HONG KONG, CHINA -- (MARKET WIRE) -- 03/30/07 -- Seaspan Corporation ("Seaspan") (NYSE: SSW) today announced that it has signed contracts to build two 2500 TEU vessels at Jiangsu Yangzijiang Shipbuilding Co. Ltd. ("Jiangsu") in China. These new orders are in addition to the eight 2500 TEU vessels Seaspan ordered from Jiangsu in 2006. The two newbuilding vessels will be delivered in March and June, 2010. The total delivered cost is expected to be approximately $46.4 million per vessel, subject to certain pre-delivery expenses remaining at budgeted levels.

Seaspan also announced that it has arranged simultaneous ten-year charter agreements for these two vessels with Kawasaki Kisen Kaisha, Ltd. ("K-Line") of Japan at a rate of $17,880 per day. K-Line is Japan's third-largest liner operator and is ranked 13th in the world by TEU capacity.

Each new vessel is expected to contribute between $4.5 million and $4.9 million in incremental EBITDA per annum upon delivery. For this purpose, EBITDA shall mean 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.

"We are very pleased to expand our customer base by adding another major Japanese line to our portfolio," said Gerry Wang, Chief Executive Officer of Seaspan. "This acquisition also expands our relationship with Jiangsu as we now have ten 2500 TEU vessels in line to be delivered over the next three years from this shipbuilder. Given the large number of ships in this series, we expect to realize significant economies of scale in the design, outfitting and construction supervision costs of these vessels."

Seaspan Management Services Limited will supervise the construction of the new vessels and operate the ships for Seaspan at an estimated fixed rate of $4,200 per day through 2011.

The company will use its existing credit facility to fund the down payments for these vessels. Permanent financing will be arranged in the coming months.
