2. Overview • Introducing LifeNet • Biological performance • Textile testing and strength • User acceptance • Translating technical performance to cost effectiveness page 2 • •

3. Introducing LifeNet… • The first LLIN made of polypropylene • Effectiveness independently validated beyond 35 washes • Improved textile strength validated in laboratory tests • Soft to touch and pliable • Improved efficacy against Culex mosquitoes • Reduced flammability compared to polyethylene and polyester nets • ISO certified for environment impact page 3 • •

4. Biological efficacy overview page 5 • •

5. A new standard in wash resistance Results after 50 washes Reference: Business Confidential Trial Report - Jung R. 2010, BioGenius, Germany page 6 • •

6. A new standard in wash resistanceNo regeneration delay The full efficacy of LifeNet against Anopheles mosquitoes is restored within few hours after washing. The surface of LifeNet is recharged with active ingredient from the reservoir within the fibers, due to its slow release system. Reference: Business Confidential Trial Report - Nentwig G. 2010, Bayer Cropscience, Germany page 7 • •

7. “Even after 35 washes, bio-efficacy complied with the WHO criteria” Report of the 14th WHOPES Working Group Meeting. page 8 • •

8. Textile testing overview page 9 • •

9. An extensive range of textile tests to support our performance claims • LifeNet has undergone a broad range of textile tests • A broad range of tests gives a better picture of performance under real-life conditions • Bursting strength (ISO 19338-1:1998) • Dimensional stability • Slow Nail Test • Dynamic nail test • Abrasion resistance • Tensile strip tests • Thermal aging • Soiling • Dynamic bagging • Stonewashing page 10 • •

10. Bursting strength A standard method which assesses the strength of a piece of net in ‘all directions’ LifeNet was shown to be the strongest and both panels and seams had consistent strength. page 11 • •

11. Dimensional Stability Assesses the change in dimensions of a piece of netting after five washes at 40 degrees centigrade LifeNet showed the least degree of dimensional change after this washing regime page 12 • •

12. Slow Nail Test Pieces of net are slowly pulled against a fixed nail (in both directions of row and column). LifeNet showed the best balance of strength in both directions page 13 • •

13. Dynamic Nail Test Pieces of net are rapidly pulled against a fixed nail (in both directions of row and column). LifeNet showed the best balance of strength in both directions page 14 • •

14. Textile testing results overview • The multifilament polypropylene fiber construction of LifeNet results in a net with stronger mechanical properties than polyester and polyethylene nets. • Stronger nets are less likely to develop holes and damage during use – effectively providing longer protection under field conditions page 15 • •

15. The influence of net characteristics on behavioural attitudes towards net usage page 16 • •

16. LifeNet favours high end-user acceptance • Soft to touch • Good ventilation properties • Improved freefall • Easy foldability page 17 • •

17. Translating technical performance to cost effectiveness page 18 • •

18. More nights of protection per net Longer lifespan of net + Greater end-user acceptance • Wash resistance • Mechanical strength • Soft • Ventilation • Freefall • Foldability Increased number of nights of protection More protection for every $ spent page 19 • •
