3. Clean Energy Clean Energy is the leading provider of natural gas as a transportation fuel. We provide both compressed natural gas (CNG) and liquefied natural gas (LNG) to companies that operate fleets of taxis, transit buses, government vehicles, trucks, buses, and garbage trucks.Clean Energy is the leading provider of natural gas as a transportation fuel.

5. Utilizes existing NG distribution Compressed and Stored on-site Dispensed in Fast Fill or Time Fill Sold in GGE = 125,000 Btu Sold in DGE = 139,000 Btu Stored as a gaseous fuel onboard Similar fuel economy to petrol Compressed Natural Gas

6. Produced at liquefaction facility Trucked to fueling station Stored on-site Sold in DGE = 139,000 Btu Stored as a liquid onboard Similar fuel economy to diesel Liquefied Natural Gas

8. Natural Gas for Transportation I think the reason natural gas has been so successful is it makes business sense. It�s cheaper, cleaner, and domestically available.

10. Fuel Savings Federal policies in place in combination with the inherent fuel savings achieved through using NG help make NGVs very affordable The federal 2005 Energy Bill and Highway bills offer significant tax credits for vehicle purchases, stations, and fuel These are Tax Credits not tax deductions Bottom line financial impact Up to $32,000 per vehicle for Heavy-duty vehicles Up to $30,000 tax credit for large stations Up to $4,000 per vehicle for Light-duty vehicles Up to $1,000 for home refueling These are examples of how policies can be created to stimulate penetration of alternative fuels and bring them to a point of sustainability Using a Refuse Truck as an example, the tax credit reduces the incremental cost of a NG refuse truck to $6,000 but provides the operator with savings of $9,344 per year in fuel and operational costs. As you can see, savings vary based on application, but no matter what the application, savings are realized.

12. NG is the Cleanest Vehicle Fuel Available! NGVs Reduce Greenhouse Gases: 31% for Light Duty Vehicles 23% for Medium / Heavy-Duty Vehicles 2008 Honda Civic GX rated AT-PZEV: Greenest Car on the Planet for 2006-2008 Only Car Cleaner than the Prius Heavy Duty Vehicles Certified to 2010 EPA Emissions Standard: Cleanest Heavy Duty Technology 83% reduction in smog forming NOx 90% noise reduction In addition to having a number of manufacturers in the market, the cleanliness of natural gas has made our vehicles some of the cleanest, if not the cleanest, vehicles on our roads today. Vehicles manufactured include the Honda Civic GX, currently rated by ACEEE as the �greenest car of 2007� and Westport which plans to offer a 2010 US EPA compliant heavy-duty engine by may of this year. This is an achievement that places natural gas as the engine of choice for areas that face significant pollution issues, particularly when today�s diesels struggle to achieve today�s standards. Other manufacturers in the US Market include: LDV: Baytech (Ford E-350/450), BAF Technologies (Crown Victoria), and perhaps Standard Taxi. Vehicles achieve SULEV standards or better M/HDV: Cummins, John Deere, Emission Solutions While U.S. OEMs (GM,Ford,Chrysler) have abandoned the U.S. market � they are making and selling light-duty products in Europe 4 million NGVs in world today growing 20% per year We believe that with the right policy signals, more NGV product will come to US and CA markets. Foreign Markets players include: Daimler Chrysler Motors: Mercedes E200 NGT; Mercedes NGT Sprinter; Mercedes Econic (HDT), Mercedes Vito (van) and Mervedes E00 NGT (DC testing both in the market) General Motors: Opel Zafira; Opel Astra Caravan; Opel Combo, Isuzu Transir bus; Isuzu Elf truck Ford Motor Company: Focus C-max CNG; Transit Skap; Transit Pickup; Volvo V70, S60, S80 CNG (may be discontinued) Toyota Motor: Crown; Corolla Van; Dyna/Toyoace truck Nissan: Cedric/ Gloria sedan; AD Van; Nissan Transir bus There are also many light-duty car and truck models made by Fiat, Volkswagen, Renault, Peugeot, Citroen, Ivec, Scania, Mitsubishi, Tata among others.

14. Fortunately for the United States and North America, we are rich in natural gas. Whenever the issue of NGVs comes up the issue of available supply is one of the first questions asked U.S. natural gas 87% of gas used in U.S. is from U.S. sources 11% from Canada 3% from overseas Issue of �reserves� vs �resources� [reserves = inventory of beef in supermarket � resources = estimates for cattle in fields] As we look at petroleum diversity we are considering geographic/geopolitical diversity Need to view geographic/geopolitical diversity also for natural gas Natural gas use in Calif./U.S. projected to grow just to serve traditional markets and the potential for biogas will add to current domestic supply US may increase LNG imports form overseas, but our company is not dependent upon it as we are building our LNG supply domestically. Price Increasing natural gas imports [from 2% to 5-10% potentially} still far from problem of being 60+% dependent on petroleum imports Fortunately for the United States and North America, we are rich in natural gas.
