Mandate to Structure and Arrange Debt Finance Facilities

Seascape Energy, an E&P company focused on Southeast Asia, is pleased to announce that it has exclusively mandated Macquarie Bank Limited ("Macquarie") to act as the sole Structuring Bank and Technical and Modelling Bank for the debt financing to support the development of the DEWA Cluster (SEA 28%) and Temaris Cluster (SEA 100%) gas fields, offshore Malaysia.

Seascape will work together with Macquarie over the coming months to structure and execute a multi-tranche, debt facility to meet development expenditure with availability linked to certain milestones typical for this type of financing. Any firm offer of financing remains subject to the successful completion of legal and technical due diligence and Macquarie's receipt of all required internal approvals.

Nick Ingrassia, CEO of Seascape, commented:

"Macquarie Bank has a long history of deploying capital to support growth-focused E&P companies like Seascape. We are extremely pleased they have committed to work with us to secure financing to develop these important gas projects to secure domestic supply into Malaysia and regional export markets."
