3. CT Solar Lease Program How It Started Connecticut rebate program successful in implementation of several hundred residential systems- primarily on large homes in affluent neighborhoods- high upfront cost of solar leaves most homeowners out State desired loan program to help moderate to low income homeowners pay for balance of system cost After evaluation, lease was deemed to be the preferred financing vehicle In return for sponsorship and support, State was allowed to write some of the rules so that program met their stated objectives (qualifying income limits, etc.) 3

4. CT Solar Lease Program How it ended up $47MM program for approximately 1,000 systems over 3 years Homeowner chooses installer and equipment; negotiates price System Cost: typical system costs $47,000 Rebate: same as available to CT homeowners (approx. 50%) Term: Initial lease term is 15 years, optional 5 year extension No Money Down required from homeowner Lease payment of approximately $120/month End of 15 years: Extend lease for another 5 years FMV purchase Return to leasing company 4

5. CT Solar Lease Program How it Works State fund provides rebate and support for debt Gemstone manages leasing company and underlying assets for investor and utilizes AFC First, the third party administrator (TPA), for program administrator/lender/servicing functions US Bank provides equity Leasing allows: Immediate use of ITC and effective use of other tax benefits Aggregation and diversification for Consumer credit quality (portfolio loans) Effective monetization of renewable energy credits Asset management, monitoring and state reporting 5

6. Choose Your Partners Carefully Third party administration is key In CT program, Gemstone splits operational and management duties with AFC. Gemstone manages leasing company including asset management and system relocations, REC aggregation and sales, accounting and tax functions AFC provides installer training, consumer credit underwriting, lease origination, servicing, collections and consumer protection compliance A good manager and TPA team is vital to create attractive terms and economics for all parties. Poor credit underwriting drives up program costs- collections, potential ITC recapture, system relocations, etc. Set Sponsor (eg: State) objectives and expectations carefully What is best for the homeowner might not meet IRS requirements Use professionals (legal, accounting, etc.) with experience in leasing, tax credits and related structures Need to evaluate many alternatives to meet needs of the public and private sector interests. For example, all leverage vs. no leverage structures and partnership flips vs. master lease structure 6

7. Credit Quality Will Rule Managing credit quality drives down costs; increases competiveness; and reduces risk to all parties Credit quality is much more than just a good credit score. An experienced TPA can achieve far better results from a pool of sub-700 credit scores than a pool of higher scores Strong initial underwriting with personal contact with each lessee who thoroughly understands details and importance of transaction before a lease is signed Strong credit profile – Leasing collateral generates its own cash flow to support the lease payment – pay LC and reap energy profit or pay Utility more! Long term investment vs. short term savings decision Lease allows effective fix of electric rates for 15-20 years but might not always be lower than offset utility cost in year 1 Avoid investing $50,000 on a roof where the primary motivation is to save $10-20 on next months utility costs 7

8. Credit Quality Will Rule(Cont.) Indicative default and charge-off rates provided by AFC on unsecured energy efficiency loan portfolio 8 2008 Update National Avg. : 4.22% AFC :.83%

9. Is Third Party Ownership Still Viable? Lifting ITC cap does little to help typical middle to lower income family Still need to write a big check for balance of system cost and wait for many state rebates and tax refund Home equity loan and mortgage refinancing market on thin ice Most homeowners not equipped to manage proper monetization of incentives such as RECs and perform required reporting and verifications Sale of home within 5 years could create thorny tax recapture issues Third party ownership simplifies contractor sales process Simple monthly cost can easily be compared to utility savings Removes key objections and obstacles (no money down) Expands market. Moderate income homeowners who were lookers can now be lessees 9

10. Whats the Latest? From true start at end 2008, CT Solar has approved rebates and signed leases for nearly 15% of the total portfolio and a pipeline (post credit/pre rebate) over 25%. Installation process in CT is takes nearly 140 days vs. other states like CA In discussions with other eastern states for both a general product offering and specialized program; 10
