Solar PV Is Evolving From A High Profit Specialty Market To A Commodity Market

• Solar “Glut” is putting pricing pressure on solar factories, creating a need for solar producers to reduce their costs while increasing output

• New factories with lower production and CapEx costs are under development around the world• New factories need high production at low cost to survive• High cost factories are closing• Commodity focused production-strategy needed for solar factories

to thrive

CONFIDENTIAL 3

Baker Solar Was Founded by M.E. Baker in 2008 to Help Drive Down Solar Factory & Production Costs

• M.E. Baker Company has been a world leader in high-volume, wet-process equipment for more than 30 years• Baker produces efficient, productive tools for producing high-end

printed-circuit-boards, flexible circuits, and electro-formed components

• Baker’s technology base providing high-volume precision wet process tools can be utilized by solar factories who traditionally have purchased high-cost, lower-volume semiconductor-derived tools

• Baker has a deep legacy satisfying challenging applications at leading companies like 3M, Northrop-Grumman, Lockheed-Martin, Sanmina-SCI, Amphenol, Parlex (now Johnson Electric), and others.

• Baker Solar division was founded by Baker in 2008 to take existing technologies to photovoltaic (PV) solar markets, where they will improve costs and throughput in all types of PV • Silicon wafer & ingot manufacturing

Why Solar: Photovoltaic Electricity Is Nearing The End Of The Beginning• Solar electricity is entering a growth phase due to strong

economics• Photovoltaic (PV) electricity is well understood, 50+ year history• Long-term cost improvement trends are driving down the cost of solar• Solar electricity is now competitive with utilities in some markets• Government programs are also helping drive demand

• U.S. Investment tax credits offset 30% of system cost, program extended thru 2016

• Net-metering / feed-in-tariffs allow consumers to sell excess electricity back to utility

• Germany & California pay above market rates for excess electricity

• Ongoing cost improvement programs will soon make solar economic in more places

Prices Have Declined With Volume, Fueling More Growth

Solar Electricity Will Soon Cost Less Than Utility Power

Why Solar Processing Equipment: “Pick & Shovel” Vendors Thrive In Fast Growing Markets

• Strong demand for PV-electricity systems has created a large and growing market for solar processing equipment

• Currently the solar market supports hundreds of factories, but only a handful of equipment producers for key process steps• Processing equipment has higher

barriers to entry than cell and panel production

• As market matures weaker factories will disappear and survivors will need new & improved equipment to compete

• Companies with the know-how to increase factory output and productivity have built large, profitable businesses in short timeframes• Equipment companies are

profitable, delivering EBITDA typically between 10% and 20% of sales

• A ready market has developed for selling these growing equipment companies at strong valuations
