In the event the Company spins off a subsidiary by distributing to the shareholders of the Company as a dividend or otherwise the stock of the subsidiary, the Company shall reserve for the life of this Warrant, shares of the subsidiary to be delivered to the Holders of the Warrants upon exercise to the same extent as if they were owners of record of the Warrant Shares on the record date for payment of the shares of the subsidiary.

The Company shall pay all expenses (with the exception of any selling commissions relating to the sale of the Warrant Shares which shall be paid by the sellers thereof) of any such registration statement.

(C) Keep effective such registration statement until the first of the following events occur: (i) 12 months have elapsed after the effective date of such registration statement or (ii) all of the registered Warrant Shares issued by the Company either before or after the effective date of such registration statement has been publicly sold under such registration statement. (5) The Holder(s) shall supply such information as the Company may reasonably require from such Holder(s), or any underwriter for any of them, for inclusion in such registration statement or post effective amendment. (6) The Company's agreements with respect to the Warrant Shares in this Section will continue in effect regardless of the exercise or surrender of this Warrant. (7) If the Company registers the Warrants under (g)(2) above, solely to accommodate the registration of the Warrant Shares, the Holder(s) agree not to sell or otherwise transfer the Warrants pursuant to the Registration Statement for a period of 24 months after the effective date. Such lock-up shall not extend to the Warrant Shares purchased on exercise of the Warrants.
