                          2003 Fourth Quarter Earnings
                           Operating income(1) up 90%
        15th straight quarter of double-digit commercial renewal pricing
                     GAAP combined ratio drops below 100.0%
                Book value per share up 12% for 2003, to $27.48


Branchville, NJ - Feb 3, 2004 - Selective Insurance Group, Inc. (Nasdaq: SIGI),
today reported net income of $23.8 million, or $0.86 per diluted share, for the
fourth quarter ended December 31, 2003, compared with $12.3 million, or $0.46
per diluted share, for the same period last year. Operating income(1) from
continuing operations increased 90%, to $20.9 million, or $0.75 per diluted
share for the fourth quarter 2003, compared with $11.0 million, or $0.41 per
diluted share for the fourth quarter 2002. Net premiums written increased 15% to
$271.4 million in fourth quarter 2003, compared with the same period last year,
and reached $1.2 billion for the year.

Fifteen consecutive quarters of double-digit commercial renewal price increases
produced more favorable commercial lines results. Strong pricing, together with
an improving personal lines automobile market, resulted in a drop in Selective's
GAAP combined ratio for the quarter to 99.5%, down from 103.2% for the fourth
quarter of 2002. For the same period, the statutory combined ratio improved
almost two points to 101.6%. For the full year, the GAAP combined ratio improved
to 102.2%, from 103.9% at

(1) Operating income from continuing operations differs from net income by the exclusion
    of realized gains or losses on investment sales, as well as net income from the
    discontinued software operation. It is used as an important financial measure
    by management, analysts and investors because the realization of investment gains
    and losses in any given period is largely discretionary as to timing and could distort
    the analysis of trends; however, it is not intended as a substitute for net income
    prepared in accordance with accounting principles generally accepted in the United States
    of America (GAAP). A reconciliation of operating income to net income is provided in
    the attached GAAP Highlights, and Reconciliation to Comparable GAAP Measures. Statutory
    data is prepared in accordance with statutory accounting rules as defined by the
    National Association of Insurance Commissioners Accounting Practices and Procedures
    Manual and, therefore, is not reconciled to GAAP.

the end of 2002, while the statutory combined ratio dropped to 101.5% at
year-end, from 103.2% in 2002.

Selective Insurance Group, Inc., Chairman, President and CEO Gregory E. Murphy
stated: "Our strong fourth quarter capped off a solid year, in which our
distinctive competitive positioning and growth strategies enabled us to reach
our goals, while accelerating our capacity for continued improvement. We
delivered an annual total return to our shareholders of 31.4%, a performance
that surpassed the S&P 500 and the S&P Property and Casualty indices.

"In our core commercial lines operation, which represents 82% of overall premium
volume, premium growth was 17% for the quarter, including $50 million in new
business. Commercial renewal price increases held steady at 11%, and averaged
13% for the full year. Our commercial outlook remains favorable as increases in
premiums continue to outpace loss trends. Operating cash flow also remained
strong during the quarter, up 50% over the prior year period to $74 million, and
reaching $282 million for the full year. We further narrowed the gap in our
personal lines statutory combined ratio, which includes our flood operations,
delivering a 101.8% for the quarter, down from 105.0% for the same period last
year. Our personal lines performance reflects ongoing improvements in our New
Jersey automobile business, which produced a statutory combined ratio below
100.0% for both the quarter and the year," Murphy said.

Revenue from continuing operations for the fourth quarter 2003 increased 16%
over fourth quarter 2002, to $359.2 million. Revenue growth for the quarter,
compared with the same period last year, reflected: continued increases in net
premiums earned, up 17% to $300.2 million; higher net investment income of $30.6
million, up 6%; and a 13% increase in revenue to $22.6 million from the
Company's Diversified Insurance Services operation. Return on revenue for the
diversified businesses improved to 5.3% for the quarter, compared with 3.9% in
fourth quarter 2002. Selective's overall revenue from continuing operations
reached $1.4 billion at year-end.


For the full year 2003, Selective's net income was $66.3 million, or $2.40 per
diluted share, compared with $42.0 million, or $1.56 per diluted share, in 2002.
Realized capital gains, after tax, for 2003 were $8.3 million, or $0.30 per
diluted share, compared with $2.1 million, or $0.08 per diluted share, in 2002.
For 2003, the Company had operating income(1) from continuing operations of
$58.0 million, or $2.10 per diluted share, compared with $40.0 million, or $1.49
per diluted share last year.

At Dec. 31, 2003, total assets reached $3.4 billion, including $2.4 billion in
the company's investment portfolio. Book value per share for the year grew 12%
to $27.48. The Board of Directors has declared a $0.17 per share quarterly cash
dividend on its common stock payable March 1, 2004, to stockholders of record on
Feb. 17, 2004.
