To our Stockholders:
   
     You are cordially invited to attend a Special Meeting of Stockholders of
Hornbeck Offshore Services, Inc. ("Hornbeck") to be held at the Hotel Galvez,
2024 Seawall Boulevard, Galveston, Texas, on Wednesday, March 13, 1996, at
11:00 a.m. Galveston time.
    
     At the meeting, you will be asked to adopt an Agreement and Plan of
Merger (the "Merger Agreement") pursuant to which Hornbeck would be acquired
by Tidewater Inc. ("Tidewater"). The terms of the Merger Agreement provide
that, upon consummation of the merger, each issued and outstanding share of
Hornbeck common stock would be converted into the right to receive .667 of a
share of Tidewater common stock (subject to adjustment as described in the
enclosed Proxy Statement/Prospectus) and Hornbeck would become a wholly owned
subsidiary of Tidewater. In addition, Larry D. Hornbeck, currently Chairman of
the Board, President and Chief Executive Officer of Hornbeck, would become a
Tidewater director.

     The attached Notice of Special Meeting and Proxy Statement/Prospectus
contains a description of the formal business to be conducted at the meeting.
During the meeting, Hornbeck management will also report on Hornbeck
operations and the proposed merger and, along with Tidewater representatives,
will be available to respond to questions.

     YOUR BOARD OF DIRECTORS BELIEVES THAT THE MERGER AGREEMENT, WHICH WAS
APPROVED UNANIMOUSLY BY THE BOARD, IS IN THE BEST INTERESTS OF HORNBECK AND
ITS STOCKHOLDERS AND RECOMMENDS THAT YOU VOTE FOR THE ADOPTION OF THE MERGER
AGREEMENT.

     You are urged to read carefully the Proxy Statement/Prospectus in its
entirety for a complete description of the proposed merger. Please sign, date
and return the enclosed proxy card promptly. It is important to vote. If you
fail to return your proxy card, the effect of such failure will be as if you
voted your shares against adoption of the Merger Agreement. If you attend the
meeting, which we hope that you will, you may vote in person even if you have
previously mailed a proxy card. We look forward to meeting with you at the
Special Meeting of Stockholders.

                                          Sincerely,
                                          LARRY D. HORNBECK

and Plan of Merger (the "Merger Agreement") among Hornbeck, on the one hand, and
Tidewater Inc. ("Tidewater") and Tidewater Expansion, Inc., a wholly owned
subsidiary of Tidewater ("Newco"), on the other hand, a copy of which is
attached as Appendix A to the Proxy Statement/Prospectus, pursuant to which,
among other things (a) Newco would merge with and into Hornbeck, (b) Hornbeck
would become a wholly owned subsidiary of Tidewater, and (c) each issued and
outstanding share of common stock of Hornbeck would be converted into the right
to receive .667 of a share of Tidewater common stock, subject to adjustment as
described in the enclosed Proxy Statement/Prospectus.

THE SPECIAL MEETING
   
     A special meeting of Hornbeck Offshore Services, Inc., a Delaware
corporation ("Hornbeck"), will be held on Wednesday, March 13, 1996, at 11:00
a.m. local time at the Hotel Galvez, 2024 Seawall Boulevard, Galveston, Texas
(the "Special Meeting"). Only holders of record of Hornbeck common stock, $.10
par value per share ("Hornbeck Common Stock"), at the close of business on
January 31, 1996 (the "Record Date") are entitled to notice of and to vote at
the Special Meeting. On the Record Date, there were 13,234,728 shares of
Hornbeck Common Stock outstanding, with each share of Hornbeck Common Stock
entitled to cast one vote with respect to each matter properly presented at the
Special Meeting. See "The Special Meeting."
    
PURPOSE OF THE SPECIAL MEETING

     At the Special Meeting, holders of Hornbeck Common Stock will be asked to
adopt the Agreement and Plan of Merger dated December 21, 1995 (the "Merger
Agreement") among Hornbeck, Tidewater Inc., a Delaware corporation
("Tidewater"), and Tidewater Expansion, Inc., a Delaware corporation and
wholly owned subsidiary of Tidewater ("Newco"), pursuant to which, among other
things, Newco will be merged with and into Hornbeck (the "Merger") and
Hornbeck will become a wholly owned subsidiary of Tidewater. See "The Special
Meeting -- Purpose of the Special Meeting" and "The Merger."

QUORUM; VOTE REQUIRED

     Hornbeck's bylaws provide that the holders of a majority of the issued
and outstanding Hornbeck Common Stock must be in attendance at the Special
Meeting in person or by proxy in order for a quorum to be properly
constituted.

     Under Hornbeck's Certificate of Incorporation, the affirmative vote of
holders of not less than 66 2/3% of the total issued and outstanding shares of
Hornbeck Common Stock is required to adopt the Merger Agreement. See "The
Special Meeting -- Quorum; Vote Required."

     As of the Record Date, the directors and executive officers of Hornbeck
as a group had the power to vote approximately 2,008,477 shares of Hornbeck
Common Stock, or 15.2% of the outstanding shares of Hornbeck Common Stock
entitled to vote at the Special Meeting.

STRUCTURE OF THE MERGER AND MERGER CONSIDERATION

     Pursuant to the Merger Agreement, upon consummation of the Merger, Newco
will merge into Hornbeck and each share of Hornbeck Common Stock that is
issued and outstanding at the Effective Time (as defined below) will be
converted, subject to the adjustment discussed in the following sentence, into
the right to receive .667 of a share of common stock, $.10 par value per
share, of Tidewater (the "Tidewater Common Stock"), together with certain
associated rights under the Tidewater Restated Rights Agreement dated as of
December 17, 1993, by and between Tidewater and the First National Bank of
Boston, as rights agent (the "Tidewater Stockholder Rights Plan"). The Merger
Agreement provides that if the Average Market Price (as defined below) of a
share of Tidewater Common Stock is less than $24.50 or exceeds $32.50, then
the conversion ratio will be
                                        6
<PAGE>
   
adjusted, provided that the conversion ratio, as so adjusted, will not be less
than .60 (if the Average Market Price is more than $32.50) or greater than .74
(if the Average Market Price is less than $24.50) (as so adjusted, the
"Conversion Ratio"). The Merger Agreement further provides that either Hornbeck
or Tidewater may terminate the Merger Agreement if the Conversion Ratio at the
date of closing of the Merger would be less than .60 or greater than .74, by
virtue of the Average Market Price being greater than $36.13 or less than
$22.08. The term "Average Market Price" is defined as the average of the daily
closing sale prices of a share of Tidewater Common Stock on the New York Stock
Exchange as reported in THE WALL STREET JOURNAL for the ten consecutive trading
days that end on the second trading day immediately prior to the date of the
closing of the Merger. Each holder of Hornbeck Common Stock entitled upon
conversion to a fractional share of Tidewater Common Stock will, in lieu
thereof, receive a cash payment (without interest) equal to the product of the
Average Market Price and such fraction. See "The Merger -- Structure and Terms
of the Merger."

     The following table sets forth examples of the shares of Tidewater Common
Stock into which each share of Hornbeck Common Stock would be converted on the
Effective Date, and the aggregate dollar value of the shares of Tidewater
Common Stock that would be issued in the Merger, assuming that on such date
the Average Market Price for Tidewater Common Stock is as specified below and
that the maximum of 13,510,336 shares of Hornbeck Common Stock were converted
in the Merger.

</TABLE>
     On February 1, 1996, the closing sale price for a share of Tidewater Common
Stock was $35.00, and if such date had been the date of closing of the Merger,
the Average Market Price would have been $31.90. If the Average Market Price
exceeds $36.13, the Conversion Ratio would be less than .60 and either Hornbeck
or Tidewater would have the right to terminate the Merger Agreement.

     Tidewater and Hornbeck each have received an opinion of their respective
tax advisors that the Merger will qualify as a tax-free reorganization under
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Internal
Revenue Code"). In addition, Tidewater has received an opinion of KPMG Peat
Marwick LLP, the independent public accountants for Tidewater, that Tidewater is
eligible to be a party to a merger accounted for as a pooling of interests, and
such accounting firm is not aware of any matters that would preclude the use of
pooling-of-interests accounting in connection with the Merger. Additionally,
Hornbeck has received a letter from Price Waterhouse LLP, the independent
accountants for Hornbeck, that as a result of specified procedures, no matters
came to the attention of such firm that would preclude Tidewater from accounting
for the Merger as a pooling of interests. The tax and pooling opinions or
letters will be confirmed by such tax advisors and accountants immediately
before the date of closing of the Merger. See "The Merger -- Certain Federal
Income Tax Consequences" and " -- Accounting Treatment."
    
BOARD RECOMMENDATION

     THE HORNBECK BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE IN FAVOR OF THE MERGER

     Promptly following consummation of the Merger, each person who is a

EFFECTIVE TIME; EFFECTIVE DATE OF THE MERGER

     The Merger will become effective at the time (the "Effective Time") and
on the date (the "Effective Date") the Certificate of Merger is filed with the
Secretary of State of Delaware. Unless Tidewater and Hornbeck otherwise agree,
the Merger will be consummated as soon as practicable following receipt of
Hornbeck stockholder and necessary regulatory approvals and satisfaction or
waiver of the other conditions to the Merger. Tidewater and Hornbeck
anticipate that the Merger will be consummated as soon as practicable
following the Special Meeting. See "The Merger -- Hart-Scott-Rodino Clearance"
and " -- Other Conditions to the Merger."

REASONS FOR THE MERGER

     TIDEWATER.  Recognizing that the average age of its own worldwide fleet
of vessels, as well as the vessel fleets of its competitors, is continuing to
increase, and that the construction of new vessels is not yet economically
justifiable in view of the prevailing level of vessel day rates and the
continuing volatility in oil and gas prices, Tidewater has, from time to time,
sought to identify suitable vessel acquisition opportunities to strengthen and
better manage the attrition of its fleet and to continue to respond to
customer demands. The Board of Directors of Tidewater (the "Tidewater Board")
believes that there are several benefits that should accrue to Tidewater and
its stockholders following the Merger, including (i) Tidewater's increased
ability to service the Gulf of Mexico market, which many

                                      8
<PAGE>

industry analysts believe has a very positive outlook for the foreseeable
future, through the combination of the respective Gulf of Mexico operations of
Tidewater and Hornbeck; (ii) the ability of Tidewater to mitigate the effects
of the aging of the Tidewater fleet in the Gulf of Mexico through the
replacement of older Tidewater vessels with those Hornbeck vessels having
longer remaining useful lives; and (iii) the ability to achieve cost savings
and other operational benefits through the consolidation of overlapping
facilities as well as the elimination of duplicative corporate and
administrative functions.
   
     HORNBECK.  The Hornbeck Board believes that Tidewater is a strong and
growing energy services company and that the proposed transaction provides an
opportunity for the holders of Hornbeck Common Stock to participate in a
combined enterprise that has significantly greater business and financial
resources than Hornbeck would have if the Merger did not take place and to
receive, on a tax-deferred basis, a premium for their Hornbeck Common Stock
based on the market prices of the Hornbeck Common Stock prior to the November
20, 1995 announcement of the proposed Merger. The Hornbeck Board believes that
among the benefits of the Merger to the holders of the Hornbeck Common Stock are
(i) the geographical distribution of the combined entity's marine assets, with a
consequent reduction in exposure to industry business cycles in the Gulf of
Mexico, (ii) the complementary nature of the Tidewater and Hornbeck fleets,
which would add strength and depth to the combined entity's fleet, (iii) the
enhanced growth opportunities for the combined entity from expanded geographic
presence and greater resources, (iv) Tidewater's position as one of the larger
participants in the U.S. gas compression business and (v) the potential cost
savings achieved through consolidation. In evaluating the fairness of the
proposed merger consideration to the Hornbeck stockholders, the Hornbeck Board
considered, among other things, (i) Tidewater's recent historical increases in
financial performance, including earnings per share, in combination with a
relatively unleveraged balance sheet, (ii) the premium being offered with
respect to the Hornbeck Common Stock as compared to comparable transactions and
public market valuation of comparable companies, (iii) the structure of the
transaction as a tax-free reorganization, (iv) the greater liquidity of
Tidewater Common Stock, (v) recent and historical market prices and valuation
ratios of Hornbeck Common Stock and Tidewater Common Stock, (vi) analysis of the
background and experience of Tidewater management and (vii) the opinion of
Simmons & Company International, as financial advisor to Hornbeck, that is
described below.
    
OPINION OF INVESTMENT BANKING FIRM

     The investment banking firm of Simmons & Company International
("Simmons") has acted as financial advisor to Hornbeck in connection with the
proposed Merger and has delivered a letter to the Hornbeck Board stating that,
in its opinion, the consideration to be paid by Tidewater, as expressed by the
Conversion Ratio, is fair to Hornbeck and the holders of Hornbeck Common Stock
from a financial point of view. Hornbeck has agreed to pay Simmons for its
services in assisting the Hornbeck Board in analyzing the proposed Merger and
in rendering the opinion referred to above a fee equal to 0.9% of the
aggregate market value of the shares of Hornbeck Common Stock outstanding at
the Effective Time of the Merger. In addition, Hornbeck has agreed to
reimburse Simmons for its out-of-pocket expenses and to indemnify Simmons
against certain liabilities that may be incurred in connection with providing
such services. The full text of the Simmons letter is attached to this Proxy
Statement/Prospectus as Appendix B. See "The Merger -- Opinion of Investment
Banking Firm."

OTHER TERMS AND CONDITIONS OF THE MERGER

     In addition to the foregoing matters, the Merger Agreement contains
certain other terms and conditions, including:

     HART-SCOTT-RODINO CLEARANCE.  The obligations of Hornbeck and Tidewater
to consummate the Merger are subject to the expiration or earlier termination
of the requisite waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"). In addition, it

                                      9
<PAGE>
   
is a condition to Tidewater's obligation to consummate the Merger that such
expiration or earlier termination be accomplished without the imposition of a
condition on Hornbeck or Tidewater that would require the divestiture by either
Hornbeck or Tidewater of any asset of either party or that would otherwise have
a material adverse effect on Tidewater or Hornbeck. On January 2, 1996 Hornbeck
and Tidewater each made their required initial filings under the HSR Act. The
waiting period expired on February 1, 1996, without any further request for
additional information. See "The Merger -- Hart-Scott-Rodino Clearance."
    
     OTHER CONDITIONS TO THE MERGER.  In addition to Hornbeck stockholder
approval and HSR Act clearance, the consummation of the Merger is conditioned
upon the satisfaction of certain conditions set forth in the Merger Agreement,
including the receipt by each party of customary legal opinions, certificates,
consents, resolutions and reports from the other and from third parties and
confirmation of the tax opinions and accountants' opinions or letters
described above. Tidewater and Hornbeck intend to consummate the Merger as
soon as practicable following satisfaction or waiver of the conditions
thereto. See "The Merger -- Other Conditions to the Merger," "-- Certain
Federal Income Tax Consequences" and "-- Accounting Treatment."

     APPOINTMENT TO TIDEWATER BOARD; CONSULTING AGREEMENT.  Effective on the
second day following the Effective Date, Larry D. Hornbeck, Chairman of the
Board, President and Chief Executive Officer of Hornbeck, will be appointed to
the class of the Tidewater Board with a term expiring at the annual meeting of
Tidewater's stockholders that next follows the Effective Date. Mr. Hornbeck
will also enter into a consulting agreement with Tidewater effective as of the
Effective Date which provides that he will be recommended by the Tidewater
Board for reelection at such annual meeting to a full three-year term. See
"The Merger -- Interests of Certain Persons in the Merger."

     CERTAIN EMPLOYEE MATTERS.  At the time of execution of the Merger
Agreement, there were approximately 317,654 unissued shares of Hornbeck Common
Stock subject to unexercised stock options that were previously granted to
officers and employees of Hornbeck under its 1989 and 1993 Employee Incentive
Plans. Under the terms of the agreements pursuant to which such options were
granted, any options not previously vested that were granted under the 1989
Employee Incentive Plan became fully vested and exercisable upon approval of
the Merger by the Hornbeck Board and any options not previously vested that
were granted under the 1993 Employee Incentive Plan will become fully vested
and exercisable upon consummation of the Merger. Holders of any options that
are not exercised for Hornbeck Common Stock by the Effective Time will have
the right, upon exercise of such options in accordance with their terms, to
acquire that number of shares of Tidewater Common Stock that the holder of
such unexercised options would have been entitled to receive upon consummation
of the Merger if such holder had exercised such options for shares of Hornbeck
Common Stock prior to or coincident with the Merger. See "The
Merger -- Interests of Certain Persons in the Merger."

     Under the terms of the Merger Agreement, Hornbeck may make cash payments
of up to $350,000 in the aggregate (the "1995 Incentive Cash Payments") and
issue an aggregate of up to 19,310 shares of restricted Hornbeck Common Stock
to its directors, officers and employees as semi-annual director fees and
incentive payments for 1995 performance. In addition, the Merger Agreement
provides that, if the Merger has not been consummated by April 30, 1996,
Hornbeck may make additional cash payments to its officers and employees as
incentive payments for 1996 performance through the Effective Date in amounts
to be pro rated and based on the total 1995 Incentive Cash Payments. See "The
Merger -- Interests of Certain Persons in the Merger."

     The Hornbeck Board has adopted a severance policy for Hornbeck's
employees and Tidewater has agreed to honor the terms thereof. Pursuant to
such policy, Hornbeck employees who are not parties to the change in control
agreements discussed below will be entitled to receive certain

                                      10
<PAGE>
severance payments and continuation, for a limited time, of certain employee
benefits. See "The Merger -- Interests of Certain Persons in the Merger."
   
     CHANGE IN CONTROL AGREEMENTS.  Four executive officers of Hornbeck entered
into change of control agreements in June 1995. On December 29, 1995, Hornbeck
made certain advance payments to three executive officers of a portion of the
amounts to which such officers would have otherwise become entitled following
consummation of the Merger under the terms of change in control agreements
between Hornbeck and such executive officers. For additional information on such
payments, which were made by Hornbeck to minimize certain income tax costs to
Hornbeck and such individuals, see "The Merger -- Interests of Certain Persons
in the Merger."
    
     INDEMNIFICATION COVENANTS.  The Merger Agreement provides that Tidewater
will indemnify and hold harmless each person who was an officer or director of
Hornbeck or any of its subsidiaries on December 21, 1995 or who previously
served as such at any time after January 1, 1993, from and against all
damages, liabilities, judgments and claims based upon or arising out of such
person's service in such capacity to the same extent as he or she would have
been indemnified under the Restated Certificate of Incorporation or Restated
Bylaws of Hornbeck as they were in effect on the date the Merger Agreement was
executed. With certain exceptions, the aggregate amount of indemnification
payments required to be made by Tidewater to such persons is limited to $50
million. Tidewater has also agreed to pay the insurance premiums required for
any extension of Hornbeck's director's and officer's insurance policy
following the Effective Date for a period of six years or to provide
comparable coverage under a Tidewater policy. See "The Merger -- Interests of
Certain Persons in the Merger."

     NO SOLICITATION OF TRANSACTIONS; TERMINATION FEE.  The Merger Agreement
prohibits Hornbeck and its subsidiaries and the affiliated entities in the
North Sea Group from, directly or indirectly, soliciting or encouraging the
initiation or submission of any inquiries, proposals or other offers regarding
any acquisition, merger, takeover bid, sale of all or substantially all of its
assets, or sales of shares of capital stock of Hornbeck or similar
transactions involving Hornbeck. The Merger Agreement provides that if the
Hornbeck Board decides after considering advice of outside counsel and
financial advisors that it would be consistent with its fiduciary
responsibilities to approve or recommend another transaction in lieu of the
Merger and therefore withdraws or modifies its recommendation that the Merger
Agreement be adopted, Hornbeck may not enter into any agreement for such other
takeover proposal until the Merger Agreement is terminated and a termination
fee of $6 million in cash (the "Termination Fee") is paid to Tidewater.
Hornbeck's obligation to pay the Termination Fee is not incurred if Hornbeck
or Tidewater otherwise terminates the Merger Agreement in accordance with its
terms. See "The Merger -- No Solicitation of Transactions; Termination Fee."

     AMENDMENT, WAIVER AND TERMINATION.  Hornbeck and Tidewater may mutually
agree to amend the Merger Agreement at any time before or after Hornbeck
stockholder approval, provided that no amendment is permissible following
Hornbeck stockholder approval if the amendment would by law require further
stockholder approval, unless such further stockholder approval is obtained.
Either party may waive compliance with any of the agreements or conditions
contained in the Merger Agreement other than the satisfaction of all
requirements prescribed by law for consummation of the Merger.

     The Merger Agreement may be terminated at any time before the Effective
Time (i) by the mutual consent of the Hornbeck Board and the Tidewater Board
or (ii) by the board of directors of either party if (a) the required approval
by Hornbeck's stockholders is not obtained at the Special Meeting, (b) there
has been a material breach by the other party of any representation, warranty
or covenant in the Merger Agreement which is not cured within 15 days after
notice of such breach is given to the breaching party, (c) all conditions to
closing have not been met by, or the Merger has not been consummated on or
before, November 20, 1996 unless the party seeking to terminate the Merger
Agreement is, at such time, in willful and material violation of its
representations, warranties or covenants under the Merger Agreement, (d) any
governmental entity shall have issued an order,

                                      11
<PAGE>
   
decree, or ruling or taken any other action permanently enjoining, restraining
or otherwise prohibiting the Merger and such order, decree, ruling or other
action shall have become final and nonappealable, or (e) at the date of closing
of the Merger, the Conversion Ratio would be less than .60 or greater than .74.
Also, Hornbeck may terminate the Merger if the Hornbeck Board withdraws its
recommendation of the Merger to the holders of Hornbeck Common Stock in
connection with its approval or recommendation to the holders of Hornbeck Common
Stock of any alternate proposal and pays the Termination Fee to Tidewater. See
"The Merger -- No Solicitation of Transactions; Termination Fee" and "--
Amendment; Waiver; Termination."
    
APPRAISAL RIGHTS

     Under Delaware law, Hornbeck stockholders are not entitled to any
appraisal or dissenters' rights in connection with the Merger.

NOTICE TO NON-U.S. CITIZENS

     Under federal maritime laws, neither Hornbeck nor Tidewater are permitted
to continue to engage in the United States coastwise trade if persons other
than United States citizens own more than 25% of their respective shares of
outstanding common stock. Tidewater's Certificate of Incorporation and Bylaws
contain provisions designed to enable Tidewater to establish the citizenship
of its stockholders in a manner satisfactory under the maritime laws and to
assure that non-citizens will not own more than 25% of the outstanding
Tidewater Common Stock. Under these provisions, if the number of shares of
Tidewater Common Stock owned by non-citizens were to exceed 24%, Tidewater may
deny voting rights and withhold dividends with respect to the excess shares
and may redeem the excess shares. Moreover, any transfer or purported transfer
of shares of Tidewater Common Stock that would result in the ownership by
non-citizens of more than 24% of the then outstanding Tidewater Common Stock
will not be effective against Tidewater except for the purposes of effecting
the remedies described above.

     Upon consummation of the Merger, a letter of transmittal to be used in
connection with the exchange of certificates representing shares of Hornbeck
Common Stock for certificates representing Tidewater Common Stock will be
mailed to each holder of Hornbeck Common Stock as of the Effective Date. The
letter of transmittal will contain a citizenship certificate that must be
completed and returned by such holders before certificates representing
Tidewater Common Stock will be issued and delivered.

     The payment of dividends on Tidewater Common Stock and its preferred
stock are subject to limitations under Tidewater's revolving credit and term
loan agreement, although no preferred stock is currently outstanding. None of
such limitations are currently expected to restrict Tidewater's continued
payment of dividends at current levels. A further discussion of this matter is
contained in Note 7 of the Notes to Tidewater's Consolidated Financial
Statements included elsewhere herein. As a result of the timing of the fiscal
1994 Tidewater Board meetings, only three quarterly dividends were declared
during fiscal 1994 with respect to Tidewater Common Stock.

     On November 17, 1995, the last trading day before the date that Tidewater
and Hornbeck publicly announced the proposed Merger, the closing sale price
for a share of Tidewater Common Stock on the New York Stock Exchange was
$28 3/4. No assurance can be given as to the Average Market Price or the
market price of Tidewater Common Stock at the Effective Time.

     Hornbeck has never paid cash dividends on the Hornbeck Common Stock, and
Hornbeck's ability to pay cash dividends in the future is limited by its
current debt arrangements.

     On November 17, 1995, the last trading day before the date that Tidewater
and Hornbeck publicly announced the proposed Merger, the closing sale price
for a share of Hornbeck Common Stock on the Nasdaq National Market was

Stock at the Effective Time.

COMPARATIVE PER SHARE DATA

     Set forth below are earnings from continuing operations, cash dividends
declared and book value per common share data of Tidewater and Hornbeck on
both historical and pro forma combined bases and on a per share equivalent pro
forma basis for Hornbeck. Pro forma combined earnings from continuing
operations per share is derived from the pro forma combined information
presented elsewhere herein, which gives effect to the Merger under the
pooling-of-interests accounting method as if the Merger had occurred at
September 30, 1995, and after certain adjustments necessary to conform the
basis of presentation of the Tidewater and Hornbeck information. Pro forma

connection with the Special Meeting at a cost of approximately $4,000, plus
out-of-pocket expenses. Arrangements will also be made with custodians, nominees
and fiduciaries for forwarding proxy solicitation materials to beneficial owners
of Hornbeck Common Stock held of record by such custodians, nominees and
fiduciaries, all of whom will be reimbursed for reasonable expenses incurred in
connection therewith. This Proxy Statement/Prospectus and the accompanying proxy

"Merger Agreement") among Hornbeck, Tidewater Inc., a Delaware corporation
("Tidewater"), and Tidewater Expansion, Inc., a Delaware corporation and
wholly owned subsidiary of Tidewater ("Newco").

     The Hornbeck Board knows of no other matter to be presented at the

the Corporate Secretary of Hornbeck at or prior to the Special Meeting a
written revocation bearing a later date or a duly executed later-dated proxy
relating to the same shares; or (ii) attending the Special Meeting and voting

constitute a revocation of a proxy. Any written revocation or later-dated
proxy should be delivered at the Special Meeting to the Corporate Secretary of
Hornbeck or before the Special Meeting to Hornbeck at 7707 Harborside Drive,
Galveston, Texas 77554, Attention: Corporate Secretary.

                                   THE MERGER

THE MERGER AGREEMENT

     The Merger is to be effected in accordance with the terms and conditions
set forth in the Merger Agreement, a copy of which is attached hereto as
Appendix A and incorporated herein by reference. The following brief
description is necessarily incomplete and is qualified in its entirety by
reference to the Merger Agreement.

STRUCTURE AND TERMS OF THE MERGER

     On December 21, 1995, the Merger Agreement was executed by and among
Tidewater and Newco, on the one hand, and Hornbeck, on the other hand.
Pursuant to the Merger Agreement, at the Effective Time, Newco will merge into
Hornbeck, Hornbeck will become a wholly owned subsidiary of Tidewater, and
each share of Hornbeck Common Stock that is then outstanding will be converted
into the right to receive .667 of a share of the common stock, $.10 par value
per share, of Tidewater (the "Tidewater Common Stock"), together with
associated rights under Tidewater's Restated Rights Agreement dated as of
December 17, 1993 by and between Tidewater and the First National Bank of
Boston, as rights agent (the "Tidewater Stockholder Rights Plan") subject to
adjustment as described below (as so adjusted, the "Conversion Ratio").
   
     The Merger Agreement provides that if the Average Market Price of a share
of Tidewater Common Stock is (a) less than $24.50, then the Conversion Ratio
shall equal that number obtained by dividing $16.34 by the Average Market Price,
or (b) greater than $32.50, then the Conversion Ratio shall equal that number
obtained by dividing $21.68 by the Average Market Price; provided that in no
event shall the Conversion Ratio, as so adjusted, be less than .60 or greater
than .74, by virtue of the Average Market Price being greater than $36.13 or
less than $22.08. The "Average Market Price" is defined as the average of the
daily closing sale prices of a share of Tidewater Common Stock on the New York
Stock Exchange as reported in THE WALL STREET JOURNAL for the ten consecutive
trading days that end on the second trading day before the date of closing of
the Merger. Holders of Hornbeck Common Stock who, upon conversion, would be
entitled to a fractional share of Tidewater Common Stock will, in lieu thereof,
receive a cash payment equal to the product of such fraction and the Average
Market Price.
    
     The following table sets forth examples of the shares of Tidewater Common
Stock into which each share of Hornbeck Common Stock would be converted on the
Effective Date, and the aggregate dollar value of the shares of Tidewater
Common Stock that would be issued in the Merger, assuming that on such date
the Average Market Price for Tidewater Common Stock is as specified below and
that the maximum of 13,510,336 shares of Hornbeck Common Stock were converted
in the Merger.

                 $ 28.50                                   .667                     $256.8 million
                 $ 32.50                                   .667                     $292.9 million
                 $ 36.13                                   .60                      $292.9 million
</TABLE>
     On February 1, 1996, the closing sale price for a share of Tidewater Common
Stock was $35.00, and if such date had been the date of closing of the Merger,
the Average Market Price would have been $31.90. If the Average Market Price
exceeds $36.13, the Conversion Ratio would be less than .60 and either Hornbeck
or Tidewater would have the right to terminate the Merger Agreement.
    
BACKGROUND OF THE MERGER

     Tidewater has from time to time evaluated various opportunities to expand
the size of its marine fleet and recently identified Hornbeck as an attractive
candidate for a business combination for the reasons described in "-- Reasons
for the Merger."

                                      18
<PAGE>
   
     In late October 1995, Mr. William C. O'Malley, Chairman of the Board,
President and Chief Executive Officer of Tidewater, expressed an initial
interest in the possible acquisition of Hornbeck to a representative of Simmons
& Company International ("Simmons"), an investment banking firm regularly
retained by Hornbeck with respect to previous mergers and acquisitions
undertaken or evaluated by Hornbeck that had also on two occasions acted as
co-manager of an underwriting syndicate in a public securities offering of
Tidewater Common Stock involving a selling stockholder. Subsequently, Mr.
O'Malley had a preliminary discussion with Mr. Larry D. Hornbeck, Chairman of
the Board, President and Chief Executive Officer of Hornbeck, during which Mr.
O'Malley indicated an interest in exploring a possible transaction between
Tidewater and Hornbeck. Consistent with the role that Simmons has previously
performed in assisting with the evaluation of potential transactions involving
Hornbeck, Simmons was authorized by Mr. Hornbeck to explore with Tidewater
representatives the extent of Tidewater's interest and whether a Tidewater
proposal would merit Hornbeck Board consideration. After discussions with
representatives of Simmons in early November, Tidewater requested that Simmons
contact Mr. Hornbeck in order to obtain, subject to a confidentiality agreement,
confidential financial and operational information regarding Hornbeck for
purposes of confirming its interest. Tidewater spent several days in early
November evaluating the Hornbeck material supplied to it during which time
Tidewater also had several discussions with Simmons concerning pricing and other
terms of a possible letter of intent.
    
     On Monday, November 13, Mr. O'Malley convened a special meeting of the
board of directors of Tidewater (the "Tidewater Board"). Mr. O'Malley advised
the Tidewater Board of the preliminary discussions with Mr. Hornbeck and
Simmons representatives, and sought the Tidewater Board's authority for Mr.
O'Malley, as Chief Executive Officer of Tidewater, to extend an offer to
Hornbeck to acquire Hornbeck in a stock for stock merger that would qualify as
a tax free reorganization as well as qualifying for pooling-of-interests
accounting treatment. At that same meeting, Simmons was invited to make a
presentation to the Tidewater Board. The presentation followed an explanation
by Mr. O'Malley to the Tidewater Board that Simmons had historically
represented Hornbeck as a financial advisor and would be representing Hornbeck
in connection with a possible transaction with Tidewater. Simmons had been
invited by Mr. O'Malley to make a presentation to the Tidewater Board, with
the permission of Mr. Hornbeck, because, in its preliminary consideration of a
possible transaction, Simmons had prepared certain substantive analyses of the
benefits of a combination of Tidewater and Hornbeck. After completing its
presentation, Simmons was excused from the meeting and the Tidewater Board
continued to discuss the potential transaction. At the conclusion of the
meeting, the Tidewater Board, based on the recommendation of management and
its own independent assessment, authorized Mr. O'Malley to make an offer to
Hornbeck consistent with the proposal discussed at the meeting. On Tuesday,
November 14, Tidewater delivered a draft letter of intent to Simmons for
consideration.

     Discussions and negotiations were held on November 14 and 15 between
Tidewater and Simmons concerning the letter of intent and Simmons concluded
and so advised Mr. Hornbeck that the proposal embodied in the draft letter of
intent merited consideration by the Hornbeck Board. The terms of the proposal
were not made available to any member of the Hornbeck Board, including Mr.
Hornbeck, until the special Hornbeck Board meeting on November 16.

     At the special Hornbeck Board meeting held on November 16, 1995, Simmons
made a detailed presentation covering the businesses, markets and operations
of Hornbeck and Tidewater, an analysis of potential combination benefits, an
analysis of the transaction value under the proposed acquisition structure,
and a comparative analysis of various public market trading multiples of
companies deemed comparable to Hornbeck, various acquisition multiples of
transactions deemed comparable and the proposed acquisition multiples for
Hornbeck. Simmons also presented an analysis of public market trading
multiples for Tidewater and various companies selected as comparable to
Tidewater. Further, Simmons presented to the Hornbeck Board a pro forma review
of Hornbeck and Tidewater on a combined basis. In addition, the Hornbeck Board
reviewed the progress made toward and the likelihood of other possible
acquisition opportunities for Hornbeck consistent with its previously

                                      19
 <PAGE>

announced business strategy of growth through acquisitions, including the
recent inability to generate suitable acquisition candidates on acceptable
terms and conditions.

     Consistent with the Hornbeck Board's fiduciary duty, a committee of two
directors was appointed as a negotiating committee for the Hornbeck Board. The
Hornbeck Board and its financial advisors were also encouraged to consider any
further questions, to further analyze the advantages, disadvantages, options
and/or alternatives to the transaction and to raise such matters for
discussion at a second Hornbeck Board meeting to be held on November 19, 1995.

     Following an exchange of views with respect to certain terms to be
incorporated in a letter of intent, Hornbeck invited Tidewater representatives
to a negotiating session in Houston on Friday, November 17. During the period
from November 17 through 19, 1995, the Hornbeck Board committee negotiated the
terms of a letter of intent with representatives of Tidewater. The full
Hornbeck Board convened again on November 19, 1995, and considered further the
advantages and disadvantages of a potential transaction; all directors were
given opportunities for comments, questions, and discussion of alternatives.
The Hornbeck Board received verbal assurances from Simmons that the proposed
Merger was fair to the holders of Hornbeck Common Stock from a financial point
of view subject to Simmons' review of the terms of a merger agreement to be
executed in connection with the proposed Merger and completion by Hornbeck of
its due diligence review. At the conclusion of the November 19, 1995 Hornbeck
Board meeting, the Hornbeck Board approved the execution of a letter of intent
and negotiation of a definitive agreement. On the evening of November 19,
1995, Hornbeck and Tidewater executed a letter of intent, and a press release
concerning the proposed Merger was released on the morning of November 20,
1995.
   
     Between November 20, 1995 and December 21, 1995, Hornbeck and Tidewater
representatives negotiated the Merger Agreement. The Tidewater Board met on
December 13, 1995 and, after reviewing the terms of the Merger Agreement with
Tidewater's management, legal counsel and outside financial advisors, Merrill
Lynch & Co. ("Merrill Lynch"), approved the Merger Agreement and the
transactions contemplated thereby. The Hornbeck Board met again on December 14,
1995. After discussion of the terms of the Merger Agreement, consideration of
the reaction of analysts and the marketplace to the announcement of the Merger
and a verbal confirmation by Simmons that the proposed Merger was fair to the
holders of Hornbeck Common Stock, the Hornbeck Board approved the Merger
Agreement and the transactions contemplated thereby and unanimously recommended
the adoption of the Merger Agreement by the holders of the Hornbeck Common
Stock. Subsequently, Simmons confirmed its fairness opinion in writing effective
as of the date of execution of the Merger Agreement. See "-- Opinion of
Investment Banking Firm" and Appendix B hereto.
    
REASONS FOR THE MERGER

     TIDEWATER.  Recognizing that the average age of its own worldwide fleet
of vessels, as well as the vessel fleets of its competitors, is continuing to
increase, and that the construction of new vessels is not yet economically
justifiable in view of the prevailing level of vessel day rates and the
continuing volatility in oil and gas prices, Tidewater has sought, from time
to time, to identify suitable vessel acquisition opportunities to strengthen
and better manage the attrition of its fleet and to continue to respond to
customer demands. Tidewater's decision to pursue the acquisition of Hornbeck
is consistent with this overall strategy.

     The Tidewater Board believes that there are several benefits that should
accrue to Tidewater and its stockholders following the Merger, including (i)
Tidewater's increased ability to service the Gulf of Mexico market, which many
industry analysts believe has a very positive outlook for the foreseeable
future, through the combination of the respective Gulf of Mexico operations of
Tidewater and Hornbeck; (ii) the ability of Tidewater to mitigate the effects
of the aging of the Tidewater fleet in the Gulf of Mexico through the
replacement of older Tidewater vessels with those Hornbeck vessels having
longer remaining useful lives; and (iii) the ability to achieve cost savings
and other operational
                                      20

benefits through the consolidation of overlapping facilities as well as the
elimination of duplicative corporate and administrative functions.

     In reaching its decision to approve the Merger Agreement, the Tidewater
Board considered the following factors, among others: (i) the recent and
historical performance of the Tidewater Common Stock and Hornbeck Common
Stock, (ii) certain historical and prospective financial information of
Hornbeck, (iii) an analysis of recent acquisitions in comparable industries
and (iv) the terms of the Merger Agreement. Prior to taking action on the
Merger Agreement, the Tidewater Board received presentations from, and
reviewed the terms and conditions of the Merger Agreement with, Tidewater's
management, legal counsel, and Tidewater's outside financial advisors, Merrill
Lynch. The Tidewater Board considered a number of factors in addition to those
disclosed above, and did not quantify or otherwise attempt to assign relative
weights to the specific factors considered. THE TIDEWATER BOARD HAS
UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND BELIEVES THE MERGER AND OTHER
TRANSACTIONS CONTEMPLATED THEREIN TO BE IN THE BEST INTERESTS OF TIDEWATER AND
ITS STOCKHOLDERS.

     HORNBECK.  The Hornbeck Board believes that Tidewater is a strong and
growing energy service company and that the proposed transaction provides an
opportunity for Hornbeck's stockholders to participate in a combined
enterprise that has significantly greater business and financial resources
than Hornbeck would have if the Merger did not take place, and to receive, on
a tax-deferred basis, a premium for their Hornbeck Common Stock based on
recent market prices. In view of the inherent benefits of the proposed Merger
with Tidewater, together with the opportunity of the Hornbeck Board to
consider other unsolicited offers consistent with the terms of the Merger
Agreement, the Hornbeck Board approved the terms of the Merger.
   
     The Hornbeck Board believes that among the benefits of the Merger to the
holders of the Hornbeck Common Stock are (i) the geographical distribution of
the combined entity's marine assets, with a consequent reduction in exposure to
industry business cycles in the Gulf of Mexico, (ii) the complementary nature of
the Tidewater and Hornbeck fleets, which would add strength and depth to the
combined entity's fleet, (iii) the enhanced growth opportunities for the
combined entity from expanded geographic presence and greater resources, (iv)
Tidewater's position as one of the larger participants in the U.S. gas
compression business and (v) the potential cost savings achieved through
consolidation.

     In evaluating the fairness of the proposed merger consideration to the
Hornbeck stockholders, the Hornbeck Board consulted with management and
Simmons regarding Tidewater's business and with management, legal counsel, tax
advisors and Simmons regarding the terms and provisions of the Merger
Agreement. The Hornbeck Board considered a number of factors, many of the
detailed analyses with respect to which were prepared by Simmons, in reaching
its conclusions including: (i) an analysis of the financial performance,
operations, assets, business condition and business prospects of Tidewater and
Hornbeck, including each of Hornbeck's and Tidewater's projected performance
through 1996; (ii) a review of pro forma projections of the combined entity;
(iii) Tidewater's history over the past several years of increases in
financial performance, including earnings per share, while maintaining a
relatively unleveraged balance sheet; (iv) the premium offered with respect to
the Hornbeck Common Stock in the proposed Merger and a comparison of the
valuation multiples implied in the Conversion Ratio to that of other
comparable publicly traded energy service companies and comparable
transactions; (v) the benefits of a proposed tax-free reorganization
structure; (vi) the greater liquidity provided by Tidewater Common Stock with
over 60 million shares outstanding following the Merger, compared to over 13
million shares outstanding for Hornbeck before the Merger, together with
expanded analyst coverage and potentially greater investor interest; (vii) the
historical performance of the Tidewater Common Stock and the Hornbeck Common
Stock and various current and historical valuation multiples of the two
companies; (viii) an analysis of the background and experience of Tidewater's
management team; and (ix) other elements of the presentation and advice of and
other materials prepared by Simmons and the opinion of Simmons, as financial
advisor to Hornbeck, that the consideration to be received by the stockholders
of Hornbeck in the Merger was fair from a financial point of view to Hornbeck
stockholders.
    
                                      21
<PAGE>
   
     The Hornbeck Board also considered the terms of the Merger Agreement,
including provisions that permit the Hornbeck Board, consistent with the
exercise of its fiduciary duties and subject to certain conditions, to respond
to inquiries regarding other potential business combination transactions, to
provide information to, and negotiate with, third parties making an unsolicited
proposal to acquire Hornbeck in such a transaction and to terminate the Merger
Agreement if the Hornbeck Board determines to recommend an alternative business
combination as a Superior Proposal (as defined in "-- No Solicitation of
Transactions, Termination Fee" below). In that regard, the Hornbeck Board noted
that the Merger Agreement provides that if the Merger Agreement is terminated as
a result of a Superior Proposal, Hornbeck will be obligated to pay Tidewater a
Termination Fee of $6 million in cash. The Hornbeck Board did not view the
Termination Fee provision of the Merger Agreement as unreasonably impeding any
interested third party from proposing a Superior Proposal.
    
     The Hornbeck Board believes that the terms of the Merger Agreement are
fair to and in the best interests of Hornbeck and the holders of the Hornbeck
Common Stock. In view of the variety of factors considered in connection with
its evaluation of the Merger, the Hornbeck Board did not quantify or otherwise
attempt to assign relative weights to the specific factors considered.

RECOMMENDATION OF THE HORNBECK BOARD

     AFTER CAREFUL CONSIDERATION, THE HORNBECK BOARD HAS DETERMINED THAT THE
MERGER IS ADVISABLE AND IN THE BEST INTEREST OF THE HOLDERS OF HORNBECK COMMON
STOCK, HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE MERGER AND
RECOMMENDS THAT HOLDERS OF HORNBECK COMMON STOCK VOTE "FOR" ADOPTION OF THE
MERGER AGREEMENT.

OPINION OF INVESTMENT BANKING FIRM

     The investment banking firm of Simmons & Company International
("Simmons") has acted as financial advisor to Hornbeck in connection with the
Merger and delivered its oral opinion to the Hornbeck Board at the Hornbeck
Board meetings on November 16 and December 14, 1995, which it subsequently
confirmed by its written opinion dated December 21, 1995, to the Hornbeck
Board to the effect that, as of such date, the consideration to be received by
the holders of shares of Hornbeck Common Stock is fair to such holders from a
financial point of view. Simmons was not asked to and did not recommend the
Conversion Ratio on which the amount of such consideration is based. The
Conversion Ratio was determined by the Tidewater Board and the Hornbeck Board
in arms-length negotiations. A copy of the opinion of Simmons is attached
hereto as Appendix B. Holders of Hornbeck Common Stock are urged to read the
opinion in its entirety for an explanation of the assumptions made, matters
considered and limits of the review undertaken by Simmons.

     In connection with rendering its verbal advice and its subsequent written
opinion, Simmons reviewed and analyzed, among other things, the following: (i)
the letter of intent between Tidewater and Hornbeck in draft form and as
executed on November 19, 1995; (ii) the Merger Agreement; (iii) the financial
statements and other information concerning Hornbeck, including the Annual
Reports on Form 10-K for each of the years in the three-year period ended
December 31, 1994, the Quarterly Reports on Form 10-Q of Hornbeck for the
quarters ended March 31, 1995, June 30, 1995 and September 30, 1995, and the
Current Reports on Form 8-K of Hornbeck related to events occurring on
November 15, 1994, as amended, June 20, 1995, and November 19, 1995; (iv)
certain other internal information, primarily financial in nature, concerning
the business and operations of Hornbeck furnished by Hornbeck for purposes of
Simmons' analysis; (v) certain publicly available information concerning the
trading of, and the trading market for, Hornbeck Common Stock; (vi) certain
publicly available information concerning Tidewater, including the Annual
Reports on Form 10-K of Tidewater for each of the fiscal years in the
three-year period ended March 31, 1995, the Quarterly Reports on Form 10-Q of
Tidewater for the quarters ended June 30, 1995 and September 30, 1995, and the
Current Reports on Form 8-K related to events occurring on November 30, 1994,
as amended, and January 5, 1995; (vii) certain other internal information,
primarily financial in nature, concerning the business and operations of
Tidewater furnished by Tidewater for purposes of Simmons' analysis; (viii)
certain

                                      22
 <PAGE>


publicly available information concerning the trading of, and the trading
market for, Tidewater Common Stock; (ix) certain publicly available
information with respect to certain other companies that Simmons believes to
be comparable to Hornbeck or Tidewater and the trading markets for certain of
such other companies' securities; (x) certain publicly available information
concerning the estimates of the future operating and financial performance of
Hornbeck, Tidewater and the comparable companies prepared by industry experts
unaffiliated with either Hornbeck or Tidewater; and (xi) certain publicly
available information concerning the nature and terms of certain other
transactions considered relevant to the inquiry. Further, Simmons made such
other analyses and examinations as deemed necessary or appropriate. Simmons
also met with certain officers and employees of Hornbeck and Tidewater to
discuss the foregoing, as well as other matters believed relevant to the
inquiry.

     In arriving at its opinion, Simmons assumed and relied upon the accuracy
and completeness of all of the financial and other information provided by
Hornbeck and Tidewater, or publicly available, including, without limitation,
information with respect to asset conditions, liability reserves and insurance
coverages, and did not attempt independently to verify any of such
information. Based on the terms set forth in the Merger Agreement, Simmons
also assumed that the proposed Merger would be treated for federal income tax
purposes as a reorganization within the meaning of Section 368 of the Internal
Revenue Code of 1986, as amended, and would be treated as a "pooling of
interests" for accounting purposes. Simmons did not conduct a physical
inspection of any of the assets, properties or facilities of Hornbeck or
Tidewater, nor did Simmons make or obtain any independent evaluations or
appraisal of any of such assets, properties or facilities.
   
     In conducting its analysis and arriving at its opinion, Simmons
considered such financial and other factors as it deemed appropriate under the
circumstances including, among others, the following: (i) the historical and
current financial position and results of operations of Hornbeck and
Tidewater; (ii) the business prospects of Hornbeck and Tidewater; (iii) the
historical and current market for Hornbeck Common Stock, for Tidewater Common
Stock and for the equity securities of certain other companies believed to be
comparable to Hornbeck or Tidewater; (iv) the respective contributions in
terms of various financial measures of Hornbeck and Tidewater to the combined
company, and the relative pro forma ownership of Tidewater after the proposed
Merger by the current holders of Hornbeck Common Stock and Tidewater Common
Stock; and (v) the nature and terms of certain other acquisition transactions
that Simmons believes to be relevant. Simmons also took into account its
assessment of general economic, market and financial conditions and its
experience in connection with similar transactions and securities' valuation
generally. Simmons' opinion necessarily was based upon conditions as they
existed and could be evaluated on, and on the information made available at, the
dates of its verbal advice and written opinion. Such opinion was confirmed in
writing by Simmons on February 5, 1996, based on conditions as they existed and
could be evaluated on such date.
    
     The Hornbeck Board selected Simmons as its financial advisor because
Simmons is a nationally recognized investment banking firm specializing in
service to the energy services industry with substantial experience in
transactions similar to the Merger and is familiar with Hornbeck and its
business. As part of its investment banking business, Simmons is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes.

     Pursuant to an engagement letter dated as of November 16, 1995, a fee of
0.9% of the aggregate market value of all shares of Hornbeck Common Stock
outstanding at the Effective Time (as defined below) will be payable to
Simmons upon consummation of the Merger for its services as financial advisor
to Hornbeck in connection with the Merger. Hornbeck has also agreed to
reimburse Simmons for its reasonable out-of-pocket expenses, including the
fees and expenses of its legal counsel, and to indemnify Simmons against
certain liabilities, including certain liabilities under the federal
securities laws, related to or arising out of its engagement as financial
advisor or its role in connection therewith.

     Simmons has represented Hornbeck in several acquisitions in the past and
has recently been serving on a retainer basis in seeking out and evaluating
possible businesses to acquire. Simmons has

                                      23
 <PAGE>


in the past acted on two occasions as co-manager of an underwriting syndicate
in connection with a public securities offering of Tidewater Common Stock
involving a selling stockholder. For this investment banking work with
Hornbeck and Tidewater, Simmons has received customary compensation. Since
January 1, 1994 Hornbeck has paid Simmons an aggregate amount of approximately
$550,000 for services rendered to Hornbeck. Simmons and its partners own
approximately 122,000 shares of Hornbeck Common Stock. In addition, in the
ordinary course of business, Simmons may actively trade the securities of
Hornbeck and Tidewater for its own account and for the accounts of customers
and, accordingly, may at any time hold a long or short position in such
securities.

     Mr. L.E. Simmons, a director of Hornbeck, was an officer and director of
Simmons until September 1993 and continues to own approximately three percent
of the outstanding common stock of Simmons. Mr. Matthew R. Simmons, brother of
Mr. L.E. Simmons, is the president and principal shareholder of Simmons.

EFFECTIVE TIME OF THE MERGER

     The Merger will become effective at the time (the "Effective Time") and
on the date (the "Effective Date") the Certificate of Merger is filed with the
Secretary of State of Delaware. Unless Tidewater and Hornbeck otherwise agree,
the Merger will be consummated as soon as practicable following receipt of
Hornbeck stockholder and necessary regulatory approvals and satisfaction or
waiver of the other conditions to the Merger. It is currently expected that
the Merger will become effective as soon as practicable following the Special
Meeting. See " -- Hart-Scott-Rodino Clearance" and " -- Other Conditions of
the Merger."

HART-SCOTT-RODINO CLEARANCE
   
     The obligations of Hornbeck and Tidewater to consummate the Merger are
subject to the expiration or termination of the requisite waiting periods
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the "HSR Act"). In addition, it is a condition to Tidewater's obligation to
consummate the Merger that such expiration or earlier termination be
accomplished without the imposition of any condition on Tidewater or Hornbeck
that would require the divestiture by either Hornbeck or Tidewater of any
asset of either party or that would otherwise have a material adverse effect
on Tidewater or Hornbeck. Under the HSR Act and the rules promulgated
thereunder by the Federal Trade Commission (the "FTC"), the Merger may not be
consummated until notifications have been given and certain information has
been furnished to the FTC and the Antitrust Division of the Department of
Justice (the "DOJ") and specific waiting period requirements have been
satisfied. Tidewater and Hornbeck each made the required initial filings under
the HSR Act on January 2, 1996 regarding the Merger. Under the HSR Act, the
required waiting periods are 30 days after the date of the filings, and 20 days
after the receipt of any additional information requested by the FTC or the DOJ.
The waiting period expired on February 1, 1996, without any further request for
additional information. As a practical matter, however, as discussed below, the
DOJ has the right to seek to enjoin the Merger at any time before its
consummation.
    
     Before the consummation of the Merger, the DOJ or the FTC could take such
action under the antitrust laws as it deems necessary or desirable and in the
public interest, including seeking to enjoin the consummation of the Merger.
Additionally, the DOJ or the FTC could, in connection with its review under
the HSR Act or at any time following consummation of the Merger, seek the
divestiture of substantial assets of Tidewater or Hornbeck. At any time before
or after the consummation of the Merger, and notwithstanding that the HSR Act
waiting period has expired, any state could take such action under the
antitrust laws as it deems necessary or desirable in the public interest. Such
action could include seeking to enjoin the consummation of the Merger or
seeking divestiture of Hornbeck or businesses of Tidewater or Hornbeck.
Private parties may also seek to take legal action under the antitrust laws
under certain circumstances.

     Based on information available to them, Tidewater and Hornbeck believe
that the Merger can be effected without the divestiture of assets or the
imposition of any other material condition on Tidewater or Hornbeck. There can
be no assurance, however, that a challenge to the consummation of the Merger

                                      24
 <PAGE>


on antitrust grounds will not be made or that, if such a challenge were made,
Tidewater and Hornbeck would prevail.

OTHER CONDITIONS TO THE MERGER
   
     In addition to Hornbeck stockholder and regulatory approval, the respective
obligations of Tidewater and Hornbeck to consummate the Merger are subject to
the satisfaction of certain conditions, including the following: (i) the
representations and warranties of Tidewater, Newco and Hornbeck contained in the
Merger Agreement being true and correct in all material respects as of the date
of the closing of the Merger, and the covenants of each of the parties to the
Merger Agreement having been duly performed in all material respects or waived;
(ii) the shares of Tidewater Common Stock to be issued pursuant to the Merger
Agreement having been approved for listing on the New York Stock Exchange and
the Pacific Stock Exchange, subject to official notice of issuance; (iii) the
receipt by each of Tidewater and Hornbeck of customary legal opinions,
certificates, covenants, consents, approvals and reports from the other parties
and from third parties, as applicable; (iv) the absence of any event or
circumstance from the date of the respective parties' latest balance sheet to
the date of the closing of the Merger resulting in a Material Adverse Effect (as
defined below) with respect to Hornbeck or Tidewater; (v) the receipt by each of
Tidewater and Hornbeck, immediately before the date of closing of the Merger, of
confirmation of the letters from KPMG Peat Marwick LLP stating that Tidewater is
eligible to be a party to a merger accounted for as a pooling of interests and
that they are not aware of any matters that would preclude the use of
pooling-of-interests accounting in connection with the Merger and from Price
Waterhouse LLP stating that as a result of specified procedures no matters have
come to their attention that would preclude Tidewater from accounting for the
business combination as a pooling of interests; (vi) the filing by Hornbeck with
the Commission of its annual report on Form 10-K for the fiscal year ending
December 31, 1995; (vii) the execution and delivery by Tidewater of a Consulting
Agreement providing for certain consulting services to be performed by Larry D.
Hornbeck; (viii) the Tidewater Board having taken action to appoint Larry D.
Hornbeck to the Tidewater Board effective on the second day following the
Effective Date; (ix) the receipt by Tidewater and Hornbeck, immediately prior to
the date of closing of the Merger, of confirmation of the tax opinions that each
received in connection with the execution of the Merger Agreement; and (x) the
absence of any pending or threatened suit, action or proceeding seeking to
restrain, prevent or change the transactions contemplated in the Merger
Agreement. As defined in the Merger Agreement, a "Material Adverse Effect" with
respect to either party means a material adverse effect on the financial
condition, results of operations, business or prospects of such party and its
20% or more-owned subsidiaries, taken as a whole, provided that, with respect
only to acts, events or occurrences that result, or that are reasonably likely
to result, individually or in the aggregate, in a quantifiable loss, cost or
expense (a "Quantifiable Loss"): (i) with respect to Hornbeck, a Quantifiable
Loss that does not exceed $6 million and (ii) with respect to Tidewater, a
Quantifiable Loss that does not exceed $35 million, will not be deemed to
constitute a Material Adverse Effect, but a Quantifiable Loss that does exceed
$6 million (with respect to Hornbeck) or $35 million (with respect to Tidewater)
will be deemed to constitute a Material Adverse Effect. A general economic
decline or a decline experienced by the offshore marine service industry,
generally, will not constitute a Material Adverse Effect with respect to either
party. The Merger Agreement also provides that no party is precluded from
asserting that acts, events or occurrences, the effects or reasonably likely
effects of which are not susceptible of being measured or reduced to a
Quantifiable Loss, have caused or resulted in or are likely to cause or result
in a Material Adverse Effect.
    
     No assurance can be given as to when all of the conditions to the Merger
can or will be satisfied or waived by the party permitted to do so, but
Tidewater and Hornbeck anticipate that such conditions will be satisfied as
soon as practicable following the Special Meeting.

                                      25
 <PAGE>


INTERESTS OF CERTAIN PERSONS IN THE MERGER

     APPOINTMENT TO TIDEWATER BOARD; CONSULTING AGREEMENT.  Effective on the
second day following the Effective Date, Larry D. Hornbeck, Chairman of the
Board, President and Chief Executive Officer of Hornbeck, will be appointed to
the class of the Tidewater Board with a term expiring at the annual meeting of
Tidewater's stockholders that next follows the Effective Date. In addition, as
a condition to the consummation of the Merger, Tidewater and Mr. Hornbeck will
execute a two-year consulting agreement which provides for Mr. Hornbeck to
render consulting and advisory services to Tidewater in return for payments
aggregating $350,000 and for Mr. Hornbeck to be recommended for reelection to
the Tidewater Board for a full three-year term at the next annual meeting of
Tidewater's stockholders. Also, under the terms of such consulting agreement,
Mr. Hornbeck will receive certain health insurance benefits, indemnification
with respect to activities undertaken in connection with services rendered
thereunder and an assignment of all right, title and interest in and to the
Hornbeck name and logo.
   
     TREATMENT OF HORNBECK STOCK OPTIONS, INCENTIVE AWARDS AND CHANGE IN
CONTROL AGREEMENTS.  At the time of execution of the Merger Agreement, there
were approximately 317,654 unissued shares of Hornbeck Common Stock subject to
unexercised stock options that were previously granted to officers and
employees of Hornbeck under its 1989 and 1993 Employee Incentive Plans. Under
the terms of the agreements pursuant to which such options were granted, any
options not previously vested that were granted under the 1989 Employee
Incentive Plan became fully vested and exercisable upon approval of the Merger
by the Hornbeck Board and any options not previously vested that were granted
under the 1993 Employee Incentive Plan will become fully vested and
exercisable upon consummation of the Merger. Holders of any options that are
not exercised for Hornbeck Common Stock by the Effective Time will have the
right, upon exercise of such options in accordance with their terms, to
acquire that number of shares of Tidewater Common Stock that the holder of
such unexercised options would have been entitled to receive upon consummation
of the Merger if such holder had exercised such options for shares of Hornbeck
Common Stock prior to or coincident with the Merger. Tidewater has agreed to
use its reasonable best efforts to cause a registration statement on Form S-8 to
be filed covering the shares of Tidewater Common Stock to be issued upon the
exercise of such options following the Effective Time or shall provide the
holders of such options with piggyback registration rights for such shares.

     Pursuant to the Merger Agreement, Hornbeck may make cash payments of up to
$350,000 in the aggregate (the "1995 Incentive Cash Payments") and issue an
aggregate of up to 19,310 shares of restricted Hornbeck Common Stock to its
directors, officers and employees as semi-annual director fees and incentive
payments for performance during 1995. If the Effective Date has not occurred by
April 30, 1996, Hornbeck may make additional cash payments to its officers and
employees as incentive payments for 1996 performance through the Effective Date
in amounts to be pro rated and based on the total 1995 Incentive Cash Payments.
The Compensation Committee of the Hornbeck Board has not yet determined the
amount or the allocation of the 1995 Incentive Cash Payments or the restricted
shares of Hornbeck Common Stock among Hornbeck officers and employees.
    
     Four executive officers of Hornbeck entered into change in control
agreements with Hornbeck in June 1995. If the Merger is consummated, and
subject to the arrangements described in the following paragraph, each such
officer will become entitled to a lump sum payment and certain continuing
benefits, including certain insurance coverage for a period of two years, as
provided in such officer's agreement, if such officer is terminated without
cause or terminates his employment for good reason as set forth in such
agreement within 24 months after the Effective Date. The aggregate amount of
the lump sum payments which such officers would become entitled to receive is
estimated to be approximately $2,872,000, of which $1,386,000 would be payable
to Larry D. Hornbeck and the remainder would be payable to the other three
executive officers with change in control agreements. The change in control
agreements further provide for a cashout of all unexercised options granted
more than six months prior to such officer's termination, but it is the
present intention of such executive officers to exercise all options prior to
or coincident with the Effective Time.

                                      26
<PAGE>
   
     Pursuant to agreements entered into on December 28, 1995, Hornbeck made
advance cash payments on such date in the aggregate amount of approximately
$2,500,000 to three of the four Hornbeck executive officers in connection with
the change in control agreements referred to above. Under the December 28
agreements, in order to minimize certain income tax costs to Hornbeck and such
officers, Hornbeck made lump sum cash advance payments on December 29 of 99% of
the amount to which Larry D. Hornbeck would have otherwise been entitled, and
90% of the amount to which the other two executive officers would have otherwise
been entitled, under such change in control agreements if the Merger were
consummated and certain other conditions set forth in such change in control
agreements were satisfied. If the Merger is consummated, each executive officer
will be paid the remaining cash payment due him under his change in control
agreement and will receive other benefits to the extent provided in such change
in control agreement. If the Merger is not consummated, each of the three
executive officers has agreed to remit to Hornbeck an aggregate of (i) cash in
an amount equal to 58.95% of the amount received by such executive officer in
1995, payable within five days of such event and (ii) an amount equal to any tax
benefit received because of such reimbursement, payable subsequently. If the
foregoing advance payments had not been made in 1995 by Hornbeck, then a
substantial portion of amounts paid to such individuals under their change in
control agreements may have been characterized as payments deemed not deductible
for federal income tax purposes. Neither these payments nor any tax gross up
payments made by Hornbeck under the change in control agreements would then be
deductible for income tax purposes by Hornbeck.
    
     SEVERANCE AND EMPLOYEE BENEFITS.  Hornbeck has agreed to comply with, and
Tidewater has agreed to honor, the terms of the severance policy adopted by
the Hornbeck Board for Hornbeck's employees having six or more months of
service who are not parties to the change in control agreements. The severance
policy provides, among other things, that each terminated employee of Hornbeck
will receive a termination payment based on the length of such employee's term
of service, but in no case to be less than twelve nor more than twenty-six
weeks of pay at such employee's current salary, and for continuation of health
insurance for such employee at no additional cost to such employee for twelve
weeks following termination, provided such employee elects and remains
eligible for COBRA coverage.

     Tidewater has agreed that following consummation of the Merger, it will
offer to all persons who were employees of Hornbeck or its subsidiaries and
who become employees of Tidewater following the Merger, the same employee
benefits as are offered by Tidewater to its own employees, subject to certain
limitations.
   
     CERTAIN INDEMNIFICATION COVENANTS.  The Merger Agreement provides that
Tidewater will indemnify and hold harmless, and will cause the surviving
corporation in the Merger to honor its separate indemnification obligations to,
each person who was an officer or director of Hornbeck, or of any of its
subsidiaries or any member of the North Sea Group who were serving at the
request of Hornbeck on December 21, 1995, or who previously served as such at
any time since January 1, 1993, from and against all damages, liabilities,
judgments and claims based upon or arising out of such person's service in such
capacity to the same extent as he or she would have been indemnified under the
Restated Certificate of Incorporation or Restated Bylaws of Hornbeck as they
were in effect on the date the Merger Agreement was executed. With certain
exceptions the aggregate amount of indemnification payments required to be made
under the Merger Agreement by Tidewater and/or the surviving corporation to such
persons is limited to $50 million. Tidewater has also agreed to pay the
insurance premiums required for any extension of Hornbeck's director's and
officer's insurance policy following the Effective Date for a period of six
years or to provide comparable coverage under a Tidewater policy.
    
RESALES OF TIDEWATER COMMON STOCK

     The shares of Tidewater Common Stock to be issued to the holders of
Hornbeck Common Stock pursuant to the Merger Agreement are being registered
under the Securities Act pursuant to a Registration Statement on Form S-4, of
which this Proxy Statement/Prospectus is a part. Holders of the Hornbeck
Common Stock who are affiliates of Hornbeck will not, however, be able to
resell the Tidewater Common Stock received by them in the Merger unless the
Tidewater Common Stock is registered for resale under the Securities Act, is
sold in compliance with Rule 145 under the Securities Act or is sold in
compliance with another exemption from the registration requirements of the
Securities Act.

                                      27
 <PAGE>


     Pursuant to Rule 145 under the Securities Act, the sale of Tidewater
Common Stock held by former affiliates of Hornbeck will be subject to certain
restrictions. Such persons may sell Tidewater Common Stock under Rule 145 only
if (i) Tidewater has filed all reports required to be filed by Section 13 or
15(d) of the Exchange Act during the preceding twelve months, (ii) such
Tidewater Common Stock is sold in a "broker's transaction," which is defined
in Rule 144 under the Securities Act as a sale in which (a) the seller does
not solicit or arrange for orders to buy the securities, (b) the seller does
not make any payment other than to the broker, (c) the broker does no more
than execute the order and receive a normal commission and (d) the broker does
not solicit customer orders to buy the securities, and (iii) such sale and all
other sales made by such person within the preceding three months do not
exceed the greater of (x) one percent of the outstanding shares of Tidewater
Common Stock or (y) the average weekly trading volume of Tidewater Common
Stock on the New York Stock Exchange during the four-week period preceding the
sale. Any affiliate of Hornbeck who is not an affiliate of Tidewater after the
Merger may sell Tidewater Common Stock without restriction following the
second anniversary of the Effective Date.

     Holders of Hornbeck options who do not exercise such options at or before
the Effective Date will, upon subsequent exercise of such option, receive
unregistered Tidewater Common Stock and will be unable to sell such Tidewater
Common Stock unless and until an exemption from the registration requirements
of the Securities Act is available with respect to such Tidewater Common Stock
or such Tidewater Common Stock has been registered pursuant to the Securities
Act. Tidewater has agreed to use its reasonable best efforts to cause a
registration statement on Form S-8 to be filed covering such Tidewater Common
Stock to be issued upon the exercise of such options following the closing of
the Merger or to provide piggyback registration rights to the holders of
Tidewater Common Stock issued in connection with the exercise of such options.

EXCHANGE OF CERTIFICATES

     At the Effective Time, each Hornbeck stockholder will cease to have any
rights as a stockholder of Hornbeck and his or her sole rights will pertain to
the shares of Tidewater Common Stock into which such holder's shares of
Hornbeck Common Stock shall have been converted pursuant to the Merger, except
for the right to receive cash for any fractional shares.

     Upon consummation of the Merger, a letter of transmittal, including a
citizenship certificate and instructions for the exchange of certificates
representing shares of Hornbeck Common Stock for certificates representing
Tidewater Common Stock, will be mailed to each person who was a stockholder of
record of Hornbeck at the Effective Time. STOCKHOLDERS ARE REQUESTED NOT TO
SEND IN THEIR HORNBECK COMMON STOCK CERTIFICATES UNTIL THEY HAVE RECEIVED A
LETTER OF TRANSMITTAL AND FURTHER WRITTEN INSTRUCTIONS. Immediately following
receipt from a holder of Hornbeck Common Stock of the letter of transmittal
completed in accordance with its instructions, including the completed
certificate of citizenship and the certificates representing shares of
Hornbeck Common Stock, Tidewater will deliver a certificate representing that
number of whole shares of Tidewater Common Stock into which such holder's
shares of Hornbeck Common Stock have been converted pursuant to the Merger and
a check in payment for any fractional share of Tidewater Common Stock to which
such holder may be entitled.

     After the Effective Date and until surrendered, certificates representing
Hornbeck Common Stock will be deemed for all purposes, other than the payment
of dividends or other distributions, if any, in respect of Tidewater Common
Stock, to represent the number of whole shares of Tidewater Common Stock into
which such shares of Hornbeck Common Stock have been converted. Tidewater, at
its option, may decline to pay former stockholders of Hornbeck who become
holders of Tidewater Common Stock pursuant to the Merger any dividends or
other distributions that may have become payable to holders of record of
Tidewater Common Stock following the Effective Date until they have
surrendered their certificates evidencing ownership of shares of Hornbeck
Common Stock along with a properly completed letter of transmittal and
citizenship certificate.

                                      28

     Hornbeck stockholders who cannot locate their certificates are urged to
contact promptly the Corporate Secretary, Hornbeck Offshore Services, Inc.,
7707 Harborside Drive, Galveston, Texas, 77554, telephone number (409)
744-9500. A new certificate will be issued to replace the lost certificate(s)
only upon execution by the stockholder of an affidavit certifying that his or
her certificate(s) cannot be located and an agreement to indemnify Hornbeck
and Tidewater and their transfer agents and registrars against any claim that
may be made against Hornbeck or Tidewater by the owner of the certificate(s)
alleged to have been lost or destroyed. Hornbeck or Tidewater may also require
the stockholder to post a bond in such sum as is sufficient to support the
stockholder's agreement to indemnify Hornbeck and Tidewater.

CONDUCT OF BUSINESS BY HORNBECK AND TIDEWATER PENDING THE MERGER

     The Merger Agreement provides that until the Effective Time each of
Tidewater and Hornbeck will use its reasonable best efforts to preserve the
goodwill of suppliers, customers, and others having business relations with it
and to do nothing knowingly to impair its ability to keep and preserve its
business as it existed on the date of the Merger Agreement.

     In addition, the Merger Agreement provides that neither Tidewater nor
Hornbeck will, without the prior written consent of the other party, (i)
declare or pay any dividend or other distribution with respect to its
respective common stock or issue, deliver or sell any additional shares of its
capital stock or any securities convertible into or exchangeable for its
capital stock except in accordance with previous practice or as required under
existing agreements; (ii) amend its certificate of incorporation or bylaws or
adopt or amend any resolution or agreement concerning indemnification of its
directors, officers, employees or agents; (iii) pledge or otherwise encumber
any shares of its capital stock or other voting securities; (iv) breach any

Agreement to become untrue; (v) violate any applicable law, statute, rule,
governmental regulation or order that would have a Material Adverse Effect on
such party; (vi) fail to maintain its books, accounts and records in the usual
manner; (vii) fail to pay, or provide for the payment of, all taxes, interest
payments and penalties due and payable; (viii) alter its prior practice with
respect to tax elections or settle or compromise any income tax liability for
an amount materially in excess of the liability therefor; (ix) take any action
that would prevent the accounting for the business combination to be effected
by the Merger as a pooling of interests; or (x) authorize, agree to do or
commit to do any of the foregoing actions.

CONDUCT OF BUSINESS BY HORNBECK PENDING THE MERGER

     The Merger Agreement provides that until the Effective Time, in addition
to the covenants set forth above, Hornbeck shall use its best efforts to
preserve the possession and control of all of its assets other than those
permitted to be disposed of pursuant to the terms of the Merger Agreement,
shall conduct its business only in the ordinary course and, except as
otherwise provided in the Merger Agreement, shall not, without the prior
written consent of Tidewater: (i) enter into or modify any employment,
severance or similar agreement or arrangement with any director or employee,
or grant any increase in the rate of wages, salaries, bonuses or other
compensation or benefits of any executive officer or other employee; (ii)
enter into any new line of business; (iii) acquire or agree to acquire any
business or any assets that are material, individually or in the aggregate, to
Hornbeck and its subsidiaries taken as a whole, except for the right of
Hornbeck to exercise options to acquire additional equity interests in
Ravensworth in accordance with the terms and conditions contained in the
Merger Agreement; (iv) sell or otherwise dispose of or encumber any of its
properties or assets; (v) incur any indebtedness for borrowed money or
guarantee any such indebtedness of another person or otherwise enter into any
arrangement having similar economic effect; (vi) make or agree to make any new
capital expenditures from available cash (excluding the proceeds of
borrowings) other than those made in the ordinary course of business and
consistent with past practices; (vii) approve the declaration or payment of
any dividend or distribution by Ravensworth or Seaboard; (viii) except in the
ordinary course of business, permit any liens on its assets, or forgive any
material indebtedness or waive any rights with

                                      29
 <PAGE>


respect to any material noncurrent liability; (ix) acquire another business or
entity or sell or otherwise dispose of a material part of its assets, except
in the ordinary course of business consistent with past practices; (x) permit
any employee or former employee, officer or director to become entitled to
receive any award under any discretionary or other bonus plan; or (xi)
authorize, agree to do or commit to do any of, the foregoing actions.
Moreover, Hornbeck has agreed that it will consult with Tidewater with respect
to any action of the type described above proposed to be taken by a member of
the North Sea Group.

     Hornbeck has options to acquire up to the remaining 50.1% equity interest
in Ravensworth (the "Ravensworth Options") as well as options to acquire the
remaining 50.1% equity interests in Seaboard and North Sea Manager (as defined
below). See "Business of Hornbeck -- North Sea Group." The Merger Agreement
provides that until February 29, 1996, Hornbeck will not exercise, modify or
cancel either of the Ravensworth Options without Tidewater's prior consent and
that after February 29, 1996 until the Effective Date, Hornbeck may exercise,
modify or cancel such Ravensworth Options after consulting with Tidewater but
will not issue Hornbeck Common Stock as consideration for the exercise of such
Ravensworth Options without Tidewater's prior consent.

NO SOLICITATION OF TRANSACTIONS; TERMINATION FEE

     The Merger Agreement prohibits Hornbeck and its subsidiaries and the
North Sea Group from, directly or indirectly, through any officer, director,
employee, representative or agent, soliciting or encouraging the initiation of
any inquiries, proposals or offers regarding any acquisition, merger, takeover
bid, sale of all or substantially all of the assets of or sales of shares of
capital stock of Hornbeck or similar transactions involving Hornbeck.

     If the Hornbeck Board, after duly considering advice of outside counsel
and financial advisors, determines in good faith that it is consistent with
its fiduciary responsibilities to approve or recommend (and in connection
therewith withdraw or modify its approval or recommendation of the Merger
Agreement and the transactions contemplated thereby) a Superior Proposal (as
defined below), then, notwithstanding any such approval or recommendation (i)
Hornbeck may not enter into any agreement with respect to the Superior
Proposal and (ii) any other obligation of Hornbeck under the Merger Agreement
shall not be affected unless the Merger Agreement is terminated in accordance
with its terms before or simultaneously with the grant of such approval or the
making of such recommendation and Hornbeck, within three business days
following such termination, pays Tidewater the Termination Fee of $6,000,000
in cash. A "Superior Proposal" is defined to mean a bona fide proposal made by
a third party to acquire Hornbeck pursuant to a tender or exchange offer, a
merger, a sale of all or substantially all of its assets or other proposal
that the Hornbeck Board determines in its good faith judgment to be more
favorable to the holders of Hornbeck Common Stock than the transactions
contemplated by the Merger Agreement, after considering advice of its
professional advisors. In making a determination of whether a Superior
Proposal is more favorable, the Hornbeck Board is required pursuant to the
Merger Agreement to consider not only the price offered by the third party as
compared to the total consideration set forth in the Merger Agreement, but
also to compare the market liquidity of the Tidewater Common Stock to the
liquidity of the consideration offered by the third party, to compare the tax
consequences of the Merger to the tax consequences of the transaction proposed
by the third party, to determine whether the transaction proposed by the third
party has any financing or other conditions or contingencies, and to make any
other meaningful comparison of the relative benefits offered to the Hornbeck
stockholders by the Merger as compared to the transaction proposed by the
third party.

AMENDMENT; WAIVER; TERMINATION

     The Merger Agreement may be amended at any time before or after its
approval by the stockholders of Hornbeck by written agreement of Tidewater and
Hornbeck, except that no amendment may be made after Hornbeck stockholder
approval that by law would require further stockholder approval unless such
further stockholder approval is obtained.

                                      30
 <PAGE>


     The Merger Agreement provides that either party may (i) extend the time
for the performance of any of the obligations or other acts of the other
parties, (ii) waive any inaccuracies in the representations and warranties
contained in the Merger Agreement or in any document delivered pursuant to the
Merger Agreement or (iii) waive compliance with any of the agreements or
conditions contained in the Merger Agreement other than the satisfaction of
all requirements prescribed by law for consummation of the Merger.

     The Merger Agreement may be terminated at any time before the Effective
Time (i) by the mutual consent of the Tidewater Board and Hornbeck Board or
(ii) by the board of directors of either party if (a) there has been a
material breach by the other party of any representation, warranty or covenant
contained in the Merger Agreement which has not been cured within fifteen days
after written notice of such breach is given to the breaching party, (b) the
required Hornbeck stockholder approval shall not have been obtained at the
Special Meeting, (c) all conditions to closing have not been met or waived or
any condition is incapable of being met and has not been waived by each party
in favor of which such condition inures, or the Merger has not been
consummated, by November 20, 1996, unless the party seeking to terminate the
Merger Agreement is, at such time, in willful material violation of any of its
representations, warranties or covenants contained in the Merger Agreement,
(d) any governmental entity shall have issued an order, decree or ruling or
taken any other action permanently enjoining, restraining or otherwise
prohibiting the Merger and such order, decree, ruling or other action shall
have become final and nonappealable or (e) the Conversion Ratio would be less
than .60 or greater than .74. Also, Hornbeck may terminate the Merger if the
Hornbeck Board withdraws its recommendation of the Merger to the holders of
Hornbeck Common Stock in connection with its approval or recommendation to the
holders of Hornbeck Common Stock of a Superior Proposal and pays the
Termination Fee to Tidewater. See " -- No Solicitation of Transactions;
Termination Fee."

FEES AND EXPENSES

     The Merger Agreement provides that whether or not the Merger is
consummated, all fees and expenses incurred in connection with the Merger
shall be paid by the party incurring them.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

     Tidewater has received an opinion of its counsel, Jones, Walker,
Waechter, Poitevent, Carrere & Denegre, L.L.P. and Hornbeck has received an
opinion of its independent accountants, Price Waterhouse LLP, to the effect
that for federal income tax purposes (i) the Merger will constitute a tax-free
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code and (ii) Tidewater, Hornbeck and Newco will each be a party to the
reorganization within the meaning of Section 368(b) of the Internal Revenue
Code. These opinions will be confirmed by such counsel and accountants
immediately before the Effective Time.

     Assuming the above opinions are correct, (i) no gain or loss will be
recognized by Tidewater or its stockholders as a result of the Merger, (ii) no
gain or loss will be recognized by stockholders of Hornbeck who receive
Tidewater Common Stock in the Merger in exchange for their shares of Hornbeck
Common Stock except for any gain realized upon the receipt of cash by the
holders of Hornbeck Common Stock in lieu of receiving fractional shares of
Tidewater Common Stock, (iii) no gain or loss will be recognized by Hornbeck
as a result of the Merger, (iv) the basis of the shares of Tidewater Common
Stock to be received by the holders of Hornbeck Common Stock in the Merger
will be the same as the basis of the shares of Hornbeck Common Stock
surrendered in exchange therefor, (v) the holding period of the shares of
Tidewater Common Stock to be received by the holders of Hornbeck Common Stock
in the Merger will include the holding period of the respective shares of
Hornbeck Common Stock exchanged therefor, provided that the shares are held as
capital assets in the hands of the holders of the Hornbeck Common Stock at the
Effective Time, and (vi) the payment of cash to holders of Hornbeck Common
Stock in lieu of fractional shares of Tidewater Common Stock will be treated
as if the fractional shares were distributed as part of the exchange and then
redeemed by Tidewater.

                                      31
 <PAGE>


     An opinion of counsel or independent accountants is not binding on the
Internal Revenue Service or the courts. Therefore, there can be no assurance
that the Merger will constitute a tax-free reorganization or that any of the
other favorable tax treatments listed above will be available to the holders
of Hornbeck Common Stock.

     Because of the complexity of the tax laws and because the tax
consequences to any particular stockholder may be affected by matters not
discussed herein, it is recommended that each holder of Hornbeck Common Stock
consult a tax advisor concerning the applicable federal, state and local
income tax consequences of the Merger.

ACCOUNTING TREATMENT

     Tidewater has received an opinion of KPMG Peat Marwick LLP, dated as of a
date within three business days of the date the Merger Agreement was signed,
to the effect that they are not aware of any matters that would preclude the
Merger from qualifying as a pooling of interests under the requirements of
Opinion No. 16 of the Accounting Principles Board of the American Institute of
Certified Public Accountants and the published rules and regulations of the
Commission for accounting and financial reporting purposes, and Hornbeck has
received a letter from Price Waterhouse LLP, dated as of a date within three
days of the date the Merger Agreement was signed, that as a result of
specified procedures, no matters came to their attention that would preclude
Tidewater from accounting for the business combination as a pooling of
interests under such requirements. It is a condition to each party's
obligation to consummate the Merger that the opinion and letter, respectively,
be confirmed by such accounting firms immediately before the Effective Time.
Under the pooling-of-interests method of accounting, after certain adjustments
necessary to conform the basis of presentation of the Tidewater and Hornbeck
information, the recorded assets and liabilities of Tidewater and Hornbeck
will be carried forward to Tidewater's consolidated financial statements at
their recorded amounts, the consolidated earnings of Tidewater will include
earnings of Tidewater and Hornbeck for the entire fiscal year in which the
Merger occurs and the reported earnings of Tidewater and Hornbeck for prior
periods will be combined and restated as consolidated earnings of Tidewater.

APPRAISAL RIGHTS

     Under the DGCL, appraisal rights are not available to Hornbeck
stockholders with respect to the Merger Agreement.

                          BUSINESS OF THE COMPANIES
INTRODUCTION

     Both Tidewater and Hornbeck provide offshore supply vessels and marine
support services to the oil and gas industry. However, Hornbeck's operations
are concentrated in the Gulf of Mexico, with the exception of its safety
standby operations in the North Sea, while Tidewater's marine operations are
conducted worldwide. Additionally, Tidewater offers, through its compression
division, natural gas and air compression equipment and services to the oil
and gas industry, primarily in the United States.

BUSINESS OF TIDEWATER

     Tidewater serves the international oil and gas industry through its two
principal divisions: Tidewater Marine and Tidewater Compression. Currently,
Tidewater Marine and Tidewater Compression account for approximately 80% and
20%, respectively, of Tidewater's revenues. The principal executive offices of
Tidewater are located at 1440 Canal Street, New Orleans, Louisiana 70112
(Telephone No. (504) 568-1010).

     TIDEWATER MARINE.  Through its Tidewater Marine division, Tidewater is
the world's largest provider of offshore supply vessels and marine support
services. With a fleet of approximately 570 vessels, Tidewater Marine
operates, and has a leading market share, in most of the world's significant
offshore oil and gas exploration and production markets. Tidewater Marine
provides services supporting all phases of offshore exploration, development
and production, including: towing and anchor handling of mobile drilling rigs
and equipment; transporting supplies and personnel to sustain drilling,
work-over and production activities; and supporting pipelaying and other
offshore construction activities.

     Tidewater's fleet is deployed in the major offshore oil and gas areas of
the world. The principal areas of Tidewater's operations include the Gulf of
Mexico, offshore Australia, Brazil, Egypt, India, Indonesia, Malaysia, Mexico,
Trinidad, Venezuela, various countries of West Africa and the North Sea and
the Persian Gulf. Tidewater conducts its operations through wholly-owned
subsidiaries and joint ventures.

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

     Tidewater's other classes of vessels include crew and utility vessels
that are chartered to customers for use principally in transporting supplies
and personnel from shore bases to offshore drilling rigs, platforms and other
installations, and offshore tugs that tow floating drilling rigs, dock
tankers, tow barges, assist pipelaying and construction barges and are used in
a variety of other commercial towing operations, including towing barges
carrying a variety of bulk cargoes and containerized cargo.

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

     TIDEWATER COMPRESSION.  Tidewater Compression provides natural gas and
air compression equipment and services principally to the energy industry in
the United States. With a fleet of approximately 2,900 compressors, Tidewater
Compression operates the largest rental fleet of gas compressors in the United
States, which it rents to oil and gas producers and processors. The
compressors are used primarily to boost the pressure of natural gas from the
wellhead into gas gathering systems, into nearby gas processing plants or into
high pressure pipelines. Gas compression equipment and services offered by
Tidewater are also used in the production of coalbed methane and in enhanced
recovery projects such as fire-flooding, gas lift, or gas injection, with the
objective of

                                      33
 <PAGE>


increasing the amount of oil or condensate that can be recovered from a
reservoir. Customers often rent compressors rather than purchase them because
the required compressor horsepower and stage configuration can change several
times during the lifetime of a project. Tidewater primarily serves the natural
gas production market in the United States, although Tidewater is actively
seeking to establish itself in markets outside the United States.

     During fiscal 1995, Tidewater almost tripled the size of its gas
compression fleet through its acquisition of the natural gas compression
assets of Halliburton Company and one of its affiliated companies and Brazos
Gas Compressing Company, a subsidiary of Mitchell Energy & Development Corp.

BUSINESS OF HORNBECK

     GENERAL.  Hornbeck is engaged in the offshore marine services business,
serving the oil and gas industry primarily in the Gulf of Mexico through its
operation and management of a diversified fleet of 61 vessels, consisting of
supply, tug-supply, crew and specialty service vessels. Hornbeck currently
uses such vessels to provide a wide range of services, such as transporting
supplies necessary to sustain drilling, workover and production activities;
supporting offshore pipelaying and construction; and assisting geophysical
evaluation. Fifty-six of these vessels are owned, four are chartered and one
is managed by Hornbeck. Hornbeck operates the second largest fleet of supply
vessels both in the Gulf of Mexico and in the world. Hornbeck also has 49.9%
equity interests in Ravensworth and Seaboard, which have a combined total of
29 vessels, the largest safety standby fleet operating in the North Sea.
Founded in 1981, Hornbeck is headquartered in Galveston, Texas, and also
conducts its Gulf of Mexico operations from its office in Morgan City,
Louisiana. North Sea operations of Ravensworth and Seaboard are conducted from
offices in Douglas, Isle of Man, and Aberdeen, Scotland.

     Hornbeck's fleet has an average age of approximately 15 years. Hornbeck's
vessels support the entire range of the offshore exploration and development
business, including transporting supplies necessary to sustain drilling,
workover and production activities, supporting offshore pipelaying and
construction activities, and assisting geophysical evaluation.

     NORTH SEA GROUP.  On July 23, 1993, Hornbeck acquired 49.9% of the
outstanding capital stock of Ravensworth from Ravensworth Holdings Limited
("RHL"), the sole beneficial holder of the outstanding capital stock of
Ravensworth, together with options to acquire the remaining 50.1% outstanding
equity interest in Ravensworth. See "Hornbeck Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources" and see "The Merger -- Conduct of Business by Hornbeck
Pending the Merger" with respect to restrictions on the exercise of the
Ravensworth Options. Through its 49.9%-owned affiliate, Hornbeck owns all of
the outstanding capital stock of Seaboard Offshore Group Limited ("SOGL")
which owns six safety standby vessels in the North Sea. Hornbeck also
participated in the formation and holds 49.9% of the outstanding capital stock
of Hornbeck Offshore Limited (the "North Sea Manager") and owns the options to
purchase the remaining 50.1% equity interests in Seaboard and North Sea
Manager.

     Ravensworth and Seaboard, through their subsidiaries, are engaged in the
offshore marine services business primarily serving the oil and gas industry
in the North Sea by providing safety standby vessels. Under the United
Kingdom's Offshore Installations (Emergency Procedures) Regulations 1976 and
Code for the Assessment of the Suitability of Standby Vessels, as revised in
1991 (collectively, the "Safety Code"), existing manned platforms and offshore
drilling rigs are subject to offshore marine safety requirements and offshore
operations and operators are required to engage and maintain the availability
of safety standby vessels. The Safety Code requires that a vessel "standby" to
provide a means of rescuing platform or rig personnel in the event of an
emergency at such an offshore facility. Through the combined fleet of 29
vessels, 23 owned and six chartered (with related purchase rights and
obligations), Ravensworth and Seaboard provide such safety standby services,
generally pursuant to long-term charters.

     All of the Ravensworth vessels and all of the Seaboard vessels are
operated by the North Sea Manager. The crews and officers who work on the
vessels are employed by foreign subsidiaries of Ravensworth and Seaboard.

     The unaudited pro forma condensed combined statements of earnings set
forth below have been compiled from the following:

          (1)  Tidewater audited statements of earnings for each of the years
     in the three-year period ended March 31, 1995.

          (2)  Tidewater unaudited statements of earnings for the six months
     ended September 30, 1994 and 1995.

          (3)  Hornbeck audited statements of earnings for each of the years
     in the three-year period ended December 31, 1994.

          (4)  Hornbeck unaudited statements of earnings for the six months
     ended September 30, 1994 and 1995.

     Hornbeck's fiscal year end is December 31 and Tidewater's fiscal year end
is March 31. The March 31, 1993, 1994 and 1995 Tidewater statements of
earnings are combined with the Hornbeck statements of operations for the years
ended December 31, 1992, 1993 and 1994, respectively. The Unaudited Pro Forma
Condensed Combined Statements of Earnings for the six months ended September
30, 1994 and 1995 include results of each entity for the six months ended
September 30, 1994 and 1995. See Note (e) of "Notes to Tidewater Unaudited Pro
Forma Condensed Combined Financial Information" for the Hornbeck unaudited
statements of earnings for the six months ended September 30, 1994 and 1995.
Additionally, retained earnings of the combined entities were adjusted by
$433,000 as of the beginning of Tidewater's fiscal 1996 year to include the
unaudited net earnings of Hornbeck, including adjustments to conform
accounting policies to those of Tidewater, for the period from January 1, 1995
to March 31, 1995. During this period, Hornbeck's revenues were $12,671,000.

     The following unaudited pro forma condensed combined statements of
earnings give effect to the Merger under the pooling-of-interests accounting
method as if Tidewater and Hornbeck had been combined since inception.

NOTES TO TIDEWATER UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL
INFORMATION:

(a)   To conform accounting policies regarding certain drydocking costs which
      have been capitalized and amortized over periods of 24 to 36 months in
      Hornbeck's historical financial statements but are expensed as incurred
      by Tidewater. To conform Hornbeck's historical amounts to Tidewater's
      policy, other assets have been reduced at September 30, 1995 by
      $6,955,000. Marine equipment operating expenses have been increased by
      $1,223,000, $5,825,000 and $2,915,000 for the years ended March 31,
      1993, 1994 and 1995, respectively, and $2,435,000 and $4,505,000 for the
      six-month periods ended September 30, 1994 and 1995, respectively.
      Depreciation expense has been reduced by $1,252,000, $2,110,000 and
      $3,740,000 for the years ended March 31, 1993, 1994 and 1995,
      respectively, and $1,936,000 and $2,041,000 for the six-month periods
      ended September 30, 1994 and 1995, respectively.

(b)  To reflect the income tax expense effect of the pro-forma adjustments
     discussed in note (a) above, income tax expense has been increased
     (decreased) by $10,000, ($1,300,000) and $289,000 for the years ended
     March 31, 1993, 1994 and 1995, respectively, and ($175,000) and
     ($863,000) for the six-month periods ended September 30, 1994 and 1995,
     respectively. The deferred income tax liability account has been reduced
     at September 30, 1995 by $2,434,000 for the net effect of the adjustments
     described above.

(c)   To give effect to the issuance of 8,800,000 shares (assuming a
      Conversion Ratio of .667 shares and prior to giving effect to the exercise
      of 317,654 Hornbeck stock options) of Tidewater Common Stock in exchange
      for 13,240,000 shares of Hornbeck Stock. The excess of par value of the
      13,240,000 shares of Hornbeck Stock surrendered upon consummation of the
      Merger over par value of the 8,800,000 shares of Tidewater Common Stock
      issued upon consummation of the Merger is credited to additional paid-in
      capital.

(d)  The retained earnings adjustment of $4,521,000 reflects the combined
     effect of the adjustments referenced under notes (a) and (b).

                                           (NOTES CONTINUED ON FOLLOWING PAGE)

    TIDEWATER MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                              RESULTS OF OPERATIONS

     This discussion and analysis of financial condition and results of
operations of Tidewater should be read in conjunction with the consolidated
financial statements, the related disclosures and the selected financial data
of Tidewater included elsewhere herein.

                 SIX MONTHS ENDED SEPTEMBER 30, 1994 AND 1995

     Fiscal 1996 six-month net earnings rose significantly above prior year
levels due to better market conditions for offshore Tidewater Marine services
and a considerably larger Tidewater Compression rental fleet.

LIQUIDITY AND CAPITAL RESOURCES

     Fiscal 1996 six-month operating activities generated higher cash than
fiscal 1995's corresponding period. The increase is attributable to a
significantly larger natural gas compressor fleet and higher utilization and
day rates for the Tidewater Marine vessel fleet. Operating activities continue
to generate cash in excess of normal operating requirements. Anticipated
utilization levels for the Tidewater Marine vessel fleet and Tidewater
Compression rental fleet for the remainder of fiscal 1996 should maintain this
condition.

     Cash used in investing activities for the six-month period ended
September 30, 1995 was significantly lower than the amount for the
corresponding period of fiscal 1995. Investing activities for the six-month
period ended September 30, 1994 include the purchase of the assets of Brazos
Gas Compressing Company, a subsidiary of Mitchell Energy & Development
Corporation, for $35 million in cash on September 30, 1994. Excluding
acquisitions, additions to properties and equipment and proceeds from asset
sales determine the overall amount of cash used in investing activities. The
following tables compare these two items, by business segment, for the
six-month periods ended September 30, 1994 and 1995:

     Tidewater Marine additions for the current six-month period include the
$6.1 million purchase of five offshore tugs and a utility vessel previously
operated under long-term lease. Current economic conditions generally do not
favor the construction of Tidewater Marine vessels; therefore, future
expansion of the Tidewater Marine fleet will continue to come primarily from
existing industry supplies provided appropriate rates of return can be
achieved.

     Cash used in fiscal 1996 six-month financing activities was significantly
higher than fiscal 1995's six-month period because of $58 million of
prepayments on long-term debt borrowed in connection with the purchase of
Halliburton's natural gas compression assets on November 30, 1994. As of
September 30, 1995 existing long-term debt of $48 million was borrowed under
the revolving credit

facility of Tidewater's revolving credit and term loan agreement. Principal
payments on long-term debt for the six months ended September 30, 1994 include
the redemption of 7% convertible subordinated debentures for $46.0 million.
Continued dividend payments are subject to declaration by the Board of
Directors and are limited by Tidewater's revolving credit and term loan
agreement.

     Fiscal 1996 six-month consolidated revenues and pre-tax earnings rose
8.5% and 38.2%, respectively, above fiscal 1995's corresponding six-month
amounts. The increase in pre-tax earnings for the current six-month period is
because of higher Tidewater Marine and Tidewater Compression operating profits
partially offset by higher interest expense. Higher Tidewater Marine operating
profit is due to higher utilization and day rates for the vessel fleet, the
net positive effect of lower depreciation expense due to the increase in
vessel useful lives effective April 1, 1995, and lower general and
administrative expenses as a result of Tidewater's restructuring of worldwide
Tidewater Marine operations in fiscal 1995's fourth quarter. Fiscal 1995's
six-month Tidewater Marine operating profit also includes $1.7 million of
refunds received from the settlement of prior years' property tax disputes.
Higher Tidewater Compression operating profit and higher interest expense are
the result of the expansion of the natural gas compressor rental fleet and
associated debt borrowings during the second half of fiscal 1995.

     General and administrative expenses by type for the six-month periods
ended September 30, 1994 and 1995 are as follows:

TIDEWATER MARINE SEGMENT

     The Tidewater Marine segment 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 principally consist 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 dictated
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 Tidewater Marine segment and provide a breakdown of
Tidewater Marine operating profit for the six-month periods ended September
30, 1994 and 1995:

     Fiscal 1996 six-month operating margin was consistent with the prior year
six-month period as slightly higher utilization and higher average day rates
for the fleet were offset by higher repair and maintenance expense. The
increase in repair and maintenance is partially due to the increase in vessel
useful lives which became effective at the beginning of the current fiscal
year and had the effect of expensing drydocking costs, which under the old
vessel useful lives, would have been capitalized.

     Tidewater Marine fleet utilization is determined primarily by market
conditions and to a lesser extent by drydockings to satisfy safety and
inspection requirements. The following table compares day-based Tidewater
Marine fleet utilization percentages by vessel class and in total for the
six-month periods ended September 30, 1994 and 1995:

     Utilization presented reflects demand trends for offshore marine
services. Fiscal 1996 six-month fleet utilization rose slightly above fiscal
1995's six-month level as higher demand for towing supply/supply and
crew/utility marine services in foreign markets outweighed the drop in demand
for marine services provided by crew/utility vessels and offshore tugs in the
Gulf of Mexico due to uncertainties affecting the price of U.S. natural gas.

     Tidewater Marine vessel day rates are primarily determined by the demand
created through the level of offshore exploration, development and production
spending by energy exploration and production companies. Suitability of
equipment, the degree of service provided and the overall supply of marine
service vessels also influence vessel day rates. The following table provides
a comparison of average vessel day rates by class and in total for the
six-month periods ended September 30, 1994 and 1995:

     The domestic fleet consists of vessels operating in U.S. waters while the
foreign fleet consists of vessels operating outside U.S. waters.

     Higher average day rates in the current six-month period compared to the
prior year's corresponding six-month period is attributed to a more favorable

     The drop in the average number of vessels in the foreign-based vessel
fleet from 324 for the six-month period ended September 30, 1994 to 305 for
the six-month period ended September 30, 1995 is due to older vessels being
withdrawn from active service due to age and high repair and maintenance
costs. Vessels will continue to be withdrawn from active service as they
become uneconomical to operate.

TIDEWATER COMPRESSION SEGMENT

     The Tidewater Compression segment 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 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 fleet size and general
inflationary factors. Tidewater Compression segment operating profit is
primarily determined by operating margins from rental gas compression
operations. The following tables compare revenues,

     Higher revenues and operating margins for the six-month period ended
September 30, 1995 compared to the corresponding amounts for the same period
of fiscal 1995 are the result of the considerable expansion of the gas
compression rental fleet which occurred during the second half of fiscal 1995.
Fiscal 1996 six-month utilization fell below the level for the corresponding
period of fiscal 1995 due to a combination of the expansion of the rental
fleet noted above and to lower demand for compression services. The natural
gas compressor fleets which were purchased during fiscal 1995 historically
experienced lower levels of utilization than the original Tidewater fleet.
Lower demand for compression services in the current six-month period is the
result of lower U.S. natural gas prices.

     The Tidewater Compression segment also designs, fabricates and installs
engineered compressor systems and sells, primarily to its customers, related
parts and equipment. The following table compares revenues, costs of sales and
sales margins for equipment and parts sales for the six-month periods ended
September 30, 1994 and 1995:

presented are due to the timing of sales of engineered products. Fluctuations
in operating margin percentages are the result of

                                      48
<PAGE>
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.

     Gains from sales of assets have contributed nominally to segment profits
for the six-month periods ended September 30, 1995 and 1994.

CURRENCY FLUCTUATIONS AND INFLATION

     Because of its significant foreign operations, Tidewater is exposed to
currency fluctuations and exchange risks. To minimize the financial impact of
these items Tidewater 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 Tidewater's operating
costs. The major impact on operating costs is the level of offshore
exploration and development 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
Tidewater from the inflationary effects on operating costs.

ENVIRONMENTAL MATTERS

     During the ordinary course of business Tidewater's operations are subject
to a wide variety of environmental laws and regulations. Tidewater attempts to
comply with these laws and regulations in order to avoid costly accidents and
related environmental damage. Tidewater is currently involved in litigation
with the Environmental Protection Agency concerning the disposal of oilfield
wastes. In the opinion of management, the ultimate liability with respect to
the litigation will not have a material adverse effect on Tidewater's
financial position.

                           ------------------------

                  YEARS ENDED MARCH 31, 1993, 1994 AND 1995

     Fiscal 1995 pre-tax earnings rose approximately 17% principally due to
the significant expansion of Tidewater's natural gas compressor fleet and
higher gains from asset sales. Fiscal 1995 results also include certain
charges related to Tidewater's restructuring of its headquarters and worldwide
marine operations and increased reserves to cover possible losses due to the
potential insolvency of certain of Tidewater's insurers. Demand for
Tidewater's services weakened during fiscal 1995 as a result of lower U.S.
natural gas prices and the instability of the price of oil.

LIQUIDITY AND CAPITAL RESOURCES

     Fiscal 1995 operating activities generated a consistent level of cash
compared with the corresponding amount for fiscal 1994. Tidewater Marine
operating margins primarily determine the overall level of cash generated from
operating activities. The following table compares operating margins for
Tidewater's business segments.

     Operating margins are defined as revenues less operating expenses,
excluding depreciation.

     Fluctuations in the level of Tidewater Marine operating margins over the
past three fiscal years were attributable primarily to decreased levels of
utilization for a smaller worldwide vessel fleet from fiscal 1994 to fiscal
1995 and higher utilization and average day rates for the domestic-based
vessel
                                      49
<PAGE>
fleet from fiscal 1993 to fiscal 1994. Fiscal 1995 Tidewater Compression
operating margins surpassed the prior year level principally due to a
substantial increase in the size of the natural gas compressor fleet. Fiscal
1994 Tidewater Compression operating margins were down slightly from fiscal
1993 due to an anticipated drop in sales of engineered products. For the past
several years operating activities have generated cash in excess of the amount
required to satisfy current obligations. Anticipated fiscal 1996 utilization
levels and day/rental rates for the Tidewater Marine vessel fleet and
Tidewater Compression rental equipment should maintain this condition.

     Investing activities for fiscal 1995 consumed a significantly larger
amount of cash compared with fiscal 1994. The principal reason for the
increase over the prior year level is the acquisition of the natural gas
compression assets of Halliburton Company in the third quarter of fiscal 1995
for approximately $205 million and the acquisition of the assets of Brazos Gas
Compressing Company for approximately $35 million at the end of the second
quarter of fiscal 1995. Additions to properties and equipment, excluding the
Brazos and Halliburton Compression acquisitions, and proceeds from asset sales
are compared by business segment in the following tables for the years ended

     Fiscal 1995 financing activities provided cash of $42.3 million primarily
due to borrowing $150 million to finance the Halliburton Compression
acquisition. The borrowing was under a $250 million amended and restated
Revolving Credit and Term Loan Agreement with several banks and bears interest
at fluctuating rates subject to certain options chosen in advance by
Tidewater. In addition to normal scheduled debt repayments, fiscal 1995
payments on long-term debt include $35.0 million of prepayments on debt
borrowed to finance the Halliburton Compression acquisition and approximately
$46.0 million for the early retirement of the 7% convertible subordinated
debentures called for redemption on March 16, 1994. Fiscal 1994 financing
activities include approximately $57.6 million to retire, prior to maturity,
$51.1 million of notes bearing interest rates ranging from 9.17% to 10%. The
remainder of the cash used to retire the notes was for associated prepayment
penalties. Fiscal 1994 principal payments also include approximately $9.0
million for termination of capitalized lease obligations and the related
purchase of five marine vessels. Fiscal 1993 cash used in financing activities
includes approximately $38.0 million for long-term debt retired prior to
maturity.

     On March 16, 1994, Tidewater called for redemption the approximately
$47.2 million of 7% convertible subordinated debentures due 2010. Holders
converted $1,113,000 of debentures into 44,520 shares of Tidewater's common
stock at a conversion price of $25.00 per share. The remainder of the
debentures were redeemed at 101.4% of par value plus accrued interest on April
18, 1995. An extraordinary charge to earnings of approximately $7.5 million
(net of income taxes), or $.14 per common share, was recorded in the fourth
quarter of fiscal 1994. The extraordinary charge consisted of $.6 million of
prepayment premium and $11.0 million of unamortized original issue discount
and deferred financing costs, less $4.1 million of income tax benefits.

     During fiscal 1993, dividends of $.075 per common share were declared and
paid in each of the first three quarters and a $.10 per common share dividend
was declared in the fourth quarter. Due to the timing of the meetings of the
Tidewater Board, three quarterly dividends were declared in fiscal 1994, each
at $.10 per common share. During fiscal 1995 dividends of $.10 per common
share were declared and paid in each quarter. Continued dividend payments are
subject to declaration by the Tidewater Board and are subject to limitation by
Tidewater's revolving credit and term loan agreement.

(A) For fiscal 1995 one Tidewater Marine customer accounted for approximately
    11% of consolidated revenues.

(B) Tidewater Marine equipment operations are conducted worldwide with assets
    that are highly mobile. Revenues and identifiable assets attributable to
    these operations in any one country are not "significant" as that term is
    defined by Financial Accounting Standards No. 14. Further, most
    identifiable assets in each country are comprised of offshore service
    vessels, which regularly and routinely move from one operating area to
    another, often to and from offshore operating areas of different
    continents. Equity in net assets of foreign subsidiaries is $224,905,000,
    $192,038,000 and $164,175,000 at March 31, 1993, 1994 and 1995,
    respectively. Other foreign identifiable assets include accounts
    receivable and other balances denominated in foreign currencies
    aggregating approximately $8,837,000, $7,295,000 and $7,062,000 at March
    31, 1993, 1994 and 1995, respectively. These amounts are subject to the
    usual risks of fluctuating exchange rates and government-imposed exchange
    controls.

     Fiscal 1995 consolidated revenues and pre-tax earnings rose 3.2% and
16.9%, respectively, above the corresponding amounts for the prior fiscal year
primarily due to significantly higher Tidewater Compression revenues and
operating profits and higher Tidewater Marine operating profits. The 109%
increase in fiscal 1995 Tidewater Compression operating profits over the prior
fiscal year is a result of the substantial expansion of the natural gas
compressor rental fleet during the second half of fiscal 1995. Higher fiscal
1995 Tidewater Marine operating profits were principally the result of higher
gains from sales of assets and shipyard profits partially offset by lower
operating profits for a smaller foreign-based vessel fleet. Shipyard profits
rose substantially above prior year levels due to the construction of vessels
for third-parties. Fiscal 1995 pre-tax earnings were adversely affected by
$8.4 million of other expense which consisted of a $5.9 million charge
resulting from the restructuring of Tidewater's worldwide marine operations
and its headquarters office and a $2.5 million provision for possible losses
due to the potential insolvency of certain of Tidewater's insurers.
Substantially all of the costs associated with the restructuring program were
paid before March 31, 1995. The primary effect of the restructuring on future
levels of costs and expenses will be to reduce annual payroll and related
costs by approximately $6.6 million. During fiscal 1995, the estimated salvage
value used to determine depreciation expense for natural gas compressors was
increased. Please see Note 1 of Notes to Consolidated Financial Statements for
further discussion of this matter.

     Fiscal 1994 consolidated revenues and earnings from continuing operations
before income taxes rose 9.7% and 43.5%, respectively, above the corresponding
amounts for the prior fiscal year primarily because of higher utilization and
substantially higher average vessel day rates for the domestic-based vessel
fleet. Fiscal 1994 revenues and operating profits for the foreign-based vessel
fleet reflect weaker demand in certain foreign markets resulting from
uncertainties associated with the then future supply and price of oil. Fiscal
1994 foreign operating profits also include a higher level of repair and
maintenance costs resulting from the timing of vessel drydockings. Lower
fiscal 1994 Tidewater Compression revenues and operating profits compared with
the corresponding amounts for the prior fiscal year are primarily the result
of a lower level of engineered product sales. Fiscal 1994 Tidewater Marine and
Tidewater Compression operating profits also include approximately $.3 million
and $1.0 million, respectively, of severance costs associated with the early
retirement of several employees.

     Fiscal 1993 non-recurring charges totaling $3.8 million relate to an
amendment of an employment and consulting agreement with Tidewater's then
chairman of the board, president and chief executive officer. For its benefit,
Tidewater elected to amend the agreement in view of the possible changes to
tax laws then under consideration by the Clinton administration and Congress.
The amendment accelerated the vesting of all outstanding shares of restricted
stock such that these shares became fully vested and freely transferable
immediately. The original terms of the restricted stock shares included
restrictions during the employment term of the agreement. Due to the
acceleration of the vesting of the restricted stock shares on March 31, 1993,
the remaining deferred compensation associated with the restricted stock of
$2,850,000 was charged to other expense in the Consolidated Statements of
Earnings in fiscal 1993.
                                      53

     The amendment also provided for an immediate lump-sum distribution of the
present value of benefits under Tidewater's supplemental retirement plan,
including the additional benefits that would have accrued assuming he remained
employed by Tidewater through September 24, 1994. The lump sum distribution
amounted to $2,212,000 and included $921,000 for unaccrued benefits which was
charged to other expense in the Consolidated Statements of Earnings in fiscal
1993.

     Consolidated general and administrative expenses for the years ended
March 31 consist of the following components:

TIDEWATER MARINE SEGMENT

     The Tidewater Marine segment provides a diverse range of services and
equipment to the offshore oil and gas industry. Because operating costs and
depreciation do not change proportionally with changes in revenues, the amount
of operating profit for the Tidewater Marine segment primarily is determined
by vessel fleet utilization and day rates.

     Tidewater Marine segment revenues for the years ended March 31 consist of
the following:

                                          1993         1994         1995

     Tidewater Marine fleet utilization is affected primarily by market
conditions. It is also influenced to a lesser degree by drydockings to satisfy
safety and inspection requirements because Tidewater Marine vessels must
undergo periodic inspections to remain properly classified and certified.
These inspections, whenever possible, are done during seasonally slow periods
to minimize the impact on vessel operations and are only done if the vessel is
considered to have continuing economic viability. The following table compares
day-based Tidewater Marine fleet utilization percentages by vessel class and
in total for the years ended March 31:

                                         1993       1994       1995

     The domestic fleet consists of vessels operating in U.S. waters while the
foreign fleet consists of vessels operating outside U.S. waters.

     Tidewater Marine vessel utilization for all periods presented reflects
demand trends for offshore marine services. Lower utilization of the worldwide
vessel fleet in fiscal 1995 compared with fiscal 1994 is the result of
decreased demand for offshore marine services resulting from lower U.S.
natural gas prices which negatively affected utilization of the domestic-based
vessel fleet. Instability in the price of oil weakened demand for offshore
marine services in foreign markets and, in turn, adversely affected
utilization of the foreign-based vessel fleet. Higher fiscal 1994 utilization
compared with fiscal 1993 of the domestic-based vessel fleet reflects
increased demand for offshore marine services in the U.S. Gulf of Mexico.
Higher demand resulted from increased natural gas exploration and drilling
activity which began late in the third quarter and continued through the
fourth quarter of fiscal 1993 and throughout most of fiscal 1994. Toward the
end of the fourth quarter of fiscal 1994, the normal seasonal slowdown of
offshore activity caused a slight drop in utilization. Fiscal 1994 utilization
of the foreign-based vessel fleet below the fiscal 1993 level results
primarily from softening demand for offshore marine services in certain
foreign markets, principally the West African market.

                                      55

     Tidewater 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. Suitability of equipment, the
degree of service provided and the overall supply of marine service vessels
also influence vessel day rates. The following table provides a comparison of
average day rates by vessel class and in total for the years ended March 31:

     The domestic fleet consists of vessels operating in U.S. waters while the
foreign fleet consists of vessels operating outside U.S. waters.

     Fiscal 1995 average day rates for the worldwide vessel fleet rose 4%
above the prior year level and was due primarily to the mix of vessels
working. Fiscal 1995 average vessel day rates for the foreign-based vessel
fleet were higher due to a much lower level of activity for the inshore towing
fleet in Nigeria. Because these vessels have much lower average day rates,
they positively affect the overall average day rate of the fleet as
utilization and the number of these vessels in the fleet declines. In fiscal
1994, a higher average day rate for a larger domestic-based vessel fleet was
the principal factor contributing to the growth in Tidewater Marine revenues
and operating profits. During fiscal 1994 average day rates for the
domestic-based vessel fleet rose steadily in contrast to fiscal 1993, when
average day rates for a smaller vessel fleet declined. The average day rate
for the foreign-based vessel fleet for fiscal 1994, although higher than the
fiscal 1993 average day rate, did not significantly change compared with the
ending fiscal 1993 level. The fiscal 1994 increase in the average day rate for
the foreign-based vessel fleet primarily is a result of a favorable shift in
the mix of vessels working in certain foreign locations.

     As the global supply of marine service vessels continues to decline,
prospects for higher average vessel day rates improve. However, given the
volatile nature of demand for offshore marine services, any sustained
improvement in vessel day rates is not assured.

     The drop in average size of the foreign-based vessel fleet from 346 for
fiscal 1994 to 318 for fiscal 1995 is due to several vessels being withdrawn
from active service due to age and anticipated high repair and maintenance
costs, the transfer of vessels to the domestic-based vessel fleet and the
return of vessels to their owners that could not be operated profitably under
current market conditions. Additional vessels in the Tidewater Marine fleet
may be withdrawn in the future as they become uneconomical to operate.

(A) Costs incurred from the charter of equipment to the discontinued Tidewater
    Container Shipping segment.

     Changes in fleet size and utilization are the principal factors which
cause fluctuations in the amount of crew costs. The drop in fiscal 1995 crew
costs from fiscal 1994 is primarily the result of lower activity for a smaller
worldwide fleet. Higher fiscal 1994 crew costs compared with fiscal 1993
principally are the result of the higher activity level of the domestic-based
vessel fleet, which generally has higher crewing costs than the foreign-based
vessel fleet, and the addition of 19 vessels purchased on March 15, 1993. The
absence of significant new vessel construction within the energy services
industry over the past 10 to 12 years has caused the average age of Tidewater
Marine's vessel fleet to rise. Currently the average age of the Tidewater
Marine's vessel fleet is approximately 16 years. The increase in average age
of the fleet combined with normal inflationary effects has, in turn, resulted
in higher levels of repair and maintenance costs. Though primarily dictated by
regulatory agencies, the scheduling of vessel drydockings affects the amount
of repair and maintenance expense in any year. Vessel drydockings, whenever
possible, are also done to minimize any impact on vessel revenues. Higher
fiscal 1995 insurance costs compared with the prior periods are primarily the
result of general insurance market conditions. Other vessel costs for fiscal
1993 include approximately $2.0 million of write-offs which resulted from a
comprehensive review of marine inventories and a significantly higher amount
of broker commissions.

     Gains on asset sales contributed $2.9 million, $3.3 million and $12.4
million for the fiscal years ended March 31, 1993, 1994 and 1995,
respectively. Operating margins from brokered vessel activity generally
contribute nominally to Tidewater Marine operating profits.

TIDEWATER COMPRESSION SEGMENT

     The Tidewater Compression segment provides natural gas compression
services and equipment for a variety of applications primarily in the energy
industry. It also designs, fabricates and installs engineered compressor
systems. Tidewater Compression operating profit primarily is determined by
operating margins from natural gas compressor operations.

     During the second half of fiscal 1995, Tidewater purchased the natural
gas compression assets of Halliburton Company for approximately $205 million
and on September 30, 1994 purchased the assets of Brazos Gas Compressing
Company, a subsidiary of Mitchell Energy & Development Corporation, for
approximately $35 million. The Halliburton Compression fleet consisted of
approximately 1,550 units aggregating approximately 237,000 horsepower. The
Brazos fleet consisted of approximately 325 units aggregating approximately
58,000 horsepower. These acquisitions have made the Tidewater Compression
segment the leader in the domestic gas compression industry and improve its
ability to service the needs of its customers.
    
     Tidewater Compression segment revenues for the years ended March 31
consist of the following:

     Gas compressor utilization is affected primarily by natural gas storage
levels and by the number and age of producing oil and gas wells which, in
turn, are dependent upon the price levels of oil and natural gas. Quality of
service, availability and rental rates for gas compression equipment also are
major factors which affect utilization. The following table compares
horsepower-based utilization, average rental rates and average fleet size for
natural gas compressors for the years ended March 31 and the actual fleet size
at March 31 of the respective years:

     For the first six months of fiscal 1995, utilization rose above the level
experienced for the corresponding fiscal 1994 period as demand for natural gas
compression services remained firm primarily due to the then favorable
long-term outlook for U.S. natural gas prices. As U.S. natural gas prices
continued to decline during the third and fourth quarters of fiscal 1995,
demand for gas compression services weakened and, in turn, utilization was
adversely affected. The integration of the Brazos and Halliburton natural gas
compressor fleets during the second half of fiscal 1995, which fleets had
historically experienced lower levels of utilization than the pre-acquisition
Tidewater natural gas compressor fleet, further reduced overall fiscal 1995
utilization. Higher fiscal 1995 average rental rates compared with fiscal 1994
primarily are attributable to the composition of equipment in the combined
fleet. Higher fiscal 1994 utilization and higher average monthly rental rates
compared with fiscal 1993 are a direct result of greater demand for natural
gas compressor services as a result of higher U.S. natural gas prices. Fiscal
1994 gas compressor rental revenues also rose as a result of a larger
compression fleet.

     Fluctuations in the level of revenues generated from equipment and parts
sales over the past three fiscal years primarily are the result of changes in
the sales volume of engineered products. For fiscal 1995 the increase is also
attributable to higher parts sales in Canada.

     Field operating expenses relate primarily to gas compressor rental,
repair and service operations. Field operating expenses generally are
consistent from period-to-period and usually vary in the short-term due to
fluctuations in the level of repairs and maintenance expense. Long-term growth
in field operating expenses will occur primarily as a result of increased
fleet size and general inflationary factors. Higher fiscal 1995 field
operating expenses are a direct result of the substantial expansion of the
natural gas compressor fleet. Costs of sales consist primarily of wages and
benefits and material costs associated with the design, fabrication and
installation of packaged compressor systems. Fluctuations in costs of sales as
a percentage of the related revenues over the past three years generally are
due to competitive forces and the type of equipment sold.

     Gains on sales of equipment over the past three years contributed $1.4
million, $1.3 million and $1.1 million for the fiscal years ended March 31,
1993, 1994 and 1995, respectively.

CURRENCY FLUCTUATIONS AND INFLATION

     Because of its significant foreign operations, Tidewater is exposed to
currency fluctuations and exchange risks. To minimize the financial impact of
these items Tidewater attempts to contract a majority of its services in
United States dollars. Day-to-day operating costs generally are affected by
inflation. However, because the energy services industry requires specialized
goods and services, general economic inflationary trends may not affect
Tidewater's operating costs. The major impact on operating costs is the level
of offshore exploration and development 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 Tidewater from the inflationary effects on operating costs.

ENVIRONMENTAL MATTERS

     During the ordinary course of business Tidewater's operations are subject
to a wide variety of environmental laws and regulations. Tidewater attempts to
comply with these laws and regulations in order to avoid costly accidents and
related environmental damage. Tidewater currently is involved in litigation
with the Environmental Protection Agency (EPA) concerning the legal disposal
of oilfield wastes from drilling sites it previously operated, as well as from
the disposal of other fluids used in the marine operations.

     In 1983, the United States Environmental Protection Agency (the "EPA")
notified two subsidiaries of Tidewater, Zapata Gulf Marine Operators, Inc.
("Zapata Gulf") and Gulf Fleet Supply

                                      60
<PAGE>
Vessels, Inc. ("Gulf Fleet") that they were potentially responsible parties
("PRPs") for cleanup costs at the Western Sand and Gravel site in Rhode
Island. Zapata Gulf and Gulf Fleet are among 53 PRPs.
   
     In August of 1989, the EPA notified a subsidiary of Tidewater, Hilliard
Oil & Gas, Inc. ("Hilliard"), that it was a PRP for cleanup costs at a
National Priorities List site. EPA later nominated Hilliard a de minimis
participant for this site, i.e. EPA determined that Hilliard's involvement in
the site was minimal, and that the toxicity and amount of substance
contributed by Hilliard was minimal in comparison to the other hazardous
substances found at the site. EPA alleges that residue from trucks
transporting Hilliard's saltwater (a non-hazardous substance) to a third party
site subsequently was washed out of the trucks' tanks at the subject site,
thus making Hilliard a PRP for cleanup of the subject site. Hilliard believes
that this is an insufficient nexus to establish liability, and has chosen to
challenge EPA on this theory.

     Based on its evaluation of the potential total clean-up costs, its estimate
of its potential exposure, and the viability of other PRPs, management believes
that any costs ultimately required to be borne by Tidewater at these sites will
not have a material adverse effect on its results of operations, cash flow or
financial position.

               HORNBECK MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following is a discussion of the financial condition and results of
operations of Hornbeck. This discussion should be read in conjunction with the
information contained in the consolidated financial statements of Hornbeck and
the related notes included herein.

GENERAL

     Hornbeck's operating revenue is directly affected by average day rates
and fleet utilization, which are closely aligned with the offshore oil and gas
exploration and development industry. The level of exploration and development
of offshore areas is affected by both short-term and long-term trends in oil
and gas prices which, in turn, are related to the demand for petroleum
products and the current availability of oil and gas resources. Although
different geographic markets were affected at different times and to varying
degrees, the level of activity in the oil and gas exploration and development
industry and, therefore, the offshore marine services industry, was depressed
in the Gulf during the middle and late 1980s. In the period from 1988 through
the first half of 1995, the Gulf of Mexico's market experienced several
periods of increased offshore activity as well as periods, both seasonal and
otherwise, where demand for offshore marine services decreased. Many industry
experts anticipate that increased natural gas demand will increase drilling
and workover activity in the Gulf. On the other hand, a reduced level of oil
and gas prices could lead to less exploration and development of offshore
areas, reduced activity for the offshore marine services industry, and an
adverse effect on Hornbeck's financial condition and results of operations. In
the North Sea, following Hornbeck's 1993 acquisition of Ravensworth, safety
standby vessel demand declined due to lower drilling activity caused by oil
price declines and certain tax law changes affecting that area. In 1995, the
industry has experienced increased drilling activity in the North Sea;
however, there is a relatively small oversupply of safety standby vessels
available for charter which is causing a weakness in that market. Recently,
advances in technology used in exploring for and developing oil and gas
reserves has increased drilling success rates and efficiency contributing to
higher offshore drilling activity levels. Oil and gas exploration and
production companies can develop reserves in a lower energy price environment
because of this improved technology which has led to lower finding costs.
Hornbeck cannot predict future demand levels for its markets.

     The offshore marine services industry is cyclical, with periods of
increased demand for services resulting in higher utilization and day rates
and periods of lower demand resulting in lower utilization and day rates. An
upward or downward movement in day rates has little direct impact on operating
costs and expenses for a vessel. An increase or decrease in utilization of a
vessel will incrementally increase or decrease certain operating costs and
expenses but generally not in proportion to the associated revenue change.

     Hornbeck's results of operations have not been significantly affected by
inflation during the past five years. Since Hornbeck's investment in
Ravensworth in mid-1993, it has become exposed to potential foreign exchange
gains or losses. Through September 30, 1995, Hornbeck has not recorded any
significant foreign exchange gains or losses.

LIQUIDITY AND CAPITAL RESOURCES

     Cash provided from operating activities totaled $17,584,000 for the first
nine months of 1995, compared to $17,105,000 in the same period of the prior
year. Hornbeck had cash and equivalents of $19,625,000 at September 30, 1995.
The change in operating cash flow occurred primarily as a result of an
increase in average fleet size offset significantly because of lower day rates
which resulted in lower revenues and cash receipts on a per vessel basis.

     At December 31, 1994, Hornbeck had cash and equivalents of approximately
$8,572,000. For the year ended December 31, 1994, a period of downturn in the
offshore marine services business, cash provided by operating activities
totaled approximately $19,148,000, an increase of $2,919,000 versus the amount
reported for 1993.

     In connection with the Oil & Gas Vessel Acquisition, Hornbeck entered
into a loan agreement (the "Loan Agreement") with a bank (for itself and as
agent for any future lenders who may participate in the loans under the Loan
Agreement) to provide a portion of the funds for the Oil & Gas Vessel
Acquisition and a revolving credit facility. Under the Loan Agreement,
Hornbeck obtained a term loan in the amount of $20 million, payable over a
five-year period in quarterly installments of $714,284 which began March 31,
1995, with the balance due November 15, 1999. The term loan is secured by the
13 vessels acquired in the Oil & Gas Vessel Acquisition. The Loan Agreement
also provides for a revolving credit facility of up to $10 million based on a
Borrowing Base (as defined in the Loan Agreement) comprised of eligible
accounts receivable of Hornbeck and its subsidiaries. The loans bear interest
at the bank's prime rate or, at the election of Hornbeck, at LIBOR plus 1%.

     If the Merger is not consummated, Hornbeck anticipates it will be able to
generate sufficient cash flow from operations to meet its debt repayment and
capital expenditure requirements and be in a position to invest a portion of
its cash flow in other acquisitions in the offshore marine services industry.
Planned growth will be funded through future cash flow and/or additional debt
or equity financing. Hornbeck believes that it possesses sufficient
unencumbered assets (recognizing that only 22 of the 56 U.S. flag vessels in
which Hornbeck has an ownership interest constitute collateral for outstanding
debt) to support future debt financing. At September 30, 1995, Hornbeck had
long-term debt totalling approximately $18 million.

     Pursuant to an option agreement entered into in connection with the
Ravensworth Acquisition, Hornbeck may acquire the remaining 50.1% of
Ravensworth equity that it does not presently own between the date of this
Proxy Statement/Prospectus and March 31, 1997. The option price will bear
interest from the original acquisition date and the option prices are subject
to upward or downward adjustment based on actual Ravensworth EBDIT
performance. Performance of the North Sea Manager and of Seaboard is combined
with that of Ravensworth for purposes of making such EBDIT calculations. Based
on Ravensworth's EBDIT performance in 1994, the option price for the 9.9%
option exercised effective July 23, 1993 as part of the Ravensworth
Acquisition was adjusted downward by approximately $1,800,000, resulting in
the surrender and cancellation of approximately 106,000 shares of Hornbeck's
common stock originally issued as partial consideration for such option
exercise. Calculations based on existing 1995 EBDIT figures indicate that
there will be a reduction in the option price. Without taking into account any
performance adjustment and assuming the exercise of two equal annual options
to purchase the remaining Ravensworth equity on or before March 31, 1996 and
March 31, 1997, respectively, the total future purchase price, including
interest, would result in a payment of approximately $5.7 million in cash
together with $11.4 million of Common Stock. See "The Merger -- Conduct of
Business of Hornbeck Pending the Merger" with respect to restrictions on the
exercise of the Ravensworth Options. Pursuant to option agreements entered
into in connection with the Seaboard Acquisition and the formation of North
Sea Manager, Hornbeck may acquire the remaining 50.1% of North Sea Manager and
Seaboard that it does not presently own. In connection with the exercise of
its options to acquire the remaining outstanding capital stock of Ravensworth,
Hornbeck will be entitled to receive for no additional consideration a
corresponding amount of the remaining equity interests in North Sea Manager.
If Hornbeck has exercised its options to acquire the remainder of the capital
stock of Ravensworth, Hornbeck may exercise an option to acquire the remaining
outstanding capital stock of Seaboard for nominal consideration through June
30, 1999, and thereafter at the appraised value of the Seaboard fleet and
associated assets less the outstanding debt and a provision for contingent
liabilities of Seaboard and its subsidiaries.

     Hornbeck's commitments for future capital expenditures are not material.
Hornbeck is subject to regulations which require supply vessels to be
drydocked twice in a five-year period and, therefore, each year a portion of
Hornbeck's vessels undergo routine drydocking for maintenance and repairs.

RESULTS OF OPERATIONS

     NINE MONTHS ENDED SEPTEMBER 30, 1995 VERSUS NINE MONTHS ENDED SEPTEMBER
30, 1994:  Revenues increased by $9,600,000 or 30% from $31,731,000 in the
first nine months of 1994 to $41,331,000 in the first nine months of 1995.
Relevant fleet statistics affecting Hornbeck's revenues are as follows:

                                        NINE MONTHS ENDED
                                          SEPTEMBER 30,
                                        -----------------
                                         1994       1995
                                        -------    -------
Average supply vessel dayrate........   $ 3,332    $ 3,108
Average fleet utilization............        75%        80%
Number of vessels in fleet at end of
  period.............................        53         61

     Revenues increased due to the increased fleet utilization and the larger
number of vessels in the fleet. This increase was partially offset by the
impact of lower day rates. Direct labor and other operating expenses increased
from $16,744,000 in the first nine months of 1994 to $21,550,000 in the first
nine months of 1995, an increase of $4,806,000 or 29%. This increase is due to
the increased fleet utilization and the increased number of vessels in the
fleet in 1995. Depreciation and amortization also increased because of the
acquisition of vessels since September of 1994. Average depreciation on a per
vessel basis increased in 1995 because vessels acquired since September of
1994 cost more than the average vessel in the existing fleet. General and
administrative expenses increased $396,000 or 15% from $2,602,000 in the first
nine months of 1994 to $2,998,000 in the first nine months of 1995 primarily
because of the increase in shore-based staff to support the increased fleet
size and higher legal fees.

     Hornbeck reported a gain on the sale of assets totaling $427,000 for the
first nine months of 1995 which is primarily attributable to the sale of a
vessel in June 1995 compared to a gain of $694,000 reported in the first nine
months of 1994, a decrease of $267,000. Hornbeck also reported a loss of
$335,000 representing its share of losses of certain affiliates for the nine
months ended September 30, 1995 as compared to income of $1,362,000 in the
same period of the prior year. The North Sea Group recognized losses because
of lower revenues due primarily to decreased utilization and day rates.
Interest expense increased $810,000 or 151% because of the additional
borrowings made in November 1994 in connection with the Oil & Gas Vessel
Acquisition.

     Income taxes represent a lower or higher percentage of pretax income than
an expected "statutory" rate of approximately 35% due primarily to the fact
that no income tax effect is recognized for Hornbeck's equity in earnings of
foreign affiliates. Additionally, in 1995, certain property taxes paid on
vessels generate state income tax credits which lower effective state tax
rates.

     YEAR ENDED DECEMBER 31, 1994 VERSUS YEAR ENDED DECEMBER 31,
1993.  Revenues declined by $1,457,000 or 3% in 1994 compared to 1993. The
primary cause for this reduction was the decline in overall fleet utilization
in 1994 to 80% compared to 85% in the prior year. Relevant fleet statistics
affecting Hornbeck's revenues are as follows:

                                           YEAR ENDED
                                           DECEMBER 31,

  period.............................        51         63(1)

- ------------

(1) Includes 13 vessels acquired on November 15, 1994.

     Although day rates averaged approximately the same in 1993 and 1994,
market conditions differed significantly. Day rates increased during 1993,
reaching approximately $4,000 per day for average supply vessel rates by the
end of 1993. Day rates declined in 1994 through the middle of the year to
approximately $3,000 per day, remained steady in much of the third quarter and
increased in

                                      64
<PAGE>

the fourth quarter of 1994 to slightly over $3,200 on average. Utilization
declined in the first half of 1994, then increased in the second half of the
year.

     Direct labor and other operating expenses increased by $2,896,000 or 14%
in 1994 compared to 1993. Most of this increase was attributable to higher
insurance premiums and insurance deductibles paid by Hornbeck in 1994.
Additionally, labor increased by 8.5% due to crewmembers' wage rate
adjustments and payroll taxes related thereto. Generally, operating costs and
expenses do not change in direct proportion to revenues.

     Depreciation and amortization increased 35% because of increased
depreciation in 1994 on vessels purchased and because of a $1,630,000 increase
in amortization of deferred drydocking costs compared to 1993 due to a larger
fleet size that caused higher levels of deferred drydocking.

     General and administrative expenses increased 22% because of an increased
number of shore-based employees required to support Hornbeck's increased
fleet, both domestically and overseas, and because of higher insurance,
travel, franchise tax and stockholder-related expenses associated with a
larger company.
   
     Equity in earnings of affiliates increased due to the inclusion in 1994 of
such earnings for all of 1994 compared to inclusion in 1993 from only the July
1993 Ravensworth Acquisition date. Full-year operating income of affiliates was
actually down in 1994 compared to 1993 due to lower day rates in 1994.
Utilization and day rates averaged approximately 84% and pounds sterling 3,637,
respectively, during the period subsequent to the Ravensworth Acquisition in
1993 and 71% and pounds sterling 3,607, respectively, during calendar year 1994.
The gain on sale of assets relates to three vessels sold during the second
quarter of 1994. Interest and other income increased primarily because of higher
levels of investment and interest rates in 1994. Interest expense declined
because of debt repayments in early 1994.
    
     YEAR ENDED DECEMBER 31, 1993 VERSUS YEAR ENDED DECEMBER 31,
1992.  Revenues and expenses increased substantially in 1993 compared to 1992.
These increases are primarily the result of increases in the number of vessels
in Hornbeck's fleet due to the November 1992 Petrol Acquisition, increases in
the average supply vessel dayrate and increases in the average fleet
utilization as reflected in the following table:

                                           YEAR ENDED
                                           DECEMBER 31,
                                        ------------------
                                         1992       1993
                                        -------    -------
Average supply vessel dayrate........   $ 1,995    $ 3,284
Average fleet utilization............        80%        85%
Number of vessels in fleet at end of
  period.............................        52         51

     The increased day rates and utilization were caused primarily by
increased drilling activity in the Gulf of Mexico. The range of average day
rates in 1993 for Hornbeck increased from approximately $2,800 per day at the
beginning of the year to approximately $4,100 per day by the end of the year.

     Revenues increased $28,856,000 or 157% from $18,435,000 in 1992 to
$47,291,000 in 1993. The significant increase was primarily attributable to
higher utilization and day rates and the increase in the average number of
vessels in Hornbeck's fleet.

     Direct labor and other operating expenses increased $9,358,000 or 83% in
1993 compared to 1992 primarily because of the significantly larger number of
vessels in the fleet and higher utilization. Generally, operating costs and
expenses do not change in direct proportion to revenues.

     Depreciation and amortization increased by 56% in 1993 compared to 1992
because of additional vessels purchased in late 1992 and higher drydocking
amortization.

     General and administrative expenses increased 56% from $1,889,000 in 1992
to $2,938,000 in 1993 primarily because of the addition of personnel resulting
from the Petrol Acquisition in late 1992.

     Net income increased $10,603,000 from net income of $62,000 ($.01 per
share) in 1992 to a net income of $10,665,000 ($.90 per share) in 1993
primarily because of the larger fleet size and the higher day rates and
utilization discussed above. The increase in net income was partially offset
by nonrecurring salvage expense of $945,000 recorded in 1993.

     The payment of dividends on Tidewater Common Stock and its preferred
stock are subject to limitations under Tidewater's revolving credit and term
loan agreement, although no preferred stock is currently outstanding. None of
such limitations are currently expected to restrict Tidewater's continued
payment of dividends at current levels. A further discussion of this matter is
contained in Note 7 of the Notes to Tidewater's Consolidated Financial
Statements included elsewhere herein. As a result of the timing of the fiscal
1994 Tidewater Board meetings, only three quarterly dividends were declared
during fiscal 1994 with respect to Tidewater Common Stock.

     On November 17, 1995, the last trading day before the date that Tidewater
and Hornbeck publicly announced the proposed Merger, the closing sale price
for a share of Tidewater Common Stock on the New York Stock Exchange was
$28 3/4. No assurance can be given as to the Average Market Price or the
market price of Tidewater Common Stock at the Effective Time.

                     DESCRIPTION OF TIDEWATER SECURITIES

     The following description of the Tidewater Common Stock should be read
carefully by Hornbeck stockholders.

COMMON STOCK

     GENERAL.  Tidewater is currently authorized to issue 125,000,000 shares
of Tidewater Common Stock, $.10 par value per share. At December 31, 1995,
Tidewater had outstanding 53,337,457 shares of Tidewater Common Stock and no
shares were held in its treasury. At December 31, 1995, approximately
2,690,581 shares of Tidewater Common Stock were reserved for issuance upon
exercise of outstanding stock options under Tidewater's stock option and
restricted stock plans.

     Tidewater has a dual stock certificate system which distinguishes between
U.S. citizen holders of Tidewater Common Stock and non-U.S. citizen holders of
Tidewater Common Stock. If on any date, the number of shares of Tidewater
Common Stock that is beneficially owned by non-U.S. citizens is in excess of
24%, Tidewater shall identify and designate those shares, in excess of 24% of
the outstanding shares of Tidewater Common Stock, that are owned by non-U.S.
citizens (the "Excess Shares"). The Excess Shares shall not be accorded any
voting rights and shall not be deemed outstanding for purposes of determining
the vote required on any matter properly brought before the Tidewater
stockholders for a vote thereon. Tidewater shall (as long as such excess
exists) withhold the payment of dividends and the sharing in any other
distribution (upon liquidation or otherwise) with respect to the Excess
Shares. Only at such time as the non-U.S. citizen beneficial ownership returns
to a percentage below 24% shall full voting rights be restored to those Excess
Shares and any dividend or distribution with respect thereto that has been
withheld shall be due and paid. In addition, Tidewater has the power, but not
the obligation, to redeem the Excess Shares, subject to certain terms and
conditions contained in its Certificate of Incorporation.

     DIVIDEND RIGHTS.  Subject to the restrictions contained in the
Certificate of Incorporation, the holders of Tidewater Common Stock are
entitled to receive, when and as declared by the Tidewater Board, out of the
assets of Tidewater which are by law available therefor, dividends payable
either in cash, in property, or in shares of stock, provided that no dividends
other than dividends payable only in shares of Tidewater Common Stock shall be
paid on the Tidewater Common Stock if cash dividends accrued on any shares of
preferred stock shall not have been fully paid or declared and set apart for
payment.

     VOTING RIGHTS.  Subject to the restrictions contained in Tidewater's
Certificate of Incorporation, at every meeting of the stockholders, every
holder of Tidewater Common Stock shall be entitled to one vote, in person or
by proxy, for each share of Tidewater Common Stock standing in his name on the
books of the corporation. Holders of shares of Tidewater Common Stock have
noncumulative voting rights, which means that the holders of more than 50% of
the shares voting for the election of directors can elect 100% of the
directors, and, in such event, the holders of the remaining shares voting for
the election of directors will not be able to elect any directors. In
addition, the vote of 80% of the outstanding shares of Tidewater Common Stock
entitled to vote on the following matters is required to authorize (i) the
adoption of any agreement for the merger or consolidation of Tidewater with or
into any other corporation, and (ii) the sale or lease of all or a substantial
part of the assets of Tidewater to, or any sale or lease to Tidewater or any
subsidiary of Tidewater or any subsidiary thereof, in exchange for securities
of Tidewater, of any assets (except assets having an aggregate fair market
value of less than $5,000,000) of any other corporation, person or entity
(either of such events, a "change in control") if in either case such
corporation, person or entity is the beneficial owner, directly or indirectly,
of more than 10% of the outstanding shares of Tidewater Common Stock entitled
to vote in the election of directors. Such affirmative vote or consent is in
addition to any vote or consent of the holders of Tidewater Common Stock that
is otherwise required by law or by agreement between Tidewater and any
national securities exchange.

                                      68
<PAGE>
   
     RIGHTS UPON LIQUIDATION.  In the event of any dissolution, liquidation or
winding up of the affairs of Tidewater, either voluntarily or involuntarily, the
holders of the Tidewater Common Stock shall be entitled, after payment or
provision for payment of the debts and other liabilities of Tidewater and the
amounts to which the holders of any preferred stock shall be entitled, to share
ratably in the remaining assets of Tidewater. Neither the merger nor
consolidation of Tidewater, nor the sale, lease or conveyance of all or part of
its assets, shall be deemed to be a liquidation, dissolution or winding up of
the affairs of Tidewater.

     MISCELLANEOUS.  The issued and outstanding shares of Tidewater Common
Stock are fully paid and nonassessable. Holders of the shares of Tidewater
Common Stock are not entitled to preemptive rights. Shares of Tidewater Common
Stock are not convertible into the shares of any other class of capital stock.
    
     TIDEWATER RIGHTS.  Tidewater has adopted the Tidewater Stockholder Rights
Plan which is intended to protect stockholders in the event of unsolicited
offers or attempts to acquire Tidewater, including offers that do not treat
all stockholders equally, acquisitions in the open market of shares
constituting control without offering fair value to all stockholders and other
coercive or unfair takeover tactics that could impair the Tidewater Board's
ability to represent stockholders' interests fully. Pursuant to the Tidewater
Stockholder Rights Plan, the Tidewater Board declared a dividend distribution
of one Tidewater Right for each outstanding share of Tidewater Common Stock to
stockholders of record at the close of business on May 7, 1990, and authorized
the issuance of one Tidewater Right (as adjusted pursuant to the Tidewater
Stockholder Rights Plan) for each share of Tidewater Common Stock issued
between the Record Date and the Distribution Date (as defined below). Each
Tidewater Right entitles the registered holder to purchase from Tidewater one
two-hundredths of a share of Tidewater's Series A Participating Preferred
Stock at a price of $50, subject to adjustment (the "Purchase Price"). The
Rights are exercisable, and separate from the Tidewater Common Stock, only if
(i) a person acquires beneficial ownership of 16% or more of the outstanding
shares of Tidewater Common Stock (an "Acquiring Person"), or (ii) a person
commences a tender or exchange offer that, upon its consummation, would result
in such person beneficially owning 16% or more of the outstanding shares of
Tidewater Common Stock (the date of the occurrence of either of the foregoing
events will be termed the "Distribution Date"). Under certain circumstances
Tidewater may substitute an equivalent value of other securities of Tidewater,
property, cash, or any combination thereof in lieu of the Series A
Participating Preferred Stock. The Rights expire on May 1, 2000.
   
     If any person becomes the beneficial owner of 16% or more of the
outstanding shares of Tidewater Common Stock, except pursuant to an offer for
all outstanding shares of Tidewater Common Stock that is deemed by the
Tidewater Board to be fair and otherwise in the best interests of Tidewater
and its stockholders, then each Right not owned by the Acquiring Person (or
certain of its transferees) will enable the holder to purchase, at the then
current Purchase Price of the Right, Tidewater Common Stock (or, in certain
circumstances, a combination of Tidewater Common Stock, other securities, cash
or other property) having a calculated value of twice the Purchase Price of
the Right. In addition, if, after someone becomes an Acquiring Person,
Tidewater is acquired in a merger or other business combination transaction or
more than 50% of its assets, cash flow or earning power is sold, each Right will
entitle its holder to purchase, at the then current Purchase Price of the Right,
common stock of the acquiring company having a calculated value of twice the
applicable Purchase Price. The events referred to in this paragraph are
hereinafter referred to as "Triggering Events."
    
     The Tidewater Board may redeem the Rights at $.01 per Right at any time
before the tenth day following a public announcement that a 16% position has
been acquired. This right of redemption will be reinstated if, before the
occurrence of a Triggering Event, an Acquiring Person reduces its beneficial
ownership to less than 10% of the outstanding Tidewater Common Stock (other
than in a transaction with Tidewater) and there are no other Acquiring
Persons.

     The terms of the Rights, other than the principal economic terms, may be
amended by the Tidewater Board in any manner before the Rights are
distributed. Before such time the Tidewater

                                      69
<PAGE>

Board may also amend the terms and conditions of the Series A Participating
Preferred Stock or change the series or class of preferred stock which shall
constitute the preferred stock for purposes of the Tidewater Stockholder
Rights Plan. Thereafter, the Tidewater Stockholder Rights Plan may be amended
by the Tidewater Board in order to cure any ambiguity, to make changes that do
not adversely affect the interests of holders of Rights, or to shorten or
lengthen any time period under the Tidewater Stockholder Rights Plan;
provided, however, that no amendment to adjust the time period governing
redemption shall be made at such time as the Rights are not redeemable.

PREFERRED STOCK

     Tidewater is authorized to issue 3,000,000 shares of preferred stock, no
par value. Tidewater has no preferred stock outstanding at present, but has
designated and reserved 200,000 shares of Series A Participating Preferred
Stock to cover its obligations under the Tidewater Stockholder Rights Plan.
See "Description of Tidewater Securities -- Common Stock."
   
     The Tidewater Board is authorized to fix for each class or series of
preferred stock issued such voting powers, full or limited, or no voting
powers, and such distinctive designations, preferences and relative,
participating, optional or other special rights and such qualifications,
limitations or restrictions thereof, as shall be stated and expressed in the
resolution or resolutions adopted by the Tidewater Board providing for the
issuance of such class or series and as may be permitted by the DGCL,
including, without limitation, the authority to provide that any such class or
series may be (i) subject to redemption at such time or times and at such
price or prices; (ii) entitled to receive dividends (which may be cumulative
or non-cumulative) at such rates, on such conditions, and at such times, and
payable in preference to, or in such relation to, the dividends payable on any
other class or classes or any other series; (iii) entitled to such rights upon
the dissolution of, or upon any distribution of the assets of, Tidewater; or
(iv) convertible into, or exchangeable for, shares of any other class or
classes of stock, or of any other series of the same or any other class or
classes of stock, of Tidewater at such price or prices or at such rates or
exchanges and with such adjustments; all as may be stated in such resolution
or resolutions issuing the class or series of preferred stock.

     There are no family relationships between the directors of Tidewater.
Tidewater's officers are elected annually by the Tidewater Board and serve for
one-year terms or until their successors are elected.

                      COMPARATIVE RIGHTS OF STOCKHOLDERS

     If the Merger is consummated, all holders of Hornbeck Common Stock will
become holders of Tidewater Common Stock. The rights of the stockholders of
both Tidewater and Hornbeck are governed by and subject to the provisions of
the Delaware General Corporation Law ("DGCL"); however, the rights of holders
of Hornbeck Common Stock and holders of Tidewater Common Stock following the
Merger will be governed by the Certificate of Incorporation and Bylaws of
Tidewater, rather than the provisions of the Certificate of Incorporation and
Bylaws of Hornbeck. The following is a brief summary of certain differences
between the rights of stockholders of Tidewater and the rights of stockholders
of Hornbeck and is qualified in its entirety by reference to the relevant
provisions of (i) the DGCL, (ii) the Restated Certificate of Incorporation of
Tidewater, as amended (the "Tidewater Certificate"), (iii) the Bylaws of
Tidewater (the "Tidewater Bylaws"), (iv) the Restated Certificate of
Incorporation of Hornbeck, as amended (the "Hornbeck Certificate"), and (v)
the Restated Bylaws of Hornbeck (the "Hornbeck Bylaws").

APPROVAL OF EXTRAORDINARY TRANSACTIONS

     The Tidewater Certificate requires the affirmative vote or consent of the
holders of 80% of all classes of stock of Tidewater entitled to vote in the
election of directors, voting as one class, to authorize (i) the adoption of
any agreement for the merger or consolidation of Tidewater with or into any
other corporation, and (ii) any sale or lease of all or any substantial part
of the assets of Tidewater to, or any sale or lease to Tidewater or any
subsidiary of Tidewater or any subsidiary thereof, in exchange for securities
of Tidewater, of any assets (except assets having an aggregate fair market
value of less than $5,000,000) of any other corporation, person or entity
(either of such events, a "change in control") if in either case such
corporation, person or entity is the beneficial owner, directly or indirectly,
of more than 10% of the outstanding shares of stock of Tidewater entitled to
vote in the election of directors. Such affirmative vote or consent is in
addition to any vote or consent of the holders of the stock of Tidewater that
is otherwise required by law or by agreement between Tidewater and any
national securities exchange.

     Tidewater has a sufficient number of unissued shares available to, and it
therefore may, within the limits imposed by applicable law and the rules of
any applicable stock exchange, issue sufficient shares of Tidewater Common
Stock to a holder so that such holder, together with the shares already held
by such holder, would have the number of shares of Tidewater's capital stock
required to prevent an acquirer from receiving the requisite supermajority
vote to effect a change in control.

     The foregoing supermajority provisions are not applicable to (i) any
change in control if the Tidewater Board has approved a memorandum of
understanding with the acquiring corporation, person or entity with respect to
the change in control before such corporation, person or entity becomes a
holder of more than 10% of the outstanding shares of stock entitled to vote in
elections of directors or (ii) any merger or consolidation of Tidewater with,
or any sale or lease to Tidewater or any subsidiary thereof of any of the
assets of, any corporation of which a majority of the outstanding shares of
all classes of stock entitled to vote in the election of directors is owned of
record or beneficially by Tidewater and its subsidiaries. The foregoing
provisions of the Tidewater Certificate may not be amended or repealed without
the affirmative vote or consent of the holders of 80% of all classes of
capital stock entitled to vote in the election of directors voting as one
class.

     The Hornbeck Certificate provides that the affirmative vote of the
holders of not less than 66 2/3% of the issued and outstanding shares of
Hornbeck Common Stock, voting as a single class, is required for stockholder
approval of (i) the merger of Hornbeck into, or with, one or more other
corporations; and (ii) the liquidation of Hornbeck.

VACANCIES ON THE BOARD OF DIRECTORS

     The Tidewater Bylaws provide that any vacancy on the Tidewater Board that
results from an increase in the number of directors may be filled by a
majority of the Tidewater Board then in office, provided that a quorum is
present. Any other vacancy occurring in the Tidewater Board may be filled by a
majority of the directors then in office, even if less than a quorum, or by a
sole remaining director.

     The Hornbeck Bylaws provide that any vacancy occurring in the Hornbeck
Board that results from an increase in the number of directors may be filled
by a majority of the directors then in office, although less than a quorum, or
by a sole remaining director. Any vacancy occurring when one or more directors
resign from the Hornbeck Board may be filled by a majority of the directors
then in office, including directors whose resignation will take effect
subsequent to the meeting in which any vacancies are filled.

OTHER PROVISIONS WITH POSSIBLE ANTI-TAKEOVER EFFECTS

     UNISSUED STOCK.  The Tidewater Board is authorized, without action of its
stockholders, to issue authorized but unissued common and preferred stock; see
"-- Approval of Extraordinary Transactions" above. The existence of
undesignated preferred stock and authorized but unissued common stock enables
the Tidewater Board to make more difficult or to discourage an attempt to
obtain control of Tidewater by means of a merger, tender offer, proxy contest
or otherwise, and thereby to protect the continuity of Tidewater's management.
If, in the due exercise of its fiduciary obligations, the Tidewater Board were
to determine that a takeover proposal was not in Tidewater's best interest,
such shares could be issued by the Tidewater Board without stockholder
approval in one or more transactions that might prevent or make more difficult
or costly the completion of the takeover transaction by diluting the voting or
other rights of the proposed acquirer or insurgent stockholder group, by
creating a substantial voting block in institutional or other hands that might
undertake to support the position of the incumbent Tidewater Board, by
effecting an acquisition that might complicate or preclude the takeover, or
otherwise. With respect to undesignated preferred stock, the Tidewater
Certificate grants the Tidewater Board broad power to establish the rights and
preferences of the authorized and unissued preferred stock, one or more series
of which could be issued (i) entitling holders to vote separately as a class
on any proposed merger or consolidation; (ii) to elect directors having terms
of office or voting rights greater than those of other directors; (iii) to
convert preferred stock into a greater number of shares of Tidewater Common
Stock or other security; (iv) to demand redemption at a specified price under
prescribed circumstances related to a change of control; or (v) to exercise
other rights designed to impede a takeover. The terms of any such preferred
stock would be subject to certain limitations imposed by the New York Stock
Exchange. The issuance of shares of preferred stock pursuant to the authority
of the Tidewater Board described above may adversely affect the rights of the
holders of Tidewater Common Stock.
   
     PREFERRED STOCK PURCHASE RIGHTS.  As discussed above under "Description
of Tidewater Securities," Tidewater has issued Rights entitling the registered
holder to purchase shares of Series A Participating Preferred Stock. The
Rights will cause substantial dilution to a person or group that attempts to
acquire Tidewater without conditioning the offer on a substantial number of
Rights being redeemed. The Rights should not interfere with any merger or
other business combination approved by the Tidewater Board since the Tidewater
Board may, at its option, redeem the Rights for a redemption price of $.01 per
Right or amend the Tidewater Stockholder Rights Plan at any time before the
tenth day following a public announcement that an Acquiring Person has
acquired beneficial ownership of 16% or more of the Tidewater Common Stock.
    
     CLASSIFIED BOARD OF DIRECTORS.  The Tidewater Bylaws provide that
directors are elected for three-year terms, with approximately one-third of
the Tidewater Board standing for election each year. The Tidewater Bylaws
further provide that for the Tidewater stockholders to alter or repeal this
Bylaw the affirmative vote of the holders of not less than 80% of the votes
entitled to be cast by the holders of all stock entitled to vote in the
election of directors is required. In addition, Tidewater directors may

                                      74
<PAGE>

only be removed for cause. The Hornbeck Certificate and the Hornbeck Bylaws do
not provide for staggered terms of directors. Directors of Hornbeck may be
removed by its stockholders with or without cause.

     RESTRICTIONS ON TAKING STOCKHOLDER ACTION.  The Tidewater Bylaws provide
that a stockholder must notify Tidewater in advance of such holder's intent to
bring up items of business or nominate directors at any annual meeting of
stockholders. Under these provisions, a stockholder's notice must generally be
received by Tidewater not less than 75 days nor more than 100 days before the
anniversary date of the immediately preceding annual meeting of stockholders
of Tidewater. As permitted by the DGCL, the Tidewater Bylaws also eliminate
the ability of stockholders to call a special meeting of stockholders. In
addition, the Tidewater Certificate provides that any action required or
permitted to be taken by stockholders of Tidewater must be effected at a duly
called annual or special meeting of such stockholders and may not be effected
by any consent in writing by such stockholders.

     Hornbeck's charter documents do not limit the ability of stockholders to
submit items of business at annual meetings of stockholders or to act by
written consent as permitted by the DGCL. In addition, a special meeting of
Hornbeck stockholders may be called by the holders of not less than one
quarter of the stock entitled to vote at such meeting.

RESTRICTIONS ON TRANSFER

     The Tidewater Certificate and the Hornbeck Certificate each contain
similar provisions restricting the ownership of the common stock of each
company by persons who are not citizens of the United States. Aside from such
restrictions on foreign-owned shares, neither the Tidewater Certificate nor
Tidewater Bylaws contain any other restrictions on transfer of the Tidewater
Common Stock.

                                LEGAL MATTERS

     Jones, Walker, Waechter, Poitevent, Carrere & Denegre, L.L.P., New
Orleans, Louisiana has rendered an opinion that the shares of Tidewater Common
Stock to be issued in connection with the Merger have been duly authorized
and, if and when issued pursuant to the terms of the Merger Agreement, will be
validly issued, fully paid and non-assessable.

                                   EXPERTS

     The consolidated financial statements and schedule of Tidewater and
subsidiaries as of March 31, 1994 and 1995, and for each of the years in the
three-year period ended March 31, 1995 have been included herein and in the
registration statement in reliance upon the report of KPMG Peat Marwick LLP,
independent certified public accountants, appearing elsewhere herein, and upon
the authority of said firm as experts in accounting and auditing. The report
of KPMG Peat Marwick LLP covering the March 31, 1995 consolidated financial
statements refers to a change in the method of accounting for postretirement
benefits other than pensions in fiscal year 1993.

     With respect to the unaudited interim financial information of Tidewater
Inc. and subsidiaries for the periods ended June 30, 1994 and 1995 and
September 30, 1994 and 1995, included or incorporated by reference herein, the
independent certified public accountants have reported that they applied
limited procedures in accordance with professional standards for a review of
such information. However, their separate reports included in the June 30,
1995 Form 10-Q and the September 30, 1995 Form 10-Q, and incorporated by
reference herein, state that they did not audit and they do not express an
opinion on that interim financial information. Accordingly, the degree of
reliance on their reports on such information should be restricted in light of
the limited nature of the review procedures applied. The accountants are not
subject to the liability provisions of Section 11 of the Securities Act of
1933 for their reports on the unaudited interim financial information because
those reports are not a "report" or a "part" of the registration statement
prepared or certified by the accountants within the meaning of Sections 7 and
11 of the Securities Act.

     The consolidated financial statements of Hornbeck and subsidiaries as of
December 31, 1993 and 1994 and for each of the three years in the period ended
December 31, 1994 included in this Proxy Statement/Prospectus have been so
included in reliance on the report of Price Waterhouse LLP, independent
accountants, given on the authority of said firm as experts in auditing and
accounting.

                                OTHER MATTERS

     The Hornbeck Board knows of no business, other than that described above,
that will be presented at the Special Meeting but if any other matters
properly arise before the Special Meeting, the persons named in the enclosed

                         INDEPENDENT AUDITOR'S REPORT

The Board of Directors and Shareholders of Tidewater Inc.:

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

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

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Tidewater
Inc. and subsidiaries as of March 31, 1995 and 1994, and the results of their
operations and their cash flows for each of the years in the three-year period
ended March 31, 1995, in conformity with generally accepted accounting
principles. Also in our opinion, the related financial statement schedule,
when considered in relation to the basic consolidated financial statements
taken as a whole, present fairly, in all material respects, the information
set forth therein.

     As discussed in Note 1 to the consolidated financial statements, the
Company changed its method of accounting for postretirement benefits other
than pensions in fiscal 1993.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF CONSOLIDATION

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

INVENTORIES

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

PROPERTIES AND EQUIPMENT

     Properties and equipment are carried at cost. Depreciation for financial
reporting purposes is computed primarily on the straight-line basis beginning
with the first charter/rental, with salvage values of 5%-10% for marine
equipment and 30% for compression equipment, using estimated useful lives of:

                                        YEARS
                                        ------
Marine equipment (from date of
construction)........................   10-20
Compression equipment................    8-12
Other properties and equipment.......    3-30

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

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

     Effective April 1, 1995 the estimated useful lives of the company's
Marine vessels were increased from 10-20 years to 15-25 years. For the
six-month period ended September 30, 1995, the effect of this change in
accounting estimate lowered depreciation expense by $12.6 million. Concurrent
with this change, $4.5 million of repair and maintenance costs, that would
have been capitalized had the previous estimated useful lives been used, was
expensed.

     Effective with the third quarter of fiscal 1995 the Company increased
from 12 1/2% to 30% the estimated salvage value used to calculate depreciation
expense for its fleet of natural gas compressors. The increase in salvage
value was made in order to better reflect the estimated value of this
equipment at the end of its service life and resulted from an internal review
following the acquisition of a substantial number of natural gas compressors
during the third quarter of fiscal 1995. This change in accounting estimate
reduced depreciation expense by approximately $3 million and increased net
earnings by $1.9 million or $.04 per common share, for fiscal 1995. For fiscal
1996, the annual reduction in depreciation expense is estimated to be
approximately $7.3 million.

ACCRUED PROPERTY AND LIABILITY LOSSES

     The Company's insurance subsidiary establishes case basis reserves for
estimates of reported losses on direct business written, estimates received
from ceding reinsurers, and reserves based on past experience of unreported
losses. Such losses principally relate to the Company's marine operations and
are included as a component of costs of marine operations in the Consolidated
Statements of Earnings. The liability for such losses and the related
reimbursement receivable from reinsurance companies are

                                     F-7
<PAGE>
                       TIDEWATER INC. AND SUBSIDIARIES
          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

classified in the Consolidated Balance Sheet into current and noncurrent
amounts based upon estimates of when the liabilities will be settled and when
the receivables will be collected.

PENSION AND OTHER POSTRETIREMENT BENEFITS

     Pension costs are accounted for in accordance with the provisions of
Statement of Financial Accounting Standards No. 87 and are funded as required
by law. Prior service costs are amortized on the straight-line basis over the
average remaining service period of employees expected to receive pension
benefits. Effective April 1, 1992, postretirement benefits other than pensions
are accounted for in accordance with Statement of Financial Accounting
Standards No. 106. The estimated cost of postretirement benefits other than
pensions are accrued during the employees' active service period.
Postemployment and postretirement benefits other than pensions are funded as
claims are submitted.

INCOME TAXES

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

EARNINGS PER SHARE

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

FOREIGN CURRENCY TRANSLATION

     The functional currency for certain foreign subsidiaries and
unconsolidated companies is the applicable local currency. The translation of
the applicable local currencies into U.S. dollars is performed for balance
sheet accounts using current exchange rates in effect at the balance sheet
date and for revenue and expense accounts using weighted average exchange
rates during the period. The gains and losses resulting from the balance sheet
account translations, net of deferred income taxes, are included in
stockholders' equity.

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

CASH FLOWS

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

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

RECLASSIFICATIONS

     Certain reclassifications have been made in the 1994 amounts to conform
with the 1995 presentations.

INTERIM FINANCIAL STATEMENTS

     The consolidated financial information for the six-month period ended
September 30, 1994 and 1995 has not been audited by independent accountants,
but in the opinion of the management of Tidewater, all adjustments (consisting
only of normal recurring adjustments) necessary for a fair presentation of the
consolidated balance sheet, consolidated statement of earnings, consolidated
statement of stockholders' equity and consolidated statement of 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)  ACQUISITION OF COMPRESSION ASSETS

     On September 30, 1994, the Company purchased for $35 million in cash the
assets of Brazos Gas Compressing Company, a subsidiary of Mitchell Energy &
Development Corporation. On November 30, 1994, the Company purchased the
natural gas compression assets of Halliburton Company using $55 million of
available cash and borrowings of $150 million. The costs of these acquisitions
were allocated under the purchase method of accounting based on the fair value
of the assets acquired. In connection with the purchase of the natural gas
compression assets of Halliburton Company, goodwill of approximately $25
million was recorded as other assets in the Consolidated Balance Sheet and is
being amortized in equal charges to earnings over a 15-year period.

     The results of Brazos' and Halliburton's operations have been
consolidated with the Company's effective October 1, 1994, and December 1,
1994, respectively. Pro forma combined results of operations of the Company
and of Brazos and Halliburton, including appropriate purchase accounting
adjustments for the years ended March 31, 1994 and 1995 and the six months
ended September 30, 1994, as though the acquisition had taken place on April 1
of the respective periods, are as follows:

     In March 1993, the Company sold its 70% interest in the net assets of the
Container Shipping segment to the minority-interest owner. The Consolidated
Statement of Earnings for the year ended March 31, 1993 reports separately the
results of continuing operations and the discontinued Container Shipping
segment. The results of the discontinued Container Shipping segment for the
year ended March 31, 1993, which are presented as a net amount in the
Consolidated Statements of Earnings, consist of revenues of $66.6 million,

     The actual income tax expense attributable to earnings from continuing
operations for the years ended March 31, 1993, 1994 and 1995 differed from the
amounts computed by applying the U.S. federal tax rate of 34% in fiscal 1993
and 35% in fiscal 1994 and 1995 to pre-tax earnings from continuing operations
as a result of the following:

     The net changes in the valuation allowance for the years ended March 31,
1994 and 1995 were increases of $184,000 and $3,016,000, respectively. These
changes were made to provide for uncertainties surrounding the realization of
certain foreign net operating loss carryforwards. The remaining balance of the
deferred tax assets should be realized through future operating results and
the reversal of taxable temporary differences.

     At March 31, 1995, the Company had investment tax credit carryforwards
for federal income tax purposes of approximately $5,842,000, which are
available to reduce future federal income tax through 2002. In addition, the
Company has alternative minimum tax credit carryforwards of approximately
$3,007,000, which are available to reduce future federal regular income taxes
over an indefinite period.

     The Company has not recognized a deferred tax liability of approximately
$30,100,000 for the undistributed earnings of certain foreign subsidiaries
that arose in prior years because the Company currently does not expect those
unremitted earnings to reverse and become taxable to the Company in the
foreseeable future. A deferred tax liability will be recognized when the
Company expects that it will realize those undistributed earnings in a taxable
manner, such as through receipt of dividends or sale of investments. As of
March 31, 1995 the undistributed earnings of these subsidiaries were
approximately $86,000,000.

                                       =========  ===========

     The Company's revolving credit and term loan agreement (the "agreement")
consists of a $130 million revolving credit facility and a $120 million term
loan facility. At March 31, 1995 there were $12 million of borrowings
outstanding under the revolving credit facility and $100 million of borrowings
outstanding under the term loan facility.

     The agreement bears interest, at the Company's option, at prime rates
plus .375% or LIBO rates plus 1.25% or 1.50% (7.74% at March 31, 1995). The
lower LIBO rate is available as long as the Company maintains an investment
grade senior debt rating from Moody's Investor Services, Inc. and Standard &
Poor's. Effective April 10, 1995, the interest rate was reduced to prime or
LIBO plus .875%.

     The revolving credit commitment of $130 million expires on September 30,
1996, at which time the then outstanding balance may be converted to a term
loan repayable in 16 quarterly installments beginning December 31, 1996.
Borrowings under the term loan facility are payable in 27 quarterly
installments of $3 million commencing March 31, 1995, with the remaining loan
balance due December 31, 2001. All of the borrowings under the agreement are
unsecured and the Company pays an annual fee of from .250% to .375% on the
unused portion of the revolving credit facility.

     Under the terms of the agreement, the Company has agreed to certain
requirements and limitations, including: limitations on the payment of
dividends on common stock, investments and aggregate indebtedness; a minimum
level of tangible net worth of $425 million plus 30% of cumulative net
earnings, as defined, after March 31, 1993 (total $445,300,000 at March 31,
1995); and a minimum ratio of current assets to current liabilities of 1.5 to
1. The agreement also prohibits the Company from encumbering its assets, other
than assets already encumbered at November 30, 1994, for the benefit of
others.

     During the second quarter of fiscal 1994 approximately $51 million of
notes were retired prior to maturity using available cash. The retirement
resulted in an after-tax extraordinary charge to earnings of approximately
$4,450,000, or $.08 per common share. The extraordinary charge to earnings
consisted of a $6,500,000 prepayment penalty and the write-off of deferred
finance costs of $370,000, less $2,420,000 of income tax benefits associated
with the retired debt.

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     On March 16, 1994, the Company called for redemption of its 7%
convertible subordinated debentures due 2010. Holders converted $1,113,000 of
debentures into 44,520 shares of the Company's common stock at a conversion
price of $25.00 per share. The remainder of the debentures were redeemed at
101.4% of par value plus accrued interest on April 18, 1994. The debentures,
along with the prepayment premium, are included in current liabilities at
March 31, 1994. The redemption resulted in an after-tax extraordinary charge
to earnings of approximately $7,520,000, or $.14 per common share in the
fourth quarter of fiscal 1994. The extraordinary charge to earnings consisted
of a $644,000 prepayment premium and the write-off of unamortized original
issue discount and deferred finance costs of $10,926,000, less $4,050,000 of
income tax benefits.

     Based on current interest rates offered to the Company for borrowings
with maturities similar to the remainder of its long-term debt, total
long-term debt at March 31, 1995 approximates the fair value of the debt.

(8)  BENEFIT PLANS

     Upon meeting various citizenship, age and service requirements, employees
are eligible to participate in a defined contribution savings plan. The plan
held 537,525 shares and 536,804 shares of the Company's common stock at March
31, 1994 and 1995, respectively. Amounts charged to expense for the plan for
1993, 1994 and 1995 were $1,193,000, $1,282,000, and $951,000, respectively.

     A defined benefit pension plan covers substantially all U.S. citizen
employees and employees who are permanent residents of the United States.
Benefits are based on years of service and employee compensation. The Company
also has a supplemental retirement plan (Supplemental Plan) that provides
pension benefits to certain employees in excess of those allowed under the
Company's tax qualified pension plan. Certain benefits programs are maintained
in several other countries which provide retirement income for covered
employees.

     Net periodic pension cost for the U.S. defined benefit pension plan and
the Supplemental Plan for 1993, 1994 and 1995 include the following
components:

                                         1993       1994       1995

     Qualified retired employees currently are covered by a program which
provides limited health care and life insurance benefits. Costs of the program
are based on actuarially determined amounts and are accrued over the period
from the date of hire to the full eligibility date of employees who are
expected to qualify for these benefits.

     Pursuant to the April 1, 1992 adoption of Statement of Financial
Accounting Standards No. 106, "Employers Accounting for Postretirement
Benefits Other Than Pensions," the Company recognized during fiscal 1993 the
full amount of its accumulated postretirement benefit obligation of
$10,061,000 less income tax benefits of $3,421,000, which amounts are included
in the fiscal 1993 Consolidated Statement of Earnings as the cumulative effect
of an accounting change. The accumulated postretirement benefit obligation
amount represents the present value at April 1, 1992 of the estimated future
benefits payable to current retirees and a pro rata portion of the estimated
benefits payable to active employees after retirement.

     Net periodic postretirement health care and life insurance costs for
1993, 1994 and 1995 include the following components:

     The assumed health care cost trend rate used in measuring the accumulated
postretirement benefit obligation will be 13% in 1996, gradually declining to
6.5% in the year 2002 and thereafter. A 1% change in the assumed health care
cost trend rates for each year would change the accumulated postretirement
benefit obligation by approximately $1,500,000 at March 31, 1995 and change
the cost for the year ended March 31, 1995 by $392,000. The assumed discount
rates used in determining the accumulated postretirement benefit obligation
were 7.25% in 1994 and 8.5% in 1995.

(10)  CAPITAL STOCK

     Under the Company's stock option and restricted stock plans, the
Compensation Committee of the Board of Directors has authority to grant stock
options and restricted shares of the Company's stock to officers and other key
employees. At March 31, 1995, 2,814,623 shares of common stock are reserved
for issuance under the plans. The stock option price and exercise period are
set by the grant, with the price equal to the market price of the stock on the
date of grant.

                                        ============   ===========

     At March 31, 1994 and 1995, 522,205 shares and 531,403 shares,
respectively, were exercisable under the stock option plans.

     The restricted stock plan permits the grant of Company shares restricted
as to transferability and subject to a substantial risk of forfeiture. The
vesting restrictions and period during which the transferability restrictions
are applicable are determined on a case-by-case basis. During the restricted
period, the restricted shares may not be transferred or encumbered but the
recipient has the right to vote and receive dividends on the restricted
shares. At March 31, 1995, contingent awards totalling 36,498 restricted
Company shares were outstanding, to be issued in conjunction with and as a
result of the exercise of certain stock options. None of these restricted
shares were issued as of March 31, 1995. Once these restricted shares are
issued, they would be forfeited if, during the five years after issuance, a
disposition was made of the option shares, except for dispositions
specifically permitted by the grant. The ownership of these restricted shares
will vest at the end of the five year period in which they are subject to
forfeiture.

     In accordance with an employment agreement with the Company's chairman of
the board, 70,000 shares of restricted common stock of the Company were
granted to him on October 20, 1994. These restricted shares vest at varying
intervals when the average sales price of the common stock reaches certain
predetermined levels. The fair market value of the stock at the time of the
grant was classified in stockholders' equity as deferred
compensation-restricted stock and will be amortized by equal monthly charges
to earnings over approximately seven years.

     During fiscal 1994, all then-existing treasury shares were cancelled and,
accordingly, the amount of treasury shares were reclassified to common stock
and additional paid-in capital.

     At March 31, 1994 and 1995, 3,000,000 shares of no par value preferred
stock were authorized and unissued.

     Under a Shareholder Rights Plan, one preferred stock purchase right has
been distributed as a dividend for each outstanding common share. Each right
entitles the holder to purchase, under certain conditions, one two-hundredth
of a share of Series A Participating Preferred Stock at an exercise price of
$50, subject to adjustment. The rights will not be exercisable unless a person
(as defined in the plan) acquires beneficial ownership of 16% or more of the
outstanding common shares, or a person

          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
commences a tender offer or exchange offer, which upon its consummation such
person would beneficially own 16% or more of the outstanding common shares.

     If after the rights become exercisable a person becomes the beneficial
owner of 16% or more of the outstanding common shares (except pursuant to an
offer for all shares approved by the Board of Directors), each holder (other
than the acquirer) will be entitled to receive, upon exercise, common shares
having a market value of twice the exercise price. In addition, if the Company
is involved in a merger (other than a merger which follows an offer for all
shares approved by the Board of Directors), major sale of assets or other
business combination, each holder of a right (other than the acquirer) will be
entitled to receive, upon exercise, common stock of the acquiring company
having a market value of twice the exercise price.

     The rights may be redeemed for $.01 per right at any time prior to ten
days following the acquisition by a person of 16% or more of the outstanding
common shares. The rights expire on May 1, 2000.

(11)  COMMITMENTS AND OTHER MATTERS

     An employment agreement exists with the Company's chairman of the board,
president and chief executive officer whereby he will serve in such capacity
through December 31, 1997. The terms of the employment agreement provide for
an annual base salary and certain other benefits. Compensation continuation
agreements exist with all other officers and certain other key employees of
Tidewater Inc. whereby each receives compensation and benefits in the event
that his or her employment is terminated following certain events relating to
a change in control of the Company. The maximum amount of compensation that
could be paid under the agreements, based on present salary levels, is
approximately $5,400,000. The amount that could be paid for certain benefits
is not presently determinable.

     In March 1993 the Company requested that the Company's then chairman of
the board, president and chief executive officer amend his then existing
employment and consulting agreement. For its benefit, the Company elected to
amend the agreement in view of possible changes to tax laws then under
consideration by the Clinton administration and Congress. The amendment
accelerated the vesting of all outstanding shares of restricted stock such
that these shares became fully vested and freely transferable immediately. The
original terms of the restricted stock shares included restrictions during the
employment term of the agreement. Due to the acceleration of the vesting of
the restricted stock shares on March 31, 1993, the then remaining deferred
compensation of $2,850,000 was charged to other expenses in the Consolidated
Statement of Earnings for fiscal 1993. The amendment also provided for an
immediate lump-sum distribution of the present value of benefits under the
Company's supplemental retirement plan, including the additional benefits that
would have accrued assuming he remained employed by the Company through
September 24, 1994. The lump-sum distribution amounted to $2,212,000 and
included $921,000 for unaccrued benefits which was charged to other expenses
in the Consolidated Statement of Earnings for fiscal 1993.

     During the fourth quarter of fiscal 1995, the Company recorded as "other
expense" $5.9 million ($3.7 million after tax, or $.07 per common share) for
the cost of a restructuring program of its corporate headquarters and
worldwide marine operations which was designed to reduce costs and improve
operating efficiencies. Substantially all of the costs associated with the
restructuring program were paid before March 31, 1995. The restructuring
resulted in the elimination of approximately 150 positions, realignment of
duties and responsibilities and streamlining of administrative functions. The
charge reflects the costs associated with staff reductions, relocations and
related transition expenses.

     During the third quarter of fiscal 1995, the Company recorded as "other
expense" a charge of $2.5 million ($1.6 million after tax, or $.03 per common
share) for reserves to cover possible losses due to the potential insolvency
of certain of the Company's insurers.

                       TIDEWATER INC. AND SUBSIDIARIES
          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In 1983, the Environmental Protection Agency (EPA) notified two
subsidiaries of the Company that they were among 53 potentially responsible
parties (PRP's) for cleanup costs at the Western Sand and Gravel site in Rhode
Island. In 1989, the EPA notified another subsidiary of the Company that it
was a PRP for cleanup costs at a National Priorities List site. EPA later
nominated the subsidiary a de minimis participant for this site. Based on its
evaluation of potential total clean-up costs, its estimate of its potential
exposure, and the viability of other PRP's, management believes that any costs
ultimately required to be borne by the Company at these sites will not have a
material adverse effect on its results of operations, cash flow or financial
position.

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

(12)  BUSINESS SEGMENTS AND GEOGRAPHIC DISTRIBUTION OF OPERATIONS

     The Company operates principally in two business segments. Tidewater
Marine provides support services to the offshore oil and gas industry, and
Tidewater Compression provides the energy industry with engineered products
and services used primarily in oil and gas production, enhanced recovery,

the Company's management; our responsibility is to express an opinion on these

                       HORNBECK OFFSHORE SERVICES, INC.
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 -- BUSINESS AND SUMMARY OF ACCOUNTING POLICIES:

ORGANIZATION AND HISTORY

     Hornbeck Offshore Services, Inc. was incorporated under the laws of the
state of Delaware in January 1981. All references to the "Company" refer to
Hornbeck Offshore Services, Inc. and its subsidiaries unless the context
requires otherwise.

     The Company is engaged in the worldwide offshore marine services
business, primarily serving the oil and gas industry through its operation and
management of a diversified fleet of 63 vessels (the "vessels"). The fleet
consists of supply, tug-supply, crew and specialty vessels; 57 of the vessels
are owned, 4 are chartered and 2 are managed for unrelated parties.
Additionally, the Company maintains a 49.9% equity interest in 3 entities
which operate and own or lease a combined fleet of 29 safety standby vessels.

CONSOLIDATED FINANCIAL STATEMENTS

     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiaries. The equity method of accounting is used
when the Company has a 20%-50% interest in an affiliate. Under the equity
method, original investments are recorded at cost and are adjusted by the
Company's share of earnings or losses. All significant intercompany accounts
and transactions have been eliminated. Any difference between the Company's
share of book value of an equity affiliate and its investment amount is
amortized over the remaining useful life of the underlying assets.

MARKETABLE SECURITIES

     Marketable securities are stated at market value which approximates cost
and consist of U.S. Government or Agency issues or mutual funds that invest in
the same type of securities. The cost of marketable securities at December 31,
1993 approximated $27,505,000.

REVENUE AND EXPENSE RECOGNITION

     Charter revenue is earned and recognized on a daily rate basis. The
Company's accounts receivable are generally unsecured and are due primarily
from companies involved in exploration and production of oil and gas reserves.
Operating and other costs are expensed as incurred.

PROPERTY AND EQUIPMENT

     For financial reporting purposes, the Company records depreciation
expense using the straight-line method over the estimated useful lives of the
related assets. For tax purposes, depreciation is computed using accelerated
methods.

     The net book value of the Company's vessels is reviewed periodically to
determine that their recorded value does not exceed the estimated future
benefit from utilization of those vessels.

OTHER ASSETS

     Other assets consist primarily of drydocking expenditures. Drydocking
expenditures are capitalized and amortized on a straight-line basis over the
period to be benefitted (generally 24 to 36 months).

DEFERRED INCOME TAXES

     Deferred income taxes are determined utilizing a liability approach. This
method gives consideration to the future tax consequences associated with
differences between financial accounting and tax bases of assets and
liabilities. Such differences relate mainly to depreciable assets. This method
gives immediate effect to changes in income tax laws upon enactment. The
income statement effect is derived from changes in deferred income taxes on
the balance sheet. Adoption of Statement of

<PAGE>
                       HORNBECK OFFSHORE SERVICES, INC.
          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
Financial Accounting Standard No. 109, "Accounting for Income Taxes," in 1993
did not have a significant impact on the Company's financial statements.

EARNINGS PER SHARE

     Earnings per share is calculated using the weighted-average number of
shares outstanding assuming exercise of dilutive stock options and conversion
of preferred stock. The weighted-average number of primary shares, which
includes common shares and equivalent common shares outstanding, during the
years ended December 31, 1992, 1993 and 1994 was 8,842,000, 11,901,000 and
13,460,000, respectively and, during the nine-month periods ended September
30, 1994 and 1995 were 13,479,000 and 13,352,000, respectively. Fully diluted
shares are the same as primary shares.

CASH AND EQUIVALENTS

     For purposes of the consolidated statement of cash flows, the Company
considers all deposits readily convertible to known amounts of cash with
original maturities of three months or less to be cash and equivalents. For
the year ended December 31, 1994, included in "Interest and other income," is
interest income of $1,173,000 from such deposits.

RECLASSIFICATIONS

     Certain 1992 and 1993 amounts were reclassified to conform to the 1994
presentation.

UNAUDITED INTERIM FINANCIAL INFORMATION

     The unaudited consolidated balance sheet as of September 30, 1995, the
consolidated statements of income for the nine months ended September 30, 1994
and September 30, 1995 and the consolidated statements of cash flows for the
nine months ended September 30, 1994 and September 30, 1995 have been prepared
by the Company, without audit. In the opinion of management, all adjustments
(which include only normal recurring adjustments) necessary to present fairly
the financial position, results of operations and cash flows at September 30,
1995 and for all periods presented have been made.

NOTE 2 -- ACQUISITIONS AND DISPOSITIONS OF BUSINESSES AND VESSELS:

     On November 30, 1994, the Company acquired an equity interest in Seaboard
Holdings Limited (Note 4). On November 15, 1994, the Company completed the
acquisition of 13 supply vessels from Oil and Gas Rental Services, Inc. ("Oil
& Gas") for cash consideration of $46 million. The Company borrowed $23
million in connection with this acquisition (Note 5).

     On July 23, 1993, the Company acquired an equity interest in Ravensworth
Investments Limited ("Ravensworth"), and the Company's share of earnings of
this affiliate has been included in the Company's results of operations since
that date (Note 4). On April 29, 1993, the Company sold two vessels previously
being operated in the North Sea to an unrelated entity for approximately $1.3
million, which approximated the carrying value of the vessels. On June 17,
1993, the Company purchased a supply vessel for cash payment of $1,175,000.

     On November 19, 1992, the Company completed the acquisition of 20
offshore supply vessels and one utility vessel from Petrol Marine Corporation,
Portal Energy Corporation and Pentad Offshore Corporation (collectively, the
"Sellers" or "Petrol") for aggregate consideration of $18,500,000. The
aggregate consideration paid to the Sellers consisted of $4,750,000 in cash,
$5,250,000 of unsecured notes issued by the Company and 1,365,462 restricted
shares of the Company's $.10 par value common stock valued at $8,500,000. As a
condition of the transaction, $2,000,000 of the cash consideration was
escrowed for purposes of refurbishing and recertifying seven of the acquired
vessels which were not in service on the acquisition date. These vessels have
been repaired and refurbished utilizing all of the escrow funds. Since
escrowed funds were insufficient to pay for the required work

                       HORNBECK OFFSHORE SERVICES, INC.
          NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
on the seven vessels, the future debt service owed to the Sellers was reduced
by $1,794,000. The remaining acquisition debt has been repaid.

     The results of operations of the acquired vessels are included in the
consolidated financial statements from the respective acquisition dates of
November 19, 1992 for the Petrol acquisition and from November 15, 1994 for
the Oil & Gas acquisition. Substantially all of the purchase price was
allocated to vessels acquired based on their fair market values and the
transactions have been accounted for using the purchase method. The acquired
vessels were employed prior to the acquisitions and continue to be employed by
the Company after the closing of the acquisitions in the offshore marine
service business, primarily serving the oil and gas industry.

     Assuming the Oil & Gas transaction occurred at the beginning of each year
presented and the Ravensworth transaction occurred at the beginning of 1993,
condensed unaudited pro forma combined results of operations are as follows:

assets, which included vessels and reserve funds in the amount of $2,518,000,
and reduced debt by $2,563,000. The partnerships' debt was nonrecourse with
respect to the Company. No significant gain or loss was recognized by the
Company as a result of these transactions and no significant partnership
assets existed at December 31, 1992.

NOTE 4 -- INVESTMENTS IN AFFILIATES:

     On November 30, 1994, the Company acquired 49.9% of the equity interests
of Seaboard Offshore Group Limited, a Scottish corporation ("Seaboard"). The
transaction was accounted for using the purchase method of accounting. At the
time of the transaction, Seaboard owned a fleet of six safety standby vessels
operating in the North Sea. Consideration in the form of a guarantee of
approximately $483,000 of certain Seaboard indebtedness was given. Further,
the Company funded a loan totaling 1.5 million ($2.35 million) to Seaboard for
operational purposes and has recorded a note receivable from affiliate which
bears interest at LIBOR plus 1 3/4% and is payable in 32 equal monthly
installments. This note receivable is unsecured, but 50% of the balance is
guaranteed by Ravensworth Holdings Limited ("RHL"), the owner of a 50.1%
interest in Seaboard and Ravensworth. The Company accounts for its investment
in Seaboard using the equity method of accounting.

     In connection with the Seaboard acquisition, the Company was granted an
option by RHL to acquire the remaining outstanding equity interest in
Seaboard. Exercise of the option is contingent upon the Company's exercise, in
full, of the options to acquire the remaining capital stock of Ravensworth, as
discussed below.

     On July 23, 1993, the Company acquired 49.9% of the outstanding capital
stock of Ravensworth from RHL, the owner of the outstanding capital stock of
Ravensworth, for a purchase price of $11 million in cash and approximately
$2.7 million in the form of 158,978 shares of restricted Common Stock
("Ravensworth Acquisition"). Ravensworth owned or chartered a fleet of
twenty-two (22) safety standby vessels operating in the North Sea at the time
of the acquisition. The Company accounts for its investment in Ravensworth
using the equity method of accounting. The difference between the Company's
investment in Ravensworth and its proportionate share of Ravensworth's book
equity totaled $9,012,000 at December 31, 1994 and this difference is being
depreciated over the remaining useful life of the Ravensworth fleet. The
Company used the purchase method of accounting for this transaction.

     In connection with the Ravensworth Acquisition, the Company acquired
options to purchase the remaining outstanding capital stock of Ravensworth,
exercisable after January 1, 1995 in two equal annual installments, with the
first option exercisable on or before March 31, 1996 (the "1995 Option") and
the second option exercisable on or before March 31, 1997 (the "1996 Option").
The Company may, at its election, accelerate the exercise of the 1996 Option
to any date on or after January 1, 1995. The 1996 Option will expire unless
the 1995 Option is exercised in full. The consideration payable upon exercise
of the 1995 Option and the 1996 Option is to be paid one-third in cash and
two-thirds in

common stock of the Company valued at market price, as defined in the
applicable agreements. The Company may elect to pay in U.S. dollars any
payments that would otherwise be made to RHL in the Company's common stock.

     The per share consideration to be paid for the remainder of Ravensworth
(subject to the adjustment described below) will be equal to the per share
price paid by the Company for the initial 49.9% investment, plus simple
interest at 7% (compounded annually) from the closing of the initial
acquisition to the date of payment. The consideration for Ravensworth will be
adjusted by 50% of any difference in actual Ravensworth and Seaboard earnings
before depreciation, interest and taxes ("EBDIT") versus a target EBDIT for
1994 and 1995, and by 25% of such difference for 1996. The maximum adjustment
to the consideration paid or payable for Ravensworth with respect to any year
for which EBDIT is measured against a specified target is limited to $4
million. In the event the Company does not exercise either of the options to
acquire additional interests in Ravensworth, the agreement calls for certain
purchase/sale arrangements between the parties with respect to Ravensworth.

     In connection with the Company's initial purchase of 49.9% at
Ravensworth, approximately 106,000 shares of the Company's common stock placed
in escrow at the time of acquisition were returned to the Company based on
Ravensworth's actual EBDIT for 1994 compared to targeted EBDIT as described
under the agreement. Such shares, valued at approximately $1.8 million, were
cancelled and stockholders' equity and Ravensworth's investment accounts were
reduced accordingly.

     Summarized historical, combined financial information for the affiliated
investees, which includes Ravensworth as of and for the years ended December
31, 1993 and 1994 and Seaboard as of and for the one month ended December 31,

1998 -- $3,433,000 and 1999 -- $9,081,000.

     Concurrent with the November 15, 1994 Oil & Gas vessel acquisition, the
Company entered into a $20 million term loan and a $10 million revolving
credit facility with a bank. Any borrowings under the revolving credit
facility will be due and payable on November 15, 1997. The availability of the
revolving credit facility is based on specified trade receivables levels and
will be reduced by outstanding letters of credit. At December 31, 1994 and
September 30, 1995, there were no outstanding balances under the revolving
credit facility.

     At the Company's option, interest with respect to any amounts outstanding
under the revolving credit facility and the bank term loan accrues at a rate
equal to the lender's prime rate, or the LIBOR rate plus 1%, and is payable
quarterly. The indebtedness is collateralized by 13 vessels owned by
subsidiaries of the Company. The indebtedness also contains covenants which,
among other things, provide limitations on the sale of such vessels and
require the Company to maintain certain financial ratios and minimum net
worth.

     The U.S. Government Guaranteed Ship Financing Bonds represent several
series of bonds which are guaranteed by MARAD. These bonds mature from
2000-2002 and bear interest at rates ranging from 8.75% to 10.75%. Through
December 31, 1994, the Company had deposited $1,280,000 into the reserve. The
Company expects to deposit approximately $250,000 in 1995.

     The Company's effective tax rate approximated the statutory rate to which
it was subject in 1992. The deferred income tax liability is primarily
comprised of differences in the tax and book basis of the Company's vessels
and benefits from the carryforward tax attributes as described below.

     Undistributed earnings of the Company's foreign affiliates aggregated
$2,589,000 on December 31, 1994, which, under existing law, will not be
subject to U.S. tax until distributed as dividends. Since the earnings have
been and are intended to be indefinitely reinvested in foreign operations, no
provision has been made for any U.S. taxes that may be applicable thereto. The
amount of unrecognized deferred U.S. taxes on these undistributed earnings is
approximately $760,000. Furthermore, any taxes paid to foreign governments on
those earnings may be used in whole or in part, as credits against the U.S.
tax on any dividends distributed from such earnings.

     As of December 31, 1994, the Company has net operating loss carryforwards
of $347,000 which will expire from 2004 to 2005 if not used to offset future
taxable income. As of December 31, 1994, the Company has investment tax credit
carryforwards of $1,006,000 which will expire in 1997, if not

     The stock options are exercisable over a five-year or ten-year period
which commences on the date of grant. The number of shares exercisable in each
year during the period is determined by the Company's Board of Directors (or
compensation committee) at the time of grant. At December 31, 1992, 1993 and
1994, options to purchase 264,300, 246,739 and 257,763 shares, respectively,
were exercisable. Because the exercise price of the options equaled the market
price of the Company's stock on the dates the options were granted, no
compensation costs have been recognized by the Company.

     Effective January 1, 1993, a total of 13,975 shares were awarded to
employees which vest over two years. Compensation expense of approximately
$97,000 will be recorded for the stock awards over the vesting period. On

vest over three years. Compensation expense of approximately $170,000 will be
recorded for the stock awards over the vesting period.

     In November 1994, a total of 2,698 shares which vest over a period of
1 1/2-2 years were awarded to employees. Compensation expense of approximately
$37,845 will be recorded for the stock awards over the vesting period.

     In 1992, 1993 and 1994, shares totaling 3,500, 3,500 and 4,200,
respectively, were awarded to the Company's Board of Directors.

     No stock appreciation rights have been awarded under the Employee
Incentive Plans. The Company has no postretirement benefits that are required
to be accrued under Statement of Financial Accounting Standards ("SFAS") No.

NOTE 11 -- COMMITMENTS AND CONTINGENCIES:

     Hornbeck has received and is responding to a subpoena for documents from
the United States District Court for the Southern District of Texas, Houston
Division. The scope of the subpoena suggests an interest in Hornbeck's
compliance with certain environmental statutes and regulations, violations of
which could carry both civil and criminal liabilities. The subpoena seeks
information concerning Hornbeck's vessels since January 1, 1993 regarding
vessel operations as they relate to the purchase, use and disposition of
petroleum and related products.

     It is Hornbeck's policy to comply with all applicable laws, including
laws designed to protect the environment. While management and the Hornbeck
Board do not believe that any outcome of the investigation would have a
material adverse effect on the financial position of Hornbeck, they cannot
predict the nature or ultimate outcome of the investigation or any proceeding
that might be based thereon.

     The Company is not party to any legal proceedings the result of which
could, in the opinion of management, have a material adverse effect upon the
Company.

NOTE 14 -- SUBSEQUENT EVENTS (UNAUDITED):

     On December 21, 1995, Hornbeck Offshore Services, Inc. ("Hornbeck")
entered into an Agreement and Plan of Merger with Tidewater Inc. ("Tidewater")
to merge a wholly owned subsidiary of Tidewater into Hornbeck with Hornbeck
becoming a wholly owned subsidiary of Tidewater. The merger will be structured
as a tax free exchange of approximately 8,780,000 Tidewater shares for all
Hornbeck shares (an exchange ratio of 0.667 Tidewater shares for each Hornbeck
share, subject to adjustment) and will be accounted for as a pooling of
interests.

     The Board of Directors of both Hornbeck and Tidewater have approved the
combination subject to the approval of stockholders of Hornbeck holding at
least 66 2/3% of the outstanding Hornbeck common stock, certain regulatory
approvals and certain other conditions. The merger is expected to be completed
in early 1996. Upon consummation of the merger, Larry D. Hornbeck will join
the Board of Directors of Tidewater and will become a consultant to Tidewater.

     On December 29, 1995, Hornbeck made advance payments in the approximate
aggregate amount of $2,500,000 to three executive officers, such payments
being a portion of the amounts to which such officers would become entitled
following consummation of the merger under the terms of change in control
agreements between Hornbeck and such executive officers.

  of incorporation  and  by-laws,  as  amended  or  restated
  through  the date of this Agreement and the organizational
  documents  governing  each  member  of  the Hornbeck Group
  listed on Schedule 4.2.  The minute books  of  each member
  of  the  Hornbeck Consolidated Group, and to the Knowledge
  of Hornbeck,  the minute books of each member of the North
  Sea  Group,  contain   reasonably  complete  and  accurate
  records of all corporate  actions  of the equity owners of
  the  various entities and of the boards  of  directors  or
  other  governing  bodies,  including  committees  of  such
  boards or governing bodies.  The stock transfer records of

  registrar  and, to  the  Knowledge  of  Hornbeck,  contain
  complete  and   accurate  records  of  all  issuances  and
  redemptions of stock  by Hornbeck.  Except as set forth on
  Schedule 4.6, neither Hornbeck  nor,  to  the Knowledge of
  Hornbeck,  any  of  its  Affiliates,  is  a party  to  any
  agreement  with respect to the capital stock  of  Hornbeck
  other than this Agreement.

       Section 4.7  SEC  Documents;   Financial  Statements;
  Liabilities.   (a)   Hornbeck   has   filed  all  required
  reports, schedules, forms, statements and  other documents
  with  the  SEC  since  January 1, 1992 (the "Hornbeck  SEC
  Documents").  The Hornbeck  SEC  Documents,  and  any such
  reports,  forms  and documents filed by Hornbeck with  the
  SEC after the date  hereof,  as amended, complied, or will
  comply,  as  to  form in all material  respects  with  the
  requirements of the Securities Act or the Exchange Act, as
  the case may be, and  the rules and regulations of the SEC
  promulgated thereunder  applicable  to  such  Hornbeck SEC
  Documents,   and   none  of  the  Hornbeck  SEC  Documents
  contained  or will contain,  any  untrue  statement  of  a
  material fact or omitted to state a material fact required
  to be stated  therein  or  necessary  in order to make the
  statements  therein,  in light of the circumstances  under
  which  they  were made, not  misleading.   Except  to  the
  extent that information  contained  in  any  Hornbeck  SEC
  Document has been superseded by a later filed Hornbeck SEC
  Document,  none of the Hornbeck SEC Documents contains any
  untrue statement  of a material fact or omits to state any
  material fact required  to  be stated therein or necessary
  in order to make the statements  therein,  in light of the
  circumstances under which they were made, not misleading.

            (b)   The Hornbeck Financial Statements included
  in the Hornbeck SEC Documents have been audited  by  Price
  Waterhouse  LLP,  independent  accountants (in the case of
  the Hornbeck Audited Financial Statements)  in  accordance
  with  generally  accepted  auditing  standards, have  been
  prepared  in  accordance  with  United  States   generally
  accepted   accounting   principles   applied  on  a  basis
  consistent  with  prior  periods, and present  fairly  the
  financial  position of Hornbeck  at  such  dates  and  the
  results of operations  and cash flows for the periods then
  ended,  except,  in  the  case  of  the  Hornbeck  Interim
  Financial  Statements,  as  permitted  by  Rule  10-01  of
  Regulation S-X of the SEC.  The Hornbeck Interim Financial
  Statements  reflect all adjustments  (consisting  only  of
  normal, recurring  adjustments)  that  are necessary for a
  fair  statement  of  the  results for the interim  periods
  presented  therein.   Except  as  set  forth  on  Schedule
  4.7(b), no member of the  Hornbeck Consolidated Group has,
  nor are any of their respective  assets  subject  to,  any
  liability,  commitment,  debt  or  obligation (of any kind
  whatsoever whether absolute or contingent, accrued, fixed,
  known,   unknown,  matured  or  unmatured)   ("Undisclosed
  Liabilities"),  except  (i) as and to the extent reflected
  on the Hornbeck Latest Balance  Sheet, or (ii) as may have
  been incurred or may have arisen  since  the  date  of the
  Hornbeck  Latest  Balance Sheet in the ordinary course  of
  business and that are  not material individually or in the
  aggregate or are permitted by this Agreement.

            (c)   The Hornbeck Latest Balance Sheet includes
  appropriate reserves for  all  Taxes and other liabilities
  incurred as of such date but not yet payable.

            (d)   Since  the  date of  the  Hornbeck  Latest
  Balance Sheet, there has been no change that has had or is
  likely to have a Material Adverse Effect on Hornbeck.

            (e)   The statements  of  income included in the
  Hornbeck Financial Statements do not contain any income or
  revenue   realized   from  services  that  the   Surviving
  Corporation  would  be  prohibited   or   restricted  from
  offering after the Effective Time pursuant to any covenant
  or provision in any material contract to which  any member
  of the Hornbeck Consolidated Group is a party.

            (f)   Hornbeck's  investment  in  the North  Sea
  Group  is  recorded  on  the Hornbeck Financial Statements
  under the equity method of accounting.  Attached hereto as
  Schedule 4.7(f) is a balance sheet reflecting the combined
  operations of the North Sea Group as of September 30, 1995
  (the  "North Sea Group Latest  Balance  Sheet").   To  the
  Knowledge  of  Hornbeck,  except as reflected on the North
  Sea Group Latest Balance Sheet, no member of the North Sea
  Group has, nor are any of its  respective  assets  subject
  to,  any  indebtedness  for  borrowed money, except as may
  have been incurred or may have  arisen  since  the date of
  the  North Sea Group Latest Balance Sheet in the  ordinary
  course  of  business.   Except  as  set  forth on Schedule
  4.7(f),  there  is  no  liability,  commitment,   debt  or
  obligation  (of  any  kind whatsoever whether absolute  or
  contingent, accrued, fixed,  known,  unknown,  matured  or
  unmatured)  of  the  North  Sea  Group  which is, or could
  reasonably be expected to become, a liability, commitment,
  debt  or  other  obligation  of the Hornbeck  Consolidated
  Group.

       Section 4.8  Accounts Receivable. All of the accounts
  receivable reflected on the Hornbeck Latest  Balance Sheet
  or  created  thereafter  have  arisen only from bona  fide
  transactions in the ordinary course of business, represent
  valid obligations owing to Hornbeck  or  another member of
  the Hornbeck Consolidated Group and have been  accrued and
  recorded   in  accordance  with  United  States  generally
  accepted accounting  principles.   Except  as set forth on
  Schedule  4.8, such accounts receivable either  have  been
  collected in full or will be collectible in full when due,
  without any  counterclaims, set-offs or other defenses and
  without provision  for  any  allowance  for  uncollectible
  accounts  other  than  such  allowance as appears  on  the
  Hornbeck Latest Balance Sheet.

  breached any of the terms or  conditions  of  any  of  its
  material  agreements, contracts or commitments, and to the
  Knowledge  of   Hornbeck,   no   other   parties  to  such

  in the conduct of its business,  good  and  valid title to
  all  real  property  and  all other properties and  assets
  reflected in the Hornbeck Latest  Balance  Sheet  and  the

  Liens,  except for (i) Liens that secure indebtedness that
  is properly reflected in the Hornbeck Latest Balance Sheet
  or the North  Sea  Group  Latest Balance Sheet; (ii) Liens
  for  Taxes accrued but not yet  payable;  (iii)  Permitted

  obligations collateralized by any such contested Permitted
  Liens  in  the  aggregate  exceed   $150,000;   (iv)  such
  imperfections of title and encumbrances, if any, as do not
  materially  detract from the value or materially interfere
  with the present  use  of any such properties or assets or
  the potential sale of any  such  properties and assets and
  (v) capital leases and leases of such  properties, if any,
  to  third  parties  for  fair  and adequate consideration.
  Schedule 4.11(a) contains a list  of all Liens (other than
  Permitted   Liens)   on   property  other   than   vessels
  collateralizing  indebtedness   on   the  Hornbeck  Latest
  Balance  Sheet  and any guaranty or other  credit  support
  arrangement pursuant  to  which any member of the Hornbeck
  Consolidated Group has guaranteed  an  obligation  of  any
  other  member  of  the  Hornbeck  Consolidated Group where
  assets other than vessels are the collateral.   There  are
  no  guaranty or other credit support arrangements pursuant
  to which  any  member of the Hornbeck Group has guaranteed
  an obligation of  any  member of the North Sea Group where
  assets other than vessels  are collateral other than those
  set forth on Schedule 4.11(a).   A  member of the Hornbeck
  Consolidated Group and, to the Knowledge  of  Hornbeck,  a
  member  of  the  North  Sea  Group,  owns,  or  has  valid
  leasehold  interests  in, all properties and assets, other
  than vessels, used in the conduct of its business.

            (b)   With respect  to  each  lease  of any real
  property, or a material amount of other personal  property
  (other  than  vessels)  to  which a member of the Hornbeck
  Consolidated Group is a party,  (i)  such  member  of  the
  Hornbeck Consolidated Group has a valid leasehold interest
  in  such  real  property  or  personal property; (ii) such
  lease is in full force and effect  in  accordance with its
  terms;  (iii)  all rents and other monetary  amounts  that
  have become due  and  payable thereunder have been paid in
  full; (iv) no waiver, indulgence  or  postponement  of the
  obligations thereunder has been granted by the other party
  thereto; (v) there exists no material default (or an event
  that,   with  notice  or  lapse  of  time  or  both  would
  constitute a material default) under such lease; (vi) such
  member of the Hornbeck Consolidated Group has not violated
  any of the terms or conditions under any such lease and to
  the Knowledge of Hornbeck there has been no, (A) condition
  or covenant to be observed or performed by any other party
  under any  such lease that has not been fully observed and
  performed  and  (B)  in  the  case  of  each  prime  lease
  concerning demised premises subleased to any member of the
  Hornbeck Consolidated  Group,  condition or covenant to be
  observed or performed by each party  thereto  that has not
  been fully observed and performed and there does not exist
  any  event  of default or event, occurrence, condition  or
  act that, with  the giving of notice, the lapse of time or
  the happening of  any  further  event  or condition, would
  become a default under any such prime lease; and (vii) the
  transactions   described  in  this  Agreement   will   not
  constitute a default  under  or  cause  for termination or
  modification of such lease.

            (c)   The  rent  charged  to any member  of  the
  Hornbeck Group under any lease, other than with respect to
  vessels, between any member of the Hornbeck  Group and any
  of  its  Affiliates  (other  than  another  member of  the
  Hornbeck  Group)  is at or below the market rate  and  any
  such lease  contains  such other terms and conditions that
  are no less favorable to Hornbeck than would be obtainable
  in an arms-length transaction  with  an  independent third
  party lessor.

            (d)   Schedule 4.11(d) contains  a  list  of all
  real property owned by members of the Hornbeck Group and a
  list of all leases, other than with respect to vessels, to
  which the members of the Hornbeck Group are parties, which
  list includes a reasonable description of the location and
  approximate square footage of each property, whether owned
  or leased, and the term of each such lease, including  all
  renewal  options.   Complete  and  correct  copies of each
  lease have been delivered to Tidewater.

       Section 4.12  Condition  of  Hornbeck's  Assets Other
  than Vessels.  All of the tangible assets  of the Hornbeck
  Consolidated Group (other than vessels) are  currently  in
  good   and   usable  condition,  ordinary  wear  and  tear
  excepted, and  are  being  used  in  the  business  of the
  Hornbeck Consolidated Group.  There are no defects in such
  assets   or   other  conditions  that  have  or  would  be
  reasonably likely  to  have,  a Material Adverse Effect on
  Hornbeck.   Such  assets and the  other  properties  being
  leased by a member  of  the Hornbeck Group pursuant to the
  leases described on Schedule  4.11(d),  together  with the
  vessels  listed  on  Schedule 4.13, constitute all of  the
  operating assets being  utilized  by the Hornbeck Group in
  the conduct of its business and such assets are sufficient
  in quantity and otherwise adequate  for  the operations of
  the Hornbeck Group as currently conducted.

       Section 4.13  Vessels.   (a) Schedule 4.13(a)  hereto
  sets forth a list of all vessels owned,  leased, chartered

  hereof  and the name of the nation under which  each  such
  vessel is  documented  and flagged, and indicates any such
  vessels that are laid up  or  being  held  for sale on the
  date  hereof  (such  vessels (other than any such  vessels
  that are managed on the  date  hereof)  being  referred to
  herein as "Hornbeck Vessels").  With respect to  the owned
  Hornbeck Vessels, a member of the Hornbeck Group has  good
  title  to  each  such  vessel free and clear of all Liens,
  except for (i) Liens that  collateralize indebtedness that
  is properly reflected in the Hornbeck Latest Balance Sheet
  or the North Sea Group Latest  Balance  Sheet;  (ii) Liens
  for  Taxes  accrued  but  not yet payable; (iii) Permitted
  Liens provided that the obligations collateralized by such
  Permitted Liens are not delinquent  or are being contested
  in  good  faith  and  in  no event shall the  obligations,
  individually or in the aggregate,  collateralized  by such
  contested   Permitted   Liens   exceed   $150,000  in  the
  aggregate.  Schedule 4.13(a) contains a list  of all Liens
  (other  than  Permitted  Liens) on vessels collateralizing
  indebtedness on the Hornbeck  Latest  Balance Sheet or the
  North Sea Group Latest Balance Sheet and  any  guaranty or
  other  credit  support  arrangement pursuant to which  any
  member of the Hornbeck Group  has guaranteed an obligation
  of any other member of the Hornbeck  Group  where  vessels
  are the collateral.

       (b)  With  respect  to  each Hornbeck Vessel that  is
  operated by a member of the Hornbeck  Group under lease or
  charter, (i) such member of the Hornbeck Group has a valid
  right  to  charter or a valid leasehold interest  in  such
  vessel; (ii)  such  charter  agreement or lease is in full
  force and effect in accordance  with  its terms; (iii) all
  rents,  charter payments and other monetary  amounts  that
  have become  due  and payable thereunder have been paid in
  full; (iv) no waiver,  indulgence  or  postponement of the
  obligations thereunder has been granted by the other party
  thereto; (v) there exists no material default (or an event
  that,  with  notice  or  lapse  of  time  or  both   would
  constitute   a   material   default)  under  such  charter
  agreement or lease; (vi) such member of the Hornbeck Group
  has not violated any of the terms  or conditions under any
  such charter agreement or lease and  to  the  Knowledge of
  Hornbeck there is no condition or covenants to be observed
  or  performed  by  any  other  party  under  such  charter
  agreement  or  lease  that has not been fully observed  or
  performed; and (viii) the  transactions  described in this
  Agreement will not constitute a default under or cause for
  termination or modification of such charter  agreement  or
  lease.

       (c)  Schedule  4.13(c)  contains a list of all leases
  or charters providing for the  use  by  a  member  of  the
  Hornbeck  Group  of a Hornbeck Vessel other than leases or
  charters between members  of  the  North  Sea Group, which
  list contains a description of the terms of  such lease or
  charter.   Complete  and correct copies of each  lease  or
  charter have been delivered to Tidewater.

       (d)  With respect  to each Hornbeck Vessel:  (i) such
  Hornbeck Vessel is lawfully  documented  under the flag of
  the  nation  listed  on  Schedule  4.13 for such  Hornbeck
  Vessel,  (ii)  such  Hornbeck  Vessel  is  afloat  and  in
  satisfactory operating condition for charter  hire,  (iii)
  such  Hornbeck  Vessel  holds in full force and effect all
  certificates, licenses, permits  and  rights  required for
  operation  in  the  manner  vessels of its kind are  being
  operated in the geographical  area  in which such Hornbeck
  Vessel is presently being operated and  (iv)  no event has
  occurred  and no condition exists that would endanger  the
  maintenance of the classification of such Hornbeck Vessel.

       Section 4.14  Voting  Requirements.  The  affirmative
  vote  of  the  holders  of  not less than 66-2/3%  of  the
  outstanding shares of Hornbeck  Common  Stock  entitled to
  vote on the Merger is the only vote of the holders  of any
  class  or series of Hornbeck's capital stock necessary  to
  approve  this  Agreement  and  the  transactions described
  herein.

       Section  4.15  State   Takeover  Statutes;   Hornbeck
  Stockholder Rights Plan.  (a)  The Board  of  Directors of
  Hornbeck has approved the Merger, this Agreement  and  the
  transactions   described   in   this  Agreement,  and  the
  provisions of Section 203 of the  DGCL are inapplicable to
  the Merger, this Agreement and the  transactions described
  in this Agreement; provided, however,  that  the foregoing
  shall not be construed to mean that the Board of Directors
  of  Hornbeck  has  approved  any  stockholder  of Hornbeck
  becoming  an  "Interested  Stockholder"  for  purposes  of
  Section 203 of the DGCL.  No other state takeover  statute
  or  similar  statute or regulation applies or purports  to
  apply to Hornbeck  in  connection  with  the  Merger, this
  Agreement  or  any of the transactions described  in  this
  Agreement.

       (b)  The Board of Directors of Hornbeck has taken all
  action necessary  to render the provisions of the Hornbeck
  Stockholder Rights  Plan  inapplicable  to  Tidewater, the
  Merger,  this Agreement and the transactions described  in
  this Agreement.

       Section 4.16  Accounting  Matters.  No  member of the
  Hornbeck  Group, nor to the Knowledge of Hornbeck  any  of
  its Affiliates,  has  taken  or  agreed to take any action
  that (without giving effect to any  action taken or agreed
  to be taken by Tidewater or any of its  Affiliates)  would
  prevent   Tidewater   from  accounting  for  the  business
  combination to be effected  by the Merger as a pooling-of-
  interests.  Within three business days of the execution of
  this Agreement, Hornbeck will  have  received letters from
  its  independent  public  accountants  and  the  Tidewater
  independent public accountants to the effects  that if the
  Merger  were  to  be  consummated  on  the  date  of  this
  Agreement,   it  would  qualify  for  pooling-of-interests
  treatment  under   the   generally   accepted   accounting
  principles of the United States.

       Section  4.17  Suppliers   and  Customers.    To  the
  Knowledge of Hornbeck, (a) no supplier providing products,
  materials or services to any member of the Hornbeck  Group
  intends  to  cease  selling  such  products,  materials or
  services to any member of the Hornbeck Group or  to  limit
  or  reduce  such sales to any member of the Hornbeck Group
  or materially  alter  the  terms or conditions of any such
  sales and (b) no customer of  any  member  of the Hornbeck
  Group intends to terminate, limit or reduce  its  or their
  business relations with any member of the Hornbeck Group.

       Section 4.18  Employee Matters.  (a) Schedule 4.18(a)
  sets forth the  name,  title,  current annual compensation
  rate  (including  bonus  and  commissions),  current  base
  salary rate, accrued bonus, accrued  sick  leave,  accrued
  severance  pay  and  accrued  vacation  benefits  of  each
  officer of each member of the Hornbeck Consolidated Group,
  and   a  list  of  all  employment,  consulting,  employee
  confidentiality  or similar agreements to which any member
  of the Hornbeck Consolidated  Group is a party.  Copies of
  organizational charts, any employee  handbook(s),  and any
  reports  and/or plans prepared or adopted pursuant to  the
  Equal Employment Opportunity Act of 1972, as amended, have
  been provided to Tidewater.

            (b)   Each of the following is true with respect
  to the Hornbeck  Consolidated  Group and, to the Knowledge
  of Hornbeck, the North Sea Group:

                  (i) each such member is in compliance with
  all applicable laws respecting employment  and  employment
  practices,  terms and conditions of employment, wages  and
  hours and occupational  safety  and  health,  and  is  not
  engaged in any unfair labor practice within the meaning of
  Section 8  of  the National Labor Relations Act, and there
  is  no  proceeding   pending   or   threatened,   or,  any
  investigation pending or threatened against it relating to
  any thereof, and to the Knowledge of Hornbeck there  is no
  basis for any such proceeding or investigation;

                  (ii)none  of  the  employees  of  any such
  member is a member of, or represented by, any labor  union
  and  there  are  no  efforts being made to unionize any of

                  (iii)there  are  no  charges  of,  formal,
  informal   or   internal  complaints  of,  or  proceedings
  involving, discrimination or harassment (including but not
  limited to discrimination  or  harassment  based upon sex,
  age,   marital  status,  race,  religion,  color,   creed,
  national  origin,  sexual  preference, handicap or veteran
  status)  pending  or  threatened,   nor   is   there   any
  investigation  pending  or  threatened, including, but not
  limited  to, investigations before  the  Equal  Employment
  Opportunity  Commission  or  any  federal,  state or local
  agency or court, with respect to any such member.

       Section 4.19  Employee Benefit Plans. With respect to
  any member of the Hornbeck Consolidated Group:

            (a)   Schedule 4.19(a) lists each Employee  Plan
  that  each  member  of  the  Hornbeck  Consolidated  Group
  maintains,   administers,   contributes  to,  or  has  any
  contingent liability with respect  thereto.   Hornbeck has
  provided  a  true and complete copy of each such  Employee
  Plan,  current   summary   plan   description,   (and,  if
  applicable,  related  trust  documents) and all amendments
  thereto and written interpretations  thereof together with
  (i) the  three  most  recent  annual reports  prepared  in
  connection  with  each  such  Employee   Plan  (Form  5500
  including,  if  applicable, Schedule B thereto);  (ii) the
  most recent actuarial  report,  if  any, and trust reports
  prepared in connection with each Employee  Plan; (iii) all
  material  communications  received  from  or sent  to  the
  Internal  Revenue  Service  ("IRS")  or the Department  of
  Labor  within  the  last  two years (including  a  written
  description of any material oral communications); (iv) the
  most recent IRS determination  letter with respect to each
  Employee  Plan  and  the  most recent  application  for  a
  determination letter; (v) all insurance contracts or other
  funding arrangements; and (vi)  an  actuarial study of any
  post-employment life or medical benefits provided, if any.

            (b)   Schedule 4.19(b) identifies  each  Benefit
  Arrangement  that each member of the Hornbeck Consolidated
  Group maintains,  administers,  contributes to, or has any
  contingent liability with respect  thereto.   Hornbeck has
  furnished  to  Tidewater  copies  or descriptions of  each
  Benefit Arrangement and any of the  information  set forth
  in   Section   4.19(a)  applicable  to  any  such  Benefit
  Arrangement.  Each Benefit Arrangement has been maintained
  and administered  in substantial compliance with its terms
  and   with   the   requirements    (including    reporting
  requirements) prescribed by any and all statutes,  orders,
  rules and regulations which are applicable to such Benefit
  Arrangement.

            (c)   Benefits   under   any  Employee  Plan  or
  Benefit Arrangement are as represented  in  said documents
  and  have not been increased or modified (whether  written
  or not written) subsequent to the dates of such documents.
  No  member   of   the   Hornbeck  Consolidated  Group  has
  communicated  to  any  employee  or  former  employee  any
  intention or commitment  to  modify  any  Employee Plan or
  Benefit Arrangement or to establish or implement any other
  employee or retiree benefit or compensation arrangement.

            (d)   No  Employee  Plan  is (i) a Multiemployer
  Plan,  (ii) a  Title  IV  Plan or (iii) is  maintained  in
  connection with any trust described  in  Section 501(c)(9)
  of the Code.  No member of the Hornbeck Consolidated Group
  has ever maintained or become obligated to  contribute  to
  any  employee benefit plan (i) that is subject to Title IV
  of ERISA,  (ii) to  which Section 412 of the Code applies,
  or (iii) that is a Multiemployer  Plan.   No member of the
  Hornbeck Consolidated Group has within the last five years
  engaged  in,  or is a successor corporation to  an  entity
  that has engaged  in,  a  transaction described in Section
  4069 of ERISA.

            (e)   Each Employee Plan which is intended to be
  qualified under Section 401(a) of the Code is so qualified
  and  has  been so qualified during  the  period  from  its
  adoption to  date,  and  no  event has occurred since such
  adoption that would adversely  affect  such  qualification
  and  each  trust  created  in  connection  with each  such
  Employee  Plan forming a part thereof is exempt  from  tax
  pursuant to  Section  501(a)  of  the  Code.   A favorable
  determination letter has been issued by the IRS  as to the
  qualification  of  each such Employee Plan under the  Code
  and to the effect that  each  such  trust  is  exempt from
  taxation under Section 501(a) of the Code.  Each  Employee
  Plan  has  been  maintained and administered in compliance
  with  its  terms  and  with  the  requirements  (including
  reporting  requirements)   prescribed   by   any  and  all
  applicable   statutes,   orders,  rules  and  regulations,
  including but not limited to ERISA and the Code.

            (f)   Full payment  has been made of all amounts
  which any member of the Hornbeck  Consolidated Group is or
  has  been  required  to have paid as contributions  to  or
  benefits  due  under  any   Employee   Plan   or   Benefit
  Arrangement under applicable law or under the terms of any
  such plan or any arrangement.

            (g)   No  member  of  the  Hornbeck Consolidated
  Group, or any of their respective directors,  officers  or
  employees  has  engaged in any transaction with respect to
  an Employee Plan  that  could  subject  Hornbeck to a tax,
  penalty  or  liability  for  a prohibited transaction,  as
  defined in Section 406 of ERISA  or  Section  4975  of the
  Code.   None  of  the  assets  of  any  Employee  Plan are
  invested in employer securities or employer real property.

            (h)   To the Knowledge of Hornbeck, there are no
  facts  or  circumstances  that  might  give  rise  to  any
  liability under Title I of ERISA.

            (i)   No  member  of  the  Hornbeck Consolidated
  Group has any current or projected liability in respect of
  post-retirement  or post-employment welfare  benefits  for
  retired, current or  former  employees, except as required
  to avoid excise tax under Section 4980B of the Code.

            (j)   Except as disclosed  on  Schedule 4.19(j),
  there  is  no  litigation,  administrative or  arbitration
  proceeding  or other dispute pending  or  threatened  that
  involves any  Employee  Plan  or Benefit Arrangement which
  could reasonably be expected to  result  in a liability to
  the Hornbeck Consolidated Group or Tidewater.

            (k)   No  employee  or  former employee  of  any
  member  of  the Hornbeck Consolidated  Group  will  become
  entitled to any bonus, retirement, severance, job security
  or  similar  benefit   or   enhanced   benefit  (including
  acceleration  of  an  award,  vesting  or exercise  of  an
  incentive award) or any fee or payment of  any kind solely
  as  a  result  of  any  of  the  transactions contemplated
  hereby,  except as disclosed on Schedule  4.19(k)  and  no
  such disclosed  payment  constitutes  a  parachute payment
  described in Section 280G of the Code, except as disclosed
  on Schedule 4.19(k).

            (l)   To  the Knowledge of Hornbeck,  all  group
  health plans (as defined  in  Code  Section 5000(b)(1)) of
  any member of the Hornbeck Consolidated  Group have at all
  times fully complied with all applicable notification  and
  continuation  coverage requirements of Section 4980B(f) of
  the Code and Section  601  of  ERISA,  and the regulations
  promulgated   thereunder.    Further,  no  Employee   Plan
  provides health, medical, death  or  survivor  benefits to
  any  stockholders  or  directors  who  are  not employees,
  former employees or beneficiaries thereof, except  to  the
  extent otherwise required by the continuation requirements
  of Section 4980B(f) of the Code and Section 601 of ERISA.

            (m)   No employee or former employee, officer or
  director  of any member of the Hornbeck Consolidated Group
  is or will  become  entitled  to  receive  any award under
  Hornbeck's discretionary or other bonus plans  except  for
  (i)  cash  payments  pursuant  to  Section 6.4(j) of up to
  $350,000 in 1995 Incentive Cash Payments  (as  defined  in
  Section  6.4(j)),  (ii)  the  issuance pursuant to Section
  6.4(j)  of  an aggregate of 19,310  shares  of  restricted
  Hornbeck Common  Stock  for  1995 performance and (iii) if
  the Closing Date has not occurred  by April 30, 1996, cash
  payments to officers and employees as  incentive  payments
  for  1996 performance for the period from January 1,  1996
  through  the Closing Date, such amounts to be prorated and
  based on the  total  1995  Incentive  Cash Payments and to
  otherwise be consistent with past practice.

  4.20(a)(ii), each member of the Hornbeck  Group  has  paid
  all  Taxes required to be paid by it (whether or not shown
  on a Return)  or  for  which it could be liable, (provided
  that  it  shall  not  be  considered   a  breach  of  this
  representation   if  it  is  ultimately  determined   that
  additional tax payments  are  due  but  such assessment is
  based  on an adjustment to a return or position,  if  such
  member has  a reasonable basis for the position taken with
  respect to such  Taxes),  whether to taxing authorities or
  to  other  persons  under  tax  allocation  agreements  or
  otherwise, and the charges,  accruals,  and  reserves  for
  Taxes  due,  or  accrued  but not yet due, relating to its

  required  by  law to withhold or collect  have  been  duly
  withheld or collected,  and  have been timely paid over to
  the appropriate governmental authorities to the extent due
  and payable (provided that it  shall  not  be considered a
  breach   of   this  representation  if  it  is  ultimately
  determined that  additional  tax payments are due but such
  assessment  is  based  on an adjustment  to  a  return  or
  position, if such member  has  a  reasonable basis for the

  jurisdiction  in  which  any  member of the Hornbeck Group
  has, in the last three years, filed a Return.

                  (viii)all Tax Deficiencies which have been
  claimed, proposed or asserted against  any  member  of the
  Hornbeck  Group  have  been fully paid or finally settled,
  and no issue has been raised  in any examination which, by

  income law) apply to any disposition of any asset owned by
  it.

                  (xiii)except  as  set  forth  on  Schedule
  4.20(a)(xiii),  none  of  the assets of any member of  the
  Hornbeck Group is property  that  such company is required
  to treat as being owned by any other  person  pursuant  to
  the  so-called  "safe  harbor  lease" provisions of former
  Section 168(f)(8) of the Code.

                  (xiv)none of the  assets  of any member of

  is (or has ever been) a party to any tax sharing agreement
  nor has any such member assumed the tax liability  of  any
  other person under contract.

            (b)   Hornbeck  has received an opinion of Price
  Waterhouse  LLP to the effect  that  the  Merger  will  be
  treated   for   federal   income   tax   purposes   as   a
  reorganization within the meaning of Section 368(a) of the
  Code, and that Hornbeck and Tidewater will each be a party
  to  such reorganization  within  the  meaning  of  Section
  368(b) of the Code.

       Section 4.21  Litigation.   Except  as  disclosed  on
  Schedule 4.21, there  are  no actions, suits, proceedings,
  arbitrations  or  investigations   pending   or,   to  the
  Knowledge  of  Hornbeck, threatened before any court,  any
  governmental agency  or instrumentality or any arbitration
  panel, against or affecting  any  member  of  the Hornbeck
  Consolidated  Group or, to the Knowledge of Hornbeck,  any
  member of the North  Sea  Group,  or any of the directors,
  officers, or employees of the foregoing.  To the Knowledge
  of Hornbeck, no facts or circumstances exist that would be
  likely  to result in the filing of any  such  action  that
  would have  a Material Adverse Effect on Hornbeck.  Except
  as disclosed  on  Schedule 4.21, no member of the Hornbeck
  Group is subject to  any currently pending judgment, order
  or decree entered in any lawsuit or proceeding.

       Section 4.22 Insurance. Schedule 4.22 contains a list
  of the insurance policies that each member of the Hornbeck
  Consolidated Group currently maintains with respect to its
  business, vessels, properties  and  employees as well as a
  list of all hull and machinery, protection  and indemnity,
  pollution,   and   comprehensive   contractual   liability
  insurance policies that each member of the North Sea Group
  maintains  with  respect  to  its  vessels, as of the date
  hereof, each of which is in full force  and  effect  and a
  complete  and  correct  copy of each has been delivered to
  Tidewater.   All insurance  premiums  currently  due  with
  respect to such  policies  have been paid and no member of
  the Hornbeck Group is otherwise in default with respect to
  any such policy, nor has any  member of the Hornbeck Group
  failed to give any notice or to  present  any  claim under
  any such policy in a due and timely manner.  There  are no
  outstanding unpaid claims under any such policy other than
  any   pending   claims  under  any  of  Hornbeck's  marine
  insurance policies,  the  amount of which claims have been
  recorded  as  a receivable and  all  of  which  are  fully
  collectible.  No member of the Hornbeck Group has received
  notice of cancellation  or non-renewal of any such policy.
  In the opinion of management  of  Hornbeck,  such policies
  are sufficient for compliance with all requirements of law
  and  all  agreements  to which any member of the  Hornbeck
  Group is a party.

  as otherwise  disclosed  to  those  executive  officers of
  Tidewater  listed  on Schedule 4.23(b), no member  of  the

  received any notice of any violation of, or claim alleging
  liability  under, any  Environmental  Laws,  and,  to  the
  Knowledge of  Hornbeck,  no  facts  or circumstances exist
  that  would  be likely to result in a claim,  citation  or
  allegation against  any member of the Hornbeck Group for a
  violation   of,   or   alleging   liability   under,   any
  Environmental Laws that  would  have  a  Material  Adverse
  Effect on Hornbeck.

            (c)   There are no underground tanks of any type
  (including  tanks  storing  gasoline, diesel fuel, oil  or
  other petroleum products) or  disposal sites for hazardous
  substances, hazardous wastes or  any  other waste, located

  used by any  member  of  the  Hornbeck  Group  and  to the
  Knowledge  of  Hornbeck  there were no such disposal sites
  located  on  or under the real  estate  previously  owned,
  leased or used  by any member of the Hornbeck Group on the
  date of the sale  thereof  by  any  member of the Hornbeck
  Group or during the period of lease for  use by any member

  The disposal by each member of  the  Hornbeck Group of its
  hazardous  substances  and wastes has been  in  compliance
  with all Environmental Laws.

       Tidewater  shall not  be  entitled  to  assert  as  a
  failure by Hornbeck  to satisfy the condition set forth in
  Section 7.2(a) a breach  of  the representations set forth

  the disclosure in the first paragraph of Schedule 4.23(b).

  necessary  for  a  fair statement of the results  for  the
  interim  periods presented  therein.   No  member  of  the

  absolute or contingent, accrued,  fixed,  known,  unknown,
  matured  or  unmatured),  except  (i) as and to the extent
  reflected on the Tidewater Latest Balance  Sheet,  or (ii)

  Balance Sheet, there has been no change that has had or is
  likely to have a Material Adverse Effect on Tidewater.

            (e)   Except  as set forth in  Schedule  5.7(e),
  the  statements  of earnings  included  in  the  Tidewater
  Financial Statements  do not contain any income or revenue
  realized  from services  that  the  Surviving  Corporation
  would be prohibited  or restricted from offering after the
  Effective Time pursuant  to  any  covenant or provision in
  any material contract to which any member of the Tidewater
  Affiliated Group is a party.

  ARTICLE 6.  PRE-CLOSING COVENANTS

       Section 6.1 Hart-Scott-Rodino; Cooperation  and  Best
  Efforts.  (a)   Hornbeck  and Tidewater shall cooperate in
  good faith and take all actions  reasonably  necessary  or
  appropriate  to  file,  and  expeditiously  and diligently
  prosecute  to  a  favorable  conclusion,  the HSR  Reports
  required  to  be  filed  by  each  of  them  in connection
  herewith with the Federal Trade Commission (the "FTC") and
  the Department of Justice (the "DOJ") pursuant  to the HSR
  Act;  provided  that  Tidewater  shall not be required  to
  accept any conditions that may be  imposed  by  the FTC or
  the DOJ in connection with such filings that would require
  the  divestiture  of  any Tidewater or Hornbeck assets  or
  otherwise have a Material Adverse Effect on such party.

            (b)   Hornbeck and Tidewater agree that from the
  date of this Agreement through the Effective Time, neither
  party shall enter into  any transaction with a third party
  or recapitalization that would have the effect of impeding
  the ability to obtain HSR Act clearance; provided that (i)
  the exercise by Tidewater  of  options  to  acquire  seven
  vessels  currently  under  lease  and (ii) the exercise by
  Hornbeck of either or both of the Ravensworth  Options  in
  accordance  with  Section  6.11  shall not be considered a
  breach of this covenant.

            (c)   Each party shall cooperate  with the other
  and  use  its  reasonable best efforts to (i) receive  all
  necessary and appropriate consents of third parties to the

  complying with all the requirements of the  Securities Act
  applicable  thereto, for the purpose, among other  things,
  of registering  the  Tidewater  Common Stock which will be
  issued to the holders of Hornbeck Common Stock pursuant to
  the Merger.  Tidewater shall use its best efforts to cause
  the Registration Statement to become  effective as soon as
  practicable, to qualify the Tidewater Common  Stock  under
  the  securities or blue sky laws of such jurisdictions  as
  may be required and to keep the Registration Statement and
  such qualifications  current  and in effect for so long as
  necessary  to  consummate  the  transactions  contemplated
  hereby.  In addition, Tidewater shall use its best efforts
  to cause the Tidewater Common Stock  to be issued pursuant
  to the Merger to be listed on the New  York Stock Exchange
  and Pacific Stock Exchange and be fully  tradeable  except
  to  the  extent  any  shares  of  Tidewater  Common  Stock
  received  by  stockholders  of Hornbeck are subject to the
  provisions of Rule 145 of the  SEC or are restricted under
  applicable rules related to tax-free  reorganizations  and
  pooling-of-interest accounting rules.

            (b)   Each  of the parties will cooperate in the
  preparation of the Registration  Statement  and  the Proxy

  request  for  the  purpose  of  including  such  data  and
  information  in  the  Registration   Statement  and  Proxy
  Statement.

            (c)   Hornbeck  shall,  as soon  as  practicable
  following  effectiveness  of  the Registration  Statement,

  special   meeting   of  its  stockholders  (the   "Special
  Meeting") for the purpose  of  approving  this  Agreement.
  Hornbeck  will,  through its Board of Directors, recommend
  to its stockholders  approval  of  this  Agreement and the
  transactions described herein, subject to  the  terms  set
  forth in Section 6.5 hereof.

  provided  that  the  foregoing  language  of  this Section

            (d)   except  as  disclosed on Schedule  6.4(d),

  bonds in the ordinary course of  business  consistent with
  past  practices,  but including any borrowings  under  the
  existing Hornbeck credit  facility  with  First Interstate
  Bank of Texas N.A. (provided that, to the extent  Hornbeck

  portion   of  such  facility);  or  guarantee   any   such

  to  January  2,  1996,  and  provided further that, if the
  Closing Date has not occurred  by  April  30,  1996,  cash
  payments   may  be  made  to  officers  and  employees  as
  incentive payments  for  1996  performance  for the period
  from  January  1,  1996  through  the  Closing Date,  such
  amounts  to  be  prorated  and  based  on the  total  1995
  Incentive  Cash  Payments and to otherwise  be  consistent
  with past practice; or

            (k)   authorize any of, or agree or commit to do
  any of, the foregoing actions.

  In addition, Hornbeck  shall  consult  with Tidewater with
  respect to any action of the type described above proposed
  to be taken by a member of the North Sea Group.

       Section 6.5  No Solicitations.  (a) No  member of the
  Hornbeck  Group shall directly or indirectly, through  any
  officer, director,  employee,  representative  or agent of
  any member of the Hornbeck Group, solicit or encourage the
  initiation  or  submission of any inquiries, proposals  or
  offers regarding  any  acquisition, merger, take-over bid,
  sale of all or substantially  all  of  the  assets  of, or
  sales  of shares of capital stock of Hornbeck, whether  or
  not  in writing  and  whether  or  not  delivered  to  the
  stockholders  of  Hornbeck  generally  (including  without
  limitation   by   way  of  a  tender  offer),  or  similar
  transactions involving  Hornbeck  (any  of  the  foregoing
  inquiries  or  proposals  being  referred to herein as  an
  "Acquisition Proposal"); provided,  however,  that nothing
  contained  in  this  Agreement shall prevent the Board  of
  Directors of Hornbeck  from  referring  any third party to
  this Section 6.5.  Nothing contained in this  Section  6.5
  or any other provision of this Agreement shall prevent the
  Board   of  Directors  of  Hornbeck  from  considering  or
  negotiating  an  unsolicited bona fide written Acquisition
  Proposal.  If the  Board  of  Directors of Hornbeck, after
  duly considering advice, written  or otherwise, of outside
  counsel and financial advisors to Hornbeck,  determines in
  good faith that it would be consistent with its  fiduciary
  responsibilities   to   approve   or   recommend  (and  in
  connection therewith withdraw or modify  its  approval  or
  recommendation  of  this  Agreement,  and the transactions
  contemplated  hereby or thereby) a Superior  Proposal  (as
  defined below), then, notwithstanding any such approval or
  recommendation  (x)  Hornbeck  shall  not  enter  into any
  agreement  with  respect to the Superior Proposal and  (y)
  any other obligation  of  Hornbeck  under  this  Agreement
  shall not be affected, unless this Agreement is terminated
  pursuant   to   Section   9.1(f)   hereof   prior   to  or
  simultaneously  with  the  grant  of  such approval or the
  making of such recommendation and Hornbeck,  within  three
  Business  Days  following  such termination resulting from
  such Superior Proposal, pays Tidewater the Termination Fee
  (as defined in Section 9.1(f)).   As  used herein the term
  "Superior Proposal" means a bona fide proposal  made  by a
  third  party  to  acquire Hornbeck pursuant to a tender or
  exchange offer, a merger,  a  sale of all or substantially
  all of its assets or otherwise that the Board of Directors
  determines in its good faith judgment to be more favorable
  to   Hornbeck's   stockholders   than   the   transactions
  contemplated  by  this  Agreement (after  considering  the
  advice, written or otherwise,  of  Hornbeck's professional
  advisors).   In  making  a  determination   of  whether  a
  Superior Proposal is more favorable, the Hornbeck Board of
  Directors shall consider not only the price offered by the
  third  party  as  compared to the total consideration  set
  forth in this Agreement, but shall also compare the market
  liquidity of the Tidewater  Common  Stock to the liquidity
  of the consideration offered by the third  party,  compare
  the tax consequences of the Merger to the tax consequences
  of  the transaction proposed by the third party, determine
  whether  the  transaction  proposed by the third party has
  any financing or other conditions  or  contingencies,  and
  make  any  other  meaningful  comparison  of  the relative
  benefits  offered  to  the  Hornbeck  stockholders by  the
  Merger  as  compared  to the transaction proposed  by  the
  third party.

            (b)   Hornbeck    shall    immediately    notify
  Tidewater after receipt of any Acquisition Proposal or any
  request  for  nonpublic information relating to any member
  of the Hornbeck  Group  in  connection with an Acquisition
  Proposal or for access to the properties, books or records
  of any member of the Hornbeck Group that informs the Board
  of Directors of any member of  the  Hornbeck Group that it
  is  considering  making,  or  has  made,  an   Acquisition
  Proposal.  To the extent not prohibited by confidentiality
  provisions  imposed by the offering party, such notice  to
  Tidewater shall  be  made  orally and in writing and shall
  indicate in reasonable detail  the identity of the offeror
  and the terms and conditions of  such proposal, inquiry or
  contact.

            (c)   If  the  Board  of Directors  of  Hornbeck
  receives a request for material nonpublic information by a
  Person  who  makes,  or  who  states in  writing  that  it
  intends, subject to satisfactory  review of such nonpublic
  information,  to  make, a bona fide Acquisition  Proposal,
  Hornbeck   may,   subject    to   the   execution   of   a
  confidentiality agreement substantially  similar  to  that
  then  in  effect  between  Hornbeck and Tidewater, provide
  such Person with access to information regarding Hornbeck.

            (d)   Nothing  contained  in  this  Section  6.5
  shall prevent Hornbeck from  complying  with Rule 14e-2(a)
  or  Rule  14d-9  promulgated  under the Exchange  Act,  if
  applicable, with regard to an Acquisition Proposal made in
  the form of a tender offer by a third party.

       Section 6.6  Press Releases.  Hornbeck and  Tidewater
  will  consult  with each other before issuing, and provide
  each other the opportunity to review and comment upon, any
  press releases or  other public statements with respect to
  any transactions described  in  this  Agreement, including
  the Merger, and shall not issue any such press releases or
  make any such public statement prior to such consultation,
  except as may be required by applicable law, court process
  or by obligations pursuant to a listing agreement with the
  Nasdaq National Market or the New York Stock Exchange.

       Section 6.7 Access to Information and Confidentiality.
  (a)   Prior  to  the  Closing Date, each of  Hornbeck  and
  Tidewater shall afford  to  the  other  party  and  to the
  officers,   employees,   accountants,  counsel,  financial
  advisors and other representatives  of  such  other party,
  reasonable  access during normal business hours  to  their
  respective premises, books and records and will furnish to
  the other party  (i)  a  copy  of  each  report, schedule,
  registration  statement and other documents  filed  by  it
  during such period pursuant to the requirements of federal
  or state securities  laws, and (ii) such other information
  with respect to its business  and properties as such other
  party reasonably requests.

            (b)   Each of Hornbeck  and  Tidewater will, and
  will cause its officers, directors, employees,  agents and
  representatives   to,   (i)  hold  in  confidence,  unless
  compelled  to  disclose  by   judicial  or  administrative
  process,  or,  in the opinion of  its  counsel,  by  other
  requirements of  law, all nonpublic information concerning
  the  other  party  furnished   in   connection   with  the
  transactions  contemplated  by  this Agreement until  such
  time  as  such  information  becomes   publicly  available
  (otherwise than through the wrongful act  of such person),
  (ii) not release or disclose such information to any other
  person,  except in connection with this Agreement  to  its
  auditors, attorneys, financial advisors, other consultants
  and advisors,  and  (iii) not use such information for any
  competitive or other  purpose  other  than with respect to
  its  consideration  and  evaluation  of  the  transactions
  contemplated   by   this  Agreement.   In  the  event   of
  termination of this Agreement for any reason, Hornbeck and
  Tidewater will promptly  return  or  destroy all documents
  containing  nonpublic  information  so obtained  from  the
  other party and any copies made of such  documents and any
  summaries, analyses or compilations made therefrom.

       Section 6.8  Consultation and Reporting.   During the
  period from the  date  of  this  Agreement  to the Closing
  Date, each of Hornbeck and Tidewater will, subject  to any
  applicable  legal or contractual restrictions confer on  a
  regular  and frequent  basis  with  the  other  to  report
  material operational  matters and to report on the general
  status  of  ongoing  operations.   Each  of  Hornbeck  and
  Tidewater  will  notify   the   other  of  any  unexpected
  emergency  or other change in the  normal  course  of  its
  business or  in the operation of its properties and of any
  governmental  complaints,   investigations,   adjudicatory
  proceedings,  or  hearings  (or  communications indicating
  that the same may be contemplated) and will keep the other
  fully   informed   of   such   events   and   permit   its
  representatives prompt access to all materials prepared by
  or  on  behalf  of  such  party  or  served  on  them,  in
  connection therewith.

       Section 6.9  Update Schedules. Each party hereto will
  promptly  disclose  to the other any information contained
  in its representations  and  warranties and on the related
  schedules that, because of an  event  occurring  after the
  date hereof, is incomplete or no longer correct; provided,
  however,  that none of such disclosures will be deemed  to
  modify,  amend   or  supplement  the  representations  and
  warranties of such  party, unless the other party consents
  to such modification, amendment or supplement in writing.

       Section 6.10  Hornbeck Stock  Options.   The  parties
  acknowledge and  agree  that,  pursuant to Article XIII of
  the Hornbeck 1989 Employee Incentive Plan and Article XIII
  of the Hornbeck 1993 Employee Incentive  Plan,  any of the
  Hornbeck  Disclosed  Employee  Stock Options issued  under
  such plans that remain unexercised  as of the Closing Date
  shall, in accordance with their terms,  become  options to
  acquire  such  number of shares of Tidewater Common  Stock
  that the holder  of  such  unexercised  Hornbeck Disclosed
  Employee Stock Options would have been entitled to receive
  upon  consummation  of  the  Merger  if  such  holder  had
  exercised  such option immediately prior to, or coincident
  with,  the  Merger.    Tidewater   agrees   to  honor  the
  obligations of Hornbeck under such plans effective  as  of
  the Effective Time.

       Section  6.11  Exercise of North  Sea  Options.   The
  parties  agree and acknowledge that Hornbeck, as an equity
  owner of Ravensworth,  Seaboard  and  HOL, owns options to
  acquire   additional  equity  interests  in   Ravensworth,
  Seaboard and  HOL  that  expire  on  various  dates.   The
  parties  agree that Hornbeck shall not exercise, modify or
  cancel such  options  without the prior written consent of
  Tidewater, provided that Hornbeck shall have the right, on
  or after February 29, 1996,  to exercise, modify or cancel
  either or both of the Ravensworth Options after consulting
  with Tidewater, and provided further  that  from  February
  29,  1996 until the Closing Date, Hornbeck will not  issue
  Hornbeck Common Stock as consideration for the exercise of
  such options  without  Tidewater's  prior written consent.
  In the event the Ravensworth Option that  expires on March
  31, 1996 is not exercised by such date, thereby triggering
  mutual rights on behalf of Hornbeck and the 50.1% owner of
  Ravensworth to initiate a sale of Ravensworth, the parties
  agree that Hornbeck will not initiate such  a sale without
  the consent of Tidewater, or take any act with  respect to
  an offer for Ravensworth upon the initiation of a  sale by
  the  other  owner  of  Ravensworth without consulting with
  Tidewater;  provided  that  the  failure  by  Hornbeck  to
  exercise  such  Ravensworth   Option  will  not  alone  be
  construed to be an initiation by Hornbeck of such a sale.

       Section 6.12  Hornbeck 1995 Form 10-K.  (a)  Hornbeck
  agrees to use its best efforts to prepare  and  file  with
  the SEC its annual report on Form 10-K for the fiscal year
  ending December 31, 1995 before the Closing Date.

            (b)   Tidewater  agrees  to  cooperate  in  such
  filing of Hornbeck's Annual Report on Form 10-K.

       Section  6.13  Severance  Policy.  Hornbeck agrees to
  comply  with, and Tidewater agrees to honor, the terms  of
  the severance  policy  for  Hornbeck's  employees that was
  adopted by Hornbeck's Board of Directors  on  December 14,
  1995,  substantially  in  the  form  set forth on Schedule
  6.13.

       Section 6.14  Sub Stockholder Approval. Tidewater, as
  the  sole  stockholder  of  Sub,  shall  take  all  action
  necessary to effect the necessary stockholder approval  by
  Sub of this Agreement.

       Section  6.15  Employee  Indemnification.    Hornbeck
  shall,  at  its  next  Board  of Directors meeting but not
  later than January 31, 1996, amend that certain resolution
  adopted by the Hornbeck Board of Directors on November 19,
  1995 to limit its application to  the  matter disclosed in
  the first paragraph of Schedule 4.23(b).

       Section 6.16  Change in Control Agreements.  Hornbeck
  agrees that the  four  officers  of  Hornbeck  entitled to
  payments  under those certain Change in Control Agreements
  entered into  on  June  20, 1995, shall not be entitled to
  payments under Section 9(b)(iii)  of  such  agreements  in
  excess  of the amounts listed opposite each such officer's
  name on Schedule  6.16 provided however that the foregoing
  does not limit in any  way  the  obligations  of  Hornbeck
  pursuant  to the other provisions of the Change in Control
  Agreements.    Tidewater   agrees   to   cause   Surviving
  Corporation  to  honor such agreements in accordance  with
  their terms.

  ARTICLE 8.  POST-CLOSING COVENANTS

       Section 8.1 Use of Hornbeck Name. Tidewater shall use
  its  reasonable best efforts (a) to  remove  the  Hornbeck
  name and any abbreviation thereof and any associated trade
  or service marks from all vessels, real property, owned or
  leased,  and  equipment  upon  consummation  of the Merger
  (provided  that,  to  the  extent  any  such  vessels   or
  equipment  are  owned  or operated by the North Sea Group,
  Tidewater  shall  not  be deemed  to  have  breached  this
  covenant if it is prevented  from  effecting such removal)
  and  (b) to take all other steps reasonably  necessary  to
  avoid  any  public  use of the Hornbeck name in connection
  with the operation of  its business following the Closing,
  including  the  removal of  the  Hornbeck  name  from  the
  corporate or other  organizational  name of the members of
  the Hornbeck Group (provided that, with respect to members
  of the North Sea Group, Tidewater shall  not  be deemed to
  have  breached  this  covenant  if  it  is prevented  from
  effecting  such  removal),  in  each  case  as   soon   as
  practicable  but  in no event later than 60 days after the
  Closing Date.

       Section 8.2 Indemnification of Directors and Officers
  of Hornbeck.

            (a)   From and after the  Effective  Time of the
  Merger,  Tidewater  agrees to indemnify and hold harmless,
  and to cause Surviving  Corporation  to honor its separate
  indemnification  obligations  to, each person  who  is  an
  officer  or  director of Hornbeck  (or  a  member  of  the
  Hornbeck Group  serving at the request of Hornbeck) on the
  date of this Agreement or has served as such an officer or
  director at any time  since January 1, 1993 (together with
  those persons discussed  in  the  last  sentence  of  this
  subsection,  an "Indemnified Person") from and against all
  damages, liabilities,  judgments  and  claims (and related
  expenses  including, but not limited to,  attorney's  fees
  and amounts paid in settlement) based upon or arising from
  his or her  capacity as an officer or director of Hornbeck
  (or a member  of the Hornbeck Group serving at the request
  of Hornbeck), to the same extent he or she would have been
  indemnified under  the Certificate of Incorporation or By-
  laws of Hornbeck as  such  documents were in effect on the
  date of this Agreement.  Tidewater further agrees to honor
  the resolution regarding Hornbeck employee indemnification
  that  is referred to in Section  6.15  (but  only  to  the
  extent  such  resolution  has been modified as required by
  Section 6.15), to the extent the matter referred to in the
  first paragraph of Schedule  4.23(b) has not been resolved
  by the Closing Date.

            (b)   Tidewater  shall  pay  for  the  insurance
  premiums  required  for any extension  of  Hornbeck's  D&O
  insurance  policy  following   the   Closing  Date  for  a
  "discovery"  period  elected under such  insurance  policy
  covering the officers  and  directors  of  Hornbeck  (or a
  member  of  the  Hornbeck Group, serving at the request of
  Hornbeck), for a period  of  six  years  or  shall provide
  comparable coverage for the same period under  Tidewater's
  D&O  insurance  policy  for all directors and officers  of
  Hornbeck (or a member of  the  Hornbeck  Group, serving at
  the request of Hornbeck), covered by Hornbeck's policy.

            (c)   The  rights  granted  to  the  Indemnified
  Persons hereby shall be contractual rights  inuring to the
  benefit of all Indemnified Persons and shall  survive this
  Agreement  and any merger, consolidation or reorganization
  of Tidewater.

            (d)   The  rights  to indemnification granted by
  this Section 8.2 are subject to the following limitations:
  (i) the total aggregate indemnification  to be provided by
  Tidewater  and/or Surviving Corporation pursuant  to  this
  Section 8.2  will not exceed, as to all of the Indemnified
  Persons described  herein  as  a  group,  the  sum  of $50
  million, and Tidewater shall have no responsibility to any
  Indemnified  Person  for  the  manner in which such sum is
  allocated among that group (but  the  Indemnified  Persons
  may  seek  reallocation  among  themselves);  (ii) amounts
  otherwise  required  to  be  paid  by   Tidewater   to  an
  Indemnified  Person pursuant to this Section 8.2 shall  be
  reduced by any  amounts  that  such Indemnified Person has
  recovered by virtue of the claim for which indemnification
  is  sought  and  Tidewater  shall be  reimbursed  for  any
  amounts  paid by Tidewater that  such  Indemnified  Person
  subsequently  recovers  by  virtue of such claim; (iii) no
  Indemnified  Person shall be entitled  to  indemnification
  for any claim made or threatened prior to the Closing Date
  of which such Indemnified Person or Hornbeck was aware but
  did  not promptly  disclose  to  Tidewater  prior  to  the
  execution  of  this  Agreement, if the claim or threatened
  claim was known on or  before  such  time, or prior to the
  Closing Date, if such claim became known  after  execution
  of this Agreement, provided that all matters disclosed  in
  the  Schedules  to  this Agreement shall be deemed to have
  been disclosed to Tidewater  by  all  of  such Indemnified
  Persons  for  purposes  of this Section 8.2(d);  (iv)  any
  claim for indemnification  pursuant  to  this  Section 8.2
  must  be  submitted  in  writing  to  the  Chief Executive
  Officer of Tidewater promptly upon such Indemnified Person
  becoming aware of such claim and, in no event,  more  than
  ten  years from the Effective Date, provided that any such
  failure  to  advise  promptly  has a prejudicial effect on
  Tidewater; and (v) an Indemnified  Person shall not settle
  any  claim for which indemnification  is  provided  herein
  without the prior written consent of Tidewater.

            (e)   Tidewater  agrees that the indemnification
  limit set forth in subparagraph  (d)(i)  above  shall  not
  apply  to  any  damages, liabilities, judgments and claims
  (and  related  expenses,  including  but  not  limited  to
  attorney's fees and amounts paid in settlement) insofar as
  they arise out of  or  are  based upon any misstatement by
  Tidewater of a material fact in the Registration Statement
  or are based upon an omission  by  Tidewater of a material
  fact required to be stated therein,  or necessary in order
  to  make  a statement therein not misleading  unless  such
  statement or  omission was based upon information supplied
  by Hornbeck for inclusion therein.

       Section  8.3  Publication  of  Post-Merger   Results.
  Tidewater  shall use its reasonable best efforts to  cause
  financial results  covering  at least thirty days of post-
  Merger combined operations to  be  published  as  soon  as
  practicable after the passage of such thirty day period.

       Section  8.4  Employee   Benefits.    Following   the
  consummation  of  the  Merger,  Tidewater shall arrange to
  make generally available to the employees  of Hornbeck the
  benefits  listed  on Schedule 8.4 in accordance  with  the
  terms of such benefit  plans,  policies  or  arrangements,
  provided  that this covenant shall not prohibit  Tidewater
  from modifying  or  rescinding such benefits thereafter to
  the extent such modification  or  rescission  is generally
  applicable to Tidewater employees.

       Section 8.5  Registration Rights. Tidewater shall use
  its  reasonable  best  efforts  to  cause  a  Registration
  Statement  on  Form S-8 to be filed with the SEC  covering
  the shares of Tidewater  Common  Stock  to  be issued upon
  exercise of the Hornbeck Disclosed Employee Stock  Options
  (provided that no representation is made by Tidewater that
  any such Form S-8 Registration Statement will in all cases
  be available to permit resales of Tidewater Common Stock),
  or shall provide the holder of such options with piggyback
  registration rights for such shares.


  ARTICLE 9.  TERMINATION

       Section 9.1  Termination.    This  Agreement  may  be

  been a material breach by  the other of any representation
  or warranty contained in this Agreement or of any covenant

  shall not extend beyond the date set forth in subparagraph
  (c) below.

            (c)   Abandonment.  By the Board of Directors of

  (ii) any such condition cannot be met by such date and has
  not  been  waived  by  each  party  in  whose  favor  such
  condition inures, or (iii) the  Merger has not occurred by
  such date; provided, however, that  neither  Hornbeck  nor
  Tidewater  shall  be  entitled to terminate this Agreement
  pursuant to this subparagraph  (c)  if  such  party  is in
  willful   and   material   violation   of   any   of   its
  representations,   warranties   or   covenants   in   this
  Agreement.

            (d)   Lack   of   Approval.   By  the  Board  of
  Directors of either Hornbeck or Tidewater, if any required

  required   vote  at  the  Special  Meeting   of   Hornbeck
  stockholders or at any adjournment thereof.

            (e)   Government  Action.   If  any governmental

  nonappealable.

            (f)   Termination   Fee.   Hornbeck's  Board  of
  Directors may terminate this Agreement  in accordance with

  the amount of $6 million (the "Termination Fee"), no later

  obligation   of   or  liability  to  any  party  or  their
  respective  directors,   officers,  employees,  agents  or
  shareholders, unless such termination was the result of an
  intentional  breach  of any  representation,  warranty  or
  covenant in this Agreement  in  which  case  the party who
  breached the representation, warranty or covenant shall be
  liable to the other party for damages, and all  costs  and
  expenses  incurred  in  connection  with  the preparation,

  construed  as  constituting,  separate  representations or
  warranties  of  the  party to which such Schedules  relate
  except as and to the extent  provided  in  this Agreement.
  Inclusion  of  information in the Schedules shall  not  be
  construed  as  an   admission  that  such  information  is
  material for purposes  of  the specific provisions of this
  Agreement to which such information  relates.  Information
  included in the Schedules that is not  required  to  be so

  will otherwise remain in full force and effect.

       Section 10.6  Amendment   and   Modification.    This
  Agreement  may  be  amended  or modified only  by  written

  insist upon strict adherence to any term of this Agreement
  on  any  occasion  shall  not  be  considered  a waiver or
  deprive that party of the right thereafter to insist  upon
  strict  adherence  to  that term or any other term of this
  Agreement.  No waiver of  any  breach  of  this  Agreement
  shall  be  held  to  constitute  a waiver of any other  or
  subsequent breach.  Any waiver must be in writing.

  hereto  and their respective successors and assigns  (and,

  Warranties;  Remedies.   None of the  representations  and
  warranties  in  this  Agreement   or   in  any  instrument
  delivered pursuant hereto shall survive  the  consummation
  of  the  Merger.   Each party hereby agrees that its  sole
  right  and  remedy  with   respect  to  any  breach  of  a
  representation or a warranty  by  the other party shall be
  to  not consummate the transactions  described  herein  if
  such  breach results in the nonsatisfaction of a condition
  set forth  in  Section  7.2(a) or 7.3(a) hereof; provided,
  however, that the foregoing  shall  not  be deemed to be a
  waiver   of  any  claim  for  intentional  breach   of   a
  representation,  warranty or covenant of this Agreement or
  for fraud.

       IN WITNESS WHEREOF,  the  parties  hereto  have  duly
  executed  this  Agreement  as  of  the  date first written

Members of the Board:

     You have requested the opinion of Simmons & Company International
("Simmons") as investment bankers as to the fairness, from a financial point
of view, to the holders of shares of common stock, par value $0.10 per share
(the "Company Common Stock"), of Hornbeck Offshore Services, Inc. (the
"Company") of the consideration to be received by such stockholders in the
proposed merger of the Company with Tidewater Expansion, Inc. (the "Sub"), a
wholly owned subsidiary of Tidewater Inc. ("Tidewater"), pursuant to the
Agreement and Plan of Merger (the "Agreement") to be executed by Tidewater,
the Sub, and the Company (the "Proposed Merger").

     As more specifically set forth in the Agreement, in the Proposed Merger
each issued and outstanding share of the Company Common Stock will be
converted into 0.667 (as it may be adjusted as provided herein, the "Exchange
Ratio") of a share of common stock, par value $0.10 per share, of Tidewater
(the "Tidewater Common Stock") provided that, if the Average Market Price (as
defined below) of a share of Tidewater Common Stock is less than $24.50 or
greater than $32.50, then the Exchange Ratio shall be equal to the Calculated
Ratio (as defined below), provided further that in no event shall the Exchange
Ratio be less than 0.60 or greater than 0.74. The Calculated Ratio is defined
as follows: (i) if the Average Market Price of a share of Tidewater Common
Stock is less than $24.50, the Calculated Ratio shall equal that number
obtained by dividing $16.34 by the Average Market Price; or (ii) if the
Average Market Price of a share of Tidewater Common Stock is greater than
$32.50, the Calculated Ratio shall equal that number obtained by dividing
$21.68 by the Average Market Price. If the Calculated Ratio is less than 0.60
or greater than 0.74, either the Company or Tidewater has the right to
terminate the Proposed Merger. The Average Market Price of the Tidewater
Common Stock is defined as the average of the daily closing sale prices of a
share of Tidewater Common Stock on the New York Stock Exchange as reported in
THE WALL STREET JOURNAL for the 10 consecutive trading days that end on the
second trading day prior to the closing of the Proposed Merger.

     Simmons, as a specialized energy-related investment banking firm, is
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, the management and underwriting of sales of equity
and debt to the public, and private placements of equity and debt. Simmons has
previously rendered investment banking services to the Company and Tidewater
in connection with a number of transactions for which Simmons received
customary compensation. In addition, in the ordinary course of business,
Simmons may actively trade the securities of the Company and Tidewater for its
own account and for the accounts of customers and, accordingly, may at any
time hold a long or short position in such securities.

     In connection with rendering its opinion, Simmons has reviewed and
analyzed, among other things, the following: (i) the Letter of Intent between
Tidewater and the Company dated November 19,

                                     B-1
<PAGE>
1995; (ii) the Agreement; (iii) the financial statements and other information
concerning the Company, including the Annual Reports on Form 10-K of the
Company for each of the years in the three-year period ended December 31,
1994, the Quarterly Reports on Form 10-Q of the Company for the quarters ended
March 31, 1995, June 30, 1995 and September 30, 1995, and the Current Reports
on Form 8-K of the Company related to events occurring on November 15, 1994,
as amended, June 20, 1995 and November 19, 1995; (iv) certain other internal
information, primarily financial in nature, concerning the business and
operations of the Company furnished by the Company for purposes of Simmons'
analysis; (v) certain publicly available information concerning the trading
of, and the trading market for, the Company Common Stock; (vi) certain
publicly available information concerning Tidewater, including the Annual
Reports on Form 10-K of Tidewater for each of the fiscal years in the
three-year period ended March 31, 1995, the Quarterly Reports on Form 10-Q of
Tidewater for the quarters ended June 30, 1995 and September 30, 1995, and the
Current Reports on Form 8-K related to events occurring on November 30, 1994,
as amended, and January 5, 1995; (vii) certain other internal information,
primarily financial in nature, concerning the business and operations of
Tidewater furnished by Tidewater for purposes of Simmons' analysis; (viii)
certain publicly available information concerning the trading of, and the
trading market for, Tidewater Common Stock; (ix) certain publicly available
information with respect to certain other companies that Simmons believes to
be comparable to the Company or Tidewater and the trading markets for certain
of such other companies' securities; (x) certain publicly available
information concerning the estimates of the future operating and financial
performance of the Company, Tidewater and the comparable companies prepared by
industry experts unaffiliated with either the Company or Tidewater; (xi)
certain publicly available information concerning the nature and terms of
certain other transactions considered relevant to the inquiry; and (xii) made
such other analyses and examinations as we have deemed necessary or
appropriate. Simmons has also met with certain officers and employees of the
Company and Tidewater to discuss the foregoing, as well as other matters
believed relevant to the inquiry.

     In arriving at its opinion, Simmons has assumed and relied upon the
accuracy and completeness of all of the financial and other information
provided by the Company and Tidewater, or publicly available, including,
without limitation, information with respect to asset conditions, liability
reserves and insurance coverages, and has not attempted independently to
verify any of such information. Pursuant to the Agreement, Simmons has also
assumed that the Proposed Merger will be treated for federal income tax
purposes as a reorganization within the meaning of Section 368 of the Internal
Revenue Code of 1986, as amended, and will be treated as a "pooling of
interests" for accounting purposes. Simmons has not conducted a physical
inspection of any of the assets, properties or facilities of the Company or
Tidewater, nor has Simmons made or obtained any independent evaluations or
appraisal of any of such assets, properties or facilities.

     In conducting its analysis and arriving at its opinion as expressed
herein, Simmons has considered such financial and other factors as it deemed
appropriate under the circumstances including, among others, the following:
(i) the historical and current financial position and results of operations of
the Company and Tidewater; (ii) the business prospects of the Company and
Tidewater; (iii) the historical and current market for the Company Common
Stock, for Tidewater Common Stock and for the equity securities of certain
other companies believed to be comparable to the Company or Tidewater; (iv)
the respective contributions in terms of various financial measures of the
Company and Tidewater to the combined company, and the relative pro forma
ownership of Tidewater after the Proposed Merger by the current holders of the
Company Common Stock and Tidewater Common Stock; and (v) the nature and terms
of certain other acquisition transactions that Simmons believes to be
relevant. Simmons has also taken into account its assessment of general
economic, market and financial conditions and its experience in connection
with similar transactions and securities' valuation generally. Simmons'

                                     B-2
<PAGE>
opinion necessarily is based upon conditions as they exist and can be
evaluated on, and on the information made available at, the date hereof.

     Simmons is acting as financial advisor to the Company in this transaction
and will receive a customary contingent fee for its services.

     Based upon and subject to the foregoing, Simmons is of the opinion, as
investment bankers, that the consideration to be received by the holders of
the Company Common Stock in the Proposed Merger is fair to such holders from a
financial point of view.

                                          Sincerely,
                                          SIMMONS & COMPANY INTERNATIONAL

Members of the Board:

Reference is made to our letter dated December 21, 1995 with respect to the
fairness of the proposed merger of Hornbeck Offshore Services, Inc., with a
wholly owned subsidiary of Tidewater Inc., a copy of which is attached.

This is to advise you that since the date of such letter, nothing has come to
our attention that would cause us to change the opinion expressed in our letter
dated December 21, 1995.

    Sincerely,

/s/ NICHOLAS L. SWYKA

                                   PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law (the "DGCL") authorizes
a court to award, or a corporation's board of directors to grant, indemnity to
directors and officers under certain circumstances for liabilities incurred in
connection with their activities in such capacities (including reimbursement for
expenses incurred). Section 102(b)(7) of the DGCL permits a provision in the
certificate of incorporation of each corporation organized thereunder, including
Tidewater, eliminating or limiting, with certain exceptions, the personal
liability of a director to the corporation or its shareholders for monetary
damages for certain breaches of fiduciary duty as a director. Article VIII of
Tidewater's By-laws provides that Tidewater shall indemnify any directors,
directors emeriti, officers, employees and agents who were or are parties to or
threatened to be made parties to any threatened, pending or completed action,
suit or proceeding for liabilities and expenses incurred by reason of their
actions in such capacities on behalf of Tidewater, provided that the party
seeking indemnification acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful; provided, however, that in the case of an
action or suit by or in the right of the corporation to procure a judgment in
its favor, no indemnification shall be made in respect of any claim, issue or
matter as to which such party shall have been adjudged to be liable to the
corporation unless and only to the extent that an appropriate court shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such party is fairly and reasonably
entitled to indemnity for such expenses that the court shall deem proper.
Tidewater's By-laws also state, among other things, that it is the policy of
Tidewater to indemnify directors, directors emeriti, officers, agents and
employees of Tidewater to the fullest extent permitted by law. In addition,
Tidewater maintains an insurance policy designed to reimburse Tidewater for any
payments made by it pursuant to the foregoing indemnification. Such policy has
coverage of $15 million, subject to a $5 million self-insured retention.

registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

     (4)(a)  That prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is a part of this registration
statement, by any person or party who is deemed to be an underwriter within
the meaning of Rule 145(c), the issuer undertakes that such reoffering
prospectus will contain the information called for by the applicable
registration form with respect to reofferings by

                                     II-3
<PAGE>
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.

     (b)  That every prospectus (i) that is filed pursuant to paragraph (a)
immediately preceding, or (ii) that purports to meet the requirements of
Section 10(a)(3) of the Act and is used in connection with an offering of
securities subject to Rule 415, will be filed as a part of an amendment to the
registration statement and will not be used until such amendment is effective,
and that, for purposes of determining any liability under the Securities Act
of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

     (5)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions described under Item 20
above, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer
or controlling person of the registrant in the successful defense of any
action, suit, or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication
of such issue.
