Based on 12 million shares outstanding and the assumption of net debt outstanding as of September 30, 2006, the transaction is valued at $471 million. OSG financed the acquisition with borrowings under its revolving credit agreement and intends to repay up to $300 million of this amount from qualified withdrawals under its Capital Construction Fund (CCF). The transaction is expected to be immediately accretive to OSG's earnings, before consideration of any transaction synergies. Maritrans will be renamed "OSG America, Inc." As a result of the combination, OSG's U.S. Flag fleet now totals 35 operating and newbuild vessels that include handysize product carriers, a car carrier, dry bulk carriers and articulated tug barges. OSG's U.S. Flag fleet provides U.S.-based companies with a broad range of short-haul and long-haul transportation and lightering services. The strategic acquisition also gives OSG a presence in all four major U.S. trading routes.
