Call Option The Company shall have the option to "call" the Warrants (the "Warrant Call"), in accordance with and governed by the following: (a) The Company shall exercise the Warrant Call by giving to each Warrant Holder a written notice of call (the "Call Notice") during the period in which the Warrant Call may be exercised. (b) The Company's right to exercise the Warrant Call shall commence with the actual effective date of the registration statement described in Section 10.1(iv) of the Subscription Agreement and thereafter, shall be coterminous with the exercise period of the Warrants for a maximum of 50% of the Common Stock issuable upon the exercise of this Warrant (the "Warrant Shares"), provided, that the registration statement is effective at the date the Call Notice is given and through the period ending 14 business days thereafter. In no event may the Company exercise the Warrant Call at any time unless the Warrant Shares to be delivered upon exercise of the Warrant, will be upon delivery, immediately resalable, without restrictive legend and upon such resale freely transferable on the transfer books of the Company. (c) Unless otherwise agreed to by the Warrant Holder, the Call Notices must be given to all Warrant Holders who receive Warrants similar to this Warrant (in terms of exercise price and otherwise) on or about the same issue date as this Warrant in proportion to the amounts of Common Stock which can be purchased by the respective Warrant Holders in accordance with the respective Warrant held by each. (d) The Company may give a Call Notice in connection with up to 50% of the Common Stock issuable upon exercise of this Warrant provided the closing bid price of the Common Stock as reported by the Principal Market as defined in the Subscription Agreement, for each trading day during the thirty days prior to the giving of the Call Notice ("Lookback Period") is 200% of the Purchase Price and the average daily trading volume of the Common Stock during the Lookback Period is not less than 100,000 Common Shares. Subject to the other limitations set forth herein, the maximum amount of Warrant Shares for which Call Notices may be given during any thirty day period shall be equal to 10% of the aggregate reported trading volume of the Common Stock during the Lookback Period. (e) The respective Warrant Holders shall exercise their Warrant rights and purchase the appropriate Warrant Shares and pay for same within 14 business days of the date of the Call Notice. If the Warrant Holder fails to timely pay the funds required by the Warrant Call, the Company may elect to cancel a corresponding amount of this Warrant. (f) The Company may not exercise the right to Call this Warrant or any part of it after the occurrence of a Non-Registration Event, as defined in the Subscription Agreement, unless same were subject to cure and cured during the stated cure period.
