Exhibit 99.1 - Explanation of Responses
Exhibit 99.2 - Joint Filers' Information and Signatures

Stonehill Institutional Partners, L.P., a Delaware limited partnership (&quot;Partners&quot;), and Stonehill Master Fund, Ltd., a Cayman Islands exempted company (&quot;Master&quot;), are the direct holders of the shares reported herein. Due to the limitations on the number of reporting persons that may be included on a single Form 4, Partners is reporting the subject transaction and its beneficial ownership on a separate Form 4. The Power of Attorney given by each of Messrs. Motulsky, Wilson, Teetsel, Varkey, Sacks, Sisitsky, Thoyer and Stern was previously filed with the U.S. Securities &amp; Exchange Commission on February 24, 2014 as an exhibit to a statement on Form 4 filed by Stonehill Capital Management LLC with respect to WCIC and is hereby incorporated by reference. Solely for purposes of Section 16 of the Exchange Act, each of Partners and, by virtue of their control of Partners, Management and GP (as defined in Exhibit 99.1), may be deemed to be directors-by-deputization by virtue of Partners' contractual right to designate two members of the board of directors of WCIC. Christopher Wilson, a managing member of GP and Management, is a member of WCIC's board of directors.</remarks>
