                                 DIVIDEND POLICY

     The Board has not declared  dividends to this date. OMI's current policy is
not  to pay  dividends,  but to  retain  cash  for  use  in  its  business.  Any
determination to pay dividends by OMI in the future will be at the discretion of
the Board of  Directors  and will  depend  upon  OMI's  results  of  operations,
financial condition,  capital  restrictions,  covenants and other factors deemed
relevant by the Board of Directors. Payment of dividends is limited by the terms
of certain agreements to which OMI and its subsidiaries are party.

                              SELLING STOCKHOLDERS

                              PLAN OF DISTRIBUTION

     The Company has not been advised by the Selling Stockholders as to any plan
of distribution.  Distribution of the Common Stock by the Selling  Stockholders,
or by pledgees,  donees  (including  charitable  organizations),  transferees or
other  successors in interest,  may be effected from time to time in one or more
transactions (which may involve block transactions):

          (i) on the NYSE in transactions that may include special offerings and
     exchange distributions pursuant to and in accordance with the rules of such
     exchange,

          (ii) in the over-the-counter market, or

          (iii)  in  transactions  otherwise  than  on such  exchange  or in the
     over-the-counter market, or in a combination of any such transactions.

     Such  transactions  may be effected by the Selling  Stockholders  at market
prices  prevailing  at the time of sale,  at prices  related to such  prevailing
market prices, at negotiated prices or at fixed prices. The Selling Stockholders
may  effect  such  transactions  by  selling  the  Common  Stock  to or  through
broker-dealers,  and such broker-dealers may receive compensation in the form of
discounts  or  commissions  from  the  Selling   Stockholders  and  may  receive
commissions  from the  purchasers  of the Common  Stock for whom they may act as
agent.  The Selling  Stockholders  may agree to indemnify any  broker-dealer  or
agent that  participates in  transactions  involving sales of the shares against
certain liabilities, including liabilities arising under the Securities Act.

     The validity of the Common Stock being  offered  hereby will be passed upon

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS OF OMI

     Marshall  Islands law provides that with respect to legal actions against a
person by reason of the fact that such person is or was a director or officer of
a corporation,  such  corporation (i) must indemnify such person for expenses of
litigation when such person is successful on the merits; (ii) may indemnify such
person  for  expenses,  judgments,  fines  and  amounts  paid in  settlement  of
litigation (other than in an action by or in right of the corporation),  even if
such person is not successful on the merits,  if such person acted in good faith
and in a manner that such person reasonably  believed to be in or not opposed to
the best interests of the corporation (and, in the case of criminal proceedings,
had no reason to believe that  conduct was  unlawful);  and (iii) may  indemnify
such person for the expenses of a suit by or in the interest of the corporation,
even if such person is not  successful  on the merits,  if such person  acted in
good faith and in a manner which such person reasonably believed to be in or not
opposed  to  the  best   interests  of  the   corporation,   provided   that  no
indemnification  may be made if such  person  has  been  found to be  liable  of
negligence  or misconduct in the  performance  of his duties to the  corporation
unless the court in which such action was brought  determines that,  despite the
finding of liability, such person is fairly and reasonably entitled to indemnity
for such  expenses.  The  advancement  of  litigation  expenses to a director or
officer  is also  authorized  upon  receipt  by the  board  of  directors  of an
undertaking  to repay such  amounts  if it is  ultimately  determined  that such
person is not entitled to  indemnification.  The OMI Articles and By-laws  limit
personal  liability of directors and officers to the fullest extent permitted by
Marshall Islands law.

     Insofar  as  indemnification  for  liabilities  arising  under the  federal
securities laws may be permitted to directors,  officers or persons  controlling
OMI pursuant to the  foregoing  provisions,  OMI has been  informed  that in the
opinion of the  Securities  and  Exchange  Commission  such  indemnification  is
against public policy and therefore unenforceable.

ITEM 17. UNDERTAKINGS.

(a)  The undersigned registrant hereby undertakes:

     (1) To file,  during any period in which  offers or sales are being made of
the  securities   registered   hereby,  a   post-effective   amendment  to  this
registration statement;

          (i) To include  any  prospectus  required  by Section  10(a)(3) of the
     Securities Act of 1933;

          (ii) To reflect in the  prospectus  any facts or events  arising after
     the  effective  date of the  registration  statement  (or the  most  recent
     post-effective amendment thereof) which,  individually or in the aggregate,
     represent  a  fundamental  change  in the  information  set  forth  in this
     registration  statement.  Notwithstanding  the  foregoing,  any increase or
     decrease  in volume of  securities  offered (if the total  dollar  value of
     securities  offered  would not exceed  that which was  registered)  and any
     deviation from the low or high end of the estimated  maximum offering range
     may be  reflected  in the form of  prospectus  filed  with  the  Commission
     pursuant  to Rule  424(b) if, in the  aggregate,  the changes in volume and
     price  represent no more than a 20 percent change in the maximum  aggregate
     offering price set forth in the "Calculation of Registration  Fee" table in
     this registration statement; and

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

provided,  however,  that the  undertakings set forth in paragraphs (i) and (ii)
above  do  not  apply  if  the   information   required  to  be  included  in  a
post-effective  amendment by those  paragraphs is contained in periodic  reports
filed with or furnished to the Commission by the registrant  pursuant to Section
13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in this registration statement.

     (2) 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  herein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (b) 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  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.

     (c) 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 Securities 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.

     (d) The undersigned registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information  omitted from the form of prospectus filed as part
     of this registration  statement in reliance upon Rule 430A and contained in
     a 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 this
     registration statement as of the time it was effective.

          (2) 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 initial bona fide offering thereof.
