This Agreement may be terminated, and the transactions contemplated hereby may be abandoned, by written notice promptly given to the other parties hereto, at any time prior to the Closing by the Company, on the one hand, or if the Closing shall not have occurred on or prior to June 5, 2017 by the Purchaser on the other; provided that the Company or the Purchaser, as the case may be, shall not be entitled to terminate this Agreement pursuant to this Section 6 if the failure of Closing to occur on or prior to such dates results primarily from such party itself having materially breached any representation, warranty or covenant contained in this Agreement.
