BlueMountain Capital Management, LLC ("BMCM") is the investment manager of BMM and BMLSC, and in that capacity directs the voting and disposition of securities held by each of them and receives an asset-based fee with respect to their investment activities. As BMCM acts as investment manager for each of BMM and BMLSC, its pecuniary interest in the Common Stock did not change.
