Yep, 8 (b) iv. does state: the Escrow Agent shall pay to Buyer the balance of any funds held by the Escrow Agent...
However you conveniently forgot, the Escrow Agent already handed over the $1,000,000.00 to Aerline on 9/1/17.
The Company previously made a good faith deposit of $1,000,000 with a third party escrow agent, which funds were released to AerLine on September 1, 2017.
