                               PROSPECTUS SUMMARY
 
   
     The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and consolidated financial
statements (including the notes thereto) appearing elsewhere in this Prospectus.
Except as otherwise indicated, all information in this Prospectus assumes no
exercise of the Underwriters' over-allotment option. The Pro Forma Condensed
Consolidated Financial Statements and other pro forma operating data included in
this Prospectus give effect to the IPO, the repayment of certain indebtedness
with proceeds of the IPO, and the acquisition of the OMI Chemical Carriers, the
Seal Fleet Vessels, and vessels from GBMS (as each such term is defined herein)
and one additional vessel but do not give effect to the Current Acquisitions (as
defined herein) or the Offering. Unless the context otherwise requires, all
references in the Prospectus to the "Company" or "Hvide" include Hvide Marine
Incorporated, its predecessors, and its consolidated subsidiaries. See
"Glossary" for definitions of certain terms used herein.
    
 
                                  THE COMPANY
 
     Hvide (pronounced "vee-dah") provides marine support and transportation
services primarily in the U.S. domestic trade and principally to the energy and
chemical industries. The Company is the third largest operator of supply and
crew boats in the U.S. Gulf of Mexico. In addition, the Company is the sole
provider of commercial tug services in Port Everglades and Port Canaveral,
Florida, and a leading provider of such services in Mobile, Alabama. The Company
also transports petroleum products and specialty chemicals in the U.S. domestic
trade, a market insulated from international competition under the Jones Act.
The total capacity of the Company's five chemical carriers represents
approximately 44% of the capacity of the domestic specialty chemical carrier
fleet. In addition, the Company has options to acquire up to a 75% interest in
five double-hull petroleum product carriers currently under construction for
delivery during 1998.
 
     The Company has grown rapidly through a series of acquisitions, increasing
its marine support fleet from 20 vessels in 1993 to 74 vessels currently and its
marine transportation fleet from three vessels in 1993 to 29 vessels currently.
Primarily as a result of these acquisitions, the Company's revenue increased
196% from $41.5 million in 1993 to $123.0 million in 1995, on a pro forma basis.
Over the same period, the Company's EBITDA increased 181% from $11.3 million to
$31.7 million and its income from operations increased 186% from $6.6 million to
$18.9 million, in each case on a pro forma basis. For the nine months ended
September 30, 1996, the Company reported revenue, EBITDA, and operating income
of $101.0 million, $27.1 million, and $16.0 million, respectively, in each case
on a pro forma basis. For other measures of the Company's operating results as
determined under generally accepted accounting principles and its pro forma
operating results, see "Selected Historical and Pro Forma Consolidated Financial
Data" and the Company's consolidated financial statements.
 
     The Company has recently acquired or entered into agreements to acquire an
aggregate of seven supply boats, five crew boats, one offshore anchor handling
tug, and two harbor tugs (the "Current Acquisitions"). The Current Acquisitions,
which upon completion will increase the Company's marine support fleet from 74
to 89 vessels, will be funded in part with proceeds of the Offering. The $51.2
million aggregate cost of the Current Acquisitions includes the estimated cost
of upgrading, refurbishing, and lengthening two of the supply boats to 225-foot,
4,300-hp dynamically positioned vessels for use in deepwater service. See "Use
of Proceeds" and "Business -- Current Acquisitions."
 
     The Company's strategy is to realize the benefits presented by the
integration of its recent and pending acquisitions with its existing operations
and to continue to grow through selected acquisitions that further consolidate
the marine support and transportation services markets in which the Company
operates. The Company believes it has numerous opportunities to make further
accretive acquisitions in its core businesses. Critical elements of the
Company's strategy include continuing to (i) utilize its demonstrated expertise
in acquiring vessels, thereby further consolidating its niche markets, (ii)
emphasize U.S. domestic operations, (iii) develop and apply marine technology to
meet its customers' needs in an innovative and cost-effective manner, (iv)
maintain and pursue long-term customer relationships that limit the risk
associated with the investments required for new vessels and mitigate the
effects of industry cyclicality, and (v) enhance its record of quality service
and safety.
 
MARINE SUPPORT SERVICES
 
     Offshore Energy Support. The Company's fleet of 75 offshore energy support
vessels, giving effect to the Current Acquisitions, consists of 31 supply boats,
42 crew boats, and two utility boats that transport supplies and personnel and
provide towing and other support services to offshore oil and natural gas
exploration and production operations, primarily in the U.S. Gulf of Mexico. The
offshore energy support industry in the U.S.
                                        3
<PAGE>   5
 
Gulf of Mexico has experienced substantial consolidation and vessel attrition
during the past decade. The Company believes that industry fundamentals have
improved, and expects continued strong demand and further consolidation to
result in increasing day rates and utilization. The Current Acquisitions
strengthen the Company's position as the third largest operator of supply and
crew boats in the U.S. Gulf of Mexico. This strengthened position will, at the
same time, make the Company's operations more susceptible to fluctuations in oil
and gas prices, which affect the level of offshore exploration and development
activity and thus the demand for the services provided by the Company's offshore
energy support vessels. In the past, the Company has sought to mitigate the
adverse effect of reduced demand through cost reduction and relocation of
support vessels to other markets. See "Risk Factors -- Cyclical Industry
Conditions" and "Business -- The Industry -- Marine Support Services."
 
     Offshore and Harbor Towing. The Company's 14 tugs, giving effect to the
Current Acquisitions, provide offshore towing services and harbor assistance to
tankers, barges, containerships, other cargo vessels, and cruise ships calling
at Port Everglades and Port Canaveral, Florida, and Mobile, Alabama. In Port
Everglades and Port Canaveral, the Company is the sole franchisee providing
commercial tug services. The Company directed the design and construction of its
technologically advanced 5,100-hp tractor tug, the Broward, which is capable of
providing escort services to tankers and other large vessels and specialized
deepwater services to the offshore energy industry. In addition to these 14
tugs, the Company recently entered into one-year charters of two newly built
4,000-hp tugs with omni-directional propulsion systems, which are currently
being used by the Company to provide harbor services. The Company intends to
remove from service one tug currently engaged in harbor services in the second
quarter of 1997.
 
MARINE TRANSPORTATION SERVICES
 
     Chemical Transportation. The total capacity of the Company's five chemical
carriers represents approximately 44% of the capacity of the domestic specialty
chemical carrier fleet, and four of the vessels are among the last independently
owned chemical carriers scheduled to be retired under the Oil Pollution Act of
1990 ("OPA 90"). Two of the carriers currently transport industrial chemicals in
bulk parcel lots, and the other three carriers currently transport petroleum
products and petrochemicals, primarily for major oil and chemical companies. The
Company believes that domestic energy and chemical transportation freight rates
will increase within the next three to five years and continue thereafter, as
the supply of vessels eligible to carry petroleum products diminishes as a
result of mandatory retirement imposed by OPA 90.
 
     Petroleum Product Transportation. The Company's petroleum product
transportation fleet is currently comprised of the Seabulk Challenger, a 39,300
dwt product carrier, and a fleet of ten towboats and 13 fuel barges. The Seabulk
Challenger has since 1975 operated under successive charters to Shell Oil
Company ("Shell") (extending to January 2000) carrying refined petroleum
products from Shell's refineries in Texas and Louisiana to various U.S. Gulf of
Mexico and Atlantic coast ports. The towboat and barge fleet is engaged in the
transportation of residual and diesel fuels along the Atlantic intracoastal
waterway and in the St. Johns River in Florida, primarily for a major Florida
utility.
 
     The Company also owns a minority interest in five 45,300 dwt double-hull
petroleum product carriers currently under construction for delivery during
1998. The product carriers are intended to serve the domestic market currently
served by single-hull tankers whose retirement is mandated by OPA 90. The
Company, whose ownership is currently 2.4%, has options to purchase up to an
additional 72.6% ownership interest in the vessels for a total estimated cost of
up to $32.0 million (assuming exercise of the options before January 1, 1998).
The Company is supervising the construction of the vessels and will provide
operational management following delivery.
 
     OPA 90. OPA 90 requires, among other things, that existing single-hull
vessels be retired from domestic transportation of petroleum products between
1995 and 2015, depending upon vessel size and age, unless retrofitted with
double hulls. The Company's chemical carriers and its petroleum product carrier
will be required to cease transporting petroleum products at various dates from
2000 to 2015, and its fuel barges will cease transporting fuel in 2015. See
"Risk Factors -- Mandated Removal of Vessels from Jones Act Trade." The Company
currently has no specific plans concerning the retrofitting or replacement of
such vessels.

                      SUMMARY CONSOLIDATED HISTORICAL AND
                     PRO FORMA FINANCIAL AND OPERATING DATA
 
     The summary consolidated financial data presented below should be read in
conjunction with the consolidated financial statements and notes thereto of the
Company, the financial statements and notes thereto of the OMI Chemical
Carriers, the Seal Fleet Vessels, and GBMS, "Selected Historical and Pro Forma
Consolidated Financial Data," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," and "Pro Forma Condensed Consolidated
Financial Statements" included elsewhere in this Prospectus. The summary
unaudited pro forma statement of operations data for the year ended December 31,
1995 and the nine months ended September 30, 1996 give effect to the
acquisitions of the three OMI Chemical Carriers and the eight Seal Fleet Vessels
in August 1996, the acquisition of eight crew boats from GBMS in January 1996,
the acquisition of one vessel in February 1996, the August 1996 initial public
offering of the Company's Class A Common Stock (the "IPO"), and the repayment of
certain indebtedness, as if all such transactions had occurred on January 1,
1995 and January 1, 1996, respectively. Such pro forma data are presented for
illustrative purposes only and do not purport to represent what the Company's
results actually would have been if such events had occurred at the dates
indicated, nor do such data purport to project the results of operations for any
future period or as of any future date. The summary unaudited pro forma
statements of operations data for the year ended December 31, 1995 and the nine
months ended September 30, 1996 do not give effect to the Current Acquisitions
or the Offering. The summary balance sheet data at September 30, 1996 have been
adjusted to give effect to the Offering and the application of the estimated net
proceeds therefrom. The results for the nine months ended September 30, 1996 are
not necessarily indicative of the results to be expected for the full year.

    income tax expense, depreciation expense, amortization expense, minority
    interests, and other non-operating income) is frequently used by securities
    analysts and is presented here to provide additional information about the
    Company's operations. EBITDA is not required by generally accepted
    accounting principles and should not be considered as an alternative to net
    income as an indicator of the Company's operating performance or as an
    alternative to cash flows from operations as a measure of liquidity.
 
(5) For the years 1994 and 1995 and the nine months ended September 30, 1995 and
    1996, the crew boat vessel data include two utility boats. However, the crew
    boat operating data exclude the results of the two utility boats.
 
(6) Average day rates are calculated based on vessels operating domestically by
    dividing total vessel revenue by the total number of days of vessel
    utilization.
 
(7) Utilization is based on vessels operating domestically and determined on the
    basis of a 365-day year. Vessels are considered utilized when they are
    generating charter revenue.
 
(8) Time charter equivalents are calculated by deducting total voyage expenses
    from total voyage revenue and dividing the result by the total days per
    voyage.

                                  RISK FACTORS
 
     In addition to other information contained in this Prospectus, prospective
purchasers of the Class A Common Stock should carefully consider the following
factors in evaluating an investment in the Company.
 
POTENTIAL LOSS OF JONES ACT PROTECTION
 
     Most of the Company's operations are conducted in the U.S. domestic trade,
which, by virtue of the U.S. coastwise laws (often referred to as the "Jones
Act"), is restricted to vessels built in the United States, owned and crewed by
U.S. citizens, and registered under U.S. law. There have been repeated attempts
to repeal the coastwise laws, and efforts to effect such repeal are expected to
continue in the future. The Company is already subject to vigorous competition
and potential additional competition in all aspects of its operations, including
competition by companies with financial resources greater than those of the
Company which could be committed to the construction of new vessels in excess of
market requirements. Repeal of the coastwise laws would result in additional
competition from vessels built in lower-cost foreign shipyards and manned by
foreign nationals accepting lower wages than U.S. citizens and could have a
material adverse effect on the Company.
 
HAZARDOUS ACTIVITIES
 
     The operation of ocean-going vessels carries an inherent risk of
catastrophic marine disasters and property losses caused by adverse weather
conditions, mechanical failures, human error, and other circumstances or events.
In addition, the transportation of petroleum and toxic chemicals is subject to
the risk of spills and environmental damage. Any such event could have a
material adverse effect on the Company. While the Company carries insurance to
protect against most of the accident-related risks involved in the conduct of
its business, including environmental damage and pollution insurance coverage,
there can be no assurance that all risks are adequately insured against, that
any particular claim will be paid, or that the Company will be able to procure
adequate insurance coverage at commercially reasonable rates in the future. In
particular, more stringent environmental regulations may result in increased
costs for, or the lack of availability of, insurance against the risks of
environmental damage or pollution.
 
CYCLICAL INDUSTRY CONDITIONS
 
     Historically, the marine support and transportation services industry has
been cyclical, with corresponding volatility in profitability and vessel values.
This industry cyclicality has been due to changes in the level of general
economic growth as well as changes in the supply of and demand for vessel
capacity, which impact charter rates and vessel values. The supply of vessels is
influenced by the numbers of vessels constructed and retired and by government
and industry regulation of maritime transportation practices. The Company's
offshore energy support services and offshore and harbor towing services are
dependent upon the levels of activity in offshore oil and natural gas
exploration, development, and production. Such activity levels are affected by
both short- and long-term trends in world oil and natural gas prices.
Utilization of the Company's towboat and fuel barge fleet is also partly
dependent on such prices as well as energy utilization, which is partly a
function of the weather. In recent years, oil and natural gas prices, and
therefore the level of offshore drilling and exploration activity, have been
extremely volatile. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." Any future prolonged decline in natural
gas or oil prices will, in all likelihood, depress the level of offshore
exploration and development activity and result in a corresponding decline in
the demand for the services provided by the Company's offshore energy support
vessels, and any sustained reduction in such activity could have a material
adverse effect on the Company. See "Business -- The Industry -- Marine Support
Services -- Offshore Energy Support." In addition, marine support and
transportation services are dependent on general economic conditions. Any
general economic slowdown could have an adverse effect on the level of the
provision of those services and therefore upon the Company.
 
                                        8
<PAGE>   10
 
ENVIRONMENTAL RISK AND REGULATIONS
 
     Current laws and regulations could impose substantial liability on the
Company for damages, remediation costs, and penalties associated with oil or
hazardous-substance spills or other discharge into the environment involving the
Company's vessel operations. Shoreside industrial operations, including a small
marine maintenance and drydocking facility owned and operated by the Company,
are also subject to federal, state, and local environmental laws and
regulations. Amendment of these laws and regulations to impose more stringent
requirements would likely result in increased maintenance and operating
expenses. In addition, OPA 90 requires tanker owners and operators to establish
and maintain with the U.S. Coast Guard evidence of financial responsibility, as
demonstrated by a certificate of financial responsibility ("COFR"), with respect
to potential oil spill liability, which the Company and most of its competitors
currently satisfy by virtue of self-insurance or third-party insurance.
Additional laws and regulations may be adopted that could limit the ability of
the Company to do business or increase the cost of its doing business and could
have a material adverse effect on its operations. See "Business -- Environmental
and Other Regulation."
 
HIGH LEVERAGE AND DEBT SERVICE; CERTAIN RESTRICTIONS ON CAPITAL EXPENDITURES
 
   
     The Company will continue to have substantial indebtedness upon completion
of the Offering. After giving effect to the application of proceeds from the
Offering to repay certain indebtedness, the Company's total outstanding
indebtedness would have been $113.0 million as of September 30, 1996. In
addition, the Company has a minority interest, and options to acquire a majority
interest, in five vessels currently under construction that are being financed,
in substantial part, with non-recourse indebtedness. See "Business -- Company
Operations -- Marine Transportation Services -- Petroleum Product
Transportation." The Company's leverage poses certain risks for the Company,
including the risks that the Company may not generate sufficient cash flow to
service its indebtedness; that the Company will be unable to renegotiate the
terms of its indebtedness; that it may be unable to obtain additional financing
in the future; that, to the extent it is significantly more leveraged than its
competitors, it may be placed at a competitive disadvantage; and that the
Company's capacity to respond to market conditions and other factors may be
adversely affected. The Company's ability to service its debt will depend on its
future performance, which will be subject to prevailing economic and competitive
conditions and other specific factors discussed herein, as well as developments
in capital markets generally. The terms of the Company's Credit Facility (as
defined herein) (i) require the Company to maintain minimum levels of liquidity
and net worth and to meet specified financial ratios, (ii) limit the issuance of
debt by the Company and of debt or preferred stock by the Company's
subsidiaries, (iii) restrict the ability of its subsidiaries to pay dividends or
make distributions to the Company, (iv) restrict the Company's ability to pay
dividends, redeem capital stock or subordinated debt, make certain investments
or issue capital stock, place additional liens on its or its subsidiaries'
property, incur additional long-term indebtedness, make capital expenditures in
excess of specified limitations, and enter into mergers or similar transactions,
and (v) limit certain corporate acts and transactions by the Company. Such
provisions could adversely affect the Company's ability to pursue its strategy
of growth through acquisitions. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Financial
Resources" and "Description of Certain Indebtedness -- Credit Facility."
    
 
MANDATED REMOVAL OF VESSELS FROM JONES ACT TRADE
 
     OPA 90 establishes a phase-out schedule, depending upon vessel size and
age, for single-hull vessels carrying crude oil and petroleum products which, in
the case of the Company's petroleum products carrier (Seabulk Challenger) and
five chemical carriers (HMI Astrachem, Seabulk Magnachem, HMI Dynachem, HMI
Petrochem and Seabulk America), are the years 2003, 2000, 2007, 2011, 2011, and
2015, respectively; and in the case of its fuel barges is the year 2015. As a
result of this requirement, these vessels will be prohibited from transporting
petroleum products in U.S. waters after their respective phase-out dates. There
can be no assurance that future tanker market rates will be sufficient to
support construction of replacement vessels. Although the Company's remaining
vessels are not subject to mandatory retirement, and the Company employs what it
believes to be a rigorous maintenance program for all its vessels, there can be
no assurance that the Company will be able to maintain its fleet by extending
the economic lives of existing
 
                                        9
<PAGE>   11
 
vessels or acquiring new or used vessels. See "Business -- Company
Operations -- Marine Transportation Services" and "-- Environmental and Other
Regulation."
 
RELIANCE ON SIGNIFICANT CUSTOMERS
 
     Shell, Amoco Corporation ("Amoco"), Phillips Petroleum Company
("Phillips"), and Chevron Corporation ("Chevron") each accounted for between 5%
and 10% of the Company's revenue for the nine months ended September 30, 1996 on
a pro forma basis, and Shell and Phillips each accounted for between 5% and 10%
of the Company's revenue for the year ended December 31, 1995 on a pro forma
basis. The loss of any of these customers could have a material adverse effect
on the Company. See "Business -- Company Operations -- Customers and Charter
Terms."
 
RISK OF LOSS AND INSURANCE
 
     The business of the Company is affected by a number of risks, including the
mechanical failure of its vessels, collisions, vessel loss or damage, cargo loss
or damage, hostilities, and labor strikes. In addition, the operation of any
vessel is subject to the inherent possibility of a catastrophic marine disaster,
including oil, fuel, or chemical spills and other environmental mishaps, as well
as other liabilities arising from owning and operating vessels. Any such event
may result in loss of revenues and increased costs and other liabilities.
Although the Company's losses from such hazards have not historically exceeded
its insurance coverage, there can be no assurance that this will continue to be
the case.
 
     OPA 90, by imposing virtually unlimited liability upon vessel owners,
operators, and certain charterers for certain oil pollution accidents in the
United States, has made liability insurance more expensive and has also prompted
insurers to consider reducing available liability coverage. See
"Business -- Environmental and Other Regulation." While the Company maintains
insurance, there can be no assurance that all risks are adequately insured
against particularly in light of the virtually unlimited liability imposed by
OPA 90, that any particular claim will be paid, or that the Company will be able
to procure adequate insurance coverage at commercially reasonable rates in the
future. Because it maintains mutual insurance, the Company is subject to funding
requirements and coverage shortfalls in the event claims exceed available funds
and reinsurance and to premium increases based on prior loss experience. Any
such shortfalls could have a material adverse impact on the Company.
 
RESTRICTION ON FOREIGN OWNERSHIP
 
     In order to maintain the eligibility of the Company to operate vessels in
the U.S. domestic trade, 75% of the outstanding capital stock and voting power
of the Company is required to be held by U.S. citizens. See
"Business -- Environmental and Other Regulation." Although the Company's
Articles of Incorporation contain provisions limiting non-citizen ownership of
its capital stock (see "Description of Capital Stock -- Foreign Ownership
Restrictions"), the Company could lose its ability to conduct operations in the
U.S. domestic trade if such provisions prove unsuccessful in maintaining the
required level of citizen ownership. Such loss would have a material adverse
effect on the Company.
 
ACQUISITION STRATEGY
 
     One element of the Company's strategy is to continue to grow through
selected acquisitions that further consolidate the marine support and
transportation markets in which the Company operates. There can be no assurance
that each of the Current Acquisitions, certain of which are subject to
conditions precedent, will be completed or that the Current Acquisitions or any
additional acquisitions will be successful in enhancing the operations or
profitability of the Company; that the Company will be able to identify suitable
additional acquisition candidates; that it will have the financial ability to
consummate additional acquisitions; or that it will be able to consummate such
additional acquisitions on terms favorable to the Company. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Financial Resources" and "Description of Certain
Indebtedness -- Credit Facility."
 
                                       10
<PAGE>   12
 
LEGAL PROCEEDINGS
 
     The Company's chemical carrier Seabulk America is the subject of two
pending legal proceedings, one involving the eligibility of the vessel to
operate in the U.S. domestic trade and the other involving the cost of its
completion, either of which, if determined adversely to the Company, could have
a material adverse effect on the Company. See "Business -- Legal Proceedings."
 
INTERNATIONAL MARINE OPERATIONS
 
     The Company operates three offshore supply boats in Southeast Asia, and one
each in Egypt and Cameroon. Such operations are subject to risks inherent in
conducting business in foreign countries, including political changes, possible
vessel seizure and asset nationalization, or other government actions, all of
which are beyond the control of the Company and the occurrence of any of which
could have a material adverse effect on the Company.
 
KEY PERSONNEL
 
     The Company is materially dependent upon the continued services of key
members of its management, including its Chairman, President, and Chief
Executive Officer, J. Erik Hvide. The loss of one or more key members of
management could have a material adverse effect on the Company. See
"Management."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     There may be significant volatility in the market price for the Company's
Class A Common Stock. Quarterly operating results of the Company, changes in
general conditions in the economy, the financial markets, or the marine support
and transportation services industry, or other developments affecting the
Company or its competitors, could cause the market price of the Company's Class
A Common Stock to fluctuate substantially. In addition, in recent years, the
stock market and, in particular, the marine support and transportation services
industry segment, has experienced significant price and volume fluctuations.
This volatility has affected the market prices of securities issued by many
companies for reasons unrelated to their operating performance. In addition, the
Company's operating results in future periods may be below the expectations of
securities analysts and investors. In such event, the price of the Class A
Common Stock would likely decline, perhaps substantially.
 
   
CONTROL BY CURRENT STOCKHOLDERS; SHAREHOLDERS AGREEMENT; RESTRICTIONS ON
CORPORATE ACTIONS; ANTI-TAKEOVER EFFECT OF DUAL CLASSES OF STOCK AND CERTAIN
OTHER PROVISIONS
    
 
   
     The Company's Common Stock is divided into Class A Common Stock, of which
each share is entitled to one vote with respect to all matters submitted to
stockholder vote, and Class B Common Stock, of which each share is entitled to
ten votes with respect to such matters. Upon completion of the Offering, J. Erik
Hvide and the Hvide Trusts will beneficially own 4,000 shares of Class A Common
Stock and 1,769,107 shares of Class B Common Stock, and the Investor Group will
beneficially own 219,850 shares of Class A Common Stock and 1,650,470 shares of
Class B Common Stock. Upon completion of the Offering, Mr. Hvide (together with
the Hvide Trusts) and the Investor Group will therefore own shares that will
represent 11.9% and 12.5%, respectively, of the outstanding shares of Common
Stock (11.3% and 12.0%, respectively, if the Underwriters' over-allotment option
is exercised in full) and 38.7% and 36.6%, respectively, of the voting power of
all Common Stock (37.9% and 36.3%, respectively, if the Underwriters'
over-allotment option is exercised in full). Accordingly, Mr. Hvide and the
Investor Group will be able to elect a majority of the Company's directors and
to determine the disposition of all matters submitted to a vote of the Company's
stockholders. In addition, the Hvide Family and the Investor Group have entered
into an agreement giving them the right to nominate eight and three persons,
respectively, to the Company's 11-member Board of Directors. Each share of Class
B Common Stock is convertible by its holder into one share of Class A Common
Stock at any time, and automatically converts into Class A Common Stock if held
by persons other than the Hvide Family and members of the Investor Group. See
"Management" and "Description of Capital Stock -- Certain Provisions of Articles
of Incorporation and Bylaws." Pursuant to certain agreements, Mr. Hvide and the
Hvide Trusts
    
 
                                       11
<PAGE>   13
 
   
will be required to transfer shares of Common Stock to the Company upon its
issuance of shares of Common Stock to the Investor Group on June 10, 1997. See
"Description of Capital Stock -- Contingent Share Issuance Agreement." In
addition, so long as the Investor Group owns specified percentages of the
outstanding Class B Common Stock, certain significant transactions will require
the approval of 95%, and the appointment of a new chief executive officer will
require approval of 75%, of the holders of the Class B Common Stock. See
"Description of Capital Stock -- Certain Provisions of Articles of Incorporation
and Bylaws."
    
 
   
     Such control by Mr. Hvide and the Investor Group may also have the effect
of discouraging certain types of transactions involving an actual or potential
change of control of the Company, including transactions in which the holders of
Class A Common Stock might otherwise receive a premium for their shares over
then-current market prices. In addition, pursuant to the Company's Articles of
Incorporation, the Board of Directors is divided into three classes of directors
serving staggered three-year terms and, consequently, it would likely require
two annual meetings rather than one for the stockholders to replace a majority
of the Board of Directors.
    
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Sales of substantial amounts of Class A Common Stock in the public market,
or the perception that such sales may occur, could have an adverse effect on the
market price of the stock. Subject to an agreement that restricts their sale for
90 days following the date of this Prospectus, all 1,531,466 of the shares of
Class B Common Stock owned by Mr. Hvide and the Hvide Trusts will be eligible
for public sale (Class B Common Stock is freely convertible, share for share,
into Class A Common Stock), subject to volume and other limitations of Rule 144
under the Securities Act of 1933, as amended (the "Securities Act"). Subject to
an agreement that restricts their sale prior to August 7, 1997 without the prior
approval of the Representatives of the Underwriters, 1,870,320 shares of Common
Stock owned by the Investor Group will be eligible for public sale under Rule
144 or through the exercise of demand registration rights. Pursuant to the
Shareholders Agreement and CSI Agreement (each as defined herein) Mr. Hvide and
the Hvide Trusts will be required to transfer shares of Common Stock to the
Company upon its issuance of shares of Common Stock to the Investor Group on
June 10, 1997. Such shares may become eligible for public sale under Rule 144.
The Company has granted the Investor Group certain registration rights under the
Securities Act with respect to the Common Stock owned by them. See "Description
of Capital Stock -- Shareholders Agreement" and " -- Contingent Share Issuance
Agreement." Certain directors, officers, and employees of the Company hold
options to purchase 806,000 shares of Class A Common Stock at an exercise price
of $12 per share. See "Shares Eligible for Future Sale." Moreover, the Company
may issue shares of Common Stock in connection with future acquisitions. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" and "Business -- Strategy."
    
 
FORWARD-LOOKING INFORMATION
 
     Certain statements and information in this Prospectus constitute forward
looking statements within the meaning of the Federal Private Securities
Litigation Reform Act of 1995. Such forward looking statements are typically
punctuated by words or phrases such as "anticipate," "estimate," "projects,"
"management believes," "the Company believes," and words or phrases of similar
import. Such statements are subject to certain risks, uncertainties, or
assumptions. Should one or more of these risks or uncertainties materialize, or
should underlying assumptions prove incorrect, actual results may vary
materially from those anticipated, estimated, or projected. Among the key
factors that may have a direct bearing on the Company's results and financial
condition are: (i) competitive practices in the marine support and
transportation industry in which the Company competes, (ii) fluctuations in oil
and gas prices, (iii) environmental liabilities to which the Company may become
subject in the future which are not covered by an indemnity or insurance, (iv)
the impact of current and future laws and governmental regulations (particularly
coastwise and environmental laws and regulations) affecting the marine support
and transportation industry in general and the Company's operations in
particular, (v) risks relating to the Company's high leverage position and
potential inability to service its debt, (vi) risks related to the mandated
removal of the Company's vessels from the Jones Act trade, (vii) risks related
to the Company's reliance on significant customers, and (viii) risks related to
the outcome of pending legal proceedings.

                                  THE COMPANY
 
     Hvide Marine Incorporated was incorporated in Florida in 1994 as Hvide
Corp., the holding company for its principal operating subsidiary. Immediately
prior to the August 1996 closing of the IPO, the principal operating subsidiary
was merged with and into Hvide Corp., which was renamed Hvide Marine
Incorporated. The Company began operations in 1958 as a harbor tug operator and
in 1975 acquired its first petroleum product carrier. It began transporting
specialty chemicals in 1977 and expanded into the operation of offshore energy
support vessels with the acquisition of eight supply boats in 1989.
 
   
     In 1994, the Company substantially expanded its fleet, adding 20 crew
boats, six supply boats, and two utility boats to its offshore energy support
fleet and an 18-vessel tug and barge fleet to its petroleum product
transportation operations. This expansion also included the acquisition of the
minority interests in certain vessels that were majority owned by the Company.
These acquisitions were financed primarily through borrowings under a Credit
Agreement, dated as of September 28, 1994, by and among the Company, Citibank,
N.A., as Administrative Agent and Co-Agent, The First National Bank of Boston,
as Letter of Credit Agent and Co-Agent, and the lending banks parties thereto
(as amended, the "Credit Facility") and the issuance of debt and equity
securities of the Company to the Investor Group for aggregate proceeds of $50.0
million. The Selling Stockholders are members of the Investor Group. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources," "Certain Transactions,"
"Principal and Selling Stockholders," and "Description of Capital
Stock -- Contingent Share Issuance Agreement."
    
 
     Further substantial fleet expansions occurred in 1996. In January 1996, the
Company acquired eight crew boats from GBMS, and in August 1996, in transactions
with five different sellers (the "August 1996 Acquisitions"), it acquired three
chemical carriers, ten offshore supply boats, and one crew boat. The aggregate
purchase price of the August 1996 Acquisitions was $97.5 million, consisting of
$35.5 million in cash, funded primarily with proceeds of the IPO, and the
assumption or incurrence of $62.0 million of debt obligations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources."
 
     The Company has recently acquired or entered into agreements to acquire an
aggregate of seven supply boats, five crew boats, one offshore anchor handing
tug, and two harbor tugs which constitute the Current Acquisitions. The Current
Acquisitions, which will increase the Company's marine support fleet from 74 to
89 vessels, will be funded, in part, with proceeds of the Offering. The $51.2
million aggregate cost of the Current Acquisitions includes the estimated $6.9
million cost of upgrading, refurbishing, and lengthening two of the supply boats
to 225-foot, 4,300-hp dynamically positioned vessels for use in deepwater
service. See "Use of Proceeds" and "Business -- Current Acquisitions."
 
     The Company's principal office is located at 2200 Eller Drive, Fort
Lauderdale, Florida 33316, and its telephone number is (954) 523-2200.

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the Class A Common Stock
offered hereby, assuming a public offering price of $25 1/4 per share (the last
reported sale price of the Class A Common Stock on the Nasdaq National Market on
January 27, 1997) and after deducting underwriting discounts and commissions and
estimated offering expenses, are estimated to be approximately $91.4 million
($105.7 million if the Underwriters' over-allotment option is exercised in
full). Of such net proceeds, (i) approximately $35.6 million will be used to
fund the balance of the aggregate $51.2 million purchase price for the Current
Acquisitions, which includes $6.9 million that will be used to upgrade,
refurbish, and lengthen two of the vessels included in the Current Acquisitions,
(ii) approximately $36.3 million will be used to repay certain outstanding
indebtedness as described below, and (iii) the balance of approximately $19.5
million will be used for general corporate purposes. For information concerning
the acquisitions to be funded with a portion of the proceeds of the Offering,
see "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business -- Current Acquisitions."
    
 
   
     Of the $36.3 million to be used to repay outstanding indebtedness, (i)
$10.2 million will be used to repay $0.4 million of accrued interest on and $9.8
million of principal of the Senior Notes (as defined herein), which mature in
two equal installments in September 2003 and 2004 and bear interest at the rate
of 12% per annum, (ii) $10.0 million will be used to repay the amount
outstanding under the revolving line of credit under the Credit Facility, which
line is due in January 2001 and bears interest at a fluctuating rate (7.9% at
September 30, 1996), (iii) $13.5 million will be used to repay the amount
outstanding under the vessel acquisition credit line under the Credit Facility,
(iv) $2.0 million will be used to repay accrued interest on and the outstanding
principal of the Founder's Note (as defined herein), which is due in 2000 and
bears interest at the greater of 12% per annum or prime plus 3% (12% at
September 30, 1996), and (v) $0.6 million will be used to repay interest on and
the outstanding principal of the HOS Notes and the HCL Notes (each as defined
herein) which are due in 2004 and bear interest at 12% per annum. For additional
information concerning the indebtedness that is being repaid with a portion of
the proceeds from the Offering, see "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources," "Certain Transactions," and "Description of Certain
Indebtedness -- Credit Facility."
    
 
   
     To the extent that the Underwriters' over-allotment option is exercised for
more than 25,000 shares of Class A Common Stock, the net proceeds therefrom will
be used for general corporate purposes, which may include the repayment of
indebtedness, vessel acquisitions, and vessel improvements. Pending the use of
proceeds as described above, the Company intends to place such net proceeds in
interest-bearing accounts or invest such proceeds in short-term,
interest-bearing, investment-grade securities.
    
 
     The Company will not receive any proceeds from the sale of Class A Common
Stock by the Selling Stockholders or the Hvide Family Trust II.
 
                    PRICE RANGE OF THE CLASS A COMMON STOCK
 
     Since August 9, 1996, the Class A Common Stock has been traded on the
Nasdaq National Market under the symbol "HMAR." The following table sets forth

                                DIVIDEND POLICY
 
     The Company has not paid any cash dividends on its Common Stock since its
formation. It presently intends to retain its earnings for use in its business
and therefore does not anticipate paying any cash dividends in the foreseeable
future. The payment of any future dividends will be determined by the Board of
Directors in light of conditions then existing, including the Company's
earnings, financial condition and requirements, restrictions in financing
agreements, business conditions, and other factors. The Company's ability to pay
dividends also is dependent upon the earnings of its subsidiaries and the
distribution of those earnings to the Company and loans or advances by the
subsidiaries to the Company. The ability of the subsidiaries to pay dividends or
to make distributions is restricted by the terms of the Credit Facility. So long
as such restrictions remain in effect, the Company is not expected to have
access to the cash flow generated by its subsidiaries. In addition, the
Company's ability to pay dividends or make distributions to its stockholders is
also restricted by the terms of the Credit Facility. See "Description of Certain
Indebtedness -- Credit Facility."

Analysis of Financial Condition and Results of Operations" included elsewhere in
this Prospectus. The selected unaudited pro forma statement of operations data

eight Seal Fleet Vessels in August 1996, the acquisition of eight crew boats
from GBMS in January 1996, the acquisition of one vessel in February 1996, the
IPO, and the repayment of certain indebtedness, as if all such transactions had
occurred on January 1, 1995. Such pro forma data are presented for illustrative
purposes only and do not purport to represent what the Company's results
actually would have been if such events had occurred at the dates indicated, nor
do such data purport to project results of operations for any future period or
as of any future date. The selected unaudited pro forma statements of operations
for the year ended December 31, 1995 and the nine months ended September 30,
1996 do not give effect to the Current Acquisitions or the Offering. The
selected balance sheet data at September 30, 1996 have been adjusted to give

vessel day rates or charter rates, and fleet utilization. Rates and utilization
are primarily a function of offshore drilling, production, and construction
activities. Levels of offshore drilling, production, and construction have
increased over the past several years as a result of fundamental changes in the
U.S. Gulf of Mexico energy industry, including: (i) improvements in exploration
technologies, such as computer-aided exploration and 3-D seismic, that have
increased drilling success rates in the region; (ii) improvements in subsea
completion and production technologies that have led to increased deepwater
drilling and development; and (iii) expansion of the region's production
infrastructure that has improved the economics of developing smaller oil and gas
fields. In addition, the short reserve life characteristics of U.S. Gulf of
Mexico gas production require continuous drilling to replace reserves and
maintain production. These higher overall activity levels have led to increased
demand for the Company's offshore energy support services and higher overall
vessel day rates and utilization in the U.S. Gulf of Mexico. Contracts for the
utilization of offshore service vessels commonly include termination provisions
with three- to five-day notice requirements and no termination penalty. As a
result, the operations of companies engaged in the offshore energy service
market are particularly sensitive to changes in market demand. See "Business --
The Industry -- Marine Support Services -- Offshore Energy Support."
 
     The following table sets forth average day rates achieved by the offshore
supply boats and crew boats owned or operated by the Company in the U.S. Gulf of
Mexico and their average utilization for the periods indicated.

     During the past five years, day rates and utilization in the U.S. Gulf of
Mexico were at their lowest during the summer of 1992 when the Company estimates
average offshore supply boat day rates were $1,300 to $1,400. As a result, in
the summer of 1992, a number of operators relocated supply boats from the U.S.
Gulf of Mexico to West Africa, the Arabian Gulf, and Southeast Asia. The Company
relocated five supply boats to the Arabian Gulf (all of which have been returned
to the U.S. Gulf of Mexico) and two to Southeast Asia in September 1992. Day
rates and utilization in the U.S. Gulf of Mexico increased through the end of
1993 primarily as a result of (i) Hurricane Andrew in the fall of 1992, which
caused substantial damage to pipeline and production facilities and greater
demand for supply boats, (ii) higher natural gas prices and increased drilling
activity for natural gas, and (iii) the reduced supply of immediately available
vessels. Management believes that relocation of vessels to the U.S. Gulf of
Mexico in early 1994 helped to depress day rates and utilization until the end
of the second quarter of 1994 and that industry day rates and utilization were
lower in the first half of 1995 because of weak natural gas prices, primarily
due to the warm winter in North America and Europe.
 
     Management believes that the increased activity in the U.S. Gulf of Mexico
since the second quarter of 1995 has been primarily attributable to improved
technology in the seismic industry and an approximate balance in the supply of
and demand for offshore service vessels. Deepwater activity is also currently a
positive factor in the market, and management believes further deepwater
exploration and production will likely increase demand for available vessels,
resulting in higher day rates and utilization.
 
     Offshore and Harbor Towing. Revenue derived from the Company's tug
operations is primarily a function of the number of tugs available to provide
services, the rates charged for their services, and the volume of vessel traffic
requiring docking and other ship-assist services. Vessel traffic, in turn, is
largely a function of the general trade activity in the region served by the
port. The Company generally has maintained four to five tugs in Port Everglades,
and three each in Port Canaveral and Mobile, although it has shifted tugs among
ports depending upon demand. Since the August 1995 delivery of the tractor tug
Broward, the Company has operated up to five tugs in Port Everglades with one of
the tugs available to provide offshore towing services.
 
     The following table summarizes certain operating information for the
Company's tugs.

  MARINE TRANSPORTATION SERVICES
 
     Chemical Transportation. Generally, demand for industrial chemical
transportation services coincides with overall economic activity. Since 1989,
revenue derived from chemical transportation operations has been entirely
attributable to the operations of Ocean Specialty Tankers Corporation ("OSTC"),
a company owned equally by OMI Corp. ("OMI") and the Company until August 1996,
when the Company acquired OMI's interest in OSTC along with the three OMI
Chemical Carriers. Prior to the acquisition, the Company's chemical
transportation revenue consisted of distributions from OSTC attributable to the
Company's two chemical carriers marketed by OSTC based upon a formula that took
into account individual vessel performance characteristics applied to OSTC's
revenue (net of fuel costs, port charges, and overhead). Since the acquisition,
the Company continues to have OSTC market the five chemical carriers and
receives the revenue attributable to all five of the vessels. See
"Business -- Company Operations -- Marine Transportation Services -- Chemical
Transportation -- OSTC."
 
     Petroleum Product Transportation. Since entering service in 1975, the
product carrier Seabulk Challenger has derived all of its revenue from
successive voyage and time charters to Shell. Under the current
 
                                       22
<PAGE>   24
 
charter, fuel and port costs are for the account of the charterer, charter hire
escalates based upon changes in the consumer price index, and charter hire is
suspended while the vessel is unavailable to transport cargo, as when it is
undergoing repairs or regularly scheduled maintenance. The charter extends to
January 2000, with the charterer retaining the right to early termination upon
the payment to the Company of a significant penalty. In the fourth quarter of
1996, the charter rate was renegotiated and reduced by approximately 6% to
reflect the lower current market rate. Revenue from the Company's towboats and
fuel barges has been derived primarily from contracts of affreightment with
Florida Power & Light Company ("FPL") and Steuart Petroleum Co. that require the
Company to transport fuel as needed by those two customers, with the FPL
contract having a guaranteed minimum utilization.
 
     The following table sets forth the average time charter equivalents for the
Company's chemical and product carriers, including the OMI Chemical Carriers as
if such vessels were owned by the Company during the periods presented.

OVERVIEW OF OPERATING EXPENSES AND CAPITAL EXPENDITURES
 
     The Company's operating expenses are primarily a function of fleet size and
utilization. The most significant expense categories are crew payroll and
benefits, depreciation and amortization, charter hire, maintenance and repairs,
fuel, and insurance.
 
     The crews of Company-manned chemical and product carriers are paid on a
time-for-time basis by which they receive paid leave in proportion to time
served aboard a vessel. The crews of offshore energy support vessels and certain
tugs and towboats are paid only for days worked.
 
     Charter hire consists primarily of payments made with respect to the
bareboat charters of the Seabulk Challenger and Seabulk Magnachem, which were
acquired pursuant to leveraged lease transactions (see "Description of Certain
Indebtedness -- Long-Term Charter Obligations -- Title XI Bonds") and operating
lease payments on the tractor tug Broward. In addition, the Company recently
entered into one-year charters of two newly built tugs. The Company also pays
charter hire when it charters harbor tugs to meet requirements in excess of its
own tugs' availability.
 
     The Company capitalizes expenditures exceeding $5,000 for product and
chemical tankers and $3,000 for all other vessels, where the item acquired has a
useful life of three years or greater. Vessel improvements and vessel
maintenance and repair are capitalized only if they also extend the useful life
of the vessel or increase its value. The Company overhauls main engines and key
auxiliary equipment in accordance with a continuous planned maintenance program.
Under applicable regulations, the Company's chemical and product carriers,
offshore service vessels, and its four largest tugs are required to be drydocked
twice in a five-year period for inspection and routine maintenance and repairs.
These vessels are also required to undergo special surveys every five years
involving comprehensive inspection and corrective measures to insure their
structural integrity and proper functioning of their cargo and ballast piping
systems, critical machinery and equipment, and coatings. The Company's fuel
barges, because they are operated in fresh water, are required to be drydocked
only twice in each ten-year period. The Company's harbor tugs and towboats
generally are not required to be drydocked on a specific schedule. During the
years ended December 31, 1993, 1994, and 1995 and the nine months ended
September 30, 1996, the Company drydocked five, 13, 42, and 17 vessels,
respectively, at an aggregate cost (exclusive of lost revenue) of $0.9 million,
$1.6 million, $2.0 million, and $0.6 million respectively. See "-- Liquidity and
Capital Resources" for information regarding anticipated maintenance and
improvement expense, including drydocking expense. Effective January 1, 1993,
the Company changed its method of accounting for drydocking costs from the
accrual method to the deferral method. Under the deferral method, capitalized
drydocking costs are expensed over the period preceding the next scheduled
drydocking. The Company believes the deferral method better matches costs with
revenue and minimizes any
 
                                       23
<PAGE>   25
 
significant changes in estimates associated with the accrual method. See Note 1
of the Company's consolidated financial statements. In addition to variable
expenses associated with vessel operations, the Company incurs fixed charges to
depreciate its marine assets. The Company calculates depreciation based on a
useful life ranging from 25 years for its steel-hull offshore energy support
vessels to 30 years for aluminum-hull vessels, the lesser of any applicable
lease term life or the OPA 90 life for its product and chemical carriers, ten
years for its fuel barges, and 40 years for its towboats and tugs.
 
     Insurance costs consist primarily of premiums paid for (i) protection and
indemnity insurance for the Company's marine liability risks, which are insured
by a mutual insurance association of which the Company is a member and through
the commercial insurance markets; (ii) hull and machinery insurance and other
maritime-related insurance, which are provided through the commercial marine
insurance markets; and (iii) general liability and other traditional insurance,
which is provided through the commercial insurance markets. Insurance costs,
particularly costs of marine insurance, are directly related to overall
insurance market conditions and industry and individual loss records, which vary
from year to year.
 
RESULTS OF OPERATIONS
 
  NINE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED WITH THE NINE MONTHS ENDED
SEPTEMBER 30, 1995
 
     Revenue. Revenue increased 41% to $72.1 million for the nine months ended
September 30, 1996 from $51.2 million for the nine months ended September 30,
1995 primarily due to increased revenue in the Company's offshore energy
support, petroleum product transportation, and chemical transportation
operations.
 
   
     Revenue from offshore energy operations increased 72% to $28.2 million for
the nine months ended September 30, 1996 from $16.4 million for the nine months
ended September 30, 1995 primarily due to acquisitions and greater utilization
of supply and crew boats and higher day rates resulting from increased offshore
exploration and production activity. During the 1996 period, day rates for
supply boats owned, operated, or managed by the Company increased 42% from the
1995 period, and day rates for crew boats owned, operated, or managed by the
Company increased 4% from the 1995 period. Utilization of supply boats increased
to 96% for the 1996 period from 77% for the 1995 period, and utilization of crew
boats increased to 93% for the 1996 period from 83% for the 1995 period.
    
 
     Petroleum product transportation revenue increased 22% to $14.4 million for
the nine months ended September 30, 1996 from $11.8 million for the nine months
ended September 30, 1995 primarily due to increased movements of product by the
Company's towboat and barge fleet as a result of the cold winter and higher
natural gas prices.
 
     Chemical transportation revenue increased 40% to $19.2 million for the nine
months ended September 30, 1996 from $13.7 million for the nine months ended
September 30, 1995 primarily due to the August 1996 acquisition of the OMI
Chemical Carriers and the remaining 50% interest in OSTC.
 
     Revenue from offshore and harbor tug operations increased 11% to $10.2
million for the nine months ended September 30, 1996 from $9.2 million for the
nine months ended September 30, 1995 primarily as a result of increased tanker
and freighter traffic in Port Everglades. Revenue also increased in the port of
Mobile due to a tariff increase and an increase in port traffic.
 
     Operating Expenses. Operating expenses increased 43% to $42.1 million for
the nine months ended September 30, 1996 from $29.5 million for the nine months
ended September 30, 1995 primarily due to increases in crew payroll and
benefits, maintenance and repair, and supplies and consumables resulting from
acquisitions and increased business activity. As a percentage of revenue,
operating expenses remained stable at 58% for both the nine months ended
September 30, 1996 and for the nine months ended September 30, 1995.
 
     Overhead Expenses. Overhead expenses increased 21% to $11.0 million for the
nine months ended September 30, 1996 from $9.2 million for the nine months ended
September 30, 1995 primarily due to an increase in professional fees relating to
pending litigation. Additionally, salaries and benefits increased as a result of
an increase in staffing requirements due to acquisitions. As a percentage of
revenue, overhead
 
                                       24
<PAGE>   26
 
expenses decreased to 15% for the nine months ended September 30, 1996 from 18%
for the nine months ended September 30, 1995.
 
     Depreciation and Amortization Expense. Depreciation and amortization
expense increased 30% to $6.1 million for the nine months ended September 30,
1996 compared with $4.7 million for the nine months ended September 30, 1995 as
a result of an increase in fleet size due to acquisitions.
 
     Income from Operations. Income from operations increased 64% to $12.9
million, or 18% of revenue, for the nine months ended September 30, 1996 from
$7.9 million, or 15% of revenue, for the nine months ended September 30, 1995 as
a result of the factors noted above.
 
     Net Interest Expense. Net interest expense increased 3% to $8.8 million for
the nine months ended September 30, 1996 from $8.5 million for the nine months
ended September 30, 1995 primarily as a result of debt incurred in connection
with acquisitions. As a percentage of revenue, net interest expense decreased to
12% for the nine months ended September 30, 1996 from 17% for the nine months
ended September 30, 1995.
 
     Net Income (Loss). The Company had a net loss of $5.3 million for the nine
months ended September 30, 1996 after incurring a net loss of $0.6 million for
the nine months ended September 30, 1995 primarily as a result of non-recurring
charges of $8.0 million, net of a $1.4 million income tax benefit, related to an
early extinguishment of debt in connection with the IPO.
 
  YEAR ENDED DECEMBER 31, 1995 COMPARED WITH YEAR ENDED DECEMBER 31, 1994
 
     Revenue. Revenue increased 42% to $70.6 million in 1995 compared with $49.8
million in 1994 primarily due to the Company's purchase of new businesses and
additional vessels.
 
     Offshore energy operations showed a 105% increase in revenue in 1995
primarily due to the acquisition of additional supply and crew boats. Although
revenue increased, the utilization of supply boats decreased to 81% in 1995 from
84% in 1994 and the utilization of crew boats decreased to 85% in 1995 from 88%
in 1994 due primarily to the relatively warm winter in early 1995, which caused
a decline in oil and gas prices thereby reducing exploration and production
activities. There was a 5% decrease in average day rates for the Company's
supply boats in 1995 from 1994, while average day rates for the Company's crew
boats remained relatively stable.
 
     Chemical transportation revenue increased 10% in 1995 primarily due to
fewer off-hire (out-of-service) days incurred by the Seabulk Magnachem in 1995
following its regularly scheduled drydocking in 1994.
 
     Revenue from petroleum product transportation increased 54% in 1995
primarily due to a full year of operating results for the Sun State tug and
barge fleet, which was acquired in September 1994.
 
     Revenue from offshore and harbor tug operations increased 13% to $12.6
million in 1995 from $11.1 million in 1994 primarily due to an increase in
overall traffic in the ports served by the Company.
 
     Operating Expenses. Operating expenses increased 36% to $40.7 million in
1995 from $29.9 million in 1994 primarily due to increased operating expenses
associated with acquisitions, although operating expenses decreased as a
percentage of revenues to 58% in 1995 from 60% in 1994.
 
     Overhead Expenses. Overhead expenses increased 31% to $12.5 million in 1995
compared with $9.6 million in 1994 primarily due to increases in staffing,
certain benefits, and insurance expenses directly related to new business
acquisitions. Also, in addition to paying discretionary performance bonuses in
April 1995 which were, in part, related to prior periods, an accrual of $400,000
was made at year end for 1995 performance bonuses. As a percentage of revenues,
overhead expenses decreased to 18% in 1995 from 19% in 1994.
 
     Depreciation and Amortization. Depreciation and amortization expense
increased 40% to $6.3 million in 1995 compared with $4.5 million in 1994
primarily due to an increase in fleet size as a result of acquisitions.
 
     Income from Operations. Income from operations increased 90% to $11.1
million, or 16% of revenue, in 1995 compared with $5.8 million, or 12% of
revenue, in 1994. This increase was a result of a substantial
 
                                       25
<PAGE>   27
 
increase in income from operations from the Company's offshore energy segment
and an increase in the Company's fuel energy segment that were mainly the result
of acquisitions. Harbor towing achieved an increase in income from operations of
25% over 1994 as a result of an overall increase in traffic in Mobile, Port
Canaveral, and Port Everglades.
 
     Net Interest Expense. Net interest expense increased 116% to $11.5 million,
or 16% of revenue, in 1995 compared with $5.3 million, or 11% of revenue, in
1994 primarily due to interest on debt incurred in the last quarter of 1994 to
finance acquisitions.
 
     Net Income (Loss). The Company had a net loss of $0.4 million in 1995
compared with net income of $0.4 million in 1994, primarily due to an increase
in financing costs incurred in connection with acquisitions completed in 1994
and the other factors noted above.
 
  YEAR ENDED DECEMBER 31, 1994 COMPARED WITH YEAR ENDED DECEMBER 31, 1993
 
     Revenue. Revenue increased 20% to $49.8 million for the year ended December
31, 1994 compared with $41.5 million for the year ended December 31, 1993
primarily due to the addition of revenue from acquisitions completed in 1994.
Revenue from offshore energy support services increased 150% primarily due to
revenue from such acquisitions. In addition, the Company's average Gulf of
Mexico supply boat day rates increased 19% in 1994 from an average of $2,696 per
day in 1993 to $3,195 per day in 1994, although supply boat fleet utilization
decreased from 98% to 84% due to the drydocking of two boats and the addition of
two boats with relatively low utilization rates in 1994. Revenue from chemical
transportation decreased 3% due to the Seabulk Magnachem having greater off-hire
time due to a regularly scheduled drydocking in April 1994. Revenue from
petroleum product transportation increased 15% primarily due to the Sun State
acquisition in September 1994. Offshore and harbor tug towing revenues increased
5% due to a general increase in vessel traffic in the ports served by the
Company.
 
     Operating Expenses. Operating expenses increased 24% to $29.9 million, or
60% of revenue, for the year ended December 31, 1994 compared with $24.0
million, or 58% of revenue, for the year ended December 31, 1993 primarily due
to the increased operating expenses associated with the acquisitions completed
in 1994. Charter hire expense increased due to the Company's chartering in May
and June of 1994 of certain supply and crew boats that were acquired in
September 1994, partly offset by a decrease in charter hire expense due to the
acquisition in September 1994 of the interests in the limited partnership that
owned the tug Hollywood (formerly the Cape Canaveral), which was previously
chartered to the Company.
 
     Overhead Expenses. Overhead expenses increased 55% to $9.6 million, or 19%
of revenue, for the year ended December 31, 1994 compared with $6.2 million, or
15% of revenue, for the year ended December 31, 1993 primarily due to increased
corporate staffing and other greater infrastructure costs associated with the
acquisitions completed in 1994, greater litigation expenses relating to the
Seabulk America (see "Business -- Legal Proceedings"), and expenses incurred to
prepare an initial public offering which was postponed due to market conditions.
Bonuses of approximately $280,000 were paid to Company management personnel in
October 1994 (no bonuses to management personnel were paid in 1993).
 
     Depreciation and Amortization. Depreciation and amortization expense
decreased 5% to $4.5 million for the year ended December 31, 1994 compared with
$4.7 million for the year ended December 31, 1993 primarily due to the
amortization of expenses incurred in 1993 to transport four offshore supply
boats from the Gulf of Mexico to the Arabian Gulf.
 
     Income from Operations. Income from operations decreased 11% to $5.8
million, or 12% of revenue, for the year ended December 31, 1994 compared with
$6.6 million, or 16% of revenue, for the year ended December 31, 1993 primarily
as a result of the factors described above.
 
     Net Interest Expense. Net interest expense increased 55% to $5.3 million,
or 11% of revenue, for the year ended December 31, 1994 compared with $3.4
million, or 8% of revenue, for the year ended December 31, 1993 primarily due to
interest due on the debt incurred to finance the acquisitions completed in 1994.
 
                                       26
<PAGE>   28
 
     Net Income. Net income decreased to $0.4 million for the year ended
December 31, 1994 compared with $3.3 million for the year ended December 31,
1993 primarily due to the factors described above and an approximate $1.5
million gain in 1993 resulting from a change in the Company's method of
accounting for drydocking.
 
SEASONALITY
 
     The Company has experienced some slight seasonality in its overall
operations. The first half of the year is generally not as strong as the second
half due to lower activity in offshore energy support activity and petroleum
product transportation during the months of February, March, and April.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's capital requirements historically have arisen primarily from
its working capital needs, acquisition of marine vessels, improvements to
vessels, and debt service requirements. The Company's principal sources of cash
have been borrowings, cash provided by operating activities, and proceeds from
the IPO in August 1996.
 
   
     In September 1994, the Company entered into the Credit Facility which, as
amended, currently provides for a $60.5 million term loan, a $10.0 million
revolving line of credit, a $19.9 million vessel acquisition credit line which
decreases to $11.5 million over a four-year period, and a $5.6 million letter of
credit. Borrowings under the Credit Facility bear interest at prime or LIBOR, at
the Company's option, plus a margin based on the Company's compliance with
certain financial ratios. At September 30, 1996, borrowings outstanding under
the Credit Facility aggregated $70.2 million, consisting of $60.5 million under
the term loan, $5.5 million under the revolving line of credit, and $4.2 million
under the vessel acquisition credit line. The Company has entered into a
commitment letter with its banks providing for an amendment to the Credit
Facility that would increase the amounts available under the revolving line of
credit and the acquisition credit line and make other modifications to the
Credit Facility. Upon entering into this amended Credit Facility, the Company
will write off approximately $1.2 million of deferred financing costs net of
applicable income taxes. See "Description of Certain Indebtedness -- Credit
Facility." The Company intends to repay all outstanding borrowings under the
revolving line of credit with proceeds of the Offering.
    
 
     Also in September 1994, the Company received $50.0 million in proceeds from
the issuance of the Senior Notes, the Junior Notes, and certain equity
securities. These proceeds, together with borrowings under the Credit Facility,
were utilized primarily to repay other indebtedness and to fund vessel
acquisitions.
 
     In August 1996, the Company completed the IPO, which resulted in net
proceeds to the Company of approximately $76.7 million. Of such net proceeds,
approximately $34.7 million was used to fund the $35.5 million cash portion of
the $97.5 million aggregate purchase price of the August 1996 Acquisitions and
approximately $42.0 million was used to repay certain indebtedness. The balance
of the purchase price of the August 1996 Acquisitions was paid by the assumption
or incurrence of $62.0 million of debt obligations. In addition, the Company
agreed to indemnify certain affiliates of one of the sellers for certain
liabilities up to a maximum of $7.0 million. Indebtedness repaid with proceeds
from the IPO included $7.0 million under the Credit Facility, $15.8 million of
accrued interest and principal under the Senior Notes, $15.1 million of accrued
interest and principal under the Junior Notes, and $4.1 million under certain
notes payable to affiliates of the Company. The $13.9 million balance of the
outstanding principal under the Junior Notes was converted into Class A Common
Stock and Class B Common Stock in September 1996. As of September 30, 1996,
$10.2 million of accrued interest and principal under the Senior Notes was
outstanding. All outstanding borrowings under the Senior Notes will be repaid
using a portion of the proceeds of the Offering.
 
     The Company's future capital needs are expected to relate primarily to debt
service obligations, maintenance and improvement of its fleet, and acquisitions.
The Company's outstanding indebtedness at September 30, 1996 was approximately
$134.3 million. Debt service requirements for the fourth quarter of 1996 were
approximately $4.0 million for principal and $2.7 million for interest, and
operating lease payments for the fourth quarter of 1996 were approximately $0.2
million. After giving effect to repayments under the revolving line of credit
under the Credit Facility, the Senior Notes, the Founder's Note and the HCL
Notes and HOS Notes with a portion of the proceeds of the Offering, the
Company's principal and interest payment
 
                                       27
<PAGE>   29
 
obligations for 1997 are estimated to be approximately $15.1 and $8.6 million,
respectively, and operating lease obligations for 1997 are estimated to be
approximately $3.9 million.
 
     Capital requirements for maintenance and improvement (excluding
improvements of $6.9 million associated with the Current Acquisitions) were
approximately $12.0 million for 1996, of which $9.1 million had been recorded as
either capital expenditures or construction in progress as of September 30,
1996, and are estimated to be approximately $15.0 million for 1997.
 
     The Company is considering contracting for the construction of two
ship-docking modules ("SDMs") at an estimated aggregate cost of approximately
$9.5 million with delivery expected in late 1997 or early 1998. The Company is
also considering the construction of five double-hull barges at an estimated
aggregate cost of approximately $9.0 million. The decision to proceed with the
construction of these barges will be based upon successful completion of
negotiations of long-term contracts with a customer concerning use of these
vessels. These negotiations are in a preliminary stage and there can be no
assurance that the construction of these barges will be undertaken. The Company
has also agreed to purchase for an estimated aggregate cost of $7.4 million
three newly constructed 152-foot crew boats scheduled for delivery in January,
May, and September 1998. Prior to delivery of the first of these crew boats in
January 1998, the Company's aggregate expenditures in connection with such
acquisitions are expected to be $190,000. The Company currently intends to fund
the aggregate cost of these SDMs, these crew boats, and, if built, these barges
from available working capital, borrowings under the Credit Facility, lease
financing, or a combination of such sources.
 
     An integral part of the Company's strategy is to acquire additional
vessels, thereby further consolidating its niche markets. The Company regularly
engages in discussions regarding potential acquisitions. However, other than the
Current Acquisitions, and as described in the immediately preceding paragraph,
no acquisitions have been agreed upon or are the subject of a letter of intent.
 
     The Company has a 2.4% equity interest in five 45,300 dwt double-hull
petroleum product carriers currently under construction. The aggregate cost of
the five carriers is estimated to be $255.0 million, of which approximately
$40.0 million will constitute equity investment and $215.0 million will be
financed with the proceeds of government-guaranteed Title XI ship financing
bonds issued in March 1996. Subject to certain conditions, the Company has an
option, exercisable through 2002, to purchase a 49.2% interest at a price equal
to (i) the investor's equity investment plus a stated annual return, or (ii) if
exercised after December 31, 1997, the greater of the fair market value of the
interest or the amount set forth in (i). The Company also has an option,
exercisable on January 15, 1998, to purchase an additional 23.4% interest at a
price equal to the investor's equity investment plus a stated return. Should the
Company fail to exercise the latter option, the investor has the option to
acquire 1.6% of the ownership interest from the Company for nominal
consideration. The total estimated cost of exercising the Company's options is
up to $32.0 million (assuming the options are exercised prior to January 1,
1998). The Company currently has no understandings or agreements with respect to
the financing that it would require if it were to exercise either or both of
these options, and there can be no assurance that such financing will be
available. See "Business -- Marine Transportation Services -- Petroleum Product
Transportation -- New Product Carriers."
 
     The Credit Facility currently restricts the Company's subsidiaries from
paying dividends or making other distributions to the Company. The Company does
not believe that this restriction has had or will have a material effect upon
its ability to meet its cash obligations because a substantial portion of those
obligations is payable by its subsidiaries. See "Description of Certain
Indebtedness -- Credit Facility."
 
     The Company is the defendant in litigation in which one of the shipyards
that completed the Seabulk America is seeking additional payments aggregating
$8.5 million for its work and $10.0 million of punitive damages, plus legal fees
and expenses. Although the Company believes the shipyard's claims are without
merit and has asserted counterclaims aggregating $5.6 million, the Company has
obtained a bank letter of credit to finance up to $5.6 million of any additional
payment that it might ultimately be required to make pursuant to this
litigation.
 
   
     Of the estimated $91.4 million net proceeds from the Offering, $35.6
million will be used in connection with the Current Acquisitions, $36.3 million
will be used to repay indebtedness, and the balance of
    
 
                                       28
<PAGE>   30
 
   
approximately $19.5 million will be available for general corporate purposes.
See "Use of Proceeds" and "Business -- Current Acquisitions."
    
 
     At September 30, 1996, the Company had a working capital deficit of $0.1
million. The Company believes that proceeds of the Offering, cash generated from
operations, and amounts available under the Credit Facility will be sufficient
to fund debt service requirements, planned capital expenditures, and working
capital requirements for the foreseeable future. The Company also believes that
such resources, together with the potential future use of debt or equity
financing, will allow the Company to pursue its strategy of growth through
acquisitions. However, since future cash flows are subject to a number of
uncertainties, including the condition of the markets served by the Company,
there can be no assurance that these resources will continue to be sufficient to
fund the Company's cash requirements.
 
EFFECT OF INFLATION
 
     The Company does not consider inflation a significant business risk in the
current and foreseeable future although the Company has experienced some cost
increases. In some cases, these increases have been offset by charter hire
escalation clauses.
 
NEW ACCOUNTING STANDARDS
 
     In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of," which requires impairment losses to be recorded on long-lived assets used
in operations when indicators of impairment are present and the undiscounted
cash flows estimated to be generated by those assets are less than the assets'
carrying amount. SFAS No. 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company adopted SFAS No. 121 in
the first quarter of 1996 and the effect of adoption was not material.
 
     In October 1995, the FASB issued Statement No. 123, "Accounting for
Stock-Based Compensation," for fiscal years beginning after December 15, 1995.
This statement establishes a fair-value based method of accounting for stock
compensation plans with employees and others. The Company continues to account
for its stock-based compensation plans under Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees," as permitted by SFAS No. 123
and will present the pro forma disclosures required under SFAS No. 123 in fiscal
year 1997 with no impact to the Company's results of operations.

                                    BUSINESS
 
GENERAL
 
     The Company provides marine support and transportation services primarily
in the U.S. domestic trade and principally to the energy and chemical
industries. The Company is the third largest operator of supply and crew boats
in the U.S. Gulf of Mexico. In addition, the Company is the sole provider of
commercial tug services in Port Everglades and Port Canaveral, Florida, and a
leading provider of such services in Mobile, Alabama. The Company also
transports petroleum products and specialty chemicals in the U.S. domestic
trade, a market insulated from international competition under the Jones Act.
The total capacity of the Company's five chemical carriers represents
approximately 44% of the capacity of the independent domestic specialty chemical
carrier fleet, and four of the vessels are among the last independently owned
chemical carriers scheduled to be retired under OPA 90.
 
     The Company has grown rapidly through a series of acquisitions, increasing
its marine support fleet from 20 vessels in 1993 to 74 vessels currently and its
marine transportation fleet from three vessels in 1993 to 29 vessels currently.
Primarily as a result of these acquisitions, the Company's revenues increased
196% from $41.5 million in 1993 to $123.0 million in 1995, on a pro forma basis.
Over the same period, the Company's EBITDA increased 181% from $11.3 million to
$31.7 million and its income from operations increased 186% from $6.6 million to
$18.9 million, in each case on a pro forma basis. For the nine months ended
September 30, 1996, the Company reported revenue, EBITDA, and operating income
of $101.0 million, $27.1 million, and $16.0 million, respectively, in each case
on a pro forma basis. For other measures of the Company's operating results as
determined under generally accepted accounting principles and its pro forma
operating results, see "Selected Historical and Pro Forma Consolidated Financial
Data" and the Company's consolidated financial statements.
 
     The Company has been operating in the marine support services industry
since its founding in 1958 and has been engaged in the transportation of
petroleum products and chemicals for 21 and 19 years, respectively. The
Company's executive officers have an average of over 22 years of experience in
the marine transportation industry, including an average of over 14 years with
the Company. As a result, the Company believes that it has had favorable
experience with respect to employee turnover and employee injury claims. The
Company's employees are predominantly non-union. See "-- Employees."
 
STRATEGY
 
     The Company's strategy is to realize the benefits presented by the
integration of its recent and pending acquisitions with its existing operations
and to continue to grow through selected acquisitions that further consolidate
the marine support and transportation services markets in which the Company
operates. The Company believes it has significant opportunities to make further
accretive acquisitions in its core businesses. Critical elements of the
Company's strategy include continuing to (i) utilize its demonstrated expertise
in acquiring vessels, thereby further consolidating its niche markets, (ii)
emphasize U.S. domestic trade operations, (iii) develop and apply marine
technology to meet its customers' needs in an innovative and cost-effective
manner, (iv) maintain and pursue long-term customer relationships that limit the
risk associated with the investments required for new vessels and mitigate the
effects of industry cyclicality, and (v) enhance its record of quality service
and safety.
 
     Demonstrated Expertise in Acquiring and Consolidating in its Niche
Markets. Many domestic maritime transportation markets, including offshore
energy support and towing, are undergoing consolidation. Small, privately owned
companies face increasing difficulty competing for market share, obtaining
adequate insurance coverage at economically viable rates, and meeting
increasingly more stringent customer and regulatory safety and environmental
requirements. The Company believes it is well positioned to take advantage of
this consolidation trend. The Company's recent acquisitions have substantially
increased the size of its fleet, established it as one of the leading operators
in the U.S. Gulf offshore energy market, and given it a
 
                                       30
<PAGE>   32
 
reputation as a successful consolidator in its niche markets. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Historical Growth" and "-- Current Acquisitions."
 
     U.S. Domestic Market Emphasis. The Company intends to continue to
concentrate its operations in markets protected by the Jones Act against
competition from foreign-built, foreign-crewed vessels. As a result, most of the
Company's vessels are, and will continue to be, built and maintained to U.S.
standards and registered under the U.S. flag. The Company believes that domestic
energy and chemical transportation freight rates will increase within the next
three to five years and continue to rise thereafter, as the supply of vessels
eligible to carry petroleum and other hazardous substances diminishes as a
result of mandatory retirement imposed by OPA 90.
 
     Technological Leadership and Business Innovation. The Company believes it
has been a leader in developing and applying marine technology to meet its
customers' needs in a cost-effective manner. Principals of the Company designed,
engineered, and developed the CATUG(R) integrated tug/barge ("ITB"), in which a
catamaran-hull tug is married to the stern section of a dedicated barge to
achieve construction cost savings and operating efficiencies, such as lower
manning requirements. The Seabulk Challenger, the Company's petroleum product
carrier, was the first of 12 CATUG(R)s constructed in the world. The Company's
Seabulk America is an innovative combination of the stern portion of a wrecked
oil tanker with the forebody of the chemical barge portion of a former ITB. By
combining this stern and forebody, the Company obtained the most recently
constructed chemical carrier in the U.S. domestic trade at a cost substantially
lower than that of a newly constructed vessel. The Company demonstrated its
business innovation in the formation of what was, prior to completion of the
August 1996 Acquisitions, the only pool of chemical carriers in the U.S.
domestic trade and most recently in the formation of the entities that will own
five new double-hull petroleum product carriers currently under construction.
See "-- Company Operations -- Marine Transportation Services."
 
     Long-term Relationships. The Company currently maintains and continues to
pursue long-term customer relationships. Long-term contracts can both minimize
the risk associated with the substantial investments frequently required for new
vessels and mitigate the effects of any cyclical downturns in the industry. This
element of the strategy began with the Company's long-term charter of its
petroleum product carrier to Shell and continued with the acquisition of the
towboat and fuel barge fleet in September 1994, which has a long-term contract
with FPL.
 
     Quality Service and Safety. Over a span of 38 years, the Company believes
it has built a reputation for providing its customers with the highest quality
service and safety in terms of timeliness, dependability, and technical
expertise. The Company continuously seeks to improve the quality of its service
both by upgrading the capabilities of its vessels and by increasing the skill
levels of its employees. It believes, for example, that its chemical carriers
have experienced a particularly low level of cargo degradation claims relative
to its competitors; that its emphasis on preventive maintenance minimizes vessel
time out of service and repair expenses; and that its reputation provides an
advantage in retaining customer loyalty (particularly in times of excess
capacity) and in entering new markets.
 
     As part of its continuing effort to maintain high standards of quality and
safety, the Company has obtained certification under the voluntary quality
assurance, safety, and environmental standards established under ISO 9002 and a
document of compliance with the International Ship Management Code, which
becomes mandatory in July 1998. The Company's success in establishing high
levels of quality and safety are further reflected by its receipt of Shell's
offshore safety award for the last three years.
 
CURRENT ACQUISITIONS
 
   
     The Current Acquisitions involve the acquisition of seven supply boats,
five crew boats, one offshore anchor handling tug, and two harbor tugs. The
aggregate cost of the Current Acquisitions is approximately $51.2 million,
including the cost of upgrading, refurbishing, and lengthening two of the supply
boats. Of such aggregate purchase price, $15.6 million had been paid as of
January 27, 1997 and the balance of $35.6 million
    
 
                                       31
<PAGE>   33
 
will be funded with a portion of the proceeds from the Offering, either by
direct payment to the sellers or through repayment of borrowings made under the
Credit Facility for such purpose. Certain of the Current Acquisitions are
subject to conditions precedent and there can be no assurance that such
acquisitions will be completed.
 
   
     Supply Boats.  In October and November 1996, the Company acquired two
supply boats from one seller for an aggregate purchase price of $4.6 million.
These supply boats are currently being upgraded, refurbished, and lengthened at
an estimated cost of $6.9 million and are expected to be placed in service
during the second quarter of 1997. In January 1997, the Company acquired one
supply boat for $4.7 million. In addition, the Company has entered into
agreements to acquire four additional supply boats in transactions scheduled to
close in April 1997 (two boats) and no later than June 1997 (two boats). The
aggregate purchase price of these four additional supply boats is $21.8 million,
against which the Company has made a $2.2 million deposit. The following table
sets forth certain information with respect to the seven supply boats included
in the Current Acquisitions.

THE INDUSTRY
 
     All marine transportation between points in the United States, including
drilling rigs affixed to the U.S. outer continental shelf, is restricted by law
to vessels built and registered in the United States and owned and manned by
U.S. citizens. The U.S. domestic trade includes a number of market segments,
including the servicing of domestic offshore oil and gas drilling and production
platforms, the providing of offshore and harbor towing services to the offshore
energy industry, tankers and other vessels, and the transportation of fuels,
petroleum products, and chemicals along and between U.S. coasts. All of the
Company's vessels are eligible to participate in the U.S. domestic trade except
for two Panamanian-flag offshore supply boats operating in Southeast Asia
pursuant to contracts expiring in 1998.
 
  MARINE SUPPORT SERVICES
 
     Offshore Energy Support. Marine support vessels serving offshore energy
exploration and production operations are used primarily to transport materials,
supplies, equipment, and personnel to drilling rigs and to support the
construction, positioning, and ongoing operation of oil and gas production
platforms. Offshore energy support vessels are hired by oil companies and others
engaged in offshore exploration activities, generally on a short-term (less than
six months) basis at varying day rates. See "-- Customers and Charter Terms."
The types of vessels primarily utilized in these activities are supply boats,
crew boats, and anchor handling vessels.
 
     Supply boats (also called workboats) are generally at least 150 feet in
length and serve exploration and production facilities and support offshore
construction and maintenance activities. Supply boats are differentiated from
other vessel types by cargo flexibility and capacity. In addition to
transporting deck cargo, such as drill pipe and heavy equipment, supply boats
transport liquid mud, potable and drilling water, diesel fuel, dry bulk cement,
and dry bulk mud. With their relatively large liquid mud and dry bulk cement
capacity and large areas of open deck space, they are generally in greater
demand than other types of support vessels for exploration and workover drilling
activities.
 
     Crew boats (also called crew/supply boats) are faster and smaller than
supply boats and are utilized primarily to transport light cargo, including food
and supplies, and personnel to and among production platforms, rigs, and other
offshore installations. They can be chartered together with supply boats to
support drilling or construction operations or separately to serve the various
requirements of offshore production platforms. Crew boats are typically
constructed of aluminum and generally have longer useful lives than steel-hull
supply boats. Crew boats also provide a cost-effective alternative to helicopter
transportation services and can operate reliably in all but the most severe
weather conditions.
 
     Anchor handling vessels, which include anchor handling tug/supply vessels
and some tugs, are more powerful than supply boats and are capable of towing and
positioning drilling rigs, production facilities, and construction barges. Some
are specially equipped to assist tankers while they are loading from
single-point buoy mooring systems.
 
     There has been substantial worldwide vessel attrition over the past ten
years as many vessels have reached the end of their useful lives. The number of
offshore supply boats of at least 150 feet in length available for service in
the U.S. Gulf of Mexico decreased from a peak of approximately 700 in 1985 to
approximately 260 in August 1996. Management estimates that during the same
period, the number of companies operating supply boats of at least 150 feet in
length decreased from approximately 40 to 16. Day rates declined in the
mid-1980s and have since improved from an average of $1,730 in August 1987 to an
average of $5,683 in the third quarter of 1996. Although some supply boats were
redeployed from the U.S. Gulf of Mexico to overseas locations, management
believes that existing regulations, mobilization costs, and overseas
opportunities will limit the number of such vessels returning to the U.S. Gulf
of Mexico in the foreseeable future. Management believes that new construction
of offshore supply vessels likely will consist of larger, more capable vessels
of approximately 220 feet in length.
 
                                       33
<PAGE>   35
 
     The Company estimates that there are currently approximately 13 crew boat
operators in the U.S. Gulf of Mexico operating a total of 200 vessels of at
least 120 feet in length. There are approximately 42 crew boats greater than 120
feet in length currently under construction (not all of which are expected to be
utilized in the U.S. Gulf of Mexico), and the Company believes that current
demand created by exploration for oil in the deeper waters of the U.S. Gulf of
Mexico may support construction of a limited number of additional crew boats.
 
     The following table sets forth as of November 26, 1996, the Company's
estimate of the number of supply boats and crew boats operating in the U.S. Gulf
of Mexico giving effect, in the case of the Company, to the Current
Acquisitions.

    Current Acquisitions.
 
     While existing exploration and production activities create an ongoing
demand for offshore energy support vessels, incremental vessel demand depends
primarily upon the level of drilling activity, which in turn depends on oil and
gas prices. As a result, drilling rig day rates and utilization are influenced
by oil and gas prices, which are highly cyclical. The relationship since 1993
between natural gas prices and drilling rig utilization in the U.S. Gulf of
Mexico and, similarly, average vessel utilization, is displayed in the following
table.

    as they are not considered meaningful (i.e., tugs work on a per-job basis,
    not a daily basis).
 
     Offshore and Harbor Towing. Offshore and harbor towing services are
provided by tugs to vessels utilizing the ports in which the tugs operate and to
vessels at sea to the extent required by environmental regulations, casualty, or
other emergency. The Company's anchor handling tug/supply boats and offshore
towing-equipped tugs have been engaged in towing a wide variety of barges
carrying heavy equipment, refinery modules, and petroleum products for the
energy industry in the U.S. Gulf of Mexico, the Atlantic Ocean, and the
Mediterranean Sea. In the case of docking services, charges are based on a fixed
rate per job, and in the case of towing services, on hourly or daily rates. In
most ports, competition is unregulated, although a few port
authorities -- including Port Canaveral and Port Everglades, Florida where a
majority of the Company's tugs operate -- grant non-exclusive franchises to
harbor tug operators. Rates are unregulated in franchised ports served by the
Company. See "-- Customers and Charter Terms." Each port is generally a distinct
market for harbor tugs, even though harbor tugs can be moved from port to port.
Demand for towing services depends on vessel traffic, which is in turn generally
dependent on local and national economic conditions. OPA 90 and current state
legislation require oil tankers to be escorted in and around certain ports
located in Alaska and the U.S. Pacific coast. The Company anticipates that such
regulatory requirements will be expanded, increasing the demand for specially
designed tractor tugs, such as the Broward, to perform escort services.
 
  MARINE TRANSPORTATION SERVICES
 
     Chemical Transportation. In the domestic chemical transportation trade,
vessels carry chemicals primarily from chemical manufacturing plants and storage
tank facilities along the U.S. Gulf of Mexico coast to industrial users in and
around the Atlantic and Pacific coast ports and along inland rivers and
waterways. The chemicals primarily transported are caustic soda, alcohols,
chlorinated solvents, paraxyzlene, alkylates, toluene, methyl tertiary butyl
ether (MTBE), phosphoric acid, and lubricating oils. Since 1989, coastwise
chemical tonnage demand has increased as a result of the general expansion of
the U.S. economy and as gasoline additives have begun to move coastwise. Certain
of the chemicals transported must be carried in vessels with specially coated or
stainless steel cargo tanks. Many are very sensitive to contamination and
require special cargo-handling equipment.
 
     The Company estimates that approximately 11% (in terms of tonnage) of bulk
domestic chemical transportation is waterborne, with the remainder transported
by rail. The Company also estimates that approximately 60% of that waterborne
trade is in specialty chemicals, such as caustic soda, which can be transported
only by specially designed vessels. Although chemical carriers and petroleum
product carriers are similar in design, vessels engaged in the transportation of
petroleum products generally lack the large number of small tanks, special tank
coatings, and sophisticated cargo-handling capability necessary to operate in
the parcel or specialty chemical trade. Parcel shipments are usually carried
pursuant to contracts of affreightment
 
                                       35
<PAGE>   37
 
by which a shipper contracts for the use of a portion of a vessel's cargo
capacity. See "-- Customers and Charter Terms."
 
     Vessels engaged in domestic chemical transportation that are owned by major
chemical or other companies that use the vessels to transport cargoes for their
own accounts are referred to as "captive" or proprietary vessels. Management
believes that there are 13 specialty chemical carriers active in the domestic
trade, of which nine are non-proprietary, or independently operated, and four
are proprietary. Some of these vessels also transport petroleum products, and
all but one of them will be ineligible to do so after the year 2015 in
accordance with OPA 90 double-hull requirements. See "-- Environmental and Other
Regulation -- Clean Water Regulations." The Seabulk America is the only chemical
carrier to enter service in the domestic trade since 1984, and no new specialty
chemical carriers are currently under construction. In addition to the specialty
chemical tankers, there are 44 tankers and 90 barges in the U.S.-flag domestic
fleet over 10,000 gross tons that are capable of carrying some so-called "easy
chemicals," such as gasoline additives (e.g. MTBE), and that compete with
specialty chemical carriers for the transportation of those chemicals.
 
     The following table sets forth certain information concerning mandatory OPA
90 retirement dates (from transportation of petroleum products) for the 13
active specialty chemical carriers eligible to participate in the U.S. domestic
trade. The Company believes that certain of these vessels will be retired once
they are no longer able to augment their cargoes with petroleum products and
that some may be retired in advance of their OPA 90 retirement dates as required
capital investments may not be economically justifiable over the remaining lives
of the vessels. The retirement dates of others may be extended by reducing their
gross registered tonnage and cargo capacity.

     Although single-hull chemical carriers may be permitted to continue to
carry chemicals in the U.S. domestic and foreign trade after their OPA 90
retirement dates, the Company believes that the inability of single-hull
carriers to augment chemical cargoes with petroleum products (such as
lubricating oils) after such dates will, in light of the current near balance
between supply and demand and assuming increasing chemical shipment volume as a
result of improvements in the economy, result in increased charter rates for the
Company's chemical carriers.

     Petroleum Product Transportation. In the domestic energy transportation
trade, oceangoing and inland-waterway vessels transport fuel and other petroleum
products, primarily from the U.S. Gulf of Mexico coast refineries and storage
facilities, to utilities, waterfront industrial facilities, and distribution
facilities along the U.S. Gulf of Mexico, the Atlantic and Pacific coasts, and
inland rivers. The inventory of U.S.-flag oceangoing vessels eligible to
participate in the U.S. domestic trade and capable of transporting fuel or
petroleum products has steadily decreased since 1980 as vessels have reached the
end of their useful lives and the cost of constructing a vessel in the United
States (a requirement for U.S. domestic trade participation) has exceeded the
level at which it was economically feasible to order a new vessel.
 
     The following graph sets forth the projected number of U.S.-flag chemical
and product tankers from 20,000 dwt to 55,000 dwt remaining eligible to
transport crude oil and petroleum products in the U.S. domestic trade as of the
dates indicated:

(1) Assumes delivery of twelve vessels from 1997 through 2004, including
    delivery in 1998 of the five petroleum product carriers in which the Company
    has an interest, and scrap dates one year in advance of OPA 90 mandated
    retirement dates.
 
     As a result of the retirement dates for single-hull tankers mandated by OPA
90, the Company believes that, of the 71 U.S.-flag product and chemical carriers
and product and chemical barges from 20,000 dwt to 55,000 dwt currently
operating, 19 will have to be retired by the end of year 2000. See
"-- Environmental and Other Regulation -- Clean Water Regulations." Replacement
vessels currently under construction consist of three late 1950s-built
steam-powered single-hull product carriers being converted to double-hull
vessels for delivery in 1997 and the five new diesel-powered double-hull product
carriers in which the Company has an interest. See "-- Company
Operations -- Marine Transportation Services -- Petroleum Product
Transportation -- New Product Carriers." The Company believes that the mandatory
replacement of single-hull carriers by environmentally safer double-hull vessels
will result in a gradual increase in charter rates for product carriers over the
next few years.

     Offshore Energy Support. The Company has provided services to the oil and
gas drilling industry since 1989, when it acquired its first eight offshore
supply boats. In September 1994, March 1995, and January and February 1996, the
Company expanded its offshore energy support service fleet by acquiring an
aggregate of six supply boats and two utility boats (seven of which it was
previously operating or managing) and 36 crew boats. In August 1996, the Company
acquired ten supply boats and one crew boat.

     Offshore and Harbor Towing. The tugs currently owned or operated by the
Company serve Port Everglades and Port Canaveral, Florida and Mobile, Alabama,
where they primarily assist product carriers, barges, other cargo vessels, and
cruise ships in docking and undocking and in proceeding in confined waters. The
Company recently entered into one-year bareboat charters of two newly
constructed 4,000-hp tugs equipped with omni-directional propulsion units and
having some of the capabilities of tractor tugs. These tugs are serving as
harbor tugs in Mobile, enabling two of the Company's harbor tugs to be utilized
in offshore towing activities. As a result, the Company now operates three tugs
with offshore towing capabilities that conduct a variety of offshore towing
services in the U.S. Gulf and the Atlantic Ocean.
 
     Port Everglades. Port Everglades has the second largest petroleum
non-refining storage and distribution center in the United States, providing
substantially all of the petroleum products for South Florida. Since 1958, when
the Company's tug operations were established, the Company has enjoyed a
franchise as the sole provider of docking services in the port. That franchise
specifies, among other things, that three tugs serving the port be less than 90
feet in length, because of the narrowness of slips in the port, and that tugs
have firefighting capability. The franchise is not exclusive and another
operator could be granted an additional franchise. Although a significantly
larger potential competitor sought a franchise in 1992, the Company won
unanimous endorsement from the Port Authority to continue its sole-franchise
relationship with the port when that competitor failed to make the requisite
showing of public need and necessity. The current franchise expires in 2001, and
there can be no assurance that it will be renewed.
 
     In 1995, the Company took delivery of a new 5,100-hp tractor tug, the
Broward, which has been operating in Port Everglades. The Company operates the
Broward, built at a cost of $6.4 million by a third-party shipyard, pursuant to
a long-term operating lease. Company personnel, working in conjunction with
consulting marine engineers and architects, prepared the conceptual design,
including the tug's distinctive hull form, prepared detailed specifications, and
supervised the construction of the tug.
 
     Tractor tugs have forward-mounted, omni-directional propulsion units,
giving them a high degree of maneuverability and control over the operation of
an escorted oil tanker or other vessel, and are generally considered superior
for tanker escort service. The Broward has twin 2,550-hp diesel engines and twin
propeller nozzles capable of turning 360 degrees. Although all of the Company's
harbor tugs are equipped for firefighting and their crews trained to respond to
fires and oil-spill emergencies, the Broward has significantly enhanced
firefighting capabilities, with two large water cannons capable of producing
6,000 gallons per minute for spraying water or foam. Although a number of
tractor tugs are in operation around the world, there are no others in
commercial service in the southeastern United States. The Broward is also used
to provide tanker escort services and specialized offshore energy support
services.
 
     Port Canaveral. The Company expanded its services in the early 1960s to
Port Canaveral, Florida where, like Port Everglades, it also has the sole
franchise from the port authority to provide harbor docking services. Port
Canaveral is the smallest of the Company's harbor tug operations, providing
docking and undocking services for commercial cargo vessels serving central
Florida and for cruise ships visiting the Disney World/Kennedy Space Center
attractions. The Company's franchise is a month-to-month arrangement and,
although there can be no assurance that the Company will be able to retain its
franchise in Port Canaveral, there has been no challenge to the franchise since
1984.
 
     Mobile. In 1988, the Company purchased a division of a towing company
operating in the port of Mobile, Alabama. The port provides docking and
undocking services primarily for commercial cargo vessels, including vessels
transporting coal and other bulk exports. At the time, that division operated
three harbor tugs in Mobile. The Company added additional equipment and believes
it significantly upgraded the quality and performance of the tug service, thus
enabling the Company to increase its market share to approximately 50% of the
harbor tug business in that port since commencing operations.

(1) Equipped for offshore towing.
 
(2) Vessel included in Current Acquisitions. See "-- Current Acquisitions."
 
(3) Vessel operated under a one-year bareboat charter.
 
(4) Expected to be retired in the second quarter of 1997.
 
     Ship-Docking Modules. The Company is considering contracting for the
construction of two SDMs for delivery in late 1997 or early 1998. SDMs are
innovative ship-docking vessels that are designed to be more maneuverable,
efficient, and flexible than harbor tugs. In addition, they are expected to have
lower operating costs than harbor tugs because they require fewer crew members.
Company personnel, working in conjunction with consulting marine engineers and
architects, prepared the conceptual design and detailed specifications for the
SDMs. The Company has filed a patent application on the design. It is currently
anticipated that one SDM will operate in Port Everglades and one in Mobile and
that their deployment will make one or two of the bareboat chartered tugs
available for alternative service or redelivery to their owner.
 
  MARINE TRANSPORTATION SERVICES
 
     Chemical Transportation.
 
     The Company's chemical carriers are the 298,000-barrel, 39,300 dwt Seabulk
Magnachem, the 297,000-barrel, 46,300 dwt Seabulk America, the 360,000-barrel,
50,900 dwt HMI Dynachem, the 360,000-barrel, 50,900 dwt HMI Petrochem, and the
260,000-barrel, 37,100 dwt HMI Astrachem, which are primarily engaged in the
U.S. domestic chemical parcel trade. The Company operates the Seabulk Magnachem
pursuant to a long-term bareboat charter. See "Description of Certain
Indebtedness -- Long-Term Charter Obligations -- Title XI Bonds." The Company
owns a 67% economic interest, and Stolt Tankers (U.S.A.), Inc. owns the
remaining 33% economic interest, in the Seabulk America.
 
     The Seabulk Magnachem, the Seabulk America, the HMI Dynachem, and the HMI
Petrochem have full double bottoms (as distinct from double hulls) and the HMI
Astrachem has a partial double bottom. Double bottoms provide increased
protection over single hull vessels from a spill in the event of a mishap. The
Company's chemical carriers have from 13 to 24 cargo segregations which are
configured, strengthened, and coated to handle various sized parcels of a wide
variety of industrial chemical and petroleum products giving them the ability to
handle a broader range of chemicals than chemical-capable product carriers. Many
of the
 
                                       41
<PAGE>   43
 
chemicals transported by the Company are hazardous substances. Voyages are
currently generally conducted from the Houston and Corpus Christi, Texas, and
Lake Charles, Louisiana areas to such ports as New York, Philadelphia,
Baltimore, Norfolk, Wilmington, North Carolina, and Charleston, South Carolina.
Delivered in 1977, the Seabulk Magnachem is a CATUG(R) ITB, which requires fewer
personnel to operate than a conventional carrier of equivalent size and has a
higher level of dependability, propulsion efficiency, and performance than an
ordinary tug and barge. Delivered in 1990, the Seabulk America is the only
vessel in the U.S. domestic trade capable of carrying large cargoes of acid, as
a result of its large high-grade alloy stainless steel tanks, and the only such
vessel strengthened to carry relatively heavy cargoes such as phosphoric and
other acids. The Seabulk America's stainless steel tanks were constructed
without internal structure, which greatly reduces cargo residue from
transportation and results in less cargo degradation. Stainless steel tanks,
unlike epoxy-coated tanks, also do not require periodic sandblasting and
recoating. The Seabulk America was one of the first U.S.-flag carriers to be
equipped with state-of-the-art integrated navigation, cargo control monitoring,
and automated engine room equipment.
 
     Pursuant to the requirements of OPA 90, the Seabulk America, the HMI
Dynachem, the HMI Petrochem, and the Seabulk Magnachem, which were built with
full double bottoms but not double sides, cannot be utilized to transport
petroleum and petroleum products in U.S. commerce after 2015, 2011, 2011, and
2007, respectively. The HMI Astrachem, which has a partial double bottom, cannot
be so utilized after 2000. See "-- Environmental and Other Regulation -- Clean
Water Regulations." They may, however, be permitted to continue to carry certain
chemicals in U.S. commerce and may be redocumented in another country and
transport chemicals in non-U.S. trades. Although it has no current plans to do
so, the ITB design of the Seabulk Magnachem would allow the Company to replace
only the cargo-carrying portion of the vessel with a double-hull barge, which
the Company anticipates would be substantially less expensive than constructing
an entirely new double-hull conventional tank vessel.
 
     The Company markets the five chemical carriers through its wholly owned
subsidiary OSTC. The total capacity of the five carriers represents
approximately 44% of the capacity of the domestic specialty chemical carrier
fleet, and four of the chemical carriers are among the last independently owned
carriers scheduled to be retired under OPA 90. See "-- The Industry -- Marine
Transportation Services -- Chemical Transportation."
 
     OSTC books cargoes either on a spot (movement-by-movement) or time basis.
Approximately 75% of contracts for cargo are committed on a 12- to 18-month
basis, with minimum and maximum cargo tonnages specified over the period at
fixed rates per ton. The HMI Dynachem and HMI Astrachem are currently chartered
to major oil companies under charters that expire in August 1997 and November
1997, respectively. Upon the expiration of these charters, the Company intends
to enter into new contracts of affreightment or time charters to market those
vessels. OSTC is often able to generate additional revenues by chartering cargo
space on competitors' vessels and by expanding the carriers' backhaul (return
voyage) opportunities.
 
     Petroleum Product Transportation.
 
     Seabulk Challenger. The 320,000-barrel, 39,300 dwt CATUG(R) ITB Seabulk
Challenger is engaged in the transportation of fuel and other petroleum products
from Shell's refineries in Texas and Louisiana to tank farms and industrial
sites primarily in Port Everglades, Tampa, and Jacksonville, Florida. Delivered
in 1975, the Seabulk Challenger has six cargo segregations and was the first
CATUG(R) ITB constructed in the world. Like the Seabulk Magnachem, it enjoys
certain manning and other advantages over conventional tank vessels. In 1989 and
1991, the vessel had extensive steel renewals and tank recoatings. In addition,
in 1991 the vessel was outfitted with an inert-gas system at the expense of the
charterer.
 
     The Seabulk Challenger has been under continuous contract to Shell since
its delivery in 1975 and to date has performed over 600 voyages for Shell. In
January 1990, Shell renewed the charter for a ten-year period ending in January
2000. Under the charter, the Company is responsible for operating costs such as
crew, maintenance, and insurance, and Shell pays for voyage costs such as fuel
and port charges. The charter hire rate is adjusted annually for inflation. The
charter may be canceled by Shell in January 1998 and January 1999 upon payment
of a percentage of the charter hire due over the remaining term of the charter.
Shell has in the
 
                                       42
<PAGE>   44
 
past repeatedly renewed its charter of the Seabulk Challenger, and continues to
fully utilize the vessel. Because the termination penalties are substantial, and
Shell has provided significant capital enhancement to the vessel, the Company
believes that Shell will continue to charter the vessel until January 2000,
although there can be no assurance that it will do so. In the fourth quarter of
1996, the charter rate was renegotiated and reduced by approximately 6% to
reflect the lower current market rate.
 
     The Seabulk Challenger, like the Company's chemical carriers and
single-hull barges, cannot be operated in U.S. waters after its January 2003
phase-out date under OPA 90. As with the Seabulk Magnachem, the Company could,
but has no current plans to, replace the barge portion of the Seabulk Challenger
with a double-hull barge, which the Company anticipates would be substantially
less expensive than constructing an entirely new double-hull conventional tank
vessel.
 
     Sun State. In September 1994, the Company acquired the marine assets of Sun
State Marine, Inc. ("Sun State"), which then owned and operated an energy
transportation fleet of ten towboats and eight fuel barges (one small barge was
acquired in April 1995 and four small barges were acquired in December 1995),
all of which are engaged in fuel transportation along the Atlantic intracoastal
waterway and in the St. Johns River in Florida. Sun State has been in operation
for over 50 years, and the Company continues to operate it as a wholly-owned
subsidiary.
 
     A majority of Sun State's revenue for the year ended December 31, 1995 and
the nine months ended September 30, 1996 was derived from a fuel transportation
contract with FPL. The remainder of its revenue was derived from a fuel
transportation contract with another customer and its marine maintenance,
repair, and drydocking facility. See "-- Other Services." Under its contract
with FPL, which has a term extending to September 1998, Sun State has agreed to
transport fuel oil from Port Canaveral and Jacksonville to certain FPL electric
power generating facilities at specified rates (a combination of per diem and
variable rates based upon barrels transported) with an escalation provision. The
FPL contract has a specified guaranteed minimum utilization provision.
 
     The Sun State towboats are as follows:

     OPA 90 requires all single-hull barges, including the Sun State barges, to
discontinue transporting fuel and other petroleum products in 2015.
 
     The Company is considering the construction of five double-hull barges at
an estimated aggregate cost of approximately $9.0 million. The decision to
proceed with the construction of these barges will be based upon successful
completion of negotiations of long-term contracts with a customer concerning use
of these vessels. These negotiations are in a preliminary stage and there can be
no assurance that the construction of these barges will be undertaken.
 
     New Product Carriers. The Company has a 2.4% equity interest in five 45,300
dwt double-hull petroleum product carriers currently under construction by
Newport News Shipbuilding and Drydock Co. for delivery during 1998. The
aggregate cost of the five carriers is estimated to be $255.0 million, of which
approximately $40.0 million will constitute equity investment and $215.0 million
will be financed with the proceeds of government-guaranteed Title XI ship
financing bonds issued in March 1996. In addition to the Company's interest, 25%
of the equity interest in the vessels is held by Van Ommeren International BV
and 49.3% and 23.4%, respectively, by two other investors. Subject to the
condition that the current owner of the 49.3% interest has not previously sold
such interest to a third party, the Company has an option, exercisable through
2002, to purchase the 49.3% interest at a price equal to (i) the investor's
equity investment plus a stated annual return, or (ii) if exercised after
December 31, 1997, the greater of the fair market value of the interest or the
amount set forth in (i). The Company also has an option, exercisable on January
15, 1998, to purchase the additional 23.4% interest at a price equal to the
investor's equity investment plus a stated return. Should the Company fail to
exercise the latter option, the investor has the option to acquire 1.6% of the
ownership interest from the Company for nominal consideration. The total
estimated cost of exercising the Company's options is up to $32.0 million
(assuming the options are exercised prior to January 1, 1998). The Company
currently has no understandings or agreements with respect to the financing that
it would require if it were to exercise either or both of these options, and
there can be no assurance that such financing will be available.
 
     The five double-hull product carriers, the operations of which will be
managed by the Company, are intended to serve the market currently served by
single-hull product carriers whose retirement is mandated by OPA 90. The vessels
will operate in the U.S. domestic trade and may be operated pursuant to long- or
short-term charters, depending upon market conditions during the period prior to
their delivery and thereafter. The Company is serving as the construction
supervisor during the construction period. The construction project is currently
the subject of litigation. See "-- Legal Proceedings."

  OTHER SERVICES
 
     As part of the Sun State acquisition, the Company also acquired a small
marine maintenance, repair, and drydocking facility in Green Cove Springs,
Florida, which is engaged principally in the maintenance of tugs and barges,
offshore support vessels, and other small vessels. The lease for the facility,
including options, expires in 2000. The towboat Sun River City was constructed
in the Green Cove Springs facility, which is capable of drydocking vessels up to
300 feet in length for repair and can make dockside repairs on vessels up to 320
feet in length. Since October 1994, the Green Cove Springs facility has been
utilized to overhaul or rebuild a number of the Company's harbor tugs and
offshore energy support vessels. The facility (originally a U.S. government
naval repair and operations station) has covered steel fabrication facilities,
workshops, and office spaces adjacent to a 1,840-foot finger pier and mooring
basins, where the facility's three floating drydocks are located. The drydocks
are 60, 80, and 108 feet in length, and are capable of lifting 350, 200, and 500
tons, respectively. The 60 and 108 foot drydocks are capable of being joined
together for lifting a vessel or barge with a nominal capacity of 1,175 long
tons.
 
  CUSTOMERS AND CHARTER TERMS
 
     The Company offers its offshore energy support services primarily to oil
companies and large drilling companies. Consistent with industry practice, the
Company's U.S. Gulf of Mexico operations are conducted primarily in the "term"
market pursuant to short-term (less than six months) charters at varying day
rates. Generally, such short-term charters can be terminated by either the
Company or its customer upon notice of five days or less.
 
     The Company offers its offshore and harbor towing services to vessel owners
and operators and their agents. The Company's rates for harbor towing services
are set forth in the Company's published tariffs and are subject to modification
by the Company at any time, limited by competitive factors. The Company also
grants volume discounts to major users of harbor services. Offshore towing
services are priced based upon the service required on an ad hoc basis.
 
     The primary purchasers of chemical transportation services are chemical and
oil companies. The primary purchasers of petroleum product transportation
services are utilities, oil companies, and large industrial consumers of fuel
with waterfront facilities. Both services are generally contracted for on the
basis of short- or long-term time charters, voyage charters, contracts of
affreightment, or other transportation agreements tailored to the shipper's
requirements. Shell is the Company's largest single customer and the long-term
charterer of the Seabulk Challenger. In addition, Chevron is a purchaser of the
Company's offshore energy support services and each of Phillips and Amoco
currently charters one of the Company's chemical carriers. Shell, Amoco,
Phillips and Chevron each accounted for between 5% and 10% of the Company's
revenue for the nine months ended September 30, 1996 on a pro forma basis, and
Shell and Phillips each accounted for between 5% and 10% of the Company's
revenue for the year ended December 31, 1995 on a pro forma basis. The loss of
any of these customers could have a material adverse effect on the Company.
 
COMPETITION
 
     The Company operates in a highly competitive environment in all its
operations. The principal competitive factors in each of the markets in which
the Company operates are suitability of equipment, personnel, price, service,
and reputation. The Company's vessels that provide chemical and petroleum
products transportation services compete with both other vessel operators and,
in some areas and markets, with alternative modes of transportation, such as
pipelines, rail tank cars, and tank trucks. Moreover, the users of such services
are placing increased emphasis on safety, the environment, and quality, partly
due to heightened liability for the cargo owner in addition to the vessel
owner/operator under OPA 90. See "-- Environmental and Other Regulation -- Clean
Water Regulations." With respect to towing services, the Company's vessels
compete not only with other providers of tug services, but with the providers of
tug services in nearby ports. Many of the companies with which the Company
competes have substantially greater financial and other resources than the
Company. Additional competitors may enter the Company's markets in the future.
Moreover, should U.S. coastwise laws be repealed, foreign-built, foreign-manned,
and foreign-
 
                                       45
<PAGE>   47
 
owned vessels could be eligible to compete with the Company's vessels. See
"-- Environmental and Other Regulation -- Coastwise Laws."
 
ENVIRONMENTAL AND OTHER REGULATION
 
     The Company's operations are subject to significant federal, state, and
local regulation, the principal provisions of which are described below.
 
     Clean Water Regulations. OPA 90 established an extensive regulatory and
liability regime for the protection of the environment from oil spills. OPA 90
affects all owners and operators of vessels in United States waters, which
include the United States territorial sea and the 200-mile exclusive economic
zone of the United States. Although it applies in general to all vessels, for
purposes of its liability limits and financial-responsibility and
response-planning requirements, OPA 90 differentiates between tank vessels
(which include the Company's chemical carriers, product carrier, and fuel
barges) and "other vessels" (which include the Company's tugs and offshore
energy service vessels).
 
     Under OPA 90, owners, operators, and certain charterers of vessels are
"responsible parties" and are jointly, severally, and strictly liable for
containment and cleanup costs and other damages arising from oil spills relating
to their vessels, unless the spill results solely from the act or omission of a
third party, an act of God, or an act of war. Such "other damages" are defined
broadly to include (i) natural resources damages and the costs of assessment
thereof; (ii) damages for injury to, or economic losses resulting from the
destruction of, real and personal property; (iii) net loss of taxes, royalties,
rents, fees, and other lost revenues by the U.S. government, a state, or
political subdivision thereof; (iv) lost profits or impairment of earning
capacity due to property or natural resources damage; (v) net cost of public
services necessitated by a spill response, such as protection from fire or other
hazards; and (vi) loss of subsistence use of natural resources.
 
     For tank vessels, the statutory liability of responsible parties is limited
to the greater of $1,200 per gross ton or $10 million ($2 million for a vessel
of 3,000 gross tons or less) per vessel; for "other vessels," such liability is
limited to the greater of $600 per gross ton or $500,000 per vessel. Such
liability limits do not apply, however, to an incident proximately caused by
violation of federal safety, construction, or operating regulations or by the
responsible party's gross negligence or willful misconduct, or if the
responsible party fails to report the incident or to cooperate and assist in
connection with oil removal activities. Although the Company currently maintains
pollution liability insurance with coverage of $700 million per incident for its
tank vessels ($500 million per incident for its fuel barges), a catastrophic
spill could result in liability in excess of available insurance coverage,
resulting in a material adverse effect on the Company.
 
     Under OPA 90, with certain limited exceptions, all newly built or converted
tankers operating in United States waters must be built with double hulls, and
existing single-hull vessels must be phased out at some point, depending upon
their size, age and place of discharge, between 1995 and 2015 unless retrofitted
with double hulls. As a result of this phase-out requirement, as interpreted by
the U.S. Coast Guard, the Company's chemical carriers and its petroleum product
carrier will be required to cease transporting petroleum products over the next
19 years, and its fuel barges will cease transporting fuel in 2015. The
retirement dates of certain tankers may be extended by reducing their gross
registered tonnage and cargo capacity. There can be no assurance that the useful
life of any of the Company's vessels will be so extended.
 
     OPA 90 expanded pre-existing financial responsibility requirements and
requires vessel owners and operators to establish and maintain with the United
States Coast Guard evidence of insurance or qualification as a self-insurer or
other evidence of financial responsibility sufficient to meet their potential
liabilities under OPA 90. U.S. Coast Guard regulations require evidence of
financial responsibility demonstrated by insurance, surety bond, self-insurance,
or guaranty. The regulations also implement the financial responsibility
requirements of the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 ("CERCLA"), which imposes liability for discharges of
hazardous substances such as chemicals, by increasing the amount of financial
responsibility from $1,200 to $1,500 per gross ton. The Company has obtained
COFRs pursuant to the Coast Guard regulations for its product carrier and for
its chemical carriers through self-insurance and commercial insurance and as
guarantor for the fuel barges.
 
                                       46
<PAGE>   48
 
     OPA 90 also amended the Federal Water Pollution Control Act to require the
owner or operator of a tank vessel to prepare vessel response plans and to
contract with oil spill response organizations to remove to the maximum extent
practicable a worst-case discharge (loss of all cargo). The Company has complied
with both requirements. As is customary, the Company's oil spill response
contracts are executory in nature and are not activated unless required. Once
activated, the Company's pollution liability insurance covers the cost of spill
removal subject to overall coverage limitations and deductibles.
 
     OPA 90 expressly permits individual states to impose their own liability
regimes with respect to oil pollution incidents occurring within their
boundaries, and many states have enacted legislation providing for unlimited
liability for oil spills. Some states that have enacted such legislation have
not yet issued implementing regulations defining tanker owners' responsibilities
under the legislation. The Company does not anticipate that such legislation or
regulations will have any material impact on its operations.
 
     The Company manages its exposure to losses from potential discharges of
pollutants through the use of well-maintained and well-equipped vessels, safety
and environmental programs, and its insurance program, and believes that it will
be able to accommodate reasonably foreseeable environmental regulatory changes.
 
     There can be no assurance, however, that any new regulations or
requirements or any discharge of pollutants by the Company will not have an
adverse effect on the Company.
 
     Clean Air Regulations. The federal Clean Air Act of 1970, as amended by the
Clean Air Act Amendments of 1990, requires the Environmental Protection Agency
to promulgate standards applicable to the emission of volatile organic compounds
and other air pollutants. These standards are designed to reduce hydrocarbon
emissions released in the atmosphere and are implemented by the states through
State Implementation Plans for areas that are not in compliance with those
standards. The Company's vessels are subject to vapor control and recovery
requirements when loading petroleum cargoes in Louisiana and when loading,
unloading, ballasting, cleaning, and conducting other operations in certain
ports in Texas. The Company's chemical and petroleum product carriers are
equipped with vapor control systems that satisfy the state requirements. The
fuel barges are not equipped with, and are not operated in areas that require,
such systems.
 
     Coastwise Laws. Most of the Company's operations are conducted in the U.S.
domestic trade, which is governed by the coastwise laws of the United States
(principally, the Jones Act). The coastwise laws reserve marine transportation
(including harbor tug services) between points in the United States (including
drilling rigs fixed to the ocean floor in U.S. territorial waters) to vessels
built in and documented under the laws of the United States (U.S. flag) and
owned and manned by U.S. citizens. Generally, a corporation is deemed a citizen
for these purposes so long as (i) it is organized under the laws of the U.S. or
a state thereof, (ii) each of its president or other chief executive officer and
the chairman of its board of directors is a citizen, (iii) no more than a
minority of the number of its directors necessary to constitute a quorum for the
transaction of business are non-citizens, and (iv) 75% of the interest and
voting power in the corporation are held by citizens. Because the Company would
lose its privilege of operating its vessels in the U.S. domestic trade if
non-citizens were to own or control in excess of 25% of the Company's
outstanding capital stock, the Company's Articles of Incorporation contain
restrictions concerning foreign ownership of its stock. See "Description of
Capital Stock -- Foreign Ownership Restrictions." A coalition of shipper
interests opposed to the Jones Act announced in the summer of 1995 its intention
to seek changes to the Jones Act. Although the Company believes that it is
unlikely that the Jones Act will be substantially modified or repealed, there
can be no assurance that Congress will not substantially modify the Jones Act or
repeal it. Such changes could have a material adverse effect on the Company's
operations and financial condition.
 
     Occupational Health Regulations. The Company's vessel operations are
subject to occupational safety and health regulations issued by the Coast Guard.
Such regulations currently require the Company to perform extensive monitoring,
medical testing, and record keeping with respect to seamen engaged in the
handling of the various cargoes transported by the Company's chemical and
petroleum products carriers.
 
                                       47
<PAGE>   49
 
     Vessel Condition. The Company's chemical and petroleum products carriers,
offshore energy support vessels, seven of its tugs, and the fuel barges are
subject to periodic inspection and survey by, and drydocking and maintenance
requirements of, the Coast Guard and/or the American Bureau of Shipping, a
marine classification society whose periodic certification as to the
construction and maintenance of certain vessels is required in order to maintain
insurance coverage. All of the Company's vessels requiring certification to
maintain insurance coverage are certified.
 
     Oil Tanker Escort Requirements. Implementation of oil tanker escort
requirements of OPA 90 and pending state legislation are expected to introduce
certain performance or engineering standards on tugs to be employed as tanker
escorts. The Company believes its tractor tug will be able to comply with any
existing or currently anticipated requirements for escort tugs. Adoption of such
new standards could require modification or refitting of the tugs currently
operated by the Company to the extent such tugs are employed as tanker escorts.
The Company does not anticipate OPA 90 or state requirements to require
modification of tugs, such as the Company's, involved in harbor tug operations.
 
     The Company believes that it is currently in compliance in all material
respects with the environmental and other laws and regulations, including OSHA
shipyard requirements, to which its operations are subject and is unaware of any
pending or threatened litigation or other judicial, administrative, or arbitral
proceedings against it occasioned by any alleged non-compliance with such laws
or regulations. The risks of substantial costs, liabilities, and penalties are,
however, inherent in marine operations, and there can be no assurance that
significant costs, liabilities, or penalties will not be incurred by or imposed
on the Company in the future.
 
INSURANCE
 
     The Company's marine transportation services operations are subject to the
normal hazards associated with operating vessels carrying large volumes of cargo
or rendering services in a marine environment. These hazards include the risk of
loss of or damage to the Company's vessels, damage to third parties as a result
of collision, loss, or contamination of cargo, personal injury of employees,
pollution, and other environmental damages. The Company maintains insurance
coverage against these hazards. Risk of loss of or damage to the Company's
vessels is insured through hull insurance policies in amounts that approximate
fair market value. Vessel operating liabilities, such as collision, cargo,
environmental, and personal injury, are insured primarily through the Company's
participation in the Steamship Mutual Underwriting Association (Bermuda
Limited), a mutual insurance association under which the coverage against such
hazards is currently unlimited for each incident except in the case of
pollution, which is limited to $700 million (the maximum amount available) for
each incident involving the Company's chemical and petroleum products carriers
and $500 million with respect to its other vessels. Because it maintains mutual
insurance, the Company is subject to funding requirements and coverage
shortfalls in the event claims exceed available funds and reinsurance and to
premium increases based on prior loss experience.
 
LEGAL PROCEEDINGS
 
     The Company is party to two legal proceedings involving its chemical
carrier Seabulk America, one involving the Company's continued ability to
operate the vessel in the U.S. domestic trade, the other involving the cost of
completing the vessel.
 
     The Seabulk America was completed in 1990 by combining the stern portion of
the wrecked oil tanker Fuji with the forebody of the chemical barge portion of
the former integrated tug/barge Oxy Producer/Oxy 4102. The Company purchased the
stern portion of the Fuji in 1985 after the tanker had broken apart following an
explosion at sea, and had previously purchased the barge portion of the Oxy
Producer/Oxy 4102 after the tug portion separated from the barge and was lost at
sea. At the time of their respective acquisitions by the Company, neither vessel
was qualified to operate in the U.S. domestic trade. The Fuji was not qualified
because it was built in Japan and the U.S. coastwise laws generally exclude
foreign-built vessels from the U.S. domestic trade. The barge was not qualified
because (i) the Oxy Producer/Oxy 4102, although built in the United States, was
built with the assistance of federal subsidy, (ii) the barge was purchased by
the Company with certain tax-deferred funds, and (iii) the provisions of the
Merchant Marine Act, 1936, as amended,
 
                                       48
<PAGE>   50
 
authorizing the subsidy and tax-deferral programs involved exclude vessels that
have been the subject of the programs from operating in the U.S. domestic trade.
 
     An exception to the coastwise laws' exclusion of foreign-built vessels from
the U.S. domestic trade is the Wrecked Vessel Act, which provides that a
foreign-built vessel wrecked on the coast of the United States may become
qualified for the U.S. domestic trade if it is repaired in the United States at
a cost of at least three times its appraised salvaged value. In a series of
rulings between 1985 and 1987, the Coast Guard, which administers the Wrecked
Vessel Act, determined that the Fuji would qualify for domestic operation under
the Act if it were repaired in the United States, by combining it with the barge
portion of the Oxy Producer/Oxy 4102, at a cost of at least $11.5 million. Also
in 1987, the Maritime Administration, which administers the Merchant Marine Act,
determined that once the barge was incorporated into the rebuilt Fuji, the barge
would have lost its character as a vessel and the domestic-trading restrictions
applicable to vessels built with subsidy assistance and purchased with
tax-deferred funds would no longer be operative. In 1990, following the
Company's completion of the repair project, the Coast Guard determined that the
value of the repairs exceeded $20.0 million and that the repaired vessel was the
rebuilt Fuji, renamed Seabulk America, eligible to operate in the U.S. domestic
trade.
 
     In Keystone Shipping Co. v. United States, pending in the U.S. District
Court for the District of Columbia (Civil Action No. 90-2762), the plaintiffs,
competitors of the Company, in 1990 asked the court to invalidate the foregoing
Coast Guard and Maritime Administration determinations that the Seabulk America
is qualified to operate in the U.S. domestic trade. The Company, as the sole
beneficiary of those determinations, has intervened as a defendant in the suit.
In September 1992, the court upheld certain aspects of the Coast Guard
determinations, concluded that the agencies had provided insufficient
explanation to enable the court to determine the validity of the Maritime
Administration determinations and the remaining aspects of the Coast Guard
determinations, and remanded the matter to each agency for further explanation
of its respective determinations. Those explanations were provided by August
1994, and the plaintiffs have to date not renewed their requests for an order
declaring the agency determinations unlawful. Should plaintiffs renew such
requests and obtain such an order, the Seabulk America would be limited to
operations in the foreign trades, where, although it would be less competitive
than in the U.S. domestic trade, it would be eligible to receive
operating-differential subsidy under a currently inactive subsidy contract held
by the Company. The Company believes that plaintiffs' suit was without merit
and, should it be renewed, intends to continue vigorously to support the
government's defense of the agency determinations.
 
     In Norfolk Shipbuilding and Dry Dock Corporation v. Seabulk Transmarine
Partnership, Ltd., pending in the U.S. District Court for the Eastern District
of Louisiana (Civil Action No. 93-1312), one of the shipyards that contracted to
complete the Seabulk America for the Company is seeking to recover from the
Company approximately $6.1 million for alleged additions and changes to the
contract work and costs of alleged delay and disruption, in addition to $2.4
million of the $5.9 million contract price that the Company has withheld. In
addition, the shipyard is seeking legal fees and expenses and $10.0 million of
punitive damages. The Company has asserted counterclaims aggregating $5.6
million for contract deletions, unfinished and defective work, and liquidated
damages for late delivery. In 1993, when this suit was filed, the Company was
required to obtain a $5.6 million letter of credit in order to furnish a bond to
obtain the release of the Seabulk America, which had been arrested pursuant to
customary procedures in litigation involving vessels. The suit, which involves
numerous complex factual issues, is currently in the pre-trial discovery stage.
While the Company believes that the plaintiff's claims are without merit and
that its counterclaims are meritorious, there can be no assurance that the
ultimate resolution of the suit will not require some payment by the Company in
addition to the $3.6 million previously paid.
 
     The Company is also a defendant in a suit relating to certain of its
offshore supply boats pending in the Circuit Court of the 17th Judicial Circuit
of Florida, U.S. Offshore, Inc. v. Seabulk Offshore, Ltd. (No. 93-32963(09)).
The suit involves a claim by a former limited partner in the partnership that
owns eight of the supply boats seeking an unspecified amount of damages for
alleged breach of a contract by which the Company agreed to pay the plaintiff 5%
of the revenues (not to exceed $1.3 million) earned from the operation of the
boats during the 40 months ended March 31, 1994. The Company has paid the
plaintiff
 
                                       49
<PAGE>   51
 
   
approximately $769,000 pursuant to the contract and believes that the claim for
any additional amount is without merit.
    
 
     Affiliates of the Company have intervened in two parallel legal actions
brought by Kirby Corporation ("Kirby"), an operator of vessels with which the
five new product carriers in which the Company has an interest will compete,
seeking to have the construction project stopped. Kirby's actions allege that
the U.S. Maritime Administration acted unlawfully in guaranteeing, pursuant to
Title XI of the Merchant Marine Act, 1936, as amended ("Title XI"), the $215
million of ship financing bonds issued to finance the project, specifically
asserting that the Maritime Administration erroneously determined that the
project is economically sound and that the entities that will own the vessels
are U.S. citizens qualified to operate the vessels in the coastwise trade. The
Company believes the actions are without merit, has supported the U.S.
Department of Justice in obtaining dismissal of one of the actions, is
continuing to support the Department in defending against Kirby's appeal from
that dismissal and in seeking dismissal of the remaining action. Both actions
are currently pending in the United States Court of Appeals for the Fifth
Circuit, as Kirby Corporation v. United States (No. 96-60154) and Kirby
Corporation v. Pena (No. 96-20582).
 
     From time to time the Company is also party to litigation arising in the
ordinary course of its business, most of which is covered by insurance.
 
PROPERTIES
 
     The Company's principal offices are located in Fort Lauderdale, Florida,
where the Company leases approximately 36,000 square feet of office and shop
space under a lease that expires in 2009. In addition, the Company leases
facilities in Houston, Texas, Lafayette and Amelia, Louisiana, Mobile, Alabama,
and Port Canaveral and Green Cove Springs, Florida, to support its operations.
 
EMPLOYEES
 
     As of December 15, 1996, the Company had approximately 953 employees.
Management considers relations with employees to be satisfactory. The Seabulk
America, Seabulk Challenger, and Seabulk Magnachem are manned by approximately
108 officers and crew who are subject to collective bargaining arrangements. In
addition, the HMI Dynachem, HMI Petrochem, and HMI Astrachem are manned by
approximately 90 members of national maritime labor unions pursuant to an
agreement between the Company and a third party employer.

    EQUITY OWNERSHIP PLANS
 
     Long-Term Incentive Plan. The Company has reserved 1,000,000 shares of
Class A Common Stock for issuance under the Hvide Marine Incorporated Equity
Ownership Plan (the "Plan"). The Plan is administered by the Compensation
Committee. Subject to selection by the Compensation Committee, any key employee,
including executive officers, is eligible to participate in the Plan. The
benefits to be granted under the Plan may take the form of (i) incentive or
non-qualified stock options, (ii) stock awards subject to future vesting, (iii)
stock appreciation rights, (iv) phantom shares, or (v) performance unit awards.
Options granted under the Plan may not be exercised until vested and shares of
Common Stock may not be issued pursuant to any stock award until vested. The
Compensation Committee is empowered under the Plan to determine all terms and
provisions under which options, awards, and other rights are granted under the
Plan, including (i) the number of shares subject to each option, award, or
right, (ii) when the option, award, or right becomes exercisable, (iii) the
exercise price, and (iv) the duration of the option, award, or right, which
cannot exceed ten years. Upon consummation of the IPO, options were granted to
63 employees to purchase 771,000 shares of Class A Common Stock at an exercise
price of $12 per share. Such options have ten-year terms, with the exception of
an option to purchase 100,000 shares which has a five-year term, and all such
options will vest 25% each year over four years.
 
     Employee Stock Purchase Plan. The Company has reserved 500,000 shares of
Class A Common Stock for purchase over the next five years under its 1996
Employee Stock Purchase Plan. This plan permits employees to purchase stock at a
discount to market value and be eligible to receive favorable income tax
treatment of the discount under Section 423 of the Internal Revenue Code. Under
this plan, all employees working more than twenty hours weekly are eligible to
purchase reserved shares at a discount equal to 15% of market price. The market
cost of shares purchased by an employee under this plan may not exceed $25,000
per year.
 
DIRECTOR COMPENSATION AND OPTIONS
 
     Directors not employed by the Company are paid $2,000 per board meeting and
$1,500 per board committee meeting attended and are reimbursed by the Company
for reasonable out-of-pocket expenses incurred for attendance at such meetings
in accordance with Company policy. All committee chairmen not employed by the
Company are also paid an annual retainer of $3,000. In order to promote the
alignment of the directors' and the stockholders' financial interests, it is the
intent of the Board of Directors that each Director should initially acquire at
least 500 shares of Common Stock and should increase this ownership interest by
a minimum of 500 shares annually. Each director's ownership interest can be
achieved by the purchase of Common Stock on the open market, by stock grants, or
by the exercise of stock options. In this regard, the Company granted to each
director who was not an employee 500 shares of Class A Common Stock upon
consummation of the IPO, and intends to grant each such director 500 shares of
Class A Common Stock each year.
 
     Additionally, the Company adopted a stock option plan for directors (the
"Directors Plan") and reserved 70,000 shares of Class A Common Stock for
issuance under that plan. In 1996, options to purchase 35,000 shares of Class A
Common Stock were issued under the Directors Plan. Under the Directors Plan, all
directors not employed by the Company will annually be granted an option to
purchase 1,500 shares of Class A Common Stock with an exercise price equal to
the fair market value of the Class A Common Stock on the date of grant. The date
of grant for these options will be the first business day following the annual
meeting of stockholders. Also, the Company granted to each director not employed
by the Company upon consummation of the IPO and pursuant to the Directors Plan,
an option to purchase 5,000 shares of Class A Common Stock at an exercise price
of $12 per share. Directors elected to the Board in the future will each be
granted an option to purchase 5,000 shares with an exercise price equal to the
fair market value of the Class A Common Stock as of the first business day
following the stockholder meeting at which the director is elected to the Board.
All stock options under the Directors Plan will vest at the earliest of death,
disability, change-in-control, voluntary retirement from the Board at or after
age 62, completion of ten years service on the Board, or one year from the date
of grant. All directors have agreed not to sell any shares of Class A Common
Stock for 90 days after the date of the Prospectus without the written consent
of Donaldson, Lufkin & Jenrette Securities Corporation.
 
                                       56
<PAGE>   58
 
ANNUAL INCENTIVE PLAN
 
     The Company has established an annual incentive plan under which key
members of management will be awarded cash payments based upon the achievement
of certain performance goals. Each year, the chief executive officer will
recommend to the Compensation Committee a list of participants and performance
goals for each proposed participant. The performance goals will consist of an
objective element, which will be based upon financial objectives relating to the
Company as a whole and/or a component of the Company, and a discretionary
element, which will be established by a participant's supervisor and may be
financial or non-financial in nature. Participants will be awarded cash payments
based upon the extent to which they have met or exceeded their performance
goals.
 
NON-COMPETE AND BENEFITS AGREEMENTS
 
     The Company is party to a non-compete agreement dated September 28, 1994
with Hans J. Hvide, the founder of the Company and father of its current
Chairman, pursuant to which Mr. Hvide receives a fee of $185,000 per year
(subject to annual adjustments based on the Consumer Price Index) in exchange
for an agreement not to provide any services to any person in competition with
the Company. The non-compete agreement expires upon the earlier of September 30,
2014 or the death of Mr. Hvide. The non-compete agreement can be terminated by
the Company only if Mr. Hvide materially breaches the Agreement, and by Mr.
Hvide only if the Company fails to pay the non-compete fees. The Company is also
party to a post-retirement benefits agreement with Mr. Hvide pursuant to which
he receives the use of an automobile, major medical health insurance for himself
and for his spouse, the use of an office and secretarial assistance, and a
payment of $2,000 per month in lieu of other expenses. The term of the
post-retirement benefits agreement is for the life of Mr. Hvide except for major
medical health insurance for Mr. Hvide's spouse, which is for the life of Mr.
Hvide's spouse. In the event the Company terminates the non-compete agreement,
the post-retirement benefits agreement terminates automatically.
 
                              CERTAIN TRANSACTIONS
 
     The Company's Articles of Incorporation require that any material
transaction between the Company and any of its officers, directors, holders of
more than 5% of any class of its capital stock, or other affiliates be on terms
no less favorable than those that could be obtained from unaffiliated persons
and be approved by a majority of the independent and disinterested directors.
The Company believes that the transactions described below are on terms no less
favorable than those that could be obtained from unaffiliated persons. Furnished
below is information regarding certain transactions since January 1, 1993 in
which executive officers and directors of the Company have had an interest.
 
     In September 1994, the Company purchased all of the partnership interests
owned by certain directors, officers, and employees of the Company in Hvide
Offshore Services, Ltd. ("HOS") for $607,000 in cash and $1.0 million in
promissory notes (the "HOS Notes") and assumed the bareboat charter rights and
obligations of HOS, which charters were acquired by HOS at no cost. HOS was the
bareboat charterer of four offshore service vessels managed by the Company. See
"Description of Certain Indebtedness -- Long-Term Charter
Obligations -- Bareboat Charters" and "-- Acquisition Notes and Assumed
Indebtedness." The purchase price of these interests was based upon an
independent appraisal of the fair market value of the vessels being acquired.
The appraisal, which was based upon a market analysis, was conducted by Bassoe
Offshore (USA), Inc., a company with substantial experience in the maritime
industry. The general partner of HOS was Maritime Transport Development Corp.
("Maritime Transport"), a company wholly owned by Hans J. Hvide and for which J.
Erik Hvide serves as an officer and a director. The limited partners of HOS were
Messrs. Hans J. Hvide (32%), J. Erik Hvide (32%), Farmer (10%), Sweeney (7.5%),
Brauninger (10%), John Krumenacker (the Company's Controller) (5%), and Douglas
(2.5%). HOS has since been dissolved and the Company has assumed all of its
obligations. As a result of the cancellation of $0.1 million in principal amount
of the HOS Notes held by Messrs. J. Erik and Hans J. Hvide as described below,
immediately prior to the IPO there remained outstanding $0.9 million principal
amount of HOS Notes, of which $0.3 million was repaid in cash with a portion of
the proceeds of the IPO and $0.2 million was exchanged for shares of Class A
 
                                       57
<PAGE>   59
 
Common Stock valued at the IPO price. Accordingly, there remains outstanding a
$0.4 million balance on the HOS Notes which the Company intends to repay with a
portion of the proceeds of the Offering.
 
     Also in September 1994, the Company purchased for $781,000 in cash and an
aggregate of $1,089,000 in promissory notes (the "HCL Notes") partnership
interests owned by certain directors, officers, and employees of the Company in
(i) Hvide Chartering, Ltd. ("HCL"), which owns the tug Hollywood (formerly the
Cape Canaveral) and chartered it to the Company; (ii) Hvide Leasing Partnership,
Ltd. ("HLP"), which owned office and computer equipment leased to the Company
(acquired by HLP in 1988 for $87,000); and (iii) HLP II, Ltd. ("HLP II"), which
owned office furniture and equipment leased to the Company (acquired by HLP II
in 1990 for $372,000). HLP and HLP II have since been dissolved. The purchase
price of the HCL interests was based upon an independent appraisal of the fair
market value of the Hollywood. The HCL appraisal, which was based upon a market
analysis, was conducted by Charles S. Smith, a marine consultant with
substantial experience in the maritime industry. The HLP and HLP II partnership
interests were purchased at book value, which the Company believes approximated
fair market value, for $20,000 and $93,000, respectively, in cash. The Company
believes that the book value approximated fair market value because the
interests were not liquid and had declining values which the Company believes
correspond with their depreciated book value. Messrs. Hans J. Hvide (33.33%), J.
Erik Hvide (20.0%), Farmer (2.67%), Sweeney (2.67%), Santos (2.67%), and Douglas
(2.67%) were limited partners of HCL. The Company was the sole general partner
of HCL and the owner of a 33.33% interest in that partnership. Messrs. J. Erik
Hvide (30%), Farmer (10%), Sweeney (5%), Santos (10%), and Douglas (5%) were the
limited partners of HLP. The Company was the sole general partner of HLP and the
owner of a 40.0% interest in that partnership. The Company, Mr. J. Erik Hvide
(14.29%), and Mr. Farmer (14.29%) were the limited partners of HLP II. As a
result of the cancellation of $0.8 million in principal amount of the HCL Notes
held by Messrs. J. Erik and Hans J. Hvide as described below, immediately prior
to the IPO there remained outstanding $0.3 million principal amount of HCL
Notes, of which $0.1 million was exchanged for shares of Class A Common Stock
valued at the IPO price. Accordingly, there remains outstanding a $0.2 million
balance on the HCL Notes which the Company intends to repay with a portion of
the proceeds of the Offering.
 
     In September 1994, the Company redeemed its outstanding preferred stock,
all of which was owned by Hans J. Hvide, at its par value in exchange for $2.4
million in cash and a $3.6 million promissory note (the "Founder's Note"). The
Company repaid $1.6 million of outstanding principal and accrued interest on the
Founder's Note with a portion of the proceeds from the IPO. Accordingly, there
remains a $2.0 million balance on the Founder's Note which the Company intends
to repay with a portion of the proceeds of the Offering.
 
     As of December 31, 1995, J. Erik Hvide was indebted to Maritime Transport
in the amount of $675,000 as a result of miscellaneous personal advances made to
him over a number of years. In 1996, Mr. Hvide guaranteed repayment of a like
portion of approximately $0.9 million owed to the Company by Maritime Transport.
All amounts owed to the Company by Maritime Transport, including the amount
guaranteed by Mr. Hvide, were repaid upon the consummation of the IPO by the
cancellation of $0.8 million of the HCL Notes and $0.1 million of the HOS Notes
held by Mr. Hvide and Hans J. Hvide.
 
     In September 1994, the Company issued to the Investor Group $25.0 million
aggregate principal amount of 12% Senior Notes due 2004 (the "Senior Notes") and
$25.0 million aggregate principal amount of 8% Junior Notes due 2014 (the
"Junior Notes") at discounts resulting in proceeds to the Company of
approximately $23.1 million and $17.5 million, respectively. In connection with
the issuance of the Senior Notes and the Junior Notes, the Company issued to
members of the Investor Group an aggregate of 452,518 shares of Class B Common
Stock and 313,215 shares of Class C Common Stock, and in connection with the
issuance of the Junior Notes agreed to issue to them up to 554,495 additional
shares of Common Stock (to be contributed by J. Erik Hvide and the Hvide Trusts)
to the extent necessary to earn a specified return on their investment. The
issuance of the Senior Notes and Common Stock issued in connection with the
Senior Notes resulted in total proceeds to the Company of $25.0 million, and the
issuance of Junior Notes and the Common Stock and CSIs (as defined herein)
issued in connection with the Junior Notes resulted in total proceeds to the
Company of $25.0 million. In addition, J. Erik Hvide and the Investor Group are
parties to an agreement granting them certain voting and approval rights,
including the right to nominate eight and three persons,
 
                                       58

respectively, to the Company's 11-member Board of Directors. The Company repaid
$15.8 million on the Senior Notes and $15.1 million on the Junior Notes with a
portion of the proceeds of the IPO. The outstanding principal amount of the
Junior Notes not repaid with the proceeds of the IPO was exchanged for shares of
Class A Common Stock and Class B Common Stock and certain shares of Class B
Common Stock and all shares of Class C Common Stock held by the Investor Group
were converted into shares of Class A Common Stock or Class B Common Stock. The
Company made aggregate cash payments on the Senior Notes during 1995 in the
approximate amount of $3.0 million. The remaining $10.2 million of accrued
interest on and principal of the Senior Notes, all of which are held by the
Investor Group, will be repaid with part of the proceeds of the Offering. In
addition, the Company agreed to pay an annual advisory fee of $100,000 to the
Investor Group. Such fee was paid in full in 1995 and in a pro rata amount of
$25,000 for 1994. Following the IPO, the amount of the fee was reduced by the
compensation received by Messrs. Calhoun and Lee in their capacities as
directors of the Company. For additional information concerning relationships
and transactions between the Company and the Investor Group, see "Use of
Proceeds," "Management -- Director Compensation and Options," "Description of
Capital Stock -- Shareholders Agreement," "-- Contingent Share Issuance
Agreement," and "-- Recapitalization Agreement."
    
 
   
     Certain members of the Investor Group are selling an aggregate of 139,416
shares of Common Stock in the Offering. See "Principal and Selling
Stockholders."
    
 
   
     Maritime Transport is the successor in interest to the entity which
developed and engineered and provides marketing services for the CATUG(R) vessel
design. Maritime Transport receives a commission equal to 1.25% of charter hire
received by the Company for the Seabulk Challenger and the Seabulk Magnachem as
payment for those development and engineering services. For each of the years
ended December 31, 1993, 1994, and 1995, the Company made payments to Maritime
Transport of $0.2 million.
    
 
     In November 1996, the Company took delivery of a 152-foot crew/supply boat,
named Seabulk St. Frances, which it purchased from J. Erik Hvide and the
Investor Group for a purchase price of approximately $2.2 million, which was
equal to their cost of the vessel.
 
     The Company has verbal arrangements with Jean Fitzgerald and Gerald Farmer
to provide technical and financial consulting services, respectively, to the
Company. Mr. Fitzgerald, whose arrangement commenced in February 1994, is
currently compensated for such services at the rate of $6,500 per month, and
received total compensation of $66,000 during 1995. Mr. Farmer, whose
arrangement commenced in December 1995, is compensated at an hourly rate. Both
arrangements may be terminated by either party without prior notice.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
     The following is a description of the principal terms of certain of the
Company's indebtedness, including indebtedness to be repaid with a portion of
the proceeds of the Offering. Copies of the definitive agreements setting forth
the terms of this indebtedness have been filed as exhibits to the Registration
Statement relating to the IPO. The following summaries of certain provisions of
the agreements do not purport to be complete and are subject to, and are
qualified in their entirety by reference to, all the provisions of the
agreements.
 
CREDIT FACILITY
 
     The Company's outstanding indebtedness under the Credit Facility was $70.2
million at September 30, 1996. The Credit Facility provides for a $60.5 million
term loan, a $10.0 million revolving line of credit, a $19.9 million vessel
acquisition credit line, and a $5.6 million letter of credit, all maturing
January 15, 2001, with the exception of the letter of credit, which matures on
January 15, 2000. Advances under the vessel acquisition credit line are not
permitted to exceed either (i) 70% of the lesser of the purchase price or
appraised value of the vessel being acquired, or (ii) a multiple of six times
EBITDA of the acquisition, and the amount of available credit will decrease to
$11.5 million over a four-year period, during which time the Company will be
required to make quarterly installment payments equal to the reduction in the
available commitment.
 
   
     Borrowings under the Credit Facility bear interest at prime or LIBOR, at
the Company's option, plus a margin based upon certain financial ratios. Such
borrowings were accruing interest at approximately 8.2% at September 30, 1996.
Based on the outstanding borrowings at September 30, 1996 and the current
amortization schedule, annual principal payments under the term loan will be
$7.0 million in 1997, $9.0 million in 1998, $11.0 million in 1999, $13.0 million
in 2000, with the remaining $18.5 million due January 15, 2001. All borrowings
are secured by preferred ship mortgages on all vessels owned by the Company,
assignments of all of the Company's receivables and earnings, and collateral
mortgages of spare parts, supplies, and fuel.
    
 
                                       61
<PAGE>   63
 
     The letter of credit serves as collateral for a surety bond to ensure
payment of any final judgment in the pending litigation relating to the
reconstruction of the Seabulk America. See "Business -- Legal Proceedings" and
Note 5 to the Company's consolidated financial statements.
 
     Covenants under the Credit Facility, among other things, (i) require the
Company to meet certain financial tests, including tests requiring the
maintenance of minimum interest coverage ratios, leverage ratios, levels of
liquidity, and cash flow ratios; (ii) require the Company to maintain certain
levels of collateral securing amounts outstanding under the Credit Facility;
(iii) limit the incurrence of additional indebtedness; (iv) limit purchases of
capital equipment and other capital expenditures; (v) restrict payments,
including dividends, with respect to shares of any class of capital stock; and
(vi) limit certain corporate acts of the Company, such as incurring debt,
creating liens, and entering into certain types of business transactions,
including mergers and joint ventures. The limitation on mergers generally
prohibits mergers other than acquisitions funded by the Credit Facility or
otherwise meeting certain requirements for such acquisitions, including the
requirements described above.
 
     Events of default under the Credit Facility include, among other things,
(i) any failure to pay principal thereunder when due, or to pay interest or fees
within three business days after the date due; (ii) the breach of certain
covenants or the inaccuracy of certain representations or warranties made under
the Credit Facility; (iii) any failure to pay amounts due on certain
indebtedness, or defaults that result in or permit the acceleration of such
indebtedness; (iv) certain events of bankruptcy, insolvency, or dissolution; (v)
certain judgments or orders; (vi) certain seizures, condemnations, or similar
actions pertaining to the Company's assets or business; (vii) the invalidity of
the security interests granted under the Credit Facility; and (viii) a Change in
Control (as defined herein).
 
     The Credit Facility limits the Company's annual capital expenditures,
including capital expenditures respecting maintenance and improvements of
existing vessels, to $13.0 million without the consent of the lending banks.
This limitation excludes (i) acquisitions made with the $19.9 million vessel
acquisition credit line, (ii) additional indebtedness of $10.0 million that the
Company is permitted to incur outside the Credit Facility, (iii) acquisitions
financed with proceeds of the Offering, and (iv) the payment of amounts
necessary to retire the Senior Notes, the Junior Notes, and certain related
party notes.
 
   
     The Company has entered into a commitment letter with its banks providing
for an amendment to the Credit Facility that would, upon consummation of the
Offering, (i) increase the amount available under the revolving line of credit
to $20.0 million, (ii) increase the amount available under the vessel
acquisition credit line to $50.0 million, (iii) permit financing of 100% of the
purchase price of a vessel with borrowings under the vessel acquisition credit
line, (iv) eliminate the limit on capital expenditures, (v) increase the limit
on additional indebtedness to $30.0 million, and (vi) reduce the interest rate
to LIBOR plus 1.25% per annum or prime plus 0.25% per annum, at the Company's
election. The effectiveness of this amendment is subject to the consummation of
the Offering.
    
 
LONG-TERM CHARTER OBLIGATIONS
 
     Title XI Bonds. Two of the Company's subsidiaries are parties to long-term,
"hell or high water" charters of the Seabulk Challenger and the Seabulk
Magnachem, the performance of which is guaranteed by the Company. Both vessels
were financed by the issuance of U.S. Government Guaranteed Ship Financing Bonds
issued pursuant to Title XI in leveraged lease transactions. As of December 31,
1996, the total remaining outstanding obligations of the Company under the
charters for the Seabulk Challenger and Seabulk Magnachem are $4.3 million and
$10.6 million, respectively. The Company's aggregate payments due under such
charters for 1997 and 1998 are $3.2 million and $3.3 million, respectively. The
long-term charter for the Seabulk Challenger is coterminous with the maturity
date of the respective obligation, and the charter for the Seabulk Magnachem
terminates in 2002. The Company has the option to purchase the vessels or renew
the charters at fair market value and, with respect to the Seabulk Magnachem,
has the right to share in the residual value proceeds of any sale to a third
party.
 
                                       62
<PAGE>   64
 
     In connection with the acquisition of the OMI Chemical Carriers, the
Company assumed approximately $34.7 million of U.S. Government Guaranteed Ship
Financing Bonds issued pursuant to Title XI in five distinct series bearing
interest at an average rate of 7.65%.
 
     Repayment of the Company's Title XI bonds is guaranteed by the full faith
and credit of the United States, acting through the Maritime Administration. As
security for such guarantee, the vessels are mortgaged to the United States, and
the subsidiaries that own or charter the vessels are each party to a security
agreement and a financial agreement with the United States containing various
operating covenants and financial conditions that, among other things, restrict
the ability of each to (i) incur additional indebtedness, (ii) make certain
loans, advances, or investments, (iii) create certain liens, (iv) pay stock
dividends, (v) sell, transfer, or dispose of assets, (vi) change the nature of
its business, (vii) make capital expenditures, (viii) effect certain mergers,
consolidations, or similar business combinations, or (ix) enter into certain
vessel charter arrangements. The agreements specify various events of default,
including failure to pay charter hire, pay certain guarantee fees, satisfy
certain covenants, maintain required insurance, and maintain U.S. citizenship
(within the meaning of Section 2 of the Shipping Act, 1916) and certain events
of insolvency or bankruptcy.
 
     Bareboat Charters. The Company is party to bareboat charters relating to
four offshore service vessels, two of which expire in June 2001 and two of which
expire in January 2002. See "Certain Transactions" and Note 4 to the Company's
consolidated financial statements. The Company has an option to purchase each of
these vessels for a nominal amount upon the expiration of the charters. The
Company is also party to two bareboat charters relating to a total of nine crew
boats. The charter on one crew boat expires in 2002 with an option to purchase
the vessel for $0.4 million. The charter on the remaining eight crew boats
expires in 2004 with an option to purchase the vessels for a nominal amount. In
addition, the Company is party to a bareboat charter on a tractor tug which
expires in 2010 with an option to purchase the vessel for $1.6 million.
 
                          DESCRIPTION OF CAPITAL STOCK
 
     The following summary description of the Company's capital stock is
qualified in its entirety by reference to the Articles of Incorporation and its
Amended and Restated Bylaws (the "Bylaws"), copies of which have been included
as exhibits to the Registration Statement relating to the IPO, and reference to
Florida law. All capitalized terms used and not defined below have the
respective meanings assigned to them in the Articles of Incorporation.
 
   
     The authorized capital stock of the Company consists of 100,000,000 shares
of Class A Common Stock, par value $.001 per share, of which 7,647,791 shares
are issued and outstanding, 5,000,000 shares of Class B Common Stock, par value
$.001 per share, of which 3,419,577 shares are issued and outstanding, and
10,000,000 shares of Preferred Stock, par value $1.00 per share, none of which
are issued and outstanding. Upon consummation of the Offering, there will be
issued and outstanding 11,508,375 shares of Class A Common Stock, 3,419,577
shares of Class B Common Stock, and no shares of Preferred Stock.
    
 
COMMON STOCK
 
     The holders of Common Stock are entitled to receive such dividends, in
cash, property or securities, as may be declared from time to time by the Board
of Directors out of funds legally available therefor. The holders of Common
Stock are entitled to participate in dividends ratably on a per share basis. If
dividends consist of Common Stock or other voting securities of the Company, the
voting rights of each such security shall correspond to the voting rights of the
security held. Any dividend declared for one class of Common Stock must be
declared for the other classes of Common Stock. The holders of Common Stock have
no preemptive or redemption rights and are not subject to future calls or
assessments by the Company. Subject to the prior rights of holders, if any, of
any outstanding class or series of capital stock having a preference in relation
to the Common Stock as to distributions upon dissolution, liquidation, and
winding-up of the Company, holders of Common Stock are entitled to share ratably
in any assets of the Company that remain after payment in full of all debts and
liabilities of the Company.
 
                                       63
<PAGE>   65
 
     The holders of Class A Common Stock and Class B Common Stock vote together
as a single class on all matters submitted to a vote of the stockholders,
including the election of directors, except as described below under "-- Foreign
Ownership Restrictions" and as provided under Florida law. In all matters
submitted to a vote of the stockholders, including the election of directors,
and except as described below under "-- Foreign Ownership Restrictions" and
under "-- Certain Provisions of Articles of Incorporation and Bylaws," each
share of Class A Common Stock is entitled to one vote and each share of Class B
Common Stock is entitled to ten votes. The stockholders do not have cumulative
voting rights.
 
     The Class B Common Stock can be owned only by (i) J. Erik Hvide and,
subject to certain limitations set forth in the Articles of Incorporation, any
person related to him by kinship or marriage, trusts or similar arrangements
established solely on the behalf of one or more of them, and partnerships and
other entities that are wholly owned by them (collectively, the "Hvide Family");
or (ii) the Investor Group and its affiliates. If the ownership or beneficial
interest in any share of Class B Common Stock ceases to be vested in any of
these persons, then such share will automatically and immediately convert into a
share of Class A Common Stock, although such a conversion will not occur where
Class B Common Stock is transferred from one Hvide Family member, upon death, to
another Hvide Family member.
 
     Except as described below under "-- Foreign Ownership Restrictions," each
holder of Class B Common Stock may elect at any time to convert any of his
shares, share for share, into Class A Common Stock.
 
   
     Immediately after completion of the Offering, the Hvide Family and the
Investor Group will hold 51.7% and 48.3%, respectively, of the outstanding Class
B Common Stock. The Hvide Family and the Investor Group will thus own 11.9% and
12.5%, respectively, of the combined classes of Common Stock (11.3% and 12.0%,
respectively, if the Underwriters' over-allotment option is exercised in full)
and control 38.7% and 36.6%, respectively, of the voting power of such stock
upon completion of the Offering (37.9% and 36.3%, respectively, if the
Underwriters' over-allotment option is exercised in full) and will control the
management and affairs of the Company and any corporate actions requiring
stockholder approval.
    
 
   
PREFERRED STOCK
    
 
     The Board of Directors has the authority, without further action by the
stockholders, to issue from time to time shares of Preferred Stock in one or
more series and to fix, with respect to each series, the number of shares,
voting powers, designations, relative rights, preferences (including seniority
upon liquidation), privileges, and restrictions thereof. The rights,
preferences, privileges, and restrictions of different series of Preferred Stock
may differ with respect to dividend rates, amounts payable on liquidation,
voting rights, conversion rights, redemption provisions, sinking fund
provisions, and other matters. The Preferred Stock is subject to the dual stock
certificate system described below under "-- Foreign Ownership Restrictions."
 
     The issuance of Preferred Stock could decrease the amount of earnings and
assets available for distribution to holders of Common Stock, could adversely
affect the rights and powers, including voting and distribution rights, of
holders of Common Stock and could have the effect of delaying, deferring, or
preventing a change in control of the Company. Except as otherwise provided by
law, the holders of any series of Preferred Stock may be given the right, voting
separately as a class, to elect one or more directors of the Company. The term
of any such director would expire at the next succeeding annual meeting of
shareholders.
 
     The Company has no present intention to issue any shares of Preferred
Stock.
 
FOREIGN OWNERSHIP RESTRICTIONS
 
     The Articles of Incorporation (i) contain provisions limiting the aggregate
percentage ownership by Non-Citizens of each class of the Company's capital
stock (including the Class A Common Stock and the Class B Common Stock) to
24.99% of the outstanding shares of each such class (the "Permitted Percentage")
to ensure that such foreign ownership will not exceed the maximum percentage
permitted by applicable federal law (presently 25.0%), (ii) require institution
of a dual stock certificate system to help determine such ownership, and (iii)
permit the Board of Directors to make such determinations as may reasonably be
necessary to ascertain such ownership and implement such limitations. These
provisions are intended to
 
                                       64
<PAGE>   66
 
protect the Company's ability to operate its vessels in the U.S. domestic trade
governed by the Jones Act. The ability of the Company to so operate is necessary
to avoid default under certain of the Company's financings, may enhance the
Company's ability to incur additional debt, and may have other effects upon the
Company. See "Risk Factors -- Restriction on Foreign Ownership" and
"Business -- Environmental and Other Regulation -- Coastwise Laws."
 
     To provide a method to enable the Company reasonably to determine stock
ownership by Non-Citizens, the Articles of Incorporation require the Company to
institute (and to implement through the transfer agent for the Common Stock) a
dual stock certificate system, pursuant to which certificates representing
shares of Common Stock will bear legends that designate such certificates as
either "citizen" or "non-citizen," depending on the citizenship of the owner.
Accordingly, stock certificates are denominated as "citizen" (blue) in respect
of Class A Common Stock owned by Citizens and as "non-citizen" (red) in respect
of Class A Common Stock owned by Non-Citizens. The Company may also issue
non-certificated shares through depositories if the Company determines such
depositories have established procedures that allow the Company to monitor the
ownership of Common Stock by Non-Citizens.
 
     For purposes of the dual stock certificate system, a "Non-Citizen" is
defined as any person other than a Citizen, and a "Citizen" is defined as: (i)
any individual who is a citizen of the U.S. by birth, naturalization, or as
otherwise authorized by law; (ii) any corporation (a) organized under the laws
of the U.S., or a state, territory, district, or possession thereof, (b) of
which title to not less than 75% of its stock is beneficially owned by and
vested in Citizens, free from any trust or fiduciary obligation in favor of
Non-Citizens, (c) of which not less than 75% of the voting power is vested in
Citizens, free from any contract or understanding through which it is arranged
that such voting power may be exercised directly or indirectly in behalf of
Non-Citizens, (d) of which there are no other means by which control is
conferred upon or permitted to be exercised by Non-Citizens, (e) whose president
or chief executive officer, chairman of the board of directors and all officers
authorized to act in their absence or disability are Citizens, and (f) of which
more than 50% of that number of its directors necessary to constitute a quorum
are Citizens; (iii) any partnership (a) organized under the laws of the U.S., or
a state, territory, district, or possession thereof, (b) all general partners of
which are Citizens, and (c) of which not less than a 75% interest is
beneficially owned and controlled by, and vested in, Citizens, free and clear of
any trust or fiduciary obligation in favor of Non-Citizens; (iv) any association
(a) organized under the laws of the U.S., or a state, territory, district, or
possession thereof, (b) of which 100% of the members are Citizens, (c) whose
president, chief executive officer, or equivalent position, chairman of the
board of directors, or equivalent committee or body, and all persons authorized
to act in their absence or disability are Citizens, (d) of which not less than
75% of the voting power is beneficially owned by Citizens, free and clear of any
trust or fiduciary obligation in favor of Non-Citizens, and (e) of which more
than 50% of that number of its directors or equivalent persons necessary to
constitute a quorum are Citizens; (v) any limited liability company (a)
organized under the laws of the U.S., or a state, territory, district or
possession thereof, (b) of which not less than 75% of the membership interests
are beneficially owned by and vested in Citizens, free from any trust or
fiduciary obligation in favor of Non-Citizens, and the remaining membership
interests are beneficially owned by and vested in persons meeting the
requirements of 46 U.S.C. Sec. 12102(a), (c) of which not less than 75% of the
voting power is vested in Citizens, free from any contract or understanding
through which it is arranged that such voting power may be exercised directly or
indirectly in behalf of Non-Citizens, (d) of which there are no other means by
which control is conferred upon or permitted to be exercised by Non-Citizens,
(e) whose president or other chief executive officer or equivalent position,
chairman of the board of directors or equivalent committee or body, managing
members (or equivalent), if any, and all persons authorized to act in their
absence or disability are citizens, free and clear of any trust or fiduciary
obligation in favor of any Non-Citizens, and (f) of which more than 50% of that
number of its directors or equivalent persons necessary to constitute a quorum
are Citizens; (vi) any joint venture, if not an association, corporation,
partnership, or limited liability company (a) organized under the laws of the
U.S., or a state, territory, district, or possession thereof, and (b) of which
100% of the equity is beneficially owned and vested in Citizens, free and clear
of any trust or fiduciary obligation in favor of any Non-Citizens; and (vii) any
trust (a) domiciled in and existing under the laws of the U.S., or a state,
territory, district, or possession thereof, (b) the trustee of which is a
Citizen, and (c) of which not less than a 75% interest is held for the benefit
of Citizens, free and clear of any trust or fiduciary obligation in favor of any
Non-Citizens. The
 
                                       65
<PAGE>   67
 
foregoing definition is applicable at all tiers of ownership and in both form
and substance at each tier of ownership.
 
     Shares of Common Stock are transferable to Citizens at any time and are
transferable to Non-Citizens if, at the time of such transfer, the transfer
would not increase the aggregate ownership by Non-Citizens of that particular
class of Common Stock above the Permitted Percentage in relation to the total
outstanding shares of that particular class of Common Stock. Non-Citizen
certificates may be converted to Citizen certificates upon a showing,
satisfactory to the Company, that the holder is a Citizen. Any purported
transfer to Non-Citizens of shares or of an interest in shares of the Company
represented by a Citizen certificate in excess of the Permitted Percentage will
be ineffective as against the Company for all purposes (including for purposes
of voting, dividends, and any other distribution, upon liquidation or
otherwise). In addition, the shares may not be transferred on the books of the
Company, and the Company, whether or not such stock certificate is validly
issued, may refuse to recognize the holder thereof as a stockholder of the
Company except to the extent necessary to effect any remedy available to the
Company. Subject to the foregoing limitations, upon surrender of any stock
certificate for transfer, the transferee will receive citizen (blue)
certificates or non-citizen (red) certificates, as applicable.
 
     The Articles of Incorporation establish procedures with respect to the
transfer of shares to enforce the limitations referred to above and authorize
the Board of Directors to implement such procedures. The Board of Directors may
take other ministerial actions or make interpretations of the Company's foreign
ownership policy as it deems necessary in order to implement the policy.
Pursuant to the procedures established in the Articles of Incorporation, as a
condition precedent to each issuance and/or transfer of stock certificates
representing shares of Common Stock (including the shares of Class A Common
Stock being sold in the Offering), a citizenship certificate will be required
from all transferees (and from any recipient upon original issuance) of Common
Stock and, with respect to the beneficial owner of the Common Stock being
transferred, if the transferee (or the original recipient) is acting as a
fiduciary or nominee for such beneficial owner. The registration of the transfer
(or original issuance) will be denied upon refusal to furnish such citizenship
certificate, which must provide information about the purported transferee's or
beneficial owner's citizenship. Furthermore, as part of the dual stock
certificate system, depositories holding shares of the Company's Common Stock
will be required to maintain separate accounts for "Citizen" and "Non-Citizen"
shares. When the beneficial ownership of such shares is transferred, the
depositories' participants will be required to advise such depositories as to
which account the transferred shares should be held. In addition, to the extent
necessary to enable the Company to determine the number of shares owned by
Non-Citizens, the Company may from time to time require record holders and
beneficial owners of shares of Common Stock to confirm their citizenship status
and may, in the discretion of the Board of Directors, temporarily withhold
dividends payable to, and deny voting rights to, any such record holder or
beneficial owner until confirmation of citizenship is received.
 
     Should the Company (or its transfer agent for the Common Stock) become
aware that the ownership by Non-Citizens of Common Stock at any time exceeds the
Permitted Percentage (the "Excess Shares"), the Board of Directors is authorized
to withhold dividends and other distributions temporarily on the Excess Shares,
pending the transfer of such shares to a Citizen or the reduction in the
percentage of shares owned by Non-Citizens to or below the Permitted Percentage,
and to deny voting rights with respect to the Excess Shares. If dividends and
distributions are to be withheld, they will be set aside for the account of the
Excess Shares. At such time as such shares are transferred to a Citizen or the
ownership of such shares by Non-Citizens will not result in aggregate ownership
by Non-Citizens in excess of the Permitted Percentage, the dividends withheld
shall be paid to the then record holders of the related shares. Excess Shares
shall, so long as the excess exists, not be deemed to be outstanding for
purposes of determining the vote required on any matter brought before the
stockholders for a vote. The Articles of Incorporation provide that the Board of
Directors has the power, in its reasonable discretion and based upon the records
maintained by the Company's transfer agent, to determine those shares of Common
Stock that constitute the Excess Shares. Such determination will be made by
reference to the date or dates on which such shares were purchased by Non-
Citizens, starting with the most recent acquisition of shares by a Non-Citizen
and including, in reverse chronological order, all other acquisitions of shares
by Non-Citizens from and after the acquisition that first
 
                                       66
<PAGE>   68
 
caused the Permitted Percentage to be exceeded; provided that Excess Shares
resulting from a determination that a record holder or beneficial owner is no
longer a Citizen will be deemed to have been acquired as of the date of such
determination. To satisfy the Permitted Percentage described above, the Articles
of Incorporation authorize the Board of Directors, in its discretion, to redeem
(upon written notice) Excess Shares in order to reduce the aggregate ownership
by Non-Citizens to the Permitted Percentage. As long as the shares of Class A
Common Stock offered hereby continue to be authorized for quotation on the
Nasdaq National Market, the redemption price will be the average of the closing
sale price of the shares (as reported by the Nasdaq National Market) during the
30 trading days next preceding the date of the notice of redemption. The
redemption price for Excess Shares will be payable in cash. In the event the
Company is not permitted by applicable law to make such redemption or the Board
of Directors, in its discretion, elects not to make such redemption, the Company
will give notice to the holders of Class B Common Stock and those of whom are
Citizens may elect to purchase their pro rata portion of the Excess Shares by
delivering written notice of such election within 30 days of receipt of the
Company's notice.
 
POSSIBLE ANTI-TAKEOVER PROVISIONS
 
     Florida Business Corporation Act. The Company is subject to Sections
607.0901 and 607.0902 of the Florida Business Corporation Act ("FBCA"), which
regulate the acquisition and exercise of corporate control.
 
     Under Section 607.0902 of the FBCA, "control shares" of certain
corporations acquired in a "control share acquisition," with certain exceptions,
have no voting rights unless such rights are granted pursuant to a vote of the
holders of a majority of the corporation's voting stock (excluding all
"interested shares"). "Control shares" are shares that, when added to all other
shares which a person owns or has the power to vote, would give that person any
of the following ranges of voting power: (i) one-fifth or more but less than
one-third of the voting power; (ii) one-third or more but less than a majority
of the voting power; and (iii) more than a majority of the voting power. A
"control share acquisition" is the acquisition of ownership of, or the power to
vote, outstanding control shares. Shares acquired within 90 days, or as part of
a plan to effectuate a control share acquisition, are deemed to have been
acquired in the same transaction. "Interested shares" include shares held by the
person attempting to effectuate the control share acquisition or any officer or
employee-director of the corporation. A corporation may elect to not be governed
by Section 607.0902 of the FBCA in its articles of incorporation or bylaws.
 
     Section 607.0901 of the FBCA requires that certain transactions between an
interested stockholder (in general, a stockholder that beneficially owns more
than 10% of a corporation's outstanding voting stock) and a corporation be
approved by the affirmative vote of the holders of two-thirds of the
corporation's voting shares (excluding those shares beneficially owned by the
interested stockholder). In general, such approval will not be required if the
transaction is approved by a majority of disinterested directors, the interested
stockholder has been the beneficial owner of at least 80% of the corporation's
outstanding voting stock for at least the preceding five years, the interested
stockholder is the beneficial owner of at least 90% of the outstanding voting
stock of the corporation (excluding stock acquired directly from the corporation
in a transaction not approved by a majority of the disinterested directors), or
the consideration paid in the affiliated transaction satisfies the statutory
"fair price" formula and certain other conditions are met. Transactions covered
by Section 607.0901 include mergers, consolidations, sales of assets having an
aggregate fair market value of 5% or more of the aggregate fair market value of
all the corporation's assets on a consolidated basis or of all the corporation's
outstanding stock or representing 5% or more of the corporation's earning power
or net income on a consolidated basis, transfers of shares having an aggregate
fair market value of 5% or more of the aggregate fair market value of all
outstanding shares of the corporation, liquidations, dissolutions,
reclassifications, recapitalizations, and loans. A corporation may elect, by the
vote of a majority of the outstanding voting stock (not including shares held by
an interested stockholder), by amending such corporation's articles of
incorporation or bylaws, to not be subject to the provisions of Section 607.0901
of the FBCA. Any such election, however, will not be effective until 18 months
after it is made, and will not apply to any affiliated transaction between such
corporation and someone who was an interested stockholder prior to the effective
date of such amendment.
 
                                       67
<PAGE>   69
 
     Each of the foregoing provisions of the FBCA could have the effect of
delaying or making it more difficult to effect a change of control or management
of the Company, even though such a change may be beneficial to the Company and
its stockholders.
 
     Dual Classes of Common Stock. The Class A Common Stock entitles its holders
to one vote per share, and the Class B Common Stock entitles its holders to ten
votes per share. Accordingly, upon consummation of the Offering, the Hvide
Family, as the holder of all the outstanding Class B Common Stock, will be able
to control the vote on all matters submitted to a vote of the holders of the
Common Stock, and such control may have the effect of discouraging certain types
of transactions involving an actual or potential change of control of the
Company, including transactions in which the holders of Class A Common Stock
might otherwise receive a premium for their shares over then-current market
prices.
 
   
     Board of Directors. In all elections of directors, except elections, if
any, for directors for Preferred Stock, as described in "-- Preferred Stock,"
the holders of the Class A Common Stock and Class B Common Stock vote together
as a class, with each share of Class A Common Stock entitled to one vote and
each share of Class B Common Stock entitled to ten votes. Neither class has
cumulative voting rights. As a result of their ownership of Class B Common
Stock, the Hvide Family and the Investor Group will, upon consummation of the
Offering, have the ability to elect all of the members of the Company's Board of
Directors. Under the terms of the Shareholders Agreement, the Hvide Family and
the Investor Group have the ability to nominate eight and three persons,
respectively, to the Company's 11-member Board of Directors. In addition,
pursuant to the Articles of Incorporation, the Board of Directors is divided
into three classes of directors serving staggered three-year terms as well as
directors, if any, for Preferred Stock who serve one-year terms. As a result,
approximately one third of the Board of Directors is elected each year. Each of
these provisions could have the effect of delaying or making it more difficult
to effect a change in control or management of the Company, even though such a
change may be beneficial to the Company and its stockholders.
    
 
     Restrictions on Taking Stockholder Action. The Company's Bylaws provide
that a stockholder must notify the Company in advance of such holder's intent to
bring up items of business or nominate directors at any annual meeting of
stockholders. With respect to other items of business, the Bylaws provide that a
stockholder's notice must be given in accordance with the procedures set forth
in Rule 14a-8 of Regulation 14A under the Securities Exchange Act of 1934, as
amended, which generally requires that such proposals be received by the Company
not less than 120 days prior to the anniversary date that proxy solicitation
materials were sent out for the immediately preceding annual meeting of
stockholders of the Company. As permitted by the FBCA, pursuant to the Company's
Articles of Incorporation, stockholders may only call a special meeting of
stockholders when the holders of not less than 50% of the shares entitled to
vote make written demand on the Company for such a meeting.
 
     Authorized but Unissued Capital Stock. One of the effects of the existence
of authorized but unissued Common Stock and undesignated Preferred Stock may be
to enable the Board of Directors to make more difficult or to discourage an
attempt to obtain control of the Company by means of a merger, tender offer,
proxy contest, or otherwise, and thereby to protect the continuity of the
Company's management. If, in the exercise of its fiduciary obligations, the
Board of Directors were to determine that a takeover proposal was not in the
Company's best interest, such shares could be issued by the Board of Directors
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 acquiror 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 Board
of Directors, by effecting an acquisition that might complicate or preclude the
takeover, or otherwise. In this regard, the Articles of Incorporation grant the
Board of Directors broad power to establish the rights and preferences of the
authorized and unissued Preferred Stock, one or more series of which could be
issued entitling holders (i) to vote separately as a class on any proposed
merger or consolidation, (ii) to cast a proportionately larger vote together
with the Common Stock on any such transaction or for all purposes, (iii) to
elect directors having terms of office or voting rights greater than those of
other directors, (iv) to convert Preferred Stock into a greater number of shares
of Common Stock or other securities, (v) to demand redemption at a specified
price under prescribed circumstances related to a change of control, or (vi) to
exercise other rights designated to impede a takeover. The issuance of shares of
Preferred
 
                                       68
<PAGE>   70
 
Stock pursuant to the Board of Directors' authority described above may
adversely effect the rights of holders of the Common Stock.
 
CERTAIN PROVISIONS OF ARTICLES OF INCORPORATION AND BYLAWS
 
     Rights of Approval. So long as the Investor Group owns at least 5% of the
Company's outstanding Class B Common Stock, subject to the following exception,
the following actions must be approved by holders of at least 95% of the Class B
Common Stock: (i) engagement of the Company or its subsidiaries in any material
new business; (ii) a merger involving the Company or a sale of all or
substantially all of the Company's assets; (iii) a recapitalization or voluntary
bankruptcy filing; (iv) a capital investment, acquisition, or asset sale in
excess of $5.0 million; (v) borrowings or issuances of securities in excess of
$5.0 million; or (vi) amendment to the Articles of Incorporation reducing or
delegating the authority of the Board of Directors or affecting the rights of
holders of shares of Class B Common Stock. After September 30, 1999, however, a
merger or sale of substantially all of the Company's assets no longer will
require the approval of holders of 95% of the Class B Common Stock. In addition,
so long as the Investor Group owns at least 25% of the Company's outstanding
Class B Common Stock, the appointment of a new chief executive officer must be
approved by the holders of at least 75% of the Class B Common Stock.
 
   
     Liability of Directors and Officers. The FBCA permits corporations to (i)
include provisions in their articles of incorporation that limit the personal
liability of directors for monetary damages resulting from breaches of the duty
of care, subject to certain exceptions, and (ii) indemnify directors and
officers, among others, in certain circumstances for their expenses and
liabilities incurred in connection with defending pending or threatened suits.
    
 
     The Articles of Incorporation include a provision that eliminates the
personal liability of a director to the Company and its stockholders for
monetary damages resulting from breaches of the duty of care to the fullest
extent permitted by the FBCA and further provide that any amendment or repeal of
that provision will not adversely affect any right or protection of a director
of the Company existing at the time of such amendment, modification, or repeal
to any director for acts or omissions occurring prior to such amendment.
 
     Pursuant to the Articles of Incorporation, the Board of Directors has
indemnified the Company's current and former directors, officers, employees, and
agents to the fullest extent permitted, from time to time, under the FBCA as
presently or hereafter in effect. The Company also may enter into agreements
providing for greater or different indemnification of any of these persons. The
Company maintains an insurance policy covering the liability of its directors
and officers for actions taken in their official capacity.
 
     Citizenship of Directors and Officers. The Company's Bylaws provide that
the Chairman of the Board of Directors, Chief Executive Officer, President, and
all Vice Presidents must be Citizens, and restrict any officer who is not a
Citizen from acting in such capacities in the absence or disability of such
persons. The Bylaws further provide that the number of Non-Citizen directors
shall not exceed a minority of the number necessary to constitute a quorum for
the transaction of business. See "Business -- Environmental and Other
Regulation -- Coastwise Laws."
 
RECAPITALIZATION AGREEMENT
 
   
     The Company, the Investor Group, J. Erik Hvide, and the Hvide Trusts
entered into a recapitalization agreement (the "Recapitalization Agreement") in
connection with the IPO. Under the Recapitalization Agreement, immediately prior
to the IPO, 74,704 shares of the 452,518 Class B Common Stock owned by the
Investor Group were converted into 74,704 shares of Class A Common Stock, the
313,215 shares of Class C Common Stock of the Company owned by the Investor
Group were converted into 229,062 shares of Class A Common Stock and 84,153
shares of Class B Common Stock and the 663,415 shares of Class C Common Stock
owned by J. Erik Hvide and the Hvide Trusts were converted into 663,415 shares
of Class B Common Stock. Contemporaneous with the IPO, the Board authorized the
retirement of the Class C Common Stock. In addition, under the Recapitalization
Agreement, $31.0 million of the proceeds of the IPO was used to repay $15.9
million of principal and accrued but unpaid interest on the Senior Notes and
$15.1 million of the principal and accrued but unpaid interest on the Junior
Notes. Under the Recapitalization Agreement, the
    
 
                                       69
<PAGE>   71
 
   
$13.9 million of remaining outstanding principal amount of the Junior Notes
following application of the proceeds of the IPO was converted into an aggregate
of 55,500 shares of Class A Common Stock and 1,188,502 shares of Class B Common
Stock. The parties are also parties to the Shareholders Agreement and the CSI
Agreement, each as described below.
    
 
SHAREHOLDERS AGREEMENT
 
   
     In connection with the September 30, 1994 issuance of the Senior Notes and
the Junior Notes, the Company, J. Erik Hvide, the Hvide Trusts, and the Investor
Group entered into an agreement granting certain voting and approval rights to
the Investor Group and the Hvide Family. Immediately prior to the IPO, that
agreement was terminated and Mr. Hvide, the Hvide Trusts, and the Investor Group
entered into a new agreement (the "Shareholders Agreement") that provides as
follows:
    
 
     Designations to the Board of Directors. The Investor Group may initially
nominate three persons to the Board of Directors and must vote all its shares so
as to elect eight other persons nominated to the Board of Directors by Mr. J.
Erik Hvide. Of these eight nominees, one will be Mr. Hvide, no more than three
others may be employees of the Company, its subsidiaries or members of the Hvide
Family, and the remainder must be independent of Mr. Hvide, the Company, and its
subsidiaries. In addition, J. Erik Hvide and the Hvide Trusts must vote their
shares to elect the three Investor Group nominees. The number of nominees that
the Investor Group is entitled to designate will be reduced by one at such times
as the Investor Group's Primary Economic Interest (as defined in the
Shareholders Agreement) drop below 20%, 10%, and 5%, respectively, of the
Company's outstanding Common Stock. The Investor Group may remove their
nominees, with or without cause, and may nominate successors to their nominees.
All director nominees must be U.S. citizens.
 
     Right of First Refusal. Mr. Hvide (together with the Hvide Trusts) and the
Investor Group, respectively, have granted a right of first refusal for each to
purchase the other's stock in certain circumstances.
 
     Share Adjustment. The Investor Group has agreed that, if following the
issuance of the CSIs (as defined below), the aggregate votes held by the
Investor Group by virtue of its ownership of Class A and Class B Common Stock
would exceed the votes held by the Hvide Family by virtue of its ownership of
Class A and Class B Common Stock, the Investor Group will convert sufficient
Class B Common Stock to Class A Common Stock to allow the Hvide Family to
maintain a one vote majority over the Investor Group.
 
   
CONTINGENT SHARE ISSUANCE AGREEMENT
    
 
     Also in connection with the issuance of the Junior Notes, the Company and
the Investor Group entered into a Contingent Share Issuance Agreement (the "CSI
Agreement"). The agreement, as amended and restated pursuant to the
Recapitalization Agreement, provides for the issuance of additional shares of
Class A Common Stock to the purchasers of the Junior Notes to the extent
necessary for such purchasers to earn a specified All-in Return (as defined
below) on their investment. Mr. Hvide and the Hvide Trusts agreed in the
Shareholders Agreement to contribute to the Company a number of shares of Class
B Common Stock equal to the number of shares of Common Stock issued by the
Company pursuant to the CSI Agreement.
 
     Pursuant to the CSI Agreement, the Company issued to the purchasers of the
Junior Notes two series of Common Stock Contingent Share Issuances ("CSIs") that
are convertible into shares of Class A Common Stock on June 10, 1997 (300 days
following completion of the IPO). The number of shares of such stock issuable
with respect to the first series of CSIs is the lesser of (i) that number
necessary to cause the All-in Return to equal 60% and (ii) a number of shares
equal to 9.375% of the outstanding shares of the Company's Common Stock on a
fully-diluted basis, without giving effect to the IPO, the Offering, or the CSI
issuance. The number of shares issuable with respect to the second series of
CSIs is equal to the lesser of (i) that number necessary to cause the All-in
Return to equal 35% and (ii) a number of shares equal to 12.5% of the
outstanding shares of the Company's Common Stock on a fully-diluted basis,
without giving effect to the Offering or the CSI issuance. The value of the
shares of Class A Common Stock issuable upon conversion of the CSIs is based
upon the average market price of the Class A Common Stock during the 30 trading
days preceding June 10, 1997 (the "Valuation Period"). "All-in Return" is
defined as the annual rate of return
 
                                       70
<PAGE>   72
 
earned by the purchasers of the Junior Notes with respect to their aggregate
investment in the Junior Notes, the shares of Common Stock issued to them in
connection with their purchase of the Junior Notes, and the shares of Common
Stock issued to them upon conversion of the CSIs. Accordingly, as calculated
pursuant to such formulas, the maximum number of shares of Class A Common Stock
issuable with respect to the first and second series of CSIs is 237,641 and
316,855 shares, respectively.
 
   
     While it is not possible to predict the future market value of the
Company's Common Stock, barring a dramatic increase in the average market price
of the Class A Common Stock during the Valuation Period, the Company will issue
to the Investor Group following the Valuation Period all 237,641 shares of Class
A Common Stock issuable under the first series of CSIs. With respect to the
shares issuable under the second series of CSIs, if the average market price of
the Class A Common Stock during the Valuation Period is less than $16.63 per
share, the Company will issue to the Investor Group following the Valuation
Period all 316,855 shares of Class A Common Stock issuable under the second
series of CSIs. However, to the extent the average market price of the Class A
Common Stock is greater than $16.63, the number of shares of Class A Common
Stock will be reduced, and no second series CSI shares will be issuable in the
event the average market price of the Class A Common Stock during the Valuation
Period exceeds $19.25 per share. If all 554,496 shares of Class A Common Stock
issuable under the CSIs are issued, the Investor Group's ownership would
increase from 12.5% to 16.2% of the outstanding shares of Common Stock and Mr.
Hvide's ownership would be reduced from 11.9% to 8.2% of the outstanding shares.
The Investor Group has agreed, however, that if following the issuance of the
CSIs, the aggregate votes held by the Investor Group would exceed the votes held
by the Hvide Family, the Investor Group will convert sufficient Class B Common
Stock to Class A Common Stock to allow the Hvide Family to maintain a one-vote
majority over the Investor Group. See " -- Shareholders Agreement -- Share
Adjustment."
    
 
   
REGISTRATION RIGHTS AGREEMENT
    
 
   
     In connection with the Recapitalization Agreement the Company and the
Investor Group entered into a registration rights agreement (the "Registration
Rights Agreement"). Under the Registration Rights Agreement, the Investor Group
has the right to demand that its shares of Common Stock be registered for sale
pursuant to the requirements of the Securities Act, up to three times, subject
to certain deferral rights of the Company. Each of the members of the Investor
Group has the right to request that its shares be included in any registered
underwritten public offering of the Company's Common Stock, subject to certain
cutbacks.
    
 
TRANSFER AGENT
 
     The transfer agent and registrar for the Common Stock is ChaseMellon
Shareholder Services, LLC, New York, New York.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of the Offering, 11,508,375 shares of Class A Common Stock
and 3,419,577 shares of Class B Common Stock will be outstanding, of which the
4,000,000 shares of Class A Common Stock offered hereby (assuming the
Underwriters' over-allotment option is not exercised) and the 7,159,000 shares
sold in the IPO will be transferable without restriction under the Securities
Act, except for shares acquired by "affiliates" of the Company (as defined in
Rule 144 under the Securities Act ("Rule 144")). Of the 1,815,985 shares of
Common Stock to be beneficially owned by the Company's executive officers and
directors following the completion of the Offering, 1,786,818 are currently
eligible for resale under Rule 144, subject to volume and other restrictions
under Rule 144. All of the 1,870,320 shares of Common Stock beneficially owned
by members of the Investor Group are currently eligible for resale under Rule
144, subject to volume and other restrictions under Rule 144.
    
 
     In general, under Rule 144, a person (or persons whose shares are
aggregated) (i) who is not an "affiliate," as that term is defined below, and
whose shares have been outstanding and not owned by an "affiliate" for at least
two years, or (ii) who is an "affiliate" and has beneficially owned his or its
shares for a period of at least two years, is entitled to sell, within any
90-day period, such number of shares that does not
 
                                       71
<PAGE>   73
 
exceed the greater of (i) one percent (1%) of the then-outstanding shares or
(ii) the average weekly trading volume of the then outstanding shares during the
four calendar weeks next preceding each such sale. Resales under Rule 144 are
also subject to certain notice and manner of sale requirements, and the
availability of current public information about the Company. A person (or
persons whose shares are aggregated) who is not deemed an "affiliate" of the
Company at any time during the three months next preceding a sale by such person
(or persons) and who has beneficially owned shares of Common Stock that were not
acquired from the Company or an "affiliate" of the Company within the previous
three years, would be entitled to sell such shares under Rule 144(k) without
regard to volume limitations, manner of sale provisions, notification
requirements, or the availability of current public information concerning the
Company. Affiliates continue to be subject to the restrictions and requirements
of Rule 144. As defined in Rule 144, an "affiliate" of an issuer is a person
that directly, or indirectly through one or more intermediaries, controls, is
controlled by, or is under common control with, such issuer.
 
   
     The Company's executive officers and directors, who collectively are the
beneficial owners of an aggregate of 266,728 shares of Class A Common Stock and
3,419,577 shares of Class B Common Stock in the aggregate (less than 3% of the
Class A Common Stock and 100.0% of the Class B Common Stock upon completion of
the Offering, or 75.4% of the voting power of the Common Stock, assuming the
Underwriters' over-allotment option is not exercised), have executed lock-up
agreements pursuant to which they have agreed not to sell, or otherwise dispose
of, any of their shares of Common Stock for a period of 90 days after the date
of this Prospectus, without the prior written consent of Donaldson, Lufkin &
Jenrette Securities Corporation. The members of the Investor Group, who will
beneficially own 219,850 shares of Class A Common Stock and 1,650,470 shares of
Class B Common Stock in the aggregate upon completion of the Offering (1.9% of
the Class A Common Stock and 48.3% of the Class B Common Stock upon completion
of the Offering, or 36.6% of the voting power of the Common Stock, assuming the
Underwriters' over-allotment option is not exercised) executed lock-up
agreements in connection with the IPO pursuant to which they agreed not to
demand the registration of, offer, sell, contract to sell, or otherwise dispose
of, except to other members of the Investor Group or affiliates thereof, any of
their shares prior to August 7, 1997, without the prior written consent of
Donaldson Lufkin & Jenrette Securities Corporation.
    
 
   
     The Company has granted registration rights to certain stockholders. See
"Description of Capital Stock -- Registration Rights Agreement."
    
 
     The Company has filed a Registration Statement on Form S-8 covering an
aggregate of 1,570,000 shares of Class A Common Stock reserved for issuance
under the Company's Equity Ownership Plan, Employee Stock Purchase Plan, and
Directors Plan. Shares issued under such plans, or issued upon exercise of
options granted under such plans, will be eligible for sale by non-affiliates in
the public market without limitation and by affiliates subject to the provisions
of Rule 144, except for the holding period limitation of Rule 144, subject to
the terms of the lock-up agreements described above.
 
     Sales of substantial amounts of such shares in the public market could
adversely affect the prevailing market price of the Common Stock and could
impair the Company's future ability to raise capital through an offering of its
equity securities.
 
     As part of its business plan, the Company may, from time to time, issue
shares of Common Stock or Preferred Stock to finance future vessel improvements,
acquisitions, and other transactions. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Liquidity and Capital
Resources" and "Business -- Strategy."

     The Underwriters are obligated to purchase all of such shares if any are
purchased. Under certain circumstances, the commitments of non-defaulting
Underwriters may be increased as set forth in the Underwriting Agreement.
 
     The Underwriting Agreement provides that the obligations of the
Underwriters to pay for and accept delivery of the shares of Class A Common
Stock are subject to certain conditions precedent.
 
     The Representatives have advised the Company and the Selling Stockholders
that the Underwriters propose to offer the shares of Class A Common Stock to the
public initially at the public offering price set forth on the cover page of
this Prospectus and to certain dealers at such price less a concession not in
excess of $     per share. The Underwriters may allow, and such dealers may
re-allow, a discount not in excess of $0.10 per share on sale to certain other
dealers. After the initial offering of the Class A Common Stock, the public
offering price, concession, and discount may be changed.
 
   
     The Company and the Hvide Family Trust II have granted the Underwriters an
option, exercisable by the Representatives, to purchase up to 600,000 additional
shares of Class A Common Stock, at the public offering price, less the
underwriting discount. The first 25,000 shares to be purchased pursuant to the
over-allotment option will be purchased from the Hvide Family Trust II and the
balance will be purchased from the Company. Such option, which expires 30 days
after the date of this Prospectus, may be exercised solely to cover
over-allotments. To the extent the Representatives exercise such option, each of
the Underwriters will be obligated, subject to certain conditions, to purchase
approximately the same percentage of the option shares as the number of shares
of Class A Common Stock to be purchased initially by that Underwriter bears to
the total number of shares to be purchased initially by the Underwriters.
    
 
     The Company has agreed to indemnify the several Underwriters against
certain liabilities, including liabilities under the Securities Act, or to
contribute to payments the Underwriters may be required to make in respect
thereof.
 
     In accordance with applicable rules of the National Association of
Securities Dealers, Inc. ("NASD"), no NASD member participating in the
distribution is permitted to confirm sales to accounts over which it

exercises discretionary authority without prior written consent, and,
accordingly, each Underwriter intends to abide by such rules.
 
     In connection with the Offering, the Company's officers and directors and
certain of its stockholders, have agreed that, during a period of 90 days from
the date of this Prospectus, such holders will not, without the prior written
consent of Donaldson, Lufkin & Jenrette Securities Corporation, directly or
indirectly, offer, sell, grant any option with respect to, pledge, hypothecate,
or otherwise dispose of, any shares of Common Stock. In addition, the Company
has agreed that, during a period of 90 days from the date of this Prospectus,
the Company will not, without the prior written consent of the Representatives,

B Common Stock except for (i) shares of Class A Common Stock to be issued in the
Offering, and (ii) shares issued upon the exercise of options to be granted
under the various employee and director benefit plans, as described under
"Management." See "Shares Eligible for Future Sale."

members may engage in passive market making transactions in the Class A Common
Stock on the Nasdaq National Market immediately prior to the commencement of

during a specified prior period, and all passive market making activity must be
discontinued when such limit is reached. Passive market may stabilize the market
price of the Class A Common Stock at a level above that which might otherwise
prevail and, if commenced, may be discontinued at any time.

     The pro forma condensed consolidated statements of operations for the year

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
Board of Directors
  HVIDE MARINE INCORPORATED
 
     We have audited the accompanying consolidated balance sheets of Hvide
Marine Incorporated (f/k/a Hvide Corp.) and subsidiaries as of December 31, 1995
and 1994, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1995. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements 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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Hvide Marine
Incorporated and subsidiaries at December 31, 1995 and 1994, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles.
 
     As explained in Note 1 to the consolidated financial statements, effective
January 1, 1993, the Company changed its method of accounting for drydocking
costs from the accrual method to the deferral method.

                   HVIDE MARINE INCORPORATED AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                           DECEMBER 31, 1994 AND 1995
    (INFORMATION PERTAINING TO SEPTEMBER 30, 1996 AND THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
 
     Organization and Basis of Consolidation.  Hvide Marine Incorporated ("HMI,"
the "Company," and the "Successor") (f/k/a Hvide Corp.) was incorporated in the
state of Florida on September 28, 1994 as the holding company for the former
Hvide Marine Incorporated (f/k/a Hvide Shipping, Incorporated) and its
majority-owned subsidiaries (the "Predecessor Company"). On September 30, 1994,
100% of the Common Stock of the Predecessor Company was exchanged for common
stock of HMI and accounted for in a manner similar to a pooling of interests.
Accordingly, the accompanying consolidated financial statements include the
combined successor/predecessor companies for all periods subsequent to September
30, 1994 and the Predecessor Company for all periods prior to September 30,
1994. All share and per share amounts have been adjusted to give retroactive
effect to the capital structure of HMI. All material intercompany transactions
and balances have been eliminated in the consolidated financial statements.
Investments in limited partnerships and less-than-majority-owned subsidiaries
are accounted for on the equity method.
 
     On August 14, 1996, the Company completed the initial public offering (the
"IPO") of 7,000,000 shares of its Class A Common Stock at $12.00 per share. The
net proceeds to the Company were approximately $74,900,000, after deducting
underwriting commissions and other offering expenses. The net proceeds were used
primarily to repay certain indebtedness that was outstanding prior to the IPO
and for the cash portion of the purchase price of certain acquisitions
consummated simultaneously with and subsequent to the IPO. On September 12,
1996, the underwriters' over-allotment option was exercised in part pursuant to
which an additional 159,000 shares were issued. The net proceeds of
approximately $1,774,000 were used by the Company to repay certain outstanding
indebtedness. In addition, on August 14, 1996, the Company issued 182,000 and
1,188,000 shares of Class A and Class B Common Stock, respectively, in payment
of certain outstanding indebtedness.
 
     Operations.  The principal operations of the Company consist of vessel time
charters, vessel operating agreements and harbor towing. Through its vessel time
charters and operating agreements, the Company serves the energy and chemical
industries in the U.S. domestic trade. The Company's harbor towing operations
principally serve the passenger cruise ship, energy, and chemical industries and
are concentrated in ports located in the southeastern United States.
 
     Revenues.  Revenues from time charters are earned and recognized on a daily
basis. Time charter revenues are adjusted periodically based on changes in
specified price indices and market conditions.
 
     Cash and Cash Equivalents.  The Company considers all highly liquid
investments with a maturity of three months or less when purchased to be cash
equivalents.
 
     Insurance Claims Receivable.  Insurance claims receivable represent costs
incurred in connection with insurable incidents for which the Company expects to
be reimbursed by the insurance carrier(s), subject to applicable deductibles.
Deductible amounts related to covered incidents are expensed in the period of
occurrence of the incident.
 
     Spare Parts and Supplies.  Inventories of spare parts and supplies are
stated at the lower of cost, determined on a basis that approximates the
last-in, first-out method, or market.
 
     Prepaid Expenses.  Prepaid expenses primarily include prepaid vessel
insurance.
 
     Property.  Vessels, improvements and equipment are stated at cost less
accumulated depreciation. Major renewals and improvements are capitalized and
replacements, maintenance and repairs which do not improve or extend the lives
of the assets are expensed. Depreciation is computed on the straight-line method
over the estimated useful lives of the assets. The estimated useful lives of
vessels and improvements other than tankers are 15 to 40 years and the estimated
useful lives of furniture and equipment are 3 to 10 years. Tankers and
 
                                      F-13
<PAGE>   90
 
related improvements are depreciated over estimated useful lives, as determined
by the Oil Pollution Act of 1990 and other factors, ranging from 4 to 24 years.
 
     Vessels under capital leases are amortized over the estimated useful lives
of the vessels. Included in vessels and improvements at December 31, 1994 and
1995 and at September 30, 1996 are vessels under capital leases of approximately
$5,003,000, $5,229,000, and $18,147,000, net of accumulated amortization of
approximately $37,000, $149,000, and $556,000, respectively.
 
     For the years ended December 31, 1993, 1994 and 1995, and the nine months
ended September 30, 1995 and 1996, depreciation and amortization of vessels,
improvements and equipment was approximately $3,020,000, $3,397,000, and
$4,770,000, and $3,590,000, and $4,963,000, respectively.
 
     Accounting for Drydocking Expenses.  Approximately every 30 months, certain
Company vessels are drydocked for major repairs and maintenance which cannot be
performed while the vessels are operating.
 
     Through fiscal 1992, the Company provided currently for the estimated
future costs of drydockings. Effective January 1, 1993, the Company changed its
method of accounting for drydocking costs from the accrual method to the
deferral method. Under the deferral method, the Company capitalizes its
drydocking costs and amortizes them over the period through the next drydocking.
Management believes the deferral method better matches costs with revenues.
Also, the deferral method minimizes any significant changes in estimates
associated with the accrual method. The cumulative effect of this accounting
change for years prior to 1993, which is shown separately in the consolidated
statement of operations for 1993, resulted in a benefit of $1,491,000, or $0.24
per common share.
 
     The following summary reflects net income and net income per common share
for the year ended December 31, 1993 on an historical basis and as if the change
in accounting principle had been retroactively applied:

     At December 31, 1994 and 1995 and at September 30, 1996, deferred costs
include unamortized drydocking of approximately $1,938,000, $2,534,000, and
$7,572,000, respectively.
 
     Deferred Costs.  Deferred costs primarily represent drydocking and
financing costs. Deferred financing costs are amortized over the term of the
related borrowings.
 
     Goodwill.  Goodwill represents the excess of the purchase price over the
fair value of certain assets acquired and is amortized on the straight-line
basis over 20 to 40 years. The carrying value of goodwill is reviewed if facts
and circumstances suggest that it may be impaired. If this review indicates that
goodwill will not be recoverable, as determined based on the estimated
undiscounted cash flows of the assets acquired over the remaining amortization
period, the carrying value will be adjusted accordingly. At December 31, 1994
and 1995 and at September 30, 1996, accumulated amortization of goodwill was
approximately $1,184,000, $1,689,000, and $2,067,000, respectively.
 
     Income Taxes.  HMI files a consolidated tax return with all corporate
subsidiaries other than Seabulk Ocean Systems Holdings, Inc. and Seabulk Ocean
Systems Corporation, which file a separate consolidated income tax return. Each
partnership subsidiary files a separate partnership tax return.
 
     The Financial Accounting Standards Board ("FASB") issued Statement No. 109,
"Accounting for Income Taxes," which requires the liability method of accounting
for income taxes. Under the liability method, deferred income tax assets and
liabilities are determined based on differences between financial reporting and
tax bases of assets and liabilities, and are measured using the enacted tax
rates and laws in effect when the differences are expected to reverse. Under
FASB Statement No. 109, the effect on deferred tax
 
                                      F-14
<PAGE>   91
 
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date. The Company adopted FASB Statement No.
109 in 1993 and applied its provisions retroactively.
 
     Recent Accounting Change.  In March 1995, the FASB issued Statement No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of," which requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted cash flows estimated to be generated by those assets are
less than the assets' carrying amount. Statement No. 121 also addresses the
accounting for long-lived assets that are expected to be disposed of. The
Company adopted Statement No. 121 in the first quarter of 1996 and the effect of
adoption was not material.
 
     In October 1995, the FASB issued Statement No. 123, "Accounting for
Stock-Based Compensation," for fiscal years beginning after December 15, 1995.
This Statement establishes a fair-value based method of accounting for stock
compensation plans with employees and others. The Company continues to account
for its stock-based compensation plans under Accounting Principles Board Opinion
No. 25 "Accounting for Stock Issued to Employees", as permitted by Statement No.
123 and will present the pro forma disclosures required under Statement No. 123
in fiscal year 1997 with no impact to the Company's results of operations.
 
     Earnings (Loss) per Common Share.  Earnings (loss) per common share is
calculated based on the weighted average number of common shares and dilutive
common stock equivalents outstanding during the period. Common stock equivalents
result from convertible preferred stock outstanding in 1993 and 1994 and
outstanding stock options at September 30, 1996. Earnings (loss) per common
share-assuming full dilution includes the if-converted dilutive effect of a
portion of the convertible Junior Note through conversion in August 1996 (see
Note 3) and the incremental dilutive effect of outstanding common stock options
at September 30, 1996.
 
     Concentrations of Credit Risk.  Financial instruments which potentially
subject the Company to concentrations of credit risk consist principally of cash
and cash equivalents in banks, trade accounts receivable and insurance claims
receivable. The credit risk associated with cash and cash equivalents in banks
is considered low due to the credit quality of the financial institutions. The
Company performs ongoing credit evaluations of its trade customers and generally
does not require collateral. The credit risk associated with insurance claims
receivable is considered low due to the credit quality and funded status of the
insurance pools that the Company participates in.
 
     Estimates.  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
     Reclassifications.  Certain amounts from prior periods' consolidated
financial statements have been reclassified to conform with the current period's
presentation.
 
     Interim Financial Information (Unaudited).  The unaudited consolidated
interim financial statements for the nine-month periods ended September 30, 1995
and 1996 and as of September 30, 1996 have been prepared on a basis consistent
with that of the Company's audited consolidated financial statements as of and
for the three-year period ended December 31, 1995. In the opinion of management,
all adjustments, consisting of normal recurring accruals, necessary for a fair
presentation of the unaudited information shown have been included. The results
of operations for such interim periods are not necessarily indicative of the
results expected for the full year ending December 31, 1996.
 
2. CAPITAL CONSTRUCTION FUNDS
 
     Pursuant to a Dual Use Agreement between Seabulk Tankers, Ltd. ("STL") and
the United States of America ("U.S."), the Capital Construction Funds maintained
by STL is collateral to the U.S., which amounts were $33,000 and $36,000 at
December 31, 1994 and 1995, respectively.

     On September 28, 1994, the Company entered into an agreement, as amended on
May 15, 1995, March 26, 1996 and June 21, 1996, for a credit facility (the
"Credit Facility") with its principal banks.
 
   
     The Credit Facility provides for a working capital credit line of
$7,500,000 through January 15, 2001 (the "Line") and a stand-by letter of credit
(the "Letter of Credit") of $5,600,000. Borrowings under the Line bear interest
at the prime rate or LIBOR, at the option of the Company, plus an applicable
margin based upon the Company's compliance with certain financial covenants
(approximately 8.9% and 7.9% at December 31, 1995 and September 30, 1996,
respectively), and are subject to an annual commitment fee of 0.50% of the
unused portion of the Line. Borrowings outstanding under the Line totaled
$7,500,000 and $5,500,000 at December 31, 1995 and September 30, 1996, of which
$5,500,000 is currently due. The Letter of Credit is collateral for a surety
bond to fund any final award relating to the shipyard's claims discussed in Note
5. Additionally, the Credit Facility provides for a letter of credit in an
amount equal to the greater of amounts available to be drawn under the Line or
$4,000,000. Amounts drawn under either letter of credit are due on demand or the
ultimate maturity date of January 15, 2001. There were no amounts outstanding
under the letters of credit at December 31, 1995 or September 30, 1996.
    
 
   
     The Credit Facility provided for a term loan (the "Term Loan") in the
original principal amount of $50,000,000. The Term Loan is payable in quarterly
principal and interest payments beginning January 15, 1995. Borrowings under the
Term Loan bear interest at the prime rate or LIBOR, at the option of the
Company, plus an applicable margin based upon the Company's compliance with
certain financial covenants. At December 31, 1995 and September 30, 1996, the
Term Loan was accruing interest at LIBOR +3.0% and LIBOR +2.5%, respectively
(approximately 8.9% and 8.2%, respectively).
    
 
   
     The Credit Facility provided for automatic increases under the Line and
Term Loan and certain additional borrowings upon the successful completion of a
public offering. Accordingly, upon consummation of the IPO on August 14, 1996,
the Line increased to $10,000,000, the Term Loan increased to $60,500,000 and an
acquisition line of credit (the "Acquisition Line") of $19,900,000 became
available. On August 14, 1996, $4,200,000 was drawn under the Acquisition Line
which bears interest at LIBOR +2.5% (8.0% at September 30, 1996) and is due in
January, 2001.
    
 
     The collateral for the Company's indebtedness under the Credit Facility
includes all Company-owned vessels, its partnership interests in STL and Seabulk
Transmarine Partnership, Ltd., spare parts, fuel and supplies, and eligible
accounts receivable.
 
     On September 30, 1994, and as amended on May 24, 1995, the Company issued a
$25,000,000 senior subordinated note (the "Senior Note"). The Senior Note bears
interest at 12%, payable semi-annually on March 31 and September 30. The
principal portion of the Senior Note is payable in equal annual installments
 
                                      F-16
<PAGE>   93
 
on September 30, 2003 and 2004. The Company received proceeds of approximately
$23,072,000, net of a discount of $1,928,000 ($1,904,000, $1,800,000 and
$789,000 at December 31, 1994 and 1995 and September 30, 1996, respectively)
which is being amortized as interest expense over the term of the Senior Note.
On August 14, 1996 and September 12, 1996, the Company repaid $13,490,000, and
$1,700,000, respectively, of the principal balance of the Senior Note with a
portion of the proceeds from the IPO and the exercise of the underwriters'
related over-allotment option. Repayment of the Senior Note is subordinated to
the claims of the Company's principal banks for amounts outstanding under the
Credit Facility.
 
     The terms of the Credit Facility and Senior Note prohibit the Company or
any of its wholly owned subsidiaries from paying dividends on any class of
common stock and restrict, among other things, the Company's ability to enter
into new commitments or borrowings over specified amounts and dispose of assets
outside the ordinary course of business. In addition, the Company is required to
maintain a minimum level of tangible net worth, as defined, and to prepay
amounts outstanding under the Credit Facility to the extent of 50% of excess
cash flow, as defined.
 
     On September 30, 1994, HMI issued a $25,000,000 junior subordinated note
(the "Junior Note"). The Junior Note bears interest at 8%, compounded quarterly.
The principal sum and all accrued and unpaid interest ($2,607,000 at December
31, 1995) was payable on the earlier of the IPO or September 30, 2014. The
Company received proceeds of approximately $17,508,000, net of a discount of
$7,492,000 ($7,464,000 and $7,367,000 at December 31, 1994 and 1995,
respectively) which was being amortized as interest expense over the term of the
Junior Note. Repayment of the Junior Note was subordinated to the claims of the
Company's principal banks for amounts outstanding under the Credit Facility and
to the claims of the note holders for amounts outstanding under the Senior Note.
In August 1996, the principal sum and all accrued and unpaid interest was repaid
with $15,115,000 of the proceeds from the IPO and the issuance of 1,244,002
shares of Common Stock.
 
     In connection with the acquisition of the minority interest in STL in 1994
(see Note 6), the Company issued a note payable of approximately $3,039,000.
Interest on the note is payable quarterly at Prime +2%, limited to 10% (10% at
December 31, 1995), and the principal portion of the note is due in equal annual
installments through 1999 ($2,431,000 outstanding at December 31, 1995). On
August 14, 1996, the note was repaid with a portion of the proceeds from the
IPO.
 
   
     In connection with the acquisition of the outstanding limited partnership
interests in Hvide Chartering, Ltd. ("HCL") and Hvide Offshore Services, Ltd.
("HOS") in 1994 (see Note 6), the Company issued notes payable of approximately
$2,149,000. Approximately $1,302,000 of these notes were issued to certain
officers and employees of the Company and are recorded as notes payable to
related parties in the accompanying consolidated balance sheets. Interest on the
notes is payable quarterly at 12% and the notes are due in 2004. On August 14,
1996, approximately $678,000 of the notes payable to related parties, was repaid
with $370,000 of the proceeds from the IPO and the issuance of 25,667 shares of
Common Stock.
    
 
   
     In connection with redemption of the outstanding preferred stock of the
Predecessor Company in 1994 (see Note 9), the Company issued notes payable
totaling approximately $3,561,000 to the former stockholder. Interest on the
notes is payable quarterly at the greater of 12% or Prime +3% (12% at December
31, 1995 and September 30, 1996). The principal portion of the notes is due in
the year 2000. Repayment of these notes is subordinated to the claims of the
Company's principal banks for amounts outstanding under the Credit Facility. On
August 14, 1996, approximately $1,548,000 was repaid with a portion of the
proceeds from the IPO.
    
 
     In connection with the acquisition of seven crew vessels in 1995 (see Note
12), the Company issued a $3,000,000 note payable. The note bears interest at 8%
and provides for quarterly payments of principal and interest through the year
2000 ($2,550,000 outstanding at December 31, 1995). The note is secured by first
preferred mortgages on four of the acquired vessels. The note payable was repaid
in February 1996.
 
     In connection with the acquisition of the outstanding common stock of its
previously unconsolidated 50%-owned affiliate Ocean Specialty Tankers
Corporation ("OSTC"), on August 14, 1996, the Company assumed OSTC's obligations
under a $2,000,000 revolving line of credit secured by the outstanding accounts
 
                                      F-17
<PAGE>   94
 
receivables generated by three chemical carriers. The revolving line of credit
bears interest monthly at 7.0% of the outstanding amount. At September 30, 1996,
$1,933,000 was outstanding under the line of credit which is due currently.
 
     On August 14, 1996, the Company assumed approximately $34,650,000 of Title
XI Debt in connection with the acquisitions of certain vessels (see note 12).
The Title XI Debt is collateralized by first preferred mortgages on certain
vessels and bears interest at rates ranging from 5.4% to 10.1%. The debt is due
in semiannual principal and interest payments through December 1, 2006.
 
     The aggregate annual future payments due on debt and notes payable are as
follows (in thousands):

5. COMMITMENTS AND CONTINGENCIES
 
     A significant portion of the Company's operations consists of charters of
ocean-going vessels. The Seabulk Challenger and Seabulk Magnachem are bareboat
chartered for periods extending through the years 1999 and 2002, respectively.
Charter hire expense on these vessels was approximately $3,400,000, $3,100,000
and $3,153,000, and $2,355,000 and $2,388,000, for the years ended December 31,
1993, 1994 and 1995, and the nine months ended September 30, 1995 and 1996,
respectively. The Company's tractor tug Broward is
 
                                      F-18
<PAGE>   95
 
bareboat chartered, through the year 2010. Charter hire expense on this vessel
was approximately $217,000 and $488,000 for the year ended December 31, 1995 and
the nine months ended September 30, 1996, respectively. The aggregate annual
future payments due under these charter agreements at December 31, 1995 for the
next five years are as follows (in thousands):

     The Company is party to a lease agreement, as amended, of its office
facilities with a remaining period of 14 years. The estimated remaining
commitment under this lease at December 31, 1995 was $7,450,000 with
approximately $532,000 payable in each of the next five years.
 
   
     Rent expense for the years ended December 31, 1993, 1994 and 1995, and for
the nine months ended September 30, 1995 and 1996, was approximately $341,000,
$467,000 and $666,000 and $545,000 and $524,000, respectively.
    
 
     In 1990, the Company withheld approximately $2,400,000 from a shipyard
relating to delays and other problems encountered in the construction of a
vessel. In 1993, the shipyard filed a claim to recover approximately $8,500,000
for costs allegedly due the shipyard, and the Company asserted a counterclaim
for approximately $5,600,000 against the shipyard. In addition, the shipyard is
seeking $10,000,000 of punitive damages. Management believes the shipyard's
claim amounts are unsubstantiated and that recoveries upon the Company's
counterclaim, together with insurance coverage, will exceed amounts, if any,
which may be awarded to the shipyard. Management believes that the additional
costs incurred to complete the construction of the vessel exceeded the amounts
withheld (settlement of construction costs, if any, would generally be
capitalized and depreciated over future periods); however, the Company is unable
to predict the final outcome of this matter.
 
     In November 1989, STL formed an 88%-owned subsidiary, Seabulk Offshore,
Ltd. ("SOL"), which acquired eight offshore supply vessels for approximately
$13,510,000. In December 1990, STL and Hvide Marine Transport, Incorporated (a
wholly-owned subsidiary of HMI) purchased the remaining 12% interest in SOL from
the limited partner ("U.S. Offshore") for $825,000. Additionally, SOL agreed to
pay U.S. Offshore an amount equal to 5% of gross revenues from the operation of
the vessels for a period not to exceed a maximum of 40 months (December 1, 1990
through March 31, 1994) and in a total amount not to exceed $1,300,000,
whichever occurred first. Approximately $769,000 has been paid to U.S. Offshore
under this agreement. U.S. Offshore has filed a claim against SOL related to the
amount due under the agreement. SOL is vigorously defending this claim and
believes that it will ultimately prevail; however, the Company is unable to
predict the final outcome of this matter.
 
     On August 6, 1992, a wholly-owned subsidiary, Seabulk Transmarine II, Inc.
acquired a 49% interest in a joint venture which charters two offshore supply
vessels from SOL for a period of six years. At the end of the charter period,
the joint venture shall have the option to purchase each of the vessels at an
agreed-upon purchase price of $300,000.
 
     On September 30, 1994, the Company acquired Sun State Marine Services, Inc.
("SSMS"). The acquisition agreement provides the sellers contingent payments for
a period of five years from the date of the agreement. The contingent amount
payable each year is 30% of the amount by which net income pertaining to the
acquired operations for that year, as defined, exceeds $1,800,000. The aggregate
total of the additional consideration is limited to $3,000,000 over the term of
the agreement. Such contingent payments, when incurred, will be recorded as
additional cost of the acquisition. During the year ended December 31, 1995,
contingent payments made related to 1994 amounted to approximately $36,000.
There were no contingent amounts due related to the acquired operations for the
year ended December 31, 1995.

     The Company has guaranteed 50% of the outstanding line of credit borrowings
of OSTC, up to a maximum of $2,000,000. Total borrowings outstanding under the
line of credit subject to the guarantee were approximately $1,600,000 at
December 31, 1995.
 
     At December 31, 1995, the Company was party to an agreement, as amended on
January 31, 1996 and March 28, 1996, for the purchase of the remaining 50% of
the outstanding common stock of OSTC, pursuant to which the Company is to
acquire three chemical tankers. On August 14, 1996, the Company consummated the
agreement (See Note 12).
 
     At December 31, 1995, Hvide Partners, L.P. ("HPLP"), an affiliated entity
in which the Company participates as the sole general partner, was party,
through its five 75%-owned limited liability companies Hvide Van Ommeren Tankers
I-V LLC ("HVOT I-V"), to contracts for the construction of five double-hull
petroleum product carriers. Pursuant to its general and indirect limited
partnership interests in HPLP, the Company is required to make capital
contributions to HPLP in 1996 totaling approximately $1,000,000. The Company was
also party to an agreement at December 31, 1995 to provide technical services
and support related to the operations of HVOT I-V. Pursuant to this agreement
and commencing in 1997, the Company is to be paid an annual fee of $295,000,
subject to future escalation equal to increases, if any, in the CPI.
 
   
     In November and December 1996, the Company entered into agreements to
purchase 12 vessels for an aggregate amount of approximately $36,275,000.
Deposits aggregating $2,739,000 have been paid on these vessels.
    
 
     In November 1996, the Company entered into an agreement to bareboat charter
two tugs for a one year period.
 
6. RELATED PARTY TRANSACTIONS
 
     In 1994, the Company acquired outstanding limited partnership interests of
HCL, a limited partnership in which the Company owned a 33 1/3% interest as
general partner, from certain officers and employees of the Company for cash and
notes payable of approximately $668,000 and $1,089,000, respectively.
 
     In 1994, the Company acquired the outstanding limited partnership interests
of HOS from certain officers and employees of the Company for cash and notes
payable of approximately $607,000 and $1,060,000, respectively. Additionally,
the company assumed HOS's outstanding capital lease obligations and certain
other liabilities.
 
     The purchase price of the vessels and other net assets acquired in the
acquisition of the limited partnership interests of HCL and HOS was
approximately $1,974,000 in excess of their historical net book value.
Accordingly, such amounts were deemed special distributions to the related
parties and recorded as a reduction of paid-in capital.
 
     In 1994, the Company acquired the outstanding minority interest in STL for
cash and notes payable of approximately $1,302,000 and $3,039,000, respectively.
 
     Maritime Transport Development Corp., which is owned by the former Chairman
of the Company, receives a commission equal to 1.25% of charter hire
(approximately $210,000, $190,000, and $210,000 for the years ended December 31,
1993, 1994, and 1995, respectively) received by the Company for the Seabulk
Challenger and the Seabulk Magnachem as payment for development and engineering
services and marketing services related to the design of these vessels.
 
7. EMPLOYEE BENEFIT PLANS
 
     The Company sponsors a Section 401(k) retirement plan covering
substantially all employees. Expense under this plan for the years ended
December 31, 1993, 1994 and 1995, and for the nine months ended September 30,
1995 and 1996, was approximately $724,000, $834,000 and $1,047,000, and $796,000
and $998,000, respectively. Contributions under the plan are determined on the
basis of employee compensation.

8. STOCK OPTIONS
 
     On August 12, 1996, the Company granted options to purchase 35,000 and
771,000 shares of Class A Common Stock to members of the Company's board of
directors and certain executives, respectively. The exercise price of the
options was equal to the fair market value of the underlying common stock of
that date. The directors' options are 100% vested and all other options vest
ratably over a four-year period. For the period from August 13, 1996 to
September 30, 1996, there were no options granted, exercised or cancelled.

Additionally, 182,000 and 1,188,000 shares of the Company's Class A and Class B
Common Stock were, respectively, issued in repayment of a portion of the Junior
Notes and other certain outstanding indebtedness.
 
     On May 10, 1996, the Company's Board of Directors authorized a 1.5843-for-1
split of its common stock, and an increase of the number of authorized shares of
its Class A, Class B, and Class C Common Stock to 100,000,000, 5,000,000, and
2,500,000, respectively. All share and per share data in the accompanying
financial statements have been restated to reflect the stock split.
Contemporaneous with the IPO, the Company's Board of Directors authorized the
retirement of the Company's Class C Common Stock.
 
     On September 28, 1994, all the stock of the Predecessor Company was
exchanged for shares of the Company's stock (see Note 1). The fair value of the
Predecessor Company's common stock and the Company's common stock were
equivalent.
 
     On September 29, 1994, all of the outstanding shares of Class A and Class B
Preferred Stock of the Predecessor Company were repurchased from the shareholder
for cash of $2,374,000, notes of $3,561,000 and certain agreements providing for
future payments over a specified term. The present value of the agreements
providing for future payments has been recorded in other liabilities in the
accompanying consolidated balance sheets and total approximately $1,350,000 and
$1,282,000 at December 31, 1994 and 1995, respectively.
 
     Each share of the Company's Class A Common Stock is entitled to one vote
per share and each share of Class B Common Stock is entitled to ten votes per
share. Shares of Class C Common Stock are nonvoting. The holders of Class B
Common Stock are entitled to convert, at the holder's election and at any time,
such shares into shares of Class A Common Stock or Class C Common Stock at the
rate of one share of Class B Common Stock for one share of Class A Common Stock
or Class C Common Stock. The holders of Class C Common Stock are entitled to
convert, at the holder's election and subject to certain restrictions, such
shares into shares of Class A Common Stock at the rate of one share of Class C
Common Stock for one share of Class A Common Stock.
 
     In connection with the issuance of the Junior Note, the Company issued to
the note holders 765,733 shares of its Class B and Class C Common Stock and
Common Stock Contingent Share Issuances ("CSIs") to purchase a maximum of
554,495 additional shares of its common stock. The Junior Note, shares of Class
A and Class C Common Stock and the CSIs were recorded based upon their estimated
fair values at the date of issuance. The CSIs are generally exercisable, at a
price equal to the par value of the underlying shares, at the earlier of a
qualified initial public offering of the Company's common stock, or September
30, 1998. The maximum amount of CSIs that may be exercised is based upon the
note holders return on their investment in the Company.
 
     Simultaneously with the issuance of the CSIs, the Company entered into an
agreement with its Chairman and principal stockholder and certain trusts whereby
the principal stockholder and the trusts agreed to contribute pro rata a like
amount of shares of common stock to the Company concurrently with the issuance
of shares pursuant to the CSIs. Accordingly, issuance of shares pursuant to the
CSIs will not effect the Company's financial position or results of operations.

13. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following methods and assumptions were used to estimate the fair value
of financial instruments included in the following categories:
 
          Cash and cash equivalents and accounts receivable.  The carrying
     amounts reported in the balance sheets approximates fair value.
 
          Credit Facility, Mortgage note and Other.  Amounts outstanding under
     the Company's Credit Facility, as amended, bear interest at variable rates
     that periodically adjust to reflect changes in overall market rates and
     approximate fair value. Amounts outstanding in 1994 under the mortgage note
     and other amounts approximate fair value due to their short-term nature.
 
          Senior and Junior Notes.  Amounts outstanding under the Senior and
     Junior Notes bear interest at 12% and 8%, respectively. The fair value of
     the Senior and Junior Notes at December 31, 1995 was estimated to be $23.5
     million and $16.5 million, respectively, using a discounted cash flow
     analysis at estimated market rates.
 
          Notes Payable.  The carrying amount reported in the balance sheets
     approximates fair value using a discounted cash flow analysis at estimated
     market rates.

LONG-TERM DEBT
 
     On September 30, 1994, the Company issued the Junior Note (see Note 3).
 
     The Company serves as co-guarantor of amounts under the Credit Facility and
Senior Note (see Note 3). Repayment of the Junior Note is subordinated to the
claims for amounts outstanding under the Credit Facility and the Senior Note.
 
DIVIDENDS FROM SUBSIDIARIES
 
     No cash dividends have been paid to the Parent Company since inception as
the Company's Credit Facility prohibits the payment of dividends or other
distributions on any class of capital stock of the Company or its wholly-owned
subsidiaries.
 
STATEMENT OF CASH FLOWS
 
     The statement of cash flows has been omitted as the Parent Company does not
maintain cash balances. 

15. EXTRAORDINARY ITEM
 
     On August 14, 1996, the Company utilized common stock and a portion of the
proceeds from the IPO to repay $25,000,000 and $15,190,000 of the Junior and

                          INDEPENDENT AUDITORS' REPORT
 
To the Boards of Directors and Stockholder of OMICHEM TRANSPORT, INC.,
OMI CLOVER TRANSPORT, INC., and OMI HUDSON TRANSPORT, INC.:
 
     We have audited the accompanying combined balance sheets of the OMI
Chemical Carrier Group as of December 31, 1994 and 1995 and the related combined
statements of operations and deficit and of cash flows for each of the three
years in the period ended December 31, 1995. The combined financial statements
include the accounts of Omichem Transport, Inc., OMI Clover Transport, Inc., and
OMI Hudson Transport, Inc. which are wholly owned subsidiaries of OMI Corp.
These financial statements are the responsibility of the companies' management.
Our responsibility is to express an opinion on these financial statements 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, such financial statements present fairly, in all material
respects, the combined financial position of the OMI Chemical Carrier Group at
December 31, 1994 and 1995 and the combined results of their operations and
their combined cash flows for each of the three years in the period ended
December 31, 1995 in conformity with generally accepted accounting principles.

                           OMI CHEMICAL CARRIER GROUP
 
                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
                  FOR THE THREE YEARS ENDED DECEMBER 31, 1995
        AND (UNAUDITED) FOR THE SIX MONTHS ENDED JUNE 30, 1995 AND 1996
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Basis of Combined Statements.  The combined financial statements for the
OMI Chemical Carrier Group (the "Group" or "Companies") include the financial
statements of Omichem Transport, Inc., OMI Clover Transport, Inc., and OMI
Hudson Transport, Inc. which are wholly owned subsidiaries of OMI Corp. ("OMI").
The three companies each own a vessel (OMI Star, OMI Hudson and OMI Dynachem,
respectively) which is time chartered to a joint venture, Ocean Specialty
Tankers Corporation ("OSTC"), owned by OMI and Seabulk Ocean Systems Corporation
("SOSC"), a subsidiary of Hvide Marine Incorporated ("Hvide") (see Note 3). OSTC
contracts with customers for ocean shipping of liquid chemicals.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
     Since inception, the Companies have incurred cumulative losses aggregating
over $99,000,000 at June 30, 1996. The Companies have been able to sustain their
ongoing operations because of OMI's commitment to provide funding for working
capital and other purposes. These financial statements have been prepared on the
assumption that OMI will continue to provide required funding in the future.
 
     In October 1995, OMI entered into an agreement with Hvide for the sale of
the OMI Star, OMI Hudson and OMI Dynachem and its interest in OSTC for
approximately $64,650,000, $30,000,000 in cash and the assumption of all
outstanding indebtedness relating to the vessels ($34,650,000 at June 30, 1996).
The agreement was amended April 30, 1996 to swap the OMI Dynachem for a
replacement vessel to be identified at a later date. Cash of $12,775,000 (of the
$30,000,000) was transferred to an escrow account at delivery until such vessel
is identified and delivered. The sale of these three vessels and the interest in
OSTC is contingent upon Hvide successfully completing its initial public
offering of common stock in 1996, which was accomplished on August 14, 1996.
 
     Unaudited Financial Statements.  In the opinion of management, the
unaudited combined financial statements reflect the adjustments (comprising only
normal recurring accruals) necessary for a fair presentation of financial
position at June 30, 1996 and results of operations and cash flows for the six
months ended June 30, 1995 and 1996.
 
     Accounting Estimates.  The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
     Operating Revenues and Expenses.  Voyage revenues are earned and recognized
on a daily basis and are subject to adjustments based on the operating results
of OSTC.
 
     Special survey and drydock expenses are accrued and charged to operating
expense over the survey cycle, which generally is a two- to three-year period.
The accruals of such expenses are based on management's best estimates of future
cost and the expected length of the survey cycle. However, the ultimate
liability may be more or less than such estimates.

     Vessels and Improvements.  Vessels are recorded at cost. Depreciation for
financial reporting purposes is provided principally on the straight-line method
based on the estimated useful lives of the vessels up to the vessels' estimated
salvage value. The useful lives of the vessels are 25 and 30 years. Salvage
value is based upon a vessel's light weight tonnage multiplied by a scrap rate.
 
     Improvements on leased vessels are amortized on the straight-line method
over the lives of the leases.
 
     In the event that facts and circumstances indicate that the carrying amount
of a vessel may be impaired, an evaluation of recoverability is performed. If an
evaluation is required, the estimated future undiscounted cash flows associated
with the vessel are compared to the vessel's carrying value to determine if a
write-down to fair value or discounted cash flow is required (see Note 5).
 
     The Companies adopted Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of" effective January 1, 1995. Adoption of this statement did not
have a material effect on the Companies' combined financial position or results
of operations.
 
     Income Taxes.  The Companies are included in a consolidated Federal income
tax return filed by OMI which includes all eligible subsidiary Companies. The
accompanying financial statements include for each subsidiary in the Group a
cost or benefit for Federal income taxes based on the related separate taxable
income of each subsidiary. Deferred income taxes are recorded under the
provisions of Statement of Financial Accounting Standards No. 109, "Accounting
for Income Taxes."
 
     Retirement Plans.  The Companies comprising the Group make contributions to
union sponsored multi-employer pension plans covering seagoing personnel.
Contributions to these plans amounted to approximately $218,000, $276,000, and
$262,000 for the years ended December 31, 1993, 1994 and 1995 and $130,000 and
$116,000 for the six months ended June 30, 1995 and 1996, respectively. If these
Companies were to withdraw from the plans or the plans were to terminate, the
Companies would be liable for a portion of any unfunded plan benefits that might
exist. The Group has been advised by the trustees of such plans that it has no
withdrawal liability as of December 31, 1995.
 
     Cash Flows.  During the years ended December 31, 1993, 1994 and 1995, the
Group paid interest of $2,504,000, $1,932,000, and $1,475,000, respectively.
During the six months ended June 30, 1995 and 1996 the Group paid interest of
$884,000 and $565,000, respectively.

     The bonds are collateralized by a mortgage on the OMI Dynachem and OMI
Hudson and are guaranteed as to principal and interest by the U.S. Government
under the Title XI Program. At June 30, 1996, the vessels (net book values
aggregating $56,978,000) and investments of $9,857,000 held by OMI Corp. in its
Capital Construction and other restricted funds have been pledged as collateral
for the long-term debt issues. The security arrangement restricts OMI Hudson
Transport, Inc. and OMI Clover Transport, Inc. ("OMI Clover") from, among other
things, the withdrawal of capital, the payment of common stock dividends and the
extending of loans to affiliated parties.

     Subsequent to December 31, 1995, aggregate annual maturities of the bonds
during each of the next five years 1996 through 2000 were $2,525,000. Subsequent
to June 30, 1996, aggregate maturities for a twelve month period on such bonds
in the next five years through 2001 are $4,815,000.
 
     The fair value of the bonds is estimated based on current rates available
for similar issues.
 
3. OPERATING LEASES
 
     Total rent expense, which relates to two vessels, amounted to $10,730,000,
$10,805,000 and $7,557,000 for the years ended December 31, 1993, 1994 and 1995,
respectively. Rent expense for the six months ended June 30, 1995 and 1996 was
$4,371,000 and $755,000, respectively.
 
     OMI Clover has operated the vessel OMI Hudson under a long-term operating
lease requiring semi-annual payments through December 2006. In October 1995, OMI
Clover entered into an agreement with the owner/lessor of the OMI Hudson to
terminate the operating lease for $25,000,000 and subsequently purchase the
vessel for $30,000,000. The estimated loss on lease termination of $3,297,000
was reported as a separate item in the 1995 Combined Statement of Operations and
Deficit. In February 1996, OMI Clover terminated the operating lease on the
vessel for $22,000,000 cash and the issuance of a $3,000,000 Convertible Note by
OMI. In March 1996, OMI Clover purchased the vessel for cash of $9,300,000
($10,430,000 less reimbursement of a portion of the lease payment of $1,130,000
in accordance with the agreement) and assumption of debt of $19,570,000 (see
Note 2). The $31,300,000 cash paid by OMI on behalf of OMI Clover and the
$3,000,000 Convertible Note issued by OMI aggregating $34,300,000 to terminate
the lease and purchase the vessel was recorded as a capital contribution to OMI
Clover.
 
     In 1992, Omichem Transport, Inc. ("Omichem") entered into a sale/leaseback
transaction for the OMI Star. Omichem received $11,500,000 in cash, of which
$3,500,000 was used to pay the mortgage on the vessel, a $2,000,000 secured note
receivable paid December 1994 and a six year lease. The gain on the transaction
of approximately $2,001,000 was deferred and amortized over the life of the
lease until June 29, 1995 when Omichem repurchased the OMI Star for $9,623,000.
The funds to purchase the OMI Star were in the form of a long-term advance from
OMI at a variable rate based on the London Interbank Offering Rate.
 
     The three vessels operated by the Group are time chartered to OSTC, a joint
venture between OMI and SOSC. The balances included in the financial statements
due from OSTC represent charter hire receivables.
 
     As of December 31, 1995 the Companies have time charter agreements with
OSTC for initial terms ending May 31, 2000, with extension options after that
date. The vessels are under charter for "base" hire rates dependent upon the
performance of the vessels.

     On August 2, 1993, Congress passed the Omnibus Budget Reconciliation Act of
1993 (the "Act"). The major component of the Act affecting the Group was the
retroactive increase in the marginal corporate tax rate from 34 percent to 35
percent, increasing the 1993 deferred income taxes of the Group by $438,000 to
comply with the provisions of the Act.
 
5. IMPAIRMENT AND PROVISION FOR LOSS ON VESSEL LEASE OBLIGATION
 
     As part of the periodic review of the recoverability of the investment in
vessels, in 1994 management determined that the carrying value of the OMI
Dynachem exceeded the undiscounted forecasted future net cash flows from its
operations. This indicated that an impairment loss for this vessel should be
recognized. This loss was measured by the excess of the carrying value of the
vessel over its estimated fair value which was based on values provided by two
shipbrokers. The carrying value was reduced by $14,798,000, which is reported as
a separate item in the 1994 Combined Statement of Operations and Deficit.
 
     As part of this periodic review, it also was determined that a similar loss
should be recognized for the forecasted loss from operations of the OMI Hudson
which is chartered-in on an operating lease through 2006. The amount of the loss
was estimated based on forecasted undiscounted cash flows, excluding from rent
expense an amount representative of the interest component of the lease
agreement, through the lease expiration date. This loss, estimated as
$19,800,000, is also reported as a separate item in the 1994 Combined Statement
of Operations and Deficit.
 
6. TRANSACTIONS WITH PARENT
 
     Due from (to) Parent represents tax benefits currently due from OMI reduced
by non-interest bearing advances from OMI to fund the Group's operations. OMI
maintains a centralized cash management system whereby it accepts and deposits
all cash receipts on behalf of its subsidiaries and pays all costs, expenses and
other obligations of such subsidiaries. These disbursements primarily represent
vessel and voyage expenses, lease payments, interest expense and required
payments of long-term debt. The average balances due from (to) OMI (based on
individual monthly balances outstanding) are as follows:

     The method used allocates fixed annual amounts of costs on a per vessel
basis for financial accounting and vessel management activities and allocates
costs for general corporate activities based on 1.25 percent of revenues earned
by each vessel. Management of OMI believes that this allocation method is
reasonable.
 
7. CONTINGENT LIABILITIES
 
     Companies in the Group are defendants in various legal actions from
shipping operations. Such actions are covered by insurance or, in the opinion of
management after review with counsel, are of such a nature that the ultimate
liability, if any, would not have a material adverse effect on the combined
financial statements.

Partners of
  INDIAN SEAL PARTNERS, LTD.,
  BAFFIN SEAL PARTNERS, LTD.,
  BALTIC SEAL PARTNERS, LTD.,
  BENGAL SEAL PARTNERS, LTD., AND
  ROSS SEAL PARTNERS, LTD.
 
     We have audited the accompanying Combined Statements of Vessel Operations
of Indian Seal Partners, Ltd., Baffin Seal Partners, Ltd., Baltic Seal Partners,
Ltd., Bengal Seal Partners, Ltd., and Ross Seal Partners, Ltd. (collectively
"the Seal Partners") for the years ended December 31, 1995, 1994 and 1993. These
financial statements are the responsibility of the management of the Seal
Partners. Our responsibility is to express an opinion on these financial
statements 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.
 
     As described in Note 1, the combined financial statements referred to above
have been prepared in accordance with the Asset Purchase Agreement between the
Seal Partners and Hvide Marine Incorporated, dated March 29, 1996, and amended
July 23, 1996, for the sale of certain assets and operations to Hvide Marine
Incorporated (the "Agreement") and are not intended to be complete presentations
of the Seal Partners' revenues and expenses.
 
     In our opinion, the combined statements referred to above present fairly,
in all material respects, the combined vessel operations of the Seal Partners
for the years ended December 31, 1995, 1994, and 1993, pursuant to the Agreement
described in Note 1, in conformity with generally accepted accounting
principles.

1 BASIS OF PRESENTATION
 
     The accompanying combined financial statement includes certain accounts of:

</TABLE>
 
     Each of the five limited partnerships above (collectively "the Seal
Partners") owns an offshore service ship (collectively "the Seal Partners
Ships"). These entities have been combined because they have common partners and
have collectively entered into an Asset Purchase Agreement to sell certain
assets. There have been no significant intercompany transactions or interrelated
activities between these entities.
 
     The Baltic Seal was purchased by Baltic Seal Partners, Ltd. in February
1994 and was placed in service in August 1994 after a period of drydocking.
 
     According to the terms of the Asset Purchase Agreement dated March 29,
1996, and amended July 23, 1996 the Seal Partners have committed to sell certain
assets which include the Seal Partners Ships and related improvements to Hvide
Marine Incorporated ("Hvide"). In accordance with the July 1996 amendment, Hvide
will purchase the assets for the price of $16.0 million.
 
     The accompanying combined statements of vessel operations include only
operating revenues and direct expenses related solely to the assets to be
acquired by Hvide. Other operating results of the Seal Partners are omitted from
the statements as they do not directly relate to the assets being sold to Hvide.
 
     The accompanying combined statements of vessel operations (i) include the
operating revenues and operating expenses directly related to the operations of
the Seal Partners Ships, and (ii) exclude depreciation, general and
administrative overhead allocations, management fees, interest expense and
income taxes.
 
     General and administrative expenses have been excluded since Seal Partners
have operations other than the vessel operations presented herein. Seal Partners
do not allocate general and administrative expenses among specific operations or
vessels.
 
2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Operating revenues
 
     All operating revenues are earned from time charters and recognized based
on contract day rates.

</TABLE>
 
     The costs of major improvements to the vessels which have been made by the
Seal Partners have not been capitalized and depreciated, are excluded from the
above unaudited schedule, and aggregated $481,765, $3,487,435 and $922,475
during the years ended December 31, 1995, 1994, and 1993, respectively and
$407,604 and $351,575 during the six months ended June 30, 1996 and 1995,
respectively. Additional costs of improvements were incurred during periods
prior to 1993.
 
     Depreciation expense, based on useful lives of 7 to 32 years for the
vessels and approximately three years for the related improvements presented
herein, is approximately $2,093,000, $1,415,000 and $608,000 for the years ended
December 31, 1995, 1994 and 1993, respectively, and $1,121,000 and $1,047,000
for the six months ended June 30, 1996 and 1995, respectively.
 
     The assets of the Seal Partners that are not being sold to Hvide have been
excluded from the table above. No liabilities of the Seal Partners are to be
assumed in connection with the Agreement.
 
4 ALLOCATION OF PURCHASE PRICE (UNAUDITED)
 
     In accordance with the Agreement, as amended, the purchase price of the
assets of $16.0 million will be allocated to the vessels.
 
     Based upon Hvide's policies, the vessels will be depreciated on a straight
line basis over 8 to 26 years.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors of
  Seal Fleet, Inc.
 
     We have audited the accompanying Statements of Assets to be Sold of Seal
Fleet, Inc. and Subsidiaries as of December 31, 1995, 1994 and 1993 and the
related Statements of Vessel Operations for the years then ended. These
financial statements are the responsibility of the management of Seal Fleet,
Inc. Our responsibility is to express an opinion on these financial statements
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.
 
     As described in Note 1, the financial statements referred to above have
been prepared in accordance with the Asset Purchase Agreement between Seal
Fleet, Inc. and Subsidiaries and Hvide Marine Incorporated dated March 29, 1996,
and amended July 23, 1996 for the sale of certain assets and operations to Hvide
Marine Incorporated (the "Agreement") and are not intended to be complete
presentations of Seal Fleet, Inc. and Subsidiaries' assets, liabilities,
revenues and expenses.
 
     In our opinion, the statements referred to above present fairly, in all
material respects, the assets to be sold of Seal Fleet, Inc. and Subsidiaries as
of December 31, 1995, 1994 and 1993 and the related vessel operations for the
years then ended, pursuant to the Agreement described in Note 1, in conformity
with generally accepted accounting principles.

such statements are not intended to be complete financial statements of Seal
Fleet.
 
     The accompanying statements of vessel operations include only operating
revenues and direct expenses related solely to the assets to be acquired by
Hvide. Other operating results of Seal Fleet are omitted from the statements as
they do not directly relate to the assets being sold to Hvide.
 
     The accompanying statements of vessel operations (i) include the operating
revenues and operating expenses directly related to the operations of the Seal
Fleet Ships, and (ii) exclude general and administrative overhead allocations,
intercompany commissions allocated among Seal Fleet, Inc. and its Subsidiaries,
interest expense and income taxes.
 
     General and administrative expenses have been excluded since Seal Fleet has
operations other than the vessel operations presented herein. Seal Fleet does
not allocate general and administrative expenses among specific operations or
vessels.
 
2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Vessels and Improvements
 
     Vessels and improvements include two seismic ships and one supply service
ship and are stated at cost less accumulated depreciation. Depreciation is
computed on the straight-line method using estimated useful lives of twenty
years. Major improvements are capitalized as deferred drydocking and are
amortized over the estimated period benefitted of eighteen months to four years
while replacements, maintenance and repairs which do not improve or extend the
lives of the assets are expensed as incurred. The costs of annual drydocking and
inspections of the ships are expensed as incurred.
 
  Operating revenues
 
     Operating revenues are earned from time charters and are recognized based
on contract day rates for the Seal Fleet Ships.

as deferred drydocking, aggregated $659,780, $22,719 and $476,922 during the
years ended December 31, 1995, 1994 and 1993, respectively, and $296,278 and
$354,445 during the six months ended June 30, 1996 and 1995, respectively.

     Based upon Hvide's policies, the vessels will be depreciated on a straight
line basis over 6 to 11 years and the drydocking costs will be amortized on a
straight line basis from the date purchased to the next required drydocking for
each vessel.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
The Board of Directors and Shareholders
  HVIDE MARINE INCORPORATED
 
     We have audited the accompanying statements of assets to be sold of Gulf
Boat Marine Services, Inc. and E&D Boat Rentals, Inc. (the Companies) as of
September 30, 1994 and 1995, and the related statements of vessel operations for
the years then ended. These statements of assets to be sold and the related
statements of vessel operations are the responsibility of the management of the
Companies. Our responsibility is to express an opinion on the statements of
assets to be sold and the related statements of vessel operations 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 statements of assets to be sold and the
related statements of vessel operations are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the statements of assets to be sold and the related statements of
vessel operations. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall presentation of the statements of assets to be sold and the related
statements of vessel operations. We believe that our audits provide a reasonable
basis for our opinion.
 
     As described in Note 1, the statements of assets to be sold and the related
statements of vessel operations referred to above have been prepared in
accordance with the Asset Purchase Agreement between the Companies and Hvide
Marine Incorporated dated January 15, 1996 for the sale of certain assets to
Hvide Marine Incorporated, and is not intended to be a complete presentation of
the Companies' assets, liabilities, revenue and expenses.
 
     In our opinion, the statements of assets to be sold and the related
statements of vessel operations referred to above present fairly, in all
material respects, the assets to be sold of the Companies at September 30, 1994
and 1995, and its vessel operations for each of the years then ended, pursuant
to the Sale and Purchase Agreement described in Note 1, in conformity with
generally accepted accounting principles.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Articles of Incorporation provides that the Company shall
indemnify each director and officer of the Company to the fullest extent
permitted from time to time by the laws of the State of Florida or any other
applicable laws as presently or hereafter in effect. Section 607.0850 of the
Florida Business Corporation Act currently provides as follows:
 
          (1) A corporation shall have power to indemnify any person who was or
     is a party to any proceeding (other than an action by, or in the right of,
     the corporation), by reason of the fact that he is or was a director,
     officer, employee, or agent of the corporation or is or was serving at the
     request of the corporation as a director, officer, employee, or agent of
     another corporation, partnership, joint venture, trust, or other enterprise
     against liability incurred in connection with such proceeding, including
     any appeal thereof, if he 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. The termination of any
     proceeding by judgment, order, settlement, or conviction or upon a plea of
     nolo contendere or its equivalent shall not, of itself, create a
     presumption that the person did not act in good faith and in a manner which
     he reasonably believed to be in, or not opposed to, the best interests of
     the corporation or, with respect to any criminal action or proceeding, had
     reasonable cause to believe that his conduct was unlawful.
 
          (2) A corporation shall have power to indemnify any person, who was or
     is a party to any proceeding by or in the right of the corporation to
     procure a judgment in its favor by reason of the fact that he is or was a
     director, officer, employee, or agent of the corporation or is or was
     serving at the request of the corporation as a director, officer, employee,
     or agent of another corporation, partnership, joint venture, trust, or
     other enterprise, against expenses and amounts paid in settlement not
     exceeding, in the judgment of the board of directors, the estimated expense
     of litigating the proceeding to conclusion, actually and reasonably
     incurred in connection with the defense or settlement of such proceeding,
     including any appeal thereof. Such indemnification shall be authorized if
     such person acted in good faith and in a manner he reasonably believed to
     be in, or not opposed to, the best interests of the corporation, except
     that no indemnification shall be made under this subsection in respect of
     any claim, issue, or matter as to which
 
                                      II-1
<PAGE>   129
 
     such person shall have been adjudged to be liable unless, and only to the
     extent that, the court in which such proceeding was brought, or any other
     court of competent jurisdiction, shall determine upon application that,
     despite the adjudication of liability but in view of all circumstances of
     the case, such person is fairly and reasonably entitled to indemnity for
     such expenses which such court shall deem proper.
 
          (3) To the extent that a director, officer, employee, or agent of a
     corporation has been successful on the merits or otherwise in defense of
     any proceeding referred to in subsection (1) or subsection (2), or in
     defense of any claim, issue, or matter therein, he shall be indemnified
     against expenses actually and reasonably incurred by him in connection
     therewith.
 
          (4) Any indemnification under subsection (1) or subsection (2), unless
     pursuant to a determination by a court, shall be made by the corporation
     only as authorized in the specific case upon a determination that
     indemnification of the director, officer, employee, or agent is proper in
     the circumstances because he has met the applicable standard of conduct set
     forth in subsection (1) or subsection (2). Such determination shall be
     made:
 
             (a) By the board of directors by a majority vote of a quorum
        consisting of directors who were not parties to such proceeding;
 
             (b) If such a quorum is not obtainable or, even if obtainable, by
        majority vote of a committee duly designated by the board of directors
        (in which directors who are parties may participate) consisting solely
        of two or more directors not at the time parties to the proceeding;
 
             (c) By independent legal counsel:
 
                1. Selected by the board of directors prescribed in paragraph
           (a) or the committee prescribed in paragraph (b); or
 
                2. If a quorum of the directors cannot be obtained for paragraph
           (a) and the committee cannot be designated under paragraph (b),
           selected by majority vote of the full board of directors (in which
           directors who are parties may participate); or
 
             (d) By the stockholders by a majority vote of a quorum consisting
        of stockholders who were not parties to such proceeding or, if no such
        quorum is obtainable, by a majority vote of stockholders who were not
        parties to such proceeding.
 
          (5) Evaluation of the reasonableness of expenses and authorization of
     indemnification shall be made in the same manner as the determination that
     indemnification is permissible. However, if the determination of
     permissibility is made by independent legal counsel, persons specified by
     paragraph (4)(c) shall evaluate the reasonableness of expenses and may
     authorize indemnification.
 
          (6) Expenses incurred by an officer or director in defending a civil
     or criminal proceeding may be paid by the corporation in advance of the
     final disposition of such proceeding upon receipt of an undertaking by or
     on behalf of such director or officer to repay such amount if he is
     ultimately found not to be entitled to indemnification by the corporation
     pursuant to this section. Expenses incurred by other employees and agents
     may be paid in advance upon such terms or conditions that the board of
     directors deems appropriate.
 
          (7) The indemnification and advancement of expenses provided pursuant
     to this section are not exclusive, and a corporation may make any other or
     further indemnification or advancement of expenses of any of its directors,
     officers, employees, or agents, under any bylaw, agreement, vote of
     stockholders or disinterested directors, or otherwise, both as to action in
     his official capacity and as to action in another capacity while holding
     such office. However, indemnification or advancement of expenses shall not
     be made to or on behalf of any director, officer, employee, or agent if a
     judgment or other final adjudication
 
                                      II-2
<PAGE>   130
 
     establishes that his actions, or omissions to act, were material to the
     cause of action so adjudicated and constitute:
 
             (a) A violation of the criminal law, unless the director, officer,
        employee, or agent had reasonable cause to believe his conduct was
        lawful or had no reasonable cause to believe his conduct was unlawful;
 
             (b) A transaction from which the director, officer, employee, or
        agent derived an improper personal benefit;
 
             (c) In the case of a director, a circumstance under which the
        liability provisions of s. 607.0834 are applicable; or
 
             (d) Willful misconduct or a conscious disregard for the best
        interests of the corporation in a proceeding by or in the right of the
        corporation to procure a judgment in its favor or in a proceeding by or
        in the right of a stockholder.
 
          (8) Indemnification and advancement of expenses as provided in this
     section shall continue as, unless otherwise provided when authorized or
     ratified, to a person who has ceased to be a director, officer, employee,
     or agent and shall inure to the benefit of the heirs, executors, and
     administrators of such a person, unless otherwise provided when authorized
     or ratified.
 
          (9) Unless the corporation's articles of incorporation provide
     otherwise, notwithstanding the failure of a corporation to provide
     indemnification, and despite any contrary determination of the board or of
     the stockholders in the specific case, a director, officer, employee, or
     agent of the corporation who is or was a party to a proceeding may apply
     for indemnification or advancement of expenses, or both, to the court
     conducting the proceeding, to the circuit court, or to another court of
     competent jurisdiction. On receipt of an application, the court, after
     giving any notice that it considers necessary, may order indemnification
     and advancement of expenses, including expenses incurred in seeking
     court-ordered indemnification or advancement of expenses, if it determines
     that:
 
             (a) The director, officer, employee, or agent is entitled to
        mandatory indemnification under subsection (3), in which case the court
        shall also order the corporation to pay the director reasonable expenses
        incurred in obtaining court-ordered indemnification or advancement of
        expenses;
 
             (b) The director, officer, employee, or agent is entitled to
        indemnification or advancement of expenses, or both, by virtue of the
        exercise by the corporation of its power pursuant to subsection (7); or
 
             (c) The director, officer, employee, or agent is fairly and
        reasonably entitled to indemnification or advancement of expenses, or
        both, in view of all the relevant circumstances, regardless of whether
        such person met the standard of conduct set forth in subsection (1),
        subsection (2), or subsection (7).
 
          (10) For purposes of this section, the term "corporation" includes, in
     addition to the resulting corporation, any constituent corporation
     (including any constituent of a constituent) absorbed in a consolidation or
     merger, so that any person who is or was a director, officer, employee, or
     agent of a constituent corporation, or is or was serving at the request of
     a constituent corporation as a director, officer, employee, or agent of
     another corporation, partnership, joint venture, trust, or other
     enterprise, is in the same position under this section with respect to the
     resulting or surviving corporation as he would have with respect to such
     constituent corporation if its separate existence had continued.
 
          (11) For purposes of this section:
 
             (a) The term "other enterprises" includes employee benefit plans;
 
             (b) The term "expenses" includes counsel fees, including those for
        appeal;
 
                                      II-3
<PAGE>   131
 
             (c) The term "liability" includes obligations to pay a judgment,
        settlement, penalty, fine (including an excise tax assessed with respect
        to any employee benefit plan), and expenses actually and reasonably
        incurred with respect to a proceeding;
 
             (d) The term "proceeding" includes any threatened, pending, or
        completed action, suit, or other type of proceeding, whether civil,
        criminal, administrative, or investigative, and whether formal or
        informal;
 
             (e) The term "agent" includes a volunteer;
 
             (f) The term "serving at the request of the corporation" includes
        any service as a director, officer, employee, or agent of the
        corporation that imposes duties on such persons, including duties
        relating to an employee benefit plan and its participants or
        beneficiaries; and
 
             (g) The term "not opposed to the best interest of the corporation"
        describes the actions of a person who acts in good faith and in a manner
        he reasonably believes to be in the best interests of the participants
        and beneficiaries of an employee benefit plan.
 
          (12) A corporation shall have power to purchase and maintain insurance
     on behalf of any person who is or was director, officer, employee, or agent
     of the corporation or is or was serving at the request of the corporation
     as a director, officer, employee, or agent of another corporation,
     partnership, joint venture, trust, or other enterprise against any
     liability asserted against him and incurred by him in any such capacity or
     arising out of his status as such, whether or not the corporation would
     have the power to indemnify him against such liability under the provisions
     of this section.
 
     The Underwriting Agreement (Exhibit 1) provides for indemnification by the
Underwriters of the Registrant, its directors and executive officers and by the
Registrant of the Underwriters for certain liabilities, including liabilities
arising under the Securities Act of 1933, as amended (the "Act") and affords
certain rights of contribution with respect thereto.
 
     The Registrant has purchased an insurance policy that provides for
indemnification of the Registrant's executive officers and directors for
liability resulting from their negligence, error, omission or breach of duty
while acting in their capacities as executive officers and directors on any
matter claimed against them by reason of their being executive officers and
directors.

ITEM 17.  UNDERTAKINGS
 
     (1) 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 foregoing provisions, 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.
 
     (2) The undersigned registrant hereby undertakes that:
 
          (a) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of a registration statement in reliance upon Rule 430A and contained in the
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of the
     registration statement as of the time it was declared effective.
 
          (b) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus 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.

DONALDSON, LUFKIN & JENRETTE
     SECURITIES CORPORATION
HOWARD, WEIL, LABOUISSE, 
     FRIEDRICHS INCORPORATED 
As representatives of the
     several underwriters 
     named in Schedule I hereto
c/o Donaldson, Lufkin & Jenrette
     Securities Corporation
277 Park Avenue
New York, New York  10172

Dear Sirs:

     Hvide Marine Incorporated, a Florida corporation (the "Company"), proposes
to issue and sell to the several underwriters named in Schedule I hereto (the
"Underwriters") 3,860,584 shares of Class A Common Stock, par value $0.001 per
share, of the Company, and certain stockholders of the Company named in Schedule
II hereto (the "Selling Stockholders") severally propose to sell to the
Underwriters an aggregate of 139,416 shares of Class A Common Stock of the
Company (certain of which may be in the form of shares of Class B Common Stock
of the Company at the time of sale). The 3,860,584 shares to be sold by the
Company are hereinafter referred to as the "Company Shares" and the 139,416
shares to be sold by the Selling Stockholders are hereinafter referred to as the
"Stockholder Shares." The Company Shares and the Stockholder Shares are
hereinafter collectively referred to as the "Firm Shares."

     The Company also proposes to issue and sell to the Underwriters not more
than 575,000 shares of Class A Common Stock (the "Company Additional Shares") to
the Underwriters, and the Hvide Family Trust II (the "Hvide Trust") proposes to
sell to the Underwriters not more than 25,000 shares of Class A Common Stock
(which may be in the form of shares of Class B Common Stock at the time of sale)
(the "Trust Additional Shares"



<PAGE>   2


and, together with the Company Additional Shares, the "Additional Shares"), if
requested by the Underwriters as provided in Section 2 hereof. The Firm Shares
and the Additional Shares are hereinafter collectively referred to as the
"Shares." The Company, the Hvide Trust and the Selling Stockholders are
hereinafter collectively referred to as the "Sellers."

     1. Registration Statement and Prospectus. The Company has prepared and
filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"Securities Act"), a registration statement on Form S-1 (File No. 333-18525)
including a prospectus relating to the Shares, which may be amended. The
registration statement as amended at the time when it becomes effective,
including information (if any) deemed to be part of the registration statement
at the time of effectiveness pursuant to Rule 430A under the Securities Act and
a registration statement (if any) filed pursuant to Rule 462(b) under the
Securities Act increasing the size of the offering registered under the
Securities Act, is hereinafter referred to as the Registration Statement; and
the prospectus in the form first used to confirm sales of Shares is hereinafter
referred as the Prospectus.

     2. Agreements to Sell and Purchase. On the basis of the representations and
warranties contained in this Agreement, and subject to its terms and conditions,
the Company hereby agrees to issue and sell the Company Shares to the several
Underwriters and each Selling Stockholder, severally and not jointly, hereby
agrees to sell to the several Underwriters the number of Stockholder Shares set
forth opposite such Selling Stockholder's name in Schedule II hereto, and each
of the Underwriters, severally and not jointly, hereby agrees to purchase from
the Company and each Selling Stockholder at a price per share of $_____ (the
"Purchase Price") the respective number of Company Shares and Stockholder Shares
(subject to adjustments to eliminate fractional shares as the Representatives
may determine) that bears the same proportion to the number of Company Shares
and Stockholder Shares to be sold by the Company or such Selling Stockholder, as
the case may be, as the number of Firm Shares set forth in Schedule I hereto
opposite the name of such Underwriter bears to the total number of Firm Shares
set forth opposite the names of all Underwriters in Schedule I hereto.

     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company hereby agrees to
issue and sell to the Underwriters the Company Additional Shares, and the Hvide
Trust hereby agrees to sell to the Underwriters the Trust Additional Shares, and
each of the Underwriters shall have the right to purchase, severally and not
jointly, up to 575,000 Company Additional Shares from the Company at the
Purchase Price and up to 25,000 Trust Additional Shares from the Hvide Trust at
the Purchase Price. Additional Shares may be purchased solely for the purpose of
covering over allotments made in connection with the offering of the Firm 
Shares. The Underwriters may exercise their right to purchase Additional Shares
in whole or in part from time to time by giving written notice thereof to the
Company and the Hvide Trust within 30 days after the date of this Agreement. The
Representatives shall give any such notice on behalf of the Underwriters and
such notice shall specify the aggregate number of Additional Shares to be
purchased pursuant to such exercise and the date for payment and delivery
thereof. The date



                                       2




<PAGE>   3


specified in any such notice shall be a business day (i) no earlier than the
Closing Date (as hereinafter defined) and (ii) no later than 10 business days
after such notice has been given. If any Additional Shares are to be purchased,
each Underwriter, severally and not jointly, agrees to purchase from the Hvide
Trust the number of Trust Additional Shares (subject to such adjustments to
eliminate fractional shares as the Representatives may determine) which bears
the same proportion to the total number of Trust Additional Shares to be
purchased by the Underwriters from the Hvide Trust as the number of Firm Shares
set forth opposite the name of such Underwriter in Schedule I hereto bears to
the total number of Firm Shares. If more than 25,000 Additional Shares are to be
purchased, each Underwriter, severally and not jointly, agrees to purchase from
the Company the number of Company Additional Shares (subject to such adjustments
to eliminate fractional shares as the Representatives may determine) which bears
the same proportion to the total number of Company Additional Shares to be
purchased by the Underwriters from the Company as the number of Firm Shares set
forth opposite the name of such Underwriter in Schedule I hereto bears to the
total number of Firm Shares.

     The Company shall, concurrently with the execution of this Agreement,
deliver an agreement executed by (i) each of the directors and officers of the
Company and (ii) each stockholder listed on Annex 1 hereto, pursuant to which
each such person agrees, not to offer, sell, contract to sell, grant any option
to purchase, or otherwise dispose of any Class A Common Stock or other common
stock of the Company or any securities convertible into or exercisable or
exchangeable for such Class A Common Stock or other common stock of the Company
(collectively, the "Common Stock") or in any other manner transfer all or a
portion of the economic consequences associated with the ownership of any such
Common Stock, except to the Underwriters pursuant to this Agreement, for a
period of 90 days after the date of the Prospectus without the prior written
consent of Donaldson, Lufkin & Jenrette Securities Corporation. Notwithstanding
the foregoing, during such period (i) the Company may grant options to purchase
shares of Class A Common Stock pursuant to the Company's existing stock option
plans and (ii) the Company may issue shares of its Common Stock pursuant to its
employee stock purchase plan and upon the exercise of an option or warrant or
the conversion of a security outstanding on the date hereof.

     3. Terms of Public Offering.  The Sellers are advised by you that the
Underwriters propose (i) to make a public offering of their respective portions
of the Shares as soon after the effective date of the Registration Statement as
in your judgment is advisable and (ii) initially to offer the Shares upon the
terms set forth in the Prospectus.

     4. Delivery and Payment. Delivery to the Underwriters of and payment for
the Firm Shares shall be made at 10:00 a.m., New York City time, on the third
business day, unless otherwise permitted or required by the Commission pursuant
to Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), following the date of the offering (the "Closing Date"), at
such place as you shall designate. The Closing Date and the location of delivery
of and the form of payment for the Firm Shares may be varied by agreement
between you and the Company.



                                       3

<PAGE>   4

     Delivery to the Underwriters of and payment for any Additional Shares to be
purchased by the Underwriters shall be made at such place as you shall designate
at 10:00 a.m., New York City time, on the date specified in the applicable
exercise notice given by you pursuant to Section 2 (an "Option Closing Date").
Any such Option Closing Date and the location of delivery of and the form of
payment for such Additional Shares may be varied by agreement between you and
the Company.

     Certificates for the Shares shall be registered in such names and issued in
such denominations as you shall request in writing not later than two (2) full
business days prior to the Closing Date or an Option Closing Date, as the case
may be. Such certificates shall be made available to you for inspection not
later than 9:30 a.m., New York City time, on the business day next preceding the
Closing Date or an Option Closing Date, as the case may be. Certificates in
definitive form evidencing the Shares shall be delivered to you on the Closing
Date or an Option Closing Date, as the case may be, with any transfer taxes
thereon duly paid by the respective Sellers, for the respective accounts of the
several Underwriters, against payment of the Purchase Price therefor by
certified or official bank checks payable in New York Clearing House funds to
the order of the applicable Sellers.

     5. Agreements of the Company.  The Company agrees with you:

           (a) To use its best efforts to cause the Registration Statement to
      become effective at the earliest possible time.

           (b) To advise you promptly and, if requested by you, to confirm such
      advice in writing, (i) when the Registration Statement has become
      effective and when any post-effective amendment to it becomes effective,
      (ii) of any request by the Commission for amendments to the Registration
      Statement or amendments or supplements to the Prospectus or for additional
      information, (iii) of the issuance by the Commission of any stop order
      suspending the effectiveness of the Registration Statement or of the
      suspension of qualification of the Shares for offering or sale in any
      jurisdiction, or the initiation of any proceeding for such purposes, and
      (iv) of the happening of any event during the period referred to in
      paragraph (e) below which makes any statement of a material fact made in
      the Registration Statement or the Prospectus untrue or which requires the
      making of any additions to or changes in the Registration Statement or the
      Prospectus in order to make the statements therein not misleading. If at
      any time the Commission shall issue any stop order suspending the
      effectiveness of the Registration Statement, the Company will make every
      reasonable effort to obtain the withdrawal or lifting of such order at the
      earliest possible time.

           (c) To furnish to you, without charge, three signed copies of the
      Registration Statement as first filed with the Commission and of each
      amendment to it, including all exhibits, as you may reasonably request,
      and to furnish to you and each Underwriter designated by you such number
      of conformed copies of the Registration Statement as so filed and of each
      amendment to it, without exhibits, as you may reasonably request.




                                       4
<PAGE>   5

           (d) Not to file any amendment or supplement to the Registration
      Statement, whether before or after the time when it becomes effective, or
      to make any amendment or supplement to the Prospectus of which you shall
      not previously have been advised or to which you shall reasonably object;
      and to prepare and file with the Commission, promptly upon your reasonable
      request, any amendment to the Registration Statement or supplement to the
      Prospectus which may be necessary or advisable in connection with the
      distribution of the Shares by you, and to use its best efforts to cause
      any such amendment to become promptly effective.

           (e) Promptly after the Registration Statement becomes effective, and
      from time to time thereafter for such period as in the opinion of counsel

           (d) Exhibit 21 to the Registration Statement sets forth a complete

      "Subsidiaries"). Each of the Company and the Subsidiaries has been duly
      incorporated or formed, is validly existing as a corporation, limited
      liability company or partnership in good standing under the laws of its
      jurisdiction of incorporation or formation and has the power and authority

      ownership interests in, each of the Subsidiaries have been duly authorized
      and validly issued and are fully paid and non-assessable, and are owned by
      the Company, free and clear of any security interest, claim, lien,
      encumbrance or adverse interest of any nature.

      Stock, conforms as to legal matters to the description thereof contained
      in the Prospectus.

      of its respective charter, bylaws or other organizational or constituent
      documents (collectively, "Constituent Documents") or in default in the
      performance of any obligation, agreement or condition contained in any
      bond, debenture, note or any other evidence of indebtedness or in any
      other agreement, indenture or instrument material to the conduct of the
      business of the Company and the Subsidiaries, taken as a whole, to which
      the Company or any of the Subsidiaries is a party or by which it or any of
      the Subsidiaries or their respective property is bound.

           (i) The execution, delivery and performance of this Agreement,
      compliance by the Company with all the provisions hereof and the
      consummation of the Current Acquisitions (as defined in the Prospectus)
      and the transactions contemplated hereby will not require any consent,
      approval, authorization or other order of any court, regulatory body,
      administrative agency or other governmental body (except as such may be
      required under the securities or Blue Sky laws of the various states) and
      will not conflict with or constitute a breach of any of the terms or
      provisions of, or a default under, the Constituent Documents of the
      Company or any of the Subsidiaries or any agreement, indenture or other
      instrument to which it or any of the Subsidiaries is a party or by which
      it or any of the Subsidiaries or their respective property is bound, or
      violate or conflict with any laws, administrative regulations or rulings
      or court decrees applicable to the Company, any of the Subsidiaries or
      their respective property.

           (j) Except as otherwise set forth in the Prospectus, there are no
      material legal or governmental proceedings pending to which the Company or
      any of the Subsidiaries is a party or of which any of their respective
      property is the subject, and, to the best of the Company's knowledge, no
      such proceedings are threatened or 




                                       8

      contemplated. No contract or document of a character required to be
      described in the Registration Statement or the Prospectus or to be filed
      as an exhibit to the Registration Statement is not so described or filed
      as required.

           (k) Neither the Company nor any of the Subsidiaries has violated or
      is in violation of any foreign, federal, state or local law or regulation
      relating to the protection of human health and safety, the environment or
      hazardous or toxic substances or wastes, pollutants or contaminants
      ("Environmental Laws"), nor any federal or state law relating to
      discrimination in the hiring, promotion or pay of employees nor any
      applicable federal or state wages and hours laws, nor any provisions of
      the Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
      or the rules and regulations promulgated thereunder, which in each case
      might result in any material adverse change in the business, prospects,
      financial condition or results of operation of the Company and the
      Subsidiaries, taken as a whole.

          (l) Each of the Company and the Subsidiaries has such permits,
      certificates, endorsements, licenses, franchises and authorizations of
      governmental or regulatory authorities ("Permits"), including, without
      limitation, under any applicable Environmental Laws, as are necessary to
      own, lease, charter and operate its respective Vessels and other
      properties and to conduct its business; each of the Company and the
      Subsidiaries has fulfilled and performed all of its material obligations
      with respect to such Permits and no event has occurred which allows, or
      after notice or lapse of time would allow, revocation or termination
      thereof or results in any other material impairment of the rights of the
      holder of any such permit; and, except as described in the Prospectus,
      such Permits contain no restrictions that are materially burdensome to the
      Company or any of the Subsidiaries.

           (m) In the ordinary course of its business, the Company conducts a
      periodic review of the effect of Environmental Laws on the business,
      operations and properties of the Company and the Subsidiaries, in the
      course of which it identifies and evaluates associated costs and
      liabilities (including, without limitation, any capital or operating
      expenditures required for clean-up or closure of properties or compliance
      with Environmental Laws or any Permits or any related constraints on
      operating activities and any potential liabilities to third parties). On
      the basis of such review, the Company has reasonably concluded that such
      associated costs and liabilities would not, singly or in the aggregate,
      have a material adverse effect on the Company and the Subsidiaries, taken
      as a whole.

           (n) Except as otherwise set forth in the Prospectus or such as are
      not material to the business, prospects, financial condition or results of
      operation of the Company and the Subsidiaries, taken as a whole, the
      Company and each of the Subsidiaries has good and marketable title, free
      and clear of all liens, claims, encumbrances and restrictions except liens
      for taxes not yet due and payable, to all property and assets described in
      the Registration Statement as being owned by it. All leases and charters
      to which the Company or any of the Subsidiaries is a party are valid 




                                       9

      and binding and no default has occurred or is continuing thereunder,
      which might result in any material adverse change in the business,
      prospects, financial condition or results of operation of the Company and
      the Subsidiaries taken as a whole, and the Company and the Subsidiaries
      enjoy peaceful and undisturbed possession under all such leases and
      charters to which any of them is a party as lessee or charterer with such
      exceptions as do not materially interfere with the use made by the Company
      or such Subsidiary.

      insurance.

      effect to the transactions and circumstances referred to therein; and the
      other financial and statistical information and data set forth in the
      Registration Statement and the Prospectus (and any amendment or supplement
      thereto) are, in all material respects, accurately presented and prepared

      Prospectus; each of the Company and the Subsidiaries has fulfilled and
      performed all of its material obligations with respect to such Permits and

      case to such qualification as may be set forth in the Prospectus; and,

      agreement of such Selling Stockholder enforceable in accordance with its
      terms, except as rights to indemnity and contribution hereunder may be
      limited by applicable law, and subject to bankruptcy, insolvency,
      reorganization, moratorium, fraudulent transfer and similar laws of
      general applicability affecting creditors' rights and to general equity
      principles.

           (e) The power of attorney (such power of attorney and each similar
      power of attorney may be referred to herein as a "Power of Attorney")
      signed by such Selling Stockholder appointing Kevin A. Macdonald and
      Robert B. Calhoun, or any of them acting singly, as its attorney-in-fact
      to the extent set forth therein with regard to the transactions
      contemplated hereby and by the Registration Statement and the Custody
      Agreement has been duly authorized, executed and delivered by or on behalf
      of such Selling Stockholder and is a valid and binding instrument of such
      Selling Stockholder enforceable in accordance with its terms, and,
      pursuant to such power of attorney, such Selling Stockholder has
      authorized Kevin A. Macdonald and Robert B. Calhoun, or any of them acting

           (f) Such Selling Stockholder has not taken, and will not take,
      directly or indirectly, any action designed to, or which might reasonably
      be expected to, cause or result in stabilization or manipulation of the
      price of any security of the Company to facilitate the sale or resale of
      the Shares pursuant to the distribution contemplated by this Agreement,

           (g) The execution, delivery and performance of this Agreement by
      such Selling Stockholder, compliance by such Selling Stockholder with all
      the provisions hereof and the consummation of the transactions
      contemplated hereby by such Selling Stockholder will not (i) require any

      individual, or (except as would not have a material adverse effect) or any
      agreement, indenture or other instrument to which such Selling Stockholder
      is a party or by which such Selling Stockholder or property of such
      Selling Stockholder is bound, or (iii) (except as would not have a
      material adverse effect) violate or conflict with any laws, administrative
      regulation or ruling or court decree applicable to such Selling
      Stockholder or property of such Selling Stockholder.

           (h) Such Selling Stockholder has reviewed such part of the
      Registration Statement included in the table and the footnotes thereto
      under the caption "Principal and Selling Stockholders" which specifically
      relate to such Selling Stockholder and such part of the Registration
      Statement does not, and will not on the Closing Date, contain any untrue
      statement of a material fact or omit to state any material fact required

           (b) It is the lawful owner of the Shares to be sold by it pursuant to

      or Blue Sky Laws.

           (e) The Power of Attorney signed by the Hvide Trust appointing J.
      Erik Hvide and John H. Blankley, or any of them acting singly, as its
      attorney-in-fact to the extent set forth therein with regard to the
      transactions contemplated hereby and by the Registration Statement and the
      Custody Agreement has been duly authorized, executed and delivered by or
      on behalf of the Hvide Trust and is a valid and binding instrument of the
      Hvide Trust in accordance with its terms, and, pursuant to such Power of
      Attorney, the Hvide Trust has authorized J. Erik Hvide and John H.
      Blankley, or any of them acting singly, to execute and deliver on its
      behalf this Agreement and any other document necessary or desirable in

      distribution contemplated by this Agreement, and other than as permitted
      by the Securities Act, the Hvide Trust has not distributed and will not
      distribute any prospectus or other offering material in connection with

           (h) it has reviewed such parts of the Registration Statement under
      the caption "Principal and Selling Stockholders" which specifically relate
      to the Hvide Trust and such part of the Registration Statement does not,
      and will not on the Closing Date, contain any untrue statement of a
      material fact or omit to state any material fact required to be stated
      therein or necessary to make the statements therein, in light of the
      circumstances under which they were made, not misleading.

           (i) At any time during the period described in Section 5(e), if there
      is any change in the information referred to in paragraph (h) above, the
      Hvide Trust will immediately notify you of such change.

      9. Indemnification.

          (a) The Company agrees to indemnify and hold harmless each Underwriter
     and each person, if any, who controls any Underwriter within the meaning of
     Section 15 of the Securities Act or Section 20 of the Exchange Act, from
     and against any and all losses, claims, damages, liabilities and judgments
     caused by any untrue statement or alleged untrue statement of a material
     fact contained in the Registration Statement or the Prospectus (as amended
     or supplemented if the Company shall have furnished any amendments or
     supplements thereto) or any preliminary prospectus, or caused by any
     omission or alleged omission to state therein a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading, except insofar as such losses, claims, damages, liabilities or
     judgments are caused by any such untrue statement or omission or alleged
     untrue statement or omission based upon information relating to any
     Underwriters furnished in writing to the Company by or on behalf of any
     Underwriter through you expressly for use therein.

          (b) Each Selling Stockholder, severally and not jointly, agrees to
     indemnify and hold harmless each Underwriter and each person, if any, who
     controls any Underwriter within the meaning of Section 15 of the Securities
     Act or Section 20 of the Exchange Act, to the same extent as to the
     foregoing indemnity from the Company, but only with reference to
     information furnished to the Company by the Selling Stockholders expressly
     for use in the Registration Statement, the Prospectus or any preliminary
     prospectus. The Company, the Underwriters, the Hvide Trust and the Selling
     Stockholders agree that, for all purposes of this Agreement, the only
     information so furnished to the Company by each such Selling Stockholder is
     the information which specifically relates to such Selling Stockholder
     included in the table and footnotes related thereto under the caption
     "Principal and Selling Stockholders." Notwithstanding anything to the
     contrary contained in this paragraph (b), the indemnity provided by each
     Selling Stockholder and the Hvide Trust hereunder shall be limited to the
     total amount received by it pursuant to Section 2 hereof for the Shares
     sold by it hereunder.

          (c) The Hvide Trust agrees to indemnify and hold harmless each
     Underwriter and each person, if any, who controls any Underwriter within
     the meaning of Section 15 of the Securities Act or Section 20 of the
     Exchange Act, to the same extent as to the foregoing indemnity from the
     Company, but only with reference to information 



                                       16
<PAGE>   17


      furnished to the Company by the Hvide Trust expressly for use in the
      Registration Statement, the Prospectus or any preliminary prospectus. The
      Company, the Underwriters, the Selling Stockholders and the Hvide Trust
      agree that, for all purposes of this Agreement, the only information so
      furnished to the Company by the Hvide Trust is the information which
      relates to the Hvide Trust under the caption "Principal and Selling
      Stockholders."

          (d) Each Underwriter agrees, severally and not jointly, to indemnify
     and hold harmless the Company, its directors, its officers who sign the
     Registration Statement and any person controlling the Company within the
     meaning of Section 15 of the Securities Act or Section 20 of the Exchange
     Act, each Selling Stockholder, the Hvide Trust, and each person, if any,
     controlling such Selling Stockholder or the Hvide Trust within the meaning
     of Section 15 of the Securities Act and Section 20 of the Exchange Act to
     the same extent as the foregoing indemnity from the Company to each
     Underwriter, but only with reference to information relating to such
     Underwriter furnished in writing by or on behalf of such Underwriter
     through you expressly for use in the Registration Statement, the Prospectus
     or any preliminary prospectus. In case any action shall be brought against
     the Company, any of its directors, any such officer or any person
     controlling the Company, any Selling Stockholder or any person controlling
     such Selling Stockholder based on the Registration Statement, the
     Prospectus or any preliminary prospectus and in respect of which indemnity
     may be sought against any Underwriter, the Underwriter shall have the
     rights and duties given to the Sellers (except that if any Seller shall
     have assumed the defense thereof such Underwriter shall not be required to
     do so, but may employ separate counsel therein and participate in the
     defense thereof but the fees and expenses of such counsel shall be at the
     expense of such Underwriter), and the Company, its directors, any such
     officers and any person controlling the Company, the Selling Stockholders
     and any person controlling such Selling Stockholders and the Hvide Trust
     and any person controlling the Hvide Trust shall have the rights and duties
     given to the Underwriters, by Section 9(e).

          (e) In case any action shall be brought against any Underwriter or any
     person controlling such Underwriter, based upon any preliminary prospectus,
     the Registration Statement or the Prospectus or any amendment or supplement
     thereto and with respect to which indemnity may be sought against the
     Company or any Selling Stockholder or the Hvide Trust, such Underwriter
     shall promptly notify the Company and the Selling Stockholders and the
     Hvide Trust in writing and the Company or the Selling Stockholders or the
     Hvide Trust, as appropriate, shall assume the defense thereof, including
     the employment of counsel reasonably satisfactory to such indemnified party
     and payment of all fees and expenses. Any Underwriter or any such
     controlling person shall have the right to employ separate counsel in any
     such action and participate in the defense thereof, but the fees and
     expenses of such counsel shall be at the expense of such Underwriter or
     such controlling person unless (i) the employment of such counsel has been
     specifically authorized in writing by the Company, (ii) the Company, the
     Hvide Trust and the Selling Stockholders shall have failed to assume the
     defense and employ counsel or (iii) the named parties to any such action
     (including any impleaded 



                                       17
<PAGE>   18

      parties) include both such Underwriter or such controlling person
      and the Company, the Hvide Trust or any Selling Stockholder, as the case
      may be, and such Underwriter or such controlling person shall have been
      advised by such counsel that there may be one or more legal defenses
      available to it which are different from or additional to those available
      to the Company, the Hvide Trust or the Selling Stockholders, as the case
      may be, (in which case the Company, the Hvide Trust and the Selling
      Stockholders shall not have the right to assume the defense of such action
      on behalf of such Underwriter or such controlling person, it being
      understood, however, that the Company, the Hvide Trust and the Selling
      Stockholders shall not, in connection with any one such action or separate
      but substantially similar or related actions in the same jurisdiction
      arising out of the same general allegations or circumstances, be liable
      for the fees and expenses of more than one separate firm of attorneys (in
      addition to any local counsel) for all such Underwriters and controlling
      persons, which firm shall be designated in writing by Donaldson, Lufkin &
      Jenrette Securities Corporation and that all such fees and expenses shall
      be reimbursed as they are incurred). A Seller shall not be liable for any
      settlement of any such action effected without the written consent of such
      Seller but, if settled with the written consent of such Seller, such
      Seller agrees to indemnify and hold harmless any Underwriter and any such
      controlling person from and against any loss or liability by reason of
      such settlement. Notwithstanding the immediately preceding sentence, if in
      any case where the fees and expenses of counsel are at the expense of the
      indemnifying party and an indemnified party shall have requested the
      indemnifying party to reimburse the indemnified party for such fees and
      expenses of counsel as incurred, such indemnifying party agrees that it
      shall be liable for any settlement of any action effected without its
      written consent if (i) such settlement is entered into more than ten
      business days after the receipt by such indemnifying party of the
      aforesaid request and (ii) the indemnifying party shall have failed to
      reimburse the indemnified party in accordance with such request for
      reimbursement prior to the date of such settlement. No indemnifying party
      shall, without the prior written consent of the indemnified party, effect
      any settlement of any pending or threatened proceeding in respect of which
      any indemnified party is or could have been a party and indemnity could
      have been sought hereunder by such indemnified party, unless such
      settlement includes an unconditional release of such indemnified party
      from all liability on claims that are the subject matter of such
      proceeding.

           (f) If the indemnification provided for in this Section 9 is
      unavailable to an indemnified party in respect of any losses, claims,
      damages, liabilities or judgments referred to therein, then each
      indemnifying party, in lieu of indemnifying such indemnified party, shall
      contribute to the amount paid or payable by such indemnified party as a
      result of such losses, claims, damages, liabilities and judgments (i) in
      such proportion as is appropriate to reflect the relative benefits
      received by the Sellers on the one hand and the Underwriters on the other
      hand from the offering of the Shares or (ii) if the allocation provided by
      clause (i) above is not permitted by applicable law, in such proportion as
      is appropriate to reflect not only the relative benefits referred to in
      clause (i) above but also the relative fault of the Sellers and the
      Underwriters in connection with the statements or omissions which resulted
      in such losses, claims, damages, liabilities or 



                                       18
<PAGE>   19

      judgments, as well as any other relevant equitable considerations.
      The relative benefits received by the Sellers and the Underwriters shall
      be deemed to be in the same proportion as the total net proceeds from the
      offering (before deducting expenses) received by the Sellers, and the
      total underwriting discounts and commissions received by the Underwriters,
      bear to the total price to the public of the Shares, in each case as set
      forth in the table on the cover page of the Prospectus. The relative fault
      of the Sellers and the Underwriters shall be determined by reference to,
      among other things, whether the untrue or alleged untrue statement of a
      material fact or the omission to state a material fact relates to
      information supplied by the Company, the Hvide Trust, the Selling
      Stockholders or the Underwriters and the parties' relative intent,
      knowledge, access to information and opportunity to correct or prevent
      such statement or omission.

          The Sellers and the Underwriters agree that it would not be just and
     equitable if contribution pursuant to this Section 9(f) were determined by
     pro rata allocation (even if the Underwriters were treated as one entity
     for such purpose) or by any other method of allocation which does not take
     account of the equitable considerations referred to in the immediately
     preceding paragraph. The amount paid or payable by an indemnified party as
     a result of the losses, claims, damages, liabilities or judgments referred
     to in the immediately preceding paragraph shall be deemed to include,
     subject to the limitations set forth above, any legal or other expenses
     reasonably incurred by such indemnified party in connection with
     investigating or defending any such action or claim. Notwithstanding the
     provisions of this Section 9, (x) no Underwriter shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Shares underwritten by it and distributed to the public were
     offered to the public exceeds the amount of any damages which such
     Underwriter has otherwise been required to pay by reason of such untrue or
     alleged untrue statement or omission or alleged omission and (y) no Selling
     Stockholder or the Hvide Trust shall be required to contribute any amount
     in excess of the amount by which the total amount received by it pursuant
     to Section 2 hereof for the Shares sold by it hereunder exceeds the amount
     of any damages which such Selling Stockholder has otherwise been required
     to pay by reason of such untrue or alleged untrue statement or omission or
     alleged omission. No person guilty of fraudulent misrepresentation (within
     the meaning of Section 11(f) of the Securities Act) shall be entitled to
     contribution from any person who was not guilty of such fraudulent
     misrepresentation. The Underwriters' obligations to contribute pursuant to
     this Section 9(f) are several in proportion to the respective number of
     Shares purchased by each of the Underwriters hereunder and not joint.

          (g) Each of the Company and the Hvide Trust hereby designates the
     General Counsel of the Company at the address listed on the cover of the
     Registration Statement, and each other Seller hereby designates Kevin A.
     Macdonald at the address for the Selling Stockholders listed in Section 13
     herein, in each case as its authorized agent, upon which process may be
     served in any action, suit or proceeding which may be instituted in any
     state or federal court in the State of New York by any Underwriter or
     person controlling an Underwriter asserting a claim for indemnification or
     contribution under or pursuant to this Section 9, and each Seller will
     accept the jurisdiction of such 



                                       19
<PAGE>   20

      court in such action, and waives, to the fullest extent permitted by
      applicable law, any defense based upon lack of personal jurisdiction or
      venue. A copy of any such process shall be sent or given to such Seller,
      at the address for notices specified in Section 13.

      10. Conditions of Underwriters' Obligations.  The several obligations of
the Underwriters to purchase the Firm Shares under this Agreement are subject
to the satisfaction of each of the following conditions:

                       (i) each of the Company, the Subsidiaries and the Hvide
                  Trust has been duly incorporated or formed, is validly
                  existing as a corporation, limited liability company,
                  partnership or trust, in good standing under the laws of its

Dyer Ellis & Joseph shall deliver to the Underwriters a copy of the opinion
relied upon and state that they are justified in relying thereon. In giving such
opinions, such counsel (i) may state that when a statement is qualified by "to

have actual knowledge and (ii) may state that when a statement is qualified by
"after due inquiry" or similar phrase, it is intended to indicate that attorneys
in such firm have participated in conferences with officers and other
representatives of the Company and such firm has received written
representations from the Company or its officers regarding the subject matter
referenced in such statement.

            in which the nature of its business or its ownership or leasing of
            property requires such qualification, except where the failure to be

            Selling Stockholder.

                 (ii) this Agreement has been duly authorized, executed and
            delivered by such Selling Stockholder and is a valid and binding

      11. Effective Date of Agreement and Termination.  This Agreement shall
become effective upon the later of (i) execution of this Agreement and (ii)
when notification of the effectiveness of the Registration Statement has been
released by the Commission.

      This Agreement may be terminated at any time prior to the Closing Date by
you by written notice to the Sellers if any of the following has occurred: (i)
since the respective dates as of which information is given in the Registration
Statement and the Prospectus, any adverse change or development involving a
prospective adverse change in the condition, financial or otherwise, of the
Company or any of the Subsidiaries or the earnings, affairs, or business
prospects of the Company or any of the Subsidiaries, whether or not arising in
the ordinary course of business, which would, in your judgment, make it
impracticable to market the Shares on the terms and in the manner contemplated
in the Prospectus, (ii) any outbreak or escalation of hostilities or other
national or international calamity or crisis or change in economic conditions or
in the financial markets of the United States or elsewhere that, in your
judgment, is material and adverse and would, in your judgment, make it
impracticable to market the Shares on the terms and in the manner contemplated

federal or New York State authorities or (vi) the taking of any action by any
federal, state or local government or agency in respect of its monetary or

     If on the Closing Date or on an Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase the Firm
Shares or Additional Shares, as the case may be, which it or they have agreed to
purchase hereunder on such date and the aggregate number of Firm Shares or
Additional Shares, as the case may be, which such defaulting Underwriter or
Underwriters, as the case may be, agreed but failed or refused to purchase is
not more than one-tenth of the total number of Shares to be purchased on such
date by all Underwriters, each non-defaulting Underwriter shall be obligated
severally, in the proportion which the number of Firm Shares set forth opposite
its name in Schedule I bears to the total number of Firm Shares which all the
non-defaulting Underwriters, as the case may be, have agreed to purchase, or in
such other proportion as you may specify, to purchase the Firm Shares or
Additional Shares, as the case may be, which such defaulting Underwriter or
Underwriters, as the case may be, agreed but failed or refused to purchase on
such date; provided that in no event shall the number of Firm Shares or
Additional Shares, as the case may be, which any Underwriter has agreed to
purchase pursuant to Section 2 hereof be increased pursuant to this Section 10
by an amount in excess of one-ninth of such number of Firm Shares or Additional
Shares, as the case may be, without the written consent of such Underwriter. If
on the Closing Date or on an Option Closing Date, as the case may be, any
Underwriter or Underwriters shall fail or refuse to purchase Firm Shares, or
Additional Shares, as the case may be, and the aggregate number of Firm Shares
or Additional Shares, as the case may be, with respect to which such default
occurs is more than one-tenth of the aggregate number of Shares to be purchased
on such date by all Underwriters and arrangements satisfactory to you and the
Sellers for purchase of such Shares are not made within 48 hours after such
default, this Agreement will terminate without liability on the part of any
non-defaulting Underwriter and the applicable Sellers. In any such case which
does not result in termination of this Agreement, either you or the Sellers
shall have the right to postpone the Closing Date or the applicable Option
Closing Date, as the case may be, but in no event for longer than seven days, in
order that the required changes, if any, in the Registration Statement and the
Prospectus or any other documents or arrangements may be effected. Any action
taken under this paragraph shall not relieve any defaulting Underwriter from
liability in respect of any default of any such Underwriter under this
Agreement.

the Selling Stockholders and the Hvide Trust, severally and not jointly, agrees

officers or directors of the Company or any controlling person of the Sellers,
(ii) acceptance of the Shares and payment for them hereunder and (iii)

disbursements of counsel) reasonably incurred by them.

January 28, 1997

Hvide Marine Incorporated
2200 Eller Drive
Ft. Lauderdale, FL 33316

Ladies and Gentlemen:

We have acted as counsel for Hvide Marine Incorporated, a Florida corporation
(the"Company"), in connection with the issuance and sale pursuant to the
Company's registration statement on Form S-1, File No. 333-18525, (the
"Registration Statement") of up to 4,600,000 shares of its Class A Common Stock,
par value $0.001 per share (the "Shares"). Based upon our examination of such
corporate records and other documents and such questions of law as we have
deemed necessary and appropriate, we are of the opinion that the Shares have
been duly authorized and, when sold as provided in the Underwriting Agreement
described in the Registration Statement, will be validly issued, fully paid, and
non-assessable.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

Very truly yours,

Dyer Ellis & Joseph PC

     Facility shall be made on the Maturity Date for such Facility.

     SECTION 1.024 Interest. (a) The Borrowers shall pay interest on the unpaid
principal amount of each Advance from the Drawdown Date for such Advance until
the principal amount of such Advance is paid in full, payable on each Interest
Payment Date with respect to each such Advance. Notwithstanding the preceding
sentence of this Section 2.04(a), all interest accrued on any


                                      -21-

<PAGE>   23



Advance outstanding on the Maturity Date of such Advance shall be paid on the
Maturity Date for such Advance.

     (b) As long as any Advance shall be outstanding, and payment of the
principal thereof and interest thereon shall not be in default, interest on the
Advance shall be payable at an interest rate which shall be adjusted as provided
in this Section, and in the case of the Alternate Base Rate and to reflect any
change in the Applicable Margin, as set forth herein during such Interest
Period, and which shall be determined as follows:

          (i) with respect to each day of the period commencing on and following
     a Drawdown Date and for each day of each successive Interest Period
     thereafter, the Borrowers shall pay interest on each Advance in its
     entirety or in one or more tranches permitted under Section 2.04(b)(ii) at
     an interest rate equal to the sum of (y) the Applicable Margin plus (z) the
     Alternate Base Rate or the LIBOR Rate, as the case may be, subject to
     periodic adjustment as provided in Section 2.04(b)(iii);

          (ii) with respect to each Interest Period, the Borrowers shall, by
     telex notice to be received by the Administrative Agent by 10 A.M. New York
     time at least four Business Days (one Business Day, in the case of an
     Advance bearing interest at Alternate Base Rate) prior to the commencement
     of each such successive period, elect the Applicable Rate and elect an
     Interest Period of one, two, three or six months duration in the case of
     LIBOR Rate, and such other period in the case of the Alternate Base Rate,
     and one or more but no more than four tranches in total for all outstanding
     Advances, provided each tranche shall be in an amount not less than the
     scheduled principal amount due on the Maturity Date; provided the Borrowers
     shall select Interest Periods, and if necessary shall select as the final
     Interest Period for each Advance an Interest Period less than one month in
     duration, so that the maturity date of each Advance shall be the last day
     of the Interest Period for such Advance; provided that if the Borrowers
     shall fail to elect the Applicable Rate or an Interest Period as herein
     provided, and so long as any Event of Default has not occurred and is
     continuing, the Administrative Agent shall elect the relevant Applicable
     Rate and the Interest Period, which may be one day;

          (iii) (A) the interest payable on each Advance during each successive
     Interest Period shall be adjusted as set forth herein by the Administrative
     Agent for any change in the Applicable Margin in addition to adjustments in
     respect of the Alternate Base Rate, if such rate is then used. As to the
     Letter of Credit and as to all other Advances beginning from January 1,
     1998, the Applicable Margin for each Interest Period (and each day thereof)
     shall


                                      -22-

<PAGE>   24



     be determined by the Administrative Agent (or the Letter of Credit Agent,
     as the case may be) subject to further adjustment from time to time
     pursuant to paragraph (B) of this sub-section (iii). In respect of the
     Advances the highest Applicable Margin shall be in effect unless the
     following test is met on a rolling four quarter basis:

     For the first three quarters following the IPO, the Administrative Agent
     shall use Hvide's Pro Forma Consolidated Historical Financial Statements as
     presented in the S-1 for purposes of determining whether the foregoing
     tests have been met. From the fourth quarter following the IPO Date until
     the Maturity Date, the Administrative Agent shall use the Borrowers' most
     recent quarterly financial statements for purposes of determining whether
     the foregoing tests have been met.

          (B) To the extent of any change in the Applicable Margin during any
     Interest Period, the Administrative Agent shall give prompt written notice
     to the Borrowers and the Banks (a "Notice of Margin Adjustment") specifying
     the amount, if any, of additional interest payable by the Borrowers, or
     excess interest paid by the Borrowers, as the case may be, as a result of
     such change in the Applicable Margin (such amount, the "Relevant Amount").
     The Borrowers shall immediately pay to the Administrative Agent any such
     Relevant Amount specified as payable in the Notice of Margin Adjustment,
     together with interest to the date of payment calculated as for an Advance;
     any Relevant Amount specified in the Notice of Margin Adjustment as an
     excess payment by the Borrowers shall be credited to interest payable by
     the Borrowers on the next Interest Payment Date;

          (iv) the Administrative Agent shall give prompt notice to the
     Borrowers and the Banks of the applicable interest rate determined by the
     Administrative Agent for purposes of Section 2.04(b) and the rates
     published by each Reference Bank and used for the purpose of determining
     the applicable LIBOR Rate hereunder; and

          (v) if, with respect to any Advance bearing interest at a rate based
     on the LIBOR Rate, any Bank shall


                                      -23-


<PAGE>   25


      notify the Administrative Agent that the LIBOR Rate for any Interest
      Period for such Advance will not adequately reflect the cost to such Bank
      of making, funding or maintaining its portion of such Advance for such
      Interest Period, the Administrative Agent shall forthwith so notify the
      Borrowers and the Banks, whereupon

           (A) each such Bank's portion of each such Advance bearing interest
      at a rate based on the LIBOR Rate will automatically, on the last day of
      the then existing Interest Period therefor, convert into an Advance
      bearing interest at a rate based on the Alternate Base Rate, and

           (B) the obligation of each such Bank to make Advances, or to convert
      Advances into Advances, bearing interest at a rate based on the LIBOR
      Rate shall be suspended until such Bank shall notify the Borrowers and
      the Administrative Agent that the circumstances causing such suspension
      no longer exist.

         (c) In the event that the Administrative Agent or any Bank does not
receive on the due date any sum due under this Agreement or any of the other
Loan Documents in accordance with the terms hereof or thereof, or so long as any
Event of Default has occurred and is continuing, the Borrowers shall pay to the
Administrative Agent and such Banks, as the case may be, on demand in accordance
with Section 2.07 hereof, interest on all unpaid sums, from and including the
due date thereof or the date such Event of Default occurred, whichever is
earlier to but not including the date of actual payment (or date such Event of
Default is cured), at a rate per annum determined by the Administrative Agent
from time to time to be the sum of (a) two per cent (2%) and the Applicable
Margin plus (b) the Applicable Rate. Except as otherwise provided in the
following subsection (d), any such interest which is not paid when due shall be
compounded at the end of each Interest Period (both before and after any notice
of demand) by the Administrative Agent on behalf of the Banks under this
Agreement.

         (d) Notwithstanding any provision contained in any of the Loan
Documents, none of the Banks, the Letter of Credit Agent nor the Administrative
Agent shall ever be entitled to receive, collect, or apply, as interest on the
Obligations, any amount in excess of the maximum rate of interest permitted to
be charged by Applicable Law. In the event any Bank, the Letter of Credit Agent
or the Administrative Agent ever receives, collects, or applies as interest, any
such excess, such amount which would be excessive interest shall be applied to
the reduction of the Obligations then outstanding. If the Obligations then
outstanding are paid in full, any remaining excess shall forthwith be paid to
the Borrowers. In determining whether or not the interest paid or payable, under
any specific contingency, exceeds the highest lawful rate, the Borrowers and any
Bank, the Letter of Credit Agent or the Administrative Agent, as the case



                                     - 24 -
<PAGE>   26


may be, shall, to the maximum extent permitted under Applicable Law, (i)
characterize any non-principal payment as an expense, fee or premium rather
than as interest, (ii) exclude any voluntary prepayments and the effects
thereof, and (iii) spread the total amount of interest throughout the entire
contemplated term of the Obligations so that the interest rate is uniform
throughout the entire term of the Obligations.

     SECTION 1.025 Prepayments. (a) Upon at least four Business Days' notice to
the Administrative Agent received by 10:00 A.M. New York time, the Borrowers may
prepay, subject to payment of Breakage Costs, if any, incurred by the Banks, the
outstanding amount of each Advance for a Facility, in whole or in part, on the
last day of any Interest Period for each such Advance or part thereof, with
accrued interest to the date of such prepayment on the amount prepaid, provided
that no such partial prepayment shall be in a principal amount of less than Two
Hundred Fifty Thousand Dollars ($250,000) and be in integral multiples of One
Hundred Thousand Dollars ($100,000) in addition to such minimum amount. The
Administrative Agent promptly shall give the Banks a copy of each such notice
received from the Borrowers. Optional repayments shall be applied to completely
repay the Facilities in the following order: Facility A, then Facility B, then
Facility F, and then, to the extent that the Borrowers have terminated the
Commitment under Facility A, to be deposited in the Cash Collateral Account as
security for Facility C and Facility D. Optional prepayments in respect of each
Facility shall be applied to such Facility (i) first to the next scheduled
payment of principal, (ii) then to the final payment due on the Maturity Date
and (iii) finally pro rata over the remaining scheduled principal payments.
Prepayments shall be applied pro rata to all Banks' Advances under the
respective Facility. If Facility B is prepaid, no part thereof may be
reborrowed. If Facility F is prepaid, amounts may be reborrowed to the extent of
the Available Commitment described in Exhibit K hereto.

     (b) The Borrowers shall prepay the Advances as follows:

           (i)  an amount equal to one hundred percent (100%) of all proceeds
      (net of Taxes and reasonable expenses in connection with the sale) from
      the sale of any assets by the Borrowers in excess of One Hundred Thousand
      Dollars ($100,000) in any one transaction or Five Hundred Thousand
      Dollars ($500,000) in any calendar year; such prepayment to be made not
      later than the date of such sale; any such prepayments shall be applied
      ratably among all Advances of the Banks as follows (v) first, to repay to
      the last installment due in respect of Advances for Facility B on the
      Maturity Date and then pro rata over the remaining Principal Payment
      Dates for Facility B, (w) second, to reduce Advances under Facility A to
      the last installment due in respect of Advances (x) third, for Facility F
      on the Maturity Date and


                                      -25-

<PAGE>   27


      then pro rata over the remaining Principal Payment Dates for Facility F,
      fourth, and (y) to the extent that the Borrowers have terminated the
      Commitment under Facility A, to be deposited to the Cash Collateral
      Account as security for Facility C and Facility D; and

           (ii) an amount as shall be necessary to comply with the provisions
      of Section 5.01(e); such prepayment to be applied first to Advances
      outstanding in respect of Facility B, and then to Advances outstanding in
      respect of Facility A and Facility F in inverse order of maturity and
      ratably among the Banks.

         (c) If it shall become unlawful for any Bank to continue to fund or
maintain any Advance or to perform its obligations hereunder, such Bank shall
notify and consult with the Borrowers and the Administrative Agent before making
any demand under this Section 2.05(c), and such Bank and the Administrative
Agent shall use all reasonable efforts to change its lending office or take
other measures so that it can perform its obligations hereunder; provided that
neither such Bank nor the Administrative Agent shall be obligated to change its
lending office or take any other measures if in its sole reasonable judgment it
would be disadvantageous to do so. If such Bank does not change its lending
office because it determines in its sole reasonable judgment that it is
disadvantageous to do so or because such change would not render such Advance
lawful, then such Bank shall notify the Administrative Agent and the Borrowers,
as the case may be, and shall make an Advance, and the Borrowers shall borrow
such Advance, at a rate based on the Alternate Base Rate in an amount equal to
the amount of the Advance currently outstanding and made by such Bank to the
Borrowers, if in the sole reasonable judgment of such Bank such Advance can
lawfully be extended at a rate based on the Alternate Base Rate. Simultaneously
with making such Advance at a rate based on the Alternate Base Rate, the Advance
then outstanding made available by such Bank to the Borrowers shall be repaid
with accrued interest thereon to the date of payment. If any Bank makes an
Advance at a rate based on the Alternate Base Rate to the Borrowers pursuant to
this Section, the Borrowers may prepay such Advance made by such Bank, without
penalty, at any time upon five Business Days notice. If despite such Bank's
compliance with the preceding provisions of this Section 2.05(c), or if the
Borrowers shall refuse to borrow an Advance at a rate based on the Alternate
Base Rate as herein provided, and if it shall become unlawful for any Bank to
fund or maintain any Advance or perform its obligations hereunder, upon demand
by such Bank, the Borrowers shall prepay in full the outstanding Advance made by
such Bank, with accrued interest thereon and all other amounts payable by the
Borrowers hereunder, and upon such demand or any notice of prepayment the
obligation of such Bank to make any Advance to the Borrowers shall terminate.

     (d) (1)  If a Total Loss occurs, the Borrowers shall give prompt written
notice to the Administrative Agent of such Total Loss.  Unless the Borrowers
provide a Substitute Vessel under Section 2.05 (d)(3) and to the extent
necessary to comply with Section 5.01(e), not more than 120 days (the "Loss
Termination Date") after the date such Total Loss occurred, the Borrowers shall
pay to or to the order of the Administrative Agent, the sum of (a) the product
of the then outstanding principal amount of the Notes multiplied by a fraction,
in which the numerator is the Fair Market Value of the Vessel subject to the
Total Loss as determined by the last appraisal obtained pursuant to Section
1.03 prior to such Total Loss and the denominator is the aggregate Fair Market
Value similarly determined for all Mortgaged Vessels immediately prior to such
Total Loss, (b) accrued and unpaid interest on the Notes being prepaid through
the Loss Termination Date, (c) an amount equal to all out-of-pocket third party
expenses (including legal and investigatory fees) incurred by and not otherwise
reimbursed to, the Administrative Agent or the Banks in connection with the
occurrence of the Total Loss, as set forth in a certificate of the
Administrative Agent to be delivered to the Borrowers not less than five
Business Days prior to the Loss Termination Date, and (d) any other amounts
which have become due and payable under the Loan Documents but shall not have
been paid prior to the Loss Termination Date minus the sum of all insurance
proceeds actually received by the Administrative Agent in connection with such
Total Loss.  All prepayments received after such Total Loss shall be applied as
provided in Section 6.02 hereunder.

     (2)  If a Total Loss occurs, the Borrowers, not less than 30 days before
the Loss Termination Date, may notify the Administrative Agent of their
intention to replace the Vessel constituting the Total Loss with a substitute
vessel (the "Substitute Vessel").  Prior to or at the time of any substitution
under this Section, the Borrowers will at their own expense and cost furnish
the Administrative Agent with a satisfactory appraisal of the proposed
Substitute Vessel.  If the Administrative Agent and the Banks in their
reasonable discretion, have agreed to permit the substitution, the Borrowers at
their own cost and expense shall cause a Mortgage covering the Substitute
Vessel to be duly executed and recorded at the Home Port of the Substitute
Vessel and shall make such amendments to the Loan Documents and Security
Documents as the Administrative Agent shall deem necessary or desirable to
reflect such substitution.

     (3)  If the Fair Market Value of the Substitute Vessel is less than the
Fair Market Value of the Vessel which constituted such Total Loss, the
Borrowers may grant the Administrative Agent on behalf of the Banks a perfected
first priority security interest in additional collateral satisfactory to the
Administrative Agent and the Banks, in their sole discretion, the Fair Market
Value of which (as determined by an appraisal of the type described in Section
1.03) shall be added



                                      -27-
<PAGE>   29


to the Fair Market Value of the Substitute Vessel for the purposes of complying
with Section 5.01(e)(ii).

     (4)  If the Banks, in their sole discretion, permit the sale or other such
disposition of any Mortgaged Vessel and if as a result of such sale or
disposition the Borrowers no longer comply with Section 5.01(e)(ii), then all
proceeds of such sale or disposition shall be paid to the Administrative Agent
and the Administrative Agent shall apply all such proceeds to the payment of
all such amounts payable as if in respect of a Total Loss of such Vessel
pursuant to subsection (d)(1) above.

     (e) If at any time the Borrowers shall, or may reasonably be expected to,
be required to deduct and withhold, or indemnify any Bank with respect to, any
Taxes (as defined in Section 2.09) (in each case, as evidenced by an opinion
reasonably satisfactory in form and substance to the Borrowers, the
Administrative Agent, the Letter of Credit Agent and the Banks from independent
tax counsel reasonably satisfactory to the Borrowers, the Administrative Agent,
the Letter of Credit Agent and the Banks) the Borrowers, upon at least four
Business Days' notice to the Administrative Agent and the Banks, may prepay at
any time, pro rata, the outstanding principal amount of each Advance, in whole
or in part, together with accrued interest to the date of prepayment on the
amount prepaid and all other amounts, including without limitation Breakage
Costs, then payable to the Banks by the Borrowers; provided that, if such Taxes
relate to payments to fewer than all the Banks (the "Affected Banks"), the
Borrowers, upon at least four Business Days' notice to the Administrative Agent
and the Affected Banks, may prepay, in whole or in part, pro rata (except as
set forth in the following provision), the outstanding principal amount of
Advances made by the Affected Banks, with accrued interest thereon and all
other amounts payable to the Affected Banks by the Borrowers (without
prepayment any portion of any Advance made by any Bank that is not any Affected
Bank); provided further, that if the rate of Taxes with respect to any Affected
Bank is higher than with respect to another Affected Bank, the Borrowers may
prepay any portion of the Advance made by the former Affected Bank without
prepaying any portion of the Advance made by the latter Affected Bank.  The
Administrative Agent shall give prompt written notice to the Banks of any
prepayments made under this paragraph (e).  No amount of principal paid or
prepaid, as the case may be, may be reborrowed except as otherwise explicitly
provided in this Agreement.  Prepayments shall be applied first to outstanding
interest and Breakage Costs, if any, and then to installments of outstanding
principal in inverse order of maturity, except as otherwise expressly provided
herein.

     SECTION 1.026 Increased Costs; Additional Interest. (a) If on or after the
Closing Date due to (i) the introduction of or any change (including, without
limitation, any change by way of imposition or increase of reserve or capital
adequacy requirements) in, or in the interpretation of, any law or


                                      -28-

<PAGE>   30


regulation, or (ii) the compliance by any Bank with any guideline or request
(including, with respect to reserve and capital adequacy requirements, those
Applicable Laws, policies, guidelines and directives and interpretations in
effect on the Closing Date) from any central bank or other governmental
authority, whether or not having the force of law, there shall be any increase
in the cost to, or reduction in the return on capital of any Bank in
consequence of, any Bank agreeing to make or making, funding or maintaining an
Advance, then the Borrowers shall from time to time, upon demand by such Bank,
pay to such Bank additional amounts sufficient to indemnify such Bank against
such increased cost (without duplication of any amounts pursuant to Section
2.06(b) herein).

     (b) If any Bank shall determine that reserves under Regulation D of the
Board of Governors of the Federal Reserve System, as in effect from time to
time, are required to be maintained by it in respect of, or a portion of its
costs of maintaining reserves under Regulation D is properly attributable to,
one or more of its Advances, such Bank shall, subject to the provisions of
Section 2.06(d) below, give notice to the Borrowers, together with a
certificate as described below in Section 2.06(c) and the Borrowers, as the
case may be, shall pay to such Bank additional interest on the unpaid principal
amount of each such Advance, payable on the same day or days on which interest
is payable on such Advance, at an interest rate per annum equal at all times
during each Interest Period for such Advance to the excess of (i) the
Applicable Margin plus the rate obtained by dividing the LIBOR Rate for such
Interest Period by a percentage equal to 100% minus the Reserve Percentage
(defined in the next sentence), if any, applicable during such Interest Period
over (ii) the LIBOR Rate for such Interest Period.  The "Reserve Percentage"
for any such period, with respect to any Advance, means the reserve percentage
applicable thereto under regulations issued from time to time by the Board of
Governors of the Federal Reserve System (or any successor) for determining the
maximum reserve requirement (including, but not limited to, any emergency,
supplemental or other marginal reserve requirement) for a member bank of the
Federal Reserve System in New York City with respect to (i) liabilities or
assets consisting of or including eurocurrency liabilities, as defined in
Regulation D of the Board of Governors of the Federal Reserve System, as in
effect from time to time, and having a term equal to any such period, or (ii)
any other category of liabilities which includes deposits by reference to which
the interest rate on such Advance is determined and which have a term equal to
any such period.

     (c) If any Bank determines that compliance with any law or regulation or
any guideline or request from any central bank or other governmental authority
(whether or not having the force of law) affects or would affect the amount of
capital required or expected to be maintained by the Bank or any corporation
controlling the Bank and that the amount of such capital is increased by or
based upon the existence of the Bank's



                                      -29-

<PAGE>   31


commitment to lend hereunder and other commitments of this type, then, upon
demand by the Bank made in accordance with the provisions of Section 2.06(d)
hereof, the Borrowers shall immediately pay to the Bank, from time to time as
specified by the Bank in a certificate delivered to the Borrowers, additional
amounts sufficient to compensate the Bank or such corporation in the light of
such circumstance, to the extent that the Bank reasonably determines such
increase in capital to be allocable to the existence of the Bank's commitment
to lend hereunder.  A certificate as to the amount of any such increased cost,
increased interest or reduced return under this Section 2.06, submitted to the
Borrowers and the Administrative Agent by such Bank, setting forth calculations
in reasonable detail shall be conclusive and binding for all purposes, absent
manifest error.

     (d) Before making any demand under this Section 2.06, the Bank shall
consult with the Borrowers and the Administrative Agent and such Bank and the
Administrative Agent shall designate as to itself a different lending office or
take such other measures if such designation or measures would avoid the need
for, or reduce the amount of such increased cost or interest, provided that
neither such Bank nor the Administrative Agent shall be obliged to change its
lending office or take any other measures if in its sole reasonable judgment it
would be disadvantageous to do so.

     (e) The Borrowers may, upon at least four Business Days' notice to the
Administrative Agent and any such Bank requesting payment of any amounts
pursuant to this Section 2.06, prepay the outstanding principal amount of each
Advance together with accrued interest to the date of prepayment on the amount
prepaid and all other amounts, including without limitation Breakage Costs, if
any, then payable to such Bank by the Borrowers.

     SECTION 1.027 Letter of Credit. (a) Subject to the terms and conditions of
this Agreement, the Letter of Credit Agent, in reliance on the Agreements of the
Banks set forth in Section 2.07(f), agrees to issue:

           (i) a Letter of Credit in respect of Facility C for the account of
      the Borrowers on the Closing Date and on each Letter of Credit Renewal
      Date in such form as may be approved from time to time by the Letter of
      Credit Agent; and

           (ii) one or more Letters of Credit in respect of Facility D for the
      account of the Borrowers on a Letter of Credit Closing Date and on each
      Letter of Credit Renewal Date in such form as may be approved from time
      to time by the Letter of Credit Agent.

Facility D shall not exceed Six Million United States Dollars (US $6,000,000)
at any one time.  Subject to the Six Million United States Dollar limit imposed
in the preceding sentence, Letters of Credit in respect of Facility D may be
issued only to the extent that the aggregate stated amount (including
unreimbursed Letter of Credit Obligations, if any) of such Letters of Credit
shall be equal or less than (x) the sum of the aggregate amounts available to
be drawn in respect of Facility A minus (y) the sum of the outstanding Advances
in respect of Facility A.  The amounts that may be drawn and are permitted to
be outstanding in respect of Facility A are reduced by the aggregate stated
amounts of all Letters of Credit issued and outstanding pursuant to Facility D.
The aggregate stated amounts of all Letters of Credit issued and outstanding
under Facility D shall not include any expired or canceled Letters of Credit
which have been issued under Facility D unless the expired or canceled Letters
of Credit constitute Unreimbursed Letter of Credit Obligations.

     (c) Any Letter of Credit shall be subject to the Uniform Customs and, to
the extent not inconsistent, with the laws of the state in which the principal
office of the Letter of Credit Agent is located.

     (d) The Letter of Credit Agent shall not be obligated to issue any Letter
of Credit hereunder if (x) such issuance would conflict with, or cause the
Letter of Credit Agent to exceed any limits imposed by Applicable Law; or (y)
if the Letter of Credit by its terms, expires after the applicable Maturity
Date.

     (e) The Borrowers may request that the Letter of Credit Agent issue a
Letter of Credit by delivering to the Letter of Credit Agent and the
Administrative Agent an Application completed to the satisfaction of the Letter
of Credit Agent, the certificate referred to in Section 3.02 dated the date of
such Application and such other certificates, documents and other papers and
information as may be customary for a letter of credit of the kind being
requested and as the Letter of Credit Agent may



                                      -31-

<PAGE>   33


reasonably request.  Upon receipt of the Application, and the certificates,
documents and other papers and information delivered to it in connection
therewith in accordance with its customary procedures, the Letter of Credit
Agent shall promptly issue any Letter of Credit requested thereby issuing the
original of such Letter of Credit to the beneficiary thereof or as otherwise
may be agreed by the Letter of Credit Agent and the Borrowers.

     (f) (i) Effective on the date of issuance of a Letter of Credit, the
Letter of Credit Agent irrevocably agrees to grant and hereby grants to each
Bank, and each Bank irrevocably agrees to accept and purchase and thereby
accepts and purchases from the Letter of Credit Agent, on the terms and
conditions hereinafter stated, for such Bank's own account and risk an
undivided participation equal to such Bank's Percentage Interest in the
Facility relating to such Letter of Credit and in the Letter of Credit Agent's
obligations and rights under such Letter of Credit issued by the Letter of
Credit Agent and the amount of each draft paid by the Letter of Credit Agent
thereunder.  Each Bank unconditionally and irrevocably agrees with the Letter
of Credit Agent that, if a draft is paid whether prior to the Maturity Date or
after the Maturity Date, under any Letter of Credit for which the Letter of
Credit Agent is not reimbursed in full by the Borrowers in accordance with the
terms of this Agreement, each Bank shall pay to the Letter of Credit Agent upon
demand at the Lending Office an amount equal to such Bank's Percentage Interest
of the unreimbursed amount of such draft or any part thereof.  The Banks'
obligations hereunder shall be absolute without regard to the occurrence of any
Default or Event of Default, the lapsing of Maturity Date or the occurrence of
any other condition precedent whatsoever.

     (ii) If the Letter of Credit Agent does not receive any payment from a
Bank required under this section on the date such payment is due, such Bank
shall pay to the Letter of Credit Agent, on demand, an amount equal to the
product of (x) such amount, and (y) the daily average Federal Funds Rate during
the period from and including the date such payment is required to the date on
which such payment is immediately available to the Letter of Credit Agent
multiplied by (z) a fraction the numerator of which is the number of days that
have elapsed during such period and the denominator of which is 360.  If any
unreimbursed amount required to be paid by any Bank pursuant to this Section is
not made available to the Letter of Credit Agent by such Bank within three
Business Days after the date such payment is due, the Letter of Credit Agent
shall be entitled to recover from such Bank, on demand, such amount with
interest thereon calculated from such due date at the rate per annum applicable
to Base Rate Advances hereunder.  A certificate of the Letter of Credit Agent
submitted to any Bank with respect to any amounts owing under this Section
shall be conclusive in the absence of manifest error.



                                      -32-

<PAGE>   34



     (iii)  If, at any time after the Letter of Credit Agent has paid a draft
under a Letter of Credit and has received from any Bank its pro rata share of
such payment in accordance with this Section, the Letter of Credit Agent
receives any payment (excluding any fees and other amounts paid pursuant to
Section 2.07(g)) related to such Letter of Credit (whether directly from the
Borrowers or otherwise, including proceeds of collateral applied thereto by the
Administrative Agent), or any payment of interest on account thereof, then the
Letter of Credit Agent shall pay to the Administrative Agent, for the account
of such Bank, its pro rata share thereof; provided, however, that if any such
payment received by the Letter of Credit Agent is required to be returned by
the Letter of Credit Agent, such Bank shall return to the Administrative Agent
for the account of the Letter of Credit Agent, the portion thereof previously
distributed to such Bank.

     (g) The Letter of Credit Agent shall notify the Borrowers of the date and
amount of any draft presented under a Letter of Credit.  The Borrowers agree to
reimburse the Letter of Credit Agent on each such date for all amounts paid by
the Letter of Credit Agent for the account of (i) such drafts so paid and (ii)
any Taxes, fees, charges or other costs or expenses incurred by the Letter of
Credit Agent in connection with such payment.  Each payment shall be made to
the Letter of Credit Agent at its address for notices specified herein and in
lawful money of the United States and immediately available funds.  Interest
shall be payable on any or all amounts remaining unpaid by the Borrowers under
this subsection from the date such amounts become payable until payment in full
at the rate which will be payable on Base Rate Advances at such time.

     (h) Each of the Borrowers' obligations under this Section shall be
absolute and unconditional under any and all circumstances and without setoff,
counterclaim or defense to payment which any Borrower may have or have had
against the Letter of Credit Agent or any beneficiary of a Letter of Credit.
Each of the Borrowers also agrees with the Letter of Credit Agent that the
Letter of Credit Agent shall not be responsible for, and that the Borrowers'
obligations under this Section shall not be affected by, among other things,
the validity or genuineness of documents or any endorsements thereon, even
though such documents shall in fact prove to be invalid, fraudulent or forged
or any dispute between or among the Borrowers and any beneficiary of a Letter
of Credit or any other party to which such Letter of Credit may be transferred
or any claims whatsoever of the Borrowers against any beneficiary of a Letter
of Credit or any such transferee.  The Letter of Credit Agent shall not be
liable for any error, omission, interruption or delay in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with a
Letter of Credit, except for errors or omissions caused by the Letter of Credit
Agent's gross negligence or willful misconduct.  The Borrowers agree that any
action taken or omitted by the Letter of Credit Agent in


                                      -33-

<PAGE>   35


connection with a Letter of Credit or the related drafts or documents, if done
in the absence of gross negligence or willful misconduct and in accordance with
the standards of care specified in the Uniform Commercial Code of the state in
which the principal office of the Letter of Credit Agent is located, shall be
binding on the Borrowers and shall not result in any liability of the Letter of
Credit Agent to the Borrowers.

     (i) If any draft shall be presented for payment of a Letter of Credit, the
Letter of Credit Agent shall promptly notify the Borrowers, the Banks and the
Administrative Agent of the date and amount thereof.  The responsibility of the
Letter of Credit Agent to the Borrowers in connection with any draft presented
for payment under a Letter of Credit shall, in addition to any payment
obligation expressly provided in a Letter of Credit, be limited to determining
that the documents (including each draft delivered under a Letter of Credit in
connection with such presentment) are in conformity on their face with such
Letter of Credit.

     (j) To the extent that any provision of the Application, including any
reimbursement provisions contained therein, related to a Letter of Credit is
inconsistent with the provisions of this Section, the provisions of this
Section shall prevail.

     SECTION 1.028 Payments and Computations.  (a)  The Borrowers shall make 
each payment hereunder and under any instrument and other Loan Document
delivered hereunder (except as otherwise provided in any such instrument) due
to any Bank or the Administrative Agent not later than 12:00 noon New York City
time on the date when due, without set off or counterclaim, in lawful and
freely transferable United States Dollars to the Administrative Agent at the
Lending Office for the account of the Administrative Agent in same day funds. 
The Administrative Agent shall promptly disburse to the Banks funds of such
type as it shall have received in the manner provided by this Agreement.

     (b) The Borrowers hereby authorize the Administrative Agent and each Bank,
if and to the extent payment is not made when due hereunder or under any
instrument delivered hereunder and the Borrowers have been given, or otherwise
have, notice thereof, to charge from time to time against any or all of the
Borrowers' accounts with the Administrative Agent or the Banks, as the case may
be, any amounts so due, provided that, so long as a Default or Event of Default
has occurred and is continuing, no such notice to the Borrowers shall be
required.  The Borrowers further agree that not later than 12:00 noon (New York
City time) on each day on which a payment is due hereunder with respect to the
Advance or under any Note, it will have in its account maintained with the
Administrative Agent in New York City a credit balance at least equal to the
total amount so due on such day.



                                      -34-

<PAGE>   36



     (c) All computations of interest and fees shall be made by the
Administrative Agent, the Letter of Credit Agent and the Banks on the basis of
a year of 360 days for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest or fee
is payable except that interest in respect of the Base Rate shall be calculated
on the basis of actual days elapsed over a 365/366 day year.

     (d) Whenever any payment to be made hereunder or under the Loan Documents
shall be stated to be due, or the Interest Payment Date would otherwise occur
on a day other than a Business Day, such payment shall be made, and the
Interest Payment Date shall occur, on the next succeeding Business Day, and any
such extension of time shall in all cases be taken into account in the
computation of payment of interest due hereunder or otherwise; provided,
however, if such extension would extend the Maturity Date or would cause such
payment to be made, or, in respect of an Interest Payment Date for any Advance
bearing interest at a rate based on the LIBOR Rate, to occur in a new calendar
month, such payment shall be made, and the Interest Payment Date shall occur on
the preceding Business Day.

     (e) All parties to this Agreement acknowledge and agree that the
Obligations shall be automatically decreased (without any further action of any
Person being required) to the extent of any amounts received pursuant to
Section 2.08(a) hereof by the Administrative Agent, the Mortgagee or any of the
Banks under the Security Documents, as the case may be, which amounts the
Administrative Agent or the Banks, as the case may be, may freely apply or
cause to be applied to the repayment of the Obligations as provided in the Loan
Documents.  Except as otherwise expressly provided in the preceding sentence,
the Security Documents shall not in any way negate or adversely affect the
liabilities and Obligations which the Borrowers and any other party have under
this Agreement and the other Loan Documents to the Banks, the Letter of Credit
Agent or the Administrative Agent.

     SECTION 1.029 Taxes. (a) Any and all payments made by the Borrowers under
this Agreement shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future Taxes, except as
required by Applicable Law. If any Taxes are required by Applicable Law to be
deducted or withheld from any payment hereunder to the Administrative Agent, the
Letter of Credit Agent or any Bank, the Borrowers shall (i) promptly notify the
Administrative Agent, the Letter of Credit Agent or such Bank, as applicable, of
such requirement, (ii) deduct or withhold the full amount of such Taxes in a
timely manner and pay such Taxes in a timely manner to the appropriate
authorities, (iii) promptly forward to the Administrative Agent for its own
account, the Letter of Credit Agent for its own account or the account of such
Bank, as applicable, an official receipt or certified copy thereof or other
documentary evidence


                                      -35-

<PAGE>   37


satisfactory to the Administrative Agent, Letter of Credit Agent or such Bank
evidencing such payment and (iv) except in the case of Bank Taxes, pay such
additional amounts so that the amount received by the Administrative Agent, the
Letter of Credit Agent or such Bank with respect to such payment, after the
payment of such Taxes (including any Taxes on such additional amounts), equals
the full amount such Administrative Agent, the Letter of Credit Agent or such
Bank would have otherwise received with respect to such payment had no
deduction or withholding been required.  Further, if any Taxes (other than Bank
Taxes) are asserted directly against the Administrative Agent, Letter of Credit
Agent or any Bank with respect to any payment hereunder to the Administrative
Agent, the Letter of Credit Agent or such Bank, the Administrative Agent, the
Letter of Credit Agent or such Bank may pay such Taxes and the Borrower shall
promptly pay such additional amounts (including any penalties, interest or
expenses) so that the amount received by the Administrative Agent, Letter of
Credit Agent or such Bank, after the payment of such Taxes (including any Taxes
on such additional amounts), equals the full amount the Administrative Agent,
the Letter of Credit Agent or such Bank would have otherwise received had no
such Taxes been asserted.  If the Borrower fails to pay to the appropriate
authority any Taxes when due or fails to remit to the Administrative Agent, the
Letter of Credit Agent or such Bank, as applicable, the required receipts
evidencing payment of such Taxes, the Borrowers shall indemnify the
Administrative Agent, the Letter of Credit Agent or such Bank for any Taxes
that may become payable as a result of such failure.

     (b)  The Borrowers shall not be required to pay any additional amounts to
the Administrative Agent, Letter of Credit Agent or any Bank in respect of
United States federal withholding taxes pursuant to Section 2.09(a) above if
the obligation to pay such additional amounts would not have arisen but for a
failure by such Bank to comply with the provisions of Section 2.09(c).  In the
event the Borrowers have actual knowledge that they are required to, or there
arises, in the Borrowers' reasonable opinion, a substantial likelihood that the
Borrowers will be required to, pay an increased amount or otherwise indemnify
the Administrative Agent, the Letter of Credit Agent or any Bank for or on
account of any Taxes pursuant to Section 2.09(a), the Borrowers shall promptly
notify the Administrative Agent, the Letter of Credit Agent and such Bank of
the nature of such Taxes and shall furnish such information to the
Administrative Agent, the Letter of Credit Agent and such Bank as the
Administrative Agent, the Letter of Credit Agent or such Bank may reasonably
request.  In the event the Borrowers provide the notice described in the
preceding sentence, the Borrowers, the Administrative Agent, the Letter of
Credit Agent and each relevant Bank shall consult in good faith to determine
what may be required to avoid or reduce such Taxes and shall each use
reasonable efforts to avoid or reduce such Taxes (so long as such efforts
result in no incremental costs to the Administrative Agent, the Letter of
Credit Agent or such Bank, do not modify the terms of repayment



                                      -36-

of the Loans or materially disadvantage the Administrative Agent, the Letter of
Credit Agent or such Bank).

     (c)  Prior to the first payment to the Administrative Agent, the Letter of
Credit Agent or any Bank under this Agreement, each Bank that is not
incorporated under the laws of the United States, any State thereof or the
District of Columbia shall deliver to the Borrowers and the Administrative
Agent (i) two duly completed copies of United States Internal Revenue Service
Form 1001 or Form 4224 (or applicable successor form and any related forms as
may from time to time be adopted to document a claim to which such form
relates) and (ii) a duly completed copy of United States Internal Revenue
Service Form W-8 or W-9 (or applicable successor form and any related forms as
may from time to time be adopted to document a claim to which such form
relates).  Such Bank shall certify that (x) in the case of any form provided
pursuant to clause (i) of the preceding sentence it is entitled to receive
payments hereunder without deduction or withholding of any United States
federal income taxes and (y) in the case of any form provided pursuant to
clause (ii) of the preceding sentence it is entitled to receive payments
hereunder without deduction or withholding of any United States federal backup
withholding taxes.  Each such Bank also agrees to deliver further copies of
said Form 1001, 4224, W-8 or W-9 (or applicable successor form and any related
forms as may from time to time be adopted to document a claim to which such
form relates), and any related certification as described in the preceding
sentence, as the case may be, (i) on or before the date that any such form
previously provided expires or becomes obsolete, (ii) after the occurrence of
any event requiring a change in the most recent form previously provided
unless, in any case, an event (including, without limitation, any change in a
treaty, law or regulation) has occurred prior to the date on which delivery
would otherwise be required that renders all such forms inapplicable or that
would prevent such Bank from duly completing and delivering any such form with
respect to it and such Bank so advises the Borrowers and the Administrative
Agent and the Letter of Credit Agent and (iii) upon reasonable request of the
Borrower.

     (d) The Borrowers will indemnify the Administrative Agent and each Bank
for the full amount of Taxes (other than Bank Taxes) payable by the
Administrative Agent or such Bank, as the case may be, on any and all payments
made hereunder or on any instrument delivered hereunder and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto, whether or not such Taxes were correctly or legally asserted.  This
indemnification shall be made within 30 days from the date the Administrative
Agent or the Bank, as the case may be, makes written demand therefor with
appropriate supporting documentation.  The Administrative Agent or the Bank, as
the case may be, to the extent practicable, shall notify the Borrowers before
paying, or requiring the Borrowers to pay, any such Tax.


                                      -37-

<PAGE>   39



     (e) Within 30 days after the date of any payment of Taxes, the Borrowers
will deliver to the Administrative Agent and each Bank satisfactory evidence of
payment thereof.  If no Taxes are payable in respect of any payment, the
Borrowers will, at the reasonable request of the Administrative Agent on behalf
of any Bank, as the case may be, deliver to the Administrative Agent a
certificate from each appropriate taxing authority or any political subdivision
thereof, or an opinion of counsel acceptable to the Administrative Agent, in a
form reasonably acceptable to the Administrative Agent, stating, or other
satisfactory evidence, that such payment is exempt from or not subject to
Taxes.

     (f) Without prejudice to the survival of any other agreement of the
Borrowers hereunder, the agreements and obligations of the Borrowers contained
in subsections (a) through (f) of this Section 2.09 shall survive the payment
in full of the Obligations and the expiry of the Loan Documents.

     SECTION 2.10 Fees. (a) On the Effective Date, the Borrowers shall pay
solely for the account of each Bank on the Effective Date $[ ] representing the
aggregate amount of any Commitment Fees and other fees owed the Banks accruing
prior to the Effective Date. The Borrowers shall pay the Administrative Agent,
solely for the account of each Bank, on the date which is three months from the
Effective Date and quarterly thereafter, a non-refundable commitment fee (as to
each Bank, its "Commitment Fee") of one-half of one percent (1/2%) per annum of
each such Bank's respective Commitment daily in respect of the unused portion of
the Bank's Commitment. The Commitment Fee shall be calculated quarterly in
arrears from the Effective Date. Notwithstanding anything to the contrary
contained in this Agreement or in any other agreement, each Bank's Commitment
Fee and the fees described in the first sentence of this subsection shall be
solely for the account of such Bank.

     (b) The Borrowers shall pay the Co-Agents for their own accounts on the
Closing Date, and not later than the anniversary of such date of each year
thereafter so long as any amount payable by the Borrowers hereunder remains
outstanding, an annual agency fee in an amount mutually agreed between them.

     (c) (i)  The Borrower shall pay a letter of credit fee to the
Administrative Agent for the account of the Letter of Credit Agent.  Upon
receipt of the letter of credit fee, the Letter of Credit Agent shall
distribute such fee to the Banks pro rata and without deduction.  The letter of
credit fee shall be at the per annum rate equal to the Applicable Margin for
the LIBOR Rate (as determined in Section 2.04(b)(iii) on the average daily
aggregate amount available to be drawn under the Letter of Credit for the
period for which the fee is calculated.  Such fee shall accrue from the date on
which the Letter of Credit is issued and shall be payable quarterly in arrears
commencing on December 31



                                      -38-

<PAGE>   40


and quarterly thereafter until the termination of the Letter of Credit.

         (ii) In addition to the foregoing fees and commissions, the Borrowers
shall pay or reimburse the Letter of Credit Agent for such normal and customary
costs and expenses as are incurred or charged by the Letter of Credit Agent in
issuing, effecting payment under or amending any Letter of Credit.

     (d)  On the Agreement Date, the Borrowers shall pay to the Administrative
Agent the Amendment and Restatement Fees of Two Hundred Ninety Seven Thousand
Dollars (US$297,000) and New Money Fees of Two Hundred Thousand Five Hundred
Dollars (US$200,500) which Amendment and Restatement Fees and New Money Fees
shall be shared by the Banks according to their respective Percentage
Interests.

     SECTION 2.11 Optional Reduction. Upon at least four Business Days' notice,
the Borrowers shall have the right to terminate, in whole or in part, the
undrawn portion of Facility A. Any such partial terminations shall be in a
minimum amount of Two Hundred Fifty Thousand Dollars (US$250,000) and integral
multiples thereof. Reductions shall be applied ratably among the Banks'
Commitments. Once terminated, the Borrowers shall have no right to reinstate
such terminated Commitment.

          the assumptions underlying such plan in reasonable detail, certified

          ERISA the Borrowers shall deliver to the Administrative Agent copies
          of all reports and notices which it or any of its Subsidiaries files
          under ERISA; and

               (ix) From time to time on request, the Borrowers shall furnish
          the Administrative Agent, the Letter of Credit Agent and the Banks

</TABLE>


               (v) Notwithstanding the foregoing, for the period from the IPO
          Date until the first day of the last quarter following the IPO Date,
          all calculations made under this Section 5.01(d) shall be made using
          Hvide's Pro Forma Consolidated Historical Financial Statements as
          presented in the S-1 giving effect to the proposed Second Offering and
          Acquisitions. Thereafter, the Administrative Agent shall use the
          Borrowers' most recent quarterly financial statements for purposes of
          determining whether the foregoing tests have been met.

                 (e)      Collateral Maintenance and Valuation.  (i)  The
Borrowers shall ensure that at all times on and after the first Drawdown Date
the aggregate amount of unpaid principal in respect of Facilities A, B, and F
and the undrawn amounts of any Letters of Credit, issued in respect of
Facilities C and D and Unreimbursed Letter of Credit Obligations ("Total
Outstandings") will be less than the sum of (1) 70% of the Aggregate Fair
Market Value of all Mortgaged Vessels (provided that as to the SEABULK AMERICA,
the value for such Vessel shall not be greater than the maximum amount of the
Mortgage on such Vessel), (2) 70% of all Eligible Receivables and (3) other
such unencumbered material assets reasonably acceptable to the Banks and
pledged to the Banks on a first priority basis as security at such advance
rates as shall be determined reasonably by the Banks (collectively the "Pledged
Collateral").  At any time the Borrowers fail to satisfy the test prescribed in
the preceding sentence, the Borrowers will promptly either (a) provide
additional collateral reasonably acceptable to the Banks or (b) make a
mandatory prepayment in



 
                                      -53-
<PAGE>   55

respect of Facilities A, B, or F or cause any Letter of Credit to be reduced or
terminated in the case of Facilities C and D sufficient to comply with the test
in the preceding sentence.

     (ii) For purposes of covenant testing the Fair Market Value of each such
Mortgaged Vessel shall be the most recent value determined pursuant to Section
1.03 hereof provided that the value of a Mortgaged Vessel which is a Total Loss
shall be zero unless (a) such Total Loss is covered by valid and effective
uncontested insurance complying with the requirements of the Mortgage for such
Mortgaged Vessel and the Loss Termination Date has not passed; or (b) such Total
Loss has been replaced by a Substitute Vessel pursuant to Section 2.05(d)(2) and
such additional collateral as may be required by Section 2.05(d)(3) hereof and
all of the requirements of the Administrative Agent in connection therewith have
been fulfilled and complied with to the satisfaction of the Administrative
Agent.

     (iii) At any time that the Borrowers demonstrate to the reasonable
satisfaction of the Banks for each fiscal quarter after the Effective Date that
the ratio of Total Outstandings to the Pledged Collateral is less than fifty
percent (50%), the Banks agree that in respect of the then next following
quarter (A) the requirement for a pledge or mortgage on all Vessels acquired
after the Closing Date (except for the Vessels listed in Exhibit L hereto which
are required to be mortgaged) is waived (provided, however, that there shall be
no release of existing Mortgaged Vessels) and (B) the restriction on
contributing Mortgaged Vessels to joint ventures and partnerships will be
relaxed for such next following quarter from two percent (2%) to five percent
(5%). However, if the ratio of Total Outstandings to the Pledged Collateral is
equal to or greater than fifty percent (50%) in successive quarters, the
requirement for a pledge or mortgage on all Vessels acquired after the Closing
Date will be re-imposed and the restriction on future contributions of Mortgaged
Vessels to joint ventures and partnerships will be reduced to two percent (2%).

     (f) Insurance. Each of the Borrowers shall, and shall cause each of its
Subsidiaries to, insure and keep insured, with financially sound and reputable
insurers, so much of its properties, in such amounts and against such risks, as
to all the foregoing, in each case, reasonably satisfactory to the
Administrative Agent on behalf of the Banks and as are usually and customarily
insured by companies engaged in a similar business with respect to properties of
a similar character (other than with respect to Vessels which shall be insured
as provided in the Mortgages).

     (g) Access to Books and Records. Each of the Borrowers shall permit the
Administrative Agent or its authorized representatives, promptly upon request,
to make such inspection, examination, copy and audit of its properties, books,
records and accounts and those of its Subsidiaries as the Administrative





                                      -54-
<PAGE>   56

Agent or its authorized representative may reasonably deem necessary or
appropriate in connection with this Agreement or any of the Loan Documents or
the Acquisition Documents.

     (h) Good Standing. Each of the Borrowers shall remain a corporation or
limited partnership duly organized and in good standing under the laws of its
Incorporation Jurisdiction.

     (i) Keeping of Books and Records. The Borrowers shall keep proper books of
record and accounts, in which full and correct entries shall be made of all
financial transactions and the assets and business of the Borrowers and its
Subsidiaries, respectively, in accordance with GAAP consistently applied, or as
otherwise required by applicable rules and regulations of any governmental
agency or regulatory authority having jurisdiction over the Borrowers and its
Subsidiaries, respectively, and as required.

     (j) Solvency. The Borrowers shall procure that each of them is, and shall
be, at all times Solvent.

     (k) Notice of Litigation. The Borrowers shall promptly give notice in
writing to the Administrative Agent of all litigation and of all proceedings
before any governmental or regulatory agency affecting itself which, if
adversely determined, would materially adversely affect the condition, financial
or otherwise, of the Borrowers.

     (l) Further Assurances. The Borrowers shall, from time to time upon the
request of the Administrative Agent on behalf of any Bank, accept for
cancellation any Note or Notes held by and payable to such Bank, and thereupon
the Borrowers shall execute and deliver to the Administrative Agent on behalf of
such Bank, payable to it and its registered assigns, a substitute Note or Notes,
prepared and delivered to the Borrowers by the Administrative Agent, in like
form and total aggregate amount as the canceled Note or Notes, but in any
denomination not smaller than One Million Dollars ($1,000,000) or such lesser
amount as such Bank may request as shall constitute the outstanding principal of
all outstanding Notes held by such Bank. The Borrowers shall do all things
necessary to grant to, and maintain in favor of, the Administrative Agent or the
Mortgagee on behalf of the Banks a valid, first priority security interest in
the Collateral, and to maintain each of the Loan Documents as legal, valid and
binding obligations, enforceable in accordance with their respective terms by
the Administrative Agent, the Mortgagee, the Banks, as the case may be. The
Borrowers shall take such other actions and deliver such instruments as may be
necessary or advisable, in the opinion of the Administrative Agent on behalf of
the Banks, to protect the security interest created in the Collateral, and the
rights and remedies of the Banks and the Mortgagee as the case may be, under the
Loan Documents.

     (m) Acquired Vessels. All vessels acquired by any of the Borrowers after
the Closing Date will be pledged or mortgaged to the Banks as Mortgaged Vessels

deliver to the Administrative Agent within five days of any Acquisition, two
original executed and acknowledged Mortgage Supplements (in the form of Exhibit
N hereto) in order to mortgage any Vessels acquired pursuant to the Acquisition.

     (n) Cash Management. The Borrowers shall maintain cash management systems
acceptable to the Administrative Agent, and the collection accounts for payment
of earnings of Mortgaged Vessels shall be subject to a first perfected priority
lien in favor of the Administrative Agent on behalf of the Banks.

     (o) Cash Collateral. In the event the face amount of the Letter of Credit
exceeds the amount to which the Letter of Credit should have been reduced as set
forth in Section 2.07(b), the Borrowers shall deposit additional funds in the
Cash Collateral Account equal to such excess amount.

     (p) Contracts. The Borrowers shall comply with the terms of all contracts
to which any of them is a party or by which any of them or any of their
properties may be bound, except that this Section 5.01(p) shall not apply to any
non-compliance that (a) has been excused or waived under the relevant contract
or (b) either alone or when aggregated with all other such non-compliances,
would not have a materially adverse effect on the Borrowers and their
consolidated Subsidiaries taken as a whole.

     (q) Corporate Structure. The Borrowers shall (i) maintain Hvide as a
publicly traded company as contemplated by the S-1; and (ii) ensure that the
Hvide stock is always entitled to be traded on public markets of the United
States and is not censored by any exchange, the SEC or comparable organization.

     SECTION 1.052 Negative Covenants. So long as any Advance or any other
Obligation shall remain unpaid or any Bank shall have any Commitment, the
Borrowers shall not, unless the Administrative Agent on behalf of the Banks
shall otherwise consent in writing in accordance with Section 7.04:

under one or more agreements or instruments relating to Indebtedness of such
Borrower or such Subsidiary, or any other event, shall occur and shall continue
after the applicable grace period, if any, specified in such agreement or
instrument, if the effect of such default or event is to accelerate, or to
permit the acceleration of, the maturity of such Indebtedness; or any such
Indebtedness shall be declared to be due and payable, or required to be prepaid
(other than by a regularly scheduled required prepayment), redeemed, purchased
or defeased, or an offer to prepay, redeem, purchase or defease shall be

                                  ARTICLE VII.

                          RELATION OF BANKS, ASSIGNMENT
                               AND PARTICIPATIONS

     SECTION 1.071 Banks and Administrative Agent. The general administration of
this Agreement and the Loan Documents shall be by the Administrative Agent, and
each Bank hereby authorizes and directs the Administrative Agent to take such
action (including without limitation retaining lawyers, accountants, surveyors
or other experts) or forbear from taking such action as in the Administrative
Agent's reasonable opinion may be necessary or desirable for the administration
hereof (subject to any direction of the Majority Banks and to the other

                                     -62-
<PAGE>   64
requirements of Section 7.04 hereof). The Administrative Agent shall inform each
Bank, and each Bank shall inform the Administrative Agent, of the occurrence of
any Event of Default promptly after obtaining knowledge thereof; however, unless
it has actual knowledge of an Event of Default, each of the Administrative
Agent, the Letter of Credit Agent and the Banks may assume that no Event of
Default has occurred.

     SECTION 1.072 Pro Rata Sharing. All commissions, fees, interest and
payments received by the Administrative Agent or any Bank under the terms of
this Agreement and the other Loan Documents and all expenses arising from the
administration hereof or the enforcement of any security and any sum realized
therefrom or from any setoff (other than sums applied to the payment of expenses
or for reimbursement of expenses paid) for which provision for allocation and
payment is not otherwise provided for herein or therein shall be divided pro
rata among the Banks in accordance with their Percentage Interests set forth in
Exhibit M hereto or, if applicable, in the Register. Notwithstanding the
foregoing, nothing herein shall be construed to prevent Citibank, N.A. or The
First National Bank of Boston from receiving solely for its own account as
neither Bank, Administrative Agent, Co-Agent nor Letter of Credit Agent
hereunder, such other fees and payments in respect of the Transaction as it may
mutually agree with the Borrowers. Each Bank shall pay to the Administrative
Agent promptly on demand any sums payable by such Bank hereunder. Under no
circumstances shall the Administrative Agent be obligated to expend its own
funds for the protection of the interests of the Banks, but the Administrative
Agent shall be entitled to be indemnified hereunder by the Banks in accordance
with their Percentage Interest prior to taking any action or expending any
funds.

     SECTION 1.073 Setoff. Any Bank which shall receive payment of or on account
of all or part of its claim against the Borrowers hereunder through the exercise
of any right of setoff, counterclaim, banker's lien, or secured claim under any
bankruptcy statute in a greater proportion than its Percentage Interest shall
promptly notify the Administrative Agent thereof as set forth in Section 8.05
hereof and shall be deemed to have purchased immediately prior to such payment a
ratable proportion of the claims of the other Banks so that all recoveries of
principal and interest shall be shared by the Banks in accordance with their
respective Percentage Interests. If all or any portion of such excess payment is
thereafter recovered from such Bank, such purchase shall be rescinded and the
purchase price restored of such recovery, but without interest.

     SECTION 1.074 Approvals. Upon any occasion requiring or permitting an
approval of any amendment or modification or any consent, waiver, declaring an
Event of Default or taking any action thereafter, or any other action on the
part of the Administrative Agent or the Banks under any of the Loan Documents,
(1) action may (but shall not be required to) be taken

                                      -63-


<PAGE>   65
by the Administrative Agent for and on the behalf or for the benefit of all
Banks, provided (A) that no contrary direction of the Majority Banks shall have
been previously received by the Administrative Agent, and (B) that the
Administrative Agent shall have received consent of the Majority Banks to enter
into any written amendment, waiver or modification of the provisions of any of
the Loan Documents, or to consent in writing to any material departure from the
terms of any Loan Documents by the Borrowers or any other party thereto or (2)
action shall be taken by the Administrative Agent upon the direction of the
Majority Banks, and any such action shall be binding on all Banks; provided
further, however, that unless all of the Banks agree in writing thereto, no
amendment, modification, waiver, consent or other action with respect to any of
the Loan Documents shall be effective which (a) increases the Commitment,
increases the Percentage Interest of any of the Banks or increases the Aggregate
Amount, (b) reduces any commission, fee, principal or interest owing to any Bank
hereunder or the method of calculation of any thereof, (c) extends Maturity
Date, the expiry date of any Letter of Credit or any other date on which any sum
is due hereunder, including, without limitation, the date or amount of any
prepayment required hereunder, (d) releases any Collateral, guaranty or other
security, (e) amends, waives or modifies the provisions of Section 5.01(e)
hereof, or (f) amends the provisions of this Section 7.04 or the definition of
Majority Banks.

     SECTION 1.075 Exculpation. The Administrative Agent shall not be liable or
answerable for anything whatsoever in connection with any of the Loan Documents
or other instrument or agreement required hereunder or thereunder, including
responsibility in respect of the execution, delivery, construction or
enforcement of any of the Loan Documents or any such other instrument or
agreement, or for any action taken or not taken by the Administrative Agent in
any case involving exercise of any power or authority conferred upon the
Administrative Agent under any thereof, except for its wilful misconduct or
gross negligence, and the Administrative Agent shall have no duties or
obligations other than as provided herein and therein. The Administrative Agent
shall be entitled to rely on any opinion of counsel (including counsel for any
of the Borrowers or any of their Subsidiaries) in relation to any of the Loan
Documents or any other instrument or agreement required hereunder or thereunder
and upon writings, statements and communications received from the Borrowers or
any of its Subsidiaries (including any representation made in or in connection
with any Loan Document), or from any other party to any of the Loan Documents or
any documents referred to therein or any other Person, firm or corporation
reasonably believed by it to be authentic, and the Administrative Agent shall
not be required to investigate the truth or accuracy of any writing or
representation, nor shall the Administrative Agent be liable for any action it
has taken or omitted in good faith on such reliance.

<PAGE>   66
     SECTION 1.076 Indemnification. Each Bank agrees to indemnify the
Administrative Agent, except to the extent reimbursed by the Borrowers and
except in the case of any suit by any Bank against the Administrative Agent
resulting in a final judgment against the Administrative Agent, ratably
according to its Percentage Interest against all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursement of any kind or nature whatsoever (except to the extent the
foregoing result from the Administrative Agent's gross negligence or wilful
misconduct) which may be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of (y) any of the
Loan Documents or any other instrument or agreement contemplated hereunder or
thereunder or (z) any action taken or omitted by the Administrative Agent under
any of the Loan Documents or such other instrument or agreement.

     SECTION 1.077 Administrative Agent, Co-Agents and Letter of Credit Agent as
Bank. Each of the Administrative Agent, the Co-Agents and the Letter of Credit
Agent shall, in its individual capacity, have the same rights and powers
hereunder as any other Bank and may exercise the same as though it were not an
agent; the term "Banks" shall include each of the Administrative Agent, the
Co-Agents and the Letter of Credit Agent in its individual capacity to the
extent of its Percentage Interest. Each of the Administrative Agent, the
Co-Agents and the Letter of Credit Agent and its respective Subsidiaries and
Affiliates may accept deposits from, lend money to, and generally engage in any
kind of banking, trust or other business with each of the Borrowers, and their
respective Subsidiaries and Affiliates, as if it were not the Administrative
Agent, Co-Agents or Letter of Credit Agent, as the case may be.

     SECTION 1.078 Notice of Transfer; Resignation; Successor Administrative
Agent. (a) The Administrative Agent may deem and treat a Bank party to this
Agreement as the owner of such Bank's interest in any Loan and any other
instrument or agreement of the assignment or transfer thereof, executed by such
Bank and otherwise in compliance with the requirements of Section 7.10 hereof,
shall have been received and accepted by the Administrative Agent. The
Administrative Agent shall resign if directed by the Majority Banks. The
Administrative Agent may resign at any time by notice to the Borrowers and the
Banks.

     (b) Any successor Administrative Agent shall be appointed by the Majority
Banks and shall be a bank or trust company reasonably satisfactory to the
Majority Banks, and, so long as no Event of Default shall have occurred and be
continuing, appointment of any such successor Administrative Agent (whether by
the Majority Banks or by the retiring Administrative Agent) shall be subject to
the consent of the Borrowers, such consent not to be unreasonably denied or
withheld. If no successor Administrative Agent shall have been so appointed by
the Majority Banks, and shall have accepted such

                                      -65-


<PAGE>   67
appointment, within 30 days after the retiring Administrative Agent's giving of
notice of resignation or the Majority Bank's removal of the Administrative
Agent, then such retiring Administrative Agent may, on behalf of the Banks,
appoint a successor Administrative Agent, which shall be a commercial bank
organized under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $50,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations under this Agreement. After
any retiring Administrative Agent's resignation or removal hereunder as
Administrative Agent, the provisions of this Article VII shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.

     SECTION 1.079 Credit Decision; Not Trustee. Each Bank represents that it
has made, and agrees that it shall continue to make its own independent
investigation of the financial condition of each of the Borrowers and their
Subsidiaries and its own appraisal of the creditworthiness of each of the
Borrowers and their Subsidiaries in connection with the making and performance
of the Loan Documents. The Administrative Agent has and shall have no duty or
responsibility whatsoever on the date hereof or, except as otherwise expressly
provided in this Agreement at any time hereafter, to provide any Bank with any
credit or other information. Nothing herein shall (nor shall it be construed so
as to) constitute the Administrative Agent or the Letter of Credit Agent a
trustee for each of the Borrowers or their Subsidiaries or impose on it any
duties or obligations other than those for which express provision is made in
this Agreement or under the other Loan Documents.

     SECTION 7.10 Assignments and Participation; Termination. (a) Each Bank may
assign to one or more banks or other entities all or a portion of its rights and
obligations under this Agreement (including, without limitation, all or a
portion of its Commitment, the Advances owing to it and the Note or Notes held
by it); provided, however, that (i) each such assignment shall be of a constant,
and not a varying, percentage of all rights and obligations under this
Agreement, (ii) unless the Borrowers shall otherwise agree with the assigning
Bank, the amount of the Commitment of the assigning Bank being assigned pursuant
to each such assignment (determined as of the date of the Assignment and
Acceptance with respect to such assignment) shall in no event be less than Five
Million Dollars ($5,000,000) or such lesser amount as shall constitute all of
such assigning Bank's Commitment and the outstanding principal of Notes payable
to it, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the
parties to each such assignment shall

                                      -66-


<PAGE>   68
execute and deliver to the Administrative Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, together with any Note
or Notes subject to such assignment and a processing recordation fee of $3,000;
provided further, however, that so long as no Event of Default shall have
occurred and be continuing, each such assignment shall be subject to the consent
of the Borrowers, which consent shall not unreasonably be denied and which
consent shall be deemed given unless the Borrowers gives the assigning Bank and
the Administrative Agent written notice of and a reasonable basis for its denial
not later than ten (10) Business Days following telex, telefacsimile or cable
notice given to the Borrowers by the assigning Bank or the Administrative Agent
of the name of the proposed transferee, the amount of Commitment to be assigned
and such information as the Borrowers may reasonably request for purposes of
making an informed judgment. Prior to contacting a prospective assignee in
connection with a proposed assignment hereunder, the assignor Bank shall give
the Borrowers notice of the identity of any such prospective assignee. Any
consent to assignment untimely or unreasonably denied by the Borrowers shall be
void and of no effect, and shall not preclude or bar any assignment otherwise
permitted by this Section 7.10(a). Any assignment or purported assignment not in
compliance with this Section shall be void and of no effect. Without regard to
any of the other terms of this Agreement or of any other agreement, any Bank may
assign, as collateral or otherwise, any of its rights (including, without
limitation, rights to payments of principal and/or interest on the Notes) under
this Agreement to any Federal Reserve Bank of the United States without notice
to or consent of the Borrowers, the Agent or any other Person.

     (b) Upon such execution, delivery, acceptance and recording, from and after
the effective date specified in each Assignment and Acceptance (x) the assignee
thereunder shall be a party hereto and, to the extent that rights and
obligations hereunder have been assigned to it pursuant to such Assignment and
Acceptance and subject to the foregoing, have the rights and obligations of a
Bank hereunder and (y) the Bank assignor thereunder shall, to the extent that
rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Bank's rights
and obligations under this Agreement, such Bank shall cease to be party hereto).

     (c) By executing and delivering an Assignment and Acceptance, the Bank
assignor thereunder and the assignee thereunder confirm to and agree with each
other and the other parties hereto as follows: (i) other than as provided in
such Assignment and Acceptance, such assigning Bank makes no representation or
warranty and assumes no responsibility with respect to any statements,
warranties or representations made in connection with this Agreement or the
execution, legality,

                                      -67-



<PAGE>   69
validity, enforceability, genuineness, sufficiency or value of this Agreement or
any other instrument or document furnished pursuant hereto; (ii) such assigning
Bank makes no representation or warranty and assumes no responsibility with
respect to the financial condition of any of the Borrowers or its Subsidiaries
or the performance or observance by any of the Borrowers or its Subsidiaries of
any of its obligations under this Agreement or any other instrument or document
furnished pursuant hereto; (iii) such assignee confirms that it has received a
copy of this agreement, together with copies of the Borrowers' financial
statements referred to herein, and such other documents and information as it
has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance; (iv) such assignee will, independently and
without reliance upon the Administrative Agent, such assigning Bank or any other
Bank, and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such assignee confirms that it is an Eligible
Assignee; (vi) such assignee appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers as are reasonably incidental thereto; and (vii) such
assignee agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Bank.

     (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Bank and an assignee representing that it is an Eligible Assignee, the
Administrative Agent shall, if such Assignment and Acceptance has been completed
and is in substantially the form of Exhibit I hereto, (i) accept such Assignment
and Acceptance, (ii) record the information contained therein in the Register
(including the transfer of Notes to such Eligible Assignee by the assigning
Bank) and (iii) give prompt notice and an execution counterpart thereof to the
Borrowers. Within five (5) Business Days after its receipt of such notice, the
Borrowers, at the expense of the assigning Bank, shall execute and deliver to
the Administrative Agent in exchange for the surrendered Note or Notes a new
Note or new Notes, as the case may be, of the same series to the order of such
Eligible Assignee in an amount equal to the Commitment assumed by it pursuant to
such Assignment and Acceptance. Such new Note or Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Note or Notes, shall be dated the effective date of such Assignment and
Acceptance and shall otherwise be in substantially the form of Exhibit I hereto.

     (e) The Administrative Agent shall maintain at its address referred to in
Section 8.02 of this Agreement a register for the recordation of the names and
addresses of the Banks and the Commitment of, and principal amount of the
Advance owing and

                                      -68-


<PAGE>   70
each Note payable to, each Bank from time to time and a copy of each Assignment
and Acceptance delivered to and accepted by it (the "Register"). The entries in
the Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrowers, the Administrative Agent, the Letter of Credit Agent
and the Banks may treat each Person whose name is recorded in the Register as a
Bank hereunder for all purposes of this Agreement. The Register shall be
available for inspection by the Borrowers or any Bank at any reasonable time and
from time to time upon reasonable prior notice and each shall be entitled to
make copies thereof at its expense.

     (f) Each Bank may grant participations to one or more banks or other
entities in or to all or any part of its rights and obligations under this
Agreement (including, without limitation, all or a portion of its Commitment and
the Advance owing to it); provided, however, that, notwithstanding the grant of
any such participation by any Bank, such participation, and the right to grant
such a participation, shall be expressly subject to the following conditions and
limitations: (i) such Bank's obligations under this Agreement (including without
limitation, its Commitment to the Borrowers hereunder) shall remain unchanged,
(ii) such Bank shall remain solely responsible to the other parties hereto for
the performance of such obligations, (iii) such Bank shall remain the holder of
any such Note and Advance for all purposes of this Agreement, (iv) the
Borrowers, the Administrative Agent and the other Banks shall continue to deal
solely and directly with such Bank in connection with such Bank's rights and
obligations under the Agreement, (v) such Bank shall continue to be able to
agree to any modification or amendment of this Agreement or any waiver hereunder
without the consent, approval or vote of any such participant or group of
participants, other than modifications, amendments, and waivers which (a)
postpone the Maturity Date or any date fixed for any payment of, or reduce any
payment of, principal of or interest on such Bank's Advance or any fees or other
amounts payable under this Agreement, or (b) increase the amount of such Bank's
Commitment, or (c) change the interest rate payable under this Agreement, or (d)
release all or any substantial part of the Collateral, provided that if a Bank
agrees to any modification or waiver relating to items (a) through (d), the
Borrowers, the Administrative Agent and each other Bank may conclusively assume
that such Bank duly received any necessary consent of each of its participants,
and (vi) except as contemplated by the immediately preceding clause (v), no
participant shall be deemed to be or to have any of the rights or obligations of
a "Bank" hereunder.

     (g) Any Bank may, in connection with any assignment, designation or
participation or proposed assignment, designation or participation pursuant to
this Section 7.10, disclose to the assignee or participant, or proposed
assignee, or participant, any information relating to any of the Borrowers or
their Subsidiaries that is otherwise publicly available and has been furnished
to such Bank by or on behalf of the Borrowers, provided

                                      -69-


<PAGE>   71
that without the Borrowers' prior written or oral consent, no Bank shall
disclose to any proposed assignee or proposed participant, any such information
not otherwise publicly available relating to the Borrowers or its Subsidiaries
as has been furnished to such Bank by or on behalf of the Borrowers hereby;
provided, however, any Bank may disclose such information to a potential
assignee if prior to any disclosure, the potential assignee has signed a
confidentiality agreement in form and substance reasonably satisfactory to
Borrowers. Any Bank that sells or grants a participation pursuant to this
Section 7.10 shall (i) in a timely manner withhold or deduct from each payment
to the holder of such participation the amount of any Taxes required under
Applicable Law to be withheld or deducted from such payment that have not been
withheld or deducted by the Borrowers or the Administrative Agent or the Letter
of Credit Agent (ii) pay such Taxes in a timely manner to the appropriate
authorities and (iii) indemnify the Borrowers and the Administrative Agent or
the Letter of Credit Agent for any Taxes, losses, costs or expenses that they
may incur as a result of any failure to pay such Taxes to the appropriate
authority when due.

     SECTION 7.11 Co-Agents. Each of the Co-Agents shall have no duties,
responsibilities, rights or liabilities as Co- Agent, as the case may be, under
this Agreement or any of the other Loan Documents and shall not be liable or
answerable for anything whatsoever in connection with any of the Loan Documents
or other instrument or agreement required hereunder or thereunder, including
responsibility in respect of the execution, delivery, construction or
enforcement of any of the Loan Documents or any such other instrument or
agreement, or for any action taken or not taken by any Person with respect
thereto. Each of the Co-Agents has and shall have no duty or responsibility
whatsoever on the date hereof or at any time hereafter, to provide any Bank with
any credit or other information. Nothing herein shall (nor shall it be construed
so as to) constitute the Co-Agents a trustee for the Borrowers or their
Subsidiaries or impose on it any duties or obligations whatsoever under this
Agreement, the other Loan Documents, or otherwise.


                                  ARTICLE VIII.

                                  MISCELLANEOUS

     SECTION 1.081 Amendments. No amendment, restatement, supplement or
modification to this Agreement shall be enforceable against the Borrowers unless
the same shall be in writing and signed by the Borrowers. No amendment or waiver
of any provision of this Agreement or any instrument delivered hereunder, nor
consent to any departure by the Borrowers therefrom, shall in any event be
effective unless the same shall be in writing and signed by the Administrative
Agent and, to the extent required by Section 7.04 hereof, the Majority Banks or
each Bank, as the case

                                      -70-


<PAGE>   72
may be, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given, provided that in the
absence of actual notice to the contrary, the Borrowers may conclusively rely on
all writings purported to be delivered and actions taken by the Administrative
Agent on behalf of the Banks or the Majority Banks, as the case may be, without
inquiry as to the authority of the Administrative Agent with respect thereto.

     SECTION 1.082 Notices. All notices, demands and other communications
provided for hereunder shall be in writing (including telegraphic communication)
telexed, telecopied or telegraphed or delivered, if to the Borrowers, at its
address set forth below its signature herein written; if to the Administrative
Agent, at its address set forth below its signature herein written; and if to a
Bank other than the Administrative Agent, the Letter of Credit Agent at its
address set forth below its signature herein written; or, as to each party, at
such other address as shall be designated by such party in a notice to the other
parties hereto. All such notices and communications shall, when telexed,
telecopied, or telegraphed, be effective upon the earliest of (i) actual receipt

addressee's address) transmitted by telecopy or telex or delivered to the
telegraph company, respectively, except that notices and communications to the
Administrative Agent pursuant to Article II hereof shall not be effective until
received by the Administrative Agent.

     SECTION 1.083 No Waiver; Remedies. Regardless of any fact known or
investigation undertaken by the Administrative Agent or any Bank, no failure on
the part of the Administrative Agent or any Bank to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.

     SECTION 1.084 Costs, Expenses, Fees and Indemnities; Concerning the
Mortgagee and the Trustee. (a) Each Borrower agrees to pay on demand (i) in
connection with the preparation, execution, and delivery of this Agreement and
the instruments and other documents to be delivered hereunder, (x) the
reasonable fees and out-of-pocket expenses of Messrs. Winthrop, Stimson, Putnam

Agent and the Banks and Messrs. Bingham, Dana & Gould as special counsel to the
Letter of Credit Agent (and any local counsel retained by such firm) with
respect to the closing of the Transaction and (y) all other reasonable and
customary third party costs and expenses of the Banks and the Administrative
Agent (other than any other legal fees and related expenses incurred by them)
and (z) the reasonable fees and out- of-pocket expenses of the Mortgagee and the
Trustee (including

                                      -71-


<PAGE>   73
reasonable attorney fees and out-of-pocket expenses) and (ii) after the Closing
Date, all reasonable and customary third party costs and expenses in connection
with the administration of this Agreement and the other instruments and
documents to be delivered hereunder, including, without limitation, (y) the
reasonable fees and out-of-pocket expenses of any counsel for the Administrative
Agent or the Banks in connection with advice given the Administrative Agent or
the Banks, from time to time, as to their rights and responsibilities under this
Agreement and in connection with the waiver, supplementation or amendment of
such instruments and documents and (z) the reasonable fees and out-of- pocket
expenses of the Mortgagee (including the reasonable fees and out-of-pocket
expenses of counsel to the Mortgagee) and the indemnities payable to the
Mortgagee as trustee under the Master Vessel and Collateral Trust Agreement,
respectively, pursuant to the terms hereof. The Borrowers further agree to pay
on demand all losses, costs and expenses, if any (including, without limitation,
counsel fees and expenses), in connection with the enforcement of this Agreement
and the instruments and other documents delivered hereunder, including, without
limitation, losses, costs and expenses sustained as a result of a Default by any
of the Borrowers in the performance of its obligations contained in this
Agreement or any instrument or document delivered hereunder.

     (b) If, for any reason, including maturity or demand of the Loan under
Article VI, or prepayment of the Loan, in whole or in part, the Administrative
Agent or any of the Banks receives payment of principal of or interest on an
Advance on any day other than the Principal Payment Date or Interest Payment
Date for such Advance, the Borrowers shall pay to the Administrative Agent on
behalf of the Banks on demand any amounts required to compensate the Banks for
any breakage costs (including cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds in respect of such
payment) and any additional losses, costs or expenses which any Bank may incur
as a result of such payment, prepayment, purchase or acceleration in connection
with unwinding or liquidating of any deposits or funding or financing
arrangement with its funding sources (collectively, "Breakage Costs"), provided
that the Bank shall have delivered to the Administrative Agent and the Borrowers
a certificate as to the amount of such Breakage Costs, which certificate shall
be binding, absent manifest error, except that the failure of the Bank to
provide such certificate shall in no way relieve the Borrowers of their
obligations under this Section 8.04(b).

     (c) Each Borrower agrees to indemnify and hold harmless each of the Banks
and the Administrative Agent, the Letter of Credit Agent and its and their
respective Affiliates, directors, officers, employees, agents, representatives,
counsel and advisors (each an "Indemnified Party") from and against any and all
claims, damages, losses, liabilities and expenses (including, without
limitation, reasonable fees and disbursements

                                      -72-


<PAGE>   74
of counsel and the costs of investigation and defense thereof) which may be
incurred by or asserted or awarded against any Indemnified Party, in each case
based upon, arising out of or in connection with or by reason of, the
Transaction (including, without limitation, any act or failure to act by the
Administrative Agent, the Letter of Credit Agent or the Mortgagee where such act
or failure to act was taken pursuant to the Borrowers' request, any Transaction
contemplated by this Agreement, or any Loan Document), whether or not any
Advance hereunder is made, except to the extent that such claim, damage, loss,
liability or expense results from the gross negligence or willful misconduct of
such Indemnified Party. The indemnities of this Loan Agreement shall survive the
termination of this Loan Agreement and the other Loan Documents.

     SECTION 1.085 Right of Setoff. Upon the occurrence and during the
continuance of an Event of Default, each of the Administrative Agent, the Letter
of Credit Agent, each Bank and their respective Affiliates is hereby authorized
at any time and from time to time, to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) any time held, and other Indebtedness at any time owing,
by the Administrative Agent, the Letter of Credit Agent, a Bank or their
respective Affiliates to or for the credit or the account of the Borrowers
against any and all of the obligations of the Borrowers now or hereafter
existing under the Agreement and any instrument delivered hereunder,
irrespective of whether or not the Bank shall have made any demand under this
Agreement or such instrument and although such obligations may be unmatured. The
Administrative Agent, the Letter of Credit Agent and each Bank agrees promptly
to notify the Borrowers, as the case may be, and the Administrative Agent, the
Letter of Credit Agent, as the case may be, after any such setoff and
application, provided that the failure to give such notice shall not affect the
validity of such setoff and application. The rights of the Administrative Agent,
the Letter of Credit Agent, each Bank and their respective Affiliates under this
Section are in addition to other rights and remedies (including, without
limitation, other rights of setoff) which the Administrative Agent, the Letter
of Credit Agent or such Bank may have.

     SECTION 1.086 Joint and Several Liability of Borrowers. Each Borrower
agrees with the Banks, the Letter of Credit Agent and the Administrative Agent
that such Borrower shall be jointly and severally liable for the Obligations
with the other Borrowers except that Seabulk Transmarine Partnership, Ltd.'s
liability hereunder shall be limited to such amounts as may be recovered
pursuant to the Mortgage and Assignments in respect of M/V SEABULK AMERICA.

     SECTION 1.087 Judgment. (a) If for the purposes of obtaining judgment in
any court it is necessary to convert a sum due hereunder or under any instrument
delivered hereunder in

                                      -73-

<PAGE>   75
United States Dollars into another currency, the parties hereto agree, to the
fullest extent permitted by law, that the rate of exchange used shall be that at
which in accordance with normal banking procedures the Administrative Agent, the
Letter of Credit Agent or the Banks, as the case may be, could purchase United
States Dollars with such other currency on the Business Day preceding that on
which final judgment is given.

     (b) The obligation of a Borrower in respect of any sum due from it to the
Administrative Agent, the Letter of Credit Agent or any Bank hereunder or under
such instrument shall, notwithstanding any judgment in a currency other than
United States Dollars, be discharged only to the extent that on the Business Day
following receipt by the Administrative Agent, the Letter of Credit Agent or
such Bank of any sum adjudged to be so due in such other currency the
Administrative Agent, the Letter of Credit Agent or such Bank, as the case may
be, may in accordance with normal banking procedures purchase United States
Dollars with such other currency; if the United States Dollars so purchased are
less than the sum originally due to the Administrative Agent, the Letter of
Credit Agent or such Bank, as the case may be, in United States Dollars, each
Borrower agrees, as a separate obligation and notwithstanding any such judgment,
to indemnify the Administrative Agent, the Letter of Credit Agent or such Bank,
as the case may be, against such loss, and if the United States Dollars so
purchased exceed the sum originally due to the Administrative Agent, the Letter
of Credit Agent or such Bank in United States Dollars, the Administrative Agent,
the Letter of Credit Agent or such Bank shall remit such excess to such
Borrower.

     SECTION 1.088 Consent to Jurisdiction; Waiver of Immunities. (a) Each
Borrower hereby irrevocably submits to the jurisdiction of any New York State
court sitting in New York County and to the jurisdiction of the United States
District Court for the Southern District of New York in any action or proceeding
arising out of or relating to this Agreement or the Notes or the other Loan
Documents, and each Borrower hereby irrevocably agrees that all claims in
respect of such action or proceeding may be heard and determined in such New
York State or Federal court. Each Borrower irrevocably waives, to the fullest
extent it may effectively do so, the defense of an inconvenient forum to the
maintenance of such action or proceeding or the failure to join any other
Borrower as a necessary party to such action. The Borrowers hereby irrevocably
appoint CT Corporation (the "Process Agent"), with an office on the date hereof
at 1633 Broadway, New York, New York, 10019, United States, as their agent to
receive on behalf of each of them and their property service of copies of the
summons and complaint and any other process which may be served in any such
action or proceeding. Such service may be made by mailing or delivering a copy
of such process to the Borrowers in care of the Process Agent (or any successor
thereto, as the case may be) at such Process Agent's above address (or the
address of any successor thereto, as the

                                      -74-


<PAGE>   76
case may be), and the Borrowers hereby irrevocably authorize and direct the
Process Agent (and any successor thereto) to accept such service on their
behalf. The Borrowers shall appoint a successor agent for service of process
should the agency of CT Corporation terminate for any reason, and further shall
at all times maintain an agent for service of process in New York, New York, so
long as there shall be outstanding any Obligations under the Loan Documents. The
Borrowers shall give notice to the Administrative Agent of any appointment of
successor agents for service of process, and shall obtain for each successor
agent a letter of acceptance of appointment and promptly deliver the same to the
Administrative Agent. As an alternative method of service, each Borrower also
irrevocably consents to the service of any and all process in any such action or
proceeding by the mailing of copies of such process to it at its address
specified in Section 8.02 hereof. Without waiver of its rights of appeal
permitted by relevant law, each Borrower agrees that a final judgment in any
such action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the judgment or in any other manner provided by law.

     (b) Nothing in this Section 8.07 shall affect the right of the
Administrative Agent, the Letter of Credit Agent or any Bank to serve legal
process in any other manner permitted by law, or affect the right of the
Administrative Agent, the Letter of Credit Agent or any Bank to bring any action
or proceeding against any Borrower or its respective properties in the courts of
any other jurisdiction.

     (c) To the extent that any Borrower has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process (whether
through service or notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with respect to itself or its property, such
Borrower hereby irrevocably waives such immunity in respect of its obligations
under this Agreement and the Notes and each of the other Loan Documents.

     SECTION 1.089 Binding Effect; Merger; Severability; GOVERNING LAW. (a) This
Agreement shall be binding upon, and shall inure to the benefit of, the
Borrowers, the Administrative Agent, the Letter of Credit Agent and each Bank,
and their respective successors and assigns, except that the Borrowers shall not
have the right to assign its rights hereunder or any interest herein. Each Bank
may, to the extent permitted under this Agreement, assign to any other financial
institution all or any part of, or any interest in, the Bank's rights and
benefits hereunder and under any instrument delivered hereunder, and to the
extent of such assignment such assignee shall have the same rights and benefits
against the Borrowers as it would have had if it were the Bank hereunder.

     (b) The Loan Documents, together with all attachments and exhibits to each
of them and all other documents referenced

                                      -75-



<PAGE>   77
herein and therein, and delivered hereunder and thereunder and pursuant hereto
and thereto, constitute the entire agreement among the parties with respect to
the subject matter hereof and thereof, and supersede all prior and
contemporaneous written and oral understandings and agreements related thereto
among the parties.

     (c) If any work, phrase, sentence, paragraph, provision or section of the
Loan Documents shall be held, declared, pronounced or rendered invalid, void,
unenforceable or inoperative for any reason by any court of competent
jurisdiction, governmental authority, statute, or otherwise, such holding,
declaration, pronouncement or rendering shall not adversely affect any other
word, phrase, sentence, paragraph, provision or section of the Loan Documents,
which shall otherwise remain in full force and effect and be enforced in
accordance with their respective terms.

     (d) This Agreement has been delivered in New York, New York. THIS AGREEMENT
AND THE NOTES SHALL BE GOVERNED BY, AND BE CONSTRUED IN ACCORDANCE WITH, THE
INTERNAL LAWS OF THE STATE OF NEW YORK.

     SECTION 8.10 Counterparts. This Agreement may be executed in as many
counterparts as may be deemed necessary or convenient and by each party hereto
on separate counterparts, each of which, when so executed, shall be deemed as
original, but all such counterparts shall constitute but one and the same
agreement.

     SECTION 8.11 WAIVER OF JURY TRIAL. BY ITS SIGNATURE BELOW WRITTEN EACH
PARTY HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY
ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT,
THE LOAN DOCUMENTS HEREIN DESCRIBED OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY.

     SECTION 8.12 Effectiveness. This Agreement shall not come into effect until
the Effective Date. Prior to the Effective Date, the Credit Agreement dated as
of September 28, 1994, as amended by Amendment No. 1 dated as of May 15, 1995
and Amendment No. 2 dated as of March 26, 1996 and as subsequently amended and
restated by an Amended and Restated Credit Agreement dated as of June 21, 1996
which was amended by Amendment No. 1 dated as of December 17, 1996, shall be
binding upon the parties hereto.
