                           CONCESSION LEASE AGREEMENT

      This Agreement, made and entered into this 15th day of February, 2000, by
and between PARAMOUNT PARKS INC., a Delaware corporation (herein called
"Paramount") and RX TECHNOLOGIES (herein called "Lessee").

                                   WITNESSETH:

      In consideration of the mutual covenants, terms, provisions and conditions
herein contained, the parties hereto represent, warrant and agree as follows:

                                    ARTICLE I

                                LICENSE AND TERM

      Paramount owns and operates a theme park known as Paramount's Kings Island
(the "Park") located in King's Island, Ohio.

      Paramount hereby licenses to Lessee, and Lessee hereby licenses from
Paramount, the premises in the Park described in Exhibit A attached hereto
(herein called "Premises") together with ingress and egress for a period
commencing as of 1 April 2000 and ending 1 November 2000, which period is herein
called the "term" of this Lease Agreement.

      Except as specifically set forth herein, no easements, appurtenances,
hereditaments, or other rights or interests whatsoever, are licensed or
otherwise granted hereby in the Park.

                                   ARTICLE II

                                 USE OF PREMISES

      Lessee shall operate four (4) locations (herein called "Exhibit") on the
Premises for the purpose of producing and selling photographs of guests, as well
as providing the service of transmitting those pictures via e-mail, at the
Beast, Vortex, Outer Limits, and Taxi Jam rides as further set forth and
described on Exhibit A hereto. Lessee may not use the Premises for any other
purpose or conduct without the prior written consent of Paramount.

      In case any doubt arises regarding the proper use of the Premises, Lessee
will submit a request in writing to Paramount for an interpretation and
determination of its rights under this Article. Paramount's decision thereon in

                                       1
<PAGE>

writing, based upon the operating plans and policies of the Park and based upon
the description of Lessee's Exhibit hereunder, shall be final; provided that
such determination shall be in the sole discretion of Paramount. Lessee shall
not take any action without receiving, or in contravention of, such
determination.

      All items to be sold or given away and all items used in the preparation
of items so sold or given away at Lessee's Exhibit shall be of the highest
quality. Paramount reserves the right to prohibit Lessee from distributing items
which are not, in its sole discretion, of the highest quality or the
distribution of which, in its sole discretion, is not consistent with the
reputation of the Park.

      All items sold by Lessee at the Park shall be sold at prices mutually
agreed upon by Paramount and Lessee.

                                   ARTICLE III

                    CONSTRUCTION AND INSTALLATION OF EXHIBIT

      Lessee shall plan, install and erect any additions to and improvements
upon the Premises required for the Exhibit. Such improvements shall be of the
highest quality, of sound and safe structure, and in accordance with the
policies, motifs, designs, and overall planning for the Park and the particular
theme areas thereof in which such improvements shall be installed. Improvements
made by Lessee shall be subject to Paramount's prior written approval.

      Lessee agrees to promptly reimburse Paramount for all construction costs
incurred based on cost estimate mutually agreed upon by both parties.

      Lessee agrees to incorporate to Paramount's satisfaction and at its own
cost new technology into the Exhibit as it becomes available in order to
maximize revenues.

                                   ARTICLE IV

                TITLE TO TRADE FIXTURES, IMPROVEMENTS, EQUIPMENT

      Any improvements, other than trade fixtures installed on the Premises by
Lessee with Paramounts prior approval, made on or to the Premises, shall, upon
termination of this Lease Agreement, become a part of the Premises, title to
which shall be vested in Paramount. Upon the termination of this Lease
Agreement, Lessee shall have the right to remove all trade fixtures installed by
Lessee, title to which it has retained, from the Premises and shall, at its
expense,

                                       2

repair and restore the Premises (including all improvements thereto) to the same

      Paramount, its agents and employees retain the right to enter upon and
inspect all portions of the Premises and Exhibit at any reasonable time. In the
event entry is necessary and Lessee is not present to permit such entry,
Paramount may enter the Premises, forcibly or otherwise, without rendering
itself or its agents or employees liable to any claim or cause of action for
damages, except as provided below, and without affecting the obligations and
covenants of this Lease Agreement. In the event Paramount's action causes damage
to Lessee's property upon the Premises, Paramount shall repair or replace such
damaged property unless such action was necessitated by Lessee's negligence or
willful misconduct.

      Paramount shall have the right to enter upon the Premises to accomplish
such work as may be necessary to preserve the walls, structure, or other parts

(including charge backs, dealer discount*, etc.) will be deducted from Lessee's
share of revenue.

      Cash register shortages (not errors), if any, are for Lessee's account

      ticket value for the privilege of using their card. That fee is referred
