2. WebGen’s Mission Minimize Energy Consumption While Maximizing Comfort By Integrating • Industry Expertise And Knowledge of Building Systems • With • Established Artificial Intelligence Control Technology

3. Hobbs Brook Management Trizec Properties Bank of America American Ventures NYSERDA, State of New York State of California, DGS University of Miami, Florida Fidelity Investments Representative Customers • 400 + Buildings Contracted

4. WebGen’s IUE™ Technology IUE™ EmploysProven Neural Networking Technology Based on Building Management ‘Best Practices’ To Regulate And Control Energy Usage In Real Time.

5. The Result • 15-25% Energy Use Reduction • With Minimal Impact on Tenant Comfort • Through • Always-Active Permanent Load Reduction • Full-Time Peak Load Management (Avoidance & Reduction) • Curtailment & Sale Back to Grid Authority • Virtual Meter Aggregation, D-Gen & Procurement

6. IUE Allows Building Managers To • Monitor Consumption ofEnergy Consuming Devices & Meters • Aggregate Data for Buildings, Portfolios, Divisions, etc. • Correlate Consumption Data with Energy Prices, Occupancy, Current Internal and External Environmental Conditions and Real-Time Satellite Weather Forecasts • Continuously “Learn” Device Consumption Patterns and Their Reactions to Change • Forecast Usage & Execute Smart Conservation Strategies • Intelligently Control Devices • Optimize EquipmentSettings • Demonstrate, Report & Account for Results in Real Time

7. IUE Technology Enhances Building Automation Systems

18. Bank of America Energy Curtailment For The California Energy Commission June 27, 2002

19. California Energy Commission Pilot Test • On June 27, 2002, WebGen Systems Intelligent Use of Energy product curtailed 2 Megawatts of power, in 78 Bank of America properties, within the state of California. • The total load of the 78 properties was approximately 9 Megawatts • The time duration was four hours. The test commenced at 2:00 PM, and completed at 6:00 PM, PDST • The following slides display the demand trends for Northern & Southern California, and the aggregate for the pilot test.

21. Financials and Payback Full IUE™ System Cost Summary • Net Reduction in Energy Spend • 10 -15% after payment of all fees, shared savings & revenues • One-Time Installation Cost • $.04 - $.25 per gross sq ft (higher in small buildings) • Annual Maintenance Fee • $.09 per gross square foot • WebGen Share of Energy Savings • 25% of reduction below baseline energy spend • WebGen Share of Capacity & Energy Sold • 50% of all new ‘demand responsiveness’ revenues generated

22. Financials and PaybackSavings & Revenues( $ Per Square Foot) Annual Energy Savings on $2.50 energy spend* $0.44 • 10.0% Permanent Load Reduction $0.25 • 7.5% Peak Load Avoidance & Diversification $0.19 Annual Capacity & Energy Revenues** $0.17 • Capacity (.75 W/sq.ft. @ $0.08/W) $0.06 • Energy (.75 W/sq.ft. @ $0.15/kWh) $0.11 Total Annual Savings & Revenues $0.61 *Assumes constant baseline data. Any changes in weather patterns, building occupancy, plug load, lighting load, capital projects will impact savings. *WebGen does not participate in savings resulting from reduced maintenance, lower staff costs, energy-efficient capital projects, etc.. **Where applicable, assumes sale of Capacity @ $80,000/MWY and Energy @ $500/MWH (300 hours)

23. Financials and Payback Savings & Revenues( $ Per Square Foot) Total Annual Savings & Incremental Revenues $0.610 Less: WebGen Maintenance Fee @ $.09/sq. ft. $0.090 Available for Distribution $0.520 WebGen Share of Energy Savings @ 25% of $.44 $0.110 WebGen Share of Revenues @ 50% of $.17 $0.085 Total Customer Share of Savings & Revenues $0.325 Annual Net Savings to Customer $0.325 Total Customer Energy Cost Reduction = 13.0% Customer Payback on Invested Capital* +/-12 months Minimum Energy Savings to Break Even = 4.7% • *Assumes $.08/ sq. ft. installation cost, amortized over 3 years, and no mitigating ISO funds are available.
