1 Product Features Comparison with Super DHG Series Next Generation Filters for Digital SLR Photography EXUS Series Marumi Optical Co., Ltd. Tokyo, Japan Argraph Corporation Carlstadt, NJ Strictly Confidential

2 Digital cameras are constantly advancing. Today, models equipped with high-tech features such as 35mm full-frame digital SLR image sensor are within reach of average consumers. In other words, the age of high-quality, high-performance digital cameras is here. The new EXUS Series – the flagship of Marumi digital camera filters features exceptional performance and functions that are ready to meet and exceed the demands of the latest digital SLR cameras. The Background 2

3 What is EXUS ? What is EXUS ? EX = Experience, Excellence,… Marumi has over 60 years experience specializing in excellent filter technology and manufacturing EX = Experience, Excellence,… Marumi has over 60 years experience specializing in excellent filter technology and manufacturing U = Ultimate, Ultra,… Marumi developed the ultimate filter U = Ultimate, Ultra,… Marumi developed the ultimate filter S = Spec., … with full specifications. EXUS features the ultimate specifications based on Marumis expertise and technology. S = Spec., … with full specifications. EXUS features the ultimate specifications based on Marumis expertise and technology. 3

4 What is EXUS? The name EXUS derives from the words Experience, Ultimate, and Specifications. EXUS filters feature the ultimate specifications based on Marumis expertise and technology. EXUS 4
