          executive personnel may travel from time to time on the Vessels as
          needed to insure the performance by SEAVISION of its obligations

          (except for port charges, gratuities and personal items), passenger-
          type accommodations for such executive personnel, unless all

                                      -2-
<PAGE>
 
          passenger facilities have been utilized by paying passengers.  Such
          executive personnel shall travel alone on a space available basis and
          not with their families or other guests and shall be bound by and
          subject to all the terms and conditions of RCCL's passenger ticket
          contract.

     c)  Marketing.  RCCL hereby agrees to provide reasonable marketing support

          hereby agrees to work with SEAVISION's marketing personnel to develop
          appropriate and effective means for testing and gauging passenger
          reaction to the System on a regular basis.  RCCL shall from time to
          time, provide access to the Vessels while in their home port for
          SEAVISION personnel and guests to demonstrate the System to potential
          advertisers, marketers and clients.  Such visits shall be requested in
          advance and RCCL reserves the right to refuse to allow such visitors

          similar means) with respect to each passenger onboard the Vessel:
          name, cabin assignment, dining assignment and folio number.  In the
          event SEAVISION acquires any additional passenger information such as
          addresses and phone numbers as a result of the passenger's use of the
          System (e.g. through the purchase of items to be 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 consent of
          RCCL.  Without limiting the foregoing, SEAVISION shall not sell any
          lists of RCCL passenger names or use such names in any manner other
          than as may be required to fulfill its obligations under this
          Agreement.  In the event SEAVISION is required to provide the
          information to a fulfillment house to process orders, SEAVISION shall
          use commercially reasonable efforts to ensure that such information is
          kept confidential by such fulfillment house.

          power as to personnel other than SEAVISION's employees on board the
          Vessel and RCCL agrees that the Vessel, through its

     a)  Health and Moral Character.  SEAVISION shall only employ persons who
         --------------------------                                          
          are in good health, sober and of good moral character.  Each of
          SEAVISION's Operators must hold a doctor's health report on a form
          approved by RCCL indicating that the employee is medically fit for
          service on board the Vessel in accordance with standards established
          by RCCL and which are the same as for RCCL's own employees.  It shall
          be SEAVISION's sole responsibility to employ persons who have valid
          passports, visas and all other permits required by any governmental
          authority whether United States or foreign in order that they might
          enter and leave the ports of call of the Vessel.

     b)  SEAVISION Employees.  SEAVISION's Operators are solely the employees of
         -------------------                                                    
          SEAVISION and shall, under no circumstances, be deemed employees of
          RCCL.  SEAVISION is solely responsible for the payment of all wages,
          vacation pay, commissions, benefits and repatriation expenses of each
          of its employees.  SEAVISION shall comply with all applicable laws,
          governmental regulations or other governmental requirements relating
          to wages, tax withholding and benefits paid to employees and governing
          SEAVISION's conduct in connection therewith.

     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 to them and SEAVISION, on behalf of itself and
          its employees, hereby waives any rights that SEAVISION or its
          employees may have to assert claims against RCCL under the Jones Act,
          U.S. Code Section 688 et seq, or any other applicable law.  In the
          event that a lien is placed on any Vessel in contradiction

                                      -7-
<PAGE>
 
          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 created
          constitutes a partnership or a joint venture.

     d)  Picket Lines.  SEAVISION shall immediately take all lawful action, at
         ------------                                                         
          its sole expense, to effect removal of any picket line or other
          impediment to a Vessel's sailing resulting from any labor dispute
          between SEAVISION and its employees or subcontractors.

     e)  Agent.  SEAVISION irrevocably appoints the Master and Vessel's Hotel
         -----                                                               
          Manager as its agent, with the power of overall supervision of
          SEAVISION's Operator for purposes of health, safety and discipline of
          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.

     f)  Repatriation.  In the Master's discretion, and for purposes of health,
         ------------                                                          
          safety and discipline, the Master of any Vessel may require any
          employee of SEAVISION to be removed with the employee's belongings
          from the Vessel at any time when the Vessel is in port.  If for any
          reason any of SEAVISION's Operator is unable to be on board a Vessel
          upon its scheduled departure from any port, SEAVISION shall be
          responsible for the repatriation of said party, and SEAVISION shall be
          fully responsible for any and all fines, penalties, and assessments
          levied by any third party in connection with any violation of the
          immigration laws of any government, nation, or country.

     g)  Prohibited Acts.  SEAVISION's Operator are not permitted:
         ---------------                                          

          i)  To carry or consume on board any Vessel any narcotic or other
               drug which is prohibited, or for which a doctor's prescription
               would be required, except pursuant to a program of medical care
               under the direct supervision of the Vessel's doctor;

          ii)  To board the Vessel in an intoxicated state or to consume
               alcoholic beverages aboard the Vessel to the point of
               intoxication or to the point where during the subsequent
               performance of their duties such consumption could become
               apparent to the passengers;

          iii)  To engage in any form of gambling aboard the Vessel; and

                                      -8-

          iv)  To sell any merchandise to passengers or crew members except in
               the course of their duties and only during the agreed hours of
               operation of SEAVISION's Concession thereunder.

13.  Insurance.
     --------- 

     a)  Marine Hull and Machinery.  RCCL agrees that the Vessel's owners shall,
         -------------------------                                              
          at their own expense, provide and maintain marine hull and machinery
          and war risk hull and machinery insurance covering the Vessel, with
          first class marine underwriters, which insurance shall be endorsed to
          designate the owners as the sole loss payee.  In the event that
          SEAVISION or its employees cause any loss or damage covered by this
          insurance, or which would have been covered by this insurance but for
          any deductible, SEAVISION agrees to reimburse owners for the
          deductible applicable to such loss or damage; provided however,
          SEAVISION's obligation to reimburse shall not exceed [Redacted -
          confidential treatment requested].  While SEAVISION will not be named
          in this insurance as an additional assured, neither the owners nor the
          underwriters shall have any further right of recovery or subrogation
          in excess of said deductible against SEAVISION on account of any loss
          or any damage covered by such insurance.

     b)  Protection and Indemnity.  RCCL shall, at its own expense, obtain and
         ------------------------                                             
          maintain protection and indemnity insurance with first-class Marine
          Underwriters which shall provide coverage to RCCL and SEAVISION.  In
          the event that SEAVISION or its employees cause any loss or damage
          covered by this insurance, or which would have been covered by this
          insurance but for any deductible, SEAVISION agrees to reimburse owners
          for the deductible applicable to such loss or damage; provided however
          such reimbursement shall not exceed [Redacted - confidential treatment
          requested].

     c)  Medical.  RCCL shall provide, at no charge to SEAVISION, the use of its
         -------                                                                
          shipboard medical facilities for employees of SEAVISION while working
          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
          facilities, SEAVISION shall reimburse RCCL for all expenses associated
          with such medical care.

     d)  SEAVISION's Insurance.  SEAVISION shall maintain general liability
         ---------------------                                             
          insurance, in form and content acceptable to RCCL.  Such insurance
          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
          treatment requested]

                                      -9-
<PAGE>
 
     e)   Limitation of Liability.  Except as expressly provided elsewhere in
          -----------------------                                            
          this Agreement, no party shall be liable for any indirect, special or
          consequential damages arising out of this Agreement.  SEAVISION's
          liability shall not exceed [Redacted - confidential treatment
          requested] in the aggregate, provided however, that the foregoing
          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
          exclusive and are in lieu of all other warranties, express or implied,
          including without limitation the implied warranty of merchantability
          and fitness for a particular purpose or any implied warranties arising
          from course of performance, course of dealing or usage of trade.

     in its sole discretion and without liability to SEAVISION, may change the
     itineraries of the Vessels.  [Redacted - confidential treatment requested]

15.  Force Majeure.  RCCL shall not be liable to SEAVISION for any cruise
     -------------                                                       
     delays, cancellations or deviations, or any loss or damage to SEAVISION's
     property, caused by acts outside the reasonable control of RCCL, including
     Acts of God, acts of war, public enemies, government restrictions, perils
     of the sea, mechanical difficulties, seizure or arrest of the Vessel, or
     acts of passengers or other third parties.

16.  Indemnification.

     a)  SEAVISION.  SEAVISION shall indemnify and hold harmless RCCL, the
         ---------                                                        
          Vessels' owners, the successors and assigns of the foregoing, and
          their respective officers, directors, employees and agents from and
          against all damages, liabilities, claims and expenses (including
          attorneys' fees and payments for deductibles under any insurance
          policies) arising from or based upon SEAVISION's operations, or any
          act, omission or neglect by SEAVISION or its employees or agents.

          and expenses (including attorneys' fees and payments for deductibles
          under any insurance policies) arising from or based upon RCCL's
          operations or any act, omission or neglect by RCCL or its employees or
          agents.

17.  Default.

     a)  Termination Upon Default.  Either party may terminate this
         ------------------------

                after receipt by the breaching party of written notice thereof
                from the other party; provided, however, if such breach is as a
                result of software errors or malfunctions, the cure period shall
                be [redacted-confidential treatment requested] from receipt of
                written notice and Seavision shall provide RCCL with a written
                plan and timetable to remedy such software problem within

     accordance with the laws of Florida to the exclusion of all choice-of-law
     rules which might otherwise be applicable except to the extent that

     safety or to mandatory requirements imposed by the laws of the state of the
     Vessel's registry.  Venue for all matters hereunder shall be in the courts

     to hold in confidence and not disclose to any third party, except to
     authorized persons in the course of its work for RCCL, any and all
     information or data of a confidential nature not generally available to the

     notified of such agreements) and understands that its obligations under
     this confidentiality provision shall continue after the expiration of this
     Agreement and until RCCL specifically releases such obligations in writing.

     Except as permission may be specifically granted to RCCL in writing and in
     accordance with SEAVISION's rules, RCCL agrees to hold in confidence and

     acknowledges that, except as expressly provided for in this Agreement, RCCL
     possesses no title to or ownership of any System or any portion thereof.

     Agreement.

     Each party acknowledges that its violation of its confidentiality or non-
     disclosure obligations under this Agreement may cause irreparable damage to
     the other that cannot be fully remedied by money damages.  Accordingly, in
     the event of any such violation or threatened violation, the injured party
     will be entitled, in addition to pursuing any other remedy available to it
     under this Agreement or at law, to obtain injunctive or other

                                      -12-

          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

          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
         --------------

          installed (or is planned to be installed) and in which interactive
          television services are discussed.

          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
