                             PRESS RELEASE IMMEDIATE
                 THE FIRST OF LONG ISLAND CORPORATION ANNOUNCES
                   FIRST QUARTER EARNINGS AND ADDITIONAL SHARE
                                 REPURCHASE PLAN

      First Quarter Earnings. Glen Head, New York, April 24, 2003 - The First of
Long Island Corporation earned 74 cents per share for the first quarter of 2003
as compared to 62 cents for the same quarter last year, an increase of 19%. Net
income for the most recent quarter was $3,093,000 as compared to $2,648,000 a
year ago. Total assets were $803,691,000 at March 31, 2003.

      The most important reason for the growth in earnings was an unusually
large commercial mortgage prepayment fee. Other important causes of the earnings
increase include growth in checking balances, market type savings balances and
residential mortgages as well as a gain on the sale of securities. The large
prepayment fee, the recurrence of which is unlikely, was especially important to
the growth in earnings per share being equivalent to approximately 8 cents per
share.

      The Company continues to be challenged by the very low interest rate
market. The negative effects on net interest margin are expected to become even
more pronounced as loans and securities are repriced or reinvested at lower
yields without an offsetting reduction in the cost of funds. Also beginning to
adversely affect earnings are the expenses of certain growth strategies
including the costs of our three new commercial banking branches in Manhattan.
