     1.  Responsibilities.
         ---------------- 

      (a) Subject to the terms and conditions hereof, SeaVision hereby agrees
to:

          (i)    Provide, for each Ship designated by NCL (including without
                 limitation the Initial Ship) at no charge to NCL, an
                 interactive television system (the "System") consisting of the
                 hardware and software described or listed on Exhibit A attached
                 hereto (collectively, the "System Hardware and Software") and,
                 in connection therewith, provide the services (the "Services")
                 set forth on Exhibit B attached hereto. In addition thereto,
                 SeaVision shall provide for, and install on, the S/S Norway new
                 in-cabin televisions which the parties acknowledge will cost
                 SeaVision approximately [Redacted - confidential treatment
                 requested] including installation costs. Until such time as
                 SeaVision shall have received the aggregate amount of
                 [Redacted -confidential treatment requested] under subsection
                 3(a) herein, SeaVision shall retain title to all such
                 televisions. Upon SeaVision's receipt of such aggregate amount
                 thereunder, title to such televisions shall transfer to and
                 vest in NCL, free and clear of any liens, claims or
                 encumbrances arising by or through SeaVision. NCL hereby
                 acknowledges and agrees that the System Hardware and certain of
                 the interactive modules of the Software are installed on the
                 Initial Ship and, as of the date of this Agreement, the
                 Hardware and such installed modules of the Software are
                 performing satisfactorily. Notwithstanding anything contained
                 herein or in any other provision of this Agreement that might
                 be construed to the contrary (except for the foregoing
                 provisions regarding ownership of televisions on the S/S
                 Norway), SeaVision shall at all times retain title to all
                 components of the System, including all System Hardware and
                 Software or other hardware or software hereafter installed by
                 Sea Vision on any Ship hereunder.

          (ii)   Provide all personnel reasonably necessary and appropriate to
                 operate the System and provide the Services. One (1) SeaVision
                 technician (the "Manager") will remain on-board each Ship on
                 which the System is then installed and operating to operate the
                 System on an on-going basis and to fulfill the responsibilities
                 of the on-board television coordinator (as described on Exhibit
                 C attached hereto) for so long as this Agreement shall be in
                 effect with respect to that Ship. SeaVision hereby acknowledges
                 that the Manager shall at all times be an employee of
                 SeaVision. NCL hereby agrees to serve as SeaVision's paying
                 agent for payment, at the direction of SeaVision, of all
                 salary, payroll taxes and fringe benefits costs in connection
                 with the Manager; provided that SeaVision promptly reimburses
                 NCL for all such costs

                                      -2-
<PAGE>
 
                 incurred by NCL. SeaVision understands that, while on-board any
                 Ship, its personnel will be subject to the authority of the
                 Master of that Ship and the officer(s) designated to oversee
                 the operation of the System and the Services. SeaVision agrees
                 that its employees will be considered seamen and will attend
                 and participate in boat drills held onboard each of the
                 respective Ships as requested by the Ship's master and
                 officers. All such employees shall attend Coast Guard
                 inspections and, if required by NCL, will earn life boat
                 efficiency certificates. SeaVision shall employ onboard the
                 Ships only those persons medically fit for service onboard the
                 vessels in accordance with standards established by NCL and who
                 have agreed to abide by the orders of the masters and officers
                 for service onboard the Ships. It shall be the sole
                 responsibility of SeaVision to absorb and pay the costs of pre-
                 employment physical examinations and to employ persons who have
                 valid passports, visas and all other permits required by any
                 governmental authority in order that they might enter and leave
                 the ports of call of the Ship on which they are employed.
                 Annual physicals shall be required of SeaVision's shipboard
                 employees.

          (iii)  Upgrade the hardware and/or software used in the System, at no
                 cost to NCL, at such times and in such manner as is reasonably
                 necessary or appropriate, to maintain the System on the Ship,
                 subject always, in the case of hardware upgrades only, to the
                 consent of NCL, which consent shall not unreasonably be
                 withheld, and to the constraints placed thereon by the space
                 available on-board any Ship for the installation of such
                 hardware.

      (b) Subject to the terms and conditions hereof, NCL hereby agrees to:

          (i)    Make available to SeaVision in respect of any Ship upon which
                 the System is then installed or is then to be installed (a)
                 that Ship to the extent necessary for SeaVision's operation and
                 maintenance of the System, including but not limited to
                 granting SeaVision personnel unlimited access to the television
                 studio and video distribution system on board that Ship, (b)
                 such personnel as are reasonably necessary or appropriate to
                 support SeaVision's successful operation and maintenance of the
                 System, including but not limited to appropriate on-board
                 support for and oversight of the operation and maintenance of
                 the System by a designated officer on that Ship, provided,
                 however, that (i) SeaVision shall at all times be primarily
                 responsible for the operation and maintenance of the System,
                 and (ii) NCL shall not be obligated hereunder to make available
                 NCL's personnel if and to the extent that the result thereof
                 would be the interference with that personnel's ability to
                 perform his or her other employment duties owing to NCL, (c)
                 all necessary systems integration support to allow the System
                 to communicate with NCL's on-board systems, and (d) appropriate

                                      -3-
<PAGE>
 
                 accommodations on-board that Ship for SeaVision personnel who
                 are engaged in operating or maintaining the System on the Ship,
                 which accommodations shall be comparable to those
                 accommodations provided by NCL to its cruise staff of similar
                 rank, such as the Ship's systems manager, casino manager or
                 shore excursion manager. It is understood that SeaVision
                 personnel occupying such accommodations will, at all times
                 while on-board such Ship, be subject to NCL's policies
                 regarding on-board contractors, including those concerning
                 dress, decorum and personal behavior.

          (ii)   Furnish accommodations on-board each Ship upon which the System
                 is then installed and otherwise respond favorably to reasonable
                 requests by SeaVision's management for accommodations on-board
                 such Ship, on mutually-agreeable dates and subject to
                 availability, to allow SeaVision senior personnel to monitor
                 the on-going performance of the System and SeaVision's
                 personnel and for the purpose of determining whether
                 enhancements and improvements to the System should be
                 recommended. Requests for such accommodations shall not exceed
                 one (1) cabin/voyage per month per Ship. NCL shall also provide
                 the Manager with all other perquisites that it provides to its
                 employees of similar rank.

          (iii)  Provide marketing support for the System on-board each Ship on
                 which the System is then installed, which support shall be
                 consistent with the type and level of such support being
                 provided by NCL as of the date hereof on-board the Initial
                 Ship. In addition thereto, the parties shall engage in such
                 other activities of a supporting nature as are acceptable to
                 both parties to this Agreement, and upon terms acceptable to
                 both parties to this Agreement.

          (iv)   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. Such means
                 shall include but not be limited to on-board questionnaires,
                 on-board focus groups, one-on-one passenger interviews and
                 post-cruise questionnaires. SeaVision shall retain the right to
                 designate the individuals who will conduct these activities,
                 subject to the approval of such individuals by NCL. If
                 SeaVision marketing personnel are not available (or cannot
                 reasonably be accommodated) on a Ship, the Manager on that Ship
                 may assume these responsibilities.

          (v)    Provide access to each Ship when such Ship is in port, for
                 SeaVision personnel to demonstrate the System to potential
                 advertisers, marketers and clients. In connection with making
                 such demonstrations, SeaVision

                                      -4-
<PAGE>
 
                 shall conform to NCL's procedures for approving on-board
                 visitors, including but not limited to making advance requests
                 for boarding passes.

          (vi)   Use commercially reasonable efforts to cause its on-board
                 concessionaires to work with SeaVision to develop mutually
                 beneficial applications for the System.

          (vii)  Provide the Manager with the following data, if available, in
                 electronic form (i.e., diskettes, tapes or other similar means)
                 with respect to each passenger on-board any Ship on which the
                 System is then installed: name, home address and telephone
                 number, age, cabin assignment, dining assignment and on-board
                 account number.

          (viii) Collect all monies paid or payable by passengers in respect of
                 Services provided on or through the System and charged to the
                 respective on-board account of such passengers.

          (ix)   Provide without change limited and reasonable on-board medical
                 care as needed for minor illnesses and injuries to the extent
                 such treatment can be provided on-board the Ship. NCL shall not
                 be responsible hereunder for on-shore continuing or follow-up
                 treatment.

     2.   Term/Extension to Other Ships.
          ----------------------------- 

      (a) Unless sooner terminated in accordance with the terms of this
          Agreement, the term of this Agreement (the "Term") shall commence on
          the date first written above and shall expire on the fifth anniversary
          thereof (the "Expiration Date").

      (b) NCL hereby grants to SeaVision the exclusive right, for the Term of
          this Agreement, to install, operate and maintain all in-cabin
          interactive television systems and any kiosk-based interactive
          television systems connected to such in-cabin systems on the M/S
          Dreamward and the S/S Norway.

      (c) (i)    If, during the term of this Agreement, NCL wishes to install or
                 have installed interactive television and video entertainment
                 services on-board any ship owned or operated by NCL other than
                 the M/S Dreamward and the S/S Norway, NCL shall, in each such
                 instance, have the right to solicit third-party offers to
                 provide such services, but shall be required, in each instance,
                 to first notify SeaVision, in writing, of its intent to do so.

          (ii)   If, in respect of any ship, NCL receives from any third-party
                 an offer to provide onboard that ship interactive television
                 and video entertainment services during the term of this
                 Agreement, NCL shall promptly notify

                                      -5-
<PAGE>
 
                 SeaVision thereof and shall disclose to SeaVision the terms of
                 such third-party offer. SeaVision shall thereafter have a
                 period of thirty (30) days to match such third party offer with
                 its own offer to provide the System on such ship. If SeaVision
                 matches such third party offer under substantially the same
                 terms and conditions and in all material respects, NCL shall
                 thereafter be precluded from accepting such third party offer.
                 If SeaVision fails to match such third party offer as provided
                 herein, NCL may, in sole discretion, accept such third party
                 offer.

          (iii)  NCL and SeaVision each understands and agrees that the other
                 party is not required hereunder to agree to any particular
                 contractual arrangement or proposal regarding the installation
                 of the System on any additional ship, including without
                 limitation any such proposal that is similar or identical to
                 the arrangement hereunder in respect of the M/S Dreamward or
                 the S/S Norway. Subject to the foregoing provisions of this
                 Section 2(c), in the event the parties agree that SeaVision
                 will install, operate and maintain the System on any additional
                 Ship(s), the references herein made to a or any Ship and/or the
                 System shall be deemed to include such other Ship(s) and the
                 System(s) installed thereon, which such modifications as are
                 reasonably necessary and appropriate to reflect the
                 individualized System(s) installed on each such Ship and are
                 consistent with the agreement of the parties in respect
                 thereto.

     3.   Revenue-Sharing and Payment Terms.
          --------------------------------- 

      (a) In consideration of SeaVision's agreement to provide televisions on
          the S/S Norway, SeaVision shall be entitled to receive [Redacted -
          confidential treatment requested] of the first [Redacted -
          confidential treatment requested] of the Adjusted Gross Revenues (as
          defined below) generated by all of the Systems installed onboard the
          Ships.  If SeaVision has not received under this subsection 3(a) the
          aggregate amount of [Redacted - confidential treatment requested] on
          or before the second anniversary of the date of this Agreement, NCL
          shall pay to SeaVision on such second anniversary date an amount equal
          to [Redacted - confidential treatment requested] less the aggregate
          amount theretofore received by SeaVision under this section 3(a),
          whereupon SeaVision shall not be entitled to receive any further funds
          under this subsection 3(a).

      (b) If the aggregate of all of the Adjusted Gross Revenues generated by
          all of the Systems installed on-board the Ships, from the commencement
          of this Agreement, is less than the amount (hereinafter referred to as
          the "Investment Recovery") obtained by multiplying the number of Ships
          on which a System is then installed by [Redacted - confidential
          treatment requested], then NCL shall be entitled to retain [Redacted -
          confidential treatment requested] of the Adjusted Gross

                                      -6-
<PAGE>
 
          Revenues for the applicable calendar month, as indicated on the
          applicable report provided to NCL by SeaVision pursuant to the terms
          of subsection 3(e) below, and shall promptly remit the remaining
          [Redacted -confidential treatment requested] of such Adjusted Gross
          Revenues to SeaVision in accordance with this Section 3. (For purposes
          of this subsection 3(b), the relevant Adjusted Gross Revenues are the
          cumulative Adjusted Gross Revenues from the date of this Agreement to
          the relevant month-ending date of such calculation; such Adjusted
          Gross Revenue calculation is not performed on an annual basis.)
                                       ---                               

      (c) If the aggregate of all of the Adjusted Gross Revenues generated by
          all the Systems on board the Ships, from the commencement of this
          Agreement, equals or exceeds the Investment Recovery, then, for the
          twelve month period commencing on the date Investment Recovery is most
          recently achieved and for each succeeding twelve month period (subject
          always to any reversion to the allocation set forth in subsection 3(b)
          caused by the installation of the System on an additional Ship) the
          Adjusted Gross Revenues generated by all of the Systems installed
          onboard the Ships shall be allocated between the parties as follows:

          (i)    NCL shall be entitled to retain [Redacted - confidential
                 treatment requested] of, and shall pay over to SeaVision the
                 remaining [Redacted - confidential treatment requested] of the
                 first [Redacted -confidential treatment requested] of such
                 Adjusted Gross Revenues;

          (ii)   NCL shall be entitled to retain [Redacted - confidential
                 treatment requested] of, and shall pay over to SeaVision the
                 remaining [Redacted - confidential treatment requested] of,
                 such Adjusted Gross Revenues from [Redacted - confidential
                 treatment requested] through [Redacted - confidential treatment
                 requested]; and

          (iii)  NCL shall be entitled to retain [Redacted - confidential
                 treatment requested] of, and shall pay over to SeaVision the
                 remaining [Redacted - confidential treatment requested] of,
                 such Adjusted Gross Revenues in excess of [Redacted -
                 confidential treatment requested].

      (d) "Adjusted Gross Revenues", for purposes of this Agreement, shall mean
          the aggregate of all amounts paid to NCL in connection with
          passengers' use of the Services provided by or on the System and
          charged to such passengers' respective on-board accounts by NCL, other
          than amounts paid or payable in respect of shore excursions, room
          service orders and wine orders purchased or made on the System, the
          revenues from which shall be retained exclusively by NCL, less (i)(A)
          the cost to SeaVision of goods sold in the case of products and
          services sold on the System, (B) the cost to SeaVision of pay-per-view
          programming provided on the System, and (C) the commissions paid by
          SeaVision to third parties for

                                      -7-

          advertising sold on the System, the aggregate amount of which NCL
          shall pay over to SeaVision, and (ii) credits paid by NCL to
          passengers in the case of gaming on the System.

      (e) On or before the twenty-first day of each calendar month during the
          Term of this Agreement, SeaVision shall provide NCL with a written
          report detailing the Adjusted Gross Revenues generated by the System
          on each Ship on which the System is then installed from cruises
          completed during the prior calendar month.  This report shall govern
          the determination of fees to be retained by NCL and the revenues to be
          remitted by NCL to SeaVision under the terms of this Agreement.
          SeaVision shall provide any and all hardware and/or software
          reasonably necessary or appropriate to interface SeaVision's
          accounting software with the Ship's property management system in
          order for SeaVision to obtain accurate accounting information for such
          reports.

      (f) Within ten (10) days after NCL's receipt of any monthly report
          delivered to NCL by SeaVision pursuant to the terms of subsection 3(e)
          herein, NCL shall remit to SeaVision all Adjusted Gross Revenues
          generated by the System on the Ship during the calendar month
          applicable to such report, less its share of such Adjusted Gross
          Revenues as provided in this Section 3.

      (g) NCL shall promptly notify SeaVision of any changes, adjustments or
          chargebacks (relative to the Adjusted Gross Revenues in respect of any
          calendar month) of which NCL receives notice after it has made a
          remittance to SeaVision in respect of such calendar month, and
          together therewith, provide to SeaVision appropriate documentation
          supporting all such changes, adjustments or chargebacks.  In the event
          properly-supported changes, adjustments or chargebacks result in a
          reduction of the Adjusted Gross Revenues generated in respect of such
          calendar month, SeaVision shall, within thirty (30) days after its
          receipt of the applicable notice and supporting documentation, refund
          to NCL SeaVision's percentage of the aggregate of such changes,
          adjustments or chargebacks.

     4.   Confidentiality.
          --------------- 

      (a) NCL acknowledges that the System represents and will continue to
          represent the valuable, confidential and proprietary property of
          SeaVision.  SeaVision is not by this Agreement conveying to NCL any
          exclusive proprietary or ownership rights in the System, including,
          but not limited, to any patent, copyright, trademark, service mark,
          trade secret, trade name or other intellectual property rights, except
          that NCL will have the limited rights expressly set forth in this
          Agreement.  Accordingly, NCL acknowledges that, except as expressly
          provided for in this Agreement, NCL possesses no title to or ownership
          of any System or any portion

                                      -8-
<PAGE>
 
          thereof. NCL will keep the System free and clear of all claims, liens
          and encumbrances resulting from actions or omissions of NCL.

      (b) Each party agrees, during the Term of this Agreement and thereafter,
          to maintain the confidential nature of the terms and conditions of
          this Agreement and of any proprietary information shared by the other
          with it.  In the case of SeaVision's proprietary information, such
          proprietary information shall include, but is not limited to (i) any
          knowledge gained by NCL of SeaVision's proprietary application
          software or the configuration of the System; (ii) SeaVision's
          marketing and sales materials; (iii) the format of any and all
          SeaVision reports, including those for data management, revenue
          remittance and marketing surveys, to the extent protected by copyright
          law; and (iv) SeaVision's marketing and advertising client list.  In
          the case of NCL's proprietary information, such proprietary
          information shall include, but is not limited to, the data provided by
          NCL to SeaVision pursuant to the terms of subsection 1(b)(vii) hereof,
          except for any such data in respect of; any passenger who purchases
          merchandise from SeaVision through the System, which data shall not be
          NCL's proprietary information.  Notwithstanding anything contained in
          this Agreement to the contrary, the terms of this Section 4(b) shall
          survive the expiration or termination of this Agreement.

      (c) 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 equitable relief from any court of
          competent jurisdiction as may be necessary or appropriate to prevent
          any further violations thereof.

      (d) Each party agrees to notify the other immediately upon the notifying
          party's becoming aware of or reasonably suspecting the possession, use
          or knowledge of all or part of any of the other party's proprietary
          information by any person or entity not authorized by this Agreement
          to have such possession, use or knowledge. The notifying party will
          promptly furnish the other party with details of such possession, use
          or knowledge, will assist in preventing a recurrence thereof and will
          cooperate with the other party in protecting the other party's rights
          in the other party's proprietary information. A party's compliance
          with the terms of this Section 4 will not be construed as any waiver
          of the other party's right to recover damages or obtain other relief
          against the notifying party for the notifying party's breach of its
          confidentiality or non-disclosure obligations under this Agreement or
          the negligent or intentional harm to the other party's proprietary
          rights.

     5.   Termination.
          ----------- 

                                      -9-
<PAGE>
 
      (a) NCL shall have the right to terminate this Agreement prior to the
          Expiration Date in the event the System fails to achieve the technical
          performance standards set forth in Exhibit D attached hereto.  NCL may
          not exercise this right (i) if such technical failure occurs as a
          result of NCL's failure to perform any or all of its obligations under
          the terms of this Agreement; and (ii) without written notice to
          SeaVision of its intention to do so and prior to a period of 90 days
          following such notice in which SeaVision may effect a cure of such
          failure.  In respect of any notice hereunder by NCL of its intention
          to terminate this Agreement as a result of any System deficiency which
          served as the basis for any prior such termination notice, NCL shall
          be obligated, in the case of the second such notice, to extend to
          SeaVision a thirty-day cure period rather than a ninety-day cure
          period and NCL shall not be obligated, in the case of the third or any
          subsequent notice, to extend to SeaVision any cure period whatsoever.
          SeaVision shall, within fifteen (15) days following NCL's written
          notice to SeaVision under such clause (iii), above, provide to NCL
          SeaVision's written response regarding such failure, which response
          shall set forth SeaVision's assessment of the cause of such failure
          and SeaVision's plan to rectify such failure.  In any event, SeaVision
          shall make a good faith effort to rectify such failure as promptly as
          is reasonable under the circumstances and, where appropriate, will
          implement temporary "work around" solutions until a permanent solution
          can be implemented.

      (b) SeaVision shall have the right to terminate this Agreement in whole or
          in part prior to the Expiration Date in the event the System fails to
          achieve the financial performance standards that SeaVision shall
          determine are necessary to warrant its investment in the System.  In
          the event SeaVision intends to terminate this Agreement pursuant to
          this subsection 5(b), it shall do so in writing to NCL no less than
          one hundred twenty (120) days prior to ceasing operations hereunder or
          thereon, as the case may be.

      (c) Either party hereto shall have the right to terminate this Agreement
          immediately upon written notice to the other party upon such party
          being declared insolvent or bankrupt, or making an assignment for the
          benefit of creditors, or in the event that a receiver is appointed, or
          any proceeding for appointment of a receiver or to adjudge such party
          a bankrupt, or to take advantage of the insolvency laws is demanded
          by, for, or against such party under any provision under the laws of
          any state or country.

      (d) NCL shall have the right to terminate this Agreement prior to the
          Expiration Date in the event SeaVision defaults in the performance of
          any covenant, warranty or agreement made herein (except a failure by
          the System to achieve certain technical performance standards which is
          governed by subsection 5(a) herein), and such default has not been
          cured within thirty (30) days after receipt of written notice thereof
          given by NCL to SeaVision.

                                      -10-

      (e) SeaVision shall have the right to terminate this Agreement prior to
          the Expiration Date in the event NCL defaults in the performance of
          any covenant, warranty or agreement made herein and such default has
          not been cured within thirty (30) days after receipt of written notice
          thereof given by SeaVision to NCL.

      (f) Notwithstanding the termination or expiration of this Agreement as
          provided for in this Section 5 and elsewhere in this Agreement, NCL
          shall continue to owe, and shall promptly pay to SeaVision in
          accordance with the terms of Section 3 hereof, all amounts set forth
          in Section 3 that shall have accrued on and prior to the date of such
          termination or expiration.

      (g) As soon as is practicable after the expiration or any termination of
          all or part of this Agreement or any renewal operating term thereof,
          SeaVision shall remove the System, including all hardware and
          software, and all on-board SeaVision personnel from the Ship.  The
          parties hereby agree and acknowledge that in accordance with Section 1
          hereof, SeaVision will retain title to any and all hardware and
          software installed on board the Ship by SeaVision (x) at all times
          while this Agreement or any renewal operating term thereof is in
          effect as well as (y) in the event SeaVision chooses not to continue
          operating the System installed thereon.  Notwithstanding the
          foregoing, if SeaVision elects to terminate this Agreement for any of
          the reasons set forth above, NCL shall have the right to (i) purchase
          all SeaVision hardware (but not software) installed by SeaVision on
          any Ship, including but not limited to televisions at an aggregate
          purchase price equal to the greater of (A) [Redacted - confidential
          treatment requested] less the aggregate Adjusted Gross Revenues
          theretofore paid to SeaVision in accordance with Section 3 herein in
          respect of that Ship and (B) SeaVision's then unamortized cost for
          such hardware and (ii) obtain a nontransferable license to use (but
          only on the applicable Ship) the SeaVision software installed by
          SeaVision on that Ship for an annual license fee of [Redacted -
          confidential treatment requested] which annual fee shall include
          routine software maintenance provided by SeaVision.

     6.   Right to Inspect Books & Records.  SeaVision and NCL shall keep full
          --------------------------------                                    
and accurate accounts, records, books, journals, ledgers and data (collectively,
"Records") with respect to the business done by each party respectively under
this Agreement, which Records shall at all times show truthfully, accurately and
fully the compliance by each party with its respective obligations under this
Agreement.  Each party shall have the right, through its designated
representatives, at all reasonable times, upon reasonable advance notice, to
inspect the Records of the other as necessary to verify the sales, revenues
generated and fees collected pursuant to this Agreement.  The parties shall
retain all Records at all times during the Term of this Agreement and any and
all extensions or renewals thereof, and for at least three (3) years thereafter,
and shall make the Records available to the other party during regular business
hours, wherever the Records are maintained, within ten (10) days after receipt
of demand for inspection from such

                                      -11-
<PAGE>
 
other party. Both parties shall maintain the confidential nature of any Records
so inspected pursuant to and in accordance with the provisions of Section 4
hereof.

     7.   Insurance/Waiver of Subrogation.
          ------------------------------- 

      (a) So long as their respective insurers so permit, neither party hereto
          shall be liable to the other, or to the insurer of the other, claiming
          by way of subrogation through or under such other party with respect
          to any loss or damage, in whole or in part, to the System on any Ship,
          to the extent that such other party shall be reimbursed out of that
          party's insurance coverage carried for such other party's protection
          with respect to such loss or damage.  If so permitted, the parties
          shall each obtain any special endorsements required by their
          respective insurance carriers to evidence compliance with the waiver
          and release set forth herein and shall provide a copy thereof to the
          other party.

      (b) SeaVision hereby warrants, represents and covenants that, consistently
          during the Term and at its sole expense, each Manager and each member
          of SeaVision's System installation crews shall be included on
          SeaVision's protection and indemnity cover and shall be covered by
          general medical insurance maintained by SeaVision, in each case for
          such periods of time as the Manager or such crew member is posted to a
          Ship.

     8.   Interruption in Performance.  Neither NCL nor SeaVision shall be
          ---------------------------                                     
liable to the other for any loss, damage or loss of profits arising out of any
interruption or cessation of the Services to be provided hereunder when such
interruption or cessation is caused by any circumstance beyond the reasonable
control of such party.

     9.   Indemnification.
          --------------- 

      (a) SeaVision shall indemnify, defend and hold harmless NCL and its
          successors and assigns from and against any and all liabilities,
          claims, suits, damages, judgments, awards, penalties, losses and other
          liabilities (including all related reasonable attorneys' fees, costs
          and expenses in connection therewith) (collectively referred to
          hereinafter as "Losses") suffered or incurred by NCL by reason of,
          arising out of or in connection with (i) any negligent, willful or
          intentional act or omission of SeaVision (or an employee, agent or
          representative of SeaVision) committed or omitted, as the case may be,
          in the course of SeaVision's performance of the terms of this
          Agreement or (ii) SeaVision's failure to fully perform the terms of
          this Agreement.

      (b) NCL shall indemnify, defend and hold harmless SeaVision and its
          successors and assigns from and against any and all Losses suffered or
          incurred by SeaVision by reason of, arising out of or in connection
          with (i) any negligent, willful or

                                      -12-
<PAGE>
 
          intentional act or omission of NCL (or an employee, agent or
          representative of NCL) committed or omitted, as the case may be, in
          the course of NCL's performance of the terms of this Agreement or (ii)
          NCL's failure to fully perform the terms of this Agreement.

     10.  Further Assurances of SeaVision's Title.
          --------------------------------------- 

      (a) NCL hereby agrees to execute and deliver to SeaVision, upon the
          request of SeaVision from time to time, such UCC-1 financing
          statements and other documents as SeaVision shall reasonably require
          for the purpose of evidencing to NCL and any third party SeaVision's
          continued ownership of all components (hardware and software) of the
          System (such financing statements and other documents to describe all
          such components and to be in the form required by applicable law).

      (b) SeaVision may affix permanent (to the degree reasonably possible),
          legible and visible labels on each component of the System (hardware
          only), to the extent that doing so is reasonably possible or
          practicable.  Each such label may clearly indicate that SeaVision
          holds title to the component to which that label is affixed.

     11.  Limitation of Liability.  THE WARRANTIES AND REMEDIES EXPRESSLY SET
          -----------------------                                            
FORTH IN THIS AGREEMENT ARE EXCLUSIVE AND ARE IN LIEU OF ALL OTHER WARRANTIES
AND REMEDIES, ORAL OR WRITTEN, EXPRESS OR IMPLIED, INCLUDING, WITHOUT
LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE OR ANY IMPLIED WARRANTIES ARISING FROM COURSE OF PERFORMANCE,
COURSE OF DEALING OR USAGE OF TRADE. EXCEPT AS EXPRESSLY PROVIDED HEREIN OR
ELSEWHERE IN THIS AGREEMENT, IN NO EVENT WILL EITHER PARTY BE LIABLE FOR ANY
INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF NCL'S USE
OF OR INABILITY TO USE THE SYSTEM OR ANY PORTION THEREOF OR FROM ANY DELAY IN
THE SYSTEM ACHIEVING THE TECHNICAL PERFORMANCE STANDARDS OR FROM ANY DELAY IN
THE SYSTEM MEETING, OR ANY INABILITY OF THE SYSTEM TO MEET, EITHER PARTY'S
EXPECTATIONS WITH RESPECT TO OPERATIONS OR PERFORMANCE, EVEN IF SUCH PARTY IS
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN ADDITION THERETO, SEAVISIONS'
LIABILITY FOR DIRECT DAMAGES OF NCL ARISING OUT OF ANY OF THE FOREGOING SHALL IN
NO EVENT EXCEED THE AMOUNT OF TWO HUNDRED FIFTY THOUSAND DOLLARS ($250,000) IN
THE AGGREGATE; PROVIDED, HOWEVER, THAT THE FOREGOING LIMITATION SHALL NOT BE
APPLICABLE TO DAMAGES RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT
OF SEAVISION OR ITS EMPLOYEES. IN PARTICULAR, SEAVISION IS NOT RESPONSIBLE FOR
ANY COSTS INCLUDING, BUT NOT LIMITED TO, THOSE INCURRED AS A RESULT OF LOST
PROFITS OR REVENUE, LOSS OF USE OF THE

                                      -13-
<PAGE>
 
SYSTEM, LOSS OF DATA, THE COST OF RECOVERING ANY DATA, THE COST OF SUBSTITUTE
SOFTWARE, OR CLAIMS BY THIRD PARTIES.

     12.  Sale or Disposal of a Ship.  In the event that NCL elects to sell or
          --------------------------                                          
otherwise dispose of any Ship upon which the System is then installed, NCL
promptly shall notify SeaVision in writing of its decision.  Upon the sale of
any such Ship, the new owner shall have the option of assuming this Agreement
with respect to that Ship.  If the new owner of such Ship elects not to assume
this Agreement in respect of that Ship or in the event NCL is disposing of such
Ship other than through a sale or transfer (i.e., decommissioning), SeaVision
promptly shall remove the System therefrom, and NCL shall pay SeaVision an
amount equal to the lesser of (i) the depreciated value of the System at such
time and (ii) the amount of [Redacted - confidential treatment requested] in the
case of the S/S Norway), plus the aggregate of the cost of all new hardware and
software theretofore added to the System by SeaVision pursuant to the terms of
subsection 1(a)(iii), less the aggregate of all Adjusted Gross Revenues
theretofore paid to SeaVision in respect of that Ship pursuant to the terms of
section 3 hereof.  For purposes of determining the depreciated value of a System
for clause (i) above, the initial value of the System shall be [Redacted -
confidential treatment requested] in the case of the S/S Norway), which value
shall reduce to zero ratably over [Redacted - confidential treatment requested]
and to which shall be added the cost of new hardware and software theretofore
added to the System annually, which new additional amounts also reduce to zero
ratably over a [Redacted - confidential treatment requested] year period from
the date of each addition thereof to the System.

     13.  Public Announcements.  The parties shall consult with each other and
          --------------------                                                
issue a public statement with respect to this Agreement as soon as is practical
after the date hereof.  During the term of this Agreement, NCL shall include a
reference to SeaVision in any and all public announcements or marketing
materials referring to interactive television services on-board the Ships.

     14.  Right to Make Agreement.  Each of the parties hereto represents and
          -----------------------                                            
warrants to the other that it has all necessary and appropriate power and
authority to execute, deliver and carry out the terms and provisions hereof.

     15.  Counterparts.  This Agreement may be executed in any number of
          ------------                                                  
counterparts, each of which shall constitute an original and all of which
together shall constitute but one and the same original document.

     16.  Assignment.  Either party hereto may assign this Agreement and its
          ----------                                                        
respective rights, interests and obligations hereunder to any third party
without the consent of the other party hereto; provided, however, that no such
assignment by a party shall relieve that party of any of its liabilities or
obligations hereunder.  It is expressly understood and agreed that this
Agreement and all of SeaVision's interests and rights herein and hereunder may
be assigned, pledged, mortgaged and/or hypothecated by SeaVision at its
exclusive discretion to any third party purchasing all or

                                      -14-
<PAGE>
 
substantially all of SeaVision's assets, provided that such assignee agrees in
writing to assume all of SeaVision's obligations under this Agreement.

     17.  Successors.  This Agreement shall inure to the benefit of, and be

    I.  Entertainment and Interactive Services to be Provided by SeaVision
        ------------------------------------------------------------------


"Basic" SeaVision Package: Services Provided at No Charge
---------------------------------------------------------

     .  In-Cabin Room Service Ordering:  Passengers will be able to order NCL's
        standard room service menu, including beverages charged to their cabin
        account, through the System.  Orders will be printed out in
        appropriate pantries and/or galleys for delivery by NCL personnel.
        SeaVision shall provide, as part of the System, printers and/or
        monitors to be used in such pantries and/or galleys for such purpose.

     .  Shore Excursion Ordering:  Passengers will be able to watch videos of
        shore excursions and purchase tickets for shore excursions on and
        through the System by using their television remote-control.  Orders
        will be printed out in the Shore Excursion Office of the Ship, with
        tickets in respect thereof to be delivered by NCL personnel.  The
        System will provide appropriate inventory control.

     .  Wine Ordering:  Passengers will be able to view a wine menu on the
        System and order their selection with their television remote-
        controls.  Orders will be printed out in the Wine Steward's office or
        wine cellar, for delivery by NCL personnel at the designated meal.
        Cabin accounts will be charged accordingly.

        NCL shall be responsible for providing all ticket stock, videos and
        photographs for shore excursions and wine ordering.  NCL may choose,
        at its option, to produce its own videos and photographs, retain
        SeaVision for this purpose and reimburse SeaVision for all its costs
        incurred in connection with producing the same, or contract with a
        third party to produce such videos and/or photographs, provided,
        however, that any videos and photographs produced by any such third
        party shall in all ways meet SeaVision's technical standards for use
        on the System.  If NCL elects to have SeaVision produce any such
        videos or photographs, SeaVision shall provide NCL with detailed cost
        estimates prior to the initiation of video and photograph production.
        Such estimates will include the cost of pre-production scripting and
        preparation and the cost of sending crews aboard NCL's Ships for
        taping, photographing and post-production editing.  NCL shall pay
        these costs directly to SeaVision as a vendor.  Each party shall make
        its library of videos and photographs for shore excursions available
        to the other for the other's use in connection with the conduct of its
        business.

     .  Interface with NCL's Property Management System:  The System will
        interface with the Ship's property management system to enable
        appropriate charges to be applied to passenger accounts.
<PAGE>
 
     .  Access Control:  The System will be designed to limit access to only
        those persons who are adult passengers or who are minors under adult
        supervision.  Passengers will be able to limit access to various
        services, such as gaming and adult programming, by enabling lock-out
        codes and using password procedures.

     .  Report Generation:  The System will generate detailed activity reports,
        which will be made available to NCL for the purposes of revenue
        payments to SeaVision.  SeaVision shall also provide, at NCL's
        request, reports pertaining to passenger usage of the System.

     .  Passenger Folio Review-On-board Account:  Each passenger will be able
        to use the System to review a summary of his or her account.
        SeaVision shall provide the interfaces to NCL's on-board systems
        necessary to provide such review; provided that NCL shall reasonably
        cooperate with the development of such interfaces.

     .  Transaction Fee:  In consideration of SeaVision's provisions of certain
        services on the System at no charge, NCL agrees to consider the
        implementation of a transaction fee of not more than $1.00 per
        transaction initially for passengers utilizing the System for shore
        excursions, room service, wine ordering and other non-revenue
        generating passenger services.  Any such transaction fees will be
        included in the Adjusted Gross Revenue generated by the System.

by the following services, pursuant to and in accordance with the terms of
Section 3 of the Agreement.

     .  Video-on-Demand:  Passengers will be able to purchase movies and other
        entertainment options such as taped concerts, on demand, using the
        System and their television remote-control.  SeaVision shall determine
        the fee that will be levied for each such order and charged to such
        passengers' respective cabin accounts.  Subject to NCL's approval,
        adult programming may be offered.

     .  Gaming Options:  Passengers will be able to play video slots, poker and
        blackjack on the System.  Any additional games that SeaVision may
        desire to provide on the System shall be subject to the parties'
        mutual agreement.  SeaVision will determine the value of each
        individual credit that passengers may purchase and charge to their
        cabin accounts.  Credits may be redeemed at a location designated by
        NCL.

     .  Shopping:  SeaVision will offer passengers shopping videos and
        interactive video shopping on and through the System.  NCL will retain
        the right to approve the items offered for sale and the vendors

        for sale on and through the System, NCL shall pay all related
        production costs incurred by SeaVision directly to SeaVision as a
        vendor
<PAGE>
 
        and SeaVision will be entitled to a share of the Adjusted Gross
        Revenues generated therefrom pursuant to and in accordance with the
        terms of Section 3 of the Agreement.  Access to the System by

        on-board shops, casino, beauty salon and spa, and photographer, will
        be by mutual agreement between SeaVision and those vendors.  NCL will
        be entitled to a portion of the Adjusted Gross Revenues generated by
        any fees paid by such purveyors, pursuant to and in accordance with
        the terms of Section 3 of the Agreement.

     .  Advertising and Promotions:  SeaVision shall have the exclusive right to
        provide access to the System to third parties for the purposes of

        NCL shall retain the right to approve such third party advertisers as
        will be given access to the System and the manner in which any such
        advertising is presented.  NCL shall designate the individual
        responsible for granting such approvals on its behalf, and such
        individual shall provide SeaVision with general guidelines for
        advertising and marketing activities and the procedure SeaVision shall
        follow in submitting advertising and marketing proposals for NCL's
        consideration.  NCL shall not unreasonably withhold its approval of
        advertising and marketing proposals with respect to the System.  NCL
        shall notify SeaVision of its approval or denial of an advertising or
        marketing proposal within 14 days after SeaVision's written submission
        thereof.  In the event NCL fails to notify SeaVision of its decision
        within that period, it shall be deemed to have approved that written
        submission.  NCL will be entitled to a portion of the Adjusted Gross
        Revenues generated by such advertising and marketing promotions on the
        System, pursuant to and in accordance with the terms of Section 3 of
        the Agreement.

        applications which will provide an entertaining and easy-to-use
        graphical, touch screen interface to purchase "instant" photographs
