REASONS FOR ENTERING INTO THE CONTRACT

TSC is now positioned to advance its offering of products and services through this strategic alliance with CSSC Huangpu and Zentech Incorporated on Jack-Up rigs operating beyond 300 foot water depths. The growing demand for these new designs operating in deeper waters offers a unique opportunity to TSC through the Contract. The transaction arising from the Contract will be conducted in the ordinary and usual course of business of the Company. The Rig is intended for sale to a leasing company who will purchase the Rig to be leased to a lessee or for outright sale to a prospective customer. The ultimate owner of the Rig, either the finance leasing company or the ultimate customer will take up the obligations under the payment terms of the Contract or such other terms that may be renegotiated between the parties. In either of the above events, the Company will be in a position to make a profit from the sales of the Rig. The Company expects that the transaction may provide positive revenue growth to the Group.
