VTG purchase price is $667 million f or a comparable drillship (Platinum Explorer firm order). (b) TMT is f inancing Platinum Explorer construction payments. Payment to seller will be 30% in September 2008 f or the drillship with balance due at delivery. Savings based on a construction loan assuming 8% interest, 30% down payment, 25% at close and 5 equal installments over 3 y r construction period. (c) Jackup deliveries are accelerated on average by 12 months versus a newbuild ordered today. The jackups were purchased at market rates, thus the value embedded in early delivery is approximately $30 to $40 million per rig (dayrate range of $185 to $215 discounted at 12%). (d) Current market price for a BMC 375 jackup is estimated to be $238 million (based on recent Scorpion Offshore purchase offer) compared to Vantage purchase price of $220 million apiece. (e) Assumes exercise of all warrants outstanding which will provide cash to VTG and thus reducing maximum debt outstanding.
