The Founder Shares included an aggregate of up to 1,100,000 shares, which were subject to forfeiture depending on the extent to which the underwriters’ over-allotment option was exercised within the 45-day period following the closing of the Initial Public Offering. The amount of the forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the underwriters so that the number of Founder Shares will equal 25% of the Company’s issued and outstanding shares after the Initial Public Offering and the private placement. In connection with the consummation of the private placement, Art Technology Sponsor, LLC forfeited 100,000 Founder Shares and Clear Street purchased 100,000 Founder Shares from the Company.

The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $2,500,000 of such Working Capital Loans may be convertible at the option of the lender into units upon consummation of the Business Combination at a price of $10.00 per unit.
