Explanation of Responses:

( 1 )Pursuant to a Master Loan Agreement (the "Agreement") entered into by Poseidon Bio, LLC ("Poseidon") and a third party lender (the "Lender"), on October 2, 2023, Poseidon delivered the Lender 500,000 shares of common stock, par value $0.0001 (the "Shares"), of Ocean Biomedical, Inc. (the "Issuer"), initially valued at $2,050,000 (the "Initial Value"). In connection with the transaction, the Lender is making a three-year, non-recourse loan to Poseidon of $777,500 (the "Loan"), equal to the Loan's gross proceeds of $820,000 (the "Gross Proceeds") less Loan fees. The Shares are not Loan collateral, as the Lender has the absolute right, title, and interest in and to the Shares, including the right to sell, transfer, encumber except for short selling, and vote the Shares. Despite the parties' intention for the Lender to transfer the Shares to Poseidon after the Loan is repaid (see footnote 2), the Lender may be deemed to beneficially own the Shares during the Loan term. ( 2 )On the maturity date of the Loan, which is expected to be on or about September 28, 2026 (the "Maturity Date"), Poseidon must pay the Lender (i) the Gross Proceeds, (ii) all unpaid accrued interest on the Loan, (iii) 100% of the excess, if any, of the value of the Shares at the Maturity Date over 125% of the Initial Value, and (iv) any other amounts that Poseidon owes the Lender under the Agreement (collectively, the "Repayment Amount"). Within five business days of Poseidon's payment of the Repayment Amount, the Lender must transfer the Shares to Poseidon, subject to the Lender's right to withhold and set off against the Shares any sums owed to the Lender by Poseidon under the Agreement. ( 3 )These securities are owned directly by Poseidon, a 10% owner of the Issuer, and indirectly by Dr. Chirinjeev Kathuria ("Dr. Kathuria"), as a Managing Director of Poseidon. Dr. Kathuria is also the Executive Chairman and a director of the Issuer. Dr. Kathuria disclaims beneficial ownership of the reported securities except to the extent of his pecuniary interest therein. ( 4 )These securities are owned directly by Dr. Kathuria.
