On January 11, 2016, Spire Corporation (the “Company”) entered into an Asset Purchase Agreement (the “Purchase Agreement”) with Eternal Sun USA, LLC (“Buyer”) pursuant to which Buyer agreed to acquire substantially all of the assets of the Company's Sun Simulator technology line (the “Sun Simulator Business”) and assume certain liabilities associated with such purchased assets as set forth in the Purchase Agreement (collectively, the “Transaction”). The Transaction was entered into in connection with the Company’s continuing restructuring efforts, pursuant to which the Company will focus on its retained turnkey manufacturing line business. The aggregate purchase price for the Sun Simulator Business was $1.5 million plus the assumed liabilities.

The Purchase Agreement also includes a five-year commitment of the Company not to compete with Buyer with respect to the Sun Simulator Business (provided, however, that the Company may from time to time sell certain simulator equipment as part of its retained business). The Purchase Agreement also contains customary representations and warranties, post-closing covenants and mutual indemnification obligations for, among other things, inaccuracy or breach of any representation or warranty in the Purchase Agreement and any breach or non-fulfillment of any covenant contained in the Purchase Agreement and related transaction agreements or certificates.

This summary description of the Purchase Agreement is qualified in its entirety by reference to the actual Purchase Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
