         mailed to the passenger's home), SEAVISION agrees to keep such
         information in confidence and not to sell, exchange or otherwise
         provide such information to any other party without the prior written

         SEAVISION may use to perform its obligations hereunder, or which
         otherwise may be in SEAVISION's control.

     f)  Unseaworthy Condition.  SEAVISION shall not knowingly create an

         off-loading, at the regularly scheduled port or port(s), as SEAVISION
         may select, and that it will, in no way, inhibit or hamper SEAVISION's
         right to take possession of the goods, equipment and wares and remove
         the same from the Vessel, provided that all sums due RCCL or the Vessel
         have been paid or placed in escrow or a bond for said amount is

     c)  Independent Contractor and Waiver of Maritime Lien.  SEAVISION
         --------------------------------------------------            
         understands that it is not the agent of RCCL but is an independent
         contractor and has no right to pledge the credit of RCCL or any Vessel
         in any manner or sum whatsoever. SEAVISION shall not contract with any
         supplier of merchandise unless the supplier executes a purchase order
         containing a conspicuous notice to the effect that SEAVISION has no
         right or authority to bind any Vessel or create a lien upon them and
         that by acceptance of such purchase order, the supplier acknowledges
         that he/she looks solely to SEAVISION and not the Vessel for payment of
         goods ordered. Neither SEAVISION nor SEAVISION's Operator shall have
         the right to assert maritime liens on any Vessel for any payments due

         or any other applicable law. In the event that a lien is placed on any
         Vessel in contradiction of the terms hereof or as a result of any act,
         omission or neglect by SEAVISION or its employees, SEAVISION shall
         remove immediately, by bond or otherwise, any such lien or reimburse
         RCCL for the cost incurred by RCCL in obtaining its removal. Neither
         this Concession Agreement nor the relationship of the parties hereby

         each Vessel.  For this purpose, SEAVISION's Operator will sign on
         Ship's Articles and obey the Master's Rules and Regulations.  The
         foregoing will not in any way detract from or modify SEAVISION's
         status as an independent contractor or its employer-employee
         relationship with its personnel, and its right to control its
         employees as described herein.

         employee of SEAVISION to be removed with the employee's belongings from

         Underwriters which shall provide coverage to RCCL and SEAVISION. In the
         event that SEAVISION or its employees cause any loss or damage covered

         on the vessel.  In addition, RCCL will permit SEAVISION to use the
         shoreside medical facilities with which RCCL has provider agreements
         for medical care for SEAVISION's employees who are working on RCCL's
         vessels; provided, however, if SEAVISION elects to use such shoreside

         shall name RCCL as an additional named insured and shall provide that
         the insurance may not be canceled or modified without at least thirty
         (30) days prior written notice to RCCL.  [Redacted - confidential

         limitations shall not apply to damages resulting from the gross
         negligence or willful misconduct or SEAVISION, its employees or
         agents.  The warranties expressly set out in this Agreement are

         between the parties relative to concessions on the Vessels and all
         prior negotiations, agreements and communications shall be merged
         herein and superseded hereby.

     b)  Amendments.  The terms of this Agreement may not be waived, altered,
         ----------                                                          
         modified, amended or supplemented in any manner whatsoever except by a
         written document duly executed by both parties hereto.

     c)  Assignments.  Neither party may assign this Agreement, in whole or in
         -----------                                                          
         part, without the prior written consent of the other party.

         The foregoing is not intended to apply to a sale of the stock of
         either company or a merger or consolidation which results in a change
         of ownership of the company.

     d)  Press Releases.  The parties shall consult with each other and issue a
         --------------

         after the execution hereof.  During the term of this Agreement, RCCL

         breach or rights or remedies provided hereunder and no course of
         dealing shall be deemed a continuing waiver of the same inaccuracy,
         breach or any other right or remedy, unless such waiver is in writing
         and is signed by the party sought to be bound.  The failure of a party
         to exercise any right or remedy shall not be deemed a waiver of such
         right or remedy in the future.

     f)  Modification and Severability.  If a court of competent jurisdiction
         -----------------------------                                       
         declares that any provision of this Agreement is illegal, invalid or
         unenforceable, then such provision shall be modified automatically to
         the extent necessary to make such provision fully legal, valid or
         enforceable, and this Agreement otherwise shall remain in full force
         and effect.

                                      -16-
