About BioLargo, Inc.

BioLargo, Inc. is currently engaged in pre-licensing and product
evaluation with strategic partners to leverage a suite of patented and
patent-pending intellectual property, the BioLargo technology. The
BioLargo technology harnesses and delivers nature's best disinfectant
- iodine - in a safe, efficient, environmentally sensitive and
cost-effective manner. The BioLargo technology, the centerpiece of
which is CupriDyne(TM), works by combining minerals and salts with
water from any source to generate and deliver molecular iodine on
demand, in controlled dosages, in order to balance efficacy of
disinfectant performance with concerns about toxicity. When the
BioLargo technology is incorporated in absorbent products, third-party
testing has confirmed that the products also experience increased
holding power, and the company believes that they may also experience
increased absorption. The company's website is www.biolargo.com.
