Investor Verification Checklist
- Verify the specific milestones required to unlock the $100.0 million tranche and extend the interest-only period.
- Review the exact definitions of "minimum revenue levels" and "liquidity levels" in the financial covenants (Exhibit 10.1).
- Assess the impact of the 7.60% interest rate floor on future interest expense.
- Confirm the status of the uncommitted $50.0 million tranche and the likelihood of mutual agreement with lenders.
- Examine the security interest granted over "substantially all assets" to understand potential restrictions on future financing or asset sales.
