Background

a.                                       Simultaneously with the execution of this Agreement, STR Holdings, Inc., a Delaware corporation and the parent corporation of STR (“Holdings”), and Zhenfa entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”), pursuant to which Holdings has agreed to sell, and Zhen Fa New Energy (U.S.) Co., Ltd., an Affiliate of Zhenfa, has agreed to purchase, shares of common stock of Holdings (the “Purchased Shares”) constituting a majority interest in the common stock of Holdings in accordance with the terms and conditions set forth therein (such purchase and sale to be referred to herein as the “Transaction”).

b.                                       Zhenfa and its Affiliates (the “Zhenfa Group”) specialize in photovoltaic system designs, supplying of materials, contracting and project finance, including the engineering, procurement and construction (“EPC”) of integrated solar projects in China and other countries.

c.                                        In connection with the sale of the Purchased Shares, the Parties desire to establish a strategic relationship whereby the Zhenfa Group would, among other things, assist STR and its Affiliates (collectively, the “Company”) in the marketing, sales and distribution of the Company’s encapsulant products to Chinese solar module manufacturers.

d.                                       Upon the closing of the Transaction, the Zhenfa Group and the Company wish to work together to expand the Company’s business in accordance with the terms and conditions set forth herein.

NOW, THEREFORE, subject to the foregoing, the mutual covenants and agreements set forth herein, and other consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereby agree as follows:

1.                                       Effective Date.

As set forth in the Stock Purchase Agreement, the closing of the Transaction (the “Transaction Closing Date”) will be subject to certain conditions to closing, including the receipt by the Company of stockholder approval of the Transaction.  This Agreement shall become automatically effective, without any further action by either Party, upon the Transaction Closing Date.  Thereafter this Agreement shall

1

continue until terminated pursuant to Section 5 hereof.  If the Transaction Closing Date does not occur, this Agreement shall become void ab initio and have no force and effect.

2.                                       Zhenfa Group Assistance.

The Zhenfa Group hereby agrees, from and after the Transaction Closing Date, and for so long as this Agreement shall remain in effect (the “Term”), as follows:

(b)                                 Manufacturing Facilities. The Zhenfa Group agrees to provide the Company with an option to lease a manufacturing facility of not less than 10,000 square meters located in either Wuxi, Jiangsu Province, China or Zhangjiangang, Jiangsu Province, China, as mutually agreed by the Parties, in broom clean, move-in condition rent free for a period of at least five (5) years.  The Company may elect to exercise this option by providing written notice to the Zhenfa Group at any time within two (2) years of the Transaction Closing Date.  If the Company exercises this option and wishes to remain after the initial five (5) year term, the Zhenfa Group agrees to provide an option to extend the lease of such facility for a second term of five (5) years with rent at a rate no higher than fifty (50%) of the fair rental value for such facility.  For the avoidance of doubt, the option to lease set forth in this Section 2(b) shall not survive the termination of this Agreement; provided, however, that any lease entered into pursuant to this Section 2(b) shall be governed by the terms thereof and survive the termination of this Agreement in accordance with the terms thereof.
