Hospital acquired infections are the fourth largest cause of death in U.S… Page 4 The issue is significant and actions are being taken Timing is right The issue is significant and actions are being taken Timing is right HOSPITAL-ACQUIRED INFECTIONS KILL 270 PEOPLE A DAY in NYC alone (Source: Deadly Admissions: Hospital-Acquired Infections Are 4th-Largest Killer in U.S., But Ohioans Cannot Get Statistics to Compare Facilities By Tracy Wheeler, The Akron Beacon Journal, Ohio Jan. 9--But for 20 million Americans each year -- about one in every 10 to 20 patients -- a trip to the hospital results in dangerous, lingering infections, whether through surgery, dialysis, ventilators, IVs, or catheters. At an estimated 90,000 deaths a year, these hospital-acquired infections kill as many people in the United States as AIDS, breast cancer and car accidents combined.

The Problem Value Proposition: Safety and Economics Page 5 Healthcare related organizations develop more stringent standards: The Center for Disease Control (CDC) puts out “Guidelines for Disinfection and Sterilization in Healthcare Facilities, 2008” outlining Harsher disinfection chemicals More frequent cleaning The Joint Commission (TJC) incorporates tougher disinfection protocols in their guides for high risk environments in hospitals such as emergency and operating rooms, trauma bays, procedure rooms. The Result: Traditional wall paints are not holding up long term to the increased scrubbing and harsher chemicals

The Problem Value Proposition: Safety and Economics Page 6 Meanwhile, insurers recognize the issue and take action: Medicare changes their insurance protocols: As of January 2009, will not pay for Hospital Acquired Infections (HAI) Treatment costs will belong to the hospital Soon after, most major medical insurers follow The Result: Hospitals enact increased preventative measures to greatly reduce the chance for HAI for patient safety and economic viability

Defining the Problem Multiple Points in the Value Chain Page 8 To define the unmet need, we engaged stakeholders: Hospital Facility Managers Architect/Spec Writers Hospital Administrators Painting Contractors Hospital Accreditation Organizations And listened to how they defined the problem

Research from Key Hospital Personnel Goal: Reduce repaint cycle, keep areas safe, save money Page 9 After listening, we heard that they wanted: A more durable, scrubbable wall coating in the high risk areas A very low odor coating that would not disrupt operations ‘Warmer’ eggshell or matte coatings but still have durability An easier to clean and seamless surface Less downtime in these high operating cost areas To use their in-house painters more on patient rooms and hallways

Input from Healthcare Community Hospital Facility Managers and Administrators The Preferred Attributes from Around the Country

The Value Proposition From the Hospital’s Point of View Page 12 For the hospital administrator who is concerned with meeting the CDC protocols without sacrificing aesthetics and durability, a new high durability coating technology has been developed for rooms requiring frequent cleaning that offers improved durability and resistance to harsh cleaners and disinfectants without sacrificing appearance. Compared with conventional wall paint: 4x more durable and scrub-able Same ease of use, color palette, and low gloss finish Compared to tile: 4-5x lower cost Better design latitude for future color schemes

The HD Wall Coating Technology Architectural Wall Paint Alternative Page 14 Two Component Waterborne Polyurethane Technology Built on Bayer’s HD Wall Coating Technology Attributes: High Durability even in an eggshell or flat finish ‘Silky’ surface makes cleaning easier Excellent chemical and disinfectant resistance Very low odor during installation and drying Ultra low VOC and solvent at 15g/l or less Same color palette as traditional architectural wall paint

Waterborne Technologies: 2K chemistry with excellent overall properties “Water is Green” Early “waterborne” coatings had as much as 300g/l of co-solvent New commercial systems are now at 0-15 g/L Offer viable replacement products to solventborne epoxy or polyurethane systems The Technology 2K Waterborne Coatings
