The Merger Agreement contains certain termination rights for both the Company and the Parent Entities, and provides that, upon termination of the Merger Agreement by the Company or Parent upon specified conditions, the Company may be required to pay the Parent a termination fee of either $10,000 or $15,000, depending upon the reason for and timing of the termination, and any costs of collection. In addition, subject to certain exceptions and limitations, either party may terminate the Merger Agreement if the Merger is not consummated by August 16, 2017, subject to possible extension until September 29, 2017 to allow for the completion of certain regulatory approvals or if the Shareholder Approval has not yet been obtained. The Merger Agreement also contains a “go-shop” provision that, in general, allows the Company to initiate, solicit and encourage, and engage in discussions or negotiations with respect to, an acquisition proposal for the 30-day period after execution of the Merger Agreement. The Company may continue discussions after the go-shop period with any party who made an acquisition proposal during the go-shop period that the Company determines in good faith is or could reasonably be expected to result in a superior proposal. Following the expiration of the go-shop period, the Company will be subject to a customary “no-shop” provision. The Transaction, if it were to be completed, could further limit the Company’s utilization of accumulated net operating losses, for federal income tax purposes. The Company has not performed a Section 382 study to determine if its net operating loss carryforwards could be adversely impacted by the Transaction.
