Mr. Jamison expressed that his decision to resign as President and Chief Executive Officer was due, in part, to a disagreement regarding the consideration of alternatives to address the Company’s situation with the holder of its senior secured notes. In that regard, the other members of the Board note that the Company continues to pursue a variety of possible alternatives (within or outside of bankruptcy) for the benefit of all of its stakeholders, including vendors, customers and other creditors, as well as stockholders. That includes an ongoing process seeking a buyer of the Company or its business, in whole or in part.

Later that same day, Mr. Jamison stated that he was also resigning from the Board, effective August 22, 2023. In connection with Mr. Jamison’s resignation from the Board, the Board approved a reduction in the size of the Board from six members to five members, effective August 22, 2023.

On August 22, 2023, Mr. Flexon will assume the duties of the Company’s principal executive officer.

In connection with Mr. Flexon’s transition to Executive Chairman, Denise M. Wilson was appointed Lead Independent Director of the Board.

The Board has directed the Compensation and Human Capital Committee to recommend compensation arrangements for Mr. Flexon in connection with his appointments as Executive Chairman and Interim President and Chief Executive Officer. The Board has also directed the Governance and Sustainability Committee to commence a search for a permanent President and Chief Executive Officer.
