Black Hawk Acquisition Corp (BKHA) entered into a series of financing agreements with Meteora Select Trading Opportunities Master, LP in connection with its pending business combination with Vesicor Therapeutics. The agreements include a Forward Purchase Agreement for up to 1,350,000 shares, a Non-Redemption Agreement covering up to 2,124,077 shares, a Subscription Agreement, and a Standby Equity Purchase Agreement (SEPA) allowing PubCo to sell up to $200.0 million of common stock over 36 months.

• · The Non-Redemption Agreement provides for a payment to Meteora of the final per-share redemption price less $0.75 per Backstop Investor Share.
• · The SEPA has no mandatory minimum utilization amount and no non-usage fee.
