          WHEREAS, the Sellers collectively own all of the issued and
outstanding capital stock of DSS (the "DSS Shares");

          WHEREAS, DSI is engaged, directly and/or indirectly through
wholly-owned subsidiaries, in the ownership and operation of dry bulk carriers
and has entered, directly and/or indirectly through wholly-owned subsidiaries,
into vessel management agreements with DSS (the "Management Agreements")
pursuant to which DSS provides technical and commercial vessel management to DSI

          WHEREAS, pursuant to the Option Agreement DSI has granted the Sellers

business day following closing of DSI's initial public offering on March 23,
2005 and terminating on the first anniversary thereof, subject to the terms and
condition set forth in the Option Agreement, to sell to DSI all, but not less
than all, of the DSS Shares;

          WHEREAS, pursuant to the terms of the Option Agreement, the Sellers'
have agreed to provide to DSI certain audited financial information of DSS for
DSS's fiscal years ending December 31, 2004 and December 31, 2005, respectively,

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants set forth herein and for other good and valuable consideration, the
receipt and sufficiency of which are acknowledged hereby, the parties hereto
hereby agree as follows:

Amendment
---------

1.   Section 2.1 of the Option Agreement is hereby amended to read in its
     entirety as follows:

          Sellers' Put Option. (a) DSI hereby grants to the Sellers, jointly and
          not severally, an irrevocable option (the "Put Option") to cause DSI
          (or a wholly owned subsidiary of DSI to be designated by DSI) to
          purchase from the Sellers all, but not less than all, of the DSS
          Shares for the aggregate purchase price of $20 million (the "Purchase
          Price"). The Put Option shall commence on the first business day
          following the closing of the IPO and shall terminate on April 1, 2006
          (the "Put Option Termination Date").

2.   Section 2.2 of the Option Agreement is hereby amended to read in its
     entirety as follows:

          Exercise of Put Option.(b) The Put Option shall be exercised by the
          Sellers' delivery to DSI of a written notice no later than three (3)
          business days prior to the Put Option Termination Date of the Sellers'
          intent to cause DSI (or its designee) to purchase all, but not less
          than all, of the DSS Shares (the "Put Option Notice"). Upon the
          exercise of the Put Option, DSI (or its designee) shall purchase, and
          the Sellers shall sell on a date selected by DSI (the "Put Option
          Closing Date"), the DSS Shares, free and clear of any Liens, not more
          than 60 days following receipt by DSI of the Put Option Notice, at
          which time the Purchase Price shall be transferred to an account or
          accounts designated by the Sellers and the certificates for the DSS
          Shares shall be delivered to DSI, together with such instruments of
          transfer as are necessary to vest title to the DSS Shares in DSI.

3.   Section 3.1 of the Option Agreement is hereby amended to read in its
     entirety as follows:

          DSI's Call Option.(c) (a) The Sellers hereby grant to DSI (or its
          designee) an irrevocable option (the "Call Option") to purchase all,
          but not less than all, of the DSS Shares for the Purchase Price. The
          Call Option shall commence on April 3, 2006 and shall terminate on the
          second anniversary of the IPO (the "Call Option Termination Date").

Waiver
------

4.   In accordance with Section 6.5 of the Option Agreement, each of the parties
     hereto hereby agrees to irrevocably waive the Sellers' obligation to
     provide audited balance sheets, related statements of income and retained
     earnings and changes in financial positions of DSS for DSS' fiscal years
     ending December 31, 2004 and December 31, 2005. Nothing contained in this
     Amendment shall be deemed to relieve the Sellers' of their obligations
     pursuant to Section 6.2 of the Option Agreement to cooperate with DSI in
     causing DSS to prepare certain interim financial data as of the Put Option
     Closing Date.

Miscellaneous
-------------

5.   Except as expressly amended and modified by this Amendment, all provisions
     of the Option Agreement shall remain in full force and effect.

6.   Capitalized terms used herein and not otherwise defined shall have the
     meanings set forth in the Option Agreement.

7.   This Amendment shall become effective upon the execution of this Amendment
     by all of the parties hereto.

8.   This Amendment may be executed in one or more counterparts, each of which
     shall be deemed an original but all of which taken together shall
     constitute one and the same agreement.

     IN WITNESS WHEREOF, the parties have signed this Amendment as of the date
first set forth above.
