12-Year Charters Arranged with Mitsui O.S.K. Lines, Ltd.

HONG KONG, CHINA - Aug. 8, 2006 /CNW/ - Seaspan Corporation ("Seaspan") (NYSE:SSW) today announced that it has signed contracts to build four 5100 TEU vessels at Hyundai Heavy Industries Co., Ltd. in South Korea. These new orders will increase Seaspan's total fleet to 37 vessels. The four newbuilding vessels will be delivered between April and December 2009. The total delivered cost is expected to average approximately $83.4 million per vessel, subject to certain pre-delivery expenses remaining at budgeted levels.

Seaspan also announced that it has arranged simultaneous twelve-year charter agreements for these four vessels with Mitsui O.S.K. Lines, Ltd. ("MOL") of Japan at a rate of $28,880 per day. MOL is one of the largest global shipping companies and its container line is the world's 11th largest in terms of TEU capacity.

Each new vessel is expected to contribute between $8.5 million and $9.0 million in incremental EBITDA per annum upon delivery. For this purpose, EBITDA (which is a non-GAAP measure) means net earnings before interest, undrawn credit facility fees, taxes, depreciation and amortization of deferred financing fees. This should result in an increase in distributable cash when the vessels are delivered and operating. The 5100 TEU vessel size will complement Seaspan's existing fleet consisting of 9600 TEU, 8500 TEU, 4250 TEU, 3500 TEU and 2500 TEU vessels.

"We are extremely excited to enter into our first charters with a Japanese liner major," said Gerry Wang, Chief Executive Officer of Seaspan. "MOL is a wonderful addition to our portfolio of customers with their investment grade credit rating and excellent business reputation. In addition, we are pleased to execute our first shipbuilding contracts with HHI, the global leader in the construction of container vessels. This project brings diversification in terms of customer, vessel size and shipbuilder to our company while meeting our strict return and credit risk criteria."

Seaspan Management Services Limited ("SMSL") will supervise the construction of the new vessels and, upon their delivery, operate the ships for Seaspan at an expected rate of $4,800 per day.

HHI, based in Ulsan, South Korea, is world's largest shipbuilder and has built over 270 containerships during its 34 years in operation.

The company is in the process of arranging long-term debt financing for this order.
