The Additional Notes are secured by a pledge of 65% of the stock of each of the Company's current foreign subsidiaries. As a result of this transaction, the exercise price of the Company's outstanding warrants to purchase shares of common stock issued in February 2010 will be adjusted downward when the Additional Notes are issued, and there will be a corresponding increase in the number of shares of common stock issuable upon exercise of such warrants. Upon the filing of a preliminary proxy statement for the approval of the issuance of the shares issuable for the above acquisition, all of the convertible promissory notes previously issued pursuant to the Note Purchase Agreement in February 2013 will automatically convert into shares of the Company’s common stock pursuant to their existing terms and at their existing conversion price of $1.30 per share, subject to a limitation prohibiting any such holder from holding more than 19.99% of the Company's common stock following such conversion. Cyrus and the other convertible debt holders will convert approximately 81% of their currently outstanding convertible notes into shares of Overland common stock. The preliminary proxy statement was filed on November 8, 2013, and the Company issued 8,247,896 shares of common stock in satisfaction of 81% of the Company's outstanding convertible notes at September 30, 2013. On November 12, 2013, the Company completed a private placement of $3.0 million of the Additional Notes. Issuance of Common Stock for Payment of Interest On November 8, 2013, the Company issued an aggregate of 379,310 shares of common stock at $0.98 per share to the holders of its outstanding convertible notes as payment of interest on such notes, which was payable upon conversion of the convertible notes.
