(3) Exercise of Option. Lorus may exercise the Option at any time within thirty (30) days of receipt of the notice and offer by giving written notice to that effect to EMBI. The failure by Lorus to give such notice shall constitute an election by Lorus not to exercise the Option.

Lorus shall be entitled to require evidence of the date upon which and the price at which EMBI has sold the Bulk IP, and evidence that such sale has been completed upon the terms and conditions contained in the offer.

(5) Failure to Complete Sale. If the transaction of purchase and sale to such Offeror has not been completed within the said one hundred and eighty (180) day period, the foregoing provisions of this Section 7 shall again apply in respect of the proposed transfer of the Bulk IP and so on from time to time.

(6) Sale to EMBI. If Lorus exercises the Option as aforesaid, EMBI shall sell to Lorus and Lorus shall purchase from EMBI the Bulk IP in accordance with the terms of the offer as modified by the provisions of Subsection 6.02.
