On January 5, 2015, EMCORE Corporation, a New Jersey corporation (the “Company”), announced that it completed the sale of certain assets and certain liabilities, primarily related to or used in the Company’s telecommunications business (the “Digital Products Sale”) to NeoPhotonics Corporation, a Delaware corporation (“NeoPhotonics”), for an aggregate purchase price of $17,500,000, subject to certain adjustments described below (the “Purchase Price”), consisting of (i) $1.5 million in cash and (ii) a promissory note from NeoPhotonics in the principal amount of $16 million (the “Promissory Note”). The Promissory Note bears interest of 5% per annum for the first year and 13% per annum for the second year, payable semi-annually in cash, and matures two years from the closing of the Digital Products Sale.  In addition, the Promissory Note is subject to prepayment under certain circumstances and is secured by certain of the assets to be sold pursuant to the Digital Products Sale. The Purchased Assets include fixed assets and intellectual property for the ITLA, micro-ITLA, T-TOSA and T-XFP product lines and inventory for the ITLA and micro-ITLA product lines within the Company’s telecommunications business.   Pursuant to the asset purchase agreement, dated October 22, 2014, as amended by Amendment No. 1 dated January 2, 2015, by and between the Company and NeoPhotonics (the “Digital Products Agreement”), the Purchase Price is subject to certain adjustments for inventory, net accounts receivable and pre-closing revenues, and the principal amount due under the Promissory Note will be increased or decreased, as applicable, by an amount corresponding to any such adjustment.
