Signature Bank Completes Public Offering

Offering Significantly Increased By 35 Percent Due to Overwhelming Demand

New York…September 15, 2008…Signature Bank (Nasdaq: SBNY), a New York-based full service commercial bank, announced today the completion of its public offering of 5.4 million shares of common stock at $29 per share, including the over allotment of 700,000 shares exercised by the underwriters.  The offering was originally scheduled for 3.5 million shares and was increased due to overwhelming demand of the investment community.  The net proceeds to Signature Bank from the offering were approximately $148.0 million, after the deduction of underwriting discounts and commissions as well as offering expenses.  This offering increases the capital of the Bank to nearly $575 million and brings its current market capitalization to more than $1 billion.

Proceeds from this offering will be used to continue the Bank's growth in its niche market for privately owned businesses in the metro-New York area.

"This raising of capital was truly a monumental event for our Bank and it absolutely reflects the investment community's confidence in our fundamental banking strategy and ability to deliver.  The Bank is now in an even stronger position in the marketplace, which will allow us to better and more effectively compete with the mega-banks throughout metro-New York," said Joseph J. DePaolo, president and Chief Executive Officer.

"Since our inception in 2001, Signature Bank has maintained a pristine balance sheet with capital ratios far superior to those of our competitors. The reputation we have garnered served as a catalyst in our raising these significant funds, despite the highly tumultuous banking environment. This additional funding further strengthens our position as the premiere mid-size commercial bank headquartered in the metro-New York area," DePaolo explained.

"We have always believed that maintaining a strong balance sheet is at the core of the Bank's foundation and positions us as a financially sound institution -- one that is built to weather any changes that are presented within an economic cycle. Our goal is not to be the biggest bank but the best bank in terms of prudence with funds and service to our clients. With the success of this equity offering, we will continue to focus on expanding our business by serving a key niche primarily comprised of privately owned businesses and providing a single point of contact to meet all client needs," said Scott A. Shay, Chairman of the Board.

Friedman, Billings, Ramsey & Co., Inc. acted as lead manager in Signature Bank's offering. Oppenheimer & Co. Inc. and Sandler O'Neill + Partners L.P. served as co-managers.
