Explanation of responses

F1KKR Wand Investors L.P. initially acquired the 3.00% Series B Convertible Preferred Stock ("3% Series B Preferred Stock") on January 5, 2015. The terms of the 3% Series B Preferred Stock were amended and restated as 5.00% Series B Convertible Preferred Stock ("5% Series B Preferred Stock"), effective as of January 5, 2018. The two reported transactions reflect the amendment of the terms of the 3% Series B Preferred Stock, which may be deemed to result in the cancellation of the "old" 3% Series B Preferred Stock and the issuance of "new" 5% Series B Preferred Stock.
F2The holder of the 3% Series B Preferred Stock had no optional right to convert the 3% Series B Preferred Stock into common stock of the Issuer ("Common Stock"). All or a portion of the 3% Series B Preferred Stock would automatically convert into Common Stock on each date that the Issuer closed certain acquisitions described in the Certificate of Designations establishing the terms of the 3% Series B Preferred Stock. In the event of an automatic conversion, the 3% Series B Preferred Stock would convert into a number of shares of Common Stock equal to the $1,000 liquidation preference amount divided by a conversion price equal to the lesser of: (a) $2.25, and (b) the average of daily volume weighted average prices of the Common Stock during the 20 trading day period ending on the trading day immediately preceding the public announcement by the Issuer that it has entered into a definitive agreement for such acquisition, subject to a floor of $1.75 per share.
F3The 3% Series B Preferred Stock could be converted automatically until January 5, 2018, unless extended pursuant to the terms thereof. If all of the Series B Preferred Stock were converted at the floor price, the amount of shares of Common Stock issuable to the Reporting Persons would be 114,285,714 shares.
F4The holder of the 5% Series B Preferred Stock has no optional right to convert the 5% Series B Preferred Stock into Common Stock. All or a portion of the 5% Series B Preferred Stock automatically converts into Common Stock on each date that the Issuer closes certain acquisitions described in the amendment to the Issuer's Amended and Restated Certificate of Incorporation, which established the terms of the 5% Series B Preferred Stock. In the event of an automatic conversion, the 5% Series B Preferred Stock shall convert into a number of shares of Common Stock equal to the $1,000 liquidation preference amount divided by the fixed conversion price of $1.35 per share. The 5% Series B Preferred Stock may be converted automatically until October 5, 2019, except in certain circumstances, such period may be extended pursuant to the terms thereof.
