     LICENSE AGREEMENT BETWEEN ANTON SIMSON, EESTI Engrg, LLC, POWAY, CA,
     LICENSEE & JOHN H. COVER, LICENSOR - under Pat. No. 5,078,117 (generally
     covering the use of compressed gas capsules that are easily discharged &
     the gas will propell projectiles, weights, contactors, nets, etc., in a
     non-firearm mode of operation).

     This Agreement specifically pertains to EESTI's manufacture of Taser-type
     cassettes designed to snap onto stun guns giving the stun gun owner the
     Taser stand-off range & effectiveness in stopping power over dangerous
     criminals.

     More specifically this License relates to J.H. Cover's License with Eastex
     Co., Yong Park, who imports & sells the Thunder Power - and other stun guns
     - which will be used in conjunction with the EESTI SGA Cassettes containing
     the SPOGC's.

     In return for this Exclusive License to EESTI, J.H. Cover will receive an
     Earned Royalty from Anton Simson, EESTI, of $0.25 - or 25(cents) @ for each
     SGA Cassette they Make & Sell.

     In summary, the Licensor, John H. Cover, hereby grants an Exclusive License
     under Patent #5,078,117 to Anton Simson, d.b.a. EESTI Engineering, LLC, to
     manufacture and sell the Stun Gun/SGA Taser Cassettes as the Exclusive

Bestex Co., Unit B                      Bestex Sale of a Stun Gun
3421 San Fernando Rd.          Adaptor/SGA designed for the Thunder
Los Angeles, CA 90065          Power Stun Gun.

ADDENDUM TO THE LICENSE AGREEMENT signed by Yong Suk Park, d.b.a. Bestex Co.,
3/7/90 & John H. Cover, Licensor, on 2/19/90.

Licensor hereby grants an Exclusive License to distribute and sell the SGA
Taser Cassettes designed to "snap" onto the front of the Bestex Thunder Power
Stun Gun modified to function with the SGA -- which projects the high voltage
electric contactors at an attacker -- such that the user does not receive a
shock to this hand (insulation)

This License is under J.H. Cover's Patent #5,078,117 covering the
Self-Puncturing Compressed Gas Capsule. This technology permits the use of
compressed air to propell the contactors & is therefore not classified as a
Firearm. EESTI, Anton Simson, Poway, CA will make the SGA under my Patent
License & supply them to Bestex.

The Terms for Bestex's Exclusivity are: 1)$20,000 upfront ($10,000 upon
execution of the License -- 1st week of March, 1996 -- and $10,000 April 1,
1996), 2) Bestex's Minimum Royalty will be $2500/mos starting 4/2/96, and 3)
Bestex will pay J.H. Cover $2 Earned Royalty for each Thunder Power Stun Gun
sold(or any modification or substitution thereof that fits the SGA) and
25(cents) for each SGA Cassette sold.

It is important that Yong Park, Anton Simson & Jack Cover work as a team on
this program. There are decisions to be made such as the Packaging of the
Product -- the Thunder Power & (2) SGA cassettes in a box -- sales and
advertising strategies including the name of the Product. "Public Defender" and
ElectroStorm(stop rape & murder) are possibilities. An early meeting such as
the first week in December is suggested. Jack Cover will consult as needed
without compensation.

The signatures below constitute the legal acceptance of the two parties of the
above terms & conditions.
