United Kingdom Registration of New Insect Repellent Product NO-SKEETO!™ 

Field Trials Demonstrate Superior Performance Over Current Market Leading Products

TyraTech, Inc. (AIM: TYR and TYRU), a natural life sciences company, is pleased to announce that the Company has been granted permission to sell its new personal insect repellent in the United Kingdom. This means that the product is approved and ready for immediate commercialization in retail channels. NO-SKEETO!™ features TyraTech's Nature's Technology™ platform which harnesses the power of natural ingredients to deliver best-in-class efficacy and family safety.

Both Laboratory and Field trials have demonstrated that NO-SKEETO!™ significantly outperforms 15% DEET for both mosquito and tick repellency. Trials have been carried out using various species of mosquito including those which are known vectors of West Nile Virus, Malaria, Dengue fever, yellow fever and St Louis encephalitis. Tick trials have included species which are vectors for Lyme disease, Rocky Mountain spotted fever and Southern tick associated rash infection (STARI).

The Company has filed for patent protection for its NO-SKEETO!™ formulation and has submitted data from the laboratory and field trials for publication in two international journals. The Company has already been granted registration for NO-SKEETO!™ in the U.S. and German markets.

David Paton, TyraTech's Head of European Operations, said "NO-SKEETO!™ provides an effective and timely solution for families seeking superior protection without concerns over safety. Our portfolio of European registrations is expected to continue to grow in the coming months. We are currently in the process of evaluating commercial and retail partners for this product and for our other products."
