TIDEWATER INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS



(1)  Interim Financial Statements

     The consolidated financial information for the interim periods presented
     herein has not been audited by independent accountants, but in the opinion
     of management, all adjustments (consisting only of normal recurring
     adjustments) necessary for a fair presentation of the condensed
     consolidated balance sheets and the condensed consolidated statements of
     earnings and cash flows at the dates and for the periods indicated have
     been made.  Results of operations for interim periods are not necessarily
     indicative of results of operations for the respective full years.

(2)  Earnings per Share Data

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

(3)  Income Taxes

     Income tax expense for interim periods is based on estimates of the
     effective tax rate for the entire fiscal year.  The effective tax rate was
     32% for the quarter and six-month period ended September 30, 1996.  For
     the quarter and six-month period ended September 30, 1995 the effective
     tax rate was 33%.

     The Internal Revenue Service has notified the company of proposed
     deficiencies resulting from the audit of the company's 1992 and 1993 tax
     returns.  The company is in the process of preparing its defenses against
     these claims, and in management's opinion the ultimate outcome of these
     matters will not have a materially adverse effect on the company's
     financial position and results of operations.

 (4) Acquisition of Marine Joint-Venture

     During fiscal 1997's first quarter the company acquired 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 as a purchase 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.

INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders of Tidewater Inc.:

We have reviewed the condensed consolidated balance sheet of Tidewater Inc. and
subsidiaries as of September 30, 1996 and the related condensed consolidated
statements of earnings and cash flows for the three-month and six-month periods
ended September 30, 1996 and 1995.  These financial statements are the
responsibility of the Company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters.  It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, the objective of
which is the expression of an opinion regarding the financial statements taken
as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the condensed consolidated financial statements referred to above
for them to be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Tidewater Inc. as of March 31,
1996, and the related consolidated statements of earnings, stockholders'
equity, and cash flows for the year then ended (not presented herein); and in
our report dated April 29, 1996 we expressed an unqualified opinion on those
consolidated financial statements.  In our opinion the information set forth in
the accompanying condensed consolidated balance sheet as of March 31, 1996 is
fairly presented, in all material respects, in relation to the consolidated
balance sheet from which it has been derived.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS


The company provides services and equipment to the international 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 natural gas compression rental fleet.  Activity
levels for the marine vessel fleet and the natural gas 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.  The
following discussion should be read in conjunction with the unaudited condensed
consolidated financial statements and related disclosures.

MARINE DIVISION

The Marine division provides a diverse range of services and equipment to the
offshore oil and gas industry.  Fleet size, utilization and vessel day rates
primarily determine the amount of revenues and operating profit because
operating costs and depreciation do not change proportionally with changes in
revenues.  Operating costs consist primarily of crew costs, repair and
maintenance, insurance, fuel, lube 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
expense and depreciation expense) and operating margins of the Marine
division's owned and operated vessel fleet for the quarters and six-month
periods ended September 30 and for the quarter ended June 30, 1996:

</TABLE>

Fiscal 1997 second quarter and six-month operating margins climbed above fiscal
1996's respective amounts due to the beneficial effects of higher utilization
and average day rates for the worldwide fleet and a larger North Sea fleet
outweighing the adverse effect of higher operating expenses.  Current quarter
operating margins also climbed above the prior quarter amount due to higher
utilization and average day rates for the domestic-based fleet and a full
quarter's results





                                       7

for the North Sea fleet being partially offset by higher operating expenses.
Greater demand and a much more favorable supply/demand relationship for
offshore marine services in the U.S. Gulf of Mexico were primarily responsible
for the increases in utilization and average day rates for the current quarter
and six-month period compared with the respective fiscal 1996 periods, and for
the current quarter compared with the prior quarter.  A larger North Sea fleet
is due to fiscal 1997's first quarter acquisition of several safety/standby
vessels.  Higher operating expenses for the current quarter and six-month
period compared with fiscal 1996's respective periods and for the current
quarter compared with the preceding quarter resulted primarily from increased
activity for the domestic-based fleet, the expansion of the North Sea fleet and
increased costs associated with retaining qualified vessel personnel and
attracting and training new vessel personnel.  Higher operating expenses for
the quarter and six-month period ended September 30, 1996 compared with the
quarter and six-month period ended September 30, 1995 were also due to higher
repair and maintenance costs resulting from a greater number of vessel
drydockings.

Revenues, operating expenses (excluding general and administrative expense and
depreciation expense) and operating margins of brokered vessels, shipyard and
other activities for the quarters and six-month periods ended September 30 and
for the quarter ended June 30, 1996 were:

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.

Marine vessel day rates are determined by the demand created through the level
of offshore exploration, development and production spending by energy
exploration and production companies relative to the supply of offshore service
vessels.  Suitability of equipment and the degree of service provided also
influence vessel day rates.  The following two tables compare day-

were for additions to and/or modifications of the existing vessel fleet.  In
the prior 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 prior periods these vessels were classified as joint-venture owned.
The average size of the domestic-based fleet fell from September 1995 to
September 1996 due to vessel sales, the return of previously leased vessels to
their owners and the withdrawal of several vessels from active service in
fiscal 1997's first quarter because of age and anticipated higher repair and
maintenance costs.  The following table compares the average number of vessels
by class and geographic distribution for the quarters and six- month periods

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 period-to- period 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





                                       10
<PAGE>   11
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 gas compression operations for the
quarters and six-month periods ended September 30 and for the quarter ended
June 30, 1996.

Compared to the corresponding quarter of fiscal 1996, fiscal 1997 second
quarter and six-month operating margins fell as a result of increased
competition which weakened rental rates and entirely offset the positive effect
of higher utilization.

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 sales margins for equipment and parts
sales for the quarters and six-month periods ended September 30 and for the
quarter ended June 30, 1996:

Fluctuations in the level of equipment and parts sales for the periods
presented are due to the timing of sales of engineered products.  Fluctuations
in gross profit margin percentages are the result of competitive market forces.
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 the
current year-to-date period was $7.2 million and was primarily for
modifications of existing equipment to meet

customer requirements.  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.  Revenues from the rental of air
equipment for the six-month period ended September 30, 1996 were $.7 million.
Gains from sales of assets, excluding air rental equipment, for the current
quarter and six-month period were $.4 million and $.6 million, respectively.
Gains from sales of assets for the corresponding quarter and six-month period
of fiscal 1996 contributed nominally to division operating profits.

CORPORATE

Fiscal 1997 second quarter and six-month financing activities consumed less
cash compared with the respective fiscal 1996 periods due to lower principal
payments on long-term debt.  Principal payments on long-term debt during the
current quarter and six-month periods were primarily for the repayment, prior
to maturity, of outstanding debt assumed in connection with the purchase of the
remaining equity in the joint-venture companies in the North Sea.  Interest
expense in the quarter and six-month periods ended September 30, 1996 was lower
than the corresponding fiscal 1996 periods as a result of the fiscal 1996
fourth quarter prepayments of debt assumed in connection with the fiscal 1996
fourth quarter merger with Hornbeck Offshore Services, Inc.

General and administrative expenses for the quarters and six-month periods
ended September 30 and for the quarter ended June 30, 1996 consist of the
following:

</TABLE>

CURRENCY FLUCTUATIONS AND INFLATION

Because of its significant international operations, the company is exposed to
currency fluctuations and exchange risks.  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 oil and gas industry and the energy services industry will
increase.  Future improvements in vessel day rates and compressor rental rates
may buffer the company from the inflationary effects on operating costs.


ENVIRONMENTAL MATTERS

During the ordinary course of business the company's operations are subject to
a wide variety of environmental laws and regulations.  The company attempts to
comply with these laws and regulations in order to avoid costly accidents and
any related environmental damage.

Item 6.  Exhibits and Reports on Form 8-K

A.  At page 15 of this report is the index for those exhibits required to be
    filed as a part of this report.

B.  The Company filed a Current Report on Form 8-K dated September 19, 1996
    which disclosed its Board of Directors adopted an updated Rights Plan
    designed to supersede a Rights Plan originally adopted April 1990.  As with
    its previously adopted Rights Plan, the new Rights Plan is intended to
    protect stockholder interests in the event the company becomes the subject
    of a takeover initiative that would deny the company's stockholders the
    full value of their investment.  The new Rights, which will be issued to 
    each common stockholder of record on October 1, 1996, will be exercisable
    only if a person acquires, or announces a tender offer which would result
    in ownership of, 15 percent or more of the company's common stock.  The
    board of directors will be authorized in certain circumstances to lower
    this 15 percent threshold to not less than 10 percent. The initial exercise
    price will be $160.00 per Right.  The Rights will expire on November 1,
    2006, unless redeemed or exchanged at an earlier date.

                          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

<PAGE>   3
                          (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
         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.

<PAGE>   4
                 (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, 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





                                      -4-

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 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 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.

                 (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





                                      -6-
<PAGE>   7
         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 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





                                      -7-
<PAGE>   8
                 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 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





                                      -8-
<PAGE>   9
                 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 affiliated companies and any death benefits to
         which the Employee is entitled under any Employment Agreement in
         effect immediately prior to





                                      -9-
<PAGE>   10
         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
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.

being no obligation to give such consent) other than such rights or benefits as
are transferred by will or the laws of descent and distribution.

                 (c)      The Company shall require any successor to or
assignee of (whether direct or indirect, by purchase, merger, consolidation or
otherwise) all or substantially all of the assets or businesses of the Company
(i) to assume unconditionally and expressly this Agreement and (ii) to agree to
perform or to cause to be performed all of the obligations under this Agreement
in the same manner and to the same extent as would have been required of the
Company had no assignment or 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
Company or any such successor or assignee to agree to cause to be performed all
of the obligations under this Agreement, such agreement to be set forth in a
writing reasonably satisfactory to the Employee.

                          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) and
              paragraphs (ii) and (iii), shall include a corporation which as a
              result of such transaction controls the Company





                                      -2-
<PAGE>   3
              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 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





                                      -3-
<PAGE>   4
       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 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





                                      -4-
<PAGE>   5
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 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 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
              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





                                      -7-
<PAGE>   8
              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 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





                                      -8-
<PAGE>   9
              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





                                      -9-
<PAGE>   10
       (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.

<PAGE>   11
       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.

be assignable by the Employee without the consent of the Company (there being

transferred by will or the laws of descent and distribution.

              (c)    The Company shall require any successor to or assignee of
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
all or substantially all of the assets or businesses of the Company (i) to
assume unconditionally and expressly this Agreement and (ii) to agree to
perform or to cause to be performed all of the obligations under this Agreement
in the same manner and to the same extent as would have been required of the
Company had no assignment or succession occurred, such assumption to be set
forth in a writing reasonably satisfactory to the Employee.

                          CHANGE OF CONTROL AGREEMENT


       This Change of Control Agreement ("the Agreement") between Tidewater,
Inc., a Delaware corporation (the "Company"), and Joseph S. Bennett (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





                                      -2-

              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 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





                                      -3-
<PAGE>   4
       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

       This Agreement supersedes the agreement dated June 25, 1992 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, 1996; provided, however, that commencing on January 1, 1997 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, 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





                                      -4-
<PAGE>   5
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 an equivalent position in the
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 other peer employees,
       and, to the extent that salary increases are granted to such other peer
       employees, the Employee shall be granted a salary increase commensurate
       with his peer employees 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 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 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.

<PAGE>   6
              (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 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 assistance, commensurate with
       those provided to other peer employees of the Company and its affiliated
       companies.
        




                                      -6-
<PAGE>   7
              (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 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 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, then, subject to Section
       3.6 hereof,

                     (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 two times the sum 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





                                      -7-
<PAGE>   8
              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 twenty-four (24) 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 53 and has completed eight 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 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





                                      -8-
<PAGE>   9
              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 second 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 second anniversary of the Change of Control.  Such
              contribution shall, in the case of a qualified plan, be
              calculated as if the Employee were 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





                                      -9-
<PAGE>   10
       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    LIMITATION ON PAYMENTS.  Notwithstanding anything contained in
this Agreement to the contrary, to the extent that any payment or benefit
provided under this Agreement and benefits provided to, or for the benefit of,
the Employee under any other Company plan or arrangement or any agreement with
the Company, [any person whose actions result in a change in control of the
Company] or any person affiliated with the Company or such person (such
payments or benefits are collectively referred to as the "Payments") would not
be deductible (in whole or in part) as a result of Section 280G of the Internal
Revenue Code of 1986, as amended (the "Code"), the Payments shall be reduced
(but not below zero) until no portion of the Payments is not deductible by the
Company as a result of Section 280G of the Code (such reduced amount is
hereinafter referred to as the "Limited Payment Amount").  Unless the Employee
shall have given prior written notice specifying a different order to the
Company to effectuate the Limited Payment Amount, the Company shall reduce or
eliminate the Payments, by first reducing or eliminating those payments or
benefits that are not payable in cash and then by reducing or eliminating cash
payments, in each case in reverse order





                                      -10-
<PAGE>   11
beginning with payments or benefits which are to be paid the farthest in time
from the Determination (as hereinafter defined).  Any notice given by the
Employee pursuant to the preceding sentence shall take precedence over the
provisions of any other plan, arrangement or agreement governing the Employee's
rights and entitlements to any benefits or compensation.  A determination as to
whether the Payments shall be reduced to the Limited Payment Amount pursuant to
the Plan and the amount of such Limited Payment Amount shall be made by the
Company's auditors that served as the Company's independent auditors 120 days
preceding the Change of Control (the "Auditors") at the Company's expense.  The
Auditors shall provide their determination (the "Determination"), together with
detailed supporting calculations and documentation to the Company and the
Employee.

       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.

                                 MISCELLANEOUS

       4.1    BINDING EFFECT; SUCCESSORS.

benefit of the Company and any of its successors or assigns.

              (b)    This Agreement is personal to the Employee and shall not

no obligation to give such





                                      -11-
<PAGE>   12
consent) other than such rights or benefits as are transferred by will or the
laws of descent and distribution.

              (c)    The Company shall require any successor to or assignee of
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
all or substantially all of the assets or businesses of the Company (i) to
assume unconditionally and expressly this Agreement and (ii) to agree to
perform or to cause to be performed all of the obligations under this Agreement
in the same manner and to the same extent as would have been required of the
Company had no assignment or succession occurred, such assumption to be set
forth in a writing reasonably satisfactory to the Employee.

              (d)    The Company shall also require all entities that control
or that after the transaction will control (directly or indirectly) the Company
or any such successor or assignee to agree to cause to be performed all of the
obligations under this Agreement, such agreement to be set forth in a writing
reasonably satisfactory to the Employee.

extent be invalid, illegal or unenforceable in any respect as written, Employee
and the Company intend for any court construing this Agreement to modify or
limit such provision so as to render it valid and enforceable to the fullest
extent allowed by law.  Any such provision that is not susceptible of such
reformation shall be ignored so as to not affect any other term or provision
hereof, and the remainder of this Agreement, or the application of such term or
provision to persons or circumstances other than those as to which it is held
invalid, illegal or unenforceable, shall not be affected thereby and each term
and provision of this Agreement shall be valid and enforced to the fullest
extent permitted by law.

       4.7    WAIVER OF BREACH.  The waiver by either party of a breach of any
provision of this Agreement shall not operate or be construed as a waiver of
any subsequent breach thereof.

       4.8    REMEDIES NOT EXCLUSIVE.  No remedy specified herein shall be
deemed to be such party's exclusive remedy, and accordingly, in addition to all
of the rights and remedies provided for in this Agreement, the parties shall

regulation.
