The Merger Agreement was executed on March 24, 2025, and execution counterparts have been exchanged between Calderwood & Harkness and seller's counsel, Caldwell, Raines & Sheppard LLP (Patricia Okonkwo).

The draft credit agreement has been circulated among the lending group (Stonebridge, Birchwood Capital Finance LLC, and Ironvale Credit Fund III LP). We would expect comments from the co-lenders to be consolidated and returned at your convenience (see request below).
