Creating 100% Pathogen Free Environments

April 13, 2010 — Medizone International to Attend Investors Conference

San Francisco, California April 13, 2010 Medizone International, Inc. (MZEI.OB) announces it will be attending the Accredited Members, Inc. conference being held at the Green Valley Ranch Resort in Las Vegas, Nevada between April 20th and 22nd. Accredited Members sponsors a number of conferences each year, which interface emerging companies such as Medizone International with previously qualified high net worth accredited investors looking for new opportunities.

Edwin Marshall, Medizone’s CEO and Board Chairman who will be attending, commented, “I am pleased to have been invited to this conference and enthused about the opportunity to showcase Medizone and our AsepticSure™ technology to an estimated three hundred qualified investors at one time.  As we are about to start our hospital beta test program, we must also look forward to our projected capital requirements for entering production and sales later this year.  I believe by attending this conference and the Vail conference scheduled for June 7-9, it is likely we will be able to fully fund all of our needs through initial production.” Mr. Marshall went on to say, “Another bonus to the conference is the opportunity to be introduced to the global audience of Don Baillargeon’s MoneyTV show, as he will be filming a segment of the show at the conference.  MoneyTV has been on the air for more than 14 years and over 650 episodes. They have a global distribution of 170 million TV households. The US distribution is more than 70 million TV households.  My personal opinion is that our stock price is currently significantly undervalued.  I expect our presence at the upcoming conferences in Las Vegas and Vail, combined with being on MoneyTV, will greatly increase the number of eyes on Medizone and our phenomenal product, AsepticSure™.”
