The name, citizenship, present principal occupation or employment and business address of each director and executive officer of Asgard I and Asgard II are set forth in Appendix A attached hereto.
	(b) The principal business address of each of the Reporting Persons is 2100 McKinney Avenue, Suite 1800, Dallas, TX 75201.
	(c) The principal business of the Funds and the Managed Account is to invest in securities. The principal business of Carlson Capital is to serve as the investment manager to the Funds and to certain managed accounts, including the Managed Account. The principal business of Asgard II is serving as the general partner of Carlson Capital. The principal business of Asgard I is serving as the sole stockholder of Asgard II. The principal occupation of Mr. Carlson is serving as President of Asgard II, Asgard I and Carlson Capital.

	From October 12, 2016 through November 18, 2016, the Reporting Persons sold 787,590 shares of common stock for an aggregate consideration of $10,174,865.
	The source of the funds used to acquire the Common Shares reported herein is the working capital of the Funds and margin borrowings described in the following sentence. Such Common Shares are held by the Reporting Persons in commingled margin accounts, which may extend margin credit to the Reporting Persons from time to time, subject to applicable federal margin regulations, stock exchange rules and credit policies. In such instances, the positions held in the margin account are pledged as collateral security for the repayment of debit balances in the account. The margin accounts bear interest at a rate based upon the broker’s call rate from time to time in effect. Because other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Shares reported herein.

(a)-(j) The Reporting Persons and their representatives intend, from time to time, to engage in discussions and correspondence with management and the Issuer’s Board of Directors (the “Board”) regarding, among other things, the Issuer’s business, management and strategic alternatives and direction. The Reporting Persons believe that the Issuer’s Common Shares trade at a substantial discount to the Issuer’s intrinsic value and represent an attractive investment opportunity.
