COMMISSION ACTION: Thorguard.com httn.//thrn-crll<lrrl {'("\m/<lhrlllt <l",n ATTACHMENT #1 Our Mission THOR GUARD, the leader in lightning prediction, is committed to utilize emerging technologies in the development of systems that provide automatic notification of hazardous weather conditions. Company Profile The THOR GUARD Lightning Prediction System has been manufactured in South Florida since 1976. Over the ensuing years, representing literally millions of hours of accurate and safe operations, THOR GUARD has consistently proven its reliability. THOR GUARD uses a highly sophisticated sensor and computer to measure and analyze the electrostatic field in the atmosphere. Lightning originates within this field, thus allowing THOR GUARD to make calculations predicting its occurrence, even though there may be no visible evidence of lightning. Lightning "detection" systems require the occurrence of an actual lightning strike before a warning is given. Many times this is just too late. Many airlines, explosive companies, government agencies, and other industrial users are utilizing THOR GUARD for this very reason. THOR GUARD is the only stand alone lightning warning device used by most sections of the United States Golf Association, LPGA and many local sections of the PGA of America. We are the choice of Marriott Golf, The PGA Tournament Players Clubs, ABC Television Sports, and the Atlanta Summer Olympics. The flexibility of our system not only accommodates private golf facilities needing plenty of advance warning (20 or more minutes), but also public facilities looking at only 8 to 18 minutes of warning to insure revenue flow. THOR GUARD is also highly regarded and utilized by many non-golf industries as well. Some of out significant customers include American Airlines, Delta Airlines, Air Canada, United, Fed Ex, Phelps-Dodge Mining, Motorola, AT&T, and over 700 universities, schools and municipalities. From airports and ski areas to the NFL and zoos, THOR GUARD can be found providing on-site, real-time lightning prediction and warning to perfection! THOR GUARD's PREDICTION capability also minimizes false alarms, a significant departure from detection systems that are prone to unnecessary and costly shutdowns! Municipalities have also recognized the need for our early warning prediction system. Parks, pools, playgrounds, schools, and other public facilities are now relying on our system. THOR GUARD predicts the probability of a lightning hazard in an area up to 25 square miles. More importantly, it also provides a specific reading of the risk in your immediate area. Couple the PREDICTION capability of a THOR GUARD with the Voice of THOR, our interactive horn warning system, and you have a true automatic advance warning package second to none! Product Development History THOR GUARD stands alone in the market as the most effective predictor of lightning within a defined area of risk. This is the result of the founders' decision, in the late 1960's, to focus research efforts on the study of the electrostatic field (the energy field of which thunderstorms are composed). The more conventional study of 1/7Q/7nm Thorguard.com httD:! /thOH!Uard.com/aholltasn Page 2 of2 the electromagnetic field (the field that is affected as a result of a lightning discharge), has continued to be the focus of lightning detection systems. THOR GUARD effectively reads the activity within the electrostatic field through a proprietary program developed after hundreds of hours of thunderstorm monitoring, and will predict the probability of a lightning strike within a predetermined area of concern. This program can also project the potential for deadly "bolts out of the blue," which are strikes that seem to come from nowhere and cause a high percentage of lightning fatalities. These are the significant technical advantages that have allowed THOR GUARD to become the most accurate and meaningful advance warning system of lightning potential. Patents on the basic technology employed in the system are based on developments produced originally from 1968 to 1985 by Electrofields, Inc., the forerunner in the field of lightning prediction. Electrosensors, Inc. (now THOR GUARD, Inc.) purchased all trademarks and patents and an aggressive program of research and development was initiated. During the ensuing years THOR GUARD, Inc. has continued to upgrade the system in both practical field applications, and the science of modern day computer technology. THOR GUARD has provided accurate and dependable lightning prediction for a broad base of clients since 1974. This represents literally millions of hours of safe operations.

Why do these organizations promote only lightning detection and not lightning prediction systems? {) Exactly what is THOR GUARD's role with professional golf and the 1996 Atlanta Olympics? (>> Is it true that there is no statistical or data based evidence that THOR GUARD predicts lightning? f) How do your warranties and representations compare to other's? o What is the difference between lightning "protection" and lightning "warning" devices? o What is the audibility range of one Voice of THOR horn warning remote and is this system capable of operating solely on solar power (no wires)? (D) Does your system shut down due to cloud to cloud discharges like detection systems or is it prone to giving false alerts ("false positives")? o How does lightning "Prediction" differ from lightning "Detection"? Lightning "detection" systems detect the electromagnetic signatures that are the by-product of actual lightning strikes. Lightning "prediction" senses and evaluates the shifts and changes in the electrostatic field that precede the occurrence of an actual lightning strike. This is the reason why our unique lightning prediction technology has always been able to provide warning before the first strike. According to a leading lightning detection manufacture's specification sheet, they need three strikes within 10 miles before they achieve peak operation. What if the first strike is right on top of you? o How much advance warning can I expect from a THOR GUARD lightning prediction system to find appropriate shelter? The THOR GUARD system has been designed to offer various sensitivity levels in order to satisfy a diverse range of client needs and geophysical locations. In a typical user-selected range (12 mile/2 miles) the system would provide 8 to 20 minutes advance warning. It is important to note that lightning does not need to be visible before a warning is given. Our unique "Field 1/29/2007 Thorguard.com htto ://thonmard.com/faa .aSD Page 2 of 4 Collapse Counter" is the most accurate lightning detection method in existence today and will respond to subtle migrations of potentially dangerous energy. o Is there a minimum acceptable range for how close a lightning strike has occurred before shutting down operations? This is not an issue when using a THOR GUARD system because we are predicting strike probabilities for your immediate area of concern and updating the data 50 times a second. For lightning detection systems, however, the choice of the correct range is critical. The most recent data from a 1998 study by Messrs. Holle & Lopez (Severe Storm Center) would indicate that the minimum acceptable range from the last strike should be no less than 6-8 miles. This obviously would indicate that waiting for lightning to reach the previous standard of a 0-5 mile range, is dangerous. The new data also challenges the popular "Flash to Bang" theory because lightning can rarely be seen and/or thunder heard, as far away as 6-8 miles o Internet searches have revealed a few organizations that give the appearance of being the authorities on lightning. Why do these organizations promote only lightning detection and not lightning prediction systems? While appearing to be independent and objective, many of these associations have in fact been created to further the best interests of one company. If you look closely at the makeup of these groups, you will notice many of the same names listed as Board Members, employees and advisors. Further scrutiny will reveal an association with a dominant lightning detection manufacturer. While offering some pertinent advice on lightning, most of these organizations are critical of our products because it is in their financial best interest to do so. €J Exactly what is THOR GUARD's role with professional golf and the 1996 Atlanta Olympics? THOR GUARD is the only stand-alone lightning warning system used by the PGA Tour (see "Customer Responses"), the LPGA Tour, the PGA Senior Tour, Buy.com Tour, Golden Bear Tour, Lone Star Tour, and all PGA major championships. THOR GUARD can be found at 75 USGA sections, 9 PGA sections, the PGA of America, at all USGA championships (lightning detection equipment occasionally used at USGA events), and was at every Atlanta Olympic venue except Sailing. Our system has been "tournament tested" through thousand's of hours of operation - NO False alerts - NO late notices. Don't take our word for it, check it out!. o Is it true that there is no statistical or data based evidence that THOR GUARD predicts lightning? No it is not true! Actually there are several patents on the system dating back i/7Q/70m Thorguard.com httn.//thrlrall!:1rrl rrlITl/f!:1n !:1<:n Page 3 of 4 to the 1970's proving its unique abilities and adherence to a strict database system. The, further enhancement of this science is proprietary and therefore not available for publication. o How do your warranties and representations compare to other's? We provide a four-year warranty on any prediction system that we manufacture and Voice of THOR warning systems for two years. While some detection manufacturers may also offer a two-year warranty, the horn warning systems sold with them do not! Our company also offers an extended warranty on all THOR GUARD lightning prediction models, as well as free software upgrades for ten years. o What is the difference between lightning "protection" and lightning "warning" devices? If you should hear that the THOR GUARD product is not a "protection" device or system, that would be correct. We offer lightning "warning" systems, not "protection" systems. According to the "Lightning Protection Institute" a lightning "protection" device provides actual protection against a strike. In this category are surge suppressors, lightning rods, grounding systems, large buildings, etc. THOR GUARD WARNS PEOPLE, BEFORE A STRIKE WILL HIT, TO GO AND SEEK "PROTECTION"! Any company that represents that a lightning detector or horn warning system is lightning "protection" does not understand the facts. o What is the audibility range of one Voice of THOR horn warning remote and is this system capable of operating solely on solar power (no wires)? The normal range of one "horn cluster" (six, air-horns) is 700-800 yards, in a 3600 pattern. Typography, tree density, air moisture content and ambient noise are all factors that will affect performance, (Example: A normal 18-hole golf layout will need (1) Base Transmitter/Horn Cluster and (2) Remote Receiver/Horn Cluster locations. More than 95% of all new installations now utilize solar power as the primary power source (not just as a backup like competitive systems). We actually prefer the solar option because access to external power is expensive and unreliable. We have also discovered that battery life (12 volt) may also be extended. ~ Does your system shut down due to cloud to cloud discharges like detection systems or is it prone to giving false alerts ("false positives")? No, our system does not shut down due to cloud to cloud discharges. Because we monitor the electrostatic atmosphere and compare all readings to a finite database, we seldom issue false warnings that result in out horns being activated. Do you think that all the professional golf tours and other clients would continue to utilize our products after-years of experience if we gave 3/29/2007 Thorguard.com 1..u_. /h1..~_~n~_rl ~~~ /+~~ ~n~ false-readings?

Overview Fire The automated system consists of early warning severe weather detection devices located on campus that are connected to air horns and strobe lights strategically placed throughout campus that can be used to alert the JMU community when atmospheric weather conditions are imminently likely to produce dangerous lightning strikes on or around the JMU campus. Facilities Safety Emergency Response lab When activated, warning devices currently located on top of Urec, Godwin Hall, at the Reservoir Street soccer fields and at the Public Safety building on South Main Street across from the Quad will sound a single fifteen second audible signal from their air horns and their strobe lights will begin to flash. Students, faculty, staff or visitors to the University who are outside should seek shelter immediately or follow any specific instructions given by on-site university officials at athletic or other special events and await the all clear signal. Hazardous fv'laterials Bloodborne Pathogens When the danger has passed the system will automatically sound three short consecutive five second audible signals indicating the all clear! The system may be used to alert campus of other non-weather related threats. Any tests of the system will always begin and end with an all clear signal! If further information regarding the danger or other special instructions is necessary, it may be broadcast on radio am 1610, the JMU radio broadcast system. Radiological Terrorism Remember: Continuity of Operations Plans System Activation - a singe 15 second blast of the air horns means danger! You should seek shelter immediately or follow the specific instructions given by on-site officials at athletic or other special events. Office Safety Theater Safety Long Stream of Air horns = danger! Crime All clear - consists of 3 consecutive - 5 second blasts of the air horns! Air horns (pause) Air horns (pause) Air horns = all clear! Field Trip Plan Student Handbook THOR GUARD OPERATIONAL TERMS V,ehicle Safety Polarity - THOR GUARD distinguishes between positive and negative polarity because during most storm conditions a negative electrostatic field of the same intensity as a positive field poses a much higher lightning hazard level. The intensity and shifts in polarity may be observed on the "Energy Level" LED bar. Negative polarity is displayed in red (3V), and Positive polarity is displayed in yellow (3V). Lighting and Safety Aviation Safety Safety Range - There are four (4) internal "Range" settings (Low, Medium, Medium High, High). The "Range" dictates the sensitivity of the system. A "Low" setting will make the system 50% less sensitive than a "High" setting. The prime consideration for selecting one setting or another is the amount of time required to move people to an area of safety following a "Red Alert" condition. Changing the "Range" setting will significantly change the operation of the THOR GUARD system and should only be done after consultation with a factory representative. Flood Media Releases off the Job LHL (Lightning Hazard Level) - This is the probability, from 0-90%, of a lightning strike http://www .j mu. edu/ safetyp I an/ emergresponse/ specificproced ures/weather/ earl ywamingalert. shtml 3/29/2007 Early Warning Alert System Page 2 of2 JfJiU Policies occurring within the defined area or Range (up to 15 miles) being monitored by the facility. The LHL will be the first and last indication that energy is present in the total area monitored. International ra m Safety DI (Dynamic Index) - The measurement of the electrical activity in the immediate area and the probability, from 0-90%, that if lightning strikes, it will strike nearby (2.5 mile radius). The Dr determines the warning level based on energy migration in your immediate area. A Dr of "3" (30% probability) will trigger a "Red Alert" condition which should provide a warning margin of eight (8) to twenty (20) minutes before the arrival of local lightning activity. If it does not then the "Range" may need adjustment. Risk Handbook Reference Material Index BOB (Bolt out of the Blue) - The condition in which very powerful lightning discharges may occur even with no clouds at all in the immediate area. A BOB may emanate from a weather front 10-20 miles away. When the system senses the conditions for this hazard the "Status" window will display a "BOB" message. This potential hazard should be treated as a "Red Alert" condition. Review and AD (Activity Detector) - The "Activity Detector" is an estimate of how much time before normal activities may resume. This number will be reset every time a major excursion of energy (i.e., Lightning strike) is recorded. The Activity Detector running time is a maximum of 10 minutes (unless reset) after which the system will return to the "All Clear" status. FCC (Field Collapse Count) - The FCC represents a sudden excursion of energy in the total area being monitored. Should a conductor be available, then visible lightning will be seen. On many occasions high amounts of energy may be exchanged without any visible indications of the exchange. The frequency of FCC's during a storm is indicative of the intensity of the storm. BUFFER - A record of storm activity may be saved to replay at a later date. The customer may choose the quantity of data to be saved to disk in the "Setup Menu." By selecting the "Replay" button you may replay any file containing past storm data. AP (Alarm Preset) - There are two (2) audible "Alarm Preset" levels that may be activated in the "Setup Menu." The "MUTE" button may be used to silence the alarm. "Energy Level": Red = The intensity of Negative (-) energy (Polarity) in the total area being monitored. Yellow = The Positive (+) energy (Polarity) in the same area. "All Clear": The Status Display window will normally show a green "All Clear" message when the system is sensing no local storm activity. "Caution": When the system first recognizes the presence of electrostatic energy within the total area being monitored, the white Caution message will be displayed. Although the primary purpose of this warning is to alert you of a change in surrounding conditions, fast moving storms can and will make this level of warning important to monitor. "Warning": The yellow "Warning" message indicates that electrical storm energy is migrating and shifting in your surrounding area. In some situations this represents enough of an increased safety threat to also activate the external alarms, if you have any. "Red Alert": In addition to indicating a potentially dangerous lightning condition, the Red Alert switch may be depressed to activate any external alarms or switches. It is definitely advisable to now curtail any outside activity! For further information on lightning, go to the National Lightning Safety Institute.

The first, the "Hyperstatic Sensor" assembly, constantly monitors the electrostatic field from its typical location on the top of a structure. The primary coverage area for this system is calculated using a radius of2.5 miles (5 miles in diameter). The total area being monitored, however, is a range that is adjustable to a maximum of approximately IS-miles in radius. The sensor communicates the data over special cable to the second element, the THOR GUARD computer console (model's LSO, LIOO & THORGUARDIAN). The computer evaluates the information fifty times every second within its integrated circuitry and produces two important potential lightning threat levels. The first is called the Lightning Hazard Level, or "LHL." The "LHL" represents the threat of lightning potential in the total area being monitored (Note: All THOR GUARD systems are accurate to Imv at IS-miles). For certain THOR GUARD models (LIOO & MAC) this is represented numerically, on a scale of one (1) to nine (9). The second important lightning threat level is called the Dynamic Index, or "01." The "DI" represents the lightning threat in the immediate area being monitored. This value is ascertained by relating the overall "LHL" level to local shifts in positive and negative energy. As above, the "DI" threat level is represented numerically, on a scale of one to nine. Other data processed within each system is lightning strike information (Field Collapse Count, or FCC), bolt out of the blue alerts, a 24 hour self-testing program, and an automatic reset timer measuring significant energy level exchanges during storms. All THOR GUARD console models evaluate basic storm data, developed by the sensor, in the same way. The major difference between selected models is in how the information is either interpreted, or displayed. Please refer to the individual product specification sheets. THOR GUARD L50 The THOR GUARD Model L50 Lightning Prediction System utilizes the same electrostatic analysis as our full display system, the THOR GUARD Model L I 00. For more than 20 years, our exclusive, prediction technology has proven that it can consistently and unfailingly predict the probability of a lightning http://www.golfcst.com/solutions/prediction.htm 3/29/2007 Prediction Page 2 of6 strike for the first time....every time. THOR GUARD L50 receives and evaluates the storm data from the Hyperstatic Sensor and then displays the potential threat of lightning by means of the four lights on the front panel (All Clear, Caution, Warning, Red Alert). The system has the flexibility to then activate a variety of different functions such as an external alarm system, or a sensitive equipment disconnection switching device. Almost as important as providing advance warning of a lightning hazard, the THOR GUARD L50 will also determine when safer conditions exist, indicating that a resumption of outside activity is advisable. THOR GUARD LIOO Using state of the art technology, the THOR GUARD LIOO provides easy to understand information on its display screen, both graphically and numerically, on the probability of a lightning strike specific to your location (not based upon the frequency and intensity of lightning strikes occurring miles away!). This can permit uninterrupted site operation or play even when lightning appears in the distance but your area of concern is safe. THOR GUARD not only anticipates the build up of a lightning potential in your geographic area of concern, but the systems notifies you of the potential for the very first strike or "Bolt out of the Blue". THOR GUARD LIOO receives and evaluates the storm data from the Hyperstatic Sensor and then displays the potential threat of lightning and a full color video display with on-screen self-help menu. Full color video dynamic display with on-screen self-help. Recorded verification of storm activity to review system operations. Lightning Hazard Level (LHL) measures the probability of a lightning strike within the predetermined area around your facility(adjustable for 3- to 15- mile range ). Dynamic Index (DI) measures the electrical activity in the immediate area and the probability that if lightning strikes, it will strike nearby. http://www.golfcst.com/solutions/prediction.htm 3/29/2007 Prediction Page 3 of6 Automatically self-tests every 24 hours. Multiple range sensitivity settings. Integrated alarm interface provides for automatic or manual external alarm activation at a predetermined hazard level. Easy monitoring of the magnitude and shifts oflocal energy activity to assist in making evaluations of dangerous and/or safe playing conditions. Range button allows for instant viewing of potential hazard beyond the standard, predetermined area being monitored Contact Us ., THORGUARDIAN The THORGUARDIAN is the first, totally integrated advance warning system for lightning. THOR GUARD has combined its state of the art lightning prediction technology with automatically activated air-horns and strobe lights, for single location applications. The entire system may be easily installed outdoors as a single unit. The sensor monitors energy as far away as 15 miles and evaluates the potential for lightning within an area of approximately two miles in radius. When the THORGUARDIAN senses a hazardous condition, the system automatically provides both audible and visual alerts. Under normal conditions the air-horns have a range of approximately 700 yards, in a 360' pattern. THOR GUARD lightning prediction computer with sensor. 360' audible air-horn warning package. Strobe light that remains active during "RED-ALERT" conditions (Conforms with Americans with Disability Act). Integrated, 7 day/24 hour timer for custom operation.

Additional enhancements such as remote reporting available upon request. Contact Us THOR GUARD L251 The THOR GUARD Model L251 Lightning Prediction System receives and evaluates energy data from the Hyperstatic Sensor and displays the hazard level in the "Status" window. When the probability of a lightning discharge exceeds a pre-selected level the L251 will automatically impulse an irrigation or equipment disconnection switch. Although small in size, the Model L251 has the same lightning prediction capabilities as all THOR GUARD products. It was designed to offer a low cost alternative to isolate lightning sensitive equipment from AC power prior to a lightning discharge. At a "Red Alert" level the L251 will energize an internal relay (Type C) through the "OUTPUT" port. When the threat of lightning has passed and the L251 has returned to an "All Clear" condition, the internal relay will automatically be de-energized. LED "STATUS" will display a "0" during "AIIClear" conditions. Three distinct warning levels of potential, electrical storm activity (Caution, Warning, Red Alert). Low, Medium & High levels of warning sensitivity range settings. Automatically self-tests itself every 24 hours (may also be manually tested). DB9 "Output" port to automatically switch irrigation equipment (cable supplied). Automatically monitors the potential risk for a dangerous "Bolt out of the Blue." Simple, quick and inexpensive installation process. Digital software control circuit that resets the system after power interruptions. http://www.golfcst.com/solutions/prediction.htm 3/29/2007 Prediction Page 5 of6 Back Contact Us DTN Offers Thor Guard Lightning Prediction System Did you know that a storm ten miles away can produce a lightning strike on your property?

This compact lightning detector is very reliable, yet small and sleek. This lightning detector is the newest high technology weather monitoring product available anywhere in the world. It is a hand-held instrument with an electronic system to detect the presence of lightning / thunderstorm activity occurring within 40 miles of your location. It uses patented technology (Full digital microprocessor insuring accuracy and reliability) to determine the distance to the detected stroke. The distances are indicated in four ranges: 0-3 miles (0-5 km), 3-8 miles (5-13 km), 8-20 miles (13-32 km) and 20-40 miles (32-64 km).
