1 To: Mr. Golan CoverTop ltd. RE: EMF Radiation Reduce Justification and Measurements of Electromagnetic fields on Cover Top cover for use with Laptop computers. Dear Sir, Following your request, On January 29-30, 2012, we preformed a series of measurements of Electromagnetic fields that source out form Laptops computers signals including RF, ELF and EMF, in Cover Top Lab in Rehovot, Israel. The purpose of the measurements is to check the electro magnetic fields that are emitted from use of Laptop computers and to compare it when using the Laptop computer with CoverTop shield cover for laptops, The WHO/International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer1, associated with wireless phone use.( PR #208 Lyon, France, May 31, 2011 ) The results of the test showed that using CoverTop shield cover eliminates up to 30% of electromagnetic radiation emitted from the Laptops Computers,RF radiation by up to 35% then working directly on the and ELF radiation by 33% then working directly on the. Using CoverTop shield cover on Laptop computer is completely safe and well recommended to use while using Laptops computers *Measurements are right for the place and moments of the test. 1 of20

Testing Protocol Environment Condition The Measurement took place at the Lab Area, in various distances from the Laptop computers transmitters. The Measurements were performed between 09: , With different models of laptops computers, and different data transfers 3 of20

4 Source of Electromagnetic Fields In The Laptops computer there are different sources of RF and ELF electromagnetic fields. RF (2400Mhz- 2500Mhz) laptops computers use electromagnetic radiation in the microwave range to transmit and receive signals and data MHz Bluetooth and WiFi internet connection. EMF magnetic fields that may be emitted from the speaker on regular laptops and the power supply unit located in the back side of the laptop computers. Those RF/ELF sources generate the Electromagnetic Fields that are required in order to transmit the signals and hear the sounds. Most of the sources are not working all the time, but only during activation of the laptop and internet downloads. Parameters that checked 1. Electric Field power [ V/m] 2. Power density [µw/cm²] 3. Magnetic Fields [ mg ] Service provider and mobile TR systems. 1. Wi-Fi internet connection 4 of20

Operate the different Laptops Computers in Nominal Working state, while forcing the system to be in different Transmission forces, while measuring the Value of the Field in different Distances from the Laptop Computers. Laptops Computers in use from different models and service providers. 1. Transmission in low and high mode. 2. Stand by. The test was conducted on various models. Similar computers with the same level of radiation will provide the same results. 3. Pictures 5 of20

20 Summery of Test Results Conclusions and advises: After running all the required tests and measurements and analyzing the data, we indicate that using the shield cover CoverTop on the laptops prevent the Electro-magnetic fields and waves caused by the Radiation emission from the Laptops Computers up to 35%. This kind of radiation emitted from Laptops Computers is worrying the World Health Organization declared on 31 May 2011 that RF Radiation from Laptops Computers can possibly cause cancer. They now list mobile phone use under the same "carcinogenic hazard" category as lead, engine exhaust and chloroform. Using CoverTop shield cover eliminates electromagnetism radiation emitted from the Laptops Computers. 1. Using CoverTop reduces the RF radiation by 35% comparing to direct use of Laptops Computers. 2. Using CoverTop reduces the ELF radiation by 33% comparing to direct use of Laptops Computers. 3. Today, governments and health organizations around the world put restrictions on the use of Laptops Computers, especially with kids. Using this kind of cover will prevent the risk the world health organization is worried about. 4. We recommend using this CoverTop shield cover device in all of your Laptop Computers use as prevention - caution action in order to be on the safe side.
