ShockRounds - World's First "Electric" Less Lethal Bullets Successfully Tested

SANTA CLARA, CA Jun 30, 2005 - MDM Group, Inc. (OTC.PK: MDDM) advises that its Australian listed subsidiary, Harrington Group Limited (OTC.PK: HGRLF) or Australian Exchange (Australia:HGR.AX), earlier today advised the Australian Stock Exchange and media of its successful firing of the ShockRounds(TM) "electric" bullet prototypes that were repeatedly fired from a 37mm Federal Labs firearm.

This breakthrough testing is the first time in the world that wireless electrically charged bullets have been fired from a standard issue firearm.

The Harrington Group Press Release and also the Media Release can be accessed at www.hgrltd.com under News.

MDM Group President Mr. Peter Boonen stated: "We are exceptionally pleased that we are able to confirm that ShockRounds(TM) can be fired by standard issue firearms. This testing is the first time that electrically charged bullets, without attaching wires, have been fired from a firearm."

He added: "ShockRounds(TM) will introduce a new level of stopping power to the munitions industry both for the specialized rubber bullet market as well as for the traditional lethal firearms market. ShockRounds(TM) enabled rubber bullets will provide law enforcement officers with a dramatically increased effective range of up to 100 meters and with ShockRounds(TM) lethal bullets we forecast that, by adding electric shock capability, less shots would be fired in any confrontation thereby greatly increasing the level of safety in conflict for the law enforcement officers as well as for any innocent passers by."

ShockRounds(TM) are a potential breakthrough product for the law enforcement industry, the military, border control, and anti-terrorism initiatives, due to their versatility and multiple applications. When fired, a ShockRounds(TM) enabled bullet generates an extremely high-voltage charge that is discharged upon impact with the target.

ShockRounds(TM) "electrified" standard bullets and rubber bullets are forecast to:

-- Make law enforcement safer and more certain
-- Save lives and ensure less collateral damage
-- Reduce injuries and fatalities
-- Enable far better control and effective enablement in aircraft, public places, arenas, etc.
-- Provide an effective anti-terrorism and border control weapon
-- Decrease legal liability and revolutionize the munitions industry
