PRESS RELEASE

FOR IMMEDIATE RELEASE


                   NORTH FORK BANCORPORATION, INC. TO ACQUIRE
                JSB FINANCIAL, INC. IN A COMMON STOCK TRANSACTION
                      VALUED AT APPROXIMATELY $570 MILLION

         MELVILLE, N.Y. - AUGUST 16, 1999 - NORTH FORK BANCORPORATION, INC.,
(NYSE:NFB) AND JSB FINANCIAL, INC. (NYSE:JSB) jointly announced today that they
have signed a definitive merger agreement whereby North Fork Bancorporation,
Inc. ("North Fork") would acquire JSB Financial, Inc. ("JSB") in a
stock-for-stock merger valued at approximately $570 million. JSB is the holding
company for Jamaica Savings Bank FSB, a savings institution with branch
locations in the New York Metropolitan area. Under terms of the agreement, each
share of JSB will be converted into North Fork common stock at a fixed exchange
ratio of three shares of North Fork for each share of JSB. Approximately 27.9
million shares of North Fork will be issued in connection with the merger. It is
expected that it will be accounted for as a pooling-of-interests transaction for
financial reporting purposes and will be a tax-free reorganization. The merger
agreement, however, is not conditioned upon such accounting treatment. The
exchange ratio was based upon the price of North Fork's stock utilizing its
closing price on August 13, 1999 of $20.44 for a total value to JSB shareholders
of $61.31. The closing price of JSB common stock on that date was $58.75. The
merger is expected to close in the first quarter of 2000 following receipt of
all regulatory approvals and approval by the shareholders of both companies. Due
diligence by both companies has been completed. The agreement provides that
North Fork receives an option to acquire up to 19.9% of JSB's outstanding shares
at $58.75 per share should certain events occur. Also, JSB has a right to
terminate the agreement should the closing price of North Fork's shares decline
beyond a specified price and index, unless North Fork elects to increase the
exchange ratio.

         The combination will increase North Fork's stated and tangible book
value per share by 25% and 30%, respectively, to $7.18 and $6.70. It is also
expected to be accretive to North Fork's earnings per share by $0.03 in the full
year 2000. Additionally, North Fork's projected capital ratio will be 10.4% or
an increase of 22%. North Fork's common shares outstanding will rise to
approximately 171 million for an estimated market capitalization of $3.4
billion. "Mr. Adikes and his entire board should be commended for having created
and preserved the value of this pristine organization. This balance sheet speaks
for itself. We are proud to have been selected as their merger partner," stated
John Adam Kanas, Chairman, President and Chief Executive Officer of North Fork.
He went on to say "The consummation of this transaction is very encouraging. We
believe it marks the return of a more rational trend in thrift consolidation to
this market."



         JSB had total assets of $1.6 billion, deposits of $1.2 billion and
stockholders' equity of $375 million at June 30, 1999. It conducts its business
from thirteen full service offices: ten located in the New York City borough of
Queens, one in the borough of Manhattan and two on Long Island. All of these
locations are complimentary to North Fork's branch network and will remain after
the merger is complete. JSB has consistently ranked among the highest performing
thrift companies in the nation. This well managed company brings a stable
deposit base, access to many customers and a solid capital position to the
combination with North Fork. Park T. Adikes, Chairman and Chief Executive
Officer of JSB will join North Fork's Board of Directors. "In this transaction,
our shareholders and employees will become part of one of the best performing
banks in the country. We are excited about the prospects of our future
together," stated Mr. Adikes.

         Following the merger, North Fork will have approximately $13.2 billion
in assets, deposits of $7.6 billion and stockholders' equity of $1.2 billion. In
connection with the merger, North Fork will reissue approximately seven million
shares purchased under its 10% share repurchase program. Simultaneously, with
the approval of the merger transaction, North Fork's Board of Directors
rescinded the share repurchase program.

         NORTH FORK PLANS AN ANALYST CONFERENCE CALL FOR TUESDAY, AUGUST 17,
1999 AT 2:00 P.M. EDT, to elaborate on the strategic rational and financial
implications of the acquisition. THE TELEPHONE NUMBER TO CALL IN THE UNITED

         This press release contains certain forward looking statements with
respect to the financial condition, results of operations and business of North
Fork following the consummation of the merger that are subject to various
factors which could cause actual results to differ materially from such
projections or estimates. Such factors include, but are not limited to, the
possibility that anticipated cost savings and revenue enhancements might not be
realized and that adverse general economic conditions or an adverse interest
rate environment could develop. North Fork's current report on Form 8K filed on
or about August 16, 1999 discloses more fully these factors.

         North Fork, with total assets of approximately $11.5 billion, operates
over 110 branch locations throughout the New York Metropolitan area and
Connecticut. It is ranked among the Top 50 Commercial Bank Holding Companies in
the United States, and its profitability and efficiency are ranked among the
industry's best.
