REASONS FOR ENTERING INTO THE AGREEMENT

The Company is now positioned to advance its offering of products and services through this strategic alliance with CSSC Huangpu and Zentech on Jack-up rigs operating beyond 300 feet water depth. The growing demand for these new designs operating in deeper waters offers a unique opportunity to the Company through the Contract. The transaction arising from the Contracts will be conducted in the ordinary and usual course of business of the Company.

To the best of the knowledge, information and belief of the Board having made all reasonable enquiries, CSSC Huangpu is an independent third party not connected with the Directors, chief executive or substantial shareholders of the Company or any of its subsidiaries or their respective associates and is not a connected person of the Company (as defined in the Rules Governing the Listing of Securities on the Stock Exchange of Hong Kong Limited).

REASONS FOR AND BENEFITS OF ENTERING INTO THE CONTRACTS

The Company has successfully grown from a provider of individual offshore equipment and services to being an integrated solutions provider of complete mission critical drilling packages for the oil drilling industry. The Company has already provided several drilling packages on Jack-up rigs and this will be the 9th jack-up drilling package for the Company. The alignment of the long term strategies of the Company, Huangpu Shipyard and Zentech in the trilateral strategic alliance enables them to integrate their core competencies to provide customers with advanced jack-up drilling rigs which meets with the growing demand for high performance rigs. The three partners of the alliance will continue to cooperate and promote more drilling platforms in the future to meet this growing demand.
