                SUFFOLK BANCORP ANNOUNCES FIRST QUARTER EARNINGS

      Riverhead, New York, April 13, 2004 -- Suffolk Bancorp (NASDAQ - SUBK)
today released the results of its operations during the first quarter of 2004.
Net income for the first quarter was $4,864,000, down 8.9 percent from
$5,339,000 posted during the same period last year. Earnings-per-share for the
quarter were $0.45 compared to $0.47, down 4.3 percent. A detailed financial
summary follows the text of this release.

      President and Chief Executive Officer, Thomas S. Kohlmann, commented, "The
first quarter of 2004 presented several challenges. As has been the case this
past year or so, the most significant of these challenges is the compression of
our net interest margin. Interest rates have been lower, longer than at any time
during the past forty years. Yields on loans and other investments have dropped
by more than the rates paid for deposits which have less room to decline. The
result has been a decrease in net interest income."

      He went on to say, "Continued amortization and prepayment of consumer
loans have resulted in much greater liquidity, which, in turn, has been
reinvested at lower, current rates. This is a structural change in the
composition of our loan portfolio, brought about primarily by the financing
incentives of the major automobile manufacturers, including the so-called
"zero-zero" loans made to the most credit-worthy customers which require no down
payment and carry no interest. We believe that this trend will continue for the
foreseeable future."

      He continued, "To compensate for this, we have concentrated on commercial
lending, as well as commercial real estate and residential mortgages. Total loan
balances are actually ahead by 4.4 percent from the same time a year ago. We
have also kept a tight rein on expenses, which actually declined by 0.2 percent
while assets grew by 3.2 percent, versus March 31st of last year."

      He concluded, "By the most important measure of internal profitability,
Suffolk remains among the high performers in the industry, even in the face of
current challenges. Return on average equity was 19.57 percent in comparison to
the industry average of 12.29 percent for fourth quarter of 2003, the most
recent quarter for which data is available, or even to 13.79 percent for banking
companies with $1 to 5 billion in assets. While we manage Suffolk's core
business to weather all possible interest rate environments, we believe that in
the long term, the most likely direction for rates is up, and expect that there
will then be opportunities to widen the net interest margin."

      Suffolk Bancorp is a one-bank holding company engaged in the commercial
