[Folsom, NJ] -- South Jersey Industries (NYSE:SJI) today declared its regular
dividend of $0.425 for the second quarter of 2005. The dividend is payable July
5, 2005, to shareholders of record at the close of business June 10, 2005. This
is SJI's 54th consecutive year of paying dividends, reflecting the company's
commitment to a consistent, sustainable dividend.

The record date for the dividend is the same record date that was previously
announced for SJI's upcoming 2 for 1 stock split. Shares associated with the
split will be distributed on June 30, 2005. Consequently, SJI's stock will begin
trading at the post-split price on July 1, 2005.

The $0.425 dividend announced today was declared on a pre-split basis. On a
post-split basis, the dividend per share would be half of that amount, or
$0.2125, on twice as many shares.
