Twelve-Year Time Charters Arranged with COSCON Expected Annualized EBITDA to Increase by $136 Million to over $500 Million by 2012 Company to Host Conference Call and Webcast on Tuesday, September 11

HONG KONG, CHINA - Sept. 10, 2007 /CNW/ - Seaspan Corporation ("Seaspan") (NYSE:SSW) announced today that it has signed contracts to build eight new 13,100 TEU container vessels with Hyundai Heavy Industries Co., Ltd. and its subsidiary, Hyundai Samho Heavy Industries Co., Ltd. (collectively "HHI"). The contract price per vessel is approximately $165 million resulting in an expected delivered cost per vessel of approximately $181 million.

The eight new buildings are scheduled to be delivered between January 2011 and October 2011. With these agreements, Seaspan has expanded the company's contracted fleet to a total of 63 vessels. Currently, 20 of Seaspan's 34 vessels on order are with HHI, the largest shipbuilding company in the world.

Seaspan also announced that all eight vessels have been simultaneously signed to 12-year time charters with COSCO Container Lines Co., Ltd. ("Coscon") of Shanghai, one of the largest container liner shipping companies in the world. The time charter rate is $55,000 per vessel per day for the duration of the contract, again with no commissions or broker fees. Seaspan Management Services Limited will supervise the construction of the vessels and then operate the ships at an estimated fixed rate of $6,750 per day per vessel from delivery.

Upon delivery, based on these operating fees, each new vessel is expected to contribute more than $17 million in incremental EBITDA per annum for a total exceeding $136 million for all eight vessels. EBITDA is a non-GAAP measure defined as net earnings before interest, undrawn credit facility fees, taxes, depreciation and amortization of deferred financing fees.

Gerry Wang, Chief Executive Officer of Seaspan, stated, "Building on the success of our agreement to charter eight new 8,500 TEU vessels in April of 2007, we are pleased to further strengthen this strategic relationship with Coscon. Their position as the largest China-based container line and 7th largest in the world combined with their stellar credit quality adds considerable value to this investment. In addition, we believe this transaction for super-sized container vessels demonstrates Seaspan's ability to conduct large-scale, cost-efficient deals in this important asset class."

Wang added, "Consistent with our objective to secure our vessels on long-term fixed-rate charters with leading global customers, our 12-year charters for each of the eight newbuildings provide stable cash flows for Seaspan. With 22 newbuilding contracts already announced to date in 2007, Seaspan continues to successfully execute its growth strategy."

"Currently, we have 34 vessels scheduled to be delivered between 2008 and 2011 which will generate predictable and growing cash flows resulting in annual revenues of $640 million and annual EBITDA exceeding $500 million by the end of 2011. By significantly expanding our earnings power as we further grow our fleet, we have enhanced our ability to increase distributable cash flow over the long term."

Seaspan plans to initially fund the first installments of its eight new 13,100 TEU container vessels through its existing $1.3 billion revolving credit facility. Permanent financing for this transaction is expected to be concluded in the following months.

Seaspan plans to host a conference call for all shareholders and interested parties on September 11, 2007 at 8:30 a.m. ET to discuss the transaction.
