BRYANT PARK CAPITAL EMERGING ENERGY COMPANY UPDATE

MERGERS & ACQUISITIONS CAPITAL RAISING ADVISORY VALUATION

MARKET VIEW: In this issue of Bryant Park Capital’s Emerging Energy Company Inside this issue: Update, we highlight a notable trend of capital formation in the power sector with the Energy Trends p.1 emerging asset class of “YieldCos”, i.e. entities which have highly contracted cash flows from Power Trends p.3 which dividends and growth are funded. Since mid-2013, six companies have gone public in M&A p.5 North America via this structure, due to the increased market valuation of yield/income oriented equities. For large independent power producers and utilities with portfolios of Private Placements p.7 generating assets, YieldCos enable the separation of the contracted power assets from the Public Comps p.8 merchant (uncontracted) assets, and thereby the potential to unlock shareholder value by

garnering higher valuation multiples owing to improved long-term cash flow visibility. From the debt perspective, we continue to see companies continuing to search for and find efficient capitalization techniques in a market starved for yield; by way of example, asset backed securitizations. In July 2014, SolarCity priced its third solar ABS, a $201.5 million note, which was priced very positively at 4.026% for the $160 million Class A tranche and 5.45% for the $41.5 million Class B tranche, for a weighted average rate of 4.32%. Both the equity and debt markets seem to continue to be in favor of energy/power capital issuers as the Fed appears committed to keep interest rates low for a considerable period of time.

ENERGY TRENDS

MARKET OBSERVATIONS: ■ Crude Oil: □ U.S. production averaged 8.6 million bbl/d, the highest monthly production since July 1986. □ Production is expected to continue to grow in the Bakken, Eagle Ford, and Permian regions through 2015, fueling an increase in supply □ For the first time in 14 months, Brent Spot Prices fell outside the range of $107/bbl and $112/bbl, due in part to weakening global demand and increased Libyan oil exports Oil Prices vs. Gas Prices

ENERGY TRENDS

■ The Henry Hub average natural gas spot price was $4.59/MMBtu in June, decreasing 15% to $3.91/MMBtu in August. Henry Hub natural gas prices are projected to average $4.46/MMBtu and $3.87/MMBtu in 2014 and 2015, respectively. ■ Since the beginning of 2014, oil has traded in a band between $90 and $110 per barrel (WTI), and more recently has been in the lower to middle $90 range. ■ Due to falling crude oil prices, U.S. regular gasoline retail prices continue to fall; $3.49/gal was the average price for August, which was 12 cents and 21 cents below the average for July and June, respectively. Prices are estimated to continue to fall to $3.18/gal in December, making the average for 2014 $3.46/gal – five cents below the 2013 average. □ U.S. Number 2 Diesel retail prices fell from an average of $3.91/gal in June to $3.84/gal in August. ■ U.S. oil and natural gas wells are continuing to see steady increases in productivity in many basins due to the increase in precision and efficiency of horizontal drilling and hydraulic fracturing in the extraction process. ■ Over the last few years, five of the six main U.S. shale basins (Bakken, Eagle Ford, Haynesville, Marcellus, Niobrara and Permian) have seen an overall increase in oil and natural gas production per rig. □ Permian is expected to have the largest increase in production of oil per rig from September to October and Haynesville is expected to have the largest increase in production of natural gas per rig from September to October. ■ Shale Oil □ Since 2009, Eagle Ford, Permian and Bakken basins have witnessed the largest increase month-over-month of barrels per day, producing on average 31 thousand, 39 thousand and 27 thousand barrels per day, respectively. ■ Shale Gas □ The Marcellus Shale basin exceeded natural gas production of 15 billion cf/d, the first time ever recorded; production rate is expected to increase by 247 million cf/d due to the impact of new wells. □ The Marcellus region accounts for roughly 40% of all US shale gas production.

POWER TRENDS

MARKET OBSERVATIONS: ■ Year to date through June, the US generated 2 billion mWh of electricity. This is an increase over the same period in 2013, when 1.96 billion mWh were generated. Coal was the biggest generator, generating 806 million mWh followed by natural gas, which created 504 million mWh. ■ For the first half of 2014, retail residential electricity prices increased to an average of 12.3 cents/kWh or 3.2% from the same period last year; this is the highest year-over-year increase for the first half of the year since the beginning of 2009. □ The average price of electricity rose in all areas of the country except for the Pacific Census Division (excluding Hawaii and Alaska); this is due to the $35 California Climate Credit that most customers received; New England experienced the largest jump with an increase of 11.8% ■ 4,350 MW of new utility scale generating capacity came online in the first half of 2014. Natural gas plants accounted for more than half, solar plants for over a quarter, and wind plants one-sixth. This new generating capacity is 40% less than the same period last year, while solar increased by roughly 70% and wind nearly doubled from the same period. ■ Florida and California added the most utility scale generating capacity, creating approximately 1,210 MW and approximately 1,100 MW respectively; and Texas followed, creating a combined 1,000 MW U.S. Average Levelized Cost of Electricity (2012 $/MWh) for Plants Entering Service in 2019

POWER TRENDS

■ Yield Cos □ YieldCos are increasingly populating in clean energy universe; six companies have gone public since July 2013 □ In July, SunEdison (Nasdaq: SUNE) took TerraForm Power (Nasdaq: TERP), its holding company of operating solar PV projects, public by spinning it off and creating a YieldCo. The IPO raised approximately $530 million. ■ Coal Fired □ No new coal plants went live in the first half of 2014; the only plants planned for 2014 are the Kemper integrated gasification combined-cycle (IGCC) in Mississippi and a small conventional steam coal in North Dakota. □ This reflects the pressure coal fired power plants are experiencing from the natural gas spark spread and increased regulatory demands □ The U.S. produced 242 MMst of coal in the first quarter of 2014 ■ Solar □ 1,133 MW of solar PV installations occurred during Q2; this is an increase of 21% over the same quarter in 2013; solar accounted for 53% of the total capacity of all new electric generating capacity in Q2 and was the fourth- largest quarter for solar installations. □ California installed the most MW during Q2, 672 MW; followed by Massachusetts and New Mexico which installed 112 MW and 72 MW, respectively. □ Over half a million homeowners and commercial customers installed solar PV in the first half of 2014. ■ Wind □ Wind generation increased to more than 30% of total renewable generation from 3% between 2003 and 2013 □ EIA estimates that wind power capacity will be increasing substantially over the next several years with electricity generated by wind projected to reach 4.5% of all electricity generation by 2015. Wind power capacity is anticipated to grow by 8.6% and 13.9% in 2014 and 2015, respectively. □ In the first half of 2014, 675 MW of utility-scale wind capacity was added, more than double the same period in 2013 (329 MW) □ California added the most at 228 MW followed by Nebraska, Michigan and Minnesota. ■ Other Renewables □ 2014 is expected to be the first year when annual non-hydro generation surpasses annual hydropower generation; by 2040 non-hydro is expected to provide twice as much generation as hydro power. □ The increase in popularity in wind and solar as well as declining costs of technology have contributed to the increase in non-hydro renewable generation □ In 2015 it is estimated that electric power and heat renewables generation will increase by 3.4% from the amount estimated in 2014. □ Non-hydropower renewables are projected to increase by 4.0% with hydropower increasing by 2.2% in 2015.
