SeaStar Medical Holding Corporation (the Company) has approved retention bonuses for two key executives, Eric Schlorff and Kevin Chung, to ensure their continued employment. Eric Schlorff is eligible for a total cash retention bonus of $200,000, payable in three installments: $66,666.66 on July 1, 2026, $66,666.67 on November 1, 2026, and $66,666.67 on March 1, 2027. Kevin Chung is eligible for a total cash retention bonus of $140,000, payable in three installments: $46,666.66 on July 1, 2026, $46,666.67 on November 1, 2026, and $46,666.67 on March 1, 2027. In addition to cash, the Compensation Committee may grant each executive a restricted stock unit (RSU) award equal to 25% of their aggregate retention payment. These RSUs would vest in three installments aligned with the cash payment schedule. Eligibility for these bonuses requires the executives to remain employed in good standing and perform their duties at an acceptable level through each respective retention period. If an executive is terminated without 'Cause' (as defined in the agreement, including material breach of policy, gross negligence, or acts of dishonesty), they will receive a pro-rated amount for the current upcoming payment. The agreements do not alter the at-will employment status of the executives.
