The Lessee agrees that the Lessor has no liability or obligation with respect to the Emission Scheme and the Lessee will indemnify and hold harmless the Lessor in the event that a demand for Emissions Allowances is levied against the Lessor or any penalty, fine or regulatory sanction or measure is taken against the Lessor with respect to any non-compliance with the Emission Scheme. The Lessor agrees to assist the Lessee in relation to any procedures/proceedings under the Emissions Scheme by, including but not limited to, providing timely any necessary information, documents, consents or authorisations as may be needed;

within five (5) days of the First Supplemental Agreement, (and in any case no later than 26 March 2024, the Lessor and the Lessee will execute the mandate letters in a form acceptable to the Lessor and the applicable administering authority (the “Applicable Administering Authority”) and the Lessee shall provide such mandate letters to the Applicable Administering Authority under which the Lessee or the Vessel’s relevant Manager, as the case may be, will establish a maritime operator holding account in order for the Lessee to (A) communicate to the Applicable Administering Authority the existence of the Charter and (B) mandate an organisation to comply with obligations under the EU ETS Legislation on its behalf;

the Lessee shall report to the Lessors in writing latest by November of each calendar year, commencing in November 2025, that they have surrendered the necessary allowances for the preceding calendar year in accordance with the Emission Scheme;

other than in cases of redelivery of the Vessel pursuant to the exercise of the Purchase Obligation or Purchase Option by the Lessee, one month before redelivery of the Vessel to the Lessor, the Lessee will provide the Lessor with full details of (A) the emissions of the Vessel during the preceding and current calendar year and provide the necessary and available at that time verified emissions data to permit the Lessor to verify the estimated liability of the Lessor for the surrender of Emission Allowances after the end of this Charter and (B) the number of Emission Allowances that are held in the Lessee’s or relevant Manager’s, as the case may be, maritime operators holding account in relation to the Vessel. The Parties will discuss and agree with full transparency and in good faith the number of Emissions Allowances that may be due to be surrendered by the Lessor on 30 September after redelivery of the Vessel that relate to emissions during the period of the Charter to permit the Lessor (if so required) to be in a position to comply fully with their obligations under the Emission Scheme. In such case and on redelivery of the Vessel to the Lessor under this Charter, the Lessee or the mandated relevant Manager of the Vessel will transfer the agreed number of Emission Allowances to the Lessor nominated account; additionally, the Lessor shall in good faith provide any documents, consents or information that may be requested by the Applicable Administering Authority to evidence that the Lessee or the relevant Manager of the Vessel is no longer responsible under the Emission Scheme; and

other than in relation to the Emission Scheme, should the Lessee trade into any country or region where the emissions from burning of Lessee’s bunkers are taxed, charged or otherwise give rise to a liability requiring offset, the Lessee will settle the liability directly with the relevant administering authority where possible or otherwise indemnify the Lessor for such liability. Parties expressly agree that known schemes such as carbon trading schemes or imposition of new dues by princes, powers or rulers shall not give rise to changes in the hire due under this Charter.

by replacing the words “as a ▇▇▇▇▇▇▇▇ Islands ship” in the first line of paragraph (a) of clause 57.2 with the words “under the Flag State”.

The Lessee undertakes that, no later than 29 March 2024, it will:
