### Notes to Financial Statements
registration rights to include their securities in other registration statements filed by the Company. The Company will bear the expenses incurred in connection with the filing of any such registration statements. There will be no penalties associated with delays in registering the securities under the registration rights agreement.

#### Underwriters Agreement
The Company granted the underwriters a 45-day option to purchase up to 3,000,000 additional Public Units to cover any over-allotments, at the Offering price less underwriting discounts and commissions. On September 28, 2021, the over-allotment was exercised in full by the Underwriters.

The Company paid an underwriting discount of $0.20 per Public Unit to the Underwriters at the closing of the Offering. The underwriting discount was paid in cash.
