In consideration of Seller extending the Closing Date as provided in Paragraph 2 above, Buyer shall pay to Seller an extension fee by depositing in escrow with Escrow Holder, in cash or current funds, a sum of Two Hundred Fifty Thousand Dollars ($250,000.00) (the “Additional Extension Fee”) by no later than March 8, 2023.
