ARTICLE THIRTEEN:  -  In conformance and compliance with the terms
and conditions of the proposed Strategic Partnership Agreement
between Americel and Platforms, Platforms hereby CONFIDENTIALLY pre-
releases information to Americel about its ARC System Phase-II
unmanned airborne vehicle - The ARC System StratoStar Airship.

A.  The StratoStar Airship is a unique, high altitude (50,000 to
65,000 ft) unmanned, maneuverable recoverable, and reusable high-
altitude AirShip manufactured of Kevlar 29 and a proprietary
polyethilene film combination that allows the formation of an ultra-
light, pneumatic structure with a skin resistant to the hazards of
high-altitude environments.

B.  The StratoStar is a tri-hull airship with an overall length of
336', an individual hull length of 300', a diameter of 62', a height
of 80', and a total volume displacement of approximately 2.5 million
cubic feet.  The StratoStar uses helium to achieve the airship's
pneumatic form, its lift, altitude maintenance, and for safety of
operations.  Three electric engines with oversized propellers are
used for propulsion and station-keeping operations.  Solar power is
collected through photo-voltaic cells and stored in high-capacity
electrical storage lithium batteries.  Platforms' proprietary
hardware and software flight control systems direct the flight
operations of the airship.

C.  The StratoStar is designed to remain in its designated, computer-
guided, GPS-controlled stratospheric station for periods of six
months or more, before returning to its ground base station for
maintenance and redeployment.

D.  Pricing of a StratoStar 10-year lease program is presently NOT
FINALIZED.  However, in response to your request for a pricing
estimate, our preliminary, CONFIDENTIAL price for a 10-year lease
program under our exclusive Strategic Partnership Agreement with
Americel is estimated as follows:

     (1)  Platforms estimates it should be in a position to deliver
the first StratoStar ARC System Airship to Americel in eighteen to
twenty-four months, after the delivery of the first aircraft-based
ARC System.

     (2)  Platforms agrees to replace and upgrade all Americel
aircraft-based ARC Systems to StratoStar Airship Systems as soon as
the new airships are ready for commercial delivery.  Immediately upon
initiation of StratoStar ARC System Airship operations, the monthly
Maintenance and Operations fees to Americel for each StratoStar ARC
System AirShip installation shall be reduced from FIVE HUNDRED
THOUSAND (USD $500,000.00) DOLLARS to TWO HUNDRED AND FIFTY THOUSAND
(USD $250,000.00) DOLLARS per month.

     (3)  Platforms gross revenue participation on the first
Stratostar ARC System Airship shall be EIGHT (8%) PERCENT.  On all
subsequent Systems it shall be FIFTEEN (15%) PERCENT.  As part the
exchange and upgrade program to the StratoStar ARC System, all ARC
System aircraft related equipment shall be returned to Platforms.

     (4)  Estimated lease program for second, third, fourth, fifth
(non-replacement and upgrades) StratoStar ARC System Airships should
operate as follows: (i) a fixed License Fee of TWELVE MILLION (USD
$12,000,000.00) DOLLARS, payable upon contract execution; (ii) annual
maintenance and operations fees of THREE MILLION (USD$3,000,000.00)
DOLLARS, payable in monthly installments of TWO HUNDRED AND FIFTY
THOUSAND (USD$250,000.00); DOLLARS; (III) FIFTEEN  (15%)PERCENT gross
revenue participation.

ARTICLE FOURTEEN: The Court for the resolution of any differences or
to enforce any rights or obligations arising from the terms and
conditions set forth in this Agreement, shall be Brasilia, Brazil.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement
effective as of the 7th day of April 2000.
