PROSPECTUS            SUBJECT TO COMPLETION, DATED OCTOBER 15, 1997
    
           , 1997

                            2,300,000 Preferred Securities
                                  Hvide Capital Trust

                  (Liquidation Preference $50 per Preferred Security)
                                          and
   
                                   4,176,880 Shares
    
                               Hvide Marine Incorporated
                                 Class A Common Stock
   
     (Including 4,035,120 Shares Issuable Upon Conversion of the Preferred 
                                     Securities)
    
   
         This Prospectus  relates to the resale by the holders thereof of 6 1/2%
Trust  Convertible  Preferred  Securities  (the "Preferred  Securities"),  which
represent undivided beneficial interests in the assets of Hvide Capital Trust, a
statutory  business  trust  created under the laws of the State of Delaware (the
"Issuer"  or the  "Trust"),  and the shares of Class A Common  Stock,  par value
$0.001 per share (the "Hvide Class A Common  Stock" or "Class A Common  Stock"),
of Hvide Marine Incorporated,  a Florida corporation ("Hvide" or the "Company"),
issuable upon conversion of the Preferred  Securities.  The Preferred Securities
were issued and sold by the Issuer on June 27, 1997 (the "Original Offering") to
Donaldson,  Lufkin & Jenrette Securities  Corporation,  Howard, Weil, Labouisse,
Friedrichs  Incorporated,  and Raymond  James &  Associates,  Inc. (the "Initial
Purchasers")  and  were  simultaneously  resold  by the  Initial  Purchasers  in
transactions exempt from the Securities Act of 1933, as amended (the "Securities
Act"). The Preferred  Securities are traded in the Private Offering,  Resale and
Trading through  Automated  Linkages  ("PORTAL")  Market.  All of the beneficial
interests in the assets of the Issuer  represented  by common  securities of the
Issuer (the "Common  Securities")  are owned by Hvide. The Issuer exists for the
sole  purpose of issuing the  Preferred  Securities  and Common  Securities  and
investing the proceeds therefrom in 6 1/2% Convertible  Subordinated  Debentures
due June 15, 2012 (the "Debentures")  issued by Hvide. The Preferred  Securities
have a preference under certain circumstances with respect to cash distributions
and amounts  payable on  liquidation,  redemption  or otherwise  over the Common
Securities.  See  "Description  of the  Preferred  Securities--Subordination  of
Common  Securities."  This  Prospectus  also relates to the resale by the holder
thereof  of  141,760  shares of Class A Common  Stock  issued by the  Company in
connection with an acquisition of certain vessels.
    
   
         The  Preferred  Securities,  the  Class A Common  Stock  issuable  upon
conversion of the Preferred  Securities,  and the Class A Common Stock issued in
connection with an acquisition  (collectively  the "Offered  Securities") may be
offered  and sold  from  time to time by the  holders  named  herein or by their
transferees,  pledgees, donees or their successors  (collectively,  the "Selling
Holders") pursuant to this Prospectus. The Offered Securities may be sold by the
Selling  Holders from time to time  directly to  purchasers  or through  agents,
underwriters or dealers.  See "Selling  Holders" and "Plan of  Distribution." If
required,  the names of any such agents or underwriters  involved in the sale of
the Offered Securities and the applicable agent's commission,  dealer's purchase
price or  underwriter's  discount,  if any, will be set forth in an accompanying
supplement to this Prospectus (the "Prospectus Supplement"). The Selling Holders
will receive all of the net proceeds from the sale of the Offered Securities and
will pay all underwriting discounts,  selling commissions and transfer taxes, if
any,  applicable  to any such  sale.  Hvide is  responsible  for  payment of all
expenses  incident to the  registration of the Offered  Securities.  The Selling
Holders and any  broker-dealers,  agents or underwriters that participate in the
distribution of the Offered Securities may be deemed to be "underwriters" within
the meaning of the Securities  Act, and any commission  received by them and any
profit on the resale of the Offered  Securities  purchased by them may be deemed
to be underwriting  commissions or discounts under the Securities Act. See "Plan
of Distribution" for a description of indemnification arrangements.
    
         Holders  of  the   Preferred   Securities   are   entitled  to  receive
preferential  cumulative cash distributions from the Issuer at an annual rate of
6 1/2% of the liquidation preference of $50 per Preferred Security accruing from
June 27, 1997 and payable quarterly in arrears on January 1, April 1, July 1 and
October  1 of each  year,  commencing  October  1, 1997  ("Distributions").  The
distribution rate and the distribution and other payment dates for the Preferred
Securities  correspond to the interest rate and interest and other payment dates
in the  Debentures,  which are the sole  assets of the Issuer.  As a result,  if
principal or interest is not paid on the Debentures,  no amounts will be paid on
the Preferred Securities.
   
         Each Preferred  Security is convertible in the manner  described herein
at the option of the holder, at any time beginning  September 25, 1997 and prior
to the  Conversion  Expiration  Date (as defined  herein),  into shares of Hvide
Class A Common Stock at the rate of 1.7544  shares of Hvide Class A Common Stock
for each  Preferred  Security  (equivalent  to a conversion  price of $28.50 per
share  of  Hvide  Class A  Common  Stock),  subject  to  adjustment  in  certain
circumstances.  See "Description of the Preferred Securities--Conversion Rights"
and  "Description of Hvide Capital Stock." The last reported sale price of Hvide
Class A Common  Stock,  which is traded  under the  symbol  "HMAR" on The Nasdaq
National Market,  on October 14, 1997 was $ 35.25 per share.  (continued on next
page)
    

   
See "Risk Factors"  beginning on page 13 for a discussion of certain  factors to
be considered in connection  with an investment in the Preferred  Securities and
the Class A Common Stock.
    

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE  COMMISSION OR ANY STATE  SECURITIES  COMMISSION NOR HAS THE SECURITIES
AND  EXCHANGE  COMMISSION  OR ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

(continued from cover page)

         In order to maintain the eligibility of Hvide to operate vessels in the
U.S.  domestic trade,  75% of the outstanding  capital stock and voting power of
Hvide is required to be held by U.S. citizens.  As a result of this requirement,
any non-citizen  holder of the Preferred  Securities or the Debentures  will, to
the extent the  conversion  thereof  into shares of Hvide  Class A Common  Stock
would  cause  more than 25% of  Hvide's  outstanding  Common  Stock (as  defined
herein)  to be  held  by  non-citizens,  be  unable  to  convert  its  Preferred
Securities or  Debentures  into shares of Hvide Class A Common Stock and will be
required to sell its Preferred  Securities  or  Debentures  to U.S.  citizens in
order to  realize  the  economic  benefits,  if any,  of  conversion.  See "Risk
Factors--Restriction on Foreign Ownership of Common Stock; Possible Inability to
Convert Preferred Securities and Debentures."

         So long as Hvide is not in default in the  payment of  interest  on the
Debentures  and no other event of default under the  Debentures  is  continuing,
Hvide has the right to defer  payment of interest on the  Debentures at any time
or from time to time for a period not  exceeding 20  consecutive  quarters  with
respect to each deferral period (each, an "Extension Period"),  provided that no
Extension  Period may extend beyond the stated maturity of the Debentures.  Upon
the termination of any such Extension Period and the payment of all amounts then
due on any Interest Payment Date (as defined herein), Hvide may elect to begin a
new Extension Period subject to the  requirements set forth herein.  If interest
payments on the  Debentures  are so  deferred,  Distributions  on the  Preferred
Securities  will also be deferred  and Hvide will not be  permitted,  subject to
certain  exceptions set forth herein, to declare or pay cash  distributions with
respect to Hvide's capital stock or debt securities that rank pari passu with or
junior to the Debentures.

         During an Extension Period, interest on the Debentures will continue to
accrue  (and the  amount of  Distributions  to which  holders  of the  Preferred
Securities are entitled will accumulate at the stated rate per annum, compounded
quarterly)  and  holders of  Preferred  Securities  will be  required  to accrue
interest income for United States federal income tax purposes.  See "Description
of the  Debentures--Option  to Extend  Interest  Payment  Period"  and  "Certain
Federal Income Tax Consequences--Original Issue
Discount."

         Except as provided below, the Preferred  Securities may not be redeemed
by the Issuer prior to July 2, 2000.  The  Preferred  Securities  are subject to
mandatory redemption,  in whole or in part, on or after such date, at redemption
prices set forth herein,  upon any permitted  redemption of Debentures by Hvide.
See "Description of the Preferred Securities--Optional Redemption." In addition,
the Preferred  Securities are subject to mandatory redemption upon the repayment
at maturity or as a result of acceleration of the Debentures.  See  "Description
of the Preferred Securities--Mandatory Redemption."

         Under certain circumstances following the occurrence of a Special Event
(as defined herein),  the Preferred Securities are also subject to (i) exchange,
at the option of the Issuer in the manner described herein,  for Debentures (see
"Description of the Preferred Securities--Special Event Exchange or Redemption")
and (ii)  redemption,  in whole or in part,  on or after July 2,  2000,  if such
Special Event  constitutes a Tax Event (as defined  herein).  At any time, Hvide
will have the right to  terminate  the  Issuer  and cause the  Debentures  to be
distributed  to the holders of the Preferred  Securities in  liquidation  of the
Issuer.   See   "Description  of  the  Preferred   Securities--Distribution   of
Debentures."

         Hvide has, through the Guarantee,  the Declaration,  the Debentures and
the Indenture (each, as defined herein), taken together,  fully, irrevocably and
unconditionally  guaranteed all of the Issuer's  obligations under the Preferred
Securities.  See  "Description  of the  Guarantee,"  "Hvide  Capital  Trust" and
"Description of the  Debentures."  The Guarantee of Hvide guarantees the payment
of  Distributions  and payments on  liquidation  or  redemption of the Preferred
Securities,  but only in each case to the extent of funds held by the Issuer, as
described herein (the "Guarantee"). See "Description of the Guarantee." If Hvide
does not make interest payments on the Debentures held by the Issuer, the Issuer
will have insufficient  funds to pay Distributions on the Preferred  Securities.
The Guarantee does not cover payment of  Distributions  when the Issuer does not
have  sufficient  funds to pay such  Distributions.  In such event,  a holder of
Preferred  Securities may institute a legal proceeding directly against Hvide to
enforce payment under the Debentures of such  Distributions to such holder.  The
obligations of Hvide under the Guarantee are  subordinate and junior in right of
payment to all other liabilities of Hvide and rank pari passu with any guarantee
now or hereafter entered into by Hvide in respect of any preferred or preference
stock   of   any    affiliate    of    Hvide.    See    "Description    of   the
Debentures--Subordination."

         The  Debentures are  subordinate  and junior in right of payment to all
Senior Debt (as defined herein) of Hvide.  The terms of the Debentures  place no
limitation  on the amount of Senior  Debt that may be  incurred  by Hvide or the
amount of indebtedness that may be incurred by its subsidiaries.  As of June 30,
1997,  Hvide had outstanding  $38.8 million of Senior Debt.  Hvide will have the
right from time to time on or after July 2, 2000 to redeem, in whole or in part,
the Debentures at the redemption  prices set forth herein.  See  "Description of
the Debentures--Mandatory Redemption" and "--Optional Redemption."

Prospectus and in the documents incorporated herein by reference.

         Hvide (pronounced "vee-dah") provides marine support and transportation
services  in the U.S.  domestic  trade  and in  selected  international  markets
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 and, as a
result of a May 1997  acquisition,  is one of the largest  operators of offshore
energy support vessels in the Arabian Gulf. 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. In
addition,  the  Company  has a 2.4%  interest,  and  options to acquire up to an
additional  72.6%  interest,  in five  double-hull  petroleum  product  carriers
currently under construction for delivery during 1998 and 1999.

                                        basis,  to guarantee the payment in full
                                        of (i) the Distributions  payable by the
                                        Issuer on the Preferred  Securities,  if
                                        and to the  extent  the Issuer has funds
                                        on hand  available  therefor,  (ii)  the
                                        redemption    price    (including    all

                                        The   Guarantee   will   constitute   an
                                        unsecured  obligation  of Hvide and will
                                        rank  subordinate and junior in right of

                                        of interest  payments may extend  beyond
                                        the stated  maturity of the  Debentures.
                                        Accordingly,  Distribution  payments  on
                                        the  Preferred  Securities  may  not  be
                                        deferred  beyond the stated  maturity of
                                        the Debentures. If Hvide defers interest
                                        payments   longer   than  one   quarter,
                                        subject to certain  exceptions,  it will
                                        be prohibited  from paying  dividends on
                                        any  of its  capital  stock  and  making
                                        certain other restricted  payments until
                                        quarterly  interest payments are resumed
                                        and all  accumulated and unpaid interest
                                        on the  Debentures  is brought  current.
                                        Hvide  has the  right  to  make  partial
                                        payments  of  such  interest   during  a
                                        deferral  of  interest   payments.   The
                                        Debentures are  convertible  into shares
                                        of  Hvide  Class A  Common  Stock at the

                                 RISK FACTORS

         Prospective  purchasers  of the  Preferred  Securities or Hvide Class A
Common Stock should carefully review the information contained elsewhere in this
Prospectus and should particularly consider the following matters.

Ranking of Subordinate Obligations Under the Guarantee and the Debentures

         The  obligations  of Hvide under the Guarantee  issued by Hvide for the
benefit  of  the  holders  of  Preferred   Securities  are  unsecured  and  rank
subordinate and junior in right of payment to all other liabilities of Hvide and
pari passu with any guarantee now or hereafter  entered into by Hvide in respect
of any preferred or preference  stock of any affiliate of Hvide. The obligations
of Hvide under the Debentures are  subordinate and junior in right of payment to
all present and future Senior Debt. As of June 30, 1997,  Hvide had  outstanding
$38.8 million of Senior Debt (excluding  accounts payable and accrued  expenses,
deferred income taxes and other  liabilities).  The ability of the Issuer to pay
amounts due on the Preferred  Securities is solely  dependent  upon Hvide making
payments on the  Debentures as and when  required.  Neither the  Indenture,  the
Guarantee nor the Trust Agreement places any limitation on the amount of secured
or unsecured debt,  including Senior Debt, that may be incurred by Hvide and its
subsidiaries.  See "Description of the  Guarantee--Status  of the Guarantee" and
"Description of the Debentures--Subordination."

Structural Subordination

         The  Debentures  are   obligations  of  Hvide   exclusively.   Since  a
substantial portion of Hvide's operations are conducted through subsidiaries,  a
significant  portion  of Hvide's  cash flow and,  consequently,  its  ability to
service debt,  including the  Debentures,  is dependent upon the earnings of its
subsidiaries  and the  transfer of funds by those  subsidiaries  to Hvide in the
form of dividends or other transfers,  supplemented with borrowings. The ability
of these  subsidiaries  to pay  dividends  to Hvide in the  future is subject to
restrictions  contained in indentures  and other  financing  agreements by which
such  subsidiaries  are bound. See  "--Restrictive  Covenants Under Hvide Credit
Facility."

         In addition,  creditors of Hvide's  subsidiaries would be entitled to a
claim  on the  assets  of  such  subsidiaries  prior  to any  claims  by  Hvide.
Consequently, in the event of a liquidation or reorganization of any subsidiary,
creditors  of  such  subsidiary  are  likely  to be  paid  in  full  before  any
distribution  is made to  Hvide,  except  to the  extent  that  Hvide  itself is
recognized as a creditor of such  subsidiary,  in which case the claims of Hvide
would  still be  subordinate  to any  security  interest  in the  assets of such
subsidiary and any indebtedness of such subsidiary senior to that held by Hvide.
As of June 30, 1997, the aggregate indebtedness  (excluding accounts payable and
accrued  expenses,   deferred  income  taxes  and  other   liabilities)  of  the
consolidated   subsidiaries  of  Hvide  was  approximately  $38.8  million.  See
"Description of the Preferred Securities--Distributions" and "Description of the
Debentures--Option to Extend Interest Payment Period."

Option to Extend Interest Payment Period; Tax Consequences; Trading Price

         So  long  as  there  is  no  continuing  event  of  default  under  the
Debentures,  Hvide has the right  under the  Indenture  to defer the  payment of
interest  on the  Debentures  at any time or from time to time for a period  not
exceeding  20  consecutive  quarters  with  respect  to each  Extension  Period,
provided that no

                                                        13

<PAGE>



Extension  Period may extend beyond the stated maturity of the Debentures.  Upon
the termination of any Extension Period and the payment of all amounts then due,
Hvide may  select a new  Extension  Period and  terminate  the  payments  of all
amounts then due, subject to the requirements described herein. As a consequence
of any such deferral, quarterly Distributions on the Preferred Securities by the
Issuer will be deferred (and the amount of Distributions to which holders of the
Preferred  Securities  are entitled will  accumulate  additional  Distributions)
during any such Extension Period.

         During any  Extension  Period,  holders of  Preferred  Securities  will
continue to accrue income (in the form of original issue discount) in respect of
their pro rata share of the deferred  interest  allocable to the Debentures held
by the Issuer for United  States  federal  income tax purposes.  As a result,  a
holder of  Preferred  Securities  will  include  such income in gross income for
United States federal income tax purposes in advance of the receipt of cash, and
will not receive  the cash  related to such income from the Issuer if the holder
disposes of the Preferred Securities prior to the record date for the payment of
Distributions.  See "Certain  Federal  Income Tax  Consequences--Original  Issue
Discount." Moreover,  if a holder of Preferred Securities converts its Preferred
Securities  into Hvide Class A Common  Stock  during an  Extension  Period,  the
holder will not  receive  any cash  related to the  deferred  distribution.  See
"Description of the Preferred Securities--Distributions."

         Although  Hvide has no current  intention  of  exercising  its right to
defer  payments of interest by  extending  the  interest  payment  period on the
Debentures,  should Hvide elect to exercise such right in the future, the market
price of the Preferred  Securities is likely to be adversely affected.  A holder
that disposes of its Preferred Securities during an Extension Period, therefore,
might not receive the same return on its  investment as a holder that  continues
to hold its Preferred  Securities.  In addition, as a result of the existence of
Hvide's  right to defer  interest  payments,  the market price of the  Preferred
Securities  (which represent  preferred  undivided  beneficial  interests in the
Debentures)  may be more volatile than the market prices of other  securities on
which original issue discount accrues that are not subject to such deferrals.

Special Event Exchange or Redemption

         Upon certain circumstances following the occurrence and continuation of
a Special Event (as defined herein),  the Preferred  Securities are also subject
to (i) exchange in whole or in part,  in the manner  described  herein,  for the
Debentures and  termination of the Trust or (ii) redemption in whole or in part,
on or after July 2, 2000 in the case of a Tax  Event.  See  "Description  of the
Preferred Securities--Special Event Exchange or Redemption."

         There  can  be no  assurance  as to the  market  prices  for  Preferred
Securities  or  Debentures  that may be  distributed  in exchange for  Preferred
Securities if a liquidation of the Issuer occurs or if the Preferred  Securities
are exchanged for Debentures in connection  with a Special  Event.  Accordingly,
the Preferred  Securities that an investor may purchase or the Debentures that a
holder of  Preferred  Securities  may receive on  liquidation  of the Issuer may
trade  at a  discount  to the  price  that the  investor  paid to  purchase  the
Preferred Securities offered hereby. Because holders of Preferred Securities may
receive  Debentures on dissolution of the Issuer or if the Preferred  Securities
are exchanged for  Debentures in connection  with a Special  Event,  prospective
purchasers of Preferred  Securities are also making an investment  decision with
respect to the  Debentures  and  should  carefully  review  all the  information
regarding the Debentures  contained  herein.  See  "Description of the Preferred
Securities--Special  Event  Exchange  or  Redemption"  and  "Description  of the
Debentures--General."

Limited Rights under the Guarantee

         Hvide's  guarantee  of  payments  of  Distributions  on  the  Preferred
Securities,  of  payment of the  redemption  price of any  Preferred  Securities
called  for  redemption,  and of payment of the  liquidation  preference  of the
Preferred Securities upon liquidation of the Trust is limited to the extent that
the Trust has  funds on hand  available  for such  payment  and,  in the case of
liquidation, to the assets of the Trust available for distribution.

         If Hvide were to default on its obligation to pay amounts payable under
the  Debentures,  the Issuer would lack funds for the payment of Distribution or
amounts payable on redemption of the Preferred Securities or otherwise,  and, in
such event,  holders of the Preferred  Securities would not be able to rely upon
the  Guarantee  for payment of such  amount.  Instead,  in the event a Debenture
Event of Default  shall have occurred and be  continuing,  a holder of Preferred
Securities  would be required to rely on its  enforcement  by the Trustee of its
rights as registered holder of the Debenture against Hvide pursuant to the terms
of the Indenture and the Debentures.  If, however, such event is attributable to
the failure of Hvide to pay interest on or principal  of the  Debentures  on the
payment  date on  which  such  payment  is due and  payable,  then a  holder  of
Preferred  Securities  may  directly  institute a proceeding  against  Hvide for
enforcement  of payment to such holder of the  interest on or  principal of such
Debentures  having  a  principal  amount  equal  to  the  aggregate  liquidation
preference of the Preferred  Securities of such holder (a "Direct  Action").  In
connection  with such Direct  Action,  Hvide will be subrogated to the rights of
such holder of Preferred  Securities  under the Declaration to the extent of any
payment  made by Hvide to such  holder of  Preferred  Securities  in such Direct
Action. Except as set forth herein,  holders of Preferred Securities will not be
able  to  exercise  directly  any  other  remedy  available  to the  holders  of
Debentures or assert directly any other rights in respect of the Debentures. See
"Description  of the  Preferred  Securities--Enforcement  of  Certain  Rights by
Holders  of  Preferred   Securities,"   "Description   of  the   Guarantee"  and
"Description  of the  Debentures--Debenture  Events of Default." The Declaration
provides that each holder of Preferred  Securities by acceptance  thereof agrees
to the provisions of the Guarantee and the Indenture.

Limited Voting Rights

         Holders of the Preferred  Securities  have limited voting  rights.  The
voting rights that they have are primarily  limited to directing the  activities
of the  Trustee  as the  holder  of the  Debentures.  Holders  of the  Preferred
Securities  are not  entitled to vote to  appoint,  remove or replace the Issuer
Trustee,  which  voting  rights  are  vested  exclusively  in Hvide.  The Issuer
Trustees and Hvide may amend the  Declaration  without the consent of holders of
Preferred  Securities  to ensure that the Issuer will be  classified  for United
States  federal  income tax  purposes  as a grantor  trust  even if such  action
adversely  affects  the  interests  of such  holders.  See  "Description  of the
Preferred Securities--Voting Rights; Amendment of the Declaration."

Proposed Tax Legislation

         As a part of  President  Clinton's  Fiscal  1998 Budget  Proposal,  the
Treasury  Department proposed  legislation that, among other things,  would have
treated as equity for United  States  federal  income tax purposes  certain debt
instruments that are not shown as indebtedness on the consolidated balance sheet
of the issuer.  Although this  proposal was not included in the tax  legislation
ultimately  enacted,  there can be no assurance that such a proposal will not be
enacted in the future, that such future legislation would not have a retroactive
effective  date and that such future  legislation  would not prevent  Hvide from
deducting interest on the Debentures. Such an event would constitute a Tax Event
and would permit the Issuer to exchange the Preferred Securities, in whole or in
part,  for the  Debentures  or  redeem,  in  whole  or in  part,  the  Preferred
Securities and Debentures.

Potential Reduction of Payments to Non-United States Holders for United States 
Tax Withholding Requirements

         In the event that any United States taxes, duties or other governmental
charges are  required to be deducted or withheld  from any  payments by Hvide to
holders of Preferred Securities that are Non-U.S. Persons, neither Hvide nor the
Issuer will be  required  to pay any  additional  amounts to such  holders  and,
therefore, any such taxes, duties or charges will reduce the amounts received by
such  holders.  See "Certain  Federal  Income Tax  Consequences--Certain  United
States Tax Consequences to Non-United States Holders."

Absence of Public Market for the Preferred Securities

         Although the Preferred  Securities  are currently  traded in the PORTAL
market,  there  can  be no  assurance  that  such  market  will  continue  to be
maintained.  If an  active  market  for the  Preferred  Securities  fails  to be
sustained,  the trading  price of the  Preferred  Securities  could be adversely
affected.

Trading Price of Preferred Securities

         The  Preferred  Securities  may  trade at a price  that  does not fully
reflect the value of accrued but unpaid  interest with respect to the underlying
Debentures.  A holder disposing of Preferred Securities between record dates for
payments of  distributions  thereon will be required for United  States  federal
income tax  purposes to include  accrued but unpaid  interest on the  Debentures
through the date of  disposition  in income as ordinary  income (i.e.,  original
issue  discount),  and to add  such  amount  to the  adjusted  tax  basis in the
holder's Preferred Securities.  To the extent the selling price is less than the
holder's  adjusted tax basis (which will include,  in the form of original issue
discount,  all accrued but unpaid  interest),  a holder will recognize a capital
loss. Subject to certain limited exceptions, capital losses cannot be applied to
offset  ordinary  income for United  States  federal  income tax  purposes.  See
"Certain Federal Income Tax Consequences--Sales of Preferred Securities."

Restrictive Covenants under Hvide Credit Facility
   
         The terms of the  Company's  Credit  Facility  (as defined  herein) (i)
require the Company to meet certain  financial tests,  including tests requiring
the maintenance of minimum  leverage ratios,  debt service coverage ratios,  and
indebtedness to tangible net worth ratios; (ii) limit the creation or incurrence
of certain liens;  (iii) limit the incurrence of additional  indebtedness;  (iv)
restrict the Company from making

                                                        16

certain investments;  (v) restrict certain payments,  including dividends,  with
respect to shares of any class of capital stock;  (vi) restrict  modification of
the terms of the  Preferred  Securities  (as  defined  herein),  and in  certain
circumstances  the  repayment,   redemption,  or  repurchase  of  the  Preferred
Securities;  and (vii) limit  certain  corporate  acts of the  Company,  such as
making  certain  dispositions  of assets,  and entering  into  certain  types of
business  transactions,   including  certain  mergers  and  acquisitions.   Such
provisions could adversely  affect the Company's  ability to pursue its strategy
of growth through acquisitions.  Borrowings under the Credit Facility constitute
Senior Debt for purposes of the Indenture.
    
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

                                                        17

<PAGE>



recent  years,  oil and natural gas prices,  and therefore the level of offshore
drilling and  exploration  activity,  have been extremely  volatile.  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. 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.

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,  the Oil Pollution Act of 1990 ("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.

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 vessels or acquiring new or used vessels.

Risks of International Operations

         The Company derives revenues from international operations. The Company
currently  operates 41 vessels in  international  waters,  including the Arabian
Gulf  and  the  waters  offshore  Southeast  Asia,  Egypt  and  Cameroon.  Risks
associated  with operating in  international  markets  include  vessel  seizure,
foreign  exchange  restrictions  and currency  fluctuations,  foreign  taxation,
political   instability,   foreign  and  domestic  monetary  and  tax  policies,
expropriation, nationalization,  nullification, modification or renegotiation of
contracts,  war and civil  disturbances or other risks that may limit or disrupt
markets.

                                                        18

<PAGE>



Additionally,  the ability of the Company to compete in the international marine
support  and  transportation   market  may  be  adversely  affected  by  foreign
government  regulations  that favor or require the awarding of such contracts to
local persons,  or by regulations  requiring  foreign persons to employ citizens
of, or purchase  supplies  from, a  particular  jurisdiction.  Furthermore,  the
Company's foreign subsidiaries may face governmentally imposed restrictions from
time to time on their ability to transfer  funds to the Company.  No predictions
can be made as to what foreign governmental regulations may be applicable to the
Company's operations in the future.

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.  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 of Common Stock; Possible Inability to Convert 
Preferred Securities and Debentures

         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.  Although  the
Company's  Articles of Incorporation  contain  provisions  limiting  non-citizen
ownership of its capital stock (see "Description of Hvide 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.  See  "Description  of Hvide  Capital
Stock."

         As a result of this limitation  upon the  non-citizen  ownership of the
Company's  outstanding  capital stock,  any non-citizen  holder of the Preferred
Securities  will, to the extent such conversion would cause more than 25% of the
Company's  outstanding  Common Stock held by non-citizens,  be unable to convert
its Preferred Securities or Debentures into shares of Hvide Class A Common Stock
and will be required to sell its  Preferred  Securities  or  Debentures  to U.S.
citizens in order to realize the economic benefits, if any, of conversion.

Risks of Acquisition Strategy

         As  the  marine  support  and   transportation   market   continues  to
consolidate,  a key  component of the Company's  business  strategy is to pursue
selected  acquisitions of complementary  assets and businesses.  Since 1994, the
Company has  completed a number of  significant  acquisitions.  Possible  future
acquisitions may be for purchase prices significantly higher than those paid for
recent and pending  acquisitions.  Certain risks are inherent in an  acquisition
strategy, such as increasing leverage and debt service requirements, which could
adversely affect the Company's  operating results.  The success of any completed
acquisition  will  depend  in  part  on  the  Company's   ability  to  integrate
effectively the acquired  business into the Company.  The process of integrating
such acquired  businesses may involve unforeseen  difficulties and may require a
disproportionate  amount of management's  attention and the Company's  financial
and other resources.  No assurance can be given that the Company will be able to
continue to identify additional suitable  acquisition  opportunities,  negotiate
acceptable  terms,  obtain financing for  acquisitions on satisfactory  terms or
successfully  acquire  identified  targets.  The  Company's  failure  to achieve
consolidation  savings,  to incorporate the acquired  businesses and assets into
its existing operations  successfully or to minimize any unforeseen  operational
difficulties could have a material adverse effect on the Company.

Legal Proceedings

         The  Company's  chemical  carrier  Seabulk  America is the subject of a
pending legal proceeding  which, if determined  adversely to the Company,  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.

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,

                                                        20

<PAGE>



of which each share is entitled to ten votes with  respect to such  matters.  J.
Erik Hvide, the Company's Chairman,  together with certain trusts of which he is
the trustee  (the "Hvide  Trusts"),  beneficially  own 10,000  shares of Class A
Common  Stock  and  1,496,466  shares  of Class B Common  Stock,  and a group of
investors (the "Investor  Group"),  which in September 1994 purchased  shares of
Common Stock and certain of the Company's  debt  securities,  beneficially  owns
874,668  shares of Class A Common Stock and  1,409,999  shares of Class B Common
Stock.  Mr.  Hvide  (together  with the Hvide  Trusts)  and the  Investor  Group
therefore  own  shares  that  represent  9.9% and  15.0%,  respectively,  of the
outstanding  shares of Common Stock and each owns shares  representing  36.2% of
the voting power of all Common  Stock.  Accordingly,  Mr. Hvide and the Investor
Group, acting together,  are 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 (as defined  herein) and the  Investor
Group have  entered  into an agreement  that  currently  gives them the right to
nominate eight and up to two persons,  respectively,  to the Company's  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  "Description  of  Hvide  Capital  Stock--Certain
Provisions of Articles of Incorporation and Bylaws." 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 Hvide 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.  All of the shares of Class B Common
Stock owned by Mr. Hvide, the Hvide Trusts, and the Investor Group are currently
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. 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 Hvide  Capital  Stock--Shareholders
Agreement."  Certain  directors,  officers,  and  employees  of the Company hold
options  to  purchase  827,325  shares of Class A Common  Stock.  Moreover,  the
Company may issue shares of Common Stock in connection with future acquisitions.

                                HVIDE CAPITAL TRUST

         Hvide Capital Trust is a statutory business trust formed under Delaware
law  pursuant  to (i) a  declaration  of trust (the  "Declaration")  executed by
Hvide,  as sponsor of the Trust,  and the  trustees of the Issuer  (the  "Issuer
Trustees")  and (ii) the filing of a certificate  of trust with the Secretary of
State of the State of  Delaware.  The  Company  holds  Common  Securities  in an
aggregate  liquidation  amount equal to 3.0% of the total capital of the Issuer.
The Common  Securities  rank pari passu,  and payment is made  thereon pro rata,
with the Preferred  Securities,  except that, upon the occurrence and during the
continuance  of an event of  default  under the  Declaration,  the rights of the
holders of the Common  Securities  to  payment in respect of  distributions  and
payments upon liquidation,  redemption and otherwise will be subordinated to the
rights of the  holders  of the  Preferred  Securities.  The  assets of the Trust
consist  principally  of the  Debentures.  The Issuer  exists for the  exclusive
purpose  of  (i)  issuing  the  Preferred   Securities  and  Common   Securities
representing  undivided  beneficial  interests in the assets of the Trust,  (ii)
investing the gross proceeds of the Preferred  Securities and Common  Securities
in the Debentures and (iii) engaging in only those other activities necessary or
incidental thereto.

         Pursuant to the Declaration, the number of Issuer Trustees currently is
five. Three of the Issuer Trustees (the "Company  Trustees") are individuals who
are employees or officers of or who are affiliated with Hvide. The fourth Issuer
Trustee  is a  financial  institution  that  is  unaffiliated  with  Hvide  (the
"Trustee").  The fifth Issuer  Trustee is an entity that maintains its principal
place of business in the State of Delaware (the "Delaware Trustee").  Currently,
The Bank of New York, a New York banking  corporation,  is the Trustee,  and its
affiliate, The Bank of New York (Delaware),  a Delaware banking corporation,  is
the Delaware  Trustee  until,  in each case,  removed or replaced by the Company
Trustees.  The  Bank of New  York  also  acts as  indenture  trustee  under  the
Guarantee  (the  "Guarantee  Trustee") and under the Indenture  (the  "Indenture
Trustee").  See "Description of the Guarantee" and "Description of the Preferred
Securities."

         The  Trustee  holds  title to the  Debentures  for the  benefit  of the
holders of the  Preferred  Securities  and has the power to exercise all rights,
powers and privileges  under the Indenture as the holder of the  Debentures.  In
addition,  the Trustee maintains exclusive control of a segregated  non-interest
bearing  bank  account (the  "Property  Account")  to hold all payments  made in
respect  of  the  Debentures  for  the  benefit  of  the  holders  of  Preferred
Securities.  Hvide,  as the  direct  or  indirect  holder  of all of the  Common
Securities,  has the right to  appoint,  remove  or  replace  any of the  Issuer
Trustees  and to increase or decrease  the number of Issuer  Trustees,  provided
that the number of Issuer Trustees shall be at least

                                                        23

three, the majority of which shall be Company Trustees.  Hvide paid all fees 
and expenses related to the Trust and the Original Offering.  See "Description 
of the Debentures."

         The  rights  of the  holders  of the  Preferred  Securities,  including
economic  rights,  rights to information  and voting rights,  if any, are as set
forth in the  Declaration  and the Delaware  Business Trust Act, as amended (the
"Trust Act").  See  "Description of the Preferred  Securities." The Declaration,
the Indenture and the Guarantee  also  incorporate by reference the terms of the
Trust  Indenture  Act of 1939,  as amended (the "Trust  Indenture  Act").  It is
expected that, at the time the  registration  statement of which this Prospectus
is part becomes effective, the Declaration, the Indenture and the Guarantee will
be qualified  under the Trust  Indenture  Act. The Trustee will act as Indenture

                             THE COMPANY

         Hvide (pronounced "vee-dah") provides marine support and transportation
services  in the U.S.  domestic  trade  and in  selected  international  markets
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 and, as a
result of a May 1997  acquisition,  is one of the largest  operators of offshore
energy support vessels in the Arabian Gulf. 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. In
addition,  the  Company  has a 2.4%  interest,  and  options to acquire up to an
additional  72.6%  interest,  in five  double-hull  petroleum  product  carriers
currently under construction for delivery during 1998 and 1999.
   
Recent Developments.  In August 1997 the Company entered into a letter of intent
to acquire all of the outstanding stock of Bay Transportation  Corporation ("Bay
Transportation").  Bay  Transportation  is the primary provider of harbor towing
services in the Port of Tampa and also charters  tugs to other  operators in the
Ports of San Francisco and Long Beach,  California.  Its 14-vessel fleet,  which
includes six tractor  tugs,  will  increase to 30 the number of tugs operated by
the  Company.  Consideration  payable  by the  Company  in  connection  with the
acquisition, which the Company anticipates will be completed in October 1997, is
expected to include cash of $41 million and the assumption of approximately  $15
million of debt.
    
         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 Selling  Holders will receive all of the proceeds  from any sale of
the Offered  Securities.  Neither  the  Company  nor the Trust will  receive any
proceeds therefrom.

                            ACCOUNTING TREATMENT

         The financial statements of the Issuer are included in the consolidated
financial  statements  of Hvide  with  the  Preferred  Securities  shown on such
consolidated  financial  statements as  "Company-obligated  mandatory redeemable
preferred  securities  issued by a consolidated  subsidiary." The sole assets of
the Issuer will be the 6 1/2% Convertible Subordinated Debentures due 2012.

                       DESCRIPTION OF THE PREFERRED SECURITIES

         This summary of certain provisions of the Preferred  Securities and the
Declaration  does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all the  provisions of the  Declaration (a copy
of which has been  filed as an exhibit to the  registration  statement  of which
this  Prospectus  is part),  the Trust Act and the Trust  Indenture Act which is
incorporated by reference in the Declaration.  Wherever particular defined terms
of the Declaration are referred to herein,  such defined terms are  incorporated
herein by reference.

General

         Pursuant  to the terms of the  Declaration,  the  Issuer  Trustees,  on
behalf of the Issuer, issued the Preferred Securities and the Common Securities.
The Preferred  Securities  represent preferred undivided beneficial interests in
the assets of the Issuer and the Common  Securities  represent  common undivided
beneficial  interests in the assets of the Issuer.  All of the Common Securities
are owned by Hvide.  The Preferred  Securities rank pari passu, and payments are
made thereon pro rata,  with the Common  Securities  except as  described  under
"--Subordination  of Common  Securities." Legal title to the Debentures are held
by the  Trustee  in  trust  for the  benefit  of the  holders  of the  Preferred
Securities and Common  Securities.  The Declaration does not permit the issuance
by the Issuer of any  securities  other than the  Preferred  Securities  and the
Common  Securities or the  incurrence  of any  indebtedness  by the Issuer.  The
payment of  Distributions  out of money held by the Issuer,  and  payments  upon
redemption  of the  Preferred  Securities  or  liquidation  of the  Issuer,  are
guaranteed  by  Hvide  to  the  extent  described  under   "Description  of  the
Guarantee."  The  Guarantee  is held by The Bank of New York,  as the  Guarantee
Trustee,  for the  benefit  of the  holders  of the  Preferred  Securities.  The
Guarantee does not cover payment of Distributions  when the Issuer does not have
sufficient available funds to pay such Distributions.  The remedy of a holder of
Preferred  Securities  in such an  event is as  described  herein  in  "--Voting
Rights; Amendment of the Declaration."

Distributions

         Distributions  on the  Preferred  Securities  are payable at the annual
rate of 6 1/2% of the  liquidation  preference  of $50 per  Preferred  Security.
Distributions  will  accumulate  from the date of the  original  issuance of the
Preferred  Securities  and will be  payable  quarterly  in arrears on January 1,
April 1,  July 1 and  October  1 of each  year on the  applicable  record  date,
commencing October 1, 1997 when, as and if available for payment by the Trustee,
except as otherwise described below. The amount of Distributions payable for any
period will be computed on the basis of a 360-day year of twelve 30-day  months.
In the event that any date on which  Distributions  are payable on the Preferred
Securities  is not a Business Day, the payment of the  Distributions  payable on
such date will be made on the next  succeeding  day that is a  Business  Day and
without any  additional  Distributions  or other  payment in respect of any such
delay,  except that,  if such  Business Day is in the next  succeeding  calendar
year, such payment shall be made on the immediately  preceding  Business Day, in
each case with the same  force and effect as if made on such  record  date (each
date on which  Distributions  are payable in accordance  with the  foregoing,  a
"Distribution  Date"). A "Business Day" shall mean any day other than a Saturday
or a Sunday, or a day on which banking  institutions in the City of New York are
authorized  or required by law or executive  order to remain  closed or a day on
which the  corporate  trust  office of the Trustee or the  Indenture  Trustee is
closed for business.


                                                        27

<PAGE>



         So  long  as  no  Debenture  Event  of  Default  has  occurred  and  is
continuing,  Hvide has the right  under the  Indenture  to defer the  payment of
interest  on the  Debentures  at any time or from time to time for a period  not
exceeding  20  consecutive  quarters  with  respect  to each  Extension  Period,
provided that no Extension  Period may extend beyond the stated  maturity of the
Debentures.  As a consequence of any such election,  quarterly  Distributions on
the  Preferred  Securities  will be  deferred  by the  Issuer  during  any  such
Extension Period. Distributions to which holders of the Preferred Securities are
entitled will accumulate additional  Distributions thereon at the rate per annum
set forth herein,  compounded  quarterly from the relevant payment date for such
Distributions.  The term  "Distributions"  as used herein shall include any such
additional  Distributions.  During any such Extension Period, Hvide may not, and
may not cause any of its  subsidiaries  to, (i) declare or pay any  dividends or
distributions on, or redeem,  purchase,  acquire,  or make a liquidation payment
with  respect  to,  any of  Hvide's  capital  stock or (ii) make any  payment of
principal,  interest or premium,  if any, on or repay,  repurchase or redeem any
debt securities  (including  guarantees of  indebtedness  for money borrowed) of
Hvide  that rank pari passu with or junior to the  Debentures  (other  than with
respect  to  both  (i) and  (ii))  (a) any  dividend,  redemption,  liquidation,
interest,  principal or guarantee  payment by Hvide where the payment is made by
way of securities  (including capital stock) that rank pari passu with or junior
to the securities on which such  dividend,  redemption,  interest,  principal or
guarantee payment is being made, (b) payments under the Guarantee, (c) purchases
of Hvide Class A Common  Stock  related to the  issuance of Hvide Class A Common
Stock  under  any of  Hvide's  benefit  plans  for its  directors,  officers  or
employees, (d) as a result of a reclassification of Hvide's capital stock or the
exchange  or  conversion  of one  series or class of Hvide's  capital  stock for
another  series or class of  Hvide's  capital  stock,  and (e) the  purchase  of
fractional  interests  in  shares  of  Hvide's  capital  stock  pursuant  to the
conversion or exchange  provisions  of such capital stock or the security  being
converted or exchanged).  Prior to the termination of any such Extension Period,
Hvide may further extend the interest payment period, provided that no Extension
Period may exceed 20 consecutive  quarters or extend beyond the stated  maturity
of the  Debentures.  Upon the  termination of any such Extension  Period and the
payment of all amounts then due on any Interest Payment Date, Hvide may elect to
begin a new Extension  Period.  See  "Description of the  Debentures--Option  to
Extend   Interest    Payment   Period"   and   "Certain   Federal   Income   Tax
Consequences--Original Issue Discount."

         Hvide has no current  intention to exercise its right to defer payments
of interest by extending the Interest Payment Period on the Debentures.

         Distributions with respect to the Preferred  Securities must be paid on
the dates  payable to the extent  that the  Issuer has funds  available  for the
payment of such  Distributions in the Property Account.  The funds of the Issuer
available  for  distribution  to holders  of the  Preferred  Securities  will be
limited to  payments  under the  Debentures  in which the Issuer will invest the
proceeds from the issuance and sale of the Preferred  Securities  and the Common
Securities. See "Description of the Debentures." If Hvide does not make interest
payments on such  Debentures,  the Trustee will not have funds  available to pay
Distributions on the Preferred Securities.  The payment of Distributions (if and
to the extent the Issuer  has funds on hand  available  for the  payment of such
Distributions  and cash sufficient to make such payments) is guaranteed by Hvide
as set forth herein under "Description of the Guarantee."

         Distributions  on the  Preferred  Securities  will  be  payable  to the
holders  thereof as they appear on the  register  of the Issuer on the  relevant
record  dates,  which shall be the fifteenth day (whether or not a Business Day)
next  preceding  the  relevant  distribution  date.  As  long  as the  Preferred
Securities  remain  in  book-entry  form,  subject  to any  applicable  laws and
regulations and the provisions of the Trust

                                                        28

Agreement,  each  such  payment  will  be  made as  described  under  "--Certain
Book-Entry Procedures for Global Certificates."

Conversion Rights

         The  Preferred   Securities  are  convertible  at  any  time  beginning
September  25, 1997  through the close of business on the  Business Day prior to
the maturity  date of the  Debentures  (or, in the case of Preferred  Securities
called for redemption,  prior to the close of business on the Business Day prior
to the Redemption Date) (the "Conversion  Expiration Date") at the option of the
holder thereof and in the manner described  below,  into shares of Hvide Class A
Common  Stock at an initial  conversion  rate of 1.7544  shares of Hvide Class A
Common Stock for each  Preferred  Security  (equivalent  to a purchase  price of
$28.50  per share of Hvide  Class A Common  Stock),  subject  to  adjustment  as
described under "--Conversion Price Adjustments" below.

         A holder of Preferred  Securities  wishing to exercise  its  conversion
right shall  surrender such Preferred  Securities,  together with an irrevocable
conversion  notice to the Trustee,  as Conversion  Agent, or to such other agent
appointed for such purpose, which shall, on behalf of such holder,  exchange the
Preferred  Securities for a portion of the Debentures  and  immediately  convert
such Debentures into Hvide Class A Common Stock. So long as a book-entry  system
for  the  Preferred  Securities  is  in  effect,  however,  the  procedures  for
converting the Preferred Stock that are in the form of Global  Certificates into
shares of Hvide  Class A Common  Stock  will be as  described  under  "--Certain
Book-Entry  Procedures for Global Certificate." Hvide's delivery upon conversion
of the  fixed  number of shares of Hvide  Class A Common  Stock  into  which the
Debentures are convertible  (together with the cash payment,  if any, in lieu of
any fractional  share) shall be deemed to satisfy Hvide's  obligation to pay the
principal  amount at maturity of the portion of the  Debentures so converted and
any unpaid interest  accrued on such Debentures at the time of such  conversion.
For a discussion  of the taxation of such an exchange to holders,  including the
possibility that holders who exchange their Preferred Securities for Hvide Class
A Common Stock may be subject to additional income tax to the extent accrued but
unpaid  interest on the Debentures  upon a conversion  into Hvide Class A Common
Stock,  see "Certain  Federal Income Tax  Consequences--Conversion  of Preferred
Securities  into Hvide Class A Common  Stock."  Holders may obtain copies of the
required form of the conversion notice from the Conversion Agent.

         Accumulated Distributions will not be paid on Preferred Securities that
are converted;  provided,  however, holders of Preferred Securities at the close
of business on a  Distribution  payment  record date will be entitled to receive
the  Distribution  payable,  in  cash,  on  such  Preferred  Securities  on  the
corresponding  Distribution  payment date notwithstanding the conversion of such
Preferred Securities on or subsequent to such Distribution record date but prior
to such  Distribution  payment  date.  Except  as  provided  in the  immediately
preceding sentence, the Issuer will make no payment or allowance for accumulated
and unpaid  Distributions,  whether or not in arrears,  on  converted  Preferred
Securities.  Hvide will make no payment or allowance for dividends on the shares
of Hvide Class A Common Stock issued upon such conversion.  Each conversion will
be deemed to have been  effected  immediately  prior to the close of business on
the day on which proper notice was received by the Conversion Agent.

         Shares  of  Hvide  Class A  Common  Stock  issued  upon  conversion  of
Preferred Securities will be validly issued,  fully paid and non-assessable.  No
fractional  shares of Hvide  Class A Common  Stock will be issued as a result of
conversion, but in lieu thereof such fractional interest will be paid in cash.

Factors--Restriction on Foreign Ownership of Common Stock; Possible Inability 
to Convert Preferred Securities and Debentures."

Conversion Price Adjustments

         General.  The conversion price will be subject to adjustment in certain
events including,  without duplication:  (i) the payment of dividends (and other
distributions)  payable exclusively in Hvide common stock on Hvide common stock;
(ii) the  issuance  to all holders of Hvide  common  stock of rights or warrants
entitling  holders of such rights or  warrants  (for a period not  exceeding  45
days) to  subscribe  for or purchase  Hvide  common  stock at less than the then
Current Market Price (as defined herein); (iii) subdivisions and combinations of
Hvide common stock;  (iv) the payment of dividends (and other  distributions) to
all holders of Hvide common stock  consisting  of evidences of  indebtedness  of
Hvide,  securities or capital stock, cash, or assets (but excluding those rights
or warrants  referred to above in clause (ii) and  dividends  and  distributions
paid   exclusively   in  cash);   (v)  the  payment  of  dividends   (and  other
distributions)  on Hvide common stock paid  exclusively  in cash,  excluding (A)
cash  dividends  that do not  exceed  the per share  amount  of the  immediately
preceding  regular  cash  dividend  (as  adjusted  to reflect  any of the events
referred  to in  clauses  (i)  through  (vi) of  this  sentence),  and (B)  cash
dividends if the  annualized  per share amount thereof does not exceed 5% of the
last sale price of Hvide  common  stock,  as  reported  on the  Nasdaq  National
Market, on the trading day immediately preceding the date of declaration of such
dividend  (such  adjustment  being limited to the amount in excess of 5% of such
Current Market Price); and (vi) payment in respect of a tender or exchange offer
(other  than an  odd-lot  offer) by Hvide or any  subsidiary  of Hvide for Hvide
common stock in excess of 110% of the Current Market Price of Hvide common stock
on the trading day next  succeeding  the last date tenders or  exchanges  may be
made pursuant to such tender or exchange offer.

         Hvide  from  time  to time  may  reduce  the  conversion  price  of the
Debentures  (and thus the conversion  price of the Preferred  Securities) by any
amount selected by Hvide for any period of at least 30 days, in which case Hvide
shall give at least 15 days' notice of such reduction. Hvide may, at its option,
make such  reductions in the  conversion  price,  in addition to those set forth
above,  as the Board of Directors of Hvide deems  advisable to avoid or diminish
any  income  tax to holders of Hvide  Class A Common  Stock  resulting  from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated  as such for  income  tax  purposes.  See  "Certain  Federal  Income Tax
Consequences--Adjustment of Conversion Price."

         No adjustment of the conversion price will be made upon the issuance of
any  shares of Hvide  common  stock  pursuant  to any  present  or  future  plan
providing for the reinvestment of dividends or interest payable on securities of
Hvide and the  investment  of  additional  optional  amounts  in shares of Hvide
common stock under any such plan,  or the issuance of any shares of Hvide common
stock or options or rights to purchase  such  shares  pursuant to any present or
future  employee  benefit  plan or program of Hvide or  pursuant  to any option,
warrant, right, or exercisable,  exchangeable or convertible security which does
not  constitute  an issuance to all  holders of Hvide  common  stock (or a class
thereof) of rights or warrants  entitling  holders of such rights or warrants to
subscribe  for or purchase  Hvide common  stock at less than the Current  Market
Price.  There shall also be no adjustment of the conversion price in case of the
issuance  of  any  Hvide  common  stock  (or  securities   convertible  into  or
exchangeable for Hvide common stock), except as specifically described above. If
any action would require  adjustment of the  conversion  price  pursuant to more
than one of the anti-dilution provisions, only one adjustment

                                                        30

<PAGE>



shall be made and such adjustment shall be the amount of adjustment that has the
highest absolute value to holders of the Preferred Securities.  No adjustment in
the conversion  price will be required unless such  adjustment  would require an
increase or decrease of at least 1% of the conversion  price, but any adjustment
that would  otherwise be required to be made shall be carried  forward and taken
into account in any subsequent adjustment.

         Merger,  Consolidation  or Sale of Assets of Hvide.  In the event  that
Hvide is a party to any transaction  (including,  without  limitation,  a merger
other  than a merger  that does not  result in a  reclassification,  conversion,
exchange  or  cancellation  of  Hvide  Class  A  Common  Stock),  consolidation,
continuance,  sale  of  all  or  substantially  all  of  the  assets  of  Hvide,
recapitalization or reclassification of Hvide Class A Common Stock (other than a
change in par value,  or from par value to no par value, or from no par value to
par value or as a result of a subdivision or combination of Hvide Class A Common
Stock) or any compulsory share exchange (each of the foregoing being referred to
as a "Transaction"),  in each case, as a result of which shares of Hvide Class A
Common Stock shall be converted into the right to receive, or shall be exchanged
for, (i) in the case of any  Transaction  other than a  Transaction  involving a
Stock Fundamental  Change (as defined below) (and subject to funds being legally
available for such purpose under applicable law at the time of such conversion),
securities,  cash or other property, each Preferred Security shall thereafter be
convertible  into the kind  and,  in the case of a  Transaction  which  does not
involve a Fundamental Change (as defined herein), amount of securities, cash and
other property  receivable upon the consummation of such Transaction by a holder
of that  number of shares of Hvide  Class A Common  Stock into which a Preferred
Security was convertible  immediately prior to such Transaction,  or (ii) in the
case of a  Transaction  involving a Stock  Fundamental  Change,  each  Preferred
Security shall thereafter be convertible (in the manner  described  herein) into
common stock of the kind  received by holders of Hvide Class A Common Stock (but
in each case after giving effect to any adjustment discussed below relating to a
Fundamental Change if such Transaction  constitutes a Fundamental  Change).  The
holders of Preferred  Securities  will have no voting rights with respect to any
Transaction described in this section.

         If any Fundamental  Change occurs,  then the conversion price in effect
will be adjusted  immediately after such Fundamental  Change as described below.
In addition, in the event of a Stock Fundamental Change, each Preferred Security
shall be convertible solely into common stock of the kind received by holders of
Hvide Class A Common Stock as a result of such Stock Fundamental Change.

         The  conversion  price in the case of any  Fundamental  Change  will be
adjusted immediately after such Fundamental Change:

                  (i) in the case of a Non-Stock  Fundamental Change (as defined
         herein), the conversion price of the Preferred  Securities  immediately
         following  such Non-Stock  Fundamental  Change will be the lower of (A)
         the  conversion  price in effect  immediately  prior to such  Non-Stock
         Fundamental  Change  (after  giving  effect  to any  other  adjustments
         effected  pursuant to the preceding  paragraphs)  or (B) the product of
         (1) the greater of the  Applicable  Price (as  defined  herein) and the
         then  applicable  Reference  Market Price (as defined herein) and (2) a
         fraction, the numerator of which is $50 and the denominator of which is
         (x) the amount of the  redemption  price for one Preferred  Security if
         the redemption date were the date of such Non-Stock  Fundamental Change
         (or, for the twelve-month periods commencing July 2, 1997, July 2, 1998
         and July 2,

                                                        31

         1999 the product of 105.23%, 105.91% and 106.60%,  respectively,  times
         $50) plus (y) any  then-accumulated  and  unpaid  distributions  on one
         Preferred Security; and

                  (ii) in the case of a Stock  Fundamental  Change  (as  defined
         herein), the conversion price of the Preferred  Securities  immediately
         following such Stock Fundamental Change will be the conversion price in
         effect immediately prior to such Stock Fundamental Change (after giving
         effect  to  any   adjustments   effected   pursuant  to  the  preceding
         paragraphs)  as  adjusted by  multiplying  such  conversion  price by a
         fraction of which the numerator  will be the Purchaser  Stock Price and
         the denominator will be the Applicable Price;  provided,  however, that
         in the  event of a Stock  Fundamental  Change  in which (A) 100% of the
         value of the consideration received by a holder of Hvide Class A Common
         Stock is common stock of the successor,  acquiror, or other third party
         (and  cash,  if any,  is  paid  only  with  respect  to any  fractional
         interests in such common stock  resulting  from such Stock  Fundamental
         Change) and (B) all Hvide Class A Common Stock will have been exchanged
         for,  converted  into,  or  acquired  for  common  stock (and cash with
         respect to fractional  interests) of the successor,  acquiror, or other
         third party, the conversion price of the Preferred Securities in effect
         immediately  prior to such  Stock  Fundamental  Change as  adjusted  by
         multiplying  such conversion price by a fraction of which the numerator
         will be one and the denominator  will be the number of shares of common
         stock of the  successor,  acquiror,  or other third party received by a
         holder of one share of Hvide  Class A Common  Stock as a result of such
         Stock Fundamental Change.

         In the absence of the Fundamental Change  provisions,  in the case of a
Transaction   each  Preferred   Security  would  become   convertible  into  the
securities,  cash, or property receivable by a holder of the number of shares of
Hvide Class A Common Stock into which such  Preferred  Security was  convertible
immediately prior to such Transaction. A failure to apply the Fundamental Change
conversion  price  adjustments  described  above could  substantially  lessen or
eliminate the value of the conversion  privilege  associated  with the Preferred
Securities. For example, if Hvide were acquired in a cash merger, each Preferred
Security  would  become  convertible  solely  into  cash and  would no longer be
convertible  into  securities  whose  value would vary  depending  on the future
prospects of Hvide and other factors.

         The foregoing  conversion  price  adjustments are designed,  in certain
circumstances,  to reduce the  conversion  price that would be  applicable  in a
Fundamental Change where all or substantially all the Hvide Class A Common Stock
is converted  into  securities,  cash,  or property and not more than 50% of the
value  received by the holders of Hvide Class A Common  Stock  consists of stock
listed or  admitted  for  listing  subject to notice of  issuance  on a national
securities  exchange or quoted on the Nasdaq  National  Market.  Such  reduction
would result in an increase in the amount of the  securities,  cash, or property
into which each  Preferred  Security is  convertible  over that which would have
been obtained in the absence of such conversion price adjustments.

         In a Non-Stock  Fundamental Change where the initial value received per
share of Hvide Class A Common Stock  (measured as described in the definition of
Applicable  Price)  is  lower  than the then  applicable  conversion  price of a
Preferred  Security but greater than or equal to the Reference Market Price, the
conversion  price will be adjusted as described  above with the effect that each
Preferred Security will be convertible into securities,  cash or property of the
same  type  received  by the  holders  of  Hvide  Class A  Common  Stock  in the
Transaction but in an amount per Preferred Security that would at the time

                                                        32

of the  Transaction  have had a value  equal to the then  applicable  redemption
price per Preferred Security set forth under "--Optional Redemption."

         In a Non-Stock  Fundamental Change where the initial value received per
share of Hvide Class A Common Stock  (measured as described in the definition of
Applicable  Price)  is lower  than  both  the  conversion  price of a  Preferred
Security in effect prior to any  adjustment  described  above and the  Reference
Market  Price,  the  conversion  price will be adjusted as  described  above but
calculated as though such initial value had been the Reference Market Price.

         In a Stock Fundamental  Change, the foregoing  adjustments are designed
to provide in effect  that (a) where  Hvide  Class A Common  Stock is  converted
partly  into such  common  stock and partly  into  other  securities,  cash,  or
property,  each Preferred  Security will be convertible  solely into a number of
shares of such common stock  determined so that the initial value of such shares
(measured as described in the  definition  of Purchaser  Stock Price) equals the
value of the shares of Hvide  Class A Common  Stock  into  which such  Preferred
Security  was  convertible  immediately  before  the  Transaction  (measured  as
aforesaid) and (b) where the Hvide Class A Common Stock is converted solely into
such common stock,  each Preferred  Security will be  convertible  into the same
number of shares of such common  stock  receivable  by a holder of the number of
shares of Hvide  Class A Common  Stock into which such  Preferred  Security  was
convertible immediately before such Transaction.

         The  term  "Applicable  Price"  means  (i) in the  case of a  Non-Stock
Fundamental  Change  in which the  holders  of the  Hvide  Class A Common  Stock
receive  only cash,  the amount of cash  received  by the holder of one share of
Hvide  Class A  Common  Stock  and  (ii) in the  event  of any  other  Non-Stock
Fundamental  Change or any Stock Fundamental  Change, the average of the Closing
Prices (as defined  herein) for the Hvide  Class A Common  Stock  during the ten
trading days prior to the record date for  determination of the holders of Hvide
Class A Common  Stock  entitled  to  receive  such  securities,  cash,  or other
property  in  connection  with  such  Non-Stock   Fundamental  Change  or  Stock
Fundamental  Change or, if there is no such record date, the date upon which the
holders of the Hvide Class A Common  Stock shall have the right to receive  such
securities, cash, or other property (such record date or distribution date being
hereinafter  referred to as the "Entitlement Date"), in each case as adjusted in
good faith by Hvide to  appropriately  reflect any of the events  referred to in
clauses  (i)  through  (vi) of the first  paragraph  under  "--Conversion  Price
Adjustments--General."

         The term "Closing  Price" means on any day the reported last sale price
on such day or in case no sale  takes  place on such  day,  the  average  of the
reported  closing bid and asked prices in each case on the Nasdaq  Composite or,
if the stock is not  traded on the  Nasdaq  National  Market,  on the  principal
national  securities  exchange or quotation system on which such stock is listed
or admitted to trading or, if not listed or admitted to trading on any  national
securities  exchange  or  quotation  system,  the average of the closing bid and
asked prices as furnished  by any NASD member  firm,  selected by the  Indenture
Trustee for that purpose.

         The term  "Current  Market Price" of Hvide Class A Common Stock for any
day means the last reported sale price,  regular way, on such day, or if no sale
takes  place on such day,  the  average of the  reported  closing  bid and asked
prices on such day,  regular  way,  in either  case as  reported  on The  Nasdaq
National  Market,  or, if the Hvide  Class A Common  Stock is not  quoted on The
Nasdaq  National  Market  on such  day,  on the  principal  national  securities
exchange or  quotation  system on which the Hvide Class A Common Stock is listed
or admitted  to  trading,  or, if not listed or admitted to trading or quoted on
any

                                                        33

national  securities  exchange or quotation system,  the average closing bid and
asked prices of the Hvide Class A Common Stock in the over-the-counter market on
the day in question as reported by the National  Quotation Bureau  Incorporated,
or a similar generally accepted reporting service,  or, if not so available,  in
such manner,  as furnished by the NASD member firm selected from time to time by
the Board of Directors of Hvide for that purpose or, if not so available in such
manner,  as  otherwise  determined  in good faith by the Board of  Directors  of
Hvide.

         The term  "Fundamental  Change" means the occurrence of any Transaction
or event in connection with a plan pursuant to which all or substantially all of
the Hvide Class A Common Stock shall be exchanged for, converted into,  acquired
for,  or  constitute  solely the right to  receive  securities,  cash,  or other
property  (whether by means of an exchange  offer,  liquidation,  tender  offer,
consolidation,    merger,    continuance,     combination,     reclassification,
recapitalization, or otherwise), provided, that, in the case of a plan involving
more than one such  Transaction  or event,  for  purposes of  adjustment  on the
conversion price, such Fundamental  Change shall be deemed to have occurred when
substantially  all of the Hvide  Class A Common  Stock shall be  exchanged  for,
converted  into,  or  acquired  for or  constitute  solely  the right to receive
securities,  cash, or other property, but the adjustment shall be based upon the
consideration  that a holder  of Hvide  Class A Common  Stock  received  in such
Transaction  or event as a result of which  more  than 50% of the Hvide  Class A
Common Stock shall have been exchanged for,  converted  into, or acquired for or
constitute solely the right to receive securities, cash, or other property.

         The term "Non-Stock  Fundamental  Change" means any Fundamental  Change
other than a Stock Fundamental Change.

         The term  "Purchaser  Stock  Price"  means,  with  respect to any Stock
Fundamental  Change,  the  average of the  Closing  Prices for the common  stock
received in such Stock Fundamental  Change for the ten consecutive  trading days
prior to and including the Entitlement  Date, as adjusted in good faith by Hvide
to  appropriately  reflect any of the events  referred to in clauses (i) through
(vi) of the first paragraph under "--Conversion Price Adjustments--General."

         The term "Reference Market Price" shall initially mean $15.08 (which is
an amount  equal to 662/3% of the last  reported  sale  price for Hvide  Class A
Common Stock on The Nasdaq National Market on June 23, 1997) and in the event of
any  adjustment  of the  conversion  price other than as a result of a Non-Stock
Fundamental  Change,  the Reference  Market Price shall also be adjusted so that
the ratio of the  Reference  Market Price to the  conversion  price after giving
effect  to any such  adjustment  shall  always  be the same as the  ratio of the
initial Reference Market Price to the initial  conversion price of the Preferred
Securities.

         The term "Stock  Fundamental  Change" means any  Fundamental  Change in
which  more than 50% of the value (as  determined  in good faith by the Board of
Directors  of Hvide) of the  consideration  received by holders of Hvide Class A
Common  Stock  consists  of common  stock  that for each of the ten  consecutive
trading  days prior to the  Entitlement  Date has been  admitted  for listing or
admitted  for listing  subject to notice of  issuance  on a national  securities
exchange  or  quoted  on  The  Nasdaq  National  Market;  provided,  however,  a
Fundamental  Change shall not be a Stock Fundamental  Change if either (i) Hvide
continues  to exist  after the  occurrence  of such  Fundamental  Change and the
outstanding  Preferred  Securities  continue to exist as  outstanding  Preferred
Securities or (ii) not later than the occurrence of such Fundamental Change, the
outstanding  Preferred  Securities are converted into or exchanged for shares of
convertible  preferred stock of an entity succeeding to the business of Hvide or
a subsidiary thereof, which

                                                        34

<PAGE>



convertible   preferred   stock   has   powers,   preferences,   and   relative,
participating,  optional, or other rights, and qualifications,  limitations, and
restrictions, substantially similar to those of the Preferred Securities.

Special Event Exchange or Redemption

         At any time  following the  occurrence  and the  continuation  of a Tax
Event or an  Investment  Company  Event  (each as  defined  herein),  the Issuer
Trustees shall direct the Conversion Agent to exchange all outstanding Preferred
Securities for Debentures and to dissolve the Trust,  provided that, in the case
of a Tax Event,  Hvide shall have the right to (a) direct that less than all, or
none,  of the  Preferred  Securities be so exchanged if and for so long as Hvide
shall have elected to pay any Additional Sums such that the net amounts received
by  the  holders  of  Preferred  Securities  not  so  exchanged  in  respect  of
Distributions  and other  distributions  are not reduced as a result of such Tax
Event,  and  shall not have  revoked  any such  election  or failed to make such
payments or (b) redeem the Preferred Securities in the manner set forth below.

         If a Tax Event  shall  occur or be  continuing,  Hvide  shall  have the
right,  upon not less  than 30 nor more  than 60 days'  notice,  to  redeem  the
Debentures,  in  whole  or in  part,  for  cash  upon  the  later of (i) 90 days
following  the  occurrence  of such Tax  Event or (ii)  July 2,  2000.  Promptly
following such redemption,  Preferred  Securities and Common  Securities with an
aggregate  liquidation  amount equal to the  aggregate  principal  amount of the
Debentures so redeemed will be redeemed by the Issuer at the liquidation  amount
thereof plus accrued and unpaid Distributions  thereon to the redemption date on
a pro rata  basis.  The Common  Securities  will be redeemed on a pro rata basis
with the Preferred Securities, except that if a Declaration Event of Default has
occurred and is continuing,  the Preferred  Securities will have a priority over
the Common Securities with respect to the Redemption Price.

         A "Special  Event" means a Tax Event or an Investment  Company Event. A
"Tax Event"  means the receipt by the  Trustee,  on behalf of the Issuer,  of an
opinion of counsel,  rendered by a law firm having a national tax and securities
practice  (which opinion shall not have been rescinded by such law firm), to the
effect that, as a result of any amendment to, or change (including any announced
prospective  change) in, the laws (or any regulations  thereunder) of the United
States or any  political  subdivision  or taxing  authority  thereof  or therein
affecting taxation, or as a result of any official administrative  pronouncement
or judicial  decision  interpreting or applying such laws or regulations,  which
amendment or change is effective or such  pronouncement or decision is announced
on or  after  the date of this  Registration  Statement,  there is more  than an
insubstantial risk in each case after the date hereof that (i) the Issuer is, or
will be within 90 days of the date  thereof,  subject to United  States  federal
income tax with respect to income  received or accrued on the  Debentures,  (ii)
interest  payable by Hvide on such  Debentures  is not, or within 90 days of the
date thereof will not be,  deductible by Hvide,  in whole or in part, for United
States federal income tax purposes; or (iii) the Issuer is, or will be within 90
days of the date  thereof,  subject  to more than a de  minimis  amount of other
taxes,  duties or other governmental  charges.  "Investment Company Event" means
the receipt by the Trustee,  on behalf of the Issuer,  of an opinion of counsel,
rendered by a law firm having a recognized  national tax and securities practice
(which  opinion shall not have been  rescinded by such law firm),  to the effect
that, as a result of the occurrence of a change in law or regulation or a change
in  interpretation  or application of law or regulation by any legislative body,
court, governmental agency or regulatory authority (a "Change in 1940 Act Law"),
that  there is more than an  insubstantial  risk  that the  Issuer is or will be
considered an "investment  company" that is required to be registered  under the
Investment Company Act of 1940, as amended (the "Investment

                                                        35

Company  Act"),  which Change in 1940 Act Law becomes  effective on or after the
date of this Registration Statement.

         "Additional Sums" means the additional  amounts (which shall constitute
part of the  Distributions)  as may be  necessary  in order  that the  amount of
Distributions  then due and payable by the Issuer on the  outstanding  Preferred
Securities and Common  Securities of the Issuer shall not be reduced as a result
of any  additional  taxes,  duties and other  governmental  charges to which the
Issuer has become subject as a result of a Tax Event.

         Holders  of  Preferred   Securities,   by  purchasing   such  Preferred
Securities,  will be  deemed  to have  agreed  to be  bound  by  these  exchange
provisions in regard to the exchange of such Preferred Securities for Debentures
on the terms  described  above.  See "Risk  Factors--Special  Event  Exchange or
Redemption."

Distribution of Debentures

         At any time,  Hvide will have the right to  dissolve  the  Issuer  and,
after  satisfaction of the liabilities of creditors of the Issuer as provided by
applicable  law,  cause the  Debentures to be  distributed to the holders of the
Preferred  Securities in liquidation of the Issuer. There can be no assurance as
to the  market  price  for the  Debentures  distributed  to the  holders  of the
Preferred  Securities  after such a  termination  of the Issuer.  Under  current
United  States  federal  income tax law and  interpretations  and  assuming,  as
expected,  the Issuer is  treated  as a grantor  trust,  a  distribution  of the
Debentures  should  not be a taxable  event to the  Issuer  and  holders  of the
Preferred  Securities.  Should  there be a  change  in law,  a  change  in legal
interpretation,   a  Special  Event  or  other   circumstances,   however,   the
distribution  could be a taxable event to holders of the  Preferred  Securities.
See "Certain Federal Income Tax Consequences--Redemption of Preferred Securities
for Debentures or Cash Upon Liquidation of the Issuer."

         After the liquidation date fixed for any distribution of Debentures for
Preferred  Securities (i) such Preferred  Securities will no longer be deemed to
be outstanding,  (ii) DTC or its nominee, as the record holder of such Preferred
Securities,  will  receive  a  registered  Global  Certificate  or  certificates
representing the Debentures to be delivered upon such distribution and (iii) any
certificates  representing  such  Preferred  Securities  not  held by DTC or its
nominee will be deemed to represent  the  Debentures  having a principal  amount
equal to the  liquidation  amount  of such  Preferred  Securities,  and  bearing
accrued  and  unpaid  interest  in an amount  equal to the  accrued  and  unpaid
Distributions on such Preferred Securities until such certificates are presented
to the Trustee for transfer or reissuance.

Optional Redemption

         Except as provided under "--Mandatory  Redemption" below, the Preferred
Securities may not be redeemed by the Issuer prior to July 2, 2000.

         On and after  such  date,  upon any  permitted  redemption  by Hvide of
Debentures,  the Preferred Securities are subject to redemption,  in whole or in
part, at the following  percentages of the liquidation  preference  thereof plus
accrued and unpaid  Distributions,  if any, to the date fixed for  redemption if
redeemed  during  the  twelve-month  period  commencing  July  2, in each of the
following years indicated:

</TABLE>

         The Issuer may not redeem the  Preferred  Securities in part unless all
accumulated and unpaid  Distributions  have been paid in full on all outstanding
Preferred Securities. If fewer than all the outstanding Preferred Securities are
to be redeemed,  the Preferred  Securities to be so redeemed will be selected as
described under "--Certain Book-Entry  Procedures" and "--Redemption  Procedures
for Global Certificates."

         In the event Hvide redeems the Debentures in certain circumstances upon
the occurrence of a Tax Event as described  under  "--Special  Event Exchange or
Redemption," the appropriate amount of the Preferred Securities will be redeemed
at 100% of the principal  amount thereof  together with  accumulated  and unpaid
Distributions to the redemption date.

         If at any time following the Conversion  Expiration  Date, less than 5%
of the Preferred  Securities offered hereby remain  outstanding,  such Preferred
Securities shall be redeemable at the option of the Issuer,  in whole but not in
part, at a redemption price of $50 per Preferred  Security,  and all accumulated
and unpaid Distributions.

Mandatory Redemption

         Upon  repayment at maturity or as a result of the  acceleration  of the
Debentures upon the occurrence of a "Debenture Event of Default" described under
"Description  of the  Debentures--Debenture  Events of Default," the  Debentures
shall be subject to mandatory  redemption,  in whole but not in part,  by Hvide,
and the  proceeds  from such  repayment  will be  applied  to  redeem  Preferred
Securities and Common Securities having an aggregate liquidation amount equal to
the  aggregate  principal  amount  of  Debentures  so repaid  or  redeemed  at a
redemption  price equal to the  respective  liquidation  amount of the Preferred
Securities  and  Common  Securities  or,  in the  case  of a  redemption  of the
Debentures,  at the  redemption  price paid with respect to the  Debentures,  as
described  below,  together with  accumulated  and unpaid  Distributions  on the
Preferred  Securities and Common  Securities to the date of  redemption.  In the
case  of  acceleration  of the  Debentures,  the  Preferred  Securities  will be
redeemed only when repayment of the Debentures has actually been received by the
Issuer.  In addition,  as described  above under  "--Special  Event  Exchange or
Redemption," upon the occurrence of a Special Event,  Preferred Securities shall
be exchanged for Debentures unless, in the case of a Tax Event, Hvide shall have
elected  to  (a)  pay  any  Additional   Sums  such  that  the  net  amounts  of
Distributions  received  by the  holders  of  any  Preferred  Securities  not so
exchanged  are not  reduced  as a result  of such Tax  Event  and shall not have
revoked  any such  election  or failed to make such  payments  or (b) redeem the
Preferred  Securities  as further  set forth in  "--Special  Event  Exchange  or
Redemption."

Redemption Procedures

         Preferred Securities redeemed on the date fixed for redemption shall be
redeemed  at  the  redemption  price  with  the  applicable  proceeds  from  the
contemporaneous redemption of the Debentures.

                                                        37

<PAGE>



Redemptions of the Preferred  Securities  shall be made and the redemption price
shall be payable on the  redemption  date only to the extent that the Issuer has
funds on hand  available  for the  payment of such  redemption  price.  See also
"--Subordination of Common Securities."

         Notice  of  any   redemption   (optional  or  mandatory)  of  Preferred
Securities  (which notice will be  irrevocable)  will be given by the Trustee to
each recordholder of Preferred Securities that are being redeemed not fewer than
30 nor more than 60 days prior to the  redemption  date.  If the Trustee gives a
notice of  redemption  in respect of the  Preferred  Securities,  then, by 12:00
noon,  New York City time,  on the  redemption  date,  to the  extent  funds are
available,  the Trustee  will  deposit  irrevocably  with DTC or the  Conversion
Agent,  as the case may be, funds  sufficient to pay the  applicable  redemption
price and will give DTC or the Conversion Agent, as the case may be, irrevocable
instructions  and authority to pay the  redemption  price to the holders of such
Preferred   Securities.   See  "--Certain   Book-Entry   Procedures  for  Global
Certificates."  If such Preferred  Securities are no longer in book-entry  form,
the Trustee,  to the extent funds are available,  will irrevocably  deposit with
the Paying Agent funds  sufficient to pay the  applicable  redemption  price and
will give the Paying Agent  irrevocable  instructions  and  authority to pay the
redemption  price to the holders  thereof upon  surrender of their  certificates
evidencing   such   Preferred   Securities.   Notwithstanding   the   foregoing,
Distributions  payable  on or prior  to the  redemption  date for any  Preferred
Securities  called  for  redemption  shall be  payable  to the  holders  of such
Preferred   Securities  as  of  the  relevant   record  dates  for  the  related
distribution  dates.  If notice of  redemption  shall  have been given and funds
deposited as  required,  then upon the date of such  deposit,  all rights of the
holders  of such  Preferred  Securities  so called  for  redemption  will  cease
(including  the  accumulation  of  Distributions  and  conversion  rights of the
Preferred  Securities),  except  the  right  of the  holders  of such  Preferred
Securities  to receive  the  redemption  price,  but  without  interest  on such
redemption price, and such Preferred Securities will cease to be outstanding. In
the event that any date fixed for  redemption  of Preferred  Securities is not a
Business Day, then payment of the redemption  price on such date will be made on
the next  succeeding  day which is a Business  Day (and  without any interest or
other  payment in respect of any such delay),  except that, if such Business Day
falls in the next calendar  year,  such payment will be made on the  immediately
preceding  Business  Day. In the event that payment of the  redemption  price in
respect of Preferred  Securities called for redemption is improperly withheld or
refused and not paid either by the Issuer or by Hvide  pursuant to the Guarantee
as  described  under  "Description  of the  Guarantee,"  distributions  on  such
Preferred  Securities will continue to accumulate at the then  applicable  rate,
from the redemption date  originally  established by the Issuer to the date such
redemption price is actually paid, in which case the actual payment date will be
the date fixed for redemption for purposes of calculating the redemption price.

         Subject to applicable law (including, without limitation, United States
federal  securities law), Hvide, or its  subsidiaries,  may at any time and from
time to time purchase  outstanding  Preferred  Securities by tender, in the open
market or by private agreement.

         Payment of the  redemption  price on the Preferred  Securities  and any
distribution or exchange of Debentures to holders of Preferred  Securities shall
be made to the applicable  recordholders  thereof as they appear on the register
for such Preferred  Securities on the relevant  record date,  which shall be the
fifteenth  day (whether or not a Business Day) prior to the  redemption  date or
liquidation date, as applicable.

         If less than all of the Preferred  Securities and Common Securities are
to be redeemed on a redemption  date, then the aggregate  liquidation  amount of
such  Preferred  Securities  and  Common  Securities  to be  redeemed  shall  be
allocated pro rata among the Preferred Securities and the Common Securities. The
particular  Preferred  Securities to be redeemed shall be selected not more than
60 days  prior  to the  redemption  date by the  Trustee  from  the  outstanding
Preferred  Securities not previously  called for  redemption,  by lot or by such
method as the Trustee shall deem fair and  appropriate and which may provide for
the selection for redemption of portions  (equal to $50 or an integral  multiple
of $50 in excess thereof) of the liquidation amount of the Preferred Securities.
The  Trustee  shall  promptly  notify  the  Conversion  Agent in  writing of the
Preferred  Securities  selected for redemption and, in the case of any Preferred
Securities selected for partial redemption, the liquidation amount thereof to be
redeemed;  it being understood that, in the case of Preferred Securities held by
DTC (or any successor) or its nominee,  the distribution of the proceeds of such
redemption will be made in accordance with the procedures of DTC or its nominee.
For all purposes of the Trust Agreement,  unless the context otherwise requires,
all provisions relating to the redemption of Preferred  Securities shall relate,
in the case of any Preferred Securities redeemed or to be redeemed only in part,
to the portion of the aggregate liquidation amount of Preferred Securities which
has been or is to be redeemed.

         Notice of any redemption of Debentures  will be mailed at least 30 days
but  not  more  than 60 days  before  the  redemption  date  to each  holder  of
Debentures to be redeemed at its  registered  address.  Unless Hvide defaults in
payment of the  redemption  price,  on and after the redemption  date,  interest
ceases to accrue on such Debentures or portions thereof called for redemption.

Subordination of Common Securities

         Payment of Distributions on, and the redemption price of, the Preferred
Securities and Common Securities, as applicable, shall be made pro rata based on
the  liquidation  amount of such  Preferred  Securities  and Common  Securities;
provided,  however,  that if on any  distribution  date or  redemption  date,  a
Declaration  Event of Default shall have occurred and be continuing,  no payment
of any Distribution  on, or redemption  price of, any of the Common  Securities,
and no  other  payment  on  account  of the  redemption,  liquidation  or  other
acquisition of such Common  Securities,  shall be made unless payment in full in
cash of all  accumulated  and  unpaid  Distributions  on all of the  outstanding
Preferred  Securities  for all  Distribution  periods  terminating  on or  prior
thereto,  or in the case of payment of the  redemption  price the full amount of
such redemption price on all of the outstanding Preferred Securities then called
for redemption, shall have been made or provided for, and all funds available to
the  Trustee  shall  first  be  applied  to the  payment  in full in cash of all
Distributions on, or redemption price of, the Preferred  Securities then due and
payable.

Liquidation Distribution upon Dissolution

         In the event of any voluntary or involuntary  dissolution of the Issuer
(each, a  "Liquidation"),  the holders of the Preferred  Securities at that time
will be entitled to receive out of the assets of the Issuer,  after satisfaction
of  liabilities  to  creditors  of the Issuer as  provided  by  applicable  law,
distributions  in an amount  equal to the  aggregate  of the stated  liquidation
amount of $50 per Preferred  Security plus accumulated and unpaid  Distributions
thereon to the date of payment  (the  "Liquidation  Distribution"),  unless,  in
connection with such Liquidation, after satisfaction of liabilities to creditors
of the  Issuer  as  provided  by  applicable  law,  Debentures  in an  aggregate
principal  amount equal to the aggregate stated  liquidation  amount of, with an
interest rate identical to the distribution rate of, and accrued and unpaid

                                                        39

<PAGE>



interest equal to accumulated and unpaid Distributions on, the Preferred 
Securities, have been distributed on a pro rata basis to the holders of 
Preferred Securities in exchange for such Preferred Securities.  See
"--Distribution of Debentures."

         If such  Liquidation  Distribution can be paid only in part because the
Issuer  has  insufficient   assets  available  to  pay  in  full  the  aggregate
Liquidation Distribution, then the amounts payable directly by the Issuer on the
Preferred  Securities shall be paid on a pro rata basis.  Hvide will be entitled
to receive Liquidation Distributions upon any such liquidation pro rata with the
holders of the Preferred Securities, except that if a Debenture Event of Default
has occurred and is continuing,  the Preferred  Securities shall have a priority
over the Common Securities.

         Pursuant to the Declaration,  the Issuer shall  automatically  dissolve
upon  expiration  of its term and shall  dissolve  on the first to occur of: (i)
certain  events of bankruptcy,  dissolution  or liquidation of Hvide;  (ii) upon
receipt by the  Trustee  of  written  direction  from  Hvide,  as sponsor of the
Issuer,  to dissolve the Issuer  (which  direction is optional and wholly within
the discretion of Hvide,  as depositor);  (iii) the redemption,  conversion,  or
exchange of all of the  Preferred  Securities  and Common  Securities;  (iv) the
entry by a court of competent  jurisdiction  of an order for the  dissolution of
the Issuer;  (v) the  occurrence  of a Special Event except in the case of a Tax
Event following which Hvide has elected to pay any Additional Sums such that the
net  amount   received  by  holders  of  Preferred   Securities  in  respect  of
Distributions  is not  reduced  as a result  of such Tax Event and Hvide has not
revoked any such election or failed to make such payment;  and (vi) distribution
of all of the underlying  Hvide Class A Common Stock to all holders of Preferred
Securities upon conversion of all of the Preferred Securities.

Declaration Events of Default; Notice

         An  event  of  default  under  the  Indenture  (a  "Debenture  Event of
Default")  constitutes an event of default under the Declaration with respect to
the Preferred  Securities  and the Common  Securities (a  "Declaration  Event of
Default"),  whatever the reason for such Debenture  Event of Default and whether
it shall be  voluntary  or  involuntary  or be effected by  operation  of law or
pursuant  to any  judgment,  decree or order of any court or any order,  rule or
regulation of any administrative or governmental body.

         Within  ten days  after  the  occurrence  of any  Declaration  Event of
Default actually known to the Trustee, the Trustee shall transmit notice of such
Declaration  Event of Default to the holders of the  Preferred  Securities,  the
Company  Trustees and Hvide,  as  depositor,  unless such  Declaration  Event of
Default shall have been cured or waived.  Hvide,  as depositor,  and the Company
Trustees,  on behalf of the  Issuer,  are  required  to file  annually  with the
Trustee a certificate  as to whether or not they are in compliance  with all the
conditions and covenants applicable to them under the Declaration.

         If a Declaration  Event of Default has occurred and is continuing,  the
Preferred  Securities  shall have a preference  over the Common  Securities upon
dissolution of the Issuer as described  above. See  "--Liquidation  Distribution
Upon  Dissolution."  The  existence of a  Declaration  Event of Default does not
entitle the holders of Preferred Securities to accelerate the maturity thereof.

         In the case of any  Declaration  Events of Default,  Hvide as holder of
the  Common  Securities  will be  deemed  to have  waived  any right to act with
respect to any such Declaration  Events of Default until such Declaration Events
of Default with respect to the Preferred  Securities have been cured,  waived or
otherwise eliminated.  Until any such Declaration Events of Default with respect
to the Preferred

                                                        40

<PAGE>



Securities have been so cured, waived or otherwise eliminated, the Trustee shall
act  solely on behalf of the  holders  of the  Preferred  Securities  and not on
behalf of Hvide as holder of the Common Securities,  and only the holders of the
Preferred  Securities  will have the right to direct the Trustee to act on their
behalf.

Enforcement of Certain Rights by Holders of Preferred Securities

         If a Declaration  Event of Default has occurred and is continuing,  the
Trustee,  as the sole holder of the  Debentures,  shall have the right under the
Indenture to declare the principal of,  premium,  if any, on and interest on the
Debentures  immediately  due and  payable,  and,  accordingly,  the  holders  of
Preferred  Securities would rely on the enforcement by the Trustee of its rights
as a holder of the  Debentures  against  Hvide.  In  addition,  the holders of a
majority in aggregate  liquidation amount of the Preferred  Securities will have
the right to direct the time,  method and place of conducting any proceeding for
any remedy  available  to the Trustee or to direct the  exercise of any trust or
power conferred upon the Trustee under the  Declaration,  including the right to
direct the Trustee to exercise the  remedies  available to it as a holder of the
Debentures.  If the  Trustee  fails to  enforce  its  rights  as  holder  of the
Debentures  after a request therefor by a holder of Preferred  Securities,  such
holder  may   proceed  to  enforce   such   rights   directly   against   Hvide.
Notwithstanding  the foregoing,  if a Declaration  Event of Default has occurred
and is continuing and such event is  attributable to the failure of Hvide to pay
interest or principal on the  Debentures  on the date such interest or principal
is otherwise  payable (or in the case of redemption,  on the  redemption  date),
then a holder of Preferred  Securities  may directly  institute a Direct  Action
against Hvide for  enforcement  of payment to such holder of the principal of or
interest on the  Debentures  having a principal  amount  equal to the  aggregate
liquidation  amount of the  Preferred  Securities of such holder on or after the
respective due date specified in the Debentures.  In connection with such Direct
Action,  Hvide  will be  subrogated  to the rights of such  holder of  Preferred
Securities  under the  Declaration to the extent of any payment made by Hvide to
such  holder of  Preferred  Securities  in such  Direct  Action.  The holders of
Preferred  Securities  will not be able to exercise  directly  against Hvide any
other remedy available to the Trustee unless the Trustee first fails to do so.

Merger or Consolidation of Issuer Trustees

         Any  corporation  into which the Trustee,  the Delaware  Trustee or any
Company  Trustee that is not a natural person may be merged or converted or with
which it may be  consolidated,  or any  corporation  resulting  from any merger,
conversion or  consolidation  to which such Issuer Trustee shall be a party,  or
any  corporation  succeeding to all or  substantially  all the  corporate  trust
business of such Issuer  Trustee,  shall be the Successor of such Issuer Trustee
under the Declaration,  provided such corporation  shall be otherwise  qualified
and eligible.

Mergers, Consolidations, Amalgamations or Replacements of the Issuer

         The Issuer may not merge with or into, consolidate,  amalgamate,  or be
replaced  by,  or  convey,   transfer  or  lease  its   properties   and  assets
substantially  as an  entirety to any  corporation  or other  person,  except as
described  below.  The Issuer may, at the request of Hvide,  with the consent of
the  Company  Trustees  and without the  consent of the  Trustee,  the  Delaware
Trustee  or the  holders  of the  Preferred  Securities,  merge  with  or  into,
consolidate,  amalgamate,  be  replaced  by or  convey,  transfer  or lease  its
properties and assets  substantially as an entirety to a trust organized as such
under the laws of any state,  provided that (i) such successor entity either (a)
expressly assumes all of the obligations of the Issuer with

                                                        41

<PAGE>



respect  to the  Preferred  Securities  or (b)  substitutes  for  the  Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities") so long as the Successor Securities rank
the  same  as  the  Preferred  Securities  rank  in  priority  with  respect  to
Distributions  and payments upon  liquidation,  redemption and  otherwise,  (ii)
Hvide expressly  appoints a trustee of such successor entity possessing the same
powers and duties as the  Trustee  as the  holder of the  Debentures,  (iii) the
Successor Securities are listed, or any Successor Securities will be listed upon
notification  of  issuance,   on  any  national  securities  exchange  or  other
organization  on which the Preferred  Securities  are then listed,  if any, (iv)
such merger, consolidation,  amalgamation,  replacement, conveyance, transfer or
lease  does  not  cause  the  Preferred  Securities   (including  any  Successor
Securities) to be downgraded by any  nationally  recognized  statistical  rating
organization,  (v)  such  merger,  consolidation,   amalgamation,   replacement,
conveyance,  transfer or lease does not adversely affect the rights, preferences
and  privileges  of the  holders  of the  Preferred  Securities  (including  any
Successor  Securities)  in any material  respect (other than with respect to any
dilution of the holders' interest in the new entity), (vi) such successor entity
has a purpose  identical  to that of the  Issuer,  (vii)  prior to such  merger,
consolidation,  amalgamation,  replacement, conveyance, transfer or lease, Hvide
has received an opinion from  independent  counsel to the Issuer  experienced in
such  matters to the effect that (a) such merger,  consolidation,  amalgamation,
replacement, conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Preferred Securities (including
any Successor  Securities)  in any material  respect (other than with respect to
any dilution of the holders'  interest in the new entity) and (b) following such
merger, consolidation, amalgamation, replacement, conveyance, transfer or lease,
neither the Issuer nor such successor  entity will be required to register as an
investment  company  under the  Investment  Company Act, and (viii) Hvide or any
permitted  successor  or  assignee  owns all of the  Common  Securities  of such
successor  entity and guarantees the obligations of such successor  entity under
the  Successor  Securities  at least to the extent  provided  by the  Guarantee.
Notwithstanding the foregoing,  the Issuer shall not, except with the consent of
holders of 100% in aggregate  liquidation  amount of the  Preferred  Securities,
consolidate,  amalgamate, merge with or into, be replaced by or convey, transfer
or lease its  properties  and assets  substantially  as an entirety to any other
entity or permit  any other  entity to  consolidate,  amalgamate,  merge with or
into, or replace it if such consolidation,  amalgamation,  merger,  replacement,
conveyance,  transfer or lease would cause the Issuer or the successor entity to
be classified as other than a grantor trust for United States federal income tax
purposes.

Voting Rights; Amendment of the Declaration

         Except   as   provided   below   and   under    "Description   of   the
Guarantee--Amendments  and Assignment" and as otherwise  required by law and the
Declaration, the holders of the Preferred Securities will have no voting rights.

         The  Declaration  may be  amended  from  time to time by Hvide  and the
Issuer Trustees,  without the consent of the holders of the Preferred Securities
(i)  to  cure  any  ambiguity,  correct  or  supplement  any  provisions  in the
Declaration that may be inconsistent  with any other  provision,  or to make any
other  provisions  with  respect  to  matters  or  questions  arising  under the
Declaration  that shall not be  inconsistent  with the other  provisions  of the
Declaration,  (ii)  to  modify,  eliminate  or  add  to  any  provision  of  the
Declaration  to such extent as shall be necessary to ensure that the Issuer will
be classified  for United States  federal income tax purposes as a grantor trust
at all times that any Preferred Securities and Common Securities are outstanding
or to ensure that the Issuer will not be required to register as an  "investment
company"  under the  Investment  Company  Act or be  classified  as other than a
grantor trust

                                                        42

<PAGE>



for United  States  federal  income tax purposes or (iii) to qualify or maintain
the  qualification of the Declaration  under the Trust Indenture Act;  provided,
however,  that in the case of clause (i), such action shall not adversely affect
in any material  respect the interests of any holder of Preferred  Securities or
Common Securities,  and any amendments of the Declaration shall become effective
when notice  thereof is given to the holders of Preferred  Securities and Common
Securities. The Declaration may be amended by the Issuer Trustees and Hvide with
(i) the  consent of holders  representing  not less than a majority  (based upon
liquidation  amounts)  of  the  outstanding   Preferred  Securities  and  Common
Securities, acting as a single class, and (ii) receipt by the Issuer Trustees of
an opinion of counsel to the effect that such  amendment  or the exercise of any
power granted to the Issuer  Trustees in accordance with such amendment will not
affect the Issuer's  status as a grantor trust for United States  federal income
tax  purposes  or the  Issuer's  exemption  from the  status  of an  "investment
company" under the Investment Company Act; provided further that (a) without the
consent  of each  holder of  Preferred  Securities  and Common  Securities,  the
Declaration  may not be  amended  to (i)  change  the  amount  or  timing of any
Distribution  on the  Preferred  Securities  and Common  Securities or otherwise
adversely affect the amount of any  Distribution  required to be made in respect
of the Preferred Securities and Common Securities as of a specified date or (ii)
restrict the right of a holder of Preferred  Securities and Common Securities to
institute suit for the enforcement of any such payment on or after such date.

         If any  proposed  amendment  of the  Declaration  provides  for, or the
Issuer Trustees  otherwise  proposes to effect,  the dissolution,  winding-up or
termination of the Issuer,  other than pursuant to the terms of the Declaration,
then the holders of the then outstanding Preferred Securities,  as a class, will
be entitled to vote on such amendment or proposal and such amendment or proposal
shall not be  effective  except with the approval of the holders of the majority
in aggregate liquidation amount of the Preferred Securities.

         The holders of a majority in aggregate  liquidation amount of Preferred
Securities  will  have  the  right to  direct  the  time,  method  and  place of
conducting any  proceeding for any remedy  available to the Trustee or to direct
the  exercise  of any  trust  or power  conferred  upon the  Trustee  under  the
Declaration,  including the right to direct the Trustee to exercise the remedies
available to it as a holder of the  Debentures.  So long as any  Debentures  are
held by the Trustee,  the Issuer Trustees shall not (i) direct the time,  method
and place of conducting any proceeding for any remedy available to the Indenture
Trustee or executing any trust or power conferred on the Indenture  Trustee with
respect to such  Debentures,  (ii) waive any past default that is waivable under
Section 5.13 of the  Indenture,  (iii)  exercise any right to rescind or annul a
declaration  that the principal of all the Debentures  shall be due and payable,
or (iv) consent to any amendment,  modification  or termination of the Indenture
or the  Debentures  where such consent shall be required,  without in each case,
obtaining  the  prior  approval  of  the  holders  of a  majority  in  aggregate
liquidation amount of all outstanding  Preferred  Securities (except in the case
of clause (iv), which consent, in the event that no Declaration Event of Default
shall occur and be continuing,  shall be of the holders of Preferred  Securities
and Common Securities,  voting together as a single class);  provided,  however,
that where a consent  under the  Indenture  would  require  the  consent of each
holder of  Debentures  affected  thereby,  no such consent shall be given by the
Trustee  without  the prior  written  consent  of each  holder of the  Preferred
Securities.   The  Issuer  Trustees  shall  not  revoke  any  action  previously
authorized  or  approved by a vote of the  holders of the  Preferred  Securities
except by  subsequent  vote of the  holders  of the  Preferred  Securities.  The
Trustee  shall notify each holder of record of the  Preferred  Securities of any
notice of default with respect to the Debentures.

         A waiver of a Debenture  Event of Default  will  constitute a waiver of
the corresponding Declaration Event of Default.

         Any required  approval or direction of holders of Preferred  Securities
may be given at a separate meeting of holders of Preferred  Securities  convened
for such purpose, at a meeting of all of the holders of the Preferred Securities
and the Common Securities or pursuant to written consent. The Trustee will cause
a notice of any meeting at which holders of Preferred Securities are entitled to
vote,  or of any matter upon which action by written  consent of such holders is
to be taken, to be given to each holder of record of Preferred Securities in the
manner set forth in the Trust Agreement.

         No vote or  consent  of the  holders of  Preferred  Securities  will be
required  for the  Issuer to redeem  and  cancel  the  Preferred  Securities  in
accordance with the Declaration.

         Notwithstanding  that holders of Preferred  Securities  are entitled to
vote or  consent  under any of the  circumstances  described  above,  any of the
Preferred  Securities  that are owned at such time by Hvide,  any  affiliate  of
Hvide,  the Issuer  Trustees or any affiliate of any Issuer Trustee  shall,  for
purposes of such vote or  consent,  be treated as if such  Preferred  Securities
were not outstanding.

         The procedures by which holders of Preferred Securities may exercise 
their voting rights are described below.  See "--Certain Book-Entry Procedures 
for Global Certificates."

         Holders of the Preferred  Securities  will have no rights to appoint or
remove the Issuer Trustees, who may be appointed,  removed or replaced solely by
Hvide, as the direct or indirect holder of all the Common Securities.

Payment and Paying Agency

         Payments in respect of the Preferred  Securities  shall be made to DTC,
which shall credit the relevant  accounts at DTC on the applicable  distribution
dates or, if the Preferred  Securities  are not held by DTC, such payments shall
be made by check  mailed to the address of the holder  entitled  thereto as such
address  shall  appear  on the  Securities  Register.  The  Paying  Agent  shall
initially  be the  Trustee  and any  co-paying  agent  chosen by the Trustee and
acceptable  to the  Company  Trustees  and  Hvide.  The  Paying  Agent  shall be
permitted to resign as Paying Agent upon 30 days' written  notice to the Trustee
and Hvide. In the event that the Trustee shall no longer be the Paying Agent the
Company  Trustees  shall  appoint a  successor  (which  shall be a bank or trust
company acceptable to the Company Trustees and Hvide) to act as Paying Agent.

Certain Book-Entry Procedures for Global Certificates

         The description of book-entry  procedures in this  Prospectus  includes
summaries of certain rules and operating procedures of DTC that affect transfers
of interests in the global certificate or certificates issued in connection with
sales of Preferred  Securities made pursuant to this  Prospectus.  Substantially
all of the  Preferred  Securities  were  issued as fully  registered  securities
registered  in the name of Cede & Co. (as  nominee  for DTC).  Fully  registered
global Preferred Security certificates (the "Global  Certificates") were issued,
representing such Preferred Securities and were deposited with DTC.


                                                        44

<PAGE>



         DTC has advised the Issuer and the Company as follows: DTC is a limited
purpose  trust  company  organized  under the laws of the  State of New York,  a
member of the  Federal  Reserve  System,  a  "clearing  corporation"  within the
meaning  of the  Uniform  Commercial  Code and a  "clearing  agency"  registered
pursuant to the  provisions  of Section 17A of the Exchange Act. DTC was created
to hold  securities  for its  participants  ("participants")  and facilitate the
clearance and settlement of securities transactions between participants through
electronic   book-entry  changes  in  accounts  of  its  participants,   thereby
eliminating  the  need for  physical  transfer  and  delivery  of  certificates.
Participants include securities brokers and dealers,  banks, trust companies and
clearing  corporations  and may include  certain other  organizations.  Indirect
access to the DTC system is available to other entities such as banks,  brokers,
dealers  and  trust  companies  that  clear  through  or  maintain  a  custodial
relationship  with a  participant,  either  directly  or  indirectly  ("indirect
participants").

         DTC has advised the Issuer and the Company  that its current  practice,
upon the issuance of Global Certificates,  is to credit, on its internal system,
the  respective   principal  amount  of  the  individual   beneficial  interests
represented  by  such  Global  Certificates  to  the  accounts  with  DTC of the
participants  through  which  such  interests  are  to  be  held.  Ownership  of
beneficial  interests  in the  Global  Certificates  will be shown  on,  and the
transfer of that ownership will be effected only through,  records maintained by
DTC or its nominees (with respect to interests of participants)  and the records
of participants and indirect  participants (with respect to interests of persons
other than participants).

         As long as DTC, or its nominee,  is the  registered  holder of a Global
Certificate,  DTC or such nominee,  as the case may be, will be  considered  the
sole owner and holder of the  Preferred  Securities  represented  by such Global
Certificate for all purposes under the Declaration and the Preferred Securities.

         Except in certain limited  circumstances owners of beneficial interests
in a Global Certificate will not be entitled to have any portions of such Global
Certificate  registered  in their  names,  will not  receive or be  entitled  to
receive  physical  delivery of Preferred  Securities in definitive form and will
not be  considered  the  owners or holders  of the  Global  Certificate  (or any
Preferred Securities represented thereby) under the Declaration or the Preferred
Securities.

         Investors  may hold their  interests  in Global  Certificates  directly
through DTC, if they are  participants  in such system,  or  indirectly  through
organizations  (including  Euroclear and CEDEL),  which are participants in such
system.  All  interests in a Global  Certificate,  including  those held through
Euroclear or CEDEL,  will be subject to the procedures and  requirements of DTC.
Those  interests  held through  Euroclear  and CEDEL will also be subject to the
procedures and requirements of such system.

         The laws of some states  require  that certain  persons  take  physical
delivery in  definitive  form of  securities  that they own.  Consequently,  the
ability to transfer beneficial interests in a Global Certificate to such persons
may be limited. Because DTC can act only on behalf of its participants, which in
turn act on behalf of indirect  participants and certain banks, the ability of a
person  having  beneficial  interests  in a Global  Certificate  to pledge  such
interest to persons or entities that do not  participate  in the DTC system,  or
otherwise take actions in respect of such interests, may be affected by the lack
of a certificate evidencing such interests.

         Payments of Distributions on Global Certificates will be made to DTC or
its nominee as the registered  owner thereof.  Neither the Issuer,  the Company,
the Trustee nor any of their respective  agents will have any  responsibility or
liability for any aspect of the records relating to or payments made on

                                                        45

<PAGE>



account of  beneficial  ownership  interests in the Global  Certificates  or for
maintaining,  supervising or reviewing any records  relating to such  beneficial
ownership interests.

         The Issuer and the Company expect that DTC or its nominee, upon receipt
of any payment of Distributions in respect of a Global Certificate  representing
any Preferred  Securities  held by it or its nominee,  will  immediately  credit
participants'   accounts  with  payments  in  amounts   proportionate  to  their
respective   beneficial  interests  in  the  principal  amount  of  such  Global
Certificate for such Preferred  Securities as shown on the records of DTC or its
nominee. The Issuer and the Company also expect that payments by participants to
owners of  beneficial  interests  in such Global  Certificate  held through such
participants will be governed by standing  instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in "street name." Such payments will be the responsibility of such participants.

         Except for trades  involving  only  Euroclear  and CEDEL  participants,
interests  in the  Global  Certificates  will  trade  in  DTC's  Same-Day  Funds
Settlement  System and secondary  market trading activity in such interests will
therefore  settle in immediately  available  funds,  subject in all cases to the
rules and procedures of DTC and its participants. Transfers between participants
in DTC will be effected in accordance with DTC's procedures, and will be settled
in same day funds. Transfers between participants in Euroclear and CEDEL will be
effected in the customary  manner in accordance with their  respective rules and
operating procedures.

         Subject to  compliance  with the  transfer  and  exchange  restrictions
applicable to the Preferred Securities described elsewhere herein,  cross-market
transfers  between DTC  participants,  on the one hand,  and  Euroclear or CEDEL
participants,  on the other hand,  will be effected  by DTC in  accordance  with
DTC's  rules on  behalf  of  Euroclear  or  CEDEL,  as the  case may be,  by its
respective  depositary;  however,  such  cross-market  transactions will require
delivery  of  instructions  to  Euroclear  or CEDEL,  as the case may be, by the
counterparts  in such system in  accordance  with the rules and  procedures  and
within the established  deadlines  (Brussels time) of such system.  Euroclear or
CEDEL,  as the  case may be,  will,  if the  transaction  meets  its  settlement
requirements,  deliver instructions to its respective  depository to take action
to effect final settlement on its behalf by delivering or receiving interests in
the relevant  Global  Certificate  in DTC,  and making or  receiving  payment in
accordance with customary procedures for same-day funds settlement applicable to
DTC. Euroclear  participants and CEDEL participants may not deliver instructions
directly to the depositories for Euroclear or CEDEL.

         Because of time zone differences, the securities account of a Euroclear
or CEDEL participant  purchasing an interest in a Global  Certificate from a DTC
participant  will be credited,  and any such  crediting  will be reported to the
relevant  Euroclear  or CEDEL  participant,  during  the  securities  settlement
processing  day  (which  must  be  a  business  day  for  Euroclear  and  CEDEL)
immediately  following the DTC  settlement  date.  Cash received in Euroclear or
CEDEL as a result of sales of interests in a Global  Certificate by or through a
Euroclear or CEDEL  participant to a DTC participant will be received with value
on the DTC  settlement  date but will be available in the relevant  Euroclear or
CEDEL cash account only as of the business day for Euroclear or CEDEL  following
the DTC settlement date.

         DTC has advised the Issuer and the Company that it will take any action
permitted  to be  taken  by a  holder  of  Global  Certificates  (including  the
presentation  of Preferred  Securities  for exchange as described  below and the
conversion  of  Preferred  Securities)  only  at the  direction  of one or  more
participants to whose account with DTC interests in the Global  Certificates are
credited and only in

                                                        46

<PAGE>



respect of such portion of the  aggregate  liquidation  amount of the  Preferred
Securities as to which such  participant or participants  has or have given such
direction. However, if there is a Declaration Event of Default, DTC reserves the
right to exchange the Global  Certificates for legended Preferred  Securities in
certificated   form,  and  to  distribute  such  Preferred   Securities  to  its
participants.

         Although  DTC,  Euroclear  and  CEDEL  have  agreed  to  the  foregoing
procedures in order to facilitate transfers of beneficial ownership interests in
the Global Certificates among participants of DTC, Euroclear and CEDEL, they are
under no obligation to perform or continue to perform such procedures,  and such
procedures may be discontinued at any time. None of the Issuer, the Company, the
Trustee nor any of their respective agents will have any  responsibility for the
performance  by  DTC,  Euroclear  and  CEDEL,  their  participants  or  indirect
participants  of their  respective  obligations  under the rules and  procedures
governing their operations, including maintaining,  supervising or reviewing the
records  relating  to, or  payments  made on account  of,  beneficial  ownership
interests in Global Certificates.

         Redemption  notices shall be sent to Cede as the  registered  holder of
the Preferred Securities. If less than all of the Preferred Securities are being
redeemed,  DTC's  current  practice  is to  determine  by lot the  amount of the
interest of each direct participant to be redeemed.

         Although voting with respect to the Preferred  Securities is limited to
the holders of record of the Preferred Securities, in those instances in which a
vote is required,  neither DTC nor Cede will itself consent or vote with respect
to Preferred Securities.  Under its usual procedures,  DTC would mail an omnibus
proxy (the "Omnibus  Proxy") to the Trustee as soon as possible after the record
date.  The Omnibus  Proxy  assigns  Cede's  consenting or voting rights to those
direct participants to whose accounts such Preferred  Securities are credited on
the record date (identified in a listing attached to the Omnibus Proxy).

         Conveyance of notices and other  communications by DTC to participants,
by  participants  to indirect  participants,  and by  participants  and indirect
participants  to beneficial  owners of the Preferred  Securities  and the voting
rights of participants, indirect participants and beneficial owners of Preferred
Securities will be governed by arrangements among them, subject to any statutory
or regulatory requirements as may be in effect from time to time.

         DTC may  discontinue  providing its services as  securities  depositary
with respect to the Preferred Securities at any time by giving reasonable notice
to the Trustee and Hvide. In the event that a successor securities depositary is
not obtained,  definitive  Preferred Securities  certificates  representing such
Preferred  Securities  are required to be printed and delivered.  Hvide,  at its
option,  may decide to  discontinue  use of the system of  book-entry  transfers
through DTC (or a successor depositary). After a Debenture Event of Default, the
holders  of a  majority  in  liquidation  amount  of  Preferred  Securities  may
determine to discontinue the system of book-entry  transfers through DTC. In any
such event, definitive certificates for the Preferred Securities will be printed
and delivered.

Transfer Agent, Registrar and Paying, Conversion and Exchange Agent

         The Bank of New York, the Trustee,  currently  acts as transfer  agent,
registrar  and  paying,   conversion   and  exchange  agent  for  the  Preferred
Securities.


                                                        47

<PAGE>



         Registration of transfers or exchanges of Preferred  Securities will be
effected  without charge by or on behalf of the Issuer,  but upon payment of any
tax or other  governmental  charges that may be imposed in  connection  with any
transfer or exchange. The Issuer will not be required to register or cause to be
registered  the  transfer  of the  Preferred  Securities  after  such  Preferred
Securities have been called for redemption.

Information Concerning the Trustee

         Hvide and certain of its subsidiaries may maintain deposit accounts and
conduct other banking and corporate  securities  transactions and  relationships
with the Trustee in the ordinary course of their businesses.  The Trustee, other
than during the  occurrence and  continuance of a Declaration  Event of Default,
undertakes  to perform  only such  duties as are  specifically  set forth in the
Declaration and, after such Declaration Event of Default, must exercise the same
degree  of care and  skill as a  prudent  person  would  exercise  or use in the
conduct of his or her own  affairs.  Subject to this  provision,  the Trustee is
under  no  obligation  to  exercise  any  of  the  powers  vested  in it by  the
Declaration  at the request of any holder of Preferred  Securities  unless it is
offered  reasonable  indemnity against the costs,  expenses and liabilities that
might be incurred  thereby.  If no Declaration Event of Default has occurred and
is continuing and the Trustee is required to decide between  alternative  causes
of action,  construe ambiguous provisions in the Declaration or is unsure of the
application  of any provision of the  Declaration,  and the matter is not one on
which holders of Preferred  Securities  are entitled  under the  Declaration  to
vote,  then the  Trustee  shall take such action as is directed by Hvide and, if
not so directed,  shall take such action as it deems  advisable  and in the best
interests of the holders of the Preferred  Securities and the Common  Securities
and will have no liability  except for its own bad faith,  negligence or willful
misconduct.

Miscellaneous

         The Company Trustees are authorized and directed to conduct the affairs
of and to operate the Issuer in such a way that the Issuer will not be deemed to
be an  "investment  company"  required  to be  registered  under the  Investment
Company Act or classified as an association  taxable as a corporation for United
States federal income tax purposes and so that the Debentures will be treated as
indebtedness  of Hvide for United States  federal  income tax purposes.  In this
connection,  Hvide and the Company  Trustees are  authorized to take any action,
not inconsistent  with applicable law, the certificate of trust of the Issuer or
the  Declaration,  that  Hvide  and the  Company  Trustees  determine  in  their
discretion  to be  necessary  or desirable  for such  purposes,  as long as such
action does not materially  adversely affect the interests of the holders of the
Preferred Securities.

         Holders  of the  Preferred  Securities  have no  preemptive  or similar
rights.

         The Issuer may not borrow money or issue debt or mortgage or pledge any
of its assets.

                           DESCRIPTION OF THE GUARANTEE

         The Guarantee was executed and delivered by Hvide concurrently with the
issuance  by the  Issuer of the  Preferred  Securities  for the  benefit  of the
holders from time to time of such Preferred Securities.  The Bank of New York is
the trustee ("Guarantee  Trustee") under the Guarantee.  This summary of certain
provisions of the  Guarantee  does not purport to be complete and is subject to,
and  qualified  in its entirety by reference  to, all of the  provisions  of the
Guarantee,  a copy of which has been  filed as an  exhibit  to the  registration
statement.  The  Guarantee  Trustee  holds the  Guarantee for the benefit of the
holders of the Preferred Securities.

General

         Pursuant  to and to the  extent set forth in the  Guarantee,  Hvide has
irrevocably  agreed to pay in full on a  subordinated  basis,  to the extent set
forth herein,  the Guarantee  Payments (as defined  below) to the holders of the
Preferred  Securities,  as and when due,  regardless  of any  defense,  right of
set-off  or  counterclaim  that the  Issuer  may have or assert  other  than the
defense of  payment.  The  following  payments  with  respect  to the  Preferred
Securities, to the extent not paid by or on behalf of the Issuer (the "Guarantee
Payments"),  are  subject  to the  Guarantee:  (i) any  accumulated  and  unpaid
Distributions  required to be paid on the  Preferred  Securities,  to the extent
that the  Issuer has funds on hand  available  therefor  at such time,  (ii) the
redemption price with respect to any Preferred  Securities called for redemption
to the extent that the Issuer has funds on hand available therefor at such time,
or (iii) upon a voluntary or involuntary dissolution,  winding up or liquidation
of the Issuer (unless the Debentures are distributed to holders of the Preferred
Securities), the lesser of (a) the Liquidation Distribution,  to the extent that
the Issuer has funds on hand available therefor at such time, and (b) the amount
of assets of the  Issuer  remaining  available  for  distribution  to holders of
Preferred  Securities.  Hvide's  obligation  to make a Guarantee  Payment may be
satisfied by direct  payment of the required  amounts by Hvide to the holders of
the  Preferred  Securities  or by causing the Issuer to pay such amounts to such
holders.

         The Guarantee is an irrevocable  guarantee on a  subordinated  basis of
the Issuer's obligations under the Preferred Securities, but applies only to the
extent that the Issuer has funds sufficient to make such payments,  and is not a
guarantee  of  collection.  If  Hvide  does not make  interest  payments  on the
Debentures held by the Issuer,  the Issuer will not be able to pay Distributions
on the Preferred Securities and will not have funds legally available therefor.

         Hvide has, through the Guarantee,  the Declaration,  the Debentures and
the Indenture, taken together, fully, irrevocably and unconditionally guaranteed
all of the  Issuer's  obligations  under  the  Preferred  Securities.  No single
document  standing alone or operating in conjunction  with fewer than all of the
other documents constitutes such guarantee. It is only the combined operation of
these  documents  that has the  effect  of  providing  a full,  irrevocable  and
unconditional   guarantee  of  the  Issuer's  obligations  under  the  Preferred
Securities. See "Relationship Among the Preferred Securities, the Debentures and
the Guarantee."

         The  Company   has  also   agreed   separately   to   irrevocably   and
unconditionally  guarantee  the  obligations  of the Issuer with  respect to the
Common  Securities  to the same  extent as the  Guarantee,  except that upon the
occurrence  and during  the  continuation  of a  Declaration  Event of  Default,
holders of  Preferred  Securities  shall have  priority  over  holders of Common
Securities with respect to distributions and payments on liquidation, redemption
or otherwise.

Status of the Guarantee

         The Guarantee  constitutes  an unsecured  obligation of Hvide and ranks
subordinate and junior in right of payment to all other liabilities of Hvide and
ranks pari passu with any  guarantee  now or hereafter  entered into by Hvide in
respect of any  preferred  or  preference  stock of any  affiliate  of Hvide and
senior to the  Common  Stock of Hvide.  The  terms of the  Preferred  Securities
provide  that each  holder by  acceptance  thereof,  consents  and agrees to the
subordination and other provisions of the Guarantee.

         The Guarantee  constitutes a guarantee of payment and not of collection
(i.e., the guaranteed  party may institute a legal  proceeding  directly against
the  Guarantor  to  enforce  its  rights  under  the  Guarantee   without  first
instituting  a legal  proceeding  against  any  other  person  or  entity).  The
Guarantee  is held for the benefit of the holders of the  Preferred  Securities.
The Guarantee will not be discharged except by payment of the Guarantee Payments
in  full to the  extent  not  paid by the  Issuer  or upon  distribution  of the
Debentures to the holders of the Preferred  Securities.  The Guarantee  does not
place a limitation on the amount of additional indebtedness that may be incurred
by Hvide or any of its subsidiaries.

Amendments and Assignment

         Except with  respect to any changes  that do not  materially  adversely
affect the rights of holders of the Preferred  Securities (in which case no vote
will be required),  the Guarantee may not be amended  without the prior approval
of the holders of not less than a majority in  aggregate  liquidation  amount of
such outstanding Preferred Securities. The manner of obtaining any such approval
is as set forth under "Description of the Preferred  Securities--Voting  Rights;
Amendment of the  Declaration."  All guarantees and agreements  contained in the
Guarantee  shall  bind  the  successors,   assigns,   receivers,   trustees  and
representatives  of Hvide and shall  inure to the  benefit of the holders of the
Preferred Securities then outstanding.

Certain Covenants of Hvide

         Hvide has  covenanted in the  Guarantee  that if and so long as (i) the
Issuer is the holder of all the  Debentures,  (ii) a Tax Event in respect of the
Issuer has occurred and is continuing  and (iii) Hvide has elected,  and has not
revoked  such  election,  to pay  Additional  Sums in respect  of the  Preferred
Securities and Common  Securities,  Hvide will pay to the Issuer such Additional
Sums.  Hvide has also  covenanted that it will not, and it will not cause any of
its subsidiaries  to, (i) declare or pay any dividends or  distributions  on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
Hvide's  capital  stock or (ii)  make any  payment  of  principal,  interest  or
premium,  if any,  on or repay  or  repurchase  or  redeem  any debt  securities
(including  guarantees of  indebtedness  for money  borrowed) of Hvide that rank
pari  passu  with or  junior to the  Debentures  (other  than (a) any  dividend,
redemption, liquidation, interest, principal or guarantee payment by Hvide where
the payment is made by way of  securities  (including  capital  stock) that rank
pari passu with or junior to the securities on which such dividend,  redemption,
interest,  principal or guarantee  payment is being made, (b) payments under the
Guarantee,  (c)  purchases of Hvide Class A Common Stock related to the issuance
of Hvide  Class A Common  Stock  under  any of  Hvide's  benefit  plans  for its
directors,  officers  or  employees,  (d) as a result of a  reclassification  of
Hvide's  capital  stock or the exchange or  conversion of one series or class of
Hvide's  capital stock for another series or class of Hvide's  capital stock and
(e) the  purchase of  fractional  interests in shares of Hvide's  capital  stock
pursuant to the  conversion or exchange  provisions of such capital stock or the
security  being  converted  or  exchanged)  if at such time (i) there shall have
occurred

                                                        50

and be continuing  any event of which Hvide has actual  knowledge  that with the
giving of notice or the lapse of time,  or both,  would  constitute  a Debenture
Event of Default,  (ii) Hvide shall be in default with respect to its payment of
any  obligations  under the  Guarantee or (iii) Hvide shall have given notice of
its selection of an Extension  Period as provided in the Indenture  with respect
to the Debentures  and shall not have  rescinded such notice,  or such Extension
Period, or any extension thereof, shall be continuing. Hvide has also covenanted
(i)  for so  long  as  Preferred  Securities  are  outstanding,  not to  convert
Debentures except pursuant to a notice of conversion delivered to the Conversion
Agent  by a  holder  of  Preferred  Securities,  (ii) to  maintain  directly  or
indirectly  100%  ownership  of the Common  Securities,  provided  that  certain
successors which are permitted  pursuant to the Indenture may succeed to Hvide's
ownership of the Common Securities,  (iii) not to voluntarily dissolve, wind-up,
liquidate or terminate the Issuer,  except (a) in connection with a distribution
of the  Debentures to the holders of the Preferred  Securities in liquidation of
the Issuer upon the redemption of all outstanding Preferred Securities or (b) in
connection with certain mergers,  consolidations  or amalgamations  permitted by
the Declaration,  (iv) to maintain the reservation for issuance of the number of
shares of Hvide Class A Common  Stock that would be  required  from time to time
upon the conversion of all of the Debentures  then  outstanding,  (v) to use its
reasonable efforts, consistent with the terms and provisions of the Declaration,
to cause  the  Issuer  to remain  classified  as a  grantor  trust and not as an
association  taxable as a  corporation  for  United  States  federal  income tax
purposes  and (vi) to  deliver  shares  of Hvide  Class A Common  Stock  upon an
election by the holders of the Preferred  Securities  to convert such  Preferred
Securities into Hvide Class A Common Stock.

         As part of the  Guarantee,  Hvide  has  agreed  that it will  honor all
obligations  described  therein  relating to the  conversion  or exchange of the
Preferred Securities into or for Hvide Class A Common Stock or Debentures.

Guarantee Events of Default

         An event of default under the Guarantee  will occur upon the failure of
Hvide to perform any of its payment or other obligations thereunder. The holders
of a majority in aggregate  liquidation amount of the Preferred  Securities have
the right to direct the time,  method and place of conducting any processing for
any remedy available to the Guarantee  Trustee in respect of the Guarantee or to
direct the exercise of any trust or power  conferred upon the Guarantee  Trustee
under the Guarantee.

         If the Guarantee Trustee fails to enforce the Guarantee,  any holder of
the Preferred Securities may institute a legal proceeding directly against Hvide
to enforce its rights under the  Guarantee  without  first  instituting  a legal
proceeding  against the Issuer,  the  Guarantee  Trustee or any other  person or
entity.  In addition,  any record holder of Preferred  Securities shall have the
right, which is absolute and unconditional, to proceed directly against Hvide to
obtain Guarantee  Payments,  without first waiting to determine if the Guarantee
Trustee has enforced the Guarantee or instituting a legal proceeding against the
Issuer,  the Guarantee  Trustee or any other person or entity.  Hvide has waived
any right or remedy to  require  that any  action be brought  just  against  the
Issuer, or any other person or entity before proceeding directly against Hvide.

         Hvide,  as  guarantor,  is required to file annually with the Guarantee
Trustee a certificate  as to whether or not Hvide is in compliance  with all the
conditions and covenants applicable to it under the Guarantee.


                                                        51

<PAGE>



Information Concerning the Guarantee Trustee

         The Guarantee Trustee, other than during the occurrence and continuance
of a default by Hvide in  performance  of the  Guarantee,  undertakes to perform
only such  duties as are  specifically  set forth in the  Guarantee  and,  after
default with respect to the Guarantee, must exercise the same degree of care and
skill as a prudent person would exercise or use under the  circumstances  in the
conduct of his or her own  affairs.  Subject to this  provision,  the  Guarantee
Trustee is under no obligation to exercise any of the powers vested in it by the
Guarantee  at the  request of any holder of  Preferred  Securities  unless it is
offered  reasonable  indemnity against the costs,  expenses and liabilities that
might be incurred thereby.

Termination of the Guarantee

         The Guarantee will terminate and be of no further force and effect upon
full payment of the  redemption  price of the  Preferred  Securities,  upon full
payment  of the  amounts  payable  upon  liquidation  of the  Issuer,  upon  the
distribution,  if any, of Hvide Class A Common Stock to the holders of Preferred
Securities  in  respect  of  the  conversion  of  all  such  holders'  Preferred
Securities into Hvide Class A Common Stock or upon distribution of Debentures to
the holders of the  Preferred  Securities  in exchange for all of the  Preferred
Securities.  The Guarantee  will continue to be effective or will be reinstated,
as the case may be,  if at any time any  holder  of  Preferred  Securities  must
restore payment of any sums under such Preferred Securities or the Guarantee.

Governing Law

         The Guarantee is governed by and construed in accordance  with the laws
of the State of New York.

                        DESCRIPTION OF THE DEBENTURES

         The Debentures are to be issued under a Junior  Subordinated  Indenture
(the  "Indenture")  between  Hvide and The Bank of New  York,  as  trustee  (the
"Indenture  Trustee"),  copies of which will be available for  inspection at the
corporate trust office of the Indenture Trustee in New York, New York. The terms
of the Debentures  include those stated in the Indenture and made a part thereof
by reference to the Trust  Indenture Act in effect on the date of the Indenture.
This summary of certain terms and provisions of the Debentures and the Indenture
does not  purport to be  complete  and is subject  to, and is  qualified  in its
entirety by reference to, the Indenture.  Whenever  particular  defined terms of
the Indenture are referred to herein, such defined terms are incorporated herein
by reference.

General

         The  Debentures  are unsecured and rank junior and are  subordinate  in
right of payment to all Senior  Debt of Hvide.  The  Debentures  are  limited in
aggregate  principal amount to $118.5 million,  such amount being the sum of the
$115.0 million aggregate stated liquidation  amount of the Preferred  Securities
and the $3.5  million  capital  contributed  by Hvide in exchange for the Common
Securities.  The  Indenture  does not limit the  incurrence or issuance of other
secured or unsecured debt of Hvide,  whether under the Indenture or any existing
or other  indenture  that Hvide may enter into in the future or  otherwise.  See
"--Subordination."


                                                        52

<PAGE>



         Concurrently with the issuance of the Preferred Securities,  the Issuer
invested the proceeds thereof and the consideration paid by Hvide for the Common
Securities in the Debentures.  The Debentures are in the principal  amount equal
to the aggregate  stated  liquidation  amount of the Preferred  Securities  plus
Hvide's concurrent investment in the Common Securities.

         The  Debentures  are not subject to any  sinking  fund  provision.  The
entire  principal  amount of the  Debentures  will  mature,  and  become due and
payable,  together  with any accrued and unpaid  interest  thereon,  on June 15,
2012.

Interest

         The  Debentures  bear  interest at the annual rate of 6 1/2% per annum,
payable quarterly in arrears on January 1, April 1, July 1 and October 1 of each
year,  commencing on October 1, 1997 (each, an "Interest  Payment Date"), to the
person in whose name each  Debenture is  registered  at the close of business on
the  fifteenth  day  (whether or not a Business  Day)  preceding  such  Interest
Payment Date (the "Regular Record Date"),  subject to certain exceptions.  It is
anticipated that, until the Liquidation,  if any, of the Issuer,  each Debenture
will be held in the name of the  Trustee in trust for the benefit of the holders
of the Preferred  Securities and the Common  Securities.  The amount of interest
payable for any period will be computed on the basis of a 360-day year of twelve
30-day  months.  In the event that any date on which  interest is payable on the
Debentures is not a Business  Day, then payment of the interest  payable on such
date will be made on the next succeeding day that is a Business Day (and without
any interest or other  payment in respect of any such delay) except that if such
Business Day is in the next succeeding calendar year, then such payment shall be
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such Interest  Payment Date.  Accrued  interest that is
not paid on the applicable  Interest Payment Date will bear additional  interest
on the amount  thereof (to the extent  permitted  by law) at the stated rate per
annum,  compounded  quarterly.  The term "interest" as used herein shall include
quarterly interest payments, interest on quarterly interest payments not paid on
the applicable Interest Payment Date, and Additional Sums, as applicable.

Global Securities

         If  distributed  to holders of the  Preferred  Securities in connection
with the involuntary or voluntary dissolution,  winding-up or liquidation of the
Issuer as a result of the occurrence of a Special Event,  the Debentures will be
issued  in the  same  form as the  Preferred  Securities  that  such  Debentures
replace.  Any  Global  Certificate  will  be  replaced  by  one or  more  global
securities (each, a "Global Security")  registered in the name of the depositary
or its nominee.  Except under the limited  circumstances  described  below,  the
Debentures  represented by the Global Security will not be exchangeable for, and
will not otherwise be issuable as,  Debentures in  definitive  form.  The Global
Securities  described above may not be transferred except by the depository to a
nominee of the depository or by a nominee of the depository to the depository or
another nominee of the depository or to a successor depository or its nominee.

         The laws of some  jurisdictions  require  that  certain  purchasers  of
securities  take physical  delivery of securities in definitive  form. Such laws
may impair the ability to transfer beneficial interests in a Global Security.

         Except as provided  below,  owners of beneficial  interests in a Global
Security  will not be entitled to receive  physical  delivery of  Debentures  in
definitive form and will not be considered the holders

                                                        53

<PAGE>



thereof for any purpose under the Indenture, and no Global Security representing
Debentures  shall be  exchangeable,  except for another Global  Security of like
denomination  and tenor to be  registered  in the name of the  depository or its
nominee  or  to  a  successor  depository  or  its  nominee.  Accordingly,  each
beneficial owner of Preferred  Securities must rely on the procedures of DTC, or
if such  person  is not a  participant,  on the  procedures  of the  participant
through  which such person owns its  interest to exercise any rights of a holder
under the Indenture.

         If Debentures  are  distributed  to holders of Preferred  Securities in
liquidation  of such holders'  interests in the Issuer and a Global  Security is
issued, DTC will act as securities depository for the Debentures  represented by
such Global  Security.  For a  description  of DTC and the general  terms of the
depository arrangements,  see "Description of the Preferred  Securities--Certain
Book-Entry  Procedures  for  Global  Certificates."  As  of  the  date  of  this
Prospectus,  the  description  therein  of DTC's  book-entry  system  and  DTC's
practices as they relate to  purchases,  transfers,  notices and  payments  with
respect to the Preferred  Securities apply in all material  respects to any debt
obligations  represented by one or more Global Securities held by DTC. Hvide may
appoint a successor to DTC or any successor  depository in the event DTC or such
depository  is unable or unwilling  to continue as a  depository  for the Global
Securities.

         None  of  Hvide,  the  Indenture  Trustee,  any  Paying  Agent  or  the
Securities Registrar will have any responsibility or liability for any aspect of
the  records  relating to or payments  made on account of  beneficial  ownership
interests  of  the  Global   Security   representing   such  Debentures  or  for
maintaining,  supervising or reviewing any records  relating to such  beneficial
ownership interests.

         A Global  Security shall be exchangeable  for Debentures  registered in
the names of persons  other  than DTC or its  nominee  only if (i) DTC  notifies
Hvide that it is unwilling or unable to continue as a depository for such Global
Debenture and no successor  depositary shall have been appointed by Hvide within
90 days, or if at any time DTC ceases to be a "clearing agency" registered under
the  Exchange Act at a time when DTC is required to be so  registered  to act as
such  depository and no such successor  depository has been appointed  within 90
days by the  Company,  (ii) Hvide in its sole  discretion  determines  that such
Global Security shall be so exchangeable, or (iii) there shall have occurred and
be  continuing  an Event of Default  with respect to such Global  Security.  Any
Global Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for definitive  certificates  registered in such names as DTC shall
direct.  It is expected  that such  instructions  will be based upon  directions
received by DTC from its  participants  with respect to ownership of  beneficial
interests in such Global  Security.  In the event that  Debentures are issued in
definitive  form, such Debentures will be in  denominations  of $50 and integral
multiples  thereof and may be transferred or exchanged at the offices  described
in "--Payment and Paying Agent" below.

Payment and Paying Agent

         Payments on Debentures represented by a Global Security will be made to
DTC, as the depositary for the Debentures. In the event Debentures are issued in
definitive  form,  principal  of and  premium,  if  any,  and  any  interest  on
Debentures will be payable,  the transfer of the Debentures will be registrable,
and the Debentures will be exchangeable for Debentures of other denominations of
a like  aggregate  principal  amount at the  corporate  office of the  Indenture
Trustee in the City of New York or at the office of such Paying  Agent or Paying
Agents as Hvide may designate, except that at the option of Hvide payment of any
interest may be made (i) by check  mailed to the address of the Person  entitled
thereto as

                                                        54

<PAGE>



such address shall appear in the Securities Register or (ii) by wire transfer to
an  account  maintained  by the Person  entitled  thereto  as  specified  in the
Securities  Register,  provided  that  proper  transfer  instructions  have been
received by the Regular Record Date.  Payment of any interest on Debentures will
be made to the Person in whose name such  Debentures are registered at the close
of business on the Regular Record Date for such interest,  except in the case of
Defaulted  Interest.  The Regular  Record Date for the  interest  payable on any
Interest Payment Date shall be the fifteenth day (whether or not a Business Day)
next  preceding  such  Interest  Payment Date.  Hvide may at any time  designate
additional Paying Agents or rescind the designation of any Paying Agent.

         Any monies deposited with the Indenture Trustee or any Paying Agent, or
then held by Hvide in trust, for the payment of the principal of and premium, if
any, or interest on any Debentures  and remaining  unclaimed for two years after
such  principal  and  premium,  if any, or  interest  has become due and payable
shall,  at the  request  of Hvide,  be  repaid  to Hvide and the  holder of such
Debentures shall thereafter look, as a general unsecured creditor, only to Hvide
for payment thereof.

Option to Extend Interest Payment Period

         So long as no Event of Default  under the Indenture has occurred and is
continuing,  Hvide has the right  under the  Indenture  to defer the  payment of
interest  on the  Debentures  at any time or from time to time for a period  not
exceeding  20  consecutive  quarters  with  respect  to each  Extension  Period,
provided that no Extension  Period may extend beyond the stated  maturity of the
Debentures.  At the end of such  Extension  Period,  Hvide must pay all interest
then accrued and unpaid  (together  with  interest  thereon at the stated annual
rate, compounded  quarterly,  to the extent permitted by applicable law). During
an Extension Period,  interest will continue to accrue and holders of Debentures
(or  holders  of  Preferred   Securities  while  the  Preferred  Securities  are
outstanding)  will be  required  to accrue  interest  income for  United  States
federal    income   tax   purposes.    See   "Certain    Federal    Income   Tax
Consequences--Original Issue Discount."

         During any such Extension Period, Hvide shall not, and shall not permit
any  subsidiary  to, (i) declare or pay any  dividends or  distributions  on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
Hvide's  capital  stock or (ii)  make any  payment  of  principal,  interest  or
premium,  if  any,  on or  repay,  repurchase  or  redeem  any  debt  securities
(including  guarantees of  indebtedness  for money  borrowed) of Hvide that rank
pari passu with or junior to the Debentures  (other than in the case of both (i)
and (ii) (a) any  dividend,  redemption,  liquidation,  interest,  principal  or
guarantee  payment  by Hvide  where  the  payment  is made by way of  securities
(including  capital stock) that rank pari passu with or junior to the securities
on which such dividend, redemption,  interest, principal or guarantee payment is
being made,  (b) payments  under the  Guarantee,  (c) purchases of Hvide Class A
Common Stock  related to the issuance of Hvide Class A Common Stock under any of
Hvide's benefit plans for its directors,  officers or employees, (d) as a result
of a reclassification  of Hvide's capital stock or the exchange or conversion of
one  series or class of Hvide's  capital  stock for  another  series or class of
Hvide's capital stock, and (e) the purchase of fractional interests in shares of
Hvide's capital stock pursuant to the conversion or exchange  provisions of such
capital stock or the security being converted or exchanged).

         Prior  to the  termination  of any such  Extension  Period,  Hvide  may
further extend the interest  payment period,  provided that no Extension  Period
may exceed 20 consecutive  quarters or extend beyond the stated  maturity of the
Debentures. Upon the termination of any such Extension Period and the

                                                        55

<PAGE>



payment of all amounts then due on any Interest Payment Date, Hvide may elect to
begin a new  Extension  Period  subject to the above  requirements.  No interest
shall be due and payable during an Extension Period,  except at the end thereof.
Hvide shall give the Trustee, the Delaware Trustee, the Company Trustees and the
Indenture  Trustee notice of its election to begin any Extension Period at least
one  Business  Day  prior to the  earlier  of (i) the  record  date for the date
Distributions  on the Preferred  Securities (or, if no Preferred  Securities are
outstanding,  for the date interest on the  Debentures)  would have been payable
except for the  election  to begin such  Extension  Period and (ii) the date the
Trustee is (or,  if no  Preferred  Securities  are  outstanding,  the  Indenture
Trustee  is)  required  to give  notice to The Nasdaq  National  Market or other
applicable  self-regulatory   organization  or  to  holders  of  such  Preferred
Securities (or, if no Preferred  Securities are  outstanding,  to the holders of
such Debentures) of such election.  The Indenture  Trustee and the Trustee shall
give notice of Hvide's  election to begin an Extension  Period to the holders of
the Debentures and the Preferred Securities, respectively.

Mandatory Redemption

         Upon  repayment  at  maturity or as a result of  acceleration  upon the
occurrence of a Debenture Event of Default, Hvide will redeem the Debentures, in
whole but not in part,  at a  redemption  price  equal to 100% of the  principal
amount  thereof,  together  with any accrued and unpaid  interest  thereon.  Any
payment  pursuant to this provision  shall be made prior to 12:00 noon, New York
City time, on the date of such repayment or  acceleration  or at such other time
on such earlier date as the parties thereto shall agree.  The Debentures are not
entitled to the benefit of any sinking fund or,  except as set forth above or as
a result of acceleration, any other provision for mandatory prepayment.

Optional Redemption

         On and after July 2, 2000, and subject to the next succeeding sentence,
Hvide  will have the  right,  at any time and from time to time,  to redeem  the
Debentures, in whole or in part, upon notice given as provided below, during the
twelve-month  periods  beginning on July 2 in each of the following years and at
the  indicated  redemption  prices  (expressed  as a percentage of the principal
amount of the Debentures being  redeemed),  together with any accrued but unpaid
interest on the portion being redeemed.

</TABLE>

         For so  long  as  the  Issuer  is the  holder  of all  the  outstanding
Debentures,  the proceeds of any such  redemption  will be used by the Issuer to
redeem  Preferred  Securities  and Common  Securities in  accordance  with their
terms. Hvide may not redeem the Debentures in part unless all accrued and unpaid
interest has been paid in full on all outstanding  Debentures.  See "Description
of the Preferred Securities--Optional Redemption."



                                                        56

<PAGE>



         Hvide also shall  have the right to redeem the  Debentures  at any time
after  July  2,  2000  upon  the  occurrence  of a Tax  Event  as  described  in
"Description of the Preferred  Securities--Special Event Exchange or Redemption"
at a redemption  price equal to the principal  amount thereof,  plus any accrued
and unpaid interest.

         If at any time following the Conversion  Expiration  Date, less than 5%
of  the  original   aggregate   principal  amount  of  the  Debentures   remains
outstanding,  such  Debentures  shall be redeemable  at the option of Hvide,  in
whole but not in part,  at a  redemption  price  equal to the  principal  amount
thereof, plus any accrued and unpaid interest.

Redemption Procedures

         Notices of any redemption of the Debentures and the procedures for such
redemption  shall be as provided with respect to the Preferred  Securities under
"Description of the Preferred Securities--Redemption  Procedures." Notice of any
redemption  will be mailed at least 30 days but not more than 60 days before the
redemption  date to each holder of Debentures  to be redeemed at its  registered
address.  Unless Hvide defaults in payment of the redemption price, on and after
the redemption  date interest  ceases to accrue and  conversion  rights cease on
such Debentures or portions thereof called for redemption.

Distribution of Debentures

         At any time, Hvide will have the right to dissolve the Issuer and cause
the Debentures to be  distributed to the holders of the Preferred  Securities in
liquidation of the Issuer after  satisfaction of liabilities to creditors of the
Issuer as provided by  applicable  law. If  distributed  to holders of Preferred
Securities in  liquidation,  the Debentures will initially be issued in the form
of one or more Global  Securities  and DTC, or any successor  depositary for the
Preferred  Securities,  will  act  as  depositary  for  the  Debentures.  It  is
anticipated  that  the  depositary  arrangements  for the  Debentures  would  be
substantially  identical to those in effect for the Preferred Securities.  There
can be no  assurance  as to the  market  price  of any  Debentures  that  may be
distributed to the holders of Preferred Securities. For a description of DTC and
the terms of the  depositary  arrangement,  see  "Description  of the  Preferred
Securities--Certain Book-Entry Procedures for Global Certificates."

Conversion of the Debentures

         The  Debentures  are  convertible  at the option of the  holders of the
Debentures  into Hvide Class A Common  Stock,  at any time prior to  redemption,
maturity or the  Conversion  Expiration  Date,  initially  at the rate of 1.7544
shares  of Hvide  Class A Common  Stock  for each  $50 in  principal  amount  of
Debentures  (equivalent to a conversion price of $28.50 per share of Hvide Class
A Common Stock),  subject to the conversion  price  adjustments  described under
"Description  of the  Preferred  Securities--Conversion  Rights." The Issuer has
covenanted  for so long  as the  Preferred  Securities  are  outstanding  not to
convert  Debentures  except pursuant to a notice of conversion  delivered to the
Conversion  Agent by a holder of Preferred  Securities.  Upon  surrender of such
Preferred  Securities to the Conversion  Agent for  conversion,  the Issuer will
distribute the commensurate principal amount of the Debentures to the Conversion
Agent  on  behalf  of the  holder  of every  Preferred  Security  so  converted,
whereupon the Conversion  Agent will convert such  Debentures into Hvide Class A
Common  Stock on behalf of such holder.  Hvide's  delivery to the holders of the
Debentures (through the Conversion Agent)

                                                        57

<PAGE>



of the  fixed  number of shares of Hvide  Class A Common  Stock  into  which the
Debentures are convertible  (together with the cash payment,  if any, in lieu of
fractional  shares)  will be deemed to  satisfy  Hvide's  obligation  to pay the
principal  amount  of the  Debentures,  and  the  accrued  and  unpaid  interest
attributable to the period from the last date to which interest has been paid or
duly provided for; provided,  however,  that if any Debenture is converted on or
after a Regular Record Date for payment of interest, the interest payable on the
related  Interest  Payment Date with respect to such Debenture  shall be paid to
the Issuer (which will  distribute  such interest to the holder) or other holder
of Debentures, as the case may be, despite such conversion;  provided,  further,
that if a redemption date falls between such Regular Record Date and the related
Interest Payment Date, the amount of such payment shall include interest accrued
to, but excluding, such redemption date.

         For  possible  restrictions  on the  ability of  non-U.S.  citizens  to
convert Debentures into Class A Common Stock, see "Risk  Factors--Restriction on
Foreign  Ownership of Common  Stock;  Possible  Inability  to Convert  Preferred
Securities and Debentures."

Expiration of Conversion Rights

         The conversion rights of any Debentures held by the Issuer shall expire
upon the expiration of the conversion rights of the Preferred  Securities on the
terms described above under "Description of the Preferred Securities--Conversion
Rights."

Modification of Indenture

         From time to time,  Hvide and the  Indenture  Trustee may,  without the
consent of the holders of Debentures,  amend,  waive or supplement the Indenture
for  specified  purposes,  including,  among other things,  curing  ambiguities,
defects or  inconsistencies  (provided  that any such action does not materially
adversely  affect the interest of the holders of the Debentures,  or the holders
of the Preferred  Securities so long as they remain outstanding) and qualifying,
or maintaining  the  qualification  of, the Indenture  under the Trust Indenture
Act.  The  Indenture  contains  provisions  permitting  Hvide and the  Indenture
Trustee,  with the  consent  of the  holders  of not  less  than a  majority  in
principal  amount of the  outstanding  Debentures,  to modify the Indenture in a
manner  affecting the rights of the holders of the Debentures;  provided that no
such  modification  may,  without the consent of the holder of each  outstanding
Debenture  so affected,  (i) change the stated  maturity of the  Debentures,  or
reduce  the  principal  amount  thereof,  or reduce any  premium  payable on the
redemption thereof, or reduce the rate or extend the time of payment of interest
thereon  (other than  deferrals of the  payments of interest as described  under
"--Option to Extend Interest  Payment  Period") or impair any right to institute
suit  for  the  enforcement  of  any  such  payment,  or  adversely  affect  the
subordination provisions of the Indenture or any right to convert any Debentures
or (ii) reduce the percentage of principal amount of Debentures,  the holders of
which  are  required  to  consent  to any such  modification  of the  Indenture,
provided that, so long as any of the Preferred Securities remain outstanding, no
such  modification  may be made  that  adversely  affects  the  holders  of such
Preferred  Securities  in  any  material  respect,  and  no  termination  of the
Indenture  may  occur,  and no  waiver  of any  Debenture  Event of  Default  or
compliance  with any covenant under the Indentures  shall be effective,  without
the prior consent of the holders of at least a majority in aggregate

                                                        58

<PAGE>



liquidation amount of the Preferred Securities then outstanding unless and until
the principal of the Debentures and all accrued and unpaid interest  thereon has
been paid in full; provided,  however,  that where a consent under the Indenture
would require the consent of each holder of Debentures affected thereby, no such
consent  shall be given by the Trustee  without the prior consent of each holder
of Preferred Securities.

Debenture Events of Default

         The Indenture provides that any one or more of the following  described
events that has occurred and is  continuing  constitutes  a "Debenture  Event of
Default"  with  respect to such  Debentures:  (i) failure for 30 days to pay any
interest on the Debentures, when due (subject to the deferral of any due date in
the case of an  Extension  Period);  or (ii)  failure  to pay any  principal  or
premium,  if  any,  on  the  Debentures  when  due  whether  at  maturity,  upon
redemption,  by declaration  or otherwise;  or (iii) failure by Hvide to deliver
shares of Hvide Class A Common Stock upon an appropriate  election by holders of
Debentures to convert such Debentures;  or (iv) failure to observe or perform in
any material  respect certain other covenants  contained in the Indenture for 90
days  after  written  notice  to Hvide  from  the  Indenture  Trustee  or to the
Indenture  Trustee  and Hvide  from the  holders  of at least  25% in  aggregate
outstanding  principal  amount of such Debentures or by the holder or holders of
at least 25% in the aggregate  outstanding  liquidation  amount of the Preferred
Securities;  or (v) the  dissolution,  winding up or  termination  of the Trust,
except in  connection  with the  distribution  of  Debentures  to the holders of
Preferred  Securities  in  liquidation  of the Trust upon the  redemption of all
outstanding  Preferred  Securities  and  in  connection  with  certain  mergers,
consolidations  or amalgamations  permitted by the Declaration;  or (vi) certain
events in bankruptcy, insolvency or reorganization of Hvide.

         The holders of a majority in aggregate  outstanding principal amount of
the Debentures have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Indenture Trustee.  The Indenture
Trustee or the holders of not less than 25% in aggregate principal amount of the
Debentures   then   outstanding  may  declare  the  principal  due  and  payable
immediately upon a Debenture Event of Default, and, should the Indenture Trustee
or the holders of the Debentures fail to make such  declaration,  the holders of
at least 25% in aggregate  liquidation  amount of the Preferred  Securities then
outstanding  shall have such  right.  The  holders of a  majority  in  aggregate
outstanding  principal  amount of the  Debentures  may annul  and  rescind  such
declaration if the default  (other than the  non-payment of the principal of the
Debentures which has become due solely by such  acceleration) has been cured and
a sum sufficient to pay all matured  installments  of interest and principal due
otherwise than by  acceleration  has been  deposited with the Indenture  Trustee
and,  should  the  holders  of the  Debentures  fail to annul and  rescind  such
declaration,  the holders of a majority in aggregate  liquidation  amount of the
Preferred Securities then outstanding shall have such right.

         The holders of a majority in aggregate  outstanding principal amount of
the  Debentures  affected  thereby  may,  on  behalf of the  holders  of all the
Debentures, waive any past default, except a default in the payment of principal
or interest  (unless such default has been cured and a sum sufficient to pay all
matured   installments   of  interest  and  principal  due  otherwise   than  by
acceleration  has been  deposited  with the  Indenture  Trustee) or a default in
respect of a covenant or provision which under the Indenture  cannot be modified
or amended  without  the  consent of the  holder of each  outstanding  Debenture
affected thereby

                                                        59

<PAGE>



and,  should the holders of the Debentures  fail to annul such  declaration  and
waive such default, the holders of a majority in aggregate liquidation amount of
the  Preferred  Securities  shall have such  right.  Hvide is  required  to file
annually with the Indenture  Trustee a certificate as to whether or not Hvide is
in compliance  with all the conditions and covenants  applicable to it under the
Indenture.

         In case a Debenture  Event of Default  shall occur and be continuing as
to the  Debentures,  the Trustee will have the right to declare the principal of
and the  interest on the  Debentures  and any other  amounts  payable  under the
Indenture to be  forthwith  due and payable and to enforce its other rights as a
creditor with respect to the Debentures.

Enforcement of Certain Rights by Holders of Preferred Securities

         If a Debenture Event of Default has occurred and is continuing and such
event is attributable to the failure of Hvide to pay interest,  premium, if any,
or  principal  on the  Debentures  on the date such  interest  or  principal  is
otherwise  payable,  a holder of  Preferred  Securities  may  institute a Direct
Action for payment after the respective  due date  specified in the  Debentures.
Hvide may not amend the  Indenture  to  remove  the  foregoing  right to bring a
Direct  Action  without the prior  written  consent of the holders of all of the
Preferred  Securities.  Notwithstanding  any  payment  made  to such  holder  of
Preferred  Securities by Hvide in connection  with a Direct Action,  Hvide shall
remain  obligated to pay the principal of or interest on the Debentures  held by
the Issuer or the  Trustee and Hvide  shall be  subrogated  to the rights of the
holder of such  Preferred  Securities  with respect to payments on the Preferred
Securities  in the extent of any  payments  made by Hvide to such  holder in any
Direct Action.

Consolidation, Merger, Sale of Assets and Other Transactions

         The Indenture  provides that Hvide shall not consolidate  with or merge
into any other Person,  continue in another jurisdiction or convey,  transfer or
lease its properties and assets  substantially as an entirety to any Person, and
no Person  shall  consolidate  with or merge into Hvide or convey,  transfer  or
lease its properties and assets substantially or as an entirety to Hvide, unless
(i) in case Hvide  consolidates  with or merges into another  Person or conveys,
transfers or leases its  properties and assets  substantially  as an entirety to
any  Person,  the  successor  Person is  organized  under the laws of the United
States or any state or the  District  of  Columbia,  and such  successor  Person
expressly assumes Hvide's obligations on the Debentures;  (ii) immediately after
giving effect thereto, no Debenture Event of Default,  and no event which, after
notice or lapse of time or both,  would  become a  Debenture  Event of  Default,
shall have happened and be continuing; (iii) in the case of the Debentures, such
transaction is permitted  under the  Declaration and Guarantee and does not give
rise to any  breach or  violation  of the  Declaration  or  Guarantee;  and (iv)
certain other conditions as prescribed in the Indenture are met.

         The general  provisions of the  Indenture do not afford  holders of the
Debentures  protection in the event of a highly  leveraged or other  transaction
involving Hvide that may adversely affect holders of the Debentures.

Expenses of Issuer

         The  Indenture  provides  that  Hvide  will pay all  fees and  expenses
related  to (i)  the  Original  Offering  of the  Preferred  Securities  and the
Debentures,  (ii) the  organization,  maintenance  and dissolution of the Trust,
(iii) the  retention  of the Issuer  Trustees,  the  Guarantee  Trustee  and the
Indenture Trustee

                                                        60

<PAGE>



and (iv) the  enforcement  by the  Trustee of the  rights of the  holders of the
Preferred  Securities.  The  payment  of such  fees and  expenses  is fully  and
unconditionally guaranteed by Hvide.

Satisfaction and Discharge

         The Indenture  provides that when,  among other things,  all Debentures
not  previously  delivered to the Indenture  Trustee for  cancellation  (i) have
become due and  payable  or (ii) will  become  due and  payable at their  stated
maturity  within  one year or are to be called  for  redemption  within one year
under  irrevocable  agreements  satisfactory  to the  Indenture  Trustee for the
giving of notice of redemption,  and Hvide irrevocably  deposits or causes to be
deposited with the Indenture  Trustee trust funds, in trust, for the purpose and
in an amount in the currency or currencies in which the  Debentures  are payable
sufficient to pay and discharge the entire  indebtedness  on the  Debentures not
previously  delivered  to  the  Indenture  Trustee  for  cancellation,  for  the
principal and premium, if any, and interest to the date of the deposit or to the
stated  maturity,  as the case may be,  then the  Indenture  will cease to be of
further  effect  (except  as to  Hvide's  obligations  to pay all other sums due
pursuant  to  the  Indenture,  to  honor  any  conversion  rights  prior  to the
redemption date or maturity date, and to provide the officers'  certificates and
opinions  of  counsel  described  therein),  and  Hvide  will be  deemed to have
satisfied and discharged the Indenture.

Subordination

         In the  Indenture,  Hvide has covenanted and agreed that any Debentures
issued  thereunder  will be  subordinate  and  junior in right of payment to all
Senior  Debt of Hvide  whether  now  existing or  hereafter  incurred.  Upon any
payment  or   distribution   of  assets  to  creditors  upon  any   liquidation,
dissolution,   winding-up,   reorganization,   assignment  for  the  benefit  of
creditors,   marshaling   of  assets  or  any   bankruptcy,   insolvency,   debt
restructuring  or similar  proceedings  in  connection  with any  insolvency  or
bankruptcy  proceeding  of  Hvide,  the  holders  of Senior  Debt will  first be
entitled to receive  payment in full of principal  of and  premium,  if any, and
interest,  if any,  on such Senior  Debt  before the  Trustee,  on behalf of the
holders of the Debentures,  will be entitled to receive or retain any payment in
respect of the  principal  of and premium,  if any, or interest,  if any, on the
Debentures.

         In the event of the acceleration of the maturity of any Debentures, the
holders of all Senior Debt  outstanding  at the time of such  acceleration  will
first  be  entitled  to  receive  payment  in full of all  amounts  due  thereon
(including any amounts due upon  acceleration)  before the holders of Debentures
will be entitled to receive or retain any payment in respect of the principal of
or premium, if any, or interest, if any, on the Debentures.

         No payment on account of principal (or premium, if any) or interest, if
any, in respect of the  Debentures  may be made if there shall have occurred and
be  continuing a default in any payment with respect to Senior Debt, or an event
of default with respect to any Senior Debt resulting in the  acceleration of the
maturity thereof, or if any judicial proceeding shall be pending with respect to
any such default.

         "Debt" means, with respect to any Person, whether recourse is to all or
a portion of the assets of such Person and whether or not contingent,  (i) every
obligation  of such Person for money  borrowed;  (ii) every  obligation  of such
Person  evidenced  by bonds,  debentures,  notes or other  similar  instruments,
including  obligations  incurred in connection with the acquisition of property,
assets or businesses;  (iii) every reimbursement  obligation of such Person with
respect to letters of credit,  bankers' acceptances or similar facilities issued
for the account of such Person; (iv) every obligation of such Person issued or

                                                        61

assumed as the deferred  purchase  price of property or services (but  excluding
trade accounts payable or accrued  liabilities arising in the ordinary course of
business);  (v) every  capital lease  obligation of such Person;  and (vi) every
obligation of the type referred to in clauses (i) through (v) of another  Person
and all dividends of another person the payment of which,  in either case,  such
Person  has  guaranteed  or for which  such  Person is  responsible  or  liable,
directly or indirectly, as obligor or otherwise.

         "Senior  Debt"  means  the  principal  of (and  premium,  if  any)  and
interest,  if any  (including  interest  accruing  on or after the filing of any
petition in  bankruptcy or for  reorganization  relating to Hvide whether or not
such claim for post-petition interest is allowed in such proceeding), on Debt of
Hvide,  whether  incurred on or prior to the date of the Indenture or thereafter
incurred,  unless, in the instrument creating or evidencing the same or pursuant
to which the same is outstanding,  it is provided that such  obligations are not
superior  in right of payment to the  Debentures  or to other Debt which is pari
passu with, or subordinated to, the Debentures;  provided,  however, that Senior
Debt shall not be deemed to include:  (i) any Debt of Hvide which, when incurred
and without  respect to any election  under  Section  1111(b) of the  Bankruptcy
Code,  was  without  recourse  to  Hvide,  (ii)  any Debt of Hvide to any of its
subsidiaries, (iii) Debt to any employee of Hvide, (iv) any liability for taxes,
and (v) Debt or other  monetary  obligations  to trade  creditors  or assumed by
Hvide  or  any  of its  subsidiaries  in the  ordinary  course  of  business  in
connection with the obtaining of goods, materials or services.

         The Indenture  places no limitation on the amount of additional  Senior
Debt that may be incurred by Hvide.

Governing Law

         The  Indenture  and the  Debentures  are  governed by and  construed in
accordance with the laws of the State of New York.

Information Concerning the Indenture Trustee

         The  Indenture  Trustee is under no  obligation  to exercise any of the
powers vested in it by the Indenture at the request of any holder of Debentures,
unless offered reasonable  indemnity by such holder against the costs,  expenses
and liabilities  which might be incurred  thereby.  The Indenture Trustee is not
required to expend or risk its own funds or otherwise  incur personal  financial
liability in the performance of its duties if the Indenture  Trustee  reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.

                          RELATIONSHIP AMONG THE PREFERRED
                     SECURITIES, THE DEBENTURES AND THE GUARANTEE

Full and Unconditional Guarantee

         Payments  of  Distributions  and  other  amounts  due on the  Preferred
Securities (to the extent the Issuer has funds available for the payment of such
Distributions)  are  irrevocably  guaranteed  by Hvide as and to the  extent set
forth under "Description of the Guarantee." Taken together,  Hvide's obligations
under the Debentures,  the Indenture, the Declaration and the Guarantee provide,
in the aggregate, a full, irrevocable and unconditional guarantee of payments of
Distributions  and other  amounts  due on the  Preferred  Securities.  No single
document standing alone or operating in conjunction with fewer than all

                                                        62

<PAGE>



of the other  documents  constitutes  such  guarantee.  It is only the  combined
operation  of  these  documents  that  has  the  effect  of  providing  a  full,
irrevocable and  unconditional  guarantee of the Issuer's  obligations under the
Preferred Securities.  If and to the extent that Hvide does not make payments on
the Debentures,  the Issuer will not pay  Distributions  or other amounts due on
the Preferred Securities.  The Guarantee does not cover payment of Distributions
when the Issuer does not have  sufficient  funds to pay such  Distributions.  In
such event,  a holder of  Preferred  Securities  may  institute a Direct  Action
directly  against Hvide to enforce payment of such  Distributions to such holder
after the respective due dates. The obligations of Hvide under the Guarantee are
subordinate  and junior in right of payment to all other  liabilities  of Hvide;
and pari passu with any  guarantee  now or  hereafter  entered  into by Hvide in
respect of any preferred or preference stock of any affiliate of Hvide.

Sufficiency of Payments

         As long as payments of interest and other payments are made when due on
the  Debentures,  such payments will be  sufficient to cover  Distributions  and
other  payments  due on the  Preferred  Securities,  primarily  because  (i) the
aggregate  principal  amount of the  Debentures  will be equal to the sum of the
aggregate  stated  liquidation  amount of the  Preferred  Securities  and Common
Securities;  (ii) the interest  rate and interest and other payment dates on the
Debentures will match the  Distribution  rate and Distribution and other payment
dates for the Preferred Securities; (iii) Hvide shall pay for all and any costs,
expenses  and  liabilities  of the Issuer  except the  Issuer's  obligations  to
holders of the Preferred  Securities under such Preferred  Securities;  and (iv)
the Declaration further provides that the Issuer will not engage in any activity
that is not consistent with the limited purposes of the Issuer.

         Notwithstanding  anything to the contrary in the  Indenture,  Hvide has
the right to set-off any  payment it is  otherwise  required to make  thereunder
with and to the extent Hvide has  theretofore  made, or is  concurrently  on the
date of such payment making, a payment under the Guarantee.

Enforcement Rights of Holders of Preferred Securities

         A holder of any Preferred  Securities may institute a legal  proceeding
directly  against Hvide to enforce its rights under the Guarantee  without first
instituting a legal proceeding against the Guarantee Trustee,  the Issuer or any
other person or entity.

         A default or event of default  under any Senior  Debt of Hvide will not
constitute  a default  under the  Indenture  or a  Debenture  Event of  Default.
However, in the event of payment defaults under, or acceleration of, Senior Debt
of Hvide, the subordination provisions of the Indenture provide that no payments
may be made in respect of the Debentures until such Senior Debt has been paid in
full or any payment default thereunder has been cured or waived. Failure to make
required  payments on the  Debentures  would  constitute  a  Debenture  Event of
Default.

Limited Purpose of Issuer

         The Preferred  Securities evidence a beneficial interest in the Issuer,
and the Issuer exists for the sole purpose of issuing the  Preferred  Securities
and Common  Securities and investing the proceeds  thereof in the Debentures.  A
principal  difference between the rights of a holder of Preferred Securities and
a holder of  Debentures  is that a holder of  Debentures  is entitled to receive
from Hvide the  principal  amount of and interest  accrued on  Debentures  held,
while a holder of Preferred Securities is entitled to receive

                                                        63

<PAGE>



Distributions from the Issuer (or from Hvide under the applicable  Guarantee) if
and to the  extent  the  Issuer  has funds  available  for the  payment  of such
Distributions.
   
Rights Upon Dissolution
    
   
         Upon any voluntary or involuntary dissolution,  winding-up, liquidation
or termination of the Issuer  involving the liquidation of the  Debentures,  the
holders  of  the  Preferred  Securities  will  be  entitled  to  receive,  after
satisfaction of liabilities to creditors of the Issuer as provided by applicable
law, out of assets held by the Issuer, the Liquidation Distribution in cash. See
"Description  of  the  Preferred   Securities--Liquidation   Distribution   Upon
Dissolution."  Upon any voluntary or  involuntary  liquidation  or bankruptcy of
Hvide,  the  Trustee,  as  holder  of the  Debentures,  would be a  subordinated
creditor  of Hvide,  subordinated  in right of payment to all Senior  Debt,  but
entitled  to  receive  payment  in full of  principal  and  interest  before any
stockholders  of Hvide  receive  payments or  distributions.  Since Hvide is the
guarantor under the Guarantee and has agreed to pay for all costs,  expenses and
liabilities of the Issuer (other than the Issuer's obligations to the holders of
the  Preferred  Securities),  the  positions  of  a  holder  of  such  Preferred
Securities and a holder of such  Debentures  relative to other  creditors and to
stockholders  of Hvide in the event of  liquidation or bankruptcy of Hvide would
be substantially the same.

                     DESCRIPTION OF CERTAIN INDEBTEDNESS

         The following is a description of the principal terms of certain of the
Company's indebtedness.

Credit Facility
   
         The Company  currently  has a credit  facility that provides for a $175
million  revolving  line of credit  (the  "Credit  Facility")  which  matures on
September 30, 2002 (the "Maturity Date"). There were no borrowings outstanding 
under the Credit Facility at June 30, 1997.
    
   
     Borrowings  under the Credit  Facility  bear  interest  based on one of two
calculations  set forth in the Credit  Agreement  dated  September 30, 1997 (the
"Credit  Agreement"),  at the  Company's  option,  plus a  margin  based  on the
Company's   compliance  with  certain  financial   ratios.   One  interest  rate
calculation  is tied to the  Eurodollar  (the  "Eurodollar  Rate") and the other
calculation is tied to the higher of the base rate of the  administrative  agent
named in the Credit  Agreement or the Federal  Funds  Effective  Rate (the "Base
Rate").  The Credit Agreement allows the Company to convert its revolving credit
loans from Eurodollar Rate loans to Base Rate loans,  and vice versa,  from time
to time. Such borrowings were accruing interest at approximately 6.7% at October
1, 1997. On the Maturity Date, all amounts  outstanding under the revolving line
of credit,  together with any and all accrued and unpaid  interest,  will become
due and  payable.  Prior  to the  Maturity  Date,  the  Company  can  repay  any
outstanding amount, in whole or in part, without penalty or premium.
    
   
    
   
         Covenants under the Credit  Facility,  among other things,  (i) require
the Company to meet certain  financial  tests,  including  tests  requiring  the
maintenance  of minimum  leverage  ratios,  debt service  coverage  ratios,  and
indebtedness to tangible net worth ratios; (ii) limit the creation or incurrence
of certain liens;  (iii) limit the incurrence of additional  indebtedness;  (iv)
restrict  the Company from making  certain  investments;  (v)  restrict  certain
payments,  including  dividends,  with respect to shares of any class of capital
stock; (vi) restrict  modification of the terms of the Preferred  Securities (as
defined herein),  and in certain  circumstances  the repayment,  redemption,  or
repurchase of the Preferred  Securities;  and (vii) limit certain corporate acts
of the Company, such as making certain dispositions of assets, and entering into
certain  types  of  business   transactions,   including   certain  mergers  and
acquisitions.
    
   
         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) an  acceleration  of the  maturity  of the
Preferred Securities or in certain  circumstances the prepayment,  redemption or
repurchase  of the  Preferred  Securities,  or any default  under the  Preferred
Securities, and (vii) a change in control.

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.

         In  connection  with the  acquisition  of the OMI Chemical  Carriers in
August 1996, 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.  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

                                                        66

<PAGE>



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 HVIDE 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  12,040,388
shares were issued and  outstanding  as of June 30,  1997,  5,000,000  shares of
Class B Common Stock,  par value $.001 per share, of which 3,181,936 shares were
issued and  outstanding as of June 30, 1997, and 10,000,000  shares of Preferred
Stock, par value $1.00 per share, none of which are issued and outstanding.

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.

         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

                                                        67

<PAGE>



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.

   
         The  Hvide  Family  and  the  Investor  Group  hold  51.5%  and  48.5%,
respectively,  of the outstanding Class B Common Stock. The Hvide Family and the
Investor  Group own 9.9% and 15.0%,  respectively,  of the  combined  classes of
Common Stock and each  controls  36.2% of the voting power and together  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 protect the Company's  ability to
operate its vessels in the U.S. domestic trade

                                                        68

<PAGE>



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; Possible Inability
to Convert Preferred Securities and Debentures."

         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

which  control is conferred  upon or permitted to be exercised by  Non-Citizens,
(e) whose  president or other chief  executive  officer or equivalent  position,

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
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

                                                        70

<PAGE>



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
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

                                                        71

<PAGE>



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.

         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 and the Investor Group, as the holders 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

                                                        72

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 up to three persons, respectively, to the
Company's  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  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. As of June 30, 1997, the Investor Group owned of record  1,409,999 shares
of Class B Common Stock  representing  48.5% of the  outstanding  Class B Common
Stock on such date.
    

         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.

Shareholders Agreement

         In  connection  with the September 30, 1994 issuance of debt and equity
securities to the Investor Group, 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.

   
    
         The  rights  granted  to the  Investor  Group  under  the  Shareholders
Agreement are in addition to the rights  granted to the Investor Group under the
Articles  of   Incorporation.   See   "--Certain   Provisions   of  Articles  of
Incorporation and Bylaws."

   
    
Registration Rights Agreement

         The Company and the Investor  Group have  entered  into a  registration
rights agreement.  Under such 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.

                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         The  following  is a summary of certain of the material  United  States
federal income tax  consequences  of the purchase,  ownership and disposition of
the Preferred Securities.  Unless otherwise stated, this summary deals only with
Preferred Securities held as capital assets by holders who purchase

                                                        75

<PAGE>



the Preferred  Securities upon original issuance.  It does not deal with special
classes  of holders  such as banks,  thrifts,  real  estate  investment  trusts,
regulated investment  companies,  insurance companies,  dealers in securities or
currencies,  tax-exempt investors,  foreign corporations and persons who are not
citizens or residents of the United States (except to the extent discussed under
the heading  "--Certain  United States Tax  Consequences  to  Non-United  States
Holders") or persons that will hold the Preferred  Securities as a position in a
"straddle,"  as  part  of a  "synthetic  security"  or  "hedge,"  as  part  of a
"conversion  transaction"  or other  integrated  investment,  or as other than a
capital  asset.  This  summary  also does not  address the tax  consequences  to
persons that have a functional currency other than the U.S. Dollar.  Further, it
does not include any description of any alternative  minimum tax consequences or
the tax laws of any state or local government or of any foreign  government that
may be  applicable  to the  Preferred  Securities.  This summary is based on the
Internal  Revenue Code of 1986,  as amended (the "Code"),  Treasury  regulations
thereunder and administrative and judicial  interpretations  thereof,  as of the
date  hereof,  all of which are  subject to change,  possibly  on a  retroactive
basis.

         INVESTORS  ARE ADVISED TO CONSULT  THEIR TAX  ADVISORS AS TO THE UNITED
STATES  FEDERAL  INCOME TAX  CONSEQUENCES  OF THE OWNERSHIP AND  DISPOSITION  OF
PREFERRED SECURITIES IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES,  AS WELL AS THE
EFFECT OF ANY STATE,  LOCAL,  FOREIGN OR OTHER TAX LAWS AND OF POTENTIAL CHANGES
IN APPLICABLE TAX LAWS.

Classification of the Debentures

         Hvide has taken the position that the Debentures will be classified for
United States federal income tax purposes as indebtedness of Hvide under current
law and, by acceptance of Preferred  Securities,  each holder covenants to treat
the Debentures as  indebtedness  and the Preferred  Securities as evidence of an
indirect  beneficial  ownership interest in the Debentures.  No assurance can be
given,  however,  that such  position  of Hvide  will not be  challenged  by the
Internal  Revenue Service ("IRS") or, if challenged,  that such a challenge will
not be successful.  The remainder of this discussion assumes that the Debentures
will be classified as indebtedness of Hvide for United States federal income tax
purposes.

Classification of the Issuer

         In connection with the issuance of the Preferred Securities, Dyer Ellis
& Joseph PC,  United  States tax counsel to the Issuer and Hvide,  rendered  its
opinion  generally to the effect that,  under then current law and assuming full
compliance  with the terms of the  Declaration  and the  Indenture  (and certain
other  documents),  based on certain  facts and  assumptions  contained  in such
opinion,  the Trust will be  classified  for United  States  federal  income tax
purposes as a grantor trust and not as an association  taxable as a corporation.
Accordingly,  for United  States  federal  income tax  purposes,  each holder of
Preferred  Securities  generally  will be  considered  the owner of an undivided
interest in the  Debentures,  and each holder will be required to include in its
gross income any original issue  discount  accrued with respect to its allocable
share of those Debentures.

Original Issue Discount

         Because  Hvide has the option,  under the terms of the  Debentures,  to
defer payments of interest by extending  interest  payment  periods for up to 60
months, all of the stated interest payments on the Debentures will be treated as
"original issue discount." Under the Code, holders of debt instruments

                                                        76

<PAGE>



(such as the  Debentures)  issued with original issue discount must include that
discount  in income on an  economic  accrual  basis  before the  receipt of cash
attributable  to the  interest,  regardless  of their method of tax  accounting.
Generally,  all of a  holder's  taxable  interest  income  with  respect  to the
Debentures will be accounted for as original issue discount. Actual payments and
distributions of stated interest will not,  however,  be separately  reported as
taxable  income.  The amount of  original  issue  discount  that  accrues in any
quarter will approximately  equal the amount of the interest that accrues on the
Debentures  in that quarter at the stated  interest  rate. In the event that the
interest  payment period is extended,  holders will continue to accrue  original
issue  discount in an amount  approximately  equal to the amount of the interest
payment due at the end of the extended  interest  payment  period on an economic
accrual basis over the length of the extended interest payment period.

         Because  income  on  the  Debentures  will  constitute  original  issue
discount,  corporate  holders  will  not  be  entitled  to a  dividends-received
deduction with respect to any income recognized with respect to the Debentures.

Redemption of Preferred Securities for Debentures or Cash Upon Liquidation of 
the Issuer

         Under  certain  circumstances,  the  Debentures  may be  discounted  to
holders in exchange for the  Preferred  Securities.  Under  current law,  such a
distribution to holders, for United States federal income tax purposes, would be
treated as a nontaxable  event to each holder,  and each holder would receive an
aggregate  tax  basis  in the  Debentures  distributed  equal  to such  holder's
aggregate tax basis in its Preferred  Securities  exchanged therefor. A holder's
holding  period in the  Debentures  so received  would include the period during
which the  Preferred  Securities  were held by such  holder.  If,  however,  the
exchange is caused by a Tax Event which  results in the Issuer being  treated as
an association taxable as a corporation the distribution would likely constitute
a taxable event to the Issuer and holders of the Preferred Securities.

         Under certain  circumstances  described herein (see "Description of the
Preferred Securities--Special Event Exchange or Redemption"), the Debentures may
be redeemed for cash and the proceeds of such redemption  distributed to holders
in  redemption  of  their  Preferred  Securities.  Under  current  law,  such  a
redemption  would,  for United States federal income tax purposes,  constitute a
taxable  disposition of the redeemed  Preferred  Securities,  and a holder would
recognize gain or loss in the same manner as if it sold such redeemed  Preferred
Securities for cash. See "--Sales of Preferred Securities."

Sales of Preferred Securities

         A holder that sells  Preferred  Securities  will recognize gain or loss
equal to the difference between the amount realized on the sale of the Preferred
Securities and the holder's adjusted tax basis in such Preferred  Securities.  A
holder's  adjusted tax basis in the Preferred  Securities  generally will be its
initial   purchase  price  increased  by  original  issue  discount   previously
includible  in  such  holder's  gross  income  to the  date of  disposition  and
decreased  by  payments  received  on the  Preferred  Securities  to the date of
disposition.  In general,  such gain or loss will be a capital  gain or loss and
will be a long-term  capital gain or loss if the Preferred  Securities have been
held for more than one year at the time of sale.

         The Preferred  Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid  interest with respect to the underlying
Debentures.  A holder who  disposes  of or  converts  his  Preferred  Securities
between record dates for payments of  distributions  thereon will be required to
include

                                                        77

<PAGE>



accrued but unpaid interest on the Debenture  through the date of disposition or
conversion in income as ordinary income,  and to add such amount to his adjusted
tax basis in his pro rata share of the underlying  Debentures deemed disposed of
or converted. To the extent the selling price is less than the holder's adjusted
tax basis (which basis will include, in the form of original issue discount, all
accrued but unpaid interest), a holder will recognize a capital loss. Subject to
certain limited exceptions,  capital losses cannot be applied to offset ordinary
income for United States federal income tax purposes.

Market Discount and Bond Premium

         Holders  that  purchase  the  Preferred  Securities  at a price that is
greater or less than the  adjusted  issue price of such  holder's  proportionate
share of the Debentures (which generally should approximate the face amount plus
accrued  but  unpaid  interest  on the  Debentures)  may be  considered  to have
acquired their  undivided  interests in the Debentures  with market  discount or
acquisition premium as such phrases are defined for United States federal income
tax  purposes.  Such holders are advised to consult their tax advisors as to the
income tax  consequences  of the  acquisition,  ownership and disposition of the
Preferred Securities.

Conversion of Preferred Securities Into Hvide Class A Common Stock

         Except  possibly  to the  extent  attributable  to  accrued  and unpaid
interest on the Debentures,  a holder of Preferred Securities will not recognize
income, gain or loss upon the conversion of the Preferred  Securities into Hvide
Class A Common  Stock  through  the  Conversion  Agent.  A holder  of  Preferred
Securities will,  however,  recognize gain upon the receipt of cash in lieu of a
fractional  share of Hvide  Class A Common  Stock  equal to the  amount  of cash
received less such holder's tax basis in such fractional  share. Such a holder's
tax basis in the Hvide Class A Common  Stock  received  upon  conversion  should
generally  be equal to such  holder's  tax  basis  in the  Preferred  Securities
delivered to the Conversion  Agent for exchange less the basis  allocated to any
fractional  share for which cash is received and such holder's holding period in
the Hvide Class A Common Stock received upon conversion  should  generally begin
on the date such holder  acquired  the  Preferred  Securities  delivered  to the
Conversion Agent for exchange.

         Holders of Preferred  Securities should not recognize gain or loss upon
expiration  of the  conversion  rights.  Such  expiration  should  not  affect a
significant  modification  of the  underlying  Debentures  within the meaning of
applicable  Treasury  Regulations,  and thus  will not be  considered  a sale or
exchange for purposes of federal income taxation.

Adjustment of Conversion Price

         Treasury  Regulations  promulgated  under Section 305 of the Code would
treat  holders  of  Preferred  Securities  as  having  received  a  constructive
distribution from Hvide in the event the conversion ratio of the Debentures were
adjusted  if (i) as a result  of such  adjustment,  the  proportionate  interest
(measured  by the  quantum of Hvide  Class A Common  Stock into or for which the
Debentures  are  convertible  or  exchangeable)  of the holders of the Preferred
Securities  in the assets or earnings and profits of Hvide were  increased,  and
(ii)  the  adjustment  was  not  made  pursuant  to  a  bona  fide,   reasonable
antidilution  formula.  An  adjustment  in the  conversion  ratio  would  not be
considered  made  pursuant  to such a  formula  if the  adjustment  was  made to
compensate for certain taxable  distributions  with respect to the Hvide Class A
Common Stock. Thus, under certain  circumstances,  a reduction in the conversion
price for the holders

                                                        78

<PAGE>



may result in deemed  dividend income to holders to the extent of the current or
accumulated  earnings and profits of Hvide.  Holders of the Preferred Securities
would be  required to include  their  allocable  share of such  deemed  dividend
income in gross income but would not receive any cash related thereto.

Information Reporting to Holders

         The Issuer  will  report the  original  issue  discount,  if any,  that
accrued during the year with respect to the  Debentures,  and any gross proceeds
received by the Issuer from the  retirement  or  redemption  of the  Debentures,
annually to the holders of record of the Preferred  Securities  and the IRS. The
Issuer  currently  intends to deliver such reports to holders of record prior to
January 31,  following each calendar  year. It is  anticipated  that persons who
hold  Preferred  Securities as nominees for  beneficial  holders will report the
required tax information to beneficial holders on Form 1099.

Backup Withholding

         Payments made on, and proceeds from the sale of,  Preferred  Securities
may be subject to a "backup"  withholding  tax of 31% unless the holder complies
with certain identification requirements. Any withheld amounts will generally be
allowed  as a credit  against  the  holder's  federal  income tax  provided  the
required information is timely filed with the IRS.

Possible Tax Legislation

         As a part of  President  Clinton's  Fiscal  1998 Budget  Proposal,  the
Treasury  Department proposed  legislation that, among other things,  would have
treated as equity for United  States  federal  income tax purposes  certain debt
instruments that are not shown as indebtedness on the consolidated balance sheet
of the Issuer.  Although this  proposal was not included in the tax  legislation
ultimately  enacted,  there can be no assurance that such a proposal will not be
enacted in the future,  that such future legislation will not have a retroactive
effective  date and that such future  legislation  will not  prevent  Hvide from
deducting interest on the Debentures. Such an event would constitute a Tax Event
and would permit the Issuer to exchange the Preferred Securities, in whole or in
part,  for the  Debentures  or  redeem,  in  whole  or in  part,  the  Preferred
Securities and Debentures.

Certain United States Tax Consequences to Non-United States Holders

         General. The following is a general discussion of certain United States
federal income and estate tax  consequences  of the  acquisition,  ownership and
disposition of Preferred Securities by a "Non-United States Holder" and does not
deal with tax  consequences  arising  under the laws of any foreign,  state,  or
local jurisdiction.  As used herein, a "Non-United States Holder" is a person or
entity that, for United States federal income tax purposes,  is not a citizen or
resident of the United  States,  a  corporation,  partnership,  or other  entity
created  or  organized  under  the  laws of the  United  States  or a  political
subdivision  thereof,  or an estate or trust,  the income of which is subject to
United  States  federal  income  taxation  regardless  of its  source,  or  that
otherwise is subject to United States federal income  taxation on a net basis in
respect of the  Preferred  Securities.  The tax  treatment of the holders of the
Preferred  Securities  may vary  depending  upon  their  particular  situations.
Certain  holders  (including  insurance  companies,  tax  exempt  organizations,
financial  institutions and  broker-dealers) may be subject to special rules not
discussed  below.  Prospective  investors who are Non-United  States Holders are
urged to consult  their tax advisors  regarding  the United  States  Federal tax
consequences of acquiring, holding and

                                                        79

<PAGE>



disposing of Preferred Securities and Hvide Class A Common Stock, as well as any
tax consequences that may arise under the laws of any foreign,  state,  local or
other taxing jurisdiction.

         Interest.  Interest  (including  original issue  discount)  received or
accrued  by a  Non-United  States  Holder of  Preferred  Securities  will not be
subject to United States federal  income or withholding  tax if such interest is
not  effectively  connected  with the conduct of a trade or business  within the
United States by such  Non-United  States Holder and (i) the  Non-United  States
Holder does not actually or  constructively  own 10% or more of the total voting
power of all voting stock of Hvide and is not a controlled  foreign  corporation
with respect to which Hvide is a "related person" within the meaning of the Code
and (ii) the  beneficial  owner of the  Preferred  Securities  certifies,  under
penalty of perjury,  that the beneficial owner is not a United States person and
provide the beneficial owner's name and address.

         Gain on Disposition of Preferred Securities. A Non-United States Holder
will  generally  not be  subject  to United  States  federal  income tax on gain
recognized on a sale,  redemption or other  disposition of a Preferred  Security
unless  (i) the gain is  effectively  connected  with the  conduct of a trade or
business  within the United States by the Non-United  States Holder,  or (ii) in
the case of a Non-United States Holder who is a nonresident alien individual and
holds the Preferred  Security as a capital asset,  such holder is present in the
United  States  for 183 or more  days in the  taxable  year  and  certain  other
requirements are met.

         Dividends on Hvide Class A Common  Stock.  In the event that  dividends
are  paid on  Hvide  Class A Common  Stock,  except  as  described  below,  such
dividends paid to a Non-United  States Holder of Hvide Class A Common Stock will
be subject to  withholding  of United States federal income tax at a 30% rate or
such lower rate as may be specified by an applicable  income tax treaty,  unless
the dividends are effectively  connected with the conduct of a trade or business
of the  Non-United  States Holder within the United  States.  If the dividend is
effectively  connected with the conduct of a trade or business of the Non-United
States Holder within the United States,  the dividend would be subject to United
States  federal  income  tax  on a net  income  basis  of  applicable  graduated
individual or corporate  rates and would be exempt from the 30%  withholding tax
described above. Any such effectively  connected dividends received by a foreign
corporation  may,  under  certain  circumstances,  be subject  to an  additional
"branch  profits tax" at a 30% rate or such lower rate as may be specified by an
applicable income tax treaty.

         Under current United States Treasury regulations,  dividends paid to an
address  outside the United States are presumed to be paid to a resident of such
country for purposes of the withholding  discussed above, and, under the current
interpretation   of  United  States  Treasury   regulations,   for  purposes  of
determining the applicability of a tax treaty rate. Under proposed United States
Treasury  regulations,  not currently in effect,  however,  a Non-United  States
Holder of Hvide  Class A Common  Stock who  wishes  to claim the  benefit  of an
applicable treaty rate would be required to satisfy applicable certification and
other requirements.  Certain  certification and disclosure  requirements must be
complied  with in order to be exempt  from  withholding  under  the  effectively
connected income exemption discussed above.

         A  Non-United  States  Holder  of Hvide  Class A Common  Stock  that is
eligible for a reduced rate of United States  withholding  tax pursuant to a tax
treaty may obtain a refund of any excess amounts currently withheld by filing an
appropriate claim for refund with the IRS.

     Gain on  Disposition  of Hvide Class A Common  Stock.  A Non-United  States
Holder  generally  will not be subject to United  States  income tax on any gain
recognized on a disposition of the Hvide Class

                                                        80

<PAGE>



A Common  Stock unless (i) Hvide is or has been a "United  States real  property
holding corporation" (a "USRPHC") within the meaning of Section 897(c)(2) of the
Code at any time  within the  shorter of the  five-year  period  preceding  such
disposition or such Non-United States Holder's holding period,  (ii) the gain is
effectively  connected with the conduct of a trade or business within the United
States of the NonUnited States Holder and, if a tax treaty applies, attributable
to a permanent  establishment  maintained by the Non-United States Holder, (iii)
The Non-United States Holder is an individual who holds the Hvide Class A Common
Stock as a capital  asset and is present  in the  United  States for 183 days or
more in the taxable year of the disposition and either (a) such individual has a
"tax home" (as defined for United  States  federal  income tax  purposes) in the
United States or (b) the gain is  attributable to an office or other fixed place
of business  maintained  in the United  States by such  individual,  or (iv) the
Non-United  States  Holder is subject  to tax  pursuant  to the Code  provisions
applicable to certain  United States  expatriates.  If an individual  Non-United
States Holder falls under clauses (ii) or (iv) above, he or she will be taxed on
his or her net gain derived from the sale under regular  United  States  federal
income tax rates. If the individual  Non-United States Holder falls under clause
(iii)  above,  he or she will be subject  to a flat 30% tax on the gain  derived
from  the  sale   which  may  be  offset  by  United   States   capital   losses
(notwithstanding  the fact that he or she is not  considered  a resident  of the
United  States).  If a Non-United  States  Holder that is a foreign  corporation
falls  under  clause  (ii)  above,  it will be taxed on its gain  under  regular
graduated  United States federal  income tax rates and, in addition,  will under
certain  circumstances  be subject to the branch profits tax equal to 30% of its
"effectively  connected earnings and profits" within the meaning of the Code for
the taxable year, as adjusted for certain items, unless it qualifies for a lower
rate under an applicable income tax treaty.

         A  corporation  is  generally a USRPHC if the fair amount  value of its
United  States real property  interests  equals or exceeds 50% of the sum of the
fair market value of its worldwide real property interests plus its other assets
used or held for use in a trade or business. Hvide believes that it currently is
not a USRPHC.

         Federal Estate Taxes.  A Preferred  Security  beneficially  owned by an
individual  who is a  NonUnited  States  Holder  at the time of his or her death
generally will not be subject to United States Federal estate tax as a result of
such individual's death,  provided that (i) such individual does not actually or
constructively own 10% or more of the total combined voting power of all classes
of stock of Hvide  entitled to vote within the meaning of section  871(h)(3)  of
the Code,  and (ii)  interest  payments  (including  payments of original  issue
discount) with respect to the Debentures would not have been, if received at the
time of such  individual's  death,  effectively  connected with the conduct of a
U.S.  trade or business by such  individual.  Common  Stock of Hvide  owned,  or
treated as owned, by an individual  Non-United  States Holder at the time of his
or her death will be included in such  holder's  gross estate for United  States
federal  estate tax purposes,  unless an applicable  estate tax treaty  provides
otherwise.

         Information  Reporting  and  Backup  Withholding.   Hvide  must  report
annually to the IRS and to each Non-United  States Holder the amount of interest
and  dividends  paid to such  holder and the amount of any tax  withheld.  These
information  reporting  requirements apply regardless of whether  withholding is
required.  Copies  of  the  information  returns  reporting  such  interest  and
dividends and  withholding  may also be made available to the tax authorities in
the country in which the  Non-United  States Holder resides under the provisions
of an applicable income tax treaty.

         In the case of  payments  of interest  to  Non-United  States  Holders,
temporary Treasury  regulations  provide that the 31% backup withholding tax and
certain information reporting will not apply to such

                                                        81

<PAGE>



payments with respect to which either the requisite certification,  as described
above,  has been  received  or an  exemption  has  otherwise  been  established;
provided that neither Hvide nor its payment agent has actual  knowledge that the
holder is a United States person or that the  conditions of any other  exemption
are  not  in  fact  satisfied.  Under  temporary  Treasury  regulations,   these
information  reporting and backup withholding  requirements will apply, however,
to the gross proceeds paid to a Non-United  States Holder on the  disposition of
the Preferred Securities by or through a United States office of a United States
or foreign  broker,  unless the holder  certifies to the broker under penalty of
perjury as to its name,  address  and  status as a foreign  person or the holder
otherwise establishes an exemption.  Information reporting requirements, but not
backup  withholding,  will  also  apply  to  a  payment  of  the  proceeds  of a
disposition  of the  Preferred  Securities  by or through a foreign  office of a
United States broker or foreign brokers with certain types of  relationships  to
the  United  States.   Neither  information  reporting  nor  backup  withholding
generally  will  apply to a payment  of the  proceeds  of a  disposition  of the
Preferred  Securities  by or  through a foreign  office or  foreign  broker  not
subject to the preceding sentence.

         United States backup  withholding  tax generally  will not apply to (a)
the  payment of  dividends  paid on Hvide Class A Common  Stock to a  Non-United
States Holder at an address  outside the United States or (b) the payment of the
proceeds  of the sale of Hvide  Class A Common  Stock to or through  the foreign
office of a broker.  In the case of the payment of proceeds  from such a sale of
Hvide Class A Common Stock through a foreign office of a broker that is a United
States person or a "U.S.  related person," however,  information  reporting (but
not backup  withholding)  is required  with  respect to the  payment  unless the
broker has  documentary  evidence  in its files  that the owner is a  Non-United
States Holder and certain  other  requirements  are met or the holder  otherwise
establishes an exemption.  For this purpose,  a "U.S.  related  person" is (i) a
controlled foreign corporation for United States federal income tax purposes, or
(ii) a foreign person 50% or more of whose gross income from all sources for the
three-year  period  ending  with the close of its  taxable  year  preceding  the
payment (or for such part of the period  that the broker has been in  existence)
is derived from activities that are effectively  connected with the conduct of a
United States trade or business.  The payment of the proceeds of a sale of Hvide
Class A Common Stock to or through a United States office of a broker is subject
to  information  reporting  and  possible  backup  withholding  unless the owner
certifies  its  non-United  States  status under penalty of perjury or otherwise
establishes an exemption.

         Backup withholding is not an additional tax. Any amounts withheld under
the backup  withholding rules may be refunded or credited against the Non-United
States  Holder's  United States federal income tax liability,  provided that the
required information is furnished to the IRS.

         These information and backup  withholding rules are under review by the
United States Treasury and their application to the Preferred Securities and the
Hvide Class A Common Stock could be changed by future regulations.  On April 15,
1996, the IRS issued proposed Treasury Regulations concerning the withholding of
tax and  reporting  for certain  amounts paid to  non-resident  individuals  and
foreign  corporations.  The proposed  regulations  would,  among other  changes,
eliminate the presumption  under current  regulations  with respect to dividends
paid to addresses outside the United States. The proposed Treasury  Regulations,
if adopted in their  present  form,  would be effective  for payments made after
December 31, 1997.  Prospective  purchasers of the Preferred  Securities  should
consult their tax advisors  concerning  the potential  adoption of such Treasury
Regulations.

                                PLAN OF DISTRIBUTION

         The  Offered  Securities  may be sold from  time to time to  purchasers
directly by the Selling  Holders.  Alternatively,  the Selling  Holders may from
time  to  time  offer  the  Offered  Securities  to  or  through   underwriters,
broker/dealers  or  agents,  who  may  receive   compensation  in  the  form  of
underwriting  discounts,  concessions or commissions from the Selling Holders or
the purchasers of such  securities for whom they may act as agents.  The Selling
Holders and any  underwriters,  broker/dealers or agents that participate in the
distribution of Offered Securities may be deemed to be "underwriters" within the
meaning of the Securities Act and any profit on the sale of such  securities and
any discounts,  commissions,  concessions or other compensation  received by any
such  underwriter,  broker/dealer  or agent  may be  deemed  to be  underwriting
discounts and commissions  under the Securities Act. The Offered  Securities may
be sold  from  time to time in one or more  transactions  at  fixed  prices,  at
prevailing  market prices at the time of sale, at varying  prices  determined at
the time of sale or at negotiated prices. The sale of the Offered Securities may
be effected in transactions  (which may involve  crosses or block  transactions)
(i) on any national  securities  exchange on which the Offered Securities may be
listed or quoted at the time of sale, (ii) in the over-the-counter market, (iii)
in  transactions  otherwise  than on such  exchanges or in the  over-the-counter
market,  or (iv) through the writing of options.  The Selling  Holders may enter
into hedging transactions with broker-dealers, which may in turn engage in short
sales of the  Offered  Securities  in the course of hedging the  positions  they
assume.  The Selling Holders may also sell Offered  Securities short and deliver
Offered Securities to close out such short positions,  or lend or pledge Offered
Securities to broker-dealers that may in turn sell such securities.  At the time
a  particular   offering  of  the  Offered  Securities  is  made,  a  Prospectus
Supplement,  if required, will be distributed setting forth the aggregate amount
and type of Offered  Securities  being  offered  and the terms of the  offering,
including the name or names of any underwriters,  broker/dealers or agents,  any
discounts,  commissions  and  other  terms  constituting  compensation  from the
Selling  Holders  and any  discounts,  commissions  or  concessions  allowed  or
reallowed or paid to broker/dealers.

   
         To  comply  with  the  securities  laws of  certain  jurisdictions,  if
applicable, the Offered Securities will be offered or sold in such jurisdictions
only through registered or licensed brokers or dealers. In addition,  in certain
jurisdictions the Offered Securities may not be offered or sold unless they have
been registered or qualified for sale in such jurisdictions or an exemption from
registration or qualification is available and is complied with.
    

         The Selling  Holders will be subject to  applicable  provisions  of the
Exchange Act and the rules and  regulations  thereunder,  which  provisions  may
limit the timing of purchases and sales of any of the Offered  Securities by the
Selling Holders. The foregoing may affect the marketability of such securities.

         The Company and the Trust will bear the expenses of registration of the
Offered Securities,  and the Selling Holders will pay all underwriting discounts
and selling commissions,  if any. The Selling Holders will be indemnified by the
Company and the Trust,  jointly and severally against certain civil liabilities,
including  certain  liabilities under the Securities Act, or will be entitled to
contribution  in  connection  therewith.  The  Company  and  the  Trust  will be
indemnified by the Selling Holders severally against certain civil  liabilities,
including  certain  liabilities under the Securities Act, or will be entitled to
contribution in connection therewith.

Item 15.  Indemnification of Directors and Officers

         The Company's Articles of Incorporation  provide 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

                                                       II-1

<PAGE>



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 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

                                                       II-2

<PAGE>



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 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;


                                                       II-3

(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;

(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

                                                       II-4

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  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)      The undersigned registrant hereby undertakes:

                  (a) To file,  during any  period in which  offers or sales are
         being made, a post-effective amendment to this registration statement:

                           (i) To include any material  information with respect
                  to the plan of  distribution  not previously  disclosed in the
                  registration   statement  or  any  material   change  to  such
                  information in the registration statement;

                  (b) That, for the purpose of determining  any liability  under
         the Securities Act of 1933, each such post-effective amendment shall be
         deemed to be a new  registration  statement  relating to the securities
         offered therein, and the offering of such securities at that time shall
         be deemed to be the initial bona fide offering thereof.

                  (c) To remove from  registration by means of a  post-effective
         amendment any of the securities  which remain unsold at the termination
         of the Offering.

         (2) The undersigned  registrant hereby undertakes that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  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.

         (3)  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.

         (4) 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.

Re:      Hvide Marine Incorporated and Hvide Capital Trust
         Registration Statement on Form S-3 (File No. 333-34941)

Ladies and Gentlemen:

We are delivering  this opinion in connection with the  Registration  Statement,
which relates to the  registration  of (i) 2,300,000 of the Trust's 6 1/2% Trust
Convertible  Preferred  Securities  (the  "Preferred  Securities"),  (ii) $115.0
million  aggregate   principal  amount  of  the  Company's  6  1/2%  Convertible
Subordinated  Debentures due June 15, 2012 (the "Debentures"),  (iii) the shares
of  Class A  Common  Stock of the  Company,  $0.001  par  value,  issuable  upon
conversion of the Preferred  Securities or the  Debentures and shares of Class A
Common Stock issued in connection  with the  acquisition of certain vessels (the
"Common Stock") and (iv) the Company's guarantee of the payment of distributions
by the Trust and payments on  liquidation  of the Trust or the redemption of the
Preferred  Securities  pursuant to a guarantee  agreement,  dated as of June 24,
1997,  between the Company and The Bank of New York,  as guaranty  trustee  (the
"Guarantee", and together with, the Preferred Securities, the Debentures and the
Common Stock, the "Registrable Securities").

Based upon and subject to the foregoing, we are of the opinion that:

1.       The shares of Common Sock have been duly authorized and, in the case of
         the Common Stock issuable upon  conversion of the Preferred  Securities
         or the Debentures,  upon conversion in accordance with the terms of the
         Indenture, will be validly issued, fully paid and nonassessable.

2.       The Debentures have been duly authorized by the Company, and constitute
         valid and binding  obligations of the Company,  enforceable against the
         Company in accordance with their terms.

3.       The Guarantee has been duly  authorized by the Company,  and is a valid
         and binding obligation of the Company,  enforceable against the Company
         in accordance with its terms.

The opinions rendered in paragraphs 2 and 3 above relating to the enforceability
of the  Debentures  and the Guarantee  are subject to the following  exceptions,
limitations  and  qualifications:  (i) the  effect  of  bankruptcy,  insolvency,
fraudulent transfer, fraudulent conveyance, reorganization,  moratorium or other
similar laws now or hereafter in effect  relating to or affecting the rights and
remedies  of  creditors;  and (ii) the effect of general  principles  of equity,
whether  enforcement  is  considered  in a proceeding  in equity or law, and the
discretion of the court before which any proceeding therefor may be brought.

To the extent that the  obligations  of the Company  under the  Indenture may be
dependent  upon such  matters,  we assume for  purposes of this opinion that the
Indenture Trustee is duly organized, validly existing and in good standing under
the laws of its jurisdiction of organization; that the Indenture Trustee is duly
qualified to engage in the activities  contemplated  by the Indenture;  that the
Indenture  has been duly  authorized,  executed and  delivered by the  Indenture
Trustee and constitutes the legally valid, binding and enforceable obligation of
the Indenture  Trustee  enforceable  against the Indenture Trustee in accordance
with its terms; that the Indenture Trustee is in compliance,  generally and with
respect to acting as a trustee under the Indenture, with all applicable laws and
regulations; and that the Indenture Trustee has the requisite organizational and
legal power and authority to perform its obligations under the Indenture.

We hereby  consent  to the  filing of this  opinion  with the  Commission  as an
exhibit to the  Registration  Statement and the reference to this firm under the
heading "Legal Matters" in the Registration Statement.

Very truly yours,



Dyer Ellis & Joseph

Re:      Hvide Capital Trust

Ladies and Gentlemen:

         We have acted as special  Delaware  counsel to Hvide Capital  Trust,  a
Delaware  statutory  business  trust (the "Trust"),  in connection  with certain
matters  relating to the  creation of the Trust and the issuance by the Trust of
Preferred Securities.  The Preferred Securities have been issued pursuant to (i)
a Purchase  Agreement dated June 23, 1997 (the "Purchase  Agreement")  among the
several purchasers named on Schedule I thereto (the "Purchasers"), the Trust and
the Company and (ii) the Amended and Restated  Declaration of Trust of the Trust
dated as of June 27, 1997 (the "Governing  Instrument").  We understand that the
Trust is in the process of registering  the Preferred  Securities  pursuant to a
Registration  Statement (and the Prospectus  forming a part thereof) on Form S-3
to be filed with the Securities and Exchange  Commission (the  "Commission")  by
the Trust and Hvide Marine  Incorporated  (the  "Company")  on or about the date
hereof (the  "Registration  Statement").  Capitalized  terms used herein and not
otherwise herein defined are used as defined in the Governing Instrument.

         In rendering  this opinion,  we have examined and relied upon copies of
the following documents in the forms provided to us: the Certificate of Trust of
the  Trust as filed in the  Office  of the  Secretary  of State of the  State of
Delaware  (the  "State  Office")  on  June  20,  1997  (the  "Certificate");   a
Declaration  of Trust of the  Trust  dated as of June 20,  1997  (the  "Original
Governing Instrument"); the Governing Instrument; the Indenture dated as of June
27, 1997 between the Company and The Bank of New York, as Trustee; the


<PAGE>



Guarantee Agreement by the Company dated as of June 27, 1997; the Purchase Agree
ment;  the  Trust's  Offering  Memorandum  dated June 24,  1997  relating to the
Preferred  Securities  (the  "Offering  Memorandum");  the  Registration  Rights
Agreement  dated June 27, 1997 among the Trust,  the Company and the Purchasers;
the  Registration  Statement;  and a certification of good standing of the Trust
obtained as of a recent date from the State  Office.  In such  examinations,  we
have assumed the  genuineness  of all  signatures,  the  conformity  to original
documents  of all  documents  submitted  to us as  drafts  or copies or forms of
documents to be executed and the legal  capacity of natural  persons to complete
the  execution  of  documents.  We have  further  assumed  for  purposes of this
opinion:  (i) the due  formation  or  organization,  valid  existence  and  good
standing  of each  entity  (other  than the Trust) that is a party to any of the
documents  reviewed by us under the laws of the  jurisdiction  of its respective
formation or organization;  (ii) the due authori zation,  execution and delivery
by,  or on  behalf  of,  each of the  parties  thereto  of the  above-referenced
documents (including,  without limitation, the due authorization,  execution and
delivery of the Governing  Instrument  and the Purchase  Agreement  prior to the
first  issuance  of  Preferred  Securities);  (iii)  that no event has  occurred
subsequent to the filing of the  Certificate  that would cause a dissolution  or
liquidation  of  the  Trust  under  the  Original  Governing  Instrument  or the
Governing Instrument, as applicable;  (iv) that the activities of the Trust have
been and will be conducted in accordance with the Original Governing  Instrument
or the Governing Instrument, as applicable, and the Delaware Business Trust Act,
12 Del. C. ss.ss.  3801 et seq. (the  "Delaware  Act");  (v) that each Holder of
Preferred Securities has made payment of the required consideration therefor and
received  a  Preferred  Securities   Certificate  in  consideration  thereof  in
accordance  with the terms  and  conditions  of the  Governing  Instrument,  the
Offering  Memorandum  and  the  Purchase  Agreement;  (vi)  that  the  Preferred
Securities  have  been  issued  and sold to,  and held or  transferred  by,  the
Preferred  Securities  Holders  (and any  subsequent  transferee),  and that all
transfers have been made, in accordance with the terms, conditions, requirements
and procedures set forth in the Governing  Instrument,  the Offering  Memorandum
and the Purchase Agreement; (vii) that none of the Preferred Securities has been
called for  redemption,  redeemed,  converted or canceled  (except in connection
with  a  permitted  transfer)  and  all  of  the  Preferred   Securities  remain
outstanding;  and (viii) that the documents examined by us are in full force and
effect,  express the entire understanding of the parties thereto with respect to
the subject matter thereof and have not been amended,  supplemented or otherwise
modified,  except as herein referenced.  No opinion is expressed with respect to
the requirements of, or compliance with, federal or state securities or blue sky
laws. We have not participated in the preparation of the Registration  Statement
or any other offering  materials  relating to the Preferred  Securities,  and we
assume no  responsibility  for their  contents.  As to any fact  material to our
opinion,   other  than  those  assumed,   we  have  relied  without  independent
investigation  on the  above-referenced  documents and  certificates  and on the
accuracy, as of the date hereof, of the matters therein contained.

         Based on and subject to the  foregoing,  and limited in all respects to
matters of Delaware law, it is our opinion that:

         1. The Trust is a duly created and validly existing  statutory business
trust in good standing under the laws of the State of Delaware.



<PAGE>



         2. The Preferred  Securities  constitute validly issued and, subject to
the  qualifications set forth in paragraph 3 below, fully paid and nonassessable
beneficial interests in the assets of the Trust.

         3. Under the  Delaware Act and the terms of the  Governing  Instrument,
each Preferred Security Holder of the Trust, in such capacity,  will be entitled
to the same limitation of personal liability as that extended to stockholders of
private  corporations for profit organized under the General  Corporation Law of
the State of Delaware;  provided, however, we express no opinion with respect to
the liability of any Preferred Security Holder who is, was or may become a named
Trustee of the Trust.  We note that the Holders of Preferred  Securities  may be
obligated to make  payments or provide  indemnity or security and will be liable
for the debts and  obligations  of the Trust to the extent  provided  and as set
forth in the Governing Instrument.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration  Statement  and to the use of our name  under  the  heading  "LEGAL
MATTERS" in the Prospectus forming a part thereof. In giving this consent, we do
not thereby  admit that we come within the category of persons  whose consent is
required under Section 7 of the Securities Act of 1933, as amended, or the rules
and regulations of the Commission thereunder. This opinion speaks only as of the
date hereof and is based on our  understandings  and  assumptions  as to present
facts, and on our review of the  above-referenced  documents and the application
of Delaware  law as the same exist as of the date  hereof,  and we  undertake no
obligation  to update or  supplement  this opinion after the date hereof for the
benefit of any person or entity with respect to any facts or circumstances  that
may  hereafter  come to our  attention  or any  changes in facts or law that may
hereafter occur or take effect.

                                    Very truly yours,

                                    MORRIS, NICHOLS, ARSHT & TUNNELL



                                                                 Exhibit 8.1
