     DISABILITY DEFINED.  "Disability" shall mean a condition that
would entitle the Employee to receive benefits under the Company's long-term
disability insurance policy in effect at the time either because he is totally
disabled or partially disabled, as such terms are defined in the Company's
policy in effect as of the date of this Agreement or as similar terms are
defined in any successor policy.  If the Company has no long-term disability
plan in effect, "Disability" shall occur if (a) the Employee is rendered
incapable because of physical or mental illness of satisfactorily discharging
his duties and responsibilities to the Company for a period of 90 consecutive
days, (b) a duly qualified physician chosen by the Company and acceptable to
the Employee or his legal representatives so certifies in writing, and (c) the

         provide the Employee with the position, authority, duties and
         responsibilities at least commensurate in all material respects with
         the most significant of those held, exercised and assigned at any time
         during the 120-day period immediately preceding the Change of Control.
         The Employee's position, authority, duties and responsibilities after
         a Change of Control shall be considered commensurate in all material
         respects with Employee's position, authority, duties and
         responsibilities prior to a Change of Control if after the Change of
         Control Employee either holds (i) an equivalent position in the
         Company or, (ii) if the Company is controlled or will after the
         transaction be controlled by another company (directly or indirectly),
         an equivalent position in the ultimate parent company.

                 (b)      The assignment to the Employee of any duties
         inconsistent in any material respect with Employee's position
         (including status, offices, titles and reporting requirements),
         authority, duties or responsibilities as contemplated by Section
         3.1(b) of this Agreement, or any other action that results in a
         diminution in such position, authority, duties or responsibilities,
         excluding for this purpose an isolated, insubstantial and inadvertent
         action not taken in bad faith that is remedied within 10 days after
         receipt of written notice thereof from the Employee to the Company;

                 (c)      Any failure by the Company or its Affiliates to
         comply with any of the provisions of this Agreement, other than an
         isolated, insubstantial and inadvertent failure not occurring in bad
         faith that is remedied within 10 days after receipt of written notice
         thereof from the Employee to the Company;

                 (d)      The Company or its Affiliates requiring the Employee
         to be based at any office or location other than as provided in
         Section 3.1(b)(ii) hereof or requiring the Employee to travel on
         business to a substantially greater extent than required immediately
         prior to the Change of Control;

                 (e)      Any purported termination of the Employee's
         employment otherwise than as expressly permitted by this Agreement; or

                 (f)      Any failure by the Company to comply with and satisfy
         Sections 4.1(c) and (d) of this Agreement.

                                   ARTICLE II
                         STATUS OF EMPLOYMENT AGREEMENT

         Notwithstanding any provisions thereof, after a Change of Control,
this Agreement supersedes the agreement dated as of June 13, 1994 between the
Company and the Employee or any subsequent employment agreement between
Employee and the Company that so provides (the "Employment Agreement"), except
with respect to those provisions of the Employment Agreement that are made a
part of and specifically incorporated by reference herein.  Upon a Change of
Control of the Company, as defined herein, or upon a "Change of Control of the
Company" as defined in the Employment Agreement, the Employee shall be entitled
to the benefits provided herein and not to the benefits provided therein.

                                  ARTICLE III
                           CHANGE OF CONTROL BENEFIT

         3.1      EMPLOYMENT TERM AND CAPACITY AFTER CHANGE OF CONTROL.  (a)
This Agreement shall commence on the date hereof and continue in effect through
December 31, 1997; provided, however, that commencing on January 1, 1998 and
each January 1 thereafter, the term of this Agreement shall automatically be
extended for one additional year unless, not later than September 30 of the
preceding year, the Company shall have given notice that it does not wish to
extend this Agreement; provided, further, that notwithstanding any such notice
by the Company not to extend, 





                                      -4-
<PAGE>   5
if a Change of Control of the Company shall have occurred during the original
or extended term of this Agreement, this Agreement shall continue in effect
through the second anniversary of the Change of Control (such period following
a Change of Control being referred to herein as the "Employment Term"), subject
to any earlier termination of Employee's status as an employee pursuant to this
Agreement.

         (b)     After a Change of Control and during the Employment Term, (i)
the Employee's position (including status, offices, titles and reporting
requirements) authority, duties and responsibilities shall be at least
commensurate in all material respects with the most significant of those held,
exercised and assigned at any time during the 120-day period immediately
preceding the Change of Control and (ii) the Employee's service shall be
performed during normal business hours at the Company's principal executive
office, at its location at the time of the Change of Control, or the location
where the Employee was employed immediately preceding the Change of Control or
any relocation of the Company's principal executive office to a location that
is not more than 35 miles from such current location.  Employee's position,
authority, duties and responsibilities after a Change of Control shall not be
considered commensurate in all material respects with Employee's position,
authority, duties and responsibilities prior to a Change of Control unless
after the Change of Control Employee holds (x) an equivalent position in the
Company or, (y) if the Company is controlled or will after the transaction be
controlled by another company (directly or indirectly), an equivalent position
in the ultimate parent company.

         3.2     COMPENSATION AND BENEFITS.  During the Employment Term,
Employee shall be entitled to the following compensation and benefits:

                 (a)      Base Salary.  The Employee shall receive an annual
         base salary ("Base Salary"), which shall be paid at a monthly rate, at
         least equal to 12 times the highest monthly base salary that was paid
         or is payable, including any base salary which has been earned but
         deferred by the Employee, by the Company and its affiliated companies
         with respect to any month in the 12-month period ending with the month
         that immediately precedes the month in which the Change of Control
         occurs.  During the Employment Term, the Base Salary shall be reviewed
         at such time as the Company undertakes a salary review of its other
         executive officers, and, to the extent that salary increases are
         granted to such other executive officers, the Employee shall be
         granted a salary increase commensurate with his peer executives of the
         Company and its affiliated companies for the year of determination.
         Any increase in Base Salary shall not serve to limit or reduce any
         other obligation to the Employee under this Agreement.  Base Salary
         shall not be reduced after any such increase and the term Base Salary
         as utilized in this Agreement shall refer to Base Salary as so
         increased.

                 (b)      Annual Bonus.  In addition to Base Salary, the
         Employee shall be awarded, for each fiscal year ending during the
         Employment Term, an annual bonus (the "Bonus") in cash in an amount at
         least equal to the average of the annual bonus paid to the Employee
         with respect to the three fiscal years immediately preceding the year
         in which the Change of Control occurs under the Company's annual bonus
         plan, or any comparable bonus under a successor plan.  Each such Bonus
         shall be paid no later than the end of the third month of the 




                                      -5-
<PAGE>   6
         fiscal year for which the Bonus is awarded, unless the Employee shall  
         elect to defer the receipt of such Bonus.

                 (c)      Fringe Benefits.  The Employee shall be entitled to
         fringe benefits (including, but not limited to, automobile allowance,
         reimbursement for membership dues, and air travel) commensurate with
         those provided to other peer employees of the Company and its
         affiliated companies.

                 (d)      Expenses.  The Employee shall be entitled to receive
         prompt reimbursement for all reasonable expenses incurred by the
         Employee in accordance with the most favorable agreements, policies,
         practices and procedures of the Company and its affiliated companies
         in effect for the Employee at any time during the 120- day period
         immediately preceding the Change of Control or, if more favorable to
         the Employee, as in effect generally at any time thereafter with
         respect to other peer employees of the Company and its affiliated
         companies.

                 (e)      Incentive, Savings and Retirement Plans.  The
         Employee shall be entitled to participate in all incentive, savings
         and retirement plans, practices, policies and programs applicable
         generally to other peer employees of the Company and its affiliated
         companies, but in no event shall such plans, practices, policies and
         programs provide the Employee with incentive opportunities (measured
         with respect to both regular and special incentive opportunities, to
         the extent, if any, that such distinction is applicable), savings
         opportunities and retirement benefit opportunities, in each case, less
         favorable than the most favorable of those provided by the Company and
         its affiliated companies for the Employee under any agreements, plans,
         practices, policies and programs as in effect at any time during the
         120-day period immediately preceding the Change of Control, including
         any agreement by the Company to provide retirement benefits not less
         in amount than the retirement benefits to which the Employee would
         have been entitled under the terms of any qualified defined benefit
         pension plans of his immediate prior employer, or, if more favorable
         to the Employee, those provided generally at any time after the Change
         of Control to other peer employees of the Company and its affiliated
         companies.

                 (f)      Welfare Benefit Plans.  The Employee and/or the
         Employee's family, as the case may be, shall be eligible for
         participation in and shall receive all benefits under welfare benefit
         plans, practices, policies and programs provided by the Company and
         its affiliated companies (including, without limitation, medical,
         prescription, dental, disability, employee life, group life,
         accidental death and travel accident insurance plans and programs) to
         the extent applicable generally to other peer employees of the Company
         and its affiliated companies, but in no event shall such plans,
         practices, policies and programs provide the Employee with benefits,
         in each case, less favorable than the most favorable of any
         agreements, plans, practices, policies and programs in effect for the
         Employee at any time during the 120-day period immediately preceding
         the Change of Control or, if more favorable to the Employee, those
         provided generally at any time after the Change of Control to other
         peer employees of the Company and its affiliated companies.

         



                                      -6-

                  (g)      Office and Support Staff.  The Employee shall be
         entitled to an office or offices of a size and with furnishings and
         other appointments, and to exclusive personal secretarial and other
         assistance, commensurate with those provided to other peer employees   
         of the Company and its affiliated companies.

                 (h)      Vacation.  The Employee shall be entitled to paid
         vacation in accordance with the most favorable agreements, plans,
         policies, programs and practices of the Company and its affiliated
         companies as in effect for the Employee at any time during the 120-day
         period immediately preceding the Change of Control or, if more
         favorable to the Employee, as in effect generally at any time
         thereafter with respect to other peer employees of the Company and its
         affiliated companies.

                 (i)      Indemnification.  If in connection with any agreement
         related to a transaction that will result in a Change of Control of
         the Company, an undertaking is made to provide the Board of Directors
         with rights to indemnification from the Company (or any other party to
         such agreement), the Employee shall, by virtue of this Agreement, be
         entitled to the same rights to indemnification as are provided to the
         Board of Directors pursuant to such agreement.  Otherwise, the
         Employee shall be entitled to indemnification rights on terms no less
         favorable to Employee than those available under the Certificate of
         Incorporation, bylaws or resolutions of the Company at any time after
         the change of control to other peer employees of the Company.  Such
         indemnification rights shall be with respect to all claims, actions,
         suits or proceedings to which the Employee is or is threatened to be
         made a party that arise out of or are connected to his services at any
         time prior to the termination of his employment, without regard to
         whether such claims, actions, suits or proceedings are made, asserted
         or arise during or after the Employment Term.

                 (j)      Directors and Officers Insurance.  If in connection
         with any agreement related to a transaction that will result in a
         Change of Control of the Company, an undertaking is made to provide
         the Board of Directors of the Company with continued coverage
         following the Change of Control under one or more directors and
         officers liability insurance policies, then the Employee shall, by
         virtue of this Agreement, be entitled to the same rights to continued
         coverage under such insurance policies as are provided to the Board of
         Directors.  Otherwise, the Company shall agree to cover Employee under
         any of its director and officers liability insurance policies on terms
         provided generally at any time after the Change of Control to other
         peer employees of the Company.

         3.3     OBLIGATIONS UPON TERMINATION AFTER A CHANGE OF CONTROL.

                 (a)      Termination by Company for Reasons other than Death,
         Disability or Cause or by Employee for Good Reason.  If, after a
         Change of Control and during the Employment Term, the Company
         terminates the Employee's employment other than for Cause, death or
         Disability, or the Employee terminates employment for Good Reason,

                          (i)     the Company shall pay to the Employee in a
                 lump sum in cash within five business days of the date of
                 termination an amount equal to three times the sum





                                      -7-

<PAGE>   8
                 of (i) the amount of Base Salary in effect at the date of      
                 termination, plus (ii) the greater of (x) the average of the
                 annual bonuses paid or to be paid to the Employee with respect
                 to the immediately preceding three fiscal years or (y) the
                 target Bonus for which the Employee is eligible for the
                 12-month period in which the date of termination occurs, as
                 such target bonus has been established by the Company for such
                 year;
        
                          (ii)    for a period of thirty-six (36) months
                 following the date of termination of employment (the
                 "Continuation Period"), the Company shall at its expense
                 continue on behalf of the Employee and his dependents and
                 beneficiaries the life insurance, disability, medical, dental
                 and hospitalization benefits provided (x) to the Employee at
                 any time during the 120-day period prior to the Change in
                 Control or at any time thereafter or (y) to other similarly
                 situated executives who continue in the employ of the Company
                 during the Continuation Period. The coverage and benefits
                 (including deductibles and costs) provided in this Section
                 2.3(a)(ii) during the Continuation Period shall be no less
                 favorable to the Employee and his dependents and
                 beneficiaries, than the most favorable of such coverages and
                 benefits during any of the periods referred to in clauses (x)
                 or (y) above.  In addition, if Employee has reached age 52 and
                 has completed seven years of service at the time of a Change
                 of Control, Employee shall automatically become vested in the
                 post-retirement benefits provided under the Tidewater Group
                 Welfare Benefits Plan (the "GWB Plan") and be entitled to
                 receive, following termination of employment with the Company,
                 all benefits that would be payable to Employee under the GWB
                 Plan or any successor plan of the Company or its affiliated
                 companies had the Employee retired from employment with the
                 Company or one of its affiliated companies on the later of the
                 third anniversary of the Change of Control or the Employee's
                 date of retirement (as defined in the GWB Plan) from
                 employment with the Company.  The Company's obligation
                 hereunder with respect to the foregoing benefits shall be
                 limited to the extent that the Employee obtains any such
                 benefits pursuant to a subsequent employer's benefit plans, in
                 which case the Company may reduce the coverage of any benefits
                 it is required to provide the Employee hereunder as long as
                 the aggregate coverages and benefits of the combined benefit
                 plans is no less favorable to the Employee than the coverages
                 and benefits required to be provided hereunder.  The Employee
                 will be eligible for coverage under the Consolidated Omnibus
                 Budget Reconciliation Act at the end of the Continuation
                 Period or earlier cessation of the Company's obligation
                 hereunder.

                          (iii)   the Employee shall immediately become fully
                 (100%) vested in his benefit under each supplemental or excess
                 retirement plan of the Company in which the Employee was a
                 participant, including, but not limited to the Tidewater, Inc.
                 Supplemental Executive Retirement Plan (the "SERP"), the
                 Supplemental Plan and any successor plans;

                          (iv)    the Company shall contribute to the trust
                 established in connection with the SERP and the Supplemental
                 Savings Plan (the "Trust") for the Employee's





                                     -8-
<PAGE>   9
                 account in cash within five business days of the date of
                 termination of employment an amount equal to the then present
                 value of the actuarial equivalent of the additional benefits,
                 if any, to which the Employee would be entitled under the
                 Tidewater, Inc. Pension Plan, the SERP and any other qualified
                 defined benefit plan maintained by the Company and covering
                 the Employee, regardless of the vesting requirements thereof,
                 or any agreement between the Company and the Employee with
                 respect to retirement benefits that is otherwise provided for
                 in the Employment Agreement (such retirement benefit agreement
                 being made a part hereof and specifically incorporated by
                 reference herein), if the Employee had continued to be
                 employed by the Company until the third anniversary of the
                 Change of Control.

                          (v)     the Company shall contribute to the
                 Supplemental Savings Plan trust for the Employee's account in
                 cash within five business days of the date of termination of
                 employment an amount equal to the amount of employer
                 contributions that would have been made on the Employees's
                 behalf if the Employee had continued to participate in the
                 Company's Savings Plan, the Company's Supplemental Savings
                 Plan and any other qualified or non-qualified defined
                 contribution plan maintained by the Company until the third
                 anniversary of the Change of Control.  Such contribution
                 shall, in the case of a qualified plan, be calculated as if
                 the Employee were fully vested and participating to the
                 maximum extent permitted by such plan and, in the case of a
                 non-qualified plan, be calculated on the same basis as the
                 Employee was participating in such plans and, in all cases, be
                 calculated on the basis of the Employee's annual salary rate
                 at the time of the Change of Control.

                          (vi)    to the extent that Employee is not fully
                 vested in his accrued benefits under the Pension Plan, the
                 Savings Plan or any other qualified plan maintained by the
                 Company, at the time of termination of employment, the Company
                 shall contribute to the Trust, within five business days of
                 the date of termination of employment, an amount in cash equal
                 to the unvested but accrued benefits under such plans as of
                 the date of termination of employment.

         Any contributions by the Company to the Trust as provided herein shall
         be distributed at such time as shall be elected by the Employee at the
         time of execution of this Agreement, except that amounts relating to
         services previously provided shall be distributed in accordance with
         the provisions of the plans or the related participant elections to
         which such contributions relate.  The benefits provided in this
         Section 3.3(a) shall be without regard to any amendment to any plans
         made after the Change of Control but prior to Employee's date of
         termination of employment, which amendment adversely affects in any
         manner the computation of benefits under such plans.

                 (b)      Death.  If, after a Change of Control and during the
         Employment Term, the Employee's status as an employee is terminated by
         reason of the Employee's death, this Agreement shall terminate without
         further obligation to the Employee's legal representatives (other than
         those already accrued to the Employee), other than the obligation to
         make any payments due pursuant to employee benefit plans maintained by
         the Company or its 




                                      -9-
<PAGE>   10
         affiliated companies and any death benefits to
         which the Employee is entitled under any Employment Agreement in
         effect immediately prior to the Change of Control (the death benefits
         provided by such Employment Agreement being made a part hereof and
         specifically incorporated by reference herein).
                            
                 (c)      Disability.  If, after a Change of Control and during
         the Employment Term, the Employee's status as an employee is
         terminated by reason of Employee's Disability, this Agreement shall
         terminate without further obligation to the Employee (other than those
         already accrued to the Employee), other than the obligation to make
         any payments due pursuant to employee benefit plans maintained by the
         Company or its affiliated companies and any disability benefits to
         which Employee is entitled under any Employment Agreement in effect
         immediately prior to the Change of Control (the disability provisions
         of such Employment Agreement being made a part hereof and specifically
         incorporated by reference herein).

                 (d)      Cause.  If, after a Change of Control and during the
         Employment Term, the Employee's status as an employee is terminated by
         the Company for Cause, this Agreement shall terminate without further
         obligation to the Employee other than for obligations imposed by law
         and obligations imposed pursuant to any employee benefit plan
         maintained by the Company or its affiliated companies.

                 (e)      Voluntary Termination.  If, after a Change of Control
         and during the Employment Term, the Employee voluntarily terminates
         his employment with the Company other than for Good Reason, this
         Agreement shall terminate without further obligation to the Employee
         other than for obligations imposed by law and obligations imposed
         pursuant to any employee benefit plan maintained by the Company or its
         affiliated companies.

         3.4     ACCRUED OBLIGATIONS AND OTHER BENEFITS.  It is the intent of
this Agreement that upon termination of employment for any reason following a
Change of Control the Employee be entitled to receive promptly, and in addition
to any other benefits specifically provided, (a) the Employee's Base Salary
through the date of termination to the extent not theretofore paid, (b) any
accrued vacation pay, to the extent not theretofore paid, and (c) any other
amounts or benefits required to be paid or provided or which the Employee is
entitled to receive under any plan, program, policy practice or agreement of
the Company.

         3.5     STOCK OPTIONS AND RESTRICTED STOCK.  The foregoing benefits
are intended to be in addition to the value of any options to acquire Common
Stock of the Company or restricted stock the exercisability or vesting of which
is accelerated pursuant to the terms of any stock option, incentive or other
similar plan or agreement heretofore or hereafter adopted by the Company.

         3.6     CERTAIN ADDITIONAL PAYMENTS.  The Employee shall be entitled
to such payments from the Company related to any excise tax as a result of the
"excess parachute payment" provisions of section 4999 of the Internal Revenue
Code of 1986, as amended  (or any successor thereto), as were provided for
under any Employment Agreement in effect immediately prior to the Change of



                                     -10-


<PAGE>   11

Control (the obligations of the Company to make such payments being made a part
hereof and specifically incorporated by reference herein).


         3.7     LEGAL FEES.  The Company agrees to pay as incurred, to the
full extent permitted by law, all legal fees and expenses which the Employee
may reasonably incur as a result of any contest (regardless of the outcome
thereof) by the Company, the Employee or others of the validity or
enforceability of, or liability under, any provision of this Agreement
(including as a result of any contest by the Employee about the amount or
timing of any payment pursuant to this Agreement.)

         3.8     SET-OFF; MITIGATION.  After a Change of Control, the Company's
and its Affiliates' obligations to make the payments provided for in this
Agreement and otherwise to perform its obligations hereunder shall not be
affected by any set-off, counterclaim, recoupment, defense or other claim,
right or action which the Company or its Affiliates may have against the
Employee or others; except that to the extent the Employee accepts other
employment in connection with which he is provided health insurance benefits,
the Company shall only be required to provide health insurance benefits to the
extent the benefits provided by the Employee's employer are less favorable than
the benefits to which he would otherwise be entitled hereunder.  It is the
intent of this Agreement that in no event shall the Employee be obligated to
seek other employment or take any other action by way of mitigation of the
amounts payable to the Employee under any of the provisions of this Agreement.

         3.9     OUTPLACEMENT ASSISTANCE.  Upon any termination of employment
of the Employee other than for Cause within three years following a Change of
Control, the Company shall provide to the Employee outplacement assistance by a
reputable firm specializing in such services for the period beginning with the
termination of employment and ending two years following the Change of Control.

                 (c)      The Company shall require any successor to or

(i) to assume unconditionally and expressly this Agreement and (ii) to agree to

succession occurred, such assumption to be set forth in a writing reasonably
satisfactory to the Employee.

control or that after the transaction will control (directly or indirectly) the

                          CHANGE OF CONTROL AGREEMENT


         This Change of Control Agreement ("the Agreement") between Tidewater,
Inc., a Delaware corporation (the "Company"), and Ken C. Tamblyn (the
"Employee") is dated effective as of September 30, 1996 (the "Change of Control
Agreement Date").


                                   ARTICLE I
                                  DEFINITIONS

         1.1     AFFILIATE DEFINED.  "Affiliate" or "affiliated companies"
shall mean any company controlled by, controlling, or under common control
with, the Company.

         1.2     CAUSE DEFINED.  "Cause" shall mean:

                          (a)     the willful and continued failure of the
                 Employee to perform substantially the Employee's duties with
                 the Company or its affiliates (other than any such failure
                 resulting from incapacity due to physical or mental illness),
                 after a written demand for substantial performance is
                 delivered to the Employee by the Board of the Company which
                 specifically identifies the manner in which the Board believes
                 that the Employee has not substantially performed the
                 Employee's duties, or

                          (b)     the willful engaging by the Employee in
                 illegal conduct or gross misconduct.
 
For purposes of this provision, no act or failure to act, on the part of the
Employee, shall be considered "willful" unless it is done, or omitted to be
done, by the Employee in bad faith or without reasonable belief that the
Employee's action or omission was in the best interests of the Company or its
Affiliates.  Any act, or failure to act, based upon authority given pursuant to
a resolution duly adopted by the Board or upon the instructions of a senior
officer of the Company or based upon the advice of counsel for the Company or
its Affiliates shall be conclusively presumed to be done, or omitted to be
done, by the Employee in good faith and in the best interests of the Company or
its Affiliates.  The cessation of employment of the Employee shall not be
deemed to be for Cause unless his action or inaction meets the foregoing
standard and until there shall have been delivered to the Employee a copy of a
resolution duly adopted by the affirmative vote of not less than three-quarters
of the entire membership of the Board at a meeting of the Board called and held
for such purpose (after reasonable notice is provided to the Employee and the
Employee is given an opportunity, together with counsel, to be heard before the
Board), finding that, in the good faith opinion of the Board, the Employee is
guilty of the conduct described in subparagraph (a) or (b) above, and
specifying the particulars thereof in detail.

         1.3      CHANGE OF CONTROL DEFINED.  "Change of Control" shall mean:

                 (a)      the acquisition by any individual, entity or group
         (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities
         Exchange Act of 1934 of beneficial ownership (within the meaning of
         Rule 13d-3 promulgated under the Exchange Act) of more than 30% of the
         outstanding shares of the Company's Common Stock, $0.10 par value per
         share (the "Common Stock"); provided, however, that for purposes of
         this subsection (a), the following shall not constitute a Change of
         Control:

                          (i)     any acquisition of Common Stock directly from
                 the Company,

                          (ii)    any acquisition of Common Stock by the
                 Company,

                          (iii)   any acquisition of Common Stock by any
                 employee benefit plan (or related trust) sponsored or
                 maintained by the Company or any corporation controlled by the
                 Company, or

                          (iv)    any acquisition of Common Stock by any
                 corporation pursuant to a transaction that complies with
                 clauses (i), (ii) and (iii) of subsection (c) of this Section
                 1.3; or

                 (b)      individuals who, as of the Change of Control
         Agreement Date, constitute the Board (the "Incumbent Board") cease for
         any reason to constitute at least a majority of the Board; provided,
         however, that any individual becoming a director subsequent to the
         Change of Control Agreement Date whose election, or nomination for
         election by the Company's shareholders, was approved by a vote of at
         least a majority of the directors then comprising the Incumbent Board
         shall be considered a member of the Incumbent Board, unless such
         individual's initial assumption of office occurs as a result of an
         actual or threatened election contest with respect to the election or
         removal of directors or other actual or threatened solicitation of
         proxies or consents by or on behalf of a person other than the
         Incumbent Board; or

                 (c)      consummation of a reorganization, merger or
         consolidation, or sale or other disposition of all of substantially
         all of the assets of the Company (a "Business Combination"), in each
         case, unless, following such Business Combination,

                          (i)     all or substantially all of the individuals
                 and entities who were the beneficial owners of the Company's
                 outstanding common stock and the Company's voting securities
                 entitled to vote generally in the election of directors
                 immediately prior to such Business Combination have direct or
                 indirect beneficial ownership, respectively, of more than 50%
                 of the then outstanding shares of common stock, and more than
                 50% of the combined voting power of the then outstanding
                 voting securities entitled to vote generally in the election
                 of directors, of the corporation resulting from such Business
                 Combination (which, for purposes of this paragraph (i)



                                     -2-

<PAGE>   3
                 and paragraphs (ii) and (iii), shall include a corporation
                 which as a result of such transaction controls the Company or
                 all or substantially all of the Company's assets either
                 directly or through one or more subsidiaries), and
        
                          (ii)    except to the extent that such ownership
                 existed prior to the Business Combination, no person
                 (excluding any corporation resulting from such Business
                 Combination or any employee benefit plan or related trust of
                 the Company or such corporation resulting from such Business
                 Combination) beneficially owns, directly or indirectly, 30% or
                 more of the then outstanding shares of common stock of the
                 corporation resulting from such Business Combination or 30% or
                 more of the combined voting power of the then outstanding
                 voting securities of such corporation, and

                          (iii)   at least a majority of the members of the
                 board of directors of the corporation resulting from such
                 Business Combination were members of the Incumbent Board at
                 the time of the execution of the initial agreement, or of the
                 action of the Board, providing for such Business Combination;
                 or

                 (d)      approval by the shareholders of the Company of a
         complete liquidation or dissolution of the Company.

         1.4     COMPANY DEFINED.  As used in this Agreement, "Company" shall
mean the Company as defined above and any successor to or assignee of (whether
direct or indirect, by purchase, merger, consolidation or otherwise) all or
substantially all of the assets or business of the Company.

         1.5     DISABILITY DEFINED.  "Disability" shall mean a condition that
would entitle the Employee to receive benefits under the Company's long-term
disability insurance policy in effect at the time either because he is totally
disabled or partially disabled, as such terms are defined in the Company's
policy in effect as of the date of this Agreement or as similar terms are
defined in any successor policy.  If the Company has no long-term disability
plan in effect, "Disability" shall occur if (a) the Employee is rendered
incapable because of physical or mental illness of satisfactorily discharging
his duties and responsibilities to the Company for a period of 90 consecutive
days, (b) a duly qualified physician chosen by the Company and acceptable to
the Employee or his legal representatives so certifies in writing, and (c) the
Board determines that the Employee has become disabled.

         1.6     GOOD REASON DEFINED.  "Good Reason" shall mean:

                 (a)      Any failure of the Company or its Affiliates to
         provide the Employee with the position, authority, duties and
         responsibilities at least commensurate in all material respects with
         the most significant of those held, exercised and assigned at any time
         during the 120-day period immediately preceding the Change of Control.
         The Employee's position, authority, duties and responsibilities after
         a Change of Control shall be considered commensurate in all material
         respects with Employee's position, authority, duties and

                                     -3-


<PAGE>   4
         responsibilities prior to a Change of Control if after the Change of
         Control Employee either holds (i) an equivalent position in the Company
         or, (ii) if the Company is controlled or will after the transaction be
         controlled by another company (directly or indirectly), an equivalent
         position in the ultimate parent company.
        
                 (b)      The assignment to the Employee of any duties
         inconsistent in any material respect with Employee's position
         (including status, offices, titles and reporting requirements),
         authority, duties or responsibilities as contemplated by Section
         3.1(b) of this Agreement, or any other action that results in a
         diminution in such position, authority, duties or responsibilities,
         excluding for this purpose an isolated, insubstantial and inadvertent
         action not taken in bad faith that is remedied within 10 days after
         receipt of written notice thereof from the Employee to the Company;

                 (c)      Any failure by the Company or its Affiliates to
         comply with any of the provisions of this Agreement, other than an
         isolated, insubstantial and inadvertent failure not occurring in bad
         faith that is remedied within 10 days after receipt of written notice
         thereof from the Employee to the Company;

                 (d)      The Company or its Affiliates requiring the Employee
         to be based at any office or location other than as provided in
         Section 3.1(b)(ii) hereof or requiring the Employee to travel on
         business to a substantially greater extent than required immediately
         prior to the Change of Control;

                 (e)      Any purported termination of the Employee's
         employment otherwise than as expressly permitted by this Agreement; or

                 (f)      Any failure by the Company to comply with and satisfy
         Sections 4.1(c) and (d) of this Agreement.

                                   ARTICLE II
                     STATUS OF CHANGE OF CONTROL AGREEMENTS

         Notwithstanding any provisions thereof, this Agreement supersedes the
agreement dated October 8, 1986 between the Company and the Employee that
provided for certain severance benefits in the event of a Change of Control of
the Company, as defined therein.

                                  ARTICLE III
                           CHANGE OF CONTROL BENEFIT

         3.1      EMPLOYMENT TERM AND CAPACITY AFTER CHANGE OF CONTROL.  (a)
This Agreement shall commence on the date hereof and continue in effect through
December 31, 1997; provided, however, that commencing on January 1, 1998 and
each January 1 thereafter, the term of this Agreement shall automatically be
extended for one additional year unless, not later than September 30 of the
preceding year, the Company shall have given notice that it does not wish to
extend this



                                     -4-

Agreement; provided, further, that notwithstanding any such notice by the
Company not to extend, if a Change of Control of the Company shall have occurred
during the original or extended term of this Agreement, this Agreement shall
continue in effect through the second anniversary of the Change of Control (such
period following a Change of Control being referred to herein as the "Employment
Term"), subject to any earlier termination of Employee's status as an employee
pursuant to this Agreement.

                 (b)     After a Change of Control and during the Employment
         Term, (i) the Employee's position (including status, offices, titles
         and reporting requirements), authority, duties and responsibilities
         shall be at least commensurate in all material respects with the most
         significant of those held, exercised and assigned at any time during
         the 120-day period immediately preceding the Change of Control and (ii)
         the Employee's service shall be performed during normal business hours
         at the Company's principal executive office, at its location at the
         time of the Change of Control, or the location where the Employee was
         employed immediately preceding the Change of Control or any relocation
         of the Company's principal executive office to a location that is not
         more than 35 miles from such current location.  Employee's position,
         authority, duties and responsibilities after a Change of Control shall
         not be considered commensurate in all material respects with Employee's
         position, authority, duties and responsibilities prior to a Change of
         Control unless after the Change of Control Employee holds (x) an
         equivalent position in the Company or, (y) if the Company is controlled
         or will after the transaction be controlled by another company
         (directly or indirectly), an equivalent position in the ultimate parent
         company.
        
         3.2     COMPENSATION AND BENEFITS.  During the Employment Term,
Employee shall be entitled to the following compensation and benefits:

                 (a)      Base Salary.  The Employee shall receive an annual
         base salary ("Base Salary"), which shall be paid at a monthly rate, at
         least equal to 12 times the highest monthly base salary that was paid
         or is payable, including any base salary which has been earned but
         deferred by the Employee, by the Company and its affiliated companies
         with respect to any month in the 12-month period ending with the month
         that immediately precedes the month in which the Change of Control
         occurs.  During the Employment Term, the Base Salary shall be reviewed
         at such time as the Company undertakes a salary review of its other
         executive officers, and, to the extent that salary increases are
         granted to such other executive officers, the Employee shall be
         granted a salary increase commensurate with his peer executives of the
         Company and its affiliates.  Any increase in Base Salary shall not
         serve to limit or reduce any other obligation to the Employee under
         this Agreement.  Base Salary shall not be reduced after any such
         increase and the term Base Salary as utilized in this Agreement shall
         refer to Base Salary as so increased.

                 (b)      Annual Bonus.  In addition to Base Salary, the
         Employee shall be awarded, for each fiscal year ending during the
         Employment Term, an annual bonus (the "Bonus") in cash in an amount at
         least equal to the average of the annual bonuses paid to the Employee
         with respect to the three fiscal years that immediately precede the
         year in which the Change of Control occurs under the Company's annual
         bonus plan, or any comparable bonus under


                                     -5-



<PAGE>   6

         a successor plan.  Each such Bonus shall be paid no later than the end
         of the third month of the fiscal year next following the fiscal year
         for which the Bonus is awarded, unless the Employee shall elect to
         defer the receipt of such Bonus.

                 (c)      Fringe Benefits.  The Employee shall be entitled to
         fringe benefits (including, but not limited to, automobile allowance,
         reimbursement for membership dues, and air travel) commensurate with
         those provided to other peer executive officers of the Company and its
         affiliated companies.

                 (d)      Expenses.  The Employee shall be entitled to receive
         prompt reimbursement for all reasonable expenses incurred by the
         Employee in accordance with the most favorable agreements, policies,
         practices and procedures of the Company and its affiliated companies
         in effect for the Employee at any time during the 120- day period
         immediately preceding the Change of Control or, if more favorable to
         the Employee, as in effect generally at any time thereafter with
         respect to other peer employees of the Company and its affiliated
         companies.

                 (e)      Incentive, Savings and Retirement Plans.  The
         Employee shall be entitled to participate in all incentive, savings
         and retirement plans, practices, policies and programs applicable
         generally to other peer employees of the Company and its affiliated
         companies, but in no event shall such plans, practices, policies and
         programs provide the Employee with incentive opportunities (measured
         with respect to both regular and special incentive opportunities, to
         the extent, if any, that such distinction is applicable), savings
         opportunities and retirement benefit opportunities, in each case, less
         favorable than the most favorable of those provided by the Company and
         its affiliated companies for the Employee under any agreements, plans,
         practices, policies and programs as in effect at any time during the
         120-day period immediately preceding the Change of Control or, if more
         favorable to the Employee, those provided generally at any time after
         the Change of Control to other peer employees of the Company and its
         affiliated companies.

                 (f)      Welfare Benefit Plans.  The Employee and/or the
         Employee's family, as the case may be, shall be eligible for
         participation in and shall receive all benefits under welfare benefit
         plans, practices, policies and programs provided by the Company and
         its affiliated companies (including, without limitation, medical,
         prescription, dental, disability, employee life, group life,
         accidental death and travel accident insurance plans and programs) to
         the extent applicable generally to other peer employees of the Company
         and its affiliated companies, but in no event shall such plans,
         practices, policies and programs provide the Employee with benefits,
         in each case, less favorable than the most favorable of any
         agreements, plans, practices, policies and programs in effect for the
         Employee at any time during the 120-day period immediately preceding
         the Change of Control or, if more favorable to the Employee, those
         provided generally at any time after the Change of Control to other
         peer employees of the Company and its affiliated companies.

                 (g)      Office and Support Staff.  The Employee shall be
         entitled to an office or offices of a size and with furnishings and
         other appointments, and to secretarial and other


                                     -6-



<PAGE>   7

         assistance, commensurate with those provided to other peer executive
         officers of the Company and its affiliated companies.
        
                 (h)      Vacation.  The Employee shall be entitled to paid
         vacation in accordance with the most favorable agreements, plans,
         policies, programs and practices of the Company and its affiliated
         companies as in effect for the Employee at any time during the 120-day
         period immediately preceding the Change of Control or, if more
         favorable to the Employee, as in effect generally at any time
         thereafter with respect to other peer employees of the Company and its
         affiliated companies.

                 (i)      Indemnification.  If in connection with any agreement
         related to a transaction that will result in a Change of Control of
         the Company, an undertaking is made to provide the Board of Directors
         with rights to indemnification from the Company (or from any other
         party to such agreement), the Employee shall, by virtue of this
         Agreement, be entitled to the same rights to indemnification as are
         provided to the Board of Directors pursuant to such agreement.
         Otherwise, the Employee shall be entitled to indemnification rights on
         terms no less favorable to Employee than those available under the
         Certificate of Incorporation, bylaws or resolutions of the Company at
         any time after the Change of Control to other peer employees of the
         Company.  Such indemnification rights shall be with respect to all
         claims, actions, suits or proceedings to which the Employee is or is
         threatened to be made a party that arise out of or are connected to
         his services at any time prior to the termination of his employment,
         without regard to whether such claims, actions, suits or proceedings
         are made, asserted or arise during or after the Employment Term.

                 (j)      Directors and Officers Insurance.  If in connection
         with any agreement related to a transaction that will result in a
         Change of Control of the Company, an undertaking is made to provide
         the Board of Directors of the Company with continued coverage
         following the Change of Control under one or more directors and
         liability insurance policies, then the Employee shall, by virtue of
         this Agreement, be entitled to the same rights to continued coverage
         under such directors and officers liability insurance policies as are
         provided to the Board of Directors.  Otherwise, the Company shall
         agree to cover Employee under any directors and officers liability
         insurance policies as are provided generally at any time after the
         Change of Control to other executive officers of the Company.

         3.3      OBLIGATIONS UPON TERMINATION AFTER A CHANGE OF CONTROL.

                 (a)      Termination by Company for Reasons other than Death,
         Disability or Cause or by Employee for Good Reason.  If, after a
         Change of Control and during the Employment Term, the Company
         terminates the Employee's employment other than for Cause, death or
         Disability, or the Employee terminates employment for Good Reason,

                          (i)     the Company shall pay to the Employee in a
                 lump sum in cash within five business days of the date of
                 termination an amount equal to three times the sum of (i) the
                 amount of Base Salary in effect at the date of termination,
                 plus (ii) the


                                     -7-



<PAGE>   8


                 greater of (x) the average of the annual bonuses paid or to be
                 paid to the Employee with respect to the immediately preceding
                 three fiscal years or (y) the target Bonus for which the
                 Employee is eligible for the 12-month period in which the date
                 of termination occurs, as such target bonus has been
                 established by the Company for such year;

                          (ii)    for a period of thirty-six (36) months
                 following the date of termination of employment (the
                 "Continuation Period"), the Company shall at its expense
                 continue on behalf of the Employee and his dependents and
                 beneficiaries the life insurance, disability, medical, dental
                 and hospitalization benefits provided (x) to the Employee at
                 any time during the 120-day period prior to the Change in
                 Control or at any time thereafter or (y) to other similarly
                 situated executives who continue in the employ of the Company
                 during the Continuation Period. The coverage and benefits
                 (including deductibles and costs) provided in this Section
                 2.3(a)(ii) during the Continuation Period shall be no less
                 favorable to the Employee and his dependents and beneficiaries,
                 than the most favorable of such coverages and benefits during
                 any of the periods referred to in clauses (x) or (y) above.  In
                 addition, if Employee has reached age 52 and has completed
                 seven years of service at the time of a Change of Control,
                 Employee shall automatically become vested in the
                 post-retirement benefits provided under the Tidewater Group
                 Welfare Benefits Plan (the "GWB Plan") and be entitled to
                 receive, following termination of employment with the Company,
                 all benefits that would be payable to Employee under the GWB
                 Plan or any successor plan of the Company or its affiliated
                 companies had the Employee retired from employment with the
                 Company or one of its affiliated companies on the later of the
                 third anniversary of the Change of Control or the Employee's
                 date of retirement (as defined in the GWB Plan) from employment
                 with the Company.  The Company's obligation hereunder with
                 respect to the foregoing benefits shall be limited to the
                 extent that the Employee obtains any such benefits pursuant to
                 a subsequent employer's benefit plans, in which case the
                 Company may reduce the coverage of any benefits it is required
                 to provide the Employee hereunder as long as the aggregate
                 coverages and benefits of the combined benefit plans is no less
                 favorable to the Employee than the coverages and benefits
                 required to be provided hereunder.  The Employee will be
                 eligible for coverage under the Consolidated Omnibus Budget
                 Reconciliation Act at the end of the Continuation Period or
                 earlier cessation of the Company's obligation hereunder.

                          (iii)   the Employee shall immediately become fully
                 (100%) vested in his benefit under each supplemental or excess
                 retirement plan of the Company in which the Employee was a
                 participant, including, but not limited to the Tidewater, Inc.
                 Supplemental Executive Retirement Plan (the "SERP") , the
                 Supplemental Savings Plan and any successor plans;

                          (iv)    the Company shall contribute to the trust
                 established in connection with the SERP and the Supplemental
                 Savings Plan (the "Trust") for the Employee's


                                     -8-


<PAGE>   9


                 account in cash within five business days of the date of
                 termination of employment an amount equal to the then present
                 value of the actuarial equivalent of the additional benefits,
                 if any, to which the Employee would be entitled under the
                 Tidewater, Inc. Pension Plan, the SERP and any other qualified
                 or non-qualified defined benefit plan maintained by the Company
                 and covering the Employee, regardless of the vesting
                 requirements thereof, if the Employee had continued to be
                 employed by the Company until the third anniversary of
                 the Change of Control.

                          (v)     the Company shall contribute to the
                 Supplemental Savings Plan trust for the Employee's account in
                 cash within five business days of the date of termination of
                 employment an amount equal to the amount of employer
                 contributions that would have been made on the Employees's
                 behalf if the Employee had continued to participate in the
                 Company's Savings Plan, the Company's Supplemental Savings
                 Plan and any other qualified or non-qualified defined
                 contribution plan maintained by the Company until the third
                 anniversary of the Change of Control.  Such contribution
                 shall, in the case of a qualified plan, be calculated as if
                 the Employee were fully vested and participating to the
                 maximum extent permitted by such plan and, in the case of a
                 non-qualified plan, be calculated on the same basis as the
                 Employee was participating in such plans and, in all cases be
                 calculated on the basis of the Employee's annual salary rate
                 at the time of the Change of Control.

                          (vi)    to the extent that Employee is not fully
                 vested in his accrued benefits under the Pension Plan, the
                 Savings Plan or any other qualified plan maintained by the
                 Company, at the time of termination of employment, the Company
                 shall contribute to the Trust, within five business days of
                 the date of termination of employment, an amount in cash equal
                 to the unvested but accrued benefits under such plans as of
                 the date of termination of employment.

         Any contributions by the Company to the Trust as provided herein shall
         be distributed at such time as shall be elected by the Employee at the
         time of execution of this Agreement, except that amounts relating to
         services previously provided shall be distributed in accordance with
         the provisions of the plans or the related participant elections to
         which such contributions relate.  The benefits provided in this Section
         3.3(a) shall be without regard to any amendment to any plans made after
         the Change of Control but prior to Employee's date of termination of
         employment, which amendment adversely affects in any manner the
         computation of benefits under such plans.
        
                 (b)      Death.  If, after a Change of Control and during the
         Employment Term, the Employee's status as an employee is terminated by
         reason of the Employee's death, this Agreement shall terminate without
         further obligation to the Employee's legal representatives (other than
         those already accrued to the Employee), other than the obligation to
         make any payments due pursuant to employee benefit plans maintained by
         the Company or its affiliated companies.

                 (c)      Disability.  If, after a Change of Control and during
         the Employment Term, the Employee's status as an employee is
         terminated by reason of Employee's Disability, this Agreement shall
         terminate without further obligation to the Employee (other than those
         already accrued to the Employee), other than the obligation to make
         any payments due pursuant to employee benefit plans maintained by the
         Company or its affiliated companies.

                 (d)      Cause.  If, after a Change of Control and during the
         Employment Term, the Employee's status as an employee is terminated by
         the Company for Cause, this Agreement shall terminate without further
         obligation to the Employee other than for obligations imposed by law
         and obligations imposed pursuant to any employee benefit plan
         maintained by the Company or its affiliated companies.

                 (e)      Voluntary Termination.  If, after a Change of Control
         and during the Employment Term, the Employee voluntarily terminates
         his employment with the Company other than for Good Reason, this
         Agreement shall terminate without further obligation to the Employee
         other than for obligations imposed by law and obligations imposed
         pursuant to any employee benefit plan maintained by the Company or its
         affiliated companies.

         3.4     ACCRUED OBLIGATIONS AND OTHER BENEFITS.  It is the intent of
this Agreement that upon termination of employment for any reason following a
Change of Control the Employee be entitled to receive promptly, and in addition
to any other benefits specifically provided, (a) the Employee's Base Salary
through the date of termination to the extent not theretofore paid, (b) any
accrued vacation pay, to the extent not theretofore paid, and (c) any other
amounts or benefits required to be paid or provided or which the Employee is
entitled to receive under any plan, program, policy practice or agreement of
the Company.

         3.5     STOCK OPTIONS AND RESTRICTED STOCK.  The foregoing benefits
are intended to be in addition to the value of any options to acquire Common
Stock of the Company or restricted stock the exercisability or vesting of which
is accelerated pursuant to the terms of any stock option, incentive or other
similar plan heretofore or hereafter adopted by the Company.

         3.6     CERTAIN ADDITIONAL PAYMENTS. Notwithstanding anything
contained in this Agreement to the contrary, if the Employee would be subject
to an excise tax by virtue of the "excess parachute payment" provisions of
Section 4999 of the Internal Revenue Code of 1986, as amended (or any successor
thereto) with respect to any amounts attributable to any payment or benefit
provided under this Agreement, or any other payment or benefits provided to, or
for the benefit of Employee under any other Company plan or arrangement (the
"Payments"), and if the imposition of such excise tax could be avoided by a
reduction of the benefits payable pursuant to this Agreement, then the payments
due hereunder shall be automatically reduced by such amount as shall be
necessary to eliminate any obligation of the Employee to pay such excise tax,
provided however that if the amount by which any payments or benefits payable
pursuant to this Agreement would have to be reduced to avoid the imposition of
the excise tax would exceed the excise tax that would be payable with respect
to any "excess parachute payments"(as such term is defined in the Code), then
no such reduction of any payments hereunder shall be made.

         3.7     LEGAL FEES.  The Company agrees to pay as incurred, to the
full extent permitted by law, all legal fees and expenses which the Employee
may reasonably incur as a result of any contest (regardless of the outcome
thereof) by the Company, the Employee or others of the validity or
enforceability of, or liability under, any provision of this Agreement
(including as a result of any contest by the Employee about the amount or
timing of any payment pursuant to this Agreement.)

         3.8     SET-OFF; MITIGATION.  After a Change of Control, the Company's
and its Affiliates' obligations to make the payments provided for in this
Agreement and otherwise to perform its obligations hereunder shall not be
affected by any set-off, counterclaim, recoupment, defense or other claim,
right or action which the Company or its Affiliates may have against the
Employee or others; except that to the extent the Employee accepts other
employment in connection with which he is provided health insurance benefits,
the Company shall only be required to provide health insurance benefits to the
extent the benefits provided by the Employee's employer are less favorable than
the benefits to which he would otherwise be entitled hereunder.  It is the
intent of this Agreement that in no event shall the Employee be obligated to
seek other employment or take any other action by way of mitigation of the
amounts payable to the Employee under any of the provisions of this Agreement.

         3.9     OUTPLACEMENT ASSISTANCE.  Upon any termination of employment
of the Employee other than for Cause within two years following a Change of
Control, the Company shall provide to the Employee outplacement assistance by a
reputable firm specializing in such services for the period beginning with the
termination of employment and ending three years following the Change of
Control.

                               SUMMARY PROVISIONS
                                     OF THE
                                 TIDEWATER INC.
                          ANNUAL INCENTIVE PLAN (AIP)



I.       PLAN OBJECTIVE

         The primary objective of the Tidewater Annual Incentive Plan (AIP) is
         to assist in achieving specific business and financial goals conducive
         to the organization's success which the company believes can best be
         accomplished be providing cash incentives to key Tidewater employees.

         The AIP helps prioritize and focus efforts on the accomplishment of
         financial goals and other corporate objectives established each year
         through the annual planning and budgeting process. This is achieved by
         linking a significant annual element of variable annual compensation
         to the accomplishment of selected goals.  At target performance
         levels, the AIP provides incentive compensation opportunities which,
         in combination with base salary, will yield competitive total
         compensation levels.

II.      BASIC PLAN CONCEPT

         The plan concept focuses primarily on the performance of Tidewater
         overall. The AIP is comprised of three divisions which will enabled
         the company to better measure performance results of eligible
         participants by specific lines of business.  The three divisions are
         as follows:

         o       Administrative
         o       Marine
         o       Compression

         Overall corporate performance is considered each year along with
         certain divisional and individual performance measures specific to
         each division's operations and functions.  Regardless of corporate
         performance, however, the Compensation Committee of the Board may at
         its discretion establish a funding pool of up to 50% of the target
         awards for all participants in order to make awards for outstanding
         individual contributions even if the company does not achieve
         threshold performance on plan performance measures within a year.

III.     ELIGIBILITY CRITERIA

         Eligibility for participation in the AIP will be limited to officers
         and certain key employees that directly impact the company's financial
         performance.  The specific positions eligible to participate in the
         plan will be reviewed and determined annually by Tidewater's Chief
         Executive Officer and the Compensation Committee of the Board of
         Directors.

IV.      AWARD OPPORTUNITIES

         Prior to the beginning of each fiscal year, Tidewater will specify
         target incentive awards for each eligible position.  Prior to the
         beginning of each fiscal year, Tidewater will determine the total pool
         target, threshold and maximum incentive award amounts.  These amounts
         are determined from each eligible participant's base salary times the
         target percent associated with the participant's position within the
         company.  The actual target percent is determined based upon the
         employee's relevant position within the company and the measurable
         amount of direct influence on the company's financial performance.
         For fiscal 1997, the Company has established a base target percent and
         an enhanced target percent that is intended to recognize the
         risk/reward component of the company's overall compensation program.
         Base target and enhanced target percents by position are as follows:

V.       PERFORMANCE MEASURES AND STANDARDS

         Prior to the start of each fiscal year, specific corporate and
         divisional measures and standards will be established.  In addition,
         the appropriate weighing to each measurement will also be established.



                                      2


<PAGE>   5





         A.      Except as provided in Section II of this AIP, before any
                 individual incentive amount can be awarded, the company must
                 first achieve minimum (threshold) performance in at least one
                 of two company performance measures.  For fiscal year 1997,
                 company performance measures are:

                 1.       Adjusted Net Income vs. Budget - Under this test, net
                          income as compared with budgeted net income, adjusted
                          for selected charges/credits of an unusual nature
                          which would not be subject to normal budgeting
                          procedures, is used.  The net income test is a
                          measurement test comparing actual results against
                          budgeted results for the year.  For Fiscal 1997,
                          unless the Company's adjusted net income reaches at
                          least 115% of budget, the participant's base target
                          percentage will be used to determine the total pool
                          amount (see Exhibit 2).  In the event the Company's
                          adjusted net income reaches or exceeds 115% of
                          budget, an enhanced target percent is triggered (see
                          Exhibit 2-A). The enhanced target percent, when
                          triggered, increases the participant's eligible award
                          from the base target percent and applies to all
                          performance measurements.  When determining net
                          income against budget, pro-rating is not permitted
                          between 100% and 115% of budget.

                          In order to have the incentive pay program not
                          inhibit good management/business decisions, certain
                          adjustments to net income should be made in
                          determining if the net income test has been met.
                          Such adjustments should be objectively determinable
                          to avoid the appearance of impropriety.  Accordingly,
                          the following items as reported in the corporation's
                          consolidated statement of earnings should be added to
                          or subtracted from net income as reported in order to
                          determine net income for purposes of the incentive

                                  Discontinued operations; and
                                  Unusual or infrequently occurring items (less
                                  the amount of related income taxes), as that

                          NOTE:  For purposes of calculating achievement of
                          this performance measure, budgeted net income shall
                          be divided by the average number of common shares
                          outstanding for the year as contemplated by the
                          budget.  Likewise, the amount of Adjusted Net Income
                          shall be divided by the average number of common
                          shares outstanding during the year.  For purposes of
                          making both of these Earnings Per Share calculations,
                          common stock equivalents shall not be considered in
                          determining the average number of common shares
                          outstanding.

                 2.       Return of Total Capital (ROTC) - Under this
                          performance measurement, the company must attain at
                          least the 40th percentile when compared to the Value
                          Line Peer Group (see Exhibit 1) on Return of Total
                          Capital (ROTC).  ROTC would be defined as:

                            Earnings Before Interest Expense, Taxes
                            Depreciation and Amortization (EBITDA) 
                            ----------------------------------------------------
                            Average Shareholders Equity + Average Long-Term Debt
                            (including current maturities of Long-Term Debt)

                          NOTE:  Average shareholders' equity and average
                          long-term debt shall be determined by summing the
                          respective totals as of the end of each interim
                          quarterly reporting period during the fiscal year as
                          shown on the company's consolidated balance sheet and
                          dividing such sums by the number of interim reporting
                          periods.

                          The standard for the ROTC performance measure will be
                          established by considering Tidewater's performance
                          against the Value Line Peer Group of companies (see
                          Exhibit 2 - Awards Matrix).  When determining peer
                          group performance ranking, pro-rating is not
                          permitted below the 50th percentile.

         B.      Each participant, within each division, will have specific
                 standards established for the accomplishment of certain
                 company and individual performance measures.  These criteria
                 will be established annually, prior to the beginning of each
                 fiscal year, and will be used to determine the amount of the
                 incentive award that each participant will be eligible to
                 receive.  For Fiscal Year 1997, the performance measures are
                 as follows:

                 1.       Administrative

                          a.      Return on Total Capital - As defined above,
                                  this measurement will carry a weight of 25%
                                  of the individual's total award.

                          b.      Adjusted Net Income - As defined above, this
                                  measurement will carry a weight of 25% of the
                                  individual's total award.

                          c.      Individual Performance - This measurement is
                                  determined on a subjective basis and will
                                  carry a weight of 25% of the individual's
                                  total award.

                          d.      Safety Performance - This measurement is
                                  determined by achievement of the company's
                                  overall established safety performance goals
                                  for the fiscal year.  The safety performance
                                  measurement will carry a weight of 25% of the
                                  individual's total award.

                 2.       Marine

                          a.      Safety Measurement - This measurement will be
                                  considered in three parts.

                                  1.       First, each area will be given a
                                           specific goal to achieve during the
                                           fiscal year with respect to safety
                                           performance as it relates to Lost
                                           Time Accidents. Each area will be
                                           graded on how well it performs
                                           toward achieving the assigned goals.
                                           Attached as Exhibit 3, is the Safety
                                           Lost Time Accident goals for Fiscal
                                           1997.

                                  2.       The second component of this
                                           measurement is related to property
                                           damage.  For fiscal 1997, property
                                           damage performance will be measured
                                           by applying a subjective review of
                                           overall property damage results for
                                           the fiscal year.  Only property
                                           damage above the $20,000 per
                                           occurrence deductible will be
                                           included for measurement purposes.
                                           Property damage claims will be
                                           adjusted to include only Hull
                                           (excluding machinery), Marine
                                           Liability and Pollution claims.  In
                                           other words, preventable property
                                           damage claims.  Exhibit 4, provides
                                           claim details by area for fiscal
                                           1995 and fiscal 1996.  This type of
                                           information will form the basic
                                           parameters that will be reviewed and
                                           considered for fiscal 1997 results.

                                  NOTE:  Within this weighing (1 & 2 above),
                                  personnel safety will comprise 80% and
                                  property damage 20%.

                                  3.       Third, each area is evaluated on its
                                           own overall safety performance,
                                           taking into consideration such
                                           things as number of deaths and/or
                                           disabilities within an area,
                                           incident ratios, nature of
                                           accidents, preventable accidents,
                                           etc.

                                  Notwithstanding the above, no allocation
                                  under this measurement is provided unless the
                                  company achieves its overall established
                                  safety performance goals for the fiscal year.
                                  The safety measurement will carry a weight of
                                  33.33% of the individual's total award.

                                  (NOTE: HOW WELL EACH AREA DEMONSTRATES ITS
                                  COMMITMENT TO TIDEWATER'S SAFETY PROGRAM
                                  OVERALL WILL BE PART OF THE INDIVIDUAL
                                  PERFORMANCE MEASUREMENT.)

                          b.      Margins Test - Under the margins test,
                                  operating margins, as defined, as compared
                                  with a budgeted margins goal, will be used to
                                  determine a component of the incentive pay
                                  pool.  The margins

                                  test will be an area specific test and carry
                                  a Weight of 33.33% of the individual's total
                                  award.  Operating margins for this purpose
                                  will be defined as follows:

                          c.      Individual Performance - Individual
                                  performance is determined annually and is
                                  based upon a subjective evaluation by the
                                  participant's manager(s) and encompasses the
                                  overall performance of the individual for the
                                  fiscal year.  Individual performance will
                                  also include an evaluation of each area's
                                  commitment to Tidewater's safety program
                                  overall.  This measurement will carry a
                                  weight of 33.34% of the individual's total
                                  award.

                                  Included as part of the individual
                                  performance measure may be an area specific
                                  test.  This test may be optional by area and
                                  would consist of zero to two specific
                                  criteria relevant to a given area.  Each
                                  specific area will be advised of any specific
                                  test for that fiscal year.  Some examples
                                  would be the percent improvement in
                                  receivables over a period of time, delinquent
                                  receivables collected, revenue enhancement
                                  achieved over a period of time, utilization,
                                  or other such criteria as deemed appropriate.
                                  When an area specific test is utilized, the
                                  particular measurement will be weighted as
                                  part of the individual performance weight.

                                  Tidewater Compression and TideAir & Gas, will
                                  be reviewed independently of one another.
                                  Therefore, it is possible for one segment's
                                  participants to receive awards for meeting
                                  this criterion and not the other if one
                                  segment does not reach its performance
                                  criteria. However, the overall corporate
                                  performance measures must be positive before
                                  consideration of any incentive awards. Under
                                  the margins test, segment operating margins,
                                  as defined, as compared with a budgeted
                                  margins goal, will be used to determine a
                                  component of the incentive pay pool.  The
                                  margins test will carry a weight of 60% of
                                  the individual's total award. Segment
                                  operating margins for this purpose will be
                                  defined as follows:

                                  Segment Revenues from all operating
                                  activities as reported in the corporation's

                                              and amortization expense, as
                                              reported in the corporation's
                                              consolidated income statement

                                              subsidiaries of the division.
                                              
                                  Equals      Segment Operating Margins, 
                                              as defined.

                          b.      Individual Performance - Individual
                                  performance is determined annually and is
                                  based upon a subjective evaluation by the
                                  participant's manager(s) and encompasses the
                                  overall performance of the individual for the
                                  fiscal year.  This measurement will carry a
                                  weight of 40% of the individual's total
                                  award.

                                  Included as part of the individual
                                  performance measure may be an area specific
                                  test.  This test may be optional by area and
                                  would consist of zero to two specific
                                  criteria relevant to a given area.  Some
                                  examples would be the percent improvement in
                                  receivables over a period of time, delinquent
                                  receivables collected, revenue enhancement
                                  achieved over a period of time,

                                  utilization, or other such criteria as deemed
                                  appropriate.  When an area specific test is
                                  utilized, the particular measurement will be
                                  weighted as part of the individual performance
                                  weight.

VI.      AWARD CALCULATIONS

         A.      Development of Incentive Funding Pool

                 The actual amount of the incentive pool to be awarded depends
                 on the attainment of specified corporate performance measures
                 as set forth in Section V-A.  Each corporate measurement will
                 operate independently of one another in creating the funding
                 pool for annual incentive awards.  Thus the company could
                 achieve above threshold on one performance measure and below
                 threshold on another performance measure and still have funds
                 available in the annual incentive pool.

                 Exhibit 2, attached, provides a matrix example of how the size
                 of the incentive funding pool would be calculated at different
                 levels of corporate performance.  The Matrix also shows:

                 o        The percentage of aggregate target annual incentives
                          paid for all plan participants; and

                 o        The total amount of money allocated to the incentive
                          funding pool for fiscal 1997.

         B.      Individual Awards

                 The incentive funding pool is allocated to individual plan
                 participants by the performance measures set forth in Section
                 V-B.

                 Each division will also be looked at independently of one
                 another; therefore, it is possible for the Marine Division to
                 receive individual awards for meeting performance criteria and
                 not the Compression Division if it does not reach its
                 performance criteria.  However, the overall corporate
                 performance measures must be positive before consideration of
                 any incentive awards.

                 The size of each divisional incentive pool is based upon the
                 number of eligible participants in each division.  For
                 example, if the company meets target goals, each participant's
                 annual base salary is multiplied by the participants target
                 percent amount.  All target amounts are then added together to
                 produce the total pool for that division.  Each divisional
                 pool would be adjusted based upon the actual results of the
                 overall corporate measurements.

VII.     AWARD PAYMENTS

         It is anticipated that awards will be payable in cash; however, the
         company reserves the right to make payment in the form of company
         stock at the company's option.  Awards will be paid as soon as
         administratively possible after the close of the fiscal year.

VIII.    TRANSFERS

         In the event that a participant transfers from one position to another
         during the course of the year, his/her award for the year will be
         calculated on a pro-rata basis according to the proportion of time
         spent in each position during the year.

IX.      RETIREMENTS AND TERMINATIONS

         To receive an award under the AIP, the participant must be actively
         employed on the last day of the performance cycle.  At the discretion
         of the Chief Executive Officer and with the approval of the
         Compensation Committee of the Board of Directors, a participant who
         separates from service prior to the end of the performance cycle may
         be granted an award.  The amount of the award, if any, will be based
         in part upon the length of time employed during the performance cycle.

X.       PLAN ADMINISTRATION, MODIFICATION, AND ADJUSTMENT

         The AIP will be administered by Tidewater's Chief Executive Officer,
         who may delegate certain elements of program administration to the
         Chief Financial Officer and the Director of Employee Relations.
         Actual performance goals, standards, and award determinations will be
         approved by the Compensation Committee of the Board of Directors.

                   (ii) it shall be liable for, and shall indemnify and hold

                   of any injury or damage to any person and any damage to or
                   loss of any property of any person whatsoever in connection
                   with its inspection of the Vessels; and (iii) inspection of
                   any particular Vessel shall be subject to the Vendor or the
                   relevant member of the Sale Group having obtained the prior
                   consent of the charterer of such Vessel to such inspection
                   (and the Vendor agrees to use and to procure that each
                   relevant member of the Sale Group uses, all reasonable
                   endeavours, (excluding the expenditure of money) to obtain
                   such consent).

        (C)        In addition and without limiting sub-clause (A), the Vendor
                   undertakes to and agrees with the Purchaser that the

                   general meeting of the shareholders of the Vendor (the
                   "Extraordinary General Meeting") to be held on or prior to
                   21st April 1997 for purposes of considering and, if thought
                   fit, passing the resolution referred to in paragraph (A)(1)
                   of Schedule 2 (the "Resolution") (ii) procure the posting of
                   a circular to shareholders as soon as reasonably practicable
                   after, but, in any event, within 14  days of the date of
                   execution of this Agreement containing, subject to their
                   fiduciary duties as directors, a recommendation from the
                   Board of the Vendor that its shareholders vote at the
                   Extraordinary General Meeting in favour of the Resolution
                   and, in any event, a statement that each of the members of
                   the Board intends to vote his shares in favour of the
                   Resolution; and (iii) subject, in each case,

                   or further resolution or recommendation inconsistent with

                   recommendation to the shareholders prior to the
                   Extraordinary General Meeting.

        (D)        If a Competing Acquisition Proposal is publicly announced
                   prior to the earlier of Completion and the termination of
                   this Agreement and either, (i) the directors of the Vendor
                   withdraw their favourable recommendation to the shareholders
                   or make any other or further resolution or recommendation
                   inconsistent with such favourable recommendation or (ii) the
                   shareholders of the Vendor fail to approve the sale of the
                   Sale Shares at the Extraordinary General Meeting then the

                   of the obligations of the Vendor under this Agreement and to
                   the exclusion of any other remedy or right which the

                              Vessels that the Purchaser has concluded would be
                              necessary for such Vessels to be in Satisfactory
                              Condition (as defined in that paragraph), it
                              being understood that any such information

                              to this sub-clause shall not preclude the

                              expenditures or asserting that other bases exist
                              for claiming that such Completion Condition has
                              not been satisfied in the event of a dispute
                              between the parties.

6.2     LIAISON ON CONDUCT OF BUSINESS

        The Vendor covenants that, from the date of this Agreement until
        Completion, the business of the Sale Group will be carried on in the
        usual and normal course and that no member of the Sale Group shall
        enter into any contract or commitment or do anything which, in any such

                   or (iii) for a term in excess of six months, or (iv) having
                   change of control or other comparable provisions that would
                   cause such contracts to terminate on, or cause by its terms
                   the rights or obligations of the parties thereto to be
                   materially affected by, the sale of the Sale Shares to the

                   other than those made in the ordinary course of business and
                   consistent with past practices out of available cash
                   (excluding the proceeds of borrowings) (it being understood
                   that any capital expenditures made or agreed to be made with
                   respect to the acquisition of a vessel shall be deemed
                   outside of the ordinary course of business); or

        (E)        save as referred to in the Disclosure Letter, shall not
                   declare, make or pay any dividends or distributions (whether

        (A)        for the period of 3 years after Completion, either on its
                   own account or in conjunction with or on behalf of any
                   person, carry on, or be engaged, concerned or interested
                   (directly or indirectly) in carrying on anywhere in the

                   advertisement or who is approached by or who approaches the
                   Vendor or any of its Affiliates, at a time when he is no
                   longer an employee of any such member or of the Purchaser)
                   whether or not such person would commit a breach of contract
                   by reason of leaving service or transferring business; and

        (C)        directly or indirectly use or attempt to use in the course

                   any trade or service mark or logo used in the business of
                   any member of the Sale Group (including, but not limited to
                   OSA and/or OIL names or marks) or any other name, logo,
                   trade or service mark which is or might be confusingly
                   similar thereto.

<PAGE>   15
7.3     REASONABLENESS

        The restrictions contained in sub-clause 7.2, as qualified by the
        exceptions contained in this clause 7, are considered reasonable by the
        parties, but if any such restriction shall be found to be void or
        voidable but would be valid and effective if some part or parts of the
        restriction were deleted, or the period or area of application reduced,
        such restriction shall apply with such modification as may be necessary
        to make it valid and effective.

7.4     REGISTRATION

        Any provision of this Agreement, or of any agreement or arrangement of
        which it forms a part, by virtue of which such agreement or arrangement
        is subject to registration under the Restrictive Trade Practices Act
        1976 shall only take effect the day after particulars of such agreement
        or arrangement have been duly furnished to the Director General of Fair
        Trading pursuant to section 24 of that Act.

7.5     LIMITED EXCEPTIONS

        (A)        Nothing contained in sub-clause 7.2 shall prohibit the
                   Vendor or any Affiliate of the Vendor from making
                   acquisitions of other businesses an insignificant part of
                   which consists of activities that would but for this clause
                   7.5 constitute a breach by the Vendor, or any Affiliate of
                   the Vendor, of the restrictions contained in sub-clause 7.2,
                   provided that the Vendor or such Affiliate disposes of any
                   business or assets that would otherwise be in breach of
                   sub-clause 7.2 within one year of the date of acquisition.
                   For the purposes of the foregoing an "insignificant" part
                   means less than 20% by reference to the contribution to
                   total revenues of the business so acquired.

        (B)        Nothing contained in clause 7.2 shall prohibit O.I.L.
                   (Shetland) Limited from continuing to carry on its existing
                   business in the same scope and manner and to the same extent
                   as presently carried on.

        (C)        Nothing contained in sub-clause 7.2(C) shall prohibit O.I.L.
                   (Shetland) Limited using "O.I.L." as part of its name for a
                   period of twelve months from Completion.

        (D)        The Purchaser covenants that neither it nor any member of
                   the Sale Group shall following the expiry of twelve months
                   after Completion use the name or business name "Ocean" or
                   the logo used by the Vendor in its business or any other
                   name, logo, trade or service mark which is or might be
                   confusingly similar thereto.

8. WARRANTIES

8.1     PURCHASER'S KNOWLEDGE

        The Warranties are given subject to matters fairly disclosed in this
        Agreement or in the Disclosure Letter, but no other information
        relating to the Sale Group of which the Purchaser has knowledge (actual
        or constructive) shall prejudice any claim made by the Purchaser under
        the Warranties or operate to reduce any amount recoverable.

8.2     WARRANTIES TO BE INDEPENDENT

        Each of the Warranties shall be separate and independent and, save as
        expressly provided, shall not be limited by reference to any other
        Warranty or anything in this Agreement.

8.3     FURTHER DISCLOSURE

        Each of the parties shall prior to Completion forthwith disclose in
        writing to the other any act, action, event or occurrence which may
        arise or become known to it after the date of this Agreement and before
        Completion which constitutes a material breach of the Warranties or
        which would constitute a breach with respect to the Warranties if they
        were to be repeated as at Completion.

8.4     RIGHT OF TERMINATION

        In the event of:-

        (A)        it becoming apparent on or before Completion that the Vendor
                   is in breach of any of the Warranties to an extent which
                   constitutes, individually or collectively, a Material
                   Breach; or

        (B)        any act, action, event or occurrence arising after the date
                   of this Agreement and before Completion which would if the
                   Warranties were to be repeated as at Completion, constitute
                   a Material Breach of the Warranties; or

        (C)        the failure by the Vendor to perform and comply in all
                   material respects with all agreements and covenants required
                   to be performed or complied with by it prior to or on the
                   Completion Date, including without limitation, the
                   provisions regarding Liaison of Business in clause 6.2;

        then, in any such event, the Purchaser may terminate this Agreement by
        notice in writing to the Vendor, such termination discharging in full
        all obligations of each party to the other and so that this Agreement
        shall cease to be of any force or effect but without prejudice to the
        provisions of clause 12.2 and (in relation to sub-paragraph 8.4(A)
        only) of clause 4.2(D).


                                      13


<PAGE>   17
        For the purposes of this sub-clause 8.4 (A) and (B) only, a Material
        Breach shall be deemed to have occurred with respect to the Warranties
        if there transpires any act, action, event or occurrence that
        constitutes or that would, if such Warranties were to be given as at
        Completion, have constituted a breach of such Warranties and that
        results, or would reasonably be likely to result, individually or in
        the aggregate, in a quantifiable loss of L.20 million or more.

        For the purposes of sub-clause 8.4(C) only, a failure to perform and
        comply with covenants and obligations in all material respects shall be
        deemed to occur if that results, or would reasonably be likely to
        result, individually or in aggregate, in a quantifiable loss of L.10
        million or more.

9. CONFIDENTIALITY

        The confidentiality obligations of the parties shall continue to be
        governed by the Confidentiality Agreement.

10. ANNOUNCEMENTS

10.1    RESTRICTION

        Between the date hereof and the Completion Date, and subject to
        sub-clause 10.2, neither the Vendor nor the Purchaser shall make any
        announcement concerning the sale of the Sale Shares without the prior
        written approval of the other, such approval not to be unreasonably
        withheld or delayed.

10.2    PERMITTED ANNOUNCEMENTS

        Either the Vendor or the Purchaser may make an announcement concerning
        the sale of the Sale Shares if the announcement is required by law or
        by any securities exchange or regulatory or governmental body having
        jurisdiction over it, wherever situated, including but not limited to
        the United States Securities and Exchange Commission, the New York
        Stock Exchange, the London Stock Exchange, and The Panel on Take-overs
        and Mergers, and whether or not the requirement has the force of law
        provided that any such announcement shall be made only after
        consultation with the other party to the extent that the same is
        practicable.

11. PROVISIONS RELATING TO THIS AGREEMENT

11.1    ASSIGNMENT

        (A)        This Agreement and the benefits and obligations under it and
                   any part of it (including the Warranties) shall not be
                   assignable except that the Purchaser may, upon giving
                   written notice to the Vendor, assign the benefit (but not
                   the burden) of this Agreement to an Affiliate of the
                   Purchaser provided that any such assignee remains an
                   Affiliate of the

                   Purchaser and provided further that before such assignee

        Claim relating to or arising or resulting from or which would not have
        been made but for (i) any Release prior to the date hereof of Hazardous

        The Purchaser shall provide prompt written notice to the Vendor of any
        matter of which the Purchaser shall become aware which gives rise to or

        reason of an Environmental Claim and, as a result, a claim under the
        Environmental Indemnity.

14.4    ENVIRONMENTAL PROCEEDINGS

        (A)        In relation to Environmental Proceedings in the form of
                   third party claims resulting from any matter to which the
                   indemnity in clause 14.1 is applicable, the Vendor (or such
                   other person as the Vendor shall determine) shall have the
                   right at any time to assume conduct of such Environmental
                   Proceedings Provided that such right is subject to the
                   Vendor agreeing at the time of such assumption that any Loss
                   which may be incurred by the Purchaser or any member of the
                   Sale Group shall (subject to the other provisions of this
                   clause 14) be recoverable under the indemnity contained in
                   sub-clause 14.1.

        (B)        If Environmental Proceedings arise under sub-clause 14.4(A)
                   above and the Vendor does not assume conduct of such
                   Environmental Proceedings as provided for in such
                   sub-clause, the Purchaser (or such other person as the
                   Purchaser shall determine) shall have conduct of such
                   Environmental Proceedings.

        (C)        In relation to Environmental Proceedings in the form of an
                   action brought by a regulatory authority resulting from any
                   matter to which sub-clause 14.1 applies, the Purchaser (or
                   such other person as the Purchaser shall determine) shall
                   have the right to assume conduct of such Environmental
                   Proceedings.

        (D)        The person having conduct of any Environmental Proceedings
                   as provided for above (the "Conduct Party") shall ensure
                   that:

                   (1)        reasonably frequent and detailed reports shall be
                              provided to the other party regarding the
                              progress of such Environmental Proceedings;

                              correspondence and documents passing between the
                              parties to such Environmental Proceedings shall
                              be provided to the other party;

                   (3)        all reasonable efforts are made in such
                              Environmental Proceedings to minimise losses;
