Contingencies and Conditions:

  • Waiver Mechanism: Conifer may request once per calendar year that the Company seek waivers from vehicle manufacturer agreements to allow ownership above the 19% cap, but only if the excess results from Company stock repurchases or redemptions.
  • Termination: The agreement terminates 30 days prior to the nomination notice deadline for the 2030 annual meeting, unless automatically extended based on re-nomination intent and Mr. Hart's continued association with Conifer.

Investor Verification Checklist

  • Verify the exact beneficial ownership percentage of Conifer Management as of the filing date to confirm compliance with the 19% standstill cap and 5% minimum threshold.
  • Review the full text of the Stockholder Agreement (Exhibit 10.1) for specific definitions of "Extraordinary Transactions" and "Open Windows."
  • Confirm the status of any pending waivers with vehicle manufacturers regarding the 19% ownership limit.
  • Monitor the Company's 2026 Definitive Proxy Statement for details on director compensation consistent with Mr. Hart's appointment.
