ITEMS 1 THROUGH 4.      NOT APPLICABLE.

ITEM 5.           OTHER EVENTS.

         On August 16, 1999, JSB Financial, Inc., a Delaware corporation
("JSB"), announced that it had entered into an Agreement and Plan of Merger,
dated as of August 16, 1999 ("Merger Agreement"), with North Fork
Bancorporation, Inc., a Delaware corporation ("NFB"). NFB is the bank holding
company parent of North Fork Bank and Trust Company, a New York State chartered
stock commercial bank. The Merger Agreement provides, among other things, that
JSB will merge with and into NFB, with NFB being the surviving corporation
("Merger"). A copy of the Merger Agreement is attached hereto as Exhibit 2.1.
Capitalized terms which are used but not defined herein shall have the meanings
ascribed to such terms in the Merger Agreement.

         Pursuant to the Merger Agreement, each share of JSB common stock, par
value $0.01 per share ("JSB Common Stock"), issued and outstanding immediately
prior to the Effective Time will be converted into and become the right to
receive 3.0 shares of NFB common stock, par value $2.50 per share ("NFB Common
Stock"), except for (i) shares of JSB Common Stock held directly or indirectly
by NFB, other than shares held in a fiduciary capacity in satisfaction of a debt
previously contracted, and (ii) shares held by JSB as treasury stock. Each
holder of JSB Common Stock who would otherwise be entitled to receive a fraction
of a share of NFB Common Stock will receive an amount in cash equal to the
product arrived at by multiplying such fraction of a share of NFB Common Stock
by the NFB Market Value.

         The Merger will be structured as a tax-free reorganization and it is
expected that it will be accounted for as a pooling-of-interests; the Merger
Agreement, however, is not conditioned upon such accounting treatment.
Consummation of the Merger is subject to the satisfaction of certain customary
conditions, including approval of the Merger Agreement by the stockholders of
both JSB and NFB and approval of the appropriate regulatory agencies.

         JSB has the right to terminate the Merger Agreement if (i) the NFB
Market Value on the Valuation Date falls below $16.35 per share and (ii) such
decline in value is 10% greater than the percentage decline of the shares of
stock of a group of similar financial institutions over the same period, unless
NFB elects to increase the Merger Consideration to be received by JSB's
stockholders as set forth in the Merger Agreement.

         The Merger Agreement also provides that options to purchase shares of
JSB Common Stock under JSB's stock option plans that are outstanding at the
Effective Time shall be converted into options to purchase shares of NFB Common
Stock in accordance with the procedure set forth in the Merger Agreement. In
connection with the Merger Agreement, JSB granted to NFB a stock option pursuant
to a Stock Option Agreement, dated as of August 16, 1999, which, under certain
defined circumstances, would enable NFB to purchase up to 19.9% of JSB's issued
and outstanding shares of common stock. The Stock Option Agreement provides that
the total profit receivable thereunder may not exceed $30 million plus
reasonable out-of-pocket expenses. A copy of the Stock Option Agreement is
attached hereto as Exhibit 4.1.

         JSB and NFB publicly announced the Merger in a press release dated
August 16, 1999, a copy of which is attached hereto as Exhibit 99.1.

         The press release and analyst presentation incorporated by reference
herein may contain certain forward-looking statements with respect to the
financial condition, results of operations and business of NFB following the
consummation of the Merger, including statements relating to (a) the expected
cost savings and revenue enhancements to be realized from the Merger and (b)
projected 2000 pro forma earnings per share. Factors that may cause actual
results to differ materially from those contemplated by such forward-looking
statements include, among others, the following possibilities: (1) expected cost
savings or revenue enhancements from the Merger cannot be fully realized; (2)
deposit attrition, customer loss or revenue loss following the Merger is greater
than expected; (3) competitive pressure in the banking and financial services
industry increases significantly; (4) changes in the interest rate environment
reduce margins; (5) general economic conditions, either nationally or in the
State of New York, are less favorable than expected; (6) changes in real estate
values; (7) changes in accounting principles; (8) changes in legislation; (9)
changes in other economic, governmental, regulatory and technological factors
affecting each company's operations, pricing, products and services; and (10)
the impact of the Year 2000
