F6

On November 3, 2026, approximately 1.8% of the membership interest in the Sponsor was transferred from RedemptionCo to PSH for aggregate cash consideration of $806,976.20 in connection with the ongoing liquidation of RedemptionCo (the foregoing transfer, the "SPARC Membership Transfer"). RedemptionCo was formed for the purpose of giving effect to the redemption of certain limited partner interests of PSLP in connection with a special redemption opportunity that was consummated on April 21, 2026, and RedemptionCo is intended to be liquidated following the fulfillment of that purpose.

Referenced by the price of 2 transactions in Table I and 2 transactions in Table II.

F7

The SPARC Membership Transfer did not result in a change of aggregate ownership of the Issuer's Common Stock and Sponsor Warrants by the Sponsor.

Referenced by the price of 2 transactions in Table I and 2 transactions in Table II.

Remarks
