The price paid by Buyer for all Products through December 31, 2009 will be based on a five
percent (5%) discount off of Fair Market Wholesale Value for comparable commercially available PV modules sold within the same target market segment. Where no direct comparable product exists, prices will be linearly prorated based on the
square meter power efficiency for similarly rated products within that target market segment.

Fair Market Value (FMV) of comparable Silicon solar cell or
other thin film modules, based on long term contract pricing will be agreed to in writing during Quarterly Product Projection meetings beginning Q1 2008. Failure to agree to FMV will be subject to the conditions listed in paragraph 4.2

For 2010-2011 Seller and Buyer shall in good faith negotiate further pricing by Buyer of Product. The parties agree to fix a price by mutual agreement for every six-month delivery period during the years 2010 and 2011
by the 1stof November each year, respectively, unless mutually agreed otherwise.

4.2 Failure to Modify Price

If no agreement on price is reached through the
parties good faith efforts within a thirty day period from the Quarterly Product Projection meetings, and price and volume will result in net loss to either party as established by documented costs, then the parties shall renegotiate or, if
necessary, terminate this Agreement by written notice. If this Agreement is terminated under these conditions the Seller agrees to continue sales for six months beyond their existing obligations or approximately 12 months from the last bi-annual
meeting, whichever is sooner, at the prices and projected quantities last agreed upon for the previous six-month period, at which

the seller at the last agreed upon price and conditions.
