Note 1:

Represents the effective date of the Founders Agreement of each subsidiary/partner company. Each PIK dividend and equity fee is payable on the annual anniversary of the effective date of the original Founders Agreement or has since been amended to January 1 of each calendar year.

Note 2:

Instead of a PIK dividend, Checkpoint paid the Company an annual equity fee in shares of Checkpoint’s common stock equal to 2.5% of Checkpoint’s fully diluted outstanding capitalization. Due to the deconsolidation of Checkpoint in May 2025 related to the Sun Pharma transaction (see Note 3), Checkpoint no longer has this obligation to the Company.

Note 3:

Represents the Trigger Date, the date that the Fortress partner company/subsidiary first acquires, whether by license or otherwise, ownership rights in a product.
