The Phase I report states the result of the wind and solar site surveys and provides recommendations for a suitable wind turbine capable of surviving gale force winds and an appropriate photovoltaic panel capable of surviving the downpour of 1.5” diameter hailstones. The Phase I report, delivered June 1. 2008, also provided a preliminary layout of the solar and wind energy assets of the roof. The findings of the report showed that: • the top of the new OMRF research tower could only provide a fraction of the total energy required by the building. The exact amount was equal to 2.5% of the future building’s electrical load. Site visits in July to the OMRF revealed that many other roof-top opportunities exist on adjacent buildings to power the facility with photo-voltaic (PV) panels. • An analysis of wind and solar PV, comparing cost of equipment and delivery of en-ergy, showed that PV was slightly more cost effective on a $ per watt basis. • On July 2008 projections from the Phoenix Design Group, the electrical engineers of record, indicated that the proposed OMRF Research tower would consume 4,911,317 Kwhrs of electricity in one year. It was decided that for the building to achieve Platinum LEED rating, the building would have to produce 12.5 % or 613,915 kWhrs/year of its electrical energy from solar and wind energy. On September 2008, P+W finalized the roof plan which is now the basis of this Phase II report. • The current designed output from solar and wind of the OMRF research tower is 157,936 kWhr/year. What is required is the additional production of 455,979 kWhr/year. • In order to produce 12.5% of the buildings electrical energy we will need an addi-tional 350 kW of photovoltaic panels to the surrounding buildings. • Finally, extensive financial modeling has started to attract an investor and partner to finance the renewable energy components of the building. This is tricky because the cost of electricity in Oklahoma, made from coal, is relatively inexpensive. Synergy California L.P. 12-30-2008 3 Oklahoma Medical Research Foundation: (OMRF) Phase 2 Report: 1.1 The OMRF tower and the renewable energy systems. The roof of the tower creates opportunities for the placement of 24 wind-turbines. These are located within trellises which act to accelerate the speed of the wind. Photovoltaic panels are placed above the trellises and are facing south at a 20 degree angle. PV panels are also mounted on the penthouse and on the roof areas. Buildings in front and the rear will also be utilized as PV collector mounts. Together these will contribute to providing 12.5% of the building’s energy from renewable en-ergy. Synergy California L.P. 12-30-2008 4 Oklahoma Medical Research Foundation: (OMRF) Phase 2 Report: 2.0 Building Integrated Wind Energy System. (BIWE) The wind turbines are spaced 1.5 rotor diameters apart within the trellises. This makes it unlikely that the turbulence of one will overshadow the other. The rotors are also spaced 6 rotors apart, downwind. The elevation drawing shows the orientation facing south. This is also the direction of the prevailing winds from the south and north. On top of the trellises are positioned the photovoltaic panels facing south at a 20 degree angle.

Note: There may be days where the wind turbines are working through the night because of storm conditions. This represents an energy bonus situation. Likewise there may be overcast days that limit the output of the PV system. Net metering contracts with Oklahoma Gas and Electricity are over a period of one year. All systems are monitored to resolve the NET GAIN over the period of one year Synergy California L.P. 12-30-2008 28 Oklahoma Medical Research Foundation: (OMRF) Phase 2 Report: 4.1 Power Purchase agreements with OG&E. The Proforma has been completed now that we have received all estimates of the rate structure from Oklahoma Gas and Electric. We are receiving hard quotes from Solar PV and Wind turbine suppliers. We are also determining precise Federal Tax Credits, Production Tax credits, Invest-ment Tax credits, Renewable Energy Credits and Rapid Depreciation Allowances as they apply to Oklahoma. The recent $700B Economic Bailout Bill provided provisions that extended the Federal Solar tax credit out to the year 2015. Likewise the production tax credit of 15% was reinstated for wind energy systems. These final quotes can be shown to Energy Service companies who may finance the overall renewable energy development. As a non-profit corporation OMRF can’t take advantage of the solar and wind energy tax credits. We are having discussions with OG&E, the Oklahoma Gas & Electric com-pany to partner and become an investor in the renewable energy assets of the building(s) We expect to have a final Proforma completed by February 1, 2009 For further information contact: Reinhold Ziegler, R.E.
