- Review the Supplemental Indentures (Exhibits 4.2 and 4.3) for specific definitions of "Fundamental Change" and "Make-Whole Fundamental Change."
- Monitor the Company's Common Stock price relative to the conversion prices ($104.56 and $118.50) to assess conversion risk.
- Confirm the impact of the new debt on the Company's existing debt covenants and credit ratings.
